Brain Death: A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death. (From Adams et al., Principles of Neurology, 6th ed, pp348-9)Death: Irreversible cessation of all bodily functions, manifested by absence of spontaneous breathing and total loss of cardiovascular and cerebral functions.Tissue Donors: Individuals supplying living tissue, organs, cells, blood or blood components for transfer or transplantation to histocompatible recipients.Tissue and Organ Procurement: The administrative procedures involved with acquiring TISSUES or organs for TRANSPLANTATION through various programs, systems, or organizations. These procedures include obtaining consent from TISSUE DONORS and arranging for transportation of donated tissues and organs, after TISSUE HARVESTING, to HOSPITALS for processing and transplantation.Cell Death: The termination of the cell's ability to carry out vital functions such as metabolism, growth, reproduction, responsiveness, and adaptability.Cause of Death: Factors which produce cessation of all vital bodily functions. They can be analyzed from an epidemiologic viewpoint.Brain Injuries: Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.Brain Chemistry: Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states.Tissue and Organ Harvesting: The procedure of removing TISSUES, organs, or specimens from DONORS for reuse, such as TRANSPLANTATION.Apnea: A transient absence of spontaneous respiration.Coma: A profound state of unconsciousness associated with depressed cerebral activity from which the individual cannot be aroused. Coma generally occurs when there is dysfunction or injury involving both cerebral hemispheres or the brain stem RETICULAR FORMATION.Personhood: The state or condition of being a human individual accorded moral and/or legal rights. Criteria to be used to determine this status are subject to debate, and range from the requirement of simply being a human organism to such requirements as that the individual be self-aware and capable of rational thought and moral agency.Persistent Vegetative State: Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.Brain Neoplasms: Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.Organ Transplantation: Transference of an organ between individuals of the same species or between individuals of different species.Life: The state that distinguishes organisms from inorganic matter, manifested by growth, metabolism, reproduction, and adaptation. It includes the course of existence, the sum of experiences, the mode of existing, or the fact of being. Over the centuries inquiries into the nature of life have crossed the boundaries from philosophy to biology, forensic medicine, anthropology, etc., in creative as well as scientific literature. (Random House Unabridged Dictionary, 2d ed; Dr. James H. Cassedy, NLM History of Medicine Division)Brain Stem: The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.Brain Mapping: Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.Attitude to Death: Conceptual response of the person to the various aspects of death, which are based on individual psychosocial and cultural experience.Jurisprudence: The science or philosophy of law. Also, the application of the principles of law and justice to health and medicine.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Ethics, Medical: The principles of professional conduct concerning the rights and duties of the physician, relations with patients and fellow practitioners, as well as actions of the physician in patient care and interpersonal relations with patient families.Life Support Care: Care provided patients requiring extraordinary therapeutic measures in order to sustain and prolong life.Caloric Tests: Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.Beginning of Human Life: The point at which religious ensoulment or PERSONHOOD is considered to begin.Withholding Treatment: Withholding or withdrawal of a particular treatment or treatments, often (but not necessarily) life-prolonging treatment, from a patient or from a research subject as part of a research protocol. The concept is differentiated from REFUSAL TO TREAT, where the emphasis is on the health professional's or health facility's refusal to treat a patient or group of patients when the patient or the patient's representative requests treatment. Withholding of life-prolonging treatment is usually indexed only with EUTHANASIA, PASSIVE, unless the distinction between withholding and withdrawing treatment, or the issue of withholding palliative rather than curative treatment, is discussed.Electroencephalography: Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.Third-Party Consent: Informed consent given by someone other than the patient or research subject.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Delayed Graft Function: General dysfunction of an organ occurring immediately following its transplantation. The term most frequently refers to renal dysfunction following KIDNEY TRANSPLANTATION.Oximes: Compounds that contain the radical R2C=N.OH derived from condensation of ALDEHYDES or KETONES with HYDROXYLAMINE. Members of this group are CHOLINESTERASE REACTIVATORS.Mevinphos: An organophosphate cholinesterase inhibitor that is used as an insecticide.Brain Edema: Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6)Philosophy, MedicalOrgan Preservation: The process by which organs are kept viable outside of the organism from which they were removed (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.Electronic Mail: Messages between computer users via COMPUTER COMMUNICATION NETWORKS. This feature duplicates most of the features of paper mail, such as forwarding, multiple copies, and attachments of images and other file types, but with a speed advantage. The term also refers to an individual message sent in this way.Food Dispensers, Automatic: Mechanical food dispensing machines.Editorial Policies: The guidelines and policy statements set forth by the editor(s) or editorial board of a publication.Authorship: The profession of writing.

Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.Publishing: "The business or profession of the commercial production and issuance of literature" (Webster's 3d). It includes the publisher, publication processes, editing and editors. Production may be by conventional printing methods or by electronic publishing.Ethicists: Persons trained in philosophical or theological ethics who work in clinical, research, public policy, or other settings where they bring their expertise to bear on the analysis of ethical dilemmas in policies or cases. (Bioethics Thesaurus)Ethics Consultation: Services provided by an individual ethicist (ETHICISTS) or an ethics team or committee (ETHICS COMMITTEES, CLINICAL) to address the ethical issues involved in a specific clinical case. The central purpose is to improve the process and outcomes of patients' care by helping to identify, analyze, and resolve ethical problems.Ethical Analysis: The use of systematic methods of ethical examination, such as CASUISTRY or ETHICAL THEORY, in reasoning about moral problems.Vitamin A: Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of CAROTENOIDS found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products.Ascorbic Acid: A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.Vitamins: Organic substances that are required in small amounts for maintenance and growth, but which cannot be manufactured by the human body.Vitamin E: A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.Vitamin D: A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.Dietary Supplements: Products in capsule, tablet or liquid form that provide dietary ingredients, and that are intended to be taken by mouth to increase the intake of nutrients. Dietary supplements can include macronutrients, such as proteins, carbohydrates, and fats; and/or MICRONUTRIENTS, such as VITAMINS; MINERALS; and PHYTOCHEMICALS.

The case for a statutory 'definition of death'. (1/411)

Karen Quinlan, the American girl who has lain in deep coma for many months, is still 'alive', that is to say, her heart is still beating and brain death has not occurred. However, several other cases have raised difficult issues about the time of death. Dr Skegg argues that there is a case for a legal definition of death enshrined in statutory form. He suggests that many of the objections to a statutory provision on death are misplaced, and that a statute concerning the occurrence of death could remove all doubts in the minds of both doctors and public as to whether a 'beating heart cadaver' was dead or alive for legal purposes.  (+info)

A matter of life and death: what every anesthesiologist should know about the medical, legal, and ethical aspects of declaring brain death. (2/411)

Accurate criteria for death are increasingly important as it becomes more difficult for the public to distinguish between patients who are still alive from those who, through the aid of medical technology, merely look like they are alive even though they are dead. Patients and their families need to know that a clear line can be drawn between life and death, and that patients who are alive will not be unintentionally treated as though they are dead. For the public to trust the pronouncements of medical doctors as to whether a patient is dead or alive, the criteria must be unambiguous, understandable, and infallible. It is equally important to physicians that accurate, infallible criteria define death. Physicians need to know that a clear line can be drawn between life and death so that patients who are dead are not treated as though they are alive. Such criteria enable us to terminate expensive medical care to corpses. Clear criteria for death also allow us to ethically request the gift of vital organs. Clear, infallible criteria allow us to assure families and society that one living person will not be intentionally or unintentionally killed for the sake of another. The pressure of organ scarcity must not lead physicians to allow the criteria for life and death to become blurred because of the irreparable harm this would cause to the patient-physician relationship and the devastating impact it could have on organ transplantation. As the cases presented here illustrate, anesthesiologists have an important responsibility in the process of assuring that some living patients are not sacrificed to benefit others. Criteria for declaring death should be familiar to every anesthesiologist participating in organ retrieval. Before accepting the responsibility of maintaining a donor for vital organ collection, the anesthesiologist should review data supplied in the chart supporting the diagnosis of brain death and seriously question inconsistencies and inadequate testing conditions. Knowledge of brain death criteria and proper application of these criteria could have changed the course of each of the cases presented.  (+info)

Donor catecholamine use reduces acute allograft rejection and improves graft survival after cadaveric renal transplantation. (3/411)

BACKGROUND: Epidemiological data implicate that renal transplants from living unrelated donors result in superior survival rates as compared with cadaveric grafts, despite a higher degree of human lymphocyte antigen (HLA) mismatching. We undertook a center-based case control study to identify donor-specific determinants affecting early outcome in cadaveric transplantation. METHODS: The study database consisted of 152 consecutive cadaveric renal transplants performed at our center between June 1989 and September 1998. Of these, 24 patients received a retransplant. Donor kidneys were allocated on the basis of prospective HLA matching according to the Eurotransplant rules of organ sharing. Immunosuppressive therapy consisted of a cyclosporine-based triple-drug regimen. In 67 recipients, at least one acute rejection episode occurred during the first month after transplantation. They were taken as cases, and the remaining 85 patients were the controls. Stepwise logistic regression was done on donor-specific explanatory variables obtained from standardized Eurotransplant Necrokidney reports. In a secondary evaluation, the impact on graft survival in long-term follow-up was further measured by applying a Cox regression model. The mean follow-up of all transplant recipients was 3.8 years (SD 2.7 years). RESULTS: Donor age [odds ratio (OR) 1.05; 95% CI, 1.02 to 1.08], traumatic brain injury as cause of death (OR 2.75; 95% CI, 1.16 to 6. 52), and mismatch on HLA-DR (OR 3.0; 95% CI, 1.47 to 6.12) were associated with an increased risk of acute rejection, whereas donor use of dopamine (OR 0.22; 95% CI, 0.09 to 0.51) and/or noradrenaline (OR 0.24; 95% CI, 0.10 to 0.60) independently resulted in a significant beneficial effect. In the multivariate Cox regression analysis, both donor treatment with dopamine (HR 0.44; 95% CI, 0.22 to 0.84) and noradrenaline (HR 0.30; 95% CI, 0.10 to 0.87) remained a significant predictor of superior graft survival in long-term follow-up. CONCLUSIONS: Our data strongly suggest that the use of catecholamines in postmortal organ donors during intensive care results in immunomodulating effects and improves graft survival in long-term follow-up. These findings may at least partially be explained by down-regulating effects of adrenergic substances on the expression of adhesion molecules (VCAM, E-selectin) in the vessel walls of the graft.  (+info)

N18 in median somatosensory evoked potentials: a new indicator of medullary function useful for the diagnosis of brain death. (4/411)

OBJECTIVES: To record N18 in median somatosensory evoked potentials (SEPs) for deeply comatose or brain dead patients and to demonstrate the usefulness of N18 for the diagnosis of brain death in comparison with auditory brain stem responses (ABRs) and P13/14 in median SEPs, which have been conventionally used as complementary tests for the diagnosis of brain death. METHODS: Subjects were 19 deeply comatose or brain dead patients. Thirteen recordings were performed in deeply comatose but not brain dead conditions, and 12 recordings were performed in brain death. N18 was evaluated in the CPi-C2S lead (or other scalp-C2S leads) to obtain a flat baseline. RESULTS: N18 was preserved in 12 of 13 non-brain dead comatose recordings whereas it was completely lost for all of the 12 brain death recordings. P13/14 in median SEPs was preserved for all the comatose recordings, whereas apparent P13/14-like potentials, usually of low amplitude, were seen in nine of 12 brain death recordings-that is, frequent false positives. The ABRs already showed features which were characteristic for brain death (loss of components other than wave 1 or small wave 2) for four comatose recordings, in three of which N18 was preserved. The last result not only corresponds with the fact that ABRs can evaluate pontine and midbrain functions and not medullary function, but further supports the medullary origin of N18. In the four patients followed up for the course of progression from coma to brain death, N18s preserved in normal size during the comatose state were completely lost after brain death was established. CONCLUSIONS: The N18 potential is generated by the cuneate nucleus in the medulla oblongata in the preceding studies. N18 is suggested to be a promising tool for the diagnosis of brain death because there were no false positives and rare false negatives in the present series for detecting the remaining brain stem function.  (+info)

The ambiguity about death in Japan: an ethical implication for organ procurement. (5/411)

In the latter half of the twentieth century, developed countries of the world have made tremendous strides in organ donation and transplantation. However, in this area of medicine, Japan has been slow to follow. Japanese ethics, deeply rooted in religion and tradition, have affected their outlook on life and death. Because the Japanese have only recently started to acknowledge the concept of brain death, transplantation of major organs has been hindered in that country. Currently, there is a dual definition of death in Japan, intended to satisfy both sides of the issue. This interesting paradox, which still stands to be fully resolved, illustrates the contentious conflict between medical ethics and medical progress in Japan.  (+info)

Implications of ischemic penumbra for the diagnosis of brain death. (6/411)

The data reviewed here suggest the possibility that a global reduction of blood supply to the whole brain or solely to the infratentorial structures down to the range of ischemic penumbra for several hours or a few days may lead to misdiagnosis of irreversible brain or brain stem damage in a subset of deeply comatose patients with cephalic areflexia. The following proposals are advanced: 1) the lack of any set of clinically detectable brain functions does not provide a safe diagnosis of brain or brain stem death; 2) apnea testing may induce irreversible brain damage and should be abandoned; 3) moderate hypothermia, antipyresis, prevention of arterial hypotension, and occasionally intra-arterial thrombolysis may contribute to good recovery of a possibly large subset of cases of brain injury currently regarded as irreversible; 4) confirmatory tests for brain death should not replace or delay the administration of potentially effective therapeutic measures; 5) in order to validate confirmatory tests, further research is needed to relate their results to specific levels of blood supply to the brain. The current criteria for the diagnosis of brain death should be revised.  (+info)

Brain death diagnosis in misleading conditions. (7/411)

The necessity of defining brain death (BD) arose from technological development in medical science. The definition of this concept had practical consequences and opened the way to organ donation from BD patients. Nowadays, the imbalance between the number of organs available for transplantation and the size of the demand is becoming critical. In most laboratories, a BD diagnosis is made according to precise criteria and in a well-defined process. BD diagnosis should be improved, not only to assure the safety and to preserve the human dignity of the patient, but also in order to increase the rate of organ donation. By analysing some epidemiological parameters in BD diagnosis and organ donation, it appears that BD diagnoses can be made more often and more rapidly if one has a reliable, accurate, and safe confirmatory test, especially under misleading conditions (hypothermia, drugs, metabolic disturbances). In our experience, the use of multimodality evoked potentials (MEPs) to confirm a BD diagnosis has many advantages: MEPs can be rapidly performed at the patient's bedside, assess the brain stem as well as the cerebral cortex, and are innocuous for the patient. Moreover, their insensitivity to the aforementioned misleading factors is sufficient to distinguish BD from clinical and EEG states that mimic BD. They give an immediate diagnosis, and no delay is required in BD confirmation if there is sufficient cause to account for BD. MEPs are a safe, accurate, and reliable tool for confirming a BD diagnosis, and their use can improve the organ donation rate while preserving the safety of the patient.  (+info)

Re-examining death: against a higher brain criterion. (8/411)

While there is increasing pressure on scarce health care resources, advances in medical science have blurred the boundary between life and death. Individuals can survive for decades without consciousness and individuals whose whole brains are dead can be supported for extended periods. One suggested response is to redefine death, justifying a higher brain criterion for death. This argument fails because it conflates two distinct notions about the demise of human beings--the one, biological and the other, ontological. Death is a biological phenomenon. This view entails the rejection of a higher brain criterion of death. Moreover, I claim that the justification of the whole brain (or brain stem) criterion of death is also cast into doubt by these advances in medical science. I proceed to argue that there is no need to redefine death in order to identify which treatments ought to be provided for the permanently and irreversibly unconscious. There are already clear treatment guidelines.  (+info)

The shortage of suitable donor hearts for cardiac transplantation is exacerbated by the exclusion of those that exhibit contractile malfunction during the period after brain death but before excision. We have replicated the phenomenon of brain death-induced hemodynamic deterioration in the rat in vivo. After 60 minutes of brain death (defined as the absence of electrical activity in the brain), a variety of indicators of cardiac contractile function fell by approximately 50% (thus cardiac index fell from 21 +/- 2 to 11 +/- 1 ml/min per 100 g body weight). However, once excised and perfused ex vivo, the hearts recovered a level of cardiac function that was identical to that from control animals that had not been subjected to brain death. Similarly, when hearts were excised, stored (6 hours at 4 degrees C), and reperfused ex vivo with blood, they also recovered a functional capability identical to that of normal hearts from animals that had not been subjected to brain death. Our results question ...
INTRODUCTION: Conventional apnea testing in patients with severe hypoxemia or hemodynamic instability with removal from the ventilator support is unsafe. We describe an alternative approach to apnea testing, which may be used in patients with hypoxia unable to undergo conventional apnea testing. METHODS: Case Report. A 42-year-old man had a severe traumatic brain injury resulting in diffuse cerebral edema and subarachnoid hemorrhage with herniation. His presentation was complicated by hypoxic respiratory failure from pulmonary contusions and hemorrhagic shock. On hospital day 2, the patient lost brain stem reflexes. Brain death testing with conventional apnea testing was attempted but aborted due to hypoxia. RESULTS: A modified apnea test was applied, which had been approved by appropriate hospital committees including critical care operations, ethics, and the brain death protocol council. Minute ventilation was gradually decreased by | /=50% to attain a PaCo2 level | /=20 mm Hg above baseline. The

BACKGROUND: Consistent difference in graft survival after renal transplantation has been shown when cadaveric transplants are compared to the living related donor situation, in favor of the latter. Recently, evidence has been put forward that brain death has significant effects on the donor organ quality. In this study, we aimed to assess the relation between brain death-induced hemodynamic instability in combination with the duration of brain death on the function and immunogenicity status of potential donor kidneys. METHODS: In Wistar rats, short-term (1 hour) or long-term (6 hours) brain death in the presence or absence of hemodynamic stability was applied. Sham-operated rats served as controls (1 hour and 6 hours). Organ function was studied by monitoring serum creatinine, lactate dehydrogenase (LDH), lactate, and total protein content. Expression of cell adhesion molecules [intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1)] and the influx of leukocytes in the
Almost fifty years since the concept of brain death was first introduced, some individuals and whole nations still struggle with its concept and justification. Many controversies continue to surround brain death, although there is broad consensus that human death is ultimately death of the brain. This crucially involves the irreversible loss of the capacity for consciousness combined with the irreversible loss of the capacity to breathe since, taken together, these elements represent the most basic manner in which a human being can interact with their environment. Confusingly brain death is defined in two different ways based on whole brain and brainstem formulations, although the clinical determination of both is identical. It is not widely appreciated that death is a process, and this leads to misunderstanding by both the public and professionals; reports of brain dead patients being kept alive on a ventilator are familiar. Pragmatically, once a threshold of irreversibility in the dying
In view of the increasing need for organ transplants( possibly because of the greater ability of the surgeons and physicians to both execute the transplant, prevent a rejection, and/or diagnose the need to transplant) how could one minimize the Type I statistical error (the possibility that while the patient is not brain dead he is diagnosed as such) when testing for brain death?. It is a waste of resources to wait for metabolic death clinging to a life that cannot be saved thence omitting the duty to save people.. Nonetheless the duty to omit killing people actively/intently is even greater. This is exactly what we are doing when we remove the life support of someone in a chronic vegetative state( we will not go to jail only because at that time as medical standards mandate we wrongly assumed/believed they were brain dead, i.e We acted according to the medical standards but nonetheless came to a wrong conclusion/diagnosis).. Being a layman( I studied(partialy, uncomplete course) medicine ...
While the concept of brain death is widely accepted, no universal criteria exist for its determination. This study compared guidelines from 80 countries finding that all standards specified exclusion of confounders, irreversible coma, absent motor response, and lack of brain-stem reflexes (see Wijdicks, "The Diagnosis of Brain Death" for more information). The majority of countries had medical practice standards (88%), legal standards (69%), utilized some form of apnea testing (59%), and required more than one physicians declaration (50%). Specifics varied widely on the qualifications of the physician, methods of apnea testing, and observation time before pronouncement of death. Regional differences were also noted, such as mandatory laboratory tests in Europe and Asia. Within the United States, brain death determination has been left to each state to decide (44 states and the District of Columbia have guidelines) whereas most African countries do not. Even if guidelines are not standardized, ...

ANOTHER BRAIN DEATH MISDIAGNOSIS: A 19 year-old woman in Denmark was pronounced brain dead and her parents consented to having her organs donated. The respirator was removed. She didnt die. She is now undergoing rehab and may make a full recovery.. Think this is a one-off? Its not, as I explore in my book, The Law of Life & Death (Harvard 2011) [shameless plug, I know, but its relevant!]. As with the vegetative state, misdiagnosis is more common than the medical community admits-exactly how common is not known. There is far more about the human brain that medical science just does not presently know. For this reason, after researching my book, I am not an organ donor.. ...
In an era where we are becoming more reliant on vulnerable kidneys for transplantation from older donors, there is an urgent need to understand how brain death leads to kidney dysfunction and, hence, how this can be prevented. Using a rodent model of hemorrhagic stroke and next-generation proteomic and metabolomic technologies, we aimed to delineate which key cellular processes are perturbed in the kidney after brain death. Pathway analysis of the proteomic signature of kidneys from brain-dead donors revealed large-scale changes in mitochondrial proteins that were associated with altered mitochondrial activity and morphological evidence of mitochondrial injury. We identified an increase in a number of glycolytic proteins and lactate production, suggesting a shift toward anaerobic metabolism. Higher amounts of succinate were found in the brain death group, in conjunction with increased markers of oxidative stress. We characterized the responsiveness of hypoxia inducible factors and found this correlated

Deceased donor (brain dead, cadaveric) transplant:. This kind of transplant involves taking liver from a person who is brain dead. The persons family must first give consent if organs are to be used for transplantation. This type of transplant requires waiting on a list until a suitable liver is available.. Brain death is sudden death following a road traffic accident or a brain haemorrhage, with irreversible brain damage that is not compatible with life. Brain dead patients may be artificially maintained on a ventilator and supportive medicines for a short duration, and may be able to donate their livers for transplantation, if their family so desires.. Living donor transplant:. This type of transplant occurs when a living person wishes to donate his liver to someone in need. Living donors are usually family members or spouses. All living donors must meet basic medical criteria and undergo a very thorough medical evaluation before being accepted as a suitable donor.. Human organ transplant act ...
Brain death as the modern medical criterion of death while a welcoming development for the twin purposes of saving medical cost and serving the demand for organ procurement is still a controversial subject in the field of Bioethics. The reason is that its scientific credibility in terms of conclusiveness of the termination of life of the whole body system is far from settled. Similarly, its compatibility with Islamic notion of death and its unique metaphysical criterion of the separation of the soul from human body is a debatable topic among the Muslim legists. In the Muslim debate what concerns us is the question of equating brain death to legal death. The most central issue during the juristic discourse was as to whether brain death is a definitive indicator that the soul has left the body. The answer was divergent but with minimum discourse on both theological and scientific dimensions of the issue. Accordingly, this paper argues that interrogating the issue from scientific dimension would ...
Brain Dead 13 is an Interactive movie game produced by ReadySoft that was released for MS-DOS in 1995 and later ported to consoles in 1996. Unlike Dragons Lair and Space Ace, which began as laserdiscs, it was released for PCs and game consoles only. On October 8, 2010, Brain Dead 13 was ported to the iPhone, iPad, and iPod Touch via the App Store, and later upgraded to Version 1.1 on December 1, which added support for iOS 3.0 and 4.2 and fixed various bugs. Lance, a young computer expert, is called to fix a computer at a scary, dilapidated castle. After repairing a large super-computer, Lance learns that his client, the disembodied brain of Dr. Nero Neurosis, has a diabolical plan to take over the world. He quickly finds himself in trouble, being chased around the castle by Dr. Nero Neurosiss psychotic servant Fritz. The player must guide Lance through the castle in order to defeat Dr. Neurosis and escape with his life. The game consists entirely of quick time events. During gameplay ...

The Organ Donation Taskforce recommended that potential organ donors should be identified in the ED and embedded specialist nurses employed to facilitate organ donation from these donors.1. The process of organ donation has traditionally been seen as the remit of the critical care complex and neurosurgical intensive care unit as the majority of organs were donated by patients deemed brainstem dead on formal neurological testing (heart beating donors now classified as donor after brain death; DBD). However, the use of kidneys from non-heart-beating donors (now classified as donor after cardiac death; DCD) has increased from 3% in 2000 to 34% by September 2010.7. Moreover, recent research suggests that recipient outcome after transplantation of kidneys from DCD is good compared with kidneys donated by DBD, although further studies are indicated.8 9. To date, no formal brainstem testing of potential donors is undertaken in our ED, mainly due to the fact that many intubated ED patients have been ...
Year on year with improvement in road safety and improvement in neurosurgery the number of ideal young brain dead donors have been declining whilst the number of more marginal donors have been increasing. The consequence of this is the number of heart transplants being performed have steadily declined.. At present there are 600 hearts from brain dead donors offered for transplant every year in the United Kingdom (UK). Of these 200 have anatomical reasons why they cannot be used for transplant such as ischaemic heart disease. 100 are transplanted and the remaining 300 hearts are judged to have inferior function which probably occurs as a direct result of brain death (Dark).. Ex vivo rig testing has been developed for lungs that were judged unsuitable for transplantation. As a result several donor lungs have been improved by warm perfusion on the rig to the extent that they became suitable for transplantation and so national lung transplant rates are increasing (Dark). The aim would be to ...
Usher (Alberto E. Rodriguez/Getty Images)Ushers in the headlines again, but this time not for his messy divorce with Tameka Foster. Hes actually helping Foster, whose 11-year-old son Kyle (called Kile by some reports) was in an accident on Atlantas Lake Lanier at about 3:25 p.m. ET Friday that left him brain dead. Ushers stepson was one of two kids sitting in an inner tube being pulled by a boat that were hit by family friend Jeffrey S. Hubbard, 38, on a Jet Ski, according to MTV News. After being struck in the head and knocked unconscious, Glover was pulled from the water by a bystander. Both victims were flown to Childrens Healthcare of Atlanta at Egleston, where, according to TMZ, the boy did not have any brain activity when he arrived at the hospital and is still on life support. Brain death, USA Today reports, occurs when all brain activity has stopped permanently, the person is in a coma, and the person is no longer breathing. The girls injuries are "serious." Alcohol was not a ...
George Pickerings heart was certainly turned to his son. May all fathers defend their children like this man did. I doubt he ever intended to use that gun against anyone and gave it to his other son long before the standoff ended, but he gained enough time to save his sons life. May God use his sacrifice to save many others. There isnt a single person declared "brain dead" who isnt alive. Jahi is alive even though California has considered her dead for TWO YEARS! Who are they kidding ...
Brain Death Committee performed the first brain death exam and confirmatory apnea test. The girl was brain dead. The family was consoled. What brain death really means (the brain is dead, there is no longer any blood flow to the brain, she can never get better because brain death is different from coma) was compassionately explained to the family.. Bhavna Jagwani and Dilip Jain of MFJCF then joined Kamlesh Verma, the SMS Transplant Coordinator, to speak with the family about the notion of organ donation. As is usual with such sensitive and intense discussions, the decision to consent to organ donation by the entire family took several hours. But they said yes. They said "yes we consent to donating life saving organs from our deceased daughter in order to save the lives of others" even at a time of extreme emotional duress. This decision continuously impresses on me the miraculous kindness and Daan of the Indian people and donor families all over the world.. We started organizing the immunologic ...
The below are quotes from the article "Are You Sure He is Dead?": Doctors Struggle with Families Lack of Understanding of HOTA featured on 5 May 2019 at with notes on them.. Singaporeans and Permanent Residents aged 21 and above are deemed donors, unless they chose to opt out. It allows for their heart, kidneys, liver and corneas to be harvested for transplantation when they are declared brain dead.. Note 1: If choosing to opting out, use this form: They [i.e. family members] either cannot come to terms with the death of the family member or doubt that their family member is really brain dead.. Note 2: There is no worldwide agreement on what brain death really is, and that being brain dead is being completely dead. This 3 Jan 2019 article shows that the definition of brain death is not even agreed upon ...
Brain-dead donor organ transplantation has been available to children in Japan since the 2010 revision of the Organ Transplant Law. Of the 50-60 brain-dead donor organ transplants performed annually in Japan, however, very few (0-4 per year) are performed in children. Again, while those receiving liver, heart, and kidney transplants are reported to fare better than their counterparts in the rest of the world, organ shortage is becoming a matter of great concern. Very few organs become available from brain-dead donors or are transplanted to adults if made available at all, with some children dying while on the brain-dead organ waiting list. Against this background, living-donor transplants, split-liver transplants, domino transplants, and hepatocyte transplants represent alternative modalities, each of which is shown to be associated with favorable outcomes. Challenges exist, include streamlining the existing framework for promoting organ donation for children and between children.
Unfortunately, the cause of brain death is indeterminant. It can result from a number of actions, including force trauma to the head (but also diseases, which dont really effect zombies). In all of my research (which does expand beyond Wikipedia), I couldnt find the minimum amount of damage necessary to cause brain death, and all of these results were human-based, as zombie research is seriously underfunded ...

A.Not really. Its true that as much as 65 percent of brain death exams are done incorrectly, and many doctors could not list the criteria for brain death correctly. Doctors I talked to said not to worry about patients moving about on the table or their blood pressure or heart rate spiking during harvest. These were just post-death reflexes, not an indication of pain or awareness. And yet the Harvard Criteria, the ur-text of brain death published in 1968, specifically state that there should be no reflexes and no movement. But the bigger problem is that brain death as death per se is a fiction. There is no scientific purpose for brain death. Its a serious, serious kind of coma, but not death. It was made death for practical reasons. The heart of a brain-dead person still beats, and circulates blood to the organs, keeping them fresh for their future owners. And though the 1981 UDDA (Uniform Determination of Death Act) states that the "whole brain" must be dead, the whole brain is rarely tested. ...
Many are calling this Miracle healing the Hand of God. Taylor Hale miraculously recovered from a fatal diagnosis. In the fall of 2011, Taylor fell off the hood of her friends car and hit her head. She then went in to a coma. Doctors said she would never wake up but after prayers from a friend she miraculously woke up. The family of Taylor gathered in her hospital room about four years ago to say goodbye. It was Sept. 17, 2011 - six days after 14-year-old daughter and a friend sat on the hood of a friends car to stop him leaving. He backed up. One girl slid off and was unhurt. Taylor slipped off and hit the pavement.Stacy Henningsen, Taylors mom, said she was diagnosed with a traumatic brain injury. Taylor was then put into a medically induced coma. Taylor remained unresponsive for a week. Then, she suffered a brain hemorrhage and part of her brain sank into her spinal canal - this meant she was brain dead. Doctors told the parents to take her off life support and discuss organ donation. Jeff ...
If you dont remember what Brain Dead 13 was, it was a CD-ROM game from the 1990s not unlike Dragons Lair. It came out for the Playstation, Jaguar, Saturn and 3D0, and involved moving the joystick or buttons in a certain way in each animated scene or face death. The "story" features Lance Galahad, a computer repair-person gets dispatched to fix a supercomputer at a spooky castle. Then of course, stumbles upon an evil plan to take over the world and gets chased by the henchman of Dr. Nero Neurosis, a hook-handed ghoul named Fritz, and tries to avoid being horribly murdered. This really does have some horrifying deaths in it so Im not sure why this was rated "for 6 and up" other than the ESRB must not have actually played this game very thoroughly - they probably saw the cartoony Lance and Fritz and immediately assumed no one would be having their entrails graphically torn out in this game. They assumed wrong - here are 13 of those horrible, horrible deaths. ...

Jahi MacMath, the 13-year-old California girl who was declared brain dead following a tonsillectomy, was moved by ambulance to an undisclosed location on Sunday. Chldrens Hospital Oakland released a statement Sunday evening saying Jahis body was turned over to the coroner who released the body to Jahis mother, Latasha Winkfield. A private ambulance was seen leaving the hospital loading dock just after 8:30 p.m., reports.. Jahis uncle, Omari Shealey, sent out a tweet at 8:27 p.m. that said, "I told you wed do it!!! I love you Jahi and I will come visit you soon baby girl. Your Uncle is a BEAST!!!". CNN reports the body is being flown by private jet to a controversial outpatient brain injury center in New York. The Life & Hope Network, which is run by a former hair stylist, is not licensed to care for a dead person on a ventilator. The centers website states it provides office spaces for brain injury therapy.. "At this time were named as the potential facility that Jahi and her ...

A 14-yr-old girl sustained a severe head injury in a car accident. On the second postadmission day, she was suspected to be brain dead, and an examination for the determination of brain death was performed. During apnea testing the patient was disconnected from the ventilator and an oxygen supply tubing was placed at the connector of the endotracheal tube. Oxygen insufflation at 10 l/min was started. Approximately 1 min later, blood pressure decreased rapidly to 80/40 mmHg, pulse rate decreased to 40 beats/min, and oxygen saturation decreased to 60%. The chest looked hyperinflated. When the oxygen catheter was removed, the chest deflated and massive bloody froth welled up in the endotracheal tube. When reconnected to the ventilator the chest hardly expanded and the patient could be ventilated only by using a bag-valve. Breath sounds were diminished bilaterally and subcutaneous crepitations were palpated over the chest. Chest radiography showed bilateral massive pneumothorax. Chest tubes were ...
Due to the lack of a helicopter service, this is impractical", Dr Hewage noted.. "In such cases, only the cornea of the eye can be donated (as it does not require much of a supply of blood to survive) and the body can be donated to a medical faculty", he added.In the case of deceased donors whose hearts beat, this is because the heart is receiving oxygen. This is because of the presence of a built in or in-built pacemaker according to Dr. Hewage. In people who have suffered head injuries, they may become unconscious or slip into a coma which is a situation where the cerebral functions are impaired and while the reflexes and biological functions are present, they do not respond as they are in a form of sleep.. "In an intensive care unit, if the deceased is on a ventilator, the lung will provide oxygen to the heart and in this manner the heart can survive for three to four days to even up to a week", Dr Hewage explained.. In the event of brain death and brain stem death, while in a coma, organs ...

If PCO2 is ≥ 60 mm Hg or PCO2 increase is ≥ 20 mm Hg over baseline normal PCO2, the apnea test result is positive (it supports the clinical diagnosis of brain death); if PCO2 is , 60 mm Hg or PCO2 increase is , 20 mm Hg over baseline normal PCO2, the result is indeterminate, and an additional confirmatory ...
The so-called Wada transplant, said to be Japans first transplant from a brain-dead donor, was conducted in 1968 by Juro Wada at Sapporo Medical University. The boy who received the donors heart died, and Wada was charged with murder. Questions were raised as to whether the organ donor had really been brain dead, and the case stirred a major controversy over the definition of death. For more than 30 years after that, no transplants from brain-dead donors were performed in Japan ...
Reality: No. No no no no no. NO. Have I said that enough? NO! According to this report, Jahis mothers lawyer Christopher Dolan said it is "the right of a parent to make health care decisions relating to whether or not a ventilator gets removed from their child." With that I fully agree. However, he went on to say that families should be the ones to determine death, and here is where he is venturing into territories where he does not belong. Determining death in some situations is quite simple - if the heart is ripped out of the body, the head has been detached from the body, etc. But it takes a doctor with years of training to diagnose brain death. Who wants families deciding when someone dies? What if a family decides gramps is dead while hes still watching reruns of Matlock and Murder, She Wrote because they want his 1965 Aston Martin DB5? Should they be able to declare him dead? The fact of the matter is this: the family should have full control over their loved ones healthcare decisions ...
Due to a lack of published case reports regarding the somatic support of brain dead pregnant patients, each one adds to the limited knowledge that directs care for this patient population. A young woman experienced a cardiac arrest and was subsequently determined to be approximately 20 weeks pregnant following cardio pulmonary resuscitation. Soon after, she was diagnosed as brain dead, but her family chose to keep her supported in hopes of the delivery of a healthy child. She was transferred to our facility, where she was supported after being diagnosed as brain dead for a total of 90 days and delivered a healthy baby boy at almost 32 weeks gestational age ...

PRESIDENT EMMANUEL MACRON of France caused a stir in October when he bluntly told The Economist that "we are currently experiencing…the brain death of NATO." But the Western alliance has been showing signs of vitality. The most recent evidence comes in a survey just published by Pew Research Centre, a think-tank, covering 16 of NATOs 29 member countries. Taken between May and August last year, the poll shows strong public support for the alliance: the median score for those saying they viewed NATO favourably was 53%, compared with 27% with an unfavourable opinion.. Mr Macron has not been the only NATO leader to question the organisations future. Before becoming Americas president, Donald Trump called NATO "obsolete". In office he has unnerved his peers by disrupting summits, lambasting allies for not paying their "fair share" and casting doubt about the Article 5 commitment to mutual defence, in which an attack on one ally is regarded as an attack on all. To twist allies arms, he even ...
In North America, discussion about brain death has been limited for the most part to a small group of doctors and an even smaller group of lawyers and intellectuals.
In medical school, we learn how to perform the brain death exam, and we learn that a patient who is brain dead is dead. A year and half ago, these accepted medical standards were challenged with the case of Jahi McMath. She was a thirteen year old girl who had complications from surgery, suffered a cardiac arrest, and was declared brain dead by multiple pediatric neurologists. The tragedy of this perioperative pediatric death has not been the focus of media attention, but rather the familys challenge that the patient was not, in fact, dead. The family filed legal action to keep the patient on life support. The court ruled that based on independent neurologic exams, EEG, and perfusion studies (the latter two are not necessary, but are adjuncts), the patient was indeed dead. At this time, the family argued that application of the Uniform Determination of Death Act was a violation of constitutional and privacy rights. There may be some precedent for this; in New Jersey, state law allows religious ...

The ASA physical status classification system is a system for assessing the fitness of patients before surgery. In 1963 the American Society of Anesthesiologists (ASA) adopted the five-category physical status classification system; a sixth category was later added. These are: Healthy person. Mild systemic disease. Severe systemic disease. Severe systemic disease that is a constant threat to life. A moribund person who is not expected to survive without the operation. A declared brain-dead person whose organs are being removed for donor purposes. If the surgery is an emergency, the physical status classification is followed by "E" (for emergency) for example "3E". Class 5 is usually an emergency and is therefore usually "5E". The class "6E" does not exist and is simply recorded as class "6", as all organ retrieval in brain-dead patients is done urgently. The original definition of emergency in 1940, when ASA classification was first designed, was "a surgical procedure which, in the surgeons ...
The mother of a girl at the center of a medical and religious debate over brain death said she does not regret moving from California to New Jersey so her daughter could receive care after being declared dead.
Dr. Mishra many thanks for your enquiry. DCD heart procurement is indeed a very exciting and relatively new approach to increasing the donor pool for heart transplantation. Traditionally DBD donors meet criteria for brainstem death (e.g. absent corneal reflexes, no respiratory effort after sedation wean etc) vs. DCD donors who do not necessarily meet the brainstem death criteria (however, may still have severe irreversible cerebral damage) but do not have any realistic prospect of recovery and are expected to go into cardiac arrest (Category III DCD Maastricht criteria) due to the severity of their disease and remain on plenty of haemodynamic and respiratory support, but their heart (+/- other organs) is intact and is suitable for transplantation. In such cases when the consent is obtained, in a controlled environment (i.e. the ICU/operating theatre depending on local protocol) all support is weaned off which would, in most cases, lead to an agonal phase of circulation (hypotension) and ...
SAN FRANCISCO (AP) - Debate over the definition of "brain-dead" reignited this week when a California family and its lawyer asked a judge to declare that 13-year-old Jahi McMath is alive 10 months after a coroner signed her death certificate.. Attorney Christopher Dolan is seeking the unprecedented ruling, arguing that new tests show Jahi has brain activity. Jahi has been kept on a ventilator and feeding tubes since an operation to treat sleep apnea went awry in December. Three doctors, including one appointed by the judge, declared her brain-dead after finding no neurological activity.. Dolan says researchers at the International Brain Research Foundation found signs of activity in Jahis brain last week after testing at Rutgers University in New Jersey. Researchers, doctors and others remain skeptical of the foundations findings and are calling for other tests from independent organizations.. Q: What is brain death?. A: Brain death is the irreversible loss of all functions of the brain. ...

1) No. The medical field uses two criteria for determining death: cardiorespiratory failure and neurologically determined death. Cardiorespiratory failure is the simplest test, and is applied in the vast majority of cases. However, in the medical field, either criterion is sufficient to determine death. Mechanical ventilation has made it possible to maintain cardiorespiratory functioning despite total brain death, and so, diagnostic tests are used to establish the occurrence of total brain death. Total brain death must be distinguished from other neurological damage that does not constitute brain damage. Nothing less than total brain damage constitutes death under this criterion.. The criterion for determining death at law has not been prescribed legislatively. However, some Ontario statutes adopt, either expressly or implicitly, the criteria used in medical practice. The medical practice of using neurological and cardiorespiratory criteria to diagnose death has been accepted by Canadian courts. ...
Purpose of reviewDespite a significant increase in the utilization of donors after circulatory death (DCD), the number of organs recovered and their function are largely inferior to those from donors after brain death. This review summarizes recent advances in in-situ normothermic regional perfusion
The uncontrolled vasodilation accelerates heat loss and hypothermia. Brainstem death is also associated with an active inflammatory response, with elevated levels of proinflammatory cytokines and upregulation of receptors in target organs. Although this may be due to -associated trauma or critical illness, brainstem death itself may trigger this response. The inflammatory response is maintained or amplified by the physiological changes related to brainstem death [16,17,18]. This affects all organs and is associated with measurable organ damage in the donor, and subsequent poor function and increased risk of graft loss in recipients. Collaboration of all professionals in the field of -donation and transplantation is a must, in order to advance our knowledge and make high quality -transplantation sustainable in the future. Summary box Preservation strategies should maintain viability and allow rapid restoration of function: • Hypothermia, prevention of acidosis and oedema and neutralization of ...
Spain has reached an important global level when it comes to transplants. Most donors in our country are brain death patients. Living donors represent a small percentage, although with a clear tendency to increase in the last years. Nonetheless, this high activity of obtaining organs is still not enough to fully cover the transplant needs of our country. The decrease in mortality due to trauma and cerebrovascular disease, together with the changes in the management of neurological patients in critical stages, are leading to a progressive reduction of potential brain death donors. For this reason, additional organ sources must be considered.. Cardiocirculatory arrest donors (CAD) might make a significant cohort of new potential organs that would allow us to reduce transplantation waiting lists. In some countries like the Netherlands, Belgium and Great Britain,1,2 the number of cadaveric donors have doubled thanks to the introduction of CAD. Thus, in Great Britain CAD have gone from being 3% of ...
Urology has become a very big specialty with a lot of sub-specialties within it. Urology mainly consists of the Genito-Urinary Surgeon who cures renal problems by surgery, and the Nephrologist who treats renal problems with drugs. This differentiation has to be fundamentally understood by the lay public, because there is a mix-up of patients on many occasions and they land up with a wrong consultant for their ailments. Kidney transplantation has itself taken huge strides today as the number of End-Stage Renal Disease (ESRD) patients is increasing by leaps and bounds. It is very simple knowledge that when an organ fails it has to be substituted, wherever a substitute is available, as in the case of kidney, liver, pancreas etc. The huge buckle in this kidney transplantation is due to lack of awareness of Brain-Death and the emotions of the relatives of the Brain-dead patient who is on the ventilator. When once they understand this phenomenon of Brain death, the number of cadaver kidneys will ...
Only ethicist Arthur Caplan has the nerve to say it: Years ago, when he moved from Minnesota to Pennsylvania, he was reapplying for his drivers license, and advised by the clerk: Dont mark that: If you do, they will let you die.. The fact that the governor quickly got a heart/liver transplant made a lot of folks suspicious of the scheme to get more organs: The governor was rich of course and the donor was a black homicide victim. In reality, he got the organs because they fit (you have to use a heart from a donor the same size as you are, although livers can be divided up). But the idea that "they might let you die" lurked below the surface. Indeed, when we would air flight our brain damaged rednecks to Pittsburgh "for higher care", the ambulance crews would joke it was a "Body run": I.e. not to benefit the patient, but so the corpse would be closer to the transplant team.. The brain death criteria is strict (but not always followed, alas, although few talk about that either). As one ethicist ...
Apollo Hospitals, Chennai harvested 23 different organs from these five donors and conducted 10 transplants in a day at the flagship Hospital on Greams Road on May 6, 2015. A case of extreme gesture of kindness displayed by five strong families who came forward to donate the organs of their loved ones, incidentally on the same evening, enabled this feat to give a fresh lease of life to 23 people. From five brain dead donors - 4 kidneys, 1 heart and 5 livers were harvested at Apollo Hospitals,
Organ donation is controversial because vital organs can be removed from a patient before his or her life has ended thus disrespecting the dignity of human life. The controversy currently hinges on a disagreement on what method is appropriate to determine final death.. There are two ways a patient can be declared dead: cardiac arrest or brain death. Cardiac Arrest: The controversy surrounding this method is that in order for vital organs (lungs, heart, liver, both kidneys, pancreas etc.) to be donated, organs must be collected between 90 seconds and two minutes following the cardiac arrest. A protocol called Donation After Cardiac Death (DCD) was developed to teach physicians how to swiftly determine death and collect vital organs before they expire. Donation after Cardiac Death (DCD) is a protocol used to obtain organs when the criterion for declaring brain death is not present.. The problem: Patients can medically recover (be brought back to life) for up to about 5 minutes after cardiac ...

HealthDay News) -- By improving the way certain donated organs are handled before a transplant, more organs could end up being used, new research suggests.. The concern centers on organs donated following circulatory death (DCD). That means a patients heart, breathing and circulation stop functioning. Most donated organs come from people who are brain dead, but their circulation is continued with machines.. Organs donated by DCD must undergo a controlled cooling process (called cold ischemia) after the organ loses its original blood supply. The organ is then re-warmed when blood supply is renewed at the time of transplant.. This process leads to a heightened risk for tissue damage.. But a team led by Dr. John Gill of the University of British Columbia and Vancouvers Providence Health Care found that by limiting the cooling process to a period of no more than 12 hours, DCD kidney donations were just as likely to survive once transplanted than those donated following brain death.. In a news ...

The diagnosis of brain death following total and irreversible cessation of all cerebral functions is based on anthropological assumptions and conventions as well as on the exact medical diagnosis of total loss of brain function. The question whether individual life ends after cerebral function is irreversibly lost cannot be answered by medical definition alone. Clear and unrefutable legal definitions of death and the cessation of the rights of the individual must be provided before organs may be harvested from brain dead individuals. Acceptance of these definitions by the general population is of paramount importance for the practice of organ donation. In the first part of this article, the legal definition of death and the provisions of the German transplantation law are critically reviewed. The legal statements deal with the question of the definition of death and how death can be detected. The provisions of the German transplantation law are referenced with special attention to the provision ...

Only 5% (one out of 20!) of all registered organ & tissue donors will likely be able to donate organs. Its a complicated issue - but basically, if a potential donor dies a "cardiac" death (e.g., heart attack, most disease processes, old age) the organs do not stay viable enough for transplant. Tissues are still OK (eyes, skin, blood vessels), but not organs (heart, kindey, lungs, liver, etc). Only the 5% (or so) of people who die "brain death" - stroke, aneurysm, some type of trauma that causes brain death, but where a persons organs can be sustained on a ventilator - can actually donate those organs. So its critical that everybody who possibly can sign up as an organ-donor actually does sign up - just to make that 5% as big as possible ...
Dear Anonymous. I would not personally accept a transplant of an organ without which the body could not function.. There is an excellent article on the Catholic teaching on organ donation which you might want to read.. It states in part:. It is not true that the international scientific community is unanimously favorable to the current "neurological" criteria which results in a conclusion of "brain death." In fact, this recent concept was introduced to make possible the removal of organs from those finding themselves in a cerebral coma. But, as we shall cite, many scientists and professors have published their research and reported their results in authoritative scientific and medical journals. In these reports, they have stated their disapproval of the "brain death" concept because it does not coincide with total and irreversible cessation of brain activity; for these workers, it is not scientific and is not verifiable as true death. [See "Brain Death Is False," TheAngelus, March, 2000, ...

Background: Donation after circulatory death (DCD) donors , 55 years are usually not considered suitable for liver transplantation (LT). At our institute, age is not an absolute exclusion criterion to refuse DCD liver grafts. We retrospectively compared the transplant outcome of patients receiving older DCD liver grafts to the younger ones. Methods: 70 DCD liver transplants have been performed from 2003 to 2012, which includes 32 liver grafts from younger donors ,55y (group A), 20 between 56 and 69 years (group B), and 18 from older donors ≥70 years (group C). The three groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first ...

Her parents argued that the Christian faith defines death as when the heart stops, and that doctors should take peoples beliefs into consideration before declaring them dead.. According to The Canadian Press, Ontario Superior Court Justice Lucille Shaw ruled that individual values cannot interfere with medical findings on June 26, 2018. In a report from the Canadian Press on October 9, 2019, it was announced that the court declined McKittys familys appeal to rule on whether someones religious beliefs should be considered in the criteria used to determine someones death.. A unanimous decision concluded that "while death is not defined in law federally or provincially in Ontario, common law considers someone dead when there is irreversible cessation of either cardiorespiratory or brain function.". Similar questions will likely occur in the future, said the ruling, laying out guidelines for the assessment of those arguments, adding that the lower court judge "made several errors.". ...
Looking for online definition of apnea test in the Medical Dictionary? apnea test explanation free. What is apnea test? Meaning of apnea test medical term. What does apnea test mean?
The diagnosis of brain death (BD) is based on clinical criteria including deep coma, brain stem areflexia and apnoea. Depending on different local guidelines, confirmatory technical tests are sometimes mandatory.1 Since the 1990s, transcranial Doppler sonography (TCD) has found its place in these circumstances and fulfils most of the criteria of an ideal test in confirming BD. To confirm intracranial circulatory arrest (CA) with Doppler sonography, typical flow patterns must be recorded in bilateral intracranial and extracranial brain-supplying arteries.2 A completely absent intracranial flow signal is not a reliable sign to determine CA because this can be due to transmission problems. Inadequate ultrasound penetration of the temporal bone is a major drawback of this technique, making definitive assessment of intracranial flow patterns impossible. Stabilised microbubble ultrasonic contrast agents (UCA) are routinely used in neurological clinical routine when intracranial insonation is ...
Failure of health care professionals to identify potential donors is considered an important contributing factor to the shortage of deceased organs,11 15 and accounted for 14% of our potential organ donor loss. Education directed at doctors and nurses to increase their awareness of possible organ donors is crucial to the success of an organ donation programme. Identification of a possible deceased organ donor should be inherently linked to the act of referral to a key donation person/team for activation of the deceased donation process.11 Similar to other hospitals in Hong Kong, all possible brain-dead donors at our centre, regardless of apparent medical contra-indications, are referred to our ODC as soon as they are identified. Referral usually occurs early when the clinical condition reveals death to be imminent or that further treatment will be futile. The possible deceased organ donors can then be assessed and managed by the ODC immediately as all the ODCs in our territory have a centralised ...
MAIN OUTCOME MEASURES. Knowledge on various aspects of organ donation was assessed, and students self-evaluated competence and confidence about counselling for organ donation was evaluated. Factors influencing attitudes and actions were determined. RESULTS. The response rate was 94% (655/694). A majority (85%) had a positive attitude, but only a small proportion (23%) had signed the organ donation card. Inconvenience and lack of knowledge about organ donor registration, and concerns about premature termination of medical treatment accounted for such discrepancies. Socio-cultural factors such as the traditional Chinese belief in preservation of an intact body after death, unease discussing death-related issues, and family objections to organ donation were significantly associated with a negative attitude. Knowledge and action increased with medical education yet only a small proportion of medical students felt competent and confident in counselling patients on organ donation ...

Federal regulations require that Organ Procurement Organizations (OPOs) be notified of the impending death of potential donors [10]. The timing of this notification can be self-evident: the patient on life support and vasopressor agents that maintain the blood pressure artificially, whose end is inevitable, no matter the intervention. But sometimes, the end is contingent upon decisions about the withholding or withdrawal of life support.. Case in point: what to do about those who have sustained a severe brain injury. Totally dependent upon ventilator support for at least airway protection if not ventilation as well, they can quickly become the imminently dying if a decision is made to withdraw the ventilator. And once such decisions are contemplated, regulations would have it that the OPO be notified about the possibility of what is commonly and euphemistically termed a potential organ harvest.. My problem as an OPO board member was that, too often, patients like these were viewed as if they ...

  • A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer's disease, stroke, migraine, multiple sclerosis, brain injury, epilepsy and Parkinson's disease. (
  • Because of Jahi's severe blood loss and heart attack, she was deprived of oxygen to her brain and suffered a catastrophic anoxic brain injury, which led to swelling of her brain. (
  • While the study offers no immediate therapeutic benefits for humans, it creates a new research platform that may ultimately help doctors find ways to revive brain function in stroke patients or to test new treatments for restoring brain cells damaged by injury, the authors said. (
  • Recovery is more rare in these cases, but a lot depends upon the amount and type of injury that has been done to the brain. (
  • ILBF can be caused by brain ischemia or anoxia or by any other type of brain disease or injury leading to an elevation of the intracranial pressure above the blood pressure and thereby to an arrest of the cerebral circulation. (

  • While reperfusion may be essential to protecting as much brain tissue as possible, it may also lead to reperfusion injury. (
  • Brain death should not be confused with coma. (
  • While a person in a coma is unconscious, parts of their brain are still functioning, and there is a possibility that their condition may improve. (
  • First, the media commonly confuse people about brain death and coma. (
  • They mix it up with coma (being unconscious but with the possibility of recovery) and permanent vegetative state (loss of consciousness but not death). (
  • They mix it up with things like coma, where people can get better-but that is not brain death. (
  • The Australia and New Zealand Intensive Care Society (ANZICS) states that the "determination of brain death requires that there is unresponsive coma, the absence of brain-stem reflexes and the absence of respiratory centre function, in the clinical setting in which these findings are irreversible. (
  • It is important to distinguish between brain death and states that may be difficult to differentiate from brain death, (such as barbiturate overdose, alcohol intoxication, sedative overdose, hypothermia, hypoglycemia, coma, and chronic vegetative states). (
  • Anahita Meshkin, who has been in a coma for eight years and had been declared brain dead, lies in bed and is hooked up to machines at her care facility in Walnut Creek, Calif., on May 10. (
  • Also last year, Mohammad Meshkin reached out to Dolan about his daughter, Anahita Meshkin, who had been in a coma for eight years before being declared brain-dead. (
  • Unlike a coma, brain death is the loss of all brain function, an irreversible and nationally accepted form of death. (
  • After her heart stopped and she suffered brain damage, Schiavo entered what doctors refer to as a 'persistent vegetative state,' or prolonged coma. (
  • The clinical criteria of brain death (BD), deep coma and absence of brain stem reflexes, may be difficult to evaluate in patients in the intensive care unit (ICU) in the presence of central nervous system (CNS) depressants. (

  • Magnetic resonance imaging (MRI) became available in Malawi in 2009, and we used it to investigate the role of brain swelling in the pathogenesis of fatal cerebral malaria in African children. (
  • Increased brain volume was seen in children who died from cerebral malaria but was uncommon in those who did not die from the disease, a finding that suggests that raised intracranial pressure may contribute to a fatal outcome. (
  • A cerebral aneurysm is a thin or weak spot that can occur on a blood vessel of the brain. (
  • He says that while the cause of some deaths could not be determined with certainty, many appeared to have been the result of high-altitude cerebral oedema. (

  • 1 Many countries require a clinical diagnosis of BD to be confirmed by a demonstration of lack of brain cerebral function or circulation. (
  • In these cases, ancillary tests such as electroencephalography, cerebral angiography, nuclear scan, transcranial Doppler, CTA, and MR imaging/MRA are currently used in adults to pronounce brain death. (
  • Although cerebral angiography is considered the criterion standard, 2 ⇓ - 4 CTA has been accepted as one of the ancillary tests for confirmation of brain death. (
  • Brain ischemia (a.k.a. cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. (
  • This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke. (
  • Focal brain ischemia occurs when a blood clot has occluded a cerebral vessel. (
  • Similar to cerebral hypoxia, severe or prolonged brain ischemia will result in unconsciousness, brain damage or death, mediated by the ischemic cascade. (

  • These findings illustrate why there's a crucial need to standardize approaches for determining brain death," said Gene Sung, MD, MPH, of the University of Southern California in Los Angeles and a member of the American Academy of Neurology, who wrote an editorial regarding the article that is published in Neurology. (
  • Under California law, brain death occurs when there is a total and irreversible cessation of all neurological activity, including the brain stem. (
  • Jahi had been declared dead in December 2013 at age 13 after suffering irreversible brain damage during surgery in California to remove her tonsils. (
  • This could not be more obvious than in the utter confusion on display over the concepts of 'brain death' and 'life support technology' that has resulted in two dead bodies being kept on ventilator support in California and Texas. (
  • Both California and Texas state law realize the reality of what brain death is and what it means. (
  • The findings - published in the journal Science - could pave the way for new therapies to stop the process in its tracks and potentially prevent brain cell death. (
  • The key pathogenetic processes and causes of death are unknown, but a combination of clinical observations and pathological findings suggests that increased brain volume leading to raised intracranial pressure may play a role. (
  • They said the findings may call into question the accuracy of brain-death determinations across institutions. (

  • Practice parameters for determining brain death in adults (summary statement) (1995) The Quality Standards Subcommittee of the American Academy of Neurology. (
  • In 2010, the American Academy of Neurology updated its brain death guidelines, which now call for only one brain death examination. (
  • Dr. David Greer reported in Neurology (Jan 2008) that many highly regarded hospitals in the U.S. routinely diagnose "brain death" without following the guidelines promulgated in 1995 by the American Academy of Neurology (AAN). (
  • After brain death has occurred, it may be possible for the person's organs to be used in transplantations, which can often save the lives of others. (
  • If we wait for a person's heart and lungs to cease functioning (the traditional way of determining death), the organs become unusable for most transplants. (
  • There is no international acceptance about brain death, the only consensus about it is doubt about it.It's a social constract for taking organs. (
  • Uh, that means you might still have a brain functioning when you cut the guy to remove his organs out. (
  • The law and the facts indicated that Dr. Roozrokh … tried to accelerate [Navarro's] death to facilitate the harvesting of his organs," said Chief Deputy Dist. Atty. Stephen Brown. (
  • There is supposed to be strict criteria for brain death, and a strict line between those caring for the patient and those who want the organs. (
  • Since the 1960s, laws on determining death have, therefore, been implemented in all countries with active organ transplantation programs. (
  • This new definition, the irreversible loss of the capacity for consciousness and for spontaneous breathing, and the essentially unchanged 1976 tests held to establish that state, have been adopted as a basis of death certification for organ transplant purposes in subsequent Codes of Practice. (
  • Brain Death is a new, ambitious, and thoroughly researched work that draws heavily upon original research data but also is interspersed throughout with practical information for the practicing neurologist, neurointensivist, neurosurgeon, anesthesiologist, trauma surgeon and organ procurement organizations. (
  • In this course you will learn about the science behind death determination and when it is possible for deceased organ donation take place. (
  • Welcome to the first week of Organ Donation - From Death to Life. (
  • OBJECTIVE: The time preceding brain death is associated with complex dysregulation including autonomic dysfunction that may compromise organ perfusion, thus inducing final organ failure. (
  • Still, the study raises a host of bioethical issues, including questions about the very definition of brain death and potential consequences for protocols related to organ donation. (
  • After a potential liver donor is identified following brain death, the donor undergoes a very careful medical evaluation and review of behavioral risk factors by a medical professional forum, the organ procurement organization (OPO). (
  • Clinically defined, this is not a living brain, but it is a cellularly active brain," study co-author Zvonimir Vrselja, associate researcher in neuroscience. (
  • Once the brain stem has permanently stopped functioning, there's no way of reversing it and the heart will eventually stop beating, even if a ventilator continues to be used. (
  • To save a person's family and friends from unnecessary suffering, once there's clear evidence that brain death has occurred, the person will be disconnected from the ventilator. (
  • Experts say there is an increase in the number of families fighting brain-death diagnoses since an Oakland, Calif., family won the legal right to move their daughter to a facility in New Jersey, where she now resides on a feeding tube and ventilator. (
  • Although brain death is defined by the medical community to mean a total loss of brain function, McMath's family fought to keep her on a ventilator, saying she showed signs of life. (
  • Unlike Jahi, whose heart doctors say would stop beating if she were removed from the machines helping her breath because her brain stem is not functioning, Schiavo maintained signs of limited brain activity and was able to breathe without a ventilator. (
  • To turn off the ventilator for up to 10 minutes as part of the declaration of "brain death" risks further damage and even killing a comatose patient, who might otherwise survive and resume spontaneous breathing if treated properly. (
  • Retired and replaced by "Update: Determining Brain Death in Adults" (June 2010). (
  • Rates of TBI-related deaths per 100,000 population were highest among older adults aged ≥75 years (78.5), those aged 65-74 years (24.7), and individuals 55-64 years (19.1). (

  • In an email, the hospital's attorney G. Patrick Galloway said Gilliam acknowledged an ability to predict how California's high court would interpret the finality of a declaration of brain death under state law. (
  • This is demonstrated by three brain-death evaluations and a ruling by Judge Grillo in December 2013, as well as the declaration of Sanford Schneider M.D., filed in Alameda County Superior Court on Nov. 14, 2016, in support of the motion to unseal reporter's transcripts. (
  • CDC estimated national and state-specific rates and trends for TBI-related deaths (TBI deaths) caused by unintentional falls (fall-related TBI deaths) among U.S. residents during 2008-2017, by selected decedent characteristics. (
  • During 2008-2017, the national age-adjusted rate of fall-related TBI deaths increased by 17%, from 3.86 per 100,000 persons to 4.52 ( Table 1 ), representing 17,408 fall-related TBI deaths in 2017. (
  • Considering only the study endpoint years (2008 and 2017), the number of fall-related TBI deaths increased in 49 of 51 jurisdictions (50 states and DC), and corresponding age-adjusted rates increased in 45 of these 49 jurisdictions (Supplementary Table, ). (
  • Winkfield then took her fight to federal court, but reached a settlement with the hospital in January 2014 to transfer her daughter to a medical facility in New Jersey, where state law contains a religious exemption to brain death. (
  • While lawyers for Children's Hospital have argued that the Winkfield did not subject Jahi to tests accepted by the American Medical Association to determine brain death, the Winkfields' attorney asserts that technology has made traditional tests obsolete. (
  • Winkfield refused to accept the conclusion and took Jahi to New Jersey, which accommodates religions that don't recognize brain death. (
  • In fact, research shows that those who suffer from the most severe brain injuries are statistically more likely to die early -- from a variety of causes. (
  • A total of 25 children (15%) died, 21 of whom (84%) had evidence of severe brain swelling on MRI at admission. (
  • Almost 2 decades ago, NIOSH examined the causes of death among players in the NFL, and noted that there had been four cases of ALS, but little further research was done until recent years, when a series of players were recognized as having severe brain dysfunction and atrophy following multiple concussions. (
  • The core of the text combines the theory and practice of brain death determination, history, and the development of clinical criteria of what brain death is. (
  • Ah, but now the powers that be are trying to change the practice to include "heart beat death" instead of brain death. (
  • Results showed that "adherence to the AAN guidelines varied widely, leading to major differences in practice, which may have consequences for the determination of death and initiation of transplant procedures. (
  • once brain function ceases, the body is no longer able to perform activities that are crucial for our survival, such as breathing, regulation of heartbeat, and swallowing. (
  • Death was said to occur when the heart stopped beating and a person was unresponsive and no longer breathing. (
  • Brain death can occur when the blood and/or oxygen supply to the brain is stopped. (
  • There's a difference between brain death and a vegetative state , which can occur after extensive brain damage. (
  • Death may also occur by autophagocytosis. (
  • Ruptures occur in about 30,000 people in the U.S. each year, and 40 percent of those cases result in death within 24 hours. (

  • Unintentional falls represent the second leading cause of TBI-related death. (
  • There was also wide variation in the specialists allowed to declare brain death. (
  • The lack of oxygen, which occurred as a result of no blood flow, quickly led to the permanent loss of brain stem function. (
  • The brain stem is responsible for regulating most of the body's automatic functions that are essential for life. (
  • And though the term "life" support, perhaps a misnomer, is often applied to this situation, it does not change the fact that a person's life ends when their brain goes forever quiet. (
  • Brain death is the complete loss of brain function (including involuntary activity necessary to sustain life). (
  • With the increasing ability of the medical community to resuscitate people with no respiration, heartbeat, or other external signs of life, the need for another definition of death occurred, raising questions of legal death . (
  • Near-death experiences are triggered during singular life-threatening episodes when the body is injured by a heart attack, shock, or blunt trauma such as an explosion or a fall. (
  • Any close brush with death reminds us of the precariousness and fragility of life and can strip away the layers of psychological suppression that shield us from uncomfortable thoughts of existential oblivion. (
  • I was disappointed to see this newsletter article from the Life Issues Institute and the Terri Schiavo Life & Hope Network titled "The Market for Brain Death. (
  • But both the title and the article go on to suggest that unilateral judgments regarding life-sustaining treatment or aid in dying, "may lie behind what seems to be an increase in the 'brain death' diagnosis. (
  • But five years ago, the RCA published a long position paper ( that, while refraining from taking a definitive stand, unmistakably leaned toward rejecting brain death as a halachically acceptable way to distinguish life and death. (
  • One of the experiences commonly reported near death is seeing one's life suddenly appear before one's eyes in toto. (
  • Revita Life Sciences, ( ) a biotechnology company focused on translational regenerative therapeutic applications, has announced that it is continuing to advance their novel, multi-modality clinical intervention in the state of brain death in humans. (
  • We have proactively continued to advance our multi-modality protocol, as an extended treatment before extubation, in an attempt to reverse the state of brain death" said Mr.Pranjal Agrawal, CEO Revita Life Sciences. (
  • The boundary between life and death is more complex than ever before and it falls to medical professionals to help clarify a situation at an often confusing and emotionally stressful time. (
  • The lectures will cover medical standards at the end of life - from brain death testing, to requesting informed consent from a grieving family. (
  • Terror management theory (TMT) is both a social and evolutionary psychology theory originally proposed by Jeff Greenberg, Sheldon Solomon, and Tom Pyszczynski and codified in their book The Worm at the Core: On the Role of Death in Life (2015). (
  • We succeeded in establishing, for the first time, that, contrary to the doctor's position, parents do have a say in the end of their child's life following a brain death diagnosis. (
  • Despite the acting Public Health Officer's initial refusal to issue a death certificate as Jahi was still on life support, we pressed forward and, under protest, obtained a death certificate. (
  • Although reports of near death experiences around the world share similarities that transcend sex, culture, religion and ethnicity, the controversial subject of near death experiences, and life after death, has previously been met with great skepticism. (
  • And finally, is there more to life after death that extends beyond the resuscitation time frame? (
  • It is important that the doctors should be capable to recognize this difference because in case of brain death the continuation of life support treatment is of no use. (
  • It was found that the "limitation" in the life support system led to the death of about sixty eight children, in ability to provide "cardiopulmonary resuscitation" led to the death of sixty one children. (
  • Besides, certain rise of about eight percent of brain death was experienced as a result of the removal of the life support system during 1997-1998. (
  • The life support facility was limited on the account of bring immediate death. (
  • Our second lesson takes a look at the history of, and the actual mechanism of brain death as well as the story behind the first heart donor. (
  • What's exciting is the emergence of a common mechanism of brain cell death, across a range of different neurodegenerative disorders, activated by the different mis-folded proteins in each disease," said Giovanna Mallucci, who led the research at the University of Leicester's toxicology unit. (
  • The new research builds on a growing body of knowledge of a distinct form of programmed brain cell death dubbed "parthanatos" by the team in earlier work to distinguish it from other types of cell death, such as apoptosis, necrosis, or autophagic death. (
  • The brain stem is the lower part of the brain that's connected to the spinal cord (part of the central nervous system in the spinal column). (
  • The living cells that can cause these movements are not living cells from the brain or brain stem, these cells come from the spinal cord. (
  • The broad term, "stroke" can be divided into three categories: brain ischemia, subarachnoid hemorrhage and intracerebral hemorrhage. (
  • The brain haemorrhage was caused by vascular malfunction, which was diagnosed during the woman's previous pregnancy. (
  • Different triggers spark stroke, injuries, and neurodegenerative diseases, but the molecular chain of events responsible for brain cell death in these conditions are the same. (
  • Nucleus of a cell undergoing parthanatos cell death. (
  • Research partners Dr. Ted Dawson, Ph.D., now director of the Institute for Cell Engineering at the Johns Hopkins University School of Medicine, and Valina Dawson, Ph.D., professor of neurology, and their research group conducted experiments on laboratory-grown cells to determine the culprit in the event chain that ultimately causes cell death. (
  • Previous research indicated that when a protein - mitochondrial apoptosis-inducing factor (AIF) - moves from its residing location in the energy-producing mitochondria of the cell to the nucleus, it causes the genome housed in the nucleus to be carved up, leading to cell death. (
  • While the transfer of AIF into the nucleus leads to cell death, AIF is not responsible for the DNA being carved. (
  • Wang identified 160 possible protein candidates and stopped each of them being produced one by one in lab-grown human cells, in order to determine whether cell death would be prevented if one protein was eliminated. (
  • Of all the 160 proteins, the team identified macrophage migration inhibitory factor (MIF) at the heart of the cell-death process. (
  • Additionally, Dr. Dawson and colleagues have discovered chemical compounds that can block the action of MIF in the lab-grown cells and, as a result, protect them from cell death. (
  • The cell death process has four major stages. (
  • The first, the induction stage, includes several changes initiated by ischemia and reperfusion that are very likely to play major roles in cell death. (
  • The second stage of cell death involves the long-term changes in macromolecules or key metabolites that are caused by the perpetrators. (
  • The third stage of cell death involves long-term damaging effects of these macromolecular and metabolite changes, and of some of the induction processes, on critical cell functions and structures that lead to the defined end stages of cell damage. (
  • The fourth stage is the progression to the morphological and biochemical end stages of cell death. (
  • Quite little is known of how the perpetrators affect the structures and functions and whether and how each of these changes contribute to cell death. (
  • Although it is not fully established for all cases, the major driving force for the necrotic cell death process, and very possibly the other processes, appears to be the generation of free radicals and peroxynitrite. (
  • These include determining the triggers for apoptosis and autophagocytosis and establishing greater confidence in most of the cellular changes that are hypothesized to be involved in cell death. (
  • A very important outstanding issue is identifying the critical functional and structural changes caused by the perpetrators of cell death. (
  • They found that a high dose of vitamin C by itself caused DNA damage and cell death which was much more pronounced, especially before radiation, the journal Free Radical Biology and Medicine reports. (
  • This is the trigger point leading to brain cell death, because key proteins essential for cell survival are not made. (
  • DAPk1 also mediate a range of activities from autophagy, membrane blebbing and DNA fragmentation ultimately leading to cell death. (
  • Focal brain ischemia reduces blood flow to a specific brain region, increasing the risk of cell death to that particular area. (
  • According to ABC News, the photos are pretty damn gruesome -- with one report stating, "[Osama] has a massive head wound above his left eye where he took bullet, with brains and blood visible. (
  • whether it's a child or an adult-you can say, "It's because their heart has stopped" or "Sadly, their brain has ceased to function. (
  • But in the early 1980s, a scientist trying to understand how birds learn to sing suggested that neuroscientists look again at neurogenesis in the adult brain and begin to see how it might make sense. (
  • For some neuroscientists, neurogenesis in the adult brain is still an unproven theory. (
  • Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis. (
  • The causes of brain ischemia vary from sickle cell anemia to congenital heart defects. (
  • Symptoms of brain ischemia can include unconsciousness, blindness, problems with coordination, and weakness in the body. (
  • Other effects that may result from brain ischemia are stroke, cardiorespiratory arrest, and irreversible brain damage. (
  • In 1974, Hossmann and Zimmermann demonstrated that ischemia induced in mammalian brains for up to an hour can be at least partially recovered. (
  • Accordingly, this discovery raised the possibility of intervening after brain ischemia before the damage becomes irreversible. (
  • The symptoms of brain ischemia reflect the anatomical region undergoing blood and oxygen deprivation. (
  • Ischemia within the arteries branching from the vertebral arteries in the back of the brain may result in symptoms such as dizziness, vertigo, double vision, or weakness on both sides of the body[citation needed]. (
  • The symptoms of brain ischemia range from mild to severe. (
  • Brain ischemia has been linked to a variety of diseases or abnormalities. (
  • Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison their healthy counterparts. (
  • Sickle cell anemia may cause brain ischemia associated with the irregularly shaped blood cells. (
  • The reason is because their brain has totally and irreversibly ceased to function. (
  • Results of the experiment, to be published on Thursday in the journal Nature, run contrary to long-accepted principles of brain death, which hold that vital cellular activity ceases irreversibly seconds or minutes after oxygen and blood flow are cut off. (
