(From Grant & Hackh's Chemical Dictionary, 5th ed)Hyperkalemia: Abnormally high potassium concentration in the blood, most often due to defective renal excretion. It is characterized clinically by electrocardiographic abnormalities (elevated T waves and depressed P waves, and eventually by atrial asystole). In severe cases, weakness and flaccid paralysis may occur. (Dorland, 27th ed)Paralysis, Hyperkalemic Periodic: An autosomal dominant familial disorder which presents in infancy or childhood and is characterized by episodes of weakness associated with hyperkalemia. During attacks, muscles of the lower extremities are initially affected, followed by the lower trunk and arms. Episodes last from 15-60 minutes and typically occur after a period of rest following exercise. A defect in skeletal muscle sodium channels has been identified as the cause of this condition. Normokalemic periodic paralysis is a closely related disorder marked by a lack of alterations in potassium levels during attacks of weakness.

Myocardial protection: the rebirth of potassium-based cardioplegia. (1/132)

The introduction of open-heart surgery more than 4 decades ago signaled a new era in medicine. For the 1st time, previously untreatable cardiac anomalies became amenable to surgical therapy. The use of the heart-lung machine seemed to grant the surgeon unlimited time in which to operate inside the heart. Still frustrated by poor operating conditions and the threat of air embolism, Denis Melrose introduced elective cardiac arrest in 1955. His use of a potassium citrate solution seemed to offer a safe method to effect a quiet, bloodless field. However, a few years after its inception, numerous reports began to question the safety of this approach, and the Melrose technique was abandoned in the early 1960s. Nearly 15 years elapsed before potassium-based cardioplegia regained popularity. During this period, topical hypothermia, coronary perfusion with intermittent aortic occlusion, and normothermic ischemia were evaluated and discarded. A few European investigators like Hoelscher, Bretschneider, and Kirsch had maintained their interest in chemical cardioplegia, and it was through their efforts that future researchers like Hearse and Gay spearheaded the return to potassium-based cardioplegia, which today forms the core of the cardiac surgeon's myocardial protective armamentarium and has contributed towards lowering operative mortality rates.  (+info)

Induction of immune tolerance in adult rabbits undergoing heterotopic cardiac transplantation. (2/132)

OBJECTIVE: To induce experimental immune tolerance in rabbits and observe its effects on heterotopic cardiac transplantation. METHODS: Donor's splenic lymphocytes pretreated with platinum metal chelator were injected into the recipient's mesenteric-portal vein. Cyclosporin A was perfused through the donor's heart. RESULTS: The injection of donor's splenic lymphocytes before transplantation could significantly prolong the survival time of the heterotopically transplanted heart. The effect of two injections was better than that of one. Radioactive tracer studies showed that the 99mTc-HMPAO tagged lymphocytes injected into the recipient rabbit were later concentrated in the liver, though initially they were distributed in multiple organs. The induced immune tolerance was antigen-specific, and it neither affect the other immune functions of the lymphatic system prominently nor exert any harmful effect on the recipient's liver and renal functions. The perfusion of cyclosporin A through the donor heart could block the glycosyl groups, such as D-glucose, D-mannose or N-acetyl-galactosamine on the surface of the myocardial cells, thus might change the antigenic expression, effectively preventing rejection of the graft by the host, and might be considered as a new method to block graft rejection in cardiac transplantation. The combined use of the above-mentioned two methods acted on both the host and the donor, thus reducing the exposed antigens on the donor organ as well as the immune reaction against the donor antigens, and resulting in synergistic effect in inducing immune tolerance in adult rabbits, and resulting in relatively long-term survival of transplanted hearts. CONCLUSION: This report may provide the experimental basis for inducing immune tolerance in clinical transplantation.  (+info)

Emerging concepts in the management of acute myocardial infarction in patients with diabetes mellitus. (3/132)

Although fibrinolysis has improved survival of patients after myocardial infarction (MI), such therapy is less likely to be administered to patients with diabetes. Furthermore, these patients present later (15 min) than nondiabetics. Moreover, even with the use of early potent fibrinolytic agents, patients with diabetes continued to suffer excessive morbidity and mortality. This finding is not related to the ability of fibrinolytic agents to restore complete reperfusion or increased risk of reocclusion of the infarct-related artery. Instead, the impaired ventricular performance at the noninfarct areas and metabolic derangements during the acute phase of MI may account for the adverse outcome. The efficacy of percutaneous coronary revascularization procedures for treatment of acute MI requires further evaluation. Therapeutic approaches should consider correcting these abnormalities to afford greater survival benefit for this subset of high-risk patients.  (+info)

Intercalated clear cells or pale cells in the sinus node of canine hearts? An ultrastructural study. (4/132)

Two types of sinus nodal cells were responsible for the main differences in the literature concerning the ultrastructure of the sinuatrial node: the intercalated clear cells and pale cells. Canine hearts were arrested by (1) aortic cross clamping, (2) coronary perfusion with the cardioplegic solution St. Thomas, and (3) coronary perfusion with the cardioplegic solution HTK (Custodiol(R)). After fixation by immersion or perfusion the sinus node tissue was prepared for electron microscopy. Following cardioplegic arrest and perfusion fixation, three nodal cell types in the non-ischemic sinuatrial node were observed: typical nodal cells, transitional cells, and intercalated clear cells. Less than 1% of the non-ischemic sinuatrial cells were intercalated clear cells, surrounded by typical nodal cells or transitional cells. The contractile apparatus of the intercalated clear cells was extremely poorly developed. Great structural variations in the mitochondria were observed in intercalated clear cells, variations that would not appear under conditions of ischemia. In contrast, after 15-25 min of ischemia at 25 degrees C the appearance of the sinus nodal cells was strikingly different from that of the non-ischemic sinuatrial cells. More than 10% of the nodal cells showed typical ischemic alterations, e.g., mitochondrial swelling, clumping of nuclear chromatin, loss of glycogen particles, and cell swelling in varying degrees. Because they look very pale, these nodal cells have been described as pale cells in the literature. Intercalated clear cells appear mainly in non-ischemic nodal tissue. Pale cells are ischemically damaged sinus nodal cells.  (+info)

Reduced cytosolic Ca(2+) loading and improved cardiac function after cardioplegic cold storage of guinea pig isolated hearts. (5/132)

BACKGROUND: Hypothermia is cardioprotective, but it causes Ca(2+) loading and reduced function on rewarming. The aim was to associate changes in cytosolic Ca(2+) with function in intact hearts before, during, and after cold storage with or without cardioplegia (CP). METHODS AND RESULTS: Guinea pig hearts were initially perfused at 37 degrees C with Krebs-Ringer's (KR) solution (in mmol/L: Ca(2+) 2.5, K(+) 5, Mg(2+) 2.4). One group was perfused with CP solution (Ca(2+) 2.5, K(+) 18, Mg(2+) 7.2) during cooling and storage at 3 degrees C for 4 hours; another was perfused with KR. LV pressure (LVP), dP/dt, O(2) consumption, and cardiac efficiency were monitored. Cytosolic phasic [Ca(2+)] was calculated from indo 1 fluorescence signals obtained at the LV free wall. Cooling with KR increased diastolic and phasic [Ca(2+)], whereas cooling with CP suppressed phasic [Ca(2+)] and reduced the rise in diastolic [Ca(2+)]. Reperfusion with warm KR increased phasic [Ca(2+)] 86% more after CP at 20 minutes and did not increase diastolic [Ca(2+)] at 60 minutes, compared with a 20% increase in phasic [Ca(2+)] after KR. During early and later reperfusion after CP, there was a 126% and 50% better return of LVP than after KR; during later reperfusion, O(2) consumption was 23% higher and cardiac efficiency was 38% higher after CP than after KR. CONCLUSIONS: CP decreases the rise in cardiac diastolic [Ca(2+)] observed during cold storage in KR. Decreased diastolic [Ca(2+)] and increased systolic [Ca(2+)] after CP improves function on reperfusion because of reduced Ca(2+) loading during and immediately after cold CP storage.  (+info)

Leukocyte-depleted continuous blood cardioplegia for coronary artery bypass grafting. (6/132)

Many cardiac surgeries are performed with blood cardioplegia. However, some studies suggest that activated neutrophils form blood cardioplegia can cause reperfusion injury. In this study we assessed myocardial protection using a leukocyte-depleted cardioplegic solution. Patients undergoing elective coronary artery bypass grafting (CABG) with continuous blood cardioplegia were divided into two groups: the LD group, which received leukocyte-depleted blood cardioplegia (n = 11); and the control group, which received nonfiltered blood cardioplegia (n = 11). IL-6, IL-8, CK-MB, and troponin T were measured in the coronary sinus blood immediately after the release of the aortic cross-clamp. Cytokine concentrations were also measured upon the patient's return to the ICU. The total dopamine and dobutamine doses, hemodynamic measurements after surgery, and the leukocyte filtration rate were also measured. During antegrade cardioplegia infusion, leukocytes were almost completely removed (filtration rate: 85.8+/-4.0%). However, during terminal warm cardioplegia, leukocyte removal decreased (filtration rate: 39.9+/-7.8%). Immediately after the release of the aortic cross-clamp, plasma CK-MB and troponin T concentrations were significantly lower in the LD group (17.7+/-1.9 U/l and 0.017+/-0.002 ng/ml, respectively) than in the control group (30.3+/-3.6 U/l and 0.072+/-0.029 ng/ml, respectively). The IL-6 and IL-8 concentrations were similar in the LD group and the control group. After the return to the ICU, the CK-MB and troponin T concentrations were similar in the two groups. No significant differences were found in the total doses of dopamine or dobutamine after surgery in the two groups (99+/-77 vs 101+/-128 microg/kg/min). No significant differences were found in the hemodynamic parameters after surgery in the two groups. In patients undergoing CABG with continuous blood cardioplegia, leukocyte-depleted blood cardioplegic solution may attenuate reperfusion injury.  (+info)

Does cardioplegia type affect outcome and survival in patients with advanced left ventricular dysfunction? Results from the CABG Patch Trial. (7/132)

BACKGROUND: There is controversy regarding which cardioplegic solution, temperature, and route of administration provides superior protection. The CABG Patch Trial enrolled a high-risk group of coronary artery disease patients with an ejection fraction of <36%. Thus, they constitute an ideal group to benefit most from optimal cardioplegic protection. METHODS AND RESULTS: All patients randomized into the trial were compared with respect to the use of blood and crystalloid cardioplegia. In addition, a questionnaire was sent to surgeons requesting blood cardioplegic temperature and route. Patients receiving crystalloid cardioplegia versus those receiving blood cardioplegia were found to have significantly more operative deaths (2% versus 0.3%, P:=0.02), postoperative myocardial infarctions (10% versus 2%, P:<0.001), shock (13% versus 7%, P:=0. 013), and postoperative conduction defects (21.6% versus 12.4%, P:=0. 001). Despite this, early death (6% crystalloid versus 4% blood cardioplegia) and late death (24% crystalloid versus 21% blood cardioplegia) statistics were not significantly different. Patients receiving normothermic blood had less postoperative right ventricular dysfunction (10%) than did patients receiving cold blood (25%) or cold blood with warm reperfusion (30%) (P:=0.004). There was no significant difference in early or late death. Finally, patients who received combined antegrade and retrograde cardioplegia had significantly less inotrope use (71% versus 84%, P:=0.002), right ventricular dysfunction (23% versus 41%, P:=0.001), and postoperative balloon pump use (12% versus 19%, P:=0.02) than did those who received antegrade cardioplegia. There was no difference in survival. CONCLUSIONS: Blood cardioplegia and combined antegrade and retrograde cardioplegia are superior to crystalloid and antegrade cardioplegia alone for postoperative morbidity. Despite this, there is no significant difference in early or late survival.  (+info)

Cardioplegic strategies for calcium control: low Ca(2+), high Mg(2+), citrate, or Na(+)/H(+) exchange inhibitor HOE-642. (8/132)

BACKGROUND: Ca(2+) overload plays an important role in the pathogenesis of cardioplegic ischemia-reperfusion injury. The standard technique to control Ca(2+) overload has been to reduce Ca(2+) in the cardioplegic solution (CP). Recent reports suggest that Na(+)/H(+) exchange inhibitors can also prevent Ca(2+) overload. We compared 4 crystalloid CPs that might minimize Ca(2+) overload in comparison with standard Mg(2+)-containing CP: (1) low Ca(2+) CP (0.25 mmol/L), (2) citrate CP/normal Mg(2+) (1 mmol/L Mg(2+)), (3) citrate CP/high Mg(2+) (9 mmol/L Mg(2+)), and (4) the addition of the Na(+)/H(+) exchange inhibitor HOE-642 (Cariporide). We also tested the effect of citrate titration in vitro on the level of free Ca(2+) and Mg(2+) in CPs. METHODS AND RESULTS: Isolated working rat heart preparations were perfused with oxygenated Krebs-Henseleit buffer and subjected to 60 minutes of 37 degrees C arrest and reperfusion with CPs with different Ca(2+) concentrations. Cardiac performance, including aortic flow (AF), was measured before and after ischemia. Myocardial high-energy phosphates were measured after reperfusion. The in vitro addition of citrate to CP (2%, 21 mmol/L) produced parallel reductions in Mg(2+) and Ca(2+). Because only Ca(2+) was required to be low, the further addition of Mg(2+) increased free Mg(2+), but the highest level achieved was 9 mmol/L. Citrate CP significantly impaired postischemic function (AF 58.3+/-2. 5% without citrate versus 41.6+/-3% for citrate with normal Mg(2+), P:<0.05, versus 22.4+/-6.2% for citrate with high Mg(2+), P:<0.05). Low-Ca(2+) CP (0.25 mmol/L Ca(2+)) significantly improved the recovery of postischemic function in comparison with standard CP (1.0 mmol/L Ca(2+)) (AF 47.6+/-1.7% versus 58.3+/-2.5%, P:<0.05). The addition of HOE-642 (1 micromol/L) to CP significantly improved postischemia function (47.6+/-1.7% without HOE-642 versus 62.4+/-1. 7% with HOE-642, P:<0.05). Postischemia cardiac high-energy phosphate levels were unaffected by Ca(2+) manipulation. CONCLUSIONS: (1) A lowered Ca(2+) concentration in CP is beneficial in Mg(2+)-containing cardioplegia. (2) The use of citrate to chelate Ca(2+) is detrimental in the crystalloid-perfused isolated working rat heart, especially with high Mg(2+). (3) The mechanism of citrate action is complex, and its use limits precise simultaneous control of Ca(2+) and Mg(2+). (4) HOE-642 in CP is as efficacious in preservation of the ischemic myocardium as is the direct reduction in Ca(2+).  (+info)

Activated protein C in the cardioplegic solution on a porcine model of coronary ischemia-reperfusion has deleterious hemodynamic effects ...
OBJECTIVE: Depolarizing potassium cardioplegia has been increasingly linked to left ventricular dysfunction, arrhythmia, and microvascular damage. We tested a new polarizing normokalemic cardioplegic solution employing adenosine and lidocaine as the arresting, protecting, and preserving cardioprotective combination. Adenosine hyperpolarizes the myocyte by A1 receptor activation, and lidocaine blocks the sodium fast channels. METHODS: Isolated perfused rat hearts were switched from the working mode to the Langendorff (nonworking) mode and arrested for 30 minutes, 2 hours, or 4 hours with 200 µmol/L adenosine and 500 µmol/L lidocaine in Krebs-Henseleit buffer (10 mmol/L glucose, pH 7.7, at 37°C) or modified St Thomas Hospital solution no. 2, both delivered at 70 mm Hg and 37°C (arrest temperature 22°C to 35°C). RESULTS: Adenosine and lidocaine hearts achieved faster mechanical arrest in (25 ± 2 seconds, n = 23) compared with St Thomas Hospital solution hearts (70 ± 5 seconds, n = 24; ...

Problem- the heart is not susceptible, you cant wait 4/5 mins then take a heart. Bec certain tissues in the body are much more metabolically active than others and If you wait the period of time without circulation they become unusable. The heart is so metabolically active that if u wait even a short period if time after death the heart no longer functions the cells are damaged and when u take the heart and try to implant into someone else it will not function. The only way to preform as successful heart transplant is to open the chest of the donor while the heart is still beating, then u stop the heart urself with injecting preservative cardioplegic solution which perseveres the function of the cells and rapidly cool the heart in a bath of cardioplegic solution then transport the heart and transplant into the recipient and warm it up again the heart. If u follow Jewish law and take the heart after u have waited, it will not be useful- see the problem in heart transplant.. The cornea isnt a ...
Remote ischemic preconditioning (RIPC) protocol before coronary artery bypass surgery consists of 3 cycles of 5 minutes left upper arm ischemia by inflation of a blood pressure cuff to 200 mmHg and 5 minutes of reperfusion after induction of anesthesia before coronary artery bypass surgery.

Results 53 patients were included in the data analysis, comprising 23 urgent patients and 30 elective patients. Mean age of the cohort was 65.3 (±9.8) years, and the men population accounted for the majority (n=47, 88.7%). In the urgent group, half of the patients received prophylaxic doses of dalteparin once daily (n=12, 52.2%), followed by 4 patients (17.4%) who received the dose for acute coronary syndrome. Antiplatelet therapy was used before CABG surgery in 18 urgent patients (78.3%). Also, all patients were given dalteparin (prophylaxic dose: n=45, 84.9%; treatment dose: n=8, 15.1%) and dual antiplatelets after CABG. There was no symptomatic VTE events within the audit period. Nevertheless, 5 urgent patients (9.4%) suffered from moderate to severe bleeding incidences during surgery, with a significant difference between groups (p=0.012). ...
To visualize the presence and anatomic localization of TNF-alpha within the myocardium, immunohistochemical studies were performed in three groups of isolated hearts: group 1, four hearts undergoing 1 h of cardioplegic ischemia; group 2, four hearts undergoing similar ischemia receiving anti-TNF mAb in the cardioplegic solution (50 mg/ml, total given dose of 1.5 mg; hearts from these two groups were freshly excised immediately after ischemia); and group 3, four isolated hearts excised after 120 min of perfusion (without ischemia) that served as a control group.. Excised hearts were fixed in 10% neutral buffered formalin (Z-fix; Anatech, Ltd.) at room temperature for 18 to 24 h. The tissue was then dehydrated, embedded in paraffin and sectioned (5-μm sections) in a standard manner. Immunohistochemical studies were performed by using a streptavidin-biotin immunoperoxidase method according to the manufacturers instructions (Zymed Lab. Inc.). All reagents were prepared with a dilluent consisting ...
TY - JOUR. T1 - Potassium-induced cardioplegia during normothermic cardiac arrest. Morphologic study of the effect of varying concentrations of potassium on myocardial anoxic injury..

N2 - Most corrective procedures as well as myocardial revascularization require a period of cardiac arrest, and numerous methods have been proposed to protect the myocardium during this ischemic episode. Potassium-induced cardioplegia is one method that appears to be of benefit in this setting. Since it is recognized that myocardial necrosis may result at very high doses of potassium, we examined the effect of varying concentrations of potassium on myocardial anoxic injury. Using an isolated rat heart preparation, we evaluated anoxic injury occurring with cardioplegic solutions containing various concentrations of K+, ranging from 15 to ...
Conventional CABG uses cardiopulmonary bypass (CPB) and cardiac arrest to provide a stationary heart to facilitate surgery. This technique causes an obligate period of global myocardial ischemia that is attenuated by cardioplegic arrest of the heart. Currently, the optimal method for intraoperative myocardial protection is blood cardioplegia, but this is still associated with low cardiac output syndrome in 10% of cases.12-14 Over the last decade, interest has reemerged in beating heart ("off-pump") surgery, which avoids CPB, cardioplegic arrest, and consequently, the global "ischemic time." In previous work by our group, it has been shown that in patients with normal left ventricular (LV) function, off-pump CABG is associated with improved early cardiac function compared with conventional CABG with the use of crystalloid cardioplegia.15 Although heart failure patients could potentially benefit from this improvement in early cardiac function, they may not be able to sustain an adequate ...
Two months after hospital discharge, she developed marked exercise intolerance, dyspnea, and orthopnea. The patient was admitted for further investigation. Her pulse rate was 120 beats per minute, blood pressure 90/45 mmHg, and respiratory rate was 35 breaths per minute. A CT scan (Figure 1) and echocardiography (Figure 2) revealed a large tumor mass in the right ventricle extending to the right ventricular outflow tract and the proximal main pulmonary artery. The mass occasionally caused obstruction of the flow of blood through the tricuspid valve into the right ventricle. CT scan of abdomen showed no local recurrence of the liver tumor. The patient was operated upon urgently; a standard procedure was performed with moderate hypothermia, cardiopulmonary bypass, and bicaval cannulation. The heart was arrested with a cold blood cardioplegic solution administered intermittently. At surgery, a right ventriculotomy revealed a large cauliflower-like soft tissue mass of gray-yellow color invading ...

In the DN group, a 20 mL/kg single dose was administered. In the STH group, a 30 mL/kg dose was administered, followed by repeated doses at 25- to 30-minute intervals. The primary outcome was cardiac index that was measured 4 times intra- and postoperatively. Troponin-I, interleukin-6, and tissue necrosis factor-alpha were measured. Myocardial biopsy was obtained to assess electron-microscopic ultrastructural changes. Cardiac indices were significantly higher in the DN group than in the STH group 2 hours after termination of cardiopulmonary bypass (P = 0.0006), after 6 hours (P = 0.0006), and after 24 hours (P ≤ ...

To The Editor:. We read with interest the article by Howell et al.1 We wish to offer some brief comments. Although the concept has been around for nearly 50 years, glucose-insulin-potassium still lacks an established protocol.. Uncertainties surrounding glucose-insulin-potassium are, in part, due to the different contexts, doses, timing, and protocols used.1 The clinical cardiologist may inquire about the rationale for the investigators choice of the specific protocol used in the Hypertrophy, … ...

August 2000 I am sitting in the Paediatric Intensive Care Unit at Guys Hospital, London. My granddaughter, Holly, was rushed here by ambulance at 2.30 this morning from St Thomas hospital. She has been diagnosed with pneumococcal meningitis. My daughter and I were not allowed to travel with her in the ambulance. We followed in a taxi. The ambulance tore through the deserted London streets, its siren blaring and its lights flashing. Hannah and I are silent. We are beyond speaking.. Hollys eyes are closed. At just fourteen months old, she looks tiny and vulnerable in the big cot. There are tubes everywhere and a nurse is sitting at the end of the cot looking at a screen intently. I dont know what to do. I stroke Hollys head cautiously. She flinches. I stroke her hand with one finger and sing quietly. I know what her favourite songs are. I imagine she is listening to me, but I cant be sure.. I think it was when we were back in St Thomas after leaving the Intensive Care Unit at Guys that ...
An improved method of using a single catheter to infuse blood to the heart, clamping the aorta and delivering a cardioplegia solution. Patient trauma is significantly reduced using a single cannulation. A single catheter (10, 90, 92) is used having a unique balloon (56, 93, 102) for occluding the aorta. In a first embodiment, a single catheter (10) is positioned upwardly in the aorta to infuse oxygenated blood into the ascending aorta via an infusion lumen (72) terminating at the distal end (54), with cardioplegia solution being delivered via openings (82) defined closely adjacent the balloon (56) on the proximal side of the balloon. The inflated balloon (56) isolates the two delivery openings (72,82) from one another to facilitate use of an extracorporeal circuit. In a second embodiment, a single catheter (90) can be positioned downwardly in the aorta to infuse blood via openings (82) into the ascending aorta proximate the subclavian artery, and deliver cardioplegia solution via the distal opening (72)

Our sleep patterns are dictated by light and hormones. When light dims in the evening, we produce a chemical called melatonin, which gives the body clock its cue, telling us its time to sleep. "The problem is that society has changed," says Professor Paul Gringras, consultant paediatrician and director of the Evelina Paediatric Sleep Disorder Service at Guys and St Thomas Hospital in London.. "Artificial light has disrupted our sleep patterns. Bright room lighting, TVs, games consoles, mobiles, tablets and PCs can all emit enough light to stop the natural production of melatonin." These are all distractions, which teens may use well into the night.. "That wouldnt be a problem if there was no need to get up early in the morning for school," says Professor Gringras. "The early morning wake-ups mean theyre not getting the average eight to nine hours of sleep. The result is a tired and cranky teenager.".

Few people are aware that there is a clear link between obesity and cirrhosis. Photograph: Dominic Lipinski/PA. Doctor Jude Oben had grim news for a patient last week. The liver expert told the 60-year-old man that he had cirrhosis - for the second time in his life.. Only four years ago Obens patient had required a liver transplant after his first bout of cirrhosis, a condition he had contracted because he was obese. Unfortunately my patient continued to overeat and remained obese, said Oben, a hepatologist based at the Royal Free and St Thomas hospitals in London. As a result, he contracted cirrhosis again. Sadly, I had to tell him that this time it was very unlikely he would be given another liver.. Obens patient is one of a tidal wave of cases of cirrhosis, triggered by obesity, that threatens to sweep through hospitals across the UK. People might be aware that there are metabolic disorders such as diabetes and high blood pressure associated with obesity, but very few know about the ...

Whether it was Voltaire, Winston Churchill or someone else who said it, the words with great power comes great responsibility have never been truer. There are many benefits of genetic testing and personalised medicine for people whove already been diagnosed with a disease. However, there are still serious questions to consider when it comes to using genetic testing for diagnosis, screening and prevention. We spoke to Sarah Rose, a genetic counsellor at Guys and St Thomas Hospital to ask about some of the issues she deals with on a daily basis. She said: "Genetic testing is available for men with, or at risk of, prostate cancer on the NHS, but only for men with a very strong family history of prostate, breast and/or ovarian cancer.. "These are the cancers most strongly linked to BRCA1 or BRCA2 mutations, which are the only known prostate cancer genes we can test for inherited mutations at the moment. This is because we can only offer testing when we know what the associated risk of a ...

The second phase of the nursing procedure is diagnosing. In light of this, it is thought that, in oncology hospital solutions, the nursing process with emphasis on the diagnosis phase is important to the oncology hospital services because of a high frequency of physical and mental difficulties that compromise the standard of life of patients undergoing cancer therapy. 1 form of theory may not be applied every patient stipulation.. Whats more, a valuable part of superior patient care is dependent on preventative measures. In the event the outcomes are high, then you ought to seek out guidance about the correct treatment to fix the high ketone level and the protocol for re-testing for ketones until the outcome is negative. Its also hard to treat and might wind up in local water supply.. The very first step of the nursing procedure is called assessment. To assist you in getting started, here are a few of the important nursing care plans for hypertension you will need to prepare. Perhaps you might ...

Background:: The exact mechanisms that underlie the pathological processes of myocardial ischemia in humans are unclear. Cardiopulmonary bypass with cardioplegic arrest allows the authors to examine the whole transcriptional profile of human left ventricular myocardium at baseline and after exposure to cold cardioplegia-induced ischemia as a human ischemia model. Methods:: The authors obtained biopsies from 45 patients undergoing aortic valve replacement surgery at baseline and after an average of 79 min of cold cardioplegic arrest. Samples were RNA sequenced and analyzed with the Partek® Genomics Suite (Partek Inc., St. Louis, MO) for differential expression. Ingenuity Pathway Analysis (Ingenuity Systems, Redwood City, CA) and Biobase ExPlain (Biobase GmbH, Wolfenbuettel, Germany) systems were used for functional and pathway analyses. Results:: Of the 4,098 genes with a mean expression value greater than 5, 90% were down-regulated and 9.1% were up-regulated. Of those, 1,241 were significantly ...
Minimally invasive surgery is associated with a faster postoperative recovery because of reduced postoperative pain and improved respiratory function, especially in elderly patients. We began using a minimally invasive approach ismall parasternal incision jfor isolated aortic valve replacement iMICS AVR jfrom January 2011. Between January 2011 and February 2012, 32 patients underwent MICS AVR surgery. The mean age was 73 years irange 57-85 years j;69% were women. MICS AVR was performed through a skin incision of 6.5 }0.5cm along the third intercostal space. Cardiopulmonary bypass was established through the right femoral artery and vein. The patients were cooled to 28 , the aorta was crossclamped with a flex clamp, and antegrade cardioplegic solution was given into the aortic root or selectively into the coronary ostia. The aortic valve procedure was performed in a standard fashion. If the distance to the aortic valve was too far, we used surgical instruments for minimally invasive surgery. ...

There was no significant difference in the rate of progression to MI among patients who received GIK (n = 200; 48.7%) versus those who received placebo (n = 242; 52.6%) (odds ratio [OR], 0.88; 95% confidence interval [CI], 0.66-1.13; p = 0.28). Thirty-day mortality was 4.4% with GIK versus 6.1% with placebo (hazard ratio [HR], 0.72; 95% CI, 0.40-1.29; p = 0.27). The composite of cardiac arrest or in-hospital mortality occurred in 4.4% with GIK versus 8.7% with placebo (OR, 0.48; 95% CI, 0.27-0.85; p = 0.01). Among patients with ST-segment elevation (163 with GIK and 194 with placebo), progression to MI was 85.3% with GIK versus 88.7% with placebo (OR, 0.74; 95% CI, 0.40-1.38; p = 0.34); 30-day mortality was 4.9% with GIK versus 7.7% with placebo (HR, 0.63; 95% CI, 0.27-1.49; p = 0.29).

Serious adverse events occurred in 6.8% (n = 28) with GIK ...
Cardioplegia is intentional and temporary cessation of cardiac activity, primarily for cardiac surgery. The word cardioplegia combines the Greek cardio meaning the "heart", and plegia "paralysis". Technically, this means arresting or stopping the heart so that surgical procedures can be done in a still and bloodless field. Most commonly, however, the word cardioplegia refers to the solution used to bring about asystole of the heart, or heart paralysis. One of the first physicians to use the term cardioplegia was Dr. Lam in 1957. However his work on the myocardial protection was preceded serendipitously by Sidney Ringer in the late 1800s. At that time Ringer and colleagues noticed that tap water had the ability to increase contractility of the heart, likely due its high calcium content. Sidney ringer also commented on the importance of potassium ion concentration on depressing intrinsic heart rhythmn. Through a series of experiments performed on frog and canine hearts, reversible arrest was ...
Ischaemic heart disease is a leading cause of mortality in the western world. A number of patients undergo coronary artery bypass graft (CABG) surgery as treatment for ischaemic heart disease. With the rise of interventional procedures, patients who are coming to have CABG surgery are higher risk1. Remote ischaemic preconditioning (RIPC) has been shown to reduce perioperative myocardial injury (PMI) in patients having CABG even when cold blood cardioplegia or intermittent cross clamp fibrillation is used as cardioprotective measures. These patients have a general anaesthetic with multiple infusions including Glyceryl Trinitrate (GTN). The use of GTN in these patients is based on theoretical assumptions of coronary vasodilation pre operatively along with maintaining graft potency postoperatively. We intend to investigate the effect of GTN in patients undergoing cardiac surgery being subjected to RIPC in its role as a Nitric Oxide (NO) donor. Exogenous NO has been shown to be cardioprotective in ...

Szabo Z, Arnqvist H, Hakanson E, Jorfeldt L, Svedjeholm R: Effects of high-dose glucose-insulin-potassium on myocardial metabolism after coronary surgery in patients with type II diabetes. Clin Sci 101:37-43, 2001. Findings. Szabo et al. investigated the use of a glucose-insulin-potassium infusion (GIK) on myocardial substrate utilization after coronary surgery in 20 patients with type 2 diabetes. Patients were randomly allocated to either postoperative high-dose GIK or standard postoperative care, including insulin infusion, if necessary, to keep blood glucose ,10 mmol/l. Myocardial substrate utilization and hemodynamic status were studied using coronary sinus catheters and Swan-Ganz catheters, respectively. Infusion of GIK caused a shift toward carbohydrate utilization, with significant lactate uptake throughout the study period and significant uptake of glucose after 4 h. Arterial levels of nonesterified fatty acids and β-hydroxybutyric acid decreased, and after 1 h no significant uptake of ...
Though the plot of the novel is rather sad and scary, I have read many "true-crime" novels where the serial killer kills about fifteen women before cutting them up and burying them. The details in some of those novels are truly disgusting yet this is the book that frightens me most of all. Four murders. Seems like a small amount compared to fifty but losses of life nonetheless. So chilling and personal is Capotes In Cold Blood that I was a bit nervous about keeping the book by my bed. Capote pulls us right into the lives of the Clutter family: from Nancys social personality to Kenyons quiet yet intelligent attitude. We get glimpses of their rooms and their habits. We stay with them for a few days, observing through Capotes trained eye of their lifestyles and routines. We become so fully immersed in the details of their lives that when they are ripped from us, we feel the terrifying loss. One line in particular jolted me and that was right after Nancy Clutter has been discovered dead and Mr. ...

Author Bio:. Kelly qualified from Guys, Kings and St Thomas in 2003. She is currently working as an associate at Regency Dental, Swanage and has been a member of the IAS Academy since completing here initial training in 2015.. The Case. A 48-year-old female patient was referred to me by a colleague in-house. She was unhappy with the appearance of her rotated upper centrals and misaligned lower incisors as they were difficult to clean and kept getting stained. She had been considering veneers when she saw information on the IAS Inman Aligner in the waiting room.. With very little dental history, no restorations and a regular attender to the dentist and hygienist, the patient was medically fit and well. A thorough orthodontic assessment revealed a Class I occlusion on a Class I skeletal base. There was mild crowding in the upper and lower labial segments, the upper centrals were rotated and the upper canines buccally placed with space distal to these. Periapical radiographs taken of the ...

New and more conservative approaches in treatment are a major advance. For 30 years the US National Institutes of Health have dominated the treatment of lupus nephritis with controlled trials of monthly high dose intravenous pulse cyclophosphamide, now the standard treatment for nephritis and severe lupus. However, adverse effects such as ovarian failure and infections are significant with prolonged treatment.1 As most lupus patients are women of childbearing age, this price has been high and patients and clinicians are questioning this protocol. Recent studies offer two different approaches that may be as effective and better tolerated.. The use of low dose cyclophosphamide, pioneered at St Thomas Hospital, London, was recently compared with the US regimen in a European study.2 3 There were similar improvements in renal variables in proliferative lupus nephritis with both regimens but with a tendency to lower toxicity in the group receiving cyclophosphamide at low dosages. This probably ...

TY - JOUR. T1 - Comparison of myocardial protection with nifedipine and potassium. AU - Magee, P. G.. AU - Flaherty, J. T.. AU - Bixler, T. J.. AU - Glower, D.. AU - Gardner, T. J.. AU - Bukley, B. H.. AU - Gott, V. L.. PY - 1979/1/1. Y1 - 1979/1/1. N2 - Nifedipine, a slow-channel calcium blocker, is thought to provide useful myocardial protection during prolonged total ischemia and reperfusion. An isolated, isovolumic, feline heart model was used to assess the effectiveness of nifedipine in both cardioplegic (100 μg/10 ml) and noncardioplegic (10 μg/10 ml) doses for providing myocardial preservation during 90 minutes of hyperthermic ischemic arrest and 45 minutes of normothermic reperfusion. Use of nifedipine was compared to hypothermia (27°C) alone and to hypothermia with potassium cardioplegia. Ventricular function was assessed by recovery of isovolumic left ventricular developed pressure and dP/dt. Myocardial carbon dioxide tension (PCO2) and myocardial oxygen tension (PO2) were measured ...
Background. Levosimendan is a calcium-sensitizing inotropic agent that prevents myocardial contractile depression following cardiac surgery. Levosimendan has also anti-apoptotic properties, but the role of this mechanism is not clear. We studied whether levosimendan prevents cardiomyocyte apoptosis and post-operative stunning after either intracoronary administration or intravenous infusion in an experimental model. Methods. Pigs (n=24) were subjected to 40 minutes of global, cardioplegic ischemia under cardiopulmonary bypass and 240 minutes of reperfusion. L-IV group received intravenous infusion of levosimendan (65 μg/kg) 40 minutes before ischemia and L-IC group received levosimendan (65 μg/kg) during ischemia administered intracoronary. Control group was operated without levosimendan. Echocardiography was performed to all animals. Apoptosis was determined from transmyocardial biopsies taken from left ventricle using TUNEL assay and immunohistochemistry of active caspace-3. Results. Apoptosis was

Released eight years after the event, Robert Brookss In Cold Blood is an adaptation of the infamous book by Truman Capote, about an unfathomable crime that took place in Holcomb, Kansas in 1959. Acting on a tip-off, newly released convicts Perry Smith (Robert Blake) and Dick Hickock (Scott Wilson) decided to rob the home of the Cutter family, convinced they had a safe full of cash. Armed with rope, a knife and a shotgun, and full of confidence that their plan was foolproof, they drove across state lines to the remote farm, with little intention of leaving any witnesses behind. The result was four dead bodies, and Smith and Hickock on the run. Brooks methodically divided the film into parts: the first cuts together scenes of the perpetrators and their victims. The Cutters, the teen children especially, are all wholesome, mid-west innocence, the slightly saccharine scenes overlaid with a sentimental score - as opposed to the cool 60s jazz that drives the scenes with Smith and Hickock, both ...
A coronary sinus catheter for the retrograde infusion of cardioplegia solutions into the coronary sinus. The catheter is adapted for improved retention in the coronary sinus. The catheter comprises a catheter tube having infusion, pressure-sensing and balloon-inflation lumens, an inflatable balloon and a pressure sensor tube in fluid communication with the balloon-inflation lumen for sensing pressure in the inflatable balloon. The internal volume of the pressure sensor tube is relatively non-expansible relative to the internal volume of the inflation balloon in normal operation of the catheter. The balloon includes a plurality of segmented annular ribs.
FDA released a MedWatch Safety Alert on October 15 stating that the sterility of any injectable drugs, including ophthalmic drugs that are injectable or used in conjunction with eye surgery, and cardioplegia solutions produced by NECC is of significant concern. FDA advised healthcare providers to follow-up with patients who were administered any of these products purchased from or distributed by NECC on or after May 21, 2012. CDC recommends that clinicians remain vigilant for the possibility that infections may have resulted from injection of NECC products, and that routine laboratory and microbiologic tests, including bacterial and fungal cultures, should be obtained as necessary by treating clinicians.. There has been no prior regular surveillance for adverse events following epidural steroid injections; however, infection is a known, although likely rare, risk that has been documented in the medical literature. Although CDC has received reports of illness in patients who have received the ...

Dylan Marlais Thomas is perhaps Wales best-known writer. He wrote poems, short stories and scripts for film and radio, which he often performed himself. His public readings in America were highly acclaimed, and his mellifluous voice was celebrated in his numerous radio broadcasts. Dylan Thomas most celebrated works include Under Milk Wood, Do Not Go Gentle Into That Good Night, Fern Hill and A Childs Christmas In Wales. Dylan Thomas early years shaped him, both as a person and as a writer. He was born on 27 October 1914 at 5 Cwmdonkin Drive in Swansea, a newly built semi-detached house his parents had bought earlier that year. The family - his father David John Thomas, known to all as DJ, his mother Florence, the young Dylan and his sister Nancy, eight years his elder - lived in the Uplands suburb of Swansea. It was a respectable area overlooking Swansea bay and the town. Dylan Thomas parents both spoke Welsh and had strong links to Welsh cultures and customs, but brought up their children ...
Thomas has highlighted in his memoirs the difficulty that he encountered "To make a business out of the views you had to have the necessary equipment, a sort of closed carriage or small caravan so that you could take all your chemicals and equipment with you. Having got as close as possible to the place you were going to photograph, everything was in the carriage and you could just pull a blind over the window to make a dark-room. When using the wet process, before the introduction of the dry plate, the plate had to be developed within a quarter of an hour of exposure. Many times on my journeys in the early years I would have loved to go a few miles to take a beautiful view or a notable place with some history to it, but I had to consider the cost before starting out, because I knew it would be hard to count on any profit. It also meant physical effort: you needed five bottles of various chemicals, a heavy bath weighing six pounds, plates and a cloth to make a dark-room, besides the camera and ...
Would you ever give a thrust at Isolert by using a fan funding platform? There is a lot of talk if this is a legit and moral way of doing things…. Well, this question is difficult to answer. We would never be a part of such a funding, because it is against our beliefs to begin with and I believe there must not be many black metal musicians that would make such a decision, as we generally like to keep things more "true". Would I stand against it? I wouldnt criticize a band which asks for 5.000-6.000 from its fans, because the band might ACTUALLY not be able to pay for the recording (not that a recording is always that expensive… It might be cheaper or even more expensive). I will not criticize an artist who will say: "give us 15€ and get the cd and your name on the thanks list", neither do I think that this is a cool thing to do. On the other hand, when one asks for 500.000 to build his own studio, then yes I despise him! When you exploit tour fans in cold blood and they dont have the ...

Aims: To examine the relative roles of genetic and environmental factors in central retinal thickness, by performing a classical twin study.. Methods: 310 subjects were recruited from the TwinsUK adult registry at St Thomas Hospital. Optical coherence tomography (Zeiss, stratus OCT3) was used to measure the average retinal thickness in the central 1 mm diameter area. The covariance of central retinal thickness (CRT), within MZ and DZ twin pairs, was compared and genetic modelling techniques were used to determine the relative contributions of genes and environment to the variation in CRT observed in this population.. Main outcome measure: CRT (average retinal thickness in the central 1 mm diameter area, centred on the fovea).. Results: The mean CRT of all subjects was 212.1 μm (range 165-277). CRT was statistically related to refractive error, with increasing myopia associated with a thinner CRT. CRT was more highly correlated within MZ twin pairs (r = 0.88) than with DZ twin pairs (r = 0.58), ...

Left ventricular dysfunction is a major determinant of outcome in coronary artery disease.1 However, not all dyssynergic areas are irreversibly damaged after infarction, as left ventricular dysfunction may be caused by myocardial stunning2 or by chronic reduction of blood flow,3 and the segments involved may show improved function after restoration of blood flow.4 Preservation of metabolism despite reduced function is the cornerstone of viable myocardium, but ultrastructural changes have been documented in viable tissue, including loss of sarcoplasmic reticulum, small scattered mitochondria, and glycogen deposition.5 These changes suggest a reduction in aerobic metabolism, but glucose uptake and utilisation are preserved and indeed have been used as a diagnostic marker of viability.6. Because of co-morbidity, myocardial revascularisation may be difficult to achieve in many patients with left ventricular dysfunction and viable myocardium. In these situations, medical treatment to improve left ...
The goal of cardiac transplantation is to retrieve and transplant a functional donor heart in the shortest amount of time. Once the donor/recipient match has been made, the heart is excised and induced into a hypothermic state with a cardioplegia solution. The heart is then transported to the recipients surgical site, where the recipient has been already prepared for transplant and placed on cardiopulmonary bypass. Ideally, the ischemic time of the heart, after procurement to implantation in the recipient, is less than four hours ...

A method of treatment of congestive heart failure comprises the steps of introducing an aortic occlusion catheter through a patients peripheral artery, the aortic occlusion catheter having an occluding member movable from a collapsed position to an expanded position; positioning the occluding member in the patients ascending aorta; moving the occluding member from the collapsed shape to the expanded shape after the positioning step; introducing cardioplegic fluid into the patients coronary blood vessels to arrest the patients heart; maintaining circulation of oxygenated blood through the patients arterial system; and reshaping an outer wall of the patients heart while the heart is arrested so as to reduce the transverse dimension of the left ventricle. The ascending aorta may be occluded and cardioplegic fluid delivered by means of an occlusion balloon attached to the distal end of an elongated catheter positioned transluminally in the aorta from a femoral, subclavian, or other appropriate

Title: Anti-CTLA4 Monoclonal Antibody Ipilimumab in the Treatment of Metastatic Melanoma: Recent Findings. VOLUME: 3 ISSUE: 2. Author(s):Marko Lens, Pier F. Ferrucci and Alessandro Testori. Affiliation:Kings College, Genetic Epidemiology Unit, St. Thomas Hospital, Lambeth Palace Road, London SE1 7EH, United Kingdom.. Keywords:CTLA-4, melanoma, antibody, ipilimumab, anti-tumour. Abstract: Use of monoclonal anti-CTLA4 antibodies represents a new promising strategy to block the activation of immunosuppressive CTLA-4 and thus induce tumour regression. This review is mainly focused on the report of existing data on the clinical use of Ipilimumab (formerly MDX-010) in the treatment of metastatic melanoma. Several phase I and II trials have been conducted to evaluate safety and efficacy of this form of immunotherapy either alone or in combination with vaccines or chemotherapy in patients with stage III or stage IV melanoma. Results from these studies are presented, patented and discussed. The ...
1) S.R.M Medical College, Tamil Nadu.. A.I.M.S, Kochi, Kerala.. One of the major issues raised by the cardiac surgical procedure requiring cardiopulmonary bypass is the question of myocardial protection. Retrograde coronary sinus cardioplegia (RCP) has gained wide spread use as a method of myocardial protection in a broad range of cardiac procedure.. The anatomic variations of the coronary sinus, its orifice in the right atrium and associated persistent left superior vena cava (PLSVC) may affect the distribution of retrograde cardioplegia. PLSVC results in excessive run off of the cardioplegia solution into PLSVC and right atrium, during RCP and leads to maldistribution.. During routine cadaveric dissection, in one male cadaver we found out PLSVC with dilated coronary sinus and the azygos vein on the left side, hemiazygos and accessory hemiazygos veins on the right side.. Embryological basis, clinical implications, sonographic pitfalls, associated congential cardiac anomalies and complications ...

One of the witnesses said there were five or six civilian-clad American security men in a convoy of five or six late model four-wheel-drive vehicles that was shepherding Dr Allawis entourage on the day. The US military and Dr Allawis office refused to respond to questions about the composition of his security team. It is understood that the core of his protection unit is drawn from the US Special Forces units..

A 50-year-old man who had coronary artery bypass grafting (LITA-LAD, RA-RCA, SVG-OM-PL) 6 years previously was admitted with acute dissection of the aorta (DeBakey type T). Preoperative computed tomography showed that all coronary bypass grafts were patent. We replaced the graft of the ascending aorta and reconstructed the coronary artery bypass by re-sternotomy, circulatory arrest (rectal temperature: 23.6 ), retrograde cerebral perfusion, and intermittent retrograde cardioplegia. Because a radial artery (RA) graft and a saphenous vein graft (SVG) each had intact orifices, we detached them together and attached the grafts back to the aortic graft wall. He was weaned successfully from cardiopulmonary bypass without difficulty and postoperative transthoracic echocardiography (TTE) showed good left ventricle (LV) function. Postoperative multidetector-row computed tomography (MDCT) showed that the RA graft and SVG were patent. By performing circulatory arrest and intermittent retrograde ...
