Regional survey of femoral neck fractures. (1/7364)In the South-west Thames Region 2619 patients (2105 women and 514 men) were discharged with a diagnosis of femoral neck fracture in 1974. The equivalent of a 250-bedded hospital was occupied throughout the year. The incidence, average length of stay, and mortality rate rose with increasing age and there were differences in these indices in the five health areas. These results confirm the enormous burden placed on the hospital service by patients with fracture of the femoral neck but suggest that differences in practice in the five areas may contribute to the size of the problem.

Incidence and duration of hospitalizations among persons with AIDS: an event history approach. (2/7364)OBJECTIVE: To analyze hospitalization patterns of persons with AIDS (PWAs) in a multi-state/multi-episode continuous time duration framework. DATA SOURCES: PWAs on Medicaid identified through a match between the state's AIDS Registry and Medicaid eligibility files; hospital admission and discharge dates identified through Medicaid claims. STUDY DESIGN: Using a Weibull event history framework, we model the hazard of transition between hospitalized and community spells, incorporating the competing risk of death in each of these states. Simulations are used to translate these parameters into readily interpretable estimates of length of stay, the probability that a hospitalization will end in death, and the probability that a nonhospitalized person will be hospitalized within 90 days. PRINCIPAL FINDINGS: In multivariate analyses, participation in a Medicaid waiver program offering case management and home care was associated with hospital stays 1.3 days shorter than for nonparticipants. African American race and Hispanic ethnicity were associated with hospital stays 1.2 days and 1.0 day longer than for non-Hispanic whites; African Americans also experienced more frequent hospital admissions. Residents of the high-HIV-prevalence area of the state had more frequent admissions and stays two days longer than those residing elsewhere in the state. Older PWAs experienced less frequent hospital admissions but longer stays, with hospitalizations of 55-year-olds lasting 8.25 days longer than those of 25-year-olds. CONCLUSIONS: Much socioeconomic and geographic variability exists both in the incidence and in the duration of hospitalization among persons with AIDS in New Jersey. Event history analysis provides a useful statistical framework for analysis of these variations, deals appropriately with data in which duration of observation varies from individual to individual, and permits the competing risk of death to be incorporated into the model. Transition models of this type have broad applicability in modeling the risk and duration of hospitalization in chronic illnesses. (+info)
The impact of a multidisciplinary approach on caring for ventilator-dependent patients. (3/7364)OBJECTIVE: To determine the clinical and financial outcomes of a highly structured multidisciplinary care model for patients in an intensive care unit (ICU) who require prolonged mechanical ventilation. The structured model outcomes (protocol group) are compared with the preprotocol outcomes. DESIGN: Descriptive study with financial analysis. SETTING: A twelve-bed medical-surgical ICU in a non-teaching tertiary referral center in Ogden, Utah. STUDY PARTICIPANTS: During a 54 month period, 469 consecutive intensive care patients requiring mechanical ventilation for longer than 72 hours who did not meet exclusion criteria were studied. INTERVENTIONS: A multidisciplinary team was formed to coordinate the care of ventilator-dependent patients. Care was integrated by daily collaborative bedside rounds, monthly meetings, and implementation of numerous guidelines and protocols. Patients were followed from the time of ICU admission until the day of hospital discharge. MAIN OUTCOME MEASURES: Patients were assigned APACHE II scores on admission to the ICU, and were divided into eight diagnostic categories. ICU length of stay, hospital length of stay, costs, charges, reimbursement, and in-hospital mortality were measured. RESULTS: Mortality in the preprotocol and protocol group, after adjustment for APACHE II scores, remained statistically unchanged (21-23%). After we implemented the new care model, we demonstrated significant decreases in the mean survivor's ICU length of stay (19.8 days to 14.7 days, P= 0.001), hospital length of stay (34.6 days to 25.9 days, P=0.001), charges (US$102500 to US$78500, P=0.001), and costs (US$71900 to US$58000, P=0.001). CONCLUSIONS: Implementation of a structured multidisciplinary care model to care for a heterogeneous population of ventilator-dependent ICU patients was associated with significant reductions in ICU and hospital lengths of stay, charges, and costs. Mortality rates were unaffected. (+info)
Reduction of laparoscopic-induced hypothermia, postoperative pain and recovery room length of stay by pre-conditioning gas with the Insuflow device: a prospective randomized controlled multi-center study. (4/7364)OBJECTIVE: To assess the efficacy and safety of Insuflow (Georgia BioMedical, Inc.) filter heater hydrator device in reducing the incidence, severity and extent of hypothermia, length of recovery room stay and postoperative pain at the time of laparoscopy. DESIGN: Prospective, randomized, blinded, controlled multi-center study. Patients underwent gynecologic procedures via laparoscopy; surgeons, anesthesiologists and recovery room personnel assessed the results. SETTING: Seven North American institutions. PATIENTS: Seventy-two women for safety evaluation and efficacy studies. INTERVENTIONS: Intraoperative pre-conditioning of laparoscopic gas with the Insuflow device (treatment) or standard raw gas (control) during laparoscopic surgery and postoperatively. MAIN OUTCOME MEASURES: Incidence, severity and extent of hypothermia, postoperative pain perception and length of recovery room stay. RESULTS: The Insuflow group had significantly less intraoperative hypothermia, reduced length of recovery room stay and reduced postoperative pain. Pre-conditioning of laparoscopic gas by filtering heating and hydrating was well tolerated with no adverse effects. The safety profile of the Insuflow pre-conditioned gas showed significant benefits compared to currently used raw gas. CONCLUSIONS: Pre-conditioning laparoscopic gas by filtering heating and hydrating with the Insuflow device was significantly more effective than the currently used standard raw gas and was safe in reducing or eliminating laparoscopic-induced hypothermia, shortening recovery room length of stay and reducing postoperative pain.

As-required versus regular nebulized salbutamol for the treatment of acute severe asthma. (5/7364)Current British guidelines for the administration of beta2-agonists in acute severe asthma recommend regular nebulized therapy in hospitalized patients, followed by as-required (p.r.n.) use via hand-held devices after discharge. Since beta2-agonists do not possess anti-inflammatory activity in vivo, and are thus unlikely to influence the rate of recovery from an asthma exacerbation, it was hypothesized that patients given the short-acting beta2-agonist salbutamol on an as-required basis after admission to hospital would recover as quickly as those on regular treatment, but with potential reductions in the total dose delivered. Forty-six patients with acute severe asthma were randomly assigned to either regular prescriptions of nebulized salbutamol or to usage on a p.r.n. basis, from 24 h after hospital admission. The primary outcome measures were length of hospital stay, time to recovery, and frequency of salbutamol nebulization from 24 h after admission to discharge. Secondary outcome measures were treatment side-effects (tremor, palpitations), and patient satisfaction. Length of hospital stay was reduced in those patients allocated to p.r.n. salbutamol (geometric mean (GM) 3.7 days) versus regular salbutamol (GM 4.7 days). Time taken for peak expiratory flow to reach 75% of recent best was the same in both groups. There was a highly significant reduction in the number of times nebulized therapy was delivered to the p.r.n. group (GM 7.0, range 1-30) compared with the regular treatment group (GM 14.0, range 4-57; p=0.003; 95% confidence interval for ratio of GMs 1.29-3.09). In addition, patients reported less tremor (p=0.062) and fewer palpitations (p=0.049) in the p.r.n. group. Of the patients in the p.r.n. group who had received regular nebulized therapy on previous admissions (n=12), all preferred the p.r.n. regimen. Prescribing beta2-agonists on a p.r.n. basis from 24 h after hospital admission is associated with reduced amount of drug delivered, incidence of side-effects, and possibly length of hospital stay. This has implications for the efficient use of healthcare resources. (+info)
Endoscopic retreatment compared with surgery in patients with recurrent bleeding after initial endoscopic control of bleeding ulcers. (6/7364)BACKGROUND AND METHODS: After endoscopic treatment to control bleeding of peptic ulcers, bleeding recurs in 15 to 20 percent of patients. In a prospective, randomized study, we compared endoscopic retreatment with surgery after initial endoscopy. Over a 40-month period, 1169 of 3473 adults who were admitted to our hospital with bleeding peptic ulcers underwent endoscopy to reestablish hemostasis. Of 100 patients with recurrent bleeding, 7 patients with cancer and 1 patient with cardiac arrest were excluded from the study; 48 patients were randomly assigned to undergo immediate endoscopic retreatment and 44 were assigned to undergo surgery. The type of operation used was left to the surgeon. Bleeding was considered to have recurred in the event of any one of the following: vomiting of fresh blood, hypotension and melena, or a requirement for more than four units of blood in the 72-hour period after endoscopic treatment. RESULTS: Of the 48 patients who were assigned to endoscopic retreatment, 35 had long-term control of bleeding. Thirteen underwent salvage surgery, 11 because retreatment failed and 2 because of perforations resulting from thermocoagulation. Five patients in the endoscopy group died within 30 days, as compared with eight patients in the surgery group (P=0.37). Seven patients in the endoscopy group (including 6 who underwent salvage surgery) had complications, as compared with 16 in the surgery group (P=0.03). The duration of hospitalization, the need for hospitalization in the intensive care unit and the resultant duration of that stay, and the number of blood transfusions were similar in the two groups. In multivariate analysis, hypotension at randomization (P=0.01) and an ulcer size of at least 2 cm (P=0.03) were independent factors predictive of the failure of endoscopic retreatment. CONCLUSIONS: In patients with peptic ulcers and recurrent bleeding after initial endoscopic control of bleeding, endoscopic retreatment reduces the need for surgery without increasing the risk of death and is associated with fewer complications than is surgery.

Hematocrit level and associated mortality in hemodialysis patients. (7/7364)Although a number of clinical studies have shown that increased hematocrits are associated with improved outcomes in terms of cognitive function, reduced left ventricular hypertrophy, increased exercise tolerance, and improved quality of life, the optimal hematocrit level associated with survival has yet to be determined. The association between hematocrit levels and patient mortality was retrospectively studied in a prevalent Medicare hemodialysis cohort on a national scale. All patients survived a 6-mo entry period during which their hematocrit levels were assessed, from July 1 through December 31, 1993, with follow-up from January 1 through December 31, 1994. Patient comorbid conditions relative to clinical events and severity of disease were determined from Medicare claims data and correlated with the entry period hematocrit level. After adjusting for medical diseases, our results showed that patients with hematocrit levels less than 30% had significantly higher risk of all-cause (12 to 33%) and cause-specific death, compared to patients with hematocrits in the 30% to less than 33% range. Without severity of disease adjustment, patients with hematocrit levels of 33% to less than 36% appear to have the lowest risk for all-cause and cardiac mortality. After adjusting for severity of disease, the impact of hematocrit levels of 33% to less than 36% is vulnerable to the patient sample size but also demonstrates a further 4% reduced risk of death. Overall, these findings suggest that sustained increases in hematocrit levels are associated with improved patient survival. (+info)
Minimally invasive aortic valve replacement through a transverse sternotomy: a word of caution. (8/7364)OBJECTIVES: To compare aortic valve replacement (AVR) using a minimally invasive approach through a transverse sternotomy with the established approach of median sternotomy. DESIGN: Retrospective, case-control study. PATIENTS: Fourteen high risk patients (median age 78, Parsonnet score of 18%) who underwent AVR performed through a minimally invasive transverse sternotomy were compared with a historical group of patients matched for age, sex, and Parsonnet score who underwent AVR performed through a median sternotomy by the same surgeon. OUTCOME MEASURES: Cross clamp time, total bypass time, intensive care stay, postoperative in-hospital stay, morbidity, and mortality. RESULTS: There were two deaths in the minimally invasive group and none in the control group (NS). The cross clamp and total bypass times were longer in the minimally invasive group (67 and 92 minutes v 46 and 66 minutes, p < 0.001). There was a higher incidence of re-exploration for bleeding (14% v 0%) and paravalvar leaks (21% v 0%) in the minimally invasive group but these differences were not significant. The minimally invasive group had a longer postoperative in-hospital stay (p = 0.025). The incidence of mortality or major morbidity was 43% (six of 14) in the minimally invasive group and 7% (one of 14) in the matched pairs (p = 0.013). CONCLUSIONS: AVR can be performed through a transverse sternotomy but the operation takes longer and there is an unacceptably high incidence of morbidity and mortality. (+info)
Postoperative complications are adverse events that occur after a surgical procedure. They can range from minor issues, such as bruising or discomfort, to more serious problems, such as infection, bleeding, or organ damage. Postoperative complications can occur for a variety of reasons, including surgical errors, anesthesia errors, infections, allergic reactions to medications, and underlying medical conditions. They can also be caused by factors such as poor nutrition, dehydration, and smoking. Postoperative complications can have serious consequences for patients, including prolonged hospital stays, additional surgeries, and even death. Therefore, it is important for healthcare providers to take steps to prevent postoperative complications and to promptly recognize and treat them if they do occur.
In the medical field, a base sequence refers to the specific order of nucleotides (adenine, thymine, cytosine, and guanine) that make up the genetic material (DNA or RNA) of an organism. The base sequence determines the genetic information encoded within the DNA molecule and ultimately determines the traits and characteristics of an individual. The base sequence can be analyzed using various techniques, such as DNA sequencing, to identify genetic variations or mutations that may be associated with certain diseases or conditions.
Axial length, eye refers to the distance between the front surface of the cornea and the back surface of the lens in the human eye. It is an important measurement in the field of ophthalmology and is used to diagnose and treat various eye conditions such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The axial length of the eye can be measured using various techniques such as ultrasound, optical coherence tomography (OCT), and biometry. An accurate measurement of the axial length is crucial for determining the appropriate prescription for corrective lenses or for surgical procedures such as laser eye surgery.
In the medical field, critical pathways are a set of guidelines or protocols that outline the most effective and efficient sequence of care for a specific medical condition or procedure. These pathways are designed to ensure that patients receive the appropriate care at the right time, in the right place, and by the right provider. Critical pathways typically include a series of steps or tasks that need to be completed in a specific order, along with specific time frames for each task. They may also include decision-making tools or algorithms to help healthcare providers determine the best course of action for a particular patient. The goal of critical pathways is to improve patient outcomes, reduce healthcare costs, and standardize care across different healthcare settings. By following a critical pathway, healthcare providers can ensure that patients receive consistent, high-quality care that is tailored to their individual needs and circumstances.
Amplified Fragment Length Polymorphism Analysis (AFLP) is a molecular genetic technique used to identify and analyze genetic variations in DNA. It involves the amplification of specific DNA fragments using a combination of restriction enzymes and polymerase chain reaction (PCR), followed by separation of the resulting DNA fragments on a gel and visualization of the resulting banding patterns. In the medical field, AFLP analysis is used to study genetic variations in populations, identify genetic markers associated with specific diseases or traits, and investigate the genetic basis of complex disorders. It can also be used to monitor genetic changes in cancer cells over time, and to identify genetic differences between individuals or populations. Overall, AFLP analysis is a powerful tool for genetic research and has a wide range of applications in the medical field.
In the medical field, an amino acid sequence refers to the linear order of amino acids in a protein molecule. Proteins are made up of chains of amino acids, and the specific sequence of these amino acids determines the protein's structure and function. The amino acid sequence is determined by the genetic code, which is a set of rules that specifies how the sequence of nucleotides in DNA is translated into the sequence of amino acids in a protein. Each amino acid is represented by a three-letter code, and the sequence of these codes is the amino acid sequence of the protein. The amino acid sequence is important because it determines the protein's three-dimensional structure, which in turn determines its function. Small changes in the amino acid sequence can have significant effects on the protein's structure and function, and this can lead to diseases or disorders. For example, mutations in the amino acid sequence of a protein involved in blood clotting can lead to bleeding disorders.
Critical illness refers to a severe and potentially life-threatening medical condition that requires immediate medical attention and hospitalization. These conditions can be acute or chronic and can affect any part of the body. Examples of critical illnesses include heart attacks, strokes, organ failure, sepsis, and severe infections. Critical illnesses can be caused by a variety of factors, including genetics, lifestyle choices, and environmental factors. They can also be triggered by other medical conditions or treatments. Treatment for critical illnesses typically involves hospitalization, intensive medical care, and sometimes surgery. In some cases, long-term rehabilitation and ongoing medical care may be necessary. Critical illnesses can have a significant impact on a person's physical and emotional well-being, as well as their ability to work and participate in daily activities. It is important for individuals to have access to appropriate medical care and support to help manage their condition and improve their quality of life.
Cohort studies are a type of observational study in the medical field that involves following a group of individuals (a cohort) over time to identify the incidence of a particular disease or health outcome. The individuals in the cohort are typically selected based on a common characteristic, such as age, gender, or exposure to a particular risk factor. During the study, researchers collect data on the health and lifestyle of the cohort members, and then compare the incidence of the disease or health outcome between different subgroups within the cohort. This can help researchers identify risk factors or protective factors associated with the disease or outcome. Cohort studies are useful for studying the long-term effects of exposure to a particular risk factor, such as smoking or air pollution, on the development of a disease. They can also be used to evaluate the effectiveness of interventions or treatments for a particular disease. One of the main advantages of cohort studies is that they can provide strong evidence of causality, as the exposure and outcome are measured over a long period of time and in the same group of individuals. However, they can be expensive and time-consuming to conduct, and may be subject to biases if the cohort is not representative of the general population.
In the medical field, "age factors" refer to the effects of aging on the body and its various systems. As people age, their bodies undergo a variety of changes that can impact their health and well-being. These changes can include: 1. Decreased immune function: As people age, their immune system becomes less effective at fighting off infections and diseases. 2. Changes in metabolism: Aging can cause changes in the way the body processes food and uses energy, which can lead to weight gain, insulin resistance, and other metabolic disorders. 3. Cardiovascular changes: Aging can lead to changes in the heart and blood vessels, including increased risk of heart disease, stroke, and high blood pressure. 4. Cognitive changes: Aging can affect memory, attention, and other cognitive functions, which can lead to conditions such as dementia and Alzheimer's disease. 5. Joint and bone changes: Aging can cause changes in the joints and bones, including decreased bone density and increased risk of osteoporosis and arthritis. 6. Skin changes: Aging can cause changes in the skin, including wrinkles, age spots, and decreased elasticity. 7. Hormonal changes: Aging can cause changes in hormone levels, including decreased estrogen in women and decreased testosterone in men, which can lead to a variety of health issues. Overall, age factors play a significant role in the development of many health conditions and can impact a person's quality of life. It is important for individuals to be aware of these changes and to take steps to maintain their health and well-being as they age.
DNA, or deoxyribonucleic acid, is a molecule that carries genetic information in living organisms. It is composed of four types of nitrogen-containing molecules called nucleotides, which are arranged in a specific sequence to form the genetic code. In the medical field, DNA is often studied as a tool for understanding and diagnosing genetic disorders. Genetic disorders are caused by changes in the DNA sequence that can affect the function of genes, leading to a variety of health problems. By analyzing DNA, doctors and researchers can identify specific genetic mutations that may be responsible for a particular disorder, and develop targeted treatments or therapies to address the underlying cause of the condition. DNA is also used in forensic science to identify individuals based on their unique genetic fingerprint. This is because each person's DNA sequence is unique, and can be used to distinguish one individual from another. DNA analysis is also used in criminal investigations to help solve crimes by linking DNA evidence to suspects or victims.
In the medical field, the chi-square distribution is a statistical tool used to analyze the relationship between two categorical variables. It is often used in medical research to determine whether there is a significant association between two variables, such as the presence of a disease and a particular risk factor. The chi-square distribution is a probability distribution that describes the sum of the squared differences between the observed and expected frequencies of a categorical variable. It is commonly used in hypothesis testing to determine whether the observed frequencies of a categorical variable differ significantly from the expected frequencies. In medical research, the chi-square test is often used to analyze the relationship between two categorical variables, such as the presence of a disease and a particular risk factor. For example, a researcher may want to determine whether there is a significant association between smoking and lung cancer. To do this, the researcher would collect data on the smoking habits of a group of people and their incidence of lung cancer. The chi-square test would then be used to determine whether the observed frequencies of lung cancer among smokers differ significantly from the expected frequencies based on the overall incidence of lung cancer in the population. Overall, the chi-square distribution is a valuable tool in medical research for analyzing the relationship between categorical variables and determining whether observed frequencies differ significantly from expected frequencies.
Cardiac surgical procedures refer to a range of surgical techniques used to treat various heart conditions. These procedures are typically performed by cardiothoracic surgeons and may involve the use of minimally invasive techniques or open surgery. Some common cardiac surgical procedures include: 1. Coronary artery bypass surgery: This procedure involves using a healthy blood vessel from another part of the body to bypass a blocked or narrowed coronary artery, which can improve blood flow to the heart muscle. 2. Valve replacement or repair: This procedure involves replacing or repairing damaged heart valves, which can improve blood flow through the heart. 3. Heart transplant: This procedure involves replacing a damaged or diseased heart with a healthy heart from a donor. 4. Ablation: This procedure involves using heat, cold, or radiofrequency energy to destroy abnormal heart tissue that is causing irregular heart rhythms. 5. Maze procedure: This procedure involves creating a series of small cuts in the heart to create a maze-like pattern that can help prevent abnormal heart rhythms. 6. Heart bypass surgery: This procedure involves using a healthy blood vessel from another part of the body to bypass a blocked or narrowed coronary artery, which can improve blood flow to the heart muscle. These procedures are typically performed under general anesthesia and may require a hospital stay of several days or more. The specific procedure and recovery time will depend on the individual patient's condition and the type of surgery performed.
Cervical length measurement is a medical procedure used to assess the length of the cervix in pregnant women. The cervix is the lower part of the uterus that connects to the vagina. During pregnancy, the cervix begins to thicken and shorten in preparation for labor. However, in some cases, the cervix may begin to dilate and efface (thin out) too early, which can lead to preterm labor and delivery. Cervical length measurement is typically performed using a transvaginal ultrasound, which involves inserting a small probe into the vagina to visualize the cervix and measure its length. The measurement is usually taken between 18 and 24 weeks of pregnancy, although it may be done earlier if there is a history of preterm labor or other risk factors. A shorter cervix is generally considered to be a risk factor for preterm labor and delivery. Women with a cervix measuring less than 25 millimeters (mm) are at increased risk of preterm labor, and those with a cervix measuring less than 20 mm are at very high risk. In some cases, a cervical cerclage may be recommended to help prevent preterm labor in women with a short cervix.
Biomechanical phenomena refer to the study of the mechanical properties and behavior of living organisms, particularly in relation to movement and function. In the medical field, biomechanical phenomena are often studied in the context of musculoskeletal disorders, sports injuries, and rehabilitation. This involves analyzing the forces and movements involved in various activities, such as walking, running, or lifting, and how they affect the body's tissues and structures. Biomechanical engineers and researchers use a variety of techniques, including computer simulations, imaging technologies, and physical measurements, to study biomechanical phenomena and develop new treatments and interventions for a range of medical conditions.
Blood loss during surgery refers to the amount of blood that is lost from the body during a surgical procedure. This can occur due to various reasons, such as damage to blood vessels during the surgery, excessive bleeding from the surgical site, or the use of anticoagulants that increase bleeding. Blood loss during surgery can be a significant concern for both the patient and the surgical team, as it can lead to anemia, hypovolemia (low blood volume), and other complications. To manage blood loss during surgery, the surgical team may use techniques such as suturing or stapling to close blood vessels, applying pressure to the surgical site, or administering blood transfusions or other fluids to replace lost blood. In some cases, excessive blood loss during surgery may require emergency interventions, such as the use of a blood transfusion or the application of a surgical technique called "damage control surgery," which involves temporarily stabilizing the patient and addressing the underlying cause of the bleeding at a later time.
In the medical field, APACHE stands for Acute Physiology and Chronic Health Evaluation. It is a scoring system used to assess the severity of illness and predict the probability of mortality in critically ill patients. The APACHE score takes into account various physiological parameters such as heart rate, respiratory rate, blood pressure, temperature, oxygenation, and laboratory values, as well as patient demographics and comorbidities. The higher the APACHE score, the more severe the illness and the higher the risk of mortality. The APACHE score is commonly used in intensive care units (ICUs) to guide treatment decisions and to evaluate the effectiveness of interventions.
In the medical field, costs and cost analysis refer to the process of determining the expenses associated with providing healthcare services. This includes the costs of medical equipment, supplies, personnel, facilities, and other resources required to provide medical care. Cost analysis involves examining the costs associated with different aspects of healthcare delivery, such as patient care, administrative tasks, and research and development. This information can be used to identify areas where costs can be reduced or optimized, and to make informed decisions about resource allocation and pricing. Cost analysis is important in the medical field because it helps healthcare providers and administrators to understand the financial implications of providing care, and to make decisions that are both effective and efficient. By analyzing costs, healthcare providers can identify opportunities to improve the quality of care while reducing expenses, which can ultimately benefit patients and the healthcare system as a whole.
Surgical wound infection is an infection that occurs in the surgical site after a surgical procedure. It is caused by bacteria, viruses, or fungi that enter the body through the incision or other surgical opening. The infection can cause redness, swelling, pain, warmth, and pus or drainage from the wound. In severe cases, it can lead to fever, chills, and sepsis, which is a life-threatening condition. Surgical wound infections can be prevented by following proper surgical techniques, using antibiotics when necessary, and keeping the wound clean and dry. If a surgical wound infection does occur, it is important to seek medical attention promptly to prevent complications and ensure proper treatment.
In the medical field, cost savings refer to the reduction in expenses or costs associated with providing healthcare services. This can include reducing the cost of medical procedures, medications, and equipment, as well as reducing the length of hospital stays and the number of readmissions. Cost savings can be achieved through a variety of strategies, such as implementing more efficient processes and workflows, using technology to automate tasks, and negotiating lower prices with suppliers and vendors. Additionally, cost savings can be achieved by promoting preventive care and early intervention, which can reduce the need for more expensive treatments later on. Overall, the goal of cost savings in the medical field is to provide high-quality care while minimizing expenses and reducing the financial burden on patients, healthcare providers, and insurance companies.
Cloning, molecular, in the medical field refers to the process of creating identical copies of a specific DNA sequence or gene. This is achieved through a technique called polymerase chain reaction (PCR), which amplifies a specific DNA sequence to produce multiple copies of it. Molecular cloning is commonly used in medical research to study the function of specific genes, to create genetically modified organisms for therapeutic purposes, and to develop new drugs and treatments. It is also used in forensic science to identify individuals based on their DNA. In the context of human cloning, molecular cloning is used to create identical copies of a specific gene or DNA sequence from one individual and insert it into the genome of another individual. This technique has been used to create transgenic animals, but human cloning is currently illegal in many countries due to ethical concerns.
Critical care is a specialized branch of medicine that focuses on the care of patients with life-threatening illnesses or injuries. It involves the use of advanced medical technology and highly skilled medical professionals to provide intensive, around-the-clock care to patients who are critically ill or injured. Critical care is typically provided in a specialized unit within a hospital, such as an intensive care unit (ICU), where patients receive continuous monitoring and treatment by a team of healthcare providers, including doctors, nurses, respiratory therapists, and other specialists. The goal of critical care is to stabilize and treat patients with life-threatening conditions, such as sepsis, respiratory failure, cardiac arrest, or trauma, and to prevent complications that can arise from these conditions. Treatment may include medications, mechanical ventilation, dialysis, and other advanced medical interventions. Critical care is a highly specialized field that requires extensive training and expertise, and is typically only provided by healthcare professionals who have completed specialized training in critical care medicine.
Biometry is the scientific study of the measurement and analysis of biological data, particularly in the context of medical research and clinical practice. It involves the use of statistical and mathematical techniques to analyze and interpret data related to the structure, function, and development of living organisms, including humans. In the medical field, biometry is used to measure various biological parameters, such as body size, shape, and composition, as well as physiological and biochemical markers of health and disease. Biometric data can be collected using a variety of techniques, including imaging, laboratory tests, and physical measurements. Biometry is an important tool in medical research, as it allows researchers to quantify and compare biological variables across different populations and study designs. It is also used in clinical practice to diagnose and monitor diseases, as well as to evaluate the effectiveness of treatments and interventions.
In the medical field, concurrent review refers to the process of having multiple reviewers evaluate a patient's medical record or treatment plan at the same time. This approach is often used to ensure that the patient receives the most appropriate and effective care, and to identify any potential errors or inconsistencies in the treatment plan. Concurrent review can be conducted by a team of healthcare professionals, including physicians, nurses, pharmacists, and other specialists. The team may review the patient's medical history, current medications, lab results, and other relevant information to identify any potential issues or areas for improvement. The goal of concurrent review is to improve the quality of care and patient outcomes by identifying and addressing any potential problems before they become more serious. It can also help to reduce the risk of medical errors and improve communication among healthcare providers.
In the medical field, an acute disease is a condition that develops suddenly and progresses rapidly over a short period of time. Acute diseases are typically characterized by severe symptoms and a high degree of morbidity and mortality. Examples of acute diseases include pneumonia, meningitis, sepsis, and heart attacks. These diseases require prompt medical attention and treatment to prevent complications and improve outcomes. In contrast, chronic diseases are long-term conditions that develop gradually over time and may persist for years or even decades.
Telomerase is an enzyme that is responsible for maintaining the length of telomeres, which are the protective caps at the ends of chromosomes. Telomeres are essential for the proper functioning of chromosomes, as they prevent the loss of genetic information during cell division. In most cells, telomeres shorten with each cell division, eventually leading to cellular senescence or death. However, some cells, such as stem cells and cancer cells, are able to maintain their telomere length through the activity of telomerase. In the medical field, telomerase has been the subject of extensive research due to its potential as a therapeutic target for treating age-related diseases and cancer. For example, activating telomerase in cells has been shown to delay cellular senescence and extend the lifespan of cells in vitro. Additionally, inhibiting telomerase activity has been shown to be effective in treating certain types of cancer, as it can prevent cancer cells from dividing and spreading.
Analysis of Variance (ANOVA) is a statistical method used to compare the means of three or more groups. In the medical field, ANOVA can be used to compare the effectiveness of different treatments, interventions, or medications on a particular outcome or variable of interest. For example, a researcher may want to compare the effectiveness of three different medications for treating a particular disease. They could use ANOVA to compare the mean response (e.g., improvement in symptoms) between the three groups of patients who received each medication. If the results show a significant difference between the groups, it would suggest that one medication is more effective than the others. ANOVA can also be used to compare the means of different groups of patients based on a categorical variable, such as age, gender, or race. For example, a researcher may want to compare the mean blood pressure of patients in different age groups. They could use ANOVA to compare the mean blood pressure between the different age groups and determine if there are significant differences. Overall, ANOVA is a powerful statistical tool that can be used to compare the means of different groups in the medical field, helping researchers to identify which treatments or interventions are most effective and to better understand the factors that influence health outcomes.

An appendectomy is a surgical procedure in which the appendix, a small, finger-like organ attached to the large intestine, is removed. The appendix is located in the lower right side of the abdomen and is normally about 9 cm (3.5 inches) long. It is not essential to the functioning of the body and can become inflamed or infected, a condition known as appendicitis. During an appendectomy, the surgeon makes a small incision in the abdomen and removes the appendix through the incision. The surgeon may use laparoscopic techniques, which involve making several small incisions in the abdomen and using a camera and specialized instruments to perform the surgery. Alternatively, the surgeon may make a larger incision and perform the surgery using traditional open surgery techniques. After the appendix is removed, the incision is closed with stitches or staples. The patient is typically given pain medication and may be discharged from the hospital within a few days. In some cases, the patient may need to stay in the hospital for a longer period of time to recover.
Cholecystectomy, Laparoscopic is a surgical procedure that involves removing the gallbladder through small incisions in the abdomen using a laparoscope. The laparoscope is a thin, tube-like instrument that is inserted through the incisions and equipped with a camera that allows the surgeon to view the inside of the abdomen on a video monitor. The surgeon uses specialized instruments to remove the gallbladder and close the incisions. Laparoscopic cholecystectomy is a minimally invasive procedure that typically results in less pain, a shorter hospital stay, and a faster recovery time compared to traditional open cholecystectomy. It is commonly performed to treat gallstones, inflammation of the gallbladder (cholecystitis), and other conditions that affect the gallbladder.
A colectomy is a surgical procedure in which the colon (large intestine) is removed, either partially or completely. It is typically performed to treat conditions such as cancer, inflammatory bowel disease, diverticulitis, and colon polyps. The procedure may be performed laparoscopically or through a traditional open incision, depending on the patient's individual circumstances and the surgeon's preference. After a colectomy, the remaining healthy parts of the digestive system are reconnected, and the patient will need to adapt to a new diet and lifestyle to manage any changes in digestion and elimination.

Case-control studies are a type of observational study used in the medical field to investigate the relationship between an exposure and an outcome. In a case-control study, researchers identify individuals who have experienced a particular outcome (cases) and compare their exposure history to a group of individuals who have not experienced the outcome (controls). The main goal of a case-control study is to determine whether the exposure was a risk factor for the outcome. To do this, researchers collect information about the exposure history of both the cases and the controls and compare the two groups to see if there is a statistically significant difference in the prevalence of the exposure between the two groups. Case-control studies are often used when the outcome of interest is rare, and it is difficult or unethical to conduct a prospective cohort study. However, because case-control studies rely on retrospective data collection, they are subject to recall bias, where participants may not accurately remember their exposure history. Additionally, because case-control studies only provide information about the association between an exposure and an outcome, they cannot establish causality.
Anti-bacterial agents, also known as antibiotics, are medications that are used to treat bacterial infections. They work by killing or inhibiting the growth of bacteria, thereby preventing the spread of the infection. There are several types of anti-bacterial agents, including: 1.

They are an important tool for ensuring that healthcare providers are providing consistent, evidence-based care to their patients, and can help to improve patient outcomes and reduce the risk of medical errors.
In the medical field, body weight refers to the total mass of an individual's body, typically measured in kilograms (kg) or pounds (lbs). It is an important indicator of overall health and can be used to assess a person's risk for certain health conditions, such as obesity, diabetes, and heart disease. Body weight is calculated by measuring the amount of mass that a person's body contains, which includes all of the organs, tissues, bones, and fluids. It is typically measured using a scale or other weighing device, and can be influenced by factors such as age, gender, genetics, and lifestyle. Body weight can be further categorized into different types, such as body mass index (BMI), which takes into account both a person's weight and height, and waist circumference, which measures the size of a person's waist. These measures can provide additional information about a person's overall health and risk for certain conditions.
DNA restriction enzymes are a class of enzymes that are naturally produced by bacteria and archaea to protect their DNA from foreign invaders. These enzymes recognize specific sequences of DNA and cut the strands at specific points, creating a double-stranded break. This allows the bacteria or archaea to destroy the foreign DNA and prevent it from replicating within their cells. In the medical field, DNA restriction enzymes are commonly used in molecular biology techniques such as DNA cloning, genetic engineering, and DNA fingerprinting. They are also used in the diagnosis and treatment of genetic diseases, as well as in the study of viral infections and cancer. By cutting DNA at specific sites, researchers can manipulate and analyze the genetic material to gain insights into the function and regulation of genes, and to develop new therapies for genetic diseases.
In the medical field, "wounds and injuries" refer to any type of damage or harm that is inflicted on the body, typically as a result of an external force or trauma. This can include cuts, scrapes, bruises, burns, fractures, and other types of physical trauma. Wounds can be classified based on their depth and severity. Superficial wounds only penetrate the outer layer of skin (epidermis) and are typically easy to treat. Deeper wounds, such as lacerations or punctures, can penetrate the dermis or subcutaneous tissue and may require more extensive medical attention. Injuries can also be classified based on their cause. For example, a fall may result in both a wound (such as a cut or bruise) and an injury (such as a broken bone or concussion). Injuries can be further classified based on their location, severity, and potential long-term effects. The treatment of wounds and injuries typically involves cleaning and dressing the affected area, administering pain medication if necessary, and monitoring for signs of infection or other complications. In some cases, more extensive medical treatment may be required, such as surgery or physical therapy.
The cervix uteri, also known as the cervix, is the lower part of the uterus in the female reproductive system. It is a muscular, cone-shaped structure that connects the uterus to the vagina. The cervix is responsible for regulating the flow of menstrual blood and controlling the entry and exit of sperm during sexual intercourse. It also plays a role in childbirth by dilating and effacing to allow the baby to pass through the birth canal. In the medical field, the cervix is often examined during routine gynecological exams and is also a key site for cancer screening and treatment.
Postoperative hemorrhage refers to the excessive bleeding that occurs after a surgical procedure. It can occur immediately after surgery or may take several days to develop. Hemorrhage can be classified as either primary or secondary. Primary hemorrhage occurs during the surgical procedure, while secondary hemorrhage occurs after the surgery has been completed. Postoperative hemorrhage can be caused by a variety of factors, including injury to blood vessels during surgery, failure to control bleeding during surgery, and the use of blood-thinning medications. Symptoms of postoperative hemorrhage may include a rapid heart rate, low blood pressure, dizziness, and weakness. Treatment for postoperative hemorrhage may include blood transfusions, medications to stop bleeding, and in severe cases, surgery to repair or remove the source of bleeding. It is important for healthcare providers to closely monitor patients after surgery to detect and treat postoperative hemorrhage promptly to prevent complications and improve outcomes.
In the medical field, aging refers to the natural process of physical, biological, and psychological changes that occur over time in living organisms, including humans. These changes can affect various aspects of an individual's health and well-being, including their metabolism, immune system, cardiovascular system, skeletal system, and cognitive function. Aging is a complex process that is influenced by a combination of genetic, environmental, and lifestyle factors. As people age, their bodies undergo a gradual decline in function, which can lead to the development of age-related diseases and conditions such as arthritis, osteoporosis, cardiovascular disease, diabetes, and dementia. In the medical field, aging is studied in the context of geriatrics, which is the branch of medicine that focuses on the health and well-being of older adults. Geriatricians work to identify and manage age-related health issues, promote healthy aging, and improve the quality of life for older adults.
Blotting, Southern is a laboratory technique used to detect specific DNA sequences in a sample. It is named after Edwin Southern, who developed the technique in the 1970s. The technique involves transferring DNA from a gel onto a membrane, such as nitrocellulose or nylon, and then using labeled probes to detect specific DNA sequences. The blotting process is often used in molecular biology research to study gene expression, genetic variation, and other aspects of DNA biology.
In the medical field, "Child, Hospitalized" refers to a child who is currently being treated as an inpatient in a hospital. This means that the child is staying overnight or for an extended period of time at the hospital to receive medical care and treatment for an illness or injury. Being hospitalized can be a stressful and challenging experience for both the child and their family, as it often involves being away from home and loved ones, receiving medical procedures and treatments, and being surrounded by medical equipment and staff. However, hospitalization is often necessary to provide the child with the necessary medical care and support to recover from their illness or injury. During their hospital stay, the child may receive a range of medical treatments and interventions, such as medication, surgery, physical therapy, or other forms of rehabilitation. The child's hospital stay may also involve regular check-ups and monitoring by medical staff to ensure that their condition is improving and that they are responding well to treatment. Overall, "Child, Hospitalized" is a term used to describe a child who is receiving medical treatment as an inpatient in a hospital, and it highlights the importance of providing specialized care and support to help the child recover and return to good health.
In the medical field, an emergency is a situation that requires immediate medical attention and intervention to prevent serious harm or death. Emergencies can be caused by a variety of factors, including accidents, trauma, illness, or medical conditions that suddenly worsen. Examples of medical emergencies include heart attacks, strokes, severe allergic reactions, respiratory distress, severe bleeding, and traumatic injuries such as broken bones or severe lacerations. In these situations, medical professionals must act quickly to stabilize the patient and provide life-saving treatment. The response to medical emergencies typically involves a team of healthcare providers, including emergency medical technicians (EMTs), paramedics, and doctors, who work together to assess the patient's condition, provide necessary medical interventions, and transport the patient to a hospital for further treatment if necessary.
Cross-sectional studies are a type of observational research design used in the medical field to examine the prevalence or distribution of a particular health outcome or risk factor in a population at a specific point in time. In a cross-sectional study, data is collected from a sample of individuals who are all measured at the same time, rather than following them over time. Cross-sectional studies are useful for identifying associations between health outcomes and risk factors, but they cannot establish causality. For example, a cross-sectional study may find that people who smoke are more likely to have lung cancer than non-smokers, but it cannot determine whether smoking causes lung cancer or if people with lung cancer are more likely to smoke. Cross-sectional studies are often used in public health research to estimate the prevalence of diseases or conditions in a population, to identify risk factors for certain health outcomes, and to compare the health status of different groups of people. They can also be used to evaluate the effectiveness of interventions or to identify potential risk factors for disease outbreaks.
An Academic Medical Center (AMC) is a type of medical institution that combines the functions of a hospital, research center, and medical school. The primary goal of an AMC is to provide high-quality patient care, conduct cutting-edge medical research, and train the next generation of healthcare professionals. AMCs typically have a large number of beds and a wide range of medical specialties, including surgery, medicine, pediatrics, obstetrics and gynecology, and neuroscience. They often have affiliations with universities and medical schools, which allow them to attract top faculty and train medical students, residents, and fellows. In addition to providing patient care and conducting research, AMCs also play a critical role in advancing medical knowledge and improving healthcare outcomes. They often collaborate with other healthcare institutions and organizations to share knowledge and resources, and they may also participate in clinical trials and other research initiatives. Overall, AMCs are important centers of medical innovation and excellence, and they play a vital role in advancing the field of medicine and improving the health and well-being of patients around the world.
Arthroplasty, replacement, hip is a surgical procedure in which the damaged or diseased hip joint is replaced with an artificial joint made of metal, plastic, or ceramic. The procedure is typically performed to relieve pain, improve mobility, and restore function to the hip joint. During the surgery, the damaged or diseased parts of the hip joint, such as the ball and socket, are removed and replaced with artificial components. The artificial joint is then secured in place using screws, pins, or cement. There are several types of hip arthroplasty, including total hip replacement, partial hip replacement, and hip resurfacing. The choice of procedure depends on the severity of the condition, the patient's age and overall health, and other factors. Hip arthroplasty is a common and effective treatment for conditions such as osteoarthritis, hip fractures, and hip dysplasia. However, like any surgical procedure, it carries some risks, including infection, blood clots, and dislocation.
In the medical field, a stroke is a medical emergency that occurs when blood flow to the brain is interrupted or reduced, causing brain cells to die. This can happen in two ways: 1. Ischemic stroke: This is the most common type of stroke, accounting for about 85% of all strokes. It occurs when a blood clot blocks a blood vessel in the brain, cutting off blood flow to the affected area. 2. Hemorrhagic stroke: This type of stroke occurs when a blood vessel in the brain ruptures, causing bleeding into the brain. Hemorrhagic strokes are less common than ischemic strokes, accounting for about 15% of all strokes. Strokes can cause a wide range of symptoms, depending on the location and severity of the brain damage. Common symptoms include sudden weakness or numbness in the face, arm, or leg, especially on one side of the body; difficulty speaking or understanding speech; vision problems; dizziness or loss of balance; and severe headache. Prompt medical treatment is crucial for stroke patients, as the sooner treatment is given, the better the chances of recovery. Treatment options may include medications to dissolve blood clots or prevent further clot formation, surgery to remove a blood clot or repair a ruptured blood vessel, and rehabilitation to help patients recover from the effects of the stroke.
In the medical field, "Brazil" typically refers to the country located in South America. Brazil is the largest country in both South America and Latin America, and it is known for its diverse population, rich culture, and natural resources. In terms of healthcare, Brazil has a publicly funded healthcare system called the Unified Health System (Sistema Único de Saúde, or SUS). The SUS provides free or low-cost healthcare services to all Brazilian citizens and residents, including primary care, hospitalization, and specialized medical care. Brazil has also made significant strides in public health, particularly in the areas of infectious diseases such as HIV/AIDS, tuberculosis, and dengue fever. The country has implemented widespread vaccination programs and has made efforts to improve access to healthcare services in underserved areas. However, Brazil still faces significant challenges in the healthcare sector, including a shortage of healthcare professionals, inadequate infrastructure, and disparities in access to healthcare services between different regions and socioeconomic groups.
In the medical field, "Conversion to Open Surgery" refers to a surgical procedure in which a minimally invasive or laparoscopic surgical approach is converted to an open surgical approach. This may occur when the surgeon encounters unexpected difficulties or complications during the laparoscopic procedure that make it unsafe or impossible to continue with the laparoscopic approach. There are several reasons why a laparoscopic procedure may need to be converted to an open surgical approach. For example, the surgeon may encounter dense adhesions (scar tissue) that make it difficult to visualize or access the surgical site. The surgeon may also encounter a complication such as a perforation (hole) in the abdominal wall or a spillage of abdominal contents that requires immediate attention. Conversion to open surgery typically involves making a larger incision in the abdominal wall to provide better access to the surgical site. The surgeon will then proceed with the open surgical procedure using traditional surgical techniques. Conversion to open surgery can be a challenging and time-consuming procedure, and it may result in a longer recovery time and increased risk of complications compared to laparoscopic surgery. However, in some cases, conversion to open surgery may be necessary to ensure the safety and well-being of the patient.
