The color fresco Care of The Sick by Domenico di Bartolo, 1441–1442, depicting the Santa Maria della Scala hospital in Siena, Italy
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of creativity and skill), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism. In recent centuries, since the advent of modern science, most medicine has become a combination of art and science (both basic and applied, under the umbrella of medical science). For example, while stitching technique for sutures is an art learned through practice, knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science.
Prescientific forms of medicine, now known as traditional medicine or folk medicine, remain commonly used in the absence of scientific medicine and are thus called alternative medicine. Alternative treatments outside of scientific medicine with ethical, safety and efficacy concerns are termed quackery. (Full article...)

Amphetamine (contracted from alpha-methylphenethylamine) is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity. Amphetamine was discovered as a chemical in 1887 by Lazăr Edeleanu, and then as a drug in the late 1920s. It exists as two enantiomers: levoamphetamine and dextroamphetamine. Amphetamine properly refers to a specific chemical, the racemic free base, which is equal parts of the two enantiomers in their pure amine forms. The term is frequently used informally to refer to any combination of the enantiomers, or to either of them alone. Historically, it has been used to treat nasal congestion and depression. Amphetamine is also used as an athletic performance enhancer and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant. It is a prescription drug in many countries, and unauthorized possession and distribution of amphetamine are often tightly controlled due to the significant health risks associated with recreational use.
The first amphetamine pharmaceutical was Benzedrine, a brand which was used to treat a variety of conditions. Currently, pharmaceutical amphetamine is prescribed as racemic amphetamine, Adderall, dextroamphetamine, or the inactive prodrug lisdexamfetamine. Amphetamine increases monoamine and excitatory neurotransmission in the brain, with its most pronounced effects targeting the norepinephrine and dopamine neurotransmitter systems. (Full article...)
Rhabdomyolysis (shortened as rhabdo) is a condition in which damaged skeletal muscle breaks down rapidly. Symptoms may include muscle pains, weakness, vomiting, and confusion. There may be tea-colored urine or an irregular heartbeat. Some of the muscle breakdown products, such as the protein myoglobin, are harmful to the kidneys and can cause acute kidney injury.
The muscle damage is most usually caused by a crush injury, strenuous exercise, medications, or a substance use disorder. Other causes include infections, electrical injury, heat stroke, prolonged immobilization, lack of blood flow to a limb, or snake bites as well as intense or prolonged exercise, particularly in hot conditions. Statins (prescription drugs to lower cholesterol) are considered a small risk. Some people have inherited muscle conditions that increase the risk of rhabdomyolysis. The diagnosis is supported by a urine test strip which is positive for "blood" but the urine contains no red blood cells when examined with a microscope. Blood tests show a creatine kinase activity greater than 1,000 U/L, with severe disease being above 5,000-15,000 U/L. (Full article...)
Bupropion, sold under the brand name Wellbutrin among others, is an atypical antidepressant primarily used to treat major depressive disorder and to support smoking cessation. It is also popular as an add-on medication in the cases of "incomplete response" to the first-line selective serotonin reuptake inhibitor (SSRI) antidepressant. Bupropion has several features that distinguish it from other antidepressants: it does not usually cause sexual dysfunction, it is not associated with weight gain and sleepiness, and it is more effective than SSRIs at improving symptoms of hypersomnia and fatigue. Bupropion, particularly the immediate release formulation, carries a higher risk of seizure than many other antidepressants, hence caution is recommended in patients with a history of seizure disorder.
Common adverse effects of bupropion with the greatest difference from placebo are dry mouth, nausea, constipation, insomnia, anxiety, tremor, and excessive sweating. Raised blood pressure is notable. Rare but serious side effects include seizure, liver toxicity, psychosis, and risk of overdose. Bupropion use during pregnancy may be associated with increased odds of congenital heart defects.

Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive low mood, low self-esteem, and loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this symptom cluster under mood disorders in the 1980 version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), and has become widely used since.
The diagnosis of major depressive disorder is based on the person's reported experiences, behavior reported by relatives or friends, and a mental status examination. There is no laboratory test for the disorder, but testing may be done to rule out physical conditions that can cause similar symptoms. The most common time of onset is in a person's 20s, with females affected about twice as often as males. The course of the disorder varies widely, from one episode lasting months to a lifelong disorder with recurrent major depressive episodes. (Full article...)
Cholangiocarcinoma, also known as bile duct cancer, is a type of cancer that forms in the bile ducts. Symptoms of cholangiocarcinoma may include abdominal pain, yellowish skin, weight loss, generalized itching, and fever. Light colored stool or dark urine may also occur. Other biliary tract cancers include gallbladder cancer and cancer of the ampulla of Vater.
Risk factors for cholangiocarcinoma include primary sclerosing cholangitis (an inflammatory disease of the bile ducts), ulcerative colitis, cirrhosis, hepatitis C, hepatitis B, infection with certain liver flukes, and some congenital liver malformations. However, most people have no identifiable risk factors. The diagnosis is suspected based on a combination of blood tests, medical imaging, endoscopy, and sometimes surgical exploration. The disease is confirmed by examination of cells from the tumor under a microscope. It is typically an adenocarcinoma (a cancer that forms glands or secretes mucin). (Full article...)
Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 75% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection.
Polio occurs naturally only in humans. It is highly infectious, and is spread from person to person either through fecal–oral transmission (e.g. poor hygiene, or by ingestion of food or water contaminated by human feces), or via the oral–oral route. Those who are infected may spread the disease for up to six weeks even if no symptoms are present. The disease may be diagnosed by finding the virus in the feces or detecting antibodies against it in the blood.

Dealing with anthropodermic bibliopegy, the binding of books in human skin, it expounds upon Rosenbloom's research on such books and their historical, ethical, and cultural implications.
The book focuses on the relationship between anthropodermic bibliopegy and the history of medicine; most confirmed cases of such books were created or owned by medical professionals, in contrast to common stereotypes that they were associated with Nazi Germany, serial killers, or the French Revolution. Rosenbloom discusses how the practice reflects the changing attitudes towards consent, ownership, and disposal of human bodies, and how the history of anthropodermic books intertwines with the history of medical ethics as a field. She interviews librarians, archivists, collectors, and experts on the topic, and examines notable examples of such books and their origins. Though Rosenbloom supports the preservation and maintenance of anthropodermic books, Dark Archives also covers arguments to the contrary, such as those espoused by Princeton University Library senior librarian Paul Needham.

Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. Symptoms may include a severe headache of rapid onset, vomiting, decreased level of consciousness, fever, weakness, numbness, and sometimes seizures. Neck stiffness or neck pain are also relatively common. In about a quarter of people a small bleed with resolving symptoms occurs within a month of a larger bleed.
SAH may occur as a result of a head injury or spontaneously, usually from a ruptured cerebral aneurysm. Risk factors for spontaneous cases include high blood pressure, smoking, family history, alcoholism, and cocaine use. Generally, the diagnosis can be determined by a CT scan of the head if done within six hours of symptom onset. Occasionally, a lumbar puncture is also required. After confirmation further tests are usually performed to determine the underlying cause. (Full article...)
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 11,000 of the millions of virus species have been described in detail. The study of viruses is known as virology, a subspeciality of microbiology.
When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent viral particles, or virions, consisting of (i) genetic material, i.e., long molecules of DNA or RNA that encode the structure of the proteins by which the virus acts; (ii) a protein coat, the capsid, which surrounds and protects the genetic material; and in some cases (iii) an outside envelope of lipids. The shapes of these virus particles range from simple helical and icosahedral forms to more complex structures. Most virus species have virions too small to be seen with an optical microscope and are one-hundredth the size of most bacteria. (Full article...)
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA). The main uses are infections of the skin and pneumonia although it may be used for a variety of other infections including drug-resistant tuberculosis. It is used either by injection into a vein or by mouth.
When given for short periods, linezolid is a relatively safe antibiotic. It can be used in people of all ages and in people with liver disease or poor kidney function. Common side effects with short-term use include headache, diarrhea, rash, and nausea. Serious side effects may include serotonin syndrome, bone marrow suppression, and high blood lactate levels, particularly when used for more than two weeks. If used for longer periods it may cause nerve damage, including optic nerve damage, which may be irreversible. (Full article...)- Genetics is the study of genes, genetic variation, and heredity in organisms. It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.
Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the context of a population. Genetics has given rise to a number of subfields, including molecular genetics, epigenetics and population genetics. Organisms studied within the broad field span the domains of life (archaea, bacteria, and eukarya). (Full article...)
Influenza, commonly known as "the flu" or just "flu", is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin from one to four days after exposure to the virus (typically two days) and last for about 2–8 days. Diarrhea and vomiting can occur, particularly in children. Influenza may progress to pneumonia, which can be caused by the virus or by a subsequent bacterial infection. Other complications of infection include acute respiratory distress syndrome, meningitis, encephalitis, and worsening of pre-existing health problems such as asthma and cardiovascular disease.
There are four types of influenza virus: A, B, C, and D. Aquatic birds are the primary source of Influenza A virus (IAV), which is also widespread in various mammals, including humans and pigs. Influenza B virus (IBV) and Influenza C virus (ICV) primarily infect humans, and Influenza D virus (IDV) is found in cattle and pigs. IAV and IBV circulate in humans and cause seasonal epidemics, and ICV causes a mild infection, primarily in children. IDV can infect humans but is not known to cause illness. In humans, influenza viruses are primarily transmitted through respiratory droplets produced from coughing and sneezing. Transmission through aerosols and intermediate objects and surfaces contaminated by the virus also occur. (Full article...)
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels.
The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, Hirudo medicinalis, are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from clotting. The jaws used to pierce the skin are replaced in other species by a proboscis which is pushed into the skin. A minority of leech species are predatory, mostly preying on small invertebrates.

Menstrual cycle
The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the uterus (womb) to receive an embryo. These cycles are concurrent and coordinated, normally last between 21 and 35 days, with a median length of 28 days, and continue for about 30–45 years.
Naturally occurring hormones drive the cycles; the cyclical rise and fall of the follicle stimulating hormone prompts the production and growth of oocytes (immature egg cells). The hormone estrogen stimulates the uterus lining (endometrium) to thicken to accommodate an embryo should fertilization occur. The blood supply of the thickened lining provides nutrients to a successfully implanted embryo. If implantation does not occur, the lining breaks down and blood is released. Triggered by falling progesterone levels, menstruation (a "period", in common parlance) is the cyclical shedding of the lining, and is a sign that pregnancy has not occurred.

He was killed during the Battle of Attu on Attu Island, Alaska, United States, on May 30, 1943.
A devout Seventh-day Adventist, Tatsuguchi studied medicine and was licensed as a physician in the United States (US). He returned to his native Japan to practice medicine at the Tokyo Adventist Sanitarium, where he received further medical training. In 1941, he was ordered to cease his medical practice and conscripted into the IJA as an acting medical officer, although he was given an enlisted rather than officer rank because of his American connections. In late 1942, Tatsuguchi was sent to Attu, which had been occupied by Japanese forces in June 1942. On May 11, 1943, The United States Army landed on the island, intending to retake American soil from the Japanese. (Full article...)

Meth mouth is a colloquial term used to describe severe tooth decay and tooth loss, as well as tooth fracture, acid erosion, and other oral problems that are often symptomatic to extended use of the drug methamphetamine. The condition is thought to be caused by a combination of side effects of the drug (clenching and grinding of teeth, dry mouth) and lifestyle factors (infrequent oral hygiene, frequent consumption of sugary drinks, as well as neglecting regular dental cleanings and preventive care), which may be present in long-term users. However, the legitimacy of meth mouth as a unique condition has been questioned because of the similar effects of some other drugs on teeth. Images of diseased mouths are often used in anti-drug campaigns.
The condition is difficult to treat, and may involve fillings, fluoride to fight tooth decay and drugs that increase saliva for dry mouth, as well as oral hygiene instruction. It can be dangerous for active methamphetamine users to undergo
dental surgery because of the cardiac problems that can result from the interaction of local anesthetic with the drug. (Full article...)-Pantothenic_acid_Formula_V.1.svg.png.webp)
Pantothenic acid (vitamin B5) is a B vitamin and an essential nutrient. All animals need pantothenic acid in order to synthesize coenzyme A (CoA)—essential for metabolizing fatty acid—and to synthesize and metabolize proteins, carbohydrates, and fats.
Pantothenic acid is the combination of pantoic acid and β-alanine. Its name comes from the Greek πάντοθεν pantothen, meaning "from everywhere", because pantothenic acid, at least in small amounts, is in almost all foods. Deficiency of pantothenic acid is very rare in humans. In dietary supplements and animal feed, the form commonly used is calcium pantothenate, because chemically it is more stable, and hence makes for longer product shelf-life, than sodium pantothenate and free pantothenic acid.

Malaria is a mosquito-borne infectious disease that affects humans and other vertebrates. Human malaria causes symptoms that typically include fever, fatigue, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin 10 to 15 days after being bitten by an infected Anopheles mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria.
Human malaria is caused by single-celled microorganisms of the Plasmodium group. It is spread exclusively through bites of infected female Anopheles mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of Plasmodium can infect and be spread by humans. Most deaths are caused by P. falciparum, whereas P. vivax, P. ovale, and P. malariae generally cause a milder form of malaria. The species P. knowlesi rarely causes disease in humans. Malaria is typically diagnosed by the microscopic examination of blood using blood films, or with antigen-based rapid diagnostic tests. Methods that use the polymerase chain reaction to detect the parasite's DNA have been developed, but they are not widely used in areas where malaria is common, due to their cost and complexity.

Beck, is a 21-question multiple-choice self-report inventory, one of the most widely used psychometric tests for measuring the severity of depression. Its development marked a shift among mental health professionals, who had until then, viewed depression from a psychodynamic perspective, instead of it being rooted in the patient's own thoughts.
In its current version, the BDI-II is designed for individuals aged 13 and over, and is composed of items relating to symptoms of depression such as hopelessness and irritability, cognitions such as guilt or feelings of being punished, as well as physical symptoms such as fatigue, weight loss, and lack of interest in sex.

17q12 microdeletion syndrome, also known as 17q12 deletion syndrome, is a rare chromosomal anomaly caused by the deletion of a small amount of material from a region in the long arm of chromosome 17. It is typified by deletion of the HNF1B gene, resulting in kidney abnormalities and renal cysts and diabetes syndrome. It also has neurocognitive effects, and has been implicated as a genetic factor for autism and schizophrenia.
17q12 microdeletion syndrome is not to be confused with 17q12 microduplication syndrome, caused by the addition of genetic material in the same region from which it is removed in the microdeletion, or 17q21.31 microdeletion syndrome, another name for Koolen–De Vries syndrome. (Full article...)
Hypopituitarism is the decreased (hypo) secretion of one or more of the eight hormones normally produced by the pituitary gland at the base of the brain. If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. If there is decreased secretion of most or all pituitary hormones, the term panhypopituitarism (pan meaning "all") is used.
The signs and symptoms of hypopituitarism vary, depending on which hormones are undersecreted and on the underlying cause of the abnormality. The diagnosis of hypopituitarism is made by blood tests, but often specific scans and other investigations are needed to find the underlying cause, such as tumors of the pituitary, and the ideal treatment. Most hormones controlled by the secretions of the pituitary can be replaced by tablets or injections. Hypopituitarism is a rare disease, but may be significantly underdiagnosed in people with previous traumatic brain injury. The first description of the condition was made in 1914 by the German physician Dr Morris Simmonds. (Full article...)
A Book of Medical Discourses (1883) by Rebecca Lee Crumpler, M.D.
Rebecca Lee Crumpler, born Rebecca Davis, (February 8, 1831 – March 9, 1895), was an American physician, nurse and author. After studying at the New England Female Medical College, in 1864 she became the first African American woman to become a doctor of medicine in the United States. Crumpler was also one of the first female physician authors in the nineteenth century. In 1883, she published A Book of Medical Discourses. The book has two parts that cover the prevention and cure of infantile bowel complaints, and the life and growth of human beings. Dedicated to nurses and mothers, it focuses on maternal and pediatric medical care and was among the first publications written by an African American on the subject of medicine.
Crumpler graduated from medical college at a time when very few African Americans were permitted to attend medical college or publish books. Crumpler first practiced medicine in Boston, primarily serving poor women and children. After the American Civil War ended in 1865, she moved to Richmond, Virginia, believing treating women and children was an ideal way to perform missionary work. Crumpler worked for the Freedmen's Bureau to provide medical care for freedmen and freedwomen. (Full article...)
Eugene W. Caldwell (1870–1918) was an American engineer, radiographer, and physician who conducted early work on the medical uses of X-rays. A native of Missouri, Caldwell studied engineering at the University of Kansas. After working as an engineer for five years, Caldwell became interested in X-rays in 1897, opening what may have been the first X-ray clinic in New York City. He taught radiography at University and Bellevue Hospital Medical College and later graduated with a medical degree from that institution.
Caldwell was president of the American Roentgen Ray Society (ARRS) in 1907, invented the first portable X-ray machine for use at a patient's bedside, and devised a positioning technique known as Caldwell's view that allowed for X-ray visualization of the sinuses. He also enhanced X-ray technology to reduce the exposure time required to obtain an image, created a stereoscopic device for X-rays so that they could show depth, and modified an existing stereoscopic fluoroscope for wartime use.

Anti-vaccination activists promoting the incorrect claim that vaccination causes autism have asserted that the mercury in thiomersal is the cause. There is no scientific evidence to support this claim. The idea that thiomersal in vaccines might have detrimental effects originated with anti-vaccination activists and was sustained by them and especially through the action of plaintiffs' lawyers.
The potential impact of thiomersal on autism has been investigated extensively. Multiple lines of scientific evidence have shown that thiomersal does not cause autism. For example, the clinical symptoms of mercury poisoning differ significantly from those of autism. In addition, multiple population studies have found no association between thiomersal and autism, and rates of autism have continued to increase despite removal of thiomersal from vaccines. Thus, major scientific and medical bodies such as the Institute of Medicine and World Health Organization (WHO) as well as governmental agencies such as the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) reject any role for thiomersal in autism or other neurodevelopmental disorders. In spite of the consensus of the scientific community, some parents and advocacy groups continue to contend that thiomersal is linked to autism and the claim is still stated as if it were fact in anti-vaccination propaganda, notably that of Robert F. Kennedy Jr., through his group Children's Health Defense. Thiomersal is no longer used in most children's vaccines in the United States, with the exception of some types of flu shots. While exposure to mercury may result in damage to brain, kidneys, and developing fetus, the scientific consensus is that thiomersal has no such effects.

She was the first woman to be appointed Denver's city toxicologist, the first female toxicologist in the Rocky Mountains, and probably the first female forensic pathologist in the United States.
McConnell was raised in Colorado and after studying chemistry she became a high school teacher. She later attended medical school at the University of Colorado Denver, graduating in 1925. She specialized in the fields of toxicology and forensic pathology, which led her to testify in many high-profile criminal cases throughout her career. In addition to working as Denver's city toxicologist, she held positions in multiple hospitals and administrative boards. After battling lifelong health problems, including rheumatic heart disease and a leg amputation, McConnell died in 1975. She was posthumously inducted into the Colorado Women's Hall of Fame.

A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often such pain occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, feeling tired, and decreased level of consciousness. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest.
Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol intake. The complete blockage of a coronary artery caused by a rupture of an atherosclerotic plaque is usually the underlying mechanism of an MI. MIs are less commonly caused by coronary artery spasms, which may be due to cocaine, significant emotional stress (often known as Takotsubo syndrome or broken heart syndrome) and extreme cold, among others. Many tests are helpful to help with diagnosis, including electrocardiograms (ECGs), blood tests and coronary angiography. An ECG, which is a recording of the heart's electrical activity, may confirm an ST elevation MI (STEMI), if ST elevation is present. Commonly used blood tests include troponin and less often creatine kinase MB. (Full article...)- Women's health differs from that of men's health in many unique ways. Women's health is an example of population health, where health is defined by the World Health Organisation as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Often treated as simply women's reproductive health, many groups argue for a broader definition pertaining to the overall health of women, better expressed as "The health of women". These differences are further exacerbated in developing countries where women, whose health includes both their risks and experiences, are further disadvantaged.
While the rates of the leading causes of death, cardiovascular disease, cancer and lung disease, are similar in women and men, women have different experiences. Lung cancer has overtaken all other types of cancer as the leading cause of cancer related death in women, followed by breast cancer, colorectal, ovarian, uterine and cervical cancers. While smoking is the major cause of lung cancer, amongst nonsmoking women the risk of developing cancer is three times greater than among nonsmoking men. Despite this, breast cancer remains the most common cancer in women in developed countries, and is one of the major chronic diseases of women, while cervical cancer remains one of the most common cancers in developing countries, associated with human papilloma virus (HPV), a sexually transmitted infection. HPV vaccine together with screening offers the promise of controlling these diseases. Other important health issues for women include cardiovascular disease, depression, dementia, osteoporosis and anemia.

The volunteer fire department also serves unincorporated areas of Ossining and Mount Pleasant. The fire department has three fire companies, two stations, and four fire engines. Its engines include three pumpers and a tower-ladder; the department also maintains other vehicles, including a heavy rescue vehicle. The Briarcliff Manor Fire Department Ambulance Corps provides emergency medical transport with two ambulances. The fire department is headquartered at the Briarcliff Manor Village Hall, with its other station in Scarborough, on Scarborough Road.
The Briarcliff Steamer Company No. 1 was founded in 1902 by Frederick C. Messinger. He became the first chief of the department, founded February 10, 1903. In 1906, the Briarcliff Fire Company was established. The village's municipal building and first permanent firehouse was built in 1914 in downtown Briarcliff Manor. Seven years later, in 1921, the Scarborough Fire Company was established. From 1930 to 1971, the Archville Fire Department was dissolved into Scarborough's fire company, which expanded its fire protection to Archville. In 1936, the Briarcliff Manor Hook and Ladder Company was formed. For the department's 50th anniversary, the village hosted numerous events, including a parade with twelve fire departments present. In 1963, the Briarcliff Manor Village Hall was constructed, again housing the fire and police departments. In 1974, a replacement firehouse was built for the Scarborough Engine Company. The fire department's 75th anniversary in 1976 drew a parade of 650 firemen from fourteen companies. In 1982, one of the most notable fires took place, in Briarcliff's downtown. The fire lasted three and a half hours and took over a hundred firefighters to control. The department also participated in fighting the Briarcliff Lodge fire in 2003, which demolished the 1902 Walter Law-built hotel. In 2010, Scarborough's firehouse was again replaced, doubling its size.

She was a co-founder of the Réseau Marcel ("Marcel Network") which saved more than 500 Jewish children from death during The Holocaust. Although she was arrested and tortured by the Gestapo, she refused to divulge the locations of the hidden Jewish children and was sent to two concentration camps. After Bergen-Belsen concentration camp was liberated in 1945, Abadi continued her profession as a doctor, with a focus on tuberculosis.
On 29 July 1999, Abadi died by suicide and the Les Enfants et Amis Abadi organisation was created the following year by one of the children she saved. In 2008, a square in Paris was named "Place Moussa et Odette Abadi" as a tribute to the couple's work. On 28 October 2017, the "Square Odette et Moussa Abadi" was inaugurated in Nice in recognition of their work.

She was a member of the Communist Party USA before it was banned and criminalized in the 1950s and was a reporter and writer for the party's publication Western Worker. She is also known for her romantic relationship with J. Robert Oppenheimer, the director of the Manhattan Project's Los Alamos Laboratory during World War II.
The daughter of John Strong Perry Tatlock, a prominent Old English philologist and an expert on Geoffrey Chaucer, Tatlock was a graduate of Vassar College and the Stanford Medical School, where she studied to become a psychiatrist. Tatlock began seeing Oppenheimer in 1936, when she was a graduate student at Stanford and Oppenheimer was a professor of physics at the University of California, Berkeley. As a result of their relationship and her membership of the Communist Party, she was placed under surveillance by the FBI and her phone was tapped. Tatlock experienced clinical depression, and committed suicide on January 4, 1944. (Full article...)
