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 patients, 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...)

  Anti-FGM road sign near Kapchorwa, Uganda, 2004

  
  Female genital mutilation (FGM) (also known as female genital cutting, female genital mutilation/cutting (FGM/C) and female circumcision) is the cutting or removal of some or all of the vulva for non-medical reasons. FGM prevalence varies worldwide, but is majorly present in some countries of Africa, Asia and Middle East, and within their diasporas. As of 2024, UNICEF estimates that worldwide 230 million girls and women (144 million in Africa, 80 million in Asia, 6 million in Middle East, and 1-2 million in other parts of the world) had been subjected to one or more types of FGM.
  
  Typically carried out by a traditional cutter using a blade, FGM is conducted from days after birth to puberty and beyond. In half of the countries for which national statistics are available, most girls are cut before the age of five. Procedures differ according to the country or ethnic group. They include removal of the clitoral hood (type 1-a) and clitoral glans (1-b); removal of the inner labia (2-a); and removal of the inner and outer labia and closure of the vulva (type 3). In this last procedure, known as infibulation, a small hole is left for the passage of urine and menstrual fluid, the vagina is opened for intercourse and opened further for childbirth.

  Dark Archives: A Librarian's Investigation into the Science and History of Books Bound in Human Skin is a 2020 non-fiction book by the medical librarian and death-positive advocate Megan Rosenbloom. 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.

  Electron micrograph of H. pylori possessing multiple flagella (negative staining)

  
  Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium. Mutants can have a rod or curved rod shape that exhibits less virulence. Its helical body (from which the genus name Helicobacter derives) is thought to have evolved to penetrate the mucous lining of the stomach, helped by its flagella, and thereby establish infection. The bacterium was first identified as the causal agent of gastric ulcers in 1983 by Australian physician-scientists Barry Marshall and Robin Warren. In 2005, they were awarded the Nobel Prize in Physiology or Medicine for their discovery.
  
  Infection of the stomach with H. pylori is not the cause of illness itself: over half of the global population is infected, but most individuals are asymptomatic. Persistent colonization with more virulent strains can induce a number of gastric and non-gastric disorders. Gastric disorders due to infection begin with gastritis, or inflammation of the stomach lining. When infection is persistent, the prolonged inflammation will become chronic gastritis. Initially, this will be non-atrophic gastritis, but the damage caused to the stomach lining can bring about the development of atrophic gastritis and ulcers within the stomach itself or the duodenum (the nearest part of the intestine). At this stage, the risk of developing gastric cancer is high. However, the development of a duodenal ulcer confers a comparatively lower risk of cancer. Helicobacter pylori is a class 1 carcinogenic bacteria, and potential cancers include gastric MALT lymphoma and gastric cancer. Infection with H. pylori is responsible for an estimated 89% of all gastric cancers and is linked to the development of 5.5% of all cases cancers worldwide. H. pylori is the only bacterium known to cause cancer. (Full article...)

  Buruli ulcer lesions. Top-left, an early ulcer. Top-right, a larger ulcer across the lower arm and wrist. Bottom, a large ulcer on the thigh.

  
  Buruli ulcer (/bəˈruːli/) is an infectious disease characterized by the development of painless open wounds. The disease is limited to certain areas of the world, most cases occurring in Sub-Saharan Africa and Australia. The first sign of infection is a small painless nodule or area of swelling, typically on the arms or legs. The nodule grows larger over days to weeks, eventually forming an open ulcer. Deep ulcers can cause scarring of muscles and tendons, resulting in permanent disability.
  
  Buruli ulcer is caused by skin infection with bacteria called Mycobacterium ulcerans. The mechanism by which M. ulcerans is transmitted from the environment to humans is not known, but may involve the bite of an aquatic insect or the infection of open wounds. Once in the skin, M. ulcerans grows and releases the toxin mycolactone, which blocks the normal function of cells, resulting in tissue death and immune suppression at the site of the ulcer.

  A serpin (white) with its 'reactive centre loop' (blue) bound to a protease (grey). Once the protease attempts catalysis it will be irreversibly inhibited. (PDB: 1K9O​)

  
  Serpins are a superfamily of proteins with similar structures that were first identified for their protease inhibition activity and are found in all kingdoms of life. The acronym serpin was originally coined because the first serpins to be identified act on chymotrypsin-like serine proteases (serine protease inhibitors). They are notable for their unusual mechanism of action, in which they irreversibly inhibit their target protease by undergoing a large conformational change to disrupt the target's active site. This contrasts with the more common competitive mechanism for protease inhibitors that bind to and block access to the protease active site.
  
  Protease inhibition by serpins controls an array of biological processes, including coagulation and inflammation, and consequently these proteins are the target of medical research. Their unique conformational change also makes them of interest to the structural biology and protein folding research communities. The conformational-change mechanism confers certain advantages, but it also has drawbacks: serpins are vulnerable to mutations that can result in serpinopathies such as protein misfolding and the formation of inactive long-chain polymers. Serpin polymerisation not only reduces the amount of active inhibitor, but also leads to accumulation of the polymers, causing cell death and organ failure. (Full article...)

  Young people with polio receiving physiotherapy in the 1950s

  
  The social history of viruses describes the influence of viruses and viral infections on human history. Epidemics caused by viruses began when human behaviour changed during the Neolithic period, around 12,000 years ago, when humans developed more densely populated agricultural communities. This allowed viruses to spread rapidly and subsequently to become endemic. Viruses of plants and livestock also increased, and as humans became dependent on agriculture and farming, diseases such as potyviruses of potatoes and rinderpest of cattle had devastating consequences.
  
  Smallpox and measles viruses are among the oldest that infect humans. Having evolved from viruses that infected other animals, they first appeared in humans in Europe and North Africa thousands of years ago. The viruses were later carried to the New World by Europeans during the time of the Spanish Conquests, but the indigenous people had no natural resistance to the viruses and millions of them died during epidemics. Influenza pandemics have been recorded since 1580, and they have occurred with increasing frequency in subsequent centuries. The pandemic of 1918–19, in which 40–50 million died in less than a year, was one of the most devastating in history. (Full article...)

  McGill in her laboratory, 1942

  
  Frances Gertrude McGill (November 18, 1882 – January 21, 1959) was a Canadian forensic pathologist, criminologist, bacteriologist, allergologist and allergist. Nicknamed "the Sherlock Holmes of Saskatchewan" for her deductive skills and public fame, McGill influenced the development of forensic pathology in Canadian police work and was internationally noted for her expertise in the subject.
  
  After completing her medical degree at the University of Manitoba in 1915, McGill moved to Saskatchewan, where she was hired first as the provincial bacteriologist and then as the provincial pathologist. She worked extensively with the Royal Canadian Mounted Police (RCMP) and local police forces for more than thirty years, and was instrumental in establishing the first RCMP forensic laboratory. She directed the RCMP laboratory for three years, and trained new RCMP recruits in forensic detection methods. After retiring in 1946, McGill was appointed Honorary Surgeon for the RCMP by the Canadian Minister of Justice, becoming one of the first official female members of the force, and she continued to act as a consultant to the RCMP until her death in 1959.

  Urine from a person with rhabdomyolysis showing the characteristic brown discoloration as a result of myoglobinuria

  
  Rhabdomyolysis (shortened as rhabdo) is a condition in which damaged skeletal muscle breaks down rapidly, often due to high intensity exercise over a short period. 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 1000 U/L, with severe disease being above 5000–15000 U/L. (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...)

  Thyrotoxic periodic paralysis occurs when the thyroid gland releases excessive amounts of thyroxine (thyroid hormone).

  
  Thyrotoxic periodic paralysis (TPP) is a rare condition featuring attacks of muscle weakness in the presence of hyperthyroidism (overactivity of the thyroid gland). Hypokalemia (a decreased potassium level in the blood) is usually present during attacks. The condition may be life-threatening if weakness of the breathing muscles leads to respiratory failure, or if the low potassium levels lead to abnormal heart rhythms. If untreated, it is typically recurrent in nature.
  
  The condition has been linked with genetic mutations in genes that code for certain ion channels that transport electrolytes (sodium and potassium) across cell membranes. The main ones are the L-type calcium channel α1-subunit and potassium inward rectifier 2.6; it is therefore classified as a channelopathy. The abnormality in the channel is thought to lead to shifts of potassium into cells, under conditions of high thyroxine (thyroid hormone) levels, usually with an additional precipitant.

  In the early 20th century, German researchers found additional evidence linking smoking to health harms, which strengthened the anti-tobacco movement in the Weimar Republic and led to a state-supported anti-smoking campaign. Early anti-tobacco movements grew in many nations from the middle of the 19th century. The 1933–1945 anti-tobacco campaigns in Nazi Germany have been widely publicized, although stronger laws than those passed in Germany were passed in some American states, the UK, and elsewhere between 1890 and 1930. After 1941, anti-tobacco campaigns were restricted by the Nazi government.
  
  The German movement was the most powerful anti-smoking movement in the world during the 1930s and early 1940s. However, tobacco control policy was incoherent and ineffective, with uncoordinated and often regional efforts by many actors. Obvious measures were not taken, and existing measures were not enforced. Some Nazi leaders condemned smoking and several of them openly criticized tobacco consumption, but others publicly smoked and denied that it was harmful. (Full article...)

  Holmes, c. 1880s

  
  Oliver Wendell Holmes Sr. (/hoʊmz/; August 29, 1809 – October 7, 1894) was an American physician, poet, and polymath based in Boston. Grouped among the fireside poets, he was acclaimed by his peers as one of the best writers of the day. His most famous prose works are the "Breakfast-Table" series, which began with The Autocrat of the Breakfast-Table (1858). He was also an important medical reformer. In addition to his work as an author and poet, Holmes also served as a physician, professor, lecturer, inventor, and, although he never practiced it, he received formal training in law.
  
  Born in Cambridge, Massachusetts, Holmes was educated at Phillips Academy and Harvard College. After graduating from Harvard in 1829, he briefly studied law before turning to the medical profession. He began writing poetry at an early age; one of his most famous works, "Old Ironsides", was published in 1830 and was influential in the eventual preservation of the USS Constitution. Following training at the prestigious medical schools of Paris, Holmes was granted his Doctor of Medicine degree from Harvard Medical School in 1836. He taught at Dartmouth Medical School before returning to teach at Harvard and, for a time, served as dean there. During his long professorship, he became an advocate for various medical reforms and notably posited the controversial idea that doctors were capable of carrying puerperal fever from patient to patient. Holmes retired from Harvard in 1882 and continued writing poetry, novels and essays until his death in 1894. (Full article...)

  Cartoon in Punch, November 1858

  
  In 1858 a batch of sweets in Bradford, England, was accidentally adulterated with poisonous arsenic trioxide. About five pounds (two kilograms) of sweets were sold to the public, leading to around 20 deaths and over 200 people suffering the effects of arsenic poisoning.
  
  The adulteration of food had been practised in Britain since before the Middle Ages, but from 1800, with increasing urbanisation and the rise in shop-purchased food, adulterants became a growing problem. With the cost of sugar high, replacing it with substitutes was common. For the sweets produced in Bradford, the confectioner was supposed to purchase powdered gypsum, but a mistake at the wholesale chemist meant arsenic was purchased instead. (Full article...)

  Sorrowing Old Man (At Eternity's Gate), an 1890 portrait by Vincent van Gogh

  
  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 disorder causes the second-most years lived with disability, after lower back pain.
  
  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...)

  In Sierra Leone, abortion is a criminal offence. Its abortion law does not specify any grounds for legal abortion. It is unclear whether abortion is permitted to save the life of the mother, as a British judicial decision allowing such abortions is untested in Sierra Leone. Abortion is covered in the country's medical code of ethics, but there is no government training for providers. Prosecution of abortion is uncommon.
  
  Abortion has been illegal since 1861, inheriting a British law. In the 2010s and 2020s, activists, politicians, and international organizations supported proposals to legalise abortion. Religious groups have supported the ban. Sierra Leone ratified the Maputo Protocol in 2015. A bill allowing abortion, first raised in 2010, was approved by Parliament after being introduced by Isata Kabia in 2015. The bill failed as President Ernest Bai Koroma refused to sign it. This law was heavily debated despite a stigma against the subject. In 2022, the government of Julius Maada Bio backed a new reproductive health bill that would lift the abortion ban.

  Allen being given the Medal of Freedom

  
  Beulah Ream Allen (January 26, 1897 – March 17, 1989) was an American nurse, physician, and civilian physician during World War II. After graduating with a nursing degree in 1922, she worked as a supervising nurse and headed the educational department for the LDS Hospital in Salt Lake City. She worked as a hospital inspector for the state of Utah until 1928, when she moved to San Francisco to attend medical school. While earning her degree at the University of California, San Francisco, she worked as a nurse in the Bay Area. Upon her graduation in 1932, she moved to the Philippines, where she opened a medical practice.
  
  During World War II, she volunteered as a civilian surgeon for the United States Army. She was stationed in Baguio and was responsible for the care of nearly 30 soldiers, when the rest of the Army retreated to the Bataan Peninsula. Taken prisoner in 1941, she was held in three internment camps before being liberated. Returning to the United States, she resumed her practice in the Bay Area. She was awarded the Medal of Freedom in 1946. In 1960, she moved her practice to Provo, Utah, where she served as dean of the Brigham Young University College of Nursing until 1964. Allen retired in 1979 and in that year married and relocated to Mesa, Arizona, where she lived until her death in 1989. (Full article...)

  Two disposable injector pens. On the top pen there is a disclaimer that it contains no insulin and is not to be used for treatment of diabetes.

  
  
  An injector pen (also called a medication pen) is a device used for injecting medication under the skin. First introduced in the 1980s, injector pens are designed to make injectable medication easier and more convenient to use, thus increasing patient adherence. The primary difference between injector pens and traditional vial and syringe administration is the easier use of an injector pen by people with low dexterity, poor vision, or who need portability to administer medicine on time. Injector pens also decrease the fear or adversity towards self-injection of medications, which increases the likelihood that a person takes the medication.
  
  Injector pens are commonly used for medications that are injected repeatedly by a person over a relatively short period of time, especially insulin and insulin analogs used in the treatment of diabetes (called insulin pens). Many other medications are also available as injector pens, including other injectable medicines for diabetes, high cholesterol, migraine prevention, and other monoclonal antibodies. Studies have shown injector pens to be at least as effective as vial and syringe administration, and surveys have shown that a vast majority of people would prefer an injector pen over vial and syringe administration if one was available. After a slow uptake in the United States, injector pens have surpassed vial and syringe administration of insulin in type 2 diabetes. (Full article...)

  Obesity hypoventilation syndrome often improves with positive airway pressure treatment administered overnight by a machine such as this device.

  
  Obesity hypoventilation syndrome (OHS) is a condition in which severely overweight people fail to breathe rapidly or deeply enough, resulting in low oxygen levels and high blood carbon dioxide (CO₂) levels. The syndrome is often associated with obstructive sleep apnea (OSA), which causes periods of absent or reduced breathing in sleep, resulting in many partial awakenings during the night and sleepiness during the day. The disease puts strain on the heart, which may lead to heart failure and leg swelling.
  
  
  Obesity hypoventilation syndrome is defined as the combination of obesity and an increased blood carbon dioxide level during the day that is not attributable to another cause of excessively slow or shallow breathing. (Full article...)

  Coutard in 1937

  
  Henri Coutard (27 August 1876 – 16 March 1950) was a French radiation therapist. He is known for his studies of radiation therapy for the treatment of laryngeal cancer and the development of the "protracted-fractional method" of radiation dosing.
  
  Born in Marolles-les-Braults in the French department of Sarthe, Coutard attended medical school at University of Paris and graduated in 1902. He served in the French Army and lived for several years in the Jura Mountains before returning to Paris to study the medical applications of radium. During World War I, he worked in one of the radiological ambulance units overseen by the Polish-French physicist and chemist Marie Curie. He became the chief of the X-ray department at the Radium Institute of the University of Paris in 1919, working closely with Claudius Regaud and other scientists. Coutard's early work demonstrating the efficacy of radiating patients with laryngeal cancer led to the adoption of radiation therapy as a primary course of cancer treatment. The protracted-fractional method consisted of long durations of radiation applied over several weeks. (Full article...)

  María Teresa Ferrari (11 October 1887 – 30 October 1956) was an Argentine educator, physician, and women's rights activist. She was the first female university professor in Latin America and one of the first women allowed to teach medicine. She was a pioneering researcher in women's health, studying the use of radiation therapy rather than surgery for uterine tumors and developing a vaginoscope that revolutionized women's health care in Brazil. She established the first maternity ward and gynecological services at the Hospital Militar Central of Buenos Aires in 1925, which provided the first incubation services in the country.
  
  Born into a wealthy family whose forebears had been involved in ensuring Argentina's independence from Spain, she was not expected to work outside the home. Yet Ferrari not only chose to have a career but also insisted on participating in the male-dominated medical profession. She first earned a teaching diploma and became a school teacher; then, she earned her medical degree in 1911. After completing her residency, she applied to teach at the university level but instead was offered a teaching post at the School of Midwifery. Outraged, she fought for 13 years against the prejudices that prevented her from advancing in her career. In 1927, Ferrari won her fight and was granted a professorship as an alternate. Finally, in 1939, she was awarded a full professorship. (Full article...)

  The Terri Schiavo case was a series of court and legislative actions in the United States from 1998 to 2005, regarding the care of Theresa Marie Schiavo (née Schindler) (/ˈʃaɪvoʊ/; December 3, 1963 – March 31, 2005), a woman in an irreversible persistent vegetative state. Schiavo's husband and legal guardian argued that Schiavo would not have wanted prolonged artificial life support without the prospect of recovery, and, in 1998, he elected to remove her feeding tube. Schiavo's parents disputed her husband's assertions and challenged Schiavo's medical diagnosis, arguing in favor of continuing artificial nutrition and hydration. The highly publicized and prolonged series of legal challenges presented by her parents, which ultimately involved state and federal politicians up to the level of George W. Bush, the then U.S. president, caused a seven-year (1998 to 2005) delay before Schiavo's feeding tube was ultimately removed.
  
  On February 25, 1990, at age 26, Schiavo went into cardiac arrest at her home in St. Petersburg, Florida. She was resuscitated, but had severe brain damage due to lack of oxygen to her brain and was left comatose. After two and a half months without improvement, her diagnosis was changed to that of a persistent vegetative state. For the next two years, doctors attempted occupational therapy, speech therapy, physical therapy and other experimental therapy, hoping to return her to a state of awareness, without success. In 1998, Schiavo's husband Michael Schiavo petitioned the Sixth Circuit Court of Florida to remove her feeding tube pursuant to Florida law. He was opposed by Terri's parents, Robert and Mary Schindler. The court determined that Schiavo would not have wished to continue life-prolonging measures, and on April 24, 2001, her feeding tube was removed for the first time, only to be reinserted several days later. On February 25, 2005, a Pinellas County judge again ordered the removal of Terri Schiavo's feeding tube. Several appeals and federal government intervention followed, which included Bush returning to Washington, D.C., to sign legislation moving the case to the federal courts. After appeals through the federal court system that upheld the original decision to remove the feeding tube, staff at the Pinellas Park hospice facility disconnected the feeding tube on March 18, 2005, and Schiavo died on March 31, 2005.

  A graduate of the University of Melbourne, where she studied medicine and excelled at sports, Mary qualified as a general practitioner in 1921 and became a resident surgeon at Royal Melbourne Hospital. Her work was mainly with poor women, many of whom lived in unsanitary conditions and had inadequate diets. The social mores of the time often kept young women ignorant of matters dealing with sex and pregnancy. She recognised that pregnant women in particular needed more information about what was happening to them, and provided information on birth control at a time when many doctors and a large segment of the community were opposed to it. "She broke taboos", Della Hilton later wrote, and "made forbidden subjects not only matters for discussion, but for action". (Full article...)

  DVT in the right leg with swelling and redness

  
  Deep vein thrombosis (DVT) is a type of venous thrombosis involving the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. A minority of DVTs occur in the arms. Symptoms can include pain, swelling, redness, and enlarged veins in the affected area, but some DVTs have no symptoms.
  
  The most common life-threatening concern with DVT is the potential for a clot to embolize (detach from the veins), travel as an embolus through the right side of the heart, and become lodged in a pulmonary artery that supplies blood to the lungs. This is called a pulmonary embolism (PE). DVT and PE comprise the cardiovascular disease of venous thromboembolism (VTE). (Full article...)

  Iodine is a chemical element; it has symbol I and atomic number 53. The heaviest of the stable halogens, it exists at standard conditions as a semi-lustrous, non-metallic solid that melts to form a deep violet liquid at 114 °C (237 °F), and boils to a violet gas at 184 °C (363 °F). The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek Ιώδης, meaning 'violet'.
  
  Iodine occurs in many oxidation states, including iodide (I⁻), iodate (IO⁻
  ₃), and the various periodate anions. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. (Full article...)

  Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall warming trend, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires, thawing permafrost, and desertification. These changes impact ecosystems and societies, and can become irreversible once tipping points are crossed. Climate activists are engaged in a range of activities around the world that seek to ameliorate these issues or prevent them from happening.
  
  
  The effects of climate change vary in timing and location. Up until now the Arctic has warmed faster than most other regions due to climate change feedbacks. Surface air temperatures over land have also increased at about twice the rate they do over the ocean, causing intense heat waves. These temperatures would stabilize if greenhouse gas emissions were brought under control. Ice sheets and oceans absorb the vast majority of excess heat in the atmosphere, delaying effects there but causing them to accelerate and then continue after surface temperatures stabilize. Sea level rise is a particular long term concern as a result. The effects of ocean warming also include marine heatwaves, ocean stratification, deoxygenation, and changes to ocean currents. The ocean is also acidifying as it absorbs carbon dioxide from the atmosphere.

  Health workers protest near Salmaniya Medical Complex following reports that paramedic crews and doctors were attacked in the 17 February raid at Pearl Roundabout.

  
  The Bahrain health worker trials were a series of legal cases in which forty-eight doctors, nurses, and dentists faced charges for their actions during the Bahraini uprising of 2011. In September 2011, twenty of the health workers were convicted by a military court of felonies including "stockpiling weapons" and "plotting to overthrow the government". The remaining twenty-eight were charged with misdemeanors and tried separately. The following month, the felony sentences were overturned, and it was announced that the defendants would be retried by a civilian court. Retrials began in March 2012, but were postponed until June 14. Convictions against nine of the defendants were quashed and reduced against another nine. The Court of Cassation upheld the sentences against the remaining nine on 1 October.
  
  The case drew international attention and criticism, with organizations including the United Nations, the World Medical Association, Médecins Sans Frontières, the International Council of Nurses, Amnesty International, and Human Rights Watch expressing their concern over the health workers' military trials and sentences. An independent commission organized by the King of Bahrain concluded in November 2011 that many of the detained health workers had been subject to torture and abuse while in police detention.

  Leptospira magnified 200-fold with a dark-field microscope

  
  Leptospirosis is a blood infection caused by the bacteria Leptospira that can infect humans, dogs, rodents and many other wild and domesticated animals. Signs and symptoms can range from none to mild (headaches, muscle pains, and fevers) to severe (bleeding in the lungs or meningitis). Weil's disease (/ˈvaɪlz/ VILES), the acute, severe form of leptospirosis, causes the infected individual to become jaundiced (skin and eyes become yellow), develop kidney failure, and bleed. Bleeding from the lungs associated with leptospirosis is known as severe pulmonary haemorrhage syndrome.
  
  
  More than ten genetic types of Leptospira cause disease in humans. Both wild and domestic animals can spread the disease, most commonly rodents. The bacteria are spread to humans through animal urine or feces, or water or soil contaminated with animal urine and feces, coming into contact with the eyes, mouth, nose or breaks in the skin. In developing countries, the disease occurs most commonly in pest control, farmers and low-income people who live in areas with poor sanitation. In developed countries, it occurs during heavy downpours and is a risk to pest controllers, sewage workers and those involved in outdoor activities in warm and wet areas. Diagnosis is typically by testing for antibodies against the bacteria or finding bacterial DNA in the blood. (Full article...)

  Riboflavin, also known as vitamin B₂, is a vitamin found in food and sold as a dietary supplement. It is essential to the formation of two major coenzymes, flavin mononucleotide and flavin adenine dinucleotide. These coenzymes are involved in energy metabolism, cellular respiration, and antibody production, as well as normal growth and development. The coenzymes are also required for the metabolism of niacin, vitamin B₆, and folate. Riboflavin is prescribed to treat corneal thinning, and taken orally, may reduce the incidence of migraine headaches in adults.
  
  Riboflavin deficiency is rare and is usually accompanied by deficiencies of other vitamins and nutrients. It may be prevented or treated by oral supplements or by injections. As a water-soluble vitamin, any riboflavin consumed in excess of nutritional requirements is not stored; it is either not absorbed or is absorbed and quickly excreted in urine, causing the urine to have a bright yellow tint. Natural sources of riboflavin include meat, fish and fowl, eggs, dairy products, green vegetables, mushrooms, and almonds. Some countries require its addition to grains. (Full article...)
