ACPM concludes insufficient evidence to recommend routine prostate cancer screening

The American College of Preventive Medicine (ACPM) has found there is insufficient evidence to recommend for or against routine population prostate screening with digital rectal examination (DRE) or measurement of the serum tumor marker, prostatespecific antigen (PSA). ACPM advises that clinicians caring for men, especially African-American men and those with a family history, should provide information about the potential benefits and harms of screening and limits of current evidence to allow for them to make an informed decision about screening. more


AHRQ releases consumer financial incentives guide for employers and other health care purchasers

ASGE encourages patients to see a physician if they experience symptoms suggestive of GERD

A recent study from the Agency for Healthcare Research and Quality shows that hospitalizations for disorders caused by gastroesophageal reflux disease or GERD rose 103 percent between 1998 and 2005. Also, hospitalizations for patients who had milder forms of GERD (in addition to the condition for which they were admitted), rose by 216 percent during the same time period. The numbers underscore the importance of seeing a physician if symptoms suggestive of GERD are present. more

Abuse history affects pain regulation in women with irritable bowel syndrome  

UCLA and University of North Carolina researchers have found that women with irritable bowel syndrome (IBS) who have experienced sexual and/or physical abuse may have a heightened brain response to pain that makes them more sensitive to abdominal discomfort. IBS is a condition that affects 10 to 15 percent of the population and causes gastrointestinal discomfort along with diarrhea, constipation or both. more

Achieving a US health care system 'second to none'  

All candidates running for office in 2008 should commit to an agenda to create a health care system for the United States that is second to none the American College of Physicians (ACP) said today in its annual report on The State of the Nation’s Health Care. In its report, ACP offers a five-point Candidate’s Pledge designed to gain candidate commitments to support a series of recommendations. more

Acid-seeking “warheads” promise safer, more effective cancer weapons

Researchers in California report development of an anti-cancer “warhead” that targets the acidic signature of tumor cells in much the same way that heat-seeking missiles seek and destroy military targets that emit heat. These acid-seeking substances are not toxic to healthy cells, and represent a new class of potentially safer, more effective anti-cancer drugs, they say. more

Actual use of asthma medications contradicts guidelines

A study has found only 16% of the 352,082 Australians who filled a prescription for asthma preventer medications for the first time during the period July 2004 to June 2005, went on to use them regularly. more


Acupuncture shows promise in improving rates of pregnancy following IVF

A review of seven clinical trials of acupuncture given with embryo transfer in women undergoing in vitro fertilization (IVF) suggests that acupuncture may improve rates of pregnancy. An estimated 10 to 15 percent of couples experience reproductive difficulty and seek specialist fertility treatments, such as IVF. IVF, which involves retrieving a woman's egg, fertilizing it in the laboratory, and then transferring the embryo back into the woman's womb is an expensive, lengthy, and stressful process. more  

Acute pesticide poisoning: A proposed classification tool

Aggressively lowering cholesterol and blood pressure may reverse atherosclerosis in adults with diabetes

Aggressively lowering cholesterol and blood pressure levels below current targets in adults with type 2 diabetes may help to prevent — and possibly reverse — hardening of the arteries, according to new research supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. Hardening of the arteries, also known as atherosclerosis, is the number one cause of heart disease and can lead to heart attack, stroke, and death. more  

ALS Aggregates are composed of only one protein

Researchers have provided a big new clue to help combat amyotrophic lateral sclerosis (ALS), deciphering that the dense protein aggregates that contribute to the nerve decay of ALS are composed of just one protein: superoxide dismutase (SOD1). more

Alcohol and sleep

The average adult sleeps 7.5 to 8 hours every night. Although the function of sleep is unknown, abundant evidence demonstrates that lack of sleep can have serious consequences, including increased risk of depressive disorders, impaired breathing, and heart disease. In addition, excessive daytime sleepiness resulting from sleep disturbance is associated with memory deficits, impaired social and occupational function, and car crashes (1,2). Alcohol consumption can induce sleep disorders by disrupting the sequence and duration of sleep states and by altering total sleep time as well as the time required to fall asleep (i.e., sleep latency). more

Alcohol can benefit the hearts of new drinkers

A Medical University of South Carolina’s (MUSC) Department of Family Medicine study concluded that people who began moderately consuming alcohol in middle-age experience a quick benefit of lower rates of cardiovascular disease morbidity with no change in mortality after four years. more

Anti-cancer drug damages brain vessels

The cancer drug Avastin (bevacizumab) is used to treat advanced bowel cancer in combination with chemotherapy. This drug targets a protein called VEGF (vascular endothelial growth factor) that stimulates blood vessel growth. Avastin inhibits the growth of tumors by cutting off their blood supply, which deprives them of oxygen and other nutrients. more

Anticipating a laugh reduces stress hormones

In 2006 researchers investigating the interaction between the brain, behavior, and the immune system found that simply anticipating a mirthful laughter experience boosted health-protecting hormones. Now, two years later, the same researchers have found that the anticipation of a positive humorous laughter experience also reduces potentially detrimental stress hormones. According to Dr. Lee Berk, the study team’s lead researcher of Loma Linda University, Loma Linda, CA, “Our findings lead us to believe that by seeking out positive experiences that make us laugh we can do a lot with our physiology to stay well.” more

Antioxidants hope or hype? Mayo researchers look at effects of antioxidant supplements on cancer  

While some trials have suggested that antioxidants have beneficial effects, results from other trials have been negative. It has been unclear which antioxidant compounts are more beneficial (or more harmful), and how individual antioxidants affect target organs and specific patient populations. more

Breast cancer deaths did decrease, but new research has unveiled a discrepancy: African-American women as a group do not benefit as much as white women. more


Best health advice? Be happy with your fat self. Desire to lose weight, not weight itself linked to unhealthy days

In a study to examine the impact of desired body weight on the number of unhealthy days subjects report over one month, researchers at Columbia University Mailman School of Public Health found that the desire to weigh less was a more accurate predictor of physically and mentally unhealthy days, than body mass index (BMI). In addition, the desire to lose weight was more predictive of unhealthy days among Whites than among African-Americans or Hispanics, and among women than among men. The paper, I Think Therefore I Am: Perceived Ideal Weight as a Determinant of Health, will be published in the March issue of the American Journal of Public Health. more  

Better and faster: Distinguishing non-TB pulmonary disease from TB

Biochemical signals associated with atherosclerosis may damage other organs  

Many scientists view atherosclerosis, or hardening of the arteries, as a localized disease characterized by the build up of fatty plaques in the arteries, which can eventually cause heart attacks and strokes. Now, in a finding that challenges conventional knowledge, researchers in New York and North Carolina report that plaques formed in arteries are associated with certain harmful chemical reactions that can contribute to damage in the lungs, liver, and other organs. more


Bio-identicals: Sorting myths from facts

"BHRT" is a marketing term not recognized by FDA. Sellers of bio-identicals often claim that these "all-natural" pills, creams, lotions, and gels are without the risks of synthetic FDA-approved drugs for menopausal hormone therapy (MHT). FDA-approved MHT drug products provide effective relief of the symptoms of menopause such as hot flashes and vaginal dryness. They also can prevent thinning of bones. more  

Biomarkers linked to DCIS outcomes

Ductal carcinoma in situ (DCIS), where abnormal cells are found in the lining of a breast duct, is usually treated with surgical lumpectomy, followed by radiation, chemotherapy, a combination of the two, or surveillance. Most women undergoing these treatments will not experience a recurrence, but in 15 to 30 percent of women, a new tumor will develop within 10 years, and about half of these will be invasive breast cancers. more

Biopsy techniques have made PSA test less predictive

Prostate specific antigen (PSA) levels typically have correlated with prostate biopsy results in the detection of prostate cancer, but that correlation no longer exists for men with a normal prostate exam, according to a new study published in the April 15, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study suggests that improved biopsy techniques make PSA less useful in prostate cancer screening. more

Black British women younger at breast cancer diagnosis

In the first published study of patterns of breast cancer in British black women, available online January 8 in the British Journal of Cancer, researchers found that black women were diagnosed with invasive breast cancer at a significantly younger median age than white women and had a higher frequency of higher grade tumors, estrogen receptor (ER)-negative, and basal-like (triple negative) tumors, similar to African American women. more

Brain-imaging study may explain why some continue to eat, despite full stomachs  

Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have found new clues to why some people overeat and gain weight while others don't. Examining how the human brain responds to "satiety" messages delivered when the stomach is in various stages of fullness, the scientists have identified brain circuits that motivate the desire to overeat. Treatments that target these circuits may prove useful in controlling chronic overeating, according to the authors. The study is published online and will appear in the February 15, 2008 issue of NeuroImage. more

Brain network linked to contemplation in adults is less complex in children

A brain network linked to introspective tasks -- such as forming the self-image or understanding the motivations of others -- is less intricate and well-connected in children, scientists at Washington University School of Medicine in St. Louis have learned.

Catheter repair of mitral valve improves heart size, symptoms

A catheter-mounted device that acts like a clothespin to clip together the flaps of a leaky heart valve is not only reducing the abnormal backflow of blood from the left ventricle to the left atrium, it is helping to shrink the enlarged, overworked heart and relieving symptoms of fluid overload—all without open-chest surgery. These are the one-year findings in a small group of patients enrolled in the Endovascular Valve Edge-to-Edge Repair Study (EVEREST), which is evaluating the use of the MitraClip for the treatment of mitral regurgitation (MR). more

Caution advised when using hormone therapy for prostate cancer  

In men with localized but aggressive prostate cancer, the combination of testosterone-lowering therapy and radiation improves survival substantially more than radiation therapy alone. But testosterone-lowering therapy isn’t so hot for the heart, reports the April issue of the Harvard Heart Letter. Low testosterone can increase harmful LDL cholesterol, blood sugar, blood pressure, and weight. It can also make arteries stiffer, promote formation of artery-clogging plaque, and allow blood clots to form more readily. more

Cervical vaccine hurts, but it's probably worth the sting 

The vaccine against cervical cancer, Gardasil, has been the subject of several complaints from women who have received it. According to stories appearing in the Associated Press, complaints such as: "It burns!" and "the burning is worse than with other kinds of vaccines I've had." There are also complaints about pain and discomfort in the arm for a day or two after getting the shot. There are also reports of women fainting after receiving Gardasil, but there's no clear information about whether this is a form of hysteria, whether the girls are fainting from nerves, fear, or pain. more

Countering tobacco use among young adults: new approaches needed  

For the tobacco industry, a 22-year-old who isn't a smoker represents a challenge but also an opportunity. The reason: While most - but by no means all - smokers start as teenagers, only about one-third are fully addicted smokers by age 18. Young adulthood, typically defined as ages 18 to 25, is when many transition from light smokers to heavy smokers - or quit. If smoking hasn't taken root by age 25, studies show, chances are good it's not going to. more

Craniosynostosis minimally invasive surgery holds more promise than old procedure  

Craniosynostosis, the premature fusion of the skull, is estimated to affect one out of every 2,000 babies. For the past several years, physicians have used two procedures to correct the problems. One procedure was to make an incision from ear to ear, strip back the scalp of the infant and reshape the skull by breaking the bones that had fused. The other procedure required a small incision near the point of the fused skull plates. Now, the first long-term study by a researcher at the University of Missouri School of Medicine found that the minimally invasive technique is just as effective and results in a quicker recovery time than the old technique. more

Diuretics most effective blood pressure medication for people with metabolic syndrome: Evidence strongly supports diuretics as initial therapy, especially in black patients

New research shows that in people with high blood pressure as part of metabolic syndrome, a cluster of conditions that increases the risk for heart disease, diuretics offer greater protection against cardiovascular disease, including heart failure, and are at least as effective for lowering blood pressure as newer, more expensive medications. The findings run counter to current medical practices that favor ACE-inhibitors, alpha-blockers, and calcium channel blockers for treatment of high blood pressure in those with metabolic syndrome. In addition, the results provide important new evidence supporting the use of diuretics for initial blood pressure-lowering therapy in black patients with metabolic syndrome. more

Drug-eluting stents -- More good than harm for heart patients?

The incidence of type 2 diabetes in Western society is on the rise, due largely to an increasing prevalence of obesity. Dysfunction of skeletal muscle mitochondria, the powerhouses of a cell, is associated with type 2 diabetes; however, whether this association is causal or consequential has not been understood. A new study by Jennifer Rieusset and her colleagues at INSERM U870, France, has shed light on this question and has provided evidence that alterations in mitochondrial function are the result, and not the cause, of insulin resistance (which usually precedes full-blown clinical type 2 diabetes) in mice. more

Finding the roots of hair loss

A healthy individual loses around a hundred hairs a day. Nothing to worry about as long as they are constantly replaced and the losses occur evenly around the whole scalp. But when hair loss goes well beyond this level it can become quite a problem for those affected – not only superficially in terms of looks but also psychologically. A breakthrough on the hair front has now been made by an international research team headed by scientists at the University of Bonn. After six years of research they have succeeded in identifying a gene that is responsible for a rare hereditary form of hair loss known as Hypotrichosis simplex. more

Geneticist first to connect a gene central to neuron formation to autism

Eli Hatchwell, M.D., Ph.D., Associate Professor of Pathology at Stony Brook University Medical Center, and colleagues have found that a disruption of the Contactin 4 gene on chromosome 3 may be linked to autism spectrum disorder (ASD). What causes ASD, a developmental disorder of the central nervous system, is largely unknown. Dr. Hatchwell’s finding suggests that mutations affecting Contactin 4 may be relevant to ASD pathogenesis, and thus a potential biomarker for some individuals with the disorder. Details of the study are reported in the early online edition of the Journal of Medical Genetics. more

Half of the people suffering from head injuries that go to court fake their ailments to receive financial help

How can it be proved that a patient is lying when they say that they have a cognitive problem, such as memory or concentration problems or anxiety? There are many people who exaggerate their injuries and even feign them in order to receive more money from insurance companies or obtain a sick leave, according to a pioneering research in Spain. This research was carried out in the Department of Personality, Assessment and Psychological Treatment of the University of Granada by Doctor Raquel Vilar López. The conclusions of her study, which focused on patients who suffered from head injuries, speak for themselves: nearly half of the people who go to court feign psycho-cognitive disorders with the objective of profiting from this in some way. They are not hypochondriacs or overanxious or obsessive patients, they just lie in order to receive some sort of compensation, as for example money. They are the so called ‘simulators’. more

Heart and stroke death rates steadily decline; risks still too high  

In an appropriate prelude to American Heart Month, which is just ahead in February, new mortality data from the Centers for Disease Control and Prevention (CDC) shows that, since 1999, coronary heart disease and stroke age-adjusted death rates are down by 25.8 percent and 24.4 percent, respectively. This means that the American Heart Association’s 2010 strategic goal for reducing deaths from coronary heart disease has been achieved, and for stroke nearly achieved – ahead of time. However, potential problems loom for the future, as all of the major risk factors for these leading causes of death are still too high and several are actually on the rise. If this trend continues, death rates could begin to rise again in years ahead. more

How antioxidant therapy may play a role in the treatment of type 2 diabetes

The incidence of type 2 diabetes in Western society is on the rise, due largely to an increasing prevalence of obesity. Dysfunction of skeletal muscle mitochondria, the powerhouses of a cell, is associated with type 2 diabetes; however, whether this association is causal or consequential has not been understood. A new study by Jennifer Rieusset and her colleagues at INSERM U870, France, has shed light on this question and has provided evidence that alterations in mitochondrial function are the result, and not the cause, of insulin resistance (which usually precedes full-blown clinical type 2 diabetes) in mice. more


How much protein do you need?

The idea of eating more protein has gained popularity in the past few years. Some people may think the way to build body muscle is to eat high-protein diets and use protein powders, supplements and shakes. But there’s no solid scientific evidence that most Americans need more protein. Most of us already get all we need. Some of us may even be eating much more than we need. more

Infectious disease facts: The difference between latent TB infection and active TB disease

Tuberculosis (TB) is a disease caused by a germ called Mycobacterium tuberculosis that is spread from person to person through the air. TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine. When a person with infectious TB coughs or sneezes, droplet nuclei containing M. tuberculosis are expelled into the air. If another person inhales air containing these droplet nuclei, he or she may become infected. However, not everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist: latent TB infection and active TB disease. more

A major step toward a more targeted treatment for auto-immune diseases?

More and more people in Western society are suffering from auto-immune diseases. Discovering the cause of these chronic inflammations is a first important step in the search for targeted medicines. VIB researchers connected to Ghent University and the Katholieke Universiteit Leuven joined forces and have elucidated the function of MALT1, a key player in controlling inflammatory reactions. They are the first to show that MALT1 is able to cleave the A20 protein, which inhibits inflammation. Scientists hope that by counteracting MALT1 they will be able to restore the body’s natural inhibition of inflammation and thus provide an alternative for treatments that tax the immune system. This would represent a profound improvement over current medicines. Their research will be published in the authoritative journal Nature Immunology. more

Memories, stolen by stress hormones, at least in rodents

Diabetes is known to impair the cognitive health of people, but now scientists have identified one potential mechanism underlying these learning and memory problems. A new National Institutes of Health (NIH) study in diabetic rodents finds that increased levels of a stress hormone produced by the adrenal gland disrupt the healthy functioning of the hippocampus, the region of the brain responsible for learning and short-term memory. Moreover, when levels of the adrenal glucocorticoid hormone corticosterone (also known as cortisol in humans) are returned to normal, the hippocampus recovers its ability to build new cells and regains the "plasticity" needed to compensate for injury and disease and adjust to change. more

New study of targeted therapies for breast cancer -- model for global clinical trials

Two targeted medications designed to treat an aggressive form of breast cancer are being tested in a new study involving 8,000 participants in 50 countries across six continents -- a clinical trial that investigators hope will provide a new model for global cancer research. This trial, dubbed ALTTO (Adjuvant Lapatinib and/or Trastuzumab Treatment Optimization study), will be one of the first global initiatives in which two large, academic breast cancer research networks covering different parts of the world have jointly developed a study in which all care and data collection are standardized, regardless of where patients are treated. more

A new way to boost red blood cell numbers

A common treatment for anemia — a deficiency in red blood cells (rbcs) caused by their insufficient production, excessive destruction, or excessive loss — is administration of recombinant erythropoietin (Epo), a hormone that stimulates the production of rbc precursors by the bone marrow. Unfortunately, many patients with anemia do not respond to treatment with Epo. However, a new study in mice, by Anne Angelillo-Scherrer and her colleagues at the University Hospital Center and University of Lausanne, Switzerland, has indicated that the protein Gas6 might augment or replace Epo in the treatment of patients who are hyporesponsive or resistant to Epo, respectively. more

Nonprotruding colorectal growths may harbor cancer

Most colorectal cancers are thought to arise from polypoid adenomas - growths that protrude from the mucous membrane in the colon or rectum. A study from the Veterans Affairs (VA) Health Care System in Palo Alto, CA, published in the March 5 Journal of the American Medical Association adds to a growing body of evidence that nonpolypoid colorectal neoplasms (NP-CRNs) - abnormalities that can appear either flat or depressed relative to the surrounding membrane - can also contain precancerous or cancerous cells. Previous studies established the existence of NP-CRNs in Japan, but their prevalence and importance in other parts of the world has remained unclear. more  

Normal weight obesity: An emerging risk factor for heart and metabolic problems  

More than half of American adults considered to have normal body weight in America have high body fat percentages -- greater than 20 percent for men and 30 percent for women -- as well as heart and metabolic disturbances, new Mayo Clinic research shows. The finding conflicts with the widely held belief that maintaining a normal weight automatically guards against disorders such as high levels of circulating blood fats and a tendency to develop metabolic syndrome, which often leads to type 2 diabetes. more

Oral contraceptives and cancer risk: Questions and answers

Oral contraceptives (OCs) first became available to American women in the early 1960s. The convenience, effectiveness, and reversibility of action of birth control pills (popularly known as “the pill”) have made them the most popular form of birth control in the United States. However, concerns have been raised about the role that the hormones in OCs might play in a number of cancers, and how hormone-based OCs contribute to their development. Sufficient time has elapsed since the introduction of OCs to allow investigators to study large numbers of women who took birth control pills for many years. more

Oral contraceptives reduce long-term risk of ovarian cancer

Since they were first licensed nearly 50 years ago, birth control pills containing estrogen have prevented some 200,000 cases of ovarian cancer world-wide, estimate the authors of a study published January 26 in The Lancet. Further, in the absence of having taken oral contraceptives, half of these women would have died of the disease. more

Oral osteoporosis meds appear to reduce the risk of jaw degradation

Panel finds hydroxyurea treatment is underutilized for sickle cell disease

An independent panel convened this week by the NIH concluded that the use of hydroxyurea for sickle cell patients should be increased in adolescents and adults. Hydroxyurea was approved by the U.S. Food and Drug Administration for use in adults with sickle cell anemia in 1998, but provider and patient concerns have hindered its use, depriving many patients of its proven benefits. Research has shown that sickle cell patients on this drug experience fewer pain crises and hospital admissions, and the panel advocated increased utilization of this drug with appropriate monitoring. Additionally, the panel concluded that the risks of serious side effects of hydroxyurea appear to be lower than previously expected. more

Rise and walk again

Spinal cord injuries sever the connection between the brain and body. Researchers have long thought that, to restore movement, the long nerve fibers that run from the brain to the lower spinal cord had to be regrown. A new study in mice showed that nerves within the spinal cord can rearrange and restore those connections. The finding could lead to new therapies for the estimated 250,000 Americans living with spinal cord injuries. more  

The risk of osteoarthritis and index to ring finger length ratio 

Index to ring finger length ratio (2D:4D) is a trait known for its sexual differences. Men typically have shorter second than fourth digits; in women, these fingers tend to be about equal in length. Smaller 2D:4D ratios have intriguing hormonal connections, including higher prenatal testosterone levels, lower estrogen concentrations, and higher sperm counts. Reduction in this ratio has also been linked to athletic and sexual prowess. Whether this trait affects the risk of osteoarthritis (OA), a progressive joint disease associated with both physical activity and estrogen deficiency, has not been examined. Until recently. more

Study suggests antibiotic may prevent dreaded brain fever

Two researchers from National Brain Research Center (NBRC) suggest that a common antibiotic called minocycline may prevent children from death due to Japanese encephalitis (JE), or commonly known as brain fever. Japanese Encephalitis virus is the causative agent for JE. Although there is no consolidated official figure for JE cases in India, a rough estimate would indicate a few thousands fatalities every year. The team found that minocycline, an USFDA approved drug, often used to treat acne, limits the death by reducing the microglial activation, neuronal death as well as viral replication. Microglia are cells that act as the "cleanup crew" for the Central Nervous System (CNS). They destroy damaged cells by releasing toxins and engulfing them. Should they become activated and release their toxins in the CNS, the toxins will kill the healthy neurons critical for normal function of brain. more  

Study sheds important new light on inherited disorder causing iron overload

Research in today’s New England Journal of Medicine shows hereditary hemochromatosis is much more common than previously thought and will spur more study to determine who is most likely to develop complications from the debilitating and potentially fatal disease, write two faculty members at the Saint Louis University School of Medicine.

Sunitinib linked to heart failure and hypertension

Patients taking sunitinib (Sutent) should be monitored for cardiovascular side effects such as hypertension and signs of heart failure, especially those patients with a history of coronary artery disease or cardiac risk factors, a team of oncologists and cardiologists said last month in The Lancet. The recommendation is based on evidence of cardiac side effects among some patients taking sunitinib to treat gastrointestinal stromal tumors (GIST). Sunitinib is approved to treat advanced renal cell carcinoma and metastatic GIST after resistance to imatinib (Gleevec) develops. more

Supplement use and cancer

Many current and former cancer patients take vitamin and mineral supplements. They may believe these supplements can help reduce treatment side effects. They may think extra vitamins will keep cancer from coming back or help them live longer. But research in these areas hasn’t yet found whether many of these beliefs are true. And some doctors worry that supplements can interact with cancer treatments or have other unintended consequences. more

TAG - YOU DIDN'T WASH YOUR HANDS!!!

Two scientists from Duke University have found a way to tag healthcare workers to make sure they're washing their hands. While it's a bit unsettling to think of nurses tagged like deer, it's comforting to know that the devices could cut down on the approximately 100,000 deaths from hospital-acquired infections each year. more  

Taking more than 1 anti-inflammatory drug may lead to complications

Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to treat arthritis, which affects one-third of all adults. These drugs are available in both prescription and over-the-counter (OTC) forms and are one of the most commonly prescribed medications in the world. Because of their widespread availability, patients may take both forms at the same time, either because of inadequate pain relief or because they are unaware that they are taking two drugs in the same therapeutic class. At the same time, health care providers may also be unaware that patients are taking more than one NSAID. more

Targeting astrocytes slows disease progression in ALS

In what the researchers say could be promising news in the quest to find a therapy to slow the progression of amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease, scientists at the University of California, San Diego (UCSD) School of Medicine have shown that targeting neuronal support cells called astrocytes sharply slows disease progression in mice. more

Treatment with an antipsychotic drug found to cause changes in metabolism earlier than expected

Schizophrenia is a complex type of psychotic mental illness characterized by thoughts that are uncoupled from reality. Huge gains in the effective treatment of individuals with the disease began in the 1950s with the development of the first generation of antipsychotic drugs. The medications allowed physicians to treat the “positive” effects of the illness (delusions and hallucinations) and, to a lesser extent, the “negative” symptoms (apathy). more
