After living aboard the International Space Station, research into this area of physical performance may hold answers for those living with challenges from health-related concerns from prolonged inactivity.

Medicine & Health news

	You are when you eat: Limiting flies to specific eating hours protected their hearts against aging If you're looking to improve your heart health by changing your diet, when you eat may be just as important as what you eat. In a new study published today in Science, researchers at San Diego State University and the Salk Institute for Biological Studies found that by limiting the time span during which fruit flies could eat, they could prevent aging- and diet-related heart problems. The researchers also discovered that genes responsible for the body's circadian rhythm are integral to this process, but they're not yet sure how.
	Ultrasound against Alzheimer's shows promise in lab animals Queensland scientists have found that non-invasive ultrasound technology can be used to treat Alzheimer's disease and restore memory.
	Stem cells lurking in tumors can resist treatment Scientists are eager to make use of stem cells' extraordinary power to transform into nearly any kind of cell, but that ability also is cause for concern in cancer treatment. Malignant tumors contain stem cells, prompting worries among medical experts that the cells' transformative powers help cancers escape treatment.
	Immune system-in-a-dish offers hope for 'bubble boy' disease For infants with severe combined immunodeficiency (SCID), something as simple as a common cold or ear infection can be fatal. Born with an incomplete immune system, kids who have SCID—also known as "bubble boy" or "bubble baby" disease—can't fight off even the mildest of germs. They often have to live in sterile, isolated environments to avoid infections and, even then, most patients don't live past a year or two. This happens because stem cells in SCID patients' bone marrow have a genetic mutation that prevents them from developing critical immune cells, called T and Natural Killer (NK) cells.
	Optogenetics without the genetics: Nanoparticles enable stimulation of normal, non-genetically modified neurons Light can be used to activate normal, non-genetically modified neurons through the use of targeted gold nanoparticles, report scientists from the University of Chicago and the University of Illinois at Chicago. The new technique, described in the journal Neuron on March 12, represents a significant technological advance with potential advantages over current optogenetic methods, including possible use in the development of therapeutics toward diseases such as macular degeneration.
	New work schedule could cure your 'social jetlag' Many of us are walking around all the time in a fog caused by "social jetlag." That's what happens when we lose sleep because our daily schedules don't match our bodies' natural rhythms. The condition can be a particular problem for shift workers, who work into the night or on a shifting schedule. Now, researchers report in the Cell Press journal Current Biology on March 12 that sleep and workers' general wellbeing could be improved if work schedules took workers' biological clocks into account.
	Intestinal gas could be used to diagnose diseases Microbes in the human body are estimated to outnumber human cells by 10 to 1, yet research on how they affect health is still in its infancy. A perspective article published by Cell Press on March 12th in Trends in Biotechnology presents evidence that gut microbes produce gases that may contribute to gastrointestinal diseases and could be used as biomarkers for one's state of health. As means to measure these potential biomarkers, the authors suggest two novel gas-sensing systems, one of which is an electronic gas sensor in the form of a pill you can swallow. These systems may offer a reliable and economical way to understand the impact of intestinal gases on human health, paving the way for the development of new diagnostic techniques and therapies.
	Researchers find T cells target dengue virus at the skin infection site (Medical Xpress)—A team of researchers working in Singapore has found that human T cells actually target dengue viral infections in the skin, which is the normal infection site. In their paper published in the journal Science Translational Medicine, the team describes how they found that T cells in patients were able to recognize the dengue virus and also expressed a marker that caused them to move to the skin.
	New technique could lead to long-lasting localized stimulation of brain tissue without external connections Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles—a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
	Ebola outbreak of 2014 may have laid tracks for deadly measles epidemic in Africa The Ebola outbreak that has swept West Africa since 2014 may have cleared the way for a more familiar killer that could claim thousands of more lives—measles.
	Political liberals display greater happiness, study finds What does it mean to be happy? Is it how happy you say you are, or is it how happy you act? Previous research has found that political conservatives report being happier than political liberals. But UC Irvine psychologists have discovered that those on the left exhibit happier speech patterns and facial expressions.
Inflammatory factor IL-3 may play essential role in development of sepsis A new study finds that Interleukin-3 (IL-3), an inflammatory factor most associated with allergic reactions, appears to have an important role in the overwhelming, life-threatening immune reaction called sepsis. In the March 13 issue of Science, investigators from Massachusetts General Hospital (MGH) describe finding that the presence of IL-3 is essential to the development of sepsis in a mouse model of the condition and that IL-3 levels in human patients with sepsis are higher in those at greater risk of dying.
Healthy eating, exercise, and brain-training A comprehensive programme providing older people at risk of dementia with healthy eating guidance, exercise, brain training, and management of metabolic and vascular risk factors appears to slow down cognitive decline, according to the first ever randomised controlled trial of its kind, published in The Lancet.

Research shows Native American mascots and logos hurt all ethnic groups A University at Buffalo social psychologist who specializes in the study of prejudice and stigma says that American Indian nicknames and mascots are not neutral symbols, and that their continued use by schools, professional sports teams and other organizations has negative consequences for everyone, not just Native Americans.
	Repeated exposure of children to secondhand smoke is child abuse, physician argues Purposefully and repeatedly exposing children to secondhand smoke—a known human carcinogen—is child abuse, according to an opinion piece written by Adam Goldstein, MD, MPH, a professor in the Department of Family Medicine at the University of North Carolina School of Medicine. Drawing from his experience as a family physician caring for families with children who have suffered severe respiratory illness due to secondhand smoke exposure, Dr. Goldstein says it is time for society—including doctors—to do much more. Dr. Goldstein argues his point in an essay published in the Point/Counterpoint feature in the March/April 2015 issue of Annals of Family Medicine.

Creating a clean water economy It's been known since the late 1800s how to stop cholera, a waterborne infectious disease—clean water and safe sanitation are key—but that hasn't stopped it from spreading. In Haiti, more than 8,000 people have already died in a cholera epidemic that started 10 months after the massive 2010 earthquake. The disease was virtually unknown in Haiti until it was inadvertently introduced through the substandard sanitation practices of U.N. troops stationed there. The suffering caused by the disease highlighted a longstanding problem of access to clean water in the country.
Geography matters: Imaging overuse seen in certain US regions Where you receive medical care impacts many things - including whether or not you receive inappropriate medical tests, according to a new study.
Study examines association of inappropriate prostate, breast cancer imaging An association of high rates of inappropriate imaging for prostate cancer and breast cancer identified in a study of Medicare beneficiaries suggests that, at the regional level, regional culture and infrastructure could contribute to inappropriate imaging, something policymakers should want to consider as they seek to improve the quality of care and reduce health care spending, according to a study published online by JAMA Oncology.
	Germline TP53 mutations in patients with early-onset colorectal cancer In a group of patients diagnosed with colorectal cancer at 40 or younger, 1.3 percent of the patients carried germline TP53 gene mutations, although none of the patients met the clinical criteria for an inherited cancer syndrome associated with higher lifetime risks of multiple cancers, according to a study published online by JAMA Oncology.

	Scientists discover why some heart tissue turns into bone Researchers from the Gladstone Institutes have used human cells to discover how blood flow in the heart protects against the hardening of valves in cardiovascular disease. What's more, they've identified a potential way to correct this process when it goes wrong by flipping the switch on just a handful of genes. These findings may have implications for related conditions, like hardening of the arteries, which causes heart attacks and stroke.
	Spatial patterns of brain activity decode what people taste A team of researchers from the German Institute of Human Nutrition in Potsdam and the Charité University Hospital in Berlin have revealed how taste is encoded in patterns of neural activity in the human brain. Kathrin Ohla, the lead researcher on the team, said: "The ability to taste is crucial for food choice and the formation of food preferences. Impairments in taste perception or hedonic experience of taste can cause deviant eating behavior, and may lead to mal- or supernutrition. Our research aims to extend the understanding of the neuronal mechanisms of taste perception and valuation. This knowledge is essential for the development of strategies to moderate deviant eating behavior." The study was published in Current Biology.
	Evidence lacking for PT in patients with venous leg ulcers (HealthDay)—Further research is needed to understand the role of physical therapy in healing and quality of life (QOL) in patients with venous leg ulcers (VLUs), according to a systematic review published in the March issue of JAMA Dermatology.

New study finds levels of TB in Irish travellers three times that of white Irish-born population A recent study by researchers from the School of Medicine in Trinity College Dublin in conjunction with the Health Protection Surveillance Centre (HPSC) and the Pavee Point Traveller and Roma Centre has found a 3-fold higher rate of Tuberculosis (TB) in Irish Travellers than in the white Irish born population. The findings were recently published in the international journal Epidemiology & Infection (Cambridge University Press).
Low breast density in mammography worsens breast cancer prognosis Very low mammographic breast density worsens the prognosis of breast cancer, according to a recent study from the University of Eastern Finland. Disease free survivals as well as overall life expectancies were significantly shorter in women with very low-density breasts in comparison to women with high density breast tissue. The lower the breast tissue density, the less fibroglandular tissue there is compared to fat tissue.
'Mind reading' thanks to metaphors Observe whether two people use metaphors in conversation with each other if you want to guess how close they are as friends. Or sharpen your ability to tune into other people's emotional or mental states by observing the metaphors they use. Why is this? Because metaphors can in fact help one to 'mind read,' report Andrea Bowes and Albert Katz of the University of Ontario in Canada in Springer's journal Memory & Cognition.
Study bolsters 'turbocharged' protein as a promising tool in hemophilia gene therapy Using gene therapy to produce a mutant human protein with unusually high blood-clotting power, scientists have successfully treated dogs with the bleeding disorder hemophilia, without triggering an unwanted immune response. In addition, the "turbocharged" clotting factor protein eliminated pre-existing antibodies that often weaken conventional treatments for people with hemophilia.
Reaching '80 percent by 2018' would prevent more than 20,000 colorectal cancer deaths per year Increasing colorectal cancer screening rates to 80% by 2018 would prevent an additional 21,000 colorectal cancer deaths per year by 2030, according to a new study. The study is the first to estimate the public health benefits of increasing screening rates to "80% by 2018," a recent initiative from the National Colorectal Cancer Roundtable (NCCRT), a national coalition of public, private, and voluntary organizations, to aim for screening rates of 80% in the United States by 2018. The study is co-authored by American Cancer Society epidemiologist Ahmedin Jemal and appears in Cancer, a peer-reviewed journal of the American Cancer Society.

	FDA wants more info on scopes linked to "superbug" outbreaks (Update) Federal health officials issued multiple announcements Thursday aimed at addressing growing safety concerns about medical scopes that have been linked to several recent "superbug" outbreaks.
Raising minimum age to buy cigarettes to at least 21 would reduce smoking and save lives Increasing the minimum age of legal access (MLA) to tobacco products will prevent or delay initiation of tobacco use by adolescents and young adults, particularly those ages 15 to 17, and improve the health of Americans across the lifespan, says a new report from the Institute of Medicine. The committee that conducted the study estimated the likely reduction in tobacco-use initiation that would be achieved by raising the MLA for tobacco products to either 19 years old, 21 years old, or 25 years, and used two tobacco-use simulation models to quantify the accompanying public health outcomes.
Statin guidelines miss middle-age patients and over-target seniors The newest guidelines for the use of cholesterol-lowering statins in people at risk of heart disease may be too generic, excluding middle-aged adults who could benefit from the drugs, and over-prescribing in older adults, according to a new study from the Duke Clinical Research Institute.
Age-related discrimination can add to healthcare woes Being discriminated against by the healthcare profession or system can cause much more than just mere distress to older people. Such experiences can literally be bad for their health. A national survey shows that one in every three older Americans who are on the receiving end of age-related discrimination in the healthcare setting will likely develop new or worsened functional ailments in due course. This follows a study1 led by Stephanie Rogers, a fellow in geriatrics at UC San Francisco in the United States, and published in the Journal of General Internal Medicine2, published by Springer.
Researchers develop database on healthy immune system An extensive database identifying immune traits, such as how immune cell function is regulated at the genetic level in healthy people, is reported by researchers from the National Institutes of Health (NIH) and their collaborators in the journal Cell. While many genetic risk factors have been linked to various diseases, including autoimmune disorders, how a genetic change causes susceptibility to a disease is not always clear. By studying healthy people, researchers from the National Institute of Allergy and Infectious Diseases (NIAID) Vaccine Research Center, part of the NIH, and colleagues from King's College London have created a reference resource for other scientists.
	Largest review of clinical trials to assess risk of patients using Champix Findings from the largest review of clinical trials to date to determine whether patients prescribed the smoking cessation drug Varenicline (brand name Champix in the UK) are at an increased risk of neuropsychiatric events are published online in the British Medical Journal (BMJ) today. The study was carried out by researchers at the University of Bristol.
	Study details microRNA's role as a double agent during Hep C infection In the battle between a cell and a virus, either side may resort to subterfuge. Molecular messages, which control the cellular machinery both sides need, are vulnerable to interception or forgery. New research at Rockefeller University has revealed the unique twist on just such a strategy deployed by the liver-infecting Hepatitis C virus - one that may help explain the progression of liver disease and that the researchers suspect may be found more widely in the world of disease-causing viruses.
	Gene leads to malformation of the urinary tract An interdisciplinary team of researchers under the direction of the University of Bonn Hospital have discovered a gene which is associated with a rare congenital anomaly of the urinary tract called classic bladder exstrophy. It increases the likelihood that the urinary tract will not form properly during embryonic development. The finding is an important step for understanding the development of urinary tract malformations in general and for developing prophylactic measures. The results are published in the current online edition of the journal PloS Genetics.
	Predicting your risk of infection Research publishing this week in PLOS Computational Biology analyses the livestock trade in Italy and sexual encounters in a Brazilian prostitution service to find a correlation between loyalty and infection risk.
High cholesterol, triglycerides can keep vitamin E from reaching body tissues In the continuing debate over how much vitamin E is enough, a new study has found that high levels of blood lipids such as cholesterol and triglycerides can keep this essential micronutrient tied up in the blood stream, and prevent vitamin E from reaching the tissues that need it.
	Hospital ratings on social media appear to reflect quality of care, study says Social media has become an important way for institutions to communicate - both sending messages and receiving feedback - with clients and with the general public. Hospitals and other health care organizations use social media for a variety of purposes, but there has been little investigation of whether hospitals ratings that patients and other consumers submit via social media accurately reflect patient satisfaction or the quality of care delivered. A new study published online in the Journal of General Internal Medicine finds a correlation between how hospitals are rated on Facebook's five-star system and how well they performed on a widely-used measure of quality care.

	E-cigarette advertising makes one crave ... tobacco? Television advertisements for e-cigarettes may be enticing current and even former tobacco smokers to reach for another cigarette.
	Cancer drug promotes regeneration of damaged neurons Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves. An international team of researchers led by DZNE scientists in Bonn now reports in Science that help might be on the way from an unexpected quarter: in animal studies, the cancer drug epothilone reduced the formation of scar tissue in injuries to the spinal cord and stimulated growth in damaged nerve cells. Both promoted neuronal regeneration and improved the animals' motor skills.
German biologist who denies measles virus exists ordered to pay A German biologist who promised to pay 100,000 euros to anyone who could prove that the measles was indeed a virus was ordered by a court on Thursday to hand over the money.
Depression in dads as well as moms causes anxiety and bad behavior in toddlers A father's depression during the first years of parenting - as well as a mother's - can put their toddler at risk of developing troubling behaviors such as hitting, lying, anxiety and sadness during a critical time of development, according to a new Northwestern Medicine study.

The article will appear in print in the April issue of the Journal.
Health law hasn't cut insurers' rate of overhead spending Despite claims by the Obama administration that the Affordable Care Act will reduce health insurance companies' spending on overhead, thereby channeling a greater share of consumers' premium dollars into actual patient care, insurers' financial filings show the law had no impact on the percentage of insurer expenditures on such things as administration, marketing and profits.
'Low risk' bird flu outbreak at Dutch farm: official Dutch authorities have identified an outbreak of avian flu in chickens at a farm in the centre of the country that is likely a "low risk" strain, officials said Thursday.
The ACA may reduce ER visits (slightly) but doesn't affect hospitalizations Two patient groups created by the Affordable Care Act (ACA) - Medicare patients enrolled in federally designated patient-centered medical homes and people under age 26 who are allowed to remain on their parents' health insurance - had slightly fewer emergency department visits than they had before health care reform. However, there was no change in the rate of the most expensive types of emergency visits: those that lead to hospitalization.
	Can breastfeeding women have menopause-like symptoms? After giving birth, a woman's estrogen levels drop to lower than usual levels, and while they return to the normal range relatively quickly among women who are not breastfeeding, this hypoestrogenic state may continue in lactating women and cause menopause-like symptoms. The results of a new study comparing vaginal dryness, hot flashes, and mood changes in women who are or are not breastfeeding 3 and 6 weeks after giving birth are reported in Breastfeeding Medicine, the official journal of the Academy of Breastfeeding Medicine.
