Medicine & Health news

	Why cancer cells grow despite a lack of oxygen Healthy cells reduce their growth when there is a lack of oxygen (hypoxia). This makes it even more surprising that hypoxia is a characteristic feature of malignant tumours. In two publications in the current edition of the Nature Communications journal, researchers from Goethe University and Justus-Liebig-University of Giessen report on how cancer cells succeed at circumventing the genetic program of growth inhibition.
Providing simple neural signals to brain implants could stand in for body's own feedback system In new research that brings natural movement by artificial limbs closer to reality, UC San Francisco scientists have shown that monkeys can learn simple brain-stimulation patterns that represent their hand and arm position, and can then make use of this information to precisely execute reaching maneuvers.
	Virtual motion, real consequences Ludwig Maximilian University of Munich researchers have shown that virtual optical stimuli can lead to aftereffects that significantly alter our perception of self-motion. This finding has implications for safe use of emerging technologies such as virtual-reality headsets.
	Scientists link gene to tamoxifen-resistant breast cancers After mining the genetic records of thousands of breast cancer patients, researchers from the Johns Hopkins Kimmel Cancer Center have identified a gene whose presence may explain why some breast cancers are resistant to tamoxifen, a widely used hormone treatment generally used after surgery, radiation and other chemotherapy.
	Researchers find brain network link between development, aging and brain disease (Medical Xpress)—A team of bio-researchers with members from across Europe has found evidence that suggests that grey matter development early in life tends to be the first to regress later in life—related findings also suggest a possible link between brain diseases such as Alzheimer's and schizophrenia. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they came to these conclusions after studying a large number of brain scans.
	Missing gene linked to autism Researchers at the University of Leeds have shed light on a gene mutation linked to autistic traits.

	Vegetable oil ingredient key to destroying gastric disease bacteria The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. To combat the infection, researchers at University of California, San Diego School of Medicine and Jacobs School of Engineering developed LipoLLA, a therapeutic nanoparticle that contains linolenic acid, a component in vegetable oils. In mice, LipoLLA was safe and more effective against H. pylori infection than standard antibiotic treatments.
	A link between DNA transcription and disease-causing expansions Researchers in human genetics have known that long nucleotide repeats in DNA lead to instability of the genome and ultimately to human hereditary diseases such Freidreich's ataxia and Huntington's disease.
	Mere expectation of treatment can improve brain activity in Parkinson's patients Learning-related brain activity in Parkinson's patients improves as much in response to a placebo treatment as to real medication, according to a new study by researchers at the University of Colorado Boulder and Columbia University.
	Novel type 1 diabetes treatment shown to work on human beta cells transplanted into mice A chemical produced in the pancreas that prevented and even reversed Type 1 diabetes in mice had the same effect on human beta cells transplanted into mice, new research has found.

Fortunately, you can have your pie and eat it, too.
Researcher examines effect of marital strain on caregivers Caring for a chronically ill family member can impact the caregiver's physical, biological and mental health, according to assistant professor SunWoo Kang of the South Dakota State University counseling and human development department. She analyzed the selfreported health of married, adult caregivers from the National Survey of Midlife in the United States.
	Brain abnormality found in group of SIDS cases More than 40 percent of infants in a group who died of sudden infant death syndrome (SIDS) were found to have an abnormality in a key part of the brain, researchers report. The abnormality affects the hippocampus, a brain area that influences such functions as breathing, heart rate, and body temperature, via its neurological connections to the brainstem. According to the researchers, supported by the National Institutes of Health, the abnormality was present more often in infants who died of SIDS than in infants whose deaths could be attributed to known causes.
	Study reveals new findings about cause of lesions around jaw bone Osteonecrosis of the jaw is a debilitating and painful condition in which oral lesions develop in individuals taking drugs such as bisphosphonate or denosumab, which are commonly used in treatments for osteoporosis and for cancers that have spread to the bones. Although formally identified in 2003, the fundamental causes for osteonecrosis of the jaw (ONJ) development and its treatment remain unclear. New research provides a better understanding of how ONJ progresses and its cellular and structural activators, which could guide the development of therapeutic and preventive measures.
	A new nanomachine shows potential for light-selective gene therapy Gene therapy has great potential to treat intractable diseases such as cancer, arterial sclerosis, and Parkinson's disease. Successful gene therapy requires a gene vector that can deliver the therapeutic gene selectively to the target site. However, the concern is that conventional gene vectors can cause non-selective transfection to normal organs, whereby genetic material infiltrates healthy cells and leads to unfavorable side effects.
	Oral health improves via education Better integration with primary health care, community outreach programs and culturally appropriate family and community programs could improve Indigenous dental health in Western Australia, research suggests.
	Vaccine against bird flu tested in humans Together with a team at the Erasmus Medical Center in Rotterdam, LMU researchers have developed a candidate vaccine directed against the avian flu virus H5N1 and have now carried out the first tests in humans.
	'Dramatic' early phase 1 results for AG-120 in IDH1 mutated AML Results presented November 19 by University of Colorado Cancer Center investigator Daniel Pollyea, MD, MS, at the 26th European Organisation for Research and Treatment of Cancer Symposium in Barcelona show "extremely promising" early phase 1 clinical trial results for the investigational drug AG-120 against the subset of patients with acute myeloid leukemia (AML) harboring mutations in the gene IDH1. The finding builds on phase 1 results of a related drug, AG-221, against IDH2 mutations, presented at the most recent meeting of the American Association for Cancer Research. The IDH1 mutation is found in 15-20 percent of all cases of AML, totaling about 3,500 cases of IDH1 AML per year.

	Psychology professor says social validation, meeting expectations among reasons we overeat on Thanksgiving Thanksgiving is a time for family, friends and feasting—lots of feasting. So is it any surprise that our eyes always seem to become so much bigger than our stomachs at this time of year?
Problem gambling, personality disorders often go hand in hand The treatment of people who cannot keep their gambling habits in check is often complicated because they also tend to suffer from personality disorders. So says Meredith Brown of Monash University in Australia, in a review in Springer's Journal of Gambling Studies.
	One-two punch of drugs better than either alone against colorectal cancer Genes make proteins and proteins tell your body's cells what to do: one talks to the next, which talks to the next, and to the next. Like a game of telephone, researchers call these "signaling pathways". Abnormalities in these signaling pathways can cause the growth and survival of cancer cells. Commonly, mutations or rearrangements of genes in the MAPK signaling pathway create cancer's fast growth, and alterations in the PI3K signaling pathway allow cancer cells to survive into virtual immortality.
	Study maps how city neighborhoods affect diabetes risk As the linked epidemics of obesity and diabetes continue to escalate, a staggering one in five U.S. adults is projected to have diabetes by 2050.
	Feeling—not being—wealthy drives opposition to wealth redistribution People's views on income inequality and wealth distribution may have little to do with how much money they have in the bank and a lot to do with how wealthy they feel in comparison to their friends and neighbors, according to new findings published in Psychological Science, a journal of the Association for Psychological Science.
	Few operations for epilepsy despite their safety and efficacy A study at Sahlgrenska Academy, University of Gothenburg, has found that epilepsy surgery is a safe, effective and low-risk procedure. Nevertheless, few Swedes have the operation, and those who are interested may have to wait a long time for presurgical counseling.
Using wash cloths in jails shows promise for reducing costly infections New research shows providing detainees wash cloths treated with a skin cleanser could reduce the prevalence of Staphylococcus aureus (S. aureus) bacteria in U.S. jails. Researchers looked at the effect on transmission of S. aureus of using wash cloths treated with chlorhexidine gluconate (CHG) compared with wash cloths with only plain water in detainees at Dallas County Jail. The study was published in the December issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America (SHEA).
Superbug in SE Michigan shows recent decline A new study finds a decrease in an emergent strain of methicillin-resistant S. aureus (MRSA) that is resistant to last line defense antibiotics. Researchers examined the prevalence of vancomycin-resistant Staphylococcus aureus (VRSA) infections in southeastern Michigan, where the majority of these infections have occurred in the U.S. The study is published in the December issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America (SHEA).

Researchers shed new light on the genetics of memory performance In the largest study of the genetics of memory ever undertaken, an international researcher team including scientists from Boston University School of Medicine (BUSM), have discovered two common genetic variants that are believed to be associated with memory performance. The findings, which appear in the journal Biological Psychiatry, are a significant step towards better understanding how memory loss is inherited.
	Athletes' testosterone surges not tied to winning, study finds A higher surge of testosterone in competition, the so-called "winner effect," is not actually related to winning, suggests a new study of intercollegiate cross country runners.
	Obstructive sleep apnea treatments may reduce depressive symptoms Treatment for obstructive sleep apnea with continuous positive airway pressure (CPAP) or mandibular advancement devices (MADs) can lead to modest improvements in depressive symptoms, according to a study published by Marcus Povitz, Carmelle Bolo, and colleagues from University of Calgary, Canada, in this week's PLOS Medicine.
	Long-term testosterone therapy does not increase the risk of prostate cancer Testosterone (T) therapy is routinely used in men with hypogonadism, a condition in which diminished function of the gonads occurs. Although there is no evidence that T therapy increases the risk of prostate cancer (PCa), there are still concerns and a paucity of long-term data. In a new study in The Journal of Urology, investigators examined three parallel, prospective, ongoing, cumulative registry studies of over 1,000 men. Their analysis showed that long-term T therapy in hypogonadal men is safe and does not increase the risk of PCa.

Reported link between early life exposure to paracetamol and asthma 'overstated' Respiratory infections are likely to have an influential role, the findings suggest. And the evidence is simply not strong enough to warrant changes to current guidance on the use of this medicine, say the researchers.
New insights into breast cancer spread could yield better tests and treatments A study combining tumor cells from patients with breast cancer with a laboratory model of blood vessel lining provides the most compelling evidence so far that a specific trio of cells is required for the spread of breast cancer. The findings could lead to better tests for predicting whether a woman's breast cancer will spread and to new anti-cancer therapies. The study, led by researchers at the NCI-designated Albert Einstein Cancer Center and Montefiore Einstein Center for Cancer Care(MECCC), was published online today in Science Signaling.
Study examines FDA influence on design of pivotal drug studies An examination of the potential interaction between pharmaceutical companies and the U.S. Food and Drug Administration (FDA) to discuss future studies finds that one-quarter of recent new drug approvals occurred without any meeting, and when such meetings occurred, pharmaceutical companies did not comply with one-quarter of the recommendations made by the FDA regarding study design or primary outcome, according to a study in the November 26 issue of JAMA.

Better assessment of decision-making capacity Physicians often find it hard to tell if a patient suffering from dementia or depression is capable of making sound judgements. This is shown by a study conducted within the scope of the National Research Programme "End of Life" (NRP 67). The Central Ethics Committee of the Swiss Academy of Medical Sciences now aims to elaborate new assessment principles.
	Paying attention to what we cook can help reduce food waste Americans waste about 35 million tons of food every year—enough, by some estimates, to fill the Rose Bowl every day. Discarding food squanders natural resources and hurts the environment, as rotting food in landfills is a significant source of methane, a potent greenhouse gas. It squanders money, too. An average family of four throws out between $1,500 and $2,400 worth of food annually.
