Medicine & Health news

	Blood-cleansing biospleen device developed for sepsis therapy Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in a patient's blood—often too fast for antibiotics to help. A new device inspired by the human spleen and developed by a team at Harvard's Wyss Institute for Biologically Inspired Engineering may radically transform the way doctors treat sepsis.
	Neuroscientists identify key role of language gene Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans' unique ability to produce and understand speech.
New study identifies molecule that induces cancer-killing protein A new study by University of Kentucky researchers has identified a novel molecule named Arylquin 1 as a potent inducer of Par-4 secretion from normal cells. Par-4 is a protein that acts as a tumor suppressor, killing cancer cells while leaving normal cells unharmed.
Muscular dystrophy: Repair the muscles, not the genetic defect A potential way to treat muscular dystrophy directly targets muscle repair instead of the underlying genetic defect that usually leads to the disease.

	Genetic testing can identify men at six-fold increased risk of prostate cancer Scientists can now explain a third of the inherited risk of prostate cancer, after a major international study identified 23 new genetic variants associated with increased risk of the disease.
	New drug blocks gene driving cancer growth When active, the protein called Ral can drive tumor growth and metastasis in several human cancers including pancreatic, prostate, lung, colon and bladder. Unfortunately, drugs that block its activity are not available.
	Vitamin E intake critical during 'the first 1,000 days' Amid conflicting reports about the need for vitamin E and how much is enough, a new analysis published today suggests that adequate levels of this essential micronutrient are especially critical for the very young, the elderly, and women who are or may become pregnant.
	Schizophrenia not a single disease but multiple genetically distinct disorders New research shows that schizophrenia isn't a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms. The finding could be a first step toward improved diagnosis and treatment for the debilitating psychiatric illness.
	Zebrafish genes linked to human respiratory diseases A small freshwater fish found in many tropical aquariums may hold the key to unlocking one of the leading causes of respiratory diseases in humans.

In addition to suggesting better treatment options for people with Jacobsen syndrome, the finding also offers more clues into the genetic underpinnings of autism.
Genetics reveals patients susceptible to drug-induced pancreatitis Doctors have discovered that patients with a particular genetic variation are four times more likely to develop pancreatitis if they are prescribed a widely used group of drugs.
	Researchers develop new type of genetic test for identifying developmental disorders (Medical Xpress)—A large team of researchers with members from a host of countries across the globe has conducted an exhaustive study that has resulted in the development of a new genetic test to help identify development disorders in children. In their paper published in the journal Nature Genetics, the researchers describe their study, the results they found and what it might mean for children with development disorders in the near future.
	Cell surface sugars can promote or inhibit cancer depending upon stage During cancer development, tumor cells decorate their surfaces with sugar compounds called glycans that are different from those found on normal, healthy cells. In the Sept. 15 online Early Edition of the Proceedings of the National Academy of Sciences (PNAS), researchers at the University of California, San Diego School of Medicine report that sialic acids at the tips of these cancer cell glycans are capable of engaging with immune system cells and changing the latter's response to the tumor – for good and bad.
	Slow to mature, quick to distract: ADHD study finds slower development of connections A peek inside the brains of more than 750 children and teens reveals a key difference in brain architecture between those with attention deficit hyperactivity disorder and those without.
	Network measures predict neuropsychological outcome after brain injury Cognitive neuroscience research has shown that certain brain regions are associated with specific cognitive abilities, such as language, naming, and decision-making.

One care lapse can be fatal for heart attack patients University of Leeds research has revealed that heart attack patients have a 46% increased chance of death within a month of discharge if they miss any one of nine types of care.
Breast screening for over 70s doesn't prompt sharp fall in advanced disease Including much older women in a national breast cancer screening program does not prompt a sharp fall in new cases of advanced disease in this age group—as would be expected for a successful initiative—reveals a study of the Dutch experience, published in BMJ today.
Experts raise concern over unnecessary treatment of mild hypertension in low risk people Lowering the drug threshold for high blood pressure has exposed millions of low-risk people around the world to drug treatment of uncertain benefit at huge cost to health systems, warn US experts in BMJ today.
Cheaper alternative to licensed drug for treating eye disease has similar side-effects Health policies which favour using ranibizumab for treating eye disease in older people over safety concerns for a cheaper alternative should take account of a new Cochrane Review published today. The researchers looked at the results of studies which compared the safety of two drugs used for treating age-related macular degeneration, ranibizumab and bevacizumab. Contrary to what was argued by some experts the review has found that the cheaper drug, bevacizumab, does not appear to increase deaths or serious side-effects compared with ranibizumab in people with neovascular age-related macular degeneration.
	Walking or cycling to work improves wellbeing, researchers find Walking or cycling to work is better for people's mental health than driving to work, according to new research by health economists at the University of East Anglia and the Centre for Diet and Activity Research (CEDAR).
Health officials warn of Sea-Tac measles exposure Public health officials are warning that people may have been exposed to measles at Seattle-Tacoma International Airport.

Identifying a better message strategy for dissuading smokers: Add the positive Which is more likely to convince a smoker to quit? The words, "Warning: cigarettes cause cancer" beneath the image of an open mouth with a cancerous lesion and rotten teeth, or the same image with the words, "Warning: Quitting smoking reduces the risk of cancer"?
New knowledge of genes driving bladder cancer points to targeted treatments The story of cancer care seems so simple: find the mutated gene that causes cancer and turn it off or fix it. But rarely does a single gene cause cancer. More often, many genes are altered together to drive the disease. So the challenge becomes sorting out which altered genes are the most to blame in which cancers. A collaborative study between researchers at the University of Colorado Cancer Center and the National Cancer Institute (NCI) published today in the journal Clinical Cancer Research takes an important step toward answering this question in bladder cancer.
	Marijuana users who feel low get high Adolescents and young adults who smoke marijuana frequently may attempt to manage negative moods by using the drug, according to a study in September's Journal of Studies on Alcohol and Drugs.
Hypersensitivity to non-painful events may be part of pathology in fibromyalgia New research shows that patients with fibromyalgia have hypersensitivity to non-painful events based on images of the patients' brains, which show reduced activation in primary sensory regions and increased activation in sensory integration areas. Findings published in Arthritis & Rheumatology, a journal of the American College of Rheumatology (ACR), suggest that brain abnormalities in response to non-painful sensory stimulation may cause the increased unpleasantness that patients experience in response to daily visual, auditory and tactile stimulation.
	New drug formulations to boost fight against respiratory illnesses and antibiotic-resistant superbugs A team of five researchers and clinicians in Singapore led by Dr Desmond Heng, ICES, has developed a new combination of drugs to effectively combat bacteria in the lungs which lead to common respiratory system infections, or bacteria-linked pulmonary diseases such as pneumonia, bronchiectasis and cystic fibrosis.
New study looks at improving vaccine awareness The best medical therapies won't do much good if the public abstains from using them. Resistance to life-saving interventions may have a variety of root causes, particularly if the biotechnology involved is new and poorly understood in the non-medical community.
	The public's perception of the obesity epidemic Obesity has been called a major health crisis and a national epidemic. Health authorities, including prominent spokespeople like Michelle Obama and the Surgeon General, have sounded the alarm, and the media have responded with a bombardment of stories about the state of the nation's waistline.
	Gilead to license generic version of Sovaldi (Update) Gilead Sciences has reached a deal with several generic drugmakers to produce a cheaper version of its popular, $1,000-per-pill hepatitis C drug Sovaldi for use in developing countries.

The vaccine is a promising candidate for immunizing camels, thought to be the source of human infection.
	Breaking down experiences into million parts may help explain consciousness Take the screen on which you are reading this article. When you look at it, you see one complete scene, but you know that this scene is composed of millions of pixels that only come in three colours: red, blue and green. When you look out at the world, you see one integrated landscape, whole and complete. But what if like every other biological system, this conscious experience too has its basic building blocks? I ask this question because, despite decades of research, consciousness remains an unexplained phenomenon. Perhaps thinking of consciousness as being made of bits of awareness is the solution.
As kids get older, snacks get poorer American kids snack about three times a day on average, totaling about a third of their daily calorie count. But whether those snacks are good choices has a lot to do with the child's age, according to a new study.
	Abhor asparagus and can't stand coffee? You may be a supertaster There are natural variations between humans in our senses. We need different prescriptions to correct our eyesight. Some people say that vinyl sounds better than CDs or MP3s and will pay big money for audio equipment, while others can't tell the difference.
Ovarian cancer remains elusive to early diagnosis and successful treatment A population-based study of all ovarian cancer cases diagnosed in Australia in 2005 found a crude five year survival rate of 35 per cent.
	Conservation versus innovation in the fight against antibiotic resistance "Antibiotic resistance is a problem of managing an open-access resource, such as fisheries or oil," writes Ramanan Laxminarayan, a research scholar at Princeton University and the director of the Center for Disease Dynamics, Economics & Policy in Washington, D. C., in today's issue of the journal Science. He goes on to say that individuals have little incentive to use antibiotics wisely, just as people have little incentive to conserve oil when it is plentiful.
A qualitative analysis of 'informed choice' among young adult smokers Flaws in the tobacco industry's argument that smokers exercise "informed adult choice" when they start smoking have been highlighted in new study.
New drug target could prevent major global cause of maternal death (Medical Xpress)—Researchers at the University of Warwick have discovered a new target for drugs that could prevent the deaths of thousands of women in the developing world due to heavy blood loss after childbirth.
	New glaucoma culprit is found Glaucoma, a leading cause of irreversible blindness, is associated with elevated pressure in the eye. This elevated pressure essentially is due to a plumbing problem. Fluid builds up in the eye, increasing pressure and eventually damaging the optic nerve. For nearly 150 years, researchers have been trying to understand what causes the blockage that prevents the eye from draining properly.
Some lung cancer patients could live longer when treated Treating advanced small-cell lung cancer (SCLC) with thoracic (or chest) radiation therapy in addition to standard treatment significantly prolongs long-term survival and reduces cancer recurrence in the chest by almost 50%, according to new research published in The Lancet and being presented simultaneously at ASTRO's 2014 Annual Meeting in San Francisco.
	Breakthrough in detecting early onset of refractory epilepsy in children 65 million people around the world today suffer from epilepsy, a condition of the brain that may trigger an uncontrollable seizure at any time, often for no known reason. A seizure is a disruption of the electrical communication between neurons, and someone is said to have epilepsy if they experience two or more unprovoked seizures separated by at least 24 hours.
Advancing the science for health programming in crisis conditions Humanitarian crises are becoming increasingly complex and a growing threat to the health and safety of populations. An improved evidence-base to guide interventions in the countries most vulnerable to these conditions is more critical than ever. A paper by researchers at Columbia University's Mailman School of Public Health published online in the journal Science, looks at the challenges of doing research in such settings and the strategies that must be adopted for scientific advance.
	Researchers discover the healing power of 'rib-tickling' Unlike salamanders, mammals can't regenerate lost limbs, but they can repair large sections of their ribs.
	Lessons from the war on terror could help the war on cancer There may seem to be no connection between terrorism and cancer. But that is an oversight. If considered closely, it is easy to see that both exhibit loss of control present in "normal" conditions and are often detected only when they have already invaded and spread to different sites.
T-bet tackles hepatitis A single protein may tip the balance between ridding the body of a dangerous virus and enduring life-long chronic infection, according to a report appearing in The Journal of Experimental Medicine.
	Study finds young women involve parent in abortion when anticipating support When an adolescent wants to terminate a pregnancy, how does she decide whether to talk to a parent? A recent study from the Section of Family Planning and Contraceptive Research at the University of Chicago found that pregnant teens will turn to parents and adults who are engaged in their lives and who will offer support, regardless of her pregnancy decision. Young women will avoid talking with parents who are less involved or may try to prevent them from seeking care.
	One in five men reports violence toward intimate partners One in five men in the U.S. reports violence towards their spouse or significant other, says a new nationally-representative study by the University of Michigan.

Strategic self-sabotage? MRSA inhibits its own growth Scientists at the University of Western Ontario have uncovered a bacterial mystery. Against all logic, the most predominant strain of methicillin-resistant Staphylococcus aureus (MRSA) in North American produces an enzyme that degrades skin secretions into compounds that are toxic to itself. The research is published online ahead of print in the Journal of Bacteriology.
Congenital and genetic heart disease screening recommendations for people 12-25 Healthcare professionals should include 14 key elements that can be used as a checklist for screening young people age 12-25 for congenital and genetic heart disease. If any of the elements are positive, further testing may be needed, but initial screening using electrocardiograms (ECG) to detect underlying genetic and congenital heart disease in this age group prior to employing this checklist, has not been shown to save lives, according to a joint American Heart Association/American College of Cardiology statement.
What's more effective: Generic or brand-name statins? Statins are the most frequently prescribed drugs in the United States and are effective in reducing cardiovascular events. However, evidence suggests that patients do not always take these medications as prescribed and may not receive their full benefit. Researchers from Brigham and Women's Hospital (BWH), Harvard Medical School and CVS Health investigated whether the use of generic versus brand-name statins can play a role in medication adherence and whether or not this leads to improved health outcomes. They found that patients taking generic statins were more likely to adhere to their medication and also had a significantly lower rate of cardiovascular events and death. These findings are published in the Annals of Internal Medicine on September 15, 2014.
Predicting prostate cancer: Test identifies new methods for treatment A genetic discovery out of the University of Pittsburgh School of Medicine is leading to a highly accurate test for aggressive prostate cancer and identifies new avenues for treatment.
Largest ever study of awareness during general anaesthesia identifies risk factors, consequences Accidental awareness is one of the most feared complications of general anaesthesia for both patients and anaesthetists. Patients report this failure of general anaesthesia in approximately 1 in every 19,000 cases, according to a report published in Anaesthesia. Known as accidental awareness during general anaesthesia (AAGA), it occurs when general anaesthesia is intended but the patient remains conscious. This incidence of patient reports of awareness is much lower than previous estimates of awareness, which were as high as 1 in 600.
	Cellular protein may be key to longevity Researchers have found that levels of a regulatory protein called ATF4, and the corresponding levels of the molecules whose expression it controls, are elevated in the livers of mice exposed to multiple interventions known increase longevity.
Delay in age of walking can herald muscular dystrophy in boys with cognitive delays The timing of a toddler's first steps is an important developmental milestone, but a slight delay in walking is typically not a cause of concern by itself.

	Study finds drop in death rates from strokes over last two decades Despite the significant reduction in the overall incidence and death rates from strokes in the United States over the past twenty years, more attention needs to be paid to specific age groups, a recent study found.
Caregivers of family members newly diagnosed with mental illness at risk for anxiety Researchers at Case Western Reserve University School of Nursing, who studied the emotional distress of caring for a family member diagnosed with a mental illness, found anxiety is high for the primary caregiver at the initial diagnosis or early in the course of the illness and decreases over time.
Scientists identify the master regulator of cells' heat shock response Heat shock proteins protect the molecules in all human and animal cells with factors that regulate their production and work as thermostats. In new research published Sept. 16 in the journal eLife, scientists at NYU Langone Medical Center and elsewhere report for the first time that a protein called translation elongation factor eEF1A1 orchestrates the entire process of the heart shock response. By doing so, eEF1A1 supports overall protein homeostasis inside the cell, ensuring that it functions properly under various internal and external stress conditions. The researchers suggest that this finding could reveal a promising, new drug target for neurodegenerative diseases and cancer.
	Long-term effects of childhood asthma influenced by socioeconomic status According to the Centers for Disease Control and Prevention (CDC), approximately 6 percent of children younger than five have been diagnosed with asthma, the fastest-growing and most common chronic illness affecting children in the United States. Studies have shown that asthma is associated with attention and behavioral issues in children, yet little existing research examines how socioeconomic status may influence the ultimate effects of these difficulties. Now, an MU researcher has found that the overall outcomes for children with asthma are influenced by socioeconomic inequalities.
Researchers develop improved means of detecting mismatched DNA Researchers at Johns Hopkins have identified a highly sensitive means of analyzing very tiny amounts of DNA. The discovery, they say, could increase the ability of forensic scientists to match genetic material in some criminal investigations. It could also prevent the need for a painful, invasive test given to transplant patients at risk of rejecting their donor organs and replace it with a blood test that reveals traces of donor DNA.
Freshman girls know how to eat healthy but lack confidence in their ability to do it Female college freshmen understand the benefits of eating healthy foods and know which foods they should include in their diets. But they lack confidence in their ability to act on that knowledge, especially when it comes to getting enough calcium, says a new University of Illinois study.
	Number-crunching could lead to unethical choices, study shows Calculating the pros and cons of a potential decision is a way of decision-making. But repeated engagement with numbers-focused calculations, especially those involving money, can have unintended negative consequences, including social and moral transgressions, says new study co-authored by a professor at the University of Toronto's Rotman School of Management.
Combining epilepsy drug, morphine can result in less pain, lower opioid doses Adding a common epilepsy drug to a morphine regimen can result in better pain control with fewer side effects.

Web-based training can reduce campus rape Web-based training targeted at college-aged men is an effective tool for reducing the number of sexual assaults on U.S. campuses, according to a researcher in the School of Public Health at Georgia State University.
Researchers urge psychologists to see institutional betrayal Clinical psychologists are being urged by two University of Oregon researchers to recognize the experiences of institutional betrayal so they can better treat their patients and respond in ways that help avoid or repair damaged trust when it occurs in their own institutions.
	Researcher develops, proves effectiveness of new drug for spinal muscular atrophy According to recent studies, approximately one out of every 40 individuals in the United States is a carrier of the gene responsible for spinal muscular atrophy (SMA), a neurodegenerative disease that causes muscles to weaken over time. Now, researchers at the University of Missouri have made a recent breakthrough with the development of a new compound found to be highly effective in animal models of the disease. In April, a patent was filed for the compound for use in SMA.
	EEG study findings reveal how fear is processed in the brain An estimated 8% of Americans will suffer from post traumatic stress disorder (PTSD) at some point during their lifetime. Brought on by an overwhelming or stressful event or events, PTSD is the result of altered chemistry and physiology of the brain. Understanding how threat is processed in a normal brain versus one altered by PTSD is essential to developing effective interventions.
Certain form of baldness at age 45 linked to higher risk of aggressive prostate cancer A new, large cohort analysis from the prospective Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial, indicates that men who had moderate baldness affecting both the front and the crown of their head at age 45 were at a 40% increased risk of developing aggressive prostate cancer (usually indicates a faster growing tumor resulting in poorer prognosis relative to non-aggressive prostate cancer) later in life, compared to men with no baldness. There was no significant link between other patterns of baldness and prostate cancer risk. The study, published September 15 in the Journal of Clinical Oncology, supports earlier research suggesting that male pattern baldness and prostate cancer may be linked.
Multiple-birth infants use more resources, spotlight on reproductive technology Hospital costs are higher and the odds of complication and death are greater for multiple-birth infants than singleton births and some of this clinical and economic burden can be alleviated through single-embryo transfer in assisted reproductive technology (ART).
The 'hidden injury' in sports: research sheds light on concussions Star receiver Charles-Antoine Sinotte suffered a concussion during his last home game for the McGill Redmen in 2010. "It was like nothing I had experienced before," recalls Sinotte. "I felt like I was out of my body." Although he received medical attention and missed the rest of the game, he admits he downplayed his symptoms in order to play in the next game – his last before leaving McGill.
Study adds to cancer-fighting promise of combined immunotherapy-radiation treatment A study in mice implanted with breast and melanoma cancers adds to a growing body of evidence that highly focused radiation – long thought to suppress immunity – can actually help boost the immune system's fight against cancer when combined with a new kind of immune-enhancing drug.
	Study first to use brain scans to forecast early reading difficulties UC San Francisco researchers have used brain scans to predict how young children learn to read, giving clinicians a possible tool to spot children with dyslexia and other reading difficulties before they experience reading challenges.

Mayo finds many liver transplant patients can avoid costly stay in ICU after surgery The liver transplant team at Mayo Clinic in Florida has found, based on 12 years of experience, that more than half of patients receiving a new liver can be "fast-tracked" to return to a surgical ward room following their transplant, bypassing a one- or two-day stay in the Intensive Care Unit (ICU).
AGA releases new tool to help GIs evaluate and treat Crohn's disease The treatment of Crohn's disease is evolving. To help gastroenterologists better identify and manage their Crohn's disease patients, the American Gastroenterological Association (AGA) has created a clinical decision tool to guide GIs in their decision-making process. The "Identification, Assessment, and Initial Medical Treatment in Crohn's Disease Clinical Decision Support Tool," published in Gastroenterology, the official journal of the AGA, synthesizes gastroenterologist's understanding of the disease with data from recent studies to create a pathway for GIs to follow in assessing and treating their patients.
Case studies challenge students to diagnose infectious diseases For almost 25 years, medical students have relied on Cases in Medical Microbiology and Infectious Diseases to prepare for Part I of the National Board of Medical Examiners Exam. First published in 1992, the newly updated, fourth edition, now available from the American Society for Microbiology (ASM) Press, continues to challenge students to develop a working knowledge of the variety of microorganisms that cause infections in humans.
Re-expression of an embryonic signaling pathway in melanoma utilizes different receptors Metastatic melanoma is a highly aggressive skin cancer whose incidence is on the rise at an alarming rate. Research has revealed that metastatic tumor cells share similar signaling pathways with embryonic stem cells to sustain plasticity and growth. However, major regulators of these pathways are often missing in tumor cells, thus allowing uncontrolled tumor growth and spreading to occur.
Gut bacteria tire out T cells Leaky intestines may cripple bacteria-fighting immune cells in patients with a rare hereditary disease, according to a study by researchers in Lausanne, Switzerland.

Shorter course of ADT for high-risk prostate cancer patients yields improved quality of life High-risk prostate cancer patients who receive radiation therapy (RT) and an 18-month course of androgen deprivation therapy (ADT) recover a normal testosterone level in a shorter amount of time compared to those who receive a 36-month course of ADT, thus resulting in a better quality of life (QOL) and without detriment to long-term outcomes, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 56th Annual Meeting.
Blood test for VEGF-A, TGF-B1 could help determine treatment options for esophageal cancer patients A blood test may be beneficial in indicating neoadjuvant treatment regimens for patients with esophageal squamous cell carcinoma (ESCC), according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 56th Annual Meeting. Results of a nine-year study of patients undergoing concurrent chemotherapy and radiotherapy (CCRT) for esophageal cancer show that levels of two proteins found in the body, vascular endothelial growth factor-A (VEGF-A) and transforming growth factor-β1 (TGF-β1), indicate patients' pathological response and disease-free survival rates.
Patient-reported data shows RT does not increase risk of lymphedema in node-negative BC patients A secondary analysis of the National Surgical Adjuvant Breast and Bowel Project B-32 trial (Krag 2010) indicates that radiation therapy (RT) does not increase the incidence of lymphedema in patients with node-negative breast cancer, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 56th Annual Meeting.
Manuka honey does not decrease pain of radiation-induced esophagitis for lung cancer patients Patient-reported data indicates that when Manuka honey is prescribed for esophagitis pain during radiation therapy (RT), it is not more effective than standard medical care, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 56th Annual Meeting.
