Healthy diet, healthy eyes

(HealthDay)—Healthy eating may help preserve your vision as you age, eye experts say. Age-related macular degeneration (AMD) damages the macula (a small area near the center of the retina, located on the inside back layer of the eye), leading to a decline in central vision. There is no cure for AMD, which affects about 10

More cases in E. coli outbreak tied to romaine lettuce

(HealthDay)—The outbreak of E. coli illness tied to tainted Arizona romaine lettuce continues to expand, federal health officials said Wednesday. “Since the last update on April 13, 2018, 18 more ill people have been added to this investigation, bringing the total number to 53,” the U.S. Centers for Disease Control and Prevention said in a

Elevation in buildings can affect the decisions we make

People rely on financial managers, doctors and lawyers to be as objective as possible when making decisions about investments, health and legal issues, but findings from a new study suggest that an unexpected factor could be influencing these choices. In a series of experiments, researchers found that people at higher elevations in an office building

Time-related deployment factors predict suicide attempt risk

(HealthDay)—For soldiers who have been deployed twice, suicide attempt (SA) risk is associated with timing of first deployment and dwell time (DT; i.e., length between deployments), according to a study published online April 18 in JAMA Psychiatry. Robert J. Ursano, M.D., from the Uniformed Services University of the Health Sciences in Bethesda, Md., and colleagues

Gene variant increases empathy-driven fear in mice

Researchers at the Center for Cognition and Sociality, within the Institute for Basic Science (IBS), have just published in Neuron about a genetic variant that controls and increases empathy-driven fear in mice. As empathy is evolutionarily conserved from rodents to humans, this finding might contribute to clarify individual variability in neuropsychiatric conditions characterized by empathic

Delayed coronary obstruction rare after TAVR

(HealthDay)—Delayed coronary obstruction (DCO) after transcatheter aortic valve replacement (TAVR) is a rare phenomenon but is associated with a high in-hospital mortality rate, according to a study published in the April 10 issue the Journal of the American College of Cardiology. Richard J. Jabbour, M.D., from Imperial College London, and colleagues used a large international

Changing how blood pressure is measured will save lives

Traditional methods of testing for high-blood pressure are no longer adequate and risk missing vital health signs, which can lead to premature death, a study co-led by UCL has found. The research, the largest ever cohort study of its kind, published in the New England Journal for Medicine, assessed 63,000 doctors’ patients, who had their

Pathways to spatial recognition

When you are lost or disoriented, your brain uses cues from your surroundings—landmarks both near and far—to sort out where you are. The information gathered by your senses is transmitted by nerve cells, or neurons, to specific brain regions where the signal is routed through circuits and sent downstream to areas that essentially translate the

Study predicts 2018 flu vaccine will have 20 percent efficacy

A Rice University study predicts that this fall’s flu vaccine—a new H3N2 formulation for the first time since 2015—will likely have the same reduced efficacy against the dominant circulating strain of influenza A as the vaccine given in 2016 and 2017 due to viral mutations related to vaccine production in eggs. The Rice method, known

Pregnant moms and their kids should limit added sugars to protect childhood cognition

A new study published in the American Journal of Preventive Medicine has determined that poorer childhood cognition occurred, particularly in memory and learning, when pregnant women or their offspring consumed greater quantities of sugar. Substituting diet soda for sugar-sweetened versions during pregnancy also appeared to have negative effects. However, children’s fruit consumption had beneficial effects

Study shows creativity is state of mind that can be trained

As an undergraduate student at York University, Joel Lopata was studying film production and jazz performance when a discrepancy became apparent. “I noticed students in the jazz program were really developing a language of creative engagement, whereas in the film program, we weren’t having the same education. It was a lot more theoretical than practical,

Researchers report on tumor transition states

Tumor heterogeneity describes the differences between different cells within a given tumor. These differences have major implications for the diagnosis, prognosis, and therapy of cancer patients. Different mechanisms have been proposed to account for tumor heterogeneity such as epithelial to mesenchymal transition (EMT), a process in which epithelial tumor cells loose their adhesion and acquire

Aspirin may reduce cardiovascular risk during bereavement

An investigation that has appeared in the current issue of Psychotherapy and Psychosomatics suggests that low-dose aspirin may have a role in the prevention of cardiovascular risk associated with bereavement. In the 24 h following the death of a significant person, the incidence of acute myocardial infarction increases 21.1-fold. Low-dose aspirin could be a suitable

How bone marrow niches keep stem cells thriving

Hematopoietic stem cells (HSCs) are a class of stem cells located in bone marrow. HSCs give rise to every type of blood cell—from the red blood cells that carry oxygen to the white blood cells of the immune system. Bone marrow provides a niche that both houses and regulates HSCs to ensure proper formation of

Enduring cold temperatures alters fat cell epigenetics

A new study in fat cells has revealed a molecular mechanism that controls how lifestyle choices and the external environment affect gene expression. This mechanism includes potential targets for next-generation drug discovery efforts to treat metabolic diseases including diabetes and obesity. Researchers tracked how the epigenome changes after long-term exposure to cold temperatures, and how

Spectacle lens slows myopic progression by 60 percent

The Defocus Incorporated Multiple Segments (DIMS) Spectacle Lens developed by the Hong Kong Polytechnic University (PolyU) slowed down myopia progress by 60 percent in participating children; myopic progression halted completely in 21.5 percent of subjects. This lens will be launched in summer 2018, offering a non-contact, spectacle lens solution to myopic children. The lens was

In Romania, distrust of vaccines kills

Measles still claims young lives in Romania, where nearly 40 children have died in an outbreak that many blame on parents being misled by scare stories that vaccinating them is dangerous. Some 12,000 people have contracted measles since late 2016 in the European Union’s second-poorest country, 46 of them died. Among the dead, 39 were
