For people who are obese and have type 2 diabetes, weight-loss surgery leads to more than a slimmer figure. It also reduces the risk of heart complications and premature death by about 40% compared to standard medical care, new research says. The Cleveland Clinic researchers compared the impact of various types of weight-loss (bariatric) surgery to usual medical care for people with type 2 diabetes treated between 1998 and 2017. Specifically, they looked at a composite of six components, including death from any cause, heart failure, heart disease, stroke, kidney problems and an irregular heartbeat called atrial fibrillation. “When we looked at the components individually, we saw a reduction in all of those six, including the death rate,” said study lead author Dr. Ali Aminian, a bariatric surgeon at the Cleveland Clinic. Dr. Steven Nissen — chief academic officer of the Heart and Vascular Institute at Cleveland Clinic and senior author of the study — called the findings “striking.” “As a cardiologist, these findings tell me that if we can find a way to get people to lose weight, we can save a lot of lives,” Nissen said. Aminian added that primary care doctors, endocrinologists and cardiologists should regard weight-loss surgery as a tool. “Instead of adding more medications, have a conversation with a bariatric surgeon [about whether surgery would be an appropriate treatment option],”…  read on >

Teen boys who are overweight or obese may be more likely to have a heart attack before they’re old enough to retire, according to a new study. Researchers analyzed data from nearly 1.7 million men in Sweden born between 1950 and 1987 who had extensive physical exams when they entered mandatory military service at age 18. They were tracked for up to 46 years, or to age 64. During that time, more than 22,000 fatal and non-fatal heart attacks were reported in this group, which occurred at an average age of 50. A higher body mass index (BMI) at age 18 was associated with an increased risk of heart attack before age 65, even after the researchers adjusted for other factors. BMI is an estimate of body fat based on height and weight. A BMI of 30 or more is considered obese (for example, someone who’s 5 feet, 10 inches tall and weighs 209 pounds has a BMI of 30). The increased heart attack risk started at BMI 20, which is considered normal, then rose gradually. Men who had been severely obese at age 18 (BMI 35 or higher) had more than triple the risk of heart attack later in life, according to the study presented Tuesday at the European Society of Cardiology’s annual meeting, in Paris. “We show that BMI in the young is…  read on >

Men who are on the blood-thinning drug warfarin have more difficulty taking the medication if they live alone, but the same is not true for women, a new study finds. Warfarin (brand-name Coumadin) is a common anti-clotting treatment to prevent stroke in people with atrial fibrillation, the most common type of heart rhythm disorder. Continuous blood-monitoring is required for warfarin to be safe and effective. Too little of the drug may allow a blood clot to form and cause a stroke. Too much causes bleeding. Having ideal warfarin concentrations in the blood to prevent stroke and avoid bleeding is called time in therapeutic range (TTR). European Society of Cardiology (ESC) guidelines say patients should be in TTR at least 70% of the time. In this study, researchers assessed nearly 4,800 patients in Denmark with six months of continuous warfarin use and monitoring. Median TTR in men living alone was 57% — 3.6% lower than in men who lived with partners. (Median means half had longer times, half shorter.) Women who lived alone had a 0.2% lower TTR than those who lived with partners, but the difference wasn’t significant, according to the study authors. The findings were presented Monday at the annual meeting of the ESC in Paris. Research presented at meetings is typically considered preliminary until published in a peer-reviewed journal. “Men living alone had…  read on >

Driving while high on marijuana can be as dangerous and illegal as driving drunk, but unlike alcohol, there’s no way to detect pot on your breath. That could change, however, as University of Pittsburgh scientists are working hard to develop a breathalyzer that can measure the psychoactive ingredient in pot. Although the technology may work, many questions must be answered before police start checking drivers. “We envision that this sensor can be produced as a breathalyzer like an alcohol breathalyzer,” said lead researcher Alexander Star, a professor of chemistry and bioengineering. As more states legalize pot, it’s likely more drivers will get behind the wheel stoned. Since Washington state legalized marijuana in 2012, the number of drivers involved in fatal crashes who tested positive for marijuana rose from 8% in 2013 to 17% in 2014, according to the National Conference of State Legislatures. Since current testing relies on blood, urine or hair samples, it can’t be done in the field when a driver suspected of being high is pulled over. Using carbon nanotubes, however, Star’s team has found a way of detecting tetrahydrocannabinol (THC), the ingredient in marijuana that creates a high, in a user’s breath. These hollow nanotubes are 100,000 times thinner than a human hair. The electrical components of molecules in the breath bind to the tubes. Since different molecules bind at different…  read on >

When severe storms or hurricanes like Dorian sweep through communities with high winds and flooding, they can leave more than physical damage in their wake. New research suggests that dealing with the aftermath — which can include a damaged home and property — puts people at high risk for depression, anxiety and other mental health problems. “This study shows that exposure to extreme or even moderate weather events may result in ‘psychological casualties,’ with significant impacts on mental health,” said study author Hilary Graham, a professor in the Department of Health Sciences at the University of York in England. “This is reflective of the huge impact storms and flooding have on people’s lives as alongside the physical damage to homes and businesses, there is the emotional damage to the sense of security that many people derive from their home,” Graham explained in a university news release. “With extreme weather events on the rise due to climate change, environmental and health policies need to be brought much more closely together. This means recognizing that flood protection policies are also health protection policies,” Graham said. The level of risk to mental health is similar to that associated with living in a bad neighborhood, and even people whose homes suffer relatively minor damage are at risk for mental health problems, the researchers noted. In the study, they analyzed…  read on >

The overall death rate of the Ebola outbreak in West Africa may have been underestimated, with new research finding survivors could have a five times higher death rate after leaving the hospital than the general population. An outbreak of Ebola is currently raging in the Democratic Republic of Congo, where more than 3,000 cases of the viral disease have occurred over the past year, including more than 2,000 deaths. The new study focuses on 1,130 Guinean survivors of the 2013-2016 Ebola outbreak in West Africa, the largest such outbreak ever recorded. These patients were tracked from early December 2015 to the end of September 2016. During that time, 59 died in the first year after hospital discharge. That 5.2% death rate was five times higher than what would be expected in the general Guinean population, according to the study. It was published Sept. 4 in The Lancet Infectious Diseases journal. “Our findings highlight the need to strengthen Ebola survivor programs, particularly as the number of people surviving the infection are increasing,” study author Dr. Ibrahima Soce Fall said in a journal news release. Fall is the World Health Organization’s assistant director-general for emergency response. Of the 59 deaths, 37 were initially attributed to kidney failure based on symptoms reported by family members. There was a lack of documentation or autopsies available to rule out other…  read on >

Do you ever think that being more at ease at social and business functions could make you happier or possibly help you get ahead at work? Your personality greatly influences your life because it influences so many aspects of your day-to-day world, from personal to business relationships, from your mental to your physical well-being. The Five Traits That Define Personality How outgoing or extroverted you are How open you are to new experiences How agreeable you are How conscientious or self-disciplined you are Your level of emotional stability The old thinking was that your personality was set early in adulthood or even younger. But a research review done at the University of Chicago and published in the journal Psychology Bulletin shed new light on the topic. Researchers looked at information gleaned from 200 studies on mental health treatments ranging from medications to psychotherapy. Though changes in personality weren’t the direct focus of the studies, these changes were revealed when treatment effects were analyzed. The researchers found out that personality traits can change — and change for the better. The reasons study participants had for starting therapy influenced how deep their personality changes were. For instance, people seeking help with emotional stability issues (like anxiety or personality disorders) and those wanting to become less introverted had the deepest changes. People needing help for eating disorders or…  read on >
