Advice for older adults on staying cool in hot weather : With summer here and the temperatures rising, it is important to understand the health risks that excessive heat can bring and know the signs of heat-related illnesses. Older adults and people with chronic medical conditions are particularly susceptible to hyperthermia and other heat-related illnesses. The National Institute on Aging (NIA), part of the National Institutes of Health, offers advice to help combat the dangers of hot weather.
Immune response linked to Parkinson’s disease : Parkinson’s disease is a degenerative brain disorder that develops when nerve cells in the brain become impaired and eventually die. As these brain cells die, people with Parkinson’s disease may start experiencing involuntary shaking, muscle stiffness, slowed movements, problems with balance, and other symptoms. At first, only a tremor in one hand may be noticeable. As the disease advances, people may have trouble talking, getting dressed, and walking. There’s no cure for the disease, but medicines or surgery can help with managing symptoms.
Gene changes may increase risk of Tourette syndrome : Tourette syndrome is a neurological disorder that is usually diagnosed in childhood. It causes repetitive, involuntary movements or noises called tics. Many with Tourette syndrome experience other problems including inattention, hyperactivity, and impulsivity, as well as obsessive-compulsive symptoms such as intrusive thoughts and worries. Symptoms are usually worst during the early teen years, with improvements for most people in the late teens and early adulthood.
What happens if you stop breathing in your sleep : Most people who have sleep apnea don’t realize it. That’s because this disorder only occurs during sleep.
Sleep apnea is when you have pauses in breathing while you’re asleep. These pauses can last from seconds to minutes. You may have difficulty breathing a few times or dozens of times an hour.
Enzyme drives middle-age weight and fitness changes : Researchers have long known that losing weight and maintaining the capacity to exercise tend to get harder beginning between ages 30 and 40—the start of mid-life. Scientists have developed new therapies for obesity, including fat-fighting pills. However, many therapies have failed because of a lack of understanding about the biological changes that cause middle-aged people to gain weight, particularly around the abdomen.
Neurological issues may drive common voice disorders : Hyperfunctional voice disorders (HVDs) are hard to describe but easy to hear. People with the condition produce a grab-bag of forms of unusual voice behaviors that make them more difficult to follow. Nodules on the vocal cords may trigger the condition, but it may linger after the nodules are removed by surgery. Voice exercises or other treatments sometimes work and sometimes do not.
Trial of Experimental Chikungunya Vaccine Begins : A clinical trial of an experimental vaccine to prevent infection with chikungunya virus is now enrolling healthy adult volunteers at sites in the United States. The Phase 1/2 trial, which is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), is being conducted at several NIAID-funded Vaccine and Treatment Evaluation Units. The candidate vaccine, MV-CHIKV, was developed by Themis Bioscience of Vienna, Austria.
Drinking diet beverages during pregnancy linked to child obesity : Children born to women who had gestational diabetes and drank at least one artificially sweetened beverage per day during pregnancy were more likely to be overweight or obese at age 7, compared to children born to women who had gestational diabetes and drank water instead of artificially sweetened beverages, according to a study led by researchers at the National Institutes of Health. Childhood obesity is known to increase the risk for certain health problems later in life, such as diabetes, heart disease, stroke and some cancers. The study appears online in the International Journal of Epidemiology.
Regular Bedtimes for Children May be Protective Against Obesity : For many generations parenting books and gurus alike have heralded the importance of routine. Beginning in infancy, children are scheduled to eat, sleep and play, and busy moms often follow this schedule to assure their youngest children are happy, healthy and well socialized. But, as is always the case, children grow older and become involved in more activities making it difficult to stick with rigid schedules established in infancy.
Antibodies from Ebola survivor could lead to treatments and vaccines : The 2013-16 Ebola outbreak in West Africa highlighted the need for an effective treatment or vaccine. Researchers have been making progress on several fronts, but many scientific and logistical challenges loom.
Potential predictor of glaucoma damage identified: Glaucoma, a leading cause of blindness worldwide, most often is diagnosed during a routine eye exam. Over time, elevated pressure inside the eye damages the optic nerve, leading to vision loss. Unfortunately, there’s no way to accurately predict which patients might lose vision most rapidly.
Discovery of a Zika antibody offers hope for a vaccine: A research team based at The Rockefeller University has identified a potent new weapon against the Zika virus in the blood of people who have been infected by it. This discovery could lead to new ways of fighting the disease, including a vaccine.
UT Health San Antonio team cures diabetes in mice without side effects: A potential cure for Type 1 diabetes looms on the horizon in San Antonio, and the novel approach would also allow Type 2 diabetics to stop insulin shots.
