Patients with multiple sclerosis have higher rates of depression than the general population, including people with other life-long disabling diseases. Symptoms of multiple sclerosis arise from an abnormal response of the body's immune system. Immune response has also been linked to depression, leading researchers to think it could be a shared pathological mechanism that leads to the increased rates of depressive symptoms in patients with multiple sclerosis.
Consistently watching high levels of television during childhood and adolescence were linked with lower peak bone mass at age 20 years in a recent study. Hours of television watching per week were recorded by parental or self-report at 5, 8, 10, 14, 17 and 20 years of age in 1181 participants. Those who consistently watched ?14 hours/week of television had lower bone mineral content than those who watched less television, even after adjusting for height, body mass, physical activity, calcium intake, vitamin D levels, alcohol, and smoking (all at age 20).
A study examined 29 trials assessing the effects of unhealthy food and beverage marketing and analyzing caloric intake and dietary preference among more than 6000 children. Researchers found that the marketing increased dietary intake and influenced dietary preference in children during or shortly after exposure to advertisements.
A recent study in rats suggests that acoustic shock waves could speed up a muscle's healing process. This technique could help injured athletes to return to training and be able to compete more quickly than just with traditional methods.
Machine learning is a type of artificial intelligence that allows computer programs to learn when exposed to new data without being programmed. Now, researchers have coupled machine learning methods with a special MRI technique that measures the perfusion, or tissue absorption rate, of blood throughout the brain to detect early forms of dementia, such as mild cognitive impairment, according to a new study.
Children covered by Medicaid and equally sick children not covered by Medicaid received essentially similar asthma treatment in a given pediatric hospital, according to a new study. In a national sample, researchers analyzed hospital practice patterns by comparing inpatient costs, lengths of stay and use of the intensive care unit.
Mathematicians have shown it is theoretically possible to design ideal climbing ropes to safely slow falling rock and mountain climbers like brakes decelerate a car. They hope someone develops a material to turn theory into reality.
Conventional IVF protocols involve the transfer of a fresh embryo to the uterus during the same cycle in which the eggs were collected and freezing extra embryos for future use. A novel approach to improving IVF outcomes has recently emerged in which all embryos generated from an egg collection cycle are electively frozen and transferred in a subsequent cycle.
