Association Between Orthostatic Hypotension And CVD

The team analyzed data from 9,139 participants ages 45 to 64 who enrolled in the long-running Atherosclerosis Risk in Communities (ARIC) Study between 1987 and 1989. These participants were followed for cardiovascular events and mortality. Orthostatic hypotension (OH), a rapid drop in blood pressure upon standing up from a sitting or lying down position is a frequently encountered clinical sign among patients.

Clinicians most often consider OH as indicative of dehydration. However, new research led by scientists at BIDMC bolsters the notion that adults with OH may have the undiagnosed cardiovascular disease. The study was published online in the Journal of the American Heart Association.

Pcychological Impact Of Life Stress And Parental Separation

In a recent study, the researchers showed that more than 2,000 migrant children have been separated from their families at the United States/Mexico border. Questions about the policy, including how it affects the children's well-being, has led to a suspension of the practice.

For these children, family separation is an additional trauma to an already adverse experience in their home environments and a long, difficult journey to the United States. Even after families are reunited, the uncertainty surrounding these parents' lives could exacerbate feelings of anguish, despair, guilt, blame, and depression negative emotions that disrupt how they learn life skills.

Physical Activity: Physically Demanding Jobs Shorten Men's Lives

Despite much evidence that getting lots of physical activity bodes well for long-term health when it's physical labor on the job, the opposite might be true. Researchers found that men whose jobs involve a lot of physical labor are 18% more likely to die prematurely than workers who sit at desks most of the day.

Brain Clock During Sleeping Hours

Researchers have found that it is the collection of certain proteins in the brain that triggers our desire to turn in. This new understanding could offer a new target for drugs to treat insomnia and other sleep disorders. They have discovered what happens in the brain when we get sleepy. 

They all need sleep to survive, but mystery still surrounds much of our nightly shut-eye. It is not clear what it does to the body or why we need it. 

1. Proteins in the brain track synaptic activity, acting like a countdown clock

2. Chemical tags gather on these proteins throughout the day and fall off at night

3. Researchers at the University of Texas say that these maintain wake-sleep balance

4. Targeting these proteins could someday offer a  treatment for sleep disorders
