Space Travel May Lead To Cardiac Repair In Astronauts

Astronauts live in a practically weightless environment, scientifically known as microgravity. The effects of microgravity on the human body are various and fascinating some of them damaging, some redeeming.

New research finds a therapeutic purpose for the impact of microgravity on human stem cells. The study was published in the journal  Stem Cells and Development. From the brain shifting upward to muscles shrinking, veins swelling, and astronauts' faces getting puffy, the effects of microgravity on the human body are fascinating.

Generation Of Heart Risk Factors May Decrease Brain Function

It's been 70 years since a small, middle-class community 23 miles west of Boston became the linchpin in helping to solve the mysteries of heart disease.  Cholesterol Blood pressure. Obesity It's common knowledge today that these all lead to heart trouble.

But in the 1940s, with one in two deaths caused by cardiovascular disease and even after President Franklin Roosevelt died from the effects of heart failure and a massive stroke, the information would have been considered revolutionary.

Applications Of Nanoparticles In Tissue Engineering

Tissue engineering (TE) is an interdisciplinary field integrating engineering , material science and medical biology that aims to develop biological substitutes to repair, replace, retain, or enhance tissue and organ-level functions.

Current TE methods face obstacle including a lack of appropriate biomaterials, ineffective cell growth and lack of techniques for capturing appropriate physiological architectures as well as the unstable and insufficient production of growth factors to stimulate cell communication and proper response.

Improper Treatment Of Hearing Loss Tied To Cognitive Decline In Older Adults

Researchers examined data on 7,385 adults 50 and older without a diagnosis of dementia or other conditions tied to cognitive problems and without hearing implants or ear infections. Overall, about 41% had a mild hearing loss, 10% had a severe hearing loss, and 11% used a hearing aid. 

While age-related hearing loss has been linked to cognitive decline. The study suggests hearing aids may help minimize the risk of problems like impaired memory or executive function. People in the study who used hearing aids, however, were very different from those who did not use these devices.

The study was published in JAMA Otolaryngology-Head and Neck Surgery.

Diabetic Patients Die From Alcohol-Related Factors/Accidents

Diabetic patients are more likely to die from alcohol-related factors, accidents or suicide. The study was published in the  European Journal Endocrinology. The study findings suggest that the increased risk of death from these causes may be related to the mental health of patients, which may be adversely affected by the psychological burden of living with and self-treating this debilitating disease, with powerful and certain disorders.

Doubly Randomized Preference Trial of Prolonged Exposure Versus Sertraline for Treatment of PTSD

A multiyear clinical trial comparing medication and mental health in the treatment of post-traumatic stress disorder shows that patients who chose their form of treatment-whether drugs or therapy improved more than those who were simply prescribed one or the other regardless of the patient's preference. The study was published in the  American Journal of Psychiatry.

This is the first large-scale trial of hundreds of PTSD patients, including veterans and survivors of sexual assault, to measure if a patient preference in the course of treatment with the effectiveness of a type of cognitive behavioral therapy and use of selective serotonin reuptake inhibitors, a type of antidepressant often prescribed for PTSD.
