Immune System Health Is Affected In Space Travel

A new study from Wake Forest Institute for Regenerative Medicine (WFIRM) scientists into the health risks of space radiation exposure shows a potentially greater risk than previously thought. For humans to safely travel into deep space to eventually reach Mars, more understanding is needed about the effects of space travel on their health.

Radiation exposure is believed to be one of the most dangerous aspects of traveling to Mars. The average distance to the red planet is 140 million miles, and a roundtrip could take three years. The latest study was published in a “Stem Cells and Microgravity” special issue of the journal Stem Cells and Development.

Reason Behind Nosebleeds

Nosebleeds, or epistaxes, are often a mystery to the 60% of us who have had at least one in our lifetime. Suddenly, and without obvious cause, bright red blood starts streaming from one nostril. Usually, they're not something to worry about, but why we get them is not always clear.

Causes Of Nosebleeds

The nose is very prone to bleeding. This is because of the important role it plays in warming and humidifying the air we breathe. Large numbers of small blood vessels lie just under a thin layer of skin, as a heat exchange mechanism for air going to the lungs.

Smoking Cessation, Weight Change, Type 2 Diabetes, And Mortality

According to a new study, the researcher examined weight gain after smoking cessation attenuates the health benefits of quitting is unclear. People who gain weight after they quit smoking may face a temporary increase in the risk of developing type 2 diabetes, with the risk directly proportional to the weight gain.

But regardless of weight gain, quitters can reap significant health benefits, including lower risk of cardiovascular disease, cancer, and early death. The study was published in the New England Journal of Medicine.

Cosmetic Treatments Will Give Better Results

A new study has found that people who choose minimally invasive cosmetic procedures do so because they want to feel good, not just look good. For the study, researchers polled roughly 500 U.S. adult patients, most of whom were white women, aged 45 and up. All had undergone some type of relatively non-invasive cosmetic procedure between 2016 and 2017.

The results revealed that nearly seven in 10 chose the procedure to improve their psychological well-being. More than half also wanted to protect their health, boost their confidence levels in a social setting, or look "professional" at work. The study was published in JAMA Dermatology.

Reducing Hospital Emergency Admissions Is Target For All Modern Health Systems

According to a study, the researchers analyzed hospital admissions data for around 65,000 patients diagnosed with bowel cancer between 2011-2013 in the first study of its kind in the UK. Bowel cancer patients living in the most deprived areas have up to 13% higher proportions of emergency hospital admissions before a diagnosis than patients living in the least deprived areas.

The study was published in the British Journal of Cancer, reveals that among the 8,681 patients who died between three and 12 months after a diagnosis, around two thirds (5,809) had an emergency hospital visit before dying. This was around 5% higher among those from more deprived backgrounds.

Association Between Circadian Rhythms And Mood Disorders

Circadian rhythms are regular 24-hour variations in behavior and activity that control many aspects of our lives, from hormone levels to sleeping and eating habits. Circadian rhythms are fundamental to health and are particularly important for mental wellbeing. Disrupted rhythms of rest and activity are recognized as risk factors for major depressive disorder and bipolar disorder.

The study was published in EBioMedicine, follow research published earlier this year in The Lancet Psychiatry which found that disrupted circadian rhythms were associated with increased risk of mood disorders, including major depression and bipolar disorder.
