Almost 16,000 COVID-19 patients get hydroxychloroquine and here's what happened

In a new study from Brigham and Women’s hospital, nearly 16,000 patient outcomes were analyzed that were diagnosed with COVID-19 and received the drug hydroxychloroquine.
Instead of improving, patients were four times more likely to experience dangerous heart irregularity, compared to those not teated with the antimalarial drug.
Patients in the study that were given hydroxychloroquine were also more likely to die.
The study is recently published in the medical journal The Lancet  and is the most recent to address a hot topic about whether the medication, which is also prescribed to treat autoimmune disorders, should be  used to treat COVID-19.
Mandeep R. Mehra, a corresponding study author and executive director of the Brigham’s Center for Advanced Heart  Disease said the drug, or any regimen including a chloroquine,  did not help “no matter which way you examine the data.”
Patients from six continents included 
The researchers looked at data from 671 hospitals that included six continents …

Could stress cause obesity?

Researchers from the University of London suggest  long-term stress could be contributing to obesity.
The finding means there may be a way to treat obesity by targeting the stress hormone cortisol.
The paper, published in the journal Obesity, looked at the role of the stress hormone cortisol that is released in response to feeling anxious.
Researchers found people with high levels of the hormone tended to have thicker waistlines and higher body mass index (BMI).
Cortisol plays a role in where fat is stored and can be measured in hair samples.
Lowering stress could help weight loss
Dr Sarah Jackson (UCL Epidemiology and Public Health) who led the research explained in a media release:
"Hair cortisol is a relatively new measure which offers a suitable and easily obtainable method for assessing chronically high levels of cortisol concentrations in weight research and may therefore aid in further advancing understanding in this area."
She adds there was “consistent evidence” that lon…

Self guided positive imagery an easy cost effective way to boost happiness

There is no doubt that happiness is elusive and sometimes seems unattainable. What if a simple thing like training yourself to be happy using imagery actually worked?

Imagery changes brain function for happiness

Researchers say it is entirely possible to be happy by changing the way your brain functions. The technique uses a self-guided approach that you can do at home. It is even a powerful tool for treating PTSD naturally, without drugs and sans a trip to the therapist.

Dr Svetla Velikova of Smartbrain in Norway said in a media release:

"Imagery techniques are often used in cognitive psychotherapy to help patients modify disturbing mental images and overcome negative emotions."

Positive imagery changes brain connections

Velikova  explains reliving negative images in our mind causes anxiety, but  we can transform the brain through positive imagery that focuses on future goals and events.

To test their theory Velikova and co-workers enrolled 30 healthy volunteers in a 2 day wor…
