New cells found in the retina, paving way for jet lag therapy

The cells of interest in this article express melanopsin receptors. Melanospin receptors detect blue wavelength light (same as the blue sky) and communicate directly to the SCN where it promotes increase in neurohormones such as dopamine, histamine, serotonin and vasopressin which all serve to promote wakefulness and to suppress sleep. Devices having LCD/LED screens (smartphones, tablets, monitors/TVs) emit an intense amount of blue wavelength light. The effect of such blue light exposure lasts 1-3 hours and subsequently the resultant sleep may be unrefreshing. So, in order to prevent sleep disruption, avoid such devices one hour prior to bedtime and dim/turn off other ambient light.

57% of hospital executives rank improving ambulatory access as No. 1 concern

We have a lot of data which indicates it is really not an access issues in metroplex settings (access is more of a factor in rural settings). But, rather, it is an issue of utilization. We can place a clinic on the corner of every block in American and it will not increase utilization. The barrier to healthcare utilization is not an issue of geographic distance, but rather psychological distance. We can place a clinic in everyone's back yard, but psychologically that clinic might as well be on Mars.

New Texas A&M lab gives health research a home

Fantastic new facility for human subject research. I've been working with this team for COPD and obstructive sleep apnea research for some years now with the objective of understanding how to improve quality-of-life and longevity. We are also recruiting patients with dementia and heart failure. We are about to release some amazing findings regarding COPD and muscle mass which is new and bucks the existing science. Enrollment screening for my interested patients is performed through my office.

Trial of new triple inhaler shows 20% reduction in COPD flare-ups

We don't have a "tripple inhaler" on the market yet. But, many with COPD are on these classes of medications through current available options. These maintenance medications are not fast-acting, that is, you may not feel much of a difference today versus tomorrow with use, but they work to stabilize lung function and symptoms over the long term. This means you have to stick with them and compliantly use as prescribed to realize benefit.
