Steps For Lifesaving CPR

More than 350,000 people had sudden cardiac arrest outside of a hospital in 2017. Those who received CPR were two to three times more likely to survive. It is a moment everyone hopes they never experience, but it could happen at any time: finding a person in cardiac arrest unconscious and nonresponsive.

Circadian Rhythms Depends On Neuropeptide Release Of VIP SCN Neurons

Scientists unlocked a cure for jet lag in mice by activating a small subset of the neurons involved in setting daily rhythms. The mammalian suprachiasmatic nucleus (SCN) functions as a master circadian pacemaker, integrating environmental input to align physiological and behavioral rhythms to local time cues. The study was published in the journal Neuron.

Approximately 10% of SCN neurons express vasoactive intestinal polypeptide (VIP); however, it is unknown how the firing activity of VIP neurons releases VIP to entrain circadian rhythms. To identify physiologically relevant firing patterns, they optically tagged VIP neurons and characterized spontaneous firing over 3 days.  VIP neurons had circadian rhythms in firing rate and exhibited two classes of instantaneous firing activity.

Motive of International Health NGOs Active in India Questioned

Swadeshi Jagaran Manch alleges many international NGOs such as Bill and Melinda Gates Foundation, Global Health Strategies and Programme for Appropriate Technology for Health are facing the allegations of promoting the interests of certain pharmaceutical companies.

RSS affiliate Swadeshi Jagaran Manch (SJM) has called for a review of the working of international NGOs that are active in Indian health sector for conflict of interest and commercial interests. The organization wanted all state governments and central government to monitor such activities in their respective jurisdictions.

A Step Closer to Predict Epidemics

Ecologists at the University of Georgia have taken an important step in their efforts to develop an early warning system for infectious disease outbreaks.  A team led by Eamon B. O'Dea created a mathematical model that analyzes statistical patterns in public health reports to identify when a population is approaching an epidemic threshold—the point at which a disease outbreak is possible.

Their findings, recently published in the Royal Society journal Interface, help pave the way for a disease forecasting system that could one day be used by public health officials.

Lung Disease and Injury: Synthetic Surfactant Could Ease Breathing

Human lungs are coated with a substance called surfactant which allows us to breathe easily. When lung surfactant is missing or depleted, which can happen with premature birth or lung injury, breathing becomes difficult. In a collaborative study between Lawson Health Research Institute and Stanford University, scientists have developed and tested a new synthetic surfactant that could lead to improved treatments for lung disease and injury. The study is published in Scientific Reports.

New Web-Based Game: People Motivated to Exercise More

A majority of American workers spend most of their day sitting and don't get enough exercise, putting them at risk for a variety of chronic diseases ranging from diabetes to cancer. A team of researchers at the University of Iowa has one potential solution: Turn everyday exercise into a game.

To that end, UI faculty and students designed a web-based game that can be played by anyone with a smartphone and a Fitbit. Those results were published this month in the Journal of the American Heart Association.
