The social psychology of nerve cells

The social psychology of nerve cells

The functional organization of the central nervous system depends upon a precise architecture and connectivity of distinct types of neurons. Multiple cell types are present within any brain structure, but the rules governing their positioning, and the molecular mechanisms mediating those rules, have been relatively unexplored. A new study by UC Santa Barbara researchers demonstrates that a particular neuron, the cholinergic amacrine cell, creates a “personal space” in much the same way that people distance themselves from one another in an elevator.

Nearly four percent of U.S. babies born before full-term without medical reason

Nearly four percent of U.S. babies born before full-term without medical reason

New University of Minnesota research out this week is the first of its kind to show who is having early elective deliveries between 37 and 39 weeks gestation, and whether these deliveries happen following labor induction or cesarean. Labor induction or cesarean delivery without medical reason before a baby is considered full-term at 39 weeks, or an “early elective delivery,” is associated with health problems for mothers and babies. The study, led by University of Minnesota School of Public Health Assistant Professor Katy Kozhimannil, Ph.D., M.P.A., in collaboration with Children’s Hospital of Philadelphia researchers Michelle Macheras, M.A., and Scott A Continue reading

Exploring how the nervous system develops

Exploring how the nervous system develops

The circuitry of the central nervous system is immensely complex and, as a result, sometimes confounding. When scientists conduct research to unravel the inner workings at a cellular level, they are sometimes surprised by what they find. Continue reading

Restoring trust in VA health care

Restoring trust in VA health care

In the wake of recent revelations of overly long patient wait times and systematic manipulation and falsification of reported wait-time data, UC Davis and Harvard public policy leaders believe the Department of Veterans Affairs (VA) health-care system’s problems can be fixed by strong leadership, greater transparency and reforms that refocus the organization on its primary mission of providing timely access to consistently high-quality care. In their Perspective article, published online in the New England Journal of Medicine , authors Kenneth W. Kizer and Ashish K Continue reading

When hospital workers get vaccines, community flu rates fall, study shows

For every 15 healthcare providers who receive the influenza vaccination, one fewer person in the community will contract an influenza-like illness, according to a study using California public health data from 2009 — 2012. Continue reading

Lasers, night-vision technology help improve imaging of hidden lymphatic system

Lasers, night-vision technology help improve imaging of hidden lymphatic system

The human lymphatic system is an important but poorly understood circulatory system consisting of tiny vessels spread throughout the body. This “drainage” network helps guard against infections and prevents swelling, which occasionally happens when disease or trauma interrupts normal lymphatic function. Chronic swelling is the hallmark of a painful, incurable condition known as lymphedema, which often occurs after cancer therapy and can leave the limbs and other body parts disfigured for life.

Public reporting of ICU mortality does not improve outcomes

Public reporting of ICU mortality does not improve outcomes

A large study of intensive care patients in California found that public reporting of patient outcomes did not reduce mortality, but did result in reduced admission of the sickest patients to the ICU and increased transfer of critically ill patients to other hospitals. “Public reporting is designed to reduce mortality by steering patients towards high-quality hospitals and creating incentives for hospitals to adopt quality improvement programs,” said Lora Reineck, MD, a postdoctoral scholar at the University of Pittsburgh.
