Ebola Patient Ian Crozier and Physicians to Speak About Unexpected, Vision-Threatening Consequences for Ebola Virus Survivors

on .

Ian Crozier, an infectious disease specialist, signed on with the World Health Organization and arrived in Kenema, Sierra Leone to help in the fight against the Ebola outbreak in August 2014. Within a few weeks, he himself contracted the disease and was evacuated to Emory University Hospital in Atlanta in critical condition. Crozier and physicians will share their perspective at ARVO 2015 closing session.

UTHealth Researchers Use 'Knockout Humans' to Connect Genes to Disease Risk

on .

Newswise imageResearchers at The University of Texas Health Science Center at Houston (UTHealth) are helping to make precision medicine a reality by sequencing entire exomes of people to assess chronic disease risk and drug efficacy. The results of a study on this topic were published in Nature Genetics on Monday.

Novel Approach Blocks Amyloid Production in Alzheimer's Mouse Model

on .

Offering a potential early intervention for Alzheimer's disease (AD), researchers at University of California, San Diego School of Medicine and Cenna Biosciences, Inc. have identified compounds that block the production of beta amyloid peptides in mice.

Combined Chemotherapy and Immunotherapy Shows Promise for Advanced Prostate Cancers

on .

Researchers at the University of California, San Diego School of Medicine report that blocking or removing immune-suppressing cells allows a special type of chemotherapy -- and the immune cells it activates -- to destroy prostate tumors. This novel combination therapy, termed chemoimmunotherapy, achieved near complete remission in mouse models of advanced prostate cancer. The study is published April 29 in Nature.

5-Year Survivors of Esophageal Cancer Still Face Low But Constant Risks

on .

According to the American Cancer Society, in 2015 about 17,000 new cases of esophageal cancer will be diagnosed, and about 15,600 people will die from the disease. While the 5-year survival rate in the 1960s and 1970s was only about 5%, improvements in diagnosis, treatment, and management have led to improved survival. However, information is lacking about what happens to long-term survivors of esophageal cancer. A presentation at the AATS Annual Meeting shows that while five-year survival is up to 39%, these patients still face many health risks and should be monitored for 10 years or more.

Why Do Obese Men Get Bariatric Surgery Far Less Than Women?

on .

Newswise imageA new study by researchers at the University of California, San Diego School of Medicine has identified demographic, socioeconomic and cultural factors that contribute to a major gender disparity among U.S. men and women undergoing weight loss surgeries. Men undergo the surgeries in far lower numbers than women.

Leapfrog Gives UChicago Medicine 7th Straight 'A' for Hospital Safety

on .

The University of Chicago Medicine was named one of the safest hospitals in the country for the seventh consecutive time by the prestigious and independent Leapfrog Group. UChicago Medicine is one of only 182 U.S. hospitals, out of about 5,000, to receive an A in each survey.

Study Shows Babies Born with Drug Withdrawal Symptoms on the Rise

on .

The number of infants born in the United States with drug withdrawal symptoms, also known as neonatal abstinence syndrome (NAS), nearly doubled in a four-year period. By 2012, one infant was born every 25 minutes in the U.S. with the syndrome, accounting for $1.5 billion in annual health care charges, according to a new Vanderbilt study published in the Journal of Perinatology.

Pancreatic Cancer Risk Linked to Weak Sunlight

on .

Newswise imageWriting in the April 30 online issue of the Journal of Steroid Biochemistry and Molecular Biology, researchers at University of California San Diego School of Medicine report pancreatic cancer rates are highest in countries with the least amount of sunlight. Low sunlight levels were due to a combination of heavy cloud cover and high latitude.

New Light Switches for Neurons Advance Brain Research

on .

Newswise imageLight switches for neurons have made enormous contributions to brain research by giving investigators access to "on switches" for brain cells. But, finding "off switches" has been much more challenging. Addressing the challenge, biochemists in the Center for Membrane Biology at The University of Texas Health Science Center at Houston (UTHealth) discovered a new family of light-activated proteins that work as "off switches."

The Importance of Placebo Effects to Medical Care

on .

The "placebo effect" is often described as events that occur when patients show improvement from treatments that contain no active ingredients. A "Perspectives" article in the July 2 issue of The New England Journal of Medicine proposes that placebo effects be more broadly defined to reflect their role as a valuable component of medical care.

Scientists Identify Protein That Sustains Heart Function Into Old Age

on .

Now research conducted in fruit flies, rats and monkeys by scientists at Johns Hopkins, UC San Diego, and other institutions reveals that levels of a protein called vinculin increase with age to alter the shape and performance of cardiac muscle cells -- a healthy adaptive change that helps sustain heart muscle vitality over many decades.

Penn Author Calls for Better Primary Care for Medicaid Patients to Curb Unnecessary Emergency Room Visits

on .

Although a goal of Medicaid expansion under the Affordable Care Act was to provide Medicaid patients with a source of nonemergency care outside of hospital emergency departments (EDs), researchers suggest that these newly enrolled patients will likely continue to look to EDs for treatment of chronic diseases and other nonemergency issues, despite state attempts to impose fees on ED visits. Health policy researchers suggest in a new Perspective published in the New England Journal of Medicine that patient-centered medical homes may be more effective in reducing the number of Medicare patients seeking nonemergency care in EDs than increasing the cost of the visits.
