Dietary recommendations may be tied to increased greenhouse gas emissions

Dietary recommendations may be tied to increased greenhouse gas emissions

If Americans altered their menus to conform to federal dietary recommendations, emissions of heat-trapping greenhouse gases tied to agricultural production could increase significantly, according to a new study by University of Michigan researchers. Martin Heller and Gregory Keoleian of U-M’s Center for Sustainable Systems looked at the greenhouse gas emissions associated with the production of about 100 foods, as well as the potential effects of shifting Americans to a diet recommended by the U.S Continue reading

Outdoor activities may be linked to exfoliation syndrome in eyes

Outdoor activities may be linked to exfoliation syndrome in eyes

Outdoor activities may increase the odds of developing exfoliation syndrome (XFS) in the eyes, a condition which has been linked to cataracts and glaucoma. XFS is a harmful aging of the eye associated cataracts, elevated intraocular pressure and retinal vein blockage Continue reading

Rare stem cells hold potential for infertility treatments

Rare stem cells in testis that produce a biomarker protein called PAX7 help give rise to new sperm cells — and may hold a key to restoring fertility, research by scientists at UT Southwestern Medical Center suggests. Continue reading

An hour of moderate exercise a day may decrease heart failure risk

Exercising each day can help keep the doctor away. In a new study reported in the American Heart Association journal Circulation: Heart Failure , researchers say more than an hour of moderate or half an hour of vigorous exercise per day may lower your risk of heart failure by 46 percent. Heart failure is a common, disabling disease that accounts for about 2 percent of total healthcare costs in industrialized countries. Continue reading

Researchers examine effectiveness of blocking nerve to help with weight loss

Researchers examine effectiveness of blocking nerve to help with weight loss

Among patients with morbid obesity, blocking the vagus nerve, which plays a role with appetite and metabolism, did not meet pre-specified efficacy objectives compared to a control group, although the intervention did result in greater weight loss, according to a study in the September 3 issue of JAMA . Bariatric surgery can produce significant weight loss and improvement in health but is associated with several potential adverse effects. There is interest in the development of a device that could be as effective or nearly as effective as bariatric surgery but has fewer risks and is less invasive Continue reading

Exit strategy: Is it time to rethink the VA healthcare system?

Exit strategy: Is it time to rethink the VA healthcare system?

As the federal government plans its exit strategy from the war, now may be the time for it to rethink its role in providing health care to veterans, says a Perspective piece in the New England Journal of Medicine. “To simply go on doing more of the same is to fail to recognize the challenge that the Veterans Health Administration’s cost and population structure pose in the longer run,” said William Weeks, from The Dartmouth Institute for Health Policy & Clinical Practice, and David Auerbach, from the RAND Corporation, in the August issue of NEJM . The VA incurs high fixed costs of a brick-and-mortar health care system, the largest salaried workforce in the federal government, and a large administration.To sustain this system, the VA has pursued a strategy of increasing enrollment among veterans — about two-thirds of enrollees use VA services — which has led to calls for expanding and building more facilities.

Expanding age of eligibility for measles vaccination could increase childhood survival in Africa

Expanding the age of eligibility for measles vaccination from 12 to 15 months could have potentially large effects on coverage in Africa, according to a new report published by Princeton University’s Woodrow Wilson School of Public and International Affairs. Continue reading

Newborn screening expansion offers early diagnosis and treatment to infants with SCID

Newborn screening expansion offers early diagnosis and treatment to infants with SCID

Using population-based screening outcomes of approximately 3 million infants, a team of scientists across 14 states, including four researchers at the University of Massachusetts Medical School, have shown that newborn screening for severe combined immunodeficiency (SCID) can be successfully implemented across public health newborn screening programs. Data from 11 newborn screening programs published in the Aug. 20 issue of the Journal of the American Medical Association ( JAMA ) showed the rate of SCID in newborns is higher than previously thought and believed to be 1 in 58,000 Continue reading
