H1N1 flu :: Pandemic swine flu – H1N1 Influenza

Novel H1N1 (referred to as “swine flu” early on) is a new influenza virus causing illness in people. This new virus was first detected in people in the United States in April 2009. Other countries, including Mexico and Canada, have reported people sick with this new virus. This virus is spreading from person-to-person, probably in much the same way that regular seasonal influenza viruses spread.

Heart :: Aging heart changes shape, shrinks and loses pumping function too

Researchers at Johns Hopkins have evidence to explain why the supposedly natural act of aging is by itself a very potent risk factor for life-threatening heart failure.

HIV :: HIV-TB spreads in Africa, undermines control of world’s 2 deadliest infectious diseases

The largely unnoticed collision of the global epidemics of HIV and tuberculosis (TB) has exploded to create a deadly co-epidemic that is rapidly spreading in sub-Saharan Africa. However, health systems cannot adequately diagnose, treat, or contain the co-epidemic due to unanswered scientific and medical questions, according to a report issued today by The Forum for Collaborative HIV Research and amplified by experts from leading global health organizations.

Health Insurance :: Private/public insurance mix is most practical way to achieve universal coverage

Health insurance reform plans that build on a mix of private and public health insurance, where costs are shared among government, employers, and enrollees would have great potential to move the system to high performance and would be the most practical to implement according to a new report released today by The Commonwealth Fund Commission on a High Performance Health System. Commissioners are a diverse group of leading health policy experts from government, private industry, health care delivery organizations, academia, and professional associations.

Colorectal Cancer :: Colorectal cancer screening remains essential for elderly Americans

As people get older, their risk of developing polyps and colorectal cancer increases. Currently, there is no clear evidence or established guideline for the upper age limit for colorectal cancer screening by colonoscopy. Two new studies presented at the American College of Gastroenterology’s 72nd Annual Scientific Meeting suggest continued colorectal cancer screening among healthy elderly Americans.

Obesity :: Genes may make some people more motivated to eat, perhaps overeat

Science has found one likely contributor to the way that some folks eat to live and others live to eat. Researchers at the University at Buffalo, The State University of New York, have found that people with genetically lower dopamine, a neurotransmitter that helps make behaviors and substances more rewarding, find food to be more reinforcing than people without that genotype. In short, they are more motivated to eat and they eat more.

Exercise :: Moderate activity is more beneficial than vigorous exercise

British adults now believe that moderate activity is more beneficial than vigorous exercise, according to new research by the University of Exeter and Brunel University. Although most large studies show that the greatest health benefits are derived from regular participation in vigorous activities, such as jogging and competitive sports, 56% of men and 71% of women now believe moderate activities, like walking, are most beneficial.
