Scandalous bodies and our relationship with food

Attitudes toward over-indulgence, obesity and body shape were being hotly debated and used for political purposes as early as the 19^th century, a new book claims. ‘Pathological Bodies’, by Dr Corinna Wagner from the University of Exeter, shows that body consciousness is not just a modern-day phenomenon.

Instead, medical warning about excessive eating and drinking, and public attitudes about self-control and discipline emerged more than 250 years ago, when the perceived decadence of the Georgian period gave way to the more moderate and austere approach adopted by the Victorians. (more…)

A new drug, called pritelivir, may offer a new treatment option for patients with genital herpes, a new industry-sponsored – study led by University of Washington researchers has found.

The study appears in this week’s issue of the New England Journal of Medicine. The lead author is Anna Wald, M.D., professor of medicine, epidemiology, and laboratory medicine, and medical director at the Virology Research Clinic at the University of Washington. Other UW coauthors include Dr. Amalia Magaret, Dr. Christine Johnston, Dr. Lawrence Corey, Dr. Meei-Li Huang and Stacy Selke. (more…)

Study identifies essential molecule for transport of protein from neuron cell body to axon

COLUMBUS, Ohio – Scientists have solved a longstanding mystery of the central nervous system, showing how a key protein gets to the right spot to launch electrical impulses that enable communication of nerve signals to and from the brain.

Nerve impulses are critical because they are required for neurons to send information about senses, movement, thinking and feeling to other cell types in the neural circuitry. And an impulse is not fired up just once; it is initiated and then must be repeatedly transmitted along axons – long, slender extensions of nerve cell bodies – to keep the nervous system’s messages stable during their rapid travel.

Trial to test using ultrasound to move kidney stones

Almost one in 10 people will someday experience a kidney stone, which creates what is described as the most intense pain imaginable. This increasingly common condition leads to hundreds of thousands of surgeries in the United States each year.

A new device developed at the University of Washington would let doctors use ultrasound to move kidney stones inside the body and help them pass by natural means. (more…)

Black patients fare worst; Asians, Hispanics survive longest with disease

UCLA researchers have found that minority patients and those of lower socioeconomic status are far more likely to have advanced thyroid cancer when they are diagnosed with the disease than white patients and those in higher economic brackets.

In one of the most comprehensive studies of its kind, the UCLA team looked at nearly 26,000 patients with well-differentiated thyroid cancer and analyzed the impact of race and socioeconomic factors on the stage of presentation, as well as patient survival rates. (more…)

Racism May Accelerate Aging in African American Men

UMD-led study is first to link racism-related factors and cellular age

COLLEGE PARK, Md. – A new University of Maryland-led study reveals that racism may impact aging at the cellular level. Researchers found signs of accelerated aging in African American men who reported high levels of racial discrimination and who had internalized anti-Black attitudes. Findings from the study, which is the first to link racism-related factors and biological aging, are published in the American Journal of Preventive Medicine.

Racial disparities in health are well-documented, with African Americans having shorter life expectancy, and a greater likelihood of suffering from aging-related illnesses at younger ages compared to whites. Accelerated aging at the biological level may be one mechanism linking racism and disease risk. (more…)

A Yale study estimates that 8 million lives have been saved in the United States as a result of anti-smoking measures that began 50 years ago this month with the groundbreaking report from the Surgeon General outlining the deadly consequences of tobacco use. The Yale School of Public Health-led analysis is published in the Journal of the American Medical Association.

The study used mathematical models to calculate the long-term effect of the seminal report, and subsequent anti-smoking measures, over the past half-century. These cumulative efforts have significantly reshaped public attitudes and behaviors concerning cigarettes and other forms of tobacco, note the researchers. (more…)
