What Everest Teaches About Disease

A team of Mayo Clinic scientists recently accompanied climbers to Mount Everest to study the effects of high altitude. And researchers from the University of Colorado, Denver, are planning a high-altitude research trip to Bolivia with 24 study participants. For four weeks starting April 20, Mayo Clinic researchers were in Nepal taking physiological measurements of 10 climbers' hearts and lungs, as well as conducting sleep studies and cognitive performance tests on them. 

By studying the climbers, six of whom reached the summit, the researchers hope to gain insight into heart failure, lung disease and sleep apnea—all conditions related to a low-oxygen, or hypoxic, state. The longer people spend at extreme high altitude, the longer their bodies lack the needed amount of oxygen and the lower their energy—stresses similar to those caused by the diseases.

The proportion of oxygen in the air—21%—is constant whether at sea level or on the highest peak, but at lower altitudes there is more air pressure to force oxygen into tissue. At higher altitudes, where atmospheric pressure is lower, oxygen enters the body less readily, leading to the hypoxic state.
 
The research also might lead to new ways of controlling the body's response to low oxygen in other contexts, such as one day helping limit growth of certain solid-tumor cancers, which need oxygen and blood vessels to grow, Dr. Roach says.

Altitude research already benefits patients with medical conditions and vice versa. Asthma inhalers like albuterol, which work by stimulating beta-receptor cells in the lungs, were first used to treat high-altitude climbers. Conversely, several heart-failure medicines are now in use to treat altitude sickness or help with acclimatization, researchers say.

F.D.A. Staff Raises Concerns About Arthritis Drug

Federal regulators said Monday that an experimental pill being developed by Pfizer to treat rheumatoid arthritis raised “serious safety concerns” and was linked to a higher risk for lymphoma, a form of cancer, and serious infections. Pfizer has identified the drug, known as tofacitinib, as one of the most promising and lucrative prospects in its drug pipeline.

The briefing documents, prepared by F.D.A. staff members and released Monday ahead of the meeting, also found that although tofacitinib did ease the symptoms of rheumatoid arthritis and the physical functioning of those who have it, the studies didn’t definitively show that the drug stopped the disease from progressing.

Lower Your Risk of Diabetes, Eat Breakfast

In a study published in the current issue of The American Journal of Clinical Nutrition, researchers followed 29,000 men for 16 years, tracking their diets, exercise, disease rates and other markers of health. About 2,000 of the men developed Type 2 diabetes over the course of the study. 

Those who regularly skipped breakfast had a 21 percent higher risk of developing diabetes than those who did not. The heightened risk remained even after the researchers accounted for body mass index and the quality of the subjects’ breakfasts.Other studies have also found a link between skipping breakfast and greater risk of Type 2 diabetes. While it is not clear why the relationship exists, some scientists suspect that a morning meal helps stabilize blood sugar through the day.
