Research from Weill Medical College of Cornell University and other institutions provides new evidence that the sex steroid hormone progesterone is also a vasoactive hormone that directly affects blood vessels. This finding sheds light on both the drop in blood pressure that usually accompanies pregnancy (when progesterone levels are high) and the rise in blood pressure that often occurs in women after menopause (when the production of progesterone falls off). It may also focus and sharpen the debate on the value of female hormones in long-term cardiovascular protection.

A large, randomized study involving more than 3,600 New York City schoolchildren (most of them black or Hispanic) has found that an intervention program that teaches drug refusal skills, antidrug norms, and social and self-management skills can reduce tobacco, alcohol, and drug use among such youth for as long as two years.

A new study by the physicians of the Early Lung Cancer Action Project reports that with annual computed tomography screenings false positives were uncommon, and 83% of the lung cancers discovered were in the earliest, most curable stage.

Through a student-led volunteer program called REMEDY, New York Weill Cornell Medical Center has begun gathering many of its surplus supplies, such as surgical drapes, gloves, and instruments, and shipping them to needy institutions in places like Africa and Russia.

As the obesity epidemic grows in the United States, the medical community is faced with the significant challenge of properly treating patients before complications such as heart disease arise. But, as obesity expert Louis Aronne, MD, explained, ongoing research into the endocannabinoid system shows promise in combating obesity and the associated cardiometabolic risks.

Cardiovascular disease (CVD), or disease of the heart and blood vessels, continues to be a leading killer of men and women in the United States, accounting for close to 30 percent of all deaths annually. According to a leading researcher, CVD will remain a major cause of death unless Americans make a concerted effort to manage all of their risks.

Benjamin H. Lewis, MD, of the Columbia Presbyterian Center of New York-Presbyterian Hospital, has become the first cardiologist in New York State to receive accreditation from the Intersocietal Commission of Accreditation of Echocardiography Laboratories (ICAEL) for stress echocardiography, a noninvasive method of diagnosing cardiac disease.

Researchers at the Weill Medical College of Cornell University reported that mice which were administered a gene-based therapeutic agent to induce hair growth showed marked acceleration of the onset of new hair growth two weeks after treatment.
