Melanoma risk found to have genetic determinant

Melanoma risk found to have genetic determinant

A leading Dartmouth researcher, working with The Melanoma Genetics Consortium, GenoMEL, an international research consortium, co-authored a paper published in the Journal of the National Cancer Institute that proves longer telomeres increase the risk of melanoma. “For the first time, we have established that the genes controlling the length of these telomeres play a part in the risk of developing melanoma,” said lead author of the study Mark Iles, PhD, School of Medicine at the University of Leeds (UK). Telomeres are a part of the genome that function like the plastic caps of your shoelaces, which prevent the laces from fraying Continue reading

Americans rate losing eyesight as having greatest impact on their lives

Americans rate losing eyesight as having greatest impact on their lives

Many Americans across racial and ethnic groups describe losing eyesight as potentially having the greatest impact on their day-to-day life, more so than other conditions including: loss of limb, memory, hearing and speech (57% of African-Americans, 49% of non-Hispanic whites, 43% of Asians and 38% of Hispanics). When asked which disease or ailment is the worst that could happen to them, blindness ranked first among African-Americans followed by AIDS/HIV. Continue reading

Professional recommendations against routine prostate cancer screening have little effect

Professional recommendations against routine prostate cancer screening have little effect

The effect of guidelines recommending that elderly men should not be routinely screened for prostate cancer “has been minimal at best,” according to a new study led by researchers at Henry Ford Hospital. The study, published as a research letter online in JAMA Internal Medicine , focused on the use of PSA — prostate-specific antigen — to test for prostate cancer. Continue reading

Few physicians are recommending HPV vaccination for boys, study finds

Few physicians are recommending HPV vaccination for boys, study finds

Research from Moffitt Cancer Center shows family physicians and pediatricians are not always recommending vaccination against human papillomavirus (HPV) for young male patients. Approximately 6 million people are newly infected with HPV each year, a virus that can lead to the development of cancer Continue reading

U.S. health system not properly designed to meet needs of patients nearing end of life, say experts

U.S. health system not properly designed to meet needs of patients nearing end of life, say experts

The U.S. health care system is not properly designed to meet the needs of patients nearing the end of life and those of their families, and major changes to the system are necessary, says a new report from the Institute of Medicine. The 21-member committee that wrote the report envisioned an approach to end-of-life care that integrates traditional medical care and social services and that is high-quality, affordable, and sustainable Continue reading

Certain gut bacteria may induce metabolic changes following exposure to artificial sweeteners

Certain gut bacteria may induce metabolic changes following exposure to artificial sweeteners

Artificial sweeteners — promoted as aids to weight loss and diabetes prevention — could actually hasten the development of glucose intolerance and metabolic disease, and they do so in a surprising way: by changing the composition and function of the gut microbiota — the substantial population of bacteria residing in our intestines. These findings, the results of experiments in mice and humans, were published September 17 in Nature . Continue reading

First blood test to diagnose depression in adults

First blood test to diagnose depression in adults

The first blood test to diagnose major depression in adults has been developed by Northwestern Medicine® scientists, a breakthrough approach that provides the first objective, scientific diagnosis for depression. The test identifies depression by measuring the levels of nine RNA blood markers. RNA molecules are the messengers that interpret the DNA genetic code and carry out its instructions.
