That first cigarette of the morning may be the most dangerous one you have all day. A study of 7,610 smokers, published in the journal Cancer, emphasizes the effect was independent of other smoking habits. Cancer Research UK suggested to BBC News that people who are quick to smoke may inhale more smoke into the lungs and which could nearly double the already high risk of lung cancer. Scientists at the Penn State College of Medicine in the US looked at 4,776 smokers with lung cancer and 2,835...

Children who are obese, asthmatic, anxious or depressed are more likely to experience excessive daytime sleepiness (EDS), according to researchers at Penn State College of Medicine. EDS is the inability to stay awake during daytime hours and often occurs along with other sleep disorders such as sleep apnea -- characterized by pauses in breathing. "Although EDS in children is commonly assumed by physicians and the public to be the result of sleep-disordered breathing or inadequate sleep, our...

It is in your food containers, water bottles, and 90 percent of us have it in our bloodstream. It may also be a prime candidate for causing wheezing in children if pregnant mothers come into contact with it. Experimental research in bisphenol A, (BPA) suggests that prenatal BPA exposure causes asthma in mice. No firm data yet exists for humans but results are not looking good. Adam Spanier, M.D., Ph.D., assistant professor of pediatrics at Penn State College of Medicine, studied 367 children,...

Hershey Medical Center, Hershey, Pa.; Shady Grove Fertility, Rockville, Md.; and Columbia University College of Physicians and Surgeons, New...

New research has shown that people who look forward to smoking a cigarette upon waking up may be at an increased risk of developing lung disease. Dr Joshua E. Muscat, professor of public health sciences at Penn State College of Medicine studied levels of cotinine, a by-product of nicotine when processed by the body among smokers. The study involved more than 250 healthy people who smoked every day. "Since cotinine levels appear to reflect the risk of lung cancer, our results suggest that...

Experts in sleep studies presented evidence that showed poor quality sleep - whether from insomnia, sleep fragmentation, or nightmares - is associated with increased risk of death, Reuters reported. The results came from several presentations last week in Seattle at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies. One study suggested that insomnia might be as hazardous as obstructive sleep apnea, according to researchers at Penn State College of Medicine in...

Researchers at Penn State College of Medicine, working with biochemists, geneticists and clinicians at the University of Bern, Switzerland and in the United Kingdom, have discovered an enzyme that has a key role in inflammatory bowel disease (IBD). The team, co-led by Judith Bond, Ph.D., Distinguished Professor and Chair of Biochemistry and Molecular Biology at Penn State College of Medicine, and Daniel Lottaz, Department of Rheumatology and Clinical Immunology at the University of Bern,...

WASHINGTON (Reuters) -- A common virus that is harmless to people can destroy cancerous cells in the body and might be developed into a new cancer therapy, U.S. researchers said on Tuesday. The virus, called adeno-associated virus type 2, or AAV-2, infects an estimated 80 percent of the population. "Our results suggest that adeno-associated virus type 2, which infects the majority of the population but has no known ill effects, kills multiple types of cancer cells yet has no effect on healthy...
