PHILADELPHIA – A study published in Cancer Research, a journal of the American Association for Cancer Research, suggests a possible role for nicotine in breast tumor development and metastases.
The study, conducted by researchers at the Beth Israel Deaconess Medical Center, is among the first to explore the effects of nicotine on mammary cells.
Westchester, Ill. –A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that unrelated to obesity, people with severe SDBs consume a more unhealthy diet, which may be a factor contributing to greater cardiovascular morbidity and mortality. These findings were most evident among women.
Stuart Quan, MD, division of sleep medicine at Harvard Medical School, said, "We found that persons who had severe obstructive sleep apnea ate a diet that was unhealthy with increased intake of cholesterol, fat and saturated fatty acids."
Westchester, Ill. –A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that respiratory sinus arrhythmia (RSA) is a significant predictor of insomnia in women with breast cancer and confirmed that longer nocturnal wake episodes were associated with a flatter diurnal cortisol slope.
Researchers have reported positive results from a safety and efficacy study pertaining to tribendimidine, a broad-based treatment for intestinal worm infections. The group's results demonstrate the success of the new drug from China versus that of the standard albendazole for the treatment of hookworm, large roundworm, whipworm, and, for the first time, threadworm and tapeworm.
Researchers have found that the fight against Buruli ulcer, a tropical skin disease, has hit a bump in Central Cameroon. Even as organizations provide free-of charge hospitalization care, patients' economic and social costs are preventing and delaying the treatment. Their study results are published October 15 in the open-access journal PLoS Neglected Tropical Diseases.
The discovery of the earliest known cases of human tuberculosis (TB) in bones found submerged off the coast of Israel shows that the disease is 3000 years older than previously thought. Direct examination of this ancient DNA confirms the latest theory that bovine TB evolved later than human TB.
The new research, led by scientists from UCL (University College London) and Tel-Aviv University and published today in PLoS One, sheds light on how the TB bacterium has evolved over the millennia and increases our understanding of how it may change in the future.
The further north you go, the more likely you are to have faecal bacteria on your hands, especially if you are a man, according to a preliminary study conducted by the London School of Hygiene & Tropical Medicine.
(SACRAMENTO, Calif.) — A new study sheds light on the lives of teenage boys who abuse their girlfriends. In their own words, the young men often describe facing challenges such as growing up with troubled family lives, having little or no support when they began to fail at school, and witnessing violence in their own homes and communities. The study advocates broadening the view of abusive behaviors within dating relationships to explore the myriad environments — school, home and community — that affect boys' lives and actions.
Two independent papers in the October 15th issue of G&D detail the discovery of a previously unidentified fourth component of the Bloom's syndrome complex.
Bloom's syndrome is an inherited cancer predisposition disease, resulting from mutations in a gene on the long arm of chromosome number 15. The BLM gene encodes for one part of a multi-enzyme Bloom's syndrome complex (called BTB) that facilitates DNA repair, and helps ensure the integrity of the genome.
WASHINGTON – OCTOBER 14, 2008 – Newly reported data presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF) from the SYNTAX clinical trial (SYNergy Between PCI With TAXUS and Cardiac Surgery) reveal similar safety and efficacy outcomes when the use of a drug-eluting stent is compared to heart bypass surgery in patients with left main disease.
New evidence discovered by researchers at The University of Texas School of Public Health Brownsville Regional Campus shows that patients with Type 2 diabetes may be at increased risk of contracting tuberculosis because of a compromised immune system, resulting in life-threatening lung infections that are more difficult to treat.
An herbicide that is effective at killing broadleaf weeds in corn, but also annihilated most of the grapes in Illinois and other Midwestern states, may finally have a worthy contender. Researchers at the University of Illinois have developed a new grape called Improved Chancellor which is resistant to the popular herbicide 2, 4-D.
A majority of Medicare patients with stable coronary artery disease who underwent an elective percutaneous coronary intervention (PCI; procedure such as angioplasty or stenting to open narrowed coronary arteries) did not have a recommended stress test performed to confirm the necessity of the procedure, according to a study in the October 15 issue of JAMA.
High-dose vitamin B supplementation for patients with mild to moderate Alzheimer disease did not slow the rate of cognitive decline, according to a study in the October 15 issue of JAMA.
Reducing how often a patient receives amiodarone, a medication used for suppressing atrial fibrillation (irregular heart beat) but which causes side effects, did not decrease the overall amount of amiodarone-related and heart disease related side effects, but did increase the rate of atrial fibrillation recurrence and the risk of death from all causes and cardiovascular hospitalizations, according to a study in the October 15 issue of JAMA.
