Asthma :: Farm kids have lower risk of asthma, study
Farm children appear to have a lower risk of asthma than their urban counterparts or even those living in a nonagricultural rural environment, according to a University of Alberta study.
Schizophrenia :: How schizophrenia develops, major clues discovered
Schizophrenia may occur, in part, because of a problem in an intermittent on/off switch for a gene involved in making a key chemical messenger in the brain, scientists have found in a study of human brain tissue. The researchers found that the gene is turned on at increasingly high rates during normal development of the prefrontal cortex, the part of the brain involved in higher functions like thinking and decision-making — but that this normal increase may not occur in people with schizophrenia.
Cancer :: Cancer death rate decline doubling in US, says CDC
A new report from the nation’s leading cancer organizations shows cancer death rates decreased on average 2.1 percent per year from 2002 through 2004, nearly twice the annual decrease of 1.1 percent per year from 1993 through 2002.
Cancer :: CD8+ T cells LAG behind
New data generated using mice by Charles Drake and colleagues at Johns Hopkins University School of Medicine, Baltimore, have identified a role for the protein LAG-3 in limiting the response of immune cells known as CD8+ T cells to both host and tumor proteins.
Immunity :: The ins and outs of how neutrophils combat microbes
Immune cells known as neutrophils produce reactive oxygen intermediates (ROIs) to combat infection with microbes that can cause diseases such as pneumonia. New insight into the molecular pathway regulating neutrophil production of ROIs in mice has been provided by Wojciech Swat and colleagues at Washington University School of Medicine, St. Louis.
Heart :: Role of mast cells in development of abdominal aortic aneurysm
Abdominal aortic aneurysm (AAA) is a common disease of the main artery (the aorta) in the elderly. It is characterized by a dilated aorta and if allowed to develop unchecked it can rupture, an event with a high rate of mortality.
Tonsillectomy :: Tonsillectomy associated with improved sleep and behavior in children with breathing disorders
Children diagnosed with sleep-disordered breathing appear to sleep better and have improved behavior following removal of their tonsils and adenoids, according to a report in the October issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.
Health :: 2 studies highlight the risks and significant health-care costs of NSAIDs injury
New studies highlight the risks and significant health care costs of GI injury and bleeding from the use of NSAIDs. According to a survey conducted at Eastern Virginia Medical School, 22 percent of respondents did not think NSAIDs were important to mention to their doctor, revealing a common misperception about these over-the-counter remedies.
Colorectal Cancer :: Racial and ethnic differences in colorectal cancer emphasize importance of screening
New research presented at the 72nd Annual Scientific Meeting of the American College of Gastroenterology emphasizes the importance of colorectal cancer (CRC) screening among racial and ethnic minorities, who have a higher incidence of colorectal cancer compared to Caucasians. Two studies found more African-Americans had advanced polyps on the right side of the colon than Caucasians, while results from colonoscopy screenings of Latin Americans revealed similarly high risk findings to African-Americans.
