RATIONALE Cardiac fibrosis contributes to pathogenesis of atrial fibrillation (AF), which is the most commonly sustained arrhythmia and a major cause of morbidity and mortality. Although it has been suggested that Ca(2+) signals are involved in fibrosis promotion, the molecular basis of Ca(2+) signaling mechanisms and how Ca(2+) signals contribute to(More)
We previously reported that long-term truck drivers and mechanics in the Teamsters Union had higher lung cancer risks than Teamsters outside the trucking industry. We now summarize results from an industrial hygiene survey of current exposures to diesel exhaust in the trucking industry, and relate these to our prior results pertaining to lung cancer risk.
BACKGROUND It is unclear whether acute conversion of atrial fibrillation (AF) with anti-arrhythmic drugs following cardiac surgery restores and/or maintains sinus rhythm or reduces hospital length of stay (LOS). MATERIAL/METHODS A randomized prospective pilot study was conducted in 2 teaching hospitals from 3/28/98 to 8/2/99 to study the effect of the(More)
BACKGROUND Several studies indicate that truck drivers have an increased risk of lung cancer, but few studies have examined lung cancer risk in heavy equipment operators. Workers in both occupations are exposed to diesel exhaust. AIMS To examine the incidence and mortality from lung cancer among truck drivers and among drivers of heavy vehicles. METHODS(More)
Nasal carriage of Staphylococcus aureus is a sensitive indicator of staphylococcal col-onization and is considered a source of subsequent infection. When the incidence of S. au-reus colonization increased in our neonatal intensive care unit (NICU), resulting in three methicillin-resistant Staphylococcus aureus (MRSA) infections over a three-month period, we(More)
