background: in the past three decades, tehran has experienced warmer summer so we need to determine heat-related mortality to establish appropriate public health activities during hot summers. the aim of the present study was to detect heat waves during the last decades and then determine excess mortality in immediate and lagged times. method: an ecological study based on time-series model was ...

OBJECTIVE To assess the prognostic value of atrioventricular plane displacement in heart failure patients. DESIGN Patients were followed prospectively for one year after atrioventricular plane displacement determination. SETTING Malmö University Hospital, with a primary catchment area of 250,000 inhabitants. PATIENTS 181 patients with a clinical diagnosis of heart failure; age 75.7 (SD 5....

BACKGROUND Mortality displacement (or "harvesting") has been identified as a key issue in the assessment of the temperature-mortality relationship. However, only a few studies have addressed the "harvesting" issue and findings have not been consistent. OBJECTIVES We examined the potential impact of both short- and long-term harvesting effects on heat-related deaths in Brisbane, Australia. M...

BACKGROUND Evaluation of short-term mortality displacement is essential to accurately estimate the impact of short-term air pollution exposure on public health. OBJECTIVES We quantified mortality displacement by estimating single-day lag effects and cumulative effects of air pollutants on mortality using distributed lag models. METHODS We performed a daily time series of nonaccidental and c...
