BACKGROUND Ambient temperature affects mortality in susceptible populations, but regional differences in this association remain unclear in Japan. We conducted a time-series study to examine the variation in the effects of ambient temperature on daily mortality across Japan. METHODS A total of 731 558 all-age non-accidental deaths in 6 cities during 2002-2007 were analyzed. The association be...

BACKGROUND Climate change has increased the days of unseasonal temperature. Although many studies have examined the association between temperature and mortality, few have examined the timing of exposure where whether this association varies depending on the exposure month even at the same temperature. Therefore, we investigated monthly differences in the effects of temperature on mortality in ...

one of the effects of climate change is the possible increase in both frequency and intensity of extreme weather events. extreme weather and climate events have a major impact on ecosystems and human society due to their severity and the fact that they often occur unexpectedly. in warmer climates and during transition seasons, cold extremes have agricultural impacts that are manifested in the d...

Prevention of exacerbations of chronic obstructive pulmonary disease (COPD) can involve removing the cause or reducing the patient's vulnerability to the cause. This article addresses the following issues: What is the problem during an exacerbation, what are the causes of an exacerbation, what can prevent exacerbations, and who are we? The difference between a patient with COPD during an exacer...

In China, the health impact of cold weather has received little attention, which limits our understanding of the health impacts of climate change. We collected daily mortality and meteorological data in 66 communities across China from 2006 to 2011. Within each community, we estimated the effect of cold spell exposure on mortality using a Distributed Lag Nonlinear Model (DLNM). We also examined...

This work has as objective to study the influence of mixing hour in the concrete properties such as workability and compressive strength in hot and cold weather conditions from an industrially applied point of view. The foremost studied variable was the concrete mixing hour, having used five mixing hours for every weather conditions. For each mixing hour, were carried out three concrete batches...

Effects of local weather on individuals and populations are key drivers of wildlife responses to climatic changes. However, studies often do not last long enough to identify weather conditions that influence demographic processes, or to capture rare but extreme weather events at appropriate scales. In Iceland, farmers collect nest down of wild common eider Somateria mollissima and many farmers ...

One of the most visible and widely felt impacts of climate warming is the change (mostly loss) of low-elevation snow cover in the midlatitudes. Snow cover that accumulates at temperatures close to the ice-water phase transition is at greater risk to climate warming than cold climate snowpacks because it affects both precipitation phase and ablation rates. This study maps areas in the Pacific No...

OBJECTIVES To explore the association between weather conditions and hospital admissions for pneumonia in Shanghai. DESIGN A time-series analysis was performed for a period of 4 years (January 2008-December 2011). A generalised additive model was used to calculate the relative risks. SETTING Shanghai, China. PARTICIPANTS All daily hospital admissions for pneumonia were obtained from the S...

Background. In Uganda Malaria continues to be a major public health problem accounting for about 30-50% of all outpatient consultations and 35% of hospital admissions and a leading cause of mortality and morbidity. Pregnant women and their unborn children are vulnerable to malaria. Methods. A cross-sectional survey was conducted in 20 postconflict IDP camps of Gulu district selected randomly as...
