patients and methods in this retrospective, cross-sectional study, the medical records of all deceased neonates hospitalized in fatemieh hospital of hamadan, during a 5-year period (2006 – 2011) were extracted. a questionnaire including sex, weight, gestational age, time of birth, delivery mode, maternal disease, and leading cause of death was filled out. the information was then analyzed using...

primary immunodeficiencies (pid) are a group of disorders, characterized by an unusual susceptibility to infections. delay in diagnosis results in increased morbidity and mortality in affected patients. the purpose of this study was to determine the mortality rate of iranian immunodeficient patients referred to children medical center hospital affiliated to tehran university of medical sciences...

thanatology is the academic study of dying, death and grief. it encompasses thoughts, feelings, attitudes, events and the psychological mechanisms of dealing with them. death obsession includes ruminations, repetitive, intrusive thoughts or images about death. death obsession in the nursing profession can occur on a daily basis, and communication with dying patients can be stressful for nurses....

aim : the aim of this study was to provide quantitative estimations of the burden of death in term of years of life lost (yll) due to colorectal cancer (crc) in iran and a temporal trend analysis. background : colorectal cancer is the third most common cause of cancer-related deaths in the world. yll is a tool for quantifying the burden of disease according to mortality rates. the aim of this s...

introduction: one of the most important criteria for health is neonatal mortality. mortality in neonatal period is high, that is about 65% of mortality in infancy occurs below the age of one year. this study was conducted to determine mortality rate in neonates in motazedi hospital of kermanshah during 2002 to 2003. materials & methods: this descriptive study was conducted on the dead neonates ...

A fundamental goal in ecology is to link variation in species function to performance, but functional trait-performance investigations have had mixed success. This indicates that less commonly measured functional traits may more clearly elucidate trait-performance relationships. Despite the potential importance of leaf vein traits, which are expected to be related to resource delivery rates and...

Dangerous, antibiotic resistant bacteria have been observed with increasing frequency over the past several decades. In this review the factors that have been linked to this phenomenon are addressed. Profiles of bacterial species that are deemed to be particularly concerning at the present time are illustrated. Factors including economic impact, intrinsic and acquired drug resistance, morbidity...

Latitudinal differences in life history traits driven by differences in seasonal time constraints have been widely documented. Yet, latitudinal patterns in (age-specific) mortality rates have been poorly studied. Here, we studied latitudinal differences in pre-adult age-specific mortality patterns in the strictly univoltine damselfly Lestes sponsa. We compared individuals from three latitudes r...

If mortality rate is viewed as the outcome of processes of behavior, growth and reproduction, then it should be possible to predict mortality rate as a result of those processes. We provide two examples of how this may be done. In the first, we use the method of linear chains to treat mortality that is the result of multiple physiological processes, some of which may have delays. In the second,...

Size-selective mortality inevitably leads to a decrease in population density and exerts a direct negative effect on targeted size classes. But density and population size structure are also shaped by food-dependent processes, such as individual growth, maturation, and reproduction. Mortality relaxes competition and thereby alters the dynamic interplay among these processes. As shown by the rec...
