It can also contribute to the design more effective prenatal care. This study was performed aiming to evaluate the maternal risk factors associated with mortality in preterm infants in Mashhad Ghaem Hospital, Iran, during 2009-2014. Methods: Th...
Managers are often concerned about oak mortality in maturing mixed-oak forests, but they often lack explicit information about mortality risk for oaks that differ in species, size, crown class, competitive status, and growth rate. In eastern North America, tree species in the red oak group (Quercus Section Lobatae) are typically shorter lived than those in the white oak group (Section Quercus),...
Background: Maternal mortality is one of the most important indicators of women health standard in developing countries. This study aimed to determine the prevalence of risk factors and etiology of maternal mortality in a geographic region of Iran. Methods: This descriptive- analytic cross sectional study included all pregnant women who died during pregnancy and six weeks after delivery due to...
Background and Objective: Understanding the factors contributing to the mortality of COVID-19 patients can provide comprehensive information for preventive decisions and public health, and will help in better management of the epidemic. In this regard, the present study was conducted with the aim of identifying and introducing risk factors affecting the mortality of COVID-19 patients by modifia...
Background and purpose: Coronary artery bypass surgery (CABG) is an effective and important treatment for patients with coronary artery disease. In recent years there has been increasing interest in prediction of mortality and patient's outcome after cardiac surgery. Several models have been designed to identify related risk factors. This study aimed at evaluating EuroSCORE model in CABG patien...
Background: The coronavirus disease 2019 (COVID-19 the seventh human coronavirus) was discovered in Wuhan, Hubei province of China, in January 2020. COVID-19 virus caused six million deads in the world to date and cussed infection of more than seven million of cases in Iran(1). This infectious disease caused by the SARS-CoV-2 virus. This virus was contagious and fast-spread. Despite the aquaran...
Background and Aim: Mortality from cardiovascular and other chronic diseases has increased in Iran. Our aim was to estimate the effects of smoking and high systolic blood pressure (SBP), fasting plasma glucose (FPG), total cholesterol (TC), and body mass index (BMI) on mortality and life expectancy, nationally and sub-nationally using representative data and comparable methods. Materials and M...
مقدمه: سندرم دیسترس حاد تنفسی (acute respiratory distress syndrome یا ards) با وجود درمان شدید و تهویه ی مکانیکی طولانی مدت با مرگ و میر بالا و افت شدید کیفیت زندگی نجات یافتگان همراه است. یافته های مطالعات انجام شده در زمینه ی پیش آگهی این سندرم متناقض بود. از این رو، مطالعه ی حاضر جهت تعیین عوامل مؤثر بر سندرم دیسترس تنفسی حاد کودکان طراحی گردید. روش ها: در این مطالعه ی مقطعی تمام پرونده های ...
Introduction: Ischemic heart disease is the most common cause of mortality in developed countries. CABG (Coronary Artery Bypass Graft) is one of the therapeutic methods in ischemic heart disease. Methods and Materials: Considering the increased incidence of coronary artery disease in Iran, and with increased rate of CABG, we performed a cross sectioned study (1996-1999). In 635 patients 467 mal...
Understanding how and why insect numbers fluctuate through time and space has been a central theme in ecological research for more than a century. Life tables have been used to understand temporal and spatial patterns in insect numbers. In this study, we estimated cause-of-death probabilities for phytophagous insects using multiple decrement life tables and the irreplaceable mortality analytic ...
