abstractbackground: the survival rate of preterm and low-birth-weight (lbw) infants depends on various factors such as birth weight, gestational age, and quality of care. the present study aimed at evaluating the survival rate of preterm and lbw infants, predictive factors, and the risk of mortality in three training hospitals of mashhad and tabriz cities.methods: this prospective, cohort study...

KEY FINDINGS Following a long period of fairly steady increase, the U.S. preterm birth rate declined for the second straight year in 2008 to 12.3 percent, from 12.8 percent in 2006. This marks the first 2-year decline in the preterm birth rate in nearly three decades. Preterm birth rates declined from 2006 to 2008 for mothers of all age groups under age 40, for the three largest race and Hispan...

Background: While a number of countries have reported rising preterm birth rates over the past two decades, none has examined the effects of socioeconomic status on preterm birth at a national level. Aim: To document the changing incidence of preterm birth in New Zealand over the past 20 years and to determine whether particular socioeconomic or ethnic subsections of the population have contrib...

STUDY OBJECTIVE To study whether hospitals of different levels are equally safe places to give birth in a regionalised system of care. DESIGN This was a population based, cross sectional survey comparing birth outcomes in nationwide catchment areas of different levels of hospital care. All women and low risk women were examined separately. SETTING AND SUBJECTS The study population comprised...

There is some evidence that perinatal factors, specifically birth weight (BW), may be related to the onset of prostate cancer (PRCA). This case-control study, nested within the Malmö Diet and Cancer Cohort Study, used archived birth record data from 308 incident PRCA cases diagnosed between 1991 and 2005, and 637 age-matched controls among 4781 men born (1923-1945) in Malmö and Lund, Sweden. We...

Accurate estimates of mortality at advanced ages are essential to improving forecasts of mortality and the population size of the oldest old age group. However, estimation of hazard rates at extremely old ages poses serious challenges to researchers: (1) The observed mortality deceleration may be at least partially an artifact of mixing different birth cohorts with different mortality (heteroge...
