BACKGROUND Established causes of recurrent pregnancy loss (RPL) include antiphospholipid syndrome, uterine anomalies, parental chromosomal abnormalities, particularly translocations, and abnormal embryonic karyotypes. The number of centers performing preimplantation genetic diagnosis (PGD) for patients with translocations has steadily increased worldwide. The live birth rate with PGD was report...

BACKGROUND The risks of premature birth and perinatal death are increased after in vitro fertilization. These risks are mainly due to the high incidence of multiple births, which relates to the number of embryos transferred. METHODS We performed a randomized, multicenter trial to assess the equivalence of two approaches to in vitro fertilization with respect to the rates of pregnancy that res...

In England and Wales, 53% of live births were born within marriage in 2013, compared to 59% in 2003 and 93% in 1963 [1] . The average age at marriage has increased and more children are born to women older than 30 years. In the UK, there were 2.0 million lone parents with dependent children in 2015. This figure has grown steadily from 1.9 million in 2005. Lone parents with dependent children re...

Birth and death indicators were examined through retrospective surveys conducted in 1985 and 1987 in the Islamic Republic of lran, reviewing 1984 and 1986 events, to obtain infant mortality rate (IMR) and other necessary indicators for health planning and evaluation. Comparison between 1985 and 1987 surveys revealed: 1. No major change in crude death rate ( 6.3 per 1000 in 1987 survey) had...

BACKGROUND Aspirin and low-molecular-weight heparin are prescribed for women with unexplained recurrent miscarriage, with the goal of improving the rate of live births, but limited data from randomized, controlled trials are available to support the use of these drugs. METHODS In this randomized trial, we enrolled 364 women between the ages of 18 and 42 years who had a history of unexplained ...

BACKGROUND The nutrition and epidemiologic transition has been associated with an increasing incidence of preterm birth in developing countries, but data from large observational studies in China have been limited. Our study was to describe the trends and factors associated with the incidence of preterm birth and infant mortality due to prematurity in Hubei Province, China. METHODS We conduct...

Background: Both Heparin and aspirin are used in management of recurrent unexplained miscarriage with the aim to improve the live birth rate and reduce the pregnancy complication. Methods: This is controlled randomized study we enrolled 100 patients with history of recurrent unexplained miscarriage 10 of them have positive anticardiolipin and lupus anticoagulant. Patients were classified into t...

background:   objective: present study was conducted to determine prevalence and risk factors associated with preterm birth in ardabil, iran.   materials and methods: a case control study was conducted between nov 2010 and july 2011 in all three maternal hospitals in ardabil. all the live newborns during the study period were investigated. of 6705 live births during the study period 346 births ...

The present study comprised 381 term babies weighing greater than 2.5 kg and 126 babies weighing less than or equal to 2.5 kg (low birth weight; LBW) at birth. A longitudinal follow up of 334 babies was done for 6 months. There were 273 'breast fed' babies and 234 'artificially fed' babies. Neonatal mortality rate per 1000 live births for term babies was 37.5, LBW had a rate of 31.5 while those...
