BACKGROUND Psychological variables, such as anxiety and depression, may have a negative impact on IVF outcomes, but the evidence remains inconclusive. Previous studies have usually measured a single psychological parameter with clinical pregnancy as the outcome. The objective of the current study was to determine whether pretreatment or procedural psychological variables in women undergoing a f...

OBJECTIVE Estimate the number of live births and, therefore, underreporting of live births. METHODS The databases of the Live Birth Information System and the Civil Registry of the Brazilian Institute of Geography and Statistics, from the second and third trimesters of 2006 in Sergipe state (Northeastern Brazil) were paired by deterministic linkage based on the number of the Live Birth Declar...

BACKGROUND Maternity histories provide a means of estimating fertility and mortality from surveys. METHODS The present analysis compares two types of maternity histories-birth histories and pregnancy histories-in three respects: (1) completeness of live birth and infant death reporting; (2) accuracy of the time placement of live births and infant deaths; and (3) the degree to which reported v...

The aim of this study was to investigate the relation between erythrocyte parameters of piglets and their mortality during parturition. Erythrocyte count, haematocrit volume, blood haemoglobin concentration, mean cell volume (MCV), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC) were determined in 80 live-born and 109 stillborn piglets. In both live-born and stillborn...

BACKGROUND Outcomes of in vitro fertilization (IVF) treatment are traditionally reported as pregnancies per IVF cycle. However, a couple's primary concern is the chance of a live birth over an entire treatment course. METHODS We estimated cumulative live-birth rates among patients undergoing their first fresh-embryo, nondonor IVF cycle between 2000 and 2005 at one large center. Couples were f...

1035 married women workers in three modern textile mills in Anhui, China were surveyed to investigate the association of rotating shiftwork with low birth weight and preterm birth in 1992. Information on reproductive health, occupational exposure history, and other covariates including age at pregnancy, time and duration of leave from job since pregnancy, and mill location was obtained by train...

background and purpose: prematurity birth occurs when a newborn is born before the thirty seventh week of pregnancy. preterm birth is the most expensive and the most common health problem. so, the aim of this study was to do epidemiological survey of prematurity in gonbad-e kavous in 2010. materials and methods: this sectional- descriptive study was carried out on 172 premature babies with cens...

BACKGROUND Although elective single embryo transfer (eSET) minimizes the multiple birth rate after in vitro fertilization (IVF)/intra cytoplasmic sperm injection (ICSI), there remain concerns in many countries that it is less effective and more expensive than conventional double embryo transfer (DET). METHODS We compared the clinical outcome achieved in the years 1995-1999, in which eSET was ...
