Turner's syndrome (TS) is one of the most frequent diseases accompanied by growth deficiency. Though developmental disorders have been observed in the fetal period, there has been disagreement as to whether short stature is frequent in newborn girls with Turner's syndrome. Hence we attempted to determine the incidence of 'small ...

Malaria in pregnant women is related to low birth weight (LBW), a factor contributing to infant mortality. Which period of infection during pregnancy leads to the most harmful consequences is unclear. We analyzed data collected in Burkina Faso for 1190 pregnant women. Birth weight was analyzed through multivariate linear and ...

BACKGROUND: Fetal growth is the result of interactions between various factors and can be estimated by ultrasonic measurements. Fetal femur length is a scale for estimating the fetal weight in individual races because fetal growth patterns differ among different races. SUBJECTS AND METHODS: This was a prospective study involving 500 ...

The role of genes in normal birth-weight variation is poorly understood, and it has been suggested that the genetic component of fetal growth is small. Type 2 diabetes genes may influence birth weight through maternal genotype, by increasing maternal glycemia in pregnancy, or through fetal genotype, by altering fetal insulin ...

Good nutrition is essential to help support a successful pregnancy and breast-feeding. Women planning a pregnancy should follow a balanced nutrient-rich diet and consume a daily folic acid supplement up until the end of the first trimester. Many pregnancies, especially amongst teenagers, are unplanned, and educating women of childbearing age ...

Obesity is a major health problem across the world. Recent editorials suggest that obese patients should be denied treatment of any kind aimed to improve ovulation rates and achieve pregnancy until they have reduced their BMI. We propose that this approach is not a resolution of the problem, but indeed ...

A number of studies have been carried out to investigate the crystalline to amorphous conversion of carbamazepine (CBZ) using solid dispersion techniques. In this study we have tried to achieve conversion using a novel technique combining near-supercritical carbon dioxide (n-scCO(2)) and pharmaceutically acceptable polymers (Na CMC and PVP) of varying ...

Converging lines of evidence from epidemiological studies and animal models now indicate that the origins of obesity and related metabolic disorders lie not only in the interaction between genes and traditional adult risk factors, such as unbalanced diet and physical inactivity, but also in the interplay between genes and the ...

The fetal overnutrition hypothesis proposes that greater maternal adiposity results in increased obesity throughout life in the offspring. The authors examined the associations between parental prepregnancy body mass index (BMI; weight (kg)/height (m)(2)), based on height and weight reported by the mother at her first antenatal clinic visit, and offspring ...

The positive deviance approach identifies and promotes existing uncommon healthy behaviours. A positive deviance-informed antenatal project was pilot-tested in Al-Minia Governorate, Upper Egypt, during 2003-2004, after a positive deviance study in 2000 found that successful pregnancies had increased consumption of meat and vegetables, daytime rest, and antenatal care; less second-hand ...

BACKGROUND: The purpose of this study is to compare outcomes of patients who become pregnant within the first year after surgery and those who delayed pregnancy until after 1 year after surgery. METHODS: A retrospective review was performed to identify patients who became pregnant after their gastric-bypass surgery from 2001 ...
