Background: Vitamin A and D deficiency is prevalent in pregnant women worldwide. Both vitamins are involved in fetal skeletal development. A positive association between maternal vitamin D levels and offspring bone mineral density (BMD) at adulthood has been observed. The impact of maternal vitamin A status in pregnancy on offspring peak bone mass remains unclear. Method and findings: Forty-one mother-child pairs were recruited from a population-based prospective cohort study in Trondheim, Norway, where pregnant women were followed from gestational week 17. Their term-born infants were followed from birth (1986–88). Regression analyses were performed for vitamin A (retinol), 25-hydroxyvitamin D [25(OH)D] and 1,25-dihydroxyvitamin D [1,25(OH)2D] in maternal serum (gestational weeks 17, 33, 37) and cord blood. Offspring BMD and spine trabecular bone score (TBS), a measure of bone quality, were analyzed by dual x-ray absorptiometry at 26 years. Average levels during pregnancy of retinol, 25(OH)D and 1,25(OH)2D were 1.66 (0.32) μmol/L, 59.0 (20.6) nmol/L, and 251.3 (62.4) pmol/L, respectively. 1,25(OH)2D levels were similar in those with 25(OH)D levels <30 and >75 nmol/L. After adjustment for maternal age, BMI, smoking, and education, and offspring birth weight, maternal serum retinol was positively associated with offspring spine BMD [mean change 30.8 (CI 7.6, 54.0) mg/cm2 per 0.2 μmol/L retinol], and with offspring TBS, although non-significant (p = 0.08). No associations were found between maternal 25(OH)D and 1,25(OH)2D levels and offspring bone parameters. Vitamin levels in cord blood were not associated with offspring BMD or TBS. Conclusions: This is the first study to show an association between maternal vitamin A status and offspring peak bone mass. Our findings may imply increase future risk for osteoporotic fracture in offspring of mothers with suboptimal vitamin A level. No associations were observed between 25(OH)D and 1,25(OH)2D and offspring BMD. [ABSTRACT FROM AUTHOR]

Over the last decades there has been a decline in the recruitment of medical students into academia in all medical fields. Concurrently, medical research has increasingly included other disciplines in multidisciplinary convergence, introducing an unmet recruitment gap and requirement for medical researchers. To counteract the trend and recruit students to academic medicine, a national intercalated Medical Student Research Program (MSRP) was established in Norway in 2002. A preliminary evaluation in 2009 suggested that the MSRP had resulted in recruitment, but could not conclude on a lasting effect beyond graduation in a study that did not include any controls. These results led us to hypothesize that the MSRP could increase the number of PhD degrees and attract medical students towards academic medicine. Adopting a case cohort design, we here report that the intercalated MSRP had a significant impact of the throughput of physician-scientists to PhD, by increasing the rate of PhD completion 10-fold (p<0.001). Moreover, almost twice as many MSRP physicians reported an academic aspiration (49% vs 22%, p<0.001). Results suggested that an MSRP-like approach could efficiently address the unmet recruitment gap and strengthen the medical disciplines in medical research. [ABSTRACT FROM AUTHOR]

Introduction: Perfluoroalkyl substances (PFASs) and organochlorines (OCs) are ubiquitous and persistent in the environment and proposed endocrine disrupting chemicals (EDCs). They can be transferred across the placenta during pregnancy, and studies suggest that the prenatal period may be particularly sensitive for influences on fetal growth and development. Several studies have investigated socio-demographic and pregnancy related factors associated with maternal serum PFAS and OC levels, but few studies have been conducted in time periods with increasing emissions of PFASs and recent emissions of OCs. Methods: Serum from 424 pregnant women participating in the NICHD Scandinavian Successive Small-for-gestational Age (SGA) births study was collected in 1986–1988, and analyses of two PFASs and six OCs were conducted. Associations between EDCs and geographic, time dependent, socio-demographic and pregnancy related variables were evaluated by using multivariable linear regression models. Results: Previous breastfeeding duration, time since last breastfeeding period, sampling date and country of residence were important factors associated with serum levels of PFOS and PFOA. Smoking status and pre-pregnancy BMI were negatively associated with PFOS, and maternal height was borderline negatively associated with PFOS and PFOA. Glomerular filtration rate (GFR) was negatively associated with PFOS in a sub-sample. Maternal serum levels of OCs were positively associated with maternal age, and negatively associated with previous breastfeeding duration and sampling date. Smoking had a consistently negative association with PCB 118 in a dose-dependent manner. Education level, pre-pregnancy BMI and alcohol consumption varied in importance according to the compound under study. Conclusions: Several maternal factors, including potentially modifiable factors, markers of pregnancy physiology and factors also related to perinatal outcomes were associated with EDC levels. Results from this study are relevant to populations with still high PFAS and OC levels, i.e. developing countries. Moreover, we can use this knowledge about associated factors on emerging EDCs with similar properties. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the use of manual vacuum aspiration in postabortion care in Malawi between 2008–2012. Methods: A retrospective cross-sectional study was done at the referral hospital Queen Elisabeth Central Hospital, and the two district hospitals of Chiradzulu and Mangochi. The data were collected simultaneously at the three sites from Feb-March 2013. All records available for women admitted to the gynaecological ward from 2008-2012 were reviewed. Women who had undergone surgical uterine evacuation after incomplete abortion were included and the use of manual vacuum aspiration versus sharp curettage was analysed. Results: Altogether, 5121 women were included. One third (34.2%) of first trimester abortions were treated with manual vacuum aspiration, while all others were treated with sharp curettage. There were significant differences between the hospitals and between years. Overall there was an increase in the use of manual vacuum aspiration from 2008 (19.7%) to 2009 (31.0%), with a rapid decline after 2010 (28.5%) ending at only 4.9% in 2012. Conversely there was an increase in use of sharp curettage in all hospitals from 2010 to 2012. Conclusion: Use of manual vacuum aspiration as part of the postabortion care in Malawi is rather low, and decreased from 2010 to 2012, while the use of sharp curettage became more frequent. This is in contrast with current international guidelines. [ABSTRACT FROM AUTHOR]
