The season of birth is an important risk factor for several diseases. We explored the relationship between birth season and lung cancer. In this population-based retrospective study, we focused on patients with lung cancer who had registered at the Beijing Institute for Cancer Research from 2003 to 2012. In total, 33,025 patients were divided into five subgroups based on their histologic classification, and these five subgroups were compared with the general population (i.e., the permanent resident population of Beijing in 2013)...

BACKGROUND: Large general population surveys show that heavy regular and episodic alcohol consumption are associated with lower intakes of fruits and vegetables, and higher intakes of processed and fried meat. This is of particular concern regarding pregnant women, as both alcohol intake and inadequate maternal nutrition are independently associated with adverse fetal outcomes. The current study aimed to determine associations between maternal dietary patterns and alcohol consumption during pregnancy...

The prevalence of vitamin D deficiency in pregnant white-skinned women (WSW) and their infants has not been investigated at northern latitudes in a developed county. A 2-year observational cohort study was undertaken in the North West of England to determine 25-hydroxyvitamin D (25OHD) levels in WSW and their infants during pregnancy and 4 months postdelivery and to explore factors associated with these levels. Nutritional and lifestyle questionnaires were completed and 25OHD levels measured at 28 weeks and 4 months postdelivery...

BACKGROUND: The health of mothers and their newborns is intricately related. The weight of the infant at birth is a powerful predictor of infant growth and survival, and is considered to be partly dependent on maternal health and nutrition during pregnancy. We conducted a longitudinal study in an urban community within Karachi to determine maternal predictors of newborn birth weight. METHODS: Four hundred pregnant women were enrolled in the study during the period 2011-2013...

BACKGROUND: All countries face significant challenges from complex manifestations of malnutrition, which affects one in three people globally. Systematic reviews provide ready-to-use syntheses of quality-appraised evidence to inform decision-making for actions. To enhance the utility and quality of future Cochrane nutrition evidence, we described the scope and quality of all nutrition systematic reviews in the Cochrane Database of Systematic Reviews (CDSR). METHODS: We screened all active CDSR records (31 July 2015) to identify reviews and protocols using pre-specified eligibility criteria and definitions...

A reliable, easy to assess marker for fertility in agricultural species would be highly desirable and Anti-Müllerian Hormone (AMH) is a promising candidate. This review summarizes recent findings concerning AMH and its role in fertility management, mainly in cattle. It focuses on: 1) alterations in circulating AMH concentrations from birth to puberty and during estrous cycles; 2) correlation of circulating AMH concentrations with ovarian follicle numbers and ovarian reserve; 3) factors that impact circulating AMH concentrations; 4) use of AMH as a predictor of fertility...

The placenta is the main determinant of fetal growth and development in utero. It supplies all the nutrients and oxygen required for fetal growth and secretes hormones that facilitate maternal allocation of nutrients to the fetus. Furthermore, the placenta responds to nutritional and metabolic signals in the mother by altering its structural and functional phenotype which can lead to changes in maternal resource allocation to the fetus. The molecular mechanisms by which the placenta senses and responds to environmental cues are poorly understood...

OBJECTIVE: We aimed to evaluate pregnancy outcome in diet-treated GDM patients according to the 2009 IOM (Institute of Medicine) guidelines concerning gestational weight gain (GWG). DESIGN AND PATIENTS: This was a retrospective cohort study, limited to women with singleton pregnancies and diet-treated GDM. Women with pre-existing diabetes or women with pharmaceutical treatment were excluded. We compared patients with adequate GWG with patients with excess GWG according to the 2009 IOM guidelines...

Theories of the developmental origins of health and disease imply that optimising the growth and development of babies is an essential route to improving the health of populations. A key factor in the growth of babies is the nutritional status of their mothers. Since women from more disadvantaged backgrounds have poorer quality diets and the worst pregnancy outcomes, they need to be a particular focus. The behavioural sciences have made a substantial contribution to the development of interventions to support dietary changes in disadvantaged women...

BACKGROUND: Infertility is a global public health issue, affecting 15% of all couples of reproductive age. Male factors, including decreased semen quality, are responsible for ~25% of these cases. The dietary pattern, the components of the diet and nutrients have been studied as possible determinants of sperm function and/or fertility. OBJECTIVE AND RATIONALE: Previous systematic reviews have been made of the few heterogeneous low-quality randomized clinical trials (RCTs) conducted in small samples of participants and investigating the effect of specific nutrients and nutritional supplements on male infertility...

BACKGROUND: According to recent evidence, up to 40-50% of variance in autism spectrum disorder (ASD) liability might be determined by environmental factors. In the present paper, we conducted a review of systematic reviews and meta-analyses of environmental risk factors for ASD. We assessed each review for quality of evidence and provided a brief overview of putative mechanisms of environmental risk factors for ASD. FINDINGS: Current evidence suggests that several environmental factors including vaccination, maternal smoking, thimerosal exposure, and most likely assisted reproductive technologies are unrelated to risk of ASD...

Certain per- and polyfluoroalkyl substances (PFASs) are suspected developmental toxicants, but data on PFAS concentrations and exposure routes in children are limited. We measured plasma PFASs in children aged 6-10 years from the Boston-area Project Viva prebirth cohort, and used multivariable linear regression to estimate associations with sociodemographic, behavioral, and health-related factors, and maternal PFASs measured during pregnancy. PFAS concentrations in Project Viva children (sampled 2007-2010) were similar to concentrations among youth participants (aged 12-19 years) in the 2007-8 and 2009-10 National Health and Nutrition Examination Survey (NHANES); mean concentrations of most PFASs declined from 2007 to 2010 in Project Viva and NHANES...

Developmental programming is influenced by perinatal nutrition and it has long-lasting impacts on adult metabolism in the offspring. In particular, maternal high fat diet has been associated with increased risk of obesity and metabolic disorders during adulthood in the descendants. These effects may be due to the effects of the high fat diet on the development of the systems that regulate food intake and energy balance in the offspring hypothalamus. The arcuate nucleus (ARC) may be a particularly sensitive region to it as this nucleus contains the POMC and AgRP/NPY neurons that integrate the melanocortin system...

INTRODUCTION: By the time children start school, inequities in learning, development and health outcomes are already evident. Sustained nurse home visiting (SNHV) offers a potential platform for families experiencing adversity, who often have limited access to services. While SNHV programmes have been growing in popularity in Australia and internationally, it is not known whether they can improve children's learning and development when offered via the Australian service system. The right@home trial aims to investigate the effectiveness of an SNHV programme, offered to women from pregnancy to child age 2 years, in improving parent care of and responsivity to the child, and the home learning environment...

Worldwide, the prevalence of childhood obesity has increased, amounting to 42 million overweight or obese children, and there is increasing evidence that the origins are within the first 1,000 days: the period of conception through 2 years. Antecedents of early childhood obesity are multifactorial, and associations of varying strength have been documented for genetic/epigenetic, biologic, dietary, environmental, social, and behavioral influences. Modifiable factors in pregnancy and early infancy associated with childhood obesity include maternal overweight/obesity, maternal smoking, gestational weight gain, infant and young child feeding, caregiver responsive feeding practices, as well as sleep duration, and physical activity...

The physical growth of young children in low- and middle-income countries is reduced compared to international standards. The deviations in growth in both weight and height are greatest in the first 2 years of life and this has serious consequences for child mortality, development, adult stature, and health. The determinants of these patterns of growth faltering include intergenerational factors, such as maternal height, short birth interval, and conditions in pregnancy, including maternal underweight and anemia...

BACKGROUND: Exposures during early life are increasingly being recognised as factors that play an important role in the aetiology of chronic non-communicable diseases (NCDs). The "Developmental Origins of Health and Disease" (DOHaD) hypothesis asserts that adverse early-life exposures - most notably unbalanced nutrition - leads to an increased risk for a range of NCDs and that disease risk is highest when there is a "mismatch" between the early- and later-life environments. Thus, the DOHaD hypothesis would predict highest risk in settings undergoing a rapid nutrition transition...

The "obstetrical dilemma" refers to the tight fit between maternal pelvic dimensions and neonatal size at delivery. Most interest traditionally focused on its generic significance for humans, for example our neonatal altriciality and our complex and lengthy birth process. Across contemporary populations, however, the obstetrical dilemma manifests substantial variability, illustrated by differences in the incidence of cephalo-pelvic disproportion, obstructed labour and cesarean section. Beyond accounting for 12% of maternal mortality worldwide, obstructed labour also imposes a huge burden of maternal morbidity, in particular through debilitating birth injuries...
