BACKGROUND: Prematurity is known to be associated with high rates of endocrine and metabolic complications in the offspring. Early term (37 0/7-38 6/7 weeks' gestation) born offspring were also shown to exhibit long term morbidity resembling that of late preterm, in several health categories. OBJECTIVE: We aimed to determine whether early term delivery impacts on the long-term endocrine and metabolic health of the offspring. STUDY DESIGN: A population-based cohort analysis was performed, including all term singleton deliveries occurring during 1991-2013 at a single regional tertiary medical center...

REVIEW
Wayne R Cohen
The assessment of uterine contractions is important in clinical decision-making, but the precise role for appraising contractions remains controversial. Four clinical approaches to assessing contractions are available: manual palpation; intrauterine pressure determination; external tocodynamometry; and electrohysterography. Palpation is inexpensive and harmless but requires the constant bedside presence of a trained observer. Intrauterine pressure measurement is considered the most sensitive and specific technique, and has become the standard by which other methods are judged; however, its quantitative measurements are not always precise or reproducible...

Despite public concerns about the negative implications of the increased labor force participation of mothers for child development, decades of research have revealed few risks and some benefits. One potential risk-a consistently observed association between maternal employment and childhood obesity-offers a window into how some dimensions of family health may be undermined by work in an economic and policy context that is not family friendly. The purpose of this article is to identify ways that a developmental perspective can enrich the literature on how children's weight may be related to the work experiences of both mothers and fathers across diverse populations, a literature that heretofore has been dominated by economic and demographic perspectives, focused almost solely on women, and largely ignored racial/ethnic variation...

Tetsuya Kawakita, Helain J Landy
Cesarean delivery (CD) is one of the most common procedures performed in the United States, accounting for 32% of all deliveries. Postpartum surgical site infection (SSI), wound infection and endometritis is a major cause of prolonged hospital stay and poses a burden to the health care system. SSIs complicate a significant number of patients who undergo CD - 2-7% will experience sound infections and 2-16% will develop endometritis. Many risk factors for SSI have been described. These include maternal factors (such as tobacco use; limited prenatal care; obesity; corticosteroid use; nulliparity; twin gestations; and previous CD), intrapartum and operative factors (such as chorioamnionitis; premature rupture of membranes; prolonged rupture of membranes; prolonged labor, particularly prolonged second stage; large incision length; subcutaneous tissue thickness > 3 cm; subcutaneous hematoma; lack of antibiotic prophylaxis; emergency delivery; and excessive blood loss), and obstetrical care on the teaching service of an academic institution...

BACKGROUND: The prevalence of obesity and other chronic diseases is increasing in India and around the world. As globalization and social changes are believed to be at the root of these epidemiological changes, these factors must be better understood. This study engaged older adults to gain an important perspective on globalization and health. METHODS: A free-list instrument and a structured survey were developed and used to gather data on changes in diet, activity, and women's roles from ten grandmothers in rural India...

Maternal obesity negatively impacts the placenta, being associated with increased inflammation, decreased mitochondrial respiration, decreased expression of brain-derived neurotrophic factor (BDNF), and its receptor, tropomyosin receptor kinase B (TRKB). TRKB induction by 7,8-dihydroxyflavone (7,8-DHF) improves energy expenditure in an obesity animal model. We hypothesized that TRKB activation would improve mitochondrial respiration in trophoblasts from placentas of obese women. Placentas were collected from lean (pre-pregnancy BMI < 25) and obese (pre-pregnancy BMI > 30) women at term following cesarean section delivery without labor...

This paper considers effects of body mass on wages in the years following labor market entry. The preferred models allow current wages to be affected by both past and current body mass, as well as past wages, while also addressing the endogeneity of body mass. I find that a history of severe obesity has a large negative effect on the wages of white men. White women face a penalty for a history of being overweight, with some evidence of additional penalties that begin above the threshold for severe obesity. Furthermore, the effects of past wages on current wages imply that past body mass has additional, indirect effects on wages, especially for white women...

BACKGROUND: The prevalence of morbid obesity (body mass index ≥40 kg/m(2)) in women aged 20-39 years was 7.5% in 2009 through 2010. Morbid obesity is associated with an increased risk of stillbirth compared with normal body mass index, especially >39 weeks' gestation. The data regarding increased risk of cesarean delivery associated with nonmedically indicated induction of labor compared to expectant management in morbidly obese women are limited. OBJECTIVE: We sought to compare the cesarean delivery rate of nonmedically indicated induction of labor with expectant management in morbidly obese women without other comorbidity...

OBJECTIVE: Studies show high comorbidity of mood disorders in asthma. As asthma is a highly heterogeneous disease with different phenotypes it can be expected that there is a difference in this association with different asthma phenotypes. The aim of our cross-sectional study was to assess the association of specific asthma phenotypes with anxiety and/or depression and their impact on asthma control. METHODS: A cross-sectional study in 201 consecutive adult outpatients with asthma (≥18 years of age) was conducted...

Relaxin, a systemic and placental hormone, has potential roles in fetoplacental growth. Human placenta expresses two RLN genes, RLNH1 and RLNH2 Maternal obesity is common and is associated with abnormal fetal growth. Our aims were to relate systemic and cord blood RLNH2, placental RLNs and their receptor (RXFP1) with fetoplacental growth in context of maternal body mass index, and associations with insulin-like growth factor 2 (IGF2) and vascular endothelial growth factor A (VEGFA) in the same placentas. Systemic, cord blood and placental samples were collected prior to term labor, divided by prepregnancy body mass index: underweight/normal (N = 25) and overweight/obese (N = 44)...

BACKGROUND/OBJECTIVES: Insulin resistance of adipose tissue is an important feature of obesity-related metabolic disease. However, assessment of lipolysis in humans requires labor-intensive and expensive methods, and there is limited validation of simplified measurement methods. We aimed to validate simplified methods for the quantification of adipose tissue insulin resistance against the assessment of insulin sensitivity of lipolysis suppression during hyperinsulinemic-euglycemic clamp studies...

BACKGROUND: Although oxytocin commonly is used to augment or induce labor, it is difficult to predict its effectiveness because oxytocin dose requirements vary significantly among women. One possibility is that women requiring high or low doses of oxytocin have variations in the oxytocin receptor gene. OBJECTIVES: To identify oxytocin receptor gene variants in laboring women with low and high oxytocin dosage requirements. STUDY DESIGN: Term, nulliparous women requiring oxytocin doses of ≤4 mU/min (low-dose-requiring, n = 83) or ≥20 mU/min (high-dose-requiring, n = 104) for labor augmentation or induction provided consent to a postpartum blood draw as a source of genomic DNA...

Mortality from esophageal cancer remains high despite advances in medical therapy. Although the incidence of squamous cell carcinoma of the esophagus remains unchanged, the incidence of the esophageal adenocarcinoma has increased over time. Gastroesophageal reflux disease (GERD and obesity are contributing factors to the development of Barrett's esophagus and subsequent development of adenocarcinoma. Early recognition of the disease can lead to resection of esophageal cancer prior to the development of lymphovascular invasion...

BACKGROUND: China has experienced a rapid growth in childhood adiposity in recent years. Although a large number of studies examine the effect of maternal employment on children's adiposity in developed countries, only a few studies investigate the issue in developing countries. Moreover, existing studies tend to suffer from a potential endogeneity issue. AIMS: We provide new evidence on the causal effect of maternal employment on children's adiposity in China. MATERIALS AND METHODS: We employ a difference-in-difference strategy that takes advantage of China's 1995 legislative change to labor regulations, which reduced the number of workdays from 6 to 5 days per week...
