Twin pregnancies contribute a disproportionate degree to perinatal morbidity, partly because of increased risks of low birth weight and prematurity. Although the cause of the morbidity is multifactorial, attention to twin-specific maternal nutrition may be beneficial in achieving optimal fetal growth and birth weight. Achievement of body mass index (BMI)-specific weight gain goals, micronutrient and macronutrient supplementation specific to the physiology of twin gestations, and carbohydrate-controlled diets are recommended for optimal twin growth and pregnancy outcomes. The daily recommended caloric intake for normal-BMI women with twins is 40-45 kcal/kg each day, and iron, folate, calcium, magnesium, and zinc supplementation is recommended beyond a usual prenatal vitamin. Daily supplementation of docosahexaenoic acid and vitamin D should also be considered. Multiple gestation-specific prenatal care settings with a focus on nutritional interventions improve birth weight and length of gestation and should be considered for the care of women carrying multiples. Antepartum lactation consultation can also improve the rate of postpartum breastfeeding in twin pregnancies. Twin gestation-specific nutritional interventions seem effective in improving the outcome of these pregnancies and should be emphasized in the antepartum care of multiple gestations. This review examines the available evidence and offers recommendations for twin pregnancy-specific nutritional interventions.

Much has been learned during the past several decades about the role of maternal nutrition in the outcome of pregnancy. While the bulk of the data is derived from animal models, human observations are gradually accumulating. There is need to improve maternal nutrition because of the high neonatal mortality rate especially in developing countries. The author used a conceptual framework which took both primary and secondary factors into account when interpreting study findings. Nutrition plays a vital role in reducing some of the health risks associated with pregnancy such as risk of fetal and infant mortality, intra-uterine growth retardation, low birth weight and premature births, decreased birth defects, cretinism, poor brain development and risk of infection. Adequate nutrition is essential for a woman throughout her life cycle to ensure proper development and prepare the reproductive life of the woman. Pregnant women require varied diets and increased nutrient intake to cope with the extra needs during pregnancy. Use of dietary supplements and fortified foods should be encouraged for pregnant women to ensure adequate supply of nutrients for both mother and foetus. The author concludes that nutrition education should be a core component of Mother and Child Health Clinics and every opportunity should be utilised to give nutrition education on appropriate diets for pregnant women.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease with a high prevalence in females of childbearing age. Thus, reproduction in SLE patients is a major concern for clinicians. In the past, SLE patients were advised to defer pregnancy because of poor pregnancy outcomes and fear of SLE flares during pregnancy. Investigations to date show that maternal and fetal risks are higher in females with SLE than in the general population. However, with appropriate management of the disease, sufferers may have a relatively uncomplicated pregnancy course. Factors such as appropriate preconception counseling and medication adjustment, strict disease control prior to pregnancy, intensive surveillance during and after pregnancy by both the obstetrician and rheumatologist, and appropriate interventions when necessary play a key role. This review describes the strategies to improve pregnancy outcomes in SLE patients at different time points in the reproduction cycle (preconception, during pregnancy, and postpartum period) and also details the neonatal concerns.

The female prison population has increased dramatically in recent years. Most women prisoners are involved with drugs, and as many as 25 percent are pregnant or have delivered within the past year. Reproductive health and drug treatment services for women in prison are inadequate, if they are available at all, and although illicit drugs are readily available in prison, drug-involved pregnant women often are incarcerated to protect fetal health. Studies of pregnancy outcome among women prisoners have demonstrated high rates of perinatal mortality and morbidity. This article examines issues related to pregnancy among women prisoners and describes an innovative residential program designed for pregnant, drug-dependent women in a state adult corrections system. Social workers can play an important role in promoting policy reform and improved services for this underserved population.

The significant increase in the prevalence of obesity has led to an increase in the number of obese women who become pregnant. In this setting, in recent years, there has been an exponential rise in the number of bariatric procedures, with approximately half of them performed in women of childbearing age, and a remarkable surge in the number of women who become pregnant after having undergone bariatric surgery (BS). These procedures entail the risk of nutritional deficiencies, and nutrition is a crucial aspect during pregnancy. Therefore, knowledge and awareness of the consequences of these techniques on maternal and fetal outcomes is essential. Current evidence suggests a better overall obstetric outcome after BS, in comparison to morbid obese women managed conservatively, with a reduction in the prevalence of gestational diabetes mellitus, pregnancy-associated hypertensive disorders, macrosomia, and congenital defects. However, the risk of potential maternal nutritional deficiencies and newborns small for gestational age cannot be overlooked. Results concerning the incidence of preterm delivery and the number of C-sections are less consistent. In this paper, we review the updated evidence regarding the impact of BS on pregnancy.

Parenthood is a central focus for women with chronic kidney disease, but raises important fears and uncertainties about risks to their own and their baby’s health. Pregnancy in women with background kidney disease, women receiving dialysis, or those with a functioning kidney transplant poses a challenging clinical scenario, associated with high maternal–fetal morbidity and potential impact on maternal renal health. Improvements in care over recent decades have led to a paradigm shift with cautious optimism and growing interest regarding pregnancies in women with chronic kidney disease. In this review, we discuss obstetric and renal outcomes, and practical aspects of management of pregnancy in this complex cohort. PMID:27471410

Until recently many physicians in the United States including obstetrician gynecologists have been relatively unconcerned with oral health. During most physical examinations, the oral cavity is given only a rudimentary examination. With the recognition of the oral-systemic health care link, physicians have been keenly interested in the findings from their dental colleagues in periodontal medicine which have convincingly linked periodontal disease with such diverse systemic health complications as aging, Alzheimer disease, cardiovascular disease, diabetes, and also pregnancy complications including low birth weight, preterm delivery, preeclampsia, and early pregnancy loss. Intervention trials designed to improve oral health during pregnancy have proven to be safe; however, the outcomes have been inconsistent. Further studies will be required to determine the nature of the association and the optimal timing and efficacy of intervention.

BACKGROUND. Administration of conventional antithrombotic treatment (low-dose aspirin plus low–molecular weight heparin [LDA+LMWH]) for obstetric antiphospholipid syndrome (APS) does not prevent life-threatening placenta insufficiency–associated complications such as preeclampsia (PE) and intrauterine growth restriction (IUGR) in 20% of patients. Statins have been linked to improved pregnancy outcomes in mouse models of PE and APS, possibly due to their protective effects on endothelium. Here, we investigated the use of pravastatin in LDA+LMWH-refractory APS in patients at an increased risk of adverse pregnancy outcomes. METHODS. We studied 21 pregnant women with APS who developed PE and/or IUGR during treatment with LDA+LMWH. A control group of 10 patients received only LDA+LMWH. Eleven patients received pravastatin (20 mg/d) in addition to LDA+LMWH at the onset of PE and/or IUGR. Uteroplacental blood hemodynamics, progression of PE features (hypertension and proteinuria), and fetal/neonatal outcomes were evaluated. RESULTS. In the control group, all deliveries occurred preterm and only 6 of 11 neonates survived. Of the 6 surviving neonates, 3 showed abnormal development. Patients who received both pravastatin and LDA+LMWH exhibited increased placental blood flow and improvements in PE features. These beneficial effects were observed as early as 10 days after pravastatin treatment onset. Pravastatin treatment combined with LDA+LMWH was also associated with live births that occurred close to full term in all patients. CONCLUSION. The present study suggests that pravastatin may improve pregnancy outcomes in women with refractory obstetric APS when taken at the onset of PE or IUGR until the end of pregnancy. PMID:27454295

The use of the conventional APS treatment (the combination of low-dose aspirin and LMWH) dramatically improved the obstetrical prognosis in primary obstetrical APS (OAPS). The persistence of adverse pregnancy outcome raises the need to find other drugs to improve obstetrical outcome. Hydroxychloroquine is widely used in patients with various autoimmune diseases, particularly SLE. Antimalarials have many anti-inflammatory, anti-aggregant and immune-regulatory properties: they inhibit phospholipase activity, stabilize lysosomal membranes, block the production of several pro-inflammatory cytokines and, in addition, impair complement-dependent antigen-antibody reactions. There is ample evidence of protective effects of hydroxychloroquine in OAPS similar to the situation in SLE arising from in vitro studies of pathophysiological working mechanism of hydroxychloroquine. However, the clinical data on the use of hydroxychloroquine in primary APS are lacking and prospective studies are necessary.

Adverse pregnancy outcomes significantly contribute to morbidity and mortality for mother and child, with lifelong health consequences for both. The innate and adaptive immune system must be regulated to insure survival of the feta allograft, and the complement system is no exception. An intact complement system optimizes placental development and function and is essential to maintain host defense and fetal survival. Complement regulation is apparent at the placental interface from early pregnancy with some degree of complement activation occurring normally throughout gestation. However, a number of pregnancy complications including early pregnancy loss, fetal growth restriction, hypertensive disorders of pregnancy and preterm birth are associated with excessive or misdirected complement activation, and are more frequent in women with inherited or acquired complement system disorders or complement gene mutations. Clinical studies employing complement biomarkers in plasma and urine implicate dysregulated complement activation in components of each of the adverse pregnancy outcomes. In addition, mechanistic studies in rat and mouse models of adverse pregnancy outcomes address the complement pathways or activation products of importance and allow critical analysis of the pathophysiology. Targeted complement therapeutics are already in use to control adverse pregnancy outcomes in select situations. A clearer understanding of the role of the complement system in both normal pregnancy and complicated or failed pregnancy will allow a rational approach to future therapeutic strategies for manipulating complement with the goal of mitigating adverse pregnancy outcomes, preserving host defense, and improving long term outcomes for both mother and child.

ABSTRACT Ready-to-eat (RTE) snacks are routinely distributed to pregnant women in India. These provide protein and calories but are low in micronutrients. We investigated whether RTE snacks fortified with leaf concentrate (LC) could improve pregnancy outcomes, including maternal haemoglobin (Hb) concentrations and infants’ birthweight. This randomized controlled two-arm trial was conducted over 18 months: control (sRTE) group received standard 120 g RTE snack (102 g wheat flour, 18 g soya flour); intervention (lcRTE) group received the same snack fortified with 7 g LC. The study was conducted in Jaipur, Rajasthan, India. One hundred and five pregnant women aged 18-35 years were studied. Among the 105 women randomized to the two arms of the trial, 2 (1.9%) were severely anaemic (Hb ≤6.0 g/dL); 55 (53.4%) were moderately anaemic (Hb 6.0-8.0 g/dL); 34 (33.0%) were mildly anaemic (Hb 8.6-10.9 g/dL); and 12 (11.7%) were not anaemic (Hb ≥11.0 g/dL). In the final month of pregnancy, 83.0% (39/47) of women in the sRTE group had Hb ≤8.5 g/dL compared to 37.8% (17/45) in the lcRTE group (p<0.001). After adjustment for age and baseline Hb concentration, the difference in Hb concentrations due to LC fortification was 0.94 g/dL (95% CI 6.8-12.0; p<0.001). Mean live birthweight in the lcRTE group was 2,695 g (SD 325 g) compared to 2,545 g (297 g) in the sRTE group (p=0.02). The lcRTE snacks increased infants’ birthweight by 133.7 g (95% CI 7.3-260.2; p=0.04) compared to sRTE snacks. Leaf concentrate fortification of antenatal protein-calorie snacks in a low-income setting in India protected against declining maternal haemoglobin concentrations and increased infants’ birthweight when compared with unfortified snacks. These findings require replication in a larger trial. PMID:25395906

Background Birth outcomes, such as preterm birth, low birth weight (LBW), and small for gestational age (SGA), are crucial indicators of child development and health. Purpose To evaluate whether home visits from public health nurses for high-risk pregnant women prevent adverse birth outcomes. Methods In this quasi-experimental cohort study in Kyoto city, Japan, high-risk pregnant women were defined as teenage girls (range 14–19 years old), women with a twin pregnancy, women who registered their pregnancy late, had a physical or mental illness, were of single marital status, non-Japanese women who were not fluent in Japanese, or elderly primiparas. We collected data from all high-risk pregnant women at pregnancy registration interviews held at a public health centers between 1 July 2011 and 30 June 2012, as well as birth outcomes when delivered from the Maternal and Child Health Handbook (N = 964), which is a record of prenatal check-ups, delivery, child development and vaccinations. Of these women, 622 women were selected based on the home-visit program propensity score-matched sample (pair of N = 311) and included in the analysis. Data were analyzed between January and June 2014. Results In the propensity score-matched sample, women who received the home-visit program had lower odds of preterm birth (odds ratio [OR], 0.62; 95% confidence interval [CI], 0.39 to 0.98) and showed a 0.55-week difference in gestational age (95% CI: 0.18 to 0.92) compared to the matched controlled sample. Although the program did not prevent LBW and SGA, children born to mothers who received the program showed an increase in birth weight by 107.8 g (95% CI: 27.0 to 188.5). Conclusion Home visits by public health nurses for high-risk pregnant women in Japan might be effective in preventing preterm birth, but not SGA. PMID:26348847

Background Between the 1970s and 1990s, the World Health Organization promoted traditional birth attendant (TBA) training as one strategy to reduce maternal and neonatal mortality. To date, evidence in support of TBA training is limited but promising for some mortality outcomes. Objectives To assess the effects of TBA training on health behaviours and pregnancy outcomes. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (18 June 2012), citation alerts from our work and reference lists of studies identified in the search. Selection criteria Published and unpublished randomised controlled trials (RCT), comparing trained versus untrained TBAs, additionally trained versus trained TBAs, or women cared for/living in areas served by TBAs. Data collection and analysis Three authors independently assessed study quality and extracted data in the original and first update review. Three authors and one external reviewer independently assessed study quality and two extracted data in this second update. Main results Six studies involving over 1345 TBAs, more than 32,000 women and approximately 57,000 births that examined the effects of TBA training for trained versus untrained TBAs (one study) and additionally trained TBA training versus trained TBAs (five studies) are included in this review. These studies consist of individual randomised trials (two studies) and cluster-randomised trials (four studies). The primary outcomes across the sample of studies were perinatal deaths, stillbirths and neonatal deaths (early, late and overall). Trained TBAs versus untrained TBAs: one cluster-randomised trial found a significantly lower perinatal death rate in the trained versus untrained TBA clusters (adjusted odds ratio (OR) 0.70, 95% confidence interval (CI) 0.59 to 0.83), lower stillbirth rate (adjusted OR 0.69, 95% CI 0.57 to 0.83) and lower neonatal death rate (adjusted OR 0.71, 95% CI 0.61 to 0.82). This study also found the maternal death
Background 5% of first time pregnancies are complicated by pre-eclampsia, the leading cause of maternal death in Europe. No clinically useful screening test exists; consequentially clinicians are unable to offer targeted surveillance or preventative strategies. IMPROvED Consortium members have pioneered a personalised medicine approach to identifying blood-borne biomarkers through recent technological advancements, involving mapping of the blood metabolome and proteome. The key objective is to develop a sensitive, specific, high-throughput and economically viable early pregnancy screening test for pre-eclampsia. Methods/Design We report the design of a multicentre, phase IIa clinical study aiming to recruit 5000 low risk primiparous women to assess and refine innovative prototype tests based on emerging metabolomic and proteomic technologies. Participation involves maternal phlebotomy at 15 and 20 weeks’ gestation, with optional testing and biobanking at 11 and 34 weeks. Blood samples will be analysed using two innovative, proprietary prototype platforms; one metabolomic based and one proteomic based, both of which outperform current biomarker based screening tests at comparable gestations. Analytical and clinical data will be collated and analysed via the Copenhagen Trials Unit. Discussion The IMPROvED study is expected to refine proteomic and metabolomic panels, combined with clinical parameters, and evaluate clinical applicability as an early pregnancy predictive test for pre-eclampsia. If ‘at risk’ patients can be identified, this will allow stratified care with personalised fetal and maternal surveillance, early diagnosis, timely intervention, and significant health economic savings. The IMPROvED biobank will be accessible to the European scientific community for high quality research into the cause and prevention of adverse pregnancy outcome. Trial registration Trial registration number NCT01891240 The IMPROvED project is funded by the seventh framework

Lipids play an important role during pregnancy, and in this period major changes occur in lipoprotein metabolism. During the third trimester plasma cholesterol and triglyceride levels are substantially increased, returning to normal after delivery. Described associations between increased morbidity during pregnancy and excessive increases in plasma cholesterol and triglycerides. For this reason we have reviewed the relationship between lipid alterations, preeclampsia, gestational diabetes and preterm birth. The overall metabolic control can improve pregnancy outcomes, and the assessment of supraphysiological changes in lipid profile will classify pregnancy risk at a higher level, which would entail a stricter control.
Background In pregnancy, violence can have serious health consequences that could affect both mother and child. In Ghana there are limited data on this subject. We sought to assess the relationship between physical violence during pregnancy and pregnancy outcomes (early pregnancy loss, perinatal mortality and neonatal mortality) in Ghana. Method The 2008 Ghana Demographic and Health Survey data were used. For the domestic violence module, 2563 women were approached of whom 2442 women completed the module. After excluding missing values and applying the weight factor, 1745 women remained. Logistic regression analysis was performed to assess the relationship between physical violence in pregnancy and adverse pregnancy outcomes with adjustments for potential confounders. Results About five percent of the women experienced violence during their pregnancy. Physical violence in pregnancy was positively associated with perinatal mortality and neonatal mortality, but not with early pregnancy loss. The differences remained largely unchanged after adjustment for age, parity, education level, wealth status, marital status and place of residence: adjusted odds ratios were 2.32; 95% CI: 1.34-4.01 for perinatal mortality, 1.86; 95% CI: 1.05-3.30 for neonatal mortality and 1.16; 95% CI: 0.60-2.24 for early pregnancy loss. Conclusion Our findings suggest that violence during pregnancy is related to adverse pregnancy outcomes in Ghana. Major efforts are needed to tackle violence during pregnancy. This can be achieved through measures that are directed towards the right target groups. Measures should include education, empowerment and improving socio-economic status of women. PMID:24528555

The study was conducted to evaluate the effect of anticoagulant therapy in women with thrombophilia and to detect the possible differences among carriers of mutations (factor V [FV] Leiden and FIIG20210) and those with natural anticoagulant deficiency. The 4-year prospective investigation included 85 pregnant women, with a history of recurrent fetal loss (RFL). They were treated with prophylactic doses of low-molecular-weight heparin (nadroparin) starting from 6 to 8 weeks of gestation. Pregnancy outcomes were evaluated based on the thrombophilia type. Carriers of thrombophilic mutations had a live birth rate of 93%, compared to 41.6% for women with natural anticoagulant deficiencies. Significant differences between the groups were also observed for intrauterine fetal death, intrauterine growth restriction, and postpartum thrombosis. The optimal therapy for women with natural anticoagulant deficiency and RFL remains unclear and future prospective study with a large number of patients is required to determine the best treatment for these severe thrombophilic conditions.
Background Obesity is a significant global health problem, with the proportion of women entering pregnancy with a body mass index greater than or equal to 25 kg/m2 approaching 50%. Obesity during pregnancy is associated with a well-recognised increased risk of adverse health outcomes both for the woman and her infant, however there is more limited information available regarding effective interventions to improve health outcomes. The aims of this randomised controlled trial are to assess whether the implementation of a package of dietary and lifestyle advice to overweight and obese women during pregnancy to limit gestational weight gain is effective in improving maternal, fetal and infant health outcomes. Methods/Design Design: Multicentred randomised, controlled trial. Inclusion Criteria: Women with a singleton, live gestation between 10+0-20+0 weeks who are obese or overweight (defined as body mass index greater than or equal to 25 kg/m2), at the first antenatal visit. Trial Entry & Randomisation: Eligible, consenting women will be randomised between 10+0 and 20+0 weeks gestation using a central telephone randomisation service, and randomisation schedule prepared by non-clinical research staff with balanced variable blocks. Stratification will be according to maternal BMI at trial entry, parity, and centre where planned to give birth. Treatment Schedules: Women randomised to the Dietary and Lifestyle Advice Group will receive a series of inputs from research assistants and research dietician to limit gestational weight gain, and will include a combination of dietary, exercise and behavioural strategies. Women randomised to the Standard Care Group will continue to receive their pregnancy care according to local hospital guidelines, which does not currently include routine provision of dietary, lifestyle and behavioural advice. Outcome assessors will be blinded to the allocated treatment group. Primary Study Outcome: infant large for gestational age (defined as
In developing countries, 1/3 of infants are born weighing less than 2500 grams. A study conducted in Ethiopia among women consuming about 1600 kcal/day, those who were very physically active during pregnancy bore smaller babies, and gained less weight during pregnancy, than those who were not so active. Average birth weight was 3068 grams for the 1st group, 3270 grams for the less active. The active group of women gained an average of 6.5 kilograms, and the less active 9.2 kilograms. Women who did not engage in heavy work during pregnancy, although they were undernourished, apparently did not bear growth-retarded babies. Indirect evidence for the effect of physical activity on pregnancy outcome comes from studies conducted in Taiwan, and the Gambia. These studies, and others from Malawi, Burkina Faso, and Kenya have shown that women's energy expenditures vary greatly with the agricultural season. Daily housekeeping tasks, however, also consume a lot of women's energy. Technologies that allow women to reduce energy expenditure can have beneficial effects, if they do not simultaneously reduce their incomes. For instance, programs improving water or fuel availability, or reducing fuel needs, reduce women's energy expenditures. Food processing mills can help too if women have access to them, and are thus not in danger of being displaced from their jobs and losing necessary income. Examples of technology improving women's tasks are pedal drying machines for nice in Bangladesh, using a greater and pressing machine to prepare gari in Ghana; but growing thicker rice stalks in Indonesia displaced women workers and reduced income.

Pregnancy represents a time of rapid change, including dramatic shifts in vitamin D metabolism. Circulating concentrations of the active form of vitamin D-1,25(OH)2D skyrocket early in pregnancy to levels that would be toxic to a nonpregnant adult, signaling a decoupling of vitamin D from the classic endocrine calcium metabolic pathway, likely serving an immunomodulatory function in the mother and her developing fetus. In this review, we summarize the unique aspects of vitamin D metabolism and the data surrounding vitamin D requirements during this important period. Both observational and clinical trials are reviewed in the context of vitamin D's health effects during pregnancy that include preeclampsia, preterm birth, and later disease states such as asthma and multiple sclerosis. With enhanced knowledge about vitamin D's role as a preprohormone, it is clear that recommendations about supplementation must mirror what is clinically relevant and evidence-based. Future research that focuses on the critical period(s) leading up to conception and during pregnancy to correct deficiency or maintain optimal vitamin D status remains to be studied. In addition, what effects vitamin D has on genetic signatures that minimize the risk to the mother and her developing fetus have not been elucidated. Clearly, while there is much more research that needs to be performed, our understanding of vitamin D requirements during pregnancy has advanced significantly during the last few decades.

Aims To examine the relationship between personality, pregnancy and birth outcomes in adolescents Background Personality has been shown to be a strong predictor of many health outcomes. Adolescents who become pregnant have worse birth outcomes than adults. Design Cross-sectional study using data from the National Longitudinal Study of Adolescent Health (baseline, 1994-1995; follow-up, 2007-2008). Methods The study sample was 6529 girls, 820 of whom reported on pregnancy outcomes for a teenage birth. Personality data was taken from the Mini International Personality Item Pool personality tool, which measures the five-factor personality traits of neuroticism, conscientiousness, intellect/imagination, extraversion and agreeableness. Logistic regression was used to predict teen pregnancy and linear regression was used to predict birth weight and gestational age with adjustment for confounders and stratification by race. Results Agreeableness and intellect/imagination were associated with a reduced likelihood of becoming pregnant as an adolescent, while neuroticism, conscientiousness and extraversion were all associated with an increased likelihood of becoming pregnant. Higher neuroticism was associated with lower birth weight and gestational age among Black girls, but not non-Black. Conscientiousness was associated with lower gestational age among non-Black girls. No relationships were found with extraversion or agreeableness and birth outcomes. Receiving late or no prenatal care was associated with higher intellect/imagination. Conclusions Personality is understudied with respect to pregnancy and birth outcomes compared with other health outcomes. Such research could help professionals and clinicians design and target programs that best fit the characteristics of the population most likely to need them, such as those with high neuroticism.

Abstract Pregnancy and childbirth represent a critical time period when a woman can be reached through a variety of mechanisms with interventions aimed at reducing her risk of a preterm birth and improving her health and the health of her unborn baby. These mechanisms include the range of services delivered during antenatal care for all pregnant women and women at high risk of preterm birth, services provided to manage preterm labour, and workplace, professional and other supportive policies that promote safe motherhood and universal access to care before, during and after pregnancy. The aim of this paper is to present the latest information about available interventions that can be delivered during pregnancy to reduce preterm birth rates and improve the health outcomes of the premature baby, and to identify data gaps. The paper also focuses on promising avenues of research on the pregnancy period that will contribute to a better understanding of the causes of preterm birth and ability to design interventions at the policy, health care system and community levels. At minimum, countries need to ensure equitable access to comprehensive antenatal care, quality childbirth services and emergency obstetric care. Antenatal care services should include screening for and management of women at high risk of preterm birth, screening for and treatment of infections, and nutritional support and counselling. Health workers need to be trained and equipped to provide effective and timely clinical management of women in preterm labour to improve the survival chances of the preterm baby. Implementation strategies must be developed to increase the uptake by providers of proven interventions such as antenatal corticosteroids and to reduce harmful practices such as non-medically indicated inductions of labour and caesarean births before 39 weeks of gestation. Behavioural and community-based interventions that can lead to reductions in smoking and violence against women need to be

Cohort analysis has been the cornerstone of tuberculosis (TB) monitoring and evaluation for nearly two decades; these principles have been adapted for patients with the human immunodeficiency virus/acquired immune-deficiency syndrome on antiretroviral treatment and patients with diabetes mellitus and hypertension. We now make the case for using cohort analyses for monitoring pregnant women during antenatal care, up to and including childbirth. We believe that this approach would strengthen the current monitoring and evaluation systems used in antenatal care by providing more precise information at regular time intervals. Accurate real-time data on how many pregnant women are enrolled in antenatal care, their characteristics, the interventions they are receiving and the outcomes for mother and child should provide a solid basis for action to reduce maternal mortality.

Immune regulation during pregnancy is complex, and thus an optimal therapy for pregnancy complications is always a big challenge to reproductive medicine. Cyclosporin A (CsA), a potent immunosuppressant, prevents rejection of allografts by hosts, but little is known about the modulating effect of CsA on the materno-fetal relationship. Here, pregnant CBA/J females mated with DBA/2 males as an abortion-prone model were administered with CsA on day 4.5 of gestation, and the pregnant CBA/J females mated with BALB/c males were established as successful pregnancy control. It was demonstrated that administration of CsA at the window of implantation significantly up-regulated the expression of CTLA-4, while down-regulating the levels of CD80, CD86, and CD28 at the materno-fetal interface in the CBA/J x DBA/2 abortion-prone matings, and the embryo resorption rate of the abortion-prone matings reduced significantly after CsA treatment, implying that modulation of costimulatory molecule expression by CsA might contribute to preventing the fetus from maternal immune attack. In addition, treatment with CsA induced enhanced growth and reduced cell apoptosis of the murine trophoblast cells. Together, these findings indicate that CsA has a beneficial effect on the materno-fetal interface in abortion-prone matings, leading to a pregnancy outcome improvement, which might provide new therapeutics for spontaneous pregnancy wastage.

Unicornuate uterus with rudimentary horn is an uncommon type of mullerian duct malformation associated with various gynecological and obstetrical complications. Rudimentary horn pregnancy is a rare entity and the majority have rupture of gravid horn leading to maternal and fetal morbidity and mortality. A case of rudimentary horn pregnancy at 32 weeks and 6 days with pregnancy induced hypertension is reported where proper management results in successful pregnancy outcome.

Introduction Previous systematic reviews concluded that rigorous research on the relationships between pregnancy intentions and pregnancy outcomes is limited. They further noted that most studies were conducted in high-income countries and had methodological limitations. We aim to assess the current evidence base for the relationship between pregnancy intention and miscarriage, stillbirth, low birthweight (LBW) and neonatal mortality. In March 2015 Embase, PubMed, Scopus and PsychInfo were searched for studies investigating the relationship between pregnancy intention and the outcomes of interest. Methods Studies published since 1975 and in English, French or Spanish were included. Two reviewers screened titles and abstracts, read the full text of identified articles and extracted data. Meta-analyses were conducted where possible. Results Thirty-seven studies assessing the relationships between pregnancy intention and LBW were identified. A meta-analysis of 17 of these studies found that unintended pregnancies are associated with 1.41 times greater odds of having a LBW baby (95%CI 1.31, 1.51). Eight studies looking at miscarriage, stillbirth or neonatal death were found. The limited data concerning pregnancy loss and neonatal mortality precluded meta-analysis but suggest these outcomes may be more common in unintended pregnancies. Discussion While there seems to be an increased risk of adverse pregnancy outcome in unintended pregnancies, there has been little improvement in either the quantity of evidence from low-income countries or in the quality of evidence generally. Longitudinal studies of pregnancy intention and pregnancy outcome, where pregnancy intention is assessed prospectively with a validated measure and where analyses include confounding or mediating factors, are required in both high- and low-income countries.

Maternal nutritional status during pregnancy will affect the outcomes for the mother and the baby. Many analyses of the relationship between diet and outcome are often based on a single or a few food items or nutrients. However, foods are not consumed in isolation and dietary patterns can be used to assess the whole diet consumed. The use of dietary pattern analysis to understand nutritional intake and pregnancy outcome is becoming more and more popular. Many published studies have showed the association between maternal dietary patterns and pregnancy outcome. This review examined articles about the relationship between maternal dietary patterns and pregnancy outcome. As a modifiable factor, dietary patterns may be more applicable to clinical and pregnant health interventions. PMID:27338455

The purpose of this study is to evaluate the relationship between maternal and/or cord blood folate/homocysteine concentrations and adverse pregnancy outcomes. The study population included a random sample of singleton pregnant women in whom we measured total homocysteine and folic acid in maternal or cord blood at deliveries. A total of 227 pregnant women were enrolled. The concentration of folate in maternal blood tended to be significantly lower in pre-term birth than in full-term delivery group (median (95% CI), 14.4 (3.6-73) vs 25 (7.3-105.5) p < 0.01). The total homocysteine in maternal and cord blood was significantly higher in the pre-eclampsia than in the normotensive group (7.9 (1.7-28.2) vs 5.9 (1.8-14.6) μmol/ml, p < 0.05; and 5.8 (2.6-14.4) vs 4.2 (0.7-7.9) ng/ml, p < 0.05, respectively). Lower maternal serum folate concentration is associated with pre-term delivery and higher maternal plasma homocysteine concentration with pre-eclampsia.
There are several reasons why metformin treatment may be considered for women in neuropsychiatric practice. These include prevention or attenuation of antipsychotic-associated weight gain, prevention or treatment of gestational diabetes mellitus (GDM), treatment of type 2 diabetes mellitus, and improvement of conception chances and pregnancy outcomes in the presence of polycystic ovarian disease (PCOD). This article examines the benefits and risks associated with metformin use during pregnancy. The available data suggest that metformin exposure during the first trimester is not associated with major congenital malformations; that metformin reduces the risk of early pregnancy loss, preeclampsia, preterm delivery, and GDM in women with PCOD; that metformin is associated with at least comparable benefits relative to insulin treatment in women with mild GDM; and that neurodevelopmental outcomes at age 1.5-2.5 years are comparable after gestational exposure to metformin and insulin. Whereas study designs were not always ideal and sample sizes were mostly small to modest, the study findings are more encouraging than discouraging and can guide shared decision-making in women who are receiving or may need metformin during pregnancy.

Objective To evaluate whether the presence of condition-specific obstetric protocols within a hospital was associated with better maternal and neonatal outcomes. Study Design Cohort study of a random sample of deliveries performed at 25 hospitals over three years. Condition-specific protocols were collected from all hospitals and categorized independently by two authors. Data on maternal and neonatal outcomes, as well as data necessary for risk adjustment were collected. Risk-adjusted outcomes were compared according to whether the patient delivered in a hospital with condition-specific obstetric protocols at the time of delivery. Results Hemorrhage-specific protocols were not associated with a lower rate of postpartum hemorrhage or with fewer cases of EBL >1000cc. Similarly, in the presence of a shoulder dystocia protocol, there were no differences in the frequency of shoulder dystocia or number of shoulder dystocia maneuvers used. Conversely, preeclampsia-specific protocols were associated with fewer ICU admissions (OR 0.28, 95% CI 0.18–0.44) and fewer cases of severe maternal hypertension (OR 0.86, 95% CI 0.77–0.96). Conclusion The presence of condition-specific obstetric protocols was not consistently shown to be associated with improved risk-adjusted outcomes. Our study would suggest that the presence or absence of a protocol does not matter and regulations to require protocols are not fruitful. PMID:25659468

Background: Isotretinoin, a teratogen, is widely used to treat cystic acne. Although the risks of pregnancy during isotretinoin therapy are well recognized, there are doubts about the level of adherence with the pregnancy prevention program in Canada. Our objective was to evaluate the effectiveness of the Canadian pregnancy prevention program in 4 provinces: British Columbia, Saskatchewan, Manitoba and Ontario. Methods: Using administrative data, we identified 4 historical cohorts of female users of isotretinoin (aged 12–48 yr) for the period 1996 to 2011. We defined pregnancy using International Statistical Classification of Diseases and billing codes. One definition included only cases with documented pregnancy outcomes (high-specificity definition); the other definition also included individuals recorded as receiving prenatal care (high-sensitivity definition). We studied new courses of isotretinoin and detected pregnancies in 2 time windows: during isotretinoin treatment only and up to 42 weeks after treatment. Live births were followed for 1 year to identify congenital malformations. Results: A total of 59 271 female patients received 102 308 courses of isotretinoin. Between 24.3% and 32.9% of participants received prescriptions for oral contraceptives while they were taking isotretinoin, compared with 28.3% to 35.9% in the 12 months before isotretinoin was started. According to the high-specificity definition of pregnancy, there were 186 pregnancies during isotretinoin treatment (3.1/1000 isotretinoin users), compared with 367 (6.2/1000 users) according to the high-sensitivity definition. By 42 weeks after treatment, there were 1473 pregnancies (24.9/1000 users), according to the high-specificity definition. Of these, 1331 (90.4%) terminated spontaneously or were terminated by medical intervention. Among the 118 live births were 11 (9.3%) cases of congenital malformation. Pregnancy rates during isotretinoin treatment remained constant between 1996 and 2011

Hypericum perforatum (HP; also known as St. John's Wort) is one of the most commonly used herbal therapies in the management of depressive illness. The aim of this study was to evaluate the potential side effects of HP during pregnancy on pregnancy outcome. Using data from the Danish National Birth Cohort (DNBC), we investigated outcomes among 38 HP exposed pregnancies compared to a group of 90,128 women. Associations between HP use and gestational age, preterm birth, birth weight, malformations and Apgar scores were investigated. Preterm birth did not differ across the groups. While the prevalence of malformations in the HP exposed group was slightly higher (8.1%) than observed in the control groups (3.3%; p=0.13), this was based on only three cases and was not of any specific pattern.

Thiocolchicoside is a commonly used muscle relaxant in orthopedic, rheumatologic or musculoskeletal disorders to treat painful muscle spasms. It is contraindicated in pregnancy and lactation. There is no previously published experience with thiocolchicoside exposure during pregnancy. In this observational study, we collected and evaluated 18 pregnancy outcomes of the women referred to our prenatal consultation service for thiocolchicoside exposure between 2007-2012, and offspring were followed up until 2 years of age. There were 16 live births, 1 spontaneous abortion and 1 elective termination of pregnancy. No major birth defect was observed. The mothers and their babies were free of perinatal complications. No growth or developmental abnormalities were found during follow-up period. Our findings add information on inadvertent use of thiocolchicoside in pregnancy. Further large prospective cohort studies are required to investigate this issue.

A sample of 750 women were interviewed during pregnancy on their depression and anxiety symptoms, substance use and demographic variables. A subsample was seen again at the neonatal stage (n = 152), and their infants were observed for sleep-wake behavior. Symptoms of depression and anxiety were related to caffeine use. Mothers who consumed more…

This was a hospital based prospective clinical study conducted among women having prolonged pregnancy to assess the outcome of induction of labour in prolonged pregnancy cases. One hundred and thirty nine women having uncomplicated prolonged pregnancy were studied. The study was carried out in Sir Salimullah Medical College & Mitford Hospital, Dhaka from 01 July 2010 to 30 March 2011. In this study 66% of the respondents had vaginal delivery on routine induction of labour and in 34% cases induction failed. Ninety three percent (93%) of the multigravida had vaginal delivery and in primigravida their vaginal delivery rate was 47.5%. Regarding cervical condition for delivery, 75% of the respondents having favourable cervix had vaginal delivery and in case of unfavourable cervix respondents, they had 55% cases of vaginal delivery. About the foetal outcome it was evidenced from this study that the perinatal adverse outcome increases with the increasing age of gestation beyond 40 completed weeks of gestation. This study showed that the use of prostaglandins for cervical ripening and by confirming the diagnosis of prolonged pregnancy, the delivery outcome in prolonged pregnancy can be improved. The study also showed that induction of labour is not associated with any major complications and the routine induction of labour in prolonged pregnancy is beneficial for both mother and the baby.

The treatment of epilepsy in women of reproductive age remains a clinical challenge. While most women with epilepsy require anticonvulsant drugs for adequate control of their seizures, the teratogenicity associated with some antiepileptic drugs is a risk that needs to be carefully addressed. Antiepileptic medications are also used to treat an ever broadening range of medical conditions such as bipolar disorder, migraine prophylaxis, cancer and neuropathic pain. Despite the fact that the majority of pregnancies of women with epilepsy who are receiving pharmacological treatment are normal, studies have demonstrated that the risk of having a pregnancy complicated by a major congenital malformation is doubled when comparing the risk of untreated pregnancies. Furthermore, when antiepileptic drugs (AEDs) are used in polytherapy regimens, the risk is tripled, especially when valproic acid (VPA) is included. However, it should be noted that the risks are specific for each anticonvulsant drug. Some investigations have suggested that the risk of teratogenicity is increased in a dose-dependent manner. More recent studies have reported that in utero exposure to AEDs can have detrimental effects on the cognitive functions and language skills in later stages of life. In fact, the FDA just issued a safety announcement on the impact of VPA on cognition (Safety Announcement 6-30-2011). The purpose of this document is to review the most commonly used compounds in the treatment of women with epilepsy, and to provide information on the latest experimental and human epidemiological studies of the effects of antiepileptic drugs in the exposed embryos.

Although the association of fetal growth restriction and adverse pregnancy outcomes is well known, lack of sensitivity limits its clinical value. To a large extent, this limitation is a result of traditionally used method to define growth restriction by comparing fetal or birth weight to population norms. The use of population norms, by virtue of their inability to fully consider individual variation, results in high false positive and negative rates. An alternative, calculating fetal individually optimal growth potential, based on physiological determinants of individual growth, is superior in predicting adverse outcomes of pregnancy. Impairment of fetal growth potential identifes some adverse pregnancy outcomes that are not associated with growth restrction defined by population norms. When compared with traditional population-based norms, fetal growth potential is a better predictor of several important adverse outcomes of pregnancy which include: stillbirth, neonatal mortality and morbidity, and long-term adverse neonatal outcomes like neonatal encephalopathy, cerebral palsy and cognitive abilities. Impairment of individual growth potential is also strongly associated with spontaneous preterm delivery. Although definitive interventional trials have not been conducted as yet to validate the clinical value of fetal growth potential, many observational studies, conducted in various populations, indicate its significant promise in this respect.
normal growth and development of offspring during early life. In addition, the NTP monograph provides background materials on individual cancer chemotherapeutic agents (e.g., evidence for placenta and breast milk transport, developmental toxicity in animals), and a brief review of the prevalence and prognosis of seven frequently diagnosed cancers in women during pregnancy. Finally, the NTP monograph identifies challenges in interpreting the health outcomes from this observational literature base and discussed possible actions to improve the understanding of the developmental effects of chemotherapy treatment for cancer administered during pregnancy.

The aim was to investigate whether dietary supplementation of a combination of the two antioxidants, vitamin E and vitamin C, would protect the fetus in diabetic rat pregnancy at a lower dose than previously used. Normal and streptozotocin-induced diabetic rats were mated and given standard food or food supplemented with either 0.5% vitamin E + 1% vitamin C or 2% vitamin E + 4% vitamin C. At gestational d 20, gross morphology and weights of fetuses were evaluated. Vitamins E and C and thiobarbituric acid reactive substances were measured in maternal and fetal compartments. In addition, protein carbonylation was estimated in fetal liver. Maternal diabetes increased the rate of malformation and resorption in the offspring. High-dose antioxidant supplementation decreased fetal dysmorphogenesis to near normal levels. The low-dose group showed malformations and resorptions at an intermediate rate between the untreated and the high-dose groups. Thiobarbituric acid reactive substances were increased in fetal livers of diabetic rats and reduced to normal levels already by low-dose antioxidative treatment. Protein carbonylation rate was also increased in fetal liver of diabetic rats; it was normalized by high-dose treatment but only partially reduced by low-dose antioxidants. We conclude that combined antioxidative treatment with vitamins E and C decreases fetal malformation rate and diminishes oxygen radical-related tissue damage. However, no synergistic effect between the two antioxidants was noted, a result that may influence future attempts to design antiteratogenic treatments in diabetic pregnancy. Oxidatively modified proteins may be teratogenically important mediators in diabetic embryopathy.

Studies have indicated that various societal factors such as toxicant exposure, maternal habits, occupational hazards, psychosocial factors, socioeconomic status, racial disparity, chronic stress, and infection may impact pregnancy outcomes. These outcomes include spontaneous abortion, preterm birth, alterations in the development of the fetus, and long-term health of offspring. Although much is known about individual pregnancy outcomes, little is known about the associations between societal factors and pregnancy outcomes. This manuscript reviews some of the literature available on the effects of the above-mentioned societal factors on pregnancy outcomes and examines some potential remedies for preventing adverse pregnancy outcomes in the future.

Abstract Background. Pregnancy occurs among 1–7% of women on chronic dialysis. Experience regarding pregnancy and dialysis originates from anecdotal reports, case series and surveys. This survey updates the US nephrologists’ experience with pregnancy on hemodialysis (HD) over the past 5 years. We evaluated maternal and fetal outcomes, certain practice patterns such as dialysis regimens utilized and nephrologist knowledge and comfort level when caring for a pregnant patient on HD. Methods. An anonymous Internet-based 23-question survey was e-mailed to end-stage renal disease Networks of America program directors for forwarding to practicing nephrologists. Results. A total of 196 nephrologists responded to the survey, reporting >187 pregnancies. Of the respondents, 45% had cared for pregnant females on HD and 78% of pregnancies resulted in live births. In 44% of the pregnancies a diagnosis of preeclampsia was made. There were no maternal deaths. Nephrologists most commonly prescribe 4–4.5 h of HD 6 days/week for pregnant women on dialysis. Women dialyzed cumulatively for >20 h/week were 2.2 times more likely to develop preeclampsia than those who received ≤20 h of HD per week. Conclusion. Providing intensive HD is a common treatment approach when dialyzing pregnant women. Maternal and fetal outcomes can be improved. There is a trend toward better live birthrates with more intense HD. Whether more cumulative hours of dialysis per week increases the risk of preeclampsia needs to be further investigated.

Background: Necrotizing Enterocolitis (NEC) is the most common gastrointestinal emergency in neonates. Previously established risk factors for the development of NEC include prematurity and low birth weight. However, it is not clear to date as to whether the etiology of NEC is due to host, environmental, or yet other unknown factors. We analyzed the differences in incidence of NEC in twin pregnancies to further clarify its etio-pathogenesis. Methods: After IRB approval, a retrospective search of the medical records of the Department of Pediatric Surgery was done to identify all the neonates treated for surgical NEC from 2006-2013. Patients that had been treated for NEC elsewhere and subsequently transferred in to our facility were excluded. The medical records of the resulting 45 patients were then analyzed for demographics, antenatal screening, risk factors, treatment (medical and surgical), and outcomes. The resulting data was then analyzed using relative risk calculations and standard statistical tests. Results: Of the 45 patients who developed surgical NEC, 9 neonates (20%) were born of a twin pregnancy. There were no cases in which both twin A and twin B developed NEC. NEC in twin pregnancy neonates showed a female preponderance (p less than 0.0001) and developed universally in the first born of the twins. Birth weight, time of onset of NEC, hospital stay and mortality were similar between twin and non-twin NEC. There was an average lead-time of three weeks to development of NEC in both singletons and twin pregnancies. Conclusion: There is a remarkable higher incidence of NEC amongst twins. Abnormal colonization of the gastrointestinal tract appears to be an immediate postpartum event. NEC in twin pregnancy does not appear to have a deleterious outcome compared to NEC in singleton pregnancy. PMID:26023516

Antiphospholipid antibodies, which include lupus-like anticoagulant and anticardiolipin antibody, have been linked to a number of adverse pregnancy outcomes, although their exact pathogenic mechanisms remain poorly defined. The relative risk of complications such as intrauterine growth retardation, spontaneous abortions, and stillbirth in patients with antiphospholipid antibodies also remains undetermined. Heightened attention has been focused on the association, leading to investigations into the pathogenesis. Uncontrolled studies have also explored therapeutic regimens such as aspirin, steroids, and heparin, and clinical trials have used various treatment protocols. Although knowledge into the association of antiphospholipid antibodies and recurrent adverse pregnancy outcome is limited and continues to evolve, this association provides new insights into the disease and offers promise for pharmacologic prophylaxis. In this article, current concepts on pathogenesis, diagnosis, and therapy are reviewed and recommendations are made for clinical care of these patients.

An increasing number of pregnancies occur in the presence of chronic kidney diseases (CKD), mainly including chronic glomerulonephritis (GN), diabetic nephropathy (DN), and lupus nephritis (LN). The most important factor affecting fetal and maternal prognosis is the degree of renal function at conception. In the majority of patients with mild renal function impairment, and well-controlled blood pressure, pregnancy is usually successful and does not alter the natural course of maternal renal disease. Conversely, fetal outcome and long-term maternal renal function might be seriously threatened by pregnancy in women with moderate or severe renal function impairment. The last few years, advances in our knowledge about the interaction of pregnancy and renal function resulted in the improvement of fetal outcome in patients with chronic renal failure and also in the management of pregnant women with end-stage renal disease (ESRD) maintained on dialysis. However, women with impaired renal function and those on dialysis should be carefully counseled about the risks of pregnancy.

Few studies have considered the differing impact of socioeconomic factors on pregnancy outcomes among racial subgroups. We assessed pregnancy outcome by race, education, and income (poverty index), using data from the Pregnancy, Infection, and Nutrition Study, a cohort study of preterm birth in central North Carolina, using binomial regression. Poverty was associated with an increased risk of preterm birth only among African Americans with 12 or more years of education (RR=1.6, 95% CI: 1.1, 2.2). White participants with both a low level of education and an income below the poverty line were at increased risk of preterm birth (RR=1.7, 95% CI: 1.1, 2.7). White women with 12 or more years of education had increased risk of small-for-gestational-age birth (SGA, defined as <10th percentile of birth weight for gestational age) associated with poverty status (RR=1.7, 95% CI: 1.1, 2.7). Socioeconomic indicators appear to have complex joint effect patterns among racial subgroups, perhaps because the material and psychological implications of education and income status differ between groups.

This study describes the perinatal characteristics of Cambodian refugees in Massachusetts. Data were abstracted from the records of 452 consecutive pregnancies among Cambodian women and 110 low-income Whites receiving obstetrical services at the same clinic and hospital in Lowell, Massachusetts. Pregnancies of Cambodian women were marked by a higher proportion of older mothers, grand multiparas, previous adverse birth outcomes, and short interpregnancy intervals. We identified maternal anemia (29.9 percent with hemoglobin less than 110 g/L) and inadequate utilization of prenatal care (32.3 percent with first visit in the 3rd trimester) as possible risk factors for the Cambodians. The prevalence of primary cesarean birth was only 6.3 percent in the Cambodians, compared to 15.6 percent in the comparison group, largely due to the infrequent occurrence of prolonged labor among multiparas. Despite the prominence of several risk factors for adverse birth outcomes in this population, major pregnancy complications were less common and the prevalence of low birthweight (6.4 percent) was close to the state average. Logistic regression analysis of risk factors for low birthweight identified young maternal age and short stature as the strongest factors operative in this community. Many of our findings are consistent with a strong cultural emphasis on managing the size of the baby to avoid a difficult labor and delivery. PMID:2764203
perinatal mortality in woman with structural malformation who had massive intra-ventricular haemorrhage, secondary to ruptured cerebral cavernoma. Here we have described in detail 5 patients with varied clinical manifestation causing diagnostic dilemma. They are spinal arterio-venous malformation, disseminated toxoplasmosis, massive intra-ventricular haemorrhage (ruptured cerebral cavernoma), tubercular meningitis with cortical venous thrombosis, suspected Bartter syndrome presenting as coma. Conclusion Neurological manifestation during pregnancy may not always be a primary neurological disorder, instead may be manifestation secondary to any systemic illness. Hence, a wide index of suspicion and neuroimaging aids in arriving at the diagnosis certainly improves the pregnancy outcome. PMID:28208940

Information was sought on wives of dentists or female dental assistants who underwent surgery during their pregnancies to determine the effects of anesthesia and surgery on fetal outcome. Occupational exposure to inhalation anesthetics either directly (dental assistants) or indirectly (wives of exposed male dentists) was associated with a significant increase in spontaneous abortion rate over a comparison group during both trimesters. Anesthesia for surgery was also associated with increased fetal loss when administered during the first or second trimesters. The number of congenital abormalities in children born to women who had surgery during pregnancy was not increased. For women surgically exposed to anesthetics and occupationally exposed as well, either directly or indirectly, the risk of spontaneous abortion increased almost threefold above control lvels. The authors conclude that elective surgery should be deferred during early pregnanacy to minimize potential fetal loss.

Background: Recurrent implantation failure is one of the most issues in IVF cycles. Some researchers found that beneficial effects of endometrial Scratching in women with recurrent implantation failure, while some authors demonstrated contrary results Objective: The present study aimed to investigate the effect of intrauterine. Saline infusion as a form of endometrial injury, during fresh in vitro fertilization-embryo transfer cycle, among patients with recurrent implantation failure. Materials and Methods: In this clinical trial study 63 women undergoing assisted reproductive technology were divided into two groups either local endometrial injury by intrauterine saline infusion during day 3-5 of the ongoing controlled ovarian stimulation cycle, or IVF protocol performed without any other intervention in Taleghani Hospital, Tehran, Iran. The main outcome measure was clinical pregnancy rates. Results: Patients who received intra uterine saline infusion (n=20), had significantly lower clinical pregnancy numbers (1 vs. 9, p<0.05) and implantation rates (4.7% vs. 41.6%, p<0.05), compared to controls (n=39). However, there was no significant difference in miscarriage rates (9.4% vs. 8.7%, p>0.05) and multiple pregnancy numbers (1 vs. 3, p>0.05) between groups. Conclusion: When intrauterine saline infusion as a form of endometrial injury is performed during the ongoing IVF cycles it has negative effect on reproductive outcomes among patients with recurrent implantation failure.

To determine the institutional pregnancy complications rate associated with genetic amniocentesis and ascertain whether procedural variables or pre-existing factors may determine an increased risk of having a procedural-related fetal loss, we retrospectively evaluated all the consecutive amniocentesis, with known pregnancy outcome (n = 2990), performed between January 2001 and December 2009 by two very experienced clinicians. The patients who had counselling in the same period but declined to undergo amniocentesis represent the control group (n = 487). A total of 30 fetal losses occurred within 24 weeks' gestation (1%), while in the control group, we had four losses (0.8%). Procedural variables (transplacental sample, multiple needle insertions and gestational age) were not found to be predictive of increased fetal loss rate. Previous vaginal bleeding increased the risk of pregnancy loss after amniocentesis with an OR 4.1 (95% CI 2.0-8.7); on the contrary, a history of two or more miscarriages is not associated with a greater fetal loss rate, while the increased percentage (OR 3.4, 95% CI 1.2-9.0) in patients affected by uterine myoma appears connected, after the comparison with the control group, with the presence of fibroids rather than procedure.

Chronic kidney disease complicates an increasing number of pregnancies, and at least 4% of childbearing-aged women are afflicted by this condition. Although diabetic nephropathy is the most common type of chronic kidney disease found in pregnant women, a variety of other primary and systemic kidney diseases also commonly occur. In the setting of mild maternal primary chronic kidney disease (serum creatinine <1.3 mg/dL) without poorly controlled hypertension, most pregnancies result in live births and maternal kidney function is unaffected. In cases of more moderate and severe maternal primary chronic kidney disease, the incidence of fetal prematurity, low birth weight, and death increase substantially, and the risk of accelerated irreversible decline in maternal kidney function, proteinuria, and hypertensive complications rise dramatically. In addition to kidney function, maternal hypertension and proteinuria portend negative outcomes and are important factors to consider when risk stratifying for fetal and maternal complications. In the setting of diabetic nephropathy and lupus nephropathy, other systemic disease features such as disease activity, the presence of antiphospholipid antibodies, and glycemic control play important roles in determining pregnancy outcomes. Concomitant with advances in obstetrical management and kidney disease treatments, it appears that the historically dismal maternal and fetal outcomes have greatly improved.

Teleophthalmology is gaining importance as an effective eye care delivery modality worldwide. In many developing countries, teleophthalmology is being utilized to provide quality eye care to the underserved urban population and the unserved remote rural population. Over the years, technological innovations have led to improvement in evidence and teleophthalmology has evolved from a research tool to a clinical tool. The majority of the current teleophthalmology services concentrate on patient screening and appropriate referral to experts. Specialty care using teleophthalmology services for the pediatric group includes screening as well as providing timely care for retinopathy of prematurity (ROP). Among geriatric eye diseases, specialty teleophthalmology care is focused toward screening and referral for diabetic retinopathy (DR), glaucoma, age-related macular degeneration (ARMD), and other sight-threatening conditions. Comprehensive vision screening and refractive error services are generally covered as part of most of the teleophthalmology methods. Over the past decades, outcome assessment of health care system includes patients’ assessments on their health, care, and services they receive. Outcomes, by and large, remain the ultimate validators of the effectiveness and quality of medical care. Teleophthalmology produces the same desired clinical outcome as the traditional system. Remote portals allow specialists to provide care over a larger region, thereby improving health outcomes and increasing accessibility of specialty care to a larger population. A high satisfaction level and acceptance is reported in the majority of the studies because of increased accessibility and reduced traveling cost and time. Considering the improved quality of patient care and patient satisfaction reported for these telemedicine services, this review explores how teleophthalmology helps to improve patient outcomes.

Background Violence against pregnant women is an increasing public health concern particularly in low- and middle-income countries. The purpose of this study was to measure the association between intimate partner violence (IPV) during pregnancy and the risk of adverse birth outcomes. Methods Prospective cohort study of 1276 pregnant women in Dong Anh district, Vietnam. Women with gestational age less than 24 weeks were enrolled and interviewed. Repeated interviews were performed at 30–34 weeks gestation to assess experience of IPV during pregnancy and again 48 hours post-delivery to assess the birth outcome including birth weight and gestational age at delivery. Results There was a statistically significant association between exposure to physical violence during pregnancy and preterm birth (PTB) or low birth weight (LBW). After adjustment for age, education, occupation, body mass index (BMI), haemoglobin level, previous adverse pregnancy outcomes, the pregnant women who were exposed to physical violence during pregnancy were five times more likely to have PTB (AOR = 5.5; 95%CI: 2.1–14.1) and were nearly six times more likely to give birth to a child of LBW (AOR = 5.7; 95%CI: 2.2–14.9) as compared to those who were not exposed to physical violence. Conclusion Exposure to IPV during pregnancy increases the risk of PTB and LBW. Case-finding for violence in relation to antenatal care may help protect pregnant women and improve pregnancy outcomes.

Given the detrimental influence of maternal overweight and obesity on reproductive and pregnancy outcomes for the mother and child, it is the position of the American Dietetic Association and the American Society for Nutrition that all overweight and obese women of reproductive age should receive counseling on the roles of diet and physical activity in reproductive health prior to pregnancy,during pregnancy, and in the inter conceptional period, in order to ameliorate these adverse outcomes. The effect of maternal nutritional status prior to pregnancy on reproduction and pregnancy outcomes is of great public health importance. Obesity in the United States and worldwide has grown to epidemic proportions, with an estimated 33% of US women classified as obese. This position paper has two objectives: (a) to help nutrition professionals become aware of the risks and possible complications of overweight and obesity for fertility,the course of pregnancy, birth outcomes, and short- and long-term maternal and child health outcomes;and (b) related to the commitment to research by the American Dietetic Association and the American Society for Nutrition, to identify the gaps in research to improve our knowledge of the risks and complications associated with being overweight and obese before and during pregnancy.Only with an increased knowledge of these risks and complications can health care professionals develop effective strategies that can be implemented before and during pregnancy as well as during the inter conceptional period to ameliorate adverse outcomes.
The statistics related to pregnancy and its outcomes are staggering: annually, an estimated 250000-280000 women die during childbirth. Unfortunately, a large number of women receive little or no care during or before pregnancy. At a period of critical vulnerability, interventions can be effectively delivered to improve the health of women and their newborns and also to make their pregnancy safe. This paper reviews the interventions that are most effective during preconception and pregnancy period and synergistically improve maternal and neonatal outcomes. Among pre-pregnancy interventions, family planning and advocating pregnancies at appropriate intervals; prevention and management of sexually transmitted infections including HIV; and peri-conceptual folic-acid supplementation have shown significant impact on reducing maternal and neonatal morbidity and mortality. During pregnancy, interventions including antenatal care visit model; iron and folic acid supplementation; tetanus Immunisation; prevention and management of malaria; prevention and management of HIV and PMTCT; calcium for hypertension; anti-Platelet agents (low dose aspirin) for prevention of Pre-eclampsia; anti-hypertensives for treating severe hypertension; management of pregnancy-induced hypertension/eclampsia; external cephalic version for breech presentation at term (>36 weeks); management of preterm, premature rupture of membranes; management of unintended pregnancy; and home visits for women and children across the continuum of care have shown maximum impact on reducing the burden of maternal and newborn morbidity and mortality. All of the interventions summarized in this paper have the potential to improve maternal mortality rates and also contribute to better health care practices during preconception and periconception period.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that primarily affects women during their reproductive years. The interaction between SLE and pregnancy remains debated. The objective of this study was to analyze the fetal and maternal outcomes of Chinese women with SLE. A total of 109 pregnancies in 83 SLE patients from June 2004 to June 2014 at a tertiary university hospital were reviewed retrospectively. Patients’ characteristics, clinical and laboratory data during pregnancy were obtained from electronic medical records. After exclusion of elective abortions, the live birth rate was 61.5%. Significantly, APS (antiphospholipid syndrome), disease activity, hypertension, hypocomplementemia, thrombocytopenia, and anemia during pregnancy were more commonly observed in fetal loss pregnancies than in live birth pregnancies. Compared to the 64 women with a history of SLE, 19 women with new-onset lupus during pregnancy had worse pregnancy outcome. Furthermore, the 64 patients with a history of SLE were divided into lupus nephritis group and SLE group (non-renal involvement). We found that the lupus nephritis group had worse maternal outcome than the SLE group. We conclude that new-onset lupus during pregnancy predicts both adverse maternal and fetal outcomes, while a history of lupus nephritis predicts adverse maternal outcomes. It is essential to provide SLE women with progestational counseling and regular multispecialty care during pregnancy. PMID:27442513

Porphyrias are rare metabolic diseases caused by enzymatic defects of the haeme biosynthesis. Association of pregnancy and acute porphyria is rare, but mortality rate among pregnant women from acute attack has been reported up to 42%. This paper presents a patient with pregnancy complicated by intermittent hepatic porphyria with good perinatal outcome. The pattern of the attack in pregnancy varies individually and it makes porphyric pregnancies a challenge. Previously diagnosed porphyria patients should be closely monitored during pregnancy and diagnosis of acute porphyria must be also considered in all pregnant women with unexplained abdominal pain.
Several environmental factors affect the fetus and thereby the outcome of pregnancy. Recent studies have confirmed a relation between stress and pregnancy outcome; furthermore they have indicated that biological measures of stress may predict risk of complications. Altered sex ratio may be an interesting way of measuring the effect of stress during pregnancy. Stress and work load during pregnancy seem to be related to time until conception and to becoming pregnant through assisted reproduction. Drinking large amounts of alcohol is hazardous, but drinking one drink per day appears to be safe. The effect of passive smoking continues to be a matter of debate.

Short sleep duration, poor sleep quality, and insomnia frequently characterize sleep in pregnancy during all three trimesters. We aimed: (i) to review the clinical evidence of the association between conditions of sleep loss during pregnancy and adverse pregnancy outcomes; and (ii) to discuss the potential pathophysiological mechanisms that may be involved. A systematic search of cross-sectional, longitudinal studies using Medline, Embase, and PsychINFO, and MeSH headings and key words for conditions of sleep loss such as 'insomnia', 'poor sleep quality', 'short sleep duration', and 'pregnancy outcome' was made for papers published between January 1, 1960 and July 2013. Twenty studies met inclusion criteria for sleep loss and pregnancy outcome: seven studies on prenatal depression, three on gestational diabetes, three on hypertension, pre-eclampsia/eclampsia, six on length of labor/type of delivery, eight on preterm birth, and three on birth grow/birth weight. Two main results emerged: (i) conditions of chronic sleep loss are related to adverse pregnancy outcomes; and (ii) chronic sleep loss yields a stress-related hypothalamic-pituitary-adrenal axis and abnormal immune/inflammatory, reaction, which, in turn, influences pregnancy outcome negatively. Chronic sleep loss frequently characterizes sleep throughout the course of pregnancy and may contribute to adverse pregnancy outcomes. Common pathophysiological mechanisms emerged as being related to stress system activation. We propose that in accordance to the allostatic load hypothesis, chronic sleep loss during pregnancy may also be regarded as both a result of stress and a physiological stressor per se, leading to stress 'overload'. It may account for adverse pregnancy outcomes and somatic and mental disorders in pregnancy.

Women who discover they are pregnant after exposure to a drug and pregnant women who have a condition that requires continued treatment during pregnancy are told to balance the benefits and risks of the exposure to justify continuation of treatment, discontinuation of treatment or, possibly, pregnancy termination. However, there are limited data available to inform decision-making. The Merck Pregnancy Registry Program is a company-run pregnancy registry whose objective is to acquire and analyse information on drug exposures and pregnancy outcomes to better describe the safety profile of Merck products used during pregnancy. Information is collected from women and healthcare providers who call to report drug exposure during pregnancy. Prospective pregnancies are followed up to outcome and data are collected via questionnaires, telephone calls and a review of medical records. Reports are classified as prospective (information received prior to knowledge of pregnancy outcome) or retrospective (received after the outcome is known). Congenital anomaly reports are assessed for timing of exposure, maternal age and medical history, biological plausibility and concomitant medication exposures. Rates of pregnancy outcomes and birth defects in the prospective cohort are computed and confidence intervals are calculated to reflect the strength of the finding based on the sample size. Rates of pregnancy outcomes in the Pregnancy Registry are compared with the rates of pregnancy outcomes in the general US population and, if available, in subpopulations with the relevant disease states. The limitations of post-marketing surveillance are well known as voluntary reporting of individuals and healthcare professionals is known to be subject to various types of bias. Small sample size is another major limitation. However, the strength of the registry lies in its ability to gather pregnancy outcome reports early in the life of a product and to recognise and analyse unusual birth defects

Approaches for analyzing the risks of adverse pregnancy outcomes have been the source of much debate and many publications. Much of the problem, in our view, is the conflation of time at risk with gestational age at birth (or birth weight, a proxy for gestational age). We consider the causal questions underlying such analyses with the help of a generic directed acyclic graph. We discuss competing risks and populations at risk in the context of appropriate numerators and denominators, respectively. We summarize 3 different approaches to quantifying risks with respect to gestational age, each of which addresses a distinct etiological or prognostic question (i.e., cumulative risk, prospective risk, or instantaneous risk (hazard)) and suggest the appropriate denominators for each. We show how the gestational age-specific risk of perinatal death (PND) can be decomposed as the product of the gestational age-specific risk of birth and the risk of PND conditional on birth at a given gestational age. Finally, we demonstrate how failure to consider the first of these 2 risks leads to selection bias. This selection bias creates the well-known crossover paradox, thus obviating the need to posit common causes of early birth and PND other than the study exposure.

CKD is increasingly prevalent in pregnancy. In the Torino-Cagliari Observational Study (TOCOS), we assessed whether the risk for adverse pregnancy outcomes is associated with CKD by comparing pregnancy outcomes of 504 pregnancies in women with CKD to outcomes of 836 low-risk pregnancies in women without CKD. The presence of hypertension, proteinuria (>1 g/d), systemic disease, and CKD stage (at referral) were assessed at baseline. The following outcomes were studied: cesarean section, preterm delivery, and early preterm delivery; small for gestational age (SGA); need for neonatal intensive care unit (NICU); new onset of hypertension; new onset/doubling of proteinuria; CKD stage shift; "general" combined outcome (preterm delivery, NICU, SGA); and "severe" combined outcome (early preterm delivery, NICU, SGA). The risk for adverse outcomes increased across stages (for stage 1 versus stages 4-5: "general" combined outcome, 34.1% versus 90.0%; "severe" combined outcome, 21.4% versus 80.0%; P<0.001). In women with stage 1 CKD, preterm delivery was associated with baseline hypertension (odds ratio [OR], 3.42; 95% confidence interval [95% CI], 1.87 to 6.21), systemic disease (OR, 3.13; 95% CI, 1.51 to 6.50), and proteinuria (OR, 3.69; 95% CI, 1.63 to 8.36). However, stage 1 CKD remained associated with adverse pregnancy outcomes (general combined outcome) in women without baseline hypertension, proteinuria, or systemic disease (OR, 1.88; 95% CI, 1.27 to 2.79). The risk of intrauterine death did not differ between patients and controls. Findings from this prospective study suggest a "baseline risk" for adverse pregnancy-related outcomes linked to CKD.

This narrative review discusses gestational weight gain (GWG) and medical outcomes of pregnancy, including metabolic, cardiovascular, respiratory, musculoskeletal and psychiatric systems. Taken as a whole, the available evidence shows that excessive GWG increases the risk of all medical complications of pregnancy, and negatively impacts the long-term health and weight of both mothers and their offspring. Briefly, interventions to encourage appropriate GWG are discussed and readers are directed to resources to facilitate discussion of pregnancy weight. PMID:27512468

Systemic lupus erythematosus (SLE) is mainly a disease of fertile women and the coexistence of pregnancy is by no means a rare event. How SLE and its treatment affect pregnancy outcomes is still a matter of debate. We performed a retrospective analysis of 41 SLE patients (55 pregnancies) who were followed at our university hospital from January 2000 to December 2009. The mean age of patients was 30.6±4.8 years and mean disease duration was 6.6±5.3 years. After exclusion of artificial abortions, live birth rate was 84%. Significantly, more women with stillbirth pregnancies were complicated with antiphospholipid syndrome (APS) than women with live birth pregnancies (two of eight stillbirth pregnancies (25%) versus one of 42 live birth pregnancies (2%); p=0.014) and hypocomplementemia at conception (four of eight stillbirth pregnancies (50%) versus six of 42 live birth pregnancies (14%); p=0.021). Compared with nonrenal pregnancies, renal pregnancies were younger at SLE disease onset, had a lower positivity of anti-RNP antibody, and were more complicated with pregnancy-induced hypertension. Past maximum dose of prednisolone, the dose of prednisolone at conception, and percentage of past steroid pulse therapy were higher in renal pregnancies. Outcomes of pregnancies were not significantly different both for mothers and for infants between renal and nonrenal pregnancies. We conclude that it is necessary to provide SLE mothers with the proper information before pregnancy. Women with APS or hypocomplementemia should be regarded with particular attention. Optimal management of mothers and infants requires collaborative efforts of rheumatologists and obstetricians.

Considering specific physiology changes during gestation and thinking of pregnancy as a "critical window", classification of pregnant women at early pregnancy can be considered as crucial. The paper demonstrates the use of a method based on an approach from intelligent data mining, cluster analysis. Cluster analysis method is a statistical method which makes possible to group individuals based on sets of identifying variables. The method was chosen in order to determine possibility for classification of pregnant women at early pregnancy to analyze unknown correlations between different variables so that the certain outcomes could be predicted. 222 pregnant women from two general obstetric offices' were recruited. The main orient was set on characteristics of these pregnant women: their age, pre-pregnancy body mass index (BMI) and haemoglobin value. Cluster analysis gained a 94.1% classification accuracy rate with three branch- es or groups of pregnant women showing statistically significant correlations with pregnancy outcomes. The results are showing that pregnant women both of older age and higher pre-pregnancy BMI have a significantly higher incidence of delivering baby of higher birth weight but they gain significantly less weight during pregnancy. Their babies are also longer, and these women have significantly higher probability for complications during pregnancy (gestosis) and higher probability of induced or caesarean delivery. We can conclude that the cluster analysis method can appropriately classify pregnant women at early pregnancy to predict certain outcomes.

Improved survival in thalassemia has refocused attention on quality of life, including family planning. Understanding the issues associated with infertility and adverse pregnancy outcomes may impact clinical care of patients with thalassemia. We report the number and outcomes of pregnancies among subjects enrolled in Thalassemia Clinical Research Network (TCRN) registries and examine variables associated with successful childbirth. We identified 129 pregnancies in 72 women among the 264 women, age 18 years or older in our dataset. Over 70% of pregnancies resulted in live births and 73/83 (88%) of live births occurred at full term. Most pregnancies (78.2%) were conceived without reproductive technologies. Most (59.3%) pregnancies occurred while on chronic transfusion programs, however only 38.9% were on iron chelation. Four women developed heart problems. Iron burden in women who had conceived was not significantly different from age- and diagnosis-matched controls that had never been pregnant. There was also no difference in pregnancy outcomes associated with diagnosis, transfusion status, diabetes or Hepatitis C infection. Pregnancies occurred in 27.3% of women with thalassemia of child-bearing age in the TCRN registries, a notable increase from our previous 2004 report. With optimal health maintenance, successful pregnancies may be achievable.

Using 1978 data from the Massachusetts Birth and Death Registry, examined the effects of WIC prenatal participation. Found that increased WIC participation was associated with enhanced pregnancy outcomes, but suggested that other causal factors also should be considered. (GC)
Pregnancy outcomes improved significantly over the 20th century in the United States but currently vary widely between women of different ethnic and racial backgrounds. The current health disparities that exist are based, in part, only on differences in socioeconomic status or education. There is wide variability in pregnancy outcomes within specific subgroups of women. Disparities may be due to underlying differences in health before pregnancy, differences in community norms, and individual lifestyle choices and to differences in health care delivery systems. Areas for needed research and promising new models of care are reviewed.

To explore racial-ethnic disparities in adverse pregnancy outcomes among Medicaid recipients, and to estimate excess Medicaid costs associated with the disparities. Cross-sectional study of adverse pregnancy outcomes and Medicaid payments using data from Medicaid Analytic eXtract files on all Medicaid enrollees in fourteen southern states. Compared to other racial and ethnic groups, African American women tended to be younger, more likely to have a Cesarean section, to stay longer in the hospital and to incur higher Medicaid costs. African-American women were also more likely to experience preeclampsia, placental abruption, preterm birth, small birth size for gestational age, and fetal death/stillbirth. Eliminating racial disparities in adverse pregnancy outcomes (not counting infant costs), could generate Medicaid cost savings of $114 to $214 million per year in these 14 states. Despite having the same insurance coverage and meeting the same poverty guidelines for Medicaid eligibility, African American women have a higher rate of adverse pregnancy outcomes than White or Hispanic women. Racial disparities in adverse pregnancy outcomes not only represent potentially preventable human suffering, but also avoidable economic costs. There is a significant financial return-on-investment opportunity tied to eliminating racial disparities in birth outcomes. With the Affordable Care Act expansion of Medicaid coverage for the year 2014, Medicaid could be powerful public health tool for improving pregnancy outcomes. PMID:23065298

Thromboembolic disease and obstetric complications related to ischemia of the placenta are currently the major causes of maternal mortality and morbidity. Thrombophilia been implicated in their aetiology and the magnitude of the risk depends on the type of thrombophilia. As the evidence is still unclear and controversial, questions about the clinical management of pregnant women with thrombophilia are a daily issue. We aim to review, bearing in mind the consensus and controversies, the impact of inherited thrombophilia in the risk of thrombosis related to pregnancy and of obstetric complications. Moreover, the diagnostic, preventive and therapeutic approach during pregnancy and puerperium, including the role of antithrombotic pharmacopoeia available, will be discussed.

Pregnancy is a complex period of human growth, development, and imprinting. Nutrition and metabolism play a crucial role for the health and well-being of both mother and fetus, as well as for the long-term health of the offspring. Nevertheless, several biological and physiological mechanisms related to nutritive requirements together with their transfer and utilization across the placenta are still poorly understood. In February 2009, the Child Health Foundation invited leading experts of this field to a workshop to critically review and discuss current knowledge, with the aim to highlight priorities for future research. This paper summarizes our main conclusions with regards to maternal preconceptional body mass index, gestational weight gain, placental and fetal requirements in relation to adverse pregnancy and long-term outcomes of the fetus (nutritional programming). We conclude that there is an urgent need to develop further human investigations aimed at better understanding of the basis of biochemical mechanisms and pathophysiological events related to maternal-fetal nutrition and offspring health. An improved knowledge would help to optimize nutritional recommendations for pregnancy.

Background Low- and middle-income countries (LMICs) face the highest burden of maternal and neonatal deaths. Concurrently, they have the lowest number of physicians. Innovative methods such as the exchange of health-related information using mobile devices (mHealth) may support health care workers in the provision of antenatal, delivery, and postnatal care to improve maternal and neonatal outcomes in LMICs. Objective We conducted a systematic review evaluating the effectiveness of mHealth interventions targeting health care workers to improve maternal and neonatal outcomes in LMIC. Methods The Cochrane Library, PubMed, EMBASE, Global Health Library, and Popline were searched using predetermined search and indexing terms. Quality assessment was performed using an adapted Cochrane Risk of Bias Tool. A strength, weakness, opportunity, and threat analysis was performed for each included paper. Results A total of 19 studies were included for this systematic review, 10 intervention and 9 descriptive studies. mHealth interventions were used as communication, data collection, or educational tool by health care providers primarily at the community level in the provision of antenatal, delivery, and postnatal care. Interventions were used to track pregnant women to improve antenatal and delivery care, as well as facilitate referrals. None of the studies directly assessed the effect of mHealth on maternal and neonatal mortality. Challenges of mHealth interventions to assist health care workers consisted mainly of technical problems, such as mobile network coverage, internet access, electricity access, and maintenance of mobile phones. Conclusions mHealth interventions targeting health care workers have the potential to improve maternal and neonatal health services in LMICs. However, there is a gap in the knowledge whether mHealth interventions directly affect maternal and neonatal outcomes and future research should employ experimental designs with relevant outcome measures to
Background Health care providers are often unfamiliar with the needs of women with disability. Moreover maternity and postnatal services may not be specifically tailored to the needs of women with disability and their families. We conducted a systematic review to determine the effectiveness of healthcare interventions to improve outcomes for pregnant and postnatal women with disability and for their families. Methods Studies on pregnant and postnatal women with disability and their families which evaluated the effectiveness of an intervention using a design that met the criteria used by the Cochrane Effective Practice and Organization of Care group were eligible for inclusion in this review. A comprehensive search strategy was carried using eleven electronic databases. No restriction on date or language was applied. Included studies were assessed for quality and their results summarized and tabulated. Results Only three studies fully met the inclusion criteria. All were published after 1990, and conducted as small single-centre randomized controlled trials. The studies were heterogeneous and not comparable. Therefore the main finding of this review was the lack of published research on the effectiveness of healthcare interventions to improve outcomes for pregnant women with disability and their families. Conclusions More research is required to evaluate healthcare interventions to improve outcomes for pregnant women with disability and their families. PMID:24499308

Objectives: Pregnancy in women with homozygous beta thalassaemia (HBT) carries a high risk to both the mother and fetus. The aim of this study was to investigate pregnancy outcomes among this group at a single tertiary centre. Methods: This retrospective descriptive study was conducted between January 2006 and December 2012 on all women with HBT who received prenatal care and subsequently delivered at Sultan Qaboos University Hospital, Muscat, Oman. Women who delivered elsewhere and women with the beta thalassaemia trait were excluded. Results: Ten women with HBT were studied with a total of 15 pregnancies and 14 live births. The mean maternal age ± standard deviation (SD) was 27.9 ± 3.7 years, with a range of 24–35 years. There were 14 spontaneous pregnancies and one pregnancy following hormone treatment. Eight women had been on chelation therapy before pregnancy, one of whom needed chelation during late pregnancy. Of the pregnancies, 93% had a successful outcome with a mean ± SD gestational age at delivery of 38.6 ± 0.9 weeks, with a range of 37–40 weeks. Eight babies (57%) were delivered by Caesarean section. The mean ± SD birth weight was 2.6 ± 0.2 kg, with a range of 1.9–3.0 kg. Three babies (21%) were born with low birth weights. Conclusion: Pregnancy is safe and usually has a favourable outcome in patients with HBT, provided that a multidisciplinary team is available. This is the first study of Omani patients with HBT whose pregnancies have resulted in a successful outcome. PMID:25097768

Exposure to tobacco during pregnancy is an important risk factor for infant health. Recently the prevalence of smoking during pregnancy has declined in our area. The objective of this study was to analyse the association between several social variables and the fetal exposure to smoking, as well as the association between maternal smoking and some adverse gestational outcomes. Data collection was cross-sectional. The study population were women in the city of Barcelona (Catalonia, Spain) delivering a child without birth defects. The sample corresponded to the controls of the Birth Defects Registry of Barcelona, 2% of all pregnancy deliveries in the city from 1994 to 2003 (n = 2297). Information sources were hospital records and a personal interview of mothers. The analysis measured first the association between independent variables (instruction level, social class, occupation, nationality, planned pregnancy, parity, hospital funding and smoking status of the mother's partner) with two dependent variables: smoking at the initiation of pregnancy and quitting during pregnancy. Second, the persistence of smoking over pregnancy and all independent variables were studied with three variables indicating adverse outcomes of pregnancy: low gestation, low birthweight and intrauterine growth restriction (IUGR). Finally, the joint association between the persistence of smoking over pregnancy and social class taken as independent variables was determined with the three variables indicating adverse outcomes of pregnancy. Logistic regression models were fitted, adjusting for maternal age. Results are presented as odds ratios with their 95% confidence intervals. The prevalence of smoking at the onset of gestation was 41%, and 40% of these women quit during pregnancy, so that 25% delivered as active smokers. Fewer women with higher educational levels and from families with non-manual jobs smoked, as did immigrants, those planning pregnancy and women whose partner did not smoke

Abstract Background: Despite prior efforts to develop pregnancy risk prediction models, there remains a lack of evidence to guide implementation in clinical practice. The current aim was to develop and validate a risk tool grounded in social determinants theory for use among at-risk Medicaid patients. Methods: This was a retrospective cohort study of 409 women across 17 Cincinnati health centers between September 2013 and April 2014. The primary outcomes included preterm birth, low birth weight, intrauterine fetal demise, and neonatal death. After random allocation into derivation and validation samples, a multivariable model was developed, and a risk scoring system was assessed and validated using area under the receiver operating characteristic curve (AUROC) values. Results: The derived multivariable model (n=263) included: prior preterm birth, interpregnancy interval, late prenatal care, comorbid conditions, history of childhood abuse, substance use, tobacco use, body mass index, race, twin gestation, and short cervical length. Using a weighted risk score, each additional point was associated with an odds ratio of 1.57 for adverse outcomes, p<0.001, AUROC=0.79. In the validation sample (n=146), each additional point conferred an odds ratio of 1.20, p=0.03, AUROC=0.63. Using a cutoff of 20% probability for the outcome, sensitivity was 29%, with specificity 82%. Positive and negative predictive values were 22% and 85%, respectively. Conclusions: Risk scoring based on social determinants can discriminate pregnancy risk within a Medicaid population; however, performance is modest and consistent with prior prediction models. Future research is needed to evaluate whether implementation of risk scoring in Medicaid prenatal care programs improves clinical outcomes. PMID:26102375

Rubella is a mild viral disease that typically occurs in childhood. Rubella infection during pregnancy causes congenital rubella syndrome, including the classic triad of cataracts, cardiac abnormalities and sensorineural deafness. Highly effective vaccines have been developed since 1969, and vaccination campaigns have been established in many countries. Although there has been progress, the prevention and diagnosis of rubella remain problematic. This article reviews the implications and management of rubella during pregnancy.

This article is a review of the literature assessing pregnancy outcomes and the effect of metformin treatment among women with polycystic ovary syndrome (PCOS). A review of research published in English was undertaken using PubMed and MEDLINE databases. The weight of the available evidence suggests that pregnant women with PCOS are at an increased risk of developing gestational diabetes, hypertensive disorders of pregnancy, preterm birth and early pregnancy loss. Obesity is a contributory factor for the increased risk of gestational diabetes in this group of women and is estimated to affect 5-40% of pregnant women with PCOS. The prevalence of other obstetric complications is estimated at 10-30% for gestational hypertension, 8-15% for pre-eclampsia and 6-15% for preterm birth. The association between PCOS and early pregnancy loss may not be direct, wherein the presence of PCOS-associated hyperinsulinemia, leading to hyperandrogenemia, has been implicated in the pathophysiology of early pregnancy loss. Apart from the role of metformin in improving the metabolic consequences accompanying PCOS, it has been shown to improve pregnancy rates in women with PCOS who are resistant to clomiphene citrate. In conclusion, pregnancy in women with PCOS is associated with adverse obstetric outcomes (multiple adverse obstetric risk). Whether metformin should be administered throughout pregnancy still remains controversial. Further prospective studies that foster a larger number of participants and adjust for all potentially confounding factors are needed.

Overweight and obesity pre pregnancy or during pregnancy is associated with an increased risk for maternal obstetric and fetal complications. Diet is one modifiable risk factor that women may be motivated to improve. General healthy eating guidelines, micronutrient sufficiency and macronutrient quantity and quality are important nutrition considerations pre and during pregnancy. With regards to specific nutrients, health authorities have recommendations for folate and/or iodine supplementation; but not consistently for iron and omega-3 despite evidence for their association with health outcomes. There are modest additional requirements for energy and protein, but not fat or carbohydrate, in mid-late pregnancy. Diet indices and dietary pattern analysis are additional tools or methodologies used to assess diet quality. These tools have been used to determine dietary intakes and patterns and their association with pregnancy complications and birth outcomes pre or during pregnancy. Women who may unnecessarily resist foods due to fear of food contamination from listeriosis and methylmercury may limit their diet quality and a balanced approached is required. Dietary intake may also vary according to certain population characteristics. Additional support for women who are younger, less educated, overweight and obese, from socially disadvantaged areas, smokers and those who unnecessarily avoid healthy foods, is required to achieve a higher quality diet and optimal lifestyle peri conception.

The aim of the study was to investigate the etiology and pregnancy outcomes in mothers with polyhydramnios through prenatal diagnosis and pregnancy outcome analysis of pregnant women with polyhydramnios. One hundred and thirty women were enrolled. Fifty pregnant women with polyhydramnios were categorized as the case group, and 80 pregnant women with normal amniotic fluid were categorized as the control group. The causes of polyhydramnios and the pregnancy outcomes were analyzed. Two cases had chromosomal abnormalities, seven had severe α-thalassemia, 15 had fetal anomalies, four had maternal-fetal diseases and 22 had unexplained idiopathic polyhydramnios. Significantly, higher occurrences of cesarean section, preterm birth, fetal anomaly, fetal distress, fetal macrosomia and female fetuses occurred in patients with polyhydramnios than in patients without polyhydramnios. Polyhydramnios is associated with a higher occurrence of adverse perinatal outcomes. Intensive monitoring of the maternal-fetal condition and prenatal diagnosis is important in patients with polyhydramnios.

Neurocysticercosis (NCC) is a parasitic infection with the larvae of Taenia solium from contaminated pork. It is a leading cause of seizures in the developing world. Symptoms may be secondary to live or degenerating cysts, or previous infection causing calcification or gliosis. Diagnosis is based on clinical presentation, radiological confirmation of intracranial lesions and immunological testing. Management involves symptom control with antiepileptics and antiparasitic agents. Few cases have been described of maternal NCC during pregnancy. We describe a 25-year-old female presenting to a London hospital with secondary generalized seizures. MRI of the brain confirmed a calcified lesion in the right parietal lobe, and she gave a corroborative history of NCC during her childhood in India. She was stabilized initially on antiepileptics, but during her pregnancy presented with breakthrough seizures and radiological evidence of NCC reactivation. She was managed symptomatically with antiepileptics and completed the pregnancy to term with no fetal complications. PMID:27471595

Introduction: Regarding to the recent advances in assisted reproductive techniques (ART), twin and multiple pregnancies have increased during past years. Objective: This study was performed to compare obstetrics and perinatal outcomes of dichorionic twin pregnancy following ART with spontaneous pregnancy. Materials and Methods: In this cross-sectional study which was performed in Ghaem Hospital, Mashhad University of Medical Sciences, 107 dichorionic twin pregnancy were enrolled in two groups: spontaneous group (n=96) and ART group (n=31). Basic criteria and obstetrics and neonatal outcomes information including demographic data, gestational age, mode of delivery, pregnancy complications (preeclampsia, gestational diabetes, preterm labor, and intrauterine growth retardation (IUGR), postpartum hemorrhage), neonatal outcomes (weight, first and fifth minute Apgar score, Neonatal Intensive Care Unit (NICU) admission, mortality, respiratory distress, and icterus) were recorded using a questionnaire. Results: Preterm labor, gestational diabetes, and preeclampsia were significantly higher in ART group compared to spontaneous pregnancy group. However, other factors such as anemia, IUGR, postpartum hemorrhage, and intrauterine fetal death (IUFD) were not significantly different between groups. There were no significant differences between groups in terms of neonatal outcomes (weight, 1st and 5th min Apgar score <7, NICU hospitalization, mortality, respiratory distress, and icterus). Conclusion: With regard of significantly higher poor outcomes such as preeclampsia, gestational diabetes and preterm labor in ART group, the couples should be aware of these potential risks before choosing ART.

Prune belly syndrome is a rare congenital syndrome that primarily affects male fetuses. Affected men are universally infertile; however, there is a paucity of information published on the reproductive potential of affected women. Pregnancy outcomes in affected women have not been described in the literature. We describe the case of pregnancy in an affected woman. Her pregnancy progressed without complication. Her fetus had no stigmata of the syndrome. Her labour and delivery were, however, complicated by a prolonged second stage of labour and need for vacuum-assisted vaginal delivery.
Background Diabetes in pregnancy carries an increased risk of adverse pregnancy outcomes for both the mother and foetus, but it also provides an excellent early opportunity for intervention in the life course for both mother and baby. In the context of the escalating epidemic of chronic diseases among Indigenous Australians, it is vital that this risk is reduced as early as possible in the life course of the individual. The aims of the PANDORA Study are to: (i) accurately assess rates of diabetes in pregnancy in the Northern Territory (NT) of Australia, where 38% of babies are born to Indigenous mothers; (ii) assess demographic, clinical, biochemical, anthropometric, socioeconomic and early life development factors that may contribute to key maternal and neonatal birth outcomes associated with diabetes in pregnancy; and (iii) monitor relevant post-partum clinical outcomes for both the mothers and their babies. Methods/Design Eligible participants are all NT women with diabetes in pregnancy aged 16 years and over. Information collected includes: standard antenatal clinical information, diagnosis and management of diabetes in pregnancy, socio-economic status, standard clinical birth information (delivery, gestational age, birth weight, adverse antenatal and birth outcomes). Cord blood is collected at the time of delivery and detailed neonatal anthropometric measurements performed within 72 hours of birth. Information will also be collected regarding maternal post-partum glucose tolerance and cardio-metabolic risk factor status, breastfeeding and growth of the baby up to 2 years post-partum in the first instance. Discussion This study will accurately document rates and outcomes of diabetes in pregnancy in the NT of Australia, including the high-risk Indigenous Australian population. The results of this study should contribute to policy and clinical guidelines with the goal of reducing the future risk of obesity and diabetes in both mothers and their offspring. PMID

Screening and treatment of sexually transmitted infections (STIs) in pregnancy represents an overlooked opportunity to improve the health outcomes of women and infants worldwide. Although Chlamydia trachomatis is the most common treatable bacterial STI, few countries have routine pregnancy screening and treatment programs. We reviewed the current literature surrounding Chlamydia trachomatis in pregnancy, particularly focusing on countries in sub-Saharan Africa and Asia. We discuss possible chlamydial adverse pregnancy and infant health outcomes (miscarriage, stillbirth, ectopic pregnancy, preterm birth, neonatal conjunctivitis, neonatal pneumonia, and other potential effects including HIV perinatal transmission) and review studies of chlamydial screening and treatment in pregnancy, while simultaneously highlighting research from resource-limited countries in sub-Saharan Africa and Asia.

Outcome of pregnancy was reported by 99 patients who were cured of childhood Wilms' tumor at seven pediatric cancer centers during 1931 to 1979. These patients carried or sired 191 singleton pregnancies of at least 20 weeks in duration. Among the 114 pregnancies in women who had received abdominal radiotherapy for Wilms' tumor, an adverse outcome occurred in 34 (30%). There were 17 perinatal deaths (five in premature low-birth-weight infants) and 17 other low-birth-weight infants. Compared with white women in the United States, the irradiated women had an increased perinatal mortality rate (relative risk, 7.9) and an excess of low-birth-weight infants (relative risk, 4.0). In contrast, an adverse outcome was found in two (3%) of the 77 pregnancies in nonirradiated female patients with Wilms' tumor and wives of male patients. The high risk of adverse pregnancy outcome should be considered in the counseling and prenatal care of women who have received abdominal radiotherapy for Wilms' tumor.
Young people leaving out-of-home care are overrepresented among teenage parents. This paper examines the research literature and identifies key factors that contribute to early pregnancy and parenthood for care leavers, the challenges of early parenting and the positive effects of early parenting. The implications for out-of-home care policy and…
Background Cranberry is one of the most commonly used herbs during pregnancy. The herb has been used traditionally against urinary tract infections. No studies are found that specifically address the risk of malformations after use of cranberry during pregnancy. The aim of the study was to investigate the safety of cranberry use during pregnancy, including any effects on congenital malformations and selected pregnancy outcomes. Methods The study is based on data from The Norwegian Mother and Child Cohort Study including more than 100,000 pregnancies from 1999 to 2008. Information on use of cranberry and socio-demographic factors was retrieved from three self-administered questionnaires completed by the women in pregnancy weeks 17 and 30, and 6 months after birth. Information on pregnancy outcomes was retrieved from the Medical Birth Registry of Norway. Results Among the 68,522 women in the study, 919 (1.3%) women had used cranberry while pregnant. We did not detect any increased risk of congenital malformations after use of cranberry. Furthermore, the use of cranberry was also not associated with increased risk for stillbirth/neonatal death, low birth weight, small for gestational age, preterm birth, low Apgar score (<7), neonatal infections or maternal vaginal bleeding in early pregnancy. Although an association was found between use of cranberry in late pregnancy and vaginal bleeding after pregnancy week 17, further sub-analyses of more severe bleeding outcomes did not support a significant risk. Conclusions The findings of this study, revealing no increased risk of malformations nor any of the following pregnancy outcomes; stillbirth/neonatal death, preterm delivery, low birth weight, small for gestational age, low Apgar score and neonatal infections are reassuring. However, maternal vaginal bleeding should be investigated further before any firm conclusion can be drawn. Treatment guidelines on asymptomatic bacteriuria in pregnancy recommend antimicrobial

Single-twin demise can pose substantial risks for the surviving co-twin, including increased risk of fetal loss, preterm delivery, neurovascular injury, and end-organ damage. In this chapter, we summarise recently published research on the causes of single twin demise, the pathophysiology of injury to the surviving co-twin, and the evidence for current management strategies. The gestation at which single intrauterine fetal demise occurs, and the chorionicity of the multiple pregnancies, are the two most important factors when considering the risks to the surviving twin. Management should include fortnightly ultrasound scans for growth, umbilical artery Doppler studies, and liquor volume. In monochorionic twins, more complex Doppler assessment with middle cerebral artery Doppler velocimetry and a magnetic resonance imaging of the survivor's brain at least 3 weeks after single intrauterine fetal demise occurs should be carried out to look for evidence of neurological morbidity. With no other obstetric complications, dichorionic pregnancies can be delivered at term. Monochorionic pregnancies are more difficult to manage, and are often delivered between 34 and 36 weeks.

Introduction Chorangiomas (CAs) are the most common non-trophoblastic tumor-like-lesions of the placenta. Although the clinical significance of small CAs is unknown, the large lesions are often associated with maternal and fetal complications. The aim of our study was to assess the maternal clinical characteristics and neonatal outcome in singleton and multiple pregnancies with placental CA. Materials and Methods Among 15742 selected placentas 170 CAs were diagnosed. Pregnancy and neonatal outcomes were analyzed in singleton (n = 121) and multiple (n = 49) pregnancy groups including 121 and 100 neonates, respectively. Results The frequency of APGAR score <7 at 5 minutes (p = 0,012), abnormal pulsatility index (p = 0,034), and abnormal blood flow class (p = 0,011) were significantly higher in neonates from singleton compared to multiple pregnancies. Significantly smaller CAs in singleton pregnancies were related to small for gestational age neonates (p = 0,00040) and neonates admitted to the neonatal care unit (p = 0,028). In singleton pregnancies, significantly smaller CAs were associated to maternal preeclampsia (p = 0,039) and larger CAs to multiparity (p = 0,005) and smoking (p = 0,001) groups. The frequency of preeclampsia was high in both singleton and multiple pregnancy groups (41,32% vs 26,53%, respectively), however, the difference did not reach the level of statistical significance. Discussion A high incidence of preeclampsia in cohort of placental CA might lead to a possible recognition of CAs as potential morphologic indicator of placental hypoxia. Conclusion A more favorable pregnancy outcome in multiple gestations compared to the singleton gestations with CAs might reflect an adaptive mechanism for increased demand of oxygen and associated placental tissue hypoxia in this group.

The present work evaluated the benefit of a novel shipping and maturation medium (SMM) not requiring a CO2 gas for maturation and subsequent embryonic development of slaughterhouse and ovum pickup (OPU) bovine cumulus-oocyte complexes (COCs). Four experiments were conducted. In experiment 1, COCs were maturated for 18 hours in SMM and then incubated for 6 hours in, or 24 hours in a conventional system (control). Experiment 2 compared maturation for 24 hours in SMM versus 24 hours in the control. Experiment 3 compared three different incubation temperatures (37 °C, 38 °C, and 38.5 °C) for COCs maturation in SMM. In experiment 4, COCs obtained from 166 OPU sessions (representing two dairy and two beef breeds) in two locations (Wisconsin and California) were matured in SMM or control and evaluated relative to embryo production and pregnancy rates. Frozen semen was used for all experiments. The results for experiment 1 showed that the blastocyst rate and total embryo production rate (TE, Day-7 morulae plus all blastocysts) were higher for SMM than those in the control. However, no differences were observed for cleavage rate or blastocyst stage. In experiment 2, the blastocyst rate and TE were higher for SMM than those in the control; however, there was no difference for cleavage rate, total cell number, blastocyst stage. In experiment 3, the cleavage rate was similar, but the blastocyst rate and TE were greater for 38.5 °C than those for 38.0 °C and 37.5 °C. For experiment 4, Wisconsin OPU-derived COCs had a greater cleavage rate, blastocyst rate, TE, and blastocyst stage for SMM versus control. There were no breed effects. For the California trial, OPU-derived COCs matured in SMM had similar cleavage and pregnancy rates at Day 35 but greater blastocyst rates and transferred embryos per session than the control, which resulted in 2.2 more pregnancies per OPU session. Holstein COCs had superior embryonic development but similar pregnancy compared with Jersey. We

Experimental evidence indicates that the primary maternal environmental factor that regulates feto-placental growth is substrate delivery to the placental site, which is the product of maternal substrate levels and the rate of placental-bed blood flow. Thus, maternal factors which change either substrate level or flow alter feto-placental growth rate. The best-studied substrate in human pregnancy is glucose, and there is a direct relationship between maternal blood glucose levels and size at birth. Altering the type of carbohydrate eaten (high- v. low-glycaemic sources) changes postprandial glucose and insulin responses in both pregnant and non-pregnant women, and a consistent change in the type of carbohydrate eaten during pregnancy influences both the rate of feto-placental growth and maternal weight gain. Eating primarily high-glycaemic carbohydrate results in feto-placental overgrowth and excessive maternal weight gain, while intake of low-glycaemic carbohydrate produces infants with birth weights between the 25th and the 50th percentile and normal maternal weight gain. The calculated difference in energy retention with similar total energy intakes is of the order of 80,000 kJ. Preliminary information from subsequent metabolic studies indicates that the mechanisms involved include changes in: daily digestible energy requirements (i.e. metabolic efficiency), substrate utilization (glucose oxidation v. lipid oxidation), and insulin resistance and sensitivity. Thus, altering the source of maternal dietary carbohydrate may prove to be a valuable tool in the management of pregnancies at risk for anomalous feto-placental growth and for the prevention and/or treatment of obesity and insulin resistance in the non-pregnant state.

Objectives The aim of this study was to evaluate the effects of non-surgical treatment of periodontal disease during the second trimester of gestation on adverse pregnancy outcomes. Material and Methods Pregnant patients during the 1st and 2nd trimesters at antenatal care in a Public Health Center were divided into 2 groups: NIG – "no intervention" (n=17) or IG- "intervention" (n=16). IG patients were submitted to a non-surgical periodontal treatment performed by a single periodontist consisting of scaling and root planning (SRP), professional prophylaxis (PROPH) and oral hygiene instruction (OHI). NIG received PROPH and OHI during pregnancy and were referred for treatment after delivery. Periodontal evaluation was performed by a single trained examiner, blinded to periodontal treatment, according to probing depth (PD), clinical attachment level (CAL), plaque index (PI) and sulcular bleeding index (SBI) at baseline and 35 gestational weeks-28 days post-partum. Primary adverse pregnancy outcomes were preterm birth (<37 weeks), low birth weight (<2.5 kg), late abortion (14-24 weeks) or abortion (<14 weeks). The results obtained were statistically evaluated according to OR, unpaired t test and paired t test at 5% significance level. Results No significant differences were observed between groups at baseline examination. Periodontal treatment resulted in stabilization of CAL and PI (p>0.05) at IG and worsening of all periodontal parameters at NIG (p<0.0001), except for PI. Significant differences in periodontal conditions of IG and NIG were observed at 2nd examination (p<0.001). The rate of adverse pregnancy outcomes was 47.05% in NIG and 6.25% in IG. Periodontal treatment during pregnancy was associated to a decreased risk of developing adverse pregnancy outcomes [OR=13.50; CI: 1.47-123.45; p=0.02]. Conclusions Periodontal treatment during the second trimester of gestation contributes to decrease adverse pregnancy outcomes. PMID:21552714

This retrospective study was conducted to determine the pregnancy outcomes and identify predictive factors of adverse outcomes in pregnant migrant workers who delivered at Songklanagarind Hospital from January 2002 to December 2012. Two hundred and forty migrant worker pregnancies were enrolled. Pre-eclampsia, gestational diabetes mellitus, pre-term birth and foetal intrauterine growth restriction found were 15, 7.9, 13.7 and 3.7%, respectively. No stillbirth was found. Apgar score was = 7 at 1 and 5 min and neonatal intensive care unit admission was found to be 12.1, 4.2 and 11.3%, respectively. Antenatal care place, low haemoglobin level and the presence of maternal underlying disease were significantly related to increased risk of overall adverse maternal outcomes. Only pre-term birth was significantly related to overall adverse neonatal outcomes.

Data from animal studies show that maternal stress is associated with disturbances in pregnancy outcomes and offspring development and behavior, possibly as a result of permanent structural and functional changes termed "early-life programming." There is growing interest in whether similar relationships are present in humans. Here we review recent significant findings from the literature on the impact of prenatal psychologic stressors on pregnancy outcome and offspring development, with a particular focus on the developing brain. Relevant papers were searched using PubMed, and reference lists from obtained articles were checked. In humans, prenatal stress is associated with pregnancy complications, developmental, cognitive, and behavioral disorders, and possible onset of psychopathology in later life. In contrast to the available research done in animals, virtually nothing is known about the effects of prenatal stress on morphologic fetal brain development, and the mechanisms underlying subsequent associated behavioral changes.

The progress in research of in vitro fertilization and fetal-maternal medicine allows more women and men, with fertility problems due to cystic fibrosis, to have a baby. In the majority of cases, pregnancy in women with cystic fibrosis results in favorable maternal and fetal outcomes. However, the incidence of preterm delivery, intrauterine growth restriction, caesarean section and deterioration of the maternal health are increased. Pre-pregnancy counseling is a crucial component of overall obstetric care, especially in women with poor pulmonary function. Additionally, closer monitoring during pregnancy with a multidisciplinary approach is required. The value of serial ultrasound scans and fetal Doppler assessment is important for the control of maternal and fetal wellbeing, as well as for the definition of the appropriate timing of delivery. In this article, clinical issues of pregnant women with cystic fibrosis are reviewed; counseling, obstetrical management and perinatal outcomes are being discussed.

Objective The objective is to estimate the impact of maternal weight gain outside the 2009 Institute of Medicine recommendations on perinatal outcomes in twin pregnancies. Study Design Twin pregnancies with two live births between January 1, 2004 and December 31, 2014 delivered after 23 weeks Finger Lakes Region Perinatal Data System (FLRPDS) and Central New York Region Perinatal Data System were included. Women were classified into three groups using pre-pregnancy body mass index (BMI). Perinatal outcomes in women with low or excessive weekly maternal weight gain were assessed using normal weekly weight gain as the referent in each BMI group. Results Low weight gain increased the risk of preterm delivery, birth weight less than the 10th percentile for one or both twins and decreased risk of macrosomia across all BMI groups. There was a decreased risk of hypertensive disorders in women with normal pre-pregnancy weight and an increased risk of gestational diabetes with low weight gain in obese women. Excessive weight gain increased the risk of hypertensive disorders and macrosomia across all BMI groups and decreased the risk of birth weight less than 10th percentile one twin in normal pre-pregnancy BMI group. Conclusion Among twin pregnancies, low weight gain is associated with low birth weight and preterm delivery in all BMI groups and increased risk of gestational diabetes in obese women. Our study did not reveal any benefit from excessive weekly weight gain with potential harm of an increase in risk of hypertensive disorders of pregnancy. Normal weight gain per 2009 IOM guidelines should be encouraged to improve pregnancy outcome in all pre-pregnancy BMI groups.

Objective To verify whether body mass index (BMI) classification proposed by the Institute of Medicine (IOM) is valid in Japanese women. Method A study was conducted in 97,157 women with singleton pregnancies registered in the Japan Society of Obstetrics and Gynecology (JSOG) Successive Pregnancy Birth Registry System between January 2013 and December 2013, to examine pregnancy outcomes in four groups stratified by pre-pregnancy BMI category according to the 2009 criteria recommended by the Institute of Medicine (IOM). The groups comprised 17,724 underweight women with BMI <18.5, 69,126 normal weight women with BMI 18.5–24.9, 7,502 overweight women with BMI 25–29.9, and 2,805 obese women with BMI ≥30. The pregnancy outcomes were also compared among subgroups stratified by a gestational weight gain below, within, and above the optimal weight gain. Results The higher the pre-pregnancy BMI, the higher the incidences of pregnancy-induced hypertension, gestational diabetes mellitus, macrosomia, cesarean delivery, postpartum hemorrhage, and post-term birth, but the lower the incidence of small for gestational age (SGA). In all pre-pregnancy BMI category groups, excess gestational weight gain was associated with a higher frequency of large for gestational age and macrosomia; poor weight gain correlated with a higher frequency of SGA, preterm birth, preterm premature rupture of membranes, and spontaneous preterm birth; and optimal weight gain within the recommended range was associated with a better outcome. Conclusion The BMI classification by the IOM was demonstrated to be valid in Japanese women. PMID:27280958

Peripartum cardiomyopathy (PPCM) is a rare condition with a diverse spectrum of potential outcomes, ranging from frequent complete recovery to fulminant heart failure and death. The pathogenesis of PPCM is not well understood, and relatively little is known about its incidence and prevalence. PPCM is often under-recognised in the clinical setting. Early investigation and diagnosis with subsequent expert management may improve outcomes. The development of registries will allow this condition to be better characterised and may help answer crucial questions regarding its optimal medical and surgical management. This paper reviews the potential approaches to improve outcomes in patients with PPCM.

Bacterial invasion in subgingival sites especially of gram-negative organisms are initiators for periodontal diseases. The periodontal pathogens with persistent inflammation lead to destruction of periodontium. In recent years, periodontal diseases have been associated with a number of systemic diseases such as rheumatoid arthritis, cardiovascular-disease, diabetes mellitus, chronic respiratory diseases and adverse pregnancy outcomes including pre-term low-birth weight (PLBW) and pre-eclampsia. The factors like low socio-economic status, mother's age, race, multiple births, tobacco and drug-abuse may be found to increase risk of adverse pregnancy outcome. However, the same are less correlated with PLBW cases. Even the invasion of both aerobic and anerobic may lead to inflammation of gastrointestinal tract and vagina hence contributing to PLBW. The biological mechanism involved between PLBW and Maternal periodontitis is the translocation of chemical mediators of inflammation. Pre-eclampsia is one of the commonest cause of both maternal and fetal morbidity as it is characterized by hypertension and hyperprotenuria. Improving periodontal health before or during pregnancy may prevent or reduce the occurrences of these adverse pregnancy outcomes and, therefore, reduce the maternal and perinatal morbidity and mortality. Hence, this article is an attempt to review the relationship between periodontal condition and altered pregnancy outcome. PMID:26229389

It is the position of the Academy of Nutrition and Dietetics that all women of reproductive age receive education about maternal and fetal risks associated with prepregnancy obesity, excessive gestational weight gain, and significant postpartum weight retention, including potential benefits of lifestyle changes. Behavioral counseling to improve dietary intake and physical activity should be provided to overweight and obese women, beginning in the preconception period and continuing throughout pregnancy, for at least 12 to 18 months postpartum. Weight loss before pregnancy may improve fertility and reduce the risk of poor maternal-fetal outcomes, such as preterm birth, gestational diabetes, gestational hypertension, pre-eclampsia, assisted delivery, and select congenital anomalies. Lifestyle interventions that moderate gestational weight gain may reduce the risk of poor pregnancy outcomes, such as gestational diabetes, gestational hypertension, large for gestational age, and macrosomia, as well as lower the risk for significant postpartum retention. Postpartum interventions that promote healthy diet and physical activity behaviors may reduce postpartum weight retention and decrease obesity-related risks in subsequent pregnancies. Analysis of the evidence suggests that there is good evidence to support the role of diet, physical activity, and behavior changes in promoting optimal weight gain during pregnancy; however, there is currently a relative lack of evidence in other areas related to reproductive outcomes.

The purpose of this study was to investigate the relationship of selected characteristics of the paternal work environment and occupational history to the incidence of complications in pregnancy, complications in labor and anomalies in birth outcomes. The literature suggested that male exposure to teratogenic hazards in the form of radiation and chemical compounds, primarily in the form of solvents, has been implicated in reproductive disorders and malformed offspring in animals. Similarly, some recent research suggests that the exposure of male workers to such hazards on their job may have consequences for their spouses and children. Based on these experimental research studies and analyses of persons working in high risk occupations, a broader study of the potential contribution of paternal work environment variables to the success of pregnancy and birth outcomes seemed warranted. Based upon the literature review, a model was proposed for predicting complications in pregnancy, complications in labor and birth outcome (normal birth, low birth weight, congenital malformations and fetal death). From the 1980 National Natality Survey and the 1980 National Fetal Mortality Survey, four sub-samples of married couples, with both husband and wife employed, were selected on the basis of one of the four birth outcomes. The model called for controlling a range of maternal intrinsic and extrinsic health and behavioral variables known to be related to birth outcomes. Multiple logistic regression procedures were used to analyze the effects of father's exposure to radiation and solvents on the job, to complications in pregnancy and labor, and to birth outcome, while controlling for maternal variables. The results indicated that none of the paternal variables were predictors of complications in labor. Further, there was no clear pattern of results, though father's degree of exposure to solvents, and exposures to radiation did reach significance in some analyses.

Objective To compare the incidences of preterm delivery, cervical incompetence treated by cerclage, placental implantation or retention problems (ie, placenta praevia, placental abruption and retained placenta) and postpartum haemorrhage between women with and without a history of pregnancy termination. Design A retrospective cohort study using aggregated data from a national perinatal registry. Setting All midwifery practices and hospitals in the Netherlands. Participants All pregnant women with a singleton pregnancy without congenital malformations and a gestational age of ≥20 weeks who delivered between January 2000 and December 2007. Main outcome measures Preterm delivery, cervical incompetence treated by cerclage, placenta praevia, placental abruption, retained placenta and postpartum haemorrhage. Results A previous pregnancy termination was reported in 16 000 (1.2%) deliveries. The vast majority of these (90–95%) were performed by surgical methods. The incidence of all outcome measures was significantly higher in women with a history of pregnancy termination. Adjusted ORs (95% CI) for cervical incompetence treated by cerclage, preterm delivery, placental implantation or retention problems and postpartum haemorrhage were 4.6 (2.9 to 7.2), 1.11 (1.02 to 1.20), 1.42 (1.29 to 1.55) and 1.16 (1.08 to 1.25), respectively. Associated numbers needed to harm were 1000, 167, 111 and 111, respectively. For any listed adverse outcome, the number needed to harm was 63. Conclusions In this large nationwide cohort study, we found a positive association between surgical termination of pregnancy and subsequent preterm delivery, cervical incompetence treated by cerclage, placental implantation or retention problems and postpartum haemorrhage in a subsequent pregnancy. Absolute risks for these outcomes, however, remain small. Medicinal termination might be considered first whenever there is a choice between both methods. PMID:23793655

Abstract Objective. To clarify the clinical significance of antiphospholipid antibody (aPL) profile in patients with obstetric antiphospholipid syndrome (APS). Methods. Clinical records of 13 pregnant patients (15 pregnancies) with obstetrical APS were reviewed over 10 years. Patients who met the Sapporo Criteria fully were studied, whereas those with only early pregnancy loss were excluded. In addition to classical aPL: lupus anticoagulant (LA), anticardiolipin antibody (aCL), and anti-β2-glycoprotein I (aβ2GPI); phosphatidylserine-dependent anti-prothrombin antibody (aPS/PT) and kininogen-dependent anti-phosphatidylethanolamine antibody (aPE) were also examined in each case. Results. Cases were divided into two groups according to patient response to standard treatment: good and poor outcome groups. All cases with poor outcome presented LA, with IgG aβ2GPI and IgG aPS/PT were also frequently observed. IgG aPE did not correlate with pregnancy outcome. Conclusion. aPL profile may predict pregnancy outcome in patients with this subset of obstetric APS.

The American public consumes a wide array of caffeinated products as coffee, tea, chocolate, cola beverages, and caffeine-containing medication. Therefore, it seems of value to inform both the scientific community and the consumer about the potential effects of excessive caffeine consumption, particularly by pregnant women. The results of this literature review suggest that heavy caffeine use (> or = 300 mg per day) during pregnancy is associated with small reductions in infant birth weight that may be especially detrimental to premature or low-birth-weight infants. Some researchers also document an increased risk of spontaneous abortion associated with caffeine consumption prior to and during pregnancy. However, overwhelming evidence indicates that caffeine is not a human teratogen, and that caffeine appears to have no effect on preterm labor and delivery. More research is needed before unambiguous statements about the effects of caffeine on pregnancy outcome variables can be made.
Care for the emotional state of pregnant women remains a neglected aspect of obstetric medicine. Many prospective studies have shown that, if a mother is depressed, anxious, or stressed while pregnant, this increases the risk for her child having a wide range of adverse outcomes, including emotional problems, symptoms of attention deficit hyperactivity disorder, or impaired cognitive development. Although genetics and postnatal care clearly affect these outcomes, evidence for an additional prenatal causal component is substantial. Prenatal anxiety or depression may contribute 10-15% of the attributable load for emotional and behavioural outcomes. The Nurse Family Partnership remains the only intervention that starts in pregnancy and has been shown to have long-term benefits for the behaviour of the child. Several other interventions, however, are likely to be helpful. Depression, anxiety, and stress during pregnancy are frequently undetected by health professionals, and untreated. Programmes to help with this should eventually improve child outcome.

Atrazine (ATR) is a commonly used agricultural herbicide that has been the subject of epidemiologic studies assessing its relation to reproductive health problems. This review evaluates both the consistency and the quality of epidemiologic evidence testing the hypothesis that ATR exposure, at usually encountered levels, is a risk factor for birth defects, small for gestational age birth weight, prematurity, miscarriages, and problems of fetal growth and development. We followed the current methodological guidelines for systematic reviews by using two independent researchers to identify, retrieve, and evaluate the relevant epidemiologic literature on the relation of ATR to various adverse outcomes of birth and pregnancy. Each eligible paper was summarized with respect to its methods and results with particular attention to study design and exposure assessment, which have been cited as the main areas of weakness in ATR research. As a quantitative meta-analysis was not feasible, the study results were categorized qualitatively as positive, null, or mixed. The literature on ATR and pregnancy-related health outcomes is growing rapidly, but the quality of the data is poor with most papers using aggregate rather than individual-level information. Without good quality data, the results are difficult to assess; however, it is worth noting that none of the outcome categories demonstrated consistent positive associations across studies. Considering the poor quality of the data and the lack of robust findings across studies, conclusions about a causal link between ATR and adverse pregnancy outcomes are not warranted. PMID:24797711

Background. Bacterial vaginosis (BV) is a complex clinical syndrome characterized by alterations in the normal vaginal flora and a malodorous discharge when symptomatic. In pregnancy, BV has been associated with adverse outcomes such as miscarriage, premature rupture of membranes, preterm birth, and low birth weight. This study was conducted to determine the prevalence and associations of BV and pregnancy outcomes among pregnant women in Lagos University Teaching Hospital (LUTH). Methods. We conducted a prospective observational study with high vaginal swabs obtained from consecutive newly registered antenatal women between 14 and 36 weeks gestation. The women were monitored until delivery, and their pregnancy outcome and demographic data were obtained using an interviewer-administered questionnaire. Results. Bacterial vaginosis was diagnosed by Nugent score in 64 of 246 women, giving a prevalence rate of 26%. Bacterial vaginosis was significantly associated with preterm delivery (risk ratio [RR], 2.68; 95% confidence interval [CI], 1.44–4.98), low birth weight (RR, 3.20; 95% CI, 1.29–7.94), and premature rupture of membranes (RR, 6.75; 95% CI, 3.11–14.67). The association between BV and miscarriage (<28 weeks gestation) and neonatal admission for various morbidities was not statistically significant. Conclusions. The prevalence rate of BV among pregnant women in LUTH is high and is significantly associated with adverse pregnancy outcome. Routine screening and treatment of women preconceptually may enable interventions to prevent these adverse outcomes. PMID:26989754

Care coordination services that link pregnant women to health-promoting resources, avoid duplication of effort, and improve communication between families and providers have been endorsed as a strategy for reducing disparities in adverse pregnancy outcomes, however empirical evidence regarding the effects of these services is contradictory and incomplete. This study investigates the effects of maternity care coordination (MCC) on pregnancy outcomes in North Carolina. Birth certificate and Medicaid claims data were analyzed for 7,124 women delivering live infants in North Carolina from October 2008 through September 2010, of whom 2,255 received MCC services. Propensity-weighted analyses were conducted to reduce the influence of selection bias in evaluating program participation. Sensitivity analyses compared these results to conventional ordinary least squares analyses. The unadjusted preterm birth rate was lower among women who received MCC services (7.0 % compared to 8.3 % among controls). Propensity-weighted analyses demonstrated that women receiving services had a 1.8 % point reduction in preterm birth risk; p < 0.05). MCC services were also associated with lower pregnancy weight gain (p = 0.10). No effects of MCC were seen for birthweight. These findings suggest that coordination of care in pregnancy can significantly reduce the risk of preterm delivery among Medicaid-enrolled women. Further research evaluating specific components of care coordination services and their effects on preterm birth risk among racial/ethnic and geographic subgroups of Medicaid enrolled mothers could inform efforts to reduce disparities in pregnancy outcome.

This study aimed to examine the risk of adverse pregnancy outcomes in children born to mothers who redeemed a prescription for systemic or topical acyclovir during pregnancy. Data on prescriptions of acyclovir were obtained from the Danish North Jutland Prescription Database and data on pregnancy outcomes from the Danish Medical Birth Registry and the County Hospital Discharge Registry. The risk of malformations, low birth weight, preterm birth and stillbirth in users of acyclovir were compared with non-exposed women using a follow-up design, while the risk of spontaneous abortion was examined using a case-control design. 90 pregnant women had redeemed a prescription for systemic acyclovir, and 995 women for topical acyclovir, during 30 d before conception, or during their pregnancies from 1 January 1990 to 31 December 2001. The odds ratios (95% confidence intervals) of the exposed relative to the non-exposed for the systemic and topical acyclovir were: malformations, 0.69 (0.17-2.82) and 0.84 (0.51, 1.39); low birth weight, 2.03 (0.50-8.35) and 0.48 (0.21-1.07); preterm birth, 1.04 (0.38-2.85) and 0.95 (0.70-1.28); stillbirth (for topical acyclovir), 1.70 (0.80-3.60); and spontaneous abortion, 2.16 (0.60-7.80) and 1.29 (0.80-3.60). There is increasing evidence that the use of systemic acyclovir is not associated with an increased prevalence of malformations at birth and preterm delivery. The data for low birth weight and spontaneous abortion are still inconclusive, although the risk of spontaneous abortion is increased in women exposed to acyclovir during the first month of pregnancy. The use of topical acyclovir does not seem to be associated with any adverse pregnancy outcome, although data on stillbirth are inconclusive.

The incidence of multiple pregnancies has increased dramatically over the last few years in developed countries, largely attributed to delayed childbearing and the increasing use of assisted reproduction technologies and ovulation inducing hormones. Relatively few countries have population-based statistics covering birth statistics. Of those that do, the numbers of quintuplet pregnancies rose sharply in the nineties while, at the same time, their delivery rates decreased greatly because of the use of fetal reduction. Fetal reduction is not possible or legal in some countries, Poland being one of them, and therefore obstetricians are faced with the challenges of quintuplet deliveries. Conservative treatment and management is difficult, and outcomes often vary greatly. Despite this, expert care provided at tertiary care centers can positively influence outcomes. The objective of this article is to present different care options and their consequences in two illustrative cases, as well as to establish a set of obstetric care and management goals that would allow prolongation of the gestation time. Quintuplet pregnancy is rare but poses relevant clinical problems to both the obstetrician and the neonatologist. It should be managed with close cooperation between all concerned. Due to the extreme and invariable risk of premature delivery associated with quintuplet pregnancies, we recommend early diagnosis, adequate prenatal care at one tertiary medical center, routine hospitalization and bed rest, repeated ante partum ultrasound surveillance with tests of fetal well-being, tocolytic therapy at first signs of the risk of premature labor, and specialized neonatology care after delivery.

Reviews find a likely adverse effect of air pollution on perinatal outcomes, but variation of findings hinders the ability to incorporate the research into policy. The International Collaboration on Air Pollution and Pregnancy Outcomes (ICAPPO) was formed to better understand relationships between air pollution and adverse birth outcomes through standardized parallel analyses in datasets from different countries. A planning group with 10 members from 6 countries was formed to coordinate the project. Collaboration participants have datasets with air pollution values and birth outcomes. Eighteen research groups with data for approximately 20 locations in Asia, Australia, Europe, North America, and South America are participating, with most participating in an initial pilot study. Datasets generally cover the 1990s. Number of births is generally in the hundreds of thousands, but ranges from around 1,000 to about one million. Almost all participants have some measure of particulate matter, and most have ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. Strong enthusiasm for participating and a geographically-diverse range of participants should lead to understanding uncertainties about the role of air pollution in perinatal outcomes and provide decision-makers with better tools to account for pregnancy outcomes in air pollution policies.

The objective of the study was to analyze possible adverse effects of peripartum cocaine use on maternal and fetal outcomes. Informed consent was given by 720 (97%) of 740 women who delivered consecutively at a large urban public hospital to test an umbilical cord blood sample for the presence of non-medically administered drugs of abuse and alcohol and to be interviewed for the study. Samples were tested for the presence of a cocaine metabolite (benzoylecgonine-BZE) by radioimmunoassay. The presence of other substances of abuse (alcohol, methamphetamine, opiates) resulted in exclusion from the sample of 143 subjects. Thus, in this cohort analysis, drug-free controls (N = 469) were compared to those positive for cocaine only (N = 108). Peripartum exposure to cocaine only, and no other substances of abuse, was associated with an increased frequency of abruptio placentae (1.9% vs 0% for control, P < 0.004), thick meconium stained amniotic fluid (3.9% vs 0.7% for controls, P < 0.006), premature rupture of membranes (P < 0.02), genitourinary anomalies (OR = 3.6, P < 0.05), abdominal wall defects (OR = 4.4, P < 0.01) and increased frequency of low birth weight (OR = 2.0, P < 0.02). These are important findings because previous studies have been complicated by the confounding effects of other substances of abuse. Am. J. Hum. Biol. 11:598-602, 1999.

Detecting patterns of maternal drinking that place fetuses at risk for fetal alcohol spectrum disorders (FASDs) is critical to diagnosis, treatment, and prevention but is challenging because information on antenatal drinking collected during pregnancy is often insufficient or lacking. Although retrospective assessments have been considered less favored by many researchers due to presumed poor reliability, this perception may be inaccurate because of reduced maternal denial and/or distortion. The present study hypothesized that fetal alcohol exposure, as assessed retrospectively during child adolescence, would be related significantly to prior measures of maternal drinking and would predict alcohol-related behavioral problems in teens better than antenatal measures of maternal alcohol consumption. Drinking was assessed during pregnancy, and retrospectively about the same pregnancy, at a 14-year follow-up in 288 African-American women using well-validated semistructured interviews. Regression analysis examined the predictive validity of both drinking assessments on pregnancy outcomes and on teacher-reported teen behavior outcomes. Retrospective maternal self-reported drinking assessed 14 years postpartum was significantly higher than antenatal reports of consumption. Retrospective report identified 10.8 times more women as risk drinkers (≥ one drink per day) than the antenatal report. Antenatal and retrospective reports were moderately correlated and both were correlated with the Michigan Alcoholism Screening Test. Self-reported alcohol consumption during pregnancy based on retrospective report identified significantly more teens exposed prenatally to at-risk alcohol levels than antenatal, in-pregnancy reports. Retrospective report predicted more teen behavior problems (e.g., attention problems and externalizing behaviors) than the antenatal report. Antenatal report predicted younger gestational age at birth and retrospective report predicted smaller birth size

Objective In the present study, we aimed to evaluate the effects of high doses of dexamethasone (DEX) in early pregnancy on pregnancy outcomes. Methods Pregnant BALB/c mice were treated with high-dose DEX in the experimental group or saline in the control group on gestational days (GDs) 0.5 to 4.5. Pregnant mice were sacrificed on GDs 7.5, 13.5, or 18.5 and their peripheral blood, placentas, fetuses, and uterine tissue were collected. Decidual and placenta cell supernatants were examined to evaluate the effect of DEX on the proliferation of mononuclear cells, the quantity of uterine macrophages and uterine natural killer (uNK) cells, and levels of progesterone and 17β-estradiol, as determined by an 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide assay, immunohistochemistry, and enzyme-linked immunosorbent assay, respectively. We also were measured fetal and placental growth parameters on GD 18.5. Results We found that high doses of DEX were associated with an increased abortion rate, enhancement of the immunosuppressive effect of the decidua, alterations in placental growth parameters, decreased progesterone and 17β-estradiol levels, and a reduced frequency of macrophages and uNK cells. Conclusion Our data suggest that the high-dose administration of DEX during early pregnancy negatively affected pregnancy outcomes. PMID:27104153

OBJECTIVE To compare pregnancy outcomes by completed week of gestation after 39 weeks with outcomes at 39 weeks. STUDY DESIGN Secondary analysis of a multicenter trial of fetal pulse oximetry in spontaneously laboring or induced nulliparous women ≥36 weeks’ gestation. Maternal outcomes included a composite (treated uterine atony, blood transfusion and peripartum infections) and cesarean delivery. Neonatal outcomes included a composite of death, neonatal respiratory and other morbidities and neonatal ICU admission. RESULTS Among the 4086 women studied, the risks of the composite maternal outcome (p-value for trend<0.001), cesarean delivery (p<0.001) and composite neonatal outcome (p=0.047) increased with increasing gestational age from 39 to ≥41 completed weeks. Adjusted odds ratios (95% CI) for 40 and ≥41 weeks respectively compared with 39 weeks were 1.29 (1.03–1.64) and 2.05 (1.60–2.64) for composite maternal outcome, 1.28 (1.05–1.57) and 1.75 (1.41–2.16) for cesarean delivery and 1.25 (0.86–1.83) and 1.37 (0.90–2.09) for composite neonatal outcome. CONCLUSIONS Risks of maternal morbidity and cesarean delivery but not neonatal morbidity increased significantly beyond 39 weeks. PMID:22244471
Indigenous women in Latin America have poorer reproductive health outcomes than the general population and face considerable barriers in accessing adequate health services. Indigenous women have high rates of adolescent fertility and unintended pregnancy and may face increased risks for morbidity and mortality related to unsafe abortion. However, research among this population, particularly focusing on social and cultural implications of unwanted pregnancy and unsafe abortion, is significantly limited. This article reviews the literature on unsafe abortion in Latin America and describes successful interventions to ameliorate reproductive health outcomes within Indigenous communities. It also explores important implications for future research. Shedding light on the circumstances, perspectives, and lived realities of Indigenous women of childbearing age, could encourage further qualitative investigation and mitigate negative outcomes through improved understanding of the topic, targeted culturally appropriate interventions, and recommendations for future policy and programming reformations.

Most pregnant women with epilepsy require antiepileptic drug (AED) therapy. Present guidelines recommend optimizing treatment prior to conception, choosing the most effective AED for seizure type and syndrome, using monotherapy and lowest effective dose, and supplementing with folate. The Epilepsy Therapy Project established the international Health Outcomes in Pregnancy and Epilepsy (HOPE) forum to learn more about the impact of AEDs on the developing fetus, particularly the role of pregnancy registries in studying AED teratogenicity. The primary outcome of interest in these registries is the occurrence of major congenital malformations, with some data collected on minor malformations. Cognitive and behavioral outcomes are often beyond the timeframe for follow-up of these registries and require independent study. The HOPE consensus report describes the current state of knowledge and the limitations to interpretations of information from the various sources. Data regarding specific risks for both older and newer AEDs need to be analyzed carefully, considering study designs and confounding factors. There is a critical need for investigations to delineate the underlying mechanisms and explain the variance seen in outcomes across AEDs and within a single AED.

We analyzed interview and record review data from 9,823 deliveries to evaluate the relationship between prior history of induced abortion and subsequent late pregnancy outcomes. Complications such as bleeding in the first and third trimesters, abnormal presentations and premature rupture of the membranes, abruptio placentae, fetal distress, low birth weight, short gestation, and major malformations occurred more often among women with a history of two or more induced abortions. A logistic regression analysis to control for multiple confounding factors showed that a history of one induced abortion was statistically significantly associated with first-trimester bleeding but with no other untoward pregnancy events, and a history of two or more induced abortions was statistically associated with first-trimester bleeding, abnormal presentations, and premature rupture of the membranes. While these relationships merit further research, the results of this study are largely reassuring. A history of one or more prior induced abortions does not appear to increase substantially the risk of adverse late outcomes of subsequent pregnancies.

Maternal immunity undergoes subtle adjustment in order to tolerate the semi-allogeneic embryo and maintain the host defense against potential pathogens. Concomitantly, coagulation systems change from an anti-coagulant state to a pro-coagulant state to meet the hemostatic challenge of placentation and delivery. Innate immunity and blood coagulation systems are the first line of defense to protect a host against exogenous challenges, including alloantigens and mechanical insults, and preserve the integrity of an organism. The interactions between coagulation and immune systems have been extensively studied. Immune cells play a pivotal role in the initiation of the coagulation cascade, whereas coagulation proteases display substantial immuno-modulatory effects. Upon exogenous challenges, the immune and coagulation systems are capable of potentiating each other leading to a vicious cycle. Natural killer (NK) cells, macrophages (Mphis) and dendritic cells (DCs) are three major innate immune cells that have been demonstrated to play essential roles in early pregnancy. However, immune maladaptation and hemostatic imbalance have been suggested to be responsible for adverse pregnant outcomes, such as preeclampsia (PE), miscarriage, recurrent spontaneous abortion (RSA) and intrauterine growth restriction (IUGR). In this review, we will summarize the mutual regulation between blood coagulation and innate immune systems as well as their roles in the maintenance of normal pregnancy and in the pathogenesis of adverse pregnancy outcomes.

Evaluate homelessness during pregnancy as a unique, time-dependent risk factor for adverse birth outcomes. 9,995 mothers of children <48 months old surveyed at emergency departments and primary care clinics in five US cities. Mothers were classified as either homeless during pregnancy with the index child, homeless only after the index child's birth, or consistently housed. Outcomes included birth weight as a continuous variable, as well as categorical outcomes of low birth weight (LBW; <2,500 g) and preterm delivery (<37 weeks). Multiple logistic regression and adjusted linear regression analyses were performed, comparing prenatal and postnatal homelessness with the referent group of consistently housed mothers, controlling for maternal demographic characteristics, smoking, and child age at interview. Prenatal homelessness was associated with higher adjusted odds of LBW (AOR 1.43, 95 % CI 1.14, 1.80, p < 0.01) and preterm delivery (AOR 1.24, 95 % CI 0.98, 1.56, p = 0.08), and a 53 g lower adjusted mean birth weight (p = 0.08). Postnatal homelessness was not associated with these outcomes. Prenatal homelessness is an independent risk factor for LBW, rather than merely a marker of adverse maternal and social characteristics associated with homelessness. Targeted interventions to provide housing and health care to homeless women during pregnancy may result in improved birth outcomes.

Renal disease management organizations have reported achieving significant decreases in mortality and hospitalization in conjunction with cost savings, improved patient satisfaction and quality of life. Disease management organizations strive to fill existing gaps in care delivery through the standardized use of risk assessment, predictive modeling, evidence based guidelines and process and outcomes measurement. Patient self-management education and the provision of individual nurse care managers are also key program components. As we more fully measure clinical outcomes and total health-care costs including payments from all insurance and government entities, pharmacy costs and out-of-pocket expenditures, the full implications of disease management can be better defined. The results of this analysis will have a profound influence on United States healthcare policy. At present, current data suggests that the promise of disease management, improved care at reduced cost, can and is being realized in ESRD.

Nearly 90% of women in the United States have taken medications during pregnancy. Medication exposures during pregnancy can result in adverse pregnancy and neonatal outcomes including birth defects, fetal loss, intrauterine growth restriction, prematurity, and longer-term neurodevelopmental outcomes. Advising pregnant women about the safety of medication use during pregnancy is complicated by a lack of data necessary to engage the woman in an informed discussion. Routinely, health care providers turn to the package insert, yet this information can be incomplete and can be based entirely on animal studies. Often, adequate safety data are not available. In a busy clinical setting, health care providers need to be able to quickly locate the most up-to-date information in order to counsel pregnant women concerned about medication exposure. Deciding where to locate the best available information is difficult, particularly when the needed information does not exist. Pregnancy registries are initiated to obtain more data about the safety of specific medication exposures during pregnancy; however, these studies are slow to produce meaningful information, and when they do, the information may not be readily available in a published form. Health care providers have valuable data in their everyday practice that can expand the knowledge base about medication safety during pregnancy. This review aims to discuss the limitations of the package insert regarding medication safety during pregnancy, highlight additional resources available to health care providers to inform practice, and communicate the importance of pregnancy registries for expanding knowledge about medication safety during pregnancy.

Objective Antipsychotic medications are used by increasing numbers of women of reproductive age. The safety of these medications during pregnancy has not been well-described. We undertook a systematic review and meta-analysis of the adverse obstetric and neonatal outcomes associated with exposure to antipsychotics during pregnancy. Data Sources PubMed, Reprotox, and ClinicalTrials.gov were searched to identify potential studies for inclusion. Methods of Study Selection Case-control or cohort studies estimating adverse birth outcomes associated with antipsychotic exposure during pregnancy were included. Pooled odds ratios (OR) were used for dichotomous outcomes and weighted mean differences (WMD) were used for infant birth weight and gestational age. Thirteen cohort studies, including 6,289 antipsychotic-exposed and 1,618,039 unexposed pregnancies were included. Tabulation, Integration, and Results Antipsychotic exposure was associated with an increased risk of major malformations (Absolute Risk Difference = 0.03, 95% confidence interval [CI] 0.00 – 0.05, p=0.04, Z = 2.06), heart defects (Absolute Risk Difference =0.01, 95% CI 0.00 – 0.01, p<0.001, Z = 3.44), preterm delivery (Absolute Risk Difference = 0.05, 95% CI 0.03 – 0.08, p<0.001, Z = 4.10), small-for-gestational-age births (Absolute Risk Difference = 0.05, 95% CI 0.02 – 0.09, p = 0.006, Z = 2.74), elective termination (Absolute Risk Difference = 0.09, 95% CI 0.05 – 0.13, p<0.001, Z = 4.69) and decreased birth weight (WMD=−57.89g, 95%CI −103.69g – −12.10g, p=0.01). There was no significant difference in the risk of major malformations (test for subgroup differences: χ2 = 0.07, df = 1, p = 0.79) between typical (OR = 1.55, 95% CI 1.21 – 1.99, p = 0.006) and atypical (OR = 1.39, 95% CI 0.66 – 2.93, p = 0.38) antipsychotic medications. Antipsychotic exposure was not associated with risk of large for gestational age births, stillbirth, and spontaneous abortion. Although antipsychotic

We previously reported that hypergravity exposure affects food intake and mass gain during pregnancy. In the present study, we explored the hypothesis that changes in maternal body mass in hypergravity-exposed pregnant rat dams affect pregnancy outcome and early offspring development. Furthermore, we hypothesized that the changes observed at 1.5G will be magnified at higher gravity and by exposure during critical developmental periods. To test this hypothesis, we compared maternal body mass gain, food consumption, birth outcome and early offspring development between Sprague Dawley rat dams exposed to graded (1.5 1.75G) chronic hypergravity (HG) or rotation (rotational control, RC) on a 24-ft centrifuge for 22.5 h starting on gestational day (G) 10 with dams housed under identical conditions but not exposed to hypergravity (SC). We also compared maternal body mass, food consumption, birth outcome and early offspring development between rat dams exposed to 1.65G during different stages of pregnancy and nursing. Exposure to hypergravity resulted in transient loss in body mass and prolonged decrease in food consumption in HG dams, but the changes observed at 1.5G were not magnified at 1.65G or 1.75G. On the other hand RC dams gained more mass and consumed more food than SC dams. Exposure to hypergravity also affected pregnancy outcome as evidenced by decreased litter size, lowered neonatal mass at birth, and higher neonatal mortality; pregnancy outcome was not affected in RC dams. Neonatal changes evidenced by impaired righting response observed at 1.5G was magnified at higher gravity and was dependent on the period of hypergravity exposure. On the other hand, righting response was improved in RC neonates. Hypergravity exposure during early postpartum affected the food consumption of nursing mothers and affected early survival of their offspring. The changes observed in dams and neonates appear to be due to hypergravity exposure since animals exposed to the rotation

The mouth is an obvious portal of entry to the body, and oral health reflects and influences general health and well being. Maternal oral health has significant implications for birth outcomes and infant oral health. Maternal periodontal disease, that is, a chronic infection of the gingiva and supporting tooth structures, has been associated with preterm birth, development of preeclampsia, and delivery of a small-for-gestational age infant. Maternal oral flora is transmitted to the newborn infant, and increased cariogenic flora in the mother predisposes the infant to the development of caries. It is intriguing to consider preconception, pregnancy, or intrapartum treatment of oral health conditions as a mechanism to improve women's oral and general health, pregnancy outcomes, and their children's dental health. However, given the relationship between oral health and general health, oral health care should be a goal in its own right for all individuals. Regardless of the potential for improved oral health to improve pregnancy outcomes, public policies that support comprehensive dental services for vulnerable women of childbearing age should be expanded so that their own oral and general health is safeguarded and their children's risk of caries is reduced. Oral health promotion should include education of women and their health care providers ways to prevent oral disease from occurring, and referral for dental services when disease is present.

Background: Cardiac operations in pregnant patients are a challenge for physicians in multidisciplinary teams due to the complexity of the condition which affects both mother and baby. Management strategies vary on a case-by-case basis. Feto-neonatal and maternal outcomes after cardiopulmonary bypass (CPB) in pregnancy, especially long-term follow-up results, have not been sufficiently described. Methods: This review was based on a complete literature retrieval of articles published between 1991 and April 30, 2013. Results: Indications for CPB during pregnancy were cardiac surgery in 150 (96.8 %) patients, most of which consisted of valve replacements for mitral and/or aortic valve disorders, resuscitation due to amniotic fluid embolism, autotransfusion, and circulatory support during cesarean section to improve patient survival in 5 (3.2 %) patients. During CPB, fetuses showed either a brief heart rate drop with natural recovery after surgery or, in most cases, fetal heart rate remained normal throughout the whole course of CPB. Overall feto-neonatal mortality was 18.6 %. In comparison with pregnant patients whose baby survived, feto-neonatal death occurred after a significantly shorter gestational period at the time of onset of cardiac symptoms, cardiac surgery/resuscitation under CPB in the whole patient setting, or cardiac surgery/resuscitation with CPB prior to delivery. Conclusions: The most common surgical indications for CPB during pregnancy were cardiac surgery, followed by resuscitation for cardiopulmonary collapse. CPB was used most frequently in maternal cardiac surgery/resuscitation in the second trimester. Improved CPB conditions including high flow, high pressure and normothermia or mild hypothermia during pregnancy have benefited maternal and feto-neonatal outcomes. A shorter gestational period and the use of CPB during pregnancy were closely associated with feto-neonatal mortality. It is therefore important to attempt delivery ahead of

To review flight regulations and gestational complications associated with air travel in pregnant passengers, flight attendants, and aviators. A literature search was undertaken on the relationship of air travel and spontaneous pregnancy losses, intrauterine fetal demise (IUFD), birth weight<10th percentile, preterm delivery, and neonatal intensive care unit admissions. The literature search identified 128 abstracts, of which 9 evaluated air travel and pregnancy outcomes. The risk of a pregnancy loss (spontaneous abortion or IUFD) was greater in flight attendants than controls (odds ratio [OR]: 1.62, 95% confidence interval [CI]: 1.29, 2.04). The risk of preterm birth<37 weeks was greater in passengers than controls (OR: 1.44, 95% CI: 1.07, 1.93). However, the risk of preeclampsia (OR: 0.86, 95% CI: 0.58, 1.27), neonatal intensive care unit admissions (OR: 1.19, 95% CI: 0.78, 1.82), or birth weight<10th percentile (OR: 1.25, 95% CI: 0.62, 2.48) was not increased. Flight attendants did not have an increased risk of preterm birth compared to controls (OR: 1.37, 95% CI: 0.85, 2.22) or delivering infants with birth weight<10th percentile (OR: 1.57, 95% CI: 0.68, 3.74). The risks of spontaneous abortions and other adverse pregnancy outcomes have been poorly studied in a limited number of investigations. An analysis of the available information suggests a greater risk of spontaneous abortions or IUFD in flight attendants, and a greater risk of preterm birth<37 weeks in air passengers. However, the literature on which these findings are based is generally not of high methodologic quality.

Prevention and treatment of sexually transmitted infections (STIs) in the sexually active population are the main steps to prevent perinatal infection. However, the spread of STIs continues at an astronomical pace despite various attempts at controlling the epidemic. An important reason for this lack of STI control is that a large percentage of infected people go untreated because they have asymptomatic or unrecognized infections. The microbial differential diagnosis of STIs implicated in adverse pregnancy outcome is broad and includes viral, bacterial and protozoal infections. Infertility, ectopic pregnancy, pelvic inflammatory disease, chorioamnionitis, premature rupture of membranes, preterm birth and puerperal sepsis are some of complications seen in women as a result of infection with sexually transmitted pathogens. In addition, STIs may facilitate the acquisition and transmission of HIV. In the fetus or neonate, complications include abnormalities of the major organ systems. Infections in the form of pneumonia or conjunctivitis may also occur. Due to the lack of simple, inexpensive and sensitive point-of-care tests, screening for STIs in pregnancy is not performed routinely.

Maternal folate and vitamin B12 deficiency predict poor pregnancy outcome. To improve pregnancy outcomes in rural area of China, we investigate rural women’s folic acid supplementation (FAS) status and the associations between maternal vitamin B status during the first trimester and subsequent adverse pregnancy outcomes. We collected the questionnaire information and drew 5 ml of blood from 309 early pregnant rural women. The birth outcomes were retrieved from medical records after delivery. Out of the total, 257 had taken FAS, including 50 before conception (group A) and 207 during the first trimester (group B). The concentration of plasma folate and the RBC folate supplementation groups were obviously higher than that of no-supplementation group (group N, p<0.01). The mean vitamin B12 levels in FAS group were significantly higher than those in groups N and B (p<0.05). Women who delivered SGA or premature infants had reduced plasma folate levels (p<0.05) compared with controls. The multiple linear regression models revealed that RBC folate levels affected the infant birth weight (p<0.01) and birth length (p<0.05). In conclusion, FAS can significantly improve plasma folate and RBC folate levels in childbearing-age women and reduce the risk of subsequent adverse pregnancy outcomes. PMID:28366994

While the effect of HIV infection on some maternal outcomes is well established, for some others there is conflicting information on possible association with HIV. In this study we investigated pregnancy and neonatal outcome of HIV positive women in large HIV treatment centre over a period of 84 months. They were managed according to the Nigerian PMTCT protocol. Adverse obstetric and neonatal outcome were observed in 48.3% HIV positives compared 30.3% to the negatives (OR: 2.08; CI: 1.84-2.34). Low birth weight ( OR:2.95; CI:1.95-3.1), preterm delivery (OR:2.05; CI:1.3-3.1), perinatal death (OR:1.9;CI:1.3-3.2), and spontaneous abortion (OR:1.37; CI:1.1-2.3) were factors found to be independently associated with HIV. Low CD4 count (OR: 2.45; CI: 1.34- 4.56) and opportunistic infections (OR: 2.11; CI: 1.56-3.45) were to be associated with adverse obstetric and neonatal outcome. This study confirms the association of HIV, severe immunosuppression and opportunistic infection and adverse obstetric and neonatal outcome.

It is known that substance use is associated with increased risk of adverse pregnancy, outcomes. The aims of this study were to estimate the prevalence of alcohol, cigarette, betel quid and drug use during pregnancy and to assess the risk of adverse effects of betel quid chewing on pregnancy outcomes in aboriginal women in southern Taiwan. The study population included 62 women with adverse pregnancy outcomes and 124 age-matched women. Subjects were interviewed at their homes by trained interviewers using a structure questionnaire. Prevalences of various substance use in aborigines with adverse pregnancy outcomes were estimated as follows: alcohol, 43.6%; smoking, 14.5%; betel quid chewing, 43.6% and over-the-counter drug use, 8.1%; whereas in the comparison group it was alcohol, 38.7%; smoking, 8.1%; betel quid chewing, 28.2% and none used drugs. Univariate analysis revealed that adverse pregnancy outcomes were associated with maternal betel quid chewing, maternal illness during pregnancy, and the number of pregnancies (gravidity) experienced. After adjusting for maternal illness and number of previous pregnancies covariates, the prevalence of adverse pregnancy outcome was computed to be 2.8-fold higher among betel quid chewing women as compared to non-chewers (AOR=2.8, 95% CI=1.2-6.8). Among the aboriginal women, prenatal care is essential not only for routine care, but also to focus health education on the harmful effects of substance use, especially betel quid use during pregnancy.

Previous studies have demonstrated the influence of changes in the age at which women give birth, and of developments in prenatal screening and diagnosis on the number of pregnancies diagnosed and terminated with chromosomal anomalies. However, we are unaware of any population studies examining pregnancy terminations after diagnosis of chromosomal anomalies that has included all aneuploidies and the influence of maternal factors. The aims of this study were to examine the association between results of prenatal tests and pregnancy termination, and the proportion of foetuses with and without chromosomal anomalies referred for invasive diagnostic tests over time. Diagnostic information of 26,261 prenatal invasive tests from all genetic service laboratories in Scotland from 2000 to 2011 was linked to Scottish Morbidity Records to obtain details on pregnancy outcome. Binary logistic regression was carried out to test the associations of year and type of diagnosis with pregnancy termination, while controlling for maternal age, neighbourhood deprivation and parity. There were 24,155 (92.0%) with no chromosomal anomalies, 1,483 (5.6%) aneuploidy diagnoses, and 623 (2.4%) diagnoses of anomaly that was not aneuploidy (including translocations and single chromosome deletions). In comparison with negative test results, pregnancies diagnosed with trisomy were most likely to be terminated (adjusted OR 437.40, 95% CI 348.19–549.46) followed by other aneuploid anomalies (adjusted OR 95.94, 95% CI 69.21–133.01). During the study period, fewer pregnancies that were diagnosed with aneuploidy were terminated, including trisomy diagnoses (adjusted OR 0.44, 95% CI 0.26–0.73). Older women were less likely to terminate (OR 0.35, 95% CI 0.28, 0.42), and parity was also an independent predictor of termination. In keeping with previous findings, while the number of invasive diagnostic tests declined, the proportion of abnormal results increased from 6.09% to 10.88%. Systematic

The use of low-dose aspirin and heparinoids has improved the pregnancy outcome in obstetric antiphospholipid syndrome (APS). However, current treatment fails in 20-30% of APS pregnancies, raising the need to explore other treatments to improve obstetrical outcome. Hydroxychloroquine (HCQ) is widely used in patients with autoimmune diseases, mainly systemic lupus erythematous (SLE), due to its anti-inflammatory, anti-aggregant and immune-regulatory properties. Evidence from in vitro and animal models suggests a potential protective effect of HCQ in obstetric APS. Pending the availability of prospective trials, we aimed to systematically review the available evidence and to assess the clinical judgment of a panel of experts regarding the use of HCQ in improving pregnancy outcome in women with antiphospholipid antibodies (aPL). Clinical data on the ability of HCQ to improve pregnancy outcome in women with aPL are very limited in the available literature. Only one cohort study evaluating maternal and fetal outcome of pregnancy in patients with SLE who were exposed to HCQ was identified. Four of 14 (29%) treated with HCQ patients had pregnancy failure, compared with six of 24 (25%) of patients not treated with HCQ. However, the effect of HCQ was not adjusted for the use of other medications such as aspirin, heparins or steroids. Selected experts were contacted by e-mail and asked to review the summary of the evidence provided by the working group and to briefly answer each of the proposed questions. Overall, the panel of experts agreed that adding HCQ could be considered in selected cases or after failure of standard treatment with aspirin and a heparin agent. Specifically, the majority of experts considered adding HCQ in specific scenarios, such as women with previous thrombosis (either arterial and/or venous), and/or with previous ischaemic placenta-mediated complications. Prospective studies are necessary before the use of HCQ during pregnancy in women with a

Objective: To evaluate effects of G-CSF on a cancelled ART cycle due to thin endometrium. Materials and methods: In a nonrandomized clinical trial from January 2011 to January 2013 in two tertiary university based hospitals fifteen patients undergoing embryo transfer and with the history of cycle cancellation due to thin endometrium were studied. Intrauterine infusion of G-CSF was done on the day of oocyte pick-up or 5 days before embryo transfer. The primary outcome to be measured was an endometrium thickened to at least 6 mm and the secondary outcome was clinical pregnancy rate and consequently take-home baby. All previous cycles were considered as control for each patient. Results: The G-CSF was infused at the day of oocyte retrieval or 5 days before embryo transfer. The endometrial thickness reached from 3.593±0.251 mm to 7.120 ± 0.84 mm. The mean age, gravidity, parity, and FSH were 35.13± 9.531 years, 3, 1 and 32.78 ± 31.10 mIU/ml, respectively. The clinical pregnancy rate was 20%, and there was one missed abortion, a mother death at 34 weeks, and a preterm labor at 30 weeks due to PROM. Conclusion: G-CSF may increase endometrial thickness in the small group of patients who had no choice except cycle cancellation or surrogacy. PMID:26622308

It is the position of the Academy of Nutrition and Dietetics that women of childbearing age should adopt a lifestyle optimizing health and reducing risk of birth defects, suboptimal fetal development, and chronic health problems in both mother and child. Components leading to a healthy pregnancy outcome include healthy prepregnancy weight, appropriate weight gain and physical activity during pregnancy, consumption of a wide variety of foods, appropriate vitamin and mineral supplementation, avoidance of alcohol and other harmful substances, and safe food handling. Pregnancy is a critical period during which maternal nutrition and lifestyle choices are major influences on mother and child health. Inadequate levels of key nutrients during crucial periods of fetal development may lead to reprogramming within fetal tissues, predisposing the infant to chronic conditions in later life. Improving the well-being of mothers, infants, and children is key to the health of the next generation. This position paper and the accompanying practice paper (www.eatright.org/members/practicepapers) on the same topic provide registered dietitian nutritionists and dietetic technicians, registered; other professional associations; government agencies; industry; and the public with the Academy's stance on factors determined to influence healthy pregnancy, as well as an overview of best practices in nutrition and healthy lifestyles during pregnancy.

The incidence of pregnancy outcomes for women with the purely obstetric form of antiphospholipid syndrome (APS) treated with prophylactic low-molecular-weight heparin (LMWH) plus low-dose aspirin (LDA) has not been documented. We observed women without a history of thrombosis who had experienced 3 consecutive spontaneous abortions before the 10th week of gestation or 1 fetal loss at or beyond the 10th week. We compared the frequencies of complications during new pregnancies between treated women with APS (n = 513; LMWH + LDA) and women negative for antiphospholipid antibodies as controls (n = 791; no treatment). Among APS women, prior fetal loss was a risk factor for fetal loss, preeclampsia (PE), premature birth, and the occurrence of any placenta-mediated complication. Being positive for anticardiolipin immunoglobulin M antibodies was a risk factor for any placenta-mediated complication. Among women with a history of recurrent abortion, APS women were at a higher risk than other women of PE, placenta-mediated complications, and neonatal mortality. Among women with prior fetal loss, LMWH + LDA-treated APS women had lower pregnancy loss rates but higher PE rates than other women. Improved therapies, in particular better prophylaxis of late pregnancy complications, are urgently needed for obstetric APS and should be evaluated according to the type of pregnancy loss.

Rising rates of diabetes in pregnancy have led to an escalation in research in this area. As in any area of clinical research, definitions of outcomes vary from study to study, making it difficult to compare research findings and draw conclusions. Our aim was to compile and create a repository of definitions, which could then be used universally. A systematic review of the literature was performed on published and ongoing randomized controlled trials in the area of diabetes in pregnancy between 01 Jan 2000 and 01 Jun 2012. Other sources included the World Health Organization and Academic Society Statements. The advice of experts was sought when appropriate definitions were lacking. Among the published randomized controlled trials on diabetes and pregnancy, 171 abstracts were retrieved, 64 full texts were reviewed and 53 were included. Among the ongoing randomized controlled trials published in ClinicalTrials.gov, 90 protocols were retrieved and 25 were finally included. The definitions from these were assembled and the final maternal definitions and foetal definitions were agreed upon by consensus. It is our hope that the definitions we have provided (i) will be widely used in the reporting of future studies in the area of diabetes in pregnancy, that they will (ii) facilitate future systematic reviews and formal meta analyses and (iii) ultimately improve outcomes for mothers and babies.

Context: Diabetes in pregnancy (DIP) is either pregestational or gestational. Aims: To determine the relationship between glycemic control and pregnancy outcomes in a cohort of DIP patients. Settings and Design: In this 12-month retrospective study, a total of 325 Saudi women with DIP who attended the outpatient clinics at a tertiary center Riyadh, Saudi Arabia, were included. Subjects and Methods: The patients were divided into two groups, those with glycated hemoglobin (HbA1c) ≤6.5% (48 mmol/mol) and those with glycated hemoglobin (HbA1c) above 6.5%. The two groups were compared for differences in maternal and fetal outcomes. Statistical Analysis Used: Independent Student's t-test and analysis of variance were performed for comparison of continuous variables and Chi-square test for frequencies. Odds ratio and 95% confidence intervals were calculated using logistic regression. Results: Patients with higher HbA1c were older (P = 0.0077), had significantly higher blood pressure, proteinuria (P < 0.0001), and were multiparous (P = 0.0269). They had significantly shorter gestational periods (P = 0.0002), more preterm labor (P < 0.0001), more perineal tears (P = 0.0406), more miscarriages (P < 0.0001), and more operative deliveries (P < 0.0001). Their babies were significantly of greater weight, had more Neonatal Intensive Care Unit (NICU) admissions, hypoglycemia, and macrosomia. Conclusions: Poor glycemic control during pregnancy is associated with adverse maternal and fetal outcomes (shortened gestational period, greater risk of miscarriage, increased likelihood of operative delivery, hypoglycemia, macrosomia, and increased NICU admission). Especially at risk are those with preexisting diabetes, who would benefit from earlier diabetes consultation and tighter glycemic control before conception. PMID:27366714

Background Twin pregnancies in low- and middle-income countries (LMICs) pose a high risk to mothers and newborns due to inherent biological risks and scarcity of health resources. We conducted a secondary analysis of the WHO Global Survey dataset to analyze maternal and perinatal outcomes in twin pregnancies and factors associated with perinatal morbidity and mortality in twins. Methods We examined maternal and neonatal characteristics in twin deliveries in 23 LMICs and conducted multi-level logistic regression to determine the association between twins and adverse maternal and perinatal outcomes. Results 279,425 mothers gave birth to 276,187 (98.8%) singletons and 6,476 (1.2%) twins. Odds of severe adverse maternal outcomes (death, blood transfusion, ICU admission or hysterectomy) (AOR 1.85, 95% CI 1.60–2.14) and perinatal mortality (AOR 2.46, 95% CI 1.40–4.35) in twin pregnancies were higher, however early neonatal death (AOR 2.50, 95% CI 0.95–6.62) and stillbirth (AOR 1.22, 95% CI 0.58–2.57) did not reach significance. Amongst twins alone, maternal age <18, poor education and antenatal care, nulliparity, vaginal bleeding, non-cephalic presentations, birth weight discordance >15%, born second, preterm birth and low birthweight were associated with perinatal mortality. Marriage and caesarean section were protective. Conclusions Twin pregnancy is a significant risk factor for maternal and perinatal morbidity and mortality in low-resource settings; maternal risk and access to safe caesarean section may determine safest mode of delivery in LMICs. Improving obstetric care in twin pregnancies, particularly timely access to safe caesarean section, is required to reduce risk to mother and baby. PMID:23936446

Background What role should previous cesarean section play in affecting clinical pregnancy outcomes and avoiding the complications of in vitro fertilization? In this article, we focus on elective single-embryo transfer (eSET) versus double-embryo transfer (DET) and assess the clinical efficacy and safety of eSET in patients who have a previous cesarean scar. Material/Methods The pregnancy, delivery, and neonatal outcomes of 130 patients who had a previous cesarean scar and received in vitro fertilization-embryo transfer (IVF-ET) were retrospectively analyzed. The number of transferred embryos was chosen depending on patients’ desire after acknowledging all benefits and risks, including eSET (eSET group, n=56) and DET (DET group, n=74). A total of 101 patients with previous vaginal delivery receiving IVF-ET in the same period were included as a control group. Results The pregnancy rates, multiple birth rates, abortion rates, ectopic pregnancy rates, gestational age at delivery, preterm birth rates, neonatal birth weight, and take-home baby rates were similar between the previous cesarean section group and the previous vaginal delivery group. A previous cesarean section scar did not affect embryo implantation and pregnancy outcomes in IVF. In the eSET and DET groups of previous cesarean section patients, the embryo implantation rates, pregnancy rates, abortion rates, and take-home baby rates were similar. However, the rate of multiple pregnancies reached 50% in the DET group, which led to more preterm births and lower birth weight. Conclusions Elective single-embryo transfer is a well-accepted strategy to avoid multiple pregnancies and improve the obstetric and neonatal outcomes of singleton pregnancy in IVF patients with a previous cesarean section.

The relationship between time from planned to achieved pregnancy and pregnancy outcome has been studied in a group of 18,658 workers in the textile, clothing and footwear industries. Information on pregnancy outcome and delay in conception in the period 1979-84 was collected by self administered questionnaires in 1985. The response rate was 70.3%. During the study period there had been 5,171 live births and 708 spontaneous abortions. Information on delay in conception was collected in broad categories. The data were analysed by means of a newly developed statistical parametric model in order to collect all possible information from the highly grouped data. Median waiting time before a pregnancy which ended in spontaneous abortion was 1.68 times longer than median waiting time before a pregnancy leading to a live birth. There seems to be a correlation between the length of the waiting time and abortion.

Teen pregnancy is associated with a host of deleterious outcomes for girls such as drug use and poor parenting. Thus, reducing teen pregnancy rates could improve long-term developmental outcomes for girls, improving adjustment during young adulthood. Based on the positive effects of Multidimensional Treatment Foster Care (MTFC) relative to group care (GC) in a study of adolescent girls-significantly fewer pregnancies reported in the 2-year follow-up for MTFC girls-the present study followed this sample into young adulthood (approximately 7 years postbaseline) to examine the effects of adolescent pregnancy on young adult substance use and pregnancy-related outcomes. All participants were randomly assigned to MTFC (n = 81) or GC (n = 85) as adolescents as part of two RCTs. Results from logistic regression analyses indicated that becoming pregnant during the 2-year follow-up was significantly related to illicit drug use, miscarriage from a new pregnancy, and child welfare involvement at 7 years postbaseline. In addition, baseline marijuana use predicted marijuana use at 7 years postbaseline.

Between July 1987 and January 1988, 44 patients with a tentative diagnosis of ectopic pregnancy underwent sonographic examination by means of vaginal probe at the Department of Gynecology and Obstetrics of the RWTH Aachen. The sonographic findings, all of which were confirmed by subsequent clinical and or surgical clarification, were as follows: an ectopic pregnancy was diganosed in 16 cases, an early intrauterine pregnancy in seven, an intrauterine abortion in seven, and in one case a uterine malformation-a dermoid cyst and a functional cyst. In 11 cases sonographic examination showed the interior genital region to be normal, with no sign of pregnancy. In the 16 ectopic pregnancies diagnosed, it was possible in 13 cases to visualize the pregnancy directly by sonography, including the amniotic sac, and to make measurements. In one case a normally developed ectopic pregnancy with living embryo was seen at the end of the seventh week of gestation post menstruationem. In the remaining three cases the diagnosis was established on the basis of an empty cavum uteri associated with a slightly enlarged uterus and demonstration of fluid in the pouch of Douglas. In two cases the ectopic pregnancy was correctly localized by "feeling" with the intravaginal probe to establish the cause of circumscribed pain. In three case the tentative diagnosis of an ectopic pregnancy made on the basis of sonographic findings was not confirmed by subsequent clarification procedures. The results described show that in most cases ectopic pregnancies can be demonstrated directly by sonography using an intravaginal probe.(ABSTRACT TRUNCATED AT 250 WORDS)

For heifers, beef and moderate-yielding dairy cows, it appears that the fertilisation rate generally lies between 90% and 100%. For high-producing dairy cows, there is a less substantive body of literature, but it would appear that the fertilisation rate is somewhat lower and possibly more variable. In cattle, the major component of embryo loss occurs in the first 16 days following breeding (Day 0), with emerging evidence of greater losses before Day 8 in high-producing dairy cows. In cattle, late embryo mortality causes serious economic losses because it is often recognised too late to rebreed females. Systemic concentrations of progesterone during both the cycle preceding and following insemination affect embryo survival, with evidence of either excessive or insufficient concentrations being negatively associated with survival rate. The application of direct progesterone supplementation or treatments to increase endogenous output of progesterone to increase embryo survival cannot be recommended at this time. Energy balance and dry matter intake during the first 4 weeks after calving are critically important in determining pregnancies per AI when cows are inseminated at 70-100 days after calving. Level of concentrate supplementation of cows at pasture during the breeding period has minimal effects on conception rates, although sudden reductions in dietary intake should be avoided. For all systems of milk production, more balanced breeding strategies with greater emphasis on fertility and feed intake and/or energy must be developed. There is genetic variability within the Holstein breed for fertility traits, which can be exploited. Genomic technology will not only provide scientists with an improved understanding of the underlying biological processes involved in fertilisation and the establishment of pregnancy, but also, in the future, could identify genes responsible for improved embryo survival. Such information could be incorporated into breeding objectives in

A study of all the mothers in the Northern region in 1983 whose pregnancies ended at between 24 and 31 weeks' gestation was undertaken. These pregnancies accounted for 1.3% of all the births and 44% of all the fetal and neonatal deaths in pregnancies that lasted more than 23 weeks. Most of the 389 singleton deliveries without malformations between 24 and 31 weeks were caused by spontaneous premature labour (n = 119, 31%), placental abruption (n = 79, 20%), pre-eclampsia (n = 56, 14%), and premature rupture of membranes (n = 48, 12%). The percentages of babies alive at the onset of delivery who survived the neonatal period were 66, 84, 78, and 73, respectively and the percentages of neonatal survivors with severe disabilities were 19, 13, 3, and 6, respectively. A further 65 (17%) of these babies died before the onset of labour for no obvious reason. The mode of delivery did not correlate with the outcome once the period of gestation at delivery was taken into account. The results highlight the inadequacy of the perinatal mortality index currently used in the United Kingdom, which identified 10.7 deaths/1000 registered births in 1983; 20% of the babies delivered at 24-31 weeks were excluded by this index because the birth went unregistered, as were 21% of all the babies born alive who died before discharge. An index that accounted for all babies weighing 500 g or more at birth irrespective of the period of gestation, and all neonatal (0-27 days) deaths, would be more appropriate and would bring reporting more into line with recommended international practice.

There is increasing evidence of the adverse impact of prenatal exposure to air pollution. This is of particular interest, as exposure during pregnancy--a crucial time span of important biological development--may have long-term implications. The aims of this review are to show current epidemiological evidence of known effects of prenatal exposure to air pollution and present possible mechanisms behind this process. Harmful effects of exposure to air pollution during pregnancy have been shown for different birth outcomes: higher infant mortality, lower birth weight, impaired lung development, increased later respiratory morbidity, and early alterations in immune development. Although results on lower birth weight are somewhat controversial, evidence for higher infant mortality is consistent in studies published worldwide. Possible mechanisms include direct toxicity of particles due to particle translocation across tissue barriers or particle penetration across cellular membranes. The induction of specific processes or interaction with immune cells in either the pregnant mother or the fetus may be possible consequences. Indirect effects could be oxidative stress and inflammation with consequent hemodynamic alterations resulting in decreased placental blood flow and reduced transfer of nutrients to the fetus. The early developmental phase of pregnancy is thought to be very important in determining long-term growth and overall health. So-called "tracking" of somatic growth and lung function is believed to have a huge impact on long-term morbidity, especially from a public health perspective. This is particularly important in areas with high levels of outdoor pollution, where it is practically impossible for an individual to avoid exposure. Especially in these areas, good evidence for the association between prenatal exposure to air pollution and infant mortality exists, clearly indicating the need for more stringent measures to reduce exposure to air pollution.

A serological test for chlamydial infection was administered to 281 Jerusalem women in order to determine the rate and influence of Chlamydia on pregnancy outcome. Serological indication of active infection was present in 7.8% of the tested women, while 15.3% were shown to be positive for Chlamydia. Among the ultraorthodox subpopulation of Mea Shearim, serological indication of active infection was present among 5.9% of the women, and 12.3% of this population tested positive. In comparison, women from the secular subpopulation had 12.7% serological indication of active infection and 22.95% tested positive (P < 0.01). There were no statistically significant differences between pregnancy duration, birthweight, incidence of premature uterine contractions, premature rupture of membranes, and postpartum febrile morbidity in the infected and noninfected groups. Women with a previous history of induced abortions showed a significantly higher evidence of past Chlamydia infection (9.3%) when compared with the women who did not have an infection (1.4%) (P < 0.006). Among the ultraorthodox women with positive or active infection, 41% had suffered at least one spontaneous abortion, as compared with 25% of the religious women who had no serological evidence of infection.

Abstract The effects of intimate partner violence (IPV) on maternal and neonatal outcomes are multifaceted and largely preventable. During pregnancy, there are many opportunities within the current health care system for screening and early intervention during routine prenatal care or during episodic care in a hospital setting. This article describes the effects of IPV on maternal health (e.g., insufficient or inconsistent prenatal care, poor nutrition, inadequate weight gain, substance use, increased prevalence of depression), as well as adverse neonatal outcomes (e.g., low birth weight [LBW]), preterm birth [PTB], and small for gestational age [SGA]) and maternal and neonatal death. Discussion of the mechanisms of action are explored and include: maternal engagement in health behaviors that are considered “risky,” including smoking and alcohol and substance use, and new evidence regarding the alteration of the hypothalamic-pituitary-adrenal axis and resulting changes in hormones that may affect LBW and SGA infants and PTB. Clinical recommendations include a commitment for routine screening of IPV in all pregnant women who present for care using validated screening instruments. In addition, the provision of readily accessible prenatal care and the development of a trusting patient–provider relationship are first steps in addressing the problem of IPV in pregnancy. Early trials of targeted interventions such as a nurse-led home visitation program and the Domestic Violence Enhanced Home Visitation Program show promising results. Brief psychobehavioral interventions are also being explored. The approach of universal screening, patient engagement in prenatal care, and targeted individualized interventions has the ability to reduce the adverse effects of IPV and highlight the importance of this complex social disorder as a top priority in maternal and neonatal health.

The literature was searched for publications on minerals and vitamins during pregnancy and the possible influence of supplements on pregnancy outcome. Maternal iron (Fe) deficiency has a direct impact on neonatal Fe stores and birth weight, and may cause cognitive and behavioural problems in childhood. Fe supplementation is recommended to low-income pregnant women, to pregnant women in developing countries, and in documented deficiency, but overtreatment should be avoided. Calcium (Ca) deficiency is associated with pre-eclampsia and intra-uterine growth restriction. Supplementation may reduce both the risk of low birth weight and the severity of pre-eclampsia. Gestational magnesium (Mg) deficiency may cause hematological and teratogenic damage. A Cochrane review showed a significant low birth weight risk reduction in Mg supplemented individuals. Intake of cereal-based diets rich in phytate, high intakes of supplemental Fe, or any gastrointestinal disease, may interfere with zinc (Zn) absorption. Zn deficiency in pregnant animals may limit fetal growth. Supplemental Zn may be prudent for women with poor gastrointestinal function, and in Zn deficient women, increasing birth weight and head circumference, but no evidence was found for beneficial effects of general Zn supplementation during pregnancy. Selenium (Se) is an antioxidant supporting humoral and cell-mediated immunity. Low Se status is associated with recurrent abortion, pre-eclampsia and IUGR, and although beneficial effects are suggested there is no evidence-based recommendation for supplementation. An average of 20-30% of pregnant women suffer from any vitamin deficiency, and without prophylaxis, about 75% of these would show a deficit of at least one vitamin. Vitamin B6 deficiency is associated with pre-eclampsia, gestational carbohydrate intolerance, hyperemesis gravidarum, and neurologic disease of infants. About 25% of pregnant women in India are folate deficient. Folate deficiency may lead to

This study examines the prevalence, behaviors, and birth outcomes associated with marijuana use in pregnancy. This was a retrospective cohort from a university-based prenatal care clinic from July 1, 2009 to June 30, 2010. The primary exposure was marijuana use, defined by self-report or urine toxicology. Demographic and outcome data were determined by chart review and analyzed by chi-square test, Fisher's exact test, ANOVA, and logistic regression. Three hundred and ninety-six patients initiated prenatal care during this time frame; 116 (29.3 %) of whom screened positive for marijuana at initial visit. Patients who used marijuana were less likely to have graduated high school (p = 0.016) or be employed (p = 0.015); they were more likely to use tobacco (p < 0.001) or alcohol (p = 0.032) and report a history of abuse (p = 0.010) or depressed mood (p = 0.023). When analyzed via logistic regression, only tobacco use remained associated with marijuana use (adjusted odds ratio (OR) = 3.3; 95 % confidence interval (CI): 1.9-5.9). Birth outcomes were available for 170 (43.0 %) patients. Only 3 (1.9 %) tested positive for marijuana at the time of delivery. Marijuana use was not related to incidence of low birth weight (13.8 % vs 14.0 %, p = 1.00), preterm delivery (17.7 % vs 12.0 %, p = 0.325), or NICU admissions (25.5 % vs 15.8 %, p = 0.139). Prenatal care utilization was equal between marijuana users and non-users. Although marijuana is common among obstetric patients at prenatal care initiation, most cease use by delivery. Marijuana is strongly correlated with cigarette use. We found no differences in birth outcomes or utilization of prenatal care by marijuana exposure.

Emerging evidence suggests that assisted hatching (AH) techniques may improve clinical pregnancy rates, particularly in poor prognosis patients; however, there still remains considerable uncertainty. We conducted a meta-analysis to verify the effect of AH on pregnancy outcomes. We searched for related studies published in PubMed, Web of Science, and Cochrane library databases from start dates to October 10, 2015. Totally, 36 randomized controlled trials with 6459 participants were included. Summary odds ratios (ORs) with 95% confidence intervals (CIs) for whether by AH or not were estimated. We found a significant increase in clinical pregnancy (OR = 1.16, 95% CI = 1.00–1.36, I2 = 48.3%) and multiple pregnancy rates (OR = 1.50, 95% CI = 1.11–2.01, I2 = 44.0%) with AH when compared to the control. Numerous subgroup analyses stratified by hatching method, conception mode, extent of AH, embryos transfer status, and previous failure history were also carried out. Interestingly, significant results of clinical pregnancy as well as multiple pregnancy rates were observed among women who received intracytoplasmic sperm injection, and who received AH which the zona were completely removed. In summary, this meta-analysis supports that AH was associated with an increased chance of achieving clinical pregnancy and multiple pregnancy. Whether AH significantly changes live birth and miscarriage rates needs further investigations. PMID:27503701

To describe social and economic inequalities in non-fatal pregnancy outcomes (low birth weight, preterm birth and small for gestational age births) in the neighbourhoods of the city of Barcelona (Spain), according to maternal age and maternal country of origin, between 1991 and 2005. A cross-sectional ecological study was carried out using the 38 neighbourhoods of Barcelona as the unit of analysis. The study population comprises the 192,921 live births to resident women aged 12-49 residing from 1991 to 2005. Information was gathered from births registry. Prevalence of low birth-weight, preterm birth and small for gestational age, was calculated for each of the 38 neighbourhoods of mothers' residence, stratifying results by maternal age and country of origin. The indicator of neighbourhood socio-economic level was the unemployment rate. Quartile maps along with Spearman correlation coefficients and linear regression were performed between indicators. The present study reports socio-economic inequalities in pregnancy outcomes among neighbourhoods in Barcelona (Spain): the more disadvantaged neighbourhoods have worse pregnancy outcomes (low birth weight, preterm birth and small for gestational age births) in all women age groups. These inequalities do not exist among immigrant women, and some groups of foreign mothers even have lower rates of low birth weight, preterm birth, and small for gestational age births than autochthonous women. The existing inequalities suggest that policy efforts to reduce these inequalities are not entirely successful and should focus on improving pregnancy and delivery care in less privileged women in a country with universal access to health care.

The chorionicity–based evaluation of the perinatal risk in twin pregnancies after assisted reproductive technology (ART) is lacking. A retrospective review was performed of all twin pregnancies monitored prenatally and delivered at our hospital between 2010 and 2014. Chorionicity was diagnosed by ultrasound examination at first trimester and confirmed by postnatal pathology. Pregnancy and perinatal outcomes were prospectively recorded. Adjusted odds ratios (aOR) with 95% confidence intervals (CI) were calculated in a logistic regression model. A total of 1153 twin pregnancies were analyzed. The occurrence of preterm premature rupture of membranes (PPROM) was 3 times as frequent in monochorionic diamniotic (MCDA) twin pregnancies after ART as in those spontaneous counterparts (aOR 3.0; 95%CI 1.1–3.2). The prevalence of intrahepatic cholestasis of pregnancies (ICP) was significantly higher in dichorionic diamniotic (DCDA) twin pregnancies following ART compared to spontaneous DCDA pregnancies (aOR 3.3; 95%CI 1.3–5.6). Perinatal outcomes did not differ between two conception methods, either in MCDA or DCDA twin pregnancies. Based on differentiation of chorionicity, ART is associated with the increased risk of PPROM in MCDA twin pregnancies and with a higher rate of ICP in DCDA twin gestations. ART does not increase adversity of perinatal outcomes in twin pregnancies. PMID:27243373

This study was carried out to explore associations between assisted reproductive technology (ART) and maternal and neonatal outcomes compared with similar outcomes following spontaneously conceived births. We conducted a retrospective cohort study of pregnancies conceived by ART (N = 2641) during 2006–2014 compared to naturally conceived pregnancies (N = 5282) after matching for maternal age and birth year. Pregnancy complications, perinatal complications and neonatal outcomes of enrolled subjects were investigated and analysed by multivariate logistic regression. We found that pregnancies conceived by in vitro fertilization (IVF) were associated with a significantly increased incidence of gestational diabetes mellitus, gestational hypertension, preeclampsia, intrahepatic cholestasis of pregnancy, placenta previa, placental abruption, preterm premature rupture of membranes, placental adherence, postpartum haemorrhage, polyhydramnios, preterm labour, low birth weight, and small-for-date infant compared with spontaneously conceived births. Pregnancies conceived by intracytoplasmic sperm injection (ICSI) showed similar elevated complications, except some of the difference narrowed or disappeared. Singleton pregnancies or nulliparous pregnancies following ART still exhibited increased maternal and neonatal complications. Therefore, we conclude that pregnancies conceived following ART are at increased risks of antenatal complications, perinatal complications and poor neonatal outcomes, which may result from not only a higher incidence of multiple pregnancy, but also the manipulation involved in ART processes.

While cocaine abuse in pregnancy is associated with a number of negative outcomes for both mothers and infants, it is unclear to what extent cocaine is specifically responsible for these negative outcomes and how its effects are distinct from those associated with substance abuse in general. Use of other drugs commonly associated with cocaine abuse, such as alcohol, marijuana, and tobacco, has also been associated with adverse pregnancy outcomes. Untoward pregnancy effects often ascribed to cocaine abuse in pregnancy may be more appropriately attributed to these or other drugs or to the unhealthy life-style associated with the long-term abuser rather than to cocaine itself. Epidemiologic data concerning cocaine use in pregnancy describe only associations of drug use and do not prove causality. Future research and longitudinal studies are needed to examine the roles of maternal and environmental factors in predicting differences in cocaine-exposed and nonexposed pregnancies.

Background Intrahepatic cholestasis of pregnancy (ICP) has important fetal implications. There is increased risk for poor fetal outcomes, including preterm delivery, meconium staining of amniotic fluid, respiratory distress, fetal distress and demise. Methods One hundred and one women diagnosed with ICP between January 2005 and March 2009 at San Francisco General Hospital were included in this study. Single predictor logistic regression models were used to assess the associations of maternal clinical and biochemical predictors with fetal complications. Clinical predictors analyzed included age, race/ethnicity, gravidity, parity, history of liver or biliary disease, history of ICP in previous pregnancies, and induction. Biochemical predictors analyzed included serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin, albumin, total protein, and total bile acids (TBA). Results The prevalence of ICP was 1.9%. Most were Latina (90%). Labor was induced in the majority (87%) and most were delivered by normal spontaneous vaginal delivery (84%). Fetal complications occurred in 33% of the deliveries, with respiratory distress accounting for the majority of complications. There were no statistically significant clinical or biochemical predictors associated with an increased risk of fetal complications. Elevated TBA had little association with fetal complications until reaching greater than 100 µmoL/L, with 3 out of 5 having reported complications. ICP in previous pregnancies was associated with decreased risk of fetal complications (OR 0.21, p = 0.046). There were no cases of late term fetal demise. Conclusions Maternal clinical and laboratory features, including elevated TBA, did not appear to be substantial predictors of fetal complications in ICP. PMID:22403605

Objective The goal of this study was to evaluate the etiologies and clinical outcomes of Korean recurrent pregnancy loss (RPL) patients. And also, we investigated the differences between primary and secondary RPL patients, between two and three or more pregnancy losses. Methods One hundred seventy eight women diagnosed as RPL were enrolled. We performed chromosomal analysis, thyroid stimulating hormone, prolactin, blood glucose, plasminogen activator inhibitor-1, natural killer cell proportion, anticardiolipin antibodies, antiphospholipid antibodies, lupus anticoagulant, anti-β2glycoprotein-1 antibodies, antinuclear antibody, protein C, protein S, antithrombin III, homocysteine, MTFHR gene, factor V Leiden mutation, and hysterosalphingography/hysteroscopic evaluation. Results The mean age was 34.03±4.30 years, and mean number of miscarriages was 2.69±1.11 (range, 2 to 11). Anatomical cause (13.5%), chromosomal abnormalities (5.6%), and endocrine disorders (34.3%) were observed in RPL women. Elevated natural killer cell and antiphospholipid antibodies were observed in 43.3% and 7.3% each. Among of 178 women, 77 women were pregnant. After management of those women, live birth rate was 84.4% and mean gestational weeks was 37.63±5.12. Women with three or more RPL compared with women with two RPL had more common anatomical cause such as intrauterine adhesions and lower rates of spontaneous pregnancy. Compare with secondary RPL women, immunological abnormalities were more common in primary RPL. However, miscarriage rates were not different. Conclusion Immunological factor including autoimmune and alloimmune disorders was most common etiology of RPL. Inherited thrombophilia showed different patterns with other ethnic countries. Miscarriage rates were not different between primary and secondary RPL, or between two and three or more miscarriages group. PMID:27668201

Objective: To document the neonatal outcomes of preterm birth in twin pregnancies and to investigate whether perinatal and obstetric parameters are associated with clinical outcomes. Methods: This retrospective trial was conducted on data gathered from 176 preterm twins delivered in the obstetrics and gynecology department of our tertiary care center. Data extracted from medical files of 88 pregnant women who gave preterm birth (at 260/7 to 366/7 gestational weeks) to twins were analyzed. Maternal/fetal descriptive and obstetric parameters, sonographic data, route of delivery, indication for cesarean section, birth weight, Apgar scores, head circumference, umbilical cord length and placental weight were noted. Results: The average age of the pregnant women was 28.8±6.4 years and ultrasonographic gestational age was 31.9±2.6 weeks. Apgar scores at 1st minute were affected significantly by fetal body weight (p=0.001), gestational age (p=0.001), height (p=0.004) and head circumference (p=0.011). None of these variables exhibited a noteworthy effect on Apgar scores at 5th minute. Conclusion: Efforts must be made to achieve advancement of gestational age until delivery in the follow-up preterm of twins. A well-established algorithm with special emphasis to risk factors is necessary to standardize and popularize the appropriate management strategy. PMID:27648040

OBJECTIVES: The overwhelming numbers of twins following assisted reproductive technology (ART) are dichorionic twins, but monochorionic twins account for around 0.9% of post ART pregnancies. The data for post ART-monochorionic pregnancy outcomes are scarce due to the rarity of this condition. Hence, we evaluated the obstetric outcomes of monochorionic and dichorionic pregnancies conceived on ART. SETTINGS: University teaching hospital. STUDY DESIGN: A case–control study of monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) pregnancies conceived following ART treatment. Charts of all women who conceived following ART from 2008 to 2013 were screened. Among them, the monochorionic twins diagnosed in the first trimester were included and their obstetric outcome was followed-up. For comparison, an equal number of dichorionic twin pregnancies from age and body mass index matched mothers was selected. RESULTS: The baseline clinical characteristics were similar between the two groups. MCDA group had a higher miscarriage rate (50%) than the DCDA group (10%), with three seconds trimester miscarriages in the MCDA group. The live birth rates were lower in the MCDA versus DCDA group (40% vs. 90%). Among triplet pregnancies with a monochorionic component, the live birth rate was only 25%. CONCLUSIONS: Monochorionic pregnancies following ART have poorer obstetric outcomes when compared to dichorionic pregnancies. For monochorionic pregnancies following ART, intensive antenatal surveillance at a tertiary level obstetric and neonatal center may help optimize the outcome. PMID:25191025

Acute kidney injury (AKI) is a rare but life-threatening complication of pregnancy. The aim of this paper is to study the characteristics of acute AKI in pregnancy and to emphasize on its management modalities in Moroccan hospitals. This is a national prospective study performed over six months from July 1 to December 31 2010 on AKI developing in pregnant patients, both preand post-partum period. Patients with pre-existing kidney disease were excluded from the study. Outcome was considered unfavorable when complete recovery of renal function was not achieved and/or maternal death occurred. Forty-four patients were included in this study. They were 29.6 ± 6 years old and mostly illiterate (70.6%). Most AKI occurred in the post-partum period, with 66% of the cases occurring in those who did not receive antenatal care. The main etiologies were pre-eclampsia (28 cases), hemorrhagic shock (six cases) and septic events (five cases). We noted three cases of acute fatty liver, one case of obstructive kidney injury and one case of lupus nephritis. Hemodialysis was necessary in 17 (38.6%) cases. The outcome was favorable in 29 patients. The maternal mortality rate was 11.4%. Two poor prognostic factors were identified: Age over 38 years and sepsis. AKI is a severe complication of pregnancy in developing countries. Its prevention necessitates the improvement of the sanitary infrastructure and the establishment of the obligatory antenatal care.

Objectives To assess the role of the health consequences of maternal overweight and obesity at the start of pregnancy on gestational pathologies, delivery and newborn characteristics. Methods A cohort of pregnant women (n = 6.558) having delivered at the Maternal & Child University Hospital of Gran Canaria (HUMIGC) in 2008 has been studied. Outcomes were compared using multivariate analyses controlling for confounding variables. Results Compared to normoweight, overweight and obese women have greater risks of gestational diabetes mellitus (RR = 2.13 (95% CI: 1.52–2.98) and (RR = 2.85 (95% CI: 2.01–4.04), gestational hypertension (RR = 2.01 (95% CI: 1.27–3.19) and (RR = 4.79 (95% CI: 3.13–7.32) and preeclampsia (RR = 3.16 (95% CI: 1.12–8.91) and (RR = 8.80 (95% CI: 3.46–22.40). Obese women have also more frequently oligodramnios (RR = 2.02 (95% CI: 1.25–3.27), polyhydramnios. (RR = 1.76 (95% CI: 1.03–2.99), tearing (RR = 1.24 (95% CI: 1.05–1.46) and a lower risk of induced deliveries (RR = 0.83 (95% CI: 0.72–0.95). Both groups have more frequently caesarean section (RR = 1.36 (95% CI: 1.14–1.63) and (RR = 1.84 (95% CI: 1.53–2.22) and manual placenta extraction (RR = 1.65 (95% CI: 1.28–2.11) and (RR = 1.77 (95% CI: 1.35–2.33). Newborns from overweight and obese women have higher weight (p<0.001) and a greater risk of being macrosomic (RR = 2.00 (95% CI: 1.56–2.56) and (RR = 2.74 (95% CI: 2.12–3.54). Finally, neonates from obese mother have a higher risk of being admitted to special care units (RR = 1.34 (95% CI: 1.01–1.77). Apgar 1 min was significantly higher in newborns from normoweight mothers: 8.65 (95% CI: 8.62–8.69) than from overweight: 8.56 (95% CI: 8.50–8.61) or obese mothers: 8.48 (95% CI: 8.41–8.54). Conclusion Obesity and overweight status at the beginning of pregnancy increase the adverse outcomes of the pregnancy. It is important to promote
Background The Global Network for Women's and Children's Health Research (Global Network) supports and conducts clinical trials in resource-limited countries by pairing foreign and U.S. investigators, with the goal of evaluating low-cost, sustainable interventions to improve the health of women and children. Accurate reporting of births, stillbirths, neonatal deaths, maternal mortality, and measures of obstetric and neonatal care is critical to efforts to discover strategies for improving pregnancy outcomes in resource-limited settings. Because most of the sites in the Global Network have weak registration within their health care systems, the Global Network developed the Maternal Newborn Health Registry (MNHR), a prospective, population-based registry of pregnancies at the Global Network sites to provide precise data on health outcomes and measures of care. Methods Pregnant women are enrolled in the MNHR if they reside in or receive healthcare in designated groups of communities within sites in the Global Network. For each woman, demographic, health characteristics and major outcomes of pregnancy are recorded. Data are recorded at enrollment, the time of delivery and at 42 days postpartum. Results From 2010 through 2013 Global Network sites were located in Argentina, Guatemala, Belgaum and Nagpur, India, Pakistan, Kenya, and Zambia. During this period, 283,496 pregnant women were enrolled in the MNHR; this number represented 98.8% of all eligible women. Delivery data were collected for 98.8% of women and 42-day follow-up data for 98.4% of those enrolled. In this supplement, there are a series of manuscripts that use data gathered through the MNHR to report outcomes of these pregnancies. Conclusions Developing public policy and improving public health in countries with poor perinatal outcomes is, in part, dependent upon understanding the outcome of every pregnancy. Because the worst pregnancy outcomes typically occur in countries with limited health registration
Plessinger, M A
Based on findings in humans and the confirmation of prenatal exposures in animals, amphetamines and methamphetamines increase the risk of an adverse outcome when abused during pregnancy. Clefting, cardiac anomalies, and fetal growth reduction deficits that have been seen in infants exposed to amphetamines during pregnancy have all been reproduced in animal studies involving prenatal exposures to amphetamines. The differential effects of amphetamines between genetic strains of mice and between species demonstrate that pharmacokinetics and the genetic disposition of the mother and developing embryo can have an enormous influence on enhancing or reducing these potential risks. The effects of prenatal exposure to amphetamines in producing altered behavior in humans appear less compelling when one considers other confounding variables of human environment, genetics, and polydrug abuse. In view of the animal data concerning altered behavior and learning tasks in comparison with learning deficits observed in humans, the influence of the confounding variables in humans may serve to increase the sensitivity of the developing embryo/fetus to prenatal exposure to amphetamines. These factors and others may predispose the developing conceptus to the damaging effects of amphetamines by actually lowering the threshold of susceptibility at the sites where damage occurs. Knowledge of the effects of prenatal exposure of the fetus and the mother to designer amphetamines is lacking. Based on the few studies in which designer drugs have been examined in animal models, more questions are raised than answered. Possible reasons why no malformations or significant fetal effects were found in the study by St. Omer include the genetic strain of rat used, the conservative exposure profile, or the fact that the placenta metabolized MDMA before reaching the embryo. These questions underscore the need for further investigations concerning the prenatal exposure effects of designer compounds and

We propose a semiparametric nonlinear mixed-effects model (SNMM) using penalized splines to classify longitudinal data and improve the prediction of a binary outcome. The work is motivated by a study in which different hormone levels were measured during the early stages of pregnancy, and the challenge is using this information to predict normal versus abnormal pregnancy outcomes. The aim of this paper is to compare models and estimation strategies on the basis of alternative formulations of SNMMs depending on the characteristics of the data set under consideration. For our motivating example, we address the classification problem using a particular case of the SNMM in which the parameter space has a finite dimensional component (fixed effects and variance components) and an infinite dimensional component (unknown function) that need to be estimated. The nonparametric component of the model is estimated using penalized splines. For the parametric component, we compare the advantages of using random effects versus direct modeling of the correlation structure of the errors. Numerical studies show that our approach improves over other existing methods for the analysis of this type of data. Furthermore, the results obtained using our method support the idea that explicit modeling of the serial correlation of the error term improves the prediction accuracy with respect to a model with random effects, but independent errors.

Adverse pregnancy outcomes entail a large health burden for the mother and offspring; a part of it might be avoided by better understanding the role of environmental factors in their etiology. Our aims were to review the assessment tools to characterize fecundity troubles and pregnancy-related outcomes in human populations and their sensitivity to environmental factors. For each outcome, we reviewed the possible study designs, main sources of bias, and their suggested cures. In terms of study design, for most pregnancy outcomes, cohorts with recruitment early during or even before pregnancy allow efficient characterization of pregnancy-related events, time-varying confounders, and in utero exposures that may impact birth outcomes and child health. Studies on congenital anomalies require specific designs, assessment of anomalies in medical pregnancy terminations, and, for congenital anomalies diagnosed postnatally, follow-up during several months after birth. Statistical analyses should take into account environmental exposures during the relevant time windows; survival models are an appropriate approach for fecundity, fetal loss, and gestational duration/preterm delivery. Analysis of gestational duration could distinguish pregnancies according to delivery induction (and possibly pregnancy-related conditions). In conclusion, careful design and analysis are required to better characterize environmental effects on human reproduction.

The highest relative risks of low birth weight are found among births to teenage mothers. An analysis of anthropometrics (weight, mid-arm circumference, and triceps skinfold) among black teenagers attending an adolescent prenatal program was studied. The sample consisted of 100 girls under 17 years. Data were collected from 19 to 35 weeks gestation. Adolescent mothers who delivered low birth weight (LBW) infants demonstrated different patterns of anthropometric changes than teen mothers who delivered normal birth weight (NBW) infants. Mean mid-arm circumference increases in the LBW group (0.05 mm/wk) were significantly less than mean increases in the NBW group (0.80 mm/wk) (p less than 0.05). Arm fat area estimates of the LBW mothers demonstrated weekly depletion (-24.9 mm2/wk), which was significantly less than those of the NBW group, who accumulated fat (+15.3 mm2/wk) (p less than .05). Changes in maternal nutritional status may in part mediate the birthweight outcome in adolescent pregnancy. Anthropometrics may be useful in predicting those teens at highest risk of bearing LBW infants.

We carried out a descriptive analysis on the pregnancy outcome in 313 pregnant women abused, 160 non-abused). Abuse was statistically significantly correlated with mean weight gain during pregnancy, mean frequency of the prenatal care, prolonged labour (dystocia), premature rupture of membrane, low mean birth weight and mean gestational age at birth. Given the high likelihood that a woman will access health care services during her pregnancy, physicians providing prenatal care are in a strategic position to screen for partner abuse.

Today, direct oral anticoagulants (DOAC) are widely used alternatives to Vitamin-K antagonists (VKA). Women of reproductive age may become pregnant during anticoagulation and, while VKA carry an embryotoxic potential, the risk of DOAC embryopathy is unknown. As a result, some patients elect to terminate pregnancy for fear of DOAC embryotoxicity. To assess the risk of DOAC embryopathy, we reviewed cases of DOAC exposure in pregnancy collected from physicians, literature and pharmacovigilance systems of drug authorities and manufacturers. A total of 357 reports including duplicates were available from which 233 unique cases could be identified. Information on pregnancy outcome was available in only 137/233 cases (58.8 %): 67 live births (48.9 %); 31 miscarriages (22.6 %); 39 elective pregnancy terminations (28.5 %). In 93 cases (39.9 %) no outcome data were available (including 3 cases of ongoing pregnancy). Of the 137 pregnancies with reported outcomes, seven showed abnormalities (5.1 %) of which three (2.2 %) could potentially be interpreted as embryopathy: live birth with facial dysmorphism; miscarriage in week 10 with limb abnormality; elective pregnancy termination due to a foetal cardiac defect in a woman who had to terminate a previous pregnancy due to Fallot tetralogy. Within its limitations (small numbers, incomplete outcome data) our results do not indicate that DOAC exposure in pregnancy carries a high risk of embryopathy or that DOAC exposure per se should be used to direct patient counselling towards pregnancy termination. Pregnancy outcome data are inconsistently captured in pharmacovigilance databases indicating the strong need for a more robust system of reporting.

Objective The contraceptive needs of illicit opioid users differ from non-drug users but are poorly understood. The aim of this study was to describe contraceptive use and pregnancy outcomes in opioid-using women, and to examine their association with a range of risk factors. Method This retrospective cohort study used UK general practice records, Treatment Outcomes Profile and National Drug Treatment Monitoring System data, and a nested data validation exercise. A cohort of 376 women aged 20–61 years were in active treatment for opioid addiction in October 2010 at two specialised primary care practices in North-East England. Outcomes were age-adjusted prevalence estimates for contraceptive use and pregnancy outcomes in users of illicit opioids. The association between lifestyle-related risk factors and contraception was explored. Results Drug-using women made lower use of planned (non-condom) contraception (24% vs 50%, p<0.001), had more frequent pregnancy terminations (0.46 vs. 0.025, p = 0.004) and higher annual incidence of chlamydia (1.1% vs. 0.33%, p<0.001), when compared with age-matched population data. Specifically, there was low use of oral contraceptives (4% vs. 25%, p<0.001), IUCD (1% vs. 6%, p<0.001), and sterilisation (7% vs. 6%, p = 0.053), but higher rates of injectable contraceptives (6% vs. 3%, p = 0.003). A total of 64% of children aged <16 years born to this group did not live with their mother. No individual risk factor (such as sex-working) significantly explained the lower use or type of non-condom contraception. Conclusions This is the first study to describe planned contraceptive use among drug-users, as well as the association with a range of risk factors and pregnancy outcomes. The low uptake of planned contraception, set against high rates of terminations and sexually transmitted disease demonstrates the urgent clinical need to improve contraceptive services, informed by qualitative work to explore the values and beliefs influencing

Background This study compared neonatal outcome and maternal complications in multiple pregnancies after assisted reproductive technologies (ART) to spontaneous pregnancies. Materials and Methods In this cross-sectional study, we reviewed medical records of 190 multiple pregnancies and births conceived by ART or spontaneous conceptions between 2004 and 2009 in Women Hospital. Obstetric history and outcomes were recorded and compared between these two groups. SPSS version 13 was used for data analysis. The results were analyzed using student’s t test, chi square and logistic regression (p<0.05). Results There were 106 deliveries from spontaneous conceptions and 84 that resulted from ART. Parity history and mode of delivery significantly differed between the two groups (p<0.001). The ART group had significantly higher preterm labor and premature rupture of membranes (PROM) whereas pregnanc-induced hypertension (PIH) was higher in the spontaneous group (p=0.01). Newborn intensive care unit (NICU) admission, duration of hospitalization, still birth and low gestational age were significantly higher in the ART group while neonatal jaundice was higher in the spontaneous group. Logistic regression analysis by considering neonatal complications as the dependent variable showed that respiratory distress syndrome (RDS), NICU admission and Apgar score were independent predictors for neonatal complications. Conclusion Obstetric and neonatal outcomes must be considered in multiple pregnancies conceived by ART. PMID:25780517

Background: Green spaces have been associated with improved physical and mental health; however, the available evidence on the impact of green spaces on pregnancy is scarce. Objectives: We investigated the association between surrounding greenness and birth weight, head circumference, and gestational age at delivery. Methods: This study was based on 2,393 singleton live births from four Spanish birth cohorts (Asturias, Gipuzkoa, Sabadell, and Valencia) located in two regions of the Iberian Peninsula with distinct climates and vegetation patterns (2003–2008). We defined surrounding greenness as average of satellite-based Normalized Difference Vegetation Index (NDVI) (Landsat 4–5 TM data at 30 m × 30 m resolution) during 2007 in buffers of 100 m, 250 m, and 500 m around each maternal place of residence. Separate linear mixed models with adjustment for potential confounders and a random cohort effect were used to estimate the change in birth weight, head circumference, and gestational age for 1-interquartile range increase in surrounding greenness. Results: Higher surrounding greenness was associated with increases in birth weight and head circumference [adjusted regression coefficients (95% confidence interval) of 44.2 g (20.2 g, 68.2 g) and 1.7 mm (0.5 mm, 2.9 mm) for an interquartile range increase in average NDVI within a 500-m buffer] but not gestational age. These findings were robust against the choice of the buffer size and the season of data acquisition for surrounding greenness, and when the analysis was limited to term births. Stratified analyses indicated stronger associations among children of mothers with lower education, suggesting greater benefits from surrounding greenness. Conclusions: Our findings suggest a beneficial impact of surrounding greenness on measures of fetal growth but not pregnancy length. PMID:22899599

Recently, large-scale trials of behavioural interventions have failed to show improvements in pregnancy outcomes. They have, however, shown that lifestyle support improves maternal diet and physical activity during pregnancy, and can reduce weight gain. This suggests that pregnancy, and possibly the whole periconceptional period, represents a 'teachable moment' for changes in diet and lifestyle, an idea that was made much of in the recent report of the Chief Medical Officer for England. The greatest challenge with all trials of diet and lifestyle interventions is to engage people and to sustain this engagement. With this in mind, we propose a design of intervention that aims simultaneously to engage women through motivational conversations and to offer access to a digital platform that provides structured support for diet and lifestyle change. This intervention design therefore makes best use of learning from the trials described above and from recent advances in digital intervention design.

Objective To examine the prevalence of snoring during pregnancy and its effects on key pregnancy outcomes. Methods Pregnant women were consecutively recruited in their first trimester. Habitual snoring was screened by using a questionnaire in the 1st and 3rd trimester, respectively. According to the time of snoring, participants were divided into pregnancy onset snorers, chronic snorers and non-snorers. Logistic regressions were performed to examine the associations between snoring and pregnancy outcomes. Results Of 3 079 pregnant women, 16.6% were habitual snorers, with 11.7% were pregnancy onset snorers and 4.9% were chronic snorers. After adjusting for potential confounders, chronic snorers were independently associated with gestational diabetes mellitus (GDM) (RR 1.66, 95%CI 1.09–2.53). Both pregnancy onset and chronic snorers were independently associated with placental adhesion (RR 1.96, 95%CI 1.17–3.27, and RR 2.33, 95%CI 1.22–4.46, respectively). Pregnancy onset snorers were at higher risk of caesarean delivery (RR 1.37, 95%CI 1.09–1.73) and having macrosomia (RR 1.54, 95%CI 1.05–2.27) and large for gestational age (LGA) (RR 1.71, 95%CI 1.31–2.24) infants. In addition, being overweight or obese before pregnancy plays an important role in mediating snoring and adverse pregnancy outcomes. Conclusions Maternal snoring may increase the risk of adverse pregnancy outcomes, and being overweight or obese before pregnancy with snoring is remarkable for researchers. Further studies are still needed to confirm our results. PMID:26871434

There are only few case reports in the literature documenting outcome of pregnancy in patients with DM in contrast with those of other connective tissue diseases especially when dermatomyositis is revealed during pregnancy, most of the publications reported a poor prognosis for both the mother and the fetus, yet, in our case we confirmed the results of the rare recent cases that have tended to show a good outcome, after the treatment with glucocorticoid and immunosuppressant therapy.

Pregnancy is rare in women with end-stage renal disease, and perinatal outcome remains suboptimal because of prematurity and foetal growth restriction. Successful obstetrical outcome in two women presented with chronic renal failure requiring serial haemodialysis and multiple blood transfusions during pregnancy is reported. Both women had vaginal delivery of low birth weight neonates--2100 g and 1540 g at 33 and 37 weeks' gestations respectively. With specialised neonatal care, both neonates survived, and the mothers were counselled for renal replacement therapy.

Familial Mediterranean fever (FMF) is an autosomal recessive disease affecting mainly patients of the Mediterranean basin and its major complication is the development of renal AA amyloidosis. On the other hand pregnancy with amyloidosis is not common; nevertheless, amyloidosis will complicate pregnancies also with the underlying disease and may cause terrible perinatal morbidities and mortalities. We report here the cases of five pregnant women and their pregnancy outcomes, who have been diagnosed with FMF complicated by renal amyloidosis. In the five cases, we observed that increased pregnancy complication such as small for gestational age, intrauterine growth restriction, preeclampsia and preterm birth.

OBJECTIVE--To evaluate the outcome of pregnancy in Finnish women after the accident at the Chernobyl nuclear power plant on 26 April 1986. DESIGN--Geographic and temporal cohort study. SETTING--Finland divided into three zones according to amount of radioactive fallout. SUBJECTS--All children who were exposed to radiation during their fetal development. Children born before any effects of the accident could be postulated--that is, between 1 January 1984 and 30 June 1986--served as controls. INTERVENTIONS--Children were divided into three temporal groups: controls, children who were expected to be born in August to December 1986, and children who were expected to be born in February to December 1987. They were also divided, separately, into three groups according to the three geographic zones. END POINT--Incidence of congenital malformations, preterm births, and perinatal deaths. MEASUREMENTS AND MAIN RESULTS--There were no significant differences in the incidence of malformations or perinatal deaths among the three temporal and three geographic groups. A significant increase in preterm births occurred among children who were exposed to radiation during the first trimester whose mothers lived in zones 2 and 3, where the external dose rate and estimated surface activity of caesium-137 were highest. CONCLUSIONS--The results suggest that the amount of radioactive fallout that Finnish people were exposed to after the accident at Chernobyl was not high enough to cause fetal damage in children born at term. The higher incidence of premature births among malformed children in the most heavily polluted areas, however, remains unexplained. PMID:2499391
The Eunice Kennedy Shriver National Institute of Child Health and Human Development’s Pregnancy and Perinatology Branch seeks partners interested in collaborative research to: (i) evaluate data and samples taken from women for potential biomarkers indicative for adverse pregnancy outcomes and (ii) co-develop diagnostic kits useful as predictors of adverse pregnancy outcomes.

Abstract Objectives: To assess the effects of tocilizumab on pregnancy outcomes in Japanese patients with rheumatic disease. Methods: Data from Chugai’s tocilizumab safety database (April 2005 to October 2014) were retrospectively analyzed to identify pregnancy outcomes in patients exposed to tocilizumab. Results: Data were available for 61 pregnancies exposed to tocilizumab, and outcomes were reported for 50 of those pregnancies. In 36 births, no congenital anomalies were identified; however, six neonatal abnormalities were reported: five cases of low birth weight (<2500 g) and one case of neonatal asphyxia. Of 36 births, tocilizumab was resumed during lactation in two patients, with no subsequent adverse events reported in newborns. The spontaneous abortion rate was 18.0% (9 of 50 pregnancies), which is comparable to the rate in the general population. The five terminated pregnancies included one case of caudal regression syndrome. Conclusions: The present retrospective study of 61 pregnancies exposed to tocilizumab at conception indicated no increased rates of spontaneous abortion or congenital abnormalities in patients with rheumatic disease. However, further study is necessary to confirm the benefit-risk profile of tocilizumab treatment during pregnancy. PMID:26873562

Our aim was to assess the long-term outcomes of infants born out of a pregnancy complicated by unexplained polyhydramnios. We retrospectively analysed a cohort of 173 singleton pregnancies with polyhydramnios. There were 24 singletons with unexplained polyhydramnios, defined as polyhydramnios where prenatal testing was negative. Infants were examined by a paediatrician at a median age of 12 months (range 12-64 months). Of the 24 infants, 19 (79%) had a normal outcome. West syndrome, polyuria and pulmonary stenosis were diagnosed in three children during follow up, while there were two perinatal deaths. Paediatric follow up of children born out of pregnancies complicated by unexplained polyhydramnios should be carried out systematically.

The Patient-Centered Outcomes Research Institute is funding 8 comparative effectiveness research projects to improve patient-centered outcomes for African American and Hispanic/Latino patients with uncontrolled asthma. These projects aim to compare multilevel interventions with known efficacy at the community, home, and health system levels to enhance patient and clinician uptake of the National Heart, Lung, and Blood Institute's National Asthma Education Prevention Program guidelines and improve outcomes. The National Asthma Education Prevention Program guidelines provide clinicians with a range of acceptable approaches for the diagnosis and management of asthma and define general practices that meet the needs of most patients. Yet disparities in asthma care and outcomes remain pervasive for African Americans and Hispanics/Latinos. The National Heart, Lung, and Blood Institute AsthmaNet consortium has identified several top research priorities for pediatric and adult populations, including a recommendation to examine tailored approaches based on race/ethnicity. In addition, the guidelines emphasize the need for studies that focus on multicomponent interventions recognizing that single interventions are generally ineffective. This article will describe the Patient-Centered Outcomes Research Institute-funded asthma projects and how they are individually and collectively addressing evidence gaps in asthma care by focusing on multicomponent and tailored approaches for improving outcomes and reducing disparities for African American and Hispanic/Latino patients.

Previous reports suggest that renal involvement before pregnancy or active renal disease during pregnancy may be associated with poor fetal and maternal outcomes in systemic lupus erythematosus (SLE) women. We report our experience of fetal and maternal complications in pregnant lupus women with and without previous lupus nephritis. We analyzed the clinical records of pregnant SLE patients attended in a tertiary reference center during a 5-year period. Patients were allocated into two groups according to the presence or absence of previous lupus nephritis. Women were evaluated monthly during pregnancy and at least 1 month postpartum. Maternal and fetal outcomes of pregnancy were abstracted. We included 95 pregnancies in 92 patients. Compared with pregnant women without lupus nephritis (n = 60), pregnancies with previous lupus nephritis (n = 35) were associated with a higher risk of maternal complications (88.5% vs. 43.3%, p = 0.00001), higher rate of lupus flares (54.2% vs. 25%, p = 0.004), and renal flares (45.7% vs. 6.6%, p = 0.00001), but most of which in most instances were reversible. On the other hand, fetal outcome was similar in both groups. Multivariate analysis showed that previous lupus nephritis and active lupus at conception were predictors of adverse maternal outcome. Pregnancies in women with previous lupus nephritis had a higher rate of maternal complications in comparison with those without. However, fetal prognosis was similar in both groups.
Single umbilical artery is the most common congenital abnormality of the umbilical cord and is seen in 4-11% of twin pregnancies. It is usually associated with intrauterine growth retardation, preterm labour, small-for-dates and other structural anomalies. There is no significant difference in the incidence between monochorionic and dichorionic twins. The left artery is usually absent more commonly than the right. The female co-twin was predominantly more affected than their male counterparts. Single umbilical artery is found twice more common in white women than in Afro-Asians and Americans. The hemodynamic disturbances occur early in the embryonic development, influence greatly in the development of single umbilical artery. Genetic and environmental factors also play a major role in the development of this anomaly. The pregnancies with single umbilical artery were classified as high risk group, because the overall perinatal mortality rate was estimated to be as high as 20%. There is a significant increase in the occurrence of single umbilical artery in pregnancies due to artificial reproductive technologies, as well as in spontaneous miscarriages. Prenatal ultrasonography is the principal diagnostic technique employed to identify single umbilical artery during 3rd trimester of pregnancy. The present case, reports the presence of a single umbilical artery in a monozygotic, monochorionic twin pregnancy, which is acardiac-acephalic fetus, small for dates, female sex, associated with other major structural anomalies, and was still born. Authors analyse its incidence, clinical presentations and pregnancy outcome and also review the pertinent literature. PMID:25737967

In this paper, a generalized logistic regression model for correlated observations is used to analyze epidemiologic data on the frequency of spontaneous abortion among a group of women office workers. The results are compared to those obtained from the use of the standard logistic regression model that assumes statistical independence among all the pregnancies contributed by one woman. In this example, the correlation among pregnancies from the same woman is fairly small and did not have a substantial impact on the magnitude of estimates of parameters of the model. This is due at least partly to the small average number of pregnancies contributed by each woman.

Mounting evidence from clinic and convenience samples suggests that stress is an important predictor of adverse obstetric outcomes. Using a proposed theoretical framework, this review identified and synthesized the population-based literature on the measurement of stress prior to and during pregnancy in relation to obstetric outcomes. Population-based, peer-reviewed empirical articles that examined stress prior to or during pregnancy in relation to obstetric outcomes were identified in the PubMed and PsycInfo databases. Articles were evaluated to determine the domain(s) of stress (environmental, psychological, and/or biological), period(s) of stress (preconception and/or pregnancy), and strength of the association between stress and obstetric outcomes. Thirteen studies were evaluated. The identified studies were all conducted in developed countries. The majority of studies examined stress only during pregnancy (n = 10); three examined stress during both the preconception and pregnancy periods (n = 3). Most studies examined the environmental domain (e.g. life events) only (n = 9), two studies examined the psychological domain only, and two studies examined both. No study incorporated a biological measure of stress. Environmental stressors before and during pregnancy were associated with worse obstetric outcomes, although some conflicting findings exist. Few population-based studies have examined stress before or during pregnancy in relation to obstetric outcomes. Although considerable variation exists in the measurement of stress across studies, environmental stress increased the risk for poor obstetric outcomes. Additional work using a lifecourse approach is needed to fill the existing gaps in the literature and to develop a more comprehensive understanding of the mechanisms by which stress impacts obstetric outcomes.

Parents are usually told that many anencephalic offspring die in utero or soon after delivery, and many obstetricians offer elective termination of the pregnancy. Following the personal experience of the first author, a personal website was created with the intention of providing information and exchanging views with other parents confronted with a prenatal diagnosis of anencephaly. Data were collected from 211 pregnancies where the parents opted not to terminate pregnancy. These data revealed that polyhydramnios was a feature in 56 (26%) pregnancies, death in utero in 15 (7%) pregnancies, 72 (34%) babies were born prematurely (<37 weeks of gestation), 113 (53%) at term and 21 (10%) after 42 weeks. Stillbirth, presumably resulting from intrapartum death, occurred in 43 (20%) deliveries. One hundred and fifty-three (72%) of anencephalic offspring were liveborn, of those, 103 (67%) died within 24 hours but 6/211 survived 6 or more days (maximum 28 days). Continuation of pregnancy after a diagnosis of anencephaly is medically safe and should be considered as an option.

Hip fractures are a very serious socio-economic problem in western countries. Since the 1950s, orthogeriatric units have introduced improvements in the care of geriatric patients admitted to hospital because of hip fractures. During this period, these units have reduced mean hospital stays, number of complications, and both in-hospital mortality and mortality over the middle term after hospital discharge, along with improvements in the quality of care and a reduction in costs. Likewise, a recent clinical trial has reported greater functional gains among the affected patients. Studies in this field have identified the prognostic factors present upon admission or manifesting themselves during admission and that increase the risk of patient mortality or disability. In addition, improved care afforded by orthogeriatric units has proved to reduce costs. Nevertheless, a number of management issues remain to be clarified, such as the optimum anesthetic, analgesic, and thromboprophylactic protocols; the type of diagnostic and therapeutic approach best suited to patients with cognitive problems; or the efficiency of the programs used in convalescence units or in home rehabilitation care. Randomized clinical trials are needed to consolidate the evidence in this regard. PMID:27445466

The conflicting results from studies on the predictive capabilities of serum anti-Müllerian hormone (AMH) for IVF pregnancy outcomes may be attributed to small sample sizes and disparities in the age of the study populations. The relationship between AMH and IVF pregnancy outcomes was clarified with retrospective cross-tabulation analyses (n=1558) stratified by age to control for its confounding effects. Serum AMH concentrations were divided into tertiles (≤ 0.29, 0.30-1.20, ≥ 1.21 ng/ml) and ages into four groups (<34, 34-37, 38-41, ≥ 42 years). For women <34, having serum AMH in the lowest tertile did not reduce the chance of IVF pregnancy/live birth compared with those with higher AMH concentrations. For women 34-41, a significant positive relationship existed between serum AMH and pregnancy rates. For women ≥ 42, serum AMH concentrations ≤ 0.29 ng/ml were associated with a 3% chance of pregnancy, and women with AMH ≥ 1.21 ng/ml had the same pregnancy rate as women with concentrations 0.30-1.20 ng/ml. In conclusion, AMH has limited predictive value for IVF outcomes in the two extremes of female reproductive age; however, for women between 34 and 41, higher serum AMH concentrations are associated with significantly greater chances of pregnancy (P<0.01).

In an era of Sustainable Development Goals, maternal, newborn, and child health still require improvement. Continuum of care is considered key to improving the health status of these populations. The continuum of care is a series of care strategies starting from pre-pregnancy to motherhood-childhood. The effectiveness of such linkage between the pregnancy, birth, and postnatal periods has been demonstrated. However, almost no study has assessed the impact of linkage that starts from pre-pregnancy to pregnancy care on maternal and child health. The present study attempts to fill this gap by assessing the effectiveness of the care linkage between pre-pregnancy and pregnancy care for reducing neonatal, perinatal, and maternal mortality in low- and middle-income countries. We performed a systematic review and meta-analysis of randomized and quasi-randomized controlled trials in low- and middle-income countries. The outcome variables were neonatal, perinatal, and maternal mortality. We searched databases such as PubMed/Medline, POPLINE, EBSCO/CINAHL, and ISI Web of Science for the period 2000–2014, using broad search terms (e.g., pre-pregnancy OR adolescent OR mother), combined with search terms specific for interventions, (e.g., family planning OR contraception OR spacing). From the 1,325 retrieved articles, five studies were finally analyzed. The meta-analysis showed that interventions linking pre-pregnancy and pregnancy care effectively reduced neonatal mortality (risk ratio [RR]: 0.79; 95% confidence interval [CI]: 0.71–0.89, I2 = 62%) and perinatal mortality (RR: 0.84; 95% CI: 0.75–0.94, I2 = 73%), but did not show an effect on maternal mortality. Neonatal and perinatal mortality could be reduced by linking pre-pregnancy and pregnancy care. This linkage of pre-pregnancy and pregnancy cares is an essential component of continuum of care to improve newborn health.

The purpose of this study is to evaluate whether follicle-stimulating hormone treatment improves sperm DNA parameters and pregnancy outcome in infertile male candidates to in-vitro fertilization.Observational study in 166 infertile male partners of couples undergoing in-vitro fertilization. Eighty-four patients were receiving follicle-stimulating hormone treatment (cases) and 82 refused treatment (controls). Semen parameters, sexual hormones, and sperm nucleus (fluorescence in-situ hybridization, acridine orange, TUNEL, and γH2AX) were evaluated at baseline (T0) and after 3 months (T1), when all subjects underwent assisted reproduction techniques. Statistical analysis was performed by analysis of variance.Compared to baseline, cases showed significant improvements in seminal parameters and DNA fragmentation indexes after follicle-stimulating hormone therapy (all P < 0.05), whereas no changes were observed in controls. Within cases, follicle-stimulating hormone treatment allowed to perform intrauterine insemination in 35 patients with a pregnancy rate of 23.2 %. Intracytoplasmic sperm injection was performed in all controls and in 49 patients from cases, with pregnancy rates of 23.2 and 40.8 %, respectively (P < 0.05). After 3 months (T0 vs. T1) of follicle-stimulating hormone therapy, cases with positive outcome had reduced DNA fragmentation index and lower double strand breaks (P < 0.05 and P < 0.001 vs. negative outcome, respectively).In this observational study, we showed that follicle-stimulating hormone treatment improves sperm DNA fragmentation, which in turn leads to increased pregnancy rates in infertile males undergoing in-vitro fertilization. In particular, double strand breaks (measured with γH2AX test) emerged as the most sensible parameter to follicle-stimulating hormone treatment in predicting reproductive outcome.

The healthcare environment has been impacted tremendously by higher patient acuity, cost-cutting measures, an increase in litigation, and increased expectations by an educated generation of healthcare consumers. This has led to the need to continually measure, assess, and improve quality. These activities must consider not only patient clinical outcomes, but also customer service ratings and financial outcomes. Quality improvement requires a collaborative approach to succeed, and the need to build a cohesive and effective multidisciplinary team is critical for positive outcomes. Strategies to build a culture of teamwork include incorporating total quality management principles into every level of the organization, seeking participation from every discipline and level of the organization, and recognizing employees for their efforts. Infusion nurses have an excellent opportunity to contribute their expertise to any multidisciplinary team that impacts the outcomes of infusion patients. In addition, team-building and quality improvement may prove to be excellent career moves for infusion nurses looking to further specialize their practice.

Low back pain in pregnancy is a common occurrence and is mainly caused by hormonal and biomechanical changes. Patients with pregnancy-induced low back pain (PILBP) frequently complain of moderate to severe and disabling pain often restricting their daily activities. In these cases, a “watch and wait” approach cannot be the best solution. On the basis of anamnesis and examination PILBP can be divided into three subgroups: pregnancy-related low back pain (PLBP), pelvic girdle pain (PGP) and the combination of PLBP and PGP. The three entities ask for different diagnostic workups and therapeutic modalities. There are many possible treatments for PLBP, however, only a few are based on sound evidence. Information and advice, exercise and training programs, acupuncture, stabilizing belts and analgesic medication can have a positive impact on pain and disability. PGP und PLBP respond well to chiropractic interventions.

Antenatal care (ANC) has been shown to influence infant and maternal outcomes. WHO recommends 4 ANC visits for uncomplicated pregnancies. However, pregnant women in Ghana are required to attend 8-13 antenatal visits. We investigated the association of ANC attendance with adverse pregnancy outcomes (defined as low infant birth weight, stillbirth, preterm delivery or small for gestational age). A quantitative cross-sectional study was conducted on 629 women, age 19-48 years who presented for delivery at two selected public hospitals and 16 traditional birth attendants from July to November 2011. Socio-demographic and antenatal information were collected using a structured questionnaire. ANC attendance, medical and obstetric/gynecological history were abstracted from maternal antenatal records. Data were analyzed using Chi square and logistic regression. Twenty-two percent of the women experienced an adverse outcome. Eleven percent of the women attended <4 ANC visits. In an unadjusted model, these women had an increased likelihood of experiencing an adverse outcome (OR 2.27; 95% CI 1.30-3.94; p = 0.0038). High parity (>5 children) was also associated with adverse birth outcomes. Women screened for syphilis or use of insecticide-treated bed nets had a 40 and 36% (p = 0.0447 and p = 0.0293) reduced likelihood of experiencing an adverse pregnancy outcome respectively. After adjusting for confounders, attending <4 antenatal visits was associated with adverse pregnancy outcome compared with ≥4 ANC visits (Adjusted OR 2.55; 95% CI 1.16-5.63; p = 0.0202). Attending <4 antenatal visits and high parity were associated with adverse pregnancy outcomes for uncomplicated pregnancies.

Unintended pregnancy is a global sexual health problem. Outcomes of unintended pregnancy include unwanted childbirth and abortion, which may be associated with negative physical and psychosocial health implications for women. In Scotland, the Scottish Sexual Health Strategy has the stated goal of improving the sexual health of the people of Scotland. One aim of the Strategy is to reduce rates of unintended pregnancy and one policy designed to achieve this is 'widening access to emergency contraception'. This paper examines the success of this policy with reference to the implicit link it makes between expanding access to emergency contraception and increasing its effective use, aiming thereby to reduce rates of unintended pregnancy. Since there is evidence that previous policies and strategies expanding access to emergency contraception have failed to reduce such rates, alternative approaches to achieve a reduction in unintended pregnancies are discussed.

Reduced capability of the uterus to support pregnancy in the absence of its interaction with secretions from male accessory glands has been demonstrated in rodents and to some extent in pigs. However, in cattle, the role of postmating inflammatory response on pregnancy success has not been studied. The current study examined the influence of uterine presensitization with seminal antigens at breeding on pregnancy outcome in cows. Lactating beef (n=1090) and dairy (n=800) cows received 0.5 mL seminal plasma (SP), 40 ng recombinant human transforming growth factor-beta1 (rhTGF-beta1), or 0.5 mL bovine serum albumin (BSA), or were left untreated before or at insemination. Semen was deposited into the anterior cervix using a second insemination gun. Pregnancy was diagnosed at 35 to 40 d postinsemination by transrectal ultrasonography or from records of calves born the subsequent calving season. Pregnancy rates in beef cows did not differ among treatments but differed among trials (69.8%, 52.5% vs. 40.3%; P<0.05). In trials where average pregnancy rates were below 50%, treatments with TGF-beta1 but not SP tended (P<0.07) to increase pregnancy rates in beef cows. In dairy cows, SP and TGF-beta1 improved pregnancy outcome by 10 percentage points, but these increments did not achieve statistical significance. In conclusion, this study did not find any conclusive evidence for the effect of TGF-beta1 or seminal plasma on pregnancy outcome in lactating dairy or beef cows but realized marginal improvements when pregnancy rates were below 50% (compromised fertility).
Background. This case report discusses the pregnancy outcome of a patient with cartilage-hair hypoplasia, a rare form of dwarfism, and multiple previous orthopedic surgeries. Literature on pregnancy outcomes in patients with cartilage-hair hypoplasia is limited. Case. A 32-year-old patient with cartilage-hair hypoplasia presented at 12 weeks' gestation to the high-risk obstetrics clinic for care. Preterm labor resulted in cesarean delivery at 34 weeks' gestation with general anesthetic. Breastfeeding was stopped at 6 weeks due to neonatal complications. Conclusion. Pregnancy and delivery were uncomplicated. A multidisciplinary approach allowed for effective management during pregnancy and postnatal care. This is the first known documented case of prenatal care, delivery, and breastfeeding in a woman with this rare disorder. PMID:28251002

We evaluated pregnancy outcomes among women with hyperemesis gravidarum (HG) in a North London multi-ethnic population. A retrospective case-control study was performed on records of obstetric admissions during a 4-year period, at North Middlesex University Hospital in North London. A total of 208 women with HG were identified according to Fairweather's criteria occurring in the first 20 weeks of pregnancy, which is severe enough to require admission to hospital. The control study group consisted of 208 women without HG, matched for age, ethnicity and parity. Maternal characteristics as well as pregnancy outcomes were compared in the two groups. The incidence of a delivery of a small-for-gestational-age (SGA) neonate below the 10th per centile was significantly higher in the HG group compared with unaffected pregnancies (8.7% vs 16.8%, p = 0.01). Hyperemesis gravidarum in a multi-ethnic population in North London is associated with SGA neonates.

During the last several decades, colorectal cancer surgery has experienced some major perioperative improvements. Preoperative risk-assessment of nutrition, frailty, and sarcopenia followed by interventions for patient optimization or an adapted surgical strategy, contributed to improved postoperative outcomes. Enhanced recovery programs or fast-track surgery also resulted in reduced length of hospital stay and overall complications without affecting patient safety. After an initially indecisive start due to uncertainty about oncological safety, the most significant improvement in intraoperative care was the introduction of laparoscopy. Laparoscopic surgery for colon and rectal cancer is associated with better short-term outcomes, whereas long-term outcomes regarding survival and recurrence rates are comparable. Nevertheless, long-term results in rectal surgery remain to be seen. Early recognition of anastomotic leakage remains a challenge, though multiple improvements have allowed better management of this complication. PMID:25253944

OBJECTIVE To evaluate associations between prepregnancy lifestyle factors, psychological distress and adverse pregnancy outcomes among female survivors of childhood cancer. STUDY DESIGN We examined pregnancies of 1,192 female participants from the Childhood Cancer Survivor Study. Generalized linear models, adjusted for age at diagnosis, age at pregnancy, parity, and education were used to calculate the odds ratio (OR) and confidence interval (CI) for associations between prepregnancy inactivity, overweight or obese status, smoking status, risky drinking, psychological distress and pregnancy outcomes. Interactions between lifestyle factors, psychological distress, type of cancer and cancer treatment were assessed in multivariable models. RESULTS The median age of study participants at the beginning of pregnancy was 28 years (range: 14–45). Among 1,858 reported pregnancies, there were 1,300 singleton live births (310 were preterm), 21 stillbirths, 397 miscarriages, and 140 medical abortions. Prepregnancy physical inactivity, risky drinking, distress and depression were not associated with any pregnancy outcomes. Compared to those who had never smoked, survivors with > 5 pack-years smoking history had a higher risk for miscarriage among those treated with > 2.5 Gy uterine radiation (OR: 53.9; 95% CI: 2.2, 1,326.1) than among those treated with ≤ 2.5 Gy uterine radiation (OR: 1.9; 95% CI: 1.2, 3.0). There was a significant interaction between smoking and uterine radiation (Pinteraction = 0.01). CONCLUSION While most lifestyle factors and psychological distress were not predictive of adverse pregnancy outcomes, the risk for miscarriage was significantly increased among survivors exposed to > 2.5 Gy uterine radiation who had a history of smoking.

Renal angiomyolipoma is a rare benign tumour and its occurrence during pregnancy is even rare. It is usually diagnosed incidentally. It can increase in size during pregnancy and can present acutely as rupture with retroperitoneal haemorrhage, mechanism of which is still unclear. We present a case of successful pregnancy outcome in a patient with congenital solitary kidney affected by angiomyolipoma, diagnosed incidentally at 19 years of age. The patient had conceived twice. Her antenatal and post partum period was uneventful both the times. PMID:27891407
Background Preterm birth is a global problem, with a prevalence of 8 to 12% depending on location. Several large trials and systematic reviews have shown progestogens to be effective in preventing or delaying preterm birth in selected high risk women with a singleton pregnancy (including those with a short cervix or previous preterm birth). Although an improvement in short term neonatal outcomes has been shown in some trials these have not consistently been confirmed in meta-analyses. Additionally data on longer term outcomes is limited to a single trial where no difference in outcomes was demonstrated at four years of age of the child, despite those in the “progesterone” group having a lower incidence of preterm birth. Methods/Design The OPPTIMUM study is a double blind randomized placebo controlled trial to determine whether progesterone prophylaxis to prevent preterm birth has long term neonatal or infant benefit. Specifically it will study whether, in women with singleton pregnancy and at high risk of preterm labour, prophylactic vaginal natural progesterone, 200 mg daily from 22 – 34 weeks gestation, compared to placebo, improves obstetric outcome by lengthening pregnancy thus reducing the incidence of preterm delivery (before 34 weeks), improves neonatal outcome by reducing a composite of death and major morbidity, and leads to improved childhood cognitive and neurosensory outcomes at two years of age. Recruitment began in 2009 and is scheduled to close in Spring 2013. As of May 2012, over 800 women had been randomized in 60 sites. Discussion OPPTIMUM will provide further evidence on the effectiveness of vaginal progesterone for prevention of preterm birth and improvement of neonatal outcomes in selected groups of women with singleton pregnancy at high risk of preterm birth. Additionally it will determine whether any reduction in the incidence of preterm birth is accompanied by improved childhood outcome. Trial registration ISRCTN14568373 PMID

Objective: To investigate the association between neuromyelitis optica spectrum disorder (NMOSD) and pregnancy outcome. Methods: An international cohort of women with aquaporin-4 antibody–positive NMOSD and ≥1 pregnancy was studied retrospectively. Multivariate logistic regression was used to investigate whether pregnancy after NMOSD onset was associated with an increased risk of miscarriage (cohort of 40 women) or preeclampsia (cohort of 57 women). Results: Miscarriage rate was higher in pregnancies after NMOSD onset (42.9% [95% confidence interval 17.7%–71.1%] vs 7.04% [2.33%–15.7%]). Pregnancies conceived after, or up to 3 years before, NMOSD onset had an increased odds ratio of miscarriage (7.28 [1.03–51.6] and 11.6 [1.05–128], respectively), independent of maternal age or history of miscarriage. Pregnancies after, or up to 1 year before, NMOSD onset ending in miscarriage were associated with increased disease activity from 9 months before conception to the end of pregnancy, compared to viable pregnancies (mean annualized relapse rate 0.707 vs 0.100). The preeclampsia rate (11.5% [6.27%–18.9%]) was significantly higher than reported in population studies. The odds of preeclampsia were greater in women with multiple other autoimmune disorders or miscarriage in the most recent previous pregnancy, but NMOSD onset was not a risk factor. Conclusions: Pregnancy after NMOSD onset is an independent risk factor for miscarriage, and pregnancies conceived at times of high disease activity may be at increased risk of miscarriage. Women who develop NMOSD and have multiple other autoimmune disorders have greater odds of preeclampsia, independent of NMOSD onset timing. PMID:26581304

The maternal microbiome is recognized as a key determinant of a range of important maternal and child health outcomes, and together with perinatal factors influences the infant microbiome. This manuscript provides a summary review of research investigating: (1) the role of the maternal microbiome in pregnancy outcomes known to adversely influence neonatal and infant health, including preterm birth, cardiometabolic complications of pregnancy such as preeclampsia and gestational diabetes, and excessive gestational weight gain; (2) factors with an established link to adverse pregnancy outcomes that are known to influence the composition of the maternal microbiome; and (3) strategies for promoting a healthy maternal microbiome, recognizing that much more research is needed in this area.

Background Women in Nigeria face some of the highest maternal mortality risks in the world. We explore the benefits and cost-effectiveness of individual and integrated packages of interventions to prevent pregnancy-related deaths. Methods We adapt a previously validated maternal mortality model to Nigeria. Model outcomes included clinical events, population measures, costs, and cost-effectiveness ratios. Separate models were adapted to Southwest and Northeast zones using survey-based data. Strategies consisted of improving coverage of effective interventions, and could include improved logistics. Results Increasing family planning was the most effective individual intervention to reduce pregnancy-related mortality, was cost saving in the Southwest zone and cost-effective elsewhere, and prevented nearly 1 in 5 abortion-related deaths. However, with a singular focus on family planning and safe abortion, mortality reduction would plateau below MDG 5. Strategies that could prevent 4 out of 5 maternal deaths included an integrated and stepwise approach that includes increased skilled deliveries, facility births, access to antenatal/postpartum care, improved recognition of referral need, transport, and availability quality of EmOC in addition to family planning and safe abortion. The economic benefits of these strategies ranged from being cost-saving to having incremental cost-effectiveness ratios less than $500 per YLS, well below Nigeria’s per capita GDP. Conclusions Early intensive efforts to improve family planning and control of fertility choices, accompanied by a stepwise effort to scale-up capacity for integrated maternal health services over several years, will save lives and provide equal or greater value than many public health interventions we consider among the most cost-effective (e.g., childhood immunization).

Maternal weight gain and pattern of weight gain during pregnancy influence the ultimate outcome of pregnancy. Pregravid body mass index (BMI), maternal dietary intake, maternal height and age all determine the weight gain during pregnancy. The study was taken up with an objective to observe maternal weight gain and its pattern in pregnancy in women from an upper income group and to find out their association with pregnancy outcome. 180 normal primiparous pregnant Indian women (20-35 years) from an upper income group were recruited between the 10th and 14th weeks of pregnancy and were followed up throughout their pregnancy to record total and trimester-wise weight gain. Neonatal birth weights were recorded. The results showed that mothers with high pregravid BMI gained more weight during pregnancy than the recommended weight gain; in addition, weight gain in the first trimester was significantly correlated with birth weight of the neonates (P = 0.019). Significant correlation was found between weight gain in the third trimester and birth weight of the neonate irrespective of maternal BMI. The rate of weight gain was significantly correlated with neonatal birth weights irrespective of maternal pregravid BMI (P = 0.022) and as per its categories (P = 0.027). Thus, overall it can be concluded that adequate maternal nutrition before and during pregnancy is important for adequate weight gain by the mother and can result in better outcome of pregnancy. The rate of weight gain is also an important contributing factor.

The objective of this study was to evaluate the risk of adverse fetal outcome in systemic lupus erythematosus (SLE) women exposed to azathioprine during pregnancy. We reviewed the medical records of SLE pregnant women followed from January 2005 to April 2013. The patients were evaluated at least once in each trimester and postpartum. Relevant fetal outcomes were extracted, such as rate of liveborns, fetal loss (spontaneous abortion and stillbirth), term delivery, preterm birth, neonatal death, low birth weight, low birth weight at term, and congenital malformations. A detailed history of drug use during pregnancy was obtained. We studied 178 pregnancies (in 172 women), 87 of them were exposed to azathioprine (AZA-group) and the remaining 91 were not exposed (NO AZA-group). Exposure to other drugs was similar in both groups. The rate of live births, spontaneous abortions mean birth weight, weeks of gestation, rate of birth weight <2500 g, and low birth weight at term did not differ between groups. No infant had major congenital abnormalities. Multivariate analysis showed that preeclampsia, premature rupture of membranes (PROM), lupus flare, and anti-DNA positive were associated with an increased risk of poor fetal outcome. Our study suggests that the use of azathioprine is safe and lacks of teratogenity in patients with SLE and pregnancy. Exposure to azathioprine during pregnancy is not associated with poor fetal outcome.

Women of childbearing age are often affected with psychotic disorders, requiring the use of antipsychotic medication during pregnancy. In the present study, we prospectively followed the pregnancies of 561 women exposed to second-generation antipsychotic agents (SGAs; study cohort) and compared these to 284 pregnant women exposed to first-generation antipsychotic agents (FGAs; comparison cohort I) and to 1122 pregnant women using drugs known as not harmful to the unborn (comparison cohort II). Subjects were enrolled through the Institute's consultation service. Major malformation rates of SGA exposed were higher compared to comparison cohort II (adjusted odds ratio, 2.17; 95% confidence interval, 1.20-3.91), possibly reflecting a detection bias concerning atrial and ventricular septal defects. Postnatal disorders occurred significantly more often in infants prenatally exposed to SGAs (15.6%) and FGAs (21.6%) compared to 4.2% of comparison cohort II. Cumulative incidences of elective terminations of pregnancy were significantly higher in both the study cohort (17%) and comparison cohort I (21%) compared to comparison cohort II (3%), whereas the rates of spontaneous abortions did not differ. The numbers of stillbirths and neonatal deaths were within the reference range. Preterm birth and low birth weight were more common in infants exposed to FGAs. To conclude, our findings did not reveal a major teratogenic risk for SGAs, making the better studied drugs of this group a treatment option during pregnancy. Because neonates exposed to SGAs or FGAs in the last gestational week are at higher risk of postnatal disorders, delivery should be planned in clinics with neonatal intensive care units.

Mannose-binding lectin (MBL) is a component of the innate immune system and acts as a complement activator through the lectin pathway. Genetic variations of MBL and low MBL levels cause several infection problems, which may also be related to pregnancy problems. We aimed to investigate the role of MBL gene codon 54 polymorphism and serum MBL levels in pregnancy problems and premature delivery. In this prospective study, MBL gene codon 54 polymorphism and serum MBL levels were studied in 45 mothers who delivered earlier than 35 gestational weeks. The frequency of MBL gene codon 54 variant allele B was much higher (homozygous 4.4% and heterozygous 33.3%) in the study group mothers than the previously reported frequency in the healthy Turkish population (homozygous 2-6%, heterozygous 12-20%). MBL variant allele B frequency was closely related to low MBL levels (<0.1 μg/ml), vaginitis and increased IL-6 levels. The median MBL levels were lower than the critical level of 0.1 μg/ ml in study mothers who had recurrent miscarriage, infertility, preeclampsia, gestational diabetes mellitus, preterm premature rupture of membranes with duration of longer than 72 hours, tocolysis, histological chorioamnionitis, urinary tract infection and vaginitis. MBL gene codon 54 variant allele B is related to low serum MBL levels, increased IL-6 levels, genitourinary infections and may cause pregnancy-related problems such as infertility, recurrent miscarriage and preterm delivery.

Polycystic ovary syndrome (PCOS) is a common reproductive disorder associated with many characteristic features, including hyperandrogenaemia, insulin resistance and obesity which may have significant implications for pregnancy outcomes and long-term health of the woman. This meta-analysis was conducted to evaluate the risk of pregnancy and neonatal complications in women with PCOS. Electronic databases were searched for the following MeSH headings: PCOS, hyperandrogenism, pregnancy outcome, pregnancy complications, diabetes mellitus, type II. A handsearch of human reproduction and fertility and sterility was also conducted. Studies in which pregnancy outcomes in women with PCOS were compared with controls were considered for inclusion in this meta-analysis. Fifteen of 525 identified studies were included, involving 720 women presenting with PCOS and 4505 controls. Women with PCOS demonstrated a significantly higher risk of developing gestational diabetes [odds ratio (OR) 2.94; 95% confidence interval (CI): 1.70-5.08], pregnancy-induced hypertension (OR 3.67; 95% CI: 1.98-6.81), pre-eclampsia (OR 3.47; 95% CI: 1.95-6.17) and preterm birth (OR 1.75; 95% CI: 1.16-2.62). Their babies had a significantly higher risk of admission to a neonatal intensive care unit (OR 2.31; 95% CI: 1.25-4.26) and a higher perinatal mortality (OR 3.07; 95% CI: 1.03-9.21), unrelated to multiple births. In conclusion, women with PCOS are at increased risk of pregnancy and neonatal complications. Pre-pregnancy, antenatal and intrapartum care should be aimed at reducing these risks.

The objectives are to report the estimated prevalence of pregnancy complications and adverse pregnancy outcomes in a defined population of Alaska Native women and also examine factors contributing to an intensive and successful collaboration between a tribal health center and the Centers for Disease Control and Prevention. Investigators abstracted medical record data from a random sample of singleton deliveries to residents of the study region occurring between 1997 and 2005. We used descriptive statistics to estimate the prevalence and 95 % confidence intervals of selected pregnancy complications and adverse pregnancy outcomes. Records were examined for 505 pregnancies ending in a singleton delivery to 469 women. Pregnancy complication rates were 5.9 % (95 % CI 4.0, 8.4) for gestational diabetes mellitus, 6.1 % (95 % CI 4.2, 8.6 %) for maternal chronic hypertension and 11.5 % (95 % CI 8.8, 14.6) for pregnancy associated hypertension, and 22.9 % (95 % CI 19.2–26.5 %) for anemia. The cesarean section rate was 5.5 % (95 % CI 3.5, 7.5) and 3.8 % (95 % CI 2.3, 5.8) of newborns weighed >4,500 g. Few previous studies reported pregnancy outcomes among Alaska Native women in a specific geographic region of Alaska and regarding the health needs in this population. We highlight components of our collaboration that contributed to the success of the study. Studies focusing on special populations such as Alaska Native women are feasible and can provide important information on health indicators at the local level. PMID:23775248

Acute kidney injury (AKI) is a rare complication of pregnancy, but may be associated with significant morbidity and mortality in young and often otherwise healthy women. We conducted a retrospective population-based cohort study of all consecutive pregnancies over a 15-year period (1997-2011) in Ontario, Canada, and describe the incidence and outcomes of AKI treated with dialysis during pregnancy or within 12 weeks of delivery. Of 1,918,789 pregnancies, 188 were complicated by AKI treated with dialysis (incidence: 1 per 10,000 [95% confidence interval, 0.8 to 1.1]). Only 21 of 188 (11.2%) women had record of a preexisting medical condition; however, 130 (69.2%) women experienced a major pregnancy-related complication, including preeclampsia, thrombotic microangiopathy, heart failure, sepsis, or postpartum hemorrhage. Eight women died (4.3% versus 0.01% in the general population), and seven (3.9%) women remained dialysis dependent 4 months after delivery. Low birth weight (<2500 g), small for gestational age, or preterm birth (<37 weeks' gestation) were more common in pregnancies in which dialysis was initiated (35.6% versus 14.0%; relative risk, 3.40; 95% confidence interval, 2.52 to 4.58). There were no stillbirths and fewer than five neonatal deaths (<2.7%) in affected pregnancies compared with 0.1% and 0.8%, respectively, in the general population. In conclusion, AKI treated with dialysis during pregnancy is rare and typically occurs in healthy women who acquire a major pregnancy-related medical condition such as preeclampsia. Many affected women and their babies have good short-term outcomes.

Our study sought to determine the characteristics of antenatal patients with tuberculosis (TB) and their pregnancy outcomes. Case records of 50 antenatal women with extra-pulmonary and pulmonary TB at a tertiary centre in India were compared to 150 antenatal women not suffering from TB, for adverse medical, obstetric and neonatal outcomes. The prevalence of TB was 1.16 per 1000 deliveries. Of these, 62% had extra-pulmonary TB. There were two maternal deaths. TB in pregnancy was associated with a five times higher risk of prematurity and three times higher risk of intrauterine growth restriction than the norm. Maternal prognosis depends on the complications of tuberculosis and treatment compliance.

Abstract Aim: The aim of the study is to evaluate the effects of metformin on pregnancy outcomes in women with polycystic ovary syndrome (PCOS). Methods: We searched electronic databases and bibliographies of relevant papers to identify studies comparing the pregnancy outcomes in the metformin group with those in the placebo or blank control group. Then, we did this meta-analysis based on the PRISMA guidelines. The primary outcomes included early pregnancy loss (EPL), preterm delivery, term delivery, and gestational diabetes mellitus (GDM). Secondary outcomes included pregnancy-induced hypertension (PIH), intrauterine growth restriction (IUGR), fetal malformation, vaginal delivery (VD), cesarean section (CS), and metformin's side effects, such as nausea or gastrointestinal discomfort. Certainly, data about neonatal death and macrosomia were analyzed if data available. Results: Finally, 13 studies including 5 randomized controlled trials (RCT) and 8 cohort studies involving 1606 pregnant women with PCOS were analyzed. The pooled OR of EPL was 0.19 with obvious statistical significance, manifesting that metformin help to lower the rate of EPL (95% CI 0.12–0.28, P < 0.00001). Simultaneously, metformin showed the advantage of reducing the prevalence of preterm delivery (OR 0.37, 95% CI 0.20–0.68, P = 0.002). In addition, metformin could promote term delivery greatly and the pooled OR was 5.23 with sharp statistical difference (95% CI 3.12–8.75, P < 0.00001). Conclusion: Metformin treatment in women with PCOS throughout pregnancy could increase the possibility of term delivery, VD and reduce the risk of EPL, preterm labor, pregnancy complications such as GDM and PIH, with no serious side effects. Moreover, metformin was not teratogenic based on the limited data. So we may recommend metformin treatment for women with PCOS during the whole pregnancy period for it is quite beneficial and safe for both mothers and babies. PMID:27603343

Background Maternal immunization has gained traction as a strategy to diminish maternal and young infant mortality attributable to infectious diseases. Background rates of adverse pregnancy outcomes are crucial to interpret results of clinical trials in Sub-Saharan Africa. Methods We developed a mathematical model that calculates a clinical trial's expected number of neonatal and maternal deaths at an interim safety assessment based on the person-time observed during different risk windows. This model was compared to crude multiplication of the maternal mortality ratio and neonatal mortality rate by the number of live births. Systematic reviews of severe acute maternal morbidity (SAMM), low birth weight (LBW), prematurity, and major congenital malformations (MCM) in Sub-Saharan African countries were also performed. Findings Accounting for the person-time observed during different risk periods yields lower, more conservative estimates of expected maternal and neonatal deaths, particularly at an interim safety evaluation soon after a large number of deliveries. Median incidence of SAMM in 16 reports was 40.7 (IQR: 10.6–73.3) per 1,000 total births, and the most common causes were hemorrhage (34%), dystocia (22%), and severe hypertensive disorders of pregnancy (22%). Proportions of liveborn infants who were LBW (median 13.3%, IQR: 9.9–16.4) or premature (median 15.4%, IQR: 10.6–19.1) were similar across geographic region, study design, and institutional setting. The median incidence of MCM per 1,000 live births was 14.4 (IQR: 5.5–17.6), with the musculoskeletal system comprising 30%. Interpretation Some clinical trials assessing whether maternal immunization can improve pregnancy and young infant outcomes in the developing world have made ethics-based decisions not to use a pure placebo control. Consequently, reliable background rates of adverse pregnancy outcomes are necessary to distinguish between vaccine benefits and safety concerns. Local studies that
Background The District Health Information System was developed in South Africa to collect aggregated routine data from public health facilities. In Amajuba District, KwaZulu-Natal, ward-based data collection has been initiated to facilitate improved responsiveness to community health needs and improve health outcomes and patient satisfaction. Aim To assess the application of the municipal ward-based health data in the decision-making process to improve child health outcomes. Setting The study was conducted in 25 primary health care service sites in Amajuba. Methods A cross-sectional mixed methods’ approach was used. The study population comprised operational managers, professional nurses, ward-based outreach team leaders and supervisors. Quantitative data were collected using a semi-structured questionnaire and analysed using descriptive statistics. Qualitative data were collected using focus group discussions and analysed using thematic analysis. Results Of the 131 respondents, 83 (67.5%) provided targeted child interventions to a certain or a large extent to improve child health outcomes, but only 74 (57.4%) respondents reported using municipal ward-based health data to a certain or large extent in order to inform their decisions. This discrepancy indicates poor utilisation of local health information for decision-making. Conclusion The study showed that municipal ward-based health data are not fully utilised for making informed decisions to improve child health outcomes. It is imperative to inculcate a culture of evidence-informed decisions that leads to provision of targeted interventions in order to mitigate the challenge of scarcity of resources and to improve child health outcomes.

Background. Hypothyroidism and raised thyroid antibody levels have been associated with adverse obstetrical outcomes. Several studies have investigated causal associations, but results have been inconsistent and few studies have reported the effects of thyroxine replacement therapy on pregnancy outcomes in hypothyroid patients. Objective. The primary study objective was to determine the outcome of pregnancies in women diagnosed with overt and subclinical hypothyroidism (SCH) (serum TSH > 2.5 mIU/L) and those with elevated circulating thyroid autoantibody levels in the first trimester of pregnancy and after the institution of appropriate thyroxine replacement therapy to maintain the serum TSH ≤ 2.5 mIU/L. Study Design. This prospective observational study was undertaken between 2013 and 2016. Blood samples were taken from 1025 women at presentation for thyroid stimulating hormone (TSH), anti-thyroglobulin antibodies (TGAb), and thyroid peroxidase antibodies (TPOAb). Those with a TSH > 2.5 mIU/L were treated with thyroxine and managed appropriately to ensure that the TSH was maintained ≤2.5 mIU/L. Outcomes in these patients were compared to those in euthyroid patients. Maternal antenatal complications and perinatal outcomes were recorded. Results. There were a total of 1025 patients of whom 382 (37.5%) were nulliparous. 10.1% had a TSH level > 2.5 mIU/L and 18.2% had at least one raised thyroid antibody level. No differences in adverse outcomes of pregnancy were evident in women treated for SCH or overt hypothyroidism compared to the euthyroid group. There was also no association between raised thyroid antibodies and adverse pregnancy outcomes in either group. Conclusion. There were no adverse outcomes of pregnancy found in pregnant women who had been diagnosed and treated with thyroxine for SCH at the time of presentation when compared to euthyroid patients. There was also no relationship with thyroid antibodies and adverse pregnancy outcomes in the

Background. Hypothyroidism and raised thyroid antibody levels have been associated with adverse obstetrical outcomes. Several studies have investigated causal associations, but results have been inconsistent and few studies have reported the effects of thyroxine replacement therapy on pregnancy outcomes in hypothyroid patients. Objective.

Pharmacologic interventions for traumatic brain injury (TBI) hold promise to improve outcome. The purpose of this study was to determine if the microtubule stabilizing therapeutic paclitaxel used for more than 20 years in chemotherapy would improve outcome after TBI. We assessed neurological outcome in mice that received direct application of paclitaxel to brain injury from controlled cortical impact (CCI). Magnetic resonance imaging was used to assess injury-related morphological changes. Catwalk Gait analysis showed significant improvement in the paclitaxel group on a variety of parameters compared to the saline group. MRI analysis revealed that paclitaxel treatment resulted in significantly reduced edema volume at site-of-injury (11.92 ± 3.0 and 8.86 ± 2.2 mm3 for saline vs. paclitaxel respectively, as determined by T2-weighted analysis; p ≤ 0.05), and significantly increased myelin tissue preservation (9.45 ± 0.4 vs. 8.95 ± 0.3, p ≤ 0.05). Our findings indicate that paclitaxel treatment resulted in improvement of neurological outcome and MR imaging biomarkers of injury. These results could have a significant impact on therapeutic developments to treat traumatic brain injury. PMID:26086366

Maternal smoking during pregnancy (SDP) has been associated with several psychiatric outcomes in the offspring; studies have questioned whether the associations are causal, however. We analyzed all children born in Sweden between 1983 and 2009 to investigate the effect of SDP on multiple indicators of adverse outcomes in three areas: pregnancy outcomes (birth weight, preterm birth and being born small for gestational age), long-term cognitive abilities (low academic achievement and general cognitive ability) and externalizing behaviors (criminal conviction, violent criminal conviction and drug misuse). SDP was associated with all outcomes. Within-family analyses of the pregnancy outcomes were consistent with a causal interpretation as the associations persisted when siblings discordant for SDP were compared. For the cognitive and externalizing outcomes, the results were not consistent with causal effects; when comparing differentially exposed siblings none of the associations remained significant. In quantitative genetic models genetic factors explained the majority of the associations between SDP and cognitive and externalizing outcomes. The results suggest that the associations between SDP in mothers and cognition and externalizing behaviors in their offspring is primarily due to genetic effects that influence the behaviors in both generations.

Plasma volume expansion of more than 1.5 l and sustainable activation of the hemostatic system that results in a steady rise of the fibrinogen/fibrin turnover are contemporary physiological events during normal pregnancy. In contrast, adverse outcome of pregnancy i.e. pre-eclampsia commonly coincide with hemo concentration and over activation of blood coagulation both of which alter blood rheology. On the basis of 4,985 consecutively recorded singleton pregnancies values range of blood rheological parameters in women with normal and complicated outcome of pregnancy at the time of their delivery were compared. Plasma viscosity (pv) was determined using KSPV 1 Fresenius and RBC aggregation (stasis: E0 and low shear: E1) using MA1-Aggregometer; Myrenne. Seventy-nine point four percent (n=3,959) had normal pregnancy outcome and 1,026 with adverse outcome of pregnancy had pre-eclampsia (8.4%; n=423), had newborn with a birth-weight < 2,500 g (9.5%; n=473), had early-birth before week 37 (9.3%; n=464), and/or were diagnosed with intra uterine growth retardation (IUGR) (5.0%; n=250). In women with normal pregnancy outcome mean (+/-SD) of pv was 1.31+/-0.09 mPa s, of E0 was 21.6+/-5.3, and of E1 was 38.4+/-7.9 while in women with adverse outcome means for rheological parameters were statistically significantly different i.e. pv: 1.32+/-0.08 mPa s; p=0.006, E0: 22.1+/-5.5; p=0.002 and E1: 39.5+/-8.5; p=0.0006. Subgroup analysis revealed statistical significant lower pv in women who either had pre term delivery or a low birth-weight child (p<0.005) as compared to women who had normal pregnancy outcome while patients with pre-eclampsia had markedly higher low shear and stasis RBC aggregation (p<0.0001). None of the rheological results at term were correlated with either maternal age (r<0.04), BMI (r<0.09), maternal weight gain until delivery (r<0.04), or fetal outcome such as APGAR-score (r<0.09) art. pH in the umbilical cord (-0.05

Background Hepatic dysfunction during pregnancy places both the mother and the fetus at risk. Investigations which are efficient, cost effective and easily available for prognostication are required to tackle this global problem. We studied the etiologies and evaluated investigations for predictive efficiency. Methods One hundred ninety-seven pregnant women with hepatic dysfunction during pregnancy were identified. All patients were followed up till 8 weeks after termination of pregnancy or death. Clinico-demographic, biochemical and hematological data were collected and analyzed. Results One hundred ninety-seven of 6,122 females had abnormal liver function tests. Pre-eclampsia (57%), eclampsia (19%), HELLP syndrome (8%), viral infection (6%), hyperemesis gravidarum (5%), intrahepatic cholestasis of pregnancy (4%), chronic liver disease (1%) and sepsis were encountered. There were 41 fetal deaths, 42% preterm deliveries, and NICU admission rate was 27%. Five maternal deaths occurred. Maternal anemia, thrombocytopenia, hyperbilirubinemia and coagulopathy were statistically significant in adverse fetal outcomes. Serum bilirubin performed better than INR as a predictor of both maternal and fetal outcomes. Conclusions Hepatic dysfunction during pregnancy is associated with adverse events for both the mother and the fetus and hypertensive disorders remain the major cause. Maternal bilirubin levels and INR have a role in predicting adverse feto-maternal outcome. PMID:28270873

Hyperprolactinemia and prolactinomas cause infertility in significant number of women. But, pregnancy may lead to post-partum remission of hyperprolactinemia. The data on pregnancy and tumor outcome in women with macroprolactinoma conceiving on Cabergoline (CAB) therapy is increasing but still less than with Bromocriptine. We studied the incidence of fetal malformations, hyperprolactinemia and tumor course after gestation in infertile women harboring macroprolactinoma, who conceived on CAB therapy during the year 2005-2015. The cohort was divided into two groups based on the continuation of CAB therapy during gestation (Group A) or not (Group B). Forty-eight pregnancies in 33 women were recorded. CAB was continued throughout gestation in 25 pregnancies (Group A). The incidence of missed abortion (8.3%), still birth (4.2%) and low birth weight (7.7%) were not different in two groups. Neural tube defects were observed in 3 pregnancies (all in Group A). Post-partum, recurrence of hyperprolactinemia was observed in 64.6% and 60.9% (p = 0.8) of women in group A and B, respectively. Cabergoline was restarted after 60% and 60.9% (p = 0.9) pregnancies in the two groups in view of symptomatic hyperprolactinemia and/or persistence of macroadenoma. Post-partum, recurrence of hyperprolactinemia is common in spite of significant tumor reduction in infertile women with macroprolactinoma. Continuation of CAB during gestation does not influence the post-pregnancy recurrence of hyperprolactinemia or tumor remission.

It is well-established that psychological stress promotes immune dysregulation in nonpregnant humans and animals. Stress promotes inflammation, impairs antibody responses to vaccination, slows wound healing, and suppresses cell-mediated immune function. Importantly, the immune system changes substantially to support healthy pregnancy, with attenuation of inflammatory responses and impairment of cell-mediated immunity. This adaptation is postulated to protect the fetus from rejection by the maternal immune system. Thus, stress-induced immune dysregulation during pregnancy has unique implications for both maternal and fetal health, particularly preterm birth. However, very limited research has examined stress-immune relationships in pregnancy. The application of psychoneuroimmunology research models to the perinatal period holds great promise for elucidating biological pathways by which stress may affect adverse pregnancy outcomes, maternal health, and fetal development.

Pregnancy-induced hypertension (PIH) induces maternal and fetal damage, but it can also be the beginning of future metabolic and vascular disorders. The relative risk of chronic hypertension after PIH is between 2.3 and 11, and the likelihood of subsequent development of type 2 diabetes is multiplied by 1.8. Women with prior preeclampsia/eclampsia have a twofold risk of stroke and a higher frequency of arrhythmias and hospitalization due to heart failure. Furthermore, a tenfold greater risk for long-term chronic kidney disease is observed as well. The relative risk of cardiovascular death is 2.1 times higher compared to the group without pregnancy-induced hypertension problems, although the risk is between 4 and 7 times higher in preterm birth associated with gestational hypertension or pre-existing hypertension The postpartum period is a great opportunity to intervene on lifestyle, obesity, make an early diagnosis of chronic hypertension and DM and provide the necessary treatments to prevent cardiovascular complications in women.

Introduction Low birth weight due to preterm delivery or intrauterine growth restriction (IUGR) is the strongest factor contributing to prenatal, neonatal, and postnatal mortality. Maternal–fetal attachment plays a significant role in maternal and fetal health. Health practices performed by the mother during pregnancy constitute one of the factors that may affect neonatal outcomes. The present study was conducted to identify the relationship between maternal–fetal attachment and health practices during pregnancy with neonatal outcomes. Methods This cross-sectional study was conducted on 315 pregnant women with a gestational age of 33–41 weeks who presented to hospitals in Sirjan (Iran) between December 2014 and February 2015. The data collection tools used included the Health Practices in Pregnancy Questionnaire and the Maternal Fetal Attachment Scale. Data were analyzed using IBM-SPSS version 20, focusing on the Pearson product–moment correlation and the logistic regression model. Statistical significance was set to p<0.05. Results The mean score of maternal–fetal attachment was 60.34, and the mean score of health practices was 123.57. The mean birth weight of the neonates was 3052.38 g. Health practices (p<0.05, r=0.11) and maternal-fetal attachment (p<0.01, r=0.23) were positively and significantly correlated with neonatal outcomes. A significant positive relationship was also observed between maternal–fetal attachment and neonatal outcomes. No significant relationships were observed between health practices during pregnancy and neonatal outcomes. Conclusion Maternal-fetal attachment and health practices during pregnancy are positively and significantly correlated with neonatal outcomes. PMID:27648191

We used vital statistics data to examine the effect of the time of entry into prenatal care relative to the gestational age of delivery on pregnancy outcome. Early entry into prenatal care was associated with better outcomes only in women who delivered at 37 through 42 weeks of gestation. We are concerned that the evaluation of the effect of prenatal care using vital statistics data may be questionable because of the problems inherent in the data. PMID:1536367

Perinatal outcomes were compared between 354 twins treated with the Higgins Nutrition Intervention Program and 686 untreated twins. After differing distributions of key confounding variables were adjusted for, the twins in the intervention group weighed an average of 80 g more (P less than 0.06) than the nonintervention twins; their low-birth-weight rate was 25% lower (P less than 0.05) and their very-low-birth-weight rate was almost 50% lower (P less than 0.05). Although the rate of preterm delivery was 30% lower in the intervention group (P less than 0.05), the rates of intrauterine growth retardation were similar in the two groups. Fetal mortality was slightly higher (14 vs 12 per 1000, NS), but early neonatal mortality was fivefold lower (3 vs 19 per 1000, P less than 0.06) in the intervention group. Maternal morbidity was significantly lower (P less than 0.05) in the intervention group. There was a trend towards lower infant morbidity in the intervention group. These results suggest that nutritional intervention can significantly improve twin-pregnancy outcome.

The articles appearing in this special section discuss the role that conscientiousness may play in healthy aging. Growing evidence suggests that conscientious individuals live longer and healthier lives. However, the question remains whether this personality trait can be leveraged to improve long-term health outcomes. We argue that even though it may be possible to design therapeutic interventions that increase conscientiousness, there may be more effective and efficient ways to improve population health. We ask for evidence that a focus on conscientiousness improves behavior change efforts that target specific health-related behaviors or large-scale environmental modification.

Gender is known to influence pregnancy outcomes. Recent studies have reported an association between air pollution exposure and adverse pregnancy outcomes, but gender differences have not been considered. In order to assess the current evidence of the interactive effects between gender and air pollution on pregnancy outcomes we undertook a systematic literature review. Using a comprehensive list of keywords, English language articles published between 1966 and 2005 were retrieved from major databases. Additional information on gender was obtained from the study authors. Studies were included if they contained well-defined measurements of ambient air pollutants, investigated pregnancy outcomes and reported estimates by gender. In total 11 studies were included. The quality of the studies was assessed using the framework in Systematic Reviews in Health Care Meta-analysis in context and Bracken's Guidelines. Of the 11 studies, four evaluated low birth weight (LBW); one each evaluated very low birth weight and fetal growth and six examined preterm birth (PTB). Females were at higher risk of LBW: adjusted odds ratios (AOR) ranged from 1.07 to 1.62. Males were at higher risk for PTB: AORs ranged from 1.11 to 1.20. In addition, there was some evidence to suggest that the effect of air pollution on LBW is differential by gender; however, the evidence was available only from four studies. This is the first systematic review to consider gender effect. Further high quality studies are needed to establish whether these findings prevail.

The purpose of this study was to evaluate the predictors of pregnancy outcome for infertile couples attending in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) programmes. Infertile couples attending IVF or ICSI procedures were included in this study. Related data including semen parameters and male and female age and body mass index were collected and analysed. The main outcome was clinical pregnancy, defined as an ultrasound detection of foetal heartbeat 6 weeks after embryo transfer. A total of 1316 couples who underwent IVF and 266 who underwent ICSI were recruited for this study. A multivariate logistic regression with likelihood ratio test revealed the following predictors of pregnancy outcome: female age and sperm DNA fragmentation index (DFI) and acrosomal activity in IVF procedures (chi-square of likelihood ratio = 26.42, d.f. = 3, P < 0.005) and female age and DFI in ICSI procedures (chi-square of likelihood ratio = 18.88, d.f. = 2, P < 0.005). In conclusion, our study indicated that sperm DFI, female age and acrosomal levels have a significant effect on ART pregnancy outcome.

This observational study was carried out to identify the various types of high risk pregnancy and to determine the maternal and foetal outcome. The study was carried out on 206 pregnant high risk women in the Gynecology and Obstetrics department of Border Guard Hospital, Dhaka from January 2012 to December 2012. During mentioned period among 598 pregnant women 206 high risk pregnancy cases were randomly selected. Pregnant women (gestational age from 34 weeks upto 40 weeks) having medical condition and pregnancy related high risk factors were included and uncomplicated pregnancy, pregnancy before 37 weeks, post dated pregnancy were excluded from this study. Data was collected from semi structured history sheet and data analysis done by percentage. High risk pregnant women were grouped into three. Group A and Group B includes pregnant women having medical condition before and during pregnancy respectively. Group C consists of pregnant women had pregnancy related high risk issues. Among 206 high risk pregnancy cases majority 47.57% women had medical condition during pregnancy, 31.55% patient had medical condition before pregnancy. Among them majority 30.58% of the patient suffered from pregnancy induced hypertension, 15.04% patients suffered from gestational Diabetes Mellitus and premature rupture of membranes were 12.13%. In this study majority 43.68% of high risk pregnant patients were in age group of 30-35 years, 19.90% pregnant women were in age group of >35 years and 19.40% were in age group of upto 20 years. Among study groups maximum 65.04% of the patients were multiparous. Among 206 study population 60.19% high risk pregnant women were at term at the time of delivery and 39.8% women delivered their babies preterm. Caesarean section was done in 69.41% of high risk pregnant women. After delivery majority 77.66% women had no complication, only 10.19%, 8.25%, 2.91% and 0.97% high risk pregnant women suffered from fever, UTI, abdominal wound infection and post

Pregnancy in Cushing's syndrome (CS) is extremely rare due to the influence of hypercortisolism on the reproductive axis. Purpose of this study is to investigate whether the etiology of CS in pregnancy determines a different impact on the fetal/newborn and maternal outcomes. We performed a systematic review of cases published in the literature from January 1952 to April 2015 including the words "Cushing AND pregnancy". We included 168 manuscripts containing 220 patients and 263 pregnancies with active CS during pregnancy and with a history of CS but treated and cured hypercortisolism at the time of gestation. Adrenal adenoma was the main cause of active CS during pregnancy (44.1 %). Women with active CS had more gestational diabetes mellitus (36.9 vs. 2.3 %, p = 0.003), gestational hypertension (40.5 vs. 2.3 %, p < 0.001) and preeclampsia (26.3 vs. 2.3 %, p = 0.001) than those with cured disease. The proportion of fetal loss in active CS was higher than in cured CS (23.6 vs. 8.5 %, p = 0.021), as well as global fetal morbidity (33.3 vs. 4.9 %, p < 0.001). The predictors of fetal loss in active CS were etiology of hypercortisolism [Odds Ratio -OR-for pregnancy-induced CS 4.7 (95 % Confidence Interval-CI 1.16-18.96), p = 0.03], publication period [OR for "1975-1994" 0.10 (95 % CI 0.03-0.40), p = 0.001] and treatment during gestation (p = 0.037, [OR medical treatment 0.25 (95 % CI 0.06-1.02), p = 0.052], [OR surgical treatment 0.34 (95 % CI 0.11-1.06), p = 0.063]). The period of diagnosis of CS (before, during or after pregnancy) was the only predictor of overall fetal morbimortality [OR for diagnosis during pregnancy 4.66 (95 % CI 1.37-15.83), p = 0.014]. Patients with active CS, especially in pregnancy-induced CS, experienced more problems in pregnancy and had the worst fetal prognosis in comparison to other causes. Diagnosis of CS during pregnancy was also associated with worse overall fetal

Background We aimed to compare reproductive outcomes following ectopic pregnancy (EP) versus livebirth, miscarriage, or termination in a first pregnancy. Methods And Findings A retrospective cohort study design was used. Scottish national data on all women whose first pregnancy occurred between 1981 and 2000 were linked to records of a subsequent pregnancy. The exposed cohort comprised women with an EP in their first pregnancy. There were three unexposed cohorts: women with livebirth, miscarriage, and termination of their first pregnancies. Any differences in rates of second pregnancy, livebirth, EP, miscarriage, or terminations and complications of a second ongoing pregnancy and delivery were assessed among the different exposure groups. A total of 2,969 women had an initial EP; 667,299 had a livebirth, 39,705 women miscarried, and 78,697 terminated their first pregnancies. Women with an initial EP had an increased chance of another pregnancy within 2 years (adjusted hazard ratio (AHR) 2.76 [95% CI 2.58–2.95]) or after 6 years (AHR 1.57 [95% CI 1.29–1.91]) compared to women with a livebirth. In comparison with women with an initial miscarriage, women who had an EP had a lower chance of a second pregnancy (AHR 0.53 [95% CI 0.50–0.56]). Compared to women with an initial termination, women with an EP had an increased chance of a second pregnancy (AHR 2.38 [95% CI 2.23–2.55]) within 2 years. Women with an initial EP suffered an increased risk of another EP compared to women with a livebirth (AHR 13.0 [95% CI 11.63–16.86]), miscarriage (AHR 6.07 [95% CI 4.83–7.62]), or termination (AHR 12.84 [95% CI 10.07–16.37]). Perinatal complications in a pregnancy following EP were not significantly higher than those in primigravidae or in women with a previous miscarriage or termination. Conclusion Women with an initial EP have a lower chance of conception than those who miscarry but an increased risk of a repeat EP in comparison with all three comparison groups. A

Schizophrenia in the mother may imply an increased risk of adverse pregnancy outcome. However, inconclusive findings, unknown pathological mechanisms and possible confounding by social factors and smoking requests further explorations. The aim of this study were to (1) examine non-optimal pregnancy outcome using data from a population-based cohort, controlling for covariates known to influence fetal growth; and (2) perform separate analyses of women diagnosed before childbirth and women hospitalized for schizophrenia during pregnancy. The study sample comprised 2096 births by 1438 mothers diagnosed with schizophrenia (of whom 696 mothers were antenatal diagnosed and 188 admitted during pregnancy) and 1,555,975 births in the general population. We found significantly increased risks for stillbirth, infant death, preterm delivery, low birth weight, and small-for-gestational-age among the offspring of women with schizophrenia. Women with an episode of schizophrenia during pregnancy had the highest risks (e.g., low birth weight; OR 4.3, 95% CI 2.9-6.6 and stillbirth; OR 4.4, 95% CI 1.4-13.8). Controlling for a high incidence of smoking during pregnancy among schizophrenic women (51% vs. 24% in the normal population) and other maternal factors (single motherhood, maternal age, parity, maternal education, mothers' country of birth and pregnancy-induced hypertensive diseases) in a multiple regression model, reduced the risk estimates markedly. However, the risks for adverse pregnancy outcomes were even after adjustments generally doubled for women with an episode of schizophrenia during pregnancy compared to women in the control group (e.g., low birth weight; OR 2.3, 95% CI 1.5-3.5, preterm delivery; OR 2.4, 95% CI 1.5-3.8 and stillbirth; OR 2.5, 95% CI 0.8-7.9). The risks for preterm delivery and low birth weight were significantly elevated throughout the analyses. We conclude that schizophrenia in the mother implies an increased risk for poor perinatal outcome, not

Much has been written about the consequences of substance use in pregnancy, but there has been far less focus on the prevention of unintended pregnancies in women with substance use disorders (SUDs). We examine the literature on pregnancy incidence for women with SUDs, the clinical and economic benefits of increasing access to long-acting reversible contraceptive (LARC) methods in this population, and the current hurdles to increased access and uptake. High rates of unintended pregnancies and poor physical and psychosocial outcomes among women with SUDs underscore the need for increased access to, and uptake of, LARC methods among these women. A small number of studies that focused on improving access to contraception, especially LARC, via integrated contraception services predominantly provided in drug treatment programs were identified. However, a number of barriers remain, highlighting that much more research is needed in this area. PMID:27199563

Oxidative stress in utero-placental tissues plays an important role in the development of placental-related diseases. Maternal hiperhomocysteinemia is associated with placental mediated diseases, such as preeclampsia, spontaneous abortion and placental abruption. The aim of our study is to appreciate the clinical usefulness of the dosage serum homocysteine and malondialdehyde, as an oxidative stress marker, in the pregnancies complicated with risk of abortion or preterm birth. The study was performed at the Obstetric Gynecology Clinical Hospital Oradea from December 2009 until April 2010. It included 18 patients with risk of abortion (group 1), 22 with preterm birth (group 2). The results were compared with a control group composed by 14 healthy pregnant women. Serum homocysteine level was measured by an enzymatic method, on the instrument Hitachi 912, Roche, reagent: Axis-Shield Enzymatic. For proving the oxidative stress we established the level of malondialdehyde using a method with thiobarbituric acid TBA (Kei Satoh 1978) and the level of ceruloplasmin with the Ravin method .Also AST, ALT,CRP, iron, uric acid, urea were assessed.High level of homocysteine in both groups of study in comparison with the control group was found. The concentration of MDA was significantly higher in pregnancies complicated with risk of abortion and preterm birth compared to the control group (p=0.040, p=0.031). Considerable differences of ceruloplasmin concentration between group 1 and group 2 (p=0.045), and between group 2 and control group (p=0.034), was noticed but not any important differences between group 1 and control group (p=0.683). In women with risk of abortion or with preterm birth an oxidative stress and a hyperhomocysteinemia are present.

Background: The aim of this study was to investigate the relationship between idiopathic microscopic hematuria (in the first and second trimesters) and major adverse outcomes of pregnancy. Materials and Methods: Urinalysis was done for 700 pregnant women before 24 weeks of pregnancy. Those who had 3–5 red blood cells per milliliter in urinalysis were considered positive urinalysis. Then, all individuals were examined for blood pressure and other alarm signs of pregnancy complications in each visit. All mothers were followed for the incidence of preeclampsia, preterm delivery, and pregnancy outcome until the end of pregnancy. Results: The results of this study showed that no significant difference in terms of incident of pregnancy complications between the pregnant women with and without hematuria and the only abortions and neonatal deaths differed between the two groups. Conclusion: These results suggest that further studies are needed to determine whether idiopathic microscopic hematuria can be a predictive value for pregnancy complications or not. PMID:28028526

with JOMIVA balloon. Post procedure mean mitral valve area was 1.7 cm2 as assessed by echocardiography. Post procedure mean gradient across the mitral valve as assessed by echocardiography was 5 mmHg. Two patients had moderate to severe mitral regurgitation after the procedure and the rest had either no mitral regurgitation or mild mitral regurgitation after the procedure. None of the patients warranted mitral valve replacement after BMV. No patients had any manifestations of systemic embolism like cerebrovascular accident or limb ischemia after the procedure. None of the patients had preterm delivery or adverse fetal outcome during index hospitalisation. Conclusion Over the wire BMV is safe and effective method during pregnancy. The results are comparable to that of Inoue technique. BMV offers a good symptomatic improvement in pregnant women presenting with symptoms of pulmonary congestion because of Rheumatic mitral stenosis. PMID:28384909

There is a paucity of data regarding the outcome of pregnancy from the Indian subcontinent. Therefore, we decided to analyse the outcome of pregnancy in our cohort of mothers with systemic lupus erythematosus (SLE). Data regarding pregnancies after onset of disease in patients with SLE was analysed in terms of number of pregnancies, effect of pregnancy on disease activity and effect of disease such as organ involvement, presence of anticardiolipin and anti-Ro antibodies, on the outcome of pregnancy. Fifty-two pregnancies occurred in 31 patients. Thirty-one and 21 pregnancies occurred when the disease was inactive and active, respectively. Excluding the 11 induced abortions, the live birth rate was 82.6% in the inactive group and 27.7% in the active group. Foetal loss was mainly due to 12 spontaneous abortions. There were three stillbirths and two neonatal deaths. Disease flare occurred only in the active group, one during pregnancy and two post-partum, one of which resulted in the death of the patient. The presence of antibodies to cardiolipin and to Ro/La was not associated with adverse outcome. Thus, the live birth rate in developing countries in SLE mothers is worse compared with developed countries. Active disease during pregnancy is significantly associated with increased foetal loss.

Objectives One of Africa's most important challenges is to improve maternal and neonatal health. The identification of groups at highest risk for adverse pregnancy outcomes is important for developing and implementing targeted prevention programmes. This study assessed whether young adolescent girls constitute a group at increased risk for adverse birth outcomes among pregnant women in sub-Saharan Africa. Setting Data were collected prospectively as part of a large randomised controlled clinical trial evaluating intermittent preventive treatment of malaria in pregnancy (NCT00811421—Clinical Trials.gov), conducted between September 2009 and December 2013 in Benin, Gabon, Mozambique and Tanzania. Participants Of 4749 participants, pregnancy outcomes were collected for 4388 deliveries with 4183 live births including 83 multiple gestations. Of 4100 mothers with a singleton live birth delivery, 24% (975/4100) were adolescents (≤19 years of age) and 6% (248/4100) were aged ≤16 years. Primary and secondary outcome measures Primary outcomes of this predefined analysis were preterm delivery and low birth weight. Results The overall prevalence of low birthweight infants and preterm delivery was 10% (371/3851) and 4% (159/3862), respectively. Mothers aged ≤16 years showed higher risk for the delivery of a low birthweight infant (OR: 1.96; 95% CI 1.35 to 2.83). Similarly, preterm delivery was associated with young maternal age (≤16 years; OR: 2.62; 95% CI 1.59 to 4.30). In a subanalysis restricted to primiparous women: preterm delivery, OR 4.28; 95% CI 2.05 to 8.93; low birth weight, OR: 1.29; 95% CI 0.82 to 2.01. Conclusions Young maternal age increases the risk for adverse pregnancy outcomes and it is a stronger predictor for low birth weight and preterm delivery than other established risk factors in sub-Saharan Africa. This finding highlights the need to improve adolescent reproductive health in sub-Saharan Africa. Trial registration number NCT00811421

Acute viral myocarditis may impair prognosis in children of all ages. Its true incidence is underestimated because of heterogeneity of presentation and outcome. Patients may either recover or progress to chronic cardiomyopathy or death. Improving short-term and long-term prognosis is challenging but can probably be achieved by new diagnostic techniques and novel targeted therapies. The objectives of this review are: (1) to detail the current state of knowledge of the pathophysiological mechanisms of acute myocarditis; (2) to provide an update on diagnostic tools such as magnetic resonance imaging and endomyocardial biopsy; and (3) to present new insights in therapeutic strategies, targeted therapies and management of fulminant cases. Options for improving outcomes in acute myocarditis in the pediatric population are discussed.

Certain gene polymorphisms are associated with implantation failure and pregnancy loss. Studies of leukaemia inhibitory factor (LIF) gene polymorphisms are scarce. The LIF single nucleotide polymorphism (SNP) thymine (T)/guanine (G) (rs929271) was studied in women to determine whether an association existed with pregnancy outcomes after intracytoplasmic sperm injection (ICSI); 411 women who underwent ICSI were recruited. DNA was extracted from the peripheral blood, and the LIF gene SNP T/G (rs929271) was genotyped using real-time polymerase chain reaction. Participants were divided into three groups according to their LIF genotype: T/T (n = 168), T/G (n = 202) and G/G (n = 41). All IVF and ICSI procedures were carried out under the same clinical and laboratory conditions. The ICSI cumulative results (from fresh plus frozen cycles) of each genotype group were analysed. The G/G genotype in women was associated with a higher implantation rate (T/T: 15.9%, T/G: 16.2%, G/G: 27.0%; P < 0.05), ongoing pregnancy rate/patient (T/T: 31.5%, T/G: 36.1%, G/G: 53.7%; P < 0.05) and ongoing pregnancy rate/transfer (T/T: 18.5%, T/G: 20.2%, G/G: 36.7%; P < 0.05). LIF SNP T/G (rs929271) seems to be a susceptibility biomarker capable of predicting implantation efficiency and pregnancy outcomes.

Objectives The objective of this study is to describe the maternal characteristics, pregnancy complications, and birth outcomes among a representative sample of Rhode Island women with disabilities who recently gave birth. Methods Data from the 2002–2011 Rhode Island Pregnancy Risk Assessment Monitoring System (PRAMS) survey were analyzed. Results Approximately 7% of women in Rhode Island reported a disability. Women with disabilities reported significant disparities in their health care utilization, health behaviors and health status before and during pregnancy and during the postpartum period. Compared to nondisabled women, they were significantly more likely to report stressful life events and medical complications during their most recent pregnancy, were less likely to receive prenatal care in the first trimester, and more likely to have preterm births (13.4%; 95% CI, 11.6–15.6 compared to 8.9%; 95% CI, 8.5–9.3 for women without disabilities) and low birth weight babies (10.3%; 95% CI, 9.4–11.2 compared to 6.8%; 95% CI, 6.8–6.9). There was no difference in the rates of cesarean section between women with and without disabilities. Conclusion These findings support the need for clinicians providing care to pregnant women with disabilities to be aware of the increased risk for medical problems during pregnancy and factors that increase the risk for poor infant outcomes.

Concern for exposures to drinking water contaminants and their effects on adverse birth outcomes has prompted several studies evaluating chlorination disinfection by-products and chlorinated solvents. Some of these contaminants are found to be teratogenic in animal studies. This review evaluates 14 studies on chlorination disinfection by-products such as trihalomethanes (THMs) and five studies on chlorinated solvents such as trichloroethylene (TCE). The adverse birth outcomes discussed in this review include small for gestational age (SGA), low birth weight, preterm birth, birth defects, spontaneous abortions, and fetal deaths. Because of heterogeneities across the studies in the characterization of birth outcomes, the assessment and categorization of exposures, and the levels and mixtures of contaminants, a qualitative review was conducted. Generally, the chief bias in these studies was exposure misclassification that most likely underestimated the risk, as well as distorted exposure-response relationships. The general lack of confounding bias by risk factors resulted from these factors not being associated with drinking water exposures. The studies of THMs and adverse birth outcomes provide moderate evidence for associations with SGA, neural tube defects (NTDs), and spontaneous abortions. Because fewer studies have been conducted for the chlorinated solvents than for THMs, the evidence for associations is less clear. Nevertheless, the findings of excess NTDs, oral clefts, cardiac defects, and choanal atresia in studies that evaluated TCE-contaminated drinking water deserve follow-up. PMID:11834464

Pregnancy is associated with major physiological and future psychosocial changes, and maternal adaptation to these changes is crucial for normal foetal development. Psychological stress in pregnancy predicts an earlier birth and lower birth weight. Pregnancy-specific stress contributes directly to preterm delivery. The importance of nutrition and exercise during pregnancy with regard to pregnancy outcome has long been acknowledged. This importance has only been further emphasized by the recent changes in food quality and availability, lifestyle changes and a new understanding of foetal programming's effects on adult outcomes. We hypothesised that for a successful pregnancy certain events at a nutritional, immune, psycho-emotional and genetic level should be tightly linked. Therefore, in this study we followed an 'integrative' approach to investigate how maternal stress, nutrition, pregnancy planning and exercise influence pregnancy outcome. A key finding of our study is that there was a significant reduction in the intake of alcohol, caffeine-containing and sugary drinks during pregnancy. However, passive smoking in the household remained unchanged. In terms of immune profile, a significant inverse correlation was noted between difficulty to 'fight' an infection and number of colds (r=-0.289, P=0.003) as well as the number of infections (r=-0.446, P<0.0001) during pregnancy. The vast majority of the pregnant women acquired a more sedentary lifestyle in the third trimester. In planned, but not in unplanned, pregnancies stress predicted infant weight, independent of age and body mass index (BMI). Notably, in mothers with negative attitudes towards the pregnancy, those with an unplanned pregnancy gave birth to infants with significantly higher weights than those with planned pregnancies. Collectively these data suggest that there is a higher order of complexity, possibly involving gene-environment interactions that work together to ensure a positive outcome for the

Objective The aim of the present study was to evaluate the single and joint associations of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) with pregnancy outcomes in Tianjin, China. Methods Between June 2009 and May 2011, health care records of 33,973 pregnant women were collected and their children were measured for birth weight and birth length. The independent and joint associations of prepregnancy BMI and GWG based on the Institute of Medicine (IOM) guidelines with the risks of pregnancy and neonatal outcomes were examined by using Logistic Regression. Results After adjustment for all confounding factors, maternal prepregnancy BMI was positively associated with risks of gestational diabetes mellitus (GDM), pregnancy-induced hypertension, caesarean delivery, preterm delivery, large-for-gestational age infant (LGA), and macrosomia, and inversely associated with risks of small-for-gestational age infant (SGA) and low birth weight. Maternal excessive GWG was associated with increased risks of pregnancy-induced hypertension, caesarean delivery, LGA, and macrosomia, and decreased risks of preterm delivery, SGA, and low birth weight. Maternal inadequate GWG was associated with increased risks of preterm delivery and SGA, and decreased risks of LGA and macrosomia, compared with maternal adequate GWG. Women with both prepregnancy obesity and excessive GWG had 2.2–5.9 folds higher risks of GDM, pregnancy-induced hypertension, caesarean delivery, LGA, and macrosomia compared with women with normal prepregnancy BMI and adequate GWG. Conclusions Maternal prepregnancy obesity and excessive GWG were associated with greater risks of pregnancy-induced hypertension, caesarean delivery, and greater infant size at birth. Health care providers should inform women to start the pregnancy with a BMI in the normal weight category and limit their GWG to the range specified for their prepregnancy BMI. PMID:24376527

The objective of this study was to investigate the determining effects of diagnosis time on pregnancy outcomes in a population of pregnant women with idiopathic thrombocytopenic purpura (ITP). Records of all the pregnant women with thrombocytopenia were evaluated. Those with a confirmed diagnosis of ITP were included in the study. Main outcome measures were antenatal thrombocyte count, postpartum haemorrhage rate, and route of delivery. Foetal outcomes such as foetal thrombocyte count, haemorrhage, and birth weight were also reported as secondary outcome measures. Time of diagnosis either antenatal or preconception did not significantly alter the investigated parameters. Delivery route had no impact on complication rates. Time of diagnosis also did not affect treatment modality. ITP is rare disorder accounting for less than 5 % of all pregnant thrombocytopenias. Time of diagnosis does not affect maternal-foetal outcomes or treatment modality unless diagnosis is made during labour. Compared to gestational thrombocytopenia, treatment rates may differ but treatment modalities remain the same and the effort put into making the differential should be weighed against maternal stress factors for lengthy laboratory evaluation as long as the thrombocytopenia is of pure nature without any systemic involvement.

Introduction: Delayed childbearing is increasing, and advanced maternal age has been associated with an increased risk of obstetrical complications. The purpose of this study was to evaluate pregnancy outcomes in women with advanced maternal age (≥ 40 years). Methods: Maternal and obstetrical data were collected from the Department of Obstetrics and Gynecology of the University of Wuerzburg for the period from 2006 to 2011. In this retrospective analysis we compared the outcomes for women aged ≥ 40 years (n = 405) with those of three younger subgroups (I: < 30 y; II: 30–34 y; III: 35–39 y). Results: Pregnant women older than 40 years had more chronic diseases such as hypertension, needed medical treatment more frequently and had a higher thrombosis risk. Pregnancy-induced diseases such as gestational diabetes, preeclampsia and pregnancy-associated hypertension occurred more often in women ≥ 40 years of age. Compared to mothers who were younger than 30 years, primiparous women ≥ 40 years had a more than four times higher overall cesarean section rate and four times higher elective cesarean section rate. Furthermore, they required longer hospital stays, both after cesarean section and after vaginal delivery. The preterm birth rate (≤ 32 weeks of gestation) was similar across the different age groups. Conclusions: The outcomes of pregnancy and childbirth and for newborns born to women ≥ 40 years did not vary significantly from those of younger women if the following conditions were met: a) pre-existing chronic diseases were treated medically and dietetically; b) pregnancy-induced morbidity was monitored regularly and controlled medically; c) women attended regular prenatal check-ups; d) a healthy lifestyle was adhered to during pregnancy, and e) delivery occurred in a perinatal center.

Fluoroquinolones are avoided during pregnancy due to developmental toxicity in animals. The aim of this study was to assess the fetal risk after intrauterine fluoroquinolone exposure. We performed an observational study of a prospectively ascertained cohort of pregnant women exposed to a fluoroquinolone during the first trimester. Pregnancy outcomes were compared to those of a cohort exposed to neither fluoroquinolones nor teratogenic or fetotoxic drugs. The outcomes evaluated were major birth defects (structural abnormalities of medical, surgical, or cosmetic relevance), spontaneous abortion, and elective termination of pregnancy. Pregnancy outcomes of 949 women with fluoroquinolone treatment were compared with those of 3,796 nonexposed controls. Neither the rate of major birth defects (2.4%; adjusted odds ratio [ORadj], 0.91; 95% confidence interval [CI], 0.6 to 1.5) nor the risk of spontaneous abortion (adjusted hazard ratio [HRadj], 1.01; 95% CI, 0.8 to 1.3) was increased. However, there was a nonsignificant increase in major birth defects after exposure to moxifloxacin (6/93, 6.5%; crude odds ratio [ORcrude], 2.40; 95% CI, 0.8 to 5.6). Neither a critical exposure time window within the first trimester nor a specific pattern of birth defects was demonstrated for any of the fluoroquinolones. The rate of electively terminated pregnancies was increased among the fluoroquinolone-exposed women (HRadj, 1.32; 95% CI, 1.03 to 1.7). The gestational ages at delivery and birth weights did not differ between groups. Our study did not detect an increased risk of spontaneous abortion or major birth defects. These reassuring findings support the recommendation to allow fluoroquinolone use in early pregnancy in selected cases. After the use of moxifloxacin, a detailed fetal ultrasound examination should be considered. PMID:24841264

Reliance on self-reported smoking status among pregnant women can result in exposure misclassification. We used data from the Calcium for Preeclampsia Prevention trial, a randomized study of nulliparous women conducted from 1992 to 1995, to characterize tobacco exposure misclassification among women who reported at study enrollment that they had quit smoking. Urinary cotinine concentration was used to validate quit status, and factors associated with exposure misclassification and the effects of misclassification on associations between smoking and pregnancy outcomes were evaluated using logistic regression. Of 4,289 women enrolled, 508 were self-reported smokers and 771 were self-reported quitters. Of 737 self-reported quitters with a valid cotinine measurement, 21.6% had evidence of active smoking and were reclassified as smokers. Women who reported having quit smoking during pregnancy were more likely to be reclassified than women who reported quitting before pregnancy (p<.001). Among smokers, factors independently associated with misclassification of smoking status included fewer cigarettes smoked per day and fewer years smoked. After reclassification the odds ratio for a small-for-gestational-age birth among smokers decreased by 14%, and the smoking-related reduction in birth weight decreased by 15%. Effects of misclassification on the association with hypertensive disorders of pregnancy were present but less dramatic. In conclusion, use of self-reported smoking status collected at the time of study enrollment resulted in the introduction of bias into our study of smoking and pregnancy outcomes. The potential for this type of bias should be considered when conducting and interpreting epidemiologic studies of smoking and pregnancy outcomes.

Animal evidence suggests an association between exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and adverse pregnancy outcomes. Epidemiologic studies report inconsistent results, but are limited by narrow range of exposure, small sample size, and lack of a biologic measure of highest lifetime exposure. On July 10, 1976, a chemical explosion in Seveso, Italy resulted in the highest known residential exposure to TCDD. In 1996, we initiated the Seveso Women's Health Study (SWHS), a retrospective cohort of TCDD exposure and reproductive health. Individual-level TCDD was measured in serum collected soon after the explosion. After 20years of follow-up, we found no association between maternal TCDD in 1976 serum or estimated at pregnancy and spontaneous abortion (SAB), fetal growth, or gestational length. Here, we present an updated analysis of TCDD exposure and adverse pregnancy outcomes from a subsequent follow-up of the SWHS cohort in 2008-2009. SWHS women had 1211 post-explosion pregnancies through the 2008-2009 follow-up. We found no association between TCDD estimated at pregnancy and SAB, fetal growth, or gestational length. However, we found a non-significant inverse association between maternal 1976 serum TCDD and birthweight (adjusted β=-22.8, 95% CI: -80.1, 34.6). The association was stronger among first post-explosion births, but remained non-significant (adjusted β=-47.7, 95% CI: -107.3, 11.9). SWHS is the first study to be able to consider two potentially relevant measures of TCDD exposure: highest lifetime dose and in utero. Our results, although non-significant, suggest that highest dose may be more relevant in epidemiologic studies of TCDD and pregnancy outcomes.

As consumptive extractions and water scarcity pressures brought about by climate change increase in many world river basins, so do the risks to water-dependent ecological assets. In response, public or not for profit environmental water holders (EWHs) have been established in many areas and bestowed with endowments of water and mandates to manage water for ecological outcomes. Water scarcity has also increasingly spawned water trade arrangements in many river basins, and in many instances, EWHs are now operating in water markets. A number of EWHs, especially in Australia, begin with an endowment of permanent water entitlements purchased from irrigators. Such water entitlements typically have relatively constant interannual supply profiles that often do not match ecological water demand involving flood pulses and periods of drying. This article develops a hydrologic-economic simulation model of the Murrumbidgee catchment within the Murray-Darling Basin to assess the scope of possibilities to improve environmental outcomes through EWH trading on an annual water lease market. We find that there are some modest opportunities for EWHs to improve environmental outcomes through water trade. The best opportunities occur in periods of drought and for ecological outcomes that benefit from moderately large floods. We also assess the extent to which EWH trading in annual water leases may create pecuniary externalities via bidding up or down the water lease prices faced by irrigators. Environmental water trading is found to have relatively small impacts on water market price outcomes. Overall our results suggest that the benefits of developing EWH trading may well justify the costs.

There is increasing evidence that green space can improve the health and well-being of urban residents. However, there has been no consistent evidence of the effect of city parks on reproductive health. We investigated whether surrounding greenness levels and/or distance to city parks affect birth outcomes. This study was based on 3292 singleton live-births from the Kaunas birth cohort, Lithuania (2007-2009), who were enrolled in the FP7 PHENOTYPE project study. Residential surrounding greenness level was ascertained as average of satellite-based normalized difference vegetation index (NDVI) within buffers of 100 m, 300 m, and 500 m of each maternal home and distance to a city park was defined as distance to boundaries of the nearest city park. For each indicator of green space exposure, linear or logistic regression models were constructed to estimate change in birth outcomes adjusted for relevant covariates. An increase in distance to a city parks was associated with an increase in risk of preterm birth and decrease of gestational age. We found a statistically significant association between low surrounding greenness and term low birth weight. After assessing effect modification based on the low surrounding greenness (NDVI-500

The purpose of the study was to investigate whether proximity to nuclear power plants may increase the risk of abnormal pregnant outcomes among the resident women. In this ecological study, data were used from the Health Services Birth Reports Database established by the Bureau of Health Promotion, National Department of Health, Taiwan, in 2001-2004. Chi-square-tests were carried out to investigate the "Plant-vicinity" and "Non plant-vicinity" group in terms of pregnancy outcome. Additionally, logistic regression was performed to investigate whether residence in the vicinity of a nuclear power plant was related to any abnormal pregnancy results. Based on data from 5,679 included subjects, no difference was observed between pregnancy outcomes of the "Plant-vicinity" and "Non plant-vicinity" groups. After accounting for possible confounders, the adjusted odds ratios were 1.20 (95% CI = 0.56-2.56) for stillbirth, 1.21 (95% CI = 0.95-1.53) for premature birth, 1.04 (95% CI = 0.79-1.37) for low birth weight, and 1.58 (95% CI = 0.85-2.93) for congenital deficiencies, respectively, when comparing the "Plant-vicinity" with the "Non plant-vicinity" group. The results of the study indicate that residence in the vicinity of a nuclear power plant is not a significant factor which will cause abnormal health situations during pregnancy.

To evaluate whether periconceptional exposure to oral contraceptives (OCs) increased adverse pregnancy outcomes, 136 pregnant women taking OCs within the periconceptional period were identified at the Korean Motherisk Program. Of them, 120 pregnant women accepted to participate in their study and were followed up until completion of the pregnancy. A control group of 240 age- and gravidity-matched pregnant women exposed to non-teratogen drugs for at least 1 month before pregnancy was also included. The median gestational age at delivery was 39.1 (27.0-41.0) weeks in the exposed group and 39.3 (27.4-42.0) weeks in the control group (P = 0.19). In the exposed group, 7.1% of babies were born with low birth weight versus 2.6% in the control group (P = 0.068). The number of preterm deliveries or babies born large for gestational age did not differ between the two groups. In the exposed group, the rate of birth defects was 3.2% (n = 3/99) versus 3.6% (n = 7/193) in the control group (P = 1.0). There were 15 women who took high doses of progesterone (emergency contraception) and no adverse fetal outcomes were observed. In conclusion, periconceptional exposure to OCs does not appear to increase the risk for adverse pregnancy outcomes.

AIM: To rule out maternal and pregnancy factors that may contribute to platelet count (PLT) changes in the first trimester of gestation and examine if there is any association between its levels and adverse perinatal outcome. METHODS: The study population included all patients from the first-trimester visit between 2013-2015 with pregnancy results. Linear multiple regression was constructed to rule out variables that may have a significant contribution to PLT. For each adverse outcome at birth, multiple logistic regression analysis was implemented to estimate the PLT effect. RESULTS: PLT was measured in 6092 patients. There was the significant contribution on PLT in the first trimester from maternal weight, the presence of rheumatologic disease, BHCG levels and MPV. There was a significant association between PLT and abnormal cardiotocography at delivery (OR 1.004; IC95% 1.001 to 1.007) and C-Section due to abnormal CTG (OR 1.005; IC95% 1.002 to 1.008). When adjusted for factors that interact with PLT there was also a significant association with pH at birth < 7.10 and gestational diabetes. CONCLUSIONS: Maternal and pregnancy factors can poorly predict relevant changes in PLT at the first trimester of gestation. PLT at first trimester of pregnancy might predict adverse perinatal outcome in combination with other markers. PMID:28293312

Purpose: The aim of this study was to evaluate the pregnancy outcomes in women with Hodgkin lymphoma (HL) diagnosis, treated between 1972 and 1999 at Department of Radiotherapy and Hematology of University 'Sapienza' of Roma. Methods and Materials: We retrospectively studied 99 female patients that conceived after treatment for HL. Fifty-nine (59%) were treated with chemotherapy and radiotherapy, 32 (32%) with radiotherapy alone as supradiaphragmatic or as infradiaphragmatic and 8 (8%) patients with chemotherapy alone. Results: Ninety-nine patients reported 145 pregnancies. We observed 132 deliveries (2 of them twin births) after a median of 55 months (range, 14-278 months) from the end of therapy. Twelve women (12%) experienced 13 miscarriages after a median of 50 months (range, 13-120) from the end of therapy. We recorded 9/132 (7%) premature births and 3/134 babies (2%) were underweight at the time of birth. We recorded 2 cases of congenital malformations. No statistical differences were recorded when adverse pregnancy outcomes were analyzed with respect to chemotherapy alone, radiotherapy alone, or combined therapy. Conclusions: No significant associations between pregnancy outcomes and therapeutic approaches were found. In particular, the infradiaphragmatic radiotherapy showed no statistical association with miscarriages, premature birth, and low birth weight at term when compared with other therapeutic approaches.

The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration.

The effect of illegal abortion on subsequent reproduction was studied in 46 Nigerian women who gave a history of illegal termination of pregnancy. There was a statistically significant increase in the incidences of premature rupture of membranes, premature labour and low birth weight when compared to 53 primigravida who gave no such history of abortion. The perinatal mortality was also significantly higher in the abortion group. In contrast, pre-eclampsia was less common in the abortion group. These findings indicate that illegal abortion has adverse effects on pregnancy outcome in Nigerian women.

Pregnancy associated liver diseases affect up to 3% of pregnant women and are the most frequent cause of liver dysfunction in pregnancy. When severe, they are associated with significant morbidity and mortality for both mother and infant. A rapid evaluation to distinguish them from non-pregnancy related liver dysfunction is essential, in order to facilitate appropriate management. Liver disease unrelated to pregnancy can present de novo in pregnancy, or pregnancy can occur in women with preexisting liver pathology (Table 1). Research and subsequent advances in medical care have resulted in improved but still not satisfactory maternal and fetal outcomes. In this review we provide an overview of the liver diseases specific to the pregnant state and an update on their pathogenesis, treatment and outcomes. The risks of pregnancy in women with pre-existent liver pathology is detailed and recent advances in our understanding of specific risks and outcomes are discussed.

Antiphospholipid syndrome (APS) is associated with pregnancy complications such as recurrent early fetal loss (RFL), fetal death, preeclampsia (PE), and intrauterine growth restriction (obstetric APS/OAPS). Other clinical manifestations are venous and/or arterial thromboses (thrombotic APS/TAPS). The data of 37 pregnancies with OAPS and 37 pregnancies with TAPS were analyzed and compared. Overall, the most frequent APS antibodies (aPl) were LA as well as "triple-positivity"; LA antibodies were significantly more frequent in women with TAPS (67.6 % TAPS vs. 29.7 % OAPS, p < 0.010), whereas "triple-positivity" was significantly more seen in women with OAPS (40.5 % OAPS vs. 13.5 % TAPS, p < 0.010). Adequate therapy has been administered in nearly all pregnancies with TAPS, whereas in 18.9 % of pregnancies with OPS, no therapy has been given at all. One woman in OAPS and four women in TAPS were treated with plasmapheresis and immunoadsorption. There was no significant association between adverse obstetric outcome and therapy. The most frequent pregnancy complications were RFL in the OAPS group (32.4 vs. 13.5 % in TAPS) and PE in the TAPS group (18.9 % in OAPS and TAPS, respectively). The data of our study showed that pregnancies with OAPS and TAPS have a similar rate of pregnancy complications. However, pregnancies with OAPS tend to have rather RFL. Although we were not able to reveal a significant association with adverse obstetric outcome, it seems that the current adequate therapy for APS in pregnancy, consisting of LDA and LMWH, might rather prevent the development of RFL. Additionally, it might be considered to divide the obstetric APS into obstetric APS with early pregnancy complications and obstetric APS with late pregnancy complications. The division into two groups of obstetric APS might facilitate the choice of additional therapy in these women.

Background Our previous studies reported on the obstetric, periodontal, and microbiologic outcomes of women participating in the Obstetrics and Periodontal Therapy (OPT) Study. This article describes the systemic antibody responses to selected periodontal bacteria in the same patients. Methods Serum samples, obtained from pregnant women at baseline (13 to 16 weeks; 6 days of gestation) and 29 to 32 weeks, were analyzed by enzyme-linked immunosorbent assay for serum immunoglobulin G (IgG) antibody to Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans), Campylobacter rectus, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia (previously T. forsythensis), and Treponema denticola. Results At baseline, women who delivered live preterm infants had significantly lower total serum levels of IgG antibody to the panel of periodontal pathogens (P = 0.0018), to P. gingivalis (P = 0.0013), and to F. nucleatum (P = 0.0200) than women who delivered at term. These differences were not significant at 29 to 32 weeks. Changes in IgG levels between baseline and 29 to 32 weeks were not associated with preterm birth when adjusted for treatment group, clinical center, race, or age. In addition, delivery of low birth weight infants was not associated with levels of antibody at baseline or with antibody changes during pregnancy. Conclusions Live preterm birth is associated with decreased levels of IgG antibody to periodontal pathogens in women with periodontitis when assessed during the second trimester. Changes in IgG antibody during pregnancy are not associated with birth outcomes. PMID:19485826

Gastric cancer remains a significant health problem worldwide and surgery is currently the only potentially curative treatment option. Gastric cancer surgery is generally considered to be high risk surgery and five-year survival rates are poor, therefore a continuous strive to improve outcomes for these patients is warranted. Fortunately, in the last decades several potential advances have been introduced that intervene at various stages of the treatment process. This review provides an overview of methods implemented in pre-, intra- and postoperative stage of gastric cancer surgery to improve outcome. Better preoperative risk assessment using comorbidity index (e.g., Charlson comorbidity index), assessment of nutritional status (e.g., short nutritional assessment questionnaire, nutritional risk screening - 2002) and frailty assessment (Groningen frailty indicator, Edmonton frail scale, Hopkins frailty) was introduced. Also preoperative optimization of patients using prehabilitation has future potential. Implementation of fast-track or enhanced recovery after surgery programs is showing promising results, although future studies have to determine what the exact optimal strategy is. Introduction of laparoscopic surgery has shown improvement of results as well as optimization of lymph node dissection. Hyperthermic intraperitoneal chemotherapy has not shown to be beneficial in peritoneal metastatic disease thus far. Advances in postoperative care include optimal timing of oral diet, which has been shown to reduce hospital stay. In general, hospital volume, i.e., centralization, and clinical audits might further improve the outcome in gastric cancer surgery. In conclusion, progress has been made in improving the surgical treatment of gastric cancer. However, gastric cancer treatment is high risk surgery and many areas for future research remain.

Background Obesity and gestational diabetes mellitus (GDM) increase the morbidity of the mother and newborn, which could increase further should they coexist. We aimed to determine the risk of adverse pregnancy and neonatal outcomes associated with excess weight (EW), and within this group identify potential differences between those with and without GDM. Methods We carried out a post-hoc analysis of the St. Carlos Gestational Study which included 3312 pregnant women, arranged in 3 groups: normal-weight women (NWw) (2398/72.4%), overweight women (OWw) (649/19.6%) and obese women (OBw) (265/8%). OWw and OBw were grouped as EW women (EWw). We analyzed variables related to adverse pregnancy and neonatal outcomes. Results The relative risk (95% CI) for GDM was 1.82 (1.47 to 2.25; p<0.0001) for OWw, and 3.26 (2.45 to 4.35; p<0.0001) in OBw. Univariate analysis showed associations of EW to higher rates of prematurity, birth weight >90th centile, newborns admitted to neonatal intensive care unit (NICU), instrumental delivery and cesarean delivery (all p<0.005). Multivariate analysis, adjusted for parity and ethnicity, showed that EW increased the risk of prematurity, admission to NICU, cesarean and instrumental delivery, especially in EWw without GDM. NWw with GDM had a significantly lower risk of admission to NICU and cesarean delivery, compared with NWw without GDM. Conclusions EW is detrimental for pregnancy and neonatal outcomes, and treatment of GDM contributes to lowering the risk in EWw and NWw. Applying the same lifestyle changes to all pregnant women, independent of their weight or GDM condition, could improve these outcomes. PMID:28074143

The objective of this study was to evaluate three commonly used methods for endometritis diagnosis by comparing each one's association with the presence of intrauterine Trueperella pyogenes (TP) and reproductive performance. Lactating Holstein cows (n = 452) were evaluated a single time at 35 ± 3 days postpartum to diagnose endometritis on the basis of three criteria: presence of purulent vaginal discharge (PVD) detected by a Metricheck device, presence of purulent uterine lavage fluid (PUL), presence of cytologic endometritis (CE) based on relative abundance of polymorphonuclear leukocytes in uterine lavage fluid. A threshold of polymorphonuclear leukocytes greater than 5% was used to diagnose the occurrence of CE. Also, a swab of the uterine lavage was cultured to evaluate the presence of TP and determine its association with endometritis diagnosis criteria and pregnancy outcomes. The results showed that cows positive for TP had increased prevalence of PVD and PUL and tended to have greater prevalence of CE. Median time to pregnancy was 56 days longer, and hazard of pregnancy was 34% lower for TP-positive cows than for TP-negative cows. Presence of PUL led to a 35% lower hazard of pregnancy and 34-day-longer median time to pregnancy than cows without PUL. Likewise, cows diagnosed with PVD had a 47% lower hazard of pregnancy and 57-day-longer median time to pregnancy than cows without PVD. Cows diagnosed with CE had a 27% lower hazard of pregnancy and 42-day-longer median time to pregnancy than cows without CE. When the three different diagnostic methods were used as independent variables in a Cox's proportional hazard model that evaluated hazard of pregnancy, the variable PVD was the only statistically significant variable. Combined PUL and CE or combined PUL and PVD had no additional effects on hazard of pregnancy when compared with only PUL, only PVD, or only CE as the criterion to determine endometritis. However, combined PVD and CE had an additive

Background: Pregnancy is associated with unfavorable metabolic profile, which might in turn result in adverse pregnancy outcomes. The current study was designed to evaluate the effects of calcium plus Vitamin D administration on metabolic status and pregnancy outcomes in healthy pregnant women. Methods: This randomized double-blind placebo-controlled clinical trial was performed among 42 pregnant women aged 18–40 years who were at week 25 of gestation. Subjects were randomly allocated to consume either 500 mg calcium-200 IU cholecalciferol supplements (n = 21) or placebo (n = 21) for 9 weeks. Blood samples were obtained at the onset of the study and after 9-week trial to determine related markers. Post-delivery, the newborn's weight, length, and head circumference were measured during the first 24 h after birth. Results: Consumption of calcium-Vitamin D co-supplements resulted in a significant reduction of serum high-sensitivity C-reactive protein levels compared with placebo (−1856.8 ± 2657.7 vs. 707.1 ± 3139.4 μg/mL, P = 0.006). We also found a significant elevation of plasma total antioxidant capacity (89.3 ± 118.0 vs. −9.4 ± 164.9 mmol/L, P = 0.03), serum 25-hydroxyvitamin D (2.5 ± 3.5 vs. −1.7 ± 1.7 ng/mL, P < 0.0001), and calcium levels (0.6 ± 0.6 vs. −0.1 ± 0.4 mg/dL, P < 0.0001). The supplementation led to a significant decrease in diastolic blood pressure (−1.9 ± 8.3 vs. 3.1 ± 5.2 mmHg, P = 0.02) compared with placebo. No significant effect of calcium-Vitamin D co-supplements was seen on other metabolic profiles. We saw no significant change of the co-supplementation on pregnancy outcomes as well. Conclusions: Although calcium-Vitamin D co-supplementation for 9 weeks in pregnant women resulted in improved metabolic profiles, it did not affect pregnancy outcomes. PMID:27076887

Genital mycoplasmas are frequently found in the vaginal flora across socioeconomic and ethnic groups and have been demonstrated to be involved in adverse perinatal outcomes. Both Mycoplasma and Ureaplasma spp cause inflammation potentially leading to spontaneous preterm birth and PPROM as well as postdelivery infectious complications and neonatal infections. Herein we have provided an overview of the existing literature and supportive evidence for genital mycoplasma's role in perinatal complications. Future research will need to focus on clearly delineating the species, allowing for discrimination of their effects.

In a new trial, provision of antenatal dietary and lifestyle advice to pregnant women who are obese is associated with modest improvements in maternal diet. This intervention is, however, inadequate to affect pregnancy and birth outcomes, and challenges the notion that limiting gestational weight gain can improve pregnancy outcomes.

Teenage pregnancies are still listed among the most important public health problems of the 21st century, although low maternal age may be a marker for social rather than biological or medical disadvantage. In the present study 51 pregnant Austrian girls ageing between 13 and 18 years (x = 16.3 yrs; +/- 1.3) who decided to give birth were enrolled. All girls were interviewed based on a structured questionnaire furthermore data from the mother-child pass port were included in the analysis. 28 girls gave birth shortly before the interview took place. Complications during pregnancy and birth were seldom and no adverse birth outcome was observed. The majority of participants received optimal medical treatment and sufficient social support from relatives and school but also from public and private institutions during pregancy. It can be concluded that social support and adequate medical treatment reduce the risk of teenage pregnancies markedly.

To study the supplementary effect of Spirulina, pregnant rats were fed 5 different kinds of diets (casein, Spirulina, wheat gluten, Spirulina + wheat gluten, Spirulina-without additional vitamins and minerals), each providing 22% protein during the period of pregnancy. The outcome of pregnancy was assessed from litter and dams' weight and litter size. Maternal weight gain was found to be maximum with Spirulina + wheat gluten and least with the wheat gluten diet. Rats receiving Spirulina containing diets produced significantly (p < 0.05) higher litter size than those receiving casein and wheat gluten. In spite of having higher litter size, Spirulina containing diet groups produced pups with birth weights comparable to those of casein. Spirulina appears to be a good dietary supplement during pregnancy.

Stress and adverse environmental surroundings result in suboptimal conditions in a pregnant mother such that she may experience poor pregnancy outcome including complete pregnancy failure and preterm labor. Furthermore her developing baby is at risk of adverse programming, which confers susceptibility to long term ill health. While some mechanisms at the feto-maternal interface underlying these conditions are understood, the underlying cause for their adverse adaptation is often not clear. Progesterone plays a key role at many levels, including control of neuroendocrine responses to stress, procuring the required immune balance and controlling placental and decidual function, and lack of progesterone can explain many of the unwanted consequences of stress. How stress that is perceived by the mother inhibits progesterone secretion and action is beginning to be investigated. This overview of maternal neuroendocrine responses to stress throughout pregnancy analyses how they interact to compromise progesterone secretion and precipitate undesirable effects in mother and offspring.

The growing complexity of biomedical research requires new methods of discovery; scientists must use an interdisciplinary approach and explore new models of team science, as underscored in the Roadmap of the National Institutes of Health. In March 2003, the National Institute of Nursing Research convened a working group of scientists and clinicians with a wide range of backgrounds to address "Optimizing Pregnancy Outcomes in Minority Populations." The 2-day meeting included a variety of presentations on the current state of research on pregnancy in minority populations. Many participants provided specific insights regarding biobehavioral issues in human-environment interaction, stress and health status relationships to risk, maternal-fetal interactions, and the complications of pregnancy. This supplement presents articles from several participants at this interdisciplinary meeting. The National Institute of Nursing Research looks forward to further collaborations across the National Institutes of Health and other agencies to achieve the vital aims of this working group.

The relation between irregular and inconvenient working hours and the outcome of pregnancy was studied among women employed at a hospital in Sweden some time between 1980 and 1984. A questionnaire was distributed to 807 women; 81% replied. The pregnancies were divided into six groups with respect to work schedules during pregnancy. A slightly, but not significantly, increased risk of miscarriage was found in women who worked irregular hours or rotating shifts compared with women who worked only during the day (RR = 1.44, 95% confidence interval 0.83-2.51). Infants of non-smoking mothers who worked irregular hours had significantly lower birth weights than infants of non-smoking women working day time only. This difference was largest at birth order 2+. Similar results were found for infants of this birth order whose non-smoking mothers worked evenings or rotating shift. PMID:2818973

Immunosuppressive drugs may influence spermatogenesis, but little is known about outcome of pregnancies fathered by transplanted males. We estimated risk of adverse outcomes in pregnancies (with data after the first trimester) fathered by males that had undergone organ transplantation and were treated with immunosuppression. A population-based study, linking data from the Norwegian transplant registry and the Medical Birth Registry of Norway during 1967-2009 was designed. All Norwegian men undergoing solid organ transplantation were included. Odds ratios for major malformations, preeclampsia, preterm delivery (<37 weeks) and small-for-gestational-age were obtained using logistic regression. A total of 2463 transplanted males, fathering babies of 4614 deliveries before and 474 deliveries after transplantation were identified. The risk of preeclampsia was increased (AOR: 7.4, 95% CI: 1.1-51.4,) after transplantation compared to prior to transplantation. No increased risk was found for congenital malformations or other outcomes when compared with pregnancies before transplantation or with the general population (2 511 506 births). Our results indicate an increased risk of preeclampsia mediated through the transplanted and immunosuppressed father. Importantly, no increased risk was found for other adverse obstetric outcomes or malformations, which may reassure male transplant recipients planning to father children.

In spite of the recognition of potentially toxic chemicals in chlorinated drinking water, few studies have evaluated reproductive health consequences of such exposure. Using data from a case-control study of miscarriage, preterm delivery, and low birth weight in central North Carolina, we evaluated risk associated with water source, amount, and trihalomethane (THM) concentration. Water source was not related to any of those pregnancy outcomes, but an increasing amount of ingested water was associated with decreased risks of all three outcomes (odds ratios around 1.5 for 0 glasses per day relative to 1-3 glasses per day, falling to 0.8 for 4+ glasses per day). THM concentration and dose (concentration x amount) were not related to pregnancy outcome, with the possible exception of an increased risk of miscarriage in the highest sextile of THM concentration (adjusted odds ratio = 2.8, 95% confidence interval = 1.1-2.7), which was not part of an overall dose-response gradient. These data do not indicate a strong association between chlorination by-products and adverse pregnancy outcome, but given the limited quality of our exposure assessment and the increased miscarriage risk in the highest exposure group, more refined evaluation is warranted.

Prior research has established associations between pregnancy outcomes and specific neighborhood characteristics, including economic disadvantage, violent crime, and racial/ethnic segregation. Recently, associations have also been found between various health outcomes and group density, the degree to which an individual is a racial or ethnic majority in his or her local community. The objective of this study was to determine the extent to which census tract economic disadvantage, violent crime rate, and group density are associated with pregnancy outcomes among White, Black, and Hispanic infants in a large metropolitan setting. This cross-sectional study utilized 1990 census data, 1991 crime data, and 1991 birth certificate information for singleton live births in Chicago, Illinois. Results show substantial racial segregation in Chicago, with 35% of census tracts having more than 90% Black residents and 45% of census tracts having fewer than 10% Black residents. After stratifying by maternal race/ethnicity, we used multilevel analyses to model pregnancy outcomes as a function of individual and census tract characteristics. Among all racial/ethnic groups, violent crime rate accounted for most of the negative association between tract economic disadvantage and birth weight. Group density was also associated with birth weight but this association was stronger among Whites and Hispanics than among Blacks. Further analysis revealed that group density was more strongly associated with preterm birth while violent crime rate was more strongly associated with small for gestational age. These results suggest that group density and violent crime may impact birth weight via different mechanisms.

Acute viral hepatitis is the most common cause of jaundice in pregnancy. Amongst hepatitis E bears a deadly combination with pregnancy, leading to loss of very young lives. There is almost no data available in this aspect documenting prevalence, profile and effect of jaundice on outcome of pregnancy in Bangladesh. This observational study was done to determine and analyze the frequency, cause and outcome of jaundice in pregnancy among the admitted patients in the feto-maternal medicine wing of Bangabandhu Sheikh Mujib Medical University, for a 2 years period from August 2009 to July 2011. Management was done in collaboration with the hepatologists, hematologists and intensive care unit specialist. Outcome was noted in terms of the mode of delivery, maternal complications, need of blood transfusion and fresh frozen plasma and maternal end result. Fetal outcome was assessed by birth weight, Apgar score, neonatal admission, and perinatal mortality. Prevalence of jaundice was found 2.5% among all high risk and 1.3% among all obstetric admissions. Hepatitis E was the commonest cause and responsible for 80.4% cases of jaundice and next was cholestatic jaundice. Almost half of the patients (43.4%) faced complications like post partum haemorrhage (15.3%), hepatic encephalopathy (10.8%), ante partum hemorrhage (6.5%). Preterm delivery was noted in 71.1% cases. Out of 46 patients with jaundice four (4) mothers died due to hepatic encephalopathy in hepatitis E group. Regarding perinatal outcome 55.8% were of low birth weight, 35.3% had low Apgar score and perinatal mortality was 6.4%.

Objective To investigate the association between weekly weight gain, during the second and third trimesters, classified according to the 2009 Institute of Medicine (IOM/NRC) recommendations, and maternal and fetal outcomes. Methods Gestational weight gain was evaluated in 2,244 pregnant women of the Brazilian Study of Gestational Diabetes (Estudo Brasileiro do Diabetes Gestacional – EBDG). Outcomes were cesarean delivery, preterm birth and small or large for gestational age birth (SGA, LGA). Associations between inadequate weight gain and outcomes were estimated using robust Poisson regression adjusting for pre-pregnancy body mass index, trimester-specific weight gain, age, height, skin color, parity, education, smoking, alcohol consumption, gestational diabetes and hypertensive disorders in pregnancy. Results In fully adjusted models, in the second trimester, insufficient weight gain was associated with SGA (relative risk [RR] 1.72, 95% confidence interval [CI] 1.26–2.33), and excessive weight gain with LGA (RR 1.64, 95% CI 1.16–2.31); in third trimester, excessive weight gain with preterm birth (RR 1.70, 95% CI 1.08–2.70) and cesarean delivery (RR 1.21, 95% CI 1.03–1.44). Women with less than recommended gestational weight gain in the 2nd trimester had a lesser risk of cesarean deliveries (RR 0.82, 95% CI 0.71–0.96) than women with adequate gestational weight gain in this trimester. Conclusion Though insufficient weight gain in the 3rd trimester was not associated with adverse outcomes, other deviations from recommended weight gain during second and third trimester were associated with adverse pregnancy outcomes. These findings support, in part, the 2009 IOM/NRC recommendations for nutritional monitoring during pregnancy. PMID:23382944

Purpose: To evaluate fertility after abdominal and/or pelvic irradiation in long-term female survivors. Methods and Materials: Puberty and pregnancy outcome were analyzed in female survivors of childhood cancer (aged <18 years) treated with abdominal and/or pelvic radiotherapy (RT) at one of two French centers (Nancy and Lyon) between 1975 and 2004. Data were obtained from medical records and questionnaires sent to the women. Results: A total of 84 patients who had received abdominal and/or pelvic RT during childhood and were alive and aged more than 18 years at the time of the study made up the study population. Of the 57 female survivors treated with abdominal RT that excluded the pelvis, 52 (91%) progressed normally through puberty and 23 (40%) had at least one recorded pregnancy. Of the 27 patients treated with pelvic RT, only 10 (37%) progressed normally through puberty and 5 (19%) had at least one recorded pregnancy. Twenty-two women (seventeen of whom were treated with pelvic RT) had certain subfertility. A total of 50 births occurred in 28 women, with one baby dying at birth; one miscarriage also occurred. There was a high prevalence of prematurity and low birth weight but not of congenital malformations. Conclusions: Fertility can be preserved in patients who undergo abdominal RT that excludes the pelvis, taking into account the other treatments (e.g., chemotherapy with alkylating agents) are taken into account. When RT includes the pelvis, fertility is frequently impaired and women can have difficulty conceiving. Nevertheless, pregnancies can occur in some of these women. The most important factor that endangers a successful pregnancy after RT is the total dose received by the ovaries and uterus. This radiation dose has to be systematically recorded to improve our ability to follow up patients.

Vascular access dysfunction is the most frequent cause of hospitalization for end-stage renal disease (ESRD) patients. Our system of vascular access care and industry standards developed for historic reasons have resulted in a haphazard approach to access management. The Dialysis Outcome Quality Initiative has provided a road map for improving vascular access management. However, despite widespread acceptance, these recommendations are not routinely followed. This is largely the result of inertia coupled with systemic barriers to improving access outcomes. These barriers include lack of funded pre-ESRD care and preoperative imaging, lack of reimbursement for access monitoring, unavailable surgical and interventional suites, erosion of the real value of the composite rate, bundling of additional new services without rate adjustment, poor accountability of surgeons and hospitals, and a reimbursement system that rewards procedures and, in particular, graft and catheter placement. Currently, Center for Medicare and Medicaid Services is reevaluating the composite rate and its included bundle of services. To provide the best access care with the fewest complications while insuring multidisciplinary involvement and accountability, a realistic appraisal and realignment of incentives must be developed to insure improvement of access care in the United States.

Objective To investigate equity of patient outcomes in a psychological therapy service, following increased access achieved by a quality improvement (QI) initiative. Design Retrospective service evaluation of health outcomes; data analysed by ANOVA, chi-squared and Statistical Process Control. Setting A psychological therapy service in Westminster, London, UK. Participants People living in the Borough of Westminster, London, attending the service (from either healthcare professional or self-referral) between February 2009 and May 2012. Intervention(s) Social marketing interventions were used to increase referrals, including the promotion of the service through local media and through existing social networks. Main Outcome Measure(s) (i) Severity of depression on entry using Patient Health Questionnaire-9 (PHQ9). (ii) Changes to severity of depression following treatment (ΔPHQ9). (iii) Changes in attainment of a meaningful improvement in condition assessed by a key performance indicator. Results Patients from areas of high deprivation entered the service with more severe depression (M = 15.47, SD = 6.75), compared with patients from areas of low (M = 13.20, SD = 6.75) and medium (M = 14.44, SD = 6.64) deprivation. Patients in low, medium and high deprivation areas attained similar changes in depression score (ΔPHQ9: M = −6.60, SD = 6.41). Similar proportions of patients achieved the key performance indicator across initiative phase and deprivation categories. Conclusions QI methods improved access to mental health services; this paper finds no evidence for differences in clinical outcomes in patients, regardless of level of deprivation, interpreted as no evidence of inequity in the service with respect to this outcome.

Most patients with single ventricle (SV) congenital heart disease are expected to survive to adulthood. Women with SV are often counseled against pregnancy; however, data on pregnancies in these women are lacking. We sought to evaluate in-hospital outcomes of pregnancy in women with SV. We used nationally representative data from the 1998 to 2012 National Inpatient Sample to identify women ≥18 years of age admitted to the hospital with International Classification of Diseases-9th Revision codes for an intrauterine pregnancy and a diagnosis of hypoplastic left heart syndrome, tricuspid atresia, or common ventricle. A matched comparison group without a diagnosis of congenital heart disease or pulmonary hypertension was identified from the database. National estimates of hospitalizations were calculated. Length of stay, hospital charges, and complications were analyzed and compared between groups. Charge data were adjusted to 2012 dollars. There were 282 admissions of pregnant women with SV (69% with deliveries) and 1,405 admissions in the control group (88% with deliveries). Vaginal delivery was more common in SV (74% vs 71%, p <0.001). Length of stay (4.1 ± 0.91 vs 2.8 ± 0.18 days, p <0.001) and charges ($30,787 ± 8,109 vs $15,536 ± 1,006, p <0.0001) were higher in the SV group. Complications occurred in most SV admissions and were more common in the SV group than in the control group. No deaths occurred. Cardiovascular complications occurred in 25% of pregnancy-related hospitalizations, although in-hospital pregnancy-related death is rare. Vaginal delivery is common in these patients. These data suggest that pregnancy and vaginal delivery can be tolerated in women with SV, although the risk for a cardiovascular event is significantly higher than in the general population.

Chinese medicine is a common name for a collection of Chinese Materia Medica with therapeutic properties for medical treatment and healing. Similar to Western pharmaceuticals, Chinese medicines are not free of risk, and have the potential to cause adverse pregnancy outcomes and affect embryonic and fetal development. However, most clinical data concerning safety of maternal exposure to Chinese medicines during pregnancy are not available and the conclusion remains elusive. Some individual clinical trials of Chinese medicines reported some minor adverse effects during pregnancy, whereas few animal studies identified some adverse maternal and perinatal effects, as well as embryotoxic potentials. Basic research and mechanistic studies of the teratogenicity of Chinese medicines are still lacking. There is an urgent need for testing the safety of Chinese medicines before recommendation and commercialization. Until more reliable and scientific research data become available, clinicians should consider both the risks and benefits before recommending Chinese medicines to pregnant women. More systematic investigations of the safety implications of the use of Chinese medicines are highly recommended, in addition to more clinical trials with a larger sample size to confirm its safety during pregnancy. This review includes a critical overview of available clinical and experimental data and provides directions to study the safety issue of Chinese medicines for pregnancy.

Investigations in the rat model of pregnancy indicate an important role for the corpus luteal (CL) hormone relaxin in the maternal circulatory and osmoregulatory changes in pregnancy, which are epitomized by profound vasodilation and modest hypoosmolality, respectively. In a pilot study of infertile women who became pregnant through donor eggs, in vitro fertilization, and embryo transfer, the gestational rise in glomerular filtration and fall in plasma osmolality were markedly subdued. Because these women were infertile, they lacked a CL and circulating relaxin (and possibly other vasoactive CL hormones). Based on these findings in pregnant rats and women, we hypothesize that infertile women conceiving through donor eggs will have overall subdued circulatory changes (e.g., attenuated reduction in systemic vascular resistance and subdued increase in cardiac output) particularly during early pregnancy when CL hormones predominate before the full development and maturation of the placenta. In contrast, infertile women conceiving by autologous eggs retrieved after ovarian stimulation and fresh embryo transfer may have a relatively hyperdynamic circulation due to the presence of many CL (up to 20 or more) and higher circulating levels of vasodilatory ovarian hormones such as relaxin. Emerging evidence suggests that women undergoing Assisted Reproductive Technologies (ART) have increased risk for adverse pregnancy outcomes such as preeclampsia and small for gestational-age babies. This increased risk may be partly caused by the maternal milieu, which is not physiological in ART pregnancies due to the abnormal status of the CL.

Women may be infected during pregnancy with infectious agents that are often passed unnoticed; however, the causative agent may still traverse the placenta and infect the developing embryo and fetus. Several of these agents (i.e. rubella, cytomegalovirus or Toxoplasma Gondii) may cause severe fetal damage, but most other infections in pregnancy seem to be much less dangerous to the fetus. In this review we discuss the effects of several viral infections during pregnancy where the effects on the developing embryo and fetus are infrequent, but they may sometimes cause severe neonatal disease. The following viruses are discussed: coxsackie and echoviruses, measles and mumps, polioviruses, Japanese and Venezuelan equine encephalitis viruses, West Nile virus and hepatitis viruses A, B, C, D and E. Coxsackie B virus may cause an increase in early spontaneous abortions and rarely, fetal myocarditis; echoviruses do not seem to damage the fetus; measles and mumps may cause increased early and late fetal death and neonatal measles or mumps. The viruses affecting the nervous system may increase early and late spontaneous abortions and, rarely, cause severe damage to the fetal brain. Hepatitis B virus has a high rate of vertical transmission causing fetal and neonatal hepatitis. Hepatitis A, C and E are rarely transmitted trans-placentally; if transmitted, they may cause hepatitis. There is no evidence that immunization in pregnancy against these diseases (with attenuated viruses) may adversely affect pregnancy outcome.

Introduction Adolescent childbearing has been viewed as a social, political, and public health priority since the 1970s. Research has primarily focused on the negative consequences of teen pregnancy; less research has explored factors associated with healthy pregnancy and birth experiences in this population. Methods Using open-ended and qualitative techniques, researchers performed individual interviews with fifteen adolescent mothers (15–19 years of age) recruited from a Women’s and Children’s Clinic in Southern Louisiana, who had experienced a healthy pregnancy and bore a full-term, normal birth weight infant. We used a resiliency framework to identify factors that may have supported positive health outcomes despite risks associated with low-income and/or marginalized minority status. Results A total of 15 mothers of multiple racial/ethnic identities were included in the analysis. Mothers discussed potential protective factors that we classified as either assets (internal factors) or resources (external factors). Mothers demonstrated strong assets including self-efficacy and self-acceptance and important resources including familial support and partner support during pregnancy which may have contributed to their resiliency. Discussion Ensuring access to social and structural supports as well as supporting adolescent-friendly health and social policies may be key to promoting healthy maternal and infant outcomes among young women who become pregnant.

A substantial proportion of the etiology involved in female infertility and adverse pregnancy outcomes remains idiopathic. Recent scientific research has suggested a role for environmental factors in these conditions. Secondhand tobacco smoke (STS) contains a number of known or suspected reproductive toxins, and human exposure to STS is prevalent worldwide. Robust evidence exists for the toxic effects of active smoking on fertility and pregnancy, but studies of passive exposure are much more limited in number. While the association between maternal STS exposure and declined birth weight has been fairly well-documented, only recently have epidemiologic studies begun to provide suggestive evidence for delayed conception, altered menstrual cycling, early pregnancy loss (e.g. spontaneous abortion), preterm delivery, and congenital malformations in relation to STS exposure. There is also new evidence that developmental exposures to tobacco smoke may be associated with reproductive effects in adulthood. To date, most studies have estimated maternal STS exposure through self-report even though exposure biomarkers are less prone to error and recall bias. In addition to utilizing biomarkers of STS exposure, future studies should aim to identify vital windows of STS exposure, important environmental co-exposures, individual susceptibility factors, and specific STS constituents associated with female infertility and adverse pregnancy outcomes. The role of paternal exposures/factors should also be investigated. PMID:23888128

This study investigates the effects of anticoagulant therapy on pregnancy outcomes in 204 patients with thrombophilia and previous poor obstetric outcomes. Patients with poor obstetric history (pre-eclampsia, intrauterine growth retardation, fetal death, placental abruption, recurrent pregnancy loss) and having hereditary thrombophilia were included in this study. Poor obstetric outcomes were observed more frequently in patients who had not taken anticogulant therapy compared with treated group. Live birth rate, gestational age at birth and Apgar scores were significantly higher in the treated group when compared with the untreated group. There were no significant differences in terms of birthweight, mode of delivery and admission rates to the neonatal intensive care unit (NICU). Low-molecular-weight heparin (LMWH) plus acetylsalicylic acid (ASA) had higher gestational age at birth, Apgar scores, live birth rate and a lower abortion rates when compared with controls; in contrast, no significant difference was observed in terms of birthweight, mode of delivery, obstetric complications and admission rates to NICU. There were no significant differences between control group and both LMWH only and ASA only groups in terms of gestational age at birth, Apgar scores, birthweight, mode of delivery, obstetric complications and admission rates to NICU. Only LMWH group had higher live birth rate as compared with control group. The use of only ASA did not seem to affect the perinatal complication rates and outcomes. In conclusion, anticoagulant therapy with both LMWH and ASA seems to provide better obstetric outcomes in pregnant women with thrombophilia and previous poor obstetric outcomes.

Studies conducted over the past 25 years have focused on the role of periodontitis, an inflammatory condition of microbial etiology that destroys the tooth supporting tissues, as a systemic inflammatory stressor that can act as an independent risk factor of atherosclerotic vascular disease (AVSD) and adverse pregnancy outcomes (APOs). It has been suggested that periodontitis-associated bacteremias and systemic dissemination of inflammatory mediators produced in the periodontal tissues may result in systemic inflammation and endothelial dysfunction, while bacteria of oral origin may translocate into the feto-placental unit. Epidemiologic studies largely support an association between periodontitis and ASVD / APOs independent of known confounders; indeed, periodontitis has been shown to confer statistically significantly elevated risk for clinical events associated with ASVD and APOs in multivariable adjustments. On the other hand, intervention studies demonstrate that although periodontal therapy reduces systemic inflammation and improves endothelial function, it has no positive effect on the incidence of APOs. Studies of the effects of periodontal interventions on ASVD-related clinical events are lacking. This review summarizes key findings from mechanistic, association and intervention studies and attempts to reconcile the seemingly contradictory evidence that originates from different lines of investigation.

From 1.3.73 to 30.9.80 5580 women had an amniocentesis performed here or elsewhere; fetal chromosome analyses were carried out in this laboratory. We found 112 abnormal karyotypes (2 per cent) out of 5591 chromosome analyses. In 40 women (0.7 per cent) no cytogenetic diagnosis was obtained. Follow-up was successful in 99.5 per cent. Nine cases are reported in detail: Three cases had discrepancy between the karyotype in amniotic fluid and peripheral blood after delivery, two of these cases turned out to be 46,XX (male) while the third was prenatally determined as trisomy 21, but had a 46,XX karyotype at birth. Six cases had discrepancy between the karyotype in amniotic fluid and the phenotypic outcome at birth/abortion. One case was a prenatally undetected 45,X/46,XY mosaicism; one case was an unexplained 45,X male fetus; two cases were prenatally determined as trisomy 21, but at abortion a normal karyotype was determined and in two cases maternal cells were probably examined. The incidence of cytogenetic errors in this study was very low.

Given the negative developmental risks associated with adolescent motherhood, it is important to examine the sociocultural context of adolescent mothers' lives to identify those most at risk for poor outcomes. Our goals were to identify profiles of Mexican-origin pregnant adolescents' cultural orientations and their attitudes toward teen pregnancy, and to investigate how these profiles were linked to adolescents' pregnancy intentions, family resources, and short-term family, educational, and parenting outcomes. With a sample of 205 Mexican-origin adolescent mothers, we identified three profiles based on cultural orientations and attitudes toward teen pregnancy: Bicultural-Moderate Attitudes, Acculturated-Moderate Attitudes, and Enculturated-Low Attitudes. The results indicated that enculturated pregnant adolescents had the least favorable attitudes toward teen pregnancy, and the lowest levels of family income, pregnancy intentions, pregnancy support, and educational expectations compared to acculturated and bicultural pregnant adolescents; acculturated adolescents (with the highest family income and high levels of pregnancy support) had the highest levels of parenting efficacy 10 months postpartum. Our findings suggest that enculturated adolescent mothers (with less positive attitudes toward teen pregnancy) may benefit from educational support programs and enculturated and bicultural adolescent mothers (with moderately positive attitudes toward teen pregnancy) may benefit from programs to increase parenting efficacy. Such targeted interventions may, in turn, reduce the likelihood of adolescent mothers experiencing negative educational and parenting outcomes.

Background Obesity and gestational diabetes (GDM) in pregnancy are recognized risk factors for adverse outcomes, including cesarean section (CS), macrosomia and preeclampsia. The aim of this study was to investigate the independent effect of GDM and obesity on the adverse pregnancy outcomes at term. Methods A retrospective cohort of postpartum women, in King Khalid University Hospital, were stratified according to body mass index (obese ≥30 kg/m2, non-obese <30 kg/m2) and the results of GDM screening into the following groups, women with no obesity and no GDM (reference group), women with no obesity but with GDM, women with obesity but no GDM and women with both GDM and obesity. Adverse pregnancy outcomes included high birth weight, macrosomia, CS delivery and preeclampsia. Multiple logistic regression used to examine independent associations of GDM and obesity with macrosomia and CS. Results 2701 women were included, 44% of them were obese and 15% had GDM. 63% of the women with GDM were obese. There was significant increase in the percentage of macrosomia, P < 0.001, high birth weight, P < 0.001, CS, P < 0.001 and preeclampsia, P < 0.001 in women with GDM and obesity compared to the reference group. Obesity increased the estimated risk of CS delivery, odds ratio (OR) 2.16, confidence intervals (CI) 1.74-2.67. The combination of GDM and obesity increased the risk of macrosomia OR 3.45, CI 2.05-5.81 and the risk of CS delivery OR 2.26, CI 1.65-3.11. Conclusion Maternal obesity and GDM were independently associated with adverse pregnancy outcomes. The combination of both conditions further increase the risk. PMID:24923207

This article summarizes our experience using administrative, survey, and telephone information to define asthma severity, impairment, risk, and quality of care in our large Kaiser Permanente population. Our data suggest that the 2-year Healthcare Effectiveness Data and Information Set definition of persistent asthma is a good surrogate for survey-defined persistent asthma, and thus it would be reasonable to direct asthma population management and quality-of-care assessments at patients with Healthcare Effectiveness Data and Information Set-defined persistent asthma for 2 years in a row. For population management, the numbers of short-acting β-agonist (SABA) canisters dispensed and validated tools on mail or telephone surveys have been used to assess asthma impairment. Algorithms based on pharmacy data (SABA canister and oral corticosteroid dispensings and prior emergency hospital care) have been used to assess the risk domain of asthma control. The asthma medication ratio (controllers divided by controllers plus SABAs) has been shown to be related to improved outcomes and is recommended as an asthma quality-of-care marker. It is hoped that outreach to patients and providers based on these indicators will improve asthma outcomes in patients cared for in individual practices, as well as in large health plans.

In 2005, a WHO consultation meeting on pregnancy intervals recommended a minimum interval of 6 months after a pregnancy disruption and an interval of two years after a live birth before attempting another pregnancy. Since then, studies have found contradictory evidence on the effect of shorter intervals after a pregnancy disruption. A binary regression analysis on 21532 last pregnancy outcomes from the 2000, 2005, and 2010 Rwanda Demographic and Health Surveys was done to assess the combined effects of the preceding pregnancy outcome and the interpregnancy intervals (IPIs) on fetal mortality in Rwanda. Risks of pregnancy loss are higher for primigravida and for mothers who lost the previous pregnancy and conceived again within 24 months. After a live birth, interpregnancy intervals less than two years do not increase the risk of a pregnancy loss. This study also confirms higher risks of fetal death when IPIs are beyond 5 years. An IPI of longer than 12 months after a fetal death is recommended in Rwanda. Particular attention needs to be directed to postpregnancy abortion care and family planning programs geared to spacing pregnancies should also include spacing after a fetal death. PMID:26613103

Background Since 1993, many studies on the health of Persian Gulf War veterans (PGWVs) have been undertaken. Some authors have concluded that an association exists between Gulf War service and reported infertility or miscarriage, but that effects on PGWV's children were limited. The present study's objective was to describe the reproductive outcome and health of offspring of French Gulf War veterans. Methods The French Study on the Persian Gulf War (PGW) and its Health Consequences is an exhaustive cross-sectional study on all French PGWVs conducted from 2002 to 2004. Data were collected by postal self-administered questionnaire. A case-control study nested in this cohort was conducted to evaluate the link between PGW-related exposures and fathering a child with a birth defect. Results In the present study, 9% of the 5,666 Gulf veterans who participated reported fertility disorders, and 12% of male veterans reported at least one miscarriage among their partners after the PGW. Overall, 4.2% of fathers reported at least one child with a birth defect conceived after the mission. No PGW-related exposure was associated with any birth defect in children fathered after the PGW mission. Concerning the reported health of children born after the PGW, 1.0% of children presented a pre-term delivery and 2.7% a birth defect. The main birth defects reported were musculoskeletal malformations (0.5%) and urinary system malformations (0.3%). Birth defect incidence in PGWV children conceived after the mission was similar to birth defect incidence described by the Paris Registry of Congenital Malformations, except for Down syndrome (PGWV children incidence was lower than Registry incidence). Conclusion This study did not highlight a high frequency of fertility disorders or miscarriage among French PGW veterans. We found no evidence for a link between paternal exposure during the Gulf War and increased risk of birth defects among French PGWV children. PMID:18442369

Escitalopram is a serotonin reuptake inhibitor prescribed for depression and anxiety. There is a paucity of information regarding safety in pregnancy. The objective of this study was to determine whether escitalopram is associated with an increased risk for major malformations or other adverse outcomes following use in pregnancy. The authors analyzed pregnancy outcomes in women exposed to escitalopram (n = 212) versus other antidepressants (n = 212) versus nonteratogenic exposures (n = 212) and compared the outcomes. Among the escitalopram exposures were 172 (81%) live births, 32 (15%) spontaneous abortions, 6 (2.8%) therapeutic abortions, 3 stillbirths (1.7%), and 3 major malformations (1.7%). The only significant differences among groups was the rate of low birth weight (<2500 g) and overall mean birth weight (P = .225). However, spontaneous abortion rates were higher in both antidepressant groups (15% and 16%) compared with controls (8.5%; P = .066). There were lower rates of live births (P = .006), lower overall birth weight (P < .001), and increased rates of low birth weight (<2500 g; P = .009) with escitalopram. Spontaneous abortion rates were nearly double in both antidepressant groups (15% and 16%) compared with controls (8.5%) but not significant (P = .066). Escitalopram does not appear to be associated with an increased risk for major malformations but appears to increase the risk for low birth weight, which was correlated with the increase in infants weighing <2500 g. In addition, the higher rates of spontaneous abortions in both antidepressant groups confirmed previous findings.

When pregnant adolescent sheep are overnourished to promote maternal growth during pregnancy, growth of the placenta is impaired and results in the premature delivery of low birth weight lambs relative to control-fed adolescents of equivalent age. These effects have been achieved by feeding two levels of the same complete diet. The present study evaluated the role of protein in pregnancy outcome in our adolescent sheep paradigm. Adolescent ewes were implanted with single embryos on day 4 post-oestrus. Thereafter ewes were offered ad libitum an isoenergetic diet (11.4 MJ metabolisable energy/kg DM) containing either 12% (basic, B) or 17% (extra, E) crude protein. At day 75 of gestation, half the pregnant ewes on each protein level were switched to yield four groups, BB, EE, BE and EB protein. A further optimally nourished control group received a moderate quantity of a ration (14% crude protein) designed to provide 100% of the estimated energy and protein requirement of the adolescent sheep according to stage of pregnancy. Pregnancy outcome was determined at term. Feed intakes were independent of protein level in the four groups of ewes fed ad libitum and were higher (P<0.001) than in the control group throughout. Maternal plasma urea concentrations reflected the current crude protein content of the diet offered and were elevated in the 17% compared with 12% protein groups (P<0.001). Within groups fed ad libitum, maternal plasma insulin, glucose, NEFA and homocysteine concentrations were largely independent of protein level. Gestation length, placental weight, lamb birth weight and initial colostrum yield were reduced (P<0.05) in all groups fed ad libitum relative to the optimally nourished control group. Similarly, total colostrum IgG, butterfat, lactose and crude protein content at parturition were attenuated in the ad libitum compared with the control groups. However, within ad libitum groups pregnancy outcome parameters were largely unaffected by level or timing

It has been reported that, compared with simple increased nuchal translucency, fetal cases with septated cystic hygroma (CH) are more likely to face perinatal handicaps. However, pediatric outcomes and proper prenatal counseling for this anomaly have not yet been truly defined. We performed this study to determine pregnancy and pediatric outcomes of fetuses with septated CH. We searched records for cases with septated CH and collected data for structural abnormalities, karyotype analysis, and pregnancy outcomes. Fetuses born with septated CH were also evaluated for their pediatric outcomes. Sixty-nine fetuses with septated CH were enrolled in the study. Results showed that chromosomal abnormalities were present in 28 fetuses (40.6%), and the most common aneuploidy was Turner syndrome (n=14, 20.3%); 16 (23.2%) of the remaining cases, in which aneuploidy was not found, had coexistent structural malformations; 25 (36.2%) cases had normal karyotype and morphology. The total number of live births and infants with unfavorable neurologic follow-up were 13 (18.8%) and 2 (2.9%), respectively. Septated CH is associated with poor perinatal outcomes; therefore, karyotype analysis and ultrasonographic anomaly screening should be performed as initial steps, and expectant management should be offered to couples with euploid fetuses that have normal morphology.

Background Iron deficiency anemia (IDA) is relatively common in the third trimester of pregnancy, but causal associations with low birth weight and compromised neonatal iron status are difficult to establish in human populations. Objective The objective was to determine the effects of diet-induced IDA on intrauterine growth and neonatal iron status in an appropriate animal model for third-trimester IDA in women. Design Hematologic and iron-status measures, pregnancy outcomes, and fetal and neonatal evaluations were compared between pregnant rhesus monkeys (n = 14) fed a diet containing 10 μg Fe/g diet from the time of pregnancy detection (gestation days 28–30) and controls (n = 24) fed 100 μg Fe/g diet. Results By the third trimester, 79% of the iron-deprived dams and 29% of the control monkeys had a hemoglobin concentration <11 g/dL. There were also significant group differences in hematocrit, mean corpuscular volume, transferrin saturation, serum ferritin, and serum iron. At birth, the newborns of monkeys iron-deprived during pregnancy had significantly lower hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin values and a lower ratio of erythroid to total colony-forming units in bone marrow than did the control newborns. Pregnancy weight gain did not differ significantly between the iron-deprived and control dams, and the fetuses and newborns of the iron-deprived dams were not growth retarded relative to the controls. Gestation length, the number of stillbirths, and neonatal neurobehavioral test scores did not differ significantly by diet group. Conclusion These data indicate that an inadequate intake of iron from the diet during pregnancy in rhesus monkeys can lead to compromised hematologic status of the neonate without indications of growth retardation or impaired neurologic function at birth.

Background: Despite significant efforts to understand adverse pregnancy outcome in women receiving Antiretroviral Therapy (ART), ART-related adverse birth outcomes are still poorly understood. We systematically review ART-related adverse birth outcomes among HIV-infected pregnant women; we also review the covariates associated with adverse birth outcomes in the aforementioned group. Methods: The main source for our systematic review was electronic bibliographic databases. Databases such as MEDLINE, PubMed, EMBASE and AIDSLINE were searched. Furthermore, search engines such as Google and Google Scholar were specifically searched for gray literature. Methodological quality of available literature was assessed using the Newcastle - Ottawa Quality Assessment Scale & M. Hewitt guideline. We examined a total of 1,124 papers and reviewed the studies using the PICOT criteria which stands for Patient (population), Intervention (or “Exposure”), Comparison, Outcome and Type of study. Finally, 32 methodologically fit studies were retained and included in our review. Results: Frequently observed adverse birth outcomes included low birth weight (LBW), Preterm Birth (PB), Small for Gestational Age (SGA), while still birth and congenital anomalies were infrequent. Type of regimen such as Protease Inhibitor (PI) based regimens and timing of initiation of ART are some of the factors associated with adverse pregnancy outcomes. Covariates principally included malnutrition and other co-morbidities such as malaria and HIV. Conclusions and Public Health Implications: There is growing evidence in published literature suggesting that ART might be causing adverse birth outcomes among pregnant women in developing countries. There is a need to consider regimen types for HIV-infected pregnant women. There is need to design large cohort studies. PMID:27621984

Introduction Tuberculosis (TB) remains the leading cause of death from a curable infectious disease; drug-resistant TB threatens to dismantle all prior gains in global control. Suboptimal circulating anti-TB drug concentrations can lead to lack of cure and acquired drug resistance. Areas covered This review will introduce pharmacokinetic parameters for key anti-TB drugs, as well as the indications and limitations of measuring these parameters in clinical practice. Current and novel methodologies for delivering anti-TB pharmacokinetic-pharmacodynamic data are highlighted and gaps in operational research described. Expert opinion Individual pharmacokinetic variability is commonplace, underappreciated and difficult to predict without therapeutic drug monitoring (TDM). Pharmacokinetic thresholds associated with poor TB treatment outcome in drug-susceptible TB have recently been described and may now guide the application of TDM, but require validation in a variety of settings and comorbidities. Dried blood spots for TDM and prepackaged multidrug plates for minimum inhibitory concentration testing will overcome barriers of accessibility and represent areas for innovation. Operationalizing pharmacokinetics has the potential to improve TB outcomes in the most difficult-to-treat forms of the disease such as multidrug resistance. Clinical studies in these areas are eagerly anticipated and we expect will better define the rational introduction of novel therapeutics. PMID:24597717

Introduction Thyroid autoimmunity can have an adverse impact on the outcome of the pregnancy. Although the adverse effects of antithyroid antibodies have been well studied in hypothyroid women, their effects in euthyroid women are not well evaluated. Aim The study was conducted to assess the overall prevalence of anti-Thyroid Peroxidase (anti-TPO) antibodies in pregnant women and the effect of anti-TPO positivity on the outcome of pregnancy in euthyroid women. Materials and Methods One thousand Indian women, in their first trimester were screened for anti-TPO antibodies to know the prevalence. Of this, euthyroid women who were positive for the presence of anti-TPO antibody were selected and their obstetric history was recorded. These women were followed up and the incidences of maternal and foetal complications were recorded. The complications were compared with the past obstetric history and outcomes in parity and gestation matched controls (anti-TPO negative). Results The prevalence of anti-TPO positivity was 11% (n=110). Out of the positives, those with elevated Thyroid Stimulating Hormone (TSH) were 6.5%. The prevalence of euthyroid women who were anti-TPO positive was 4% (n=40). Anti-TPO positive, euthyroid females had a higher prevalence of infertility, anaemia and preterm delivery as compared to the controls (p<0.0001). No differences were observed between the two groups in terms of history of abruption recurrent abortions, intrauterine growth restriction, postpartum haemorrhage, symptomatic hypothyroidism, hypertensive disorders of pregnancy and foetal complications. Conclusion Anti-TPO positivity is common in pregnant women. Anti-TPO positive euthyroid females had a higher prevalence of infertility, anaemia as well as preterm delivery. Our results indicate that anti-TPO screening in pregnancy, may aid in early identification of the women at risk. PMID:27790523

Background: Singleton pregnancy with a live birth beyond 37 weeks of gestation is the ultimate goal of any assisted reproductive technology. However, singletons conceived after ART are found to have a poor perinatal outcome in comparison to naturally conceived singletons. It was hypothesized that the outcome of singleton conceived after transfer of two or more embryos may be dependent on the sharing of uterine space with other embryos. Methods: Patients who had single gestational sac visualized at 6 weeks after transfer of 4, 3 or 2 embryos were considered for the study. 195 singleton pregnancies were selected for final evaluation such that as per implantation rates of 25%, 33%, and 50%, they were divided into 3 groups of 50, 82 and 63 cases, respectively. The basic characteristics of pregnancy (gestational age, birth weight) were compared using analysis of variance (continuous variables), and categorical variables were evaluated with chi-squared test. The p<0.05 was considered statistically significant. Results: Among the various variables including maternal age, conception, type of infertility, type of abortion, total live birth, gestational age in live birth, birth weight, kind of embryo transfer and gestational age, there was not significant statistical differences between groups except gestational age that it was higher in group with 50% (p<0.04) implantation rate. Therefore, higher number of initial embryos may affect the perinatal outcome of singleton conceived subsequently. Conclusion: There is higher chance of missed abortion in patients with singleton pregnancies conceived after multiple embryo transfer. Gestational age at delivery and birth weight were correlated with number of embryo transfered. PMID:28377897

This retrospective, cohort study examined the association between maternal pre-pregnancy body mass index (BMI), independent of glucose tolerance and adverse pregnancy outcomes in women with polycystic ovary syndrome (PCOS), for which there are few previous studies. Medical records from 2012 to 2015 at Guangzhou Women and Children's Medical Center, China were reviewed for women previously diagnosed with PCOS with normal 2-h 75-g oral glucose tolerance test (OGTT) results (n = 1249). The separate and joint effects of maternal BMI and glucose levels on pregnancy outcomes were assessed. Maternal pre-pregnancy BMI was associated with hypertensive disorders of pregnancy (HDP) (OR: 1.22, 95% CI: 1.02-1.45), preterm birth (OR: 1.49, 95% CI: 1.08-2.17), and large for gestational age (LGA) (OR: 1.69, 95% CI: 1.16-2.20). Elevated fasting glucose and maternal pre-pregnancy BMI were jointly associated with increased risks of HDP, preterm birth, and LGA. Therefore, among women with PCOS and normal glucose tolerance, maternal pre-pregnancy BMI is an independent risk factor of adverse pregnancy outcomes.

Objective To examine whether surgical procedures involving the uterine cervix were associated with pregnancy outcomes, including preterm birth, low birth weight, cesarean delivery and pregnancy loss. Design Population-based observational study nested in retrospective matched cohort Setting Kaiser Permanente Northwest integrated health plan in Oregon/Washington, U.S.A. Population Female health plan members age 14–53 years with documented pregnancies from 1998–2009. Women with prior excisional and ablative cervical surgical procedures (N = 322) were compared to women unexposed to cervical procedures (N = 4,307) and, separately, to those having undergone only diagnostic/biopsy procedures (N = 847). Methods Using log-linear regression models, we examined risk of adverse pregnancy outcomes in relation to prior excisional or ablative cervical surgical procedures. We stratified excisional procedures by excision thickness. We evaluated for confounding by age, body mass index, race, smoking history, previous preterm birth, and parity. Results We found a positive association between excisional treatment > = 1.0 cm and the outcomes preterm birth and low birth weight (preterm birth unadjusted risk ratio [RR] = 2.15, 95% confidence interval [CI] 1.16–3.98 for excisions ≥1.0 cm compared to unexposed women), particularly in women who delivered within one year of surgery (RR = 3.26, 95% CI 1.41–7.53). There was no clear association between excisional treatment and cesarean delivery, and treated women did not have a substantially higher risk of dysfunctional labor. Ablative treatment was not associated with low birth weight, preterm birth, or cesarean delivery but was associated with pregnancy loss (RR = 1.43, 95% CI 1.05–1.93 vs. unexposed women). Analyses using the diagnostic procedures comparison group produced similar results. Conclusion Women with > = 1.0 cm excisional treatment had elevated risk of preterm birth and low birth weight when compared to unexposed

Background: Trace elements and specially minerals are critical for the development of fetus. Many minerals are transferred to the fetus for fetal stores in the latter part of the pregnancy. It has been shown that various trace elements such as Zinc, Iron, Calcium and Magnesium are metabolically interrelated and there is alteration in their concentration during pregnancy. Beyond pregnancy is associated with increased demand of all the nutrients and deficiency of any of these could affect pregnancy, delivery and outcome of pregnancy. Aim: To study the levels of trace elements namely zinc, iron, magnesium and calcium in maternal and umbilical cord blood and their association with pregnancy outcome. Methods: Sixty pregnant women in Zabol, Iran were selected from those who had registered their names for the prenatal care and who had followed up till the 3rd trimester of pregnancy ending in child birth. Biochemical parameters analyzed with help of the biochemical laboratory. Data were analyzed by SPSS software. Results: The mean biochemical profile such, serum calcium, magnesium, zinc and iron in the pregnant women were as follow: in the 1st trimester 8.3, 1.9, 74.9 and 74.4 µg/dl respectively; in the 2nd trimester 8.5, 1.9, 73.1 and 79.3 µg/dl, respectively; in the 3rd trimester 8.6, 1.9, 68.4, and 82.2 µg/dl, respectively. In the umbilical cord blood, the mean serum calcium, magnesium, zinc and iron were 8.5, 1.9, 84.1, and 89.8 µg/dl, respectively. The mean serum calcium and magnesium during the three trimesters of pregnancy were not significantly different from that in the umbilical cord blood, while the mean serum zinc and iron in the umbilical cord blood were significantly different (p<0.05) in the three trimester of pregnancy. The mean birth weight of neonates was 3.1 kg and 12% of neonates showed low birth weight. Our findings showed that, except magnesium, the profile of other biochemical variables, namely, calcium, zinc and iron in the umbilical cord blood

The aim of this study was to determine whether homocysteine (hcy) concentrations in embryo culture media correlate with pregnancy outcome in assisted reproductive technology (ART) cycles. Forty patients who underwent single embryo transfer at the infertility clinic of a tertiary care center were recruited for this case-control study. Spent embryo culture media from all patients were collected after single embryo transfer on day 3 (n = 40). Hcy concentrations in embryo culture media were analyzed by enzyme cycling method. Patients were grouped according to the diagnosis of a clinical pregnancy. Sixteen patients were pregnant while 24 patients failed to achieve conception. Mean Hcy levels in the culture media were significantly different between the groups (p < 0.003), as 4.58 ± 1.31 μmol/l in the non-pregnant group and 3.37 ± 0.92 μmol/l in the pregnant group. Receiver operator curve analysis for determining the diagnostic potential of Hcy for pregnancy revealed an area under the curve of 0.792 (confidence interval: 0.65-0.94; p < 0.05). A cut-off value of 3.53 μmol/l was determined with a sensitivity of 83.3%, and a specificity of 68.8%. Lower hcy levels were associated with a better chance of pregnancy and better embryo grades. Hcy may be introduced as an individual metabolomic profiling marker for embryos.

Background The importance of maternal sanitation behaviour during pregnancy for birth outcomes remains unclear. Poor sanitation practices can promote infection and induce stress during pregnancy and may contribute to adverse pregnancy outcomes (APOs). We aimed to assess whether poor sanitation practices were associated with increased risk of APOs such as preterm birth and low birth weight in a population-based study in rural India. Methods and Findings A prospective cohort of pregnant women (n = 670) in their first trimester of pregnancy was enrolled and followed until birth. Socio-demographic, clinical, and anthropometric factors, along with access to toilets and sanitation practices, were recorded at enrolment (12th week of gestation). A trained community health volunteer conducted home visits to ensure retention in the study and learn about study outcomes during the course of pregnancy. Unadjusted odds ratios (ORs) and adjusted odds ratios (AORs) and 95% confidence intervals for APOs were estimated by logistic regression models. Of the 667 women who were retained at the end of the study, 58.2% practiced open defecation and 25.7% experienced APOs, including 130 (19.4%) preterm births, 95 (14.2%) births with low birth weight, 11 (1.7%) spontaneous abortions, and six (0.9%) stillbirths. Unadjusted ORs for APOs (OR: 2.53; 95% CI: 1.72–3.71), preterm birth (OR: 2.36; 95% CI: 1.54–3.62), and low birth weight (OR: 2.00; 95% CI: 1.24–3.23) were found to be significantly associated with open defecation practices. After adjustment for potential confounders such as maternal socio-demographic and clinical factors, open defecation was still significantly associated with increased odds of APOs (AOR: 2.38; 95% CI: 1.49–3.80) and preterm birth (AOR: 2.22; 95% CI: 1.29–3.79) but not low birth weight (AOR: 1.61; 95% CI: 0.94–2.73). The association between APOs and open defecation was independent of poverty and caste. Even though we accounted for several key

Preeclampsia in Ecuador is an understudied subject since available epidemiological data are scarce. The aim of this study was to describe perinatal outcomes among singleton pregnancies complicated with preeclampsia and eclampsia in a sample of low-income Ecuadorian women. Pregnant women complicated with preeclampsia (mild and severe) and eclampsia (defined according to criteria of the ACOG) delivering at the Enrique C. Sotomayor Obstetrics and Gynecology Hospital, Guayaquil, Ecuador were surveyed with a structured questionnaire containing maternal (socio-demographic) and neonatal data. Perinatal outcomes were compared according to severity of clinical presentation. A total of 163 women with preeclampsia [mild (23.9%), severe (68.7%) and eclampsia (7.4%)] were surveyed. Perinatal mortality and stillbirth rate was similar among studied groups (mild vs. severe preeclampsia/eclampsia cases). However, severe cases displayed higher rates of adverse perinatal outcomes: lower birth Apgar scores, more preterm births, and more low birth weight and small for gestational age infants. Caesarean-section rate and the number of admissions to intensive or intermediate neonatal care were higher in severe cases. A similar trend was found when analysis excluded preterm gestations. In conclusion, in this specific low-income Ecuadorian population perinatal outcome was adverse in pregnancies complicated with severe preeclampsia/eclampsia.

Iron deficiency is the most common nutritional deficiency globally. Children and women of reproductive age are at a particular risk of iron deficiency. Anaemia during pregnancy is a specific risk factor for adverse maternal and perinatal outcomes. The objective of this review was to assess the impact of routine iron supplementation on maternal anaemia and perinatal outcomes. A literature search was conducted for published randomised and quasi-randomised trials on PubMed and the Cochrane Library. Only those studies were included in the review that assessed the preventive effect of iron supplementation during pregnancy. Data from selected studies were double abstracted in a standardised excel sheet. The studies were graded according to study design, limitations, intervention specifics and outcome effects. Meta-analyses were conducted where data were available from more than one study for an outcome. After screening 5209 titles, 30 studies were selected for inclusion in this review. Daily iron supplementation resulted in 69% reduction in incidence of anaemia at term in the intervention group compared with control [relative risk (RR) 0.31 [95% confidence interval (CI) 0.22, 0.44

Background/Aims Anti-tumor necrosis factor drugs (anti-TNF) and thiopurines are important treatment options in patients with inflammatory bowel disease (IBD), including during pregnancy. However, there are limited data on the benefit/risk profile of anti-TNF and thiopurines during pregnancy in Asia. The aim of this study was to analyze pregnancy outcomes of female Japanese IBD patients treated with anti-TNF and/or thiopurines. Methods This cross-sectional study assessed pregnancy outcomes in 72 women with IBD. Pregnancy outcomes were compared among 31 pregnancies without exposure to infliximab (IFX), adalimumab (ADA), or thiopurines; 24 pregnancies with exposure to anti-TNF treatment (23 IFX, 1 ADA); 7 pregnancies with exposure to thiopurines alone; and 10 pregnancies with exposure to both IFX and thiopurines. Results Thirty-five of the 41 pregnancies (85.3%) that were exposed to anti-TNF treatment and/or thiopurines resulted in live births after a median gestational period of 38 weeks. Of the 35 live births, 3 involved premature deliveries; 7, low birth weight; and 1, a congenital abnormality. There were 6 spontaneous abortions in pregnancies that were exposed to anti-TNF treatment (17.7%). Pregnancy outcomes among the 4 groups were similar, except for the rate of spontaneous abortions (P =0.037). Conclusions Exposure to anti-TNF treatment or thiopurines during pregnancy was not related to a higher incidence of adverse pregnancy outcomes in Japanese IBD patients except for spontaneous abortion.

Purpose Moyamoya disease (MMD) occurs predominantly in Korean and Japanese women. The aim of this study was to investigate clinical features and pregnancy outcomes in women with MMD. Materials and Methods We conducted a retrospective chart review of women with MMD who visited our Department of Obstetrics and Gynecology between January 2005 and October 2013. For all study subjects, clinical features, demographic characteristics, and perinatal outcomes were recorded. Results We identified 28 pregnancies in 22 patients who had been diagnosed with MMD. The mean maternal age at delivery was 31.9±3.5 years old. The mean gestational age at delivery was 38.0±0.9 weeks. Among the 28 pregnancies, 25 (92.5%) underwent cesarean section; 19 (76.0%) of them were performed under regional anesthesia and six (24.0%) under general anesthesia. The mean newborn weight was 3233.7±348.2 g. The 5-minute Apgar score in 85% of the newborns was higher than 8, with no other apparent complications. During the puerperal period, transient ischemic attack symptom or seizure occurred in 4 cases, although patients recovered within a few days. Conclusion For pregnant women with MMD, it is important to control blood pressure and prevent hyperventilation during the intrapartum period, and the best methods of delivery and anesthesia should be considered to avoid unfavorable sequelae. Additionally, a multidisciplinary approach (i.e., neurosurgery) is necessary to constantly manage underlying diseases. PMID:25837187

We review the epidemiological literature on the possible impact of chemical and physical factors on pregnancy outcome. Effects of in-utero exposures on child health are not considered here. The highest levels of evidence concern the effects of passive smoking (on fetal growth), of lead (pregnancy-induced hypertension, fetal growth), of some Polychlorinated Biphenyls (PCB; on fetal growth) and, to a lesser extent, of atmospheric pollutants (on fetal growth and preterm delivery). For the other compounds, in particular non-persistent chemicals, the literature, which is generally based on poor exposure assessment, is less informative. In conclusion, the last decades have witnessed the development of mother-child cohorts in which exposure biomarkers have been assayed, allowing a large number of publications. For some persistent compounds, for which efficient exposure assessment approaches have been used, the literature indicates a likely impact on pregnancy outcomes. With the exception of air pollutants, the literature on non-persistent compounds is little conclusive; the assay of exposure biomarkers in repeated biological samples collected at relevant time points could help further increase knowledge regarding any health impact.

Although there is now considerable experience in obtaining sperm from a cadaver, there is little or no published data regarding pregnancy, birth and long-term childhood health and development outcomes when posthumous sperm is used in in vitro fertilisation (IVF). We report the results from treatment of four women undergoing IVF treatment using posthumously acquired human sperm from their deceased partners. In all cases, testicular tissue was obtained in a mortuary setting, and the duration from death to posthumous sperm retrieval ranged from 12 to 48 h. The age of women treated ranged from 31 to 41 years. Fertilization rates ranged from 40 to 100%. Singleton pregnancies were obtained for each of the four women. One pregnancy was complicated by preterm birth at 31 weeks; the other three delivered at term. One baby was growth restricted but morphologically normal; the other children had term birthweights in the normal range. All four children were have shown normal health and developmental outcomes, with the follow-up ranging from 1 to 7 years.

STUDY OBJECTIVE--The aim was to obtain quantitative information from published data on the potential association between video display terminal (VDT) use during pregnancy and the outcome. DESIGN--Results of nine published case-control studies (or cohort studies analysed as case-control) on the relation between VDT exposure during pregnancy and the outcome were sought by reviewing reference lists in relevant reports and by conducting manual and computer searches of the reports published in English. MEASUREMENTS AND MAIN RESULTS--The nine reviewed reports included information on about 9000 cases of spontaneous miscarriages, 1500 of low birth weight, 2000 of congenital malformation, and 50,000 controls. The results of these studies on each outcome of pregnancy examined were reduced to a single 2 x 2 table (cases/controls--exposed/unexposed). Pooled odds ratio (OR) estimates were computed separately for miscarriage, low birth weight, and congenital malformation. Seven studies analysed the relation between VDT exposure in pregnancy and the risk of miscarriage: the estimates' crude OR of spontaneous abortion ranged from 0.9-1.2 and the pooled OR was 1.0 (95% confidence interval (CI) 0.9, 1.0). No consistent evidence of increasing risk with duration of exposure to VDT was found. Two studies analysed the relation between VDT use and risk of having a low birth weight infant: the OR estimates in the individual studies were 1.0 and 1.1. Likewise, no relation emerged from the five studies providing information on congenital malformations and VDT use: the pooled OR was 1.0 (95% CI 0.9, 1.2). No specific malformation pattern emerged. CONCLUSIONS--This meta-analysis provides reassuring evidence on the absence of any major risk of adverse pregnancy outcome as a result of exposure to a VDT. With the number of cases reviewed, it was possible to exclude excess risk of 20% for spontaneous abortion, low birth weight, and congenital malformations. PMID:8228759

Background Numerous studies have examined associations between air pollution and pregnancy outcomes, but most have been restricted to urban populations living near monitors. Objectives We examined the association between pregnancy outcomes and fine particulate matter in a large national study including urban and rural areas. Methods Analyses were based on approximately 3 million singleton live births in Canada between 1999 and 2008. Exposures to PM2.5 (particles of median aerodynamic diameter ≤ 2.5 μm) were assigned by mapping the mother’s postal code to a monthly surface based on a national land use regression model that incorporated observations from fixed-site monitoring stations and satellite-derived estimates of PM2.5. Generalized estimating equations were used to examine the association between PM2.5 and preterm birth (gestational age < 37 weeks), term low birth weight (< 2,500 g), small for gestational age (SGA; < 10th percentile of birth weight for gestational age), and term birth weight, adjusting for individual covariates and neighborhood socioeconomic status (SES). Results In fully adjusted models, a 10-μg/m3 increase in PM2.5 over the entire pregnancy was associated with SGA (odds ratio = 1.04; 95% CI 1.01, 1.07) and reduced term birth weight (–20.5 g; 95% CI –24.7, –16.4). Associations varied across subgroups based on maternal place of birth and period (1999–2003 vs. 2004–2008). Conclusions This study, based on approximately 3 million births across Canada and employing PM2.5 estimates from a national spatiotemporal model, provides further evidence linking PM2.5 and pregnancy outcomes.

Objective To determine: 1) if periodontal treatment in pregnant women before 21 weeks of gestation alters levels of inflammatory mediators in serum; and 2) if changes in these mediators are associated with birth outcomes. Methods 823 pregnant women with periodontitis were randomly assigned to receive scaling and root planing before 21 weeks of gestation or after delivery. Serum obtained between 13 weeks and 16 weeks 6 days (study baseline) and 29–32 weeks gestation was analyzed for C-reactive protein, prostaglandin E2, matrix metalloproteinase-9, fibrinogen, endotoxin, interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor-α. Cox regression, multiple linear regression, t-tests, chi-square and Fisher’s exact tests were used to examine associations between the biomarkers, periodontal treatment, and gestational age at delivery and birthweight. Results 796 women had baseline serum data; 620 had baseline and follow-up serum and birth data. Periodontal treatment did not significantly alter the level of any biomarker (P>0.05). Neither baseline levels nor change from baseline in any biomarker was significantly associated with preterm birth or infant birthweight (P>0.05). In treatment subjects, change in endotoxin was negatively associated with change in probing depth (P<0.05). Conclusions Non-surgical mechanical periodontal treatment in pregnant women delivered before 21 weeks of gestation did not reduce systemic (serum) markers of inflammation. In pregnant women with periodontitis, levels of these markers at 13–17 weeks and 29–32 weeks gestation were not associated with risk for preterm birth or with infant birthweight. PMID:19905943

The effects of zinc supplementation on levels of various blood constituents and the outcome of pregnancy in 213 Hispanic women attending a prenatal clinic in Los Angeles was assessed in this double-blind study. The women were randomized into either a control (C) or a zinc-supplemented (Z) group and received similar vitamin and mineral supplements except that 20 mg zinc was added to the Z group's capsules. At the final interview, women (C + Z) with low serum Zn levels (less than or equal to 53 micrograms/dl) had higher (p less than 0.01) mean ribonuclease activity and lower (p less than 0.01) mean delta-aminolevulinic acid dehydratase activity than women with acceptable serum zinc levels. The incidence of pregnancy-induced hypertension was higher (p less than 0.003) in the C than in the Z group, but pregnancy-induced hypertension was not associated with low serum zinc levels at either the initial or final interview. The expected increase in serum copper levels was greater (less than 0.001) in women with pregnancy-induced hypertension (C + Z) than in normotensives. Except for pregnancy-induced hypertension, there was a higher incidence of abnormal outcomes of pregnancy in the noncompliers than in the compliers (C + Z).

Objective Nonadherence in diabetes is a problem leading to wasted resources and preventable deaths each year. Remedies for diminishing nonadherence are many but marginally effective, and outcomes remain suboptimal. Aim The aim of this study was to test a new iOS “app”, PatientPartner. Derived from complexity theory, this novel technology has been extensively used in other fields; this is the first trial in a patient population. Methods Physicians referred patients who were “severely non-adherent” with HbA1c levels >8. After consent and random assignment (n=107), subjects in the intervention group were immersed in the 12-min PatientPartner game, which assesses and trains subjects on parameters of thinking that are critical for good decision making in health care: information management, stress coping, and health strategies. The control group did not play PatientPartner. All subjects were called each week for 3 weeks and self-reported on their medication adherence, diet, and exercise. Baseline and 3-month post-intervention HbA1c levels were recorded for the intervention group. Results Although the control group showed no difference on any measures at 3 weeks, the intervention group reported significant mean percentage improvements on all measures: medication adherence (57%, standard deviation [SD] 18%–96%, SD 9), diet (50%, SD 33%–75%, SD 28), and exercise (29%, SD 31%–43%, SD 33). At 3 months, the mean HbA1c levels in the intervention group were significantly lower (9.6) than baseline (10.7). Conclusion Many programs to improve adherence have been proved to be expensive and marginally effective. Therefore, improvements from the single use of a 12-min-long “app” are noteworthy. This is the first ever randomized, controlled trial to demonstrate that an “app” can impact the gold standard biological marker, HbA1c, in diabetes. PMID:28243070

BACKGROUND: Alport syndrome is a genetic disease that progresses to chronic kidney failure, with X-linked, autosomal dominant or autosomal recessive type of inheritance. Women are generally carriers of the mutation and have a milder form of the disease. During pregnancy, they have an increased risk of impaired kidney function and preeclampsia. CASE PRESENTATION: A 27-year old woman, gravida 1, para 0, in her 23rd gestational week came to the outpatient unit of the University Clinic of Nephrology for the first time because of slowly progressing proteinuria and Alport syndrome. She was admitted to the gynaecological ward in her 29th gw for proteinuria which increased from 3.8 g/day up to 20 g/day and the serum creatinine increased to 120- 150 micromol/l. She was delivered in the 30th gestational week due to obstetrical indications with a cesarian section and delivered a baby with a birth weight of 880 g. After delivery, proteinuria decreased to 2 g/d within 2 months and an angiotensin-converting enzyme inhibitor (ACEI) was started. Her second pregnancy, after 2 years, had an uneventful course and she delivered a healthy baby weighing 3000 g in the 39th week. Six months after the second delivery, her renal function remained normal and her proteinuria was 2 g/d. CONCLUSIONS: Pre-pregnancy counselling and frequent controls during pregnancy are necessary for women with Alport syndrome, as well as regular monitoring after delivery. Recent reports are more in favour of good pregnancy and nephrological outcomes in women with Alport syndrome when renal disease is not advanced. PMID:27703570

Background: The association between the previous history of endometriosis and obstetric outcomes is still ambiguous. This study aimed to evaluate the effects of previous history of operatively diagnosed endometriosis on pregnancy outcomes. Methods: A total of 98 primiparous women who had been diagnosed with endometriosis by previous laparoscopic surgery were included in this retrospective cohort study. Pregnancy outcomes were compared between these women (study group) who had a live birth and 300 women without endometriosis (control group) who had a live birth. In the study group, the pregnancy outcomes of 74 women who conceived naturally (no assisted reproductive technology [ART] subgroup) were simultaneously compared with 24 women who conceived by ART (ART subgroup). Results: Miscarriage was observed in 23 of 98 women with endometriosis (23.5%). There were 75 women who had a live birth after laparoscopic diagnosis of endometriosis in the study group eventually. On multivariate analysis, the postpartum hemorrhage rate increased significantly in the study group when compared with the control group (adjusted odds ratio: 2.265, 95% confidence interval: 1.062, 4.872; P = 0.034). There was an upward tendency of developing other pregnancy-related complications, such as preterm birth, placental abruption, placenta previa, cesarean section, fetal distress/anemia, and others in the study group than in the control group. However, the differences showed no statistical significance. Within the study group, the occurrence rate of postpartum hemorrhage and preterm birth was both higher in the ART subgroup than in the no ART subgroup. The differences both had statistical significance (44.4% vs. 17.5%, P = 0.024 and 27.8% vs. 1.8%, P = 0.010, respectively). At the same time, median (interquartile range) for gestational age at delivery in the ART subgroup was significantly shorter than that in the no ART subgroup (38 weeks [36–39 weeks] vs. 39 weeks [38–40 weeks]; P = 0

Antiphospholipid syndrome (APS) is the association of antiphospholipid antibodies with thromboses and/or obstetric morbidity. Obstetric morbidity includes recurrent first trimester loss, stillbirth, intrauterine death, preeclam-psia, premature birth and fetal growth restriction. Although current treatment regimens including aspirin and low-molecular weight heparin have improved pregnancy outcomes, 30% of affected women have pregnancy complica-tions. Women with APS are therefore high-risk pregnancies who should be monitored in specialist centres according to international standards.

Introduction: Hypertensive disorders complicating pregnancy seriously endanger the safety of the mother and fetus during pregnancy. Very few studies have explored hypertensive disorders of pregnancy in India, even though this disease has been associated with adverse maternal and perinatal outcomes. This study aimed to analyze the disease pattern and risk factors associated with the disorder and assess the maternal and fetal outcomes in cases of hypertensive disorders of pregnancy. Subjects and methods: This case-control study was carried out over 1 year from 2011 to 2012 at the Department of Obstetrics and Gynecology, King George’s Medical University, Lucknow, Uttar Pradesh, India. A total of 149 patients were enrolled in the study. As seven were lost to follow-up, analysis was carried out on 142 cases. Patients were further classified according to the National High Blood Pressure Education Program Working Group (2000) as having mild preeclampsia (65 cases), severe preeclampsia (32 cases), or eclampsia (45 cases). Thirty-one healthy pregnant non-hypertensive women were enrolled into the study as controls. Results: The most common manifestation was edema, seen in 90% of cases. Proteinuria was also relatively common, 26.76% of patients with proteinuria of ≥300 mg/24 hours, 47.88% with proteinuria of ≥2 g/24 hours, and 25.35% with a urinary protein excretion of 3–5 g/24 hours. Central nervous system involvement was observed in 42.2% of cases, elevated bilirubin levels in 47.0%, visual symptoms in 6.4%, vaginal bleeding in 11.3%, and HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome was reported in 2.80%. Maternal deaths occurred in 2.8% of cases, all of which were from the eclampsia group. Stillbirths occurred in 16.9% of cases, and overall neonatal death observed in 4.23% of cases. Conclusion: Women with hypertensive disorders of pregnancy were more prone to adverse maternal and fetal outcomes than normotensive pregnant women, but we

The objective of this prospective cohort study was to determine the sensitivity, specificity, accuracy, and predictive value of twin pregnancy diagnosis by rectal palpation and to examine fetal survival, culling rates, and gestational lengths of cows diagnosed with twins. In this prospective study, 5309 cows on 14 farms in California were followed from pregnancy diagnosis to subsequent abortion or calving. The average sensitivity, specificity, accuracy, and predictive value of twin pregnancy diagnosis were 49.3%, 99.4%, 96.0%, and 86.1%, respectively. The abortion rate for single pregnancies of 12.0% differed significantly from those for bicornual twin pregnancies and unicornual twin pregnancies of 26.2% and 32.4%, respectively (P < 0.05). The early calf mortality between cows calving with singles (3.2%) and twins (15.7%) were significantly different (P < 0.005). The difference in fetal survival between single pregnancies and all twin pregnancies resulted in 0.42 and 0.29 viable heifers per pregnancy, respectively. The average gestation for single, bicornual, and unicornual pregnancies that did not abort before drying-off was 278, 272, and 270 days, respectively. Results of this study show that there is an increased fetal wastage associated with twin pregnancies and suggest a need for further research exploring management strategies for cows carrying twins.

Objective In East Asia the recently increased number of marriages in response to pregnancy is an important social issue. This study evaluated the association of marriage preceded by pregnancy (bridal pregnancy) with obstetric outcomes among live births in Korea. Methods In this population-based study, 1,152,593 first singleton births were evaluated from data registered in the national birth registration database from 2004 to 2008 in Korea. In the study population, the pregnancy outcomes among live births from the bridal pregnancy group (N = 62,590) were compared with the outcomes of the post-marital pregnancy group (N = 564,749), composed of women who gave birth after 10 months but before 24 months of marriage. The variables preterm birth (PTB; <37 weeks gestation) and low birth weight (LBW; <2.5 kg) were used to determine the primary outcome. The adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated after controlling for socio-demographic factors. Results The socio-demographic factors among the bridal pregnancy group were associated with a social disadvantage and particular risk factors. In the subgroup analyses of maternal age, differences in adverse pregnancy outcomes from bridal pregnancy were identified between women in the following age group: (i) ≤19, (ii) 20–39, and (iii) ≥40 years. After the multivariate analysis, the aORs for each age group were 1.47 (95% CI: 1.15–1.89), 1.76 (1.70–1.83), and 1.13 (0.77–1.66), respectively, for PTB and 0.92 (0.70–1.21), 1.60 (1.53–1.66), and 1.11 (0.71–1.74), respectively, for LBW. In the adjusted logistic regression models, bridal pregnancy was associated with PTB (1.76, 1.69–1.82) and LBW (1.53, 1.48–1.59). Conclusion Pregnancy outcomes among live births from bridal pregnancies are associated with higher risks for PTB and LBW in Korea. PMID:25105842

Maternal intake of licorice from dietary sources has been associated with adverse maternal and fetal outcomes. We prospectively studied the outcome of 185 singleton pregnancies who took over-the-counter or naturopathic formulations containing licorice during their pregnancy, and 370 age-matched singleton pregnant controls that were not exposed to any potential teratogen. The indication in 56.8% of the women taking licorice was for cough and cold control, with the maximum dose of 2104 mg/day and exposure occurring between the 4th day and 25th week of gestation. The rate of stillbirths was marginally higher among women who took licorice than those who did not (OR = 7.9; 95% CI 0.9-71.5; p = 0.048), and significantly higher when compared to the general population in the Republic of Korea (OR = 13.3; 95% CI 4.9-35.8; p < 0.001). Other fetal outcomes assessed in the study were similar between the two study groups, e.g., the OR of major malformations was 3.9 (95% CI 0.4-43.5; p = 0.27). In conclusion, the present study suggests that licorice is not a major teratogen. However, whether licorice may increase the risk of stillbirths requires careful consideration in further studies with a larger sample size.

Abstract The aim of our study was to compare the clinical characteristics of fetal and neonatal outcomes in twin pregnancies between women with preeclampsia (PE) and those with normotension in a Chinese population. There were 143 preeclamptic women and 367 normotensive women with twin pregnancies included in this retrospective case–control study. The baseline characteristics and perinatal outcomes were collected and compared between the groups. Multiple logistic regression and linear regression were used to assess the correlations between PE and the outcomes. Significant increases were observed in the frequencies of preterm delivery (OR = 2.75, P < 0.001), iatrogenic preterm birth (OR = 3.52, P < 0.001), and IUGR (OR = 2.94, P = 0.001) in the PE group, and the PE group had more than a 2-fold risk of adverse neonatal outcomes. Preeclamptic twin neonates had lower birth weights (β = −147.34, P = 0.005; β = −169.47, P = 0.001). The comparison on the discordance of intertwin weight was not significantly different. Twin pregnancies with PE are associated with worse perinatal outcomes. The adverse outcomes of preeclamptic twin pregnancies may be associated with lower birth weights rather than the discordance of the intertwin weight, which requires further confirmation. The results may provide helpful references for better clinical assessments, evaluations of prognosis, and a deeper understanding of preeclamptic twin pregnancies. PMID:27787375
Infection with Neospora caninum stimulates host cell-mediated immune responses, which may be responsible for placental damage leading to bovine abortion. The aim of this study was to compare immune responses in the bovine placenta, following experimental infection in different stages of pregnancy. Placentomes were examined by immunohistochemistry and inflammation in early gestation was generally moderate to severe, particularly in the placentas carrying non-viable foetuses, whereas it was milder in later stages, mainly characterised by the presence of CD3+, CD4+ and γδ T-cells. This distinctive cellular immune response may explain the milder clinical outcome observed when animals are infected in later gestation. PMID:24484200

Objective Selective serotonin reuptake inhibitor (SSRI) use during pregnancy incurs a low absolute risk for major malformations; however, other adverse outcomes have been reported. Major depression also affects reproductive outcomes. This study examined whether 1) minor physical anomalies, 2) maternal weight gain and infant birth weight, 3) preterm birth, and 4) neonatal adaptation are affected by SSRI or depression exposure. Method This prospective observational investigation included maternal assessments at 20, 30, and 36 weeks of gestation. Neonatal outcomes were obtained by blinded review of delivery records and infant examinations. Pregnant women (N=238) were categorized into three mutually exclusive exposure groups: 1) no SSRI, no depression (N=131); 2) SSRI exposure (N=71), either continuous (N=48) or partial (N=23); and 3) major depressive disorder (N=36), either continuous (N=14) or partial (N=22). The mean depressive symptom level of the group with continuous depression and no SSRI exposure was significantly greater than for all other groups, demonstrating the expected treatment effect of SSRIs. Main outcomes were minor physical anomalies, maternal weight gain, infant birth weight, pregnancy duration, and neonatal characteristics. Results Infants exposed to either SSRIs or depression continuously across gestation were more likely to be born preterm than infants with partial or no exposure. Neither SSRI nor depression exposure increased risk for minor physical anomalies or reduced maternal weight gain. Mean infant birth weights were equivalent. Other neonatal outcomes were similar, except 5-minute Apgar scores. Conclusions For depressed pregnant women, both continuous SSRI exposure and continuous untreated depression were associated with preterm birth rates exceeding 20%. PMID:19289451

Women with chronic hypertension are at increased risk of maternal and fetal morbidity and mortality. We have previously characterized the stroke-prone spontaneously hypertensive rat (SHRSP) as a model of deficient uterine artery function and adverse pregnancy outcome compared with the control Wistar–Kyoto. The activation of the immune system plays a role in hypertension and adverse pregnancy outcome. Therefore, we investigated the role of tumor necrosis factor-α in the SHRSP phenotype in an intervention study using etanercept (0.8 mg/kg SC) at gestational days 0, 6, 12, and 18 in pregnant SHRSP compared with vehicle-treated controls (n=6). Etanercept treatment significantly lowered systolic blood pressure after gestational day 12 and increased litter size in SHRSP. At gestational day 18, etanercept improved the function of uterine arteries from pregnant SHRSP normalizing the contractile response and increasing endothelium-dependent relaxation, resulting in increased pregnancy-dependent diastolic blood flow in the uterine arteries. We identified that the source of excess tumor necrosis factor-α in the SHRSP was a pregnancy-dependent increase in peripheral and placental CD3– CD161+ natural killer cells. Etanercept treatment also had effects on placental CD161+ cells by reducing the expression of CD161 receptor, which was associated with a decrease in cytotoxic granzyme B expression. Etanercept treatment improves maternal blood pressure, pregnancy outcome, and uterine artery function in SHRSP by antagonizing signaling from excess tumor necrosis factor-α production and the reduction of granzyme B expression in CD161+ natural killer cells in SHRSP.

Background Only few studies have assessed safety of in utero exposure to glatiramer acetate (GA). Following a previous study assessing the safety of interferon beta (IFNB) pregnancy exposure in multiple sclerosis (MS), we aimed to assess pregnancy and fetal outcomes after in utero exposure to GA, using the same dataset, with a specific focus on the risk of spontaneous abortion. Materials and methods We recruited MS patients, prospectively followed-up in 21 Italian MS Centres, for whom a pregnancy was recorded in the period 2002–2008. Patients were divided into 2 groups: drug-exposed pregnancies (EP: suspension of the drug less than 4 weeks from conception); non-exposed pregnancies (NEP: suspension of the drug at least 4 weeks from conception or never treated pregnancies). All the patients were administered a structured interview which gathered detailed information on pregnancy course and outcomes, as well as on possible confounders. Multivariate logistic and linear models were used for treatment comparisons. Results Data on 423 pregnancies were collected, 17 were classified as EP to GA, 88 as EP to IFNB, 318 as NEP. Pregnancies resulted in 16 live births in the GA EP, 75 live births in the IFNB EP, 295 live births in the NEP. GA exposure was not significantly associated with an increased risk of spontaneous abortion (OR = 0.44;95% CI 0.044-4.51;p = 0.49). Mean birth weight and length were not significantly different in pregnancies exposed to GA than in non exposed pregnancies (p = 0.751). The frequency of preterm delivery, observed in 4 subjects exposed to GA (25% of full term deliveries), was not significantly higher in pregnancies exposed to GA than in those non exposed (p > 0.735). These findings were confirmed in the multivariate analysis. There were neither major complications nor malformations after GA exposure. Conclusions Data in our cohort show that mother’s GA exposure is not associated with a higher frequency of spontaneous abortion

OBJECTIVES: A large prospective clinical trial was conducted to compare the efficacy of single dose uFSH and clomiphene citrate combination with clomiphene citrate alone for ovulation induction to improve the pregnancy rate. MATERIALS AND METHODS: The study was a randomized, prospective clinical trial. Totally, 1527 infertile women (4381 cycles) with polycystic ovarian syndrome (PCOS) (n=911/2573 cycles) and unexplained infertility (n=616/1808 cycles) were randomized into two groups. Group A received single dose of uFSH on D3 of menstrual cycle along with clomiphene. Group B received clomiphene only for ovulation induction. We compared the pregnancy rate and miscarriage rate between two groups. RESULTS: Group A had a pregnancy rate of 17% compared to 8.3% of Group B which was significantly higher (P=0.0001). The miscarriage rate was 11% in Group A and 10% in Group B which was not significant (P=0.99). Pregnancy rates in PCOS women were 22% in Group A and 9.3% in Group B which shows significantly higher pregnancy rate (P=0.0001) in anovulatory infertility. But in unexplained infertility, there was no significant difference in pregnancy rate between Group A (11%) and Group B(6.3%). Miscarriage rates were 8.8% and 9.5% in Group A and Group B, respectively, in PCOS women and 14% and 13% in women with unexplained infertility. CONCLUSION: Addition of single dose of uFSH improves pregnancy outcome particularly in anovulatory infertility (WHO II). Correction of unexplained infertility may need more than simple correction of possible subtle ovulatory effect. PMID:21209751

In the literature, there is growing evidence that subfertile patients who conceived after infertility treatments have an increased risk of pregnancy and perinatal complications and this is particularly true for patients who conceived through use of high technology infertility treatments. Moreover, high technology infertility treatments include many concomitant clinical and biological risk factors. This review aims to summarize in a systematic fashion the current evidence regarding the relative effect of the different procedures for high technology infertility treatments on the risk of adverse pregnancy and perinatal outcome. A literature search up to August 2016 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science and Google Scholar and an evidence-based hierarchy was used to determine which articles to include and analyze. Data on prepregnancy maternal factors, low technology interventions, specific procedures for male factor, ovarian tissue/ovary and uterus transplantation, and chromosomal abnormalities and malformations of the offspring were excluded. The available evidences were analyzed assessing the level and the quality of evidence according to the Oxford Centre for Evidence-Based Medicine guidelines and the Grading of Recommendations Assessment, Development, and Evaluation system, respectively. Current review highlights that every single procedure of high technology infertility treatments can play a crucial role in increasing the risk of pregnancy and perinatal complications. Due to the suboptimal level and quality of the current evidence, further well-designed studies are needed.

This study aimed to identify the factors associated with induced abortion in the first pregnancy in young women and in the first time young men got their partners pregnant. The methodology was a household survey with face-to-face interviews in a probabilistic sample in three stages with 4,634 subjects, aged 18 to 24 years of age residing in the cities of Salvador, Rio de Janeiro, and Porto Alegre, Brazil. Logistic regression analysis was used with a hierarchical strategy for entering variables into the model. Abortion was the reported outcome of the first pregnancy for 16.7% of the women and 45.9% of the men (in relation to their partners). Key factors associated with abortion included higher schooling and the occasional nature of the relationship with the male or female partner in the respective pregnancy. Inclusion of males in the study provided new elements for understanding the abortion phenomenon, including in the gender issues in discussion of the theme. The authors recommend greater public investment to warrant access to information and means for young people to achieve their reproductive plans in a security and healthy way, respecting their sexual and reproductive rights.

Functional dysphonia (FD) refers to a voice problem in the absence of a physical condition. It is a multifaceted voice disorder. There is no consensus with regard to its definition and inclusion criteria for diagnosis. FD has many predisposing and precipitating factors, which may include genetic susceptibility, psychological traits, and the vocal behavior itself. The assessment of voice disorders should be multidimensional. In addition to the clinical examination, auditory-perceptual, acoustic, and self-assessment analyses are very important. Self-assessment was introduced in the field of voice 25 years ago and has produced a major impact in the clinical and scientific scenario. The choice of treatment for FD is vocal rehabilitation by means of direct therapy; however, compliance has been an issue, except for cases of functional aphonia or when an intensive training is administered. Nevertheless, there are currently no controlled studies that have explored the different options of treatment regimens for these patients. Strategies to improve patient outcome involve proper multidisciplinary diagnosis in order to exclude neurological and psychiatric disorders, careful voice documentation with quantitative measurement and qualitative description of the vocal deviation for comparison after treatment, acoustic evaluation to gather data on the mechanism involved in voice production, self-assessment questionnaires to map the impact of the voice problem on the basis of the patient’s perspective, referral to psychological evaluation in cases of suspected clinical anxiety and/or depression, identification of dysfunctional coping strategies, self-regulation data to assist patients with their vocal load, and direct and intensive vocal rehabilitation to reduce psychological resistance and to reassure patient’s recovery. An international multicentric effort, involving a large population of voice-disordered patients with no physical pathology, could produce enough data for

Twenty-six-year-old Ebstein's anomaly patient, who had failed both biventricular and one-and-a-half repair, underwent right ventricle exclusion and Fontan operation. She completed pregnancy and delivery owing to the excellent long-term clinical course. Although the caesarean section was performed due to symptoms of heart failure on the gestational age of 32+6 weeks, preterm delivery was agreeable with neonatology support. In Korea, there has not yet been a case of pregnancy and delivery of functional single ventricle patient because most patients have been discouraged from getting pregnant. However, functional single ventricle patient can endure pregnancy and delivery, if valve function and ventricular contractility, status of Fontan pathway and absence of arrhythmia predict favorable outcome as presented in this case. Although the patient maintained her pregnancy without anticoagulation owing to laminar flow in the Fontan pathway and absence of thromboembolic event, anticoagulation should be considered, weighing the benefits and risks during the pregnancy.

There is increasing incidence and prevalence of chronic kidney disease worldwide. The developing countries including Nigeria are facing greater challenges because of the prevailing poverty and high burden of infectious diseases. There are various prevalent co-morbid conditions that influence and are influenced by the status of the kidney function of the patient. These conditions pose some peculiar challenges and management of the challenges will determine the outcome. The aim of this report is to highlight the chalIenges of pregnancy in women with chronic kidney disease and possible outcome. We report a 24 years Nigerian woman diagnosed with chronic kidney disease who presented with 10 weeks gestation and deteriorating kidney function. Her management was associated with various challenges including non adherance to medications and not regular to follow up visits. She later developed ecclampsia and had intra uterine fetal death. She had various interventional measures including haemodialysis. She recovered kidney function appreciably but has defaulted follow up since discharge.

Abstract The aim of this study was to evaluate the influence of I-131 therapy on pregnancy outcome in patients that received therapeutic I-131 doses for thyroid cancer in Taiwan. This nationwide population-based cohort study was based on data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database. We identified 11,708 women with thyroid cancer (≥15 and ≤50 years of age) by International Classification of Diseases, Ninth Revision, Clinical Modification codes. Patients were divided into 2 cohorts: I-131 therapy cohort and non-I-131 therapy cohort. The mean follow-up period was 6.08 years for the I-131 cohort and 6.87 years for the non-I-131 cohort. The case cohort and the control cohort comprised 775 and 716 pregnant patients, respectively. The overall incidence of pregnancy was significantly lower in the I-131 cohort (adjusted HR = 0.77, 95% CI = 0.70–0.86) and it was also observed when the patients were stratified according to age (HR = 0.73, 95% CI = 0.64–0.83 in 25–34 years; HR = 0.63, 95% CI = 0.49–0.82 in 35–44 years). Patients in the I-131 cohort had a lower successful delivery rate, particularly among patients in 25 to 34 years (OR = 0.60, 95% CI = 0.45–0.80). No significant difference was observed for adverse pregnancy conditions between 2 cohorts. I-131 therapy is associated with decreased pregnancy and successful delivery rates. The underlying mechanism likely involves physician recommendation, patient's psychological issue, and potential impact of I-131 treatment on reproductive health. Further investigation is needed.

Objective To assess the safety and health effects of vitamin D supplementation during pregnancy. Methods and Design Datasets from two randomized clinical trials were first analyzed separately then combined for this analysis using a common data dictionary. In the NICHD trial, women were randomized to 400, 2000, or 4000 IU vitamin D3/day, stratified by race. In the Thrasher Research Fund trial, participants were randomized to 2000 or 4000 IU vitamin D3/day. Study drugs were from the same manufacturing lot for both trials. Identical questionnaires were given for comparable sociodemographics & clinical characteristics. Outcome measures were: (1) maternal and neonatal 25(OH)D achieved, and (2) maternal comorbidities of pregnancy (COP). SAS 9.3 was used for all analyses. Results In the combined cohort, there were 110 controls, 201 in the 2000 IU group, and 193 in the 4000 IU group. No differences between groups in baseline 25(OH)D were found; however, delivery and cord blood values were greater in the 4000 IU group (p<0.0001), an effect that persisted even after controlling for race and study. A greater percent were vitamin D replete in the 4000 IU group (p<0.0001). There was a trend where the 4000 IU group had decreased rates of comorbidities of pregnancy. There was a strong association between COP and final maternal 25(OH)D; an effect that persisted even after controlling for race and study (p=0.006). Conclusions Supplementation with 4000 IU/day was associated with lower risk of hypovitaminosis D than Control and 2000 IU groups. While not statistically significant, there was a trend toward lower rates of COP as supplementation dose increased. Maternal delivery 25(OH)D was inversely associated with any comorbidity of pregnancy, with fewer events as 25(OH)D increased. Future studies are needed to confirm these findings and determine the mechanisms of action of such effects. PMID:23314242

Chlorination by-products (CBPs) in drinking water have been associated with an increased risk of adverse pregnancy outcomes, including small for gestational age at term (term-SGA) and preterm delivery. Epidemiological evidence is weakened by a generally inaccurate exposure assessment, often at an ecological level. A case control study with incident cases was performed in nine Italian towns between October 1999 and September 2000. A total of 1,194 subjects were enrolled: 343 preterm births (26th-37th not completed week of pregnancy), 239 term-SGA (from 37th completed week, and weight less than the lowest 10th percentile) and 612 controls. Exposure was assessed both by applying a questionnaire on mothers' personal habits during pregnancy and by water sampling directly at mothers' homes. Levels of trihalomethanes (THMs) were low (median: 1.10 microg l(-1)), while chlorite and chlorate concentrations were relatively high (median: 216.5 microg l(-1) for chlorites and 76.5 microg l(-1) for chlorates). Preterm birth showed no association with CBPs, while term-SGA, when chlorite levels > or =200 microg l(-1) combined with low and high levels of inhalation exposure are considered, suggested a dose-response relationship (adjusted-Odds Ratios (ORs): 1.52, 95%CI: 0.91-2.54 and 1.70, 95%CI: 0.97-3.0, respectively). A weak association with high exposure levels of either THMs (> or =30 microg l(-1)), or chlorite or chlorate (> or =200 microg l(-1)) was also found (adjusted-OR: 1.38, 95%CI: 0.92-2.07). Chlorine dioxide treatment is widespread in Italy; therefore, chlorite levels should be regularly and carefully monitored and their potential effects on pregnancy further evaluated and better understood.

The porphyrias comprise a heterogeneous group of rare, primarily hereditary, metabolic diseases caused by a partial deficiency in one of the eight enzymes involved in the heme biosynthesis. Our aim was to assess whether acute or cutaneous porphyria has been associated with excess risks of adverse pregnancy outcomes. A population-based cohort study was designed by record linkage between the Norwegian Porphyria Register, covering 70% of all known porphyria patients in Norway, and the Medical Birth Registry of Norway, based on all births in Norway during 1967-2006. The risks of the adverse pregnancy outcomes preeclampsia, delivery by caesarean section, low birth weight, premature delivery, small for gestational age (SGA), perinatal death, and congenital malformations were compared between porphyric mothers and the rest of the population. The 200 mothers with porphyria had 398 singletons during the study period, whereas the 1,100,391 mothers without porphyria had 2,275,317 singletons. First-time mothers with active acute porphyria had an excess risk of perinatal death [adjusted odds ratio (OR) 4.9, 95% confidence interval (CI) 1.5-16.0], as did mothers with the hereditable form of porphyria cutanea tarda (PCT) (3.0, 1.2-7.7). Sporadic PCT was associated with an excess risk of SGA [adjusted relative risk (RR) 2.0, 1.2-3.4], and for first-time mothers, low birth weight (adjusted OR 3.4, 1.2-10.0) and premature delivery (3.5, 1.2-10.5) in addition. The findings suggest women with porphyria should be monitored closely during pregnancy.

Background Adalimumab has been used in patients with moderately to severely active rheumatoid arthritis (RA) for over 10 years and has a well-established safety profile across multiple indications. Objective To update adverse events (AEs) of special interest from global adalimumab clinical trials in patients with RA. Methods This analysis includes 15 132 patients exposed to adalimumab in global RA clinical trials. AEs of interest included overall infections, laboratory abnormalities and AEs associated with influenza vaccination. Pregnancy outcome data were collected from the Adalimumab Pregnancy Registry. Results Serious infections and tuberculosis occurred at a rate of 4.7 and 0.3 events/100 patient-years, respectively. Two patients experienced hepatitis B reactivation. No significant laboratory abnormalities were reported with adalimumab-plus-methotrexate compared with placebo-plus-methotrexate. Influenza-related AEs occurred in 5% of vaccinated patients compared with 14% of patients not vaccinated during the study. Relative risk of major birth defects and spontaneous abortions in adalimumab-exposed women were similar between that of unexposed women with RA and healthy women. Conclusions This analysis confirms and expands the known safety profile of adalimumab and reports no additional safety risk of laboratory abnormalities, hepatitis B reactivation and pregnancy outcomes, including spontaneous abortions and birth defects. The benefits of influenza vaccination are reinforced.

We analyzed the effects of 2-g centrifugation on estrous cycling, mating success and pregnancy outcome in rats. Sexually mature female and male rats were assigned to either 2-g centrifuge or non-centrifuge conditions, and to non-breeding or breeding conditions. In non-breeding females, estrous cycles were analyzed by examining vaginal cytology before and for 35 days during centrifugation. Breeding females were time-mated following 7 days of adaptation to centrifugation. Following adaptation to centrifugation, estrous cycle duration over a five-cycle period was similar in centrifuged and non-centrifuged females. Identical numbers of centrifuged and non-centrifuged females conceived, however centrifuged females took four-times longer than controls to achieve conception. Births occurred at the normal gestational length. Pup birth weight and postnatal survival were p<0.05 reduced in centrifuged as compared to non-centrifuged groups. In conclusion, 2-g centrifugation had no effect on estrous cycle length or the probably of becoming pregnant but delayed conception and diminished pregnancy outcome.

Objectives. This study aims to evaluate perinatal outcomes such as gestational age at delivery and live birth rate in singleton and twin gestation with or without fetal reduction. Method. A retrospective analysis was done on patients which were divided into reduced and unreduced groups on the basis of order of reduction of one or more fetuses between 6 and 13 weeks of gestation. Patients records were studied to note gestational age at delivery/abortion, birth weight, and neonatal outcome. Result. The cohort included a total of 292 patients: 102 singletons and 190 twins. 52 pregnancies were reduced in singleton cohort and 68 were reduced in twin cohort. No statistical difference was observed in live birth rate, gestational age at delivery, and birth weight and significant higher incidence of IUGR was observed in reduced and unreduced twin gestation. In singleton pregnancies however preterm delivery rate increased with fetal reduction. Conclusion. Although reduction does not reduce the live birth rate, it does reduce gestation age of delivery and birth weight of newborn. This effect is more apparent when multiple gestation is reduced to singleton. PMID:27999824

Teenage pregnancy is a worldwide problem bearing serious social and medical implications relating to maternal and child health. A cross-sectional observational study was undertaken to compare the different sociodemographic characteristics and perinatal outcomes of teenage primigravida mothers with those of adult primigravida mothers in a tertiary-care hospital in eastern India. A sample of 350 each in cases and comparison group comprised the study subjects. Data were collected through interviews and by observations using a pretested and predesigned schedule. Results revealed that the teenage mothers had a higher proportion (27.7%) of preterm deliveries compared to 13.1% in the adult mothers and had low-birthweight babies (38.9% vs 30.4% respectively). Stillbirth rate was also significantly higher in teenage deliveries (5.1% vs 0.9% respectively). The teenage mothers developed more adverse perinatal complications, such as preterm births, stillbirths, neonatal deaths, and delivered low-birthweight babies, when compared with those of the adult primigravida mothers. Teenage pregnancy is still a rampant and important public-health problem in India with unfavourable perinatal outcomes and needs to be tackled on a priority basis.

This retrospective review of hospital records analysed pregnancy outcome with 2 different treatments for women with recurrent miscarriage diagnosed with antiphospholipid syndrome in the index pregnancy. Of 64 women, 29 had received aspirin and 35 aspirin plus heparin. Pregnancy-induced hypertension, prematurity, intrauterine growth restriction and neonatal death were considered as maternal and fetal complications. There were no significant differences in antenatal and maternal complications between the groups. HOwever, there were significant differences in mean anticardiolipin IgG antibody levels. Aspirin alone or in combination with parin was equally efficacious in women with antiphospholipid syndrome and recurrent miscarriage.

It has become clear in recent years that the human intestinal microbiota plays an important role in maintaining health and thus is an attractive target for clinical interventions. Scientists and clinicians have become increasingly interested in assessing the ability of probiotics and prebiotics to enhance the nutritional status of malnourished children, pregnant women, the elderly, and individuals with non-communicable disease-associated malnutrition. A workshop was held by the International Scientific Association for Probiotics and Prebiotics (ISAPP), drawing on the knowledge of experts from industry, medicine, and academia, with the objective to assess the status of our understanding of the link between the microbiome and under-nutrition, specifically in relation to probiotic and prebiotic treatments for under-nourished individuals. These discussions led to four recommendations: (1) The categories of malnourished individuals need to be differentiated To improve treatment outcomes, subjects should first be categorized based on the cause of malnutrition, additional health-concerns, differences in the gut microbiota, and sociological considerations. (2) Define a baseline “healthy” gut microbiota for each category Altered nutrient requirement (for example, in pregnancy and old age) and individual variation may change what constitutes a healthy gut microbiota for the individual. (3) Perform studies using model systems to test the effectiveness of potential probiotics and prebiotics against these specific categories These should illustrate how certain microbiota profiles can be altered, as members of different categories may respond differently to the same treatment. (4) Perform robust well-designed human studies with probiotics and/or prebiotics, with appropriate, defined primary outcomes and sample size These are critical to show efficacy and understand responder and non-responder outcomes. It is hoped that these recommendations will lead to new approaches

Context: Inflammatory mediators are associated with type 2 and gestational diabetes. It is unknown whether there are associations with glucose in pregnant women with lesser degrees of hyperglycemia. Objective: The objective of the study was to examine associations of inflammatory mediators with maternal glucose levels and neonatal size in a subset of participants in the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study. Design: Eligible pregnant women underwent a 75-g oral glucose tolerance test between 24 and 32 wk gestation, and levels of C-peptide, adiponectin, plasminogen activator inhibitor type 1 (PAI-1), C-reactive protein (CRP), and resistin were measured in fasting serum samples. Associations of inflammatory mediators with maternal glucose and with birth size were assessed using multiple linear regression analyses, adjusting for maternal body mass index (BMI), fasting C-peptide, and other potential confounders. Results: Mean levels of adiponectin declined, and PAI-1 and CRP increased across increasing levels of maternal glucose, BMI, and C-peptide. For example, for fasting plasma glucose less than 75 mg/dl and fasting plasma glucose of 90 mg/dl or greater, adiponectin was 22.5 and 17.4 μg/ml and PAI-1 was 30.9 and 34.2 ng/ml, respectively. Associations with 1- and 2-h plasma glucose remained significant for adiponectin (P < 0.001), PAI-1 (P < 0.05), and CRP (P < 0.01) after adjustment for BMI and C-peptide. Adiponectin and CRP were inversely associated with birth weight, sum of skinfolds and percent body fat, and PAI-1 with sum of skinfolds (all P < 0.05) after adjustment for confounders. Resistin was not associated with 1- or 2-h glucose or birth size. Conclusion: Levels of inflammatory mediators are associated with levels of maternal glucose in pregnant women without overt diabetes.

Introduction: Besides the typical complaints and symptoms, myomas can cause sterility, infertility and complications during pregnancy. Laparoscopic interventions reach their limits with regard to organ preservation and the simultaneous desire to have children in the removal of multiple and larger intramural myoma nodes. The aim of this study is to examine fertility status and pregnancy outcome after myoma removal by minilaparotomy (skin incision maximal 8 cm) in women with pronounced uterus myomatosus. Materials and Methods: This retrospective study makes use of the data from 160 patients with an average age of 34.6 years. Factors analysed include number, size and localisation of the myomas, complaints due to the myoma, pre- and postoperative gravidity, mode of delivery, and complications of birth. Results: Indications for organ-sparing myoma enucleation were the desire to have children (72.5 %), bleeding disorders (60 %) and pressure discomfort (36.5 %). On average 4.95 (SD ± 0.41), maximally 46 myomas were removed. The largest myoma had a diameter of 6.64 cm (SD ± 2.74). 82.5 % of the patients had transmural myomas, in 17.5 % the uterine cavity was inadvertently opened. On average the operating time was 163 minutes (SD ± 45.47), the blood loss 1.59 g/dL (SD ± 0.955). 60.3 % of the patients with the desire to have children became pregnant postoperatively. 75.3 % of the pregnancies were on average carried through to the 38th week (28.4 % vaginal deliveries, 71.6 % Caesarean sections). In the postoperative period there was one case of uterine rupture in the vicinity of a previous scar. Discussion: By means of the microsurgical "mini-laparotomy" even extensive myomatous uterine changes can, in the majority of cases, be operated in an organ-sparing manner with retention of the ability to conceive and to carry a pregnancy through to maturity of the infant. The risk for a postoperative uterine rupture in a subsequent pregnancy and

3,4-methylenedioxymethamphetamine (MDMA) or "Ecstasy" is one of the most widely used illicit recreational drugs among young adults. MDMA is an indirect monoaminergic agonist and reuptake inhibitor that primarily affects the serotonin system. Preclinical studies in animals have found prenatal exposure related to neonatal tremors and long-term learning and memory impairments. To date, there are no prospective studies of the sequelae of prenatal exposure to MDMA in humans, despite concerns about its potential for harmful effects to the fetus. The present study is the first to prospectively identify MDMA-using women during pregnancy and to document patterns and correlates of use with neonatal and early infancy outcomes of offspring. All mothers and infants were prospectively recruited through the Case Western Reserve University (CWRU) and University of East London (UEL) Drugs and Infancy Study (DAISY) that focused on recreational drug use in pregnant women. Women were interviewed about substance use prior to and during pregnancy and infants were seen at 1 and 4 months using standardized, normative assessments of neonatal behavior, and cognitive and motor development, including the NICU Network Neurobehavioral Scale (NNNS), the Bayley Mental and Motor Development Scales (MDI, PDI), and the Alberta Infant Motor Scales (AIMS). The sample was primarily middle class with some university education and in stable partner relationships. The majority of women recruited had taken a number of illicit drugs prior to or during pregnancy. Group differences between those polydrug using women who had specifically used MDMA during pregnancy (n=28) and those who had not (n=68) were assessed using chi-square and t-tests. MDMA and other drug effects were assessed through multiple regression analyses controlling for confounding variables. Women who used MDMA during pregnancy had fewer prior births and more negative sequelae associated with their drug use, including more health, work, and
Background Most of Multiple Sclerosis (MS) patients undergo disease modifying drug (DMD) therapy at childbearing age. The objective of this prospective, collaborative study, was to assess outcomes of pregnancies fathered by MS patients undergoing DMD. Methods Structured interviews on pregnancies fathered by MS patients gathered in the Italian Pregnancy Dataset were collected; pregnancies were divided according to father exposure or unexposure to DMD at time of procreation. Treatment were compared with multivariable logistic and linear models. Results Seventy-eight pregnancies fathered by MS patients were tracked. Forty-five patients were taking DMD at time of conception (39 beta-interferons, 6 glatiramer acetate), while 33 pregnancies were unexposed to DMD. Seventy-five pregnancies ended in live-births, 44 in the exposed and 31 in the unexposed group. No significant differences between the two groups were found in the risk of spontaneous abortion or malformations (p > 0.454), mean gestational age (p = 0.513), frequency of cesarean delivery (p = 0.644), birth weight (p = 0.821) and birth length (p = 0.649). In comparison with data of the Italian general population, the proportion of spontaneous abortion and caesarean delivery in exposed pregnancies fell within the estimates, while the proportion of pre-term delivery in the exposed group was higher than expected. Conclusions Our data indicate no association between paternal DMD exposure at time of conception and risk of spontaneous abortion, adverse fetal outcomes and congenital malformations. Further studies clarifying the role of DMD fathers intake prior and during pregnancy are desirable, to supply guidelines for clinical practice. PMID:24884599

Background Poor nutrition may be associated with mother-to-child transmission (MTCT) of HIV and other adverse pregnancy outcomes. Objective The objective was to examine the relation of nutritional indicators with adverse pregnancy outcomes among HIV-infected women in Tanzania, Zambia, and Malawi. Design Body mass index (BMI; in kg/m2) and hemoglobin concentrations at enrollment and weight change during pregnancy were prospectively related to fetal loss, neonatal death, low birth weight, preterm birth, and MTCT of HIV. Results In a multivariate analysis, having a BMI < 21.8 was significantly associated with preterm birth [odds ratio (OR): 1.82; 95% CI: 1.34, 2.46] and low birth weight (OR: 2.09; 95% CI: 1.41, 3.08). A U-shaped relation between weight change during pregnancy and preterm birth was observed. Severe anemia was significantly associated with fetal loss or stillbirth (OR: 3.67; 95% CI: 1.16, 11.66), preterm birth (OR: 2.08; 95% CI: 1.39, 3.10), low birth weight (OR: 1.76; 95% CI: 1.07, 2.90), and MTCT of HIV by the time of birth (OR: 2.26; 95% CI: 1.18, 4.34) and by 4−6 wk among those negative at birth (OR: 2.33; 95% CI: 1.15, 4.73). Conclusions Anemia, poor weight gain during pregnancy, and low BMI in HIV-infected pregnant women are associated with increased risks of adverse infant outcomes and MTCT of HIV. Interventions that reduce the risk of wasting or anemia during pregnancy should be evaluated to determine their possible effect on the incidence of adverse pregnancy outcomes and MTCT of HIV.

As a follow-up of our study of pregnant women, we report effects of zinc supplementation during pregnancy in another population of 138 Hispanic teenagers in Los Angeles. Teenagers were randomized (double-blind) to a control or zinc-supplemented group and received similar daily vitamin and mineral supplements except for 20 mg zinc added to the zinc-supplemented group's capsules. Initially, mean dietary zinc intakes of both groups were about 50% of the Recommended Dietary Allowance and their mean serum zinc levels did not differ significantly (69.8 +/- 11.2 micrograms/dl in control and 69.0 +/- 11.4 micrograms/dl in zinc-supplemented group). Zinc supplementation did not maintain mean serum zinc levels during pregnancy but, as in our earlier study, it reduced (p = 0.018) the number of low serum zinc values (less than or equal to 53 micrograms/dl) in late pregnancy. Zinc supplementation did not affect outcome of pregnancy but serum zinc levels were lower (p = 0.038) in teenagers with pregnancy-induced hypertension than in normotensives.

Maternal infection in pregnancy is a known risk factor for adverse pregnancy outcome, and a number of zoonotic pathogens may constitute a risk to pregnant women and their fetuses. With animal contact as a proxy for the risk of zoonotic infection, this study aimed to evaluate pregnancy outcome in women with self-reported occupational or domestic contact with livestock compared to pregnant women without such contact. The Danish National Birth Cohort collected information on pregnancy outcome from 100 418 pregnant women (1996-2002) from which three study populations with occupational and/or domestic exposure to livestock and a reference group of women with no animal contact was sampled. Outcome measures were miscarriage, very preterm birth (before gestational week 32), preterm birth (before 37 gestational weeks), small for gestational age (SGA), and perinatal death. Adverse reproductive outcomes were assessed in four different exposure groups of women with occupational or domestic exposure to livestock with no association found between exposure to livestock and miscarriage, preterm birth, SGA or perinatal death. These findings should diminish general occupational health concerns for pregnant women with exposures to a range of different farm animals.

Maternal preconception diet is proposed to affect fertility. Prior research assessing the effect of altering the fatty acid profile on female fertility is conflicting. The aim of this study was to assess the effect of preconception maternal diet, specifically fatty acid profile, on pregnancies and live births following in vitro fertilisation (IVF). Forty-six overweight and obese women undergoing IVF were randomised to a diet and physical activity intervention (intervention) or standard care (control). Outcome measures included pregnancy, live birth and pre-study dietary intake from food frequency questionnaire. Twenty pregnancies (n = 12/18 vs. n = 8/20, p = 0.12) and 12 live births (n = 7/18 vs. n = 5/20, p = 0.48) occurred following the intervention with no differences between the treatment groups. On analysis adjusted for BMI and smoking status, women who became pregnant had higher levels of polyunsaturated fatty acid (PUFA) intake (p = 0.03), specifically omega-6 PUFA and linoleic acid (LA) (p = 0.045) with a trend for an elevated intake of omega-3 PUFA (p = 0.06). There were no dietary differences for women who did or did not have a live birth. Maternal preconception PUFA, and specifically omega-6 and LA intake, are associated with improved pregnancy rates in overweight and obese women undergoing IVF. This has implications for optimising fertility through preconception nutrition.
Background The nutritional status of the mother prior to and during pregnancy plays a vital role in fetal growth and development, and maternal undernourishment may lead to adverse perinatal outcomes including intrauterine growth restriction (IUGR). Several macronutrient interventions had been proposed for adequate protein and energy supplementation during pregnancy. The objective of this paper was to review the effect of balanced protein energy supplementation during pregnancy on birth outcomes. This paper is a part of a series of reviews undertaken for getting estimates of effectiveness of an intervention for input to Lives Saved Tool (LiST) model. Methods A literature search was conducted on PubMed, Cochrane Library and WHO regional data bases to identify randomized trials (RCTs) and quasi RCTs that evaluated the impact of balanced protein energy supplementation in pregnancy. Balanced protein energy supplementation was defined as nutritional supplementation during pregnancy in which proteins provided less than 25% of the total energy content. Those studies were excluded in which the main intervention was dietary advice to pregnant women for increase in protein energy intake, high protein supplementation (i.e. supplementation in which protein provides at least 25% of total energy content), isocaloric protein supplementation (where protein replaces an equal quantity of non-protein energy content), or low energy diet to pregnant women who are either overweight or who exhibit high weight gain earlier in gestation. The primary outcomes were incidence of small for gestational age (SGA) birth, mean birth weight and neonatal mortality. Quality of evidence was evaluated according to the Child Health Epidemiology Reference group (CHERG) adaptation of Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Results The final number of studies included in our review was eleven comprising of both RCTs and quasi-RCTs. Our meta-analysis indicates that

Excessive response to ovarian stimulation is common among hyper-responder patients undergoing assisted reproductive technology (ART). Cycle cancellations and severe ovarian hyperstimulation syndrome (OHSS) are all detrimental consequences observed within this cohort and several approaches have been proposed to enhance outcomes. The current study is designed to evaluate whether laparoscopic ovarian diathermy (LOD) improves ART outcomes and pregnancy rates by reducing Anti-mullerian hormone (AMH) levels in a group of patients who had a history of recurrent ART failure and high response. A total of 40 hyper-responder patients with history of previous ART failure were included. Group I consisted of 22 patients that underwent LOD prior to ART. Group II consisted of 18 patients that underwent only ART. Cycle outcomes of groups were compared. Following LOD, significant reduction in AMH levels were detected in group I (4.75 ng/mL to 2.25 ng/mL). Clinical pregnancies were similar among groups (40% versus 27.8% p = 0.65). There was no cycle cancellation in Group I, whereas there were three cycle cancellations observed due to OHSS in Group II. Our results indicate that LOD might offer enhanced fertility outcomes and may reduce the likelihood of cycle cancellations in hyper-responders with previous ART failures.

Innovative use of standardized patients (SPs) in a telemedicine environment can improve learning outcomes and clinical competencies. This randomized, cross-over study examined the relationship of technology-based strategies and the improvement of knowledge outcomes and competencies. Results showed that the innovative use of SPs and telemedicine, compared to a traditional distance learning teaching methodology, significantly improved learning outcomes. In addition, there was a significant increase in performance motivation and an interesting decrease in student satisfaction that may be linked to the pressure of performance-based learning. This article addresses knowledge improvement only.

Vitamin D has garnered a great deal of attention in recent years due to a global prevalence of vitamin D deficiency associated with an increased risk of a variety of human diseases. Specifically, hypovitaminosis D in pregnant women is highly common and has important implications for the mother and lifelong health of the child, since it has been linked to maternal and child infections, small-for-gestational age, preterm delivery, preeclampsia, gestational diabetes, as well as imprinting on the infant for life chronic diseases. Therefore, factors that regulate vitamin D metabolism are of main importance, especially during pregnancy. The hormonal form and most active metabolite of vitamin D is calcitriol. This hormone mediates its biological effects through a specific nuclear receptor, which is found in many tissues including the placenta. Calcitriol synthesis and degradation depend on the expression and activity of CYP27B1 and CYP24A1 cytochromes, respectively, for which regulation is tissue specific. Among the factors that modify these cytochromes expression and/or activity are calcitriol itself, parathyroid hormone, fibroblast growth factor 23, cytokines, calcium and phosphate. This review provides a current overview on the regulation of vitamin D metabolism, focusing on vitamin D deficiency during gestation and its impact on pregnancy outcomes. PMID:25584965

The agricultural industry has some of the highest incidence rates and numbers of occupational injuries and illnesses in the United States. Injuries and illnesses in agriculture result from accidents, falls, excessive heat, repetitive motion and adverse pesticide exposure. Women working in agriculture are exposed to the same hazards and risks as their male counterparts, but can face additional adverse impacts on their reproductive health. Yet, few occupational risk assessment studies have considered the reproductive health of female farmworkers. The objective of this community-based participatory research study was to conduct a retrospective, cross-sectional survey to collect information on workplace conditions and behaviors and maternal, pregnancy and infant health outcomes among a sample of female nursery and fernery farmworkers in Central Florida. Survey results showed that nursery workers were more likely to report health symptoms during their pregnancy than fernery workers. We also observed a self-reported increased risk of respiratory illness in the first year of life for infants whose mothers worked in ferneries. Our findings confirm that agricultural work presents potential reproductive hazards for women of childbearing age. PMID:25101767

Recent research in environmental epidemiology has attempted to estimate the effects of exposure to nature, often operationalized as vegetation, on health. Although many analyses have focused on vegetation or greenness with regard to physical activity and weight status, an incipient area of interest concerns maternal health and birth outcomes. This paper reviews 14 studies that examined the association between greenness and maternal or infant health. Most studies were cross-sectional and conducted in birth cohorts. Several studies found evidence for positive associations between greenness and birth weight and maternal peripartum depression. Few studies found evidence for an association between greenness and gestational age or other birth outcomes, or between greenness and preeclampsia or gestational diabetes. Several assessed effect modification by individual or area-level socioeconomic status and found that effects were stronger among those of lower socioeconomic status. Few studies conducted mediation analyses of any kind. Future research should include more diverse birth outcomes and focus on maternal health (especially mental health) and capitalize on richer exposure information during pregnancy rather than cross-sectional assessment at birth.

To examine risks for adverse perinatal outcomes among Southeast Asian women with pregnancies complicated by gestational diabetes mellitus (GDM) or preeclampsia. Perinatal outcomes of singleton births of Cambodian (3,489), Laotian (2,038), Vietnamese (11,605), Japanese (3,083) and non-Hispanic White women (33,088) were analyzed using Washington state linked birth certificate and hospitalization discharge records (1993-2006). Both Cambodian (aOR = 1.68) and Laotian (aOR = 1.71) women with GDM had increased odds of macrosomia when compared with Japanese women with GDM. Southeast Asian women with GDM had reduced odds of macrosomia when compared with White women. Southeast Asian women with preeclampsia had increased odds for preterm delivery when compared with Japanese and White women with preeclampsia. Research is needed to understand why Southeast Asian women with GDM are more likely to have better perinatal outcomes when compared with White women. Vigilant monitoring and culturally sensitive care for Southeast Asian women with preeclampsia is needed.

Objective To evaluate the evidence on the efficacy of psychosocial interventions for improving pregnancy rates and reducing distress for couples in treatment with assisted reproductive technology (ART). Design Systematic review and meta-analysis. Data sources PsycINFO, PubMed, EMBASE, CINAHL, Web of Science and The Cochrane Library between 1978 and April 2014. Study selection Studies were considered eligible if they evaluated the effect of any psychosocial intervention on clinical pregnancy and/or distress in infertile participants, used a quantitative approach and were published in English. Data extraction Study characteristics and results were extracted and the methodological quality was assessed. Effect sizes (ES; Hedges g) were pooled using a random effects model. Heterogeneity was assessed using the Q statistic and I2, and publication bias was evaluated using Egger’s method. Possible moderators and mediators were explored with meta-analyses of variances (ANOVAs) and meta-regression. Results We identified 39 eligible studies (total N=2746 men and women) assessing the effects of psychological treatment on pregnancy rates and/or adverse psychological outcomes, including depressive symptoms, anxiety, infertility stress and marital function. Statistically significant and robust overall effects of psychosocial intervention were found for both clinical pregnancy (risk ratio=2.01; CI 1.48 to 2.73; p<0.001) and combined psychological outcomes (Hedges g=0.59; CI 0.38 to 0.80; p=0.001). The pooled ES for psychological outcomes were generally larger for women (g: 0.51 to 0.73) than men (0.13 to 0.34), but the difference only reached statistical significance for depressive symptoms (p=0.004). Meta-regression indicated that larger reductions in anxiety were associated with greater improvement in pregnancy rates (Slope 0.19; p=0.004). No clear-cut differences were found between effects of cognitive–behavioural therapy (CBT; g=0.84), mind–body interventions (0.61) and

This retrospective cohort study was conducted at Newham University Hospital, London to investigate maternal outcome of planned vaginal delivery as well as rate of maternal-to-child transmission. Between June 2004 and June 2006, 23 (16%) women of 144 HIV-infected pregnant women opted for planned vaginal delivery. Offer of vaginal delivery was based on maternal HIV RNA count <50 cells/ml around 36 weeks' gestation. All women received antiretroviral therapy. Fifteen (65%) women achieved vaginal delivery. Babies were followed up over 18 months. All babies had antiretroviral prophylaxis. No babies were breast-fed. There was no report of maternal-to-child transmission in any of these babies. Our study suggests that planned vaginal delivery could be safe with antiretroviral therapy in pregnancy, optimal intrapartum care, viral load of <1000 copies/ml at delivery, retroviral prophylaxis for babies and avoidance of breast-feeding.

Antiepileptic drugs (AEDs) are prescribed commonly to women of childbearing age. In utero exposure to some AEDs can have significant cognitive and behavioral consequences for the unborn child. Recently, prospective studies of women taking AEDs during pregnancy have added significantly to our understanding of cognitive and behavioral teratogenic risks posed by fetal AED exposure. Valproate is clearly associated with impaired cognitive development as well as an increased risk of disorders such as autism and autism spectrum disorder. Exposure to carbamazepine, lamotrigine, levetiracetam, or phenytoin monotherapy is associated with more favorable cognitive and behavioral outcomes than valproate, but more data are required to clarify if these AEDs have more subtle effects on cognition and behavior. There are insufficient data on the developmental effects of other AEDs in humans. Further, the underlying mechanisms of cognitive teratogenesis are poorly understood, including the genetic factors that affect susceptibility to AEDs.

Lipomeningomyocele is one of the types of occult spinal dysraphism associated with tethered cord syndrome, which is characterised by neurodeficit symptomatology due to stretch- induced functional disorder of the spinal cord with its caudal part attached by an in elastic tissue. There is stretching of conus medullaris and nerve roots due to disproportionate growth between vertebral column and spinal cord, resulting in various neurological deficits. Its incidence is approximately 1 in 4000 births in the USA, with a slightly higher female preponderance, although its true incidence is not known. There are very few studies on pregnancy outcome in these patients and the management dilemma in this group has prompted us to report this case. PMID:27790529

A retrospective cohort study was conducted to compare pregnancy outcomes in farming households that used pesticides conventionally with those that practiced integrated pest management (IPM) in Nueva Ecija, Philippines, in the period 1998-1999. Conventional pesticide users (CPUs) were defined as pesticide appliers who used pesticides routinely and regularly, whereas users of IPM were those who used pesticides as necessary, and on economically injured crop areas only. The data sets were subjected to the chi-square test of association, Fisher's exact probability test, and logistic regression analysis. At a significance level at 0.05, spontaneous abortion occurred significantly more often among the 345 CPU households than among the 331 IPM households (adjusted risk ratio 6.17). Likewise, birth defects were significantly more common in the CPU group (adjusted risk ratio 4.56). Thus, people of reproductive age who plan to have children should avoid any use of pesticides.

Objectives Preterm birth (PTB) and small for gestational age (SGA) are major causes of perinatal mortality and morbidity. Previous studies indicated a range of risk factors associated with these poor outcomes, including maternal psychosocial and economic wellbeing. This paper will explore a range of psycho-social and economic factors in an ethnically diverse population. Methods The UK's Born in Bradford cohort study recruited pregnant women attending a routine antenatal appointment at 26-28 weeks' gestation at the Bradford Royal Infirmary (2007-2010). This analysis includes 9680 women with singleton live births who completed the baseline questionnaire. Data regarding maternal socio-demographic and mental health were recorded. Outcome data were collected prospectively, and analysed using multivariate regression models. The primary outcomes measured were: PTB (<37 weeks' gestation) and SGA (<10th customised centile). Results After adjustment for socio-demographic and medical factors, financial strain was associated with a 45 % increase in PTB (OR 1.45: 95 % CI 1.06-1.98). Contrary to expectation, maternal distress in Pakistani women was negatively associated with SGA (OR 0.65: CI 0.48-0.88). Obesity in White British women was protective for PTB (OR 0.67: CI 0.45-0.98). Previously recognized risk factors, such as smoking in pregnancy and hypertension, were confirmed. Conclusions This study confirms known risk factors for PTB and SGA, along with a new variable of interest, financial strain. It also reveals a difference in the risk factors between ethnicities. In order to develop appropriate targeted preventative strategies to improve perinatal outcome in disadvantaged groups, a greater understanding of ethno-specific risk factors is required.

Background. Influenza and Tdap vaccines are vital factors for improving maternal and neonatal health outcomes. Methods. A prospective, longitudinal study was conducted to determine whether the American College of Obstetricians and Gynecologists' (ACOG's) efforts to increase ob-gyn use of their immunization toolkits and vaccination administration were successful. Pre- and postintervention questionnaires were mailed to a random sample of 1,500 ACOG members between August 2012 and July 2015. Results. Significantly more postintervention survey ob-gyns reported that they received the immunization toolkits than preintervention survey ob-gyns (84.5% versus 67.0%, p < .001). The large majority of ob-gyns from both surveys (76.9% versus 78.9%) reported that they offered or planned to offer influenza vaccinations to their patients for the 2012-2013 and 2014-2015 flu seasons. Postintervention survey respondents were significantly more likely than preintervention survey participants to report that they routinely offer Tdap vaccinations to all patients during pregnancy (76.8% versus 59.3%, p < .001). Conclusion. ACOG's efforts to improve ob-gyn use of immunization toolkits and vaccine administration appear to have been successful in several ways. ACOG's toolkits are an example of an effective intervention to overcome barriers to offering vaccines and help improve influenza and Tdap immunization coverage for pregnant women. PMID:26924918

Systemic lupus erythematosus (SLE) can affect the menstruation, fertility, and pregnancy outcomes of the affected subjects. There is very little data on this aspect of the disease in Indian patients. Our aim was to study the menstrual, fertility, and pregnancy outcomes in these patients in comparison with patients of rheumatoid arthritis (RA) and also to study the effect of cyclophosphamide therapy on menstrual cycles in patients with SLE. Four hundred and twenty patients of SLE (210) and RA (210) were interviewed using a standard questionnaire and available medical records used. After disease-onset, the chances of adverse pregnancy outcomes were significantly more in patients with SLE compared to RA [OR = 5.17 (2.13-12.52); p ≤ 0.001]. Compared to the National average in India, the average number of living children is lesser in patients with RA (2.39 ± 1.39, p = 0.002), but more so in patients with SLE (1.44 ± 1.35, p = 0.001). A younger age at diagnosis and cyclophosphamide therapy was found to be independently associated with menstrual irregularities after disease-onset. We conclude that pregnancy outcome in patients with SLE in India is worse in comparison to patients with RA. Average family size of patients with SLE and RA is less when compared to National average in India. Patients with SLE are more prone for menstrual irregularities, especially those who receive cyclophosphamide treatment.

The relationships between meteorology and pregnancy outcomes are not well known. This article reviews available evidence on the relationships between seasonality or meteorology and three major pregnancy outcomes: the hypertensive disorders of pregnancy (including preeclampsia, eclampsia and gestational hypertension), gestational length and birth weight. In total 35, 28 and 27 studies were identified for each of these outcomes. The risks of preeclampsia appear higher for women with conception during the warmest months, and delivery in the coldest months of the year. Delivery in the coldest months is also associated with a higher eclampsia risk. Patterns of decreased gestational lengths have been observed for births in winter, as well as summer months. Most analytical studies also report decreases in gestational lengths associated with heat. Birth weights are lower for deliveries occurring in winter and in summer months. Only a limited number of studies have investigated the effects of barometric pressure on gestational length or the effects of temperature and sunshine exposure on birth weight, but these questions appear worth investigating further. Available results should encourage further etiological research aiming at enhancing our understanding of the relationships between meteorology and adverse pregnancy outcomes, ideally via harmonized multicentric studies.

To identify Psychopathology, Psychosocial problems and substance use (PPS) as predictors of adverse pregnancy outcomes, two screen-and-advice instruments were developed: Mind2Care (M2C, self-report) and Rotterdam Reproductive Risk Reduction (R4U, professional's checklist). To decide on the best clinical approach of these risks, the performance of both instruments was compared. Observational study of 164 pregnant women who booked at two midwifery practices in Rotterdam. Women were consecutively screened with M2C and R4U. For referral to tailored care based on specific PPS risks, inter-test agreement of single risks was performed in terms of overall accuracy and positive accuracy (risk present according to both instruments). With univariate regression analysis we explored determinants of poor agreement (<90 %). For triage based on risk accumulation and for detecting women-at-risk for adverse birth outcomes, M2C and R4U sum scores were compared. Overall accuracy of single risks was high (mean 93 %). Positive accuracy was lower (mean 46 %) with poorest accuracy for current psychiatric symptoms. Educational level and ethnicity partly explained poor accuracy (p < 0.05). Overall low PPS prevalence decreased the statistical power. For triage, M2C and R4U sum scores were interchangeable from sum scores of five or more (difference <1 %). The probability of adverse birth outcomes similarly increased with risk accumulation for both instruments, identifying 55-75 % of women-at-risk. The self-report M2C and the professional's R4U checklist seem interchangeable for triage of women-at-risk for PPS or adverse birth outcomes. However, the instruments seem to provide complementary information if used as a guidance to tailored risk-specific care.

The study aimed to examine the course of obsessive-compulsive disorder (OCD) across pregnancy and its impact on obstetric and neonatal outcomes. Women enrolled prior to 20-week gestation in a prospective, observational study. The Structured Clinical Interview for DSM-IV was completed to obtain lifetime Axis I diagnoses. A total of 56 women with OCD were followed at 1 to 3-month intervals through 52 weeks postpartum. Each visit, the Yale-Brown Obsessive Compulsive Scale (YBOCS), clinical assessment, and medication/exposure tracking were performed. Obstetric and neonatal data were abstracted from the medical record. In subjects with OCD, associations between perinatal obsessive-compulsive symptoms (OCSs) and outcomes were examined. Additionally, outcomes were compared to 156 matched psychiatric patients without OCD. Maternal age inversely correlated with the YBOCS scores across the study period (β = -0.5161, p = .0378). Cesarean section was associated with increased OCSs in the postpartum period compared to vaginal delivery (β = 5.3632, p = 0.043). No associations were found between severity of perinatal obsessions or compulsions and any specific obstetric or neonatal complications. Subjects without OCD had higher frequency of fetal loss compared to mothers with OCD (χ (2) = 4.03, p = 0.043). These novel prospective data fail to identify an association of OCSs with adverse outcomes. In contrast, there is an association of delivery method and younger maternal age with increased postnatal symptoms of OCD. Psychiatric subjects without OCD may have a higher risk of miscarriage and intrauterine fetal demise compared to subjects with OCD.

Longitudinal data collection initiated a decade ago as part of a successful NSF-CCLI grant proposal has resulted in a large - and growing - sample (200+) of students who report on their perceptions of self-improvement in Technology, Critical Thinking, and Quantitative Reasoning proficiencies upon completion of an introductory (200-level) GIS course at New Jersey City University, a Hispanic-Serving and Minority Institution in Jersey City, NJ. Results from student satisfaction surveys indicate that, not surprisingly, 80% of respondents report improved confidence in Technology Literacy. Critical Thinking proficiency is judged to be significantly improved by 60% of respondents. On the other hand, Quantitative Reasoning proficiency confidence is improved in only 30% of students. This latter finding has prompted the instructor to search for more easily recognizable (to the student) ways of embedding quantitative reasoning into the course, as it is obvious to any GIS professional that there is an enormous amount of quantitative reasoning associated with this technology. A second post-course questionnaire asks students to rate themselves in these STEM proficiency areas using rubrics. Results mirror those from the self-satisfaction surveys. On a 5-point Likkert scale, students tend to see themselves improving about one letter grade on average in each proficiency area. The self-evaluation rubrics are reviewed by the instructor and are judged to be accurate for about 75% of the respondents.

Aims There is controversy regarding the inclusion of patients with hypertension among cases of peripartum cardiomyopathy (PPCM), as the practice has contributed significantly to the discrepancy in reported characteristics of PPCM. We sought to determine whether hypertensive heart failure of pregnancy (HHFP) (i.e., peripartum cardiac failure associated with any form of hypertension) and PPCM have similar or different clinical features and outcome. Methods and Results We compared the time of onset of symptoms, clinical profile (including electrocardiographic [ECG] and echocardiographic features) and outcome of patients with HHFP (n = 53; age 29.6 ± 6.6 years) and PPCM (n = 30; age 31.5 ± 7.5 years). The onset of symptoms was postpartum in all PPCM patients, whereas it was antepartum in 85% of HHFP cases (p<0.001). PPCM was more significantly associated with the following features than HHFP (p<0.05): twin pregnancy, smoking, cardiomegaly with lower left ventricular ejection fraction on echocardiography, and longer QRS duration, QRS abnormalities, left atrial hypertrophy, left bundle branch block, T wave inversion and atrial fibrillation on ECG. By contrast, HHFP patients were significantly more likely (p<0.05) to have a family history of hypertension, hypertension and pre-eclampsia in a previous pregnancy, tachycardia at presentation on ECG, and left ventricular hypertrophy on echocardiography. Chronic heart failure, intra-cardiac thrombus and pulmonary hypertension were found significantly more commonly in PPCM than in HHFP (p<0.05). There were 5 deaths in the PPCM group compared to none among HHFP cases (p = 0.005) during follow-up. Conclusion There are significant differences in the time of onset of heart failure, clinical, ECG and echocardiographic features, and outcome of HHFP compared to PPCM, indicating that the presence of hypertension in pregnancy-associated heart failure may not fit the case definition of idiopathic PPCM.

Stress during pregnancy is a salient risk factor for adverse obstetric outcomes. Personal capital during pregnancy, defined as internal and social resources that help women cope with or decrease their exposure to stress, may reduce the risk of poor obstetric outcomes. Using data from the 2007 Los Angeles Mommy and Baby study (N = 3,353), we examined the relationships between the balance of stress and personal capital during pregnancy, or the stress-to-capital ratio (SCR), and adverse obstetric outcomes (i.e., pregnancy complications, preterm birth (PTB), low birth weight (LBW), and small for gestational age (SGA)). Women with a higher SCR (i.e., greater stress relative to personal capital during pregnancy) were significantly more likely to experience at least one pregnancy complication, PTB, and lower gestational age, but not LBW or SGA. Accounting for pregnancy complications completely mediated the association between the SCR and PTB. Our findings indicate that experiencing greater stress relative to personal capital during pregnancy is associated with an increased risk for pregnancy complications, PTB, and lower gestational age and that pregnancy complications may be a mechanism by which the SCR is related to adverse obstetric outcomes.

Context • Subclinical hypothyroidism (SCH) in pregnancy can be associated with increased complications in pregnant women and neurocognitive deficits in fetuses. Two recently published meta-analyses investigated the effects of levothyroxine (LT4) supplementation on pregnancy outcomes but did not report adverse complications and neonatal outcomes. Objectives • The study intended to assess the effects of LT4 supplementation in the treatment of pregnant women with thyroid dysfunction. Design • The research team performed a meta-analysis of randomized controlled trials (RCTs) published in PubMed, Embase, Web of Science, Chinese BioMedical Literature Service System, and China National Knowledge Infrastructure databases. Participants • Participants were infertile women who had SCH or were TPO antibody positive and who participated in the RCTs examined in the study. Intervention • The participants in the RCTs in the intervention groups received LT4 supplementation and the control groups received a placebo or no treatment. Outcome Measures • The main outcome measures included maternal outcomes-delivery rate, miscarriage rate, fertilization rate, clinical pregnancy rate, preeclampsia, gestational diabetes, and gestational hypertension-and neonatal outcomes-preterm delivery, lower birth weight, intrauterine growth restriction, neonatal death, and congenital malformations. Results were expressed as risk ratios with 95% confidence intervals. Results • A total of 14 RCTs involving 1918 patients were included in the meta-analysis. Compared with control treatments, LT4 supplementation significantly increased the delivery, clinical pregnancy, and fertilization rates. Moreover, LT4 significantly reduced the miscarriage rate, gestational diabetes, and gestational hypertension, but not preeclampsia. For the neonatal outcomes, the study found that the LT4 group had fewer preterm deliveries, birth weights <2500 g, deaths, and congenital malformations.

Adolescent pregnancy has been typically linked to a range of adverse outcomes for mother and child. In Australia, Aboriginal and Torres Strait Islander women have a higher proportion of adolescent births compared with other adolescent Australian women, and are at greater risk of poorer psychosocial and clinical outcomes if they are not well supported during pregnancy and beyond. Drawing on existing literature and consultations with young Aboriginal women and health professionals supporting pregnant Aboriginal women in Western Australia, this paper discusses the importance of creating models of antenatal care using a “social determinants of health” framework. Destigmatizing young parenthood and providing continuity of caregiver in culturally safe services, with culturally competent health professionals provides a means to encourage engagement with the health system and improve health outcomes for young mothers and their babies.

Recent data suggests that abnormal maternal pre-pregnancy body mass index (BMI) or gestational weight gain (GWG) is associated with unfavorable delivery outcomes. However, limited clinical evidence is available to support this correlation in China. Participating 510 mother-infant pairs were recruited from the Shanghai First Maternity and Infant Hospital, China, between January 1st and 30th 2016. Maternal pre-pregnancy BMI was categorized according to the China’s classification and GWG according to the 2009 Institute of Medicine recommendations (IOM). Linear regression tested the associations between pre-pregnancy BMI or GWG and length of gestation, birthweight, length, and head circumference. Logistic regression assessed the associations between pre-pregnancy BMI or GWG and macrosomic, small- (SGA) and large- (LGA) for-gestational-age infants. Overweight/obese women showed increased length of gestation and birthweight, but did not have a higher risk of macrosomic and LGA infants compared with normal weight women. Women with excessive GWG showed increased length of gestation, birthweight, length, and head circumference, and were more likely to deliver macrosomic and LGA infants compared with women with adequate GWG. Although a relatively low proportion of women from Shanghai area are overweight/obese or exhibit excessive GWG, both high pre-pregnancy BMI and excessive GWG influence perinatal outcomes.

The present article aimed to evaluate the impact of congenital Müllerian anomalies (MA) on twin pregnancy after 24 gestational weeks in Korean women. All records of twin pregnancies in a large maternity hospital in Korea between January 2005 and July 2013 were analyzed. Patients with monochorionic monoamniotic (MCMA) twins, non-Korean patients, patients with twins delivered prior to 24 gestational weeks, and patients with miscarriage of one fetus or intrauterine fetal death (IUFD) before 24 gestational weeks were excluded from data analysis. In total, 1,422 women with twin pregnancy were eligible for data analysis, including 17 (1.2%) who had a known congenital MA (septate uterus, bicornuate uterus, arcuate uterus, and unicornuate uterus). Except for the mode of conception, baseline demographics were similar between women with MA and those without MA. No significant differences were found in pregnancy outcomes of gestational age at delivery (p = .86), birth weight of smaller and larger twins (p = .54 and p = .65), and number of twins with birth weight <5th percentile for gestational age (p = .43).The rates of obstetrical complications such as pre-eclampsia, gestational diabetes mellitus (GDM), placenta previa, cerclage, IUFD, and postpartum hemorrhage were not significantly different between the two groups either. We concluded that the presence of congenital MA may not increase obstetrical risks in outcomes of pregnancy of twins delivered after 24 gestational weeks.

Allopurinol is a purine analogue that inhibits xanthine oxidase. It is mainly used for the treatment of hyperuricemia in patients with gout or tumor lysis syndrome. Experience with allopurinol in pregnancy is scarce. In 2011, Kozenko et al. reported on a child with multiple malformations after maternal treatment with allopurinol throughout pregnancy. Possible teratogenicity of allopurinol was proposed due to the similarity of the pattern of malformations in children with mycophenolate embryopathy. A possible common mechanism of both drugs, i.e. disruption of purine synthesis, was discussed. We report on the outcome of 31 prospectively ascertained pregnancies with allopurinol exposure at least during first trimester. Pregnancy outcomes were 2 spontaneous abortions, 2 elective terminations of pregnancy and 27 live born children. The overall rate of major malformations (3.7%) and of spontaneous abortions (cumulative incidence 11%, 95%-CI 3–40) were both within the normal range. However, there was one child with severe malformations including microphthalmia, cleft lip and palate, renal hypoplasia, low-set ears, hearing deficit, bilateral cryptorchidism, and micropenis. The striking similarity of the anomalies in this child and the case described by Kozenko et al. might be considered as a signal for teratogenicity. Thus, we would recommend caution with allopurinol treatment in the first trimester, until further data are available. PMID:23840514

Stressful life events experienced by pregnant women may lead to adverse obstetric outcomes. This study in Benghazi compared the rates of preterm, low-birth-weight and caesarean-section births at Al-Jamhouria hospital in the months before and during the armed conflict in Libya in 2011. Data were collected on all women admitted to the delivery ward during February to May 2011 (the months of the most active fighting in the city) (n = 7096), and October to December 2010 (the months immediately before the war) (n = 5935). Compared with the preceding months there was a significant rise during the conflict in the rate of deliveries involving preterm (3.6% versus 2.5%) and low-birth-weight (10.1% versus 8.5%) infants and caesarean sections (26.9% versus 25.3%). Psychosocial stress may have been a factor (among others) in an increase in negative pregnancy outcomes, and obstetric hospitals should be aware of these issues in times of war.

Background Previous research has linked polybrominated diphenyl ether (PBDE) exposure to poor birth outcomes and altered thyroid hormone levels. Objectives We examined whether maternal PBDE serum levels were associated with infant birth weight (g), head circumference (cm), birth length (cm), and birth weight percentile for gestational age. We explored the potential for a mediating role of thyroid hormone levels. Methods During 2008–2010, we recruited 140 pregnant women in their third trimester as part of a larger clinical obstetrics study known as Healthy Pregnancy, Healthy Baby. Blood samples were collected during a routine pre-natal clinic visit. Serum was analyzed for PBDEs, phenolic metabolites, and thyroid hormones. Birth outcome information was abstracted from medical records. Results In unadjusted models, a two-fold increase in maternal BDE 153 was associated with an average decrease in head circumference of 0.32 cm (95% CI: −0.53, −0.12); however, this association was attenuated after control for maternal risk factors. BDE 47 and 99 were similarly negatively associated but with 95% confidence intervals crossing the null. Associations were unchanged in the presence of thyroid hormones. Conclusions Our data suggest a potential deleterious association between maternal PBDE levels and infant head circumference; however, confirmatory studies are needed in larger sample sizes. A mediating role of thyroid hormones was not apparent. PMID:26431883

Purpose: Radiation has many potential long-term effects on cancer survivors. Female cancer patients may experience decreased fertility depending on the site irradiated. Oncologists should be aware of these consequences and discuss options for fertility preservation before initiating therapy. Methods and Materials: A comprehensive review of the existing literature was conducted. Studies reporting the outcomes for female patients treated with cranio-spinal, abdominal, or pelvic radiation reporting fertility, pregnancy, or neonatal-related outcomes were reviewed. Results: Cranio-spinal irradiation elicited significant hormonal changes in women that affected their ability to become pregnant later in life. Women treated with abdomino-pelvic radiation have an increased rate of uterine dysfunction leading to miscarriage, preterm labor, low birth weight, and placental abnormalities. Early menopause results from low-dose ovarian radiation. Ovarian transposition may decrease the rates of ovarian dysfunction. Conclusions: There is a dose-dependent relationship between ovarian radiation therapy (RT) and premature menopause. Patients treated with RT must be aware of the impact of treatment on fertility and explore appropriate options.

and data from the Danish National Birth Cohort (DNBC). The cohort was established in 1994 and baseline information from the enrolled 100,418 pregnancies was gathered from 1996 to 2002. At their first antenatal visit pregnant women were invited to participate in the cohort by their general practitioner. To contribute the women had to be pregnant, have intentions of carrying the pregnancy to term, reside in Denmark and speak Danish sufficiently well to participate in telephone interviews. When enrolled the women were asked to participate in two telephone interviews during pregnancy at approximately 12-14 and 30-32 weeks of gestation and two after birth when the child was six and 18 months old and a follow-up questionnaire at age seven years. Exposure to work-related stress was assessed based on information from the first interview on two questions regarding job control and job demands. These questions were interpreted as dimensions of demands and control, and hereafter used as a proxy for the dimensions of the job strain model by Karasek. Based on their answers, the women were divided into the four job strain categories: high strain, active, passive and low strain. Gestational age at birth, birthweight and congenital malformations were extracted from the Danish Medical Birth Register. The outcome variable on asthma and atopic dermatitis were based on maternal self-reports from the fourth (child 18 months) and fifth (child seven years old) interviews/questionnaires. All studies in the thesis were based on protocols describing methods, analyses etc. prior to handling. No associations were found between exposure to high strain (high demands, low control) during pregnancy and preterm birth, small for gestational age, congenital malformations and asthma in the children when compared to women exposed to low strain (low demands, high control). A protective effect on large for gestational age was observed when exposed to high strain, suggesting an impact on the birthweight

Context Video games represent a multibillion-dollar industry in the U.S. Although video gaming has been associated with many negative health consequences, it may also be useful for therapeutic purposes. The goal of this study was to determine whether video games may be useful in improving health outcomes. Evidence acquisition Literature searches were performed in February 2010 in six databases: the Center on Media and Child Health Database of Research, MEDLINE, CINAHL, PsycINFO, EMBASE, and the Cochrane Central Register of Controlled Trials. Reference lists were hand-searched to identify additional studies. Only RCTs that tested the effect of video games on a positive, clinically relevant health consequence were included. Study selection criteria were strictly defined and applied by two researchers working independently. Study background information (e.g., location, funding source), sample data (e.g., number of study participants, demographics), intervention and control details, outcomes data, and quality measures were abstracted independently by two researchers. Evidence synthesis Of 1452 articles retrieved using the current search strategy, 38 met all criteria for inclusion. Eligible studies used video games to provide physical therapy, psychological therapy, improved disease self-management, health education, distraction from discomfort, increased physical activity, and skills training for clinicians. Among the 38 studies, a total of 195 health outcomes were examined. Video games improved 69% of psychological therapy outcomes, 59% of physical therapy outcomes, 50% of physical activity outcomes, 46% of clinician skills outcomes, 42% of health education outcomes, 42% of pain distraction outcomes, and 37% of disease self-management outcomes. Study quality was generally poor; for example, two thirds (66%) of studies had follow-up periods of <12 weeks, and only 11% of studies blinded researchers. Conclusions There is potential promise for video games to improve

Objective Heparin can modulate proteins, and influence processes involved in implantation and trophoblastic development. This study aimed to assess the improvement of clinical pregnancy and implantation rates after local intrauterine injection of low-molecular-weight heparin (LMWH) in patients undergoing intracytoplasmic sperm injection (ICSI). Methods A randomised case/control design was followed in women scheduled for ICSI. The study arm was injected with intrauterine LMWH during mock embryo transfer immediately following the ovum pickup procedure, while the control arm was given an intrauterine injection with a similar volume of tissue culture media. Side effects, the clinical pregnancy rate, and the implantation rate were recorded. Results The pregnancy rate was acceptable (33.9%) in the LMWH arm with no significant reported side effects, confirming the safety of the intervention. No statistically significant differences were found in the clinical pregnancy and implantation rates between both groups (p=0.182 and p=0.096, respectively). The odds ratio of being pregnant after intrauterine injection with LMWH compared to the control group was 0.572 (95% confidence interval [CI], 0.27−1.22), while the risk ratio was 0.717 (95% CI, 0.46−1.13; p=0.146). No statistical significance was found between the two groups in other factors affecting implantation, such as day of transfer (p=0.726), number of embryos transferred (p=0.362), or embryo quality. Conclusion Intrauterine injection of LMWH is a safe intervention, but the dose used in this study failed to improve the outcome of ICSI. Based on its safety, further research involving modification of the dosage and/or the timing of administration could result in improved ICSI success rates. PMID:28090465

Previous thrombosis, diagnosis of systemic lupus erythematosus (SLE) and triple antiphospholipid (aPL) antibody positivity have recently been found to be independent factors associated to pregnancy failure during conventional therapy in women with antiphospholipid syndrome (APS). This study aimed to assess the effect of various treatment strategies on pregnancy outcomes in women with APS and the risk factors for pregnancy failure. One hundred ninety-six pregnancies of 156 patients diagnosed with APS were analysed: 118 (60.2%) of these had previous thrombosis, 81 (41.3%) were diagnosed with SLE, and 107 (54.6%) had triple aPL positivity. One hundred seventy-five (89.3%) were treated with conventional therapies (low-dose aspirin [LDA] or prophylactic doses of heparin + LDA or therapeutic doses of heparin + LDA), while 21 (10.7%) were prescribed other treatments in addition to conventional therapy. The pregnancies were classified into seven risk profiles depending on the patients' risk factors - thrombosis, SLE, and triple aPL positivity - and their single, double or triple combinations. It was possible to find significant difference in outcomes correlated to treatments only in the thrombosis plus triple aPL positivity subset, and logistic regression analysis showed that additional treatments were the only independent factor associated to a favourable pregnancy outcome (odds ratio=9.7, 95% confidence interval=1.1-88.9, p-value<0.05). On the basis of this retrospective study, we found that APS pregnant patients with thrombosis and triple aPL positivity treated with additional therapy had a significant higher live-birth rate with respect to those receiving conventional therapy alone.

The Zapatista armed conflict began in the state of Chiapas, Mexico, in 1994, and overlaps pre-existing local disputes about land, religion, and other issues. Related disruptions in access to and utilization of health services have been alleged to have compromised local health status, particularly in vulnerable subgroups such as indigenous women and infants. The study objective was to measure maternal and perinatal mortality ratios and utilization of pregnancy-related health services in the region affected by the Zapatista conflict, and to describe associations between these primary outcome measures, socioeconomic and demographic factors, and factors associated with inter-party and intra-community conflict. A cross-sectional, population-based survey was conducted in 46 communities in three regions. The study subjects were 1227 women, 13-49 years old, who had been pregnant during the preceding 2 years (1999-2001). Principal outcome measures were maternal and perinatal mortality, and site of delivery. Secondary analyses explored associations between primary outcomes and socioeconomic, demographic, and conflict-related factors. Most births (87.1%) occurred at home. The crude observed maternal and perinatal mortality ratios were 607/100,000 and 23.5/1000 live births, respectively. Those who died had difficulty accessing emergency obstetrical care. Both home birth and mortality were associated with descriptors of intra-community conflict. Observed maternal and perinatal mortality ratios were substantially higher than those officially reported for Mexico or Chiapas. Reduction of high reproductive mortality ratios will require attention to socioeconomic and conflict-related problems, in addition to improved access to emergency obstetrical services.

In the absence of intervention, the rate of vertical transmission of HIV can range from 15-45%. With the inclusion of antiretroviral drugs during pregnancy and the choice of delivery route this amounts to less than 2%. However ARV use during pregnancy has generated several questions regarding the adverse effects of the gestational and neonatal outcome. This study aims to analyze the risk factors for vertical transmission of HIV-1 seropositive pregnant women living in Rio Grande and the influence of the use of ARVs in pregnancy outcome. Among the 262 pregnant women studied the rate of vertical transmission of HIV was found to be 3.8%. Regarding the VT, there was a lower risk of transmission when antiretroviral drugs were used and prenatal care was conducted at the referral service. However, the use of ART did not influence the outcome of pregnancy. However, initiation of prenatal care after the first trimester had an influence on low birth weight, as well as performance of less than six visits increased the risk of prematurity. Therefore, the risk factors analyzed in this study appear to be related to the realization of inadequate pre-natal and maternal behavior. PMID:24626415

To promote the pregnancy rate of in vitro fertilization-embryo transfer (IVF-ET), we proposed to examine the differentially expressed gene during pregnancy success and failure. We used high-sequencing technology to characterize and compare the gene expression profiles of pregnancy success and pregnancy failure patients during 3 different stages: before IVF-ET (stage I), after ovarian stimulation (stage II), and day 15 after embryo transfer (stage III). Selected data from RNA-sequencing experiments were validated by quantitative real-time polymerase chain reaction (qRT-PCR). A total of 282, 208, and 372 genes in stages I, II, and III, respectively, were differentially expressed between pregnancy success and pregnancy failure, respectively. Through confirmation with qRT-PCR, compared to pregnancy failure, we demonstrated much lower level of major histocompatibility complex, human leukocyte antigen class I A, and an much higher level of human leukocyte antigen, class II DQ α1 (HLA-DQA1) in pregnancy success, although the HLA-DQA1 decreased with development duration of pregnancy. Interleukin 1β increased with the development duration of pregnancy in pregnancy failure group and was much higher than that in pregnancy success group. Hemoglobin δ decreased with the development duration of pregnancy in pregnancy failure women and maintained in a lower level in stage I and II but dramatically increased to a much higher level in stage III in pregnancy success women. Minichromosome maintenance complex component 4 significantly increased in stage III in pregnancy failure but not in pregnancy success women. The altered expression of genes implicated in immune response and inflammation, oocyte meiosis, rhythmic process, and so on. Therefore, the current results provide a strong basis for future research to expound the molecular mechanism coping with pregnancy outcome.

Introduction Since 2010, WHO has recommended oral cholera vaccines as an additional strategy for cholera control. During a cholera episode, pregnant women are at high risk of complications, and the risk of fetal death has been reported to be 2–36%. Due to a lack of safety data, pregnant women have been excluded from most cholera vaccination campaigns. In 2012, reactive campaigns using the bivalent killed whole-cell oral cholera vaccine (BivWC), included all people living in the targeted areas aged ≥1 year regardless of pregnancy status, were implemented in Guinea. We aimed to determine whether there was a difference in pregnancy outcomes between vaccinated and non-vaccinated pregnant women. Methods and Findings From 11 November to 4 December 2013, we conducted a retrospective cohort study in Boffa prefecture among women who were pregnant in 2012 during or after the vaccination campaign. The primary outcome was pregnancy loss, as reported by the mother, and fetal malformations, after clinical examination. Primary exposure was the intake of the BivWC vaccine (Shanchol) during pregnancy, as determined by a vaccination card or oral history. We compared the risk of pregnancy loss between vaccinated and non-vaccinated women through binomial regression analysis. A total of 2,494 pregnancies were included in the analysis. The crude incidence of pregnancy loss was 3.7% (95%CI 2.7–4.8) for fetuses exposed to BivWC vaccine and 2.6% (0.7–4.5) for non-exposed fetuses. The incidence of malformation was 0.6% (0.1–1.0) and 1.2% (0.0–2.5) in BivWC-exposed and non-exposed fetuses, respectively. In both crude and adjusted analyses, fetal exposure to BivWC was not significantly associated with pregnancy loss (adjusted risk ratio (aRR = 1.09 [95%CI: 0.5–2.25], p = 0.818) or malformations (aRR = 0.50 [95%CI: 0.13–1.91], p = 0.314). Conclusions In this large retrospective cohort study, we found no association between fetal exposure to BivWC and risk of pregnancy loss or

Background Advances in cardiac surgery and congenital cardiology have led to an increasing number of women with congenital heart disease (CHD) reaching childbearing age. In general, cardiologists recommend vaginal delivery for women with CHD to avoid complications from Caesarean section as many women with CHD tolerate vaginal delivery well. Methods and Results This is a single-center study comparing mode of delivery, pregnancy outcome, indications for Caesarean section and induction of labor between women with and without CHD. A historical cohort study was conducted including 116 patients with CHD. An individual threefold matching with 348 women without CHD was carried out. Caesarean section was performed in 46.6% of pregnancies with CHD (33.6% without CHD, P = 0.012). Primary Caesarean section increases with severity of CHD (P = 0.036), 33.3% of women with CHD had primary planned Caesarean section due to cardiac reasons. Induction of labor was performed in 45.7% of attempted vaginal deliveries in women with CHD (27.9% without CHD, P = 0.001). Lower mean birth weight (P = 0.004) and Small for Gestational Age (SGA) (P < 0.001) were more common in women with CHD. One CHD patient suffered from postpartum hemorrhage. Conclusions Concerns about maternal deterioration resulting in higher rates of induction of labor seem unjustified in most cases. Along with a possible reduction of Caesarean section on maternal request, a reduction of planned vaginal delivery may be expedient in reducing the rate of Caesarean section in women with CHD.

Intrauterine presence of Porphyromonas gingivalis (Pg), a common oral pathobiont, is implicated in preterm birth. Our aim was to determine if the location of Pg within placental and/or umbilical cord sections was associated with a specific delivery diagnosis at preterm delivery (histologic chorioamnionitis, chorioamnionitis with funisitis, preeclampsia, and preeclampsia with HELLP-syndrome, small for gestational age). The prevalence and location of Pg within archived placental and umbilical cord specimens from preterm (25 to 32 weeks gestation) and term control cohorts were evaluated by immunofluorescent histology. Detection of Pg was performed blinded to pregnancy characteristics. Multivariate analyses were performed to evaluate independent effects of gestational age, being small for gestational age, specific preterm delivery diagnosis, antenatal steroids, and delivery mode, on the odds of having Pg in the preterm tissue. Within the preterm cohort, 49 of 97 (51%) placentas and 40 of 97 (41%) umbilical cord specimens were positive for Pg. Pg within the placenta was significantly associated with shorter gestation lengths (OR 0.63 (95%CI: 0.48–0.85; p = 0.002) per week) and delivery via caesarean section (OR 4.02 (95%CI: 1.15–14.04; p = 0.03), but not with histological chorioamnionitis or preeclampsia. However, the presence of Pg in the umbilical cord was significantly associated with preeclampsia: OR 6.73 (95%CI: 1.31–36.67; p = 0.02). In the term cohort, 2 of 35 (6%) placentas and no umbilical cord term specimens were positive for Pg. The location of Pg within the placenta was different between preterm and term groups in that Pg within the villous mesenchyme was only detected in the preterm cohort, whereas Pg associated with syncytiotrophoblasts was found in both preterm and term placentas. Taken together, our results suggest that the presence of Pg within the villous stroma or umbilical cord may be an important determinant in Pg-associated adverse pregnancy

The aim of this study was to evaluate and elucidate the impact of intimate partner violence (IPV) on women's reproductive health and pregnancy outcomes taking into account data from various countries. The search of the literature was made in MEDLINE database service for the years 2002-2008. Original articles, reviews, surveys, clinical trials and investigations pertinent to the theme were considered for this review. The lifetime physical or sexual IPV or both varied from 15% to 71% in many countries. Adolescent violence, negative emotionality and quality of the relationship with the intimate partner were associated with genesis of IPV, besides demographic, social and structural difference in attitudes. IPV affected woman's physical and mental health, reduced sexual autonomy, increased risk for unintended pregnancy and multiple abortions. Risk for sexual assault decreased by 59% or 70% for women contacting the police or applying for a protection order, respectively. Quality of life of IPV victims was found significantly impaired. Women battered by IPV reported high levels of anxiety and depression that often led to alcohol and drug abuse. Violence on pregnant women significantly increased risk for low birth weight infants, pre-term delivery and neonatal death and also affected breast-feeding postpartum. Women preferred an active role to be played by healthcare providers in response to IPV disclosure. Gynaecologists reported interventions for the patient disclosing IPV and provided treatment for their physical and emotional complaints. Educating and empowering women and upgrading their socioeconomic status may abate the incidence of IPV. Women should also seek protection against IPV.

Maternal prepregnancy obesity is associated with impaired cardiometabolic health in offspring. Whether these associations reflect direct intrauterine causal mechanisms remains unclear. In a population-based prospective cohort study among 4871 mothers, fathers, and their children, we examined the associations of both maternal and paternal prepregnancy body mass index (BMI) with childhood body fat distribution and cardiometabolic outcomes and explored whether any association was explained by pregnancy, birth, and childhood factors. We measured childhood BMI, total body and abdominal fat distribution, blood pressure, and blood levels of lipids, insulin, and C-peptide at the age of 6 years. We observed that higher maternal and paternal prepregnancy BMI were associated with higher childhood BMI, total body and abdominal fat mass measures, systolic blood pressure, and insulin levels and lower high-density lipoprotein cholesterol levels (P<0.05). Stronger associations were present for maternal than paternal BMI, with statistical support for heterogeneity between these associations. The associations for childhood fat mass and cardiometabolic outcomes attenuated after adjustment for childhood current BMI. Compared with children from normal-weight mothers, those from obese mothers had increased risks of childhood overweight (odds ratio, 3.84 [95% confidence interval, 3.01-4.90]) and clustering of cardiometabolic risk factors (odds ratio, 3.00 [95% confidence interval, 2.09-4.34]). Smaller effect estimates for these outcomes were observed for paternal obesity. In conclusion, higher maternal and paternal prepregnancy BMI were associated with an adverse cardiometabolic profile in offspring, with stronger associations present for maternal prepregnancy BMI. These findings suggest that maternal prepregnancy BMI may influence the cardiometabolic health of offspring through direct intrauterine mechanisms.

Objective Disturbed sleep and depression are potential risk factors for pregnancy complications. Both conditions are noted to dysregulate biological pathways responsible for maintaining homeostatic balance and pregnancy health. Depression during pregnancy is associated with poor sleep. Thus, we explored whether disturbed sleep was associated with inflammatory cytokines and risk for adverse pregnancy outcomes, as well as whether depression augmented the sleep-cytokine relationship thereby additively contributing to risk for adverse outcomes. Methods Interview-assessed sleep and plasma cytokine concentrations were evaluated in a cohort of depressed and non-depressed pregnant women (N= 168) at 20 and 30 weeks gestation. Outcomes evaluated included preterm birth, birth weight, and peripartum events. Results Among depressed women, short sleep duration (< 7 hours) was associated with higher IL-8 across time (β=.506, p = .001), poor sleep efficiency (< 85%) was associated with higher IL-6 (β=.205, p = .006), and daytime naps were associated with higher TNF-α (β=.105, p =.024). Aspects of poor sleep were associated with having a lower weight baby (ps < 053). Among depressed women, IFN-γ increased risk for preterm birth (OR = 1.175, p = .032). Trends for IL-6 and higher birth weight (β = 105.2, p = .085); IFN-γ and lower birth weight (β = −19.92, p < .069); and increased IL-8 and babies weighing < 4000g, (OR =.72, p < .083) were observed. Conclusions Although speculative, disturbed sleep may disrupt normal immune processes and contribute to adverse pregnancy outcomes. Exploratory analyses indicate depression modifies these relationships. PMID:23864582

A considerable literature has been accumulated regarding the relation of psychological factors to in-vitro fertilization outcome. However, study findings have been inconsistent, and the association between psychological stress and in-vitro fertilization outcomes is still unclear. The aim of the authors in this study was to examine the relation of infertility-related stress, anxiety, and depressive symptoms to in-vitro fertilization outcome. The sample consisted of 160 women with fertility problems undergoing fertility treatment in a public hospital in Athens, Greece between November 2008 and July 2009. The relation of infertility-related stress, anxiety, and depressive symptoms to in-vitro fertilization outcome was assessed by using hierarchical, sequential logistic regression, while controlling for the effects of relevant biomedical factors. After the embryo transfer, 41 women (26%) had a positive pregnancy outcome. Logistic regression analyses revealed that, controlling for biomedical factors (age, number of oocytes retrieved, and embryos transferred) infertility-specific stress (OR = 0.964, p = .011) and nonspecific anxiety (OR = 0.889, p = .006) were negatively associated with a positive pregnancy outcome after IVF. Psychological stress was negatively associated with in-vitro fertilization outcome, after controlling for biomedical variables. Fertility treatment protocols should consider including counselling interventions to potentially mitigate adverse effects of stress.

The autoimmune lymphoproliferative syndrome (ALPS) is a disorder of abnormal lymphocyte survival caused by the dysregulation of the Fas apoptotic pathway. The Fas gene is expressed at the maternal-fetal interface and is involved in the regulation of immune response and implantation. Altered Fas expression may result in altered apoptosis and, ultimately, affect both the immune response and implantation; it is in fact associated with recurrent pregnancy loss, preterm premature rupture of membranes and pre-eclampsia. Currently, there are over 500 cases of ALPS reported worldwide from various racial and ethnic backgrounds. Up to date, the published work contains no specific reports on pregnancy outcome in women affected by ALPS. We present a case of full-term uneventful pregnancy in a patient affected by ALPS. A specific clinical follow-up in a pregnant woman with primary immunologic disease is suggested.

Uterine fibroids are considered to be the most frequent female benign tumours. Fibroids affect mainly women of reproductive age. The most frequently reported signs and symptoms of fibroids include disturbances of the menstrual cycle such as heavy bleeding and painful menstruation, pelvic masses associated with pelvic pain, urinary problems or constipation, as well as infertility and recurrent pregnancy loss. The mainstay of fibroid treatment is still surgery. However, many patients seek alternative treatment options for fibroids, to preserve their uterus and fertility. One of the most important alternative treatment options for fibroids is uterine artery embolisation (UAE). However, there are some concerns that UAE may negatively influence ovarian function and even result in premature menopause. Moreover, the use of UAE in patients with future reproductive plans is still controversial, due to the possible pregnancy complications. The purpose of this review is to summarise the current knowledge regarding the possible influence of UAE on fertility, pregnancy outcome, and ovarian reserve. PMID:28250724

Advanced abdominal pregnancy is an extremely rare condition that poses diagnostic and management challenges. A high index of suspicion and careful assessment of the patient's symptoms, supplemented with obstetric ultrasound, and magnetic resonance imaging, are crucial for timely diagnosis and management to prevent life-threatening complications. The presence of periviable fetuses in advanced abdominal pregnancies increases the challenge to achieve a balance between maternal and fetal benefits and risks. Early diagnosis and management decisions via a multidisciplinary approach and planned delivery are of paramount importance to minimize complications and achieve favorable maternal and fetal outcomes. Even in the setting of oligohydramnios and suspected preterm premature rupture of membranes, in-patient conservative management and an individualized planned surgical approach that includes removing or leaving the placenta in place are appropriate for managing the periviable abdominal pregnancy.

Malignant germ cell tumors (MGCT) are a rare type of ovarian cancer with poorly understood behavior during pregnancy. This systematic review evaluated feto-maternal outcomes and management patterns of 102 ovarian MGCT-complicated pregnancies identified in PubMed/MEDLINE. Mean age was 25.8. The most common histology type was dysgerminoma (38.2%) followed by yolk sac tumor (30.4%). Abdomino-pelvic pain (35.3%) was the most common symptom. The majority were stage I disease (76.4%) with a mean tumor size of 17.9cm. Most cases had live births (77.5%) at term (56.6%). Tumor surgery without fetal conservation took place in 22 (21.6%) cases (Group 1). This group was characterized by the first trimester tumor detection and intervention, non-viable pregnancy, and frequent concurrent hysterectomy. There were 59 (57.8%) cases which underwent expectant management of pregnancy: mean delay 16.4 weeks for 46 (45.1%) cases with tumor surgery and fetal conservation (Group 2); and 7.8 weeks for 13 (12.7%) cases with tumor surgery after delivery (Group 3). The live birth rate in Groups 2 and 3 was 98.3%. There were 21 (20.6%) cases in which the tumor was incidentally found intra/postpartum (Group 4). Group 2 showed the highest 5-year overall survival rate (92.8%) followed by Group 4 (79.5%), Group 3 (71.4%), and Group 1 (56.2%, p=0.028). Group 1 had more advanced-stage disease when compared to Group 2 (proportion of stages II-IV disease, 36.4% versus 11.4%, p=0.023). In multivariate analysis, age ≤20 (p=0.032) and stages II-IV (p=0.02) remained independent prognosticators for decreased overall survival in all cases. Expectant management of pregnancy was not associated with poor survival outcome in multivariate analysis (p=0.43). In conclusion, our analysis demonstrated that timing of tumor intervention and delivery significantly impacted feto-maternal outcome of ovarian MGCT-complicated pregnancies. It is suggested that early detection and tumor intervention with expectant

Introduction Poor dietary intake during pregnancy can have negative repercussions on the mother and fetus. This study therefore aims to explore the dietary diversity (DD) of pregnant women and its associations with pregnancy outcomes among women in Northern Ghana. The main outcome variables to be measured are gestational weight gain and birth weight. Methods and analysis A prospective cohort study design will be used and 600 pregnant women in their first trimester will be systematically recruited at health facilities and followed until delivery. In three follow-up visits after recruitment, information on sociodemographic and general characteristics, physical activity (International Physical Activity Questionnaire (IPAQ) short form, dietary intake (24-hour food recall), anthropometry and pregnancy outcomes will be collected. DD will be measured three times using the minimum DD-women (MDD-W) indicator and the mean of the three values overall will be used to determine low (<5 food groups) and high (≥5 food groups) DD. Data will be analysed using SPSS. Comparisons between groups (categorical data) will be made using the χ2 test for proportions, and t-tests and ANOVA will be performed on continuous variables. Regression analysis will be used to identify independent outcome predictors while controlling for possible confounding factors. The results may help to identify differences in DD between healthy and unhealthy pregnancy outcomes. Ethics and dissemination The study protocol has been approved by the ethics committee of Tehran University of Medical Sciences and the ethical review committee of the Tamale Teaching Hospital. Written informed consent will be obtained from all subjects. The results will be published in due course. PMID:27655259

It is the position of the Academy of Nutrition and Dietetics that women of childbearing age should adopt a lifestyle optimizing health and reducing risk of birth defects, suboptimal fetal development, and chronic health problems in both mother and child.Components leading to healthy pregnancy outcome include healthy pre-pregnancy weight, appropriate weight gain and physical activity during pregnancy, consumption of a wide variety of foods, appropriate vitamin and mineral supplementation, avoidance of alcohol and other harmful substances, and safe food handling. Nutrition assessment needs to encompass changes in anthropometric,biochemical, and clinical indicators throughout pregnancy. Pregnant women should gain weight according to the 2009 Institute of Medicine Guidelines. Energy needs are no higher than the Estimated Energy Requirement for nonpregnant women until the second trimester; thereafter, the extra energy need per day is 340 kcal and 452 kcal in the second and third trimesters,respectively. Using the 2010 Dietary Guidelines for Americans, registered dietitian nutritionists and dietetics technicians, registered,can help pregnant women select a food plan based on age, physical activity, trimester, weight gain, and other considerations.Women are encouraged to participate in at least 150 minutes of moderate-intensity aerobic activity spread throughout the week or 30 minutes of moderately intense exercise on most days of the week.When good food choices are made, food consumption to meet extra energy needs and the increased absorption and efficiency of nutrient utilization that occurs in pregnancy are generally adequate to meet most nutrient needs. However, vitamin and mineral supplementation may be important in vulnerable cases including food insecurity; alcohol, tobacco, or other substance dependency; anemia; strict vegetarian (vegan) diet; or poor eating habits. Multiple strategies are needed to support healthy lifestyles for all women, from preconception

Summary Background There is a growing interest in examining death rates associated with different pregnancy outcomes for time periods beyond one year. Previous population studies, however, have failed to control for complete reproductive histories. In this study we seek to eliminate the potential confounding effect of unknown prior pregnancy history by examining mortality rates associated specifically with first pregnancy outcome alone. We also examine differences in mortality rates associated with early abortion and late abortions (after 12 weeks). Material/Method Medical records for the entire population of women born in Denmark between 1962 and 1991 and were alive in 1980, were linked to death certificates. Mortality rates associated with first pregnancy outcomes (delivery, miscarriage, abortion, and late abortion) were calculated. Odds ratios examining death rates based on reproductive outcomes, adjusted for age at first pregnancy and year of women’s births, were also calculated. Results A total of 463,473 women had their first pregnancy between 1980 and 2004, of whom 2,238 died. In nearly all time periods examined, mortality rates associated with miscarriage or abortion of a first pregnancy were higher than those associated with birth. Compared to women who delivered, the age and birth year adjusted cumulative risk of death for women who had a first trimester abortion was significantly higher in all periods examined, from 180 days (OR=1.84; 1.11 <95% CI <3.71) through 10 years (1.39; 1.22 <95% CI <1.61), as was the risk for women who had abortions after 12 weeks from one year (OR=4.31; 2.18 <95% CI <8.54) through 10 years (OR=2.41; 1.56 <95% CI <2.41). For women who miscarried, the risk was significantly higher for cumulative deaths through 4 years (OR=1.75; 1.34 <95% CI <2.27) and at 10 years (OR=1.48; 1.18 <95% CI <1.85). Conclusions Compared to women who delivered, women who had an early or late abortion had significantly higher mortality rates within 1

Objective To explore the joint and independent effects of gestational weight gain (GWG) and pre-pregnancy body mass index (BMI) on pregnancy outcomes in a population of Chinese Han women and to evaluate pregnant women’s adherence to the 2009 Institute of Medicine (IOM) gestational weight gain guidelines. Methods This was a multicenter, retrospective cohort study of 48,867 primiparous women from mainland China who had a full-term singleton birth between January 1, 2011 and December 30, 2011. The independent associations of pre-pregnancy BMI, GWG and categories of combined pre-pregnancy BMI and GWG with outcomes of interest were examined using an adjusted multivariate regression model. In addition, women with pre-pregnancy hypertension were excluded from the analysis of the relationship between GWG and delivery of small-for-gestational-age (SGA) infants, and women with gestational diabetes (GDM) were excluded from the analysis of the relationship between GWG and delivery of large-for-gestational-age (LGA) infants. Results Only 36.8% of the women had a weight gain that was within the recommended range; 25% and 38.2% had weight gains that were below and above the recommended range, respectively. The contribution of GWG to the risk of adverse maternal and fetal outcomes was modest. Women with excessive GWG had an increased likelihood of gestational hypertension (adjusted OR 2.55; 95% CI = 1.92–2.80), postpartum hemorrhage (adjusted OR 1.30; 95% CI = 1.17–1.45), cesarean section (adjusted OR 1.31; 95% CI = 1.18–1.36) and delivery of an LGA infant (adjusted OR 2.1; 95% CI = 1.76–2.26) compared with women with normal weight gain. Conversely, the incidence of GDM (adjusted OR 1.64; 95% CI = 1.20–1.85) and SGA infants (adjusted OR 1.51; 95% CI = 1.32–1.72) was increased in the group of women with inadequate GWG. Moreover, in the obese women, excessive GWG was associated with an apparent increased risk of delivering an LGA infant. In the women who were
This paper addresses four questions: What are the effects of reducing class size? How important are these effects? How can we explain these effects? and How can we improve the outcomes when class sizes are reduced? A major aim is to provide directions for resolving the paradox as to "Why reducing class size has not led to major improvements in…

Evaluation of human data regarding the outcomes of topical-retinoid-exposed pregnancies is important in terms of counselling pregnant women with inadvertent exposure. The objective of this study was thus to determine whether exposure to topical retinoids leads to an increase in the risk of adverse pregnancy outcomes. We carried out a search using the Medline, Embase, Web of Science and Cochrane Central Register of Controlled Trials databases from inception to 4 December 2014. The selection, review and quality assessment of the studies were carried out by two independent reviewers according to predetermined inclusion criteria. Odds ratios (ORs) were calculated by the random effects method. This meta-analysis, including a total of 654 pregnant women who were exposed to topical retinoids, and 1375 unexposed control pregnant women, did not detect significant increases in rates of major congenital malformations [OR 1·22, 95% confidence interval (CI) 0·65-2·29], spontaneous abortions (OR 1·02, 95% CI 0·64-1·63), stillbirth (OR 2·06, 95% CI 0·43-9·86), elective termination of pregnancy (OR 1·89, 95% CI 0·52-6·80), low birthweight (OR 1·01, 95% CI, 0·31-3·27) or prematurity (OR 0·69, 95% CI 0·39-1·23). No significant heterogeneity was detected among the studies for the evaluated outcomes. The present meta-analysis ruled out a major increase in the rates of major congenital malformations, spontaneous abortions, low birthweight and prematurity. This result may be used primarily in reassuring women who were inadvertently exposed to topical retinoids during their pregnancy. However, the statistical power is not adequate to justify the use of topical retinoids during pregnancy.

The aim of this study was to analyse effects that the degree of depression have on the life style variables, nutrient intake, iron indices and pregnancy outcome. Subjects were 114 pregnant women who were receiving prenatal care at a hospital in Seoul. We collected data for general characteristics and lifestyle variables from general survey instrument and for depression score from the questionnaire on depression. Dietary intakes of subjects were estimated by 24 hour dietary recall method. Also we analysed iron indices and pregnancy outcomes. We classified subjects by 10 point, which was the average depression score, into two groups [Low depression score group (LS) : High depression score group (HS)]. As to the intakes of total calcium, plant-calcium, plant-iron, potassium, total folate and dietary folate, LS group was far higher than HS group (P < 0.05, P < 0.05, P < 0.01, P < 0.001, P < 0.05, and P < 0.01, respectively). As to pre-pregnancy alcohol drinking, LS group had 41.9% in non-drinker, which was far higher than 28% in HS group in non-drinker (P < 0
