    The Pregnancy Nutrition Surveillance System is a useful tool in monitoring Healthy People 2010 objectives and is intended to provide a framework for analyzing data on the nutritional status and behavioral risk factors of pregnant women and the association to birth outcome. The data are useful to health professionals in providing prenatal care and developing programs to reduce pregnancy-related health risks.

    Mindfulness is known to decrease psychological distress. Possible benefits in pregnancy have rarely been explored. Our aim was to examine the prospective association of mindfulness with autonomic nervous system function during pregnancy and with later infant social-emotional development. Pregnant women (N = 156) completed self-report mindfulness and emotional distress questionnaires, and had their autonomic function assessed in their first and third trimesters, including heart rate (HR), indices of heart rate variability (HRV), preejection period (PEP), and systolic (SBP) and diastolic blood pressure (DBP). The social-emotional development of 109 infants was assessed at 4 months of age. More mindful pregnant women had less prenatal and postnatal emotional distress (p mindful mothers, parasympathetic activity decreased less (RMSSD: p = .01; HF HRV: p = .03) and sympathetic activity (inversely related to PEP) increased less (PEP: p = .02) between trimesters. Their offspring displayed less negative social-emotional behavior (p = .03) compared to offspring of less mindful mothers. Mindfulness in pregnancy was associated with ANS changes likely to be adaptive and with better social-emotional offspring development. Interventions to increase mindfulness during pregnancy might improve maternal and offspring health, but randomized trials are needed to demonstrate this.

    Systemic lupus erythematosus is a chronic inflammatory disease, resulting from an auto-immune dysfunction. The etiology of this disease is unknown. It frequently occurs in women of childbearing age. Pregnancy in patients with systemic lupus erythematosus may be associated with several complications (maternal, obstetrical and fetal). The prognosis for both mother and child is better when systemic lupus erythematosus has been quiescent for at least six months before pregnancy. Thus, preconceptional assessment and management is crucial for helping women to achieve a period of disease remission before pregnancy as well as for allowing an adjustment of therapy. Maternal health and fetal development should be closely monitored during pregnancy. These patients should be surveilled by a multidisciplinary team (obstetrician, rheumatologist or internist, nephrologist if necessary and a pediatrician), in a tertiary care hospital. Antiphospholipid syndrome, positivity for anti-SSA/Ro or anti-SSB/LA antibodies, hypertension or renal involvement are associated with an increase of adverse pregnancy outcomes. In this article the authors review the main aspects of Systemic lupus erythematosus (SLE) and pregnancy.

    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 fetal 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.

    Systemic lupus erythematosus (SLE) is an autoimmune disease with a strong female predilection. Pregnancy remains a commonly encountered but high-risk situation in this setting. Both maternal and fetal mortality and morbidity are still significantly increased despite improvements in outcomes. Maternal morbidity includes higher risk of disease flares, preeclampsia and other pregnancy-related complications. Fetal issues include higher rates of preterm birth, intrauterine growth restriction, and neonatal lupus syndromes. Treatment options during pregnancy are also limited and maternal benefit has to be weighed against fetal risk. A coordinated approach, with close monitoring by a multidisciplinary team, is essential for optimal outcomes.

    The Interactive Systems Framework for Dissemination and Implementation (ISF) is a multi-system framework that can guide research-to-practice efforts by building and supporting the work of three interacting systems: the Prevention Delivery, Support, and Synthesis and Translation Systems. The Synthesis and Translation system is vital to bridging science and practice, yet how to develop it and train support system partners to use it is under-researched. This article bridges this gap by offering a case example of the planning, development, and use of a synthesis and translation product called Promoting Science-based Approaches to Teen Pregnancy Prevention using Getting To Outcomes. The case presented documents the process used for developing the synthesis and translation product, reports on efforts to engage the Prevention Support system to use the product, and how we approached building interaction between the Synthesis and Translation System and the Support System partners. Practice-oriented evaluation data are also presented. Implications for practice, policy and research are discussed.

    Influenza is a major health problem worldwide. Both seasonal influenza and pandemics take a major toll on the health and economy of our country. The present review focuses on the virology and complex immunology of this RNA virus in general and in relation to pregnancy. The goal is to attempt to explain the increased morbidity and mortality seen in infection during pregnancy. We discuss elements of innate and adaptive immunity as well as placental cellular responses to infection. In addition, we delineate findings in animal models as well as human disease. Increased knowledge of maternal and fetal immunologic responses to influenza is needed. However, enhanced understanding of nonimmune, pregnancy-specific factors influencing direct interaction of the virus with host cells is also important for the development of more effective prevention and treatment options in the future.

    Dogs have been studied for several reasons, such as the genetic improvement, their use as experimental models, in zoonotic research, cell therapy and as a model for human diseases. However, many features relating to the embryonic development of dogs remain unknown because of the absence of embryological studies. Considering the importance of the cardiorespiratory system in the development of embryos, the aim of this study was to investigate the development of the main cardiorespiratory organs of dog embryos and foetuses with estimated gestational ages from 16 to 46 days using macro- and microscopic descriptions. On day 16 of development, the neural tube and crest were formed, the anterior and posterior neuropore closure had begun and the somites had developed. Between days 22 and 27 of gestation, the lung buds and the initial formation of the primary bronchi and heart chambers were observed. The heart chambers exhibited the endo-, myo- and epicardial layers but did not have obvious differences in thickness among each other. Between days 41 and 46 of gestation, the nasal conchae and septa and trachea were formed, which exhibited characteristic epithelia. The lung formation and lobation were complete. The heart and major vessels exhibited mature histological architecture when their anatomical development was complete. The results of this study contribute to a more accurate definition of the embryonic and foetal developmental stages in dogs.

    Reproductive issues including contraception, fertility, and pregnancy are important components of the comprehensive care of women with systemic lupus erythematosus (SLE). SLE pregnancies are complicated due to risk for maternal disease exacerbation and potential for fetal and neonatal complications. Pre-pregnancy assessment is important to identify patients with severe disease-related damage who should avoid pregnancy, counsel patients to conceive when disease has been stable and inactive on appropriate medications, and assess relevant risk factors including renal disease, antiphospholipid antibody, and anti-Ro/SS-A and anti-La/SS-B antibodies. With careful planning, monitoring, and care, most women with SLE can anticipate a successful pregnancy.

    The impact of maternal systemic autoimmune diseases on pregnancy outcome is not unequivocally defined. We analysed the pregnancy outcome of 221 pregnancies from 181 autoimmune patients, consecutively followed in a single Italian reference centre from 2001 to 2009. All patients were prospectively followed with monthly visits. Pregnancy outcome was compared with the previous obstetrical history. The patient population comprised five groups: primary antiphospholipid syndrome (PAPS, 39 pregnancies), antiphospholipid syndrome associated with a rheumatic disease (APS/RD, 17 pregnancies), other RD (92 pregnancies), isolated autoantibodies (autoAbs) in the absence of a definite autoimmune disease (aAbs, 38 pregnancies) and reactive arthritis or spondyloarthropathies (35 pregnancies). Of these patients, 50.6% had previous pregnancy complications with an anamnestic live-birth rate of 43.4%. In these patients, complications dropped to 28.2% (44/156). This percentage was very similar to that observed in the 221 pregnancies (29.9%, 66/221) with a live-birth rate of 87.3%. Mean neonatal weight was 3018 ± 611 g; mean gestational age at delivery was 38.17 ± 2.79 weeks. Thus, 10.4% of pregnancies resulted in preterm delivery and 10.9% newborns had low weight at delivery. APS/RD patients had the worse outcome: 17.6% resulted in miscarriage, 14.3% resulted in growth restriction and 50% resulted in preterm delivery. This result was mainly due to patients with APS/systemic lupus erythematosus (SLE) that had the lowest gestational age at delivery (30.8 ± 3.56 weeks) and the lowest newborn weight (1499 ± 931 g). Results confirm that a strict follow-up and targeted treatments significantly improve pregnancy outcomes in autoimmune patients with PAPS, SLE and isolated autoAbs. The pregnancy outcome in patients with APS/SLE remains unsatisfactory.

    This review examines the risk factors for the development of systemic lupus erythematosus (SLE) flares during pregnancy. In preconception, anti-DNA, hypocomplementemia, previous thrombosis, triple antiphospholipid (aPL) antibody positivity, active lupus nephritis and discontinuation of medications such as hydroxychloroquine and azathioprine are factors associated with pregnancy failure. During pregnancy, SLE flares are associated with aPL antibodies, synergic changes of pregnancy on Th1 and TH2 cytokines, other cytokines and chemokines that interact with hormones such as estrogen and prolactin that amplify the inflammatory effect. From the clinical point of view, SLE activity at pregnancy onset, thrombocytopenia, lupus nephritis, arterial hypertension, aPL syndromes, preeclampsia is associated with lupus flares and fetal complications. In puerperium, the risk factors of flares are similar to pregnancy. Hyperactivity of immune system, autoantibodies, hyperprolactinemia, active lupus nephritis, decrease in TH2 cytokines with increase in TH1 cytokines probably participate in SLE flare. The SLE flares during pregnancy make the difference between an uncomplicated pregnancy and pregnancy with maternal and fetal complications. Therefore, the knowledge of risk factors leads the best treatment strategies to reduce flares and fetal complications in SLE patients.

    Systemic lupus erythematosus (SLE) is an autoantibody-mediated systemic autoimmune disease, predominantly affecting young females. Pregnancy is increasingly common in the setting of SLE, as survival and quality of life of patients improve. Although live births can be achieved in the most cases, pregnancy in patients with SLE remains a high-risk condition. Maternal and fetal mortality and morbidity are considerably increased, compared with the general population. Aberrations in pregnancy-related maternal immune adaptations are likely contributors. Active maternal disease, renal involvement, specific autoantibody subsets and advanced organ damage are predictors of poor outcome. Therapeutic options are limited during pregnancy as maternal benefit has to be weighed against fetal risk. Prevention of preterm birth and refractory pregnancy loss, as well as management of established neonatal heart block remain unmet needs. Further research should address these important issues that affect young patients with SLE and their babies.

  19. Vascular Complications of Systemic Sclerosis during Pregnancy

    2010-01-01

    Full Text Available Systemic sclerosis (SSc is a chronic autoimmune disorder characterized by progressive fibrosis of the skin and visceral tissues as well as a noninflammatory vasculopathy. Vascular disease in systemic sclerosis is a major cause of morbidity and mortality among nonpregnant patients with SSc and is even a bigger concern in the pregnant SSc patient, as the underlying vasculopathy may prevent the required hemodynamic changes necessary to support a growing pregnancy. Vascular manifestations including scleroderma renal crisis and pulmonary arterial hypertension should be considered relative contraindications against pregnancy due to the high associations of both maternal and fetal morbidity and mortality. In contrast, Raynaud's phenomenon may actually improve somewhat during pregnancy. Women with SSc who are considering a pregnancy or discover they are pregnant require evaluation for the presence and extent of underlying vasculopathy. In the absence of significant visceral vasculopathy, most women with SSc can expect to have reasonable pregnancy outcomes.

    Systemic lupus erythematosus (SLE) is a chronic, multisystem autoimmune disease that predominantly occurs in women of childbearing age. The risk of obstetric complications in lupus parturients is significant. In addition, pregnancy may be associated with flares of the disease requiring immunosuppressive therapy. For these reasons, SLE pregnancies are considered high risk and involve careful collaboration of the obstetrician and rheumatologist. Through the latter and medical advances including a better and better understanding of the binomial mother-child, most pregnancies end in a success.

    Systemic lupus erythematosus (SLE) is a disease of reproductive-age women, and thus questions regarding how disease influences pregnancy outcomes arise. We investigated whether five specific types of SLE activity during the 6 months before conception or during pregnancy (nephritis, cytopenias, skin disease, arthritis, serositis) were associated with adverse pregnancy outcomes. We performed a retrospective cohort study of pregnancy outcomes among women with SLE at the Brigham and Women's Hospital Lupus Center. Adverse pregnancy outcomes included pre-eclampsia, pre-term delivery, elective termination due to SLE, spontaneous miscarriage at weeks 12-20, and stillbirth. SLE and obstetric history, laboratories, and medications were obtained from electronic medical records. Generalized linear mixed models adjusting for potential confounders were used to identify predictors of any adverse pregnancy outcome. Most pregnancies resulted in a live term delivery (76.5 %). After adjustment for Hispanic ethnicity, prior adverse pregnancy outcome and medication use 6 months before conception, nephritis during pregnancy (odds ratio (OR) 3.6, 95 % confidence interval (CI) 1.0-12.8), cytopenias during pregnancy (OR 3.9, 95 % CI 1.3-11.4), and serositis during pregnancy (OR 5.9, 95 % CI 1.0-34.0) were significantly associated with adverse pregnancy outcome. Specific types of SLE disease activity during pregnancy were related to adverse pregnancy outcome. Nephritis, cytopenias, and serositis carried a higher risk of adverse pregnancy outcome, suggesting that these abnormalities should be carefully monitored during pregnancy.

    While fertility is preserved in females with systemic lupus erythematosus (SLE), it is well established that pregnancy in these patients is associated with adverse maternal and fetal outcomes, including pregnancy loss, pre-eclampsia, preterm delivery and intrauterine growth retardation, as well as neonatal mortality. Mechanisms underlying these adverse outcomes are poorly understood, and better understanding of these would allow development of targeted and personalized treatment strategies. Established risk factors for adverse pregnancy outcomes include active disease within 6 months prior to conception and during pregnancy, active nephritis, maternal hypertension, antiphospholipid antibodies and hypocomplementemia. While intensive monitoring is recommended, the comparative effectiveness of appropriate management strategies is unclear. While current strategies are able to achieve live births in 85-90% of pregnancies, certain aspects such as prevention of preterm birth, treatment of congenital heart block due to neonatal lupus and recurrent pregnancy loss despite best management, remains challenging. Pregnancy is also associated with an increased risk of flare of lupus, particularly in patients with active disease at time of conception or within 6 months prior to conception. Pregnant patients with SLE should be followed in a high-risk obstetric clinic, and care should be closely coordinated between the obstetrician and rheumatologist.

    Systemic sclerosis (SSc) is a connective tissue disease that usually affects women, with a male:female ratio of 1:4-10. It was thought that there was a prohibitive risk of fatal complications in the pregnancies of patients with SSc. It is now known that the majority of these women undergo a normal progression of pregnancy if the right time is chosen and a close obstetric care is delivered. The obstetric risk will depend on the subtype and clinical stage of the disease, and the presence and severity of the internal organ involvement during the pregnancy. The management of these pregnancies should be provided in a specialized center, with a multidisciplinary team capable of identifying and promptly treating complications. Treatment should be limited to drugs with no teratogenic potential, except when renal crises or severe cardiovascular complications develop. Copyright © 2014 Elsevier España, S.L.U.

    Women of childbearing age are at risk for developing systemic rheumatic diseases. Pregnancy can be challenging to manage in patients with rheumatic diseases for a variety of reasons including the impact of physiological and immunological changes of pregnancy on underlying disease activity, the varied presentation of rheumatic disease during pregnancy, and the limited treatment options. Previously, patients with rheumatic disease were often advised against pregnancy due to concerns of increased maternal and fetal morbidity and mortality. However, recent advancements in the understanding of the interaction between pregnancy and rheumatic disease have changed how we counsel patients. Patients with rheumatic disease can have successful pregnancy outcomes, particularly when a collaborative approach between the rheumatologist and obstetrician is applied. This review aims to discuss the effect of pregnancy on patients with the most common rheumatic diseases, the effect of these diseases on the pregnancy itself, and the management of these patients during pregnancy.

    Air pollution exposure has increased extensively in recent years and there is considerable evidence that exposure to particulate matter can lead to adverse respiratory outcomes. The health impacts of exposure to air pollution during the prenatal period is especially concerning as it can impair organogenesis and organ development, which can lead to long-term complications. Exposure to air pollution during pregnancy affects respiratory health in different ways. Lung development might be impaired by air pollution indirectly by causing lower birth weight, premature birth or disturbed development of the immune system. Exposure to air pollution during pregnancy has also been linked to decreased lung function in infancy and childhood, increased respiratory symptoms, and the development of childhood asthma. In addition, impaired lung development contributes to infant mortality. The mechanisms of how prenatal air pollution affects the lungs are not fully understood, but likely involve interplay of environmental and epigenetic effects. The current epidemiological evidence on the effect of air pollution during pregnancy on lung function and children's respiratory health is summarized in this review. While evidence for the adverse effects of prenatal air pollution on lung development and health continue to mount, rigorous actions must be taken to reduce air pollution exposure and thus long-term respiratory morbidity and mortality.

    2016-01-01

    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.

    Full Text Available 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.

    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%.

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.

    Full Text Available Systemic lupus erythematosus (SLE is a chronic inflammatory connective tissue disease commonly diagnosed after the age of 20, mostly around the age of 30 years. It is more common in women than in men, especially during the fertile period. Women with SLE are at higher risk for spontaneous abortions, intrauterine fetal death, preeclampsia and eclampsia, preterm delivery and intrauterine growth retardation. This paper is a case report of a pregnant woman with SLE complicated with preeclampsia, but it also discusses follow-up of such pregnancies.

    OBJECTIVE: The current study longitudinally evaluated concentrations of fibrinogen (Fib), D-Dimer, plasminogen activator type-1 (PAI-1) and tissue type plasminogen activator (T-Pa) before pregnancy and in the first and third trimesters of pregnancy with a focus on the pregnancy transition. STUDY DESIGN: Twenty healthy, nonsmoking, nulliparous women, aged 29.8 ± 3.0 years, BMI 23.3 ± 3.2 kg/m(2) were studied during menstrual cycle day 8 ± 4 and again in early (11 - 15 wks) and late (31 - 34 wks) pregnancy. Seventeen women had singleton conceptions and delivered at term with uncomplicated pregnancies (CTL) and three women developed complicated hypertension (CH) during pregnancy after the third trimester (late pregnancy) evaluation. Data are means ± SEM, Significance was based on p < 0.05. RESULTS: Fib was the only protein evaluated that increased in early pregnancy relative to the prepregnancy assessment. D-dimer, PAI-1 and T-Pa increased in the third trimester compared with prepregnant and early pregnant values (p < .001). T-PA was significantly higher during late pregnancy in CH subjects compared with CTL (8.1 ± 0.7 ng/ml vs. 5.0 ± 0.2 ng/ml, p = .02). There were no other differences between groups. CONCLUSIONS: Increases in fibrinogen are evident in early pregnancy whereas fibrinolysis, perhaps in response to the procoagulant environment of pregnancy, is increased during late pregnancy. Before development of clinically overt hypertension, T-Pa is increased without concomitant changes in other proteins assessed. This is consistent with altered endothelial function with preeclampsia that may contribute to, or reflect, the vasculopathy accompanying this disorder.

    Full Text Available Pregnancy in the setting of the uremic milieu of renal disease has a lower success rate than in the normal population and is a rare event. While intensified renal replacement therapy (RRT during pregnancy can lead to improved outcomes, most studies have focused on nocturnal hemodialysis as the main RRT in pregnancy. Although thousands of patients use the home NxStage System One short daily hemodialysis (SDHD machine in the United States, pregnancy outcomes with this therapy are unknown. The NxStage System One uses low-volume dialysate and hence small and middle molecule clearance may differ compared to conventional therapies and affect pregnancy outcomes. We report a case of a successful conception and pregnancy using the home NxStage system. The NxStage system may provide an alternative to the more routinely used NHD or standard SDHD therapies for women of childbearing age.

    Full Text Available Systemic Lupus Erythematosus (SLE predominantly afflicts young women in reproductive age. In this context, it is only rational that pregnancy and its outcome becomes an imperative concern for the lupus patients and their health care providers. Queries regarding the risk of disease flares during pregnancy, chance of fetal loss, and the safety of various drugs are often raised. However the present day availability of effective treatment regimens has meant that many patients achieve protracted remissions and better disease control. Indeed, a high proportion of lupus patients, with professional care, can thus look forward to a successful pregnancy.1 This article reviews the contemporary concepts regarding SLE and pregnancy, especially regarding the fertility rate, optimal timing of conception, risk of disease flares during lupus pregnancy, pregnancy course, fetal outcome, safety of various drugs used for disease control during pregnancy and lactation, and contraceptive advice.

    Gestational diabetes mellitus (GDM) contributes to the epidemic of diabetes and obesity in mothers and their offspring. The primary objective of this pilot study was to: 1) refine the GDM Management System (GooDMomS), a web-based pregnancy and postpartum behavioral intervention and 2) assess the feasibility of the intervention. In phase 1, ten semi-structured interviews were conducted with women experiencing current or recent GDM mellitus GDM to garner pilot data on the web based intervention interface, content, and to solicit recommendations from women about refinements to enhance the GooDMomS intervention site. Interviews were audiotaped, transcribed and independently reviewed to identify major themes with Atlas.ti v7.0. In phase 2, a single-arm feasibility study was conducted and 23 participants were enrolled in the GooDMomS program. Participants received web lessons, self-tracking of weight and glucose, automated feedback and access to a message board for peer support. The primary outcome was feasibility, including recruitment and retention and acceptability. Secondary outcomes included the proportion of women whose gestational weight gain (GWG) was within the Institute of Medicine (IOM) guidelines and who were able to return to their pre-pregnancy weight after delivery. Comments from semi-structured interviews focused on: 1) usability of the on-line self-monitoring diary and tracking system, 2) access to a safe, reliable social network for peer support and 3) ability of prenatal clinicians to access the on-line diary for clinical management. Overall, 21 (91 %) completed the pregnancy phase. 15/21 (71 %) of participants were within the Institute of Medicine (IOM) guidelines for GWG. Sixteen (70 %) completed the postpartum phase. 7/16 (43 %) and 9/16 (56 %) of participants returned to their pre-pregnancy weight at 6 and 30 weeks postpartum, respectively. This study documents the feasibility of the GooDMomS program. The results can have implications for web

    Systemic lupus erythematosus (SLE) has preponderance in women in their childbearing years; consequently pregnancy has always been an important issue of concern for the patient and the treating physician. Based upon numerous reports on successful pregnancy outcomes in the past decades, the initial advice against pregnancy in the 1950s has been replaced by a common understanding that women with SLE often have successful pregnancy outcomes, and clinicians therefore advise on pregnancy planning, including possible drug adjustments, timing and close surveillance. The recently published Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Antibody Syndrome and Systemic Lupus Erythematosus (PROMISSE) study, so far the largest multicentre cohort study of pregnant women with underlying stable SLE, has given some important answers to long-discussed questions. Future studies on data collected from the PROMISSE cohort will hopefully identify serological biomarkers, possibly genes, and in addition, give valuable information about underlying disease mechanisms. © The Author(s) 2016.

    Pregnancy in systemic lupus erythematosus patients is a common situation that remains associated with higher maternal and fetal mortality/morbidity than in the general population. Complications include lupus flares, obstetrical complications (fetal loss, in utero growth retardation, prematurity) and neonatal lupus syndrome. The association with antiphospholipid antibodies or antiphospholipid syndrome increases the risk of obstetrical complications. Improving the care of these pregnancies depends upon a systematic pregnancy planning, ideally during a preconception counseling visit and a multidisciplinary approach (internist/rheumatologist, obstetrician and anesthetist). The absence of lupus activity, the use of appropriate medications during pregnancy adjusted to the patient's medical history and risk factors, and a regular monitoring are the best tools for a favorable outcome for these high-risk pregnancies. The aim of this review article is to perform an update on the medical care of pregnancy in systemic lupus erythematosus or antiphospholipid syndrome to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

    Few studies have been published focusing on the clinical features of new-onset systemic lupus erythematosus (SLE) during pregnancy. This study examined the clinical characteristics of SLE during pregnancy or puerperium. The clinical characteristics and serological parameters of 48 patients with onset of SLE during pregnancy were retrospectively compared with those of age-matched new-onset SLE patients who were diagnosed in a period of more than 12 months without pregnancy (n = 65) and age-matched preeclampsia patients (n = 48). SLE tended to occur during the first and second trimesters (33 and 42 %, respectively). Lupus nephritis (LN) and severe thrombocytopenia were more commonly seen in new-onset SLE during pregnancy than in patients without pregnancy (68.8 vs 35.4 % and 25 vs 9.2 %, respectively, p pregnancy (n = 23), LN patients with pregnancy (n = 33) had more prominent proteinuria and nephrotic syndrome (p pregnancy had early onset of symptoms during gestation and were characterized by presence of fever, malar lesion, autoantibodies, hypocomplementemia, hyperuricemia, active urinary sediment, and multi-organ involvement. In conclusion, patients with their first onset of lupus during pregnancy generally have more severe disease with higher prevalence of renal and platelet involvement.

    Systemic lupus erythematosus (SLE) is an autoimmune disease caused by the interaction between genetic and environment factors which leads to abnormal immune responses. SLE affects more commonly women of childbearing age which raises the following questions--the influence of the disease activity on pregnancy and the influence of pregnancy on disease activity. On the one hand physiological changes occurring during pregnancy could lead to increased SLE activity, on the other hand the latter could mimic SLE activity. Differentiating these manifestations is important for the clinical practice--pregnancy and delivering guidance and SLE therapy.

    Ectopic pregnancy is a frequent early complication of pregnancy associated with significant rates of morbidly and mortality. The positive diagnosis of this condition is established through transvaginal ultrasound scanning. The timing of diagnosis depends on the operator expertise in identifying the signs of ectopic pregnancy, which varies dramatically among medical staff with heterogeneous training. Developing decision support systems in this context is expected to improve the identification of these signs and subsequently improve the quality of care. In this article, we present a new knowledge base for ectopic pregnancy, and we demonstrate its use on the annotation of clinical images. The knowledge base is supported by an application ontology, which provides the taxonomy, the vocabulary and definitions for 24 types and 81 signs of ectopic pregnancy, 484 anatomical structures and 32 technical elements for image acquisition. The knowledge base provides a sign-centric model of the domain, with the relations of signs to ectopic pregnancy types, anatomical structures and the technical elements. The evaluation of the ontology and knowledge base demonstrated a positive feedback from a panel of 17 medical users. Leveraging these semantic resources, we developed an application for the annotation of ultrasound images. Using this application, 6 operators achieved a precision of 0.83 for the identification of signs in 208 ultrasound images corresponding to 35 clinical cases of ectopic pregnancy. We developed a new ectopic pregnancy knowledge base for the annotation of ultrasound images. The use of this knowledge base for the annotation of ultrasound images of ectopic pregnancy showed promising results from the perspective of clinical decision support system development. Other gynecological disorders and fetal anomalies may benefit from our approach.

    Full Text Available Yuriko Yamamoto, Shigeru Aoki Perinatal Center for Maternity and Neonate, Yokohama City University Medical Center, Yokohama, Kanagawa Prefecture, Japan Abstract: 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.

  8. Maternal enrichment during pregnancy accelerates retinal development of the fetus.

    Full Text Available The influence of maternal environment on fetal development is largely unexplored, the available evidence concerns only the deleterious effects elicited by prenatal stress. Here we investigated the influence of prenatal enrichment on the early development of the visual system in the fetus. We studied the anatomical development of the rat retina, by analyzing the migration of neural progenitors and the process of retinal ganglion cell death, which exerts a key role in sculpturing the developing retinal system at perinatal ages. The number of apoptotic cells in the retinal ganglion cell layer was analyzed using two distinct methods: the presence of pyknotic nuclei stained for cresyl violet and the appearance of DNA fragmentation (Tunel method. We report that environmental enrichment of the mother during pregnancy affects the structural maturation of the retina, accelerating the migration of neural progenitors and the dynamics of natural cell death. These effects seem to be under the control of insulin-like growth factor-I: its levels, higher in enriched pregnant rats and in their milk, are increased also in their offspring, its neutralization abolishes the action of maternal enrichment on retinal development and chronic insulin-like growth factor-I injection to standard-reared females mimics the effects of enrichment in the fetuses. Thus, the development of the visual system is sensitive to environmental stimulation during prenatal life. These findings could have a bearing in orienting clinical research in the field of prenatal therapy.

    Previous reports indicate that maternal and fetal outcome in pregnancies complicated by systemic lupus erythematosus (SLE) may be strongly influenced by the presence of renal disease. As the relationship between renal histology and clinical function in SLE is not consistent, prospective data on the outcomes of such pregnancies would aid patient counselling. Fifteen women with SLE had 18 pregnancies subsequent to renal biopsies, performed from 3 months to 8 years prior to conception. Their renal function was evaluated before, during and after pregnancy. Fourteen of 15 patients had evidence of renal involvement, based on by light and electron microscopic sections: 7 had mesangial involvement (WHO Class II); 5 had active focal or diffuse glomerulonephritis (Classes III and IV); two had membranous involvement (Class V); 1, no evident disease. Perinatal outcome was similar whether lesions were milder (8 continuing pregnancies, 4 term deliveries) or more severe (6 continuing pregnancies, 3 term deliveries). Clinical renal function was normal in all but 3 cases at the beginning of pregnancy; 2 additional patients experienced moderate deteriorations in renal function during pregnancy but recovered normal function in the puerperium. Fetal outcome was abnormal (3 premature deliveries, 1 neonatal death, 1 spontaneous abortion) in all cases where renal function was decreased, while 10 of 13 pregnancies in patients with normal renal function ended in term deliveries. The data suggest that currently preconceptual renal histology provides a less accurate basis for perinatal counselling than does the assessment of clinical renal function.

    Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disorder that predominantly affects women of reproductive age. As clinical outcomes improve, pregnancy in these women is becoming more common. Although epidemiological data have documented an improvement in the prognosis of pregnancy in these women over recent years, they are still at significantly increased risk of pregnancy complications, such as miscarriage, stillbirth, pre-eclampsia and impaired foetal growth. The pathogenesis of SLE involves marked immune dysfunction, and in particular, the function of immunosuppressive elements of the immune system is impaired, including regulatory T-cell function. Because regulatory T cells are likely to be the key cell-modulating feto-maternal tolerance, this review overviews the possibility that regulatory T-cell impairments contribute to pregnancy pathology in women with SLE and contribute to the clinical challenge of managing these women during pregnancy.

    Pregnancy in women diagnosed with systemic sclerosis generally has a favorable outcome according to most recent studies. Women with systemic sclerosis who wish to become pregnant should achieve low disease activity for at least 6 months prior to conception. Regular follow-up of pregnant scleroderma patients by an interdisciplinary medical team including gynaecologists and rheumatologists is necessary to control disease activity and avoid possible complications. Severe organ involvement, early diffuse systemic sclerosis with rapid onset, and pulmonary hypertension ought to discourage patients from pregnancy, as these situations are at high risk of complications for both mother and fetus during pregnancy.

    Systemic autoimmune diseases especially affect young women during childbearing age. The aim of this review is to update systemic lupus erythematosus, antiphospholipid syndrome and systemic sclerosis management during pregnancy. These diseases present variable maternal and fetal risks. Studies show that an appropriate disease control and a reasonable remission period prior to pregnancy are associated with satisfactory obstetric outcomes. Antiphospholipid autoantibodies profile, anti-Ro/anti-La antibodies, pulmonary pressure and activity evaluation are crucial to assess the pregnancy risk. Monitoring requires a multidisciplinary team, serial analytic controls and Doppler ultrasound of maternal and fetal circulation. Evaluation of the activity of the disease is essential.

    2011-01-01

    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.

    A causal link has long been described between estrogen and systemic lupus erythematosus activity. Contraceptive and pregnancy management is now common for lupus patients, but pregnancy continues to be associated with higher maternal and fetal mortality/morbidity in systemic lupus erythematosus patients than among the general population. Potential complications include lupus flares, obstetric complications (fetal loss, in utero growth retardation, premature birth) and neonatal lupus syndrome. Association with antiphospholipid antibodies or antiphospholipid syndrome increases the risk of obstetric complications. Anti-SSA and/or anti-SSB antibodies put fetuses at risk for neonatal lupus. Improving the outcome of such pregnancies depends upon optimal systematic planning of pregnancy at a preconception counseling visit coupled with a multidisciplinary approach. Absence of lupus activity, use of appropriate medication during pregnancy based on the patient's medical history and risk factors, and regular monitoring constitute the best tools for achieving a favorable outcome in such high-risk pregnancies. The aim of this review is to provide an update on the management of contraception and pregnancy in systemic lupus erythematosus, cutaneous lupus and/or antiphospholipid syndrome in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

    Full Text Available Systemic lupus erythematosus (SLE is a multisystem disease. This study was under-taken to assess the outcome of pregnancies in patients with inactive SLE. We prospectively studied 20 female patients with diagnosis of stable class IV Lupus nephritis followed up at King Abdul Aziz University Hospital, in Jeddah, Saudi Arabia between 1998 and 2008. Before each pregnancy all the patients had their blood pressure, serum creatinine, creatinine clearance, serology for SLE and 24-hour urine protein excretion measured and then repeated at monthly intervals during the pregnancy. Statistical analysis was performed using the Wilcoxon signed-rank test. Despite having negative antinuclear antibody (ANA significant complications were observed during pregnancy. The daily proteinuria during 34-36 weeks′ gestation was significantly higher (P< 0.05 than during 32 weeks. Two patients had abortions one stillbirth and 2 required termination of the pregnancy; one due to severe hypertension, and other due to renal impairment. One patient developed HELLP (hemolysis, elevated liver enzymes, low platelets syndrome. 14 patients had a successful preg-nancy, including 4 requiring a cesarian section. In conclusion, although no clinical evidence of lupus disease activity was demonstrated pre-conception proteinuria significantly increased during pregnancy along with maternal and fetal complications. Pregnant females with diagnosis of SLE need a multidisciplinary care during the pregnancy and post-partum period.

    Systemic lupus erythematosus (SLE) is a chronic, multisystem autoimmune disease predominantly affecting women, particularly those of childbearing age. SLE provides challenges in the prepregnancy, antenatal, intrapartum, and postpartum periods for these women, and for the medical, obstetric, and midwifery teams who provide their care. As with many medical conditions in pregnancy, the best maternal and fetal-neonatal outcomes are obtained with a planned pregnancy and a cohesive multidisciplinary approach. Effective prepregnancy risk assessment and counseling includes exploration of factors for poor pregnancy outcome, discussion of risks, and appropriate planning for pregnancy, with consideration of discussion of relative contraindications to pregnancy. In pregnancy, early referral for hospital-coordinated care, involvement of obstetricians and rheumatologists (and other specialists as required), an individual management plan, regular reviews, and early recognition of flares and complications are all important. Women are at risk of lupus flares, worsening renal impairment, onset of or worsening hypertension, preeclampsia, and/or venous thromboembolism, and miscarriage, intrauterine growth restriction, preterm delivery, and/or neonatal lupus syndrome (congenital heart block or neonatal lupus erythematosus). A cesarean section may be required in certain obstetric contexts (such as urgent preterm delivery for maternal and/or fetal well-being), but vaginal birth should be the aim for the majority of women. Postnatally, an ongoing individual management plan remains important, with neonatal management where necessary and rheumatology followup. This article explores the challenges at each stage of pregnancy, discusses the effect of SLE on pregnancy and vice versa, and reviews antirheumatic medications with the latest guidance about their use and safety in pregnancy. Such information is required to effectively and safely manage each stage of pregnancy in women with SLE.

    The most common treatment modalities of ectopic pregnancy may influence long-term subsequent fertility outcomes in women who previously treated for ectopic pregnancy. Our objective was to compare long-term subsequent fertility outcomes after treatment with expectant management, systemic methotrexate (MTX) and surgery in tubal ectopic pregnancy. We searched our database for all women diagnosed with tubal ectopic pregnancy between January 2007 and January 2011 who were managed expectantly, with systemic MTX and with surgery. Treatment success and spontaneous pregnancy rates were compared in patients who desire to conceive following a tubal pregnancy. One hundred twelve of 151 women desired to conceive following tubal ectopic pregnancy. Twenty-seven of 112 (24.1 %) patients were managed expectantly. Fifty-three (47.3 %) and 32 (28.5 %) patients were managed with systemic MTX or surgery, respectively. All patients in expectant and surgery groups were managed successfully. Two (3.7 %) patients had surgery after failed treatment with systemic MTX. Spontaneous intrauterine pregnancy rates were 62.9 % in expectantly managed women, 58.4 % in women with systemic MTX and 68.7 % in women with surgery (p > 0.05). Treatment of ectopic pregnancy with either expectant management or systemic MTX is equally effective as compared to surgery. Spontaneous intrauterine pregnancy rates were comparable in expectant management, systemic methotrexate and surgery.

    During mammalian pregnancy, highly specialized mechanisms of immune tolerance are triggered in order to allow the semi-allogeneic fetus to grow within the maternal uterus in harmony with the maternal immune system. Among other mechanisms, changes in the endocrine status have been proposed to be at least part of the machinery responsible for the induction of immune tolerance during pregnancy. Indeed, pregnancy-associated hormones, estradiol, progesterone, and human chorionic gonadotropin are known to confer immune suppressive capacity to innate as well as adaptive immune cells. Regulatory B cells, a subpopulation of B lymphocytes with strong immunosuppressive functions, were shown to expand during pregnancy. Furthermore, it is well-known that some women suffering from multiple sclerosis, significantly improve their symptoms during pregnancy and this was attributed to the effect of female sex hormones. Accordingly, estradiol protects mice from developing experimental autoimmune encephalomyelitis by triggering the expansion and activation of regulatory B cells. In this review, we discuss different mechanisms associated with the development, activation, and function of regulatory B cells with a special focus on those involving pregnancy-associated hormones.

    Full Text Available Objective: To evaluate the outcome of 80 pregnant women with systemic lupus erythematosus (SLE and explore the risk factors for lupus flare, obstetric complications and fetal loss. Methods: 83 pregnancies in 80 women were divided into three groups. Group A: patients in remission for > 6 months before pregnancy, proteinuria < 0.5 g per day, without renal failure and discontinuation of cytotoxic drugs for > one year; Group B: patients with SLE disease activity in the six months before pregnancy; Group C: patients with new onset SLE during pregnancy. Results: In group A, 76.47% pregnancies achieved full-term deliveries and 80.39% achieved live born infants. In group B and C, the outcome was poor. Among 62 patients (64 pregnancies diagnosed as SLE before pregnancy, SLE flares occurred in 27 (42.19% pregnancies. SLE disease activity in the six months before pregnancy was significantly associated with lupus flare (OR 5.00, 95% CI 1.14–21.87, p = 0.03 and fetal loss. New onset lupus during pregnancy was independently associated with obstetric complications (OR 7.22, 95% CI 2.14–24.38, p = 0.001. Conclusions: The current study confirmed the previous report that SLE should be considered a high risk of pregnancy. If pregnancy is planned after remission for > 6 months, the favorable outcome can be achieved.

    Full Text Available Normal pregnancy is an immunotolerant state. Many factors, including environmental, socioeconomic, genetic, and immunologic changes by infection and/or other causes of inflammation, may contribute to inter-individual differences resulting in a normal or pathologic pregnancy. In particular, imbalances in the immune system can cause many pregnancy-related diseases, such as infertility, abortions, pre-eclampsia, and preterm labor, which result in maternal/fetal death, prematurity, or small-for-gestational age newborns. New findings imply that myeloid regulatory cells and regulatory T cells (Tregs may mediate immunotolerance during normal pregnancy. Effector T cells (Teffs have, in contrast, been implicated to cause adverse pregnancy outcomes. Furthermore, feto-maternal tolerance affects the developing fetus. It has been shown that the Treg/Teff balance affects litter size and adoptive transfer of pregnancy-induced Tregs can prevent fetal rejection in the mouse. Heme oxygenase-1 (HO-1 has a protective role in many conditions through its anti-inflammatory, anti-apoptotic, antioxidative, and anti-proliferative actions. HO-1 is highly expressed in the placenta and plays a role in angiogenesis and placental vascular development and in regulating vascular tone in pregnancy. In addition, HO-1 is a major regulator of immune homeostasis by mediating crosstalk between innate and adaptive immune systems. Moreover, HO-1 can inhibit inflammation-induced phenotypic maturation of immune effector cells and pro-inflammatory cytokine secretion and promote anti-inflammatory cytokine production. HO-1 may also be associated with T-cell activation and can limit immune-based tissue injury by promoting Treg suppression of effector responses. Thus, HO-1 and its byproducts may protect against pregnancy complications by its immunomodulatory effects, and the regulation of HO-1 or its downstream effects has the potential to prevent or treat pregnancy complications and

    Progressive moyamoya disease in pregnancy and puerperium has not been reported previously. Here, we present a 39-year-old woman who had been found to have moderate stenosis of right middle cerebral artery (MCA) 4 years prior to her pregnancy, finally suffering minor completed stroke due to progressive moyamoya disease at the early postpartum period. Three days after cesarean section without any complication, she developed cerebral infraction at right hemisphere, when magnetic resonance angiography indicated apparent progression of the proximal MCA stenosis. Catheter angiography demonstrated nearly occlusion of the right terminal internal carotid artery (ICA) and the development of an abnormal vascular network at the base of the brain as well as MCA stenosis, indicating a definitive diagnosis of moyamoya disease with unilateral involvement. The patient underwent superficial temporal artery-middle cerebral artery anastomosis 1 month after the onset of stroke, and she did not manifest as further neurological events during the follow-up period of 2 years. Moyamoya disease could newly develop in pregnancy and puerperium, which should be noted as a pitfall of the management of moyamoya disease with pregnancy.

    We report a case of systemic lupus erythematosus (SLE) in a young woman who became pregnant amid a severe flare. She continued to have active disease in the face of aggressive treatments complicated by several side effects of immunosuppressive drugs including recurrent sepsis and gestational diabetes. Her fetus was at risk for congenital heart block during the second and third trimesters. Despite an extremely guarded prognosis, she delivered a healthy baby girl. This case highlights the complexities of SLE management during pregnancy. We discuss the therapeutic options available in pregnancy, and highlight the importance of cross-specialty multidisciplinary care in these women.

    We present a case which describes a 29-year-old woman with systemic lupus erythematosus who was treated aggressively with cytotoxic immunosuppression. Five years later and approximately 12 weeks pregnant, she is confirmed as having carcinoma of the tongue. Not wishing to consider termination of her pregnancy, she underwent surgical resection, which included partial glossectomy with microvascular reconstruction. Good oral function (speech and swallowing) was restored within 2 weeks. The pregnancy proceeded relatively uneventfully to 37 weeks gestation when proteinuric hypertension necessitated induction of labour. She remains well with no evidence of recurrence. This case highlights the options available in the treatment of carcinoma of the tongue during pregnancy together with the ethical considerations required, balanced against optimising maternal outcomes.

The large population-based data set of the Hungarian Case‑Control Surveillance of Congenital Abnormalities (HCCSCA was evaluated based on the medically recorded infusion treatment during pregnancy. Of 22,843 case pregnant women who had newborns or fetuses with congenital abnormalities, 112 (0.5%, while of 38,151 control pregnant women who had newborn infants without any defects, 262 (0.7%, had infusion treatment during pregnancy. Infusion treatment was more frequent in the control group than in the case group with congenital abnormalities (adjusted POR with 945 95% CI: 0.7, 0.6-0.9 and there was no higher rate of maternal infusion treatments in any congenital abnormality group. Mean gestational age was shorter and mean birth weight was smaller in control newborn infants without CA born to mothers with infusion treatment during pregnancy than in the babies of mothers without infusion treatment. The prevalence of mild intrauterine growth retardation was more frequent in the fetuses of pregnant women with hyperemesis gravidarum treated with infusion. The results of the study suggest that infusion treatment of pregnant women did not associate with a higher risk of congenital abnormalities. In addition, the intravenous infusion of drugs has some, but limited efficacy to prevent the adverse effects of hyperemesis gravidarum and threatened preterm delivery.

    Multidisciplinary approach and patient counselling have been the key points in the improvement of the management of pregnancy in women with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). Most of these women can have successful pregnancy when thoroughly informed and instructed on several different issues. Disease activity should be in stable remission prior to pregnancy in order to reduce the chance for flare during pregnancy. To this purpose, medications must be modulated: "safe" drugs should be continued throughout pregnancy, embryotoxic/foetotoxic drugs should be withdrawn timely, and beneficial drugs such as low dose aspirin and heparin should be added for prophylaxis of maternal and foetal outcome, especially in the presence of antiphospholipid antibodies. The safety profile of anti-rheumatic drugs during pregnancy and breastfeeding should be kept constantly updated, as new data from inadvertent exposure accumulates and new drugs (especially biological agents) are available. Patients may carry autoantibodies that can negatively affect the baby, being neonatal lupus the prototypical case of passively acquired autoimmunity. Research has been greatly active in this field and more information on risk stratification and management are now available for counselling. The effect of both autoantibodies and drug exposure has been evaluated in the offspring: some concerns about learning disabilities have been raised, but these are treatable conditions that are likely to be overcome. To counsel a woman with SLE/APS during childbearing age means also to deal with contraception. Despite the "preferred choice" - combined oral contraceptive - may not be suitable for most of the patients, other options are available and should be offered and discussed with the patient. Fertility is not generally affected in SLE/APS patients, but those cases who require assisted reproduction techniques should be carefully evaluated and managed.

    Full Text Available Unintended pregnancy is among the most troubling public health problems and a major reproductive health issue worldwide imposing appreciable socioeconomic burden on individuals and society. Governments generally plan to control growth of births (especially wanted births as well as orphans and illegitimate births imposing extra burden on public funding of the governments which inevitably affects economic efficiency and leads to economic slowdown, too. The present narrative review focuses on socioeconomic impacts of unintended pregnancy from the health system perspective. Follow of Computerized searches of Academic, 53 scientific journals were found in various databases including PubMed, EMBASE, ISI, Iranian databases, IPPE, UNFPA (1985-2013. Original articles, review articles, published books about the purpose of the paper were used. During this search, 20 studies were found which met the inclusion criteria. Unintended pregnancy is one of the most critical challenges facing the public health system that imposes substantial financial and social costs on society. On the other hand, affecting fertility indicators, it causes reduced quality of life and workforce efficiency. Therefore lowering the incidence of intended pregnancies correlates with elevating economic growth, socio-economic development and promoting public health. Regarding recent policy changes in Iran on family planning programs and adopting a new approach in increasing population may place the country at a higher risk of increasing the rate of unintended pregnancy. Hence, all governmental plans and initiatives of public policy must be regulated intelligently and logically aiming to make saving in public spending and reduce healthcare cost inflation.

  1. The Use of Central Nervous System Active Drugs During Pregnancy

    Directory of Open Access Journals (Sweden)

    Bengt Källén

    2013-10-01

    Full Text Available CNS-active drugs are used relatively often during pregnancy. Use during early pregnancy may increase the risk of a congenital malformation; use during the later part of pregnancy may be associated with preterm birth, intrauterine growth disturbances and neonatal morbidity. There is also a possibility that drug exposure can affect brain development with long-term neuropsychological harm as a result. This paper summarizes the literature on such drugs used during pregnancy: opioids, anticonvulsants, drugs used for Parkinson’s disease, neuroleptics, sedatives and hypnotics, antidepressants, psychostimulants, and some other CNS-active drugs. In addition to an overview of the literature, data from the Swedish Medical Birth Register (1996–2011 are presented. The exposure data are either based on midwife interviews towards the end of the first trimester or on linkage with a prescribed drug register. An association between malformations and maternal use of anticonvulsants and notably valproic acid is well known from the literature and also demonstrated in the present study. Some other associations between drug exposure and outcome were found.

    Adaptive physiological changes that occur in pregnant women can fluctuate with the intake of substances with proven, adverse biological effect on the body. Due to the fact that caffeine is one of the most chronically used xenobiotics, the impact of consuming caffeine on adaptive processes in the circulatory system of a pregnant women required a research. Many researchers emphasise its negative effect on the circulatory system of the mother and her offspring. However, in spite of years of observation, there is no clear answer to what extent dose or in what period of time the caffeine modulates the adaptive processes during pregnancy. Because of the potential risk the supply of caffeine during pregnancy should be subjected to considerable restrictions.

    Since 1979, the CDC Pregnancy Nutrition Surveillance System (PNSS) has monitored behavior and nutritional risk factors among low-income pregnant women participating in public health programs. Although the states contributing to the system have varied over the period, the PNSS is able to characterize the behavior and health outcomes of pregnant women from diverse low-income populations. In 1990, 66.2% of the women in the system initiated prenatal care during the first trimester of pregnancy; 26.4% smoked during pregnancy. Since 1979, the prevalence of smoking remained relatively stable for white women, but declined for blacks and Hispanics. Prepregnancy body mass index (BMI, defined as kg/m2) showed marked changes from 1979 through 1990; the prevalence of underweight (BMI 26) increased steadily. In 1990, 39.3% of the women had gestational weight gains below levels recommended by the National Academy of Sciences. Both prepregnancy underweight and inadequate gestational weight gain were associated with greater risk for low birth weight in the PNSS. The prevalence of anemia at each trimester has remained stable since 1979. In 1990, 9.8%, 13.8%, and 33% of the women reported by the PNSS were anemic in the first, second, and third trimesters, respectively. Anemia in the first trimester appeared to be strongly associated with a high risk of low birth weight; this association was attenuated in later trimesters. These findings indicate the need to improve iron nutrition among low-income women.

EDCs may affect thyroid hormone homeostasis by different mechanisms, and though the effect of each chemical seems scarce, the added effects may cause inappropriate consequences on, for example, foetal...... neurodevelopment. This paper focuses on thyroid hormone influence on foetal development in relation to the chemicals suspected of thyroid disrupting properties with possible interactions with maternal thyroid homeostasis. Knowledge of the effects is expected to impact the general debate on the use...

    Pregnancy in patients suffering from undifferentiated connective tissue disease (UCTD) represents a risk situation for both the mother and the child. SSA/SSB autoantibodies can determine neonatal lupus (NL) in the foetus, regardless of the maternal disease. Furthermore, pregnancy increases the risk of flares and evolution to differentiated connective tissue disease (CTD). We report an uncommon case in which these complications occurred in a mother and in her foetuses. A 37-year-old woman affected by UCTD developed systemic lupus erythematosus (SLE) after her triplet pregnancy. The only manifestation of neonatal lupus we observed in the three newborns was SSA positivity associated with asymptomatic transient neutropenia.

    Manipulations in metabolic parameters during pregnancy/lactation can impact the development of short- and long-term energy control mechanisms, which are mainly modulated by neural and hormonal inputs to the hypothalamus. Thus, we tested how mice training and detraining during pregnancy and lactation affect hypothalamus gene expression and change biometric and metabolic profiles of the offspring. Three-month-old female Swiss mice were submitted to an 8-week exercise program (swimming 5 times/week, 1 h/day). Following this physical exercise protocol, these conditioned animals and the control group were submitted to matting. After pregnancy verification, the animals were distributed into four groups: training during pregnancy and lactation (T); detraining after pregnancy confirmation (DP); detraining during lactation (DL); and control (CT), without interventions. After weaning, the offspring of the four groups were derived into these as follows: TO, DPO, DLO, and CTO, respectively. The body weight was lower in conditioned females compared to control at weeks 4-8 of the exercise regimen. No statistical difference in dam's body weight was observed during pregnancy. Related to offspring, at post-natal day 90, the animals were euthanized and DPO and DLO showed decrease in Npy and Cart expression in hypothalamus, and DLO also had increased Lep gene expression in white adipose tissue. Additionally, DPO showed increase in plasma triglycerides levels, total liver weight, and decrease in brown adipose tissue compared to CTO. Together, these results support that detraining during critical periods of development leads to altered gene expression in hypothalamic neuropeptidergic systems.

  10. Adolescent pregnancy: combating the problem from a multi-systemic health perspective.

    Presented is a multi-systemic theoretical model of adolescent pregnancy that incorporates the school-peer-family-community systems and defines a role for health educators. It is noted that teenagers receive conflicting messages from the adolescent socialization community--all the institutions, individuals, and mass media that influence and shape development. To cope with these multiple, inconsistent messages, many adolescents respond with inconsistent behavior given the impossibility of pleasing all sources of influence. Health educators must coordinate the school-peer-family-community systems to achieve more congruence and less competition surrounding inputs into the daily life of young people. The potential to disseminate sex education is greatest in the school context, where information can be provided on a systematic, regular basis to reinforce learning. Since peers are a major reference group during adolescence, per counseling can be used effectively to discuss factors that lead to unwanted pregnancy and help clarify values. Sex education programs are strengthened by the involvement of parents, and interventions aimed at promoting parent-child communication around sexual issues have been demonstrated to delay the onset of sexual activity. The availability of an adolescent health clinic, either in the school or close by, has been shown to reduce adolescent pregnancy. Overall, the most effective adolescent pregnancy prevention programs are those that are comprehensive in substance and duration.

    We investigated the clinical and laboratory characteristics of pregnancies with systemic lupus erythematosus (SLE) and identified lupus flare predictors during pregnancy. Additionally, we examined lupus activity and pregnancy outcomes in SLE patients who continued, discontinued or underwent no hydroxychloroquine (HCQ) treatment during pregnancy. We retrospectively analyzed 179 pregnancies in 128 SLE patients at Seoul St. Mary's Hospital, Korea, between 1998 and 2012 and then assessed the clinical profiles and maternal and fetal outcomes. Overall, 90.5% of pregnancies resulted in a successful delivery and were divided into two groups: those who experienced lupus flares (80 pregnancies, 44.7%) and those who did not (99 pregnancies, 55.3%). Increased preeclampsia, preterm births, low birth weight, intrauterine growth restriction (IUGR), and low 1-minute Apgar scores occurred in pregnancies with lupus flares compared to pregnancies in quiescent disease. Lupus flares were predicted by HCQ discontinuation, a history of lupus nephritis, high pre-pregnancy serum uric acid and low C4 levels. Our study indicates that achieving pre-pregnancy remission and continuing HCQ treatment during pregnancy are important for preventing lupus flares.

    Thyroid abnormalities are common during pregnancy and can affect pregnancy outcome. In 2012, the working group for endocrinology was assigned by SFOG to develop evidence based guidelines for their management. There is high quality evidence that untreated clinical hypothyroidism increases the risk of pregnancy and fetal complications. Subclinical hypothyroidism is associated with pregnancy complications. The presence of TPO-antibodies is linked to miscarriage and premature birth. It is uncertain whether subclinical hypothyroidism/maternal TPO-antibodies adversely affect the child's neurocognitive development. Reference intervals for TSH among pregnant women in Sweden need to be established.

    Periconception supplementation with folic acid is recommended until 12 gestational weeks to prevent neural tube defects. Doses of folic acid contained in supplements and timing and length of use during pregnancy vary. The effects of status in periconception and pregnancy folate, cobalamin, betaine and their interactions on one carbon metabolism (1C), as well as the global effect of 1C on foetal growth and pregnancy outcome, are reviewed. Results from prospective studies are reviewed. Cessation of folic acid supplement use after the first trimester is associated with a sharp drop in plasma folate status and enhanced conversion of betaine to dimethylglycine. Dimethylglycine production is also higher in mothers with low folate status than in those with normal-high folate status. The effects of high doses of folic acid on one carbon metabolism in mothers with low early pregnancy cobalamin status and on foetal growth are also reviewed. Several studies report that moderately elevated early pregnancy fasting plasma total homocysteine (tHcy) is inversely associated with birth weight and a predictor of intrauterine growth retardation. There is also evidence for increased risk of preterm birth when maternal folate status is low.

    During mammalian pregnancy, highly specialized mechanisms of immune tolerance are triggered in order to allow the semi-allogeneic fetus to grow within the maternal uterus in harmony with the maternal immune system. Among other mechanisms, changes in the endocrine status have been proposed to be at least part of the machinery responsible for the induction of immune tolerance during pregnancy. Indeed, pregnancy-associated hormones, estradiol, progesterone and human chorionic gonadotropin are kn...

  16. Sexually dimorphic adaptations in basal maternal stress physiology during pregnancy and implications for fetal development.

    2015-06-01

    There is clear evidence of reciprocal exchange of information between the mother and fetus during pregnancy but the majority of research in this area has focussed on the fetus as a recipient of signals from the mother. Specifically, physiological signals produced by the maternal stress systems in response to the environment may carry valuable information about the state of the external world. Prenatal stress produces sex-specific adaptations within fetal physiology that have pervasive and long-lasting effects on development. Little is known, however, about the effects of sex-specific fetal signals on maternal adaptations to pregnancy. The current prospective study examined sexually dimorphic adaptations within maternal stress physiology, including the hypothalamic-adrenal-pituitary (HPA) axis and the autonomic nervous system (ANS) and associations with fetal growth. Using diurnal suites of saliva collected in early and late pregnancy, we demonstrate that basal cortisol and salivary alpha-amylase (sAA) differ by fetal sex. Women carrying female fetuses displayed greater autonomic arousal and flatter (but more elevated) diurnal cortisol patterns compared to women carrying males. Women with flatter daytime cortisol trajectories and more blunted sAA awakening responses also had infants with lower birth weight. These maternal adaptations are consistent with sexually dimorphic fetal developmental/evolutionary adaptation strategies that favor growth for males and conservation of resources for females. The findings provide new evidence to suggest that the fetus contributes to maternal HPA axis and ANS regulation during pregnancy and that these systems also contribute to the regulation of fetal growth.

    Full Text Available Pregnancy induces drastic biological changes systemically, and has a beneficial effect on some autoimmune conditions such as rheumatoid arthritis (RA. However, specific systemic changes that occur as a result of pregnancy have not been thoroughly examined in healthy women or women with RA. The goal of this study was to identify genes with expression patterns associated with pregnancy, compared to pre-pregnancy as baseline and determine whether those associations are modified by presence of RA.In our RNA sequencing (RNA-seq dataset from 5 healthy women and 20 women with RA, normalized expression levels of 4,710 genes were significantly associated with pregnancy status (pre-pregnancy, first, second and third trimesters over time, irrespective of presence of RA (False Discovery Rate (FDR-adjusted p value<0.05. These genes were enriched in pathways spanning multiple systems, as would be expected during pregnancy. A subset of these genes (n = 256 showed greater than two-fold change in expression during pregnancy compared to baseline levels, with distinct temporal trends through pregnancy. Another 98 genes involved in various biological processes including immune regulation exhibited expression patterns that were differentially associated with pregnancy in the presence or absence of RA.Our findings support the hypothesis that the maternal immune system plays an active role during pregnancy, and also provide insight into other systemic changes that occur in the maternal transcriptome during pregnancy compared to the pre-pregnancy state. Only a small proportion of genes modulated by pregnancy were influenced by presence of RA in our data.

  18. Special features of high-risk pregnancies as factors in development of mental distress: a review

    Paula Borba Rodrigues

    Full Text Available Abstract Introduction: Approximately 22% of all pregnant women are classified as having high-risk pregnancies, which may involve feelings of vulnerability because of having a high-risk pregnancy, resulting in greater exposure to stressful feelings. Objective: To review aspects of high-risk pregnancy that can have a negative impact on the these women's mental health status. Method: Original articles were identified by conducting searches of the PubMed/MEDLINE, LILACS and SciELO databases, followed by a manual search of references to select articles and additional bibliographic material. Articles from the last 22 years were included in the review (1992-2014. Results: Fifteen articles were found that specifically studied high-risk pregnancies and mental health outcomes. Women with high-risk pregnancies exhibited a significantly higher level of stress and reported negative emotions as they dealt with stress and had worse emotional status than women with normal pregnancies. Researchers found that hospitalized pregnant women had higher levels of anxiety than non-hospitalized women. Studies of women going through normal and high-risk pregnancies show that women with normal pregnancies had good self-perceived quality of life. Conclusion: Special features of high-risk pregnancies could be factors in development of mental distress, in addition to psychological and social factors. Therefore, only a biopsychosocial research study would be able to identify the factors that can affect the quality of mental health during high-risk pregnancy.

  19. Pregnancy Associated with Systemic Lupus Erythematosus: Immune Tolerance in Pregnancy and Its Deficiency in Systemic Lupus Erythematosus--An Immunological Dilemma.

    Pregnancy is a physiological condition that requires immune tolerance to the product of conception. Systemic lupus erythematosus (SLE) is a disease with well-represented immune mechanisms that disturb immune tolerance. The association of pregnancy with systemic lupus erythematosus creates a particular immune environment in which the immune tolerance specific of pregnancy is required to coexist with alterations of the immune system caused by SLE. The main role is played by T regulatory (Treg) cells, which attempt to regulate and adapt the immune system of the mother to the new conditions of pregnancy. Other components of the immune system also participate to maintain maternal-fetal immune tolerance. If the immune system of pregnant women with SLE is not able to maintain maternal immune tolerance to the fetus, pregnancy complications (miscarriage, fetal hypotrophy, and preterm birth) or maternal complications (preeclampsia or activation of SLE, especially in conditions of lupus nephritis) may occur. In certain situations this can be responsible for neonatal lupus. At the same time, it must be noted that during pregnancy, the immune system is able to achieve immune tolerance while maintaining the anti-infectious immune capacity of the mother. Immunological monitoring of pregnancy during SLE, as well as of the mother's disease, is required. It is important to understand immune tolerance to grafts in transplant pathology.

    2002-01-01

    Full Text Available Introduction Pregnancy is an intriguing immunologic phenomenon. In spite of genetic differences, maternal and fetal cells are in close contact over the whole course of pregnancy with no evidence of either humoral and/or cellular immunologic response of mother to fetus as an allotransplant. The general opinion is that the fundamental protective mechanism must be located locally at the contact-plate, between the maternal and fetal tissues. Immunologic investigations proved the presence of specific systems which block the function of antipaternal maternal antibodies, as well as formation of cytotoxic maternal T-cells to paternal antigens. The system preventing rejection of graft during pregnancy is functioning at the level of maternal and fetal tissues. The protective mechanisms are coded by genes of MCH region, locus HLA-G. Protective mechanisms in the placenta The placenta protects itself against antibody-mediated damage. A high level of complement-regulatory proteins (CD46, CD55 and CD59, being the response to the synthesis of complement-fixing maternal antibodies to paternal antigens and regulation of the placental HLA expression as a preventive reaction of the feto-placental unit to the influence of maternal CTL, are the most important protective mechanisms of placenta. Protective mechanisms shared by the placenta and uterus Protective mechanisms common both for placenta and uterus are as follows: expressions of Fas ligand prevention of infiltration of activated immune cells, regulation of immunosuppression which prevents proliferation of immune cells and high natural immunity (Na cells and macrophages of the decidua.

    Obesity in our childbearing population has increased to epidemic proportions in developed countries; efforts to address this issue need to focus on prevention. The Health in Preconception, Pregnancy and Postbirth (HIPPP) Collaborative - a group of researchers, practitioners, policymakers and end-users - was formed to take up the challenge to address this issue as a partnership. Application of systems thinking, participatory systems modelling and group model building was used to establish research questions aiming to optimise periconception lifestyle, weight and health. Our goal was to reduce the burden of maternal obesity through systems change.

    The Office of Adolescent Health (OAH) sought to create a comprehensive set of performance measures to capture the performance of the Teen Pregnancy Prevention (TPP) program. This performance measurement system needed to provide measures that could be used internally (by both OAH and the TPP grantees) for management and program improvement as well as externally to communicate the program's progress to other interested stakeholders and Congress. This article describes the selected measures and outlines the considerations behind the TPP measurement development process. Issues faced, challenges encountered, and lessons learned have broad applicability for other federal agencies and, specifically, for TPP programs interested in assessing their own performance and progress.

Pregnancy may induce or even aggravate SLE, and SLE could affect the process and outcome of pregnancy, even lead to abortion, fetal death, stillbirth, fetal growth restriction or induce the development of neonatal lupus erythematosus (NLE). So it is important for clinicians to learn the changes in immunology and hormone levels in women with SLE that may contribute to pregnancy and fetus, to be knowledgeable about the indication for SLE patients to be pregnant, to apply effective immunosuppressants and right care, and to control patients' condition so as to ensure normal pregnancy and childbirth.

    2012-07-01

    The effect of maternal pre-eclampsia on neurological and cognitive development of children is not well known. A literature search of Ovid MEDLINE, EMBASE and CINAHL revealed differing opinions in the current literature. It would appear that there is uncertainty regarding the independent effects of preterm birth, birth weight and pre-eclampsia on early childhood development, complicated by the fact that most pre-eclamptic mothers are delivered preterm, and many such babies are growth restricted. To assess whether maternal hypertension in pregnancy was independently associated with additional support needs in children Retrospective cohort study Setting: Grampian region of Scotland Main outcome measure: The primary outcome of interest was whether a child had developed a record in the Support Needs System (Grampian). Secondary outcomes included the development of a particular disorder or deficiency for example, autism. Linkage of birth records of all singleton deliveries occurring in primigravidae between 1995 and 2008 in Aberdeen Maternity and Neonatal Databank with the Support Needs System (SNS) dataset in Grampian. The database from which the study population is derived - the Aberdeen Maternity and Neonatal Databank (AMND) has been in existence since 1950 The Support Needs System (SNS) is part of a Scottish-wide database recording information about children who have additional support needs for more than six months and has been utilised in Grampian since 1998. The first exposed cohort comprised children whose mothers had pre-eclampsia or eclampsia and the second, those whose mothers had gestational hypertension. Children with normotensive mothers formed the unexposed cohort. Hypertensive status in pregnancy was based on Davey and MacGillivray's classification of hypertensive disorders of pregnancy. Crude and adjusted odds ratios with 95% confidence Intervals of having a record in SNS in the presence of maternal pregnancy induced hypertension were calculated using

    2011-03-01

    The concept that pregnancy is associated with immune suppression has created a myth of pregnancy as a state of immunological weakness and, therefore, of increased susceptibility to infectious diseases. A challenging question is whether the maternal immune system is a friend or a foe of pregnancy. In this review, we discuss data associated to the role of the immune system during pregnancy. We propose a new paradigm in terms of the fetal-maternal immune interaction as well as the immunological response of the mother to microorganism. Our challenge is to better understand the immunology of pregnancy in order to deliver the appropriate treatment to patients with pregnancy complications as well as to determine public policies for the protection of pregnant women during pandemics.

    The renin-angiotensin system (RAS) has been implicated in pulmonary hypertension and pulmonary fibrosis. In the present study, we examined the effects of maternal exposure to captopril (2.85 mg/kg/day) during late pregnancy (G13-G21) on postnatal rat lung development. Treatment with captopril during late pregnancy caused a significant decrease in ACE activity in P0 rats. Body weight decreased at P0 (pcaptopril-treated rats. Lung weight of P0 and P8 pups was lower in treated-animals (pcaptopril-treated animals showed impaired alveolar formation, with enlarged distal airway spaces at P8, P15 and P30. Interalveolar wall distance measured by mean linear intercept increased in treated vs. age-matched animals at P8, P15 (pcaptopril-treated animals PCNA marker remains higher at all stages studied. α-Smooth muscle actin (α-SMA), a marker of fibroblast differentiation into myofibroblasts, was higher at the tips of developing secondary septa in captopril-treated lungs at P8 and P15. The increased expression of PCNA and α-SMA in treated pups suggest that beyond the effect caused by captopril, the developing lungs have the capacity to recover once the treatment was stopped. Taking together the low weight, histomorphological changes and increased expression of cellular markers caused by ACE inhibition during late pregnancy, it appears that the RAS could be an intrinsic factor involved in secondary septa formation during lung development.

    2013-01-01

    Maternal overweight and obesity in pregnancy has been associated with earlier age of menarche in daughters as well as reduced semen quality in sons. We aimed at investigating pubertal development in sons born by mothers with a high body mass index (BMI). The study included 2522 sons of mothers...... that during pregnancy in 1984-1987 were enrolled in a mother-child cohort and gave information on their pre-pregnancy height and weight from which we calculated their BMI. Information on sons' pubertal development, assessed by age when starting regular shaving, voice break, acne and first nocturnal emission...... indicators of pubertal development, results also indicated earlier pubertal development among sons of obese mothers. After excluding sons of underweight mothers in a subanalysis, we observed an inverse trend between maternal pre-pregnancy BMI and age at regular shaving, acne and first nocturnal emission...

    Full Text Available Letus present a unique clinical case course of autoimmune non paraneoplastic myasthenic syndrome of Lambert–Eaton on the background of pregnancy, in the 24 years old patient, with a 3-year history of the disease. Throughout the pregnancy, birth and early postpartum period, patient was taking a stable unmodified drug therapy, which allowed observing "natural" course for neuromuscular disease. The first trimester of pregnancy proceeded without deterioration of the myasthenic syndrome. From the middle of the second trimester (19–20 weeks gestation, and the entire third trimester until parturition, the patient's condition for neuromuscular disease has improved, which was accompanied by an increase in strength of proximal limb muscles and the positive dynamics of the basic parameters of neuromuscular transmission. Deliveries came on ime, preceeded safely through vaginal delivery, without weakness of generic forces. There was born clinically healthy male child, weighing 2970 g, growth of 52 cm (7/8 Apgar score. However , on the second day in the newborn was marked negative dynamics of muscular hypotonia, extinction of neonatal reflexes, sucking weakness, episodes of apnea, which required tube feeding and non invasive oxygen support. Neuromuscular defect was transient in character and resolved within 5–7 days with administration in the morning hours of 20 mg of prednisone parenteral. The child was discharged with full recovery of function of the neuromuscular system on the 13th day breastfed. Shortly after birth the mother appeared in a state of negative dynamics: the increased weakness of the proximal muscles of the legs and arms, deteriorated parameters of the neuromuscular conduct. By analogy with myasthenia there appeared the similar influence of pregnancy on the Lambert Eaton myasthenic syndrome: 1 improvmem of the neuromuscular disease in II–III trimester of pregnancy, 2 intact ability to birth vaginally, 3 no evidence of

    An early pregnancy risk scale, with scores ranging from 11 to 66 points from lower to higher risk, was constructed using variables associated with teenager's pregnancy. This scale was applied to 3000 female teenagers, coming from Metropolitan Santiago public schools. The sample was divided in three risk groups: group A (high risk) with scores equal or over 35 points, group B (low risk) with scores equal or below 20 points and group B (intermediate risk) with scores between 20.1 and 34.9 points. These girls were followed during 2 years. During this period, 84 girls became pregnant, 24 of 184 (13%) in group A, 60 of 2332 (2.6%) in group C and none of 307 in group B. There were 104 school desertions in group A and 37 in group B. To study associations and analyze risk, the sample was divided in two risk groups: high, with scores over 27 and low, with scores below 27. There was a high association between pregnancy risk score and the occurrence of pregnancy (RR 5.25 p school desertion (RR 3.32 p School desertion was predicted with a 74% sensitivity and 56% specificity. The importance variable weighing using multiple regression models, to improve the predictor's sensitivity and specificity, is discussed.

  18. Prepregnancy contraceptive use among teens with unintended pregnancies resulting in live births - Pregnancy Risk Assessment Monitoring System (PRAMS), 2004-2008.

    Science.gov (United States)

    2012-01-20

    Approximately 400,000 teens aged 15-19 years give birth every year in the United States (1), and the teen birth rate remains the highest in the developed world. Teen childbearing is a public health concern because teen mothers are more likely to experience negative social outcomes, including school dropout. In addition, infants of teen mothers are more likely to be low birth weight and have lower academic achievement, and daughters of teen mothers are more likely to become teen mothers themselves. To learn why teens wishing to avoid pregnancy become pregnant, CDC analyzed data from the 2004-2008 Pregnancy Risk Assessment Monitoring System (PRAMS). This report describes estimated rates of self-reported prepregnancy contraceptive use among white, black, and Hispanic teen females aged 15-19 years with unintended pregnancies resulting in live births. Approximately one half (50.1%) of these teens were not using any method of birth control when they got pregnant, and of these, nearly one third (31.4%) believed they could not get pregnant at the time; 21.0% used a highly effective contraceptive method (although less than 1% used one of the most effective methods, such as an intrauterine device [IUD]); 24.2% used the moderately effective method of condoms; and 5.1% used the least effective methods, such as rhythm and withdrawal. To decrease teen birth rates, efforts are needed to reduce or delay the onset of sexual activity, provide factual information about the conditions under which pregnancy can occur, increase teens' motivation and negotiation skills for pregnancy prevention, improve access to contraceptives, and encourage use of more effective contraceptive methods.

  19. Flares of systemic lupus erythematosus during pregnancy and the puerperium: prevention, diagnosis and management.

    Stojan, George; Baer, Alan N

    2012-07-01

    Systemic lupus erythematosus is a systemic autoimmune disease that primarily affects women in their reproductive age years. Pregnancy in systemic lupus erythematosus now has favorable outcomes for the majority of women. However, flares of disease activity, preeclampsia, fetal loss, intrauterine growth retardation and preterm birth are established risks of such pregnancies. Active lupus nephritis at the time of conception poses the greatest risk for disease flares and poor obstetric outcomes. Patients should delay conception until their lupus has been in remission for at least 6 months. In addition, certain lupus medications are potentially teratogenic and need to be stopped before conception. The signs and symptoms of a lupus flare may mimic those of normal pregnancy, impeding its recognition during pregnancy. Hydroxychloroquine, low-dose prednisone, pulse intravenous methylprednisolone and azathioprine are commonly used to treat lupus flares during pregnancy.

    Antenatal dietary lifestyle intervention and nutrition during pregnancy and early postnatal life are important for appropriate lifelong metabolic programming. Epidemiological evidence underlines the crucial role of increased birth weight as a risk factor for the development of chronic diseases of civilization such as obesity, diabetes and cancer. Obstetricians and general practitioners usually recommend milk consumption during pregnancy as a nutrient enriched in valuable proteins and calcium for bone growth. However, milk is not just a simple nutrient, but has been recognized to function as an endocrine signaling system promoting anabolism and postnatal growth by activating the nutrient-sensitive kinase mTORC1. Moreover, pasteurized cow's milk transfers biologically active exosomal microRNAs into the systemic circulation of the milk consumer apparently affecting more than 11,000 human genes including the mTORC1-signaling pathway. This review provides literature evidence and evidence derived from translational research that milk consumption during pregnancy increases gestational, placental, fetal and birth weight. Increased birth weight is a risk factor for the development of diseases of civilization thus involving key disciplines of medicine. With regard to the presented evidence we suggest that dietary recommendations promoting milk consumption during pregnancy have to be re-evaluated.

    Termination of pregnancy is the premature exit of the products of conception, which include the placenta, bag of waters, embryo or fetus from the uterus. In general, the term "termination of pregnancy" refers to non-medical termination of pregnancy, which is requested for different reasons other than medical ones. When such a request is made in countries where it is lawful, women have access to induced termination of pregnancy under lawful and limited conditions. However, in countries where the practice is illegal, women tend to suffer and die of complications from unsafe termination of pregnancy. Nowadays, there seems to be a worldwide trend towards the legalization of termination of pregnancy. The impact of international developments on women's rights has played an increasing role in improving access to termination of pregnancy. This article aims at describing how legalization of termination of pregnancy in France has become a right which is in accordance with international developments on women's rights.

    We performed a retrospective study of all systemic lupus erythematosus (SLE) pregnancies during a 10-year period (2006-2015) to describe the clinical features, maternal and foetal outcomes in our centre. There were 115 pregnancies in 86 women with SLE. Our patients had a mean age of 29.1 years (SD 5.80) and a mean disease duration of 44.63 months (SD 41.17). Fifteen patients had antiphospholipid syndrome (APS). Our patients had complicated pregnancies: 26.1% had SLE flares, 13.9% had pre-eclampsia and 45.1% needed caesarean sections. There were 23.3% foetal losses and 25% preterm deliveries in our patients. There was a higher rate of unplanned pregnancies and lupus flare among pregnancies with active SLE at conception. Pregnancies in lupus nephritis have higher incidence of lupus flares during pregnancy but similar maternal and foetal outcomes compared to those without nephritis. The prognostic indicators for adverse foetal outcome in our patients were flare of SLE (HR 4.08 [CI 95% 1.65-10.13, p Lupus pregnancies in our centre remained as high-risk pregnancies with significant maternal and foetal complications.

    The goal of the present paper is to discuss diagnosis, treatment approaches and histopathologic characteristics of breast cancer developing during pregnancy, based on our results and published literature data. We retrospectively evaluated clinical and pathologic features of tumors, treatment methods, decisions related to pregnancy and final outcome by eight pregnant patients with breast cancer. The patients' age varied from 26 to 36 years. At the last medical examination in October 2013, three among all eight patients were alive, two of them were without local and distant recurrence, and one patient has distant metastases and is carrying out a treatment. The aim of this paper was to discuss the characteristics of breast cancer developing during pregnancy. Retrospectively have been analyzed clinical-pathological characteristics of the tumors in eight pregnant women with breast cancer, the treatment, the management of the pregnancy, and the final outcome. The results are analyzed by comparing with data published in the literature.

    Objective To explore the relationship between the patterns of pronucleus and embryo development and pregnancy potential in the pronuclear stageMethods According to the number and distribution of nucleolar precursor bodies, the embryos at pronuclear stage were classified into 6 pronuclear patterns from 0 to 5, 16~18 h after in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). For each pattern, the subsequent embryonic morphology and the pregnancy rate were analyzed. Results Embryos of Pattern 0 developed to significantly more embryos with good quality and higher pregnancy potential than the embryos developing from other patterns (83.14% and 76.11% respectively, P<0.05). The pregnancy rate was decreased as less embryos of Pattern 0 were transferred . The pregnancy rate of the groups of only Pattern 0, with Pattern 0, and without Pattern 0 were 48.08%, 32.14% and 21.28% respectively (P<0.05).Conclusions The pronuclear patterns are of the predictive value of embryo development and pregnancy potential, which can be used as a new tool for the selection of embryos in IVF and ICSI.

    Full Text Available BACKGROUND: Adrenal neuroendocrine plays an important role in asthma. The activity of the sympathoadrenal system could be altered by early life events. The effects of maternal asthma during pregnancy on the adrenal medulla of offspring remain unknown. METHODOLOGY/PRINCIPAL FINDINGS: This study aims to explore the influence of maternal asthma during pregnancy on the development and function of adrenal medulla in offspring from postnatal day 3 (P3 to postnatal day 60 (P60. Asthmatic pregnant rats (AP, nerve growth factor (NGF-treated pregnant rats (NP and NGF antibody-treated pregnant rats (ANP were sensitized and challenged with ovalbumin (OVA; NP and ANP were treated with NGF and NGF antibody respectively. Offspring rats from the maternal group were divided into four groups: offspring from control pregnant rats (OCP, offspring from AP (OAP, offspring from NP (ONP, and offspring from ANP (OANP. The expressions of phenylethanolamine N-methyltransferase (PNMT protein in adrenal medulla were analyzed. The concentrations of epinephrine (EPI, corticosterone and NGF in serum were measured. Adrenal medulla chromaffin cells (AMCC were prone to differentiate into sympathetic nerve cells in OAP and ONP. Both EPI and PNMT were decreased in OAP from P3 to P14, and then reached normal level gradually from P30 to P60, which were lower from birth to adulthood in ONP. Corticosterone concentration increased significantly in OAP and ONP. CONCLUSION/SIGNIFICANCE: Asthma pregnancy may promote AMCC to differentiate into sympathetic neurons in offspring rats and inhibit the synthesis of EPI, resulting in dysfunction of bronchial relaxation.

    2016-01-01

    Full Text Available Background & aim: Thecurrent population of the world is seven billion, and developing countries account for its 97%. Approximately 210 million pregnancies annually occur worldwide and 75-80 million of them are reported to be unintended. Multiple factors can contribute to unintended pregnancy, which need to be assessed to design interventions reducing the incidence of unintended pregnancies.This study aimed to identify the determinants of unintended pregnancy among women of reproductive age in developing countries. Methods:This review of the literature was carried out by retrieving articles from various databases such as PubMed, Google scholar, and Science Direct and using mesh terms and phrases including ‘unintended pregnancy’, ‘contraception’, and ‘determinants of unintended pregnancy’. The reviewed studies included descriptive studies, population council reports, demographic and health survey reports, the United Nations Children's Fund statistics, and the World Health Organization reports. Results: The most common determinants of unintended pregnancy in the literature were reported under the headings of sociodemographic, socioeconomic, sociocultural, fertility related, contraceptive methods, and access related factors. Conclusion: Multiple factors can predict unintended pregnancy, and these findings have significant policy implications. Policymakers and healthcare providers can benefit from the evidence on determinants of unwanted pregnancy to design and implement policies and programs that can support couples to have their desired number of children, without facing unnecessary threats to their health. Furthermore, more studies are needed to be done in future to assess the available cost-effective interventions for reducing unintended pregnancy and ultimately, to improve women’s and children’s health.

We report a case with successful pregnancy in a patient with systemic lupus erythematosus and hypertension. A 39-year-old nulliparous woman presented with systemic lupus erythematosus with antinuclear and antiphospholipid antibodies, hypertension and recurrent pregnancy loss presented for assisted reproduction. The patient responded well to enoxaparin and prednisone during both assisted reproduction and prenatal treatment. This case report indicates that prescription of immunosuppressant and blood thinners can be safely recommended throughout the whole prenatal period in patients with systemic lupus erythematosus. Enoxaparin and prednisone may be prescribed concurrently during pregnancy.

    2014-03-01

    This review synthesizes new data from the studies published between 2011 and 2013, with particular focus on the different information gleaned by various study types. Population-based cohorts have demonstrated that women with systemic lupus erythematosus (SLE) have fewer live births and more pregnancy complications, but can have successful live births after having a poor outcome. A retrospective study suggests that only 4 months, not the traditional 6 months of disease quiescent SLE prior to pregnancy improves outcomes. Prospective studies identified several novel predictors of poor pregnancy outcomes, including uterine Doppler and laboratory findings. A prospective study found great success in transitioning to azathioprine from mycophenolate mofetil prior to pregnancy in patients with quiet lupus nephritis. Two retrospective analyses suggest that hydroxychloroquine may prevent congenital heart block in pregnancies exposed to SSA/Ro antibodies. Finally, the initial pregnancy data for belimumab suggest a high degree of transplacental transfer, but thus far no definitive link between belimumab and congenital abnormalities. Recent studies suggest both novel markers of poor pregnancy outcomes and new approaches to the management of lupus during pregnancy.

    2015-02-18

    Despite supportive public health policies (e.g., ACIP recommendations), the potential for providing clinical benefit through maternal immunization has yet to be fully realized. For vaccines already licensed and approved for use in adults, specific FDA approval for use during pregnancy to prevent disease in the mother and/or infant may have a significant impact on uptake and usage in pregnant women. In addition, for either a licensed vaccine or a novel vaccine, FDA approval for use during pregnancy would result in labeling that would serve as a resource for practitioners and would facilitate the safe and effective use of the vaccine during pregnancy. In the U.S., while many vaccines are approved for use in adults and most are not contraindicated for use in pregnant women, no vaccine is licensed for use specifically during pregnancy. Among the perceived obstacles hindering the clinical development of vaccines for use in pregnancy, regulatory issues are frequently cited. One aim of this article is to address the perceived regulatory obstacles. General concepts and regulatory considerations for clinical safety and effectiveness evaluations for vaccines indicated for use during pregnancy will be discussed. This discussion is not intended to establish data requirements or to articulate agency policy or guidance regarding specific vaccine products.

    Saeed Alqahtani

    Full Text Available Findings of a recent clinical study showed indomethacin has lower plasma levels and higher steady-state apparent clearance in pregnant subjects when compared to those in non-pregnant subjects reported in separate studies. Thus, in the current work we developed a pregnancy physiological based pharmacokinetic/pharmacodynamic (PBPK/PD model for indomethacin to explain the differences in indomethacin pharmacokinetics between pregnancy and non-pregnancy. A whole-body PBPK model with key pregnancy-related physiological changes was developed to characterize indomethacin PK in pregnant women and compare these parameters to those in non-pregnant subjects. Data related to maternal physiological and biological changes were obtained from literature and incorporated into the structural PBPK model that describes non-pregnant PK data. Changes in indomethacin area under the curve (AUC, maximum concentration (Cmax and average steady-state concentration (Cave in pregnant women were predicted. Model-simulated PK profiles were in agreement with observed data. The predicted mean ratio (non-pregnant:second trimester (T2 of indomethacin Cave was 1.6 compared to the observed value of 1.59. In addition, the predicted steady-state apparent clearance (CL/Fss ratio was almost similar to the observed value (0.46 vs. 0.42. Sensitivity analysis suggested changes in CYP2C9 activity, and to a lesser extent UGT2B7, as the primary factor contributing to differences in indomethacin disposition between pregnancy and non-pregnancy. The developed PBPK model which integrates prior physiological knowledge, in vitro and in vivo data, allowed the successful prediction of indomethacin disposition during T2. Our PBPK/PD model suggested a higher indomethacin dosing requirement during pregnancy.

    To investigate whether circulating 25-hydroxyvitamin D(3) [25(OH)D(3)] concentration in pregnancy is associated with neuropsychological development in infants. The Spanish population-based cohort study INfancia y Medio Ambiente Project recruited pregnant women during the first trimester of pregnancy between November 2003 and February 2008. Completed data on 1820 mother-infant pairs were used. Maternal plasma 25(OH)D(3) concentration was measured by high-performance liquid chromatography in pregnancy (mean 13.5 ± 2.1 weeks of gestation). Offspring mental and psychomotor scores were assessed by trained psychologists at age 14 months (range, 11-23) by using the Bayley Scales of Infant Development. β-Coefficients with 95% confidence intervals (CIs) of mental and psychomotor scores associated with continuous or categorical concentrations of maternal plasma 25(OH)D(3) were calculated by using linear regression analysis. The median plasma value of 25(OH)D(3) in pregnancy was 29.6 ng/mL (interquartile range, 21.8-37.3). A positive linear relationship was found between circulating concentrations of maternal 25(OH)D(3) concentrations in pregnancy and mental and psychomotor scores in the offspring. After adjustment for potential confounders, infants of mothers with 25(OH)D(3) concentrations in pregnancy >30 ng/mL showed higher mental score (β = 2.60; 95% CI 0.63-4.56) and higher psychomotor score (β = 2.32; 95% CI 0.36-4.28) in comparison with those of mothers with 25(OH)D(3) concentrations <20 ng/mL. Higher circulating concentration of maternal 25(OH)D(3) in pregnancy was associated with improved mental and psychomotor development in infants.

    Systemic sclerosis is a systemic, inflammatory, autoimmune disease affecting the skin and viscera, manifesting pathologically with microvascular lesions, perivascular infiltration by mononuclear cells and increased deposition of extracellular collagen. The rarity of the disease as well as its propensity to appear in the early 1940s, explain the low frequency of concurrent scleroderma and pregnancy. However, the marked female excess, as well as the trend for increasing maternal age due to social change and assisted reproductive technologies, renders heightened significance to issues of fertility, pregnancy course and pregnancy outcomes. In the past, scleroderma patients were thought to be at high risk for poor fetal and maternal outcome, but more current retrospective studies show that despite an increased frequency of prematurity and small for gestational age infants, overall maternal and neonatal survival is good. Hence, at present, with close monitoring and appropriate therapy most scleroderma patients can sustain a successful pregnancy. Therapy with hydroxychloroquine and low dose steroids as well as judicious use of intravenous immunoglobulins is permitted. Renal crisis remains the most dreaded complication of a scleroderma pregnancy and necessitates prompt institution of ACE inhibitor therapy despite its potential teratogenicity. In order minimize the risk for renal crisis, pregnancies should be avoided in rapidly progressive diffuse disease as such patients are at a greater risk for developing serious cardiopulmonary and renal problems early in the disease. This review shall focus on the bi-directional effects of scleroderma on fertility and pregnancy as well as on the management of pregnancy and delivery in the scleroderma patient.

    Aortic coarctation is an unusual cause of hypertension during pregnancy and its management is not clarified. We report transcatheter balloon dilatation and stenting for native aortic coarctation in a 22-year-old pregnant woman with severe and uncontrolled systemic hypertension. Arterial blood pressure could be successfully controlled with medical treatment during the rest of the pregnancy and the patient underwent uneventful delivery. No adverse events or recoarctation was observed during 24 months clinical follow-up. In conclusion, native aortic coarctation can be successfully treated during pregnancy with transcatheter therapy. More experience is needed to confirm the safety and efficacy of such management.

    Maternal asthma during pregnancy adversely affects pregnancy outcomes but identification of the cause/s, and the ability to evaluate interventions, is limited by the lack of an appropriate animal model. We therefore aimed to characterise maternal lung and cardiovascular responses and fetal-placental growth and lung surfactant levels in a sheep model of allergic asthma. Immune and airway functions were studied in singleton-bearing ewes, either sensitised before pregnancy to house dust mite (HDM, allergic, n = 7) or non-allergic (control, n = 5), and subjected to repeated airway challenges with HDM (allergic group) or saline (control group) throughout gestation. Maternal lung, fetal and placental phenotypes were characterised at 140 ± 1 days gestational age (term, ∼147 days). The eosinophil influx into lungs was greater after HDM challenge in allergic ewes than after saline challenge in control ewes before mating and in late gestation. Airway resistance increased throughout pregnancy in allergic but not control ewes, consistent with increased airway smooth muscle in allergic ewes. Maternal allergic asthma decreased relative fetal weight (-12%) and altered placental phenotype to a more mature form. Expression of surfactant protein B mRNA was 48% lower in fetuses from allergic ewes than controls, with a similar trend for surfactant protein D. Thus, allergic asthma in pregnant sheep modifies placental phenotype, and inhibits fetal growth and lung development consistent with observations from human pregnancies. Preconceptional allergen sensitisation and repeated airway challenges in pregnant sheep therefore provides an animal model to identify mechanisms of altered fetal development and adverse pregnancy outcomes caused by maternal asthma in pregnancy.

    Several outcomes of pregnancy after bariatric surgery are currently being studied. This cross-sectional, retrospective study evaluated the obstetric and perinatal outcomes of pregnancies in 19 women who underwent bariatric surgery, as well as the growth and development of their children, in the Southern Brazil. Among these women, 11 children were born prior to surgery and 32 were born post-surgery. The mean time between the surgery and the first pregnancy was 42.96 months. Preterm newborns were more common among the pre-surgery childbirths. Regarding growth, normal weights were observed in 27.3 % of the children in the pre-surgery births and obesity was observed in 54.5 %. In contrast, normal weights were observed in 59.4 % of the children born during the postoperative period and obesity was observed in 31.2 %. The average excess weight that the women lost prior to pregnancy was 64.88. Speech delays were found in three male children evaluated using the Denver Developmental Screening Test II. A statistical association was found between the interval from the surgery to the pregnancy and the outcome of the questionable Denver II test results (p = 0.011). Except for the large index of low birth weight, it can be concluded that pregnancy after bariatric surgery is safe. The growth rate was found to be adequate in the children born after the surgery, with reduced obesity. Although changes in speech development were detected, no factors were supported an association with pregnancy after bariatric surgery.

    This study evaluated some cytokines involved in the Th1-Th2 shift during pregnancy in patients with systemic lupus erythematosus (SLE) and healthy women. Twenty-seven consecutive successful pregnancies in 26 SLE patients and 28 pregnancies in 28 matched healthy subjects, as controls, were enrolled and prospectively studied. Sera obtained at first and third trimesters of pregnancy were tested for IL-1α, IL-1β, IL-2, IL-6, IL-8, IL-10, IL-12p70, INF-γ, and TNF-α with a highly sensitive, multiplexed sandwich ELISA (SearchLight Human Inflammatory Cytokine Array). Statistics were performed by SPSS package. IL-8 serum levels were higher in the first (Ppregnancy in SLE patients compared with controls, INF-γ serum levels in the third trimester (P=0.009), and IL-10 serum levels in the first and third trimesters (P=0.055 and Ppregnancy. Cytokine profile was similar in patients with and without lupus nephritis both in the first and in the third trimesters of pregnancy. IL-8 serum levels were lower in patients with a previous diagnosis of antiphospholipid antibody syndrome compared with those without, both in the first and in the third trimesters of pregnancy. In SLE patients, a lower than expected decrease in Th1 cytokine serum levels was observed in the third trimester of gestation which could contribute to a lower Th2 cytokine polarization during pregnancy.

    Despite documented effects on fetal brain development, little is currently known about the relationship between maternal pregnancy hypertension and child neuropsychological outcomes. This brief report examined the association between maternal hypertension during pregnancy and children's social cognition and executive functioning when children were 18 months, 3 years, and 4.5 years. A community sample of 501 families (23 hypertensive mothers; 478 nonhypertensive) was recruited when children were newborns. Social cognition (including theory of mind [ToM]) and executive functioning (EF) were measured using a battery of age-appropriate standardized and/or observational tasks. Information on pregnancy and prenatal factors were measured via maternal report when children were newborns. After controlling for prenatal and demographic covariates, the presence of hypertension difficulties during pregnancy was associated with all measures of social cognition, ToM, and EF. A secondary analysis comparing the hypertension group (n = 23) to a nonhypertensive matched control group (n = 23) supported the effect of pregnancy hypertension on children's social-cognitive and EF development. Future studies using obstetrical records are encouraged based on these preliminary findings.

    The aim of this study was to compare obstetric and perinatal outcome in teenage and non-teenage pregnancies. We analyzed retrospective data of 15,498 pregnant patients who delivered from March 2008 to April 2009 in Jawaharlal Institute of Postgraduate Medical Education and Research, a referral tertiary care and teaching hospital in Pondicherry, South India. Girls aged ≤ 19 years were compared with pregnancy outcomes in women aged > 19 years who delivered in the same hospital during the study period. A total of 620 teenage pregnancies were compared with 14,878 non-teenage women. The obstetric and perinatal outcome was compared in the study and control groups using t test with Yates correction. We calculated Odds ratio (OR), 95% confidence intervals(CI) and p values; p teenage pregnancy in the study was 4%. A signicant proportion of teenage mothers were in their first pregnancies and their mean age was 18.04 years. Our study showed a significantly higher incidence of anaemia, past dates, premature rupture of membranes (PROM), normal vaginal delivery, episiotomy, low birth weight, and a significantly lower incidence of caesarean sections/perineal tears in teenage mothers compared to other mothers. In contrast, the incidence of hypertension, intrauterine growth restriction of fetus, pre-term labour and postpartum haemorrhage were similar in both the groups. The data in our study should throw more light on the current thinking of the obstetrical problems facing teenage mothers, in which some of our results support and others refute several long held beliefs about the risks in teenage pregnancy. Early booking, adequate antenatal care and delivery by trained people should improve the obstetric and perinatal outcome in teenage pregnancies, which is still an unresolved problem inspite of various government programmes in developing countries.

    Full Text Available The aim of this study was to analyze the specificity and dynamics of psychomotor development in children from triplet pregnancy. The studied group was composed of siblings from triple pregnancy (T1, T2, T3, including two girls and one boy. This longitudinal study comprised three stages: stage I – children aged 25 months, stage II – children aged 29 months, and stage III – children aged 38 months. At each stage, the psychomotor development of children was examined with the Third Edition of Bayley Scales of Infant and Toddler Development (BSID-III and subjectively by their mother. Additionally, medical and nursing documentation was analyzed. Individual psychomotor development of children from triple pregnancy is different with regards to various spheres, and has different rates and dynamics throughout consecutive years. Psychomotor development of children from triple pregnancies is determined by gender and postnatal clinical parameters, i.e. birth weight, head circumference, postnatal morbidity, and prematurity-related conditions.

    Utero-placental growth and vascular development are critical for pregnancy establishment that may be altered by various factors including assisted reproductive technologies (ART), nutrition, or others, leading to compromised pregnancy. We hypothesized that placental vascularization and expression of angiogenic factors are altered early in pregnancies after transfer of embryos created using selected ART methods. Pregnancies were achieved through natural mating (NAT), or transfer of embryos from natural mating (NAT-ET), or in vitro fertilization (IVF) or activation (IVA). Placental tissues were collected on day 22 of pregnancy. In maternal caruncles (CAR), vascular cell proliferation was less (P<0.05) for IVA than other groups. Compared to NAT, density of blood vessels was less (P<0.05) for IVF and IVA in fetal membranes (FM), and for NAT-ET, IVF and IVA in CAR. In FM, mRNA expression was decreased (P<0.01–0.08) in NAT-ET, IVF and IVA compared to NAT for vascular endothelial growth factor (VEGF) and its receptor FLT-1, placental growth factor (PGF), neuropilin (NP) 1 and 2, angiopoietin (ANGPT) 1 and 2, endothelial nitric oxide synthase (NOS3), hypoxia inducible factor-1A (HIF1A), fibroblast growth factor (FGF) 2 and its receptor FGFR2. In CAR, mRNA expression was decreased (P<0.01–0.05) in NAT-ET, IVF and IVA compared to NAT for VEGF, FLT-1, PGF, ANGPT1 and TEK. Decreased mRNA expression for 12 of 14 angiogenic factors across FM and CAR in NAT-ET, IVF and IVA pregnancies was associated with reduced placental vascular development, which would lead to poor placental function and compromised fetal and placental growth and development.

    A professional website was created for the Pregnancy Loss Research Group to provide information relating to pregnancy loss and also the facilities at CUMH. A tailored content management system (CMS was created to push articles written to both website and mobile platforms so they only need to update articles once with changes appearing on both platforms without having to alter any code. The app was built using the mobile development framework PhoneGap which incorporates Javascript, HTML5 and CSS. Once the app is opened articles are pulled from the database into local storage so that there are no barriers to accessing information. When the app has a network connection a function calls the articles from the database to sync with the articles in local storage. This keeps articles up to date and facilitates offline reading. Articles are accessed via a fixed navigation bar in sections that mirror the main website. The app has a separate ToolKit with sections that are only available after the app user creates a profile. The Toolkit allows the user to map and record their experience of pregnancy loss using a number of tools including diary entries and photos. Users can write a diary entry or take a photo and save to review. Once the user submits a diary entry or photo the overall sentiment, negative or positive, is calculated against a word list with related scores. Emojis included in diary entries can also be calculated in the sentiment rating so that the informal way in which app users communicate with mobile devices can be properly assessed. For additional research purposes, the mobile app also includes a number of validated psychometric scales including Edinburgh Postnatal Depression Scale, Perceived Stress Scale and Self Evaluation Scale for the users to complete. The mobile app calculates the score for each scale and the scores per scale are displayed to allow researchers to investigate the emotional wellbeing of the users. The CMS then operates as a web user

    Full Text Available Background/Aims: Diabetes is well-known to influence endothelial function. Endothelial function and blood flow regulation might be different in diabetic and non-diabetic pregnancy. However, the impact of umbilical blood flow regulation in gestational diabetes on fetal development is unknown so far. Methods: In a prospective birth cohort study, we analyzed the association of the umbilical artery Doppler indices (pulsatility index, resistance index and systolic/diastolic ratio and fetal size measures (biparietal diameter, head circumference, abdominal circumference, femur length and birth weight in 519 non-gestational diabetes mellitus pregnancies (controls and 226 gestational diabetes mellitus pregnancies in middle (day 160.32 ±16.29 of gestation and late (day 268.12 ±13.04 of gestation pregnancy. Results: Multiple regression analysis considering confounding factors (gestational day of ultrasound examination, offspring sex, maternal body mess index before pregnancy, maternal age at delivery, maternal body weight at delivery and maternal hypertension showed that umbilical artery Doppler indices (pulsatility index, resistance index and systolic/diastolic ratio were associated with fetal head circumference and femur length in middle gestational diabetes mellitus pregnancy but not in non-gestational diabetes mellitus pregnancy. Head circumference, biparietal diameter, abdominal circumference and femur length in mid gestation were smaller in fetus of gestational diabetes mellitus pregnancy versus non-gestational diabetes mellitus pregnancy. In contrast to non-gestational diabetes mellitus pregnancy in late gestation, umbilical artery Doppler indices in gestational diabetes mellitus pregnancy were not associated with ultrasound measures of fetal growth. Birth weight was slightly increased in gestational diabetes mellitus pregnancy as compared to non-gestational diabetes mellitus pregnancy. Conclusions: The impact of umbilical blood flow on fetal

    The period of in utero development is one of the most critical windows during which adverse intrauterine conditions and exposures can influence the growth and development of the fetus as well as the child's future postnatal health and behavior. Maternal cigarette smoking during pregnancy remains a relatively common but nonetheless hazardous in utero exposure. Previous studies have associated prenatal smoke exposure with reduced birth weight, poor developmental and psychological outcomes, and increased risk for diseases and behavioral disorders later in life. Researchers are now learning that many of the mechanisms whereby maternal smoke exposure may affect key pathways crucial for proper fetal growth and development are epigenetic in nature. Maternal cigarette smoking during pregnancy has been associated with altered DNA methylation and dysregulated expression of microRNA, but a deeper understanding of the epigenetics of maternal cigarette smoking during pregnancy as well as how these epigenetic changes may affect later health and behavior remain to be elucidated. This article seeks to explore many of the previously described epigenetic alterations associated with maternal cigarette smoking during pregnancy and assess how such changes may have consequences for both fetal growth and development, as well as later child health, behavior, and well-being. We also outline future directions for this new and exciting field of research.

    Background Norms and stigma regarding pregnancy decisions (parenting, adoption, and abortion) are salient to maternal well-being, particularly for groups disproportionately affected by unintended pregnancy. However, there are few validated measures of individual-level perceptions of norms and stigma around pregnancy decisions. Additionally, little is known about variation in the content of norms regarding pregnancy decisions, and in stigma related to violations of these norms, across socio-demographic groups. Methods To create measures of perceived norms and stigma around pregnancy decisions, we developed and pre-tested 97 survey items using a mixed methods approach. The resulting survey was administered to 642 young adult women recruited from health department clinics and a public university campus in Birmingham, Alabama. Principal components factor analyses, reliability analyses, independent t-tests, and correlation analyses were conducted to establish the reliability and validity of scales. Additionally, multiple linear regression was used to identify demographic predictors of higher scale scores. Results Factor analyses revealed four subscales for each pregnancy decision: conditional acceptability, anticipated reactions, stereotypes/misperceptions, and attitudes. The total scales and their subscales demonstrated good internal reliability (alpha coefficients 0.72–0.94). The mean scores for each scale were significantly associated with each other, with related measures, and differed by sociodemographic characteristics. Specifically, in adjusted analyses, women in the university setting and White women expressed more negative attitudes and stigma around parenting. Minority women endorsed more negative norms and stigma around adoption. Finally, women from the health department, White women, and religious women expressed more negative norms and stigma around abortion. Conclusion Findings suggest that our multidimensional measures have good psychometric properties

  6. The development of parents-infant relationship in high-risk pregnancies and preterm birth

    Full Text Available The theory of human attachment, developed in 1951 by John Bowlby, has been widely applied across psychological, medical and social disciplines, especially in the context of developmental psychology; more recently it has been studied in the obstetric and neonatal fields. Numerous studies suggest that attachment patterns have an impact on the social, cognitive and emotional development of the off-spring, and are also believed to influence the individual’s psychosocial trajectories across the lifespan. Starting from empirical study of attachment, the psychological analysis of the experience of pregnancy allowed to introduce the concept of prenatal attachment, considered as the earlier internalized representation of the fetus that both parents acquire and elaborate during pregnancy. Recent studies have attempted to investigate how prenatal attachment develops in conditions of hazard, as for example in women hospitalized for a high-risk pregnancy or preterm birth. Literature showed that these clinical conditions may represent risk factors that, along with psychological distress and lack of familiar and social support, may adversely affect the mother-child relationship, with consequences on the psycosocial development of the off-spring. During pregnancy, medical team should assess mothers’ distress and attachment, perform procedures to positively develop attachment, and direct parents with low attachment scores to receive a professional, specific counseling. In the premature birth context, it is important to closely support mother-infant contact and to decrease maternal stress in every possible way during hospitalization and after discharge. Promotion of psychological wellbeing and attachment during pregnancy and after birth may serve as a crucial opportunity of improving maternal health practices, perinatal health and neonatal outcomes. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014

    2012-10-01

    We described a 30-year-old pregnant woman developing antinuclear antibodies (ANA)-negative systemic lupus erythematosus (SLE) accompanied with arthritis, malar rash, lymphopenia, autoimmune hemolytic anemia, pericardial and pleural effusion, proteinuria and seizures. All serum autoantibodies except anti-Ro antibody were negative. An artificially induced abortion was performed to prevent SLE deterioration. Steroid and cyclophosphamide therapy were effective for this patient. During the 2-year follow-up period, her ANA and other SLE-related autoantibodies in serum remained negative. This case suggests that ANA may not be required in the pathogenesis of SLE, even in the case with pregnancy, and ANA-negative SLE may also have a dangerous clinical course.

Objective: To evaluate the repercussions of the mild diabetes, considering two methodologies, on the pregnancy of Wistar rats and on the development of their offspring. Methods In the 1st induction, female offspring were distributed into two experimental groups: Group streptozotocin (STZ, n = 67: received the β-cytotoxic agent (100 mg STZ/kg body weight - sc on the 1st day of the life; and Non-diabetic Group (ND, n = 14: received the vehicle in a similar time period. In the adult life, the animals were mated. After a positive diagnosis of pregnancy (0, female rats from group STZ presenting with lower glycemia than 120 mg/dL received more 20 mg STZ/kg (ip at day 7 of pregnancy (2nd induction. The female rats with glycemia higher than 120 mg/dL were discarded because they reproduced results already found in the literature. In the mornings of days 0, 7, 14 and 21 of the pregnancy glycemia was determined. At day 21 of pregnancy (at term, the female rats were anesthetized and killed for maternal reproductive performance and fetal development analysis. The data were analyzed using Student-Newman-Keuls, Chi-square and Zero-inflated Poisson (ZIP Tests (p Results STZ rats presented increased rates of pre (STZ = 22.0%; ND = 5.1% and post-implantation losses (STZ = 26.1%; ND = 5.7%, reduced rates of fetuses with appropriate weight for gestational age (STZ = 66%; ND = 93% and reduced degree of development (ossification sites. Conclusion Mild diabetes led a negative impact on maternal reproductive performance and caused intrauterine growth restriction and impaired fetal development.

    The association between vitamin D deficiency in the first trimester and GDM development remains controversial in various ethnicities. We prospectively assessed whether pregnant women with vitamin D deficiency during early pregnancy had an increased likelihood of GDM development or poor fetal growth or pregnancy outcomes compared to those with sufficient vitamin D levels. Serum 25-OH-D measurements and fetal ultrasonograms were carried out at 12-14, 20-22, and 32-34 wk in 523 pregnant women. Each woman was screened for GDM at 24-28 wk. There were no differences in serum 25-OH-D levels at 12-14 wk or 22-24 wk of pregnancy between GDM and non-GDM women after adjusting for maternal age, BMI at prepregnancy, BMI at first visit, BMI at GDM screening, gestational age at sampling, previous history of GDM, vitamin D intake, and seasonal variation in sampling. The risk of GDM, insulin resistance, and impaired β-cell function had no association with serum 25-OH-D levels in crude or adjusted logistic regression analysis. GDM was not associated with maternal serum 25-OH-D deficiency during the first trimester or fetal growth during the first and second trimesters. Pregnancy outcomes such as miscarriage, Apgar 1, Apgar 5 and birth weight were independent of maternal serum 25-OH-D levels during the first, second and third trimester of pregnancy. In conclusion, neither GDM prevalence nor fetal growth during pregnancy is associated with vitamin D deficiency at the first trimester in Korean women. Pregnancy outcomes are also independent of maternal vitamin D status.

    Little is known about the relationships between pregnancy cravings, maternal diet, and development of abnormal glucose tolerance. We examined relationships of pregnancy cravings with dietary intake and risk of developing isolated hyperglycemia (IH), impaired glucose tolerance (IGT), or gestational diabetes (GDM) later in pregnancy. Among 2,022 mothers in Project Viva, a prospective birth cohort recruited from medical practices in eastern Massachusetts between 1999 and 2002, we assessed type of pregnancy craving based on self-report at mean gestation of 10.9 weeks. The outcomes were cross-sectional dietary intake from a food frequency questionnaire and incident IH, IGT, or GDM determined by glucose tolerance screening at 26 to 28 weeks. We used linear regression to analyze the cross-sectional relationships between pregnancy cravings and dietary intake and multinomial logistic regression to analyze the prospective relationships among pregnancy cravings and development of IH, IGT, or GDM. During the first trimester, 443 (22%) women craved sweets, 225 (11%) craved salty foods, 261 (13%) craved savory foods, and 100 (4.9%) craved starchy foods. Sweet cravings were associated with increased intake of sucrose (1.9 g/day; 95% CI 0.1 to 3.7), total fat (1.5 g/day; 95% CI 0.1 to 2.9), and saturated fat (0.8 g/day; 95% CI 0.2 to 1.4); salty cravings were associated with increased fiber (0.7 servings/day; 95% CI -0.1 to 1.6); savory cravings were associated with increased n-3 fatty acids (0.10 g/day; 95% CI 0.02 to 0.17); and starchy cravings were associated with increased carbohydrates (8.0 g/day; 95% CI 0.3 to 15.7) and decreased total fat (-2.6 g/day; 95% CI -5.2 to -0.1). Salty cravings were associated with lower risk of GDM (adjusted odds ratio 0.34, 95% CI 0.12-0.97). New cravings in the first trimester of pregnancy were associated with dietary intake. Craving salty foods may predict reduced risk of developing GDM, whereas craving sweet food does not appear to alter one

    2007-01-01

    Pregnancy in a woman with Systemic Lupus Erythematosus (SLE) can be complicated by both lupus activity and pregnancy mishaps. The majority of recent studies demonstrate an increase in lupus activity during pregnancy, perhaps exacerbated by hormonal shifts required to maintain pregnancy. Increased lupus activity, in turn, prompts an elevated risk for poor pregnancy outcomes, including stillbirth, preterm birth, low birth weight, and preeclamspsia. Fortunately, the majority of pregnancies in wo...

    Full Text Available Pregnancy in patients with lupus nephritis is a challenging clinical situation. Although not absolutely contraindicated, it is associated with increased risk for foetal and maternal complications, including foetal loss, preterm delivery, intrauterine growth retardation, hypertension, pre-eclampsia, nephritis flare, and, rarely, maternal death. The complication rate is further increased in the presence of antiphospholipid antibodies or the antiphospholipid syndrome. Proliferative classes of nephritis (III and IV also appear to confer excess risk for complications. Immunosuppressives such as cyclophosphamide and mycophenolate, and antihypertensives such as angiotensin-converting-enzyme (ACE inhibitors and angiotensin receptor blockers need to be stopped due to teratogenic effects. Agents like corticosteroids, azathioprine, and probably calcineurin inhibitors are considered compatible with gestation. Lupus activity needs to be assessed and carefully monitored. Thrombotic risk due to antiphospholipid antibodies, thrombotic events, or nephrosis needs to be evaluated and managed accordingly, with the use of aspirin and/or unfractioned or low molecular weight heparin. Differentiating between severe pre-eclampsia and lupus nephritis flare might require a renal biopsy, which might not always be feasible, for example after the 32nd gestational week or in a setting of uncontrolled hypertension or thrombocytopaenia. A 6-month history of quiescent disease on non-teratogenic agents seems to be associated with best chance for favourable outcomes. Pregnancy is optimally managed by a multidisciplinary team of experienced specialists, and close monitoring for disease activity during gestation; additionally, follow-up for maternal flare postpartum is also advised.

    Full Text Available Exposure to an adverse environment in utero appears to programme physiology and metabolism permanently, with long-term consequences for health of the fetus or offspring. It was observed that the offspring from dams submitted to high-sodium intake during pregnancy present disturbances in renal development and in blood pressure. These alterations were associated with lower plasma levels of angiotensin II (AII and changes in renal AII receptor I (AT1 and mitogen-activated protein kinase (MAPK expressions during post natal kidney development. Clinical and experimental evidence show that the renin-angiotensin system (RAS participates in renal development. Many effects of AII are mediated through MAPK pathways. Extracellular signal-regulated protein kinases (ERKs play a pivotal role in cellular proliferation and differentiation. In conclusion, high-sodium intake during pregnancy and lactation can provoke disturbances in renal development in offspring leading to functional and structural alterations that persist in adult life. These changes can be related at least in part with the decrease in RAS activity considering that this system has an important role in renal development.

  2. Effects of prenatal stress on pregnancy and human development: mechanisms and pathways

    Coussons-Read, Mary E

    2013-01-01

    A growing body of research shows that prenatal stress can have significant effects on pregnancy, maternal health and human development across the lifespan. These effects may occur directly through the influence of prenatal stress-related physiological changes on the developing fetus, or indirectly through the effects of prenatal stress on maternal health and pregnancy outcome which, in turn, affect infant health and development. Animal and human studies suggest that activation of the maternal stress response and resulting changes in endocrine and inflammatory activity play a role in the aetiology of these effects. Ongoing research is focusing on clarifying these mechanisms, understanding the role of racial and cultural factors in these effects, and examining the epigenetic and transgenerational influences of prenatal stress.

    2015-01-01

    The function of the liver is particularly affected by the unique physiologic milieu of the pregnancy. Pregnancy-related liver diseases encompass a spectrum of different etiologies that are related to gestation or one of its complications. Hepatic calcification, a rare entity, is usually associated with infectious, vascular, or neoplastic lesions in the liver. To the best of our knowledge, only one case of rapidly occurring pregnancy-related intrahepatic calcification has been documented in a patient with severe eclampsia or hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome. Here we present a case of immediate “postpartum” acute fatty liver of pregnancy (AFLP) in a 23-year-old hypertensive primigravida, complicated by acute renal dysfunction who developed dense intrahepatic calcification in less than a month after the initial diagnosis. A multidisciplinary approach for the management was used, to which the patient responded aptly. This case illustrates the first description of intrahepatic calcification in AFLP syndrome and highlights some of the challenges met in making the final diagnosis. PMID:27785315

    Studies on the impact of micronutrient levels during different pregnancy periods on child psychomotor functions are limited. The aim of this study was to evaluate the association between maternal plasma concentrations of selected micronutrients, such as: copper (Cu), zinc (Zn), selenium (Se), and child neuropsychological development. The study population consisted of 539 mother-child pairs from Polish Mother and Child Cohort (REPRO_PL). The micronutrient levels were measured in each trimester of pregnancy, at delivery and in the cord blood. Psychomotor development was assessed in children at the age of 1 and 2 years using the Bayley Scales of Infant and Toddler Development. The mean plasma Zn, Cu and Se concentrations in the 1st trimester of pregnancy were 0.91±0.27mg/l, 1.98±0.57mg/l and 48.35±10.54μg/l, respectively. There were no statistically significant associations between Cu levels and any of the analyzed domains of child development. A positive association was observed between Se level in the 1st trimester of pregnancy and child language and motor skills (β=0.18, p=0.03 and β=0.25, p=0.005, respectively) at one year of age. Motor score among one-year-old children decreased along with increasing Zn levels in the 1st trimester of pregnancy and in the cord blood (β=-12.07, p=0.003 and β=-6.51, p=0.03, respectively). A similar pattern was observed for the association between Zn level in the 1st trimester of pregnancy and language abilities at one year of age (β=-7.37, p=0.05). Prenatal Zn and Se status was associated with lower and higher child psychomotor abilities, respectively, within the first year of life. Further epidemiological and preclinical studies are necessary to confirm the associations between micronutrient levels and child development as well as to elucidate the underlying mechanisms of their effects.

    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 ma...

    2017-01-01

    Full Text Available The possible association between maternal exposure to pyrethroid insecticides (PYRs during pregnancy and infant development was explored. Levels of exposure to PYRs was assessed by metabolite (3-phenoybenzoic acid, 3-PBA concentration in maternal spot urine sampled in the first trimester of index pregnancy, and infant development was assessed at 18 months of age using the Kinder Infants Development Scale (KIDS, which is based on a questionnaire to the caretaker. The relationship between KIDS score and maternal urinary 3-PBA levels was examined by a stepwise multiple regression analysis using biological attributes of the mother and infant, breast feeding, and nursing environment as covariates. The analysis extracted 3-PBA and the nursing environment as significant to explain the KIDS score at 18 months of age with positive partial regression coefficients. Inclusion of fish consumption frequency of the mother during pregnancy as an independent variable resulted in the selection of fish consumption as significant, while the two variables were marginally insignificant but still with a positive coefficient with the KIDS score. The result suggested a positive effect of maternal PYR exposure on infant development, the reason for which is not clear, but an unknown confounding factor is suspected.

    2011-02-01

    Adult stem cells of the mammary gland (MaSCs) are a highly dynamic population of cells that are responsible for the generation of the gland during puberty and its expansion during pregnancy. In recent years significant advances have been made in understanding how these cells are regulated during these developmentally important processes both in humans and in mice. Understanding how MaSCs are regulated is becoming a particularly important area of research, given that they may be particularly susceptible targets for transformation in breast cancer. Here, we summarize the identification of MaSCs, how they are regulated and the evidence for their serving as the origins of breast cancer. In particular, we focus on how changes in MaSC populations may explain both the increased risk of developing aggressive ER/PR(-) breast cancer shortly after pregnancy and the long-term decreased risk of developing ER/PR(+) tumors.

    For successful embryo implantation, endometrial stromal cells must undergo functional and morphological changes, referred to as decidualization. However, the molecular mechanisms that regulate implantation and decidualization are not well defined. Here we demonstrate that the estradiol- and progesterone-regulated microRNA (miR)-200 family was markedly down-regulated in mouse endometrial stromal cells prior to implantation, whereas zinc finger E-box binding homeobox-1 and -2 and other known and predicted targets were up-regulated. Conversely, miR-200 was up-regulated during in vitro decidualization of human endometrial stromal cells. Knockdown of miR-200 negatively affected decidualization and prevented the mesenchymal-epithelial transition-like changes that accompanied decidual differentiation. Notably, superovulation of mice and humans altered miR-200 expression. Our findings suggest that hormonal alterations that accompany superovulation may negatively impact endometrial development and decidualization by causing aberrant miR-200 expression.

    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 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.

    Folate intake during pregnancy has been associated with improved neuropsychological development in children, although the effects of high dosages of folic acid (FA) supplements are unclear. To examine the association between the use of high dosages of FA supplements during pregnancy and child neuropsychological development after the first year of life. The multicenter prospective mother-child cohort Infancia y Medio Ambiente (INMA) Project recruited pregnant women from 4 areas of Spain (Asturias, Sabadell, Gipuzkoa, and Valencia) between November 2003 and January 2008. Pregnant women completed an interviewer-administered questionnaire on the usual dietary folate intake and FA supplements at 10 to 13 weeks and 28 to 32 weeks of gestation. The main analyses were based on a sample of 2213 children with complete information on neuropsychological development and FA supplement intake during pregnancy. Multiple linear and logistic regression analyses were used to explore the effects of FA supplements on child neuropsychological development. Neuropsychological development was assessed using the Bayley Scales of Infant Development. We calculated mental scale and psychomotor scale scores. One SD below the mean established a delay in neurodevelopment (score 5000 μg/d). In multivariate analysis, we observed that children whose mothers used FA supplement dosages higher than 5000 μg/d during pregnancy had a statistically significantly lower mean psychomotor scale score (difference, -4.35 points; 95% CI, -8.34 to -0.36) than children whose mothers used a recommended dosage of FA supplements (400-1000 μg/d). An increased risk of delayed psychomotor development (psychomotor scale score <85) was also evident among children whose mothers took FA supplement dosages higher than 5000 μg/d, although the association was not statistically significant (odds ratio = 1.59; 95% CI, 0.82-3.08). To our knowledge, this is the first time a detrimental effect of high dosages of FA supplements

    Background Previous studies have shown an association between total excessive gestational weight gain and hypertension in pregnancy. However, this may be a reflection of excessive water retention associated with the pathophysiology of hypertensive disorders of pregnancy. Early excessive weight gain, prior to the third trimester, results in greater maternal fat deposition and inflammation, which has also been associated with the development of hypertension. By focusing on early excessive weight gain, the association between maternal weight gain and the future development of hypertension can be examined. Objective To evaluate the association between early excessive maternal weight gain and the development of hypertension during pregnancy. Study Design This was a secondary analysis of a longitudinal cohort study of 1,441 women without chronic hypertension who were enrolled in a prospective study evaluating maternal angiogenic factors and the prediction of preeclampsia. Initial body mass index (BMI) was calculated by weight and height at the first study visit. Early excessive maternal weight gain was defined as weight gain by 28 weeks that exceeded the Institute of Medicine (IOM) guidelines and was calculated utilizing the maximum amount of weight gain per week recommended by the IOM based on the patient's starting BMI (normal: 0.45 kg; overweight: 0.32 kg; obese: 0.27 kg). Hypertension was defined as a sustained systolic blood pressure of ≥140 mm Hg or a diastolic blood pressure of ≥90 mm Hg. Logistic regression was used to determine the association between early excessive weight gain, initial BMI, and the development of hypertension, including gestational hypertension and preeclampsia, during pregnancy. Results Of 1,441 women, 767 (53.2%) had weight gain that exceeded the IOM guidelines in the first 28 weeks and 154 (10.8%) developed hypertension during pregnancy. Women whose weight gain exceeded the IOM guidelines were more likely to develop

    A low-cost, high-efficiency dish-Stirling solar thermal-electric power system is being developed for test in 1981. System components are the solar concentrator, receiver, fossil fuel combustor, thermal energy storage (TES), engine-generator, and power processing. System conceptualization is completed and design is in progress. Two receiver alternatives are being evaluated, a direct-coupled receiver-engine configuration with no TES and a heat pipe receiver with TES. System cost projections are being made. Goals for the system development task are (1) to develop an advanced dish-Stirling technology, utilizing a team of industrial contractors, (2) to demonstrate that technology at the system level, and (3) to determine how to achieve low production cost.

  2. Risk factors for the development of stress urinary incontinence during pregnancy in primigravidae: a review of the literature.

    Sangsawang, Bussara

    2014-07-01

    The most common type of urinary incontinence (UI) in pregnant women is stress urinary incontinence (SUI). The number of pregnant women with SUI was variable, the prevalence ranged from 18.6% to 75% and increased with gestational age. It can affect the quality of life (QoL) of approximately 54.3% of all pregnant women in four domains including physical activity, travel, social relationships and emotional health. Pregnancy is one of the main risk factors for the development of SUI in young women. Physiological changes during pregnancy, such as increasing pressure of the growing uterus and fetal weight on the pelvic floor muscle (PFM) throughout pregnancy, together with pregnancy-related hormonal changes such as increased progesterone, decreased relaxin, and decreased collagen levels, may lead to reduced strength and supportive and sphincteric function of the PFM. Pregnancy may associate with the reduction of the PFM strength which can develop the SUI. However, the exact causes of pregnancy-related SUI remain unclear. Multiple factors have been found to be associated with the development of SUI during pregnancy. In genetic risk factors, aging is an important role in SUI development. The other risk factors such as obesity, smoking, constipation, pre-pregnancy SUI, gestational diabetes mellitus (GDM), and pelvic floor muscle exercise (PFME) that utilized preventive strategies can reduce SUI in pregnant women. The purpose of this review is to identify the risk factors for the development of SUI in pregnant women. These understanding can be useful for health professions to inform and counsel the pregnant women to prevent and reduce the risk factors that contribute to the development of SUI during pregnancy and postpartum period.

    The INMA (INfancia y Medio Ambiente [Spanish for Environment and Childhood]) project is a cooperative research network. This project aims to study the effects of environment and diet on fetal and early childhood development. This article aims to present the air pollutant exposure protocol during pregnancy and fetal and early childhood development of the INMA project. The information to assess air pollutant exposure during pregnancy is based on outdoor measurement of air pollutants (nitrogen dioxide [NO2], volatile organic compounds [VOC], ozone, particulate matter [PM10, PM2,5 ] and of their composition [polycyclic aromatic hydrocarbons]); measurement of indoor and personal exposure (VOC and NO2); urinary measurement of a biological marker of hydrocarbon exposure (1-hydroxypyrene); and data gathered by questionnaires and geographic information systems. These data allow individual air pollutant exposure indexes to be developed, which can then be used to analyze the possible effects of exposure on fetal development and child health. This protocol and the type of study allow an approximation to individual air pollutant exposure to be obtained. Finally, the large number of participants (N = 4,000), as well as their geographic and social diversity, increases the study's potential.

    Full Text Available The aim of the present study was to compare the toxic effects of fluoxetine (F (8 and 16 mg/kg and venlafaxine (V (40 and 80 mg/kg administered during the third week of pregnancy on early development of rats. Both antidepressants were administered by gavage on pregnancy days 15 to 20 to groups of 10 to 12 animals each. Duration of gestation, food and water consumption, number of live pups and birth weight were recorded. Litters were culled to six pups at birth (day 1 and followed for growth until weaning (day 25. On day 60, a male and a female from each litter were injected with the 5-HT1 agonist, 5-methoxy-N,N-dimethyltryptamine (6 mg/kg, ip and the serotonergic syndrome was graded. Fluoxetine but not venlafaxine reduced the duration of pregnancy when compared to the control (C group (F = 21.1 days and C = 21.6 days, mean, P<0.02; maximum = 22 days and minimum = 21 days in both groups. The highest doses of both fluoxetine, 16 mg/kg (F16, and venlafaxine, 80 mg/kg (V80, reduced the food intake of pregnant rats, resulting in different rates of body weight gain during treatment (from pregnancy day 15 to day 20: F16 = 29.0 g, V80 = 28.7 g vs C = 39.5 g (median. Birth weight was influenced by treatment and sex (P<0.05; two-way ANOVA. Both doses of fluoxetine or venlafaxine reduced the body weight of litters; however, the body weight of litters from treated dams was equal to the weight of control litters by the time of weaning. At weaning there was no significant difference in weight between sexes. There was no difference among groups in number of live pups at birth, stillbirths, mortality during the lactation period or in the manifestation of serotonergic syndrome in adult rats. The occurrence of low birth weight among pups born to dams which did not show reduced food ingestion or reduction of body weight gain during treatment with lower doses of fluoxetine or venlafaxine suggests that these drugs may have a deleterious effect on prenatal

    2016-04-01

    The increased risk of adverse pregnancy and childbirth outcomes demonstrated for many non-Western migrants in Europe, Australia and North America may be due to inadequate use and suboptimal quality of care. It is indicated that a poor user-provider interaction leads to inequity of pregnancy and delivery care. This review demonstrated that there is no evidence of best practice antenatal care for migrant women. Health system interventions for improved maternal and child health among migrants should be based on thorough needs assessments, contextual understanding and involvement of the target group and health-care providers. We present the Danish MAMAACT study as a strategic perspective on how to move forward, and we describe methodological steps in intervention development. Based on a mixed method needs assessment, the MAMAACT study aimed to enhance the communication between migrant women and midwives during antenatal care regarding warning signs of pregnancy and how to access acute care.

    1993-09-01

    This paper presents the results of a study of state-wide adolescent pregnancy prevention coalitions. Key informants in five states throughout the southern United States were given semi-structured interviews regarding the adolescent pregnancy prevention coalitions in their states. From these interviews and other documents, conclusions were drawn regarding the nature and importance of the environments within which these coalitions operate, the universe of activities in which coalitions engage, and the stages of development of these coalitions. Katz and Kahn's model of social organizations served as the basis for understanding coalitions in terms of these three considerations. Future research should consider the utility of organizational models that can explain more fully the organization--committee hybrid structure that tends to characterize these coalitions.

    Intrahepatic cholestasis of pregnancy (ICP) is a disorder of liver function, commonly occurring in the third trimester but sometimes also as soon as the end of the second trimester of pregnancy. Symptoms of this disorder include pruritus, plus abnormal values of bile acids and hepatic transaminases. After birth, symptoms disappear and liver function returns to normal. Though ICP is relatively non-complicated and often symptomatically mild from the point-of-view of the mother, it presents a serious risk to the fetus, making this disease the subject of great interest. The etiology and pathogenesis of ICP is multifactorial and as yet not fully elucidated. Hormonal factors likely play a significant role, along with genetic as well as exogenous factors. Here we summarize the knowledge of changes in steroid hormones and their role in the development of intrahepatic cholestasis of pregnancy. In addition, we consider the role of exogenous factors as possible triggers of steroid hormone changes, the relationship between metabolic steroids and bile acids, as well as the combination of these factors in the development of ICP in predisposed pregnant women.

  14. Benefits of Docosahexaenoic Acid, Folic Acid, Vitamin D and Iodine on Foetal and Infant Brain Development and Function Following Maternal Supplementation during Pregnancy and Lactation

    Directory of Open Access Journals (Sweden)

    Nancy L. Morse

    2012-07-01

    Full Text Available Scientific literature is increasingly reporting on dietary deficiencies in many populations of some nutrients critical for foetal and infant brain development and function. Purpose: To highlight the potential benefits of maternal supplementation with docosahexaenoic acid (DHA and other important complimentary nutrients, including vitamin D, folic acid and iodine during pregnancy and/or breast feeding for foetal and/or infant brain development and/or function. Methods: English language systematic reviews, meta-analyses, randomised controlled trials, cohort studies, cross-sectional and case-control studies were obtained through searches on MEDLINE and the Cochrane Register of Controlled Trials from January 2000 through to February 2012 and reference lists of retrieved articles. Reports were selected if they included benefits and harms of maternal supplementation of DHA, vitamin D, folic acid or iodine supplementation during pregnancy and/or lactation. Results: Maternal DHA intake during pregnancy and/or lactation can prolong high risk pregnancies, increase birth weight, head circumference and birth length, and can enhance visual acuity, hand and eye co-ordination, attention, problem solving and information processing. Vitamin D helps maintain pregnancy and promotes normal skeletal and brain development. Folic acid is necessary for normal foetal spine, brain and skull development. Iodine is essential for thyroid hormone production necessary for normal brain and nervous system development during gestation that impacts childhood function. Conclusion: Maternal supplementation within recommended safe intakes in populations with dietary deficiencies may prevent many brain and central nervous system malfunctions and even enhance brain development and function in their offspring.

    The aim of this research was to compare the morphological aspects during the development of pregnancy in dogs and cats, distinguishing features of the fetal membranes, such as yolk sac evolution and differentiation of hemangioblasts, and the degree of elaboration of the amnion and allantois. Canine and feline placentae from 20, 24, 35, 45 and 55 d of pregnancy were perfusion-fixed for histological investigation and vascular corrosion casts were produced. The casts were prepared for scanning electron microscopy (SEM) and the embryo and fetal membrane development was analyzed. The growth patterns of the conceptuses were compared with the organization of the placentation process, and changes of the morphology during pregnancy were recorded. In feline placentae, an incomplete zonary shape was present in 62.5% out of 60 studied cases. This was located distal to the insertion of the umbilical cord. In the lamellar zone, the interhemal membrane or placental barrier resembled endotheliochorial conditions, and the maternal-fetal microvascular blood flow interrelationship was of simple crosscurrent type. Dogs have a zonary placenta, completely surrounding the fetus, and complex lamellar organization of maternal and fetal tissues. At the border, two marginal hematomes with green colouration delimited the central placental girdle. The yolk sac consisted of one large sacculation with an inverted "T" shape and an enormous number of blood vessels; it had hemangioblast cells in contact with the epithelium. The amnion was avascular in early stages, but became vascularized by blood vessels of the internal allantoic membrane in later stages of pregnancy by intrinsic relation.

    2016-12-01

    Full Text Available Introduction: This study aimed to examine the role of prenatal stressful events in mothers of children and adolescents with autistic disorder (AD. Methods: This case-control study was conducted in 2014. A total number of 115 children and adolescents with AD were selected by convenience method from the autism rehabilitation centers in Tabriz, Iran. Moreover, 112 typically developing (TD children and adolescents were selected from public schools using a random clustering method. Two groups were matched in terms of mother's and child's age and mother's educational level. The Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS semi-structured diagnostic interview was used to evaluate the presence of psychiatric disorders. The diagnosis of AD was made based on the DSM-IV criteria during separate diagnostic interviews by two child and adolescent psychiatrists. The life stressful events’ inventory was used to assess the presence of stressful events during pregnancy. Results: According to Fisher's exact test, the frequency of stressful life events including failure to achieve life goals, high debt, frequent marital conflict, conflict with spouse's family, changes in sleeping habits, and sexual difficulties in the mothers of AD children during pregnancy was significantly higher than the mothers of TD children. Also, mothers of AD children reported significantly higher frequency for the positive stressful life events including the major job progress, starting or finishing education, change of education, location, and summer vacation during pregnancy. Conclusion: Some stressful life events in mothers during pregnancy may be considered as risk factors for developing AD in their children. Further researches are needed to establish the results of this study.

  17. The Lin28/Let-7 system in early human embryonic tissue and ectopic pregnancy.

    Full Text Available Our objective was to determine the expression of the elements of the Lin28/Let-7 system, and related microRNAs (miRNAs, in early stages of human placentation and ectopic pregnancy, as a means to assess the potential role of this molecular hub in the pathogenesis of ectopic gestation. Seventeen patients suffering from tubal ectopic pregnancy (cases and forty-three women with normal on-going gestation that desired voluntary termination of pregnancy (VTOP; controls were recruited for the study. Embryonic tissues were subjected to RNA extraction and quantitative PCR analyses for LIN28B, Let-7a, miR-132, miR-145 and mir-323-3p were performed. Our results demonstrate that the expression of LIN28B mRNA was barely detectable in embryonic tissue from early stages of gestation and sharply increased thereafter to plateau between gestational weeks 7-9. In contrast, expression levels of Let-7, mir-132 and mir-145 were high in embryonic tissue from early gestations (≤ 6-weeks and abruptly declined thereafter, especially for Let-7. Opposite trends were detected for mir-323-3p. Embryonic expression of LIN28B mRNA was higher in early stages (≤ 6-weeks of ectopic pregnancy than in normal gestation. In contrast, Let-7a expression was significantly lower in early ectopic pregnancies, while miR-132 and miR-145 levels were not altered. Expression of mir-323-3p was also suppressed in ectopic embryonic tissue. We are the first to document reciprocal changes in the expression profiles of the gene encoding the RNA-binding protein, LIN28B, and the related miRNAs, Let-7a, mir-132 and mir-145, in early stages of human placentation. This finding suggests the potential involvement of LIN28B/Let-7 (deregulated pathways in the pathophysiology of ectopic pregnancy in humans.

    The aim of this study was to develop a mother-child linked database consisting of all eligible active duty military personnel, retirees, and their dependents in order to conduct medication-related analyses to improve the safety and quality of care in the Military Health System (MHS). Eligible women of reproductive age with at least one pregnancy-related encounter between January 2005 and December 2013 receiving care in the MHS were included in the study population. Building on previously published algorithms, we used pregnancy-related diagnostic and procedure codes, parameterized temporal constraints, and data elements unique to the MHS to identify pregnancies ending in live births, stillbirth, spontaneous abortion, or ectopic pregnancy. Pregnancies ending in live births were matched to presumptive offspring using birth dates and family-based sponsorship identification. Antidepressant and antiepileptic use during pregnancy was evaluated using electronic pharmacy data. Algorithms identified 755,232 women who experienced 1,099,648 complete pregnancies with both pregnancy care encounter and pregnancy outcome. Of the 924,320 live birth pregnancies, 827,753 (90.0%) were matched to offspring. Algorithms also identified 5,663 stillbirths, 11,358 ectopic pregnancies, and 169,665 spontaneous abortions. Among the matched singleton live birth pregnancies, 7.1% of mothers were dispensed an antidepressant at any point during pregnancy, usually a selective serotonin reuptake inhibitor, (75.3%), whereas 1.3% of mothers were dispensed an antiepileptic drug.

    In North America, a high proportion of pregnant women use herbal medications including North American ginseng. This medicinal plant contains high amounts of triterpene saponins (ginsenosides), which are the main bioactive compounds. It is important to assess ginseng's impact on all reproductive functions to ensure the safety of pregnant women and fetuses. In this study, we defined the concentration-responsive effects of North American alcoholic and aqueous ginseng extracts on preimplantation development in vitro and on pregnancy and post-partum development in the mouse. Two-cell mouse embryos were cultured with 5 different concentrations of whole ginseng root extracts, or ginsenosides Rb1, Rg1 and Re alone, a combinatorial ginsenoside solution and a crude polysaccharide fraction solution. Embryonic development and recovery from each treatment was assessed. To investigate the in vivo effects of ginseng extracts, female mice were gavaged with 50[Formula: see text]mg/kg/day, 500[Formula: see text]mg/kg/day or 2000[Formula: see text]mg/kg/day of either extract (treatment) or water (sham) for 2 weeks prior to mating and throughout gestation. Gestation period, litter size, pup growth and pup sex ratio were evaluated. Oral ginseng consumption did not significantly affect fertility or pregnancy in the mouse. High doses of ginseng (2000[Formula: see text]mg/kg/day) decreased maternal weight gain. Direct treatment of preimplantation embryos in vitro demonstrated that ALC and AQ extract treatment reduced development in a concentration responsive manner, while only ALC extract effects were largely reversible. Treatments with individual or combinatorial ginsenosides, or the polysaccharide fraction solution alone did not impair preimplantation development, in vitro. In conclusion, maternal oral consumption of ginseng has little negative impact on pregnancy in the mouse, however, direct exposure to ginseng extract during mouse preimplantation development in vitro is detrimental.

    To describe the development of a questionnaire for assessment of prenatal, birth, and postnatal care (Inventário de Avaliação da Assistência ao Pré-natal, Parto e Puerpério, IAAPPP), which was designed taking into consideration the experience of users of a public obstetric service. This mixed methods research was performed in the city of Caicó, state of Rio Grande do Norte, Brazil. The study consisted of two phases: in phase 1, focal groups were organized with 19 users of the health care system for identification of relevant issues for assessment of the pregnancy-postnatal cycle. The first draft of the questionnaire was also designed and tested for validity with seven of the 19 focal group participants; a second draft was produced and retested. In phase 2, the intra-class correlation coefficient was calculated to determine reproducibility. A pilot test was carried out to determine the applicability of the survey and the final version of the IAAPPP was developed. Based on the focal group discussions, the inventory was organized into four domains: 1) socioeconomic information, 2) obstetric history, 3) description of current obstetric experience and 4) assessment of follow-up. Domains 3 and 4 were subdivided into prenatal care, birthcare, postnatal care, and pregnancy-postnatal cycle. The answers of the women who evaluated the instrument for domain 4 were strongly correlated (>0.8), indicating reproducibility of the IAAPPP. The methodological model allowed us to identify needs and demands of women in the pregnancy-postnatal cycle, and allowed us to design a questionnaire that can be applied to other regions with similar sociocultural characteristics.

  9. Pregnancy weight gain and postpartum loss: avoiding obesity while optimizing the growth and development of the fetus.

    Weight gain during pregnancy may contribute to obesity development. Concerns about possible adverse effects of pregnancy weight gain on later maternal weight and on labor and delivery must be rigorously evaluated in light of possible benefits for fetal growth and development. Birth-weight rises with increased pregnancy weight gain, and perinatal and neonatal mortality fall as birthweight increases in both preterm and term infants. The lowest mortality is observed at 3500 to 4500 g in infants of white women. Although often thought to be at high risk, infants termed "macrosomic" include infants of the lowest mortality rate. Thus, restricting weight gain may be detrimental to the baby. Weight gain that is optimal for the mother and the baby differs according to the mother's prepregnancy weight. Pregnancy weight gain exceeding current recommendations is associated with increases in maternal fat gain, pregnancy complications, and delivery problems and should be discouraged. Postpartum weight loss is essential to prevent permanent weight increase. Smoking cessation during pregnancy, reduced postpartum physical activity, and other lifestyle changes can contribute to increased postpartum weight. Health care providers can help to reduce obesity risk by regularly monitoring women's weight; promoting appropriate prepregnancy weight, pregnancy weight gain, and postpartum weight less; and explicitly encouraging maintenance of an active postpartum lifestyle.

    To develop and test a comprehensive tool for measuring women's attitudes toward the possibility of becoming pregnant. Cross-sectional mixed methods study. Two obstetric/gynecologic (OB/GYN) clinics and one family planning clinic in Baltimore, Maryland. One-hundred thirty (130) nonpregnant, primarily African American women (84%) age 18 to 29. Participants completed a computer-based survey as part of a larger retrospective mixed-methods study. The Attitude Toward Potential Pregnancy Scale (APPS) was assessed using exploratory factor analysis and hypothesis testing. Cronbach's alpha for internal consistency for the APPS was 0.86. Item-total correlations ranged from 0.56 to 0.75. All items loaded on one factor. Support for construct validity was demonstrated using logistic regression, where the odds of being a highly effective contraceptive user decreased by 8% with each one-point increase in score on the APPS (odds ratio = 0.92; confidence interval [0.87, 0.98]). This study provides support for reliability and validity of the APPS. The APPS may be a useful tool for understanding pregnancy attitude in future studies and in clinical practice. Further research is needed to assess the usefulness of the scale with other groups of women, its utility in the clinical practice setting, and its potential predictive validity for unintended pregnancy. © 2014 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Two patients with acute promyelocytic leukemia (APL) in 2nd and 3rd trimester of pregnancy are reported on. Case 1: 38-year-old female consulted our hospital because of bleeding tendency and pancytopenia in April, 1988. She was diagnosed as having APL with disseminated intravascular coagulopathy (DIC) and was found to be in the 14th week of gestation. Combined chemotherapy (BHAC-DMP) including the total dose (440 mg) of daunorubicin (DNR) resulted in intrauterine fetal death at 19 weeks of gestation. The fetus was severely anemic and the bone marrow was hypoplastic. Case 2: A 27-year-old female was diagnosed as having APL with DIC at 29 weeks of gestation. BHAC-DMP including 440 mg DNR achieved complete remission. At 35 weeks of gestation, she delivered a normal infant by Caesarean section. The child had normal hematological findings and showed normal growth. Both cases developed APL accompanied by DIC during pregnancy and were treated with a similar regimen including high dose of anthracyclines. Case 2 treated in the late period of gestation delivered a normal infant, while fetal death resulted in case 1, treated in the early period of gestation. We reviewed the literature regarding chemotherapy using anthracyclines during pregnancy.

    Full Text Available Background : Management of high risk obstetric patients. Aim : The present study was conducted to evaluate the primary causes of the admission of obstetric patients to Intensive Care Unit (ICU, the presence of co-morbid diseases, outcome of such patients, their survival rate as well as the factors which contribute to the maternal mortality. Settings and Design : A retrospective study was conducted in the Department of Obstetrics and Gynaecology and Anaesthesiology/ICU of our Institute. Materials and Methods : Sixty-one obstetric patients, who were admitted to ICU between 20 December 2006 and 31 January 2010, were evaluated for various factors responsible for their admission as well as their outcome. Statistical Analysis : At the end of study, the data were arranged systematically and subjected to statistical analysis using nonparametric tests and P value <0.05 was considered significant. Results : Majority of the 61 patients admitted in ICU were referred from the peripheral health centers, smaller nursing homes/hospitals and some even without proper primary care and mainly comprising uneducated and rural population. Hemorrhage, pregnancy induced hypertension, cardiac diseases, respiratory insufficiency and sepsis were the main causes for admission. A total of 18 patients among 61 died during their ICU stay in the hospital. Conclusions : In the developing countries, high risk pregnancy should be managed at peripheral centers with proper facilities, antenatal visits and timely referral. The intensive care help should be reserved for very high risk pregnancies with co-morbid diseases.

    Full Text Available Lipopolysaccharide (LPS is associated with adverse developmental outcomes including embryonic resorption, fetal death, congenital teratogenesis and fetal growth retardation. Here, we explored the effects of maternal LPS exposure during pregnancy on testicular development, steroidogenesis and spermatogenesis in male offspring. The pregnant mice were intraperitoneally injected with LPS (50 µg/kg daily from gestational day (GD 13 to GD 17. At fetal period, a significant decrease in body weight and abnormal Leydig cell aggregations were observed in males whose mothers were exposed to LPS during pregnancy. At postnatal day (PND 26, anogenital distance (AGD, a sensitive index of altered androgen action, was markedly reduced in male pups whose mothers were exposed to LPS daily from GD13 to GD 17. At PND35, the weight of testes, prostates and seminal vesicles, and serum testosterone (T level were significantly decreased in LPS-treated male pups. At adulthood, the number of sperm was significantly decreased in male offspring whose mothers were exposed to LPS on GD 13-17. Maternal LPS exposure during gestation obviously diminished the percent of seminiferous tubules in stages I-VI, increased the percent of seminiferous tubules in stages IX-XII, and caused massive sloughing of germ cells in seminiferous tubules in mouse testes. Moreover, maternal LPS exposure significantly reduced serum T level in male mice whose mothers were exposed to LPS challenge during pregnancy. Taken together, these results suggest that maternal LPS exposure during pregnancy disrupts T production. The decreased T synthesis might be associated with LPS-induced impairments for spermatogenesis in male offspring.

    Breast cancer incidence rates have declined among older but not younger women; the latter are more likely to be diagnosed with breast cancers carrying a poor prognosis. Epidemiological evidence supports an increase in breast cancer incidence following pregnancy with risk elevated as much as 10 years post-partum. We investigated the association between years since last full-term pregnancy at the time of diagnosis (≤10 or >10 years) and breast tumor subtype in a case series of premenopausal Hispanic women (n = 627). Participants were recruited in the United States, Mexico, and Spain. Cases with known estrogen receptor (ER), progesterone receptor (PR), and HER2 status, with one or more full-term pregnancies ≥1 year prior to diagnosis were eligible for this analysis. Cases were classified into three tumor subtypes according to hormone receptor (HR+ = ER+ and/or PR+; HR- = ER- and PR-) expression and HER2 status: HR+/HER2-, HER2+ (regardless of HR), and triple negative breast cancer. Case-only odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated for HER2+ tumors in reference to HR+/HER2- tumors. Participants were pooled in a mixed-effects logistic regression model with years since pregnancy as a fixed effect and study site as a random effect. When compared to HR+/HER2- cases, women with HER2+ tumors were more likely be diagnosed in the post-partum period of ≤10 years (OR = 1.68; 95 % CI, 1.12-2.52). The effect was present across all source populations and independent of the HR status of the HER2+ tumor. Adjusting for age at diagnosis (≤45 or >45 years) did not materially alter our results (OR = 1.78; 95 % CI, 1.08-2.93). These findings support the novel hypothesis that factors associated with the post-partum breast, possibly hormonal, are involved in the development of HER2+ tumors.

    Since 2004, the American College of Obstetricians and Gynecologists (ACOG) and the Advisory Committee on Immunization Practices (ACIP) have recommended that pregnant women receive the seasonal influenza vaccine, regardless of pregnancy trimester, because of their increased risk for severe complications from influenza. However, the uptake of the influenza vaccine by pregnant women has been low. During the 2009-2010 influenza season, pregnant women were identified as a priority population to receive the influenza A (H1N1) 2009 (2009 H1N1) monovalent vaccine in addition to the seasonal influenza vaccine. In this issue, we highlight information from the 10 states that collected data using the survey administered by the Pregnancy Risk Assessment and Monitoring System (PRAMS) about seasonal vaccine coverage among women with recent live births and reasons for those who chose not to get vaccinated. The combined estimates from PRAMS of influenza vaccination coverage for the 2009-2010 season, which included data from October 2009 to March 2010, from 10 states were 50.7% for seasonal and 46.6% for 2009 H1N1 vaccine among women with recent live births. Among women who did not get vaccinated, reasons varied from worries about the safety of the vaccines for self and baby to not normally getting the vaccination. Further evaluation is needed on ways to increase influenza vaccination among pregnant women, effectively communicate the risk of influenza illness during pregnancy, and address women's concerns about influenza vaccination safety during pregnancy.

    A system to fabricate precise, high aspect ratio polymeric molds by photolithograpic process is described. The molds for producing micro-scale parts from engineering materials by the LIGA process. The invention is a developer system for developing a PMMA photoresist having exposed patterns comprising features having both very small sizes, and very high aspect ratios. The developer system of the present invention comprises a developer tank, an intermediate rinse tank and a final rinse tank, each tank having a source of high frequency sonic agitation, temperature control, and continuous filtration. It has been found that by moving a patterned wafer, through a specific sequence of developer/rinse solutions, where an intermediate rinse solution completes development of those portions of the exposed resist left undeveloped after the development solution, by agitating the solutions with a source of high frequency sonic vibration, and by adjusting and closely controlling the temperatures and continuously filtering and recirculating these solutions, it is possible to maintain the kinetic dissolution of the exposed PMMA polymer as the rate limiting step.

    In recent years, the Zika virus outbreak is ongoing in South-America, followed by increasing morbidity of neurological disorders, including Guillain-Barré syndrome and congenital microcephaly. By the end of March, 2016, thirty-three countries in America were involved, with suspected cases over 190 000. Besides, imported cases have also been reported in Europe and Asia. The correlation between Zika virus infection during the pregnancy and fetal neurogenesis defects raises global severe concern immediately. The potential mechanism can be divided into two pathways:①The blood-placenta barrier may be penetrated by Zika virus and the virus has a characteristic of neurotropism. Subsequently Zika virus can impair neurogenesis directly. ②Zika virus might disrupt fetal neurogenesis indirectly by other mediators, such as fetal inflammatory cytokines or antibodies in cross-immune response. Although the precise mechanism has not been completely elucidated yet, to review the effects of Zika virus infection in pregnancy on fetal neurogenesis promptly as well as the prevention and control of Zika virus outbreak in our country will have both critical clinical and long-term social significances.%近年来,南美洲寨卡病毒(Zika virus)流行,同时该地区吉兰-巴雷综合征(Guillain-Barré syndrome)、新生儿小头畸形发病率明显升高。截至2016年3月,疫情共波及美洲33个国家和地区,超过19万人疑似感染。另外,欧洲、亚洲诸国也均有输入性病例的报道。妊娠寨卡病毒感染与胎儿神经系统发育异常存在着高度的相关性,这已引起了全球范围的密切关注。寨卡病毒影响胎儿神经系统发育的机制可分为直接和间接两条途径:①寨卡病毒可通过血-胎盘屏障,且病毒具有嗜神经性,直接影响胎儿的神经系统发育;②寨卡病毒通过其他介质间接影响胎儿的神经系统发育,如通过胎儿炎症反应介质或免疫交叉反

    2009-06-01

    Full Text Available Abstract Introduction Pulmonary arterial hypertension is a complication of systemic lupus erythematosus. Mortality in pregnant patients with pulmonary arterial hypertension related to connective tissue disease is as high as 56%. The authors report the first case of a successful maternal-fetal outcome in a pregnant patient with systemic lupus erythematosus-associated pulmonary arterial hypertension treated with sildenafil and inhaled iloprost during pregnancy and until several weeks after caesarean section. Case presentation The case presented is of a 29-year-old woman with systemic lupus erythematosus and associated severe pulmonary arterial hypertension. Vasodilator therapy with bosentan and sildenafil, immunosuppressive therapy with prednisone, hydroxychloroquine and azathioprine and oral anticoagulation (phenprocoumon had normalized her right ventricular over right atrial pressure when she was diagnosed in her 5th week of pregnancy. The teratogenic drugs bosentan and phenprocoumon were stopped, the latter replaced by low molecular weight heparin. During the 35th week, a slight increase in pulmonary pressure was found. Therapy with inhaled iloprost was established. A caesarean section was performed in the 37th week and a healthy baby was delivered. The patient remained stable until 11 weeks after delivery, when an increase in right ventricular over right atrial pressure was noted. Bosentan was reintroduced and prednisone and azathioprine doses were increased. The patient has remained stable until the present time. Conclusion Pulmonary arterial hypertension has been considered a contraindication for pregnancy. Novel vasodilator therapy, combined with immunosuppressants in this patient with systemic lupus erythematosus, may "cure" pulmonary arterial hypertension and permit pregnancy with successful outcome. However, postpartum exacerbation of systemic lupus erythematosus and pulmonary arterial hypertension have to be considered.

    Mental disorders are one of the leading contributors to the global burden of disease. The Alberta Pregnancy Outcomes and Nutrition (APrON) study was initiated in 2008 to better understand perinatal environmental impacts on maternal mental health and child development. This pregnancy cohort was established to investigate the relationship between the maternal environment (e.g. nutritional status), maternal mental health status, birth outcomes, and child development. The purpose of this paper is to describe the creation of this longitudinal cohort, the data collection tools and procedures, and the background characteristics of the participants. Participants were pregnant women age 16 or older, their infants and the biological fathers. For the women, data were collected during each trimester of pregnancy and at 3, 6, 12, 24, and 36months after the birth of their infant. Maternal measures included diet, stress, current mental and physical health, health history, and lifestyle. In addition, maternal biological samples (DNA, blood, urine, and spot breast milk samples) were banked. Paternal data included current mental and physical health, health history, lifestyle, and banked DNA samples. For infants, DNA and blood were collected as well as information on health, development and feeding behavior. At the end of recruitment in 2012, the APrON cohort included 2140 women, 2172 infants, and 1417 biological fathers. Descriptive statistics of the cohort, and comparison of women who stayed in the study and those who dropped out are discussed. Findings from the longitudinal cohort may have important implications for health policy and clinical practice. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    To assess the longitudinal change in autonomic nervous system (ANS) activity during pregnancy and the association between anxiety during pregnancy and ANS activity. Pregnant Japanese women with a singleton fetus and normal pregnancy were recruited (n=65). ANS activity and anxiety were measured using a self-rating questionnaire at approximately 20, 30, and 36weeks of gestation. Very low (VLF) and high (HF) frequency bands of heart rate variability spectrums were used. Anxiety was assessed using the Japanese version of the State-Trait Anxiety Inventory. A score of 45 or more on trait-anxiety and the other represent the trait-anxiety group and the non- trait-anxiety group, respectively. The state-anxiety group and the non-state-anxiety group were defined in the same manner. Longitudinal observation of individual pregnant women indicated the significant increasing trend (p=0.002) of VLF power and the significant decreasing trend (p<0.001) of HF power during 20 to 36 gestation weeks. Compared with the non-trait-anxiety group, the trait-anxiety group had significantly lower VLF values at 20 gestational weeks (p=0.033) and had significantly lower HF values at 30 and 36 gestational weeks (p=0.015 and p=0.044, respectively). The increasing rate of VLF from 20 to 36 gestational weeks was higher among the trait-anxiety group. The same associations were observed between the state-anxiety and non-state-anxiety groups at 20 gestational weeks. Anxiety during pregnancy decreased heart rate variability. Anxiety in second trimester pregnancy promoted a subsequent increase in sympathetic activity. Copyright © 2017 Elsevier Inc. All rights reserved.

    Nowadays, most of the young women affected by Systemic Lupus Erythematosus (SLE) can carry out one or more pregnancies thanks to the improvement in treatment and the consequent reduction in morbidity and mortality. Pregnancy outcome in these women has also greatly improved in the last decades. A correct timing for pregnancy (tailored on disease activity and established during a preconception counselling), together with a tight monitoring during the three trimesters and the post-partum period (to timely identify and treat possible obstetric complications or maternal disease flares), as well as the concept of multidisciplinary management, are currently milestones of the management of pregnancy in SLE patients. Nevertheless, the increasing knowledge on the compatibility of drugs with pregnancy has allowed a better treatment of these patients, by choosing medications that control maternal disease activity without harming the foetus. However, particular attention and strict monitoring should be dedicated to SLE pregnant women in particular clinical settings: patients with lupus nephritis and patients with aPL positivity or Antiphospholipid syndrome, who are at higher risk for maternal and foetal complications, but also patients with anti-Ro/SSA and/or anti-La/SSB antibodies, because of the risk of neonatal lupus. A discussion on family planning, as well as counselling on contraception, should be part of the everyday-practice for physicians caring for SLE women during their reproductive age. Another issue is the possible reduction of fertility in these women, that can be due to different reasons. Consequently, the request for assisted reproduction techniques has been increasing in the last years, so that rheumatologists and gynaecologists should be prepared to counsel SLE patients also in this particular setting.

    Full Text Available The skin changes in pregnancy can be either physiological (hormonal, changes in pre-existing skin diseases or development of new pregnancy specific dermatoses. Pregnancy-specific skin dermatoses include an ill-defined heterogeneous group of pruritic skin eruptions which are seen only in pregnancy. These include atopic eruption of pregnancy, polymorphic eruption of pregnancy, pemphigoid gestationis and intrahepatic cholestasis of pregnancy. Atopic eruption of pregnancy is the most common of these disorders. Most skin eruptions resolve postpartum and require only symptomatic treatment. Antepartum surveillance is recommended for patients with pemphigoid gestationis and intrahepatic cholestasis of pregnancy as they carry fetal risk. This article deals with the classification, clinical features and treatment of the specific dermatoses of pregnancy.

    Concerns about the increasing rates of obesity in developing countries have led many policy makers to question the impacts of maternal and early child nutrition on risk of later obesity. The purposes of the review are to summarise the studies on the associations between nutrition during pregnancy and infant feeding practices with later obesity from childhood through adulthood and to identify potential ways for preventing obesity in developing countries. As few studies were identified in developing countries, key studies in developed countries were included in the review. Poor prenatal dietary intakes of energy, protein and micronutrients were shown to be associated with increased risk of adult obesity in offspring. Female offspring seem to be more vulnerable than male offspring when their mothers receive insufficient energy during pregnancy. By influencing birthweight, optimal prenatal nutrition might reduce the risk of obesity in adults. While normal birthweights (2500-3999 g) were associated with higher body mass index (BMI) as adults, they generally were associated with higher fat-free mass and lower fat mass compared with low birthweights (obesity in adults. Breastfeeding and timely introduction of complementary foods were shown to protect against obesity later in life in observational studies. High-protein intake during early childhood however was associated with higher body fat mass and obesity in adulthood. In developed countries, increased weight gain during the first 2 years of life was associated with a higher BMI in adulthood. However, recent studies in developing countries showed that higher BMI was more related to greater lean body mass than fat mass. It appears that increased length at 2 years of age was positively associated with height, weight and fat-free mass, and was only weakly associated with fat mass. The protective associations between breastfeeding and obesity may differ in developing countries compared to developed countries because many

    The purpose of this study was to establish a possible correlation between systemic hypermobility and temporomandibular hypermobility during pregnancy. One hundred (100) healthy pregnant women were evaluated: 7% in the first trimester (1T), 38% in the second trimester (2T), and 55% in the third trimester (3T) of gestation. In the series, the authors analyzed systemic joint hypermobility (SJH), range of mandibular movement (MMR), head and shoulder posture, head lateralization, and the presence of noise, pain, and parafunction in the temporomandibular joint. They observed that pain is present to a mild degree mostly in the head and ears of all pregnant women who presented with pain. Most of the subjects had some type of parafunction, but only 42.8% had noises. Mild SJH was seen in 50% of the 2T and 3T subjects, and in 28.5% of 1T subjects. Mild mandibular hypermobility was found for jaw opening (46%) and lateralization to the right (44%) or to the left (46%). Most of the subjects had hypomobility for jaw protrusion and retraction. The subjects had head protrusion and anterior posture as a result of the change in their center of gravity brought about by pregnancy. The authors found no association between systemic joint hypermobility (SJH) and temporomandibular hypermobility, although hormonal changes and complex factors during pregnancy may represent a risk factor for both types of mobility change.

    Currently in the UK, there is no absolute guidance about alcohol consumption in pregnancy. The guidance for drinking during pregnancy is one or two units of alcohol one or two times weekly, but conservative advice is to abstain as a cautionary measure. Despite the lack of consensus about the safe levels of alcohol consumption in pregnancy, there is increasing evidence of the impact of alcohol on the developing central nervous system. This article explores the evidence regarding alcohol consumption and its effects on the developing fetal central nervous system.

    The aim of this study was to investigate the influence of progesterone (P4) on adiponectin system genes and protein expression in the endometrium and myometrium during early gestation. Twenty-five gilts were assigned to 1 of 5 groups ( = 5): d 10 to 11 (embryo migration), 12 to 13 (maternal recognition of pregnancy), 15 to 16 (implantation), and 27 to 28 (end of implantation) of pregnancy and d 10 to 11 of the cycle (fully active corpora lutea, corresponding to the corpora lutea activity during gestation). The endometrial and myometrial tissues were cut into 100 mg slices, treated with P4 (10, 100, 1000 nM) and incubated for 24 h. Gene expression was analyzed by the real-time PCR method. Adiponectin secretion was determined by ELISA. Receptor protein content was defined using Western Blot analysis. In the endometrium, on d 10 to 11 of pregnancy, P4 stimulated adiponectin protein secretion. On those days, P4 enhanced adiponectin receptor type 1 () and type 2 () gene expression but inhibited both receptors' protein content. On d 12 to 13 of pregnancy, P4 inhibited adiponectin gene expression. During those period, P4 enhanced gene expression but suppressed both receptors' protein content. On d 15 to 16 of gestation, P4 increased adiponectin gene expression but inhibited the protein secretion. During those days, P4 suppressed gene expression and enhanced AdipoR2 protein content. On d 27 to 28 of gestation, P4 enhanced gene and AdipoR1 protein expression ( adiponectin and genes and AdipoR1 protein expression but decreased AdipoR2 protein content. On d 15 to 16 of gestation, P4 inhibited adiponectin gene expression. On those days, P4 enhanced gene and protein expression. On d 27 to 28 of gestation, P4 decreased adiponectin gene expression. On those days, P4 increased the myometrial AdipoR2 protein concentration and decreased gene protein expression ( adiponectin system in the porcine uterus during early pregnancy, which may suggest the involvement of this adipokine in

    Full Text Available In case of pregnancies, one of the most common pathological conditions in internal medicine is aneamia with iron-deficiency. Furthermore, iron deficiency may also affect the mother and the fetus negatively. We wanted to find out which group of expectant mothers are mostly affected, which factors influence the development of aneamia. It was also observable in the case of those living at higher living standards that they take fetus-protecting vitamins with a significantly higher frequency before the pregnancy than those living at lower living standards. According to our research data, 67% of the sample developed aneamia. In our research the risk group consisted of young, vegetarian expectant mothers with low education and the multiparas. After conception, the timing of gynaecological consultation was appropriate and the majority of the sample had a clear idea of the ways of preventing aneamia. However, prevention was only realized in practice - based on the criteria - only with a frequency of 12%. It would be important to consciously plan pregnancy. After taking expectant mothers into care, they should - as soon as possible - be screened for the deficiency and in need, supplements should be started. Risk groups should be given greater attention. In their case, a routine supplement of iron would be desirable even before the development of a deficiency. During pregnancy care, awareness must be raised and an iron-rich diet should be established at the beginning. Beyond these, general practitioner, health visitors have the opportunity - through the close relationship with the expectant mothers - to control laboratory tests, provide appropriate information, recommend vitamin preparations as well as check taken medications.

    During Pregnancy, heart develops physiological left ventricular hypertrophy as a result of the natural volume overload. Previously we have characterized the molecular and functional signature of heart hypertrophy during pregnancy. Cardiac hypertrophy during pregnancy is a complex process that involves many changes including in the signalling pathways, composition of extracellular matrix as well as the levels of sex hormones. This review summarises the recent advances and the new frontiers in the context of heart hypertrophy during pregnancy. In particular we focus on structural and extracellular matrix remodelling as well as signalling pathways in pregnancy-induced physiological heart hypertrophy. Emerging evidence shows that various microRNAs modulate key components of hypertrophy, therefore the role of microRNAs in the regulation of gene expression in pregnancy induced hypertrophy is also discussed. We also review the role of ubiquitin proteasome system, the major machinery for the degradation of damaged and misfolded proteins, in heart hypertrophy. The role of sex hormones in particular estrogen in cardiac remodeling during pregnancy is also discussed. We also review pregnancy-induced cardiovascular complications such as peripartum cardiomyopathy and pre-eclampsia and how the knowledge from the animal studies may help us to develop new therapeutic strategies for better treatment of cardiovascular diseases during pregnancy. Special emphasis has to be given to the guidelines on disease management in pregnancy.

    An excessive production of reactive oxygen substances (ROS) and reduced antioxidant defence systems resulting from electromagnetic radiation (EMR) exposure may lead to oxidative brain and liver damage and degradation of membranes during pregnancy and development of rat pups. We aimed to investigate the effects of Wi-Fi-induced EMR on the brain and liver antioxidant redox systems in the rat during pregnancy and development. Sixteen pregnant rats and their 48 newborns were equally divided into control and EMR groups. The EMR groups were exposed to 2.45GHz EMR (1h/day for 5 days/week) from pregnancy to 3 weeks of age. Brain cortex and liver samples were taken from the newborns between the first and third weeks. In the EMR groups, lipid peroxidation levels in the brain and liver were increased following EMR exposure; however, the glutathione peroxidase (GSH-Px) activity, and vitamin A, vitamin E and β-carotene concentrations were decreased in the brain and liver. Glutathione (GSH) and vitamin C concentrations in the brain were also lower in the EMR groups than in the controls; however, their concentrations did not change in the liver. In conclusion, Wi-Fi-induced oxidative stress in the brain and liver of developing rats was the result of reduced GSH-Px, GSH and antioxidant vitamin concentrations. Moreover, the brain seemed to be more sensitive to oxidative injury compared to the liver in the development of newborns.

    In the course of scleroderma numerous complications may occur caused by the endothelial vessel changes and organs' fibrosis. Pregnancy itself is associated with increased immunization caused by the microchimerism phenomenon. Pregnancy may be associated with increased dyspnea, hypertension, gastroesophageal reflux disease (GERD), renal complications and mother pre-eclampsia. In turn, the most common disorders of the fetus include low birth weight, premature delivery and heart block. The occurrence of organ complications in the mother needs urgent gynecological and rheumatologic care, which often requires the consultation of pulmonologist, cardiologist, nephrologists and gastroenterologist. In case of the development of fetal abnormalities neonatal care is needed. Considering the possible complications of mother and child in the course of scleroderma, pregnancy should be planned in the most optimal time and its course should be monitor, what increases the safety and positive outcome for mother and fetus. In case of complications, early interdisciplinary intervention prevents their development and reduces the risk of serious and prolonged health consequences for both mother and child.

    Treatment of chronic myeloid leukemia (CML) is challenging in patients who want to conceive. We followed 809 patients with CML treated with imatinib mesylate (IM). We observed outcomes in 90 pregnancies from 61 patients (21 females, 40 males) who conceived while on IM. Information was obtained on duration of exposure to IM, pregnancy termination and congenital abnormalities. Hematologic and cytogenetic responses were also recorded. Twenty-eight pregnancies occurred among females, while 62 were reported from male patients. Among female patients, 19 (67.9%) pregnancies were uneventful while six (21.4%) ended in adverse events. Only 12 (57%) females reported their pregnancies. Three (4.4%) adverse events were reported from male patients. Pregnancy is an important part of life in our young patients due to cultural and societal pressures. It is paramount to counsel pregnant patients to switch to drugs with no adverse effect on the developing fetus. However, lack of communication is a major factor preventing physicians from counseling patients about conception.

    Full Text Available Abstract Background The development of the in vitro cell culture model has greatly facilitated the ability to study gene expression and regulation within human tissues. Within the human uterus, the upper (fundal segment and the lower segment may provide distinct functions throughout pregnancy and during labour. We have established primary cultured human myometrial cells, isolated from both upper and lower segment regions of the pregnant human uterus, and validated them for the purpose of studying human pregnancy and labour. The specific objectives of this study were to monitor the viability and characterize the expression profile using selected cellular, contractile and pregnancy associated markers in the primary cultured human myometrial cells. Labour has been described as an inflammatory process; therefore, the ability of these cells to respond to an inflammatory stimulus was also investigated. Methods Myometrial cells isolated from paired upper segment (US and lower segment (LS biopsies, obtained from women undergoing Caesarean section deliveries at term prior to the onset of labour, were used to identify expression of; α smooth muscle actin, calponin, caldesmon, connexin 43, cyclo-oxygenase-2 (COX-2, oxytocin receptor, tropomyosin and vimentin, by RT-PCR and/or immunocytochemistry. Interleukin (IL-1β was used to treat cells, subsequently expression of COX-2 mRNA and release of interleukin-8 (CXCL8, were measured. ANOVA followed by Bonferroni’s multiple comparisons test was performed. Results We demonstrate that US and LS human myometrial cells stably express all markers examined to at least passage ten (p10. Connexin 43, COX-2 and vimentin mRNA expression were significantly higher in LS cells compared to US cells. Both cell populations respond to IL-1β, demonstrated by a robust release of CXCL8 and increased expression of COX-2 mRNA from passage one (p1 through to p10. Conclusions Isolated primary myometrial cells maintain expression of

The physiological changes in the maternal immune system during a pregnancy may influence the development of this and other autoimmune diseases. Furthermore, pregnancy-associated physiological changes influence the synthesis and metabolism of thyroid hormones and challenge the interpretation of thyroid function tests in pregnancy. Thyroid hormones are crucial regulators of early development and play an important role in the maintenance of a normal pregnancy and in the development of the fetus, particularly the fetal brain. Untreated or inadequately treated hyperthyroidism is associated with pregnancy complications and may even program the fetus to long-term development of disease. Thus, hyperthyroidism in pregnant women should be carefully managed and controlled, and proper management involves different medical specialties. The treatment of choice in pregnancy is antithyroid drugs (ATDs. These drugs are effective in the control of maternal hyperthyroidism, but they all cross the placenta, and so need careful management and control during the second half of pregnancy considering the risk of fetal hyper- or hypothyroidism. An important aspect in the early pregnancy is that the predominant side effect to the use of ATDs in weeks 6–10 of pregnancy is birth defects that may develop after exposure to available types of ATDs and may be severe. This review focuses on four current perspectives in the management of overt hyperthyroidism in pregnancy, including the etiology and incidence of the disease, how the diagnosis is made, the

    Spent fuel inventories to be disposed of finally and design base spent fuel were determined. Technical and safety criteria for a geological repository system in Korea were established. Based on the properties of spent PWR and CANDU fuels, seven repository alternatives were developed and the most promising repository option was selected by the pair-wise comparison method from the technology point of view. With this option preliminary conceptual design studies were carried out. Several module, e.g., gap module, congruent release module were developed for the overall assessment code MASCOT-K. The prominent overseas databases such as OECD/NEA FEP list were are fully reviewed and then screened to identify the feasible ones to reflect the Korean geo-hydrological conditions. In addition to this the well known scenario development methods such as PID, RES were reviewed. To confirm the radiological safety of the proposed KAERI repository concept the preliminary PA was pursued. Thermo-hydro-mechanical analysis for the near field of repository were performed to verify thermal and mechanical stability for KAERI repository system. The requirements of buffer material were analyzed, and based on the results, the quantitative functional criteria for buffer material were established. The hydraulic and swelling property, mechanical properties, and thermal conductivity, the organic carbon content, and the evolution of pore water chemistry were investigated. Based on the results, the candidate buffer material was selected.

    Orexin A and B are hypothalamic peptides derived from the prepro-orexin (PPO) precursor. Orexins stimulate food intake and arousal. Those peptides bind and activate two G protein-coupled receptors: orexin receptor 1 (OX1R) and orexin receptor 2 (OX2R). Numerous authors have suggested that orexins play an important role in the regulation of the reproductive functions. The objective of the present study was to analyse the presence of and changes in the gene and protein expression pattern of the orexin system in the porcine uterus, conceptus and trophoblast (chorioallantois) during early pregnancy. In the endometrium, the highest PPO and OX1R gene expression was detected on days 15 to 16 of gestation. The OX2R mRNA content in the endometrium was higher on days 10 to 11 and 15 to 16 than on days 12 to 13 and 27 to 28. In the trophoblasts, PPO gene expression was higher on days 30 to 32 than on days 27 to 28. The highest PPO protein content in the endometrium was noted on days 12 to 13. The highest OX1R protein content in the endometrium was detected on days 10 to 11, whereas OX2R protein on days 15 to 16. In the trophoblasts, PPO and OX1R protein levels were more pronounced on days 27 to 28 than on days 30 to 32, but OX2R expression was higher on days 30 to 32. The expression of PPO, OX1R and OX2R was different in the conceptuses and trophoblasts during early pregnancy. Local orexin production and the presence of the specific orexin receptors suggest that the orexin system may participate in the control of porcine reproductive functions by exerting endocrine and auto/paracrine effects on the uterus, conceptuses and trophoblasts during early pregnancy. This study provides the first evidence for the presence of orexins and their receptors in the uteri, conceptuses and trophoblasts in pigs during early pregnancy. The local orexin system is dependent on the stage of pregnancy.

    This study evaluated the reproductive effects of fluoxetine exposure in utero and during lactation on pregnancy outcomes and the sexual development of offspring. Pregnant Wistar rats were treated daily with fluoxetine (0.4, 1.7 and 17 mg/kg/day) or distilled water by gavage from gestation day (GD) 7 to lactation day (LD) 21. A significant reduction in maternal body weight was observed during pregnancy and lactation in dams exposed to 17 mg/kg fluoxetine. Hormone analysis revealed an increase in progestagen and glucocorticoid metabolites on GD 15 and oestrogen and progestagen metabolites on LD 7 in dams treated with 17 mg/kg fluoxetine. Oestrogen metabolites also were increased on LD 7 in dams treated with 0.4 mg/kg fluoxetine. Besides that, an increase in the weight of the adrenal glands and a reduction in uterine weight in dams exposed to highest dose of fluoxetine were observed. Finally, pup birthweight and the viability and weaning indices also were reduced in animals exposed to 17 mg/kg fluoxetine. Overall, maternal hormonal changes were only observed at the highest dose tested, which also induced maternal and foetal toxicity. No significant changes were seen in dams or offspring exposed to therapeutic-like doses.

    Preeclampsia (PE) is a pregnancy-specific disorder, defined as new onset of maternal hypertension and proteinuria after 20 weeks of gestation. Our earlier study has shown increased maternal oxidative stress at delivery to be associated with poor birth outcome in PE. However, these results were observed when the pathology had progressed and may have been secondary to the effects of the disorder. To understand the role of antioxidant defense mechanisms in PE right from early pregnancy, in this prospective study, we measured malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione (GSH) concentrations in maternal blood at 3 time-points of gestation [16-20 weeks (T1), 26-30 weeks (T2), at delivery (T3)] and in cord blood. Gene expression of SOD and GPx and protein levels of endothelial nitric oxide synthase (eNOS) enzyme were also analyzed in the placenta. MDA levels were higher at T1 (p stress right from 16 to 20 weeks of gestation. This may alter placental development and lead to fetal programming of adult non-communicable disease in the offspring.

    Mefloquine (MQ) is a potent effective antimalarial drug against multiple drug-resistant Plasmodium falciparum. It has been proved that MQ can be given safely during the second and third trimesters. However, there is very limited information on the drug safety during the first trimester. The aim of the present work was to investigate the embryotoxicity and teratogenicity of MQ during critical periods of early development. Wistar rats were orally administered with a single dose of MQ (45 mg/kg bwt or 187 mg/kg bwt) on the 1st, 6th or 13th days of pregnancy. Cyclophosphamide (CPA) was chosen as a positive control. On the 21st day of gestation, standard parameters of reproductive performance and fetal examination were estimated. Malondialdehyde (MDA) level, glutathione reductase activity and glutathione (GSH) content were evaluated in placenta and liver homogenates of mothers and fetuses. The results indicated that MQ did not adversely affect the number of implantation, resorption, litter size and fetal body weight and length. Only groups treated with MQ on the 1st day of gestation exhibited significant decrease in fetal body weight. Examination of fetuses for external, visceral and skeletal changes showed minimal variations involving extension of lateral brain ventricles and renal pelvis and signs of delayed ossification. These variations were accompanied with significant elevation of MDA level and reduction of GSH content of fetal liver. Prenatal exposure to MQ at early pregnancy did not cause any embryolethal or teratogenic effect. It could slightly exacerbate minor variations.

  14. Thyroid disease and pregnancy.

    Thyroid disease is common in younger women and may be a factor in reproductive dysfunction. This probably only applies to severe cases of hyper- or hypothyroidism. Once adequately treated, neither of these disorders significantly impacts on fertility. The key is to recognize and to treat thyroid disorders in the reproductive-age woman before conception. Thyroxine therapy and even antithyroid drug therapy should be continued during pregnancy as necessary. Pregnancy is a euthyroid state that is normally maintained by complex changes in thyroid physiology. The fetal and neonatal hypothalamic-pituitary-thyroid system develops independently, but it may be influenced by thyroid disease in the mother. Early pregnancy is characterized by an increase in maternal T4 secretion stimulated by hCG and an increase in TBG, resulting in the elevated total serum T4 in pregnancy. The debate continues as to whether maternal T4 is important in early or late fetal brain development. If so, the physiologic changes in thyroid hormone secretion and transport in early pregnancy would help to ensure that a sufficient amount of thyroid hormone was available. There is new evidence in human subjects that substantial maternal T4 can cross the placenta during pregnancy, and this may be particularly important when fetal thyroid function is compromised as a result of congenital hypothyroidism. Maternal and fetal/neonatal outcomes in pregnancy are adversely affected if severe hypothyroidism is undiagnosed or inadequately treated. Thyroid function tests should be obtained during gestation in women taking T4 and appropriate dose adjustments should be made for TSH levels outside a normal range. The TSH-receptor blocking antibodies from the mother are a recognized cause of congenital hypothyroidism in the fetus and neonate that can be permanent or transient. If neonatal hypothyroidism is detected through neonatal screening programs, and prompt and adequate T4 replacement therapy is instituted as soon as

    Psychological stress at work is a rising problem in Denmark. Nearly one third of the women reported in 2005 that they had difficulties completing their work tasks, and 17 % found that they had only limited or no influence on their work tasks. The corresponding numbers for 1987 were 18.3 % and 16 %, respectively. Work-related stress shortens the life expectancy and reduces the number of years without prolonged disease. For the society work-related stress amounts to more than 30,000 hospital admissions each year, half a million extra days on sick-leave for women, 500,000 contacts to general practitioners, 1600 early retirements for women, and an overuse of the health-care system. With the second highest employment rate in Europe for women - and many of them in the childbearing age - effects of psychological stress at work may extend beyond the exposed individual and affect pregnancy, birth and health of the child. Few studies on job stress relative to pregnancy have been carried out, but both animal and epidemiological studies have shown effect of exposure to stressful conditions during pregnancy and adverse effects on the offspring. The specific aims for the three studies included in this thesis were to investigate the association between maternal psychosocial job strain during pregnancy, measured as high demands and low control and the risk of: - Having a child born preterm or with low or high birth weight relative to gestational week (paper I + II) - Congenital malformations in offspring (paper III) - Asthma and atopic dermatitis in the children (paper IV). Furthermore, it was also the ambition to maximize and secure the quality of research and integrity of the data used by documenting the methods in a protocol that described the analyses before they were done and to keep transparency in the methods used following good epidemiological practices (GEP) for occupational and environmental epidemiological research. All analyses in this thesis are based on information

    We developed a pilot evidence-based prenatal educational intervention to increase knowledge of neonatal abstinence syndrome (NAS) and early parenting skills for women with opiate dependency who enrolled in a pregnancy buprenorphine clinic. We developed, implemented, and tested modules regarding expectations during newborn hospitalization for observation or treatment of NAS and regarding evidence-based parenting skills in response to NAS behaviors. Testing evaluated baseline knowledge of early parenting skills with newborns at risk for NAS and change from baseline after the educational intervention. No statistically significant difference in composite knowledge scores was observed. A brief survey completed by the participants postpartum affirmed the perception of women that the educational intervention effectively prepared them for the early postpartum period while their newborns were hospitalized.

    During pregnancy and postpartum rats experience a wide variety of behavioural changes. Since the somatostatinergic system has been implicated in the control of some of these changes, the present study examined somatostatin (SS) content and specific binding in the frontoparietal cortex and hippocampus of non-pregnant, pregnant (17 to 18 days), parturition and postpartum (10 and 30 days) rats as well as in ovariectomized rats which were or were not treated with estradiol valerianate. The content of somatostatin-like immunoreactivity (SSLI) was increased at 17 days of pregnancy in frontoparietal cortex and decreased at parturition and 10 days postpartum in that region and the hippocampus under study when compared with SSLI levels in non-pregnant rats. At 30 days postpartum the SSLI content returned to non-pregnant values in both brain regions. Scatchard analysis showed that the decrease in [125I]Tyr11-SS binding observed at 17 days of pregnancy in the frontoparietal cortex was due to the decrease in the number of SS receptors. In contrast, on the day of delivery the number of SS receptors in the same brain region increased. The affinity of the SS receptors was consistently unchanged in pregnant and non-pregnant rats in both regions. At 10 days postpartum the value of specific binding of the tracer to SS receptors in the frontoparietal cortex was not significantly different from that in the non-pregnant rats, although the actual number of receptors was slightly higher. Pregnancy did not change SS binding in the hippocampus.(ABSTRACT TRUNCATED AT 250 WORDS)

    Secondary lymphoid organs form in utero through an inherited and well-established developmental program. However, maternal non-heritable features can have a major impact on the gene expression of the embryo, hence influencing the future health of the offspring. Recently, maternal retinoids were shown to regulate the formation of immune structures, shedding light on the role of maternal nutrition in the genetic signature of emergent immune cells. Here we highlight evidence showing how the maternal diet influences the establishment of the immune system, and we also discuss how unbalanced maternal diets may set the response to infection and vaccination in the progeny.

    Studies examining hormones throughout pregnancy and lactation in women have been limited to single, or a few repeated, short-term measures of endocrine activity. Furthermore, potential differences in chronic hormonal changes across pregnancy/lactation between first-time and experienced mothers are not well understood, especially as they relate to infant development. Hormone concentrations in hair provide long-term assessments of hormone production, and studying these measures in non-human primates allows for repeated sampling under controlled conditions that are difficult to achieve in humans. We studied hormonal profiles in the hair of 26 female rhesus monkeys (Macaca mulatta, n=12 primiparous), to determine the influences of parity on chronic levels of cortisol (hair cortisol concentration, HCC) and progesterone (hair progesterone concentration, HPC) during early- to mid-pregnancy (PREG1), in late pregnancy/early lactation (PREG2/LACT1), and in peak lactation (LACT2). We also assessed infants' neurobehavioral development across the first month of life. After controlling for age and stage of pregnancy at the first hair sampling period, we found that HCCs overall peaked in PREG2/LACT1 (p=0.02), but only in primiparous monkeys (ppregnancy and lactation for all monkeys (phormonal profiles and infant development. These effects may, in part, reflect differential reproductive and maternal effort in mothers with varied caretaking experience. In addition, infant exposure to relatively higher levels of maternal cortisol during the late fetal and early postnatal periods is predictive of poorer developmental outcomes.

    A new fine coal dewatering technology has been developed and tested in the present work. The work was funded by the Solid Fuels and Feedstocks Grand Challenge PRDA. The objective of this program was to 'develop innovative technical approaches to ensure a continued supply of environmentally sound solid fuels for existing and future combustion systems with minimal incremental fuel cost.' Specifically, this solicitation is aimed at developing technologies that can (i) improve the efficiency or economics of the recovery of carbon when beneficiating fine coal from both current production and existing coal slurry impoundments and (ii) assist in the greater utilization of coal fines by improving the handling characteristics of fine coal via dewatering and/or reconstitution. The results of the test work conducted during Phase I of the current project demonstrated that the new dewatering technologies can substantially reduce the moisture from fine coal, while the test work conducted during Phase II successfully demonstrated the commercial viability of this technology. It is believed that availability of such efficient and affordable dewatering technology is essential to meeting the DOE's objectives.

METHODS: Medical charts of 155 consecutive PRL inpatients were systematically reviewed, including demographic data, clinical features, laboratory findings, treatment, complications, and outcome. RESULTS: PRL cases were divided into active (a-PRL (n = 82, 53.0% and stable lupus (s-PRL (n = 73, 47.0%. Compared with nonpregnant active female systemic lupus erythematosus (SLE patients, a-PRL including new-onset lupus (n-PRL and flare lupus (f-PRL (n = 41 respectively, had a higher incidence of renal and hematological involvement but less mucocutaneous and musculoskeletal involvement (p<0.05. The incidence of preeclampsia/eclampsia, fetal loss, and preterm birth were significantly higher in a-PRL than in s-PRL (p<0.05. Despite receiving a more vigorous glucocorticoid treatment, a-PRL mothers had a poorer prognosis (p<0.001. Five (6.1% of them died and 13 (15.9% developed severe irreversible organ failure, whereas none of these events was observed in the s-PRL group. Multivariate logistic analysis indicated that a history of lupus flares and serological activity (hypocomplementemia and/or anti-dsDNA positivity at the time of conception were associated with lupus flares in PRL mothers. CONCLUSIONS: SLE patients with a flare history and serological activity at the time of conception were at an increased risk of disease flares during pregnancy and puerperium. a-PRL patients were more prone to renal and hematological involvement, pregnancy complications, and a poorer prognosis despite more vigorous glucocorticoid treatment.

    Teen pregnancy is a social problem not resolved in developing and some developed countries. Adolescent fecundity has become the most exact bio-demographic and health indicator of development. In developing countries that are expected to follow the sexual behaviour patterns of developed countries, without offering the levels of education and services for adolescents, the consequences will be adolescent fecundity and STI prevalence increase. The ignorance about sexuality and reproduction both in parents, teachers and adolescents increases the early initiation of coital relations and of unwanted pregnancies. Extreme poverty and being the son or daughter of an adolescent mother are risk factors of repeating the early pregnancy model. The application of predictive risk criteria in pregnant adolescents to facilitate the rational use of Health Services to diminish the maternal and perinatal mortality is discussed as well as the social factors associated with adolescent pregnancy as socioeconomic levels, structure - types and characteristics of the family, early leaving school, schooling after delivery, female employment, lack of sexual education, parental and family attitudes in different periods of adolescent pregnancy, adolescent decisions on pregnancy and children, unstable partner relationship and adoption as an option. Social consequences are analyzed as: incomplete education, more numerous families, difficulties in maternal role, abandonment by the partner, fewer possibilities of having a stable, qualified and well-paid job, greater difficulty in improving their socioeconomic level and less probability of social advancement, lack of protection of the recognition of the child. Finally, based on evidence, some measures that can reduce adverse consequences on adolescent mothers, fathers and their children are suggested. Copyright © 2012 S. Karger AG, Basel.

  7. Prenatal Alcohol Exposure and the Developing Immune System.

    Science.gov (United States)

    Gauthier, Theresa W

    2015-01-01

    Evidence from research in humans and animals suggest that ingesting alcohol during pregnancy can disrupt the fetal immune system and result in an increased risk of infections and disease in newborns that may persist throughout life. Alcohol may have indirect effects on the immune system by increasing the risk of premature birth, which itself is a risk factor for immune-related problems. Animal studies suggest that alcohol exposure directly disrupts the developing immune system. A comprehensive knowledge of the mechanisms underlying alcohol's effects on the developing immune system only will become clear once researchers establish improved methods for identifying newborns exposed to alcohol in utero.

    Though there were many studies assessing the relationship between maternal thyroxine levels during pregnancy and cognitive development in children, there was still lack of evidence for the association from a comprehensive assessment of published data. To get a more comprehensive estimate of the influence of low maternal thyroxine levels on cognitive function, a meta-analysis of prospective cohort studies was performed. Two electronic databases, MEDLINE and EMBASE, were searched for relevant prospective cohort studies. Relative risks (RR) with 95% confidence intervals (95% CI) were pooled using random-effect model of meta-analysis to assess the risk of delayed cognitive development in children. Seven prospective cohort studies with a total of 8273 mother-child pairs were included into the meta-analysis. There was obvious between-study heterogeneity in the meta-analysis (I(2) = 69.6%). Meta-analysis of using random-effect model showed that low maternal thyroxine level was significantly associated with a threefold risk of delayed cognitive development in children (random RR = 3.08, 95% CI 1.83-5.18, P cognitive development in children (random RR = 3.76, 95% CI 2.14-6.58, P cognitive development in children. Low maternal thyroxine level is significantly associated with a threefold risk of delayed cognitive development in children.

  11. Increased risk for the development of preeclampsia in obese pregnancies: weighing in on the mechanisms

    Science.gov (United States)

    Spradley, Frank T.; Palei, Ana C.

    2015-01-01

    Preeclampsia (PE) is a pregnancy-specific disorder typically presenting as new-onset hypertension and proteinuria. While numerous epidemiological studies have demonstrated that obesity increases the risk of PE, the mechanisms have yet to be fully elucidated. Growing evidence from animal and human studies implicate placental ischemia in the etiology of this maternal syndrome. It is thought that placental ischemia is brought about by dysfunctional cytotrophoblast migration and invasion into the uterus and subsequent lack of spiral arteriole widening and placental perfusion. Placental ischemia/hypoxia stimulates the release of soluble placental factors into the maternal circulation where they cause endothelial dysfunction, particularly in the kidney, to elicit the clinical manifestations of PE. The most recognized of these factors are the anti-angiogenic sFlt-1 and pro-inflammatory TNF-α and AT1-AA, which promote endothelial dysfunction by reducing levels of the provasodilator nitric oxide and stimulating production of the potent vasoconstrictor endothelin-1 and reactive oxygen species. We hypothesize that obesity-related metabolic factors increase the risk for developing PE by impacting various stages in the pathogenesis of PE, namely, 1) cytotrophoblast migration and placental ischemia; 2) release of soluble placental factors into the maternal circulation; and 3) maternal endothelial and vascular dysfunction. This review will summarize the current experimental evidence supporting the concept that obesity and metabolic factors like lipids, insulin, glucose, and leptin affect placental function and increase the risk for developing hypertension in pregnancy by reducing placental perfusion; enhancing placental release of soluble factors; and by increasing the sensitivity of the maternal vasculature to placental ischemia-induced soluble factors.

  15. Systemic lupus erythematosus and pregnancy: clinical evolution, maternal and perinatal outcomes and placental findings

    Directory of Open Access Journals (Sweden)

    Fernanda Garanhani de Castro Surita

    2007-03-01

    Full Text Available CONTEXT AND OBJECTIVE: Systemic lupus erythematosus is a chronic disease that is more frequent in women of reproductive age. The relationship between lupus and pregnancy is problematic: maternal and fetal outcomes are worse than in the general population, and the management of flare-ups is difficult during this period. The aim here was to compare the outcomes of 76 pregnancies in 67 women with lupus, according to the occurrence or absence of flare-ups. DESIGN AND SETTING: An observational cohort clinical study evaluating the evolution of pregnant women with lupus who were receiving care at the prenatal outpatient clinic, Centro de Atenção Integral à Saúde da Mulher, Universidade Estadual de Campinas (CAISM/Unicamp, between 1995 and 2002. METHODS: Data were collected on a precoded form. The women were divided into two groups according to the occurrence or absence of flare-ups, as defined by the systemic lupus erythematosus disease activity index (SLEDAI. The presence or absence of flare-ups and renal involvement was considered to be the independent variable and the other results were dependent variables. RESULTS: Flare-ups occurred in 85.3% of cases, and were most significant when there was renal involvement. This was related to greater numbers of women with preeclampsia and poor perinatal outcome. Intrauterine growth restriction was more common in the women with active disease. Placental weight was significantly lower in the women with renal involvement. CONCLUSIONS: Flare-ups and renal involvement in lupus patients during pregnancy are associated with increased maternal and perinatal complications.

  16. Managing hyperthyroidism in pregnancy: current perspectives

    Science.gov (United States)

    Andersen, Stine Linding; Laurberg, Peter

    2016-01-01

    Hyperthyroidism in women who are of childbearing age is predominantly of autoimmune origin and caused by Graves’ disease. The physiological changes in the maternal immune system during a pregnancy may influence the development of this and other autoimmune diseases. Furthermore, pregnancy-associated physiological changes influence the synthesis and metabolism of thyroid hormones and challenge the interpretation of thyroid function tests in pregnancy. Thyroid hormones are crucial regulators of early development and play an important role in the maintenance of a normal pregnancy and in the development of the fetus, particularly the fetal brain. Untreated or inadequately treated hyperthyroidism is associated with pregnancy complications and may even program the fetus to long-term development of disease. Thus, hyperthyroidism in pregnant women should be carefully managed and controlled, and proper management involves different medical specialties. The treatment of choice in pregnancy is antithyroid drugs (ATDs). These drugs are effective in the control of maternal hyperthyroidism, but they all cross the placenta, and so need careful management and control during the second half of pregnancy considering the risk of fetal hyper- or hypothyroidism. An important aspect in the early pregnancy is that the predominant side effect to the use of ATDs in weeks 6–10 of pregnancy is birth defects that may develop after exposure to available types of ATDs and may be severe. This review focuses on four current perspectives in the management of overt hyperthyroidism in pregnancy, including the etiology and incidence of the disease, how the diagnosis is made, the consequences of untreated or inadequately treated disease, and finally how to treat overt hyperthyroidism in pregnancy.

    Hypoxia during pregnancy can adversely affect development. This study, addressed the impact of prenatal hypoxia on thymus development in the rodent offspring. Pregnant Balb/c mice were exposed to hypoxia or normoxia during pregnancy, and the thymuses of their offspring were tested. Chronic hypoxia during pregnancy resulted in significantly decreased fetal body weight, with an increased thymus-to-body weight ratio. Histological analysis revealed a smaller cortical zone in the thymus of the offspring exposed to hypoxia. A reduction in the cortical T lymphocyte population corresponded to increased mRNA abundance of caspase 3 (Casp3) and decreased expression of the proliferation marker Ki-67 (Mki67). Differences in T lymphocyte sub-populations in the thymus further indicate that thymus development in offspring was retarded or stagnated by prenatal hypoxia. The abundance of IL2 and its receptor was reduced in the thymus following prenatal hypoxia. This was accompanied by an increase in thymus HIF1A and IKKβ and a decrease in phosphorylated NFKB, MAP2K1, and MAPK1/3 compared to control pregnancies. Together, these results implicate deficiencies in IL2-mediated signaling as one source of prenatal-hypoxia-impaired thymus development.

    Many nondomestic felids are highly endangered, and captive breeding programs have become essential components of holistic conservation efforts for these species. The ability to diagnose pregnancy early in gestation is fundamental to developing effective breeding programs. The purpose of this study was to develop a radioimmunoassay (RIA) for the detection of urinary relaxin in felids and assess its applicability for early, noninvasive pregnancy diagnosis in domestic cats (Felis silvestris catus) and leopards (Panthera pardus). Urine was collected from pregnant and nonpregnant domestic cats and leopards at mating, and then weekly thereafter for the duration of gestation. Paired serum samples were also collected from the domestic cats. A RIA for relaxin that uses an antiserum against synthetic canine relaxin was validated for felid urine and shown to detect relaxin immunoreactivity in pregnant cat urine subjected to acid-acetone extraction. In the cat, urinary relaxin was first detected between Days 21 and 28 of gestation; levels peaked at 42-49 days, and the concentrations then declined over 2 wk prior to parturition. The urinary relaxin profiles of the cat mirrored those in serum. In the leopard, urinary relaxin was first detected at Day 25-28 of gestation; levels peaked at Day 60-64 and declined in the last 3-4 wk of pregnancy. These results indicate that measurement of urinary relaxin in the cat and leopard provides a reliable method for pregnancy determination from as early as 3-4 wk of gestation. This method of pregnancy diagnosis and monitoring may prove useful in the breeding management of domestic cats and other felid and canid species, and provides a foundation for future studies on pregnancy in captive exotic carnivores.

    To assess the validity of self-reported maternal and infant health indicators reported by mothers an average of 4 months after delivery. Three validity measures-sensitivity, specificity and positive predictive value (PPV)-were calculated for pregnancy history, pregnancy complications, health care utilization, and infant health indicators self-reported on the Pregnancy Risk Assessment Monitoring System (PRAMS) questionnaire by a representative sample of mothers delivering live births in New York City (NYC) (n = 603) and Vermont (n = 664) in 2009. Data abstracted from hospital records served as gold standards. All data were weighted to be representative of women delivering live births in NYC or Vermont during the study period. Most PRAMS indicators had >90 % specificity. Indicators with >90 % sensitivity and PPV for both sites included prior live birth, any diabetes, and Medicaid insurance at delivery, and for Vermont only, infant admission to the NICU and breastfeeding in the hospital. Indicators with poor sensitivity and PPV (urinary tract infection or kidney infection, and for NYC only, preterm labor, prior low-birth-weight birth, and prior preterm birth. For Vermont only, receipt of an HIV test during pregnancy had poor sensitivity and PPV. Mothers accurately reported information on prior live births and Medicaid insurance at delivery; however, mothers' recall of certain pregnancy complications and pregnancy history was poor. These findings could be used to prioritize data collection of indicators with high validity.

    Gestational genitourinary infections, which have been associated with neurodevelopmental impairments among infants born near term, have not been studied among very preterm infants. The mothers of 989 infants born before 28 weeks of gestation were interviewed about urine, bladder, or kidney infections (UTIs) and cervical or vaginal infections (CVIs) during pregnancy, as well as other exposures and characteristics, and their charts were reviewed for the Extremely Low Gestational Age Newborns (ELGAN) Study (2002-2004). At 2 years of age, these infants underwent a neurodevelopmental assessment. Generalized estimating equation logistic regression models of developmental adversities were used to adjust for potential confounders. Infants born to women who reported a UTI were less likely than were others to have a very low Mental Development Index (adjusted odds ratio = 0.5; 95% confidence interval: 0.3, 0.8), whereas infants born to women who reported a CVI were more likely than others to have a low Psychomotor Development Index (adjusted odds ratio = 1.7; 95% confidence interval: 1.04, 2.7). In this high-risk sample, maternal gestational CVI, but not UTI, was associated with a higher risk of impaired motor development at 2 years of age. The apparent protective effect of UTI might be spurious, reflect confounding due to untreated asymptomatic bacteriuria among women who were not given a diagnosis of UTI, or reflect preconditioning.

    Placental development is markedly abnormal in women bearing a fetus with trisomy 21, with defective syncytiotrophoblast (ST) formation and function. The ST occurs from cytotrophoblast (CT) fusion and plays an essential role by secreting human chorionic gonadotropin (hCG), which is essential to placental development. In trisomy of chromosome 21 (T21) pregnancies, CTs do not fuse and differentiate properly into STs, leading to the secretion of an abnormal and weakly bioactive hCG. In this study we report for the first time, a marked decrease in the number of mature hCG receptor (LH/CG-R) molecules expressed at the surface of T21-affected CTs. The LH/CG-R seems to be functional based on sequencing that revealed no mutations or deletions and binding of recombinant hCG as well as endogenous hCG. We hypothesize that weakly bioactive hCG and lower LH/CG-R expression may be involved in the defect of ST formation. Interestingly, the defective ST formation is mimicked in normal CT cultures by using LH/CG-R small interfering RNA, which result in a lower hCG secretion. Furthermore, treatment of T21-affected CTs with recombinant hCG overcomes in vitro the T21 phenotype, allowing CTs to fuse and form a large ST. These results illustrate for the first time in trisomy 21 pathology, how abnormal endogenous hCG signaling impairs human placental development.

    This report discusses test campaign GCT3 of the Halliburton KBR transport reactor train with a Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The transport reactor is an advanced circulating fluidized-bed reactor designed to operate as either a combustor or a gasifier using one of two possible particulate control devices (PCDs). The transport reactor was operated as a pressurized gasifier during GCT3. GCT3 was planned as a 250-hour test run to commission the loop seal and continue the characterization of the limits of operational parameter variations using a blend of several Powder River Basin coals and Bucyrus limestone from Ohio. The primary test objectives were: (1) Loop Seal Commissioning--Evaluate the operational stability of the loop seal with sand and limestone as a bed material at different solids circulation rates and establish a maximum solids circulation rate through the loop seal with the inert bed. (2) Loop Seal Operations--Evaluate the loop seal operational stability during coal feed operations and establish maximum solids circulation rate. Secondary objectives included the continuation of reactor characterization, including: (1) Operational Stability--Characterize the reactor loop and PCD operations with short-term tests by varying coal feed, air/coal ratio, riser velocity, solids circulation rate, system pressure, and air distribution. (2) Reactor Operations--Study the devolatilization and tar cracking effects from transient conditions during transition from start-up burner to coal. Evaluate the effect of process operations on heat release, heat transfer, and accelerated fuel particle heat-up rates. Study the effect of changes in reactor conditions on transient temperature profiles, pressure balance, and product gas composition. (3) Effects of Reactor Conditions on Syngas Composition--Evaluate the effect of air distribution, steam

    Full Text Available   Objective(s: Previous studies have shown that thyroid hormones are necessary for normal development of many organs and because of the importance of skin as the largest and the most important organ in human body protection in spite of external environment, the study of thyroid hormones effects on skin development is considerable. In this survey we have tried to study the effects of maternal hypothyroidism on skin development in fetus during pregnancy and lactation by immunohistochemistry technique.   Materials and Methods: Rats were divided into 4 groups, hypothyroids, hyperthyroids, hypothyroids are treated with levothyroxin and a control group. The rat mothers were exposed to PTU with 50 mg/lit dosage and levothyroxin with 1 mg/lit dosage and PTU and levothyroxin simultaneously and with the same dosage respectively in hypothyroid, hyperthyroid and treated hypothyroids with levothyroxin groups. After 14 days, blood sample was taken from mothers, and if thyroid hormones level had change well, mating was allowed. After pregnancy and delivery, 1th day dorsal skin (as the sample for pregnancy assay and 10th day skin (as for lactation assay was used for immunohystochemical and morphometric studies. Results: In this study it was observed that maternal hypothyroidism during pregnancy and lactation causes significant increase in laminin expression, in most areas of skin, and maternal hyperthyroidism during pregnancy and lactation causes significant decrease in laminin expression. Also significant decrease was observed in hair follicles number and epidermis thickness in hypothyroidism groups. Conclusion: This study showed maternal hypothyroidism causes significant decrease in epidermis thickness and hair follicles number and it causes less hair in fetus. Also maternal hypothyroidism causes large changes in laminin expression in different parts of skin. At the same time,maternal hyperthyroidism causes opposite results. In fact, thyroid hormones

    Maternal obesity during pregnancy is an important public health problem in Western countries. Currently, obesity prevalence rates in pregnant women are estimated to be as high as 30%. In addition, approximately 40% of women gain an excessive amount of weight during pregnancy in Western countries. An accumulating body of evidence suggests a long-term impact of maternal obesity and excessive weight gain during pregnancy on adiposity, cardiovascular and metabolic related health outcomes in the offspring in fetal life, childhood and adulthood. In this review, we discuss results from recent studies, potential underlying mechanisms and challenges for future epidemiological studies.

    The use of SQUID magnetometers for non-invasive in utero assessment of cardiac electrical disturbances has already been shown to be a valuable clinical tool. In this way, its applicability also for the complicated case of twin pregnancy, in which the proximity of the cardiac magnetic source of each fetus can hamper the individual analysis of cardiac electrical activity, is of clinical interest. In this paper, we present fetal magnetocardiography performed on a mother pregnant of twins with 26 weeks gestational age, measured inside a magnetically shielded room, by using two identical 31-channel low- Tc SQUID magnetometer systems. Each sensor array has been positioned over one of the fetuses, according to its heart position previously assessed with the aid of ultrasound measurements. The raw data is initially averaged in time and, afterwards, analyzed by means of time plots and isofield maps. The time recordings allow the study of the morphology of each fetus’ cardiac signal and the cardiac time intervals. The resultant equivalent dipole obtained from the isofield maps indicates the position and orientation of each fetus heart. The results agree with the ultrasound analysis performed immediately before the measurements and used to obtain the approximate location of the fetuses’ hearts. Since a distinct analysis of the cardiac electrical activity of each fetus could be achieved, the results indicate the potential of the fetal magnetocardiography in the individual antenatal diagnosis of each one of the fetuses of a twin pregnancy.

    Despite clear differences in immune system responses and in the prevalence of autoimmune diseases between males and females, there is little understanding of the processes involved. In this study, we identified a gene signature of immature-like neutrophils, characterized by the overexpression of genes encoding for several granule-containing proteins, which was found at higher levels (up to 3-fold) in young (20–30 y old) but not older (60 to >89 y old) males compared with females. Functional and phenotypic characterization of peripheral blood neutrophils revealed more mature and responsive neutrophils in young females, which also exhibited an elevated capacity in neutrophil extracellular trap formation at baseline and upon microbial or sterile autoimmune stimuli. The expression levels of the immature-like neutrophil signature increased linearly with pregnancy, an immune state of increased susceptibility to certain infections. Using mass cytometry, we also find increased frequencies of immature forms of neutrophils in the blood of women during late pregnancy. Thus, our findings show novel sex differences in innate immunity and identify a common neutrophil signature in males and in pregnant women. PMID:28179497

    The placenta forms the interface between the maternal and fetal circulation and is critical for the establishment of a healthy pregnancy. Specialized trophoblast cells derived from the embryonic trophectoderm play a pivotal role in the establishment of the placenta. Leukemia inhibitory factor (LIF) is one of the predominant cytokines present in the placenta during early pregnancy. LIF has been shown to regulate trophoblast adhesion and invasion in vitro, however its precise role in vivo is unknown. We hypothesized that LIF would be required for normal placental development in mice. LIF and LIFRα were immunolocalized to placental trophoblasts and fetal vessels in mouse implantation sites during mid-gestation. Temporally blocking LIF action during specific periods of placental development via intraperitoneal administration of our specific LIFRα antagonist, PEGLA, resulted in abnormal placental trophoblast and vascular morphology and reduced activated STAT3 but not ERK. Numerous genes regulating angiogenesis and oxidative stress were altered in the placenta in response to LIF inhibition. Pregnancy viability was also significantly compromised in PEGLA treated mice. Our data suggest that LIF plays an important role in placentation in vivo and the maintenance of healthy pregnancy.

    Maternal obesity increases the risk of obesity in the offspring, and obesity is accompanied by an increase in blood leptin levels. Leptin can influence the progeny metabolism via its influence on fetal growth and, possibly, via its action on AgRP expression in placenta. The "yellow" mutation at the mouse agouti locus (A(y)) evokes obesity and increases blood leptin levels in pregnant mice. The aim was to examine the influence of A(y) mutation in pregnant mice on fetal weight, placental expression of AgRP gene and food intake and obesity development in progeny. A(y) pregnant females as compared to control ones had increased circulating leptin levels on days 13 and 18 of pregnancy. Both fetal weight and placental expression of AgRP gene were increased on day 13 of pregnancy and decreased on day 18 of pregnancy in A(y) females as compared to control ones. Both control (a/a) and obesity prone (A(y)/a) male young born to A(y) mothers had lowered body weight and enhanced food intake between 5 and 11 weeks of age as compared to male progeny of control mothers. The enhanced leptin levels during pregnancy in mice are associated with retardation of obesity development in obesity prone male offspring and with changes in fetal weight and AgRP gene expression in placenta.

    Numerous antral follicles develop during the second half of pregnancy in the golden hamster even though LH and FSH are maintained at basal levels. To investigate the possible hormone actions of activin A associated with follicular development, pregnant golden hamsters were placentectomized on day 6 of pregnancy and animals were sacrificed at day 8, 10, 12, or 14 of pregnancy. There was a drastic decrease in the plasma concentrations of activin A from day 10 of pregnancy in the operated group compared to the controls. Positive immunohistochemical staining of inhibin/activin subunits betaA and betaB in the syncytiotrophoblast of the placenta revealed the source of activin A, AB, or B. The number of healthy follicles did not change until day 12 between the operated and the control groups, but decreased in numbers in the operated groups thereafter. The decreased concentrations of inhibin A, B, and estradiol-17beta in the operated groups at day 10 and 12 correlated well with the number of mature follicles in response to hCG treatment. In conclusion, we revealed that activin A secreted from the placenta induces folliculogenesis to maintain the high levels of estradiol-17beta needed to induce uterine dilatation for fetus growth and impending parturition.

    The Exploration Medical Capability (ExMC) Element systems engineering goals include defining the technical system needed to implement exploration medical capabilities for Mars. This past year, scenarios captured in the medical system concept of operations laid the foundation for systems engineering technical development work. The systems engineering team analyzed scenario content to identify interactions between the medical system, crewmembers, the exploration vehicle, and the ground system. This enabled the definition of functions the medical system must provide and interfaces to crewmembers and other systems. These analyses additionally lead to the development of a conceptual medical system architecture. The work supports the ExMC community-wide understanding of the functional exploration needs to be met by the medical system, the subsequent development of medical system requirements, and the system verification and validation approach utilizing terrestrial analogs and precursor exploration missions.

    Formaldehyde (FA) is an environmental and occupational pollutant, and its toxic effects on the immune system have been shown. Nevertheless, no data are available regarding the programming mechanisms after FA exposure and its repercussions for the immune systems of offspring. In this study, our objective was to investigate the effects of low-dose exposure of FA on pregnant rats and its repercussion for the development of allergic lung inflammation in offspring. Pregnant Wistar rats were assigned in 3 groups: P (rats exposed to FA (0.75 ppm, 1 h/day, 5 days/week, for 21 days)), C (rats exposed to vehicle of FA (distillated water)) and B (rats non-manipulated). After 30 days of age, the offspring was sensitised with ovalbumin (OVA)-alum and challenged with aerosolized OVA (1%, 15 min, 3 days). After 24 h the OVA challenge the parameters were evaluated. Our data showed that low-dose exposure to FA during pregnancy induced low birth weight and suppressed the development of allergic lung inflammation and tracheal hyperresponsiveness in offspring by mechanisms mediated by reduced anaphylactic antibodies synthesis, IL-6 and TNF-alpha secretion. Elevated levels of IL-10 were found. Any systemic alteration was detected in the exposed pregnant rats, although oxidative stress in the uterine environment was evident at the moment of the delivery based on elevated COX-1 expression and reduced cNOS and SOD-2 in the uterus. Therefore, we show the putative programming mechanisms induced by FA on the immune system for the first time and the mechanisms involved may be related to oxidative stress in the foetal microenvironment. - Highlights: • Formaldehyde exposure does not cause lung inflammation in pregnant rats. • Formaldehyde exposure suppresses allergic lung inflammation in the offspring. • Formaldehyde exposure induces oxidative stress in uterine environment.

    Interstitial pregnancy is defined as any gestation that develops in the uterine portion of the fallopian tubes lateral to the round ligament. Interstitial pregnancies account for 2-4% of all ectopic pregnancies and have been reported to have an associated 2% to 2.5% maternal mortality rate. The traditional treatment for interstitial pregnancy using surgical cornual resection may cause infertility or uterine rupture in subsequent pregnancies. Recently, the early identification of intact interstitial pregnancy has been made possible in many cases with high resolution transvaginal ultrasound as well as more sensitive assays for betahuman chorionic gonadotropin ({beta}-hCG). The treatment includes: hysteroscopic transcervical currettage, local and systemic methotrexate (MTX) therapy and prostaglandin or potassium chloride injection of the ectopic mass under sonographic guidance. We describe a case of successful treatment of interstitial pregnancy using uterine artery embolization, after failure of methotrexate treatment.

    To investigate subacute exposure of airborne particulate matter (PM) on pregnancy and fetal development in female mice. Forty female and forty male ICR adult mice were caged separately by 1:1 to get access to pregnancy. The pregnant mice were randomized into control group (A), small (B), middle (C), large (D) or overdose (E) PM challenge groups (n = 8-11), and were administered with 30 µl of phosphate buffered solution (A) or resuspended standard PM SRM 1649a at 0.09 (B), 0.52 (C), 1.85 (D) or 69.2 (E) µg/µl, once per trid from d 0 till d 19 of pregnancy via instillation onto the base of the tongue. Fetal mice were harvested by cesarean section at the time when spontaneous delivery occurred. Body weight of the pregnant mice, gestational days, intrauterine survival and growth, hepatic and pneumonic histopathological changes of the fetal mice were investigated. Lung/body and liver/body weight ratios were calculated. Expressions of mRNA and protein of CYP1A1 in the fetal lung and CYP1A2 in the fetal liver were assayed. (1) All of the pregnant mice survived pregnancy throughout the entire experiment. Body weight of the pregnant mice was not significantly different among all the groups at gestational d 1 and 7 (P > 0.05), but significantly lower in group E [(41.8 ± 5.8) and (48.9 ± 8.9) g] than in group A [(45.9 ± 1.8) and (56.2 ± 4.9) g] at gestational d 14 and 18 (P 0.05). Lung/body and liver/body weight ratios of the fetal mice were significantly increased in group E [(1.21 ± 0.18) and (4.68 ± 0.21)%] as compared with groups A, B, C and D (P 0.05) despite of an increasing tendency. (3) Pathological changes in the liver and lung of the fetuses were conspicuous in group E. The fetal liver injury was histopathologically evidenced by deranged tissue structure, degenerated parenchyma of hepatic cells, and mildly stained cytoplasm.

    Lupus anticoagulant (LAC), a serum antiphospholipid autoantibody, is believed to be one of the causes of infertility or fetal loss. The purpose of the present study was to evaluate the role of LAC in the pathogenesis of hypertension during pregnancy. In this study, 20 pregnant women with hypertension were classified into two groups: 14 patients who did not have hypertension before the pregnancy but developed it during the pregnancy (pregnancy-induced hypertension; Group A) and 6 patients who had hypertensive or renal disease before the pregnancy, and developed further hypertension during the pregnancy (pregnancy-aggravated hypertension; Group B). A LAC coagulation assay was performed, and the presence of LAC in each group was compared. All 14 patients in group A were LAC-negative. In contrast, 3 of the 6 patients in group B were LAC-positive, and had clinical autoimmune diseases. The incidence of pregnancy-induced hypertension was also examined in 15 pregnancies from 9 LAC-positive women who had a history of repeated fetal loss but no systemic autoimmune disease (Group C). None of these 15 pregnancies had hypertensive complications, even when they reached term. In the placentas of LAC-positive women, no characteristic changes other than fibrinoid degeneration and microscopic infarction were observed upon histological examination. These results suggest that LAC does not relate with the onset of hypertension during pregnancy.

    Promoting preconception health can potentially improve women's health and pregnancy outcomes. Evidence-based interventions exist to reduce many maternal behaviors and chronic conditions that are associated with adverse pregnancy outcomes such as tobacco use, alcohol use, inadequate folic acid intake, obesity, hypertension, and diabetes. The 2006 national recommendations to improve preconception health included monitoring improvements in preconception health by maximizing public health surveillance (CDC. Recommendations to improve preconception health and health care-United States: a report of the CDC/ATSDR Preconception Care Work Group and the Select Panel on Preconception Care. MMWR 2006;55[No. RR-6]). 2009 for 38 indicators; 2008 for one indicator. DESCRIPTION OF SURVEILLANCE SYSTEMS: The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing state- and population-based surveillance system designed to monitor selected self-reported maternal behaviors, conditions, and experiences that occur shortly before, during, and after pregnancy among women who deliver live-born infants. The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing state-based telephone survey of noninstitutionalized adults aged ≥18 years in the United States that collects state-level data on health-related risk behaviors, chronic conditions, and preventive health services. This surveillance summary includes PRAMS data from 29 reporting areas (n = 40,388 respondents) and BRFSS data from 51 reporting areas (n = 62,875 respondents) for nonpregnant women of reproductive age (aged 18-44 years). To establish a comprehensive, nationally recognized set of indicators to be used for monitoring, evaluation, and response, a volunteer group of policy and program leaders and epidemiologists identified 45 core state preconception health indicators, of which 41 rely on PRAMS or BRFSS as data sources. This report includes 39 of the 41 core state preconception health indicators for which

    Full Text Available BACKGROUND Pregnancy is a physiological status of a woman. Every organ is adapting in order to accept another human body. The main changes occur in the endocrine, immune, metabolic and vascular systems. The skin is no exception. Many skin changes during pregnancy are considered to be normal or physiological including striae gravidarum or melasma. These physiological skin changes are usually well tolerated by the pregnant woman. There is no balance between these systems, however, and abnormalities can appear. Immunologic status of the woman plays an important role in the manifestations exhibited in the skin. Alterations of the skin during pregnancy can be classified as physiologic skin changes, changes in pre-existing skin diseases and specific dermatoses of pregnancy. MATERIALS AND METHODS 200 pregnant women with skin manifestations attending Dermatology and Obstetric departments attached to Government General Hospital, Kurnool, were studied. 1. A detailed proforma was taken, which included: a. Detailed history including chief complaints related to skin. b. Onset in relation to duration of pregnancy. c. Complete general physical and systemic examination. d. Associated skin/medical disorders. 2. Investigations-CBP, CUE, RBS, LFT, HBsAg, VDRL, HIV 1 and 2 were done routinely. 3. KOH mount, saline mount and skin biopsy performed wherever required. Inclusion criteria- All pregnant women having skin lesions were included in the study irrespective of the duration of pregnancy and gravidity. Exclusion criteria- Pregnant women having any underlying medical diseases. All pregnant women attending antenatal OPD and those admitted into wards having symptoms related to skin and mucosa, at KIMS Hospital are studied. 1.

    Getting To Outcomes (GTO), an innovative framework for planning, implementing, evaluating, and sustaining interventions has been shown to be effective in helping community-based organizations (CBOs) introduce science-based approaches into their prevention work. However, the Interactive Systems Framework (ISF) suggests that adopting innovations like GTO requires a significant amount of capacity building through training and technical assistance (T/TA). In this study, 11 CBOs and three schools in South Carolina entered into a 3 year program of intense and proactive T/TA based on the ISF to learn how to apply an adaptation of GTO (Promoting Science-Based Approaches-Getting To Outcomes, PSBA-GTO) to their teen pregnancy prevention programs. Using semi-structured interviews, the partnering organizations were assessed at three points in time, pre-T/TA, 12 months, and post T/TA (30 months) for their performance of the steps of GTO in their work. The seven organizations which participated in T/TA until the end of the project received an average of 76 h of TA and 112 h of training per organization. Interview results showed increased performance of all 10 steps of PSBA-GTO by these organizations when conducting their teen pregnancy programs. These results suggest targeted and proactive T/TA can successfully bridge the gap between research and practice by using a three part delivery system, as prescribed in the ISF, which relies on an intermediary prevention support system to ensure accurate and effective translation of research to the everyday work of community-based practitioners.

    State-of-the-art (SOA) carbon dioxide (CO2) reduction technology for the International Space Station produces methane as a byproduct. This methane is subsequently vented overboard. The associated loss of hydrogen ultimately reduces the mass of oxygen that can be recovered from CO2 in a closed-loop life support system. As an alternative to SOA CO2 reduction technology, NASA is exploring a Series-Bosch system capable of reducing CO2 with hydrogen to form water and solid carbon. This results in 100% theoretical recovery of oxygen from metabolic CO2. In the past, Bosch-based technology did not trade favorably against SOA technology due to a high power demand, low reaction efficiencies, concerns with carbon containment, and large resupply requirements necessary to replace expended catalyst cartridges. An alternative approach to Bosch technology, labeled "Series-Bosch," employs a new system design with optimized multi-stage reactors and a membrane-based separation and recycle capability. Multi-physics modeling of the first stage reactor, along with chemical process modeling of the integrated system, has resulted in a design with potential to trade significantly better than previous Bosch technology. The modeling process and resulting system architecture selection are discussed.

The bacteriuria in pregnancy still be one of the principal factor of morbidity and mortality, maternal and perinatal. Thus, proposing to analyze the bibliographic production around bacteriuria in pregnancy has developed this study. Proceded to the investigation of 06 national articles, published from 2003 to 2013, on the LILACS database. Were used as descriptors: Bacteriuria and Pregnancy. Defined as bacteriuria from quantitative colony forming units per mililiter of urine (CFU / ml equal to or higher than 105. With etiology is observed Escherichia coli as a major etiologic agent and urine culture the most efficient diagnostic method. The results also attach the treatment of bacteriuria during pregnancy independently of the occurrence of symptoms and tracking of the bacteriuria from the first trimester of pregnancy to prevent maternal and fetal complications.

  10. Adaptive evolution at immune system genes and deep pregnancy implantation in primates.

    2015-01-01

    A major evolutionary change in the lineage ancestral to humans, chimpanzee and gorilla (HCG) has been the embedding of the embryo into maternal tissue. Thus, the first layer of cells (trophoblast) to differentiate after fertilization must adapt to invade the uterus. Such event would likely leave signatures of positive selection at genes with roles in embryo implantation. Here, 163 pregnancy implantation genes are tested for evidence of adaptive diversification in the ancestral lineage to HCG. Two immune system genes, HLA-E and KIR2DL4 showed evidence of positive selection. Some of the positive selected sites involve amino acid substitution with predicted damaging effects on protein function, thus highlighting the possibility of antagonistic pleiotropic effects. Selection at a gene coding for a receptor expressed in uterine cells (KIR) that interacts with trophoblast human leukocyte antigen (HLA) genes suggests a main role for immunological adaptations in embryo deep invasion of the maternal endometrium.

    The fetal central nervous system can already be examined in the first trimester of pregnancy. Acrania, alobar holoprosencephaly, cephaloceles, and spina bifida can confidently be diagnosed at that stage and should actively be looked for in every fetus undergoing first-trimester ultrasound. For some other conditions, such as vermian anomalies and agenesis of the corpus callosum, markers have been identified, but the diagnosis can only be confirmed in the second trimester of gestation. For these conditions, data on sensitivity and more importantly specificity and false positives are lacking, and one should therefore be aware not to falsely reassure or scare expecting parents based on first-trimester findings. This review summarizes the current knowledge of first-trimester neurosonography in the normal and abnormal fetus and gives an overview of which diseases can be diagnosed.

    To determine the efficacy and safety of primary medical treatment with systemic methotrexate (MTX) in caesarean scar ectopic pregnancy, we conducted a Medline/PubMed search on the relevant English literature from January 1978 to January 2012. The search yielded 27 publications of 40 cases of caesarean scar ectopic pregnancy. The literature search showed a very liberal use of systemic MTX treatment with unfavourable outcomes, although the major determinant of the clinical efficacy was found in here to be β-hCG level together with embryonic cardiac activity (ECA) status. A caesarean scar ectopic pregnancy presented with a serum β-hCG concentration of ≤ 12,000 mIU/ml (odds ratio, OR 5.68, 95% confidence interval, CI, 1.37-23.48) and absence of ECA (OR 4.80, 95% CI, 1.14-20.08) was found to be associated with higher efficacy rate of primary systemic MTX treatment. Administration of primary systemic MTX treatment was found to be ideal for a caesarean scar ectopic pregnancy presented before 8 weeks' gestation, with a β-hCG concentration of ≤ 12,000 mIU/ml together with an absent ECA (OR 14.52, 95% CI, 2.36-89.09).

    Preterm birth is the single leading cause of perinatal mortality in developed countries, affecting approximately 12% of pregnancies and accounting for 75% of neonatal loss in the United States. Despite the prevalence and severity of premature delivery, the causes and mechanisms that underlie spontaneous and idiopathic preterm birth remain unknown. Our inability to elucidate these fundamental causes has been attributed to a poor understanding of the signaling pathways associated with the premature induction of parturition and a lack of suitable animal models available for preterm birth research. In this study, we describe the generation and analysis of a novel conditional knockout of the transforming growth factor beta (TGFB) superfamily member, Nodal, from the maternal reproductive tract of mice. Strikingly, uterine Nodal knockout females exhibited a severe malformation of the maternal decidua basalis during placentation, leading to significant intrauterine growth restriction, and ultimately preterm birth and fetal loss on Day 17.5 of gestation. Using several approaches, we characterized aberrant placental development and demonstrated that reduced proliferation combined with increased apoptosis resulted in a diminished decidua basalis and compromised maternal-fetal interface. Last, we evaluated various components of the established parturition cascade and determined that preterm birth derived from the maternal Nodal knockout occurs prior to PTGS2 (COX-2) upregulation at the placental interface. Taken together, the results presented in this study highlight an in vivo role for maternal NODAL during placentation, present an interesting link between disrupted decidua basalis formation and premature parturition, and describe a potentially valuable model toward elucidating the complex processes that underlie preterm birth.

    Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that affects women of childbearing years. Pregnancy with SLE is associated with an increase risk of adverse maternal and fetal outcomes. Recently, tacrolimus has been used for steroid-resistant SLE. However, because of limited information regarding the use of immunosuppressants during pregnancy, many SLE patients give up pregnancy. We report two SLE patients receiving tacrolimus who hoped to become pregnant. Patient 1 was a 31-year-old woman diagnosed with SLE 6 years earlier and treated with tacrolimus for 3 years because her symptoms were not controlled with other immunosuppressants. Patient 2 was a 28-year-old woman diagnosed with SLE 13 years earlier and treated with tacrolimus for 3 years because her symptoms were not controlled with prednisolone alone. The medical ethics board in our hospital approved the use of tacrolimus during pregnancy and lactation, and informed consent was obtained from the patients. Both patients were well controlled during pregnancy with prednisolone (Patient 1: 12 mg/day and Patient 2: 10 mg/day) and tacrolimus therapy (3 mg/day). They had healthy newborns and continued breastfeeding with tacrolimus therapy. The blood concentrations of tacrolimus 12 hours after taking tacrolimus was 3.0 ng/ml in Patient 1 and 2.9 ng/ml in Patient 2, and their newborns' blood concentrations of tacrolimus 1 hour after breastfeeding were 0.2 ng/ml and 0.5 ng/ml, respectively. Both newborns are healthy for at least 3 years after birth. This is the first report on the safety of tacrolimus for pregnancy and lactation in patients with SLE.

    Full Text Available Abstract Background Hypertension in pregnancy stand alone or with proteinuria is one of the leading causes of maternal mortality and morbidity in the world. Epidemiological and clinical studies have shown that an inverse relationship exists between calcium intake and development of hypertension in pregnancy though the effect varies based on baseline calcium intake and pre-existing risk factors. The purpose of this review was to evaluate preventive effect of calcium supplementation during pregnancy on gestational hypertensive disorders and related maternal and neonatal mortality in developing countries. Methods A literature search was carried out on PubMed, Cochrane Library and WHO regional databases. Data were extracted into a standardized excel sheet. Identified studies were graded based on strengths and limitations of studies. All the included studies were from developing countries. Meta-analyses were generated where data were available from more than one study for an outcome. Primary outcomes were maternal mortality, eclampsia, pre-eclampsia, and severe preeclampsia. Neonatal outcomes like neonatal mortality, preterm birth, small for gestational age and low birth weight were also evaluated. We followed standardized guidelines of Child Health Epidemiology Reference Group (CHERG to generate estimates of effectiveness of calcium supplementation during pregnancy in reducing maternal and neonatal mortality in developing countries, for inclusion in the Lives Saved Tool (LiST. Results Data from 10 randomized controlled trials were included in this review. Pooled analysis showed that calcium supplementation during pregnancy was associated with a significant reduction of 45% in risk of gestational hypertension [Relative risk (RR 0.55; 95 % confidence interval (CI 0.36-0.85] and 59% in the risk of pre-eclampsia [RR 0.41; 95 % CI 0.24-0.69] in developing countries. Calcium supplementation during pregnancy was also associated with a significant reduction

    Amanda M Dettmer

    Full Text Available Studies examining hormones throughout pregnancy and lactation in women have been limited to single, or a few repeated, short-term measures of endocrine activity. Furthermore, potential differences in chronic hormonal changes across pregnancy/lactation between first-time and experienced mothers are not well understood, especially as they relate to infant development. Hormone concentrations in hair provide long-term assessments of hormone production, and studying these measures in non-human primates allows for repeated sampling under controlled conditions that are difficult to achieve in humans. We studied hormonal profiles in the hair of 26 female rhesus monkeys (Macaca mulatta, n=12 primiparous, to determine the influences of parity on chronic levels of cortisol (hair cortisol concentration, HCC and progesterone (hair progesterone concentration, HPC during early- to mid-pregnancy (PREG1, in late pregnancy/early lactation (PREG2/LACT1, and in peak lactation (LACT2. We also assessed infants' neurobehavioral development across the first month of life. After controlling for age and stage of pregnancy at the first hair sampling period, we found that HCCs overall peaked in PREG2/LACT1 (p=0.02, but only in primiparous monkeys (p<0.001. HPCs declined across pregnancy and lactation for all monkeys (p<0.01, and primiparous monkeys had higher HPCs overall than multiparous monkeys (p=0.02. Infants of primiparous mothers had lower sensorimotor reflex scores (p=0.02 and tended to be more irritable (p=0.05 and less consolable (p=0.08 in the first month of life. Moreover, across all subjects, HCCs in PREG2/LACT1 were positively correlated with irritability (r(s=0.43, p=0.03 and negatively correlated with sensorimotor scores (r(s=-0.41, p=0.04. Together, the present results indicate that primiparity influences both chronic maternal hormonal profiles and infant development. These effects may, in part, reflect differential reproductive and maternal effort in

    severe health worker shortages and resource limitations negatively affect quality of antenatal care (ANC) throughout sub-Saharan Africa. Group ANC, specifically CenteringPregnancy (CP), may offer an innovative approach to enable midwives to offer higher quality ANC. our overarching goal was to prepare to conduct a clinical trial of CenteringPregnancy-Africa (CP-Africa) in Malawi and Tanzania. In Phase 1, our goal was to determine the acceptability of CP as a model for ANC in both countries. In Phase 2, our objective was to develop CP-Africa session content consistent with the Essential Elements of CP model and with national standards in both Malawi and Tanzania. In Phase 3, our objective was to pilot CP-Africa in Malawi to determine whether sessions could be conducted with fidelity to the Centering process. Phases 1 and 2 took place in Malawi and Tanzania. Phase 3, the piloting of two sessions of CP-Africa, occurred at two sites in Malawi: a district hospital and a small clinic. we used an Action Research approach to promote partnerships among university researchers, the Centering Healthcare Institute, health care administrators, health professionals and women attending ANC to develop CP-Africa session content and pilot this model of group ANC. for Phases 1 and 2, members of the Ministries of Health, health professionals and pregnant women in Malawi and Tanzania were introduced to and interviewed about CP. In Phase 2, we finalised CP-Africa content and trained 13 health professionals in the Centering Healthcare model. In Phase 3, we conducted a small pilot with 24 pregnant women (12 at each site). participants enthusiastically embraced CP-Africa as an acceptable model of ANC health care delivery. The CP-Africa content met both CP and national standards. The pilot established that the CP model could be implemented with process fidelity to the 13 Essential Elements. Several implementation challenges and strategies to address these challenges were identified

    Studies conducted over the past 25 years have focussed on the role of periodontitis, an inflammatory condition of microbial aetiology 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 bacteraemias and systemic dissemination of inflammatory mediators produced in the periodontal tissues may result in systemic inflammation and endothelial dysfunction, and that bacteria of oral origin may translocate into the feto-placental unit. Epidemiological studies largely support an association between periodontitis and ASVD/APOs, independently 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 summarises key findings from mechanistic, association and intervention studies and attempts to reconcile the seemingly contradictory evidence that originates from different lines of investigation.

    Looked-after children (LAC) are at greater risk of teenage pregnancy than non-LAC, which is associated with adverse health and social consequences. Existing interventions have failed to reduce rates of teenage pregnancy in LAC. Peer mentoring is proposed as a means of addressing many of the factors associated with the increased risk of teenage pregnancy in this group. To develop a peer mentoring intervention to reduce teenage pregnancy in LAC. Phase I and II randomised controlled trial of a peer mentoring intervention for LAC; scoping exercise and literature search; national surveys of social care professionals and LAC; and focus groups and interviews with social care professionals, mentors and mentees. Three local authorities (LAs) in England. LAC aged 14-18 years (mentees/care as usual) and 19-25 years (mentors). Recruitment and training of mentors; randomisation and matching of mentors to mentees; and 1-year individual peer mentoring. pregnancy in LAC aged 14-18 years. sexual attitudes, behaviour and knowledge; psychological health; help-seeking behaviour; locus of control; and attachment style. A health economic evaluation was also carried out. In total, 54% of target recruitment was reached for the exploratory trial and 13 out of 20 mentors (65%) and 19 out of 30 LAC aged 14-18 years (63%) (recruited during Phases I and II) were retained in the research. The training programme was acceptable and could be manualised and replicated. Recruitment and retention difficulties were attributed to systemic problems and LA lack of research infrastructure and lack of additional funding to support and sustain such an intervention. Mentees appeared to value the intervention but had difficulty in meeting weekly as required. Only one in four of the relationships continued for the full year. A future Phase III trial would require the intervention to be modified to include provision of group and individual peer mentoring; internal management of the project, with support from an

    The in utero environment plays an essential role in shaping future growth and development. Psychological distress during pregnancy has been shown to perturb the delicate physiological milieu of pregnancy, and has been associated with negative repercussions in the offspring, including adverse birth outcomes, long-term defects in cognitive development, behavioral problems during childhood and high baseline levels of stress-related hormones. Fetal epigenetic programming, involving epigenetic processes, may help explain the link between maternal prenatal stress and its negative effects on the child. Given the potential long-term effects of early-life stress on a child's health, it is crucial to minimize maternal distress during pregnancy. A number of recent studies have examined the usefulness of mindfulness-based programs to reduce prenatal psychological stress and improve maternal psychological health, and these are reviewed here. Overall, the findings are promising, but more research is needed with large studies using randomized controlled study designs. It remains unclear whether or not such interventions could also improve child health outcomes, and whether these changes are modulated at the epigenetic level during fetal development. Further studies in this area are needed.

    A KRS is suggested through design requirement analysis of the buffer and the canister which are the constituent of disposal system engineered barrier and HLW management plans are proposed. In the aspect of radionuclide retention capacity, the thickness of the buffer is determined 0.5m, the shape to be disc and ring and the dry density to be 1.6 g/cm{sup 3}. The maximum temperature of the buffer is below 100 .deg. which meets the design requirement. And bentonite blocks with 5 wt% of graphite showed more than 1.0 W/mK of thermal conductivity without the addition of sand. The result of the thermal analysis for proposed double-layered buffer shows that decrease of 7 .deg. C in maximum temperature of the buffer. For the disposal canister, the copper for the outer shell material and cast iron for the inner structure material is recommended considering the results analyzed in terms of performance of the canisters and manufacturability and the geochemical properties of deep groundwater sampled from the research area with granite, salt water intrusion, and the heavy weight of the canister. The results of safety analysis for the canister shows that the criticality for the normal case including uncertainty is the value of 0.816 which meets subcritical condition. Considering nation's 'Basic Plan for Electric Power Demand and Supply' and based on the scenario of disposing CANDU spent fuels in the first phase, the disposal system that the repository will be excavated in eight phases with the construction of the Underground Research Laboratory (URL) beginning in 2020 and commissioning in 2040 until the closure of the repository is proposed. Since there is close correlation between domestic HLW management plans and front-end/back-end fuel cycle plans causing such a great sensitivity of international environment factor, items related to assuring the non-proliferation and observing the international standard are showed to be the influential factor and acceptability

    Preeclampsia is a common disorder of pregnancy characterized by endothelial dysfunction. It may be life-threatening for the mother and fetus in severe cases. Dysregulation of the complement system has been suggested to predispose women to preeclampsia. Complement is part of the innate and adaptive immune systems and potentially capable of causing inflammation and tissue damage. Membrane cofactor protein MCP (CD46) is among the potent complement regulators that have recently been linked to a severe form of preeclampsia with or without an underlying autoimmune phenotype. Mutations in CD46 predispose to thrombotic microangiopathy with endothelial cell dysfunction. The exome of CD46 were sequenced in 95 Finnish women with severe preeclampsia. Genetic variations discovered in the full exome were compared to those observed in 95 control women who did not develop preeclampsia. Because A304V (rs35366573) was associated with preeclampsia in one previous study, we sequenced the transmembrane region including the A304V variant and part of the cytoplasmic tail in 95 additional controls. We did not discover any association between A304V or other CD46 SNPs and preeclampsia. This study describes a carefully characterized cohort of severely preeclamptic Finnish women and found no potentially predisposing variants in CD46. However, it is possible that other genetic components of the complement system may affect the pathogenesis of severe preeclampsia and related diseases.

    Anatomic and physiologic adaptations within the renal system during pregnancy are significant. Alterations are seen in renal blood flow and glomerular filtration, resulting in changes in normal renal laboratory values. When these normal renal adaptations are coupled with pregnancy-induced complications or preexisting renal dysfunction, the woman may demonstrate a reduction of renal function leading to an increased risk of perinatal morbidity and mortality. This article will review normal pregnancy adaptations of the renal system and discuss common pregnancy-related renal complications.

    Renal angiomyolipomas (RAML) are uncommon benign renal tumours that are associated with a tendency to rupture resulting in sometimes-torrential retroperitoneal hemorrhage as the Wunderlich syndrome or as severe potentially exsanguinating hematuria. When hemorrhage from RAML occurs in pregnancy it presents a unique challenge requiring timely and appropriately adapted intervention with the goal of preventing fatality, preserving renal function as well as preventing fetal loss if possible. We report the management of severe bleeding from RAML in pregnancy and highlight the need to adopt a management strategy that suits the practice environment and offers the patient standard and enduring care.

    Opioid maintenance therapy (OMT) is generally recommended for pregnant opioid-dependent women. Previous studies investigating the long-term effects of OMT on children's cognitive development found that children of women in OMT have an increased risk of developing deficits in motor and visual perceptual skills, which are important aspects of the mirror neurone system (MNS), a complex neural circuit involved in learning and social interactions. The aim of the current study was to investigate aspects of the MNS in children of women in OMT. A 2 (control group versus OMT group) × 2 (human versus mechanic) mixed factorial design. The Cognitive Developmental Research Unit at the University of Oslo, Norway. Fifteen children of women in OMT and 15 non-exposed children participated. Goal-directed eye movements were recorded using a Tobii 1750 eye tracker. Neurocognitive tests were employed to map children's cognitive development. The OMT group made fewer proactive goal-directed eye movements [mean = -37.73, standard deviation (SD) = 208.56] compared to the control group (mean = 181.47, SD = 228.65), F((1,28)) = 7.53, P = 0.01, η(2) = 0.21. No differences were found on tests of visual perception or goal understanding. Use of opioid maintenance therapy during pregnancy appears to be associated with impaired goal-directed eye movements in the 4-year-old infant which may affect later social adjustment adversely. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    Full Text Available Visual obscurations are common during pregnancy. The ocular effects of pregnancy may be physiological,pathological or may be modifications of pre-existing conditions. While most of the described changes are transient in nature, others extend beyond delivery and may lead to permanent visual impairment. Also, pregnancy can affect vision through systemic disease that are either specific to the pregnancy itself or systemic diseases that occur more frequently in relation to pregnancy. Neuro-ophthalmological disorders should be kept in mind in pregnant women presenting with visual acuity or field loss. Therefore, it is important to be aware of the ocular changes in pregnancy in order to counsel and advice women who currently are, or are planning to become pregnant.

    The effect of insulin was investigated on ovarian follicle population, ovulation rate, hormonal profiles and embryo/fetal development during pregnancy using transrectal ultrasonography in goats. Twelve goats synchronized in estrus were selected for the experiment. They were divided into two groups, viz. (untreated control, n=6) and (insulin treated, n=6). In treated group long acting bovine insulin was administered @ 0.2IU/kg body weight subcutaneously for three consecutive days, i.e. days 7-9 of estrous cycle. Thereafter, weekly single injection of insulin was continued for rest of the experiment. However, in control group only normal saline was injected as placebo. Breeding was allowed by natural service in both the groups. The does were subjected to B-mode transrectal ultrasound scanning of ovary and uterus weekly up to 120 and 98 days of gestation, respectively. Blood samples were collected weekly up to 135 days of gestation for the estimation of estradiol 17beta and progesterone (P4). The result revealed no difference in mean number of total follicles between the control and insulin treated groups. The diameter of medium follicle did not differ where as diameter of large follicle was comparatively higher in treated than control goats. The average number of corpus luteum (CL) was higher in insulin treated group as compared to control (1.66 vs. 1.16). However, the number as well as mean diameter of CL did not differ significantly between treated and control group. Serum concentrations of estradiol 17beta and progesterone were significantly (P0.05) in treated animals. The results demonstrated beneficial effect of exogenous administration of insulin on ovarian function and twinning percentage in goats.

    Over the last few decades, reproductive medicine has observed an improvement in the management and outcome of pregnancy in connective tissue diseases, such as systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). However, pregnancy and related issues remain a challenge in these patients. In routine clinical practice, health professionals dealing with SLE and APS need to consider the numerous aspects of the reproductive life of their patients, such as pregnancy, family planning, fertility, contraception, cancer surveillance, and menopause. The new European League Against Rheumatism recommendations for women's health and family planning reflect the need for a novel approach to communication in the patient-physician relationship. Preconception counseling is essential to ensure optimal pregnancy outcomes through a careful risk stratification involving disease activity, organ involvement, autoantibody profile, use of drugs, and previous pregnancy outcomes, as well as to ensure better preventive and therapeutic strategies to limit complications. In patients with stable/inactive disease and low risk of thrombosis, adequate hormonal contraception and menopausal replacement therapy should be recommended. Assisted reproductive techniques can be safely used in these patients, but anticoagulation or low-dose aspirin (or both) should be added in those with positive antiphospholipid antibody titers. All menstruating women should be counseled on the possibility to preserve fertility with gonadotropin- ‑releasing hormone analogues if receiving alkylating agents. Strict clinical, serological, laboratory, and multidisciplinary monitoring during pregnancy is mandatory to early recognize and effectively treat disease flares or obstetric complications. Doppler ultrasonography and fetal biometry should be regularly performed, especially in the second and third trimesters. Physicians should recommend screening for cervical dysplasia related to human papillomavirus

    Asthma exacerbations are common during pregnancy with a prevalence as high as 51.9% among women with severe asthma. To compare the treatment of asthma exacerbations in an acute-care setting during and outside of pregnancy. We formed a cohort of women who sought medical care for an asthma exacerbation at a teaching hospital during or in the year preceding pregnancy, between 1998 and 2008. An exacerbation was composed of one or more medical encounters in an acute-care setting (hospital-based outpatient clinic, emergency department, or during hospitalization). Data were retrieved from medical charts and health administrative databases. We compared the use of systemic corticosteroids (SCSs) during and outside of pregnancy with a Cox proportional hazards model. The cohort was formed of 39 women who had 40 exacerbations during and 39 exacerbations outside of pregnancy. Use of SCSs to treat exacerbations was less frequent (adjusted hazard ratio: 0.51; 95% CI: 0.31-0.84) during pregnancy. Moreover, upon the first medical encounter related to the exacerbation, SCSs, when administered, were given less frequently to women when pregnant than when non-pregnant (83% vs. 100%). The SCS prescription was filled at the community pharmacy 65% and 67% of the time when it was prescribed at discharge to women when pregnant than when non-pregnant, respectively. We observed a reduced and delayed use of SCSs for the treatment of asthma exacerbations in women when pregnant than when non-pregnant, with similar numbers of women in both conditions filling their SCSs prescription in pharmacies.

    Antiphospholipid syndrome is an auto-immune disorder characterised by recurrent thrombosis, pregnancy losses and the presence of antiphospholipid antibodies. Although it was initially considered an auto-immune coagulopathy, it is now clear that it is a complex and systemic disease. A large number of manifestations in different organs and tissues (cardiac, pulmonary, neurological, renal, cutaneous, haematologic, gastrointestinal, ocular, skeletal and endocrinologic) have been described in these patients. A small group of patients can have a microvascular involvement, which is the most common pathological finding in patients affected by the catastrophic variant of the syndrome. A strong relationship exists between the antiphospholipid syndrome and systemic lupus erythematosus, as demonstrated by common clinical, serological and genetic features and by the few but possible cases evolving from the first disease into the second one over years. Finally, the systemic nature of the antiphospholipid syndrome and the understanding of the mechanisms of antiphospholipid-mediated damage suggest a role of immunomodulation beyond anticoagulation in the therapeutic approach to the disease.

    In Mexico, 20% of the annual births are presented in women younger than 20 years old. Pregnancy in adolescents puts at risk mother and child health. This risk is major while the woman is younger, especially when the social and economic conditions are not favorable, which is decisive in later psychosocial development. It has been pointed out that the youths with low education, with minor academic and laboral expectations, with low self-esteem and assertiveness, tend to begin early their active sexual life, to use less frequently contraceptives, and in the case of younger women, to be pregnant, with the risk of abortion because they cannot to make the best decision. It is important to take into account the social context and the special characteristics of the family to understand situation of adolescent at risk of pregnancy.

    Diagnosis of guinea pig pregnancy by the inhibition hemagglutination test used to detect chorionic gonadotrophin in urine showed to be unreliable after the 57% false positive and 3% false negative results obtained over 79 urine samples tested. On the other hand, by comparing the cell morphology of about 60 vaginal smears taken from 20 non-pregnant guinea pigs, stained by a Papanicolaou modified technique, the 4 estrous cycle stages were characterized. The subsequent study of many vaginal smears taken from 15 pregnant guinea pigs showed no pathognomic cells but a picture where 60-70% proestrus and 40-30% diestrus cells appeared. This proestrus-diestrus (Pd) picture was accepted as typical for pregnancy, because it showed up in every pregnant guinea pig lasting all the gestation period, changing only after delivery or abortion. Fecundation does not change the estrous cycle sequence which, as it was proved, progressed normally until it reached this Pd picture. Therefore, the persistence of a Pd picture during +/- 6 days should be considered as diagnosis for pregnancy; when estrus has been detected a Pd picture 12-14 days post estrus as prognosis, and at 16-19 days post-estrus as diagnosis for pregnancy. This cytologic assay proved to be reliable. Besides, once cell characterization has been performed, the staining procedure can be substituted by a direct observation of wet specimen, saving time without loosing accuracy.

    Pregnancy is identified as a sensitive period of increased risk for poor oral health among mothers and offspring. Subsequently, both medical and dental associations have re-endorsed consolidated, inter-professional guidelines promoting oral health during pregnancy. The objective was to explore prenatal and oral health providers' information, motivation and practice behaviors related to oral health during pregnancy. Twenty-two in-depth interviews were conducted with prenatal and oral health providers based on the Information-Motivation-Behavioral Skills Model. Data were analyzed using the constant comparative method in NVivo 10. Providers held variable knowledge with regards to identified oral-systemic connections and implications. Most providers were unaware of the guidelines; however, some oral health providers reported avoiding specific treatment behaviors during this period. Motivation to address oral-systemic health during pregnancy included: prevention; healthy pregnancy/birth outcomes; patient's complaint/question as cue to action; comprehensive, patient-centered, and family-centered care; ethical duty; and professional governing body. Oral health providers reported assessing, educating, and communicating with patients about oral health issues; whereas prenatal providers rarely addressed oral health but reported signing approval forms to receive such care. A few oral health providers highlighted lifecourse implications and the need for family-centered care when addressing poor oral health among pregnant patients. Findings suggest gaps in oral health prevention information and behaviors among prenatal and oral health providers. Future efforts should examine effective dissemination and implementation strategies that translate evidence-based guidelines into clinical practice, with the ultimate goal of improve oral-systemic health among women and their offspring across the lifecourse.

    2008-01-01

    Cooperative system bridges comprise several basic structures that act jointly to improve structural characteristics. We delved into the historical development of cooperative system bridges. Cooperative systems are classified as different-load cooperative systems and same-load cooperative systems by distinguishing the modes of load distribution. For different-load cooperation, individual basic structures are at different positions in the direction along bridge axis and carry the loads separately. While for same-load cooperation, all basic structures overlap in geometrical locations and support the entire loads conjointly. The choosing of span ratios between basic structures, the design of connections of different-load cooperative systems were discussed as well as optimizations of relative rigidity for same-load cooperative systems which greatly influence structural characteristics. The general situation and several structural measurements of several cooperative bridges were demonstrated. This information can assist engineers in developing their concepts in cooperative systems and can lead to more efficient and economical cooperative bridges.

    Science.gov (United States)

    Larcher, Vic; Brierley, Joe

    2016-10-01

    Adolescents need safe effective drugs that have undergone ethically approved testing in clinical trials; such studies often require pregnancy testing in 'women of childbearing age' which includes children/adolescents. There is a lack of consistent standard operating procedures for pregnancy testing in these individuals, in either research or clinical (ie, both preprocedure and clinical emergency) settings. Some harmonisation between a selective or universal testing approach based on a risk analysis of the trial drug or procedure would seem sensible. The need for pregnancy testing and the reasons for the method chosen (universal or selective) should be clearly defined in the research protocol. Research ethics committees (RECs) need to satisfy themselves that the selection of subjects to be tested, the procedures for obtaining consent and the respecting of the young person's confidentiality are appropriate and that management of any positive tests are in accord with local safeguarding policies and procedures. Researchers should have core competencies necessary to manage sensitive questioning and child safeguarding training. Clinical trials of medicinal product (CTIMP) pregnancy testing in females 13-15 years of age requires parental consent and the child's active involvement in the decision-making process ('assent') the implications of a positive test should be discussed in advance Children under 13 years should not normally be subject to pregnancy testing in CTIMPs, unless there are exceptional circumstances, for example, a trial of contraceptive agents of a high teratogenicity risk, as reviewed by a specialist paediatric REC. We analyse the ethical, legal and practical aspects of this issues and supply guidance to support those involved.

    2014-06-01

    To describe response rates and characteristics associated with response to the Pregnancy Risk Assessment Monitoring System study in Ireland (PRAMS Ireland). Using hospital discharge records of live births at a large, urban, obstetric hospital, a sampling frame of approximately 2,400 mother-infant pairs were used to alternately sample 1,200 women. Mothers’ information including name, address, parity, age and infant characteristics such as sex and gestational age at delivery were extracted from records. Modes of contact included an invitation letter with option to opt out of the study, three mail surveys, a reminder letter and text message reminder for remaining non-respondents. Sixty-one per cent of women responded to the PRAMS Ireland survey over a 133 day response period. Women aged <30, single women, multiparous women and women with a preterm delivery were less likely to respond. Women participating in PRAMS Ireland were similar to the national birth profile in 2011 which had a mean age of 32, were 40 % primiparous, 33 % single or never married and had a 28 % caesarean section rate. Survey and protocol changes are required to increase response rates above recommended Centers for Disease Control and Prevention (CDC) thresholds of 65 % within the recommended 90 day data collection cycle. Additional efforts such as stratification and over-sampling are required to increase representativeness among hard to reach groups such as younger, single and multiparous women before expanding the project to an ongoing, national surveillance system in Ireland.

    Autonomic nervous system activity was studied to evaluate the physical and mental state of women with unexplained recurrent pregnancy loss (RPL). Heart rate variability (HRV) is a measure of beat-to-beat temporal changes in heart rate and provides indirect insight into autonomic nervous system tone and can be used to assess sympathetic and parasympathetic tone. We studied autonomic nervous system activity by measuring HRV in 100 women with unexplained RPL and 61 healthy female volunteers as controls. The degree of mental distress was assessed using the Kessler 6 (K6) scale. The K6 score in women with unexplained RPL was significantly higher than in control women. HRV evaluated on standard deviation of the normal-to-normal interval (SDNN) and total power was significantly lower in women with unexplained RPL compared with control women. These indices were further lower in women with unexplained RPL ≥4. On spectral analysis, high-frequency (HF) power, an index of parasympathetic nervous system activity, was significantly lower in women with unexplained RPL compared with control women, but there was no significant difference in the ratio of low-frequency (LF) power to HF power (LF/HF), an index of sympathetic nervous system activity, between the groups. The physical and mental state of women with unexplained RPL should be evaluated using HRV to offer mental support. Furthermore, study of HRV may elucidate the risk of cardiovascular diseases and the mechanisms underlying unexplained RPL. © 2014 The Authors.

    The Obstetrics Division of Schio Hospital has introduced the computerised management of pregnancy and birth in order to obtain standard and complete data on both pregnancy, wherever the woman is followed, and birth, whenever this occurs and by which ever team the woman is assisted. Computerised management is possible on account of the low costs, the availability of large ranges of software and the ability to transfer data. It is based on the presumption that on being admitted to hospital all women must possess a clinical record of their pregnancy stating the obstetrical risk. The programme GEST-PART contains a 6-letter password which gives access to the utility menu.

  17. Business system: Sustainable development and anticipatory system

    Full Text Available The existence and development of humankind depends mainly upon the co-ordinated operation of all areas and levels of human activity. However, in theory and in practice there is no model of operation, which would provide a harmonized and target oriented development. A partial solution is offered by sustainable development, which tries to define and carry out common goals of mankind with a harmonized implementation of human activities at all levels of its living and behaviour. Companies belong to central institutions of modern society which essentially co–create the sustainability of society. The company’s endeavour by simulation to prepare models of their goals concerning their internal and external environment. On the base of systemic treatment, we can define companies as business system, which can survive in a log-run only on the basis of sustainable development. The business system can also be supported by the application of the anticipatory systems. The anticipatory systems can be, in this sense, understood as an entity of the methodological approach, techniques and modes of work. Their characteristics have, a direct impact on the determination of goals, on the orientation of operation, and hence on the achievement of the business system results.

    Expression of mRNAs encoding interleukin-1β (IL-1β), IL-1β receptor I (IL-1RI), IL-1 receptor accessory protein (IL-1RAcP) and IL-1 receptor antagonist (IL-1Ra), as well as synthesis of IL-1β and IL-1RI proteins, were examined in the corpus luteum (CL) during critical stages of CL activity on days 10-16 of pregnancy and 2-16 of the estrous cycle. Luteal cells were cultured in vitro with IL-1β, and the effect on release of steroid hormones was determined. Expression of the IL-1β system in the CL changed significantly during pregnancy and the estrous cycle. IL-1β, IL-1RI, and IL-1Ra mRNA levels were elevated on days 12-13, whereas IL-1RAcP mRNA was increased on days 15-16 of pregnancy. In cyclic CL, expression of IL-1β, IL-1RI, and IL-1RAcP mRNAs was increased on days 12-13. IL-1β and IL-1RI protein were highest in the CL on days 10-11 and 8-11 of pregnancy and the estrous cycle. Luteal cells harvested from gravid and cyclic CL produced IL-1β in vitro. IL-1β increased progesterone and estradiol-17β (E2) release by luteal cells on days 10-16 and 10-11 of pregnancy, respectively and on days 2-11 of the estrous cycle. IL-1β decreased the level of E2 produced by regressed CL (days 15-16). Expression of the IL-1β system in CL and IL-1β secretion from luteal cells changed depending on the status of the CL. These data show that IL-1β may be involved in intraluteal, luteotrophic regulation of CL functions in gravid and cyclic pigs.

    This study investigated the effects of hormonal status and metabolic changes of restricted ewes during late pregnancy on the ovine fetus growth and development. One hundred Mongolian ewes, synchronized for oestrus and mated, were divided into three groups and offered 0.175 MJME·kgw-0.75·d-1 (Restricted Group 1, RG1), 0.33 MJME·kgw-0.75·d-1 (Restricted Group 2, RG2) and ad libitum access to feed (Control Group, CG) during their late pregnancy respectively. The results suggested that with the supply of exogenous energy decreasing during late pregnancy, maternal body weight and net body weight loss in RG2 and RG1 were lower than those of CG (P<0.01). The insulin and IGF-1 concentrations of ewes in RG2 and RG1 tended to be lower than those of CG (P>0.05), but the GH concentrations in RG2 and RG1 were enhanced and there was significant difference between RG1 and CG on d 120 of gestation (P<0.05). The glucose concentration of ewes in RG2 and RG1 was decreased throughout the feed restriction period, and the differences were observed between RG1 and CG on d 120 of gestation (P<0.05). In addition, the nonesterified fatty acid (NEFA) and total amino acid (TAA) concentrations of ewes in RG2 tended to increase, but there was no significant difference (P>0.05). However, the NEFA and FAA concentrations of ewes in RG1 were reduced from d 90 to d 120 of gestation, then enhanced from d 120 to d 140 of gestation. During the late pregnancy, with the supply of nutrition decreasing, the negatively physiological and biochemical maternal reactions to restriction became worse, which significantly reduced the average lamb birth weight and daily growth rate of fetus in RG2 (P<0.05) and RG1 (P<0.01).

    2015-09-01

    The management of lupus nephritis in pregnancy presents a diagnostic and therapeutic challenge for providers. Pregnancy creates a series of physiologic changes in the immune system and kidney that may result in an increased risk of disease flare and adverse maternal and fetal outcomes, such as preeclampsia, fetal loss, and preterm delivery. Conception should be delayed until disease is in remission to ensure the best pregnancy outcomes. Maternal disease activity and fetal well-being should be monitored closely by an interdisciplinary team, including obstetricians, rheumatologists, and nephrologists throughout pregnancy. Careful attention must be paid to the dosing and potential teratogenicity of medications.

    Ascertaining the meaning of teenage pregnancy for teenagers and their immediate families. This was an analytical, cross-sectional, exploratory, qualitative study. Data was obtained through in-depth interviews with 10 pregnant teenagers and their immediate families, plus a focus group involving another 12 pregnant teenagers. Analysis by category revealed a tenuous limit between adolescents' narrative identity and a lack of such identity and identity based on the concept of family. Pregnancy provokes a series of responses within families, including fear in a pregnant adolescent and her partner, disappointment on the part of the parents, social isolation and eventual acceptance and redefinition of such pregnancy. Pregnancy can provide the means for an adolescent to redress a deficit in her emotional needs, such condition keeping the family together at the expense of a teenager's emancipation and may represent an intergenerational legacy.

    Full Text Available The prevalence of smoking during pregnancy in Ribeirão Preto, a rich Brazilian city, was significantly higher (21.4% than in São Luís (5.9%, a less developed city. To assess which variables explain the difference in prevalence of smoking during pregnancy, data from two birth cohorts were used, including 2846 puerperae from Ribeirão Preto, in 1994, and 2443 puerperae from São Luís, in 1997/98. In multivariable analysis, risk of maternal smoking during pregnancy was higher in São Luís for mothers living in a household with five or more persons (OR = 1.72, 95%CI = 1.12-2.64, aged 35 years or older (OR = 1.98, 95%CI = 0.99-3.96, who had five or more children (OR = 2.10, 95%CI = 1.16-3.81, and whose companion smoked (OR = 2.20, 95%CI = 1.52-3.18. Age of less than 20 years was a protective factor (OR = 0.55, 95%CI = 0.33-0.92. In Ribeirão Preto there was association with maternal low educational level (OR = 2.18, 95%CI = 1.30-3.65 and with a smoking companion (OR = 3.25, 95%CI = 2.52-4.18. Receiving prenatal care was a protective factor (OR = 0.24, 95%CI = 0.11-0.49. Mothers from Ribeirão Preto who worked outside the home were at a higher risk and those aged 35 years or older or who attended five or more prenatal care visits were at lower risk of smoking during pregnancy as compared to mothers from São Luís. Smoking by the companion reduced the difference between smoking rates in the two cities by 10%. The socioeconomic variables in the model did not explain the higher prevalence of smoking during pregnancy in the more developed city.

    Full Text Available Thyroid cancer is the second most common cancer diagnosed during pregnancy after breast cancer. The goal of management is to control malignancy and prevent maternal and fetal complications as a result of maternal hypothyroidism. The role of female sex hormones as an etiologic factor was investigated, with no clear association. Pregnancy can cause an increase in size of a previously existed thyroid nodule through the structural similarity between TSH and BHCG, and the normally expressed estrogen receptors on thyroid gland cells. Effect of pregnancy on development and prognosis of differentiated thyroid malignancies (papillary and follicular has also been studied. The prognosis of thyroid cancer is not worse in patients diagnosed during pregnancy or those who got pregnant after curative treatment. Termination of pregnancy is not indicated at all, surgery can be delayed till after delivery except in rapidly growing aggressive tumors. While radioactive iodine ablation is absolutely contra-indicated, the new systemic therapies are not well studied during pregnancy. However, almost all these new agents are classified as FDA category C or D and are better to be avoided. The effect of pregnancy on other types of thyroid cancer (medullary and anaplastic thyroid tumors is not well studied because of very low incidence with pregnancy. The endocrinological management of thyroid cancer during pregnancy is of utmost importance. The hypothyroidism after total thyroidectomy can cause fetal hypothyroidism. Therefore, the management of thyroid cancer related to pregnancy needs a multidisciplinary team.

    Full Text Available Teratogenicity and developmental abnormalities in the offspring of female rats that ingested ethanol extract of Neem plants during pregnancy and lactation period were assessed. Twenty-four female Wistar rats were randomly distributed in control group and in three experimental groups and treated during the 4th, 5th, and 6th day of pregnancy. After birth, the lactating females received, by gavage, 65, 135 and 200 mg kg-1 of Neem ethanol extract, during 15 days. Results show, there was no significant difference in body mass index of neonatal rats in the 4 groups evaluated, whereas mean rate of offspring survival was 79.4%. Hair growth, incisor teeth eruption, ear detachment, eyelid opening, and spontaneous ambulation were similar for all groups. Likewise, physical development and development of motor activity, ambulation, and postural reflexes were similar for all groups. The administration of Neem ethanol extract did not cause any reproductive or systemic toxicity in animals. Results show that, Neem ethanol extract safe at doses 65, 135 and 200 mg kg-1 in pregnant or lactating rats.

    Sleep disordered breathing (SDB is very common during pregnancy, and is most likely explained by hormonal, physiological and physical changes. Maternal obesity, one of the major risk factors for SDB, together with physiological changes in pregnancy may predispose women to develop SDB. SDB has been associated with poor maternal and fetal outcomes. Thus, early identification, diagnosis and treatment of SDB are important in pregnancy. This article reviews the pregnancy-related changes affecting the severity of SDB, the epidemiology and the risk factors of SDB in pregnancy, the association of SDB with adverse pregnancy outcomes, and screening and management options specific for this population.

    Full Text Available Ayahuasca is a hallucinogenic beverage prepared by the decoction of plants native to the Amazon Basin region. The beverage has been used throughout the world by members of some syncretic religious movements. Despite the recent legalization of ayahuasca in Brazil for religious purposes, there is little pre-clinical and clinical information attesting to its safety, particularly in relation to the use during pregnancy. The aim of the current work was to determine the effects of perinatal exposure to ayahuasca (from the 6th day of pregnancy to the 10th day of lactation on physical, reflexology and neurobehavioral parameters of the Wistar rat offspring. The offspring showed no statistically significant changes in the physical and reflexology parameters evaluated. However, in adult rats, perinatally exposed to ayahuasca, an increase in frequency of entries in open arms in elevated plus-maze test, a decrease in total time of interaction in social interaction test, a decrease in time of latency for the animal to start swimming and a decrease of the minimum convulsant dose induced by pentylenetetrazol were observed. In conclusion, our results showed that the use of ayahuasca by mothers during pregnancy and lactation reduced the general anxiety and social motivation of the rat offspring. Besides, it promoted a higher sensitivity for initiation and spread of seizure activity.

  14. The developmental psychopathology of perinatal depression: implications for psychosocial treatment development and delivery in pregnancy.

    Goodman, Sherryl H; Dimidjian, Sona

    2012-09-01

    Taking a developmental psychopathology perspective, our objective was to identify ways in which psychosocial treatment of depression during pregnancy may be enhanced. We first consider the state of evidence on psychosocial interventions for antenatal depression, next define key developmental psychopathology concepts that are relevant to antenatal depression, and finally discuss implications for clinical practice and research. We found a limited, but promising, evidence base for effective psychosocial interventions for depression during pregnancy. Examining antenatal depression from a developmental psychopathology perspective revealed suggestions for improving treatment. A developmental psychopathology perspective suggests that treatment of depression during pregnancy may be improved by attention to the continuum of depression, from subclinical to severe major depressive disorder; personalized care based on individual women's pattern of risk and resilience factors and correlated risks; consideration of the potential benefits of treating the couple's relationship, the mother's qualities of parenting, and infants' and children's mental health needs; and, including a detailed understanding of the developmental pathways to antenatal depression for each patient in treatment planning.

  15. The Role of Nicotine in the Effects of Maternal Smoking during Pregnancy on Lung Development and Childhood Respiratory Disease. Implications for Dangers of E-Cigarettes.

    Spindel, Eliot R; McEvoy, Cindy T

    2016-03-01

    Use of e-cigarettes, especially among the young, is increasing at near-exponential rates. This is coupled with a perception that e-cigarettes are safe and with unlimited advertising geared toward vulnerable populations, the groups most likely to smoke or vape during pregnancy. There is now wide appreciation of the dangers of maternal smoking during pregnancy and the lifelong consequences this has on offspring lung function, including the increased risk of childhood wheezing and subsequent asthma. Recent evidence strongly supports that much of the effect of smoking during pregnancy on offspring lung function is mediated by nicotine, making it highly likely that e-cigarette use during pregnancy will have the same harmful effects on offspring lung function and health as do conventional cigarettes. In fact, the evidence for nicotine being the mediator of harm of conventional cigarettes may be most compelling for its effects on lung development. This raises concerns about both the combined use of e-cigarettes plus conventional cigarettes by smokers during pregnancy as well as the use of e-cigarettes by e-cigarette-only users who think them safe or by those sufficiently addicted to nicotine to not be able to quit e-cigarette usage during pregnancy. Thus, it is important for health professionals to be aware of the risks of e-cigarette usage during pregnancy, particularly as it pertains to offspring respiratory health.

    Background Data on long-term maternal outcomes in patients with systemic lupus erythematosus (SLE) are lacking. The study aimed to explore the relationships among SLE, pregnancy, outcomes of end-stage renal disease (ESRD), and overall mortality. Methods We established a retrospective cohort study consisting of four cohorts: pregnant (case cohort) and nonpregnant SLE patients, as well as pregnant and nonpregnant non-SLE patients. One case cohort and three comparison cohorts were matched by age at first pregnancy and index date of pregnancy by using the Taiwan National Health Insurance Research Dataset. All study subjects were selected based on the index date to the occurrence of ESRD or overall death. Cox proportional hazard regression models and Kaplan–Meier curves were used in the analysis. Results SLE pregnant patients exhibited significantly increased risk of ESRD after adjusting for other important confounders, including immunosuppressant and parity (HR = 3.19, 95% CI: 1.35–7.52 for pregnant non-SLE; and HR = 2.77, 95% CI: 1.24–6.15 for nonpregnant non-SLE patients). No significant differences in ESRD incidence were observed in pregnant and nonpregnant SLE patients. Pregnant SLE patients exhibited better clinical condition at the baseline and a significantly lower risk of overall mortality than nonpregnant SLE patients. Conclusions Our data support current recommendations for SLE patients to avoid pregnancy until disease activity is quiescent. Multicenter recruitment and clinical information can be used to further examine the association of SLE and ESRD (or mortality) after pregnancy. PMID:27992461

    High multivitamin (HV) content in gestational diets has long-term metabolic effects in rat offspring. These changes are associated with in utero modifications of gene expression in hypothalamic food intake regulation. However, the role of fat-soluble vitamins in mediating these effects has not been explored. Vitamin A is a plausible candidate due to its role in gene methylation. Vitamin A intake above requirements during pregnancy affects the development of neurocircuitries involved in food intake and reward regulation. Pregnant Wistar rats were fed AIN-93G diets with the following content: recommended multivitamins (1-fold multivitamins: RV), high vitamin A (10-fold vitamin A: HA) or HV with only recommended vitamin A (10-fold multivitamins, 1-fold vitamin A: HVRA). Body weight, food intake and preference, mRNA expression and DNA methylation of hippocampal dopamine-related genes were assessed in male offspring brains at different developmental windows: birth, weaning and 14weeks postweaning. HA offspring had changes in dopamine-related gene expression at all developmental windows and DNA hypermethylation in the dopamine receptor 2 promoter region compared to RV offspring. Furthermore, HA diet lowered sucrose preference but had no effect on body weight and expression of hypothalamic genes. In contrast, HVRA offspring showed only at adulthood changes in expression of hippocampal genes and a modest effect on hypothalamic genes. High vitamin A intake alone in gestational diets has long-lasting programming effects on the dopaminergic system that are further translated into decreased sucrose preference but not food intake.

    Endocrine disrupting chemicals with estrogenic activity play an important role as obesogens. However, studies investigating the most potent natural estrogen, estradiol-17β (E2), at low dose are lacking. We examined endocrine and physiological parameters in gilts receiving distinct concentrations of E2 during pregnancy. We then investigated whether adverse effects prevail in progeny due to a potential endocrine disruption. E2 was orally applied to gilts during the entire period of pregnancy. The concentrations represented a daily consumption at the recommended ADI level (0.05 μg/kg body weight/day), at the NOEL (10 μg/kg body weight/day) and at a high dosage (1000 μg/kg body weight/day). Plasma hormone concentrations were determined using enzyme immuno assays. Offspring body fat was assessed by dual-energy X-ray absorptiometry scanning. In treated gilts receiving 1000 μg E2/kg body weight/day we found significantly elevated plasma E2 levels during pregnancy, paralleled by an increased weight gain. While offspring showed similar weight at birth, piglets exhibited a significant reduction in weight at weaning even though their mothers had only received 0.05 μg E2/kg body weight/day. At 8 weeks of age, specifically males showed a significant increase in overall body fat percentage. In conclusion, prenatal exposure to low doses of E2 affected pig offspring development in terms of body weight and composition. In line with findings from other obesogens, our data suggest a programming effect during pregnancy for E2 causative for the depicted phenotypes. Therefore, E2 exposure may imply a possible contribution to childhood obesity. -- Highlights: ► We investigate the potential role of estradiol-17β (E2) as an obesogen. ► We orally apply E2 at the ADI, NOEL and a high dose to gilts during pregnancy. ► Offspring weight is similar at birth but reduced at weaning even after ADI treatment. ► Male offspring only exhibit an increase in overall body fat percentage

    Full Text Available Hormonal, metabolic, hemodynamic, vascular and immunological changes that occur during pregnancy can affect the function of the eye. These changes are commonly transient, but in some cases they may be permanent and have consequences even after childbirth. The ocular effects of pregnancy may be physiological or pathological and can be associated with the development of new ocular pathology or may be modifications of pre-existing conditions. The most common physiological changes are alterations of corneal sensitivity and thickness, decreased tolerance to contact lenses, decreased intraocular pressure, hemeralopia and refractive errors. Possible posterior segment changes include worsening of diabetic retinopathy, central serous chorioretinopathy, increased risk of peripheral vitreochorioretinal dystrophies and retinal detachment. Thus, it should be kept in mind that the presence of any ocular symptoms in a pregnant woman requires ophthalmologic examination and further management. Knowledge of these ocular changes can help to differentiate the physiological changes from ocular manifestation of systemic disease and diseases pertaining to the eye in a pregnant woman. This article explains the effects of ocular changes in pregnancy. [Int J Res Med Sci 2014; 2(1.000: 16-20

    Abstract Physiological changes occur in pregnancy to nurture the developing foetus and prepare the mother for labour and delivery. Some of these changes influence normal biochemical values while others may mimic symptoms of medical disease. It is important to differentiate between normal physiological changes and disease pathology. This review highlights the important changes that take place during normal pregnancy.

    Pregnancy is a vital period where several hyperplasic, hypertrophic processes together with metabolic adaptation and preparation for extra-uterine life take place. Present review accounts for central aspects of nutrition throughout gestation on the embryonic and fetal periods. It is centered in the major changes occurring in fetal pancreas, with special mention to the susceptibility of this main glucose homeostasis organ to support nutritional changes during maturation and development. Studies performed in animal models as human are commented considering the role of maternal nutrition on β-cell mass size, insulin and other pancreatic hormones production, and insulin sensitivity. Details of both the thrifty genotype and phenotype hypothesis are given, indicating that hypo/subnutrition causes metabolic adaptations that permit the future body to grow and develop itself in limited environmental and energetic conditions. The Barker hypothesis is considered suggesting that this metabolic hypothesis is a double-edged sword in the actual abundance World. Lastly the review, taking into account our own research and other papers, analyses less known aspects that relate maternal diet with insulin resistance/sensitivity markers at delivery. Particularly the role of the saturated fatty acid/carbohydrate and omega-6/omega-3 ratios in the frame of maternal diet is reviewed considering the quality of those diets under the Healthy Eating Index and the Adherence to Mediterranean Diet scores and the relationship with insulin resistance profile at birth. Present review ends indicating that nutritional habits should be strongly stated before gestation in order to assure a proper nutrition since the first moment of pregnancy. This will support an adequate fetal and pancreatic growth and development, and in turn, adequate glucose homeostasis during pregnancy and later in life, slowing down or preventing from degenerative diseases related with metabolic syndrome and type 2 diabetes

    Objective: To assess the perinatal and developmental outcomes of assisted reproductive technologies (ART) children born after multifetal pregnancy reduction (MPR).Methods: Twenty-four ART children born after MPR were compared to 9 triplets without MPR, and 24 matched IVF children without MPR and 24 naturally conceived. Mental and psychological development was assessed by Bayley Scales.of Infant. The outcomes compared included perinatal characteristics, body mass index (BMI), mental development index (MDI) and psychomotor development index (PDI).Results: MPR singletons/twins had better neonatal outcomes than non-MPR triplets. Moreover, PDI of the MPR singletons/twins was significantly higher than that of the non-MPR triplets. There were no significantly difference in perinatal characteristics, BMI, MDI and PDI among 24 MPR children, 24 matched IVF children without MPR and 24 matched naturally conceived children.Conclusion: Multifetal pregnancy reduction could improve perinatal outcomes and would not affect physical, mental and psychomotor development for children born after it.

    Management of pregnant women with renal disease involves awareness of, and allowance for, physiological changes including decreased serum creatinine and increased proteinuria. For women with systemic lupus erythematosus (SLE), pregnancy increases likelihood of flare. These can occur at any stage, and are more difficult to diagnose, as symptoms overlap those of normal pregnancy. Renal involvement is no more common in pregnancy. Worsening proteinuria may be lupus flare but differential includes pre-eclampsia. In women with chronic renal disease, pregnancy may accelerate decline in renal function and worsen hypertension and proteinuria, with increased risk of maternal (eg, pre-eclampsia) and fetal (eg, IUGR, IUD) complications, strongly correlating with degree of renal impairment peri-conception. Pregnancy success rate varies from 20% to 95% depending on base-line creatinine. Best outcome is obtained if disease was quiescent for >6 months pre-conception. Women on dialysis or with renal transplants can achieve successful pregnancy but have higher maternal and fetal complication rates. Acute on chronic renal failure can develop secondary to complications such as HELLP and AFLP. Management needs to be by a multidisciplinary team involving physicians and obstetricians, ideally beginning with pre-pregnancy counselling. Treatment of flares includes corticosteroids, hydroxychloroquine, azothioprine, NSAIDs and MME Blood pressure is controlled with methyldopa, nifedipine or hydralazine.

    With the continuous growth of mobile network coverage and unprecedented penetration of mobile devices in the developing world, several mHealth initiatives are being implemented in developing countries. This paper aims to describe requirements for designing and implementing a mobile phone-based communication system aiming at monitoring pregnancy and reducing bottlenecks in communication associated with maternal and newborn deaths; and document challenges and lessons learned. An SMS-based system was developed to improve maternal and child health (MCH) using RapidSMS(®), a free and open-sourced software development framework. To achieve the expected results, the RapidSMS-MCH system was customized to allow interactive communication between a community health worker (CHW)following mother-infant pairs in their community, a national centralized database, the health facility and in case of an emergency alert, the ambulance driver. The RapidSMS-MCH system was piloted in Musanze district, Nothern province of Rwanda over a 12-month period. A total of 432 CHW were trained and equipped with mobile phones. A total of 35,734 SMS were sent by 432 CHW from May 2010 to April 2011. A total of 11,502 pregnancies were monitored. A total of 362 SMS alerts for urgent and life threatening events were registered. We registered a 27% increase in facility based delivery from 72% twelve months before to 92% at the end of the twelve months pilot phase. Major challenges were telephone maintenance and replacement. Disctrict heath team capacity to manage and supervise the system was strengthened by the end of pilot phase. Highly committed CHWs and effective coordination by the District health team were critical enablers. We successully designed and implemented a mobile phone SMS-based system to track pregnancy and maternal and child outcomes in limited resources setting. Implementation of mobile-phone systems at community level could contribute to improving emergency obstetric and neonatal care

    Full Text Available Pregnancy is a special physiological condition where drug treatment presents a special concern because the physiology of pregnancy affects the pharmacokinetics of medications used and certain medications can reach the fetus and cause harm. Total avoidance of pharmacological treatment in pregnancy is not possible and may be dangerous because some women enter pregnancy with medical conditions that require ongoing and episodic treatment (e.g. asthma, epilepsy, hypertension. Also during pregnancy new medical problems can develop and old ones can be exacerbated (e.g. migraine, headache requiring pharmacological therapy. The fact that certain drugs given during pregnancy may prove harmful to the unborn child is one of the classical problems in medical treatment. In 1960′s pregnant ladies who ingested thalidomide gave birth to children with phocomalia. Various other examples of teratogenic effects of drugs are known. It has been documented that congenital abnormalities caused by human teratogenic drugs account for less than 1% of total congenital abnormalities. Hence in 1979, Food and Drug Administration developed a system that determines the teratogenic risk of drugs by considering the quality of data from animal and human studies. FDA classifies various drugs used in pregnancy into five categories, categories A, B, C, D and X. Category A is considered the safest category and category X is absolutely contraindicated in pregnancy. This provides therapeutic guidance for the clinician. This article focuses on various aspects relating to drug use during pregnancy.

    Benign diseases are more common than malignant diseases in pregnant and lactating women. Fibroadenomas are the most commonly identified benign breast tumour in pregnant and lactating women. Pregnancy related breast cancer is defined as breast cancer that occurs during pregnancy or within 1 year of delivery. Its incidence is estimated at 1 in 3000 to 1 in 10 000 pregnancies. Several reproductive factors like age at menarche, age at menopause, age at full-term pregnancy, parity, age at any birth and spacing of pregnancies, breast feeding, characteristics of the menstrual cycle, infertility, spontaneous and induced abortions, characteristics of the menstrual cycle and infertility are some of the factors that have been incriminated as risk factors for breast cancer. We sought to describe the predominant breast pattern, sonographic array of pregnancy related breast diseases in women referred to the breast imaging unit in the department of Radiology at the University College Hospital, Ibadan south west Nigeria. Socio-demographic characteristics in these women were also evaluated. Archived images were reviewed and documented and data was analysed with SPSS version 17 and presented with descriptives. In this descriptive study, we retrospectively retrieved the sonomammographic records of 21 women (pregnant or lactating) referred to and imaged in the department of radiology, University college hospital Ibadan, between 2006 and 2013. Diagnostic breast sonograms performed by MO and ATS; Consultant radiologists with 7-10 years' experience utilized a 7-10 MHz transducer of the General electric GE Logiq P5 machine for the scans. Twenty-one women with ages between 22-42 years (Mean 31.4 ± 5.4 SD) pregnant or lactating were referred to the radiology department for sonomammographic evaluation. Majority of the women were in the 3rd decade. Referral was mainly (11) by family Physicians from the general outpatient clinic, 5 were self-referred, 2 from radiotherapy department, 2 from

    Determination of environmental impacts on reproductive health and specifically on the incidence of early spontaneous abortion requires accurate estimates of the latter. This negative reproductive outcome can be detected by the pattern of elevation and decline of human chorionic gonadotropin (hCG) levels near and shortly beyond the expected time of implantation, requiring daily biomonitoring of hCG levels during the relevant period of the menstrual cycle. Prospective pregnancy studies to assess effects of potentially toxic exposures on human reproductive outcomes can involve up to three menstrual cycles and a huge number of samples in each, for the quantification of the inherently very low hCG levels usually can be determined only in serum. The invasive nature of blood collection, the number of samples needed for the development of prospective studies, and the lack of quantitative methods for the determination of low hCG levels in urine point to the need for collecting urine rather than blood and make it imperative to develop suitable quantitative methods for biomonitoring of very low levels of hCG in urine. This paper describes the development and validation procedures of an automated solid-phase two-site chemiluminescent immunometric assay for the quantification of urinary hCG in early pregnancy and early pregnancy loss. For the validation, both undiluted and diluted urine and control samples have been prepared. From the results, it can be concluded that the assay has a calibration range that extends to 5000 mIU/ml, with a detection limit of approximately 1.2 mIU/ml, practically identical to that found by the IMMULITE 2000 manufacturer's validation study. The intra- and inter-assay precision ranges up to a maximum of around 7%, meaning that the practical limit for functional sensitivity can be established as low as 10%. This means that the immunoassay from DPC can identify, with relatively high confidence, non-pregnant women and the typical "rise and fall" pattern

    Cervical varix is a rare cause of obstetric hemorrhage which needs accurate diagnosis and prompt management because the lesion may be associated with preterm delivery and maternal complications. Our patient was diagnosed with cervical varix and vaginal bleeding at 32 weeks' gestation, using trans vaginal ultrasound and MRI. Persistent vaginal bleeding and preterm labor led to an emergency cesarean section at 33 weeks' gestation. After delivery, cervical varix was spontaneously resolved in the follow-up trans vaginal ultrasound and CT. We report various radiologic features of cervical varix combined with vaginal bleeding in late pregnancy

    Cloacal dysgenesis sequence (CDS) is a rare congenital anomaly. It is characterised by a smooth perineum with absence of anal and genitourinary orifices, with reported incidence of 1:50,000-250,000 births. Association with bilateral renal agenesis is still rarer and resultant severe oligohydramnios is associated with pulmonary hypoplasia. Only a few cases of CDS with bilateral renal agenesis have been reported in the English language literature, with associated pulmonary hypoplasia as a default phenomenon. We report a case of CDS and bilateral renal agenesis without associated pulmonary hypoplasia in a twin pregnancy, which, to the best of our knowledge, is the second reported case of this amalgamation.

    Full Text Available Background. In conditions with appropriate iodine intake, thyroid gland adapts to changes during pregnancy without any consequences. Fetal need for thyroid hormones in the first trimester is directly connected with transplacental transport of thyroid hormones. Fetal synthesis of thyroid hormones depends on availability of iodine in the feto-placental unit. Hypo- and hyperthyroidism during pregnancy are risk factors for pregnant woman and for normal development of fetus and child.Conclusions. Pregnant women with appropriately treated thyroid diseases have the same outcome of pregnancy as healthy women, and neuroendocrinological development of children is not impaired. If the disease is unrecognized or untreated, complications of pregnancy and delivery occur more frequently. Therefore, timely recognition and treatment of the diseases with appropriate drugs during pregnancy and, also, after delivery is very important.

    Past studies have focused on aggregate lupus disease activity during pregnancy and have produced conflicting results. Our study evaluated lupus activity based on involvement of five specific organ systems during the six months prior to conception and during pregnancy. We assessed 147 pregnancies among 113 women followed at Brigham and Women's Lupus Center, 1990-2013. Organ-specific activity included hematologic disorder, nephritis, skin disease, arthritis, and serositis. We hypothesized that the presence of organ-specific activity six months prior to conception would increase the risk for that same type of activity during pregnancy. Our study population was 68% white; 100% had a positive ANA and 30% had a history of nephritis. Among women with organ-specific lupus activity during the six months before conception, the crude odds for the same type of activity during pregnancy was 7.7- to 32.5-fold higher compared to women without that type of activity immediately before conception. An adjusted logistic regression model also indicated significantly higher odds of organ-specific activity during pregnancy if that type of activity were present six months before conception. Approaching lupus based on specific organ systems may be a useful way for women and their physicians to consider the potential risk for disease activity during pregnancy.

    The aim of study was to evaluate the effects of nebivolol, a cardioselective beta-1 adrenergic receptor blocker of the third generation with vasodilatory properties, vs. bisoprolol on the genital circulation, uterine vasculature, fetal growth and postnatal development in pregnant Wistar rats. Non invasive measurements of systolic and diastolic blood pressure (SBP and DBP) and heart rate (HR), and invasive measurement of genital blood flow (GBF) were taken in pregnant rats, by tail cuff and transonic probe methods respectively, after an oral treatment by gastric gavage with nebivolol (8mg/kg/day) or bisoprolol (10mg/kg/day) from day 11 to day 18 of pregnancy. Other morphometrical and histological measurements were performed on the ovarian and uterine arteries to evaluate the effect of nebivolol on the uterine vasculature. Furthermore, postnatal mortality and pup growth were recorded. The data demonstrated that nebivolol (compared with bisoprolol) induced a significant decrease in SBP, HR and GBF while DBP remained unchanged. Moreover, nebivolol increased the diameter and the length of ovarian and uterine arteries and the number of uterine artery segmental branches. The results also showed that the body weight gain of newborns in the nebivolol group was significantly lower vs. bisoprolol and vs. control with a higher mortality rate. The nebivolol action is not only limited to its favorable hemodynamic effects represented by a decrease in blood pressure, but it also produces adverse effects on fetal growth and postnatal development that may limit its therapeutic use in females during pregnancy.

    Data from animal and human studies implicate maternal vitamin D deficiency during pregnancy as a significant risk factor for several adverse outcomes affecting maternal, fetal, and child health. The possible associations of maternal vitamin D status and offspring bone development comprise a significant public health issue. Evidence from randomized trials regarding maternal vitamin D supplementation for optimization of offspring bone mass is lacking. In the same field, data from observational studies suggest that vitamin D supplementation is not indicated. Conversely, supplementation studies provided evidence that vitamin D has beneficial effects on neonatal calcium homeostasis. Nevertheless, a series of issues, such as technical difficulties of current vitamin D assays and functional interplay among vitamin D analytes, prohibit arrival at safe conclusions. Future studies would benefit from adoption of a gold standard assay, which would unravel the functions of vitamin D analytes. This narrative review summarizes and discusses data from both observational and supplementation studies regarding maternal vitamin D status during pregnancy and offspring bone development.

  6. Gestational nanomaterial exposures: microvascular implications during pregnancy, fetal development and adulthood.

    Air pollution particulate matter and engineered nanomaterials are encompassed in the broad definition of xenobiotic particles. While the effects of perinatal air pollution exposure have been investigated, elucidation of outcomes associated with nanomaterial exposure, the focus of this review, is still in its infancy. As the potential uses of nanomaterials, and therefore exposures, increase exponentially so does the need for thorough evaluation. Up to this point, the majority of research in the field of cardiovascular nanotoxicology has focused on the coronary and vascular reactions to pulmonary exposures in young adult, healthy, male models; however, as intentional and unintentional contacts persist, the non-pulmonary risks to under-represented populations become a critical concern. Development of the maternal-fetal circulation during successful mammalian gestation is one of the most unusual complex, dynamic, and acutely demanding physiological systems. Fetal development in a hostile gestational environment can lead to systemic alterations, which may encourage adult disease. Therefore, the purpose of this review is to highlight the few knowns associated with gestational engineered nanomaterial exposure segmented by physiological periods of development or systemic targets: preconception and maternal, gestational, fetal and progeny (Abstract figure). Overall, the limited studies currently available provide compelling evidence of maternal, fetal and offspring dysfunctions after engineered nanomaterial exposure. Understanding the mechanisms associated with these multigenerational effects may allow pregnant women to safely reap the benefits of nanotechnology-enabled products and assist in the implementation of exposure controls to protect the mother and fetus allowing for development of safety by design for engineered nanomaterials. © 2015 The Authors.

  7. [Impact of pregnancy on pituitary disorders].

    Science.gov (United States)

    Marek, J

    2013-06-01

    In pregnancy, the volume of pituitary increases by multiplication of lactotopic and gonadotropic cells and developing placenta is the source of numerous hormones and enzymes that significantly affect and alter the function of the endocrine system. This naturally has an impact on the course of pituitary disorders and their treatment. The most common disorders of pituitary gland, which we can meet in pregnancy, are adenomas, particularly prolactinomas, and functionless adenomas. During pregnancy we avoid the treatment of microprolactinomas, but in macroprolactinomas where there is the risk of their enlargement by stimulation of placental estrogens, we administer preventively the dopaminergic agonists. Patients with acromegaly usually do not need the treatment during pregnancy, unless there is a danger to damage the visual pathway or heavy headaches occur. ACTH secreting adenomas (Cushings disease) in pregnancy are rare, they are difficult to diagnose but existing hypercortisolism is very dangerous to fetus and may damage even mother. Large functionless adenomas, unless treated before pregnancy, may damage the visual pathway. The volume of the enlarged pituitary gland in pregnancy and sometimes even of the functionless adenoma adenoma, may be reduced by cabergoline, so that the urgent neurosurgery in pregnancy is very rare. A typical disease that occurs primarily in pregnant women is autoimmune lymphocytic hypophysitis. Diagnosis is established on the basis of headaches and symptoms and signs of the deficits of adrenocorticotropic and thyreotropic function usually in the last third of pregnancy or in the first six months after birth, using a specific image in magnetic resonance. Treatment is limited to hormone replacement. It is also possible to meet pregnant women with deficient pituitary functions. In hypocortical women with exception of strains like as pregnancy vomiting, doses of hydrocortisone replacement usually do not change until birth. Childbirth, however

  8. Hypertension in pregnancy.

    Hypertensive disorders of pregnancy represent the second commonest cause of direct maternal death and complicate an estimated 5-10 % of pregnancies. Classification systems aim to separate hypertension similar to that seen outside pregnancy (chronic and gestational hypertension) from the potentially fatal pregnancy-specific conditions. Preeclampsia, HELLP syndrome, and eclampsia represent increasing severities of this disease spectrum. The American College of Obstetricians and Gynecologists' 2013 guidelines no longer require proteinuria as a diagnostic criterion, because of its variable appearance in the disease spectrum. The cause involves inadequate cytotrophoblastic invasion of the myometrium, resulting in placental hypoperfusion and diffuse maternal endothelial dysfunction. Changes in angiogenic and antiangiogentic peptide profiles precede the onset of clinical preeclampsia. Women with preeclampsia should be closely monitored and receive magnesium sulfate intravenously if severe features, HELLP syndrome, or eclampsia occur. Definitive therapy is delivery of the fetus. Hypertension in pregnancy increases future maternal risk of hypertension and cardiovascular disorders.

    Fipronil, a phenylpyrazole insecticide, is used in agriculture, veterinary medicine, and public health. Because this insecticide is considered a potential endocrine disruptor, the aim of this study was to examine the influence of perinatal exposure to fipronil on neonatal female reproductive system development. Pregnant rats were exposed (via gavage) daily to fipronil (0.03, 0.3, or 3 mg/kg) from gestational day 15 to day 7 after birth, and effects on the reproductive functions assessed on postnatal day (PND) 22. No signs of maternal toxicity were observed during daily treatment with fipronil. Perinatal exposure to the highest dose of fipronil (3 mg/kg) delayed the age of vaginal opening (VO) and first estrus without markedly affecting the anogenital distance (AGD). Further, exposure to 0.3 mg/kg fipronil produced a significantly shorter estrus cycle and reduced number of cycles during the period of evaluation. However, the other reproductive parameters analyzed, including fertility, hormone levels, sexual behavior, and histology of ovaries and uterus, displayed no marked alterations. In this experimental model, fipronil interfered with development of neonatal female reproductive system as evidenced by delay in VO and estrus cycle alterations without apparent significant effects on fertility. Further studies are needed to identify the mechanisms of action associated with the observed female reproductive system changes.

    Systemic lupus erythematosus (SLE) and pregnancy-induced hypertension (PIH) are related to premature delivery and intrauterine growth restriction (IUGR), and share histological findings of the placenta. Association with complement dysregulation has been reported in pregnancy for both disorders. The purpose of this study was to investigate the utility of C4d immunohistochemistry for placentas with SLE- and PIH-associated pregnancy. C4d staining was performed on paraffin-embedded tissue of placentas from 26 patients with SLE, 26 with PIH, and 25 control cases. We used the H-score with a range of 0-300 for the evaluation of C4d immunoreactivity. Placentas of SLE and PIH cases showed a higher H-score than control cases (average, SLE, 38.3 (P < 0.05); PIH, 17.8; control, 1.68), with linear staining on the membrane of syncytiotrophoblast. C4d-high groups comprised 50% (12/26) of SLE and 35% (9/26) of PIH cases, with H-scores ranging 14-270 and 15-170. C4d-high groups were significantly associated with low-placental weights and low birth weight in both SLE and PIH (P < 0.05), and lower gestational age (P < 0.05) in PIH cases. These results suggest that C4d might be utilized as a biomarker evaluating the subsequent risk for IUGR and disease control during the gestation period in these patients.

    To compare the maternal and fetal outcomes between childhood-onset and adult-onset systemic lupus erythematosus (SLE), we reviewed the medical records of SLE pregnant women treated from January 2005 to August 2013. For comparison, patients were allocated to one of the two groups, those pregnant patients with SLE onset before 18 years of age (childhood-onset) and ≥18 years (adult-onset). The patients were evaluated at least once in each trimester and postpartum. Relevant maternal and fetal outcomes were extracted, such as lupus flare, preeclampsia/eclampsia, 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. We studied 186 pregnancies (in 180 women), 58 of them had childhood-onset SLE, and the remaining 128 had adult-onset SLE. The rate of maternal and fetal complications was similar in both groups. Multivariate analysis showed that active SLE before pregnancy, primigravida, renal flare, preeclampsia, lupus flare, anticardiolipin antibodies, and low serum complement were associated with an increased risk of poor maternal and fetal outcomes. The diagnosis of childhood-onset had no impact on maternal-fetal outcome. The maternal and fetal outcome in women with childhood-onset SLE is similar to that reported in women with adult-onset SLE. Pregnancy in women with childhood-onset SLE should not be contraindicated if the disease is well controlled.

    To investigate the effects of salpingectomy and methotrexate treatments on ovarian reserve in ectopic pregnancy. In this prospective study, a total of 131 patients with ectopic pregnancy were divided into 3 groups of methotrexate (MTX) only (Group-1, n: 55), salpingectomy only (Group-2, n: 61), and salpingectomy following MTX (Group-3, n: 15). Pretreatment and post-treatment anti-Müllerian hormone (AMH) levels were evaluated. Significant differences in AMH levels were detected between group 1 and group 2 (2.52±1.28 vs. 1.96±1.66, p=0.043), and group 1 and group 3 (2.52±1.28 vs. 1.77±0.76, p=0.035) at one month postoperative. However, these differences disappeared at the 3rd postoperative month. When AMH levels were compared within the same group, postoperative one month AMH levels were significantly lower than the preoperative AMH levels only in group 3 (p=0.03). However, this difference also disappeared at the 3rd postoperative month. Systemic single-dose methotrexate treatment, unilateral salpingectomy, and salpingectomy following methotrexate administration in ectopic pregnancy were reassuring based on pretreatment and post-treatment AMH levels. Current medical and surgical treatment approaches do not have an obvious negative effect on ovarian reserve. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Kim, Ki Ho; Park, J. J.; Yang, M. S.; Kwon, H. J

    2005-01-01

    This report describes the development of a teleoperated cleanup system for use in a highly radioactive environment of DFDF(DUPIC Fuel Demonstration Facility) at KAERI where direct human access to the in-cell is strictly limited. The teleoperated cleanup system was designed to remotely remove contaminants placed or fixed on the floor surface of the hot-cell by mopping them with wet cloth. This cleanup system consists of a mopping slave, a mopping master and a control console. The mopping slave located at the in-cell comprises a mopping tool with a mopping cloth and a mobile platform, which were constructed in modules to facilitate maintenance. The mopping master that is an input device to control the mopping slave has kinematic dissimilarity with the mopping slave. The control console provides a means of bilateral control flows and communications between the mopping master and the mopping slave. In operation, the human operator from the out-of-cell performs a series of decontamination tasks remotely by manipulating the mopping slave located in-cell via a mopping master, having a sense of real mopping. The environmental and mechanical design considerations, and control systems of the developed teleoperated cleanup system are also described.

    Karlsson, Fredrik; Hedström, Karin

    Systems development methods (or methods) are often applied in tailored version to fit the actual situation. Method tailoring is in most the existing literature viewed as either (a) a highly rational process with the method engineer as the driver where the project members are passive information providers or (b) an unstructured process where the systems developer makes individual choices, a selection process without any driver. The purpose of this chapter is to illustrate that important design decisions during method tailoring are made by project members through negotiation. The study has been carried out using the perspective of actor-network theory. Our narratives depict method tailoring as more complex than (a) and (b) show the driver role rotates between the project members, and design decisions are based on influences from several project members. However, these design decisions are not consensus decisions.

    Dysregulation of the immune system plays a role in the pathogenesis of both, pregnancy-induced hypertension (PIH) and systemic lupus erythematosus (SLE). It is well known that SLE predisposes to be complicated with PIH. However, few studies have attempted to investigate whether PIH increased subsequent SLE risk.The objectives of this study were to assess the association between PIH and subsequent SLE risk and identify predictive risk factors.Patients with newly diagnosed PIH were selected from the Taiwan National Health Insurance Research Database (NHIRD) and compared with a matched cohort without PIH based on age and the year of delivery. The incidence of new-onset SLE was evaluated in both cohorts. The overall observational period was from January 1, 2000 to December 31, 2013.Among the 23.3 million individuals registered in the NHIRD, 29,091 patients with PIH and 116,364 matched controls were identified. The incidence of SLE was higher among patients with PIH than in the matched controls (incidence rate ratio [IRR] = 4.02, 95% confidence interval [CI] 3.98-4.05, P < 0.0001). The IRR for subsequent SLE development remained significantly higher in all stratifications during the follow-up years. The multivariate Cox regression model was performed and the results showed that PIH may be an independent risk factors for the development of subsequent SLE (hazard ratio [HR] = 2.87, 95% CI 2.07-3.98, P < 0.0001). Moreover, multivariate Cox regression model was used again among the PIH cohort only in order to identify the possible risk factors for subsequent SLE in the population with PIH.Patients with PIH may have higher risk of developing newly diagnosed SLE than those without PIH. In addition, among individuals who have experienced PIH, those younger than 30 years, having experienced preeclampsia/eclampsia, single parity, preterm birth, or chronic kidney disease, may display an increased subsequent risk of SLE.

    -Army (Global Combat Support System-Army Field/Tactical, is intended for the tactical level and it will replace 14 tactical logistics information systems and connect them with the rest of the information environment. Tendencies in the development of logistics information systems In line with the presented information solutions, it is possible to extract relevant conclusions about tendencies in the development of these types of systems all around the world. These conclusions should be implemented, through adequate principles, into domestic software development. Three main tendencies are visible in modern solutions: using centralised databases, integration of existing separated software solutions, and connecting previously autonomus systems. Conclusion In accordance with present time requirements, logistic support should be realised as close as possible to the origin of a logistic need, in real time and adequately. Information systems enable real time delivery of information needed for a quality logistic support in all phases of operations as well as for a faster generation of all types of documents.

  8. Consumption of fish, butter and margarine during pregnancy and development of allergic sensitizations in the offspring: role of maternal atopy.

    It has been suggested that changes in dietary habits, particularly increased consumption of omega-6 polyunsaturated fatty acids (PUFA) and decreased consumption of omega-3 PUFAs may explain the increase in atopic disease seen in recent years. Furthermore, it seems possible that it is mainly prenatal or very early life environmental factors that influence the development of allergic diseases. It has also been suggested that intrauterine risk factors may act differently if mother themselves suffer from allergic disease. The aim of this study was to investigate whether the consumption of fish, butter and margarine during pregnancy might influence the development of allergic sensitizations in the offspring. The study population was divided into the offspring of allergic and non-allergic mothers. This was a retrospective cohort study enrolling 295 offspring of allergic mothers and 693 of non-allergic mothers. Information regarding maternal intake of fish, butter and margarine during pregnancy as well as other prenatal and perinatal confounding factors were retrospectively assessed by parental report via a standardized questionnaire. Atopy was determined by skin-prick tests (SPT) to eight prevalent inhalant allergens and two foods. In the allergic mothers' group there is no clear correlation between maternal intakes of fish, butter and margarine and sensitizations to food or inhalants. In the non-allergic mothers' group there was no correlation between butter and margarine intake and food or inhalant sensitizations. On the contrary, a protective effect of fish intake on SPT positivity was observed. In particular, frequent maternal intake ('2-3 times/wk or more') of fish reduced the risk of food sensitizations by over a third (aOR 0.23; 95% CI: 0.08-0.69). A similar trend, even if not significant, was found for inhalants. Finally, even in the whole study population, i.e. allergic group plus non-allergic group, there was a similar trend between increased consumption of

  9. Reciprocating Feed System Development Status

    2005-01-01

    The reciprocating feed system (RFS) is an alternative means of providing high pressure propellant flow at low cost and system mass, with high fail-operational reliability. The RFS functions by storing the liquid propellants in large, low-pressure tanks and then expelling each propellant through two or three small, high-pressure tanks. Each RFS tank is sequentially filled, pressurized, expelled, vented, and refilled so as to provide a constant, or variable, mass flow rate to the engine. This type of system is much lighter than a conventional pressure fed system in part due to the greatly reduced amount of inert tank weight. The delivered payload for an RFS is superior to that of conventional pressure fed systems for conditions of high total impulse and it is competitive with turbopump systems, up to approximately 2000 psi. An advanced version of the RFS uses autogenous pressurization and thrust augmentation to achieve higher performance. In this version, the pressurization gases are combusted in a small engine, thus making the pressurization system, in effect, part of the propulsion system. The RFS appears to be much less expensive than a turbopump system, due to reduced research and development cost and hardware cost, since it is basically composed of small high- pressure tanks, a pressurization system, and control valves. A major benefit is the high reliability fail-operational mode; in the event of a failure in one of the three tank-systems, it can operate on the two remaining tanks. Other benefits include variable pressure and flow rates, ease of engine restart in micro-gravity, and enhanced propellant acquisition and control under adverse acceleration conditions. We present a system mass analysis tool that accepts user inputs for various design and mission parameters and calculates such output values payload and vehicle weights for the conventional pressure fed system, the RFS, the Autogenous Pressurization Thrust Augmentation (APTA) RFS, and turbopump systems

  10. Possible roles for folic acid in the regulation of trophoblast invasion and placental development in normal early human pregnancy.

    In addition to its role in the prevention of neural tube defects, folic acid has many other physiological functions, including cell proliferation, DNA replication, and antioxidant protection. The aim of this study was to determine the role that folic acid has in regulating placental trophoblast development. Placental explants from placentae at gestational age 7 wk (n = 3) were cultured in folic acid at concentrations of 10(-6) M, 10(-8) M, and 10(-10) M. Extravillous trophoblast (EVT) invasion was assessed following 6-day culture, and explants were used for immunohistochemical evaluation of proliferation (MKI67) and apoptosis (active caspase 3). In addition, an array was performed on cell culture supernatants to examine a range of matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs). Folic acid increased the invasion of EVT cells in this explant model by between 83% and 19% (P = 0.005), and this was associated with increased MKI67 positivity and decreased active caspase 3 positivity; this effect was concentration dependent and showed a biphasic response. In addition, culture in folic acid increased vascular density, as determined by anti-CD31 immunostaining (P = 0.05). The increase in EVT invasion correlated with increased placental explant secretion of MMP2 (P = 0.01), MMP3 (P = 0.01), and MMP9 (P = 0.02). This study demonstrates that folic acid is potentially important in a number of crucial early stages of placental development, including EVT invasion, angiogenesis, and secretion of MMPs, and highlights the need for further studies to address the benefit of longer-term folic acid supplementation throughout pregnancy to prevent pregnancy disorders associated with deficient placental development, including preeclampsia.

    Results: In our case series two patients required Caesarean section for fetal indication and both the babies had congenital heart block and were asked regular follow up in cardiology outpatient department, two patients required medical termination of pregnancy in view of teratogenic drug exposure(cyclophosphamide, one patient had intrauterine growth restriction and had a preterm vaginal delivery with good fetal outcome and no heart block in the baby and the last patient was diagnosed as a case of SLE when baby was found to have heart block in the antenatal period and was later evaluated and diagnosed as a case of SLE. Conclusions: Lupus activity is increased in pregnancy and patients with SLE are at higher risk for spontaneous abortions, fetal death, PIH, preterm delivery and intrauterine growth retardation. Management of these cases requires a multidisciplinary approach involving the obstetrician, rheumatologist, nephrologist and neonatologist.

    A 31-year-old 2 G 1 P was referred to our unit of prenatal medicine at 35+3 weeks of gestation with a spontaneously conceived singleton pregnancy of a female fetus without detectable anomalies. Maternal hematological evaluation revealed an Evans-syndrome-related thrombocytopenia based on a lupus erythematosus. The former delivery was aggravated by a severe hemorrhage several years before. Anti-autoimmunologic therapy was started and maternal platelets count increased to physiological values. Uneventful ceasarean section was performed at 37 weeks of gestation with favourable outcome for mother and child. This case is the first report of a successful therapy in maternal Evans syndrome in pregnancy combined with a lupus erythematosus.

    Following the UK Medical Research Council\\'s (MRC) guidelines for the development and evaluation of complex interventions, this study aimed to design, develop and optimise an educational intervention about young men and unintended teenage pregnancy based around an interactive film. The process involved identification of the relevant evidence base, development of a theoretical understanding of the phenomenon of unintended teenage pregnancy in relation to young men, and exploratory mixed methods research. The result was an evidence-based, theory-informed, user-endorsed intervention designed to meet the much neglected pregnancy education needs of teenage men and intended to increase both boys\\' and girls\\' intentions to avoid an unplanned pregnancy during adolescence. In prioritising the development phase, this paper addresses a gap in the literature on the processes of research-informed intervention design. It illustrates the application of the MRC guidelines in practice while offering a critique and additional guidance to programme developers on the MRC prescribed processes of developing interventions. Key lessons learned were: (1) know and engage the target population and engage gatekeepers in addressing contextual complexities; (2) know the targeted behaviours and model a process of change; and (3) look beyond development to evaluation and implementation.

    Nutrition at optimal levels is fundamental in the maintenance of positive health. Matemal nutrition is very important for the course and outcome of pregnancy. Lactation represents a stage wherein health and nutritional status of the infant are dependent on the mother. Successful pregnancy and lactation require adjustments in maternal body composition, metabolism and function of various physioogical systems. A diet that meets matemal nutritional needs is required for these adjustments, so that maternal well-being is safeguarded with birth of an healthy infant. Adequate nutrition supports the growth of both matemal and foetal tissues. Chronic undernutrition throughout pregnancy affects birth weights of newborns. Poor nutrition causes intra-uterine growth retardation. Specific nutrients like zinc, iodine and folate are also required for development of the foetus. Foetal iron deficiency exists in maternal iron deficiency anaemia. Maternal nutritional status, breast milk composition and volume are elaborated in the article. Proteins, fats, minerals and vitamins and their requirements are narrated in detail. Additional nutritional requirements during lactation have been tabulated in this article. Thus improving the nutrition and health of girls and younger women and of mothers during pregnancy and lactation will derive benefits in terms of improved health of their children throughout their lives.

  16. A Spotty Liver of Pregnancy

    Full Text Available Herpes simplex virus (HSV hepatitis by definition constitutes disseminated herpes simplex infection; it is rare, with only approximately 130 cases reported in the literature. Although HSV hepatitis typically occurs in immunocompromised hosts, pregnancy—especially the third trimester, has been identified as a risk factor for its development. This is likely because of the fact that humoral and cell-mediated immunity decrease throughout pregnancy and nadir in the third trimester with decreased T-cell counts and altered B/T lymphocyte ratios. Here, we report on a patient with HSV 2 hepatitis in a previously healthy 27-year-old woman in her 23rd week of pregnancy. She initially presented with nausea, vomiting, and abdominal pain and was found to have acute hepatocellular liver injury and a systemic inflammatory response syndrome. Broad-spectrum antibiotics and acyclovir were promptly initiated. Liver biopsy, serum DNA polymerase chain reaction (PCR as well as a labial ulcer culture and PCR were all positive for HSV 2. The patient recovered completely; however, her fetus did not survive. Review of the literature emphasizes that presentation with disseminated HSV infection typically occurs in the third trimester of pregnancy. This report emphasizes that abdominal pain combined with fever and hepatic dysfunction in pregnancy should prompt immediate consideration of the diagnosis of HSV hepatitis. Furthermore, given the high mortality rate and effective treatment, empiric treatment with acyclovir should be considered early in all potential cases.

    The treatment of inflammatory rheumatic diseases, such as rheumatoid arthritis, spondylitis ankylosans and systemic lupus erythematosus, is improving continuously. This has lead to an increasing number of young patients with a wish to have children. Greater insight into the course of rheumatic diseases during pregnancy and post partum has enabled optimized support for women with rheumatic diseases wishing to have children. To ensure a favorable outcome, pregnancy should be started during a period of disease stability and should be monitored closely. A careful assessment of possible risks and the justified use of antirheumatic drugs before, during and after pregnancy are key issues for success.

    Diagnosis of urolithiasis during pregnancy is a common condition not more frequent than in non pregnant women. Ultrasonography will be the main tool of diagnosis. If sonography fails, ionizing radiation will be used only if MRI is not available. One must take care of the mother and the foetus because preterm delivery is increased in case of lithiasis during pregnancy. Conservative treatment is favoured taking care of specific contraindications of medical therapy related to pregnancy. In case of complications, drainage of the urinary system by retrograde or antegrade approach will be considered. Endoscopic treatment is realized only in case of failure of drainage or in the post-partum with etiologic investigations.

    This work assessed the temporal coexpression of interleukin 1 (IL-1) and its inhibitor, IL-1 receptor antagonist (IL-1ra), in the cervicovaginal fluid (CVF) beyond 24 weeks gestation including women in spontaneous term labor. Two cohorts of women were recruited at 24 to 35 weeks' gestation (n = 65) and in late pregnancy (>36 weeks' gestation; n = 88). The CVF was serially collected either every 4 weeks between 24 and 35 weeks' gestation (n = 123 samples) or weekly during late pregnancy (n = 240 samples). The IL-1 and IL-1ra were quantitated by enzyme-linked immunosorbent assay, and the effect of vaginal microflora and unprotected sexual intercourse were also investigated. The IL-1β and IL-1ra remain unaltered between 24 and 35 weeks' gestation. At late pregnancy, IL-1α and β concentrations peak at 4 to 14 days prior to labor onset, while IL-1ra decreases with approaching spontaneous term labor (P labor with 86% sensitivity and 92% specificity. This study indicates a shifting inflammatory balance in the gestational tissues prior to labor onset.

    Full Text Available Community-based early warning systems (CBEWS is a “people-centered” system and empowers individuals and communities threatened by hazards to act on sufficient time and in an appropriate manner to reduce the possibility of personal injury, loss of life, damage to property, environment and loss of livelihood. These things lead to the development of the device necessary for the protection of the community against flood hazards as it allows people to get prepared with sufficient time. An alarm system was developed to monitor the water level on Salog River that overflows during heavy rains. The water level sensors were submerged in a canal of water to test the functionality of the device before its installation. Computer programs were created to enhance the monitoring of water level: the River Monitor Software and the Water Level Monitor. The LED arrays emit light according to water level; green for low, orange for medium, and red for high. A siren also alarms with different intervals (30 seconds for low, 15 seconds for medium, and a continuous alarm for high. Automatic emergency lighting was integrated in the design and lights up during power outages powered by rechargeable sealed battery that charges when ac power is supplied to the device. Levels were established based on available data; low water level means awareness; medium water level means preparedness and high water level means immediate response is necessary.

    Design, high-voltage test, and installation of 6 MW ICRF heating system for KSTAR is completed. The antenna demonstrated satisfactory standoff at high voltages up to 41 kV for 300 sec. The result indicates good power handling capabilities of the antenna as high as 10 MW/m2. This power density is equivalent to RF power coupling of 6 MW into a 4 {omega}/m target plasma, and is typical of advanced tokamak heating scenarios. In addition, vacuum feed through, DC break, and liquid stub developed for 300 sec operation are installed, as well as a 2 MW, 30-60MHz transmitter. The transmitter successfully produced output powers of 600 kW continuously, 1.5{approx}1.8 MW for 300 sec, and 2 MW for 100 msec or shorter pulses. A realtime control system based on DSP and EPICS is developed, installed, and tested on the ICRF system. Initial results from feasibility study indicate that the present antenna and the transmission lines could allow load-resilient operation on KSTAR. Until the KSTAR tokamak start to produce plasmas in 2008, however, hands-on operational experiences are obtained from participating in ICRF heating experiments at ASDEX and DIII-D tokamaks arranged through international cooperation.

    Recently, an increased incidence of central diabetes insipidus (CDI) in pregnancy, and less frequently in the post partum period, has been reported, most probably favoured by some conditions occurring in pregnancy. This study was aimed at investigating the influence of pregnancy on a pre-existing potential/subclinical hypothalamic autoimmunity. We studied the longitudinal behaviour of arginine-vasopressin cell antibodies (AVPcAbs) and post-pituitary function in two young women with a positive history of autoimmune disease and presence of AVPcAbs, but without clinical CDI, and who became pregnant 5 and 7 months after our first observation. The behaviour of post-pituitary function and AVPcAbs (by immunofluorescence) was evaluated at baseline, during pregnancy and for 2 years after delivery. AVPcAbs, present at low/middle titres at baseline in both patients, showed a titre increase during pregnancy in one patient and after delivery in the other patient, with development of clinically overt CDI. Therapy with 1-deamino-8-d-arginine vasopressin (DDAVP) caused a prompt clinical remission. After a first unsuccessful attempt of withdrawal, the therapy was definitively stopped at the 6th and the 7th month of post partum period respectively, when AVPcAbs disappeared, accompanied by post-pituitary function recovery, persisting until the end of the follow-up. The determination of AVPcAbs is advisable in patients with autoimmune diseases planning their pregnancy, because they could be considered good predictive markers of gestational or post partum autoimmune CDI. The monitoring of AVPcAb titres and post-pituitary function during pregnancy in these patients may allow for an early diagnosis and an early replacement therapy, which could induce the disappearance of these antibodies with consequent complete remission of CDI.

    2016-01-01

    Renal failure during pregnancy affects both mother and fetus, and may be related to preexisting disease or develop secondary to diseases of pregnancy. Causes include hypovolemia, sepsis, shock, preeclampsia, thrombotic microangiopathies, and renal obstruction. Treatment focuses on supportive measures, while pharmacologic treatment is viewed as second-line therapy, and is more useful in mitigating harmful effects than treating the underlying cause. When supportive measures and pharmacotherapy prove inadequate, dialysis may be required, with the goal being to prolong pregnancy until delivery is feasible. Outcomes and recommendations depend primarily on the underlying cause.

    The Compact Microscope Imaging System (CMIS) is a diagnostic tool with intelligent controls for use in space, industrial, medical, and security applications. The CMIS can be used in situ with a minimum amount of user intervention. This system, which was developed at the NASA Glenn Research Center, can scan, find areas of interest, focus, and acquire images automatically. Large numbers of multiple cell experiments require microscopy for in situ observations; this is only feasible with compact microscope systems. CMIS is a miniature machine vision system that combines intelligent image processing with remote control capabilities. The software also has a user-friendly interface that can be used independently of the hardware for post-experiment analysis. CMIS has potential commercial uses in the automated online inspection of precision parts, medical imaging, security industry (examination of currency in automated teller machines and fingerprint identification in secure entry locks), environmental industry (automated examination of soil/water samples), biomedical field (automated blood/cell analysis), and microscopy community. CMIS will improve research in several ways: It will expand the capabilities of MSD experiments utilizing microscope technology. It may be used in lunar and Martian experiments (Rover Robot). Because of its reduced size, it will enable experiments that were not feasible previously. It may be incorporated into existing shuttle orbiter and space station experiments, including glove-box-sized experiments as well as ground-based experiments.

  7. Impact of maternal metabolic abnormalities in pregnancy on human milk and subsequent infant metabolic development: methodology and design

    2010-10-01

    Full Text Available Abstract Background Childhood obesity is on the rise and is a major risk factor for type 2 diabetes later in life. Recent evidence indicates that abnormalities that increase risk for diabetes may be initiated early in infancy. Since the offspring of women with diabetes have an increased long-term risk for obesity and type 2 diabetes, the impact of maternal metabolic abnormalities on early nutrition and infant metabolic trajectories is of considerable interest. Human breast milk, the preferred food during infancy, contains not only nutrients but also an array of bioactive substances including metabolic hormones. Nonetheless, only a few studies have reported concentrations of metabolic hormones in human milk specifically from women with metabolic abnormalities. We aim to investigate the impact of maternal metabolic abnormalities in pregnancy on human milk hormones and subsequently on infant development over the first year of life. The objective of this report is to present the methodology and design of this study. Methods/Design The current investigation is a prospective study conducted within ongoing cohort studies of women and their offspring. Pregnant women attending outpatient obstetrics clinics in Toronto, Canada were recruited. Between April 2009 and July 2010, a total of 216 pregnant women underwent a baseline oral glucose tolerance test and provided medical and lifestyle history. Follow-up visits and telephone interviews are conducted and expected to be completed in October 2011. Upon delivery, infant birth anthropometry measurements and human breast milk samples are collected. At 3 and 12 months postpartum, mothers and infants are invited for follow-up assessments. Interim telephone interviews are conducted during the first year of offspring life to characterize infant feeding and supplementation behaviors. Discussion An improved understanding of the link between maternal metabolic abnormalities in pregnancy and early infant nutrition may

    2001-01-01

    Many industrial and commercial products operate in a dynamic flow environment and the aerodynamically generated noise has become a very important factor in the design of these products. In light of the importance in characterizing this dynamic environment, Rocketdyne has initiated a multiyear effort to develop an advanced general-purpose Computational Aeroacoustic Analysis System (CAAS) to address these issues. This system will provide a high fidelity predictive capability for aeroacoustic design and analysis. The numerical platform is able to provide high temporal and spatial accuracy that is required for aeroacoustic calculations through the development of a high order spectral element numerical algorithm. The analysis system is integrated with well-established CAE tools, such as a graphical user interface (GUI) through PATRAN, to provide cost-effective access to all of the necessary tools. These include preprocessing (geometry import, grid generation and boundary condition specification), code set up (problem specification, user parameter definition, etc.), and postprocessing. The purpose of the present paper is to assess the feasibility of such a system and to demonstrate the efficiency and accuracy of the numerical algorithm through numerical examples. Computations of vortex shedding noise were carried out in the context of a two-dimensional low Mach number turbulent flow past a square cylinder. The computational aeroacoustic approach that is used in CAAS relies on coupling a base flow solver to the acoustic solver throughout a computational cycle. The unsteady fluid motion, which is responsible for both the generation and propagation of acoustic waves, is calculated using a high order flow solver. The results of the flow field are then passed to the acoustic solver through an interpolator to map the field values into the acoustic grid. The acoustic field, which is governed by the linearized Euler equations, is then calculated using the flow results computed

    Pregnancy with uterine prolapse is a relatively rare condition. Irreducible prolapse occurring during pregnancy is even rarer. There is still a need for obstetricians to be aware about the management of uterine prolapse which allows for an uneventful pregnancy, labour and delivery. Here we present a case of a woman who developed irreducible uterine prolapse during pregnancy and the issues surrounding its management. We had to abort her pregnancy to reduce her prolapse which could otherwise have been life threatening.

    Full Text Available Abstract Background The rate of caesarean sections is increasing worldwide, yet medical literature informing women with uncomplicated pregnancies about relative risks and benefits of elective caesarean section (CS compared with vaginal delivery (VD remains scarce. A decision board may address this gap, providing systematic evidence-based information so that patients can more fully understand their treatment options. The objective of our study was to design and pre-test a decision board to guide clinical discussions and enhance informed decision-making related to delivery approach (CS or VD in uncomplicated pregnancy. Methods Development of the decision board involved two preliminary studies to determine women's preferred mode of risk presentation and a systematic literature review for the most comprehensive presentation of medical risks at the time (VD and CS. Forty women were recruited to pre-test the tool. Eligible subjects were of childbearing age (18-40 years but were not pregnant in order to avoid raising the expectation among pregnant women that CS was a universally available birth option. Women selected their preferred delivery approach and completed the Decisional Conflict Scale to measure decisional uncertainty before and after reviewing the decision board. They also answered open-ended questions reflecting what they had learned, whether or not the information had helped them to choose between birth methods, and additional information that should be included. Descriptive statistics were used to analyse sample characteristics and women's choice of delivery approach pre/post decision board. Change in decisional conflict was measured using Wilcoxon's sign rank test for each of the three subscales. Results The majority of women reported that they had learned something new (n = 37, 92% and that the tool had helped them make a hypothetical choice between delivery approaches (n = 34, 85%.

    The UK government argues that "social exclusion" increases risk of teenage pregnancy and that educational factors may be dimensions of such exclusion. The evidence cited by the government is limited to reporting that socioeconomic disadvantage and educational attainment influence risk. Evidence regarding young people's attitude to school is not cited, and there is a lack of research concerning the UK. This paper develops hypotheses on the relation between socioeconomic and educational dimensions of social exclusion, and risk of teenage pregnancy, by examining whether dislike of school and socioeconomic disadvantage are associated with cognitive/behavioural risk measures among 13/14 year olds in English schools. Analysis of data from the baseline survey of a study of sex education. 13/14 year old school students from south east England. The results indicate that socioeconomic disadvantage and dislike of school are associated with various risk factors, each with a different pattern. Those disliking school, despite having comparable knowledge to those liking school, were more likely to have sexual intercourse, expect sexual intercourse by age 16, and expect to be parents by the age of 20. For most associations, the crude odds ratios (ORs) and the ORs adjusted for the other exposure were similar, suggesting that inter-confounding between exposures was limited. It is hypothesised that in determining risk of teenage pregnancy, the two exposures are independent. Those disliking school might be at greater risk of teenage pregnancy because they are more likely to see teenage pregnancy as inevitable or positive.

  17. Maternal nutrition among women from Sub-Saharan Africa, with a focus on Nigeria, and potential implications for pregnancy outcomes among immigrant populations in developed countries.

    2012-12-01

    Pregnant women in countries of Sub-Saharan Africa (SSA) are at risk of poor nutritional status and adverse outcomes as a result of poverty, food insecurity, sub-optimal healthcare facilities, frequent infections and frequent pregnancies. Studies from Nigeria, for example, have revealed a high prevalence of both under- and over-nutrition, as well as nutrient deficiencies, including iron, folate, vitamin D and vitamin A. Subsequently, obstetric complications, including hypertension, anaemia, neural tube defects, night-blindness, low birth weight and maternal and perinatal mortality, are common. Migration patterns from SSA to the Western world are on the rise in recent years, with Nigerians now representing the most prevalent immigrant African population in many developed countries. However, the effect of immigration, if any, on the nutritional status and pregnancy outcomes of these women in their host countries has not yet been studied. Consequently, it is unknown to what extent the nutritional deficiencies and pregnancy complications occurring in Nigeria, and other countries of SSA, present in these women post-emigration. This may result in missed opportunities for appropriate antenatal care of a potential high-risk group in pregnancy. The present review discusses the literature regarding nutrition in pregnancy among SSA women, using Nigeria as an example, the common nutrition-related complications that arise and the subsequent obstetric outcomes. The concept of dietary acculturation among immigrant groups is also discussed and deficiencies in the literature regarding studies on the diets of pregnant immigrant women are highlighted.

  18. Pregnancy: an immune challenge

    Directory of Open Access Journals (Sweden)

    Maria Angelica Ehara Watanabe

    2014-12-01

    Full Text Available Several studies demonstrate the importance of immunological aspects of pregnancy. During pregnancy, the embryo is implanted in the womb, where it will develop until the end of pregnancy. Amongst the immune aspects, the importance of the modulation of T lymphocytes, natural killers (NK cells and many cytokines in maternal organism can be mentioned. The maternal tolerance to the fetus appears to be mediated by specific maternal hormones and by the expression of human leukocyte antigen G (HLA-G - characteristic in pregnancy. Other studies suggest that fetal rejection and complications during pregnancy may occur because of the presence of minor histocompatibility antigens (mHAg, acquired by blood sharing of the mother with the fetus, and because of the presence of maternal antibodies against the sperm and against the fetus. The purpose of this review is to describe the immunological aspects that allow maternal tolerance to the fetus during pregnancy, as well as possible causes for rejection of the embryo and complications during pregnancy.

    2012-10-01

    Successful outcome in pregnancy hyperthyroidism depends on the cause, interpretation of laboratory tests, and careful use of antithyroid drug (ATD) therapy. Planning of a pregnancy in a woman with active or past history of Graves' hyperthyroidism is mandatory in order to avoid complications. Fetal health may be affected by three factors: poor control of maternal hyperthyroidism, titer of maternal TRAb, and inappropriate use of ATD. Careful assessment of thyroid function through pregnancy and evaluation of fetal development by ultrasonography is the cornerstone for a successful outcome. In a subgroup of women previously treated with ablation therapy, those whose serum TSRAb titers remained elevated, are at risk of having a fetus/neonate with Graves' hyperthyroidism. Use of ATD during lactation is well tolerated, if recommended guidelines are followed. Women during their childbearing age with active Graves' hyperthyroidism should plan their pregnancy. Causes of hyperthyroidism in pregnancy include Graves' disease or autonomous adenoma, and transient gestational thyrotoxicosis as a consequence of excessive production of human chroionic gonadotropin by the placenta. Careful interpretation of thyroid function tests and frequent adjustment of ATD is of utmost importance in the outcome of pregnancy. Graves' hyperthyroidism may relapse early in pregnancy or at the end of the first year postpartum.

  20. [Adolescent pregnancy].

    The number of adolescent pregnancies brought to term in France has continued to decline while the number of abortions remains stable. Adolescent pregnancies cannot be considered "accidents" either in their social or psychological aspects. Pregnant adolescents carrying to term tend to be more disadvantaged than those seeking abortions. Early pregnancy may be a response to difficult life conditions. Despite appearing to constitute an infraction of a social code, adolescent pregnancy may in fact represent an attempt at social integration through motherhood. Adolescents failing in school, with poor employment prospects and feeling family pressures may view pregnancy as a means of social recognition. But such factors by themselves do not explain pregnancy; the primordial role of psychological factors must be examined. For some adolescents, pregnancy may represent an attempt to understand their own sexual identity as the transformations of puberty unsettle their previous self-images. Or they may be failing to perceive or actively denying the possibility of pregnancy. Adolescent pregnancies may be the result of transgressions of prohibitions. The traditional prohibition of sexual activity has relaxed to the degree that it is being replaced by a new prohibition on adolescent pregnancy and a prescription to use contraception. But contraception deprives an adolescent in search of sexual identity of proof of fertility as well as of the image of spontaneity and naturalness. Use of contraception is in conflict with the questions, doubts, and anxieties of adolescence. For adolescents in a reactivated oedipal stage, heterosexuality is often at the service of incestuous fantasies involving the mother. Abortion and perhaps pregnancy itself may assume the character of a rite of passage into adulthood for some adolescents. The important thing for many is the ability to become pregnant, to be a mother like their own mother.

    Establishment of pregnancy in the pig depends on down-regulation of progesterone receptor (PGR) in the uterine luminal and glandular epithelium during the first week after breeding. The present study evaluated the regulation of endometrial PGR by progesterone and the possible role of endometrial tumor necrosis factor (ligand) superfamily member 11 (TNFSF11) and nuclear factor-kappa B (NFKB) activation in PGR expression. Mature, cycling gilts were inseminated (Day 0) and assigned to either untreated control (n = 9) or one of two treatments that employed RU 486 to block progesterone action either before (treatment 1 [T1]) or after (treatment 2 [T2]) the initiation of PGR down-regulation. The T1 gilts were treated with RU 486 (400 mg/day) on Days 3-5 of pregnancy (n = 9), and T2 gilts were treated with RU 486 on Days 6 and 7 of pregnancy (n = 9). Uteri and ovaries were collected on Day 8 or 12 of gestation. The diameter of the conceptuses in T1 gilts was approximately half that in controls by Day 8, and normal conceptuses were not collected from any T1 gilts on Day 12. Endometrial PGR mRNA was more abundant in T1 and T2 gilts compared with control gilts. The PGR-B protein decreased from Day 8 to Day 12 in the luminal epithelium and, to some extent, in superficial glandular epithelium in control and T2 gilts. In T1 gilts, the PGR-B protein remained elevated (i.e., failed to undergo down-regulation) on Day 12. Blocking PGR action early in the cycle (i.e., on or before Day 5), therefore, prevented normal conceptus development, caused elevated PGR mRNA, and prevented the decrease in PGR protein that typically occurs in pigs. We could not confirm a role for NFKB activation in PGR down-regulation, because pigs with extreme differences in PGR and TNFSF11 expression (T1 and controls) had similar NFKB activation on Day 8. Activated NFKB within the luminal epithelium and glandular epithelium (both superficial and deep) was observed in T2 and control pigs on Day 12 when

    The study assesses the experience of pregnancy of women who have pregnancy induced hypertension (PIH) compared to women with an uncomplicated course of pregnancy. 21 women were retrospectively investigated between 5 and 13 months after giving birth via a semistandardised interview focussing on the personal experience of pregnancy. The interviews were analysed by means of qualitative content analysis. The categories "development and course," "coping with anxiety," "image of one's mother" and "relationship with partner" were determined and described. Finally, we developed data-driven, ideal-type models of pregnancies with pregnancy-induced hypertension versus normal pregnancies by detecting the similarities and contrasts between the groups. Interviewees with pregnancy-induced hypertension showed an ambivalence with regard to their pregnancy, which was more often than not unplanned and/or unwanted. Conflicts with significant others, especially with their partners, were also reported more often. Emotions tended to be understated. The results can be employed in the operationalisation of future projects in a hitherto unclear research field. They should also be considered in the care of patients with pregnancy-induced hypertension.

  13. Pregnancy and rheumatic diseases.

    2007-11-01

    Pregnancy is an issue that should be discussed with all patients with rheumatic diseases who are in the reproductive age group. Infertility is rarely due to the disease but can be associated with cyclophosphamide therapy. Most rheumatic diseases that are well controlled prior to pregnancy do not deteriorate in pregnancy, providing that the patient continues with appropriate disease-modifying therapy. Some patients with inflammatory arthritis go in to remission during pregnancy. Patients with renal involvement may be at increased risk of disease flare. This needs to be distinguished from pre-eclampsia. Intrauterine growth restriction is more likely in patients with active systemic disease, hypertension, a history of thrombosis and renal involvement. Premature delivery may need to be planned to reduce the risks of stillbirth and can be associated with a variety of neonatal complications. Post-partum flare is common in all the rheumatic diseases.

  14. PP097. Cardiac output and systemic vascular resistance in normal pregnancy and in control non-pregnant women.

    Changes in cardiac output (CO) and systemic vascular resistance (SVR) have been shown to precede the clinical onset of pregnancy complications, such as pre-eclampsia and fetal growth restriction. CO and SVR undergo major changes during normal pregnancy. However, assessment of these vascular parameters requires intensive training and expensive techniques, so currently can be performed only in specialised centres. The aim of this study was to investigate maternal cardiovascular function measured using an ultrasonic cardiac output monitor (USCOM), a simple non-invasive continuous wave Doppler device, in a cohort of pregnant women and non-pregnant controls. This was a cross sectional study including 185 women with normal singleton pregnancies at 11-40weeks of gestation and 49 non-pregnant controls. Stroke volume (SV), CO and SVR were measured using the USCOM device. All measurements were performed with the patients in supine position. All women with a gestational age of >20weeks were in a left lateral position by placing a wedge-shaped pillow under their right side to prevent vena cava compression. In a group of 25 pregnant women, each measurement was repeated three times to evaluate the reproducibility of this technique. Cardiac index (CI), SV index (SVI) and SVR index (SVRI) relate CO, SV and SVR to the body surface area. The data were normally distributed after logarithmic transformation. Comparisons between pregnant and non-pregnant women were performed using Studentt-test, Chi-Square test or multiple regression analysis, when adjustment for potential confounders was necessary. Data analysis was performed using SPSS 16.0. In the first trimester, all of the following vascular parameters were higher in pregnant women compared to non-pregnant controls: CO [median (IQR): 4.86 (4.45-5.57) vs 5.57 (4.76-6.52)L/min, PPregnant women had significantly lower SVR [median (IQR): 1458 (1261-1649) vs 1165 (1023-1406)sec/cm(-5), P<0.001] and SVRI [median (IQR): 2646 (2307

  15. An analysis of pregnancy-related mortality in the KEMRI/CDC health and demographic surveillance system in western Kenya.

    Full Text Available BACKGROUND: Pregnancy-related (PR deaths are often a result of direct obstetric complications occurring at childbirth. METHODS AND FINDINGS: To estimate the burden of and characterize risk factors for PR mortality, we evaluated deaths that occurred between 2003 and 2008 among women of childbearing age (15 to 49 years using Health and Demographic Surveillance System data in rural western Kenya. WHO ICD definition of PR mortality was used: "the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the cause of death". In addition, symptoms and events at the time of death were examined using the WHO verbal autopsy methodology. Deaths were categorized as either (i directly PR: main cause of death was ascribed as obstetric, or (ii indirectly PR: main cause of death was non-obstetric. Of 3,223 deaths in women 15 to 49 years, 249 (7.7% were PR. One-third (34% of these were due to direct obstetric causes, predominantly postpartum hemorrhage, abortion complications and puerperal sepsis. Two-thirds were indirect; three-quarters were attributable to human immunodeficiency virus (HIV/AIDS, malaria and tuberculosis. Significantly more women who died in lower socio-economic groups sought care from traditional birth attendants (p = 0.034, while less impoverished women were more likely to seek hospital care (p = 0.001. The PR mortality ratio over the six years was 740 (95% CI 651-838 per 100,000 live births, with no evidence of reduction over time (χ(2 linear trend = 1.07; p = 0.3. CONCLUSIONS: These data supplement current scanty information on the relationship between infectious diseases and poor maternal outcomes in Africa. They indicate low uptake of maternal health interventions in women dying during pregnancy and postpartum, suggesting improved access to and increased uptake of skilled obstetric care, as well as preventive measures against HIV/AIDS, malaria and tuberculosis among all women of childbearing age may

    The dendritic cell system contains conventional dendritic cells (DCs) and plasmacytoid pre-dendritic cells (pDCs). Both DCs and pDCs are bone marrow derived calls. Although the common functions of DCs are antigen-processing and T-lymphocyte activation, they differ in surface markers, migratory patterns, and cytokine output. These differences can determine the fate of the T cells they activate. Several subsets of mature DCs have been described in both mouse and human and the developmental processes of these specialized DC subsets have been studied extensively. The original concept that all DCs were of myeloid origin was questioned by several recent studies, which demonstrated that in addition to the DCs derived from myeloid precursors, some DCs could also be efficiently generated from lymphoid-restricted precursors. Moreover, it has been shown recently that both conventional DCs and pDCs can be generated by the Fit3 expressing hemopoietic progenitors regardless of their myeloid- or lymphoid-origin. These findings suggest an early developmental flexibility of precursors for DCs and pDCs. This review summarizes some recent observations on the development of DC system in both human and mouse.

    The prevalence of medical problems in pregnancy is increasing because of a complex interplay between demographic and lifestyle factors, and developments in modern medicine. Maternal mortality and morbidity resulting from treatable medical conditions, such as venous thromboembolism, epilepsy and autoimmune disease, have not decreased in recent years. This is despite a marked decrease in overall maternal mortality. It is vital that all physicians acquire a basic knowledge and understanding of medical problems in pregnancy. This includes prepregnancy measures such as counselling and optimisation of medical therapy, as well as multidisciplinary management throughout pregnancy and the postpartum period. Prompt recognition and treatment of acute and chronic illness is of clear benefit, and most drugs and many radiological investigations may be used in pregnancy.
