The optimal timing of pregnancy after kidney transplantation remains uncertain. We determined the risk of allograft failure among women who became pregnant within the first 3 posttransplant years. Among 21 814 women aged 15-45 years who received a first kidney-only transplant between 1990 and 2010 captured in the United States Renal Data System, n = 729 pregnancies were identified using Medicare claims. The probability of allograft failure from any cause including death (ACGL) at 1, 3, and 5 years after pregnancy was 9.6%, 25.9%, and 36.6%. In multivariate analyses, pregnancy in the first posttransplant year was associated with an increased risk of ACGL (hazard ratio [HR]: 1.18; 95% confidence interval [CI] 1.00, 1.40) and death censored graft loss (DCGL) (HR:1.25; 95% CI 1.04, 1.50), while pregnancy in the second posttransplant year was associated with an increased risk of DCGL (HR: 1.26; 95% CI 1.06, 1.50). Pregnancy in the third posttransplant year was not associated with an increased risk of ACGL or DCGL. These findings demonstrate a higher incidence of allograft failure after pregnancy than previously reported and that the increased risk of allograft failure extends to pregnancies in the second posttransplant year. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

[Early diagnosis of ectopic pregnancy].

Belics, Zoran; Gérecz, Balázs; Csákány, M György

2014-07-20

Ectopic pregnancy is a high-risk condition that occurs in 2% of reported pregnancies. This percentage is fivefold higher than that registered in the 1970s. Since 1970 there has been a two-fold increase in the ratio of ectopic pregnancies to all reported pregnancies in Hungary and in 2012 7.4 ectopic pregnancies per thousand registered pregnancies were reported. Recently, the majority (80%) of cases can be diagnosed in early stage, and the related mortality objectively decreased in the past few decades to 3.8/10,000 ectopic pregnancies. If a woman with positive pregnancy test has abdominal pain and/or vaginal bleeding the physician should perform a work-up to safely exclude the possibility of ectopic pregnancy. The basis of diagnosis is ultrasonography, especially vaginal ultrasound examination and measurement of the β-subunit of human chorionic gonadotropin. The ultrasound diagnosis is based on the visualization of an ectopic mass rather than the inability to visualize an intrauterine pregnancy. In some questionable cases the diagnostic uterine curettage or laparoscopy may be useful. The actuality of this topic is justified by practical difficulties in obtaining correct diagnosis, especially in the early gestational time.

Early pregnancy azathioprine use and pregnancy outcomes.

Cleary, Brian J; Källén, Bengt

Azathioprine (AZA) is used during pregnancy by women with inflammatory bowel disease (IBD), other autoimmune disorders, malignancy, and organ transplantation. Previous studies have demonstrated potential risks. The Swedish Medical Birth Register was used to identify 476 women who reported the use of AZA in early pregnancy. The effect of AZA exposure on pregnancy outcomes was studied after adjustment for maternal characteristics that could act as confounders. The most common indication for AZA use was IBD. The rate of congenital malformations was 6.2% in the AZA group and 4.7% among all infants born (adjusted OR: 1.41, 95% CI: 0.98-2.04). An association between early pregnancy AZA exposure and ventricular/atrial septal defects was found (adjusted OR: 3.18, 95% CI: 1.45-6.04). Exposed infants were also more likely to be preterm, to weigh <2500 gm, and to be small for gestational age compared to all infants born. This effect remained for preterm birth and low birth weight when infants of women with IBD but without AZA exposure were used as a comparison group. A trend toward an increased risk of congenital malformations was found among infants of women with IBD using AZA compared to women with IBD not using AZA (adjusted OR: 1.42, 95% CI: 0.93-2.18). Infants exposed to AZA in early pregnancy may be at a moderately increased risk of congenital malformations, specifically ventricular/atrial septal defects. There is also an increased risk of growth restriction and preterm delivery. These associations may be confounded by the severity of maternal illness.

Anti-early pregnancy by PDT

The effect of laser on anti-early pregnancy in rabbits showed that laser in combination with HPD could induce necrosis of blastocysts and complete absorption. The anti-fertility efficiency of the combined treatment was more effective than that of the He-Ne laser or the HPD treatment alone. The fluorescence spectrum of HPD determined by PNQ3 showed that its affinity to embryonic tissue was about 4 times greater than that to uterine tissue. This may underlie the mechanisms of anti-early pregnancy of the laser. The operation of artificial abortion is a routine method to terminate early pregnancy. Though it is simple and easy, its syndrome and complications can not be absolutely avoided. Many antifertility drugs have been reported, however, they often bring in general reaction. Our present work is to explore a new way of anti-early pregnancy in rabbits by means of the light inhibitory and light sensitive effects of laser. It is a quite safe and painless treatment without expanding and scraping of the uterus.

Background Complications in early pregnancy, such as threatened or actual miscarriage is a common occurrence resulting in many women presenting to the emergency department (ED). Early pregnancy service delivery models described in the literature vary in terms of approach, setting and outcomes. Our objective was to determine outcomes of women who presented to an Australian regional ED with diagnoses consistent with early pregnancy complications following the implementation of an early pregnancy assessment service (EPAS) and early pregnancy assessment protocol (EPAP) in July 2011. Methods A descriptive, comparative (6 months before and after) study was undertaken. Data were extracted from the hospital ED information system and medical healthcare records. Outcome measures included: time to see a clinician, ED length of stay, admission rate, re-presentation rate, hospital admission and types of pathology tests ordered. Results Over the 12 -month period, 584 ED presentations were made to the ED with complications of early pregnancy (268 PRE and 316 POST EPAS–EPAP). Outcomes that improved statistically and clinically following implementation included: time to see a clinician (decreased by 6 min from 35 to 29 min), admission rate (decreased 6% from 14.5% to 8.5%), increase in β-human chorionic gonadotrophin ordering by 10% (up to 80% POST), increase in ultrasound (USS) performed by 10% (up to 73% POST) and increase in pain score documentation by 23% (up to 36% POST). Conclusions The results indicate that patient and service delivery improvements can be achieved following the implementation of targeted service delivery models such as EPAS and EPAP in the ED.

Background. One of the treatment modalities for ectopic pregnancy is methotrexate. The purpose of this study is to identify the failure rate of methotrexate in treating patients with ectopic pregnancy as well as the risk factors leading to treatment failure. Methods. A retrospective chart review of 225 patients who received methotrexate as a primary management option for ectopic pregnancy. Failure of single dose of methotrexate was defined as drop of BHCG level less than or equal to 14% in the seventh day after administration of methotrexate. Results. 225 patients had methotrexate. Most of the patients (151 (67%)) received methotrexate based on the following formula: f 50 mg X body surface area. Single dose of methotrexate was successful in 72% (162/225) of the patients. 28% (63/225) were labeled as failure of single dose of methotrexate because of suboptimal drop in BhCG. 63% (40/63) of failure received a second dose of methotrexate, and 37% (23/63) underwent surgical treatment. Among patient who received initial dose of methotrexate, 71% had moderate or severe pain, and 58% had ectopic mass size of more than 4 cm on ultrasound. Conclusion. Liberal use of medical treatment of ectopic pregnancy results in 71% success rate. PMID:25861275

Early embryonic resorption or fetal loss is known to occur occasionally in captive elephants; however, this has mostly been reported anecdotally. The present study documents the case of a 24-year-old, multiparous Asian elephant cow that suffered embryonic death and resorption at around 18 weeks of gestation. From ovulation onwards, this female was sonographically examined 58 times. Blood was collected twice weekly for progestagen determination via enzyme immunoassay. On Day 42 after ovulation, a small quantity of fluid was detected in the uterine horn, which typically indicates the presence of a developing conceptus. Repeated inspections followed what appeared to be a normal pregnancy until Day 116. However, on Day 124, signs of embryonic life were absent. Progestagen concentrations started declining two weeks later, reaching baseline levels one month after embryonic death. Retrospectively, ultrasound examination revealed several abnormalities in the uterine horn. Besides an existing leiomyoma, multiple small cystic structures had formed in the endometrium at the implantation site and later in the placenta. These pathological findings were considered as possible contributors to the early pregnancy failure. PCR for endotheliotropic elephant herpes virus (EEHV) (which had occurred previously in the herd) as well as serology for other infectious organisms known to cause abortion in domestic animals did not yield any positive results. Although no definitive reason was found for this pregnancy to abort, this ultrasonographically and endocrinologically documented study of an early pregnancy loss provides important insights into the resorption process in Asian elephants.

Are all contraceptive failures unintended pregnancies? Evidence from the 1995 National Survey of Family Growth.

The incidence of unintended pregnancy has long been used as a primary indicator of the state of reproductive health. However, the definition--and therefore the measurement--of this indicator has been elusive. Data from the 1995 National Survey of Family Growth (NSFG) were used to compare levels of unintended pregnancy among contraceptive users based on two definitions--the standard definition based on women's reports of contraceptive failure, and the NSFG definition based on pregnancy timing (wanted then, wanted later, or not wanted then or in the future). An attitudinal scale was used to examine women's feelings about their unintended pregnancy. Of pregnancies classified as contraceptive failures under the standard definition, only 68% were unintended pregnancies--94% of those ending in abortion and 60% of those ending in birth. Just 59% of women with a contraceptive failure classified as an unintended pregnancy reported feeling unhappy or very unhappy about their pregnancy, while 90% of those with a failure classified as an intended pregnancy reported being happy or very happy. Measures of wantedness based on women's feelings about their pregnancy may correlate more closely with important pregnancy outcomes than do traditional measures of intendedness.

The aim of this study was to report outcome of subsequent pregnancy after early-onset preeclampsia in first pregnancy, and to evaluate potential risk factors for recurrence of preeclampsia and preterm delivery. Reproductive follow-up data were obtained for women with a history of early-onset preeclampsia, resulting in delivery before 34 weeks of gestation at the University Medical Center Utrecht, The Netherlands, between July 1993 and September 2002. The relative contributions of demographic data, outcome variables of first pregnancy, and common thrombophilias to the recurrence risk of preeclampsia and preterm delivery in subsequent pregnancy, were estimated by Cox proportional hazard models. Subsequent pregnancy outcome data were available for 120 women. Overall, preeclampsia reoccurred in the second pregnancy in 30 women (25%). However, 6 women delivered before 34 weeks of gestation (5%), 20 women between 34 and 37 weeks of gestation (17%), and 94 women after 37 weeks of gestation (78%). Forty-one women (34%) had an uneventful pregnancy. Recurrence rates for preeclampsia or preterm delivery were not related to severity of first pregnancy complications, including delivery before 28 weeks of gestation, occurrence of hemolysis, elevated liver enzymes, and low platelet count syndrome, small-for-gestational age infants, and to hereditary or acquired thrombophilias. Chronic hypertension was related to a higher recurrence risk of preeclampsia in the second pregnancy (hazard ratio 2.1, 95% CI 1.0-4.4), and smoking was related to a higher recurrence risk of preterm birth (hazard ratio 2.4, 95% CI 1.1-5.6). Outcomes of subsequent pregnancy after first pregnancy with early-onset preeclampsia is generally favorable.

Shifts in color discrimination during early pregnancy.

Orbán, Levente L; Dastur, Farhad N

2012-05-25

The present study explores two hypotheses: a) women during early pregnancy should experience increased color discrimination ability, and b) women during early pregnancy should experience shifts in subjective preference away from images of foods that appear either unripe or spoiled. Both of these hypotheses derive from an adaptive view of pregnancy sickness that proposes the function of pregnancy sickness is to decrease the likelihood of ingestion of foods with toxins or teratogens. Changes to color discrimination could be part of a network of perceptual and physiological defenses (e.g., changes to olfaction, nausea, vomiting) that support such a function. Participants included 13 pregnant women and 18 non-pregnant women. Pregnant women scored significantly higher than non-pregnant controls on the Farnsworth-Munsell (FM) 100 Hue Test, an objective test of color discrimination, although no difference was found between groups in preferences for food images at different stages of ripeness or spoilage. These results are the first indication that changes to color discrimination may occur during early pregnancy, and is consistent with the view that pregnancy sickness may function as an adaptive defense mechanism.

Sympathetic activation during early pregnancy in humans

Sympathetic activity has been reported to increase in normotensive pregnant women, and to be even greater in women with gestational hypertension and preeclampsia at term. Whether sympathetic overactivity develops early during pregnancy, remaining high throughout gestation, or whether it only occurs at term providing the substrate for hypertensive disorders is unknown. We tested the hypothesis that sympathetic activation occurs early during pregnancy in humans. Eleven healthy women (29 ± 3 (SD) years) without prior hypertensive pregnancies were tested during the mid-luteal phase (PRE) and early pregnancy (EARLY; 6.2 ± 1.2 weeks of gestation). Muscle sympathetic nerve activity (MSNA) and haemodynamics were measured supine, at 30 deg and 60 deg upright tilt for 5 min each. Blood samples were drawn for catecholamines, direct renin, and aldosterone. MSNA was significantly greater during EARLY than PRE (supine: 25 ± 8 vs. 14 ± 8 bursts min−1, 60 deg tilt: 49 ± 14 vs. 40 ± 10 bursts min−1; main effect, P < 0.05). Resting diastolic pressure trended lower (P = 0.09), heart rate was similar, total peripheral resistance decreased (2172 ± 364 vs. 2543 ± 352 dyne s cm−5; P < 0.05), sympathetic vascular transduction was blunted (0.10 ± 0.05 vs. 0.36 ± 0.47 units a.u.−1 min−1; P < 0.01), and both renin (supine: 27.9 ± 6.2 vs. 14.2 ± 8.7 pg ml−1, P < 0.01) and aldosterone (supine: 16.7 ± 14.1 vs. 7.7 ± 6.8 ng ml−1, P = 0.05) were higher during EARLY than PRE. These results suggest that sympathetic activation is a common characteristic of early pregnancy in humans despite reduced diastolic pressure and total peripheral resistance. These observations challenge conventional thinking about blood pressure regulation during pregnancy, showing marked sympathetic activation occurring within the first few weeks of conception, and may provide the substrate for pregnancy induced cardiovascular complications.

The author determined pregnancy specific beta 1-glycoprotein in 109 women with threatened early pregnancy as 32 of the women suffered from abortus imminens with several unsuccessful pregnancies in the past as well as 67 women with abortus incipiens with bleeding ex utero. The author established that 87% of women with abortus imminens and preserved pregnancies had values of beta 1-glycoprotein close to those of normal pregnancy for the respective gestational week. 93% of women with abortus incipiens preserved pregnancies till term, but the specific glycoprotein was with in normal ranges. Spontaneous abortion occurred in 7% of women with low values under the 10th percentile. The present study show that examination of pregnancy specific beta 1-glycoprotein in women with threatened early pregnancy is of prognostic significance for the outcome of pregnancy.

It has been suggested that women with early miscarriage or ectopic pregnancy are best cared for in dedicated units which offer rapid and definitive ultrasonographic and biochemical assessment at the initial review of the patient. To describe the current protocols for the assessment and treatment of women with early miscarriage or ectopic pregnancy as reported by Nigerian Gynecologists, and determine if dedicated early pregnancy services such as Early Pregnancy Assessment Units could be introduced to improve care. A cross-sectional survey of Nigerian Gynecologists attending the 46 th Annual Scientific Conference of the Society of Gynaecology and Obstetrics of Nigeria. This was a questionnaire-based study. Data analysis was by descriptive statistics using Statistical Package for the Social Sciences software, version 17.0 for Windows (IBM Corporation, Armonk, NY, USA). A total of 232 gynecologists working in 52 different secondary and tertiary health facilities participated in the survey. The mean age of the respondents was 42.6 ± 9.1 years (range 28-70 years). The proportion of gynecologists reporting that women with early miscarriage or ectopic pregnancy were first managed within the hospital general emergency room was 92%. The mean reported interval between arrival in hospital and first ultrasound scan was 4.9 ± 1.4 hours (range ½-8 hours). Transvaginal scan was stated as the routine initial imaging investigation by only 17.2% of respondents. Approximately 94.8% of respondents felt that dedicated early pregnancy services were feasible and should be introduced to improve the care of women with early miscarriage and ectopic pregnancy. Reported protocols for managing early miscarriage or ectopic pregnancy in many health facilities in Nigeria appear to engender unnecessary delays and avoidable costs, and dedicated early pregnancy services could be both useful and feasible in addressing these shortcomings in the way women with such conditions are currently managed.

To determine the etiology, clinical features and outcome of fulminant hepatic failure in pregnancy. An observational hospital based study was conducted at Isra University hospital Hyderabad from 1st March 2009 to 28th February 2010. Total 1192 obstetric patients were admitted in obstetrics & gynaecology department during this period, of whom 52 were with Fulminant hepatic failure in pregnancy and were included in this study. A pre-designed structured proforma was used. All patients had clinical history and underwent a physical examination. Routine laboratory tests, liver function tests and viral serology were performed in all cases. All results were analyzed on statistical software SPSS version 11. Frequencies and percentages were calculated, the final outcome was recorded. Out of 52, 6 (11.5%) presented in the first trimester, 4 (7.6%) in the second trimester and 42 (80.7%) were in their 3rd trimester of pregnancy. Etiology of the disease was Hepatitis E in 28 (53.8%), Hepatitis B in 9 (17.3%), Hepatitis C in 7 (13.5%) HELLP syndrome in 7 (13.5%) and acute fatty liver of pregnancy in 1 (3.57%) case. Maternal mortality was 15 (28.8%) and foetal mortality was 40 (77%). Only 12 (23.1%) new born remained alive. Fulminant hepatic failure in pregnancy has very high foetal and maternal mortality which is mostly due to viral hepatitis E.

Heart disease, present in 0.5% to 3% of pregnant women, is an important cause of morbidity and the leading cause of death among pregnant women in the developed world. Certain heart conditions are associated with an increased risk of heart failure during pregnancy or the postpartum period; for these conditions, management during pregnancy benefits from multidisciplinary care at a center with expertise in pregnancy and heart disease. This article focuses on cardiac risks and management strategies for women with acquired and congenital heart disease who are at increased risk of heart failure during pregnancy.

Approximately one-third of pregnancies end in loss; however, the natural history of early pregnancy loss, including signs and symptoms preceding loss, has yet to be fully described and its underlying mechanisms fully understood. We searched PubMed/MEDLINE and Embase to identify articles with prospective ascertainment of signs and symptoms, including vaginal bleeding, nausea, and vomiting, of pregnancy loss < 20 weeks gestation in spontaneous conceptions to ascertain existing literature on symptomatology of pregnancy loss. Two preconception and 16 pregnancy cohort studies that ascertained information on bleeding and/or nausea/vomiting prior to pregnancy loss ascertainment were included. Data from these studies indicated increased risk of loss with vaginal bleeding and decreased risk of loss with nausea/vomiting, though these studies were mostly comprised of pregnancies surviving into late first trimester. While such associations are biologically plausible, these study designs are subject to bias, given recruitment of women at later gestational ages and reliance on women presenting to care. Reporting symptoms to clinicians and over long periods may introduce reporting error. Data gaps remain regarding (1) relationships between signs and symptoms and losses occurring very early, prior to care entry; (2) empirical testing of whether relationships between signs and symptoms and loss differ across gestational age; (3) whether similar relationships between signs and symptoms and loss are observed in populations using assisted reproductive technologies; (4) the patterning of multiple signs and symptoms in relation to loss; and (5) how hormonal and physiologic adaptions to early pregnancy relate to symptomatology and pregnancy loss.

Antenatal anxiety symptoms are not only a health problem for the expectant mother. Research has found that maternal anxiety may also have an impact on the developing baby. Therefore, it is important to estimate the prevalence of maternal anxiety and associated factors. The current study aims to estimate the prevalence of anxiety symptoms during the first trimester of pregnancy and to identify associated risk factors. Secondly, to investigate other factors associated with anxiety during early pregnancy including fear of childbirth and a preference for cesarean section. In a population-based community sample of 1,175 pregnant women, 916 women (78%) were investigated in the first trimester (gestation week 8-12). The Hospital Anxiety Depression Scale (HADS-A) was used to measure anxiety symptoms. The prevalence of anxiety symptoms (HADS-A scores≥8 during pregnancy) was 15.6% in early pregnancy. Women under 25 years of age were at an increased risk of anxiety symptoms during early pregnancy (OR 2.6, CI 1.7-4.0). Women who reported a language other than Swedish as their native language (OR 4.2, CI 2.7-7.0), reported high school as their highest level of education (OR 1.6, CI 1.1-2.3), were unemployed (OR 3.5, CI 2.1-5.8), used nicotine before pregnancy (OR 1.7, CI 1.1-2.5), and had a self-reported psychiatric history of either depression (OR 3.8, CI 2.6-5.6) or anxiety (OR 5.2, CI 3.5-7.9) before their current pregnancy were all at an increased risk of anxiety symptoms during early pregnancy. Anxiety symptoms during pregnancy increased the rate of fear of birth (OR 3.0, CI 1.9-4.7) and a preference for cesarean section (OR 1.7, CI 1.0-2.8). Caregivers should pay careful attention to history of mental illness to be able to identify women with symptoms of anxiety during early pregnancy. When presenting with symptoms of anxiety, the women might need counseling and or treatment in order to decrease her anxiety.

To describe changes in consumption of different types of beverages from pre-pregnancy to early pregnancy, and to examine associations with maternal age, educational level and BMI. Cross-sectional design. Participants answered an FFQ at inclusion into a randomized controlled trial, the Fit for Delivery (FFD) trial, in median gestational week 15 (range: 9-20), reporting current consumption and in retrospect how often they drank the different beverages pre-pregnancy. Eight local antenatal clinics in southern Norway from September 2009 to February 2013. Five hundred and seventy-five healthy pregnant nulliparous women. Pre-pregnancy, 27 % reported drinking alcohol at least once weekly, compared with none in early pregnancy (P<0.001). The percentage of women drinking coffee (38 % v. 10 %, P<0.001), sugar-sweetened beverages (10 % v. 6 %, P=0.011) and artificially sweetened beverages (12 % v. 9 %, P=0.001) at least daily decreased significantly from pre-pregnancy to early pregnancy, while the percentage of women who reported to drink water (85 % v. 92 %, P<0.001), fruit juice (14 % v. 20 %, P=0.001) and milk (37 % v. 42 %, P=0.001) at least daily increased significantly. From pre-pregnancy to early pregnancy higher educated women reduced their consumption frequency of coffee significantly more than women with lower education. Older women reduced their consumption frequency of coffee and artificially sweetened beverages and increased their consumption frequency of fruit juice and milk significantly more than younger women. There is a significant change in beverage consumption from pre-pregnancy to early pregnancy among Norwegian nulliparous women.

Women of child bearing age that regularly drink alcohol are at risk for drinking in early pregnancy. Evidence indicates a majority of women stop alcohol consumption on pregnancy recognition. However, there is a dearth of studies reporting on patterns and correlates of drinking in early pregnancy prior to stopping on pregnancy recognition, which the current study aims to address. In 2005, a New Zealand nationwide cross-sectional survey was conducted on a random sample of 1,256 women aged 16-40 years. Data were collected via an interviewer-administered questionnaire using a web-assisted telephone interviewing system. Of the 1,256 women who participated, 127 (10 %) were currently pregnant and 425 women (34 %) were previously pregnant. Half of currently pregnant women and 37 % of previously pregnant women reported that they ceased drinking on recognising pregnancy. Women categorised as "risky drinkers" and those aged 16-24 years had higher odds to drink and binge drink in early pregnancy, compared with non-risky drinkers and women of other age categories respectively. A majority of women stop alcohol consumption on pregnancy recognition but prior to this, drink at levels posing a risk for the developing foetus. Women most at risk for drinking and binge drinking in early pregnancy were younger in age and exhibited risky drinking behaviour prior to pregnancy. A targeted intervention to reduce the risk for an alcohol exposed pregnancy is warranted for sexually active younger women in New Zealand and elsewhere.

Fanconi anaemia is a rare inherited disease characterized by congenital abnormalities, progressive bone marrow failure and predisposition to malignancy. Successful pregnancies in transplanted patients have been reported. In this paper we will describe the pregnancy of a patient with Fanconi anaemia without transplantation. A 34-year-old nulliparous woman with Fanconi anaemia was referred to our institution. Pregnancy was complicated by progressive pancytopenia and two severe infections. C-section was performed at 36 weeks. Both infant and mother are well. Successful pregnancy in a Fanconi anaemia patient with bone marrow failure is possible. The mode of delivery in patients with bone marrow failure should be determined by obstetric indications. The case highlights the safe outcome of the pregnancy with strict clinical and laboratory control by a multidisciplinary team.

Elevated lipid levels during late pregnancy are associated with complications and adverse outcome for both mother and newborn. However, it is inconclusive whether a disturbed lipid profile during early pregnancy has similar negative associations. Our objective was to investigate whether nonfasting maternal total cholesterol and triglyceride levels during early pregnancy are associated with six major adverse pregnancy outcomes. Data were derived from the Amsterdam Born Children and Their Development (ABCD) cohort study. Random blood samples of nonfasting total cholesterol and triglyceride levels were determined during early gestation (median = 13, interquartile range = 12-14 wk). Outcome measures were pregnancy-induced hypertension (PIH), preeclampsia, preterm birth, small/large for gestational age (SGA/LGA), and child loss. Only nondiabetic women with singleton deliveries were included; the baseline sample consisted of 4008 women. Analysis for PIH and preeclampsia were performed in nulliparous women only (n = 2037). Mean (sd) triglyceride and total cholesterol levels were 1.33 (0.55) and 4.98 (0.87) mmol/liter, respectively. The incidence of pregnancy complications and perinatal outcomes were as follows: PIH, 4.9%; preeclampsia, 3.7%; preterm birth, 5.3%; SGA, 9.3%; LGA, 9.3%; and child loss, 1.4%. After adjustments, every unit increase in triglycerides was linearly associated with an increased risk of PIH [odds ratio (OR) = 1.60, P = 0.021], preeclampsia (OR = 1.69, P = 0.018), LGA (OR = 1.48, P < 0.001), and induced preterm delivery (OR = 1.69, P = 0.006). No associations were found for SGA or child loss. Total cholesterol was not associated with any of the outcome measures. Elevated maternal triglyceride levels measured during early pregnancy are associated with pregnancy complications and adverse pregnancy outcomes. These results suggest that future lifestyle programs in women of reproductive age with a focus on lowering triglyceride levels (i.e. diet, weight

Reducing unintended pregnancies: a microsimulation of contraceptive switching, discontinuation, and failure patterns in france.

Although the rate of contraceptive use in France is high, more than one-third of pregnancies are unintended. We built a dynamic microsimulation model that applies data from the French COCON study on method switching, discontinuation, and failure rates to a hypothetical population of 20,000 women, followed for five years. We use the model to estimate the adjustment factor needed to make the survey data fit the demographic profile of France by adjusting for underreporting of contraceptive nonuse and abortion. We then test three behavior-change scenarios that could reduce unintended pregnancies: decreasing method failure, increasing time using effective methods, and increasing switching from less effective to more effective methods. Our model suggests that decreasing method failure is the most effective means of reducing unintended pregnancies, but we found that all of the scenarios reduced unintended pregnancies by at least 25 percent. Dynamic microsimulations may have great potential in reproductive health research and prove useful for policymakers. © 2014 The Population Council, Inc.

Since 2007 the Danish Health and Medicines Authority has advised total alcohol abstinence from the time of trying to conceive and throughout pregnancy. The prevalence of binge drinking among pregnant Danish women has nevertheless been reported to be up to 48 % during early pregnancy. Since the introduction of the recommendation of total abstinence, no studies have examined pre-pregnancy lifestyle and reproductive risk factors associated with this behaviour in a Danish context. The aims of this study were therefore to describe the prevalence of weekly alcohol consumption and binge drinking in early pregnancy among women living in the capital of Denmark. Secondly to identify pre-pregnancy lifestyle and reproductive risk factors associated with binge drinking during early pregnancy. Data were collected from September 2012 to August 2013 at the Department of Obstetrics, Rigshospitalet, Copenhagen, Denmark. Self-reported information on each woman's socio-demographic characteristics, medical history, and lifestyle factors including alcohol habits was obtained from an electronic questionnaire filled out as part of the individual medical record. Descriptive analysis was conducted and multivariate logistic regression analysis was used to assess the potential associated risk factors (adjusted odds ratio (aOR)). Questionnaires from 3,238 women were included. A majority of 70 %, reported weekly alcohol consumption before pregnancy. The prevalence decreased to 3 % during early pregnancy. The overall proportion of women reporting binge drinking during early pregnancy was 35 % (n = 1,134). The following independent risk factors for binge drinking in early pregnancy were identified: lower degree of planned pregnancy, smoking and alcohol habits before pregnancy ((1 unit/weekly aOR 4.48, CI: 3.14 - 6.40), (2-7 units aOR 10.23, CI: 7.44-14.06), (≥8 units aOR 33.18, CI: 19.53-56.36)).

An early and accurate diagnosis of reproductive dysfunctions or aberrations is crucial to better reproductive management in livestock. High reproductive efficiency is a prerequisite for high life-time production in dairy animals. Early pregnancy diagnosis is key to shorten the calving interval through early identification of open animals and their timely treatment and rebreeding so as to maintain a postpartum barren interval close to 60 days. A buffalo, the most important dairy animal in the Indian subcontinent, is known for problems related to high calving interval, late puberty, and high incidence of anestrus. Lack of reliable cow-side early pregnancy diagnosis methods further aggravates the situation. Several methods of pregnancy diagnosis are being practiced in bovine species, yet none qualifies as the ideal pregnancy diagnosis method due to the inherent limitations of sensitivity, accuracy, specificity, speed, and ease of performing the test. The advancement of molecular techniques like proteomics and their applications in animal research has given a new hope to look for pregnancy biomarker molecules in these animals. This review attempts to examine common pregnancy diagnosis methods available for dairy animals, while assessing the usefulness of the modern technologies in detecting novel pregnancy markers and designing future strategies for research in this area.

A healthy diet is important for pregnancy outcome and the current and future health of woman and child. The aims of the study were to explore the changes from pre-pregnancy to early pregnancy in consumption of fruits and vegetables (FV), and to describe associations with maternal educational level, body mass index (BMI) and age. Healthy nulliparous women were included in the Norwegian Fit for Delivery (NFFD) trial from September 2009 to February 2013, recruited from eight antenatal clinics in southern Norway. At inclusion, in median gestational week 15 (range 9-20), 575 participants answered a food frequency questionnaire (FFQ) where they reported consumption of FV, both current intake and recollection of pre-pregnancy intake. Data were analysed using a linear mixed model. The percentage of women consuming FV daily or more frequently in the following categories increased from pre-pregnancy to early pregnancy: vegetables on sandwiches (13 vs. 17%, p <0.01), other vegetables (11 vs. 14%, p = 0.01), fruits (apples, pears, oranges or bananas) (24 vs. 41%, p < 0.01), other fruits and berries (8 vs. 15%, p < 0.01) and fruits and vegetables as snacks (14 vs. 28%, p < 0.01). The percentage of women who reported at least daily consumption of vegetables with dinner (22% at both time points) was stable. A higher proportion of older women increased their consumption of vegetables and fruits as snacks from pre-pregnancy to early pregnancy compared to younger women (p=0.04). We found an increase in the proportion of women consuming FV daily or more frequently from pre-pregnancy to early pregnancy.

Endometrial vascular changes similar to atherosclerosis of toxemia of pregnancy were described and graded in 217 consecutive endometrial biopsies of known early intrauterine pregnancy. Severe vascular changes were found in 23.5% of cases. Control material consisting of endometrial biopsies of patients with known cases of tubal ectopic pregnancy and various non-pregnancy menstrual disorders showed minimal or no changes except in one case. A parallel study of Aria-Stella phenomenon in 110 cases of uterine pregnancy showed significant changes in only 3.6% of patients. It is obvious that in these cases of positive Arias-Stella findings, the possibility of an extrauterine pregnancy could not be discarded on histologic grounds alone. The authors suggest the use of the vascular changes of the more severe histologic degree as described in this article as a positive or strongly suspicious marker for intrauterine pregnancy whenever this is needed.

Excessive cytokine inflammatory response due to chronic or superphysiological level of microbial infection during pregnancy leads to pregnancy complications such as early pregnancy defects/loss and preterm birth. Bacterial toxin lipopolysaccharide (LPS), long recognized as a potent proinflammatory mediator, has been identified as a risk factor for pregnancy complications. Alkaline phosphatase (AP) isozymes have been shown to detoxify LPS by dephosphorylation. In this study, we examined the role of alkaline phosphatase (AP) in mitigating LPS-induced early pregnancy complications in mice. We found that 1) the uterus prior to implantation and implantation sites following embryo implantation produce LPS recognition and dephosphorylation molecules TLR4 and tissue non-specific AP (TNAP) isozyme, respectively; 2) uterine TNAP isozyme dephosphorylates LPS at its sites of production; 3) while LPS administration following embryo implantation elicits proinflammatory cytokine mRNA levels at the embryo implantation sites (EISs) and causes early pregnancy loss, dephosphorylated LPS neither triggers proinflammatory cytokine mRNA levels at the EISs nor induces pregnancy complications; 4) AP isozyme supplementation to accelerate LPS detoxification attenuates LPS-induced pregnancy complications following embryo implantation. These findings suggest that a LPS dephosphorylation strategy using AP isozyme may have a unique therapeutic potential to mitigate LPS- or Gram-negative bacteria-induced pregnancy complications in at-risk women.

This study examined the associations between intimate partner violence (IPV) during pregnancy, mother-to-infant bonding failure, and postnatal depressive symptoms at 1 month postnatal. This study also examined if these relationships would be mediated by antenatal depressive symptoms. This study was a prospective cohort study that investigated effects between the third trimester of pregnancy and 1 month after childbirth. The Japanese version of the Index of Spouse Abuse (ISA), the Japanese version of the Mother-Infant Bonding Scale (MIBS), and the Japanese version of the Hospital Anxiety and Depression Scale (HADS) were used to measure IPV during pregnancy, bonding failure with infants, and depressive symptoms during pregnancy and the postnatal period respectively. Structural equation modeling (SEM) was used to find the associations between those four variables. The final path model of the SEM showed good fit with the data. IPV during pregnancy was associated with mother-to-infant bonding failure at 1 month postnatal, whereas IPV during pregnancy was not significantly associated with postnatal depressive symptoms at 1 month postnatal. In addition, this study demonstrated that the associations between IPV during pregnancy, mother-to-infant bonding failure, and postnatal depressive symptoms at 1 month postnatal were mediated by antenatal depressive symptoms. The results of this study indicated the need for interventions for IPV and psychological health care for abused pregnant women to prevent antenatal depressive symptoms in prenatal health settings. Those interventions by perinatal health professionals would help to prevent bonding failure with infants and postnatal depressive symptoms after childbirth.

The paper examines recent time trends, explores potentially influential background factors and discusses prevention strategies of pregnancy among girls under 15 years of age in Japan. Using Japanese government data, we first analyzed time trends of early adolescence (<15 years of age) abortion, live birth and child sexual abuse from 2003 to 2010. Second, we analyzed ecological correlations of early adolescent pregnancy (abortion, live birth and stillbirth) with pregnancy in other age groups, child sexual abuse, and indicators of juvenile victimization and juvenile delinquency, using prefectural data. We found that rates of both abortion and live birth in early adolescents have increased since 2005 (annual percent change 5.3% and 2.3%, respectively), despite declining rates in older age groups. The abortion ratio in early adolescence remained the highest among all age groups in Japan. The early adolescent pregnancy rate showed significant correlation with the rates of juvenile victimization of welfare crimes (obscenity, alcohol drinking, smoking and drug use) (Spearman's rank correlation coefficient [rs] = 0.42, P = 0.00) and juvenile delinquency among junior high school students (12-14 years of age) (rs = 0.69, P = 0.00). The observed rise in rates of abortion, live birth and child sexual abuse among early adolescents along with strong ecological correlations of their pregnancy rate with juvenile victimization and delinquency indicators suggests that epidemiological investigation and public health programs at the individual and community levels are needed to address the complex social roots of these trends and to produce effective improvements in early adolescent reproductive health. © 2013 The Authors.

A relationship between maternal weight and unintended pregnancy has previously been reported. Researchers have found women who are overweight and obese women are less likely to use contraception, and more likely to have unplanned pregnancies, thus limiting their ability to optimise their health before conception. This study sought to examine the relationship between pregnancy intention and body mass index (BMI) amongst women attending a service managing early pregnancy complications. The cross-sectional descriptive study (n = 550) was conducted from November 2013 to February 2015 in Sydney, Australia. It documented women's pregnancy intention using a self-completed questionnaire incorporating a validated pregnancy intention scale and measuring women's height and weight to calculate their BMI using the WHO classification of anthropometry and adjusting for cut-offs in Asian populations. Socio-demographic characteristics were also documented. The respondents were ethnically diverse with over a third defining themselves as Asian (36%; 196). Forty-four per cent of women (239) had clearly intended their pregnancy, 39% (212) were ambivalent and 18% (99) had not intended to conceive. Forty-nine per cent (263) of women were overweight or obese. No relationship was found between pregnancy intention and BMI. Fewer than half the women with early pregnancy complications clearly intended to be pregnant. Contrary to previous research, pregnancy intention was not associated with maternal weight. Underutilised opportunities for lifestyle and preconception education exist to address the impact of modifiable maternal behaviours on future pregnancies and to provide contraception counselling to those not wishing to conceive. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Ultrasound imaging in the management of bleeding and pain in early pregnancy.

Bleeding and pain are experienced by 20% of women during the first trimester of pregnancy. Although most pregnancies complicated by pain and bleeding tend to progress normally, these symptoms are distressing for woman, and they are also associated with an increased risk of miscarriage and ectopic pregnancy. Ultrasound is the first and often the only diagnostic modality that is used to determine location of early pregnancy and to assess its health. Ultrasound is an accurate, safe, painless and relatively inexpensive diagnostic tool, which all contributed to its widespread use in early pregnancy. Pain and bleeding in early pregnancy are sometimes caused by concomitant gynaecological, gastrointestinal, and urological problems, which could also be detected on ultrasound scan. In women with suspected intra-abdominal bleeding, ultrasound scan can be used to detect the presence of blood and provide information about the extent of bleeding. In this chapter, we comprehensively review the use of ultrasound in the diagnosis and management of early pregnancy complications. We include information about the diagnosis of gynaecological and other pelvic abnormalities, which could cause pain or bleeding in pregnancy. We also provide a summary of the current views on the safety of ultrasound in early pregnancy. Copyright © 2014 Elsevier Ltd. All rights reserved.

Premenstrual symptoms are associated with psychological and physical symptoms in early pregnancy.

The reproductive life of women is characterised by a number of distinct reproductive events and phases (e.g. premenstrual phase, peripartum, perimenopause). The hormonal transitions during these phases are often associated with both psychological and physical symptoms. Associations between these reproductive phases have been shown by numerous studies. However, the relationship between symptoms during the premenstrual phase and during early pregnancy has received little attention thus far, although early pregnancy is a time of dramatic hormonal as well as physical adaptation. Findings are based on a prospective longitudinal study with N = 306 pregnant women (MARI study). Three hundred five women that had menstrual bleeding in the year before pregnancy rated the severity of psychological and physical symptoms during premenstrual phases in the year preceding pregnancy. Besides this, they rated the severity of the same symptoms during early pregnancy (weeks 10 to 12 of gestation). The overall severity of premenstrual symptoms was significantly associated with the overall severity of early pregnancy symptoms (b = 0.4, 95% CI = 0.3-0.5; p < 0.001). The overall severity of early pregnancy symptoms was best predicted by the severity of premenstrual irritability. The best predictor for a particular symptom in early pregnancy mostly was the corresponding premenstrual symptom. The associations between premenstrual and early pregnancy symptoms support the reproductive hormone sensitivity hypothesis that some women are prone to repeatedly experience specific psychological and physical symptoms during different reproductive phases. The findings further imply that the nature of symptoms might be rather consistent between different reproductive phases.

Predictive markers of failure of induction of labour in term pregnancy were evaluated. A prospective study including 245 women attending induction of labour was performed. The inclusion criteria were singleton pregnancies, gestational age 37-42 weeks and the main outcomes were failure of induction, induction to delivery interval and mode of delivery. Women with a longer cervical length prior to induction (CLpi) had a higher rate of failure of induction (30.9 ± 6.8 vs. 23.9 ± 9.3, p < .001). BMI was higher and maternal height was lower in the group of caesarean section compared to vaginal delivery (33.1 ± 8 vs. 29.3 ± 4.6, 160 ± 5 vs. 164 ± 5, p < .001, respectively). A shorter CLpi correlated with a shorter induction to delivery interval (R Pearson .237, p < .001). In the regression analysis, for failure of induction the only independent predictor was the CL prior to induction. Therefore, the CLpi is an independent factor for prediction of failure of induction of labour.

Obstetric patients comprise a limited portion of intensive care unit patients, but they often present with unfamiliar conditions and exhibit the potential for catastrophic deterioration. This study evaluated the maternal and neonatal outcomes of respiratory failure during pregnancy. Information on 71 patients at >25 weeks gestation in the ICU with respiratory failure was recorded between 2009 and 2013. The characteristics and outcomes of mothers and fetuses were determined through a retrospective chart review and evaluated using Student's t test, chi-square test, and Fisher's exact test. The leading causes of respiratory failure were postpartum hemorrhage and severe preeclampsia in the obstetric causes group and pneumonia in the nonobstetric causes group during pregnancy and the peripartum period. The non-obstetric causes group exhibited a higher incidence of acute respiratory distress syndrome and renal replacement therapy as well as requiring more ventilator days. The patients in the obstetric causes group showed significant improvement after delivery in the partial pressure of arterial oxygen to the fraction of inspired oxygen and peak inspiratory pressure decrease. Both groups exhibited high incidences of neonatal respiratory distress syndrome. Neonatal complications resulting from meconium aspiration syndrome (MAS) and sepsis were more common in the non-obstetric causes group; however, neurological development impairment was more common in the obstetric causes group. Obstetric cause was associated with longer ventilator free days and fewer episodes of ARDS after delivery. Neonatal complications resulting from different etiologies of respiratory failure were found to differ. Copyright © 2017. Published by Elsevier B.V.

The five most commonly reported physical health problems were as follows: exhaustion (86.9%), morning sickness (64.3%), back pain (45.6%), constipation (43.5%) and severe headaches or migraines (29.5%). Women scoring ≥ 13 on the EPDS reported a mean of six physical health problems compared with a mean of 3.5 among women scoring <13 on the EPDS. Women reporting five or more physical health problems had a three-fold increase in likelihood of reporting depressive symptoms (Adj OR=3.13, 95% CI 2.14-4.58) after adjusting for socio-demographic factors, including maternal age. the findings from this large multi-centre study show that women experiencing a greater number of physical health problems are at increased risk of reporting depressive symptoms in early pregnancy. early detection and support for women experiencing physical and psychological health problems in pregnancy is an important aspect of antenatal care. The extent of co-morbid physical and psychological health problems underlines the need for comprehensive primary health care as an integral component of antenatal care. Copyright © 2012 Elsevier Ltd.

Knowledge about factors that influence serum brain-derived neurotrophic factor (BDNF) concentrations during early pregnancy is lacking. The aim of the study is to examine the correlates of early pregnancy serum BDNF concentrations. A total of 982 women attending prenatal care clinics in Lima, Peru, were recruited in early pregnancy. Pearson's correlation coefficient was calculated to evaluate the relation between BDNF concentrations and continuous covariates. Analysis of variance and generalized linear models were used to compare the unadjusted and adjusted BDNF concentrations according to categorical variables. Multivariable linear regression models were applied to determine the factors that influence early pregnancy serum BDNF concentrations. In bivariate analysis, early pregnancy serum BDNF concentrations were positively associated with maternal age (r = 0.16, P < 0.001) and early pregnancy body mass index (BMI) (r = 0.17, P < 0.001), but inversely correlated with gestational age at sample collection (r = -0.21, P < 0.001) and C-reactive protein (CRP) concentrations (r = -0.07, P < 0.05). In the multivariable linear regression model, maternal age (β = 0.11, P = 0.001), early pregnancy BMI (β = 1.58, P < 0.001), gestational age at blood collection (β = -0.33, P < 0.001), and serum CRP concentrations (β = -0.57, P = 0.002) were significantly associated with early pregnancy serum BDNF concentrations. Participants with moderate antepartum depressive symptoms (Patient Health Questionnaire-9 (PHQ-9) score ≥ 10) had lower serum BDNF concentrations compared with participants with no/mild antepartum depressive symptoms (PHQ-9 score < 10). Maternal age, early pregnancy BMI, gestational age, and the presence of moderate antepartum depressive symptoms were statistically significantly associated with early pregnancy serum BDNF concentrations in low-income Peruvian women.

Background Nausea, retching and vomiting are very commonly experienced by women in early pregnancy. There are considerable physical and psychological effects on women who experience these symptoms. This is an update of a review of interventions for nausea and vomiting in early pregnancy previously published in 2003. Objectives To assess the effectiveness and safety of all interventions for nausea, vomiting and retching in early pregnancy, up to 20 weeks’ gestation. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (28 May 2010). Selection criteria All randomised controlled trials of any intervention for nausea, vomiting and retching in early pregnancy. We excluded trials of interventions for hyperemesis gravidarum which are covered by another review. We also excluded quasi-randomised trials and trials using a crossover design. Data collection and analysis Four review authors, in pairs, reviewed the eligibility of trials and independently evaluated the risk of bias and extracted the data for included trials. Main results Twenty-seven trials, with 4041 women, met the inclusion criteria. These trials covered many interventions, including acupressure, acustimulation, acupuncture, ginger, vitamin B6 and several antiemetic drugs. We identified no studies of dietary or other lifestyle interventions. Evidence regarding the effectiveness of P6 acupressure, auricular (ear) acupressure and acustimulation of the P6 point was limited. Acupuncture (P6 or traditional) showed no significant benefit to women in pregnancy. The use of ginger products may be helpful to women, but the evidence of effectiveness was limited and not consistent. There was only limited evidence from trials to support the use of pharmacological agents including vitamin B6, and anti-emetic drugs to relieve mild or moderate nausea and vomiting. There was little information on maternal and fetal adverse outcomes and on psychological, social or economic outcomes. We

It has been suggested that management system, milk yield, parity, body condition score and ambient temperature can significantly influence the rate of early pregnancy loss in dairy cattle. The objectives of this study were to establish the extent and patterns of early pregnancy loss from days 32 to 86 of gestation, and to check relationships between management system, milk yield, ambient temperature (quartile), body condition score, bull and parity on the early pregnancy loss rate for Simmental dairy cattle in Croatia. Animals were housed in two dairy farms with two different management systems (pasture based-group A, n=435 and intensive-group B, n=425) with a total of 151 heifers and 709 cows. Overall pregnancy losses were recorded in 67 (7.79%) animals, with late embryonic losses in 30 (44.77%) and early fetal losses in 37 (55.23%) animals (P>0.05). Early pregnancy losses were twofold higher in group B when compared to the group A (P<0.05). More than the half of pregnancy losses were recorded during the III quartile (P<0.05). There was no significant relationship between the paternal bull and pregnancy loss rate. Low body condition score (BCS 2-3) was associated with the highest, while BCS 3.25-4 showed the lowest pregnancy loss rate (P<0.05). The pregnancy loss rate increased in parallel with parity and milk yield increase. Copyright © 2011 Elsevier B.V. All rights reserved.

Background: Growth failure is associated with adverse consequences, but studies need to control adequately for confounding. Objective: We related height-for-age z scores (HAZs) and stunting at age 24 mo to adult human capital, marriage, fertility, health, and economic outcomes. Design: In 2002–2004, we collected data from 1338 Guatemalan adults (aged 25–42 y) who were studied as children in 1969–1977. We used instrumental variable regression to correct for estimation bias and adjusted for potentially confounding factors. Results: A 1-SD increase in HAZ was associated with more schooling (0.78 grades) and higher test scores for reading and nonverbal cognitive skills (0.28 and 0.25 SDs, respectively), characteristics of marriage partners (1.39 y older, 1.02 grade more schooling, and 1.01 cm taller) and, for women, a higher age at first birth (0.77 y) and fewer number of pregnancies and children (0.63 and 0.43, respectively). A 1-SD increase in HAZ was associated with increased household per capita expenditure (21%) and a lower probability of living in poverty (10 percentage points). Conversely, being stunted at 2 y was associated with less schooling, a lower test performance, a lower household per capita expenditure, and an increased probability of living in poverty. For women, stunting was associated with a lower age at first birth and higher number of pregnancies and children. There was little relation between either HAZ or stunting and adult health. Conclusion: Growth failure in early life has profound adverse consequences over the life course on human, social, and economic capital. PMID:24004889

To assess the value of serial hCG and progesterone serum level in the diagnosis of early pregnancy viability. It was a prospective cohort study. Women with a pregnancy of uncertain viability (PUV), defined as the presence of an intra-uterine embryo with a crown-rump length <7mm with no cardiac activity or an intra-uterine gestational sac size <25mm with no visible embryonic structure in a transvaginal ultrasound scan (TVS) were eligible. The diagnosis value of serial plasmatic hCG levels on the first day and 48h after as well as the initial progesterone level were evaluated to diagnose pregnancy viability. Pregnancy viability was assessed by TVS 7 to 14days after inclusion. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of an hCG H48/H0 ratio increase <11% to diagnose an early pregnancy loss were 70.6%, 100%, 100% and 85.3%, respectively. The sensitivity, specificity, PPV and NPV of a 6.2ng/ml progesterone level to diagnose an early pregnancy loss were 20%, 100%, 100% and 65.2%, respectively. The sensitivity, specificity, PPV and NPV of an hCG H48/H0 ratio increase >75% to diagnose a viable pregnancy were 100%, 31%, 45.9% and 100%, respectively. hCG H48/H0 ratio increase <11% was associated with early pregnancy loss in 100% of the cases. hCG H48/H0 ratio increase >75% was associated with 100% of viable pregnancies in 100% of the cases. Serial hCG levels alone permitted an early viability diagnosis within 48h for 41.1% of patients with PUV instead of 7 to 14days with TVS. Copyright © 2017 Elsevier B.V. All rights reserved.

Thrombophilia and Pregnancy Complications

Simcox, Louise E.; Ormesher, Laura; Tower, Clare; Greer, Ian A.

2015-01-01

There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage) and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction). Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

[Pregnancy in pulmonary arterial hypertension patients].

Rosengarten, Dror; Kramer, Mordechai R

2013-09-01

Pulmonary arterial hypertension (PAH) is a disorder defined by elevated mean pulmonary arterial pressure. PAH can be idiopathic or associated with a variety of medical conditions such as scleroderma, congenital heart disease, left heart failure, lung disease or chronic pulmonary thromboembolism. This progressive disease can cause severe right heart failure and death. Normal physiologic changes that occur during pregnancy may produce fatal consequences in PAH patients. Current guidelines recommend that pregnancy be avoided or terminated early in women with PAH. During the past decade, new advanced therapies for PAH have emerged gathering reports of successful pregnancies in patients with pulmonary hypertension. Substantial risk still exists and current recommendations have not changed. Nevertheless, in selected cases, if a patient insists on continuing the pregnancy, being fully aware of the risks involved, an intensive treatment approach should be implemented in experienced centers. This is necessary in order to control pulmonary hypertension during pregnancy and reduce the risk so as to improve outcomes. This review will focus on the pathophysiology of PAH in pregnancy and appropriate management during pregnancy, delivery and the post-partum period.

The public health challenge of early growth failure in India.

Young, M F; Martorell, R

Recent recognition of the early onset and high prevalence of wasting (30%) and stunting (20%) among infants 0-5 months in India draws attention to the need to understand the causes and develop prevention strategies. Such growth failure has dire consequences in the short (increased mortality) and long-term (loss of human capital and increased risk of chronic diseases). Food interventions before 6 months will increase morbidity/mortality through contamination in settings of poor sanitation and hygiene. Waiting to improve nutrition only after the initiation of complementary feeding at 6 months is a missed opportunity and may permanently alter life trajectory and potential. This underscores the importance of maternal nutrition. Iron and folic acid and protein energy supplementation during pregnancy are interventions that can improve maternal nutrition and birth outcomes. Maternal supplementation during lactation should be considered as a means to improve maternal and child outcomes, although the evidence needs strengthening. Support and counseling are also required to improve maternal diets and promote exclusive breastfeeding. Programs focused on improving maternal nutrition across the continuum of preconception, pregnancy and lactation are likely to have the greatest impact as mothers are central gatekeepers to the health and future of their children.

To assess the effect of early pregnancy on obstetric fistula. A prospective observational study was conducted among patients with obstetric fistula caused by a long obstructed labor who presented at Selian Lutheran Hospital, Tanzania, or Kitovu Hospital, Uganda, between January 1, 2015, and January 31, 2016. Demographic and clinical variables were evaluated. Among 270 patients, 162 (60.0%) experienced their first pregnancy up to 2 years after menarche (early group) and 108 (40.0%) experienced their first pregnancy more than 2 years after menarche (late group). No significant differences between the early and late groups were found for median age at presentation (30.0 vs 28.0 years), median parity (both 2.0), stillbirth (n=145 [89.5%] vs n=95 [88.0%]), median duration of labor (both 2.0 days), home delivery (n=31 [19.1%] vs n=17 [15.7%]), cesarean delivery (n=79 [48.8%] vs 58 [53.7%]), median time from obstetric fistula formation to presentation (48.0 vs 24.0 months), and obstetric fistula classifications. Obstetric fistula occurred during the first pregnancy in 99 (61.1%) women in the early group and 71 (65.7%) in the late group (P=0.440). Frequency of obstetric fistula during the first pregnancy is not increased among women who experience their first pregnancy within 2 years of menarche. © 2017 International Federation of Gynecology and Obstetrics.

Incidence, causes and consequences of pregnancy failure in viviparous lizards: implications for research and conservation settings.

PubMed

Hare, Kelly M; Cree, Alison

2010-01-01

Research on the causes of pregnancy failure in vertebrates has historically been mammal-focussed. However, live-birth (viviparity) has evolved multiple times, and is present in all other vertebrate taxa except Aves and Agnatha. Viviparous lizards (O. Squamata, excluding snakes and amphisbaenians) provide a valuable experimental group when studying major evolutionary events and some are also species of high conservation value. Consequently, both researchers and herpetoculturists often require high reproductive output from captive-held lizards. We reviewed the literature to determine potential or known causes of pregnancy failure for captive lizards. Pregnancy success across species averages approximately 86%, but varies extensively and does not appear to be related to embryonic stage when brought into captivity or level of placentation. Causes of pregnancy failure also vary among species, but correct thermal environments are vital to success, and providing adequate nutrition before vitellogenesis increases the number of viable offspring. A coordinated sequence of hormonal changes involving both pro-pregnancy and pro-labour factors is important for successful pregnancies, although uncertainty remains around the maternal concentrations of corticosterone that allow successful development. Several research areas commonly studied in mammals have yet to be explored or fully addressed in pregnant lizards, including impacts of toxins, parasites, UV light and nutritional quality. As viviparity has evolved over 100 times in lizards, and many different levels of placentation exist, pregnant lizards provide valuable models for studies in ecology and evolution and offer a useful comparison for studies on other viviparous vertebrates.

Exercise during pregnancy is associated with health benefits for both the mother and the fetus, and is therefore recommended in several national guidelines. Only few studies investigate whether these guideline recommendations are met. The aims of this study were 1. To assess the prevalence of pregnant women meeting the Danish recommendations for exercise during early pregnancy, 2. To identify pre-pregnancy factors associated with a lower probability for meeting the recommendations, and 3. To describe which types of exercise pregnant women prefer before and during pregnancy. We conducted a cross-sectional study based on a questionnaire during the first trimester among 7,915 women participating in the prospective Copenhagen Pregnancy Cohort. Associations were estimated by multivariate regression analyses. In early pregnancy, 38 % of the study population met the recommendation for exercise from the Danish Health and Medicines Authority (≥3.5 hours a week). Multiparity, previous miscarriage use of assisted reproductive technology, no engagement in exercise before pregnancy, smoking, pregnancy following assisted reproductive technology, overweight, not understanding Danish language and a low educational level were all factors associated a lower probability for meeting the recommendations. The preferred types of exercise before and during pregnancy were bicycling, brisk walking, running and strength training. The proportion of women engaged in any type of exercise decreased in early pregnancy with the exception of swimming and aquatic exercise. In this cohort, more than one-third met the Danish recommendation for exercise during early pregnancy. Exercise in pregnancy is still an issue to address because the most vulnerable groups of pregnant women do not exercise. This is a cause of concern because it may reflect social inequalities in health and highlights the need for a structural and systematic approach to preconception care and early antenatal counselling.

Miscarriage is a common and poorly understood adverse pregnancy outcome. In this study, the authors sought to evaluate the relation between self-reported use of prenatal vitamins in early pregnancy and the risk of miscarriage. Between 2000 and 2008, 4,752 US women were prospectively enrolled in Right From the Start. Information about vitamin use was obtained from a first-trimester interview. Discrete-time hazard models were used, candidate confounders were assessed, and the following variables were included in the model: study site, maternal age, gravidity, marital status, education, race/ethnicity, smoking, and use of progesterone in early pregnancy. Approximately 95% of participants reported use of vitamins during early pregnancy. A total of 524 women had a miscarriage. In the final adjusted model, any use of vitamins during pregnancy was associated with decreased odds of miscarriage (odds ratio = 0.43, 95% confidence interval: 0.30, 0.60) in comparison with no exposure. These results should be viewed in the context of a potentially preventive biologic mechanism mitigated by possible confounding by healthy behaviors and practices that are also associated with vitamin supplement use during pregnancy.

OBJECTIVE To estimate whether elevations of complement C3a early in pregnancy are predictive of the subsequent development of adverse pregnancy outcomes. METHODS A plasma sample was obtained from each enrolled pregnant woman before 20 weeks of gestation. The cohort (n=1,002) was evaluated for the development of adverse pregnancy outcomes defined as hypertensive diseases of pregnancy (gestational hypertension or preeclampsia), preterm birth (before 37 weeks of gestation), premature rupture of the membranes, pregnancy loss (during the embryonic and fetal period), intrauterine growth restriction, and the composite outcome of any adverse outcome. RESULTS One or more adverse pregnancy outcomes occurred in 211 (21%) of the cohort. The mean levels (ng/mL) of C3a in early pregnancy were significantly (P=<.001) higher among women with one or more adverse outcomes (858±435) compared with women with an uncomplicated pregnancy (741±407). Adjusted for parity and prepregnancy body mass index, women with levels of C3a in the upper quartile in early pregnancy were three times more likely to have an adverse outcome later in pregnancy compared with women in the lowest quartile (95% confidence interval, 1.8–4.8; P<.001). The link between early elevated C3a levels and adverse pregnancy outcomes was driven primarily by individual significant (P<.05) associations of C3a with hypertensive diseases of pregnancy, preterm birth, and premature rupture of the membranes. CONCLUSION Elevated C3a as early as the first trimester of pregnancy is an independent predictive factor for adverse pregnancy outcomes, suggesting that complement-related inflammatory events in pregnancy contribute to the subsequent development of poor outcomes at later stages of pregnancy.

To determine effects of per rectal amniotic sac palpation (ASP) for pregnancy diagnosis during early gestation on pregnancy loss in lactating cows. Controlled, randomized block design. 368 pregnant dairy cows. Pregnancy was detected via transrectal ultrasonography (TRUS) at day 29 (day of estrus = day 0), and cows were allocated into a control group (n = 167 cows) and ASP group (180). Control cows were not subjected to pregnancy diagnosis via palpation per rectum. Per rectal ASP was performed between days 34 and 43 by only 1 experienced veterinarian. All cows were reevaluated with TRUS on days 45, 60, and 90. 21 cows were removed because of illness. Pregnancy loss between days 29 and 90 occurred in 44 of 347 (12.7%) cows. Pregnancy loss for the control and ASP groups from days 29 to 90 occurred in 22 of 167 (13.2%) and 22 of 180 (12.2%) cows, respectively. Late embryonic pregnancy loss (days 29 to 45) for the control and ASP groups occurred in 18 (10.8%) and 15 (8.3%) cows, respectively. Early fetal pregnancy loss (days 46 to 60) for the control and ASP groups occurred in 2 of 149 (1.3%) and 6 of 165 (3.6%) cows, respectively, and late fetal pregnancy loss (days 61 to 90) for the same groups occurred in 2 of 147 (1.4%) and 1 of 159 (0.6%) cows, respectively. Pregnancy diagnosis via per rectal ASP during early gestation did not increase pregnancy loss in dairy cattle.

Inside stories: maternal representations of first time mothers from pre-pregnancy to early pregnancy.

PubMed

Hopkins, Julia; Clarke, David; Cross, Wendy

According to the psychoanalytical literature, it is during pregnancy that maternal representations of the mother-infant relationship become activated. Midwives who are engaged with the mother and the baby have not drawn upon this concept in their practice. In order for this to happen, it is important to understand better the nature of maternal representations and when they are activated from empirical studies. The research question is: what are the maternal representations of a group of first time mothers from pre-pregnancy, early pregnancy and to the first ultrasound. A narrative approach was used to gain insight into the maternal representations of first time pregnant womens' account of their representations. The analysis method was based on thematic approach. Fifteen women aged between 23 and 38 years. A midwives clinic attached to a tertiary hospital in Melbourne, Australia. First-time pregnant women's maternal representations were activated when a woman begins to plan her pregnancy ('the time is right'), again at the onset of physical changes to her body as a result of conception ('my body is changing'), and at the first early ultrasound at around twelve weeks ('it' is a real baby). Maternal representations are important for the midwife and pregnant women because this concept provides another understanding in relation to the psychological dimension of pregnancy.

Wong, M; O'Neill, S; Walsh, G; Smith, I E

2013-01-01

Premature ovarian failure and infertility following chemotherapy in early breast cancer (EBC) are major concerns for young women. The role of gonadotrophin-releasing hormone (GnRH) agonists with chemotherapy in EBC in reducing the incidence of chemotherapy-induced early menopause remains uncertain, and long-term data on the recovery of fertility are sparse. We report an audit of our experience with the GnRH agonist, goserelin (Zoladex®), used with chemotherapy to preserve ovarian function and maintain fertility. Pre-menopausal women were given goserelin subcutaneously every 28 days during chemotherapy, starting 0-14 days before treatment. The main clinical end point was recovery of menstruation after chemotherapy. The other end points were rate of successful conception and median time to recovery of menses. About 84% of 125 women recovered menstruation with the median time to recovery of 6 months (1-43 months), including 76% of 71 patients aged over 35. Of the 42 patients who attempted pregnancy, 71% (n=30) managed to achieve pregnancies. At the time of analysis, there were 42 pregnancies and 30 healthy deliveries. The GnRH agonist, goserelin, given with chemotherapy for EBC is associated with a low risk of long-term chemotherapy-induced amenorrhoea and a high chance of pregnancy. Further randomised trials are needed.

Maternal vitamin status contributes to clinical spontaneous abortion, but the role of B-vitamin and homocysteine status in subclinical early pregnancy loss is unknown. Three-hundred sixty-four textile workers from Anqing, China, who conceived at least once during prospective observation (1996-1998), provided daily urine specimens for up to 1 year, and urinary human chorionic gonadotropin was assayed to detect conception and early pregnancy loss. Homocysteine, folate, and vitamins B6 and B12 were measured in preconception plasma. Relative to women in the lowest quartile of vitamin B6, those in the third and fourth quartiles had higher adjusted proportional hazard ratios of conception (hazard ratio (HR)=2.2, 95% confidence interval (CI): 1.3, 3.4; HR=1.6, 95% CI: 1.1, 2.3, respectively), and the adjusted odds ratio for early pregnancy loss in conceptive cycles was lower in the fourth quartile (odds ratio=0.5, 95% CI: 0.3, 1.0). Women with sufficient vitamin B6 had a higher adjusted hazard ratio of conception (HR=1.4, 95% CI: 1.1, 1.9) and a lower adjusted odds ratio of early pregnancy loss in conceptive cycles (odds ratio=0.7, 95% CI: 0.4, 1.1) than did women with vitamin B6 deficiency. Poor vitamin B6 status appears to decrease the probability of conception and to contribute to the risk of early pregnancy loss in this population.

This study was to evaluate effects of high normal blood pressure (HNBP) in early pregnancy on total preeclampsia, early preeclampsia, and severe preeclampsia. We conducted a multicenter, national representative retrospective cohort study. HNBP was defined as systolic blood pressure between 130 and 140 mmHg or diastolic blood pressure between 85 and 90 mmHg. We used multivariable logistic regression to examine the associations of HNBP and the risks of above three types of preeclampsia. We included 58 054 women who were normotensive and nulliparous in early pregnancy. 4 809 (8.3%) fulfilled the definition of having HNBP, 16 682 (28.7%) were in normal blood pressure group, and 36 563 (63.0%) were in optimal blood pressure group. The incidence rates of total preeclampsia, early preeclampsia, and severe preeclampsia were 2.1% (1 217), 0.8% (491), and 1.4% (814), respectively. Compared to having optimal blood pressure, women with HNBP had significantly higher odds of total preeclampsia (odds ratio (OR) = 4.028, 95% confidence interval (CI) 3.377, 4.804), severe preeclampsia (OR = 3.542, 95% CI 2.851, 4.400), and early preeclampsia (OR = 8.163, 95% CI 6.219, 10.715). Our restricted cubic spline results supported the dose-response relationship between continuous blood pressure and the odds ratio of three types of preeclampsia. The fraction of early preeclampsia associated with prehypertension was 58.6%, which was higher than those of total preeclampsia (42.2%) or severe preeclampsia (40.5%). Women in early pregnancy with HNBP more likely develop total preeclampsia, early preeclampsia and severe preeclampsia, compared to those with optimal blood pressure. HNBP contribute more to early preeclampsia than severe preeclampsia. Our study provided robust epidemiological evidences for monitoring HNBP in early pregnancy to reduce the risks of preeclampsia.

Objectives: We assessed the association between the timing of pregnancy with the risk of postpartum virologic failure and loss from HIV care in South Africa. Design: This is a retrospective cohort study of 6306 HIV-positive women aged 15–49 at antiretroviral therapy (ART) initiation, initiated on ART between January 2004 and December 2013 in Johannesburg, South Africa. Methods: The incidence of virologic failure (two consecutive viral load measurements of >1000 copies/ml) and loss to follow-up (>3 months late for a visit) during 24 months postpartum were assessed using Cox proportional hazards modelling. Results: The rate of postpartum virologic failure was higher following an incident pregnancy on ART [adjusted hazard ratio 1.8, 95% confidence interval (CI): 1.1–2.7] than among women who initiated ART during pregnancy. This difference was sustained among women with CD4+ cell count less than 350 cells/μl at delivery (adjusted hazard ratio 1.8, 95% CI: 1.1–3.0). Predictors of postpartum virologic failure were being viremic, longer time on ART, being 25 or less years old and low CD4+ cell count and anaemia at delivery, as well as initiating ART on stavudine-containing or abacavir-containing regimen. There was no difference postpartum loss to follow-up rates between the incident pregnancies group (hazard ratio 0.9, 95% CI: 0.7–1.1) and those who initiated ART in pregnancy. Conclusion: The risk of virologic failure remains high among postpartum women, particularly those who conceive on ART. The results highlight the need to provide adequate support for HIV-positive women with fertility intention after ART initiation and to strengthen monitoring and retention efforts for postpartum women to sustain the benefits of ART.

The detection of early failures in electromigration (EM) and the complicated statistical nature of this important reliability phenomenon have been difficult issues to treat in the past. A satisfactory experimental approach for the detection and the statistical analysis of early failures has not yet been established. This is mainly due to the rare occurrence of early failures and difficulties in testing of large sample populations. Furthermore, experimental data on the EM behavior as a function of varying number of failure links are scarce. In this study, a technique utilizing large interconnect arrays in conjunction with the well-known Wheatstone Bridge is presented. Three types of structures with a varying number of Ti/TiN/Al(Cu)/TiN-based interconnects were used, starting from a small unit of five lines in parallel. A serial arrangement of this unit enabled testing of interconnect arrays encompassing 480 possible failure links. In addition, a Wheatstone Bridge-type wiring using four large arrays in each device enabled simultaneous testing of 1920 interconnects. In conjunction with a statistical deconvolution to the single interconnect level, the results indicate that the electromigration failure mechanism studied here follows perfect lognormal behavior down to the four sigma level. The statistical deconvolution procedure is described in detail. Over a temperature range from 155 to 200 °C, a total of more than 75 000 interconnects were tested. None of the samples have shown an indication of early, or alternate, failure mechanisms. The activation energy of the EM mechanism studied here, namely the Cu incubation time, was determined to be Q=1.08±0.05 eV. We surmise that interface diffusion of Cu along the Al(Cu) sidewalls and along the top and bottom refractory layers, coupled with grain boundary diffusion within the interconnects, constitutes the Cu incubation mechanism.

To determine the prevalence and explore predictors of Complementary and Alternative Medicine (CAM) use during early pregnancy. A questionnaire survey of pregnant women (500) attending for mid trimester scan at the maternity services in Grampian, North-East Scotland. Outcome measures included; CAM used; vitamins and minerals used; independent predictors of use; views and experiences. Descriptive and inferential statistical analysis. The response rate was 66%. Two thirds of respondents (63%) reported using CAM, excluding vitamins and minerals, during early pregnancy. Respondents reported using a total of 28 different CAM modalities, of which oral herbal products were the most common (37% of respondents, 25 different products). The independent predictors of CAM use identified were: use by family and friends (OR 4.1, 95% CI 2.3-7.3, p<0.001); ethnicity (non-white British) (OR 3.4, 95% CI 1.8-6.8, p<0.001); and use prior to pregnancy (OR 2.4, 95% CI 1.2-4.8, p=0.014). In comparison to prescribed medicines, most users were uncertain if CAM were safer (63%), more effective (66%), free from possible adverse effects (46%) or drug-CAM interactions (50%). Despite the majority of respondents being uncertain about their safety and effectiveness, CAM modalities and CAM products are widely used during the early stages of pregnancy in this study population. The role of family and friends rather than health professionals in the decision to use CAM may be of concern and requires further investigation. Copyright © 2014 Elsevier Ireland Ltd.

Medical abortion in early pregnancy: experience in China.

PubMed

Cheng, Linan

2006-07-01

When medical abortion was first introduced in China, prostaglandins (PGs) were used alone or in combination with Chinese herbs or steroid drugs, but the results were not satisfactory. Mifepristone is now produced in three companies in China and is commonly used with PGs for medical abortion. We performed a Chinese- and English-language literature review of medical abortion in early pregnancy in China. A large multicenter trial conducted in China showed that, when used with a PGF(2alpha) analogue, the complete abortion rate in women given multiple doses of mifepristone (total, 150 mg) was significantly higher than that in women given a single dose of 200 mg of mifepristone. Oral misoprostol (0.6 mg) with mifepristone is now the most commonly used regimen, with a complete abortion rate of over 93%. In China, medical abortion is currently restricted to pregnancies before 49 days, but some hospitals have recently extended the use of medical abortion to pregnancies beyond 49 days. Prolonged bleeding is the main medical abortion side effect and is more likely to occur if the blood levels of human chorionic gonadotrophin fall slowly or when the gestational sac is big. Prescription of testosterone propionate may reduce the duration of bleeding. Over 80% of Chinese women are satisfied with current medical abortion regimens and will choose medical abortion again if they need to terminate a future unwanted pregnancy. Currently, medical abortion is a safe, efficient and acceptable method for the termination of early pregnancy in China.

Options in making use of pregnancy history in planning and analysing studies of reproductive failure.

PubMed

Olsen, J

1994-04-01

Although more epidemiological studies of reproductive health have been published recently, important scientific achievements remain few. Among the reasons for this are existing methodological constraints. Fertility is low in most parts of the industralized world, making the observation time short. Pregnancy itself is under extremely close medical surveillance with intensive health care interventions such as prenatal screening, induced abortions, induced labour, and prescribed changes in environmental exposures, but the epidemiologists are generally left with cause-effect experiences which escaped medical attention or study of diseases for which there is no cure. The main problem in non-experimental research of reproductive failure, however, is the most pregnancies are planned and past pregnancy experience is used in the planning. Self selection into different exposure categories according to past pregnancy experience should therefore be considered when studies are designed and analysed. To consider how to deal with past pregnancy experience as an indicator "background" risk of reproductive failure. The present standard is to take parity or gravidity into consideration but this may be of little value and could even be very misleading. No simple and universal analytic strategy is available in reproductive epidemiology. On some occasions studies should be restricted to the first pregnancy only, in other situations the past reproductive experience may be used to form groups that are comparable in terms of pre-exposure risk.

We investigated whether changes in cellular immunity and oxidative stress in pregnancy have any association with spontaneous miscarriage. Circulating adenosine deaminase (ADA) activity as a marker of cellular immunity and malondialdehyde (MDA) and catalase (CAT), glutathione peroxidase (GPx) as markers of T lymphocyte activation and parameters of oxidative stress and antioxidant defense were compared between 40 women with early pregnancy loss and another 40 women with ungoing healthy pregnancy. Women with miscarriage had higher serum ADA and GPx levels when compared with women with normal pregnancy (p = 0.034 and p < 0.001, respectively). Although serum MDA level was slightly higher in women with miscarriage, the difference was not significant (p = 0.083). CAT levels were alike in both groups. We have demonstrated an increased cellular immunity and perhaps a compensated oxidative stress related to increased antioxidant activation in women with early spontaneous pregnancy loss.

Context Maternal pre-pregnancy obesity may increase the risk of childhood obesity but it is unknown whether other metabolic factors in early pregnancy such as lipid profile and hypertension are associated with offspring cardiometabolic traits. Objective Our objective was to investigate whether fasting lipid, glucose, and insulin levels during early pregnancy and maternal pre-pregnancy weight status, are associated with offspring adiposity measures, lipid levels and blood pressure at preschool age. Design and Methods The study included 618 mother-child pairs of the pregnancy cohort “Rhea” study in Crete, Greece. Pregnant women were recruited at the first prenatal visit (mean: 12weeks, SD: 0.7). A subset of 348 women provided fasting serum samples for glucose and lipid measurements. Outcomes measures were body mass index, abdominal circumference, sum of skinfold thickness, and blood pressure measurements at 4 years of age. A subsample of 525 children provided non-fasting blood samples for lipid measurements. Results Pre-pregnancy overweight/obesity was associated with greater risk of offspring overweight/obesity (RR: 1.83, 95%CI: 1.19, 2.81), central adiposity (RR: 1.97, 95%CI: 1.11, 3.49), and greater fat mass by 5.10mm (95%CI: 2.49, 7.71) at 4 years of age. These associations were more pronounced in girls. An increase of 40mg/dl in fasting serum cholesterol levels in early pregnancy was associated with greater skinfold thickness by 3.30mm (95%CI: 1.41, 5.20) at 4 years of age after adjusting for pre-pregnancy BMI and several other confounders. An increase of 10mmHg in diastolic blood pressure in early pregnancy was associated with increased risk of offspring overweight/obesity (RR: 1.22, 95%CI: 1.03, 1.45), and greater skinfold thickness by 1.71mm (95% CI: 0.57, 2.86) at 4 years of age. Conclusions Metabolic dysregulation in early pregnancy may increase the risk of obesity at preschool age. PMID:25970502

Does early reading failure decrease children's reading motivation?

2008-01-01

The authors used a pretest-posttest control group design with random assignment to evaluate whether early reading failure decreases children's motivation to practice reading. First, they investigated whether 60 first-grade children would report substantially different levels of interest in reading as a function of their relative success or failure in learning to read. Second, they evaluated whether increasing the word reading ability of 15 at-risk children would lead to gains in their motivation to read. Multivariate analyses of variance suggest marked differences in both motivation and reading practice between skilled and unskilled readers. However, bolstering at-risk children's word reading ability did not yield evidence of a causal relationship between early reading failure and decreased motivation to engage in reading activities. Instead, hierarchical regression analyses indicate a covarying relationship among early reading failure, poor motivation, and avoidance of reading.

To determine anxiety levels of women presenting to an early pregnancy assessment unit (EPAU) with abdominal pain and/or vaginal bleeding and to assess how these levels change over time and according to ultrasonographic diagnosis. We undertook a prospective cohort study in an EPAU in a large UK teaching hospital. Women with abdominal pain and/or vaginal bleeding in early pregnancy (< 12 weeks' gestation) presenting for the first time were eligible for inclusion in the study. State anxiety levels were assessed using the standardized short form of Spielberger's state-trait anxiety inventory (STAI) on three occasions (before, immediately after and 48-72 hours after an ultrasound scan). Scores were correlated with ultrasonographic diagnosis. The diagnosis was either certain or uncertain. Certain diagnoses were either positive, i.e. a viable intrauterine pregnancy (IUP), or negative, i.e. a non-viable IUP or ectopic pregnancy. Uncertain diagnoses included pregnancy of unknown location and pregnancy of uncertain viability. Statistical analysis involved mixed ANOVAs and the post-hoc Tukey-Kramer test. A total of 160 women were included in the study. Anxiety levels decreased over time for women with a certain diagnosis (n = 128), even when negative (n = 64), and increased over time for women with an uncertain diagnosis (n = 32). Before the ultrasound examination, anxiety levels were high (STAI value, 21.96 ± 1.11) and there was no significant difference between the five groups. Immediately after the ultrasound examination, anxiety levels were lower in the viable IUP group (n = 64; 7.75 ± 1.13) than in any other group. The difference between the five groups was significant (P < 0.005). After 48-72 hours, women with a certain diagnosis had significantly lower anxiety levels than had those with an uncertain diagnosis (10.77 ± 4.30 vs 22.94 ± 1.65; P < 0.005). The experience of abdominal pain and/or vaginal bleeding in early pregnancy is highly anxiogenic. Following an

Recent studies have shown high prevalence rates for pelvic girdle pain (PGP) in pregnancy. Some risk factors for developing PGP have been suggested, but the evidence is weak. Furthermore there is almost no data on how findings from clinical examinations are related to subsequent PGP. The main purpose for this study was to study the associations between socio-demographical, psychological and clinical factors measured at inclusion in early pregnancy and disability or pain intensity in gestation week 30. This is a prospective cohort study following women from early to late pregnancy. Eligible women were recruited at their first attendance at the maternity care unit. 268 pregnant women answered questionnaires and underwent clinical examinations in early pregnancy and in gestation week 30. We used scores on disability and pain intensity in gestation week 30 as outcome measures to capture the affliction level of PGP. Multiple linear regression analysis was used to study the associations between potential risk factors measured in early pregnancy and disability or pain intensity in gestation week 30. Self-reported pain locations in the pelvis, positive posterior pelvic pain provocation (P4) test and a sum of pain provocation tests in early pregnancy were significantly associated with disability and pain intensity in gestation week 30 in a multivariable statistic model. In addition, distress was significantly associated with disability. The functional active straight leg raise (ASLR) test, fear avoidance beliefs and the number of pain sites were not significantly associated with either disability or pain intensity. The results suggest that a clinical examination, including a few tests, performed in early pregnancy may identify women at risk of a more severe PGP late in pregnancy. The identification of clinical risk factors may provide a foundation for development of targeted prevention strategies.

Contraceptive failure after hysteroscopic sterilization: Analysis of clinical and demographic data from 103 unplanned pregnancies

Objective This investigation examined data on unplanned pregnancies following hysteroscopic sterilization (HS). Methods A confidential questionnaire was used to collect data from women with medically confirmed pregnancy (n=103) registered after undergoing HS. Results Mean (±SD) patient age and body mass index (BMI) were 29.5±4.6 years and 27.7±6.1 kg/m2, respectively. Peak pregnancy incidence was reported at 10 months after HS, although <3% of unplanned pregnancies occurred within the first three months following HS. Mean (±SD) interval between HS and pregnancy was 19.6±14.9 (range, 2 to 84) months. Patients age ≥30 years and BMI <25 reported conception after HS somewhat sooner than younger patients, although the differences in time to pregnancy were not significant (P=0.24 and 0.09, respectively). The recommended post-HS hysterosalpingogram (to confirm proper placement and bilateral tubal occlusion) was obtained by 66% (68/103) of respondents. Conclusion This report is the first to provide patient-derived data on contraceptive failures after HS. While adherence to backup contraception 3 months after HS can be poor, many unintended pregnancies with HS occur long after the interval when alternate contraceptive is required. Many patients who obtain HS appear to ignore the manufacturer's guidance regarding the post-procedure hysterosalpingogram to confirm proper device placement, although limited insurance coverage likely contributes to this problem. The greatest number of unplanned pregnancies occurred 10 months after HS, but some unplanned pregnancies were reported up to 7 years later. Age, BMI, or surgical history are unlikely to predict contraceptive failure with HS. Further follow-up studies are planned to capture additional data on this issue. PMID:26623413

Approximately 80% of cheetahs living in typical zoological collections never reproduce. In more than 60% of breedings, the female is confirmed to ovulate, but parturition fails to occur. It is unknown if these non-pregnant intervals of elevated progesterone (deemed luteal phases) are conception failures or a pregnancy terminating in embryonic/fetal loss. There have been recent advances in metabolic profiling and proteome analyses in many species with mass spectrometry used to identify 'biomarkers' and mechanisms indicative of specific physiological states (including pregnancy). Here, we hypothesized that protein expression in voided cheetah feces varied depending on pregnancy status. We: 1) identified the expansive protein profile present in fecal material of females; and 2) isolated proteins that may be candidates playing a role in early pregnancy establishment and diagnosis. Five hundred and seventy unique proteins were discovered among samples from pregnant (n = 8), non-pregnant, luteal phase (n = 5), and non-ovulatory control (n = 5) cheetahs. Four protein candidates were isolated that were significantly up-regulated and two were down-regulated in samples from pregnant compared to non-pregnant or control counterparts. One up-regulated candidate, immunoglobulin J chain (IGJ; an important component of the secretory immune system) was detected using a commercially available antibody via immunoblotting. Findings revealed that increased IGJ abundance could be used to detect pregnancy successfully in >80% of 23 assessed females within 4 weeks after mating. The discovery of a novel fecal pregnancy marker improves the ability to determine reproductive, especially gestational, status in cheetahs managed in an ex situ insurance and source population.

Background. Miscarriage is a very common complication during early pregnancy. So far, clinical therapies have limitation in preventing the early pregnancy loss. Chinese Medicine, regarded as gentle, effective, and safe, has become popular and common as a complementary and alternative treatment for miscarriages. However, the evidence to support its therapeutic efficacy and safety is still very limited. Objectives and Methods. To summarize the clinical application of Chinese Medicine for pregnancy and provide scientific evidence on the efficacy and safety of Chinese medicines for miscarriage, we located all the relevant pieces of literature on the clinical applications of Chinese Medicine for miscarriage and worked out this systematic review. Results. 339,792 pieces of literature were identified, but no placebo was included and only few studies were selected for systematic review and conducted for meta-analysis. A combination of Chinese medicines and Western medicines was more effective than Chinese medicines alone. No specific safety problem was reported, but potential adverse events by certain medicines were identified. Conclusions. Studies vary considerably in design, interventions, and outcome measures; therefore conclusive results remain elusive. Large scales of randomized controlled trials and more scientific evidences are still necessary to confirm the efficacy and safety of Chinese medicines during early pregnancy. PMID:24648851

Antithyroid Drug Side Effects in the Population and in Pregnancy.

Methimazole (MMI) and propylthiouracil (PTU) are both associated with birth defects and may also rarely be associated with agranulocytosis and liver failure. The frequency of these side effects when antithyroid drugs (ATDs) are used in the population in general or in pregnancy remains to be elucidated. All individuals registered as the parent of a live-born child in Denmark, 1973–2008, were identified (n = 2 299 952) and studied from 1995 through 2010 for the use of ATDs. Outcomes were agranulocytosis, liver failure, and birth defects in their offspring. To evaluate the frequency of these side effects associated with the use of ATDs in pregnancy, all live-born pregnancies (n = 830 680), 1996–2008, were identified in a subanalysis. In the population studied, 28 998 individuals redeemed prescriptions of ATDs (exposure in 2115 pregnancies), which was associated with 45 cases of agranulocytosis (one in pregnancy) and 10 cases of liver failure (one in pregnancy). This corresponded to 41 and 11 cases of agranulocytosis and liver failure per 5 million inhabitants during a 10-year period (agranulocytosis: 0.16% of ATDs exposed [MMI: 0.11% vs PTU: 0.27%, P = .02]; liver failure: 0.03% of ATDs exposed [MMI: 0.03% vs PTU: 0.05%, P = .4]). The majority (83%) developed the side effect within 3 months of ATD treatment and 25% during hyperthyroidism relapse. The use of ATDs in pregnancy was associated with birth defects in 3.4% of exposed children (44 cases per 5 million inhabitants per 10 y), and the frequency of birth defects after ATD exposure was 75 times higher than both maternal agranulocytosis and liver failure in pregnancy. In the Danish population in general, ATDs associated birth defects and agranulocytosis had similar frequencies and were more common than liver failure, whereas for the use of ATDs in pregnancy, birth defects were dominant. The burden of side effects to the use of ATDs can be reduced by restricting the use of ATDs in early pregnancy.

To estimate the proportion of women in early pregnancy prescribed potentially feto-toxic medications at an out-patient clinic in Malawi. Over six-months the number of women of child-bearing age attending out-patient clinics and prescribed medicines at Mitundu Community Hospital was derived from the hospital's registry and pharmacy records. Women prescribed potentially feto-toxic medicines (using Food and Drug Administration classifications) by medical assessments were subsequently interviewed and pregnancy tested. Exposure to potentially feto-toxic medications was estimated and differences between pregnant and non-pregnant women were described. Of 8970 female outpatients, 1012 (11.3%; 95% CI: 10.6% to 12%) were prescribed potentially feto-toxic medicines. After excluding 740 as unlikely to be pregnant, 209 women had negative pregnancy tests and 63 were confirmed as pregnant, representing one in 16 of women prescribed contraindicated medicines or between 2.8% and 3.5% of all women attending in early pregnancy. Most medicines were FDA rated C or D. Only 152 (55.9%) of these women had been asked about pregnancy and prescribing practices did not discriminate between pregnant and non-pregnant patients. Assessment and prescribing practices for women attending out-patient clinics who might be in early pregnancy were inadequate, increasing the risk of exposure to potentially feto-toxic medicines.

Nausea and vomiting are troublesome symptoms occurring in the first trimester of pregnancy. The aim of this study was to describe the impact these symptoms have on women in early pregnancy by interviewing, using a structured questionnaire, 593 pregnant women presenting with nausea and vomiting in the first trimester of pregnancy. The women were asked to complete the Rhodes index of nausea and vomiting and the MOS 36 Short Form Health Survey (SF-36). Symptoms of nausea and vomiting started early in pregnancy. Nausea was the most troublesome symptom experienced by women, both in its duration and intensity. Low scores for the SF-36 were found for all items, particularly physical functioning, energy and social functioning. The women described substantial effects on working, household duties and parenting activities. Findings from this study suggest nausea and vomiting in early pregnancy has a profound impact on women's general sense of well-being and day to day life activities.

Previous reports have shown that reproductive tract score (RTS) can predict reproduction outcomes in seasonally bred beef heifers, although the accuracy can vary. Some ultrasonographic measures of the female reproductive tract and pelvis area have also been associated with reproductive outcome in young heifers. The objectives of this study were to determine which transrectal ultrasound or pelvis measures taken at a single examination are independent predictors of reproductive failure and whether the RTS system can be optimized with this information. In this observational study, year-old beef heifers (n = 488) in 2 birth cohorts were followed from just before the first breeding until confirmation of pregnancy. A single pre-breeding examination included body condition score, RTS, ultrasound measures of the reproductive tract (length and diameter of the left and right ovaries, presence and diameter of a CL, largest follicle diameter and left uterus horn diameter) and transverse and vertical diameters of the pelvis. Additional farm records including dam parity, sire, birth weight and birth date, weaning weight, weaning date, prebreeding body weight, AI dates, and semen used were available. Breeding consisted of 50 days of AI, followed 5 to 7 days later by a 42-day bull breeding period. Pregnancy failure was defined as the failure to become pregnant after the AI and bull breeding periods, while anestrus was defined as the failure to be detected in estrus during the 50-day AI period. From the prebreeding data and farm records, independent predictors of pregnancy failure and anestrus were identified using stepwise reduction in multiple logistic regression models. Age at the onset of breeding was the only consistent independent predictor of pregnancy failure and anestrus in both cohorts of this study (P < 0.05). Body condition score, uterus horn diameter, absence of a CL, largest follicle of less than 13 mm, and pelvis area (PA) were the prebreeding examination variables

Sterilization failures in Singapore: an examination of ligation techniques and failure rates.

1977-04-01

The University Department of Obstetrics and Gynecology, Kandang Kerbau Hospital in Singapore, initiated a study in early 1974 of failure rates for various methods of sterilization and the factors responsible for the failures. During the period January 1974 to March 1976, 51 cases of first pregnancy following ligation were discovered. Cumulative failure rates at 24 months were 0.34 per 100 women for abdominal sterilization, 1.67 for culdoscopic, 3.12 for vaginal, and 4.49 for laparoscopic procedures. Findings for 35 patients who underwent religation showed that recanalization and the establishment of a fistulous opening caused the majority of failures. Clearly, more effective methods of tubal occlusion in sterilization are needed.

There are few reports on pregnancies in sporadic and familial amyotrophic lateral sclerosis (ALS). We report on a young woman with sporadic ALS who gave birth twice during the course of her disease. The first pregnancy occurred 13 months after the onset of symptoms, and one month after diagnosis. The pregnancy was uncomplicated and resulted in vaginal delivery of a healthy boy. Fifteen months later, when she was already bed-ridden, she became pregnant again. She received a percutaneous endoscopic gastrostomy in the 21st gestational week and underwent early Caesarean section in the 34th week of gestation. The child was ventilated for 72 h in a neonatological unit. The patient was tracheotomized and ventilated two months later, i.e. 47 months after symptom onset, and died nine months later from gastrointestinal haemorrhage. Her two children have developed without abnormalities to date. This case confirms that pregnancies in early-stage ALS can develop normally and may result in uncomplicated vaginal delivery. Pregnancies in late stages may be critical for mother and child, and early delivery by Caesarean section may become necessary although neonatal outcome can be good.

Plasma volume expansion has been associated with fetal growth. Our objective was to examine the associations between maternal nutritional status in early pregnancy and extracellular water (ECW), total body water (TBW), and percentage plasma volume change across pregnancy. In a subsample of 377 pregnant women participating in a cluster-randomized trial of micronutrient supplementation, hemoglobin, hematocrit, and multi-frequency bioelectrical impedance were measured at ~10, 20, and 32 wk of gestation. In early pregnancy, women were short (mean ± SD, 148.9 ± 5.3 cm) and thin (19.5 ± 2.5 kg/m(2)). In mixed-effects multiple regression models, a 1-unit higher BMI at ~10 wk was associated with higher ECW and TBW (0.27 and 0.66 kg per kg/m(2), respectively; P < 0.01) at ~10, ~20, and ~32 wk. Height was also positively associated with ECW and TBW at each time point. Early pregnancy BMI was negatively associated with gains in ECW and TBW (-0.06 and -0.14 kg per kg/m(2), respectively; P < 0.01) from 10 to 20 wk, but not with 20- to 32-wk gains after accounting for weight gain. BMI was positively associated with percentage changes in plasma volume from 20 to 32 wk (0.57% per kg/m(2); P < 0.05). Height was not associated with changes in body water or plasma volume. Women with low BMI and height in early pregnancy have lower ECW and TBW in early, mid, and late pregnancy and lower late pregnancy plasma volume expansion, potentially increasing risk of fetal growth restriction.

Female sexual function is negatively influenced by pregnancy due to the physical and emotional changes. Although the most significant effect is seen in the third trimester of pregnancy, a considerable decrease in the frequency of intercourse and sexual desire in the first trimester has also been shown. To investigate the factors that affect sexuality in early pregnancy and the impact of awareness of pregnancy on female sexual function in the first trimester of pregnancy using two self-reported questionnaires. In this cross-sectional study, 130 healthy, married pregnant women who were admitted to the gynecology clinic between the 4th and 10th week of gestation were asked to complete a self-administered questionnaire and the female sexual function index (FSFI). The factors associated with FSFI score and monthly sexual activity frequency in the first trimester, as well as the differences in sexual activity frequency and FSFI scores between the women who were previously aware of their pregnancy and those who were yet unaware of their pregnancy. Women who were unaware of their pregnancy had significantly higher coitus frequency in comparison with the aware group (P = 0.002). Total FSFI score was 21.99 ± 8.13 in the aware group and 24.66 ± 3.76 in the unaware group (P = 0.02). None of the obstetric and sociodemographic variables had an influence on desire and pain scores. Arousal, lubrication, and satisfaction scores were adversely affected by awareness of pregnancy. Orgasm scores were influenced negatively by awareness and positively by love marriage; however, in multivariate linear regression analysis none of these were defined as independent factor for orgasm scores. Overall FSFI scores and monthly frequency of sexual activity were only affected by awareness. The results of this study suggest that in early gestation, awareness of pregnancy is associated with lower female sexual function. Furthermore, obstetric and sociodemographic factors seem to be

To analyze the plasmatic ADM level in early pregnancy and to investigate the diagnostic value of ADM in early ectopic pregnancy (EP). 70 patients with EP who had menopause for 5~8 weeks were included as study group, while 155 women with normal intrauterine pregnancy were also included as control group. The correlation between ADM level and menopause weeks was statistically analyzed and ROC curve was used to identify the diagnostic value of ADM. (1) In 155 cases of normal intrauterine pregnancy, the plasmatic ADM level was increased with menopause weeks in linear relationship, and the correlation coefficient (R) was 0.991 (P<0.05). In 70 patients with EP, no significant increase was found with menopause weeks and no linear relationship can be found between ADM level and menopause weeks in EP group. The correlation coefficient (R) was 0.744 (P>0.05). (2) The multiple of median of plasmatic ADM level in EP group of menopause for 8 weeks was obviously lower than the intrauterine control group (P<0.01). (3) ROC curve was used to analyze the cut-off value of ADM level in the diagnosis of EP, and the area under the ROC curve was 0.523 (P>0.05) regardless of menopause weeks, however, the area under the ROC curve was 0.702 (P<0.05) at 8 weeks after menopause with sensitivity of 53.50% and specificity of 85.00%. Different from normal intrauterine pregnancy, plasmatic ADM level in early EP was relatively lower and no significant increase was found with menopause weeks; further studies are still needed for plasmatic ADM level as an indicator in the early diagnosis of EP.

Early pregnancy failure (EPF) is a common complication of pregnancy. Surgical intervention carries a risk of complications and, therefore, medical treatment appears to be a safe alternative. Unfortunately, the current medical treatment with misoprostol alone has complete evacuation rates between 53% and 87%. Some reports suggest that sequential treatment with mifepristone and misoprostol leads to higher success rates than misoprostol alone. To evaluate the added value of mifepristone to current non-surgical treatment regimens in women with EPF we performed a systematic literature search. Electronic databases were searched: PubMed, Cochrane Library, Current Controlled Trials, and ClinicalTrials.gov. Clinical studies, both randomised and non-randomised trials, reporting on the added value of mifepristone to current non-surgical treatment regimens in women with EPF were included. Data of sixteen studies were extracted using a data extraction sheet (based on the Cochrane Consumers and Communication Review Group's data extraction template). The methodological quality was assessed using the Cochrane Collaboration Risk of Bias tool. In five randomised and eleven non-randomised trials, success rates of sequential treatment with mifepristone and misoprostol in case of EPF varied between 52% and 95%. Large heterogeneity existed in treatment regimens and comparators between studies. The existing evidence is insufficient to draw firm conclusions about the added value of mifepristone to misoprostol alone. A sufficiently powered randomised, double blinded placebo-controlled trial is urgently required to test whether, in EPF, the sequential combination of mifepristone with misoprostol is superior to misoprostol only.

Early pregnancy in the mare: old concepts revisited.

PubMed

Klein, C

2016-07-01

"Maternal recognition of pregnancy" (MRP) is commonly used to describe the ongoing embryo-maternal communication during early pregnancy that culminates in prevention of luteolysis and ensures ongoing progestin support. The conceptus-derived pregnancy recognition signal has not yet been identified in the mare. Although equine conceptuses produce substantial amounts of estrogens, there is a lack of evidence that estrogens are the pregnancy recognition signal in mares. Conceptus mobility is integral to MRP and is driven by conceptus-derived prostaglandin production. Cessation of conceptus mobility, referred to as fixation, is caused by increases in conceptus size and uterine tone and reduction in sialic acid content of the embryonic capsule. Gene expression profiling of equine preimplantation conceptuses revealed expression of neuraminidase 2 (NEU2), an enzyme that cleaves sialic acid from polysaccharide chains. Furthermore, secretion of NEU2 by conceptuses in vitro was functionally active; it appears therefore, that the conceptus itself regulates sialic acid content through expression of NEU2. Based on gene expression profiling, equine conceptuses express increasing amounts of fibrinogen during early development. Western blot analysis confirmed secretion of fibrinogen into culture medium when conceptuses were cultured in vitro and with immunohistochemistry, the acellular glycoprotein capsule of the conceptus had particularly intense staining for fibrinogen. Therefore, we hypothesize that conceptus-derived fibrinogen interacts with endometrial integrins to promote cessation of conceptus mobility and fixation. Indeed, next generation sequencing analysis of conceptus and endometrial samples 16 d after ovulation revealed that the integrin signaling pathway is significantly enriched in both sample types. Real-time reverse transcription polymerase chain reaction (RT-PCR) confirmed ITGAVB1 as the most abundant integrin receptor in endometrium; fibrinogen has the highest

To evaluate the associations between first trimester 25-hydroxyvitamin D [25(OH)D] status and changes in high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), total cholesterol (TC), triglyceride (TG) concentrations, TG/HDL-c, and TC/HDL-c ratios throughout pregnancy. We hypothesized that first trimester 25(OH)D inadequacy is associated with lower concentrations of HDL-c and higher LDL-c, TC, TG, TG/HDL-c, and TC/HDL-c ratios throughout pregnancy. A prospective cohort study with 3 visits at 5-13 (baseline), 20-26, and 30-36 gestational weeks, recruited 194 pregnant women attending a public health care center in Rio de Janeiro, Brazil. Plasma 25(OH)D concentrations were measured in the first trimester using liquid chromatography-tandem mass spectrometry. 25(OH)D concentrations were classified as adequate (≥75nmol/L) or inadequate (<75nmol/L). Serum TC, HDL-c, and TG concentrations were measured enzymatically. Crude and adjusted longitudinal linear mixed-effects models were employed to evaluate the association between the first trimester 25(OH)D status and changes in serum lipid concentrations throughout pregnancy. Confounders adjusted for in the multiple analysis were age, homeostatic model assessment (HOMA), early pregnancy BMI, leisure time physical activity before pregnancy, energy intake, and gestational age. At baseline, 69% of the women had inadequate concentrations of 25(OH)D. Women with 25(OH)D inadequacy had higher mean LDL-c than those with adequate concentrations (91.3 vs. 97.5mg/dL; P=0.064) at baseline. TC, HDL-c, LDL-c TG, TG/HDL-c ratios, and TC/HDL-c ratios, increased throughout pregnancy independently of 25(OH)D concentrations (ANOVA for repeated measures P<0.001). The adjusted models showed direct associations between the first trimester 25(OH)D status and changes in TC (β=9.53; 95%CI=1.12-17.94), LDL-c (β=9.99; 95% CI=3.62-16.36) concentrations, and TC/HDL-c ratios (β=0.16; 95% CI=0.01-0.31) throughout

Cardiometabolic (CM) risk factors are linked to increased morbidity. Disturbed sleep is associated with CM risk factors in late pregnancy, but little is known about sleep in early pregnancy and CM risk factors. Diary and actigraphy-assessed sleep information, as well as CM outcomes (blood pressure (BP) and body mass index (BMI)), were collected thrice from pregnant women (N=161) in early pregnancy: T1 (10-12 weeks), T2 (14-16 weeks) and T3 (18-20 weeks). The sleep variables evaluated included sleep onset latency (SOL), wake after sleep onset (WASO) and total sleep time (TST). Sleep variables were dichotomised using established clinical cut-offs. BMI and BP significantly changed across time. Women with persistent SOL≥20 min had greater BMI than women without persistent SOL≥20 min prior to covariate adjustment at T1 and T2, but at T3 the BMI values converged. Similar results were observed for persistent WASO≥30 min. Persistently long WASO, as measured by actigraphy, was associated with elevated SBP, after controlling for covariates. Consistent with anecdotal evidence, it appears as if a subset of women report substantial difficulty initiating and maintaining sleep during early pregnancy and this may augment the risk of higher BP and BMI. Understanding these relationships is important as CM risk factors are linked to maternal and infant morbidity. Assessing sleep in early pregnancy may bestow time necessary for appropriate intervention. Copyright © 2014 Elsevier B.V. All rights reserved.

Malignancy during pregnancy has become a significant cause of maternal death in developed countries, likely due to both an older pregnant population, and increases of cervical cancer in younger women. Our aim is to investigate the clinical aspects of malignancy during pregnancy in Japan and to use this information to identify opportunities for earlier detection and treatment. We provided a questionnaire to 1508 secondary or tertiary care hospitals in Japan. We reviewed the clinical characteristics of cases with malignancy during pregnancy for the period of January to December, 2008. From the 760 institutions which responded, we obtained clinical information for 227 unique cases. The questionnaire provided clinical information, including disease site, pregnancy outcome and how the disease was detected. The most common type of malignancy was cervical cancer (n = 162, 71.4%) followed by ovarian (n = 16, 7.0%) and breast cancer (n = 15, 6.6%). Leukemia (n = 7, 3.1%), colon cancer (n = 5, 2.2%), gastric cancer (n = 5, 2.2%), malignant lymphoma (n = 4, 1.8%), thyroid cancer (n = 3, 1.3%), brain cancer (n = 3, 1.3%), endometrial cancer (n = 2, 0.9%), and head and neck cancer (n = 2, 0.9%) accounted for the remaining cases. Overall, gynecological malignancies accounted for 79.3% (95% confidence interval 74.0-84.6) of pregnancy associated malignancies diagnosed in the present study. The majority of cervical cancers, 149 (92.0%) of 162, were diagnosed by a Pap (Papanicolaou) smear during early gestation. Ten (62.5%) of the ovarian cancer cases were diagnosed by ultrasonography during a prenatal checkup or at the time of initial pregnancy diagnosis. Out of 14 breast cancers, only one (7.1%) was diagnosed by screening breast exam. From this study, we reaffirm the clear and significant benefits of prenatal checkups starting at an early gestational age for the detection of gynecological cancers during pregnancy. Conversely, breast

Low vitamin D status in pregnancy was proposed as a risk factor of preeclampsia. We assessed the effect of vitamin D supplementation (4,400 vs. 400 IU/day), initiated early in pregnancy (10-18 weeks), on the development of preeclampsia. The effects of serum vitamin D (25-hydroxyvitamin D [25OHD]) levels on preeclampsia incidence at trial entry and in the third trimester (32-38 weeks) were studied. We also conducted a nested case-control study of 157 women to investigate peripheral blood vitamin D-associated gene expression profiles at 10 to 18 weeks in 47 participants who developed preeclampsia. Of 881 women randomized, outcome data were available for 816, with 67 (8.2%) developing preeclampsia. There was no significant difference between treatment (N = 408) or control (N = 408) groups in the incidence of preeclampsia (8.08% vs. 8.33%, respectively; relative risk: 0.97; 95% CI, 0.61-1.53). However, in a cohort analysis and after adjustment for confounders, a significant effect of sufficient vitamin D status (25OHD ≥30 ng/ml) was observed in both early and late pregnancy compared with insufficient levels (25OHD <30 ng/ml) (adjusted odds ratio, 0.28; 95% CI, 0.10-0.96). Differential expression of 348 vitamin D-associated genes (158 upregulated) was found in peripheral blood of women who developed preeclampsia (FDR <0.05 in the Vitamin D Antenatal Asthma Reduction Trial [VDAART]; P < 0.05 in a replication cohort). Functional enrichment and network analyses of this vitamin D-associated gene set suggests several highly functional modules related to systematic inflammatory and immune responses, including some nodes with a high degree of connectivity. Vitamin D supplementation initiated in weeks 10-18 of pregnancy did not reduce preeclampsia incidence in the intention-to-treat paradigm. However, vitamin D levels of 30 ng/ml or higher at trial entry and in late pregnancy were associated with a lower risk of preeclampsia. Differentially expressed vitamin D

What is the Best Way to Reduce Unintended Pregnancies? A Micro Simulation of Contraceptive Switching, Discontinuation and Failure Patterns in France

Despite high rates of contraceptive use in France, over a third of pregnancies are unintended. We built a dynamic micro simulation model which applies data from the French COCON study on method switching, discontinuation, and failure rates to a hypothetical population of 20,000 women, followed for 5 years. We use the model to estimate the adjustment factor needed to make the survey data fit the demographic profile of France, by adjusting for underreporting of contraceptive non-use and abortions. We then test three behavior change scenarios which would aim to reduce unintended pregnancies: decreasing method failure, increasing time spent on effective methods, and increasing switching from less to more effective methods. Our model suggests that decreasing method failure is the most effective strategy for reducing unintended pregnancies, but all scenarios reduced unintended pregnancies by at least 25%. Dynamic micro simulations such as this may be useful for policy makers. PMID:25469928

Natural killer cells and regulatory T cells in early pregnancy loss

PubMed Central

SHARMA, SURENDRA

2015-01-01

Survival of the allogeneic embryo in the uterus depends on the maintenance of immune tolerance at the maternal-fetal interface. The pregnant uterus is replete with activated maternal immune cells. How this immune tolerance is acquired and maintained has been a topic of intense investigation. The key immune cells that predominantly populate the pregnant uterus are natural killer (NK) cells. In normal pregnancy, these cells are not killers, but rather provide a microenvironment that is pregnancy compatible and supports healthy placentation. In placental mammals, an array of highly orchestrated immune elements to support successful pregnancy outcome has been incorporated. This includes active cooperation between maternal immune cells, particularly NK cells, and trophoblast cells. This intricate process is required for placentation, immune regulation and to remodel the blood supply to the fetus. During the past decade, various types of maternal immune cells have been thought to be involved in cross-talk with trophoblasts and in programming immune tolerance. RegulatoryT cells (Tregs) have attracted a great deal of attention in promoting implantation and immune tolerance beyond implantation. However, what has not been fully addressed is how this immune-trophoblast axis breaks down during adverse pregnancy outcomes, particularly early pregnancy loss, and in response to unscheduled inflammation. Intense research efforts have begun to shed light on the roles of NK cells and Tregs in early pregnancy loss, although much remains to be unraveled in order to fully characterize the mechanisms underlying their detrimental activity. An increased understanding of host-environment interactions that lead to the cytotoxic phenotype of these otherwise pregnancy compatible maternal immune cells is important for prediction, prevention and treatment of pregnancy maladies, particularly recurrent pregnancy loss. In this review, we discuss relevant information from experimental and human

Teenage pregnancy has been well studied from a demographic risk perspective, but less data examining the early interpersonal family experiences of teenage mothers are available. We aimed to explore the relative impact of demographic, early interpersonal family relationships and depressive symptomatology as associations for teenage, as compared to non-teenage, childbearing. A prospective cross-sectional cohort study was undertaken. Institutional ethics committee approval and informed consent were obtained. Data from consecutive teenage (teenage) and non-teenage (control) subgroups of antenatal women were compared. Subjects were interviewed and completed the following questionnaires: demographic, drug use and lifestyle; early life experiences; Hospital Anxiety and Depression Scale (HADS); and General Health Questionnaire-28. In multivariate analysis, the following factors had a significant independent association with younger age of motherhood in order of magnitude: a history of parental separation/divorce in early childhood; exposure to family violence in early childhood; illicit drug use (ever or in pregnancy); idealization of the pregnancy; low family income; a positive HADS-A or HADS-D subscale score; and a low level of education. Interventions to reduce the rate of teenage births need to be multifocal and should include strategies to address early childhood exposure to parental separation and violence, reduce idealization of pregnancy, diagnose psychological symptomatology and offer alternative career choices to children defaulting in the education system.

To explore the gestational age of early-onset intrahepatic cholestasis (ICP) of pregnancy, and to analyze the relationship between the clinical biochemical indices and pregnancy outcomes in order to arrive at a reasonable diagnosis and administer appropriate treatment. This is a retrospective clinical study. We selected 47,260 pregnant women who received prenatal care and underwent childbirth at the International Peace Maternity and Child Health Hospital affiliated to Shanghai Jiao Tong University from January 2014 to December 2016 for participating in this study. Of these 47,260 women, 407 developed ICP. To calculate the gestational week cutoff between early- and late-onset ICP by the receiver-operating characteristic (ROC) curve and Youden's index. Two independent samples t tests and chi square test were used to compare the differences in biochemical indices and pregnancy outcomes between the two groups. We found that 34 weeks is the most appropriate cutoff gestational age for the diagnosis of early-onset ICP. Early-onset ICP is characterized by early onset, long disease duration and a higher incidence of preterm labor, fetal distress, and fetal low birth weight compared to late-onset ICP. Thirty-four weeks is the most appropriate cutoff gestational age for the diagnosis of early-onset ICP. And to reduce the adverse pregnancy outcomes in cases of early-onset ICP, we suggest prolonging gestation up to 37 weeks as far as possible before selecting iatrogenic birth.

Substantial epidemiological evidence documents diverse health benefits, including reduced risks of hypertension, associated with diets high in fiber. Few studies, however, have investigated the extent to which dietary fiber intake in early pregnancy is associated with reductions in preeclampsia risk. We assessed the relationship between maternal dietary fiber intake in early pregnancy and risk of preeclampsia. We also evaluated cross-sectional associations of maternal early pregnancy plasma lipid and lipoprotein concentrations with fiber intake. The study population comprised 1,538 pregnant Washington State residents. A 121-item food frequency questionnaire (FFQ) was used to assess maternal dietary intake, 3 months before and during early pregnancy; and generalized linear regression procedures were used to derive relative risk (RR) and 95% confidence intervals (CIs). Dietary total fiber intake was associated with reduced preeclampsia risk. After adjusting for confounders, the RR of preeclampsia for women in the highest (> or =21.2 g/day) vs. the lowest quartile (<11.9 g/day) was 0.28 (95% CI = 0.11-0.75). We observed associations of similar magnitude when the highest vs. the lowest quartiles of water-soluble fiber (RR = 0.30; 95% CI = 0.11-0.86) and insoluble fiber (RR = 0.35; 95% CI = 0.14-0.87) were evaluated. Mean triglyceride concentrations were lower (-11.9 mg/dl, P = 0.02) and high-density lipoprotein cholesterol concentrations were higher (+2.63 mg/dl, P = 0.09) for women in the highest quartile vs. those in the lowest quartile. These findings of reduced preeclampsia risk with higher total fiber intake corroborate an earlier report; and expand the literature by providing evidence, which suggests that dietary fiber may attenuate pregnancy-associated dyslipidemia, an important clinical characteristic of preeclampsia.

To identify key factors involved in modifying leisure time physical activity (LTPA) during early pregnancy. A prospective study was conducted of 1175 pregnant women who attended a scheduled visit at Virgen de las Nieves University Hospital, Granada, Spain, at 20-22 weeks of pregnancy. The Paffenbarger Physical Activity Questionnaire was used to collect data regarding participation in any LTPA or physical activity performed according to society recommendations during early pregnancy and in the year before pregnancy. A polytomous regression model was used to identify factors associated with LTPA. Approximately 20.0% of the women did not engage in any LTPA, and 68.0% did not achieve the recommendations for exercise, either before or during pregnancy. Desirable changes related to performing any LTPA or the society recommendations for LTPA during pregnancy were associated with university level of education (aOR, 3.64 [95% CI, 1.54-8.56] and aOR, 1.75 [95% CI, 0.67-4.57], respectively) and smoking cessation at pregnancy (aOR, 2.05 [95% CI, 0.97-4.35] and aOR, 4.83 [95% CI, 1.31-17.83], respectively). Few women achieved the minimum recommendations for exercise before or during pregnancy. Nevertheless, adoption of healthy lifestyle choices during pregnancy seemed to promote other healthy habits, such as participation in LTPA.

To investigate high-anxiety and depression in women and men from early pregnancy to 3-months postpartum, 260 Portuguese couples (N = 520) filled in the State-Anxiety Inventory (STAI-S) and the Edinburgh Post-Natal Depression Scale (EPDS) at the first, second, and third pregnancy trimesters, childbirth, and 3-months postpartum. Rates for high-anxiety (STAI-S ≥ 45) in women (13.1%; 12.2%; 18.2%; 18.6%; 4.7%) and men (10.1%; 8.0%, 7.8%; 8.5%; 4.4%) and for depression (EPDS ≥ 10) in women (20.0%, 19.6%, 17.4%, 17.6%; 11.1%) and men (11.3%; 6.6%; 5.5%; 7.5%; 7.2%) were high. Rates for depression were higher than rates for high-anxiety only in women during early pregnancy and the postpartum, but not at the third pregnancy trimester and childbirth. Rates for high-anxiety and depression were higher in women than in men during pregnancy/childbirth, but not at 3-months postpartum. Rates for high-anxiety but not rates for depression were higher during pregnancy/childbirth compared to 3-months postpartum and only in women. Considering that 15.9% of the parents-to-be were highly anxious and/or depressed during pregnancy-comparing to 9.3% at 3-months postpartum-particular attention should be drawn to both women's and men's mental health early in pregnancy.

The aim was to evaluate expression of genes involved in the biosynthesis of prostaglandins (PTG), Prostaglandin H Synthase-1 (PTGS1) and PTGS2, PGF synthase (PTGFS), and PGE synthase (PTGES), PGF receptor (PTGFR), PGE receptors (PTGER2 and PTGER4), prostaglandin transporter (SLCO2A1) and hydroxyprostaglandin dehydrogenase-15 (HPGD). Endometrial biopsies were obtained from mares on day of ovulation (d0, n=4), late diestrus (LD, n=4), early luteolysis (EL, n=4) and after luteolysis (AL, n=4) during the cycle. Stages of the cycle were confirmed by plasma progesterone concentrations measured daily and ultrasound examinations. Biopsies were also taken on days 14 (P14; n=4), 15 (P15, n=4), 18 (P18, n=4) and 22 (P22; n=4) of pregnancy. Relative mRNA expressions were quantified using real-time RT-PCR. A mixed model was fitted on the normalized data and least significant difference test (α=0.05) was employed. Expression of PTGS1 mRNA was low throughout the estrous cycle and early days of pregnancy, but upregulated on P18 and P22. PTGS2 expression was increased on EL, but it was suppressed by pregnancy on P15, P18, and P22. PTGFS expression was upregulated in both cyclic and pregnant mares compared to d0 and its level was the highest on LD. PTGFR expression was transiently increased on LD and EL and was suppressed during early pregnancy. Both PTGES and PTGER2 expressions were increased on LD, EL, and early pregnancy, but were decreased after the luteolysis in cyclic mares as they remained high on P18 and P22. PTGER4 expression did not change throughout the cycle and early pregnancy. Levels of HPGD and SLCO2A1 were significantly increased only on P22. In conclusion, PTGS2 expression increases around the time of luteolysis and concurrent upregulation of PTGFS and PTGES indicates that equine endometrium has increased capability of PTG production around the time of luteolysis. However, pregnancy reduces PTGS2 expression, but maintains the high levels of PTGES during early

To determine the proportion of euthyroid women attending a fertility practice who develop hypothyroidism in very early pregnancy (gestational hypothyroidism [GHT]), and to examine the association of GHT with exogenous gonadotropin treatment. Retrospective cohort study. A private reproductive medicine practice. All healthy women (N = 94) with infertility or recurrent pregnancy loss, TSH level <2.5 mIU/L, negative thyroid peroxidase antibodies at initial evaluation, and not taking thyroid medication, who conceived during an 18-month period. Usual fertility care; 30 women who had received exogenous gonadotropins. Serum TSH level at the time of pregnancy detection. Gestational hypothyroidism (TSH ≥ 2.5 mIU/L) developed in 23 of 94 women (24%). The mean increase in serum TSH level from initial evaluation to early pregnancy was 0.45 ± 0.08 [SE] mIU/L. There was a trend toward the association of GHT with use of exogenous gonadotropins. Gestational hypothyroidism was positively associated with initial prepregnancy TSH level. Euthyroid women may develop mild hypothyroidism in early pregnancy, especially after exogenous gonadotropin treatment. Appropriate vigilance will allow for timely levothyroxine treatment.

It is hypothesized that the following periconceptional and early pregnancy nutrient-gene interactions link vascular-related reproductive complications and cardiovascular diseases in adulthood: (1) Maternal and paternal genetically controlled nutrient status affects the quality of gametes and fertilization capacity; (2) The embryonic genetic constitution, derived from both parents, and the maternal genetically controlled nutrient environment determine embryogenesis and fetal growth; (3) Trophoblast invasion of decidua and spiral arteries is driven by genes derived from both parents as well as by maternal nutritional factors; (4) Angiogenesis, vasculogenesis and vascular function are dependent on the genetic constitution of the embryo, derived from both parents, and the maternal genetically controlled nutritional environment.Early intra-uterine programming of vessels may concern the same (in)dependent determinants of vascular-related complications during pregnancy and cardiovascular diseases in later life.

To compare the efficacy and safety of mifepristone followed by misoprostol with misoprostol alone in the management of early pregnancy failure (EPF). A randomized double-blind placebo-controlled clinical trial. Ninety-two women with EPF ≤12 weeks were recruited and randomly allocated to receive either mifepristone 200 mg ( n  = 46) or placebo ( n  = 46). Forty-eight hours later, patients in both the groups were given 800 µg misoprostol per-vaginum. If no expulsion occurred within 4 h, repeat doses of 400 µg misoprostol were given orally at 3-hourly interval to a maximum of 2 doses in women ≤9 weeks by scan and 4 doses in women >9 weeks by scan. Pre-treatment of misoprostol with mifepristone significantly increased the complete abortion rate (86.7 vs. 57.8%, p  = 0.009) and, hence, reduced the need for surgical evacuation (13.3 vs. 42.2%, p  = 0.002), induction to expulsion interval (4.74 ± 2.24 vs. 8.03 ± 2.77 h, p  = 0.000), mean number of additional doses of misoprostol required (0.68 vs. 1.91, p  = 0.000), and side effects. Use of mifepristone prior to misoprostol in EPF significantly improves the efficacy and reduces the side effects of misoprostol alone.

Objective To determine if an elevated level of the complement activation fragment Bb in early pregnancy was associated with spontaneous preterm birth (SPTB) at less than 34 weeks gestation or SPTB between 34 and 37 weeks gestation (late SPTB). Study Design Prospective study of 784 women enrolled at < 20 weeks gestation. Results Following exclusions, 13 women (1.7%) had a SPTB at less than 34 weeks gestation and 25 (3.2%) a SPTB between 34 and 37 weeks gestation. Women with Bb in the top quartile were 4.7 times more likely to have an SPTB less than 34 weeks gestation as compared with women who had levels of Bb in the lower three quartiles (95% CI 1.5 to 14, P = 0.003). There was no association between Bb and late SPTB (RR= 0.8, 95% CI = 0.3 to 2). Conclusions A significant relationship was found between an elevated Bb in early pregnancy and SPTB < 34 weeks gestation. These results suggest that inflammatory events in early pregnancy are part of the pathogenic mechanisms of this condition. PMID:18928972

Improper or delayed pregnancy diagnosis has significant impact over animal production, particularly in buffaloes which inherently suffer from several reproductive inefficiencies. Thus the present study has undertaken to identify serum protein markers pertaining to early pregnancy diagnosis in buffaloes. Serum samples were collected from 10 pregnant Murrah Buffalo heifers at weekly intervals from days 0-35 post-artificial insemination and from 12 inseminated non-pregnant cyclic buffalo heifers on days 0, 7, 14 and 21. Two-dimensional gel electrophoresis and densitometric analysis revealed the presence of five protein spots showing average density fold change of ≥4 during early pregnancy. Mass spectrometry analysis identified these up-regulated proteins as anti-testosterone antibody light chain, apolipoprotein A-II precursor, serum amyloid A, cytokeratin type II, component IV isoform 1, which are have established roles in embryogenesis, but over-expression of the fifth identified protein immunoglobulin lambda light chain in pregnancy has been elucidated as a novel finding in the current study. Further, with bioinformatics analysis, potential antigenic B-cell epitopes were predicted for all these five proteins. An antibody cocktail-based approach involving antibodies against all these five up-regulated entire proteins or their epitopes could be developed for early detection of pregnancy in buffaloes. © 2016 Japanese Society of Animal Science. © 2016 Japanese Society of Animal Science.

Successful diagnosis and treatment of early splenic ectopic pregnancy: A case report.

Splenic ectopic pregnancy (SEP), a special abdominal pregnancy, is extremely rare but carries a high risk of potentially uncontrollable, life-threatening intraperitoneal bleeding at early gestation, which is equivalent to the spontaneous rupture of the spleen. Therefore, early diagnosis of SEP is crucial and may avoid life-threatening situation. A 29-year-old G3P2 woman presented with 50 days of amenorrhea and positive serum β-human gonadotropin (β-HCG) was enrolled into the hospital due to the absence of gestational sac located in the uterine cavity. A pan-abdominal ultrasound scan revealed a 2.6 cm ×1.6 cm hyperechoic mass inferior to the spleen with color Doppler signal surrounding and 0.9 cm anechoic inside. The gynecologist found the gestational sac was located in the dorsal pole of the spleen through the exploratory laparoscopy. Total splenectomy was performed uneventfully to avoid the hemorrhage shock. The patient discharged with no complications and normal 1-month follow-up. It highlights that fully understanding of the knowledge about abdominal pregnancy, especially splenic pregnancy, and early imaging study with ultrasonography could reduce or avoid the misdiagnosis and miss-diagnosis of SEP.

To determine the role of MRI in the early diagnosis of tubal ectopic pregnancy (EP). Clinical and MRI features of 27 cases of tubal pregnancy were reviewed. A thick-walled gestational sac (GS)-like structure was demonstrated lateral to the uterus in all cases. On T2-weighted images, the thick wall typically exhibited 3 discrete rings in 22 cases (81 %), among which 17 cases (63 %) displayed small vessels and 6 cases (33 %) exhibited small areas of fresh haemorrhage inside the thick wall. The contents demonstrated non-specific liquid in 26 %, papillary solid components in 56 %, and fresh blood or fluid-fluid level in 19 % of the cases. Dilatation of the affected fallopian tube associated with hematosalpinx was demonstrated in 18 cases (67 %) and marked enhancement of the tubal wall was observed in 22 cases (81 %). No correlation was found between the size of the GS and the estimated gestational age (r = 0.056). MRI plays an important role in the early diagnosis and management of tubal pregnancy. The characteristic MRI features include a GS-like structure with a "three rings" appearance on T2-weighted images, presence of solid components in the sac, dilatation of the affected fallopian tube with hematosalpinx, and tubal wall enhancement. • MR imaging has served as a problem-solving procedure in ectopic pregnancy. • MR imaging features can be criteria for early diagnosis of tubal pregnancy. • Detailed assessment of ectopic implantation is necessary for management decision-making.

Previous studies have found associations between individual healthy behaviors and reduced risk of gestational diabetes mellitus (GDM); however, the association of composite healthy lifestyle during pregnancy with GDM has not been examined. Participants in the Omega Study (n = 3,005), a pregnancy cohort study conducted in Washington State (1996-2008), reported information on diet, physical activity, smoking, and stress during early pregnancy. Lifestyle components were dichotomized into healthy/unhealthy and then combined into a total lifestyle score (range, 0-4). Regression models were used to determine relative risk of GDM (n = 140 cases) in relation to healthy lifestyle. Twenty percent of participants had a healthy diet, 66% were physically active, 95% were nonsmokers, and 55% had low stress. Each 1-point increase in lifestyle score was associated with a 21% lower risk of GDM (95% confidence interval: 0.65, 0.96) after adjustment for age, race, and nulliparity. Adjustment for prepregnancy body mass index, prepregnancy physical activity, and prepregnancy smoking attenuated the associations slightly. Associations were similar in normal-weight and overweight/obese women. In this study, a composite measure of healthy lifestyle during early pregnancy was associated with substantially lower GDM risk. Public health messaging and interventions promoting multiple aspects of a healthy lifestyle during early pregnancy should be considered for GDM prevention. © The Author(s) 2017.

Reducing pregnancy loss is important for improving reproductive efficiency for both human and mammalian animals. Our previous study demonstrates that maternal N-carbamylglutamate (NCG) supply during early pregnancy enhances embryonic survival in gilts. However, whether maternal NCG supply improves the pregnancy outcomes is still not known. Here we found maternal NCG supply during early pregnancy in sows significantly increased the numbers of total piglets born alive per litter ( P < 0.05) and significantly changed the levels of metabolites in amniotic fluid and serum involved in metabolism of energy, lipid, and glutathione and immunological regulation. The expression of endometrial progesterone receptor membrane component 1 (PGRMC1) was significantly increased by NCG supplementation ( P < 0.05) as well as the expression of PGRMC1, endothelial nitric oxide synthesases (eNOS), and lamin A/C in fetuses and placentae ( P < 0.05). Among the NCG-associated amino acids, arginine and glutamine, markedly increased PGRMC1 and eNOS expression in porcine trophectoderm cells ( P < 0.05), whereas glutamate could stimulate the expression of vimentin and lamin A/C in porcine trophectoderm (pTr) cells ( P < 0.05) and proline stimulated lamin A/C expression ( P < 0.05). Collectively, these data reveal the mechanisms of NCG in reducing early embryo loss. These findings have important implications that NCG has great potential to improve pregnancy outcomes in human and mammalian animals.

A ewe that is mated as a juvenile (producing a lamb at 1 year of age) will produce an average of only 0.6 lambs to weaning, compared to an average of 1.2 lambs in adult ewes. Understanding the underlying causes of this low reproductive efficiency and designing methods to improve or mitigate these effects could potentially increase adoption of mating juvenile ewes. In Experiment 1, 2 Cohorts of ewes, born a year apart, were mated in order to lamb at 1 and 2 years of age and the performance of the ewes at each age was compared. Onset of puberty, mating by the fertile ram, ovulation rate, early pregnancy (day 30-35) litter size, number of lambs born and number of lambs weaned were measured. In juvenile ewes, by day 35 of pregnancy, 43% of ova had failed to become a viable embryo and this early loss was the largest contributor to the poor reproductive performance observed. Compared with young adult ewes, ovulation rate was lower (p<0.001), fewer ova were exposed to sperm (p<0.001) and fertilization failure/embryo loss was increased (p<0.001) in juveniles. In Experiment 2, the early pregnancy litter size of juveniles was shown to be greater (p<0.001) in those ewes with a greater ovulation rate (p<0.001). Attaining puberty prior to introduction of the fertile ram was associated with an increased pregnancy rate (p<0.001). In juvenile ewes, failure to mate with the ram, lower ovulation rate and increased fertilisation failure/embryo loss underlie their poor reproductive performance. Copyright © 2016 Elsevier B.V.

To determine the etiology and outcome of Acute Renal Failure (ARF) in pregnancy. A case series. Nephrology Department of the Jinnah Postgraduate Medical Centre, Karachi, from August 2007 to July 2008. Pregnant women who were healthy previously and had developed ARF, diagnosed on oliguria (urine output <400 ml/day) and mounting azotemia (serum creatinine > 2 mg%) were included in the study. Percutaneous renal biopsy was performed for delayed recovery, i.e. after three weeks. Patients were followed up for a period of 6 months. Percentages were calculated for qualitative variables i.e. causes of ARF, mortality, morbidity and outcome in form of complete recovery, partial recovery, demise and non-recovery. A total of 43 patients with pregnancy-related ARF were included in the study. The puerperal group comprised 36 patients (83.7%). Haemorrhage was the etiology for ARF in 25 (58.1%), antepartum haemorrhage APH in 8 (18.6%) and postpartum haemorrhage PPH in 16 (37.2%) of patients. In 12 (27.9%), puerperal sepsis was the etiological factor, while 4 (9.3%) patients had DIC on presentation. Pre-eclampsia, eclampsia and HELLP syndrome accounted for 5 (11.6%). While 1 (2.3%) was diagnosed with hemolytic uremic syndrome and another one was diagnosed as ARF secondary to hypotension produced by hyperemesis gravidarum. Renal biopsy was performed in 31 patients showing that 10 had acute cortical necrosis and 21 had acute tubular necrosis. Maternal mortality was 16.2% (n=7). Of the 36 (83.7%) surviving patients, 18 (41.4%) had complete recovery of renal function; 12 (27.9%) had partial recovery; and 6 (13.9%) required chronic dialysis. Pregnancy-related ARF was associated with poor outcome. Antepartum and postpartum haemorrhage were the most common cause of ARF in pregnancy.

Cerebral venous thrombosis (CVT) is an uncommon cause of stroke, accounting to less than 1% of all strokes. We describe a pregnant woman with a massive CVT in early pregnancy, complicated by status epilepticus. The mother was treated with levetiracetam, lacosamide, and enoxaparin throughout pregnancy. A male infant was born on pregnancy week 36, weighing 2.2kg. Both levetiracetam and and lacosamide were present in cord blood in levels similar to those in maternal blood. The infant was partially breast-fed and experienced poor feeding and sleepiness, starting to resolve after two first weeks. Milk samples were drawn 5 days after the delivery and a blood sample from the infant 3 days later. Lacosamide level in milk was low, resulting in an estimated relative infant dose of 1.8% of the maternal weight-adjusted daily dose in a fully breast-fed infant. This is the first case describing lacosamide use during pregnancy and lactation. Copyright © 2015 Elsevier Inc. All rights reserved.

OBJECTIVE: To establish normal parameters in early pregnancy through transvaginal ultrasonography so that gestational age can be determined and to correlate the sonographic findings with serum human chorionic gonadotropin (hCG) levels calibrated against the first international reference preparation standard. SETTING: Infertility clinic. PATIENTS: Thirty-five women with normal intrauterine pregnancy. INTERVENTIONS: Serial measurement of the serum hCG level and the diameter of the gestational sac through transvaginal ultrasonography. MAIN RESULTS: The gestational sac could not be visualized when the hCG level was less than 1100 IU/L. The average growth rate of the sac was 0.9 mm/d. The threshold values for sac diameter, serum hCG level and gestational age below which the yolk sac was not visible were 3.7 mm, 1900 IU/L and 36 days respectively; the corresponding values above which the yolk sac was always visible were 6.7 mm, 5800 IU/L and 40 days. The threshold values below which cardiac activity was not visible were 8.3 mm, 9200 IU/L and 41 days respectively, and the corresponding values above which cardiac activity was always visible were 14.0 mm, 24,000 IU/L and 46 days. The mean gestational ages and the 95% confidence and prediction intervals were tabulated so that measurement of the gestational sac diameter could be used to estimate gestational age early in normal pregnancy. CONCLUSIONS: Transvaginal ultrasonography enables detection of an intrauterine sac and reliable estimation of gestational age on the basis of sac dimensions before an embryo can be seen.

Hypertensive diseases are directly responsible for 24 % of maternal deaths in India. A screening method is yet to be discovered to reduce the morbidity and mortality related to it. Serum triglyceride (TG) levels are reported to increase in hypertensive pregnant women. To predict pregnancy-induced hypertension (PIH) by serum triglyceride values. This study is a prospective cohort study that was conducted over three hundred normotensive, primigravida women with singleton pregnancy at 14-20 weeks of gestation. These were divided into two groups on the basis of their TG concentration estimated at 14-20 weeks of gestation. The pregnancy was then followed till delivery and, signs and symptoms of PIH were noted in both the groups. Out of 300 women, 210 women completed the study. Fifty-nine women developed PIH and 151 women remained normotensive. Among 59 women, 45 women had raised TG values i.e., ≥160 mg/dL and 14 women were with normal TG levels i.e., <160 mg/dL. A significant positive correlation was found between serum TG concentration and systolic and diastolic blood pressure. It was observed that a cutoff of 162.50 mg/dL for TG could reliably predict PIH with sensitivity of 76 % and specificity of 85 %. Also, the mothers with hypertriglyceridemia were found to be at higher risk of developing early-onset PIH. Our study supports the evidence that early pregnancy hypertriglyceridemia is associated with an increased risk of PIH.

Early pregnancy factor (EPF) is an immunosuppressive protein detected in the early pregnancy serum. We have already reported that we developed the rosette inhibition test for mare EPF and detected EPF in thoroughbreds. The aim of this study was to determine whether or not our method could be used clinically. The rosette inhibition test for equine EPF was carried out on serum from six nonpregnant and six pregnant Shetland ponies, a female and a male Chinese pony, and four nonpregnant and 13 pregnant thoroughbred mares. In the thoroughbreds sera were collected during the pregnancy period. Furthermore, we measured progesterone and detected pregnant mare serum gonadotrophin (PMSG) in order to confirm pregnancy of the Chinese pony 3 and 6 months after mating. In the nonpregnant Shetland ponies, the rosette inhibition titre (RIT) was 6.0+/-1.0 and EPF was negative. In contrast, in the pregnant ponies, the RIT was 9.2+/-0.4 and EPF was positive. Based on these results, we diagnosed pregnancy of the Chinese pony. The RIT of the female Chinese pony (3 months after mating) was above 10 and EPF was positive. Furthermore, we detected PMSG and progesterone in the serum of this pony. EPF appeared in the maternal blood circulation at 24-72 hr after mating, it was detected until the second trimester, and after that it disappeared from the maternal serum. The pony's EPF was detected by using the same rosette inhibition test as in the thoroughbred and was present from 24 to 72 hr after mating until the second trimester. The results indicated that our method was useful for pregnancy diagnosis of Equine.

The aim of this study was to evaluate whether the presence of history of biochemical pregnancy (BP) was associated with clinical characteristics and the subsequent pregnancy outcome among women with recurrent spontaneous abortion (RSA). One-hundred and seventy-five RSA women with two or more clinical pregnancy losses were enrolled. The clinical characteristics were compared between 164 women with history of 0-1 BP (Group A) and 11 women with two or more BP (Group B). The frequency of previous pregnancy loss and history of in vitro fertilization and embryo transfer in Group B was higher than that in Group A; while frequency of secondary RSA in Group B was lower than Group A. The subsequent pregnancy outcome was assessed prospectively; and live-birth rate in Group A (72.9%) was higher (p < 0.05) than that in Group B (41.7%). The incidence of reproductive failure (58.3%, p < 0.05) and spontaneous abortion with normal chromosome (25.0%, p = 0.050) in Group B was higher than those (27.1 and 5.9%, respectively) in Group A. RSA women with two or more BP had higher risk of reproductive failure and spontaneous abortion with normal chromosome together with lower chance of live-birth. The results of the present study involve important information and are helpful for clinical practitioners.

Purpose: Oral cancer patients with platinum-resistant disease and or early failures have limited treatment options. This analysis was planned to study the efficacy of metronomic chemotherapy in this group of patients. Materials and Methods: This was a retrospective analysis of oral cancer patients who had squamous cell carcinoma and had an early failure and/or platinum-insensitive failure. Early failure was defined as a failure either within 1-month of adjuvant radiotherapy or within 6 months of chemoradiation (CTRT). A sample size of 100 patients was selected for this study. If ≥39 of 100 patients would have survived at 6 months with metronomic chemotherapy, then additional studies would be warranted. Results: The ECOG PS was 0-1 in 92 patients and 2 in 8 patients. The subsite of primary was buccal mucosa in 38 patients (38%), anterior two-third tongue (oral tongue) in 51 patients (51%), and alveolus in 11 patients (11%). The median estimated overall survival was 110 days (95% confidence interval [CI]: 85-134 days). The proportion of patients surviving at 6 months was 26.4% (95% CI: 17.9-35.6). Conclusion: Metronomic combination of methotrexate and celecoxib failed to meet its prespecified efficacy limit and should not be used in these patients as routine. PMID:26855524

Female sex is an independent predictor of better survival in patients with heart failure but the mechanism of this association is unknown. On the other hand, pregnancies have a strong influence in the cardiovascular system. Sex and previous gestations might have a prognostic impact on one-year mortality in patients admitted with heart failure. Observational prospective consecutive multicenter registry of 1831 patients (756 women [41.2%]) admitted with heart failure. Women had a more advanced age (75.2±11.4 vs. 70.4±12.2 years), less ischemic heart disease (167 [25.3%] vs.446 [47.3]), and higher left ventricular ejection fraction (52.0±16.6 vs. 41.1±17.0) than men, all p values <0.001. During one-year follow-up, 373 (20.4%) patients died, (151 women and 222 men). Female sex was an independent predictor for survival, hazard ratio 0.79 (95% confidence interval 0.64-0.98, p=0.03). In 504 women (65.9%) the exact number of previous pregnancies could be determined; 62 had no previous pregnancies (12.3%), 288 one or two (57.1%), and 154 three or more (30.6%). We found an association between the number of previous gestations and better survival, hazard ratio 0.878 (95% confidence interval 0.773-0.997, p=0.045). In patients admitted with heart failure, female sex and the number of previous pregnancies are independently associated with better 1-year survival. This article is protected by copyright.

This clinic- and community-based study of young women investigated the relationship between previous sexual abuse and early pregnancy, examining the effect of the developmental period in which sexual abuse occurred and type of sexual abuse, while also providing methodological advances in the assessment of distinctive sexual abuse and its sequelae. Secondary data analysis using Cox proportional hazards models was conducted to determine the association between sexual abuse in childhood, in adolescence, or both, and risk of early pregnancy among 1,790 young women. In addition, this study examined the type of sexual abuse that occurred during each period. As compared with women with no history of sexual abuse, women who experienced sexual abuse only in childhood had a 20% greater hazard of pregnancy; women who experienced sexual abuse only in adolescence had a 30% greater hazard of pregnancy; and women who experienced sexual abuse in both childhood and adolescence had an 80% greater hazard of pregnancy. Across these periods, attempted rape and rape were associated with an increased hazard of pregnancy. The association between sexual abuse and pregnancy was mediated by age at first intercourse and moderated by a woman's education level. This study provides evidence that both the developmental timing and the type of sexual abuse contributes to an increased risk for early pregnancy. The study findings indicate that sexual abuse leads to an earlier age of first sexual intercourse, which in turn increases the likelihood of an early pregnancy. Women with higher educational attainment are less likely to experience early pregnancy as a result of abuse. Copyright © 2011 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

The objective of this study was to determine whether an elevated level of the complement activation fragment Bb in early pregnancy was associated with spontaneous preterm birth (SPTB) at less than 34 weeks' gestation or SPTB between 34 and 37 weeks' gestation (late SPTB). This was a prospective study of 784 women enrolled at less than 20 weeks' gestation. Following exclusions, 13 women (1.7%) had a SPTB at less than 34 weeks' gestation and 25 (3.2%) a SPTB between 34 and 37 weeks' gestation. Women with Bb in the top quartile were 4.7 times more likely to have an SPTB less than 34 weeks' gestation as compared with women who had levels of Bb in the lower 3 quartiles (95% confidence interval [CI] 1.5-14, P = .003). There was no association between Bb and late SPTB (relative risk 0.8, 95% CI 0.3-2). A significant relationship was found between an elevated Bb in early pregnancy and SPTB less than 34 weeks' gestation. These results suggest that inflammatory events in early pregnancy are part of the pathogenic mechanisms of this condition.

Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality. The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of 'low risk' women participating in a large international multicentre prospective study (n = 5 609), to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation. The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization's definition of anaemia in pregnancy (haemoglobin < 11g/dL). Binary logistic regression with adjustment for potential confounders (country, maternal age, having a marital partner, ethnic origin, years of schooling, and having paid work) was the main method of analysis. The hallmark findings were the low prevalence of anaemia (2.2%), that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78), and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score < 7 at one and five minutes). Adverse pregnancy outcomes were however more common in those with anaemia than in those without. In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia's conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy.

The aim of this study was to compare two methods of early pregnancy diagnosis by determining pregnancy-associated glycoprotein (PAG) concentration in blood and PAG concentration in milk. Blood and milk samples were obtained on days 0 (AI day), 14, 21, 28, 35, 49, 63, 77, 91 and 105 of gestation from 60 lactating Holstein Frisian cows from one herd, carrying live fetuses. To determine PAG concentration a specific RIA system (RIA-706) was used. PAG concentration in blood and milk increased after 28 days of pregnancy, with blood concentrations being significantly higher than in milk. However, the accuracy of both tests at this time point was similar (sensitivity: 92 % in blood, 93 % in milk; specificity 53 % and 60 % respectively). None of the tests were able to detect open cows properly at this stage. On day 35 of gestation sensitivity (100 % for blood, 97 % for milk) and specificity (100 % for blood, 100 % for milk) were high enough to be used for reliable pregnancy diagnosis. The accuracy (sensitivity and specificity) for PAG concentrations in blood and milk for the rest of the study was 100 %. Our investigation shows that PAG determination in milk is a stress-free and non-invasive method for early pregnancy diagnosis in cattle.

BACKGROUND The aim was to evaluate the impact of early pregnancy events and complications as predictors of adverse obstetric outcome. METHODS We conducted a literature review on the impact of first trimester complications in previous and index pregnancies using Medline and Cochrane databases covering the period 1980-2008. RESULTS Clinically relevant associations of adverse outcome in the subsequent pregnancy with an odds ratio (OR) > 2.0 after complications in a previous pregnancy are the risk of perinatal death after a single previous miscarriage, the risk of very preterm delivery (VPTD) after two or more miscarriages, the risk of placenta praevia, premature preterm rupture of membranes, VPTD and low birthweight (LBW) after recurrent miscarriage and the risk of VPTD after two or more termination of pregnancy. Clinically relevant associations of adverse obstetric outcome in the ongoing pregnancy with an OR > 2.0 after complications in the index pregnancy are the risk of LBW and very low birthweight (VLBW) after a threatened miscarriage, the risk of pregnancy-induced hypertension, pre-eclampsia, placental abruption, preterm delivery (PTD), small for gestational age and low 5-min Apgar score after detection of an intrauterine haematoma, the risk of VPTD and intrauterine growth restriction after a crown-rump length discrepancy, the risk of VPTD, LBW and VLBW after a vanishing twin phenomenon and the risk of PTD, LBW and low 5-min Apgar score in a pregnancy complicated by severe hyperemesis gravidarum. CONCLUSIONS Data from our literature review indicate, by finding significant associations, that specific early pregnancy events and complications are predictors for subsequent adverse obstetric and perinatal outcome. Though, some of these associations are based on limited or small uncontrolled studies. Larger population-based controlled studies are needed to confirm these findings. Nevertheless, identification of these risks will improve obstetric care.

The role of thyroid hormone in trophoblast function, early pregnancy maintenance, and fetal neurodevelopment.

To review the literature on the roles of thyroid hormone in trophoblast function, early pregnancy maintenance, and fetal neurodevelopment. MEDLINE was searched for English-language papers published from 1971 to 2003, using the key words "brain," "hypothyroidism," "placenta," "pregnancy," "threatened abortion," "thyroid hormone," "thyroid hormone receptor," "thyroid hormone replacement therapy," "thyroid hormone-responsive gene," and "trophoblast." Transplacental transfer of thyroid hormone occurs before the onset of fetal thyroid hormone secretion. Thyroid hormone receptors and iodothyronine deiodinases are present in the placenta and the fetal central nervous system early in pregnancy, and thyroid hormone plays a crucial role both in trophoblast function and fetal neurodevelopment. Maternal hypothyroxinemia is associated with a high rate of spontaneous abortion and long-term neuropsychological deficits in children born of hypothyroid mothers. Maternal iodine deficiency also causes a wide spectrum of neuropsychological disorders in children, ranging from subclinical deficits in cognitive motor and auditory functions to hypothyroid-induced cognitive impairment in infants. However, these conditions are preventable when iodine supplementation is initiated before the second trimester. Although thyroid hormone replacement therapy is effective for reducing the adverse effects complicated by maternal hypothyroidism, the appropriate dose of thyroid hormone is mandatory in protecting the early stage of pregnancy. Close monitoring of maternal thyroid hormone status and ensuring adequate maternal thyroid hormone levels in early pregnancy are of great importance to prevent miscarriage and neuropsychological deficits in infants.

The contribution of systemic S100A8 protein in menstrual cycle, pregnancy, and early pregnancy loss (EPL) is not known. Altered expression of S100A8 in maternal decidua is associated with recurrent early pregnancy loss. The objective of this study was to investigate the systemic level of S100A8 in different phases of menstrual cycle, different trimester of pregnancy, and in EPL. Level of S100A8 was investigated in serum samples of the subjects through enzyme-linked immunosorbent assay (ELISA). S100A8 levels were elevated during proliferative phase of menstrual cycle. We found no statistical difference in S100A8 level in different trimester of pregnancy. S100A8 level was found to be significantly elevated in patients with EPL. This is the first study evaluating the systemic level of S100A8 predicting its role during menstrual cycle and pregnancy. It opens a new perspective in which S100A8 can be used as a prognostic marker for EPL. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In patients with pulmonary hypertension, pregnancy is associated with a high risk of maternal death. Such patients are counselled to avoid pregnancy, or if it occurs, are offered early interruption. Some patients, however, decide to continue with their pregnancy and others may present with symptoms for the first time whilst pregnant. Pulmonary vasodilator therapy provides a treatment option for these high-risk patients. The present study describes three patients with pulmonary arterial hypertension of various aetiologies who were treated with the prostacyclin analogue iloprost during pregnancy, and the post-partum period. Nebulised iloprost commenced as early as 8 weeks of gestation and patients were admitted to hospital between 24-36 weeks of gestation. All pregnancies were completed with a duration of between 25-36 weeks and all deliveries were by caesarean section under local anaesthetic. All patients delivered children free from congenital abnormalities, and there was no post-partum maternal or infant mortality. In conclusion, although pregnancy is strongly advised against in those with pulmonary hypertension, the current authors have achieved a successful outcome for mother and foetus with a multidisciplinary approach and targeted pulmonary vascular therapy.

Early parenting practices, such as infant feeding, can affect children's physical health. Additionally, negative prenatal maternal affect can influence feeding choices, such as breast-feeding, and can have a detrimental effect on children's health. Little is known, however, about the contribution of positive maternal affect during pregnancy on feeding practices and children's health. This study explored whether positive prenatal feelings influenced children's health during the first 18 months, and whether early feeding practices mediated the relationship between these two variables. Low-income, ethnically diverse, primiparous women (n = 114) reported their feelings of pregnancy uplifts and hassles during their third trimester. These women were interviewed again at 2, 4, 6, 9, 12, and 18 months post-partum about their feeding practices. A retrospective audit of their infants' medical charts was completed from birth to 18 months. Using structural equation modeling, having more uplifts than hassles during pregnancy was associated with longer breast-feeding duration and greater adherence to recommended schedules for introducing fruits and vegetables, solids, and baby cereal. These feeding practices were linked to better child health outcomes, including reduced risk of upper respiratory tract infections, conjunctivitis, otitis media, and thrush. Positive maternal feelings during pregnancy were associated with better feeding practices, and these better feeding practices were associated with fewer common childhood illnesses. Helping expectant women focus on the positive aspects of their pregnancy may lead to postnatal care methods that are fiscally advantageous, preventive of detrimental postnatal choices, and medically beneficial for children. © 2016 Japan Pediatric Society.

Pregnancy is associated with significant changes in vitamin D metabolism, notably increased maternal serum levels of active vitamin D, 1,25-dihydroxyvitamin (1,25(OH) 2 D). This appears to be due primarily to increased renal activity of the enzyme 25-hydroxyvitamin D-1α-hydroxylase (CYP27B1) that catalyzes synthesis of 1,25(OH) 2 D, but CYP27B1 expression is also prominent in both the maternal decidua and fetal trophoblast components of the placenta. The precise function of placental synthesis of 1,25(OH) 2 D remains unclear, but is likely to involve localized tissue-specific responses with both decidua and trophoblast also expressing the vitamin D receptor (VDR) for 1,25(OH) 2 D. We have previously described immunomodulatory responses to 1,25(OH) 2 D by diverse populations of VDR-expressing cells within the decidua. The aim of the current review is to detail the role of vitamin D in pregnancy from a trophoblast perspective, with particular emphasis on the potential role of 1,25(OH) 2 D as a regulator of trophoblast invasion in early pregnancy. Vitamin D deficiency is common in pregnant women, and a wide range of studies have linked low vitamin D status to adverse events in pregnancy. To date, most of these studies have focused on adverse events later in pregnancy, but the current review will explore the potential impact of vitamin D on early pregnancy, and how this may influence implantation and miscarriage. © 2018 Society for Endocrinology.

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 (de)regulated pathways in the pathophysiology of ectopic pregnancy in humans. PMID:24498170

Quality of life, comfort, and wellbeing during pregnancy are essential for every country in the world. Pregnancy is considered a preparation period for becoming a mother. Maternal role development, including confidence and satisfaction as a mother, is important in the transition to motherhood. Negative psychosocial affect, such as increased anxiety and distress, during pregnancy adversely influences the childbirth experience and childcare, which contributes to postpartum depression. However, the impact of positive feelings on the maternal role development remains unclear. Therefore, the study purpose was to clarify the relationship between comfort in late pregnancy and maternal role attainment and childcare during early postpartum. We designed a descriptive, longitudinal, correlational study by using the Prenatal Comfort Scale, the Postpartum Maternal Role Confidence Scale, and the Postpartum Maternal Satisfaction Scale. Among 339 participants who had received care at a university hospital located in Sendai city in Japan, 215 subjects completed the longitudinal study by answering a questionnaire for the respective Scale late in their pregnancy or during early postpartum. The subjects consisted of 114 primipara (32.0 ± 5.4 years) and 101 multipara (33.4 ± 4.9 years). In primipara, comfort with motherhood was significantly correlated with maternal confidence regarding knowledge and childcare skills and maternal satisfaction. In multipara, comfort in late pregnancy was related to maternal confidence and satisfaction. Positive affect was related to maternal confidence and maternal satisfaction in early postpartum. Therefore, a prenatal nursing intervention helps women become more comfortable with impending motherhood, thereby promoting maternal role attainment after delivery.

Maternal smoking during pregnancy is a major cause of intrauterine growth restriction and childhood obesity, but only a few studies have examined the association of smoking cessation before and during pregnancy with fetal and childhood growth. We examined this association in a prospective cohort study in Japan. Our study included children born between 1991 and 2006 and their mothers. Using a questionnaire, maternal smoking status was recorded at pregnancy. The anthropometric data of the children were collected during a medical check-up at age 3 years. Multiple linear and logistic regression models were used for data analysis stratified by sex. In total, 2663 mothers reported their smoking status during early pregnancy, and data were collected from 2230 (83.7%) children at age 3 years. Maternal smoking during pregnancy was associated with a significant reduction in birth weight (approximately 120-150 g). Body mass index at age 3 years was significantly higher among boys born to smoking mothers than among boys born to nonsmoking mothers. Maternal smoking during pregnancy was associated with overweight at age 3 years among boys (adjusted odds ratio, 2.4; 95% CI, 1.03-5.4). However, among women who stopped smoking in early pregnancy, there was no increase in the risks of a small for gestational age birth or childhood overweight at age 3 years. Children born to mothers who stopped smoking before or during early pregnancy had appropriate fetal and childhood growth.

To evaluate the predictive value of three-dimensional (3D)-power Doppler sonography on recurrent miscarriage. The study patients were divided into a recurrent miscarriage group (30 cases) and a normal pregnancy group (21 cases). Measurement of endometrial thickness was performed using two-dimensional transvaginal ultrasound in the midluteal phase. The endometrial volume, vascularization index (VI), flow index (FI), and vascularization-flow index (VFI) in midluteal and placenta volume, as well as the VI, FI, and VFI of early pregnancy were measured using Virtual Organ Computer-aided Analysis of 3D-power Doppler ultrasound. Endometrial thickness, endometrial volume, endometrial vascular data, VI, FI, and VFI of the midluteal phase were lower in the recurrent miscarriage group compared with the normal pregnancy group (p < 0.05). Placental volume, VI, and VFI during early pregnancy were lower in the miscarriage group compared with the normal pregnancy group (p < 0.05). There was no significant change in FI between the recurrent miscarriage and control groups during early pregnancy (p > 0.05). The predictive accuracy of endometrial thickness, endometrial volume, VI, FI, and VFI in the midluteal phase, and placenta volume, VI, FI, and VFI in early pregnancy as measured by the receiver operating characteristic curve to predict miscarriage before 12 gestational weeks in participants was 0.681, 0.876, 0.770, 0.720, 0.879, 0.771, 0.907, 0.592, respectively. The 3D-power Doppler ultrasound is a more comprehensive and sensitive method for evaluating endometrial receptivity. Endometrial volume, VI, FI, and VFI in the midluteal phase, as well as VI in early pregnancy, can be considered as predictive factors for recurrent miscarriage. Copyright © 2015.

The aim of this study was to compare chronic fallopian tubal inflammatory disease and fibrosis between patients with general tubal pregnancy (TP) and TP with levonorgestrel (LNG) emergency contraception (EC) failure. We retrospectively studied patients with general TP (n = 79) and TP following LNG-EC failure (n = 81) within the same conception cycle. Information on the gynecological features of each subject was collected. Pelvic inflammatory disease and associated sequelae were assessed by the serum Chlamydia trachomatis (CT) IgG test, laparoscopic evaluation of tubal damage, and histopathological observation of tube tissues. Chi-square and Student's t-tests were employed to determine the difference between the two groups. Compared with general TP, cases of TP following LNG-EC failure subjects were less likely to have a history of previous ectopic pregnancy (5.06% vs. 18.52%, p = 0.009) and adnexal surgery (6.33% vs. 22.22%, p = 0.010). Patients with TP following LNG-EC failure were less likely to have pelvic inflammatory disease and associated sequelae than those with general TP, as revealed by positive reaction to anti-CT IgG (18.18% vs. 35.94%, p = 0.031), assessment of tubal damage (grade I: 5.06% vs. 17.28%; grade II: 2.53% vs. 11.11%; grade III: 1.27% vs. 6.17%; p = 0.001), infiltration of chronic inflammatory cells (10.91% vs. 62.50%, p < 0.001), and positive Masson's staining (7.69% vs. 39.58%; p < 0.001). Compared with cases of general TP, cases of TP following LNG-EC failure exhibited reduced rates of CT infection, fallopian tubal inflammation, and/or fibrosis.

Objective: To evaluate the relations between hypertensive disorders (HDP) in pregnancy and early-term birth. Methods: A total of 3 474 pregnant women were consecutively recruited. Demographic information was collected in early pregnancy. HDP was diagnosed in the first, second and third trimesters, respectively. On the basis of precise evaluation on gestation age, early-term birth was defined as gestational age of 37-38 weeks+6 days. Logistic regression models were conducted to examine the associations between HDP and early-term birth. Results: The current study included 3 260 pregnant women, with the rates of HDP, pregnancy-induced hypertension syndrome and pre-eclampsia as 6.0% ( n =194), 4.2% ( n =137) and 1.8% ( n =57), respectively. After controlling for potential confounders, no significant differences between pregnancy-induced hypertension syndrome and earlyterm birth ( OR =1.49, 95% CI : 0.94-2.36) were found. Pre-eclampsia appeared to have increased the risk of early-term birth ( OR =4.46, 95% CI : 2.09-9.54). Conclusion: Pre-eclampsia could significantly increase the risk of early-term birth. This finding suggested that early detection and intervention programs were helpful in reducing the risk of early-term birth.

Are female orphans at risk for early marriage, early sexual debut, and teen pregnancy? Evidence from sub-Saharan Africa.

PubMed

Palermo, Tia; Peterman, Amber

2009-06-01

Female orphans are widely cited as being at risk for early marriage, early childbearing, and risky sexual behavior; however, to date no studies have examined these linkages using population-level data across multiple countries. This study draws from recent Demographic and Health Surveys from ten sub-Saharan African countries to examine the relationship between orphanhood status and measures of early marriage, early sexual debut, and teen pregnancy among adolescent girls aged 15 to 17. Results indicate that, overall, little association is found between orphanhood and early marriage or teen pregnancy, whereas evidence from seven countries supports associations between orphanhood and early sexual debut. Findings are sensitive to the use of multivariate models, type of orphan, and country setting. Orphanhood status alone may not be a sufficient targeting mechanism for addressing these outcomes in many countries; a broader, multidimensional targeting scheme including orphan type, schooling, and poverty measures would be more robust in identifying and aiding young women at risk.

Normal pregnancy is associated with an increase in thrombin generation from the very early stages of the first trimester.

Pregnancy is a hypercoagulable state associated with an increased risk of venous thrombosis, which begins during the first trimester, but the exact time of onset is unknown. Thrombin generation, a laboratory marker of thrombosis risk, increases during normal pregnancy but it is unclear exactly how early this increase occurs. We assessed thrombin generation by Calibrated Automated Thrombography in women undergoing natural cycle in vitro fertilization, who subsequently gave birth at term following a normal pregnancy (n=22). Blood samples were taken just prior to conception and repeated five times during very early pregnancy, up to Day 59 estimated gestation. Mean Endogenous Thrombin Potential (ETP), peak thrombin generation and Velocity Index (VI) increased significantly from pre-pregnancy to Day 43 gestation (p=0.024-0.0004). This change persisted to Day 59 gestation. The mean of the percentage change from baseline, accounting for inter-individual variation, in ETP, peak thrombin and VI increased significantly from pre-pregnancy to Day 32 gestation (p=0.0351-<0.0001) with the mean increase from baseline persisting to Day 59 gestation. Thrombin generation increases significantly during the very early stages of normal pregnancy when compared to the pre-pregnancy state. The increased risk of venous thrombosis therefore likely begins very early in a woman's pregnancy, suggesting that women considered clinically to be at high thrombotic risk should start thromboprophylaxis as early as possible after a positive pregnancy test.

Cerebral venous thrombosis (CVT) rarely induces subarachnoid hemorrhage (SAH). During late pregnancy and puerperium, CVT is an uncommon but important cause of stroke. However, severe SAH resulting from CVT is extremely rare during early pregnancy. We report on a rare case of severe SAH due to CVT, and discuss the potential pitfalls of CVT diagnosis in early pregnancy. A 32-year-old pregnant woman (9th week of pregnancy) presented with slight head dullness. Initial magnetic resonance imaging (MRI) revealed focal, abnormal signal intensity in the left thalamus. Nine days later, the patient developed a generalized seizure and severe SAH was detected with computed tomography (CT) scan. MRI and cerebral angiography revealed a completely thrombosed superior sagittal sinus, vein of Galen, straight sinus, and right transverse sinus. Transvaginal sonography indicated a missed abortion. The day after admission, the patient presented again with a progressive loss of consciousness and signs of herniation. The patient underwent emergency decompressive craniotomy, followed by intrauterine curettage. Two months later, she made an excellent recovery except for a slight visual field defect. A rare case of severe SAH due to CVT is reported, with emphasis on the potential pitfalls of CVT diagnosis in early pregnancy. Copyright © 2013 Elsevier Inc. All rights reserved.

Acute renal failure (ARF) is a serious medical complication during pregnancy, and, in the post-partum period, is associated with significant maternal morbidity and mortality as well as fetal loss. The objective of our study is to find the etiology and maternal outcome of ARF during pregnancy. The study was conducted at the Obstetrics and Gynecology Department of the Institute of Kidney Disease and Research Center, Ahmedabad, India from January 2009 to January 2011. Fifty previously healthy patients who developed ARF, diagnosed on oliguria and serum creatinine >2 mg%, were included in the study. Patients with a known history of renal disease, diabetes and hypertension were excluded from the study. All patients were followed-up for a period of six months. Patient re-cords, demographic data, urine output on admission and preceding history of antepartum hemorrhage (APH), post-partum hemorrhage (PPH), septicemia, operative interventions and retained product of conception were noted and need for dialysis was considered. Patients were thoroughly examined and baseline biochemical investigations and renal and obstetrical ultrasound were performed on each patient and bacterial culture sensitivity on blood, urine or vaginal swabs were performed in selected patients. The age range was 19-38 years (mean 26 ± 3.8). The first trimester, second trimester and puerperal groups comprised of four (8%), 25 (50%) and 21 patients (42%), respectively. Hemorrhage was the etiology for ARF in 15 (30%), APH in ten (20%) and PPH in five (10%) patients. Eleven (22%) patients had lower segment cesarian section (LSCS) while 36 (78%) patients had normal vaginal delivery. In 20 (40%) patients, puerperal sepsis was the etiological factor, while pre-eclampsia, eclampsia and HELLP syndrome accounted for 18 (36%) patients. Two (4%) patients had disseminated intravascular coagulation on presentation while one (2%) patient was diagnosed with hemolytic uremic syndrome. Maternal mortality was 12% (n = 6

Background Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality. Objective The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of ‘low risk’ women participating in a large international multicentre prospective study (n = 5 609), to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation. Methods The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization’s definition of anaemia in pregnancy (haemoglobin < 11g/dL). Binary logistic regression with adjustment for potential confounders (country, maternal age, having a marital partner, ethnic origin, years of schooling, and having paid work) was the main method of analysis. Results The hallmark findings were the low prevalence of anaemia (2.2%), that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78), and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score < 7 at one and five minutes). Adverse pregnancy outcomes were however more common in those with anaemia than in those without. Conclusion In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia’s conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy. PMID:25875012

Social, medical, psychological and economic problems are often associated to teen pregnancy. This is a reality worldwide; Puerto Rico is not an exception, documented in statistics and previous research projects. There are many risks associated with pregnancies among adolescents, including increased maternal morbidity and infant morbidity. In Puerto Rico, the adolescent repeat births reed are 22% for a second child and 6% for a third child. Repeated teen pregnancy has a higher than expected incidence; therefore the investigation of psychosocial factors associated with failure to use contraception is needed,especially to address the intervention at clinics with this population of different needs, mainly when these patients with repeated teen pregnancies have been through the health care system already. The project is a cross sectional survey study, seventy articipants between 12-19 years of age who attended obstetrics or postpartum clinics at an adult University Hospital. A self-administered questionnaire included some psychosocial factors that have been associated withthe failure to use contraceptives as well as demographics tion, education, socioeconomic status and support system. Their partner's age ranged from 15 to 38 years of age. Most participants lived with their partner. Their main activity at the time of the study was housework. Most had left school beforebecoming pregnant and received government help. Of all participants, a small number was legally married. The lack of use of contraceptive was found to be significantly associated to partner (p < 0.05). The lack of contraceptive use is a key factor in adolescent pregnancy. It is expected that this data can be helpful for documentation and intervention measurements something canbe done at an educational level, family planning and medical care.

Pre-eclampsia is considerably more prevalent in low- than high-income countries. One possible explanation for this discrepancy is dietary differences, particularly calcium deficiency. Calcium supplementation in the second half of pregnancy reduces the serious consequences of pre-eclampsia and is recommended by the World Health Organization (WHO) for women with low dietary calcium intake, but has limited effect on the overall risk of pre-eclampsia. It is important to establish whether calcium supplementation before and in early pregnancy has added benefit. Such evidence would be justification for population-level fortification of staple foods with calcium. To determine the effect of calcium supplementation or food fortification with calcium, commenced before or early in pregnancy and continued at least until mid-pregnancy, on pre-eclampsia and other hypertensive disorders, maternal morbidity and mortality, as well as fetal and neonatal outcomes. We searched the Cochrane Pregnancy and Childbirth Trials Register (10 August 2017), PubMed (29 June 2017), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (10 August 2017) and reference lists of retrieved studies. Randomised controlled trials of calcium supplementation or food fortification which include women of child bearing age not yet pregnant, or in early pregnancy. Cluster-RCTs, quasi-RCTs and trials published in abstract form only would have been eligible for inclusion in this review but none were identified. Cross-over designs are not appropriate for this intervention.The scope of this review is to consider interventions including calcium supplementation with or without additional supplements or treatments, compared with placebo or no intervention. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. This review is based on one RCT (involving 60 women) which looked at calcium plus additional supplements

Virologic failure of HIV-positive patients is of special concern during pregnancy. We compared virologic failure and the frequency of treatment changes in pregnant and non-pregnant women of the Swiss HIV Cohort Study. Using data on 372 pregnancies in 324 women we describe antiretroviral therapy during pregnancy. Pregnant women on HAART at conception (n = 131) were matched to 228 non-pregnant women (interindividual comparison) and to a time period of equal length before and after pregnancy (intraindividual comparison). Women starting HAART during pregnancy (n = 145) were compared with 578 non-pregnant women starting HAART. The median age at conception was 31 years, 16% (n = 50) were infected through injecting drug use and the median CD4 cell count was 489 cells/microl. In the majority of pregnancies (n = 220, 59%), women had started ART before conception. When ART was started during pregnancy (n = 145, 39%), it was mainly during the second trimester (n = 100, 69%). Two thirds (n = 26) of 35 women starting in the third trimester were diagnosed with HIV during pregnancy. The risk of virologic failure tended to be lower in pregnant than in non-pregnant women [adjusted odds ratio 0.52 (95% confidence interval 0.25-1.09, P = 0.08)], but was similar in the intraindividual comparison (adjusted odds ratio 1.04, 95% confidence interval 0.48-2.28). Women starting HAART during pregnancy changed the treatment less often than non-pregnant women. Despite the physiological changes occurring during pregnancy, HIV infected pregnant women are not at higher risk of virologic failure.

Poor reproductive performance remains a major issue in the dairy industry, with low conception rates having a significant impact on milk production through extended calving intervals. A major limiting factor is the lack of reliable methods for early pregnancy diagnosis. Identification of animals within a herd that fail to conceive within 3 weeks after insemination would allow early re-insemination and shorten calving intervals. In a previous study, we found an increase in plasma miR-26a levels in Day 16-pregnant relative to non-pregnant heifers, however changes in miRNA levels that early during pregnancy were very small which likely prevented the identification of robust biomarkers. In this study, we extended our analyses to a wider interval during pregnancy (Days 8 to 60, n = 11 heifers) with the rationale that this may facilitate the identification of additional early pregnancy miRNA biomarkers. Using small RNA sequencing we identified a total of 77 miRNAs that were differentially expressed on Day 60 relative to Day 0 of pregnancy. We selected 14 miRNAs for validation by RT-qPCR and confirmed significant differences in the expression of let-7f, let-7c, miR-30c, miR-101, miR-26a, miR-205 and miR-143 between Days 0 and 60. RT-qPCR profiling throughout Days 0, 8, 16 and 60 of pregnancy showed a distinct increase in circulating levels of miR-26a (3.1-fold, P = 0.046) as early as Day 8 of pregnancy. In summary, in contrast to earlier stages of pregnancy (≤ Day 24), marked differences in the levels of multiple miRNAs can be detected in circulation by Day 60 in cattle. Retrospective analyses showed miR-26a levels to be increased in circulation as early as Day 8, sooner than previously reported in any species, suggesting a biological role for this miRNA in the very early events of pregnancy.

Diverse functions of HBEGF during pregnancy.

The establishment of pregnancy requires an intimate physical interaction and a molecular dialogue between the conceptus and the maternal reproductive tract that commences at implantation and continues until the placenta is formed and fully functional. Failure of the regulatory processes that ensure the fidelity of this relationship can precipitate a catastrophic pregnancy loss. One of the earliest identified molecular mediators of blastocyst implantation is heparin-binding epidermal growth factor (EGF)-like growth factor (HBEGF), which signals between the endometrium and implanting trophoblast cells to synchronize their corresponding developmental programs. HBEGF expression by trophoblast cells of the developing placenta appears to regulate extravillous differentiation and provide cytoprotection in a sometimes-hostile environment. This versatile member of the EGF signaling system will be examined in light of its associations with key events during early pregnancy.

To investigate the influence of granulocyte growth factor in uterine perfusion on the pregnancy outcome of patients with failure of embryo implantation for unknown reason. Then, 68 patients with failure of embryo implantation for unknown reason were enrolled in our hospital from November 2013 to February 2015, which were divided into observation group and control group by random (34 patients in each group). Patients in observation group received basic treatment for granulocyte growth factor in uterine perfusion on the next day, while patients in control group received basic treatment with placebo. Then, endometrial preparation, adverse reaction and pregnancy outcome of patients were compared between the two groups. Comparing the endometrial preparation and average endometrial thickness of patients in control group (9.87±2.12) with those in observation group [(9.87±2.12), there is no significant difference (P<0.05). After treatment, patients in both groups performed diabetes, hypertension and other pregnancy complications without difference of statistical significance (P<0.05). The embryo implantation rate and clinical pregnancy rate of patients in observation group were significantly higher than those in control group [(82.35%) and (44.12%) vs (52.94%) and (17.65%)]. Moreover, the live birth rate of patients in observation group performed significantly higher than that in control group [(41.18%) vs (14.71%)] with significant difference (P<0.05). By taking treatment of granulocyte growth factor, patients with failure of embryo implantation can effectively improve clinical pregnancy rate and embryo implantation rate without severe complication. Therefore, treatment of granlocyte growth factor can improve the pregnancy outcome of patients.

Implant failures can be divided into early and late according to the timing of failure. The purpose of this study was to characterize and compare both types. A retrospective cohort study was conducted in 194 patients (98 men and 96 women) who presented after dental implant failures during a 6-year period (2000 to 2006). The patient served as the unit of analysis. A history of at least 1 failed and removed dental implant served as the inclusion criterion. Patients were excluded from this study whenever their files had missing data. The collected data included a patient's characteristics, failure characteristics, and the anatomic status of the alveolar ridge after failure. Late failures were associated with moderate to severe bone loss, a larger number of failed implants per patient, a higher incidence in men, and mostly in posterior areas. Early failures were associated with minimal bone loss, occurred more in women, at a younger age, and in most cases the implants were intended to support single crowns. Meticulous follow-up is needed to reveal and treat failing or ailing implants. Once established as hopeless, they should be removed as soon as possible to prevent further bone loss.

The objectives of the present study were to evaluate the effect of per rectal amniotic sac palpation (ASP) for pregnancy diagnosis during the late embryonic period on pregnancy loss, calving rates, and abnormalities in newborn calves. A controlled, randomized, blocked, blind experiment containing 680 lactating pregnant dairy cows with a viable embryo diagnosed by transrectal ultrasonography was performed. Two dairy operation sites (farm A and farm B) were selected. At each farm, the cows were randomly divided into control (CON) and ASP groups. The CON group was not subjected to pregnancy diagnosis via per rectum palpation. The ASP examinations were performed by one experienced veterinarian between Days 34 and 45 after breeding. All cows were reevaluated by transrectal ultrasonography only between 2 and 4 weeks later. Two calving rates were calculated: calving rate 1 (cows that calved from the initial number of pregnant cows) and calving rate 2 (cows that calved from cows pregnant at reexamination). In farm A, the percentages of early pregnancy loss were 11.5% (19 of 165) and 13.2% (24 of 182) for the CON and the ASP groups, respectively (P = 0.64). In farm B, the percentage of early pregnancy loss was 11.2% (19 of 170) for the CON group and 8.8% (14 of 159; P = 0.48) for the ASP group. In farm A, the percentage of late pregnancy loss was 7.6% (11 of 145) for the CON group and 5.5% (8 of 155; P = 0.39) for the ASP group. In farm B, the percentage of late pregnancy loss was 3.7% (5 of 137) for the CON group and 6.3% (8 of 127; P = 0.32) for the ASP group. In farm A, early pregnancy loss was higher than late pregnancy loss (12.4% vs. 6.3%; P = 0.01), and in farm B, the same tendency was detected (10.0% vs. 4.9%, for early and late pregnancy loss, respectively; P = 0.02). In farm A, calving rate 1 was 81.2% (134 of 165) for the CON group and 80.8% (147 of 182; P = 0.92) for the ASP group. Calving rate 2 for the same groups was 92.4% (134 of 145) and 94.8% (147 of 155

We evaluated the influence of maternal self-reported habitual sleep duration during early pregnancy on blood pressure (BP) levels and risk of hypertensive disorders of pregnancy. Prospective cohort study. Clinic-based study. A cohort of 1,272 healthy, pregnant women. We abstracted maternal antenatal BP values from medical records and estimated mean BP differences across hours of sleep categories in regression models, using generalized estimating equations. Odds ratios (OR) and 95% confidence intervals (95% CIs) for pregnancy induced hypertension (PIH) and preeclampsia (PE) in relation to long and short sleep duration were estimated. Mean 1st and 2nd trimester systolic (S) and diastolic (D) BP values were similar among women reporting to be short sleepers (< or = 6 h) vs. women reporting to sleep 9 hours. However, both short and long sleep duration in early pregnancy were associated with increased mean 3rd trimester SBP and DBP. For example, mean 3rd trimester SBP was 3.72, and 2.43 mm Hg higher for women reporting < or = 6 h and 7-8 h sleep, respectively, compared with women reporting 9 h of sleep. Mean 3rd trimester SBP was 4.21 mm Hg higher for women reporting long sleep (> or = 10 h) vs. the reference group. Short and long sleep durations were associated with increased risks of PIH and PE. The ORs for very short (< 5 h) and long (> or = 10 h) sleepers were 9.52 (95% CI 1.83 to 49.40) and 2.45 (95% CI 0.74 to 8.15) for PE. Our findings are consistent with a larger literature that documents elevated blood pressure and increased risks of hypertension with short and long sleep duration.

Preeclampsia is a devastating complication of pregnancy characterized by late-gestation hypertension and proteinuria. Because the only definitive treatment is delivery of the fetus and placenta, preeclampsia contributes to increased morbidity and mortality of both mother and fetus. The BPH/5 mouse model, which spontaneously develops a syndrome strikingly similar to preeclampsia, displays excessive inflammation and suppression of inflammation improves pregnancy outcomes. During early pregnancy, decidual macrophages play an important role in promoting maternal tolerance to fetal antigens and regulating tissue remodeling, two functions that are critical for normal placental development. BPH/5 pregnancies are characterized by abnormal placentation; therefore, we hypothesized that macrophage localization and/or function is altered during early pregnancy at the site of placental formation (the decidua) compared to C57BL/6 controls. At early gestation time points, before the onset of maternal hypertension or proteinuria, there was a reduction in the number of macrophages in BPH/5 decidua and a concomitant increase in activated T cells compared to C57BL/6. BPH/5 decidua also exhibited decreased expression of the immunosuppressive cytokine, IL-10, and increased expression of pro-inflammatory, inducible nitric oxide synthase (iNOS). Together, these data suggest that a reduction in decidual macrophages during pregnancy is associated with immune activation in BPH/5 mice, inadequate placental development and may contribute to adverse pregnancy outcomes in this model.

The impact of father absence on early sexual activity and teenage pregnancy was investigated in longitudinal studies in the United States (N = 242) and New Zealand (N = 520), in which community samples of girls were followed prospectively from early in life (5 years) to approximately age 18. Greater exposure to father absence was strongly associated with elevated risk for early sexual activity and adolescent pregnancy. This elevated risk was either not explained (in the U.S. study) or only partly explained (in the New Zealand study) by familial, ecological, and personal disadvantages associated with father absence. After controlling for covariates, there was stronger and more consistent evidence of effects of father absence on early sexual activity and teenage pregnancy than on other behavioral or mental health problems or academic achievement Effects of father absence are discussed in terms of life-course adversity, evolutionary psychology, social learning, and behavior genetic models.

It is now well recognized that the presence of early pregnancy factor (EPF) can signify the occurrence of fertilization, continuation of pregnancy and the existence of a viable embryo. With this in view, a study was undertaken to observe the potential of EPF as a marker in assessing embryo viability in cases complicated with vaginal bleeding during early pregnancy. The results indicated that the sensitivity of EPF as a marker in predicting threatened or missed abortion was 78.9% and the specificity 95.6%. The positive predictive value was observed to be 93.8% and the negative predictive value 84.6%. Our studies have shown that since EPF is present in viable but absent in non-viable pregnancies, it could be a useful marker of prognostic value in threatened abortions.

We assessed environmental tobacco smoke (ETS) and examined its association with pregnancy discomforts. We used structured questionnaires to interview a convenience sample of 139 pregnant women (8-20 weeks of gestation) recruited from 2 hospitals in central Taiwan. We found that 84% of the participants experienced ETS exposure in their households, workplaces, and/or public areas. Bivariate analyses showed the severity of pregnancy discomforts in the participants exposed to a high level of ETS was higher than that in those exposed to a low level of ETS. We found the discomfort symptoms of thirst, heartburn, lower abdominal pain, frequent urination, and depression to be significantly associated with ETS exposure. There also was a dose-response relationship between ETS exposure and discomfort. In addition, the presence of at least 4 out of those 5 symptoms served as a signal for raising women's self-awareness to avoid ETS hazards. Our study provides empirical evidence of an adverse relationship between ETS exposure and early pregnancy discomforts. The exposure to ETS in pregnant women remains high, and health education programs targeting this population should enhance their self-awareness to the discomforts related to ETS exposure and prompt them to adopt prevention strategies.

, diversity, and evenness during pregnancy (P < .01). This change occurred between the first and second trimesters. Within-subject comparisons across pregnancy showed that preterm birth is associated with increased vaginal microbiome instability compared to term birth. No distinct taxa were associated with preterm birth. In a predominantly African-American population, a significant decrease of vaginal microbial community richness and diversity is associated with preterm birth. The timing of this suppression appears early in pregnancy, between the first and second trimesters, suggesting that early gestation may be an ecologically important time for events that ordain subsequent term and preterm birth outcomes.

To examine peak serum levels of the β-subunit of human chorionic gonadotropin (β-hCG) for prediction of early pregnancy outcomes among women with recurrent spontaneous abortion (RSA). In a retrospective study, the medical records of pregnant women with a history of RSA treated at Sun Yat-sen Memorial Hospital, China, between January 2011 and July 2013 were reviewed. Serum β-hCG had been measured twice weekly from 5 to 13weeks of pregnancy, and pregnancy was monitored by transvaginal ultrasonography to 13(+6)weeks. Optimal cutoff for peak β-hCG level was determined by receiver operator characteristic curve analysis and Youden index. Women were divided into four groups on the basis of optimal peak β-hCG cutoff and pregnancy outcome (pregnancy at 13weeks or spontaneous abortion). Peak β-hCG levels and length of pregnancy at this peak were examined. Overall, 1240 patients were included. The optimal cutoff value of peak β-hCG was 88 468IU/L, with a sensitivity, specificity, positive predictive value, and negative predictive value for successful pregnancy of 95.6%, 88.0%, 95.6%, and 89.0%, respectively. A faster rise in β-hCG, higher peak β-hCG, and longer pregnancy length at peak β-hCG were associated with successful early pregnancy. A cutoff value of serum β-hCG of 88 000IU/L could be used to predict early pregnancy outcomes for women with a history of RSA. Copyright © 2016. Published by Elsevier Ireland Ltd.

Many women continue drinking alcohol during pregnancy. This study aimed to describe educational differences in continued drinking in early and late pregnancy and to examine the contribution of psychological and physical factors to the explanation of educational differences. We examined 4,885 women enrolled in the Amsterdam Born Children and their Development study. Information on alcohol intake during pregnancy was based on self-reports at the 16th week of gestation and at 3 months postpartum. Only women who reported alcohol intake before pregnancy were included. Explanatory factors were alcohol intake before pregnancy, psychological problems, and physical problems. The risk of continued drinking in early pregnancy was increased in higher educated women (odds ratio [OR] = 1.41, 95% CI [1.25, 1.60]); in addition, in late pregnancy, higher educated women had an increased risk of restarting (OR = 1.67, 95% CI [1.37, 2.04]) and continuing drinking (OR = 1.77, 95% CI [1.36, 2.30]). The intensity of alcohol intake before pregnancy and all physical and psychological problems together explained 17.1% and 8.8% of the educational differences in continued drinking in early pregnancy, respectively. Higher educated women are more likely to continue drinking during pregnancy. The intensity of alcohol intake before pregnancy and physical and psychological problems contributed to the explanation of continued drinking. However, other factors may play a greater role, such as cultural factors and social norms.

To determine whether serum hyperglycosylated human chorionic gonadotropin (hhCG) measured as early as 9 days after egg retrieval can predict ongoing pregnancies after in vitro fertilization and fresh embryo transfer (IVF-ET). Cohort Academic assisted reproduction center. Consecutive patients undergoing IVF-ET INTERVENTION(S): Serum hhCG and hCG levels measured 9 (D9) and 16 (D16) days after egg retrieval Ongoing pregnancy beyond 9 weeks of gestation. Ongoing pregnancy (62 of 112 participants) was associated with higher D9 levels of hhCG and hCG. However, hhCG was detectable in all D9 OP samples, while hCG was detectable in only 22%. A D9 hhCG level of >110 pg/mL was 96% specific for an ongoing pregnancy, yielding a positive predictive value of 94%. Compared with the D9 hCG levels, hhCG was more sensitive and had a larger area under the curve (0.87 vs. 0.67, respectively). The diagnostic test characteristics were similar between the D16 hhCG and hCG levels. In patients undergoing assisted reproduction, a test to detect pregnancy early and predict outcomes is highly desirable, and hhCG is detectable in serum 9 days after egg retrieval IVF-ET cycles. In this early assessment, hhCG was superior to traditional hCG and highly predictive of ongoing pregnancies. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

To describe the prevalence of anemia and micronutrient deficiencies as well as their determinants in early pregnancy. Baseline data from a population-based randomized intervention trial. The study was conducted in Matlab, a sub-district in rural Bangladesh from 1 January to 31 December 2002. Pregnant women (n= 740) were enrolled in approximately week 14 in pregnancy. Data were collected using questionnaires, physical examinations and laboratory analyses of blood samples for concentrations of hemoglobin, ferritin, zinc, folate and vitamin B-12. Covariates associated with anemia and micronutrient deficiencies in bivariate analyses were evaluated in multivariate logistic regression models adjusting for potential confounders. Anemia was present in 28% of the women, 55% were zinc deficient, 46% were vitamin B-12 deficient and 18% were folate deficient. Anemia was not associated with iron deficiency but rather with vitamin B-12 deficiency. Infestation with Ascaris was highly prevalent (67%) and associated with both folate and vitamin B-12 deficiency. Anemia and micronutrient deficiencies all varied significantly with season. The high prevalences of zinc and vitamin B-12 deficiencies in early pregnancy are a concern, as it could lead to adverse pregnancy outcomes and increased health risks for both mother and child. The prevalence of iron deficiency was low, but as this was during early pregnancy, the women might develop iron deficiency and consequently iron deficiency anemia as the pregnancy progresses. © 2010 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2010 Nordic Federation of Societies of Obstetrics and Gynecology.

Cervical cancer is the second most common cancer diagnosed during pregnancy. Conservative management is possible, and different options should be discussed with patients. The main decision parameters are stage of disease, lymph node status, trimester of pregnancy and wishes of the patient. We reviewed our experience on cases of early-stage cervical cancer discovered during pregnancy and treated with different options of fertility-sparing management. Between 1990 and 2010, 5 patients with early-stage cervical cancer diagnosed during pregnancy were referred to our department for fertility-sparing treatment. The mean age at diagnosis was 28.6 years (range, 26-30 years). The stages of the tumors according to the International Federation of Gynecology and Obstetrics were IA2 in 2 women and IB1 in 3 women. The histological type was squamous carcinoma in 3 cases and adenocarcinoma in 2 cases. All patients willing to preserve their fertility were treated with vaginal radical trachelectomy (VRT) and pelvic lymph nodes dissection (PLN-D). Three procedures were performed in the first trimester: 1 patient was treated with medical abortion and then VRT and PLN-D, 2 patients were submitted to VRT and PLN-D during the first trimester, and 1 patient's case was complicated by spontaneous abortion. One patient was observed during the second trimester (20 weeks of gestation) and treated with VRT and PLN-D during pregnancy. Because this patient had pelvic lymph nodes positive for cancer, a cesarean delivery (CD) with radical hysterectomy and para-aortic lymph nodes dissection was performed followed by chemoradiotherapy.

Diagnosis of cervical cancer can occur during pregnancy.

The commercial introduction of three dimensional integrated circuits (3D-ICs) has been hindered by reliability challenges, such as stress related failures, resistivity changes, and unexplained early failures. In this paper, we discuss a new RF-based metrology, based on dielectric spectroscopy, for detecting and characterizing electrically active defects in fully integrated 3D devices. These defects are traceable to the chemistry of the insolation dielectrics used in the through silicon via (TSV) construction. We show that these defects may be responsible for some of the unexplained early reliability failures observed in TSV enabled 3D devices.

Preeclampsia is a devastating complication of pregnancy characterized by late-gestation hypertension and proteinuria. Because the only definitive treatment is delivery of the fetus and placenta, preeclampsia contributes to increased morbidity and mortality of both mother and fetus. The BPH/5 mouse model, which spontaneously develops a syndrome strikingly similar to preeclampsia, displays excessive inflammation and suppression of inflammation improves pregnancy outcomes. During early pregnancy, decidual macrophages play an important role in promoting maternal tolerance to fetal antigens and regulating tissue remodeling, two functions that are critical for normal placental development. BPH/5 pregnancies are characterized by abnormal placentation; therefore, we hypothesized that macrophage localization and/or function is altered during early pregnancy at the site of placental formation (the decidua) compared to C57BL/6 controls. At early gestation time points, before the onset of maternal hypertension or proteinuria, there was a reduction in the number of macrophages in BPH/5 decidua and a concomitant increase in activated T cells compared with C57BL/6. BPH/5 decidua also exhibited decreased expression of the immunosuppressive cytokine, IL-10, and increased expression of pro-inflammatory, inducible nitric oxide synthase. Together, these data suggest that a reduction in decidual macrophages during pregnancy is associated with immune activation in BPH/5 mice, inadequate placental development and may contribute to adverse pregnancy outcomes in this model.

It is generally believed that pregnancy is mediated by a Th2 response, which includes cytokines that promote placental growth and are involved in inducing tolerance to the foetus. If the balance between Th1/and Th2-mediated cytokines is disrupted, systemic and local changes could predispose the foetus to future disease. Therefore, a shift in the Th1/Th2 balance during pregnancy, possibly caused by underlying environmental factors, could be associated with post-partum autoimmune disease in the offspring. Based on this presumption, we used celiac disease as a model to investigate whether autoimmunity is triggered in the foetus during early pregnancy, observed as changes in the mother's cytokine profile. Ten cytokines were measured by electro-chemi-luminescent multiplex ELISA in serum samples obtained from mothers during early pregnancy. Cases included women with children who had developed verified celiac disease before the age of 5, who were compared with other women as matched controls. We observed that 7 out of 10 cytokine levels were significantly increased in our case mothers when compared to controls. Five of these belonged to what is generally known as a Th1-mediated response (TNFα, IFNγ, IL-2, IL-1β and IL-12) and two were Th2 cytokines (IL-13 and IL-10). However, the IL-10 cytokine is known to have features from both arms of the immune system. These results were confirmed in a logistic regression model where five out of the initial seven cytokines remained. This study suggests that increase in Th1 serum cytokines may be associated with celiac disease in offspring.

Cardiovascular Complications of Pregnancy

Pregnancy causes significant metabolic and hemodynamic changes in a woman’s physiology to allow for fetal growth. The inability to adapt to these changes might result in the development of hypertensive disorders of pregnancy (hypertension, preeclampsia or eclampsia), gestational diabetes and preterm birth. Contrary to previous beliefs these complications are not limited to the pregnancy period and may leave permanent vascular and metabolic damage. There is in addition, a direct association between these disorders and increased risk of future cardiovascular disease (CVD, including hypertension, ischemic heart disease, heart failure and stroke) and diabetes mellitus. Despite abundant evidence of this association, women who present with these complications of pregnancy do not receive adequate postpartum follow up and counseling regarding their increased risk of future CVD. The postpartum period in these women represents a unique opportunity to intervene with lifestyle modifications designed to reduce the development of premature cardiovascular complications. In some cases it allows early diagnosis and treatment of chronic hypertension or diabetes mellitus. The awareness of this relationship is growing in the medical community, especially among obstetricians and primary care physicians, who play a pivotal role in detecting these complications and assuring appropriate follow up.

What is the relationship between signs and symptoms of early pregnancy and pregnancy loss <20 weeks' gestation? Vaginal bleeding is associated with increased incidence of early pregnancy loss, with more severe bleeding and bleeding accompanied by lower abdominal cramping associated with greater incidence of loss; conversely, vomiting is associated with decreased incidence of early pregnancy loss, even in the setting of vaginal bleeding, while nausea alone is not. Two previous cohort studies with preconception enrollment suggested that bleeding is associated with loss while nausea is inversely associated with loss though these studies were limited by small study size and reporting after loss ascertainment. No prior preconception cohort study has examined multiple signs and symptoms in relation to pregnancy loss. Population-based preconception cohort of 501 couples discontinuing contraception to try for pregnancy in 16 counties in Michigan and Texas, USA. Participants were followed daily until positive home pregnancy test or 12 months of trying without an hCG pregnancy; women who became pregnant were followed daily from 2 to 7 weeks post-conception. Three hundred and forty-seven women had a positive home pregnancy test denoting hCG pregnancy. Three hundred and forty-one women remained after excluding ineligible pregnancies. Women recorded daily from 2 to 7 weeks post-conception their signs and symptoms, including vaginal bleeding (none, spotting, light, moderate and heavy), lower abdominal cramping, nausea and vomiting. Pregnancy losses were ascertained by a subsequent negative home pregnancy test, clinical confirmation or onset of menses, depending on gestational age at loss; time-to-loss was measured in days post-conception.

To examine the extent, nature and determinants of medication use in early pregnancy. We reviewed early pregnancy medication use, as reported to a midwife at the booking interview, in women delivering between 2000 and 2007 in a large maternity hospital in Dublin, Ireland (n = 61 252). Excluding folic acid, at least one medication was reported in 23 989 (39.2%) pregnancies. Over the counter (OTC) medications were reported in 11 970 (19.5%) pregnancies, illicit drugs or methadone in 545 (0.9%) and herbal medicines/supplements in 352 (0.58%). FDA category D and X medications were reported by 1532 (2.5%) and 1987 (3.2%) women. Asthma, depression and hypertension were among the most commonly reported chronic medical disorders. Medications with potential for foetal harm were reported by 86 (15.7%) women treated for depression and 68 (20%) women treated for hypertension. Factors associated with reporting the use of medications with potential for foetal harm included unplanned pregnancy (adjusted odds ratio [aOR] 1.31, 95% confidence interval [CI] 1.12-1.52), booking at less than 12 weeks gestation (aOR 1.83, 95%CI 1.58-2.13), being above 25 years of age, unemployed (aOR 2.58, 95%CI 2.03-3.29), nulliparous (aOR 1.41; 95%CI 1.22-1.63), single (aOR 1.28; 95%CI 1.06-1.54) or smoking during pregnancy (aOR 1.96, 95%CI 1.67-2.28). Women frequently report medication use in early pregnancy. Women and prescribers need to be aware of the lack of pregnancy safety data for many medications, and the need for pre-pregnancy planning. Prescribers should ensure that optimal medications are used when treating women of childbearing potential with chronic medical disorders.

The establishment of early pregnancy assessment units (EPAUs)/Gynaecology assessment units (GAUs) started more than 20 years ago in the UK to decrease hospital admissions of patients with early pregnancy problems. However, there are still wide variations in the quality of services provided by these units. The objective of this study was to create a method that can be used for continuous assessment of these units on a regular basis. We designed a dashboard covering all aspects of EPAU/GAU activities depending upon the early pregnancy unit association guidelines, and the department of health data and statistics. The EPAU/GAU dashboard has been used successfully in the early assessment pregnancy unit of Yeovil District hospital for few years and is still implemented until now. It is an excellent tool for continuous audit. It is a simple method that should be adopted by different EPAUs/GAUs for their objective assessment in order to improve the services provided by these units.

Tea, a common beverage, has been suggested to exhibit a number of health benefits. However, one of its active ingredients, caffeine, has been associated with preterm birth and low birthweight. We investigated whether tea consumption during early pregnancy is associated with an increased risk of preterm birth and abnormal fetal growth. A total of 8775 pregnant women were included from the Born in Guangzhou Cohort Study. Tea consumption (type, frequency, and strength) during their first trimester and social and demographic factors were obtained by way of questionnaires administered during pregnancy. Information on birth outcomes and complications during pregnancy was obtained from hospital medical records. Overall habitual tea drinking (≥1 serving/week) prevalence among pregnant women was low, at 16%. After adjustment for potential confounding factors (eg, maternal age, educational level, monthly income) tea drinking during early pregnancy was not associated with an increased risk of preterm birth or abnormal fetal growth (small or large for gestational age) (P>.05). We did not identify a consistent association between frequency of tea consumption or tea strength and adverse birth outcomes among Chinese pregnant women with low tea consumption. Our findings suggest that occasional tea drinking during pregnancy is not associated with increased risk of preterm birth or abnormal fetal growth. Given the high overall number of annual births in China, our findings have important public health significance. © 2017 Wiley Periodicals, Inc.

To evaluate the efficacy of a combined protocol of mifepristone and misoprostol in the management of early pregnancy failure (EPF) and the average time to expulsion of tissue and rate of side effects. Retrospective chart review of all consecutive women treated with primary medical management for EPF at our institution from 2006 to 2012. 168 patients were included in the present study. The overall success rate, defined as the absence of the need for surgical intervention, was 61 % and did not differ by calendar year. There was no difference in success rate grouped by diagnosis [intrauterine embryonic/fetal demise (IUED/IUFD) vs. anembryonic gestation; p = 0.30] or gestational age (<9 or ≥9 weeks; p = 0.48). The success rate varied significantly according to the required dose of misoprostol, ≤800 or >800 μg (68 vs. 50 %, p = 0.029). Of the possible predictive factors of success, only the dose of misoprostol required was a significant independent negative predictor. Mean and median time to tissue expulsion after the first dose of misoprostol were 8.4 and 5.5 h, respectively. The incidence of side effects was low with no blood transfusions required. The success rate in this study is markedly below published data. This can possibly be attributed to retrospective study design, allowing for physician subjectivity and patients' wishes in the absence of strict study requirements. The protocol was well tolerated with a paucity of side effects. We make suggestions for enhancing success rates in the clinical setting by optimizing medication protocols, establishing precise treatment guidelines and training physicians in the accurate interpretation of treatment outcomes.

Obstructive sleep apnea (OSA) or habitual snoring is known to be associated with impaired glucose tolerance and type 2 diabetes among both men and non-pregnant women. We examined the association of habitual snoring during early pregnancy with risk of impaired glucose tolerance (IGT) and gestational diabetes mellitus (GDM). A cohort of 1,579 women was interviewed during early pregnancy. We collected information about snoring frequency during early pregnancy. Results from screening and diagnostic tests for IGT and GDM were abstracted from medical records. Multivariate logistic regression models were fitted to estimate odds ratios (OR) and 95% confidence intervals (95% CI) of IGT and GDM associated with snoring in early pregnancy. Overall, women who snored "most or all of the time" had a 2.1-fold increased odds of IGT (OR 2.10; 95% CI 1.31-3.35) and a 2.5-fold increased odds of GDM (OR 2.50; 95% CI 1.34-4.67) as compared with women who never snored. Compared with lean women (pre-pregnancy body mass index (BMI) <25 kg/m2) who did not snore, lean snorers had a 2-fold increased odds of GDM (OR = 1.99, 95% CI: 1.07-3.68). The odds of GDM risk was particularly elevated among overweight women (BMI ≥ 25 kg/m2) who snored (OR = 5.01; 95% CI 2.71-9.26). However, there was no evidence of an interaction between overweight and snoring with GDM risk (p-value = 0.144). These findings, if confirmed, may have important implications for tailoring prenatal care for overweight pregnant women, and /or those with a history of habitual snoring in early pregnancy.

Are there any differences in the location and distance to the internal cervical ostium of the implantation site of the intrauterine gestation sacs, early pregnancy symptoms and pregnancy outcome at 12 weeks gestation between women with and without a previous Caesarean section (CS)? The presence of a CS scar affects the site of implantation, and the distance between implantation site and the scar is related to the risk of spontaneous abortion. WHAT IS KNOWN ALREADY?: Little is known about the impact of a CS scar on implantation other than the risk of Caesarean scar pregnancy (CSP). Furthermore, there is a paucity of information on how the proximity of implantation to the scar impacts on pregnancy outcome in the first trimester. A prospective cohort study conducted over 15 months in the early pregnancy unit of a London Teaching Hospital. Three hundred and eighty women underwent a transvaginal scan at 6-11 weeks of gestation. A total of 170 women had undergone ≥1 CS, and 210 women had no history of CS. The 380 women were recruited as consecutive non-selected cases. The relationship between the implanted sac and the CS scar was assessed by quantifiable measures and by subjective impression. Logistic regression analysis was used to determine the influence of the presence of a CS scar on pregnancy outcome. The final outcome of the study was the viability of the pregnancy at 12 weeks. Implantation was most frequently posterior (53%) in the CS group and fundal in the non-CS group (42%). Gestation sac implantation was 8.7 mm lower in the CS group (95% confidence interval (CI) 6.7-10.7, P < 0.0001). Presenting complaints differed in women with and without a previous CS (P = 0.0009). More frequent vaginal bleeding [73 versus 55%, difference -18, 95% CI (-27 to -8%] yet no clearly increased spontaneous abortion rates were noted in the CS group compared with the non-CS group (adjusted odds ratio = 1.1, 95% CI 0.6-1.9, P = 0.74). Subjective impression showed that in eight

A 24-year-old African American female (L.R.) with a history of smoking and gestational diabetes was diagnosed with Hodgkin lymphoma. She received multiple chemotherapies, including six cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), followed by radiation therapy to left inguinal areas for a total of 30.6 Gy in 17 fractions; she obtained complete remission. Two years later, L.R. had disease relapse in the mediastinum and received two cycles of ESHAP (etoposide, methylprednisolone, high-dose cytarabine, cisplatin) followed by etoposide and ifosfamide. She then received BEAM (carmustine, etoposide, cytarabine, and melphalan) as a conditioning regimen and underwent autologous bone marrow transplant. Her post-transplant course was complicated by cytomegalovirus antigenemia, aspergillus pneumonia, and congestive heart failure with left ventricular ejection fraction (LVEF) of 20%–25%. She was treated with an ACE inhibitor (lisinopril) and a beta-blocker (carvedilol) with improvement of her LVEF to 30%–35%. A follow-up chest x-ray showed an increase in the size of the anterior mediastinal adenopathy suspicious for relapse of lymphoma, and at the same time she was also found to be 5 weeks pregnant. Given her cardiomyopathy, significant obesity, poorly controlled diabetes, and cancer recurrence, L.R. was advised by her gynecologist that the pregnancy was very high risk and might not be viable. The oncologists advised her to terminate the pregnancy within the first trimester, as she needed salvage radiotherapy treatment to the mediastinum and chemotherapy treatments that might endanger the fetus. However, the patient decided to continue with the pregnancy. A multidisciplinary team—which included a cardiologist, oncologist, high-risk obstetrician, pharmacist, and nurse practitioner—was then involved to provide care during the pregnancy. A social worker was also solicited to help with home and financial issues because L.R. was a single mother with

Background Incisional hernia is the most common complication of abdominal surgery leading to reoperation. In the United States, 200,000 incisional hernia repairs are performed annually, often with significant morbidity. Obesity is increasing the risk of laparotomy wound failure. Methods We used a validated animal model of incisional hernia formation. We intentionally induced laparotomy wound failure in otherwise normal adult, male Sprague-Dawley rats. Radio-opaque, metal surgical clips served as markers for the use of x-ray images to follow the progress of laparotomy wound failure. We confirmed radiographic findings of the time course for mechanical laparotomy wound failure by necropsy. Results Noninvasive radiographic imaging predicts early laparotomy wound failure and incisional hernia formation. We confirmed both transverse and craniocaudad migration of radio-opaque markers at necropsy after 28 d that was uniformly associated with the clinical development of incisional hernias. Conclusions Early laparotomy wound failure is a primary mechanism for incisional hernia formation. A noninvasive radiographic method for studying laparotomy wound healing may help design clinical trials to prevent and treat this common general surgical complication. PMID:23036516

Early diagnosis of ectopic pregnancy (EP) is important due to life-threatening consequences in the first trimester of pregnancy. In this study we aimed to investigate the role of adenosine deaminase (ADA) activity in the prediction of EP. Forty-one patients with unruptured ectopic pregnancy comprised the case group and forty-two first trimester pregnant women with shown foetal heart beating in ultrasound comprised the control group. The mean ADA level in EP (10.9 ± 3.0 IU/L) was higher than that in control group (9.2 ± 3.6 IU/L) (p = 0.018). Receiver operating characteristics or ROC curve identified ADA value of 10.95 IU/L as optimal threshold for the prediction of EP with 56% sensitivity and 67% specificity. High ADA levels are valuable in the early diagnosis of EP. However more comprehensive studies are required.

Breastfeeding is beneficial for women and infants, and medical contraindications are rare. Prenatal and labor-related complications may hinder breastfeeding, but supportive hospital practices may encourage women who intend to breastfeed. We measured the relationship between having a complex pregnancy (entering pregnancy with hypertension, diabetes, or obesity) and early infant feeding, accounting for breastfeeding intentions and supportive hospital practices. We performed a retrospective analysis of data from a nationally-representative survey of women who gave birth in 2011-2012 in a US hospital (N = 2400). We used logistic regression to examine the relationship between pregnancy complexity and breastfeeding. Self-reported prepregnancy diabetes or hypertension, gestational diabetes, or obesity indicated a complex pregnancy. The outcome was feeding status 1 week postpartum; any breastfeeding was evaluated among women intending to breastfeed (N = 1990), and exclusive breastfeeding among women who intended to exclusively breastfeed (N = 1418). We also tested whether breastfeeding intentions or supportive hospital practices mediated the relationship between pregnancy complexity and infant feeding status. More than 33% of women had a complex pregnancy; these women had 30% lower odds of intending to breastfeed (AOR = 0.71; 95% CI, 0.52-0.98). Rates of intention to exclusively breastfeed were similar for women with and without complex pregnancies. Women who intended to breastfeed had similar rates of any breastfeeding 1 week postpartum regardless of pregnancy complexity, but complexity was associated with >30% lower odds of exclusive breastfeeding 1 week among women who intended to exclusively breastfeed (AOR = 0.68; 95% CI, 0.47-0.98). Supportive hospital practices were strongly associated with higher odds of any or exclusive breastfeeding 1 week postpartum (AOR = 4.03; 95% CI, 1.81-8.94; and AOR = 2.68; 95% CI, 1.70-4.23, respectively).

Embryos from undernourished and control donor ewes were transferred to undernourished and control recipient ewes. Progesterone and metabolic hormones were investigated in recipient ewes to determine their association with pregnancy success. Forty-five donor and 52 recipient Rasa Aragonesa ewes were fed 1.5 (control group; donor n=20; recipient n=25) or 0.5 (low group; donor n=25; recipient n=27) times the daily requirements for maintenance from the onset of estrous synchronization treatment to embryo collection and transfer. The embryos were collected 7days after the onset of estrus (day 0), and two good-quality embryos were transferred into each recipient ewe. The percentage of pregnant ewes on day 18 and 40 did not differ between the two groups, although the recipient undernourished ewes tended to have greater late embryonic mortality (from days 18-40) than the control recipient ewes (P=0.11). No effect of the nutrition of the donor was found. Recipients that became pregnant had a higher ovulation rate than non-pregnant ewes (P=0.02). Undernourished ewes had lower plasma insulin concentrations than control ewes (P=0.03), and those that suffered late embryo mortality (from days 18-40) tended to have lower insulin and progesterone concentrations than their counterparts that remained pregnant (P=0.06 and P=0.07, respectively). In this study, pregnancy in control and undernourished recipient ewes was not associated with the origin of the embryo (undernourished and control donors). In conclusion, failure to establish and maintain a pregnancy was associated with lower progesterone and insulin levels one week after estrus in recipient ewes. Copyright © 2016 Elsevier B.V.

Lactating Holstein cows (n = 141) were synchronized to receive their first timed artificial insemination (TAI). Blood and milk samples were collected 25 and 32 d after TAI, and pregnancy status was determined 32 d after TAI using transrectal ultrasonography. Cows diagnosed pregnant with singletons (n = 48) continued the experiment in which blood and milk samples were collected and pregnancy status was assessed weekly using transrectal ultrasonography from 39 to 102 d after TAI. Plasma and milk samples were assayed for pregnancy-associated glycoprotein (PAG) levels using commercial ELISA kits. Compared to ultrasonography, accuracy was 92% for the plasma PAG ELISA test and 89% for the milk PAG ELISA test 32 d after TAI. Plasma and milk PAG levels for pregnant cows increased from 25 d to an early peak 32 d after TAI. Plasma and milk PAG levels then decreased from 32 d after TAI to a nadir from 53 to 60 d after TAI for the plasma PAG assay and from 46 to 67 d after TAI for the milk PAG assay followed by an increase from 74 to 102 d after TAI. Overall, plasma PAG levels were approximately 2-fold greater compared with milk PAG levels, and primiparous cows had greater PAG levels in plasma and milk compared with multiparous cows. The incidence of pregnancy loss from 32 to 102 d after TAI based on ultrasonography was 13% for cows diagnosed with singleton pregnancies, and plasma and milk PAG levels decreased to nonpregnant levels within 7 to 14 d after pregnancy loss. Both plasma and milk PAG levels were negatively correlated with milk production for both primiparous and multiparous cows. We conclude that stage of gestation, parity, pregnancy loss, and milk production were associated with plasma and milk PAG levels after TAI similarly. Based on plasma and milk PAG profiles, the optimal time to conduct a first pregnancy diagnosis is around 32 d after AI, coinciding with an early peak in PAG levels. Because of the occurrence of pregnancy loss, all pregnant cows should be

To evaluate the role of maternal factors, biomarkers, and uterine-artery Doppler in the prediction of hypertension during pregnancy. A prospective cohort study was performed between December 2012 and November 2014. All singleton pregnancies between 11 weeks and 13 weeks, 6 days of pregnancy were included. Patients had their body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters), mean arterial pressure, uterine-artery Doppler pulsatility index, and pregnancy-associated plasma protein A (PAPP-A) and free β-human chorionic gonadotropin levels recorded. Any patients diagnosed with hypertension during follow-up were assigned to the case cohort; all other patients were assigned to the control group. Hypertension during pregnancy was observed in 198 (9.7%) of 2042 patients that attended follow-up. The mean BMI, mean arterial pressure, uterine-artery Doppler pulsatility index, and the PAPP-A level at study enrollment were all significantly correlated with the later development of hypertension (P<0.001 for all variables). The combined sensitivity, specificity, positive predictive value, and negative predictive value of using the investigated parameters to predict hypertension was 76%, 80%, 31%, and 93%, respectively. Patient BMI, mean arterial pressure, PAPP-A, and pulsatility index were found to be effective predictors of hypertension during pregnancy. Combining these predictors may be beneficial in selecting individuals for close monitoring and early intervention during pregnancy.

BACKGROUND Antihistamines are commonly used during pregnancy. There is little evidence that they have teratogenic effects, but there are knowledge gaps with respect to newer products, as well as the relationship between specific antihistamines and specific birth defects. METHODS Using the National Birth Defects Prevention Study (1997-2003), the authors examined associations between maternal use of 14 antihistamines during early pregnancy and 26 isolated major birth defects. A Bayesian analysis incorporating prior knowledge about the relationships between the antihistamines, birth defects, and measured covariates was conducted. RESULTS Of the 364 associations investigated, 24 had 95% posterior intervals excluding 1.0. All 24 associations were positive; 23 associations were of weak to moderate magnitude (posterior odds ratio [OR] < 3.0) and one was strong (OR > 6.0) but very imprecise. Of the 24 associations, 20 were with non-cardiac defects. Eight associations involved the antihistamine diphenhydramine. CONCLUSIONS The results of this study generally were consistent with no association between birth defects and antihistamine use during early pregnancy. Several of the findings might warrant further investigation, although the observed elevated associations should be interpreted in the context of the number of associations investigated and the analysis of retrospective, self-reported data.

The replacement of lost teeth with dental implants is a widespread treatment whose associated problems are also frequently encountered. Nevertheless, the factors associated with early implant failure have not been well documented. Further analyses of the factors influencing osseointegration establishment are required to maximize the predictability of the procedure and minimize implant failures. The purpose of this retrospective clinical study was to explore the association between possible risk factors and early implant failure. This retrospective clinical study evaluated 142 participants who received 276 external connection BTI implants between 2007 and 2011. Participant variables (age, sex, systemic disease, tobacco use, alcohol consumption, bruxism, and degree of periodontal disease), implant variables (type of edentulism, localization, area, diameter, length, and bone quality), intervention variables (expansion mechanisms, sinus augmentation techniques, bone regeneration, and implant insertion), and postoperative variables (presence of pain/inflammation at 1 week postsurgery) were studied. A multilevel logistic regression model (mixed effects-type model) was used to determine the influence of variables on early implant failure. Early implant failure was significantly associated with the male sex (P=.001), severe periodontal disease (P=.005), short implants (P=.001), expansion technique (P=.002), and postoperative pain/inflammation at 1 week postsurgery (P<.001). Early dental implant failure is more frequent in men and in individuals with severe periodontal disease, short implants, pain/inflammation at 1 week postsurgery, or bone expansion treatment.

Abnormal liver function tests are common in pregnancy; however, liver failure is rare. Pregnancy is a catabolic state that can precipitate illness in patients with underlying metabolic disorders. A 19-year-old woman presented at 14 weeks of gestation with an alanine transaminase of 2,252 international units/L (less than 30), an international normalized ratio of 6.9 (0.9-1.2), and an ammonia of 58 micromole/L (11-51 micromole/L). No cause was identified on routine investigations including liver biopsy. Biochemical and clinical deterioration prompted investigation for a metabolic disorder. Urinary orotic acid was elevated, consistent with the urea cycle disorder type 1 citrullinemia. Appropriate management (arginine supplementation and dietary protein restriction) led to rapid improvement and later delivery of a healthy neonate. This is an unusual presentation that reminds us of the importance of considering metabolic disorders during the catabolic stress of pregnancy.

Gestational weight gain (GWG) is associated with infant birth weight and childhood obesity; however, the patterns of GWG on infant birth weight are poorly understood. This analysis in 16,218 mother-child dyads from Tianjin, China, determined the risk of infant size at birth according to GWG occurring throughout the first and second trimester (early GWG) or during the third trimester (late GWG), according to maternal prepregnancy BMI and the 2009 Institute of Medicine recommendations. Excessive GWG in early and late pregnancy had an increased risk for large-for-gestational-age (LGA) infants (odds ratio [OR]: 2.4; 95% confidence interval [CI]: 1.5-4.0, P < 0.001). Regardless of prepregnancy BMI, excessive GWG early in pregnancy (< 24 weeks) was associated with an increased risk of LGA infants (OR: 2.5; 95% CI: 2.1-3.1, P < 0.001), and inadequate early GWG was associated with a higher risk of small-for-gestational-age (SGA) infants (OR: 1.4; 95% CI: 1.2-1.7, P < 0.001). The pattern of GWG early in pregnancy, regardless of GWG later in pregnancy, had the greatest impact on infant size at birth. Interventions initiated early in pregnancy may facilitate better adherence to the GWG guidelines and minimize the risk of LGA and SGA infants, a potential precursor for childhood obesity. © 2017 The Obesity Society.

The effect of exposure to hypergravity on pregnant rat dams, pregnancy outcome and early neonatal development

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

Recurrent pregnancy loss (RPL) is defined by two or more failed clinical pregnancies. Three to four percent of the couples with RPL have chromosomal aberrations (CA) in at least one partner. The parent's structural chromosomal abnormalities may cause an unbalanced karyotype in the conceptus which could lead to implantation failure, early or late pregnancy loss, or delivery of a child with severe physical and/or mental disabilities. To compare live birth rates of couples with CA to couples with normal karyotypes and to investigate medical and obstetric characteristics and pregnancy outcomes of couples with CA and RPL who attend an RPL clinic at a tertiary hospital. A retrospective cohort study, including 349 patients with two or more consecutive pregnancy losses. The study group consisted of 52 patients with CA, and the control group consisted of 297 couples with normal karyotype. All patients were evaluated and treated in the RPL clinic at Soroka University Medical Center and had at least one subsequent spontaneous pregnancy. The demographic and clinical characteristics were not found to be statistically different between the two groups. The group of carriers of CA had 28/52 (53.8%) live births in their index pregnancy vs. the normal 202/297 (68%) (P=0.067, CI 95%) in the control group. No statistically significant etiology was found between the study group and the control group. A statistically significant difference in live birth rates was found when comparing the total amount of pregnancies [index pregnancy (IP)+post index pregnancy (PIP)] between the study group and the control group (54.16% vs. 67.82%, respectively, P=0.0328). Patients with RPL and CA who have spontaneous pregnancies, have a good prognosis (63.4%) of a successful pregnancy with at least one of the pregnancies (index or post index) resulting in a live birth.

Recently proposed international guidelines for screening for gestational diabetes mellitus (GDM) recommend additional screening in early pregnancy for sub-populations at a high risk of type 2 diabetes mellitus (T2DM), such as indigenous women. However, there are criteria that should be met to ensure the benefits outweigh the risks of population-based screening. This review examines the published evidence for early screening for indigenous women as related to these criteria. Any publications were included that referred to diabetes in pregnancy among indigenous women in Australia, Canada, New Zealand and the United States (n = 145). The risk of bias was appraised. There is sufficient evidence describing the epidemiology of diabetes in pregnancy, demonstrating that it imposes a significant disease burden on indigenous women and their infants at birth and across the lifecourse (n = 120 studies). Women with pre-existing T2DM have a higher risk than women who develop GDM during pregnancy. However, there was insufficient evidence to address the remaining five criteria, including the following: understanding current screening practice and rates (n = 7); acceptability of GDM screening (n = 0); efficacy and cost of screening for GDM (n = 3); availability of effective treatment after diagnosis (n = 6); and effective systems for follow-up after pregnancy (n = 5). Given the impact of diabetes in pregnancy, particularly undiagnosed T2DM, GDM screening in early pregnancy offers potential benefits for indigenous women. However, researchers, policy makers and clinicians must work together with communities to develop effective strategies for implementation and minimizing the potential risks. Evidence of effective strategies for primary prevention, GDM treatment and follow-up after pregnancy are urgently needed. Copyright © 2013 John Wiley & Sons, Ltd. PMID:23315909

The role of magnesium and thyroid function in early pregnancy after in-vitro fertilization (IVF): New aspects in endocrine physiology.

PubMed

Stuefer, Sibilla; Moncayo, Helga; Moncayo, Roy

2015-06-01

The initiation of a pregnancy is a process that requires adequate energetic support. Recent observations at our Institution suggest a central role of magnesium in this situation. The aim of this study was to evaluate magnesium, zinc, selenium and thyroid function as well as anti-Müllerian hormone in early pregnancy following in-vitro fertilization as compared to spontaneous successful pregnancies. A successful outcome of pregnancy after IVF treatment was associated with 2 parameters: higher levels of anti-Müllerian hormone as well as higher levels of magnesium in the pre-stimulation blood sample. These two parameters, however, showed no correlation. Spontaneous pregnancies as well as pregnancies after IVF show a fall of magnesium levels at 2-3 weeks of gestation. This drop of magnesium concentration is larger following IVF as compared to spontaneous pregnancies. Parallel to these changes TSH levels showed an increase in early IVF-pregnancy. At this time point we also observed a positive correlation between fT4 and TSH. This was not observed in spontaneous pregnancies. Thyroid antibodies showed no correlation to outcomes. In connection with the initiation of pregnancy following ovarian stimulation dynamic changes of magnesium and TSH levels can be observed. A positive correlation was found between fT4 and TSH in IVF pregnancies. In spontaneous pregnancies smaller increases of TSH levels are related to higher magnesium levels. We propose that magnesium plays a role in early pregnancy as well as in pregnancy success independently from anti-Müllerian hormone. Neither thyroid hormones nor thyroid antibodies were related to outcome.

Acute Respiratory Failure patients experience significant muscle weakness which contributes to prolonged hospitalization and functional impairments post-hospital discharge. Based on our previous work, we hypothesize that an exercise intervention initiated early in the intensive care unit aimed at improving skeletal muscle strength could decrease hospital stay and attenuate the deconditioning and skeletal muscle weakness experienced by these patients. Summary Early exercise has the potential to decrease hospital length of stay and improve function in Acute Respiratory Failure patients. PMID:23873130

We sought to evaluate the global success rate of intramuscular methotrexate for the treatment of ectopic pregnancy, identify factors predictive of treatment success or failure, and study methotrexate tolerability in a large patient cohort. For this single-center retrospective observational study, we retrieved the records of all women who had a clinically or echographically confirmed ectopic pregnancy with a Fernandez score <13 and who were treated according to a 1mg/kg intramuscular single-dose methotrexate protocol. Medical treatment failure was defined by an obligation to proceed to laparoscopy. Needing a second injection was not considered to be medical treatment failure. Between February 2008 and November 2013 (69 months), 400 women received methotrexate for ectopic pregnancy. The medical treatment protocol was effective for 314 patients, i.e., an overall success rate of 78.5%. A single methotrexate dose was sufficient for 63.5% of the women and a second dose was successful for 73.2% of the remaining women. The medical treatment success rate fell as initial hCG levels climbed. The main factors associated with methotrexate failure included day (D) 0, D4 and D7 hCG levels, pretherapeutic blood progesterone, hematosalpinx at D0 and pain at D7. Early favorable kinetics of hCG levels was predictive of success. Methotrexate treatment was successful in 90% of women who had D0 hCG <1000IU/l. Methotrexate tolerability was good, with only 9% of the women reporting non-severe adverse effects. The fertility rate with delivery after medical treatment for ectopic pregnancy was 80.7%. In this study, we showed that an initial hCG value <1000IU/l and favorable early HCG kinetics were predictive factors for the successful medical treatment of ectopic pregnancy by methotrexate, and hematosalpinx and pretherapeutic blood progesterone >5ng/ml at diagnosis were predictive of its failure. We also confirmed good tolerability for single-dose methotrexate protocols. Copyright �

The presence of early pregnancy factor (EPF) has been repeatedly confirmed as indispensable to successful pregnancy. However, there is as yet little reported about how surgical abortion would affect the EPF activity, owing to the induced embryo loss. The aim of this study was to pursue this among a large number of patients available in the People's Republic of China. Sera from aborters were collected before surgical abortion and again on the 3rd, 5th and 7th day after treatment. EPF activity was detected by rosette inhibition assay. Before surgical abortion, the mean level of EPF in pregnancy sera was about the same as that of the positive control. After surgical abortion, the EPF level declined rapidly for the first 3 days and then dropped gradually within the negative control range after 5-7 days. Quantitative study of EPF activity along temporal dimensions (duration) due to surgical abortion further promotes the efficiency to take EPF activity and its rate of change as truly index for monitoring embryonic care and development of normal pregnancy.

Endometrial scratch injury (ESI) has been recently proposed to enhance the implantation rate in assisted reproductive technology cycles. The present study was conducted to determine the effect of ESI on pregnancy rate in women with intrauterine insemination (IUI) failure. This prospective randomized controlled study was carried out in Imam-Khomeini Hospital and Royan Institute, Tehran, during a 12-month period from January 2013 to January 2014. After assessment, 169 patients who had IUI failure twice or more (no chemical or clinical pregnancy) with normal uterine anatomy and hysterosalpingography, were enrolled. They were randomly assigned into two groups. In the experimental group, all patients underwent ESI at day 8 or 9 of stimulation phase in the present IUI cycle, whereas no intervention was performed on the control group. IUI outcome was then compared between the two groups. A total of 150 patients completed the IUI cycle during the study. The chemical pregnancy rate was 10.7% and 2.7% in the experimental and control groups, respectively, without significant difference (P = 0.09). Also no significant differences were detected in terms of clinical pregnancy and miscarriage rates between the two groups (P > 0.05). No significant beneficial effect of ESI on fertility outcome in patients with repeated IUI failure was detected when it was carried out on day 8 or 9 of the same IUI stimulation cycle. Also, however, no negative impact secondary to ESI was observed. Therefore, confirmation or refutation of this hypothesis requires further studies with a larger sample size.

To determine whether there were "quality gaps" in the provision of care during pregnancies that resulted in a perinatal death due to congenital abnormality. Perinatal deaths from congenital cardiovascular, central nervous system or chromosomal abnormality in 2010 were identified retrospectively. Data were extracted by retrospective clinical note review and obtained by independent review of ultrasound scans. There were 137 perinatal deaths due to a congenital cardiovascular (35), central nervous system (29) or chromosomal abnormality (73). First contact with a health professional during pregnancy was predominantly with a general practitioner. First contact occurred within 14 weeks in 85% of pregnancies and there was often a significant delay before booking. Folate supplements were taken by 7% pre-conceptually and 54% of women in the antenatal period. There were 20 perinatal deaths from neural tube defects that could potentially have been prevented through the use of pre-conceptual folate. Antenatal screening was offered to 75% of the women who presented prior to 20 weeks and 84% of these undertook at least one of the available antenatal screening tests. Review of ultrasound images found five abnormalities could have been detected earlier. Delay in booking or failure to offer screening early were the most common reasons for delay in diagnosis of screen detectable abnormalities. The preventative value and timing of (pre-conceptual) folate needs emphasis.

According to the WHO, hypertension is one of the major causes of death worldwide. It leads to a number of severe complications. Diastolic heart failure, that is heart failure with preserved ejection fraction (HFPEF), is especially common. New, but simple, indices for the early detection of patients who have not yet developed complications or are in their early developmental stages are still searched for. The aim of this study is to examine the correlation between pulse wave velocity (PWV) and markers of diastolic heart failure (DHF) assessed in echocardiography in patients with hypertension and no symptoms of heart failure. The study was comprised of 65 patients with treated hypertension. Patients with symptoms of heart failure, those with diabetes and smokers were excluded. Arterial stiffness was measured with the Mobil-O-Graph NG PWA. Pulse wave velocity (PWV) was estimated. The following markers of diastolic heart failure were assessed in the echocardiographic examination: E/A ratio - the ratio of the early (E) to late (A) ventricular filling velocities, DT - decceleration time, E/E' - the ratio of mitral peak velocity of early filling (E) to early diastolic mitral annular velocity E' in tissue Doppler echocardiography. PWV was statistically significantly higher in the DHF group. In the group of patients with heart failure, the average E/A ratio was significantly lower as compared to the group with no heart failure. Oscillometric measurement of pulse wave velocity is non-invasive, lasts a few minutes and does not require the presence of a specialist. It allows for an early detection of patients at risk of diastolic heart failure even within the conditions of primary health care.

The purpose of this study was to investigate associations of maternal binge drinking in early and late pregnancy with child behavioural and emotional development at age seven. It was hypothesised that late exposure is associated with more negative outcomes than early exposure. Differences were expected on the continuous outcome measures, but not on above cutoff scale scores. Data were derived from the Danish National Birth Cohort. Three exposure groups were defined according to binge drinking from three interviews regarding binge episodes in early, middle and late pregnancy. A 'no binge' group included women with no binge episodes reported in any of the interviews, the 'early bingers' reported episodes in the first interview only, and the 'late bingers' in the last part of pregnancy only. The outcome measure was the Strengths and Difficulties Questionnaire (SDQ) used as continuous externalising/internalising scores and above cutoff hyperactivity/inattention, conduct, emotional and peer problems scores. Only women with full information concerning binge drinking from the three interviews, together with full-scale SDQ information on their children at age seven and being term-born, were included in the study (N = 37,315). After adjustment for maternal education, psychiatric diagnoses, age and smoking, children exposed to binge drinking in early and late pregnancy had significantly higher mean externalizing scores at age seven than unexposed children, an effect albeit much less for early binge drinking (relative change in mean 1.02, CI 1.00-1.05) than for late binge drinking (relative change in mean 1.21, CI 1.04-1.42). No associations were observed for any of the above cutoff outcomes. Exposure to binge drinking in early and late pregnancy is associated with elevated externalising scores, particularly so in late pregnancy. No increased risk for any of the above cutoff scale scores was observed.

Could anterior papillary muscle partial necrosis explain early mitral valve repair failure?

2014-09-01

Standardized techniques of mitral valve repair (MVR) have recently witnessed the introduction of a 'respect rather than resect' concept, the strategy of which involves the use of artificial chordae. MVR displays several advantages over mitral valve replacement in degenerative mitral regurgitation (MR), but the risk of reoperation for MVR failure must be taken into account. Different mechanisms could be advocated as the leading cause of MVR failure; procedure-related mechanisms are usually involved in early MVR failure, while valve-related mechanisms are common in late failure. Here, the case is reported of an early failure of MVR using artificial chordae that could be explained by an unusual procedure-related mechanism, namely anterior papillary muscle necrosis. MVR failure is a well-known complication after surgical repair of degenerative MR, but anterior papillary muscle partial necrosis might also be considered a possible mechanism of procedure-related MVR failure, especially when considering the increasing use of artificial chordae. Owing to the encouraging results obtained, mitral valve re-repair might be considered a viable solution, but must be selected after only a meticulous evaluation of the underlying mechanism of MVR failure.

Burden of malaria in early pregnancy: a neglected problem?

2015-02-15

According to the current World Health Organization guidelines, the drug prevention of malaria during pregnancy does not adequately cover the first trimester of gestation in high-transmission areas. Although the pathophysiological mechanisms of early infections are not completely understood yet, a review of the most recent studies on the topic suggests that their consequences are serious in terms of maternal anemia and low birth weight. Consequently, there is a need to focus on the awareness of women in a period hard to access, to develop safe drugs to be used in the first trimester, and to consider preconceptional interventions in teenage girls, such as a new malaria vaccine to be used in pregnancy. © The Author 2014.

2005-08-01

Hyperthyroidism does not influence procreation ability significantly, but very often causes complications of the course of pregnancy and increases neonatal morbidity and mortality in newborns. Nausea and vomiting in the first trimester of pregnancy are very common complaints in these patients. The aim of the study was to prove, that assessment of the thyroid hormones in every vomiting woman in the first trimester allows to start the proper treatment of hyperthyreosis as early as possible and improves the prognosis. Authors analyzed 22 pregnant women treated for vomiting during the first trimester in the Department of Obstetrics and 5 women treated in the Outpatient Clinic. In none of them hormonal dysfunction was diagnosed before pregnancy. In 21 patients free thyroxine (fT4) in serum was assessed. In 8 cases (38%) hyperthyreosis was diagnosed. Except the routine anti vomiting treatment, they received a beta-blocker 30 mg per day. It allowed to avoid hospitalization in three pregnant women treated in the outpatient clinic. Two patients, who had earlier two spontaneous abortions, delivered healthy babies. 1. The beta-blocker in treatment gives very good results and allows to avoid hospitalization in patients with hyperthyroidism and hyper emesis gravidarum. 2. In some patients vomiting may be the only symptom of sub clinical hyperthyroidism in early pregnancy. Assessment of the thyroid hormones levels and adequate treatment may give these women a chance for a healthy child.

The potential effects of binge drinking during pregnancy on child motor function have only been assessed in a few, small studies. We aimed to examine the effects of binge alcohol consumption during early pregnancy, including number of binge episodes and timing of binge drinking, on child motor function at age 5. We performed a prospective follow-up study of 678 women and their children sampled from the Danish National Birth Cohort based on maternal alcohol consumption during pregnancy. At 5 years of age, the children were tested with the Movement Assessment Battery for Children. Parental education, maternal IQ, prenatal maternal smoking, the child's age at testing, sex of child, and tester were considered core confounders, while the full model also controlled for prenatal maternal average alcohol intake, maternal age and prepregnancy body mass index, parity, home environment, postnatal parental smoking, health status, participation in organized sport, and indicators for hearing and vision impairment. There were no systematic or significant differences in motor function between children of mothers reporting isolated episodes of binge drinking and children of mothers with no binge episodes. No association was observed with respect to the number of binge episodes (maximum of 12) and timing of binge drinking. In this study, we found no systematic association between isolated episodes of binge drinking during early pregnancy and child motor function at age 5.

Abstract Objective Bacterial vaginosis (BV) is associated with preterm delivery, but there is little evidence that treatment improves pregnancy outcomes. We examined whether oral or vaginal metronidazole treatment for BV in early pregnancy was more effective in restoring the normal vaginal environment. Methods This was a randomized controlled trial comparing oral and intravaginal metronidazole for treatment of BV in early pregnancy (<20 weeks). Vaginal samples collected at baseline and 4 weeks after treatment were evaluated using gram stain, culture, colorimetric detection of sialidase, and immunoassay for measurement of proinflammatory cytokines interleukins-1β, -6, -8 (IL-1β, IL-6, IL-8) and secretory leukocyte protease inhibitor (SLPI). We compared the effect of treatment between groups (using chi-square and t test) and within individuals (McNemar's test). Results Of 126 subjects, 108 (86%) completed follow-up (55 oral, 53 intravaginal). Of the study population, 34% achieved therapeutic cure, and this was not different between treatment groups. BV-associated bacteria were significantly reduced in both groups, but few subjects regained colonization with protective lactobacilli. Among women who achieved therapeutic cure, the level of IL-1β dropped significantly (p < 0.001) and SLPI increased (p = 0.003). More women in the vaginal treatment group had undetectable sialidase after treatment (p = 0.013). Conclusions Treatment with oral or intravaginal metronidazole in early pregnancy reduced colonization with BV-associated bacteria but was not effective in achieving therapeutic cure or in restoring healthy vaginal lactobacilli.

Untreated and subclinical hypothyroidism (SCH) has been associated with adverse pregnancy complications such as increased risk of miscarriage, hypertension, preeclampsia, and preterm delivery. However, in Sweden, screening for thyroid dysfunction during pregnancy is only recommended for women with a high risk of thyroid disease. Therefore, the aim of this study was to determine the incidence of clinical and SCH in women in the first trimester of pregnancy. In this prospective study, 1298 pregnant women were divided into three groups: one unselected general screening group (n = 611), one low-risk group comprising women without risk factors for thyroid disorder (n = 511), and one high-risk group comprising women with an inheritance or suspicion of thyroid disease or undergoing treatment for thyroid disease (n = 88). Serum was obtained up to gestational week 13, and thyrotropin (TSH) was analyzed. The incidences of thyroid dysfunction in the three screening groups were 9.8% in the general screening group, 9.6% in the low-risk group, and 10.2%, p = 0.948, in the high-risk group. In the women with known hypothyroidism on levothyroxine treatment, 50.6% had serum TSH levels above 2.0 mIU/L. High-risk screening is not useful in predicting which women are at risk of thyroid disease in early pregnancy since ∼10% of women with SCH or hypothyroidism could not be diagnosed in this way.

The relative validity of food frequency questionnaires for estimating long-chain polyunsaturated fatty acid (LC-PUFA) intake among pregnant Japanese women is currently unclear. The aim of this study was to verify the external validity of a food frequency questionnaire, originally developed for non-pregnant adults, to assess the dietary intake of LC-PUFA using dietary records and serum phospholipid levels among Japanese women in early and late pregnancy. A validation study involving 188 participants in early pregnancy and 169 participants in late pregnancy was conducted. Intake LC-PUFA was estimated using a food frequency questionnaire and evaluated using a 3-day dietary record and serum phospholipid concentrations in both early and late pregnancy. The food frequency questionnaire provided estimates of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) intake with higher precision than dietary records in both early and late pregnancy. Significant correlations were observed for LC-PUFA intake estimated using dietary records in both early and late pregnancy, particularly for EPA and DHA (correlation coefficients ranged from 0.34 to 0.40, p < 0.0001). Similarly, high correlations for EPA and DHA in serum phospholipid composition were also observed in both early and late pregnancy (correlation coefficients ranged 0.27 to 0.34, p < 0.0001). Our findings suggest that the food frequency questionnaire, which was originally designed for non-pregnant adults and was evaluated in this study against dietary records and biological markers, has good validity for assessing LC-PUFA intake, especially EPA and DHA intake, among Japanese women in early and late pregnancy.

To analyse drug use in early pregnancy with special focus on socio-demographic factors associated with psychotropic and analgesic drug use. Cross-sectional study. A total of 1765 women were invited via their local health care centres, and 1111 participated at 11-16 weeks of pregnancy by filling out a postal questionnaire concerning socio-demographic and obstetric background, stressful life events, and drug use. Drug use prior to and early on in pregnancy, socio-demographic factors, smoking, and adverse life events were investigated. Drug categories screened for were psychotropics (collective term for antidepressants, relaxants, and sleep medication), analgesics, hormones, nicotine, vitamins/minerals, and homeopathic medicine. Drug use from the aforementioned drug categories, excluding vitamins/minerals and homeopathic medicine, was reduced by 18% during early pregnancy, compared with six months prior to conception (49% vs. 60%). Psychotropic drug use during early pregnancy was associated with elementary maternal education (p < 0.5), being unemployed (p < 0.001), being single/divorced/separated (p < 0.01), smoking prior to or during pregnancy (p < 0.01), forced to change job/move house (p < 0.001), and psychotropic drug use six months prior to pregnancy (p < 0.001). No items on the stressful life events scale were associated with increased analgesic use, which increased only with multiparity. Use of analgesics and psychotropic drugs seems common in pregnancy. Our results indicate that lack of a support network, stressful life events, and lower status in society may predispose women to more drug use. GPs and midwives responsible for maternity care could take this into account when evaluating risk and gain for women and foetuses in the primary care setting.

The authors introduced 3 ml of 2-3% Bromo-Geraminum (BG) solution into the uterine cavities to induce abortion in 356 early pregnant women from March 1979 through June 1980. The success rate in the termination of early pregnancy was 80.1% and even 96.5% in those who had been pregnant for less than 5 weeks. The mean abortion time was 40.9 porn 19.7 hours. It was noticed that the blood HCG level dropped dramatically after introducing into the uterine cavity. It has been demonstrated experimentally and clinically that this method is effective, safe, simple, and inexpensive and that the normal menstrual cycle recovers very soon without side effects.

OBJECTIVE Preeclampsia is a multisystem disease classically defined on the basis of hypertension and proteinuria. As shown in animal studies, complement activation is associated with inflammation in the placenta and adverse pregnancy outcomes. The association between complement activation in humans and adverse pregnancy outcomes is unclear. The purpose of this study was to determine whether elevated levels of the activation fragment Bb in early pregnancy are predictive of preeclampsia. STUDY DESIGN This prospective study of 701 women was conducted in Denver, CO. A single plasma sample was obtained from each woman before 20 weeks’ gestation. The cohort was followed up throughout pregnancy for the development of preeclampsia. Analysis included multivariate logistic regression to adjust for established risk factors for preeclampsia. RESULTS Preeclampsia developed in 4.6% of the cohort. Women with elevated Bb (90th or greater percentile) were substantially more likely to develop preeclampsia than women who had levels less than the 90th percentile (unadjusted relative risk [RR], 3.3, 95% confidence interval [CI] 1.6 to 7, P = .0009). Other significant risk factors for preeclampsia included nulliparity (RR, 2.1, 95% CI, 1–4), a high body mass index (P = .006 for trend), and maternal medical (preexisting maternal hypertension, type 1 diabetes, systemic lupus erythematosus) disease (RR, 4.4, 95% CI, 2–10). Significant risk factors among multiparous women included a history of hypertension in a previous pregnancy (RR, 5, 95% CI, 1.6 to 16) and a change of paternity (RR, 5.1, 95% CI, 1.6 to 15). Adjustment for risk factors did not attenuate the association between an elevated Bb and preeclampsia (adjusted odds ratio [OR], 3.8, 95% CI, 1.6 to 9, P = .002) in the cohort. After removing women with plasma obtained before 10 weeks, the adjusted OR of Bb in the top decile for preeclampsia was 6.1 (95% CI 2.2, 17, P = .0005). CONCLUSION The complement activation product Bb in

Bangladesh has a high prevalence of adolescent pregnancy, but little is known about the nutritional status and dietary practices of Bangladeshi adolescents in early pregnancy or associated factors. We used the baseline data of 1552 pregnant adolescents from a longitudinal, cluster-randomized effectiveness trial conducted in northwest Bangladesh. Forty-four percent of the adolescents were short for their age, 36% had low body mass index, 28% were anemic, 10% had iron deficiency, and 32% had vitamin A deficiency. The mean consumption of animal-source foods was 10.3 times/week. In multivariate analysis, socioeconomic status, education, and food security were generally positively associated with anthropometric indicators and dietary practices but not with iron or vitamin A status. Our findings confirm that there is a high burden of undernutrition among these Bangladeshi adolescents in early pregnancy. Understanding factors related to undernutrition can help to identify adolescent pregnant women at higher risk and provide appropriate counseling and care. © 2018 New York Academy of Sciences.

In pregnancy, violence can have serious health consequences that could affect both mother and child. In Ghana there are limited data on this subject. We sought to assess the relationship between physical violence during pregnancy and pregnancy outcomes (early pregnancy loss, perinatal mortality and neonatal mortality) in Ghana. The 2008 Ghana Demographic and Health Survey data were used. For the domestic violence module, 2563 women were approached of whom 2442 women completed the module. After excluding missing values and applying the weight factor, 1745 women remained. Logistic regression analysis was performed to assess the relationship between physical violence in pregnancy and adverse pregnancy outcomes with adjustments for potential confounders. About five percent of the women experienced violence during their pregnancy. Physical violence in pregnancy was positively associated with perinatal mortality and neonatal mortality, but not with early pregnancy loss. The differences remained largely unchanged after adjustment for age, parity, education level, wealth status, marital status and place of residence: adjusted odds ratios were 2.32; 95% CI: 1.34-4.01 for perinatal mortality, 1.86; 95% CI: 1.05-3.30 for neonatal mortality and 1.16; 95% CI: 0.60-2.24 for early pregnancy loss. Our findings suggest that violence during pregnancy is related to adverse pregnancy outcomes in Ghana. Major efforts are needed to tackle violence during pregnancy. This can be achieved through measures that are directed towards the right target groups. Measures should include education, empowerment and improving socio-economic status of women.

Antithyroid drugs (ATDs) may have teratogenic effects, but more evidence is needed on the risk and types of birth defects after the use of methimazole (MMI) and propylthiouracil (PTU). This study aimed to evaluate the association between the use of ATDs in early pregnancy and birth defects. Swedish nationwide register-based cohort study. The study included 684 340 children live-born in Sweden from 2006 to 2012. Exposure groups defined by maternal ATD use in early pregnancy were MMI ( n  = 162); PTU ( n  = 218); MMI and PTU ( n  = 66); ATD before or after, but not in pregnancy ( n  = 1551) and non-exposed (never ATD ( n  = 682 343)). Outcome was cumulative incidence of birth defects diagnosed before two years of age. The cumulative incidence of birth defects was not significantly different in children exposed to MMI (6.8%, P  = 0.6) or PTU (6.4%, P  = 0.4) vs non-exposed (8.0%). For subtypes of birth defects, MMI was associated with an increased incidence of septal heart defects ( P  = 0.02). PTU was associated with ear ( P  = 0.005) and obstructive urinary system malformations ( P  = 0.006). A case of choanal atresia was observed after exposure to both MMI and PTU. The incidence of birth defects in children born to mothers who received ATD before or after, but not in pregnancy, was 8.8% and not significantly different from non-exposed ( P  = 0.3), MMI exposed ( P  = 0.4) or PTU exposed ( P  = 0.2). MMI and PTU were associated with subtypes of birth defects previously reported, but the frequency of ATD exposure in early pregnancy was low and severe malformations described in the MMI embryopathy were rarely observed. © 2017 European Society of Endocrinology.

Objective To determine if hyperglycosylated hCG (hhCG), produced by invasive trophoblasts, measured as early as 9 days after egg retrieval can predict ongoing pregnancies (OP) after in vitro fertilization and fresh embryo transfer (IVF-ET). Design Cohort Setting Academic ART center Patients Consecutive patients undergoing IVF-ET Interventions Serum hhCG and hCG levels measured 9 (D9) and 16 (D16) days after egg retrieval Outcome Ongoing pregnancy (OP) beyond 9 weeks of gestation Results OP (62 of 112 participants) was associated with higher D9 levels of hhCG and hCG However, hhCG was detectable in all D9 OP samples, while hCG was detectable in only 22%. D9 hhCG levels >110 pg/mL was 96% specific for OP, yielding a positive predictive value of 95%. Compared to D9 hCG levels, hhCG was more sensitive and had a larger area under the curve (0.87 vs. 0.67). Diagnostic test characteristics were similar between D16 hhCG and hCG levels. Conclusions In patients undergoing assisted reproduction, a test to detect pregnancy early and predict outcomes is highly desirable. HhCG is detectable in serum 9 days after egg retrieval IVF-ET cycles. At this early assessment, hhCG is superior to traditional hCG and highly predictive of ongoing pregnancies. PMID:24355054

In the present study, four RIA systems (RIA-1 to -4) based on two antisera raised against ovine pregnancy-associated glycoproteins (ovPAGs), combined with an ovine or a bovine PAG tracer were used to measure PAG concentrations in plasma and milk samples of dairy ewes. Blood and milk samples were collected on different days of gestation: 0, 18, 20, 22, 25, 28, 32, 42, and 49. From day 20 onward, the PAG in plasma could be detected in all pregnant ewes using the four RIA systems. By using milk, except for RIA-1, the other systems showed a sensitivity of 100% from day 28 of gestation onward. In plasma, PAG concentrations were higher in multiple than in single pregnancies, while no clear relationship was observed in milk. In conclusion, milk is a good alternative to plasma for early pregnancy diagnosis in sheep from day 28 to day 42. Copyright © 2014 Elsevier Ltd. All rights reserved.

Depression during pregnancy is associated with higher maternal morbidity and mortality, and subsequent possible adverse effects on the cognitive, emotional and behavioral development of the child. The aim of the study was to identify maternal characteristics associated with poor mental health, in a group of overweight/obese pregnant women in nine European countries, and thus, to contribute to better recognition and intervention for maternal depression. In this cross-sectional observational study, baseline data from early pregnancy (< 20 weeks) of the DALI (Vitamin D and Lifestyle Intervention for gestational diabetes mellitus prevention) study were analyzed. Maternal mental health was assessed with the World Health Organization Well-Being Index (WHO-5). Women were classified as having a low (WHO-5 ≤ 50) or high wellbeing. A total of 735 pregnant women were included. The prevalence of having a low wellbeing was 27.2%, 95% CI [24.0, 30.4]. Multivariate analysis showed independent associations between low wellbeing and European ethnicity, OR = .44, 95% CI [.25, .77], shift work, OR = 1.81, 95% CI [1.11, 2.93], insufficient sleep, OR = 3.30, 95% CI [1.96, 5.55], self-efficacy, OR = .95, 95% CI [.92, .98], social support, OR = .94, 95% CI [.90, .99], and pregnancy-related worries (socioeconomic: OR = 1.08, 95% CI [1.02, 1.15]; health: OR = 1.06, 95% CI [1.01, 1.11]; relationship: OR = 1.17, 95% CI [1.05, 1.31]). Mental health problems are common in European overweight/obese pregnant women. The identified correlates might help in early recognition and subsequent treatment of poor mental health problems during pregnancy. This is important to reduce the unfavorable effects of poor mental health on pregnancy outcomes. ISRCTN70595832 , 02.12.2011.

Pregnancy at early age is the most significant modifiable factor which consistently decreases lifetime breast cancer risk. However, the underlying mechanisms haven't been conclusively identified. Studies in mice suggest a reduction in progesterone-receptor (PR) sensitive epithelial cells as well as a downregulation of the Wnt signaling pathway as being one of the main mechanisms for the protective effect of early pregnancy. The aim of our study was to validate these findings in humans. We collected benign breast tissue of 125 women who had been stratified according to age at first pregnancy and the occurrence of subsequent breast cancer, and performed immunohistochemistry for PR, Wnt4 and the Wnt-target Versican. The number of PR positive epithelial cells was significantly lower in the group of women with early pregnancy and no subsequent breast cancer compared to the group of nulliparous women with subsequent invasive breast cancer (p = 0.0135). In women with early pregnancy, expression of Versican and Wnt4 was significantly lower compared to nulliparous women (p = 0.0036 and p = 0.0241 respectively), and Versican expression was also significant lower compared to women with late pregnancy (p < 0.0001). Our results confirm prior observations in mice and suggest a role of downregulation of epithelial Wnt signaling in the protective effect of early pregnancy in humans. This results in a decreased proliferation of stem/progenitor cells; therefore, the Wnt signaling pathway may represent a potential target for breast cancer prevention in humans.

Objectives To examine the association between adverse childhood experiences (ACEs) and pregnancy outcomes; to explore mediators of this association including psychiatric illness and health habits. Methods Exposure to ACEs was determined by the Early Trauma Inventory Self Report Short Form; psychiatric diagnoses were generated by the Composite International Diagnostic Interview administered in a cohort of 2303 pregnant women. Linear regression and structural equation modeling bootstrapping approaches tested for multiple mediators. Results Each additional ACE decreased birth weight by 16.33 g and decreased gestational age by 0.063. Smoking was the strongest mediator of the effect on gestational age. Conclusions ACEs have an enduring effect on maternal reproductive health, as manifested by mothers’ delivery of offspring that were of reduced birth weight and shorter gestational age. PMID:26762511

Retrospective analysis of the early spontaneous abortions has been conducted (486 cases). Histomorphologic analysis of the curettage material contents erveledinvolutive-regressive developmental chsnges in 108 (22,28%) cases, in 370 cases (77.78%) pathologic changes, like inflammatory changes of deciduas and chorionic villis in 302 cases (80.2%), pathologic prematurity of chorionic vili in 48 cases (12.6%), hydatidiform mole in 28 cases (7.4%). As most cases of pregnancy loss has been reported at 7-9 weeks /172 cases/, we compared histomorphologic data revealed at 7-8 (71 cases) weeks to 5-6 (135 cases) and 10-12 weeks of gestation. Morphologic research data confimed, that at 7-8 weeks compared to 5-6 weeks leading reason ofpregnancy loss was inflammatory changes (OR-1,584), what can be cause of 110 pregnancy losses at 1000 pregnant women (AR-0.11). Data comparing7-9 weeks to 10-12 weeks pregnancy losses, confirm the priority of pathologic immaturity (OR-1,279) and hydatidiform mole (OR-1,557) and could be the risk of 100 cases of pregnancy termination at 1000 pregnant women (AR-0.10).Existing results are of great importance for the preconceptional preparation of women.

The use of antiandrogen drugs such as finasteride during pregnancy may carry the risk of birth defects, especially hypospadias. We report a 39-year-old woman, with 5 weeks unplanned pregnancy, the patient conceived while receiving daily dose of finasteride 2.5 mg for treatment of alopecia. The patient's partner was concurrently using finasteride for the same purpose. Ultrasound scans including detailed anatomy were normal throughout pregnancy and the fetal gender was detected to be male. The patient had her delivery at 38 +5 weeks' gestation, by elective cesarean section, a male infant with a weight of 3.58 kg and Apgar score of 9 and 10 at 1 and 5-min, respectively. The infant was healthy with no obvious dysmorphic features. In this case report, maternal use of finasteride in early pregnancy was not associated with external genitalia abnormalities of a male baby. Moreover, maternal exposure to the semen of partner who received finasteride did not adversely affect the short term neonatal outcomes. However, absence of apparent neonatal adverse effects in a single case report does not indicate safety of use. Population-based long term neonatal outcomes are yet to be established.

Objectives Beginning life in a healthy uterine environment is essential for future well-being, particularly as it relates to chronic disease risk. Baseline (early pregnancy) demographic, anthropometric (height and weight), psychosocial (depression and perceived stress), and behavioral (diet and exercise) characteristics of rural, Southern, pregnant women enrolled in a maternal, infant, and early childhood home visiting program are described. Methods Participants included 82 women early in their second trimester of pregnancy and residing in three Lower Mississippi Delta counties in the United States. Baseline data were collected through direct measurement and surveys. Results Participants were primarily African American (96 %), young (mean age = 23 years), single (93 %), and received Medicaid (92 %). Mean gestational age was 18 weeks, 67 % of participants were overweight or obese before becoming pregnant, and 16 % tested positive for major depression. Participants were sedentary (mean minutes of moderate intensity physical activity/week = 30), had low diet quality (mean Healthy Eating Index-2010 total score = 43 points), with only 38, 4, and 7 % meeting recommendations for saturated fat, fiber, and sodium intakes, respectively. Conclusions for Practice In the Lower Mississippi Delta, there is a need for interventions that are designed to help women achieve optimal GWG by improving their diet quality and increasing the amount of physical activity performed during pregnancy. Researchers also should consider addressing barriers to changing health behaviors during pregnancy that may be unique to this region of the United States.

Biomonitoring of human fetal exposure to environmental chemicals in early pregnancy.

Cooke, Gerard M

2014-01-01

The first trimester of human fetal life, a period of extremely rapid development of physiological systems, represents the most rapid growth phase in human life. Interference in the establishment of organ systems may result in abnormal development that may be manifest immediately or programmed for later abnormal function. Exposure to environmental chemicals may be affecting development at these early stages, and yet there is limited knowledge of the quantities and identities of the chemicals to which the fetus is exposed during early pregnancy. Clearly, opportunities for assessing fetal chemical exposure directly are extremely limited. Hence, this review describes indirect means of assessing fetal exposure in early pregnancy to chemicals that are considered disrupters of development. Consideration is given to such matrices as maternal hair, fingernails, urine, saliva, sweat, breast milk, amniotic fluid and blood, and fetal matrices such as cord blood, cord tissue, meconium, placenta, and fetal liver. More than 150 articles that presented data from chemical analysis of human maternal and fetal tissues and fluids were reviewed. Priority was given to articles where chemical analysis was conducted in more than one matrix. Where correlations between maternal and fetal matrices were determined, these articles were included and are highlighted, as these may provide the basis for future investigations of early fetal exposure. The determination of fetal chemical exposure, at the time of rapid human growth and development, will greatly assist regulatory agencies in risk assessments and establishment of advisories for risk management concerning environmental chemicals.

High-frequency ultrasonography (HFUS) is a common method to non-invasively monitor the real-time development of the human fetus in utero. The mouse is routinely used as an in vivo model to study embryo implantation and pregnancy progression. Unfortunately, such murine studies require pregnancy interruption to enable follow-up phenotypic analysis. To address this issue, we used three-dimensional (3-D) reconstruction of HFUS imaging data for early detection and characterization of murine embryo implantation sites and their individual developmental progression in utero. Combining HFUS imaging with 3-D reconstruction and modeling, we were able to accurately quantify embryo implantation site number as well as monitor developmental progression in pregnant C57BL6J/129S mice from 5.5 days post coitus (d.p.c.) through to 9.5 d.p.c. with the use of a transducer. Measurements included: number, location, and volume of implantation sites as well as inter-implantation site spacing; embryo viability was assessed by cardiac activity monitoring. In the immediate post-implantation period (5.5 to 8.5 d.p.c.), 3-D reconstruction of the gravid uterus in both mesh and solid overlay format enabled visual representation of the developing pregnancies within each uterine horn. As genetically engineered mice continue to be used to characterize female reproductive phenotypes derived from uterine dysfunction, this method offers a new approach to detect, quantify, and characterize early implantation events in vivo. This novel use of 3-D HFUS imaging demonstrates the ability to successfully detect, visualize, and characterize embryo-implantation sites during early murine pregnancy in a non-invasive manner. The technology offers a significant improvement over current methods, which rely on the interruption of pregnancies for gross tissue and histopathologic characterization. Here we use a video and text format to describe how to successfully perform ultrasounds of early murine pregnancy to

Lower early postnatal oxygen saturation target and risk of ductus arteriosus closure failure.

Early postnatal hyperoxia is a major risk factor for retinopathy of prematurity (ROP) in extremely premature infants. To reduce the occurrence of ROP, we adopted a lower early postnatal oxygen saturation (SpO 2 ) target range (85-92%) from April 2011. Lower SpO 2 target range, however, may lead to hypoxemia and an increase in the risk of ductus arteriosus (DA) closure failure. The aim of this study was therefore to determine whether a lower SpO 2 target range, during the early postnatal stage, increases the risk of DA closure failure. Infants born at <28 weeks' gestation were enrolled in this study. Oxygen saturation target range during the first postnatal 72 h was 84-100% in study period 1 and 85-92% in period 2. Eighty-two infants were included in period 1, and 61 were included in period 2. The lower oxygen saturation target range increased the occurrence of hypoxemia during the first postnatal 72 h. Prevalence of DA closure failure in period 2 (21%) was significantly higher than that in period 1 (1%). On multivariate logistic regression analysis, the lower oxygen saturation target range was an independent risk factor for DA closure failure. Lower early postnatal oxygen saturation target range increases the risk of DA closure failure. © 2016 Japan Pediatric Society.

Around the world, the incidence of multiple pregnancies reaches its peak in the Central African countries and often represents an increased risk of death for women and children because of higher rates of obstetrical complications and poor management skills in those countries. We sought to assess the association between twins and early neonatal mortality compared with singleton pregnancies. We also assessed the role of skilled birth attendant and mode of delivery on early neonatal mortality in twin pregnancies. We conducted a secondary analysis of individual level data from 60 nationally-representative Demographic and Health Surveys including 521 867 singleton and 14 312 twin births. We investigated the occurrence of deaths within the first week of life in twins compared to singletons and the effect of place and attendance at birth; also, the role of caesarean sections against vaginal births was examined, globally and after countries stratification per caesarean sections rates. A multi-level logistic regression was used accounting for homogeneity within country, and homogeneity within twin pairs. Early neonatal mortality among twins was significantly higher when compared to singleton neonates (adjusted odds ratio (aOR) 7.6; 95% confidence interval (CI) = 7.0-8.3) in these 60 countries. Early neonatal mortality was also higher among twins than singletons when adjusting for birth weight in a subgroup analysis of those countries with data on birth weight (n = 20; less than 20% of missing values) (aOR = 2.8; 95% CI = 2.2-3.5). For countries with high rates (>15%) of caesarean sections (CS), twins delivered vaginally in health facility had a statistically significant (aOR = 4.8; 95% CI = 2.4-9.4) increased risk of early neonatal mortality compared to twins delivered through caesarean sections. Home twin births without SBA was associated with increased mortality compared with delivering at home with SBA (aOR = 1.3; 95% CI = 1.0-1.8) and

To evaluate the efficiency of different ultrasound devices in achieving an early diagnosis of pregnancy in dairy herds. A total of 1976 Holstein Friesian cows and heifers were artificially inseminated (AI) according to the herd manager's regime. Pregnancy diagnostics were performed between day 26 and 35 after AI using six different types of ultrasound systems (linear vs. sector scanners). Manual rectal palpation between day 45 and 60 after AI was used as the gold standard for pregnancy diagnostics. Sensitivity (SENS), specificity (SPEC), positive (PPV) and negative predictive value (NPV) and diagnostic accuracy (ACC) of the diagnostic measures were determined. Average SENS was 82% (range 67.7-95.2%) with a mean SPEC of 73% (range 50.0-81.0%). ACC was 78.2% with a minimum of 64.6% and a maximum of 89.4%, depending on the ultrasound system. The PPV (ratio of the number of pregnant cows with a positive examination result to the number of cows actually pregnant) was 80.8% (range 59.1-88.1%), whereas the NPV (defined as the ratio of the number of cows correctly diagnosed negative to the number of cows actually open) was 74.4% (72.3-91.9%). Significant differences for these parameters were found depending on the ultrasound system used (p ≤ 0.01; Cramer's V. = 0.14). Regardless of the ultrasound device used, early pregnancy diagnostics between day 26 and 35 show a moderate diagnostic efficiency. Comparing the accuracy of the different devices, there may be a significant influence of type and technical parameters. Even though ultrasound systems with mechanical sector probes are not as convenient to use as systems with linear probes, according to this study, sector scanners are a reasonable alternative.

The recent limitation in the provision of publicly-funded family planning services in Iran has concerned stakeholders in reproductive health about the incidence of unintended pregnancies. This study used data from Hamedan Survey of Fertility, conducted in April-June 2015 among a representative sample of 3,000 married women aged 15-49 years living in the city of Hamedan (Iran), to estimate levels of unintended pregnancies and examine factors related to pregnancy intentions for the most recent birth, using multinomial logistic regression analyses. Results showed that 23% of pregnant women reported their pregnancy as unintended (17% mistimed and 6% unwanted). Moreover, unintended pregnancies in the five years preceding the survey were the result of failures of withdrawal (35%) and of modern contraceptive use (33%), along with contraceptive discontinuation (23%) and nonuse (9%). Multivariate results indicated that the risk of unintended pregnancy was lower among women reporting modern contraceptive failures and lower among those reporting contraceptive discontinuation and nonuse, compared with women experiencing withdrawal failures. The high incidence of unintended pregnancies among women experiencing contraceptive failures and discontinuation imply their high unmet need for contraceptive knowledge and counseling rather than for access to contraceptive methods.

Embryo evaluation and selection is fundamental in clinical IVF. Time-lapse follow-up of embryo development comprises undisturbed culture and the application of the visual information to support embryo evaluation. A meta-analysis of randomized controlled trials was carried out to study whether time-lapse monitoring with the prospective use of a morphokinetic algorithm for selection of embryos improves overall clinical outcome (pregnancy, early pregnancy loss, stillbirth and live birth rate) compared with embryo selection based on single time-point morphology in IVF cycles. The meta-analysis of five randomized controlled trials (n = 1637) showed that the application of time-lapse monitoring was associated with a significantly higher ongoing clinical pregnancy rate (51.0% versus 39.9%), with a pooled odds ratio of 1.542 (P < 0.001), significantly lower early pregnancy loss (15.3% versus 21.3%; OR: 0.662; P = 0.019) and a significantly increased live birth rate (44.2% versus 31.3%; OR 1.668; P = 0.009). Difference in stillbirth was not significant between groups (4.7% versus 2.4%). Quality of the evidence was moderate to low owing to inconsistencies across the studies. Selective application and variability were also limitations. Although time-lapse is shown to significantly improve overall clinical outcome, further high-quality evidence is needed before universal conclusions can be drawn. Copyright © 2017 The Author(s).

This is the first study to ascertain the value of multidisciplinary team (MDT) meetings within an early pregnancy assessment unit (EPAU). Our national telephone survey identified that in the United Kingdom, overall 37% of EPAU utilise regular MDT meetings. Secondary and tertiary hospitals are just as likely to hold regular MDT meetings. The participants in our interview study expressed the principal benefits of regular MDT meetings as communication, education and effective stress management. The perceived additional benefits included improved care quality, better patient experience and enhanced team cohesion. During the meetings, at least, one representative from every tier of staffing was present. The caseload of the MDT meeting comprised ectopic pregnancies and pregnancies of unknown location. We propose a number of research studies, which would build on this study. Such efforts will help enhance the effectiveness of the MDT-based EPAU service.

Hypertensive disorders of pregnancy are a leading cause of maternal and perinatal morbidity and mortality. Early suppression of B-cell lymphopoiesis is necessary for a normal pregnancy. Dysregulation of factors critical to B-cell survival may result in pregnancy complications, including hypertension. In this prospective observational study at a single medical center, serum levels of BAFF (B-cell activating factor) were measured in pregnant participants at each trimester, at delivery, and postpartum and in nonpregnant controls at a single time point. Comparisons were made between nonpregnant and pregnant subjects and between time periods of pregnancy. First-trimester serum BAFF levels were further tested for association with hypertensive disorders of pregnancy. The study included 149 healthy pregnant women, 25 pregnant women with chronic hypertension, and 48 nonpregnant controls. Median first-trimester serum BAFF level (ng/mL) for healthy women (0.90) was lower than median serum BAFF levels for women with chronic hypertension (0.96; P =0.013) and controls (1.00; P =0.002). Serum BAFF levels steadily declined throughout pregnancy, with the median second-trimester level lower than the corresponding first-trimester level (0.77; P =0.003) and the median third-trimester level lower than the corresponding second-trimester level (0.72; P =0.025). The median first-trimester serum BAFF level was elevated in women who subsequently developed hypertension compared with women who remained normotensive (1.02 versus 0.85; P =0.012), with the area under the receiver operating characteristic curve being 0.709. First-trimester serum BAFF level may be an early and clinically useful predictor of hypertensive disorders of pregnancy. © 2017 American Heart Association, Inc.

We apply an innovative and novel analytic approach, based on reliability engineering (RE) principles frequently used to characterize the behavior of manufactured products, to examine outcomes after peripheral endovascular intervention. We hypothesized that this would allow for improved prediction of outcome after peripheral endovascular intervention, specifically with regard to identification of risk factors for early failure. Patients undergoing infrainguinal endovascular intervention for chronic lower-extremity ischemia from 2005 to 2010 were identified in a prospectively maintained database. The primary outcome of failure was defined as patency loss detected by duplex ultrasonography, with or without clinical failure. Analysis included univariate and multivariate Cox regression models, as well as RE-based analysis including product life-cycle models and Weibull failure plots. Early failures were distinguished using the RE principle of "basic rating life," and multivariate models identified independent risk factors for early failure. From 2005 to 2010, 434 primary endovascular peripheral interventions were performed for claudication (51.8%), rest pain (16.8%), or tissue loss (31.3%). Fifty-five percent of patients were aged ≥75 years; 57% were men. Failure was noted after 159 (36.6%) interventions during a mean follow-up of 18 months (range, 0-71 months). Using multivariate (Cox) regression analysis, rest pain and tissue loss were independent predictors of patency loss, with hazard ratios of 2.5 (95% confidence interval, 1.6-4.1; P < 0.001) and 3.2 (95% confidence interval, 2.0-5.2, P < 0.001), respectively. The distribution of failure times for both claudication and critical limb ischemia fit distinct Weibull plots, with different characteristics: interventions for claudication demonstrated an increasing failure rate (β = 1.22, θ = 13.46, mean time to failure = 12.603 months, index of fit = 0.99037, R(2) = 0.98084), whereas interventions for critical limb

The objective of this study was to evaluate the ability of near-infrared reflectance spectroscopy (NIRS) to discriminate between pregnant and nonpregnant ewes in early stages of pregnancy after artificial insemination (AI) from blood plasma. Samples were collected using jugular puncture at 18 and 25 days after AI from 188 Rasa Aragonesa and Ansotana ewes. Plasma samples were analyzed for pregnancy-associated glycoprotein (PAG) and progesterone (P4) using ELISA commercial kits. The spectra of plasma samples were recorded in the visible and near-infrared ranges. The performance of these tests were compared, using as criterion standard the pregnancy status determined using transabdominal ultrasonography at 45 days after AI. Pregnancy rate was 47.9% (90/188). At Day 18, sensitivity was similar in NIRS and P4 tests (98.9% vs. 100%; not significant) and greater than PAG (32.2%; both P < 0.001). Specificity was similar in NIRS and PAG tests (both 100%) and greater than that of P4 (84.7%; P < 0.001). At Day 25, sensitivity and specificity of NIRS and PAG were both 100%. It can be concluded that NIRS was an accurate method of diagnosis of pregnancy at Days 18 and 25 after AI in ewes. Copyright © 2014 Elsevier Inc. All rights reserved.

Interferon-τ increases BoLA-I for implantation during early pregnancy in dairy cows.

Interferon-τ (IFN-τ) signals pregnancy recognition in ruminants. We investigated the effects of IFN-τ produced by embryo trophoblastic cells (ETCs) on expression of bovine leukocyte antigen-I (BoLA-I), a bovine analogue of human MHC-I, in endometrial luminal epithelial cells (EECs) during early pregnancy in dairy cows. Expression of IFN-τ and BoLA-I was increased in endometrial tissues during early pregnancy. Expression of the anti-inflammatory cytokine IL-10 was increased in endometrial tissues, while expression of the pro-inflammatory cytokine IL-6 was decreased, indicating immunosuppression. Progesterone increased IFN-τ expression in EECs. IFN-τ increased p-STAT1 and p-STAT3 levels in EECs, but reduced TRAF3 levels. In addition, IFN-τ increased expression of BoLA-I and IL-10, but decreased expression of IL-6 in EECs. These results indicate that IFN-τ enables stable implantation in dairy cows by increasing expression of BoLA-I, and by immunosuppression mediated by increased IL-10 and decreased IL-6 expression.

Subclinical hypothyroidism is common in pregnant women and often related to adverse pregnancy outcomes, but its relationship with gestational diabetes remains controversial. In particular, the impact of thyroperoxidase antibodies status on the relationship between subclinical hypothyroidism and gestational diabetes is not clear. We investigated the association between combined thyroid stimulating hormone (TSH) level and thyroperoxidase antibodies status in early pregnancy (<20 weeks of gestation) and gestational diabetes mellitus. A total of 7084 pregnant women met the inclusion criteria, which included thyroperoxidase antibodies-positive subclinical hypothyroidism [TSH(H)TPOAb(+)] (n = 78), thyroperoxidase antibodies-negative subclinical hypothyroidism [TSH(H)TPOAb(-)] (n = 281), thyroperoxidase antibodies-positive euthyroidism [TSH(N)TPOAb(+)] (n = 648), and thyroperoxidase antibodies-negative euthyroidism [TSH(N)TPOAb(-)] (n = 6077). Of the 7084 cases included in our study, 1141 cases were diagnosed with gestational diabetes mellitus at 24-28 weeks of pregnancy. The prevalence of gestational diabetes mellitus in TSH(N)TPOAb(-), TSH(H)TPOAb(-), TSH(N)TPOAb(+), and TSH(H)TPOAb(+) was 14.65, 19.57, 24.85, and 46.15 %, respectively. Compared with TSH(N)TPOAb(-) women, the risk of gestational diabetes mellitus was increased in all other groups of women in early pregnancy. After dividing early pregnancy into first and second trimesters, we found that TSH(H)TPOAb(-) women in the first trimester do not show this increase. Our study suggests that subclinical hypothyroidism and thyroperoxidase antibodies-positive euthyroidism in early pregnancy are associated with an increased risk of gestational diabetes mellitus.

Ebstein's anomaly is a rare congenital cardiac abnormality, associated with cyanosis and arrhythmia. Patients often reach childbearing age and pregnant women pose a challenge to the treating physician. We describe the course and outcome of pregnancy in women with Ebstein's anomaly and discuss the related management issues. Analysis of pregnancies in four women with Ebstein's anomaly was carried out in a referral institute in northern India. Data of two women were analyzed retrospectively and the other two women were prospectively followed in their pregnancies during the study period. The course of the pregnancy, disease and perinatal outcome in each woman were analyzed. Four women had eight pregnancies all resulting in vaginal deliveries. There were two premature deliveries. The mean birth weight was 2.54 + or - 0.88 kg. Of the eight babies, six did not have any cardiac anomalies; one was an unexplained neonatal death and for another, no data was available. Pregnancy was well tolerated in two patients, while one had right heart failure during early pregnancy, and one had arrhythmia during labor, which was managed medically; one patient had arrhythmia in the postpartum period, which was managed medically. When a woman with Ebstein's anomaly reaches childbearing age, fertility is not affected, even in cyanotic women. Under close supervision by the woman's obstetrician and cardiologist, the pregnancy outcome is usually favorable.

Inability to have children caused by recurrent HELLP syndrome in early pregnancies - implications for a review of literature.

This review is inspired by a case of two pregnancies of the same patient complicated by HELLP syndrome, which suggests that there is a predisposition for the occurrence of preeclampsia and HELLP syndrome in early pregnancy. HELLP syndrome, uncommon below the 20th week and rarer still in two consecutive pregnancies, appeared in two pregnancies of the same woman. The aim of our work is to try to understand the cause of heterogeneity of HELLP syndrome and help find a way of prolonging such pregnancies. Recurrent HELLP syndrome in early pregnancy is a form of severe, fulminant preeclampsia. The preceding symptom is a surge in blood pressure. The hypertension becomes resistant to antihypertensive drugs, which indicates that preexisting hypertension is later accompanied by other factors contributing to the rise in blood pressure. Different effects of high dosage of corticosteroids on liver and platelets show that there are different factors responsible for liver damage and for thrombocytopenia. It seems that the symptoms have various origins, so the therapy with one drug only is not sufficiently effective. Nicotine analogues or a plant extract (from rootstock of Eriosema kraussianum) used by South African traditional healers for erectile dysfunction seem to give a chance of prolonging pregnancy and, consequently, having children.

The survival rate of infants and children with intestinal failure is increasing, necessitating a greater focus on their developmental trajectory. To evaluate neurodevelopmental outcomes in children with intestinal failure at 0-15months corrected age. Analysis of clinical, demographic and developmental assessment results of 33 children followed in an intestinal rehabilitation program between 2011 and 2014. Outcome measures included: Prechtl's Assessment of General Movements, Movement Assessment of Infants, Alberta Infant Motor Scale and Mullen Scales of Early Learning. Clinical factors were correlated with poorer developmental outcomes at 12-15months corrected age. Thirty-three infants (17 males), median gestational age 34weeks (interquartile range 29.5-36.0) with birth weight 1.98kg (interquartile range 1.17-2.50). Twenty-nine (88%) infants had abnormal General Movements. More than half had suspect or abnormal scores on the Alberta Infant Motor Scale and medium to high-risk scores for future neuromotor delay on the Movement Assessment of Infants. Delays were seen across all Mullen subscales, most notably in gross motor skills. Factors significantly associated with poorer outcomes at 12-15months included: prematurity, low birth weight, central nervous system co-morbidity, longer neonatal intensive care admission, necrotizing enterocolitis diagnosis, number of operations and conjugated hyperbilirubinemia. Multiple risk factors contribute to early developmental delay in children with intestinal failure, highlighting the importance of close developmental follow-up. Copyright © 2016 Elsevier Ireland Ltd.

Uterine volumes measured by two different ultrasonic methods, and gestation sac volumes in early normal pregnancy are reported. The results obtained for uterine volume measurements are compared. Methods using measurements obtained from only a longitudinal scan were simpler but slightly less accurate. Uterine volumes were also calculated in a series of patients with pregnancy complicated by threatened abortion. The accuracy of the prediction of the outcome of the pregnancy, based solely on uterine volume was 71 percent. Uterine volume measurement is most useful in identifying cases of missed abortion where the period of gestation is known.

The objective of the study was to characterize the developmental sequence of pre- and postnatal risk factors for inattention-hyperactivity symptoms in preschoolers. Longitudinal data came from a French population based birth cohort study (EDEN; N = 1311 mother-child pairs followed from the pregnancy onwards). Inattention-hyperactivity symptoms were assessed with the Strengths and Difficulties Questionnaire when participating children were 3 years of age. Potential risk factors were classified in four domains (fetal exposures and child somatic characteristics, child temperament, child neurodevelopmental status, psychosocial environment) and four periods (before pregnancy, prenatal/birth, infancy, toddlerhood). Their role as potential moderator or mediator was tested with path analysis to determine the developmental sequence. A low family socioeconomic status before pregnancy was the main environmental risk factor for inattention-hyperactivity symptoms at 3 years, and its effect occurred via two pathways. The first was a risk pathway, where lower SES was associated with higher maternal depression and anxiety during pregnancy; then to higher maternal and child distress and dysregulation in infancy; and in turn to higher levels of inattention-hyperactivity at 3 years. The second was a protective pathway, where higher SES was associated with longer duration of breastfeeding during infancy; then to better child neurodevelopmental status in toddlerhood; and in turn to lower levels of inattention-hyperactivity at 3 years. This study identified psychosocial factors at several developmental periods that represent potential targets for preventing the emergence of inattention-hyperactivity symptoms in early childhood.

Inflammatory immune response plays a key role in reproductive failures such as multiple implantation failures (MIF), early pregnancy loss, and recurrent pregnancy losses (RPL). Cellular immune responses particularly mediated by natural killer (NK), and T cells are often dysregulated in these conditions. Excessive or inappropriate recruitment of peripheral blood NK cells to the uterus may lead to cytotoxic environment in utero, in which proliferation and differentiation of trophoblast is hampered. In addition, inadequate angiogenesis by uterine NK cells often leads to abnormal vascular development and blood flow patterns, which, in turn, leads to increased oxidative stress or ischemic changes in the invading trophoblast. T-cell abnormalities with increased Th1 and Th17 immunity, and decreased Th2 and T regulatory immune responses may play important roles in RPL and MIF. A possible role of stress in inflammatory immune response is also reviewed. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Graves' disease, a well-known cause of hyperthyroidism, is an autoimmune disease with multi-system involvement. More prevalent among young women, it appears as an uncommon cardiovascular complication during pregnancy, posing a diagnostic challenge, largely owing to difficulty in detecting the complication, as a result of a low index of suspicion of Graves' disease presenting during pregnancy. Globally, cardiovascular disease is an important factor for pregnancy-related morbidity and mortality. Here, we report a case of Graves' disease detected for the first time in pregnancy, in a patient presenting with bi- ventricular heart failure, severe pulmonary hypertension and pre- eclampsia. Emphasis is placed on the spectrum of clinical presentations of Graves' disease, and the importance of considering this thyroid disorder as a possible aetiological factor for such a presentation in pregnancy. A 30-year-old Bangladeshi-Bengali woman, in her 28th week of pregnancy presented with severe systemic hypertension, bi-ventricular heart failure and severe pulmonary hypertension with a moderately enlarged thyroid gland. She improved following the administration of high dose intravenous diuretics, and delivered a premature female baby of low birth weight per vaginally, twenty four hours later. Pre-eclampsia was diagnosed on the basis of hypertension first detected in the third trimester, 3+ oedema and mild proteinuria. Electrocardiography revealed sinus tachycardia with incomplete right bundle branch block and echocardiography showed severe pulmonary hypertension with an estimated pulmonary arterial systolic pressure of 73 mm Hg, septal and anterior wall hypokinesia with an ejection fraction of 51%, grade I mitral and tricuspid regurgitation. Thyroid function tests revealed a biochemically hyperthyroid state and positive anti- thyroid peroxidase antibodies was found.

Background Around the world, the incidence of multiple pregnancies reaches its peak in the Central African countries and often represents an increased risk of death for women and children because of higher rates of obstetrical complications and poor management skills in those countries. We sought to assess the association between twins and early neonatal mortality compared with singleton pregnancies. We also assessed the role of skilled birth attendant and mode of delivery on early neonatal mortality in twin pregnancies. Methods We conducted a secondary analysis of individual level data from 60 nationally-representative Demographic and Health Surveys including 521 867 singleton and 14 312 twin births. We investigated the occurrence of deaths within the first week of life in twins compared to singletons and the effect of place and attendance at birth; also, the role of caesarean sections against vaginal births was examined, globally and after countries stratification per caesarean sections rates. A multi-level logistic regression was used accounting for homogeneity within country, and homogeneity within twin pairs. Results Early neonatal mortality among twins was significantly higher when compared to singleton neonates (adjusted odds ratio (aOR) 7.6; 95% confidence interval (CI) = 7.0-8.3) in these 60 countries. Early neonatal mortality was also higher among twins than singletons when adjusting for birth weight in a subgroup analysis of those countries with data on birth weight (n = 20; less than 20% of missing values) (aOR = 2.8; 95% CI = 2.2-3.5). For countries with high rates (>15%) of caesarean sections (CS), twins delivered vaginally in health facility had a statistically significant (aOR = 4.8; 95% CI = 2.4-9.4) increased risk of early neonatal mortality compared to twins delivered through caesarean sections. Home twin births without SBA was associated with increased mortality compared with delivering at home with SBA (aOR = 1

OBJECTIVE We sought to examine the association between maternal serum 25-hydroxyvitamin D (25[OH]D) concentration in early pregnancy and the subsequent diagnosis of preeclampsia (PE). STUDY DESIGN This was a nested case-control study from 2 prospective Canadian cohorts conducted in Quebec City, Quebec, and Halifax, Nova Scotia, from 2002 through 2010. Participants were pregnant women (n=169 cases with PE and 1975 controls). Maternal serum was drawn <20 weeks of gestation, and 25(OH)D measurement was performed. Cases were ascertained from medical records. Logistic regression analysis was used to estimate adjusted odds ratios with 95% confidence intervals. RESULTS Women who developed PE had a significantly lower 25(OH)D concentration at a mean gestational age of 14 weeks compared with women in the control group (mean ± SD 25[OH]D 47.2 ± 17.7 vs 52.3 ± 17.2 nmol/L, P < .0001). Women with 25(OH)D <30 nmol/L compared to those with at least 50 nmol/L had a greater risk of developing PE (adjusted odds ratio, 2.23; 95% confidence interval, 1.29–3.83) after adjustment for prepregnancy body mass index, maternal age, smoking, parity, season and year of blood collection, gestational week at blood collection, and cohort site. Exploratory analysis with cubic splines demonstrated a dose-response relationship between maternal 25(OH)D and risk of PE, up to levels around 50 nmol/L, where the association appeared to plateau. CONCLUSION Maternal vitamin D deficiency early in pregnancy defined as 25(OH)D<30 nmol/L may be an independent risk factor for PE. The relevance of vitamin D supplementation for women of child-bearing age should be explored as a strategy for reducing PE and for promoting a healthier pregnancy. PMID:25446694

Sonographic findings of early pregnancy in the rudimentary horn of a unicornuate uterus: A two case report.

PubMed

Dove, Christine K; Harvey, Sara M; Spalluto, Lucy B

Congenital uterine anomalies have a profound impact on reproductive outcomes. The unicornuate uterus accounts for approximately 20% of all congenital uterine anomalies. Unicornuate uterine anomalies with non-communicating rudimentary horns are at risk of developing ectopic pregnancy in the rudimentary horn. Given increased risked of uterine rupture, rudimentary horn pregnancies pose significant maternal health risks. Understanding the sonographic appearance of early pregnancy within the rudimentary horn of the unicornuate uterine configuration is imperative for appropriate and timely clinical management. We present two cases of pregnancy in the rudimentary horn of a unicornuate uterus diagnosed sonographically in the first trimester. Published by Elsevier Inc.

Dendritic cell (DC) and natural killer (NK) cell interactions are important for the regulation of innate and adaptive immunity, but their relevance during early pregnancy remains elusive. Using two different strategies to manipulate the frequency of NK cells and DC during gestation, we investigated their relative impact on the decidualization process and on angiogenic responses that characterize murine implantation. Manipulation of the frequency of NK cells, DC or both lead to a defective decidual response characterized by decreased proliferation and differentiation of stromal cells. Whereas no detrimental effects were evident upon expansion of DC, NK cell ablation in such expanded DC mice severely compromised decidual development and led to early pregnancy loss. Pregnancy failure in these mice was associated with an unbalanced production of anti-angiogenic signals and most notably, with increased expression of genes related to inflammation and immunogenic activation of DC. Thus, NK cells appear to play an important role counteracting potential anomalies raised by DC expansion and overactivity in the decidua, becoming critical for normal pregnancy progression.

Background. Maternal thyroid dysfunction in early pregnancy may increase the risk of adverse pregnancy complications and neurocognitive deficiencies in the developing fetus. Currently, some researchers demonstrated that body mass index (BMI) is associated with thyroid function in nonpregnant population. Hence, the American Thyroid Association recommended screening thyroid function in obese pregnant women; however, the evidence for this is weak. For this purpose, our study investigated the relationship between high BMI and thyroid functions during early pregnancy in Liaoning province, an iodine-sufficient region of China. Methods. Serum thyroid stimulating hormone (TSH), free thyroxine (FT4), thyroid-peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb) concentration, urinary iodine concentration (UIC), and BMI were determined in 6303 pregnant women. Results. BMI ≥ 25 kg/m2 may act as an indicator of hypothyroxinemia and TPOAb positivity and BMI ≥ 30 kg/m2 was associated with increases in the odds of hypothyroidism, hypothyroxinemia, and TPOAb positivity. The prevalence of isolated hypothyroxinemia increased among pregnant women with BMI > 24 kg/m2. Conclusions. High BMI during early pregnancy may be an indicator of maternal thyroid dysfunction; for Asian women whose BMI > 24 kg/m2 and who are within 8 weeks of pregnancy, thyroid functions should be assessed especially.

In surrogate pregnancies the genetic parents have little opportunity for early bonding to their infant, either prenatally (in utero) or in the immediate postnatal period. The purpose of this article is to describe a new method for encouraging early parent-infant bonding after surrogate pregnancy by hospitalizing the genetic mother in the maternity ward immediately after the delivery. Two genetic mothers were hospitalized in the maternity ward (rooming-in system) at the Rabin Medical Center in Israel immediately after delivery of their infants by surrogate arrangement. The first birth was a singleton pregnancy with vaginal delivery and the second, a twin pregnancy with delivery by cesarean section. The genetic parents were counseled by a social worker from the adoption agency, starting 3 months before the estimated date of delivery. The parents were referred to the hospital social worker before the delivery. To assess attachment, we observed the parents' behavior toward their children during two daily 15-minute periods of free, unstructured interaction. The parents showed good primary caregiving functions and established affective verbal and physical contact with the infants. They began to recognize the infants' needs and temperament, and exhibited an aura of self-confidence during their interactions. All expressed satisfaction with the method at discharge and reported on reduction of their fears about returning home with the infants. We believe that early hospitalization of the genetic mother in a surrogate delivery may be desirable to establish good and safe early mother-infant bonding, and that it should be considered for adoption as regular hospital policy. Further randomized studies with larger samples over the long term are warranted.

To evaluate the advantages and disadvantages of early-early pregnancy induced abortion (EPIA). A total of 10 404 cases of EPIA performed at our hospital from January 1993 to December 2003 were retrospectively analyzed and compared with 9434 cases of common induced abortion (CIA). The amount of hemorrhage and operative duration, degree of pain, rate of induced-abortion syndrome, rate of incomplete abortion, menstrual changes and post-operative onset of Asherman's syndrome were observed and compared between 2 groups. The average age, ratio of parous cases, ratio of the cases of first-pregnancy induced abortion were not different between 2 groups (P > 0.05). The amount of hemorrhage bleeding ((4.9 ± 3.2) ml), operative duration ((90.3 ± 12.4) s), degree of pain, rate of induced-abortion syndrome, menstrual changes and the rate of Asherman's syndrome in the EPIA group were all significantly less than those in the CIA group (P < 0.05). However, the rate of incomplete abortion (0.44%) in the EPIA group was significantly higher than that (0.21%) in the CIA group (P < 0.05). EPIA has the advantages of lesser hemorrhage, less pain, shorter operative duration and fewer complications over CIA. Therefore the recovery of EPIA cases is earlier than that of CIA cases. While the risk of incomplete abortion stays high.

Two field isolates of Ureaplasma diversum spp. were used to infect heifers at the time of insemination in a preliminary study to observe the effect of infection on early pregnancy. M84-14c-1 was a field isolate from a bull's prepuce typed by immunofluorescence to be similar to U. diversum strain T-44 (Group C). M84-477c-4 was a field isolate from bovine semen typed by immunofluorescence to be similar to U. diversum strain T-288 (Group A). All three heifers infected with M84-477c-4 had a mild granular vulvitis at some time during the trial. None was pregnant when slaughtered 27 days after infection. The result of infection with M84-14c-1, a preputial isolate, was not consistent. One heifer had no infection and a normal pregnancy, one heifer was infected with an abnormal pregnancy, and one heifer was open but ureaplasmas were not detected until day 17 of the trial.

Background Cytomegalovirus (CMV) is the most prevalent congenital viral infection and thus places an enormous disease burden on newborn infants. Seroprevalence of maternal antibodies to CMV due to CMV exposure prior to pregnancy is currently the most important protective factor against congenital CMV disease. The aim of this study was to identify potential predictors, and to develop and evaluate a risk-predicting model for the maternal CMV serostatus in early pregnancy. Methods Maternal and paternal background information, as well as maternal CMV serostatus in early pregnancy from 882 pregnant women were analyzed. Women were divided into two groups based on their CMV serostatus, and were compared using univariate analysis. To predict serostatus based on epidemiological baseline characteristics, a multiple logistic regression model was calculated using stepwise model selection. Sensitivity and specificity were analyzed using ROC curves. A nomogram based on the model was developed. Results 646 women were CMV seropositive (73.2%), and 236 were seronegative (26.8%). The groups differed significantly with respect to maternal age (p = 0.006), gravidity (p<0.001), parity (p<0.001), use of assisted reproduction techniques (p = 0.018), maternal and paternal migration background (p<0.001), and maternal and paternal education level (p<0.001). ROC evaluation of the selected prediction model revealed an area under the curve of 0.83 (95%CI: 0.8–0.86), yielding sensitivity and specificity values of 0.69 and 0.86, respectively. Conclusion We identified predictors of maternal CMV serostatus in early pregnancy and developed a risk-predicting model based on baseline epidemiological characteristics. Our findings provide easy accessible information that can influence the counseling of pregnant woman in terms of their CMV-associated risk. PMID:26693714

The kidney in pregnancy: A journey of three decades.

PubMed

Prakash, J

2012-05-01

The spectrum of kidney disease occurring during pregnancy includes preeclampsia, hypertensive disorders of pregnancy, urinary tract infection, acute kidney injury, and renal cortical necrosis (RCN). Preeclampsia affects approximately 3-5% of pregnancies. We observed preeclampsia in 5.8% of pregnancies, and 2.38% of our preeclamptic women developed eclampsia. Severe preeclampsia and the eclampsia or hemolysis, elevated liver enzymes levels, and low platelets count (HELLP) syndrome accounted for about 40% of cases of acute kidney injury (AKI) in pregnancy. Preeclampsia/eclampsia was the cause of acute renal failure (ARF) in 38.3% of the cases. Preeclampsia was the most common (91.7%) cause of hypertension during pregnancy, and chronic hypertension was present in 8.3% of patients. We observed urinary tract infection (UTI) in 9% of pregnancies. Sepsis resulting from pyelonephritis can progress to endotoxic shock, disseminated intravascular coagulation, and AKI. The incidence of premature delivery and low birth weight is higher in women with UTI. The incidence of AKI in pregnancy with respect to total ARF cases has decreased over the last 30 years from 25% in 1980s to 5% in 2000s. Septic abortion-related ARF decreased from 9% to 3%. Prevention of unwanted pregnancy and avoidance of septic abortion are key to eliminate abortion-associated ARF in early pregnancy. The two most common causes of ARF in third trimester and postpartum periods were puerperal sepsis and preeclampsia/HELLP syndrome. Pregnancy-associated thrombotic thrombocytopenic purpura/hemolytic uremic syndrome and acute fatty liver of pregnancy were rare causes of ARF. Despite decreasing incidence, AKI remains a serious complication during pregnancy.

Continuous brachial plexus catheters are often used to decrease pain following elbow surgery. This investigation aimed to assess the rate of early failure of infraclavicular (IC) and axillary (AX) nerve catheters following elbow surgery. Retrospective study. Postoperative recovery unit and inpatient hospital floor. 328 patients who received IC or AX nerve catheters and underwent elbow surgery were identified by retrospective query of our institution's database. Data collected included unplanned catheter dislodgement, catheter replacement rate, postoperative pain scores, and opioid administration on postoperative day 1. Catheter failure was defined as unplanned dislodging within 24 h of placement or requirement for catheter replacement and evaluated using a covariate adjusted model. 119 IC catheters and 209 AX catheters were evaluated. There were 8 (6.7%) failed IC catheters versus 13 (6.2%) failed AX catheters. After adjusting for age, BMI, and gender there was no difference in catheter failure rate between IC and AX nerve catheters (p = 0.449). These results suggest that IC and AX nerve catheters do not differ in the rate of early catheter failure, despite differences in anatomic location and catheter placement techniques. Both techniques provided effective postoperative analgesia with median pain scores < 3/10 for patients following elbow surgery. Reasons other than rate of early catheter failure should dictate which approach is performed. Copyright © 2018. Published by Elsevier Inc.

Objective The objective of the study was to characterize the developmental sequence of pre- and postnatal risk factors for inattention-hyperactivity symptoms in preschoolers. Materials and Methods Longitudinal data came from a French population based birth cohort study (EDEN; N = 1311 mother-child pairs followed from the pregnancy onwards). Inattention-hyperactivity symptoms were assessed with the Strengths and Difficulties Questionnaire when participating children were 3 years of age. Potential risk factors were classified in four domains (fetal exposures and child somatic characteristics, child temperament, child neurodevelopmental status, psychosocial environment) and four periods (before pregnancy, prenatal/birth, infancy, toddlerhood). Their role as potential moderator or mediator was tested with path analysis to determine the developmental sequence. Results A low family socioeconomic status before pregnancy was the main environmental risk factor for inattention-hyperactivity symptoms at 3 years, and its effect occurred via two pathways. The first was a risk pathway, where lower SES was associated with higher maternal depression and anxiety during pregnancy; then to higher maternal and child distress and dysregulation in infancy; and in turn to higher levels of inattention-hyperactivity at 3 years. The second was a protective pathway, where higher SES was associated with longer duration of breastfeeding during infancy; then to better child neurodevelopmental status in toddlerhood; and in turn to lower levels of inattention-hyperactivity at 3 years. Discussion This study identified psychosocial factors at several developmental periods that represent potential targets for preventing the emergence of inattention-hyperactivity symptoms in early childhood.

Complicated pregnancies in inherited distal renal tubular acidosis: importance of acid-base balance.

Inherited distal renal tubular acidosis (dRTA) is caused by impaired urinary acid excretion resulting in hyperchloremic metabolic acidosis. Although the glomerular filtration rate (GFR) is usually preserved, and hypertension and overt proteinuria are absent, it has to be considered that patients with dRTA also suffer from chronic kidney disease (CKD) with an increased risk for adverse pregnancy-related outcomes. Typical complications of dRTA include severe hypokalemia leading to cardiac arrhythmias and paralysis, nephrolithiasis and nephrocalcinosis. Several physiologic changes occur in normal pregnancy including alterations in acid-base and electrolyte homeostasis as well as in GFR. However, data on pregnancy in women with inherited dRTA are scarce. We report the course of pregnancy in three women with hereditary dRTA. Complications observed were severe metabolic acidosis, profound hypokalemia aggravated by hyperemesis gravidarum, recurrent urinary tract infection (UTI) and ureteric obstruction leading to renal failure. However, the outcome of all five pregnancies (1 pregnancy each for mothers n. 1 and 2; 3 pregnancies for mother n. 3) was excellent due to timely interventions. Our findings highlight the importance of close nephrologic monitoring of women with inherited dRTA during pregnancy. In addition to routine assessment of creatinine and proteinuria, caregivers should especially focus on acid-base status, plasma potassium and urinary tract infections. Patients should be screened for renal obstruction in the case of typical symptoms, UTI or renal failure. Furthermore, genetic identification of the underlying mutation may (a) support early nephrologic referral during pregnancy and a better management of the affected woman, and (b) help to avoid delayed diagnosis and reduce complications in affected newborns.

Several studies investigating potential adverse effects of the pandemic A(H1N1) vaccine have supported that influenza A(H1N1) vaccination does not increase the risk for major pregnancy and birth adverse outcomes, but little is known about possible adverse effects in offspring of A(H1N1)-vaccinated mothers beyond the perinatal period and into early childhood. To evaluate whether pandemic influenza A(H1N1) vaccination in pregnancy increases the risk for early childhood morbidity in offspring. Register-based cohort study comprising all live-born singleton children in Denmark from pregnancies overlapping the A(H1N1) influenza vaccination campaign in Denmark, from November 2, 2009, to March 31, 2010. From a cohort of 61 359 pregnancies, offspring exposed and unexposed to the influenza A(H1N1) vaccine during pregnancy were matched 1:4 on propensity scores. Vaccination in pregnancy with a monovalent inactivated AS03-adjuvanted split virion influenza A(H1N1)pdm09 vaccine (Pandemrix; GlaxoSmithKline Biologicals). Rate ratios of hospitalization in early childhood until 5 years of age. Hospitalization was defined as (1) first inpatient hospital admission, (2) all inpatient hospital admissions, and (3) first hospital contact for selected diseases, which included individual infectious diseases and individual neurologic, autoimmune, and behavioral conditions. The mean (SD) age at end of follow-up was 4.6 (0.40) years for the 61 359 children included in the study. In the cohort, the mothers of 55 048 children were unvaccinated, 349 mothers were vaccinated in the first trimester, and 5962 mothers were vaccinated in the second or third trimesters. Children exposed in the first trimester were not more likely to be hospitalized in early childhood than unexposed children (hospitalization rates per 1000 person-years, 300.6 for exposed vs 257.5 for unexposed; rate ratio, 1.17; 95% CI, 0.94-1.45). Similarly, children exposed in the second or third trimester were not more likely to

Preventing teen pregnancy through persuasive communications: realities, myths, and the hard-fact truths.

PubMed

Witte, K

1997-04-01

Effective campaigns are desperately needed to combat the serious social problem of teen pregnancy. However, public health campaigns are most often noted for failures, rather than successes. One reason for a campaign failing to have the intended effect is lack of theoretical guidance at the formative evaluation stage. The study reported here is a theoretically-based formative evaluation with inner city teens. Six focus groups were conducted to determine knowledge, attitudes, beliefs, and recommendations for effective campaigns to deter teen pregnancy. The results indicate that campaign messages need to combat positive attitudes toward pregnancy, negative attitudes toward birth control, the perception of personal invulnerability, and emphasize the negative consequences of sexual intercourse. This study's findings also suggest that campaigns with these messages need to start at an early age in order to effectively prevent teen pregnancy.

Pregnancy and renal outcomes in lupus nephritis: an update and guide to management.

Bramham, K; Soh, M C; Nelson-Piercy, C

2012-10-01

Systemic lupus erythematosis (SLE) commonly affects women of child bearing-age, and advances in treatment have resulted in an increasing number of women with renal involvement becoming pregnant. Knowledge of the relationship of the condition with respect to fertility and pregnancy is important for all clinicians involved in the care of women with lupus nephritis because they have complicated pregnancies. Presentation of lupus nephritis can range from mild asymptomatic proteinuria to rapidly progressive renal failure and may occur before, during, or after pregnancy. The timing of diagnosis may influence pregnancy outcome. Pregnancy may also affect the course of lupus nephritis. All pregnancies in women with lupus nephritis should be planned, preferably after more than six-months of quiescent disease. Predictors of poor obstetric outcome include active disease at conception or early pregnancy, baseline poor renal function with Creatinine >100 μmol/L, proteinuria >0.5 g/24 hours, presence of concurrent antiphospholipid syndrome and hypertension. In this review the most recent studies of pregnancies in women with lupus nephritis are discussed and a practical approach to managing women prepregnancy, during pregnancy and post-partum is described.

The objectives of this study were to evaluate embryonic size and survival, plasma progesterone (P4) and pregnancy-specific protein bovine (PSPB) concentrations in early pregnancies (n = 99) following the transfer of one whole (n = 66) or one demi (n = 33) embryo to recipient virgin dairy heifers. The experiment was designed to evaluate the fixed effects of embryo size at transfer (whole or demi embryo) on Day 7 of the estrous cycle (Day 0 = estrus) and P4 supplementation between Days 7 to 19 through an intravaginal device (yes or no) on plasma P4 and PSPB concentrations and on embryo measurements. Plasma P4 concentrations were measured by RIA on Days 0, 7, 14, 19, 21, 25, 35, 42, 49, 56 and 63 of pregnancy and, PSPB concentrations were measured by ELISA on Days 7, 21, 25, 35, 42, 49, 56 and 63. The presence of an embryonic vesicle was detected on Day 25, embryonic/fetal movements and heartbeat were evaluated on Days 42 and 63 and embryo measurements [crown-rump length (CRL) and width at mid body] were obtained on Day 42 through ultrasonography. In non-supplemented pregnancies, Day 42 whole embryos had higher (P < 0.05) CRL and width than demi embryos, but the difference averaged only 1 to 2 mm. In P4 supplemented pregnancies, whole and demi embryos attained a similar size on Day 42 of pregnancy. Embryo size at transfer, early exogenous P4 supplementation and their interactions had no effects (P > 0.05) on plasma P4 concentrations. However, the post-hoc LSD evaluation showed that plasma P4 concentrations on Day 25 were higher (P < 0.001) in whole than in demi embryo derived pregnancies and, that exogenous P4 supplementation increased (P < 0.05) plasma P4 concentrations on Day 19 of pregnancy. The plasma PSPB detection rate on Days 7 to 63 of pregnancy was similar in pregnancies resulting from the transfer of whole and demi embryos. From a total of 93 recipients remaining pregnant until Day 63, plasma PSPB was constantly undetectable on Day 7, was detected in 4% of

The aim of this study was to investigate the association between maternal iron/zinc serum levels and their nutritional intake in early pregnancy with gestational diabetes. The maternal serum zinc/iron levels were measured in 1,033 healthy singleton pregnant women aged 20-35 between 14 and 20 weeks of gestation, within two groups: namely, normal and gestational diabetes, and participants were followed up to 24-28 weeks of gestation. Food frequency questionnaire was used to assess nutritional intakes of iron/zinc. The main outcome was gestational diabetes screened with the 50-g glucose challenge test and diagnosed with oral glucose tolerance test at 24-28 weeks of gestation. Gestational diabetes occurred in 72 (6.96 %) of 1,033 women in study. There was a statistical relationship between early pregnancy maternal serum iron and gestational diabetes, mean (SD), 143.8 (48.7) vs. 112.5 (83.5) μg/dl, P value of <0.0001. There was no statistical significant difference in zinc levels and iron/zinc nutritional intake between groups. The results remained unchanged after using regression model for adjustment of potential risk factors with an adjusted OR of 1.006 (95 % CI 1.002 to 1.009; P = 0.001) for early pregnancy maternal serum iron to cause gestational diabetes. The receiver-operator characteristic curve identified that a maternal serum iron above 100 μg/dl in early pregnancy is the optimum cutoff value for predicting gestational diabetes, which showed a sensitivity and specificity of 80.6 and 50.7 %, respectively. In conclusion, high maternal serum iron in early pregnancy could increase the risk of gestational diabetes. Also, it could be used as a sensitive and specific predictor for gestational diabetes.

Background: Accumulating evidence suggests that long-term anterior cruciate ligament (ACL) deficiency can give rise to an abnormal tibiofemoral relationship and subsequent intra-articular lesions. However, the effects of chronic ACL deficiency (ACLD) on early graft failure after anatomic reconstruction remain unclear. Hypothesis: We hypothesized that patients with long-term ACLD lasting more than 5 years would have a greater rate of early graft failure due to insufficient intraoperative reduction of the tibia and that the preoperative and immediately postoperative abnormal tibiofemoral relationship in the sagittal plane, such as anterior tibial subluxation (ATS), would correlate with the graft status on postoperative magnetic resonance imaging (MRI). Study Design: Cohort study; Level of evidence, 3. Methods: A total of 358 patients who had undergone anatomic ACL reconstruction with hamstring grafts were divided into 5 groups based on chronicity of ACLD: (1) 0 to 6 months, (2) 6 months to 1 year, (3) 1 to 2 years, (4) 2 to 5 years, and (5) longer than 5 years. Preoperatively and immediately postoperatively, lateral radiographs in full extension were taken in all patients to evaluate the tibiofemoral relationship, specifically with regard to ATS, space for the ACL (sACL), and extension angle. All patients underwent MRI at 6 months to reveal graft status. Groups with a high rate of graft failure were further analyzed to compare demographic and radiographic factors between the intact and failure subgroups, followed by multivariate logistic regression analysis to identify predisposing factors. Results: Graft failure without trauma was observed in 4 (1.8%), 0 (0%), 1 (3.7%), 3 (9.7%), and 8 patients (17.7%) in groups 1, 2, 3, 4, and 5, respectively. Of the 76 patients in groups 4 and 5, significant differences were noted between the failure and intact subgroups in preoperative ATS (4.9 vs 2.4 mm, respectively; P < .01), side-to-side differences in sACL (sACL-SSD) (4.7 vs

Interferon-tau (IFN-τ)-induced molecular markers such as ubiquitin-like modifier (ISG15), 2',5'-oligoadenylate synthetase 1 (OAS1) and myxovirus resistance genes (MX1 and MX2) have generated immense attention towards developing diagnostic tools for early diagnosis of pregnancy in bovine. These molecules are expressed at transcriptional level in peripheral nucleated cells. However, their presence in the serum is still a question mark. This study reports sequential changes in expression of MX2 transcript in whole blood and serum MX2 protein level on days 0, 7, 14, 21, 28 and 35 in pregnant (n = 9) buffalo heifers, and on days 0, 7 and 14 in non-inseminated (n = 8) and inseminated non-pregnant (n = 10) control animals. In non-inseminated and inseminated non-pregnant heifers, the differential expression of MX2 transcript and MX2 protein level remained similar between day 7 and 14 post-oestrus. However, in pregnant heifers, on 14th and 28th day post-insemination MX2 transcript was 16.38 ± 1.57 and 28.16 ± 1.91 times upregulated as compared to day 0. Similarly, serum MX2 protein concentration followed analogous trend as MX2 transcript and increased gradually with the progression of pregnancy. Correlation analysis between expression of MX2 transcript and its serum protein level showed a significant positive correlation in pregnant animals, while it was random in other two groups. Therefore, MX2 surge at transcriptional and serum protein level after day 14-28 of pregnancy in buffalo holds potential for its use in early pregnancy detection. © 2016 Blackwell Verlag GmbH.

Objective To assess associations of intimate partner violence (IPV) with pregnancy intendedness and pre-pregnancy contraceptive use among pregnant women in South Asia. Study Design Cross-sectional analyses were conducted using most recent Demographic and Health Surveys (DHS) from Bangladesh, India and Nepal for married, pregnant women aged 15–49 years who responded to IPV assessments specific to current marriage (N=4738). Adjusted logistic and multinomial regression analyses were conducted with pooled data to assess associations of IPV ever (sexual only, physical only, sexual plus physical, none) with the outcomes of pregnancy intendedness (wanted, mistimed or unwanted) and pre-pregnancy contraceptive use (no, traditional, or modern), for the current pregnancy. Results IPV was not associated with a mistimed or unwanted pregnancy. Sexual IPV was associated with pre-pregnancy modern contraceptive use (aOR=2.32, 95% CI=1.24, 4.36); sexual plus physical IPV was associated with pre-pregnancy traditional contraceptive use (aOR=1.85, 95% CI=1.12, 3.07). Post-hoc analysis of reasons for pre-pregnancy contraceptive discontinuation revealed that women with a history of IPV, particularly sexual IPV, had higher prevalence of contraceptive failure (sexual only: 37.3%, sexual plus physical: 30.9%, physical only: 22.6%, no IPV: 13.6%). Conclusion Pregnant women who experienced sexual IPV from husbands were more likely to use contraceptives pre-pregnancy but had no reduced risk unintended pregnancy, possibly due to higher rates of pre-pregnancy contraceptive failure among those with this history. These findings suggest that victims of sexual IPV are able to acquire and use family planning services, but require more support to sustain effective contraceptive use. Implications Family planning services are reaching women affected by sexual IPV, and programs should be sensitive to this concern and the heightened vulnerability to contraceptive failure these women face.

Per- and polyfluoroalkyl substances (PFASs), used in food packaging and stain-resistant coatings, are suspected developmental toxicants that are ubiquitous and persistent in the environment. We measured plasma PFAS concentrations during early pregnancy (median = 9.7 weeks gestation) among 1645 women in the Boston-area Project Viva cohort, recruited during 1999–2002. We used multivariable linear regression to estimate associations of sociodemographic and perinatal predictors, including measures of pregnancy physiology (albumin, glomerular filtration rate (GFR)), with log-transformed plasma PFAS concentrations. Geometric mean concentrations for the four main PFASs, perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), perfluorohexanesulfonate (PFHxS) and perfluorononanoate (PFNA) were 25.4, 5.7, 2.5, and 0.6 ng/mL, respectively, comparable with general U.S. population concentrations during those years. Higher early pregnancy PFAS concentrations were associated with younger age (except PFNA), less educational attainment, nulliparity, no history of breastfeeding and higher prepregnancy body mass index in adjusted models. In addition, lower GFR was associated with 3–4% higher PFAS concentrations and higher albumin was associated with 4–6% higher PFAS concentrations. Our results show associations consistent (parity and breastfeeding) and less consistent (age and education) with previous studies. We also report associations with GFR and albumin, which were strongly related to PFAS concentrations and thus could confound estimates of PFAS–outcome associations in epidemiologic studies.

Little is known about trajectories of PTSD symptoms across the peripartum period in women with trauma histories, specifically those who met lifetime PTSD diagnoses prior to pregnancy. The present study seeks to identify factors that influence PTSD symptom load across pregnancy and early postpartum, and study its impact on postpartum adaptation. The current study is a secondary analysis on pregnant women with a Lifetime PTSD diagnosis (N = 319) derived from a larger community sample who were interviewed twice across pregnancy (28 and 35 weeks) and again at 6 weeks postpartum, assessing socioeconomic risks, mental health, past and ongoing trauma exposure, and adaptation to postpartum. Using trajectory analysis, first we examined the natural course of PTSD symptoms based on patterns across peripartum, and found four distinct trajectory groups. Second, we explored factors (demographic, historical, and gestational) that shape the PTSD symptom trajectories, and examined the impact of trajectory membership on maternal postpartum adaptation. We found that child abuse history, demographic risk, and lifetime PTSD symptom count increased pregnancy-onset PTSD risk, whereas gestational PTSD symptom trajectory was best predicted by interim trauma and labor anxiety. Women with the greatest PTSD symptom rise during pregnancy were most likely to suffer postpartum depression and reported greatest bonding impairment with their infants at 6 weeks postpartum. Screening for modifiable risks (interpersonal trauma exposure and labor anxiety) and /or PTSD symptom load during pregnancy appears critical to promote maternal wellbeing. © 2016 Wiley Periodicals, Inc.

Chlamydia trachomatis heat shock protein 10 (Chsp10) is associated with chronic genital tract infection with C. trachomatis. Chsp10 is homologous to human chaperonin 10 (Cpn10) and early pregnancy factor (EPF), a form of human Cpn10 that is specifically secreted at the start of pregnancy. We investigated cross-reactions between serum anti-Chsp10 antibodies and anti-EPF antibodies in pregnant and nonpregnant patients. Pregnancy was found to be associated with the presence of anti-EPF antibodies, which are specifically induced in pregnant women with a history of C. trachomatis infection, and with the presence of serum anti-Chsp10 antibodies. We also found that infertility was associated with the presence of anti-Chsp10 and anti-EPF antibodies. The HLA class II haplotype DR8 DQ4 was associated with the presence of anti-Chsp10 antibodies but not of anti-EPF antibodies. PMID:12738647

Detection of early pregnancy factor-like activity in women with gestational trophoblastic tumors.

The presence of immunosuppressive early pregnancy factor (EPF) in the maternal serum has so far been associated with gestation. Its presence in the serum of women with gestational trophoblastic tumors was investigated. The results indicate that while EPF activity was detected in the serum of women with choriocarcinoma, no such activity was detected in the serum of women with hydatidiform mole, leading to the novel use of EPF as a marker to distinguish these two clinical situations. Results of the experiments also suggest that EPF moiety present in the maternal serum during pregnancy may be of different molecular entity than that present in the serum of women with choriocarcinoma.

Conventional treatment of obstetric antiphospholipid syndrome fails in approximately 20-30% of pregnant women without any clearly identified risk factor. It is important to identify risk factors that are associated with these treatment failures. This study aimed to assess the impact of risk factors on pregnancy outcomes in women with obstetric antiphospholipid syndrome treated with conventional treatment. We carefully retrospectively selected 106 pregnancies in women with obstetric antiphospholipid syndrome treated with heparin + aspirin. Pregnancy outcomes were evaluated according to the following associated risk factors: triple positivity profile, double positivity profile, single positivity profile, history of thrombosis, autoimmune disease, more than four pregnancy losses, and high titers of anticardiolipin antibodies and/or anti-βeta-2-glycoprotein-I (aβ2GPI) antibodies. To establish the association between pregnancy outcomes and risk factors, a single binary logistic regressions analysis was performed. Risk factors associated with pregnancy loss with conventional treatment were: the presence of triple positivity (OR = 5.0, CI = 1.4-16.9, p = 0.01), high titers of aβ2GPI (OR = 4.4, CI = 1.2-16.1, p = 0.023) and a history of more than four pregnancy losses (OR = 3.5, CI = 1.2-10.0, p = 0.018). The presence of triple positivity was an independent risk factor associated with gestational complications (OR = 4.1, CI = 1.2-13.9, p = 0.02). Our findings reinforce the idea that triple positivity is a categorical risk factor for poor response to conventional treatment.

Vitamin D deficiency is a common problem in reproductive-aged women in the United States. The effect of vitamin D deficiency in pregnancy is unknown, but has been associated with adverse pregnancy outcomes. The objective of this study was to analyze the relationship between vitamin D deficiency in the first trimester and subsequent clinical outcomes. This is a retrospective cohort study. Plasma was collected in the first trimester from 310 nulliparous women with singleton gestations without significant medical problems. Competitive enzymatic vitamin D assays were performed on banked plasma specimens and pregnancy outcomes were collected after delivery. Logistic regression was performed on patients stratified by plasma vitamin D concentration and the following combined clinical outcomes: preeclampsia, preterm delivery, intrauterine growth restriction, gestational diabetes, and spontaneous abortion. Vitamin D concentrations were obtained from 235 patients (mean age 24.3 years, range 18-40 years). Seventy percent of our study population was vitamin D insufficient with a serum concentration less than 30 ng/mL (mean serum concentration 27.6 ng/mL, range 13-71.6 ng/mL). Logistic regression was performed adjusting for age, race, body mass index, tobacco use, and time of year. Adverse pregnancy outcomes included preeclampsia, growth restriction, preterm delivery, gestational diabetes, and spontaneous abortion. There was no association between vitamin D deficiency and composite adverse pregnancy outcomes with an adjusted odds ratio of 1.01 (p value 0.738, 95% confidence intervals 0.961-1.057). Vitamin D deficiency did not associate with adverse pregnancy outcomes in this study population. However, the high percentage of affected individuals highlights the prevalence of vitamin D deficiency in young, reproductive-aged women.

Understanding associations between pregnancy and HIV disease progression is critical to provide appropriate counseling and care to HIV-positive women. From 2006 to 2011, women less than age 40 with incident HIV infection were enrolled in an early HIV infection cohort in Kenya, Rwanda, South Africa, Uganda, and Zambia. Time-dependent Cox models evaluated associations between pregnancy and HIV disease progression. Clinical progression was defined as a single CD4 measurement <200 cells/μl, percent CD4 <14%, or category C event, with censoring at antiretroviral (ART) initiation for reasons other than prevention of mother-to-child transmission (PMTCT). Immunologic progression was defined as two consecutive CD4s ≤350 cells/μl or a single CD4 ≤350 cells/μl followed by non-PMTCT ART initiation. Generalized estimating equations assessed changes in CD4 before and after pregnancy. Among 222 women, 63 experienced clinical progression during 783.5 person-years at risk (8.0/100). Among 205 women, 87 experienced immunologic progression during 680.1 person-years at risk (12.8/100). The association between pregnancy and clinical progression was adjusted hazard ratio [aHR] = 0.7; 95% confidence interval (CI): 0.2, 1.8. The association between pregnancy and immunologic progression was aHR = 1.7; 95% CI: 0.9, 3.3. Models controlled for age; human leukocyte antigen alleles A*03:01, B*45, B*57; CD4 set point; and HIV-1 subtype. CD4 measurements before versus after pregnancies were not different. In this cohort, pregnancy was not associated with increased clinical or immunologic HIV progression. Similarly, we did not observe meaningful deleterious associations of pregnancy with CD4s. Our findings suggest that HIV-positive women may become pregnant without harmful health effects occurring during the pregnancy. Evaluation of longer-term impact of pregnancy on progression is warranted.

To assess the impact of subclinical hypothyroidism (SCH) in women with recurrent early pregnancy loss (REPL). Observational cohort study. REPL program in an academic medical center. 286 women with a history of ≥2 pregnancy losses <10 weeks. From 2004-2007, no treatment for women with SCH (thyroid-stimulating hormone [TSH] >2.5 mIU/L with a normal free thyroxine or free thyroxine index); from 2008 onward, levothyroxine treatment prepregnancy to maintain TSH ≤2.5 mIU/L. Live-birth rate (LBR). The prevalence of SCH was 55 (19%) of 286 in this REPL cohort. The cumulative LBR was 27 (69%) of 39 for women with SCH versus 104 (74%) of 141 for euthyroid women. The per-pregnancy LBR was 34 (49%) of 69 for SCH versus 129 (58%) of 221 for euthyroid women. When the LBR was compared between treated and untreated SCH, the cumulative LBR was 17 (71%) of 24 versus 10 (67%) of 15, respectively. The per-pregnancy LBR for SCH treated versus untreated women was 22 (48%) of 46 versus 12 (52%) of 23, respectively. Although there was a high prevalence of SCH in the REPL cohort, there was no statistically significant difference in the subsequent live-birth rate when comparing women with SCH and euthyroid women, or treated and untreated SCH.

Impact of new society of radiologists in ultrasound early first-trimester diagnostic criteria for nonviable pregnancy.

PubMed

Hu, Maowen; Poder, Liina; Filly, Roy A

2014-09-01

New early first-trimester diagnostic criteria for nonviable pregnancy recommended by the Society of Radiologists in Ultrasound via a multispecialty consensus panel extended the diagnostic size criteria of crown-rump length from 5 to 7 mm for embryos without a heartbeat and mean sac diameter from 16 to 25 mm for "empty" sacs. Our study assessed the potential impact of the new criteria on the number of additional follow-up sonograms these changes would engender. A retrospective study of all first-trimester sonograms in women with first trimester bleeding from 1999 to 2008 was conducted. Everyone included in the study had a visible gestational sac in the uterus. There were no pregnancies of unknown location or ectopic pregnancies included in this study cohort. Pregnancy of unknown location was used to describe cases in which there were no signs of pregnancy inside or outside the uterus on transvaginal sonography despite a positive pregnancy test result. A total of 1013 patients met the inclusion criteria. Seven hundred fifty-two patients (74%) had identifiable embryos, and 261 (26%) did not. Of those with an identifiable embryo, 286 (38%) had no detectable embryonic cardiac activity. The breakdown of crown-rump lengths in this group was as follows: 100 measuring less than 5 mm, 36 measuring 5 to 7 mm, and 150 measuring 7 mm or greater. The breakdown of mean sac diameters in those without a visible embryo was as follows: 120 measuring less than 16 mm, 90 measuring 16 to 25 mm, and 51 measuring 25 mm or greater. When diagnosing a failed pregnancy, there can be no room for error. Only 126 of 1013 early pregnancies threatening to abort (12%) fell into the more conservative zones defined by the new compared to the former size criteria (crown-rump length, 5-7 mm; mean sac diameter, 16-25 mm). Therefore, the potential impact of the new guidelines on follow-up sonograms does not appear inordinate. © 2014 by the American Institute of Ultrasound in Medicine.

The kidney in pregnancy: A journey of three decades

PubMed Central

Prakash, J.

2012-01-01

The spectrum of kidney disease occurring during pregnancy includes preeclampsia, hypertensive disorders of pregnancy, urinary tract infection, acute kidney injury, and renal cortical necrosis (RCN). Preeclampsia affects approximately 3–5% of pregnancies. We observed preeclampsia in 5.8% of pregnancies, and 2.38% of our preeclamptic women developed eclampsia. Severe preeclampsia and the eclampsia or hemolysis, elevated liver enzymes levels, and low platelets count (HELLP) syndrome accounted for about 40% of cases of acute kidney injury (AKI) in pregnancy. Preeclampsia/eclampsia was the cause of acute renal failure (ARF) in 38.3% of the cases. Preeclampsia was the most common (91.7%) cause of hypertension during pregnancy, and chronic hypertension was present in 8.3% of patients. We observed urinary tract infection (UTI) in 9% of pregnancies. Sepsis resulting from pyelonephritis can progress to endotoxic shock, disseminated intravascular coagulation, and AKI. The incidence of premature delivery and low birth weight is higher in women with UTI. The incidence of AKI in pregnancy with respect to total ARF cases has decreased over the last 30 years from 25% in 1980s to 5% in 2000s. Septic abortion-related ARF decreased from 9% to 3%. Prevention of unwanted pregnancy and avoidance of septic abortion are key to eliminate abortion-associated ARF in early pregnancy. The two most common causes of ARF in third trimester and postpartum periods were puerperal sepsis and preeclampsia/HELLP syndrome. Pregnancy-associated thrombotic thrombocytopenic purpura/hemolytic uremic syndrome and acute fatty liver of pregnancy were rare causes of ARF. Despite decreasing incidence, AKI remains a serious complication during pregnancy. PMID:23087548

Serum and saliva cortisol relations in adolescents during pregnancy and the early postpartum period.

The purpose of this investigation was to examine: (1) relations between serum and saliva cortisol in adolescents in pregnancy and early postpartum and (2) short-term consistency of serum and saliva cortisol across three samples, 20 minutes apart, as well as the long-term consistency from pregnancy to early postpartum. Pregnant adolescents (n = 40), ages 14 to 19 years, were enrolled in this study. Subjects were seen at 20 weeks gestation or earlier (T1), 34-36 weeks gestation (T2), and 2-3 weeks postpartum (T3). Blood samples were drawn at T1 and T3, at 0, 20, and 40 minutes. Saliva samples were collected across the same 40-minute period at T1, T2, and T3. Spearman rho (rs) correlation coefficients between serum and saliva ranged from 0.72 to 0.77 (T1), and 0.42 to 0.60 (T3) (p < or = 0.05). Short-term consistency between serum cortisol samples was 0.86-0.97 at T1 and 0.60-0.82 at T3. Short-term consistency for saliva cortisol samples was 0.70-0.96 at T1, 0.91-0.95 at T2, and 0.64-0.89 at T3. Long-term consistency (T1 to T3) for serum and saliva cortisol was low. Individual differences as well as dramatic changes in the endocrine environment in pregnancy and the early postpartum period may explain the more moderate serum-saliva correlations in the postpartum period.

The adherens junction is lost during normal pregnancy but not during ovarian hyperstimulated pregnancy.

During early pregnancy in the rat, the luminal uterine epithelial cells (UECs) must transform to a receptive state to permit blastocyst attachment and implantation. The implantation process involves penetration of the epithelial barrier, so it is expected that the transformation of UECs includes alterations in the lateral junctional complex. Previous studies have demonstrated a deepening of the tight junction (zonula occludens) and a reduction in the number of desmosomes (macula adherens) in UECs at the time of implantation. However, the adherens junction (zonula adherens), which is primarily responsible for cell-cell adhesion, has been little studied during early pregnancy. This study investigated the adherens junction in rat UECs during the early stages of normal pregnancy and ovarian hyperstimulated (OH) pregnancy using transmission electron microscopy. The adherens junction is present in UECs at the time of fertilisation, but is lost at the time of blastocyst implantation during normal pregnancy. Interestingly, at the time of implantation after OH, adherens junctions are retained and may impede blastocyst penetration of the epithelium. The adherens junction anchors the actin-based terminal web, which is known to be disrupted in UECs during early pregnancy. However, artificial disruption of the terminal web, using cytochalasin D, did not cause removal of the adherens junction in UECs. This study revealed that adherens junction disassembly occurs during early pregnancy, but that this process does not occur during OH pregnancy. Such disassembly does not appear to depend on the disruption of the terminal web. Copyright © 2015 Elsevier GmbH. All rights reserved.

To determine the risk of congenital toxoplasmosis (CT) and provide early (pre- or postnatal) identification of cases of CT in the absence of systematic screening in pregnancy.I n the presented cross-sectional study, serological criteria were used to date Toxoplasma gondii infection versus conception in 80 pregnant women with fetal abnormalities or referred to as suspected of acute infection, and in 16 women after delivery of symptomatic neonates. A combination of serological, molecular (qPCR), and biological (bioassay) methods was used for prenatal and/or postnatal diagnosis of CT. Most (77.5%) pregnant women were examined in advanced pregnancy. Of all the examined seropositive women (n = 90), infection could not be ruled out to have occurred during pregnancy in 93.3%, of which the majority (69%) was dated to the periconceptual period. CT was diagnosed in 25 cases, of which 17 prenatally and 8 postnatally. Molecular diagnosis proved superior, but the diagnosis of CT based on bioassay in 7 instances and by Western blot in 2 neonates shows that other methods remain indispensable. In the absence of systematic screening in pregnancy, maternal infection is often diagnosed late, or even only when fetal/neonatal infection is suspected. In such situations, use of a complex algorithm involving a combination of serological, biological, and molecular methods allows for prenatal and/or early postnatal diagnosis of CT, but lacks the preventive capacity provided by early maternal treatment.

Abstract To determine the risk of congenital toxoplasmosis (CT) and provide early (pre- or postnatal) identification of cases of CT in the absence of systematic screening in pregnancy. In the presented cross-sectional study, serological criteria were used to date Toxoplasma gondii infection versus conception in 80 pregnant women with fetal abnormalities or referred to as suspected of acute infection, and in 16 women after delivery of symptomatic neonates. A combination of serological, molecular (qPCR), and biological (bioassay) methods was used for prenatal and/or postnatal diagnosis of CT. Most (77.5%) pregnant women were examined in advanced pregnancy. Of all the examined seropositive women (n = 90), infection could not be ruled out to have occurred during pregnancy in 93.3%, of which the majority (69%) was dated to the periconceptual period. CT was diagnosed in 25 cases, of which 17 prenatally and 8 postnatally. Molecular diagnosis proved superior, but the diagnosis of CT based on bioassay in 7 instances and by Western blot in 2 neonates shows that other methods remain indispensable. In the absence of systematic screening in pregnancy, maternal infection is often diagnosed late, or even only when fetal/neonatal infection is suspected. In such situations, use of a complex algorithm involving a combination of serological, biological, and molecular methods allows for prenatal and/or early postnatal diagnosis of CT, but lacks the preventive capacity provided by early maternal treatment.

Objective Vitamin D deficiency is a common problem in reproductive-aged women in the United States. The effect of vitamin D deficiency in pregnancy is unknown, but has been associated with adverse pregnancy outcomes. The objective of this study was to analyze the relationship between vitamin D deficiency in the first trimester and subsequent clinical outcomes. Study Design This is a retrospective cohort study. Plasma was collected in the first trimester from 310 nulliparous women with singleton gestations without significant medical problems. Competitive enzymatic vitamin D assays were performed on banked plasma specimens and pregnancy outcomes were collected after delivery. Logistic regression was performed on patients stratified by plasma vitamin D concentration and the following combined clinical outcomes: preeclampsia, preterm delivery, intrauterine growth restriction, gestational diabetes, and spontaneous abortion. Results Vitamin D concentrations were obtained from 235 patients (mean age 24.3 years, range 18-40 years). Seventy percent of our study population was vitamin D insufficient with a serum concentration less than 30 ng/mL (mean serum concentration 27.6 ng/mL, range 13-71.6 ng/mL). Logistic regression was performed adjusting for age, race, body mass index, tobacco use, and time of year. Adverse pregnancy outcomes included preeclampsia, growth restriction, preterm delivery, gestational diabetes, and spontaneous abortion. There was no association between vitamin D deficiency and composite adverse pregnancy outcomes with an adjusted odds ratio of 1.01 (p value 0.738, 95% confidence intervals 0.961-1.057). Conclusion Vitamin D deficiency did not associate with adverse pregnancy outcomes in this study population. However, the high percentage of affected individuals highlights the prevalence of vitamin D deficiency in young, reproductive-aged women. PMID:25898021

Children exposed to maternal depression during pregnancy and in the postnatal period are at increased risk of a range of health, wellbeing and development problems. However, few studies have examined the course of maternal depressive symptoms in the perinatal period and beyond on children's wellbeing. The present study aimed to explore the relationship between both the severity and chronicity of maternal depressive symptoms across the early childhood period and children's emotional-behavioural difficulties at 4 years of age. Data from over 1,085 mothers and children participating in a large Australian prospective pregnancy cohort were used. Latent class analysis identified three distinct trajectories of maternal depressive symptoms from pregnancy to 4 years postpartum: (1) no or few symptoms (61%), (2) persistent subclinical symptoms (30%), and (3) increasing and persistently high symptoms (9%). Regression analyses revealed that children of mothers experiencing subclinical and increasing and persistently high symptoms were at least two times more likely to have emotional-behavioural difficulties than children of mothers reporting minimal symptoms, even after accounting for known risk factors for poor outcomes for children. These findings challenge policy makers and health professionals to consider how they can tailor care and support to mothers experiencing a broader spectrum of depressive symptoms across the early childhood period, to maximize opportunities to improve both short-and long-term maternal and child health outcomes.

Among domestic dog breeders it is common practice to transfer a domestic dog bitch out of her home environment for mating, bringing her back after the mating. If the home environment contains a male, who is not the father of the foetuses, there is a potential risk of future infanticide. We collected 621 records on mating of 249 healthy bitches of 11 breed-types. The highest proportion of successful pregnancies following mating occurred in bitches mated within their home pack and remaining there. Bitches mated elsewhere and then returned to a home containing at least one male had substantially lower incidence of maintained pregnancy in comparison with bitches mated by a home male. After returning home, housing affected strongly the frequency of pregnancy success. Bitches mated elsewhere but released into a home pack containing a home male were four times more likely to maintain pregnancy than bitches which were housed individually after returning home. Suppression of pregnancy in situations where a bitch is unable to confuse a home male about parentage may be seen as an adaptation to avoid any seemingly unavoidable future loss of her progeny to infanticide after birth and thus to save energy.

To estimate the association between serum 25-hydroxyvitamin D concentrations and maternal hyperglycaemia (post-load glucose concentration ≥ 7.5 mmol/l). Pregnant women (n = 429; 61% black, 36% obese, 45% smokers) enrolled in a cohort study at <16 weeks gestation. Non-fasting blood samples were assayed for serum 25-hydroxyvitamin D at enrolment. At 24-28 weeks gestation, maternal hyperglycaemia was determined using a 50-g 1-h oral glucose challenge test. A total of 67% of women had 25-hydroxyvitamin D concentrations < 50 nmol/l and 11% had maternal hyperglycaemia. Among smokers, each 23-nmol/l increase in serum 25-hydroxyvitamin D was associated with a reduction in the odds of maternal hyperglycaemia [odds ratio: 0.30 (95% CI: 0.13, 0.68)] after adjustment for parity, race/ethnicity, age, pre-pregnancy BMI, marital status, income, family history of diabetes, and gestational age of gestational diabetes mellitus screening. Among non-smokers, we found no association between early pregnancy vitamin D status and maternal hyperglycaemia. Smoking status may modify the relationship between poor maternal vitamin D status and maternal hyperglycaemia. © 2013 The Authors. Diabetic Medicine © 2013 Diabetes UK.

The researchers' aim was to examine whether it was better to predict new-onset postpartum depression (PPD) during pregnancy or immediately after childbirth. A prospective study conducted in Croatia followed women (N = 272) from the third trimester of pregnancy through the early postpartum period (within the first 3 postpartum days), to 6 weeks postpartum. Questionnaires on depression, anxiety, stress, coping, self-esteem, and social support were administered. Through regression analyses we showed that PPD symptoms could be equally predicted by variables from pregnancy (30.3%) and the early postpartum period (34.0%), with a small advantage of PPD prediction in the early postpartum period.

Objective To determine the interrelationships during early pregnancy of complement-activation fragments Bb, C3a and sC5b-9, and angiogenesis-related factors placental growth factor (PiGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng), and their associations with pre-eclampsia. Design Prospective cohort study. Setting Denver complement study (June 2005–June 2008). Population A total of 668 pregnant women with singleton gestations, recruited between 10 and 15 weeks of gestation. Methods Using univariable and multivariable logistic regression analysis, concentrations of complement-activation fragments and angiogenesis-related factors were compared between 10 and 15 weeks of gestation in women who subsequently did or did not develop pre-eclampsia. Interrelationships between these variables were tested using the non-parametric Spearman rank correlation coefficient. Main outcome measure Pre-eclampsia. The association of complement-activation fragments and angiogenesis-related factors with obesity was also examined. Results The mean (±SD) levels of complement Bb in early pregnancy among women who did and did not develop pre-eclampsia were 0.84 (±0.26) µg/ml and 0.69 (±0.2) µg/ml, respectively (P = 0.001). Concentrations of PiGF were significantly (P = 0.01) lower (31 ± 12 pg/ml) in early pregnancy in the pre-eclamptic group of women, as compared with the normotensive group (39 ± 32 pg/ml). The adjusted odds ratio (AOR) of Bb and PiGF were 2.1 (CI = 1.4–3.1, P < 0.0003) and 0.2 (CI = 0.07–0.7, P = 0.01), respectively. There was no significant difference in the levels of C3a, sC5b-9, sFlt-1 and sEng in early pregnancy among women who developed pre-eclampsia, compared with women who remained normotensive during pregnancy. Higher levels of Bb (P = 0.0001) and C3a (P = 0.03), and lower levels of sFlt-1 (P = 0.0002) and sEng (P = 0.0001) were found among women with obesity, compared with non-obese controls.

In this contribution we describe the accelerated creep stage and early warning system of a 210'000 m3 rock slope failure that occurred in May 2012 above the village of Preonzo (Swiss Alps). The very rapid failure occurred from a larger and retrogressive instability in high-grade metamorphic ortho-gneisses and amphibolites with a total volume of about 350'000 m3 located at an alpine meadow called Alpe di Roscioro. This instability showed clearly visible signs of movements since 1989 and accelerated creep with significant hydro-mechanical forcing since about 1999. Because the instability at Preonzo threatened a large industrial facility and important transport routes a cost-effective early warning system was installed in 2010. The alarm thresholds for pre-alarm, general public alarm and evacuation were derived from 10 years of continuous displacement monitoring with crack extensometers and an automated total station. These thresholds were successfully applied to evacuate the industrial facility and close important roads a few days before the catastrophic slope failure of May 15th, 2012. The rock slope failure occurred in two events, exposing a planar rupture plane dipping 42° and generating deposits in the mid-slope portion with a travel angle of 38°. Two hours after the second rockslide, the fresh colluvial deposits became reactivated in a devastating de-bris avalanche reaching the foot of the slope.

There has been a growing interest in the role played by antioxidant enzymes in the regulation of endometrial function in mammals. However, little is known about enzymatic antioxidative pathways involved in conditioning the cyclic and early pregnant endometrium for conceptus attachment and implantation in domestic ruminants. We aimed to investigate changes in activities of superoxide dismutase 1 and 2 (SOD1, SOD2), glutathione peroxidase (GPX), glutathione reductase (GR) and catalase (CAT) in sheep caruncles (CAR) and intercaruncles (ICAR) endometrial tissues of cyclic and early pregnant ewes. Irrespective of day of cycle or pregnancy, CAR demonstrated higher activities of SOD1 and SOD2 than in ICAR. On day 12 of the estrous cycle, ICAR demonstrated higher activity of GPX and GR than in CAR tissues. On days 12 and 16 the estrous cycle, ICAR demonstrated higher activity of CAT than in CAR. CAR demonstrated higher activity of GPX on day 18 than on days 4, 8, 12 and 16 of the estrous cycle. CAR demonstrated higher activity of CAT on day 18 than on days 4, 8, 12 and 16 of the estrous cycle. ICAR demonstrated higher activity of CAT on day 18 than on days 4, 8, and 16 of the estrous cycle. The activity of CAT in ICAR increased from days 4 and 8 to day 12 of the estrous cycle. The activity of SOD2 in CAR increased from day 16 to day 18 of pregnancy. On day 12 of pregnancy, CAR demonstrated higher activity of GPX than in ICAR. On day 16 of pregnancy, ICAR demonstrated higher activity of GPX than in CAR. The activity of GPX in ICAR increased from day 12 to day 16 of pregnancy. The activity of GPX in CAR increased from day 16 to day 18 of pregnancy. The activity of GR in CAR and ICAR increased from days 12 and 16 to day 18 of pregnancy. On days 16 and 18 of pregnancy, ICAR demonstrated higher activity of CAT than in CAR. The activity of CAT in CAR decreased from day 12 to days 16 and 18 of pregnancy. The activity of CAT in ICAR decreased from day 12 to day 16 of pregnancy and

Termination of pregnancy at very early gestation without visible yolk sac on ultrasound.

Requests for termination of pregnancy (TOP) at very early gestation (≤6 weeks) can prove challenging for abortion services as the ultrasound feature usually accepted as definitive evidence of an intrauterine pregnancy (IUP), the presence of a yolk sac within a gestational sac, may not yet be evident. In 2011 the Edinburgh TOP service introduced a protocol permitting women to proceed to treatment without further investigations provided that ultrasound showed the features of an eccentrically placed gestational sac (≥3 mm) with a decidual reaction, and there were no signs, symptoms or risk factors for ectopic pregnancy. A retrospective audit was conducted of outcomes of women presenting for TOP at ≤6 weeks' gestation over a 2-year period using the hospital computerised database. A total of 1155 women presented for TOP with an ultrasound gestational age of ≤6 weeks. Of these, 1030 (89%) had ultrasound evidence of a yolk sac. Eighty-seven women (7.5%) had an eccentrically placed gestational sac with a decidual reaction. All 87 women fulfilled our criteria to proceed to medical TOP, and 66 did so. In the remaining 21 cases, further investigations were performed before they proceeded to medical TOP. Two (0.17%) medical TOPs failed, both in women whose initial ultrasound had shown a yolk sac. Women with ultrasound features consistent with a very early IUP (≥3 mm eccentrically placed gestational sac with a decidual reaction) and without signs, symptoms or risk factors for ectopic pregnancy can proceed directly to medical TOP without the need for delay for further ultrasonography.

We investigated whether it was possible to predict the prognosis of fetuses with cystic hygroma in early pregnancy based on the degree of neck thickening. We retrospectively analyzed 57 singleton pregnancies with fetuses with cystic hygroma who were examined before the 22nd week of pregnancy. The fetuses were categorized according to the outcome, structural abnormalities at birth, and chromosomal abnormalities. Here, we proposed a new sonographic predictor with which we assessed neck thickening by dividing the width of the neck thickening by the biparietal diameter, which is expressed as the cystic hygroma width/biparietal diameter ratio. The median cystic hygroma width/biparietal diameter ratio in the intrauterine fetal death group (0.51) was significantly higher than that in the live birth group (0.27). No significant difference in the median cystic hygroma width/biparietal diameter ratio was found between the structural abnormalities group at birth and the no structural abnormalities group, and no significant difference in the median cystic hygroma width/biparietal diameter ratio was found between the chromosomal abnormality group and the no chromosomal abnormality group. We used receiver operating characteristic analysis to evaluate the cystic hygroma width/biparietal diameter ratio to predict intrauterine fetal death. When the cystic hygroma width/biparietal diameter ratio cut-off value was 0.5, intrauterine fetal death could be predicted with a sensitivity of 52.9% and a specificity of 100%. It is possible to predict intrauterine fetal death in fetuses with cystic hygroma in early pregnancy if cystic hygroma width/biparietal diameter ratio is measured. However, even if cystic hygroma width/biparietal diameter ratio is measured, predicting the presence or absence of a structural abnormality at birth or a chromosomal abnormality is difficult. © 2018 Japanese Teratology Society.

The influence of microstructure on the probability of early failure in aluminum-based interconnects

NASA Astrophysics Data System (ADS)

Dwyer, V. M.

2004-09-01

For electromigration in short aluminum interconnects terminated by tungsten vias, the well known "short-line" effect applies. In a similar manner, for longer lines, early failure is determined by a critical value Lcrit for the length of polygranular clusters. Any cluster shorter than Lcrit is "immortal" on the time scale of early failure where the figure of merit is not the standard t50 value (the time to 50% failures), but rather the total probability of early failure, Pcf. Pcf is a complex function of current density, linewidth, line length, and material properties (the median grain size d50 and grain size shape factor σd). It is calculated here using a model based around the theory of runs, which has proved itself to be a useful tool for assessing the probability of extreme events. Our analysis shows that Pcf is strongly dependent on σd, and a change in σd from 0.27 to 0.5 can cause an order of magnitude increase in Pcf under typical test conditions. This has implications for the web-based two-dimensional grain-growth simulator MIT/EmSim, which generates grain patterns with σd=0.27, while typical as-patterned structures are better represented by a σd in the range 0.4 - 0.6. The simulator will consequently overestimate interconnect reliability due to this particular electromigration failure mode.

Early-life factors can be associated with future health outcomes and are often measured by maternal recall. We used data from the North Carolina Early Pregnancy Study and Follow-up to characterize long-term maternal recall. We used data from the Early Pregnancy Study as the gold standard to evaluate the accuracy of prepregnancy weight, early pregnancy behaviors, symptoms and duration of pregnancy, and child's birthweight reported at follow-up, for 109 women whose study pregnancies had resulted in a live birth. Most (81%) participants reported a prepregnancy weight at follow-up that correctly classified them by BMI category. Women reported experiencing pregnancy symptoms later at follow-up than what they reported in the Early Pregnancy Study. Accuracy of reporting of early pregnancy behaviors varied based on exposure. Overall, women who had abstained from a behavior were more likely to be classified correctly. Sensitivity of reporting was 0.14 for antibiotics, 0.30 for wine, 0.71 for brewed coffee, and 0.82 for vitamins. Most misclassification at follow-up was due to false-negative reporting. Among women who gave birth to singletons, 94% could report their child's correct birthweight within ½ pound and 86% could report duration of pregnancy within 7 days at follow-up. Self-report of prepregnancy weight, duration of pregnancy, and child's birthweight after almost 30 years was good, whereas self-reported pregnancy-related exposures resulted in higher levels of reporting error. Social desirability appeared to influence women's report of their behaviors at follow-up. Self-reported assessment of confidence in the recalled information was unrelated to accuracy.

Data regarding the prevalence and predictors of vitamin D deficiency during early pregnancy are limited. This study aims to fill this gap. A total of 578 Saudi women in their 1st trimester of pregnancy were recruited between January 2014 and December 2015 from three tertiary care antenatal clinics in Riyadh, Saudi Arabia. Information collected includes socio-economic, anthropometric, and biochemical data, including serum vitamin D (25(OH)D) levels, intake of calcium and vitamin D, physical activity, and sun exposure indices. Pregnant women with 25(OH)D levels <50 nmol/L were considered vitamin D deficient. The majority of participants (n = 468 (81%)) were vitamin D deficient. High levels of indoor activity, whole body clothing, multiparity, total cholesterol/HDL ratio(>3.5), low HDL-cholesterol, and living in West Riyadh were significant independent predictors for vitamin D deficiency, with odds ratios (ORs) (95% confidence interval) of 25.4 (5.5–117.3), 17.8 (2.3–138.5), 4.0 (1.7–9.5), 3.3 (1.4–7.9), 2.8 (1.2–6.4), and 2.0 (1.1–3.5), respectively. Factors like increased physical activity, sun exposure at noon, sunrise or sunset, high educational status, and residence in North Riyadh were protective against vitamin D deficiency with ORs 0.2 (0.1–0.5); 0.2 (0.1–0.6); 0.3 (0.1–0.9); and 0.4 (0.2–0.8), respectively. All ORs were adjusted for age, BMI, sun exposure, parity, summer season, vitamin D intake, multivitamin intake, physical activity, education, employment, living in the north, and coverage with clothing. In conclusion, the prevalence of vitamin D deficiency among Saudi women during early pregnancy was high (81%). Timely detection and appropriate supplementation with adequate amounts of vitamin D should reduce the risks of vitamin D deficiency and its complications during pregnancy. PMID:29662044

Women with hyperthyroidism in pregnancy have increased risks of miscarriage, stillbirth, preterm birth, and intrauterine growth restriction; and they can develop severe pre-eclampsia or placental abruption. To identify interventions used in the management of hyperthyroidism pre-pregnancy or during pregnancy and to ascertain the impact of these interventions on important maternal, fetal, neonatal and childhood outcomes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2013). We planned to include randomised controlled trials, quasi-randomised controlled trials, and cluster-randomised trials comparing antithyroid interventions for hyperthyroidism pre-pregnancy or during pregnancy with another intervention or no intervention (placebo or no treatment). Two review authors assessed trial eligibility and planned to assess trial quality and extract the data independently. No trials were included in the review. As we did not identify any eligible trials, we are unable to comment on implications for practice, although early identification of hyperthyroidism before pregnancy may allow a woman to choose radioactive iodine therapy or surgery before planning to have a child. Designing and conducting a trial of antithyroid interventions for pregnant women with hyperthyroidism presents formidable challenges. Not only is hyperthyroidism a relatively rare condition, both of the two main drugs used have potential for harm, one for the mother and the other for the child. More observational research is required about the potential harms of methimazole in early pregnancy and about the potential liver damage from propylthiouracil.

Modern techniques for the treatment of acromioclavicular (AC) joint dislocations have largely centered on free tendon graft reconstructions. Recent biomechanical studies have demonstrated that an anatomic reconstruction with 2 clavicular bone tunnels more closely matches the properties of native coracoclavicular (CC) ligaments than more traditional techniques. No study has analyzed tunnel position in regard to risk of early failure. To evaluate the effect of clavicular tunnel position in CC ligament reconstruction as a risk of early failure. Case series; Level of evidence, 4. A retrospective review was performed of a consecutive series of CC ligament reconstructions performed with 2 clavicular bone tunnels and a free tendon graft. The population was largely a young, active-duty military group of patients. Radiographs were analyzed for the maintenance of reduction and location of clavicular bone tunnels using a picture archiving and communication system. The distance from the lateral border of the clavicle to the center of each bone tunnel was divided by the total clavicular length to establish a ratio. Medical records were reviewed for operative details and functional outcome. Failure was defined as loss of intraoperative reduction. The overall failure rate was 28.6% (8/28) at an average of 7.4 weeks postoperatively. Comparison of bone tunnel position showed that medialized bone tunnels were a significant predictor for early loss of reduction for the conoid (a ratio of 0.292 vs 0.248; P = .012) and trapezoid bone tunnels (a ratio of 0.171 vs 0.128; P = .004); this correlated to an average of 7 to 9 mm more medial in the reconstructions that failed. Reconstructions performed with a conoid ratio of ≥0.30 were significantly more likely to fail (5/5, 100%) than were those performed lateral to a ratio of 0.30 (3/23, 13.0%) (P < .01). There were no failures when the conoid ratio was <0.25 (0/10, 0%). Conoid tunnel placement was also statistically significant for

The objective of this study was to compare expression of estrogen receptor alpha (ER-α), β (ER-β), progesterone receptor (PR), as well as prostaglandin E2 type 2 (EP2) and 4 (EP4) receptors in the equine myometrium and endometrium during estrus, diestrus and early pregnancy. Tissues were collected during estrus, diestrus, and early pregnancy. Transcripts for ER-α (ESR1), ER-β (ESR2), PR (PGR), EP2 (PTGER2) and EP4 (PTGER4) were quantified by qPCR. Immunohistochemistry was used to localize ER-α, ER-β, PR, EP2 and EP4. Differences in transcript in endometrium and myometrium were compared by the ΔΔCT method. Expression for ESR1 (P<0.05) tended to be higher during estrus than diestrus in the endometrium (P=0.1) and myometrium (P=0.06). In addition, ESR1 expression was greater during estrus than pregnancy (P<0.05) in the endometrium and tended to be higher in estrus compared to pregnancy in the myometrium (P=0.1). Expression for PGR was greater (P<0.05) in the endometrium during estrus and diestrus than during pregnancy. In the myometrium, PGR expression was greater in estrus than pregnancy (P=0.05) and tended to be higher during diestrus in relation to pregnancy (P=0.07). There were no differences among reproductive stages in ESR2, PTGER2 and PTGER4 mRNA expression (P>0.05). Immunolabeling in the endometrium appeared to be more intense for ER-α during estrus than diestrus and pregnancy. In addition, immunostaining for PR during pregnancy appeared to be more intense in the stroma and less intense in glands and epithelium compared to estrus and diestrus. EP2 immunoreactivity appeared to be more intense during early pregnancy in both endometrium and myometrium, whereas weak immunolabeling for EP4 was noted across reproductive stages. This study demonstrates differential regulation of estrogen receptor (ER) and PR in the myometrium and endometrium during the reproductive cycle and pregnancy as well as abundant protein expression of EP2 in the endometrium and

Purpose REtard de Croissance Intra-uterin et PALudisme (RECIPAL) is an original preconceptional cohort designed to assess the consequences of malaria during the first trimester of pregnancy, which is a poorly investigated period in Africa and during which malaria may be detrimental to the fetus. Participants For this purpose, a total of 1214 women of reproductive age living in Sô-Ava and Akassato districts (south Benin) were followed up monthly from June 2014 to December 2016 until 411 of them became pregnant. A large range of health determinants was collected both before and during pregnancy from the first weeks of gestation to delivery. Five Doppler ultrasound scans were performed for early dating of the pregnancy and longitudinal fetal growth assessment. Findings to date Pregnant women were identified at a mean of 6.9 weeks of gestation (wg). Preliminary results confirmed the high prevalence of malaria in the first trimester of pregnancy, with more than 25.4% of women presenting at least one microscopic malarial infection during this period. Most infections occurred before six wg. The prevalence of low birth weight, small birth weight for gestational age (according to INTERGROWTH-21st charts) and preterm birth was 9.3%, 18.3% and 12.6%, respectively. Future plans REtard de Croissance Intra-uterin et PALudisme (RECIPAL) represents at this time a unique resource that will provide information on multiple infectious (including malaria), biological, nutritional and environmental determinants in relation to health outcomes in women of reproductive age, pregnant women and their newborns. It will contribute to better define future recommendations for the prevention of malaria in early pregnancy and maternal malnutrition in Africa. It confirms that it is possible to constitute a preconceptional pregnancy cohort in Africa and provides valuable information for researchers starting cohorts in the future. PMID:29317419

Maternal smoking during pregnancy (MSDP) has been reported to be associated with impaired measures of cognitive function, but it remains unclear whether exposure to MSDP has an impact upon offspring school performance. We examined the association between MSDP and failure of the Criterion-Referenced Competency Tests (CRCT) among Georgia first grade students. A retrospective cohort was created by deterministically linking 331 531 children born in Georgia from 1998 to 2002 (inclusive) to their individual CRCT education records from 2005 to 2009. We evaluated the association between MSDP (yes/no) and failure of the CRCT Reading, English/Language Arts (ELA), and Mathematics tests, with adjustment for maternal and child sociodemographic characteristics and birth outcomes. Log-binomial models estimated the risk ratios and 95% confidence intervals. Conditional models were fitted to paired sibling data. MSDP was associated with CRCT failure with an adjusted risk ratios for Reading: 1.16 [95% CI 1.12, 1.21]; ELA: 1.12 [95%CI 1.10, 1.15]; and Mathematics: 1.13 [95%CI 1.10, 1.16]. The association remained significant in paired sibling analyses. MSDP may have independent long-term effects on offspring school performance, which does not appear to be through smoking-related adverse birth outcomes. © 2013 Blackwell Publishing Ltd.

Background: Understanding associations between pregnancy and HIV disease progression is critical to provide appropriate counseling and care to HIV-positive women. Methods: From 2006 to 2011, women less than age 40 with incident HIV infection were enrolled in an early HIV infection cohort in Kenya, Rwanda, South Africa, Uganda, and Zambia. Time-dependent Cox models evaluated associations between pregnancy and HIV disease progression. Clinical progression was defined as a single CD4 measurement <200 cells/μl, percent CD4 <14%, or category C event, with censoring at antiretroviral (ART) initiation for reasons other than prevention of mother-to-child transmission (PMTCT). Immunologic progression was defined as two consecutive CD4s ≤350 cells/μl or a single CD4 ≤350 cells/μl followed by non-PMTCT ART initiation. Generalized estimating equations assessed changes in CD4 before and after pregnancy. Results: Among 222 women, 63 experienced clinical progression during 783.5 person-years at risk (8.0/100). Among 205 women, 87 experienced immunologic progression during 680.1 person-years at risk (12.8/100). The association between pregnancy and clinical progression was adjusted hazard ratio [aHR] = 0.7; 95% confidence interval (CI): 0.2, 1.8. The association between pregnancy and immunologic progression was aHR = 1.7; 95% CI: 0.9, 3.3. Models controlled for age; human leukocyte antigen alleles A*03:01, B*45, B*57; CD4 set point; and HIV-1 subtype. CD4 measurements before versus after pregnancies were not different. Conclusions: In this cohort, pregnancy was not associated with increased clinical or immunologic HIV progression. Similarly, we did not observe meaningful deleterious associations of pregnancy with CD4s. Our findings suggest that HIV-positive women may become pregnant without harmful health effects occurring during the pregnancy. Evaluation of longer-term impact of pregnancy on progression is warranted. PMID:27893488

Pregnancy luteoma is a rare non neoplastic condition of the ovary. It is usually asymptomatic and found incidentally during imaging in pregnancy or during cesarean section. Pregnancy luteoma can also occur after ectopic pregnancy. A 30 year old female presented to G.B. Pant Hospital, Andaman and Nicobar Islands institute of Medical Sciences, Port Blair in October 2015 with abdominal pain. After initial investigations, exploratory laporotomy was done for ruptured ectopic pregnancy. Enlarged ovary was removed along with the ruptured portion of fallopian tube. Histopathological examination revealed solid aggregates of large cells with abundant eosinophilic cytoplasm; diagnosis of pregnancy luteoma was given. It must be considered in the differential diagnosis of ovarian masses in pregnant females that early diagnosis of this entity may avoid unnecessary radical surgery.

Prevention of unintended pregnancies among women living with HIV infection is a strategy recommended by the World Health Organization for prevention of mother-to-child transmission of HIV (PMTCT). We assessed pregnancy intentions and contraceptive use among HIV-positive and HIV-negative women with a recent pregnancy in Zimbabwe. We analyzed baseline data from the evaluation of Zimbabwe's Accelerated National PMTCT Program. Eligible women were randomly sampled from the catchment areas of 157 health facilities offering PMTCT services in five provinces. Eligible women were ≥16 years old and mothers of infants (alive or deceased) born 9 to 18 months prior to the interview. Participants were interviewed about their HIV status, intendedness of the birth, and contraceptive use. Of 8,797 women, the mean age was 26.7 years, 92.8% were married or had a regular sexual partner, and they had an average of 2.7 lifetime births. Overall, 3,090 (35.1%) reported that their births were unintended; of these women, 1,477 (47.8%) and 1,613 (52.2%) were and were not using a contraceptive method prior to learning that they were pregnant, respectively. Twelve percent of women reported that they were HIV-positive at the time of the survey; women who reported that they were HIV-infected were significantly more likely to report that their pregnancy was unintended compared to women who reported that they were HIV-uninfected (44.9% vs. 33.8%, p<0.01). After adjustment for covariates, among women with unintended births, there was no association between self-reported HIV status and lack of contraception use prior to pregnancy. Unmet need for family planning and contraceptive failure contribute to unintended pregnancies among women in Zimbabwe. Both HIV-infected and HIV-uninfected women reported unintended pregnancies despite intending to avoid or delay pregnancy, highlighting the need for effective contraceptive methods that align with pregnancy intentions.

Early pregnancy factor (EPF) is a pregnancy protein, which is secreted into the maternal serum 12-16 hours after fertilization. It is thought to be an immunosuppressive molecule. EPF is detected in pregnant woman's serum by the rosette inhibition assay (RIA). In this study, EPF was purified from the pregnant woman's sera by using ion exchange chromatography and analyzed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The proteins which showed a positive result with the RIA, were found to be 35 kDa and 17 kDa molecular weights. The biological activities of these proteins were stable upon heat treatment at 56 degrees C for 30 min. Proteins isolated and purified in this study might be of great significance to the field of human reproduction with particular reference to pregnancy and recurrent abortion.

Autoantibodies as predictors of pregnancy complications.

PubMed

Carp, H J A; Meroni, P L; Shoenfeld, Y

2008-06-01

Certain autoantibodies which are found in autoimmune diseases including CTDs can impair fertility. Reproductive failure may present as pregnancy loss, either as miscarriage, intrauterine fetal death or stillbirth. There are also late obstetric complications such as intrauterine growth restriction, pre-eclampsia and pre-term birth. This review summarizes the possible influences of autoantibodies in reproductive failure, and particularly their predictive value (if available). The aPLs detectable by lupus anticoagulant, anti-cardiolipin or anti-beta2 glycoprotein I assays are associated with pregnancy loss and have a positive predictive value (PPV) of 75%. In spite of the general consensus on the management of pregnant aPL-positive women, few well-designed clinical trials have been reported and there is also insufficient data about the PPV of treatment. Anti-thyroid antibodies have been associated with pregnancy loss, and indeed have a PPV of 40%. However, no antibody is pathognomic for pregnancy loss. It may be more appropriate to assess a combination of antibodies rather than one antibody. However, a large meta-analysis of published trials is required in order to determine the prevalence of each particular autoantibody and different combinations of antibodies in different forms of reproductive failure.

To study the association between knowledge about levonorgestrel emergency contraception (LNG-EC) and the risk of ectopic pregnancy (EP) following LNG-EC failure. This study included 600 women who had visited the hospital with LNG-EC failure. Of these, 300 with EP and 300 with intrauterine pregnancy (IUP) were recruited to the EP group and IUP group respectively. The participants were interviewed face-to-face using a standardized questionnaire. Pearson's chi-square tests and t-test were used to compare the sociodemographic characteristics, reproductive and gynecological history, surgical history, previous contraceptive experience, and answers to 10 questions concerning the knowledge about LNG-EC. Those who gave incorrect answers to the question regarding the basic mechanism and specific method of levonorgestrel emergency contraceptive pills (LNG-ECPs) were at a higher risk of EP after LNG-EC failure. Women who did not strictly follow instructions or advice from healthcare professionals were more likely to subsequently experience EP (p < 10(-4) ). Women with LNG-EC failure reported friends/peers, TV, and Internet as the main sources of information. No difference was observed with regard to the sources of knowledge on LNG-EC (p = 0.07). The results illustrate the importance of strictly following the doctor's guidance or drug instructions when using LNG-ECPs. The media should be used to disseminate information about responsible EC, and pharmacy staff should receive regular educational training sessions in this regard. © 2016 The Authors.

Asymptomatic bacteriuria during pregnancy if left untreated, may lead to acute pyelonephritis, preterm labour, low birth weight foetus, etc. Adequate and early treatment reduces the incidence of these obstetric complications. The present study was done to determine presence of asymptomatic bacteriuria (ASB) and obstetric outcome following treatment in early versus late pregnancy. A prospective cohort study was conducted at a tertiary care teaching hospital of north India. Pregnant women till 20 wk (n=371) and between 32 to 34 wk gestation (n=274) having no urinary complaints were included. Their mid stream urine sample was sent for culture and sensitivity. Women having > 10 [5] colony forming units/ml of single organism were diagnosed positive for ASB and treated. They were followed till delivery for obstetric outcome. Relative risk with 95% confidence interval was used to describe association between ASB and outcome of interest. ASB was found in 17 per cent pregnant women till 20 wk and in 16 per cent between 32 to 34 wk gestation. Increased incidence of preeclamptic toxaemia (PET) [RR 3.79, 95% CI 1.80-7.97], preterm premature rupture of membrane (PPROM)[RR 3.63, 45% CI 1.63-8.07], preterm labour (PTL) [RR 3.27, 95% CI 1.38-7.72], intrauterine growth restriction (IUGR)[RR 3.79, 95% CI 1.80-79], low birth weight (LBW) [RR1.37, 95% CI 0.71-2.61] was seen in late detected women (32-34 wk) as compared to ASB negative women, whereas no significant difference was seen in early detected women (till 20 wk) as compared to ASB negative women. Early detection and treatment of ASB during pregnancy prevents complications like PET, IUGR, PTL, PPROM and LBW. Therefore, screening and treatment of ASB may be incorporated as routine antenatal care for safe motherhood and healthy newborn.

Preconception and early pregnancy air pollution exposures and risk of gestational diabetes mellitus

DOE Office of Scientific and Technical Information (OSTI.GOV)

Robledo, Candace A.; Mendola, Pauline, E-mail: pauline.mendola@mail.nih.gov; Yeung, Edwina

Background: Air pollution has been linked to gestational diabetes mellitus (GDM) but no studies have evaluated impact of preconception and early pregnancy air pollution exposures on GDM risk. Methods: Electronic medical records provided data on 219,952 singleton deliveries to mothers with (n=11,334) and without GDM (n=208,618). Average maternal exposures to particulate matter (PM) ≤ 2.5 μm (PM{sub 2.5}) and PM{sub 2.5} constituents, PM ≤ 10 μm (PM{sub 10}), nitrogen oxides (NO{sub x}), carbon monoxide, sulfur dioxide (SO{sub 2}) and ozone (O{sub 3}) were estimated for the 3-month preconception window, first trimester, and gestational weeks 1–24 based on modified Community Multiscalemore » Air Quality models for delivery hospital referral regions. Binary regression models with robust standard errors estimated relative risks (RR) for GDM per interquartile range (IQR) increase in pollutant concentrations adjusted for study site, maternal age and race/ethnicity. Results: Preconception maternal exposure to NO{sub X} (RR=1.09, 95% CI: 1.04, 1.13) and SO{sub 2} (RR=1.05, 1.01, 1.09) were associated with increased risk of subsequent GDM and risk estimates remained elevated for first trimester exposure. Preconception O{sub 3} was associated with lower risk of subsequent GDM (RR=0.93, 0.90, 0.96) but risks increased later in pregnancy. Conclusion: Maternal exposures to NO{sub x} and SO{sub 2} preconception and during the first few weeks of pregnancy were associated with increased GDM risk. O{sub 3} appeared to increase GDM risk in association with mid-pregnancy exposure but not in earlier time windows. These common exposures merit further investigation. - Highlights: • Air pollution may be related to gestational diabetes (GDM). • No prior studies have examined preconception exposure. • Maternal exposure to NO{sub x} and SO{sub 2} before conception increased subsequent GDM risk. • NO{sub x} and SO{sub 2} exposure in the first seven weeks of pregnancy also

Bacterial infections remain a major cause of morbidity and mortality in newborn infants. To determine the bacterial ecology and pathological status of the genital organs during the last trimester of pregnancy and the germs of the following early-onset neonatal sepsis, in order to evaluate the risk of materno-foetal infections and to find out a drug prophylaxis. Vaginal and endocervical samples, usually taken during the first trimester of pregnancy were delayed and taken during the last trimester of pregnancy. A macroscopic examination described the aspect of the vagina, the cervix uteri, leukorrhea and of possible inflammatory lesions or ulcerations. A microscopic examination searched for parasites, epithelial cells, clue cells and leukocytes. The appropriate bacteriological cultures were performed after reading the Gram stain and scoring the vaginal flora. The clinical and cytobacteriological aspects were used to identify the bacterial ecology and the pathological genital states. An exploration was carried out in every newborn suspected of infection. Genital samples were collected from 306 pregnant women. Among them, 118 were at 29-32 weeks of gestation, 104 at 33-36, and 84 at 37-40. The most frequent germs were C. albicans (33,5%), Enterbacteriaceae (20.3%) including E. coli (10.9%), S. aureus (15.4%), Gardnerella (13.6%), and Trichomonas (10.6%), in monomicrobian (79.2%) and polymicrobian carriage (20.8%). Lower genital tract pathological states such as vaginitis (29.4%), bacterial vaginosis (21.5%) or endocervicitis (10.4%), asymptomatic bacterial carriage (23.5%) and normal genital flora (15%) were identified. These pregnancies led to 334 live births with 27 cases of early-onset neonatal sepsis to which endocervicitis (25%) and vaginosis (19,7%) were most often linked. Genital samples at the last trimester of pregnancy could evaluate the risk of maternofoetal infections and allow to adapt a drug prophylaxis of Enterobacteriaceae, the most frequent germ of

Anxiety and depression symptoms in women and men from early pregnancy to 3-months postpartum: parity differences and effects.

This study aimed to investigate both anxiety and depression symptoms from early pregnancy to 3-months postpartum, comparing women and men and first and second-time parents. A sample of 260 Portuguese couples (N=520), first or second-time parents, recruited in an Obstetrics Out-patients Unit, filled in the State-Anxiety Inventory (STAI-S) and the Edinburgh Post-Natal Depression Scale (EPDS) at the 1st, 2nd and 3rd pregnancy trimesters, childbirth, and 3-months postpartum. A decrease in anxiety and depression symptoms from early pregnancy to 3-months postpartum was found in both women and men, as well as in first and second-time parents. Men presented less anxiety and depression symptoms than women, but the same pattern of symptoms over time. Second-time parents showed more anxiety and depression symptoms than first-time parents and a different pattern of symptoms over time: an increase in anxiety and depression symptoms from the 3rd trimester to childbirth was observed in first-time parents versus a decrease in second-time parents. The voluntary nature of the participation may have lead to a selection bias; women and men who agreed to participate could be those who presented fewer anxiety and depression symptoms. Moreover, the use of self-report symptom measures does not give us the level of possible disorder in participants. Anxiety and depression symptoms diminish from pregnancy to the postpartum period in all parents. Patterns of anxiety and depression symptoms from early pregnancy to 3-months postpartum are similar in women and men, but somewhat different in first and second-time parents. Second-time parents should also be considered while studying and intervening during pregnancy and the postpartum. Copyright © 2011 Elsevier B.V. All rights reserved.

Noninvasive, epitheliochorial placental attachment in the pig is regulated through endometrial production of protease inhibitors. The objective of the present study was to determine if the light-chain serine protease inhibitor of the inter-alpha-trypsin inhibitor family, bikunin, is produced by the porcine endometrium during the estrous cycle and early pregnancy. Western blot analysis revealed the presence of bikunin in uterine flushings of gilts collected during the luteal phase of the estrous cycle and early pregnancy (Days 12-18). However, bikunin unbound to the inter-alpha-trypsin heavy chains was detected only in endometrial explant culture medium obtained from estrus and pregnant (Days 12, 15, and 18) gilts. Endometrial bikunin gene expression was lowest on Day 10 of the estrous cycle and pregnancy, followed by a 30- to 77-fold increase on Day 15 of the estrous cycle and pregnancy. Bikunin gene expression decreased on Day 18 of the estrous cycle, whereas endometrial bikunin gene expression continued to increase in pregnant gilts. Bikunin mRNA was localized to the uterine glands between Days 15 and 18 of the estrous cycle and pregnancy. In addition to its role as a protease inhibitor, bikunin functions in stabilization of the extracellular matrix, which suggests that bikunin could be involved with facilitating placental attachment to the uterine epithelial surface in the pig.

The aim of this study was to compare the reproductive performance of dairy cows subjected to early (ER) or late (LR) resynchronization programs after nonpregnancy diagnoses based on either pregnancy-associated glycoproteins (PAG) ELISA or transrectal palpation, respectively. In addition, the accuracy of the PAG ELISA for early pregnancy diagnosis was assessed. Lactating Holstein cows were subjected to a Presynch-Ovsynch protocol with timed artificial insemination (AI) performed between 61 and 74 DIM. On the day of the first postpartum AI, 1,093 cows were blocked by parity and assigned randomly to treatments; however, because of attrition, 452 ER and 520 LR cows were considered for the statistical analyses. After the first postpartum AI, cows were observed daily for signs of estrus and inseminated on the same day of detected estrus. Cows from ER that were not reinseminated in estrus received the first GnRH injection of the Ovsynch protocol for resynchronization 2d before pregnancy diagnosis. On d 28 after the previous AI (d 27 to 34), pregnancy status was determined by PAG ELISA, and nonpregnant cows continued on the Ovsynch protocol for reinsemination. Pregnant cows had pregnancy status reconfirmed on d 46 after AI (d 35 to 52) by transrectal palpation, and those that lost the pregnancies were resynchronized. Cows assigned to LR had pregnancy diagnosed by transrectal palpation on d 46 after AI (d 35 to 52) and nonpregnant cows were resynchronized with the Ovsynch protocol. Blood was sampled on d 28 after AI (d 27 to 34) from cows in both treatments that had not been reinseminated on estrus and again on d 46 after AI (d 35 to 52) for assessment of PAG ELISA to determine the accuracy of the test. Cows were subjected to treatments for 72d after the first insemination. Pregnancy per AI (P/AI) at first postpartum timed AI did not differ between treatments and averaged 28.9%. The proportion of nonpregnant cows that were resynchronized and received timed AI was greater

Chronic exposure to bisphenol a impairs progesterone receptor-mediated signaling in the uterus during early pregnancy

Environmental and occupational exposure to endocrine disrupting chemicals (EDCs) is a major threat to female reproductive health. Bisphenol A (BPA), an environmental toxicant that is commonly found in polycarbonate plastics and epoxy resins, has received much attention due to its estrogenic activity and high risk of chronic exposure in human. Whereas BPA has been linked to infertility and recurrent miscarriage in women, the impact of its exposure on uterine function during early pregnancy remains unclear. In a recent publication in Endocrinology, we demonstrated that prolonged exposure to an environmental relevant dose of BPA disrupts progesterone receptor-regulated uterine functions, thus affecting uterine receptivity for embryo implantation and decidua morphogenesis, two critical events for establishment and maintenance of early pregnancy. In particular we reported a marked impairment of progesterone receptor (PGR) expression and its downstream effector HAND2 in the uterine stromal cells in response to chronic BPA exposure. In an earlier study we have shown that HAND2 controls embryo implantation by repressing fibroblast growth factor (FGF) expression and the MAP kinase signaling pathway, thus inhibiting epithelial proliferation. Interestingly we observed that downregulation of PGR and HAND2 expression in uterine stroma upon BPA exposure was associated with an enhanced activation of FGFR and MAPK signaling, aberrant proliferation, and lack of uterine receptivity in the epithelium. In addition, the proliferation and differentiation of endometrial stromal cells to decidual cells, an event critical for the maintenance of early pregnancy, was severely compromised in response to BPA. This research highlight will provide an overview of our findings and discuss the potential mechanisms by which chronic BPA impairs PGR-HAND2 pathway and adversely affects implantation and the establishment of pregnancy.

Many countries have maternity protection laws for women who need job modification or medical leave during pregnancy. This approach will prevent birth defects only if maternal job changes can be made before the critical period of organogenesis, which begins at three weeks' gestation. The authors studied the gestational ages at which pregnant women working with chemicals, radiation, and noise presented for occupational safety and health consultations. The work setting promoted early presentation because the consultation was free, convenient, mandatory, and would not result in job loss. Among the 213 pregnant women evaluated between 1996 and 2000, most (89.5%) had their occupational safety evaluations in the first trimester. Although this sounds ideal, the mean gestational age at presentation was 7.5 weeks, and only 3.3% of occupational health evaluations were initiated by three weeks' gestation. Environmental and biological monitoring showed that none of the women was exposed over occupational limits. These data suggest that a workplace free from reproductive hazards needs to be provided before conception.

Cesarean scar pregnancy (CSP) is a serious complication of pregnancy, which consists of implantation of the gestational sac in the hysterotomy scar. This condition is increasing in frequency and often poses a diagnostic challenge. Its diagnosis is dependent on visual assessment of the uterus on the longitudinal sagittal ultrasound plane. Misdiagnosing a low intrauterine chorionic sac as a CSP, or a true scar pregnancy as an intrauterine pregnancy (IUP), may lead to adverse outcomes including hysterectomy. The objective of the study is to describe a sonographic method for the differential diagnosis of CSP vs IUP in early gestation. The current study tests the hypothesis that on a first-trimester ultrasound performed between 5-10 weeks of gestation, the relative location of the center of gestational sac to the midpoint of the uterus along a longitudinal line between the external cervical os and the fundus can be used for early detection of CSPs. This is a retrospective review of electronically archived ultrasound images of IUP and CSP between 5-10 weeks of gestation. A total of 242 ultrasound images were analyzed: 185 cases of normal IUPs (including 128 in anteverted uteri, 31 in retroverted uteri, and 26 IUPs with history of cesarean delivery) and 57 cases of CSPs diagnosed from 2004 through 2015 in a single institution. The following measurements were made for each case: distance from the external cervical os to the uterine fundus, the midpoint axis of the uterus, the distance from the external cervical os to the center of gestational sacs, and the distance from the external cervical os to the most distant edge of the gestational sacs from the cervix. The location of the center of the gestational sac relative to the midpoint axis of the uterus between 5-10 weeks of gestation differentiated between IUP and CSP (mean 17.8 vs -10.6 mm, respectively, P = .0001), indicating that most CSPs are located proximally to the midpoint axis of the uterus whereas most normal

Of more developed nations, the US is unique in its problem with high rates of teen pregnancy. At the heart of our failure to check teen pregnancy may lie the country's poor sexual climate, a lack of government commitment, poor health system performance, local barriers to the provision of quality sex education, and/or lack of access to contraception. Potential solutions to reduce teen pregnancy are equally wide-ranging. Programs may aim to provide better and more health and sex education, improve decision making skills, improve access to contraception and abortion, improve life opportunities as alternatives to pregnancies, restructure welfare, and/or encourage youths to refrain from premarital sex. This essay presents and discusses major prevention efforts which seem to have the highest probability of reducing pregnancy rates, and especially childbearing rates among young, unmarried teens. Literature on program successes, agency reports, and program observations are reviewed, and include programs of sex education and skills enhancement, those helping sexually active youths become better contraceptors, and those which offer life option alternatives. In the area of improving access to contraception, school-based clinics, condom distribution, and other male-oriented programs are covered. Major social structural change is, however, called for with a view to promoting equity in education, housing, and jobs. Short of such change, interventions may target school-based populations, as well as community centers to reach dropouts. Early intervention and collaboration to bolster health, social, and recreational services for children and adolescents is urged.

Mouse and human pregnancy-specific glycoproteins (PSG) are known to exert immunomodulatory functions during pregnancy by inducing maternal leukocytes to secrete anti-inflammatory cytokines that promote a tolerogenic decidual microenvironment. Many such anti-inflammatory mediators also function as proangiogenic factors, which, along with the reported association of murine PSG with the uterine vasculature, suggest that PSG may contribute to the vascular adaptations necessary for successful implantation and placental development. We observed that PSG22 is strongly expressed around the embryonic crypt on Gestation Day 5.5, indicating that trophoblast giant cells are the main source of PSG22 during the early stages of pregnancy. PSG22 treatment up-regulated the secretion of transforming growth factor beta 1 and vascular endothelial growth factor A (VEGFA) in murine macrophages, uterine dendritic cells, and natural killer cells. A possible role of PSGs in uteroplacental angiogenesis is further supported by the finding that incubation of endothelial cells with PSG22 resulted in the formation of tubes in the presence and absence of VEGFA. We determined that PSG22, like human PSG1 and murine PSG17 and PSG23, binds to the heparan sulfate chains in syndecans. Therefore, our findings indicate that despite the independent evolution and expansion of human and rodent PSG, members in both families have conserved functions that include their ability to induce anti-inflammatory cytokines and proangiogenic factors as well as to induce the formation of capillary structures by endothelial cells. In summary, our results indicate that PSG22, the most abundant PSG expressed during mouse early pregnancy, is likely a major contributor to the establishment of a successful pregnancy.

Background: Pregnancy luteoma is a rare non neoplastic condition of the ovary. It is usually asymptomatic and found incidentally during imaging in pregnancy or during cesarean section. Pregnancy luteoma can also occur after ectopic pregnancy. Case Presentation: A 30 year old female presented to G.B. Pant Hospital, Andaman and Nicobar Islands institute of Medical Sciences, Port Blair in October 2015 with abdominal pain. After initial investigations, exploratory laporotomy was done for ruptured ectopic pregnancy. Enlarged ovary was removed along with the ruptured portion of fallopian tube. Histopathological examination revealed solid aggregates of large cells with abundant eosinophilic cytoplasm; diagnosis of pregnancy luteoma was given. Conclusion: It must be considered in the differential diagnosis of ovarian masses in pregnant females that early diagnosis of this entity may avoid unnecessary radical surgery. PMID:29062798

The purpose of this study was to determine whether exposure to stressful life events was associated with changes in levels of circulating cortisol during pregnancy in a population of 603 pregnant women. The participating pregnant women filled out a questionnaire and collected a morning and evening sample of saliva in early pregnancy (median 14th gestational week) and in late pregnancy (median and 30th gestational week). They were asked to report the number of life events experienced during first and second trimester, respectively, and were asked to rate the intensity of the experienced events. Complications related to the pregnancy such as vaginal bleeding and suspected growth retardation were registered and the women were asked about concerns about their pregnancy. The salivary samples were analyzed for cortisol and the levels were higher in late than in early pregnancy. In late pregnancy women exposed to more than one life event or were concerned about pregnancy complications during second trimester had a higher evening cortisol level, whereas morning values were unaffected. After adjustment for smoking women who experienced more than one very stressful life event had 27% higher evening cortisol concentrations (95% confidence intervals: 1-59%). Women with worries about pregnancy complications had 27% (95% confidence intervals: 2-57%) higher levels. In early pregnancy women reporting stressful life events did not have higher evening cortisol levels, but tended to have a blunted morning HPA response. In conclusion, we found differences in the associations between chronic stress in early and late pregnancy and cortisol levels indicating that the response to chronic stress is dependent on the stage of the pregnancy.

A 21-year-old woman in the 16th week of pregnancy was admitted due to acute presentation of severe exertional dyspnea. She had undergone mitral valve replacement (MVR) with bioprosthetic valve for infective endocarditis 2 years ago. She developed congestive heart failure from mitral bioprosthetic valve stenosis due to early structural valve deterioration. She also had severe pulmonary hypertension and underwent a redo MVR using a mechanical valve prosthesis with good maternal outcome but fetal demise. This report brings up the debate about what type of valve should be used in women in reproductive age, and discusses the management of severe mitral stenosis and stenosis of a bioprosthetic valve during pregnancy. Surgical options can almost always be delayed until fetal maturity is achieved and a simultaneous cesarean section can be performed. However, under certain circumstances when the maternal welfare is in jeopardy the surgical intervention is mandatory even before the fetus reaches viability.

We sought to explore the clinical variables associated with the loss of rubella immunity during pregnancy and to determine if these changes are linked to obstetrical complications. This is a case-control study in which women were identified whose rubella antibody titers were equivocal or non-immune and compared to those who had retained immunity. Two hundred and eighty-five cases were identified and compared to the same number of controls using Student's t test, Mann-Whitney U-test or Fisher's exact test. Univariate and multivariate logistic regressions were employed. Subjects with diminished immunity were more likely to have public insurance and higher gravidity with a trend toward increased tobacco use. Diminished rubella immunity was not associated with adverse obstetrical outcomes, including preterm birth and pre-eclampsia and is likely not a risk factor for these pregnancy outcomes. While no adverse pregnancy outcomes were associated with a loss of rubella immunity, women with greater number of pregnancies appear to lose their immunity to rubella. This relationship needs to be explored further and if proven, revaccination prior to pregnancy may need to be addressed.

Teenage pregnancy.

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.

Maternal glucose and lipid levels are associated with neonatal anthropometry of the offspring, also independently of maternal body mass index (BMI). Gestational weight gain, however, is often not accounted for. The objective was to explore whether the effects of maternal glucose and lipid levels on offspring's birth weight and subcutaneous fat were independent of early pregnancy BMI and mid-gestational weight gain. In a population-based, multi-ethnic, prospective cohort of 699 women and their offspring, maternal anthropometrics were collected in gestational week 15 and 28. Maternal fasting plasma lipids, fasting and 2-hour glucose post 75 g glucose load, were collected in gestational week 28. Maternal risk factors were standardized using z-scores. Outcomes were neonatal birth weight and sum of skinfolds in four different regions. Mean (standard deviation) birth weight was 3491 ± 498 g and mean sum of skinfolds was 18.2 ± 3.9 mm. Maternal fasting glucose and HDL-cholesterol were predictors of birth weight, and fasting and 2-hour glucose were predictors of neonatal sum of skinfolds, independently of weight gain as well as early pregnancy BMI, gestational week at inclusion, maternal age, parity, smoking status, ethnic origin, gestational age and offspring's sex. However, weight gain was the strongest independent predictor of both birth weight and neonatal sum of skinfolds, with a 0.21 kg/week increased weight gain giving a 110.7 (95% confidence interval 76.6-144.9) g heavier neonate, and with 0.72 (0.38-1.06) mm larger sum of skinfolds. The effect size of mother's early pregnancy BMI on birth weight was higher in non-Europeans than in Europeans. Maternal fasting glucose and HDL-cholesterol were predictors of offspring's birth weight, and fasting and 2-hour glucose were predictors of neonatal sum of skinfolds, independently of weight gain. Mid-gestational weight gain was a stronger predictor of both birth weight and neonatal sum of skinfolds than early

Abnormal maternal thyroid function in pregnancy may impair fetal brain development, but more evidence is needed to refine and corroborate the hypothesis. To estimate the association between maternal thyroid function in early pregnancy and neuropsychological performance of the child at 5 years of age. Follow-up study. A cohort of 1153 women and their children sampled from the Danish National Birth Cohort. Maternal thyroid-stimulating hormone (TSH) and free thyroxine (fT4) were measured in stored biobank sera from early pregnancy. Child neuropsychological test results (Wechsler Intelligence Scale/Test of Everyday Attention), test of motor function (Movement Assessment Battery), and results of parent and teacher reports (Behavior Rating Inventory of Executive Function/Strengths and Difficulties Questionnaire). Altogether 145 children (12.6%) were born to mothers with abnormal thyroid function in the early pregnancy. High maternal TSH and low fT4 were associated with lower child verbal intelligence quotient (adjusted mean difference TSH ≥ 10 mIU/L vs 0.1 to 2.49 mIU/L, -8.9 [95% confidence interval (CI), -15 to -2.4]; fT4 < 10 pmol/l vs 12.0 to 18.99 pmol/l, -13 [95% CI, -19 to -7.3]). Abnormal maternal thyroid function was also associated with adverse motor function and teacher-reported problems of executive function and behavior, and these associations were dominated by exposure to maternal hypothyroxinemia. Maternal thyroid hormone abnormalities were associated with adverse neuropsychological function of the child at 5 years of age. For intelligence, marked hypothyroidism was important, whereas for motor function and executive and behavior problems, maternal hypothyroxinemia was predominant. Copyright © 2017 Endocrine Society

Effect of women's nutrition before and during early pregnancy on maternal and infant outcomes: a systematic review.

Current understanding of biologic processes indicates that women's nutritional status before and during early pregnancy may play an important role in determining early developmental processes and ensuring successful pregnancy outcomes. We conducted a systematic review of the evidence for the impact of maternal nutrition before and during early pregnancy (<12 weeks gestation) on maternal, neonatal and child health outcomes and included 45 articles (nine intervention trials and 32 observational studies) that were identified through PubMed and EMBASE database searches and examining review articles. Intervention trials and observational studies show that periconceptional (<12 weeks gestation) folic acid supplementation significantly reduced the risk of neural tube defects. Observational studies suggest that preconceptional and periconceptional intake of vitamin and mineral supplements is associated with a reduced risk of delivering offspring who are low birthweight and/or small-for-gestational age (SGA) and preterm deliveries (PTD). Some studies report that indicators of maternal prepregnancy size, low stature, underweight and overweight are associated with increased risks of PTD and SGA. The available data indicate the importance of women's nutrition prior to and during the first trimester of pregnancy, but there is a need for well-designed prospective studies and controlled trials in developing country settings that examine relationships with low birthweight, SGA, PTD, stillbirth and maternal and neonatal mortality. The knowledge gaps that need to be addressed include the evaluation of periconceptional interventions such as food supplements, multivitamin-mineral supplements and/or specific micronutrients (iron, zinc, iodine, vitamin B-6 and B-12) as well as the relationship between measures of prepregnancy body size and composition and maternal, neonatal and child health outcomes. © 2012 Blackwell Publishing Ltd.

Chronic Exposure to Bisphenol A Affects Uterine Function During Early Pregnancy in Mice

Environmental and occupational exposure to bisphenol A (BPA), a chemical widely used in polycarbonate plastics and epoxy resins, has received much attention in female reproductive health due to its widespread toxic effects. Although BPA has been linked to infertility and recurrent miscarriage in women, the impact of its exposure on uterine function during early pregnancy remains unclear. In this study, we addressed the effect of prolonged exposure to an environmental relevant dose of BPA on embryo implantation and establishment of pregnancy. Our studies revealed that treatment of mice with BPA led to improper endometrial epithelial and stromal functions thus affecting embryo implantation and establishment of pregnancy. Upon further analyses, we found that the expression of progesterone receptor (PGR) and its downstream target gene, HAND2 (heart and neural crest derivatives expressed 2), was markedly suppressed in BPA-exposed uterine tissues. Previous studies have shown that HAND2 controls embryo implantation by repressing fibroblast growth factor and the MAPK signaling pathways and inhibiting epithelial proliferation. Interestingly, we observed that down-regulation of PGR and HAND2 expression in uterine stroma upon BPA exposure was associated with enhanced activation of fibroblast growth factor and MAPK signaling in the epithelium, thus contributing to aberrant proliferation and lack of uterine receptivity. Further, the differentiation of endometrial stromal cells to decidual cells, an event critical for the establishment and maintenance of pregnancy, was severely compromised in response to BPA. In summary, our studies revealed that chronic exposure to BPA impairs PGR-HAND2 pathway and adversely affects implantation and the establishment of pregnancy. PMID:27022677

Maternal pre-pregnancy overweight and obese status has been associated with a number of pregnancy complications and adverse offspring outcomes. Mechanisms for observed associations, however, are largely unknown. We investigated associations of pre-pregnancy body mass index with early-mid pregnancy epigenetic biomarkers, circulating microRNAs. Peripheral blood was collected from participants (16-27 weeks gestation) of two multi-racial pregnancy cohorts, the Omega Study and the Pregnancy Outcomes and Community Health Study. Plasma miRNA expression was characterised using epigenome-wide (319 miRNAs) profiling among 20 pregnant women in each cohort. Cohort-specific linear regression models that included the predictor (pre-pregnancy body mass index), the outcome (microRNA expression), and adjustment factors (maternal age, gestational age at blood collection, and race) were fit. Expression of 27 miRNAs was positively associated with pre-pregnancy body mass index in both cohorts (p-values <0.05). A number of these differentially expressed miRNAs have previously been associated with adipogenesis (e.g. let-7d*, miR-103-2*, -130b, -146b-5-p, -29c, and -26b). Identified miRNAs as well as their experimentally validated targets participate in pathways that involve organismal injury, reproductive system disease, connective tissue disorders, cancer, cellular development, growth and proliferation. Pre-pregnancy body mass index is associated with circulating miRNAs in early-mid pregnancy. Published by Elsevier Ltd.

Uterine artery pseudoaneurysm (UAP) normally presents genital bleeding in the puerperal period, and severe hydronephrosis rarely presents during pregnancy. We report a rare case of severe ureteral obstruction accompanied by uterine artery pseudoaneurysm in the early second trimester of pregnancy, which was successfully treated by surgical intervention. A 42-year-old nulligravid woman who had undergone myomectomy 3 years earlier was referred to our hospital for acute left abdominal pain at the 17th week of gestation. Ultrasonography showed severe left hydronephrosis and a 6-cm mass in the parauterine space. Color Doppler ultrasonography revealed a spinning turbulent flow pattern inside the mass lesion. Contrast-enhanced computed tomography revealed the left uterine artery feeding blood flow to the mass and left ureteral obstruction by the mass. These results indicated left hydronephrosis secondary to left uterine artery pseudoaneurysm. To resolve the problem, laparotomy was performed. As uterine artery isolation was impossible, ligation of the left internal iliac artery and releasing of the ureteral obstruction were carried out. The hydronephrosis and abdominal pain promptly resolved after the surgery. Thereafter, fetal development proceeded normally in the remaining months of the pregnancy. A healthy baby was delivered through cesarean section at 36 weeks gestational age. At the cesarean section, the left lower uterine segment where the UAP had been present was not visible because of the firm adhesion in around it. Uterine artery pseudoaneurysm can cause hydronephrosis in the early second trimester of pregnancy. Ligation of the unilateral internal iliac artery is a safe and effective intervention to block the blood flow to the uterine artery pseudoaneurysm during pregnancy, when uterine artery ligation seems not possible. In the pregnancy after previous surgical procedures to the uterus, uterine artery pseudoaneurysm should be considered in the differential

The aim of this study was to explore changes in health-related quality of life, anxiety and depression symptoms during pregnancy in women with pregestational diabetes. An observational cohort study including 137 pregnant women with pregestational diabetes (110 with type 1 and 27 with type 2). To evaluate changes from early to late pregnancy, the internationally validated questionnaires 36-Item Short-Form Health Survey (SF-36) and Hospital Anxiety and Depression Scale (HADS) were completed at 8 and 33 gestational weeks. From early to late pregnancy, the SF-36 scales Physical Function, Role Physical, Bodily Pain and Physical Component Summary worsened (p < 0.0001 for all scales). Physical Component Summary score deteriorated from mean 52.3 (SD 6.5) to 40.0 (9.7) (p < 0.0001) and the deterioration was negatively associated with gestational weight gain in multiple linear regression (β = -0.34/kg, p = 0.03). The SF-36 scale Mental Health improved (p = 0.0009) and the Mental Component Summary score increased moderately from 47.6 (10.6) to 53.5 (8.6) (p < 0.0001). Greater improvement in Mental Component Summary score was seen with lower HbA1c in late pregnancy. The HADS anxiety score improved slightly from 5.0 (3.3) to 4.5 (3.4) (p = 0.04) whereas the HADS depression score remained unchanged. The prevalence of women with HADS anxiety or depression score ≥8 did not change. Physical quality of life deteriorated whereas mental quality of life improved slightly during pregnancy in women with pregestational diabetes. A minor reduction in anxiety and stable depression symptoms was observed. The results on mental health are reassuring, considering the great demands that pregnancy places on women with pregestational diabetes. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

Endocrine basis for recurrent pregnancy loss.

Common endocrinopathies are a frequent contributor to spontaneous and recurrent miscarriage. Although the diagnostic criteria for luteal phase defect (LPD) is still controversial, treatment of patients with both recurrent pregnancy loss and LPD using progestogen in early pregnancy seems beneficial. For patients who are hypothyroid, thyroid hormone replacement therapy along with careful monitoring in the preconceptual and early pregnancy period is associated with improved outcome. Women with polycystic ovary syndrome (PCOS) have an increased risk of pregnancy loss. Management of PCOS with normalization of weight or metformin seems to reduce the risk of pregnancy loss.

Objectives. To investigate the association between the maternal alcohol consumption during pregnancy and early age leukemia (EAL) in offspring. Methods. Datasets were analyzed from a case-control study carried out in Brazil during 1999-2007. Data were obtained by maternal interviews using a standardized questionnaire. The present study included 675 children (193 acute lymphoid leukemia (ALL), 59 acute myeloid leukemia (AML), and 423 controls). Unconditional logistic regression was performed, and adjusted odds ratios (adj. OR) on the association between alcohol consumption and EAL were ascertained. Results. Alcohol consumption was reported by 43% of ALL and 39% of AML case mothers and 35.5% of controls'. Beer consumption before and during pregnancy was associated with ALL in crude analysis (OR = 1.54, 95% CI, 1.08-2.19), although in adjusted analysis no statistical significance was found. For weekly intake of ≤1 glass (adj. OR = 1.30, 95% CI, 0.71-2.36) and ≥1 glass/week (adj. OR = 1.47, 95% CI, 0.88-2.46) a potential dose-response was observed (P trend < 0.03). Conclusion. This study failed to support the hypothesis of an increased risk of EAL associated with maternal alcohol intake during pregnancy, neither with the interaction with tobacco nor with alcohol consumption.

Continuation of metformin reduces early pregnancy loss in obese Pakistani women with polycystic ovarian syndrome.

Polycystic ovarian syndrome (PCOS) is the most common cause of anovulatory infertility worldwide. In addition to a poor conception rate, pregnancy loss rates are significantly higher (30-50%) during the first trimester in women with PCOS. Insulin resistance (IR) in this syndrome is not only implicated toward early pregnancy loss (EPL) but also pathognomic for various obstetrical complications during pregnancy. We evaluated the role of Metformin in the reduction of EPL in women with PCOS who conceived spontaneously or after induction ovulation with or without Metformin. The primary objective was to evaluate the effectiveness of Metformin in the reduction of EPL in women with PCOS. Secondary outcomes like gestational diabetes, pregnancy-induced hypertension and intrauterine growth restriction were also analyzed at the end of the study. This case-control study was conducted from March 2005 to March 2008 in the infertility and antenatal clinics of the Department of Obstetrics and Gynecology of Aga Khan University Hospital, Karachi, Pakistan. A total of 197 infertile women with PCOS were included. 'Cases' were women with PCOS who conceived while taking Metformin and it whom it was continued throughout pregnancy. 'Controls' were women in whom Metformin was either stopped in first trimester after confirmation of pregnancy (by serum betaHCG or by ultrasound) or they conceived spontaneously without the use of Metformin. All 197 women in this study had a confirmed diagnosis of PCOS (Rotterdam criteria). These women were followed till the final outcome of pregnancy was achieved. Both groups were compared for risk of EPL. It was found that continuation of Metformin during pregnancy reduces EPL, i.e. 8.8 vs. 29.4% in cases and controls, respectively (p < 0.001). In the subset of women with a prior history of miscarriage, the pregnancy loss rate was 12.5% in the Metformin versus 49.4% in control group (p = 0.002). Metformin continuation during pregnancy significantly reduces EPL

Proving incest from tissue obtained by abortion early in pregnancy can be a challenge. Problems include the small quantity of embryonic tissue in the products of conception, and the mixing of DNA from mother and embryo. In many cases, this amorphous material cannot be grossly segregated into maternal and fetal components. Thus, morphological discrimination requires microscopy to select relevant tissue particles from which DNA can be typed. This combination of methods is reliable and efficient. In this article, we present two cases of incest discovered by examination of products of conception. Copyright © 2010 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Little is known regarding the transit-time flow measurement (TTFM) variables in grafts anastomosed to chronically totally occluded vessels (CTOs). We aimed to establish the TTFM cut-off values for detecting graft failure in bypass grafts anastomosed to chronically totally occluded arteries and clarify the relationship between early graft failure and the grade of collateral circulation/regional wall motion of the CTO territory. Among 491 patients who underwent isolated coronary artery bypass grafting (CABG) from 2009 to 2015, 196 cases with CTOs underwent postoperative coronary angiography within 1 month after CABG. Two hundred and forty-one CTOs in all patients were examined. Thirty-two CTOs (13%) were not bypassed and 214 conduits were anastomosed to CTOs and underwent intraoperative TTFM. Arterial conduits and saphenous vein grafts (SVGs) were used in 102 and 112 cases, respectively. Among the arterial conduit procedures that were performed, 78 involved the left internal thoracic artery (LITA), 10 involved the right internal thoracic artery (RITA) and 14 involved the right gastroepiploic artery (rGEA). Any graft showing Fitzgibbon type B or O lesions on angiography was considered to be a failing graft. The insufficiency rates for LITA, RITA, rGEA and SVG procedures were 5.1, 10, 14.3 and 7.1%, respectively. The TTFM variables recorded in failing grafts had a significantly lower mean flow (Qmean) and higher pulsatility index (PI) compared with patent grafts. Furthermore, akinetic or dyskinetic wall motion in the territory of bypassed CTOs was observed at a significantly higher rate in failing grafts. A multivariable regression analysis and receiver operating characteristic analysis revealed good predictors of early graft failure as follows: a Qmean value of < 11.5 ml/min for arterial conduits, a PI value of >5.85 and akinetic/dyskinetic wall motion in the CTO territory for SVGs. The Rentrop collateral grade was not associated with early graft failure. The Qmean

What are the consequences of inhibiting mTOR, the mechanistic target of rapamycin (mTOR), and the peroxisome proliferator activated receptor gamma (PPARγ) and PPARδ pathways in the early post-implantation period on decidual function, embryo viability and feto-placental growth in the rat? mTOR inhibition from Days 7 to 9 of pregnancy in rats caused decidual PPARγ and PPARδ upregulation on Day 9 of pregnancy and resulted in embryo resorption by Day 14 of pregnancy. PPARγ and PPARδ inhibition differentially affected decidual mTOR signaling and levels of target proteins relevant to lipid histotrophic nutrition and led to reduced feto-placental weights on Day 14 of pregnancy. Although mTOR, PPARγ and PPARδ are nutrient sensors important during implantation, the role of these signaling pathways in decidual function and how they interact in the early post-implantation period are unknown. Perilipin 2 (PLIN2) and fatty acid binding protein 4 (FABP4), two adipogenic proteins involved in lipid histotrophic nutrition, are targets of mTOR and PPAR signaling pathways in a variety of tissues. Rapamycin (mTOR inhibitor, 0.75 mg/kg, sc), T0070907 (PPARγ inhibitor, 0.001 mg/kg, sc), GSK0660 (PPARδ inhibitor, 0.1 mg/kg, sc) or vehicle was injected daily to pregnant rats from Days 7 to 9 of pregnancy and the studies were performed on Day 9 of pregnancy (n = 7 per group) or Day 14 of pregnancy (n = 7 per group). On Day 9 of pregnancy, rat decidua were collected and prepared for western blot and immunohistochemical studies. On Day 14 of pregnancy, the resorption rate, number of viable fetuses, crown-rump length and placental and decidual weights were determined. Inhibition of mTOR in the early post-implantation period led to a reduction in FABP4 protein levels, an increase in PLIN2 levels and an upregulation of PPARγ and PPARδ in 9-day-pregnant rat decidua. Most embryos were viable on Day 9 of pregnancy but had resorbed by Day 14 of pregnancy. This denotes a key function of

Despite the well-documented benefits of a physically active lifestyle, over 25% of American adults report that they never engage in regular recreational physical activity. Little is known about the determinants of physical activity among pregnant women. We investigated the predictors of physical activity in 386 normotensive pregnant women. Participants provided information about the type, frequency and duration of each physical activity performed during the first 20 weeks of pregnancy. We calculated odd ratios (OR) for active compared with inactive women using logistic regression models. Approximately 61% of women reported participating in some regular physical activity during pregnancy. Walking, swimming, gardening and jogging were the most common activities. Physical activity as an adolescent (OR 4.0) and during the year before pregnancy (OR 48.9) were the strongest predictors of physical activity in pregnancy. Active women who continued to exercise during pregnancy decreased the average intensity of their exercise and the weekly duration of exercise compared with the year before pregnancy. Nulliparas were twice as likely to engage in physical activity as compared with multiparas. Education and income were positively related with physical activity. Non-White women were 40-60% less likely to engage in physical activity as compared with White women. Smokers were also less likely to engage in physical activity. High protein intake was positively associated with physical activity, while the opposite was true for high carbohydrate intake. The identification of determinants of physical activity in pregnancy has important implications for developing strategies aimed at promoting a physically active lifestyle among young women.

The aims of this study were to examine the anxiety trajectories of women from pregnancy to 2 years postpartum and to assess the influence of their early life experiences and the temperament of the child on these trajectories. We evaluated state anxiety (State-Trait Anxiety Inventory) at pregnancy and 3, 6, 12, 18, and 24 months postpartum and determined its course as a function of self-reported early adverse experiences (Childhood Trauma Questionnaire) and the temperament of the child at 18 months (Early Child Behavior Questionnaire). Based on growth curve modeling, we found that anxiety followed a general U-shape pattern from gestation to 2 years postpartum, which was modified by early life experience of women. Greater early adversity was associated with higher gestational anxiety, followed by a marked decrease once the baby was born, and subsequent increase during the later postpartum period. The temperament of the child also modulated anxiety trajectories. Thus, mothers of children high in negative affectivity and who also experienced greater early adversity had elevated and flat anxiety trajectories, while child extraversion was associated with increasing anxiety courses approaching 2 years postpartum. These results show that maternal anxiety dynamically changes through the postpartum period with a course that is affected by previous and current experiences.

Potential factors affecting retention of pregnancy during weeks 5-9 of gestation were studied in dairy cows and heifers (N = 211) on two farms. Cows were examined by ultrasonography for presence of a viable embryo, and sizes of the corpus luteum (CL) and of follicles > or = 5mm were recorded. Blood samples were taken at each examination and assayed for progesterone and estradiol. Overall pregnancy loss was 11.4%. Cows with two CL did not have greater concentrations of progesterone than cows with one CL and they retained fewer pregnancies (P < 0.01; 73% versus 91%). Pregnancy retention was associated positively with concentrations of progesterone and estradiol during week 5 (P < 0.05). Embryos that were lost apparently died before CL regression. Retention of pregnancy declined in cows with high body condition and as age of the cow increased. Pregnancy retention was lower in cows bred to one of four frequently-used service sires (P < 0.05). Days postpartum, milk production, parity, service number, inseminator, synchronization of estrus, diameter of follicles and size of CL did not affect pregnancy retention. In conclusion, retention of pregnancy during placentation varied with concentrations of progesterone and estradiol, age of cow, body condition and service sire.

Maternal hCG concentrations in early IVF pregnancies: associations with number of cells in the Day 2 embryo and oocytes retrieved.

Do number of cells in the transferred cleavage stage embryo and number of oocytes retrieved for IVF influence maternal hCG concentrations in early pregnancies? Compared with transfer of a 2-cell embryo, transfer of a 4-cell embryo results in higher hCG concentrations on Day 12 after transfer, and more than 20 oocytes retrieved were associated with low hCG concentrations. Maternal hCG concentration in very early pregnancy varies considerably among women, but is likely to be an indicator of time since implantation of the embryo into the endometrium, in addition to number and function of trophoblast cells. We followed 1047 pregnancies after IVF/ICSI from oocyte retrieval until Day 12 after embryo transfer. Women were recruited in Norway during the years 2005-2013. Successful pregnancies after transfer of one single embryo that had been cultured for 2 days were included. Maternal hCG was quantified on Day 12 after embryo transfer by chemiluminescence immunoassay, which measures intact hCG and the free β-hCG chain. Information on a successful pregnancy, defined as birth after >16 weeks, was obtained by linkage to the Medical Birth Registry of Norway. Transfer of a 4-cell embryo resulted in higher maternal hCG concentrations compared with transfer of a 2-cell embryo (134.8 versus 87.8 IU/l, P < 0.05). A high number of oocytes retrieved (>20) was associated with low hCG concentrations (P < 0.05). The factors studied explain a limited part of the total variation of hCG concentrations in early pregnancy. Although embryo transfer was performed at the same time after fertilization, we do not know the exact time of implantation. A further limitation to our study is that the number of pregnancies after transfer of a 2-cell embryo was small (27 cases). Number of cells in the transferred embryo and number of oocytes retrieved may influence the conditions and timing for embryo implantation in different ways and thereby influence maternal hCG concentrations. Such knowledge may be
