Our statistical methods controlled for temporal patterns in spontaneous abortion (e.g., seasonality, trend) and changes in the population of pregnancies at risk of loss. Unexpected increases in the unemployment rate preceded...... in elective abortions and in the cohort composition of high-risk pregnancies did not account for results. It appears that in Denmark, ambient stressors as common as increasing unemployment may precede a population-level increase in spontaneous abortion....
Full Text Available Context: Bacterial vaginosis (BV is related to the increased risk of miscarriage, preterm labor, and postpartum endometritis. Aims: The aim of this study was to evaluate the association between BV and the history of spontaneous abortion and recurrent pregnancy losses. We also examined periods of gestation, including the first and second trimester miscarriages. Materials and Methods: The study population consisted of 200 fertile women. Sixty one (30.5% of 200 women had the history of a spontaneous abortion in the last six months (N = 30 and at least three recurrent pregnancy losses (N = 31. BV was diagnosed either by using Papanicolaou staining, Gram staining, or by culturing with BV-associated bacteria, Gardnerella vaginalis. Results: The presence of BV was statistically associated with the history of a spontaneous abortion in the last 6 months (P 0.05. These women were also evaluated in view of periods of gestation. Forty-seven (77% of 61 women had first trimester miscarriage (≤12 weeks and 14 (23% of 61 women had second trimester miscarriage (>12 weeks. There was a statistically significant relationship between BV and second trimester miscarriage (P 0.05. Conclusion: BV may contribute to spontaneous abortion and second trimester miscarriage.

Full Text Available Pregnancy loss is an important aspect of equine practice due to the economic and emotional loss that it engenders. Pregnancy loss is often divided in two categories: early pregnancy loss (EPL or embryonic death (ED (first 42 days and fetal losses (after 42 days. Diagnosis of the causes of pregnancy loss is often very challenging. Many of the causes of EPL remain poorly documented but studies on embryo development and embryo-uterine interaction have been able to shed some light on predisposing factors. Fetal losses or abortions are dominated by infectious causes and particularly bacterial placentitis. Detailed reviews of pregnancy loss were recently published by the authors (Tibary et al., 2012; Tibary and Pearson, 2012; Tibary et al., 2014. The objective of this paper is to provide an overview of the epidemiology, etiology, diagnosis and prevention of pregnancy loss in the mare.

Spontaneous abortion (SA) occurs before 20 gestational weeks. Approximately, half of recurrent SA has no identifiable cause. No report has yet been investigated the possible involvement of lncRNA in pregnancy loss. Sixteen pairs of pregnancies with spontaneous abortions (SA) and induced abortions (IA) were studied. Embryonic sacs and decidua were collected for each pregnancy. A Human LncRNA Array was employed to profile genomewide lncRNAs, which were then validated by RT-PCR. Differentially expressed lncRNAs were identified. Biological pathways were categorized into six major groups: infection and inflammation, metabolism, signaling and transcriptional regulation, smooth muscle contraction, cell process, and coagulation. Infection and inflammation pathways regulated by lncRNAs were determined as the predominant pathogenetic factors underlying the SA. Finding that antisense lncRNAs have been either up- or down-regulated suggests that they may have both cis- and trans-regulations. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Antiphospholipid antibodies (APA are associated with thrombosis, thrombocytopenia and fetal loss but they occur in a variety of diseases. Despite many efforts, a correlation between the specificity of particular subgroups of APA and particular clinical situations remains to be established. The antigens at the origin of APA remain to be identified. We discuss here the possible links between cell apoptosis or necrosis, leading to plasma membrane alterations, and the occurrence of APA in response to sustained stimulation. The pathogenic potential of APA is also considered with respect to recurrent pregnancy loss.

Full Text Available The recent increase in heterotopic pregnancies has been largely attributed to the increased use of assisted reproduction technologies. We report the rare case of a multiparous woman with a spontaneous conception resulting in a triplet heterotopic pregnancy: a twin intrauterine pregnancy and a single right tubal ectopic pregnancy. Heterotopic pregnancy is a rare and potentially life-threatening condition in which simultaneous gestations occur at 2 or more implantation sites. It is infrequent in natural conception cycles, occurring in 1:30 000 pregnancies. However, the prevalence is rising with the increased use of assisted reproduction techniques to that of 1:100 to 1:500 in these patient subgroups, highlighting the need to incorporate it into a clinician’s diagnostic algorithm.

Placental infarction or abruption, recurrent pregnancy loss and pre-eclampsia are thought to arise due to defects within the placental vascular bed. Deficiencies of vitamin B12 and folate, or other abnormalities within the methionine-homocyst(e)ine pathway have been implicated in the development of such placental diseases. We conducted a systematic literature review to quantify the risk of placental disease in the presence of these metabolic defects. Studies were identified through OVID Medline between 1966 and February 1999. Terms relating to the measurement of vitamin B12, folic acid, methylenetetrahydrofolate reductase or homocyst(e)ine were combined with those of pre-eclampsia, placental abruption/infarction or spontaneous and habitual abortion. Human studies comprising both cases and controls and published in the English language were accepted. Their references were explored for other publications. Data were abstracted on the matching of cases with controls, the mean levels of folate, B12 or homocyst(e)ine in each group or the frequency of the homozygous state for the thermolabile variant of methylenetetrahydrofolate reductase. The definition of 'abnormal' for each exposure was noted and the presence or absence of the exposure of interest for each outcome was calculated as an absolute rate with a 95 per cent confidence interval. The crude odds ratios were calculated for each study and then pooled using a random effects model. Eighteen studies were finally included. Eight studies examined the risk of placental abruption/infarction in the presence of vitamin B12 or folate deficiency, or hyperhomocyst(e)inaemia. Folate deficiency was a prominent risk factor for placental abruption/infarction among four studies, though not statistically significant (pooled odds ratio 25.9, 95 per cent CI 0.9-736.3). Hyperhomocyst(e)inaemia was also associated with placental abruption/infarction both without (pooled odds ratio 5.3, 95 per cent CI 1.8-15.9) and with methionine

Spontaneous coronary artery dissection (SCAD) is a non-atherosclerotic, non-traumatic cause of coronary artery dissection. SCAD is the most common cause of myocardial infarction in pregnancy or the postpartum period and results in significant cardiovascular morbidity and mortality in the pregnant population. It is important to consider pregnancy-associated spontaneous coronary artery dissection (PASCAD) high on the differential for a pregnant woman who presents with symptoms consistent with acute coronary syndrome. Management of these patients requires a thoughtful, multidisciplinary approach, with consideration of conservative management if possible. Counseling regarding future pregnancies is also critical and requires compassionate care. Given our limited understanding of SCAD, including PASCAD, more data and research are needed to help guide diagnosis, management, and determination of prognosis.

BACKGROUND Although an association between thrombophilia and pregnancy loss has been observed in many studies, little is known about the pathophysiological mechanisms behind this association. Considering the association between thrombophilia and pregnancy loss, the efficacy of antithrombotic therapy for women with pregnancy loss (with or without thrombophilia) has been studied for the past 30 years. METHODS We performed a comprehensive review of the literature on the strength of the association between thrombophilia and pregnancy loss, the pathophysiological mechanisms and the efficacy of antithrombotic therapy to increase the chance of live birth. RESULTS The association between pregnancy loss and thrombophilia varies according to the type of thrombophilia (e.g. antiphospholipid syndrome versus forms of inherited thrombophilia) and according to the type of pregnancy loss (single versus recurrent pregnancy loss and early versus late pregnancy loss). Thrombophilia may induce thrombosis in decidual vessels or impair placentation through hypercoagulability and inflammation, but these hypotheses need further verification. For women with antiphospholipid syndrome, evidence from small-sized trials suggests a beneficial effect of antithrombotic therapy but additional randomized controlled trials are essential to confirm this. Whether antithrombotic therapy increases the chance of live birth in women with inherited thrombophilia is unknown. Recent randomized controlled trials have consistently shown that antithrombotic therapy does not increase the chance of live birth in women with unexplained recurrent miscarriage. CONCLUSIONS There are large gaps in knowledge and a lack of evidence for treatment of women with pregnancy loss with thrombophilia. To provide a solid base for clinical practice, further studies on the role of coagulation in reproduction, as well as international collaborations in randomized controlled trials of antithrombotic therapy in women with pregnancy

Following implantation, the maintenance of the pregnancy is dependent on a multitude of endocrinological events that will eventually aid in the successful growth and development of the fetus. Although the great majority of pregnant women have no pre-existing endocrine abnormalities, a small number of women can have certain endocrine alterations that could potentially lead to recurrent pregnancy losses. It is estimated that approximately 8 to 12% of all pregnancy losses are the result of endocrine factors. During the preimplantation period, the uterus undergoes important developmental changes stimulated by estrogen, and more importantly, progesterone. Progesterone is essential for the successful implantation and maintenance of pregnancy. Therefore, disorders related to inadequate progesterone secretion by the corpus luteum are likely to affect the outcome of the pregnancy. Luteal phase deficiency, hyperprolactinemia, and polycystic ovarian syndrome are some examples. Several other endocrinological abnormalities such as thyroid disease, hypoparathyroidism, uncontrolled diabetes, and decreased ovarian reserve have been implicated as etiologic factors for recurrent pregnancy loss.

The hepatic hematoma or rupture appear in 1 of every 100,000 pregnancies. The most common causes of hepatic hematoma in pregnancy are severe preeclampsia and HELLP syndrome; some predisposing factors are seizures, vomiting, labor, preexistent hepatic disease and trauma. A 33 year old primigravid with a normal 33 week twin pregnancy presented abdominal pain and hypovolemic shock due to spontaneous subcapsular hepatic hematoma; laparoscopy was performed to evaluate the possibility of rupture, which was not found, later emergency cesarean section was carried out followed by hepatic hematoma drainage and abdominal packaging by laparoscopy. After surgery the flow through drainage was too high additionally hemodynamic instability and consumption coagulopathy. Abdominal panangiography was performed without identifying bleeding areas. Intesive care was given to the patient evolving satisfactorily, was discharged 19 days after the event. Seven months later she had laparoscopic cholecystectomy due to acute litiasic colecistitis. We found 5 cases in literatura about hepatic hematoma during pregnancy no related to hypertensive disorders of pregnancy; these were related to hepatoma, amebian hepatic abscess, falciform cell anemia, cocaine consumption and molar pregnancy. Hepatics hematomas have high morbidity and mortality so is significant early diagnosis and multidisciplinary approach.

Common established causes include uterine anomalies, antiphospholipid syndrome, hormonal and metabolic disorders, and cytogenetic abnormalities. Other etiologies have been proposed but are still considered controversial, such as chronic endometritis, inherited thrombophilias, luteal phase deficiency, and high sperm DNA fragmentation levels. Over the years, evidence-based treatments such as surgical correction of uterine anomalies or aspirin and heparin for antiphospholipid syndrome have improved the outcomes for couples with recurrent pregnancy loss. However, almost half of the cases remain unexplained and are empirically treated using progesterone supplementation, anticoagulation, and/or immunomodulatory treatments. Regardless of the cause, the long-term prognosis of couples with recurrent pregnancy loss is good, and most eventually achieve a healthy live birth. However, multiple pregnancy losses can have a significant psychological toll on affected couples, and many efforts are being made to improve treatments and decrease the time needed to achieve a successful pregnancy. This article reviews the established and controversial etiologies, and the recommended therapeutic strategies, with a special focus on unexplained recurrent pregnancy losses and the empiric treatments used nowadays. It also discusses the current role of preimplantation genetic testing in the management of recurrent pregnancy

Spontaneous coronary artery dissection (SCAD) is the most common cause of pregnancy-associated myocardial infarction and remains poorly characterized. This study sought to assess presentation, clinical factors, and outcomes of pregnancy-associated spontaneous coronary artery dissection (P-SCAD) compared with spontaneous coronary artery dissection not associated with pregnancy (NP-SCAD). A Mayo Clinic registry was established in 2010 to include comprehensive retrospective and prospective SCAD data. Records were reviewed to identify women who were pregnant or ≤12 weeks postpartum at time of SCAD. Complete records were available for 323 women; 54 women met criteria for P-SCAD (4 during pregnancy) and they were compared with 269 women with NP-SCAD. Most events occurred within the first month postpartum (35 of 50). Compared with NP-SCAD, P-SCAD patients more frequently presented with ST-segment elevation myocardial infarction (57% vs. 36%; p = 0.009), left main or multivessel SCAD (24% vs. 5%; p vs. 14%; p = 0.0027, respectively), and left ventricular function ≤35% (26% vs. 10%; p = 0.0071). Among women with imaging of other vascular territories, P-SCAD was less likely with a diagnosis of fibromuscular dysplasia and extracoronary vascular abnormalities (42% vs. 64%; p = 0.047; and 46% vs. 77%; p = 0.0032, respectively). Compared with U.S. birth data, women with P-SCAD were more often multiparous (p = 0.0167), had a history of infertility therapies (p = 0.0004), and had pre-eclampsia (p = 0.001). On long-term follow-up (median 2.3 years) recurrent SCAD occurred in 51 patients, with no difference in the Kaplan Meier 5-year recurrence rates (10% vs. 23%; p = 0.18). P-SCAD patients had more acute presentations and high-risk features than women with NP-SCAD did. The highest frequency of P-SCAD occurred during the first postpartum month and P-SCAD patients less often had extracoronary vascular abnormalities. Hormonal, hemodynamic variations, and yet

Spontaneous heterotopic pregnancy is a rare clinical condition in which intrauterine and extrauterine pregnancies occur at the same time. It is rare, estimated to occur in 1 in 30,000 pregnancies. The case was a 38-year-old woman with spontaneously conceived heterotopic pregnancy. She was admitted to our center with hypovolemic shock. Focused assessment sonography for trauma examination in emergency department showed large amount of free fluid in peritoneal cavity. She was managed surgical laparotomy. Considering spontaneous pregnancies, physician should be aware of the possibility of heterotopic pregnancy in all reproductive age women, especially those with history of recent abortion. It can occur without any predisposing risk factors. Patients should be informed about possible side effects of nonprescription medicines, and also the health care centers must be safe peaceful environment for them without severe legal consequences.

Ulipristal acetate, a progesterone receptor modulator, pharmacologically inhibits endometrial proliferation and thereby prevents pregnancy. It is primarily used as emergency contraception, but also for the treatment of fibroids in women of reproductive age. There have been no published cases of pregnancy, while on therapy with ulipristal acetate. In this article, we present a case report of spontaneous pregnancy during ulipristal acetate therapy. To our knowledge, this is the first patient with spontaneous conception, while on ulipristal acetate treatment. There were no drug-related complications, and the pregnancy resulted in the delivery of a healthy baby. © 2017 John Wiley & Sons Ltd.

Two previous case-control studies observed associations between specific food groups and risk of miscarriage; however, to our knowledge, no previous studies have investigated dietary patterns and risk of pregnancy loss. We aimed to assess prepregnancy adherence to the alternate Healthy Eating Index 2010 (aHEI-2010), alternate Mediterranean diet (aMED), and Fertility Diet (FD) and risk of pregnancy loss. Our prospective cohort study included 15,950 pregnancies reported by 11,072 women in the Nurses' Health Study II between 1992 and 2009. Diet was assessed every 4 y starting in 1991 by using a validated food-frequency questionnaire. Prepregnancy dietary pattern scores were computed as the sum of a woman's score on each pattern's predefined components. Multivariable log-binomial regression models with generalized estimating equations were used to estimate RRs and 95% CIs. Incident spontaneous abortions and stillbirths were reported in 2756 (17.3%) and 120 (0.8%) pregnancies, respectively. None of the 3 dietary patterns were associated with risk of pregnancy loss. In the multivariable model, RR of pregnancy loss for a 1-SD increase in score was 1.02 (95% CI: 0.98, 1.05) for the aMED pattern, 1.01 (95% CI: 0.98, 1.05) for the aHEI-2010 pattern, and 0.98 (95% CI: 0.95, 1.01) for the FD pattern. Results were consistent when pregnancy loss was classified as either a spontaneous abortion (loss at <20 wk) or a stillbirth (loss at ≥20 wk). Prepregnancy adherence to several dietary patterns was not associated with risk of pregnancy loss. © 2014 American Society for Nutrition.

Spontaneous abortion is one of the most important complications of pregnancy with short and long adverse psychological effects on women. This study assesses the implications of a spontaneous abortion history has on women's psychiatric symptoms and pregnancy distress in subsequent pregnancy less than one years after spontaneous abortion. A case-control study was conducted on pregnant women of Babol city from September 2014 to May 2015. In this study, 100 pregnant women with spontaneous abortion history during a year ago and 100 pregnant women without spontaneous abortion history were enrolled. All the participants in two groups completed the Symptom Checklist-90-Revised (SCL-90-R), and pregnancy Distress Questionnaire (PDQ). Women with spontaneous abortion history had significantly higher mean of many subscales of SCL-90 (depression, anxiety, somatization, obsessive-compulsiveness, interpersonal sensitivity, psychoticism, hostility, paranoid, and Global Severity Index) more than women without spontaneous abortion history. Also, women with spontaneous abortion history had significantly higher mean of two subscales of PDQ concerns about birth and the baby, concerns about emotions and relationships) and total PDQ more than women without spontaneous abortion history. Pregnant women with less than a year after spontaneous abortion history are at risk of psychiatric symptoms and pregnancy distress more than controls. This study supports those implications for planning the post spontaneous abortion psychological care for women, especially women who wanted to be pregnant during 12 month after spontaneous abortion.

Recurrent Pregnancy Loss (RPL) affects public health and directly compromises the quality of life of hundreds of women, with a detrimental effect on their physical and mental health. Approximately 50% of RPL are not associated to any of the currently known etiology and will be considered idiopathic. Recently, it has been demonstrated that the expression of annexin 5 (ANXA5), a protein found on the trophoblastic surface, plays a fundamental role in the development of pregnancy due to its immunomodulator and anticoagulant function at the placentary level. Some genetic haplotypes of ANXA5 are associated to alterations in the expression of this gene, such as haplotype M2 which is associated to a decrease in the expression of ANXA5. The presence of this haplotype is related to the following conditions occurring during pregnancy: RPL, foetal intrauterine growth restriction, low child weight at birth, preeclampsia and maternal pulmonary thromboembolism. This review describes the structure, function and genetic expression of ANXA5, as well as its possible implication in RPL.

Full Text Available ABSTRACT: Introduction & Objective: Heterotopic pregnancy refers to the simultaneous occurrence of pregnancy intrauterine and outside of uterine corpus. It is most often manifested in women who have undergone artificial reproductive technology (ART but rarely occurs spontaneously. Heterotopic pregnancy still remains as a diagnostic and therapeutic challenge to practitioners. In this situation physicians should have high suspicion for diagnosis and intrauterine pregnancy protection. This study reported a case of ruptured spontaneous heterotopic pregnancy. Case: A 32 year-old woman with abdominal pain, nausea, vomiting and hypovolumic shock in 1386 referred to emergency department in Sanandaj hospital. She reported one previous cesarean section. On examination, the patient's abdomen was distended. She had generalized tenderness and rebound tenderness in abdomen. The ultrasonographic examination revealed large amount of fluid in pelvic and abdominal cavity with a large hematoma in right adnex but there was intrauterine pregnancy at 7 weeks with normal fetal heart activity. She underwent laparotomy for heterotopic pregnancy and ruptured tube with tubal pregnancy removed. Intrauterine pregnancy continued without problem and led to birth of a healthy female neonate. Conclusion: Physicians should be quite cautious of heterotopic pregnancy in woman at reproductive age. Any abnormality on physical examination or ultrasonography of a patient with intrauterine pregnancy and abdominal pain should heighten the clinician's suspicion for heterotopic pregnancy

The diagnosis is usually made intraoperatively and levels of serum BHCG and ultrasound has not been useful in the diagnosis of bilateral tubal ectopic pregnancy. A 33-year-old woman with 8 weeks amenorrhea and sever lower abdominal pain was admitted. A transvaginal pelvic ultrasound revealed left adnexal mass and massive fluid collection in the pelvis and abdomen. The serum BHCG was 5,700 mIU/ml and in laparotomy bilateral unruptured tubal pregnancy was noted. Left salpingectomy and right salpingostomy were performed. The diagnosis of bilateral spontaneous tubal ectopic pregnancy is usually made intraoperatively. Both tubes at the time of surgery should be closely examined in order to prevent maternal morbidity and mortality.
Full Text Available Ectopic pregnancy is a significant problem in women of childbearing potential and affects up to 2% of them. The most common ectopic pregnancy localization is the ampullary area of the Fallopian tube. Patient with spontaneous ectopic pregnancy located in the tubal stump after an ipsilateral adnexectomy performed with a laparotomy due to mucinous cystadenoma was operated by laparoscopy. Remnant of Fallopian tube with ectopic pregnancy was removed. The most important lecture from this case is when adnexectomy or salpingectomy is performed, it should be done in the isthmic part, without leaving any remnant.

Cigarette smoking during pregnancy increases risks of poor pregnancy outcomes including miscarriage and stillbirth (pregnancy loss), but the effect of smoking on pregnancy loss among HIV-infected women has not been explored. Here, investigated the impact of smoking on risk of pregnancy loss among HIV-positive and HIV-negative women, and estimated the potential impact of realistic smoking cessation interventions on risk of pregnancy loss among HIV-positive women. We analyzed pregnancy outcomes in HIV-positive and HIV-negative participants in the Women's Interagency HIV Study between 1994 and 2014. We estimated effects of current smoking at or immediately before pregnancy on pregnancy loss; we controlled for confounding using regression approaches, and estimated potential impact of realistic smoking cessation interventions using a semiparametric g-formula approach. Analysis examined 1033 pregnancies among 659 women. The effect of smoking on pregnancy loss differed dramatically by HIV status: adjusted for confounding, the risk difference comparing current smokers to current nonsmokers was 19.2% (95% confidence limit 10.9-27.5%) in HIV-positive women and 9.7% (95% confidence limit 0.0-19.4%) in HIV-negative women. These results were robust to sensitivity analyses. We estimated that we would need to offer a realistic smoking cessation intervention to 36 women to prevent one pregnancy loss. Smoking is a highly prevalent exposure with important consequences for pregnancy in HIV-positive pregnant women in the United States, even in the presence of potent highly active antiretroviral therapy. This evidence supports greater efforts to promote smoking cessation interventions among HIV-positive women, especially those who desire to become pregnant.
Sudden hearing loss directly associated with pregnancy or birth is a little known and rare occurrence. The temporary, unilateral, low-frequency sensorineural hearing loss in this case was reported after the birth of the patient\\'s first child, and again during the third trimester of her second pregnancy.

Full Text Available Spontaneous adrenal hemorrhage (SAH is seen in the absence of trauma or adrenal tumor in adrenal glands. The incidence of SAH has been reported from 0.14% to 1.1% and it usually involves the right gland. During pregnancy, idiopathic unilateral SAH has been reported rarely. We present a case which comes to emergency department with an acute abdominal pain and the test results showed spontaneous left SAH.
Full Text Available Spontaneous adrenal hemorrhage is an acute hemorrhage during pregnancy, which can be tragic for the mother and the baby. We report a unique spontaneous hemorrhage during pregnancy in a case with horseshoe kidney with separated adrenal, presented for the first time in the world. Computed tomography scan showed a horseshoe kidney fused with left normal kidney. Interestingly the adrenal gland was remained in right flank and separated from the horseshoe kidney, which prepares a probable physical stress for the hemorrhage. Diagnosis and surgery were done successfully and the case was fully recovered after several days.
Full Text Available Introduction. Heterotopic pregnancy is a rare complication usually seen in populations at risk for ectopic pregnancy or those undergoing fertility treatments. It is a potentially dangerous condition occurring in only 1 in 30,000 spontaneous pregnancies. With the advent of Assisted Reproduction Techniques (ART and ovulation induction, the overall incidence of heterotopic pregnancy has risen to approximately 1 in 3,900 pregnancies. Other risk factors include a history of pelvic inflammatory disease (PID, tubal damage, pelvic surgery, uterine Mullerian abnormalities, and prior tubal surgery. Heterotopic pregnancy is a potentially fatal condition, rarely occurring in natural conception cycles. Most commonly, heterotopic pregnancy is diagnosed at the time of rupture when surgical management is required. Case. This paper represents two cases of heterotopic pregnancies as well as a literature review. Conclusion. Heterotopic pregnancy should be suspected in patients with an adnexal mass, even in the absence of risk factors. Clinicians must be alert to the fact that confirming an intrauterine pregnancy clinically or by ultrasound does not exclude the coexistence of an ectopic pregnancy. A high index of suspicion in women is needed for early and timely diagnosis, and management with laparotomy or laparoscopy can result in a favorable and successful obstetrical outcome.

The term "miscarriage" refers to the end of pregnancy before the 22nd week of gestation, or taking into account the criterion of foetal weight (less than 500 g). Approximately 15-20% of recognized pregnancies and miscarriage involve spontaneous expulsion of the blastocyst from the uterine cavity. This constitutes about 80% of miscarriages in the first 12 weeks of gestation. The literature lists a number of factors which cause the loss of pregnancies. The most frequently cited causes of abortion are: genetic, anatomical, immunological and hormonal factors, and infections. A large number of miscarriages remain unexplained (idiopathic miscarriages). Clinical signs of miscarriage include bleeding and pain. Bleeding or spotting is the earliest sign of miscarriage. Data from the patient's history, physical examination, ultrasound examination and tests for hCG level can enable diagnosis of bleeding in early pregnancy, help to assess the degree of risk, and implement an appropriate treatment regimen and care for pregnant women adapted to their needs. Loss of pregnancy is an interdisciplinary problem involving obstetrics, epidemiology, public health, psychology, and other specialities. The role of medical personnel in the care of women after the loss of a child, regardless of the week and therapeutic procedures, as well as for giving adequate information regarding the rights of women after pregnancy loss. The obligation to inform women of their rights concerns medical staff, and it is important to promote knowledge in this field among doctors, nurses and midwives who care for women after miscarriage.
It is known that most cases of Ovarian Hyperstimulation Syndrome (OHSS) are associated with the therapies for ovulation induction. However, OHSS may rarely be associated with a spontaneous ovulatory cycle, usually in the case of multiple gestations, hypothyroidism or polycystic ovary syndrome. We report a case of ...
She remained on admission for the rest of her pregnancy. She had Dexamethasone 12 mg intra-muscularly for 2 doses at 31 weeks gestation. Her general condition remained stable except for occasional difficulty breathing which responded to postural changes. At 37 weeks gestation, she had elective caesarean section.
Full Text Available Spontaneous OHSS in a term pregnancy is extremely rare. The aim of this study is to present a case of spontaneous ovarian hyperstimulation syndrome (OHSS in a term pregnancy. A 29-year-old primigravida woman conceived spontaneously and was observed up until 35 weeks of gestation. During this time the patient had a normal pregnancy with normal ovaries. She applied to the current clinic during the 37th week of gestation with complaints of rapid weight gain, abdominal disturbance, and pain. Ultrasound examination showed large bilateral ovaries with multiple follicles and mild ascites. At 39 weeks of gestation, the ovaries were the same as detected previously, and a caesarean section was performed due to fetal macrosomia. A healthy female foetus weighing 4060 gr was delivered. The enlarged bilateral ovaries containing multiple follicles were drilled with electrocautery. The ovaries returned to a near normal state for two weeks after the birth. There are no reported cases of spontaneous OHSS in late pregnancy in the literature. Ovarian drilling may be useful during caesarean section. [Cukurova Med J 2015; 40(3.000: 623-626

Although antibiotics are widely used during pregnancy, evidence regarding their fetal safety remains limited. Our aim was to quantify the association between antibiotic exposure during pregnancy and risk of spontaneous abortion. We conducted a nested case-control study within the Quebec Pregnancy Cohort (1998-2009). We excluded planned abortions and pregnancies exposed to fetotoxic drugs. Spontaneous abortion was defined as having a diagnosis or procedure related to spontaneous abortion before the 20th week of pregnancy. The index date was defined as the calendar date of the spontaneous abortion. Ten controls per case were randomly selected and matched by gestational age and year of pregnancy. Use of antibiotics was defined by filled prescriptions between the first day of gestation and the index date and was compared with (a) non-exposure and (b) exposure to penicillins or cephalosporins. We studied type of antibiotics separately using the same comparator groups. After adjustment for potential confounders, use of azithromycin (adjusted odds ratio [OR] 1.65, 95% confidence interval [CI] 1.34-2.02; 110 exposed cases), clarithromycin (adjusted OR 2.35, 95% CI 1.90-2.91; 111 exposed cases), metronidazole (adjusted OR 1.70, 95% CI 1.27-2.26; 53 exposed cases), sulfonamides (adjusted OR 2.01, 95% CI 1.36-2.97; 30 exposed cases), tetracyclines (adjusted OR 2.59, 95% CI 1.97-3.41; 67 exposed cases) and quinolones (adjusted OR 2.72, 95% CI 2.27-3.27; 160 exposed cases) was associated with an increased risk of spontaneous abortion. Similar results were found when we used penicillins or cephalosporins as the comparator group. After adjustment for potential confounders, use of macro-lides (excluding erythromycin), quinolones, tetracyclines, sulfonamides and metronidazole during early pregnancy was associated with an increased risk of spontaneous abortion. Our findings may be of use to policy-makers to update guidelines for the treatment of infections during pregnancy. © 2017

The definition of recurrent pregnancy loss varies according different authors and consensus: the American Society for Reproductive Medicine (ASRM) defines RPL when two or more pregnancy losses occur, and the European Society of Human Reproduction and Embryology (ESHRE) defines it as three or more pregnancy losses, not necessarily intrauterine. To this day, there is no uniform approach that serves as a guide in the diagnosis and treatment of this condition; this is why, in up to 50% of the cases of RPL, it will not be possible to identify the specific etiology. To report on the recurrent pregnancy loss, in order to harmonize concepts and suggest a diagnosis and treatment for this condition approach. The search strategy included, but was not limited to keywords like: recurrent abortion, infertility, habitual abortion, primary antiphospholipid syndrome, lupus anticoagulant, anti-cardiolipin antibodies and anti B2 glycoprotein I.

Preterm birth occurs before 37 completed weeks, its causes are multifactorial and vary according to the gestational age, ethnicity and geographical context. Although several medical/social factors have been clearly identified, over 50% of cases are unknown or unclear; however, psychopathological components emerge as potentially important risk factors. To determine the relationship between the presence of stress during pregnancy and spontaneous preterm birth. Through a study of cases and controls in a level III hospital, with a sample of 360 patients during the period from March to November of 2013, where sociodemographic characteristics were collected. In addition, they were applied scales social adjustment, coping strategies and social support. Logistic regression models were developed; psychological, biological and social. Based on the significant variables in each of these generated a final one. The final model was found that stress during pregnancy increases the odds of spontaneous preterm birth 1.91 times (adjusted OR=2.91; 95%CI, 1.67-5.08; P<.05). Other significant variables were: history of preterm delivery, unplanned pregnancy, no emotional support, rural residence, inadequate prenatal care and non-stable partner. The findings support the hypothesis that stress during pregnancy is associated with spontaneous preterm delivery. Copyright © 2015 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

Full Text Available Pregnancy in patients with pan-hypopituitarism following surgery of pituitary adenoma is rare and considered high risk. Hormonal dysfunction in these patients involves more than one axis (gonadotrophic, thyroidal, and adrenal. However, advance in infertility treatment have led to the increased pregnancy rate in hypopituitarism women. We present a case of nonfunctioning pituitary macroadenoma, who after pituitary surgery (hypophysectomy developed hypopituitarism followed by multiple tuberculoma brain with hydrocephalus with arachnoiditis. She conceived spontaneously after 9 years of pituitary surgery and carried her pregnancy to the term. Elective caesarean section was done at 38 weeks and both infant and mother are well. The case highlights the rarity of the phenomenon and the safe outcome of the pregnancy with proper replacement.

Spontaneous and recurrent pregnancy loss are common complications of pregnancy resulting from varied causes including antiphospholipid syndrome (APS). Treatment of women with APS increases the chance of a subsequent successful pregnancy. The study aimed to find the prevalence of lupus anticoagulants (LA) and anticardiolipin antibodies (ACAs) in women with spontaneous/recurrent fetal loss and compare with women with normal obstetric history. Hundred women with spontaneous/recurrent fetal loss and 50 healthy pregnant controls were tested for LA by complete blood counts, Prothrombin time, Activated partial thromboplastin time (APTT), LA sensitive APTT and dilute Russell viper venom time (dRVVT) (screening and confirmatory) and ACAs (ELISA). LA was detected in 15 % patients using dRVVT confirmatory test and ACA in 5 %, all controls being negative. Twenty one % patients were detected by LA sensitive APTT (sensitivity 92.9 %, specificity 100 %) and 100 % with dRVVT screening test (sensitivity 98.8 %, specificity 100 %). We recommend that screening for antiphospholipid antibodies must be done in women with spontaneous/recurrent foetal loss even in the absence of other clinical manifestations using a combination of tests.

To determine prenatal methods to predict and prevent spontaneous preterm birth in asymptomatic twin pregnancies. Articles were searched using PubMed, Embase and Cochrane library. Uterine activity monitoring and bacterial vaginosis screening are not useful to predict preterm birth (EL2 and EL3 respectively). Current literature data are contradictory and insufficient to determine whether fetal fibronectin and digital cervical assessment are predictors of preterm birth. History of preterm birth (EL4), and cervical length measurement by transvaginal ultrasonography (EL2) predict preterm birth. Nevertheless, there are no intervention studies that have evaluated cervical length measurement in the prevention of preterm birth. Hospital bedrest, prophylactic tocolytic and progesterone therapy, and prophylactic cervical cerclage in patients with or without short cervix have not been shown to be effective in preventing preterm birth. Prenatal methods to prevent spontaneous preterm birth in asymptomatic twin pregnancies are currently very limited. Copyright © 2009 Elsevier Masson SAS. All rights reserved.

Epidural abscess is a rare complication of regional anesthesia, and spontaneous formation is even more uncommon. Diabetes mellitus, concomitant infection, intravenous drug use, and immune suppression are risk factors for spontaneous epidural abscess. A 29-year-old white woman presented at 28 weeks of estimated gestational age reporting an intermittent headache. She had Horner syndrome and was hospitalized. A cervicothoracic epidural abscess was diagnosed. Surgical decompression and parenteral antibiotics resulted in complete resolution of neurologic symptoms. Cultures were positive for methicillin-resistant Staphylococcus aureous. Spontaneous epidural abscess is a rare condition and diagnosis is often delayed. The finding of Horner syndrome led to imaging of the cervical spine and diagnosis of epidural abscess. Early intervention resulted in resolution of neurologic symptoms and a successful pregnancy outcome.

Recurrent pregnancy loss (RPL) is a multifactorial condition. Approximately half of patients with RPL will have no explanation for their miscarriages. De novo chromosome abnormalities are common in sporadic and recurrent pregnancy loss. Testing for embryonic abnormalities can provide an explanation for the miscarriage in many cases and prognostic information. Regardless of the cause of RPL, patients should be reassured that the prognosis for live birth with an evidence-based approach is excellent for most patients. The authors review current evidence for the evaluation and treatment of RPL and explore the proposed use of newer technology for patients with RPL. Copyright © 2015 Elsevier Inc. All rights reserved.

Endocrine disorders have been frequently linked to recurrent pregnancy loss (RPL). Because embryo attachment and early implantation are exquisitely controlled by the local hormonal milieu, endocrine-related pregnancy failures are likely to occur early in gestation. Thyroid disorders, luteal phase defects, and polycystic ovary syndrome are the endocrine abnormalities most commonly associated with RPL. In this review we discuss new concepts in the pathophysiology and treatment of these diseases with the ultimate goal of improving pregnancy maintenance. We have also included our recommendations on testing and treatment of women with isolated and repeated pregnancy failure that is believed to be at least partially mediated by newly defined hypothyroidism, thyroid autoimmunity, luteal phase defects, obesity, and polycystic ovary syndrome. © Thieme Medical Publishers.

We sought to estimate the rate of spontaneous resolution of asymptomatic Chlamydia trachomatis in pregnancy and to evaluate factors associated with its resolution. A cohort of women enrolled in a large multicenter randomized bacterial vaginosis antibiotic trial (metronidazole versus placebo) that, when randomly allocated, had asymptomatic C trachomatis diagnosed by urine ligase chain reaction (from frozen archival specimens) between 16(0/7) and 23(6/7) weeks were included. The urine ligase chain reaction is a highly accurate predictor of genital tract chlamydial infection. A follow-up ligase chain reaction was performed between 24(0/7) and 29(6/7) weeks. A total of 1,953 women were enrolled in the original antibiotic trial; 1,547 (79%) had ligase chain reaction performed both at randomization and follow-up. Women receiving antibiotics effective against Chlamydia between randomization and follow-up or having symptomatic Chlamydia infection were excluded (26 women). Of the 140 women (9%) who were diagnosed as positive via the initial ligase chain reaction assay, 61 (44%) had spontaneous resolution of Chlamydia by the follow-up ligase chain reaction assay. Factors associated with spontaneous resolution included older age (P = .02), more than 5 weeks from randomization to follow-up (P = .02), and a greater number of lifetime sexual partners (P = .02). Using a logistic regression model, maternal age and a greater-than-5-week follow-up interval remained significant; for every 5-year increase in maternal age, the odds of a positive result on the ligase chain reaction test at follow-up decreased by 40% (odds ratio 0.6; 95% confidence interval 0.4-0.9). Race, substance abuse, parity, and treatment with metronidazole were not associated with spontaneous resolution. Gram stain score and vaginal pH at randomization and follow-up also were not associated. The prevalence of asymptomatic C trachomatis in pregnancy was 9%; infection resolved spontaneously in almost half of these

Endocrine disruptions may be important in patients experiencing recurrent pregnancy loss (RPL). This review focuses on data available on RPL and the endocrine system to investigate relevant, and perhaps modifiable, endocrine factors of importance for the disorder. Evidence indicates that some hormones may be important as immune modulators and a better understanding of this interplay has potential for improving pregnancy outcome in RPL. To date there is a lack of consensus on the effect of endocrine treatment options in RPL and there is a strong need for large randomized-controlled trials.

occur within hours following ovulation, a discrepancy is theoretically possible. However, when comparing our results to those of prospective studies, no such difference was found. The equation used for estimating the date of pregnancy was estimated in IVF/ICSI pregnancies, which could lead to potential bias in spontaneous pregnancies. However, in our population, the observed bias was negligible. Non-fertile cycles and early pregnancy losses are necessarily overlooked because of the nature of our data. Because of the wider access to retrospective data and the potential bias in prospective studies of ovulation monitoring, this study should broaden the perspectives of future epidemiologic research in fertility and pregnancy monitoring.

Determine maternal and fetal characteristics of in vitro fertilization twin pregnancies in comparison with spontaneous twin pregnancies. Retrospective historical cohort study between 2011 and 2013. Statistical analysis was performed with SPSS 15.0 program and Epidat 3.0. A value of p<0.05 was considered statistically significant. 96 twin pregnancies met inclusive criteria with an incidence of 2.01%, of which 54.16% were spontaneous twin pregnancies and 45.83% in vitro fertilization twin pregnancies. Mean maternal age at delivery was higher in vitro fertilization twin pregnancies (p=0.004). The primigravidae were more frequent in vitro fertilization twin pregnancies group (p<0.001). Monochorionic pregnancies percentage was superior in spontaneous pregnancies (p=0.009). Amenorrhea at delivery was not a significant difference between cohorts (p=.9). Preterm rate was superior in spontaneous twin pregnancies group (p=0.003). However, "great preterm deliveries" were higher in in vitro fertilization twin pregnancies (p<0.001). Significant differences were not observed in fetal presentation at delivery, first-born child birth-weight or intrauterine growth retardation between the two groups. Nevertheless, the mean birth-weight of second-born spontaneously conceived twins was higher than second-born twins of the in vitro fertilization conceived group (p=0.027). Gestational pathology presented the same distribution in both cohorts. There was no significant difference in the mode of delivery between the two groups. Total perinatal mortality rate was 20,83%o and comprised 2 first born twins and 2 second born twins. Three of the stillbirths came from the spontaneous pregnancies group and one from the in vitro fertilization group. Perinatal death was secondary to stillbirths, which we found higher in spontaneously conceived twin pregnancies due to higher number of monochorionic pregnancies.

Hypothyroidism is a common endocrine disease. The frequency of pregnancy loss in women with known hypothyroidism as opposed to women with a later diagnosis of hypothyroidism has not been evaluated and compared with other common endocrine diseases. Population-based cohort study using Danish nationwide registers. All pregnancies in Denmark, 1997-2008, resulting in live birth (n = 732 533), spontaneous abortion (n = 112 487) or stillbirth (n = 2937) were identified together with information on maternal hypothyroidism, hyperthyroidism and diabetes. Cox model was used to estimate adjusted hazard ratio (aHR) with 95% confidence interval (95%CI) for spontaneous abortion and stillbirth, reference: no hypo- or hyperthyroidism or diabetes (n = 824 310). We identified 4951 pregnancies where maternal hypothyroidism was diagnosed before the pregnancy (group 1) and 2464 pregnancies where maternal hypothyroidism was diagnosed in the 2-year period after the pregnancy (group 2). In group 1, 825 pregnancies (16·7%) resulted in spontaneous abortion which was more frequent than in nonexposed (13·2%), (aHR 1·19 (95%CI 1·12-1·27)), and of the same magnitude as in hyperthyroidism (17·2%, P = 0·5) and diabetes (17·5%, P = 0·2) diagnosed before the pregnancy. In group 2, the frequency was 12·2% (aHR 0·92 (0·84-1·02)). In group 2, 16 pregnancies (0·65%) resulted in stillbirth which was more frequent than in nonexposed (0·36%), (aHR 1·81 (1·11-2·97)), of the same magnitude as in hyperthyroidism (0·82%, P = 0·5) and less frequent than in diabetes (2·9%, P Hypothyroidism increased the risk of both early and late pregnancy loss as did hyperthyroidism and in particular diabetes. We hypothesize that undetected or insufficiently treated maternal disease in the pregnancy may be of causal importance. © 2016 John Wiley & Sons Ltd.

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.

Lymphocytic hypophysitis(LH) is a rare but increasingly recognized autoimmune endocrine condition that causes partial or total hypopituitarism and is often associated with peripartum young women. We here report a 28-year-old patient who had a spontaneous and uneventful pregnancy following LH that had been treated with transspenoidal surgery and followed by anti-inflammatory agent. The woman failed to lactate and developed frontal headaches 3 months after normal delivery of her first child 3 years ago. Lab test showed the reduced concentrations of thyroxine, estradial and cortisol, suggesting hypopituitarism. Magnetic resonance imaging of the brain with contrast was performed and showed a uniformly enhancing pituitary mass with elevated optic chiasm. She underwent transsphenoidal surgery and histological examination of the resected specimen was consistent with lymphocytic hypophysitis. Anti-inflamation was started with prednisolone 40 mg per day because of a recurrence of headache that had completely recovered after surgery and regularly withdrawn to a long term maintenance dose of 10 mg per day. Physiological thyroxine replacement therapy was maintained. Her menstruation was restored without sex hormone replacement after 3 months. Three years after surgery, she got pregnant spontaneously and had normal breastfeeding after delivery. LH did not recur during this peripartum.

The ovarian hyperstimulation syndrome is the combination of increased ovarian volume, due to the presence of multiple cysts and vascular hyperpermeability, with subsequent hypovolemia and hemoconcentration. We report a case of spontaneous syndrome in a singleton pregnancy. This was a spontaneous pregnancy with 12 weeks of gestational age. The pregnancy was uneventful until 11 weeks of gestational age. After that, the pregnant woman complained of progressive abdominal distention associated with abdominal discomfort. She did not report other symptoms. In the first trimester, a routine ultrasonography showed enlarged ovaries, multiples cysts and ascites. Upon admission, the patient was hemodynamically stable, her serum β-hCG was 24,487mIU/mL, thyroid-stimulating hormone was 2.2µUI/mL and free T4 was 1.8ng/dL. All results were within normal parameters. However, levels of estradiol were high (10,562pg/mL). During hospitalization, she received albumin, furosemide and prophylactic dose of enoxaparin. The patient was discharged on the sixth hospital day. RESUMO A síndrome de hiperestimulação ovariana é a combinação do aumento dos ovários, devido à presença de múltiplos cistos e de hiperpermeabilidade vascular, com subsequente hipovolemia e hemoconcentração. Relata-se um caso de síndrome espontânea em uma gestação única. Trata-se de gravidez espontânea com 12 semanas de idade gestacional. A gravidez ocorreu sem intercorrências até 11 semanas de idade gestacional. Após, a gestante passou a se queixar de distensão abdominal progressiva, associada com desconforto abdominal. A paciente não relatava outros sintomas. A ultrassonografia de rotina no primeiro trimestre mostrou ovários aumentados com múltiplos cistos e ascite. No momento da internação, a paciente apresentava-se hemodinamicamente estável, com β-hCG sérico de 24.487mUI/mL, hormônio estimulante da tireoide de 2,2µUI/m e T4 livre de 1,8ng/dL, ou seja, valores dentro dos par

To evaluate the association between pregnancy loss history and adverse pregnancy outcomes. Pregnancy history was captured during a computer-assisted personal interview for 21,277 women surveyed in the National Survey of Family Growth (1995-2013). History of pregnancy loss (pregnancy loss. We estimated risk ratios for a composite measure of selected adverse pregnancy outcomes (preterm, stillbirth, or low birthweight) at first parity and in any future pregnancy, separately, using predicted margins from adjusted logistic regression models. At first parity, compared with having no loss, having 3+ previous pregnancy losses (adjusted risk ratio (aRR) = 1.66 [95% CI = 1.13, 2.43]), a maximum gestational age of loss(es) at ≥10 weeks (aRR = 1.28 [1.04, 1.56]) or having experienced a loss 24+ months ago (aRR = 1.36 [1.10, 1.68]) were associated with increased risks of adverse pregnancy outcomes. For future pregnancies, only having a history of 3+ previous pregnancy losses at first parity was associated with increased risks (aRR = 1.97 [1.08, 3.60]). Number, gestational age, and recency of pregnancy loss at first parity were associated with adverse pregnancy outcomes in U.S. women. Published by Elsevier Inc.

Recently assisted reproduction techniques are more common, which increases multiple pregnancies and adverse perinatal outcomes. Some authors report increased mortality in multiple pregnancies products obtained by techniques of assisted reproduction vs. conceived spontaneously, although other authors found no significant difference. To evaluate mortality rate of multiple pregnancies comparing those obtained by assisted reproduction vs. spontaneous conception. Retrospective, observational and comparative study. We included pregnant women with 3 or more products that went to the Unidad Médica de Alta Especialidad No. 23, IMSS, in Monterrey, NL (Mexico), between 2002-2008. We compared the number of complicated pregnancies and dead products obtained by a technique of assisted reproduction vs. spontaneous. 68 multiple pregnancies were included. On average, spontaneously conceived fetuses had more weeks of gestation and more birth weight than those achieved by assisted reproduction techniques (p = ns). 20.5% (14/68) of multiple pregnancies had one or more fatal events: 10/40 (25%) by assisted reproduction techniques vs. 4/28 (14%) of spontaneous multiple pregnancies (p = 0.22). 21/134 (16%) of the products conceived by assisted reproduction techniques and 6/88 (7%) of spontaneous (p assisted reproduction and 21% of the cases had one or more fatal events (11% more in pregnancies achieved by assisted reproduction techniques). 12% of the products of multiple pregnancies died (9% more in those obtained by a technique of assisted reproduction).

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 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 in women with PCOS. IR may play a significant role in EPL. Copyright 2009

Full Text Available Abstract Objective To describe management and clinical features observed in a patient's seven spontaneous pneumothoraces that developed during two consecutive pregnancies involving both hemithoraces. Materials and methods A 21 year old former smoker developed three spontaneous left pneumothoraces in the index pregnancy, having already experienced four right pneumothorax events in a prior pregnancy at age 19. Results Chest tubes were required in several (but not all hospitalizations during these two pregnancies. Following her fourth right pneumothorax, thoracoscopic excision of right apical lung blebs and mechanical pleurodesis was performed. The series of left pneumothoraces culminated in mini-thoracotomy and thoracoscopically directed mechanical pleurodesis. For both pregnancies unassisted vaginal delivery was performed with no adverse perinatal sequelae. With the exception of multiple pneumothoraces, there were no additional pregnancy complications. Conclusion Spontaneous pneumothorax in pregnancy is believed to be a rare phenomenon, yet the exact incidence is unknown. Here we present the first known case of multiple spontaneous pneumothoraces in two consecutive pregnancies involving both hemithoraces. Clinical management coordinated with obstetrics and surgical teams facilitated a satisfactory outcome for both pregnancies. The diagnosis of pneumothorax should be contemplated in any pregnant patient with dyspnea and chest pain, followed by radiographic confirmation.
Full Text Available Background: This study compared neonatal outcome and maternal complications in multiple pregnancies after assisted reproductive technologies (ART to spontaneous pregnancies. Materials and Methods: In this cross-sectional study, we reviewed medical records of 190 multiple pregnancies and births conceived by ART or spontaneous conceptions between 2004 and 2009 in Women Hospital. Obstetric history and outcomes were recorded and compared between these two groups. SPSS version 13 was used for data analysis. The results were analyzed using student’s t test, chi square and logistic regression (p<0.05. Results: There were 106 deliveries from spontaneous conceptions and 84 that resulted from ART. Parity history and mode of delivery significantly differed between the two groups (p<0.001. The ART group had significantly higher preterm labor and premature rupture of membranes (PROM whereas pregnanc-induced hypertension (PIH was higher in the spontaneous group (p=0.01. Newborn intensive care unit (NICU admission, duration of hospitalization, still birth and low gestational age were significantly higher in the ART group while neonatal jaundice was higher in the spontaneous group. Logistic regression analysis by considering neonatal complications as the dependent variable showed that respiratory distress syndrome (RDS, NICU admission and Apgar score were independent predictors for neonatal complications. Conclusion: Obstetric and neonatal outcomes must be considered in multiple pregnancies conceived by ART.

The spontaneous infarction of benign breast lesions is a rare entity and hence is not usually considered in the differential diagnosis during radiologic or clinical examination. There have been a few published cases of infarction during pregnancy and lactation. In this study we report the ultrasonographic and pathologic features of a spontaneous infarction of a lactating adenoma with acute mastitis and abscess and a spontaneously infarcted fibroadenoma.

The Weathering Effect is a theory that links stress exposure, over the life-course, with racial disparities in reproductive outcomes, through the effects of social adversity on a woman's body. The concept of maternal "weathering" captures cumulative somatic and psychological adversities that can exacerbate the effects of aging. Much of the evidence for weathering comes from observational studies linking self-report measures with reproductive outcomes. The purpose of this review is to explore biological mechanisms that underlie these observations. We focus on spontaneous abortion because this event is understudied despite evidence of racial disparities in this outcome. Spontaneous abortion is the most common pregnancy failure, and it happens early in pregnancy. Early pregnancy is a time most susceptible to the harmful effects of immune dysregulation that may, in part, result from adversities experienced before pregnancy begins. In exploring these mechanisms, we draw on well-defined signaling processes observed in the stressor-depression relationship. Pro-inflammatory dysregulation, for example, has particular relevance to immunological control occurring early in pregnancy. Early pregnancy immunologic changes affect the trajectories of pregnancy via control of trophoblastic invasion. Within the first few weeks of pregnancy, uterine derived cytokines operate within cytokine networks and play a critical role in this invasion. Programming for pro-inflammatory dysregulation can occur before conception. This dysregulation, brought into early pregnancy, has implications for viability and success of the index pregnancy. These patterns suggest early pregnancy health is susceptible to stress processing pathways that influence this immunologic control in the first six to eight weeks of pregnancy. In this review, we discuss the known mediating role of immune factors in the stressor-depression relationship. We also discuss how adversity experienced before the index pregnancy, or

To determine whether interpregnancy interval after the first spontaneous abortion has an effect on reproductive performance of women in their next pregnancy. A prospective cohort study was conducted on 4,619 women with history of spontaneous abortion in their first pregnancy. Of them 2,422 (52.4 %) conceived within 6 months of the miscarriage (group A) and 2,197 47.6 % after 12 months (group B). The primary outcome was abortion, live birth, termination, or ectopic pregnancy in the next pregnancy. Secondary outcomes were preterm delivery, low birth weight infants, caesarean section rate and occurrence of preeclampsia, placental abruption and induced labour in the second pregnancy. Women who conceived again within 6 months were less likely to have another abortion, termination, or ectopic pregnancy compared with women with interpregnancy interval more than 12 months. Women with an interpregnancy interval more than 12 months were less likely to have live birth in the second pregnancy and more likely to have a caesarean section, preterm delivery, or infant of low birth weight compared with women who conceived again within 6 months. Women who conceive within 6 months after their first spontaneous abortion have better reproductive outcomes and the lowest complication rates in their subsequent pregnancy.
Full Text Available INTRODUCTION: With the advent of assisted reproductive treatment options, the incidence of multiple pregnancies has increased. Although the need for elective single embryo transfer is emphasized time and again, its uniform applicability in practice is yet a distant goal. In view of the fact that triplet and higher order pregnancies are associated with significant fetomaternal complications, the fetal reduction is a commonly used option in such cases. This retrospective study aims to compare the perinatal outcome in patients with triplet gestation who have undergone spontaneous fetal reduction (SFR as against those in whom multifetal pregnancy reduction (MFPR was done. MATERIALS AND METHODS: In the present study, eighty patients with triplet gestation at 6 weeks were considered. The patients underwent SFR or MFPR at or before 12-13 weeks and were divided into two groups (34 and 46, respectively. RESULTS: Our study found no statistical difference in perinatal outcome between the SFR and MFPR groups in terms of average gestational age at delivery, abortion rate, preterm delivery rate, and birth weight. The study shows that the risk of aborting all fetuses after SFR is three times (odds ratio [OR] = 3.600, 95% confidence interval [CI] = 0.2794-46.388 that of MFPR in subsequent 2 weeks. There were more chances of loss of extra fetus in SFR (23.5% group than MFPR group (8.7% (OR = 3.889, 95% CI = 1.030-14.680. As neither group offers any significant benefit from preterm delivery, multiple pregnancies continue to be responsible for preterm delivery despite fetal reduction. CONCLUSION: There appears to be some advantages of MFPR in perinatal outcome when compared to SFR, especially if the latter happens at advanced gestation. Therefore, although it is advisable to wait for SFR to occur, in patients with triplet gestation at 11-12 weeks, MFPR is a viable option to be considered.

Full Text Available MMPs play an important role in human reproduction, because in the early stages of embryogenesis the degradation and remodeling of extracellular matrix are the key processes. Only known function for MMP20 is dental enamel formation. But the data about its role in spontaneous abortion is very poor. Thus, the aim of this study was to investigate the association of Val275Ala (rs1784423 and A320C (rs2245803 polymorphisms MMP20 gene with pregnancy loss in the first trimester in women, and MMP20 gene expression analysis in decidua and chorionic tissues. A total of 132 women with spontaneous abortion in the first trimester and 144 control patients were examined by a case-control methodology. Samples of chorionic tissue and decidua were taken after surgical termination of normally progressing pregnancies in 5-9 week of gestation (n=12 and spontaneous abortion in 5-9 week of gestation (n=12. Our investigation have not detected association of gene polymorphisms MMP20 Val275Ala (rs1784423 and A320C (rs2245803 with miscarriage in the first trimester. Compared with chorionic tissue, the MMP20 expression was increased in decidua in both groups (p = 0.0037, P = 0.014 respectively. The results demonstrated the tissue-specific MMP20 expression in normal pregnancy and spontaneous abortion.

The risk of relapse of depression or the diagnosis of some other psychiatric disorders during pregnancy necessitates the use of antidepressants despite possible adverse effects. Whether such use increases the risk of spontaneous abortion is still being debated. We evaluated the risk of spontaneous abortion in relation to the use of antidepressants during pregnancy. Using a nested case-control study design, we obtained data from the Quebec Pregnancy Registry for 5124 women who had a clinically detected spontaneous abortion. For each case, we randomly selected 10 controls from the remaining women in the registry who were matched by the case's index date (date of spontaneous abortion) and gestational age at the time of spontaneous abortion. Use of antidepressants was defined by filled prescriptions and was compared with nonuse. We also studied the classes, types and doses of antidepressants. A total of 284 (5.5%) of the women who had a spontaneous abortion had at least one prescription for an antidepressant filled during the pregnancy, as compared with 1401 (2.7%) of the matched controls (odds ratio [OR] 2.09, 95% confidence interval [CI] 1.83-2.38). After adjustment for potential confounders, we found that the use of antidepressants during pregnancy was associated with an increased risk of spontaneous abortion (OR 1.68, 95%CI 1.38-2.06). Stratified analyses showed that use of selective serotonin reuptake inhibitors alone (OR 1.61, 95% CI 1.28-2.04), serotonin-norepinephrine reuptake inhibitors alone (OR 2.11, 95% CI 1.34-3.30) and combined use of antidepressants from different classes (OR 3.51, 95% CI 2.20-5.61) were associated with an increased risk of spontaneous abortion. When we looked at antidepressant use by type versus no use, paroxetine use alone (OR 1.75, 95% CI 1.31-2.34) and venlafaxine use alone (OR 2.11, 95% CI 1.34-3.30) were associated with an increased risk of spontaneous abortion.

The majority of bariatric surgical procedures are performed in young women. There is a concern about safety and outcomes of pregnancies after weight loss surgery. Pregnancy after weight loss surgery is not only safe, but is associated with more favorable outcomes in comparison to obese populations who do not undergo weight loss surgery. An interval of 2 years is recommended from surgery to pregnancy. This delay helps avoid most of the potential nutritional complications. Optimal patient care is achieved in an experienced, multidisciplinary center. Early involvement of the bariatric surgeon in evaluating abdominal pain is critical because the underlying pathology may relate to the previous weight loss surgery. Although infertility is improved after weight loss surgery, reliable modes of contraception may be limited in this population.
Uterine rupture is one of the most feared obstetric complications affecting the pregnant woman and fetus. It is an obstetric dilemma. Most of the cases have various risk factors and mainly occur during the third trimester. However, spontaneous uterine rupture during the first and second trimester are extremely rare.

Vaginal candidiasis is common during pregnancy. Although intravaginal formulations of topical azole antifungals are first-line treatment for pregnant women, oral fluconazole is often used despite limited safety information. To study the association between oral fluconazole exposure during pregnancy and the risk of spontaneous abortion and stillbirth. Nationwide register-based cohort study in Denmark, 1997-2013. From a cohort of 1,405,663 pregnancies, oral fluconazole-exposed pregnancies were compared with up to 4 unexposed pregnancies matched on propensity score, maternal age, calendar year, and gestational age (based on gestational age at first day of treatment with eligible controls surviving through this date). To test for confounding by indication, pregnancies exposed to intravaginal formulations of topical azoles were used as an additional comparator group. Filled prescriptions for oral fluconazole were obtained from the National Prescription Register. Hazard ratios (HRs) for spontaneous abortion and stillbirth, estimated using proportional hazards regression. Among 3315 women exposed to oral fluconazole from 7 through 22 weeks' gestation, 147 experienced a spontaneous abortion, compared with 563 among 13,246 unexposed matched women. There was a significantly increased risk of spontaneous abortion associated with fluconazole exposure (HR, 1.48; 95% CI, 1.23-1.77). Among 5382 women exposed to fluconazole from gestational week 7 to birth, 21 experienced a stillbirth, compared with 77 among 21,506 unexposed matched women. There was no significant association between fluconazole exposure and stillbirth (HR, 1.32 [95% CI, 0.82-2.14]). Using topical azole exposure as the comparison, 130 of 2823 women exposed to fluconazole vs 118 of 2823 exposed to topical azoles had a spontaneous abortion (HR, 1.62 [95% CI, 1.26-2.07]); 20 of 4301 women exposed to fluconazole vs 22 of 4301 exposed to topical azoles had a stillbirth (HR, 1.18 [95% CI, 0.64-2.16]).

Full Text Available Hyperreactio Luteinalis (HL is a benign self-limited pregnancy-related condition characterized by bilateral ovarian enlargement with multiple theca lutein cysts. It is commonly associated with gestational trophoblastic diseases and multiple pregnancy. We report a rare case of HL discovered accidentally during cesarean section (CS of a spontaneously conceived normal singleton pregnancy. CS was performed due to fetal malpresentation and previously scarred uterus, and delivered a healthy male neonate. Expectant management was performed to permit conservation of both ovaries without unnecessary surgical intervention. The condition resolved within 6 weeks postpartum without adding morbidity to the patient.

Background: The study was done to compare the early pregnancy loss rate in women with polycystic ovarian syndrome who received or did not receive metformin in pregnancy. Study type, settings and duration: A case control interventional study carried out at Civil Hospital Karachi, Hamdard University Hospital and Private Gynaecology clinics from January 2005 to July 2008. Subjects and Methods Eighty two non diabetic patients with polycystic ovarian syndrome who became pregnant were included in the study. A questionnaire was filled for all patients that included information on basic demography and mean age, parity, weight. Fasting blood sugar and serum insulin levels were done for all these women. Only patients with raised insulin levels (more than 10 mu/l) were included in the study and all were offered to use oral metformin throughout pregnancy as 500 mg three times a day with folic acid supplements 5 mg once daily. Those who agreed to take the drug throughout pregnancy and to comply with the therapy were taken as cases, while those who did not agree to take the medicine acted as controls. Patients with other causes of recurrent pregnancy loss were excluded from the study. All pregnancies were followed using serial ultrasound examination to see any pregnancy loss in the two groups. Eighty two cases of polycystic ovaries with pregnancy were seen during the study period. All cases had raised serum insulin levels. Fifty patients agreed to take metformin through out pregnancy while, 32 cases did not agree to take metformin during pregnancy and thus acted as controls. The two groups did not differ in mean age, parity, weight and mean fasting blood sugar levels. Fasting insulin levels were high in metformin group (18.40 mu/l ) than in controls (12.53 mu/l). Missed abortion rate was significantly lower (12%) in metformin group than in controls (28%) (p<0.028). No congenital anomalies were found in both the groups on ultrasound at 16-19 weeks.

The pathogenesis of Listeria monocytogenes depends on the ability of this bacterium to escape from the phagosome of the host cells via the action of the pore-forming toxin listeriolysin O (LLO). Expression of the LLO-encoding gene ( hly ) requires the transcriptional activator PrfA, and both hly and prfA genes are essential for L. monocytogenes virulence. Here, we used the hemolytic activity of LLO as a phenotypic marker to screen for spontaneous virulence-attenuating mutations in L. monocytogenes Sixty nonhemolytic isolates were identified among a collection of 57,820 confirmed L. monocytogenes strains isolated from a variety of sources (0.1%). In most cases (56/60; 93.3%), the nonhemolytic phenotype resulted from nonsense, missense, or frameshift mutations in prfA Five strains carried hly mutations leading to a single amino acid substitution (G299V) or a premature stop codon causing strong virulence attenuation in mice. In one strain, both hly and gshF (encoding a glutathione synthase required for full PrfA activity) were missing due to genomic rearrangements likely caused by a transposable element. The PrfA/LLO loss-of-function (PrfA - /LLO - ) mutants belonged to phylogenetically diverse clades of L. monocytogenes , and most were identified among nonclinical strains (57/60). Consistent with the rare occurrence of loss-of-virulence mutations, we show that prfA and hly are under purifying selection. Although occurring at a low frequency, PrfA - /LLO - mutational events in L. monocytogenes lead to niche restriction and open an evolutionary path for obligate saprophytism in this facultative intracellular pathogen.

The results of this study confirm the complexity of the early pregnancy loss etiopatogenesis. Further research need to be conducted in order to identify the non-somatic causative agents of various clinical forms of miscarriage. It may help do select women in reproductive age at high risk of early pregnancy loss and show the ways in which effective preventive measures can be introduced in such population.

The aim of this study was to assess, using the Perinatal Grief Scale (PGS), whether the type of early pregnancy loss influences the severity of grief and whether the presence of living children influences the severity of grief. Over a period of 6 months in 2008, seventy five patients were recruited for the study, of which 7 (9.3%) had molar pregnancies, 20 (26.7%) had ectopic pregnancies, 43 (573%) had a miscarriage and 5 (6.7%) had recurrent miscarriages. In this study there was no significant difference in severity of grief, between women that had a miscarriage and ectopic pregnancy (p = 0.14) or, between women that had a miscarriage and a molar pregnancy (p = 0.85). Women who had experienced a ectopic pregnancy did not have a higher grief intensity than the women that had a molar pregnancy (p = 0.75). However, for women with a child, the grief intensity significantly increases with the number of miscarriages (p = 0.015). Women with no children with an ectopic pregnancy grieve significantly more than those with a child (p = 0.019). An appointment for the \\'Miscarriage Clinic\\' should be offered to all of these women but special attention should be paid to those in the categories most at risk

To assess the effectiveness of luteal start vaginal micronized P in a recurrent pregnancy loss (RPL) cohort. Observational cohort study using prospectively collected data. Not applicable. Women seen between 2004 and 2012 with a history of two or more unexplained pregnancy losses pregnancy(ies). Women were excluded if concomitant findings, such as endometritis, maturation delay, or glandular-stromal dyssynchrony, were identified on EB. Vaginal micronized P was prescribed at a dose of 100-200 mg every 12 hours starting 3 days after LH surge (luteal start) if glandular epithelial nuclear cyclin E (nCyclinE) expression was elevated (>20%) in endometrial glands or empirically despite normal nCyclinE (≤20%). Women with normal nCyclinE (≤20%) who did not receive P were used as controls. Pregnancy success was an ongoing pregnancy >10 weeks in size. One hundred sixteen women met the inclusion criteria, of whom 51% (n = 59) had elevated nCyclinE and 49% (n = 57) had normal nCyclinE. Pregnancy success in the 59 women with elevated nCyclinE significantly improved after intervention: 6% (16/255) in prior pregnancies versus 69% (57/83) in subsequent pregnancies. Pregnancy success in subsequent pregnancies was higher in women prescribed vaginal micronized P compared with controls: 68% (86/126) versus 51% (19/37); odds ratio = 2.1 (95% confidence interval, 1.0-4.4). In this study, we found that the use of luteal start vaginal micronized P was associated with improved pregnancy success in a strictly defined cohort of women with RPL.

Full Text Available Context: Blastocyst stage embryo transfer (ET has become routine practice in recent years. However, probably due to limitations of assisted hatching techniques, expanded blastocyst transfer (EBT is still the preferred mode. Inexplicably, not much consideration has been given to spontaneously hatching/hatched blastocyst transfer (SHBT. Aim: This study aimed to investigate developmental potential of spontaneously hatching/hatched blastocyst against EBT in in vitro fertilization (IVF cycles. Settings and Design: Prospective study of 146 women undergoing their first IVF- ET cycle. SUBJECTS AND Methods: On the basis of blastocyst status, women were classified into SHBT and EBT groups. Intracytoplasmic sperm injection cycles were excluded to remove male factor bias. Implantation rate (IR, clinical pregnancy rate, and live birth rate were the main outcome measures. Statistical Analysis: Graph-pad Prism 5 statistical package. Results: SHBT group showed significantly higher blastocyst formation rate (53.3 ± 17.5 vs. 43.1 ± 14.5%, P = 0.0098, top-quality blastocysts (71.8 vs. 53.7%, P = 0.0436, IR (43.6 vs. 27.9%, P = 0.0408, pregnancy rate (59.4 vs. 45.1%, P = 0.0173, and live birth rate (36.8 vs. 22.8%, P = 0.003 compared to EBT group. Multiple pregnancy rates remained comparable between the two groups. Implantation correlated strongly with top-quality blastocysts (Pearson, r = 0.4441 in SHBT group, while the correlation was nonsignificant in EBT group. Conclusion: Extending culture of expanded blastocysts by a few hours to allow transfer of spontaneously hatching/hatched blastocysts gives higher implantation and pregnancy rates with no added risk of multiple gestations. Spontaneously hatching/hatched blastocysts have a better potential to implant and develop into a positive pregnancy.

Pregnancy malaria (PM) is associated with a proinflammatory immune response characterized by increased levels of cytokines and chemokines such as tumor necrosis factor-α, interferon-γ, interleukin 10 (IL-10), and CXCL9. These changes are associated with poor outcomes including low birthweight delivery and maternal anemia. However, it is unknown if inflammatory pathways during malaria are related to pregnancy loss and preterm delivery (PTD). Cytokine and chemokine levels were measured in maternal peripheral blood at enrollment, gestational week 30-32, and delivery, and in placental blood, of 638 women during a longitudinal cohort study in Ouelessebougou, Mali. Plasmodium falciparum infection was assessed by blood smear microscopy at all visits. PM was associated with increased levels of cytokines and chemokines including IL-10 and CXCL9. In a competing risks model adjusted for known covariates, high CXCL9 levels measured in the peripheral blood during pregnancy were associated with increased risk of pregnancy loss and PTD. At delivery, high IL-10 levels in maternal blood were associated with an increase in pregnancy loss, and increased IL-1β levels in placental blood were associated with pregnancy loss and PTD. PM is associated with increased proinflammatory cytokine and chemokine levels in placental and maternal peripheral blood. Systemic inflammatory responses to malaria during pregnancy predict increased risk of pregnancy loss and PTD. NCT01168271.

Full Text Available Purpose of the Review: Thyroid disturbances are common in women during their reproductive years. Thyroid dysfunction interferes with human reproductive physiology, reduces the likelihood of pregnancy and adversely affects pregnancy outcome, thus becoming relevant in the algorithm of reproductive dysfunction. This review highlights the "gap" in knowledge regarding the contribution of thyroid dysfunction in reproduction. Literature Reviewed: Following implantation, the maintenance of the pregnancy is dependent on a multitude of endocrinological events that will eventually aid in the successful growth and development of the fetus. It is estimated that approximately 8-12% of all pregnancy losses are the result of endocrine factors. Autoimmune thyroid disease is present in around 4% of young females and up to 15% are at risk because they are thyroid antibody-positive. There is a strong relationship between thyroid immunity on one hand and infertility, miscarriage, and thyroid disturbances in pregnancy and postpartum, on the other hand. Even minimal hypothyroidism can increase rates of miscarriage and fetal death and may also have adverse effects on later cognitive development of the offspring. Hyperthyroidism during pregnancy may also have adverse consequences. Summary: Pregnant women with subclinical hypothyroidism or thyroid antibodies have an increased risk of complications, especially pre-eclampsia, perinatal mortality, and miscarriage. Universal screening for thyroid hormone abnormalities is not routinely recommended at present, but thyroid function must be examined in female with fetal loss or menstrual disturbances. Practitioners providing health care for women should be alert to thyroid disorders as an underlying etiology for recurrent pregnancy loss.
Full Text Available Uterine artery embolization has emerged as an effective treatment for symptomatic uterine fibroids. Nevertheless because of the uncertainty about the effects of UAE on fertility, women who still want to become pregnant are sometimes excluded from treatment. Pregnancy after UAE has been described in the published literature in the form of case reports, case series and retrospective cohort studies. We present an interesting case of a successful spontaneous pregnancy and delivery in a 42year old woman, who was diagnosed to have fibroids and endometriosis. She had a myomectomy followed by two procedures of UAE for recurrent fibroids and was treated for extensive endometriosis.
Full Text Available Background: Premature ovarian failure (POF is a common condition; its incidence is estimated to be as great as 1 in 100 by the age of 40 years. Physiologic replacement of ovarian steroid hormones seems rational until the age of normal menopause. Temporary return of ovarian function and pregnancy may occur rarely in women with POF. We report a case of POF who conceived during hormone replacement therapy.Case: A 30 years-old woman with confirmed POF after pelvic surgery and sever emotional stress conceived spontaneously.Conclusion: Return of ovarian function and achievement of pregnancy is possible in women with POF.

Spontaneous liver rupture during pregnancy is extremely rare, and often associated with hypertensive disorders. Maternal outcomes are poor and morbidity is high. A 27-year-old women (G1P0), pregnant with monochorionic-monoamniotic twins, developed extensive abdominal pain while she was electively admitted at 32 weeks for fetal pulmonary maturation. Diagnosed with preterm labor, a caesarean section was performed. Postoperatively, our patient deteriorated and a second laparotomy revealed an extensive liver rupture. There was no evidence of hypertensive disorders or hepatic tumors. After perihepatic packing and embolization, our patient required long-term treatment in our intensive care unit. She survived, and both mother and children are healthy after 6 months. Despite being rare, spontaneous liver rupture in absence of hypertensive disorders during pregnancy is associated with high maternal morbidity and mortality. Adequate treatment requires a multidisciplinary approach. Copyright (c) 2010 S. Karger AG, Basel.

Since the first study was published reporting the candidate association between the prolactin receptor gene intron C/T polymorphism (rs37389) and recurrent miscarriage, no replication study has been performed. In this study, we investigated the role of the prolactin receptor gene C/T polymorphism in 311 Korean women with recurrent pregnancy loss and 314 controls. Genotyping for prolactin receptor gene intron C/T polymorphism was performed using a TaqMan assay. The significance of difference in the genotype distribution was assessed using a chi-square test, and continuous variables were compared using a Student's t-test. The genotype distribution of the prolactin receptor gene C/T polymorphism in the recurrent pregnancy loss group did not differ from that in the control group (CC/CT/TT rates were 49.8%/41.5%/8.7% and 52.5%/37.6%/9.9% for the recurrent pregnancy loss patient and control groups, respectively, p = .587). When the analysis was restricted to patients with three or more consecutive spontaneous miscarriages or patients without prior live birth, there were also no differences in the genotype distribution between these subgroups and controls. In conclusion, the findings of the current study suggest that the prolactin receptor gene intron C/T polymorphism is not a major determinant of the development of recurrent pregnancy loss. Impact statement What is already known: Many studies have investigated whether there is a genetic component for the risk of recurrent pregnancy loss. Recently, one study investigated whether genetic polymorphisms involved in the regulation of the hypothalamic-pituitary-ovarian axis would be associated with recurrent miscarriage. Among 35 polymorphisms in 20 candidate genes, genotype distribution with regard to the prolactin receptor gene intron C/T polymorphism (rs37389) differed between the recurrent miscarriage and the control groups. Since this study reporting the candidate association between the prolactin receptor gene and

The cause of recurrent pregnancy loss often remains unknown. Possibly, pathophysiological pathways are shared with other pregnancy complications. All women with secondary recurrent pregnancy loss (SRPL) visiting Leiden University Medical Center (January 2000-2015) were included in this retrospective cohort to assess whether women with SRPL have a more complicated first pregnancy compared with control women. SRPL was defined as three or more consecutive pregnancy losses before 22 weeks of gestation, with a previous birth. The control group consisted of all Dutch nullipara delivering a singleton (January 2000-2015). Information was obtained from the Dutch Perinatal Registry. Outcomes were preeclampsia, preterm birth, post-term birth, intrauterine growth restriction, breach position, induction of labor, cesarean section, congenital abnormalities, perinatal death and severe hemorrhage in the first ongoing pregnancy. Subgroup analyses were performed for women with idiopathic SRPL and for women ≤35 years. In all, 172 women with SRPL and 1 196 178 control women were included. Women with SRPL were older and had a higher body mass index; 29.7 years vs. 28.8 years and 25.1 kg/m 2 vs. 24.1 kg/m 2 , respectively. Women with SRPL more often had a post-term birth (OR 1.86, 95% CI 1.10-3.17) and more perinatal deaths occurred in women with SRPL compared with the control group (OR 5.03, 95% CI 2.48-10.2). Similar results were found in both subgroup analyses. The first ongoing pregnancy of women with (idiopathic) SRPL is more often complicated by post-term birth and perinatal death. Revealing possible links between SRPL and these pregnancy complications might lead to a better understanding of underlying pathophysiology. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

To determine the impact of a history of spontaneous abortion on pre-eclampsia during a subsequent pregnancy. A cross-sectional study enrolled pregnant women admitted to obstetrics and gynecology wards at 103 hospitals in Tehran, Iran for delivery between July 6 and July 21, 2015. Consenting participants were interviewed by midwives; data were collected using a five-part questionnaire and patients' medical records were retrieved. Patient data were analyzed by multiple logistic regression to identify variables associated with increased odds of pre-eclampsia. In total, 5170 patients were interviewed and 252 had experienced pre-eclampsia. The number of previous spontaneous abortions was found to be associated with pre-eclampsia, and a higher number of previous spontaneous abortions was associated with increased odds of patients having experienced pre-eclampsia (adjusted odds ratio 1.28, 95% confidence interval 1.03-1.59; P=0.025). A history of spontaneous abortion was associated with increased odds of pre-eclampsia during a subsequent pregnancy. © 2016 International Federation of Gynecology and Obstetrics.

Despite having one of the most liberal abortion laws in sub-Saharan Africa, complications from induced abortion are the second leading cause of maternal mortality in Ghana. The sample is composed of patients with pregnancy termination complications in Ghana between June and July 2008. The majority of patients report having had a spontaneous abortion (75%; n=439), while 17% (n=100) and 8% (n=46) report having had an induced abortion or an ectopic pregnancy, respectively. Factors associated with women in each of the three groups were explored using multinomial logistic regression. When compared to women with spontaneous abortions, women with induced abortions were younger, poorer, more likely to report no religious affiliation, less likely to be married, more likely to report making the household decisions and more likely to fail to disclose this pregnancy to their partners. Within the induced abortion subsample, failure to disclose the most recent pregnancy was associated with already having children and autonomous household decision making. Identifying the individual and relationship characteristics of induced abortion patients is the first step toward targeted policies and programs aimed at reducing unsafe abortion in Ghana.

To show whether a clinically significant difference in success rates exists between expectant and surgical management of early pregnancy loss. Randomised controlled trial comparing expectant versus surgical management of early pregnancy loss over a 1-year period from 1st January to 31st December 2009 at Sultanah Aminah Hospital, Johor Bahru. Pregnant women with missed or incomplete miscarriages at gestations up to 14 weeks were recruited in this study. The success rate in the surgical group was measured as curettage performed without any complications during or after the procedure, while the success rate in the expectant group was defined as complete spontaneous expulsion of products of conception within 6 weeks without any complication. A total of 360 women were recruited and randomised to expectant or surgical management, with 180 women in each group. There was no statistically significant difference in the success rate between the groups and between the different types of miscarriage. With expectant management, 131 (74%) patients had a complete spontaneous expulsion of products of conception, of whom 106 (83%) women miscarried within 7 days. However, the rates of unplanned admissions (18.1%) and unplanned surgical evacuations (17.5%) in the expectant group were significantly higher than the rates (7.4% and 8% respectively) in the surgical group. The complications in both groups were similar. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

This study was conducted to critically evaluate weekly and monthly circulating concentrations of immunoreactive relaxin throughout pregnancies that resulted in live births, stillbirths, and abortions in aquarium-based bottlenose dolphins. A relaxin RIA was used to analyze serum collected during 74 pregnancies involving 41 dolphins and 8 estrous cycles as well as 8 non-pregnant dolphins. Pregnancies resulted in live births (n=60), stillbirths (n=7), or abortions (n=7). Relative to parturition (Month 0), monthly changes (Pdolphins (status-by-week interaction, P=0.59). Status-by-month interaction (Pdolphins with live births, stillbirths, and abortions except concentrations were lower (Pdolphins with stillbirths but not in dolphins with abortions. In conclusion, this study provided new information on the pregnancy-specific nature of relaxin, critical evaluation of the fundamental characteristics of relaxin during pregnancy and pregnancy loss, and clarification on the strengths and limitations of relaxin as a diagnostic aid to determine pregnancy status and assess maternal-fetal health in bottlenose dolphins.

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

To determine the frequency of clinically significant chromosomal abnormalities identified by chromosomal microarray in pregnancy losses at any gestational age and to compare microarray performance with that of traditional cytogenetic analysis when testing pregnancy losses. Among 535 fetal demise specimens of any gestational age, clinical microarray-based comparative genomic hybridization (aCGH) was performed successfully on 515, and a subset of 107 specimens underwent additional single nucleotide polymorphism (SNP) analysis. Overall, clinically significant abnormalities were identified in 12.8% (64/499) of specimens referred with normal or unknown karyotypes. Detection rates were significantly higher with earlier gestational age. In the subset with normal karyotype, clinically significant abnormalities were identified in 6.9% (20/288). This detection rate did not vary significantly with gestational age, suggesting that, unlike aneuploidy, the contribution of submicroscopic chromosomal abnormalities to fetal demise does not vary with gestational age. In the 107 specimens that underwent aCGH and SNP analysis, seven cases (6.5%) had abnormalities of potential clinical significance detected by the SNP component, including female triploidy. aCGH failed to yield fetal results in 8.3%, which is an improvement over traditional cytogenetic analysis of fetal demise specimens. Both the provision of results in cases in which karyotype fails and the detection of abnormalities in the presence of a normal karyotype demonstrate the increased diagnostic utility of microarray in pregnancy loss. Thus, chromosomal microarray testing is a preferable, robust method of analyzing cases of pregnancy loss to better delineate possible genetic etiologies, regardless of gestational age.

Studies on fertility in Africa have known a major paradigm shift when demographic concerns about ‘overpopulation’ came to be replaced by new ideas about reproductive health, rights, and choices during the 1994 International Conference on Population and Development (ICPD). Whereas this shift has allowed for more recognition of losses during pregnancy which had been virtually absent in previous demographic accounts of high fertility rates, the new discourse on rights and choices turns most of i...

BACKGROUND: Consumption of caffeine and alcohol is suspected to affect pregnancy outcome. Use of both stimulants is widespread and even minor effects on fetal viability are of public health interest. METHODS: We performed a nested case-control study using prospective data from a population......-based cohort comprising 11088 women aged 20-29 years. From this cohort, women who experienced either a spontaneous abortion (n = 303) or who gave birth (n = 1381) during follow-up [mean time: 2.1 years (range: 1.6-3.4)] were selected. Associations between self-reported exposures to caffeine and/or alcohol...... at enrolment and spontaneous abortion were analysed by means of logistic regression. RESULTS: Compared with women with a pre-pregnancy intake of caffeine per day, the adjusted odds ratio (95% confidence interval) for spontaneous abortion was 1.26 (0.77-2.06), 1.45 (0.87-2.41), 1.44 (0.87-2.37) and 1...

To determine whether use of antiepileptic drugs during pregnancy may increase the risk of spontaneous abortion or stillbirth. Population based cohort study. Register based study in Denmark, 1997-2008. 983,305 pregnancies identified in the Danish medical birth register and the Danish national hospital discharge register from 1 February 1997 to 31 December 2008 were linked to the Danish Register of Medicinal Product Statistics to obtain information on use of antiepileptic drugs. Risk ratio of spontaneous abortion and stillbirth after use of antiepileptic drugs during pregnancy, estimated by using binomial regression adjusting for potential confounders of maternal age, cohabitation, income, education, history of severe mental disorder, and history of drug misuse. Antiepileptic drugs were used in a total of 4700 (0.5%) pregnancies. 16 out of 100 pregnant women using antiepileptics and 13 out of 100 pregnant women not using antiepileptics experienced a spontaneous abortion. After adjusting for potential confounders pregnant women using antiepileptics had a 13% higher risk of spontaneous abortions than pregnant women not using antiepileptics (adjusted risk ratio 1.13, 95% confidence interval 1.04 to 1.24). However, the risk of spontaneous abortion was not increased in women with an epilepsy diagnosis (0.98, 0.87 to 1.09), only in women without a diagnosis of epilepsy (1.30, 1.14 to 1.49). In an analysis including women with at least two pregnancies with discordant antiepileptic drug use (for example, use in the first pregnancy but not in the second), the adjusted hazard ratio for spontaneous abortion was 0.83 (0.69 to 1.00) for exposed pregnancies compared with unexposed pregnancies. Stillbirth was identified in 18 women who used antiepileptic drugs (unadjusted risk ratio 1.29, 0.80 to 2.10). Among women with epilepsy and when analysing the risk in antiepileptic drug discordant pregnancies in the same woman, we found no overall association between the use of

Choledochal cysts are a congenital disorder of the bile duct, usually presenting in childhood. As they cause weakening of the wall of the bile duct, any distal obstruction, infection or reflux of amylase-rich fluid in the biliary tract can predispose to spontaneous perforation. A 25-year-old pregnant woman at 35 weeks of gestation presented with acute abdominal and fetal distress. On emergency laparotomy, common bile duct perforations were detected. T-tube drainage and caesarean section were performed. A t-tube cholangiogram revealed the diagnosis of a choledochal cyst with an abnormal pancreatobiliary junction and chronic pancreatitis. The patient later underwent cyst excision with Roux en Y hepaticojejunostomy. Spontaneous choledochal cyst perforation in pregnancy can be successfully managed by a two-stage operation. 2014 BMJ Publishing Group Ltd.

Animal studies demonstrate that several phthalates are embryofetotoxic and are associated with increased pregnancy loss and malformations. Results from human studies on phthalates and pregnancy loss are inconsistent. We examined pregnancy loss prospectively in relation to urinary phthalate metabolite concentrations among women undergoing medically assisted reproduction. We used data from 256 women conceiving 303 pregnancies recruited between 2004 and 2012 from the Massachusetts General Hospital Fertility Center. We quantified 11 phthalate metabolite concentrations and calculated the molar sum of four di(2-ethylhexyl) phthalate (DEHP) metabolites (ΣDEHP). We estimated risk ratios (RRs) and 95% confidence intervals for biochemical loss and total pregnancy loss (assisted reproduction.

Full Text Available While grief, emotional distress and other mental health conditions have been associated with pregnancy loss, less is known about the mental health impact of these events during subsequent pregnancies and births. This paper examined the impact of any type of pregnancy loss on mental health in a subsequent pregnancy and postpartum. Data were obtained from a sub-sample (N = 584 of the 1973-78 cohort of the Australian Longitudinal Study on Women's Health, a prospective cohort study that has been collecting data since 1996. Pregnancy loss was defined as miscarriage, termination due to medical reasons, ectopic pregnancy and stillbirth. Mental health outcomes included depression, anxiety, stress or distress, sadness or low mood, excessive worry, lack of enjoyment, and feelings of guilt. Demographic factors and mental health history were controlled for in the analysis. Women with a previous pregnancy loss were more likely to experience sadness or low mood (AOR = 1.75, 95% CI: 1.11 to 2.76, p = 0.0162, and excessive worry (AOR = 2.01, 95% CI: 1.24 to 3.24, p = 0.0043 during a subsequent pregnancy, but not during the postpartum phase following a subsequent birth. These results indicate that while women who have experienced a pregnancy loss are a more vulnerable population during a subsequent pregnancy, these deficits are not evident in the postpartum.

While grief, emotional distress and other mental health conditions have been associated with pregnancy loss, less is known about the mental health impact of these events during subsequent pregnancies and births. This paper examined the impact of any type of pregnancy loss on mental health in a subsequent pregnancy and postpartum. Data were obtained from a sub-sample (N = 584) of the 1973-78 cohort of the Australian Longitudinal Study on Women's Health, a prospective cohort study that has been collecting data since 1996. Pregnancy loss was defined as miscarriage, termination due to medical reasons, ectopic pregnancy and stillbirth. Mental health outcomes included depression, anxiety, stress or distress, sadness or low mood, excessive worry, lack of enjoyment, and feelings of guilt. Demographic factors and mental health history were controlled for in the analysis. Women with a previous pregnancy loss were more likely to experience sadness or low mood (AOR = 1.75, 95% CI: 1.11 to 2.76, p = 0.0162), and excessive worry (AOR = 2.01, 95% CI: 1.24 to 3.24, p = 0.0043) during a subsequent pregnancy, but not during the postpartum phase following a subsequent birth. These results indicate that while women who have experienced a pregnancy loss are a more vulnerable population during a subsequent pregnancy, these deficits are not evident in the postpartum.

Health authorities in numerous countries recommend periconceptional folic acid supplementation to prevent neural tube defects. The objective of this study was to examine the association of dietary folate intake and folic acid supplementation during different periods of pregnancy with the risk of spontaneous preterm delivery (PTD). The Norwegian Mother and Child Cohort Study is a population-based prospective cohort study. A total of 66,014 women with singleton pregnancies resulting in live births in 2002-2009 were included. Folic acid supplementation was self-reported from 26 weeks before pregnancy until pregnancy week 24. At gestational week 22, the women completed a food frequency questionnaire, which allowed the calculation of their average total folate intake from foods and supplements for the first 4-5 months of pregnancy. Spontaneous PTD was defined as the spontaneous onset of delivery between weeks 22+0 and 36+6 (n = 1,755). The median total folate intake was 313 μg/d (interquartile range IQR 167-558) in the overall population and 530 μg/d (IQR 355-636) in the supplement users. Eighty-five percent reported any folic acid supplementation from effect of dietary folate intake or folic acid supplementation on spontaneous PTD. Preconceptional folic acid supplementation starting more than 8 weeks before conception was associated with an increased risk of spontaneous PTD. These results require further investigation before discussing an expansion of folic acid supplementation guidelines.

Interstitial implantation in a heterotopic pregnancy is extremely rare, and despite currently available diagnostic modalities, early identification of an interstitial ectopic pregnancy remains difficult. This report describes a case of spontaneous cornual rupture at 26 weeks' gestation in a woman with diamniotic dichorionic twins that resulted in live births. The patient had previously undergone laparoscopic bilateral salpingectomy, and the pregnancy was conceived with in vitro fertilization. Interstitial implantation in a heterotopic pregnancy can go unrecognized, resulting in increased maternal and infant morbidity and mortality. © 2015 Wiley Periodicals, Inc.

Seventy-six female patients with two or more recurrent pregnancy losses (RPL) during the 1st trimester were studied. Based on the results of the aCL and aB2GPI antibodies testing, patients were divided in two groups: 22 patients with RPL and elevated immunoglobulin (Ig) G/IgM aCL and/or aB2GPI [RPL + antiphospholipid syndrome (APS)] and 54 patients with RPL alone (without high antibodies). Immunoglobulin G aPS and IgG a-AnV in patients with RPL + APS were higher than in controls and IgG aPS w...

To evaluate the risk of gestational trophoblastic neoplasia (GTN) after spontaneous human chorionic gonadotropin normalization in postmolar follow-up. Retrospective chart review of 2284 consecutive cases of hydatidiform mole with spontaneous normalization of hCG following uterine evacuation treated at one of five Brazilian reference centers from January 2002 to June 2013. After hCG normalization, GTN occurred in 10/2284 patients (0.4%; 95% CI 0.2%-0.8%). GTN developed in 9/1424 patients (0.6%; 95% CI 0.3%-1.2%) after a complete hydatidiform mole, in 1/849 patients (0.1%; 95% CI<0.01%-0.7%) after a partial hydatidiform mole, and in 0/13 patients (0%; 95% CI 0%-27%) after a twin molar pregnancy. The median time to GTN diagnosis after hCG normalization was 18months, and no diagnoses were made before six months of postmolar surveillance. Patients who required more than 56days to achieve a normal hCG value had a ten-fold increased risk of developing GTN after hCG normalization (9/1074; 0.8%; 95% CI 0.4%-1.6%) compared to those who reached a normal hCG level in fewer than 56days (1/1210;0.08%; 95% CI<0.01%-0.5%; p=0.008). All patients presented with symptoms at the time of GTN diagnosis. GTN after spontaneous hCG normalization following molar pregnancy is exceedingly rare, and the few patients who do develop GTN after achieving a normal hCG value are likely to be diagnosed after completing the commonly recommended six months of postmolar surveillance. Current recommendations for surveillance after hCG normalization should be revisited. Copyright © 2015 Elsevier Inc. All rights reserved.

Thyroid autoimmunity is the most prevalent autoimmune state that affects up to 4% of women during the age of fertility. A growing body of clinical studies links thyroid autoimmunity as a cause of infertility and adverse pregnancy outcomes that includes miscarriage or preterm deliveries. Importantly, these adverse effects are persistent in euthyroid women. In the current review we elaborate on the pathogenesis that underlies infertility and increased pregnancy loss among women with autoimmune thyroid disease. Such mechanisms include thyroid autoantibodies that exert their effect in a TSH-dependent but also in a TSH-independent manner. The later includes quantitative and qualitative changes in the profile of endometrial T cells with reduced secretion of IL-4 and IL-10 along with hypersecretion of interferon-γ. Polyclonal B cells activation is 2-3 time more frequent in thyroid autoimmunity and is associated with increased titers of non-organ specific autoantibodies. Hyperactivity and Increased migration of cytotoxic natural killer cells that alter the immune and hormonal response of the uterus is up to 40% more common in women with thyroid autoimmunity. Lack of vitamin D was suggested as a predisposing factor to autoimmune diseases, and was shown to be reduced in patients with thyroid autoimmunity. In turn, its deficiency is also linked to infertility and pregnancy loss, suggesting a potential interplay with thyroid autoimmunity in the context of infertility. In addition, thyroid autoantibodies were also suggested to alter fertility by targeting zona pellucida, human chorionic gonadotropin receptors and other placental antigens.

There is a need to elucidate what affects the implantation and early pregnancy course in pregnancies conceived with assisted reproductive technology (ART) so that pregnancy rates and outcomes can be improved. Our aim was to determine the role of maternal Helicobacter pylori infection. We did a prospective study of 187 infertile couples undergoing intracytoplasmic sperm injection (ICSI) and segregated those according to underlying infertility etiology. We assessed the status of H. pylori IgG antibodies and anti-CagA IgG antibodies by ELISA assay. All pregnancies were followed for early pregnancy loss (EPL, first 12 weeks). The likelihood of H. pylori infection increased with age (1.01, 95% confidence interval [CI]: 1.0-1.13; P = 0.040) but there was no association with EPL. Women infected with CagA-positive strains were more likely to have EPL (19.39, 95% CI: 1.8-208.4; P = 0.014). Women with tubal factor or ovulatory disorder infertility were more likely to abort early (12.95, 95% CI: 1.28-131.11; P = 0.030, 10.84, 95% CI: 1.47-80.03; P = 0.020, respectively). There was no association between EPL and age, number of embryos formed or transferred, or number of oocytes retrieved. Our findings suggest that infection with CagA-positive H. pylori strains is linked to an increase in women's potential to abort early (possibly through increased release of inflammatory cytokines). In addition, tubal factor and ovulatory disorder infertility are linked to EPL after ICSI due to unknown mechanisms. Proposals to eradicate H. pylori infection prior to ICSI could lead to a decrease in EPL after ART.

The purpose of this study was to quantify spontaneous first trimester miscarriage rates per woman among parous women. A vast amount of data has accumulated regarding miscarriage rates per recognized pregnancy as well as about recurrent miscarriage. This is the second study of miscarriage rates per woman in a parous population and the first study of recurrent and non-recurrent, spontaneous first trimester miscarriage rates per woman in a large parous population. Extraction of the following variables from all delivery room admissions from both Hadassah Medical Centers in Jerusalem Israel, 2004-2014: # of first trimester spontaneous miscarriages, # live births; # living children; age on admission, pre-pregnancy height and weight, any smoking this pregnancy, any alcohol or drug abuse this pregnancy, blood type, history of ectopic pregnancy, history of cesarean surgery (CS) and use of any fertility treatment(s). Among 53,479 different women admitted to labor and delivery ward, 43% of women reported having had 1 or more first trimester spontaneous miscarriages; 27% reported having had one, 10% two, 4% three, 1.3% four, 0.6% five and 0.05% reported having 6-16 spontaneous first trimester miscarriages. 18.5% had one or more first trimester miscarriages before their first live birth. Eighty-one percent of women with 11 or more living children experienced one or more first trimester miscarriages. First trimester miscarriage rates rose with increasing age, increasing parity, after previous ectopic pregnancy, after previous cesarean surgery, with any smoking during pregnancy and pre-pregnancy BMI ≥30. Miscarriages are common among parous women; 43% of parous women report having experienced one or more first trimester spontaneous miscarriages, rising to 81% among women with 11 or more living children. One in every 17 parous women have three or more miscarriages. Depending on her health, nutrition and lifestyle choices, even a 39 year old parous woman with a history of 3 or

To compare and confirm the impact of prepregnancy body mass index on pregnancy outcome in women with a singleton conceived by assisted reproductive technology and spontaneously conceived pregnancy. A sample of 165 and 247 pregnant women with and without assisted reproductive technology were retrospectively recruited from electronic medical charts of C hospital. There were significant differences between the two groups for maternal age, paternal age, length of marriage, prepregnancy body mass index, parity, spontaneous abortion experience, and preterm delivery. A prepregnancy body mass index of ≥25 was associated with higher risk for maternal and neonatal complication in the assisted reproductive technology group. The results indicate that a higher prepregnancy body mass index is associated with increased risks for adverse pregnancy outcomes for women using assisted reproductive technology. So these women need appropriate care to compensate for the risk.
Full Text Available Background: Some evidence has shown a relationship between human cytomegalovirus (CMV infection and pregnancy loss. However, whether recurrent or latent CMV infection or altered immune response to CMV is related to recurrent pregnancy loss (RPL is unclear. We evaluated CMV infection and avidity of antibodies to CMV in women with RPL. Materials and Methods: This case-control study was conducted on 43 women with RPL referred to a clinical immunology out-patient clinic in Isfahan (Iran, and 43 age-matched multiparous women without history of abortion as control subjects. Patients and controls were evaluated for anti-CMV IgG and IgM antibodies and IgG avidity index (AI using the enzyme linked immunosorbent assay method. Student′s t-test and Chi-square test were used to analyze the data. Results: One case (2.3% of positive anti-CMV IgM was detected in each group. Anti-CMV IgG positivity was more frequent in patients than in controls (90.6% vs. 69.8%, P = 0.014, but there was no difference between the two groups in anti-CMV IgG AI (79.4 ± 11.4 vs. 80.1 ± 10.2, P = 0.781. IgG titer was significantly higher in seropositive cases with RPL than seropositive controls (5.18 ± 1.99 vs. 2.00 ± 0.81, P < 0.001. Conclusion: We found that previous exposure to CMV was significantly higher in patients with RPL than the control group. However, no association was found between IgG AI and RPL. Further investigations are needed to find whether latent CMV infection starts an indirect process of autoimmune etiology in RPL or women with RPL have recurrent or reactivation of CMV infection.

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.

Abstract Acute pancreatitis in pregnancy (APIP) poses a serious threat to the mother and her fetus, and might lead to fetal loss including miscarriage and stillbirth in certain patients. We sought to identify possible factors that affect fetal distress and evaluated outcomes of patients with APIP. We retrospectively reviewed clinical records of 54 pregnant women with APIP, who were treated at 2 tertiary clinical centers over a 6-year period. Clinical characteristics including etiology and severity of APIP, fetal monitoring data, and maternofetal outcomes were analyzed. Etiology of APIP included acute biliary pancreatitis (ABP, n = 14), hyperlipidemic pancreatitis (HLP, n = 22), and other etiologies (n = 18). Severity was classified as mild acute pancreatitis (MAP, n = 23), moderately severe acute pancreatitis (MSAP, n = 24), and severe acute pancreatitis (SAP, n = 7). The incidence of preterm delivery, fetal distress, and fetal loss increased with the progression of severity of APIP (P < .05). The severity of HLP was significantly higher than that of ABP and APIP of other etiology (P < .01). HLP was more likely to lead to fetal distress than other APs (P < .01). Only 12 (22.2%) patients had fetal monitoring including non-stress test (NST); 1 case of SAP (14.3%) and 15 cases of MSAP (62.5%) were not transferred to intensive care unit for intensive monitoring. The incidence of fetal distress and fetal loss increased with worsening of APIP severity. HLP tends to result in worse fetal outcomes. The deficiencies of fetal state monitoring, lack of assessment, and management of pregnant women might increase the fetal loss in APIP. PMID:29443736

Thrombophilia might increase the risk of suffering from obstetric complications by adversely affecting the normal placental vascular function. Our aim was to study the distributions of five thrombosis-associated genetic variants: factor V Leiden, prothrombin G20210A, -675 4G/5G PAI-1, 10034C/T gamma fibrinogen and 7872C/T factor XI and the frequencies of the deficiencies of protein C, S and antithrombin in Argentinian patients with recurrent pregnancy loss (RPL) and, therefore, to analyse their association with the risk and timing of RPL and the risk of suffering other vascular obstetric pathologies. We performed a case-control study that included 247 patients with idiopathic RPL (cases), 107 fertile controls and 224 subjects from general population (reference group). Cases were stratified according to the gestational time of the losses (early RPL, n = 89; late losses, n = 158; foetal losses, n = 107) and according to the type of vascular obstetric pathologies. No differences were found in the distribution of the genetic variants among RPL group vs. control/reference group (p >.05). Similarly, no differences were observed in their distributions when analysing RPL patients stratified according to gestational times or vascular obstetric pathologies (p >.05), except for the factor V Leiden carriage in patients with foetal growth retardation vs. controls (11.8%, 4/34 vs. 1.9%, 2/107; p = .04) (OR = 7.11 [1.24-40.93], p = .03). Factor V Leiden might have a significant impact on certain obstetric pathologies such as foetal growth retardation. The genetic variants, 10034C/T gamma fibrinogen and 7872C/T factor XI, associated with thromboembolic disease, would not have an impact on PRE. Copyright © 2018 Elsevier España, S.L.U.

Grief is a normal response after pregnancy loss. Potentially, prolonged periods of grief can have a negative impact on physical or mental health. African-American women experience pregnancy loss at rates that are at least twice the rate of any other racial or ethnic group. However, the research literature on pregnancy loss has failed to include representative samples of African-American women or to explore and describe adequately their unique experiences after pregnancy loss. The purpose of this study was to examine the factors that are related to grief intensity after pregnancy loss (i.e., miscarriage, ectopic pregnancy, or fetal death) among African-American women. The results presented in this paper are components of a larger study in which the grief and coping experiences of African-American women following pregnancy loss were examined, using both quantitative and qualitative analysis. Eighty-six (N = 86) African-American women with a self-reported history ofinvoluntary pregnancy loss were recruited using a variety of culturally sensitive methods. The women completed three instruments: the Perinatal Grief Scale-Short Form (PGS-S), the Women's Role Integration Protocol (WRIP), and a personal profile tool designed specifically for the study. Pearson correlations were computed using pairwise deletion. Four models were tested using hierarchical multiple regression. Age and level of role integration were recurring predictors of the various dimensions of grief as measured by the PGS-S. Being older and reporting more major role satisfaction contributed to having less grief intensity after pregnancy loss. It is proposed that women with a history of pregnancy loss be assessed for residual grieving across their life span. Future explorations should address two main areas: specific interpersonal relations that facilitate grief management and the partners' experiences after pregnancy loss.

Information about the recurrence of spontaneous preterm birth in subsequent twin/singleton pregnancies is scattered. To quantify the risk of recurrence of spontaneous preterm birth in different subtypes of subsequent pregnancies. An electronic literature search in OVID MEDLINE and EMBASE, complemented by PubMed, to find recent studies. Studies comparing the risk of spontaneous preterm birth after a previous preterm and previous term pregnancy. The absolute risk of recurrence with a 95% confidence interval and the absolute risk of preterm birth after a term delivery were calculated. Data from studies were pooled using the Mantel-Haenszel method. We detected 13 relevant studies. The risk of recurrence of preterm birth was significantly increased in all preterm pregnancy subtypes, compared with their term counterparts. Women pregnant with twins after a previous preterm singleton had the highest absolute risk of recurrence (57.0%, 95% CI 51.9-61.9%), and after a previous term singleton their absolute risk was 25% (95% CI 24.3-26.5%). Women pregnant with a singleton after a previous preterm twin pregnancy have an absolute recurrence risk of 10% (95% CI 8.2-12.3%), whereas a singleton pregnancy after delivering a previous twin up to term yields a low absolute risk of only 1.3% (95% CI 0.8-2.2). Women pregnant with a singleton after a previous preterm singleton have an absolute recurrence risk of 20% (95% CI 19.9-20.6). The risk of recurrence of preterm birth is influenced by the singleton/twin order in both pregnancies, and varies between 10% for a singleton after previous preterm twins to 57% for twins after a previous preterm singleton. © 2014 Royal College of Obstetricians and Gynaecologists.

We have observed the inconsistent findings from various studies on twin pregnancy outcomes obtained by assisted reproductive technology and spontaneous conception. In most studies, however, the concrete chorionicity, regarded as a confounding factor for predicting the perinatal outcomes of twin pregnancies, has not been determined. The purpose of this study was to compare obstetric and perinatal outcomes of only the dichorionic twin pregnancies according to the methods of conception: spontaneous and in-vitro fertilization (IVF). The twin pairs with dichorionicity reported from 1995 to 2008 were investigated and we divided them into two groups which consisted of 286 and 134 twins by spontaneous conception and IVF, respectively. Odds ratios for associations between IVF and pregnancy outcomes were analyzed after adjustment for maternal age and parity. There were no risk differences between the two groups regarding the obstetric complications, which include preterm delivery, preterm labor, preterm premature rupture of membranes, preeclampsia, placenta previa, and abruption. Any differences were not shown in the two groups for the risk estimates of perinatal outcomes, such as low birthweight, very low birthweight, small for gestational age, Apgar scores of conception.

Because subclinical hypothyroidism (thyroid-stimulating hormone [TSH] > 4.5 IU/mL) is associated with adverse pregnancy outcome, including early pregnancy loss, TSH is recommended to be titrated to ≤2.5 mIU/L in levothyroxine-treated women before pregnancy. The purpose of this study was to determine whether borderline-subclinical hypothyroidism (borderline-SCH; 2.5 borderline-SCH, and euthyroidism (0.3 ≤ TSH ≤ 2.5 IU/mL). All women had normal serum free thyroxine (T4) and did not receive levothyroxine before or during the subsequent pregnancy. There were no significant differences in age, number of previous pregnancy losses, number of live births, or body mass index between the borderline-SCH (n = 56) and the euthyroid (n = 261) groups, but the rate of ANA positivity differed significantly (53.6% vs 33.7%, respectively; P = 0.005). The subsequent pregnancy rate did not differ between the two groups (55.4%, 31/56 vs 51.3%, 134/261, respectively). The pregnancy loss rate (borderline-SCH than the euthyroid group (29.0%, 9/31 vs 17.9%, 24/134), although not significantly so (P = 0.16). Although some subset of uRPL is though to be due to as-yet-unidentified cause(s), borderline-SCH is unlikely to be involved in uRPL. © 2017 Japan Society of Obstetrics and Gynecology.

Little research in low-income countries has compared the social and cultural ramifications of loss in childbearing, yet the social experience of pregnancy loss and early neonatal death may affect demographers' ability to measure their incidence. Ninety-five qualitative reproductive narratives were collected from 50 women in rural southern Tanzania who had recently suffered infertility, miscarriage, stillbirth or early neonatal death. An additional 31 interviews with new mothers and female elders were used to assess childbearing norms and social consequences of loss in childbearing. We found that like pregnancy, stillbirth and early neonatal death are hidden because they heighten women's vulnerability to social and physical harm, and women's discourse and behaviors are under strong social control. To protect themselves from sorcery, spiritual interference, and gossip--as well as stigma should a spontaneous loss be viewed as an induced abortion--women conceal pregnancies and are advised not to mourn or grieve for "immature" (late-term) losses. Twelve of 30 respondents with pregnancy losses had been accused of inducing an abortion; 3 of these had been subsequently divorced. Incommensurability between Western biomedical and local categories of reproductive loss also complicates measurement of losses. Similar gender inequalities and understandings of pregnancy and reproductive loss in other low-resource settings likely result in underreporting of these losses elsewhere. Cultural, terminological, and methodological factors that contribute to inaccurate measurement of stillbirth and early neonatal death must be considered in designing surveys and other research methods to measure pregnancy, stillbirth, and other sensitive reproductive events.

We sought to present a series of 13 pregnancy-associated spontaneous coronary artery dissection (P-SCAD), their angiographic and multimodal imaging findings, acute phase treatment, and outcomes. Between 2005 and 2015, 13 cases of P-SCAD were collected from a database of 11 tertiary hospitals. The mean age was 33.8 ± 3.7 years; most patients had no risk factors for coronary artery disease, and the majority were multiparous. P-SCAD occurred during the puerperium in 12 patients with a median time of 10 days. Only one patient presented with P-SCAD in the 37th week of pregnancy, and she was the only patient who died in this series. Six patients (46%) presented with ST-segment elevation acute myocardial infarction (STEMI), six (46%) presented with non-STEMI, and one presented with unstable angina; one-third of women had cardiogenic shock. In 12 patients, the dissection involved the left anterior descending or circumflex artery, and it extended to the left main coronary artery in 6 patients. Intravascular ultrasound or optical coherence tomography helped to confirm diagnosis and guide treatment in 46% of cases. Seven women were managed clinically; percutaneous coronary intervention was performed in five cases, and coronary artery bypass grafting was performed in one patient. In these 13 cases of P-SCAD, clinical presentation commonly included acute myocardial infarction and cardiogenic shock. Multivessel dissections and involvement of the left coronary artery and left main coronary artery were highly prevalent. Clinicians must be aware of angiographic appearances of P-SCAD for prompt diagnosis and management in these high-risk patients. Published on behalf of the European Society of Cardiology.

Some spontaneous preterm deliveries (PTD) are caused by occult infections of the fetal membranes (histologic chorioamnionitis [HCA]). High levels of infection-related markers, including some cytokines, sampled from maternal circulation in mid-pregnancy have been linked to PTD, but whether these specifically identify HCA has not been established. We have tested associations between thirteen Th1, Th2 and Th17 cytokines and PTD with and without HCA in a prospective cohort study. The study sample included 926 Pregnancy Outcomes and Community Health Study subcohort women; women with medically indicated PTD or incomplete data excluded. A panel of cytokines was assessed using a multiplex assay in maternal plasma collected at 15–27 weeks of gestation. Severe HCA was scored by a placental pathologist blinded to clinical variables. Multivariable polytomous logistic regression was used to estimate adjusted odds ratios (OR) per 1 standard deviation (SD) increase in cytokine levels using a 5 level outcome variable: PTD <35 weeks with HCA, PTD <35 weeks without HCA, PTD 35–36 weeks with HCA, PTD 35–36 weeks without HCA, and term (referent). Interleukin (IL)-1β, IL-2, IL-12, interferon-γ, IL-4, IL-6 and transforming growth factor-β were all significantly associated with PTD <35 weeks with HCA, with ORs of 1.6 – 2.3 per SD increase. None of these were associated with PTD <35 weeks without HCA or PTD 35–36 weeks with HCA. Although the tissues of origin of circulating cytokines are unclear, the observed elevations across many cytokines among women who later delivered <35 weeks with HCA may represent a robust immune response to infection within gestational tissues. These results suggest that women with HCA could be identified using relatively non-invasive means. PMID:18814919

Preeclampsia (PE), small for gestational age (SGA), and spontaneous preterm birth (PTB) each may be complications of impaired placental function in pregnancy. Although their exact pathogenesis is still unknown, certain infectious agents seem to play a role. Helicobacter pylori (H. pylori) colonization has been associated with increased risk for PE. Our aim was to assess the association between H. pylori colonization and PE, SGA, and PTB. We measured IgG anti-H. pylori and CagA antibodies in serum of pregnant women (median 20.5 weeks, range 16.5-29.4) who participated in a population-based prospective cohort study. Delivery and medical records were assessed. Information on demographics, education, and maternal risk factors was collected by questionnaire. We used multivariate logistic regression analyses to assess associations between H. pylori colonization and PE, SGA, and PTB. In total, 6348 pregnant women were assessed. H. pylori positivity was found in 2915 (46%) women, of whom 1023 (35%) also were CagA-positive. Pregnancy was complicated by PE, SGA, or PTB in 927 (15%) women. H. pylori colonization was associated with PE (aOR 1.51; 95%CI 1.03-2.25). Differentiation according to CagA status revealed the same risk. H. pylori was positively related with SGA, mainly explained by CagA-positive strains (aOR 1.34; 1.04-1.71). No association was observed between H. pylori and PTB. Our data suggest that H. pylori colonization may be a risk factor for PE and SGA. If these associations are confirmed by future studies and shown to be causal, H. pylori eradication may reduce related perinatal morbidity and mortality. © 2016 John Wiley & Sons Ltd.

Recurrent pregnancy loss (RPL) is a multifactorial disorder. The aim of this study was the detection of various genetic polymorphisms and their correlation to RPL, in Greek women. The impact of 12 thrombophilic polymorphisms was evaluated, among 48 Greek women with a history of RPL, vs 27 healthy parous women. Multiplex PCR and in situ hybridization on nitrocellulose films were performed, to investigate 12 genetic polymorphisms previously reported as risk factors for RPL. Heterozygous FV Leiden, homozygous PAI-1 4G/4G, heterozygous MTHFR C677T, homozygous MTHFR A1298C, as much as the combined thrombophilic genotypes MTHFR 677T + ACE Ι/D, MTHFR 677T/1298C + ACE D/D, ACE I/D + b-fibrinogen -455 G/A, FV HR2 + b-fibrinogen -455 G/A showed a correlation as risk factors for RPL, whereas the rest of the investigated polymorphisms and their combinations did not render statistically significant differences between the two groups in study. The results of this study, as well as those of similar studies, concerning the detection of genetic, environmental, and physiological factors underlying RPL, will prove of critical significance in the investigation and treatment of thrombophilic predisposition, in cases of RPL. © 2017 John Wiley & Sons Ltd.

Recurrent pregnancy loss is usually defined as the loss of two or more consecutive pregnancies before 20 weeks of gestation, which occurs in approximately 5% of reproductive-aged women. It has been suggested that women with thrombophilia have an increased risk of pregnancy loss and other adverse pregnancy outcomes. Thrombophilia is an important predisposition to blood clot formation and is considered as a significant risk factor for recurrent pregnancy loss. The inherited predisposition to thrombophilia is most often associated with factor V Leiden mutation, prothrombin G20210A mutation, and methylenetetrahydrofolate reductase C677T and A1298C gene variants. The net effect is an increased cleavage of prothrombin to thrombin and excessive blood coagulation. PMID:26989729

The concept of a carbimazole embryopathy underlies current Endocrine Society advice to avoid this drug in early pregnancy, favouring propylthiouracil as an alternative for the treatment of maternal hyperthyroidism. We aimed to establish whether suspected spontaneous reporting of adverse drug reactions in the UK via the Yellow Card Scheme supports a carbimazole embryopathy and the lack of association between propylthiouracil and congenital anomalies. All birth defects related to maternal treat...

Cardiovascular disease in women often develops without conventional risk factors. Prenatal loss is a common pregnancy outcome that may result in physiological changes can increase the potential future risk of cardiovascular disease. Insufficient information exists regarding the impact of pregnancy loss on early markers of cardiovascular disease risk. Cross-sectional analysis of 1767 disease-free women from the MTC (Mexican Teachers' Cohort) who had been pregnant was used to evaluate the relationship between pregnancy loss and carotid intima-media thickness (IMT). Participants responded to a questionnaire regarding their reproductive history, risk factors, and medical conditions. We defined pregnancy loss as history of miscarriage and/or stillbirth. Trained neurologists measured IMT using ultrasound. We log-transformed IMT and defined subclinical carotid atherosclerosis (SCA) as IMT ≥0.8 mm and/or plaque. We used multivariable linear and logistic regression models to assess the relation of pregnancy loss, IMT, and SCA. The mean age of participants was 49.8±5.1 years. The prevalence of pregnancy loss was 22%, and we observed SCA in 23% of participants. Comparing participants who reported a pregnancy loss and those who did not, the multivariable-adjusted odds ratio for SCA was 1.52 (95% confidence interval, 1.12-2.06). Women who experienced a stillbirth had 2.32 higher odds (95% confidence interval, 1.03-5.21) of SCA than those who did not. Mean IMT appeared to be higher in women who reported a pregnancy loss relative to those who did not; nevertheless, this was not statistically significant. Pregnancy loss could be linked to cardiovascular disease later in life. The key findings of our study await confirmation and further investigation of the potential underlying mechanisms for this association is required. © 2018 The Authors.

In this essay, I interrogate the role time plays in the three most common social support messages I received post-pregnancy loss. In doing so, I illustrate how our most common "social support" responses to pregnancy loss, while uttered from caring, intentional places of support, can actually serve to marginalize and invalidate experiences of pregnancy loss.

Environmental exposure to metals and metalloids is associated with pregnancy loss in some but not all studies. We assessed arsenic, cadmium, mercury, and lead concentrations in 501 couples upon trying for pregnancy and followed them throughout pregnancy to estimate the risk of incident pregnancy loss. Using Cox proportional hazard models, we estimated hazard ratios (HR) and 95% confidence intervals (CIs) for pregnancy loss after covariate adjustment for each partner modeled individually then we jointly modeled both partners' concentrations. Incidence of pregnancy loss was 28%. In individual partner models, the highest adjusted HRs were observed for female and male blood cadmium (HR=1.08; CI 0.81, 1.44; HR=1.09; 95% CI 0.84, 1.41, respectively). In couple based models, neither partner's blood cadmium concentrations were associated with loss (HR=1.01; 95% CI 0.75, 1.37; HR=0.92; CI 0.68, 1.25, respectively). We observed no evidence of a significant relation between metal(loids) at these environmentally relevant concentrations and pregnancy loss. Published by Elsevier Inc.

Context: Prior studies examining associations between subclinical hypothyroidism and antithyroid antibodies with early pregnancy loss and live birth suggest mixed results and time to pregnancy (TTP) has not been studied in this patient population. Objective: This study sought to examine associations of prepregnancy TSH concentrations and thyroid autoimmunity with TTP, pregnancy loss, and live birth among women with proven fecundity and a history of pregnancy loss. Design and Setting: This was a prospective cohort study from a large, randomized controlled trial that took place at four medical centers in the United States. Patients or Other Participants: Healthy women, ages 18–40 y, who were actively attempting to conceive and had one or two prior pregnancy losses and no history of infertility were eligible for the study. Intervention: There were no interventions. Main Outcome Measure: TTP, pregnancy loss, and live birth. Results: Women with TSH ≥ 2.5 mIU/L did not have an increased risk of pregnancy loss (risk ratio, 1.07; 95% confidence interval [CI], 0.81–1.41) or a decrease in live birth rate (risk ratio, 0.97; 95% CI, 0.88–1.07) or TTP (fecundability odds ratio, 1.09; 95% CI, 0.90–1.31) compared with women with TSH pregnancy loss, TSH levels ≥ 2.5 mIU/L or the presence of antithyroid antibodies were not associated with fecundity, pregnancy loss, or live birth. Thus, women with subclinical hypothyroidism or thyroid autoimmunity can be reassured that their chances of conceiving and achieving a live birth are likely unaffected by marginal thyroid dysfunction.

From early pregnancy, maternal hemodynamic profile begins to change. The absence of these changes leads to increased risk of complication during the gestation. Aim of this study is to understand in early pregnancy the behaviour of total vascular resistances (TVR) as a sign of maternal cardiovascular adaptation to pregnancy. A cross section study was conducted. We followed 160 healthy women with singleton pregnancy during the first trimester of gestation. We evaluated cardiac output (CO) and TVR at 7, 9 and 11 weeks of gestation. We obtained the following haemodynamic measurements with the USCOM system, a non invasive method: heart rate (HR), systolic and diastolic blood pressure (SBP, DBP), CO and TVR. 160 healthy pregnant women were selected, 8 patients, were excluded for a bad signal. Absolute values of the haemodynamic measures are shown in Fig. 1. 41 patients underwent spontaneous embryonic demise. This last group of patients showed in 54% (group A) TVR values within the normal limits (TVR1200) and CO values below the normal adaptation to pregnancy. Table 1 shows hemodynamic measures for the group A and group B; we found differences in term of CO, TVR and PAS between the two groups. Elevated TVR might indicate an abnormal vascular adaptation already in first weeks of pregnancy. Moreover, in women who undergo to abortion, elevated TVR could be use to distinguish genetic or environmental causes of miscarriage. Copyright © 2013. Published by Elsevier B.V.

Recurrent pregnancy loss (RPL) is defined as two or more consecutive pregnancy losses before twenty weeks of gestation. It is caused by a variety of genetics and non-genetics factors. Thyroid autoimmunity could associate with pregnancy loss. To investigate the effectiveness of Levothyroxine in treatment of RPL in women with high auto-thyroid antibodies. In this observational cross sectional study, 900 women who had a history of recurrent pregnancy loss were studied. All women with high anti-TPO antibody without any other problems entered in this study. Levothyroxine was given to them two months before pregnancy till the end of pregnancy. The doses of levothyroxine were depended on the anti-TPO levels, which were decided by endocrinologist. Women followed for the results of pregnancies. The success rate of pregnancy in women with abnormal anti-TPO with Levothyroxine therapy was 82.85%. Mean of anti-TPO in women with treatment before taking medication was 488.35 and after that it was 123.35 UI/ml. This difference was significant (pTPO antibody. It decreased anti-TPO antibody levels after 2-3 months treatment.

To evaluate the effectiveness of metformin therapy in reducing early pregnancy loss in pregnant women with polycystic ovary syndrome (PCOS). This is a prospective cohort study conducted in the Obstetric Department of the Gulf Medical College Hospital in Ajman, UAE, for a period of 3 years. This study involved 106 nondiabetic pregnant women with PCOS who became pregnant while using metformin. They were divided into two groups, namely, the group that received metformin throughout pregnancy (metformin group) and the group that discontinued using the drug once pregnancy started (control group). A comparison was made between the two groups of patients with respect to certain basal characteristics (age, body mass index, previous obstetric outcome, serum glucose with free testosterone). Statistical analysis was performed using Chi-square test to compare the differences between the two groups. There were 56 patients who received metformin during pregnancy (metformin group) compared with 50 patients who did not receive the treatment (control group). The rate of early pregnancy loss in the metformin group was 8.9% (5/56) compared with 36% (18/50) in the control group (p metformin group with a history of previous miscarriage, the rate of pregnancy loss was 45% (35 cases/50 pregnancies). Metformin therapy in pregnant women with PCOS was associated with a significant reduction in the rate of early pregnancy loss. Copyright © 2015. Published by Elsevier B.V.

What is the association between daily preconception-initiated low-dose aspirin (LDA) treatment and very early pregnancy losses or euploid (chromosomally normal) losses among women with one to two prior losses? Daily LDA initiated preconception was not associated with the rate or type of pregnancy loss among women with a history of one to two prior pregnancy losses. LDA is often used to treat recurrent pregnancy loss with reductions in pregnancy loss generally only observed among women with antiphospholipid antibodies, and null associations observed among women without antiphospholipid antibodies. We previously evaluated the association between LDA and pregnancy loss overall among women with one to two prior losses in the Effects of Aspirin in Gestation and Reproduction (EAGeR) trial and found no association, though did not distinguish between potential effects at different stages of pregnancy loss, including implantation failure, or between euploid and aneuploid losses. The EAGeR trial was a multi-site prospective block-randomized double-blind placebo-controlled trial. In total, 1228 women were randomized to daily LDA (81 mg/day) plus folic acid (400 mcg/day), or placebo plus folic acid. Participants were assigned study drug for less than or equal to six menstrual cycles or if they conceived, throughout pregnancy with study drug discontinued at 36 weeks gestation. This analysis includes additional outcome information obtained from chart abstractions after the completion of the trial, as well as testing of stored urine for measurement of hCG and detection of very early pregnancy losses, and karyotyping of the products of conception for assessment of aneuploidy of the losses. Women aged 18-40 with a history of one to two prior losses and actively trying to conceive were randomized (n = 615 LDA and n = 613 placebo) at four clinical centers in the USA (2007-2011). Log-binomial regression was used to estimate risk ratios under the intent-to-treat approach. Daily LDA

To determine the association of factor V Leiden mutation with recurrent pregnancy loss. The case-control study was conducted at the Department of Haematology, Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from January to June 2012, and comprised women of 18 to 45 years of age who had a history of recurrent pregnancy loss, and controls with no history of pregnancy loss. All the subjects belonged to Punjabi ethnic group. Three ml blood was taken from cases and controls and deoxyribonucleic acid was extracted. In order to identify Factor V Leiden mutation, polymerase chain reaction method was utilised combined with the amplification refractory mutation system. Data was analysed using SPSS 17. Of the 112 subjects, 56(50%) were in each of the two groups. The presence of factor V Leiden mutation among the cases was 3(5.4%) while it was absent among the controls. The mutation was significantly associated with recurrent pregnancy loss (p=0.017).Recurrent pregnancy loss was higher in cases than controls (p=0.001).

The presence of lupus anticoagulant (LA) predisposes to fetal loss and to venous and arterial thrombosis; however, a subgroup of women is unaffected by pregnancy loss. Currently, no predictive markers are available for the identification of women positive for LA at increased risk for pregnancy loss. It was the aim of our study to investigate whether increased anti-beta2-GPI-antibodies predict pregnancy loss in women positive for LA. We performed a cross-sectional study in a cohort of 39 women with persistent LA, who had in total 111 pregnancies. Fifteen women had exclusively normal pregnancies (30 pregnancies) and 24 women had pregnancy losses (81 pregnancies). Anti-beta2-GPI-antibodies were determined using a semiquantitative enzyme linked immunoassay (QUANTA Lite beta2 GPI IgG and IgM; Inova Diagnostics). Increased levels of anti-beta2-GPI antibodies were significantly associated with pregnancy loss [odds ratio (OR) 9.6, 95% confidence interval (CI) 1.6-56.4]. This risk was even higher in the subgroup of women (n = 16) with more than two miscarriages or fetal loss after the first trimester [OR 13.1, 95% CI 1.4-126.3]. There was no significant association between anticardiolipin antibodies and pregnancy loss [OR 3.5, 95% CI 0.7-17.6]. The co-existence of anti-beta2-GPI and anticardiolipin antibodies was also predictive for pregnancy loss [OR 6.1, 95% CI 1.3-29.7]. Interestingly, the prevalence of thrombosis was similar between women with normal pregnancy (87%) and those with pregnancy loss (75%). We conclude that increased levels of anti-beta2-GPI antibodies are predictive for pregnancy loss among women positive for LA, and that prophylactic treatment should be considered in these women even without a history of previous pregnancy loss.
Environmental and genetic factors are thought to be involved in the pathogenesis of recurrent pregnancy loss (RPL)/spontaneous abortions (SA), which include endocrine, anatomical abnormalities within the genital organs, autoimmune diseases and some gene variants. Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme of the folate/methionine metabolic pathway and it is well established fact that folate deficiency causes pregnancy complications like recurrent pregnancy loss, preeclempsia and birth defects affected pregnancies. MTHFR A1298C polymorphism reduces the enzymatic activity and mimics as folate deficiency. To date, many studies have investigated the association between MTHFR A1298C polymorphism and RPL risk; however, the result is still controversial and inconclusive. The aim of the present study was to address the association of MTHFR A1298C polymorphism with RPL risk by meta—analysis. By searching electronic databases, total seventeen studies were identified for present meta—analysis. Crude odds ratios (OR) with 95 % confidence intervals (CIs) was used to assess the strength of association between A1298C polymorphism and RPL. The results indicate that the A1298C polymorphism is not associated with RPL (ORCvs A = 1.13 ,95 % CI= 0.87—1.46, P = 0.36 ; ORACvs AA = 1.22 ,95 % CI= 0.94— 1.6, P = 0.13; ORCCvsAA =1.35, 95 % CI= 76—2.36, P = 0.30; ORCC+AC vs AA = 1.15, 95 % CI= 88 —1.49, P = 0.29; ORCCvs AC+AA = 1.29, 95 % CI= 76 —2.12, P = 0.34). Further prospective studies were needed to confirm the precise relationship between the MTHFR A1298C polymorphism and RPL.

Cardiac emergencies in pregnancy and the postpartum period are rare but often life-threatening. An emergency physician's differential diagnosis for chest pain in the peripartum patient often includes serious etiologies such as pulmonary embolism or myocardial infarction (MI). A lesser-known but important consideration on the differential for MI is that of a spontaneous coronary artery dissection (SCAD). SCAD is defined as an intramural hematoma within the coronary artery that compresses the true lumen. Expansion by increased pressures may lead to subsequent myocardial ischemia and infarction. This condition is the most common cause of pregnancy-associated MI and is reported as the cause of MI in 24% to 35% of all women younger than 50 years. This condition is predominately seen in young healthy females with no traditional risk factors for coronary artery or cardiac disease, and typically in the postpartum period. SCAD in the peripartum period is defined as pregnancy-associated spontaneous coronary artery dissection (PASCAD). Abnormal ECG changes, elevated troponins, and regional wall motional abnormalities on echocardiography are all diagnostic findings of SCAD, which can be ultimately confirmed with coronary angiography. Failure to immediately address this condition can lead to acute heart failure, cardiogenic shock, and death. Thrombolytic treatment may be harmful and is not recommended, and percutaneous coronary intervention can result in the iatrogenic propagation of further coronary dissection. As a result, the management for suspected SCAD involves emphasis on urgent transfer and urgent coronary artery angiography to determine appropriate treatment modalities.

There are some theoretical concerns for the use of intraoperative cell salvage (ICS) in patients with ectopic pregnancy. This study aimed to observe the impact of ICS on the coagulation function and clinical outcomes of patients with ruptured ectopic pregnancy and severe blood loss. This was a retrospective study of 225 patients with ruptured ectopic pregnancy and severe blood loss treated at the Third Affiliated Hospital of Guangxi Medical University between January 2012 and May 2016. Patients were grouped according to ICS ( n = 116) and controls ( n = 109, allogenic transfusion and no transfusion). Compared with controls, patients with ICS had shorter hospitalization ( P = 0.007), lower requirement for allogenic blood products ( P ectopic pregnancy and severe blood loss.

Does mode of conception [spontaneous/after infertility treatment (IT)], type of pregnancy (singleton/twin) and parent gender have an effect on anxiety and depression levels and trajectories during pregnancy and the post-partum period? Conception after IT was associated with a transitory increase in anxiety during the perinatal period for parents of singletons, while for IT parents of twins higher levels of psychopathological symptoms tended to persist during pregnancy and the post-partum period. Most previous studies have shown that successful IT is not associated with poor psychological well-being during pregnancy and the post-partum period, but there is also some evidence for heightened pregnancy-related anxiety, lower self-esteem and lower self-efficacy. Parents of twins experience increased postnatal anxiety and depression. This prospective longitudinal study assessed 267 couples (N = 534) at each trimester of pregnancy, after childbirth and at 3 months post-partum. The sample comprised 36 couples who had conceived after IT (19 twin pairs and 17 singletons) and 231 couples who had conceived spontaneously (SC; 28 twin pairs and 203 singletons). Couples were recruited at four public hospitals in Portugal, and self-report measures of anxiety and depression symptoms were administered. IT parents reported higher anxiety after childbirth than parents who SC, regardless of pregnancy type. IT parents of twins showed higher anxiety at mid-pregnancy, as well as higher anxiety and depression at 3 months post-partum than IT parents of singletons. Among IT mothers, those who had twins exhibited higher depression after childbirth than those who had singletons. Differences according to mode of conception, pregnancy type and parents gender over time were also noted. During pregnancy, IT parents of twins showed no significant change in depression scores, while the other groups depression scores statistically significantly decreased over time.

Objective: To evaluate the characteristics and spontaneous recovery of tinnitus related to idiopathic sudden sensorineural hearing loss (ISSNHL). Study Design: Retrospective analysis from two randomized placebo-controlled clinical trials for treatment of ISSNHL within 48 hours from onset (Study A), or of tinnitus related to ISSNHL within 3 months from onset (Study B). Setting: Forty-eight European sites (academic tertiary referral centers, private ENT practices). Patients: One hundred thirteen adult patients of which 65 with hearing loss ≥30 dB (Study A) and 48 with persistent acute tinnitus (Study B) at baseline. Interventions: Intratympanic (i.t.) injection of placebo gel in single dose or in triple dose during 3 consecutive days. Main Outcome Measures: Frequency of tinnitus, subjective tinnitus loudness, rates of complete tinnitus remission, and complete hearing recovery during 3 months follow-up. Results: In acute ISSNHL, tinnitus loudness decreased rapidly in cases of mild-moderate hearing loss, and tinnitus had completely resolved in two-thirds of patients after 3 months. Hearing recovery preceded tinnitus resolution. When associated with severe-profound hearing loss, tinnitus improved significantly less. Complete hearing recovery and full tinnitus remission were both about three times more frequent in mild-moderate hearing loss patients than in severe-profound cases. Improvement in tinnitus loudness over time can be approximated by a negative exponential function. Conclusions: Prognosis for ISSNHL-related tinnitus is relatively poor in case of severe-profound hearing loss and the longer it has persisted. Alleviation or management of tinnitus should be a key therapeutic objective especially in pronounced ISSNHL cases. PMID:27228021

In up to 50% of couples affected by recurrent pregnancy loss, no identifiable cause is established. Fetal and maternal factors may be equally important in the establishment and maintenance of the placental/maternal arteriovenous anastomoses. Therefore,the inheritance of thrombophilia-related genes may be an important factor in the pathophysiology of recurrent pregnancy loss. Most of the research on recurrent pregnancy loss and thrombophilia has focused on maternal factors, but little is known about the paternal contribution. On that basis, we studied the association between inherited paternal thrombophilias and recurrent pregnancy loss in a narrowly selective group of 42 Argentine males from couples that presented without any known risk factors for recurrent pregnancy loss. The genotypic distributions of factor (F) V Leiden and prothrombin G20210A among cases were compared with those from a reference group composed of 200 Argentine men. We found a significant difference in the distribution of FV Leiden between both groups (16.7% vs. 3.0%), but no difference was found in the distribution of prothrombin G20210A (2.4% vs.2.0%). Those couples with paternal FV Leiden carriage would be six times more likely to experience recurrent pregnancy loss despite no other apparent cause (OR = 6.47; 95% CI, 2.06–20.39). We found evidence of an association between the paternal carriage of FV Leiden and the predisposition to recurrent pregnancy loss, thereby supporting the hypothesis that genetic contributions from both parents are essential factors in the development of this obstetric disorder.

Background: Hypoglycaemia-associated autonomic failure (HAAF) with impaired neurogenic and neuroglycopaenic responses occurs in adults following recent, repeated hypoglycaemia. Objective and hypotheses: We aimed to evaluate, whether HAAF also occurs in infants with congenital hyperinsulinism (CHI......). Methods: The autonomic, neuroglycopaenic, and glucose counter-regulatory hormonal responses were assessed in a) seven infants with CHI during a controlled fast following initial symptomatic hypoglycaemia and three recent episodes of spontaneous recurrent hypoglycaemia each lasting less than 5 minutes......; and in b) seven infants with ketotic hypoglycaemia for control. Results: When repeated hypoglycaemia was provoked, all CHI patients exhibited a complete loss of hypoglycaemic symptoms and signs, along with a global blunting of the counter-regulatory cortisol, glucagon, growth hormone, epinephrine and nor...
Full Text Available Abstract Background Violence by an intimate partner is increasingly recognized as an important public and reproductive health issue. The aim of this study is to investigate the extent to which physical and/or sexual intimate partner violence is associated with induced abortion and pregnancy loss from other causes and to compare this with other, more commonly recognized explanatory factors. Methods This study analyzes the data of the Tanzania section of the WHO Multi-Country Study on Women's Health and Domestic Violence, a large population-based cross-sectional survey of women of reproductive age in Dar es Salaam and Mbeya, Tanzania, conducted from 2001 to 2002. All women who answered positively to at least one of the questions about specific acts of physical or sexual violence committed by a partner towards her at any point in her life were considered to have experienced intimate partner violence. Associations between self reported induced abortion and pregnancy loss with intimate partner violence were analysed using multiple regression models. Results Lifetime physical and/or sexual intimate partner violence was reported by 41% and 56% of ever partnered, ever pregnant women in Dar es Salaam and Mbeya respectively. Among the ever pregnant, ever partnered women, 23% experienced involuntary pregnancy loss, while 7% reported induced abortion. Even after adjusting for other explanatory factors, women who experienced intimate partner violence were 1.6 (95%CI: 1.06,1.60 times more likely to report an pregnancy loss and 1.9 (95%CI: 1.30,2.89 times more likely to report an induced abortion. Intimate partner violence had a stronger influence on induced abortion and pregnancy loss than women's age, socio-economic status, and number of live born children. Conclusions Intimate partner violence is likely to be an important influence on levels of induced abortion and pregnancy loss in Tanzania. Preventing intimate partner violence may therefore be beneficial

To determine whether placenta previa increases bleeding during second-trimester pregnancy termination. The records of 131 consecutive women undergoing elective pregnancy termination at 13-24 weeks' gestation were reviewed and divided into those with and without placenta previa based on an ultrasound examination before the procedure. These two groups were then compared for differences in maternal characteristics, estimated blood loss, operative time, infection, and hospital admission. Twenty-three of 131 women (17.6%) had placenta previa. Sixty-seven percent of the previa patients smoked, versus 37% in the control group, a statistically significant difference. A statistical difference was noted with respect to placenta previa in intraoperative blood loss (P < .05), but not operative time, time to discharge, infection, hemorrhage, or other complications. Second-trimester pregnancy terminations in the presence of placenta previa are associated with a higher estimated blood loss, but no apparent increase in abortion-related infection, postoperative transfusion requirements, hysterectomy, or other complications.

This work aims at testing for the association of the methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms with unexplained recurrent pregnancy loss (RPL) among Egyptian women. Participants were 70 cases having a history of two or more events of unexplained RPL and 136 controls with a good obstetric history. Detection of MTHFR C677T and A1298C mutations was done by polymerase chain reaction with restriction fragment length polymorphisms assay using restriction enzymes HinfI and MboII respectively. Compared with controls, cases with unexplained pregnancy loss showed higher frequency of the homozygous mutant MTHFR 677 TT, 1298 CC genotypes, and the mutant haplotype 677T/1298C, although not reaching statistical significance. The frequency of 677 mutant genotypes (TT or TC) combined with either the mutant 1298 (CC or AC) or normal 1298 (AA) genotypes was significantly increased among cases with late-stage pregnancy loss versus those with early-stage pregnancy loss (p=0.001). There was also increased frequency of the 677 mutant genotypes among cases with secondary infertility compared with those with primary infertility and among cases with pregnancy loss >4 times compared with those with ≤4 times but with no statistical significance. Regarding other risk factors, it was noted that the frequency of mutations among cases with no or just one risk factor did not differ significantly from those having two or more risk factors (p=0.98). Mutations related to the MTHFR gene are increased but not statistically significant in Egyptian women with unexplained pregnancy loss. Interaction with other genetic variants might be speculated and need to be investigated.

Transvaginal colour and angio Doppler blood flow analysis combined with serial measurement of human chorionic gonadotrophin (HCG) concentration is reported here for the first time to study the local vascularity of a cornual pregnancy and to monitor the effectiveness of medical therapy. Interestingly, a strong relationship between morphological changes of trophoblastic tissue and the intensity of neovascularization was noted. Systemic single-dose methotrexate (MTX) therapy allowed successful treatment of an interstitial ectopic pregnancy involving part of the proximal portion of a tubal stump. We suggest that, by adding colour Doppler to conventional transvaginal ultrasonography, the outpatient surveillance of ectopic pregnancy evolution following MTX therapy is greatly enhanced. This is of particular value in cornual pregnancies which are highly likely to develop harmful complications during surgical intervention or even during puncture for local MTX injection.
Full Text Available Abstract Spontaneous perforations of the biliary tract are rare in adults and even more so during pregnancy. Perforation of the gall bladder is a potentially fatal complication of cholecystitis. The infrequency of perforation in the setting of calculous disease of the gall bladder is probably due to the thickened wall of the organ that has long been the seat of chronic inflammation. Common bile duct perforations have been reported in adults most commonly in association with choledocholithiasis. The diagnosis of biliary tract perforations is often delayed due to their non specific symptoms, which results in high morbidity. Early diagnosis and aggressive therapy are mandatory to alleviate this condition. Delayed diagnoses and treatment may have more serious consequences for pregnant women than for other patients. Very few cases of biliary tract perforations have been reported in pregnant women. We report two such cases in pregnancy: first of a gall bladder perforation associated with cholelithiasis and the second of a common bile duct perforation in pregnancy in which no apparent cause was found.

The researchers conducted a cross-sectional survey to determine the relationship between handling heavy items during pregnancy and spontaneous abortion among working women in South Korea. One thousand working women were selected from a database of those eligible for maternity benefits under the National Employment Insurance Plan. Study results showed that handling heavy items during pregnancy was associated with an increased risk of spontaneous abortion after adjusting for general characteristics of the participants and their work environment. A collective effort is needed on the parts of employers, employees, occupational health nurses, and the government to protect working women from lifting heavy items while pregnant.

This study provides evidence on the principal determinants of pregnancy and abortion in India using a large country-wide district-level data set (DLHS 2007). The paper provides an economic framework for the analysis of pregnancy and abortion. The study distinguishes between induced and spontaneous abortion and compares the effects of their determinants. The results show that there are wide differences between induced and spontaneous abortions in terms of the sign and magnitude of the estimated effects of several of their determinants, most notably wealth, the woman's age and her desire for children. The study makes a methodological contribution by proposing a trivariate probit estimation framework that recognizes the joint dependence of pregnancy and induced and spontaneous abortion, and provides evidence in support of this joint dependence. The study reports an inverted U-shaped effect of a woman's age on her pregnancy and both forms of abortion. The turning point in each case is quite robust to the estimation framework. A significant effect of contextual variables, at the village level, constructed from the individual responses, on a woman's pregnancy is found. The effects are weaker in the case of induced abortion, and insignificant in the case of spontaneous abortion. The results are shown to be fairly robust. This paper extends the literature on the relation between son preference and fertility by examining the link between mother's son preference and desire for more children with abortion rates.

Recurrent pregnancy loss (RPL) is defined by two or more failed pregnancies and accounts for only 1-5% of pregnancy failures. Treatment options for unexplained RPL (uRPL) are limited. Previous studies suggest a link between delayed implantation and pregnancy loss. Based on this, a timely signal for rescue of the corpus luteum (CL) using human chorionic gonadotrophin (HCG) could improve outcomes in women with uRPL. This retrospective cohort study included 98 subjects with uRPL: 45 underwent 135 monitored cycles without HCG support; and 53 underwent 142 cycles with a single mid-luteal HCG injection. Based on Log-rank Mantel-Cox survival curves, miscarriage rate and time to pregnancy decreased in the HCG group (P = 0.0005). Women receiving luteal HCG support had an increased chance of an ongoing pregnancy compared with those not receiving it (RR = 2.4; 95% CI 1.4-3.6; number need to treat (NNT) = 7; 95% CI 4-18). Subjects receiving HCG support had a significant absolute risk reduction (ARR) of miscarriage (P HCG in women with RPL appears warranted. Copyright Â© 2016 Reproductive Healthcare Ltd.

State of knowledge about misoprostol's use out of its marketing authorization during the first trimester of pregnancy, in early miscarriage or to induce abortion or medical termination of pregnancy. French and English publications were searched using PubMed, Cochrane Library and international learned societies recommendations. Cervical ripening prior to surgical uterine evacuation during the first trimester of pregnancy facilitates cervical dilatation and reduces operative time and uterine retention risk. Misoprostol, mifepristone and osmotic cervical dilators are equally efficient. Concerning first trimester miscarriage, surgical uterine evacuation remains the most effective and the quickest method of treatment (EL 1). Depending on the clinical situation, medical treatment using misoprostol (missed miscarriage) or expectative attitude (incomplete miscarriage) does not increase the risk of complications, neither haemorrhagic nor infectious (EL 1). However, these alternatives generally require longer outpatient follow-up, which leads to more consultations, prolonged bleeding and not planned surgical procedures (EL 1). Concerning missed miscarriage, a vaginal dose of 800 μg of misoprostol, possibly repeated 24 to 48 hours later, seems to offer the best efficiency/tolerance ratio (EL 2). Concerning early abortion, medical method is a safe and efficient alternative to surgery (EL 2). Success rates are inversely proportional to gestational age (EL 2). According to the modalities of its marketing authorization, 400 μg of misoprostol can only be given by oral route, for less than 7 weeks of amenorrhea (WA) pregnancies and after 36 to 48 hours following 600 mg of mifepristone (EL 1). However, 200mg of mifepristone is as efficient as 600 mg (EL 1). Beyond 7WA, misoprostol buccal dissolution (sublingual or prejugal) or vaginal administration are more efficient and better tolerated than oral ingestion (EL 1). Between 7 and 9WA, the best protocol in terms of efficiency and

The Democratic Republic of the Congo (DRC) has one of the highest rates of violence against women in the world; however, few studies have focused on this issue. In this study, we assessed the interrelationship among intimate partner violence (IPV), unintended pregnancy, pregnancy loss, and other sociodemographic factors in the DRC. Our analyses were based on data from the DRC demographic and health survey, conducted from November 2013 to February 2014. We constructed generalized estimating equation models to analyze the data from a sample of 5,120 married women. Our results showed that having a husband or partner who exhibited controlling behaviors, women who justified wife-beating, having a mother who had experienced IPV, and having a husband or partner who consumed alcohol were positively associated with IPV, whereas decision-making autonomy among women was negatively associated with IPV. In the community, the proportion of women who had experienced IPV and that of those who had completed secondary or higher education were positively and negatively associated with any IPV type, respectively. In addition, emotional IPV and any IPV type were positively associated with pregnancy loss. Our results indicate the necessity of implementing programs targeting gender equality at both individual and community levels.
The reproductive story offers a unique way to conceptualize pregnancy loss and infertility. This article describes the development of the reproductive story from early childhood on, and focuses on the devastating losses when the story does not unfold as originally hoped. Regardless of the type of reproductive trauma that clients experience, the underlying psychological constructs of grief are the same. The goal is to help clients work through their grief and loss, accept that their story can be edited and rewritten, and come away with a positive new ending. This paper illustrates how to utilize the reproductive story with infertility and pregnancy loss clients in psychotherapy. Using clinical illustrations, interventions for the treatment of perinatal grief, particularly in the context of infertility, are discussed. Specific suggestions are offered to help clients rethink past ideals, cope with their current trauma, and make constructive decisions in their effort to build their future family.

In this study, the acquisition of Dutch finite verb morphology is investigated in children with cochlear implants (CIs) with profound hearing loss and in children with hearing aids (HAs) with moderate to severe hearing loss. Comparing these two groups of children increases our insight into how hearing experience and audibility affect the acquisition of morphosyntax. Spontaneous speech samples were analyzed of 48 children with CIs and 29 children with HAs, ages 4 to 7 years. These language samples were analyzed by means of standardized language analysis involving mean length of utterance, the number of finite verbs produced, and target-like subject-verb agreement. The outcomes were interpreted relative to expectations based on the performance of typically developing peers with normal hearing. Outcomes of all measures were correlated with hearing level in the group of HA users and age at implantation in the group of CI users. For both groups, the number of finite verbs that were produced in 50-utterance sample was on par with mean length of utterance and at the lower bound of the normal distribution. No significant differences were found between children with CIs and HAs on any of the measures under investigation. Yet, both groups produced more subject-verb agreement errors than are to be expected for typically developing hearing peers. No significant correlation was found between the hearing level of the children and the relevant measures of verb morphology, both with respect to the overall number of verbs that were used and the number of errors that children made. Within the group of CI users, the outcomes were significantly correlated with age at implantation. When producing finite verb morphology, profoundly deaf children wearing CIs perform similarly to their peers with moderate-to-severe hearing loss wearing HAs. Hearing loss negatively affects the acquisition of subject-verb agreement regardless of the hearing device (CI or HA) that the child is wearing. The
uterus bicornis was diagnosed. The fetus and placenta were found in the abdominal cavity. Spontaneous rupture of the pregnant uterus generally occurs in congenitally malformed uteri like unicornuate or bicornuate uterus with or without rudimentary communicating-noncommunicating horn. It can be life threatening and should be diagnosed and treated immediately.

Will the addition of 24-chromosome microarray analysis on miscarriage tissue combined with the standard American Society for Reproductive Medicine (ASRM) evaluation for recurrent miscarriage explain most losses? Over 90% of patients with recurrent pregnancy loss (RPL) will have a probable or definitive cause identified when combining genetic testing on miscarriage tissue with the standard ASRM evaluation for recurrent miscarriage. RPL is estimated to occur in 2-4% of reproductive age couples. A probable cause can be identified in approximately 50% of patients after an ASRM recommended workup including an evaluation for parental chromosomal abnormalities, congenital and acquired uterine anomalies, endocrine imbalances and autoimmune factors including antiphospholipid syndrome. Single-center, prospective cohort study that included 100 patients seen in a private RPL clinic from 2014 to 2017. All 100 women had two or more pregnancy losses, a complete evaluation for RPL as defined by the ASRM, and miscarriage tissue evaluated by 24-chromosome microarray analysis after their second or subsequent miscarriage. Frequencies of abnormal results for evidence-based diagnostic tests considered definite or probable causes of RPL (karyotyping for parental chromosomal abnormalities, and 24-chromosome microarray evaluation for products of conception (POC); pelvic sonohysterography, hysterosalpingogram, or hysteroscopy for uterine anomalies; immunological tests for lupus anticoagulant and anticardiolipin antibodies; and blood tests for thyroid stimulating hormone (TSH), prolactin and hemoglobin A1c) were evaluated. We excluded cases where there was maternal cell contamination of the miscarriage tissue or if the ASRM evaluation was incomplete. A cost analysis for the evaluation of RPL was conducted to determine whether a proposed procedure of 24-chromome microarray evaluation followed by an ASRM RPL workup (for those RPL patients who had a normal 24-chromosome microarray evaluation

Full Text Available Laminin-1 is a major component and multifunctional glycoprotein of basement membranes that consists of three different subunits, α1, β1 and γ1 chains. It is the earliest synthesized network-forming protein during embryogenesis and plays an important role in embryonic development, embryonic implantation and placentation. We have recently shown that IgG anti-laminin-1 antibodies were significantly associated with recurrent first-trimester miscarriages and with subsequent pregnancy outcome. Interestingly, these antibodies were also observed in patients with endometriosis-associated infertility but not in patients with other causes of infertility, including tubal factors, hormonal and uterine abnormalities. Laminin-α1, -β1 and -γ1 mRNAs have been detected in 90% of endometriotic lesions and all laminin-α1, -β1 and -γ1 chains were localized in the basement membranes of glandular epithelium in endometriotic peritoneal lesions. Western blot analysis showed that anti-laminin-1 antibodies from those patients reacted with all laminin-1's chains. ELISA also confirmed that one of the target epitopes for these antibodies was located in a particular region of the laminin-1 molecule, i.e. the carboxyl-terminal globular G domain of α1 chain. IgM monoclonal anti-laminin-1 autoantibody, that we recently established, also recognized the G domain. Anti-laminin-1 antibodies from mice immunized with –mouse— laminin-1, caused a higher fetal resorption rate with lower embryonic and placental weights. Thus, anti-laminin-1 antibodies may be important in development of autoimmune-mediated reproductive failures and the assessment of the antibodies may provide a novel non-invasive diagnosis of endometriosis.

To examine the associations between tobacco exposure and adverse pregnancy outcomes using quantitative measures of lifetime active smoking and secondhand smoke (SHS) exposure. Historical reproductive data on 80 762 women who participated in the Women's Health Initiative Observational Study were examined with a cross-sectional analysis. We assessed self-reported lifetime active and passive tobacco smoke exposure, self-reported spontaneous abortions, stillbirths and ectopic pregnancies. When compared with never-smoking women, participants who were ever active smokers during their reproductive years had ORs (OR) of 1.16 (95% CI 1.08 to 1.26) for 1 or more spontaneous abortions, 1.44 (95% CI 1.20 to 1.73) for 1 or more stillbirths, and 1.43 (95% CI 1.10 to 1.86) for 1 or more ectopic pregnancies. Never-smoking women participants with the highest levels of lifetime SHS exposure, including childhood >10 years, adult home >20 years and adult work exposure >10 years, when compared with never-smoking women with no SHS exposure had adjusted ORs of 1.17 (95% CI 1.05 to 1.30) for spontaneous abortion, 1.55 (95% CI 1.21 to 1.97) for stillbirth, and 1.61 (95% CI 1.16 to 2.24) for ectopic pregnancy. Women who were ever-smokers during their reproductive years had significantly greater estimates of risk for spontaneous abortion, stillbirth and tubal ectopic pregnancy. Never-smoking women with the highest levels of lifetime exposure to SHS had significantly increased estimates of risk for spontaneous abortion, stillbirth and tubal ectopic pregnancy.

CONCLUSIONS: This case study suggests that even though as microperforated hymen surgery in puberty can permit pregnancy and intervention with cesarean section and hymenotomy is a good option to reduce the resulting perioperative complications which indirectly affect the increase of the fertilisation and improvement of later sexual life.

This study is part of a longitudinal cohort undertaken in both women and men to describe live birth outcome after undergoing assisted reproductive technology (ART) treatment in a clinical setting. Another objective was to follow women and men living with children from other alternatives after ART, such as adoption. A total of 439 (80.5%) women and 423 (77.6%) men were included in the baseline cohort (2005-2007). Live birth rate after ART was 24.8% at baseline. Up to 5 years later (2010-2011) the same participants were sent individual postal questionnaires (n = 439). Overall, 278 (63.3%) women and 183 (41.7%) men filled in and returned the questionnaire at follow up. The majority of women (91.7%) and men (93.4%) were living with children. A total of 225 (80.9%) women had a live birth at follow up. Of these, almost three of four (71.6%) had a live birth after ART and more than one of four (28.0%) after spontaneous pregnancies or both. Of these, 52 (26.1%) women had a subsequent live birth after successful ART and 26 (32.9%) women after unsuccessful ART. Nineteen (6.8%) women and 13 (7.1%) men had a child after adoption. Almost one of five (19.1%) women had no live birth at follow up. The majority of women and men were living with children, resulting from a live birth after ART, spontaneous pregnancy and/or adoption up to 5 years later. However, almost one of five had no live birth at follow up. © 2017 The Authors.

Violence by an intimate partner is increasingly recognized as an important public and reproductive health issue. The aim of this study is to investigate the extent to which physical and/or sexual intimate partner violence is associated with induced abortion and pregnancy loss from other causes and to compare this with other, more commonly recognized explanatory factors. This study analyzes the data of the Tanzania section of the WHO Multi-Country Study on Women's Health and Domestic Violence, a large population-based cross-sectional survey of women of reproductive age in Dar es Salaam and Mbeya, Tanzania, conducted from 2001 to 2002. All women who answered positively to at least one of the questions about specific acts of physical or sexual violence committed by a partner towards her at any point in her life were considered to have experienced intimate partner violence. Associations between self reported induced abortion and pregnancy loss with intimate partner violence were analysed using multiple regression models. Lifetime physical and/or sexual intimate partner violence was reported by 41% and 56% of ever partnered, ever pregnant women in Dar es Salaam and Mbeya respectively. Among the ever pregnant, ever partnered women, 23% experienced involuntary pregnancy loss, while 7% reported induced abortion. Even after adjusting for other explanatory factors, women who experienced intimate partner violence were 1.6 (95%CI: 1.06,1.60) times more likely to report an pregnancy loss and 1.9 (95%CI: 1.30,2.89) times more likely to report an induced abortion. Intimate partner violence had a stronger influence on induced abortion and pregnancy loss than women's age, socio-economic status, and number of live born children. Intimate partner violence is likely to be an important influence on levels of induced abortion and pregnancy loss in Tanzania. Preventing intimate partner violence may therefore be beneficial for maternal health and pregnancy outcomes. © 2012 Stöckl et al

Involuntary infertility and induced abortion exist on opposite sides of the spectrum: the first being the unwanted loss of childbearing potential while the second is the intentional termination of pregnancy. However, this paper proposes that these two poles of pregnancy loss are in fact related in Yoruba society, Nigeria. This argument is supported by qualitative and quantitative data drawn from an applied research project in communities and health institutions of Lagos State, from 1996 to 1999, where a total of 693 women recounted 1114 personal abortion experiences, and 233 women shared their experiences of fertility problems. Study statistics show that 37% of secondary infertility was most probably the result of induced abortion and that half of women with abortion complications interviewed in a referral hospital will have fertility problems. This paper provides insight into the reasons why single and married women decide to abort, and use unsafe methods, despite awareness of the serious health risks, including infertility. This is paradoxical given that fear of infertility is a major reason why women do not use modern contraceptives when trying to prevent unwanted pregnancy. By analysing the relations between infertility and abortion within the socio-cultural, economic, and services-related structures that influence women's decisions, this paper suggests ways of addressing the problems related to both types of pregnancy loss.

BACKGROUND The human leucocyte antigen (HLA) class Ib molecules, HLA-E, -F and -G, are expressed at the materno-fetal interface. Because of the apparent immunoregulatory functions of these proteins, they may be involved in successful acceptance of the semi-allogenic fetus during pregnancy. METHODS...... The literature on polymorphisms of the three genes, expression patterns of the proteins, and interactions with immune cell receptors have been evaluated to elucidate whether HLA-E, -F and -G are involved in the pathogenesis of some cases of recurrent miscarriages and unexplained infertility. RESULTS...... the functions of HLA-E, -F and -G future studies need to link investigations of the polymorphisms in these genes to measurements of protein levels, and examine the role of these proteins in the complex interplay of immune cells and cytokines at the materno-fetal interface....

Full Text Available The aim of this study was to estimate the changes in humoral immunity and their association with complications of pregnancy (spontaneous abortions, threatened miscarriage, premature birth depending on the gestational age and recurrence of cytomegalovirus infection (CMVI. A direct relationship between the frequency of detection of an anti-CMV IgG antibody titer of 1:1600 and the prevalence of acute respiratory disease during pregnancy has been identified. We found an imbalance in the production of the non-specific antibodies (an increase in the blood levels of total IgM and a decrease in IgA and IgG levels in the subgroup of women with relapsed CMVI at 6 to 8 weeks of gestation and spontaneous abortion, as well as in the subgroup of women with relapsed CMVI at 15 to 21 weeks of gestation and the risk of the late miscarriage, compared to those with relapsed CMVI at 9 to 14 weeks and 22 to 32 weeks of gestation. An increase in blood levels of total IgM and IgG and a decrease in IgA level was identified in the subgroup of women with relapsed CMVI at 9 to14 weeks of gestation and a threatened abortion, as well as in the subgroup of women with relapsed CMVI at 22 to 32 weeks of gestation and preterm birth. The obtained data of the imbalance in the primary and secondary immune response in CMV- seropositive pregnant women during relapsed CMVI indicate disturbances in the systemic and local intercellular interactions of immunocompetent cells, which lead to an imbalance in the production of antibodies involved in the elimination of viral agents and to the development of a systemic inflammatory response that complicates the course of pregnancy. CMVI relapse at 7 to 8 weeks of gestation is associated with reproductive losses; a risk for threatened miscarriage, threatened premature labor, and retrochorial hematoma increases significantly with CMVI relapse in the more remote gestational age.
Full Text Available To comparatively analyze the human microRNA (miRNA profiles between spontaneous decidualized menstrual endometrium and early pregnancy decidua by an in-depth sequencing of miRNAs. The specific miRNAs expressed at conception might be involved in pregnancy establishment and expression of let-7f-5p and let-7g-5p was experimentally up-regulated or inhibited to assess the effect on the expression of IGF2BP-1 and IGF2R in vitro, respectively. Samples of endometria and deciduas were obtained from 25 women who suffered from tubal or male factor subfertility and from 35 early pregnant women who underwent pregnancy termination at 6-8 weeks gestation were irrespectively collected and comparatively analyzed by miRNA sequencing and differential expression of known and novel miRNAs was analyzed using bioinformatics. The 2042 miRNA expression was analyzed in the study and the differential expression of six miRNAs was validated by qRT-PCR. The expression of four miRNAs in decidua samples was down-regulated (miR-34c, miR-92a, miR-181a-5p, and miR-191, whereas the expression of miR-10a-5p and let-7f-5p was significantly up-regulated. The expression of IGF2BP-1 and IGF2R declined and increased with overexpression and inhibition of let-7f-5p and let-7g-5p, respectively. Changes in the expression of particular miRNAs might play a role in the physiology of decidualization following successful embryo implantation, ultimately resulting in continuous decidualization.

Loss of hepatitis B surface antigen (HBsAg) usually indicates the cure of hepatitis B virus (HBV) infection. In spontaneous hepatitis B e antigen (HBeAg) seroconverters, lower serum HBsAg and HBV DNA levels have been shown to be associated with HBsAg loss over time. However, little is known about their impacts on HBsAg loss in HBeAg-negative patients with limited viral replication. A total of 688 HBeAg-negative patients with baseline serum HBV DNA levels loss were investigated. In a mean follow-up of 11.6 years, the average annual rate of HBsAg loss was 1.6%. Baseline HBsAg and HBV DNA levels were inversely associated with subsequent HBsAg loss. When compared to patients who had HBsAg levels >1000 IU/mL, the rates of HBsAg loss were significantly higher in patients with HBsAg levels of 100-999, 10-99, and loss was 13.2 (95% CI, 7.8-22.1) for HBsAg level loss.

Women of childbearing age represent 31%-36% of patients undergoing bariatric surgery. However, the influence of pregnancy before or after bariatric surgery on surgery outcomes is unclear. The aim of the present study was to compare the effect of pregnancy before and after bariatric surgery on overall weight loss. An academic center in the United States. All female patients who had a successful pregnancy between 2005 and 2014 were included. The window of inclusion was≤3 years, either before or after surgery. Control patients included a cohort of female patients who had not been pregnant, matched on a 2:3 ratio for age, initial body mass index, type of procedure, and duration of follow-up. A total of 62 patients delivered within 3 years either before or after surgery. Data were compared with a matched cohort of 92 patients who had never conceived. Mean age at surgery was 33.8 years, and mean body mass index at surgery was 48.2 kg/m(2). Laparoscopic Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric banding were performed in 75.9%, 12.9%, and in 11.0% of cases, respectively. After an average matched follow-up period of 43.9 months, percentage excess weight loss was 68.0%±26.0% in the nonpregnant group compared with 53.0%±25.0% in the pregnant group (Pbariatric surgery had a more negative effect on weight loss compared with patients who had never been pregnant (odds ratio: -3.8; 95% confidence interval, -6.6 to -1.0; Pbariatric surgery increases the likelihood of reduced weight loss after surgery. Patients wishing to conceive should be informed that weight loss outcomes may vary depending on the timing of pregnancy relative to bariatric surgery.

Field observations of 400 totally unmanaged feral horses on Sable Island, Nova Scotia, were complemented by oestrogen determinations in faecal samples from 154 identified females over a 4-year period (454 mare-years). Of mares that were sampled throughout the year and subsequently produced foals, 92.1% exhibited elevated faecal oestrogens between 15 October and 30 March. The results confirm that faecal oestrogens are a useful indicator of pregnancy after approximately 120 days gestation. Distribution of foaling resembled that seen in other feral populations, with 95% of births occurring from April through July. The foaling rate for mares aged 3 years or older was 62.0%, with 50.7% of mares foaling in 3 or 4 years. Foaling rates were low (4.1%) in mares bred as yearlings and rose with age to 70.8% in those bred as 4-year-olds. Fetal loss after Day 120 was deduced from faecal oestrogens to be 26.0% overall, with marked variation from year to year (9.6-37.3%) and with age (70.0% in those bred as yearlings, decreasing to 5.6% in those bred as 4-year-olds). Of 58 mares aged 2 years or older that were sampled every year, about half (49.6%) the barren years were attributable to fetal loss after 120 days gestation. All mares conceived in at least 2 of the 4 years, suggesting that pregnancy loss, even after Day 120, is as important as failure to conceive in causing barren years.

The study sought to identify determinants of blood loss at childbirth and 24 hours postpartum. The study was nested in a community-based randomized trial of treatments for anaemia during pregnancy in Wete Town, Pemba Island, Zanzibar, United Republic of Tanzania. Status of anaemia during pregnancy, nutritional information, obstetric history, and socioeconomic status were assessed at enrollment during routine antenatal care. Pregnant women presented for spontaneous vaginal delivery, and nurse-midwives collected information on labour and delivery via partograph. Blood-stained sanitary napkins and pads from childbirth and 24 hours postpartum were quantified using the alkaline hematin method. Moderate-to-severe anaemia (Hb delivery and the immediate postpartum period, after adjusting for maternal covariates and variables of biological relevance to blood loss. Greater blood loss was associated (pbirth, and grand multiparity. The findings provide unique evidence of a previously-suspected link between maternal anaemia and greater blood loss at childbirth and postpartum. Further research is needed to confirm these findings on a larger sample of women to determine whether women with moderate-to-severe anaemia are more likely to experience postpartum haemorrhage and whether appropriate antenatal or peripartum care can affect the relationships described here.

Rudimentary uterine horn pregnancy is rare and, to our knowledge, has not been previously reported in Cameroon. We herein report the case of a 22 year old second gravida referred for acute abdominal pain at 17 weeks of gestation. Physical examination revealed hemoperitoneum with hypovolemic shock. After resuscitation, an emergency exploratory laparotomy was done and we found hemoperitoneum of 3,500 milliliters, a bicornuate uterus with a ruptured right rudimentary communicating horn containing a non viable foetus. There were no other abnormalities. We performed an excision of the rudimentary horn with ipsilateral salpingectomy. Post-operative course was uneventful and the woman was discharged seven days later. This case emphasizes the importance of good antenatal care to avoid complications.
A research trajectory is reported that created state-of-the-art interdisciplinary guidelines for care of women and their families who arrive in the emergency department with pregnancy loss. These guidelines include attention to mother and family bereavement as well as care of the fetus. Design was a triangulated non-experimental exploratory action research for the purpose of changing practice. Included were: (1) A qualitative study of emergency room nurses and physicians to assess beliefs/barriers to providing optimal care for pregnancy loss patients. (2) A focus group of perinatal bereavement providers; (3) Another focus group in the form of a sponsored National Summit of professional and lay experts and (4) A Delphi Study to craft language for national position statement. Results allowed the creation of interdisciplinary guidelines from the National Perinatal Association. These guidelines are being adopted by organizations and facilities throughout the United States. Training programs for emergency department personnel have been created by pregnancy loss organizations and are available.

Full Text Available After ovulation, non-pregnant female giant pandas experience pseudopregnancy. During pseudopregnancy, non-pregnant females exhibit physiological and behavioral changes similar to pregnancy. Monitoring hormonal patterns that are usually different in pregnant mammals are not effective at determining pregnancy status in many animals that undergo pseudopregnancy, including the giant panda. Therefore, a physiological test to distinguish between pregnancy and pseudopregnancy in pandas has eluded scientists for decades. We examined other potential markers of pregnancy and found that activity of the acute phase protein ceruloplasmin increases in urine of giant pandas in response to pregnancy. Results indicate that in term pregnancies, levels of active urinary ceruloplasmin were elevated the first week of pregnancy and remain elevated until 20-24 days prior to parturition, while no increase was observed during the luteal phase in known pseudopregnancies. Active ceruloplasmin also increased during ultrasound-confirmed lost pregnancies; however, the pattern was different compared to term pregnancies, particularly during the late luteal phase. In four out of the five additional reproductive cycles included in the current study where females were bred but no birth occurred, active ceruloplasmin in urine increased during the luteal phase. Similar to the known lost pregnancies, the temporal pattern of change in urinary ceruloplasmin during the luteal phase deviated from the term pregnancies suggesting that these cycles may have also been lost pregnancies. Among giant pandas in captivity, it has been presumed that there is a high rate of pregnancy loss and our results are the first to provide evidence supporting this notion.

New tools are required to identify women at increased risk of spontaneous preterm birth (sPTB). Quantitative texture analysis by ultrasound has been used to extract robust features from the ultrasound image of a given tissue to detect subtle changes in its microstructure. This may also be applied to the cervix. We aimed to determine if there is an association between quantitative analysis of the cervical texture (CTx) by ultrasound in the mid-trimester of pregnancy and sPTB quantitative analysis of the CTx. A learning algorithm was developed to obtain the best combination of cervical textures features associated with sPTB based on feature transformation and discriminant analysis-regression. The ability of the learning algorithm to predict sPTB was evaluated using a leave-one-out cross-validation technique, obtaining a CTx-based score for each individual. Receiver-operating characteristic (ROC) curves were drawn and sensitivity, specificity, positive and negative likelihood ratios were calculated for the optimal cut-off based on the ROC curve. The results were compared to those obtained with the CL. At all points the investigators studying the images were blinded to pregnancy outcome. Images of 310 women (27 cases and 283 controls) were of sufficient quality and included in the study. Median CTx-based score (-1.01 vs -0.07, p = Quantitative analysis of the cervical texture is able to extract information from the ultrasound images related to sPTB and generate a CTx-based score which is independently associated to sPTB.

Full Text Available The concept of a carbimazole embryopathy underlies current Endocrine Society advice to avoid this drug in early pregnancy, favouring propylthiouracil as an alternative for the treatment of maternal hyperthyroidism. We aimed to establish whether suspected spontaneous reporting of adverse drug reactions in the UK via the Yellow Card Scheme supports a carbimazole embryopathy and the lack of association between propylthiouracil and congenital anomalies. All birth defects related to maternal treatment with carbimazole or propylthiouracil reported over a 47-year period via the Yellow Card Scheme were analysed. 57 cases with 97 anomalies were reported following in utero exposure to carbimazole. These anomalies included aplasia cutis, choanal atresia, tracheo-oesophageal fistula, and patent vitellointestinal duct, which have previously been reported in association with carbimazole/methimazole exposure in utero. Only 6 cases with 11 anomalies were reported for propylthiouracil, all within the last 15 years. Therefore, these findings may support a carbimazole embryopathy. There are few birth defects associated with propylthiouracil, but this should be interpreted in the context of higher historical prescription rates for carbimazole.

To evaluate the effects of HIV viral load, measured cross-sectionally and cumulatively, on the risk of miscarriage or stillbirth (pregnancy loss) among HIV-infected women enrolled in the Women's Interagency HIV Study between 1994 and 2013. We assessed three exposures: most recent viral load measure before the pregnancy ended, log10 copy-years viremia from initiation of antiretroviral therapy (ART) to conception, and log10 copy-years viremia in the two years before conception. The risk of pregnancy loss for those with log10 viral load >4.00 before pregnancy ended was 1.59 (95% confidence interval (CI): 0.99, 2.56) times as high as the risk for women whose log10 viral load was ≤1.60. There was not a meaningful impact of log10 copy-years viremia since ART or log10 copy-years viremia in the two years before conception on pregnancy loss (adjusted risk ratios (aRRs): 0.80 (95% CI: 0.69, 0.92) and 1.00 (95% CI: 0.90, 1.11), resp.). Cumulative viral load burden does not appear to be an informative measure for pregnancy loss risk, but the extent of HIV replication during pregnancy, as represented by plasma HIV RNA viral load, predicted loss versus live birth in this ethnically diverse cohort of HIV-infected US women.

Background: Recurrent pregnancy loss (RPL) is a multifactorial disorder. Environmental factors and genetics can affect pregnancy outcomes. Objective: Conflicting data suggest an association between estrogen receptor alpha (ESR1) gene polymorphisms and RPL. In this study, such association was investigated in Iranian women with RPL. Materials and Methods: In this case control study, blood samples were collected from 244 women with a history of three or more consecutive pregnancy losses and 104 healthy women with at least two live births. Using polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP), we studied -397C/T and -351A/G polymorphisms on ESR1 gene in case and control subjects. Results: The genotypic frequencies of -397C/T and -351A/G polymorphisms on ESR1were not significantly different between RPL and control groups (p=0.20 and p=0.09, respectively). A significantly negative correlation was observed between -397C/T and -351A/G (r=-0.852, p<0.001) in RPL women and complete linkage disequilibrium between the investigated polymorphisms was found (D’: 0.959; r-square= 0.758, p<0.001). Conclusion: This investigation suggests that the analyzed polymorphisms on ESR1gene are not associated with an increased risk of RPL in the studied population. PMID:25071847
Full Text Available Selective serotonin reuptake inhibitors (SSRIs are the most frequently used antidepressants during pregnancy. There are conflicting results about their influence on pregnancy outcomes.The goal of this study was to update our previous meta-analysis about pregnancy outcomes following exposure to SSRIs. For this purpose, all relevant databases were searched from 1990 to March 2012 for studies investigating the pregnancy outcomes following exposure to any therapeutic dosage of any SSRI (fluoxetine, paroxetine, citalopram, escitalopram, sertraline, fluvoxamine during pregnancy. Types of outcome investigated were spontaneousabortion, major malformations, cardiovascular malformations, and minor malformations. A total of 25 studies met our criteria and were included in the meta-analysis. The odds ratio (OD values are 1.87 (95% CI: 1.5 to 2.33, P< 0.0001 for spontaneous abortion, 1.272 (95%CI: 1.098 to 1.474, P = 0.0014 for major malformations, 1.192 (95% CI: 0.39 to 3.644, P=0.7578 for cardiovascular malformations, and 1.36 (95% CI: 0.61 to 3.04, P= 0.4498 for minor malformations. The results demonstrated that SSRIs increase the risk of spontaneousabortion and major malformations during pregnancy while they don’t increase the risk of cardiovascular malformations and minor malformations. Our previous meta-analysis only showed an increase in the risk of spontaneous abortion following the use of SSRIs duringpregnancy. This might be due to increase in the number of studies included or addition of two new SSRIs (citalopram and escitalopram. The message to researchers is to try considering SSRIs individually during pregnancy to reduce heterogeneity, although all are aware ofinevitable limitations to study on pregnant mothers.

Pregnancy loss is common, but its significance is often minimized by family, friends, and the community, leaving bereaved parents with unmet need for support. This study sought to describe demographics, usage patterns, and perceived benefits for women participating in Internet pregnancy loss support groups. We requested permission to post an anonymous Internet survey on large and active United States Internet message boards for women with miscarriages and stillbirths. The study purposefully oversampled stillbirth sites and included both closed- and open-ended questions. The University of Michigan Institutional Review Board approved the study. Closed-ended questions were summarized and evaluated with bivariate analysis. We performed a qualitative analysis of open-ended data using an iterative coding process to identify key themes. Of 62 sites queried, 15 granted permission to post the survey on 18 different message boards. We collected 1,039 surveys, of which 1,006 were complete and eligible for analysis. Women were typically white, well educated, and frequent users. They noted message boards helped them to feel less isolated in their loss and grief and they appreciated unique aspects of Internet communication such as convenience, access, anonymity, and privacy. Pregnancy loss message boards are an important aspect of support for many bereaved mothers. African-American women seem to be substantially underrepresented on-line despite being at higher risk for stillbirth. Internet message boards serve a unique function in providing support for women with miscarriage and stillbirth. The benefits are often significantly different from those encountered in traditional face-to-face bereavement support. Copyright © 2012 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Full Text Available The development of genomic instability is an important step in generatingthe multiple genetic changes required for cancer. One consequence of genomic instability is the overexpression of oncogenes due to gene amplification. One mechanism for gene amplification is the breakagelfusionlbridge (B/F/Bcyclethatinvolvesthe repeated fusion and breakage of chromosomes following the loss of a telomere. B/F/B cycles have been associated with low-copy gene amplification in human cancer cells, and have been proposed to be an initiating event in high-copy gene amplification. We have found that spontaneous telomere loss on a marker chromosome 16 in a human tumor cell line results in sister chromatid fusion and prolonged periods of chromosome instability. The high rate of anaphase bridges involving chromosome 16 demonstrates that this instability results from B/F/B cycles. The amplification of subtelomeric DNA on the marker chromosome provides conclusive evidence that B/F/B cycles initiated by spontaneous telomere loss are a mechanism for gene amplification in human cancer cells.

To compare the analysis of chromosome number from paraffin-embedded products of conception using single-nucleotide polymorphism (SNP) microarray with the recommended screening for the evaluation of couples presenting with recurrent pregnancy loss who do not have previous fetal cytogenetic data. We performed a retrospective cohort study including all women who presented for a new evaluation of recurrent pregnancy loss over a 2-year period (January 1, 2012, to December 31, 2013). All participants had at least two documented first-trimester losses and both the recommended screening tests and SNP microarray performed on at least one paraffin-embedded products of conception sample. Single-nucleotide polymorphism microarray identifies all 24 chromosomes (22 autosomes, X, and Y). Forty-two women with a total of 178 losses were included in the study. Paraffin-embedded products of conception from 62 losses were sent for SNP microarray. Single-nucleotide polymorphism microarray successfully diagnosed fetal chromosome number in 71% (44/62) of samples, of which 43% (19/44) were euploid and 57% (25/44) were noneuploid. Seven of 42 (17%) participants had abnormalities on recurrent pregnancy loss screening. The per-person detection rate for a cause of pregnancy loss was significantly higher in the SNP microarray (0.50; 95% confidence interval [CI] 0.36-0.64) compared with recurrent pregnancy loss evaluation (0.17; 95% CI 0.08-0.31) (P=.002). Participants with one or more euploid loss identified on paraffin-embedded products of conception were significantly more likely to have an abnormality on recurrent pregnancy loss screening than those with only noneuploid results (P=.028). The significance remained when controlling for age, number of losses, number of samples, and total pregnancies. These results suggest that SNP microarray testing of paraffin-embedded products of conception is a valuable tool for the evaluation of recurrent pregnancy loss in patients without prior fetal

Full Text Available Aim. The determination of chromosomal abnormalities in samples from early pregnancy losses and allelic polymorphism of HLA–DRB1 and DQA1 genes in couples with recurrent miscarriage. Methods. Banding cytogenetic and interphase mFISH analysis, DNA extraction by salting method, PCR, agarose gel electrophoresis. Results. Cytogenetic and molecular-cytogenetic investigations of SA material identified karyotype anomalies in 32.4 % of cases with prevalence of autosomal trisomy – 42.65 %, triploidy – 30.38 % and monosomy X – 19.11 %. Complex analysis of frequency and distribution of allelic variants of genes HLA-DRB1 and HLA-DQA1 allowed establishing the alleles DRB1*0301, DRB1*1101-1104 and DQA1*0501 to be aggressor alleles in women with recurrent pregnancy loss (RPL. The cumulative homology of allelic polymorphism of more than 50 % of HLA-DRB1 and HLA-DQA1 loci between partners increases the risk of RPL by almost four times. Conclusion. The detected chromosome aneuploidies in the samples from products of conception and the changes in the major histocompatibility complex genes can cause the failure of a couples reproductive function and can lead to an early fetal loss.

Water constraints can mediate evolutionary conflict either among individuals (e.g., parent-offspring conflict, sexual conflict) or within an individual (e.g., cost of reproduction). During pregnancy, water is of particular importance because the female provides all water needed for embryonic development and experiences important maternal shifts in behavior and physiology that, together, can compromise female water balance if water availability is limited. We examined the effect of pregnancy on evaporative water loss and microhabitat selection in a viviparous snake, the aspic viper. We found that both physiological (increased metabolism and body temperature) and morphological (body distension) changes contribute to an increased evaporative water loss in pregnant females. We also found that pregnant females in the wild select warmer and moister basking locations than nonreproductive females, likely to mitigate the conflict between thermal needs and water loss. Water resources likely induce significant reproductive constraints across diverse taxa and thus warrant further consideration in ecological research. From an evolutionary perspective, water constraints during reproduction may contribute to shaping reproductive effort.

Have changes in culture media used for IVF resulted in changes in offspring birthweight or placental weight that differed from the trends in offspring from spontaneous conceptions during the corresponding time periods? Changes in culture media used for IVF were associated with significant differences in offspring birthweight and in placental weight to birthweight ratio when compared with the trend in offspring from spontaneous conceptions during the time periods. The effect of culture media used for IVF on offspring birthweight has varied between studies. There is a large variation in birthweight between newborns, and birthweight may vary across populations and over time. Such variations may therefore have influenced previous results. We included all singleton births from IVF at one treatment center in Norway during the years 1999-2011(n = 2435) and all singleton births from spontaneous conceptions in Norway during the same years (n = 698 359). Three different media were used for embryo culture; Medicult Universal IVF (1999 through 2007, n = 1584), Medicult ISM1 (2008 until 20 September 2009, n = 402) and Vitrolife G-1 PLUS (21 September 2009 through 2011, n = 449). We estimated mean birthweight and placental weight in IVF pregnancies by culture media. We also estimated mean weights in IVF and in spontaneous pregnancies by year of birth. Thereafter, we studied whether the changes in mean weights in IVF pregnancies differed from the changes in weight in spontaneous pregnancies in the periods corresponding to culture media changes by applying a grouped difference-in-difference analysis. Adjustments were made for parity, maternal age and gestational age at birth. In singleton offspring from IVF the mean birthweight was 3447.6 g with Medicult Universal, 3351.7 g with Medicult ISM1 and 3441.4 g with Vitrolife G-1 PLUS (P culture media in IVF pregnancies. Lack of adjustment for such possible factors may have biased our results. We found a significant effect of culture

Early B-cell factor 1 (EBF1) plays a central role in B-cell lineage specification and commitment. Loss of this critical transcription factor is strongly associated with high-risk, relapsed and therapy-resistant B-cell-acute lymphoblastic leukemia, especially in children. However, Ebf1 haploinsufficient mice exhibit a normal lifespan. To determine whether prolonged survival of B cells would enable tumorigenesis in Ebf1 haploinsufficient animals, we generated Ebf1 +/- Bcl-x L Tg mice, which express the anti-apoptotic factor Bcl-x L in B cells. Approximately half of Ebf1 +/- Bcl-x L Tg mice develop aggressive oligoclonal leukemia as they age, which engrafts in congenic wild-type recipients without prior conditioning. The neoplastic cells display a pre-B phenotype and express early developmental- and natural killer cell/myeloid-markers inappropriately. In addition, we found tumor cell-specific loss of several transcription factors critical for maintaining differentiation: EBF1, TCF3 and RUNX1. However, in the majority of tumors, loss of Ebf1 expression was not due to loss of heterozygosity. This is the first spontaneous mouse model of pre-B leukemia to demonstrate inappropriate expression of non-B-cell-specific genes associated with loss of Ebf1, Tcf3 and Runx1 expression.

We present the management of a case of failed medical and surgical management of second trimester pregnancy loss due to pregnancy in a non-communicating rudimentary horn. A 16-week intrauterine fetal death singleton pregnancy was referred to us after failed medical and surgical termination of pregnancy. Ultrasound confirmed the diagnosis and showed minimal blood clots and fluid in the pouch of Douglas. Laparoscopy showed a soft, enlarged right uterine horn not communicating with the cervix and containing the pregnancy, and a left uterine horn communicating with the cervix and showing a posterior wall perforation. The procedure was converted to laparotomy, and the right uterine horn and adjacent tube were excised. The patient made an uneventful recovery and was discharged after 3 days. Pregnancy in a non-communicating horn is rare and usually presents with serious complications. Any case of failed medical termination of pregnancy after repeated doses of misoprostol should be carefully assessed to exclude the possibility of uterine anomalies (especially in a primigravida), before proceeding with dilatation and evacuation to minimise the risk of complications.

Retrospective study. To study the behavior of the unfused thoracic curve in Lenke type 5C during the follow-up and to identify risk factors for its correction loss. Few studies have focused on the spontaneous behaviors of the unfused thoracic curve after selective thoracolumbar or lumbar fusion during the follow-up and the risk factors for spontaneous correction loss. We retrospectively reviewed 45 patients (41 females and 4 males) with AIS who underwent selective TL/L fusion from 2006 to 2012 in a single institution. The follow-up averaged 36 months (range, 24-105 months). Patients were divided into two groups. Thoracic curves in group A improved or maintained their curve magnitude after spontaneous correction, with a negative or no correction loss during the follow-up. Thoracic curves in group B deteriorated after spontaneous correction with a positive correction loss. Univariate analysis and multivariate analysis were built to identify the risk factors for correction loss of the unfused thoracic curves. The minor thoracic curve was 26° preoperatively. It was corrected to 13° immediately with a spontaneous correction of 48.5%. At final follow-up it was 14° with a correction loss of 1°. Thoracic curves did not deteriorate after spontaneous correction in 23 cases in group A, while 22 cases were identified with thoracic curve progressing in group B. In multivariate analysis, two risk factors were independently associated with thoracic correction loss: higher flexibility and better immediate spontaneous correction rate of thoracic curve. Posterior selective TL/L fusion with pedicle screw constructs is an effective treatment for Lenke 5C AIS patients. Nonstructural thoracic curves with higher flexibility or better immediate correction are more likely to progress during the follow-up and close attentions must be paid to these patients in case of decompensation. 4.

Spontaneous preterm birth is a major cause of perinatal morbidity and mortality. It is unclear if a cervical pessary can reduce the risk of spontaneous preterm delivery. To test whether in asymptomatic women with singleton pregnancies and no prior spontaneous preterm birth but with short cervical length on transvaginal ultrasound, use of a cervical pessary would reduce the rate of spontaneous preterm birth at less than 34 weeks of gestation. Parallel-group, nonblinded, randomized clinical trial conducted from March 1, 2016, to May 25, 2017, at a single center in Italy. Asymptomatic women with singleton gestations, no previous spontaneous preterm births, and cervical lengths of 25 mm or less at 18 weeks 0 days to 23 weeks 6 days of gestation were eligible. Patients were randomized 1:1 to receive either cervical pessary (n = 150) or no pessary (n = 150). The pessary was removed between 37 weeks 0 days and 37 weeks 6 days of gestation or earlier if clinically indicated. The control group received standard care. For cervical length of 20 mm or shorter, women in both groups were prescribed vaginal progesterone, 200 mg/d, until 36 weeks 6 days of gestation. No bed rest or activity restriction was recommended. The primary end point was spontaneous preterm birth at less than 34 weeks of gestation. Secondary outcomes were adverse events. Among 300 women who were randomized (mean age, 29 [SD, 6.3] years; mean gestational age, 22 [SD, 1.3] weeks), 100% completed the trial. The primary end point occurred in 11 women (7.3%) in the pessary group and 23 women (15.3%) in the control group (between-group difference, -8.0% [95% CI, -15.7% to -0.4]; relative risk, 0.48 [95% CI, 0.24-0.95]). During follow-up, the pessary group had a higher rate of increased or new vaginal discharge (86.7% vs 46.0%; between-group difference, +40.7% [95% CI, +30.1%-+50.3%]; relative risk, 1.88 [95% CI, 1.57-2.27]). Among women without prior spontaneous preterm birth who had asymptomatic

Clearance of hepatitis B surface antigen (HBsAg) indicates clinical control of hepatitis B virus (HBV) infection. However, little is known about the impact of viral genomic variations on HBsAg loss. We explored the association between viral genomic factors and HBsAg loss in 2121HBeAg-negative patients. HBV pre-core stop codon (1896) and basal core promoter (BCP) (1762/1764) sequences were determined in patients with HBV DNA ≥200 IU/mL (N = 1693). The effect of HBV genotype on HBsAg loss was further validated in the whole cohort of 3445 HBsAg carriers. The cumulative lifetime (age 28-75 years) incidence of HBsAg loss was 50.4% in 2121 HBeAg-negative patients. We found that genotype C, but not pre-core stop codon or BCP mutants, was associated with HBsAg loss. Compared to genotype B patients, genotype C patients had higher lifetime chance of HBsAg loss, with hazard ratio of 1.8 (95% confidence interval: 1.4-2.4). Multivariable analysis showed that male sex, elevated ALT levels, lower serum HBV DNA and HBsAg levels, and genotype C infection were associated with higher chance of HBsAg loss independently. We then performed sensitivity analysis, which re-included HBeAg-positive, cirrhotic and treatment-experienced patients, and confirmed the robustness of our results in 3445 HBsAg carriers. Genotype C infection, compared to genotype B, is associated with a higher lifetime chance of HBsAg loss in Asian HBV carriers. © 2015 John Wiley & Sons Ltd.
Full Text Available AIM: The present study was aimed to define the incidence of antiphospholipid antibodies of different types lupus anticoagulant (LAC, venereal disease research laboratory test (VDRL and Beta2-glycoprotein I dependent anticardiolipin antibodies Beta2 I aCL in our cohort of population experiencing recurrent pregnancy loss (RPL from Andhra Pradesh, South India. SETTING AND DESIGN: A referral case-control study at a tertiary centre over a period of 5 years. PARTICIPANTS: 150 couples experiencing 3 or more recurrent pregnancy losses with similar number of matched controls. MATERIAL AND METHODS: LAC activity was measured by the activated partial thromboplastin time (aPTT according to the method of Proctor and Rapaport with relevant modifications. VDRL analysis was performed by the kit method supplied by Ranbaxy Diagnostics Limited and Beta2 Glycoprotein I dependent anticardiolipin antibodies were estimated by ELISA kit (ORGen Tech, GmbH, Germany with human Beta2 Glycoprotein I as co-factor. STATISTICAL ANALYSIS: Statistical analysis was performed using Student′s t test. RESULTS: LAC activity was found positive in 11 women (10.28%. The mean +/- SE Beta2 I aCL concentration in the study group was 14.53 (micro/ml +/- 1.79 (range 0 to 90.4 micro/ml which was higher than the control group with a mean +/- SE of 7.26 (micro/ml +/- 0.40 (range 0 to 18 u/ml. The binding of the antibodies to the antigen was observed in 40.24% (n=33 of the cases compared to 6.09% (n=5 in controls. VDRL test was positive in 7(2.34% individuals (3 couples and 1 male partner and none among controls. CONCLUSIONS: The present study indicates the importance of antiphospholipid antibodies in women experiencing RPL and suggests the usefulness of screening for these antibodies as a mandatory routine for instituting efficient therapeutic regimens for a successful outcome of pregnancy.

Gamma delta (γδ) T cells are known to link innate and adaptive immunity. Decidual γδ T cells are known to provide immunotolerance by producing IL-10 and TGF-β. In recurrent pregnancy loss (RPL) females, the role of peripheral γδ T cells remain unstudied. To investigate the different phenotypes of γδ T cells in the peripheral blood of women with idiopathic RPL and their possible involvement in RPL condition. A total of 120 women were recruited for the study. Peripheral blood lymphocytes were isolated and they were stained with appropriate antibodies to determine the phenotype of γδ T cells and major cytokines produced by them in the blood using flow cytometry. We observed a significant decrease in the proportion of CD3 + CD4 - CD8 - γδ T cells (p<0.001) and increase in the percentage of IFN-γ (p<0.05) and IL-17 (p<0.001) producing γδ T cells in RPL pregnant as compared to normal pregnant females. Increase in IFN-γ and IL-17-producing CD3 + CD4 - CD8 - γδ T cells is associated with creating inflammatory cytokine milieu, thereby, may contribute towards pregnancy loss in RPL females.

Full Text Available Background: Thrombophilias, both acquired and inherited, have been investigated in the etiopathogenesis of unexplained recurrent pregnancy loss. Aim: To study coagulation inhibitors and activated protein C resistance (APCR in recurrent pregnancy losses (RPL occurring in second and third trimesters. Materials and Methods: A total of 30 pregnant women (group A with two or more recurrent unexplained fetal loses were evaluated for APCR, protein C deficiency, protein S deficiency, antithrombin deficiency, and antiphospholipid antibodies (APLA. Thirty age-matched controls were taken (group B comprising of pregnant women with at least one live issue. Statistical Analysis: Comparisons between two group frequencies and group means were made using Chi square test and Student′s t test, respectively. Results: Protein C and protein S levels were reduced in group A compared with group B and the difference was statistically significant (P=0.005 and P=0.032, respectively. The mean value of antithrombin was slightly reduced in group A compared with group B. APCR was observed in 16.6% cases and 3.3% controls. However, the difference was not statistically significant. APLA was observed in 20% cases and none of the controls. Of these, lupus anticoagulant was positive in 16.6% cases and anticardiolipin antibodies in 10% cases. Combined defects were seen in seven patients. Conclusion: There is a significant risk of RPL in pregnant women with thrombophilias. Therefore, screening for thrombophilias may be justified in pregnant women with unexplained recurrent fetal wastage, especially in second and third trimester.

To evaluate residents' ability to engage standardized patients in informed decision making during a pregnancy loss scenario. Forty patient encounters between interns and standardized patients were coded to assess informed decision-making practices, exploration of unexpressed concerns, and support provision. Interns engaged in minimum informed decision making but did not address all of the communicative elements necessary for informed decisions, and most elements were only partially addressed. Patients in this study did not receive information about all management options, their concerns were not addressed, and there was limited support communicated for their decision. This study offers an initial assessment of a communicative approach to evaluate and improve decision making during early pregnancy loss. A comprehensive approach to making informed decisions must include discussion of all management options, exploration of patient preferences and concerns, and support for the patient's decision. Physicians could benefit from communication skills training to communicate more effectively with patients to help them make more informed decisions. Copyright © 2017 Elsevier B.V.

pleiotropy. It has also been proposed that the survival of long, conserved haplotypes may be due to gestational drive, i.e. selective miscarriage of fetuses who have not inherited the haplotype from a heterozygous mother. Recurrent pregnancy loss (RPL) is defined as three or more consecutive pregnancy losses....... The objective was to test the gestational drive theory for the 8.1AH in women with RPL and their live born children. METHODOLOGY: We investigated the inheritance of the 8.1AH from 82 heterozygous RPL women to 110 live born children. All participants were genotyped for HLA-A, -B and -DRB1 in DNA from EDTA......-treated blood or buccal swaps. Inheritance was compared with a Mendelian inheritance of 50% using a two-sided exact binomial test. RESULTS: We found that 55% of the live born children had inherited the 8.1AH, which was not significantly higher than the expected 50% (P = 0.29). Interestingly, we found a non...

To assess the association between maternal caffeine intake and risk of pregnancy loss using a systematic review and meta-analysis. Categorical and dose-response meta-analysis of prospective studies. Relevant articles were identified by searching MEDLINE and SCOPUS databases through 30 January 2015. Two authors independently extracted information from eligible studies. Random-effects models were used to derive the summary relative risks (RR) and corresponding 95% CI for specific categories of caffeine consumption and for a continuous association using generalized least-squares trend estimation. A total of 130 456 participants and 3429 cases in fourteen included studies. Compared with the reference category with no or very low caffeine intake, the RR (95% CI) of pregnancy loss was 1·02 (0·85, 1·24; I(2)=28·3%) for low intake (50-149 mg/d), 1·16 (0·94, 1·41; I 2=49·6%) for moderate intake (150-349 mg/d), 1·40 (1·16, 1·68; I(2)=18·6%) for high intake (350-699 mg/d) and 1·72 (1·40, 2·13; I(2)=0·0%) for very high intake (≥ 700 mg/d). In the dose-response analysis, each 100 mg/d increment in maternal caffeine intake (~1 cup of coffee) was associated with 7% (95% CI 3%, 12%) higher risk of pregnancy loss. Our results may have been affected by publication bias, but the association remained significant for the subset of larger studies. Furthermore, adjustment for smoking and pregnancy symptoms may have been incomplete, potentially resulting in residual confounding. Albeit inconclusive, higher maternal caffeine intake was associated with a higher risk of pregnancy loss and adherence to guidelines to avoid high caffeine intake during pregnancy appears prudent.
Full Text Available Abstract Background HIV-infected women, particularly those with advanced disease, may have higher rates of pregnancy loss (miscarriage and stillbirth and neonatal mortality than uninfected women. Here we examine risk factors for these adverse pregnancy outcomes in a cohort of HIV-infected women in Zambia considering the impact of infant HIV status. Methods A total of 1229 HIV-infected pregnant women were enrolled (2001–2004 in Lusaka, Zambia and followed to pregnancy outcome. Live-born infants were tested for HIV by PCR at birth, 1 week and 5 weeks. Obstetric and neonatal data were collected after delivery and the rates of neonatal ( Results The ratio of miscarriage and stillbirth per 100 live-births were 3.1 and 2.6, respectively. Higher maternal plasma viral load (adjusted odds ratio [AOR] for each log10 increase in HIV RNA copies/ml = 1.90; 95% confidence interval [CI] 1.10–3.27 and being symptomatic were associated with an increased risk of stillbirth (AOR = 3.19; 95% CI 1.46–6.97, and decreasing maternal CD4 count by 100 cells/mm3 with an increased risk of miscarriage (OR = 1.25; 95% CI 1.02–1.54. The neonatal mortality rate was 4.3 per 100 increasing to 6.3 by 70 days. Intrauterine HIV infection was not associated with neonatal morality but became associated with mortality through 70 days (adjusted hazard ratio = 2.76; 95% CI 1.25–6.08. Low birth weight and cessation of breastfeeding were significant risk factors for both neonatal and early mortality independent of infant HIV infection. Conclusions More advanced maternal HIV disease was associated with adverse pregnancy outcomes. Excess neonatal mortality in HIV-infected women was not primarily explained by infant HIV infection but was strongly associated with low birth weight and prematurity. Intrauterine HIV infection contributed to mortality as early as 70 days of infant age. Interventions to improve pregnancy outcomes for HIV-infected women are needed to

To evaluate changes during the development of proteinuria, podocyte morphology and protein expression were evaluated in spontaneously proteinuric, Dahl salt-sensitive (Dahl SS) rats. Dahl SS rats on a low-salt diet were compared with spontaneously hypertensive rats (SHR) at age 2, 4, 6, 8, and 10 weeks. Blood pressure, urinary protein excretion, urinary albumin excretion, and podocyte morphology were evaluated. In addition, the expression of 11 podocyte-related proteins was determined by analyzing protein and mRNA levels. In Dahl SS rats, proteinuria became evident around week 5, increasing thereafter. SHR rats remained non-proteinuric. Dahl SS rats showed widespread foot process effacement at 10 weeks. At ≤8 weeks, expression and distribution of the podocyte proteins was similar between the two strains, except for the protein podoplanin. At 4 weeks, podoplanin began decreasing in the glomeruli of Dahl SS rats in a focal and segmental fashion. Podoplanin loss increased progressively and correlated with albuminuria (r = 0.8, P < 0.001). Double labeling experiments revealed increased expression of the podocyte stress marker desmin in glomerular areas where podoplanin was lost. Dahl SS rats did not show podoplanin gene mutations or decreased mRNA expression. Thus, podocyte morphology and the expression and distribution of most podocyte-specific proteins were normal in young Dahl SS rats, despite marked proteinuria. Our study suggests that decreased expression of podoplanin plays a role in the decrease of glomerular permselectivity. PMID:18599604

Permanent first molars (PFM) with a poor prognosis are routinely extracted in children throughout the United Kingdom. National guidelines suggest that to achieve spontaneous closure for the mandibular arch, the PFM should be extracted at 8 to 10 years of age, during bifurcation formation of the second molar. The literature is of limited quality and has suggested alternative variables that may be associated with successful space closure. Our aim was to investigate the radiographic prognostic factors associated with space closure after extraction of PFM. Two objectives of the research are reported in this article: to determine factors that might predict space closure of the second molar after extraction of the PFM, and to develop a tool kit to aid clinical decision making. We assessed 148 maxillary and 153 mandibular PFM extracted from 81 participants retrospectively. Dental age, second molar developmental stage, second premolar and second molar angulations, and presence or absence of the third molar were assessed on the preextraction orthopantomograms. Outcome was assessed via visual examination, study models, or radiographs. Closure occurred in 89.9% of the maxillary and 49.0% of the mandibular quadrants. Dental age was statistically, but not clinically, significant in the maxillary arch (P space closure. The developed tool kit requires further validity testing.

This study examined the prevalence of and changes in loss of control over eating (LOC) among pregnant women with overweight/obesity, along with associations between LOC and depressive symptoms and stress. Community women (N = 200; body mass index ≥ 25; 12-20 weeks gestation) reported LOC before and during early pregnancy using the Eating Disorder Examination, which was adapted for administration in pregnancy. Women self-reported depressive symptoms and stress during early pregnancy. Twenty-eight percent (n = 56) of women reported LOC before or during early pregnancy: 14.5% (n = 29) reported LOC incidence during early pregnancy, 9.5% (n = 19) reported LOC persistence from prepregnancy to early pregnancy, and 4.0% (n = 8) reported LOC prepregnancy only. Women with LOC reported more depressive symptoms and stress than did those without. Women with LOC persistence reported clinically significant depressive symptoms and elevated stress. Levels of depressive symptoms and stress differed between women with LOC persistence and those without LOC (ps women with LOC, few reported remission, but one-half reported onset during early pregnancy. Longitudinal studies are needed among mothers with overweight/obesity to identify patterns of LOC throughout pregnancy and how LOC affects perinatal outcomes. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:582-586). © 2016 Wiley Periodicals, Inc.

Recurrent pregnancy loss (RPL) is defined by two or more failed pregnancies. The relation between RPL and inherited thrombophilia requires anticoagulant therapy during pregnancy. However the obstetric outcomes have not been well defined in these RPL patients diagnosed with inherited thrombophilia, who have been given anticoagulant therapy. To investigate the obstetric outcomes in pregnant women with RPL who are given low molecular weight heparin (LMWH) and low-dose aspirin due to diagnosis of inherited thrombophilia. A hundred and eight RPL women were diagnosed with inherited thrombophilia, and 98 women were diagnosed with unexplained RPL. The patients with inherited thrombophilia were given LMWH and low-dose aspirin. Unexplained RPL patients were not given any medicine. The obstetric outcomes of participants were noted. In thrombophilic group, the live-birth levels were significantly higher [90 (83%) vs 67 (68%) p < 0.05], and the miscarriage levels were significantly lower than that in the control group [14 (13%) vs 27 (28%) p < 0.01]. The number of patients with preeclampsia was significantly higher in the thrombophilic group [16 (15%) vs 6 (6%) p < 0.05]. The number of preterm births was significantly higher than that of the controls [25 (23%) vs 10 (10%) p < 0.05]. The median gestation age of delivery was 35 weeks for thrombophilic patients and 38 weeks for controls (p < 0.05). The RPL patients diagnosed with inherited thrombophilia and who were given LMWH with low-dose aspirin had higher live-birth rates and lower miscarriage rates than those in the unexplained RPL patients. Increased risk of preeclampsia is seen in RPL patients with inherited thrombophilia despite thrombophilia prophylaxis.

We investigated the expression of methyl transferase G9a and methylated histone H3-K9 in fresh human decidual/endometrial tissue of 12 normal early pregnancies and 15 unexplained recurrent spontaneous abortions (URSA). The samples were obtained through dilatation and curettage and collected as per strict inclusion-exclusion criteria. The tissue was subjected to immunohistochemical analysis (IHC), western blotting (WB) and RT-PCR analysis. The results demonstrated methyl transferase G9a to have a lower expression in abortions when compared with that in normal pregnancy (P K9 was significantly lower (P < 0.0001) in URSA tissues than in controls. This study suggests that methylation may cause URSA and indicates the need for further work to explore the role of methylation in URSA and its possible prevention through locally acting methylating/demethylating agents.

Full Text Available Risk of procedure-related pregnancy loss is currently widely quoted in the UK as 1% for amniocentesis and 1.5% for chorionic villus sampling. Published data suggest that these risk figures are out of date and inaccurate, and that new guidelines are required for pre-test counseling. It is our opinion that accurate and evidence-based information concerning miscarriage risk is vital when counseling women, as exaggeration of this risk may deter women from testing, or cause unjustified remorse if a miscarriage ensues. It is also essential that health-care economists are aware of the up-to-date evidence on “procedure-related risk” when applying risk-benefit analysis to assess new technology for non-invasive screening.

Full Text Available X-chromosome inactivation (XCI is a phenomenon that occurs in female mammals. Typically, maternally- and paternally-derived X chromosomes are inactivated at approximately the same frequency. If preferential inactivation occurs, the person is considered to have skewed XCI. Skewed XCI has been reported to occur more frequently in women who experience recurrent pregnancy loss (RPL. In this study, we sought to investigate if there is an association between skewed XCI and unexplained RPL in Taiwanese women. A total of 194 women who had experienced unexplained RPL were recruited into the study. Human androgen receptor or DXS6673E and DX15-134 loci were used in the XCI assay. The results of our study suggested that a cut-off point 95% XCI is associated with RPL. Extremely skewed XCI occurs in a subset of Taiwanese women with RPL.

Hereditary thrombophilia (HT) screening is performed as routine work-up of recurrent pregnancy loss (RPL) in Pakistan. In Northern Pakistan the prevalence of HT is not known. HT is not detected in the majority of RPL cases, especially in patients with ≤ 3 pregnancy losses (PL). The aim of this study was to determine the frequency of HT in women with RPL, and to find the prevalence of HT in patients with ≤ 3 PL and > 3 PL. Lupus-anticoagulant-negative patients with unexplained RPL were screened for protein C, protein S, antithrombin, and factor V Leiden. A total of 315 patients with RPL were screened and 13 (4%) had evidence of HT. Protein C and protein S deficiency were detected in 6/140 (4.3%) women with > 3 PL and in 2/175 (1.1%) women with ≤ 3 PL. Antithrombin deficiency was detected in 2/140 (0.75%) women with > 3 PL and in no patients with ≤ 3 PL. Factor V Leiden was detected in 3/26 (12%) women with > 3 PL and in no patients with ≤ 3 PL. The prevalence of HT in patients with >3 PL was significantly higher than in patients with ≤ 3 PL (P = 0.002). We detected a strong association between HT and >3 PL (odds ratio 7.3; 95% confidence interval: 1.60-33.85) as compared to ≤ 3 PL. HT was detected in 4% of patients with RPL. The prevalence of HT in patients with > 3 PL is significantly higher than in patients with ≤ 3 PL. © 2014 The Authors.

Full Text Available BACKGROUND: 15% of reproducing couples suffer from pregnancy loss(PL and recurs in 2-3%. One of the most frequently hypothesized causes of unexplained PL refers to a defective maternal haemostatic response leading to uteroplacental thrombosis. Hereditary thrombophilia and antiphospholipid antibodies have been extensively described as risk factors for PL in women with unknown aetiology. Recently, a new marker has emerged: the cell-derived procoagulant circulating microparticles(MPs which have been reported to have a major role in many thrombosis complicated diseases. This study aims to analyze the significance of procoagulant MPs in women suffering from unexplained recurrent pregnancy loss(RPL, and characterize their cellular origin. METHOD AND FINDINGS: 115 women with RPL were analyzed for common thrombophilia markers and different cell derived MPs-total annexinV, platelet(CD41a, endothelial(CD146,CD62e, leukocyte(CD45, erythrocyte(CD235a and tissue factor(CD142(TF expressing MPs and were compared with 20 healthy non-pregnant women. Methodology for MP analysis was standardized by participating in the "Vascular Biology Scientific and Standardization Committee workshop". RESULTS: Total annexinV, TF and endothelial MPs were found significantly increased(p<0.05, 95% confidence interval in women with RPL. The procoagulant activity of MPs measured by STA-PPL clotting time assay was found in correspondence with annexinV MP levels, wherein the clot time was shortened in samples with increased MP levels. Differences in platelet, leukocyte and erythrocyte derived MPs were not significant. Thirty seven of 115 women were found to carry any of the acquired or hereditary thrombophilia markers. No significant differences were seen in the MP profile of women with and without thrombophilia marker. CONCLUSION: The presence of elevated endothelial, TF and phosphatidylserine expressing MPs at a distance (at least 3 months from the PL suggests a continued chronic

Acute pancreatitis in pregnancy (APIP) poses a serious threat to the mother and her fetus, and might lead to fetal loss including miscarriage and stillbirth in certain patients. We sought to identify possible factors that affect fetal distress and evaluated outcomes of patients with APIP.We retrospectively reviewed clinical records of 54 pregnant women with APIP, who were treated at 2 tertiary clinical centers over a 6-year period. Clinical characteristics including etiology and severity of APIP, fetal monitoring data, and maternofetal outcomes were analyzed.Etiology of APIP included acute biliary pancreatitis (ABP, n = 14), hyperlipidemic pancreatitis (HLP, n = 22), and other etiologies (n = 18). Severity was classified as mild acute pancreatitis (MAP, n = 23), moderately severe acute pancreatitis (MSAP, n = 24), and severe acute pancreatitis (SAP, n = 7). The incidence of preterm delivery, fetal distress, and fetal loss increased with the progression of severity of APIP (P < .05). The severity of HLP was significantly higher than that of ABP and APIP of other etiology (P < .01). HLP was more likely to lead to fetal distress than other APs (P < .01). Only 12 (22.2%) patients had fetal monitoring including non-stress test (NST); 1 case of SAP (14.3%) and 15 cases of MSAP (62.5%) were not transferred to intensive care unit for intensive monitoring.The incidence of fetal distress and fetal loss increased with worsening of APIP severity. HLP tends to result in worse fetal outcomes. The deficiencies of fetal state monitoring, lack of assessment, and management of pregnant women might increase the fetal loss in APIP.

The T-cell receptor CD3 (TCR/CD3) complex plays a central role in antigen recognition and activation of mature T cells, and therefore abnormalities in the expression of the complex should induce unresponsiveness of T cells to antigen stimulus. Using flow cytometry, we detected and enumerated variant cells with loss or alteration of surface TCR/CD3 expression among human mature CD4 + T cells. The presence of variant CD4 + T cells was demonstrated by isolating and cloning them from peripheral blood, and their abnormalities can be accounted for by alterations in TCR expression such as defects of protein expression and partial protein deletion. The variant frequency in peripheral blood increased with aging in normal donors and was highly elevated in patients with ataxia telangiectasia, an autosomal recessive inherited disease with defective DNA repair and variable T-cell immunodeficiency. These findings suggest that such alterations in TCR expression are induced by somatic mutagenesis of TCR genes and can be important factors related to age-dependent and genetic disease-associated T-cell dysfunction.

This study compared the accuracy of ultrasound cervical assessment (cervical length and cervical index) and digital examination (Bishop score and cervical score) in the prediction of spontaneous birth before 34 weeks in twin pregnancies. In a prospective multicenter study, digital examination and transvaginal sonography were performed consecutively in twin pregnancies attending for routine sonography at either 22 weeks (175 women) or 27 weeks (153 women). The digital examination took place first, and the Bishop score and cervical score (cervical length minus cervical dilatation) were calculated. Ultrasound measurements were then made of cervical length and funnel length to yield the cervical index (1 + funnel length/cervical length). The association between each variable and delivery before 34 weeks was tested by the Mann-Whitney U-test. The receiver-operating characteristics (ROC) curves of the ultrasound and digital indicators were determined for both gestational age periods, and the areas under the ROC curves compared. The best cut-off values for each indicator were used to determine predictive values for delivery before 34 weeks. The median gestational age at delivery among the women included in the 22-week examination period was 36.0 (range, 21-40) weeks; 10.9% (19) gave birth spontaneously before 34 weeks. The median cervical length was 40 (range, 6-65) mm. All four parameters were predictors of delivery before 34 weeks. The areas under the ROC curves for cervical index, cervical length, Bishop score and cervical score did not differ significantly. The median gestational age at delivery among the women in the 27-week examination period was 36.0 (range, 27-40) weeks; 9.2% (14) gave birth spontaneously before 34 weeks. The median cervical length was 35 (range, 1-57) mm. All parameters except the Bishop score were predictors of delivery before 34 weeks. The likelihood ratio of the positive and negative tests for cervical length digital examination at the 27-week

Human chorionic gonadotropin (hCG) is a glycoprotein hormone, secreted by the syncytiotrophoblast cells of the fertilized ovum, that enters the maternal circulation at the time of endometrial implantation. It is composed of two nonidentical subunits; α and β, with molecular weights of 14 kD and 23 kD, respectively. Human chorionic gonadotropin binds to the same receptor as hLH and displays the same biological response, namely, to stimulate the declining function of the corpus luteum to produce progestins and estrogen late in the menstrual cycle. The differences in the structures of hCG and hLH have been exploited to develop antibodies that can measure hCG specifically in the presence of hLH. Two-site antibody binding assays have been developed, based on a surface immunological concept of hCG epitopes, that involve four distinct regions to which antibodies against hCG can bind simultaneously. Antibody cooperative effects, in conjunction with kinetic advantages derived from the concentration factors by use of the sandwich assay technique (immunoradiometric assay, IRMA), have enabled development of extremely sensitive and specific measurement protocols for urinary hCG. The assay described herein permits the detection of pregnancy on an average 25.4 days after the first day of the preceding menses, as opposed to 29.5 days for conventional radioimmunoassay techniques. In addition, the greater sensitivity and specificity of this assay method has permitted the detection of episodes of fetal loss not detected by radioimmunoassay of urine specimens. A large scale epidemiological study is in progress using this assay technique as a way to identify pregnancies that are lost before becoming clinically apparent

Presynchronization of cows with 2 injections of prostaglandin administered 14d apart (Presynch-Ovsynch) is a widely adopted procedure to increase pregnancy per artificial insemination (P/AI) for the first service. In a Presynch-Ovsynch protocol, 2 different management strategies can be observed. Either all cows receive timed artificial insemination (onlyTAI) or cows detected in estrus after the second PGF2α injection are inseminated and the remaining cows without signs of estrus will be subject to timed AI (EDAI+TAI). A systematic review of the literature was performed with the objective to evaluate the effect of insemination after estrous detection during a Presynch-Ovsynch protocol for the first service on fertility in lactating dairy cows. Two statistical approaches were conducted using either a fixed or a random effects meta-analysis based on the heterogeneity among the experimental groups. Reproductive outcomes of interest were P/AI measured on d32 (d 28 to 42) and pregnancy loss between d32 and 60 (d 42 to 74) of gestation. In approach 1, 3 randomized controlled studies including 1,689 cows with the primary objective to evaluate the effect of insemination after estrous detection in a Presynch-Ovsynch protocol were used. The incorporation of insemination after estrous detection decreased the odds of pregnancy by 35% [odds ratio=0.65; 95% confidence interval (CI)=0.53-0.80] on d32 after AI using a fixed effects model. We detected no effect on pregnancy loss on d60 of gestation (odds ratio=0.88; 95% CI=0.55-1.43). There was no heterogeneity among the 3 studies regarding P/AI and pregnancy loss. In approach 2, cows from approach 1 and cohorts from another 17 experimental groups including 8,124 cows submitted to first AI using a Presynch-Ovsynch protocol were used. Information regarding pregnancy loss was available for 5,200 cows. In the random effects model, the overall proportion of P/AI was 30.9% (95% CI=26.71-35.28; n=2,400) and 41.7% (95% CI=39.76-42.01; n=7

Therapeutic practices in equine reproductive medicine have dramatically evolved over the last 20 years but current usage is not described. The aims of this study were to provide a description of medication use and clinical findings of reproductive examinations alongside measures of reproductive efficiency in thoroughbreds. A prospective cohort study was conducted in the 2013 and 2014 breeding seasons. Mare and stallion details, information on veterinary interventions and findings of reproductive ultrasound scans were collected using questionnaires and entered into a custom-designed Microsoft Access database. Descriptive summary statistics were derived directly from the database and using Microsoft Excel. Information was collected from 2246 pregnancies in 1754 mares from 29 stud farms. Ovulatory induction agents were used in 91.8% of cases, oestrus induction agents in 38.4% and covering therapies in 62.7%. Intrauterine antimicrobials were used in 49.6% of mares. Single pregnancies accounted for 83.9% of pregnancies, twins for 15.3% and triplets for 0.7%. The overall incidence of pregnancy loss between days 15-42 was 6.4% (95% CI 5.4%, 7.4%) and 1.6% (95% CI 1.1%, 2.1%) between days 43-65. A further 1.3% of pregnancies were lost by October and 4.5% by birth (including stillbirths). Eighty-three percent of all pregnancies resulted in a live foal. In conclusion, there has been a considerable increase in the use of reproductive therapeutics over the last 12 years. Nonetheless, incidence of pregnancy loss and live foal percentages remain essentially unchanged. Risk factor studies are required to determine if the substantial increase in therapeutic usage is conferring positive benefits. Copyright © 2017 Elsevier B.V. All rights reserved.

We report a case of a 36-year old patient with prior history of thrombosis in a setting of antiphospholipid antibody syndrome (APS) as well as pregnancy-associated catastrophic antiphospholipid syndrome (CAPS), resulting in multi-organ infarction and pregnancy loss. The episode of CAPS occurred while she was receiving antepartum low-dose aspirin and therapeutic-dose enoxaparin. This patient presented again at 6 weeks gestation and ultrasounds were consistent with fetal growth restriction, concerning for placental insufficiency and thrombosis. This time, hydroxychloroquine and monthly intravenous immunoglobulin (IVIG) infusions were added to her prophylaxis regimen, resulting in a successful delivery. Platelet count and antiphospholipid antibody titers were routinely monitored throughout pregnancy as markers of disease activity for APS. Current thromboprophylaxis guidelines do not address therapeutic options to prevent further pregnancy morbidity in women who develop recurrent episodes of thrombosis or CAPS despite receiving adequate anti-thrombotic treatment. Use of hydroxychloroquine and IVIG has been associated with good outcomes in this subset of patients.

Full Text Available KDM2A is a histone demethylase associated with transcriptional silencing, however very little is known about its in vivo role in development and disease. Here we demonstrate that loss of the orthologue kdm2aa in zebrafish causes widespread transcriptional disruption and leads to spontaneous melanomas at a high frequency. Fish homozygous for two independent premature stop codon alleles show reduced growth and survival, a strong male sex bias, and homozygous females exhibit a progressive oogenesis defect. kdm2aa mutant fish also develop melanomas from early adulthood onwards which are independent from mutations in braf and other common oncogenes and tumour suppressors as revealed by deep whole exome sequencing. In addition to effects on translation and DNA replication gene expression, high-replicate RNA-seq in morphologically normal individuals demonstrates a stable regulatory response of epigenetic modifiers and the specific de-repression of a group of zinc finger genes residing in constitutive heterochromatin. Together our data reveal a complex role for Kdm2aa in regulating normal mRNA levels and carcinogenesis. These findings establish kdm2aa mutants as the first single gene knockout model of melanoma biology.

Herein, we report the first case of successful term delivery of twins in a patient with bicorporeal septate uterus via natural conception. The patient had been diagnosed with complete septate, didelphys and bicornuate uterus during different phases of her three pregnancies. Based on follow-up data at six weeks and then six months post-partum of the last pregnancy, we found that the abnormalities presented in our case did not fit the criteria of any categories following American Fertility Society and European Society of Human Reproduction and Embryology-European Society for Gynaecological Endoscopy classification systems. After comprehensive review of the uterine morphologic characteristics, embryology and pregnancy outcome, we considered 'bicorporeal septate uterus' the most appropriate diagnosis. This case emphasized the atypical changes of uterine shape as twin pregnancy advances and its influence on productive performance and pregnancy outcome in uterine malformation. It also raised concern regarding the usability and comprehensiveness of the two most popular classification systems. © 2016 Japan Society of Obstetrics and Gynecology.

To evaluate the role of cervical length (CL) and uterine artery pulsatility index (UtA-PI) at 11+0 to 13+6 weeks as predictors of spontaneous preterm delivery (sPTD) in a Chilean population. This was a prospective study of asymptomatic women with singleton pregnancies attending for a nuchal translucency scan at 11+0 to 13+6 weeks' gestation and who underwent a transvaginal scan for evaluation of CL and UtA-PI. Exclusion criteria were fetal and pregnancy complications (other than sPTD) and iatrogenic delivery atUtA-PI were adjusted for fetal crown-rump length and maternal characteristics and expressed as multiples of the median (MoM) of the unaffected group. Prediction of sPTD using maternal and pregnancy characteristics was studied using logistic regression analysis. A total of 3480 women were recruited into the study and, after application of exclusion criteria, 3310 were included in the analysis. The rate of sPTD atUtA-PI between pregnancies with and without subsequent sPTD. Logistic regression analysis showed that smoking and previous PTD were significantly associated with sPTD atUtA-PI nor CL during the first trimester was shown to be a useful predictor of early sPTD. However, a combined model that includes smoking and previous PTD predicts approximately one-quarter of those women destined to deliver at<34 weeks, with a false-positive rate of 8%.

Omalizumab has been recently approved for treating patients with refractory to H1- antihistamines chronic spontaneous urticaria (CSU). Although hair loss is listed among omalizumab side effects, there are no available data to estimate its frequency. We describe for the first time hair loss as a side effect associated with omalizumab administration in three women, 38, 62 and 70 years old, suffering from refractory to H1-antihistamines CSU. This information was retrieved from their Chronic Urticaria Quality of Life Questionnaires. Despite this side effect, all patients agreed to continue omalizumab regular administration. Hair loss appeared to be transient, lasting up to four months. All cases finally benefited from omalizumab continuation.

Full Text Available A case of a 19-year-old female with class U3b/C2/V1 uterus conceived a twin pregnancy with a fetus in each horn after spontaneous conception. She referred to our department with presentation of premature rupture of membranes, with a history of cesarean delivery of a single full term living fetus a year and a half before this delivery. Examination revealed two completely separate uterine horns with a fetus in each horn, two distinct externally rounded cervices, and a single vagina with a short nonobstructing vaginal septum in the upper part of the vagina. And as the appropriate mode of delivery is still unclear, each case should be managed as the condition requires, and in our case urgent bilateral caesarean sections were performed.

We assessed the association between the timing of pregnancy with the risk of postpartum virologic failure and loss from HIV care in South Africa. 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. 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. 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. 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.

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

To compare the levels of IgG and IgM anti beta-2 glycoprotein I antibodies and IgG and IgM anti prothrombin antibodies among women with unexplained recurrent pregnancy losses and women with at least 2 live issues. To compare the prevalence of newer anti beta-2 glycoprotein I & anti prothrombin antibodies with conventional Lupus anticoagulant & anticardiolipin antibodies. 50 women with recurrent pregnancy losses & 50 matched controls were evaluated for the presence of: Lupus anticoagulant-screened by LA sensitive aPTT& DRVV and confirmatory Staclot Assay. ELISA kits were used for detecting IgG & IgM anticardiolipin, anti beta-2 glycoprotein I & anti prothrombin antibodies. 11/50 (22 %) women in study group and none in control group had circulating antiphospholipid antibodies. 2 cases (4 %) had lupus anticoagulant. 1 case (2 %) had anticardiolipin antibody & 6 cases (12 %) were positive for anti beta-2 Glycoprotein I antibody (p value = 0.027). 3 cases (6 %) had anti prothrombin antibody. All were mutually exclusive except for one. Women with recurrent pregnancy losses should be tested for anti beta-2 Glycoprotein I antibodies & anti prothrombin antibodies in addition to conventional lupus anticoagulant and anticardiolipin antibodies. This approach can decrease the incidence of SNAP (seronegative antiphospholipid syndrome) cases while establishing the true prevalence of antiphospholipid syndrome.
Full Text Available Background & Aim: Air pollution has been one of the threatening factors of human health during the last century. Particulate matters are the major air pollutants in urban areas. The aim of this study was to determine the effect of ambient particulate mattes on spontaneous abortion. Methods: This case-control study was conducted between June 2010 to February 2011 on 148 spontaneous abortion (case group and 148 pregnant women (control group in Tehran. From 22 regions of Tehran, 10 hospitals were randomly selected and samples were collected by simple random sampling from these hospitals. The mean of particulate matters was obtained from monitoring stations of Tehran Air Quality Control Company (TAQCC. Collected data was analyzed by the SPSS software using independent sample t-test, chi-square test, multiple and linear regression models. Results: Two groups in the study were matched in participants' age, husbands' age, age at first childbirth, educational level, family average income, previous type of delivery and the interval between deliveries, any previous abortion experience, body mass index, parity, duration of residence in Tehran and the amount of time spent at work and outside of home (P>0.05. On analyzing the collected data, it was revealed that the mean of ambient PM10 concentration in case group (94.4±39.22 micro gr/m3 was significantly higher than the control group (83.54±22.55 micro gr/m3 in T-test (P<0.001 and also the rate of abortion was higher in these areas (OR: 1.01, CI95%: 1.003-1.018. For assessing the relationship between gestational age and ambient PM10 concentration, linear regression method was used. Results indicated that there was a negative correlation between these variables. Conclusion: Findings of this study showed that there was a significant relationship between occurrence of spontaneous abortion and the ambient PM10 concentration.

We have recently shown that serum relaxin-2 levels are attenuated in women with a history of recurrent pregnancy loss (RPL). We sought to determine whether a history of RPL is also associated with changes in serum matrix metalloproteases (MMPs) and tissue inhibitors of matrix metalloproteases (TIMP) -1 and -2. We obtained serum from 20 pregnant women with a history of RPL and 20 age-matched pregnant women with no history of RPL (NRPL) at 6-8, 10-12, 20, and 34 weeks gestation, and from cord blood. We quantified total serum concentrations of MMP-1, MMP-3, MMP-9 and TIMP-1 and TIMP-2 by ELISA. We determined whether these serum marker levels were associated with a history of RPL and delivery before 37 weeks gestation. There was no difference in the rates of miscarriage, preterm birth or prelabour rupture of fetal membranes between RPL and NRPL. However babies born to RPL were lighter than those born to NRPL. Serum MMP-1, 9, and TIMP-1 did not differ between RPL and NRPL but MMP-3 was higher in RPL vs. NRPL at 6-8 weeks (P history of RPL than either peptide separately - area under the ROC curves for RLX-2 0.79 (95% CI 0.57 to 0.92), TIMP-2 0.83 (95% CI 0.63 to 0.95), and for RLX-2:TIMP-2 ratio 0.92 (95% CI 0.74 to 0.99). Women with a history of RPL demonstrate increased serum TIMP-2 and reduced RLX-2 during a subsequent viable pregnancy. Determination of both markers in early pregnancy enhances the discrimination of women with a history of RPL. These observations suggest roles for these two peptides in early implantation and placental development. Whether these may prove to be reliable early predictive markers for subsequent pregnancy loss in the index pregnancy is unknown and will require further studies.

Numerous studies have documented the negative effects of maternal alcohol consumption during pregnancy on risk of pregnancy loss, yet whether prepregnancy alcohol intake affects the risk of spontaneous abortion is still unclear. This study aimed to assess prepregnancy alcohol intake and risk of spontaneous abortion and stillbirth. Our prospective cohort study included 27,580 pregnancies reported by 17,929 women in the Nurses' Health Study II between 1990 and 2009. Alcohol intake was assessed in 1989 and 1991 and every 4 y thereafter with the use of a validated questionnaire. Women were classified into 5 categories of consumption: 0, 0.1-1.9, 2-4.9, 5-9.9, and ≥10 g/d (1 serving = ∼12 g). Pregnancies were self-reported, with case pregnancies lost spontaneously (spontaneous abortion after gestation of abortion). Multivariable log-binomial regression models with generalized estimating equations were used to estimate RRs and 95% CIs. Incident spontaneous abortion and stillbirth were reported in 4326 (15.7%) and 205 (0.7%) pregnancies, respectively. Prepregnancy alcohol intake was not associated with spontaneous abortion. Compared with women who did not consume alcohol, the multivariable RRs (95% CIs) for increasing categories of alcohol intake among women who did consume alcohol were 1.04 (0.97, 1.12) for 0.1-1.9 g/d, 1.02 (0.94, 1.11) for 2-4.9 g/d, 1.01 (0.92, 1.10) for 5-9.9 g/d, and 0.98 (0.88, 1.09) for ≥10 g/d (P-trend = 0.45). Women who consumed ≥2 servings beer/wk before pregnancy had a 9% (95% CI: 1%, 17%) lower risk of spontaneous abortion than did women who consumed spontaneous abortion. Total alcohol and specific alcohol beverage intake before pregnancy were not associated with stillbirth. Prepregnancy alcohol intake was not related to risk of incident spontaneous abortion or stillbirth in women with no history of pregnancy loss. Our results provide reassuring evidence that low to moderate alcohol intake (≤12 g/d) before pregnancy initiation does

To evaluate prospectively the relationship between prepregnancy folate intake and risk of spontaneous abortion and stillbirth. Women in the Nurses' Health Study II who self-reported a pregnancy between 1992 and 2009 were included in this analysis. Dietary folate and supplement use was assessed every 4 years, starting in 1991, by a food frequency questionnaire. Pregnancies were self-reported with case pregnancies lost spontaneously (spontaneous abortion less than 20 weeks of gestation and stillbirth 20+ weeks of gestation) and comparison pregnancies ending in ectopic pregnancy, induced abortion, or live birth. Among the 11,072 women, 15,950 pregnancies were reported of which 2,756 (17.3%) ended in spontaneous abortion and 120 (0.8%) ended in stillbirth. Compared with women in the lowest quintile of prepregnancy folate intake (less than 285 micrograms/d), those in the highest quintile (greater than 851 micrograms/d) had a relative risk of spontaneous abortion of 0.91 (95% confidence interval [CI] 0.82-1.02) after multivariable adjustment (P trend=.04). This association was primarily attributable to intake of folate from supplements. Compared with women without supplemental folate intake (0 micrograms/d), those in the highest category (greater than 730 micrograms/d) had a relative risk of spontaneous abortion of 0.80 (95% CI 0.71-0.90) after multivariable adjustment (P trend spontaneous abortion was consistent across gestational period of loss. A similar inverse trend was observed with the risk of stillbirth, which fell short of conventional significance (P trend=.06). Higher intake of folate from supplements was associated with reduced risk of spontaneous abortion. Women at risk of pregnancy should use supplemental folate for neural tube defect prevention and because it may decrease the risk of spontaneous abortion. : II.

Full Text Available Objective: The study aims to state the effectiveness of a new combination treatment composed of folic acid, doxycycline, low dose aspirin and natural progesterone in cases of recurrent early pregnancy loss. Study design: A clinical comparative hospital-based study. Setting: Women Health Hospital – Assiut University – Egypt. Materials and methods: All patients with recurrent early pregnancy loss at 10 weeks or less attending our antenatal care unit were included. The patients were recruited over a period of 16 months and allocated into two groups. The study group received a regimen of folic acid, doxycycline, aspirin, and progesterone. The control group did not receive the previous regimen in the proposed way. The main outcome measures the live birth rate and complications of pregnancy in both groups. Results: Three hundred patients were recruited, with 150 women in each group. A high rate of live births was found in the study group (76.0% more than the control group (59.3%. Women in the Control Group reported more complications (76.0% vs. 51.3%. These were mainly abortion (40.0% vs. 23.3%, pre-eclampsia (16.0% vs. 10.7% and oligohydramnios (10.0% vs. 6.7%. Conclusion: The implementation of combination treatment of folic acid, doxycycline, low dose aspirin and natural progesterone resulted in a significant increase in the live birth rate, a significant reduction in miscarriages, and lower incidence of complications in patients with recurrent early pregnancy loss.

A substantial proportion of the etiology involved in female infertility and adverse pregnancy outcomes remains idiopathic. Recent scientific research has suggested a role for environmental factors in these conditions. Secondhand tobacco smoke (STS) contains a number of known or suspected reproductive toxins, and human exposure to STS is prevalent worldwide. Robust evidence exists for the toxic effects of active smoking on fertility and pregnancy, but studies of passive exposure are much more ...

Full Text Available Abstract We report a case of a 26-year-old female, who presented at 34 weeks of an uncomplicated pregnancy with an acute ST elevation anterior wall myocardial infarction. Cardiac catheterization suggested a left main coronary artery dissection with pseudoaneurysm formation. The patient's course was complicated by congestive heart failure. She was initially managed conservatively by a multidisciplinary team including heart failure specialists, obstetricians, and cardiovascular surgeons. 4 days after admission, her LMC was imaged by dual-source 64 slice Cardiac computed tomography, coronary dissection was identified extending to the lumen, and the presence of pseudoaneurysm was confirmed. She underwent subsequently a staged procedure, which included placement of an intra-aortic balloon pump, cesarean section, and coronary artery bypass grafting. This case illustrates the utility of coronary artery CT imaging to assess the complexity and stability of coronary artery dissections, thereby helping to determine the need for, and timing of revascularization procedures.

The aim of the study is to identify HLA-DQA1, HLA-DQB1 allele and to assess the risk of early pregnancy loss of women, couples with reproductive failure in the first trimester of pregnancy in comparison with fertile women, couples. The study group (B) enrolled 61 couples with reproductive failure and the control group (C) enrolled 20 fertile couples with at least 2 children. HLA-DQA1 gene typing was performed using PCR-sequence-specific primer (SSP) on the high resolution level according to established procedure of labeling and using the detection kit (FASTYPE DQASSP Typing, FASTYPE DQA "High Resolution" Typing Sheet) purchased from Bio-Synthesis (USA). In female patient the highest risk quotient was associated with alleles HLA-DQA 01101/0105 OR 7.19 (95% CI 1.18-5.23; p=0.03) and HLA-DQB5 OR 3.67 (95% CI=1.11-12.0; p=0.037). The lowest but statistically significant risk of pregnancy failure in this group was related to allele HLA-DQB6 OR 0.48 (95% CI=0.22-1.04; p=0.087). In patient and control couples the significantly increased risk of pregnancy failure was related to the frequency of HLA-DQB5 allele OR 2.3 (95% CI 1.09-4.82; p=0,035). The lowest risk quotient in the patient couples was associated with HLA-DQ 0302/0303 allele OR 0.44 (95% CI 0.14-1.36; p=ns). HLA-DQA and HLA-DQB allele might influence pregnancy outcome in the Polish population, but further studies are necessary in this regard.

Women with elevated natural killer (NK) cell frequency and function during pregnancy, suffer from recurrent pregnancy loss (RPL). In the present study, the possible effect of intravenous immunoglobulin (IVIG) administration on Th1 and Th2 cell frequency, cytokine secretion, and expression of transcription factors is compared between RPL patients and control group. Totally, 44 women with a history of RPL (32 women as treated group and 12 as control group) were enrolled in the study. The frequency of Th1 and Th2 lymphocytes, the expression of transcription factors related to these cells and the serum levels of associated cytokines were assessed by flowcytometry, real-time PCR and ELISA, respectively. All, assessments were performed both before and after treatment with IVIG. A significant reduction in Th1 lymphocyte frequency, transcription factor expression and cytokine levels were observed in IVIG-treated group, while all the above parameters indicated a significant increase for Th2 lymphocytes. Th1/Th2 ratio decreased significantly (p value<0.0001) at the end of treatment and 28 out of 32 (87.5%) women in IVIG-treated group had live birth in comparison with 5 out of 12 (41.6%) in untreated group. IVIG administration proves to be an efficient therapeutic strategy which is able to enhance the success rate of pregnancy through a shift in Th2 responses. Furthermore, IVIG presents efficacy for the treatment of reproduction failures especially in subjects with immune cell abnormalities and increased NK cell level and function.

We investigated population-based vital records of the seventeenth and eighteenth century French Canadian population to assess the effects of marriage season on the outcome of the first births under natural fertility conditions (n=21,698 marriages). Promptness of the first successful conception after marriage differed according to marriage season; the proportion of marriages with a marriage-first birth interval of 8.0-10.0 months was lowest (34%) for marriages in August-October (P=0.001). Although the male/female sex ratio of the babies born with an interval of 8.0-10.0 months was generally higher (1.10) than those with an interval of 10.0-24.0 months (1.05), the marriages in August-October resulted in a significantly reduced sex ratio (0.96) among only the prompt conceptions (P=0.026). We discuss whether this seasonal reduction of the sex ratio could be partly explained by a clustered pregnancy loss of male zygotes in early pregnancy.
The retrospective comparative analysis of the following three groups is presented: control group composed of 100 somatically healthy pregnant women; 592 pregnant women with recurrent pregnancy loss complicated with placental dysfunction in the past medical history - the 1st group; and 592 pregnant women with recurrent pregnancy loss without placental dysfunction in the past medical history - the 2nd group. The fetal cardiotocography was analyzed with determination of non-stress test, fetus ultrasound investigation; the fetus biophysical profile was determined; the fates of the current pregnancy and childbearing and the state of the newborn infant were studied; using the statistical analysis, the risk factors affecting the progression of placental dysfunction in women with recurrent pregnancy loss in the past medical history were discovered.

Full Text Available Coal fires, including both underground and coal waste pile fires, result in large losses of coal resources and emit considerable amounts of greenhouse gases. To estimate the annual intensity of greenhouse gas emissions and the loss of coal resources, estimating the annual loss from fire-influenced coal seams is a feasible approach. This study assumes that the primary cause of coal volume loss is subsurface coal seam fires. The main calculation process is divided into three modules: (1 Coal fire quantity calculations, which use change detection to determine the areas of the different coal fire stages (increase/growth, maintenance/stability and decrease/shrinkage. During every change detections, the amount of coal influenced by fires for these three stages was calculated by multiplying the coal mining residual rate, combustion efficiency, average thickness and average coal intensity. (2 The life cycle estimate is based on remote sensing long-term coal fires monitoring. The life cycles for the three coal fire stages and the corresponding life cycle proportions were calculated; (3 The diurnal burnt rates for different coal fire stages were calculated using the CO2 emission rates from spontaneous combustion experiments, the coal fire life cycle, life cycle proportions. Then, using the fire-influenced quantity aggregated across the different stages, the diurnal burn rates for the different stages and the time spans between the multi-temporal image pairs used for change detection, we estimated the annual coal loss to be 44.3 × 103 tons. After correction using a CH4 emission factor, the CO2 equivalent emissions resulting from these fires was on the order of 92.7 × 103 tons. We also discovered that the centers of these coal fires migrated from deeper to shallower parts of the coal seams or traveled in the direction of the coal seam strike. This trend also agrees with the cause of the majority coal fires: spontaneous combustion of coalmine goafs.
Full Text Available Background/AimsOccult HBV infection can persist following HBsAg loss and be transmitted, but the virological features are not well defined.MethodsHere we investigated 25 Korean patients who lost HBsAg during follow up, either spontaneously or subsequent to therapy.ResultsWhereas subtype adr (genotype C was found in 96% of HBsAg positive patients, 75 % of patients who lost HBsAg spontaneously were seemed to be infected with the ayw subtype with sequence similar to genotype D. Mutations in the major hydrophilic region (MHR of HBsAg were found in 7 patients who lost HBsAg spontaneously. The mutations include T123S, M125I/N, C139R, D144E, V177A, L192F, and W196L, some of which have not been reported before. Functional analysis via transfection experiments indicate that the C139R and D144E mutations drastically reduced HBsAg antigenicity, while the Y225del mutation found in one interferon-treated patient impaired HBsAg secretion.ConclusionsLack of detectable HBsAg in patient serum could be explained by low level of ccc DNA in liver tissue, low antigenicity of the surface protein, or its secretion defect.

Anticardiolipin antibodies (aCL) were found to recognize beta 2glycoprotein I (beta 2GPI) structure altered by its interaction with an oxygen modified solid phase surface by gamma-ray radiation. Lupus anticoagulant (LA) has been reported to comprise anti prothrombin antibodies, anti factor X antibodies and anti beta 2GPI antibodies. The present study focuses on the possible association between antibodies against the altered beta 2GPI structure (anti beta 2GPI antibodies) and LA in patients with recurrent pregnancy loss. Moreover, the clinical significance of both subgroups of so-called antiphospholipid antibodies were investigated to cast light on the controversy of whether aCL and LA are risk factors for pregnancy losses. One hundred and ninety five women with a history of two or more unexplained consecutive miscarriages and 100 control pregnant women were tested. Lupus anticoagulant was detected by the dilute phospholipid activated partial thromboplastin time. Anti beta 2GPI antibodies were measured by the ELISA method using commercially oxygenated microtiter plates. Twenty two (11.3%) and 19 (9.7%) of the 195 recurrent aborters were, respectively, positive for LA and anti beta 2GPI antibodies. Seven (3.6%) of the aborters had both of them. None of the control pregnant women had LA. Three of the control pregnant women had anti beta 2GPI antibodies. Nine (40.9%) of 22 aborters with positive-LA had a history of miscarriages in the second trimester as compared to 8 (4.6%) of 173 aborters with negative-LA. (P = 0.000007, Odds ratio = 14.3). None of the 12 aborters with anti beta 2GPI antibodies but no LA had a history of second trimester-fetal loss. These results support the hypothesis that aCL and LA define two distinct but partly related populations and that aCL include two subtypes of antibodies, with and without LA activity. LA and anti beta 2GPI antibodies appear to be associated with pregnancy loss, with LA being linked not only to abortions in the first

Early B-cell factor 1 (EBF1) plays a central role in B-cell lineage specification and commitment. Loss of this critical transcription factor is strongly associated with high-risk, relapsed and therapy-resistant B–cell-acute lymphoblastic leukemia, especially in children. However, Ebf1 haploinsufficient mice exhibit a normal lifespan. To determine whether prolonged survival of B cells would enable tumorigenesis in Ebf1 haploinsufficient animals, we generated Ebf1+/–Bcl-xLTg mice, which express the anti-apoptotic factor Bcl-xL in B cells. Approximately half of Ebf1+/–Bcl-xLTg mice develop aggressive oligoclonal leukemia as they age, which engrafts in congenic wild-type recipients without prior conditioning. The neoplastic cells display a pre-B phenotype and express early developmental- and natural killer cell/myeloid-markers inappropriately. In addition, we found tumor cell-specific loss of several transcription factors critical for maintaining differentiation: EBF1, TCF3 and RUNX1. However, in the majority of tumors, loss of Ebf1 expression was not due to loss of heterozygosity. This is the first spontaneous mouse model of pre-B leukemia to demonstrate inappropriate expression of non-B-cell-specific genes associated with loss of Ebf1, Tcf3 and Runx1 expression. PMID:28692033

Spatial and temporal patterns of vegetal communities control local biogeophysical processes.. The use of cover crops and spontaneous grass cover as a soil erosion control measure is quite common, particularly in hilly agricultural areas. Spontaneous covers show usually irregular spatial and temporal patterns, resulting in a questionable efficiency and and unresolved management requirements. However, due to its zero cost, it is a helpful alternative for soil erosion control in marginal farms (Taguas et al., 2015). The main aim of this work was to characterize the spatial and temporal patterns of spontaneous grass cover in an olive orchard microcatchment to interpret its dependences on other physical features as well as its influence on soil loss control. The specific objectives were: i) to evaluate the relationships between the mean cover and the variables: accumulated precipitation, accumulated evapotranspiration and average minimum temperature for the preceding 5, 15, 30 and 60 days to the sampling date; ii) study the spatial aggregation degree of the cover, its temporal stability and its correlation with different topographical properties, the richness of species and the apparent electrical conductivity as a measure of soil variability; and iii) describe the influence of the cover on runoff and soil loss in the catchments. Cover percentage corresponding to spontaneous grass was evaluated on a seaonsal basis during 3 years (2011-2013), resulting in 12 surveys. A permanent and regular grid of 36 points covering the entire catchment (5-6 samples/ha) was used in each survey. At each location cover percentage was determined through image analyses. In order to explore the relations between cover percentage and meteorological variables, multiple linear regression was applied whereas the SADIE approach (Spatial analysis by distance indices; Perry, 1998) was used to describe possible spatial aggregation patterns and the correlation with features such as aspect, slope

A complete molecular understanding of β-cell mass expansion will be useful for the improvement of therapies to treat diabetic patients. During normal periods of metabolic challenges, such as pregnancy, β-cells proliferate, or self-renew, to meet the new physiological demands. The transcription factor Forkhead box D3 (Foxd3) is required for maintenance and self-renewal of several diverse progenitor cell lineages, and Foxd3 is expressed in the pancreatic primordium beginning at 10.5 d postcoitum, becoming localized predominantly to β-cells after birth. Here, we show that mice carrying a pancreas-specific deletion of Foxd3 have impaired glucose tolerance, decreased β-cell mass, decreased β-cell proliferation, and decreased β-cell size during pregnancy. In addition, several genes known to regulate proliferation, Foxm1, Skp2, Ezh2, Akt2, and Cdkn1a, are misregulated in islets isolated from these Foxd3 mutant mice. Together, these data place Foxd3 upstream of several pathways critical for β-cell mass expansion in vivo. PMID:21952247

The contribution of local inflammation to the pathophysiology of abnormal choromosomally miscarriages remains unclear The objective of this study was to investigate the inflammatory response at the maternofetal interface of women presenting with first trimester miscarriage with abnormal choromosomally Level of TNF-α , IL-6 ve IL-17 were asseyed using immunohistochemistry technique at decidual and placental bed biopsy samples from 23 women with elective termination of pregnancy 21 euploid and 18 aneuploid missed miscarriages. Immunostainig for TNF-α, IL-6 ve IL-17 has been evaluated semi-quantitatively by 'quickscore' method. We found that the intensity of TNF-α staining was high in the miscarriage group, and this has been found in previous studies. Unlike some previous studies, the intensity of IL-6 staining was higher in the miscarriage groups only in decidual glandular epithelium. The intensity of IL-6 staining was found to be higher in the miscarriage group with chromosome anomaly than in the miscarriage group without chromosome anomaly. There was no significant difference in IL-17 levels between any of the groups. Cytokines are considered to play an important role in the maintenance of pregnancy but the exact mechanism between them and the mutual regulation relationship were not been fully understood, which need our further study.

Does repeat administration of misoprostol for early pregnancy loss increase the treatment success rate? Repeat administration of misoprostol does not increase the treatment success rate, and is associated with more analgesics use. Misoprostol reduces the need for surgical evacuation and shortens the time to complete expulsion in patients with early pregnancy loss. However, the impact of repeat doses of misoprostol is not clear. A randomized clinical trial was conducted in a single tertiary hospital, recruiting women with early pregnancy loss (misoprostol vaginally on Day 1, and were then randomly assigned into two groups: Patients in the single-dose group were evaluated on Day 8. Patients in the repeat-dose group were evaluated on Day 4, when they were given a repeat dose if required, and scheduled for re-evaluation on Day 8. If complete expulsion was not achieved on Day 8 (endometrial thickness >15 mm or the presence of gestational sac on transvaginal sonography), participants underwent surgical evacuation. The primary outcome was treatment success, defined as no need for surgical intervention up to Day 8. Final analysis included 87 participants in the single-dose group and 84 participants in the repeat-dose group, out of whom 41 (48.8%) received a second dose. Treatment succeeded in 67 (77%) patients in the single-dose group and 64 (76%) patients in the repeat-dose group (RR 0.98; 95% CI 0.83-1.16; P = 0.89). Patients in the repeat-dose group reported more use of over the counter analgesics (82.1% versus 69.0%, P = 0.04). The study was not blinded and our definition of complete expulsion may be debated. Follow-up time was not equal in all participants, since some had a complete expulsion on Day 4 and some underwent emergent D&C before Day 8. This, however, should not affect the primary outcome. Our results suggest that a single-dose protocol is superior to a repeat-dose protocol due to a comparable success rate and more favorable outcomes regarding the need for

Full Text Available We present a case of sonographic demonstration of quadruplet heterotopic pregnancy consisting of twin intrauterine (IU pregnancy and a twin adnexal pregnancy after ovulation induction (OI with clomiphene citrate (CC and timed intercourse (TI. Both heterotopic pregnancy and spontaneous twinning are frequent after OI, this combination although extremely rare must be kept in mind. The role of early transvaginal sonography and serum beta human chorionic gonadotrophin after missed periods helps in early diagnosis. It gives us an opportunity for medical management, saving the patient the agony of surgery along with loss of pregnancy. The management of heterotopic pregnancy is controversial. This patient did not have a viable IU pregnancy and both the sacs in the adnexa were small. Thus, we treated her successfully by medical management with systemic methotrexate, with regular follow-up. This patient successfully conceived after 6 months with OI and TI, with ovulation occurring from the same side of the previous ectopic. She had a viable IU gestation corresponding to 12 weeks.
Full Text Available Background: Recurrent pregnancy loss (RPL defined by two or more failed pregnancies before 20 weeks of gestation. Several factors play a role in RPL including thrombophilic conditions which can be influenced by gene polymorphisms. Plasminogen activator inhibitor-1 (PAI-1 and angiotensin converting enzyme (ACE genes are closely related to fibrinolytic process, embryonic development and pregnancy success. Objective: The aim of this study was to investigate the relationship between RPL and common polymorphisms in ACE and PAI-1 genes. Materials and Methods: In this case control study, 100 women with recurrent abortions (at least two were selected as cases and 100 healthy women with two or more normal term deliveries without a history of abortion as controls. Total genomic DNA was isolated from blood leukocytes. The status of the PAI-1 4G/5G and ACE (D/I polymorphism was determined by PCR-RFLP. Results: Homozygosity for PAI-1 4G polymorphism was seen in 17 cases (17%, and 5 controls (5% (p=0.006 so patients with homozygote 4G mutation were significantly more prone to RPL in contrast to control group (OR: 4.63, % 95 CI: 1.55-13.84. In addition, 7 patients (7 %, and no one from the control group, were homozygote (I/I for ACE polymorphism (p=0.034, suggesting no significant associations between ACE D allele or DD genotype and RPL. Conclusion: Considering these results, because 4G/4G polymorphism for PAI-1 gene could be a thrombophilic variant leading to abortion, analysis of this mutation and other susceptibility factors are recommended in patients with RPL.

Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome and is often underdiagnosed. Intramural hematoma is the most frequent angiographic presentation and is a challenging diagnosis that may require intravascular imaging techniques to confirm it and guide treatment. It affects mostly young women without coronary risk factors and is usually associated with fibromuscular dysplasia. SCAD has an underlying disease in 80% of patients. A SMAD3 mutation has been linked to aneurysm-osteoarthritis syndrome and has been identified as a cause of familial thoracic aortic aneurysm and dissection. The first reported case, to our knowledge, of a SMAD3 mutation underlying SCAD is described here. Copyright © 2016 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

Plasminogen activator inhibitor type 1 (PAI-1) regulates fibrinolysis, and the common promoter region variants -675G/A (4G/5G) and -844G/A are associated with increased thrombotic risk. Despite evidence linking altered fibrinolysis with adverse pregnancy events, including idiopathic recurrent pregnancy loss (RPL), the contribution of PAI-1 variants to RPL risk remains controversial. We investigated the association between the PAI-1 -844G/A and 4G/5G (-675G/A) variants with altered risk of RPL. This was a case-control study involving 304 women with confirmed RPL and 371 age- and ethnically matched control women. PAI-1 genotyping was performed by PCR single-specific primer -675 (G/A) and real-time PCR (-844G/A) analysis. Minor allele frequency (MAF) of 4G/5G (P 5G single-nucleotide polymorphism (SNP) was significantly associated with RPL under additive, dominant, and recessive genetic models; no association of -844G/A with RPL was seen irrespective of the genetic model tested. Taking common -844G/5G haplotype as reference (OR = 1.00), multivariate analysis confirmed the association of 4G-containing -844A/4G (P 5G, but not -844G/A, PAI-1 variant is associated with an increased risk of RPL. © 2013 John Wiley & Sons Ltd.

We report of a maternal sternal fracture during a spontaneous delivery in a 31-year-old primipara without a suitable trauma. The putative mechanism of fracture was strong hyperflexion of the thoracic spine and additional cervical flexion with pushing the chin to the thorax due to active management of labour. The history of the healthy woman was free of related risk factors. A possible promoting factor might be pregnancy-induced bone loss. Although there were clear symptoms, the diagnosis of the fracture was delayed by a week because nobody took account of such a possibility.

Recently, mitochondria have been localized to astrocytic processes where they shape Ca2+ signaling; this relationship has not been examined in models of ischemia/reperfusion. We biolistically transfected astrocytes in rat hippocampal slice cultures to facilitate fluorescent confocal microscopy, and subjected these slices to transient oxygen/glucose deprivation (OGD) that causes delayed excitotoxic death of CA1 pyramidal neurons. This insult caused a delayed loss of mitochondria from astrocytic processes and increased colocalization of mitochondria with the autophagosome marker LC3B. The losses of neurons in area CA1 and mitochondria in astrocytic processes were blocked by ionotropic glutamate receptor (iGluR) antagonists, tetrodotoxin, ziconotide (Ca2+ channel blocker), two inhibitors of reversed Na+/Ca2+ exchange (KB-R7943, YM-244769), or two inhibitors of calcineurin (cyclosporin-A, FK506). The effects of OGD were mimicked by NMDA. The glutamate uptake inhibitor (3S)-3-[[3-[[4-(trifluoromethyl)benzoyl]amino]phenyl]methoxy]-l-aspartate increased neuronal loss after OGD or NMDA, and blocked the loss of astrocytic mitochondria. Exogenous glutamate in the presence of iGluR antagonists caused a loss of mitochondria without a decrease in neurons in area CA1. Using the genetic Ca2+ indicator Lck-GCaMP-6S, we observed two types of Ca2+ signals: (1) in the cytoplasm surrounding mitochondria (mitochondrially centered) and (2) traversing the space between mitochondria (extramitochondrial). The spatial spread, kinetics, and frequency of these events were different. The amplitude of both types was doubled and the spread of both types changed by ∼2-fold 24 h after OGD. Together, these data suggest that pathologic activation of glutamate transport and increased astrocytic Ca2+ through reversed Na+/Ca2+ exchange triggers mitochondrial loss and dramatic increases in Ca2+ signaling in astrocytic processes. SIGNIFICANCE STATEMENT Astrocytes, the most abundant cell type in the

to 31 December 2006. Outcome data were retrieved from the National Board of Health. Results: Among 2038 twin pregnancies, 1757 (86.2%) were dichorionic (DC) and 281 (13.8%) were monochorionic diamniotic (MC). In MC pregnancies, the rate of spontaneous fetal loss in both second and third trimesters...... pregnancies with two live fetuses at 24 weeks, the proportion with two live infants at 28 days after delivery was 97.5% and 95.1%, respectively. Conclusions: The increased incidence of fetal loss in MC pregnancies compared with DC pregnancies predominantly occurs before 24 weeks' gestation. After this stage......, although the risk of intrauterine fetal death is still higher in MC than in DC pregnancies, if both fetuses are alive at 24 weeks, the chance of a woman having two live infants 1 month after delivery is similar in MC and DC pregnancies....

Recurrent pregnancy loss (RPL) caused by various genetic and non-genetic factors. After chromosome abnormality, thrombophilia is one of the most important genetic factors that could cause RPL. Factor V Leiden and factor II G20210A mutation were the most common mutations cause thrombophilia in the world. The purpose of this study was to determine the frequency of factor V Leiden and prothrombine gene mutations in women with RPL compared with women who had uneventful pregnancies. This case control study evaluates the frequency of factor V-Leiden and factor II G20210 genotypes in 80 women with two or more pregnancy losses, compared with 80 women without adverse pregnancy outcome. The mutations were assessed by PCR-RFLP. Frequency of the factor V Leiden among cases was 2.5%, which was higher than controls (1.25%), but the difference was not significant. No factor II G20210 mutation was found among cases and controls. These data did not confirm that factor V Leiden and factor II G20210 mutation might play a role in recurrent pregnancy loss in Iranian women.

When administered inappropriately, first-trimester misoprostol management of induced or spontaneous abortion can result in loss or damage of a continuing pregnancy. Despite these serious consequences, such misoprostol exposures continue to occur. Unfortunately, contributing factors and preventive measures receive little attention. We describe the cases of 4 women in whom misoprostol was inappropriately administered during management of induced and presumed spontaneous abortion. In each case, careful adherence to published clinical guidance could have avoided the exposures. © 2017 Wiley Periodicals, Inc.

The loss of gene transfer capacity in retroviral vectors constitutes a major disadvantage in the development of retroviral vectors for gene therapy applications. In the present work the loss of a vector's capacity to perform reverse transcription was studied as a possible explanation for the low stability of retroviral vectors from the production stage to the target cell gene transfer event. Inactivation studies were performed with murine leukemia virus vectors at 37 degrees C and several residual activities were tested, including viral infectivity, reverse transcription capacity, reverse transcriptase (RT) activities and viral RNA stability. The results indicate a high correlation between loss of infectivity and the capacity of the virus to perform the initial steps of reverse transcription. To further understand the thermosensitivity of the reverse transcription process, the two enzyme activities of RT were investigated. The results indicate that, although the inactivation rate of the DNA polymerase is faster than that of RNase H, the decline of these two enzyme activities is significantly slower than that of reverse transcription. Also, viral RNA stability is not implicated in the loss of the virus capacity to perform reverse transcription as the rate of viral RNA degradation was very slow. Furthermore, it was observed that the amount of viral RNA that entered the cells decreased slowly due to viral inactivation at 37 degrees C. The reverse transcription process is thermolabile and this sensitivity determines the rate of retroviral inactivation. Strategies targeting stabilization of the reverse transcription complex should be pursued to improve the applicability of retroviral vectors in gene therapy studies. (c) 2008 John Wiley & Sons, Ltd.

To determine whether chemically induced miscarriage affects fetomaternal trafficking in a mouse model, we measured the amount of fetal DNA present in various maternal organs by polymerase chain reaction amplification following exposure to lipopolysaccharide (LPS). As the frequency of fetal cells and the number of animals with detectable microchimerism following LPS injection were significantly increased, particularly in lung tissue compared to controls, with no signs of an inflammatory response, we conclude that LPS-induced miscarriage results in increased murine fetomaternal cell trafficking, supporting a relationship between fetal loss and the establishment of fetal cell microchimerism.

Full Text Available INTRODUCTION: HISTORY: A 30 year old lady in her 32 weeks gestation period was referred to our ophthalmology clinic with chief complaints of diminution of vision in both eyes for 4 months duration. Her medical history was suggestive of uncontrolled hypertension. On Ophthalmic evaluation she had best corrected visual acuity of 20/200 in both eyes with normal color vision. Her pupils were bilaterally equal in size and normally reacting to light. The intraocular pressure was within normal range and anterior segment evaluation was within normal limits. Dilated fundus evaluation revealed only arterio - venous crossing changes, mottled retina and resolving hard exudates in both eyes [Fig 1a, & 1 b]. The fundus picture could not explain the severity of vision loss in the patient which prompted us for further workup.

To evaluate whether vanishing twin (VT) pregnancies achieved by in vitro fertilization and intracytoplasmic sperm injection (IVF-ICSI) had a more adverse perinatal outcome than those after natural conception. Longitudinal, retrospective cohort study. Tertiary university hospital. Three hundred and six (78 after IVF-ICSI and 228 after natural conception) VT pregnancies over a 22-year period, with VT cases matched to primarily singleton controls. None. Obstetric and neonatal outcome data. The incidence of VT was statistically significantly higher after natural conception (18.2% of twins) than after IVF-ICSI (12.6% of twins). The odds of VT in pregnancies complicated with pregestational or gestational diabetes were disproportionally higher in IVF-ICSI cases than in spontaneously conceived VT pregnancies (adjusted odds ratio [AOR]: 0.80 vs. 3.10 and 1.00 vs. 1.07, respectively). Previous induced abortion (AOR 1.34) or second-trimester fetal loss (AOR 3.3) increased the risk of VT pregnancies after spontaneous conception. Gestational diabetes mellitus in both the previous (AOR 5.41) and the present (AOR 2.3) pregnancy as well as chronic maternal diseases (AOR 3.5) and placentation anomalies all represented independent risk factors for VT after IVF-ICSI. Vanishing twin pregnancies had a lower prevalence and a worse perinatal outcome after IVF-ICSI as compared with those of their spontaneously conceived counterparts.

Full Text Available Aim: To evaluate the role of uterine natural killer (uNK CD56dim and CD16+ cells in patients with refractory antiphospholipid, antibody-mediated, recurrent, pregnancy loss. Settings and Design: A case–control study was conducted between 2012 and 2015 at a university hospital. Patients and Methods: A group of 118 women with a history of antiphospholipid antibody syndrome experiencing fetal loss in spite of low dose aspirin (LDA and low molecular weight heparin (LMWH treatment in the current pregnancy were included in this study. A group of 32 patients undergoing an elective termination of viable pregnancies before 20 weeks were taken as controls. Suction evacuation was performed to collect abortus specimens, and uterine wall curettage was performed to collect decidua specimens, which were then stained using monoclonal antibodies specific to CD56 and CD16. Statistics: Statistical analyses were performed using the Statistical Package for the Social Sciences version 18 software. Chi-square and Fisher exact tests were used for making comparison between the groups. Results: Abnormal fetal karyotype was found in nine (9/97 cases of the study group, which means that abnormal karyotype accounts for only 9.3% of the causes of failure of treatment. Abnormal karyotype was found in four cases of the control group. Only cases with normal karyotyping were subjected to decidual uNK cells analysis. We found that CD56dim and CD16+ were found in the decidua of 79 cases (79/97, which means that aberrant natural killer cells expression might account for 81.4% of the cases of refractory antiphospholipid antibody (APA-mediated recurrent pregnancy loss. Conclusion: CD56dim and CD16+uNK cells might be correlated with refractory APA-mediated recurrent pregnancy loss.

To investigate fetomaternal microchimerism in women with induced abortion or spontaneous pregnancy loss. Peripheral blood samples were obtained from 76 healthy women who underwent dilation and curettage in the first trimester but had never had an abortion or male delivery before. Samples were collected at three time points: just before, 7 days after, and 30 days after abortion. Y chromosome-specific, nested polymerase chain reaction targeting the sex-determining region of Y (SRY) was used to test DNA extracted from buffy coat cells. DNA was also extracted from the chorion to determine sex. The sensitivity of our assay allowed detection of approximately one male cell in 100,000 female cells. Thirty-six male and 40 female chorions were obtained. Male DNA was found in 52.8% of women who had a male chorion before abortion, decreasing to 5.6% at 7 days after abortion. At 30 days after abortion, no male DNA was detected. Male DNA was never detected at any point from women with a female chorion. Fetal cells in the maternal circulation are undetectable 30 days after induced abortion or spontaneous pregnancy loss. Fetal cells may be harbored in maternal organs.

This study compares the frequencies of plasminogen activator inhibitor-1 (-675) 4G/5G polymorphism and its relationship with eight antiphospholipid antibodies (aPLs) in serum of 157 patients with repeated pregnancy loss (RPL). PAI-1 (-675) 4G/5G polymorphism was determined using standard PCR-RFLP method. Enzyme-linked immunosorbent assay was used for the detection of aPLs against ph-serine, ph-ethanolamine, ph-inositol, ph-DL-glycerol, phosphatidic acid, annexin V, cardiolipin, and beta2-GPI. Allelic frequency and distribution of genotypes were calculated. The prevalence of the risk conferring 4G allele and 4G/4G homozygous genotype in patients and controls was compared, and the correlation between aPLs positivity and PAI-1 4G/4G genotype was tested by chi-square test. Statistically highly significant correlation between RPL and PAI-1 (-675) 4G/4G genotype was found. No correlation between PAI-1 (-675) 4G/5G polymorphism and the presence of antiphospholipid antibodies in RPL patients was observed. PAI-1 (-675) 4G/4G homozygous genotype increases the risk of RPL independently from the aPLs positivity. © 2013 John Wiley & Sons Ltd.

Full Text Available Thrombophilia may be anticipated by single or combined hereditary defects in encoding genes factor V, Prothrombin, and MTHFR. The aim of this study was to determine the prevalence and associated risks of V Leiden (G1691A, Prothrombin (G20210A, and MTHFR (C677T mutations in Saudi women with Deep Vein Thrombosis (DVT and women with recurrent pregnancy loss (RPL. Protein C and protein S activity were measured to determine combined effects, if any. We examined 60 women with a history of DVT and 60 with RPL, extracted DNA from EDTA blood and determined three mutations by using multiplex PCR reactions followed by Strip Assay KIT. Pro C Global assay was used to determine the cutoff value [PCATNR = 0.80]. Protein C/S chromogenic assay was used to estimate protein C and S percentages. Frequency of Factor V Leiden G/A genotype in patients with DVT 7 (11.6% had a significant association for DVT χ2 (OR = 5.1, P = 0.03. In women with RPL the three mutations did not show any significant association, levels of Protein C, protein S and PCAT-NR in patient groups not different from controls (P > 0.05. In conclusion, we recommend expanding on these data to provide larger-scale studies.

The association between plasminogen activator inhibitor-1 (PAI-1) 4G/5G polymorphism and recurrent pregnancy loss (RPL) risk is still contradictory. We thus performed a meta-analysis. Relevant studies were searched for in PubMed, Web of Science, Embase, and Cochrane Library. An odds ratio (OR) with a 95% confidence interval (CI) was used to assess the association between PAI-1 4G/5G polymorphism and RPL risk. A total of 22 studies with 4306 cases and 3076 controls were included in this meta-analysis. We found that PAI-1 4G/5G polymorphism was significantly associated with an increased RPL risk (OR=1.89; 95% CI 1.34-2.67; P=0.0003). In the subgroup analysis by race, PAI-1 4G/5G polymorphism was significantly associated with an increased RPL risk in Caucasians (OR=2.23; 95% CI 1.44-3.46; P=0.0003). However, no significant association was observed in Asians (OR=1.47; 95% CI 0.84-2.59; P=0.18). In conclusion, this meta-analysis suggests that PAI-1 4G/5G polymorphism might be associated with RPL development in Caucasians.

Loss to care is high among asymptomatic HIV-infected women initiated on antiretroviral therapy (ART) during pregnancy or in the postpartum period. However, whether pregnancy itself plays a role in the high loss to care rate is uncertain. We compared loss to care over seven years between pregnant and non-pregnant women at enrollment into HIV care in the Democratic Republic of Congo (DRC). We conducted a retrospective analysis of all ART-naive women aged 15-45 initiating HIV care at two large clinics in Kinshasa, DRC, from 2007-2013. Pregnancy status was recorded at care enrollment. Patients were classified as having no follow-up if they did not return to care after the initial enrollment visit. Among those with at least one follow-up visit after enrollment, we classified patients as lost to care if more than 365 days had passed since their last clinic visit. We used logistic regression to model the association between pregnancy status and no follow-up, and Cox proportional hazards regression to model the association between pregnancy status and time to loss to care. Of 2175 women included in the analysis, 1497 (68.8%) were pregnant at enrollment. Compared to non-pregnant women, pregnant women were less likely to be over 35 years of age (19.1% vs. 31.9%, p<0.0001) and less likely to be in WHO stage III or IV (9.0% vs. 26.3%, p<0.0001). Among pregnant women, 106 (7.1%) were not seen after enrollment, versus 25 (3.7%) non-pregnant women (adjusted odds ratio 2.01, 95% CI 1.24-3.24). Of the 2,044 women with at least one follow-up visit, 46.5% of pregnant women and 46.7% of non-pregnant women were lost to care by 5 years; hazards of loss to care were similar for pregnant and non-pregnant women (adjusted hazard ratio 1.08, 95% CI 0.93-1.26). In this large cohort of HIV-infected women, patients pregnant at care enrollment were more likely to never return for follow-up. Among those who attended at least one follow-up visit, loss to care was not different between pregnant and

A repeated or habitual miscarriage (PSP) is defined as three or more consecutive losses of pregnancy. In the first three months of pregnancy, habitual miscarriages occur in about 1% of pregnant women, out of which 50% are of an unknown etiology. It is believed that among them, the greatest number is the consequence of an inadequate alloimmune response of a women to the pregnancy. The endocrine and immune systems are in a close interaction during the implantation and maintaining of pregnancy. This communication is the most obvious on endometrium of pregnancy decidua. The aim of the study was to identify the number and the subpopulation distribution of the decidual NK cells in the decidua by using an immunohistochemical method. The research included a group of 30 women who had had two spontaneous miscarriages consecutively in the first three months of their pregnancy, while the curettage after the third spontaneous abortion was histopathologically and immunohistochemically analyzed. The control group consisted of 20 women without a problematic reproductive anamnesis, who had had their pregnancy terminated for social reasons. The criteria for the eliminating from the research were the diagnosed uterus anomalies, positive screening on thrombophilia, as well as women suffering from diabetes melitus and the ones with the thyroid gland function disorder. The number and the phenotype structure of the uterus NK cells were significantly different between the decidua of a normal pregnancy and that in PSP. In the decidua in PSP, there were much more NK cells with the phenotype of the peripheral circulation CD57 and CD56dim, while in the decidua of the control group the dominant cells were the typical uNK cell subpopulation CD56bright. The above mentioned results show that the disregulation of the immunocompetent cells of the decidua, by creating an inadequate cytokine milieu, is one of the mechanism of rejecting the semiallogeneic blastocyst.

Full Text Available Abstract Background: Recurrent pregnancy loss (RPL is a heterogeneous condition with the prevalence of more than 1% among women of reproductive age, which is defined as the occurrence of more than two miscarriages. Immune-mediators, cytokines, determine the role of immune cells in response to tissue incompatibility conditions. Colony stimulating factor 3 (CSF3 is a cytokine affecting the expression of other cytokines such as IL-4, and suppressing the immune response against semi-allograft embryo. This study was done for the first time on the association of the rs1042658 polymorphism at 3’UTR of the CSF3 gene with the susceptibility to recurrent pregnancy loss, supposing the effect of it on the expression level and stability of the CSF3 gene transcript. Materials and Methods: 122 RPL women and 140 healthy fertile women as a control group were enrolled in this case-control study. Genotype distribution of the selected polymorphism was evaluated by T-ARMS PCR method and the results were analyzed by logistic regression test. Results: comparison of the genotypic frequencies in the 3'UTR of the CSF3 gene in patients and controls resulted in the statistically significant difference in the incidence of pregnancy loss in order to the protection effect of the genotypes carrying T allele was observed between two groups (p<0.05. History of the abortion among the relatives of RPL women versus the relatives of controls showed significant differences (p=0.05. Conclusion: Findings showed significant relationship between rs1042658 polymorphism and the risk of recurrent pregnancy loss, which can affect the susceptibility of the condition.
Full Text Available Background: Recurrent pregnancy loss (RPL is defined as two or more miscarriages before the 20th week of gestation and its etiology is unknown in 50% of the cases. Interleukin 6 is an immune mediator, plays a regulatory role in embryo implantation and placental development. Objective: The purpose was to assess the association between IL-6 -634C/G polymorphism and, susceptibility to idiopathic RPL for the first time in Iran. Materials and Methods: In total 121 women with RPL and 121 healthy women as control group were enrolled in this case-control study. This study was performed from August 2013 to October 2014 in the Molecular Genetics Laboratory of Arsanjan University. Candidate polymorphism was evaluated by PCR-RFLP method on extracted genomic DNA. Data was analyzed using the statistical SPSS package. Results: Our results showed an increased risk of RPL in patients with GG + GC genotype (OR=5.1, 95%CI: 1.04-25.3, p=0.04 in comparison to CC genotype. The frequency of mutant allele G in patients and controls was 0.75 and 0.66 respectively. The mutant allele G predisposes women to miscarriage 1.5 times greater than controls (OR=1.5, 95%CI: 1.03-2.27, p=0.036. The mean number of live births in RPL women (1.3±2.3 was significantly lower compared to control women (4.8±2.3. Conclusion: This study indicated that the promoter polymorphism (-634C/G of the IL-6 gene has likely influence on individual susceptibility to RPL.

Deregulated immunity is one of the most important factors implicated in recurrent pregnancy loss (RPL). The possible role of interleukin-33 (IL-33) and forkhead/winged helix transcription factor (Foxp3) in RPL have not been fully investigated. We aimed to evaluate IL-33 rs1929992 and Foxp3 rs2232365 single nucleotide polymorphisms (SNPs) and their serum levels in Egyptian RPL females. Blood samples were collected from 142 RPL patients and 123 women as healthy controls. IL-33 rs1929992 SNP was determined by polymerase chain reaction restriction fragment length polymorphism and Foxp3 rs2232365 SNP was determined using allele specific polymerase chain reaction. The serum IL-33 and Foxp3 levels were measured by enzyme linked immunosorbent assay. Foxp3 rs2232365 SNP showed statistically significant association with RPL. The risk of RPL was significantly higher in women carrying Foxp3 G allele than those carrying A allele. Lower serum levels of Foxp3 and IL-33 were observed in RPL patients than controls (P < 0.001). Foxp3 serum levels were much lower in carriers of G allele than those carrying A allele in all studied groups. Foxp3 rs2232365 SNP could be considered as a risk factor for RPL. The lowered serum levels of IL-33 and Foxp3 in RPL patients suggested that they might have an important role in the pathogenesis of the disease. Therefore, we hypothesized that Foxp3 polymorphisms may be important in RPL pathogenesis. Copyright © 2018 Elsevier Ltd. All rights reserved.

Objective Recurrent pregnancy loss (RPL) is a heterogeneous disease which is defined as two or more consecutive fetal losses during early pregnancy. Interleukin-1 receptor antagonist (IL-1Ra) is a anti-inflammatory cytokine, which inhibits IL-1 activity by binding to its receptors. The aim of this study was to investigate the association between RPL and IL-1Ra intron 2 polymorphism (86 bp VNTR) in Iranian women. Materials and methods In this case control study, genetic polymorphism was studied in 140 RPL patients and 140 healthy women as controls. Genomic DNA was extracted from the blood samples and polymorphism analysis was performed using the polymerase chain reaction (PCR) method. Finally, the data obtained were analyzed by statistical software. Results We found an increased frequency of the IL-1Ra 1/1 genotype in the case group compared to the control group. Whereas, the frequency of IL-1Ra genotype 1/2 was higher in control group than in the case group. However, we did not observe an association between IL-1Ra 86 bp VNTR polymorphism in intron 2 and RPL patients (p > 0.05). Conclusion IL-1Ra VNTR polymorphism may not be a genetic factor for RPL. However, investigation of IL-1Ra polymorphism was recommended in other populations and patients with recurrent pregnancy loss.

Tuberculosis (TB) was declared a public health emergency by WHO in 2005. The disease is a significant contributor to maternal mortality and is among the three leading causes of death among women aged 15-45 years in high burden areas. The exact incidence of tuberculosis in pregnancy, though not readily available, is expected to be as high as in the general population. Diagnosis of tuberculosis in pregnancy may be challenging, as the symptoms may initially be ascribed to the pregnancy, and the normal weight gain in pregnancy may temporarily mask the associated weight loss. Obstetric complications of TB include spontaneous abortion, small for date uterus, preterm labour, low birth weight, and increased neonatal mortality. Congenital TB though rare, is associated with high perinatal mortality. Rifampicin, INH and Ethambutol are the first line drugs while Pyrazinamide use in pregnancy is gaining popularity. Isoniazid preventive therapy is a WHO innovation aimed at reducing the infection in HIV positive pregnant women. Babies born to this mother should be commenced on INH prophylaxis for six months, after which they are vaccinated with BCG if they test negative. Successful control of TB demands improved living conditions, public enlightenment, primary prevention of HIV/AIDS and BCG vaccination.

Full Text Available Syncope is a common symptom in adolescents who come to the hospital emergency wards. The most common form of syncope is neurogenic type caused by impaired autoregulation of the circulatory system. This syncope is not generally life-threatening condition in a contrast to the less common but most dangerous cardiogenic type (e.g. cardiac arrhythmias due to Wolff–Parkinson–White syndrome, long QT time interval, atrioventricular blocks, haemodynamic obstructions in the outflow tract of the left or right ventricle, cardiomyopathy or coronary abnormalities. This paper refers to a new term, i.e. transient loss of consciousness. According to the new definition of syncope from 2009, temporary loss of consciousness has four components: a sudden occurrence, transient nature, short duration, and spontaneous regression. Currently, there are three main types of syncope associated with the cardiovascular system: neurogenic, orthostatic hypotension and a cardiac. The most common form in adolescents are neurogenic fainting which are often preceded by prodromal symptoms, i.e. decrease in blood pressure and heart rate. They can also occur in response to the stress or unusual situations. In the orthostatic syncope the loss of consciousness occurs in a very short time after the upright position and unlike neurogenic form, usually there are no prodromal symptoms, but tachycardia is present. The rarest, but also the most dangerous form of syncope is a cardiogenic type caused by arrhythmias or structural heart disease. This form may be the first sign of serious heart disease or even precede sudden cardiac death.

Vasculitis is more often a disease of women beyond their reproductive years, leaving the challenges of pregnancy management difficult to study. Pregnancy complications, including pregnancy loss and preterm birth, are higher among women with all forms of vasculitis. It seems that controlling the disease before pregnancy may improve the chances of pregnancy success. Many medications used for vasculitis are considered low risk in pregnancy, including prednisone, colchicine, azathioprine, and tumor necrosis factor inhibitors. Cyclophosphamide, methotrexate, and mycophenolate mofetil should be avoided in pregnancy. Controlling disease with low-risk medications may allow women with vasculitis to have the pregnancies they desire. Copyright © 2017 Elsevier Inc. All rights reserved.

Preston et al. indicated that Protein S (PS) deficiency was associated with stillbirths but not miscarriages. The PS-Tokushima missense variant was reported to serve as a genetic risk factor for deep vein thrombosis in the Japanese population. A previous cross-sectional study showed no increase in the prevalence of PS-Tokushima in patients with recurrent early pregnancy loss or in patients with intra uterine fetal death and/or fetal growth restriction. There has been limited number of prospective studies examining the pregnancy outcome in patients with both a PS deficiency and recurrent pregnancy loss (RPL). We examined the association between PS deficiency, PS-Tokushima and RPL. The study group consisted of 355 Japanese women with two or more consecutive pregnancy losses and 101 parous women. The frequency of PS-Tokushima and the subsequent live birth rate in relation to a PS deficiency defined as low PS-specific activity (total PS activity/total PS antigen) and the carriage of PS-Tokushima were examined. There was no significant difference in the frequency of PS-Tokushima between patients and controls. The 8 patients carriers of PS-Tokushima variant were capable of a subsequent live birth without the use of heparin. There was no significant difference in subsequent live birth rates between patients with low or normal PS-specific activity/PS activity without heparin prophylaxis after excluding miscarriages caused by an abnormal embryonic karyotype using multivariate logistic regression analysis. There was no association between PS-Tokushima and RPL and a PS deficiency or low PS activity was shown not to serve as a reliable clinical predictor of subsequent miscarriage.

At our medical center, female patients who have undergone bariatric surgery are advised to defer pregnancy for 2 years after surgery to avoid the following complications and their potential consequences for the fetus: inadequate gestational weight gain, inadequate postsurgical weight loss, hyperemesis gravidarum, nutritional deficiencies, gestational diabetes, and gestational hypertension. To examine the effect of time from surgery to conception on pregnancy course and outcomes in bariatric patients. University. We identified 73 pregnancies in 54 women who became pregnant after undergoing bariatric surgery. Surgery to conception interval was compared between pregnancies that were carried to delivery and 8 pregnancies that resulted in spontaneous abortion. Of 41 pregnancies that were carried to delivery, 26 occurred in women who had undergone surgery less than 2 years before conception, and 15 occurred in women who had undergone surgery greater than 2 years before conception. Gestational age at delivery, number of neonatal intensive care unit admissions, gestational weight gain, hyperemesis gravidarum, nutritional deficiencies, gestational diabetes, and gestational hypertension during pregnancy were compared for the 2 groups. Eight patients who had spontaneous abortion had a significantly shorter time from surgery to conception. There were no significant differences between our 2 groups in rates of preterm deliveries, neonatal intensive care unit admission, gestational weight gain, hyperemesis, nutritional deficiencies, gestational diabetes, or gestational hypertension. Becoming pregnant within the first 2 years after bariatric surgery appears to have no effect on pregnancy course and outcomes. Women who miscarried had a significantly lower mean surgery to conception interval. These results fail to show an increased rate of pregnancy complications during the first 2 years after bariatric surgery. Copyright © 2017 American Society for Bariatric Surgery. Published by
Full Text Available Introduction and Objectives: Selective neuronal loss (SNL in the reperfused penumbra may impact clinical recovery and is thus important to investigate. Brief proximal middle cerebral artery occlusion (MCAo results in predominantly striatal SNL, yet cortical damage is more relevant given its behavioral implications and that thrombolytic therapy mainly rescues the cortex. Distal temporary MCAo (tMCAo does target the cortex, but the optimal occlusion duration that results in isolated SNL has not been determined. In the present study we assessed different distal tMCAo durations looking for consistently pure SNL.Methods: Microclip distal tMCAo (md-tMCAo was performed in ~6-month old male spontaneously hypertensive rats (SHRs. We previously reported that 45min md-tMCAo in SHRs results in pan-necrosis in the majority of subjects. Accordingly, three shorter MCAo durations were investigated here in decremental succession, namely 30, 22 and 15mins (n=3, 3 and 7 subjects, respectively. Recanalization was confirmed by MR angiography just prior to brain collection at 28 days and T2-weighted MRI was obtained for characterization of ischemic lesions. NeuN, OX42 and GFAP immunohistochemistry appraised changes in neurons, microglia and astrocytes, respectively. Ischemic lesions were categorized into three main types: 1 pan-necrosis; 2 partial infarction; and 3 SNL. Results: Pan-necrosis or partial infarction was present in all 30min and 22min subjects, but not in the 15min group (p < 0.001, in which isolated cortical SNL was consistently present. MRI revealed characteristic hyperintense abnormalities in all rats with pan-necrosis or partial infarction, but no change in any 15min subject. Conclusions: We found that 15min distal MCAo consistently resulted in pure cortical SNL, whereas durations equal or longer than 22min consistently resulted in infarcts. This model may be of use to study the pathophysiology of cortical SNL and its prevention by appropriate

This study contributes to the research literature by providing a new formulation for the cow replacement problem, and it also contributes to the Extension deliverables by providing a user-friendly decision support system tool that would more likely be adopted and applied for practical decision making. The cow value, its related values of a new pregnancy and a pregnancy loss, and their associated replacement policies determine profitability in dairy farming. One objective of this study was to present a simple, interactive, dynamic, and robust formulation of the cow value and the replacement problem, including expectancy of the future production of the cow and the genetic gain of the replacement. The proven hypothesis of this study was that all the above requirements could be achieved by using a Markov chain algorithm. The Markov chain model allowed (1) calculation of a forward expected value of a studied cow and its replacement; (2) use of a single model (the Markov chain) to calculate both the replacement policies and the herd statistics; (3) use of a predefined, preestablished farm reproductive replacement policy; (4) inclusion of a farmer's assessment of the expected future performance of a cow; (5) inclusion of a farmer's assessment of genetic gain with a replacement; and (6) use of a simple spreadsheet or an online system to implement the decision support system. Results clearly demonstrated that the decision policies found with the Markov chain model were consistent with more complex dynamic programming models. The final user-friendly decision support tool is available at http://dairymgt.info/ → Tools → The Economic Value of a Dairy Cow. This tool calculates the cow value instantaneously and is highly interactive, dynamic, and robust. When a Wisconsin dairy farm was studied using the model, the solution policy called for replacing nonpregnant cows 11 mo after calving or months in milk (MIM) if in the first lactation and 9 MIM if in later lactations.

To examine the effect of pregnancy history on the risk of stillbirth. In a population-based cross-sectional study, data were reviewed from all women aged at least 20 years with singleton pregnancies in Finland between 2000 and 2010. The primary outcome-stillbirth-was defined as fetal death after 22 gestational weeks or death of a fetus weighing at least 500 g. Among 604 047 singleton pregnancies, the prevalence of stillbirth was 3.17 per 1000 deliveries. Prevalence was lowest for multiparous women without previous pregnancy loss after adjusting for major pregnancy complications associated with stillbirth (placenta previa, placental abruption, and pre-eclampsia) and other confounders. Relative to these women, stillbirth prevalence was higher among multiparous women with previous spontaneous abortion and/or stillbirth (adjusted odds ratio [aOR] 1.20, 95% confidence interval [CI] 1.05-1.36), nulliparous women with no previous pregnancy loss (aOR 1.23, 95% CI 1.10-1.38), and nulliparous women with prior spontaneous abortion (aOR 1.43, 95% CI 1.18-1.74). Previous pregnancy loss was found to be an independent risk factor for stillbirth, irrespective of the number of prior deliveries. © 2017 International Federation of Gynecology and Obstetrics.

PROBLEM: Women with secondary recurrent pregnancy loss (RPL) after a boy have a reduced chance of live birth in the first pregnancy after referral if they carry HY-restricting HLA class II alleles, but long-term chance of live birth is unknown. METHODS OF STUDY: Live birth was compared for 540...... II alleles decreased chance of live birth: 0 vs 1: hazard ratio 0.75 (95% CI 0.55-1.02); 0 vs 2: HR 0.62 (0.40-0.94). Carriage of HY-restricting HLA class II alleles decreased chance of live birth only if the firstborn was a boy: boy vs girl: HR 0.72 (95% CI 0.55-0.98). CONCLUSION: Maternal carriage...... of HY-restricting HLA class II alleles decreases long-term chance of live birth in women with RPL after a boy....
Full Text Available A case with bilateral spontaneous pneumothorax was presented. Etiology, mechanism, and treatment were discussed on the review of literature. Spontaneous Pneumothorax is a clinical entity resulting from a sudden non traumatic rupture of the lung. Biach reported in 1880 that 78% of 916 patients with spontaneous pneumothorax had tuberculosis. Kjergaard emphasized 1932 the primary importance of subpleural bleb disease. Currently the clinical spectrum of spontaneous pneumothorax seems to have entered a third era with the recognition of the interstitial lung disease and AIDS as a significant etiology. Standard treatment is including: observation, thoracocentesis, tube thoracostomy. Chemical pleurodesis, bullectomy or wedge resection of lung with pleural abrasion and occasionally pleurectomy. Little information has been reported regarding the efficacy of such treatment in spontaneous pneumothorax secondary to non bleb disease

The placenta forms the interface between the maternal and fetal circulation and is critical for the establishment of a healthy pregnancy. Specialized trophoblast cells derived from the embryonic trophectoderm play a pivotal role in the establishment of the placenta. Leukemia inhibitory factor (LIF) is one of the predominant cytokines present in the placenta during early pregnancy. LIF has been shown to regulate trophoblast adhesion and invasion in vitro, however its precise role in vivo is unknown. We hypothesized that LIF would be required for normal placental development in mice. LIF and LIFRα were immunolocalized to placental trophoblasts and fetal vessels in mouse implantation sites during mid-gestation. Temporally blocking LIF action during specific periods of placental development via intraperitoneal administration of our specific LIFRα antagonist, PEGLA, resulted in abnormal placental trophoblast and vascular morphology and reduced activated STAT3 but not ERK. Numerous genes regulating angiogenesis and oxidative stress were altered in the placenta in response to LIF inhibition. Pregnancy viability was also significantly compromised in PEGLA treated mice. Our data suggest that LIF plays an important role in placentation in vivo and the maintenance of healthy pregnancy. PMID:26272398

Existing studies of physical strain and spontaneous abortion are mainly retrospective or based only on pregnancies that have survived the first trimester. Furthermore, almost all studies have relied on averaged measures of physical strain, which tend to blur an effect if peak values during short...... time periods are the relevant measure. We followed a cohort of first pregnancy planners from termination of birth control until pregnancy for a maximum of six menstrual cycles. The analyses include 181 pregnancies, of which 32 were subclinical pregnancies detected by hCG analysis only. During early...... pregnancy the women recorded physical strain prospectively in a structured diary. Physical strain around the time of implantation was associated with later spontaneous abortion. The adjusted risk ratio for women who reported physical strain higher than average at day 6 to 9 after the estimated date...

A register of systemic lupus erythematosus has been open between 1st January 1987 and 31 December 1992 in France. One hundred and seventeen cases of pregnancy from more than 40 centers origin have been prospectively collected. One hundred and three were analyzed. Pregnancy outcome was as following: full term birth (n = 28), premature birth (n = 48), fetal wastage (n = 18 i.e. 13 early spontaneous abortions, two late spontaneous abortions and three stillbirths), therapeutic abortion (n = 5), elective abortion for unwanted pregnancy (n = 4). Four preterm babies died in neo-natal period. Lupus activity was present at pregnancy diagnosis in 28 cases (27%). Of 75 patients with inactive lupus at pregnancy beginning, 27 relapsed during pregnancy and seven in post-partum period. Two patients with nephrotic syndrome died of opportunistic infection. Fetal prognosis is mostly related to proteinuria and absence of anti-SSA antibodies. History of fetal losses, lupus activity at pregnancy beginning, hypertension, use of 20 mg/d or more prednisone dosage during pregnancy influence prematurity. The fetal hypotrophy factors are short duration of pregnancy, lupus activity at beginning of pregnancy, low serum levels of C3 or C4, hypertension, absence of anti-SSA antibodies. Three out of 22 newborns from mother with anti-SSA antibodies developed neonatal lupus: two with cutaneous lupus and one with complete congenital auriculo-ventricular block.
Full Text Available Established causes of recurrent pregnancy loss (RPL include antiphospholipid syndrome, uterine anomalies, parental chromosomal abnormalities, particularly translocations, and abnormal embryonic karyotypes. The number of centers performing preimplantation genetic diagnosis (PGD for patients with translocations has steadily increased worldwide. The live birth rate with PGD was reported to be 27-54%. The live birth rate with natural conception was reported to be 37-63% on the first trial and 65-83% cumulatively. To date, however, there has been no cohort study comparing age and the number of previous miscarriages in matched patients undergoing or not undergoing PGD. Thus, we compared the live birth rate of patients with RPL associated with a translocation undergoing PGD with that of patients who chose natural conception.After genetic counseling, 52 patients who desired natural conception and 37 patients who chose PGD were matched for age and number of previous miscarriages and these comprised the subjects of our study. PGD was performed by means of fluorescence in situ hybridization analysis. The live birth rates on the first PGD trial and the first natural pregnancy after ascertainment of the carrier status were 37.8% and 53.8%, respectively (odds ratio 0.52, 95% confidence interval 0.22-1.23. Cumulative live birth rates were 67.6% and 65.4%, respectively, in the groups undergoing and not undergoing PGD. The time required to become pregnancy was similar in both groups. PGD was found to reduce the miscarriage rate significantly. The prevalence of twin pregnancies was significantly higher in the PGD group. The cost of PGD was $7,956 U.S. per patient.While PGD significantly prevented further miscarriages, there was no difference in the live birth rate. Couples should be fully informed of the similarity in the live birth rate, the similarity in time to become pregnancy, the advantages of PGD, such as the reduction in the miscarriage rate, as well as

There is wide disagreement in the literature on the rate of detection of lupus anticoagulant (LA) in women with recurrent fetal loss (RFL). The aim of this study was to determine the prevalence of LA using four phospholipid-dependant coagulation tests in a large population of Saudi women. We determined the prevalence of LA in women with RFL (n=925), normal pregnancy (n=663), and in healthy blood donors (n=204), at the King Khalid University Hospital, Riyadh. The following coagulation tests were employed: the activated partial thromboplastin time (APTT), platelet neutralization procedure (PNP), kaolin clotting time (KCT) and the dilute Russel's viper venom test (dRVVT). In RFL patients, positive APTT was 10.2%, APTT+PNP 3.6%, KCT 10.5%, and dRVVT 10.9%. In normal pregnancy, the corresponding figures were 12.8%, 3.1%, 10.8%, and 5.6%. Three positive tests occurred in 2.3% of RFL patients, including APTT+KCT 3.5%, APTT+dRVVT 3.9%, and KCT+dRWT 4.1%. The corresponding figures for normal pregnancy were 1.6% for three positive tests, and 3.0%, 1.8%, 2.4%, respectively. The dRVVT was the only test that showed a rate of positive results almost double that seen in normal pregnancy. If only one or even two screening tests were performed, a significant number of LA positive cases would have been missed. This could make a difference to treating physicians as to the possible etiology and management of RFL. It is therefore advisable to routinely use the three tests (APTT, KCT and dRRVT) when screening for LA.

BACKGROUND: Few studies have examined smoking prior to pregnancy and the occurrence of spontaneous abortion, as most studies have addressed the risk of spontaneous abortion in relation to smoking during pregnancy. However, results are not entirely consistent. The aim of the present study...... was to assess the risk of spontaneous abortion considering smoking prior to pregnancy. METHODS: We performed a nested case-control study using prospective data from a population-based cohort comprising 11,088 women aged 20-29 years. From this cohort, women who experienced either a spontaneous abortion (n=343......) or who gave birth (n=1,578) during follow-up were selected. Associations between self-reported smoking at enrollment and subsequent spontaneous abortion were analyzed by means of multiple logistic regression. RESULTS: The risk of spontaneous abortion in relation to pre-pregnancy smoking showed a clear...

Lipopolysaccharide (LPS) injections during pregnancy are well established as models for pregnancy complications, including fetal growth restriction (FGR), thrombophilia, preterm labor and abortion. Indeed, inflammation, as induced by LPS injection has been described as a pivotal factor in cases of miscarriage related to placental tissue damage. The phosphodiesterase-5 inhibitor sildenafil (Viagra®) is currently used to treat FGR cases in women, while low-molecular weight heparin (Fragmin®) is a standard treatment for recurrent miscarriage (RM). However, the pathways and cellular dynamics involved in RM are not completely understood. The aim of this study was to evaluate the protective effect of sildenafil and dalteparin in a mouse model of LPS-induced abortion. Histopathology, ultrastructural analysis and immunofluorescence for P-selectin were studied in two different placental cell types: trophoblast cells and labyrinth endothelial cells. Treatment with sildenafil either alone or in combination with heparin showed the best response against LPS-induced injury during pregnancy. In conclusion, our results support the use of these drugs as future therapeutic agents that may protect the placenta against inflammatory injury in RM events. Analyses of the ultrastructure and placental immunophysiology are important to understand the mechanism underlying RM. These findings may spark future studies and aid in the development of new therapies in cases of RM. © 2016 S. Karger AG, Basel.

A study was conducted to determine whether the incidence of spontaneous abortion was greater than expected near the Three Mile Island (TMI) nuclear power plant during the months following the March 28, 1979 accident. All persons living within five miles of TMI were registered shortly after the accident, and information on pregnancy at the time of the accident was collected. After one year, all pregnancy cases were followed up and outcomes ascertained. Using the life table method, it was found that, given pregnancies after four completed weeks of gestation counting from the first day of the last menstrual period, the estimated incidence of spontaneous abortion (miscarriage before completion of 16 weeks of gestation) was 15.1 per cent for women pregnant at the time of the TMI accident. Combining spontaneous abortions and stillbirths (delivery of a dead fetus after 16 weeks of gestation), the estimated incidence was 16.1 per cent for pregnancies after four completed weeks of gestation. Both incidences are comparable to baseline studies of fetal loss.

To evaluates the pregnancy outcomes in systemic lupus erythematosus (SLE) patients in South Korea and determine the predictive factors for adverse fetal and maternal outcomes. All pregnancies in SLE patients who were seen at the Samsung Medical Center between November 1994 and December 2010 were included and retrospectively analyzed. SLE flares were determined by the Lupus Activity Index-Pregnancy (LAI-P) score. Sixty-two pregnancies were observed in 50 patients. Fifty-one (82.3%) live births and 11 (17.7%) fetal losses were observed. Thirty-eight of the live births (74.5%) were full-term and 13 (25.5%) were preterm births. Fetal losses included three spontaneous abortions, two stillbirths and six therapeutic abortions. Proteinuria during pregnancy was a predictive factor for adverse fetal outcomes (adjusted odds ratio [OR] 12.50; P = 0.032). An LAI-P score was obtained in 36 pregnancies, and SLE flares occurred in 12 pregnancies (33.3%), primarily during the second trimester (46.2%). Renal involvement (69.2%) was the most common SLE flare during pregnancy. All flares were classified as severe flare according to LAI-P scores. SLE flares during pregnancy were strongly affected by proteinuria prior to pregnancy (adjusted OR 30.28; P = 0.024) and the presence of antiphospholipid antibodies (adjusted OR 6.62; P = 0.047). Our study demonstrated a rate of live births and of flares in pregnant lupus patients comparable to recent reports in Western countries.

Full Text Available Miscarriage is the most common complication of pregnancy. Pre-clinical miscarriage has an estimated incidence of 30%, whilst clinical miscarriage has an incidence of 12-15%. Two thirds of pregnancies lost to miscarriage are believed to be attributable to defective placentation, thus a number of studies have sought to identify markers of defective placentation that could be used as clinical biomarkers of miscarriage. Decreased soluble FMS-like tyrosine kinase-1 (sFlt1, placental growth factor (PlGF, and soluble endoglin (sEng in the maternal circulation during the first trimester have recently been proposed as potential markers of pregnancy loss. However, in these studies clinical samples were only obtained once women had presented with symptoms of miscarriage. In this study we prospectively screened serum samples collected from asymptomatic women with a viable fetus. We assessed maternal serum levels of sFlt1, PlGF and sEng across the first trimester of normal pregnancy and compared levels between women who continued to a live birth, to those who subsequently miscarried. Both sFlt1 and PlGF significantly (p≤0.05 increased across gestation in normal pregnancy with serum levels rising from 0.65±0.12 ng/ml at 6 weeks to 1.85±0.24 ng/ml at 12 weeks for sFlt1, and 57.2±19.2 pg/ml to 106±22.7 pg/ml for PlGF. sEng remained unchanged throughout the the first trimester. Importantly we detected a significant (35%, p≤0.05 decrease in sFlt1 levels between our control and miscarriage cohort, however there was significant overlap between cases and controls, suggesting serum sFlt1 is unlikely to be useful as a clinical biomarker in asymptomatic women. Nevertheless, our data suggests a dysregulation of angiogenic factors may be involved in the pathophysiology of miscarriage.

Forty-six reciprocal and six Robertsonian translocation carrier couples who experienced recurrent pregnancy loss underwent fluorescence in situ hybridization-based preimplantation genetic diagnosis (PGD) for the presence of the two translocated chromosomes. Out of 52 couples, 17 (33%) were undergoing infertility treatment. In total, 239 PGD cycles as oocyte retrieval (OR) were applied. The transferrable rate of negatively diagnosed embryos at the cleavage stage was 26.3%; 71 embryos were transferred as single blastocysts. The clinical pregnancy rate per transfer was 60.6%. We obtained 41 healthy live births with 3 incidences of miscarriage (7.0%). The average cumulative live birth rate was 76.9% during 4.6 OR cycles using a mild ovarian stimulation strategy. The outcomes were classified into four groups based on carrier gender and maternal age (young (<38 years) or advanced). PGD was performed for 52 couples of which the average number of OR cycles was 4.1, 2.1, 6.7 and 4.5 in young female and male carriers and female and male carriers of advanced age; the live birth rate for a primiparity was 77.8, 72.7, 66.7 and 50.0% in those groups. These results suggest that the final live birth rate might be influenced by maternal age regardless of the gender of the carrier.

Full Text Available Human kidney predominant protein, NCU-G1, is a highly conserved protein with an unknown biological function. Initially described as a nuclear protein, it was later shown to be a bona fide lysosomal integral membrane protein. To gain insight into the physiological function of NCU-G1, mice with no detectable expression of this gene were created using a gene-trap strategy, and Ncu-g1gt/gt mice were successfully characterized. Lysosomal disorders are mainly caused by lack of or malfunctioning of proteins in the endosomal-lysosomal pathway. The clinical symptoms vary, but often include liver dysfunction. Persistent liver damage activates fibrogenesis and, if unremedied, eventually leads to liver fibrosis/cirrhosis and death. We demonstrate that the disruption of Ncu-g1 results in spontaneous liver fibrosis in mice as the predominant phenotype. Evidence for an increased rate of hepatic cell death, oxidative stress and active fibrogenesis were detected in Ncu-g1gt/gt liver. In addition to collagen deposition, microscopic examination of liver sections revealed accumulation of autofluorescent lipofuscin and iron in Ncu-g1gt/gt Kupffer cells. Because only a few transgenic mouse models have been identified with chronic liver injury and spontaneous liver fibrosis development, we propose that the Ncu-g1gt/gt mouse could be a valuable new tool in the development of novel treatments for the attenuation of fibrosis due to chronic liver damage.

The authors sought to determine whether pregnancies in adolescents following an abortion of pregnancy is associated with an elevated risk for adverse perinatal outcomes. In a cohort study of all adolescent (younger than 18 years) deliveries over a 4-year period at 1 institution, we compared nulliparous women with a history of a prior abortion (cases) to those without a spontaneous loss or abortion of pregnancy (referent) for adverse perinatal outcomes, including preterm birth and fetal growth restriction. Of the 654 included nulliparous adolescent deliveries, 102 (16%) had an abortion before the index pregnancy. Compared with the referent group, adolescents with a history of a abortion were older (17.8 ± 0.8 vs 16.7 ± 1.2 years, P = .0001), enrolled earlier for prenatal care (14.4 ± 5.6 vs 17.2 ± 7.6 weeks, P = .0004), along with a higher incidence of African American race (95% vs 88%, P = .05). The groups did not differ with respect to other maternal demographics. Perinatal outcomes, including spontaneous preterm birth, abnormal placentation, birth weight, and gestational age at delivery, did not differ between the 2 groups. Compared with adolescent women who had just delivered and did not have a prior abortion, women who had just delivered and had a previous abortion were more likely to be older at the age of their first pregnancy and more likely to initiate early prenatal care. Thus, having a prior abortion may improve the health of a pregnancy though adverse outcomes do not differ between the 2 groups.

This analysis compares the rates of spontaneous abortion among women living in the vicinity of a lead smelter with those of women living in a town where blood lead levels were low. Data derive from the obstetric histories of both groups of women obtained while seeking prenatal care for a later pregnancy. A total of 639 women (304 exposed, 335 unexposed) had at least one previous pregnancy and lived at the same address since their first pregnancy. The geometric mean blood lead concentrations in the sample at the time of the interviews were 0.77 mumol/L in the exposed town and 0.25 mumol/L in the unexposed town. The rates of spontaneous abortions in first pregnancies were similar, with 16.4 percent of women in the exposed town and 14.0 percent in the unexposed town reporting loss. The adjusted odds ratio relating town of residence to spontaneous abortion was 1.1 (95% CI = 0.9, 1.4). This analysis represents the first systematic attempt to seek an association between environmental lead exposure and spontaneous abortion. As such, the failure to find a positive association strongly suggests that at the levels of exposure represented in our sample, such an association does not exist.

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

Women who have undergone appendectomy during pregnancy are at higher risk of fetal loss, especially in early pregnancy and with appendiceal perforation, and of premature contractions and labour. Despite the difficulty of diagnosing appendicitis during pregnancy, appendectomy should not be delayed. PMID:15318670

Women who present with pain and bleeding in the first trimester are at risk for ectopic pregnancy, a life-threatening condition. Conditions that predispose a woman to ectopic pregnancy are damaged fallopian tubes from prior tubal surgery or previous pelvic infection, smoking, and conception using assisted reproduction. Many women without risk factors can develop an ectopic pregnancy. A diagnostic algorithm that includes the use of transvaginal ultrasonography, human chorionic gonadotropin (hCG) concentrations, and, sometimes, uterine curettage can definitively diagnose women at risk in a timely manner. The absence of an intrauterine pregnancy above an established cut point of hCG is consistent with an abnormal pregnancy but does not distinguish a miscarriage from an ectopic pregnancy. When the initial hCG value is low, serial hCG values can be used to determine whether a gestation is potentially viable or spontaneously resolving. The minimal rise in hCG for a viable pregnancy is 53% in 2 days. The minimal decline of a spontaneous abortion is 21-35% in 2 days, depending on the initial level. A rise or fall in serial hCG values that is slower than this is suggestive of an ectopic pregnancy. Women diagnosed with an unruptured ectopic pregnancy are potential candidates for medical management with methotrexate. Intramuscular injection with methotrexate can be used to safely treat an ectopic pregnancy with success rates, tubal patency rates, and future fertility that are similar to those obtained with conservative surgery. Success rates using methotrexate are inversely rated to baseline hCG values and are higher using "multidose" compared with "single-dose" regimens. Surgical treatment may be conservative or definitive and should be attempted in most cases via laparoscopy.

Full Text Available Abstract Background Antiphospholipid syndrome (APS has been often associated to RPL since 1980 and some reports in the Literature rarely described antibodies to factor XII in patients with APS. Case history We report the case history of 34-year-old caucasian women with recurrent fetal loss and persistent prolonged activated partial thromboplastin time. Haemostatic tests revealed persistent light decrease of clotting factor XII with normal values of IgG and IgM anticardiolipin antibodies and transient positivity for lupus anticoagulant (LA. Few reports in the Literature described antibodies to factor XII in patient with antiphospholipid syndrome (APS and transient LA. So, once other causes of RPL were excluded, the patient was diagnosed an unusual form of APS associated to antibodies to factor XII, reduced factor XII plasma levels, transient LA and prolonged activated partial thromboplastin time. Discussion We suggest to consider also antibodies directed to clotting factors (e.g. factor XII in our case as second step of thrombophilia screening in RPL, in particular if a persistent prolonged aPTT is present without an apparent cause.

Patients with systemic lupus erythematosus have a poor prognosis of pregnancy, since it is associated with significant maternal and fetal morbidity, including spontaneous miscarriage, pre-eclampsia, intrauterine growth restriction, fetal death and pre-term delivery. We report a case with successful pregnancy in a patient with systemic lupus erythematosus and hypertension. A 39-year-old nulliparous woman presented with systemic lupus erythematosus with antinuclear and antiphospholipid antibodies, hypertension and recurrent pregnancy loss presented for assisted reproduction. The patient responded well to enoxaparin and prednisone during both assisted reproduction and prenatal treatment. This case report indicates that prescription of immunosuppressant and blood thinners can be safely recommended throughout the whole prenatal period in patients with systemic lupus erythematosus. Enoxaparin and prednisone may be prescribed concurrently during pregnancy.

Interventions to prevent excessive gestational weight gain and promote postpartum weight loss have yielded modest results, particularly in overweight and obese women. To examine the impact of a theory-based lifestyle intervention on gestational weight gain, postpartum weight loss, and related maternal and child outcomes and to examine race differences in these outcomes. A randomized controlled trial (target N=400; 200 intervention, 200 standard care; 200 African American, 200 white). Overweight and obese African American and white women ≤16weeks gestation are recruited from obstetrics and gynecology clinics in South Carolina. Intervention participants receive two in-depth counseling sessions (early pregnancy and postpartum), telephone counseling, behavioral podcasts, and social media support that target weight self-monitoring and increasing physical activity and healthy dietary behavior practices, guided by Social Cognitive Theory. Standard care participants receive monthly mailings and a matched number of podcasts on non-weight related topics. All intervention activities last from ≤18weeks gestation to 6months after delivery. Gestational weight gain is the primary outcome. Secondary outcomes are meeting gestational weight gain guidelines (inadequate, adequate, excessive), weekly rate of gestational weight gain, postpartum weight retention, physical activity and dietary behaviors, health-related quality of life, and offspring adiposity. Participants are assessed at baseline (≤16weeks gestation), 32weeks gestation, and 6 and 12months postpartum, and offspring are assessed at 6 and 12months. HIPP is an innovative study that addresses significant gaps in the literature. Primary outcome results are expected in 2019. Copyright © 2018 Elsevier Inc. All rights reserved.

Thrombophilia has been postulated to be a contributor to the pathophysiology of recurrent pregnancy loss (RPL). We investigated the role of the plasminogen activator inhibitor type 1 (PAI-1) 4G/5G and angiotensin converting enzyme (ACE) I/D polymorphisms in Korean patients with RPL. Genotyping was performed using the TaqMan assay in 227 RPL patients and 304 controls. The genotype distributions of both polymorphisms in the RPL group did not differ from those of controls. Because the frequency of being homozygous for ACE D/D and the PAI-I 4G/4G combination has been reported to be significantly higher in RPL patients, this was also analyzed. However, no significant difference was noted; 3.1% of RPL patients had both ACE D/D and PAI-I 4G/4G, as did 4.9% of controls (P = 0.791). The current study suggests that both polymorphisms, either alone or in combination, are not major determinants of the development of RPL in Korean women. © 2014 John Wiley & Sons A/S.

What is the role of the endocannabinoid system (eCS) in the alterations of the endocrine system in a murine model of lipopolysaccharide (LPS)-induced miscarriage? In 7-days pregnant wild type, but not cannabinoid receptor type 1 knockout (CB1-KO) mice, LPS increased COX-2 expression and prostaglandin F 2α (PGF 2α ) production in the uterus leading to lower expression of prolactin receptor in the ovary and a marked regression of corpora lutea (CL), suggesting that the eCS mediates the deleterious effects of LPS on reproductive events. Appropriate systemic progesterone levels are critical for a successful pregnancy outcome. Precocious loss of luteal progesterone (P4) secretion leads to miscarriage in rodents. We have previously shown that LPS administration to pregnant mice induces embryonic resorption accompanied by a dramatic decrease in systemic progesterone levels in a murine model of inflammatory miscarriage, with the eCS mediating these LPS-induced deleterious effects. CD1 wild-type (WT) and CB1-KO mice were randomly allocated to Vehicle (saline; i.p.) or LPS (0.5 μg/g body weight; i.p.) treated groups: (WT-Vehicle; WT-LPS; CB1-KO-Vehicle and CB1-KO-LPS). A single injection was given on day 7 of pregnancy and tissues (blood, ovary, uterus) were collected 6, 12, 24 and 48 h later. P4 and PGF2α plasma levels were determined by radioimmunoassay. Cyclooxygenase-2 (COX-2) mRNA (RT-PCR) and protein (Western blot) content in uterus was assayed. COX-2 and prolactin receptor (PrlR) mRNA levels in the ovary were assayed by RT-PCR. Tissue morphology of the CL was assessed by haematoxylin-eosin staining. Treatment of 7-day pregnant WT mice with LPS induced a P4 withdrawal (p endocannabinoid system in the physiopathology of reproduction as well as the role of this endogenous system as a mediator of LPS deleterious effects on reproductive tissues.

Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy.

Although the first studies were focused only on the association between thrombophilia and RPL, subsequent studies underlined also a potential role of antithrombotic treatment to prevent vascular complication such as venous thromboembolism (VTE during pregnancy. Thromboprophylaxis should be considered also for pregnant subjects carriers of molecular thrombophilia or that previously experienced VTE, in order to prevent VTE during pregnancy, while antithrombotic treatment for VTE should be performed during all pregnant periods.Keywords: thrombophilia, venous thromboembolism, recurrent pregnancy loss, factor V Leiden

Numerous studies have investigated the associations between methylenetetrahydrofolate reductase (MTHFR) gene C677T and A1298C polymorphisms and risk of recurrent pregnancy loss (RPL); however, the results remain controversial. The aim of this study is to drive a more precise estimation of association between MTHFR gene polymorphisms and risk of RPL. We searched PubMed, EMBASE, Cochrane library, Web of Science and China Knowledge Resource Integrated Database for papers on MTHFR gene C677T and A1298C polymorphisms and RPL risk. The pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were used to assess the strength of association in the homozygous model, heterozygous model, dominant model, recessive model and an additive model. The software STATA (Version 13.0) was used for statistical analysis. Overall, 57 articles were included in the final meta-analysis. In maternal group the MTHFR C677T polymorphism showed pooled odds ratios for the homozygous comparison [OR = 2.285, 95 % CI (1.702, 3.067)] and the MTHFR A1298C polymorphism showed pooled odds ratios for recessive model [OR = 1.594, 95 % CI (1.136, 2.238)]. In fetal group the MTHFR C677T polymorphism showed pooled odds ratios for dominant model [OR = 1.037, 95 % CI (0.567, 1.894)] and the MTHFR A1298C polymorphism showed pooled odds ratios for dominant model [OR = 1.495, 95 % CI (1.102, 2.026)]. In summary, the results of our meta-analysis indicate that maternal and paternal MTHFR gene C677T and A1298C polymorphisms are associated with RPL. We also observed a significant association between fetal MTHFR A1298C polymorphism and RPL but not C677T.

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

OBJECTIVE: To clarify the obstetric consequences in a second pregnancy after a first singleton pregnancy complicated by spontaneous preterm delivery or preeclampsia and stratified by the variation in fetal growth. METHODS: In a registry-based cohort study, we identified women having a first...... and second singleton delivery in Denmark from 1978 to 2007 (n=536,419). The exposures and endpoints were preterm delivery, preeclampsia, fetal growth, placental abruption, and stillbirth after 20 weeks of gestation. We used chi and t test to compare differences between incidences on first and second...... pregnancies. RESULTS: Compared with a spontaneous first delivery at term, a delivery between 32 and 36 weeks of gestation increased the risk of preterm delivery in the second pregnancy from 2.7% to 14.7% (odds ratio [OR] 6.12, 95% confidence interval [CI] 5.84-6.42) and the risk of preeclampsia from 1.1% to 1...

The aim of this study was to explore the association of the DNA-methyltransferase (DNMT)-3A and DNMT3B promoter polymorphisms with the risk of human spontaneous abortion after assisted reproduction techniques (ARTs) and natural conception. We collected tissues from women who underwent abortion procedures: (a) chorionic villus samples (CVS) and muscle samples (MS) from spontaneous abortions conceived by ART and natural cycle (study group), n = 152; and (b) CVS and MS from normal early pregnancy and second trimester (control group), n = 155. The single-nucleotide polymorphism (SNP) -448A > G in the DNMT3A promoter region and -149C/T polymorphism of DNMT3B were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and confirmed by sequencing. The allele frequency of -448A among pregnancy loss group and control group was 34.2 % vs. 16.5 %, respectively. Compared with GG carriers, the DNMT3A -448AA homozygotes had an about 16-fold increased risk of spontaneous abortion [odds ratio (OR) = 16.130, 95 % confidence interval (CI), 3.665-70.984], and AG heterozygotes had an OR of 2.027 (95 % CI, 1.247-3.293). However, the distribution of -448A > G in individuals derived from ART pregnancies was not statistically significantly compared with those derived from spontaneous pregnancies (P = 0.661). For DNMT3B, we observed genotype frequencies of 100 % (TT) in the study group and the control group. The DNMT3A -448A > G polymorphism may be a novel functional SNP and contribute to its genetic susceptibility to spontaneous abortion in Chinese women, and ART may not affect the distribution of -448A > G in pregnancy loss and normal pregnancy. The observed TT genotype of DMNT3B suggests that this is the predominant genotype of this population. The findings provide new insights into the etiology of human spontaneous abortion.

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

Full Text Available Background: Spontaneous abortion is the most common adverse pregnancy outcome. We aimed to investigate a possible link between nutrient deficiencies and the risk of spontaneous abortion. Materials and Methods: This case-control study included the case group (n=331 experiencing a spontaneous abortion before 14 weeks of pregnancy and the control group (n=331 who were healthy pregnant women over 14 weeks of pregnancy. The participants filled out Food Frequency Questionnaire (FFQ, in which they reported their frequency of consumption for a given serving of each food item during the past three months, on a daily, weekly or monthly basis. The reported frequency for each food item was converted to a daily intake. Then, consumption of nutrients was compared between the two groups. Results: There are significant differences between the two groups regarding consumed servings/day of vegetables, bread and cereal, meat, poultry, fish, eggs, beans, fats, oils and dairy products (P=0.012, P<0.001, P=0.004, P<0.001, P=0.019, respectively. There are significant differences between the two groups in all micronutrient including folic acid, iron, vitamin C, vitamin B6, vitamin B12 and zinc (P<0.001. Conclusion: Poor nutrientions may be correlated with increased risk of spontaneous abortion
Full Text Available Background: Pregnancy in patients with SLE is associated with a high risk of maternal disease exacerbation in active disease state and adverse fetal outcome. Objective: To analyse maternal and fetal outcome in pregnant lupus patients as well as to identify influence of disease activity on it. Methods: This retrospective observational cross sectional study was done on 27 pregnant lupus patients in feto-maternal medicine wing of the department of Obstetrics and Gynaecology, BSMMU from April 2007 to March 2011. For statistical analysis ‘z’ test of proportion and student’s ‘t’ test was used. Results: Mean age of the patients was 26.6 years. At booking, 8 (29.63% had active lupus while 19 (70.37% was in remission. As complications of SLE, lupus flare was found in 11.1%, lupus nephritis in 25.9% and skin rash in 7.4%. Regarding obstetric complications, PIH was developed in 3.7% and preeclampsia in 11.1% of the patients. Average gestational age at delivery was 34.8 weeks. Birth weight was <2.5kg in 45.8% of neonates. There was IUGR in 33.3% of the cases and 25% of the neonates needed admission in neonatal ICU. There was no neonatal death and none of the 24 neonates had neonatal lupus. In this study there was no maternal mortality. Patients who were in active disease state, most (55.5% delivered preterm, spontaneous abortion occurred in two and IUD in one of the patients. Average birth weight was lower (1.9+.47kg in patients with active SLE than those of with remission (2.3+.68kg. Lupus flare developed in 66.6% with active disease, while in 33.3% with remission. Conclusion: Pregnancy is relatively safe with SLE in remission but considered as high risk in terms of fetal loss and spontaneous abortion.

Full Text Available 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.

Pregnant women who travel to malarious areas and their clinicians need data on the safety of malaria chemoprophylaxis. The effect of exposure to mefloquine on pregnancy and offspring outcomes was evaluated using the F. Hoffmann-La Roche global drug safety database for the time frame 31 January 1986 through 26 October 2010. We investigated pregnancy and fetal outcomes in maternal, paternal, and both-parent exposure cases with a focus on congenital malformations and fetal loss. The main outcome measures were birth defect prevalence and types of malformations. A total of 2506 cases of mefloquine exposure during pregnancy or in the pre- and periconception period were evaluated. Most cases were maternal prospective (outcome of the pregnancy unknown at the time of reporting; n = 2246 [89.6%]) followed by maternal retrospective cases (outcome of the pregnancy known at the time of reporting; n = 227 [9.0%]), with small numbers of paternal and both-parent exposure cases. Of the total 2246 mefloquine maternal prospective exposures (95.2%), 2139 occurred before conception and/or during the first trimester. Of 1383 maternal prospective cases with known outcome, 978 (70.7%) resulted in delivery, 405 (29.3%) resulted in abortion (112 spontaneous, 293 therapeutic), and 43 resulted in birth defects, corresponding to a birth defect prevalence of 4.39% (43 of 978). Prospective cases overall showed no specific pattern of birth malformations. The drug safety database analysis of mefloquine exposure in pregnancy showed that the birth defect prevalence and fetal loss in maternal, prospectively monitored cases were comparable to background rates.

Background: Coffee consumption in Denmark is high also among pregnant women and it is presumably their main source of caffeine intake. Coffee or caffeine intake during pregnancy has been linked to adverse pregnancy outcomes such as spontaneous abortion, stillbirth and reduced fetal growth. However...... a review of the literature indicates that further studies are needed to test the hypothesis of an effect of coffee or caffeine on the risk of adverse pregnancy outcomes.The aim of the thesis was to study the relation between coffee and the risk of fetal death and the relation between caffeine intake...... the effect of caffeine on mean birth weight and gestational age in a randomised controlled double-blinded trial with 1,207 women randomised to either caffeinated or decaffeinated instant coffee. We found no difference in mean birth weight or gestational age between children of mothers randomised...

Full Text Available The lecture considers the influence of obesity in women of reproductive age on somatic and reproductive problems that results in the decline of fertility. Women with obesity in comparison to the women with normal body weight have an increase in both frequency of spontaneous pregnancies and efficiency of treatment for sterility using different methods (stimulation of ovulation and other. After the occurrence of pregnancy in women with obesity, there is an increase in the risks of congenital abnormalities, macrosomia, stillbirth, gestational hypertension, gestational diabetes, premature birth and a number of other complications. Weight loss has a positive effect on menstrual function, increases the probability of conception and birth of a healthy child, reduces the risk of adverse pregnancy outcomes.

Background: Endocrine-related adverse health effects from exposure to heavy metals such as lead, arsenic, cadmium, and mercury are yet to be adequately described. The purpose of this review was to gain insight into maternal exposure to heavy metals, and to identify potential endocrine-related adverse health effects in the mother and the infant. Methods: Relevant databases were searched for original research reports and a total of 46 articles were retained for scrutiny. Required data was extracted from these studies and their methodology was assessed. Results: Impaired fetal growth was observed from exposure to all endocrine disrupting metals, while exposure to lead and arsenic were associated with spontaneous abortion, stillbirth and neonatal deaths. Maternal exposure to arsenic was associated with impaired glucose tolerance in these mothers. Conclusion: Impaired fetal growth, fetal loss, and neonatal deaths were significantly associated with heavy metals exposure during pregnancy; however, hypertension and gestational diabetes require further investigation. - Highlights: • Low and high dose exposure to lead was associated with low birth weight, preterm birth, stillbirths, spontaneous abortions and hypertension. • Exposure to arsenic was associated with fetal loss, stillbirths and spontaneous abortions. • Exposure to cadmium was associated with low birth weight. • Exposure to mercury was associated with spontaneous abortions and neurotoxic effects. • Exposure to copper was associated with low birth weight and spontaneous abortions and exposure to zinc was associated with low birth weight.

Vaginal bleeding in the first trimester has wide differential diagnoses, the most common being a normal early intrauterine pregnancy, with other potential causes including spontaneous abortion and ectopic pregnancy. The incidence of ectopic pregnancy is approximately 2% of all reported pregnancies and is one of the leading causes of maternal mortality worldwide. Clinical signs and symptoms of ectopic pregnancy are often nonspecific. History of pelvic pain with bleeding and positive β-human chorionic gonadotropin should raise the possibility of ectopic pregnancy. Knowledge of the different locations of ectopic pregnancy is of utmost importance, in which ultrasound imaging plays a crucial role. This pictorial essay depicts sonographic findings and essential pitfalls in diagnosing ectopic pregnancy. PMID:28299234

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

Turner's syndrome is characterized by an ovarian failure which occurs in most cases before puberty and leads to infertility. In less than 10% of women with Turner syndrome, puberty may occur and spontaneous pregnancies is possible but with a high risk of fetal loss, chromosomal and congenital abnormalities. We present the case of a 33-year-old woman with a mosaic Turner's syndrome karyotype 45,X/47,XXX who conceived spontaneously and had two successful pregnancies. Short stature was the only manifestation of Turner's syndrome. In the present report, we reviewed the available literature on the fertility of women with Turner's syndrome and the phenotypic effects of mosaicism for a 47,XXX cell line in Turner's syndrome.

Spontaneous pneumothorax is infrequently caused by strenuous exertion. To our knowledge there has only been one case of spontaneous pneumothorax associated with weightlifting reported in the medical literature. We describe three consecutive cases of spontaneous pneumothorax associated with weightlifting. We postulate that spontaneous pneumothorax in these patients may be secondary to improper breathing techniques. It is important that physicians and weight trainers be aware of the association between weight lifting and spontaneous pneumothorax and assure that proper instruction is given to athletes who work with weights.

To investigate whether manual removal of the placenta is associated with significantly more blood loss compared to spontaneous separation of the placenta during cesarean section. This was a randomised study of 200 women with normal pregnancies undergoing cesarean section. Patients were randomly assigned to the study group, manual removal (n=100) or the control group, spontaneous separation (n=100). Operative blood loss was measured using a volume and gravimetric method. Patients postoperative complications were recorded and hemoglobin levels measured at 24 and 48 h. The amount of blood loss associated with spontaneous and manual removal of the placenta was 626+/-253 ml and 589+/-272 ml, respectively. This difference was not significant. There was a decrease in the postoperative hemoglobin levels in both groups which was not significantly different. The incidence of endometritis, wound infection, and the need for blood transfusion was similar in the two groups. Manual delivery of the placenta is not associated with a significantly greater risk of operative blood loss, decreased postoperative hemoglobin levels or increased incidence of endometritis compared with spontaneous placental separation.

developing a depressive episode after spontaneous abortion was significantly higher than in females with a viable pregnancy (RR = 2.19, 95 % CI, 1.05 to 4.56). After adjustment for age and period of amenorrhoea, the difference was not significant. Prevalence of complicated grief was 54.74 % (95 % CI, 46.3-63.18). The relative risk of developing a depressive episode after spontaneous abortion was not significantly higher compared to pregnant women after taking into account age and period of amenorrhoea (POA). Almost half the women developed complicated grief after spontaneous abortion. Of these, a significant proportion also had features of depressive disorder.

A randomized prospective study of 400 women with normal pregnancies undergoing cesarean delivery at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Patients were randomly assigned to the study group, (manual placental removal, n=200) or the control group (spontaneous placental separation, n=200). Operative blood loss was assessed by the volumetric and gravimetric methods. Hemoglobin levels were evaluated the third postoperative day and patient's postoperative complications were recorded. The mean+/-S.D. amount of blood loss associated with manual and spontaneous removal of the placenta was 713+/-240 and 669+/-253 ml, respectively. This difference was statistically significant (P=0.04). There was a postoperative decrease in hemoglobin levels in both groups. Preoperative hemoglobin levels were 11.6+/-3 g/dl in the study group and 11.2+/-1.1 g/dl in the control group, and the difference was statistically significant (P=0.006). The postoperative hemoglobin levels at day 3 were 9.0+/-1.2 g/dl in the study group and 9.9+/-1.2 g/dl in the control group (P=0.003), also a statistically significant difference. The incidence of endometritis, wound infection, and need for blood transfusion was similar in the two groups. Manual delivery of the placenta was significantly associated with greater operative blood loss and greater decrease in postoperative hemoglobin levels, but with shorter operative time compared with spontaneous placental separation. No difference in postoperative complications was noted between the groups.

Objective The Centers for Disease Control and Prevention last estimated a national ectopic pregnancy rate in 1992, when it was 1.97 percent of all reported pregnancies. Since then rates have been reported among privately insured women and regional healthcare provider populations, ranging from 1.6 to 2.45 percent. This study assessed the rate of ectopic pregnancy among Medicaid beneficiaries (New York, California, and Illinois, 2000–03), a previously unstudied population. Study Design We identified Medicaid administrative claims records for inpatient and outpatient encounters with a principal ICD9 diagnosis code for ectopic pregnancy. We calculated the ectopic pregnancy rate among female beneficiaries ages 15–44 as the number of ectopic pregnancies divided by the number of total pregnancies, which included spontaneous abortions, induced abortions, ectopic pregnancies, and all births. We used Poisson regression to assess the risk of ectopic pregnancy by age and race. Results Four-year Medicaid ectopic pregnancy rates were 2.38 percent of pregnancies in New York, 2.07 percent in California, and 2.43 percent in Illinois. Risk was higher among Black women compared to whites in all states (RR= 1.26, 95% CI 1.25 – 1.28, pectopic pregnancy than reported for privately insured women nationwide in the same years. Relying on private insurance databases may underestimate ectopic pregnancy’s burden in the United States population. Furthermore, within this low-income population racial disparities exist.

Approximately 10%-15% of clinically recognized pregnancies end with a first trimester loss. Cytogenetic analysis of products of conception (POC) has revealed that a large proportion of these spontaneous miscarriages are a result of chromosomal abnormalities. However, relatively few studies have evaluated chromosomal abnormalities in pregnancies achieved using assisted reproductive technologies (ART). Here, we review the incidence and type of chromosomal abnormalities that occurred in our infertility patient population undergoing ART and provide a review of the literature pertaining to this subject. A retrospective chart review of all patients from our medical center who conceived using ART between January 2000 and January 2008, who experienced a subsequent early pregnancy loss, and whose POCs were successfully karyotyped were included. We also conducted a literature review in PubMed, searching for other articles on this subject. Two hundred fourteen patients conceived with ART, experienced an early loss, and subsequently underwent a dilation and curettage (D&C) between 2000 and 2008. A total of 59 (27%) patients chose to have cytogenetic testing, and their POCs were successfully karyotyped. The overall rate of aneuploidy in this group was 83%. Our PubMed search revealed a total of 12 studies that were identified and evaluated and deemed appropriate for review. Consistent with most of the literature, we found a high rate of aneuploidy present in infertile patients conceiving using ART. Because an abnormal karyotype provides an explanation for an early loss, this and other studies seem to suggest that routinely carrying out this assessment in such patients may be of value.
INTRODUCTION: Spontaneous\\/primary intracranial hypotension is characterised by orthostatic headache and is associated with characteristic magnetic resonance imaging findings. CASE REPORT: We present a case report of a patient with typical symptoms and classical radiological images. DISCUSSION: Spontaneous intracranial hypotension is an under-recognised cause of headache and can be diagnosed by history of typical orthostatic headache and findings on MRI brain.

OBJECTIVE: To clarify the obstetric consequences in a second pregnancy after a first singleton pregnancy complicated by spontaneous preterm delivery or preeclampsia and stratified by the variation in fetal growth. METHODS: In a registry-based cohort study, we identified women having a first...... pregnancies. RESULTS: Compared with a spontaneous first delivery at term, a delivery between 32 and 36 weeks of gestation increased the risk of preterm delivery in the second pregnancy from 2.7% to 14.7% (odds ratio [OR] 6.12, 95% confidence interval [CI] 5.84-6.42) and the risk of preeclampsia from 1.1% to 1.......8% (OR 1.60, 95% CI 1.41-1.81); a delivery before 28 weeks increased the risk of a second preterm delivery to 26.0% (OR 13.1, 95% CI 10.8-15.9) and a second pregnancy with preeclampsia to 3.2% (OR 2.96, 95% CI 1.80-4.88). A first delivery in preeclamptic women between 32 and 36 weeks, compared...
Full Text Available Lipopolysaccharide (LPS administration to mice on day 7 of gestation led to 100% embryonic resorption after 24 h. In this model, nitric oxide is fundamental for the resorption process. Progesterone may be responsible, at least in part, for a Th2 switch in the feto-maternal interface, inducing active immune tolerance against fetal antigens. Th2 cells promote the development of T cells, producing leukemia inhibitory factor (LIF, which seems to be important due to its immunomodulatory action during early pregnancy. Our aim was to evaluate the involvement of progesterone in the mechanism of LPS-induced embryonic resorption, and whether LIF can mediate hormonal action. Using in vivo and in vitro models, we provide evidence that circulating progesterone is an important component of the process by which infection causes embryonic resorption in mice. Also, LIF seems to be a mediator of the progesterone effect under inflammatory conditions. We found that serum progesterone fell to very low levels after 24 h of LPS exposure. Moreover, progesterone supplementation prevented embryonic resorption and LPS-induced increase of uterine nitric oxide levels in vivo. Results show that LPS diminished the expression of the nuclear progesterone receptor in the uterus after 6 and 12 h of treatment. We investigated the expression of LIF in uterine tissue from pregnant mice and found that progesterone up-regulates LIF mRNA expression in vitro. We observed that LIF was able to modulate the levels of nitric oxide induced by LPS in vitro, suggesting that it could be a potential mediator of the inflammatory action of progesterone. Our observations support the view that progesterone plays a critical role in a successful pregnancy as an anti-inflammatory agent, and that it could have possible therapeutic applications in the prevention of early reproductive failure associated with inflammatory disorders.

Cholecystectomy during pregnancy happens to be the second most common cause of laparotomy. The reported incidence of the procedure is I of every 1250 to 12,500 pregnancies. We have done a retrospective study from january 1989 to december 1994, at Instituto Nacional de Perinatología, having 35,080 deliveries registered, four of them with reported cholecystectomy during pregnancy. The average of maternal age resulted in 20.2 years, varying from 16 to 23 years. Three patients were multigravidas, and just one primigravida. Gestational age at the time of diagnosis and surgery was reported in 17 to 23.4 weeks. We found one twin pregnancy, and that two patients had history of chronic colecistitis. In the 100% of cases laparotomy and cholecystectomy was done, with preterm labor as the most frequent complication. There were 3 fetal loss in study and only 2 pregnancies were delivered at term. In this review the estimated frequency of cholecystectomy was 1 of 8780 deliveries, being the second cause of quirurgical treatment during pregnancy, after appendicectomy. There were reported 50% fetal deaths, and no severe maternal complications.

Pregnancy outcome has been studied in terms of legal abortions, early spontaneous abortions and total number of pregnancies (in an ad hoc study covering 6 counties) as well as various perinatal health problems (on the basis of routinely recorded data for epidemiological surveillance from the Medical Birth Registry of Norway). Apparently, no effects were observed in terms of an increased occurrence of legal abortions, while spontaneous abortions increased from 2.4% of all pregnancies during the last 12 months before the accident to 3% after the accident. At the same time, the total number of pregnancies somewhat decreased. Based on monthly measurements in each municipality of external and internal (food-based) doses, dose-response associations were assessed for a number of perinatal health problems. No associations were observed

Full Text Available The impact of obesity on the outcome of assisted reproduction treatments is debatable. Several studies show that obese women have worse outcomes after undergoing fertility treatment. The researches show a worse response to ovulation induction. In the ovarian stimulation stage these women produce fewer follicles. Fertilization rates are poorer and the embryo quality is lower in young women suffering from obesity. According to some studies, pregnancy rates are lower in obese women and there is an increased risk of early pregnancy loss. Weight loss increases the chance of spontaneous ovulation and conception in women that suffer from overweight and obesity.The aim of this study is to describe the different influencing factors related to body mass index in pregnancy rate achieved by artificial insemination in our population.The results of this study show significant results in patients with higher body mass index was positively associated with duration of infertility, lower levels of luteinizing hormone and intrauterine artificial insemination indication increased .It appears more frequently, but without significant result, anovulation and unexplained cause of infertility among obese women, longer cycles, fewer antral follicles and get fewer mature follicles. The average of pregnancy rates was 12.6% but it did not differ significantly among the body mass index categories.
BACKGROUND: Spontaneous pre-labour rupture of membranes (SPROM) at term is one of the most common complications of pregnancy. It is an important cause of perinatal morbidity and mortality, particularly because it is associated with a latency period from membrane rupture to delivery. OBJECTIVE: To compare the ...

Early reports described adverse perinatal outcomes of pregnancies after weight loss surgery (WLS), which subsequently raised concerns regarding safety. Our objective was to investigate, in a community-based, academic, tertiary care center, the safety of pregnancies after laparoscopic Roux-en-Y gastric bypass (LRYGB) and its potential effect on obesity-related perinatal complications. The pregnancy outcomes of patients delivering infants after LRYGB at our institution were compared with those of control subjects (stratified by body mass index) who had not undergone WLS. The charts were retrospectively reviewed for demographics, delivery route, and perinatal complications. A total of 26 patients who delivered after LRYGB and 254 controls were identified. The mean interval from LRYGB to conception was 25.4 +/- 13.0 months. In general, the perinatal complications in the LRYGB patients were similar to those in the nonobese controls and lower than in the obese and severe obese controls, although statistical significance was not noted for all complications. No spontaneous abortions or stillbirths occurred in the LRYGB patients. No LRYGB patients required intravenous nutrition or hydration. The overall incidence of cesarean section in the LRYGB patients was similar to that in the obese and severely obese controls but significantly greater than that in the nonobese controls. The complication rates were similar in pregnancies occurring "early" (18 mo) after LRYGB. The results of our study have shown that pregnancy after LRYGB is safe, with an incidence of perinatal complications similar to that of nonobese patients, and lower than that of obese and severely obese patients, who had not undergone WLS. Larger studies are required to demonstrate statistically significant improvements in outcome in patients treated with WLS.
Full Text Available "nChorionic villus sampling (CVS is a new method and its true risk of fetal loss and complications is not still clearly determined. The objective of this study was to review the clinical pregnancy outcome of transabdominal CVS (TA-CVS performed on women with minor beta thalassemia. TA-CVS performed on 300 women with a singleton pregnancy and we could follow 213 women until delivery. Data regarding induced legal abortion, spontaneous abortion, vaginal leakage, Vaginal bleeding and deformity of extremities ( limb reduction were obtained by questionnaire in five years. All CVS were performed by one operator. The mean gestation at time of CVS was 82.4±11.3 days. 79.2% of the procedures were made between 10-13 completed weeks and in other women (20.7% TA-CVS was performed at 13-16 weeks. The majority (86.9% required only one puncture. There were 47 pregnancy terminations because of fetal major beta thalassemia diagnosis (18 %. The rate of spontaneous abortion in our study was over ally (1.4% and in two patients vaginal bleeding was noticed. We didn't find any vaginal leakage and limb reduction in our survey. TA-CVS is an accurate and safe procedure in experienced hands. It should be considered as one of the safe available procedures for women who require prenatal genetic diagnosis and wish to receive earlier diagnostic information for probable termination of pregnancy.

Uterine fibroids are a very common finding in women of reproductive age. The majority of fibroids do not change their size during pregnancy, but one-third may grow in the first trimester. Although the data are conflicting and most women with fibroids have uneventful pregnancies, the weight of evidence in the literature suggests that uterine fibroids are associated with an increased rate of spontaneous miscarriage, preterm labor, placenta abruption, malpresentation, labor dystocia, cesarean delivery, and postpartum hemorrhage.

Full Text Available In a historical cohort study we evaluated the effects of spontaneous abortion on subsequent pregnancy outcome. 1693 pregnant women were classifield in three groups: 1100: without any prior pregnancy, group 1; 550: with history of one spontaneous abortion (G2A1, group 2; 43: with two or more prior spontaneous abortions and no other prior pregnancies, group 3. We collected data through interview, patient's records and physical examination. We matched the patients according to their age subgroups, history of chronic disease, drug administration and radiation during current pregnancy and familial marriage. Then we compared adverse outcome of present pregnancy in group 1 and 2 with the women without prior pregnancy. We analysed the data with Chi-square and Fisher's exact methods. In this study we concluded that history of one spontaneous abortion had no effect on subsequent pregnancy except on prolonged ROM (P<0.000, but history of two or more abortions significantly affects occurrence of stillbirth (RR=29, P=0.003 and placenta previa (RR=8.5, P=0.03. These findings suggest that pregnant women with history of two or more spontaneous abortion need special prenatal care.

Objective: To investigate the clinical characteristics and adverse pregnancy outcomes in pregnant women with new onset systemic lupus erythematosus (SLE) during pregnancy. Methods: The clinical data of 263 pregnancies with SLE in the First Affiliated Hospital of Zhongshan University from 2001 to 2015 were collected and analyzed retrospectively. Results: Of all the 263 pregnancies, 188 were diagnosed before pregnancy and 75 were newly diagnosed during pregnancy. Among the 75 new onset SLE, 27, 31, 14 and 3 cases were diagnosed during first trimester, second trimester, third trimester and puerperium, respectively. Active lupus was noted in 81.3% of the patients with new onset SLE. The main clinical manifestations of new onset SLE were lupus nephritis (57.3%) and thrombocytopenia (38.7%). SLEPDAI scores as well as the prevalence of lupus nephritis, and thrombocytopenia in patients with new onset SLE was higher than those in the previously diagnosed ones ( P pregnancies, adverse pregnancy outcomesoccurred in 53 patients, including 34 with pregnancy loss, 15with premature, 8with intrauterine growth restriction, 5with fetal distress and5 with neonatal lupus. Compared with patients withnon-newonset SLE, patients with newonset SLEhad a higher prevalence of adverse pregnancy outcomes (56.4% vs 70.7%, P pregnancy loss (21.8% vs 45.3%, P lupus nephritis and thrombocytopenia. Patients with new onset SLE were more prone to active lupus, lupus nephritis and thrombocytopenia, as well as more adverse pregnancy outcomes and pregnancy loss.
This discussion of ectopic pregnancy covers mortality, definition, etiology, diagnosis and management, and contraception. In the 1979-81 "Report on Confidential Enquiries into Maternal Deaths in England and Wales," ectopic pregnancy accounted for 11.4% of all maternal deaths. Avoidable factors were found in 64% of deaths from ectopic pregnancy, the most common being delay in diagnosis and operative intervention. Ectopic pregnancy is the implantation of the conceptus outside the uterus or in an abnormal location within the uterus. Tubal gestation invariably has a multifactorial etiology and occurs owing to delay in the transport of the fertilized ovum. Table 1 lists causes. Salpingitis is the main cause of tubal pregnancy and now is considered to be due primarily to chlamydia. The consequences of tubal surgery, for whatever reason, and hormonal treatment also are major etiological factors. Every woman of reproductive age, especially if she has 1 or more etiological factors in her past history, who presents with a history of a missed period and irregular vaginal bleeding or abdominal pain, must be considered to have an ectopic pregnancy until proved otherwise. Diagnosis still is essentially a clinical one. In difficult cases use should be made of radioimmunoassay of beta hCG, ultrasonic scanning, and laparoscopy. In 25% of cases, a correct diagnosis was made only at laparotomy. Culdocentesis and endometrial biopsy are of limited use. In cases of ruptured ectopic pregnancy with circulatory collapse, immediate operative intervention is essential. In regard to contraception, the combined oral contraceptive (OC), in suppressing ovulation and thickening the cervical mucus, has a protective effect. Method failure does not increase the incidence of extrauterline pregnancy above normal. The progestagen-only pill is associated with a small increase in the risk of an initial and recurrent ectopic pregnancy. It does not suppress ovulation and may affect tubal motility, but it
Full Text Available Background:Correction of the uremic state by a functioning allograft often restores fertility in women of reproductive age. The rate of fertility significantly differs between industrial countries, developing and middle east countries.On the other hand the results of pregnancy in Kidney Transplantation (KTP patients are significantly better than hemodialysis patients,and pregnancy most often has no side effects on the function of the transplanted kidney.Objectives: The purpose of this study is to investigate the rate of fertility and results of pregnancy among KTP women, and the assessment of the function of transplanted kidneys during pregnancy among those who have received kidneys in Golestan Hospital from 1996 to 2003. Methods: All the transplanted women in child bearing age who were interested in accepting pregnancy were involved in this study. After pregnancy, all the patients were visited twice a month until the 32nd week of pregnancy and their histories were taken and regular clinical examination and necessary paraclinical assessments were carried out. After the 32nd week, they were visited weekly and other necessary assessments were done in addition to previous measures. Taking immunosuppressive drugs was continued with a minor dose reduction and consumption of harmful drugs like some antihypertensives was prohibited. Results: 16 out of 48 women who were at child bearing age and were interested in pregnancy got pregnant and totally 22 cases of pregnancy occurred. Four cases resulted in spontaneous or therapeutic abortion and 3 out of 18 remaining cases had intrauterine fetal death and the others had successful pregnancy. The most common complication was LBW and following that premature labor. Maternal complications were no more than the general population and the function of the transplanted kidney had no decline in most of the cases. Conclusion:Based on what was mentioned,it is concluded that successful KTP can increase the chance of
