ObjectiveTo investigate the association between maternal pregestational blood glucose level and adverse pregnancy outcomes.DesignRetrospective cohort study.SettingThis study was conducted in the Chongqing Municipality of China between April 2010 and December 2016.ParticipantsA total of 60 222 women (60 360 pregnancies) from all 39 counties of Chongqing who participated in the National Free Preconception Health Examination Project and had pregnancy outcomes were included.Primary outcome measuresAdverse pregnancy outcomes included spontaneous abortion, induced abortion or labour due to medical reasons, stillbirth, preterm birth (PTB), macrosomia, large for gestational age, low birth weight (LBW) and small for gestational age.ResultsOf the 60 360 pregnancies, rates of hypoglycaemic, normoglycaemia, impaired fasting glycaemia (IFG) and diabetic hyperglycaemic before conception were 5.06%, 89.30%, 4.59% and 1.05%, respectively. Compared with women with normoglycaemia, women with pregestational glucose at the diabetic level (≥7.0 mmol/L) might have a higher rate of macrosomia (6.18% vs 4.16%), whereas pregestational IFG seemed to be associated with reduced risks of many adverse outcomes, including spontaneous abortion, induced abortion due to medical reasons, PTB and LBW. After adjusting for potential confounders, pregestational diabetic hyperglycaemic was remained to be significantly associated with an increased risk of macrosomia (adjusted risk ratio 1.49, 95% CI 1.07 to 2.09). Abnormal maternal glucose levels before pregnancy (either hypoglycaemic or hyperglycaemic) seemed to have no significant negative effect on spontaneous abortion or induced abortion due to medical reasons.ConclusionAlthough without overt diabetes mellitus, women with once diabetic fasting glucose level during their preconception examinations could be associated with an increased risk for macrosomia. Uniform guidelines are needed for maternal blood glucose management during pre-pregnancy care to improve pregnancy outcomes.

Elevated thyroid stimulating hormone (TSH) is associated with an increased risk of spontaneous abortion (SA); however, the associated mechanism remains unclear. This study aimed to investigate the expression of microRNAs (miRNAs) and pathogenesis in the chorionic villi of TSH > 2.5 mIU/L-related SA patients. The chorionic villi were collected from pregnant women in the first trimester with TSH > 2.5 mIU/L with or without SA, as well as TSH < 2.5 mIU/L with or without SA to determine the level of miRNA expression. Differentially expressed miRNAs were confirmed by qRT-PCR in a total of 92 subjects. Cell counting kit-8 (CCK8), wound healing, transwell assays, and Western blotting were used to measure cellular biological functions and related protein in HTR-8/SVneo cells. The potential mechanisms were determined using a Luciferase reporter assay and rescue experiment. Compared with normal pregnant women, miR-17-5p was decreased and zinc finger protein 367 (ZNF367) was upregulated in the chorionic villi of TSH > 2.5 mIU/L-related SA patients. Using HTR-8/SVneo cells, we demonstrated that elevated TSH inhibited miR-17-5p expression, as well as trophoblast migration and invasion. The overexpression of miR-17-5p targeted and inhibited ZNF367 expression promoting the biological function of trophoblasts. Further studies confirmed that ZNF367 interference partially reversed the biological function of the miR-17-5p inhibitor on HTR-8/SVneo cells. Taken together, our results showed that miR-17-5p promoted biological function of trophoblasts by suppressing ZNF367.

Abstract STUDY QUESTION Is a maternal history of spontaneous abortion (SA) associated with an increased risk of attention-deficit/hyperactivity disorder (ADHD) in offspring? SUMMARY ANSWER Our results suggest an association between maternal history of SA and ADHD in offspring, with the risk increasing with the number of maternal SA and highest in the firstborn children whose mothers had had recurrent SAs after adjusting for a number of potential confounders. WHAT IS KNOWN ALREADY A history of SA has been associated with more complications in next pregnancies and adverse childbirth outcomes, which are risk factors for ADHD in the offspring. However, no previous study has investigated whether maternal SA increases risk of ADHD in the offspring. STUDY DESIGN, SIZE, DURATION This population-based study included all live-born children in Denmark from 1 January 1995 to 31 December 2012 (n = 1 062 667). All children were followed from 3 years of age until the day of ADHD diagnosis, death, emigration or 31 December 2016, whichever came first. PARTICIPANTS/MATERIALS, SETTING, METHODS There were 130 206 (12.2%) children born to mothers who had at least one SA. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). MAIN RESULTS AND THE ROLE OF CHANCE During a median follow-up of 9.4 years (interquartile range, 5.4–14.3), 25 747 children were diagnosed with ADHD. Overall, children of mothers with a history of SA had an increased rate of ADHD (HR, 1.11; 95% CI, 1.07 to 1.15). The HRs increased with the number of maternal SA, 1.09 (95% CI, 1.05 to 1.13) for one SA and 1.22 (95% CI, 1.12 to 1.33) for at least two SAs, respectively. These findings were consistent when we took into consideration a number of factors, such as maternal socioeconomic status, type of SA, birth order, parental history of psychiatric disorders, pregnancy characteristics and adverse birth outcomes. LIMITATIONS, REASONS FOR CAUTION Misclassification of SA was possible as we used population-based register data to capture maternal history of SA. However, any misclassification of maternal history of SA would be non-differential with regard to the diagnosis of ADHD in offspring, which generally leads to underestimation of the associations. Furthermore, probabilistic sensitivity analysis suggested that only 1% of change in the estimate may have been due to misclassification of SA. WIDER IMPLICATIONS OF THE FINDINGS SA is quite frequent (varying from 15 to 20%), and a small increase of neurodevelopmental problems in offspring could have major public health implications.

AbstractPregnancy and pregnancy loss may be associated with increased risk of diabetes in later life. However, the evidence is inconsistent and sparse, especially among East Asians where reproductive patterns differ importantly from those in the West. We examined the associations of pregnancy and pregnancy loss (miscarriage, induced abortion, and still birth) with the risk of incident diabetes in later life among Chinese women. In 2004–2008, the nationwide China Kadoorie Biobank recruited 302 669 women aged 30–79 years from 10 (5 urban, 5 rural) diverse localities. During 9.2 years of follow-up, 7780 incident cases of diabetes were recorded among 273,383 women without prior diabetes and cardiovascular disease at baseline. Cox regression yielded multiple-adjusted hazard ratios (HRs) for the risk of diabetes associated with pregnancy and pregnancy loss. Overall, 99% of women had been pregnant, of whom 10%, 53%, and 6% reported having a history of miscarriage, induced abortion, and stillbirth, respectively. Among ever pregnant women, each additional pregnancy was associated with an adjusted HR of 1.04 (95% CI 1.03; 1.06) for diabetes. Compared with those without pregnancy loss, women with a history of pregnancy loss had an adjusted HR of 1.07 (1.02; 1.13) and the HRs increased with increasing number of pregnancy losses, irrespective of the number of livebirths; the adjusted HR was 1.03 (1.00; 1.05) for each additional pregnancy loss. The strength of the relationships differed marginally by type of pregnancy loss. Among Chinese women, a higher number of pregnancies and pregnancy losses were associated with a greater risk of diabetes.

Introduction: Unsafe abortion is one of the major public health problems in developing countries including Nepal. After integration of comprehensive abortion care in safe motherhood service, there has been improvement in maternal and women health in Nepal. Furthermore, improvements are required in raising awareness and accessibility to safe abortion services to all the women in throughout the country. Methods: This is a retrospective study carried out in Western Regional Hospital after reviewing the data from the hospital records. Demographic details, parity, types of abortion for spontaneous abortion, and methods of induced abortion were noted and analyzed. Results: Maximum number of women belonged to 20-24 years of age and is Brahmin/Chhetri. Multi gravida are more than primi and they underwent induced abortion by medical termination of pregnancy. Similarly, incomplete abortion was in highest number among the spontaneous abortion. Conclusion: Easy availability of the safe abortion services and awareness among the people regarding it would certainly improve the maternal health and quality of life.

Abstract Background The safety profile of antimicrobials used during pregnancy is one important consideration in the decision on how to treat and provide postexposure prophylaxis (PEP) for plague during pregnancy. Methods We searched 5 scientific literature databases for primary sources on the safety of 9 antimicrobials considered for plague during pregnancy (amikacin, gentamicin, plazomicin, streptomycin, tobramycin, chloramphenicol, doxycycline, sulfadiazine, and trimethoprim-sulfamethoxazole [TMP-SMX]) and abstracted data on maternal, pregnancy, and fetal/neonatal outcomes. Results Of 13 052 articles identified, 66 studies (case-control, case series, cohort, and randomized studies) and 96 case reports were included, totaling 27 751 prenatal exposures to amikacin (n = 9), gentamicin (n = 345), plazomicin (n = 0), streptomycin (n = 285), tobramycin (n = 43), chloramphenicol (n = 246), doxycycline (n = 2351), sulfadiazine (n = 870), and TMP-SMX (n = 23 602). Hearing or vestibular deficits were reported in 18/121 (15%) children and 17/109 (16%) pregnant women following prenatal streptomycin exposure. First trimester chloramphenicol exposure was associated with an elevated risk of an undescended testis (odds ratio [OR] 5.9, 95% confidence interval [CI] 1.2–28.7). Doxycycline was associated with cardiovascular malformations (OR 2.4, 95% CI 1.2–4.7) in 1 study and spontaneous abortion (OR 2.8, 95% CI 1.9–4.1) in a separate study. First trimester exposure to TMP-SMX was associated with increased risk of neural tube defects (pooled OR 2.5, 95% CI 1.4–4.3), spontaneous abortion (OR 3.5, 95% CI 2.3–5.6), preterm birth (OR 1.5, 95% CI 1.1–2.1), and small for gestational age (OR 1.6, 95% CI 1.2–2.2). No other statistically significant associations were reported. Conclusions For most antimicrobials reviewed, adverse maternal/fetal/neonatal outcomes were not observed consistently. Prenatal exposure to streptomycin and TMP-SMX was associated with select birth defects in some studies. Based on limited data, chloramphenicol and doxycycline may be associated with adverse pregnancy or neonatal outcomes; however, more data are needed to confirm these associations. Antimicrobials should be used for treatment and PEP of plague during pregnancy; the choice of antimicrobials may be influenced by these data as well as information about the risks of plague during pregnancy.

Background: Patient who had history of spontaneous abortion in her previous pregnancy is associated with adverse outcome in her present pregnancy.Methods: A total 63 pregnant women attending OPD and admitted in department of obstetrics and gynecology, Yenepoya Medical College, from April 2017 to September 2017, considered and outcome were studied.Results: Out of 63 patient’s majority (57.1%) of patients belong to the age group 21-29 year. Anemia was found to be very severe in 4.3%, severe in 10% and moderate in 30% patients. Maximum patients (45.7%) were with history of previous one abortion followed by previous two abortions (38.6%). The final outcomes were term livebirth 47 (74.3%), abortion 9 (14.3%), preterm delivery 5 (8.6%), and stillbirth 2 (2.8%) caesarean section (23.3%) for various indications. 19.23% had term PROM, 9.09% had PPROM, 5.76% had term IUGR, 3.84% term IUD, preterm IUD accounts for 9.09% and still birth accounted for about 1.92% which was term, pre-eclampsia accounted for 4.76%, malpresentation for 7.93%, total 3 cases of antepartum hemorrhage out of which  placenta previa accounts for about 3.1% and abruption for 1.58%, manual removal of placenta 4.7% and low birth weight 7.6%.Conclusions: Previous history of spontaneous abortion is associated with adverse pregnancy outcome. There is increased risk of abortion, preterm delivery, need for caesarean sections and fetal loss which can be reduced by booking and giving antenatal care.

Objective. To determine whether there is a difference in intraoperative bleeding with inhalational versus noninhalational anesthetic agents for patients undergoing suction dilatation and curettage for first-trimester induced abortion.Methods. This is an IRB-approved retrospective chart review of the electronic medical records of patients undergoing induced abortion at gestational ages between 5 0/7 and 14 0/7 weeks of pregnancy at the New York City Health + Hospitals/Metropolitan. The records of 138 patients who underwent suction dilatation and curettage for induced abortion between June 2012 and June 2014 were reviewed for an association between anesthetic technique and intraoperative hemorrhage. Twenty patients received inhalational anesthetic agents, while 118 received intravenous anesthetics. Blood loss was estimated by the operating gynecologists.Results. The mean intraoperative blood loss for inhalational anesthetics (113.6 ml) was significantly higher than with noninhalational agents (40.2 ml) (p=0.007). Age, body mass index, and gestational age were not statistically different between the groups; the number of methylergonovine doses at induced abortion trended higher with inhalation anesthetics.Conclusions. The difference in blood loss between the two types of anesthetic techniques was statistically significant. These findings may be important for patients with significant anemia or at an increased risk of bleeding, such as those with unrecognized coagulopathies.
