Aim: The purpose of this study was to determine the normal length of the brainstem (BS) in Korean fetuses and to evaluatethe usefulness of the routine measurement of BS size in the first trimester of pregnancy for the early detection of spina bifida.Material and methods: A total of 2,621 normal singleton pregnant Korean women at 10+6 to 13+6 weeks of gestation were selected for this retrospective cross-sectional study. Ultrasonography was used to measure the length of the longest vertical depth diameter of the BS and brainstem-occipital bone (BSOB) in order to obtain the BS to BSOB ratio.Results: The best indicators for spina bifida ranged from 1.00±0.24 mm to 4.70±0.46 mm for the BS and from 2.90±0.36 mm to 8.50±0.92 mm for the BSOB. For the gestational period, BS (R=0.70) and BSOB (R=0.81) values were considered statistically significant (p<.0001). The value of the BS to BSOB ratio was <1.0 in normal fetuses, and was not correlated with the gestational age.Conclusion: Measurement of BS and BSOB diameter in the first trimester is thought to provide the best reference marker for evaluating the posterior brain for diagnosis of spina bifida.

Background: Thyroid disorders in pregnancy are common and are associated with adverse maternal, fetal and neonatal effects. When the prevalence of thyroid disorders is high, then screening for thyroid disorders in early pregnancy can help improve the obstetrical outcome.Methods: Five hundred and fifty women in their first trimester of pregnancy were studied. They were investigated for estimation of free triiodo thyronine (FT3), free thyroxine (FT4) and thyroid stimulation hormone (TSH). The upper normal limit for TSH considered was 4.0 mIU/L.Results: Prevalence of thyroid disorders in the study was 12.6%. Hypothyroidism (12%) was more common than hyperthyroidism (0.6%). Subclinical hypothyroidism was present in 10%.Conclusions: Screening of thyroid disorders is to be considered for all pregnant women. As the prevalence of thyroid disorders is high, early recognition and treatment shall reduce maternal and fetal morbidity.

Aim: To evaluate and assess the prevalence along with its related complications of subclinical hypothyroidism in pregnant ladies during the 1st trimester of pregnancy in Pakistani population. Study design: Cross sectional study Place and duration of study: Department of Medicine, Unit-1 of Lahore General Hospital, Lahore, Pakistan from 11th February 2019 to 29th December 2019. Methodology: Four hundred and fifty seven pregnant women with a gestational age up to 12th week with an age group between 18-45 years were included in this study. Blood samples were collected for free triiodothyronine, free thyroxine and thyroid stimulating hormone levels. Patients were regularly followed at an interval of 4 weeks for their entire pregnancy period. Adverse events and complications were noted. Results: One hundred and sixty nine subjects had TSH levels above the normal range i.e., 4.6-10mIU/L. 288 subjects were having TSH below 4 mIU/L levels. The overall prevalence of subclinical hypothyroidism (SCH) was found to be 37% in pregnant women during their first trimester of pregnancy. Pregnant women having subclinical hypothyroidism (SCH) were having higher risks of loss of pregnancy, abruptio placentae and neonatal death rates as compared to euthyroid pregnant women. Conclusion: Higher prevalence of subclinical hypothyroidism (SCH) in the first trimester of pregnancy indicates that these women are at increased risks of loss of pregnancy, placental abruption and neonatal death as compared to euthyroid pregnant women.

Background: Thyroid dysfunction is associated with negative pregnancy outcomes. There is a lack of reliable information on thyroid hormones in Iranian pregnant women, especially in Yazd. Objective: To determine the safe thyroid hormone levels in women of Yazd and also the first trimester-specific reference ranges for serum thyroid-stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). Materials and Methods: In this cross-sectional study, the serum of 1,148 women in the first trimester of pregnancy was analyzed. Thyroid function tests (TSH, T4, T3) were measured through radioimmunoassay (RIA) [immunoradiometric (IRMA) for TSH]. The study was conducted in Yazd, from September 2018 to November 2019. Reference intervals were defined as the 5th, 50th, and 95th percentiles. Results: The mean age of the participants was 28.78 (± 5.86 yr) (range: 15-45 yr). The thyroid hormones reference intervals in the first trimester were TSH (0.2-3.8 mIU/l), T4 (7.45-12.75, μg/dl), and T3 (100-217 ng/dl). Conclusion: The results of the present study determined a local thyroid function measurement in the first trimester of pregnancy at a center of Yazd, Iran. This could facilitate the decision-making of maternal TSH level during the first trimester of pregnancy. Key words: First pregnancy trimester, Thyrotropin, Thyroxine, Triiodothyronine.

Objective To analyze pelvic floor muscle strength (PFMS), urinary continence and quality of life related to urinary incontinence (UI) of women in the first trimester of pregnancy. Method Cross-sectional study with a sample of 500 women who started prenatal care in a complementary healthcare facility in Guarulhos, state of São Paulo, from 2012 and 2013. Pelvic floor muscle strength was evaluated through perineometry. The pregnant women who presented UI answered the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Results It was found that maternal age (OR=1.06; CI95% 1.02-1.11) and prior UI (OR=15.12; 95%CI 8.19-27.92) are the variables that, in tandem, best explain the occurrence of UI at the beginning of pregnancy. The mean score on the ICIQ-SF was 8.2 (SD=3.9), considered a moderate impact on quality of life. Conclusion Older pregnant women with prior UI are more likely to have UI in the first trimester of pregnancy.

Background: Antibiotic use in pregnant women at the national level has rarely been reported in China. Objectives: We aimed to investigate antibiotic prescriptions during pregnancy in ambulatory care settings in China. Methods: Data of 4,574,961 ambulatory care visits of pregnant women from October 2014 to April 2018 were analyzed. Percentages of Antibiotic prescriptions by different subgroups and various diagnosis categories and proportions of inappropriate antibiotic prescriptions for different subgroups were estimated. Food and Drug Administration (FDA) pregnancy categories were used to describe the antibiotic prescription patterns. The 95% confidence intervals (CIs) were estimated using the Clopper––Pearson method or Goodman method. Results: Among the 4,574,961 outpatient visits during pregnancy, 2.0% (92,514 visits; 95% CI, 2.0–2.0%) were prescribed at least one antibiotic. The percentage of antibiotic prescriptions for pregnant women aged >40 years was 4.9% (95% CI, 4.7–5.0%), whereas that for pregnant women aged 26–30 years was 1.5% (95% CI, 1.4–1.5%). In addition, percentages of antibiotic prescriptions varied among different trimesters of pregnancy, which were 5.4% (95% CI, 5.3–5.4%) for the visits in the first trimester of pregnancy and 0.5% (95% CI, 0.4–0.5%) in the third trimester of pregnancy. Furthermore, the percentages of antibiotic prescriptions substantially varied among different diagnosis categories and nearly three-quarters of antibiotic prescriptions had no clear indications and thus might be inappropriate. In total, 130,308 individual antibiotics were prescribed; among these, 60.4% (95% CI, 60.0–60.8%) belonged to FDA category B, 2.7% (95% CI, 2.1–3.5%) were classified as FDA category D and 16.8% (95% CI, 16.2–17.4%) were not assigned any FDA pregnancy category. Conclusions: Antibiotic prescriptions in ambulatory care during pregnancy were not highly prevalent in mainland China. However, a substantial proportion of antibiotics might have been prescribed without adequate indications. Antibiotics whose fetal safety has not been sufficiently illustrated were widely used in pregnant women.

Abstract Background Preeclampsia has the greatest impact on maternal mortality which complicates nearly a tenth of pregnancies worldwide. It is one of the top five maternal mortality causes and responsible for 16 % of direct maternal death in Ethiopia. Little is known about the level of knowledge and attitude towards preeclampsia in Ethiopia. This study was designed to assess the knowledge and attitude towards preeclampsia and its associated factors in South Gondar, Northwest Ethiopia. Methods A multicenter facility-based cross-sectional study was implemented in four selected hospitals of South Gondar Zone among 423 pregnant women. Multistage random sampling and systematic random sampling techniques were used to select the study sites and the study participants respectively. Data were entered in EpiData version 3.1 while cleaned and analyzed by Statistical Package for Social Sciences (SPSS) version 23. Descriptive and inferential statistics were performed. Adjusted odds ratio with 95 % confidence interval were used to identify the significance of the association between the level of knowledge on preeclampsia and its predictors. Results In this study, 118 (28.8 %), 120 (29.3 %) of the study participants had good knowledge and a positive attitude towards preeclampsia respectively. The likelihood of having good knowledge on preeclampsia was found to be low among women with no education (AOR = 0.22, 95 % CI (0.06, 0.85)), one antenatal care visit (ANC) (AOR = 0.13, 95 % CI (0.03, 0.59)). Whereas, those who booked for ANC in the first trimester (AOR = 6.59, 95 % CI (1.43, 30.33)), gave the last birth at a health facility (AOR = 2.61, 955 CI (1.03, 6.61)), and experienced a complication during previous births (AOR = 3.67, 95 % CI (1.78, 7.57)) were more likely to be knowledgeable on preeclampsia. Conclusions No formal education and not attending four ANC visits were associated with poor knowledge of preeclampsia. While participants who visited health facilities during the first trimester, who gave birth at health facilities, and those who experienced a complication in previous births were more likely to be knowledgeable on preeclampsia. Improving the numbers of ANC visits and encouraging facility delivery are important measures to improve women’s knowledge on preeclampsia. Health education regarding preeclampsia risk factors, symptoms, and complications shall be emphasized.
