RESUMEN
PURPOSE: To investigate the effects of laboratory-confirmed SARS-CoV-2 infection on thyroid function tests (TFTs) in pregnant women and to evaluate whether TFT changes are related to the severity and prognosis. METHODS: Consecutive pregnant women tested for SARS-CoV-2 by RT-PCR at Ankara City Hospital were recruited between January 2021 and September 2021. Thyroid-stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3), thyroid peroxidase antibody (anti-TPO), and thyroglobulin antibody (anti-TG) were measured on admission. RESULTS: Among 747 eligible pregnant women with the same baseline characteristics, 369 RT-PCR-positive women in the patient group and 378 RT-PCR-negative women in the control group were included in the analyses. Pregnant women in the patient group had significantly lower TSH, FT4, FT3, Anti TPO, and Anti TG concentrations compared with those in the control group (p < 0.001). The proportion of patient groups with mild, moderate, severe, and critical diseases were 297 (80.4%), 40 (10.8%), 17 (4.6%), and 15 (4.2%), respectively, among which with the moderate, severe, and critical disease had significantly lower FT3 values (2.5 vs 2.19 pg/mL, p < 0.001) and higher nonthyroidal illness syndrome (NTIS) (29.2 vs. 8.4%, p < 0.001) than those with mild disease. Lower FT3 values increased the risk of ICU admission, NICU admission, and severe disease (p < 0.001). FT3 and TSH correlated positively with lymphocytes (p < 0.001) and negatively correlated with C-reactive protein (CRP) (p < 0.001, p = 0.005). CONCLUSION: The SARS-CoV-2 infection seems to have an impact on the TFTs of pregnant women, and particularly FT3 level seems to be correlated with disease severity.

BACKGROUND: Despite the great advances in Assisted Reproductive Technologies (ART), management of poor responders has remained a great challenge. Gonadotropin releasing hormone antagonist (GnRH-ant) has been offered as a patient friendly protocol. In the literature, conflicting data exists about the effect of the GnRH-ant starting day on cycle outcomes. AIM: The aim of this study is to evaluate the effect of GnRH-ant starting day on cycle outcomes of patients with poor ovarian response defined by Bologna criteria. SETTING AND DESIGN: This retrospective cohort study was conducted at an ART clinic of a tertiary hospital. MATERIALS AND METHODS: A total of 361 cycles using flexible GnRH-ant, 195 in Group A (GnRH-ant administered before day 6 of stimulation) and 166 cycles in Group B (GnRH-ant started on or after day 6), were selected retrospectively for the study. STATISTICAL ANALYSIS: Statistical analysis of data was carried out using using IBM SPSS Statistics Software (20.0, SPSS Inc., Chicago, IL, USA). Independent samples t-test and Mann-Whitney U test were used to analyze the variables. RESULTS: Total antral follicle count was significantly higher in Group A compared to Group B (P = 0.009). Duration of stimulation was significantly shorter (P < 0.01) and total dose of gonadotropin used was lower in Group A when compared to Group B (P < 0.01). While higher number of oocytes was retrieved from Group A (P = 0.037), no between-group differences were observed in number of mature oocytes, fertilized oocytes, clinical pregnancy rate or ongoing pregnancy rate (OPR) per embryo transfer (P > 0.05). CONCLUSION: Early GnRH-ant start may point out a favourable response to ovarian stimulation in poor responders. However, clinical or OPRs were not different from the late GnRH-ant start group.
RESUMEN
Objective: Glucagon-like peptide 1 (GLP-1), a gut-derived peptide has been reported to have insulin-like effects. Our aim is to examine GLP1 levels in hyperemesis gravidarum (HEG). Materials-methods: The study population consisted of 2 groups: Group 1 (control subjects) consisted of 22 women with uncomplicated singleton pregnancies in the first trimester. Group 2 consisted of 22 singleton pregnancies complicated by HEG. Glucose and GLP1 levels were determined. Enzyme-linked Immunosorbent Assay Kit for Glucagon like Peptide 1 (GLP1) was used (Uscn, Life Science Inc.). Results: No significant differences in maternal age, gestational age and gravida were observed between hypermetric and control groups. Maternal serum GLP1 levels were significantly higher in HEG compared with control group (P = 0.004). Conclusion: The results of our study revealed that the presence of increased GLP1 levels in women with HEG could contribute to the pathogenesis of the disease. Our results indicated that increased GLP1 levels may be associated with hyperemesis gravidarum. The limitation of our study was the restricted number of patients. Large prospective and randomized studies are required to evaluate the effect of GLP1 levels on hyperemesis gravidarum.
RESUMEN
: Thrombocytopenia is defined as a platelet count less than 150â000/µl and it is the most common hematologic disease after anemia in pregnancy. This study aims to investigate pregnant women with severe thrombocytopenia (platelet count <50â000/µl). In the relevant literature, few studies have addressed severe thrombocytopenia in pregnancy. This is a retrospective study based on the data from a reference center in Ankara, Turkey between January 2016 and December 2017. The study group consisted of 51 pregnant women who had two platelet counts lower than 50â000/µl. Descriptive statistical methods were utilized to analyze the results. The study analyzed the causes of severe thrombocytopenia, maternal and fetal-neonatal outcomes, and the management of the patients. The common causes of severe thrombocytopenia were hypertensive disorders (66.7%), immune thrombocytopenia (13.7%), massive obstetric hemorrhage (7.8%), and disseminated intravascular coagulation (5.9%). The preterm delivery occurred in 58.8% of the patients, and 46 live-births (two twins), six stillbirths, and one pregnancy termination emerged. Postpartum hemorrhage occurred in four (0.08%) patients, and blood transfusion was performed in 15 (29.4%) patients. The platelet transfusion was required to increase the platelet count of 30 (58.8%) patients. The study showed that the incidence of causes in severe thrombocytopenia in pregnancy varied considerably from mild and moderate thrombocytopenia. Despite severe thrombocytopenia, maternal and neonatal bleeding complications were infrequent in the study group.

We aimed to evaluate the association of fetal aortic isthmus (AoI) Doppler flow measurements in intrauterine growth-restricted (IUGR) fetuses with fetal outcome. The data presented in this prospective cohort study were obtained from 74 IUGR and 71 appropriate-for-gestational-age (AGA) fetuses of singleton pregnancies with normal medical and obstetric histories that were between 26 and 40 weeks of gestation. All AoI Doppler scans were performed by the same observer. There were no statistical differences in maternal characteristics and gestational age or between AGA and IUGR fetuses at the inclusion time. No cases of reversed flow during diastole were detected. Aortic isthmus flow index was increased in growth-restricted fetuses. Absolute end-diastolic (EDV) and time-averaged maximum velocities were decreased in the IUGR fetuses. There was an association between AoI Doppler EDV measurements and prediction of neonatal intensive care unit requirement as well as AoI Doppler isthmic flow index and resistance index measurements and low 5-minute Apgar values. Aortic isthmus EDV was found to be independently associated with IUGR status. Because the AoI Doppler flow measurements of the IUGR fetuses were different from the AGA fetuses and predicted neonatal adverse outcome, Doppler imaging of the AoI could be used as a screening tool in the clinical surveillance of fetuses with IUGR after confirmation in larger prospective studies.

OBJECTIVE: The present study aimed to investigate perinatal outcomes and to describe antenatal factors for development of preeclampsia (PE) in patients with isolated proteinuria in pregnancy. METHODS: This retrospective case control study consisted of patients with isolated proteinuria between 2009 and 2014. The patients were considered as gestational proteinuria (GP) (group 1, n: 35) if they remain normotensive. Patients who develop PE after onset of proteinuria were allocated into group 2 (n: 19). Perinatal outcomes of patients in each group were compared. Logistic regression analysis was performed to detect antenatal risk factors for PE. RESULTS: The rate of small for gestational age (SGA) fetuses was higher in patients with isolated proteinuria than control group. In the logistic regression model, maternal age and completed gestational weeks at onset of proteinuria decreased the risk of PE in multivariate analysis (OR: 0.849 (95% CI: 0.731-0.986), OR: 0.732 (95% CI: 0.594-0.902) respectively). Systolic BP at onset of proteinuria, however, was associated with an independently increased risk of PE (OR: 1.181 (95% CI: 1.046-1.333)). CONCLUSION: Maternal clinical characteristics, but not laboratory features may help to predict development of PE.
RESUMEN
INTRODUCTION: This study aimed to document the prevalence of syphilis among pregnant women in Turkey. METHODOLOGY: In this retrospective cohort study, a total of 63,276 sera obtained between January 2007 and June 2014 from women who were routinely screened for syphilis as a part of antenatal care at a tertiary referral hospital in Turkey were analyzed. Serological screening was done with the rapid plasma reagin (RPR) test on venous blood samples. Treponema pallidum hemagglutination assay (TPHA) was the confirmation test for the diagnosis of syphilis in patients who had positive results in the screening test. RESULTS: Between 2007 and the first six months of 2014, 41 RPR+ and only five confirmed syphilis-positive patients were determined. The syphilis seroprevalence rate was 0.0648%. Within these years, there was no case of congenital syphilis detected in the hospital. CONCLUSION: As there is evidence of effective screening of syphilis contributing to the effective treatment and prevention of adverse outcomes, routine antenatal screening of syphilis is recommended. The rationale depends on the consideration of the serious results of not treating the disease and the cost effectiveness of screening.

OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) remains as a clinical problem for hyperresponder patients during controlled ovarian hyperstimulation and in vitro fertilization (COH-IVF) procedure. Herein, we aimed to evaluate the COH-IVF outcomes in hyperresponder patients managed with coasting treatment strategy for OHSS prevention regarding the establishment of clinical pregnancy as an endpoint of the treatment cycle. MATERIALS AND METHODS: The medical records related to the COH-IVF outcome in 119 hyperresponder patients who have exhibited a serum estradiol level greater than or equal to 3000 pg/mL were evaluated. The study was conducted on a total of 119 patients, 98 of whom have been treated by coasting or coasting with GnRH antagonist co-treatment strategies, while the remaining 21 women (control group) have not been managed with coasting treatment. The COH and IVF-ET outcomes in the 119 patients were compared based on the coasting treatment situation. RESULTS: Among the women who received coasting treatment, the number of patients demonstrating E2 level decrement and also E2 level decrement rate after coasting were similar between patients with and without clinical pregnancy. Total gonadotropin dose, 2PN number, embryo number, and fertilization rate were significantly higher in the patients with a clinical pregnancy. CONCLUSION: The coasting treatment is a clinically useful preventive strategy for OHSS avoidance. GnRH antagonist co-treatment decreases the duration of coasting although any detrimental or ameliorating impact of this effect on pregnancy rates have not been seen. The E2 level decrement or increment following coasting treatment seems not to be related to cycle outcomes.
