Maternal mortality due to valvular heart disease: a population-based study in Turkey.

BACKGROUND/AIM: To assess the clinical and demographic features of maternal mortality cases among patients with cardiac valvular diseases between 2012 and 2019. METHODS: Maternal mortality due to valvular heart disease between January 2012 and December 2019 in Turkey was retrospectively analyzed. The cases were classified according to New York Heart Association (NYHA) classification based on the severity of the heart disease. NYHA classification groups were divided into two; as class I-II (n = 34) and class III-IV (n = 31). Two groups were compared in terms of demographic and clinical characteristics. RESULTS: Valvular heart disease was diagnosed in 41 (63.1%) of the cases before pregnancy. It was found that 100% (n = 21) of the warfarin users had switched to low molecular weight heparin treatment due to concerns about warfarin embryopathy after the diagnosis of pregnancy, and only 14.2% (n = 3) of them had been monitorized with Antifactor Xa activity to evaluate the effectiveness of the medication. Two NYHA groups had similar clinical characteristics. Intensive care unit admission rate, frequency of prosthetic valve, rate of thromboprophylaxis, type of valvular disease and reasons of maternal death were similar between the NYHA groups (p < 0.05). CONCLUSION: Maternal mortality may be observed in cases with NYHA class I-II in almost similar rates with NYHA class III-IV. Therefore, it is crucial to adequately assess the mortality risk of pregnant women with cardiac valvular pathologies and to achieve early diagnosis and appropriate treatment in order to reduce maternal mortality.

Effects of the COVID-19 pandemic on perinatal outcomes: a retrospective cohort study from Turkey.

BACKGROUND: Lockdowns, pregnant women's fear from hospitalization in addition to uncertainties about appropriate birthing practices at the beginning of the pandemic may have affected the health outcomes of mother-infant couples. We aimed to explore whether pregnancy outcomes including the rates of cesarean delivery (CS), preterm, and low birth weight (LBW) births have changed during the pandemic period compared with the pre-pandemic period. METHODS: We applied a population-based retrospective cohort, before-after approach in 2020 vs. similar calendar months in 2019 for five periods [Jan-Feb (pre-pandemic); March-May (1st wave and lockdown); June-August; September-October; November-December (2nd wave and lockdown)]. The data was modelled through multiple logistic regressions using key outcomes; CS, preterm, and LBW births as the dependent variables, and adjustments were made for independent variables in SPSS software. We evaluated the modification of years by periods by adding interaction term (yearXperiod) to the model. RESULTS: The rate of CS in hospital births increased from 57.7% in 2019 to 60.2% in 2020. CS rates were significantly increased during the 3rd and 4th periods. The overall preterm rate was 11%. When singleton pregnancies were considered, adjusted multivariable analyses showed a decrease in preterm proportions during all time periods with respect to the pre-pandemic period. The percentage of LBW was 7.7% during the pandemic period and was found to be significantly reduced compared to the pre-pandemic period. There was a significant reduction in LBW rates in all periods except the second lockdown period. CONCLUSIONS: Our findings suggested significant reductions in preterm and LBW births possibly due to the indirect effects of the pandemic. Moreover, strategies need to be considered to address the increased CS rates and shifting of maternity service utilization to private facilities.

Maternal deaths with epilepsy: A population-based study in Turkey.

OBJECTIVE: To evaluate the clinical characteristics of maternal deaths with epilepsy in Turkey. STUDY DESIGN: This epidemiological population-based study was conducted on all consecutive early maternal deaths with epilepsy in Turkey from 2012 to 2019. Maternal deaths accompanied by epilepsy as a comorbidity (n = 13) were evaluated separately. Epilepsy related maternal deaths were divided into two groups: 1) status epilepticus (n = 19) and 2) Sudden unexpected death in epilepsy (n = 19). Two groups were compared in terms of demographic features and clinical characteristics. RESULTS: Maternal deaths with epilepsy ranged between 2.5 % and 5.3 % among total maternal deaths. Pulmonary embolism (32 %), cerebrovascular event (23 %), and cerebral vein thrombosis (15.4 %) were the leading mortality reasons in maternal deaths accompanied by epilepsy. Epilepsy duration, the time interval between pregnancy and the last epileptic seizure, compatibility with medication, rates of preconceptional counseling, and regular antenatal follow-up were all significantly higher in the sudden unexpected death in epilepsy group. The perinatal complication rate was significantly higher in the status epilepticus group (p > 0.05). CONCLUSION: Physicians who deal with pregnant women with epilepsy should be attentive for severe complications and the increased risk of maternal mortality in these cases should be kept in mind.

The Incidence of Cystic Fibrosis in the Central Region of Anatolia in Turkey Between 2015 and 2016

Background: Cystic fibrosis is the most common metabolic chronic disease among European Caucasian children. Cystic fibrosis incidence in Northern Europeans countries is approximately 1 in 3000 births while the worldwide prevalence varies considerably. Aims: To determine the incidence of cystic fibrosis in the central region of Anatolia in Turkey using the newborn screening program data. Study Design: Cross-sectional study Methods: We used the records of the newborn screening program which is implemented by the Konya and Kayseri Provincial Health Directories. Between January 2015 and December 2016, there were a total of 119006 live births in Konya and Kayseri. The newborn screening test was applied to all these babies. Results: During this period, there were 22 live born babies diagnosed with cystic fibrosis in Konya with an incidence of 2.9 per 10000 live births and 13 live born babies diagnosed with cystic fibrosis in Kayseri with an incidence of 2.8 per 10000 live births. In genetic of 30 patients, fifteen patients were homozygous, and 15 patients were a compound heterozygote. Twenty-one different gene variants were detected and the most common mutation was F508del (17/30). Conclusion: We found the incidence of cystic fibrosis in central Anatolia similar to northern European countries.
