The assessment of twin pregnancies delivered in our clinic: three-year experience

Objective: Twin pregnancies constitute 1–2% of all pregnancies. With the recent developments in assisted reproductive technologies, the incidence of multiple pregnancy has increased. Preterm labor is held responsible for the poor neonatal outcomes primarily. In our study, we aimed to assess fetal-maternal outcomes of twin pregnancies seen in our clinic. Methods: One hundred and thirty twin pregnancy cases out of 4241 pregnant women who delivered in our clinic between 01.01.2017 and 01.01.2020 were included in the study. The labor records of the patients were reviewed retrospectively and their data for age, week of gestation, delivery type, birth weight, fetal sex, chorionicity characteristics and laboratory parameters were recorded. Definitive statistics and SPSS 21.0 for statistical analyses were used to evaluate the data obtained from the study. The data were presented as mean ± SD (standard deviation). Results: The incidence of twin pregnancy was found 3%. In the ultrasonographic imaging evaluated during diagnosis, 27.7% of the cases were monochorionic and 72% of them were dichorionic. Of the pregnant women, 12.3% were at term and 87.7% were at preterm period. When the preterm fetuses were evaluated, 37.7% of 114 preterm fetuses were delivered at late preterm period, 29.2% of them at mid-preterm period and 20.8% at premature preterm period. The rates of treatment pregnancy (pregnancy provided by ovulation induction and assisted reproductive technologies) and spontaneous twin pregnancy were 20% and 80%, respectively. Mean maternal age was found 31.3. When evaluated in terms of maternal morbidity, preterm labor and premature rupture of membrane were the most common problems. Mean newborn weight was 1832g and 59.3% of the newborns had low birth weight and 21.8% of them had very low birth weight. While one fetus had transverse presentation in 12.5% of the patients, at least one fetus had breech presentation in 53.1% of the cases and 34.4% of the cases had head-head presentation. Conclusion: Twin pregnancies are characterized by the increased feto-maternal risks. Therefore, both antenatal and intrapartum management should be maintained diligently

The assessment of maternal deaths between 2015 and 2020 in Elazığ, Turkey

Objective: To determine the maternal deaths and the factors affecting them in our city. Methods: The maternal deaths occurred in our city between January 2015 and June 2020 were reviewed retrospectively. The review was conducted by checking “Maternal Death Registry Forms” of the Provincial Directorate of Health. In cases where additional data related with the cause of death were required, the relatives of the cases, associated family practitioner, The Council of Forensic Medicine or local authorities were contacted. The data of the cases including age, gravida, parity, abortion, delivery type, week of gestation during delivery, period of death and maternal deaths due to direct, indirect and incidental causes were recorded. Based on total live births and maternal deaths within 6.5 years, maternal mortality rate was found as the maternal death number per 100,000 live births. Descriptive statistics were used for the statistical analysis of the data. Results: A total of 46.618 live births occurred between 2015 and 2020 in Elazığ. The number of maternal deaths due to direct and indirect causes is 7, and maternal mortality rate was found 15.01/100,000. Hypertensive diseases during pregnancy (n=3, 42.8%), pulmonary embolism (n=1, 14.3%) and cerebral thrombosis (n=1, 14.3%) were among the natural causes of maternal deaths. Indirect cause for maternal death was cardiac diseases (n=2, 28.6%). When they were categorized according to the Three Delays Model, there were 3 death cases in the first delay model and 2 death cases in the third delay model, but there was no maternal death in the second delay model. Conclusion: Maternal death is an significant public health issue which develops due to the generally preventable causes and maintains its importance. The factors contributing to death should be paid attention in order to decrease maternal death rates

Comparison of the efficacy between bilateral proximal tubal occlusion and total salpingectomy on ovarian reserve and the cholinergic system: an experimental study

Background and aim: To compare the effects of bilateral proximal tubal occlusion and bilateral total salpingectomy on ovarian reserve and the cholinergic system via rat experiment. Materials and methods: Twenty-one adult female rats were randomly divided into the following three groups: G1 (n = 7), sham group; G2 (n = 7), bilateral total salpingectomy group; and G3 (n = 7), bilateral proximal tubal occlusion group. Four weeks later, the abdomen of the rats was opened. The right ovarian tissues were stored in 10% formaldehyde, whereas the left ovarian tissues were stored at –80 °C in aluminum foil. Serum samples were evaluated for antimullerian hormone. The right ovary was used for histological and immunoreactive examination, and the left ovary was used for tissue MDA analysis. Tissue samples were analyzed for MDA levels with spectrophotometric measurement, apoptosis with TUNEL staining, fibrosis score with Mason trichrome staining, ovarian reserve with HE staining, and cholinergic receptor muscarinic 1 (CHRM1) level with immunoreactivity method. Results: Compared to G1 and G3, the number of corpus luteum with secondary follicles was significantly lower in G2, whereas the number of ovarian cysts and fibrosis and apoptosis scores increased significantly. The CHRM1 immunoreactivity was significantly lower in G2 than in G1 and G3. Conclusions: Compared to the bilateral proximal tubal occlusion performed by using bipolar cautery, bilateral total salpingectomy in rats leads to a significant damage in ovarian histopathology and the cholinergic system

A Simple Strategy to Decrease Fatal Carotid Blowout Syndrome After Stereotactic Body Reirradiaton for Recurrent Head and Neck Cancers

Background This study aimed to compare the therapeutic outcomes and fatal carotid blow out syndrome (CBOS) incidence rates between two different stereotactic body radiotherapy (SBRT) protocols. Methods The study included 75 patients with inoperable locally recurrent head and neck cancer treated with SBRT in our department between June 2007 and March 2011. The first 43 patients were treated sequentially (group I). Then our SBRT protocol was changed due to the high rate of CBOS, and the following 32 patients were treated every other day in a prospective institutional protocol (group II). Results Median overall survival in group I and group II was 11 months and 23 months, respectively (P = 0.006). We observed 11 cases of CBOS. Only 1 of 7 patients (14%) with CBOS survived in group I, whereas 2 of 4 patients (50%) in group II remain alive. CBOS free median overall survivals were 9 months, and 23 months in group I and group II respectively (P = 0.002). The median radiation dose received by the carotid artery in patients with CBOS was 36.5 Gy (range: 34–42.8 Gy), versus 34.7 Gy (range: 0–44 Gy) in the patients that didn’t have CBOS (P = 0.15). CBOS did not occur in any of the patients with a maximum carotid artery radiation dose <34 Gy. Conclusions Every other day SBRT protocol for re-irradiation of recurrent head and neck cancer is promising in terms of decreasing the incidence of fatal CBOS.PubMedWoSScopu

The Impact of CoronaVac Vaccination on 28-day Mortality Rate of Critically Ill Patients with COVID-19 in Türkiye

Background:Vaccines against coronavirus disease-19 (COVID-19) have been effective in preventing symptomatic diseases, hospitalizations, and intensive care unit (ICU) admissions. However, data regarding the effectiveness of COVID-19 vaccines in reducing mortality among critically ill patients with COVID-19 remains unclear.Aims:To determine the vaccination status and investigate the impact of the COVID-19 vaccine on the 28-day mortality in critically ill patients with COVID-19.Study Design:Multicenter prospective observational clinical study.Methods:This study was conducted in 60 hospitals with ICUs managing critically ill patients with COVID-19. Patients aged ≥ 18 years with confirmed COVID-19 who were admitted to the ICU were included. The present study had two phases. The first phase was designed as a one-day point prevalence study, and demographic and clinical findings were evaluated. In the second phase, the 28-day mortality was evaluated.Results:As of August 11, 2021, 921 patients were enrolled in the study. The mean age of the patients was 65.42 ± 16.74 years, and 48.6% (n = 448) were female. Among the critically ill patients with COVID-19, 52.6% (n = 484) were unvaccinated, 7.7% (n = 71) were incompletely vaccinated, and 39.8% (n = 366) were fully vaccinated. A subgroup analysis of 817 patients who were unvaccinated (n = 484) or who had received two doses of the CoronaVac vaccine (n = 333) was performed. The 28-day mortality rate was 56.8% (n = 275) and 57.4% (n = 191) in the unvaccinated and two-dose CoronaVac groups, respectively. The 28-day mortality was associated with age, hypertension, the number of comorbidities, type of respiratory support, and APACHE II and sequential organ failure assessment scores (p < 0.05). The odds ratio for the 28-day mortality among those who had received two doses of CoronaVac was 0.591 (95% confidence interval: 0.413-0.848) (p = 0.004).Conclusion:Vaccination with at least two doses of CoronaVac within six months significantly decreased mortality in vaccinated patients than in unvaccinated patients
