Objective: With the increasing number of cesarean sections worldwide, the need to determine the gestational age for scheduled cesarean sections has increased. The literature needs clear information, especially about cesarean sections four or more times. Our study aims to determine the ideal gestational week for mothers and babies in patients who are not in labor and who will have four or more cesarean sections. Methods: In our retrospective study, the records of 2318 pregnant women were accessed, and those with singleton pregnancies, without medication use during pregnancy, and without any complicated pregnancies, such as newly defined preeclampsia, diabetes, and thyroid disease, and those over 18 years of age were included. All of the cesarean sections were under scheduled conditions (no beginning of labor and no pain/contraction). The exclusion criteria were patients with vaginal dilatation and effacement, a history of uterine rupture, and a diagnosis of placental adhesion spectrum disorder. Maternal and neonatal outcomes were evaluated. Results: Although there was no significant difference in neonatal outcomes according to gestational week, regardless of the number of cesarean sections, transient tachypnea of the newborn increased significantly in scheduled cesareans performed at the 37th week compared with other weeks (p < 0.01). The results can be expected at 39 weeks and above. Conclusion: As a result, patients should not undergo cesarean section before 39 weeks unless they are in labor, and it seems safe to wait until 39 weeks. [ABSTRACT FROM AUTHOR]

Background/aim: There are insufficient tools to assist in the diagnosis and treatment of vestibular migraine. Hence, the aim of this study was to perform the Turkish adaptation of the Vestibular Migraine Patient Assessment Tool and Handicap Inventory (VM-PATHI). Materials and methods: After the language and content validity was completed, a pilot study was conducted. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to test construct validity, and as a result of the validity analyses, Cronbach's alpha internal consistency coefficient and test-retest analyses were conducted for reliability. Results: In the study, in which 289 participants were evaluated, the Kaiser-Meyer-Olkin coefficient was calculated as 0.903. The percentage of variance explained by the EFA was 67.246% and the range of factor load change was 0.433-0.828. The scale structure was tested with CFA and the model was confirmed with adequate goodness of fit index values. The Cronbach's alpha internal consistency coefficient of the scale was 0.931. Conclusion: The VM-PATHI is a valid and reliable tool for the subjective evaluation of vestibular migraine in Türkiye. [ABSTRACT FROM AUTHOR]

In this study, coal properties and environmental characteristics were investigated, and the most suitable coal drying method was determined for four different regions (Armutcuk, Afsin, Can, and Soma) where Türkiye's significant coal reserves are located, using the AHP method (Analytical Hierarchy Process). Installation and operating cost, drying rate, environmental risk, and land area parameters were used as selection criteria in the AHP method. After analyzing the physical and chemical properties of coals from four different regions, changes in moisture content and drying costs were calculated according to various drying methods (rotary, microwave, solar, and air). The results indicated that the solar energy data of the regions were determined to be 1315, 1610, 1400, and 1444 kWh/m²-year for Armutcuk, Afsin, Can, and Soma, respectively. Accordingly, solar energy drying systems are expected to be preferred in regions with high solar energy. However, with the effect of other selection criteria, it was determined that although the Can region receives less solar energy than the Soma region, the microwave drying method should be used for the coal of the Soma region, and the solar energy drying method should be used for the coal of Can region. Microwave and solar energy methods should be preferred for drying the coals of the Armutcuk and Afsin regions, respectively. As in many sectors, multi-criteria decision-making methods are necessary for optimum equipment/method selection in the mining sector. In conclusion, this study showed that the AHP method can be used when appropriate criteria are thoroughly determined. [ABSTRACT FROM AUTHOR]

Objectives: The study is aimed to investigate the association between different corticosteroid treatment regimens and clinical status, complications, mechanical ventilation requirement, and intensive care unit (ICU) mortality in individuals diagnosed with Coronavirus Disease of 2019 (COVID-19). Materials and Methods: This is a descriptive retrospective study. Patients admitted to the ICU for COVID-19 and treated with low- or medium-dose corticosteroid therapy (methylprednisolone at a dose of 0.5-1 mg/kg for 7-10 days) were compared with patients treated with high-dose pulse corticosteroid therapy (methylprednisolone at varying doses of 250 mg, 500 mg or 1000 mg for 3-7 days) in addition to standard therapy because of increased pulmonary infiltrate and elevated inflammatory markers during clinical monitoring. All demographic and clinical data, including age, sex, clinical course, laboratory findings, discharge status, 28-day mortality, intubation status, acute physiological assessment and chronic health evaluation II score, Charlson Comorbidity Index, and sequential organ failure assessment score, were recorded. Results: Corticosteroid treatment was administered to 689 (88.3%) of 780 COVID-19 ICU patients between April 2020 and October 2021. The overall mortality rate was 45.1% (n= 352). When the mortality rates of patients were compared according to the corticosteroid dose, the mortality rate in the low-to-medium-dose group (40%) was significantly lower than that in the high-dose group (76%). In addition, significant deterioration in laboratory and clinical parameters was observed in the high-dose corticosteroid group. Conclusion: High mortality, adverse effects, and complications were significantly increased when high-dose corticosteroids were administered. Corticosteroid therapy should be used cautiously according to the patient's clinical condition, disease stage, comorbidities, and systemic or organ reserves. [ABSTRACT FROM AUTHOR]
