There are about 15072 clinical studies being (or have been) conducted in Turkey. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
In a present study vaginal examination of the fetal head station is compared with transperineal ultrasonography evaluation of fetal head station and the ability of ultrasonography evaluation in predicting the time and mode of delivery will be investigated.
Obesity has become an increasingly common health problem today. In this context, although many anatomical, physiological and metabolic problems arising from obesity in morbid obese patients are tried to be solved in daily practice, it has been proven that eliminating obesity is sufficient in the treatment of many diseases. When we look at the literature, it is known that morbid obesity causes deformation and excessive wear in most body joints. When morbid obesity disappears, it has been shown that the previously existing neck, waist, back and knee pains regress. The aim of this study is to reveal the Cobb angle change in morbidly obese patients who achieved rapid weight loss after obesity surgery; To investigate the effect of weight loss on vertebral anatomy.
Background and Aim: Pulmonary aspiration of gastric content in the perioperative period is rare, but it is an important cause of morbidity and mortality that anesthetists never want to encounter. Due to reasons such as emergency surgical procedures, communication problems with pediatric patients or their parents, impaired cognitive function, obesity, diabetes mellitus, chronic liver and kidney diseases, it is observed that there is sometimes inconsistency between the periods defined in the preoperative fasting guidelines in pediatric patients and the state of gastric content and volume encountered in clinical practice. There is a lack of data on children on this issue. In this study, primary we aimed to evaluate the incidence of empty and full stomach in pediatric patients who underwent elective and emergency surgery in our routine anesthesia practice. Also we want to determine the relationship between fasting time and qualitative assessment of gastric content. Secondary this study sought to examine whether correlation between gastric ultrasound finding and fasting time, and also to determine relationship with the current comorbidities. Design: This is a prospective, single blinded, observational study. The minimum sample size required to determine the prevalence of full stomach, 0.05, within the limits of ± 0.025 with 0.95 confidence, was calculated as 292. When calculating with the proposed equation of n = 100 + 50i to determine the factors affecting by logistic regression (here i is the number of variables in the model), the minimum number of samples required for logistic regression analysis was calculated as 300 in case of 4 independent variables in the model. n=100+50*4= 300 Methods: Pediatric patients younger than 18 yr old who are to undergo elective and emergency surgery under general anaesthesia at our hospital are enrolled in this prospective observational study between April and December 2021. Preoperative ultrasound examination of the gastric antrum are performed by one anesthesiologist who has been instructed and supervised by an experienced pediatric radiologist and who is blind to the patient's history. Ultrasonographic measurement of the gastric antral cross-sectional area (CSA) are performed in supine position and right lateral decubitus position (RLD). The gastric antrum is imaged in a sagittal plane, between the left lobe of the liver and the pancreas, at the level of the aorta, as previously described [1]. This examination allowed qualitative assessment of gastric contents according to the three-point grading scale previously described by Perlas and colleagues[2]. Grade 0 was defined by the absence of appearance of any content in a flat antrum in both the supine and the RLD positions. Grade 1 was defined by the appearance of any gastric content in the RLD position only, and Grade 2 was defined by the appearance of any content in both the RLD and the supine positions. The antral cross-sectional area is also calculated in both position, by measuring the longitudinal diameter (D1) and the anteroposterior diameter (D2) of the antrum, from serosa to serosa using this formula [3] Antral area= (π x D1 X D2) / 4. Patients' characteristic data ( age, gender, weight, height, BMI and ASA physical status classification), fasting duration, type of elective and emergency surgery, chronic disease and complications (regurgitation, pulmonary aspiration, etc.) that may develop during the peroperative period are recorded.
The primary purpose of this study is to assess the long-term safety and tolerability of esketamine nasal spray in combination with a selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor (SSRI/SNRI) in participants who have completed 32 weeks of esketamine nasal spray treatment in Study 54135419TRD3013 (NCT04338321).
The clinical performance of a bioactive composite and a posterior resin composite in class II restorations will be evaluated and compared. After recruiting participants with at least 2 approximal caries lesions, all restorations will be placed by a single clinician. All caries lesions will be removed before restoring. Cavities will be divided into two groups: a bioactive composite [Cention N, Ivoclar Vivadent, Schaan, Liechtenstein (CN)] and a posterior resin composite [G-ænial Posterior (GC, Tokyo, Japan) (GP)] All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using FDI criteria after a week (baseline) 6, 12, 24, 36 and 48 months. Descriptive statistics will be performed using chi-square tests.
This is a phase 3, multicenter, randomized, double-blind, placebo-controlled trial designed to compare the efficacy and safety of the humanized monoclonal anti CD19 antibody tafasitamab plus lenalidomide in addition to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) versus R-CHOP in previously untreated, high-intermediate and high-risk patients with newly-diagnosed DLBCL
The purpose of the study is to evaluate the safety and efficacy of talazoparib in combination with enzalutamide compared with placebo in combination with enzalutamide in participants with DDR-deficient mCSPC.
To evaluate the clinical performance of the restorations by applying the universal adhesive in different modes under the influence of different surface treatments, with Erbium Chromium:Yttrium-Scandium-Gallium-Garnet (Er,Cr:YSGG) laser and acid etching in non-carious cervical lesions.
