Maternal-fetal outcome associated with adolescent pregnancy in a tertiary referral center: a cross-sectional study

Objectives: This study was conducted to compare pregnancy outcomes of early-middle adolescent, late adolescent and adult women. Material and methods: The study focused on early-middle adolescent (n = 145), late adolescent (n = 1655) and adult (n = 1585) women who gave birth during 2014 through 2017, utilizing data obtained from the Zeynep Kamil Women and Children’s Health Training and Research Hospital. Pregnancy outcomes were determined according to the rates of preg¬nancy complications, including method of delivery, birth weight, as well as the rate of newborn intensive care admissions. Results: Comparisons between the studied groups for various pregnancy complications showed highest rates of pre¬term deliveries (PD), preterm premature rupture of membranes (PPROM) and neonatal intensive care unit admission in early-middle adolescent group, whereas the highest cesarean section rates were observed in the adult group (p < 0.001). Conclusions: Analysis of the data revealed that adolescent pregnancy, especially the early-middle adolescent pregnancies, is associated with increased risks of adverse pregnancy outcomes

The comparison of bone mineral density in primary hyperparathyroidim, vitamin D induced secondary hyperparathyroidism, and patients with both condition: a single center experience

Background: To compare bone mineral densities via dual energy X-ray absorptiometry method (DXA) between various hyperparathyroidism (HPT) types such as primary, vitamin D induced secondary, and both conditions.Methods: Participants who were aged between 18-45 years and had elevated parathyroid hormone levels were included. After initial evaluations, patients were divided into 3 groups according to diagnoses: primary HPT (pHPT), vitamin D induced secondary HPT (sHPT), and combined (primary+secondary) one. In addition to the bone mineral density (BMD), demographic and laboratory datas were recorded.Results: Of 166 patients, 147 of the patients were female, 19 were male, and average age was 38.10±7.24 years. Significant difference was found in terms of age (p=0.03) between pHPT and sHPT. Blood calcium, PTH, 25-OH vitamin D, and daily urine calcium excretion levels were significantly higher and phosphorus levels were lower in the pHPT group compared to the sHPT and combined disease group. Both T and Z scores of the pHPT group were significantly lower than the sHPT group especially in the lumbar region. However, no significant difference was noted between pHPT and combined disease group with respect to T and Z scores in all regions.Conclusions: The results of this study indicate that pHPT has a significantly worse impact on skeletal mineral density particularly in the lumbar region than sHPT. The addition of vitamin D deficiency to the clinical picture seems to have no significant influence on BMD in pHPT. To confirm and clarify these findings, prospective studies with larger number of participants are needed

What does previous research tell us about the effects of peer tutoring on metacognition in primary and secondary schools?

This systematic evidence synthesis examined the reported research on the effect of peer tutoring on metacognition in primary and secondary school students. A comprehensive search of multiple databases, including ERIC, Education source, British Education Index, ProQuest, Scopus, and Psych Info was conducted. The evidence synthesis included experimental studies on peer tutoring and metacognition from 1st January 1990 to 11th November 2022. The criteria for inclusion were the use of randomized controlled or quasi-experimental designs with a control/comparison group, implementation of the intervention in formal school educational settings with students aged 5–18 years old, and the use of peer tutoring as an intervention and metacognition as a measured outcome. Seven-hundred and eighteen studies were identified including 86 duplicate records. Six-hundred and thirty-two records were screened for inclusion and 630 were rejected as not meeting the selection criteria, leaving two studies for inclusion. Studies were assessed for quality using the Briggs appraisal tool for quasi-experimental/experimental studies. Despite the abundance of literature on the effects of peer tutoring on academic and social outcomes, this review highlighted the severe lack of published peer-reviewed research on the impact of peer tutoring on metacognition in school students

An Unusual Cause of Precordial Chest Pain

Extraskeletal chondrosarcoma in anterior mediastinum is very rare. A 45-year-old male patient was admitted to the hospital with precordial chest pain. A large and well-shaped mass in the anterior mediastinum was seen radiologically, and there was a clearly compression of the heart by the mass. The lesion was totally resected, and extraskeletal mediastinal chondrosarcoma was histopathologically diagnosed. We aimed to present and discuss the radiologic, clinic, and histopathologic features of unusual presentation of extraskeletal chondrosarcoma in a case

Endobronchial tuberculosis: histopathological subsets and microbiological results

Abstract Background Endobronchial tuberculosis (EBTB) is defined as a tuberculous infection of the tracheobronchial tree with microbial and histopathological evidence, with or without parenchymal involvement. Bronchoscopic appearances of EBTB have been divided into seven subtypes: actively caseating, edematous-hyperemic, fibrostenotic, tumorous, granular, ulcerative, and nonspecific bronchitic. However, information for establishing a definite microbiological diagnosis in each of these categories is lacking. We aimed to present bronchoscopic appearances and percentages for the EBTB subtypes and to compare bronchoscopic appearances with microbiological positivity in bronchial lavage fluid. Methods From 2003 to 2009, 23 biopsy-proven EBTB patients were enrolled in the study. Diagnosis of EBTB was histopathologically confirmed in all patients. Results The commonest subtype was the edematous-hyperemic type (34.7%); other subtypes in order of occurrence were: tumorous (21.7%), granular (17.3%), actively caseating (17.3%), fibrostenotic (4.3%), and nonspecific bronchitic (4.3%). Although all patients were sputum-smear-negative for acid-fast bacilli (AFB), 26% of patients were smear-positive for AFB in the bronchial lavage fluid. The bronchial lavage fluid grew Mycobacterium tuberculosis in 39.1% of all patients. The bronchial lavage smear positivity for AFB in the bronchial lavage fluid was 75%, 25%, 20%, 12.5%, 0%, and 0% for the granular, actively caseating, tumorous, edematous-hyperemic, fibrostenotic, and nonspecific bronchitic subtypes of EBTB, respectively. Culture positivity for Mycobacterium tuberculosis in bronchial lavage fluid was 75%, 50%, 40%, 25%, 0%, and 0%, respectively. Conclusion The commonest subtype of EBTB was the edematous-hyperemic subtype. The granular type had the highest smear positivity and culture positivity for Mycobacterium tuberculosis in bronchial lavage fluid. Bronchoscopy should be performed in all patients suspected to have EBTB.</p

Nasopharyngeal carcinoma radiotherapy with hybrid technique

The aim of the study was to investigate the effect of the Hybrid technique which was created by combining of intensity modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) for the treatment of nasopharyngeal cancer (NPC) patients. 7 to 9 field IMRT, triple arc VMAT, and Hybrid plans were generated for 10 advanced stage NPC patients. The homogeneity index (HI) and the conformity index (CI) of planning target volumes (PTVs) were calculated for each technique to evaluate the plan quality. The techniques were compared in terms of plan quality, sparing of organs at risk (OARs), monitor units (MUs), and delivery time. Hybrid technique significantly improved the target dose homogeneity and the conformity for PTV70 and PTV60 compared to IMRT and VMAT. Hybrid plans significantly reduced the maximum dose of the brainstem sparing compared to the VMAT plans and also improved the sparing of spinal cord compared to IMRT and VMAT. The MUs and the delivery time of Hybrid plans were found to be between values for IMRT and VMAT plans. Hybrid technique can be useful when IMRT and VMAT techniques are not adequate alone in the treatment of NPC patients. (C) 2018 American Association of Medical Dosimetrists. Published by Elsevier Inc.

Effect of Rosiglitazone and Insulin Combination Therapy on Inflammation Parameters and Adipocytokine Levels in Patients with Type 1 DM

Aim. To investigate the efficacy of combined therapy of insulin and rosiglitazone on metabolic and inflammatory parameters, insulin sensitivity, and adipocytokine levels in patients with type 1 diabetes mellitus (type 1 DM). Material and Methods. A total of 61 adults with type 1 DM were randomly and prospectively assigned in open-label fashion to take insulin and rosiglitazone 4 mg/day (n=30) or insulin alone (n=31) for a period of 18 weeks while undergoing insulin therapy without acute metabolic complications. Results. Combination therapy did not significantly improve metabolic and inflammatory parameters, insulin sensitivity, and adiponectin levels. While leptin and resistin levels decreased in both groups (group 1: resistin 6.96 ± 3.06 to 4.99 ± 2.64, P=0.006; leptin 25.8 ± 17.6 to 20.1 ± 12.55, P=0.006; group 2: resistin 7.16 ± 2.30 to 5.57±2.48, P=0.031; leptin 16.72 ± 16.1 to 14.0 ± 13.4, P=0.007) Hgb and fibrinogen levels decreased only in group 1 (Hgb 13.72 ± 1.98 to 13.16 ± 1.98, P=0.015, and fibrinogen 4.00 ± 1.08 to 3.46 ± 0.90, P=0.002). Patients in both groups showed weight gain and the incidence of hypoglycemia was not lower. Discussion. The diverse favorable effects of TZDs were not fully experienced in patients with type 1 DM. These results are suggesting that insulin sensitizing and anti-inflammatory characteristics of TZDs were likely to be more pronounced in patients who were not totally devoid of endogenous insulin secretion
