Towards a more holistic understanding of inequalities in childhood::A multi-context approach to parental education and child development

Socioeconomic inequality is one of the most pressing issues of our time. Socioeconomic inequality not only conditions unequal access to opportunities but also creates barriers that hinder children from reaching their full developmental potential. This results in disparities in children’s developmental trajectories. Yet, every child has the right to access equal opportunities to develop skills and competences that enable them to fulfill their potential and to foster overall well-being. Therefore, it is critical to identify and address socioeconomic inequalities in multiple contexts that may lead to differences in developmental trajectories early on. While decades of research have examined associations between socioeconomic status (SES) and a wide range of outcomes, our understanding of the longitudinal contributions of SES at both the household and school levels to child development throughout the elementary school period remains incomplete. The majority of the previous research employed cross-sectional designs, single-level models and/or focused on older children and academic achievement outcomes. Therefore, using a multi-context and a longitudinal approach, the overall aim of the present doctoral thesis was to provide a more holistic understanding of how household- and school-level socioeconomic status (SES) contribute to elementary school children’s development. To do this, the present thesis specifically focused on parental education, which is arguably the most powerful indicator of SES. Moreover, it examined domains of development that extend beyond academic learning, namely, social, emotional, behavioral, and motivational development. This is important because each domain of development relates to the others and acquiring skills in these specific domains promotes positive child development. Within the overall aim, two overarching questions were examined. The first overarching question examined the roles of household- and school-level parental education in the social, emotional, behavioral, and motivational development of children throughout the elementary school period. The second overarching question examined the role of the classroom context in inequalities in child development. Data used in this doctoral thesis came from two longitudinal research projects (‘Happy Children, Happy Adolescents’ and ‘The Dutch Elementary School Sample’) that included repeated measures spanning from kindergarten to end of elementary school. Data were collected from teachers, peers, parents, and children themselves. Overall, the findings of the present doctoral thesis are alarming and show an urgent need to take action to promote equal opportunities for all children regardless of their social backgrounds. To sum up, findings suggested that inequalities in social, emotional, behavioral, and motivational development exist between children growing up in higher- and lower-educated households and children attending higher and lower parental education schools at the beginning, during, and at the end of elementary school. Results showed that schools are not able to fully compensate for disparities in development between children growing up in higher- and lower-educated contexts. While attending higher parental education schools may have some benefits for children of lower-educated parents, they do not always benefit children of lower-educated parents to the same extent as children of higher-educated parents. Furthermore, findings showed that the classroom context may play a buffering (through a classroom based intervention) or exacerbating (through negative classroom norms) role in the problem development of children growing up in higher- and lower-educated households and schools. This doctoral research concludes that it is critical to provide more support to children growing up in lower-educated households and attending lower parental education schools. Importantly, findings indicate that the current efforts are not sufficient to ‘level the playing field’ between children growing up in higher- and lower-educated contexts. Nevertheless, the present doctoral thesis suggests that a multi-context and holistic approach may be necessary to more adequately address the challenges faced by children of lower-educated parents and lower parental education schools

The effect of 8-week thera-band exercises on male swimmers’ 100 m freestyle swimming performance

The aim of this study is to investigate 8 weeks Thera-Band trainings' effects on male swimmers' 100 m freestyle swimming performance.The study group is created by 20 (n = 20) licenced male athletes that had trained at least 3 days in a week and have been active in swimming sport at least 3 years in Gebze Genclerbirligi Swimming Club 20 (n = 20). Athletes were divided into experiment group (n = 10) and control group (n = 10) randomly. Training programme was applied to the study group for 55-60 minutes for 3 days on alternate days and times when the club does not have swimming training. 12 different Thera-Band trainings were applied for 40-45 mins and each set was 15 minutes.Mann-Whitney U test was used to analyze differences between groups and Wilcoxon signed rank test was applied for analyzing the differences of intra-groups. SPSS 21.0 Statistics package software was used for statistical analyzes. The results show that there are no significantly differences between experimental group's and control group's post test results. (p>0.05). Statistically significant differences are found as a result of intra-group comparison of the experimental group's pre-test and post-test results (p<0.05).Depending on the results obtained after reviewing the literature, it can be concluded that Thera-Band training is effective on the performance improvement of swimmers aged 13-15 years

Three adnexal tumors in a single lesion: A case report

Eccrine poroma is a benign tumor originating from the epidermal sweat duct unitis. Malignant transformation may occur in these lesions, and symptoms of bleeding, pain, and pruritus suggest potential malignancy. Common sites of involvement include plantar, palmar, and acral skin, but eccrine poromas may occur in any skin surface area with sweat glands. Hidroacanthoma simplex, eccrine poroma, dermal duct tumor and poroid hidradenoma are four histopathologic types of poroma or poroid neoplasms. Some authors have reported a combination of two or three of these tumors in a single lesion. As far as we know, the overlapping ecrine ductal tumor that covers eccrine poroma(EP), dermal duct tumor(DDT), and eccrine hidradenoma(EH)] has not been reported in the literature. The aim of this report is to present this rare case. ©Copyright 2014 by Gazi University Medical Faculty

Awareness and Prevalence of Traditional and Complementary Medicine in Patients’ Application to Orthopedics and Traumatology Outpatient Clinic

Purpose: The objective of this study was to assess the awareness of complementary and alternative medicine practices and the frequency of their utilization among patients attending an orthopedic outpatient clinic. Materials and Methods: Patients who presented to the orthopedics outpatient clinic of the University Hospital between November 15 and December 30, 2022, were invited to participate in this study. A questionnaire containing 16 questions about eight different traditional and complementary approaches, designed to determine patients' knowledge of and attitudes toward each of these practices, was administered by the responsible physician through face-to-face interviews. The questionnaires were administered to 637 volunteers. The results were recorded, and statistical analysis was applied. Results: The volunteers were % 54.7 male and 45.3.2% female participants. The mean age of the participants was 41.52±16.349. It was determined that gender (p=0.3) and education level (p=0.207) did not affect awareness of traditional treatment. However, it was determined that the settlement area affected the awareness of traditional treatment (p<0.05). Conclusions: The popularity of traditional treatment methods and practices is steadily increasing. The public needs more professional health service providers to reach such treatment approaches and raise awareness. Despite this, it was observed that awareness was low among patients who applied to the orthopedics outpatient clinic. There is a need to educate professional health service providers to facilitate public access to these treatment approaches and to enhance social awareness

Child-Pugh classification dependent alterations in serum leptin levels among cirrhotic patients: a case controlled study

BACKGROUND: As anorexia and hypermetabolism are common in cirrhosis, leptin levels may be increased in this disease. In this study, we investigated the relation between the severity of disease and serum leptin levels in post-hepatitis cirrhosis and the role of body composition, gender and viral aetiology of cirrhosis in this association. METHODS: Thirty-five cases with post-hepatitis cirrhosis and 15 healthy controls were enrolled in this study. Body composition including body mass index, body fat percentage and body fat mass were determined. Serum leptin levels were assayed. RESULTS: Leptin levels were significantly higher among cirrhotic patients independent of sex compared to controls (p = 0.001). Female patients in both groups have had higher leptin levels than males (in cirrhotics p = 0.029, in controls p = 0.02). Cirrhotic patients in each of A, B and C subgroups according to the Child- Pugh classification revealed significantly different levels compared to controls (p = 0.046, p = 0.004, p = 0.0001, respectively). Male cirrhotics in Child-Pugh Class B and C subgroups had significantly higher leptin levels compared to male controls (p = 0.006, p = 0.008). On the other hand, female patients only in Child Pugh class C subgroup have had higher levels of serum leptin compared to controls (p = 0.022). Child-Pugh classification has been found to be the sole discriminator in determination of leptin levels in cirrhotics by linear regression (beta: 0.435 p = 0.015). CONCLUSION: Serum leptin levels increase in advanced liver disease independently of gender, body composition in posthepatitic cirrhosis. The increase is more abundant among patients that belong to C subgroup according to the Child- Pugh classification
