School-based prevention of teacher and parental violence against children: Study protocol of a cluster-randomized controlled trial in Tanzania.

Background: Violence against children at home and at school is particularly prevalent in Africa and is associated with adverse and persistent health effects on children. The violence prevention intervention Interaction Competencies with Children - for Teachers (ICC-T) is an effective tool to reduce violence against children by fostering teachers' non-violent communication and interaction skills. To enhance these effects, in the present study, ICC-T will be extended to parents (ICC-P) aiming to increase children's experience of consistent behavior and application of non-violent discipline strategies between teachers and parents.

Serum Ferritin Levels in Severe Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) has been associated with various acute and chronic inflammatory diseases, as has serum ferritin, an intracellular iron storage protein. Little is known about the relationship between severity of OSA and serum ferritin levels in otherwise healthy subjects. In this study, all polysomnographic recordings, serum levels of ferritin, C-reactive protein (CRP), and hemoglobin, as well as patient files from 90 consecutive, otherwise healthy individuals with suspected OSA who presented to a tertiary sleep medical center were retrospectively analyzed.

Obstructive Sleep Apnea Disrupts Glycemic Control in Obese Individuals.

The link between obstructive sleep apnea (OSA) and obesity, and their common comorbidities such as diabetes mellitus (DM) or cardiovascular diseases, is not fully understood. The aim of this study was to investigate the possible association of OSA severity in obese individuals with polysomnography-based sleep parameters, as well as C-reactive protein (CRP) and glycated hemoglobin (HbA1c) serum levels. Polysomnographic recordings and blood samples were retrospectively compared between a group of 23 adult obese individuals with mild OSA (apnea-hypopnea index (AHI) = 7.

COVID-19 crisis in Cambodia: A dataset containing linked survey and administrative data of ninth-graders in rural areas.

Between 2019 and 2021, we collected detailed administrative data of grade 9 students from 54 lower-secondary schools in rural Cambodia. We also collected phone-survey data from these students in July and August 2020, to understand the implications of the nation-wide lockdown, that was implemented to curb the spread of COVID-19 in March 2020. The administrative data contain information on students' grades, school characteristics and teacher characteristics from the school year 2019-2020, as well as information about the students' enrollment in high school after the end of the school year (January 2021).
