Background: Approximately one percent of current live births of the world are conceived via assisted reproductive technologies (ART).
Objective: The purpose of this study was to compare the developmental status of children born through assisted and natural conceptions at the age of five years.
Materials And Methods: In a retrospective cohort study, developmental status of 5 years old children was evaluated via Persian version of 60-month Ages and Stages Questionnaires. Case group consisted of 61 singletons, term babies whom were born through ART in the Research and Clinical Center for Infertility, Yazd, Iran in 2005. Control group consisted of 61 term, first child, singleton and spontaneously conceived born five years old children whom were referred to Shahid Akbari primary health care center in 2010.
Results: 58 girls (47.5%) and 64 boys (52.5%) were evaluated. Frequency of developmental delay in domains of fine motor (47.5% vs. 24.6%, p=0.008) and problem solving (60.6% vs. 34.4%, p=0.004) were more in ART born children. On logistic regression, fine motor development state was independently affected by maternal educational level (OR: 5.3, 95% CI: 1.67-16.30, p=0.004) and developmental status in problem solving domains was independently affected by maternal educational level (OR: 4.88, 95% CI: 1.25-19.07, p=0.02) and birth weight (OR: 7.1, 95% CI: 1.78-29.01, p=0.006) CONCLUSION: Maternal educational level and birth weight are important factors that influenced developmental outcome of ART born children.

Division of Epidemiology and Social Sciences, Institute for Health and Equity, Medical College of Wisconsin, 8701 Watertown Plank Road, Milwaukee, WI, 53226, USA.
Background: During adolescence, a critical developmental phase, cognitive, psychological, and social states interact with the environment to influence behaviors like decision-making and social interactions. Depressive symptoms are more prevalent in adolescents than in other age groups which may affect socio-emotional and behavioral development including academic achievement. Here, we determined the association between depression symptom severity and behavioral impairment among adolescents enrolled in secondary schools of Eastern and Central Uganda.

Immunoglobulin Y (IgY), a unique type of antibody found in birds, is attracting increasing attention for a broad range of biomedical applications. Rational IgY protection, dosage form design, and delivery are highly essential to transform functional IgY antibodies into desired IgY products for therapeutic and prophylactic administration. Although progress has been made in this field, it remains in the early stages, highlighting the fundamental research and development needed in this aspect of IgY technology.

Unlabelled: Our previous study on BRCA breast cancer carriers disclosed a high local recurrence (LR) rate in patients who underwent skin sparing (SSM) or nipple sparing mastectomy (NSM) without postoperative radiation therapy (RT), compared to breast conservation surgery or mastectomy with RT. The current study compares the LR rates in BRCA versus non BRCA carriers after SSM/NSM in relation the receipt of RT.
Methods: The study was approved by the institutional ethics committee.
Does women empowerment impact child well-being? Evidence from India.

This study intends to examine how women's empowerment directly or indirectly impacts their children's well-being. Since prior research primarily focussed on the effects of maternal empowerment on specific domains of child well-being, such as healthcare or education, this study seeks to explore a more comprehensive understanding of child well-being, where child well-being is quantified using four domains, viz., physical well-being, psycho-social well-being, educational well-being and awareness of safety.
