Young children and preschoolers are now growing up in settings filled with a variety of technological devices. Despite the recommendation that parents should limit screen time, many preschoolers are exposed to screens at very early ages and for a long time. This study aimed to investigate the associations between parenting styles and the excessive screen time of preschool-aged children. This cross-sectional descriptive study included preschool children with low screen exposure (4 hours; n=74). A self-completion-structured survey form and Parent Attitude Scale were filled by the mothers. More than half (52.0%) of them were male children. Increased number of children, increased household sizes, mothers being unemployed, birth order ≥2, and home-based care were found to be statistically significantly higher in the excessive screen exposure group than in the low screen exposure group. Mothers and fathers in the excessive screen exposure group had lower educational levels compared with their counterparts in the low screen exposure group (p<0.001). Multivariate logistic regression analyses showed that mothers’ high authoritative (democratic) scores were associated with low screen exposure(adjusted odds ratio (AOR): 0.3; 95% confidence interval (CI): 0.1–0.9). High overprotective and permissive parenting subscale scores were related to excessive screen exposure after adjusting potential confounders (AOR: 2.8, 95% CI: 1.1–6.7; AOR: 4.5, 95% CI: 1.8–11.6). Excessive screening time may indicate a problematic parent-child relationship. Establishing a positive parent-child relationship can be an effective way of managing screen time in preschool children.

Background and Objectives. The comparison of Positron emission tomography- computed tomography (PETCT) and bone marrow biopsy (BMB) modalities in detecting bone marrow disease is an up to date research topic. In this study, we aimed to compare the results of PET-CT and BMB procedures in detecting bone marrow involvement in pediatric malignancies. Method. At the time of diagnosis, PET-CT imaging and BMB performed patients` data were evaluated, retrospectively. Malign diagnoses were Hodgkin's lymphoma in 23 (30.7%), non-Hodgkin's lymphoma in 20 (26.7%), neuroblastoma in 11 (14.7%), Ewing sarcoma in 10 (13.7%), Langerhans cell histiocytosis in 6 (8%), and rhabdomyosarcoma in 5 (6.6%) patients. Results. Bone marrow involvement was detected in 39 (52%) of 75 patients. Bone marrow involvement was identified by both PET-CT and BMB in 18 (46.1%) patients, by only PET-CT in 12 (30.7%) patients, by only BMB in 9 (23%) patients. The sensitivity of PET-CT was 66%, specificity was 75%, positive predictive value was 60%, and negative predictive value was 80%. Sensitivity, spesificity, positive and negative predictive values of PETCT were different in before mentioned malignancy groups. Conclusion. PET-CT may not have high sensitivity and specificity to identify bone marrow involvement for each type of cancer. The approach of using bone marrow biopsy and PET-CT as complementary modalities seems reliable.

Breastfeeding offers critical benefits in disasters but faces significant barriers. In this study, we aimed to determine the association between experiencing the 2023 Türkiye earthquake and breastfeeding problems. This cross-sectional descriptive study was conducted in pediatric clinics in eight different provinces of Türkiye, three earthquake-affected provinces and five earthquake-unaffected provinces, between April and July 2023. Breastfeeding mothers and their 0–23 month infants were included in the study. A structured questionnaire was applied to mothers face-to-face. Multivariate logistic regression analysis was performed to determine independent parameters associated with breastfeeding problems. A total of 761 mother-child pairs participated in the study. Among these mothers, 49% (n = 373) were living in the earthquake-affected region, and 51% (n = 388) were not. Breastfeeding problems were more common in the earthquake-affected mother-child pairs (48.8%) compared to unaffected pairs (28.6%). Perceived insufficient milk supply was the most common breastfeeding problem, reported by 33.0% in earthquake-affected regions and 11.1% in unaffected region. Breastfeeding problems were 2.01 times more common in mothers from earthquake-affected region (95% CI: 1.45, 2.77) and 1.66 times more common in those who bottle-fed their infants (95% CI: 1.45, 2.37). Perceived insufficient milk supply was 4.12 times more prevalent in earthquake-affected regions (95% CI: 2.73, 6.22) and 1.78 times higher in bottle-feeding mothers (95% CI: 1.23, 2.57). The likelihood of perceived insufficient milk supply was lower in mothers receiving mental health support (AOR: 0.53, 95% CI: 0.33, 0.84) and nutritional support (AOR: 0.49, 95% CI: 0.27, 0.89). Perceived insufficient milk supply is the most common breastfeeding challenge reported by mothers affected by earthquakes, occurring more frequently than among mothers who were not affected. This issue is associated with increased bottle feeding, limited mental health support, and inadequate nutritional support. Addressing this issue through adherence to the International Code of Marketing of Breast-milk Substitutes, controlling donation and distribution of commercial milk formula to discourage bottle feeding, alongside ensuring nutritional and mental health support for mothers, could significantly mitigate breastfeeding difficulties during disasters.
