With recent rapid improvements in neonatal intensive care, the limit of viability has shifted downward to 22-23 weeks' gestation. The younger the gestational age of preterm infants, the higher the risk of survival despite severe neurodevelopmental impairments. For infants born at 22-23 weeks' gestation, the limit of viability, neurodevelopmental outcomes, and survival rates may be determined by the quality of proactive care. Owing to the high risk of severe neurodevelopmental impairment in 22-23 weeks' gestation, proactive care is sometimes withheld according to ethical or legal considerations, and there are significant differences in the provision of proactive care and survival rates across countries or institutions. Additionally, there are differing or even lacking guidelines regarding the care of these infants across countries and institutions. Japan and Sweden are countries with well-established national guidance and proactive care for infants born at 22-23 weeks' gestation, resulting in higher survival rates among them. In Korea, where there is an extreme shortage of neonatologists, maternal transfer before delivery at 22-23 weeks' gestation to high-activity regions with appropriate neonatal intensive care unit resources, such as adequate personnel and facilities similar to the centralized care model seen in Sweden, is crucial for improving the survival rates of infants born at 22-23 weeks' gestation. The survival of these infants largely depends on the quality of proactive care provided. This rate is not static and can be improved through proactive case management based on national guidance and the implementation of enhanced neonatal intensive care practices, including centralization of care.

Background: Despite recent behavioral interventions aimed at reducing the burden of dengue, persistent unfavorable related behaviors in the Indonesian community suggest that vaccination could be effective. However, before this is implemented nationally, public perception and acceptance of the vaccine should be assessed in addition to health providers' points of view.

Purpose: This study aimed to assess the knowledge, attitudes, and practices (KAP) of community members and health providers in Indonesia.

Methods: A cross-sectional survey was conducted in six districts of three Indonesian provinces. Respondents included both community members and health providers living within the territory of the selected primary health care centers. Pretested questionnaires were used to gather information on the sociodemographic characteristics and KAPs regarding dengue vaccines. An independent t-test was performed to compare the mean KAP scores between community members and health providers, while a logistic regression analysis was used to identify the predictors in each domain.

Results: Only 18.5% of health providers possessed high knowledge of the dengue vaccine versus only 12.5% of community members. Approximately one-third of the health providers versus one-fourth of community members displayed a high to moderate score for attitudes about dengue vaccines. Dengue vaccination practices demonstrated a more favorable score for both health providers and community members at 59.1% and 41.1%, respectively. No individual sociodemographic characteristics were associated with KAPs; rather, only education was correlated with better dengue vaccination practices. We also found that good knowledge of dengue was the only factor associated with all domains.

Conclusions: Our findings highlight the urgent need to deliver educational interventions to health providers and community members in Indonesia to improve their awareness of dengue vaccines.

The incidence of childhood obesity is increasing worldwide. National surveys in Malaysia have shown similar trends. This review aimed to increase our understanding of the prevalence and associated factors of childhood overweight, obesity, and excess weight in Malaysia. A systemat-ic review and meta-analysis were conducted of studies reporting the prevalence of overweight and obesity in Malaysian children aged < 18 years. Systematic searches were conducted in Oc-tober 2023 and repeated in March 2024 of the PubMed, Scopus, and Web of Science databases. The grey literature was also included. Study selection, data extraction, and quality assessments were conducted by paired independent researchers. A meta-analysis of prevalence and 95% confidence interval (CI) using a random-effects model and heterogeneity (I2) was calculated. Publication bias was investigated using Egger's test. This review included 33 studies (N=273,710) conducted between 1996 and 2022. Overall, the childhood overweight, obesity and excess weight prevalence was 13.9% (95% confidence interval [CI], 13.0-14.8%), 11.8% (95% CI, 10.9-12.8%), and 24.0% (95% CI, 22.3-25.7%), respectively. Boys had a significant-ly higher proportion of obesity (12.5% [95% CI, 11.1-14.1%] vs. 9.1% [95% CI, 8.1-10.1%]) and excess weight (25.7% [95% CI, 23.5-28.1%] vs. 20.7% [95% CI, 18.8-22.8%]) than girls. Sarawak natives had a higher prevalence of obesity (17.7% [95% CI, 16.0-19.5%]). Annually, the obesity prevalence increased by 0.3% (95% CI, 0.1-0.6%; p=0.006) and excess weight prevalence increased by 0.6% (95% CI, 0.3-1.0%; p=0.002). Heterogeneity was high (I2>90%), and publication bias was possible (p<0.001). Variability was not significantly affected by the critical appraisal score or sample size. In conclusion, the prevalence of childhood overweight, obesity, and excess weight in Malaysia doubled over 26 years. Future studies of the prevalence of childhood excess weight should follow a standardized reference for body mass index by age to ease interstudy comparisons.

Sickle cell disease (SCD) is characterized by chronic hemolytic anemia and intermittent vaso-occlusive crises. To date, four disease-modifying drugs have been approved for the treatment of SCD: hydroxyurea (an S-phase inhibitor), L-glutamine (an amino acid), crizanlizumab (a P-selectin inhibitor), and voxelotor (a hemoglobin S polymerization inhibitor). Preclinical studies suggested that voxelotor effectively treats SCD and sickle cell anemia (SCA). In a phase III trial, voxelotor-treated patients showed significantly elevated hemoglobin levels (>1 g/dL from baseline) compared to placebo-treated patients. The group that received voxelotor also showed a greater decrease in hemolytic markers but a comparable incidence of side effects. Six ongoing clinical trials also sought to ascertain the effectiveness and safety of high-dose voxelotor when administered to children younger than 12 years. Studies assessing their long-term efficacy and safety are needed to fully understand the role of voxelotor in treating SCD/SCA. In this review, we discuss the mechanisms, trials to date, and future treatment directions of voxelotor.

Background: Most studies that estimate the occurrence of childhood stroke use heterogeneous methods and rely on International Classification of Diseases codes, a strategy that may be unreliable.

Purpose: This study aimed to estimate the occurrence of childhood stroke in Indonesia using imaging and clinical data from a private hospital network.

Methods: This cross-sectional study used consecutive retrospective multi-center data samples collected in 2019-2023. The study cohort included children aged >28 days to young adults aged 24 years with confirmed ischemic or hemorrhagic stroke on computed tomography (CT) or magnetic resonance imaging (MRI). The 1-year occurrence was calculated, and the data analysis was performed using SPSS version 26.

Results: Over 5 years, the performance of 8,987 CT and 6,133 MRI scans resulted in the identification of 1,074 stroke cases. The average patient age was 14.8 ± 7 years. Stroke occurrence was highest in 2021 (9.08%) and lowest in 2022 (5.91%). Male patients accounted for 67.9% of cases, with hemorrhagic strokes accounting for 83.4% of the total, primarily resulting from accidents (73.2%) and predominantly occurring in the frontal region (37.1%). A significant majority of cases (66.7%) were reported in Java. Males had a relative risk of 1.93 (95% confidence interval, 1.48-2.52; p < 0.0001) for hemorrhagic stroke versus females.

Conclusion: The incidence of childhood stroke revealed critical epidemiological trends and disparities, emphasizing the need for targeted public health interventions and enhanced stroke prevention strategies in Indonesia.

Background: The increasing global prevalence of obesity poses significant public health problems, as obesity exerts adverse effects on many systems and lung function. However, research on the lung function of preschool children with obesity is limited and inconclusive. In addition, studies specific to obesity indices that influence lung function in young children with obesity are limited.

Purpose: This study aimed to evaluate lung function of obese versus normal-weight preschool children using impulse oscillometry (IOS) and identify obesity indices predictive of altered lung function.

Methods: We enrolled obese children aged 3-7 years as well as age- and sex-matched normal-weight controls. The participants underwent IOS assessments that measured the resistance at 5 Hz (R5) and 20 Hz (R20), the difference in resistance between these frequencies (R5-R20), reactance at 5 Hz (X5), resonance frequency, and reactance area (AX). We compared these parameters between groups and analyzed the correlations between obesity indices and IOS measures within the obese group using multiple linear regression.

Results: The study included 68 participants (n=34 each group). In the obese group, significantly higher values were observed for R5 (adjusted for height, p = 0.02; % predicted, p = 0.01; z-score, p < 0.001), R5-R20 (absolute value, p = 0.002; adjusted for height, p = 0.001), and AX (z-score, p = 0.01). AX adjusted for height showed a greater trend (p = 0.07). The waist-to-height ratio was the most robust independent predictor of total and peripheral airway resistance, with increases in R5 (b = 1.65, p = 0.02) and R5-R20 (b = 1.39, p = 0.03) and a near-significant correlation with AX (b = 12.12, p = 0.06).

Conclusion: Preschool children with obesity exhibit impaired lung function, characterized by elevated total and peripheral airway resistance. Waist-to-height ratio was the strongest predictor of these changes.

Background: Individuals with 21-hydroxylase deficiency (21OHD) require lifelong glucocorticoid (GC) therapy, which increases their risk of fragility fractures. However, fractures in GC-treated individuals can occur at normal bone mineral density (BMD) levels, suggesting an alteration in the bone microarchitecture.

Purpose: To evaluate trabecular bone microarchitecture and its changes in adolescents with 21OHD.

Methods: We enrolled 38 adolescents with 21OHD for whom complete clinical data and baseline and follow-up lumbar spine bone mineral density (LSBMD) measurements were available. The mean duration was 1.5 ± 0.6 years. Trabecular bone score (TBS), an indirect measurement of bone microarchitecture, was analyzed using iNsight™ software version 3.0. Impaired BMD and TBS were defined at Z-scores ≤ -1.5.

Results: At baseline, participants (55% female; 68% salt-wasting type; mean age, 15.2 ± 3.8 years; bone age, 17.5 ± 2.8 years; mean GC dose, 18.5 ± 6.5 mg/m2/day) had the prevalence of impaired BMD and TBS of 5% and 18%, respectively. During follow-up, adolescents with 21OHD receiving prednisolone showed a lower annual percentage change in TBS than those who received hydrocortisone (p = 0.028). A stepwise regression analysis showed that body mass index percentile (p < 0.001) and testosterone concentration (p = 0.002) were independent positive predictors of the baseline TBS Z-score, whereas prednisolone use was the only negative predictor of the annual percentage change in TBS (p = 0.002).

Conclusion: Adolescents with 21OHD have a high prevalence of impaired bone microarchitecture. Furthermore, prednisolone therapy is associated with impaired bone microarchitecture development, suggesting that hydrocortisone may better preserve bone microarchitecture and should be considered the first-line treatment for this population.
