Background: Human milk (HM) has been proven to provide immunological and nutritional advantages to neonates; however, acquired cytomegalovirus (CMV) infection can be associated with raw HM. In Japan, there are no standardized guidelines concerning HM handling. This cross-sectional survey was performed to reveal specific trends in HM handling in neonatal intensive care units (NICUs) in Japan.

Methods: A questionnaire was sent to 255 NICUs participating in the Japanese Neonatologist Association in May 2020. It involved HM handling practices, such as maternal screening, pasteurization, storage, and the workforce.

Results: Of 255 NICUs, 174 (67.8%) responded to the survey. Maternal CMV screening was carried out in 37 units (22.2%), and CMV inactivation in HM was performed in 44 units (26.5%). For CMV inactivation, a freeze-thawing method was employed in about 90% of units. In 70% of units providing CMV inactivation, CMV inactivation was conducted regardless of bodyweight and corrected gestational age of infants until the infants' discharge. Acquired CMV infection in preterm neonates was observed in 43 units (25.7%) in the survey period.

Conclusion: A wide range of HM handling practices are used in Japanese NICUs. A national guideline for handling HM in NICUs should be created to promote the infection control of CMV.

Background: Immumoglobulin A (IgA) vasculitis (IgAV), formerly known as Henoch-Schönlein purpura (HSP), is a self-limiting systemic vasculitis in children. Kidney involvement is associated with a long-term unfavorable outcome and can lead to significant morbidity. This study was conducted to describe the clinical and laboratory characteristics of childhood IgAV with kidney involvement and to identify risk factors associated with IgAV nephritis (IgAVN).

Methods: This was an ambidirectional descriptive study of 77 children with IgAV. All demographic data, clinical features, and laboratory tests were collected from electronic medical records from January 2010 to December 2022. Risk factors for kidney involvement in IgAV were assessed using multivariate logistic regression. Kaplan-Meier survival analysis was used to calculate the time to commencement of kidney involvement.

Results: Twenty-five children (32.4% of the IgAV patients) developed IgAVN. The common findings in IgAV with kidney involvement were microscopic hematuria (100%), nephrotic range proteinuria (44%), and non-nephrotic range proteinuria (40%). Multivariate logistic regression showed that age greater than 10 years (adjusted hazard ratio, AHR 4.66; 95% confidence interval, CI, 1.91-11.41; p = 0.001), obesity (body mass index, BMI, z-score ≥ +2 standard deviations, SDs) (AHR 3.59; 95% CI 1.41-9.17; p = 0.007), and hypertension at onset (AHR 4.78; 95% CI 1.76-12.95; p = 0.002) were associated significantly with kidney involvement. During follow up, most IgAV patients developed nephritis within the first 9 months.

Conclusion: Age greater than 10 years, obesity, and hypertension at presentation were predictive factors for IgAVN. Our study emphasized that IgAV patients with risk factors should be closely monitored for at least 1 year after the onset of the disease.

Background: The recent coronavirus disease 2019 (COVID-19) pandemic and school closures were reported to have negatively impacted the mental health of children and adolescents. This study aimed to examine the change in the number and severity of pediatric suicide attempts before and after the COVID-19 pandemic.

Methods: This study enrolled 54 patients (26 vs. 28 patients before and after the COVID-19 pandemic, respectively) under 19 years of age who were transported to the emergency department as a result of suicide attempts between April 2017 and December 2021. The primary outcome includes the rate of serious suicide attempts (SSAs).

Results: The SSA rates were 19% (5/26) and 43% (12/28) before and after the COVID-19 pandemic, respectively (p = 0.62). The average number of transported suicide attempts per month almost doubled (0.72 vs. 1.33, respectively) and suicide attempts as a percentage of all ambulance transportations of individuals under 19 years old increased significantly from 0.95% (26/2729)to 1.98% (28/1414) (p = 0.006).

Conclusions: The COVID-19 pandemic increased the severity of pediatric suicide attempts but not to a statistically significant degree. Social preventive support and early psychological intervention are therefore needed currently and in the future.

Background: Although furosemide is used during cyclooxygenase (COX) inhibitor therapy for patent ductus arteriosus (PDA), there are concerns regarding increased ductal closure failure and acute renal failure (ARF). This systematic review explores the effects of furosemide during COX inhibitor therapy.

Methods: We searched MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi databases for randomized clinical trials that assessed furosemide during COX inhibitor therapy for PDA in preterm infants. The primary outcome measure was PDA closure failure. Mortality and other complications were also assessed. The risk of bias was assessed using the Cochrane risk-of-bias tool for randomized control trials, and the certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation criteria.

Results: Overall, three trials involving 121 patients were included in the analysis. The overall incidence of PDA closure failure was 28%. Although the result of PDA closure failure, mortality, and ARF were obtained, other outcomes were not described in any of the studies. The risk of bias was high. The risk of PDA closure failure did not increase with furosemide administration. Furosemide was not associated with decreased mortality but was associated with an increased risk of ARF (risk ratio, 4.96 [95% confidence interval: 1.80-13.6]). The certainty of evidence for all outcomes was very low.

Conclusion: Although furosemide is not associated with an increased risk of PDA closure failure or mortality, the risk of ARF increases after furosemide administration during COX inhibitor therapy.
