This aimed to investigate associations between the vitamin D status and handgrip strength in children and adolescents considering weight status. Participants aged 7 to < 16 years from the European IDEFICS/I.Family cohort were included. Serum 25-hydroxyvitamin D [25(OH)D] and handgrip strength were measured in 2013/2014. In multivariable logistic regression models, we investigated the association of vitamin D status with handgrip strength adjusted for demographic variables, BMI z-score, sports club membership, screen time and UV intensity. Vitamin D-sufficient children had higher odds for a high handgrip strength (OR = 1.92, 95%-CI: 1.12, 3.30), but this association was limited to children with thinness/normal weight (OR = 2.60, 95%-CI: 1.41-4.81). Children with overweight (OR = 2.64, 95%-CI: 2.00, 3.49) and obesity (OR = 4.53, 95%-CI: 2.93, 7.02) were more likely to have a high handgrip strength than thin/normal weight children.

Conclusions: The positive association of vitamin D with muscle strength in our study is limited to children with low and normal BMI. In children with overweight or obesity, the higher muscle strength seems to superimpose the association with vitamin D. Overall, our results indicate the importance of sufficient levels of vitamin D and offers physical activity perspectives for children with overweight and obesity.

What is known: • Studies have shown a positive association between vitamin D status and handgrip strength in older adults while studies in children and adolescents are scarce. • Conflicting results were found on whether overweight and obesity are associated with reduced or increased handgrip strength compared to normal weight.

What is new: • The results of this large pan-European study in children and adolescents indicate that a sufficient vitamin D status is associated with better handgrip strength, particularly in participants with thinness/normal weight. • Children with overweight and obesity have a higher handgrip strength as compared to children with thinness/normal weight which seems to superimpose the positive association between vitamin D status and handgrip strength in this group.

Pediatric drowning incidents, both fatal and non-fatal, represent a significant challenge in emergency medicine, particularly for children under 14 years of age. Drowning is a leading cause of unintentional injury-related deaths, with children aged one to four years being especially vulnerable. Accurate and timely assessment, particularly through chest imaging, such as chest radiography (CXR) and lung point-of-care ultrasound (LUS), is crucial for evaluating pulmonary complications and guiding treatment decisions. This retrospective study analyzed 64 pediatric drowning cases in Istituto Giannina Gaslini, Italy, from 2012 to 2023. For all patients, demographic data, vital parameters, blood tests upon PED admission and at 24 h, need for intensive care unit admission, length of stay, therapies administered, ventilatory support in the PED and in the hospital ward, and mortality were recorded. The patients were subsequently divided into two groups based on the chest X-ray result. The results indicated that pathological CXR findings upon admission were associated with a higher likelihood of hospital admission, prolonged hospital stay, and more severe clinical outcomes, including the need for oxygen supplementation and antibiotic therapy. Patients with abnormal CXR findings also exhibited lower oxygen saturation, Glasgow Coma Scale scores, and body temperature upon admission, reflecting a more significant physiological compromise, and higher RCP values at 24 h.

Conclusion: Although the majority of non-fatal drowning patients recovered without lasting neurological deficits, the findings suggest that CXR plays a critical role in early management, assisting in the identification of those at greater risk for complications.

What is known: • Fatal and non-fatal pediatric drowning incidents may represent a critical issue in pediatric emergency medicine, requiring prompt assessment and accurate management upon admission, even if standardized protocols are lacking.

What is new: • Chest imaging in the initial assessment of pediatric drowning cases may serve as a fundamental tool to support early clinical decision-making, particularly when integrated with other key parameters such as neurological status, vital signs, and blood exams.

The purpose of this study is to evaluate the efficacy of a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) in adolescents with irritable bowel syndrome (IBS) and functional abdominal pain-not otherwise specified (FAP-NOS) in a non-guided setting, resembling clinical practice. This prospective multicenter cohort study conducted in 13 centers included patients aged 12-18 years diagnosed with IBS or FAP-NOS. Patients received educational material on FODMAPs, including extensive lists of high and low FODMAP foods and additional online information. They were instructed to replace high FODMAP foods with low FODMAP alternatives for the duration of 4 weeks. No dietician was consulted. The primary end point was the proportion of patients with treatment success (≥ 30% reduction of abdominal pain intensity) at 4 weeks. The key secondary outcome was adequate relief of IBS/FAP-NOS symptoms. Of the 325 included patients, 81 patients (24.9%) achieved treatment success (≥ 30% reduction of abdominal pain intensity) after 4 weeks, with higher rates in patients with IBS (29.3%) than FAP-NOS (16.8%, OR 2.16 (1.04-4.48)). Adequate relief was reported in 51 patients (15.7%). There was a significant decrease in abdominal pain intensity (2.2 (1.1) vs. 2.5 (1.0), P < 0.001), daily bloating (2.4 (2.1) vs. 2.8 (2.3), P < 0.001), and flatulence (2.4 (2.1) vs. 2.8 (2.3), P = 0.001). Adverse events were mild and infrequent.

Conclusion: The low FODMAP diet in a non-guided setting, mimicking clinical practice, yielded treatment success in almost 30% adolescents with IBS and 17% in FAP-NOS, suggesting it may not be the first treatment option for these patients.

What is known: • Irritable bowel syndrome (IBS) and functional abdominal pain-not otherwise specified (FAP-NOS) are common disorders in children which negatively impact quality of life. • While a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) has demonstrated effectiveness in adult IBS, its efficacy in pediatric IBS and FAP-NOS remains uncertain. • Clinical application of the low FODMAP diet often occurs without dietician consultation, contrary to controlled trial settings.

What is new: • The low FODMAP diet, without dietician guidance, resulted in treatment success in almost 30% of adolescents with IBS and only 17% with FAP-NOS. • With only 15.7% of participants achieving adequate relief of IBS/FAP-NOS symptoms, the non-guided low FODMAP diet may not be the first treatment option for pediatric IBS and FAP-NOS.

We hypothesized that certainty of the available evidence is relatively low in neonatology. Thus, we designed a meta-epidemiological review to examine what is the certainty of evidence in the latest Cochrane neonatal reviews and investigate if the number of trials and enrolled patients is associated with the certainty of evidence. We searched Cochrane neonatal reviews published between January 2022 and May 2024. We included all reviews on interventions concerning neonates that had at least one meta-analysis performed with GRADE-rated evidence certainty. From those reviews, we extracted the presented certainty of evidence and analyzed its association with the number of trials and participants by ANOVA. We screened 55 Cochrane reviews and included 49 of them. In these 49 reviews, there were 443 reported outcomes with graded certainty of evidence. The certainty was reported to be high in 8 (1.8%), moderate in 89 (20.2%), low in 195 (44.0%), and very low in 151 (34%) of the outcomes. Reviews reporting outcomes with higher certainty of evidence had significantly more trials and patients (approximately 3 and 1.5 times more, respectively) than those with only low certainty of evidence.

Conclusion: In the past 2 years, Cochrane neonatal reviews have generally had low or very low certainty of evidence for most outcomes. Only 2% of the reviewed outcomes had high certainty. The number of included patients and trials significantly affected the certainty. These findings highlight the continuous need for better quality and larger trials.

What is known: • Neonatology is among the largest specialities and the evidence certainties of interventions have been varying. • Neonatal patients and studies need to consider the uniqueness of the patients and the acute situations in the study designs.

What is new: • The included 49 reviews consisted of 443 outcomes and of these only 1.8% were classified as high certainty of evidence. • Higher evidence certainties were associated with higher number of included trials and participants.

To understand whether parental smoking influences adeno/tonsillectomy rates in their offspring. A population-based case-control study using data from Clalit Health Services. Israeli children aged 0-18 years who underwent adeno/tonsillectomy between 2003 and 2022 were 1:3 matched with same-age, sex, and ethnicity controls. Parental smoking habits were linked to their children's files. Conditional logistic regression models estimated odds ratios (ORs) for adeno/tonsillectomy associated with parental smoking, adjusting for socioeconomic status. We identified 11,184 children who underwent surgery and 33,552 controls (mean age ± SD 4.10 ± 2.50 years). The likelihood of undergoing adeno/tonsillectomy was significantly higher for children with either one smoking parent (OR 1.14; 95%CI 1.09-1.19) or both (OR 1.53; 95%CI 1.39-1.68) compared to children of non-smokers. The association was more evident for tonsillectomy alone, with an OR of 3.20 (95%CI 2.06-4.97) when both parents were smokers. These associations remained consistent even after adjusting for socioeconomic status. Parental smoking rates were higher in the surgical group across all categories. Maternal smoking prevalence was 10% versus 7.5%, and paternal smoking prevalence was 36% versus 32%, in the surgical group vs. the control group, accordingly. The proportion of children with only one smoking parent was 34% compared to 31%, and for cases with both parents smoking, the rate was 6.3% versus 4.3%.

Conclusion: Parental smoking is associated with higher rates of pediatric adenoidectomy, tonsillectomy, and adenotonsillectomy, especially if both parents smoke. Counseling parents on the negative effects of smoking on their children is crucial in reducing the incidence of these surgeries.

What is known: • Parental smoking can cause multiple pediatirc diseases.

What is new: • Parental smoking is associated with higher rate of adenotonsillar surgery.

The Surprise Question "Would you be surprised if the patient died in the next 12 months?" lacks pediatric research, particularly in neonatal patients. Our study aims to analyze the Surprise Question's predictive ability in neonates and explore pediatricians' views on palliative care patient identification. A prospective cross-sectional study was conducted from February 2021 to June 2023, including all newborns admitted to the Neonatal Intensive Care Unit of a pediatric tertiary hospital and its pediatricians. Patients with less than a year since admission were excluded from final analyses. Recorded variables included patient demographics and condition, pediatricians' profile and opinions regarding the Surprise Question, and palliative care patient identification. The Surprise Question was formulated to one or more pediatricians per neonate at admission, 7 days of life, and 28 days of life, with patient status recorded after 12 months to elaborate a confusion matrix of prognostic test results. A total of 51 pediatricians participated. Most felt they had limited criteria for identifying palliative care patients (55%), believed the Surprise Question could be useful (77%), and predicted death (75%). The Surprise Question was answered at least in one out of the three moments for 262 neonates (61% male and at least 36% preterm), with sufficient sample at each moment to study its predictive ability. High negative predictive values were consistent, with higher positive predictive value at 7 days (26%).

Conclusions: The Surprise Question is a promising tool for predicting neonatal outcome and could guide professionals in initiating palliative care discussions. The 7-day mark appears more suitable for this application.

What is known: • Previous research has established the Surprise Question as a valuable tool for predicting death in adults. However, limited research exists on its use in pediatric patients and its role remains unexplored in the neonatal period.

What is new: • The study evaluates the Surprise Question as a tool for predicting death within the first year of life when applied in the neonatal period. It offers insights into its predictive ability and most suitable time for its application. This study sheds light on its applicability in neonatal care, offering a valuable tool for early identification and referral to palliative care.

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental condition in children, characterized by inattention, hyperactivity, and impulsivity. Recent studies have investigated the potential role of physical exercise as a complementary intervention to traditional ADHD treatments. This study aimed to compare the effects of moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) on ADHD symptoms and behavioral inhibition in children diagnosed with ADHD. In a randomized controlled trial, 60 male participants aged 7-10 years were allocated into three groups: control, MICT, and HIIT. The intervention lasted 12 weeks, with the MICT group performing 20 min of running at 70-75% of their individual VO2 max and the HIIT group performing alternating intervals of running at 100% and 50% of their VO2 max for 1 min each. The control group received no exercise intervention. Cognitive and symptomatic assessments were conducted using the Children's Symptom Questionnaire (CIS-4) and go/no-go tasks before and 48 h post-intervention. Both MICT and HIIT demonstrated significant improvements in behavioral components, including attention deficit, hyperactivity, and impulsivity (all P < 0.0001). HIIT showed superior effects on attention deficit compared to MICT (P = 0.008). Both HIIT (P < 0.0001) and MICT (P = 0.028) improved correct responses (CR) in the Go task compared to the control group. HIIT also outperformed the control group in erroneous responses (ER) (P = 0.022) and correct reaction time (P = 0.027) in the Go task. In the No-Go task, HIIT showed superiority over the control group in both CR (P = 0.013) and ER components.

Conclusion: This study highlights the comparative efficacy of MICT and HIIT as nonpharmacological interventions for children with ADHD. HIIT, in particular, demonstrated superior benefits for attention deficits, suggesting its potential as a targeted adjunctive treatment. These findings may inform the development of exercise programs to enhance the quality of life and daily functioning of children with ADHD.

What is known: • Physical exercise has been explored as a complementary intervention for ADHD, with evidence suggesting its potential to improve symptoms such as inattention, hyperactivity, and impulsivity. • Moderate-intensity continuous training (MICT) has shown positive effects on cognitive and behavioral outcomes in children with ADHD.

What is new: • High-intensity interval training (HIIT) demonstrated superior benefits over MICT in improving attention deficits in children with ADHD. • Both HIIT and MICT significantly improved behavioral inhibition, with HIIT showing additional advantages in reducing erroneous responses and enhancing reaction times in cognitive tasks.

Given the importance of carbohydrates during pregnancy and the limited evidence on the impact of its excessive intake on offspring neurodevelopment, this study aimed to assess the associations between maternal glycemic index (GI) and glycemic load (GL) during early and late pregnancy and behavior problems in 4-year-old children, considering potential sex-related differences in susceptibility to maternal diet. This observational study included 188 mother-child pairs from the ECLIPSES study. GI and GL were estimated from a validated food frequency questionnaire. Offspring behavior was assessed using the Child Behavior Checklist 1.5-5. Multivariable linear and logistic regression analyses were employed to assess the association between GI, GL, and child behavior. Children of mothers in the highest tertile of GL during the first trimester of pregnancy showed elevated scores of both internalizing (β = 5.77; 95% CI, 2.28-9.26) and externalizing (β = 3.95; 95% CI, 0.70-7.19) problems, including anxiety and depression problems, withdrawn, attention problems, aggressive behavior, and attention-deficit/hyperactivity problems, as well as total (β = 5.24; 95% CI, 1.71-8.77) and autism spectrum problems (β = 3.30; 95% CI, 1.11-5.50). Similarly, higher odd ratios were observed for internalizing (OR = 2.37; 95% CI, 1.09-5.18), externalizing (OR = 3.46; 95% CI, 1.49-8.00), and total problems (OR = 3.83; 95% CI, 1.68-8.71). These associations were more pronounced in girls. No associations were observed during the third trimester. Regarding GI, no associations were found for the evaluated outcomes in any of the trimesters.

Conclusion: These findings indicated that elevated maternal GL during the early pregnancy, but not later stages, was associated with adverse behavioral outcomes in offspring.

What is known: • Carbohydrate intake is important during pregnancy as glucose is the main energy source for an optimal fetal brain development. • Elevated prenatal glycemic index and glycemic load have been associated with adverse offspring outcomes but their impact on behavioral development remains insufficiently explored.

What is new: • A high maternal glycemic load during pregnancy may increase the risk of behavioral impairments in preschool-aged offspring. • Female offspring may be more vulnerable to behavioral disturbances to elevated maternal glycemic load during gestation.
