The present work aimed to develop GRADE-based operational guidelines for therapeutic hypothermia, offering neonatologists a structured approach for identifying, treating, and monitoring newborns throughout the procedure. A panel of experts appointed by the Italian Society of Neonatology conducted a systematic review (PROSPERO registration CRD420250651303) of randomized controlled trials evaluating the effects of therapeutic hypothermia on neurodevelopmental outcomes. Literature searches were performed across Medline, Cochrane, Scopus, Embase, and Web of Knowledge databases, and studies were assessed using the Cochrane Risk-of-Bias 2 tool. Recommendations were formulated through consensus meetings following GRADE methodology and subsequently validated by an external multidisciplinary panel. Eight randomized controlled trials, encompassing a total of 1,843 newborns, met the inclusion criteria. Based on a comprehensive evaluation of study indications, characteristics, and outcomes, evidence-based recommendations were established. The risk-of-bias assessment revealed an even distribution between studies categorized as low and moderate risk. The resulting guidelines present a structured protocol covering all phases of therapeutic hypothermia - timing, clinical setting, management, and follow-up - and include proposals for expanding its application. To facilitate clinical implementation, the guidelines are accompanied by summary tables, graphical flowcharts, and algorithms designed for immediate use in neonatal intensive care settings. The GRADE-based recommendations presented here, now adopted as the Italian national clinical guidelines for therapeutic hypothermia in newborns, provide an evidence-driven and standardized framework to optimize neonatal care.

Although severe asthma affects only around 10% of pediatric patients, this subgroup bears a disproportionate share of the clinical and economic burden. Long-term disease control relies on regular monitoring and education, yet traditional follow-up in specialist outpatient clinics may not be sufficient. Advances in telemedicine and digital health offer new opportunities for remote monitoring, treatment adherence assessment, and patient education, but evidence for their use in moderate-to-severe pediatric asthma remains fragmented. METHODS: We systematically reviewed evidence on telemedicine and innovative technologies for moderate-to-severe asthma in children, adolescents, and young adults. Using GRADE, we assessed study quality and synthesized findings. A multidisciplinary panel applied a structured consensus process to develop tailored recommendations, considering evidence strength, feasibility, equity, resources, and patient preferences. RESULTS: Of the 27,551 records retrieved, 55 studies met the inclusion criteria (38 randomized controlled trials, 17 observational). Despite substantial heterogeneity in design, populations, and interventions, digital health tools—such as smartphone applications, online platforms, and remote monitoring devices—were generally feasible, well accepted, and often linked to improved quality of life, symptom control, treatment adherence, and reduced exacerbations and hospitalizations. Effects on pulmonary function were inconsistent. Increased healthcare contacts reported in some studies were interpreted by experts as earlier exacerbation recognition rather than clinical deterioration. Educational interventions via digital platforms were strongly valued by the panel, despite low-quality supporting evidence. Overall, evidence quality was limited by methodological weaknesses, varying outcome definitions, and heterogeneity in telemedicine tools, precluding meta-analysis. Sustainability challenges included costs, device access, provider workload, and the need for robust community-based care networks. Key barriers were unequal digital access, limited provider training, poor interoperability, and privacy concerns. CONCLUSION: Telemedicine may enhance adherence, empower self-management, and enable early detection of deterioration in moderate-to-severe pediatric asthma. Conditional recommendations were made for its use, particularly during exacerbations. Future high-quality studies with standardized outcomes, long-term follow-up, and economic analyses are needed to strengthen the evidence base and guide sustainable implementation. </p>","PeriodicalId":14511,"journal":{"name":"Italian Journal of Pediatrics","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13267218/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147771646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Western countries, HUS complicates about 15% of STEC infections, which are responsible for acute bloody diarrhea (ABD) in at least 6–7% of cases in children (rising to over 15% during late summer). The widespread use of molecular microbiology techniques enables the diagnosis of STEC infection before HUS onset in an increasing number of patients, creating a potential window of preventive and therapeutic opportunities. Given the rapid progression of the disease, all children with ABD should be tested for Shiga toxin (Stx) encoding genes as early as possible. Stx-positive patients should then be closely monitored for HUS development by urine dipstick, to detect hemoglobinuria.This proactive diagnostic approach creates the opportunity to anticipate the application of measures that have already been proven to mitigate the severity of HUS, among which stands the early and generous fluid administration, but most importantly opens a window to explore preventive and therapeutic interventions. In detail, even though antibiotics are not historically recommended in STEC infections, recent data suggest a promising potential preventive role for bacteriostatic agents (e.g., azithromycin) during the initial stages of the infection.The aim of the present contribution is to share this approach to ABD and STEC infection as endorsed by the Italian scientific societies actively engaged in this area (AMCLI, SIGENP, SIMEUP, SIN, SIP, SIPPS, SITIP) through an intersocietal consensus.

As most pathological variants are de novo variants, early prediction of phenotypes and prognosis is challenging, and the genotype-phenotype correlation remains unclear. METHOD: We retrospectively analyzed the clinical and genetic data of 50 children with SCN1A variant-related epilepsy to explore the relationship between variant characteristics (location, in silico prediction scores), seizure characteristics, and phenotypes. RESULTS: This study included 50 children with SCN1A variant-related epilepsy, among whom 86.0% (43/50) had onset before the age of 1, 86.0% (43/50) exhibited fever sensitivity, and 68.0% (34/50) were accompanied by developmental delay; 36.0% (18/50) experienced status epilepticus(SE), 56.0% (28/50) had cluster seizures, and 48.0% (24/50) showed abnormal electroencephalogram(EEG) within one year of onset.

However, the association between COVID-19 infection and anti-M antibody development in pediatric patients remains unexplored. METHODS: This retrospective matched case-control study included 31 anti-M positive pediatric patients and 31 matched anti-M negative controls with NN phenotype from October 2022 to May 2025. Anti-M isotypes (IgM/IgG) were distinguished using saline and dithiothreitol-preserved plasma methods, followed by titer determination and IgG subclass analysis. Plasma cytokines were quantified by flow cytometry. COVID-19 infection history within 2 years was recorded. RESULTS: Anti-M positive patients had significantly higher COVID-19 infection rates than controls (54.84% vs. 19.35%, OR = 5.06, P = 0.008); this association remained significant after adjustment for age and sex (adjusted OR = 5.35, 95% CI: 1.67–17.17, P = 0.005). Among those with IgG antibodies, anti-M IgG titers inversely correlated with the interval since COVID-19 infection (r = -0.63, P = 0.008). Reactive IgG (IgG1/IgG3) exhibited significantly higher titers than inactive IgG (median 64 vs. 4, P < 0.001), with all high-titer cases (≥ 64) exclusively in the reactive group (11/31, 35.48%). Anti-M positive patients showed elevated IL-8 (P = 0.006) and IL-12p70 (P = 0.029), and unexpectedly lower bilirubin levels (P < 0.01), suggesting metabolic adaptation rather than hemolysis. CONCLUSION: COVID-19 infection is significantly associated with anti-M alloantibody development in NN-phenotype children, with over one-third reaching clinically significant titers. These findings suggest that enhanced antibody screening should be considered for pediatric transfusion candidates with recent viral infections, although the single-center design with modest sample size (31 pairs) warrants multi-center validation. </p>","PeriodicalId":14511,"journal":{"name":"Italian Journal of Pediatrics","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13255407/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147771637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
