1. Static and longitudinal extrauterine growth restriction in very low birth weight infants: prevalence and associated factors.
PMID:日期:2026-09-24Extrauterine growth restriction (EUGR) occurs when preterm infants fail to achieve expected intrauterine growth rates. EUGR is classified as static (body weight < 10th percentile at 36 weeks postmenstrual age (PMA) or longitudinal (weight z-score decline > 1 standard deviation from birth to 36 weeks PMA). This study aimed to determine the prevalence of each type and identify associated factors. This retrospective cohort study included very low birth weight (VLBW) infants admitted to a tertiary-level NICU between January 2020 and December 2023. Infants who died, were transferred before 36 weeks PMA, or had chromosomal or major anomalies were excluded. Of 107 infants, 55 (51.4%) had static EUGR and 35 (32.7%) had longitudinal EUGR. Multivariable analysis identified SGA as the only significant factor associated with static EUGR (aOR 9.01, 95% CI 2.08-39.08, p = 0.003). Delayed achievement of 120 mL/kg/day after day of life 10 showed a positive association with static EUGR but did not reach significance (aOR 2.57, 95% CI 0.93-7.13, p = 0.069). In contrast, delayed full enteral feeding was the only significant factor associated with longitudinal EUGR (aOR 3.98, 95% CI 1.48-10.68, p = 0.006). Agreement between definitions was weak (κ = 0.186, p = 0.019). Static EUGR was strongly associated with SGA status at birth, whereas longitudinal EUGR identified a partially distinct subgroup of infants. Delayed achievement of full enteral feeding was significantly associated with longitudinal EUGR. This finding warrants cautious interpretation, as delayed enteral feeding may serve as a marker of illness severity rather than a direct causal factor.

2. Assessment of pMDI inhaler technique in children and adolescents with cystic fibrosis.
PMID:日期:2026-09-24To assess the quality of pressurized metered-dose inhaler (pMDI) technique among patients with cystic fibrosis (CF) and their caregivers, and identify associated clinical and socioeconomic factors. Cross-sectional study of 146 CF patients (≤ 18 years) followed at a reference center in 2025. Inhaler technique was assessed using a study-specific 11-step checklist with age-based adaptations. Adequate technique required correct performance of ≥ 70% of eligible steps, including all essential steps. Socioeconomic and clinical data were obtained from medical records and structured interviews. The overall adequacy rate was 68.4%. The 0-5-year age group showed higher adequacy than those ≥ 6 years (85.1% vs. 60.6%). Main errors were re-shaking for the second puff in children < 6 lt; 6 years (31.9%) and slow exhalation in those ≥ 6 years (81.8%). Multivariate logistic regression identified early childhood (0-5 years, OR = 5.16; 95% CI: 1.78-14.91; p = 0.002) and family income of 2-3 minimum wages (OR = 0.30; 95% CI: 0.10-0.90; p = 0.032) as independent predictors of technique quality. Nearly one-third of children and adolescents with CF had inadequate pMDI technique (31.6%). Respiratory coordination and re-shaking for the second puff were the main errors identified. Early childhood (0-5 years) was independently associated with better technique, whereas family income of 2-3 minimum wages predicted poorer performance. The developed checklist proved viable for multidisciplinary CF consultations. Longitudinal, multicenter studies using validated instruments are needed to establish causality and assess the impact of systematic educational interventions.

3. Academic achievement map: a clear cognitive route and a promising motor path.
PMID:日期:2026-09-23This study investigates how executive functions, motor coordination, and oral discourse are related to academic performance in children from public schools in Rio de Janeiro. This longitudinal study assessed 75 children at the beginning (T1) and at the end (T2) of a school semester. Working memory was measured by the Digit Span test, eye-hand coordination by the Touch Test Disc (TTD), and oral discourse by non-semantic graph metrics (SpeechGraphs). Academic performance was assessed in Portuguese and Mathematics. Digit Span and TTD showed the strongest correlations with academic performance at T2, while graph metrics obtained from oral discourse were not significant predictors. Digit Span correlated positively with Portuguese (r = 0.505; p < 0.001) and Mathematics (r = 0.388; p = 0.002), while TTD correlated negatively with Portuguese (r = -0.453; p < 0.001) and Mathematics (r = -0.398; p = 0.001), i.e. better motor performance was associated with higher grades. Multiple regression analyses showed that Digit Span predicted Portuguese (β = 0.492; p < 0.001, 24.2% of variance). For Mathematics, both age (β = -0.501; p < 0.001) and Digit Span performance (β = 0.413; p = 0.002) were significant predictors. Working memory is a predictor of academic performance in both Portuguese and Mathematics, and eye-hand coordination also shows significant correlations with school grades, suggesting a relevant relationship between motor skills and learning. These findings highlight the importance of taking an integrated approach to cognitive and motor capacities in the educational context.

4. Cost-effectiveness of oral food challenge in managing cow's milk allergy under the Brazilian Public Health perspective.
PMID:日期:2026-09-22To analyze the cost-effectiveness and cost-utility of using oral food challenge test (OFC) to manage non-IgE-mediated gastrointestinal cow's milk protein allergy (non-IgE-GI-CMPA) in infants within the Brazilian public health system (SUS). A decision model was developed to compare two strategies: 1. 100 % of physicians recommending OFC for diagnosis (D-OFC) and evaluation of oral tolerance (OT-OFC), and 2. OFC performed according to the practices of pediatricians in Brazil (D-OFC indicated by 56 % and 45 % of physicians for mild-to-moderate and severe cases, respectively, and OT-OFC indicated by 93 % of physicians for both cases). The authors assumed that 10 % of parents would refuse the OFC and set the ages of 3.65 and 24 months for model admission and follow-up (time horizon), respectively. Clinical and epidemiological data, primarily from Brazil, data on public health costs, and a 5 % discount rate for both costs and outcomes were used. The effectiveness endpoint was the duration without a cow's milk elimination diet and quality-adjusted life-year (QALY) values of 0.84 (with allergy) and 0.94 (without allergy). GUIDELINE-OFC resulted in average savings of USD 241.98, a gain of +0.019 QALYs, and +70 days without a cow's milk elimination diet per patient. In the probabilistic sensitivity analysis, all cost-effectiveness and 96.5 % of cost-utility simulations demonstrated lower costs and greater effectiveness. Over five years, the public healthcare system would save USD 129 million. Using OFC in infants with non-IgE-GI-CMPA is a dominant strategy, yielding substantial savings for the SUS and potentially improving nutritional status and quality of life.

5. Global burden and inequalities of Hodgkin and non-Hodgkin lymphoma among children aged 0-14 years, 1990-2021: a GBD 2021 analysis with forecasts to 2035.
PMID:日期:2026-09-22Childhood Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) are potentially curable, but outcomes differ across development levels. The authors assessed global burden and inequalities among children aged 0-14 years from 1990 to 2021 and projected burden to 2035. GBD 2021 estimates for 204 locations provided age-standardized incidence, mortality, and disability-adjusted life-year (DALY) rates by sex and Sociodemographic Index (SDI). Estimated annual percentage changes (EAPCs) summarized trends; the slope index of inequality (SII) and concentration index (CII) measured absolute and relative inequalities. An exploratory Country Priority Index (CPI) combined mortality and DALY rates, absolute DALYs, and adverse trajectories. Autoregressive integrated moving average (ARIMA) models generated forecasts. From 1990 to 2021, incidence declined modestly. Mortality declined from 0.152 to 0.095 per 100,000 for HL and from 0.75 to 0.45 for NHL; corresponding DALY rates fell from 12.50 to 7.78 and from 63.38 to 37.83. Boys and low-SDI settings had higher burdens, and SDI was strongly inversely associated with mortality and DALYs. For NHL mortality, the SII improved from -0.91 to -0.61, whereas the CII worsened from -0.38 to -0.49. The CPI ranked Pakistan, Uganda, South Sudan, Zimbabwe, and Nigeria highest. By 2035, projected HL and NHL incidence rates were 0.20 and 0.98, mortality rates 0.08 and 0.35, and DALY rates 6.22 and 27.25 per 100,000, respectively. Childhood lymphoma outcomes improved globally, but relative inequalities remained concentrated in lower-SDI settings. CPI-based prioritization supports investment in diagnosis, treatment, essential medicines, supportive care, and surveillance. Forecasts represent conditional baseline trajectories.

6. Circumcision and continuous antibiotic prophylaxis in preventing recurrent febrile urinary tract infection in boys with high-grade vesicoureteral reflux.
PMID:日期:2026-09-21To evaluate the effectiveness of circumcision and continuous antibiotic prophylaxis (CAP) in preventing febrile urinary tract infection (fUTI) in boys with high-grade primary vesicoureteral reflux (VUR). This retrospective cohort included 114 boys younger than 5 years diagnosed with grades III-V primary VUR between June 2019 and June 2022. Patients were managed with observation (n = 14), CAP alone (n = 23), circumcision alone (n = 38), and combined CAP and circumcision (n = 39). The follow-up duration was 2 years. The incidence of fUTIs in each group was recorded, and associations between conservative management strategies and fUTI recurrence were analyzed. 15 (13.2%) children experienced recurrent fUTIs. Recurrence rates were 42.9% in the observation group, 30.4% in the CAP group, 5.3% in the circumcision group, and 0% in the CAP+ circumcision group. Circumcision-containing groups (circumcision alone and CAP + circumcision) had significantly lower recurrence rates than non-circumcision groups (observation and CAP alone) (p < 0.05). Multivariable Firth-penalized logistic regression confirmed circumcision as an independent protective factor against fUTI recurrence (aOR = 0.09, 95% CI: 0.01-0.98, p = 0.042), while CAP alone showed no significant protective effect (aOR = 0.45, 95% CI: 0.06-3.21, p = 0.421). Circumcision significantly reduced fUTI recurrence in boys with grade III-V primary VUR and may represent an important component of conservative management in this high-risk population, whereas the added value of CAP remains uncertain.

7. Ultraviolet index levels in Recife, Brazil: an ecological study to identify low-erythemal-risk sunlight exposure windows for infants.
PMID:日期:2026-09-19Current pediatric guidelines recommend avoiding direct sun exposure for infants under six months. However, these recommendations may offset other potential benefits of sunlight exposure. The authors aimed to examine the Ultraviolet Index (UVI) levels in Recife, Brazil, particularly during early-morning and late-afternoon periods. Ecological descriptive study using secondary data from the National Institute for Space Research (INPE - UV-Brazil Project). Hourly UVI averages at 6:00, 7:00, 8:00, and 9:00 a.m. and 3:00, 4:00, and 5:00 pm. for the year 2025 were collected, considering seasonal variations (rainy vs. dry season). In Recife (8°S), the mean and maximum UVI remain ≤ 2.0 (low category) until 7:00 a.m. and after 04:00 pm. throughout the year according to WHO classification. During most of the rainy season (May-July), maximum UVI drops below 2.0 after 3:00 pm. In Recife, Northeast Brazil, maximum UVI values are in the WHO low category (≤ 2) until 7:00 a.m. and after 4:00 pm., indicating a low likelihood of acute erythema. However, these ecological data do not establish long-term carcinogenic safety in infants.

9. FEEDSETUP: feeding difficulties spectrum evaluation and treatment up-to-date proposal.
PMID:日期:2026-09-18To organize current knowledge and propose a comprehensive, treatment-focused classification system, called FEDSETUP, that guides clinicians through a stepwise, multidisciplinary approach to pediatric feeding difficulties, emphasizing intervention intensity matched to clinical need and severity. Development of the FEEDSETUP framework was grounded in a systematic approach to evidence synthesis, following PRISMA principles adapted for narrative framework development. Given the multidimensional nature of pediatric feeding difficulties-spanning medical, nutritional, behavioral, and developmental domains-a structured PICO framework was employed to guide literature identification and selection. FEEDSETUP integrates a systematic initial assessment encompassing medical history, dietary evaluation, physical examination, and anthropometry. It categorizes feeding difficulties into distinct yet overlapping domains, including underlying organic disease, typical neophobia, micronutrient deficiency, difficulty concentrating on food, food phobia, and food selectivity. The framework prioritizes primary healthcare as the first line of intervention, with clear criteria for escalation to specialized multidisciplinary teams for more complex or severe cases, including those with Autism Spectrum Disorder comorbidity or Avoidant/Restrictive Food Intake Disorder. FEEDSETUP offers a comprehensive, integrated, and treatment-oriented approach to pediatric feeding difficulties, moving beyond diagnosis-centric models to provide a structured pathway for effective and individualized care across the spectrum of severity. The algorithm provides a practical, evidence-based roadmap for clinicians to ensure timely identification of associated behavioral, nutritional, and organic abnormalities. It facilitates interdisciplinary assessment, reduces diagnostic delays, and promotes coordinated care by matching intervention intensity to clinical presentation, thereby avoiding both under-treatment and over-medicalization.

10. Causal association between allergic diseases and short stature: a mendelian randomization study revealing the potential mediating role of inflammatory proteins.
10. 过敏性疾病与身材矮小之间的因果关联：一项揭示炎症蛋白潜在中介作用的孟德尔随机化研究PMID:日期:2026-09-18Although observational studies have proven a correlation between allergic diseases and short stature (SS), the causal relationship remains unestablished. Furthermore, inflammatory proteins are closely linked with both conditions; their potential mediating role has yet to be elucidated. This study aimed to probe into the causal linkage between allergic diseases and SS and the mediating role of inflammatory proteins. A two-sample MR analysis was employed to explore the causal links between five allergic diseases (allergic rhinitis, childhood asthma, allergic conjunctivitis, atopic dermatitis (AD), and urticaria) and SS. A two-step MR approach was further used to investigate the mediating role of inflammatory proteins. Among the five allergic diseases, MR analysis only identified a suggestive positive correlation between AD and the risk of SS (OR = 1.720, 95%CI: 1.081-2.735, P = 0.022). A suggestive negative association was also found between AD and the level of the inflammatory protein AXIN1 (OR = 0.922, 95%CI: 0.855-0.995, P = 0.037). Mediation analysis revealed that AXIN1 levels potentially mediated 13.5% of the causal pathway between AD and SS risk. A potential positive causal link between AD and SS was revealed, highlighting the potential mediating role of the inflammatory protein AXIN1. These findings provide a scientific basis and a novel potential target for interventions aimed at improving height growth outcomes in patients with allergic diseases.
