Background: Echocardiography is a non-invasive test that is readily used to detect pulmonary hypertension associated with bronchopulmonary dysplasia (BPD-PH) and right ventricular failure (RVF). However, the most feasible, reproducible and accurate parameters to measure and use for guidance in addressing patient care have not been established and may differ between subspecialties. Methods: We surveyed members of the BPD Collaborative to determine how different care providers clinically evaluate infants for BPD-PH and RVF. Perceived challenges and obstacles that limit the utility of echocardiography are also reported. Results: Of the 108 survey respondents from ~45 centers, 55.6% were neonatologists, 18.5% were pediatric pulmonologists or pediatric intensive care physicians, 15.7% were pediatric cardiologists or pulmonary hypertension specialists, and 10.2% were other providers. Responses revealed discrepancies between specialists concerning the use of standard echocardiographic protocols and parameters that can be measured serially with relative ease, metrics that should be used to best define and distinguish the severity of BPD-PH or RVF, and parameter values that should be used to determine whether changes in PH-targeted medical therapies, hemodynamic or respiratory support are needed. Free text responses identified patient-, protocol-, cardiology-, technician-, and BPD-PH definition-related obstacles that may limit the reliable utility of echocardiography. Conclusions: Although most providers agree that echocardiography is feasible and of value, variability exists between subspecialists and centers, suggesting the need for improved standardization of imaging protocols and BPD-PH definition, consistent test interpretation, and effective communication of results to improve the reproducibility and accuracy of echocardiography in infants with BPD.

Background: Daily, perhaps for hours at a time, pacifiers are put in baby’s mouths for the primary purpose of soothing. A causal relationship exists between the use of pacifiers and the development of malocclusions and disturbances to the cranio-facial-respiratory complex (CFRC). Finite element analysis (FEA) has enabled us to understand how pacifier bulbs behave under negative pressure and tongue movement in the mouth. It is now realized that the design and size of pacifiers should be based on infant and toddler biometrics of the maxillary palatal width and should contribute to proper oral function and development. Attention has shifted toward the interaction between the pacifier shield, the lips, chin and developing tempro-mandibular joint (TMJ). Free mandibular motion is essential to normal TMJ development, essential to maintaining airway space and promoting forward mandibular growth. This is especially relevant in infants with retrognathia, when shield pressure may restrict free movement of the jaw and anterior mandibular advancement. Conclusions: When the pacifier shield interacts with the chin, it impacts the growth and development of the infant mandible and airway physiology. Interference with free movement of the mandible must be made a functional concern in design of the pacifier shield. Technological advances in smartphone photogrammetry now make development of non-invasive diagnostic tools that can advantage the future oral health of children.

Background: Early motor milestones play a critical role in shaping developmental trajectories across motor, cognitive, social, and functional domains. Increasing evidence indicates that motor competence facilitates environmental exploration, learning opportunities, and social engagement during infancy and early childhood. Methods: The present scoping review aimed to map and synthesize the existing evidence on early motor interventions in children aged 0–6 years across diverse pediatric populations. A comprehensive literature search was conducted across PubMed, Scopus, and Web of Science. Studies were selected based on predefined inclusion criteria, and data were extracted and synthesized using a descriptive and thematic approach. Results: A total of 30 studies were included, encompassing a wide range of populations, including preterm infants, children at risk of cerebral palsy, and typically developing children. Across studies, early motor interventions were associated with improvements in motor outcomes and, in many cases, broader developmental domains such as cognition and social interaction. Intervention effectiveness appeared to be influenced by factors such as timing, intensity, task specificity, and caregiver involvement. Conclusions: The review provides a cross-population synthesis of early motor interventions and proposes a conceptual framework that integrates shared mechanisms underlying effective intervention across diverse pediatric groups. This approach offers a more unified understanding of how early motor interventions influence developmental trajectories beyond diagnosis-specific perspectives.

Background/Objectives: Mycoplasma pneumoniae (MP) is a frequent cause of community-acquired pneumonia, but it is increasingly recognized for extrapulmonary complications, specifically Mycoplasma pneumoniae-induced rash and mucositis (MIRM). This systematic review aims to comprehensively assess the frequency of clinical features, diagnostic criteria and outcomes of oral mucositis in patients with confirmed MP infection. Methods: A systematic review was conducted following PRISMA guidelines across PubMed, Web of Science and Scopus, covering the period 2015–2025. Inclusion criteria encompassed in vivo studies, case reports, and case series in English focusing on MP-associated mucositis. Methodological quality was assessed using JBI checklists for case-based evidence and the Newcastle–Ottawa Scale for cohort studies. Two clinical cases were reported. Results: Out of 242 identified records, 42 studies were included, involving 140 patients with a notable male predominance (62%). Oral involvement was reported in 92.9% of cases, often characterized by severe ulcerations, hemorrhagic crusting, and debilitating pain. Intensive Care Unit admission was required in 21.5% of cases due to severe systemic or mucosal disease, with 14.3% necessitating parenteral nutrition. Quality assessment indicated moderate-to-high methodological rigor across most included studies. Conclusions: MIRM represents a significant clinical entity where oral mucositis is a dominant feature, often preceding or overshadowing respiratory symptoms. Early recognition by oral health professionals is crucial to avoid misdiagnosis, ensure appropriate multidisciplinary care, and implement supportive or immunomodulatory therapies that reduce morbidity and hospitalization length.

Background/Objectives: Exclusive breastfeeding offers optimal benefits for infant nutrition and health and increases maternal involvement, bonding and interactions. This study aimed to explore breastfeeding practices among mothers in Romania and identify risk factors associated with low exclusive breastfeeding rates. Methods: A cross-sectional online survey was conducted between September and December 2025, targeting mothers in Romania via social media platforms. The questionnaire, developed specifically for this study, collected data on sociodemographic characteristics, birth and neonatology variables, hospital practices, feeding intentions, community influences, and breastfeeding outcomes. Responses were analyzed using Fisher’s exact tests and multivariable logistic regression. Results: A total of 357 complete questionnaires were analyzed. Cesarean section was the most frequent mode of delivery (54.6%), while immediate mother–infant contact after birth was reported by only 35.6% of mothers, and breastfeeding initiation within the first hour occurred in 10.6% of cases. Overall, 49.3% of mothers reported exclusive breastfeeding, 35.3% mixed feeding, and 15.4% exclusive formula feeding. Women who delivered in private hospitals reported earlier mother–infant contact, more frequent encouragement to initiate breastfeeding, and earlier breastfeeding initiation compared with those delivering in public hospitals. Preterm birth was associated with delayed breastfeeding initiation, reduced rooming-in, and lower rates of exclusive breastfeeding up to six months. In multivariable logistic regression, rooming-in was independently associated with higher odds of exclusive breastfeeding (aOR = 2.798, 95% CI: 1.779–4.401), while lack of lactation support was associated with lower odds (aOR = 0.546, 95% CI: 0.302–0.987). No significant associations were observed for timing of initial maternal–infant contact (aOR = 1.084, 95% CI: 0.679–1.733) or encouragement from medical staff to initiate breastfeeding (aOR = 1.207, 95% CI: 0.721–2.020). Conclusions: Our study highlights current breastfeeding practices and associated hospital factors in Romania. However, significant challenges remain in supporting and encouraging mothers to optimally feed their infants. Additional investment and bold policy action are needed to promote and support breastfeeding from the first hour of life, for both term and preterm infants, in all maternity hospitals in Romania.

Background/Objectives: Sickle cell disease (SCD) is the most prevalent inherited pediatric hematologic disease. Pain is the most common complaint and primary reason for emergency care. Effective coping is critical to improved quality of life for individuals with SCD and other chronic illnesses. Hope, engendered by provision of comprehensive care, may explain the positive impact of effective coping and improved health outcomes. The relevance of effective coping skills and hope’s impact on repeated hospitalizations and/or length of hospitalization stay (LOS) among adolescents with SCD is considered. A regional, comprehensive pediatric sickle cell center (RCPSCC) provided the services. Methods: Patients with SCD, ages 13 through 21 years seen in a university RCPSCC (URCPCC-SCD), completed surveys: a general scale providing a broad range of positive and maladaptive coping-related issues, and KIDCOPE, a standardized scale measuring pediatric coping strategies. Medical records were reviewed for frequency of hospitalization and length of stay (LOS) for the eight months before study entry. Results: Thirty-four URCPCC-SCD outpatients, mean/median age of 16 years, entered the study, and data were analyzed for 33. All reported some sense of future hopefulness, and almost half reported feeling “tense or wound up” most of the time. Use of avoidant or negative coping strategies in response to daily stress correlated positively with increased LOS. Conclusions: Youths with SCD require effective coping strategies to improve self-efficacy and related hope for brighter futures. Individualized, comprehensive treatment and support to families and individuals at risk for sickle cell crisis are uniquely offered in a URCPCC-SCD. Their contributions to service delivery and clinical outcome are expected to enhance hope, mitigate prolonged hospitalizations, and improve adherence to treatment (N = 268).

Background and Objectives: Kawasaki disease (KD) is an acute systemic vasculitis in children, and approximately 10–20% of patients develop resistance to intravenous immunoglobulin (IVIG), which is associated with an increased risk of coronary artery complications. Natural killer (NK) cells play an important role in innate immune regulation, but the temporal dynamics of NK-cell regulatory receptors during KD and their relationship with IVIG response remain unclear. Materials and Methods: In this prospective observational study, we performed longitudinal immunophenotyping in children with KD treated at a tertiary referral center. Peripheral blood samples were obtained before IVIG administration (D0) and at three follow-up timepoints after treatment (D2, D14, and D56). NK-cell subsets and receptor expression—including the activating receptor NKG2D and inhibitory receptor NKG2A—were analyzed using multiparameter flow cytometry. Associations with IVIG response were evaluated using Firth penalized logistic regression for baseline predictors and linear mixed-effects models to assess longitudinal immune trajectories. Results: A total of 69 patients with KD were included, of whom 17 (24.6%) were classified as IVIG resistant. Baseline NK-cell subsets and receptor expression did not differ significantly between IVIG-sensitive and IVIG-resistant patients, although the NKG2D/NKG2A ratio tended to be lower in resistant patients (median 2.51 vs. 3.34, p = 0.054). Longitudinal mixed-effects analysis demonstrated significant temporal changes in NK-cell regulatory signaling following IVIG therapy. Both NKG2A (P(time) = 0.019) and NKG2D (P(time) < 0.001) expression showed significant time effects across the disease course. Importantly, the NKG2D/NKG2A ratio demonstrated a significant time-by-group interaction (P(interaction) = 0.030), indicating divergent trajectories of activating and inhibitory NK-cell signaling according to IVIG response. At the convalescent phase (D56), IVIG-resistant patients showed significantly higher NKG2A expression (p = 0.038) and a lower NKG2D/NKG2A ratio (p = 0.023) than IVIG-sensitive patients. Conclusions: While baseline NK-cell immunophenotypes were not associated with IVIG response, longitudinal analysis revealed that IVIG-resistant patients exhibited a distinct immune trajectory, characterized by increased NKG2A expression and a lower NKG2D/NKG2A ratio during the convalescent phase. These findings suggest that differences in IVIG responsiveness may be related to alterations in immune regulatory processes during the resolution phase of inflammation. However, the clinical implications of these findings remain to be established and require validation in larger, multicenter studies with longitudinal outcome data.

Introduction. Bronchiolitis is the leading cause of Pediatric Intensive Care Unit (PICU) admission for lower respiratory tract infection in infants. Although survival has improved, concerns remain regarding potential long-term functional impairments, including alterations in psychomotor development, learning, and behavior. This study aimed to describe the epidemiological and clinical characteristics of children admitted to the PICU for bronchiolitis and to evaluate their functional outcomes at 12-month follow-up. Methods. A retrospective descriptive cohort study was conducted, including all patients admitted to the PICU for bronchiolitis during the 2021–2022 period. Epidemiological, clinical, microbiological, and laboratory data were collected. Functional health status was assessed using the Pediatric Overall Performance Category (POPC), Pediatric Cerebral Performance Category (PCPC), and Functional Status Scale (FSS) at PICU discharge and 12 months. Changes in functional status were categorized as improved, stable, or worsened. Exploratory unadjusted analyses were performed to describe differences between outcome groups. Results. A total of 164 patients were included (43.9% female), with a median age of 51 days (IQR 26.25–118.5). Respiratory syncytial virus was identified in 79.7% of cases. Invasive mechanical ventilation was required in 31.1% of patients, and 45.7% developed complications during PICU admission. Mortality was 0.6%. At 12 months, functional deterioration was observed in 14.6% of patients according to POPC, 16.5% according to PCPC, and 3.6% according to FSS. Higher proportions of functional deterioration were observed among patients with underlying medical conditions, those requiring invasive mechanical ventilation, those with complications, and those with longer PICU and hospital stays, particularly in the PCPC scale. Conclusions. Most children admitted to the PICU for bronchiolitis showed stable or improved functional status at 12 months. However, a subset experienced functional deterioration, more frequently observed in patients with greater clinical severity and complexity during admission. These results support the need for further studies to better characterize long-term outcomes and to identify children who may benefit from closer follow-up.

Background/Objectives: Abnormal general movements (GMs) in high-risk infants are among the most sensitive early predictors of cerebral palsy (CP) and other neurodevelopmental disorders. This study described changes in the quality of GMs over time in high-risk infants who received the Early Intensive Stojčević–Polovina Rehabilitation Method (EIR–SPM). The EIR–SPM is a rehabilitation method designed for children with CP, those at risk of developing CP, and children with other developmental disabilities. In high-risk infants, it is initiated within the first three months of corrected age, preferably while writhing movements (WMs) are still present. Methods: This study was conducted in eight high-risk infants with abnormal WMs and structural brain injury. The EIR–SPM was initiated between 41 and 47 weeks postmenstrual age (PMA) and was applied until 60 weeks PMA. Prechtl’s General Movements Assessment (GMA), the Detailed GM score, and the Motor Optimality Score–Revised (MOS–R) were assessed. Results: During the writhing period, two infants showed a poor repertoire (PR) pattern and six showed a cramped–synchronized (CS) pattern of GMs; at follow-up, three showed PR, and five showed CS. During the fidgety period, two infants showed normal fidgety movements (F+), two sporadic fidgety movements (sFM), one infant showed abnormal fidgety movements (aFM), and three showed absent fidgety movements (F−) at the first assessment, while at the second assessment, three infants showed F+, two sFM, one aFM, and two F−. The median Detailed GM score increased from 12 (range 11–17) to 13.5 (range 11–19; p = 0.068). The median MOS–R increased from 17.0 (range 12–24) to 19.5 (range 17–27) between the two fidgety assessments (p = 0.027). Conclusions: Improvements in motor repertoire, reflected by increased MOS–R scores, were observed during the EIR–SPM initiated in the writhing period. Larger controlled studies are needed to confirm these preliminary observations.

Background/Objectives: Ankle–foot orthoses (AFOs) are commonly used to improve gait in children with cerebral palsy (CP), but their effect on specific gait patterns is underreported. This study evaluates the utilization of the Gait Pattern Classification System for Children with Spastic CP (GaP-CP) to investigate the effects of ankle–foot orthoses on gait kinematics, spatio-temporal parameters and the energy cost of walking. Methods: In this retrospective study, 66 ambulatory children with spastic CP underwent 3D gait analysis with and without AFOs or functional electrical stimulation. Gait patterns were classified according to GaP-CP. AFOs were articulated, flexible, or rigid. Thirty-six children also performed a 5 min walk test with gas exchange measurements. Step length, walking speed, and the energy cost of walking were calculated. Gait kinematics were analyzed with statistical nonparametric mapping. Non-parametric statistics were used to investigate orthotic effects for the total group and for each gait pattern. Results: Ankle kinematics improved in swing phase and initial contact (10 degrees less plantarflexion, p < 0.05) for the total group, dropfoot and genu recurvatum. During the stance phase, reduced knee extension in genu recurvatum (by 3 degrees, p < 0.05) and increased knee extension in crouch (by 3 degrees, p < 0.05) were observed. Median changes in non-dimensional step length were clinically significant (>0.039, p ≤ 0.02, effect size ≥ 0.55) for the total group and the dropfoot, genu recurvatum, and crouch subgroups, while changes in most gait indices, walking speed and the energy cost of walking were not clinically significant. Conclusions: The combined use of GaP-CP and kinematic analysis provided new insights into the effects of ankle–foot orthoses on gait. Articulated and flexible orthoses may not have provided adequate support for genu recurvatum and crouch gait, showing a potential value in gait pattern specific orthotic design to optimize gait kinematics.
