Summary

An updated meta-analysis of randomized trials indicates that early nasal intermittent positive pressure ventilation outperforms nasal CPAP in preterm RDS by reducing invasive ventilation and bronchopulmonary dysplasia. A pediatric case series shows bronchoscopic interventions can resolve central airway obstruction after congenital heart surgery to enable ventilator weaning. A single-patient report suggests molecular hydrogen may modulate immunity and reduce fatigue in SLE/Sjögren’s with ILD, warranting controlled studies.

European journal of pediatrics · 2025PMID: 40579569

Across 14 RCTs (n=1,755), early NIPPV reduced invasive ventilation (RR 0.53) and bronchopulmonary dysplasia (RR 0.48) versus NCPAP in preterm RDS. IV reduction was consistent across GA, birthweight, and surfactant subgroups, while BPD reduction reached significance when stratified by GA. The authors call for higher-quality evidence to solidify recommendations.

Impact: This meta-analysis aggregates randomized evidence to clarify the comparative effectiveness of NIPPV vs NCPAP in preterm RDS, directly addressing clinically important outcomes (IV and BPD).

Clinical Implications: Consider early NIPPV as initial noninvasive respiratory support for preterm infants with RDS to reduce progression to invasive ventilation and possibly BPD, while recognizing the need for standardized protocols and further high-quality trials.

Key Findings

  • Meta-analysis of 14 RCTs involving 1,755 preterm infants with RDS.
  • NIPPV reduced invasive ventilation versus NCPAP (RR 0.53, 95% CI 0.43–0.64; P<.001).
  • NIPPV reduced BPD (RR 0.48, 95% CI 0.29–0.79; P=.004); IV reduction consistent across GA, birthweight, and surfactant subgroups; BPD reduction significant when stratified by GA.

Methodological Strengths

  • Comprehensive multi-database search spanning 1980–2022 with randomized trials only
  • Random-effects meta-analysis with predefined subgroup analyses and dual independent data extraction

Limitations

  • Overall certainty limited by varying trial quality; authors call for higher-quality evidence
  • BPD reduction was not uniformly significant across all subgroups except GA strata

Future Directions: Conduct large, CONSORT-compliant RCTs with standardized NIPPV protocols and individual patient data meta-analyses to confirm BPD benefits and identify responders.

UNLABELLED: The aim of the present systematic review was to determine whether non-invasive intermittent positive pressure ventilation (NIPPV), as initial respiratory support for preterm infants with respiratory distress syndrome (RDS), reduces the incidence of invasive ventilation (IV) and bronchopulmonary dysplasia (BPD) more effectively than nasal continuous positive airway pressure (NCPAP). We systematically searched Medline, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) for records published between 1980 and February 2022. RCTs comparing early NIPPV with NCPAP as initial respiratory support in preterm infants with RDS were included. Two reviewers independently extracted data. Pooled relative risks (RRs) with 95% confidence intervals (CI) were calculated using random-effects meta-analysis. Subgroup analyses were performed for infants receiving surfactant and stratified by gestational age (GA) or birth weight (BW). The primary outcomes were the incidence of IV and BPD. A total of 14 randomized clinical trials (RCTs) involving 1755 infants were included. Compared with NCPAP, early NIPPV significantly reduced the incidence of IV (risk ratio [RR], 0.53; 95% CI, 0.43-0.64; P < .001) and the incidence of BPD (RR, 0.48; 95% CI, 0.29-0.79; P = .004). The reduction in the incidence of IV remained statistically significant across multiple subgroups: GA > 30 weeks (RR, 0.41; 95% CI, 0.27-0.63; P < .001) and GA ≤ 30 weeks (RR, 0.31; 95% CI, 0.20-0.48; P < .001); infants treated with surfactant (RR, 0.60; 95% CI, 0.43-0.83; P = .002); BW ≤ 1500 g (RR, 0.54; 95% CI, 0.38-0.77; P < .001) and BW > 1500 g (RR, 0.53; 95% CI, 0.36-0.77; P = .001). However, the reduction in the incidence of BPD was significant only in subgroups stratified by GA: GA > 30 weeks (RR, 0.40; 95% CI, 0.18-0.90; P = .03) and GA ≤ 30 weeks (RR, 0.33; 95% CI, 0.14-0.75; P = .008). CONCLUSION: Early NIPPV appears superior to NCPAP for reducing the incidence of IV and BPD in preterm infants with RDS. Nevertheless, higher-quality evidence is needed for definitive recommendations. WHAT IS KNOWN: • Nasal intermittent positive pressure ventilation (NIPPV) delivers cyclical peak pressure support and may outperform nasal continuous positive airway pressure (NCPAP). While some randomized controlled trials (RCTs) show NIPPV reduces invasive ventilation rates compared to NCPAP, its effect on bronchopulmonary dysplasia (BPD) incidence remains inconclusive. WHAT IS NEW: • NIPPV appears superior to NCPAP in reducing the incidence of IV and BPD in preterm infants with respiratory distress syndrome (RDS) as initial noninvasive respiratory support.

2. Bronchoscopic Management of Central Airway Obstruction in Children after Heart Surgery.

36Level IVCase series
The Thoracic and cardiovascular surgeon · 2025PMID: 40578812

In a retrospective series of six children with central airway obstruction after congenital heart surgery, bronchoscopic interventions (balloon/mechanical dilatation, stenting) enabled successful ventilator weaning in four. There was no procedure-related mortality; complications included inability to place a stent in one case and granulation requiring conversion to a biodegradable stent in another.

Impact: Addresses a rare but critical cause of ventilator weaning failure in pediatric cardiac surgery and demonstrates feasibility and safety of bronchoscopic strategies.

Clinical Implications: In selected post–cardiac surgery pediatric patients with central airway obstruction, early bronchoscopic evaluation with consideration of dilatation or stenting can facilitate weaning, with attention to stent selection and monitoring for granulation.

Key Findings

  • Retrospective case series of six children (4 months–6 years) with postoperative central airway obstruction.
  • Interventions: balloon dilatation (n=1), mechanical dilatation (n=3), stenting (n=2).
  • Outcomes: four successfully weaned; two nonprocedural deaths (pneumonia-related ARDS and cardiac arrest); no procedure-related mortality; one failed stent placement due to instability; one granulation requiring switch to biodegradable stent.

Methodological Strengths

  • Clear procedural categorization (dilatation vs stenting) with outcome reporting
  • Use of both rigid and flexible bronchoscopy under standardized anesthetic conditions

Limitations

  • Small, single-center retrospective series without a control group
  • Limited follow-up details and heterogeneity of interventions

Future Directions: Prospective multicenter registries and standardized algorithms to guide selection of dilatation vs stenting and to evaluate long-term airway patency and weaning outcomes.

Central airway stenosis following congenital heart malformation surgery is a rare but significant cause of postoperative weaning failure. In selected cases, bronchoscopic interventions are effective treatment options for managing these kind of airway obstructions and achieving successful weaning.The data of six pediatric patients who were unable to be weaned from mechanical ventilation due to central airway obstruction following congenital heart malformation surgery were retrospectively analyzed. Rigid and flexible bronchoscopies were performed under general anesthesia for six patients.Six patients (4 males and 2 females; age range: 4 months to 6 years) with an airway obstruction after surgery due to congenital heart malformations included the study. Three patients had an obstruction of the left main bronchus, two of the right main bronchus, and one of bilateral main bronchus. Balloon dilatation was applied to one patient, mechanical dilatation was applied to three patients, and airway stent was applied to two patients. Two of six patients died from nonprocedural causes (acute respiratory distress syndrome due to pneumonia and cardiac arrest due to severe heart failure) and four patients were weaned successfully from mechanical ventilation and they were still alive during the follow-up period. No procedural-related mortality was seen in the study population. In one patient, stent placement could not be performed due to desaturation and hemodynamic instability during the procedure, and in another patient, granulation tissue developed due to a covered metallic stent, and the metallic stent was removed and replaced with a biodegradable stent.In selected cases, bronchoscopic interventions offer efficient approach to managing airway obstructions due to congenital heart malformation surgery.

3. Molecular Hydrogen as an Adjuvant Therapy in Comorbid Sjögren's Syndrome, SLE, and ILD: A Case Report on Immune Modulation and Fatigue Reduction.

29.5Level VCase report
In vivo (Athens, Greece) · 2025PMID: 40579023

A 69-year-old woman with Sjögren’s, SLE, and ILD experienced symptom relief, improved imaging, and favorable T/B cell shifts after adjunct molecular hydrogen therapy, enabling steroid taper and reduced nocturnal oxygen. The uncontrolled single-case nature limits inference but signals potential immunomodulatory benefit.

Impact: Provides hypothesis-generating evidence that molecular hydrogen may modulate immune dysregulation and fatigue in complex autoimmune ILD.

Clinical Implications: Not practice-changing; may justify pilot trials of molecular hydrogen as an adjunct in autoimmune ILD with careful safety monitoring and standardized outcomes.

Key Findings

  • Single-patient adjunct therapy with molecular hydrogen alongside corticosteroids and immunomodulators.
  • Clinical improvements included resolution of xerostomia, insomnia, dyspnea, chest pain, and dizziness over several months.
  • Correlated with favorable shifts in T and B cell subsets, improved pulmonary imaging, reduced inflammatory markers, steroid tapering, and decreased nocturnal oxygen need.

Methodological Strengths

  • Longitudinal clinical, immunologic, and imaging assessments reported in detail
  • Real-world adjunct use with documentation of steroid taper and oxygen reduction

Limitations

  • Single case without control; causality cannot be inferred
  • Concomitant therapies (including high-dose vitamin C) confound attribution; placebo effect possible

Future Directions: Design randomized pilot studies to assess safety, dosing, and biomarkers of response for molecular hydrogen in autoimmune ILD.

BACKGROUND/AIM: Systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS) are chronic autoimmune diseases that often coexist. They share features such as systemic inflammation and multi-organ involvement and typically require long-term immunosuppressive treatment. However, long-term use of immunosuppressants can cause serious side effects, highlighting the need for adjunct therapies. Molecular hydrogen (H CASE REPORT: We present the case of a 69-year-old female diagnosed with Sjögren's syndrome, SLE, and ILD. The patient exhibited chronic symptoms, including xerostomia, xerophthalmia, and respiratory distress, for which she had been receiving corticosteroids and immunomodulatory therapy. Given the persistent disease burden and concerns regarding long-term immunosuppressive therapy, molecular hydrogen therapy was introduced as an adjunctive treatment. Over several months, the patient experienced notable clinical improvements, including resolution of xerostomia, insomnia, dyspnea, chest pain, and dizziness. These symptomatic improvements correlated with favorable immunological shifts in T and B cell subsets, enhanced pulmonary imaging findings, and a reduction in inflammatory markers. Additionally, the patient reported a significant decrease in fatigue, allowing corticosteroid tapering and less reliance on nighttime oxygen. Ongoing hydrogen therapy with high-dose vitamin C maintained disease stability and improved quality of life. CONCLUSION: This case highlights the potential of molecular hydrogen (H
