1. Impact of Antenatal Dexamethasone on Respiratory Outcomes in Late Preterm Infants in a Vietnamese Tertiary Hospital: A Randomised Controlled Trial.
In an open-label RCT of 294 women at risk of late preterm delivery, antenatal dexamethasone reduced the need for neonatal respiratory support (15% vs 24.5%, p=0.04) and lowered neonatal unit admissions. No increase in maternal postnatal infection or neonatal hypoglycemia was observed; jaundice requiring phototherapy was higher in controls.
Impact: Provides randomized evidence from a LMIC setting supporting antenatal steroids specifically in late preterm gestations to reduce immediate neonatal respiratory morbidity.
Clinical Implications: Consider antenatal dexamethasone for women at risk of late preterm delivery to reduce neonatal respiratory support and admissions, while monitoring for neonatal jaundice.
Key Findings
- Respiratory support after birth was less frequent with dexamethasone (15%) versus control (24.5%), p=0.04.
- Neonatal unit admissions were significantly lower in the dexamethasone group (p=0.01).
- No increase in maternal postnatal infection or neonatal hypoglycemia with dexamethasone.
- Jaundice requiring phototherapy was higher in controls.
Methodological Strengths
- Randomized controlled design with intention-to-treat analysis
- Prospectively registered trial (NCT05841121)
Limitations
- Open-label design may introduce performance bias
- Single-center setting limits generalizability
Future Directions: Multicenter, blinded RCTs comparing dexamethasone vs betamethasone in late preterm and evaluating longer-term neurodevelopmental outcomes.
2. Optimizing communication for ultrafast lung cancer biomarker testing: the UTOPIA pilot study.
A prospective, MTB-centered workflow delivered comprehensive NGS reports for NSCLC within 72 hours in 100% of 96 patients, with a 1% NGS failure rate. Actionable alterations were found in 45.8% (EGFR 24%, KRAS G12C 8.3%, ALK 6.3%, MET exon 14 4.2%, BRAF V600E 2.1%, RET 1%), demonstrating feasibility of ultrafast precision diagnostics.
Impact: Demonstrates an operational model achieving clinically meaningful turnaround times for comprehensive biomarker testing, which can reduce time-to-treatment in NSCLC.
Clinical Implications: Implement structured MTB triage and daily cross-functional communication to achieve ≤72h NGS TAT, enabling timely initiation of targeted therapies.
Key Findings
- 100% of NGS reports (96/96) met the 72-hour turnaround target.
- NGS failure rate was 1%.
- Actionable alterations identified in 45.8%: EGFR (24%), KRAS G12C (8.3%), ALK fusions (6.3%), MET exon 14 skipping (4.2%), BRAF V600E (2.1%), RET fusion (1%).
Methodological Strengths
- Prospective cohort with predefined operational metrics (TAT, failure rate)
- Integrated MTB-centered triage and standardized communication checklists
Limitations
- Single-center study limits generalizability
- No randomized comparison to standard workflow or measurement of clinical outcomes (e.g., time-to-treatment)
Future Directions: Multicenter implementation trials to assess scalability, time-to-treatment impact, and patient outcomes; cost-effectiveness and equity analyses.
3. Unravelling the exposome of severe exacerbations of obstructive respiratory diseases in France.
Using nationwide matched case-control data (473,990 COPD; 187,332 asthma), severe exacerbations were linked to exposure to extreme cold temperatures and NO2 exceedances over WHO standards. Findings highlight modifiable environmental risk factors and the utility of open data integration for respiratory public health.
Impact: Identifies population-level, modifiable environmental drivers of severe exacerbations across COPD and asthma, informing prevention strategies and policy.
Clinical Implications: Cold exposure and NO2 exceedances warrant targeted alerts, protective measures (heating, masks, indoor air quality), and regional action to mitigate exacerbation risk in vulnerable patients.
Key Findings
- Nationwide matched case-control analysis included 473,990 COPD and 187,332 asthma patients (2018–2022).
- Extreme cold temperature exposure was associated with increased odds of severe exacerbations.
- Exceedances of WHO NO2 standards were associated with higher exacerbation risk.
- Study demonstrates feasibility of linking hospital and open environmental datasets for exposome analyses.
Methodological Strengths
- Very large, nationwide matched case-control design
- Integration of clinical and open environmental datasets
Limitations
- Retrospective design with potential residual confounding
- Potential exposure misclassification from area-level environmental data
Future Directions: Prospective cohort studies with personal exposure monitoring and evaluation of targeted interventions (e.g., cold alerts, NO2 reduction) on exacerbation outcomes.
