1. Global ARDS subphenotyping: separating apples from oranges.
This Thorax piece addresses the need to standardize and harmonize ARDS subphenotype definitions globally to reduce heterogeneity in trials and facilitate translation of biology into targeted therapies and trial enrichment strategies.
Impact: Clarifies the conceptual and practical barriers to implementing ARDS subphenotypes across cohorts and trials, which is crucial for designing more precise therapies and trial enrichment.
Clinical Implications: Encourages harmonized biomarker and clinical-data collection for ARDS to allow subphenotype-based enrollment or targeting in future trials; not immediately practice-changing but important for trial design and biomarker-driven therapies.
Key Findings
- Advocates for global harmonization of ARDS subphenotype definitions and methods to reduce heterogeneity across studies.
- Highlights methodological differences (biomarker panels, timing, statistical approaches) that impede cross-cohort subphenotype validation.
- Calls for standardized data elements, harmonized biospecimen protocols, and collaborative consortia to enable subphenotype-guided trials.
Methodological Strengths
- Synthesis of international perspectives and methodological pitfalls related to ARDS subphenotyping.
- Practical recommendations for harmonization and consortium-building to enhance reproducibility.
Limitations
- Not an original empirical study — no new primary data or validation cohorts presented.
- Implementation recommendations may be challenging across diverse resource settings.
Future Directions: Prospective harmonized cohort studies with shared biomarker panels and pre-specified statistical plans to validate subphenotypes, followed by subphenotype-stratified interventional trials.
2. Global ARDS subphenotyping: separating apples from oranges.
A call for international standardization of ARDS subphenotypes to enable reproducible classification across cohorts and to facilitate biomarker-driven trial designs and targeted therapies.
Impact: Frames a research agenda to reduce heterogeneity in ARDS studies and to accelerate translation of subphenotype findings into trials.
Clinical Implications: Not directly practice-changing but sets priorities for data harmonization that will permit future subphenotype-based therapeutic trials.
Key Findings
- Emphasizes inconsistency in current subphenotyping methods (timing, biomarkers, statistical clustering).
- Recommends shared core data elements and biospecimen handling protocols to allow cross-study validation.
- Suggests collaborative consortia and prospective harmonized cohorts as next steps.
Methodological Strengths
- Provides pragmatic roadmap for harmonization and validation across cohorts.
- Highlights specific methodological pitfalls to avoid in subphenotyping studies.
Limitations
- Lacks presentation of new empirical data or quantification of the proposed harmonization benefits.
- Practical implementation may be limited by variable resource settings and existing legacy datasets.
Future Directions: Develop consensus minimum datasets, standardized biomarker panels, and pilot multicenter harmonized cohorts to enable subphenotype validation and interventional trials.
3. Severe Malaria and Mechanical Ventilation in Pregnancy: The Crucial Role of Fetal Doppler in Monitoring Fetal Well-Being.
Single-case report of a 33-week pregnant woman with severe malaria requiring mechanical ventilation; serial fetal Doppler velocimetry showed reassuring umbilical artery and middle cerebral artery flows without signs of fetal hypoxia, supporting feasibility of fetal Doppler surveillance during maternal invasive ventilation.
Impact: Provides practical evidence that fetal Doppler can be used serially during maternal invasive ventilation, an under-reported clinical scenario, and compiles sparse literature on this issue.
Clinical Implications: Supports incorporation of serial fetal Doppler assessment into monitoring plans for pregnant patients requiring invasive ventilation, encouraging individualized ventilator settings with close fetal surveillance; highlights need for multidisciplinary perinatal critical care.
Key Findings
- Fetal Doppler velocimetry during maternal mechanical ventilation showed normal umbilical artery and middle cerebral artery flow patterns without evidence of fetal hypoxia.
- Literature review found fewer than a dozen reports of pregnant patients on mechanical ventilation, with little specific evidence on fetal Doppler indices during maternal ventilation.
- Individualized maternal ventilatory management combined with serial fetal assessment may support favorable perinatal outcomes in such cases.
Methodological Strengths
- Detailed physiologic monitoring (serial Doppler velocimetry) during an uncommon clinical scenario.
- Includes a concise literature review placing the case in context of published reports.
Limitations
- Single case report — limited generalizability.
- No long-term neonatal follow-up or standardized ventilatory parameter testing to define optimal settings.
Future Directions: Prospective registries or multicenter case series collecting standardized maternal ventilator settings, fetal Doppler indices, and neonatal outcomes to define best practices and thresholds for intervention.
