Summary
July’s ARDS literature converged on precision recognition and individualized care, alongside immunometabolic and lipid–epigenetic mechanisms of hyperinflammation. An externally validated, open-source NLP pipeline substantially improved ARDS detection from clinical text, while a randomized trial and physiologic studies reinforced personalized ventilation strategies. Mechanistic work highlighted the IL-35/JAK–STAT axis and an oxPL→AKT→EZH2 pathway that epigenetically silences IL-10, nominating druggable nodes. Population-level syntheses clarified corticosteroid parameters in critical illness and compared noninvasive neonatal respiratory modalities, and structural virology enabled high-throughput assays against Nipah virus polymerase.
Selected Articles
1. Open-source computational pipeline flags instances of acute respiratory distress syndrome in mechanically ventilated adult patients.
An interpretable, open-source NLP/ML pipeline operationalizing the Berlin Definition identified ARDS from radiology reports and clinician notes with 93.5% sensitivity and a 17.4% false-positive rate on an external dataset, greatly exceeding documentation rates.
Impact: Directly addresses ARDS under-recognition with an externally validated tool ready for EHR integration and prospective evaluation.
Clinical Implications: Can be embedded in EHRs to trigger timely lung-protective ventilation, proning, and specialty consults; prospective monitoring is needed to manage false alerts and quantify impact.
Key Findings
- External validation showed 93.5% sensitivity with 17.4% false-positive rate.
- Outperformed clinical ARDS documentation (22.6%), revealing under-recognition.
- Interpretable classifiers applied to radiology reports and clinician notes.
2. Cryo-EM structures of Nipah virus polymerases and high-throughput RdRp assay development enable anti-NiV drug discovery.
Resolved multi-strain cryo-EM structures of Nipah polymerase and created radiolabeled and non-radioactive high-throughput polymerase assays, establishing a practical pipeline for direct-acting antiviral discovery.
Impact: Combines structural virology and assay innovation to accelerate drug discovery against a high-consequence respiratory pathogen with ARDS-relevant clinical manifestations.
Clinical Implications: Enables rational HTS and medicinal chemistry optimization of polymerase inhibitors, potentially shortening timelines to in vivo testing and early clinical candidates.
Key Findings
- Defined full-length and truncated Nipah L–P polymerase structures across strains.
- Identified conserved PRNTase loops and domain interactions and showed back-priming activity.
- Developed sensitive radiolabeled and fluorescence/luminescence HTS-ready assays.
3. Interleukin-35 regulates the differentiation of regulatory T cells through the JAK-STAT pathway and influences glutamine metabolism in ARDS.
Mechanistic human and preclinical data show IL-35 promotes Foxp3+ Treg differentiation, rewires glutamine/TCA metabolism, and reduces lung inflammation via STAT phosphorylation; effects are reversed by JAK/SYK inhibition.
Impact: Defines a tractable immunometabolic axis linking cytokine signaling to metabolic rewiring and inflammation control in ARDS.
Clinical Implications: Supports early-phase testing of IL-35 modulation or JAK–STAT targeting therapies in ARDS with metabolic phenotyping and safety monitoring.
Key Findings
- IL-35 increased Foxp3 expression and regulatory T cell differentiation.
- Rewired glutamine and TCA metabolites indicative of immunometabolic shifts.
- Cerdulatinib reversed IL-35 effects, implicating JAK/STAT dependence.
4. Efficacy and safety of corticosteroids in critically ill patients: a systematic review and meta-analysis.
Meta-analysis of 43 RCTs (n=10,853) showed corticosteroids reduced short-term mortality and improved ventilation duration, ventilator-free days, and oxygenation, with optimal effects when started early, at low dose, and for ≥7 days.
Impact: Provides high-level, actionable parameters (timing, dose, duration) for steroid use in severe respiratory critical illness including ARDS.
Clinical Implications: Consider early, low-dose, prolonged corticosteroids in selected phenotypes with vigilant adverse effect monitoring.
Key Findings
- Reduced short-term mortality across 43 RCTs (RR 0.85).
- Improved ICU/hospital stay, MV duration, ventilator-free days, and oxygenation.
- Best outcomes with early initiation, low dose, and duration ≥7 days.
5. Non-invasive respiratory support in preterm infants as primary mode: a network meta-analysis.
A network meta-analysis of 61 trials (n=7,554) suggests NIPPV and NIHFV may reduce treatment failure/intubation versus CPAP as primary noninvasive support, though overall certainty is low and effects on chronic lung disease are minimal.
Impact: Most comprehensive comparative synthesis guiding first-line noninvasive support choices in preterm infants and clarifying methodological gaps.
Clinical Implications: Where resources permit, consider NIPPV/NIHFV to reduce early failure, ensuring comparable mean airway pressures and cautious interpretation of low-certainty evidence.
Key Findings
- NIPPV reduced treatment failure versus CPAP (very low certainty).
- NIHFV reduced treatment failure versus CPAP (low certainty).
- Minimal effect on moderate–severe chronic lung disease; pressure matching often absent.
