Summary
Today's top papers span perioperative risk in smokers, real-world patterns of autoimmune rheumatic disease–associated interstitial lung disease, and a rare neonatal case highlighting ABCA3 surfactant deficiency. Together, they underscore the need for nuanced risk stratification, multidisciplinary diagnostics, and consideration of genetic etiologies in severe respiratory failure.
Research Themes
- Perioperative risk and tobacco exposure
- Autoimmune rheumatic disease–associated interstitial lung disease phenotypes
- Genetic surfactant disorders in neonatal respiratory failure
Selected Articles
1. Risk Stratification of Smokers Undergoing Colorectal Surgery.
In a 239-patient retrospective cohort of current and former smokers undergoing colorectal surgery, 28% experienced major adverse events within 30 days. Independent predictors included chronic obstructive pulmonary disease, and 11% reported concurrent smokeless product use while half had quit prior to surgery.
Impact: The study refines perioperative risk stratification for smokers by considering exposure patterns beyond pack-years and identifying independent predictors. This can inform preoperative counseling and optimization.
Clinical Implications: Incorporate COPD status and detailed tobacco exposure (duration, intensity, cessation history, and smokeless product use) into preoperative risk assessments, and intensify cessation and pulmonary optimization strategies.
Key Findings
- Among 239 smokers undergoing colorectal surgery, 28% had a major adverse event within 30 days.
- Independent predictors of increased complications included chronic obstructive pulmonary disease.
- 11% concurrently used smokeless tobacco products; half had quit smoking prior to surgery.
Methodological Strengths
- Clearly defined 30-day composite endpoint capturing major cardiopulmonary and thrombotic outcomes
- Multivariable assessment identifying independent predictors
Limitations
- Retrospective single-cohort design susceptible to residual confounding
- Abstract does not report effect sizes or full list of independent predictors
Future Directions: Prospective validation to quantify effect sizes for exposure patterns, evaluate timing of preoperative cessation, and assess whether targeted optimization reduces 30-day complications.
2. Interstitial Lung Disease Associated with Autoimmune Rheumatic Diseases: An Experience from Türkiye.
This multicenter retrospective study of 212 ARD-ILD patients in Türkiye found systemic sclerosis to be the most common underlying rheumatic disease (53.8%), with NSIP as the predominant radiological pattern (71.7%). The cohort also included IPAF and other connective tissue diseases, underscoring the need for multidisciplinary management.
Impact: By detailing disease distribution and imaging patterns in ARD-ILD, the study provides practical epidemiologic context that informs screening and diagnostic prioritization.
Clinical Implications: Expect NSIP predominance in ARD-ILD, particularly in systemic sclerosis; prioritize HRCT-based pattern recognition and coordinated rheumatology–pulmonology care. Consider IPAF in appropriate phenotypes.
Key Findings
- Among 212 ARD-ILD patients, systemic sclerosis was the most common underlying disease (53.8%).
- NSIP was the predominant radiological pattern (71.7%), with definite UIP at 13.7% and probable UIP at 8.5%.
- The cohort included RA (22.2%), Sjögren's syndrome (6.6%), inflammatory myopathy (7.5%), IPAF (4%), UCTD (3.8%), and SLE (1.9%).
Methodological Strengths
- Multidisciplinary, tertiary-center collaboration across rheumatology and pulmonology
- Relatively large ARD-ILD cohort with detailed radiologic phenotyping
Limitations
- Retrospective descriptive design without longitudinal outcome data
- Potential referral/selection bias inherent to tertiary centers
Future Directions: Prospective longitudinal studies to link radiologic patterns and serologies with outcomes, and to evaluate multidisciplinary care pathways.
3. Progressive respiratory failure in a term neonate with ABCA3 surfactant deficiency: Beyond the common causes of respiratory distress.
This case report describes progressive respiratory failure in a term neonate attributed to ABCA3 surfactant deficiency, emphasizing that genetic causes should be considered when typical etiologies of neonatal respiratory distress do not explain the course.
Impact: Highlights a rare but important genetic etiology for severe neonatal respiratory failure, prompting earlier genetic evaluation when clinical trajectories diverge from common patterns.
Clinical Implications: In term neonates with progressive respiratory failure unresponsive to standard management for TTN/RDS/air leak, consider genetic surfactant disorders like ABCA3 deficiency and pursue appropriate diagnostic workup.
Key Findings
- Progressive respiratory failure occurred in a term neonate beyond common causes such as TTN, RDS, or air leak.
- The clinical course was attributed to ABCA3 surfactant deficiency, a rare genetic cause of neonatal respiratory distress.
Methodological Strengths
- Detailed clinical characterization highlighting divergence from common neonatal respiratory distress etiologies
- Identification of a specific rare disease mechanism guiding diagnostic considerations
Limitations
- Single case report limits generalizability
- Abstract does not detail genetic testing methods or management outcomes
Future Directions: Develop diagnostic algorithms incorporating early genetic testing for persistent neonatal respiratory failure and evaluate targeted therapies in ABCA3-related disease.
