Nationwide Outcomes After Thoracoscopic Versus Open Resection of Congenital Pulmonary Airway Malformations in Newborns

Purpose: Elective resection of congenital pulmonary airway malformations (CPAM) has been debated for decades and varies significantly between individual surgeons. However, few studies have compared outcomes and costs associated with thoracoscopic and open thoracotomy approaches on a national level. This study sought to compare nationwide outcomes and resource utilization in infants undergoing elective lung resection for CPAM. Materials and Methods: The Nationwide Readmission Database was queried from 2010 to 2014 for newborns who underwent elective surgical resection of CPAM. Patients were stratified by operative approach (thoracoscopic versus open). Demographics, hospital characteristics, and outcomes were analyzed using standard statistical tests. Results: A total of 1716 newborns with CPAM were identified. Elective readmission for pulmonary resection was performed in 12% (n = 198), with 63% of resections completed at a different hospital than the newborn stay. Most resections were thoracoscopic (75%), compared to only 25% via thoracotomy. Infants treated with thoracoscopic resection were more often male (78% versus 62% open, P = .040) and were older at the time of resection. Patients who had an open thoracotomy experienced a higher rate of serious complications (40% versus 10% thoracoscopic, P < .001), including postoperative hemorrhage, tension pneumothorax, and pulmonary collapse. Readmission costs were higher for infants treated via thoracotomy (P < .001). Conclusion: Thoracoscopic lung resection for CPAM is associated with lower cost and fewer postoperative complications than thoracotomy. Most resections are performed at different hospitals than the place of birth, which may affect long-term outcomes from single institutional studies. These findings may be used to address costs and improve future evaluations of elective CPAM resections.

Difference between SARS-CoV-2, seasonal coronavirus, influenza, and respiratory syncytial virus infection in solid organ transplant recipients

BACKGROUND

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been raging since the end of 2019 and has shown worse outcomes in solid organ transplant (SOT) recipients. The clinical differences as well as outcomes between respiratory viruses have not been well defined in this population.

METHODS

This is a retrospective cohort study of adult SOT recipients with nasopharyngeal swab or bronchoalveolar lavage PCR positive for either SARS-CoV-2, seasonal coronavirus, respiratory syncytial virus (RSV) or influenza virus from January 2017 to October 2020. The follow up period was 3 months. Clinical characteristics and outcomes were evaluated.

RESULTS

A total of 377 recipients including 157 SARS-CoV-2, 70 seasonal coronavirus, 50 RSV and 100 influenza infections were identified. The most common transplanted organ was kidney 224/377 (59.4%). Lower respiratory tract infection (LRTI) was found in 210/377 (55.7%) and the risk factors identified with multivariable analysis were SARS-CoV-2 infection, steroid use, and older age. Co- and secondary infections were seen in 77/377 (20.4%) recipients with bacterial pathogens as dominant. Hospital admission was seen in 266/377 (67.7%) recipients without significant statistical difference among viruses, however, ICU admission, mechanical ventilation and mortality were higher with SARS-CoV-2 infection. In the multivariable model, the risk factors for mortality were SARS-CoV-2 infection and older age.

CONCLUSIONS

We found higher incidence of ICU admission, mechanical ventilation, and mortality among SARS-CoV-2 infected recipients. Older age was found to be the risk factor for lower respiratory tract infection and mortality for SARS-CoV-2, coronaviruses, RSV and influenza virus groups.
