Background: Pulmonary infection is a common clinical complication in children with congenital pulmonary airway malformation (CPAM). Surgical intervention has been proven effective in managing this condition. We aim to evaluate the impact of pulmonary infection on the outcomes of total thoracoscopic procedures in children with CPAM.
Methods: This was a single-center retrospective study. CPAM patients who underwent total thoracoscopic surgery at a tertiary care center from January 2013 to December 2023 were divided into three groups based on pulmonary infection status: non-infection (NI), hidden infection (HI), and pulmonary infection (PI). Clinical characteristics and operation-related outcomes were compared among the groups.
Results: A total of 154 children with CPAM who underwent thoracoscopic surgery were categorized into three groups based on pulmonary infection: the NI group (27 cases), HI group (56 cases), and PI group (71 cases). The conversion rate to thoracotomy was 14.8%, 23.2%, and 29.2% respectively across the three groups. 116 cases were successfully completed thoracoscopically. There were no significant differences in gender distribution among the three groups (p > 0.05), but statistically significant (p < 0.05) in age and weight. Significant differences emerged in operative time and blood loss (p < 0.05), but no significant variations were found in transfusion requirements, chest tube duration, ventilator use duration, or hospital stay length (p > 0.05). In postoperative pulmonary complications, a statistically significant difference was found regarding pneumothorax incidence among all three groups (p < 0.05), whereas no significant differences (p > 0.05) emerged concerning atelectasis or pneumonia incidences across these cohorts.
Conclusions: Pulmonary infection is the most prevalent complication in CPAM and exhibits a high rate of hidden infections, thereby complicating surgical intervention and increasing associated risks. Early thoracoscopic intervention prior to infection manifestation can optimize surgical outcomes and reduce associated complications.

Article Synopsis
- GREM1 is linked to tumor progression and poor prognosis in lung adenocarcinoma (LUAD), which is a common and aggressive form of lung cancer.
- The study uses various analyses, including gene expression data and survival analysis, to demonstrate that higher levels of GREM1 are associated with worse patient outcomes and influence the immune microenvironment.
- Experimental results show that GREM1 promotes LUAD cell growth and movement, highlighting its potential as a target for future therapies in personalized cancer treatment.

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by joint pain, swelling, and stiffness, affecting approximately 1% of the adult population. Tocilizumab (TCZ), a monoclonal antibody targeting the IL-6 receptor, has emerged as an effective treatment for RA. This narrative review provides an update on TCZ's efficacy and safety based on data from randomized controlled trials (RCTs) and real-world evidence (RWE).

COPD is a multifactorial illness characterized by a long-term restriction of airflow and an inflammatory reaction in the lungs. The associated emphysema leads to the breakdown of alveolar proteins and abnormal expansion of the lung air spaces. Chronic bronchitis caused by the same disease can result in increased deposition of structural proteins, narrowing of the airways, and excessive mucus secretion leading to acute exacerbation of COPD (AECOPD).
