Background: The overall prognosis for patients with metastatic malignant melanoma remains poor. However, careful staging and identification of patients with limited metastatic disease offers the opportunity for surgical salvage and improved survival for selected patients.
Methods: We reviewed the experience over the last 17 years at our institute with isolated pulmonary metastasectomy in 86 patients with advanced malignant melanoma.
Results: Our data demonstrate an overall median time to relapse of approximately 8.4 months and a median survival of 35 months. The 5-year survival rate is estimated at 33%, and 16% remain continuously free of disease after a median follow-up of 35 months. Resection of properly staged and evaluated patients with limited pulmonary metastases appears to convey a significant survival benefit. Patients with a single metastasis fare best.
Conclusions: These encouraging results offer a rationale for the careful follow-up of resected patients. One third of all relapses will be limited and additional surgery contributes to their overall survival.

Introduction: Stenotrophomonas maltophilia is an opportunistic pathogen associated with various nosocomial infections and is known for its intrinsic multidrug resistance. This study aims to provide a comprehensive overview of the epidemiology and resistance patterns of S. maltophilia in China from 2014 to 2021.

Background: Cryoballoon ablation has been widely performed in patients with paroxysmal atrial fibrillation (AF). In some challenging pulmonary veins (PVs), the procedure requires additional touch-up applications against the residual conduction gaps. It implies that there could exist difficult sites to cover with standard cryoballoon applications (CBAs), resulting in resistant conduction gaps (RCGs).

Background: Tropheryma whipplei pneumonia is an infrequent medical condition. The clinical symptoms associated with this disease are nonspecific, often resulting in misdiagnosis or missed diagnosis. Therefore, sharing and summarizing the experiences in the diagnosis and treatment of this disease can deepen global understanding and awareness of it.

Background: Metagenomic next-generation sequencing (mNGS) has emerged as a promising tool in clinical practice due to its unbiased approach to pathogen detection. Its diagnostic performance in pulmonary tuberculosis (PTB), however, remains to be fully evaluated.
Objective: This study aims to systematically review and Meta-analyze the diagnostic accuracy of mNGS in patients with PTB.

Introduction: The ability to detect pathogenic bacteria before the onsets of severe respiratory symptoms and to differentiate bacterial infection allows to improve patient-tailored treatment leading to a significant reduction in illness severity, comorbidity as well as antibiotic resistance. As such, this study refines the application of the non-invasive Secondary Electrospray Ionization-High Resolution Mass Spectrometry (SESI-HRMS) methodology for real-time and early detection of human respiratory bacterial pathogens in the respiratory tract of a mouse infection model.
Methods: A real-time analysis of changes in volatile metabolites excreted by mice undergoing a lung infection by Staphylococcus aureus or Streptococcus pneumoniae were evaluated using a SESI-HRMS instrument.
