AI Article Synopsis

  • Bronchoscopic lung volume reduction (BLVR) is a common treatment for advanced emphysema, but not all patients qualify for it, prompting this study to evaluate lung volume reduction surgery (LVRS) as an alternative for these individuals.
  • The study involved 67 patients who underwent LVRS between March 2018 and December 2022, revealing improvements in lung function, with significant increases in forced expiratory volume and decreases in residual volume post-surgery.
  • While LVRS showed a low mortality rate and manageable complications, long-term follow-up is recommended to assess the lasting benefits for patients not suitable for or who failed BLVR treatment.

Article Abstract

Background: Bronchoscopic lung volume reduction (BLVR) has supplanted surgery in the treatment of patients with advanced emphysema, but not all patients qualify for it. Our study aimed to investigate the outcomes of lung volume reduction surgery (LVRS) among patients who either failed BLVR or were not candidates for it.

Methods: We conducted a retrospective analysis of patients who underwent LVRS for upper lobe-predominant emphysema at a single tertiary center between March 2018 and December 2022. The main outcomes measures were preoperative and postoperative respiratory parameters, perioperative morbidity, and mortality.

Results: A total of 67 LVRS recipients were evaluated, including 10 who had failed prior valve placement. The median patient age was 69 years, and 35 (52%) were male. All procedures were performed thoracoscopically, with 36 patients (53.7%) undergoing bilateral LVRS. The median hospital length of stay was 7 days (interquartile range, 6-11 days). Prolonged air leak (>7 days) occurred in 20 patients. There was one 90-day mortality from a nosocomial pneumonia (non-COVID-related) and no further deaths at 12 months. There were mean improvements of 10.07% in forced expiratory volume in 1 second and 4.74% in diffusing capacity of the lung for carbon monoxide, along with a mean decrease 49.2% in residual volume ( < .001 for all). The modified Medical Research Council dyspnea scale was improved by 1.84 points ( < .001).

Conclusions: LVRS can be performed safely in patients who are not candidates for BLVR and those who fail BLVR and leads to significant functional improvement. Long-term follow-up is necessary to ensure the sustainability of LVRS benefits in this patient population.

Objective: To investigate the effectiveness of 12-weeks hybrid virtual coaching on health-related quality-of-life (HrQoL) in patients with stable COPD.

Methods: We equipped all patients with a CAir Desk for telemonitoring, the intervention group additionally received hybrid virtual coaching through the built-in smartphone. The multimodal intervention based on the Living well with COPD programme, containing educational content, physical activity coaching, and home-based exercises.

This study aimed to investigate the effect of Fuzheng Yiai Decoction (FZYA) on epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) drug resistance in lung adenosquamous carcinoma (ASC). The expression of thyroid transcription factor 1 (TTF1) and p63 in tumor cells was observed by immunofluorescence staining. Meanwhile, 25 nude mice successfully inoculated with the human lung ASC cell line NCI-H596 were randomly divided into five groups, namely, the model, gefitinib, low-, medium-, and high-dose FZYA with gefitinib groups.

Background: Traditionally, pediatric pneumonia is diagnosed through clinical examination and chest radiography (CXR), with computed tomography (CT) reserved for complications. Lung ultrasound (LUS) has gained popularity due to its portability and absence of ionizing radiation. This study evaluates LUS's accuracy compared to CXR in diagnosing pneumonia in children.

Background Chronic obstructive pulmonary disease (COPD) is a progressive respiratory condition characterised by airflow limitation and reduced exercise capacity. The Six-Minute Walk Test (6MWT) and Two-Minute Walk Test (2MWT) are commonly used to assess functional exercise capacity in COPD patients. This study aims to evaluate the correlation between the distance covered in the 2MWT and 6MWT with spirometric indices (such as Forced Expiratory Volume in 1 second (FEV₁), Forced Vital Capacity (FVC), and FEV₁/FVC) in COPD patients.

Modeling aerosol dynamics in the airways is challenging, and most modern personalized tools consider only a single inhalation maneuver through less than 10% of the total lung volume. Here, we present an modeling pipeline to produce a device that preserves patient-specific upper airways while approximating deeper airways, capable of achieving total lung volumes over 7 liters. The modular system, called TIDAL, includes tunable inhalation and exhalation breathing capabilities with resting flow rates up to 30 liters per minute.
