Background: Chronic obstructive pulmonary disease (COPD) significantly contributes to global morbidity and mortality. Despite increasing COPD prevalence in Saudi Arabia, knowledge of and barriers to adherence to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines among respiratory therapists (RTs) remain limited. This study assessed RT awareness and barriers to adherence to the updated 2023 GOLD guidelines for COPD management in Saudi Arabia.

Methods: A modified cross-sectional online survey (snowball sampling) was distributed via social media from December 2023 to March 2024. The questionnaire covered eight domains: six assessing knowledge of COPD (overview, diagnosis, stable COPD therapy, pharmacological and nonpharmacological management of COPD and exacerbations, and COPD prevention and comorbidity), one on barriers to guideline adherence, and one on attitudes toward guidelines. A knowledge score (out of 39) was calculated. Descriptive statistics, tests for group differences, and regression analyses were conducted.

Results: Three hundred and twenty-six RTs (65.6% of males) participated. The average knowledge score was 18.9 ± 5.75 out of 39 (49.9% correct answers), indicating low COPD knowledge. Higher scores were associated with more COPD cases and bedside RT roles. While 53.1% of RTs expressed positive attitudes toward guideline utilization, only 16.9% of RTs reported recent use and 12.9% reported consistent use over the past 6 months. Key barriers included limited time for professional development (40.8%) and inadequate educational resources (37.7%).

Conclusion: This study reveals a knowledge gap and suboptimal COPD guidelines adherence among RTs in Saudi Arabia. Knowledge level correlated with COPD cases and RT role. Targeted interventions are needed to improve guideline adherence and COPD care.

Background: Ventilator-associated pneumonia (VAP) is a common complication in intensive care units (ICUs), particularly in patients undergoing prolonged mechanical ventilation. VAP rates vary significantly across regions, with the Middle East and North Africa (MENA) region experiencing relatively high incidences. This study systematically reviews and analyses the efficacy of various VAP prevention strategies in the adult population of the MENA region.

Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines. Electronic databases (PubMed, Scopus, and CINAHL) were searched for studies from January 2004 to May 2024 that investigated VAP prevention strategies in adult ICU patients in the MENA region. Data extraction and quality assessment were performed by multiple independent reviewers. Meta-analysis was carried out using the DerSimonian and Laird random effect models.

Results: A total of 10 randomized clinical trials conducted in Iran and Tunisia were included. The studies evaluated various interventions, including respiratory care programs, oral care protocols, and tracheal suction techniques. Significant reductions in VAP incidence were observed with interventions such as aerosolized colistin and comprehensive oral care (e.g., clove mouthwash). However, certain interventions, such as ondansetron and N-acetylcysteine, did not yield significant benefits.

Conclusion: This meta-analysis highlights effective VAP prevention strategies in the MENA region, with notable improvements in patient outcomes. These findings can potentially help in developing policies and guidelines to enhance VAP prevention efforts across ICUs in the region. Further research is essential to address existing gaps and refine prevention strategies.

Gastrobronchial fistula (GBF) is a rare but serious complication following esophagectomy, associated with high morbidity and mortality. The use of silicone plugs has proven effective in closing bronchial fistulas in other contexts, but its application in GBF has not been widely described. In this article, we report the successful closure of a GBF using a self-made silicone plug under bronchoscopic guidance in a patient with a history of esophagectomy for esophageal cancer. This approach offers a safe, minimally invasive alternative for managing refractory GBF.

Background: To evaluate the perioperative outcomes of hybrid multi-arm robotic-assisted uniportal thoracoscopic surgery (H-URATS) using a laparoscopic stapling device, assess the safety and feasibility of the procedure, and summarize the surgical experience.

Methods: The Department of Thoracic Surgery at Xinjiang Tumor Hospital has performed over 100 H-URATS procedures using endoscopic staplers and the robotic surgery platform. We collected the clinical data and perioperative outcomes from patients undergoing Uniportal Video-assisted Thoracoscopic Surgery (UVATS) and H-URATS between January 2023 and August 2024. Propensity score matching (PSM) was conducted based on clinical characteristics and perioperative outcomes were compared between the two groups after matching.

Results: A total of 395 patients were included, with 109 in the H-URATS group and 286 in the UVATS group. After PSM, each group consisted of 92 patients. There were no significant differences between the H-URATS and UVATS groups in terms of chest drainage duration, postoperative hospital stay, conversion to thoracotomy rate, intensive care unit admission rate, postoperative complication rate, postoperative pathological types, or tumor TNM staging (P > 0.05). The H-URATS group had less intraoperative blood loss compared to the UVATS group (P < 0.001), and more lymph nodes (LNs) and LN stations were dissected in the H-URATS group (P < 0.001).

Conclusion: In terms of short-term results, our study confirms the safety and feasibility of H-URATS as a new minimally invasive technique. It combines the advantages of uniportal thoracoscopy and robotic surgery systems and demonstrates potential benefits in oncological outcomes and complex procedures such as segmentectomies.

A 32-year-old Chinese woman with a cough and bloody sputum was diagnosed with chronic eosinophilic pneumonia. After starting corticosteroid therapy, chest radiography showed improvement in the bilateral infiltrative shadow. However, chest image findings showed worsening of the bilateral infiltrative shadow and pulmonary cavities during the 20 mg/day of oral prednisolone therapy. Transbronchial lung biopsy and bronchoalveolar lavage were repeated, and the patient was diagnosed with pulmonary paragonimiasis. After starting praziquantel treatment, chest radiography findings and clinical symptoms improved. Careful follow-up during corticosteroid therapy is important to judge whether transient improvement and true deterioration of radiological findings.

The pathogenesis of cervical extension of the thymus has been postulated to be incomplete descent of the thymus in the midline of the neck, which is considered normal in children. The thymus normally extends to the neck in approximately two-thirds of children. Ectopic thymus mainly occurs in 1%-13% of the younger population. In this study, we report two cases of asymptomatic neck swelling, one due to cervical extension of the thymus and the other due to a right submandibular ectopic thymus. None of the patients required any intervention. Recurrent suprasternal swelling in children that becomes more pronounced during coughing/crying or Valsalva maneuvers can be more accurately diagnosed using neck ultrasonography and/or magnetic resonance imaging.

A 39-year-old female has postoperative empyema with bronchial stump fistula (BSF) after pneumonectomy due to ineffective tuberculosis chemotherapy. Transpleural reamputation of the right main bronchial stump with simultaneous 8-rib thoracoplasty, 6 attempts at endobronchial valve implantation and thoracostomy have failed to cure BSF and empyema. Consequently, an alternative treatment-transsternal transpericardial wedge-shaped resection of the tracheal bifurcation was performed despite its difficulty and was successful. This clinical case demonstrates the complications of BSF with tuberculosis empyema treatment in spite of there existing many alternative therapies. The need for new more effective treatments is highlighted, as well as safe and less technically difficult interventions which could assist patients with BSF.

Bronchopleural fistula (BPF) is a rare yet severe complication following lobectomy, with no standardized treatment protocol established. We present a case of a 65-year-old male with chronic obstructive pulmonary disease who developed multiple BPFs postresection of the right lower lobe due to lung cancer and with tumor recurrence and metastasis. We employed a comprehensive management strategy comprising rigorous infection control, meticulous chest drainage, antitumor treatment, and targeted deployment of bronchial stents. This approach not only resolved the BPFs but also achieved a complete response of the lung cancer, extending progression-free survival to over 3 years.

Adult patients with chronic respiratory diseases (CRDs) are considered high risk group who are more likely to experience worse clinical outcomes if they acquire viral or bacterial infections. Vaccination is the best preventive tool to reduce the risk of infection and disease occurrence and to reduce the level of severity of complications associated with the various vaccine-preventable infections. These guidelines were developed by the Saudi Thoracic Society task force to emphasize the critical importance of improving the vaccine coverage rates in adult patients with CRD. They are intended to serve as a reference for healthcare practitioners managing CRD patients. The guidelines aimed to review the current knowledge related to vaccination efficacy in adult patients with CRD, based on the recent evidence and recommendations. Integrating the administration of the recommended vaccines in routine healthcare, such as during outpatient visits or before hospital discharge, is crucial for improving the vaccination rates in high-risk patients. The key strategies to address this public health priority include simplifying vaccination guidelines to enhance their accessibility and implementation by healthcare providers, increasing awareness in both the patients and healthcare providers that vaccines are not only intended for children. Additional strategies include maintaining continuous surveillance and advance research to discover novel vaccines. This approach aims to expand the range of preventable diseases and improve overall health and well-being. Vaccine hesitancy remains a significant challenge that necessitates a clear understanding of the community concerns. Providing appropriate education and communication, as well as addressing these concerns, are the crucial steps toward improving vaccine acceptance and uptake. By implementing these guidelines and multifaceted strategies, healthcare systems can optimize vaccine coverage and protection for patients with CRD, reduce the burden of vaccine-preventable complications, and improve the clinical outcomes in this vulnerable population.
