Burnout Syndrome in Lung Transplant Physicians.

Objective: Burnout syndrome is common in physicians, but little is known about burnout in lung transplant physicians specifically. The purpose of this study was to explore burnout and its relationship to job factors and depression in lung transplant physicians.Design: A cross-sectional study that included lung transplant pulmonologists and surgeons was performed via electronic survey.Setting: The lung transplant physicians surveyed practiced worldwide.Methods: The survey incorporated questions about demographics and job characteristics as well as the Maslach Burnout Inventory and Patient Health Questionnaire-2. Burnout was defined by high emotional exhaustion or depersonalization.Participants: Ninety physicians worldwide completed the survey.Results: Of the 90 physicians who completed the entire survey, 44 (48.9%) had burnout with 38 (42.2%) having high emotional exhaustion, 15 (16.7%) having high depersonalization, and 9 (10.0%) with both. Of the respondents, 14 (15.6%) had high risk of depression, and of these, 13 also had high emotional exhaustion. There was a positive correlation between depression score and emotional exhaustion score (P=0.67, P<0.001). Depression was more common in surgeons compared with pulmonologists (35.7% versus 11.8%, P=0.02). There was a trend toward more burnout by emotional exhaustion in physicians with more versus less work experience (68.4% versus 31.6%, P=0.056).Conclusions: Emotional exhaustion is common in lung transplant physicians and is associated with depression and a negative impact on life.

Safety and utility of indwelling pleural catheters in lung transplant recipients.

INTRODUCTION: The safety and efficacy of indwelling pleural catheters (IPCs) in lung allograft recipients is under-reported. METHODS: We performed a multicenter, retrospective analysis between 1/1/2010 and 6/1/2022 of consecutive IPCs placed in lung transplant recipients. Outcomes included incidence of infectious and non-infectious complications and rate of auto-pleurodesis. RESULTS: Seventy-one IPCs placed in 61 lung transplant patients at eight centers were included. The most common indication for IPC placement was recurrent post-operative effusion. IPCs were placed at a median of 59 days (IQR 40-203) post-transplant and remained for 43 days (IQR 25-88). There was a total of eight (11%) complications. Infection occurred in five patients (7%); four had empyema and one had a catheter tract infection. IPCs did not cause death or critical illness in our cohort. Auto-pleurodesis leading to the removal of the IPC occurred in 63 (89%) instances. None of the patients in this cohort required subsequent surgical decortication. CONCLUSIONS: The use of IPCs in lung transplant patients was associated with an infectious complication rate comparable to other populations previously studied. A high rate of auto-pleurodesis was observed. This work suggests that IPCs may be considered for the management of recurrent pleural effusions in lung allograft recipients.

Pediatric lung transplantation for COVID-19: Unique clinical and psychosocial barriers.

BACKGROUND: SARS-CoV-2 infection in the age group of 0-17 years contributes to approximately 22% of all laboratory-confirmed SARS-CoV-2 infections. Fortunately, this age group has a lower death rate (0.5 per 100 000) that accounts for only 4% of the total deaths due to COVID-19. Despite the low mortality rate in the pediatric population, children of minority groups represented 78% of the deaths highlighting the existing disparities in access to health care. METHODS: With the emergence of the more contagious COVID-19 variants and the relatively slow pace of vaccination among the pediatric population, it is possible to see more cases of significant lung injury and potential for transplantation for the younger age group. RESULTS: To our knowledge, our patient is the youngest to have undergone lung transplantation for SARS-CoV-2. CONCLUSION: The case presented unique challenges, particularly in relation to timing for listing and psychosocial support for parents who were his decision makers.

Determinants of pre-transplantation pectoralis muscle area (PMA) and post-transplantation change in PMA in lung transplant recipients.

BACKGROUND: This study aimed to determine predictors of pectoralis muscle area (PMA) and assess change in PMA following lung transplantation and its relationship to outcomes. METHODS: A retrospective review of 88 lung transplant recipients at a single center was performed. PMA was determined on a single axial slice from chest computerized tomography. Pectoralis muscle index (PMI) was calculated from the PMA divided by the height squared. RESULTS: PMI decreased post-transplantation (8.1±2.8 cm2 /m2 pre-transplantation, 7.5±2.9 cm2 /m2 at 6 months, and 7.6±2.7 cm2 /m2 at 12 months, P<.05). Chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) were predictors of pre-transplant PMI (ß=-2.3, P=.001 for COPD; ß=2.1, P<.001 for ILD) and percent change in PMI at 12 months post-transplantation relative to baseline (ß=19.2, P=.04 for COPD; ß=-20.1, P=.01 for ILD). Patients in the highest quartile for PMI change at 12 months had fewer ventilator days compared with patients in the other quartiles (P=.03). CONCLUSIONS: Underlying diagnosis was a significant predictor of both pre-transplantation PMI and change in PMI post-transplantation. Further studies of PMI are needed to determine its clinical utility in predicting outcomes following lung transplantation.

Treatment of refractory thrombotic thrombocytopenic purpura with N-acetylcysteine: a case report.

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disease resulting in systemic microvascular thrombosis. The disease is caused by excessive platelet (PLT) adhesion to ultra-large (UL) von Willebrand factor (VWF) multimers inadequately cleaved by the processing enzyme ADAMTS-13. While many cases respond to plasma exchange performed with or without concurrent corticosteroids, treatment of the 10% to 20% of patients with refractory disease is difficult. Experimental studies demonstrating that N-acetylcysteine (NAC) inhibits PLT binding to endothelial cell-secreted and anchored UL VWF multimers suggest that NAC may be useful in the treatment of TTP. CASE REPORT: A 44-year-old woman presented with malaise, confusion, chest and abdominal pain, and transient visual loss. Laboratory results and peripheral blood smear were consistent with TTP. The patient was begun on plasma exchange and corticosteroid treatment, but after 10 days the PLT count was still less than 10.0 × 10(9) /L and she developed a fever. Rituximab was initiated, but the patient's condition worsened and she became comatose. Antibiotics were initiated, but cultures remained sterile. After 3 days of coma and further clinical deterioration, treatment with NAC was begun. The patient received a loading dose of 150 mg/kg NAC intravenously (IV) over 1 hour. Within 18 hours the patient awakened abruptly and began communicating with medical personnel. Plasma exchange, corticosteroids, rituximab, and NAC infusion (150 mg/kg IV over 17 hr daily × 10 days) were continued and by Day 17 the PLT count was more than 50 × 10(9) /L. The patient fully recovered and was discharged on Day 31. CONCLUSION: This is the first complete report of a TTP patient treated with NAC. NAC was a safe and effective supplementary treatment for refractory TTP in this patient.
