Abstract
Obesity at the time of lung transplant is associated with decreased survival. How providers manage obesity after lung transplantation is unknown. We performed an international survey of lung transplant providers to assess beliefs and practices regarding post-transplant obesity management. Eighty-one providers initiated the survey and 73 (90%) completed the full survey. Respondents were primarily North American-based pulmonary physicians. Nearly all providers believe treating obesity improves quality of life (99%) and survival (95%) after lung transplantation, but that only 41% of patients attempting weight loss are successful. While respondents nearly always recommend diet (96%), exercise (92%), and dietician consultation (89%), they less frequently recommend prescription weight loss medications (29%) or bariatric surgery (11%). Lung transplant providers are motivated to treat obesity in transplant recipients. However, there is a gap between general obesity treatment guidelines and lung transplant practice. Additional training, education, and trials in this population could address this gap.

Abstract
Patients with connective tissues disease (CTD) are often on immunomodulatory agents before lung transplantation (LTx). Till now, there's no consensus on the safety of using these agents perioperative and post-transplant. The International Society for Heart and Lung Transplantation-supported consensus document on LTx in patients with CTD addresses the risk and contraindications of perioperative and post-transplant management of the biologic disease-modifying antirheumatic drugs (bDMARD), kinase inhibitor DMARD, and biologic agents used for LTx candidates with underlying CTD, and the recommendations and management of non-gastrointestinal extrapulmonary manifestations, and esophageal disorders by medical and surgical approaches for CTD transplant recipients.

Abstract
Background Valganciclovir (VGCV) and ganciclovir (GCV) are commonly used to prevent CMV in at-risk lung transplant recipients (LTRs). Because renal function changes frequently in the post-transplant setting, antiviral under-dosing may occur. We sought to determine the frequency of GCV/VGCV under-dosing and its impact on CMV-related outcomes among LTRs. Methods We conducted a retrospective cohort study of all adult LTRs with a CMV seropositive donor (D+) between 2014 and 2016 at the Hospital of the University of Pennsylvania. Exposed patients were those with exposure to inappropriately low-dose GCV/VGCV. Unexposed patients were those whose antiviral dosing was consistently appropriate for their creatinine clearance. We employed a multivariable Cox proportional hazard analysis to determine the impact of low-dose prophylaxis on time to CMV infection post-transplant; prophylaxis dosing was incorporated as a time-varying covariate in this survival analysis. Results 108 adults underwent CMV D+ LT during the study period. 46 (43%) experienced low prophylaxis dosing at some point during their prophylaxis course. 47 (43%) LTRs developed CMV viremia, of which 10 (9%) were still on prophylaxis. 20 (19%) LTRs developed CMV disease and 6 (6%) had ganciclovir-resistant CMV. In the multivariable Cox analysis, we found that there was not a significant association between exposure to any low-dose prophylaxis and the hazard of CMV infection (HR = 1.001, 95% CI 0.99–1.01, P = 0.75; Table 1), even among CMV seronegative recipients (D+/R−) (HR = 1.002, 95% CI 0.99–1.01, P = 0.68). When only those who received > 28 days of low-dose prophylaxis (N = 6, 6%) were evaluated, there was a trend toward an increased hazard of CMV infection (HR = 1.001, 95% CI 0.999–1.004, P = 0.18; Table 2). Conclusion CMV D+ LTR are frequently exposed to inappropriately low CMV prophylaxis dosing. This does not appear to significantly increase the risk for CMV infection, though prolonged subtherapeutic exposure merits further exploration as a risk factor for CMV outcomes in higher-risk patients. ![]()

Abstract
INTRODUCTION Left ventricular assist device (LVAD) infections are common, and the consequences of LVAD infections on orthotopic heart transplantation (OHT) outcomes are not well described. AIMS The aim of this study was to describe clinical characteristics and evaluate risk factors for developing LVAD infections, and examine outcomes of LVAD-specific infections (VSI) after OHT. METHODS We retrospectively investigated the records of 74 consecutive patients at two institutions who had undergone LVAD placement and subsequent OHT between January 2007 and December 2012. RESULTS Forty-six of 74 (62%) LVAD recipients who underwent OHT had pre-transplant infections, and 18 (24%) had LVAD-specific infection (VSI), of which 71% were caused by gram-negative organisms. Of pre-transplant non-LVAD infections, Clostridium difficile infection (CDI) was the most common (26%) followed by urinary tract infection (UTI, 16%) and pneumonia (PNA 15%). Univariate analysis comparing subjects with VSI to those without VSI showed a significant association with time spent outside the hospital prior to transplantation (median 231.8 days vs 142.2 days, P < 0.03) and total time between VAD placement and OHT (244.0 days and 150.5 days, P < 0.002). Logistic regression was performed and significant predictors for VAD-related infection were age and the presence of diabetes, with type of device as an effect modifier. Six months post-OHT survival was not significantly affected by the presence of VSI prior to transplant. There was a trend toward an association between the presence of any infection and post-transplant rejection (P < 0.09). There were 10 post-transplant deaths by 6 months. Of these deaths, 4/10 (40%) were cardiopulmonary and 6/10 (60%) were related to infections. CONCLUSIONS Advanced age and presence of diabetes were predictors of VSI, as well as type of VAD device, although device choice is likely affected by many clinical factors including age and comorbidities, as well as institution-specific preferences. VSI was not associated with a decrease in 6-month post-OHT survival. However, infections remain the major causes of death by 6 months post-transplant. Certain infections are associated with an increased risk of rejection, which merits further investigation.
