Background: We examined the association of adult lung transplant candidates’ self-reported affect with transplant-related outcomes, evaluating whether a positive (vs negative) frame of mind might be protective. Method: Consenting waitlisted candidates from 6 centers completed the questionnaires including the Positive and Negative Affect Schedule annually and posttransplant. Univariate logistic regression analysis was performed to determine the association of baseline affect with outcomes of death or delisting. Models were subsequently adjusted for age, marital status, and education. Results: Questionnaires were completed by 169 candidates (77.9% participation). Mean positive affect, negative affect, and positive-to-negative affect ratio (positivity ratio) were similar to expected norms. The scores of the questionnaire did not change significantly over time. Fifteen (8.9%) waitlisted participants died. Candidates who died while waiting had lower positivity ratios compared to those who survived (1.82 vs 2.45; P = .02). A more negative affect was associated with increased death on the waiting list (adjusted odds ratio [OR] 1.10; P = .021). Conversely, a higher positivity ratio was associated with decreased death while waiting (adjusted OR: 0.45; P = .027). Conclusion: Negative affect may represent a novel risk factor for death on the waitlist. Enhancing positive affect may represent a useful target for psychological optimization in lung transplant candidates.

Abstract Declining a donor when there is a reasonable possibility that the abnormality on chest imaging could be benign carries the risk of losing out on potentially usable lungs in an already parched landscape of donor organ availability. Cautiously aggressive attitudes to acceptance of borderline donors can help bridge the significant discrepancy that exists between the demand and availability of donor organs. Herein, we present a case highlighting successful bilateral lung transplantation from a relatively imperfect donor.

A true left middle lobe (lingular lobe) is very rare, but accessory fissures can be unexpectedly found at transplant. Pre-transplant knowledge of accessory lobes and accessory fissures aids in preparation, transplantation, postoperative assessment, and long-term care planning; however, fissures and accessory lobes can be overlooked by radiologists during routine evaluation of images. Here, we describe the first left lung with three anatomical lobes that was successfully transplanted into a 63-year-old patient with idiopathic pulmonary fibrosis. This anatomical variation did not change our surgical plan or technique, but surgeons should be aware of this possibility, especially when planning postoperative care.

Goals: To assess the effect of unilateral versus bilateral lung transplantation (LTx) on esophageal motility and gastroesophageal reflux, and the association with the development of obstructive chronic lung allograft dysfunction (o-CLAD). Background: We have shown that esophagogastric junction outflow obstruction, incomplete bolus transit, and proximal reflux are all independent risk factors for the development of chronic allograft failure. However, it remains unclear whether these factors are influenced by the type of surgery and how this relates to allograft failure. Study: Patients post-LTx (n=48, 24 female; aged 20 to 73 y) completed high-resolution impedance manometry and 24-hour pH/impedance. Results: Patients who had undergone unilateral LTx were more likely to exhibit esophagogastric junction outflow obstruction (47% vs. 18%; P=0.046) and less likely to exhibit hypocontractility (0% vs. 21%; P=0.058) than those who had undergone bilateral LTx. Although the proportion of patients exhibiting gastroesophageal reflux was no different between groups (33% vs. 39%; P=0.505), those undergoing bilateral LTx were more likely to exhibit proximal reflux (8% vs. 37%; P=0.067). Univariate Cox proportion hazards regression analysis did not show a difference between unilateral versus bilateral LTx in the development of o-CLAD (hazard ratio=1.17; 95% confidence interval, 0.48-2.85; P=0.723). Conclusion: The type of LTx performed seems to lead to different risk factors for the development of o-CLAD. Physicians should be aware of these differences, as they may need to be taken into account when managing patient’s post-LTx.

Familial interstitial lung disease (ILD) is defined as presence of ILD in 2 or more family members. Surfactant protein C (SFTPC) gene mutations are rare, but well-known cause of familial ILD. We reported a 20-year-old male, who was referred for lung transplantation. He was symptomatic at age 3 and underwent surgical lung biopsy at age 6, which revealed a nonspecific interstitial pneumonia (NSIP) pattern. Genetic workup revealed a novel SFTPC mutation in the first intron with a C to A transversion. At age 21, he underwent bilateral lung transplantation. Explanted lung histology suggested NSIP. In addition there was pulmonary neuroendocrine cell (PNEC) hyperplasia and carcinoid tumorlets. His mother had undergone lung transplantation several years earlier, and her explanted lung showed similar pathology. SFTPC mutations are inherited in an autosomal dominant pattern. Various types of ILD have been associated with SFTPC mutation including NSIP, usual interstitial pneumonia (UIP), and desquamative interstitial pneumonia (DIP). PNEC hyperplasia has been described to occur in association with lung inflammation but has not been previously described with familial ILD associated with SFTPC mutation.
