Abstract
BACKGROUND In the general population, prior infection with SARS-CoV-2 reduces the risk of severe COVID-19; however, studies in lung transplant recipients (LTRs) are lacking. We sought to describe the clinical course of COVID-19 recurrence and compare outcomes between the first and second episodes of COVID-19 in LTRs. METHODS We conducted a retrospective, single-center cohort study of LTRs with COVID-19 between January 1, 2022, and September 30, 2022, during the Omicron wave. We compared the clinical course of a second episode of COVID-19 to that of the patients' own first episode and to that of LTRs who developed a first episode during the study period. RESULTS During the study period, we identified 24 LTRs with COVID-19 recurrence and another 75 LTRs with a first episode of COVID-19. LTRs who survived the initial episode of COVID-19 had a similar disease course with recurrence, with a trend toward reduced hospitalization (10 (41.6%) vs. 4 (16.7%), p = .114). Furthermore, compared to LTRs with a primary infection during the Omicron wave, those with a reinfection had a non-statistically significant trend toward reduced hospitalizations (aOR .391, 95% CI [.115-1.321], p = .131), shorter lengths-of-stay (median, 4 vs. 9 days, p = .181), and reduced intensive care unit admissions, intubations, and COVID-19-related mortality. CONCLUSIONS LTRs who survive the first episode of COVID-19 are likely to have a similar clinical course with recurrent episodes. Although recurrent COVID-19 may be milder, larger, well-powered studies are needed to confirm this observation. Ongoing precautions are warranted.

Abstract
The respiratory tract of lung transplant recipients (LTR) is likely to be colonized with non-fermentative Gram-negative rods. As a consequence of the improvements in molecular sequencing and taxonomy, an increasing number of bacterial species have been described. We performed a review of the literature of bacterial infections in LTR involving non-fermentative Gram-negative rods with exclusion of Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Achromobacter spp. and Burkholderia spp. Overall, non-fermenting GNR were recovered from 17 LTR involving the following genera: Acetobacter, Bordetella, Chryseobacterium, Elizabethkinga, Inquilinus, and Pandoraea. We then discuss the issues raised by these bacteria, including detection and identification, antimicrobial resistance, pathogenesis, and cross-transmission.

Abstract
Inquilinus limosus is an environmental bacterium associated with respiratory tract colonization in cystic fibrosis patients. We report a case of I. limosus bacteremia in a patient in France who received a lung transplant and experienced chronic graft dysfunction and SARS-CoV-2 infection. This case suggests I. limosus displays virulence factors associated with invasion.

Abstract
Aim: Meropenem-vaborbactam and delafloxacin activities were not assessed against Achromobacter spp. (Achr), Burkholderia cepacia complex (Bcc) and Stenotrophomonas maltophilia (Smal). Methodology: A total of 106 Achr, 57 Bcc and 100 Smal were tested with gradient diffusion test of meropenem-vaborbactam, delafloxacin and comparators. Results: Meropenem-vaborbactam MIC50 were 4 μg/ml for Achr, 1 μg/ml for B. cepacia, 2 μg/ml for B. cenocepacia and B. multivorans, and 32 μg/ml for Smal. Delafloxacin MIC50 were 4 μg/ml for Achr, 0.25 μg/ml for B. cepacia and B. multivorans, 2 μg/ml for B. cenocepacia, and 0.5 μg/m for Smal. meropenem-vaborbactam MICs were fourfold lower than meropenem for 28.3% Achr, 77.2% B. cepacia, 53.8% B. cenocepacia and 77.2% B. multivorans. Conclusion: Meropenem-vaborbactam and delafloxacin are in vitro active against Bcc and Achr.

Abstract
The efficacy of pre-emptive therapy in the prevention of cytomegalovirus (CMV) disease and the potential association of CMV infection with the occurrence of chronic lung allograft dysfunction (CLAD) was evaluated in 129 lung transplant recipients receiving pre-emptive therapy based on pp65-antigenemia or CMV-DNA in the blood and in the bronchoalveolar lavage. Seventy-one (55%) patients received pre-emptive ganciclovir/valganciclovir (GCV/VGCV) for CMV infection for a median of 28 (9-191) days. Possible CMV disease occurred in six (5%) patients and was healed after the GCV/VGCV therapy. The cumulative incidence of CLAD was 38% and 54% at 5 and 10 years. Acute rejection and CMV load in the blood (but not in the lung) were independent predictors of the occurrence of CLAD. Pre-emptive therapy is highly effective in preventing CMV disease in lung recipients and does not induce a superior incidence of CLAD compared to what reported for other cohorts of patients who received an extended antiviral prophylaxis.

Abstract
Transplant recipients have significant psychosocial stressors due to unique posttransplant sequela that results in an increased incidence of psychopathology. Posttransplant psychological interventions, especially in lung transplant recipients, are understudied, as the focus of prior research has emphasized pretransplant interventions. However, posttransplant psychological stability affects medical outcomes. The importance of posttransplant psychological intervention is highlighted. Recommendations exist which call for attention to specific psychological domains in the posttransplant recovery period and highlight the impact of psychological rehabilitation on overall wellness and success in recovery. A novel psychological rehabilitation intervention is outlined as a response to posttransplant intervention recommendations to demonstrate implementation.

Abstract
BACKGROUND Invasive aspergillosis (IA) is a frequent complication in lung transplant recipients (LTRs). Clinical risk factors for IA have not been fully characterized, especially in the era of extensive anti-fungal prophylaxis. The primary objective of this study was to evaluate the clinical risk factors associated with IA in LTRs. The secondary objective was to assess the mortality in LTRs who had at least 1 episode of IA compared with LTRs who never had experienced IA. METHODS We conducted an international, multicenter, retrospective cohort study of 900 consecutive adults who received lung transplants between 2005 and 2008 with 4years of follow-up. Risk factors associated with IA were identified using univariate and multiple regression Cox proportional hazards models. RESULTS Anti-fungal prophylaxis was administered to 61.7% (555 of 900) of patients, and 79 patients developed 115 episodes of IA. The rate to development of the first episode was 29.6 per 1,000 person-years. Aspergillus fumigatus was the most common species isolated (63% [72 of 115 episodes]). Through multivariate analysis, significant risk factors identified for IA development were single lung transplant (hazard ratio, 1.84; 95% confidence interval, 1.09-3.10; p = 0.02,) and colonization with Aspergillus at 1 year post-transplantation (hazard ratio, 2.11; 95% confidence interval, 1.28-3.49; p = 0.003,). Cystic fibrosis, pre-transplant colonization with Aspergillus spp, and use of anti-fungal prophylaxis were not significantly associated with the development of IA. Time-dependent analysis showed IA was associated with higher mortality rates. CONCLUSION Incidence of IA remains high in LTRs. Single-lung transplant and airway colonization with Aspergillus spp. within 1 year post-transplant were significantly associated with IA.

Abstract
The ominous prognosis of cancer patients with or without neutropenia in need of critical care has led to reservations with regard to admission of cancer patients to the ICU. However, significant improvements in ICU and in-hospital survival of cancer patients in ICU have been demonstrated in studies in recent years [1–4]. Risk factors for mortality have shifted from those related to the underlying condition to those related to the severity of acute illness similar to other critically-ill patients. Neutropenia per se and the underlying malignancy (solid and hematological) do not have an impact on the outcome of patients in ICU. Recent chemotherapy is associated rather with improved survival [3, 5–7], while organ dysfunction, severity of disease scores, need for vasopressor treatment, need for mechanical ventilation immediately or after noninvasive ventilation, no definite diagnosis and a non-infectious diagnosis are associated with mortality [1–3, 8]. Invasive aspergillosis is also associated with very high mortality rates in ICU (see below). In several studies, admission to ICU in the early stages of sepsis or other acute event was associated with better survival than admission later, after development of organ dysfunction. Performance status is perhaps the most important and only variable relating to the underlying condition that is correlated with ICU death. The prognosis remains guarded for certain cancer patients, including patients after allogeneic hematopoietic stem cell transplantation (HSCT) with active uncontrolled graft versus host disease, those with relapse of the primary disease after allogeneic HSCT and special cases of solid cancer including pulmonary carcinomatous lymphangitis and carcinomatous meningitis with coma [9].
