- Introduction: The number of randomized controlled trials (RCTs) investigating the effects of exercise among cancer survivors has increased in recent years; however, participants dropping out of the trials are rarely described. The objective of the present study was to assess which combinations of participant and exercise program characteristics were associated with dropout from the exercise arms of RCTs among cancer survivors. Methods: This study used data collected in the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) study, an international database of RCTs investigating the effects of exercise among cancer survivors. Thirty-four exercise trials, with a total of 2467 patients without metastatic disease randomized to an exercise arm were included. Harmonized studies included a pre and a posttest, and participants were classified as dropouts when missing all assessments at the post-intervention test. Subgroups were identified with a conditional inference tree. Results: Overall, 9.6% of the participants dropped out. Five subgroups were identified in the conditional inference tree based on four significant associations with dropout. Most dropout was observed for participants with BMI >28.4 kg/m2, performing supervised resistance or unsupervised mixed exercise (19.8% dropout) or had low-medium education and performed aerobic or supervised mixed exercise (13.5%). The lowest dropout was found for participants with BMI >28.4 kg/m2 and high education performing aerobic or supervised mixed exercise (5.1%), and participants with BMI ≤28.4 kg/m2 exercising during (5.2%) or post (9.5%) treatment. Conclusions: There are several systematic differences between cancer survivors completing and dropping out from exercise trials, possibly affecting the external validity of exercise effects. © 2024 The Authors.

- In patients with interstitial lung disease (ILD) complicating classical or amyopathic idiopathic inflammatory myopathy (IIM), lung transplantation outcomes might be affected by the disease and treatments. Here, our objective was to assess survival and prognostic factors in lung transplant recipients with IIM-ILD. We retrospectively reviewed data for 64 patients who underwent lung transplantation between 2009 and 2021 at 19 European centers. Patient survival was the primary outcome. At transplantation, the median age was 53 [46–59] years, 35 (55%) patients were male, 31 (48%) had classical IIM, 25 (39%) had rapidly progressive ILD, and 21 (33%) were in a high-priority transplant allocation program. Survival rates after 1, 3, and 5 years were 78%, 73%, and 70%, respectively. During follow-up (median, 33 [7–63] months), 23% of patients developed chronic lung allograft dysfunction. Compared to amyopathic IIM, classical IIM was characterized by longer disease duration, higher-intensity immunosuppression before transplantation, and significantly worse posttransplantation survival. Five (8%) patients had a clinical IIM relapse, with mild manifestations. No patient experienced ILD recurrence in the allograft. Posttransplantation survival in IIM-ILD was similar to that in international all-cause-transplantation registries. The main factor associated with worse survival was a history of muscle involvement (classical IIM). In lung transplant recipients with idiopathic inflammatory myopathy, survival was similar to that in all-cause transplantation and was worse in patients with muscle involvement compared to those with the amyopathic disease. © 2022 The Authors.

Journal article (peer-reviewed)abstract
- Study question In patients with sarcoidosis, past and ongoing immunosuppressive regimens, recurrent disease in the transplant and extrapulmonary involvement may affect outcomes of lung transplantation. We asked whether sarcoidosis lung phenotypes can be differentiated and, if so, how they relate to outcomes in patients with pulmonary sarcoidosis treated by lung transplantation. Patients and methods We retrospectively reviewed data from 112 patients who met international diagnostic criteria for sarcoidosis and underwent lung or heart-lung transplantation between 2006 and 2019 at 16 European centres. Results Patient survival was the main outcome measure. At transplantation, median (interaquartile range (IQR)) age was 52 (46-59) years; 71 (64%) were male. Lung phenotypes were individualised as follows: 1) extended fibrosis only; 2) airflow obstruction; 3) severe pulmonary hypertension (sPH) and airflow obstruction; 4) sPH, airflow obstruction and fibrosis; 5) sPH and fibrosis; 6) airflow obstruction and fibrosis; 7) sPH; and 8) none of these criteria, in 17%, 16%, 17%, 14%, 11%, 9%, 5% and 11% of patients, respectively. Post-transplant survival rates after 1, 3, and 5 years were 86%, 76% and 69%, respectively. During follow-up (median (IQR) 46 (16-89) months), 31% of patients developed chronic lung allograft dysfunction. Age and extended lung fibrosis were associated with increased mortality. Pulmonary fibrosis predominating peripherally was associated with short-term complications. Answer to the study question Post-transplant survival in patients with pulmonary sarcoidosis was similar to that in patients with other indications for lung transplantation. The main factors associated with worse survival were older age and extensive pre-operative lung fibrosis.

Research review (peer-reviewed)abstract
- PURPOSE: This study evaluated the effects of coping skills training (CST) on symptoms of depression and anxiety in cancer patients, and investigated moderators of the effects.METHODS: Overall effects and intervention-related moderators were studied in meta-analyses of pooled aggregate data from 38 randomized controlled trials (RCTs). Patient-related moderators were examined using linear mixed-effect models with interaction tests on pooled individual patient data (n = 1953) from 15 of the RCTs.RESULTS: CST had a statistically significant but small effect on depression (g = -0.31,95% confidence interval (CI) = -0.40;-0.22) and anxiety (g = -0.32,95%CI = -0.41;-0.24) symptoms. Effects on depression symptoms were significantly larger for interventions delivered face-to-face (p = .003), led by a psychologist (p = .02) and targeted to patients with psychological distress (p = .002). Significantly larger reductions in anxiety symptoms were found in younger patients (pinteraction < 0.025), with the largest reductions in patients <50 years (β = -0.31,95%CI = -0.44;-0.18) and no significant effects in patients ≥70 years. Effects of CST on depression (β = -0.16,95%CI = -0.25;-0.07) and anxiety (β = -0.24,95%CI = -0.33;-0.14) symptoms were significant in patients who received chemotherapy but not in patients who did not (pinteraction < 0.05).CONCLUSIONS: CST significantly reduced symptoms of depression and anxiety in cancer patients, and particularly when delivered face-to-face, provided by a psychologist, targeted to patients with psychological distress, and given to patients who were younger and received chemotherapy.

Synchronization of mothers and offspring promotes tolerance and limits allergy
- 2020

Journal article (peer-reviewed)abstract
- Allergic disorders, characterized by Th2 immune responses to environmental substances, are increasingly common in children in Western societies. Multiple studies indicate that breastfeeding, early complementary introduction of food allergens, and antibiotic avoidance in the first year of life reduces allergic outcomes in at-risk children. Why the benefit of these practices is restricted to early life is largely unknown. We identified a preweaning interval during which dietary antigens are assimilated by the colonic immune system. This interval is under maternal control via temporal changes in breast milk, coincides with an influx of naive T cells into the colon, and is followed by the development of a long-lived population of colonic peripherally derived Tregs (pTregs) that can be specific for dietary antigens encountered during this interval. Desynchronization of mothers and offspring produced durable deficits in these pTregs, impaired tolerance to dietary antigens introduced during and after this preweaning interval, and resulted in spontaneous Th2 responses. These effects could be rescued by pTregs from the periweaning colon or by Tregs generated in vitro using periweaning colonic antigen-presenting cells. These findings demonstrate that mothers and their offspring are synchronized for the development of a balanced immune system.

Journal article (peer-reviewed)abstract
- PURPOSE: In the context of sarcoidosis, lung transplantation is often performed in patients with irreversible advanced lung disease unresponsive to medical therapy. The clinical phenotypes and posttransplant survival remain unclear, due primarily to the recurring nature of the disease and extrapulmonary involvement. The objective of this study in a large multicenter European cohort was to describe the clinical characteristics and outcomes of patients with pulmonary sarcoidosis treated by lung transplantation. METHODS: We retrospectively reviewed the data of 147 patients with pulmonary sarcoidosis who underwent lung or heart-lung transplantation between 1990 and 2019 at 15 European centers. Inclusion criteria were sarcoidosis meeting international diagnostic criteria and availability of data from pretransplantation right heart catheterization, lung function testing, and chest computed tomography (CT) staged using a standardized system. RESULTS: At transplantation, mean age was 50±8 years, 62% were male, and 20% had extrapulmonary manifestations. Mean values before transplantation were as follows: FVC (%pred), 46±17%; FEV1 (%pred), 38±19; FVC/FEV1 (%), 55±32; DLCO (%pred), 31±13; mPAP (mmHg), 36±13; PCWP (mmHg), 10±5; cardiac index (L/min/m²), 3.0±0.8; and pulmonary vascular resistance (dyn·s·cm-5), 480±340; furthermore, 60% of patients had severe pulmonary hypertension. Posttransplant survival rates after 1, 3, and 5 years were 85%, 69%, and 63%, respectively. During the median [range] follow-up of 43 [17-79] months, 38% of patients developed chronic lung allograft dysfunction. Factors significantly associated with outcomes were high emergency transplantation, era of transplantation, preoperative extrapulmonary sarcoidosis, and extent of fibrosis by CT. CONCLUSION: Posttransplant survival rates and freedom from chronic lung allograft dysfunction in patients with pulmonary sarcoidosis were similar to those in patients with other reasons for lung transplantation. Factors associated with worse outcomes were high emergency transplantation, earlier transplantation era, preoperative extrapulmonary sarcoidosis, and greater burden of fibrosis by CT.

Genetic contribution to the divergence in type 1 diabetes risk between children from the general population and children from affected families
- 2019

In: Diabetes. - : American Diabetes Association. - 0012-1797 .- 1939-327X. ; 68:4, s. 847-857

Journal article (peer-reviewed)abstract
- The risk for autoimmunity and subsequently type 1 diabetes is 10-fold higher in children with a first-degree family history of type 1 diabetes (FDR children) than in children in the general population (GP children). We analyzed children with high-risk HLA genotypes (n = 4,573) in the longitudinal TEDDY birth cohort to determine how much of the divergent risk is attributable to genetic enrichment in affected families. Enrichment for susceptible genotypes of multiple type 1 diabetes–associated genes and a novel risk gene, BTNL2, was identified in FDR children compared with GP children. After correction for genetic enrichment, the risks in the FDR and GP children converged but were not identical for multiple islet autoantibodies (hazard ratio [HR] 2.26 [95% CI 1.6–3.02]) and for diabetes (HR 2.92 [95% CI 2.05–4.16]). Convergence varied depending upon the degree of genetic susceptibility. Risks were similar in the highest genetic susceptibility group for multiple islet autoantibodies (14.3% vs .12.7%) and diabetes (4.8% vs. 4.1%) and were up to 5.8-fold divergent for children in the lowest genetic susceptibility group, decreasing incrementally in GP children but not in FDR children. These findings suggest that additional factors enriched within affected families preferentially increase the risk of autoimmunity and type 1 diabetes in lower genetic susceptibility strata.

Lung transplantation after allogeneic stem cell transplantation: a pan-European experience
- 2018
-
In: European Respiratory Journal. - : European Respiratory Society (ERS). - 0903-1936 .- 1399-3003. ; 51:2
-
Journal article (peer-reviewed)abstract
- Late-onset noninfectious pulmonary complications (LONIPCs) affect 6% of allogeneic stem cell transplantation (SCT) recipients within 5 years, conferring subsequent 5-year survival of 50%. Lung transplantation is rarely performed in this setting due to concomitant extrapulmonary morbidity, excessive immunosuppression and concerns about recurring malignancy being considered contraindications. This study assesses survival in highly selected patients undergoing lung transplantation for LONIPCs after SCT. SCT patients undergoing lung transplantation at 20 European centres between 1996 and 2014 were included. Clinical data pre- and post-lung transplantation were reviewed. Propensity score-matched controls were generated from the Eurotransplant and Scandiatransplant registries. Kaplan-Meier survival analysis and Cox proportional hazard regression models evaluating predictors of graft loss were performed. Graft survival at 1, 3 and 5 years of 84%, 72% and 67%, respectively, among the 105 SCT patients proved comparable to controls (p=0.75). Sepsis accounted for 15 out of 37 deaths (41%), with prior mechanical ventilation (HR 6.9, 95% CI 1.0-46.7; p<0.001) the leading risk factor. No SCT-specific risk factors were identified. Recurring malignancy occurred in four patients (4%). Lung transplantation <2 years post-SCT increased all-cause 1-year mortality (HR 7.5, 95% CI 2.3-23.8; p=0.001). Lung transplantation outcomes following SCT were comparable to other end-stage diseases. Lung transplantation should be considered feasible in selected candidates. No SCT-specific factors influencing outcome were identified within this carefully selected patient cohort.

Lung transplantation for scleroderma lung disease: An international, multicenter, observational cohort study
- 2018
-
In: Journal of Heart and Lung Transplantation. - : Elsevier BV. - 1053-2498. ; 37:7, s. 903-911
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Due to its multisystemic nature, scleroderma is considered a relative contraindication to lung transplantation at many centers. However, recent studies suggest similar post-transplant outcomes in patients with scleroderma compared to those with other causes of interstitial lung disease (ILD). Furthermore, it remains unknown whether scleroderma-associated pulmonary arterial hypertension (PAH) influences post-transplant outcomes. Our objective in this study was to assess the indications, survival, and prognostic factors of lung or heart lung transplantation for scleroderma lung disease. METHODS: We retrospectively reviewed the data of 90 patients with scleroderma who underwent lung or heart lung transplantation between 1993 and 2016 at 14 European centers. International criteria were used to diagnose scleroderma. Pulmonary hypertension (PH) was diagnosed during right heart catheterization based on international guidelines. RESULTS: Survival rates after 1, 3, and 5 years were 81%, 68%, and 61%, respectively. By univariate analysis, borderline-significant associations with poorer survival were found for female gender (hazard ratio 2.11; 95% confidence interval [CI] 0.99 to 4.50; p = 0.05) and PAH as the reason for transplantation (hazard ratio 1.90; 95% CI 0.96 to 3.92; p = 0.06). When both these factors were present in combination, the risk of death was 3-fold that in males without PAH. The clinical and histologic presentation resembled veno-occlusive disease in 75% of patients with PAH. CONCLUSIONS: Post-transplant survival rates and freedom from chronic lung allograft dysfunction in patients with scleroderma were similar to those in patients with other reasons for lung transplantation. Female sex and PAH in combination was associated with lower survival. (C) 2018 International Society for Heart and Lung Transplantation. All rights reserved.

Minimization of Childhood Maltreatment Is Common and Consequential: Results from a Large, Multinational Sample Using the Childhood Trauma Questionnaire
- 2016
-
In: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 11:1
-
Journal article (peer-reviewed)abstract
- Childhood maltreatment has diverse, lifelong impact on morbidity and mortality. The Childhood Trauma Questionnaire (CTQ) is one of the most commonly used scales to assess and quantify these experiences and their impact. Curiously, despite very widespread use of the CTQ, scores on its Minimization-Denial (MD) subscale-originally designed to assess a positive response bias-are rarely reported. Hence, little is known about this measure. If response biases are either common or consequential, current practices of ignoring the MD scale deserve revision. Therewith, we designed a study to investigate 3 aspects of minimization, as defined by the CTQ's MD scale: 1) its prevalence; 2) its latent structure; and finally 3) whether minimization moderates the CTQ's discriminative validity in terms of distinguishing between psychiatric patients and community volunteers. Archival, item-level CTQ data from 24 multinational samples were combined for a total of 19,652 participants. Analyses indicated: 1) minimization is common; 2) minimization functions as a continuous construct; and 3) high MD scores attenuate the ability of the CTQ to distinguish between psychiatric patients and community volunteers. Overall, results suggest that a minimizing response bias-as detected by the MD subscale-has a small but significant moderating effect on the CTQ's discriminative validity. Results also may suggest that some prior analyses of maltreatment rates or the effects of early maltreatment that have used the CTQ may have underestimated its incidence and impact. We caution researchers and clinicians about the widespread practice of using the CTQ without the MD or collecting MD data but failing to assess and control for its effects on outcomes or dependent variables.
