Abstract
PURPOSE Bronchopulmonary dysplasia (BPD) is the most common complication of extreme preterm birth and structural lung abnormalities are frequently found in children with BPD. To quantify lung damage in BPD, three new Hounsfield units (HU) based chest-CT scoring methods were evaluated in terms of 1) intra- and inter-observer variability, 2) correlation with the validated Perth-Rotterdam-Annotated-Grid-Morphometric-Analysis (PRAGMA)-BPD score, and 3) correlation with clinical data. METHODS Chest CT scans of children with severe BPD were performed at a median of 7 months corrected age. Hyper- and hypo-attenuated regions were quantified using PRAGMA-BPD and three new HU based scoring methods (automated, semi-automated, and manual). Intra- and inter-observer variability was measured using intraclass correlation coefficients (ICC) and Bland-Altman plots. The correlation between the 4 scoring methods and clinical data was assessed using Spearman rank correlation. RESULTS Thirty-five patients (median gestational age 26.1 weeks) were included. Intra- and inter-observer variability was excellent for hyper- and hypo-attenuation regions for the manual HU method and PRAGMA-BPD (ICCs range 0.80-0.97). ICC values for the semi-automated HU method were poorer, in particular for the inter-observer variability of hypo- (0.22-0.71) and hyper-attenuation (-0.06-0.89). The manual HU method was highly correlated with PRAGMA-BPD score for both hyper- (ρs0.92, p < 0.001) and hypo-attenuation (ρs0.79, p < 0.001), while automated and semi-automated HU methods showed poor correlation for hypo- (ρs < 0.22) and good correlation for hyper-attenuation (ρs0.72-0.74, p < 0.001). Several scores of hyperattenuation correlated with the use of inhaled bronchodilators in the first year of life; two hypoattenuation scores correlated with birth weight. CONCLUSIONS PRAGMA-BPD and the manual HU method have the best reproducibility for quantification of CT abnormalities in BPD.

Abstract
INTRODUCTION Since lung adenocarcinoma (LUAD) biopsies are usually small, it is questionable if their prognostic and predictive information is comparable to what is offered by large resection specimens. This study compares LUAD biopsies and resection specimens for their ability to provide prognostic and predictive parameters. METHODS We selected 187 biopsy specimens with stage I and II LUAD. In 123 cases, subsequent resection specimens were also available. All specimens were evaluated for growth pattern, nuclear grade, fibrosis, inflammation, and genomic alterations. Findings were compared using non-parametric testing for categorical variables. Model performance was assessed using the area under the curve for both biopsies and resection specimens, and overall (OS) and disease-free survival (DFS) was calculated. RESULTS The overall growth pattern concordance between biopsies and resections was 73.9%. The dominant growth pattern correlated with OS and DFS in resected adenocarcinomas and for high-grade growth pattern in biopsies. Multivariate analysis of biopsy specimens revealed that T2-tumors, N1-status, KRAS mutations and a lack of other driver mutations were associated with poorer survival. Model performance using clinical, histological and genetic data from biopsy specimens for predicting OS and DSF demonstrated an AUC of 0.72 and 0.69, respectively. CONCLUSIONS Our data demonstrated the prognostic relevance of a high-grade growth pattern in biopsy specimens of LUAD. Combining clinical, histological and genetic information in one model demonstrated a suboptimal performance for DFS prediction and good performance for OS prediction. However, for daily practice, more robust (bio)markers are required to predict prognosis and stratify patients for therapy and follow-up.

Abstract
BACKGROUND Dupilumab was equally effective among all racial subgroups in clinical trials, but a direct comparison in daily practice is lacking. OBJECTIVES To investigate the effectiveness of dupilumab in patients with atopic dermatitis (AD) in the Netherlands and Japan over 80 weeks of treatment. METHODS A longitudinal comparative cohort study was conducted in patients with AD who were treated with dupilumab in daily practice. We used linear mixed-effects models to determine changes over time. RESULTS We found statistically significant differences in sex, disease onset, body mass index and therapeutic history between Dutch (n = 208) and Japanese (n = 153) patients. The baseline Eczema Area and Severity Index (EASI) score was higher in Japanese patients (23·8 vs. 14·8), while baseline Patient-Reported Outcome Measures (PROMs) were higher in Dutch patients. EASI scores decreased quickly to a level indicating 'mild disease' (EASI < 7), and remained low in both countries. However, PROMs showed different trajectories with better scores in Japan. CONCLUSIONS Dupilumab showed significant, comparable and sustained improvement of EASI scores in Japanese and Dutch patients. However, we found striking differences in the effect on PROMs between the countries, with a better outcome in Japanese patients.

Abstract
BACKGROUND In HIV-infected patients, the immunogenicity of hepatitis B vaccines is impaired. In this randomised controlled study (RCT), we investigated the effect of Fendrix® versus double-dose Engerix® vaccination in previously non-responsive HIV-infected subjects. METHODS Patients included those who were HIV-infected and non-responders to a primary (single-dose hepatitis B (HBV) vaccination) and a subsequent double-dose HBV revaccination schedule. Subjects were randomised 1:1 to receive Fendrix® (t = 0, 4, 8, 24 weeks) or double-dose Engerix® (t = 0, 4, 24 weeks) vaccinations. Primary efficacy, defined as anti-HBs response ≥ 10 IU/l, was evaluated at week 28 in both study arms. RESULTS A subset of 48 patients non-responsive to HBV vaccination was selected, from a cohort of patients at our institution, who underwent HBV vaccination unsuccessfully either in a previous RCT or through standard care. The anti-HBs ≥ 10 IU/l response rate at week 28 in the Fendrix® arm and the Engerix® arm were 85.7% and 65.0%, respectively (p = 0.09). There was no significant difference between the two used vaccine types in the anti-HBs levels reached. In our institution, the overall response rate after initial standard-dose vaccination schedule and double-dose revaccination in our cohort was 75%. In this study, combining the effects of Fendrix and Engerix resulted in a 75% response rate in the 25% remaining non-responders on initial and double-dose revaccination series. This yielded an absolute 19% increase and an overall response to HBV vaccination in HIV-infected patients of around 94% in our cohort. CONCLUSION These results together, suggest that continuing HBV vaccination in non-responders to a first course of single-dose vaccine and a double-dose revaccination scheme is worth the effort. No superiority of one of the investigated hepatitis B vaccines was shown in this cohort but an appropriate number of patients needed to achieve reliable answers was not achieved.

Abstract
Background Attenuated decreases in lung function can signal the onset of acute respiratory events known as pulmonary exacerbations (PEs) in children and adolescents with cystic fibrosis (CF). Univariate joint modeling facilitates dynamic risk prediction of PE onset and accounts for measurement error of the lung function marker. However, CF is a multi-system disease and the extent to which simultaneously modeling growth and nutrition markers improves PE predictive accuracy is unknown. Furthermore, it is unclear which routinely collected clinical indicators of growth and nutrition in early life predict PE onset in CF. Methods Using a longitudinal cohort of 17,100 patients aged 6–20 years (US Cystic Fibrosis Foundation Patient Registry; 2003–2015), we fit a univariate joint model of lung-function decline and PE onset and contrasted its predictive performance with a class of multivariate joint models that included combinations of growth markers as additional submodels. Outcomes were longitudinal lung function (forced expiratory volume in 1 s of % predicted), percentiles of body mass index, weight-for-age and height-for-age and PE onset. Relevant demographic/clinical covariates were included in submodels. We implemented a univariate joint model of lung function and time-to-PE and four multivariate joint models including growth outcomes. Results All five joint models showed that declining lung function corresponded to slightly increased risk of PE onset (hazard ratio from univariate joint model: 0.97, P < 0.0001), and all had reasonable predictive accuracy (cross-validated area under the receiver-operator characteristic curve > 0.70). None of the growth markers alongside lung function as outcomes in multivariate joint modeling appeared to have an association with hazard of PE. Jointly modeling only lung function and PE onset yielded the most accurate (area under the receiver-operator characteristic curve = 0.75) and precise (narrowest interquartile range) predictions. Dynamic predictions were accurate across forecast horizons (0.5, 1 and 2 years) and precision improved with age. Conclusions Including growth markers via multivariate joint models did not yield gains in prediction performance, compared to a univariate joint model with lung function. Individualized dynamic predictions from joint modeling could enhance physician monitoring of CF disease progression by providing PE risk assessment over a patient’s clinical course.
