PML risk stratification using anti-JCV antibody index and L-selectin

2015

Background: Natalizumab treatment is associated with progressive multifocal leukoencephalopathy (PML) development. Treatment duration, prior immunosuppressant use, and JCV serostatus are currently used for risk stratification, but PML incidence stays high. Anti-JCV antibody index and L-selectin (CD62L) have been proposed as additional risk stratification parameters. Objective: This study aimed at verifying and integrating both parameters into one algorithm for risk stratification. Methods: Multicentric, international cohorts of natalizumab-treated MS patients were assessed for JCV index (1921 control patients and nine pre-PML patients) and CD62L (1410 control patients and 17 pre-PML patient…

An Internet based intervention for improving resilience and coping strategies in university students: Study protocol for a randomized controlled trial

2019

Background The literature shows a high prevalence of depression and anxiety in young people. The university represents a change in the lives of students, and is considered a stress factor. Therefore, it is particularly relevant to develop interventions specifically addressed to students and foster supportive environments and resilient communities. As students are “digital natives”, online interventions offer several potential advantages in doing this. This study aims to develop and evaluate the efficacy of an Internet-based intervention (CORE: Cultivating our Resilience), based on the Ryff model of well-being, to promote resilience and coping skills, decrease symptoms of depression and anxi…

Efficacy and cost-effectiveness of guided and unguided internet- and mobile-based indicated transdiagnostic prevention of depression and anxiety (ICa…

2019

Background Depression and anxiety are highly prevalent and often co-occur. Several studies indicate the potential of disorder-specific psychological interventions for the prevention of each of these disorders. To treat comorbidity, transdiagnostic treatment concepts seem to be a promising approach, however, evidence for transdiagnostic concepts of prevention remains inconclusive. Internet- and mobile-based interventions (IMIs) may be an effective means to deliver psychological interventions on a large scale for the prevention of common mental disorders (CMDs) such as depression and anxiety. IMIs have been shown to be effective in treating CMDs, e.g. in reducing symptoms of depression and an…

Blood group antigen A type 3 expression is a favorable prognostic factor in advanced NSCLC.

2015

Abstract Objectives Several blood group-related carbohydrate antigens are prognosis-relevant markers of tumor tissues. A type 3 (repetitive A) is a blood group antigen specific for A 1 erythrocytes. Its potential expression in tumor tissues has so far not been examined. Material and methods We have evaluated its expression in normal lung and in lung cancer using a novel antibody (A69-A/E8). For comparison an anti-A antibody specific to A types 1 and 2 was used, because its expression on lung cancer tissue has been previously reported to be of prognostic relevance. Resected tissue samples of 398 NSCLC patients were analyzed in immunohistochemistry using tissue microarrays. Results and conclu…

Assessing the costs and cost-effectiveness of ICare internet-based interventions (protocol)

2019

Background: Mental health problems are common and place a burden on the individual as well as on societal resources. Despite the existence of evidence-based treatments, access to treatment is often prevented or delayed due to insufficient health care resources. Effective internet-based self-help interventions have the potential to reduce the risk for mental health problems, to successfully bridge waiting time for face-to-face treatment and to address inequities in access. However, little is known about the cost-effectiveness of such interventions. This paper describes the study protocol for the economic evaluation of the studies that form the ICare programme of internet-based interventions …

Arsenic trioxide-based therapy of relapsed acute promyelocytic leukemia: registry results from the European LeukemiaNet

2015

In 2008, a European registry of relapsed acute promyelocytic leukemia was established by the European LeukemiaNet. Outcome data were available for 155 patients treated with arsenic trioxide in first relapse. In hematological relapse (n=104), 91% of the patients entered complete hematological remission (CR), 7% had induction death and 2% resistance, 27% developed differentiation syndrome and 39% leukocytosis, whereas no death or side effects occurred in patients treated in molecular relapse (n=40). The rate of molecular (m)CR was 74% in hematological and 62% in molecular relapse (P=0.3). All patients with extramedullary relapse (n=11) entered clinical and mCR. After 3.2 years median follow-u…

Sunlight exposure exerts immunomodulatory effects to reduce multiple sclerosis severity

2021

AbstractBackgroundMultiple sclerosis (MS) disease risk is associated with reduced sun exposure. This study assessed the relationship between measures of sun-exposure (vitamin D (vitD), latitude) and MS disease severity, the mechanisms of action, and effect-modification by medication and sun-sensitivity associated MC1R variants.MethodsTwo multi-center cohort studies (nNationMS=946, nBIONAT=991). Outcomes were the multiple sclerosis severity score (MSSS) and the number of Gd-enhancing lesion (GELs). RNAseq of four immune cell populations before and after UV-phototherapy of five MS patients.ResultsHigh serum vitD was associated with reduced MSSS (PNationMS=0.021; PBIONAT=0.007) and reduced ris…

Healthy Teens @ School: Evaluating and disseminating transdiagnostic preventive interventions for eating disorders and obesity for adolescents in sch…

2019

Background The worldwide prevalence of overweight and obesity is at alarming levels. Nearly one in three children in Europe is overweight or obese. Disordered eating and body image concerns are equally widespread and increase risk for more chronic and severe weight-related problems. Research has shown that online interventions that address both healthy weight regulation and body image can reduce risk for eating disorders and obesity simultaneously and are feasible to implement in school settings. To date, evaluation and dissemination of such programs in Europe is scant. Methods The Healthy Teens @ School study is a multi-country cluster-randomized controlled trial (RCT) comparing the effect…

The prognostic impact of PD1 and PDL1 expression in non-small cell lung cancer

2015

Introduction: To improve the prognosis of lung cancer patients, immunotherapy is expected to become a powerful therapeutic option. Several clinical studies demonstrate a positive prognostic effect of a targeted therapy against the programmed cell death receptor PD1 and its ligand PDL1 in solid tumors. For non-small lung cancer (NSCLC) however, the diagnostic, prognostic and predictive impact of these factors needs to be clarified. Materials and Methods: Immunohistochemistry was performed to evaluate the expression profile of PD1 and PDL1 in 398 NSCLC patients (median age: 66 years, 78% male sex, 45% squamous cell carcinoma (SCC) histology). Statistical analysis included Fisher9s Exact test,…
