Background: In the randomized Asian REGATTA trial, no survival benefit was shown for additional gastrectomy over chemotherapy alone in patients with advanced gastric cancer with a single incurable factor, thereby discouraging surgery for these patients. The purpose of this study was to evaluate treatment strategies for patients with metastatic gastric cancer in daily practice in five European countries, along with relative survival in each country.

Methods: Nationwide population-based data from Belgium, Denmark, the Netherlands, Norway and Sweden were combined.

Background: Sexual dysfunction is prevalent in women with Mayer-Rokitansky-Küster-Hauser syndrome after the creation of a neovagina. Insight into the physiologic response of the neovagina during sexual arousal is lacking, although this would help in the understanding of sexual function of these patients. The physiologic sexual response of the vagina can be measured objectively by vaginal photoplethysmography to assess vaginal blood flow.

Background: The effect of in vitro fertilisation (IVF) on breast cancer risk for BRCA1/2 mutation carriers is rarely examined. As carriers may increasingly undergo IVF as part of preimplantation genetic diagnosis (PGD), we examined the impact of ovarian stimulation for IVF on breast cancer risk in BRCA1/2 mutation carriers.

Methods: The study population consisted of 1550 BRCA1 and 964 BRCA2 mutation carriers, derived from the nationwide HEBON study and the nationwide PGD registry.

In patients with Long-QT Syndrome (LQTS), mechanical abnormalities have been described. Recognition of these abnormalities could potentially be used in the diagnosis of LQTS, especially in the foetus where an ECG is not available and DNA-analysis is invasive. We aimed to develop and validate a marker for these mechanical abnormalities in children and to test its feasibility in foetuses as a proof of principle.

Background: Ileostomy construction is a common procedure but can be associated with morbidity. The stoma is commonly secured to the skin using transcutaneous sutures. It is hypothesized that intracutaneous sutures result in a tighter adherence of the peristomal skin to the stoma plate to prevent faecal leakage.

Enteroviruses (EV) can cause severe neurological and respiratory infections, and occasionally lead to devastating outbreaks as previously demonstrated with EV-A71 and EV-D68 in Europe. However, these infections are still often underdiagnosed and EV typing data is not currently collected at European level. In order to improve EV diagnostics, collate data on severe EV infections and monitor the circulation of EV types, we have established European non-polio enterovirus network (ENPEN).

High intensity training in obesity: a Meta-analysis.

Obes Sci Pract

September 2017

Department of Pulmonology Franciscus Gasthuis Rotterdam The Netherlands.

Introduction: High Intensity training (HIT) is a time-effective alternative to traditional exercise programs in adults with obesity, but the superiority in terms of improving cardiopulmonary fitness and weight loss has not been demonstrated.

Objective: to determine the effectiveness of HIT on cardiopulmonary fitness and body composition in adults with obesity compared to traditional (high volume continuous) exercise.

Methods: A systematic search of the main health science databases was conducted for randomized controlled trials comparing HIT with traditional forms of exercise in people with obesity.

EORTC 21081 was a randomized phase III study of observation alone versus lenalidomide maintenance (25 mg po for 21 days) after debulking therapy in patients with advanced-stage cutaneous T-cell lymphomas (CTCLs). The aim was to investigate whether maintenance treatment with lenalidomide prolonged response after debulking in patients who had not been previously treated with intravenous chemotherapy. A total of 26 centres from 10 different European countries registered 30 patients with advanced CTCL.

Background: In congenital long-QT syndrome, age, sex, and genotype have been associated with cardiac events, but their effect on the trend in QTc interval has never been established. We, therefore, aimed to assess the effect of age and sex on the QTc interval in children and adolescents with type 1 (LQT1) and type 2 (LQT2) long-QT syndrome.

Methods And Results: QTc intervals of 12-lead resting electrocardiograms were determined, and trends over time were analyzed using a linear mixed-effects model.

Aim: Morbidity in patients with an ostomy is high. A new care pathway, including perioperative home visits by enterostomal therapists, was studied to assess whether more elaborate education and closer guidance could reduce stoma-related complications and improve quality of life (QoL), at acceptable cost.

Method: Patients requiring an ileostomy or colostomy, for any inflammatory or malignant bowel disease, were included in a 15-centre cluster-randomized 'stepped-wedge' study.

Objectives: The distribution of pathology in neurodegenerative disease can be predicted by the organizational characteristics of white matter in healthy brains. However, we have very little evidence for the impact these pathological changes have on brain function. Understanding any such link between structure and function is critical for understanding how underlying brain pathology influences the progressive behavioral changes associated with neurodegeneration.

Deficits in motor functioning are one of the hallmarks of Huntington's disease (HD), a genetically caused neurodegenerative disorder. We applied functional magnetic resonance imaging (fMRI) and dynamic causal modeling (DCM) to assess changes that occur with disease progression in the neural circuitry of key areas associated with executive and cognitive aspects of motor control. Seventy-seven healthy controls, 62 pre-symptomatic HD gene carriers (preHD), and 16 patients with manifest HD symptoms (earlyHD) performed a motor finger-tapping fMRI task with systematically varying speed and complexity.

ICA-based artifact removal diminishes scan site differences in multi-center resting-state fMRI.

Front Neurosci

November 2015

FMRIB, Nuffield Department of Clinical Neurosciences, Oxford Centre for Functional Magnetic Resonance Imaging of the Brain, University of Oxford Oxford, UK ; Department of Psychiatry, University of Oxford Oxford, UK.

Resting-state fMRI (R-fMRI) has shown considerable promise in providing potential biomarkers for diagnosis, prognosis and drug response across a range of diseases. Incorporating R-fMRI into multi-center studies is becoming increasingly popular, imposing technical challenges on data acquisition and analysis, as fMRI data is particularly sensitive to structured noise resulting from hardware, software, and environmental differences. Here, we investigated whether a novel clean up tool for structured noise was capable of reducing center-related R-fMRI differences between healthy subjects.
