BACKGROUND AND PURPOSE: Cerebral small vessel disease (SVD) is a frequent pathology in aging and contributor to the development of dementia. Plasma Aβ (amyloid β) levels may be useful as early biomarker, but the role of plasma Aβ in SVD remains to be elucidated. We investigated the association of plasma Aβ levels with severity and progression of SVD markers. METHODS: We studied 487 participants from the RUN DMC study (Radboud University Nijmegen Diffusion Tensor and Magnetic Resonance Imaging Cohort) of whom 258 participants underwent 3 MRI assessments during 9 years...

This paper explains a conservative, pragmatic and minimally invasive intervention concept for the treatment of severe tooth wear patients based on the Radboud Tooth Wear Project in the Netherlands. Guidelines and flowcharts for management of severe tooth wear patients and rehabilitation in increased vertical dimension of occlusion are presented. We concluded that: (a) Restorative treatment is not always indicated, even for patients with severe tooth wear. (b) If the patient has no complaints, counselling and monitoring is probably the best option...

OBJECTIVES: Reaching a certain age, juvenile idiopathic arthritis (JIA) patients in paediatric care are transferred to adult care. An increased disease activity after transfer and increased dropout has been suggested, however, evidence is scarce. Our aim is to determine whether the process of transition is associated with increased disease-activity and dropout, and to identify associated factors. METHODS: During a 3-year prospective transition cohort study, paediatric patients (14-17yrs) were transferred to adult care...

INTRODUCTION: Current guidelines for clinical biobanking have a strong focus on obtaining, handling, and storage of biospecimens. However, to allow for research tying biomarker analysis to clinical decision making, there should be more focus on collection of data on donor characteristics. Therefore, our aim was to develop a stepwise procedure to define a framework as a tool to help start the data collection process in clinical biobanking. MATERIALS AND METHODS: The Radboud Biobank (RB) is a central clinical biobanking facility designed in accordance with the standards set by the Parelsnoer Institute, a Dutch national biobank originally initiated with eight different disease cohorts...

BACKGROUND: Immunopathology contributes to the high mortality of tuberculous meningitis, but the biological pathways involved are mostly unknown. We aimed to compare cerebrospinal fluid (CSF) and serum metabolomes of patients with tuberculous meningitis with that of controls without tuberculous meningitis, and assess the link between metabolite concentrations and mortality. METHODS: In this observational cohort study at the Hasan Sadikin Hospital (Bandung, Indonesia) we measured 425 metabolites using liquid chromatography-mass spectrometry in CSF and serum from 33 HIV-negative Indonesian patients with confirmed or probable tuberculous meningitis and 22 control participants with complete clinical data between March 12, 2009, and Oct 27, 2013...

Due to security, access, and programmatic challenges in areas of Pakistan and Afghanistan, both countries continue to sustain indigenous wild poliovirus (WPV) transmission and threaten the success of global polio eradication and oral poliovirus vaccine (OPV) cessation. We fitted an existing differential-equation-based poliovirus transmission and OPV evolution model to Pakistan and Afghanistan using four subpopulations to characterize the well-vaccinated and undervaccinated subpopulations in each country. We explored retrospective and prospective scenarios for using inactivated poliovirus vaccine (IPV) in routine immunization or supplemental immunization activities (SIAs)...

OBJECTIVE: High fear of cancer recurrence (FCR) is a frequently reported problem among cancer patients. Previous research has shown that younger age is associated with higher levels of FCR. However, little attention has been given to date about how FCR manifests itself among adolescent and young adult (AYA) cancer patients. This study explores the prevalence, correlates of high FCR, and its association with HRQoL in cancer patients in their late adolescence or young adulthood. METHODS: Seventy-three AYA cancer patients, aged 18-35 years at diagnosis, consulted the AYA team of the Radboud University Medical Center completed questionnaires including the Cancer Worry Scale (CWS), Quality of Life-Cancer Survivors (QOL-CS), and Hospital Anxiety and Depression Scale (HADS)...

INTRODUCTION: Due to advances in critical care medicine, more patients survive their critical illness. However, intensive care unit (ICU) survivors often experience long-term physical, cognitive and mental problems, summarised as post-intensive care syndrome (PICS), impacting their health-related quality of life (HRQoL). In what frequency PICS occurs, and to what extent this influences ICU survivors' HRQoL, is mostly unknown. The aims of this study are therefore to study the: (1) 5-year patient outcomes, (2) predictors for PICS, (3) ratio between HRQoL of ICU survivors and healthcare-related costs, and (4) care and support needs...

Background: Atypical haemolytic uremic syndrome (aHUS) is a rare but severe form of thrombotic microangiopathy as a consequence of complement dysregulation. aHUS has a poor outcome with high mortality and >50% of patients developing end-stage renal disease. Since the end of 2012, these outcomes have greatly improved with the introduction of eculizumab. Currently the duration of treatment is debated. Most guidelines advise lifelong treatment. However, there is no hard evidence to support this advice...
