  • Augmedicine: Ultrasound: Training in ultrasound using XR – a randomized controlled trial

    Open Access•Tessa A Mulder, Robin C Jacobs et al.•ARTICLE•BMC Medical Education•2026

    BACKGROUND: Point-of-care ultrasound (POCUS) is a diagnostic tool increasingly used. For novices, challenges such as probe orientation and hand-eye coordination make POCUS difficult to master. Extended reality (XR) can enhance POCUS training by projecting 3D anatomical models and offering real-time feedback on probe positioning. We developed the ‘Augmedicine: Ultrasound’ XR application, which enables heart POCUS training without the need for an i…

  • Twelve tips for fostering the next generation of medical teachers

    Open Access•Charlotte R den Bakker, Renée A Hendriks et al.•ARTICLE•Medical Teacher•2022

    Medical professionals with a special interest in and focus on education are essential to provide good quality education. Despite high numbers of students expressing an interest in teaching, concerns are rising regarding the supply of medical teachers, with few junior educators on the career ladder. To date, only some medical schools offer in-depth courses to students wanting to explore or aspire a career as a specialised medical teacher. We propo…

  • Dimensions of Depressive Symptoms and Their Association With Mortality, Hospitalization, and Quality of Life in Dialysis Patients: A Cohort Study

    Open Access•Robbert W Schouten, Victor J Harmse et al.•ARTICLE•Psychosomatic Medicine•2019

    OBJECTIVE: Unraveling specific dimensions of depressive symptoms may help to improve screening and treatment in dialysis patients. We aimed to identify the best-fitting factorial structure for the Beck Depression Inventory-II (BDI) in dialysis patients and to assess the relation of these structure dimensions with quality of life (QoL), hospitalization, and mortality. METHODS: This prospective study included chronic dialysis patients from 10 dialy…

  • Longitudinal Associations Between Inflammation and Depressive Symptoms in Chronic Dialysis Patients

    Gertrud L G Haverkamp, Wim L Loosman et al.•ARTICLE•Psychosomatic Medicine•2019

    OBJECTIVE: Patients undergoing chronic dialysis often display sustained elevations of inflammation markers and also have a high prevalence of depressive symptoms. Although multiple studies demonstrated cross-sectional associations between inflammation markers and depressive symptoms in this patient group, longitudinal associations have not been examined. We therefore investigated whether longitudinal associations exist between inflammation marker…

  • Ethnic Differences in the Association of Depressive Symptoms with Clinical Outcome in Dialysis Patients

    Open Access•Robbert W Schouten, Gerlinde L Haverkamp et al.•ARTICLE•Journal of Racial and Ethnic…•2019•Cited by: 1•References: 43

    Depressive symptoms are a risk factor for hospitalization and mortality, especially in native dialysis patients. Adverse clinical events associated with depressive symptoms differ among ethnic groups. This differential association could play a role in the conflicting findings in literature. Ethnicity is an important factor when investigating depressive symptoms and clinical outcome in dialysis patients. Future research should focus on the possibl…

  • Depressive and Anxiety Symptoms in Dutch Immigrant and Native Dialysis Patients

    Open Access•Wim L Loosman, Gertrud L G Haverkamp et al.•ARTICLE•Journal of Immigrant and Minority…•2018

  • Illness Perceptions in Patients on Predialysis Care: Associations With Time Until Start of Dialysis and Decline of Kidney Function

    Yvette Meuleman, Moniek C M de Goeij et al.•ARTICLE•Psychosomatic Medicine•2015

    OBJECTIVES: Illness perceptions in patients with end-stage renal disease are associated with nonadherence and increased mortality. However, no data are available regarding the relationship between illness perceptions and accelerated disease progression in predialysis patients. METHODS: A total of 416 incident predialysis patients participating in a prospective cohort (PREPARE-2, Predialysis Patient Record-2) completed the Revised Illness Percepti…

  • Short-Term Versus Long-Term Effects of Depressive Symptoms on Mortality in Patients on Dialysis

    Sandra van Dijk, Tessa O van den Beukel et al.•ARTICLE•Psychosomatic Medicine•2012

    In Brief Objective Depressive symptoms seem to pose a risk factor for mortality among patients on dialysis. It is currently unknown whether the association is only short-lived and whether associations over time depend on specific causes of mortality. Methods In a prospective nationwide cohort study, 1528 patients with end-stage renal disease starting on dialysis completed the Mental Health Inventory. Patients were observed up to 5 years or until …

  • Referral patterns of children with poor growth in primary health care

    Open Access•Floor K Grote, Wilma Oostdijk et al.•ARTICLE•BMC Public Health•2007

    The current Dutch consensus guideline leads to too many referrals, mainly due to the deflection of length during the first 3 years of life. The UKCG leads to far less referrals, but may be relatively insensitive to detect clinically relevant growth disorders like Turner syndrome. New guidelines for growth monitoring are needed, which combine a low percentage of false positive results with a good sensitivity
