Influenza vaccination is proven effective in preventing influenza. However, long-term effects on mortality have never been supported by direct evidence. In this study we assessed the long-term outcome of influenza vaccination on mortality in the elderly by conducting a 25-year follow-up study of a RCT on the efficacy of influenza vaccination as baseline.

Background: Multidisciplinary rehabilitation has been recommended for multi-trauma patients, but there is only low-quality evidence to support its use with these patients. This study examined whether a Supported Fast track multi-Trauma Rehabilitation Service (Fast Track) was cost-effective compared to conventional trauma rehabilitation service (Care As Usual) in patients with multi-trauma from a societal perspective with a one-year follow-up.

Methods: An economic evaluation alongside a prospective, multi-center, non-randomized, controlled clinical study, was conducted in the Netherlands.

Objectives: The effects on health related outcomes of a newly-developed rehabilitation program, called 'supported Fast Track multi-trauma rehabilitation service' (Fast Track), were evaluated in comparison with conventional trauma rehabilitation service (Care as Usual).

Methods: Prospective, multi-center, non-randomized controlled study. Between 2009 and 2012, 132 adult multi-trauma patients were included: 65 Fast Track and 67 Care as Usual patients with an Injury Severity Score ≥16, complex multiple injuries in several extremities or complex pelvic and/or acetabulum fractures.

Purpose: To compare graft survival, best-corrected visual acuity (BCVA), endothelial cell density (ECD), and refraction following penetrating keratoplasty (PK) vs endothelial keratoplasty (EK) for Fuchs endothelial dystrophy (FED) and pseudophakic bullous keratopathy (PBK).

Design: Nonrandomized treatment comparison with national registry data.

Methods: All consecutive patients undergoing first keratoplasty for FED and PBK between 1998 and 2014 were analyzed, with a maximum follow-up of 5 years (mean ± SD follow-up 39 ± 20 months, range 0-60 months).

Background And Aims: In the past decades, treatment options and strategies for ulcerative colitis [UC] have radically changed. Whether these developments have altered the disease outcome at population level is yet unknown. Therefore, we evaluated the disease outcome of UC over the past two decades in the South-Limburg area of The Netherlands.

Background: The aim of the study was to evaluate whether adding a geriatric nurse practitioner (GNP) to an outpatient diagnostic multidisciplinary facility for patients with cognitive disorders (Diagnostic Observation Center for PsychoGeriatry, DOC-PG) could improve quality of care. DOC-PG combines hospital diagnostics and care assessment from a community mental health team and provides the general practitioner (GP) with advice for treatment and management. In a previous study, we found that 28.

Pubmed, Embase, and Cochrane were systematically reviewed for available evidence on bariatric surgery in adolescents. Thirty-seven included studies evaluated the effect of laparoscopic adjustable gastric banding (LAGB), Roux-en-Y gastric bypass (RYGB), or laparoscopic sleeve gastrectomy (LSG) in patients ≤18 years old. Fifteen of 37 studies were prospective, including one RCT.

Background: Small-scale, home-like care environments are increasingly implemented in institutional nursing care as a model to promote resident-directed care, although evidence on its effects is sparse. This study focuses on the effects of small-scale living facilities on the behavior of residents with dementia and use of physical restraints and psychotropic drugs.

Methods: A quasi-experimental study was conducted comparing residents in two types of long-term institutional nursing care (i.

Purpose: Vision loss is highly prevalent in old age and has a substantial impact on different aspects of quality of life including depressive symptoms. Our objective was to examine the mediating role of disability and social support in the association between low vision and depressive symptoms.

Methods: Differences in disability, social support, and depressive symptoms between 148 persons with low vision and a reference population (N = 4,792) all ≥57 years were compared.

Objective: This study examined the short-term and long-term effects of using a screening instrument on psychological distress and health-related quality of life (HRQoL) among cancer patients receiving radiotherapy. In addition, we investigated the effect of early psychosocial treatment on patients' overall health-related outcomes as previous research showed that patients in the screening condition were referred to a psychosocial caregiver at an earlier stage.

Methods: A cluster randomised controlled trial with a randomisation at the levels of 14 radiotherapists, 568 patients was conducted.

Objectives: To investigate whether the incidence of pressure ulcers in nursing homes in the Netherlands and Germany differs and, if so, to identify resident-related risk factors, nursing-related interventions, and structural factors associated with pressure ulcer development in nursing home residents.

Design: A prospective multicenter cohort study.

Setting: Ten nursing homes in the Netherlands and 11 nursing homes in Germany (around Berlin and Brandenburg).

Objectives: To assess the long-term effects of the EXBELT intervention program, which was designed to reduce belt restraint use and was found to be effective immediately after implementation, after 24 months.

Design: Quasi-experimental longitudinal design.

Setting: Thirteen nursing homes: seven assigned to control group and six to intervention group.

Background: Hepatitis C virus (HCV) is a major cause of liver diseases worldwide. Due to its asymptomatic nature, screening is necessary for identification. Because screening of the total population is not cost effective, it is important to identify which risk factors for positivity characterize the key populations in which targeting of screening yields the highest numbers of HCV positives, and assess which of these key populations have remained hidden to current care.

Background: Physical restraints are commonly used in psychogeriatric nursing home residents despite reports of negative consequences. Most research has focused on restraint reduction without addressing methods to prevent initiation of restraints in nursing homes. EXBELT has been found to decrease belt restraint use but should also be evaluated for its use in preventing restraints.

Hypotheses regarding the role of meat consumption in body weight modulation are contradictory. Prospective studies on an association between meat consumption and BMI change are limited. We assessed the association between meat consumption and change in BMI over time in 3902 men and women aged 55-69 y from the Netherlands Cohort Study.

Loss of the gut barrier, which is related to hypotension and gastrointestinal hypoperfusion during surgery, has been implicated as a critical event in postoperative complications development. This study aims at preventing gut barrier loss by maintenance of mean arterial pressure (MAP) in patients undergoing major nonabdominal surgery. In 20 previously included children undergoing spinal fusion surgery, the critical MAP value, which should be maintained to prevent enterocyte damage, was determined.

Aims: To re-estimate the SCORE risk function using individual data on risk factors and coronary heart disease (CHD) incidence from the Dutch Cardiovascular Registry Maastricht (CAREMA) population-based cohort study; to evaluate changes that may improve risk prediction after re-estimation; and to compare the performance of the resulting CAREMA risk function with that of existing risk scores.

Methods And Results: The cohort consisted of 21,148 participants, born in 1927-1977 and randomly sampled from the Maastricht region in 1987-1997. After follow-up (median 10.
