In het herstellen en behouden van zinvolle bezigheden voor mensen met een lichte of matige vorm van van de ziekte van Alzheimer is doelstelling van groot praktisch belang. De studies gericht op dit doel hebben vertrouwd op de verschillende strategieën van zelfmanagement van instruction cues. Zeven studies werden gevonden die plaats hadden in de periode 2008-2012 (dat wil zeggen, de periode waarin onderzoek op dit gebied daadwerkelijk vorm heeft gekregen). Die strategieën bestaan uit het gebruik van (1) verbale signalen aangeboden via audiorecorders, (2) visuele signalen aangeboden via computersystemen, en (3) een combinatie van verbale en visuele signalen gepresenteerd via computersystemen. Dit artikel geeft een overzicht van de hiervoor genoemde strategieën en bespreekt de resultaten daarvan, hun algemene doeltreffendheid, op prestaties en stemmingen, en hun geschiktheid en bruikbaarheid. Thema's voor toekomstig onderzoek werden eveneens onderzocht. ABSTRACT Helping people with mild or moderate Alzheimer's disease restore and maintain constructive occupations is an objective of great practical importance. Studies targeting this goal have relied on different strategies for self-management of instruction cues. Seven studies were identified in the period 2008- 2012 (i.e. the period in which research in this area has actually taken shape). These strategies consist of the use of (1) verbal cues presented via audio recording devices, (2) pictorial cues presented via computer-aided systems and (3) combinations of verbal and pictorial cues presented via computer-aided systems. This paper reviews these strategies and discusses their outcomes, their overall effectiveness on performance and mood, and their suitability and practicality. Issues for future research are also examined.
BACKGROUND: Physical activity (PA) is important for children with a chronic disease. Serious games may be useful to promote PA levels among these children.OBJECTIVE: The primary purpose of this systematic review was to evaluate the effectiveness of serious games on PA levels in children with a chronic disease.METHODS: PubMed, EMBASE, PsycINFO, ERIC, Cochrane Library, and CINAHL were systematically searched for articles published from January 1990 to May 2018. Both randomized controlled trials and controlled clinical trials were included to examine the effects of serious games on PA levels in children with a chronic disease. Two investigators independently assessed the intervention, methods, and methodological quality in all articles using the Cochrane risk of bias tool. Both qualitative and quantitative analyses were performed.RESULTS: This systematic review included 9 randomized controlled trials (886 participants). In 2 of the studies, significant between-group differences in PA levels in favor of the intervention group were reported. The meta-analysis on PA levels showed a nonsignificant effect on moderate to vigorous PA (measured in minutes per day) between the intervention and control groups (standardized mean difference 0.30, 95% CI -0.15 to 0.75, P=.19). The analysis of body composition resulted in significantly greater reductions in BMI in the intervention group (standardized mean difference -0.24, 95% CI -0.45 to 0.04, P=.02).CONCLUSIONS: This review does not support the hypothesis that serious games improve PA levels in children with a chronic disease. The meta-analysis on body composition showed positive intervention effects with significantly greater reductions in BMI in favor of the intervention group. A high percentage of nonuse was identified in the study of serious games, and little attention was paid to behavior change theories and specific theoretical approaches to enhance PA in serious games. Small sample sizes, large variability between intervention designs, and limited details about the interventions were the main limitations. Future research should determine which strategies enhance the effectiveness of serious games, possibly by incorporating behavior change techniques.
Chest physical therapy (CPT) is a widely used intervention for patients with airway diseases. The main goal is to facilitate secretion transport and thereby decrease secretion retention in the airways. Historically, conventional CPT has consisted of a combination of forced expirations (directed cough or huff), postural drainage, percussion, and/or shaking. CPT improves mucus transport, but it is not entirely clear which groups of patients benefit from which CPT modalities. In general, the patients who benefit most from CPT are those with airways disease and objective signs of secretion retention (eg, persistent rhonchi or decreased breath sounds) or subjective signs of difficulty expectorating sputum, and with progression of disease that might be due to secretion retention (eg, recurrent exacerbations, infections, or a fast decline in pulmonary function). The most effective and important part of conventional CPT is directed cough. The other components of conventional CPT add little if any benefit and should not be used routinely. Alternative airway clearance modalities (eg, high-frequency chest wall compression, vibratory positive expiratory pressure, and exercise) are not proven to be more effective than conventional CPT and usually add little benefit to conventional CPT. Only if cough and huff are insufficiently effective should other CPT modalities be considered. The choice between the CPT alternatives mainly depends on patient preference and the individual patient's response to treatment.
MULTIFILE
Every year in the Netherlands around 10.000 people are diagnosed with non-small cell lung cancer, commonly at advanced stages. In 1 to 2% of patients, a chromosomal translocation of the ROS1 gene drives oncogenesis. Since a few years, ROS1+ cancer can be treated effectively by targeted therapy with the tyrosine kinase inhibitor (TKI) crizotinib, which binds to the ROS1 protein, impairs the kinase activity and thereby inhibits tumor growth. Despite the successful treatment with crizotinib, most patients eventually show disease progression due to development of resistance. The available TKI-drugs for ROS1+ lung cancer make it possible to sequentially change medication as the disease progresses, but this is largely a ‘trial and error’ approach. Patients and their doctors ask for better prediction which TKI will work best after resistance occurs. The ROS1 patient foundation ‘Stichting Merels Wereld’ raises awareness and brings researchers together to close the knowledge gap on ROS1-driven oncogenesis and increase the options for treatment. As ROS1+ lung cancer is rare, research into resistance mechanisms and the availability of cell line models are limited. Medical Life Sciences & Diagnostics can help to improve treatment by developing new models which mimic the situation in resistant tumor cells. In the current proposal we will develop novel TKI-resistant cell lines that allow screening for improved personalized treatment with TKIs. Knowledge of specific mutations occurring after resistance will help to predict more accurately what the next step in patient treatment could be. This project is part of a long-term collaboration between the ROS1 patient foundation ‘Stichting Merels Wereld’, the departments of Pulmonary Oncology and Pathology of the UMCG and the Institute for Life Science & Technology of the Hanzehogeschool. The company Vivomicx will join our consortium, adding expertise on drug screening in complex cell systems.
How does a specific lung cancer become resistant towards medication.The occurrence of a chromosomal translocation resulting in a ROS1 gene fusion in lung cancer is relatively rare with around 1-2% of all cases. Both Dutch (Stichting Merels Wereld) and world-wide (ROS1ders) patient advocacy groups work hard to raise awareness and bring researchers together to close the knowledge gap on ROS1 driven oncogenesis and increase the optionsfor treatment. A notorious hurdle is to achieve durable responses due to development of resistance.Ongoing mutations occurring in tumour cells lead to a heterogeneous genomic landscape and will result in outgrowth of the fastest growing tumour cell population resistant to the applied drug. The currently known resistance mechanisms can be divided in on-target (i.e. mutations in the kinasedomain of ROS1) and off-target (providing ROS1 independent growth support) mechanisms. The currently available drugs target the ROS1-fusion gene positive lung cancer cells. In addition, some of the drugs also target cancer cells with specific ROS1 resistance mutations allowing effective sequentialtreatment upon disease progression. Selection of the most optimal treatment is largely a ‘trial and error’ approach. Patients and their doctors ask for better prediction of the most effective follow-up treatment upon development of resistance. Medical Life Science & Diagnostics can help to improvetreatment by developing cell culture models which mimic the situation in resistant tumour cells.Understanding the impact of specific mutations on disease behaviour will aid in the development of patient-tailored therapeutic approaches, ultimately improving patient outcomes.
