Background: During hospitalization patients frequently have a low level of physical activity, which is an important risk factor for functional decline. Function Focused Care (FFC) is an evidencebased intervention developed in the United States to prevent functional decline in older patients. Within FFC, nurses help older patients optimally participate in functional and physical activity during all care interactions. FFC was adapted to the Dutch Hospital setting, which led to Function Focused Care in Hospital (FFCiH). FFCiH consists of four components: (1) ‘Environmental and policy assessment’; (2) ‘Education’; (3) ‘Goal setting with the patient’ and (4) ‘Ongoing motivation and mentoring’. The feasibility of FFCiH in the Dutch hospital setting needs to be assessed. Objective: Introduce FFCiH into Dutch hospital wards, to assess the feasibility of FFCiH in terms of description of the intervention, implementation, mechanisms of impact, and context. Design: Mixed method design Setting(s): A Neurological and a Geriatric ward in a Dutch Hospital. Participants: 56 Nurses and nursing students working on these wards. Methods: The implementation process was described and the delivery was studied in terms of dose, fidelity, adaptions, and reach. The mechanisms of impact were studied by the perceived facilitators and barriers to the intervention. Qualitative data were collected via focus group interviews, observations, and field notes. Quantitative data were collected via evaluation forms and attendance/participation lists. Results: A detailed description of FFCiH in terms of what, how, when, and by whom was given. 54 Nurses (96.4%) on both wards attended at least 1 session of the education or participated in bedside teaching. The nurses assessed the content of the education sessions with a mean of 7.5 (SD 0.78) on a 0–10 scale. The patient files showed that different short and long-term goals were set. Several facilitators and barriers were identified, which led to additions to the intervention. An important facilitator was that nurses experienced FFCiH as an approach that fits with the principles underpinning their current working philosophy. The experienced barriers mainly concern the implementation elements of the FFCiH-components ‘Education’ and ‘Ongoing motivation and mentoring’. Optimizing the team involvement, improving nursing leadership during the implementation, and enhancing the involvement of patients and their family were activities added to FFCiH to improve future implementation. Conclusions: FFCiH is feasible for the Dutch hospital setting. Strong emphasis on team involvement, nursing leadership, and the involvement of patients and their families is recommended to optimize future implementation of FFCiH in Dutch hospitals.

The recent success of Machine Learning encouraged research using artificial neural networks (NNs) in computer graphics. A good example is the bidirectional texture function (BTF), a data-driven representation of surface materials that can encapsulate complex behaviors that would otherwise be too expensive to calculate for real-time applications, such as self-shadowing and interreflections. We propose two changes to the state-of-the-art using neural networks for BTFs, specifically NeuMIP. These changes, suggested by recent work in neural scene representation and rendering, aim to improve baseline quality, memory footprint, and performance. We conduct an ablation study to evaluate the impact of each change. We test both synthetic and real data, and provide a working implementation within the Mitsuba 2 rendering framework. Our results show that our method outperforms the baseline in all these metrics and that neural BTF is part of the broader field of neural scene representation.

Learning mathematical thinking and reasoning is a main goal in mathematical education. Instructional tasks have an important role in fostering this learning. We introduce a learning sequence to approach the topic of integrals in secondary education to support students mathematical reasoning while participating in collaborative dialogue about the integral-as-accumulation-function. This is based on the notion of accumulation in general and the notion of accumulative distance function in particular. Through a case-study methodology we investigate how this approach elicits 11th grade students’ mathematical thinking and reasoning. The results show that the integral-as-accumulation-function has potential, since the notions of accumulation and accumulative function can provide a strong intuition for mathematical reasoning and engage students in mathematical dialogue. Implications of these results for task design and further research are discussed.

Diminishing motor function is commonly observed in the elderly population and is associated with a wide range of adverse health consequences. Advanced Glycation End products (AGE’s) may contribute to age-related decline in the function of cells and tissues in normal ageing. Although the negative effect of AGE’s on the biomechanical properties of musculoskeletal tissues and the central nervous system have been previously described, the evidence regarding the effect on motor function is fragmented, and a systematic review on this topic is lacking. Therefore, a systematic review was conducted from a total of eight studies describing AGE’s related to physical functioning, physical performance, and musculoskeletal outcome which reveals a positive association between high AGE’s levels and declined walking abilities, inferior ADL, decreased muscle properties (strength, power and mass) and increased physical frailty. Elevated AGE’s levels might be an indication to initiate (early) treatment such as dietary advice, muscle strengthening exercises, and functional training to maintain physical functions. Further longitudinal observational and controlled trial studies are necessary to investigate a causal relationship, and to what extent, high AGE’s levels are a contributing risk factor and potential biomarker for a decline in motor function as a component of ageing process.

PURPOSE: To investigate whether the adapted version of the Gross Motor Function Measure-88 (GMFM-88) for children with Cerebral Palsy (CP) and Cerebral Visual Impairment (CVI) results in higher scores. This is most likely to be a reflection of their gross motor function, however it may be the result of a better comprehension of the instruction of the adapted version.METHOD: The scores of the original and adapted GMFM-88 were compared in the same group of children (n=21 boys and n=16 girls), mean (SD) age 113 (30) months with CP and CVI, within a time span of two weeks. A paediatric physical therapist familiar with the child assessed both tests in random order. The GMFCS level, mental development and age at testing were also collected. The Wilcoxon signed-rank test was used to compare two different measurements (the original and adapted GMFM-88) on a single sample, (the same child with CP and CVI; p<0.05).RESULTS: The comparison between scores on the original and adapted GMFM-88 in all children with CP and CVI showed a positive difference in percentage score on at least one of the five dimensions and positive percentage scores for the two versions differed on all five dimensions for fourteen children. For six children a difference was seen in four dimensions and in 10 children difference was present in three dimensions (GMFM dimension A, B& C or C, D & E) (p<0.001).CONCLUSION: The adapted GMFM-88 provides a better estimate of gross motor function per se in children with CP and CVI that is not adversely impacted bytheir visual problems. On the basis of these findings, we recommend using the adapted GMFM-88 to measure gross motor functioning in children with CP and CVI.

Background During acute hospital admission, patients often experience loss of functional status. A low level of physical activity is associated with higher levels of loss of functional status. Stimulating physical activity to maintain functional status is considered essential nursing care. Function Focused Care is a promising approach stimulating physical activity. In a previous study, Function Focused Care in Hospital was deemed feasible. Objective To determine the effectiveness of Function Focused Care in Hospital compared with usual care on the functional status of hospitalized stroke and geriatric patients. Design A multicenter stepped wedge cluster trial. Methods A neurological and a geriatric ward of an academic hospital and a general hospital in the Netherlands participated in this study; each was considered a cluster in the trial. The primary outcome was patients' functional status over time, measured with the Barthel Index and Elderly Mobility Scale. Secondary outcomes were the patients' length of stay, fear of falling, self-efficacy, motivation, resilience, and outcome expectations for functional and exercise activities. Data was collected at hospital admission (baseline), day of discharge, and three and six months after discharge via patient files and questionnaires and analyzed with generalized linear mixed models. Results In total, we included 892 patients, of which 427 received Function Focused Care in Hospital and 465 received usual care. Although we did not find significant differences in the Barthel Index and Elderly Mobility Scale at discharge or follow-up, we found a significant decrease in the mean length of stay (− 3.3 days, 95 % CI − 5.3 to − 1.1) in favor of the Function Focused Care in Hospital group. In addition, in the Function Focused Care in Hospital group, a larger proportion of patients were discharged to home compared to the control group (38.2 % vs. 29.0 %, p = 0.017), who were discharged more often to a care facility. Conclusion The length of hospital stay was substantially decreased, and discharge to home was more common in the group receiving Function Focused Care in Hospital with equal levels of independence in Activities of Daily Living and mobility in both groups upon discharge. Although significant differences in the Barthel Index and Elderly Mobility Scale were not found, we observed that neurological and geriatric patients were discharged significantly earlier compared to the control group.

BACKGROUND: Hemodynamic assessment of critically ill patients is a challenging endeavor, and advanced monitoring techniques are often required to guide treatment choices. Given the technical complexity and occasional unavailability of these techniques, estimation of cardiac function based on clinical examination is valuable for critical care physicians to diagnose circulatory shock. Yet, the lack of knowledge on how to best conduct and teach the clinical examination to estimate cardiac function has reduced its accuracy to almost that of "flipping a coin."OBJECTIVE: The aim of this study was to investigate the decision-making process underlying estimates of cardiac function of patients acutely admitted to the intensive care unit (ICU) based on current standardized clinical examination using Bayesian methods.METHODS: Patient data were collected as part of the Simple Intensive Care Studies-I (SICS-I) prospective cohort study. All adult patients consecutively admitted to the ICU with an expected stay longer than 24 hours were included, for whom clinical examination was conducted and cardiac function was estimated. Using these data, first, the probabilistic dependencies between the examiners' estimates and the set of clinically measured variables upon which these rely were analyzed using a Bayesian network. Second, the accuracy of cardiac function estimates was assessed by comparison to the cardiac index values measured by critical care ultrasonography.RESULTS: A total of 1075 patients were included, of which 783 patients had validated cardiac index measurements. A Bayesian network analysis identified two clinical variables upon which cardiac function estimate is conditionally dependent, namely, noradrenaline administration and presence of delayed capillary refill time or mottling. When the patient received noradrenaline, the probability of cardiac function being estimated as reasonable or good P(ER,G) was lower, irrespective of whether the patient was mechanically ventilated (P[ER,G|ventilation, noradrenaline]=0.63, P[ER,G|ventilation, no noradrenaline]=0.91, P[ER,G|no ventilation, noradrenaline]=0.67, P[ER,G|no ventilation, no noradrenaline]=0.93). The same trend was found for capillary refill time or mottling. Sensitivity of estimating a low cardiac index was 26% and 39% and specificity was 83% and 74% for students and physicians, respectively. Positive and negative likelihood ratios were 1.53 (95% CI 1.19-1.97) and 0.87 (95% CI 0.80-0.95), respectively, overall.CONCLUSIONS: The conditional dependencies between clinical variables and the cardiac function estimates resulted in a network consistent with known physiological relations. Conditional probability queries allow for multiple clinical scenarios to be recreated, which provide insight into the possible thought process underlying the examiners' cardiac function estimates. This information can help develop interactive digital training tools for students and physicians and contribute toward the goal of further improving the diagnostic accuracy of clinical examination in ICU patients.TRIAL REGISTRATION: ClinicalTrials.gov NCT02912624; https://clinicaltrials.gov/ct2/show/NCT02912624.

Background: Impaired upper extremity function due to muscle paresis or paralysis has a major impact on independent living and quality of life (QoL). Assistive technology (AT) for upper extremity function (i.e. dynamic arm supports and robotic arms) can increase a client’s independence. Previous studies revealed that clients often use AT not to their full potential, due to suboptimal provision of these devices in usual care. Objective: To optimize the process of providing AT for impaired upper extremity function and to evaluate its (cost-)effectiveness compared with care as usual. Methods: Development of a protocol to guide the AT provision process in an optimized way according to generic Dutch guidelines; a quasi-experimental study with non-randomized, consecutive inclusion of a control group (n = 48) receiving care as usual and of an intervention group (optimized provision process) (n = 48); and a cost-effectiveness and cost-utility analysis from societal perspective will be performed. The primary outcome is clients’ satisfaction with the AT and related services, measured with the Quebec User Evaluation of Satisfaction with AT (Dutch version; D-QUEST). Secondary outcomes comprise complaints of the upper extremity, restrictions in activities, QoL, medical consumption and societal cost. Measurements are taken at baseline and at 3, 6 and 9 months follow-up.

Abstract Aim: To determine whether the level of gross motor function and functional skills in children with cerebral palsy (CP) and cerebral visual impairment (CVI) as well as caregiver assistance are lower in comparison with the corresponding group of children experiencing CP without CVI. Method: Data aggregated from 23 children experiencing CP with CVI were compared with data from children with CP without CVI matched for Gross Motor Function Classifi cation System, mental development and age at testing. Scores for Gross Motor Function Measure-88 (GMFM-88) and the Pediatric Evaluation of Disability Inventory-NL (PEDI-NL) were employed to compare the level of gross motor function, functional skills and caregiver assistance between both groups. The Wilcoxon Signed Rank Test was utilized with a signifi cance level of p 0.05. Results: Children with CP with CVI, mean ( SD) age 6.4 1.5, scored signifi cantly lower than those with CP without CVI, mean age 6.3 1.6, on all GMFM-88 dimensions and the total score ( p 0.001) and on the PEDI-NL in the sections of Functional Skills and Caregiver Assistance as well as in those of domains self-care ( p 0.001), mobility ( p 0.001) and social functioning ( p 0.001). Concerning the modifi cations scale, the scores for children with CP and CVI were signifi cantly lower regarding mobility (no modifi cation , p 0.05), social functioning (no modifi cation, p 0.05) and social functioning (child-oriented, p 0.05). Conclusion: CVI contributes to diminished gross motor function and functional skills in children experiencing CP with CVI compared with children with CP without CVI. Children with CP and CVI also require increased support at the level of caregiver assistance. Specifi c interventions need to be developed for children experiencing CP with CVI in order to improve gross motor function, functional skills and caregiver assistance.

Generic self-management programs aim to facilitate behavioural adjustment and therefore have considerable potential for patients with chronic musculoskeletal pain. Our main objective was to collect and synthesize all data on the effectiveness of generic self-management interventions for patients with chronic musculoskeletal pain in terms of physical function, self-efficacy, pain intensity and physical activity. Our secondary objective was to describe the content of these interventions, by means of classification according to the Behaviour Change Technique Taxonomy. We searched PubMed, CENTRAL, Embase and Psycinfo for eligible studies. Study selection, data extraction and risk of bias were assessed by two researchers independently. Meta-analyses were only performed if the studies were sufficiently homogeneous and GRADE was used to determine the quality of evidence. We identified 20 randomized controlled trials that compared a self-management intervention to any type of control group. For post-intervention results, there was moderate quality evidence of a statistically significant but clinically unimportant effect for physical function and pain intensity, both favouring the self-management group. At follow-up, there was moderate quality evidence of a small clinically insignificant effect for self-efficacy, favouring the self-management group. All other comparisons did not indicate an effect. Classification of the behaviour change techniques showed large heterogeneity across studies. These results indicate that generic self-management interventions have a marginal benefit for patients with chronic musculoskeletal pain in the short-term for physical function and pain intensity and for self-efficacy in the long-term, and vary considerably with respect to intervention content. Significance: This study contributes to a growing body of evidence that generic self-management interventions have limited effectiveness for patients with chronic musculoskeletal pain. Furthermore, this study has identified substantial differences in both content and delivery mode across self-management interventions.
