The green computing aspects of low power consumption at high performance were somewhat tempered by long design cycles and hard programmability issues. However, in recent years FPGAs have become new contenders as versatile compute accelerators because of a growing market interest, extended application domains and maturing high-level synthesis tools. The keynote paper highlights the historical and modern approaches to high-level FPGA and the contributions cover applications such as NP-complete satisfiability problems and convex hull image processing as well as performance evaluation, partial reconfiguration and systematic design exploration." "Trends in prevalence and incidence of registered dementia and trends in multimorbidity among patients with dementia in general practice in Flanders, Belgium, 2000-2021: a registry-based, retrospective, longitudinal cohort study" "Simon Beerten, Jan De Lepeleire, Bert Vaes" "OBJECTIVES: With the ageing of our population, it seems plausible that the prevalence of both dementia and multimorbidity will increase in the following decades. The aim of this study is to examine the trends in prevalence and incidence of registered dementia and trends in multimorbidity in patients with dementia in general practice in Flanders. DESIGN: Retrospective, longitudinal cohort study. SETTING: Primary care practices across Flanders, Belgium. PARTICIPANTS: Patients included in the Intego database. METHODS: Data were collected from the Intego database, a Belgian general practice registration network, from 1 January 2000 to 31 December 2021. Joinpoint regression, the Cochran-Armitage test and Jonckheere-Terpstra test were used for the trend analysis. RESULTS: Data from 149 492 unique patients aged 65 years and older were available. From 2000 to 2021, 3835 incident cases of dementia were found. The age-adjusted prevalence of registered dementia significantly increased during this study period, from 1.19% to 2.43% (average annual percentage change (AAPC) 3.3; 95% CI 2.7 to 4.0). Incidence increased from 3.68 to 5.86 per 1000 patient years overall (AAPC 1.8, 95% CI -2.0 to 5.7), but declined in recent years (annual percentage change -8.1, 95% CI -14.8 to -0.8). Almost three-quarters of the patients with dementia (74.8%) suffered from multimorbidity (three or more comorbidities) and this increased significantly during the study period (p=0.0031). By 2021, 86.7% and 74.8% of the patients with dementia suffered from two or more or three or more chronic conditions, respectively. Hypertension (47.9%), osteoarthritis (29.7%) and lipid metabolism disorders (25.7%) were the most prevalent conditions. CONCLUSIONS: The prevalence of registered dementia doubled over a 22-year time period, mirroring the increasing health burden by this disease globally. Furthermore, three-quarters of the patients with dementia suffered from multimorbidity, underlining the urgent need to implement comorbidity management and patient-centred care in dementia." "Why have youth physical activity trends flatlined in the last decade? : Opinion piece on 'Global trends in insufficient physical activity among adolescents : a pooled analysis of 298 population-based surveys with 1.6 million participants' by Gutho" "Greet Cardon, Jo Salmon" "International trends in health science librarianship, part 2 : Northern Europe : trends in academic medical information management in Belgium over the last 10 years" "Ghislaine Declève, Henri Verhaaren" "Assessing trends in population size of three unmarked species: A comparison of a multi-species N-mixture model and random encounter models" "Martijn BOLLEN, Pablo Palencia, Joaquin Vicente, Pelayo Acevedo, Lucia Del Rio, Thomas NEYENS, Natalie BEENAERTS, Jim Casaer" "Estimation of changes in abundances and densities is essential for the research, management, and conservation of animal populations. Recently, technological advances have facilitated the surveillance of animal populations through the adoption of passive sensors, such as camera traps (CT). Several methods, including the random encounter model (REM), have been developed for estimating densities of unmarked populations but require additional information. Hierarchical abundance models, such as the N-mixture model (NMM), can estimate abundances without performing additional fieldwork but do not explicitly estimate the area effectively sampled. This obscures the interpretation of its densities and requires its users to focus on relative measures of abundance instead. Hence, the main objective of our study is to evaluate if REM and NMM yield consistent results qualitatively. Therefore, we compare relative trends: (i) between species, (ii) between years and (iii) across years obtained from annual density/abundance estimates of three species (fox, wild boar and red deer) in central Spain monitored by a camera trapping network for five consecutive winter periods. We reveal that NMM and REM provided density estimates in the same order of magnitude for wild boar, but not for foxes and red deer. Assuming a Poisson detection process in the NMM was important to control for inflation of abundance estimates for frequently detected species. Both methods consistently ranked density/abundance across species (between species trend), but did not always agree on relative ranks of yearly estimates within a single population (between years trend), nor on its linear population trends across years (across years trend). Our results suggest that relative trends are generally consistent when the range of variability is large, but can become inconsistent when the range of variability is smaller." "Trends in sleeping difficulties among European adolescents." "Ariane Ghekiere, Jelle Van Cauwenberg, Jorma Tynjälä, Benedicte Deforche" "Objectives: We examined changes in sleep-onset difficulties over time and associations with physical activity and screen time behavior among adolescents. Methods: We used data from last four survey waves of the Health Behavior in School-Aged Children (HBSC) study (2002–2006–2010–2014). Multilevel logistic regression analyses were conducted to explore associations between regular sleeping difficulties, excessive screen time exposure and being insufficiently physically active (i.e., < 60 min daily) among 33 European and non-European countries. Results: Findings indicate an increase in the prevalence of sleep-onset difficulties and in excessive screen time exposure and a small but significant increase in physical activity levels. Additionally, adolescents exceeding 2-h daily screen time had 20% higher odds of reporting sleep-onset difficulties, while no association was found for physical activity. The strength of the association between screen time and sleep-onset difficulties increased over time, which may reflect a change in type of screen time use (e.g., the increased use of easy accessible screens such as smartphones and tablets). Conclusions: Effective strategies to reduce screen time are key to reverse the detrimental trend in sleep-onset difficulties among adolescents."

Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure.Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probit-transformed) prevalence of raised blood pressure and age-group-and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure.Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the high-income Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association.Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups." "Modeling future cardiovascular disease mortality in the United States: national trends and racial and ethnic disparities" "Jonathan Pearson-Stuttard, Maria Guzman-Castillo, Jose Luis Peñalvo, Colin D Rehm, Ashkan Afshin, Goodarz Danaei, Chris Kypridemos, Tom Gaziano, Dariush Mozaffarian, Simon Capewell, Martin O'Flaherty" "Background-Accurate forecasting of cardiovascular disease mortality is crucial to guide policy and programming efforts. Prior forecasts often have not incorporated past trends in rates of reduction in cardiovascular disease mortality. This creates uncertainties about future trends in cardiovascular disease mortality and disparities.Methods and Results-To forecast US cardiovascular disease mortality and disparities to 2030, we developed a hierarchical bayesian model to determine and incorporate prior age, period, and cohort effects from 1979 to 2012, stratified by age, sex, and race, which we combined with expected demographic shifts to 2030. Data sources included the National Vital Statistics System, Surveillance, Epidemiology, and End Results (SEER) single-year population estimates, and US Bureau of Statistics 2012 national population projections. We projected coronary disease and stroke deaths to 2030, first on the basis of constant age, period, and cohort effects at 2012 values, as is most commonly done (conventional), and then with the use of more rigorous projections incorporating expected trends in age, period, and cohort effects (trend based). We primarily evaluated absolute mortality. The conventional model projected total coronary and stroke deaths by 2030 to increase by approximate to 18% (67 000 additional coronary deaths per year) and 50% (64 000 additional stroke deaths per year). Conversely, the trend-based model projected that coronary mortality would decrease by 2030 by approximate to 27% (79 000 fewer deaths per year) and stroke mortality would remain unchanged (200 fewer deaths per year). Health disparities will be improved in stroke deaths but not coronary deaths.Conclusions-After prior mortality trends and expected demographic shifts are accounted for, total US coronary deaths are expected to decline, whereas stroke mortality will remain relatively constant. Health disparities in stroke but not coronary deaths will be improved but not eliminated. These age, period, and cohort approaches offer more plausible predictions than conventional estimates." "Trends in familiebeoordelingen van kwaliteit van levenseindezorg en van sterven bij dementie." "Annelies Vandersteen, Mc Van Soest-Poortvliet, Mjhe Gijsberts, Bregje Onwuteaka-Philipsen, Wp Achterberg, Mw Ribbe, Luc Deliens, Hc De Vet" "Abstract OBJECTIVE: To analyse possible trends in families' evaluations of the quality of end-of-life care and the quality of dying in dementia. DESIGN: Analysis of individual patient data from 3 studies (2 solely retrospective (after death) and 1 partly prospective). METHOD: We combined data on 372 residents with dementia from 38 nursing homes and 13 residential homes ('psychogeriatric' wards) over the period 2005-2010. Outcome measures were the End-of-Life in Dementia-Satisfaction With Care scale (EOLD-SWC; range: 10-40) to assess quality of, or satisfaction with, end-of-life care, and the EOLD-Comfort Assessment in Dying scale (EOLD-CAD; range: 12-42) to assess quality of dying (comfort). Regression analyses were performed with time (trend) as an independent factor and were adjusted for clustering of residents within homes. We also adjusted for differences between residents, homes, and study designs. RESULTS: We found a consistent trend of increasing family satisfaction with end-of-life care over the years (unadjusted: 0.5 points per year increment on the EOLD-SWC, and adjusted: 1.2 points; mean total score: 32.4 (SD: 5.3)). Results for the EOLD-CAD scale (mean: 32.2 (SD: 5.7)) were inconclusive; only the exclusively retrospective data indicated increased comfort. Item- and subscale-level analyses showed that, in particular, families were more satisfied with general (comfort) measures for residents and the emotional support provided for families; further, families reported lower levels of emotional distress in residents. CONCLUSION: We found a positive trend of increased satisfaction with end-of-life care. Families also reported a possible increase in residents' end-of-life comfort. Ongoing surveillance of outcomes measuring end-of-life quality is important in view of the increasing healthcare budget constraints"
