Survnvote: a free web based audience response system to support interactivity in the classroom

Survnvote is a free Audience Response System (ARS) for surveys and voting using the web, sms and mobile devices (PDA or smart phone). This paper proposed some improved features of a web-based ARS which replace the clicker with mobile phone and use the web instead of specialist software and infrastructure. Survnvote solved the main problem of traditional ARS which is high cost and need to physically install the receivers in the room. This system offers a more user friendly approach and improved features, e.g. the introduction of crowd management, Survnvote panel that is easy to use, crowd group voting, and several ways to participate in voting. This system gives a better result representation by providing several data formats such as graph, PowerPoint, Excel. Survnvote also provides data analysis to the user. ARS users will experience valuable services by utilizing this system to support interactivity in their classrooms, seminars and conferences. A test-case of the use of this system in a lecture class is provided in this paper

Estimates of Mortality Benefit From Ideal Cardiovascular Health Metrics: A Dose Response Meta-Analysis

Background Several studies have shown an inverse relationship between ideal cardiovascular health (CVH) and mortality. However, there are no studies that pool these data to show the shape of the relationship and quantify the mortality benefit from ideal CVH. Methods and Results We conducted a systematic internet literature search of multiple databases including MEDLINE, Web of Science, Embase, CINAHL, and Scopus for longitudinal studies assessing the relationship between ideal CVH and mortality in adults, published between January 1, 2010, and May 31, 2017. We included studies that assessed the relationship between ideal CVH and mortality in populations that were initially free of cardiovascular disease. We conducted a dose‐response meta‐analysis generating both study‐specific and pooled trends from the correlated log hazard ratio estimates of mortality across categories of ideal CVH metrics. A total of 6 studies were included in the meta‐analysis. All of the studies indicated a linear decrease in (cardiovascular disease and all‐cause) mortality with increasing ideal CVH metrics. Overall, each unit increase in CVH metrics was associated with a pooled hazard ratio for cardiovascular disease mortality of 0.81 (95% confidence interval, 0.75–0.87), while each unit increase in ideal CVH metrics was associated with a pooled hazard ratio of 0.89 (95% confidence interval, 0.86–0.93) for all‐cause mortality. Conclusions Our meta‐analysis showed a strong inverse linear dose‐response relationship between ideal CVH metrics and both all‐cause and cardiovascular disease–related mortality. This study suggests that even modest improvements in CVH is associated with substantial mortality benefit, thus providing a strong public health message advocating for even the smallest improvements in lifestyle

The relationship of erectile dysfunction and subclinical cardiovascular disease: A systematic review and meta-analysis

Erectile dysfunction (ED) is associated with cardiovascular disease (CVD) and CVD mortality. However, the relationship between ED and subclinical CVD is less clear. We synthesized the available data on the association of ED and measures of subclinical CVD. We searched multiple databases for published literature on studies examining the association of ED and measures of subclinical CVD across four domains: endothelial dysfunction measured by flow-mediated dilation (FMD), carotid intima–media thickness (cIMT), coronary artery calcification (CAC), and other measures of vascular function such as the ankle–brachial index, toe–brachial index, and pulse wave velocity. We conducted random effects meta-analysis and meta-regression on studies that examined an ED relationship with FMD (15 studies; 2025 participants) and cIMT (12 studies; 1264 participants). ED was associated with a 2.64 percentage-point reduction in FMD compared to those without ED (95% CI: –3.12, −2.15). Persons with ED also had a 0.09-mm (95% CI: 0.06, 0.12) higher cIMT than those without ED. In subgroup meta-analyses, the mean age of the study population, study quality, ED assessment questionnaire (IIEF-5 or IIEF-15), or the publication date did not significantly affect the relationship between ED and cIMT or between ED and FMD. The results for the association of ED and CAC were inconclusive. In conclusion, this study confirms an association between ED and subclinical CVD and may shed additional light on the shared mechanisms between ED and CVD, underscoring the importance of aggressive CVD risk assessment and management in persons with ED

Lipoprotein sub-fractions by ion-mobility analysis and its association with subclinical coronary atherosclerosis in high-risk individuals

Aims: There is limited knowledge about the association of lipoprotein particles and markers of coronary atherosclerosis such as coronary artery calcification (CAC) in relatively young high-risk persons. This study examines the association of lipoprotein subfractions and CAC in high cardiometabolic risk individuals. Methods: The study presents analysis from baseline data of a randomized trial targeted at high-risk workers. Employees of Baptist Health South Florida with metabolic syndrome or diabetes were recruited. At baseline, all 182 participants had lipoprotein subfraction analysis using the ion mobility technique and participants above 35 years (N =170) had CAC test done. Principal components (PC) were computed for the combination of lipoprotein subclasses. Multiple bootstrapped regression analyses (BSA) were conducted to assess the relationship between lipoprotein subfractions and CAC. Results: The study population (N=170) was largely female (84%) with a mean age of 58 years. Three PCs accounted for 88% variation in the sample. PC2, with main contributions from VLDL particles in the positive direction and large LDL particles in the negative direction was associated with a 22% increase in CAC odds (P value ＜0.05 in 100% of BSA). PC3, with main contributions from HDL lipoprotein particles in the positive direction and small/medium LDL and large IDL particles in the negative direction, was associated with a 9% reduction in CAC odds (P＜0.05 in 88% of BSA). PC1, which had approximately even contributions from HDL, LDL, IDL and VLDL lipoprotein subfractions in the positive direction, was not associated with CAC. Conclusion: In a relatively young but high-risk population, a lipoprotein profile predominated by triglyceride-rich lipoproteins was associated with increased risk of CAC, while one predominated by HDL lipoproteins offered modest protection. Lipoprotein sub-fraction analysis may help to further discriminate patients who require more intensive cardiovascular work-up and treatment

Cloud versus Edge: Who Serves the Internet-of-Things Better?

Usually announced to the ICT community as rivals in the Internet-of-Things (IoT) context, cloud and edge could work together according to their respective capabilities. Today’s IoT applications cannot be dependent on a single technology (either SQL or noSQL) nor a single operation model (either centralized or decentralized). The challenges are multiple including complexity of user scenarios, multiplicity of things, sensitivity of data, etc. This paper raises the question of who serves IoT better? Cloud, only; edge, only; or both together. To answer this question, clouds’ and edges’ duties are identified and then a set of collaborative scenarios are discussed with respect to these duties

Economic Impact of Moderate‐Vigorous Physical Activity Among Those With and Without Established Cardiovascular Disease: 2012 Medical Expenditure Panel Survey

Background Physical activity (PA) has an established favorable impact on cardiovascular disease (CVD) outcomes and quality of life. In this study, we aimed to estimate the economic effect of moderate‐vigorous PA on medical expenditures and utilization from a nationally representative cohort with and without CVD. Methods and Results The 2012 Medical Expenditure Panel Survey data were analyzed. Our study population was limited to noninstitutionalized US adults ≥18 years of age. Variables of interest included CVD (coronary artery disease, stroke, heart failure, dysrhythmias, or peripheral artery disease) and cardiovascular modifiable risk factors (CRFs; hypertension, diabetes mellitus, hypercholesterolemia, smoking, and/or obesity). Two‐part econometric models were utilized to study cost data; a generalized linear model with gamma distribution and link log was used to assess expenditures per capita. The final study sample included 26 239 surveyed individuals. Overall, 47% engaged in moderate‐vigorous PA ≥30 minutes, ≥5 days/week, translating to 111.5 million adults in the United States stratifying by CVD status; 32% reported moderate‐vigorous PA among those with CVD versus 49% without CVD. Generally, participants reporting moderate‐vigorous PA incurred significantly lower health care expenditures and resource utilization, displaying a step‐wise lower total annual health care expenditure as moving from CVD to non‐CVD (and each CRF category). Conclusions Moderate‐vigorous PA ≥30 minutes, ≥5 days/week is associated with significantly lower health care spending and resource utilization among individuals with and without established CVD

Malleability of the cortical hand map following a finger nerve block

Electrophysiological studies in monkeys show that finger amputation triggers local remapping within the deprived primary somatosensory cortex (S1). Human neuroimaging research, however, shows persistent S1 representation of the missing hand’s fingers, even decades after amputation. Here, we explore whether this apparent contradiction stems from underestimating the distributed peripheral and central representation of fingers in the hand map. Using pharmacological single-finger nerve block and 7-tesla neuroimaging, we first replicated previous accounts (electrophysiological and other) of local S1 remapping. Local blocking also triggered activity changes to nonblocked fingers across the entire hand area. Using methods exploiting interfinger representational overlap, however, we also show that the blocked finger representation remained persistent despite input loss. Computational modeling suggests that both local stability and global reorganization are driven by distributed processing underlying the topographic map, combined with homeostatic mechanisms. Our findings reveal complex interfinger representational features that play a key role in brain (re)organization, beyond (re)mapping
