Towards a personalised approach in exercise-based cardiovascular rehabilitation: How can translational research help?: A ‘call to action’ from the Section on Secondary Prevention and Cardiac Rehabilitation of the European Association of Preventive Cardiology

Gevaert, Andreas B., Adams, Volker, Bahls, Martin, Bowen, T. Scott, Cornelissen, Veronique, Dörr, Marcus, Hansen, Dominique, Kemps, Hareld M.C., Leeson, Paul, Van Craenenbroeck, Emeline M., Kränkel, Nicolle 13 January 2023 (has links)
The benefit of regular physical activity and exercise training for the prevention of cardiovascular and metabolic diseases is undisputed. Many molecular mechanisms mediating exercise effects have been deciphered. Personalised exercise prescription can help patients in achieving their individual greatest benefit from an exercise-based cardiovascular rehabilitation programme. Yet, we still struggle to provide truly personalised exercise prescriptions to our patients. In this position paper, we address novel basic and translational research concepts that can help us understand the principles underlying the inter-individual differences in the response to exercise, and identify early on who would most likely benefit from which exercise intervention. This includes hereditary, non-hereditary and sex-specific concepts. Recent insights have helped us to take on a more holistic view, integrating exercise-mediated molecular mechanisms with those influenced by metabolism and immunity. Unfortunately, while the outline is recognisable, many details are still lacking to turn the understanding of a concept into a roadmap ready to be used in clinical routine. This position paper therefore also investigates perspectives on how the advent of ‘big data’ and the use of animal models could help unravel interindividual responses to exercise parameters and thus influence hypothesis-building for translational research in exercisebased cardiovascular rehabilitation.

Lind, Eric J., Murray, Steve, Stevens, Ilya, Drozdowski, Nick 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A systems engineering development for acquisition, transmission, processing, dissemination and display of information vital to combat casualty care and related first responder activities is presented. It utilizes a synergistic combination of two existing state-of-the-art Defense Advanced Research Projects Agency/Space and Naval Warfare Systems Center San Diego (DARPA/SSCSD) technologies (Sensate-Liner and ENCOMPASS) coupled via the Enhanced Position Location Reporting System (EPLRS), an existing wireless military tactical communication data system. Transmission Security and Communication Security (TRANSEC/COMMSEC) of environmental and biomedical data is thus accomplished from the battlefield via selected data links and Ethernet. System functionality and appropriate candidate interfacing technologies will be discussed.

No. of bitstreams: 1 Marcio Borges Moreira.pdf: 1127793 bytes, checksum: efefd6c330ef947e1e02cb9c1d3425d1 (MD5) Previous issue date: 2005-03-11 / Um dos grandes desafios, históricos e atuais, da Análise Experimental do Comportamento consiste em explorar conceitual e metodologicamente como estímulos, ou relações entre estímulos, passam a controlar um determinado comportamento, sobre tudo o comportamento humano. Os trabalhos iniciados por Sidman em 1971 alargaram os horizontes da Análise Experimental do Comportamento neste campo de estudos, sobretudo ao que se refere à linguagem e/ou comportamento simbólico. As extensões, ramificações e derivações dos trabalhos de Sidman têm gerado desde então incontáveis trabalhos empíricos e teóricos. A natureza do operante discriminado tomou vertentes e vultos bastante diferentes e complexos, por conseguinte, extensas discussões sugiram. O presente trabalho tenta contribuir com estas discussões e teve como objetivo propor um procedimento de treino discriminativo alternativo às propostas atuais sobre responder relacional e emergência de relações entre estímulos, baseado em discriminações simples simultâneas e utilizando-se estímulos compostos. Os resultados obtidos mostram ser o procedimento viável para o estudo do responder relacional e emergência de relações entre estímulos. Sugerem ainda uma reflexão sobre as características definidoras do responder relacional e emergência de relações entre estímulos. Indicam também que o repertório comportamental pré-experimento dos participantes é uma variável bastante relevante e que deve ser considerada e estudada como mais atenção.

Efeitos de consequências culturais sobre estimativas de controle em trios e sobre o responder individual em uma tarefa com pontos não contingentes / Effects of cultural consequences on estimates of control in trios and on the individual responding in a task involving non-contingent points

Araújo, Lorena Alves de Souza 23 May 2014 (has links)
Quando colocadas em situações em que os eventos ambientais são independentes do responder, pessoas podem desenvolver uma expectativa inapropriada de que têm controle comportamental sobre o ambiente. Esse fenômeno é conhecido como ilusão de controle. Este estudo investigou os efeitos de consequências culturais sobre as estimativas de controle apresentadas consensualmente por um trio de participantes, que trabalharam em uma tarefa em que pontos foram apresentados independentemente do responder. 38 universitários de diversos cursos de graduação participaram de 2 experimentos: no Experimento 1, quatro Trios realizaram a tarefa experimental e no Experimento 2, duas Culturas envolveram a substituição de participantes. Duas atividades caracterizavam um ciclo completo: (a) em primeiro lugar, uma tarefa individual na qual pontos foram apresentados na tela do computador, em um esquema múltiplo com componentes de tempo variável e extinção (mult VT EXT). Abaixo do rótulo de pontos, havia um retângulo, que mudava de cor a depender do componente do esquema, manipulável pelos participantes por meio de respostas de teclar na barra de espaço do teclado. (b) Em segundo lugar, após o término da tarefa no computador, os participantes responderam consensualmente sobre o controle que tinham na produção dos pontos em uma escala que variou entre depender pouco (0) e depender muito (10). Consequências culturais foram apresentadas a depender da estimativa de controle e da condição vigente. Na condição A, a consequência cultural foi apresentada contingente a estimativas de controle entre 7 e 10. Já na condição B, a consequência cultural foi contingente a estimativas entre 0 e 3. Os resultados encontrados contribuem tanto para os estudos sobre seleção cultural como os que investigam a ilusão de controle, já que demonstram a seleção de estimativas de controle e efeitos da consequência cultural no responder individual, bem como evidenciam a independência entre comportamento verbal e não verbal em uma situação na qual eventos ambientais são apresentados independentemente do responder / When people are exposed to situations with non-contingent events, they may develop an erroneous expectation of having comportamental control over the environment. This phenomenon is known as illusion of control. This study investigated the effects of cultural consequences on the estimate of control presented consensually by a trio of participants who has taken part in a task in which points were presented independently of what they made. 38 undergraduate students from a variety of courses participated in two experiments: in Experiment 1, four trios completed an experimental task, while in Experiment 2 there were two Cultures involving replacement of participants. Two activities characterized a complete cycle: (a) first of all, a basic individuak task, in which points were presented on the computer screen in a multiple schedule with variable time and extinction components (mult VT EXT). Bellow the points counter, there was a retangle manipulated by the participants by responses on the space bar of a keyborad. The retangles colour changed depending on the schedule component. (b) Then, after completing the computer task, participants consensually answered a question about the control they had in the production of points in a scale from low control (0) to high control (10). Cultural consequences were presented depending on the estimate of control and on the manipulated condition. In condition A, the consequence was presented contingent to estimates of control from 7 to 10; while in condition B the cultural consequence was contingent to estimates from 0 to 3. The results contribute to studies about cultural selection and illusion of control, since they have showed the selection of estimates of control and effects of cultural consequence on individual responding as well as evidence the independency of verbal and non verbal behavior in situations in which environmental events are presented non-contigently

Emergency Medical Services First Responder Certification Level's Impact on Ambulance Scene Times

Price, Devin Todd 01 January 2018 (has links)
The foundation of modern-day emergency medical service (EMS) systems began in 1966, based on hospital medical care. Demand for evidence to support prehospital practices that have been in existence for the past half-century has continued to grow; yet, researchers have not adequately explored the relationship between the medical certification level of emergency first responders and the amount of time an ambulance spends on the scene. The purpose of this quantitative study was to examine and compare ambulance scene times for emergency responses when basic life support (BLS) certified first responders or advanced life support (ALS) first responders are first on the scene, and whether the level of first responder training reduces the time spent on the scene by a paramedic ambulance. A final research question dealt with whether there is a relationship between how long the first responder is on the scene and the amount of time an ambulance spends at the scene of an emergency. The publicly available archival data used for the study were from a community that had BLS and ALS first responders. Data analysis involved t-tests of the hypotheses for the first 2 research questions and a linear regression analysis of the hypotheses for the third research question. The findings showed that there is a clear difference in ambulance scene times based on the certification level of the first responders. Advanced life support first responders significantly reduced the scene time of ambulances when they arrived at the scene prior to the ambulance. Positive social change could result from this study if understanding the impact that ALS first responders have on ambulance scene times leads EMS planning managers to deploy resources more strategically, thus improving the efficiency of the public safety system and saving lives.

Effects of Police-Mental Health Collaborative Services on Calls, Arrests, and Emergency Hospitalizations

Zauhar, Sean Russel-Jacque 01 January 2019 (has links)
With the increasing amount of police calls involving persons experiencing a mental health crisis (PICs), agencies are looking for ways to reduce the overuse of emergency services and criminal confinement. Police-mental health collaborative (PMHC) programs were developed to utilize the expertise of both mental health and law enforcement practitioners to provide immediate linkage to psychiatric services in an effort to prevent unnecessary involvement in the criminal justice system. The theoretical framework for this study was built on the sequential intercept model (SIM) along with the theories of social network and social support. The SIM identifies 5 key points where PICs can be diverted away from the criminal justice system. PMHC programs fall within the first intercept where persons with mental illness can be diverted at their first initial contact with law enforcement. Limited empirical research exists that show PMHC programs are reaching their intended objectives. The purpose of this quantitative study was to determine the effect of PMHC services on the likelihood that PICs will have future mental health calls (MHCs), arrests, and emergency hospitalizations (EHPs). Archival data from 1 midwestern police agency and online public court records was used in the analysis. The study employed OLS and logistic regression techniques, which revealed no statistically significant relationships between the PMHC interventions and the likelihood of future MHCs, arrests, and EHPs. However, significance was achieved for several covariates including transient status, prior history of MHCs, arrests, and EHPs. These findings will contribute to positive social change by informing policymakers and practitioners on best practices in community mental health crisis response.

The use of weights to account for non-response and drop-out

Höfler, Michael, Pfister, Hildegard, Lieb, Roselind, Wittchen, Hans-Ulrich 19 February 2013 (has links) (PDF)
Background: Empirical studies in psychiatric research and other fields often show substantially high refusal and drop-out rates. Non-participation and drop-out may introduce a bias whose magnitude depends on how strongly its determinants are related to the respective parameter of interest. Methods: When most information is missing, the standard approach is to estimate each respondent’s probability of participating and assign each respondent a weight that is inversely proportional to this probability. This paper contains a review of the major ideas and principles regarding the computation of statistical weights and the analysis of weighted data. Results: A short software review for weighted data is provided and the use of statistical weights is illustrated through data from the EDSP (Early Developmental Stages of Psychopathology) Study. The results show that disregarding different sampling and response probabilities can have a major impact on estimated odds ratios. Conclusions: The benefit of using statistical weights in reducing sampling bias should be balanced against increased variances in the weighted parameter estimates.

Assessing Educators’ School Safety and Security Preparedness at a New Jersey K-12 Nonpublic School

Rinaldi, Ronald P. 01 January 2016 (has links)
School shootings and emergencies have created the need for educators to be proficient in emergency response procedures; yet they do not always receive the requisite training. The lack of an established delineated training program for New Jersey, kindergarten to Grade 12 institutions has created a situation where educator preparedness varies immensely at schools. Numerous national events of targeted school violence have exemplified the need for quick and proper responses by educators to mitigate the tragic results until first responders arrive. The purpose and goal of this study was to assess educators’ perceptions and to determine the best practices in creating a comprehensive safety and security training program to prepare educators for school crises in order to offer a model for stakeholders to follow or gain ideas to improve their institution’s specific school safety and security emergency plans. Guided by the U.S. Department of Education’s best practices in developing high-quality school safety plans, this study analyzed the perceptions of 60 educators in one New Jersey kindergarten to Grade 12 school on the effectiveness of training. A mixed-methods approach, using a survey questionnaire and interviews, measured changes in the perceptions of these educators after the 15-week program. Data results included a revelation of the implementation of a comprehensive school safety and security plan with related training program resulted in a statistically significant increase in the perceptions of educators’ knowledge and abilities to respond effectively to school targeted violence and emergencies. These findings support the concept that best practices in the field of school safety and security management include appropriate and comprehensive school safety and security plans and training for educators to combat and mitigate school targeted violence and emergent events.

Stigma Reduction and Resiliency Training for First Responders (SRRT-FR): A Feasibility and Initial Efficacy Evaluation

Nicholson, Thalia P. 01 August 2024 (has links) (PDF)
First responders, especially law enforcement, frequently encounter individuals experiencing substance use concerns. Previous research has documented that a greater understanding of substance use disorders promotes a decrease in stigmatizing perspectives. We present a novel approach to training law enforcement officers to improve their interactions with community members exhibiting substance use disorders, while also promoting their professional well-being. The present study sought to evaluate the feasibility and acceptability of the Stigma Reduction and Resiliency Training for First Responders (SRRT-FR) in a sample of law enforcement officers, as well as its efficacy in decreasing stigmatizing perspectives towards substance use disorders and increasing professional resiliency. One hundred and ten law enforcement officers participated in SRRT-FR and completed pre-, post- (n = 77), and four-month follow-up (n = 42) surveys that assessed their perceptions towards individuals with substance use disorders, as well as their well-being within their profession. Preliminary results suggest that SRRT-FR is feasible and acceptable amongst officers and may decrease some stigmatizing perspectives and increase resiliency. The findings warrant replication with larger sample sizes and randomized controlled trials involving law enforcement officers, as well as other first responders.
