RESUMEN

Background: The COVID-19 pandemic has disproportionately impacted rural and under-resourced urban communities in Kansas. The state's response to COVID-19 has relied on a highly decentralized and underfunded public health system, with 100 local health departments in the state, few of which had prior experience engaging local community coalitions in a coordinated response to a public health crisis. Methods: To improve the capacity for local community-driven responses to COVID-19 and other public health needs, the University of Kansas Medical Center, in partnership with the Kansas Department of Health and Environment, will launch Communities Organizing to Promote Equity (COPE) in 20 counties across Kansas. COPE will establish Local Health Equity Action Teams (LHEATs), coalitions comprised of community members and service providers, who work with COPE-hired community health workers (CHWs) recruited to represent the diversity of the communities they serve. CHWs in each county are tasked with addressing unmet social needs of residents and supporting their county's LHEAT. LHEATs are charged with implementing strategies to improve social determinants of health in their county. Monthly, LHEATs and CHWs from all 20 counties will come together as part of a learning collaborative to share strategies, foster innovation, and engage in peer problem-solving. These efforts will be supported by a multilevel communications strategy that will increase awareness of COPE activities and resources at the local level and successes across the state. Our mixed methods evaluation design will assess the processes and impact of COPE activities as well as barriers and facilitators to implementation using aspects of both the Consolidated Framework for Implementation Research (CFIR) and Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) models. Discussion: This protocol is designed to expand community capacity to strategically partner with local public health and social service partners to prioritize and implement health equity efforts. COPE intentionally engages historically resilient communities and those living in underserved rural areas to inform pragmatic strategies to improve health equity.

RESUMEN

BACKGROUND: The COVID-19 pandemic added to the decades of evidence that public health institutions are routinely stretched beyond their capacity. Community health workers (CHWs) can be a crucial extension of public health resources to address health inequities, but systems to document CHW efforts are often fragmented and prone to unneeded redundancy, errors, and inefficiency. OBJECTIVE: We sought to develop a more efficient data collection system for recording the wide range of community-based efforts performed by CHWs. METHODS: The Communities Organizing to Promote Equity (COPE) project is an initiative to address health disparities across Kansas, in part, through the deployment of CHWs. Our team iteratively designed and refined the features of a novel data collection system for CHWs. Pilot tests with CHWs occurred over several months to ensure that the functionality supported their daily use. Following implementation of the database, procedures were set to sustain the collection of feedback from CHWs, community partners, and organizations with similar systems to continually modify the database to meet the needs of users. A continuous quality improvement process was conducted monthly to evaluate CHW performance; feedback was exchanged at team and individual levels regarding the continuous quality improvement results and opportunities for improvement. Further, a 15-item feedback survey was distributed to all 33 COPE CHWs and supervisors for assessing the feasibility of database features, accessibility, and overall satisfaction. RESULTS: At launch, the database had 60 active users in 20 counties. Documented client interactions begin with needs assessments (modified versions of the Arizona Self-sufficiency Matrix and PRAPARE [Protocol for Responding to and Assessing Patient Assets, Risks, and Experiences]) and continue with the longitudinal tracking of progress toward goals. A user-specific automated alerts-based dashboard displays clients needing follow-up and upcoming events. The database contains over 55,000 documented encounters across more than 5079 clients. Available resources from over 2500 community organizations have been documented. Survey data indicated that 84% (27/32) of the respondents considered the overall navigation of the database as very easy. The majority of the respondents indicated they were overall very satisfied (14/32, 44%) or satisfied (15/32, 48%) with the database. Open-ended responses indicated the database features, documentation of community organizations and visual confirmation of consent form and data storage on a Health Insurance Portability and Accountability Act-compliant record system, improved client engagement, enrollment processes, and identification of resources. CONCLUSIONS: Our database extends beyond conventional electronic medical records and provides flexibility for ever-changing needs. The COPE database provides real-world data on CHW accomplishments, thereby improving the uniformity of data collection to enhance monitoring and evaluation. This database can serve as a model for community-based documentation systems and be adapted for use in other community settings.

RESUMEN

The distribution of doctors in Brazil is marked by inequalities, hindering full and universal access to healthcare, fundamental to SUS. The Mais Médicos Program (PMM) reached peak of emergency provision in 2016, with 18,800 doctors allocated to 4,509 municipalities, one of the largest interventions of its type. A rapid systematic review was carried out to gather evidence of the Program's impacts on primary healthcare and on the assisted population's health. 570 studies were extracted and the final selection included 32 articles. Regarding the Program's effects, there was a rapid expansion in primary healthcare coverage, an improvement in comprehensiveness and humanization of healthcare, as well as significant impact on hospitalizations for primary healthcare sensitive conditions, which resulted in an approximate reduction of 23 thousand hospitalizations throughout three years, saving R$30 million for SUS. Critical points that undermined the Program's potential impact were also identified: focus deviations; changes in priority criteria and undue replacement of hired doctors by PMM physicians, in addition to the disruption caused by the departure of 8,500 Cuban doctors in November 2018. It is estimated that the relaunch of the Mais Médicos Program, in 2023, especially based on existing evidence, will promote the continued progress of the Program.


La distribución de médicos en Brasil es desigual, lo que dificulta el acceso pleno y universal a la salud, fundamental para el SUS. El Programa Mais Médicos (PMM) alcanzó su pico en 2016, con 18.088 médicos asignados a 4.509 municipios, una de las mayores intervenciones de su tipo en el mondo. Se llevó a cabo una revisión sistemática rápida para recopilar evidencia de los efectos del programa de Atención Primaria de Salud (APS) y sus impactos en la salud de la población atendida. Se extrajeron 570 estudios y fueran seleccionados 32 artículos. Acerca de los efectos del Programa, hubo una rápida ampliación de cobertura en APS, mejora en la integralidad y humanización de la atención de salud, así como un impacto en las hospitalizaciones a lo largo de tres años, ahorrando R$30 millones para el SUS. Puntos críticos que socavaban el impacto potencial del Programa fueran identificados: desviaciones en el enfoque; cambios en criterios de prioridad y sustitución indebida de médicos, además del trastorno provocado por la salida de 8.500 médicos cubanos en noviembre de 2018. Se estima que el relanzamiento del Programa Mais Médicos en 2023, especialmente con base en la evidencia existente, promoverá el progreso continuo del Programa.

RESUMEN

BACKGROUND: It is unclear how the type of an atherosclerotic cardiovascular disease (ASCVD) event potentially influences patients' likelihood of smoking cessation. METHODS: Using 2013 to 2018 data from the US based National Cardiovascular Data Registry Practice Innovation and Clinical Excellence outpatient cardiac registry, we identified patients who were current smokers at a clinic visit and followed them over time for a subsequent ASCVD event. Self-reported smoking status was assessed at each consecutive visit and used to determine smoking cessation after each interim ASCVD event (myocardial infarction, percutaneous coronary intervention, coronary artery bypass graft, stroke/transient ischemic attack, peripheral artery disease). We constructed separate multivariable Cox models with nonproportional hazards to examine the association of each interim ASCVD event with smoking cessation, compared with not having an interim ASCVD event. We estimated the relative association of ASCVD event type with smoking cessation using contrast tests. Analyses were stratified by presence versus absence of ASCVD at baseline. RESULTS: Across 530 cardiology practices, we identified 1 933 283 current smokers (mean age 62±15, male 54%, ASCVD at baseline 50%). Among the 322 743 patients who had an interim ASCVD event and were still smoking, 41 336 (12.8%) quit smoking by their first subsequent clinic visit, which was higher among those with baseline ASCVD (13.4%) as compared with those without baseline ASCVD (11.5%). Each type of ASCVD event was associated with an increased likelihood of smoking. Patients who had an myocardial infarction, underwent coronary artery bypass graft (hazard ratio, 1.60 [95% CI, 1.55-1.65]), or had a stroke or transient ischemic attack were more likely to quit smoking as compared with those who underwent elective percutaneous coronary intervention or had a new diagnosis of peripheral artery disease (hazard ratio, 1.20 [95% CI, 1.17-1.22]). CONCLUSIONS: Only 13% of patients reported smoking cessation after an ASCVD event, with the type of event being associated with the likelihood of smoking cessation, prompting the need for patient-centered interventions.

RESUMEN

INTRODUCTION: Rural and under-resourced urban communities face unique challenges in addressing patients' social determinants of health needs (SDoH). Community health workers (CHWs) can support patients experiencing social needs, yet little is known about how rural and under-resourced primary care clinics are screening for SDoH or utilizing CHWs. METHODS: Interviews were conducted with primary care clinic providers and managers across a geographically large and predominately rural state to assess screening practices for SDoH and related community resources, and perspectives on using CHWs to address SDoH. Interviews were conducted by phone, recorded, and transcribed. Data were analyzed using thematic analysis. We completed interviews with 27 respondents (12 providers and 15 clinic managers) at 26 clinics. RESULTS: Twelve (46.1%) clinics had a standardized process for capturing SDoH, but this was primarily limited to Medicare wellness visits. Staffing and time were identified as barriers to proper SDoH screening. Lack of transportation and affordable medication were the most cited SDoH. While respondents were all aware of CHWs, only 8 (30.8%) included a CHW on their care team. Perceived barriers to engaging CHWs included cost, space, and availability of qualified CHWs. Perceived benefits of engaging CHWs in their practice were: assisting patients with navigating resources and programs, relieving clinical staff of non-medical tasks, and bridging language barriers. CONCLUSIONS: Rural and under-resourced primary care clinics need help in identifying and addressing SDoH. CHWs could play an important part in addressing social needs and promoting preventive care if financial constraints could be addressed and local CHWs could be trained.

RESUMEN

BACKGROUND: Critical limb ischemia (CLI), the most severe form of peripheral artery disease, is associated with pain, poor wound healing, high rates of amputation, and mortality (>20% at 1 year). Little is known about the processes of care, patients' preferences, or outcomes, as seen from patients' perspectives. The SCOPE-CLI study was co-designed with patients to holistically document patient characteristics, treatment preferences, patterns of care, and patient-centered outcomes for CLI. METHODS: This 11-center prospective observational registry will enroll and interview 816 patients from multispecialty, interdisciplinary vascular centers in the United States and Australia. Patients will be followed up at 1, 2, 6, and 12 months regarding their psychosocial factors and health status. Hospitalizations, interventions, and outcomes will be captured for 12 months with vital status extending to 5 years. Pilot data were collected between January and July of 2021 from 3 centers. RESULTS: A total of 70 patients have been enrolled. The mean age was 68.4 ± 11.3 years, 31.4% were female, and 20.0% were African American. CONCLUSIONS: SCOPE-CLI is uniquely co-designed with patients who have CLI to capture the care experiences, treatment preferences, and health status outcomes of this vulnerable population and will provide much needed information to understand and address gaps in the quality of CLI care and outcomes.ClinicalTrials.gov identifier (NCT Number): NCT04710563 https://clinicaltrials.gov/ct2/show/NCT04710563.

RESUMEN

RESUMO Existe ampla evidência que a contenção da pandemia de Covid-19 requer vigilância sindrômica e isolamento de casos suspeitos/confirmados. É essencial a disponibilidade de testes diagnósticos no Sistema Único de Saúde, que poderia ser facilitada pela soberania nacional no desenvolvimento e produção, considerando-se a alta demanda/escassez no mercado internacional. Este estudo identificou as etapas da pesquisa translacional de testes diagnósticos para Covid-19 no Brasil, verificando sua distribuição geográfica, entre outros indicadores. Estudo transversal, exploratório, partindo de banco público com 789 projetos de Pesquisa, Desenvolvimento e Inovação (PD&I) em Covid-19, complementado com outras buscas, inclusive no CVLattes dos pesquisadores. No banco, havia 89 projetos de testes diagnósticos. Em 45 casos, foi possível obter informações complementares para classificá-los conforme as etapas da pesquisa translacional. Identificaram-se 15 inovações que atingiram o estágio T3, ou seja, tiveram seus produtos incorporados em protocolos clínicos na atenção à saúde, mesmo considerando-se as profundas restrições orçamentárias em PD&I. O Brasil possui potencial de desenvolvimento e implementação de produtos tecnológicos na área de testes de diagnóstico para Sars-CoV-2. Políticas públicas de PD&I em saúde necessitam ser priorizadas para ampliação de cooperações nacionais e internacionais, a fim de promover efetiva autonomia nacional na vigilância sindrômica e à saúde da população.


ABSTRACT There is much evidence suggesting that mitigating the COVID-19 pandemic requires syndromic surveillance and isolation of suspected/confirmed cases. The availability of diagnostic tests in the Brazilian Unified Health System (SUS) is essential, which could be facilitated by national sovereignty in development and production, considering the high demand/lack of supply in the international market. This study identified the stages of translational research into diagnostic tests for COVID-19 in Brazil, verifying their geographic distribution, among other indicators. A cross-sectional, exploratory study based on a public database with 789 Research, Development, and Innovation (RD&I) projects regarding COVID-19, complemented by other searches, including the researchers' curricula (CVLattes). There were 89 diagnostic test projects in the database. In 45 cases, it was possible to obtain additional information to classify them according to the translational research stages. Fifteen innovations that reached the T3 stage were identified, with their products incorporated into clinical protocols in healthcare, even considering the deep budget restrictions in RD&I. Brazil has the potential to develop and implement technological products in the field of diagnostic tests for SARS-CoV-2. Public health RD&I policies need to be prioritized to expand national and international cooperation to promote effective national autonomy in syndromic surveillance and population health.

RESUMEN

Importance: The management of coronary disease epitomizes the call to better engage patients in shared medical decision-making. Myocardial perfusion imaging (MPI) is the foundation of diagnosis, risk stratification, and subsequent therapy; however, MPI reports are currently interpretable by specialists but not patients. Objective: To design and test a patient-centered report for stress MPI test results. Design, Setting, and Participants: This qualitative study of outpatients who underwent an MPI stress test and clinicians used a mixed methods approach. Phase 1 (December 2018 to July 2019) used qualitative methods to design a patient-centered reporting tool, with 5 focus groups with 36 patients and 2 focus groups with 27 clinicians. Phase 2 (June to September 2019) consisted of pilot testing the reporting tool with feedback from a structured survey given to patients who received MPI reports before and after implementing the tool. Main Outcomes and Measures: Key themes around patient experiences with the current MPI reporting and their desire for a more useful report were identified, which led to a sample reporting tool after serial iterations with feedback. Differences in patient knowledge and engagement were assessed between patients before and after implementation of the new reporting tool using χ2 tests. Results: From patient focus groups (26 patients; mean [SD] age, 66.3 [9.6] years, 9 [35%] women), 3 themes on the inadequacies of current MPI reporting were identified: (1) inconsistent delivery of results, (2) use of medical jargon, and (3) unclear posttest course. We identified 5 themes for a more patient-centered MPI report: desire for written information, discussion of the report with medical personnel, presentation of results in simple language with use of visual graphics, comparisons with normal results, and personalized risk estimates. In a pilot survey with 123 patients split into a pre-implementation group (69 patients; mean [SD] age, 68.2 [8.5] years; 27 [51%] women) and a postimplementation group (54 patients; mean [SD] age, 66.4 [8.7] years; 30 [56%] women), the patient-centered report led to more patients reading the entire report (45 [83%] vs 46 [67%]; P = .04) and improved knowledge of future risk of cardiac events (41 [76%] vs 20 [29%]; P < .001). There was also a numerically higher percentage of patients who found the report easy to read (45 [83%] vs 44 [68%]; P = .05) and understand (42 [78%] vs 43 [66%]; P = .16), although these results were not statistically significant. Conclusions and Relevance: This study identified key elements of a patient-centered report design for stress MPI test results, which improved patient engagement and knowledge. These preliminary data support further implementation and study of a more patient-centered MPI report.

RESUMEN

BACKGROUND: Physical exercise is a health promotion factor regulating gene expression and causing changes in phenotype, varying according to exercise type and intensity. Acute strenuous exercise in sedentary individuals appears to induce different transcriptional networks in response to stress caused by exercise. The objective of this research was to investigate the transcriptional profile of strenuous experimental exercise. METHODOLOGY: RNA-Seq was performed with Rattus norvegicus soleus muscle, submitted to strenuous physical exercise on a treadmill with an initial velocity of 0.5 km/h and increments of 0.2 km/h at every 3 min until animal exhaustion. Twenty four hours post-physical exercise, RNA-seq protocols were performed with coverage of 30 million reads per sample, 100 pb read length, paired-end, with a list of counts totaling 12816 genes. RESULTS: Eighty differentially expressed genes (61 down-regulated and 19 up-regulated) were obtained. Reactome and KEGG database searches revealed the most significant pathways, for down-regulated gene set, were: PI3K-Akt signaling pathway, RAF-MAP kinase, P2Y receptors and Signaling by Erbb2. Results suggest PI3K-AKT pathway inactivation by Hbegf, Fgf1 and Fgr3 receptor regulation, leading to inhibition of cell proliferation and increased apoptosis. Cell signaling transcription networks were found in transcriptome. Results suggest some metabolic pathways which indicate the conditioning situation of strenuous exercise induced genes encoding apoptotic and autophagy factors, indicating cellular stress. CONCLUSION: Down-regulated networks showed cell transduction and signaling pathways, with possible inhibition of cellular proliferation and cell degeneration. These findings reveal transitory and dynamic process in cell signaling transcription networks in skeletal muscle after acute strenuous exercise.

RESUMEN

Patients with peripheral artery disease (PAD) face a range of treatment options to improve survival and quality of life. An evidence-based shared decision-making tool (brochure, website, and recorded patient vignettes) for patients with new or worsening claudication symptoms was created using mixed methods and following the International Patient Decision Aids Standards (IPDAS) criteria. We reviewed literature and collected qualitative input from patients (n = 28) and clinicians (n = 34) to identify decisional needs, barriers, outcomes, knowledge, and preferences related to claudication treatment, along with input on implementation logistics from 59 patients and 27 clinicians. A prototype decision aid was developed and tested through a survey administered to 20 patients with PAD and 23 clinicians. Patients identified invasive treatment options (endovascular or surgical revascularization), non-invasive treatments (supervised exercise therapy, claudication medications), and combinations of these as key decisions. A total of 65% of clinicians thought the brochure would be useful for medical decision-making, an additional 30% with suggested improvements. For patients, those percentages were 75% and 25%, respectively. For the website, 76.5% of clinicians and 85.7% of patients thought it would be useful; an additional 17.6% of clinicians and 14.3% of patients thought it would be useful, with improvements. Suggestions were incorporated in the final version. The first prototype was well-received among patients and clinicians. The next step is to implement the tool in a PAD specialty care setting to evaluate its impact on patient knowledge, engagement, and decisional quality. ClinicalTrials.gov Identifier: NCT03190382.

RESUMEN

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has spread throughout more than 160 countries, infecting millions of people worldwide. To address this health emergency, countries have organized the flow of production and innovation to reduce the impact on health. This article shows the response of the Brazilian scientific community to meet the urgent needs of the public unified health system [SUS], aiming to guarantee universal access to an estimated population of 211 million. By December 2020, Brazil had recorded more than six million cases and approximately 175,000 deaths. METHODS: We collected data on research, development and innovation projects carried out by 114 public universities (plus Oswaldo Cruz Foundation [Fiocruz] and Butantan Institute), as reported on their websites. Additionally, we examined the studies on COVID-19 approved by the National Comission for Research Ethics, as well as those reported on the Ministry of Education website as of May 15, 2020. RESULTS: The 789 identified projects were classified according to research categories as follows: development and innovation (n = 280), other types of projects (n = 226), epidemiologic research (n = 211), and basic research on disease mechanisms (n = 72). Most proposals focused on the development and innovation of personal protective equipment, medical devices, diagnostic tests, medicines and vaccines, which were rapidly identified as research priorities by the scientific community. Some promising results have been observed from phase III vaccine trials, one of which is conducted in partnership with Oxford University and another of which is performed with Sinovac Biotech. Both trials involve thousands of volunteers in their Brazilian arms and include technology transfer agreements with Fiocruz and the Butantan Institute, respectively. These vaccines proved to be safe and effective and were immediately licensed for emergency use. The provision of doses for the public health system, and vaccination, started on January 17, 2021. CONCLUSIONS: The mobilized Brazilian scientific community has generated comprehensive research, development and innovation proposals to meet the most urgent needs. It is important to emphasize that this response was only possible due to decades of investment in research, development and innovation in Brazil. We need to reinforce and protect the Brazilian science, technology and innovation system from austerity policies that disregard health and knowledge as crucial investments for Brazilian society, in line with the constitutional right of universal health access and universal health coverage.

RESUMEN

RESUMO A pesquisa translacional envolve a interface entre a pesquisa básica e a clínica médica com o intuito de gerar produtos ou processos inovadores para introduzi-los nos protocolos clínicos e nos sistemas de saúde. O objetivo desse ensaio foi apresentar uma visão geral dos avanços da transcriptômica, subsidiados pela disponibilidade e utilização das novas tecnologias da informação e biologia molecular. Na busca pelo diagnóstico preciso e menos invasivo, testes transcriptômicos utilizam assinaturas de expressão gênica visando detectar doenças neurodegenerativas (Parkinson e Alzheimer), autoimunes (lúpus eritematoso sistêmico, granulomatose de Wegener), insuficiência cardíaca, autismo e câncer (de mama, colorretal, hepático e de pulmão). No sistema de saúde inglês as diretrizes clínicas incorporam oito testes transcriptômicos, todos com foco no câncer. No Brasil testes genômicos com base nas sequências de DNA são regulamentados para diagnosticar anomalias congênitas, tanto no Sistema Único de Saúde, como na saúde suplementar, mas os testes moleculares não avançaram no âmbito da transcriptômica diagnóstica. O sistema de saúde brasileiro deveria ir além dos testes de análise genômica e iniciar o processo de regulamentação das tecnologias transcriptômicas de diagnóstico. No futuro, testes diagnósticos avaliando múltiplos perfis de expressão gênica podem se transformar em exames de rotina numa forma de triagem molecular.


ABSTRACT Translational research involves the interface between basic research and medical practice in order to generate innovative products or processes to introduce them into clinical protocols and health systems. The objective of this essay was to present an overview of transcriptomic advances, subsidized by the availability and use of new information technologies and molecular biology. In the search for accurate and less invasive diagnosis, transcriptomic tests use gene expression signatures to detect neurodegenerative diseases (Parkinson and Alzheimer), autoimmune (systemic lupus erythematosus, Wegener's granulomatosis), heart failure, autism and cancer (breast, colorectal, hepatic and lung). In the English health system the clinical guidelines incorporate eight transcriptomic tests, all with a focus on cancer. In Brazil genomic tests based on DNA sequences are regulated to diagnose congenital anomalies both in the Unified Health System and in supplementary health, but the molecular tests have not advanced in the scope of the diagnostic transcriptomics. The Brazilian health system should go beyond the tests of genomic analysis and begin the process of regulation of transcriptomic diagnostic technologies. In the future, diagnostic tests evaluating multiple gene expression profiles may become routine exams in a form of molecular screening.

RESUMEN

Background Smoking is the most important risk factor for peripheral artery disease ( PAD ). Smoking cessation is key in PAD management. We aimed to examine smoking rates and smoking cessation interventions offered to patients with PAD consulting a vascular specialty clinic; and assess changes in smoking behavior over the year following initial visit. Methods and Results A total of 1272 patients with PAD and new or worsening claudication were enrolled at 16 vascular specialty clinics (2011-2015, PORTRAIT (Patient-Centered Outcomes Related to Treatment Practices in Peripheral Arterial Disease: Investigating Trajectories) registry). Interviews collected smoking status and cessation interventions at baseline, 3, 6, and 12 months. Among smokers, transition state models analyzed smoking transitions at each time point and identified factors associated with quitting and relapse. On presentation, 474 (37.3%) patients were active, 660 (51.9%) former, and 138 (10.8%) never smokers. Among active smokers, only 16% were referred to cessation counseling and 11% were prescribed pharmacologic treatment. At 3 months, the probability of quitting smoking was 21%; among those continuing to smoke at 3 months, the probability of quitting during the next 9 months varied between 11% and 12% ( P<0.001). The probability of relapse among initial quitters was 36%. At 12 months, 72% of all smokers continued to smoke. Conclusions More than one third of patients with claudication consulting a PAD provider are active smokers and few received evidence-based cessation interventions. Patients appear to be most likely to quit early in their treatment course, but many quickly relapse and 72% of all patients smoking at baseline are still smoking at 12 months. Better strategies are needed to provide continuous cessation support. Clinical Trial Registration URL : https://www.clinicaltrials.gov . Unique identifier: NCT 01419080.

RESUMEN

Regular exercise is an exogenous factor of gene regulation with numerous health benefits. The study aimed to evaluate human genes linked to physical exercise in an 'omic scale, addressing biological questions to the generated database. Three literature databases were searched with the terms 'exercise', 'fitness', 'physical activity', 'genetics' and 'gene expression'. For additional references, papers were scrutinized and a text-mining tool was used. Papers linking genes to exercise in humans through microarray, RNA-Seq, RT-PCR and genotyping studies were included. Genes were extracted from the collected literature, together with information on exercise protocol, experimental design, gender, age, number of individuals, analytical method, fold change and statistical data. The 'omic scale dataset was characterized and evaluated with bioinformatics tools searching for gene expression patterns, functional meaning and gene clusters. As a result, a physical exercise-related human gene compendium was created, with data from 58 scientific papers and 5.147 genes functionally correlated with 17 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. While 50.9% of the gene set was up-regulated, 41.9% was down-regulated. 743 up- and 530 down-regulated clusters were found, some connected by regulatory networks. To summarize, up- and down-regulation was encountered, with a wide genomic distribution of the gene set and up- and down-regulated clusters possibly assembled by functional gene evolution. Physical exercise elicits a widespread response in gene expression.

RESUMEN

Introduction: Prevalence of cigarette smoking is highest among American Indians, yet few culturally appropriate smoking cessation programs have yet been developed and tested for multi-tribal American Indian adult populations. This study examined implementation of the All Nations Breath of Life culturally tailored smoking cessation program in multi-tribal urban and suburban American Indian communities in seven locations across five states (N = 312). Methods: This single-arm study used community-based participatory research to conduct a 12-week intervention whose primary purpose was to curb commercial tobacco use among American Indians. Participants were followed through month 6 in person and month 12 via telephone. The primary outcome was continuous abstinence from recreational cigarette smoking at 6 months post-baseline, verified through voluntary provision of salivary cotinine levels. Results: At program completion (12 weeks post-baseline), 53.3% of program completers remained abstinent; labeling those lost to follow-up as smokers resulted in a 41.4% quit rate. At 6 months post-baseline (primary endpoint), 31.1% of retained participants quit smoking (p < .0001 compared to the highest quit rates among multi-tribal populations reported in the literature, 7%); final quit rate was 22.1% labeling those lost to follow-up as smokers (p = .002). Retention rate at endpoint was 71.2%. 12-month follow-up was attempted with all participants and had a retention rate of 49.0%. Of those participants reached, 34.0% were smoke-free. Conclusions: All Nations Breath of Life shows promise as a smoking cessation program for multi-tribal urban American Indian communities. It can be successfully implemented in a variety of urban settings. Implications: This is the first large feasibility study of a culturally tailored smoking cessation program for American Indians with good cessation and retention rates in a multi-tribal urban American Indian population. It shows that All Nations Breath of Life can be implemented in multiple urban settings across five states. To our knowledge, this is the first program of its kind to be implemented across multiple heterogeneous urban locations and to include salivary cotinine testing for verification of self-report data across these locations.

RESUMEN

OBJECTIVE: The purpose of this study was to examine knowledge, awareness, and support for campus smoke-free policies. PARTICIPANTS: 1,256 American Indian tribal college students from three tribal colleges in the Midwest and Northern Plains. METHODS: Data are from an observational cross-sectional study of American Indian tribal college students, collected through a web-based survey. RESULTS: Only 40% of tribal college students reported not being exposed to second hand smoke in the past 7 days. A majority of nonsmokers (66%) agreed or strongly agreed with having a smoke-free campus, while 34.2% of smokers also agreed or strongly agreed. Overall, more than a third (36.6%) of tribal college students were not aware of their campus smoking policies. CONCLUSIONS: Tribal campuses serving American Indian students have been much slower in adopting smoke-free campus policies. Our findings show that tribal college students would support a smoke-free campus policy.

RESUMEN

The main objective of this research was to analyze the climate data for the host cities of the soccer World Cup held in Brazil in June and July 2014. A great deal of criticism was expressed about the Brazilian climate in the national and international press and media in the run-up to the competition, suggesting that the air temperature and relative air humidity would be the main adversaries of the soccer teams, especially those from Europe, during the competition. An analysis of the weather was done at the places and times of each of the 64 matches held. A human thermal comfort index was calculated (discomfort index (DI)) for each of the matches in order to discover the real climatic conditions in the host cities during the 2014 World Cup and their potential influence on the teams and human comfort in general. During the 2014 World Cup, only two matches were played at temperatures above 30 °C, representing a negligible percentage of the total number of matches. The air temperature for over half the matches (53%) was 20-25 °C. The results showed the air temperature and relative humidity data analyzed here both individually and in the form of an index indicate that the World Cup held in Brazil in 2014 did not put any of the players at risk due to extreme heat.

RESUMEN

RESUMO Introdução: Novos estudos de regulação gênica do exercício físico por meio de técnicas pós-genômicas em ensaios de resistência (endurance) e força caracterizam a transcriptômica do exercício físico. Entre os genes afetados, destacamos a via da proteína quinase ativada por AMP (AMPK), cuja ativação ocorre durante o exercício como resultado das alterações dos níveis de fosfato energético da fibra muscular. Objetivo: Avaliar a via de sinalização da AMPK por revisão sistemática da expressão de genes e análise in silico. Método: Foi efetuada uma revisão sistemática para avaliar a regulação gênica da via de sinalização AMPK, caracterizando os genes estudados na literatura, as variações de regulação obtidas, na forma de fold change e tipos de exercício usados. Resultados: A via de sinalização AMPK mostrou 133 genes no repositório KEGG (Kyoto Encyclopedia of Genes and Genomes), os quais foram confrontados com a revisão sistemática da literatura, totalizando 65 genes. Dezessete genes apresentaram UR e 24 mostraram DR com relação ao seu respectivo controle. Além destes, 20 genes estavam presentes nos trabalhos, apresentando tanto UR e DR e quatro genes não apresentaram dados de regulação. Verificou-se regulação específica em função do tipo de exercício efetuado. Discussão: Dos 133 genes da via AMPK, 48,8% foram amostrados nos trabalhos revisados, indicando que uma parte significativa da via é regulada pelo exercício. O estudo apresentou a regulação gênica básica de dois mecanismos para a recuperação energética, a biogênese mitocondrial e o bloqueio da gliconeogênese. Conclusão: Este trabalho mostrou que o exercício atua ativamente na via de sinalização da AMPK, na importância da regulação via PGC-1α e no papel de outros genes, regulando a expressão de mais da metade dos genes amostrados.


ABSTRACT Introduction: New studies of gene regulation by physical exercise through post-genomic techniques in endurance and strength tests characterize the physical exercise transcriptomics. Among the affected genes, we highlight the AMP-activated protein kinase (AMPK) pathway, the activation of which occurs during exercise because of changes in muscle fiber energetic phosphate levels. Objective: To evaluate the AMPK signaling pathway by systematic review of gene expression and in silico analysis. Method: A systematic review was performed in order to assess the gene regulation of AMPK signaling pathway, characterizing the genes studied in the literature, regulation variations obtained in the form of fold change, and types of exercise performed. Results: The AMPK signaling pathway showed 133 genes in the KEGG repository (Kyoto Encyclopedia of Genes and Genomes), which were compared with the systematic review of the literature, totaling 65 genes. Seventeen genes presented UR and 24 showed DR in relation to their respective control. In addition to these, 20 genes were present in the literature, presenting both UR and DR and four genes showed no regulatory data. Specific regulation was verified according to the type of exercises performed. Discussion: Of the 133 genes of the AMPK pathway, 48.8% were sampled in the revised studies indicating that a significant part of the pathway is regulated by exercise. The study presented the basic gene regulation of two mechanisms for energy recovery, mitochondrial biogenesis, and gluconeogenesis blockade. Conclusion: This work showed that the exercise actively works in the AMPK signaling pathway, in the importance of regulation via PGC-1α and in the role of other genes, regulating the expression of more than half of the genes sampled.

RESUMEN

Balanced two-arm designs are more powerful than unbalanced designs and, consequently, Bayesian adaptive designs (BADs) are less powerful. However, when considering other subject- or community-focused design characteristics, fixed two-arm designs can be suboptimal. We use a novel approach to identify the best two-arm study design, taking into consideration both the statistical perspective and the community's perception. Data envelopment analysis (DEA) was used to estimate the relative performance of competing designs in the presence of multiple optimality criteria. The two-arm fixed design has enough deficiencies in subject- and community-specific benefit to make it the least favorable study design.

RESUMEN

The popularity and usage of social media networks or SNS (social networking sites) among American Internet users age 50 and over doubled between 2009 and 2010 and has steadily climbed. Part of this increased access may be the result of older adults who are living with a chronic disease and are reaching out for online support. Colorectal cancer (CRC) risk is among those concerns, particularly among middle-age and older minority populations where disparities exist. This exploratory study investigates information seeking behavior related to cancer factors (e.g. testing for colon cancer, cancer fatalism) and current social media usage among racial and ethnic minority groups (African American and Latinos) and Whites age 50 and older. The secondary data from the 2012 Health Information National Trends Survey (HINTS) was analyzed to compare these populations. Results show that African Americans and Latinos were only slightly more likely to use social network sites to seek out cancer information compared to Whites. However, Whites were more likely to use the Internet to seek health information compared to African Americans and Latinos. In this sample, Whites were also more likely to be informed by a physician about CRC testing (p <.01). Whites were also more fatalistic about CRC (p<.001) and more likely to have self-reported receiving a positive diagnosis (p <.001). Implications of this study suggest that use of both traditional health information sources (physician) and the Internet (social media networks, Internet sites) have increased among older Americans and can serve as critical channels for cancer information and education.
