Experimental Protocols Used to Mimic Gastrointestinal Protein Digestion: A Systematic Review.

Bioactive peptides derived from native proteins modulate physiological processes in the metabolic pathways. Given that multiple protocols in the literature mimic the digestion of dietary components, gathering studies that use such models directed at protein digestion processes is critical. This systematic review aimed to gather evidence that adopted adequate experimental models to simulate human protein digestion. The databases searched were PubMed, Web of Science, ScienceDirect, Embase, Virtual Health Library, and Scopus. A total of 1985 articles were found, resulting in 20 eligible in vitro studies. The Office of Health Assessment and Translation was used to evaluate methodological quality. Seven studies used plant-based protein sources, twelve used animal protein sources, and one used both. The duration of the oral phase varied, although 60% of the studies employed a protein digestion period of 120 min. Amylase, pepsin, and pancreatin enzymes were utilized in 40% of the studies, with pH levels of 7, 3, and 7, respectively, during the oral, gastric, and intestinal phases. The INFOGEST harmonized static model was adopted by 65% of the studies; INFOGEST is the most effective model for simulating gastrointestinal protein processes in humans and can be used to answer several research questions because it describes experimental conditions close to the human physiological situation.

Association between sedentary behavior and Brain-Derived Neurotrophic Factor (BDNF) in children and adolescents: A protocol for systematic review and meta-analysis.

BACKGROUND: There is evidence in the literature suggesting that high time spent in sedentary behavior (SB) can reduce the Brain-Derived Neurotrophic Factor (BDNF) levels, an important neurotrophin that plays a role in modulating cognition, learning and memory. Children and adolescents usually spend many hours a day on SB, either sitting for a long time and/or using screen equipment. OBJECTIVE: The aim of this study is to describe a systematic review and meta-analysis protocol on the associations between SB and BDNF levels in children and adolescents. METHODS: This protocol is guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols and was published in the International Prospective Register of Systematic Reviews database (PROSPERO: CRD42023392246). The databases that will be searched are EMBASE, Scopus, ScienceDirect, Web of Science, SPORTDiscus, CINAHL, and PubMed. Cross-sectional and cohort studies conducted with children and adolescents (5 to 19 yr) that analyzed the association between SB and BDNF will be included in the systematic review. The characteristics of the studies, methodological aspects, and main results will be described. Then, the risk of bias (assessed by STROBE and Newcastle-Ottawa scales) and the level of evidence (assessed by the GRADE tool) from included studies will be evaluated. Sub-group analysis will also be performed. Two experienced reviewers will perform the studies selection, data extraction, and methodological quality assessment. CONCLUSION: This systematic review and meta-analysis will analyze the association between SB and BDNF in children and adolescents. The results will provide subsidies to better understand this relationship and will strengthen evidence-based practice for both health professionals and future researches.

Gamification as a health education strategy of adolescents at school: Protocol for a systematic review and meta-analysis.

The objective of the study is to present a systematic review and meta-analysis protocol for evaluating the effects of health education gamification-based interventions, on health parameters (food consumption, sleep quality and physical activity) of adolescent students. This protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42022373833). The search will be performed in the following databases: MEDLINE, Embase, Scopus, ERIC, ScienceDirect, Web of Science, Cochrane, LILACS, APA, and ADOLEC. Intervention studies (clinical trials - randomized or non-randomized) and quasi-experimental studies will be included. The risk of bias will be assessed using the Risk of Bias in Non-randomized Studies of Interventions tool for randomized controlled trials, non- randomized controlled trials and quasi-experimental trials. Two independent researchers will conduct all assessments, and any disagreements will be consulted with a third reviewer. Data analysis and synthesis will be analyzed using RevMan 5.4.1 software. We will conduct the study in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guideline. The review will summarize the current evidence on gamification health education changes in parameters related to the health of adolescents. Gamification has been used to verify the increase in adherence to healthy habits or the development of health-related skills, but there are still few results for the adolescent population. We expect that the systematic review could indicate strategies with gamification interventions and also determine how these strategies can improve health parameters of adolescent students, and they will be available as a reference for these interventions.

Associations of the consumption of unprocessed red meat and processed meat with the incidence of cardiovascular disease and mortality, and the dose-response relationship: A systematic review and meta-analysis of cohort studies.

OBJECTIVES: The aim of this study was to examine the associations of unprocessed red meat and processed meat consumption with cardiovascular disease (CVD) incidence and mortality, and the dose-response relationship. METHODS: Published literature was retrieved through a structured search of 10 electronic databases: MEDLINE/PubMed, Scopus, SciELO, LILACS, ScienceDirect, Web of Science, Cochrane (CENTRAL), WHOLIS, PAHO and Embase, without language or year of publication restrictions. In addition, we searched the references of published studies. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes: The PRISMA Statement. RESULTS: Twenty-one prospective cohort studies were included in the systematic review. The CVDs evaluated in the inserted studies were stroke, heart failure (HF) and coronary heart disease (CHD). Considering the heterogeneity found in the studies, for the meta-analysis, 9 articles were included. The results presented in the meta-analysis of the association of consumption of unprocessed red meat and CVD indicated that there was a significant association with total stroke incidence (RR 1.10; 95%; CI 1.01 to 1.19; p = 0.02). There was no association with Ischemic stroke incidence, nor CHD Mortality with consumption of unprocessed red meat. However, for Hemorrhagic Stroke Mortality the assessment in the consumption of unprocessed red meat showed an association of protection for women (RR 0.64; 95%; CI 0.45 to 0.91; p = 0.01). As for the results of the meta-analysis of the association between consumption of processed meat and CVD, they indicated that there was a significant association with total stroke incidence (RR 1.17; 95%; CI 1.08 to 1.26; p < 0.0001). There was no association with Ischemic stroke, nor with CHD Mortality with consumption of processed meat. Some studies that showed no association of risk, presented a significant linear trend dose response for the association of the consumption of unprocessed red meat (Bernstein et al. 2010; Nagao et al. 2012) or processed meat (Bernstein et al. 2012) and CVD. CONCLUSION: According to the results found in the meta-analysis, the consumption of unprocessed red meat and processed meat are associated with the incidence of stroke, however, no positive association was observed in relation to mortality from CVD. This systematic review and meta-analysis protocol was registered on the PROSPERO (number: CRD42019100914).

Environmental footprints of food consumption: Protocol for a systematic literature review.

Environmental footprints are indicators that can be used to estimate the impacts of diet on the environment. Since contemporary dietary practices are related to negative environmental impacts, this paper aims to describe a systematic review protocol to investigate the environmental footprints of food consumption by adults and elderly individuals worldwide. This protocol was developed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Search strategies and records of evidence searched in previously defined electronic databases will be defined. Original, population-based articles investigating the environmental footprints of food consumption by adults and the elderly will be included. Two independent reviewers will conduct the study selection and data extraction steps. Critical appraisal of the included studies will be based on the Newcastle-Ottawa Scale. For data synthesis, a narrative synthesis and, if possible, also a meta-analysis will be performed. The systematic review produced from this protocol will provide evidence for data synthesis of the environmental impact through environmental footprints of food consumption of the adult and elderly population from different territories and the footprint assessment tools used around the world. Therefore, it is a gap that needs to be filled because knowing these impacts will be important to inform the development of public policies that encourage healthy and sustainable food in the face of climate and epidemiological changes.

Effect of School-Based Food and Nutrition Education Interventions on the Food Consumption of Adolescents: A Systematic Review and Meta-Analysis.

The school is a favorable environment for the development of interventions to prevent obesity. The objective of this systematic review is to evaluate the effects of school-based food and nutrition education interventions on adolescent food consumption. The literature search was conducted on databases: MEDLINE/PubMed, Embase, Scopus, ERIC, Science Direct, Web of Science, Cochrane, LILACS, and ADOLEC. The following research strategies were focused on: population (adolescents), intervention (food and nutrition education), outcome (food consumption), and study design (clinical trial). The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement guidelines were followed and all stages of this review were performed by two researchers and, when necessary, a third researcher resolved discrepancies. Included studies are randomized clinical trials (RCT). A total of 24 articles were included for review and 11 articles in meta-analysis. In the evaluation of the general effects, there was a significant effect (mean difference (MD) for fruit consumption (MD = 0.09, CI 0.05, 0.14) in serving/day; and for vegetables (MD = 0.59, IC 0.15, 1.03) at times/week. In the consumption of FV (fruits and vegetables), there was no significant effect (standardized mean difference (SMD) of interventions in their consumption (SMD = 0.00, 95% C1 -0.11, 0.11). The evidence available in this review and meta-analysis concludes that food and nutrition education interventions in schools presented favorable results in the food consumption of adolescents. Registered on the PROSPERO database (CRD42019116520).

Abstract Background The inclusion of physical education professionals in primary care is relevant due to work related to health promotion, but some challenges are presented in the literature as barriers to professional performance. Objective This study aimed to review in the literature the challenges faced by physical education professionals who work in the extended centers for family health and primary care (NASF-AB). Method A search using the terms "physical education" and "family health support centers" was performed in the LILACS and SciELO databases. The inclusion criteria were: be an original article, be published in the Portuguese language, be published from 2008 onwards, and have assessed the role of physical education professionals in the NASF-AB. Results From 45 studies identified in the initial search, six met the inclusion criteria. In addition to these, two other articles were identified in the references, resulting in eight articles included in the review. Among the several challenges reported, the most frequent ones in the different studies were the lack of physical and material infrastructure, the distance between academic formation and the collective health area, and also professional instability. Conclusion Although some of the challenges reported do not depend solely on the physical education professional to be solved, the findings of this review already provide important information for future professionals who wish to work in NASF-AB to prepare themselves more objectively and perform an efficient and quality work.

Can polyphenols improve the gut health status in pre-clinical study with diet-induced obesity?: A protocol for systematic review and/or meta-analysis.

INTRODUCTION: Obesity is characterized as a low-grade inflammation that impairs physiological functions, including intestinal functioning and gut microbiota balance. Dietary polyphenols can be a strategy for obesity management, collaborating to preserve or recover gut health through antioxidant and anti-inflammatory actions, as well as modulators of the microbiota. This study describes a systematic review protocol to elucidate effects of polyphenols on intestinal health of pre-clinical models with diet-induced obesity. AIM: Our aim is to evaluate evidence about polyphenols' effects in the gut microbiota composition and diversity, parameters of the physical and molecular status of the gut barrier in obese models, additionally, understand the possible involved mechanisms. METHODOLOGY: A protocol was developed and published on PROSPERO (Registration No: CRD42021262445). Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols is used to outline the protocol. The articles will be selected according to the PICOS strategy (population, interventions, control, outcome, and study design) in the following databases: PubMed, Science Direct, Scopus, Web of Science, and EMBASE. Experimental studies performed on rats and mice with a control group that describes treatment with polyphenols (from food matrix or crude extracts or isolated compounds) at any frequency, time, and dose will be included. Two reviewers will, independently, select the papers, extract data, and evaluate the data quality. The Systematic Review Center for Laboratory Animal Experimentation (SYRCLE) tool will be used to assess the risk of bias. EXPECTED RESULTS: Results will be showed through of native synthesis and, if possible, a metanalysis will be conducted. The review produced with this protocol can show the scientific evidence level about polyphenols' effects in intestinal health in obesity status.

What are the digestion and absorption models used to reproduce gastrointestinal protein processes?: A protocol for systematic review.

BACKGROUND: Animal, cell, and in vitro studies have been applied to simulate the human gastrointestinal tract (GIT) and evaluate the behavior of biomolecules. Understanding the peptides and/or proteins stability when exposed to these physiological conditions of the GIT can assist in the application of these molecules in the treatment of diseases such as obesity. This study describes a protocol of systematic reviews to analyze the methodologies that mimic the digestive and absorptive processes of peptides and/or proteins. METHODS: The protocol follows the guidelines described by Preferred Reporting Items for Systematic Reviews and Meta-Analyzes Protocols (PRISMA-P). The search strategies will be applied in the electronic databases PubMed, ScienceDirect, Scopus, Web of Science, Evidence portal, Virtual Health Library, and EMBASE. The intervention group will be formed by in vivo, in cells, and in vitro (gastrointestinal simulating fluids) studies of digestion and absorption of peptides and/or proteins presenting a schedule, duration, frequency, dosages administered, concentration, and temperature, and the control group consisting in studies without peptides and/or proteins. The selection of studies, data extraction, and assessment of the risk of bias will be carried out independently by 2 reviewers. For animal studies, the risk of bias will be assessed by the instrument of the Systematic Review Center for Experimentation with Laboratory Animals (SYRCLE) and the Office of Health Assessment and Translation (OHAT) tool will be used to assess the risk of bias in cell studies. RESULTS: This protocol contemplates the development of 2 systematic reviews and will assist the scientific community in identifying methods related to the digestive and absorptive processes of peptides and/or proteins. CONCLUSION: Both systematic reviews resulting from this protocol will provide subsidies for the construction of research related to the clinical application of bioactive peptides and/or proteins. In this context, they will make it possible to understand the gastrointestinal processes during administering these molecules, as the gastrointestinal environment can affect its functionality. Therefore, validating the effectiveness of these protocols is important, as it mimics in vitro biological conditions, reducing the use of animals, being consistent with the reduction, refine and replace program.

Training in communication skills for self-efficacy of health professionals: a systematic review.

BACKGROUND: Communication skills are essential for health professionals to establish a positive relationship with their patients, improving their health and quality of life. In this perspective, communication skills training can be effective strategies to improve the care provided by professionals in patient care and the quality of health services. OBJECTIVE: To identify the best available evidence on training programs in communication skills to promote changes in attitude and behavior or self-efficacy of health professionals. METHODS: Systematic searches were performed in eight databases, evaluating Randomized Controlled Trials and quasi-experimental studies with a control group, focusing on training communication skills for health professionals, who assessed self-efficacy or behaviors related to these skills. The phases of study selection and data extraction were carried out by two independent researchers, and the conflicts were resolved by a third. The risk of bias was assessed using the Cochrane method. RESULTS: Eight studies were included in the review. Most programs lasted between 4½ h and 2 days, involved information about communication skills and the content was applied to the health professionals' context. Several teaching strategies were used, such as lectures, videos and dramatizations and the evaluation was carried out using different instruments. Improvements in the performance and in the self-efficacy of communication skills were observed in the trained groups. The RCT had a low risk of bias and the quasi-experimental studies had a moderate risk. CONCLUSION: Training in communication skills can improve the performance and self-efficacy of health professionals. Programs that approach the conceptual issues and promote the space for experiential learning could be effective in communication skills training for professionals. PROSPERO: CRD42019129384.

Media and scientific communication about the COVID-19 pandemic and the repercussions on the population's mental health: A protocol for a systematic review and meta-analysis.

BACKGROUND: Good communication strategies are essential in times of crisis, such as the coronavirus pandemic. The dissemination of inaccurate information and the need for social isolation to control coronavirus disease 2019 (COVID-19) have shown a negative impact on the population, causing damage to mental health, with the appearance or worsening of symptoms of stress, fear, anxiety, and depression. Thus, the systematic review study is intended to gather evidence on the impact of information about COVID-19 on the mental health of the population. METHODS: This systematic review protocol is conducted using the guidelines of the preferred reporting items for systematic reviews and meta-analyses protocols and the Cochrane Handbook for Systematic Reviews of Interventions. The review aims to include published studies that address the exposure of the general population to information about COVID-19, through observational and experimental studies, which consider the following outcomes: fear, stress, anxiety, and depression. Thus, a comprehensive research strategy will be conducted in the following databases: PubMed / Medline, Scopus, Web of Science, EMBASE, Science Direct, CINAHL, PsycINFO and Cochrane Central Register of Controlled Trials (CENTRAL). Two independent reviewers will perform all procedures, such as study selection, data collection, and methodological evaluation. Disagreements will be forwarded to a third reviewer. RevMan 5.3 software will be used for data analysis. RESULTS: This systematic review will provide evidence of the influence of access to and consumption of media and scientific information about COVID-19 on the mental health of the population. It will consider information about the characterization of the study and the population studied, clinical and epidemiological information on mental health, and data on access to and consumption of media and scientific information. DISCUSSION: The results should inform about the consequences of communication about the new coronavirus on the emergence or worsening of psychological and psychiatric symptoms, allowing to develop strategies to achieve effective communication of information to promote the mental health of the population.

The Effects of Exercise on BDNF Levels in Adolescents: A Systematic Review with Meta-Analysis.

The aim of this study was to analyze the evidence available in the literature about the effects of exercise on brain-derived neurotrophic factor levels in adolescents. The literature searches were conducted in PubMed, Embase, Scopus, ScienceDirect, Web of Science, SportDiscus, the Cochrane Central Register of Controlled Trials (CENTRAL) and CINAHL. Randomized controlled trials and non-randomized controlled trials performed with adolescents (10-19 years) who underwent different exercise programs and who evaluated BDNF levels before and after the intervention were included. We included six studies, four RCTs and two non-RCTs in the systematic review with a total of 407 adolescents. In two randomized trials and one non-RCT, the intervention groups showed significant improvements in BDNF levels compared with the control group. The results presented in the meta-analysis indicate that despite the positive effect in favor of the intervention, there were no significant differences (standardized mean difference 0.28 ng/mL, 95% confidence interval -0.28 to 0.85; p = 0.32, I² = 0%). The results presented in our review indicate that aerobic exercise programs practiced in moderate- or high-intensity are promising strategies to increase BDNF levels in adolescents. However, further studies are required to support this finding.

The Control and Prevention of COVID-19 Transmission in Children: A Protocol for Systematic Review and Meta-analysis.

BACKGROUND: The pandemic following the rapid spread of the new SARS-CoV-2 virus has hit all continents and caused thousands of deaths worldwide. Evidence has been published on epidemiological and clinical characteristics of population groups considered at risk; however, information for the other population groups, especially for the child population, is needed. In this context, this protocol describes a systematic review that will aim to identify the evidence on control and prevention of COVID-19 transmission among children and adolescents, as well as to describe the epidemiological profile and clinical and immunological characteristics of COVID-19 in this population. METHODS: This protocol will be developed in accordance with PRISMA-P. The searches will be conducted in PubMed, Web of Science, ScienceDirect, EMBASE, and Scopus, seeking clinical trials. Observational studies and case reports with Children and adolescents (≤19 years) infected with SARS-CoV-2 will be included whether they report information on the control of prevention and COVID-19 transmission. Two independent researchers will perform the selection of articles, removal of duplication, and screening by Rayyan QCRI application. Cochrane's RoB 2.0, ROBINS-I, and CASP tools will be used to assess the risk of bias. Meta-analysis, subgroup analyses, and/or descriptive analyses will be carried out based on the data conditions included. RESULTS: A high-quality synthesis of the available evidences on the epidemiological profile, the clinical and immunological characteristics involved in children, and adolescents diagnosed with COVID-19, as well as the participation of this population in the transmission dynamics of SARS-CoV-2 will be provided. CONCLUSION: This systematic review has an important relevance in the current context because it has a great potential to help the development of new control and prevention strategies in the pediatric population.

Escolhas para uma vida saudável: intervenção nutricional em adolescentes escolares / Choices for a healthy life: nutritional intervention in school adolescents

O aumento na prevalência da obesidade precoce, sobretudo nas primeiras décadas do século XXI, se converteu em importante problema de saúde pública com proporções mundiais, especialmente, em função de que a obesidade entre as crianças e adolescentes tende a persistir na idade adulta e estar fortemente associada ao desenvolvimento de doenças crônicas e aumento no risco de óbito. Ações tornam-se relevantes e necessárias para conter essa progressão e, nesse sentido, o ambiente escolar mostra-se adequado para intervenções educacionais para a prevenção e combate a obesidade. O Programa AME "Atitude, Movimento e Escolhas para uma vida saudável" foi elaborado no Programa de Pós Graduação em Saúde Coletiva da Universidade Federal do Rio Grande do Norte e trata-se de uma intervenção multicomponente, baseada na escola, com a abordagem na educação em saúde voltada para alimentação adequada e saudável e estímulo ao estilo de vida ativo (redução do comportamento sedentário e prática de atividade física). O objetivo da tese de doutorado é desenvolver estratégias de Educação Alimentar e Nutricional (EAN) em um programa de intervenção multicomponente baseada na escola para promoção de alimentação adequada e saudável e estilo de vida ativo entre adolescentes. Trata-se de uma pesquisa de desenvolvimento em que foi utilizada a literatura científica atual e disponível com o intuito de elaborar estratégias do eixo de EAN do Programa AME. O método está organizado em duas seções, a primeira descreveu o método dos estudos de revisões sistemáticas (RS) que contribuíram com o embasamento técnico-científico para o desenvolvimento do protocolo; e a segunda seção descreveu o protocolo do ensaio clínico randomizado (ECR). Na primeira seção, duas RS foram desenvolvidas seguindo as recomendações dos Itens para Relatório Preferenciais para Revisões Sistemáticas e Meta-análises (PRISMA) e foram registradas no International prospective register of systematic reviews (PROSPERO - CRD42019116520 e CRD42019100914). Para contextualizar onde está inserido o eixo EAN do Programa AME, a segunda seção apresenta os métodos do ECR. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa (CEP-HUOL UFRN) e registrada no Registro Brasileiro de Ensaios Clínicos (RBR-86xv46). A tese de doutorado está organizada no formato coletânea de artigos. A primeira RS investiga a efetividade de intervenções de EAN baseado na escola e seus efeitos sobre o consumo alimentar de adolescentes e nela foram incluídos 24 ECR. Em 16 estudos a intervenção conseguiu melhorar o consumo de pelo menos um alimento ou grupo de alimentos recomendados como alimentos saudáveis. Os resultados indicam que as intervenções baseadas na escola estão gerando mudanças favoráveis no consumo alimentar de adolescentes. A segunda RS investiga as evidências científicas quanto à associação entre o consumo de carne vermelha e doenças cardiovasculares, incluindo o efeito dose-resposta e nela foram incluídos 22 estudos prospectivos de coorte. Os resultados indicam uma possível associação entre o consumo de carne vermelha, especialmente carne processada, e a incidência e mortalidade por doença cardíaca coronária, derrame e/ou insuficiência cardíaca. A tendência de dose resposta linear indica que, quanto maior o consumo de carne vermelha, maior o risco de incidência e mortalidade por doenças cardiovasculares. Assim, baseada nos resultados encontrados nas RS, no contexto do ECR e aliadas às recomendações de documentos oficiais da Organização Mundial da Saúde, Ministério da Saúde do Brasil e instituições internacionais, foi realizada a construção da fundamentação teórica da proposta de intervenção do eixo de EAN do Programa AME. O estudo apresenta a justificativa para o desenvolvimento do eixo; as teorias orientadoras do programa AME; objetivos e metas; e características do eixo EAN do programa AME. Desenvolver estratégias de EAN em um programa de intervenção multicomponente baseada na escola para promoção de estilo de vida ativo e alimentação adequada e saudável entre adolescentes poderá propiciar aos adolescentes a construção de pensamentos críticos e reflexivos, que poderão transformar sua vida, a de sua família, comunidade e até mesmo de seu território (AU).

The increase in the prevalence of early obesity, especially in the first decades of the 21st century, has become an important public health problem of worldwide proportions. This is due to the fact that obesity among children and adolescents tends to persist in adulthood and is strongly associated with the development of chronic diseases and increased risk of death. Actions become relevant and necessary to contain this progression, in this sense, the school environment is suitable for educational interventions to prevent and combat obesity. The AME Program "Attitude, Movement and Choices for a Healthy Life" was developed in the Postgraduate Program in the Collective Health at the Federal University of Rio Grande do Norte and is a multicomponent, including school-based food and nutrition education, reduction of sedentary behavior, and the practice of physical activity. The objective of the doctoral thesis is to develop strategies in Food and Nutrition Education (FNE) in a schoolbased multicomponent intervention program to promote adequate and healthy food and active lifestyle among adolescents. This is a developmental research in which the current scientific literature was used and available in order to develop strategies for FNE axis of the AME Program. The method is organized in two sections, the first described the method of studies of systematic reviews (SR) that contributed with the technical-scientific basis for the development of the protocol; and the second section described the protocol of the randomized clinical trial (RCT). In the first section, two SRs were developed following the recommendations of the Preferred Report Items for Systematic Reviews and Meta-analyzes (PRISMA) and were registered in the International prospective register of systematic reviews (PROSPERO - CRD42019116520 and CRD42019100914). To contextualize where the FNE axis of the AME Program is inserted, the second section presents the methods of the RCT. The research was approved by the Research Ethics Committee (CEP-HUOL UFRN) and registered in the Brazilian Registry of Clinical Trials (RBR-86xv46). The doctoral thesis is organized in the collection of articles. The first SR investigates the effectiveness of schoolbased FNE interventions and their effects on adolescent food consumption and 24 RCTs were included. In 16 studies, the intervention managed to improve the consumption of at least one food or group of foods recommended as healthy foods. The results indicate that school-based interventions are generating favorable changes in adolescent food consumption. The second SR investigates the scientific evidence regarding the association between red meat consumption and cardiovascular diseases, including the dose-response effect and 22 prospective cohort studies were included. The results indicate a possible association between the consumption of red meat, especially processed meat, and the incidence and mortality from coronary heart disease, stroke and / or heart failure. The trend of linear dose response indicates that the greater the consumption of red meat, the greater the risk of incidence and mortality from cardiovascular diseases. Thus, based on the results found in the SR, in the context of the RCT and combined with the recommendations of official documents of the World Health Organization, Ministry of Health of Brazil and international institutions, the theoretical foundation of the intervention proposal for the FNE axis of the AME Program was carried out. The study presents the rationale for the development of the axis; the guiding theories of the AME program; goals and objectives; and characteristics of the FNE axis of the AME program. Developing FNE strategies in a school-based multicomponent intervention program to promote an active lifestyle and adequate and healthy nutrition among adolescents may provide adolescents with the construction of critical and reflective thoughts that can transform their lives, that of their families, community and even their territory (AU).

Mechanism of the action of bioactive proteins of vegetables in diabetes mellitus type 2: Systematic review protocol.

BACKGROUND: Diabetes mellitus type 2 (DM2) is a chronic disease of significant prevalence causing hyperglycemia and several comorbidities. Evidences highlight the performance of non - protein bioactive compounds found in vegetables in the control of hyperglycemia. This study describes a protocol of a systematic review, which analyzes the action of proteins and bioactive peptides of plants in DM2. METHODS: The Preferred Reporting Items guide this protocol for Systematic Reviews and Meta-Analyzes Protocols (PRISMA-P) was used. The databases that will be used for searching will be PubMed, ScienceDirect, Scopus, Web of Science, EMBASE, and Virtual Health Library, Brazil (VHL). Studies that use bioactive proteins and peptides of vegetal origin in DM2 will be included in the systematic review. The studies will be identified using clinical parameters and the effect on insulin resistance. The characteristics of the studies as control groups, test substance, dosage, intervention time, and the main results will be described. Selection of studies, data extraction, and methodological quality assessment will be performed independently by two experienced reviewers. RESULTS: This protocol will be the basis for a systematic review identifying the mechanism of action of plant proteins and peptides in type 2 diabetes mellitus. CONCLUSION: Systematic reviews from this protocol will provide support for the construction of researches that analyze the effect of plant bioactive proteins and peptides on the control of hyperglycemia and how these molecules act in the control of DM2.

Red meat consumption, risk of incidence of cardiovascular disease and cardiovascular mortality, and the dose-response effect: Protocol for a systematic review and meta-analysis of longitudinal cohort studies.

BACKGROUND: Red and (particularly) processed meats are high in cholesterol and saturated and solid fatty acids. Their consumption is considered one of the risk factors for metabolic disorders. Numerous studies demonstrated a possible association between red meat consumption and cardiovascular disease (CVD). In this protocol, we propose a systematic review of the literature to examine the associations of red meat consumption with CVD incidence and mortality, and explore the potential dose-response relationship. METHODS: We will search MEDLINE/PubMed, Scopus, SciELO, LILACS, ScienceDirect, Web of Science, Cochrane (CENTRAL), WHOLIS, PAHO, and Embase. We will include prospective epidemiological studies (longitudinal cohort). Risk of bias will be assessed using the Newcastle-Ottawa scale (NOS). Four independent researchers will conduct all evaluations. Disagreements will be referred to a fifth reviewer. We will summarize our findings using a narrative approach and tables to describe the characteristics of the included studies. The heterogeneity between trial results will be evaluated using a standard chi-squared test with P < .05. We will conduct the study in accordance with the guideline of the Preferred Reporting Items for Systematic Review and Meta-analyses Protocols (PRISMA-P). RESULTS: This review will evaluate the association between red meat consumption and incidence of CVD and mortality (primary outcome measures). The secondary outcome measure will include the dose-response effect. CONCLUSION: The findings of this systematic review will summarize the latest evidence of the association between red meat consumption and incidence of CVD and mortality and the dose-response effect through a systematic review and meta-analysis.

Influence of curcumin supplementation on metabolic and lipid parameters of people living with HIV/AIDS: a randomized controlled trial.

BACKGROUND: Scientific studies have shown that the potential therapeutic efficacy of curcumin in several diseases is due to its potent antioxidant and anti-inflammatory properties. Consequently, curcumin supplementation seems to be a valuable alternative for HIV-infected individuals. The aim of this study is to evaluate the influence of curcumin supplementation on substrate oxidation at rest, body composition, and the lipid profile of physically active people living with HIV/AIDS under antiretroviral therapy. METHODS: This double-blind, crossover, randomized clinical trial was comprised of 20 subjects divided into experimental (EG) and control (CG) groups, receiving 1000 mg curcumin/day and placebo, respectively, during a 30-day period. Substrate oxidation at rest was assessed by indirect calorimetry, body composition was measured by dual-energy x-ray absorptiometry, and the lipid profile was evaluated by blood tests. Data analysis was performed by independent samples and paired t-tests to compare the differences between groups and times. A p-value < 0.05 was accepted as significant. RESULTS: There were no differences between groups regarding substrate oxidation at rest or body composition. However, serum triglyceride levels were increased after curcumin supplementation (182 vs. 219 mg/dL; p = 0.004). CONCLUSION: Curcumin supplementation promoted the elevation of serum triglyceride levels in HIV-infected subjects. Further studies with a larger sample cohort, different curcumin doses, and longer intervention times are needed to validate current observations. In addition, the influence of physical activity, dietary intake, and genetic polymorphisms must be considered in future studies to better understand the impact of curcumin supplementation on the lipid profile of people living with HIV/AIDS under antiretroviral therapy.

Training programs in communication skills to improve self-efficacy for health personnel: Protocol for a systematic review and meta-analysis.

BACKGROUND: Patient-centered care should be the focus of health services, where improvements in the communication skills of health professionals promote excellent health and quality care. Thus, this study is a protocol for a systematic review and meta-analysis to evaluate the effectiveness of training programs in communication skills to promote self-efficacy in the communication of health personnel. METHODS: This systematic review protocol is conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) statement guidelines and the Cochrane Handbook of Systematic Reviews of Interventions. The review should include studies carried out with health professionals who have undergone training in communication skills aimed at promoting their self-efficacy. Clinical trials (randomized, non-randomized), community trials, and quasi-experimental studies should be included. Therefore, the comprehensive search strategy will be conducted in the following databases: PubMed/Medline, Scopus, Web of Science, EMBASE, Science Direct, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials (CENTRAL). Two independent reviewers will conduct all study selection procedures, data extraction, and methodological evaluation, and disagreements will be referred to a third reviewer. RevMan 5.3 software will be used to gather data and perform the meta-analysis if possible. RESULTS: This systematic review will provide evidence on more effective programs for communication skills training and will consider information such as duration, educational strategies, assessment measures, and outcomes that promote health worker self-efficacy. DISCUSSION: This systematic review should provide evidence for effective communication skills training for health professionals in order to guide new strategies for quality care. DISSEMINATION AND ETHICS: The findings of this scoping review will be disseminated in print, at conferences, or via peer-reviewed journals. Ethical approval is not necessary as this paper does not involve patient data. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019129384.
