Oferta de prep em organizações comunitárias: estudo comparativo com serviços convencionais / Prep provision in community organizations: a comparative study with conventional services

RESUMO OBJETIVO: Avaliar se adolescentes de minorias sexuais que iniciaram a profilaxia pré-exposição sexual (PrEP) em organizações comunitárias (OC) apresentam maior vulnerabilidade social e ao HIV em comparação com adolescentes em PrEP de um serviço de saúde convencional. Além disso, avaliar se esses adolescentes tiveram um acesso mais oportuno à profilaxia. MÉTODOS: Estudo demonstrativo da efetividade de PrEP, realizado na cidade de São Paulo, em duas OC, localizadas no centro (OC-centro) e na periferia (OC-periferia), e em um serviço convencional de testagem para o HIV (CTA-centro). Foram elegíveis para PrEP, entre 2020 e 2022, adolescentes homens cisgêneros que fazem sexo com homens (aHSH), travestis, mulheres transexuais e pessoas transfemininas (aTTrans), de 15 a 19 anos, HIV-negativos e com práticas de maior risco para o HIV. Indicadores de acesso oportuno e de vulnerabilidades dos adolescentes iniciando PrEP nas OC foram analisados, tendo por referência o CTA-centro e empregando regressão logística multinomial. RESULTADOS: 608 adolescentes iniciaram PrEP nas OC e CTA-Centro. Adolescentes das OC estiveram associados a um menor tempo de início de PrEP (1-7 dias; OC-periferia: ORa = 2,91; IC95% 1,22-6,92; OC-centro: ORa = 1,91; IC95% 1,10-3,31); e a um menor IDH de moradia (OC-centro: ORa = 0,97; IC95% 0,94-1,00; OC-periferia: ORa = 0,82; IC95% 0,78-0,86). Na OC-periferia houve aumento na chance de os adolescentes serem mais jovens (ORa = 3,06; IC95% 1,63-5,75) e morarem mais próximos ao serviço (ORa = 0,82; IC95% 0,78-0,86, média 7,8 km). Enquanto adolescentes da OC-centro estiveram associados ao maior conhecimento prévio de PrEP (ORa = 2,01; IC95% 1,10-3,91) e a alta percepção de risco (ORa = 2,02; IC95% 1,18-3,44). Não estiveram associadas aos adolescentes das OC as práticas sexuais de maior risco e as situações de vulnerabilidade ao HIV. CONCLUSÕES: A oferta de PrEP nas OC facilitou o acesso de adolescentes vulnerabilizados e pode contribuir para reduzir inequidades.

ABSTRACT OBJECTIVE: To evaluate whether adolescents from sexual minorities who initiated pre-exposure prophylaxis (PrEP) in community-based organizations (COs) are more socially and HIV-vulnerable compared with their counterparts from a conventional health service. In addition, to evaluate whether these adolescents had more timely access to prophylaxis METHODS: A PrEP demonstration study was conducted in the city of São Paulo in two COs, located in the center (CO-center) and the outskirts (CO-outskirts), and a conventional HIV testing service (CTA-center). Between 2020 and 2022, cisgender male adolescents who have sex with men (aMSM), transgender and gender diverse adolescents (aTTrans) aged 15 to 19 years, HIV-negative, with higher-risk practices for HIV were eligible for PrEP. Indicators of timely access and vulnerabilities of adolescents initiating PrEP in COs were analyzed using CTA-center as a reference and multinomial logistic regression. RESULTS: 608 adolescents initiated PrEP in COs and CTA-center. Adolescents from COs were associated with a shorter time to PrEP initiation (1-7 days; CO-outskirts: ORa = 2.91; 95%CI 1.22-6.92; CO-center: ORa = 1.91; 95%CI 1.10-3.31); and a lower housing Human Development Index (HDI) (CO-center: ORa = 0.97; 95%CI 0.94-1.00; CO-outskirts: ORa = 0.82; 95%CI 0.78-0.86). In CO-outskirts, there was an increased chance of adolescents being younger (ORa = 3.06; 95%CI 1.63-5.75) and living closer to the service (ORa = 0.82; 95%CI 0.78-0.86, mean 7.8 km). While adolescents from the CO-center were associated with greater prior knowledge of PrEP (ORa = 2.01; 95%CI 1.10-3.91) and high-risk perception (ORa = 2.02; 95%CI 1.18-3.44), adolescents from the COs were not associated with higher-risk sexual practices and situations of vulnerability to HIV. CONCLUSION: The provision of PrEP in the COs facilitated access for vulnerable adolescents and may contribute to reducing inequities.

Influencia de la musicoterapia en el paciente durante la atención estomatológica

Ser atendido por el estomatólogo es una de las situaciones que genera más miedo y ansiedad en las personas. Se sugiere que la musicoterapia contribuye a reducir estos síntomas. Teniendo en cuenta que muchos pacientes presentan ansiedad y miedo al ser atendidos en el sillón dental y que necesitan un ambiente más agradable, constituye el motivo que condujo a la realización de este trabajo haciendo uso de la musicoterapia con el objetivo de evaluar su influencia en el paciente durante la atención. Se realizó un estudio de intervención, desde marzo a junio del 2022 en el Servicio Estomatológico, Policlínico Tula Aguilera. La muestra, 40 pacientes, fue seleccionada al azar, independientemente de sentir temor o no al tratamiento estomatológico. Las sesiones se dividieron: primera visita (sin música) y segunda visita (con música). Los datos se recogieron en encuesta. Los niveles de miedo disminuyeron con la aplicación de la terapia, por lo cual se constató que la musicoterapia tiene una notable influencia en los pacientes al desaparecer y disminuir el miedo o sensaciones desagradables durante la atención estomatológica. Todos los pacientes manifestaron satisfacción con el uso de la música, durante el servicio.

To be assisted by the odontologist is one of the situations that generates more fear and anxiety in people. It is suggested that the musical-therapy contributes to reduce these symptoms. Keeping in mind that many patients present anxiety and fear when being assisted in the dental armchair and that they need a more pleasant atmosphere, it constitutes the reason that led to the realization of this work making use of the musical-therapy with the objective of evaluating their influence in the patient during the attention. He was carried out an intervention study, from March to June of the 2022 in the Dentistry Service, Clinical Tula Aguilera. The sample, 40 patients, it was selected at random, independently of feeling fear or not to the dentistry treatment. The sessions were divided: first visit (without music) and second visit (with music). The data were picked up in survey. The levels of fear diminished with the application of the therapy, reason why it was verified that the musical-therapy has a notable it influences in the patients when disappearing and to diminish the fear or unpleasant sensations during the dentristry attention. All the patients manifested satisfaction with the music's use, during the service.

Effectiveness of a multicomponent intervention to face the COVID-19 pandemic in Rio de Janeiro's favelas: difference-in-differences analysis.

INTRODUCTION: Few community-based interventions addressing the transmission control and clinical management of COVID-19 cases have been reported, especially in poor urban communities from low-income and middle-income countries. Here, we analyse the impact of a multicomponent intervention that combines community engagement, mobile surveillance, massive testing and telehealth on COVID-19 cases detection and mortality rates in a large vulnerable community (Complexo da Maré) in Rio de Janeiro, Brazil. METHODS: We performed a difference-in-differences (DID) analysis to estimate the impact of the multicomponent intervention in Maré, before (March-August 2020) and after the intervention (September 2020 to April 2021), compared with equivalent local vulnerable communities. We applied a negative binomial regression model to estimate the intervention effect in weekly cases and mortality rates in Maré. RESULTS: Before the intervention, Maré presented lower rates of reported COVID-19 cases compared with the control group (1373 vs 1579 cases/100 000 population), comparable mortality rates (309 vs 287 deaths/100 000 population) and higher case fatality rates (13.7% vs 12.2%). After the intervention, Maré displayed a 154% (95% CI 138.6% to 170.4%) relative increase in reported case rates. Relative changes in reported death rates were -60% (95% CI -69.0% to -47.9%) in Maré and -28% (95% CI -42.0% to -9.8%) in the control group. The case fatality rate was reduced by 77% (95% CI -93.1% to -21.1%) in Maré and 52% (95% CI -81.8% to -29.4%) in the control group. The DID showed a reduction of 46% (95% CI 17% to 65%) of weekly reported deaths and an increased 23% (95% CI 5% to 44%) of reported cases in Maré after intervention onset. CONCLUSION: An integrated intervention combining communication, surveillance and telehealth, with a strong community engagement component, could reduce COVID-19 mortality and increase case detection in a large vulnerable community in Rio de Janeiro. These findings show that investment in community-based interventions may reduce mortality and improve pandemic control in poor communities from low-income and middle-income countries.

Blood Pressure Changes After a Health Promotion Program Among Mexican Workers.

Background: Cardiovascular disease is becoming increasingly prevalent in low and middle-income countries (LMIC), and high blood pressure (BP) is one of the main risk factors. The efficacy and sustainability of worksite health promotion (WHP) programs for BP reduction in LMIC have yet to be determined. Methods: This non-randomized company-based trial evaluated 6- and 12-months effects of a WHP intervention on BP among 2,002 participating workers from seven Mexican companies. Intervention and control groups were assigned at the company level. The intervention included nutrition counseling, physical exercise, and stress management components. Mixed models assessed differences in BP change between intervention and control companies in intent-to-treat (ITT), per-protocol (PerP), and as-treated (AsTr) analyses, and also within-group changes stratified by company, intervention component, and baseline cardiovascular risk factor levels. All analyses were adjusted for potential confounders. We accounted for missing data and loss to follow-up using inverse probability of censoring weighting. Results: ITT analyses revealed mean BP change differences of -1.1 mmHg at 12 months (95% CI: -2.9; 0.6) in intervention companies relative to control companies. PerP and AsTr analyses confirmed this finding. Within-group analyses showed consistent BP reductions at both 6 and 12 months. Substantial differences in BP changes ranging from diastolic -6.1 mmHg, (95% CI: -11.2; -1.2) to systolic -13.0 mmHg (95% CI: -16.0; -10.1) were found among individuals with diabetes at baseline in intervention companies relative to control companies. Conclusion: After 1 year, WHP was associated with modest but uncertain BP reductions. Substantial reductions were mainly observed among diabetic workers.

Challenges and opportunities in the science of research to practice: lessons learned from a randomized controlled trial of a sexual risk-reduction intervention for psychiatric patients in a public mental health system

Objective: Human immunodeficiency virus (HIV) prevention efficacy trials with psychiatric patients have been conducted in research settings in high-resourced countries, establishing short-term efficacy for reducing sexual risk behavior. None has been implemented within systems of care. In the last decade, overcoming this research-to-practice gap has become a focus of implementation science. This paper describes the first and only HIV Prevention intervention trial for psychiatric patients conducted in real-world outpatient psychiatric settings facilitated by trained clinic-based providers. Methods: The HIV Prevention intervention, which uses the Information-Motivation-Behavioral Skills model to achieve sexual risk-reduction, was rigorously adapted to the local context and clinic services' needs. Participants from eight clinics were randomized to HIV Prevention or Health Promotion conditions. Results: HIV Prevention participants showed significant improvement in Information-Motivation-Behavioral domains; in this group, behavioral intentions were associated with significantly fewer unprotected sex occasions, but reduction of unprotected sex occasions was similar in both conditions. Conclusion: Our trial was conducted before implementation studies became widely funded. Transporting an intervention to a new culture or into real-world practice settings may require adaptations. Our results demonstrate that clear guidelines are needed regarding whether to conduct efficacy, effectiveness, and/or implementation research as the most appropriate next step.

Açaí (Euterpe oleracea Mart.) and juçara (Euterpe edulis Mart.) juices improved HDL-c levels and antioxidant defense of healthy adults in a 4-week randomized cross-over study.

OBJECTIVE: To evaluate the effects of moderate-term açaí and juçara juice intake on fasting glucose, lipid profile, and oxidative stress biomarkers in healthy subjects. METHODS: A randomized cross-over study was performed with 30 healthy adults. The subjects were assigned to drink 200 mL/day of açaí or juçara juice for four weeks with a 4-week washout period. Before and after each nutritional intervention, blood samples were obtained to evaluate the outcomes: fasting glucose, total cholesterol, triglycerides, high-density lipoprotein-cholesterol (HDL-c), low-density lipoprotein-cholesterol (LDL-c), small, dense LDL-c (sd-LDL-c), total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), uric acid, and activity of the enzymes superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). RESULTS: After four weeks, açaí and juçara juices increased the concentrations of HDL-c by 7.7% and 11.4%, respectively (P < 0.05). In addition, açaí juice intake promoted significant increases in TAC (66.7%), CAT (275.1%), GPx (15.3%), and a decrease in OSI (55.7%) compared to baseline (P < 0.05 for all). Juçara juice intake significantly increased CAT activity (~15.0%) in relation to baseline. No significant intergroup differences were observed for any outcomes (P > 0.05). CONCLUSION: The results indicated a positive impact of regular consumption of açaí and juçara juices on the HDL-c levels, as well as on the antioxidant enzyme activities, which may contribute to cardiovascular health.

Impact of multidimensional interventions on quality of life and depression among older adults in a primary care setting in Brazil: a quasi-experimental study

Objective: To evaluate the impact of multidimensional interventions on quality of life (QoL) and depressive symptoms in Brazilian older adults living in the community. Methods: Longitudinal, quasi-experimental study of older adults receiving conventional primary health care (PHC). The interventions were designed in response to a first round of data collection and validated through pilot testing in groups of older adults from another community. The validated interventions were then applied to an intervention group (IG). To measure their effect, we used the Medical Outcomes Short-Form Health Survey (SF-36) quality of life scale and the Geriatric Depression Scale (GDS-30). Results: The sample comprised 118 participants. IG participants exhibited significant improvement in several QoL domains (SF-36): mental health (p = 0.010), general health perceptions (p = 0.016), and physical functioning (p = 0.045). No such improvement occurred in controls (p > 0.050). The prevalence of depression (GDS-30) fell from 36.7 to 23.3% in the IG, despite no significant difference (p = 0.272). Controls also reported a reduction in depressive symptoms, but only from 44.8 to 41.4% (p = 0.112). Conclusions: This multidimensional intervention was associated with significant improvement in mental health, general health perceptions, and physical functioning in a sample of Brazilian older adults. Clinical trial registration: RBR-92dbtx.

ABSTRACT Objective Evaluate the effectiveness of mHealth strategy on sodium consumption markers. Methods Intervention study carried out with 175 adults (20-59 years), from an educational institution of Vitória, Espírito Santo State. Participants were made aware through posters, oral approach and electronic media. Anthropometric, hemodynamic, socioeconomic, health, and dietary practices data was collected in two stages. After the first assessment, participants were randomized into two groups: Intervention Group and Control Group. The Intervention Group included 21 electronic messages and 3 videos on healthy eating focusing on the goal to reduce sodium intake for 3 months. Behavioral changes were assessed using the Generalized Estimation Equation (p-value <0.05). Results At baseline, no significant differences in socioeconomic, anthropometric and health variables, and eating practices between groups were observed. The stock broth cube was the most used ready processed seasoning. After the intervention, a reduction in the use of stock broth was observed only in the intervention group (β=0.615; p=0.016). In addition, 73% of the intervention group participants reported that the messages were clear, 67% reported that they were useful, and 48% stated they followed the guidelines. Conclusion There was a reduction in the frequency of use of stock broth cubes, demonstrating the potential effect of the m-Health strategy on sodium consumption markers in individuals without a hypertension medical diagnosis.

Effect of photobiomodulation therapy on postoperative pain after endodontic treatment: a randomized, controlled, clinical study.

OBJECTIVE: The aim of this prospective, randomized, clinical study was to assess the effect of photobiomodulation therapy (PBM) with low-level laser irradiation (LLLI) on postoperative pain after endodontic treatment. MATERIALS AND METHODS: Sixty patients, diagnosed with irreversible pulpitis in lower molar teeth, participated in the study. All treatments were performed by a single operator. Participants were randomly divided into two groups: in the experimental group (EG), endodontic treatment was performed with a reciprocating system, immediately followed by PBM with LLLI; and only endodontic treatment was performed in the control group (CG). Postoperative pain was assessed by a second examiner, who was blinded, using two scales: verbal rating scale (VRS) and numerical rating scale (NRS). Assessment was carried out at 6, 12, and 24 h after treatment. Data were analyzed using chi-squared, Fisher's exact, Mann-Whitney tests, ordinal, and non-parametric regression analyses. RESULTS: For the prevalence of pain, the difference between the groups was significant for the evaluations performed after 6 h (p = 0.04) and 24 h (p = 0.02). The difference after 24 h remained significant after stratification by sex and extrusion of filling material. Increased pain intensity was associated with extrusion of root canal filling material to the periapical region in the two scales used. CONCLUSION: The effect of PBM therapy after endodontic treatment showed a significant decreasein prevalence of postoperative pain. CLINICAL RELEVANCE: The PBM reduces the prevalence of postoperative pain and may benefit patients who need endodontic treatment.

School-Based Intervention on Cardiorespiratory Fitness in Brazilian Students: A Nonrandomized Controlled Trial.

BACKGROUND: In response to the worldwide increasing prevalence of low cardiorespiratory fitness (CRF), several interventions have been developed. The aim of this study was to examine the effect of a school-based intervention on CRF in Brazilian students. METHODS: A nonrandomised controlled design tested 432 students (intervention group: n = 247) from 6th to 9th grade recruited from two public secondary schools in Florianopolis, in 2015. The intervention entitled "MEXA-SE" (move yourself), applied over 13 weeks, included four components: (1) increases in physical activity during Physical Education classes; (2) active recess; (3) educational sessions; and (4) educational materials. CRF (20-m shuttle run test) was the primary outcome. RESULTS: The effect size of the intervention on CRF was 0.15 (CI 95% = -0.04; 0.34). In the within-group comparisons, VO2max decreased significantly from baseline to follow-up in the control group but remained constant in the intervention group. After adjustment variables, differences between intervention and control group were not statistically significant (p > 0.05). CONCLUSION: The "MEXA-SE" intervention did not have an effect on adolescents' CRF. However, maintenance of VO2max in intervention group and a reduction within control group demonstrates that this intervention may be beneficial for long-term CRF and, possibly, the increased intervention time could result in a better effect.

Ácido fólico em excesso: efeitos sobre o metabolismo das vitaminas B2 e B6, o catabolismo do triptofano e a resposta imune / Folic acid excess: effects on vitamin B2 and B6 metabolism, tryptophan catabolism and immune response

Introdução: A suplementação com ácido fólico (AF) é recomendada em algumas condições para evitar a deficiência de folato, como para mulheres no período periconcepcional e durante a gestação. Atualmente, existe uma preocupação quanto ao consumo excessivo de AF pela população pelo uso de suplementos com altas doses dessa vitamina. As vitaminas B6 e B2 agem como cofatores no metabolismo de um carbono, e o uso de altas doses de AF pode influenciar o metabolismo de ambas vitaminas e, consequentemente, interferir em metabolismos importantes das quais elas participam, como a via das quinureninas, e no sistema imune. Objetivo: Avaliar os efeitos da intervenção diária com uma alta dose de AF (5 mg) por 90 dias sobre marcadores do estado das vitaminas do complexo B, e as consequências sobre os metabólitos da via das quinureninas e o sistema imune em adultos saudáveis. Material e Métodos: 64 indivíduos saudáveis foram submetidos à intervenção diária com 5 mg de AF por 90 dias. Coletas de sangue foram realizadas antes (baseline) e após 45 e 90 dias de intervenção. As concentrações séricas de folato e vitamina B12 foram avaliadas por métodos microbiológicos. As concentrações séricas das vitaminas B6 (piridoxal 5'-fosfato (PLP), piridoxal (PL) e ácido 4-piridóxico (PA)), B2 (riboflavina e flavina mononucleotídeo (FMN)), B1 (tiamina e tiamina monofosfato (TMP)) e B3 (ácido nicotínico, nicotinamida e N1-metilnicotinamida), bem como de triptofano, quinurenina e metabólitos, foram avaliadas por LC-MS/MS. A proteína C-reativa ultrassensível (PCRus) foi determinada por imunoturbidimetria, e as concentrações séricas de interleucina (IL)-6, IL-8, IL-10, interferon gama (IFN-γ) e fator de necrose tumoral alfa (TNF-α) foram avaliadas por ensaio multiplex. A expressão de RNAm de DHFR (dihidrofolato redutase), MTHFR (metilenotetrahidrofolato redutase), IL8, TNFA e IFNG em leucócitos mononucleares (PBMC) foram avaliadas por PCR em tempo real. O número de células T regulatórias (Treg) (CD3+, CD4+, CD25high, FoxP3+, CD127-) foi avaliado após incubação dos PBMC com PMA e ionomicina ou veículo por 18h, por imunofenotipagem. Resultados: Houve um grande aumento das concentrações de folato sérico após 45 e 90 dias de intervenção com AF. Não houve diferença nas concentrações de vitamina B12 antes e após a intervenção. As concentrações séricas de PLP foram semelhantes antes e após a intervenção, entretanto, um aumento de PL sérico foi observado após 45 e 90 dias, e de PA após 45 dias, quando comparado ao baseline. Riboflavina e FMN foram maiores após 45 e 90 dias em relação ao baseline. A tiamina sérica foi menor após 45 dias, e as concentrações de TMP foram maiores após 90 dias quando comparados aos períodos anteriores. Não houve diferença nas concentrações de vitamina B3 antes e após a intervenção. Dentre os metabólitos da via das quinureninas, apenas o ácido antranílico apresentou aumento após 45 e 90 dias, enquanto o ácido picolínico diminuiu após 90 dias. PCRus, IL-6, IL-8, IL-10, IFN-γ e TNF-α séricos foram semelhantes no baseline e após a intervenção. Um aumento da expressão de RNAm de DHFR e TNFA foi observado após, respectivamente, 90 dias e 45 e 90 dias de intervenção. Após 90 dias de intervenção com AF, foi observada diminuição do número de células Treg após estímulo com PMA e ionomicina. Conclusão: O uso diário de 5 mg de AF foi associado a alterações nas concentrações séricas de marcadores do estado de vitaminas do complexo B e da via das quinureninas, bem como a diminuição do número de células Treg

Introduction: Folic acid (FA) supplementation is recommended in some conditions to avoid folate deficiency, as women during periconceptional period and pregnancy. Currently, there is a concern about the excessive consumption of FA by population by using supplements with high doses of this vitamin. Vitamins B6 and B2 are cofactors of enzymes of one carbon metabolism and, consequently, may disturb key metabolism in which they participate, as kynurenine pathway, and the immune system. Aim: To assess the effects of a daily intervention with high dose of FA (5 mg) for 90 days on biomarkers of complex B vitamins status and its outcomes in kynurenine pathway metabolites and immune system in healthy adults. Material and Methods: 64 healthy individuals were submitted to a daily intervention with 5 mg of FA for 90 days. Blood samples were collected before (baseline) and after 45 and 90 days of intervention. Serum folate and vitamin B12 were assessed by microbiological assays. Serum vitamin B6 (pyridoxal 5'-phosphate (PLP), pyridoxal (PL) and 4-pyridoxic acid (PA)), vitamin B2 (riboflavin and flavin mononucleotide (FMN)), vitamin B1 (thiamin and thiamin monophosphate)) and vitamin B3 (nicotinic acid, nicotinamide and N1-methylnicotinamide), as well as tryptophan, kynurenine and metabolites, were assessed by LC-MS/MS. C-reactive protein (hs-CPR) was assessed by immunoturbidimetry, and serum interleukin (IL)-6, IL-8, IL-10, interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α) were assessed by multiplex assay. Mononuclear leukocytes mRNA expression of DHFR (dihydrofolate reductase), MTHFR (methylenetetrahydrofolate reductase), IL8, TNFA and IFNG were assessed by real time PCR. Regulatory T Cell (Treg) number (CD3+, CD4+, CD25high, FoxP3+, CD127-) was determined after mononuclear leukocytes incubation with PMA and ionomycin or vehicle for 18h, by immunophenotyping. Results: A great increase on serum folate was observed after 45 and 90 days of FA intervention. No differences in serum vitamin B12 were observed before and after intervention. Serum PLP was similar before and after intervention, however, an increase in serum PL was observed after 45 and 90 days, and in PA after 45 days, when compared to baseline. Riboflavin and FMN were increased after 45 and 90 days than in baseline. Serum thiamine was decreased after 45 days than in baseline. Serum TMP was increased after 90 days when compared with previous timepoints. No differences in vitamin B3 were observed after and before FA intervention. Among kynurenine pathway metabolites, anthranilic acid was increased after 45 and 90 days, while picolinic acid was decreased after 90 days. hs-CPR, serum IL-6, IL-8, IL-10, IFN-γ and TNF-α were similar at baseline and after intervention. An increase on mRNA expression of DHFR and TNFA was observed after, respectively, 90 days and 45 and 90 days of intervention. After 90 days of FA intervention, it was observed a decrease on Treg cell number after PMA and ionomycin stimulation. Conclusion: Daily use of 5 mg of FA was associated with changes in serum markers of B-complex vitamins status and kynurenine pathway, as well as decreased number of Treg cells

Cognitive stimulations effects and Taigeiko in elderly women's cognition: an intervention / Los efectos de estímulos cognitivos y Taigeiko en la cognición de idosas: una intervención / Efeitos de estímulos cognitivos e Taigeiko na cognição de idosas: uma intervenção

ABSTRACT Objective: To evaluate the effectiveness of an intervention through cognitive stimulation associated with Taigeiko practice in memory performance and executive function of elderly women, compared to a group exposed to Taigeiko alone. Method: A quasi-experimental study was performed with 16 elderly women. 10 were allocated to the experimental group (EG) submitted to 16 sessions of cognitive stimulation and Taigeiko, and 6 elderly women in the control group (CG) submitted to Taigeiko alone. Cognition was assessed before and after intervention by the tests: Rey Auditory-Verbal Learning (RAVLT); Rey-Osterrieth Complex Figure Test; Trail-Making Test; Stroop Effect; Digit Span Test and Semantic Verbal Fluency Test. Results: Both groups presented differences in RAVLT domains (EG p=0.004, CG p=0.005) and Stroop Effect (EG p=0.012; CG p=0.024). However, in EG, better scores were shown in the tests, although not statistically significant. Conclusion: Taigeiko has been shown to be a potential activity in obtaining cognitive gains, independently of the associated cognitive stimulation.

Promoting fruit and vegetable consumption: Methodological protocol of a randomized controlled community trial.

This study aimed to develop community educational activities in Brazilian primary health care settings. A randomized controlled community trial was conducted to encourage fruit and vegetable consumption (FV-RCT) in a representative sample of consumers aged 20 years or older in a Brazilian city. The fruit and vegetable consumption was classified according to the transtheoretical model's stages of change, reflecting different degrees of readiness for change. The educational activities were based on the transtheoretical model and a problematizing-dialogic pedagogy, planned by an interdisciplinary team, using information collected in a qualitative pilot study. The actions were conducted over seven months, and baseline data were collected from 1483 participants. The educational strategies included workshops interspersed with motivational messages conveyed via postcard, interactive environment-based activities, and informative material. In the workshops, different techniques were used - conversation circles, image theatre, self-portraits, cooking and art as experience. The applied intervention based on the chosen theories implied in a refinement of the intervention, but, nevertheless, proved to be feasible for large population groups and to the scenario of health services. Thus, this interdisciplinary FV-RCT study represents an effort to advance methodological issues and provide theoretical subsidies for actions.

Jump gymnastic at school physical education for adolescents and adults: changes and prevalence of success in health-related physical fitness / Ginástica "Jump" na Educação Física escolar para adolescentes e adultos: alterações e prevalência de sucesso na aptidão física relacionada à saúde

This study aimed to verify changes and prevalence of success in health-related physical fitness after an intervention with jump gymnastic at physical education classes for adolescents and adults according to gender. Thirty-nine adolescents and adults (20 women) were selected for convenience, aged between 15-61 years old, at a school in Charqueadas, Rio Grande do Sul, Brazil. The intervention consisted on 60 Jump gymnastic classes, three times per week in a school semester. The body mass index (BMI); waist circumference (WC); cardiorespiratory fitness (CRF); flexibility and abdominal strength were evaluat-ed. The changes and the prevalence of success were calculated according to specific cutoff points for the individual pre- and post-test variation (D%; mean) and Manova analysis was adopted as comparison test for means variation between gender and variation of this groups at time. BMI have not changed (D = -1.17%, p = 0.123) in women, however it increased (D = 2.07%, p = 0.035) in men. PC have not changed (female: D = 0.71%, p = 0.341, male: D = 1.09%, p = 0.564). Abdominal strength increased (D = 145.47%, p = 0.001) in women but not in men (D = 12.82%, p = 0.411). The flexibility increased similarly in women (D = 16.07%, p = 0.041) and men (D = 17.32%, p = 0.039) and CRF increased only in women (D = 14.32%; p = 0.028). The individual prevalence of success was 41% in flexibility, 33% in CRF, 23% in abdominal strength, 15% in WC and only 10% in BMI. Women had stronger benefits compared to men with the Jump in physical education, mainly in abdominal strength and CRF

Este estudo objetivou verificar alterações e a prevalência de sucesso na aptidão física relacionada à saúde após intervenção com ginástica "Jump" na educação física escolar para adolescentes e adultos, estratificado por sexo. Selecionou-se, por conveniência, 39 adolescentes e adultos (20 mulheres), de 15 a 61 anos em uma escola de Charqueadas, Rio Grande do Sul, Brasil. A intervenção consistiu em 60 aulas de ginástica "Jump", três vezes por semana em um semestre de educação física. Avaliou-se o índice de massa corporal (IMC); perímetro da cin-tura (PC); aptidão cardiorrespiratória (APCR); flexibilidade e força abdominal. As alterações e a prevalência de sucesso foram calculadas através da variação individual pré-teste para pós-teste (D% média) e a análise de Manova foi adotada como teste de comparação para variações das médias entre gênero e variação desses grupos no tempo. O IMC do sexo feminino não alterou (D = -1,17%; p = 0,123), diferentemente do masculino que aumentou (D = 2,07%; p = 0,035). O PC médio não alterou significativamente (feminino: D = -0,71%; p = 0,341; masculino: D = 1,09%; p = 0,564). A força abdominal feminina aumentou (D = 145,47%; p = 0,001) e o sexo masculino não teve alteração (D = -12,82%; p = 0,411). A flexibilidade aumentou similarmente no sexo feminino (D = 16,07%; p = 0,041) e no masculino (D = 17,32%; p = 0,039) e a APCR aumentou somente no sexo feminino (D = 14,32%; p = 0,028). A prevalência individual de sucesso foi de 41% na flexibilidade, 33% na APCR, 23% na força abdominal, 15% no PC e apenas 10% no IMC. O sexo feminino teve maiores bene-fícios em relação ao masculino com o Jump na educação física, principalmente na força abdominal e na APCR

Drinking water and rural schools in the Western Amazon: an environmental intervention study.

BACKGROUND: Although water and sanitation are considered human rights, worldwide approximately three of 10 people (2.1 billion) do not have access to safe drinking water. In 2016, 5.6 million students were enrolled in the 34% of Brazilian schools located in rural areas, but only 72% had a public water supply network. The objective was to evaluate effectiveness of environmental intervention for water treatment in rural schools of the Western Amazonia, and determine the efficacy of water treatment using a simplified chlorinator on potability standards for turbidity, fecal coliforms and Escherichia coli. METHODS: A simplified chlorinator was installed for treatment of potable water in 20 public schools in the rural area of Rio Branco municipality, Acre state, Brazil. RESULTS: Before the intervention, 20% (n = 4), 100% (n = 20) and 70% (n = 14) of schools had water that failed to meet potability standards for turbidity, fecal coliforms and E. coli, respectively. However, after intervention, 70% (p = 0.68), 75% (p < 0.001) and 100% (p < 0.001) of schools complied with potability standards. DISCUSSION: This intervention considerably improved schools' water quality, thus decreasing children's health vulnerability due to inadequate water. Ancillary activities including training, educational lectures, installation of equipment, supply of materials and supplies (65% calcium hypochlorite and reagents) were considered fundamental to achieving success full outcomes. Installation of a simplified chlorinator in rural schools of the Western Amazon is therefore proposed as a social technology aiming at social inclusion, as well as economic and environmental sustainability.

Studies About Physical Activity Interventions Including Follow-Up Analysis: A Systematic Review.

BACKGROUND: Some studies have used the follow-up method to analyze real behavioral changes in research involving physical activity (PA) interventions. This has great scientific value; however, it is hard to apply without satisfactory resources and research funding. Little is known about how many studies have used this method to analyze PA interventions in low-income and middle-income countries, especially Brazil. PURPOSE: To describe Brazilian studies using follow-up analysis after PA interventions. METHODS: A systematic review was performed including Brazilian studies with follow-up analysis after PA interventions; the analyzed papers were from the previous 10 years. The search was carried out in Portuguese, English, and Spanish in the following databases: SciELO, Latin American and Caribbean Health Science Literature, PubMed, and Scopus. The Preferred Reporting Items for Systematic Review and Meta-Analysis method was used. RESULTS: In total, 6 of the 7 studies analyzed were from the southeast region, with the intervention time ranging from 2 to 12 months, carrying out follow-up every 5.3 months with 2.2 observations on average. The interventions had a behavioral approach and were generally carried out in universities, hospitals, and ambulatory care. CONCLUSION: Studies on PA interventions using follow-up analysis are scarce. Considering the relevance of follow-up studies to measure behavior changes, the results suggest that more studies about this topic are essential in Brazil.
