Increasing Health Behaviors and Psychological Measures with an Adapted Version of the ACCELERATION Program.

BACKGROUND: Recent evidence highlights the importance of interventions tackling physical inactivity and unhealthy eating in lower-income countries. The purpose of this study was to examine the effectiveness of the Canadian ACCELERATION lifestyle program adapted to Brazilians. The main outcomes of the study were changes in the engagement in weekly moderate-to-vigorous physical activity (MVPA) and in the daily consumption of fruits/vegetables. METHODS: The adapted intervention consisted of a 12-week quasi-randomized controlled trial delivered through email. The data from the original Canadian experimental group (CE, n = 194) and the two groups of Portuguese-speaking Brazilians living in Canada in the adapted program - Brazilian experimental (BE, n = 41) and Brazilian control (BC, n = 35) - were assessed at baseline and post-intervention. The data of the 270 participants were analyzed using two-way repeated measures factorial ANCOVA (group x time) for ratio variables and Chi-square and McNemar tests for the categorical variables. RESULTS: The BE group had a significant increase in MVPA (mean difference, 95% CI: 86.3, 38.1-134.4 min/week) and fruits/vegetables intake (3.2, 1.4-5.1 servings/day) after the intervention (both p < 0.001). The proportion of participants engaging in ≥ 150 min of MVPA increased from 4.9% to 73.2%, while adoption of a healthy diet increased from 4.9% to 53.7% in the BE group (both p < 0.001). The CE group also improved on these variables (p < 0.05) with no difference vs the BE group (p > 0.05), whereas BC did not show changes (p > 0.05). CONCLUSION: The Brazilian version of the ACCELERATION program effectively promoted positive health behavior changes in its participants and has the potential to contribute to the fight against risk factors for chronic diseases in Brazilians.

Exploring self-care practices and health beliefs among men in the context of emerging infectious diseases: Lessons from the Mpox pandemic in Brazil.

Our goal was to explore self-care practices among men who have sex with men in the context of Mpox in Brazil. This study used qualitative research methods, including interviews and thematic analysis, to collect and analyze data from male participants across the Brazilian territory. The narratives unveil men's perspectives on self-care, risk reduction, and health beliefs during the Mpox pandemic. Our findings highlight a multifaceted approach to self-care among men, encompassing hygiene, physical contact management, mask usage, skin lesion vigilance, and adherence to official guidelines. Men's attitudes toward sexual behaviors emphasize the importance of reducing sexual partners, practicing safe sex, and combating misinformation through accurate information dissemination. The development of these behaviors and self-care practices can be facilitated by nurses guided by Dorothea Orem's Self-Care Theory, supported by patient-centered care, with strategies to address and confront the stigma associated with the disease and provide emotional support. Thus, the study underscores the pivotal role of self-care in mitigating infection risks, especially in the context of emerging infectious diseases. It acknowledges the impact of socio-cultural factors and healthcare policies on men's preventive measures. However, it also recognizes limitations, such as potential bias due to stigma concerns and a nonrepresentative sample. Ultimately, the research advocates for tailored education, promotion of gender equity, and healthcare empowerment to effectively manage health risks in such contexts.

Managing long COVID symptoms and accessing health services in Brazil: A grounded theory analysis.

Background: The worldwide community has shown significant interest in researching the management of Long COVID. However, there is scarce evidence about the daily experiences of people living with Long COVID and their insights into the healthcare services provided to them. Aims: This study aims to understand the experience of Long COVID sufferers with their symptoms and in accessing health services. Method: We employed Charmaz's grounded theory methodology, informed by constructivism, and applied the COREQ guidelines for qualitative research. Sixty-six Brazilians living with Long COVID participated in the study. The data was collected using semi-structured telephone interviews and analyzed using a constant comparative process. Findings: The findings refer firstly to the consequences of persistent Long COVID symptoms. Secondly, they describe how the disease trajectory required Long COVID sufferers to reorganize their routines and develop adaptive strategies. Lastly, they reflect a diverse array of both positive and negative interactions inside the healthcare system conveyed by individuals suffering from Long COVID. These elements converge towards the core category of the study: "The limbo of Long COVID sufferers: between the persistence of symptoms and access to health services". Conclusions: Long COVID is characterized by its varied nature, including a range of physical and emotional repercussions experienced by individuals. There is a need for enhanced comprehension and discourse about Long COVID across several domains, including the general public, policy-making entities, and healthcare professionals. In this sense, the development of specialized services or the reinforcement of existing services to support long COVID sufferers is imperative.

Comparison of 1-year survival between patients initiating chronic hemodialysis under public and private health insurance: register-based data analysis from Brazil.

PURPOSE: Brazil has one of the world's highest numbers of patients on hemodialysis (HD). Most dialysis centers are private and perform HD for patients with private and public health insurance. We compared 1-year survival between patients initiating chronic HD with public and private health insurance. METHODS: This is an HD register-based retrospective cohort. Adult patients starting HD from January 2011 to December 2021 were included. Survival analysis was stratified according to the period entered in the HD register. Multivariate Cox regression focused on 1-year survival differences between private and public patients. RESULTS: In the final sample (n = 5114), 68.5% of participants had public and 31.3% to private health insurance, with overall 1-year survival of 92.8% and 89.9%, respectively (p = 0.002). Crude analysis showed a slightly higher survival rate among patients with public health insurance than those with private health insurance (91 vs. 87%, p = 0.030) in the first period (2019-21). However, the adjusted hazard ratio (HR) did not remain significantly higher for patients with private health insurance compared to those with public health insurance (HR = 1.07; 95% CI 0.80-1.41; p = 0.651), even after propensity score matching of the groups by several baseline features. CONCLUSION: Brazilian chronic HD patients funded by either private health plans or the public system have a similar 1-year mortality risk after controlling for several sociodemographic and clinical parameters.

Temporal trends and spatial clusters of high risk for maternal death due to COVID-19 pre and during COVID-19 vaccination in Brazil: a national population-based ecological study.

OBJECTIVE: This study comprehensively analyzed the temporal and spatial dynamics of COVID-19 cases and deaths within the obstetric population in Brazil, comparing the periods before and during mass COVID-19 vaccination. We explored the trends and geographical patterns of COVID-19 cases and maternal deaths over time. We also examined their correlation with the SARS-CoV-2 variant circulating and the social determinants of health. STUDY DESIGN: This is a nationwide population-based ecological study. METHODS: We obtained data on COVID-19 cases, deaths, socioeconomic status, and vulnerability information for Brazil's 5570 municipalities for both the pre-COVID-19 vaccination and COVID-19 vaccination periods. A Bayesian model was used to mitigate indicator fluctuations. The spatial correlation of maternal cases and fatalities with socioeconomic and vulnerability indicators was assessed using bivariate Moran. RESULTS: From March 2020 to June 2023, a total of 23,823 cases and 1991 maternal fatalities were recorded among pregnant and postpartum women. The temporal trends in maternal incidence and mortality rates fluctuated over the study period, largely influenced by widespread COVID-19 vaccination and the dominant SARS-CoV-2 variant. There was a significant reduction in maternal mortality due to COVID-19 following the introduction of vaccination. The geographical distribution of COVID-19 cases and maternal deaths exhibited marked heterogeneity in both periods, with distinct spatial clusters predominantly observed in the North, Northeast, and Central West regions. Municipalities with the highest Human Development Index reported the highest incidence rates, while those with the highest levels of social vulnerability exhibited elevated mortality and fatality rates. CONCLUSION: Despite the circulation of highly transmissible variants of concern, maternal mortality due to COVID-19 was significantly reduced following the mass vaccination. There was a heterogeneous distribution of cases and fatalities in both periods (before and during mass vaccination). Smaller municipalities and those grappling with social vulnerability issues experienced the highest rates of maternal mortality and fatalities.

Exploring the Feasibility of a Cancer Awareness Program for High School Students in a Brazilian School: A Pilot Study.

Cancer is a leading cause of mortality globally and is projected to be the primary cause of death in Brazil by 2030. Yet, for high school students, information and understanding about cancer are primarily offered through standard biology lessons. This study aimed to assess the feasibility of a brief educational intervention related to cancer among high school students in a Brazilian private school. Participants attended a 1-h online session regarding different aspects of cancer. A self-reported questionnaire about the main topics addressed in the session was filled out before [pre] and after [post] the educational intervention and the results were compared by McNemar's chi-square test. From 900 parents invited, 44 (4.9%) responded to the invitation and agreed with their children's participation, and 24 students attended the activity. The questionnaire was easy to fill out for the students and allowed us to measure differences after the educational intervention. The high school students considered the most interesting topics cancer myths and protective/risk factors. The project was feasible and showed easy application and better knowledge after the educational intervention. The main challenge is related to the access to parents to authorize their children's participation. Designing interventions that focus on cancer education might be a viable way to increase prevention and early diagnosis with implications for students, their families, and the community.

Intervention diversity predicts social rehabilitation indicators at discharge in Therapeutic Communities.

INTRODUCTION: The Therapeutic Community Model narrows the gap in substance use disorder's network of assistance in Brazil by offering residential treatment to socially vulnerable populations. Due to a historical lack of evidence-based approaches, the government has established treatment guidelines and has been trying to implement training and monitoring methods. METHOD: This study analysed real-world data from the monitoring system implemented in the largest network of institutions receiving public funds in the State of Sao Paulo. Data came from 8109 records of individuals admitted between 2014 and 2016 in 48 institutions. RESULTS: Results showed that less than half of the sample was exposed to at least one therapeutic activity from each of the recreational, spiritual, educational and selfcare intervention domains, as proposed by the national guidelines. Social rehabilitation outcome (SRO) defined by housing and self-support at discharge was reported by 21 % of the sample, who stayed in residential treatment for 82.6 days in average. More than half completed the therapeutic programme while 27.3 % dropout. Treatment duration and the diversity of the interventions offered were significantly associated with SRO when mutually adjusted. Chances of SRO increased nearly 5 times when residents were offered the full range of intervention domains, even when controlling for treatment duration. Treatment duration increased chances of SRO in a dose-response manner with a threefold increase for stays up to 90 days and over 9 times for stays longer than 90 days. CONCLUSION: Our findings offer evidence to promote treatment guidelines compliance and to pave the way for the implementation of monitoring systems for this modality of treatment in Brazil and abroad.

Germline mutations in BRCA1 and BRCA2 among Brazilian women with ovarian cancer treated in the Public Health System.

BACKGROUND: Germline mutations in BRCA1 and BRCA2 genes are among the main causes of hereditary ovarian cancer. Identifying these mutations may reduce cancer risk, facilitate early detection, and enable personalized treatment. However, genetic testing is limited in the Brazilian Public Health System, and data regarding germline mutations in many regions are scarce. Therefore, the study aimed to investigate the prevalence of germline mutations in BRCA1 and BRCA2 in women with ovarian cancer treated in the Public Health System in Pernambuco, Brazil. METHODS: A cross-sectional study was conducted in the Hereditary Cancer Program from two reference oncological centers in Pernambuco. Women (n = 45) with high-grade serous ovarian cancer underwent genetic counseling and DNA sequencing for BRCA1 and BRCA2 genes. RESULTS: The prevalence of deleterious mutations in the BRCA1 and BRCA2 genes was 33%. Of the 15 germline mutations found, 13 were in BRCA1 and 2 in BRCA2; two mutations of unknown clinical significance were also found in BRCA2. Mutations c.5266dupC and c.2215 A > T were the most frequent; each was mutation observed in three patients. Additionally, the mutations c.7645dupT and c.921dupT were reported for the first time. CONCLUSION: One in three women showed a pathogenic mutation, demonstrating a significant prevalence of germline mutations in this sample. Additionally, the small sample revealed an interesting number of mutations, indicating the need to explore more regions of the country.

KPC-2-producing Enterobacterales from ready-to-eat food to hospitalized patients.

Foodstuffs are a well-documented source of multidrug-resistant bacteria, and hospitalized patients are usually susceptible to hospital infections owing to their immune status. Therefore, this study aimed to investigate the presence of beta-lactamase-producing Enterobacterales in ready-to-eat foods consumed by hospitalized patients. For this purpose, 51 vegetable and meat samples were collected over 2 months and analyzed. Enterobacterales isolates were identified and subjected to antimicrobial susceptibility testing, followed by beta-lactamase gene screening, pH tolerance assays, and whole-genome sequencing (WGS). Isolates harboring genes encoding extended-spectrum beta-lactamases, cephalosporinases, or carbapenemases were detected, and all isolates tolerated pH levels similar to those in the human gastrointestinal tract. The blaKPC-2 carriers were characterized by WGS and lineages closely related to those causing human infections were identified. These results showed that dietary intake is an alternative route for the transmission of antimicrobial-resistant bacteria, which must be considered when designing effective strategies for infection control.

Thinking Outside the Box: The Interventional Surgeon.

Advances in treatment of structural heart disease have been disruptive to cardiovascular surgery, and there have been discussions about how to incorporate these technologies into the surgeons' therapeutic arsenal. Transcatheter procedures, complex redo interventions, and endovascular aortic approaches are already practiced by cardiovascular surgeons in Brazil. The expansion of these techniques, coupled with recent changes in the country's medical residency program in cardiovascular surgery, has led to an urgent need to acquire catheter-based skills. In this article, we discuss these aspects in the light of the reality of cardiovascular surgery training in Brazil.

Clinical, neuroimaging and genetic findings in Brazilian patients with neurodegeneration with brain iron accumulation.

Neurodegeneration with brain iron accumulation (NBIA) encompasses a clinically and genetically heterogeneous group of rare disorders. Here, we report clinical, neuroimaging and genetic studies in twenty three Brazilian NBIA patients. In thirteen subjects, deleterious variants were detected in known NBIA-causing genes (PANK2, PLA2G6, C9ORF12, WDR45 and FA2H), including previously unreported variants in PANK2 and PLA2G6. Two patients carried rare, likely pathogenic variants in genes not previously associated with NBIA: KMT2A c.11785A > C (p.Ile3929Leu), and TIMM8A c.127T > C (p.Cys43Arg), suggesting an expansion of their associated phenotypes to include NBIA. In eight patients the etiology remains unsolved, suggesting variants undetectable by the adopted methods, or the existence of additional NBIA-causing genes.

Mental Health Collaborative Care in Brazil and the Economy of Attention: Disclosing Barriers and Therapeutic Negotiations.

The introduction of mental health collaborative care (MHCC) is one of the strategies to scale up access to mental health care in primary health care in Brazil. This article investigates an experience of mental health collaborative care in the city of Rio de Janeiro, Brazil. It is a qualitative study involving interviews with physicians and mental health professionals working in primary health care units located in the northern part of the city of Rio de Janeiro, Brazil. The aim is to examine the various strategies and negotiations that primary health care professionals deploy to identify mental distress and plan health care interventions. We discuss the results within the economy of attention framework. We argue that divergences in diagnostic design and therapeutic planning carried out by professionals and users or observed in MHCC meetings illustrate the health-disease-care seeking phenomenon as a negotiated process, entangled in complex interactions. Our results evince that those interactions are not always evident and configure 'what is at stake' in mental suffering. The incorporation of cultural and structural determinants in collaborative care may enable the expansion of mental health initiatives sensitive to local needs and realities.

Epidemiological Insights into Feline Leukemia Virus Infections in an Urban Cat (Felis catus) Population from Brazil.

Feline leukemia virus (FeLV) is a retrovirus distributed worldwide in domestic cats and with different outcomes (progressive, regressive, abortive, focal). The present study reports an epidemiological survey of FeLV frequency and the evaluation of some risk factors and the two main disease outcomes (progressive and regressive) in an urban cat population from Brazil. A total of 366 cats with sociodemographic information and p27 FeLV antigen test performed were included in the study. FeLV DNA (provirus) in the blood samples of all cats was detected via real-time polymerase chain reaction (qPCR). Plasma samples from 109 FeLV-positive and FeLV-negative cats were also submitted to reverse transcription (RT-qPCR) to determine the FeLV viral load. The results demonstrated that 112 (30.6%) cats were positive through the p27 antigen and/or qPCR. A risk factor analysis demonstrated that cats without vaccination against FeLV (OR 9.9, p < 0.001), clinically ill (OR 2.9, p < 0.001), with outdoors access (OR 2.7, p < 0.001), and exhibiting apathetic behavior (OR 3.1, p < 0.001) were more likely to be infected with FeLV. FeLV-infected cats were also more likely to present with anemia (OR 13, p < 0.001) and lymphoma (OR 13.7, p = 0.001). A comparative analysis of the different detection methods in a subset of 109 animals confirmed FeLV infection in 58 cats, including 38 (65.5%) with progressive, 16 (27.6%) with regressive, and 4 (6.9%) with probably focal outcome diseases. In conclusion, this study demonstrates a high prevalence of FeLV in this urban cat population from Brazil and highlights the need to establish more effective prevention strategies (such as viral testing, vaccination programs, specific care for FeLV-positive cats) to reduce diseases associated with this virus in Brazil.

Migration process of Venezuelan women to Brazil: living conditions and use of health services in Manaus and Boa Vista, 2018-2021.

BACKGROUND: The last decade saw the emergence of a new significant migration corridor due to the mass migration of Venezuelans to neighboring countries in South America. Since 2018, Brazil became the third host country of Venezuelan displaced populations. Little is known about how migratory processes affect needs, access to social programs, and public health services of migrant women. The goal of this study is to shed light on the socio-economic profile, living conditions, and use of health services of Venezuelan migrant women in two main reception cities in Brazil. METHODS: A survey was conducted using respondent-driven sampling (RDS) in the cities of Boa Vista (Roraima), and Manaus (Amazonas). The study included 2012 Venezuelan migrant women aged between 15 and 49 years old who migrated from Venezuela to Brazil between 2018 and 2021. Relative prevalence was calculated, and the χ2 test was used to analyse the homogeneity of proportions. All analyses considered the complex sampling. RESULTS: The main reasons for migrating relate to difficulties obtaining food (54%) and accessing health services (37.8%) in their country of origin. They were young and mixed race (65.7%) and had high school education (69.9%). In Manaus, 3.7% of the interviewees declared that they had no family income in the last month, while in Boa Vista, it was higher (66.2%) (p-value < 0.001). Almost one-third of them sought health care in the last 15 days, and 95% of them received care. The residents of Boa Vista arrived more recently and family income and access to paid work improved with time of residence in Brazil. CONCLUSIONS: Given the increasing flow of Venezuelan migrants crossing to Brazil, a reception system was established for the provision of food, shelter, access to health services, and income transfer programs to migrants. This was the case despite high unemployment and poverty levels and income inequality, particularly in the city of Boa Vista. However, the majority had legal migrant status and had access to the public and universal healthcare system in Brazil (SUS). The use of the SUS was similar in both cities, acting as a buffer for the differences in opportunities offered.

Discriminatory experiences among gay, bisexual, and other men who have sex with men, and transgender and non-binary individuals: a cross sectional analysis.

Background: Several systems of oppression combine in complex ways to impact the lives of minority populations. Following an intersectionality framework, we assessed the frequency and perceived reasons for discrimination among gay, bisexual, and other cisgender men who have sex with men (MSM) and transgender and non-binary individuals (TGNB), stratified by race. Methods: Online survey among MSM and TGNB ≥18 years living in Brazil, between November/2021 and January/2022. We used the 18-item Explicit Discrimination Scale to assess day-to-day experiences of differential treatment, and perceived discrimination. For each item, participants indicated their perceived reasons for differential treatment using 14 pre-defined options. Negative binomial regression models assessed if race was a significant predictor of discrimination. Subsequent models, stratified by race, examined associations of perceived reasons and number of reasons with perceived discrimination. Findings: Of 8464 MSM and TGNB, 4961 (58.6%) were White, 2173 (25.7%) Pardo (Brazil's official term for admixed populations), and 1024 (12.1%) Black. Black participants' scores for perceived discrimination (mean, standard deviation) were higher (10.2, 8.8) [Pardo (6.5, 6.8), White (5.2, 5.7)], and race was both the main reason for and the strongest predictor of perceived discrimination. The number of reasons participants used to interpret their discriminatory experiences was also a predictor of discrimination score among White, Pardo, and Black participants. Interpretation: LGBTQIA+phobia was highly prevalent among all participants. Additionally, our results indicated that Black MSM and TGNB participants were more frequently discriminated against than other racial groups, with racial discrimination uniquely contributing these experiences.

The global diet quality score as an indicator of adequate nutrient intake and dietary quality - a nation-wide representative study.

BACKGROUND: The Global Diet Quality Score (GDQS) was developed to be a simple, timely and cost-effective tool to track, simultaneously, nutritional deficiency and non-communicable disease risks from diet in diverse settings. The objective was to investigate the performance of GDQS as an indicator of adequate nutrient intake and dietary quality in a national-representative sample of the Brazilian population. METHODS: Nationally-representative data from 44,744 men and non-pregnant and non-lactating women aging ≥ 10 years, from the Brazilian National Dietary Survey were used. Dietary data were collected through two 24-h recalls (24HR). The GDQS was calculated and compared to a proxy indicator of nutrient adequate intake (the Minimum Dietary Diversity for Women-MDD-W) and to an indicator of high-risk diet for non-communicable diseases (caloric contribution from ultra-processed foods-UPF). To estimate the odds for overall nutrient inadequacy across MDD-W and GDQS quintiles, a multiple logistic regression was applied, and the two metrics' performances were compared using Wald's post-test. RESULTS: The mean GDQS for Brazilians was 14.5 (0-49 possible range), and only 1% of the population had a low-risk diet (GDQS ≥ 23). The GDQS mean was higher in women, elderly individuals and in higher-income households. An inverse correlation was found between the GDQS and UPF (rho (95% CI) = -0.20(-0.21;-0.19)). The odds for nutrient inadequacy were lower as quintiles of GDQS and MDD-W were higher (p-trend < 0.001), and MDD-W had a slightly better performance than GDQS (p-diff < 0.001). Having a low-risk GDQS (≥ 23) lowered the odds for nutrient inadequacy by 74% (95% CI:63%-81%). CONCLUSION: The GDQS is a good indicator of overall nutrient adequacy, and correlates well with UPF in a nationally representative sample of Brazil. Future studies must investigate the relationship between the GDQS and clinical endpoints, strengthening the recommendation to use this metric to surveillance dietary risks.

Cost-effectiveness of early intervention in psychosis in low- and middle-income countries: economic evaluation from São Paulo, Brazil.

AIMS: The effectiveness and cost-effectiveness of early intervention for psychosis (EIP) services are well established in high-income countries but not in low- and middle-income countries (LMICs). Despite the scarcity of local evidence, several EIP services have been implemented in LMICs. Local evaluations are warranted before adopting speciality models of care in LMICs. We aimed to estimate the cost-effectiveness of implementing EIP services in Brazil. METHODS: A model-based economic evaluation of EIP services was conducted from the Brazilian healthcare system perspective. A Markov model was developed using a cohort study conducted in São Paulo. Cost data were retrieved from local sources. The outcome of interest was the incremental cost-effectiveness ratio (ICER) measured as the incremental costs over the incremental quality-adjusted life-years (QALYs). Sensitivity analyses were performed to test the robustness of the results. RESULTS: The study included 357 participants (38% female), with a mean (SD) age of 26 (7.38) years. According to the model, implementing EIP services in Brazil would result in a mean incremental cost of 4,478 Brazilian reals (R$) and a mean incremental benefit of 0.29 QALYs. The resulting ICER of R$ 15,495 (US dollar [USD] 7,640 adjusted for purchase power parity [PPP]) per QALY can be considered cost-effective at a willingness-to-pay threshold of 1 Gross domestic product (GDP) per capita (R$ 18,254; USD 9,000 PPP adjusted). The model results were robust to sensitivity analyses. CONCLUSIONS: This study supports the economic advantages of implementing EIP services in Brazil. Although cultural adaptations are required, these data suggest EIP services might be cost-effective even in less-resourced countries.

Challenges and opportunities for access to Advanced Therapy Medicinal Products in Brazil.

BACKGROUND AIMS: The marketing authorization of Advanced Therapy Medicinal Products (ATMPs) in Brazil is recent. The features of these therapies impose specialized regulatory action and are consequently challenging for developers. The goal of this study was to identify the industry's experience in clinical development, marketing authorization and access to ATMPs through the Unified Health System (SUS, acronym in Portuguese), from a regulatory perspective. METHODS: A survey containing structured questions was conducted among research participants who work at companies that commercialize ATMPs. A descriptive analysis was performed. RESULTS: We invited 15 foreign pharmaceutical companies, of which 10 agreed to participate. Overall, participants assessed that Brazil has a well-established regulatory system, especially the sanitary registration by the National Health Surveillance Agency (Anvisa), which ensures the quality, safety, and efficacy of the products. The Agency's good interaction with the regulated sector, the harmonization of sanitary and ethical assessment systems with other countries, and the analysis time in the biosafety assessment of Genetically Modified Organisms (GMOs) stand out as positive in industry's evaluation. On the other hand, it is important to advance the pricing regulation for these products since Brazilian regulations do not establish specific criteria for ATMP. One of the biggest challenges is the difficulty for the SUS in reimbursing these very high-cost therapies, especially using current Health Technology Assessment (HTA) methods. CONCLUSIONS: Considering the increasing number of approvals of cell and gene therapies in Brazil in the coming years, a close dialogue between the industry and the public sector is recommended to advance regulatory improvements (pricing and HTA). Additionally, the construction of policies to promote the national Health Economic-Industrial Complex, based on a mission-oriented vision that encourages innovative models of financing, especially those that consider risk-sharing and co-financing technologies, will help provide the population with universal, equitable and sustainable access to ATMP in the SUS.

A nationwide study on immunosenescence biomarkers profile in older adults: ELSI-Brazil.

Immunosenescence is a phenomenon caused by changes in the immune system, and part of these changes involves an increase in circulating immunological biomarkers, a process known as "Inflammaging." Inflammaging can be associated with many diseases related to older people. As the older population continues to grow, understanding changes in the immune system becomes essential. While prior studies assessing these alterations have been conducted in countries with Caucasian populations, this investigation marks a pioneering effort. The object of the study is to describe for the first time that the distribution of cytokines, chemokines, and growth factors serum levels, assessed by Luminex platform, has been examined in a Brazilian population-based study of older adult females and males by age. Blood samples from 2111 participants (≥50 years old) were analyzed at the baseline (2015/2016) of the ELSI-Brazil study. The exploratory variables considered in the study were age, sex, educational level, residence area, geographic region, alcohol and smoking consumption, physical activity, and self-reported medical diagnoses of hypertension, diabetes, asthma, arthritis, and cancer. The association between serum biomarker levels and age was assessed by a quantile regression model adjusted in the total population and stratified by sex. The significance level considered in the analysis was 0.05. The mean age of the participants was 62.9 years, with a slight majority of female (52.7 %). Differences were found between the sexes in the median circulating levels of the CCL11, CXCL10, and FGF biomarkers. Eight biomarkers showed significant associations with age, including the pro-inflammatory CXCL10, TNF-α, IL-6, IL-17, and IL-2; and type 2/regulatory CCL11 and IL-4, showing positive associations, and anti-inflammatory IL-1Ra showing a negative association. The results suggest similar associations between the sexes, revealing an inflammatory profile characterized by types 1 and 2. Remarkably, these findings reinforce the concept of the Inflammaging process in Brazilian population. These findings add novel insights to about the immunosenescence aspects in middle-income countries and help define biomarkers capable of monitoring inflammation in older adults.

Empirical modeling of agricultural climate risk.

Effective policies for adaptation to climate change require understanding how impacts are related to exposures and vulnerability, the dimensions of the climate system that will change most and where human impacts will be most draconian, and the institutions best suited to respond. Here, we propose a simple method for more credibly pairing empirical statistical damage estimates derived from recent weather and outcome observations with projected future climate changes and proposed responses. We first analyze agricultural production and loan repayment data from Brazil to understand vulnerability to historical variation in the more predictable components of temperature and rainfall (trend and seasonality) as well as to shocks (both local and over larger spatial scales). This decomposed weather variation over the past two decades explains over 50% of the yield variation in major Brazilian crops and, critically, can be constructed in the same way for future climate projections. Combining our estimates with bias-corrected downscaled climate simulations for Brazil, we find increased variation in yields and revenues (including more bad years and worse outcomes) and higher agricultural loan default at midcentury. Results in this context point to two particularly acute dimensions of vulnerability: Intensified seasonality and local idiosyncratic shocks both contribute to worsening outcomes, along with a reduced capacity for spatially correlated ("covariate") shocks to ameliorate these effects through prices. These findings suggest that resilience strategies should focus on institutions such as water storage, financial services, and reinsurance.
