Service Function Chain Placement in Distributed Scenarios: A Systematic Review

Abstract: The network function virtualization (NFV) paradigm is an emerging technology that provides network flexibility by allowing the allocation of network functions over commodity hardware, like legacy servers in an IT infrastructure. In comparison with traditional network functions, implemented by dedicated hardware, the use of NFV reduces the operating and capital expenses and improves service deployment. In some scenarios, a complete network service can be composed of several functions, following a specific order, known as a service function chain (SFC). SFC placement is a complex task, already proved to be NP-hard. Moreover, in highly distributed scenarios, the network performance can also be impacted by other factors, such as traffic oscillations and high delays. Therefore, a given SFC placement strategy must be carefully developed to meet the network operator service constraints. In this paper, we present a systematic review of SFC placement advances in distributed scenarios. Differently from the current literature, we examine works over the last 10 years which addressed this problem while focusing on distributed scenarios. We then discuss the main scenarios where SFC placement has been deployed, as well as the several techniques used to create the placement strategies. We also present the main goals considered to create SFC placement strategies and highlight the metrics used to evaluate them.

Machine learning and deep learning techniques to support clinical diagnosis of arboviral diseases: A systematic review

Abstract: Neglected tropical diseases (NTDs) primarily affect the poorest populations, often living in remote, rural areas, urban slums or conflict zones. Arboviruses are a significant NTD category spread by mosquitoes. Dengue, Chikungunya, and Zika are three arboviruses that affect a large proportion of the population in Latin and South America. The clinical diagnosis of these arboviral diseases is a difficult task due to the concurrent circulation of several arboviruses which present similar symptoms, inaccurate serologic tests resulting from cross-reaction and co-infection with other arboviruses.The goal of this paper is to present evidence on the state of the art of studies investigating the automatic classification of arboviral diseases to support clinical diagnosis based on Machine Learning (ML) and Deep Learning (DL) models.We carried out a Systematic Literature Review (SLR) in which Google Scholar was searched to identify key papers on the topic. From an initial 963 records (956 from string-based search and seven from a single backward snowballing procedure), only 15 relevant papers were identified.Results show that current research is focused on the binary classification of Dengue, primarily using tree-based ML algorithms. Only one paper was identified using DL. Five papers presented solutions for multi-class problems, covering Dengue (and its variants) and Chikungunya. No papers were identified that investigated models to differentiate between Dengue, Chikungunya, and Zika.The use of an efficient clinical decision support system for arboviral diseases can improve the quality of the entire clinical process, thus increasing the accuracy of the diagnosis and the associated treatment. It should help physicians in their decision-making process and, consequently, improve the use of resources and the patient's quality of life.

Nursing professionals' biosafety in confronting COVID-19.

Abstract: Objective: To investigate the nursing professionals' biosecurity in confronting COVID-19. Methods: This is a Survey type study. Nursing professionals were invited via messaging apps, using self-applied data collection forms. The sample selection (n=693) was non-probabilistic. A descriptive data analysis was conducted. Results: considering the biosafety aspects in facing COVID-19, 79.0% of the participants had not received training or considered it insufficient, 69.3% reported the lack of personal protective equipment during work, and 81.8% did not feel safe with the internal flux adaptations for handling COVID-19 cases. Conclusion: Continuous and effective nursing team training and personal protective equipment availability are necessary, as well as internal flow adjustments for attending suspected or confirmed cases.

Blenderized tube feeding for children: an integrative review.

Abstract: Objective: To analyze scientific evidence on the use of blenderized tube feeding in children regarding nutritional composition, family satisfaction, and health outcomes. Data source: Survey was conducted in the PubMed, Scopus, Embase, and Virtual Health Library (VHL) databases using the following search terms: blenderized tube feeding OR blended tube feeding OR homemade OR pureed AND enteral nutrition AND enteral tube. The methodological quality of the selected articles was evaluated using the Critical Appraisal Skill Programme and Hierarchical Classification of Evidence. Data synthesis: After analysis, 11 articles were included in the present review. Most studies demonstrated improvements in health outcomes and greater family satisfaction after replacing the commercial enteral feeding with blenderized tube feeding. Conclusions: When guided and monitored by the healthcare team, a blenderized tube feeding ensures an adequate nutritional composition. The use of this method is also associated with positive health outcomes such as reductions in gastrointestinal symptoms and hospitalizations. Moreover, a high frequency of family satisfaction was verified.%

Biomass and vegetation index by remote sensing in different caatinga forest areas

Abstract: Continued unsustainable exploitation of natural resources promotes environmental degradation and threatens the preservation of dry forests around the world. This situation exposes the fragility and the necessity to study landscape transformations. In addition, it is necessary to consider the biomass quantity and to establish strategies to monitor natural and anthropic disturbances. Thus, this research analyzed the relationship between vegetation index and the estimated biomass using allometric equations in different Brazilian caatinga forest areas from satellite images. This procedure is performed by estimating the biomass from 9 dry tropical forest fragments using allometric equations. Area delimitations were obtained from the Embrapa collection of dendrometric data collected in the period between 2011 and 2012. Spectral variables were obtained from the orthorectified images of the RapidEye satellite. The aboveground biomass ranged from 6.88 to 123.82 Mg.ha-1. SAVI values were L = 1 and L = 0.5, while NDVI and EVI ranged from 0.1835 to 0.4294, 0.2197 to 0.5019, 0.3622 to 0.7584, and 0.0987 to 0.3169, respectively. Relationships among the estimated biomass and the vegetation indexes were moderate, with correlation coefficients (Rs) varying between 0.64 and 0.58. The best adjusted equation was the SAVI equation, for which the coefficient of determination was R² = 0.50, R2aj = 0.49, RMSE = 17.18 Mg.ha-1 and mean absolute error of prediction (MAE) = 14.07 Mg.ha-1, confirming the importance of the Savi index in estimating the caatinga aboveground biomass.

Antinociceptive and anti-inflammatory activities of Hymenaea martiana Hayne (Fabaceae) in mice.

Abstract: Hymenaea martiana is a species popularly known in Northeastern Brazil as “jatoba” and used in folk medicine to treat pain and inflammation. The aim of this work was to evaluate the antinociceptive and anti-inflammatory activity of H. martiana. In the present study, we carried out an investigation about the effects of the crude ethanolic extract (Hm-EtOH) and the ethyl acetate fraction (Hm-AcOEt) in models of nociception and inflammation in mice. Chemical (acetic acid-induced writhing and formalin) and thermal stimuli (hot plate) were used for the evaluation of antinociceptive activity, while for the anti-inflammatory profile paw edema induced by carrageenan was used, along with leukocyte migration to the peritoneal cavity. The presence of the flavonoid astilbin in the samples was characterized through HPLC-DAD-MS analysis. Hm-EtOH and Hm-AcOEt (100, 200 and 400 mg.kg-1, i.p.) significantly reduced the number of abdominal contortions and decreased the paw licking time in the formalin test. In the hot plate, the extract increased the latency time of animals. Hm-EtOH and Hm-AcOEt inhibited significantly the increase in the edema after the administration of carrageenan. Hm-EtOH and Hm-AcOEt inhibited leukocyte migration in the peritonitis test. HPLC-DAD-MS analysis of Hm-EtOH and Hm-AcOEt revealed the presence of the flavonoid astilbin in the samples. According to the results of this study, both Hm-EtOH and Hm-AcOEt have antinociceptive and anti-inflammatory activities, which could be related with the presence of flavonoid in the extracts. The results reinforce the popular use of this plant.

Maniçoba for sheep and goats - forage yield, conservation strategies, animal performance and quality of products

Abstract: In dry regions worldwide, providing feed for ruminants has been a great challenge, with a need to use plants which contribute to the resilience of production systems. Manicoba is seen as a potential forage resource in the Brazilian semiarid, being used as hay or silage to feed ruminants. This review summarized results regarding forage production of manicoba, in addition to dry matter (DM) intake, productive performance, and quality of animal products obtained providing manicoba based diets, when compared to diets composed by other roughages for goats and sheep. Considering the evaluated studies, the average yield of manicoba varied from 367 to 1,592 kg DM ha-1, enhancing the forage yield by increasing plant fertilization and planting density. Diets based on manicoba promoted similar or higher intake of DM and productive performance for goats and sheep, when compared to diets comprising other forage resources. The quality of animal products was also similar to the ones obtained with diets based on traditional roughages, such as Tifton 85 hay or spineless cactus. Therefore, manicoba allows a forage production that may contribute to ruminant production systems in semiarid environment and promote productive performance and animal product quality compatible to the ones provided by traditional forage plants.

Validation of SmartVA using conventional autopsy: a study of adult deaths in Brazil

Abstract: Summary Background Accurate cause of death data are essential to guide health policy. However, mortality surveillance is limited in many low-income countries. In such settings, verbal autopsy (VA) is increasingly used to provide population-level cause of death data. VAs are now widely interpreted using the automated algorithms SmartVA and InterVA. Here we use conventional autopsy as the gold standard to validate SmartVA methodology. Methods This study included adult deaths from natural causes in Sao Paulo and Recife for which conventional autopsy was indicated. VA was conducted with a relative of the deceased using an amended version of the SmartVA instrument to suit the local context. Causes of death from VA were produced using the SmartVA-Analyze program. Physician coded verbal autopsy (PCVA), conducted on the same questionnaires, and Global Burden of Disease Study data were used as additional comparators. Cause of death data were grouped into 10 broad causes for the validation due to the real-world utility of VA lying in identifying broad population cause of death patterns. Findings The study included 2,060 deaths in Sao Paulo and 1,079 in Recife. The cause specific mortality fractions (CSMFs) estimated using SmartVA were broadly similar to conventional autopsy for: cardiovascular diseases (46.8% vs 54.0%, respectively), cancers (10.6% vs 11.4%), infections (7.0% vs 10.4%) and chronic respiratory disease (4.1% vs 3.7%), causes accounting for 76.1% of the autopsy dataset. The SmartVA CSMF estimates were lower than autopsy for “Other NCDs” (7.8% vs 14.6%) and higher for diabetes (13.0% vs 6.6%). CSMF accuracy of SmartVA compared to autopsy was 84.5%. CSMF accuracy for PCVA was 93.0%. Interpretation The results suggest that SmartVA can, with reasonable accuracy, predict the broad cause of death groups important to assess a population's epidemiological transition. VA remains a useful tool for understanding causes of death where medical certification is not possible.

Syphilis Trigram: a domain-specific visualisation to combat syphilis epidemic and improve the quality of maternal and child health in Brazil

Abstract: The Brazilian healthcare system is a large and complex system, specially considering its mixed public and private funding. The incidence of syphilis has increased in the last four years, in spite of the presence of an effective and available treatment. Furthermore, syphilis takes part in a group of disorders of compulsory notification to the public health surveillance. The epidemiological implications are especially important during pregnancy since it can lead to complications, related to prematurity stillbirth and miscarriage, in addition to congenital syphilis, characterized by multisystem involved in the newborn.The Action Research methodology was applied to address the complexity of the syphilis surveillance scenario in Pernambuco, Brazil. Iterative learning cycles were used, resulting in six cycles, followed by a formal validation of an operational version of the syphilis Trigram visualisation at the end of the process. The original data source was analyzed and prepared to be used without any new data or change in the ordinary procedure of the current system.The main result of this work is the production of a Syphilis Trigram: a domain-specific infographic for presenting gestational data and birth data. The second contribution of this work is the Average Trigram, an organized pie chart which synthesizes the Syphilis Trigram relationship in an aggregated way. The visualization of both graphics is presented in an Infographic User Interface, a tool that gathers an infographic broad visualization aspect to data visualization. These interfaces also gather selections and filters tools to assist and refine the presented information. The user can experience a specific case-by-case view, in addition to an aggregated perspective according to the cities monitored by the system.The proposed domain-specific visualization amplifies the understanding of each syphilis case and the overall characteristics of cases of a chosen city. This new information produced by the Trigram can help clarify the reinfection/relapse cases, optimize resource allocation and enhance the syphilis healthcare policies without the need of new data. Thus, this enables the health surveillance professionals to see the broad tendency, understand the key patterns through visualization, and take action in a feasible time.

Nurses' performance in palliative care: spiritual care in the light of Theory of Human Caring.

Abstract: Objectives: to analyze nurses’ role in assisting patients in palliative care, with emphasis on the spiritual dimension, in the light of Theory of Human Caring. Methods: this is an exploratory, qualitative study, carried out in a hospital in Joao Pessoa, Paraiba, between August and December 2019, with 10 nurses. For data collection, semi-structured interviews were used. For analysis, we opted for content analysis. Results: the spiritual dimension of care is contemplated by several religious and spiritual practices. These are respected and encouraged by nurses, although there is difficulty in providing care for the spiritual dimension. Final Considerations: nurses have attitudes consistent with Jean Watson’s Theory and apply the Caritas Process elements during assistance to patients’ spiritual dimension in palliative care.

Agreement and accuracy of shear-wave techniques (point shear-wave elastography and 2D-shear-wave elastography) using transient elastography as reference

Abstract: We aimed to evaluate the agreement/accuracy of point shear-wave elastography (p-SWE) and 2D-shear-wave elastography (2D-SWE) for liver fibrosis staging using transient elastography (TE) as the reference.This retrospective study analyzed data from people with chronic liver diseases submitted to TE, p-SWE, and 2D-SWE. Liver fibrosis stages were defined using the TE's 'rule of five': normal (<5 kPa); suggestive of compensated-advanced chronic liver disease (cACLD) (10-15 kPa); highly suggestive of cACLD (15-20 kPa); suggestive of clinically significant portal hypertension (>20 kPa). Agreement and accuracy of p-SWE and 2D-SWE were assessed. Optimal cutoffs for p-SWE and 2D-SWE were identified using the point nearest to the upper left corner of the ROC curves.A total of 289 participants were included. The correlation between TE and 2D-SWE (rho = 0.59; P < 0.001) or p-SWE (rho = 0.69; P < 0.001) was satisfactory. The AUROCs (95% CI) of 2D-SWE and p-SWE for TE ≥ 5 kPa; TE ≥ 10 kPa; TE ≥ 15 kPa and TE ≥ 20 kPa were 0.757 (0.685-0.829) and 0.741 (0.676-0.806); 0.819 (0.770-0.868) and 0.870 (0.825-0.915); 0.848 (0.803-0.893) and 0.952 (0.927-0.978); 0.851 (0.806-0.896) and 0.951 (0.920-0.982), respectively. AUROCs of 2D-SWE were significantly lower compared with p-SWE for detecting cACLD. Optimal thresholds of 2D-SWE and p-SWE for TE ≥ 15 kPa were 8.82 kPa (sensitivity = 86% and specificity = 79%) and 8.86 kPa (sensitivity = 90% and specificity = 92%), respectively.LSM by p-SWE and 2D-SWE techniques were correlated with TE. LSM by p-SWE seems to be more accurate than 2D-SWE to identify patients with more advanced fibrosis.

A three-state opinion formation model for financial markets

Abstract: We propose a three-state microscopic opinion formation model for the purpose of simulating the dynamics of financial markets. In order to mimic the heterogeneous composition of the mass of investors in a market, the agent-based model considers two different types of traders: noise traders and noise contrarians. Agents are represented as nodes in a network of interactions and they can assume any of three distinct possible states. The time evolution of the state of an agent is dictated by probabilistic dynamics that include both local and global influences. A noise trader is subject to local interactions, tending to assume the majority state of its nearest neighbors, whilst a noise contrarian is subject to a global interaction with the behavior of the market as a whole, tending to assume the state of the global minority of the market. The model exhibits the typical qualitative and quantitative features of real financial time series, including distributions of returns with heavy tails, volatility clustering and long-time memory for the absolute values of the returns. The distributions of returns are fitted by means of coupled Gaussian distributions, quantitatively revealing transitions between leptokurtic, mesokurtic and platykurtic regimes in terms of a non-linear statistical coupling which describes the complexity of the system.

Suffering and defense mechanisms: an analysis of the work of Primary Health Care nurses.

Abstract: Objective: To analyze the suffering and coping strategies of nurses working in Primary Health Care considering the psychodynamics of their work. Methods: Descriptive study with a qualitative approach, carried out with 11 nurses working in Primary Health Care. Data were collected through semi-structured interviews, systematized, and interpreted using Bardin’s content analysis method applied to recurrent themes. Results: The suffering factors related to work in Primary Health Care are difficulties with management, the fragile structure of the health support network, and conflicts with the users. Defensive strategies to minimize these difficulties are the support of hierarchical superiors, the empowerment of the community and users, and communication between team members. Final considerations: It is important that there be changes in the organization of this line of work to improve the workers’ health.

Clinical Efficacy of Mouthwashes with Potassium Salts in the Treatment of Dentinal Hypersensitivity: A Systematic Review and Meta-analysis

Abstract: SUMMARY Aim This systematic review and meta-analysis evaluated whether the home use of mouthwashes containing potassium salts is effective in reducing and controlling dentin hypersensitivity (DH). Methods and Materials This study is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist and was registered in PROSPERO (CRD42021228410). Randomized clinical trials evaluating the use of mouthwashes containing potassium salt for daily household mouthwash for at least four weeks to reduce DH compared with a control mouthwash were selected, with no limitation on year of publication. Electronic research was carried out in PubMed/MEDLINE, Scopus, Web of Science, and Cochrane Library by two independent researchers. One hundred thirty-three articles were obtained, and nine were selected according to the inclusion criteria. Results The selected studies evaluated DH through tests of sensitivity to tactile and evaporative stimuli and showed that, for the tactile stimulus, there were no baseline differences between groups (p=0.12; mean difference: −0.33; confidence intervals [CI]: −0.73 to 0.08). However, there were significant differences after two weeks of use (p=0.00001; mean difference: 4.67; CI: 4.53 to 4.81), after four weeks (p=0.00001; mean difference: 13.29; CI: 13.03 to 13.55), and after eight weeks (p=0.00001; mean difference: 8.88; CI: 5.73 to 12.02) favoring the experimental group. The results of the evaporative test showed no differences in the baseline assessment between the two groups (p=0.50; mean difference: −0.02; CI: −0.09 to 0.04), but after four weeks (p=0.00001; mean difference: −0.32; CI: −0.44 to −0.20), and eight weeks of use (p=0.00001; mean difference: −0.42; CI: −0.57 to −0.27) there were differences favoring the experimental group. The incidence of side effects showed no differences between the two groups (p=0.89; mean difference: 1.03; CI: 0.67 to 1.58). Conclusion The daily use of mouthwashes containing potassium salt is effective in the treatment of dentinal hypersensitivity, as a complementary step to brushing at least twice a day for two weeks, four weeks, and up to eight weeks, without presenting side effects.

A new species of the rare deep-sea genus Sciadonus Garman, 1899 (Teleostei, Bythitidae) from off Brazil, with a discussion of the evolution of troglomorphism and miniaturization in the aphyonid clade

Abstract: A new species of the rare, deep-sea genus Sciadonus Garman, 1899 (Bythitidae) is described based on two specimens obtained by the Brazilian R/V Alpha Crucis on the continental slope off São Paulo State, Southeastern Brazil, western South Atlantic. It differs from its congeners by the combination of the following characters: body pale lacking dark pigmentation except for on female claspers; a pair of dermal tissue flaps anteriorly on lower jaw; pelvic-fin rays present; precaudal vertebrae 39 or 40 and total vertebrae 74 or 75. The key to the species of Sciadonus is updated. A discussion of the presence and differentiation between troglomorphic and miniature characteristics among the species in the aphyonid clade is provided and compared with other bythitids.

Traffic-Based Heuristics for Regenerator Placement in Translucent Dynamic Optical Networks

Abstract: We propose in this paper two heuristic strategies to solve the regenerator placement problem (RPP) in translucent networks under dynamic traffic. The heuristics are based on both the forecast of the offered load and estimates of blocking probabilities in the network nodes. The proposed heuristics are compared to other regenerator placement algorithms from the literature in two different topologies. The results show that one of the proposed algorithms outperforms, in the investigated scenarios, all other algorithms from the literature considered for comparison purposes in this paper, whereas the second proposed algorithm outperforms the algorithms from the literature only in some considered scenarios.

Occupational Risks Identification in the Red Ceramics Manufacturing Process

Abstract: Red ceramics manufacturing is a field that is strongly driven by the growth of construction that has great importance within the Brazilian economy. However, the companies involved in the production are usually small and work with outdated technologies, besides the lack of qualification of its workforce. Thus, workers get exposed to precarious working conditions, causing countless accidents. The objective of this study was to identify and evaluate the risks in the red ceramic manufacturing process. The survey embraced eight ceramic companies in northeastern Brazil, with 131 employees. Also, it was applied a checklist with safety items of Brazilian regulations to identify the degree of compliance of these companies. The checklist’s results showed that all companies had safety items in disagreement with Brazilian law. It was possible to confirm that the workplace exposed workers to a high incidence of heat, noise, and dust, besides unprotected machinery, high physical effort, accidents risks, presenting a high degree of risk for workers.

The Future as a Necessity

Abstract: In this chapter, I return to Clarice Lispector’s writing from the vantage point of a contemporary condition that she could not have anticipated—one shaped by ecological anxieties and climate change. The essay explores the hypothesis that her literature’s resistance to redemptive possibilities and expectations of closure provide starting points for reflecting on the Anthropocene’s cultural and aesthetic entanglements. What sort of subjects does the climate crisis forge? Her fiction is full of characters dwelling on the realization that amid “foreclosed futures,” life goes on. Her last novel, The Hour of the Star, for example, in many ways focuses on diasporas of the hopeless or living on borrowed time. A return to Lispector’s intimate imaginaries of the future reveals unintended resonances, inviting a meditation on the unthinkable consequences of climate change.

Urban and Environmental Scales of Belonging in the Digital Age

Abstract: What does it mean to think of Latin American cities as cultural arenas in the internet era and amid planetary urbanization? How have digital forms of cultural mediation and the crises in lettered city paradigms scrambled and reoriented scales of belonging? What if new media supersedes not merely old media, but the very scales of environmental and urban life as we have known them? Can forms of cultural cohesion or common denominators sustain themselves amid the deep inequalities, differences, and expansiveness that mark the region's major metropolitan areas? This essay addresses those questions, among others, drawing on Milton Santos's work, and engaging in reflections about digital media, algorithms, infrastructure, financialization, urbanization, climate change, precarity, architecture, literature, and culture. While maintaining that human experience is bounded by two inevitable scales, the body and the planet, the essay argues that although we should not relinquish a commitment to the irreducibility of human subjectivities to any single or stable set of variables, we might also do well to think more carefully about yearnings for belonging.

Teatro foro : práctica pedagógica alternativa para la formación en ciudadanía y democracia en la educación media

Abstract: El trabajo de grado teatro foro: práctica pedagógica alternativa para la formación en ciudadanía y democracia en la educación media, busca hacer una reflexión crítica sobre el abordaje que la educación pública (básica y media) ha hecho al aprendizaje para la ciudadanía y la democracia. Esta reflexión crítica parte, de un lado, de asumir que el ejercicio de participación política está articulada al ejercicio de la democracia y de manera directa a la formación para la ciudadanía y de otro de observar la forma en que el arte y específicamente el teatro foro -como herramienta pedagógica en los procesos de educación política y participación ciudadana- promueve la acción ciudadana, amplia el concepto de lo político y el papel del ciudadano en la construcción de la sociedad y en su transformación.

Longitudinal association between moderate to vigorous physical activity and lipid profile indicators in adolescents

Abstract: The objective of this study was to examine the association between time engaged in moderate (MPA), vigorous (VPA), and moderate-to-vigorous (MVPA) physical activity (PA) and indicators of lipid profile in adolescents. This longitudinal study with a four-year follow-up, and three collection points (2014, 2015 and 2017) analyzed the data of 136 adolescents (10−13 years old; 53.7% girls), in João Pessoa, Brazil. The time in MPA, VPA and MVPA times was measured by accelerometers. The lipid profile indicators analyzed were total cholesterol (TC), low-density (LDL-C) and high-density lipoproteins cholesterol (HDL-C), triglycerides (TG), non-HDL-C, TC/HDL-C and TG/HDL-c ratios. There was an inverse association between MPA time and TC values (ß = −0.560; 95%CI: −1.116; −0.004); VPA and LDL-C (ß = −0.962; 95%CI: −1.678; −0.246) and non-HDL-C (ß = −0.955; 95%CI: −1.708; −0.201); and MVPA and TC (ß = −0.436; 95%CI: −0.816; −0.055), TG (ß = −0.415; 95%CI: −0.712; −0.118), LDL-C (ß = −0.460; 95%CI: −0.823; −0.096), non-HDL-C (ß = −0.522; 95%CI: −0.908; −0.136) and TC/HDL-C (ß = −0.472; 95%CI: −0.889; −0.055). Adolescents more engaged in PA, especially in MVPA, exhibited better levels of TC, TG, LDL-C, non-HDL-C and TC/HDL-C; and AFV exerted a greater influence on LDL-c and non-HDL-c levels. HighlightsThis study is one of the first observational longitudinal studies to analyze the association between different PA intensities, measured by accelerometer, and lipid profile indicators, with a 4-year follow-up and 3 collection points in adolescents from a low-to-middle income country;Adolescents engaged in PA, especially MVPA intensity, obtained better TC, TG, LDL-c, non-HDL-C and TC/HDL-C levels;VPA was more strongly associated with LDL-C and non-HDL-C levels compared to MVPA.
