ABSTRACT Introduction: Triathlon can be considered one of the most successful endurance sports worldwide due to the wide dissemination of information, expansion of the offer of competitions, and greater popularity. Objective: To analyze Brazilian triathletes’ sociodemographic, socioeconomic, and motivational profiles. Methods: 411 triathletes participated in the study, 127 women [37.87 ± 9.34 years] and 284 men [36.02 ± 9.23 years]. Three questionnaires were sent electronically to assess sociodemographic, socioeconomic, and motivational data. In addition, descriptive analyses and statistical tests were performed to compare motivation between age, sex, and technical level groups. Results: It was found that there is a prevalence of male triathletes, amateurs, aged between 30-40 years, employed and economically favored. Amateur athletes have running as a base sport for Triathlon, and professionals start their sports career through swimming. Among the most practiced distances are the sprint Triathlon and half Ironman. Regarding motivation, women differ in the dimensions of group activity (p=0.020), emotion (p=0.002), and technical competence (p=0.007). Professional triathletes had higher scores in the dimensions of social recognition (p=0.001) and competition (p=0.001) and lower scores in the physical fitness dimension (p=0.005). Triathletes aged between 35 and 49 years had lower averages in the social recognition dimension (p=0.007), (p=0.012) and (p=0.004) and competition (p=0.028), (p=0.008) and (p=0.044) when compared to athletes aged 20 to 29 years. Conclusion: the profile of Brazilian triathletes is diverse, and differences in sex, age, and technical level impacted the motivation of the evaluated triathletes. Level of Evidence III; Diagnostic studies - Investigation of a diagnosis test; Study of non-consecutive patients, with no uniformly applied “gold standard”.

RESUMEN Introducción: El triatlón puede considerarse uno de los deportes de resistencia de mayor éxito a nivel mundial debido a la gran difusión de información, ampliación de la oferta de competiciones y mayor popularidad.

ABSTRACT BACKGROUND: The High Activity Arthroplasty Score (HAAS) is a self-administered questionnaire, developed in British English, that reliably and validly measures the levels of sports activities in patients following hip and knee arthroplasty surgery. OBJECTIVE: To cross-culturally adapt the HAAS to Brazilian Portuguese language. DESIGN AND SETTING: A cross-sectional study was conducted at a public university hospital in Brazil. METHODS: The Brazilian version of the HAAS was created through a six-step process: translation, synthesis, committee review, pretesting, back-translation, and submission to developers. The translation step was conducted by two independent bilingual translators, both native speakers of Brazilian Portuguese. The back-translation was performed by an independent translator, a native speaker of British English. To ensure the questionnaire's comprehensibility, 46 volunteers (51% men; average age 34-63) participated in the pre-testing step. RESULTS: The cross-cultural adaptation process necessitated modifications to certain terms and expressions to achieve cultural equivalence with the original HAAS. CONCLUSION: The HAAS has been translated from English into Brazilian Portuguese and culturally adapted for Brazil. The validation process for HAAS-Brazil is currently underway.

ABSTRACT BACKGROUND: The Hip Sports Activity Scale (HSAS) is a hip-specific instrument for assessing the present levels of physical activity among patients with femoroacetabular impingement (FAI) syndrome. When evaluating treatment outcomes in patients with FAI syndrome, it is necessary to use joint-specific instruments and ones that can evaluate the levels of physical activity in these patients, such as the HSAS-Brazil. OBJECTIVE: To validate the HSAS-Brazil among a group of physically active patients after arthroscopic treatment of FAI syndrome. DESIGN AND SETTING: Cross-sectional research of quantitative and qualitative types using data obtained from July 2018 to October 2019. METHODS: A total of 58 patients of both genders diagnosed with FAI syndrome and who had undergone hip arthroscopy participated in this research. To establish reliability and validity, patients first answered the Brazilian versions of the 12-Item Short-Form Health Survey (SF-12), Nonarthritic Hip Score (NAHS), and HSAS; after a 48-hour interval, they answered the HSAS-Brazil again. RESULTS: For test-retest reliability, the interclass correlation was 0.908 (P < 0.001). The HSAS-Brazil correlated to the NAHS-Brazil (r = 0.63, P < 0.001), as well as the SF-12 (Physical Health) (r = 0.42, P = 0.001). CONCLUSION: The HSAS-Brazil was validated and proved to be a reliable and valid scale to assess sports activity levels in physically active patients with FAI syndrome after arthroscopic treatment.

Abstract Objective To synthesize and critically evaluate the scientific evidence from observational studies on biosurveillance systems and adverse event reporting in organ donation and transplantation. Methods Systematic review of observational studies following the recommendations of the Methodological Guidelines (REBRATS) and Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Primary studies and case reports on biosurveillance and/or adverse events in organ donation and/or transplantation, without restriction of publication date or language were included. Six electronic databases were used in the scientific literature search: Medical Literature Analysis and Retrieval System Online (MEDLINE) (via PubMed), Excerpta Medica Database (Embase), Web of Science, LILACS, Scopus and the electronic library Scielo. A data search was also performed in the following secondary databases: Notify - World Health Organization (WHO), Pan American Health Organization (PAHO) and Google Scholar. The MINORS tool was used to assess the quality of studies. Results 551 studies were identified, and after the evaluation steps, eight of them were included in the systematic review. These were divided into results, processes and strategies for preventing adverse events. Regarding the classification of the quality of studies, two obtained a good classification. Conclusion The results indicate the occurrence of adverse events at some stage of the organ and tissue donation and transplantation process, such as: adverse drug-related reactions; neurotoxicity; longer length of hospital stay; surgical reinterventions; falls; coma; death; graft failure or loss. The fact that adverse events are possibly still underreported is noteworthy.

Resumen Objetivo Sintetizar y evaluar críticamente las evidencias científicas provenientes de estudios observacionales sobre sistemas de biovigilancia y notificación de eventos adversos en la donación y trasplante de órganos.

Abstract This systematic review and meta-analysis aimed to analyze the impact of the COVID-19 pandemic on dental trauma patient attendance. The study was registered in the PROSPERO system, using the CRD42021288398 protocol. Searching was performed in PubMed, Scopus, Web of Science, Embase, Lilacs, and OpenGrey databases, using the following keywords: “Tooth injuries,” “Dental trauma,” “Traumatic Dental injury,” and “COVID-19". We included observational studies evaluating dental trauma in the context of the COVID-19 pandemic. Quality assessment was performed using the Joanna Briggs Institute Critical Appraisal Checklist for Cross-Sectional Studies. Meta-analysis was performed in RevMan 5.4 software with Odds Ratios as a pooled measure of effect, with a 95% confidence interval, and using random-effects modeling. After applying the eligibility criteria, 32 studies were included for qualitative analysis, in which 10 were used to assess the frequency of dental trauma diagnoses in dental emergencies. Despite the decrease of visits during COVID-19, the analysis revealed no difference between the pandemic and pre-pandemic periods. Regarding the type of dental trauma, two of the studies revealed no differences for the periods before and during the pandemic. This study revealed that the COVID-19 pandemic has not impacted the frequency or type of dental trauma compared to previous periods.

Abstract Accumulated evidence has shown that the oral cavity may be an important reservoir for SARS-CoV-2. Some authors have suggested that the use of mouthrinses could reduce SARS-CoV-2 viral load in the saliva. Thus, the aim of this review was to synthesize evidence about the efficacy of mouthrinses in reducing the salivary viral load of SARS-CoV-2. 2. Nine randomized controlled trials (RCTs) have investigated the efficacy of different mouthrinses in reducing salivary SARS-CoV-2 loads. Various active ingredients have been tested in these trials: 0.5%,1% and 2% povidone-iodine, 0.2% and 0.12% chlorhexidine (CHX), 0.075% cetylpyridinium chloride (CPC), 0.075% CPC with Zinc lactate, 1% and 1.5% hydrogen peroxide (HP), 1.5% HP + 0.12% CHX and ß-cyclodextrin and citrox. The studies reported an intra-group reduction in the salivary levels of the virus, when compared with the baseline. However, the majority of these trials failed to demonstrate a significant inter-group difference between active groups and the control group relative to the decrease in salivary SARS-CoV-2 loads. Although promising, these results should be confirmed by larger trials.

Abstract Measurements of the marine carbonate system on tropical and subtropical continental margins are poorly distributed in space and time, with many uncertainties persisting regarding the role of carbon exchanges at the ocean-atmosphere interface in these areas. To calculate sea-to-air CO 2 fluxes in Marine Ecoregions along the Brazilian continental margin (4°N to 34°S), we used data from the Surface Ocean CO 2 Atlas (SOCAT v2020), collected up to 400 km from the coast, at the surface (5 m), between 1991 and 2018, with the aim of investigating the role of ecoregions as potential sinks or sources of atmospheric CO 2. The temperature and salinity of seawater presented variability in the north-south direction mainly because of the broad latitudinal range, reflecting typical patterns of tropical (T = 27.4°C ±1.49; S = 36.4 ±1.91) and subtropical waters (T = 22.8°C ±3.41; S = 35 ±2.91), in addition to the greater or lesser influence of river inputs in each ecoregion. The pCO 2 values in the surface waters varied from 121.81 (Amazon) to 478.92 μatm (Eastern), differing significantly between ecoregions and showing an expected decadal increasing trend, both in the atmosphere and in the seawater. The calculated values of CO 2 fluxes showed non-homogeneous spatio-temporal variations, from -24.37 mmol m-2 d-1 (Rio Grande) to 9.87 mmol m- 2 d-1 (Southeastern). Throughout the analyzed time series, we observed that the Northeast, Amazon and Eastern ecoregions acted predominantly as sources of CO 2 and the Southeastern ecoregions and, mainly, Rio Grande, acted predominantly as sinks of atmospheric CO 2.

BACKGROUND Chikungunya is a mosquito-borne virus that has been causing large outbreaks in the Americas since 2014. In Brazil, Asian-Caribbean (AC) and East-Central-South-African (ECSA) genotypes have been detected and lead to large outbreaks in several Brazilian states. In Rio Grande do Sul (RS), the southernmost state of Brazil, the first cases were reported in 2016. OBJECTIVES AND METHODS We employed genome sequencing and epidemiological investigation to characterise the Chikungunya fever (CHIKF) burden in RS between 2017-2021. FINDINGS We detected an increasing CHIKF burden linked to travel associated introductions and communitary transmission of distinct lineages of the ECSA genotype during this period. MAIN CONCLUSIONS Until 2020, CHIKV introductions were most travel associated and transmission was limited. Then, in 2021, the largest outbreak occurred in the state associated with the introduction of a new ECSA lineage. CHIKV outbreaks are likely to occur in the near future due to abundant competent vectors and a susceptible population, exposing more than 11 million inhabitants to an increasing infection risk.

Abstract The aim of this study was to determine the presence of deoxyribonucleic acid (DNA) from Toxoplasma gondii, Sarcocystis spp. and Neospora caninum, in tissues of wild boars slaughtered in southern Brazil. A total of 156 samples were collected from different organs of 25 wild boars, and DNA from at least one of the protozoa investigated was detected in 79 samples. To differentiate between infectious agents, restriction fragment length polymorphism was performed using the restriction enzymes DdeI and HpaII. For N. caninum, conventional PCR was performed with specific primers. The DNA of at least one of the studied pathogens was detected in each animal: 26.58% for T. gondii, 68.36% for Sarcocystis spp. and 5.06% for N. caninum. Coinfection between T. gondii and Sarcocystis spp. occurred in 14 animals, between T. gondii and N. caninum in only one male animal, between Sarcocystis spp. and N. caninum in a female, while co-infection with the three agents was equally observed in only one male animal. Considering the high frequency of detection and its zoonotic risk, especially T. gondii, it appears that wild boars can be potential sources of transmission of infectious agents and the adoption of monitoring measures in these populations should be prioritized.

Resumo O objetivo deste estudo foi determinar a presença de ácido desoxirribonucléico (DNA) de Toxoplasma gondii, Sarcocystis spp. e Neospora caninum, em tecidos de javalis abatidos no sul do Brasil. Foram coletadas 156 amostras de diferentes órgãos de 25 javalis, sendo detectado o DNA de pelo menos um dos protozoários pesquisados em 79 amostras. Para diferenciar entre os agentes infecciosos, o polimorfismo do comprimento do fragmento de restrição, foi realizado usando-se as enzimas de restrição DdeI e HpaII. Para N. caninum, a PCR convencional foi realizada com "primers" específicos. O DNA de pelo menos um dos patógenos estudados foi detectado em cada animal: 26,58% para T. gondii, 68,36% para Sarcocystis spp. e 5,06% para N. caninum. Coinfecção entre T. gondii e Sarcocystis spp. ocorreu em 14 animais; entre T. gondii e N. caninum em apenas um animal macho; entre Sarcocystis spp. e N. caninum em uma fêmea, enquanto a coinfecção com os três agentes foi observada igualmente em apenas um animal macho. Considerando-se a alta frequência de detecção e seu risco zoonótico, especialmente T. gondii, constata-se que os javalis podem ser potenciais fontes de transmissão de agentes infecciosos, e a adoção de medidas de monitoramento nessas populações devem ser priorizadas.

SOURCE OR SINK? A REVIEW OF THE CO2 FLUXES AT THE BRAZILIAN CONTINENTAL SHELF. Studies of global carbon balance estimates are still incipient in the oceans of the Southern Hemisphere, mainly in coastal areas and continental shelf. Even in Brazil, despite its continental proportion coastline, there is still a great inconsistency in studies on the marine carbonate system and CO2 fluxes at the air-sea interface. This article presents a review of studies on CO2 fluxes on the coast of Brazil, published between the years 2000 and 2022, aiming to map the distribution of CO2 fluxes on the Brazilian continental shelf, to understand its role as a source or sink of CO2. In general, large-scale studies show that the Brazilian shelf exhibits a latitudinal variation of air-sea CO2 fluxes, behaving mainly as a source in the north, where there is no influence of the Amazon River plume, and as a sink in the south portion. We also identified there is a strong influence on the occurrence of mesoscale and synoptic oceanographic and meteorological events, and the presence of different ecosystems, which can change the behavior of CO2 fluxes locally. However, there are still many data gaps along the continental shelf, as well as in different seasons for the entire coast.

Abstract Faced with the recent crises of water capture and distribution, managing water resources is a practice that has been gaining prominence in discussions and debates about environmental issues. Thus, this article aims to analyze, in a spatio-temporal way, the Changes in Land Use and Occupation (LULC) and Surface Temperature (LST) in the water catchment sub-basin of Ribeirão Santa Isabel, located in the municipality of Paracatu, Minas Gerais (MG), between the years 1990 and 2020. The choice of the area is justified by the conflicts of use that encompass the sub-basin and by the fact that this is the only source of capture in the municipality, which has already carried out the alteration of the water resource responsible for the capture of water due to the intensity of agricultural practices in the region in the previous area. Through geoprocessing and Remote Sensing (RS) techniques, images from the Landsat-5 and Landsat-8 satellites were used to perform the LST calculations. Regarding usage and occupancy data, the images provided by the Mapbiomas platform were used. It was verified, through the increase in the percentage of the water class and vegetation and the decrease in the agricultural class, that the practices implemented in the study area, in order to conserve the remnants of the biome and maintain a good water availability to the municipality, are having an effect. It was also possible to conclude that LST is affected by LULC, and that the greatest variations occur in non-vegetated areas.

Considering the current environmental problems associated with the growing world demand for energy arising from development and population growth, the need to diversify energy matrices, such as the implementation of solar energy, is highlighted. Thus, it is important to discuss this topic in the school environment, because when they are introduced from childhood to high school, the probability of this orientation being effective is much greater. In this context, educational games have attracted attention as a teaching tool, combining a fun atmosphere with the improvement of learning. This work aimed the production and application of a game in board format representing a dye-sensitized solar cell (CSSC) as a didactic resource in approaching the content of energy conversion. The game allowed an easy visualization of how the energy conversion process is performed by a CSSC. It was presented during the scientific dissemination event “Café com Ciência”, promoted by the Federal University of São João del-Rei, with good results both in gameplay aspects and in helping to understand the theme. The feedback obtained indicates that the game can be a useful tool for students and educators, reaching all its didactic potential and facilitating learning in the face of complex concepts.

ABSTRACT The diagnosis of congenital toxoplasmosis presents limitations and therefore new options are necessary. The analysis of amniotic fluid by real-time PCR has already proved effective for confirmation of fetal infection. However, its performance in other biological samples is not clear yet. The aim of this study is to better understand the role of real-time PCR in the blood of the mother and newborn as well as in the amniotic fluid and placenta in the diagnosis of congenital toxoplasmosis. This is a descriptive cohort study of pregnant women with toxoplasmosis followed up in Rio de Janeiro, Brazil. Real-time PCR was performed in samples of maternal blood, amniotic fluid, placenta, and blood of newborns. In addition, histopathological examination of placentas was performed, and data collected from babies were collected. 116 pregnant women were followed up and 298 samples were analyzed. One (0.9%) pregnant woman presented positive PCR in the blood, 3 (3.5%) in the amniotic fluid, 1 (2.3%) in the placenta and no newborn had positive PCR in the blood. Histopathological study was suggestive of toxoplasmosis infection in 24 (49%) placentas. Six (5.2%) newborns were diagnosed with congenital toxoplasmosis, and only cases with positive PCR in the amniotic fluid had correlation of the PCR result with the diagnosis of congenital infection. Both maternal and blood samples of new-borns and placenta did not prove to be promising in the diagnosis of congenital toxoplasmosis. Further studies are needed to evaluate the real role of molecular diagnosis in other biological materials rather than the amniotic fluid.

■ ABSTRACT Introduction: Since the beginning of the COVID-19 pandemic, medical specialties have adapted their routine, postponing non-essential procedures, which resulted in a reduction in the number of surgical visits, directly impacting teaching hospitals. This work aims to evaluate the impact of the COVID-19 pandemic on the activities of the surgical specialties at the University Hospital Professor Edgard Santos (C-HUPES), located in Salvador-BA. Method: Observational, cross-sectional, retrospective study, which compares the year 2020 to the year 2019, in which the impacts of the pandemic on the surgical activities (especially plastic surgery) of the hospital are analyzed through the total number of procedures, hospitalizations, and outpatient consultations of surgical specialties. Results: A reduction of 45,45% of the total number of surgical procedures was observed, with 220 surgeries in 2019 and 120 surgeries in 2020. Reduction of 37.29% in hospitalizations, totaling 236 in 2019 and 148 in 2020. There was a decrease of 40.90% in outpatient consultations, with 2941 consultations performed in 2019 and 1738 consultations in 2020. It is noticed that the worst periods of reduction in 2020 were from March to June, in addition to a new drop in November and December. Conclusion: The pandemic impacted the activities of the surgical specialties at C-HUPES due to the total reduction in the number of surgeries, consultations, and hospitalizations in 2020, impairing the care of plastic surgery patients in absolute numbers. It is inferred that the COVID-19 pandemic hampered the training of plastic surgery residents.

■ RESUMO Introdução: Desde o início da pandemia de COVID-19, as especialidades médicas adaptaram sua rotina, postergando procedimentos não essenciais, o que resultou em redução no número de atendimentos cirúrgicos, impactando diretamente nos hospitais de ensino. O objetivo desse trabalho é avaliar o impacto da pandemia de COVID-19 nas atividades das especialidades cirúrgicas do Hospital Universitário Professor Edgard Santos (C-HUPES), localizado em Salvador-BA. Método: Estudo observacional, transversal, retrospectivo, que compara o ano de 2020 ao ano de 2019, em que são analisados os impactos da pandemia nas atividades cirúrgicas (especialmente na cirurgia plástica) do hospital, através do número total de procedimentos, internações e de consultas ambulatoriais das especialidades cirúrgicas. Resultados: Redução de 45,45% no número total de procedimentos cirúrgicos foi observada, havendo um total de 220 cirurgias em 2019 e 120 cirurgias em 2020. Redução de 37,29% no número total de internamentos, total de 236 em 2019 e 148 em 2020. Observou-se diminuição de 40,90% nas consultas ambulatoriais, realizadas 2941 consultas em 2019 e 1738 consultas em 2020. Percebe-se que os piores períodos de redução em 2020 foram de março a junho, além de nova queda em novembro e dezembro. Conclusão: A pandemia impactou as atividades das especialidades cirúrgicas do C-HUPES, devido à redução total da quantidade de cirurgias, consultas e internamentos em 2020, prejudicando a assistência aos pacientes da cirurgia plástica em números absolutos. Infere-se que a pandemia de COVID-19 prejudicou a formação dos residentes de cirurgia plástica.
