Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

Abstract Abstract: Trichiurus lepturus (Actinopterygii, Perciformes) is a commercially and economically important fish. A total of 60 specimens of this cutlassfish were collected of the coast the municipalities of Niterói and Cabo Frio, state of Rio de Janeiro, Brazil. The fish were measured, necropsied, filleted and had their organs investigated for digenetic trematodes. Taxonomic identification was based on morphological and morphometric characters. The specimens of T. lepturus were parasitized with adult specimens of Lecithochirium monticellii. Parasite indices of prevalence, intensity, mean intensity, abundance, mean abundance, range of infection, and site of infection of parasitic species were evaluated. Notes on the taxonomy of the parasite were also included. This is the first report of L. monticellii parasitizing T. lepturus in Brazil.

The intraerythrocytic parasites Babesia caballi and Theileria equi are the etiological agents of equine piroplasmosis. This disease affects different horse breeds and it has a significant economic impact on the horse industry. The objective of the present study was to determine the presence of B. caballi and T. equi by blood smear and their association with the hematological parameters. Fifty-eight blood samples were taken from clinically healthy horses, which were diagnosed with B. caballi and T. equi infections by blood smear; in addition, the hematological examination of the red and white series was carried out. The mean value of all the hematological parameters evaluated was among the physiological values described for the horse species. From the total samples analyzed, intraerythrocytic formations compatible with B. caballi and T. equi were observed in 3/58 (5.2 %) and 8/58 (13.8 %) animals, respectively. Of these animals, 6/11 (10.3 %) had hematocrit values lower than those physiological. The association between positive animals and possible risk factors (age, sex, presence of ticks and contact with bovines) was evaluated. The statistical analysis showed significant differences when evaluating the relationship between hematocrit values and positive samples to T. equi

BALB/c mice were inoculated with 5-500 Toxocara canis infective eggs, and bled at 15-120 days post infection (dpi) to evaluate the dynamics of IgG antibody response and larvae distribution. Positive results were observed in all occasions for every inoculum, and a direct proportional relationship between antibody detection and the parasitic load was observed. In samples collected at 60 dpi, detection of IgG was more intense, especially with the 50 and 500 egg doses; also, a correlation between antibody level and egg count was observed with these two inocula. At 120 dpi, a decrease in antibody titer was observed for all groups; and at the end of the experiment, larvae were recovered from carcass, liver and brain. In the liver, larvae were only found in mice inoculated with 500 T. canis eggs. In carcasses, these were recovered in all groups, and the group inoculated with 50 eggs showed the highest percentage of larvae in the brain.

ABSTRACT Background Reducing rearfoot eversion is a commonly desired effect in clinical practice to prevent or treat musculoskeletal dysfunction. Interventions that pull the lower limb into external rotation may reduce rearfoot eversion. Objective This study investigated whether the use of external rotation elastic bands, of different levels of stiffness, will decrease rearfoot eversion during walking. We hypothesized that the use of elastic bands would decrease rearfoot eversion and that the greater the band stiffness, the greater the eversion reduction. Method Seventeen healthy participants underwent three-dimensional kinematic analysis of the rearfoot and shank. The participants walked on a treadmill with and without high- and low-stiffness bands. Frontal-plane kinematics of the rearfoot-shank joint complex was obtained during the stance phase of walking. Repeated-measures ANOVAs were used to compare discrete variables that described rearfoot eversion-inversion: mean eversion-inversion; eversion peak; and eversion-inversion range of motion. Results The low-stiffness and high-stiffness bands significantly decreased eversion and increased mean eversion-inversion (p≤0.037) and eversion peak (p≤0.006) compared with the control condition. Both bands also decreased eversion-inversion range of motion (p≤0.047) compared with control by reducing eversion. The high-stiffness band condition was not significantly different from the low-stiffness band condition for any variables (p≥0.479). Conclusion The results indicated that the external rotation bands decreased rearfoot eversion during walking. This constitutes preliminary experimental evidence suggesting that increasing external rotation moments at the lower limb may reduce rearfoot eversion, which needs further testing.

Resumo O objetivo do presente trabalho foi determinar a soropositividade paraLeishmania spp. e Trypanosoma cruzi em cães do Estado da Paraíba, Nordeste do Brasil, bem como identificar fatores de risco. Foram utilizados 1.043 cães e, para o diagnóstico sorológico de doença de Chagas (DC) e leishmaniose visceral canina (LVC), foi utilizada a reação de imunofluorescência indireta (RIFI). Animais positivos para ambas as doenças (pela RIFI) foram submetidos ao ELISA. Dos 1.043 cães investigados, 81 foram soropositivos para Leishmania spp., resultando em prevalência de 7,8% (IC 95% = 6,1-9,4%) e, para T. cruzi, 83 (7,9%; IC 95% = 6,3-9,6%) animais foram soropositivos. Quarenta e nove animais (4,6%; IC 95% = 3,6-6,2%) apresentaram sororeatividade mista. Criação semidomiciliar (OR = 2,044), criação solta (OR = 4,151), ambiente de terra (OR = 3,425) e ambiente de terra/cimento (OR = 3,065) foram apontados como fatores de risco para LVC, e criação semidomiciliar (OR = 2,353), criação solta (OR = 3,454) e contato com bovinos (OR = 2,015) para DC. Conclui-se que LVC e DC estão presentes em cães do Estado da Paraíba, o que sugere revisão e intensificação das medidas de controle através do constante monitoramento da população canina.

Abstract The aim of this survey was to determine the seropositivity and risk factors forLeishmania spp. and Trypanosoma cruzi in dogs in the State of Paraíba, Northeastern Brazil. A total of 1,043 dogs were tested, and the serological diagnoses of Chagas disease (CD) and canine visceral leishmaniasis (CVL) was performed by the indirect fluorescent antibody test (IFAT). Animals that tested seropositive for both diseases (by IFAT) were further subjected to ELISA. Of the 1,043 dogs 81 (7.8%; 95% CI = 6.1-9.4%) tested seropositive for Leishmania spp., while 83 were seropositive for T. cruzi (7.9%; 95% CI = 6.3-9.6%). Simultaneous serological reactions were detected in 49 animals (4.6%; 95% CI= 3.6-6.2%). Semi-domiciled housing (OR = 2.044), free housing (OR = 4.151), and soil (OR = 3.425) and soil/cement (OR = 3.065) environmental conditions were identified as risk factors for CVL seropositivity. The risk factors identified for CD seropositivity were semi-domiciled (OR = 2.353) or free housing (OR = 3.454), and contact with bovine (OR = 2.015). This study revealed the presence of dogs in the Paraíba State seropositive for CVL and CD, suggesting the need for revisiting and intensification of disease control measures through constant monitoring of the canine population.

ABSTRACTObjective:To establish the injury profile of soccer players from a first division Brazilian soccer team. In addition, we investigated the association between the characteristics of the injuries and the player's age and position.Method: Forty-eight players from a Brazilian first division soccer team were followed during one season. Descriptive statistics were used to characterize the injury profile. Spearman's tests were used to verify the association between the number and severity of injuries and the player's age. Chi-square test was used to verify the association between type of injury and player's position. Fisher's exact test was used to verify the association between the severity of injuries and player's position.Results: The incidence of injuries was 42.84/1000 hours in matches and 2.40/1000 hours in training. The injury severity was 19.5±34.4 days off competition or training. Lower limb was the most common location of injury and most injuries were muscular/tendinous, overuse, non-recurrent, and non-contact injuries. Player's age correlated with the amount and severity of muscle and tendon injuries. Defenders had more minimal injuries (1-3 days lost), while forwards had more moderate (8-28 days lost) and severe injuries (>28 days lost). Furthermore, wingbacks had more muscle and tendon injuries, while midfielders had more joint and ligament injuries.Conclusion: The injury profile of the Brazilian players investigated in this study reflected regional differences in soccer practices. Results confirm the influence of the player's age and position on the soccer injuries profile.

Introduction: Patellofemoral pain syndrome (PFPS) is characterized by anterior knee pain, which may limit the performance of functional activities. The influence of hip joint motion on the development of this syndrome has already been documented in the literature. In this regard, studies have investigated the effectiveness of hip muscle strengthening in patients with PFPS. Objectives: The aims of this systematic review were (1) to summarize the literature related to the effects of hip muscle strengthening on pain intensity, muscle strength, and function in individuals with PFPS and (2) to evaluate the methodological quality of the selected studies. Method: A search for randomized controlled clinical trials was conducted using the following databases: Google Scholar, MEDLINE, PEDro, LILACS, and SciELO. The selected studies had to distinguish the effects of hip muscle strengthening in a group of patients with PFPS, as compared to non-intervention or other kinds of intervention, and had to investigate the following outcomes: pain, muscle strength, and function. The methodological quality of the selected studies was analyzed by means of the PEDro scale. Results: Seven studies were selected. These studies demonstrated that hip muscle strengthening was effective in reducing pain. However, the studies disagreed regarding the treatments' ability to improve muscle strength. Improvement in functional capabilities after hip muscle strengthening was found in five studies. Conclusion: Hip muscle strengthening is effective in reducing the intensity of pain and improving functional capabilities in patients with PFPS, despite the lack of evidence for its ability to increase muscle strength.

Background: Isokinetic dynamometry allows the measurement of several variables related to muscular performance, many of which are seldom used, while others are redundantly applied to the characterization of muscle function. Objectives: The present study aimed to establish the particular features of muscle function that are captured by the variables currently included in isokinetic assessment and to determine which variables best represent these features in order to achieve a more objective interpretation of muscular performance. Method: This study included 235 male athletes. They performed isokinetic tests of concentric knee flexion and extension of the dominant leg at a velocity of 60º/s. An exploratory factor analysis was performed. Results: The findings demonstrated that isokinetic variables can characterize more than muscle torque production and pointed to the presence of 5 factors that enabled the characterization of muscular performance according to 5 different domains or constructs. Conclusions: The constructs can be described by torque generation capacity; variation of the torque generation capacity along repetitions; movement deceleration capacity; mechanical/physiological factors of torque generation; and acceleration capacity (torque development). Fewer than eight out of sixteen variables are enough to characterize these five constructs. Our results suggest that these variables and these 5 domains may lead to a more systematic and optimized interpretation of isokinetic assessments.

O objetivo do presente trabalho foi determinar a frequência de anticorpos anti-Toxoplasma gondii e anti-Neospora caninum, bem como identificar fatores de risco em cães do município de Natal, Estado do Rio Grande do Norte, Nordeste do Brasil. Para tanto, foram colhidas amostras de sangue de 476 cães atendidos em clínicas veterinárias no período de março de 2011 e maio de 2012. Para o diagnóstico sorológico das infecções, foi utilizada a reação de imunofluorescência indireta (RIFI), adotando-se como pontos de corte as diluições 1:64 (T. gondii) e 1:50 (N. caninum). Das 476 amostras, 55 (11,5%; IC 95%=8,8%-14,8%) foram soropositivas para T. gondii, e 31 (6,5%; IC 95%=4,5%-9,1%) para N. caninum. As variáveis idade > 48meses (OR=4,68) e acesso à rua (OR=4,91) foram identificadas como fatores de risco para T. gondii, enquanto que para N. caninum, os fatores de risco foram limpeza semanal/quinzenal/mensal do ambiente onde o animal vive (OR=2,77) e presença de ratos (OR=2,34). Conclui-se que as infecções por T. gondii e N. caninum, detectadas por sorologia, estão presentes em cães atendidos em clínicas veterinárias do município de Natal, bem como se recomenda a correção dos fatores de risco identificados.

The aim of this survey was to determine the frequency of anti-Toxoplasma gondii and anti-Neosporacaninum antibodies, as well as to identify risk factors in dogs from the county of Natal, Rio Grande do Norte state, Northeastern Brazil. Blood samples were collected from 476 dogs attended at veterinary clinics from March 2011 to May 2012. For the serological diagnosis of the infections the indirect fluorescent antibody test (IFAT) adopting the dilutions 1:64 (T. gondii) and 1:50 (N. caninum) as cut-off points, was used. Of the 476 samples 55 (11.5%, 95% CI=8.8%-14.8%) were seropositive to T. gondii, and 31 (6.5%, 95% CI=4.5%-9.1%) to N. caninum. The variables age >48 months (OR=4.68) and access to street (OR=4.91) were identified as risk factors for T. gondii, while for N. caninum, risk factors were weekly/fortnightly/monthly cleaning of the environment where the animal stay (OR=2.77) and presence of rodents (OR=2.34). It is concluded that infectionsdue to T. gondii and N. caninum detected by serology are present in dogs attended at veterinary clinics in the county of Natal, as well as it is recommended the correction of the risk factors identified.

CONTEXTUALIZAÇÃO: Rigidez passiva adequada do quadril pode impedir movimentos excessivos dos membros inferiores no plano transverso durante a realização de atividades funcionais. O fortalecimento muscular dos rotadores laterais do quadril poderia ser utilizado na tentativa de aumentar a rigidez dessa articulação. No entanto, a relação entre rigidez passiva e força dos músculos do quadril não está documentada na literatura. OBJETIVO: Investigar a associação entre rigidez passiva do quadril durante o movimento de rotação medial e torque concêntrico dos rotadores laterais dessa articulação em indivíduos saudáveis. MÉTODO: Foram avaliados 26 indivíduos com média de idade de 24,42±2,77 anos. Para quantificação da rigidez passiva do quadril, o torque passivo de resistência durante a rotação medial dessa articulação foi mensurado por um dinamômetro isocinético. A rigidez foi determinada como a inclinação média da curva de torque passivo obtida nos primeiros 20° do movimento. Eletromiografia foi utilizada para verificar o repouso dos músculos do quadril durante esse procedimento. O dinamômetro isocinético também foi utilizado para avaliação do pico de torque e trabalho máximo dos rotadores laterais do quadril em uma amplitude de 55° de rotação. RESULTADOS: Regressões lineares demonstraram coeficientes de correlação r=0,70 (R²=0,50/p<0,001) e r=0,77 (R²=0,59/p<0,001) entre rigidez do quadril e as medidas de pico de torque e trabalho muscular dos rotadores laterais, respectivamente. CONCLUSÕES: Existe associação de moderada a boa entre rigidez passiva do quadril e torque concêntrico dos rotadores laterais dessa articulação. A associação demonstrada sugere que o fortalecimento dos rotadores laterais pode ser eficaz em aumentar a rigidez do quadril.

BACKGROUND: Adequate passive stiffness of the hip joint can prevent the occurrence of excessive transverse plane lower limb movement during functional activities. Strength training of the hip lateral rotator muscles can be used to increase the stiffness of this joint. However, the relationship between hip joint passive stiffness and muscle strength remains undocumented in the literature. OBJECTIVE: To investigate the association between hip passive stiffness measured during medial rotation and hip lateral rotator concentric torque in healthy young adults. METHOD: Twenty-six individuals with mean age of 24.42±2.77 years participated in the present study. To quantify hip stiffness, the passive resistance torque during medial rotation was measured using an isokinetic dynamometer. Stiffness was determined by the mean slope of the passive torque curve obtained in the first 20° of motion. Electromyography was used to ensure inactivity of the hip muscles during this procedure. The isokinetic dynamometer was also used for assessment of hip lateral rotator peak torque and work in a range of motion of 55° of rotation. RESULTS: Linear regressions demonstrated correlation coefficients of r=0.70 (R²=0.50/p<0.001) and r=0.77 (R²=0.59/p<0.001) between hip passive stiffness and the measures of lateral rotator peak torque and work, respectively. Conclusions: There is a moderate to good association between hip passive stiffness and lateral rotator concentric torque. This association suggests that lateral rotator strength training can increase hip stiffness.

CONTEXTUALIZAÇÃO: O teste da ponte com extensão unilateral do joelho avalia a estabilidade de tronco e pelve. A avaliação dessa estabilidade pode contribuir para o entendimento da ocorrência de lesões musculoesqueléticas. OBJETIVOS: Investigar a confiabilidade intra e interexaminador de uma análise qualitativa e a confiabilidade intrateste de uma análise quantitativa do alinhamento pélvico no plano transverso durante o teste da ponte com extensão unilateral do joelho. MÉTODO: Foram avaliados 30 participantes (24,73±4,24 anos). A análise qualitativa foi realizada pelo julgamento do alinhamento pélvico no plano transverso por dois examinadores, e sua confiabilidade determinada pelo Coeficiente Kappa Ponderado (k w). A análise quantitativa foi realizada pela medida do maior ângulo de desalinhamento pélvico no plano transverso e a confiabilidade determinada pelo Coeficiente de Correlação Intraclasse (CCI); pela análise da mudança na média dos dados, utilizando-se o intervalo de confiança de 95% da média da diferença (95%IC<img src="/img/revistas/rbfis/v16n4/a07tex01.jpg" align=absmiddle> ) e método de Bland-Altman; pelo dimensionamento da variabilidade entre medidas, considerando-se o erro-padrão da medida combinado (EPM) e coeficiente de variação do erro típico (CV ET). Além disso, verificou-se a mudança mínima detectável (MMD95). RESULTADOS: A confiabilidade intraexaminador variou de razoável a moderada (k w=0,32-0,58) e a confiabilidade interexaminador foi substancial (k w=0,80). A confiabilidade intrateste foi excelente (CCI=0,82) e apresentou o IC95% <img src="/img/revistas/rbfis/v16n4/a07tex01.jpg" align=absmiddle>de -0,51º a 1,99º, EPM de 2,38º e o CV ET de 28,75%. O MMD95 foi de 6,59º. CONCLUSÕES: O índice de confiabilidade interexaminador foi superior ao intraexaminador, a confiabilidade intrateste foi excelente e não apresentou erro sistemático e aleatório.

BACKGROUND: The bridge test with unilateral knee extension evaluates the stability of the trunk and pelvis. The evaluation of this stability can contribute to the understanding of the occurrence of musculoskeletal injuries. OBJECTIVES: To investigate the intra- and inter-rater reliability of a qualitative analysis and intra-test reliability of a quantitative analysis of transverse plane pelvic alignment during the bridge test with unilateral knee extension. METHOD: Thirty participants (24.73±4.24 years old) were tested. The qualitative analysis was conducted by asking two raters to judge the transverse plane pelvic alignment and its reliability was assessed with the weighted kappa coefficient (k w). The quantitative analysis was conducted by measuring the greatest pelvic tilt angle in transverse plane and its reliability was assessed by use of the intraclass correlation coefficient (ICC); the mean change, which was evaluated using 95% confidence interval of the mean difference (95%CI <img src="/img/revistas/rbfis/v16n4/a07tex01.jpg" align=absmiddle>) and Bland-Altman plot; and the quantification of measurement variability, which was assessed using standard error of measurement (SEM) and the coefficient of variation of the typical error (CV TE). In addition, the minimal detectable change (MDC95) was determined. RESULTS: The intra-rater reliability ranged from fair to moderate (k w=0.32 to 0.58) and the inter-rater reliability was substantial (k w=0.80). The intra-test reliability was excellent (ICC=0.82), the 95% CI <img src="/img/revistas/rbfis/v16n4/a07tex01.jpg" align=absmiddle>ranged from -0.51º to 1.99º, the SEM was 2.38º and the CV TE was 28.75%. The MDC95 was 6.59º. CONCLUSIONS: The inter-rater reliability was greater than the intra-rater reliability; the intra-test reliability was excellent and showed no systematic or random error.

OBJETIVO: Investigar o perfil do fisioterapeuta com atuação na área esportiva nas modalidades de futebol e voleibol no Brasil no que tange à sua formação, atuação e grau de autonomia dentro da equipe interdisciplinar. MÉTODOS: Foram analisados questionários estruturados para levantamento de dados sociodemográficos, dados relativos ao ambiente de trabalho e à prática clínica e os seus domínios, referentes a 49 fisioterapeutas de clubes e seleções de futebol e voleibol. RESULTADOS: Do total de entrevistados, apenas cinco fisioterapeutas eram do sexo feminino, e a idade média do grupo era de 32,2 anos. A maioria dos fisioterapeutas brasileiros que atuam no esporte possuem especialização em diversas áreas (78,2%), foram contratados por indicação (78,2%), trabalham mais de 8 horas/dia ou em regime de dedicação exclusiva (80,0%) e recebem de sete a dez ou mais salários mínimos (58,2%). Além disso, observou-se uma grande participação do fisioterapeuta nos domínios do atendimento emergencial (87,3%), prevenção (92,7%), reabilitação funcional (98,2%) e retorno após lesão (100%). O fisioterapeuta com atuação no esporte relata haver uma boa relação interdisciplinar, sobretudo com o preparador físico na reabilitação funcional (70,9%), com o médico do clube na decisão do retorno do atleta após reabilitação (74,5%) e no veto ou liberação do atleta para jogos/treinos (63,6%). Entretanto, muitos reclamaram de ameaças à sua autonomia, principalmente pelo profissional médico. CONCLUSÃO: Ainda existe a necessidade de investir na formação específica do profissional fisioterapeuta esportivo, visando a uma melhor especialização na área esportiva e consolidando conceitos importantes da área por meio de um melhor entendimento de referenciais teóricos e de atuação clínica.

OBJECTIVE: To analyze the profile of Brazilian physical therapists working with soccer and volleyball professional teams, by verifying their level of education (graduate or undergraduate), as well as their role and insertion within the interdisciplinary team. METHODS: Structured questionnaires were administered to forty-nine physical therapists working at soccer, volleyball clubs and Brazilian national teams. These questionnaires provided data on social demographic, characteristics of the work environment and organization of clinical practice and its domains. RESULTS: From the 49 participants in this study only five were female. Mean age of all participants was 32.2 years. The majority of the sports physical therapists had specialization degrees in different areas (78.2%), were hired through referral (78.2%), worked more than 8 hours a day or were exclusively dedicated to their clubs (80.0%) and earned seven to ten Brazilian minimal wages (58.2%). They reported to have participation in the domains of emergency care (87.3%), prevention (92.7%), functional rehabilitation (98.2%) and return to competition (100%). They had interdisciplinary relationships with physical educators during functional rehabilitation programs (70.9%) and with physicians in the decision process of return to activity after rehabilitation (74.5%) and on the veto of an athlete to take part in practices or matches (63.6%). Therapists also complained of threats to their professional autonomy, specially directed by the team's physician. CONCLUSION: There is still a need to invest in continuing education of sports physical therapists with the objective to improve their educational level and to strengthen their professional autonomy.
