ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract Background: Cardiorespiratory (aerobic) fitness is strongly and directly related to major health outcomes, including all-cause mortality. Maximum oxygen uptake (VO2max), directly measured by maximal cardiopulmonary exercise test (CPET), represents the subject’s aerobic fitness. However, as CPET is not always available, aerobic fitness estimation tools are necessary. Objectives: a) to propose the CLINIMEX Aerobic Fitness Questionnaire (C-AFQ); b) to validate C-AFQ against measured VO2max; and c) to analyze the influence of some potentially relevant variables on the error of estimate. Methods: We prospectively studied 1,000 healthy and unhealthy subjects (68.6% men) aged from 14 to 96 years that underwent a CPET. The two-step C-AFQ describes physical activities with corresponding values in metabolic equivalents (METs) - ranging from 0.9 to 21 METs. Results: Application of C-AFQ took less than two minutes. Linear regression analysis indicated a very strong association between estimated (C-AFQ) and measured (CPET) maximal METs - r2 = 0.83 (Sy.x = 1.63; p < .001) - with median difference of only 0.2 METs between both values and interquartile range (percentiles 25 and 75) of 2 METs. The difference between estimated and measured METs was not influenced by age, sex, body mass index, clinical condition, ß-blocker use or sitting-rising test scores. Conclusion: C-AFQ is a simple and valid tool for estimating aerobic fitness when CPET is unavailable and it is also useful in planning individual ramp protocols. However, individual error of estimate is quite high, so C-AFQ should not be considered a perfect substitute for CPET’s measured VO2max.

ResumoFundamento:A condição aeróbica, avaliada pela medida do VO2máx no teste cardiopulmonar de exercício máximo (TCPE) ou estimada por equações no teste de exercício, é preditora de mortalidade. Porém, o erro obtido pela estimativa em um dado indivíduo pode ser alto, afetando decisões clínicas.Objetivo:Determinar o erro de estimativa do VO2máx em cicloergometria em população atendida nos serviços de ergometria e propor equações específicas por sexo para minimizar o erro na estimativa do VO2máx.Métodos:Foram avaliados 1715 adultos (18 a 91 anos) (68% homens) submetidos a TCPE máximo em cicloergômetro de membros inferiores (CMI) com protocolo de rampa. Calculou-se o erro percentual (E%) entre o VO2máx medido e o estimado pela equação ACSM modificada (Lang e col. MSSE, 1992). A seguir, foram desenvolvidas equações de estimativa: 1) para toda a amostra testada (C-GERAL) e 2) separadamente por sexo (C-HOMENS e C-MULHERES).Resultados:O VO2máx medido foi maior em homens do que em mulheres - 29,4 ± 10,5 e 24,2 ± 9,2 mL.(kg.min)-1 (p < 0,01) -. As equações de estimativa do VO2máx foram mL.(kg.min)-1: C-GERAL = [carga final (W)/peso (kg)] x 10,483 + 7; C‑HOMENS = [carga final (W)/peso (kg)] x 10,791 + 7; e C-MULHERES = [carga final (W)/peso (kg)] x 9,820 + 7. Os E% em homens foram -3,4 ± 13,4% (ACSM modificada), 1,2 ± 13,2% (C-GERAL) e -0,9 ± 13,4% (C-HOMENS) (p < 0,01). Em mulheres, obtivemos: -14,7 ± 17,4% (ACSM modificada), -6,3 ± 16,5% (C-GERAL) e -1,7 ± 16,2% (C-MULHERES) (p < 0,01).Conclusão:O erro de estimativa do VO2máx através de equações específicas por sexo foi reduzido, porém não eliminado, nos testes de exercício em CMI.
AbstractBackground:Aerobic fitness, assessed by measuring VO2max in maximum cardiopulmonary exercise testing (CPX) or by estimating VO2max through the use of equations in exercise testing, is a predictor of mortality. However, the error resulting from this estimate in a given individual can be high, affecting clinical decisions.Objective:To determine the error of estimate of VO2max in cycle ergometry in a population attending clinical exercise testing laboratories, and to propose sex-specific equations to minimize that error.Methods:This study assessed 1715 adults (18 to 91 years, 68% men) undertaking maximum CPX in a lower limbs cycle ergometer (LLCE) with ramp protocol. The percentage error (E%) between measured VO2max and that estimated from the modified ACSM equation (Lang et al. MSSE, 1992) was calculated. Then, estimation equations were developed: 1) for all the population tested (C-GENERAL); and 2) separately by sex (C-MEN and C-WOMEN).Results:Measured VO2max was higher in men than in WOMEN: -29.4 ± 10.5 and 24.2 ± 9.2 mL.(kg.min)-1 (p < 0.01). The equations for estimating VO2max [in mL.(kg.min)-1] were: C-GENERAL = [final workload (W)/body weight (kg)] x 10.483 + 7; C-MEN = [final workload (W)/body weight (kg)] x 10.791 + 7; and C-WOMEN = [final workload (W)/body weight (kg)] x 9.820 + 7. The E% for MEN was: -3.4 ± 13.4% (modified ACSM); 1.2 ± 13.2% (C-GENERAL); and -0.9 ± 13.4% (C-MEN) (p < 0.01). For WOMEN: -14.7 ± 17.4% (modified ACSM); -6.3 ± 16.5% (C-GENERAL); and -1.7 ± 16.2% (C-WOMEN) (p < 0.01).Conclusion:The error of estimate of VO2max by use of sex-specific equations was reduced, but not eliminated, in exercise tests on LLCE.

FUNDAMENTO: Valores exagerados da pressão arterial sistólica (PAS) durante um teste cardiopulmonar de exercício máximo (TCPE) são classicamente considerados como inapropriados e associados a um maior risco para desenvolvimento de doenças cardiovasculares. Sabe-se que o sistema nervoso autônomo modula a PA no exercício. Contudo, não está claramente estabelecido o comportamento do tônus vagal cardíaco (TVC) em indivíduos saudáveis com uma resposta pressórica exagerada no TCPE. OBJETIVO: Analisar o comportamento do TVC em homens adultos saudáveis que apresentam uma resposta pressórica exagerada no TCPE. MÉTODOS: De 2.505 casos avaliados entre 2002-2009, foram identificados criteriosamente 154 casos de homens, entre 20-50 anos de idade, saudáveis e normotensos. A avaliação incluía exame clínico, medidas antropométricas, testes de exercício de 4 segundos (tônus vagal cardíaco) e TCPE realizado em cicloergômetro, com medidas de pressão arterial a cada minuto pelo método auscultatório. Baseado no valor máximo de PAS obtido no TCPE, a amostra foi dividida em tercis, comparando-se o TVC, a carga máxima e o VO2 máximo. RESULTADOS: Os valores de TVC diferiram entre os indivíduos que se apresentavam nos tercis inferior e superior para a resposta da PAS ao TCPE, respectivamente, 1,57 ± 0,03 e 1,65 ± 0,04 (média ± erro padrão da média) (p = 0,014). Os dois tercis também diferiam quanto ao VO2 máximo (40,7 ± 1,3 vs 46,4 ± 1,3 ml/kg-1.min-1; p = 0,013) e a carga máxima (206 ± 6,3 vs 275 ± 8,7 watts; p < 0,001). CONCLUSÃO: Uma resposta pressórica exagerada durante o TCPE em homens adultos saudáveis é acompanhada de indicadores de bom prognóstico clínico, incluindo níveis mais altos de condição aeróbica e de tônus vagal cardíaco.
BACKGROUND: Exaggerated systolic blood pressure (SBP) levels during a maximal cardiopulmonary exercise test (CPET) are classically considered as inappropriate and associated with a higher risk for the development of cardiovascular diseases. It is known that the autonomic nervous system modulates the BP during exercise. However, the behavior of the cardiac vagal tone (CVT) has not been fully established in healthy individuals with an exaggerated BP response to CPET. OBJECTIVE: To analyze the behavior of the CVT in healthy adult males presenting an exaggerated BP response to CPET. METHODS: Of the 2,505 cases evaluated between 2002-2009, 154 cases were thoroughly identified, consisting of healthy male normotensive subjects aged 20-50 years. The evaluation included clinical assessment, anthropometric measurements, 4-second exercise test (cardiac vagal tone) and cardiopulmonary exercise test (CPET) performed in a cycle-ergometer, with BP measurements being taken every minute through auscultation. Based on the maximum SBP value obtained at the CPET, the sample was divided in tertiles, comparing CVT, maximum workload and VO2 max. RESULTS: The CVT results differed between individuals in the lower tertile and upper tertile for the SBP response to the CPET, respectively: 1.57 ± 0.03 and 1.65 ± 0.04 (mean ± standard error of mean) (p = 0.014). The two tertiles also differed regarding the VO2 max (40.7 ± 1.3 vs 46.4 ± 1.3 ml/kg-1.min-1; p = 0.013) and the maximum workload (206 ± 6.3 vs 275 ± 8.7 watts; p < 0.001). CONCLUSIOn: An increased BP response during the CPET in healthy adult males is accompanied by indicators of good clinical prognosis, including higher levels of aerobic fitness and cardiac vagal tone.

OBJECTIVES: to determine if there are differences in cardiac vagal tone values in non-obese healthy, adult men with and without unfavorable anthropometric characteristics. INTRODUCTION: It is well established that obesity reduces cardiac vagal tone. However, it remains unknown if decreases in cardiac vagal tone can be observed early in non-obese healthy, adult men presenting unfavorable anthropometric characteristics. METHODS: Among 1688 individuals assessed between 2004 and 2008, we selected 118 non-obese (BMI <30 kg/m²), healthy men (no known disease conditions or regular use of relevant medications), aged between 20 and 77 years old (42 ± 12-years-old). Their evaluation included clinical examination, anthropometric assessment (body height and weight, sum of six skinfolds, waist circumference and somatotype), a 4-second exercise test to estimate cardiac vagal tone and a maximal cardiopulmonary exercise test to exclude individuals with myocardial ischemia. The same physician performed all procedures. RESULTS: A lower cardiac vagal tone was found for the individuals in the higher quintiles - unfavorable anthropometric characteristics - of BMI (p=0.005), sum of six skinfolds (p=0.037) and waist circumference (p<0.001). In addition, the more endomorphic individuals also presented a lower cardiac vagal tone (p=0.023), while an ectomorphic build was related to higher cardiac vagal tone values as estimated by the 4-second exercise test (r=0.23; p=0.017). CONCLUSIONS: Non-obese and healthy adult men with unfavorable anthropometric characteristics tend to present lower cardiac vagal tone levels. Early identification of this trend by simple protocols that are non-invasive and risk-free, using select anthropometric characteristics, may be clinically useful in a global strategy to prevent cardiovascular disease.

OBJETIVO: Determinar a viabilidade da utilização de traçado convencional de eletrocardiografia (ECG) para avaliação da atividade vagal cardíaca (AVC). MÉTODOS: Foram analisados, retrospectivamente, 1.395 indivíduos (995 homens), na faixa de idade de 46 + 17,2 anos (média ± desvio padrão), com traçados de ECG convencional para medida do Delta RR, que representa a diferença, em ms, entre o maior e o menor intervalo RR, e com resultados da avaliação autonômica parassimpática, o teste de exercício de quatro segundos (T4s), que quantifica a AVC por meio do índice vagal cardíaco (IVC). Foram obtidas curvas ROC para determinar os valores de Delta RR com melhor relação entre sensibilidade e especificidade para os pontos de corte de baixa e alta AVC, respectivamente, de 1,20 e 1,95. RESULTADOS: Os valores de delta RR correlacionaram-se significativamente com os de IVC (r = 0,40; p < 0,001). Foram identificados < 60 ms e > 120 ms como os melhores pontos de corte para baixa e alta AVC, com sensibilidade de 75% e 57%, especificidade de 62% e 79% e áreas das curvas ROC de 0,76 e 0,74, respectivamente. CONCLUSÃO: A medida visual do delta RR em um traçado de ECG parece ser válida para a avaliação clínica preliminar e rápida da AVC, podendo ser útil em consultórios, emergências ou situações nas quais o uso de métodos mais sofisticados de avaliação autonômica não seja viável, oportuno ou conveniente.
OBJECTIVE: To determine the viability of using a conventional electrocardiogram (ECG) tracing for assessment of CVA. METHODS: We retrospectively analyzed 1395 individuals (995 males), aged 46 ± 17.2 years (mean ± standard deviation) with conventional ECG tracings to measure the delta RR (which represents the difference in milliseconds (ms) between the greatest and smallest RR interval) and results of a second autonomic parasympathetic evaluation, the 4-second exercise test (T4s), that quantifies CVA by the cardiac vagal index (CVI). ROC curves were obtained to determine the values of Delta RR for a closer correlation with sensitivity and specificity for 1.20 and 1.95 ms, the low and high CVA cutoff points, respectively. RESULTS: The delta RR levels correlated significantly with those of the CVI (r=0.40; p<0.001). We identified < 60 and > 120 ms as the best cutoff points for low and high CVA. Sensitivity was 75% and 57%, specificity was 62% and 79%, and the areas of the ROC curves were 0.76 and 0.74, respectively. CONCLUSION: The visual measurement of delta RR on an ECG tracing seems to be a valid quick preliminary clinical evaluation of CVA and can be useful in medical offices, emergency units, or situations in which the use of more sophisticated methods may not be feasible, appropriate, or convenient.

Regular physical exercise is an important factor to reduce the indexes of cardiovascular and all causes morbimortality. However, there is, apparently, additional and independent benefits of the regular practice of physical exercise and the improvement of the level of aerobic condition. Heart rate (HR) is mediated primarily by the direct activity of the autonomic nervous system (ANS), specifically through the sympathetic and parasympathetic branches activities over the sinus node autorhythmicity, with predominance of the vagal activity (parasympathetic) at rest, that is progressively inhibited since the onset of the exercise. The HR behavior has been widely studied during different conditions and protocols associated to the exercise. A reduction of the cardiac vagal tone (parasympathetic function) and consequently a diminished HR variability in rest, independently of the protocol of measurement used, is related to an autonomic dysfunction, chronic-degenerative diseases and increased mortality risk. Individuals with high levels of aerobic condition have a lower resting HR, along with a larger parasympathetic activity or smaller sympathetic activity, but it is not necessarily a direct consequence of the exercise training, as long as other inherent adaptations to the aerobic conditioning can influence the resting HR. The HR response in the onset of the exercise represents the integrity of the vagus nerve, and the HR recovery on the post-exercise transient also denotes important prognostic information; by the way, individuals that have a slow HR recovery in the first minute post-exercise have increased mortality risk. In conclusion, the physiological mechanisms modulating HR during or after an exercise program are not totally clear, and further studies are needed.
