Objective: To describe the mortality trend from all causes of cancer and the five main causes in the state of Mato Grosso, Brazil, from 2000 to 2015. Methods: This is a descriptive, ecological, time series study, with data referring to deaths of residents of Mato Grosso due to neoplasms (ICD-10 codes C00 to C97), from the Mortality Information System (SIM). Time trend analyzes of the standardized mortality rate from all causes of cancer and five specific causes of cancer (lung, prostate, breast, colorectal and cervix) for the state and according to macroregions (South, West, North, East and Center -North) were performed using linear regression (p-value<0.05). Results: From 2000 to 2015, 28,525 deaths from all causes of cancer in residents of the state of Mato Grosso were recorded. An increasing trend was observed for all causes of cancer, in addition to lung, breast and colorectal cancers. Southern and Northern macroregions showed an increasing trend for all causes, breast and colorectal; North-Central for breast and colorectal. East was increasing for all causes, prostate and colorectal, and decreasing for cervix. Conclusions: In the state of Mato Grosso, there was an increasing trend in mortality from all causes of cancer and from specific causes, with emphasis on breast and colorectal cancer in most macroregions.

Objective: To estimate the mortality trend and analyze the potential years of life lost (PYLL) due to leukemias and lymphomas in Brazil and Mato Grosso, from 2001 to 2019. Methods: Time-series study of deaths from leukemias and lymphomas obtained from the Mortality Information System. Trends were calculated by age group by the Joinpoint regression method, using calendar year as regressor variable, and estimated annual percentage change (APC) and mean annual percentage change, considering 95% confidence intervals. APVP rates were collected from the Cancer Mortality Altas. Results: In Brazil, the mortality rate trend showed stability for both diseases, leukemias (APC=0.2; 95%CI-0.0;0.3) and lymphomas (APC=0.2; 95%CI-0.4;0.1). In the state, the rate for leukemias also showed stability (APC=0.3; 95%CI-1.0;1.6). For lymphomas, the trend was upward (APC=2.3; 95%CI0.5;4.2), however, decreasing trend was observed among those younger than 59 years. For leukemias, the APVP rates were 64 and 65/100,000 in Brazil and Mato Grosso, respectively. For lymphomas, these rates were 27 and 22/100,000, respectively, with the highest rates found in males. Conclusion: The mortality rates from leukemia and lymphoma in Mato Grosso show a behavior different from that observed nationally, with an increasing trend for lymphomas and no differences between age groups for both diseases. The APVP rates for leukemias were similar, however, for lymphomas, it was higher among men and lower for the state when compared to Brazil.

Para leucemias, as taxas de APVP foram de 64 e 65/100.000 no Brasil e no Mato Grosso, respectivamente. Para linfomas, esses valores foram de 27 e 22/100.000, respectivamente, sendo as maiores taxas encontradas no sexo masculino. Conclusão: As taxas de mortalidade por leucemias e linfomas no Mato Grosso apresentam comportamento diferente do observado nacionalmente, com tendência crescente para linfomas e sem diferenças entre as faixas etárias, para ambos os agravos. As taxas de APVP por leucemias foram semelhantes, no entanto, para os linfomas, foi maior entre os homens e menores para o estado, quando comparadas as do Brasil.

ABSTRACT Objective To evaluate the positioning of the distal tip of central venous catheters and the factors that contributed to inadequate positioning in patients admitted to intensive care. Methods This is a cross-sectional study, with a sample of 246 medical records of patients admitted to intensive care units. A catheter position analysis form was used as an instrument for data collection. Results It was seen that 86.2% of catheters used in intensive care were centrally inserted in the internal jugular veins, 74.4% were double-lumen catheter, and ultrasound was employed for puncture technique in 84.6% of cases. Of the distal ends of the catheters, 53.7% were at the cavoatrial junction (correct position). According to statistical tests, there was a positive correlation between the inadequate positioning of the distal extremity with the central insertion catheter (p=0.012). Patients with presumptive diagnosis associated with COVID-19 showed a positive correlation with inappropriate positioning of the catheter distal tip (p=0.017). Conclusion There are extrinsic factors related to improper positioning of the distal tip of catheters, such as the type of catheter used, the patients’ diagnosis and the puncture with insertion in the left jugular vein.

Abstract The pupunha (peach palm) palm heart production in the Vale do Ribeira (southern region of the State of São Paulo-Brazil) brings economic benefits to the region, and environmental risks with the generation of a large amount of waste. The Cleaner Production adoption in the pupunha palm heart factories is a strategy for reducing environmental impacts and generating profit, with consequent rational use of raw material, reuse of waste, and new equipment installation. This research aims to evaluate the Cleaner Production adoption’s environmental and economic benefits in the reuse of waste generated in pupunha palm heart processing. The case study was carried out in a factory, using direct observation, interviews, and documentary data. The calculation of ROI was an adequate tool for economic evaluation, and the adoption of gondolas in the stages of material separation and waste treatment provided improvements in the production processes. The Cleaner Production application increased the theoretical knowledge about the treatment and use of the waste, reduced the environmental impact, allowed the development of a new business, and generated economic gains through the creation of employment and increase of income.

ABSTRACT: Objective: To estimate the mortality trend and to analyze the potential years of life lost (PYLL) due to leukemias and lymphomas in Brazil and Mato Grosso, from 2001 to 2019. Methods: Time-series study on deaths from leukemias and lymphomas with data obtained from the Mortality Information System. Trends were calculated by age group by the Joinpoint regression method, using calendar year as regressor variable, estimated annual percentage change (APC) and mean annual percentage change, considering 95% confidence intervals. PYLL rates were collected from the Cancer Mortality Atlas. Results: In Brazil, the mortality rate trend remained stable for both diseases in the period: leukemias (APC=0.2; 95%CI 0.0–0.3) and lymphomas (APC=0.2; 95%CI 0.4–0.1). In Mato Grosso state, the rate for leukemias was also stable (APC=0.3; 95%CI 1.0–1.6). For lymphomas, the trend was ascendant (APC=2.3; 95%CI 0.5–4.2), but descending among people younger than 59 years. For leukemias, PYLL rates were 64 and 65/100,000 in Brazil and Mato Grosso, respectively. For lymphomas, 27 and 22/100,000, respectively, with the highest rates found among males. Conclusion: The behavior of mortality rates from leukemia and lymphoma in Mato Grosso was different from that observed nationally, with an upward trend for lymphomas and no differences between age groups for both diseases. PYLL rates for leukemias were similar, while for lymphomas they were higher among men and lower in Mato Grosso when compared to Brazil.

Qualea grandiflora Mart. (“pau-terra”) is a medicinal plant symbolic from Cerrado biome. Qualea species reportedly have antiparasitic properties, but their active compounds have yet to be identified. In this study, we investigated the antiplasmodial activity of Q. grandiflora fruit and stem extracts against Plasmodium falciparum. The polar extracts of both fruits and stems showed promising in vitro antiplasmodial activity against sensitive and resistant P. falciparum strains (half-maximal inhibitory concentration (IC50) = 1.2 and 4.2 ng mL-1, respectively), low cytotoxicity against human hepatic cells (IC50HepG2 ≥ 400 ng mL-1), and a noteworthy selectivity index (SI ≥ 322 and ≥ 96, respectively). The fruit ethanolic extract revealed significant oral efficacy at 100 mg kg-1 in a mouse model of P. berghei malaria (100% reduction in parasitemia on day 5 post-infection). To investigate the chemical composition of the extracts, we developed a method involving liquid chromatography-high resolution quadrupole-time of flight mass spectrometer. The chemical profiling of active extracts indicated 32 compounds, including gallotannins, ellagic acid derivatives and flavonoids. The common component in the active polar extracts was found to be ellagic acid (EA), which may contribute favorably to the in vitro and in vivo inhibitory activity observed in this study.

Abstract The high prevalence of anxiety disorders associated with pharmacotherapy side effects have motivated the search for new pharmacological agents. Species from Citrus genus, such as Citrus limon (sicilian lemon), have been used in folk medicine as a potential therapy to minimize emotional disorders. In order to searching for new effective treatments with fewer side effects, the present study evaluated the anxiolytic mechanism of action and the hypnotic-sedative activity from the Citrus limon fruit's peels essential oil (CLEO). Adults male Swiss mice were submitted to barbiturate-induced sleep test; elevated plus-maze (EPM) and light-dark box (LDB) (evaluation of the mechanism of action); rotarod; and catalepsy tests. CLEO oral treatment decreased latency and increased the sleep total time; moreover it induced in animals an increased the number of entries and percentage of time spent into open arms of the EPM; an increased the number of transitions and the percentage of time into light compartment in the LDB; which were only antagonized by flumazenil pretreatment, with no injury at motor function. Thus, results suggest that CLEO treatment induced an anxiolytic behavior suggestively modulated by the benzodiazepine binding site of the GABAA receptor or by an increase of GABAergic neurotransmission, without cause impairment in the motor coordination.

Abstract A new species of Diolcogaster (Hymenoptera: Braconidae) is described and illustrated. Additionally, its position within the recently published key to New World species of the xanthaspis species-group (to which the described Diolcogaster belongs) is provided. The gregarious larval parasitoid Diolcogaster choi sp. nov. was collected in Maringá, Paraná State, Brazil. This natural enemy was recovered from a caterpillar of Hypercompe cunigunda (Stoll, 1781) (Lepidoptera: Erebidae) that was feeding on plant of passionflower, Passiflora edulis Sims (Passifloraceae). The fauna of the xanthaspis group in the New World now includes five species, including the new species from Brazil described in this paper. Diolcogaster choi sp. nov. differs anatomically, and is morphologically diagnosed, from all other known member of the xanthaspis group of the genus Diolcogaster, to which it belongs. The species also differs in recorded host, and its DNA barcode appears to be distinctive among described Diolcogaster.

Abstract A new species of microgastrine wasp, Cotesia invirae Salgado-Neto & Whitfield, sp. nov., is described from southern Brazil in Santa Maria, Rio Grande do Sul. This species is a koinobiont gregarious larval endoparasitoid and spins a common mass of cocoons underneath the host caterpillars of Opsiphanes invirae (Huebner, 1818) (Lepidoptera: Nymphalidae), feeding on the palm trees Syagrus romanzoffianum (Cham.) Becc.; Livistona chinensis (N.J. Jacquim) R. Brown; Roystonea regia (HBK) O.F. Cook; Archontophoenix cunninghamiana Wendland & Drude (Palmaceae). Morphological, molecular, biological, ecological and geographical data are integrated to describe the new species.

RESUMO Diferentemente de outras variáveis mais comuns relacionadas à saúde, a aptidão cardiorrespiratória (ACR) não é medida constantemente na população em geral. Sua omissão caracteriza numa perda de informação relevante. Com isso os objetivos do presente estudo foram: a) caracterizar a ACR da população brasileira de 20 a 59 anos, desenvolvendo valores normativos através de uma equação para estimar o consumo máximo de oxigênio (VO2Máx) sem a realização de exercícios; e b) verificar a associação de menores níveis de ACR com a prevalência de doenças crônicas. Ao todo, 32.531 indivíduos compuseram a amostra oriunda da Pesquisa Nacional de Saúde (PNS-IBGE-2013). Apenas variáveis auto-relatadas foram incluídas a partir da equação de Wier et al. (2006): sexo, idade, nível de atividade física e Índice de Massa Corporal. A média de VO2Máx foi estimada como 44,6; 39,3; 34,8 e 30,6 ml/kg/min (homens) e 34,5; 29,6; 25,4 e 21,1 ml/kg/min (mulheres) com idades 20-29; 30-39; 40-49 e 50-59. Os valores de percentil 20 e 80 foram estabelecidos como os extremos de muito baixa e muito alta ACR. A baixa aptidão demonstrou significativamente 33% maiores chances de prevalência de doença cardiovascular, 89% de diabetes mellitus e 67% de hipertensão arterial independentemente de sexo, idade, e presença de obesidade, o que parece corroborar a qualidade da equação utilizada.

ABSTRACT Unlike other more common health-related variables, cardiorespiratory fitness (CRF) is not frequently measured in the general population. This omission characterizes a loss of relevant information. Thus, the objectives of the present study were: a) to characterize the CRF of the Brazilian population aged 20 to 59 years and to develop normative values using a non-exercise equation for predicting maximal oxygen uptake (VO2max), and b) to verify the association between lower levels of CRF and the prevalence of chronic diseases. A total of 32,531 individuals from the National Health Survey (NHS-IBGE-2013) composed the sample. Only self-reported variables were included in the equation of Wier et al. (2006): sex, age, physical activity level, and body mass index. The mean predicted VO2max was 44.6, 39.3, 34.8 and 30.6 ml/kg/min for men, and 34.5, 29.6, 25.4 and 21.1 ml/kg/min for women aged 20-29, 30-39, 40-49 and 50-59 years, respectively. The 20th and 80th percentiles were established as the extremes (very low and very high CRF). Participants with low fitness had a 33% higher chance of cardiovascular disease, an 89% higher chance of diabetes mellitus, and a 67% higher chance of hypertension, regardless of sex, age and presence of obesity, which seem to corroborate the quality of the equation.

Resumo O objetivo do presente estudo foi identificar o limiar de frequência cardíaca baseado na cinética da frequência cardíaca durante o exercício máximo graduado em jogadores de futebol. Vinte e seis jogadores de futebol masculino realizaram um teste de exercício máximo (protocolo de Bruce) em uma esteira motorizada. O consumo de oxigênio (VO2) e a freqüência cardíaca (FC) foram monitorados, registrados e reamostrados a 3,5Hz. O limiar ventilatório (LV), a compensação respiratória (CR), os pontos de deflexões da frequência cardíaca (PDFC1 e PDFC2) e o limiar da cinética da frequência cardíaca (LCFC) foram determinados por métodos computadorizados. A variabilidade da frequência cardíaca (VFC) foi avaliada no domínio da frequência. A média do LCFC foi de 89,9 ± 1,2% do VO2 de pico. O LCFC demonstrou correlações e diferenças significativas em relação ao PDFC1 (r = 0,46) e ao LV (r = 0,51), mas não foi diferente e altamente correlacionado com PDFC2 (0,98) e CR (0,90). Os gráficos de Bland Altman mostraram todos os atletas em 95% dos limites de concordância, e o coeficiente de correlação intraclasse apresentou boas concordâncias entre os pontos obtidos com o LCFC em comparação com o PDFC2 (0,96) e CR (0,98). A LCFC foi altamente correlacionada com PDFC2 e CR, sugerindo que poderia ser um marcador de fadiga cardiorrespiratória.

Abstract The main of the present study was to identify the heart rate threshold based on heart rate kinetics during graded maximal exercise in football players. Twenty-six male football players performed a maximal exercise test (Bruce protocol) on a motor-driven treadmill. Oxygen uptake (VO2) and heart rate (HR) were monitored, recorded and resampled at 3.5Hz. The ventilatory threshold (VT), and respiratory compensation (RC), heart rate deflection points (HRDP1 and HRDP2) and heart rate kinetics threshold (HRT) were determined by computerized methods. The heart rate variability (HRV) was assessed in the frequency domain. The HRT averaged 89.9 ± 1.2 % of the VO2 peak. The HRT showed poor correlations and significant differences compared with HRDP1 (r = 0.46) and VT (r = 0.51), but was not different from, and highly correlated with, HRDP2 (0.98) and RC (0.90). Bland Altman plots showed all athletes into 95% of limits of agreement, and intraclass correlation coefficient showed good agreements between points obtained from HRT compared with HRDP2 (0.96) and RC (0.98). The HRT was highly correlated with HRDP2 and RC, suggesting it could be a marker for cardiorespiratory fatigue.

Resumo A competência motora está associada a inúmeras variáveis relacionadas à saúde da população pediátrica. O presente estudo teve como objetivo analisar o efeito do nível de coordenação motora no desempenho em diversos testes de aptidão física de meninos pré-púberes, antes e depois de controlar o efeito exercido pela massa corporal. A amostra foi composta por 71 meninos brasileiros com oito anos de idade. A antropometria considerou a estatura, a massa corporal e as estimativas de gordura corporal e de massa magra. A maturação biológica foi avaliada pelo percentual da estatura matura predita. Os testes físicos aplicados foram o lançamento de medicineball 2-kg, preensão manual, abdominais em 60 segundos, salto horizontal, 10x5-m shuttle run, 20-m shuttle run e sentar e alcançar. A coordenação motora foi avaliada pelo Körperkoordinationtest für Kinder (KTK). Para análise dos dados, foi feita a estatística descritiva, a correlação de Pearson, o teste t-Student e a ANCOVA, com a massa corporal como covariável. O nível de significância adotado foi de p<0,05. Não houve diferença quanto ao estado maturacional entre os diferentes grupos de desempenho coordenativo. Os resultados evidenciaram que meninos com melhor desempenho em teste de coordenação motora estão associados aos melhores resultados em testes de aptidão física, nomeadamente naqueles que envolvem deslocamento da massa corporal. Esta tendência permaneceu mesmo quando foi realizada comparação entre ambos os grupos com o controle da massa corporal, com exceção do teste de abdominais. Pode-se concluir que a coordenação motora é preditora da aptidão física em meninos pré-púberes.

Abstract Motor competence is associated with numerous health-related variables of the pediatric population. The present study aimed to analyze the effect of the level of motor coordination on performance in several physical fitness tests in prepubertal boys, before and after controlling body mass. The sample consisted of 71 Brazilian eight-year-old boys. Anthropometry included stature, body mass and estimates of fat mass and fat-free mass. Biological maturation was evaluated by the percentage of predicted adult stature. The physical tests applied were 2-kg medicineball throw, handgrip strength, sit-ups in 60 seconds, standing long jump, 10x5-m shuttle run, 20-m shuttle run and sit and reach. Motor coordination was assessed by the Körperkoordinationtest für Kinder (KTK). For data analysis, descriptive statistics, Pearson correlation, Student’s t-test and ANCOVA were used, with body mass as covariate. Significance level was set at p <0.05. There was no difference in maturational level between the different groups of coordinative performance. The results showed that boys with better performance in motor coordination tests are associated with better results in physical fitness tests, especially those involving body mass displacement. This trend remained even when comparing groups controlling body mass, except for the sit-up test. Therefore, it could be concluded that motor coordination is a predictor of physical fitness in prepubertal boys.

RESUMO A prevenção de eventos cardiovasculares é um dos principais objetivos de um questionário de triagem para a prática de exercícios. O objetivo do estudo foi verificar a validade diagnóstica do questionário do ACSM/AHA (AAPQ), através da sensibilidade (SE) e especificidade (ES), e AUC (área sob a curva). Participaram do estudo 69 indivíduos (40 a 81 anos). Comparações entre sexo e categorias de idade foram realizadas. Não foi verificada diferença significativa. Contudo, a variação nas respostas positivas pareceu aumentar percentualmente, principalmente a partir dos 60 anos (de 78,6% a 100%). Os valores de SE do AAPQ foram altos (88,2%), sugerindo que grande parte dos indivíduos em que o resultado do instrumento foi positivo apresentava alguma contraindicação. Contudo, o valor da ES foi de apenas 13,5%, indicando que o questionário não foi capaz de identificar aqueles indivíduos sem contraindicação ao início de um programa de exercícios. Com isso, o instrumento teria uma baixa capacidade diagnóstica (AUC=0,51). Os resultados sugerem que o questionário apresenta baixa capacidade em identificar indivíduos aptos a iniciar um programa de exercícios.

ABSTRACT The prevention of cardiovascular events is one of the main objectives of a preexercise screening questionnaire. The aim of this study was to evaluate the diagnostic validity of ACSM/AHA questionnaire (AAPQ), through the Sensitivity (Se), Specificity (Sp) and AUC (area under the curve). The study included 69 subjects (40-81 years). Comparisons between sex and age categories were performed. There was no significant difference. However, the variation in positive responses seemed to increase in percentage terms, especially after 60 years (from 78.6% to 100%). The AAPQ Se values were high (88.2%) suggesting that the majority of individuals in whom the instrument was positive showed some contraindication. However, the Sp value was only 13.5%, indicating that the questionnaire was not able to identify those with no contra indication to start an exercise program. Thus, the instrument would have a low diagnostic capacity (AUC = 0.51). The results suggest that the questionnaire presents a low capacity to identify individuals suitable for inclusion in an exercise program.

ABSTRACT A new species of Diolcogaster (Ashmead, 1900) (Hymenoptera: Braconidae) is described and illustrated. Additionally, a key to all New World species formally published of the xanthaspis species-group (to which the new species belongs) is provided. The solitary larval parasitoid Diolcogaster flammeus sp. nov. was collected in Viçosa, Minas Gerais State, Brazil. This natural enemy was reared from caterpillars of Agaraea minuta (Schaus, 1892) (Lepidoptera: Erebidae) feeding on plants of spiked spiralflag ginger, Costus spicatus (Jacq.) Sw. and ginger spiral, Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae). The fauna of the xanthaspis group in the New World included just three published species prior to this publication. Diolcogaster flammeus sp. nov. is the only yellow-orange species of the xanthaspis group recorded in the New World thus far.
