Abstract Conscientious objection is defined as the right to refuse the practice of an act of his profession, when this action conflicts with their conscience, offending his ethical, moral, religious, philosophical, ideological, or humanitarian principles. This was called into question in the report entitled “The situation of sexual and reproductive health and rights in the EU, in the frame of women’s health”, better known as the Matic Report, approved by the European Parliament. In this report, it was proposed to consider “conscientious objection as a refusal to provide medical care”. However, this is a right that should be considered inalienable. It is necessary to guarantee not only the autonomy of the patient but also that of the health care professional.

Resumo A objeção de consciência é referida como o direito de o médico recusar a prática de ato próprio da sua profissão quando essa mesma prática entre em conflito com a sua consciência, ofendendo os seus princípios éticos, morais, religiosos, filosóficos, ideológicos ou humanitários. O direito em questão foi posto em causa no relatório “A situação da saúde e dos direitos sexuais e reprodutivos da UE, no contexto da saúde das mulheres”, vulgarmente conhecido como Relatório Matic, aprovado pelo Parlamento Europeu. No referido documento propôs-se a consideração da “objeção de consciência como uma recusa de prestação de cuidados médicos”. No entanto, aquela deve ser considerada um direito inalienável. Neste sentido, e no âmbito desta problemática, é necessário garantir não só a autonomia do doente, como também a do próprio profissional de saúde, procurando um equilíbrio entre ambas.

Abstract In 2019, the OECD counted more than 3 million preventable deaths among people under the age of 75, about a quarter of all deaths accounted for. The main cause of preventable mortality in 2019 was malignant tumors (31%), among which lung cancer stands out. The main causes of treatable death in 2019 were diseases of the circulatory system. In Portugal, in 2019, the main causes of death were also diseases of the circulatory system (29.9%), followed by malignant tumors (25.4%), and by diseases of the respiratory system (10.9%). The average age-standardized mortality rate from preventable causes was 126 deaths per 100,000 people in OECD countries. In Portugal, this rate was 109, which leaves us below the OECD average. Mortality rates from treatable causes in OECD countries were lower, with an average of 73 per 100,000 inhabitants, Portugal was below the OECD with 64. Preventable mortality rates in OECD countries were 2.5 times higher among men than among women. After 2020 and with the COVID-19 pandemic, there will certainly be a major impact on preventable mortality.

Resumo Em 2019, na OCDE foram contabilizadas mais de três milhões de mortes que poderiam ter sido evitadas entre pessoas com menos de 75 anos, cerca de um quarto da totalidade das mortes contabilizadas. A principal causa de mortalidade prevenível em 2019 foi o tumor maligno (31%), entre o qual se destaca o cancro do pulmão. As principais causas de morte tratáveis em 2019 foram as doenças do sistema circulatório. Em Portugal, no ano de 2019, as principais causas de morte foram também as doenças do sistema circulatório (29,9%), seguidas pelos tumores malignos (25,4%) e pelas doenças do aparelho respiratório (10,9%). No referido ano, a taxa média de mortalidade padronizada por idade por causas evitáveis foi de 126 mortes por 100.000 pessoas nos países da OCDE. Em Portugal, esta taxa foi de 109, o que nos deixa abaixo da média da OCDE. As taxas de mortalidade por causas tratáveis nos países da OCDE foram mais baixas, com uma média de 73 por 100.000 habitantes; Portugal ficou abaixo da OCDE com 64. As taxas de mortalidade preveníveis nos países da OCDE foram 2,5 vezes maiores entre os homens do que entre as mulheres. Após 2020 e com a pandemia por COVID-19 constatar-se-á, certamente, um grande impacto na mortalidade evitável.

Humankind has experienced a remarkable development since it began to design and optimize chemical reactions to achieve valuable compounds. The key to accomplish these tasks is the proper understanding of how chemical transformations occur at a molecular level, that is, their reaction mechanisms. Based on a suitable mechanistic proposal, experimentalists choose a given chemical protocol to optimize experimental conditions, design new synthetic routes, and circumvent competing reactions. In this context, computational chemistry has become a valuable ally for mechanistic elucidation. We present herein a review of complementary collaborations between experimentalists and theoretical chemists to rationalize processes at the molecular level, focusing mainly on the fields of organic synthesis, natural product chemistry, and systems with environmental interest. Throughout this review, we highlight the ability of computational evaluations to provide answers to questions raised from experiments in a clear and direct way, indicating to experimentalists alternative paths to help them solve their problems. compounds level mechanisms proposal conditions routes context elucidation synthesis interest way problems

Abstract This article aims to investigate the association between maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) with the incidence of frailty syndrome (FS), in addition to testing the predictive ability of MIP and MEP to discriminate FS in elderly adults, according to sex. It is a longitudinal study with a five-year follow-up period (2014-2019), carried out with 104 elderly adults registered in the Family Health Strategy of a municipality in Bahia. The incidence of frailty syndrome was diagnosed according to criteria proposed by Fried et al., using data from 2019, after a five-year follow-up. The MIP and MEP were evaluated according to the recommendations of the Brazilian Society of Pulmonology and Phthisiology data in 2014 (baseline data). The total incidence of frailty syndrome was 16.3% (95%CI: 9.2-23.6), with 13.6% (95%CI: 4.56-22.55) in women and 20% (95%CI: 7.85-32.15) in men. The mean values of MIP and MEP were, respectively, 60,8±21,2 cmH2O and 76,7±23,1 cmH2O in women, and 79,5±27,0 cmH2O and 114,7±29,8 cmH2O in men. The frailty syndrome was associated with MEP in elderly adult men (adjusted RR: 0.96; 95%CI: 0.95-0.98; P-value: 0.002), indicating that the increase of 1cmH2O in MEP reduces by 4% the risk of developing the syndrome.

RESUMO Objetivo: Comparar as pressões respiratórias máximas e parâmetros espirométricos entre idosos classificados como sem sarcopenia, sarcopenia provável e sarcopenia confirmada e testar a capacidade dessas variáveis de discriminar sarcopenia em idosos residentes em comunidade. Métodos: Estudo transversal envolvendo 221 idosos (≥ 60 anos) de ambos os sexos. Sarcopenia foi diagnosticada de acordo com o novo consenso do Grupo de Trabalho Europeu sobre Sarcopenia em Pessoas Idosas. As pressões respiratórias máximas e parâmetros espirométricos foram avaliados. Resultados: As prevalências de sarcopenia provável e sarcopenia confirmada foram de 20,4% e 4,1%, respectivamente. Independentemente do sexo, aqueles com sarcopenia confirmada apresentaram PEmáx significativamente menor do que aqueles sem sarcopenia e provável sarcopenia, enquanto apenas os homens com sarcopenia confirmada apresentaram PImáx significativamente menor do que os outros indivíduos. Houve uma associação inversa de PImáx e PEmáx com sarcopenia, indicando que a diminuição de 1 cmH2O nesses parâmetros aumenta a chance de sarcopenia em 8% e 7%, respectivamente. Os parâmetros espirométricos não foram associados à sarcopenia. Os pontos de corte para PImáx e PEmáx, respectivamente, foram ≤ 46 cmH2O e ≤ 50 cmH2O para mulheres idosas, enquanto foram ≤ 63 cmH2O e ≤ 92 cmH2O para homens idosos, e ambas foram identificadas como preditores de sarcopenia (ASC ROC > 0,70). Conclusões: A sarcopenia associou-se a pressões respiratórias máximas mais baixas, mas não a parâmetros espirométricos. As pressões respiratórias máximas podem ser usadas como marcadores de sarcopenia em idosos residentes em comunidade, independentemente do sexo.

ABSTRACT Objective: To compare maximum respiratory pressures and spirometric parameters among elderly individuals classified as having no sarcopenia, probable sarcopenia, and confirmed sarcopenia, and to test the ability of these variables to discriminate sarcopenia in a community-dwelling elderly population. Methods: This was a cross-sectional study involving 221 elderly (≥ 60 years of age) individuals of both sexes. Sarcopenia was diagnosed in accordance with the new consensus of the European Working Group on Sarcopenia in Older People. Maximum respiratory pressures and spirometry parameters were assessed. Results: The prevalences of probable sarcopenia and confirmed sarcopenia were 20.4% and 4.1%, respectively. Regardless of the sex, those with confirmed sarcopenia had significantly lower MEP than those with no sarcopenia and probable sarcopenia, whereas only males with confirmed sarcopenia presented with significantly lower MIP than did the other individuals. There was an inverse association of MIP and MEP with sarcopenia, indicating that the decrease by 1 cmH2O in these parameters increases the chance of sarcopenia by 8% and 7%, respectively. Spirometric parameters were not associated with sarcopenia. Cutoff points for MIP and MEP, respectively, were ≤ 46 cmH2O and ≤ 50 cmH2O for elderly women, whereas they were ≤ 63 cmH2O and ≤ 92 cmH2O for elderly men, and both were identified as predictors of sarcopenia (area under the ROC curve > 0.70). Conclusions: Sarcopenia was associated with lower maximum respiratory pressures, but not with spirometric parameters. Maximum respiratory pressures can be used as markers of sarcopenia in a community-dwelling elderly population regardless of the sex.

Abstract To improve the wear resistance of cutting tools made of high-speed steel, the Diamond-Like Carbon (DLC) coating appears as a promising alternative. There are several methods to assess wear, however, it is a challenge for manufacturing engineering to work with thin films, due to the uncertainty in the boundary of the substrate and the coating. Based on this concern, this study proposed the evaluation of the tribological behavior of the DLC coating deposited on AISI M35 steel, seeking to predict its behavior in machining conditions based on characterizations, nano-indentation, micro-abrasion and ball-on-disc test. Results showed that the DLC coating produced for this study consists mainly of sp2 hybridizations. The results of the nano-indentation showed that DLC coating may have a better wear resistance when compared to high-speed steel, and the nano-hardness and Young's modulus do not necessarily obey a positive correlation. Compared to high-speed steel, DLC provided reductions of 71% and 69% without micro-abrasive wear and without friction coefficient during sliding, respectively.

Abstract Aim: Anthropometry represents an alternative to the evaluation of nutritional status and screening of events related to muscle fitness. Therefore, this study aimed to compare anthropometric indicators of postmenopausal women with and without dynapenia and to identify the predictive capacity of these indicators to screen the respective outcome in this population. Methods: Cross-sectional epidemiological study, conducted with postmenopausal women. Dynapenia was diagnosed by handgrip strength < 20 kgf. Arm (AC), abdominal (AbC), hip (HC) and calf circumferences (CC), triceps, biceps, subscapular, supraspinatus and thigh skinfolds were analyzed. Body Mass Index, Conicity Index (CI), Body Adiposity Index (BAI), Waist to Hip and Waist to Height Ratio (WHtR), Corrected Arm Muscle Area (CAMA) and Arm Muscle Circumference (AMC) were calculated. Results: A total of 273 women participated in the study. The BAI, WHtR, and CI did not present significant differences between the groups. For the other indicators, the dynapenic group obtained significantly lower values compared to the non-dynapenic. AC was the indicator with the highest sensitivity to screen for postmenopausal dynapenia (79.8%). While CAMA and AMC were the indicators with the best specificity (86.2%). However, CC showed the best balance between sensitivity (67.5%) and specificity (63.0%). Conclusion: The indicators AC, CAMA, and/or the AMC can be used together, or CC alone, to predict postmenopausal women with dynapenia. Therefore, these indicators can be used as important epidemiological tools to improve women's health surveillance actions.

Abstract Carioca grains are the most cultivated commercial group of common bean and Fusarium oxysporum f. sp. phaseoli (Fop) is an important disease under field conditions. Genetic resistance is the most effective control strategy. Thus, our objective was to study the inheritance of Fop resistance in the carioca grain type common bean. Lines CNFC 11965 (S) and CVIII 8511 (R) were crossed to obtain F1 and F2 generations and backcrosses, inoculated with the isolate FOP UFV 01, and severity grades used to estimate genetic parameters. Segregation of resistant and susceptible plants in the F2 generations and backcrosses resulted in dominant monogenic inheritance of Fop resistance. The high values of heritability emphasized the probability of success in the selection processes because environmental factors were not significant. The carioca grain line CVIII 8511 is promising, and its Fop resistance gene can be transferred to commercial cultivars of this group using the backcross method.

Abstract Aim: This study aimed to identify the prevalence and factors associated with dynapenia in older women, considering different cutoff points as diagnostic criteria. Methods: This epidemiological study was conducted with 205 older women (72.7 ± 7.1 years). Dynapenia was diagnosed using the handgrip strength test (HGS) using two cutoff points (< 16 or < 20 kgf). Socio-demographic, behavioral, and health status information was obtained from a specific form; nutritional status was assessed by body mass index, and the International Physical Activity Questionnaire identified the level of physical activity. Results: The prevalence of dynapenia was 14.1% (HGS < 16 kgf) and 46.3% (HGS < 20 kgf) (p < 0.001). It was also observed that older women with family income ≤ 1 minimum wage and those with low weight presented, respectively, 2.22 (95%CI: 1.12-4.39) and 4.72 (95%CI: 1.64-13.58) times higher probability of dynapenia identified by HGS < 16 kgf. Moreover, for the cutoff point < 20 kgf, the probability of dynapenia was higher in women aged ≥ 80 years (PR:1.91; 95%CI: 1.23-2.95), in insufficiently active women (PR: 1.34; 95%CI: 1.01-2.57), among those with low weight (PR: 1.61; 95%CI: 1.01-2.57), and in those who reported falls (PR:1.42; 95%CI: 1.04-1.96). Conclusion: Therefore, it is concluded that there is a difference between the prevalence and factors associated with dynapenia when different cutoff points are adopted.

RESUMO Objetivo Comparar a composição corporal de mulheres na pós-menopausa com e sem dinapenia a partir de diferentes pontos de corte. Métodos A composição corporal foi avaliada por bioimpedância elétrica e o estado nutricional pelo índice de massa corporal. A dinapenia foi diagnosticada por meio da força de preensão manual, utilizando-se os seguintes pontos de corte: força de preensão manual <16kgf e <20kgf. Resultados Participaram da pesquisa 171 mulheres (50 a 92 anos). A média de idade das não dinapênicas e das dinapênicas (força de preensão manual <20 kgf) foi 69,4±8,2 e 74,5±8,2 anos, respectivamente. As mulheres com dinapenia pela força de preensão manual <16kgf apresentaram média de idade de 75,0±10,1 anos e as não dinapênicas tinham, em média, 71,1±8,2 anos. Verificou-se que as mulheres dinapênicas, com força de preensão manual <20 e <16kgf, tinham em média 2,38 e 2,47kg a menos de massa muscular quando comparadas às não dinapênicas (p<0,05). Contudo, não foi observada diferença na massa muscular entre os diferentes grupos dinapênicos. As mulheres não dinapênicas (força de preensão manual ≥20kgf) apresentaram maior gordura total (3,55kg) e central (1,47kg) (p<0,05). Conclusão As mulheres dinapênicas, diagnosticadas por ambos os pontos de corte, apresentaram menor massa muscular total e por segmento em relação às não dinapênicas. Ademais, as dinapênicas com força de preensão manual <20kgf possuíam menor adiposidade total e no tronco.

ABSTRACT Objective To compare body composition of postmenopausal women with and without dynapenia, defined by different cut-off points. Methods Body composition was assessed by electrical bioimpedance and the nutritional status by the body mass index. Dynapenia was diagnosed according to handgrip strength, using the following cut-off points: handgrip strength <16kgf and <20 kgf. Results A total of 171 women (50 to 92 years of age) participated in the investigation. The mean age of non-dynapenic and dynapenic women (handgrip strength <20kgf) was 69.4±8.2 and 74.5±8.2 years, respectively. The mean age of women with dynapenia (handgrip strength <16kgf) was 75.0±10.1 years and non-dynapenic women, 71.1±8.2 years. It was found that dynapenic women, with handgrip strength <20 and <16kgf, had an average of 2.38 and 2.47kg less muscle mass respectively, when compared to non-dynapenic women (p<0.05). However, there was no difference in muscle mass between the different dynapenic groups. Non-dynapenic women (handgrip strength ≥20kgf) had more total (3.55kg) and central fat (1.47kg) (p<0.05). Conclusion Dynapenic women, diagnosed considering both cutoff points, had less total and segmental muscle mass compared to non-dynapenic women. In addition, dynapenic women with handgrip strength <20kgf had lower total and trunk adiposity.

Abstract Associated with the use of removable prostheses, the development of candidiasis, called prosthetic stomatitis, is frequently observed. In view of the application of silver nanoparticles (AgNP) in dentistry that may offer antimicrobial effect, the aim of this study was to evaluate the effect of adding AgNP with different concentrations during thermopolymerization or immersion of acrylic in this substance in the properties antifungal, mechanical and cytotoxic. The groups were divided: addition of 1% silver nanoparticle solution (G1), addition of 2.5% silver nanoparticle solution (G2), addition of 5% silver nanoparticle solution (G3), immersed for 10 min in aqueous silver nanoparticle solution (G4), immersed for 24 hours in aqueous silver nanoparticle solution (G5). In the cytotoxicity assay, at all evaluation times, all groups showed cytotoxic effect (p <0.05) when compared to the control group (CG). For the microbiological assay, C. albicans reduction was observed only for G4 and G5 when compared to CG (p <0.05). The lowest resistance values were observed in the group with 5% silver nanoparticle (G3) incorporation (p <0.05). It was concluded that the thermopolymerized acrylic resin immersed in AgNP, G4 and G5 promoted microbiological reduction, cytotoxicity increase and flexural strength decrease at 5% concentration.

Abstract Herbicides are agrochemicals applied in the control of weeds. With the frequent and repetitive use of these substances, serious problems have been reported. Compounds of natural origin and their derivatives are attractive options to obtain new compounds with herbicidal properties. By aiming to develop compounds with potentiated herbicidal activity, phenoxyacetic acids were synthesized from eugenol and guaiacol. The synthesized compounds were characterized and the herbicidal potential of phenoxyacetic acids and precursors was evaluated through bioassays regarding the germination and initial development of Lactuca sativa and Sorghum bicolor seedlings, with the induction of DNA damage. The induction of changes in the mitotic cycle of meristematic cells of roots of L. sativa was also analyzed. At the concentration of 3 mmol L-1, phenols and their respective phenoxyacetic acids presented phytotoxic and cytotoxic activities in L. sativa and S. bicolor. Eugenol and guaiacol also presented genotoxic action in L. sativa. The toxic effect of eugenoxyacetic acid was more pronounced in L. sativa than in S. bicolor, similar to the commercial 2,4-D herbicide. Molecular properties of the phenols and their derivatives phenoxyacetic acids were compared with the ones obtained for the herbicide 2,4-D, where it was found a correlation between their molecular properties and bioactivity.
