RESUMO

Germination is a simple and cost-effective technology that enhances the technological, sensory, and nutritional potential of grains, making them more attractive for use in the food industry. Germinating indigenous seeds is an alternative to increase noticeability and add value to these grains, which hold social and economic significance in the regions where they are cultivated, such as creole purple pericarp corn (PPCC) from the Couto Magalhães de Minas region in Brazil. This study aimed to optimize the germination parameters of time (24-96 h) and temperature (18-32 °C) for PPCC to produce water-soluble extracts and bread. Endogenous enzymes resulting from the germination process significantly enhanced (p < 0.10) the technological (total reducing sugars, total soluble solids, and soluble proteins) and biological properties (γ-aminobutyric acid, total soluble phenolic compounds, and antioxidant capacity) of the water-soluble extracts. The optimum point for obtaining the extracts was found to be at 85.3 h at 30.46 °C (with desirability of 90.42%), and this was statistically validated. The incorporation of germinated PPCC flours into bread was also promising (p < 0.10) and had a positive impact on the dough property (dough volume increase) and the final product, especially in terms of instrumental texture (springiness, cohesiveness, gumminess, chewiness, and resilience), resulting in a softer texture (lower firmness and hardness). The addition of PPCC flours did not alter instrumental color parameters, which may lead to greater consumer acceptance due to imperceptible differences in color to untrained individuals, with the optimized point at 96 h at 29.34 °C, with a desirability of 92.60%. Therefore, germinated PPCC shows promise for use as a base for obtaining water-soluble extracts and in bread as a replacement for commercial flour improvers, while also adding value to a raw material that is part of the local culture and agrobiodiversity.

RESUMO

Ryegrass is one such cereal that has been underutilized in human nutrition despite its high nutritional and functional value due to the presence of phytochemicals and dietary fibers. Exploiting ryegrass for human consumption is an exciting option, especially for countries that do not produce wheat, as it is easily adaptable and overgrows, making it economically viable. This study evaluated the nutritional content of γ-aminobutyric acid and bioactive compounds (total soluble phenolic compounds) and the physicochemical and technological properties of partially substituting maize flour (MF) with sprouted whole ryegrass flour (SR) in developing extrusion-cooked breakfast cereals. A completely randomized design with substitutions ranging from 0 to 20% of MF with SR was employed as the experimental strategy (p < 0.05). Partial incorporation of SR increased the content of γ-aminobutyric acid and total soluble phenolic compounds. Using sprouted grains can adversely affect the technological quality of extruded foods, mainly due to the activation of the amylolytic enzymes. Still, ryegrass, with its high dietary fiber and low lipid content, mitigates these negative effects. Consequently, breakfast cereals containing 4 and 8% SR exhibited better physicochemical properties when compared to SR12, SR16, SR20, and USR10, presenting reduced hardness and increased crispness, and were similar to SR0. These results are promising for ryegrass and suggest that combining the age-old sprouting process with extrusion can enhance the nutritional quality and bioactive compound content of cereal-based breakfast products while maintaining some technological parameters, especially crispiness, expansion index, water solubility index, and firmness, which are considered satisfactory.

RESUMO

Mycobacterium bovis BCG is the only vaccine against tuberculosis. The variable forms of cultivation throughout the years, before seed-lots were developed, allowed in vitro evolution of the original strain, generating a family of vaccines with different phenotypic and genotypic characteristics. Molecular studies revealed regions of difference (RDs) in the genomes of the various BCG strains. This work aims to characterize the gene pair rv3407-rv3408 (vapB47-vapC47), coding for a toxin-antitoxin system of the VapBC family, and to evaluate possible transcriptional effects due to the adjacent BCG Moreau-specific genomic deletion RD16. We show that these genes are co-transcribed in BCG strains Moreau and Pasteur, and that the inactivation of an upstream transcriptional repressor (Rv3405c) due to RD16 has a polar effect, leading to increased vapBC47 expression. Furthermore, we detect VapB47 DNA binding in vitro, dependent on a 5' vapB47 sequence that contributes to a palindrome, spanning the promoter and coding region. Our data shed light on the regulation of VapBC systems and on the impact of the BCG Moreau RD16 deletion in the expression of adjacent genes, contributing to a better understanding of BCG Moreau physiology.

RESUMO

Future predictions due to climate change are of decreases in rainfall and longer drought periods. The search for new tolerant crops is an important strategy. The objective of this study was to evaluate the effect of water stress on the physiology and productivity of crops with potential for growing in the off-season period in the Cerrado, and evaluate correlations with the temperature of the canopy obtained by means of thermography. The experiment was conducted under field conditions, with experimental design in randomized blocks, in a split-plot scheme and four replications. The plots were: common bean (Phaseolus vulgaris); amaranth (Amaranthus cruentus); quinoa (Chenopodium quinoa); and buckwheat (Fagopyrum esculentum). The subplots were composed of four water regimes: maximum water regime (WR 535 mm), high-availability regime (WR 410 mm), off-season water regime (WR 304 mm) and severe water regime (WR 187 mm). Under WR 304 mm, the internal concentration of CO2 and photosynthesis were reduced by less than 10% in amaranth. Common bean and buckwheat reduced 85% in photosynthesis. The reduction in water availability increased the canopy temperature in the four crops and, in general, common bean was the most sensitive species, while quinoa had the lowest canopy temperatures. Furthermore, canopy temperature correlated negatively with grain yield, biomass yield and gas exchange across all plant species, thus thermal imaging of the canopy represents a promising tool for monitoring crop productivity for farmers, For the identification of crops with high water use management for research.

RESUMO

Bioprospecting and synthesis of strategically designed molecules have been used in the search for drugs that can be in leishmaniasis. Hydrazones (HDZ) are promising compounds with extensive biological activities. The objective of this work was to perform in silico studies of hydrazones 1-5 and to evaluate their antileishmanial, cytotoxic and macrophage immunomodulatory potential in vitro. Hydrazones were subjected to prediction and molecular docking studies. Antileishmanial protocols on promastigotes and amastigotes of Leishmania amazonensis, cytotoxicity and macrophage immunomodulatory activity were performed. Hydrazones showed a good pharmacokinetic profile and hydrazone 3 and hydrazone 5 were classified as non-carcinogenic. Hydrazone 5 obtained the best conformation with trypanothione reductase. Hydrazone 1 and hydrazone 3 obtained the best mean inhibitory concentration (IC50) values for promastigotes, 4.4-61.96 µM and 8.0-58.75 µM, respectively. It also showed good activity on intramacrophagic amastigotes, with hydrazone 1 being the most active (IC50 = 6.79 µM) with selectivity index of 56. In cytotoxicity to macrophages hydrazone 3 was the most cytotoxic (CC50 = 256.3 ± 0,04 µM), while hydrazone 4 the least (CC50 = 1055.9 ± 0.03 µM). It can be concluded that the hydrazones revealed important pharmacokinetic and toxicological properties, in addition to antileishmania potential in reducing infection and infectivity in parasitized macrophages.

RESUMO

Individuals with Parkinson's disease (PD) present respiratory dysfunctions, mainly due to decreased chest wall expansion, which worsens with the course of the disease. These findings contribute to the restrictive respiratory pattern and the reduction in chest wall volume. According to literature, inspiratory muscle thixotropic conditioning maneuvers may improve lung volumes in these patients. The study aimed to determine the after-effects of respiratory muscle thixotropic maneuvers on breathing patterns and chest wall volumes of PD. A crossover study was performed with twelve patients with PD (8 males; mean age 63.9±8.8 years, FVC%pred 89.7±13.9, FEV1%pred 91.2±15, FEV1/FVC%pred 83.7±5.7). Chest wall volumes were assessed using OEP during thixotropic maneuvers. Increases in EIVCW (mean of 126mL, p = 0.01) and EEVCW (mean of 150mL, p = 0.005) were observed after DITLC (deep inspiration from total lung capacity) due to increases in pulmonary (RCp) and abdominal (RCa) ribcage compartments. Changes in ICoTLC (inspiratory contraction from TLC) led to significant EIVCW (mean of 224mL, p = 0.001) and EEVCW (mean of 229mL, p = 0.02) increases that were mainly observed in the RCp. No significant changes were found when performing DERV (deep expiration from residual volume) and ICoRV (Inspiratory contraction from RV). Positive correlations were also observed between the degree of inspiratory contraction during ICoTLC and EEVRCp (rho = 0.613, p = 0.03) and EIVRCp (rho = 0.697, p = 0.01) changes. Thixotropy conditioning of inspiratory muscles at an inflated chest wall volume increases EIVCW and EEVCW in the ten subsequent breaths in PD patients. These maneuvers are easy to perform, free of equipment, low-cost, and may help patients improve chest wall volumes during rehabilitation.

RESUMO

The COVID-19 pandemic, caused by SARS-CoV-2, had its first cases identified in late 2019 and was considered a clinical pandemic in March 2020. In March 2022, more than 500 million people were infected and 6,2 million died as a result of this disease, increasingly associated with changes in human hemostasis, such as hypercoagulation. Numerous factors contribute to the hypercoagulable state, and endothelial dysfunction is the main one, since the activation of these cells can strongly activate platelets and the coagulation system. In addition, there is a dysregulation of the renin-angiotensin system due to the SARS-CoV-2 takeover of the angiotensin converting enzyme 2, resulting in a strong immune response that could further damage the endothelium. Thrombus formation in the pulmonary microvasculature structure in patients with COVID-19 is an important factor to determine the severity of the clinical picture and the outcome of this disease. This review describes the hemostatic changes that occur in SARS-CoV-2 infection, to further improve our understanding of pathogenic mechanisms and the interaction between endothelium dysfunction, kallikrein-kinins, renin angiotensin, and the Coagulation/fibrinolysis systems as underlying COVID-19 effectors. This knowledge is crucial for the development of new effective therapeutic approaches, attenuating the severity of SARS-CoV-2's infection and to reduce the deaths.

RESUMO

Introdução: A segurança do paciente é considerada uma prioridade global pela Organização Mundial da Saúde, e o Brasil, como país-membro, lançou, em 2013, o Programa Nacional de Segurança do Paciente, recomendando práticas seguras para todos os serviços de saúde. Embora obrigatório, muitos estabelecimentos não possuem Núcleos de Segurança do Paciente estruturados para o gerenciamento de seus riscos e incidentes. Objetivo: Descrever a experiência na implantação de um programa de segurança para pacientes submetidos a procedimentos hemodinâmicos. Métodos: Estudo observacional, descritivo e retrospectivo da criação do Núcleo de Segurança do Paciente e do programa de gerenciamento de riscos. Resultados: O núcleo foi constituído em 2014, e o programa foi desenvolvido em quatro fases: criação do plano de segurança, mapeamento de riscos, criação de instruções de trabalho e gerenciamento de incidentes. Entre dezembro de 2014 e dezembro de 2019, foram monitorados 6.913 pacientes e identificado 146 incidentes, sendo 44,52% classificados como inconformidade a protocolos, 20,54% como circunstância notificável, 13,69% como quase-erro, 10,95% como incidente sem dano e 10,27% como evento adverso (incidente com dano). Entre 2017 e 2019, observaram-se redução no número de inconformidade de protocolo (0,66% versus 0,42%; p=0,01) e circunstância notificável (0,5% versus 0,32%; p=0,32), com incremento na comunicação de quase erro (0% versus 0,07%; p=0,018). Ao longo do estudo, observou-se aumento na adesão às metas dos indicadores relacionados à notificação de incidentes, ao tempo porta-balão e às horas- treinamento. Conclusão: A criação do Núcleos de Segurança do Paciente, somada à incorporação de um plano efetivo, é ferramenta efetiva, que contribui para a construção de uma cultura de excelência.


Background: Patient safety is considered a global priority by the World Health Organization, and Brazil, as a Member State, launched the National Patient Safety Program in 2013, recommending safe practices for all health services. Although mandatory, many facilities do not have structured Patient Safety Units to manage their risks and incidents. Objective: To describe the experience in implementing a safety program for patients undergoing invasive cardiology procedures. Methods: This was an observational, descriptive, and retrospective study on the creation of a patient safety unit and a risk management program. Results: The unit was established in 2014, and the program was developed in four phases: creation of the safety plan, risk mapping, creation of work instructions, and incident management. Between December 2014 and December 2019, a total of 6,913 patients were monitored and 146 incidents were identified, with 44.52% classified as non-compliance to protocol, 20.54% as reportable circumstances, 13.69% as near-misses, 10.95% as no harm incidents, and 10.27% as adverse events (harmful incidents). Between 2017 and 2019, there was a reduction in amount of non-compliance to protocol (0.66% versus 0.42%; p=0.01) and reportable circumstances (0.5% versus 0.32%; p=0.32), with an increase in near-miss reporting (0% versus 0.07%; p=0.018). Throughout the study, there was an increase in adherence to indicator targets related to incident reporting, door-to-balloon time, and training hours. Conclusion: The creation of Patient Safety Units, together with employing an effective plan, is an effective tool that contributes to the construction of a culture of excellence.

RESUMO

COVID-19 is an illness caused by the new coronavirus SARS-CoV-2, which presents a Clinical Picture that varies from asymptomatic infections to severe breathing problems. According to the World Health Organization (WHO), this disease is already present in all continents, with more than 562 million diagnosed cases and 6 million deaths up to 12/07/2022. Clinical reports and studies with COVID-19 patients have demonstrated significant changes on the levels of factor VIII, von Willebrand factor, and fibrinogen and D dimmers, especially in severe cases. Metabolic alterations, such as lipid dysfunctions, as the decrease on HDL levels feature a direct correlation with changes in hemostasis and are risk factors for the increase of the sternness of the illness. Once the risk of increasing severity and lethality of the illness are related to hemostatic changes, this present study aims to statistically analyze these alterations, in face of the advance on the severity of the disease. The biochemical alterations were analyzed through plasma laboratorial exams from patients infected by the SARS-CoV- 2 – collected on the Hospital Municipal Universitário de Taubate - and include metabolic markers as cholesterol/triglycerides and tests related to hemostasis. These results demonstrate several statistically significant correlations between these markers, following the evolution of the severity of COVID-19 and may contribute to a better understanding of the pathophysiology of this disease. In addition, these results may also contribute to other studies and in the development of new treatments for COVID-19.


A COVID-19 é uma doença causada pelo novo coronavírus SARS-CoV-2, que apresenta um quadro clínico que varia de infecções assintomáticas a quadros respiratórios graves. De acordo com a Organização Mundial de Saúde (OMS), essa doença já atingiu todos os continentes, com mais de 562 milhões de casos diagnosticados e mais de 6 milhões mortes, dados atualizados em 12/07/2022 segundo https://www.worldometers.info/coronavirus/. Relatos clínicos e estudos coorte com pacientes com COVID-19 demonstraram alterações significativas nos níveis de fator VIII, fator de von Willebrand, fibrinogênio e D-dímeros, principalmente em pacientes graves. Alterações metabólicas, como disfunções lipídicas, como a diminuição nos níveis do HDL apresentam correlação direta com alterações da hemostasia e são fatores de risco para o aumento da severidade da doença. Visto que o risco de aumento da gravidade e letalidade da COVID-19 está diretamente relacionado com alterações metabólicas, as quais têm estreita relação com alterações hemostáticas, o presente estudo objetivou estudar estatisticamente essas alterações, face ao avanço da gravidade desta doença. As alterações bioquímicas foram analisadas por exames laboratoriais de plasma de pacientes infectados pelo SARS- CoV-2, coletados no Hospital Municipal Universitário de Taubaté, e abrangem marcadores metabólicos, como colesterol/triglicerídeos e exames relacionados à hemostasia. Esses resultados demonstram diversas correlações estatisticamente significantes entres estes marcadores, acompanhando a evolução da severidade da COVID-19 e podem contribuir para uma melhor compreensão da fisiopatologia desta doença. Além disso, esses resultados podem colaborar em outros estudos e no desenvolvimento de novos tratamentos para a COVID-19.

RESUMO

Quinoa stands out as an excellent crop in the Cerrado region for cultivation in the off-season or irrigated winter season. Here, we tested the effects of different water regimes on the agronomic characteristics, physiology, and grain quality of different elite quinoa genotypes under field conditions. The experiment was conducted under field conditions at Embrapa Cerrados (Planaltina, DF, Brazil). The experimental design was in randomized blocks, in a split-plot scheme, with four replications. The plots were composed of 18 quinoa genotypes and modified BRS Piabiru (the currently used genotype), and the split-plots were divided into 4 different water regimes. The following variables were evaluated: productivity and productivity per unit of applied water (PUAA), plant height, flavonoids, anthocyanins, gas exchange, chlorophyll, leaf proline, and relative water content. Our results showed that water regimes between 309 and 389 mm can be recommended for quinoa in the Cerrado region. CPAC6 and CPAC13 presented the highest yield and PUAA under high and intermediate WRs, and hence were the most suitable for winter growth under irrigation. CPAC17 is most suitable for off-season growth under rainfed conditions, as it presented the highest PUAA under the low WRs (247 and 150). CPAC9 stood out in terms of accumulation of flavonoids and anthocyanins in all WRs. Physiological analyses revealed different responses of the genotypes to water restriction, together with symptoms of stress under lower water regimes. Our study reinforces the importance of detailed analyses of the relationship between productivity, physiology, and water use when choosing genotypes for planting and harvest in different seasons.

RESUMO

The selection of wheat genotypes according to their drought tolerance is essential to off-season cultivation. The objective of this work was to characterize wheat genotypes through yield and components, morphological characteristics under water stress, and irrigated water use efficiency in the Cerrado region in Brazil. Genotypes were planted during the winters of 2016 and 2017 since there is no precipitation during this season and water levels can be measured. They were then submitted to four water regimes: WR1, WR2, WR3, and WR4, representing 100 %, 83 %, 50 %, and 30 % of evapotranspiration replacement. The following variables were evaluated: peduncle length (PL), number of ears m-² (NE m-²), hectoliter weight (HW), thousand grain weight (TGW), drought resistance index (DRI), irrigated water use efficiency (IWUE) and yield. Most variables showed correlation with yield and can be a useful tool for breeding programs. PL and HW were best correlated with yield. BRS 264 (irrigated biotype) was productive in treatments receiving the greatest number of irrigation treatments. Given that WR1 registered the highest water level, it was not expected that the rainfed biotype (BR18) would show a higher yield than an irrigated biotype (BRS254). BRS404 (rainfed biotype) was the most productive under moderate stress treatment (WR3). Aliança (rainfed biotype) showed a higher yield under severe stress. Rainfed biotypes presented a higher DRI than the irrigated ones. These genotypes can be used as a reference in breeding programs under each water regime in which their performance was outstanding. None of the variables studied contributed to the selection of the most efficient wheat genotypes in the IWUE.

RESUMO

Snakebite accidents are a public health problem that affects the whole world, causing thousands of deaths and amputations each year. In Brazil, snakebite envenomations are caused mostly by snakes from the Bothrops genus. The local symptoms are characterized by pain, swelling, ecchymosis, and hemorrhages. Systemic disturbances can lead to necrosis and amputations. The present treatment consists of intravenous administration of bothropic antivenom, which is capable of reversing most of the systemic symptoms, while presenting limitations to treat the local effects, such as hemorrhage and to neutralize the snake venom serine protease (SVSP). In this context, we aimed to evaluate the activity of selective serine protease inhibitors (pepC and pepB) in combination with the bothropic antivenom in vivo. Further, we assessed their possible synergistic effect in the treatment of coagulopathy and hemorrhage induced by Bothrops jararaca venom. For this, we evaluated the in vivo activity in mouse models of local hemorrhage and a series of in vitro hemostasis assays. Our results showed that pepC and pepB, when combinated with the antivenom, increase its protective activity in vivo and decrease the hemostatic disturbances in vitro with high selectivity, possibly by inhibiting botropic proteases. These data suggest that the addition of serine protease inhibitor to the antivenom can improve its overall potential.

RESUMO

Trata-se de estudo realizado por demanda de um sindicato de trabalhadores metalúrgicos à Fundacentro, objetivando analisar as situações de violências vividas por trabalhadores adoecidos pelo trabalho em uma montadora de automóveis. Foram realizadas entrevistas com sindicalistas, visita à montadora, entrevistas individuais e coletivas com trabalhadores, validação dos dados. À luz da discussão sobre violências relacionadas ao trabalho e intensificação do trabalho, analisou-se sua relação com instrumentos de gestão. Com base na compreensão de gestão de Gaulejac e na perspectiva das evoluções conceituais sobre violência no trabalho, expressada por Soboll, entre outros, confirmaram-se práticas de exclusão e isolamento de trabalhadores adoecidos, humilhações e descaracterização das doenças relacionadas ao trabalho, deslegitimando e colocando os adoecidos sob suspeita. Instrumentos de gestão e elementos da cultura organizacional eram utilizados nestas práticas violentas caracterizando um modo de agir sistêmico que contribui para a cronificação de doenças e a geração de incapacidade, além de prejudicarem ações preventivas, tanto da própria empresa, como do Estado, pela ocultação de riscos e danos. Demandas dessa natureza são frequentes, evidenciando que a violência contra adoecidos pelo trabalho e o ocultamento de doenças do trabalho constituem sério problema social com impacto dramático nas vidas de trabalhadores e no sistema de saúde pública


This study was carried out by Fundacentro at the request of a metalworkers' union, aiming to characterize and analyze the situations of violence experienced by workers who had work-related injuries or illnesses, in an automobile assembly plant. Interviews with trade unionists, a visit to the automaker, individual and collective interviews with workers and validation of the data were carried out. It was based on the Gaulejac's management concept and the Soboll's violence at work concept. The exclusion and isolation of sick workers, humiliation, denial and de-characterization of work-related illnesses were confirmed, delegitimizing and placing the workers under suspicion. Management tools and elements of organizational culture were used in these violent practices, characterizing a systemic way of acting, which contributes to these diseases becoming chronic and generating incapacity, as well as impairing preventive actions, of both the company itself and the State, by concealment of risks and damages. Demands of this nature are frequent, evidencing that the violence against people with work-related illnesses and the concealment of such illnesses constitute an important social problem, with a dramatic impacts on the lives of workers and the public health system.

RESUMO

OBJECTIVE: Thyroxine-binding globulin (TBG) is the major human thyroid hormone transport protein, encoded by the SERPINA7 gene (Xq22.2). We aim to investigate the molecular basis of partial TBG deficiency (TBG-PD) in a female, by evaluating the X-chromosome inactivation pattern as well as the mutant protein structural modeling. DESIGN AND METHODS: Sequencing of the coding region of the SERPINA7 gene was performed in a female with a TBG-PD phenotype and her first-degree relatives. The proband presented with low serum levels of total T3 (TT3) and total T4 (TT4), serum TSH level of 5.4 µUI/mL (normal range, 0.35-5.5), and serum TBG level of 5.5 mg/L (normal range, 13.6-27.2). X-chromosome inactivation pattern was evaluated by methylation analysis of the androgen receptor gene (Xq11.2). Structural analysis of the SERPIN family was performed using Pymol and Areaimol, and PFSTATS for conservation analysis and family-wide investigation of equivalent positions in human homologs. Modeller was used for point mutation structural modeling. RESULTS: A novel missense SERPINA7 mutation (p.R35W; c.163C > T) was found in heterozygosity in the proband, and in hemizygosity in her affected siblings. The proband X-chromosome inactivation ratio was 20:80. The substitution of an arginine by a tryptophan is predicted to disrupt the protein surface and main electrostatic interactions. Tryptophans are extremely rare (0.1%) in this position. CONCLUSIONS: We report a new SERPINA7 variant associated with TBG-PD in three siblings. We named this variant TBG-Brasilia. The X-chromosome inactivation pattern may have accounted for the rare phenotypic expression in a female. The hydrophobic nature of the mutant is predicted to create an apolar patch at the surface, which results in protein aggregation and/or misfolding, potentially responsible for thyroid hormone transport defect.

RESUMO

Objetivo: Analisar a alteração legislativa do Estatuto do Idoso realizada pela Lei nº 13.466, de 12 de julho de 2017 ao rol de prioridades especiais concedidas a pessoas com mais de 80 anos. Metodologia: Tratou-se de estudo descritivo e analítico, de abordagem qualitativa e revisão bibliográfica sobre a legislação do idoso. Resultados: A análise da legislação permitiu constatar um conflito aparente entre normas legais referente a ordem de atendimento prioritário em saúde para as pessoas idosas. Conclusão: A lei posterior revogou a lei anterior sobre a fila de atendimento emergencial e que as pessoas de 80 anos, a partir da vigência da lei, tem prioridade no atendimento, mesmo que não apresentando risco grave para a saúde


Objective: To analyze the legislative amendment of the Statute of the elderly performed by law 13.466 of 2017/07/12, to the specials priorities granted to the elderly people over 80 years old. Methodology: It was a descriptive-analytical research, with qualitative approach and literature review of the legislation on the elderly population. Results: The analysis of the legislation showed an apparent conflict between legal norms regarding to priority order health care for the elderly population. Conclusion: The subsequent law revoked the previous law on the emergency service queue and the people with 80-year-olds, as of the time of the law, have priority in care, even if they do not present a serious risk to health


Objetivo: Analizar la modificación legislativa del Estatuto del Anciano realizada por la Ley nº 13.466, de 12 de julio de 2017, al las prioridades especiales concedidas a personas mayores de 80 años. Metodología: Se trató de estudio descriptivo y analítico, de abordaje cualitativo y revisión bibliográfica sobre la legislación del anciano. Resultados: El análisis de la legislación permitió constatar un conflicto aparente entre normas legales referentes al orden de atención prioritario en salud para las personas mayores de 80 años. Conclusión: La ley subsiguiente revocó la ley anterior sobre la cola del servicio de emergencia y las personas con 80 años de edad, en el momento de la ley, tienen prioridad en la atención, incluso si no presentan un riesgo grave para la salud

RESUMO

BACKGROUND: Bitterness perception seems to be related to an enhanced intake of dietary fat and to a tendency to the development of diseases such as obesity. However, the exact factors for this possible contribution still need to be better investigated. So, gustatory perception of the bitter taste is a promising area of study because of its importance regarding food choices and consequently feeding behavior. Therefore, this short review focused on recent papers reporting correlations between bitter taste, anthropometric variables, obesity and other chronic diseases, age, gender, ethnicity, and genetics. METHODS: A survey was performed in MEDLINE (PubMed) and Scielo from September 2015 to January 2017.Only review articles, observational studies and clinical trials published in English and Portuguese over the last15 years which met the objectives of the present study were considered. A total of 40 papers were evaluated. RESULTS: Two papers showed a positive correlation between bitter taste and obesity, one indicated that this correlation is influenced by the subject's age, one suggested a negative correlation, and two found no association. Age seems to be negatively correlated with the bitterness perceived, and female gender was associated with a stronger perception of bitterness. Genetics, mostly due to differences in TAS2R38 expression, influences sensitivity to the bitter taste, feeding behavior and also alcohol intake. Ethnicity, not only the subject's phenotypic or genotypic characteristics, seems to play a role in taste perception and nutritional diseases. CONCLUSIONS: Age, gender, genetics and ethnicity seem to play a role in bitterness perception. Data about associations between bitterness perception and anthropometrics are conflicting.

RESUMO

BACKGROUND: The effects of dietary levels of hop ß-acids on physical attributes, lipid oxidation and chemical composition of pork meat were evaluated. Thirty-two castrated male pigs obtained from a complete block design feeding experiment (6.23 ± 0.42 kg initial body weight (BW) to 20.45 ± 0.95 kg final BW) and fed diets supplemented with 0, 120, 240 or 360 mg kg-1 hop ß-acids during 35 days were slaughtered to sample longissimus dorsi muscle for meat analysis. RESULTS: No effects (P > 0.05) of dietary hop ß-acids were observed on meat physical attributes. Quadratic effects (P < 0.05) of hop ß-acids were observed on lipid and protein contents and on thiobarbituric acid-reactive substance (TBARS) values of meatballs, whose equations allowed the estimation of dietary hop ß-acid levels of 176, 169 and 181 mg kg-1 to provide up to 16.20% lipid reduction, 1.95% protein accretion and 23.31% TBARS reduction respectively. CONCLUSION: Dietary hop ß-acids fed to pigs might reduce lipid, increase protein and reduce lipid oxidation without affecting physical attributes of the pork meat. © 2017 Society of Chemical Industry.
