Genome-based analyses to learn from and about Paenibacillus sonchi genomovar Riograndensis SBR5T.

Paenibacillus sonchi genomovar Riograndensis SBR5T is a plant growth-promoting rhizobacterium (PGPR) isolated in the Brazilian state of Rio Grande do Sul from the rhizosphere of Triticum aestivum. It fixes nitrogen, produces siderophores as well as the phytohormone indole-3-acetic acid, solubilizes phosphate and displays antagonist activity against Listeria monocytogenes and Pectobacterium carotovorum. Comprehensive omics analysis and the development of genetic tools are key to characterizing and engineering such non-model microorganisms. Therefore, the complete genome of SBR5T was sequenced, and shown to encode 6,705 proteins, 87 tRNAs, and 27 rRNAs and it enabled a landscape transcriptome analysis that unveiled conserved transcriptional and translational patterns and characterized operon structures and riboswitches. The pangenome of P. sonchi species is open with a stable core pangenome. At the same time, the analysis of genes coding for nitrogenases revealed that the trait of nitrogen fixation is sparse within the Paenibacillaceae family and the presence of Fe-only nitrogenase in the P. sonchi group was exclusive to SBR5T. The development of genetic tools for SBR5T enabled genetic transformation, plasmid construction for constitutive and inducible gene expression, and gene repression using the CRISPRi system. Altogether, the work with P. sonchi can guide the study of non-model bacteria with economic potential.

Efficacy of Oral Furosemide Test for Primary Aldosteronism Diagnosis.

Context: Confirmatory tests represent a fundamental step in primary aldosteronism (PA) diagnosis, but they are laborious and often require a hospital environment due to the risks involved. Objective: To evaluate the efficacy of oral furosemide as a new confirmatory test for PA diagnosis. Methods: We prospectively evaluated the diagnostic performance of 80 mg of oral furosemide in 64 patients with PA and 22 with primary hypertension (controls). Direct renin concentration (DRC) was measured before, and 2 hours and 3 hours after the oral furosemide. In addition, the oral furosemide test was compared with 2 other confirmatory tests: the furosemide upright test (FUT) and saline infusion test (SIT) or captopril challenge test (CCT) in all patients with PA. Results: The cut-off of 7.6 µU/mL for DRC at 2 hours after oral furosemide had a sensitivity of 92%, specificity of 82%, and accuracy of 90% for PA diagnosis. In 5 out of 6 controls with low-renin hypertension, which might represent a PA spectrum, renin remained suppressed. Excluding these 6 controls with low-renin hypertension, the DRC cut-off of 10 µU/mL at 2 hours after oral furosemide had a sensitivity of 95.3%, specificity of 93.7% and accuracy of 95% for PA diagnosis. DRC after 3 hours of oral furosemide did not improve diagnostic performance. Using the cut-off of 10 µU/mL, the oral furosemide test and the FUT were concordant in 62 out of 64 (97%) patients with PA. Only 4 out of 64 cases with PA (6.4%) ended the oral furosemide test with potassium <3.5 mEq/L. Hypotension was not evidenced in any patient with PA during the test. Conclusion: The oral furosemide test was safe, well-tolerated and represents an effective strategy for PA investigation.

Factors associated with diet quality among Brazilian individuals with cardiovascular diseases.

BACKGROUND: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors. METHODS: This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant. RESULTS: In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence. CONCLUSIONS: A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

Metabolic engineering of thermophilic Bacillus methanolicus for riboflavin overproduction from methanol.

The growing need of next generation feedstocks for biotechnology spurs an intensification of research on the utilization of methanol as carbon and energy source for biotechnological processes. In this paper, we introduced the methanol-based overproduction of riboflavin into metabolically engineered Bacillus methanolicus MGA3. First, we showed that B. methanolicus naturally produces small amounts of riboflavin. Then, we created B. methanolicus strains overexpressing either homologous or heterologous gene clusters encoding the riboflavin biosynthesis pathway, resulting in riboflavin overproduction. Our results revealed that the supplementation of growth media with sublethal levels of chloramphenicol contributes to a higher plasmid-based riboflavin production titre, presumably due to an increase in plasmid copy number and thus biosynthetic gene dosage. Based on this, we proved that riboflavin production can be increased by exchanging a low copy number plasmid with a high copy number plasmid leading to a final riboflavin titre of about 523 mg L-1 in methanol fed-batch fermentation. The findings of this study showcase the potential of B. methanolicus as a promising host for methanol-based overproduction of extracellular riboflavin and serve as basis for metabolic engineering of next generations of riboflavin overproducing strains.

Reflections on research ethics in a public health emergency: Experiences of Brazilian women affected by Zika.

In Brazil, the epicenter of the Zika crisis, brown, black, and indigenous poor women living in municipalities with scarce resources were disproportionally affected. The gendered consequences of the epidemic exposed how intersectional lenses are central to understand the impact of public health emergencies in the lives of women and girls. The demand for Zika-affected children and women to be research participants is relevant for an ethical analysis of participant protection procedures during a crisis. We investigated how women experienced research participation by analyzing their narratives. Two-year-long longitudinal qualitative study in Brazilian sites located in the epidemic's epicenter was performed using mixed methods: ethnography with women from two distinct states and individual semi-structured interviews with five women in different Zika-affected states, four of which were community leaders. All women in the study were mothers or grandmothers of Zika-affected children. Thematic analysis was used for data evaluation. Women perceived being pressured to participate in research and a lack of benefit sharing. Structural determinants of gender inequality, such as its effect on power distribution, were found to impact research participant protection. Formal procedures for research protocols approvals were insufficient in protecting participants because these instruments were unable to account for structural aspects. Communitarian mobilization, through WhatsApp groups, was found to be an important mechanism to create conditions to challenge oppressive structures. Strengthening public health, effective community-based participation in research planning and implantation of ethical strategies that promotes gender equality can have transformative effect on unequal power structures and promote participant protection.

Intra-individual Variability of Serum Aldosterone and Implications for Primary Aldosteronism Screening.

CONTEXT: Primary aldosteronism (PA) screening relies on an elevated aldosterone to renin ratio with a minimum aldosterone level, which varies from 10 to 15 ng/dL (277-415.5 pmol/L) using immunoassay. OBJECTIVE: To evaluate intra-individual coefficient of variation (CV) of aldosterone and aldosterone to direct renin concentration ratio (A/DRC) and its impact on PA screening. METHODS: A total of 671 aldosterone and DRC measurements were performed by the same chemiluminescence assays in a large cohort of 216 patients with confirmed PA and at least 2 screenings. RESULTS: The median intra-individual CV of aldosterone and A/DRC was 26.8% and 26.7%. Almost 40% of the patients had at least one aldosterone level <15 ng/dL, 19.9% had at least 2 aldosterone levels <15 ng/dL, and 16.2% had mean aldosterone levels <15 ng/dL. A lower cutoff of 10 ng/dL was associated with false negative rates for PA screening of 14.3% for a single aldosterone measurement, 4.6% for 2 aldosterone measurements, and only 2.3% for mean aldosterone levels. Considering the minimum aldosterone, true positive rate of aldosterone thresholds was 85.7% for 10 ng/dL and 61.6% for 15 ng/dL. An A/DRC >2 ng/dL/µIU/mL had a true positive rate for PA diagnosis of 94.4% and 98.4% when based on 1 or 2 assessments, respectively. CV of aldosterone and A/DRC were not affected by sex, use of interfering antihypertensive medications, PA lateralization, hypokalemia, age, and number of hormone measurements. CONCLUSION: Aldosterone concentrations had a high CV in PA patients, which results in an elevated rate of false negatives in a single screening for PA. Therefore, PA screening should be based on at least 2 screenings with concomitant aldosterone and renin measurements.

Autonomia do jovem com síndrome de down: concepções de mães e filhos1 / Autonomy of young people with down syndrome: conceptions of mothers and children

RESUMO O objetivo deste artigo foi analisar as concepções de mães e filhos em relação à autonomia de jovens com Síndrome de Down. Nesse sentido, participaram deste estudo 20 mães e 20 jovens com Síndrome de Down. Foi realizado um estudo qualitativo, por meio de entrevistas semiestruturadas, que foram gravadas, transcritas e posteriormente analisadas. Os resultados do estudo mostraram que a perspectiva das mães com relação à autonomia diz respeito à realização das atividades cotidianas em casa, mas, ao sair desse ambiente, eles demonstram medo, não permitindo que os filhos ampliem essa autonomia para outros ambientes. Com relação ao jovem com Síndrome de Down, é possível perceber que, mesmo não entendendo a sua condição genética e o que venha a ser de fato autonomia, eles demonstram o desejo de terem uma vida como qualquer outro jovem, que estuda, namora, trabalha, sai de casa sozinho. Assim sendo, é preciso a implementação de programas voltados à capacitação de profissionais, família e jovens com SD no auxílio à autonomia.

ABSTRACT The objective of this article was to analyze the conceptions of mothers and children in relation to the autonomy of young people with Down Syndrome. In this sense, 20 mothers and 20 young people with Down Syndrome participated in this study. A qualitative study was carried out through semi-structured interviews, which were recorded, transcribed and subsequently analyzed. The results of the study showed that the perspective of mothers regarding autonomy concerns carrying out daily activities at home, but when leaving this environment, they show fear, not allowing their children to extend this autonomy to other environments. With regard to young people with Down Syndrome, it is possible to notice that even though they do not understand their genetic condition and what autonomy actually means, they demonstrate the desire to have a life like any other young person, who studies, dates, works, leaves home alone. Thus, it is necessary to implement programs aimed at training professionals, families and young people with DS in helping autonomy.

Descarte de medicamentos domiciliares: uma análise de amostra obtida de uma ação de extensão realizada no município de Seropédica-Rj / Disposal of home medicines: a sample analysis obtained from an extension action carried out in the municipality of Seropédica-Rj / Descarga de medicamentos domiciarios: análisis de muestra obtenido de una acción de extensión realizada en el municipio de la Seropedic-Rj

O Brasil é um dos países que mais consomem medicamentos no mundo, em contrapartida não há uma legislação que regulamente o descarte de medicamentos domiciliares, sendo a maioria deles descartados incorretamente no lixo comum ou esgoto, contaminando o meio ambiente e trazendo prejuízos ambientais, sociais e econômicos. Ao analisar o material foi observado que 95,98% eram sólidos, 2,58 líquidos, 1,51% semissólidos e 0,24% outros. Já em relação às classes terapêuticas 27,25% eram medicamentos de ação cardiovascular, 15,30% de ação gastrointestinal, 15,07% de antimicrobianos, 14,44% de ação no SNC, 10,71% anti-inflamatórios, 5,49% analgésicos e antipiréticos, 3,52% antialérgicos, 3,31% de ação no trato respiratório, 2,83% hormônios e 2,09% outros. E o prejuízo econômico decorrente da perda dos medicamentos foi de aproximadamente R$ 9470,00. Diante do exposto, podemos concluir que o uso irracional de medicamentos, a não adesão terapêutica, a falta de fracionamento, as estratégias do marketing farmacêutico, as prescrições irracionais, a venda sem prescrição e a falta de educação sanitária da população a respeito dos medicamentos levam a um consumo indiscriminado dos mesmos, o que corrobora para o acúmulo nas residências e o descarte incorreto.

Brazil is one of the countries that consume most medicines in the world, in contrast there is no legislation that regulates the disposal of home medicines, most of them being disposed of incorrectly in common garbage or sewage, contaminating the environment and bringing environmental, social and economic damages. When analyzing the material, it was observed that 95.98% were solid, 2.58 liquids, 1.51% semi-solid and 0.24% others. With regard to the therapeutic classes, 27.25% were medicines with a cardiovascular action, 15.30% with a gastrointestinal action, 15.07% with antimicrobials, 14.44% with an CNS action, 10.71% with anti-inflammatories, 5.49% with analgesics and antipyretics, 3.52% with antiallergies, 3.31% with an action on the respiratory tract, 2.83% with hormones and 2.09% others. And the economic loss resulting from the loss of the medicines was approximately R$ 9470.00. In the light of the above, we can conclude that the irrational use of medicines, the non-adherence to treatment, the lack of fractionation, the strategies of pharmaceutical marketing, the irrational prescriptions, the non-prescription sale and the lack of health education of the population regarding the medicines lead to an indiscriminate consumption of the medicines, which corroborates for the accumulation in the residences and the incorrect disposal.

Brasil es uno de los países que más consumen medicinas en el mundo, en contraste, no existe legislación que regule la eliminación de medicinas domésticas, la mayoría de las cuales son descartadas incorrectamente en desechos o aguas residuales comunes, contaminando el medio ambiente y ocasionando pérdidas ambientales, sociales y económicas. Al analizar el material se observó que el 95,98% eran sólidos, 2,58 líquidos, 1,51% semisólidos y 0,24% otros. En cuanto a las clases terapéuticas, el 27,25% fueron medicamentos de acción cardiovascular, el 15,30% de acción gastrointestinal, el 15,07% antimicrobianos, el 14,44% de acción del SNC, el 10,71% antiinflamatorios, el 5,49% analgésicos y antipiréticos, el 3,52% 3,31% de acción en el tracto respiratorio, 2,83% de hormonas y 2,09% de otras. Y la pérdida económica resultante de la pérdida de los medicamentos fue de aproximadamente R$ 9470,00. A la luz de lo que antecede, podemos concluir que el uso irracional de los medicamentos, la no adhesión a la terapia, la falta de fraccionamiento, las estrategias de comercialización farmacéutica, las prescripciones irracionales, la venta sin receta y la falta de educación en la salud de la población sobre los medicamentos conducen a su consumo indiscriminado, lo que corrobora la acumulación en los hogares y la eliminación incorrecta.

Solidariedade, cidadania e justiça social: percepções de atores sociais sobre as respostas públicas à COVID-19 / Solidarity, citizenship and social justice: perceptions of social actors about public responses to COVID-19

Resumo Trata-se de uma análise qualitativa das percepções de atores sociais sobre as respostas públicas durante a pandemia de COVID-19. Foram conduzidas entrevistas semiestruturadas com 11 representantes da sociedade civil indicados por lideranças de movimentos sociais. Para garantir a análise de uma diversidade de vozes, também realizamos a sistematização de artigos de opinião de autoria de organizações humanitárias e lideranças da sociedade civil, publicados em jornais de grande circulação. Nossa análise se inspirou nos princípios éticos da justiça social, solidariedade e cidadania. Utilizamos da análise temática, na qual dois temas principais emergiram: 1) as populações desproporcionalmente afetadas seguem invisibilizadas para cuidados e proteções; 2) há um projeto intencional de aniquilamento das populações consideradas indesejáveis. Para cuidados e mitigação dos efeitos durante emergências sanitárias, os movimentos comunitários devem ser incorporados como parte essencial das respostas. Cuidado, solidariedade e participação cidadã são centrais para a construção de respostas para proteção em saúde dentro do marco da justiça social. As respostas para transformação do futuro pós-pandêmico se localizam nas iniciativas da sociedade civil e de lideranças comunitárias dentro dos territórios.

Abstract This qualitative study aimed to analyze the social actors' perceptions of public responses during the COVID-19 pandemic. We conducted semi-structured interviews with eleven civil society representatives and social movement leaders. We also performed triangulation based on the systematization of opinion papers authored by humanitarian organizations and civil society leaders and published in large-circulation newspapers. Our analysis was inspired by the ethical principles of social justice, solidarity, and citizenship. Two main themes emerged from the thematic analysis: 1) disproportionately affected populations remain invisible to care and protection; 2) there is an intentional project to annihilate "undesirable" populations. Community movements must be incorporated as an essential part of the responses to provide care and protection and mitigate the effects during health emergencies. Care, solidarity, and social participation are central to building health protection responses within the framework of social justice. The responses to transforming the future in the aftermath of the pandemic will occur through the initiatives of civil society and community leaders within the territories.

Ética do uso de escores prognósticos em unidade de terapia intensiva: revisão integrativa / Ethics in the use of prognostic scores in intensive care units: an integrative review / Ética del uso de puntajes pronósticos en una unidad de cuidados intensivos: una revisión integradora

Resumo O enfrentamento da covid-19 suscitou uma série de problemas na área da saúde, em razão do aumento da demanda de cuidados intensivos. Para solucionar a crise causada pela escassez de recursos de alta complexidade, a tomada de decisão tem se norteado por escores prognósticos, porém esse processo inclui uma dimensão moral, ainda que esta seja menos evidente. Mediante revisão integrativa, este artigo buscou refletir sobre a razoabilidade da utilização de indicadores de gravidade para definir a alocação de recursos escassos na saúde. Observou-se que o trabalho realizado em situações de escassez de recursos provoca sobrecarga moral, convergindo para busca por soluções padronizadas e objetivas, como a utilização de escores prognósticos. Conclui-se que seu uso isolado e indiscriminado não é eticamente aceitável e merece avaliação cautelosa, mesmo em situações emergenciais, como a da covid-19.

Abstract Facing COVID-19 caused many problems in the healthcare field, due to the rise in the intensive care demand. To solve this crisis, caused by the scarcity of resources of high complexity, decision-making has been guided by prognostic scores; however, this process includes a moral dimension, although less evident. With na integrative review, this article sought to reflect on the reasonability of using severity indicators to define the allocation of the scarce resources in healthcare. We observed that the work carried out on resource scarcity situations causes moral overload, converging to the search for standard and objective solutions, such as the use of prognostic scores. We conclude that their isolated and indiscriminate use is not ethically acceptable and deserves cautious evaluation, even in emergency situations, such as COVID-19.

Resumen La lucha contra el Covid-19 implicó una serie de problemas en el área de la salud, debido al aumento de la demanda de cuidados intensivos. Para solucionar la crisis provocada por la escasez de recursos de alta complejidad, la toma de decisiones estuvo orientada por puntuaciones pronósticas, pero este proceso incluye una dimensión moral aún menos evidente. A partir de una revisión integradora, este artículo buscó reflexionar sobre la razonabilidad de utilizar indicadores de gravedad para definir la asignación de recursos escasos en salud. El trabajo realizado en situaciones de escasez de recursos genera sobrecarga moral, llevando a la búsqueda de soluciones estandarizadas y objetivas, como el uso de puntuaciones de pronóstico. Se concluye que su uso aislado e indiscriminado no es éticamente aceptable y merece una cuidadosa evaluación, incluso en situaciones de emergencia, como la del Covid-19.

Improvement of 2,2'-Azobis(2-Methylpropionamidine) Dihydrochloride-Induced Hepatic Redox Imbalance in Swiss Mice and HepG2 Cells by Rutin.

Redox imbalance can lead to irreversible damages to biological functions. In this context, rutin stands out for its antioxidant potential. The objective of this study was to evaluate the acute and chronic effect of rutin on the hepatic redox imbalance. The study was performed according to three different protocols. First, healthy male Swiss mice were divided into two groups: control and rutin, the second of which received chronic oral supplementation of rutin (10 mg/kg). The second involved evaluation of the generation of reactive oxygen species (ROS) by HepG2 cells, incubated or not with rutin (20 and 40 µg/mL) for 3 h. The final protocol involved assessment of the acute effect of rutin (10 mg/kg) in mice with oxidative stress induced by 2,2'-azobis(2-methylpropionamidine) dihydrochloride (ABAP). After the in vivo treatments, the livers were collected to analyze the oxidative damage by thiol, and the antioxidant defense by catalase, superoxide dismutase, and glutathione peroxidase. In the HepG2 cells, the following probes were employed to assess the ROS production: dichlorofluorescein, MitoSOX, dihydroethidium, and Amplex Red. Rutin administered chronically improved the antioxidant defense in healthy animals, and when administered acutely both inhibited the increased production of ROS in HepG2 cells and improved the redox imbalance parameters in mice with induced oxidative stress. This study suggests rutin as a protective agent for restoration of hepatic redox homeostasis in redox injury induced by ABAP in Swiss mice and HelpG2 cells.

From Brown Seaweed to a Sustainable Microbial Feedstock for the Production of Riboflavin.

The increasing global demand for food and energy production encourages the development of new production strategies focused on sustainability. Often, microbial bioprocesses rely on food or feed competitive feedstocks; hence, there is a trending need for green substrates. Here, we have proven the potential of brown seaweed biomass as microbial feedstock on account of its content of mannitol and the glucose polymer laminarin. Our host, Corynebacterium glutamicum, was engineered to enable access to mannitol as a carbon source through the heterologous expression of the mannitol-specific phosphotransferase system and the mannitol-1-phosphate-5-dehydrogenase from Bacillus subtilis. Overproduction of riboflavin was coupled with mannitol and glucose consumption via constitutive overexpression of the biosynthetic riboflavin operon ribGCAH from C. glutamicum. Brown seaweed extract and brown seaweed hydrolysate from Laminaria hyperborea, containing mannitol and glucose, were used as a carbon source for flask and bioreactor fermentations. In a seaweed-based fed-batch fermentation, the riboflavin final titer, yield, and volumetric productivity values of 1,291.2 mg L-1, 66.1 mg g-1, and 17.2 mg L-1 h-1, respectively, were achieved.

Unravelling Formaldehyde Metabolism in Bacteria: Road towards Synthetic Methylotrophy.

Formaldehyde metabolism is prevalent in all organisms, where the accumulation of formaldehyde can be prevented through the activity of dissimilation pathways. Furthermore, formaldehyde assimilatory pathways play a fundamental role in many methylotrophs, which are microorganisms able to build biomass and obtain energy from single- and multicarbon compounds with no carbon-carbon bonds. Here, we describe how formaldehyde is formed in the environment, the mechanisms of its toxicity to the cells, and the cell's strategies to circumvent it. While their importance is unquestionable for cell survival in formaldehyde rich environments, we present examples of how the modification of native formaldehyde dissimilation pathways in nonmethylotrophic bacteria can be applied to redirect carbon flux toward heterologous, synthetic formaldehyde assimilation pathways introduced into their metabolism. Attempts to engineer methylotrophy into nonmethylotrophic hosts have gained interest in the past decade, with only limited successes leading to the creation of autonomous synthetic methylotrophy. Here, we discuss how native formaldehyde assimilation pathways can additionally be employed as a premise to achieving synthetic methylotrophy. Lastly, we discuss how emerging knowledge on regulation of formaldehyde metabolism can contribute to creating synthetic regulatory circuits applied in metabolic engineering strategies.
