RESUMEN

The gaseous modulator hydrogen sulfide (H2S) is synthesized, among other routes, by the action of cystathionine-γ-lyase (CSE) and importantly participates in body fluid homeostasis. Therefore, the present study aimed to evaluate the participation of H2S in behavioral, renal and neuroendocrine homeostatic responses triggered by the acute consumption of a high Na+ diet. After habituation, adult male Wistar rats were randomly distributed and maintained for seven days on a control [CD (0.27% of Na+)] or hypersodic diet [HD (0.81% of Na+)]. CD and HD-fed animals were treated with DL-Propargylglycine (PAG, 25 mg/kg/day, ip) or vehicle (0.9% NaCl in equivalent volume) for the same period. At the end of the experiment, animals were euthanized for blood and tissue collection. We demonstrated that a short-term increase in dietary Na+ intake, in values that mimic the variations in human consumption (two times the recommended) significantly modified hydroelectrolytic homeostasis, with repercussions in the hypothalamic-neurohypophysial system and hypothalamic-pituitary-adrenal axis function. These findings were accompanied by the development of a clear inflammatory response in renal tubular cells and microvascular components. On the other hand, the inhibition of the endogenous production of H2S by CSE provided by PAG treatment prevented the inflammation induced by HD. In the kidney, PAG treatment induced the overexpression of inducible nitric oxide synthase in animals fed with HD. Taken together, these data suggest, therefore, that HD-induced H2S production plays an important proinflammatory role in the kidney, apparently counter regulating nitric oxide actions in renal tissue.

RESUMEN

Patients older than 75 years old with multiple myeloma (MM) have shorter survival and are usually treated differently from what features in clinical trials. In this study, the authors characterized the Portuguese population of MM patients above 75 years old, treated between 2009 and 2016. We compared the outcomes obtained with bortezomib-based protocols (BBP), thalidomide-based protocols (TBP), and chemotherapy (CT) using univariate and multivariate controlling for age, performance status, International Staging System score, renal impairment, and number of comorbidities. We retrieved data from 386 patients, treated in 12 hospitals. Three hundred thirty-one cases were analyzed: 119 patients treated with BBP, 65 with TBP, 147 with CT. Median age was 79 years; CT-treated patients were older, had a worse performance status, and have more comorbidities. The median follow-up was 25 months. The 2-year OS was 58% and the median OS was 29.5 months. Patients treated with BBP had more frequently very good partial response (VGPR) or better response, and the subgroup of more fit patients had a significantly longer progression-free survival (PFS) and OS. The most frequently grade 3-4 toxicities were hematologic, infectious, and neurologic and were significantly lower in TBP and CT groups vs BBP. The most common second line was CT, followed by lenalidomide. Patients treated with lenalidomide had a higher probability of VGPR or better and a superior 1-year PFS. Despite the limitations of a retrospective study, our cohort represents the reality of older patients with MM in a western country. The hazard of death or progression was higher for old, fit patients treated, in first line, with CT and with TBP compared with that of BBP.

RESUMEN

Chagas disease and sleeping sickness are neglected tropical diseases closely related to poverty, for which the development of plant-derived treatments has not been a promising prospect. Thus, we systematicaly review the preclinical in vivo evidence on the applicability of plant-based products in the treatment of Trypanosoma cruzi and Trypanosoma brucei infections. Characteristics such as disease models, treatments, toxicological safety and methodological bias were analysed. We recovered 66 full text articles from 16 countries investigating 91 plant species. The disease models and treatments were highly variable. Most studies used native (n = 36, 54·54%) or exotic (n = 30, 45·46%) plants with ethnodirected indication (n = 45, 68·18%) for trypanosomiasis treatment. Complete phytochemical screening and toxicity assays were reported in only 15 (22·73%) and 32 (48·49%) studies, respectively. The currently available preclinical evidence is at high risk of bias. The absence of or incomplete characterization of animal models, treatment protocols, and phytochemical/toxicity analyses impaired the internal validity of the individual studies. Contradictory results of a same plant species compromise the external validity of the evidence, making it difficult determine the effectiveness, safety and biotechnological potential of plant-derived products in the development of new anti-infective agents to treat T. cruzi and T. brucei infections.

RESUMEN

The large spectrum of hearing sensitivity observed in primates results from the impact of environmental and behavioral pressures to optimize sound perception and localization. Although evidence of positive selection in auditory genes has been detected in mammals including in Hominoids, selection has never been investigated in other primates. We analyzed 123 genes highly expressed in the inner ear of 27 primate species and tested to what extent positive selection may have shaped these genes in the order Primates tree. We combined both site and branch-site tests to obtain a comprehensive picture of the positively selected genes (PSGs) involved in hearing sensitivity, and drew a detailed description of the most affected branches in the tree. We chose a conservative approach, and thus focused on confounding factors potentially affecting PSG signals (alignment, GC-biased gene conversion, duplications, heterogeneous sequencing qualities). Using site tests, we showed that around 12% of these genes are PSGs, an α selection value consistent with average human genome estimates (10-15%). Using branch-site tests, we showed that the primate tree is heterogeneously affected by positive selection, with the black snub-nosed monkey, the bushbaby, and the orangutan, being the most impacted branches. A large proportion of these genes is inclined to shape hair cells and stereocilia, which are involved in the mechanotransduction process, known to influence frequency perception. Adaptive selection, and more specifically recurrent adaptive evolution, could have acted in parallel on a set of genes (ADGRV1, USH2A, PCDH15, PTPRQ, and ATP8A2) involved in stereocilia growth and the whole complex of bundle links connecting them, in species across different habitats, including high altitude and nocturnal environments.

RESUMEN

INTRODUCTION: Fragility fractures cause significant mortality and morbidity. Even though there are multiple guidelines for the management of fragility fractures, european countries still report treatment rates of less than 30%. Implementation of fracture liaison services can increase this percentage by 21%. Our goal is to describe the management of osteoporosis, in patients with hip fragility fracture treated in a portuguese hospital with no internal protocols in place. METHODS: A retrospective study was conducted. Patients treated surgically for hip fragility fracture in our hospital, during 2017, were included. Data until May 2020 was collected on osteoporosis recognition and pharmacological treatment prescription. RESULTS: A total of 102 patients were included, 87% female, with a mean age of 79.9±9.9 years at the time of the fracture. Pharmacological anti-osteoporotic treatment after the hip fragility fracture was prescribed in 35%. From those, 53% did not include bisphosphonates. General practice doctors were responsible for 44% of anti-osteoporotic prescriptions and "Osteoporosis" ICD10 codification in primary care was present in 10.7%. DISCUSSION/CONCLUSION: We found a gap in osteoporosis treatment after a hip fragility fracture, similar to literature reports when no fracture liaison service is in place. We believe that the lack of such protocols, the low rate of "osteoporosis" or "fragility fracture" mentioning at hospital discharge, together with the under recognition at primary care level, contribute to this reality. The implementation of new measures is crucial to improve prevention and management of fragility fractures.

RESUMEN

In the context of human evolution, the study of proteins may overcome the limitation of the high degradation of ancient DNA over time to provide biomolecular information useful for the phylogenetic reconstruction of hominid taxa. In this study, we used a shotgun proteomics approach to compare the tooth proteomes of extant human and non-human primates (gorilla, chimpanzee, orangutan and baboon) in order to search for a panel of peptides able to discriminate between taxa and further help reconstructing the evolutionary relationships of fossil primates. Among the 25 proteins shared by the five genera datasets, we found a combination of peptides with sequence variations allowing to differentiate the hominid taxa in the proteins AHSG, AMBN, APOA1, BGN, C9, COL11A2, COL22A1, COL3A1, DSPP, F2, LUM, OMD, PCOLCE and SERPINA1. The phylogenetic tree confirms the placement of the samples in the appropriate genus branches. Altogether, the results provide experimental evidence that a shotgun proteomics approach on dental tissue has the potential to detect taxonomic variation, which is promising for future investigations of uncharacterized and/or fossil hominid/hominin specimens. SIGNIFICANCE: A shotgun proteomics approach on human and non-human primate teeth allowed to identify peptides with taxonomic interest, highlighting the potential for future studies on hominid fossils.

RESUMEN

The antioxidant potential and phenolic profile of infusions prepared with cherry stems from different commercial brands were studied. The phenolic profile of each infusion was characterized by UHPLC-ESI-QTOF-MS and 44 phenolic compounds belonging to eight distinct classes (hydroxybenzoic acids, hydroxycinnamic acids, phenylpropanoic acids, flavan-3-ols, flavonols, flavanones, flavones and isoflavones) were tentatively identified. For the first time, salicylic acid was identified in cherry stem infusions. In cell-based assays, all the infusions tended to inhibit lipid peroxidation and presented no cytotoxicity. Significant differences (p < 0.05) were found between a sample sold in bulk (lower antioxidant activity by DPPH˙ inhibition, ferric reducing antioxidant power, and oxygen radical absorbance capacity assays; lower amounts of total phenolics and flavonoids and a different quantitative phenolic profile) and samples sold in packages. These, in turn, were very similar to each other and revealed a high antioxidant potential and a very rich phenolic profile. These results reflect not only the antioxidant potential of cherry stem infusions but also the need to globally harmonize the control and regulation of herbal products in order to ensure in the market products with high quality, safety and efficacy.

RESUMEN

We developed a new mutationally well-balanced 32 Y-STR multiplex (CombYplex) together with a machine learning (ML) program PredYMaLe to assess the impact of STR mutability on haplogourp prediction, while respecting forensic community criteria (high DC/HD). We designed CombYplex around two sub-panels M1 and M2 characterized by average and high-mutation STR panels. Using these two sub-panels, we tested how our program PredYmale reacts to mutability when considering basal branches and, moving down, terminal branches. We tested first the discrimination capacity of CombYplex on 996 human samples using various forensic and statistical parameters and showed that its resolution is sufficient to separate haplogroup classes. In parallel, PredYMaLe was designed and used to test whether a ML approach can predict haplogroup classes from Y-STR profiles. Applied to our kit, SVM and Random Forest classifiers perform very well (average 97 %), better than Neural Network (average 91 %) and Bayesian methods (< 90 %). We observe heterogeneity in haplogroup assignation accuracy among classes, with most haplogroups having high prediction scores (99-100 %) and two (E1b1b and G) having lower scores (67 %). The small sample sizes of these classes explain the high tendency to misclassify the Y-profiles of these haplogroups; results were measurably improved as soon as more training data were added. We provide evidence that our ML approach is a robust method to accurately predict haplogroups when it is combined with a sufficient number of markers, well-balanced mutation rate Y-STR panels, and large ML training sets. Further research on confounding factors (such as CNV-STR or gene conversion) and ideal STR panels in regard to the branches analysed can be developed to help classifiers further optimize prediction scores.

RESUMEN

OBJECTIVE: To calculate the frequency and evaluate the factors associated with low birth weight. METHODS: A retrospective study, with data from pregnant women who participated in the Programa de Atenção às Gestantes do Programa Einstein na Comunidade de Paraisópolis, between 2011 and 2014, and who returned for the postpartum evaluation of their newborns. Variables related to the pregnant woman, pregnancy, and newborn were evaluated. The outcome variable was low birth weight, defined as <2.5kg. The associations between the independent variables and low birth weight were assessed by χ2 and Mann-Whitney tests. Logistic regression models analyzed the combined effects of the independent variables on low birth weight. RESULTS: Data of 794 pregnant women and their newborns (52.1% males) were analyzed. The age of pregnant women varied from 13 to 44 years (median of 24 years), and the majority reported being married or living in cohabitation (74.7%), and having between 9 to 11 years of schooling (53.4%). The proportion of low birth weight was 7.6% (newborn mean weight of 3.2kg) and, in multivariate analysis, presence of twinning, age group of the pregnant women (showing protection for low birth weight between ages ≥18 years and <35 years), and cesarean section were associated with low birth weight. CONCLUSION: The proportion of low birth weight was 7.6% and twining, age of the pregnant woman, and cesarean delivery were associated with the occurrence of low birth weight.

RESUMEN

OBJECTIVE: To evaluate early bony changes in an animal model of Medication-Related Osteonecrosis of the Jaw (MRONJ) at the side of the local trauma and at the contralateral side, comparing with a control group. Bony changes were evaluated by Microcomputed Tomography (MicroCT) at three times points: at baseline (T0), after drug administration (T1) and after dental extraction (T2). DESIGN: Two groups were compared: the experimental group in which zoledronic acid (ZA) was administered (17 rats) and the control group (13 rats). Dental extractions of the lower left first molars were performed in all animals. The left side was considered as the supposed affected area in the ZA group, and the right side was considered as the unaffected area. In these areas, the following structural microtomographic bone parameters were calculated: Bone Mineral Density (BMD), Trabecular Thickness (Tb.Th), and Bone Volume Proportion (BV/TV). The comparison of quantitative bone parameters among the different sides and experimental phases of both studied groups were performed by ANOVA-factorial. RESULTS: None of the animals of the control group developed MRONJ. In the ZA group, 76% presented bone exposure. From T0 to T1, Tb.Th and BV/TV increased, and in T2, the mean values were higher in ZA group than in the control group. BMD increased throughout the different phases of both groups. CONCLUSIONS: Structural bony changes occurred in the ZA group at both mandibular sides before the dental extraction (T1). Tb.Th and BV/TV should be further investigated as potential early bone markers of MRONJ.

RESUMEN

A Doença de Parkinson (DP) é uma doença degenerativa e progressiva do sistema nervoso central, caracterizada por sintomas motores, alterações musculoesqueléticas e posturais que podem ser influenciadas por um processo de organização sensorial anormal. A eletromiografia (EMG) é uma ferramenta de avaliação não invasiva importante para análise do recrutamento da musculatura postural. A terapia vibratória surge como uma opção promissora na estimulação somatossensorial desta população. Objetivo: Avaliar os efeitos da terapia vibratória no recrutamento da musculatura postural em pacientes com DP. Métodos: Foram analisados os músculos longuíssimo lombar (LL) e trapézio ascendente (TA) por EMG. Foi realizada a aplicação de um protocolo de 8 semanas (24 atendimentos) de terapia vibratória em 10 indivíduos com DP, com avaliação e reavaliação por análise eletromiográfica da contração isométrica voluntária (CIV). Resultados: A terapia vibratória não mostrou resultados significativos na ativação da musculatura postural na DP, pela avaliação por EMG, sendo na comparação pré e pós-tratamento TAD (p = 0,655), TAE (p = 0,655), LLD (p = 0,848) e LLE (p = 0,565). Conclusão: Não houve resultados significativos na EMG após intervenção com terapia vibratória em indivíduos com DP, o que pode ser devido principalmente ao tamanho amostral. Sugere-se a realização de novos estudos com maior tamanho amostral para comprovar a eficiência da terapia vibratória nesta população.


Parkinson Disease (PD) is a degenerative and progressive disease of the central nervous system, characterized by motor symptoms, musculoskeletal and postural disturbance, which may be influenced by an abnormal sensory organization process. Electromyography (EMG) is an important non-invasive assessment tool for postural muscle recruitment analysis. Vibratory therapy appears as promising option to somatosensory stimulation in this population. Objective: To evaluate the effects of vibratory therapy on the recruitment of postural muscles in patients with PD. Methods: Longissimus lumborum (LL) and the upper trapezius (UT) muscles were analyzed by EMG. A protocol of 8 weeks (24 attendances) of vibratory therapy was applied in 10 individuals with PD, with evaluation and revaluation performed by EMG analysis of voluntary isometric contraction (VIC). Results: Vibratory therapy did not show significant results in the activation of the postural muscles in the PD, by the EMG evaluation, being the TAD (p = 0.655), APR (p = 0.655), LLD (p = 0.848) and LLE (p = 0.565). Conclusion: We did not observe significant results in the EMG after intervention with vibratory therapy in individuals with PD, which may be mainly due to the sample size. It is suggested to carry out new studies with a larger sample size to prove the efficiency of the vibratory therapy in this population.

RESUMO Objetivo Calcular a frequência e avaliar os fatores associados ao baixo peso ao nascer. Métodos Estudo retrospectivo, com os dados das gestantes que participaram do Programa de Atenção às Gestantes do Programa Einstein na Comunidade de Paraisópolis, entre 2011 e 2014, e que retornaram para realizar a avaliação de seus recém-nascidos após o parto. Foram avaliadas as variáveis relacionadas à gestante, à gestação e ao recém-nascido. A variável desfecho foi o baixo peso ao nascer, definido como <2,5kg. As associações entre as variáveis independentes e o baixo peso ao nascer foram avaliadas por meio dos testes χ2e de Mann-Whitney. Modelos de regressão logística analisaram os efeitos combinados das variáveis independentes no baixo peso ao nascer. Resultados Foram analisados os dados de 794 gestantes e de seus recém-nascidos (52,1% do sexo masculino). A idade das gestantes variou de 13 a 44 anos (mediana de 24 anos) e a maioria referia ser casada ou estar em união estável (74,7%) e possuir entre 9 a 11 anos de estudo (53,4%). A proporção de baixo peso ao nascer foi de 7,6% (peso médio do recém-nascido de 3,2kg) e, na análise múltipla, a presença de gemelaridade, a faixa etária das gestantes (mostrando proteção para o baixo peso ao nascer nas idades ≥18 anos e <35 anos), e o parto cesárea se associaram com o baixo peso ao nascer. Conclusão A proporção de baixo peso ao nascer foi de 7,6% e gemelaridade, idade da gestante e parto cesárea se associaram com a ocorrência de baixo peso ao nascer.

RESUMEN

RESUMO Introdução O Relatório Flexner é considerado o ponto de partida para a discussão do ensino da medicina no século XX. Após amplas discussões, em 2001, o Ministério da Educação homologa as Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina (DCN). Tais diretrizes objetivam a formação de um médico generalista, humanista, reflexivo, crítico, que atue como promotor da saúde integral do ser humano. A Pediatria é a área da medicina onde a promoção da saúde integral é de extrema importância, pois a criança é o adulto do futuro. Objetivo Discutir as questões: O que se espera do médico geral, em relação à Pediatria, no século XXI? E a questão dela derivada: Mudanças nas diretrizes para o ensino de Pediatria são necessárias a partir das DCN? Métodos Ensaio reflexivo com base em dois documentos: Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina (DCN) e Diretrizes para o Ensino de Pediatria (DEP) propostas por Eduardo Marcondes. Discussão Este artigo discorre a respeito das percepções de Marcondes acerca do ensino de Pediatria, correlacionando-as com as DCN e discutindo aspectos importantes na formação do médico, tais como: promoção, prevenção, proteção e reabilitação em saúde e educação médica em Pediatria. Considerações finais As Diretrizes para o Ensino de Pediatria propostas por Marcondes em 1993 parecem se manter extremamente atuais no contexto brasileiro do século XXI, ressalvando-se apenas diferenças de mortalidade e morbidade infantil.


ABSTRACT Introduction The Flexner report is considered the starting point for the discussion on the teaching of medicine in the 20th century. Following broad debate in 2001, the Ministry of Education approved the National Curricular Guidelines (DCNs) for the Undergraduate Course in Medicine. These guidelines are aimed at forming general, humanistic, reflective and critical physicians, to act as promoters of comprehensive human health. Pediatrics is a medical area where the promotion of comprehensive health is extremely important, since a child is a future adult. Objective Discuss issues like ‘What is expected from a pediatric general practitioner, in the 21st century?’ And the follow-on question: ‘Is it necessary to make changes in pediatric training through the National Curricular Guidelines?’ Methods Reflexive study based on two documents: the National Curricular Guidelines for the Undergraduate Course in Medicine and the Guidelines for Teaching Pediatrics proposed by Eduardo Marcondes. Discussion This article presents Marcondes’ views on the teaching of pediatrics in relation to the DCNs. It also discusses important aspects of the doctor´s training, such as health promotion, prevention, protection and rehabilitation and pediatric medical training. Final considerations The Guidelines for Teaching Pediatrics suggested by Marcondes in 1993 remain highly relevant to 21st century Brazil, with exception only to differences in infant mortality and morbidity rates.

Método: trata-se de um estudo com abordagem qualitativa da construção do jogo educativo com trabalhadores do CME, no período de agosto-dezembro 2012, com frequência semanal, totalizando 20 encontros. A técnica de análise das respostas obtidas foi a de conteúdo. Resultados: caracterizou-se três categorias temáticas. Os discursos evidenciaram melhorias na interação da equipe a partir das pausas no trabalho, a educação permanente a partir da metodologia ativa de ensinoaprendizagem e mudanças do papel do trabalhador para lugar de sujeito significante do seu trabalho. Conclusão: percebese que o jogo constitui-se como importante ferramenta para a promoção da QVT na equipe de enfermagem do CME, trabalhando de forma interativa e lúdica com aspectos organizacionais complexos dentro do contexto de análise. Considera-se que tais estratégias venham a ganhar mais espaço nas instituições de saúde para que tais elementos possam ser trabalhados em conjunto com gestores e equipe, a fim de promover a efetiva QVT e uma prestação de serviços em saúde cada vez mais humanizada...


Objective: To describe and analyze the development of an educational game as a strategy to promote the quality of work life (QWL) for the nursing staff from the Material and Sterilization Center (MSC) of a university hospital. Method: This is a study with a qualitative approach to the production of an educational game with the MSC workers, from August-December 2012, with a weekly frequency, totaling 20 meetings. The technique of analysis of responses was content analysis. Results: Three thematic categories were characterized.

RESUMEN

Pelger-Huët anomaly (PHA) is a benign inherited condition characterized by hyposegmentation of the neutrophil's nucleus and excessive chromatin clumping. An acquired neutrophil dysplasia similar to PHA has been described in hematological diseases and in some clinical conditions. It has been known as acquired or pseudo PHA. Although some hypotheses have been proposed to explain this phenomenon, the mechanism of nuclear change is still unclear. Only the laboratory and clinical data combined will yield a better understanding on the need for follow-up and management of patients in the appropriate cases. In addition, a possible cause of pseudo PHA must always be investigated to add insights to the full understanding of this abnormality. Whether this neutrophil phenomenon has clinical implications remains to be elucidated. It is clear that only a small number of patients under drugs (immunosuppressive and others) may present these neutrophil abnormalities. Most of them do not show this phenomenon and we are unable to explain the different responses in drug users. Whether these patients display a predisposition for developing bone marrow or other diseases in the future, it is a very intriguing matter and only a follow-up will solve this question.

RESUMEN

OBJETIVO: Verificar a prevalência de diabetes mellitus referido e fatores associados em idosos residentes em Campina Grande-PB. METODOLOGIA: Trata-se de estudo transversal, de base populacional e domiciliar, com indivíduos de 60 anos de idade ou mais, de ambos os sexos. O diabetes mellitus referido foi considerado variável dependente para fins de análise e de estudo das possíveis associações. As variáveis independentes avaliadas foram: grupo etário, situação conjugal, nível socioeconômico, estado nutricional, prática de atividade física regular, tabagismo e ingestão de bebida alcoólica. Para identificar os fatores associados ao diabetes mellitus referido, foram realizadas análises de regressão univariada e multivariada, por meio do SPSS 17.0. RESULTADOS: Foram avaliados 806 idosos (69,1% mulheres), com média etária de 72,4 anos (DP=8,76). A prevalência de diabetes mellitus referido foi de 14,7%. Tanto entre homens como entre mulheres, constatou-se maior prevalência do diabetes mellitus referido no grupo etário de 60 a 69 anos (50% e 48,2%, respectivamente). O diabetes mellitus referido esteve associado às variáveis sobrepeso/obesidade (IC95%: 1,028-4,248; p=0,042) e ingestão de bebidas alcoólicas (IC95%: 1,107-3,092; p=0,019) entre as idosas. Entre os homens, houve associação com a doença referida apenas com a ingestão de bebidas alcoólicas no passado (IC95%: 1,082-13,085; p=0,037). CONCLUSÃO: Os resultados deste estudo sugerem influência do estado nutricional e da ingestão de bebidas alcoólicas (atual ou passada) sobre o diabetes mellitus referido em idosos.

OBJECTIVE: To determine the prevalence of self-reported diabetes mellitus and associated factors in elderly living in the city Campina Grande-PB, Brazil. METHODOLOGY: Cross-sectional, population- and home-based study with individuals aged 60 years or older of both sexes. Self-reported diabetes mellitus was considered dependent variable for purposes of analysis and study of possible associations. Independent variables were: age group, marital status, socioeconomic level, nutritional status, regular practice of physical activities, smoking and alcohol consumption. To identify factors associated with self-reported diabetes mellitus, univariate and multivariate regression analyses were performed, using SPSS 17.0. RESULTS: Overall, 806 elderly patients (69.1% women) with mean age of 72.4 years (SD=8.76) were assessed. Prevalence of self-reported diabetes mellitus was 14.7%. Higher prevalence of self-reported diabetes mellitus in the age group of 60-69 years (50.0% and 48.2%, respectively) was observed both among men and women. Self-reported diabetes mellitus was associated with overweight/obesity (95% CI: 1.028-4.248, p=0.042) and alcohol consumption (95% CI: 1.107-3.092, p=0.019) among women. Among men, there was an association with the disease only for the past consumption of alcoholic beverages (95% CI: 1.082-13.085, p=0.037). CONCLUSION: The results suggest an influence of nutritional status and alcohol consumption (current or past) on diabetes mellitus in the elderly. Knowing the modifiable factors that influence this disease is critical to support the planning of actions for promotion, prevention and early diagnosis of this condition. .
