Estimation of the availability of iron in the school meals of Municipal Centers for Early Childhood Education of a capital city in northeastern Brazil.

The final stage of Fe deficiency is Fe deficiency anaemia, with repercussions for human health, especially in children under 5 years of age. Studies conducted in Brazilian public daycare centres show high prevalence of anaemia. The present study aims to evaluate the availability of Fe in the meals of the Municipal Centers of Early Childhood Education in Maceió. The experimental design comprises selection of algorithms, menu evaluation, calculation of the estimates, comparison between the estimates obtained and the recommendations, and analysis of correlation between meal constituents, and of the concordance between the absorbable Fe estimates. Four algorithms were selected and a monthly menu consisting of 22 d. The correlation analysis showed a moderate positive correlation to animal tissue (AT) v. non-heme iron (r = 0·42; P = 0·04), and negative to AT v. Ca (r = -0·54; P = 0·09) and Ca v. phytates (r = -0·46, P = 0·03). Estimates of absorbable Fe ranged from 0·23 to 0·44 mg/d. The amount of Fe available, unlike the total amount of Fe offered, does not meet the nutritional recommendations on most school days. The Bland-Altman analysis indicated that the Monsen and Balinfty and Rickard et al. showed greater agreement. The results confirm the need to adopt strategies to increase the availability of Fe in school meals.

Effects of SARS-CoV-2 infection on health and functional capacity in institutionalized older adults.

OBJECTIVE: To assess the effect of SARS-CoV-2 infection on the health conditions and functional capacity of older adults living in long-term care units in Maceió City - Alagoas State. METHODS: A prospective cohort was conducted with institutionalized older adults of both sexes. Older adults were assessed for clinical conditions (diagnosis of chronic diseases and biochemical tests), functional capacity, and nutritional status. All assessments were repeated on two occasions, maintaining a 6-month interval between them. RESULTS: The sample was composed of 289 older adults. Of the total, 98 (33.9%) were positive for COVID-19 and eight died (2.8%). Men were more likely to have COVID-19 (OR = 3.50; p < 0.01). It was observed that the disease contributed to increasing the frequency of dependent older adults after six months (OR = 1.38; p-interaction < 0.01). It was also observed that after six months of positive diagnosis for COVID-19, there was greater weight loss (p < 0.01), reduced BMI (p < 0.01), increased mean SBP (p = 0.04), and DBP (p = 0.03). CONCLUSION: Effects of COVID-19 in institutionalized older adults go beyond acute complications and compromise blood pressure control, functional capacity, and favor weight loss.

25-hydroxyvitamin D insufficiency and inflammation increase cardiovascular risk in older people.

PURPOSE: The objective of this study was to identify an association between serum levels of 25(OH) D, inflammation and cardiovascular disease risk in older adults. METHODS: This was a cross-sectional study, with older adults of both sexes, investigating variables on lifestyle, anthropometric assessments (weight, height, waist circumference, BMI), and systemic arterial hypertension (systolic blood pressure, SBP, and diastolic blood pressure DBP), serum levels of 25(OH)D, serum high-sensitive C-reactive protein (hs-CRP), serum lipid profile and fasting blood glucose. Cardiovascular disease risk was assessed using the global risk score for cardiovascular events, the Framingham criteria. RESULTS: The sample consisted of 124 participants, 50.8% of whom were at high risk for cardiovascular events. Older adults with 25(OH)D insufficiency presented higher levels of blood sugar (p < 0.01), LDL-c (p = 0.03) SBP (p < 0.01) and hs-CRP (p < 0.01). When grouped by serum concentrations hs-CRP, it was observed that higher hs-CRP levels were associated with higher blood glucose (p = 0.02), SBP (p = 0.04) and lower HDL-c concentrations (p = 0.02). It was also observed that 25(OH)D insufficiency increased the chance of a high risk for cardiovascular events by 2.8 times (OR = 2.80; p = 0.01), which with high hs-CRP concentrations increased to 4.75 times (OR = 4.75; p < 0.01). CONCLUSION: Low concentrations of 25(OH)D and the presence of inflammation in older adults are associated with a high risk for cardiovascular diseases.

Frequency and factors associated with sarcopenia prediction in adult and elderly patients hospitalized for COVID-19.

Patients with COVID-19 may develop symptoms that interfere with food intake. Systemic inflammatory response associated with physical inactivity and/or immobilization during hospital stay can induce weight and muscle loss leading to sarcopenia and worsening the clinical condition of these patients. The present study identifies the frequency and factors associated with sarcopenia prediction in adult and elderly patients hospitalized for COVID-19. It is a cohort-nested cross-sectional study on adult and elderly patients admitted to wards and intensive care units (ICUs) of 8 hospitals in a northeastern Brazilian state. The study was conducted from June 2020 to June 2021. Sociodemographic, economic, lifestyle, and current and past clinical history variables were collected. Sarcopenia prediction was determined by the Strength, Assistance in walking, Rise from a chair, Climb stairs, and Falls (SARC-F) questionnaire compiled in the Remote-Malnutrition APP (R-MAPP). Patients were diagnosed with sarcopenia when the final score ≥ 4 points. The study included 214 patients with a mean age of 61.76 ± 16.91 years, of which 52.3 % were female and 57.5 % elderly. Sarcopenia prevailed in 40.7 % of the sample. Univariate analysis showed greater probability of sarcopenia in elderly individuals, nonpractitioners of physical activities, hypertensive patients, diabetic patients, and those hospitalized in the ICU. In the multivariate model, the type of hospital admission remained associated with sarcopenia prediction, where patients admitted to the ICU were 1.43 (95 % CI: 1.04; 1.97) more likely to have sarcopenia than those undergoing clinical treatment. Sarcopenia prediction was not associated with patient outcome (discharge, transfer, or death) (p = 0.332). The study highlighted an important percentage of sarcopenia prediction in patients with COVID-19, especially those admitted to the ICU. Additional investigations should be carried out to better understand and develop early diagnostic strategies to assist in the management of sarcopenic patients with COVID-19.

Association between being underweight and excess body weight before SARS coronavirus type 2 infection and clinical outcomes of coronavirus disease 2019: Multicenter study.

OBJECTIVES: The present study aimed to identify associations between extremes in body weight status (underweight and excess body weight) before a COVID-19 diagnosis and clinical outcomes in patients infected with SARS coronavirus type 2. METHODS: A multicenter cohort study was conducted in eight different states in northeastern Brazil. Demographic, clinical (previous diagnosis of comorbidities), and anthropometric (self-reported weight and height) data about individuals who tested positive for COVID-19 were collected. Outcomes included hospitalization, mechanical ventilation, and death. Multivariable logistic regression models, adjusted based on age, sex and previous comorbidities, were used to assess the effects of extremes in body weight status on clinical outcomes. RESULTS: A total of 1308 individuals were assessed (33.6% were elderly individuals). The univariable analyses showed that only hospitalization was more often observed among underweight (3.2% versus 1.2%) and overweight (68.1% versus 63.3%) individuals. In turn, cardiovascular diseases were more often observed in all clinical outcomes (hospitalization: 19.7% versus 4.8%; mechanical ventilation: 19.9% versus 13.5%; death: 21.8% versus 14.1%). Based on the multivariable analysis, body weight status was not associated with risk of hospitalization (underweight: odds ratio [OR]: 1.10; 95% confidence interval [CI] 95%, 0.50-2.41 and excess body weight: OR: 0.81; 95 CI, 0.57-1.14), mechanical ventilation (underweight: OR: 0.92; 95% CI, 0.52-1.62 and excess weight: OR: 0.90; 95% CI, 0.67-1.19), and death (underweight: OR: 0.61; 95% CI, 0.31-1.20 and excess body weight: OR 0.88; 95% CI, 0.63-1.23). CONCLUSIONS: Being underweight and excess body weight were not independently associated with clinical outcomes in patients with COVID-19 in the herein analyzed cohort. This finding indicates that the association between these variables may be confounded by both age and comorbidities.

Selenium concentrations in elderly people with Alzheimer's disease: a cross-sectional study with control group.

OBJECTIVE: To investigate possible differences in plasma and erythrocyte concentrations of selenium among elderly with and without a diagnosis of Alzheimer's disease (AD). METHODS: Cross-sectional study, performed with an elderly group with Alzheimer's disease, diagnosed by a geriatric doctor, and compared to an elderly group without the disease, equaling gender, education, and age. Atomic absorption spectrophotometry determined plasma and erythrocyte concentrations of total selenium (Set). RESULTS: The mean age was 74.41±7.1 years in the Alzheimer's disease group and 71.46±5.1 years among the control group. The Alzheimer's disease group presented lower plasma concentrations (mean of 45.29±14.51 µg/dL vs. 55.14±14.01 µg/dL; p=0.004), and erythrocyte Set (median of 56.36 µg/L vs. 76.96 µg/L; p<0.001). The logistic regression model indicated an association between erythrocyte Set concentrations and diagnosis of Alzheimer's disease (p=0.028). CONCLUSION: Elderly with Alzheimer's disease present lower selenium concentrations in the evaluated organic compartments.

[Effects of physical exercise on cardiovascular risk and quality of life in hypertensive elderly people]. / Efeitos do exercício físico sobre o risco cardiovascular e qualidade de vida em idosos hipertensos.

The scope of this article is to evaluate the effects of a mixed protocol of physical exercises on cardiovascular risk (CVR), quality of life and the presence of depressive symptoms in elderly hypertensive patients. It involved a longitudinal, prospective and quasi-experimental study with 48 elderly individuals. A physical exercise protocol was developed for 16 weeks according to American College of Sports Medicine, and anthropometric variables (weight, height, body mass index and waist circumference), as well as biochemical variables (total cholesterol, LDL-c, HDL-c; triglycerides) were evaluated. The mean age was 66.5±4.8 years. The frequent CVR factors were dyslipidemia (58.3%) and sedentary lifestyle (45.8%). After intervention, there was a reduction in mean values of total and LDL-cholesterol and increased HDL-cholesterol levels. The CVR and global risk score decreased significantly. The frequency of depressive symptoms decreased from 25% to 4.2%. An improvement was observed in SF-36 physical, health and vitality domains. The mixed protocol of physical exercises constituted a possible low cost and effective alternative in the improvement of the lipid profile and the quality of life related to the health of the elderly who participated in this research.

O objetivo deste artigo é avaliar efeitos de um protocolo misto de exercícios físicos sobre o risco cardiovascular (RCV), qualidade de vida e presença de sintomas depressivos em idosos hipertensos. Estudo longitudinal, prospectivo e quase-experimental com 48 idosos. Desenvolveu-se um protocolo de exercícios físicos durante 16 semanas, segundo American College Sports of Medicine e foram realizadas avaliações antropométricas (peso, estatura, índice de massa corporal e circunferência da cintura) e bioquímicas (colesterol total, LDL-c, HDL-c; triglicerídeos). A média de idade foi de 66,5±4,8 anos. Os fatores de RCV frequentes foram dislipidemia (58,3%) e sedentarismo (45,8%). Após intervenção houve redução dos valores médios de colesterol total e LDL-colesterol e aumentaram níveis de HDL-colesterol. O RCV e a pontuação do escore de risco global diminuíram significativamente. A frequência de sintomas depressivos reduziu de 25% para 4,2%. Observou-se melhora nos domínios do SF-36: físico, saúde e vitalidade. O protocolo misto de exercícios físicos constituiu-se em alternativa possível, de baixo custo e eficaz na melhora do perfil lipídico e da qualidade de vida relacionada à saúde dos idosos desta pesquisa.

PRE-OPERATIVE FASTING: WHY ABBREVIATE?

INTRODUCTION: Considering the practice of preoperative fasting based on observations on the gastric emptying delay after induction and the time of this fast is closely linked to organic response to trauma, arise the question about preoperative fasting period necessary to minimize such response and support the professional with clinical and scientific evidence. AIM: To review the aspects related to the abbreviation of preoperative fasting from the metabolic point of view, physiology of gastric emptying, its clinical benefits and the currently recommendations. METHOD: Literature review was based on articles and guidelines published in English and Portuguese, without restriction of time until January 2017, in PubMed, SciELO and Cochrane with the descriptors: surgery, preoperative fasting, carbohydrate. From the universe consulted, 31 articles were selected. RESULTS: The literature suggests that the abbreviation of fasting with beverage added carbohydrates until 2 h before surgery, can bring benefits on glycemic and functional parameters, reduces hospitalization, and does not present aspiration risk of healthy patients undergoing elective surgery. Another nutrient that has been added to the carbohydrate solution and has shown promising results is glutamine. CONCLUSION: The abbreviation of preoperative fasting with enriched beverage with carbohydrates or carbohydrate and glutamine seems to be effective in the care of the surgical patient, optimizing the recovery from of postoperative period.

Associação entre risco de sarcopenia e complicações clínicas da covid-19 em pessoas idosas hospitalizadas: estudo de coorte multicêntrico / Association between the risk of sarcopenia and clinical complications of covid-19 in hospitalized older adults: a multicenter cohort study

Resumo Objetivo Verificar se o risco de sarcopenia em pessoas idosas diagnosticadas com covid-19 associa-se com demanda por cuidados intensivos, ventilação mecânica e óbito. Método Estudo multicêntrico do tipo coorte, que incluiu pessoas idosas (≥65 anos) com diagnóstico laboratorial confirmado de covid-19. Foram coletados dados relacionados às características sociodemográficas, clínicas e nutricionais. O risco de sarcopenia foi avaliado pelo questionário Sarcopenia Risk Screening. As variáveis de desfecho foram: necessidade de terapia intensiva, ventilação mecânica e óbito. Foram realizadas regressões logísticas para verificar a associação dos desfechos clínicos e o risco de sarcopenia, com as seguintes variáveis de ajuste: idade, sexo, renda familiar, atividade física, hipertensão, diabetes, doença cardiovascular doença pulmonar obstrutiva crônica e índice de massa corporal. Resultados Foram incluídas no estudo 264 pessoas idosas com covid-19, com média de idade de 71,7 (±8,2) anos. Cento e quarenta e oito pessoas idosas (56,1%) tinham risco de sarcopenia. Hipertensão, diabetes e doença cardiovascular foram as principais comorbidades identificadas nas pessoas idosas, respectivamente, 75,4%, 45,5% e 28,4%. O risco de sarcopenia nas pessoas idosas hospitalizadas com covid-19 aumentou em mais de 2 vezes as chances de internamento na UTI (OR: 2,71 [1,57;4,68], p<0,001), em cerca de 5 vezes as chances de ventilação mecânica (OR: 5,19 [2,75;9,78], p<0,001) e em mais de 3 vezes as chances de óbito (OR: 4,05 [2,05;7,98], p<0,001). Conclusão Em pessoas idosas hospitalizadas com covid-19, a pré-existência do risco de sarcopenia foi preditor de desfechos clínicos desfavoráveis.

Abstract Objective To investigate whether the risk of sarcopenia in older adults diagnosed with covid-19 is associated with the need for intensive care, mechanical ventilation, and mortality. Method A multicenter cohort study was conducted, including older adults (≥65 years) with laboratory-confirmed covid-19 diagnosis. Data related to sociodemographic, clinical, and nutritional characteristics were collected. The risk of sarcopenia was assessed using the Sarcopenia Risk Screening questionnaire. Outcome variables included the need for intensive care, mechanical ventilation, and mortality. Logistic regressions were performed to assess the association between clinical outcomes and the risk of sarcopenia, adjusting for the following variables: age, gender, family income, physical activity, hypertension, diabetes, cardiovascular disease, chronic obstructive pulmonary disease, and body mass index. Results The study included 264 older adults with covid-19, with an average age of 71.7 (±8.2) years. One hundred and forty-eight older adults (56.1%) were at risk of sarcopenia. Hypertension, diabetes, and cardiovascular disease were the most common comorbidities identified in older adults, at 75.4%, 45.5%, and 28.4%, respectively. The presence of sarcopenia risk in hospitalized older adults with covid-19 increased the odds of ICU admission by more than 2-fold (OR: 2.71 [1.57; 4.68], p<0.001), nearly 5-fold for mechanical ventilation (OR: 5.19 [2.75; 9.78], p<0.001), and over 3-fold for mortality (OR: 4.05 [2.05; 7.98], p<0.001). Conclusion In hospitalized older adults with covid-19, pre-existing risk of sarcopenia was a predictor of unfavorable clinical outcomes.

Perda de peso como preditor de mau prognóstico em pacientes hospitalizados com COVID-19 / Weight loss as a predictor of poor prognosis in patients hospitalized for COVID-19

Objetivo: Avaliar a relação entre a perda de peso com marcadores de mau prognóstico em pacientes hospitalizados com COVID-19 no estado de Pernambuco. Métodos: Estudo multicêntrico, transversal, acoplado a algumas variáveis de análise prospectiva envolvendo 71 indivíduos com COVID-19 admitidos para internação em 8 hospitais públicos de Recife, no Estado de Pernambuco. Foram incluídos indivíduos de ambos os sexos, com idade ≥ 20 anos, hospitalizados, no período de junho de 2020 a junho de 2021. Foram coletados dados sociodemográficos, clínicos, nutricionais e marcadores prognósticos. Resultados: A média de idade foi 54,6±15,6 anos, sendo 54,9% dos indivíduos do sexo masculino. Verificou-se que 26,8% dos pacientes eram diabéticos e 52,1% eram hipertensos. O perfil antropométrico indicou 56,3% de excesso de peso e 5,6% de baixo peso. Observou-se rastreio positivo para sarcopenia em 16,9%. A mediana da perda de peso foi 3,1% (0,0-6,6%), sendo uma perda > 5% evidenciada em 29,6% da amostra. Verificou-se que a perda de peso foi mais frequente nos homens (16 (41,0%) vs. 5 (15,6%); p = 0,020) e que as variáveis demográficas, clínicas e nutricionais não se associaram à redução do peso corporal. Não houve associação estatística entre a perda de peso e as variáveis prognósticas (p NS). Conclusão: embora o estudo não tenha demonstrado associação entre a perda de peso e variáveis prognósticas, esta deve ser considerada na avaliação do paciente com COVID-19, devendo ser investigada e tratada como uma importante medida de promoção à saúde.

Objective: To evaluate the relationship between weight loss and markers of poor prognosis in patients hospitalized with COVID-19 in the state of Pernambuco. Methods: A multicenter, cross-sectional study coupled with prospective analysis variables involving 71 individuals with COVID-19 admitted for hospitalization in 8 public hospitals in Recife, in the State of Pernambuco. Individuals of both sexes, aged ≥ 20 years, hospitalized from June 2020 to June 2021 were included. Sociodemographic, clinical, and nutritional data and prognostic markers were collected. Results: The average age was 54.6±15.6 years, with 54.9% of individuals being male. It was found that 26.8% of the patients were diabetic and 52.1% were hypertensive. The anthropometric profile indicated that 56.3% were overweight and 5.6% were underweight. Positive screening for sarcopenia was observed in 16.9%. The median weight loss was 3.1% (0.0-6.6%), with a loss > 5% evident in 29.6% of the sample. It was found that weight loss was more frequent in men (16 (41.0%) vs. 5 (15.6%); p = 0.020) and that demographic, clinical, and nutritional variables were not associated with body weight loss. There was no statistical association between weight loss and prognostic variables (p NS). Conclusion: Although the study did not demonstrate an association between weight loss and prognostic variables, this should be considered when assessing patients with COVID-19 and should be investigated and treated as an essential health promotion measure.

Associação entre indicadores da capacidade funcional e do estado nutricional em idosos da comunidade: uma nova abordagem / Association between functional capacity and nutritional status indicators in elderly community: a new approach

Resumo Introdução Alterações na composição corporal do idoso podem ser rapidamente identificadas por profissionais de saúde na Atenção Básica, reduzindo o impacto sobre a saúde, o estado nutricional e a capacidade funcional. Objetivo Identificar relações entre massa e força muscular com o estado nutricional e a capacidade funcional em idosos da comunidade. Método Estudo transversal, envolvendo 323 idosos. A avaliação da composição corporal foi realizada por absorciometria (DEXA) e antropometria. A capacidade funcional foi avaliada pelas Atividades Instrumentais de Vida Diária, pela velocidade da marcha (VM) e Time Up and Go (TUG). Resultados Nesta amostra, o índice de massa magra (IMM) se mostrou associado aos indicadores do estado nutricional (IMC, CP e CC), além de ter apresentado importante correlação com a força de preensão palmar (FPP). A FPP esteve relacionada à VM e ao TUG. A análise de regressão identificou associação entre o IMC e o IMM (p<0,001), bem como entre a VM e a FPP (p=0,003). Conclusão A FPP se apresentou como importante indicador da capacidade funcional e se mostrou correlacionada com o IMM. Consequentemente, o IMM está associado aos indicadores do estado nutricional. Logo, na impossibilidade de avaliação do IMM, recomendamos a avaliação da FPP, CP e IMC como preditores de comprometimento do estado nutricional e da incapacidade funcional do idoso.

Abstract Background Changes in the body composition of the elderly can be quickly identified by health professionals in primary care, reducing the impact on health, nutritional status, and functional capacity. Objective To look for links between muscle mass and strength, nutritional status, and functional capacity in community-dwelling elderly. Method A cross-sectional study involving 323 elderly people was carried out. Body composition assessment was performed by absorptiometry (DEXA) and anthropometry. Functional capacity was assessed by Instrumental Activities of Daily Living and by gait speed (VM) and Time Up and Go (TUG). Results In this sample, the lean mass index (LMI) was associated with indicators of nutritional status (BMI, NC, and WC), in addition to having shown an important correlation with handgrip strength (HGS). HGS was associated with VM and TUG. Regression analysis identified an association between BMI and LMI (p < 0.001) and between GS and HGS (p = 0.003). Conclusion HGS was an important indicator of functional capacity and correlated with LMI. Consequently, the LMI is associated with indicators of nutritional status. Therefore, when it is impossible to assess the LMI, we recommend the assessment of HGS, NC and BMI as predictors of compromised nutritional status and functional disability in the elderly.

Sarcopenia and risk of malnutrition as risk factors for complications from COVID-19 / Sarcopenia e risco de desnutrição como fatores de risco para complicações da COVID-19

Purpose: This study aimed to associate nutritional and sarcopenia risk with clinical outcomes in elderly patients with COVID-19. Methods: This is a longitudinal retrospective cohort study. Hospitalized elderly individuals diagnosed with COVID-19 were included in the study. Nutritional risk was assessed using the Malnutrition Universal Screening Tool (MUST), and Sarcopenia risk was assessed using the SARC-F. Associations were assessed through multivariable logistic models. Results: In total, 127 patients (mean age: 71.25 ±8.06 years) were followed up until the clinical outcome. Sarcopenia risk was diagnosed in 63.8% of the sample, whereas nutritional risk was observed in 72%. Hospitalization in the intensive care unit (ICU) was required in 48.8% of the sample, 38.6% required mechanical ventilation, and 32.3% died. Elderly individuals with sarcopenia risk were more likely to be hospitalized in ICUs (OR: 5.62; 95%CI: 2.2-14.3), require mechanical ventilation (OR: 4.0; 95% CI: 1.5-10.2), and die (OR: 5.06; 95% CI: 1.7-14.2). The risk of malnutrition assessed through MUST was an important risk factor for death (OR = 30.15; 95% CI: 3.6-245.8; p<0.01). Conclusion: Sarcopenia risk was a risk factor for death, hospitalization in ICU, and mechanical ventilation, while nutritional risk was a risk factor for death (AU).

Objetivo: Este estudo teve como objetivo associar o risco nutricional e de sarcopenia com desfechos clínicos em pacientes idosos com COVID-19. Métodos: Trata-se de um estudo de coorte retrospectivo longitudinal. Idosos hospitalizados com diagnóstico de COVID-19 foram incluídos no estudo. O risco nutricional foi avaliado usando o Malnutrition Universal Screening Tool (MUST) e o risco de sarcopenia foi avaliado usando o SARC-F. As associações foram avaliadas por modelos logísticos multivariados. Resultados: No total, 127 pacientes (média de idade: 71,25 ±8,06 anos) foram acompanhados até o desfecho clínico. Risco de sarcopenia foi diagnosticado em 63,8% da amostra, enquanto risco nutricional foi observado em 72% deles. Além disso, 48,8% da amostra necessitou de internação em unidade de terapia intensiva (UTI), 38,6% necessitaram ventilação mecânica e 32,3% foram a óbito. Idosos com risco de sarcopenia tiveram maior chance de internação em UTI (OR: 5,62; IC 95%: 2,2-14,3), necessidade de ventilação mecânica (OR: 4,0; IC 95%: 1,5-10,2) e óbito (OR: 5,06; IC 95%: 1,7-14,2). O risco de desnutrição avaliado pelo MUST foi um importante fator de risco para óbito (OR = 30,15; IC 95%: 3,6-245,8; p<0,01). Conclusão: O risco de sarcopenia foi fator de risco para óbito, internação em UTI e ventilação mecânica, enquanto o risco nutricional foi fator de risco para óbito (AU).

Influência do estado nutricional e do diagnóstico de diabetes na evolução clínica de pacientes hospitalizados com COVID-19 / Influence of nutritional status and diagnosis of diabetes in the clinicalevolution of hospitalized patients with COVID-19

Introducción: A fines de 2019 en la ciudad de Wuhan, China, se describieron los primeros casos de síndrome respiratorio causado por la enfermedad del coronavirus 2019 (COVID-19). La obesidad o desnutrición, asociadas a comorbilidades como la hipertensión y la diabetes, pueden incrementar significativamente el riesgo de hospitalización y muerte en estos pacientes.

Selenium concentrations in elderly people with Alzheimer's disease: a cross-sectional study with control group / Concentraciones de selenio en ancianos con enfermedad de Alzheimer: un estudio trasversal con equipo-control / Concentrações de selênio em idosos com doença de Alzheimer: um estudo transversal com grupocontrole

ABSTRACT Objective: To investigate possible differences in plasma and erythrocyte concentrations of selenium among elderly with and without a diagnosis of Alzheimer's disease (AD). Methods: Cross-sectional study, performed with an elderly group with Alzheimer's disease, diagnosed by a geriatric doctor, and compared to an elderly group without the disease, equaling gender, education, and age. Atomic absorption spectrophotometry determined plasma and erythrocyte concentrations of total selenium (Set). Results: The mean age was 74.41±7.1 years in the Alzheimer's disease group and 71.46±5.1 years among the control group. The Alzheimer's disease group presented lower plasma concentrations (mean of 45.29±14.51 µg/dL vs. 55.14±14.01 µg/dL; p=0.004), and erythrocyte Set (median of 56.36 µg/L vs. 76.96 µg/L; p<0.001). The logistic regression model indicated an association between erythrocyte Set concentrations and diagnosis of Alzheimer's disease (p=0.028). Conclusion: Elderly with Alzheimer's disease present lower selenium concentrations in the evaluated organic compartments.

Selenium and Zinc Status in Chronic Myofascial Pain: Serum and Erythrocyte Concentrations and Food Intake.

INTRODUCTION: Nutritional disorders have been reported to be important causal factors that can intensify or cause a painful response in individuals with chronic musculoskeletal pain. AIM: To assess the habitual intake of and the serum and erythrocyte levels of selenium and zinc in patients with chronic myofascial pain. MATERIALS AND METHODS: A case-control study of 31 patients with chronic myofascial pain (group I) and 31 subjects without pain (group II). Dietary record in five days for assessing food intake were used. The serum and erythrocyte concentrations of selenium and zinc were analyzed using an atomic absorption spectrophotometry. Pain intensity was assessed using a visual analog scale. RESULTS: The group of patients with chronic myofascial pain, compared with the control group, showed a lower erythrocyte concentration of selenium (79.46 ± 19.79 µg/L vs. 90.80 ± 23.12 µg/L; p = 0.041) and zinc (30.56 ± 7.74 µgZn/gHb vs. 38.48 ± 14.86 µgZn/gHb, respectively; p = 0.004). In this study, a compromised food intake of zinc was observed in the majority of the subjects in both groups. The selenium intake was considered to be safe in 80% of the subjects in both groups; however, the likelihood of inadequate intake of this mineral was twice as high in group I (49.5% vs. 24.4%, respectively). In the logistic regression analysis, the erythrocyte concentration of zinc was associated with the presence of pain. In each additional 1 mg of Zn2+ per gram of hemoglobin, a reduction of 12.5% was observed in the risk of the individual having chronic myofascial pain (B = -0.133; adjusted OR = 0.875, 95% CI = 0.803 to 0.954, Wald = 9.187, standard error = 0.044, p = 0.002). Physical inactivity and obesity were noted more commonly in group I compared with the control group. CONCLUSION: In this study, patients with chronic myofascial pain showed lower intracellular stores of zinc and selenium and inadequate food intake of these nutrients.

Efeitos do exercício físico sobre o risco cardiovascular e qualidade de vida em idosos hipertensos / Effects of physical exercise on cardiovascular risk and quality of life in hypertensive elderly people

Resumo O objetivo deste artigo é avaliar efeitos de um protocolo misto de exercícios físicos sobre o risco cardiovascular (RCV), qualidade de vida e presença de sintomas depressivos em idosos hipertensos. Estudo longitudinal, prospectivo e quase-experimental com 48 idosos. Desenvolveu-se um protocolo de exercícios físicos durante 16 semanas, segundo American College Sports of Medicine e foram realizadas avaliações antropométricas (peso, estatura, índice de massa corporal e circunferência da cintura) e bioquímicas (colesterol total, LDL-c, HDL-c; triglicerídeos). A média de idade foi de 66,5±4,8 anos. Os fatores de RCV frequentes foram dislipidemia (58,3%) e sedentarismo (45,8%). Após intervenção houve redução dos valores médios de colesterol total e LDL-colesterol e aumentaram níveis de HDL-colesterol. O RCV e a pontuação do escore de risco global diminuíram significativamente. A frequência de sintomas depressivos reduziu de 25% para 4,2%. Observou-se melhora nos domínios do SF-36: físico, saúde e vitalidade. O protocolo misto de exercícios físicos constituiu-se em alternativa possível, de baixo custo e eficaz na melhora do perfil lipídico e da qualidade de vida relacionada à saúde dos idosos desta pesquisa.

Abstract The scope of this article is to evaluate the effects of a mixed protocol of physical exercises on cardiovascular risk (CVR), quality of life and the presence of depressive symptoms in elderly hypertensive patients. It involved a longitudinal, prospective and quasi-experimental study with 48 elderly individuals. A physical exercise protocol was developed for 16 weeks according to American College of Sports Medicine, and anthropometric variables (weight, height, body mass index and waist circumference), as well as biochemical variables (total cholesterol, LDL-c, HDL-c; triglycerides) were evaluated. The mean age was 66.5±4.8 years. The frequent CVR factors were dyslipidemia (58.3%) and sedentary lifestyle (45.8%). After intervention, there was a reduction in mean values of total and LDL-cholesterol and increased HDL-cholesterol levels. The CVR and global risk score decreased significantly. The frequency of depressive symptoms decreased from 25% to 4.2%. An improvement was observed in SF-36 physical, health and vitality domains. The mixed protocol of physical exercises constituted a possible low cost and effective alternative in the improvement of the lipid profile and the quality of life related to the health of the elderly who participated in this research.

Elaboração e avaliação da aceitação de queijos processados cremosos adicionados de biomassa de banana verde / Elaboration and evaluation of the acceptance of creamous processed cheeses added from banana verde biomass

Entende-se por queijo processado o produto obtido por trituração, mistura, fusão e emulsão por meio de calor e agentes emulsionantes de uma ou mais variedades de queijo, com ou sem adição de outros produtos lácteos. A polpa de banana, quando verde, não apresenta sabor, é rica em flavonoides e amido resistente, os quais atuam na proteção da mucosa gástrica e com função de fibra alimentar no organismo humano. O presente trabalho teve por objetivo elaborar queijos processados cremosos com substituição parcial da gordura por biomassa de banana verde. Realizou-se análises físico-químicas, microbiológicas e sensoriais. Quanto ao perfil físico-quimico observou-se que as amostras estavam com valores de acidez altos e pH baixos, apresentaram alta umidade e teores de gorduras reduzidos em relação à amostra padrão (sem biomassa). Todas as amostras encontraram-se dentro do padrão microbiológico estabelecido pela Portaria 12/2011. A análise sensorial demostrou que o queijo 2 foi o que apresentou as maiores médias, para cor e consistência as médias foram 6,04 e 6,08, respectivamente, o que equivalem ao grau de aceitação “gostei muito” na escala hedônica de 7 pontos e 5,46 para o aroma, 5,88 para o sabor e 5,97 espalhabilidade, o que corresponde ao “gostei ligeiramente” na escala.

Pre-operative fasting: why abbreviate? / Jejum pré-operatório: por que abreviar?

ABSTRACT Introduction : Considering the practice of preoperative fasting based on observations on the gastric emptying delay after induction and the time of this fast is closely linked to organic response to trauma, arise the question about preoperative fasting period necessary to minimize such response and support the professional with clinical and scientific evidence. Aim : To review the aspects related to the abbreviation of preoperative fasting from the metabolic point of view, physiology of gastric emptying, its clinical benefits and the currently recommendations. Method : Literature review was based on articles and guidelines published in English and Portuguese, without restriction of time until January 2017, in PubMed, SciELO and Cochrane with the descriptors: surgery, preoperative fasting, carbohydrate. From the universe consulted, 31 articles were selected. Results : The literature suggests that the abbreviation of fasting with beverage added carbohydrates until 2 h before surgery, can bring benefits on glycemic and functional parameters, reduces hospitalization, and does not present aspiration risk of healthy patients undergoing elective surgery. Another nutrient that has been added to the carbohydrate solution and has shown promising results is glutamine. Conclusion : The abbreviation of preoperative fasting with enriched beverage with carbohydrates or carbohydrate and glutamine seems to be effective in the care of the surgical patient, optimizing the recovery from of postoperative period.

RESUMO Introdução : Considerando que a prática do jejum pré-operatório é baseada nas observações do retardo do esvaziamento gástrico após a indução anestésica e que o tempo deste jejum está intimamente ligado à resposta orgânica ao trauma, surge o questionamento acerca do período de jejum necessário para minimizar tal resposta e respaldar a atuação profissional em evidências clinicocientíficas. Objetivo : Revisar a abreviação do jejum pré-operatório, sob o ponto de vista metabólico, da fisiologia do esvaziamento gástrico, seus benefícios clínicos e recomendações atualmente vigentes. Método : A revisão foi baseada em artigos e guidelines publicados em inglês e português, sem restrição de tempo até janeiro de 2017, no PubMed, SciELO e Cochrane com os descritores: cirurgia, jejum pré-operatório, carboidrato. Do universo consultado 31 artigos foram selecionados. Resultados : A literatura aponta que a abreviação do jejum com bebida enriquecida com carboidratos até 2 h antes do procedimento cirúrgico pode trazer benefícios sobre parâmetros glicêmicos, funcionais, redução da hospitalização, além de não oferecer risco de broncoaspiração em indivíduos saudáveis submetidos à operações eletivas. Outro nutriente frequentemente adicionado a esta solução de carboidratos, com resultados promissores, é a glutamina. Conclusão : A abreviação do jejum pré-operatório com bebida enriquecida com carboidratos ou carboidratos e glutamina parece mostrar-se eficaz no cuidado ao paciente cirúrgico otimizando a recuperação do período pós-operatório.
