Relationship among Dietary Intake of Vitamin E, Lipid Peroxidation Markers, and C-Reactive Protein in Flu-Like Patients Diagnosed with COVID-19.

Objective: This research aimed to assess the intake of vitamin E and its relationship with lipid peroxidation markers and C-reactive protein levels in patients with flu symptoms and COVID-19 diagnosis. Methods: A cross-sectional study with 121 patients of both sexes assisted at two basic health units in the city of Teresina, Piauí, with COVID-19 diagnosis confirmed through real-time reverse transcription polymerase chain reaction, was performed between the 3rd and 7th days of flu symptoms. The global nutritional status and the measurement of waist circumference were assessed according to the World Health Organization recommendations. The dietary energy intake, macronutrients, and vitamin E consumption were assessed through the 24 hr food recall method. The malondialdehyde plasmatic concentration (MDA) was measured through the method of thiobarbituric acid-reactive substances. Myeloperoxidase (MPO) was assessed through the oxidation speed of the o-dianisidine substrate in the presence of hydrogen peroxide. C-reactive protein (CRP) levels were measured by a high-sensitivity immunoturbidimetry method. Results: The most common symptoms reported by the participants were sore throat, fever, and cough. Regarding the global nutritional status evaluation, the majority of the sample had overweight. The dietary intake of vitamin E was 100% inadequate and presented a mild correlation (r = 0.197) with MDA, a redox status marker. No correlation was observed among MPO, CRP, and the dietary intake of vitamin E. Conclusion: The dietary intake of vitamin E was related to MDA as the marker of redox status.

Cryolipolysis on More than One Body Area Increases Lipid Peroxidation without Changing Lipid Profile and Inflammatory Markers.

In the present study, the effects of cryolipolysis on one and multiple body areas, assessing body composition, lipid profile and peroxidation and inflammatory markers were investigated. Twenty-four women aged between 20 and 59 years were randomly assigned to three groups: (1) control, (2) cryolipolysis on the abdomen and (3) cryolipolysis on the abdomen + flanks. Anthropometric measurements, bioimpedance and ultrasound were performed, as well serum lipid profile, lipid peroxidation markers (malondialdehyde and myeloperoxidase) and inflammatory markers (C-reactive protein and Interleukin-1ß) were determined. In addition, food consumption and physical activity level were evaluated. Data were obtained at 0, 10 and 30 days (t0, t10 and t30) after cryolipolysis. Cryolipolysis did not change anthropometric measurements, body composition or lipid profile. Interestingly, the abdomen + flanks group had significantly increased plasma myeloperoxidase activity at t0, t10 and t30, and increased malondialdehyde levels at t0 and t10 when compared to the other groups. Furthermore, there were no differences between macronutrient intake and total energy value, physical activity level, malondialdehyde and interleukin-1ß at t30. Cryolipolysis did not change body composition, lipid profile or inflammatory markers investigated. On the other hand, when used on the abdomen and flanks, it produced an increase in lipid peroxidation markers, malondialdehyde and myeloperoxidase.

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.

Functional performance, nutritional status and level of physical activity of elderly

The elderly is a risk group for changes in health conditions and as well as in functional performance related to the decline in grip strength and reduced walking speed, which can compromise the performance of activities of daily living. Based on this, the objective was to analyze the factors associated with functional performance in the elderly. For that, a cross-sectional study was developed involving a group of 179 elderly people who received medical care at an outpatient clinic of the public health network. Muscle strength and gait speed were measured. Nutritional status was determined by Body Mass Index (BMI), calf circumference (CC), waist circumference (WC) and waist-to-hip ratio (WHR). Level of physical activity was measured by the adapted version of the Minnesota Leisure Activities Questionnaire. Low muscle strength was found in 20.7% of the elderly and slow gait in 20.1%. Increased risk of cardiovascular disease was found in 40.8% considering WC, and 35.2% by WHR. Most of the elderly had low weight and no loss of muscle mass. Loss of muscle strength was associated with sex and CC and gait speed were associated with sex, age, and presence of a partner (p < 0.05). The chance of loss of muscle strength and lower gait speed was higher in elderly women. Loss of muscle mass due to CC was associated with the chance of loss of strength, and the chance of reduced walking speed was greater among the elderly individuals aged 75 years and over.

Hepatic function and antioxidant activity in diabetic rats subjected to diet supplemented with multimixture.

INTRODUCTION: Food and dietetic components have received considerable attention as auxiliary feeding resources on controlling of chronic non-transmissible diseases, among them diabetes. This study evaluated the effect of supplementary diet with multimixture based on linseed, sesame, oats and sunflower seeds on the hepatic function and antioxidant activity of diabetic rats. METHODS: Male rats were distributed on groups of seven animals: diabetic control (DC), diabetics subject to multimixture diet (DM), diabetic with insulin (DI), and normal control (NC). The treatment was started on the 5th day after diabetes induction with 40 mg/kg i.v. streptozotocin on tampon citrate and kept during 50 days. RESULTS: The ethereal extract of the supplemented diet showed a higher content of phenolics (p < 0.05) compared to other extracts of the supplemented diet and the ethereal extract of the standard diet. There was no difference in antioxidant in vitro activity of the utilized diets. Concerning to transaminases, significant bigger ALT levels (p < 0.05) were present on diabetic groups compared to NC. The relative liver weight on diabetic groups was significantly higher (p < 0.001) compared to NC group. Non-proteic sulfhydryl group levels were significantly higher (p < 0.05) on DM and I groups when compared to DM and NC. Only the treatment with insulin resulted in an improvement of antioxidant activity concerning to hepatic catalase. The supplementation with multimixture did not improve the metabolic control of diabetes. CONCLUSION: The multimixture treatment showed an isolated improvement on antioxidant activity in the hepatic tissue, evidenced by the increasing on non-proteic sulfhydryl group levels.

Ângulo de fase e sua relação com albumina e risco nutricional em pacientes hospitalizados / Phase angle and its relationship with albumine and nutritional risk in hospitalized patients

Introdução: Diante da importância do diagnóstico correto e precoce do estado nutricional de pacientes hospitalizados, visto que a avaliação do estado nutricional pode ser imprescindível para manutenção da saúde e recuperação da doença e/ou trauma, o objetivo do estudo foi identificar valores de ângulo de fase em pacientes hospitalizados e sua respectiva relação com albumina e avaliação de risco nutricional. Método: Estudo transversal, descritivo e observacional, realizado com pacientes internados no Hospital Universitário da Universidade Federal do Piauí (HU-UFPI). O estado nutricional foi avaliado por meio da avaliação antropométrica (índice de massa corporal - IMC), avaliação de risco nutricional (rastreamento de risco nutricional e Mini Avaliação Nutricional), medida do ângulo de fase e albumina. Resultados: Verificou-se prevalência (52%) de adequado estado nutricional, com variação do IMC de 22,4 a 35,20 kg/m² (22,83±4,63 kg/m²), oscilação da albumina de 2,00 a 4,60 g/dL (3,68±0,73 g/dL) e o ângulo de fase padronizado variando entre -5,22 a 6,73 Xc/R (-1,23±2,83 Xc/R). Observou-se correlação positiva significativa entre o ângulo de fase padronizado (AFP) e a concentração de albumina na população investigada. Conclusão: Os resultados obtidos sugerem que o AFP pode ser um preditor do comprometimento do estado nutricional dos pacientes deste estudo. Contudo, não foi encontrada correlação desse parâmetro com os demais métodos de avaliação do estado nutricional utilizados, à exceção da albumina, com a qual o AFP apresentou correlação positiva. Assim, novos estudos são sugeridos a fim de respaldar a utilização do AFP na detecção do risco nutricional, considerando as diferentes alterações fisiológicas e celulares associadas ao mesmo, em combinação com outras ferramentas, e nas distintas populações e no ambiente hospitalar ao longo de toda a internação.

Introducción: alimentos y componentes de la dieta han recibido considerable atención como recursos auxiliares en el control de las enfermedades crónicas, como la diabetes. Este estudio evaluó el efecto de la dieta suplementada con base de linaza multimezcla, sésamo, avena y semillas de girasol en la función hepática y la actividad antioxidante de ratas diabéticas. Métodos: las ratas macho fueron divididas en grupos de siete animales: control de la diabetes (CD), diabéticos sometidos a dieta multimezcla (DM), diabéticos con insulina (DI), y control normal (CN). El tratamiento se inició en el quinto día después de la inducción de la diabetes con estreptozotocina 40 mg/kg i.v. en tampón citrato y se mantuvo durante 50 días. Resultados: la dieta extracto etéreo complementado tenía el contenido fenólico más alto (p < 0,05) que los otros extractos de la suplementación de la dieta y el extracto de éter de la comida estándar. No hubo diferencia en la actividad antioxidante in vitro de la alimentación usada. A medida que las transaminasas, los niveles de ALT significativamente mayor (p < 0,05) estuvieron presentes en el grupo de diabéticos en comparación con CN, el peso relativo del hígado en el grupo de diabéticos fue significativamente mayor (p < 0,001) en comparación con el grupo CN. Los grupos sulfhidrilo de los niveles de proteína no fueron significativamente mayores (p < 0,05) en los grupos F e I comparados con CN y CD. El tratamiento con insulina resultó en una mejora de la actividad antioxidante con respecto a la catalasa hepática. Conclusión: la suplementación con multimezcla no mejora el control metabólico de la diabetes. El tratamiento con multimezcla aislado mostró una mejora en la actividad antioxidante en el tejido hepático, como se evidencia por el aumento de los niveles de grupos sulfhidrilo no proteicos (AU)
