Validity and reliability of the Brazilian version of the Cognitive Reserve Assessment Scale in Health

Objective: As the older population increases, it is important to identify factors that may reduce the risks of dementia in the general population. One such factor is the concept of cognitive reserve (CR). The present study analyzed the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH) in the Brazilian population. This scale was originally developed to measure CR in individuals with severe mental illness. We also investigated the relationship between the CRASH and clinical or sociodemographic variables. Methods: This study was conducted with 398 individuals. We assessed sociodemographic variables and depression, anxiety, and stress symptoms (Depression, Anxiety and Stress Scale [DASS-21]) using a web-based survey. We constructed a confirmatory factor analysis (CFA) model in order to test the goodness of fit of the factor structure proposed in the original CRASH study. Results: The McDonald's hierarchical ω for CRASH using CFA parameters was 0.61, and the Cronbach's alpha coefficient indicated good internal consistency when considering all items (alpha = 0.7). Conclusions: Our results suggest that CRASH can be used to assess CR in the general population in Brazil.

O impacto da primeira onda da pandemia de Covid-19 na saúde mental de estudantes brasileiros / The impact of the first wave of the Covid-19 pandemic on the mental health of Brazilian students

Com a alta disseminação do novo coronavírus, foi necessário adotar intervenções de saúde pública com foco no distanciamento social para diminuir a transmissão do patógeno causador, o SARS-Cov-2. Contudo, essas medidas podem contribuir para o aumento do sofrimento emocional, gerando níveis mais elevados de ansiedade, depressão e estresse. Desse modo, o objetivo deste estudo foi investigar os efeitos da pandemia de Covid-19 na saúde mental de estudantes brasileiros através de uma pesquisa levantamento de dados on-line. A pesquisa foi realizada durante o período da primeira onda da pandemia no Brasil. Foram avaliadas variáveis sociodemográficas, de saúde mental, incluindo sintomas de depressão e ansiedade, e qualidade de vida em uma amostra final de 810 estudantes. Os sintomas psiquiátricos mais prevalentes foram ansiedade (89,5%), depressão (77,9%) e raiva (72,3%). Tempo de distanciamento social, idade e diagnóstico prévio de doenças psiquiátricas foram significativamente associados à maior gravidade dos sintomas de ansiedade e depressão. O alto grau de sofrimento emocional apresentado por essa amostra indica a necessidade de adotar estratégias que visem promover a saúde mental de estudantes, e proporcionar acompanhamento psicológico de alunos durante e após esse período crítico de isolamento social.(AU)

With the high spread of the new coronavirus, it was necessary to adopt public health interventions focused on social distancing to reduce the transmission of the causative pathogen, SARS-Cov-2. However, these measures can contribute to increased emotional distress, generating higher levels of anxiety, depression and stress. Thus, the aim of this study was to investigate the effects of the Covid-19 pandemic on the mental health of Brazilian students through an online data collection survey. The survey was carried out during the period of the first wave of the pandemic in Brazil. Sociodemographic, mental health (e.g., symptoms of depression and anxiety), and quality of life variables were evaluated in a final sample of 810 students. The most prevalent psychiatric symptoms were anxiety (89.5%), depression (77.9%) and anger (72.3%). Time of social distancing, age and previous diagnosis of psychiatric illness were significantly associated with greater severity of anxiety and depression symptoms. The high degree of emotional distress presented by this sample indicates the need to adopt strategies aimed at promoting the mental health of students and providing psychological support for students during and after this critical period of social isolation.(AU)

Con la alta propagación del nuevo coronavirus, fue necesario adoptar intervenciones de salud pública enfocadas en el distanciamiento social para reducir la transmisión del patógeno causante, SARS-Cov-2. Sin embargo, estas medidas pueden contribuir a aumentar la angustia emocional, generando mayores niveles de ansiedad, depresión y estrés. Por lo tanto, el objetivo de este estudio fue investigar los efectos de la pandemia Covid-19 en la salud mental de los estudiantes brasileños a través de una encuesta de recolección de datos en línea. La encuesta se llevó a cabo durante el período de la primera ola de la pandemia en Brasil. Se evaluaron variables sociodemográficas, de salud mental, incluyendo síntomas de depresión y ansiedad, y calidad de vida en una muestra final de 810 estudiantes. Los síntomas psiquiátricos más prevalentes fueron ansiedad (89,5%), depresión (77,9%) e ira (72,3%). El tiempo de distanciamiento social, la edad y el diagnóstico previo de enfermedad psiquiátrica se asociaron significativamente con una mayor gravedad de los síntomas de ansiedad y depresión. El alto grado de angustia emocional que presenta esta muestra indica la necesidad de adoptar estrategias dirigidas a promover la salud mental de los estudiantes y brindar apoyo psicológico a los estudiantes durante y después de este período crítico de aislamiento social.(AU)

Aceitabilidade e fatores associados ao consumo dietético em pacientes diabéticos de um hospital público universitário / Acceptability and factors associated with dietary consumption in diabetic patients of a public university

A dietoterapia é essencial para pacientes hospitalizados. O objetivo deste estudo foi avaliar a aceitabilidade das refeições do almoço de pacientes que receberam a dietética para Diabetes Mellitus (DM) e verificar aspectos que podem interferir nesse consumo, como as estações do ano. Estudo quantitativo descritivo que avaliou o consumo da refeição almoço dos pacientes que receberam dietética DM em um período de verão e outro de inverno no ano de 2019. Os dados foram verificados em frequências absolutas, porcentagens, médias, e o teste estatístico foi o de regressão logística com a correlação de dados a um nível de significância de 95% (p <0,05) usando o software SPSS® 18.0. Foram selecionadas duas unidades de internação, com amostra de 49 indivíduos (63,3% do sexo masculino). Das 115 refeições servidas, 55,7% foram parcialmente consumidas ou não consumidas. O desperdício de pratos nas refeições do almoço apresentou média per capita de 64,15 g (consumo de 310,89g) no verão e de 135,99g (consumo de 248,12g) no inverno. O padrão do cardápio foi semelhante nas duas estações. Encontrou-se p <0,05 em relação à temporada na associação do odds ratio univariável. Pesquisas dessa natureza são importantes para auxiliar no prognóstico do paciente. (AU)

Diet therapy is essential for hospitalized patients. This study aimed to evaluate the acceptability of lunch meals in patients who received diet for diabetes mellitus (DM) and to verify aspects that may interfere with this consumption, such as seasons. This is a quantitative, descriptive study. The consumption of lunch meal in patients who received dietary DM in summer and a winter period in 2019 was evaluated. The data were verified in absolute frequencies, percentages, means, and the statistical test was the logistic regression with the association data at a 95% significance level (p <0.05) using the SPSS® 18.0 software. Two inpatient units were selected, with a sample of 49 individuals (63.3% males). Out of the 115 lunch meals served, 55.7% were partially consumed or not consumed. The plate waste for the lunch meals showed a mean per capita of 64.15 g (intake of 310.89g) in the summer and of 135.99g (intake of 248.12g) in winter. The menu pattern was similar for both seasons. It was found p <0.05 in relation to the season in the association of univariable odds ratio. This typo of research is important to assist in the patient's prognosis. (AU)

Cafeteria diet increases liquid intake and serum creatinine levels in rats

Introduction: Important changes in human dietary pattern occurred in recent decades. Increased intake of processed foods leads to obesity, which is related with the development of chronic diseases such as type 2 diabetes mellitus, hypertension, as well as cardiovascular and chronic kidney diseases. The prevalence of hypertension has also dramatically increased in recent years, and high sodium intake contributes to this scenario. In healthy individuals, kidneys are the primary end-organs that regulate sodium homeostasis. This study aims to evaluate renal function parameters and systolic blood pressure measurements in an animal model of obesity. Methods: Sixty-day-old male Wistar rats (n=30) were divided into two groups: standard (SD) and cafeteria diet (CD). Cafeteria diet was altered daily and was composed by crackers, wafers, sausages, chips, condensed milk, and soda. All animals had free access to water and chow and the experiment was carried out for 6 weeks. Weight gain, sodium and liquid intake control, systolic blood pressure measurements, and renal function parameters were evaluated. Results: Animals exposed to cafeteria diet had an increase of 18% in weight compared to the control group. Sodium intake was increased by cafeteria diet and time (F(1,28)=773.666, P=0.001 and F(5,28)=2.859, P=0.02, respectively) and by the interaction of both factors (F(6,28)=2.859, P=0.02). On liquid intake occurred only effect of cafeteria diet and time (F(1,28)=147.04, P=0.001 and F(5,28)=3.996, P=0.003, respectively). Cafeteria diet exposure also induced an increase on creatinine serum levels (P=0.002), however this effect was not observed on creatinine urine levels (P>0.05) nor on systolic pressure measurements (Students' t test, P>0.05). Conclusions: Obesity induced by cafeteria diet exposure increases liquid intake and alters creatinine serum levels, an important renal function marker. Considering the high consumption of hypercaloric food currently in the world, further studies are required to elucidate the modifications on renal function triggered by this diet over time (AU)

Soft drink consumption reduces food intake in Wistar rats / Consumo de refrigerante reduz a ingestão de alimentos em ratos Wistar

AIMS: To evaluate the effect of caloric and non-caloric soft drink intake on food consumption, body weight and composition, and metabolic parameters in rats. METHODS: Controlled experimental study in which 30 male Wistar rats were divided into three groups and given food and beverage ad libitum during 17 weeks. The groups were as follows, according to the offered food: Control group ­ standard chow and water; Caloric soft drink group ­ standard chow, caloric soft drink, and water; and Non-caloric soft drink group ­ standard chow, non-caloric soft drink, and water. RESULTS: There was no statistical difference in total energy intake, body weight, and fat deposition between groups. However, the chow energy intake was 45% lower in the caloric soft drink group compared to the control and non-caloric soft drink groups (198.7±0.7 kJ vs. 349.4±2.0 and 373.0±1.3 kJ, respectively), with 46% of the energy provided by the soft drink. The caloric soft drink group consumed 22% more carbohydrate, especially sucrose, compared to the control group (p<0.05). Macronutrient intake was not different between the control and non-caloric soft drink groups, but the caloric soft drink group consumed less protein and lipids when compared to the other groups (3.5±1.0 g of protein vs. 6.2±0.1 and 6.7±0.1 g, respectively; 0.7±0.01 g of lipids vs. 1.3±0.02 g and 1.4±0.02 g, respectively). Consumption of non-caloric soft drinks increased total sodium intake and consumption of both soft drinks decreased water intake. Although body weight varied during the experiment, there was no significant difference between groups at the end of the experiment, and no difference in fat deposition, fasting glucose, insulin and leptin, insulin resistance index, and lipid profile. CONCLUSIONS: The consumption of both types of soft drinks did not affect energy intake, body weight and composition, or metabolic parameters; however, it increased fluid intake and decreased water ingestion. Caloric soft drink intake influenced the amount and the quality of solid food consumed, compromising diet quality.

OBJETIVOS: Avaliar o efeito do consumo de refrigerante calórico e não calórico sobre a ingestão alimentar, composição corporal, massa corporal e parâmetros metabólicos em ratos. MÉTODOS: Estudo experimental com grupo controle. Trinta ratos Wistar machos foram divididos em três grupos e receberam alimentos e bebidas ad libitum. Os grupos foram os seguintes, conforme o alimento oferecido: Grupo controle ­ ração padrão e água; Grupo refrigerante calórico ­ ração padrão, refrigerante calórico e água; e Grupo refrigerante não calórico ­ ração padrão, refrigerante não calórico e água. RESULTADOS: Não houve diferença estatística na ingestão total de energia, peso corporal e depósito adiposo entre os grupos. Entretanto, a ingestão de energia da ração foi 45% menor no Grupo refrigerante calórico comparado ao Grupo controle e ao Grupo refrigerante não calórico (198,7±0,7 kJ vs. 349,4±2,0 kJ e 373,0±1,3 kJ, respectivamente), sendo 46% da energia proveniente do refrigerante. O grupo refrigerante calórico consumiu 22% mais carboidrato, especialmente sacarose, comparado ao Grupo controle (p<0,05). A ingestão de macronutrientes não foi diferente entre o Grupo controle e o Grupo refrigerante não calórico, mas o Grupo refrigerante calórico consumiu menos proteína e lipídios que os outros dois (3,5±1,0 g de proteína vs. 6,2±0,1 e 6,7±0,1 g, respectivamente; 0,7±0,01 g de lipídios vs. 1,3±0,02 g e 1,4±0,02 g, respectivamente). O consumo de refrigerante não calórico aumentou a ingestão total de sódio e o consumo de ambos os refrigerantes diminuiu a ingestão de água. Embora a massa corporal tenha variado durante o experimento, não houve diferença significativa entre os grupos ao final do mesmo e, igualmente, não houve diferença no depósito adiposo, glicose, insulina e leptina em jejum, índice de resistência à insulina e perfil lipídico. CONCLUSÕES: A ingestão de ambos os refrigerantes (calórico e não calórico) não afetou a ingestão de energia, composição e massa corporal e parâmetros metabólicos, entretanto aumentou a ingestão de fluidos e diminuiu a de água. A ingestão de refrigerante calórico influenciou a quantidade e qualidade de comida sólida consumida, comprometendo a qualidade da dieta.
