Association of Val16Ala Polymorphism of Manganese Superoxide Dismutase (MnSOD) with Food Intake and Cardiometabolic Risk Factors in the Elderly in Primary Care in Porto Alegre.

BACKGROUND: The aging process causes physiological changes on its own. The combination of an unhealthy lifestyle with the presence of genetic polymorphisms, such as the Val16Ala of the antioxidant enzyme manganese-dependent superoxide dismutase (MnSOD) may contribute to a greater occurrence of cardiometabolic risk factors. OBJECTIVE: This study aimed to verify the association of Val16Ala-MnSOD polymorphism with food intake, caloric expenditure, and cardiometabolic risk factors in the elderly. METHODS: A cross-sectional study with a sample size of 270 elderly individuals assisted in primary health care in the city of Porto Alegre, RS, Brazil. Val16Ala polymorphism, glucose, lipid profile, insulin, HOMA-IR, blood pressure, waist circumference, PCR-us, IL-6, food consumption, and caloric expenditure were evaluated. RESULTS: The average age of the elderly was 68.6 ± 7.6 years. There were statistically significant differences regarding the consumption of two or more servings of fruits and vegetables daily between the elderly VV versus AV (P=0.017). There were also statistically significant differences regarding the consumption of two or more daily servings of legumes and eggs between the elderly AA versus VV (P=0.002). The median of insulin was higher in the elderly AA versus AV (P=0.025) and the median of HOMA-IR was higher in the elderly VV versus AV (P=0.029). AA elderly individuals had higher means of high-density lipoprotein (HDL-c), compared to AV (P=0.029). CONCLUSION: The results suggest that Val16Ala -MnSOD polymorphism is associated with the consumption of fruits, vegetables, legumes, and eggs, as well as with cardiometabolic risk factors in the elderly.

Effects of Spices (Saffron, Rosemary, Cinnamon, Turmeric and Ginger) in Alzheimer's Disease.

Alzheimer's disease (AD) is the most prevalent dementia in the elderly, causing disability, physical, psychological, social, and economic damage to the individual, their families, and caregivers. Studies have shown some spices, such as saffron, rosemary, cinnamon, turmeric, and ginger, have antioxidant and anti-inflammatory properties that act in inhibiting the aggregation of acetylcholinesterase and amyloid in AD. For this reason, spices have been studied as beneficial sources against neurodegenerative diseases, including AD. In this sense, this study aims to present a review of some spices (Saffron, Rosemary, Cinnamon, Turmeric and Ginger) and their bioactive compounds, most consumed and investigated in the world regarding AD. In this article, scientific evidence is compiled in clinical trials in adults, the elderly, animals, and in vitro, on properties considered neuroprotective, having no or negative effects on neuroprotection of these spices and their bioactive compounds. The importance of this issue is based on the pharmacological treatment for AD that is still not very effective. In addition, the recommendations and prescriptions of these spices are still permeated by questioning and lack of robust evidence of their effects on neurodegeneration. The literature search suggests all spices included in this article have bioactive compounds with anti-inflammatory and antioxidant actions associated with neuroprotection. To date, the amounts of spice ingestion in humans are not uniform, and there is no consensus on its indication and chronic consumption guarantees safety and efficacy in neuroprotection. Therefore, clinical evidence on this topic is necessary to become a formal adjuvant treatment for AD.

Efeitos dos medicamentos hipolipêmicos no perfil lipídico de população idosa de Porto Alegre, RS, Brasil / Effects of hypolipemic drugs on the lipidic profile of Porto Alegre, RS, Brasil in older population

O perfil lipídico pode estar relacionado com doenças crônico-degenerativas e suas complicações. Alguns dos medicamentos usados para controlar os níveis lipêmicos são estatinas e fibratos. O objetivo deste trabalho foi verificar o perfil lipídico da população idosa de Porto Alegre, RS, Brasil, que faz uso desses medicamentos. Foram coletadas amostras de sangue de 456 idosos e as dosagens foram realizadas através da metodologia química seca. Para análise estatística foram utilizados os testes Student e Qui-quadrado. Analisou-se o perfil lipídico de 22 homens e 51 mulheres que faziam uso de medicamentos hipolipêmicos e comparou-se esse perfil com o de 85 homens e 161 mulheres que não faziam uso destes. Os resultados demonstraram diferença significativa na classificação dos riscos e nos valores médios de colesterol total, LDL e triglicerídeos, nas idosas que usavam hipolipêmicos em relação às quenão os utilizavam. No entanto, para os homens, ocorreu uma diminuição significativa nos resultados de LDL, nos que faziam uso dos hipolipêmicos, apresentando valores controlados para todos os índices. É necessário um maior acompanhamento para a utilização correta dos medicamentos citados pelas pacientes idosas, a fim de se obter um melhor controle da lipemia e uma melhoria nas condições de saúde dessas pacientes.

The lipidic profile can be related to chronic degenerative diseases and their complications. Some of the drugs used to control the lipidic levels are statins and fibrates. The aim of the study was to verify the lipidic profile of the elderly population of Porto Alegre, RS, Brazil that makes use of these medicines. Blood samples were collected from 465 elderly and the dosages were determined by drought chemical methodology. For statistical analysis were used the Student t test and Chi-square test. There were examined the lipidic profile of 22 men and 51 women that made use of hypolipemic drugs and compared with 85 men and 161 women that did not use these. The results showed significant differences in the classification of risk and the average values of total cholesterol, LDL and triglycerides in the elderly that used hypolipemic in relation to those that did not use. However, for men there was a significant decrease in LDL results of those that made use of hypolipemic drugs, presenting controlled values for all indexes. It’s necessary a better monitoring for the correct use of the drugs mentioned by elderly women patients in order to get a better control of lipidic profile and an improvement in the health conditions of these patients.
