Vegetarian and plant-based diets associated with lower incidence of COVID-19.

Objective: To evaluate the influence of dietary patterns on the incidence and evolution of COVID-19. We hypothesised that a plant-based diet or a vegetarian diet compared with an omnivorous diet might be associated with a lower incidence of COVID-19 infection and severity in those infected. Design: In this observational study, 702 participants provided information on sociodemographic characteristics, dietary information and COVID-19 outcomes between March and July of 2022. Individuals were divided into two groups based on their dietary habits, omnivorous (n=424) and plant-based (n=278). The plant-based group was further divided into vegetarian and flexitarian subgroups. The groups were compared with respect to the incidence of COVID-19 infection, severity and duration. We used multivariable logistic regression models to evaluate the influence of dietary patterns. Results: Plant-based and vegetarian groups had a higher intake of vegetables, legumes and nuts, and lower intake of dairy and meat. After adjusting for important confounders, such as body mass index, physical activity and pre-existing medical conditions, the plant-based diet and vegetarian group had 39% (OR=0.61, 95% CI 0.44 to 0.85; p=0.003) and 39% (OR 0.61, 95% CI 0.42 to 0.88; p=0.009) lower odds of the incidence of COVID-19 infection, respectively, compared with the omnivorous group. No association was observed between self-reported diets and COVID-19 severity or duration. Conclusion: Plant-based and mainly vegetarian diets were associated with a lower incidence of COVID-19 infection. These dietary patterns may be considered protective against COVID-19 infection.

Could there be a slower physiological healing process in vegan individuals?

The article "Comparing Tattoo Removal Responses in Vegan and Omnivore Patients" by Fusano et al. investigates the clinical outcomes of Q-switched laser tattoo removal in vegans and omnivores. The study reveals that vegans required more laser sessions, exhibited poorer clinical responses, and experienced extended healing periods compared to omnivores. When well-planned vegetarian diets offer numerous health benefits. Unfortunately, the study does not assess the diets of the groups, nor does it address factors like hydration levels and prior skincare regimens, limiting the interpretation of results.

Consumption of animal-based and processed food associated with cardiovascular risk factors and subclinical atherosclerosis biomarkers in men.

OBJECTIVE: To evaluate the frequency of food consumption in apparently healthy men and their association with cardiovascular risk factors and biomarkers of subclinical atherosclerosis. METHODS: In this observational study, 88 men had their food standard obtained through the food frequency questionnaire (FFQ). Associations of dietary patterns with cardiovascular risk factors, such as anthropometric data, laboratory and clinical evaluations, carotid-femoral arterial stiffness (IMT) and pulse wave velocity were evaluated. RESULTS: The highest values were observed, for most of the risk factors evaluated, with the highest frequency of weekly consumption of dairy products, meats, sweets, fats, cold meats, sodas, milk and white chocolate; and lower frequency of weekly consumption of fruits, cereals, vegetables, legumes, oilseeds, and soy. There was no significant difference for coffee and dark chocolate. CONCLUSIONS: A diet with high consumption of animal products has a higher correlation with cardiovascular risk factors; the opposite is true for the consumption of plant-based food, associated with the profile of more favorable biomarkers for cardiovascular health and better biochemical and structural parameters.

RESUMO OBJETIVO Avaliar a frequência do consumo alimentar de indivíduos homens aparentemente saudáveis e a associação desta com fatores de risco cardiovascular e biomarcadores de aterosclerose subclínica. MÉTODOS Neste estudo observacional, 88 homens tiveram o padrão alimentar obtido por meio do questionário de frequência alimentar (QFA). Foram avaliadas as associações dos padrões alimentares com os fatores de risco cardiovascular, como dados antropométricos, avaliações laboratoriais e clínica, rigidez arterial determinada pela carótida-femoral (IMT) e velocidade da onda de pulso (VOP). RESULTADOS O padrão observado para a maioria dos fatores de risco avaliados foi de valores mais altos, segundo maior frequência de consumo semanal de lácteos, carnes, doces, gorduras/frituras, embutidos, refrigerantes, chocolates ao leite e branco; e de menor frequência de consumo semanal de frutas, cereais, legumes, verduras, leguminosas, oleaginosas e soja. Não houve diferença significativa para café e chocolate amargo. CONCLUSÕES Uma dieta com alto consumo de produtos animais apresenta maior correlação com fatores de risco cardiovascular, sendo o oposto para o consumo de alimentos de origem vegetal, associado ao perfil de biomarcadores de saúde cardiovascular mais favorável e melhores parâmetros bioquímicos e estruturais.

Legislação de propriedade industrial do Brasil e México no contexto do Acordo Trips e da epidemia da AIDS: um estudo comparativo / Industrial property law of Brazil and Mexico in the context of Trips Agreement and Aids epidemy: a comparative study

Este trabalho teve o objetivo de analisar retrospectivamente o significado de intersecção de dois fenômenos sociomodernos. Em primeiro lugar, a epidemia de HIV/AIDS (vírus da Imunodeficiência Humana/ Síndrome de Imunodeficiência Adquirida), com suas características históricas pouco usuais e alta letalidade; e, por sua vez, a intrusão de leis de propriedade intelectual na sociedade, como o Acordo Trips (Trade Related Intellectual Property Subjects), com amplas repercurssões sobre a saúde pública, sendo aqui tratados especificamente os casos de Brasil e México. Ambos os países modificaram suas leis de propriedade intelectual (LPI), para implementar o Acordo Trips (e, no caso do México, tambémo Nafta)nas últimas duas décadas, levando a patamares mais elevados de proteção de propriedade intelectual no México, quando comparado ao Brasil. Essas mudanças, porém, podem ter contribuído, no caso do México, para um menor rendimento e eficácia de seu programa de combate à epidemia de AIDS/HIV já que, para dar uma cobertura mais adequada de tratamento com medicamentos antirretrovirais (ARVs) a sua população, teve que enfrentar maiores dificuldades para sua aquisição. No substrato dos fatores de natureza econômica e política, dentre eles a maior ou menor magnitude da influência política dos Estados Unidos e interesses econômicos de suas empresas transnacionais sobre ambos os países.
