Effects of Intuitive Eating on the Quality of Life and Wellbeing of Yoga Practitioners, Physical Activity Practitioners and Sedentary Individuals.

This study is a comparative analysis of the effects of intuitive eating and correlations with quality of life and wellbeing in Yoga practitioners, physical activity practitioners and sedentary individuals. The study involved 204 participants, comprising 66 Yoga practitioners, 74 physical activity practitioners and 64 sedentary individuals, between the ages of 20 and 59, who were resident in Brazil at the time of the study. Quantitative research was conducted through Facebook and the application questionnaires via Google Forms to measure intuitive eating, food consumption, quality of life, stress level, satisfaction with body image and level of mindfulness. The study found that while intuitive eating did not differ between Yoga practitioners and physical activity practitioners, both showed greater adoption of intuitive eating as compared to inactive individuals. Still, Yoga practitioners had better confidence in their physiological signs of hunger and satiety, as well as better eating behavior, quality of life, satisfaction with body image, healthy body weight, and stress-related emotional regulation, as compared to the other groups. In addition, there was a positive correlation between intuitive eating and quality of life, body esteem, mindfulness and eating behaviors that discouraged eating in response to external or psychological influences, and a negative correlation to stress and weight gain. This study finds that physical exercise, in particular the practice of Yoga, is linked to the promotion of better intuitive eating behavior as well as better quality of life and wellbeing.

Relationship between GSTM1 and GSTT1 polymorphisms and HPV infection: a systematic review.

Human Papillomavirus (HPV) is the most important risk factor for cervical cancer, although not the only one. The allelic polymorphism of enzymes acting on carcinogen metabolism has shown to influence the risk of both intraepithelial lesions and cervical carcinogenesis. Several studies found an association between GSTM1/GSTT1 null genotypes and risk of cancer. This research aimed to review studies addressing the relationship between GSTT1 and GSTM1 and HPV infection in women, with or without cervical pathologies. A database search was conducted in four databases - PubMed, LILACS, SciELO, and Virtual Health Library - using the following descriptors: Glutathione transferase, HPV, and Genetic polymorphism. In total, we found 319 studies. After screening titles and abstracts, 27 articles were selected for full-text read, among which 20 were excluded and 7 were included in the review. No study has exclusively approached the relationship between the virus and GSTM1/GSTT1 variants. However, studies investigating the association between single nucleotide polymorphisms (SNPs) and cervical lesions or cancer found a probable relationship between them and infections with high-risk oncogenic subtypes. Although inconclusive, GSTT1 null alleles were more common in women with more aggressive HPV than GSTM1.

Avaliação do status oxidativo, consumo alimentar de zinco e zinco plasmático em indivíduos infectados pelo HIV / Evaluation of oxidative status, food consumption of zinc and plasma zinc in HIV-infected individuals

Objetivo: Objetivou-se analisar o consumo alimentar e os níveis plasmáticos de zinco além de biomarcadores do status oxidativo de pacientes com infecção pelo HIV. Métodos: Foram selecionados indivíduos adultos com HIV e contagem de linfócitos T CD4<500 células/mm3, assistidos por um centro especializado, localizado na região oeste do Paraná. Realizou-se a aplicação de questionários, avaliação antropométrica e coleta sanguínea para análise de zinco e biomarcadores do status oxidativo. Resultados: Avaliou-se um total de quarenta indivíduos adultos, nos quais se observaram consumo adequado de zinco e grande frequência de eutrofia e sobrepeso. Obteve-se correlação positiva entre tióis proteicos (SH-P) e os níveis plasmáticos de zinco e correlação negativa entre SH-P e a peroxidação lipídica (PL) no plasma e nos eritrócitos. Além disso, verificou-se um aumento nos níveis de SH-P em pacientes com presença de doença oportunista em alguma fase da infecção viral. Conclusão: Apesar de não ter sido observada relação entre níveis de zinco sanguíneo e a contagem de linfócitos T CD4 e carga viral, as propriedades do mineral ainda são defendidas como essenciais.
