Title: Relação entre horário da alimentação e consumo de ultraprocessados em mulheres sobreviventes ao câncer de mama em tratamento com inibidores de aromatase e tamoxifeno Abstract: Breast cancer is the most prevalent malignant neoplasm among women in Brazil, and advances in diagnosis and treatment have resulted in a growing number of survivors on continuous adjuvant endocrine therapy, such as tamoxifen (TMX) and aromatase inhibitors (AI). This study aimed to evaluate the association between meal timing and ultra-processed food (UPF) consumption in 173 breast cancer survivors using TMX (n=84) or AI (n=89). Dietary intake was assessed by 24-hour dietary recall, with foods classified according to the NOVA system. Multiple linear regression models were fitted for each treatment group. Although chrononutrition patterns were similar between groups, the associations differed according to treatment. In the TMX group, later timing of the first food intake was associated with lower consumption of unprocessed or minimally processed foods and higher participation of UPF in the diet, while later timing of the last food intake and dietary midpoint were associated with higher energy intake. In the AI group, associations were concentrated on energy intake and macronutrient distribution, with no significant associations with UPF consumption. The findings reinforce the importance of incorporating chrononutrition principles into the nutritional care of breast cancer survivors.

Title: Análise demográfica das percepções sobre cigarros eletrônicos: um estudo sobre a influência da raça e escolaridade Abstract: This article aimed to analyze perceptions, practices, and social positions related to the use of electronic nicotine delivery systems (ENDS), considering race/skin color and educational level as central variables among participants in the municipality of Uberlândia, Minas Gerais, Brazil. This is an opinion survey with a quantitative approach, using a cross-sectional, observational, and descriptive design, conducted between August and December 2024. The sample consisted of 202 adult individuals, selected by convenience in public spaces with high pedestrian flow. Data were collected through a structured questionnaire and analyzed using SPSS software, applying descriptive statistics and association tests, with a significance level of p < 0.05. The results indicated a high level of self-reported knowledge about ENDS across all racial groups and educational levels, although relevant variations were observed regarding use patterns, trust in received information, and regulatory positioning. Greater supportfor a complete ban was identified among Indigenous and mixed-race participants, as well as among individuals with lower educational attainment, while the media predominated as the main source of information. It is concluded that race/skin color and educational level significantly influence perceptions and attitudes toward electronic cigarettes, highlighting the need for public policies and educational strategies sensitive to social inequalities and social determinants of health

Title: Impactos da pobreza menstrual em adolescentes de países classificados como de baixa e média renda: revisão de literatura Abstract: Adolescence is a period marked by important biological, psychological, and social transformations, in which menstruation represents a significant physiological event. However, the lack of access to resources, adequate infrastructure, health services, and information for proper menstrual hygiene management characterizes menstrual poverty, a condition that particularly affects adolescents in low- and middle-income countries and has repercussions on different aspects of health and quality of life. This study aimed to analyze the scientific evidence published in the last five years regarding the impacts of menstrual poverty on the lives of adolescents aged 10 to 19 years living in low- and middle-income countries. This is an integrative literature review structured through the PICO strategy and conducted in the PubMed, Scopus, Web of Science, and SciELO databases. The selection of the ten included studies followed previously established criteria, and a standardized instrument was used for data extraction and analysis. The results demonstrated that menstrual poverty is associated with physical health impairments resulting from inadequate menstrual hygiene conditions and mental health consequences related to feelings of shame, fear, anxiety, and low self-esteem. Furthermore, educational repercussions were identified, including school absenteeism and learning difficulties, as well as social impacts related to restrictions on participation in daily activities and the perpetuation of gender inequalities. Cultural aspects, including menstrual taboos, beliefs, and stigmas, were identified as factors that intensify the impacts observed across the analyzed dimensions. It is concluded that menstrual poverty constitutes a complex and multifaceted phenomenon with significant repercussions on adolescents’ health, education, and social inclusion, highlighting the need for intersectoral actions aimed at promoting menstrual dignity and reducing health inequalities.
