Background/Aims: This study aimed to evaluate the effects of the intake of a single dose of cinnamon infusion on energy metabolism, appetite responses and food intake in healthy individuals. Methods: This was an open randomized crossover clinical trial, with a minimum washout of seven days, which was conducted in which two standardized breakfasts were served randomly: one with cinnamon infusion (2g, Cinnamomum sp.) And one with water (control). The study included 21 healthy volunteers. Energy expenditure (EE), diet-induced thermogenesis (DIT), respiratory quotient (RQ), substrate oxidation and appetite responses were evaluated, as well as prospective food intake. Results: Ingestion of cinnamon infusion did not alter EE, DIT, RQ or substrate oxidation. The incremental area under the curve for hunger, satiety and desire to eat did not differ between the treatment with cinnamon infusion and water, however, there was a reduction in the feeling of satiety (p=0.021) compared to the control treatment. The energy consumption of the first meal after treatment was higher (p=0.05) in the treatment with cinnamon infusion than in the control treatment. Regarding macronutrients or food intake throughout the day, there was no difference between treatments. Conclusions: Although it did not affect energy metabolism, consuming a single dose of cinnamon infusion promoted less feeling of satiety and increased energy intake in the first meal after treatment. The study protocol was registered at the Brazilian Clinical Trials Registry Platform (RBR-5ftg3z).
The aim of this study was to investigate the effect of Hibiscus sabdariffa tea on energy expenditure, satiety response and food intake. This is an open-label, crossover, randomized clinical trial (RBR-5HZ86T), including 21 subjects (11 women, 10 men). The individuals were evaluated at acute moments (fasting and after eating standardized breakfast accompanied by water or Hibiscus sabdariffa tea). Resting energy expenditure was measured by indirect calorimetry, subjective satiety responses were evaluated with a visual analogue scale and food intake was assessed by using food records. The volunteers who drank the Hibiscus sabdariffa tea had lower perception of hunger (p=0.002) and greater feeling of satiety (p=0.010) and fullness (p=0.009) compared to control. Men who ingested the Hibiscus sabdariffa tea had an increase in nitrogen energy expenditure (water: 1501±290.7kcal, Hibiscus sabdariffa tea: 1619±288.9kcal; p=0.029). In comparison to control, men presented less perception of hunger (p=0.003) and desire to eat (p=0.016), increased satiety (p=0.021) and fullness (p=0.010), and women oxidized more fat (p=0.034) when they drank Hibiscus sabdariffa tea. There was no difference between treatments regarding the energy and macronutrient intake from the first meal and throughout the day (p>0.050) for all participants. The Hibiscus sabdariffa tea only affected energy expenditure and satiety responses in men.

Novelty bullets
• Hibiscus sabdariffa tea promoted an increase in energy expenditure and caused less perception of hunger/desire to eat in men.
• Hibiscus sabdariffa tea intake increased postprandial fat oxidation in women.
Objetivo: identificar as ações intersetoriais no contexto do atendimento e do cuidado às pessoas em situação de rua. Método: revisão integrativa da literatura, realizada nas bases de dados LILACS, MEDLINE, Cochrane, CINAHL, SCOPUS, EMBASE e Web of Science. Foram incluídos 10 estudos publicados entre os anos de 2013 e 2020. Resultados: a intersetorialidade foi apontada como necessária para o atendimento da população em situação de rua, assim, poucas experiências exitosas de articulação entre os diferentes setores foram identificadas. A falta de interação entre a assistência social e saúde foi relatada. Os serviços de assistência social são usados de forma prioritária, e os serviços de saúde são usados, em sua maioria, para o acesso aos medicamentos ou ao atendimento emergencial. Conclusão: evidenciou-se as omissões e as desarticulações entre os setores que atuam com a população de rua e que a construção de vínculo e a integração de redes formais e informais de apoio são necessárias para a garantia da intersetorialidade.
