Objetivo: Discutir sobre as influências das questões de gênero na construção da sexualidade na adolescência. Método: foi realizada uma pesquisa com levantamento dos artigos na base de dados na Biblioteca Virtual de Saúde utilizando os descritores sexualidade, adolescente e identidade de gênero. Foram selecionados cinco artigos que atenderam os critérios de inclusão e tinham relevância com o tema proposto. Resultado: A construção da sexualidade é processual, sendo influenciada desde o nascimento. Na adolescência essa construção tende a ser influenciada pela escola, família, ambientes coletivos e sociais e seus vínculos. As percepções dos adolescentes refletem os padrões e normas estabelecidos na construção histórica da sociedade. Conclusão: Portanto, é importante que nesta fase de vulnerabilidades, descobertas e transformações biológicas e psicológicas, que as questões de gênero sejam discutidas, visto que, esta é parte constituinte da sexualidade e é necessário que esta seja construída sem preconceitos.

Throughout history, Sexuality Education (SE) has undergone many changes in formal education curricula. The education systems should incorporate SE and promote an understanding of sexuality from the critical perspective of gender. Objectives: To examine the approach to SE in young people in Spain and Portugal, considering the incorporation of the gender perspective, and analyze the legislation in both countries. A scoping review was conducted considering studies with SE programs, gender perspective, and legislation in Spanish, Portuguese, and English, without any time limits. The population consisted of young people aged 10 to 18 years who did not attend higher education. Databases used: CINAHL Complete, ERIC, LILACS, SciELO, MEDLINE, Psychology and Behavioral Sciences Collection, Scopus, Open Access Scientific Repository of Portugal, Base de Datos de Tesis Doctorales, Theses and Dissertations Online, and governmental websites. Thirty-two studies were found, including intervention, diagnosis, and documental programs. Eight of the studies adopted the gender perspective. Legislation in both countries is vast, with 23 main references. Although SE is legislated in both countries, the social-health and educational programs are insufficient. The relevance of the gender perspective is not incorporated into SE.

Introduction: Thoracic perivascular adipose tissue (tPVAT) has a phenotype resembling brown AT. Dysfunctional tPVAT appears to be linked to vascular dysfunction. Methods: We evaluated uncoupling protein (UCP)-1 expression by western blot, oxidative stress by measuring lipid peroxidation and the antioxidant capacity by high-performance liquid chromatography and spectrophotometry, and mitochondrial respiration by high-resolution respirometry (HRR) in tPVAT, compared to inguinal white AT (iWAT), obtained from non-diabetic (NDM) and streptozocin-induced diabetic (STZ-DM) mice. Mitochondrial respiration was assessed by HRR using protocol 1: Complex I and II oxidative phosphorylation (OXPHOS) and protocol 2: Fatty acid oxidation (FAO) OXPHOS. OXPHOS capacity in tPVAT was also evaluated after UCP-1 inhibition by guanosine 5'-diphosphate (GDP). Results: UCP-1 expression was higher in tPVAT when compared with iWAT in both NDM and STZ-DM mice. The malondialdehyde concentration was elevated in tPVAT from STZ-DM compared to NDM mice. Glutathione peroxidase and reductase activities, as well as reduced glutathione levels, were not different between tPVAT from NDM and STZ-DM mice but were lower compared to iWAT of STZ-DM mice. OXPHOS capacity of tPVAT was significantly decreased under UCP-1 inhibition by GDP in protocol 1. While there were no differences in the OXPHOS capacity between NDM and STZ-DM mice in protocol 1, it was increased in STZ-DM compared to NDM mice in protocol 2. Moreover, complex II- and FAO- linked respiration were elevated in STZ-DM mice under UCP-1 inhibition. Conclusions: Pharmacological therapies could be targeted to modulate UCP-1 activity with a significant impact in the uncoupling of mitochondrial bioenergetics in tPVAT.

Resumo Objetivos mapear programas de intervenção para crianças, adolescentes e pais, ou díade (doentes oncológicos e filhos) a vivenciar o cancro parental. Método scoping review segundo a metodologia recomendada pelo Joanna Briggs Institute (JBI) e o Preferred Reporting Items for Systematic Reviews - Scoping Reviews (PRISMA-ScR). Resultados foram identificados 29 programas de intervenção: 13 dirigidos à díade, 11 a crianças e adolescentes e 5 dirigidos aos pais. Dos programas identificados, 10 não especificam a tipologia das intervenções propostas, 9 referenciam intervenções psicoeducacionais, 7 referenciam intervenções educacionais e 3 referenciam intervenções do tipo psicossocial. Conclusão e Implicações para a prática verificou-se que a maioria dos programas identificados se dirige à díade crianças/adolescentes e pais. As caraterísticas dos programas e das intervenções diferem entre estudos, no entanto as intervenções psicoeducacionais são as mais prevalentes. O mapeamento de programas de intervenção e promoção da adaptação ao cancro parental contribui para a síntese da evidência existente sobre esta temática, conhecimento sobre as intervenções desenvolvidas e resultados obtidos, consciencializando os profissionais de saúde, nomeadamente enfermeiros, e decisores da área da saúde para a relevância da sua implementação na prática clínica, tendo em vista a qualidade dos cuidados de enfermagem prestados a essas famílias.

Dysfunction in key cellular organelles has been linked to diabetic complications. This study intended to investigate the alterations in the unfolded protein response (UPR), autophagy, and mitochondrial function, which are part of the endoplasmic reticulum (ER) stress response, in wound healing under diabetes conditions. Wound healing mouse models were used to evaluate the UPR, autophagy, mitochondrial fusion, fission, and biogenesis as well as mitophagy in the skin of control and diabetic mice at baseline and 10 days after wounding. The autophagic flux in response to high glucose conditions was also evaluated in keratinocyte and fibroblast cell cultures. Wound healing was impaired in the diabetic mouse model, and we found that the UPR and autophagy pathways were activated in skin wounds of control mice and in non-wounded skin of diabetic mice. Moreover, high glucose conditions induced autophagy in the keratinocyte and fibroblast cell cultures. However, mitophagy did not change in the skin of diabetic mice or wounded skin. In addition, mitochondrial fusion was activated in control but not in the skin diabetic wounds of diabetic mice, while mitochondrial biogenesis is downregulated in the skin of diabetic mice. In conclusion, the activation of the UPR, autophagy, and mitochondrial remodeling are crucial for a proper wound healing. These results suggest that the increase in ER stress and autophagy in the skin of diabetic mice at baseline significantly escalated to pathological levels after wounding, contributing to impaired wound healing in diabetes.

Objective: To report the experience of the Portugal Centre For Evidence Based Practice (PCEBP): a JBI Centre of Excellence in the training of health professionals, researchers, and professors in the Comprehensive Systematic Review Training Program, a course on Evidence Synthesis, specifically on Systematic Literature Reviews. Method: This article aims to report the experience of the Portugal Centre For Evidence Based Practice: a JBI Centre of Excellence in the implementation of the Comprehensive Systematic Review Training Program that trains health professionals, researchers, and teachers to develop Systematic Reviews, according to the JBI approach.

As a result of the training of these participants, 13 systematic reviews were published in JBI Evidence Synthesis and 10 reviews were published in other journals. Conclusion: The reported results and the students’ satisfaction evaluation allow us to emphasize the relevance of the course for health professionals training on evidence synthesis.

A series of new asiatic acid derivatives modified in the A-ring and at C-28 were synthesized and their antiproliferative activity was evaluated against HT-29 and HeLa cell lines. Most of the derivatives tested here exhibited improved antiproliferative activity compared with asiatic acid. Among them, the best compounds, 7 and 8, were further evaluated against additional cancer cell lines (MCF-7, Jurkat, and PC-3 cells) and a nontumoral cell line (BJ). The most active compound, 7, exhibited IC 50 values ranging from 1.62 mM in HeLa cells to 9.93 mM in MCF-7 cells. Further studies revealed that compound 7 arrested the cell cycle at the G0/G1 phase and induced caspase-dependent apoptosis in HeLa cells. Furthermore, this compound showed selectivity toward cancer cells, and a synergistic effect was observed after simultaneous treatment of HeLa cells with compound 7 and cisplatin. Collectively, our results suggest that compound 7 may be useful for the development of new anticancer therapies; thus, additional preclinical studies are warranted.
