Understanding the provision of a clinical service in mental health and the role of the pharmacist: a qualitative analysis / Compreendendo a provisão de um serviço clínico na saúde mental e o papel do farmacêutico: uma análise qualitativa / Comprender la prestación de un servicio clínico en salud mental y el papel del farmacéutico: un análisis cualitativo

Pharmacists have important roles in mental health disease; however, their performance in Brazilian Psychosocial Care Centers (CAPS) is unknown. This qualitative study was conducted in a CAPS, Brazil; using interviews and analyzes from the perspective of Bardin, in which categories arising from the perceptions of patients and the health team emerged in relation to the provision of the medication review with follow up (MR) service and the role of the pharmacist in mental health. According to the participants, the MR service is essential and important because it allows professional recognition, beyond the identification of professional attributes of the pharmacists. Moreover, there was a duality in the pharmacist's role between the logistic and clinical attributes of mental health. Thus, this perception helps to elucidate the pharmacist's process of work in mental health and supports future strategies of action in this area. (AU)

Farmacêuticos têm papéis importantes na área da saúde mental; entretanto, sua atuação nos Centros de Atenção Psicossociais (CAPS) brasileiros é desconhecida. Este estudo qualitativo foi realizado em um CAPS, Brasil; utilizando-se de entrevistas e análises sob a perspectiva de Bardin, no qual categorias em relação à prestação do serviço de acompanhamento farmacoterapêutico (AFT) e ao papel do farmacêutico na saúde mental emergiram através das percepções dos pacientes e equipe de saúde. Segundo os participantes, o serviço de AFT é essencial e importante porque permite o reconhecimento profissional, além da identificação dos atributos profissionais dos farmacêuticos. Além disso, houve uma dualidade no papel do farmacêutico em relação aos atributos logísticos e clínicos na saúde mental. Assim, essas percepções ajudam a elucidar o processo de trabalho do farmacêutico em saúde mental, subsidiando futuras estratégias de ação nesta área. (AU)

Los farmacéuticos tienen un papel importante en el área de la salud mental; sin embargo, se desconoce su desempeño en los Centros de Atención Psicosocial de Brasil (CAPS). Este estudio cualitativo se llevó a cabo en un CAPS, Brasil; utilizando entrevistas y análisis desde la perspectiva de Bardin, en las que de las percepciones de los pacientes y del equipo de salud surgieron categorías en relación a la prestación del servicio de seguimento farmacoterapéutico (SFT) y el papel del farmacéutico en la salud mental. Según los participantes, el servicio de SFT es fundamental e importante. Además, existía una dualidad en el rol del farmacéutico en relación a los atributos logísticos y clínicos en salud mental. Así, estas percepciones ayudan a dilucidar el proceso de trabajo del farmacéutico en salud mental, apoyando futuras estrategias de actuación. (AU)

In vivo treatments with fulvestrant and anastrozole differentially affect gene expression in the rat efferent ductules.

Estrogen plays a key role in maintaining the morphology and function of the efferent ductules. We previously demonstrated that the antiestrogen fulvestrant markedly affected gene expression in the rat efferent ductules. The mechanism of fulvestrant action to modulate gene expression may involve not only the blockade of ESR1 and ESR2 estrogen receptors, but also the activation of ESR1 and ESR2 when the receptors are tethered to AP-1 or SP1 transcription factors, or the activation of the G protein-coupled estrogen receptor 1. We therefore compared the effects of two strategies to interfere with estrogen action in the rat efferent ductules: treatment with fulvestrant or with the aromatase inhibitor anastrozole. Whereas fulvestrant markedly increased Mmp7 and Spp1, and reduced Nptx1 mRNA levels, no changes were observed with anastrozole. Fulvestrant caused changes in epithelial morphology that were not seen with anastrozole. Fulvestrant shifted MMP7 immunolocalization in the epithelial cells from the supranuclear to the apical region; this effect was less pronounced with anastrozole. In vitro studies of (35)S-methionine incorporation showed that protein release was increased, whereas tissue protein content in the efferent ductules of fulvestrant-treated rats was decreased. Although fulvestrant markedly affected gene expression, no changes were observed on AP-1 and SP1 DNA-binding activity. The blockade of ESRs seems to be the major reason explaining the differences between both treatments. At least some of the effects of fulvestrant appear to result from compensatory mechanisms activated by the dramatic changes caused by ESR1 blockade.

Estrogen receptors and function in the male reproductive system: [review] / Receptores e função do estrógeno no sistema reprodutor masculino: [revisão]

A substantial advance in our understanding on the estrogen signaling occurred in the last decade. Estrogens interact with two receptors, ESR1 and ESR2, also known as ERα and ERβ, respectively. ESR1 and ESR2 belong to the nuclear receptor family of transcription factors. In addition to the well established transcriptional effects, estrogens can mediate rapid signaling, triggered within seconds or minutes. These rapid effects can be mediated by ESRs or the G protein-coupled estrogen receptor GPER, also known as GPR30. The effects of estrogen on cell proliferation, differentiation and apoptosis are often mediated by growth factors. The understanding of the cross-talk between androgen, estrogen and growth factors signaling pathways is therefore essential to understand the physiopathological mechanisms of estrogen action. In this review we focused on recent discoveries about the nature of the estrogen receptors, and on the signaling and function of estrogen in the male reproductive system.

Durante a última década, ocorreu um avanço substancial no conhecimento da sinalização do estrógeno. Estrógenos interagem com dois receptores, ESR1 e ESR2, também conhecidos como ERα e ERβ, respectivamente. ESR1 e ESR2 pertencem à família de receptores nucleares, que funcionam como fatores de transcrição. Além dos bem estabelecidos efeitos transcricionais, os estrógenos medeiam a sinalização rápida, desencadeada dentro de segundos ou minutos. Esses efeitos rápidos podem ser mediados por ESRs ou pelo receptor de estrógeno acoplado à proteína G, GPER, também conhecido como GPR30. Os efeitos de estrógenos sobre a proliferação celular, diferenciação e apoptose são, muitas vezes, mediados por fatores de crescimento. Portanto, a compreensão da interação entre as vias de sinalização de andrógeno, estrógeno e fatores de crescimento é essencial para entender os mecanismos fisiopatológicos envolvidos na ação estrogênica. Nesta revisão, foram abordadas descobertas recentes sobre a estrutura dos receptores, a sinalização e a função do estrógeno no sistema reprodutor masculino.
