Análisis del conocimiento sobre los inhibidores selectivos de la recaptura de serotonina (ISRS) en el manejo de la depresión por médicos residentes y concurrentes de clínica médica de 5 hospitales de CABA / Review of the Knowledge on Selective Serotonin Reuptake Inhibitors (SSRIs) for Depression Management by Resident and Intern Physicians of the Medical Clinic of 5 Hospitals in CABA

Introducción: la depresión es un trastorno cada vez más prevalente alrededor del mundo. Los médicos generales son los profesionales de la salud más consultados por pacientes deprimidos. Más del 70% de los pacientes con depresión son vistos por médicos generales y no por especialistas en Psiquiatría. Según estudios realizados en Buenos Aires, más del 25% de los pacientes internados en Servicios de Clínica Médica en hospitales generales presenta depresión. Estos pacientes suelen ser atendidos y seguidos por médicos en formación, sean residentes o concurrentes de Clínica Médica. El objetivo del trabajo fue analizar el conocimiento sobre los inhibidores selectivos de la recaptura de serotonina (ISRS) que tienen los médicos residentes y concurrentes de Clínica Médica de 5 hospitales de la Ciudad Autónoma de Buenos Aires (CABA) y describir el tratamiento de un paciente depresivo por ellos. Material y métodos: se realizó un estudio descriptivo de corte transversal con un muestreo de tipo no probabilístico. Se utilizó como instrumento de medición un cuestionario semiestructurado organizado en dos secciones, una de datos demográficos que permiten caracterizar la muestra. La otra, de 15 ítems, explora los conocimientos sobre los ISRS y el tratamiento de la depresión. Dicho cuestionario fue revisado por 4 expertos. El instrumento es anónimo. Se aplicó a 59 médicos en formación en Clínica Médica, residentes y concurrentes, de 5 hospitales de la CABA, que participaron de forma voluntaria, durante el período agosto-septiembre de 2022. Resultados: la mayoría de los médicos en formación en Clínica Médica no tratan cuadros depresivos y, ante un paciente deprimido, solicitan la evaluación por un especialista en Salud Mental. Solo un 6,8% lo medica con un antidepresivo. Más del 75% de la muestra refiere recordar los conocimientos que tiene sobre de los ISRS de la cursada de Farmacología y un 13,6 de la cursada de Psiquiatría en la Facultad de Medicina. Conclusión: se observa un conocimiento deficitario sobre los ISRS en médicos residentes y concurrentes de Clínica Médica. Se considera necesario reforzar la formación sobre depresión y manejo de antidepresivos durante la residencia/concurrencia de Clínica Médica. (AU)

Introduction: depression is an increasingly common disorder around the world. General practitioners are the most frequently consulted health professionals by depressed patients. More than 70% of all depressed patients receive treatment by general practitioners and not by psychiatric specialists. According to studies conducted in Buenos Aires, more than 25% of all patients admitted to the Clinical Services in public hospitals present depression. These patients are usually under the care and follow-up of clinical trainee physicians, residents, or interns.This study aimed to analyze the knowledge about selective serotonin reuptake inhibitors (SSRIs) of clinical trainee residents and interns in five hospitals in the Ciudad Autónoma de Buenos Aires (CABA) and to describe their treatment of a depressive patient. Material and methods: we conducted a descriptive cross-sectional study with a non-probabilistic sampling. We used a semi-structured questionnaire arranged into two sections as a measuring tool. One, with demographic data to describe the sample. The other, with 15 items, explores respondents' knowledge of SSRIs and the treatment of depression. Four experts reviewed the questionnaire, which was anonymous. We applied it to 59 clinical medical trainees, residents, and interns from five CABA hospitals who volunteered to participate during August-September 2022. Results: most clinical trainees do not treat depressive conditions and, when confronted with a depressed patient, request an assessment by a Mental Health specialist. Only 6.8% medicate the patient with an antidepressant. More than 75% of the sample reported remembering their knowledge of SSRIs from the Pharmacology course and 13.6% from the Psychiatry course at the School of Medicine. Conclusion: there is a deficient knowledge about SSRIs in trainee residents and interns of Clínica Médica. We believe it is necessary to reinforce training on depression and management of antidepressants during residency/internship practice in Clínica Médica. (AU)

Avaliação da incidência de uso de antidepressivos em estudantes de medicina do estado de Alagoas / Evaluation of the incidence of antidepressant use among medical students in the state of Alagoas

O presente estudo objetivou determinar a frequência do uso de antidepressivos entre os estudantes de Medicina do Estado de Alagoas, dessa forma, consiste em um estudo prospectivo e transversal, realizado nas instituições de ensino superior do Estado de Alagoas possuidoras da graduação de Medicina. Critérios de inclusão foram estar matriculado e frequentando o curso, cursando do primeiro ao quarto ano e possuir 18 anos ou mais. Já os critérios de exclusão foram ser do quinto ou sexto ano de graduação; possuir idade menor que 18 anos, mesmo que emancipado. Através de questionário autopreenchido (informações sociodemográficas, estilo de vida e inventário de Ansiedade de Beck), foram entrevistados 342 acadêmicos de forma aleatória. Os dados adquiridos foram digitados, tabulados e analisados. Este estudo teve aprovação do Comitê de Ética em Pesquisa. Todos os participantes leram e assinaram o Termo de Consentimento Livre e Esclarecido em conformidade aos critérios da resolução 466/12. Dos entrevistados, 15% recorrem a antidepressivo e 85% não fazem uso desse tipo de fármaco. Mesmo dando uma percentagem baixa, ainda é preocupante e bastante importante abordar sempre esse tema e reformular o ensino médico, de modo a diminuir os níveis de estresse e ansiedade dos estudantes (AU).

This study aimed to determine the frequency of antidepressant use among medical students in the State of Alagoas, thus consisting of a prospective and cross-sectional study carried out in higher education institutions in the State of Alagoas that offer undergraduate medical education. Inclusion criteria were being enrolled and attending the course, from the first to the fourth year, and being 18 years old or older. The exclusion criteria were being in the fifth or sixth year of medical school; being younger than 18 years old, even if emancipated. Through a self-completed questionnaire (sociodemographic information, lifestyle, and Beck's Anxiety Inventory), 342 students were randomly interviewed. The data were typed, tabulated and analyzed. This study was approved by the Research Ethics Committee. All participants who participated read and signed the Informed Consent Form according to the criteria of resolution 466/12. Fifteen percent of the respondents use antidepressants and 85% do not use this type of drug. Even giving a low percentage, it is still worrisome and quite important to always address this issue and reformulate medical education in order to decrease the levels of stress and anxiety among students (AU).

Sentimentos e percepções do luto de sobreviventes ao suicídio de jovens / Feelings and perceptions of grief among survivors of youth suicide / Sentimientos y percepciones de duelo entre sobrevivientes de suicidio de jóvenes

Sobreviventes ao suicídio são pessoas que têm suas vidas profundamente afetadas e apresentam sofrimento psicológico, físico ou social após serem expostas a esse fato. O objetivo deste estudo foi analisar a experiência de sobreviventes ao suicídio de jovens, a partir do luto. Participaram sete sobreviventes entre familiares, amigos e parceiros amorosos de jovens que cometeram suicídio. A análise de conteúdo de entrevistas narrativas apontou que os participantes utilizam explicações racionalizadas ou dissociadas, criando uma distância entre o evento e eles mesmos. Como formas de lidar com o sofrimento podem buscar o isolamento, apoio entre amigos, prática religiosa e/ou a dedicação ao trabalho. Reafirma-se a dimensão do luto diante dessa experiência, além da importância da prevenção ao suicídio e da posvenção aos sobreviventes.(AU)

Suicide survivors are people who have their lives deeply affected; they experience psychological, physical, and social suffering following the occurrence. The aim of this study is to analyze the experience of survivors of youth suicide attempts, based on grief. Seven survivors participated among family, friends, and romantic partners of young people who committed suicide. The content analysis of narrative interviews showed that the participants use rationalized or dissociated explanations, creating a distance between the event and themselves. As ways to deal with suffering, they seek isolation, support among friends, religious practice, and/or dedication to work. The dimension of grief in the face of this experience is reaffirmed, as well as the importance of suicide prevention and postvention for survivors.(AU)

Este artículo tiene como objetivo presentar la construcción metodológica desarrollada en una investigación de maestría, en la que sostenemos la escritura de escenas como método de investigación de la escucha clínica. Las escenas del trabajo en cuestión se recogieron a lo largo del tiempo desde la experiencia en un proyecto de extensión universitario de atención a la niñez y adolescencia en situación de vulnerabilidad social aplicado en una comunidad periférica. En este texto, presentamos los interrogantes que se elaboraron en torno a la elección por el trabajo con escenas y compartimos el rescate histórico de las mismas como un método de escribir la clínica y la reanudación del análisis a partir de la tradición psicoanalítica. Amparadas en el psicoanálisis y en lecturas y contribuciones del filósofo francés Jacques Derrida, nos basaremos en la noción de que la escena se constituye como un lugar de producción, engendrando la configuración particular de elementos significantes en los procesos de subjetivación y de construcción social. La escena no es aquí una representación de lo que pasa en la clínica, sino un modo de producir escucha y sus procesos de investigación.(AU)

Comparison of mouse models of depression induced by different modeling methods / 生理学报

The present article was aimed to compare the effectiveness of different induction methods for depression models. Kunming mice were randomly divided into chronic unpredictable mild stress (CUMS) group, corticosterone (CORT) group, and CUMS+CORT (CC) group. The CUMS group received CUMS stimulation for 4 weeks, and the CORT group received subcutaneous injection of 20 mg/kg CORT into the groin every day for 3 weeks. The CC group received both CUMS stimulation and CORT administration. Each group was assigned a control group. After modeling, forced swimming test (FST), tail suspension test (TST) and sucrose preference test (SPT) were used to detect the behavioral changes of mice, and the serum levels of brain-derived neurotrophic factor (BDNF), 5-hydroxytryptamine (5-HT) and CORT were detected with ELISA kits. Attenuated total refraction (ATR) spectra of mouse serum were collected and analyzed. HE staining was used to detect morphological changes in mouse brain tissue. The results showed that the weight of model mice from the CUMS and CC groups decreased significantly. There was no significant change in immobility time of model mice from the three groups in FST and TST, while the glucose preference of model mice from the CUMS and CC groups was significantly reduced (P < 0.05). The serum 5-HT levels of model mice from the CORT and CC groups were significantly reduced, while the serum BDNF and CORT levels of model mice from the CUMS, CORT, and CC groups showed no significant changes. Compared with their respective control groups, the three groups showed no significant difference in the one-dimensional spectrum of serum ATR. The difference spectrum analysis results of the first derivative of the spectrogram showed that the CORT group had the greatest difference from its respective control group, followed by the CUMS group. The structures of hippocampus in the model mice from the three groups were all destroyed. These results suggest that both CORT and CC treatments can successfully construct a depression model, and the CORT model is more effective than the CC model. Therefore, CORT induction can be used to establish a depression model in Kunming mice.

Anxiolytic and antidepressant effects of agarwood inhalation and its mechanism / 中国中药杂志

This study used m-chloropheniperazine(MCPP) and chronic unforeseeable mild stress(CUMS) to induce the rat models of anxiety and depression, respectively. The behaviors of rats were observed by the open field test(OFT), light-dark exploration test(LDE), tail suspension test(TST), and forced swimming test(FST), and the antidepressant and anxiolytic effects of agarwood essential oil(AEO), agarwood fragrant powder(AFP), and agarwood line incense(ALI) were explored. The enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of 5-hydroxytryptamine(5-HT), glutamic acid(Glu), and γ-aminobutyric acid(GABA_A) in the hippocampal area. The Western blot assay was used to determine the protein expression levels of glutamate receptor 1(GluR1) and vesicular glutamate transporter type 1(VGluT1), exploring the anxiolytic and antidepressant mechanism of agarwood inhalation. The results showed that compared with the anxiety model group, the AEO, AFP, and ALI groups decreased the total distance(P<0.05), decreased the velocity of movements(P<0.05), prolonged the immobile time(P<0.05), and reduced the distance and velocity of the rat model of anxiety in the dark box(P<0.05). Compared with the depression model group, the AEO, AFP, and ALI groups increased the total distance and average velocity(P<0.05), reduced the immobile time(P<0.05), and reduced the forced swimming and tail suspension time(P<0.05). In terms of transmitter regulation, the AEO, AFP, and ALI groups decreased the level of Glu in the rat model of anxiety(P<0.05) and increased the levels of GABA_A and 5-HT(P<0.05), while the AEO, AFP, and ALI groups all increased the level of 5-HT in the rat model of depression(P<0.05) and decreased the levels of GABA_A and Glu(P<0.05). At the same time, the AEO, AFP, and ALI groups all increased the protein expression levels of GluR1 and VGluT1 in the hippocampus of the rat models of anxiety and depression(P<0.05). In conclusion, AEO, AFP, and ALI exert anxiolytic and antidepressant effects, and the mechanism might be related to the regulation of the neurotransmitter and the protein expression of GluR1 and VGluT1 in the hippocampus.

Baicalin Ameliorates Corticosterone-Induced Depression by Promoting Neurodevelopment of Hippocampal via mTOR/GSK3β Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the role of hippocampal neurodevelopment in the antidepressant effect of baicalin.@*METHODS@#Forty male Institute of Cancer Research mice were divided into control, corticosterone (CORT, 40 mg/kg), CORT+baicalin-L (25 mg/kg), CORT+baicalin-H (50 mg/kg), and CORT+fluoxetine (10 mg/kg) groups according to a random number table. An animal model of depression was established by chronic CORT exposure. Behavioral tests were used to assess the reliability of depression model and the antidepressant effect of baicalin. In addition, Nissl staining and immunofluorescence were used to evaluate the effect of baicalin on hippocampal neurodevelopment in mice. The protein and mRNA expression levels of neurodevelopment-related factors were detected by Western blot analysis and real-time polymerase chain reaction, respectively.@*RESULTS@#Baicalin significantly ameliorated the depressive-like behavior of mice resulting from CORT exposure and promoted the development of dentate gyrus in hippocampus, thereby reversing the depressive-like pathological changes in hippocampal neurons caused by CORT neurotoxicity. Moreover, baicalin significantly decreased the protein and mRNA expression levels of glycogen synthase kinase 3β (GSK3β), and upregulated the expression levels of cell cycle protein D1, p-mammalian target of rapamycin (mTOR), doublecortin, and brain-derived neurotrophic factor (all P<0.01). There were no significant differences between baicalin and fluoxetine groups (P>0.05).@*CONCLUSION@#Baicalin can promote the development of hippocampal neurons via mTOR/GSK3β signaling pathway, thus protect mice against CORT-induced neurotoxicity and play an antidepressant role.

Meranzin Hydrate Improves Depression-Like Behaviors and Hypomotility via Ghrelin and Neurocircuitry / 中国结合医学杂志

OBJECTIVE@#To investigate whether meranzin hydrate (MH) can alleviate depression-like behavior and hypomotility similar to Chaihu Shugan Powder (CSP), and further explore the potential common mechanisms.@*METHODS@#Totally 120 Spraque-Dawley rats were randomly divided into 5-8 groups including sham, vehicle, fluoxetine (20 mg/kg), mosapride (10 mg/kg), CSP (30 g/kg), MH (9.18 mg/kg), [D-Lys3]-GHRP-6 (Dlys, 0.5 mg/kg), and MH+Dlys groups by a random number table, 8 rats in each group. And 32 mice were randomly divided into wild-type, MH (18 mg/kg), growth hormone secretagogue receptor-knockout (GHSR-KO), and GHSR+MH groups, 8 mice in each group. The forced swimming test (FST), open field test (OFT), tail suspension test (TST), gastric emptying (GE) test, and intestinal transit (IT) test were used to assess antidepressant and prokinetic (AP) effects after drug single administration for 30 min with absorbable identification in rats and mice, respectively. The protein expression levels of brain-derived neurotrophic factor (BDNF) and phosphorylated mammalian target of rapamycin (p-mTOR) in the hippocampus of rats were evaluated by Western blot. The differences in functional brain changes were determined via 7.0 T functional magnetic resonance imaging-blood oxygen level-dependent (fMRI-BOLD).@*RESULTS@#MH treatment improved depression-like behavior (FST, OFT) and hypomotility (GE, IT) in the acute forced swimming (FS) rats (all P<0.05), and the effects are similar to the parent formula CSP. The ghrelin antagonist [D-Lys3]-GHRP-6 inhibited the effect of MH on FST and GE (P<0.05). Similarly, MH treatment also alleviated depression-like behavior (FST, TST) in the wild-type mice, however, no effects were found in the GHSR KO mice. Additionally, administration of MH significantly stimulated BDNF and p-mTOR protein expressions in the hippocampus (both P<0.01), which were also prevented by [D-Lys3]-GHRP-6 (P<0.01). Besides, 3 main BOLD foci following acute FS rats implicated activity in hippocampus-thalamus-basal ganglia (HTB) circuits. The [D-Lys3]-GHRP-6 synchronously inhibited BOLD HTB foci. As expected, prokinetic mosapride only had effects on the thalamus and basal ganglia, but not on the hippocampus. Within the HTB, the hippocampus is implicated in depression and FD.@*CONCLUSIONS@#MH accounts for part of AP effects of parent formula CSP in acute FS rats, mainly via ghrelin-related shared regulation coupled to BOLD signals in brain areas. This novel functionally connection of HTB following acute stress, treatment, and regulation highlights anti-depression unified theory.

Antidepressant mechanism of Shenling Kaixin Granules based on BDNF/TrkB/CREB pathway / 中国中药杂志

To investigate the antidepressant mechanism of Shenling Kaixin Granules(SLKX) in treating chronic unpredictable mild stress(CUMS) model rats. Ninety male SD rats were randomly divided into control group, model group, Shugan Jieyu Capsules(110 mg·kg~(-1)) group and SLKX low-(90 mg·kg~(-1)), medium-(180 mg·kg~(-1)), and high-dose(360 mg·kg~(-1)) groups. Depression rat model was replicated by CUMS method. After treatment, the behavioral changes of rats were evaluated by sugar preference, open field, elevated cross maze and forced swimming experiments. The contents of interleukin 1 beta(IL-1β), tumor necrosis factor α(TNF-α), brain-derived neurotrophic factor(BDNF) and 5-hydroxytryptamine(5-HT) in serum were determined by enzyme linked immunosorbent assay(ELISA), and the activities of superoxide dismutase(SOD) and catalase(CAT) in hippocampal CA1 region were also detected. Pathological changes in hippocampal CA1 region were detected by hematoxylin-eosin(HE) staining, and Western blot was used to determine the expression of nerve growth factor(NGF), BDNF, phospho-tyrosine kinase receptor(p-TrkB)/TrkB, phospho-cAMP-response element binding protein(p-CREB)/CREB, nuclear factor E2 related factor 2(Nrf2), heme oxygenase 1(HO-1), B-cell lymphoma-2(Bcl-2)/Bcl-2 associated X protein(Bax) and caspase-3 in hippocampal CA1 region. RESULTS:: showed that compared with the control group, the model group had decreased sugar preference, reduced number of entries and time spent in the center of open field and shortened total distance of movement, reduced number of entries and proportion of time spent in open arm, and increased number and time of immobility in forced swimming experiment. Additionally, the serum contents of IL-1β and TNF-α and the expression of caspase-3 were higher, while the contents of BDNF and 5-HT, the activities of SOD and CAT in hippocampal CA1 region, the expressions of NGF, BDNF, p-TrkB/TrkB, p-CREB/CREB, HO-1 and Bcl-2/Bax, and the Nrf2 nuclear translocation were lower in model group than in control group. Compared with the conditions in model group, the sugar preference, the number of entries and time spent in the center of open, total distance of movement, and the number of entries and proportion of time spent in open arm in treatment groups were increased while the number and time of immobility in forced swimming experiment were decreased; the serum contents of IL-1β and TNF-α and the expression of caspase-3 were down regulated, while the contents of BDNF and 5-HT, the activities of SOD and CAT in hippocampal CA1 region, the expressions of NGF, BDNF, p-TrkB/TrkB, p-CREB/CREB, HO-1, Bcl-2/Bax, and Nrf2 nuclear translocation were enhanced. In conclusion, SLKX might regulate the Nrf2 nucleus translocation by activating BDNF/TrkB/CREB pathway, lower oxidative stress damage in hippocampus, inhibit caspase-3 activity, and reduce apoptosis of hippocampal nerve cells, thereby playing an antidepressant role.

Diretrizes clínicas para tratamento da depressão: análise de fatores associados à qualidade e comparação de recomendações para pacientes não respondedores e com depressão resistente / Clinical guidelines for the treatment of depression: analysis of factors associated with quality and comparison of recommendations for nonresponding patients and for patients with resistant depression

Diretrizes clínicas (DCs) de alta qualidade são importantes para a assistência efetiva de pacientes com doenças crônicas, incluindo a depressão. A depressão é um dos principais problemas de saúde mundial, sendo um dos transtornos psiquiátricos mais comumente encontrados na prática médica, afetando cerca de 300 milhões de pessoas. Além de sua natureza debilitante e onerosa, muitas vezes pode levar a desfechos graves, tal como o suicídio, principalmente em pacientes que não respondem aos tratamentos. Assim, o objetivo geral desta tese foi identificar fatores das DCs associados à qualidade metodológica desses documentos e de suas recomendações, e comparar as recomendações para duas situações de falhas da farmacoterapia: pacientes não respondedores e pacientes com depressão resistente ao tratamento (DRT). Operacionalmente, foram feitas revisões sistemáticas da literatura em bases científicas e específicas de DCs, e incluídas DCs publicadas nos últimos onze anos que contivessem recomendações para o tratamento farmacológico de adultos com depressão. Para avaliação geral das DCs, foi aplicado o instrumento AGREE II, e para avaliação específica das recomendações, o instrumento AGREE-REX. As DCs foram consideradas de alta qualidade quando pontuaram com escores maiores ou iguais a 60% (no estudo descrito no capítulo 2) e maiores ou iguais a 80% (no estudo descrito no capítulo 3) no domínio 3 (Rigor de desenvolvimento) do AGREE II. As DCs com recomendações de alta qualidade foram as que pontuaram com mais de 60% no domínio 1 (Aplicabilidade Clínica) do AGREE-REX. Das 63 DCs selecionadas, 17 (27%) apresentaram alta qualidade, e 7 (11%) apresentaram recomendações de alta qualidade. Os fatores associados à maior qualidade foram gerenciamento de conflitos de interesses, equipe multiprofissional e tipo de instituição. A inclusão de representante do paciente na equipe também foi associada a recomendações de maior qualidade. Verificou-se que a maioria das DCs concorda com a necessidade de: reavaliar o diagnóstico, a presença de comorbidades, a adesão ao tratamento, ajustar a dosagem do antidepressivo e adicionar psicoterapia como os primeiros passos para aqueles que não respondem ao tratamento antidepressivo de primeira linha. Em relação às recomendações, há falhas importantes, incluindo a não apresentação de definição padronizada de resposta adequada/inadequada/parcial, e o não estabelecimento de tempo de tratamento necessário para declarar DRT. Todas as DCs incluíram a possibilidade de substituição do antidepressivo, potencialização com outros medicamentos e combinação de antidepressivos. Todavia, três DCs não recomendaram uma sequência entre eles. Por fim, verificou-se que das 17 DCs de alta qualidade e das 7 DCs com recomendações de alta qualidade, apenas duas incluíram definição e recomendações para DRT. Não existe consenso entre as DCs de alta qualidade quanto à definição e uso do termo DRT. Não foi possível extrair uma estratégia terapêutica convergente para DRT em adultos. Os resultados obtidos reforçam a necessidade de maior foco no aprimoramento da qualidade das DCs e de suas recomendações, especialmente nos subgrupos relativos à resposta inadequada ao tratamento e a DRT, nas quais as definições não são claras

High-quality clinical practice guidelines (CPGs) are important for treating patients with chronic diseases such as depression. Depression is a major health concern worldwide, affecting approximately 300 million people. It is one of the most prevalent psychiatric disorders in medical practice. It is not only debilitating and costly but can also lead to tragic consequences such as suicide, particularly in patients who do not respond to treatment. The objective of this thesis was to identify CPGs factors associated with the methodological quality of these documents and their recommendations. Furthermore, this thesis aimed to compare the recommendations in two pharmacotherapy failure situations: inadequate response to treatment and treatment-resistant depression (TRD). Systematic literature reviews were conducted on scientific and CPG-specific databases. Reviews were also conducted on CPGs published in the last eleven years that included recommendations for pharmacological treatment of adults with depression. The AGREE II instrument was used for the CPGs general assessment, while the AGREE-REX instrument was used specifically to assess their recommendations. CPGs were considered high quality if they achieved a score of at least 60% in the study mentioned in Chapter 2 and a score of at least 80% in the study mentioned in Chapter 3 in the AGREE II, rigour of development domain. The CPGs with high-quality recommendations were those that scored greater than 60% in Domain 1 (Clinical Applicability) of the AGREE-REX. Of the 63 selected CPGs, 17 (27%) were high quality, and 7 (11.1%) had recommendations of high quality. Factors associated with higher quality were conflict of interest management, multi-professional team, and type of institution. Inclusion of a patients representative on the team was associated with higher quality recommendations. Most CPGs agreed with the need to reassess diagnoses, comorbidities, and treatment adherence. They also agreed on adjusting antidepressant dosage and providing psychotherapy as a first step for patients who do not respond to first-line antidepressant treatment. There are significant shortcomings in the recommendations. In particular, the lack of a standardized definition of adequate, inadequate, or partial response to treatment and the lack of clarity surrounding the duration of treatment required to establish TRD. All CPGs included the possibility of antidepressant substitution, potentiation with other drugs, and a combination of antidepressants. However, three CPGs did not recommend a preferred sequence for these interventions. Finally, of the 17 high-quality CPGs and the 7 CPGs with high-quality recommendations, only two included definition and recommendations for TRD. There is no consensus among the high-quality CPGs regarding the definition and use of the term TRD. Ultimately, finding a convergent therapeutic strategy for TRD in adults was not possible. These results highlighted the need to focus more on improving the quality of CPGs and their recommendations, especially in the subgroups related to inadequate response to treatment and TRD, where definitions are unclear

Situação-limite: por outro olhar sobre a violência em um Caps AD / Limit-situation: for another look on the violence in a CAPS AD / Situación límite: otra mirada sobre la violencia en un Caps AD

Este relato de experiência, situado no campo do cuidado a pessoas usuárias de álcool e outras drogas em contextos marcados por violência, tem como objetivo explorar os limites, desafios e caminhos possíveis, em um Centro de Atenção Psicossocial Álcool e Drogas (Caps AD III), para a sustentação de um cuidado orientado pela compreensão das pessoas usuárias do Caps a partir da sua existência, sofrimento e relação com o corpo social, mesmo diante de comportamentos tidos como violentos. De caráter qualitativo, o percurso de pesquisa foi conduzido por meio de dois recursos metodológicos: o relato de experiência, referente à trajetória de uma das autoras no Programa de Residência Multiprofissional em Saúde Mental do Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro (IPUB/UFRJ), e a metodologia caso traçador ou usuário-guia. O trabalho de cuidar de pessoas expostas à necropolítica exige um posicionamento ético dos trabalhadores de saúde mental de engendrar processos de resistências e produção de vida. Pela radicalidade que é vivenciá-la, a violência comparece como um elemento dificultador desse trabalho para os profissionais, fazendo com que, diante do desamparo, por vezes utilizem lógicas disciplinares para conseguir lidar com esse fenômeno. Propõe-se abordar as cenas nomeadas como violentas nos Caps com base na noção de situação-limite, retirando a situação da malha de sentidos que acompanha a palavra e remete a práticas disciplinares e ao contexto da violência urbana. Essa mudança de paradigma abre a possibilidade de que os trabalhadores se incluam nas situações, as entendam como relacionadas à complexidade e à singularidade da existência das pessoas envolvidas e, assim, proponham soluções produtoras de vida.(AU)

This experience report, situated in the field of care for people who use alcohol and other drugs in contexts marked by violence, aims to explore the limits, challenges, and possible paths, at a Psychosocial Care Center for Alcohol and Drugs (CAPS AD III), to support care guided by the knowledge of CAPS users based on their existence, suffering, and relationship with the social body, even in the face of behaviors considered to be violent. The path of this qualitative research was conducted with two methodological resources: the experience report, referring to the trajectory of one of the authors at the Multiprofessional Residency Program in Mental Health at the Institute of Psychiatry at the Federal University of Rio de Janeiro (IPUB/UFRJ), and the methodology of case tracer or user-guide. The work of caring for people exposed to necropolitics requires an ethical positioning of mental health workers to build resistance processes and life production. Due to it is radical to experience, violence appears as a complicating element of this work for the professionals, forcing them to, due to the lack of support, occasionally use disciplinary reasoning to deal with this phenomenon. This study proposes to approach violent scenarios in the CAPS under the guise of limit-situation, withdrawing the situation from the web of meanings that accompany the word and refer to disciplinary actions and the context of urban violence. This paradigmatic change opens the path for workers to include themselves in these situations, to understand their relationship with the complexity and singularity of the existence of the implicated people, and thus offer solutions that produce life.(AU)

Este reporte de experiencia se sitúa en el área de la atención a las personas que consumen alcohol y otras drogas en contexto de violencia y tiene por objetivo explorar los límites, desafíos y caminos posibles en un Centro de Atención Psicosocial Alcohol y Drogas (Caps AD III), para ofrecer un cuidado a los usuarios basado en la comprensión de las personas usuarias del Caps considerando su existencia, sufrimiento y relación con el cuerpo social, incluso ante situaciones violentas. Esta es una investigación cualitativa que se basó en dos recursos metodológicos: el reporte de experiencia sobre la trayectoria de una de las autoras en el Programa de Residencia Multiprofesional en Salud Mental de la Universidad Federal de Río de Janeiro (IPUB/UFRJ) y de la metodología del caso trazador o usuario guía. La labor de asistir a las personas expuestas a la necropolítica requiere un posicionamiento ético de los profesionales de la salud mental de producir vida y procesos de resistencia. Por la radicalidad de la experiencia, la violencia es un obstáculo para el trabajo de los profesionales, lo que los llevan a actuar de forma disciplinaria para hacer frente a este fenómeno. Se propone aquí abordar las escenas violentas bajo la noción de situación límite en el Caps, sacando del contexto la red semántica que acompaña la palabra y alude a las prácticas disciplinarias y la violencia urbana. Este cambio de paradigma permite que los trabajadores se incluyan en las situaciones, las comprendan en relación con la complejidad y la singularidad de la existencia de las personas y propongan soluciones que produzcan vida.(AU)

Plantas com ação no sistema nervoso central que constam na relação nacional de plantas medicinais de interesse ao sus (RENISUS) / Plants acting on the central nervous system: review plantas com ação no sistema nervoso central que constam na relação nacional de plantas medicinais de interesse ao sus (RENISUS) / Plantas con acción sobre el sistema nervioso central incluidas en la lista nacional de plantas medicinales de interés para sus (RENISUS)

A depressão é uma doença grave que atinge a população em geral, estudos epidemiológicos estimam que a prevalência da depressão ao longo da vida no Brasil está em torno de 15,5%. Os fatores que desencadeiam o aparecimento da depressão incluem fatores sociais, psicológicos, biológicos e também fatores externos específicos como eventos estressantes, solidão, consumo de álcool e drogas, doenças crônicas e dar á luz (depressão pós-parto). O objetivo da presente pesquisa consistiu em realizar uma revisão bibliográfica sobre as principais plantas medicinais com ação antidepressiva. A ansiedade vem se tornando um dos principais problemas da atualidade, sendo intensificada pela pandemia causada pelo coronavírus, onde constatou-se que durante o pico da pandemia onde os casos confirmados de COVID-19 no Brasil ascenderam de 45.757 para 330.890, e as mortes, de 2.906 para 21.048, o sentimento de tristeza/depressão atingiu 40% dos adultos brasileiros. Os sintomas de depressão podem ser amenizados quando a disponibilidade sináptica de monoaminas são aumentadas, e esse aumento pode ocorrer através da diminuição da metabolização desses neurotransmissores. Neste sentido, busca-se através da farmacoterapia a utilização de antidepressivos que disponibilizem as monoaminas na fenda sináptica. A escolha do fármaco é feita com base nos sintomas da depressão e na boa resposta a uma determinada classe de antidepressivos. Em fevereiro de 2009 o Ministério da saúde lançou a Relação Nacional de Plantas Medicinais de Interesse ao SUS (RENISUS), contendo 71 espécies vegetais que são distribuídas de forma in natura nas unidades básicas de saúde (UBS). Destas, somente três espécies apresentam efeito antidepressivo e ansiolítico comprovados na literatura sendo Matricharia chamomilla, Erytrinum mulungu e a Passiflora incarnata que também fazem parte da RENISUS. Além destas, outras espécies como a Melissa officinalis, Lippia alba, Valeriana officinalis e Piper methysticum são utilizadas pela população para tratar ansiedade, insônia e depressão, sugerindo desta forma que estas espécies sejam incluídas na RENISUS.

Depression is a serious disease that affects the general population, epidemiological studies estimate that the prevalence of depression throughout life in Brazil is around 15.5%. The factors that trigger the onset of depression include social, psychological, biological and also specific external factors such as stressful events, loneliness, alcohol and drug consumption, chronic diseases and giving birth (postpartum depression). The objective of the present research was to carry out a literature review on the main medicinal plants with antidepressant action. Anxiety has become one of the main problems of today, being intensified by the pandemic caused by the coronavirus, where it was found that during the peak of the pandemic where confirmed cases of COVID-19 in Brazil rose from 45,757 to 330,890, and deaths, from 2,906 to 21,048, the feeling of sadness/depression reached 40% of Brazilian adults. Symptoms of depression can be alleviated when synaptic availability of monoamines is increased, and this increase can occur through decreased metabolization of these neurotransmitters. In this sense, the use of antidepressants that make monoamines available in the synaptic cleft is sought through pharmacotherapy. The choice of drug is based on symptoms of depression and good response to a particular class of antidepressants. In February 2009, the Ministry of Health launched the National List of Medicinal Plants of Interest to the SUS (RENISUS), containing 71 plant species that are distributed in natura form in basic health units (UBS). Of these, only three species have antidepressant and anxiolytic effects proven in the literature, being Matricharia chamomilla, Erytrinum mulungu and Passiflora incarnata, which are also part of RENISUS. In addition to these, other species such as Melissa officinalis, Lippia alba, Valeriana officinalis and Piper methysticum are used by the population to treat anxiety, insomnia and depression, thus suggesting that these species are included in RENISUS.

Combinación de antidepresivos vs. aumentación con antipsicóticos atípicos tras no lograr la remisión en la depresión unipolar / Combination of antidepressants vs. augmentation with atypical antipsychotics upon failure to achieve remission in unipolar depression

RESUMEN: Introducción: Lograr la recuperación funcional lo más rápido posible en el tratamiento de la depresión unipolar es un reto que la práctica clínica debe tratar de afrontar en la actualidad, ya que cualquier retraso en lograr la remisión de los síntomas es predictivo de un mayor número de recurrencias y mayores tasas de morbimortalidad. En esta revisión comprensiva, nuestro objetivo es guiar a los clínicos en su elección de aumentar con antipsicóticos atípicos o combinar el fármaco de referencia con un segundo antidepresivo, después de que se haya optimizado la dosis del antidepresivo seleccionado inicialmente y/o se haya cambiado el antidepresivo, sin lograr remisión, o bien cuando solo han obtenido una respuesta parcial después de un tiempo suficiente a una dosis apropiada. Estas decisiones surgen con frecuencia en la práctica clínica diaria. Metodología: Se realizó una búsqueda sistemática en PubMed bajo varias combinaciones clave de palabras, resultando en 230 informes. Después de aplicar los criterios de inclusión y según el título y el resumen, el número final de informes seleccionados para la revisión completa fue de 113. Se respondieron dos preguntas principales con base en estos estudios: 1) ¿Existe evidencia para recomendar claramente la combinación de antidepresivos versus potenciación con antipsicóticos (y el momento correcto para hacerlo) en la depresión unipolar no respondedora, una vez que las estrategias de optimización o de cambio han fallado en obtener la remisión? y 2) ¿Es posible identificar algunas características clínicas para guiar la decisión de combinación de antidepresivos versus potenciación con agentes antipsicóticos? Resultados: Según nuestro análisis, no hay datos disponibles para seleccionar una estrategia de otra de manera clara. Sin embargo, sugerimos favorecer una combinación o estrategia de aumento, basada en un enfoque de "tratamiento contra objetivos dianas" para perfilar al paciente, considerando una o dos características clínicas predominantes que permanecen activas como parte de una depresión mayor con respuesta parcial. Un adecuado análisis de los dominios sintomáticos presentes, una visión crítica de las guías clínicas actuales y de las opciones preferidas, considerar la bipolaridad oculta como uno de los principales diagnósticos diferenciales y adoptar una actitud enérgica pero lúcida en esta etapa del tratamiento son, a nuestro juicio, fundamentales para lograr recuperación ad integrum del paciente.

ABSTRACT Introduction: achieving functional recovery as quickly as possible in the treatment of unipolar depression is a challenge that clinical practice must try to meet nowadays, since any delay in accomplishing remission of the symptoms is predictive of a larger number of recurrences and higher morbidity and mortality rates. In this topical review we aim to guide clinicians in their choice to augment with atypical antipsychotics or to combine the baseline drug with a second antidepressant, after the dose of the antidepressant initially selected has been optimized and/or the antidepressant has been changed, not achieving remission, or resulting only in a partial response after sufficient time at an appropriate dose. These decisions arise frequently in everyday clinical practice. Methodology: a systematic search in PubMed was performed under several key combinations of words, resulting in 230 reports. After applying inclusion criteria and based in title and abstract, the final number of reports selected for full revision were 113. Two main questions were answered based on these studies: 1) Is there evidence to clearly recommend combination of antidepressants vs. augmentation with antipsychotics (and the correct moment to do it) in non-responsive unipolar depression, once optimization or switching strategies have failed to obtain remission? and 2) Is it possible to identify some clinical features to guide the decision of combination of antidepressants vs. augmentation with antipsychotic agents? Results: According to our analysis, there is no data available to select one strategy from another in a clear-cut manner. Nevertheless, we suggest favoring a combination or augmentation strategy, based in a "treating to target" approach to profile the patient, considering one or two predominant clinical features that remain active as part of a major depression with partial response. Proper analysis of the symptomatic domains present, a critical view of current clinical guidelines and preferred options, considering hidden bipolarity as one of the main differential diagnoses and adopting an energetic but lucid attitude at this stage of treatment are, in our view, fundamental for achieving ad integrum patient recovery.

Estudio retrospectivo de pacientes intoxicados admitidos en la unidad de cuidados intensivos pediátricos de un hospital en Chile / Retrospective study of poisoned patients admitted to a hospital's pediatric intensive care unit in Chile

Introducción. Las intoxicaciones pediátricas son un problema de salud pública a nivel mundial. El objetivo de este estudio fue caracterizar las intoxicaciones pediátricas que fueron atendidas en la unidad de cuidados intensivos pediátricos (UCIP) de un hospital en Chile. Población y métodos. Se revisaron las fichas clínicas de pacientes diagnosticados con intoxicación e ingresados a la UCIP entre los años 2013 y 2017. Resultados. Un total de 105 casos fueron identificados, lo que representa un 3 % del total de ingresos registrados en el período estudiado. La mediana de edad de los pacientes resultó ser de 10 años. El 73,3 % de los casos correspondieron a pacientes de sexo femenino. El 51 % de los casos se asociaron a intoxicaciones intencionales y el 83 % fue causado por exposición a medicamentos. Los medicamentos identificados con mayor frecuencia fueron los antidepresivos (11,2 %), analgésicos no esteroides (10,7 %). La ingesta fue la vía de exposición más común (93 %). El promedio de estadía de los pacientes en UCIP fue de 1,3 días. Dos pacientes ingresaron en la UCI: uno requirió intubación y otro hemodiálisis. Se determinaron relaciones estadísticamente significativas entre el sexo del paciente y la circunstancia de exposición, y entre la condición psiquiátrica del paciente y el número de sustancias tóxicas ingeridas. Conclusión. La mayoría de las intoxicaciones atendidas en la UCIP fueron intencionales y correspondieron a pacientes de sexo femenino, a quienes se les asoció alguna patología psiquiátrica. Los grupos de medicamentos identificados con mayor frecuencia fueron los antidepresivos y los antiinflamatorios no esteroides.

Introduction. Pediatric poisoning is a public health problem worldwide. The objective of this study was to establish the characteristics of pediatric cases of poisoning seen at the pediatric intensive care unit (PICU) of a hospital in Chile. Population and methods. The medical records of patients diagnosed with poisoning and admitted to the PICU between 2013 and 2017 were reviewed. Results. A total of 105 cases were identified, who account for 3% of all admissions recorded in the study period. Patients' median age was 10 years. In total, 73.3% of cases were female patients; 51% of cases were associated with intentional poisoning; and 83% were caused by drug exposure. The most common drugs identified were antidepressants (11.2%) and non-steroidal anti-inflammatory drugs (10.7%). Intake was the most frequent route of exposure (93%). The average length of stay in the PICU was 1.3 days. One patient required intubation and another required hemodialysis in the PICU. Statistically significant relationships were established between patient sex and the circumstance of exposure and between the patient's psychiatric condition and the number of toxic substances ingested. Conclusion. Most poisoning cases seen at the PICU were intentional and occurred in female patients, who had a psychiatric condition. The most common drugs identified were antidepressants and non-steroidal antiinflammatory drugs.

Avaliação do uso de psicofármacos por universitários / Evaluation of the use of psychopharmaceuticals by university students

Introdução: depressão e ansiedade têm sido observadas entre universitários, sendo apontado como desencadeadores a sobrecarga de tarefas, cobranças pessoais e familiares entre outros fatores que podem resultar na necessidade de uso de psicofármacos. Objetivo: avaliar o uso de psicofármacos por universitários. Metodologia: estudo transversal, utilizando questionário contendo informações sociodemográficas, econômicas e sobre uso de psicofármacos. Foi realizada análise bivariada com teste qui-quadrado de Pearson para verificar associação entre as variáveis utilização de antidepressivos/ansiolíticos e sociodemográficas e econômicas. Resultados: dos 408 entrevistados, 22,3% afirmaram fazer uso de ansiolíticos/antidepressivos, tendo iniciado após o ingresso na universidade e em uso diário. A maioria relata ter alterado a dosagem sem consultar o médico, asseguraram conhecimento sobre os efeitos adversos do medicamento, sabe que a remoção do medicamento deve ser feita de maneira gradual, mas afirmam ter interrompido o tratamento sem consultar o médico. Permaneceram associadas a utilização de psicofármacos, no modelo final, ser do sexo feminino (p=0,013), idade maior que 29 anos (p=0,009) e possuir plano de saúde (p=0,020). Conclusão: verificou-se a necessidade de alertar a comunidade acadêmica e gestão sobre a necessidade de acolhimento dos universitários em sofrimento mental e propor ações que visem orientar sobre o uso racional dos psicofármacos.

Introduction: depression and anxiety have been observed among university students, with task overload, personal and family demands being pointed out as triggers, among other factors that result in the use of psychotropic drugs. Objective: to evaluate the use of psychopharmaceuticals by university students. Methodology: cross-sectional study, using a questionnaire containing sociodemographic, economic and psychotropic drug use information. A bivariate analysis was performed with Pearson's chi-square test to verify the association between the variables use of antidepressants/anxiolytics and sociodemographic and economic variables. Results: of the 408 respondents, 22.3% said they used anxiolytics/antidepressants, having started after entering university and in daily use. The majority report having changed the dosage without consulting the doctor, assured knowledge about the adverse effects of the medication, know that the removal of the medication must be done gradually, but claim to have stopped the treatment without consulting the doctor. The use of psychotropic drugs in the final model, being female (p=0.013), older than 29 years (p=0.009) and having a health plan (p=0.020) remained associated. Conclusion: there was a need to alert the academic and management community about the need to welcome university students in mental distress and propose actions that aim to guide the rational use of psychotropic drugs.

Impacto del tratamiento de adultos mayores con ISRS y su relación con los tratamientos odontológicos / The impact of treating older adults with SSRI and its relationship with dental treatments

La población mayor de 60 años es el grupo etario de mayor crecimiento en el mundo. Debido a que la depresión es una patología frecuente en la persona adulta mayor y anciana, los inhibidores de la recap- tación de la serotonina (ISRS) son el tratamiento de primera línea de elección. Este trabajo referencia la asociación del consumo de estos fármacos con la disminución de la densidad ósea mineral (DMO), el riesgo de fracturas y su repercusión en la atención odontológica. Además, incluye una breve descripción de la homeostasis ósea y la relación depresión-carga alostática. El trabajo interdisciplinario y una correcta anamnesis pueden detectar posibles complicaciones y riesgos vinculados con este tipo de medicamen- tos. Ello facilitaría un mejor manejo, más aún en el adulto mayor, donde una pequeña variable puede repercutir en su integridad (AU)

The population over 60 is the fastest growing age group in the world. Depression is a frequent pathology in the elderly and the elderly, with serotonin reuptake inhibitors (SSRI) being the 1st line treatment of choice. The association of the consumption of this drug with a decrease in bone mineral density (BMD), risk of fractures and its impact on dental care are referenced in this work. In addition, it includes a brief description of bone homeostasis and the depression-allostatic load relationship. Interdisciplinary work and a correct anamnesis can detect possible complications and risks linked to this type of medication, facilitating better management and even more so in the elderly, where a small variable can affect their integrity (AU)

High efficiency of left superior frontal gyrus and the symptom features of major depressive disorder / 中南大学学报(医学版)

OBJECTIVES@#Major depressive disorder (MDD) patients with anhedonia tend to have a poor prognosis. The underlying imaging basis for anhedonia in MDD remains largely unknown. The relationship between nodal properties and anhedonia in MDD patients need to be further investigated. Herein, this study aims to explore differences of cerebral functional node characteristics in MDD patients with severe anhedonia (MDD-SA) and MDD patients with mild anhedonia (MDD-MA) before and after the antidepressant treatment.@*METHODS@#Ninety participants with current MDD were recruited in this study. 24-Item Hamilton Depression Scale (HAMD-24) and Snaith-Hamilton Pleasure Scale (SHAPS) were used to assess the severity of depression and anhedonia at baseline and the end of 6-months treatment. The MDD patients who scored above the 25th percentile on the SHAPS were assigned to an MDD-SA group (n=19), while those who scored below the 25th percentile were assigned to an MDD-MA group (n=18). All patients in the 2 groups received antidepressant treatment. Functional magnetic resonance imaging (fMRI) images of all the patients were collected at baseline and the end of 6-months treatment. Graph theory was applied to analyze the patients' cerebral functional nodal characteristics, which were measured by efficiency (ei) and degree (ki).@*RESULTS@#Repeated measures 2-factor ANCOVA showed significant main effects on group on the ei and ki values of left superior frontal gyrus (LSFG) (P=0.003 and P=0.008, respectively), and on the ei and ki values of left medial orbital-frontal gyrus (LMOFG) (P=0.004 and P=0.008, respectively). Compared with the MDD-MA group, the significantly higher ei and ki values of the LSFG (P=0.015 and P=0.021, respectively), and the significantly higher ei and ki values of the LMOFG (P=0.015 and P=0.037, respectively) were observed in the MDD-SA group at baseline. Meanwhile, higher SHAPS scores could result in higher ei and ki values of LSFG (P=0.019 and P=0.026, respectively), and higher ei value of LMOFG (P=0.040) at baseline; higher SHAPS scores could result in higher ei values of LSFG (P=0.049) at the end of 6-months treatment. The multiple linear regression analysis revealed that sex were negatively correlated with the ei and ki values of LSFG (r= -0.014, P=0.004; r=-1.153, P=0.001, respectively). The onset age of MDD was negatively correlated with the ki value of LSFG (r=-0.420, P=0.034) at the end of 6-months treatment. We also found that SHAPS scores at baseline were positively correlated with the HAMD-24 scores (r=0.387, P=0.022) at the end of 6-months treatment.@*CONCLUSIONS@#There are obvious differences in nodal properties between the MDD-SA and the MDD-MA patients, such as the high ei of LSFG in the MDD-SA patients, which may be associated with the severity of anhedonia. These nodal properties could be potential biomarkers for the prognosis of MDD. The increased ei and ki values in the LSFG of MDD-SA patients may underlie a compensatory mechanism or protective mechanism. The mechanism may be an important component of the pathological mechanism of MDD-SA. The poor prognosis in the MDD-SA patients suggests that anhedonia may predict a worse prognosis in MDD patients. Sex and onset age of MDD may affect the nodal properties of LSFG at baseline and the end of 6-months treatment.

A Network Pharmacology-Based Study on Antidepressant Effect of Salicornia europaea L. Extract with Experimental Support in Chronic Unpredictable Mild Stress Model Mice / 中国结合医学杂志

OBJECTIVE@#To investigate the pharmacodynamic material basis, mechanism of actions and targeted diseases of Salicornia europaea L. (SE) based on the network pharmacology method, and to verify the antidepressant-like effect of the SE extract by pharmacological experiments.@*METHODS@#Retrieval tools including Chinese medicine (CM), PubMed, PharmMapper, MAS 3.0 and Cytoscape were used to search the components of SE, predict its targets and related therapeutic diseases, and construct the "Component-Target-Pathway" network of SE for central nervous system (CNS) diseases. Further, protein-protein interaction (PPI) network, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) function annotation of depression-related targets were analyzed to predict the antidepressant mechanism of SE. Chronic unpredictable mild stress (CUMS) model was used to construct a mouse model with depression-like symptoms. And the animals were randomly divided into 6 groups (n=10) including the normal group (nonstressed mice administered with distilled water), the CUMS group (CUMS mice administered with distilled water), the venlafaxine group (CUMS mice administered with venlafaxine 9.38 mg/kg), SE high-, medium-, and low-dose groups (CUMS mice administered with SE 1.8, 1.35 and 0.9 g/kg, respectively). Then some relevant indicators were determined for experimental verification by the forced swim test (FST), the tail suspension test (TST) and open-field test (OFT). Dopamine (DA) concentration in hippocampus and cerebral cortex, IL-2 and corticosterone (CORT) levels in blood, and nuclear factor E2 related factor 2 (Nrf2), kelch-like epichlorohydrin related protein 1 (Keap1), NAD(P) H dehydrogenase [quinone] 1 (NQO1) and heme oxygenase-1 (HO-1) levels in mice were measured by enzyme linked immunosorbent assay (ELISA) and Western blot respectively to explore the possible mechanisms.@*RESULTS@#The "target-disease" network diagram predicted by network pharmacology, showed that the potential target of SE involves a variety of CNS diseases, among which depression accounts for the majority. The experimental results showed that SE (1.8, 1.35 g/kg) significantly decreased the immobility period, compared with the CUMS group in FST and TST in mice after 3-week treatment, while SE exhibited no significant effect on exploratory behavior in OFT in mice. Compared with CUMS group, the SE group (0.9 g/kg) showed significant differences (P<0.05) in DA levels in the hippocampus and cerebral cortex. In addition, compared with CUMS control group, SE (1.8 g/kg) group showed a significant effect on decreasing the activities of CORT (P<0.05), and serum IL-2 level with no statistical significance. Finally, Western blot results showed that compared with the model group, Nrf2, Keap1, NQO1 and HO-1 protein expressions in SE group (1.8 g/kg) were up-regulated (all P<0.01).@*CONCLUSION@#The SE extract may have an antidepressant effect, which appeared to regulate Nrf2-ARE pathway and increased levels of DA and CORT in the hippocampus and cortex.

Eficácia e segurança de Duloxetina comparado a outros antidepressivos disponíveis no SUS para o tratamento de depressão maior: revisão rápida de evidências / Effectiveness and safety of Duloxetine compared to other antidepressant agents available in Brazilian Public Health for treatment of major depression: rapid response review of evidence

Tecnologia: Duloxetina e outros antidepressivos disponíveis no Sistema Único de Saúde (amitriptilina, nortriptilina, clomipramina, fluoxetina e bupropiona). Indicação: Tratamento do primeiro episódio depressivo no transtorno de depressão maior em adultos. Pergunta: A duloxetina é mais eficaz e tolerável que a amitriptilina, nortriptilina, clomipramina, fluoxetina e bupropiona para o tratamento do primeiro episódio de depressão maior em adultos? Métodos: Revisão rápida de evidências (overview) de revisões sistemáticas, com levantamento bibliográfico realizado na base de dados PUBMED, utilizando estratégia estruturada de busca. A qualidade metodológica das revisões sistemáticas foi avaliada com AMSTAR-2 (Assessing the Methodological Quality of Systematic Reviews). Resultados: Foi selecionada 1 revisão sistemática, que atendia aos critérios de inclusão. Conclusão: Os antidepressivos, comparados ao placebo, tinham maior taxa de resposta, taxa de remissão e taxa de descontinuação devido a efeitos colaterais, no tratamento de curto prazo. Duloxetina tinha taxa de resposta similar a amitriptilina, clomipramina, fluoxetina e bupropiona. Duloxetina e amitriptilina tinham maior taxa de remissão que fluoxetina. Comparando-se as taxas de abandono de tratamento devido a efeitos colaterais, clomipramina era menos seguro, amitriptilina, bupropiona e duloxetina eram parecidos entre si, e fluoxetina era o antidepressivo mais seguro

Technology: Duloxetine and other antidepressants available in the Brazilian Public Health System (amitriptyline, nortriptyline, clomipramine, fluoxetine and bupropion). Indication: Treatment of the first depressive episode in adult major depressive disorder. Question: Is duloxetine more effective and tolerable than amitriptyline, nortriptyline, clomipramine, fluoxetine and bupropion for the treatment of first episode of major depression in adults? Methods: Rapid response review of evidence (overview) from systematic reviews, with a bibliographic search in the PUBMED database, using a structured strategy. The methodological quality of systematic reviews was assessed with AMSTAR-2 (Methodological Quality Assessment of Systematic Reviews). Results: One systematic review was selected, which met the inclusion criteria. Conclusion: In short-term treatment, antidepressants, compared to placebo, had a higher rate of response, rate of remission and rate drop-out due to side effects. Duloxetine had a similar response rate to amitriptyline, clomipramine, fluoxetine and bupropion. Duloxetine and amitriptyline had higher remission rates than fluoxetine. Comparing rates of dropout due to side effects, clomipramine had the worst rates, amitriptyline, bupropion, and duloxetine were similar to each other, and fluoxetine had the better rates
