ABSTRACT
RESUMO O objetivo deste estudo foi analisar a literatura científica no período de janeiro de 2006 a março de 2021 sobre as repercussões da perda gestacional na conjugalidade e na parentalidade. Trata-se de uma revisão sistemática que envolveu consulta às bases Pubmed, PsycNET e Portal BVS, por meio de descritores estabelecidos previamente, resultando em 16 estudos elegíveis para análise. Foram encontrados resultados contrastantes quanto às repercussões da perda gestacional na parentalidade, sugerindo a necessidade de investigação de fatores de proteção. A perda apresentou-se como risco à conjugalidade, porém a comunicação conjugal emergiu como fator de proteção que merece maior investigação. Estudos futuros devem adotar métodos qualitativos ou mistos, incluir a perspectiva masculina sobre o tema e avaliar intervenções conjugais e familiares.
ABSTRACT This study aimed to analyze the scientific production from Jan 2006 to Mar 2021 regarding the repercussions of pregnancy loss on conjugality and parenthood. It is a systematic review carried out in Pubmed, PsycNET, and Portal BVS database through previously established descriptors, resulting in 16 eligible studies. We found contrasting results regarding repercussions in parenthood, suggesting the need to investigate protective factors also. Pregnancy loss shows as a risk for marital relationships, but marital communication emerged as a possible protection factor that deserves further investigation. Future research should adopt qualitative and mixed methods, include mens perspectives, and evaluate marital and family interventions.
RESUMEN El objetivo de este estudio ha sido analizar la literatura científica en el período de enero de 2006 hasta marco de 2021 sobre las repercusiones de la pérdida gestacional en la conyugalidad y en la parentalidad. Esta es una revisión sistemática realizada en las bases Pubmed, PsycNET y Portal BVS, con los descriptores establecidos previamente, resultando en 16 estudios elegibles. Se encontraron resultados contrastantes en cuanto a las repercusiones en la crianza de los hijos, sugiriendo la necesidad de investigar también los factores protectores. La pérdida se presentó como un riesgo para la conyugalidad, sin embargo, la comunicación marital emergió como un posible factor protector que merece más estudios. Se indica que futuras investigaciones adopten métodos cualitativos, que incluyan la perspectiva masculina y evalúen intervenciones conyugales y familiares.

The study presented in this paper aimed at understanding how anorexic young women use virtual environments as spaces of sociability in order to construct a narrative about anorexia, anchor their experiences through emotional mutuality and validate discourses. To do so, an analysis of the content found in the commenting and posting sections of pro-anorexia blogs was carried out. Three thematic categories were identified: body, personal identity and sociability on the web. It was observed that blogs are virtual spaces of sociability and construction of identity groups. The representations and the experiences lived by the corporal materiality feed cyberspace and are the starting point for understanding a phenomenon particular to the contemporaneity, that is the virtual exchanges. In blogs, one can find body narratives that seek to give coherence to an individual and to his or her existence as well as narratives that aim at anchoring and legitimizing personal experiences and validating pro-anorexia attitudes. Social ties are strengthened within the group, which becomes an emotional community. The meanings of the spreading discourses allow us to infer that in these groups, the materiality of anorexic bodies emancipates itself from the social stigmas of a disease.
O presente artigo procurou compreender como jovens anoréxicas utilizam ambientes virtuais como espaços de sociabilidade para a construção de uma narrativa sobre a anorexia, para ancorar suas experiências pela mutualidade emocional e para validar discursos. Realizou-se análise de conteúdo da sessão de comentários e posts de blogs pró-anorexia sendo identificadas três categorias temáticas: corpo, identidade pessoal e sociabilidade na rede. Observou-se que os blogs são espaços virtuais de sociabilidade e de construção de coletivos identitários. As representações e as vivências pela materialidade corporal alimentam o cyber espaço e são o ponto de partida para compreensão de um fenômeno particular à contemporaneidade, que são as trocas virtuais. Nos blogs localizam-se narrativas corporais que procuram dar coerência ao indivíduo e à sua existência bem como ancorar e legitimar experiências pessoais e validar atitudes pró-anorexia. São reforçados os laços sociais dentro do grupo que se transforma em uma comunidade emocional. Os sentidos dos discursos circulantes permitem inferir que nestes grupos, a materialidade dos corpos anoréxicos se emancipa dos estigmas sociais de doença.

Serotonergic psychedelics are emerging as potential antidepressant therapeutic tools, as suggested in a recent randomized controlled trial with ayahuasca for treatment-resistant depression. Preclinical and clinical studies have suggested that serum brain-derived neurotrophic factor (BDNF) levels increase after treatment with serotoninergic antidepressants, but the exact role of BDNF as a biomarker for diagnostic and treatment of major depression is still poorly understood. Here we investigated serum BDNF levels in healthy controls (N = 45) and patients with treatment-resistant depression (N = 28) before (baseline) and 48 h after (D2) a single dose of ayahuasca or placebo. In our sample, baseline serum BDNF levels did not predict major depression and the clinical characteristics of the patients did not predict their BDNF levels. However, at baseline, serum cortisol was a predictor of serum BDNF levels, where lower levels of serum BDNF were detected in a subgroup of subjects with hypocortisolemia. Moreover, at baseline we found a negative correlation between BDNF and serum cortisol in volunteers with eucortisolemia. After treatment (D2) we observed higher BDNF levels in both patients and controls that ingested ayahuasca (N = 35) when compared to placebo (N = 34). Furthermore, at D2 just patients treated with ayahuasca (N = 14), and not with placebo (N = 14), presented a significant negative correlation between serum BDNF levels and depressive symptoms. This is the first double-blind randomized placebo-controlled clinical trial that explored the modulation of BDNF in response to a psychedelic in patients with depression. The results suggest a potential link between the observed antidepressant effects of ayahuasca and changes in serum BDNF, which contributes to the emerging view of using psychedelics as an antidepressant. This trial is registered at http://clinicaltrials.gov (NCT02914769).
ABSTRACT
Major depression is a psychiatric disorder with high prevalence in the general population, with increasing expression in adolescence, about 14% in young people. Frequently, it presents as a chronic condition, showing no remission even after several pharmacological treatments and persisting in adult life. Therefore, distinct protocols and animal models have been developed to increase the understanding of this disease or search for new therapies. To this end, this study investigated the effects of chronic social isolation and the potential antidepressant action of nortriptyline in juvenile Callithrix jacchus males and females by monitoring fecal cortisol, body weight, and behavioral parameters and searching for biomarkers and a protocol for inducing depression. The purpose was to validate this species and protocol as a translational model of juvenile depression, addressing all domain criteria of validation: etiologic, face, functional, predictive, inter-relational, evolutionary, and population. In both sexes and both protocols (IDS and DPT), we observed a significant reduction in cortisol levels in the last phase of social isolation, concomitant with increases in autogrooming, stereotyped and anxiety behaviors, and the presence of anhedonia. The alterations induced by chronic social isolation are characteristic of the depressive state in non-human primates and/or in humans, and were reversed in large part by treatment with an antidepressant drug (nortriptyline). Therefore, these results indicate C. jacchus as a potential translational model of juvenile depression by addressing all criteria of validation.
