Esketamine, the S (+) enantiomer of ketamine, is the most widely used form in the anesthetic environment in some countries, and new studies have shown that it may also be effective in depression and with better tolerability. However, no study so far has directly compared esketamine with racemic ketamine. Here we propose a protocol of a clinical trial to evaluate esketamine as a noninferior medicationMethods/design: This study protocol is for a randomized, controlled, double-blind noninferiority clinical trial. Subjects will be 18 years or older, with major depression characterized as treatment-resistant. Participants will receive a single infusion of either esketamine (0.25mg/kg) or ketamine (0.5 mg/kg) over 40 minutes. The primary outcome will be the difference in remission rates between the 2 treatment arms at 24 and 72hours after drug infusion. Secondary outcomes will include other timepoints, measurements of cognition, dissociation, and blood biomarkers. Discussion: A head-to-head study is the best way to evaluate whether the esketamine is in fact comparable to the racemic ketamine in terms of both efficacy and safety, and, if positive, it would be an initial step to increase the access to that type of treatment worldwide. Ethics and dissemination: The study was approved by the local Institutional Review Board (University Hospital Professor Edgard Santos—Federal University of Bahia—Number: 46657415.0.0000.0049). Subjects will only participate after voluntarily agreeing and signing the Informed Consent Form. The study findings will be published in peer-reviewed journals and presented at national and international conferences. Trial registration: This trial has been registered in the Japan Primary Registries Network (JPRN): UMIN000032355, which is affiliated with the World Health Organization. when compared to ketamine in the treatment of patients with treatment-resistant depression

Relações entre profissionais de saúde e usuários durante as práticas em saúde Relationships between health professionals and users throughout health care practices

Apresenta-se uma revisão integrativa sobre estudos que abordam as relações entre profissionais de saúde e usuários durante as práticas em saúde. Objetivou-se identificar os aspectos pesquisados no cotidiano dos serviços acerca dessas relações. A coleta foi realizada nas bases Lilacs e Pubmed segundo os descritores: acolhimento; relações profissional-família; relações profissional-paciente; humanização da assistência; e a palavra 'vínculo' associada ao descritor Sistema Único de Saúde. Selecionaram-se 290 estudos publicados entre 1990 e 2010. Por meio da análise temática, foram criados cinco núcleos de sentido: a relevância da confiança na relação profissional-usuário; sentimentos e sentidos na prática do cuidado; a importância da comunicação nos serviços de saúde; modo de organização das práticas em saúde; e (des)colonialismo. Identificou-se que as relações estabelecidas nas práticas de saúde têm uma dimensão transformadora. No entanto, permanece o desafio de humanizar os serviços de saúde. A enfermagem se destaca na produção do conhecimento nessa temática.<br>This article presents an integrative review about studies that address the relationships between health professionals and users in health care practices. It aimed to identify aspects that were researched on the daily life of the services concerning such relationships. Data were collected from the Lilacs and Pubmed databases based on these descriptors: user embracement; professionalfamily relations; professionalpatient relations; humanization of the care; and the bonding word associated to the Single Health System descriptor. Two hundred and ninety studies, published from 1990 to 2010, were selected. Through thematic analyses, five meaning cores were created: the relevance of the confidence in the professionaluser relationship; feelings and senses in the health care practice; the importance of communications in health care services; ways to organize health care practices and (de)colonialism. It was found that relationships established in health care practices have a transformative dimension. However, the challenge to humanize health care services remains. Nursing stands out in the production of knowledge on such theme

AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forest

The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer-reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non-invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from different Amazon regions to compile the most extensive data set of inventories of mammal, bird, and reptile species ever assembled for the area. The complete data set comprises 154,123 records of 317 species (185 birds, 119 mammals, and 13 reptiles) gathered from surveys from the Amazonian portion of eight countries (Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela). The most frequently recorded species per taxa were: mammals: Cuniculus paca (11,907 records); birds: Pauxi tuberosa (3713 records); and reptiles: Tupinambis teguixin (716 records). The information detailed in this data paper opens up opportunities for new ecological studies at different spatial and temporal scales, allowing for a more accurate evaluation of the effects of habitat loss, fragmentation, climate change, and other human-mediated defaunation processes in one of the most important and threatened tropical environments in the world. The data set is not copyright restricted; please cite this data paper when using its data in publications and we also request that researchers and educators inform us of how they are using these data
