Isolation and Comparative Genomic Analysis of Final Third of Satis Genome
A highly novel Streptomyces phage, Satis, was isolated from a direct environmental sample collected from outside Danforth House on the Washington University campus. Satis infects bacterial species Streptomyces lividans producing pinpoint, cloudy plaques less than 1mm in diameter. Electron microscope data shows rare atypical physical features. Rather than the common octahedral capsid shape, Satis has a prolate head with visible cross-linked hexagonal protein structure and average measurements of 285 nm by 47 nm with a long, flexible tail measuring 268 nm. Upon sequencing, it was found that Satis contains the longest phage genome discovered to date through the SEA-PHAGE program at 186,702 base pairs. The genome is quite novel in sequence, as its closest genetic match, bacteriophage Chymera, is similar across only 15.9% of the genome. This means that Satis belongs to no known previously characterized cluster and is considered a Singleton phage. The genome contains 325 protein coding genes, of which our group analyzed Gene 230 to the end of the genome. The vast majority of the genes in this section run 3’ to 5’ and compared to the other two sections, these genes seem to be the most unique in primary, secondary, and tertiary structure. Due to the novelty of Satis, functional evidence from comparative genomic analysis is sparse. We are currently in the process of a more thurough comparative genomic analysis between Satis and other Streptomyces phages, particularly phage JustBecause, another Streptomyces phage isolated by Washington University in St. Louis students in 2016 with similar morphology to Satis
Adverse childhood experiences and suicide attempts in morbidly obese adults
Introdução: As tentativas de suicÃdio surgem frequentemente associadas a problemas alimentares, tanto anorexia quanto bulimia. Do mesmo modo, tem-se verifi cado uma elevada ocorrência de suicÃdio entre obesos. Investigações têm mostrado que a adversidade na infância pode ser um fator de
risco para as tentativas de suicÃdio.
Objetivos: Caracterizar e compreender a relação entre experiências de adversidade na infância e tentativas de suicÃdio em 100 obesos mórbidos
candidatos a cirurgia bariátrica.
Métodos: Um total de 100 pacientes foram selecionados de setembro de 2007 a outubro de 2007 e de janeiro de 2008 a janeiro de 2009, sendo que 20 pacientes eram do sexo feminino. A média de idade era de 38,89±9,87 anos, e a média do peso máximo era de 136,43±14 kg. O Questionário da
História de Adversidade na Infância foi utilizado para avaliar experiências adversas.
Resultados: 88% dos pacientes relataram a existência de pelo menos uma experiência de adversidade na infância, e 25% relataram já ter realizado pelo menos
uma tentativa de suicÃdio. A adversidade na infância esteve associada a um risco aumentado para realizar tentativas de suicÃdio (odds ratio = 2,026).
Conclusão: Esses dados devem ser levados em consideração na avaliação e no acompanhamento desses pacientes.Introduction: Suicide attempts are often associated with eating disorders, both anorexia and bulimia. Likewise, a high incidence of suicide has been
observed among obese patients. Previous studies have shown that adverse experiences in childhood may be a risk factor for suicide attempts.
Objectives: To characterize and to understand the relationship between adverse experiences and suicide attempts in 100 morbidly obese patients
referred for bariatric surgery.
Methods: A total of 100 patients were selected from September 2007 to October 2007 and from January 2008 to January 2009. Of these, 20 patients
were females. Mean age was 38.89±9.87 years, and mean maximum weight was 136.43±14 kg. The Portuguese version of the Family ACE (Adverse
Childhood Experiences) Questionnaire was used to assess the occurrence of adverse events.
Results: 88% of the patients reported the existence of at least one adverse experience in childhood, and 25% reported at least one previous suicide
attempt. Adversity in childhood was associated with an increased risk for suicide attempts (odds ratio = 2.026).
Conclusion: These data should be taken into account in the assessment and monitoring of these patients.Fundação para a Ciência e a Tecnologia (FCT); (SFRH/BD/37069/2007)
An exploratory mixed methods study of the acceptability and effectiveness of mindfulness -based cognitive therapy for patients with active depression and anxiety in primary care
BACKGROUND: Mindfulness Based Cognitive Therapy (MBCT) is an 8-week course developed for patients with relapsing depression that integrates mindfulness meditation practices and cognitive theory. Previous studies have demonstrated that non-depressed participants with a history of relapsing depression are protected from relapse by participating in the course. This exploratory study examined the acceptability and effectiveness of MBCT for patients in primary care with active symptoms of depression and anxiety METHODS: 13 patients with recurrent depression or recurrent depression and anxiety were recruited to take part in the study. Semi-structured qualitative interviews were conducted three months after completing the MBCT programme. A framework approach was used to analyse the data. Beck depression inventories (BDI-II) and Beck anxiety inventories (BAI) provided quantitative data and were administered before and three months after the intervention. RESULTS: The qualitative data indicated that mindfulness training was both acceptable and beneficial to the majority of patients. For many of the participants, being in a group was an important normalising and validating experience. However most of the group believed the course was too short and thought that some form of follow up was essential. More than half the patients continued to apply mindfulness techniques three months after the course had ended. A minority of patients continued to experience significant levels of psychological distress, particularly anxiety. Statistically significant reductions in mean depression and anxiety scores were observed; the mean pre-course depression score was 35.7 and post-course score was 17.8 (p = 0.001). A similar reduction was noted for anxiety with a mean pre-course anxiety score of 32.0 and mean post course score of 20.5 (p = 0.039). Overall 8/11 (72%) patients showed improvements in BDI and 7/11 (63%) patients showed improvements in BAI. In general the results of the qualitative analysis agreed well with the quantitative changes in depression and anxiety reported. CONCLUSION: The results of this exploratory mixed methods study suggest that mindfulness based cognitive therapy may have a role to play in treating active depression and anxiety in primary care
Psychological treatment of depression: A meta-analytic database of randomized studies
Abstract Background A large number of randomized controlled studies have clearly demonstrated that psychological interventions are effective in the treatment of depression. The number of studies in this area is increasing rapidly. In this paper, we present a database of controlled and comparative outcome studies on psychological treatments of depression, based on a series of meta-analyses published by our group. The database can be accessed freely through the Internet. Description We conducted a comprehensive literature search of the major bibliographical databases (Pubmed; Psycinfo; Embase; Cochrane Central Register of Controlled Trials) and we examined the references of 22 earlier meta-analyses of psychological treatment of depression. We included randomized studies in which the effects of a psychological therapy on adults with depression were compared to a control condition, another psychological intervention, or a combined treatment (psychological plus pharmacological). We conducted nine meta-analyses of subgroups of studies taken from this dataset. The 149 studies included in these 9 meta-analyses are included in the current database. In the 149 included studies, a total of 11,369 patients participated. In the database, we present selected characteristics of each study, including characteristics of the patients (the study population, recruitment method, definition of depression); characteristics of the experimental conditions and interventions (the experimental conditions, N per condition, format, number of sessions); and study characteristics (measurement times, measures used, attrition, type of analysis and country). Conclusion The data on the 149 included studies are presented in order to give other researchers access to the studies we collected, and to give background information about the meta-analyses we have published using this dataset. The number of studies examining the effects of psychological treatments of depression has increased considerably in the past decades, and this will continue in the future. The database we have presented in this paper can help to integrate the results of these studies in future meta-analyses and systematic reviews on psychological treatments for depression
Description of arts therapies practice with adults suffering from depression in the UK: quantitative results from the nationwide survey
There is growing evidence that arts therapies may be under-used treatments for the 'global burden' of depression. However, the experiences of arts therapists, their methods, tools and ways of working with this client group remain unclear. Arts therapies in the UK are a form of psychotherapy. They use arts media alongside therapeutic relationship as means of therapeutic change and include four disciplines: Art Therapy (AT), Music Therapy (MT), Dance Movement Psychotherapy (DMP) and Drama Therapy (DT). In 2011, all arts therapists registered in the UK were invited to complete an online questionnaire concerning their practice in general and specifically in relation to clients with depression. The Arts Therapies Survey received 395 responses. Arts therapists who work primarily with depression were identified and compared to those who do not work with depression on a range of factors, including preferred theoretical approaches and style of working. Arts therapists who specialise in depression tend to follow Psychodynamic principles more often, are more likely to be older and experienced, work with groups, in health settings and with adults more often than children or adolescents. These quantitative findings enable the description of most common practice of arts therapies with depression in the UK and are intended to serve as a reference for arts therapists themselves and other professionals interested in the treatment of depression. Qualitative data gathered in the survey will be presented in a separate paper, with the aim of deepening the understanding already gained. © 2013 Elsevier Ltd
Characteristics of suicide attempters with family history of suicide attempt: a retrospective chart review
<p>Abstract</p> <p>Background</p> <p>Family history of suicide attempt is one of the risks of suicide. We aimed at exploring the characteristics of Japanese suicide attempters with and without a family history of suicide attempt.</p> <p>Methods</p> <p>Suicide attempters admitted to an urban emergency department from 2003 to 2008 were interviewed by two attending psychiatrists on items concerning family history of suicide attempt and other sociodemographic and clinical information. Subjects were divided into two groups based on the presence or absence of a family history of suicide attempt, and differences between the two groups were subsequently analyzed.</p> <p>Results</p> <p>Out of the 469 suicide attempters, 70 (14.9%) had a family history of suicide attempt. A significantly higher rate of suicide motive connected with family relations (odds ratio 2.21, confidence interval 1.18–4.17, <it>p </it>< .05) as well as a significantly higher rate of deliberate self-harm (odds ratio 2.51, confidence interval 1.38–4.57, <it>p </it>< .05) were observed in patients with a family history of suicide compared to those without such history. No significant differences were observed in other items investigated.</p> <p>Conclusion</p> <p>The present study has revealed the characteristics of suicide attempters with a family history of suicide attempt. Further understanding of the situation of such individuals is expected to lead to better treatment provision and outcomes, and family function might be a suitable focus in their treatment.</p
