Disability related to chronic low back pain: prevalence abd associated factors

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Disability related to chronic low back pain (CLBP) is a complex and multidimensional phenomenon. The aim of the study was to identify the prevalence of disability and factors associated with disability outcome in 177 CLBP adults. Respondents were recruited from three health care service centers and answered questions from: Demographic Identification Form, Oswestry Disability Index, Chronic Pain Self-efficacy Scale, Tampa Scale Kinesiophobia, Beck Depression Inventory, and the Revised Piper Fatigue Scale. The prevalence of disability among the respondents was 65% (95% CI: 57.5 - 72.0), and disability was moderate to severe in 80.7% of them. The multiple regression model identified three factors as independently associated with disability: work situation, low self-efficacy and depression. The factors identified to be associated with disability are modifiable. Interventions such as work relocation, depression treatment and re-conceptualization of self-efficacy may have an important impact in preventing and reducing disability in chronic low back pain patients.46SI1623Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Using gene expression profiles from peripheral blood to identify asymptomatic responses to acute respiratory viral infections

<p>Abstract</p> <p>Background</p> <p>A recent study reported that gene expression profiles from peripheral blood samples of healthy subjects prior to viral inoculation were indistinguishable from profiles of subjects who received viral challenge but remained asymptomatic and uninfected. If true, this implies that the host immune response does not have a molecular signature. Given the high sensitivity of microarray technology, we were intrigued by this result and hypothesize that it was an artifact of data analysis.</p> <p>Findings</p> <p>Using acute respiratory viral challenge microarray data, we developed a molecular signature that for the first time allowed for an accurate differentiation between uninfected subjects prior to viral inoculation and subjects who remained asymptomatic after the viral challenge.</p> <p>Conclusions</p> <p>Our findings suggest that molecular signatures can be used to characterize immune responses to viruses and may improve our understanding of susceptibility to viral infection with possible implications for vaccine development.</p

Focused Deterrence and the Prevention of Violent Gun Injuries: Practice, Theoretical Principles, and Scientific Evidence

Focused deterrence strategies are a relatively new addition to a growing portfolio of evidence-based violent gun injury prevention practices available to policy makers and practitioners. These strategies seek to change offender behavior by understanding the underlying violence-producing dynamics and conditions that sustain recurring violent gun injury problems and by implementing a blended strategy of law enforcement, community mobilization, and social service actions. Consistent with documented public health practice, the focused deterrence approach identifies underlying risk factors and causes of recurring violent gun injury problems, develops tailored responses to these underlying conditions, and measures the impact of implemented interventions. This article reviews the practice, theoretical principles, and evaluation evidence on focused deterrence strategies. Although more rigorous randomized studies are needed, the available empirical evidence suggests that these strategies generate noteworthy gun violence reduction impacts and should be part of a broader portfolio of violence prevention strategies available to policy makers and practitioners

Anacardium plants: Chemical,nutritional composition and biotechnological applications

Anacardium plants are native to the American tropical regions, and Anacardium occidentale L. (cashew tree) is the most recognized species of the genus. These species contain rich secondary metabolites in their leaf and shoot powder, fruits and other parts that have shown diverse applications. This review describes the habitat and cultivation of Anacardium species, phytochemical and nutritional composition, and their industrial food applications. Besides, we also discuss the secondary metabolites present in Anacardium plants which display great antioxidant and antimicrobial effects. These make the use of Anacardium species in the food industry an interesting approach to the development of green foods.AK.

A comunicação da suspensão de cirurgias pediátricas: sentimentos dos familiares envolvidos no processo

A hospitalização é uma experiência complexa, sendo agravada no caso de necessidade de intervenção cirúrgica, principalmente quando o paciente é criança. Quando a cirurgia é suspensa, paciente e seus familiares podem apresentar sentimentos de insegurança, angústia e ansiedade. Este estudo teve como objetivo identificar e descrever a percepção de quinze mães e/ou responsáveis por crianças de 0 a 18 anos, internadas em um hospital, após receberem a notícia de que a cirurgia de seu filho foi suspensa. É um estudo descritivo, qualitativo, que utilizou o referencial teórico da Comunicação Interpessoal e o metodológico da Análise de Conteúdo. Os resultados evidenciaram que as suspensões de cirurgias pediátricas são fatos presentes na instituição, que trazem repercussões ao paciente e familiares, e à organização institucional; que a comunicação entre profissionais da saúde, pacientes e familiares é inadequada; que a atuação do enfermeiro na notícia da suspensão da cirurgia precisa ser efetiva.La hospitalización es una experiencia compleja, agravada en el caso de ser necesaria una intervención quirúrgica, en particular cuando el enfermo es un niño.

Los resultados evidenciaron que las suspensiones de cirugías pediátricas son hechos presentes en la institución, que traen repercusiones al enfermo y familiares y en la propia organización institucional, que la comunicación entre profesionales de la salud, enfermos y familiares es inadecuada y que la actuación del enfermero en la noticia de la suspensión de la cirugía debe ser necesariamente efectiva.Hospitalization is a complex experience; this can be made worse if surgical intervention is required, especially when the patient is a child. When surgery is suspended, patient and family can experience feelings of insecurity, distress, and anxiety. The objective of this study was to identify and describe the perceptions of fifteen mothers or guardians of children between 0 and 18 years old admitted in a teaching hospital, after receiving news that surgery for their child was suspended. This was a descriptive qualitative study which used Interpersonal Communication as theoretical reference and Analysis of Content as the methodology. Results showed that suspension of pediatric surgery in our institution causes repercussions to patients, their families, and institution organisation; that communication between health team professionals, patients and families is inadequate; and that the nurses' participation in informing surgery suspension must be effective

Expanding the Understanding of Biases in Development of Clinical-Grade Molecular Signatures: A Case Study in Acute Respiratory Viral Infections

The promise of modern personalized medicine is to use molecular and clinical information to better diagnose, manage, and treat disease, on an individual patient basis. These functions are predominantly enabled by molecular signatures, which are computational models for predicting phenotypes and other responses of interest from high-throughput assay data. Data-analytics is a central component of molecular signature development and can jeopardize the entire process if conducted incorrectly. While exploratory data analysis may tolerate suboptimal protocols, clinical-grade molecular signatures are subject to vastly stricter requirements. Closing the gap between standards for exploratory versus clinically successful molecular signatures entails a thorough understanding of possible biases in the data analysis phase and developing strategies to avoid them.Using a recently introduced data-analytic protocol as a case study, we provide an in-depth examination of the poorly studied biases of the data-analytic protocols related to signature multiplicity, biomarker redundancy, data preprocessing, and validation of signature reproducibility. The methodology and results presented in this work are aimed at expanding the understanding of these data-analytic biases that affect development of clinically robust molecular signatures.Several recommendations follow from the current study. First, all molecular signatures of a phenotype should be extracted to the extent possible, in order to provide comprehensive and accurate grounds for understanding disease pathogenesis. Second, redundant genes should generally be removed from final signatures to facilitate reproducibility and decrease manufacturing costs. Third, data preprocessing procedures should be designed so as not to bias biomarker selection. Finally, molecular signatures developed and applied on different phenotypes and populations of patients should be treated with great caution
