The Immunomodulatory Role of Alcohol on HIV-Infected Monocyte-Derived Dendritic Cells

Alcohol is known to induce inflammation in the presence of the human immunodeficiency virus (HIV). In our previous studies, we revealed that alcohol induces cannabinoid receptors which play a role in the regulation of inflammatory cytokine production in monocyte-derived dendritic cells (MDDC). However, the ability of alcohol to alter MDDC function during HIV infection has not been clearly elucidated yet. To study the potential impact of alcohol on HIV-infected MDDC (confirmed by p24 ELISA), monocytes were isolated from commercially available buffy coats and cultured for 7 days with GM-CSF and IL-4. MDDC were infected with HIV- 1Ba-L and treated with different concentrations of alcohol (0.1% band 0.2%) for 4-7 days. MDDC phenotype, endocytosis, cytokine production, and ability to transmit HIV to T cells were analyzed. Uninfected CD4+ T cells were co-cultured for 7 days with either infected/treated MDDC or the supernatants from infected/treated MDDC. Inflammatory cytokine arrays were performed using supernatants from HIV-infected MDDC treated with alcohol. Results showed that HIV positive MDDC treated with alcohol had higher levels of infection compared to untreated HIV positive controls. CD4+ T cells exposed to HIV-infected MDDC acquired 100-fold higher levels of p24 compared to CD4+ T cells exposed to only supernatants. CD4+ T cells exposed to HIV-infected and alcohol-treated MDDC had higher levels of infection compared to controls. Cytokine array data show dysregulation of cytokine production by alcohol. In addition, MDDC phenotype and endocytic capacity were altered in the alcohol treated MDDC. Our results indicate a crucial role of MDDC in HIV transmission to T cells and provide insights into the inflammatory role alcohol exerts on dendritic cell function in the context of HIV infection.

Validação do conteúdo do diagnóstico de enfermagem proteção ineficaz para pacientes submetidos à hemodiálise

Methodological study, in order to validate the content of the nursing diagnosis protection ineffective in patients undergoing hemodialysis. The research took place in two stages, namely: concept analysis and content analysis of the instrument by experts. T he first step was operationalized through an integrative review of the databaes LILACS, CINAHL, PubMed, Scopus and Cochrane, with the key words protection and hemodialysis, in October and November 2013. The sample consisted of 32 articles, which were analyz ed by a c areful reading to identify the sections that correspond ed to the defining attributes , antecedents and consequences of protection in patients undergoing hemodialysis. T he interpretation for the diagnosis of effective protection was made by transpos ing the components of the diagnosis (definition, defining characteristics and related factors) to the denial form . In the second stage, we elaborated an instrument with the components of the nursing diagnostic s studied and proceeded to the analysis conduct ed in April 2014 by 22 specialists in nephrology and in the terminology of the NANDA International, selected by means of th e Lattes Platform . We used the binomial test to assess the proportion of experts who rated each item as appropriate, considering a si gnificance level of 5%. The project was approved by the Ethics Committee of the institution responsible for the research, an opinion on num b er 387 837 and CAAE 18486413.0.0000.5537. The results show that the proposal for the nursing diagnosis of ineffectiv e protection in patients undergoing hemodialysis is: definition - the same as that presented in the NANDA International Taxonomy II, location - domain safety / protection and class injury. Related factors are: Absence of routine vaccines; Non - adherence to care related to vascular access; Non - adherence to infection control measures; Non - adherence to prescribed diet; Non - adherence to drug therapy; Presence of comorbidities; Drug abuse; Immune disorders; Extremes of age; Abnormal blood profiles; Drugs that red uce immunity; and side effects and adverse treatment - related. The defining characteristics are: Presence of invading the bloodstream; Nutritional disorders; Increase in the number of hospitalizations; Uncontrolled dry weight; Infected vascular access; Vasc ular inadequate access; Increased blood pressure; fever; Bleeding disorder; Disability immunity; fatigue; weakness; itching; and maladaptive response to stress. It follows that the identification of the defining attributes, antecedents and consequences inc reased the wealth of vocabulary, allowing the construction of theoretical and empirical definitions for a broader understanding of the concept protection. Furthermore, the study contributed to the enrichment of nursing specific body of knowledge, as well a s in the direction of nursing care for patients undergoing hemodialysis.

Sentimentos de Paranóia e de Vergonha nos Sem-Abrigo

A população “sem-abrigo” e todos os problemas envolventes, como a pobreza e a exclusão social apresentam uma complexidade cada vez mais inquietante e preocupante na nossa sociedade. O fenómeno multifacetado dos sem-abrigo constitui um grave problema social. A pertinência deste estudo prende-se com a escassez de investigação relativa à população sem-abrigo e perceber melhor a sua complexidade, nomeadamente no que respeita à caracterização psicológica dos indivíduos sem-abrigo. Neste sentido, o presente estudo tem como objectivo conhecer melhor esta população através da recolha de informação relativa aos seus receios, valores, prazeres, percepção do motivo da sua situação, consumo de substâncias psicotrópicas, contacto com a família e amigos. Paralelamente pretendemos avaliar os sentimentos de vergonha (em função de experiências negativas precoces), de paranóia e emoções negativas (depressão, ansiedade e stress) nesta população específica e analisar a relação entre estas variáveis. A amostra é constituída por 56 sujeitos na condição de sem-abrigo, com uma média de idade de 40,86 e de 7 anos de escolaridade, sendo a maioria (n=49) do sexo masculino. O protocolo de avaliação, para além do questionário psicossocial desenvolvido para o efeito, incluía ainda escalas para medir a Depressão, Ansiedade e Stress (DASS-21), Vergonha Externa (OAS), Vergonha Interna (ISS) e Paranóia (GPS). Os dados do nosso estudo permitiram pôr em evidência algumas das dificuldades mais significativas dos sem-abrigo, nomeadamente, as rupturas dos laços familiares, o desemprego e a toxicodependência entre outros. Constatámos que os sem-abrigo da nossa amostra apresentam valores médios mais elevados de paranóia, vergonha externa e interna, quando comparados com os valores da população normal. Verifica-se ainda que quando mais escolarizada é a nossa amostra, menor sintomatologia depressiva e relacionada com o stress apresenta. Encontrámos correlações significativas positivas e moderadas entre as variáveis em estudo. Dada a escassez de investigação em indivíduos sem-abrigo, e apesar das limitações inerentes a este estudo, esperamos ter dado um contributo para alargar o conhecimento deste complexo fenómeno, nomeadamente no que respeita à caracterização psicológica destes indivíduos. / The homeless population and all the related issues such as poverty and social exclusion are a complex and increasingly worrying concern of our society. The multifaceted phenomenon of homelessness is a serious social problem. The relevance of this study relates to the scarcity of research on the homeless population and to better understand its complexity, particularly the psychological characteristics of the homeless individuals. As such, this study aims to better understand this population by collecting information on their fears, values, pleasures, perception of the reason for their situation, consumption of psychotropic substances, contact with family and friends. Simultaneously we intend to evaluate the feelings of shame (due to early negative experiences), paranoia and negative emotions (depression, anxiety and stress) in this specific population as well as analyse the relationship between these variables. The study sample is based on 56 individuals in the condition of homelessness, mostly male (n = 49), with an average age of 40.86 and 7 years of schooling. In addition to the psychological questionnaire developed for this purpose, the evaluation protocol also included scales to measure Depression, Anxiety and Stress (DASS-21), External Shame (OAS), Internal Shame (ISS) and Paranoia (GPS). The data in our study allowed to highlight some of the most significant problems of homelessness, including disruption of family ties, unemployment, drug abuse and others. We learnt that the homeless in our sample have a higher average number of paranoia, internal and external shame, when compared to the normal population. We have also found that the more educated our sample is, the less are the depressive symptoms and stress-related features. Among the studied variables, we have found significant positive and moderate correlations. Given the scarcity of research on homeless individuals and despite the limitations of this study, we hope to have contributed to increase the knowledge on this complex phenomenon, especially concerning the psychological characterization of these individuals.

A representação social do papel de gestores em organizações não governamentais

The discussions concerning the absence of a management model appropriate to the peculiarities of third sector organizations have not been impeditive to their emphasized expansion in the last decades. In the attempt of understanding this phenomenon from the perspective of those who manage social organizations, this work based on the theory of social representations to understand the notion that organization managers of the third sector - based in Fortaleza CE - have of the part that they play and how this notion influences the direction of their activities. Social representations of managers of four different categories of non-governmental organizations have been investigated, each category composed of two unities. The categories researched were: social integration through art and education, prevention and treatment of alcohol and drug abuse, children s health assistance and community action. By using Doise s Societal Approach, the role of social managers translated in intraindividual, interindividual and situational processes of their actions, has been analysed within the social representations, focusing on beliefs, values, symbols and stories that give meaning to the existence of non-governmental organizations. Analysis and discussion of data displayed the existence of diversity in the understanding of managers within their practice, in other words, the management profile is also its own manager s. The branch where an organization acts is also preponderant in the shaping of a management style. It could be deduced, from to the organizations researched, that professional formation and the manager s social insertion mainly, are determinative factors in the outlining of a management model of its own. It was concluded that, due to heterogeneity of interests and action segments, there is no systematic process for social management among organizations. Management styles are supported by their director s own perception of achievement, who model organizations according to their contingencies

Toxicodependência e a Medicina Dentária

Introdução: com o aumento da toxicodependência, que engloba um problema mundial, também cresce o número de doentes com suas devidas consequências, que são patologias sistémicas, englobando a saúde oral, que é uma das partes do corpo que mais sofre com a toxicodependência. Objetivos: Esta tese tem como objetivo a revisão da literatura sobre “toxicodependência” e “medicina dentária”, correlacionando estes temas com patologias e complicações na cavidade oral, nomeadamente, bruxismo, desgaste dental, xerostomia, halitose, cárie rampante e doença periodontal. Metodologia: Foi realizada uma revisão bibliográfica com base em artigos publicados em revistas e teses disponíveis em bibliotecas online, nos últimos dez anos. As palavraschaves usadas foram, assim como a conjugação entre elas e seus devidos idiomas: toxicodependência, desintoxicação, abstinência, cannabis, álcool, metanfetamina, heroína, opiáceos, tabaco, nicotina, metadona, erosão dentária, xerostomia, cáries, bruxismo, entre outras. Conclusão: Preconiza-se que haja uma maior atenção e conhecimento por parte do médico dentista sobre esta condição, bem como das complicações associadas, uma vez que é um dos principais profissionais de saúde a ter o contacto e a oportunidade de tratar os pacientes sintomáticos, como também os que estão em fase de recuperação e reinserção social.

An investigation into the suitability of time-of-flight mass spectrometry in forensic toxicology

Liquid chromatography coupled with mass spectrometry is one of the most powerful tools in the toxicologist’s arsenal to detect a wide variety of compounds from many different matrices. However, the huge number of potentially abused substances and new substances especially designed as intoxicants poses a problem in a forensic toxicology setting. Most methods are targeted and designed to cover a very specific drug or group of drugs while many other substances remain undetected. High resolution mass spectrometry, more specifically time-of-flight mass spectrometry, represents an extremely powerful tool in analysing a multitude of compounds not only simultaneously but also retroactively. The data obtained through the time-of-flight instrument contains all compounds made available from sample extraction and chromatography, which can be processed at a later time with an improved library to detect previously unrecognised compounds without having to analyse the respective sample again. The aim of this project was to determine the utility and limitations of time-of-flight mass spectrometry as a general and easily expandable screening method. The resolution of time-of-flight mass spectrometry allows for the separation of compounds with the same nominal mass but distinct exact masses without the need to separate them chromatographically. To simulate the wide variety of potentially encountered drugs in such a general screening method, seven drugs (morphine, cocaine, zolpidem, diazepam, amphetamine, MDEA and THC) were chosen to represent this variety in terms of mass, properties and functional groups. Consequently, several liquid-liquid and solid phase extractions were applied to urine samples to determine the most general suitable and unspecific extraction. Chromatography was optimised by investigating the parameters pH, concentration, organic solvent and gradient of the mobile phase to improve data obtained by the time-of-flight instrument. The resulting method was validated as a qualitative confirmation/identification method. Data processing was automated using the software TargetAnalysis, which provides excellent analyte recognition according to retention time, exact mass and isotope pattern. The recognition of isotope patterns allows excellent recognition of analytes even in interference rich mass spectra and proved to be a good positive indicator. Finally, the validated method was applied to samples received from the A& E Department of Glasgow Royal Infirmary in suspected drug abuse cases and samples received from the Scottish Prison Service, which we received from their own prevalence study targeting drugs of abuse in the prison population. The obtained data was processed with a library established in the course of this work.
