Tratamento do Centro de Atenção Psicossocial para usuários de álcool e outras drogas CAPSad II Leste Natal/RN : uma avaliação da efetividade

The treatment for abusive users of alcohol and other drugs suffered significant modifications until arriving to the psychosocial model that is used by Centro de Atenção Psicossocial CAPSad II Eastern Natal/RN (Psychosocial Support Center). That model appears starting from Brazilian sanitary and psychiatric reforms which are expressed in the principles and propositions of Sistema Único de Saúde SUS (Unique System of Health). The Psychiatric Reform meant a rupture with the mental hospital and hospital centered treatment pattern which was destined to the abusive users of alcohol and other drugs. The new proposal offers the universalization, democratization, regionalization and completeness of the actions in the field of mental health. It gathers a strictly interdisciplinary health staff. The purpose of this study is to evaluate the effectiveness of the treatment for abusive users of alcohol and other drugs offered by CAPSad II Eastern Natal/RN. The evaluation used, as priority, the qualitative social research through an evaluating study starting from the non-experimental model. The methodological process used different instruments of data collection: bibliographical and documental researches, systematic observations at CAPSad II Eastern Natal/RN and, mainly, the semistructured interviews (21) that were accomplished with the professionals, users and relatives of CAPSad II Eastern Natal/RN. The investigation showed the effectiveness of the service and, therefore, CAPSad II Eastern Natal/RN constitute itself as the main confronting strategy to the mental hospital and hospital centered treatment pattern of caring the abusive users of alcohol and other drugs

Effectiveness of interventions targeting frequent users of emergency departments: a systematic review

L'article publié de le cadre de cette thèse est intitulé "Effectiveness of interventions targeting frequent users of emergency departments: A systematic review." Il a été publié par les "Annals of Emergency Medicine (AEM)" en juillet 2011. Le titre en français pourrait être: "Efficacité des interventions ciblant les utilisateurs fréquents des services d'urgence: Une revue systématique." Le titre du journal américain pourrait être: "Annales de Médecine d'Urgence". Il s'agit du journal du "Collège Américain des Médecins d'Urgence", en anglais "American College of Emergency Physicians (ACEP)". L'article a été soumis à l'AEM en raison de l'intérêt que ses rédacteurs en chef portent pour le sujet des utilisateurs fréquents des services d'urgence, démontré depuis plus de dix ans par la publication de nombreux articles dans ce domaine. Le facteur d'impact de l'AEM est de surcroît le plus important des journaux d'urgence, assurant ainsi une large diffusion des articles publiés. Lors de sa publication, l'article a été accompagné d'un éditorial signé par le Docteur Maria C. Raven, médecin au Centre Hospitalier de Bellevue à New York, Etats-Unis.¦Contexte et enjeux¦La Direction Générale du Centre Hospitalier Vaudois (CHUV) finance, dans le cadre du plan stratégique 2009-2013, un axe "populations vulnérables". Cet axe est porté en grande partie par des projets développés au sein de la Policinlique Médicale Universitaire et l'Unité des Populations Vulnérables qui prend en charge, enseigne la prise en charge et s'interroge sur la prise en charge des personnes les plus vulnérables. C'est dans ce contexte que nous avons été amenés à réfléchir à l'existence éventuelle de marqueurs de vulnérabilité; l'utilisation fréquente des services d'urgence par certains individus constitue à n'en pas douter l'un de ces marqueurs. Il existe une importante littérature décrivant en détail ces utilisateurs fréquents des services d'urgence, raison pour laquelle nous avons décidé de faire un pas supplémentaire et de nous interroger sur l'efficacité des interventions (quelle qu'elles soient) ciblant cette population particulière. Nous avons ainsi entrepris une revue systématique de la littérature scientifique médicale et sociale pour approfondir cette question, et c'est précisément le résultat de cette recherche qui constitue ce travail de thèse.¦Conclusions et perspectives¦Les utilisateurs fréquents des services d'urgence sont des individus particulièrement vulnérables, et ce aussi bien aux Etats-Unis, qu'en Europe ou en Australie: ils présentent par exemple une mortalité supérieure aux autres utilisateurs des urgences; ils sont également plus à risque de présenter une consommation abusive d'alcool ou de drogues, une maladie mentale, ou une maladie chronique. Ils sont plus souvent sans abri, sans assurance et d'un statut socio-économique bas.¦De nombreuses interventions on été développées pour prendre en charge les utilisateurs fréquents des urgences. Le but de ces interventions est d'une part de réduire la consommation des services d'urgence et d'autre part d'améliorer la santé au sens large de ces patients vulnérables. C'est en ces termes (réduction de la fréquence d'utilisation des services d'urgence et amélioration de la santé) que l'efficacité d'une intervention est mesurée.¦Parmi l'ensemble des interventions étudiées, l'une semble particulièrement efficace pour réduire le nombre de visites aux urgences et améliorer un certain nombre de marqueurs sociaux (accès à un logement ou à une assurance-maladie). Cette intervention est appelée "case management" (ou "gestion de cas", difficile tentative de traduction de ce concept en français), et consiste en une approche multidisciplinaire (médecins, infirmiers, assistants sociaux) fournissant un service individualisé, dans le cadre de l'hôpital et souvent également dans la communauté. L'approche consiste à évaluer les besoins précis du patient, à l'accompagner dans son parcours de soin, à l'orienter si nécessaire et à mettre en place autour de lui un réseau communiquant de manière adaptée.¦Le "case management" ayant montré son efficacité dans la prise en charge des utilisateurs fréquents des services d'urgence, y-compris en termes de coûts, notre conclusion va dans le sens d'encourager les hôpitaux à évaluer l'importance de ce phénomène dans leur propre pratique et à mettre en place des équipes de prise en charge de ces patients, dans le double but de soutenir des patients particulièrement vulnérables et de réduire la consommation des services d'urgence. Suite à la réflexion suscitée par ce travail de thèse, une telle équipe a été mise en place en 2010, dans un cadre de recherche-action, au niveau du CHUV. Ce projet est dirigé par le Dr Patrick Bodenmann, responsable de l'Unité Populations Vulnérables de la Policlinique Médicale Universitaire de Lausanne. Le Dr Bodenmann est également le directeur de cette thèse et le dernier auteur de la revue systématique.

Exploratory Study Of The Effect Of Lifestyle Counselling On Bone Mineral Density And Body Composition In Users Of The Contraceptive Depot-medroxyprogesterone Acetate.

To compare variations in bone mineral density (BMD) and body composition (BC) in depot-medroxyprogesterone acetate (DMPA) users and nonusers after providing counselling on healthy lifestyle habits. An exploratory study in which women aged 18 to 40 years participated: 29 new DMPA users and 25 new non-hormonal contraceptive users. All participants were advised on healthy lifestyle habits: sun exposure, walking and calcium intake. BMD and BC were assessed at baseline and 12 months later. Statistical analysis included the Mann-Whitney test or Student's t-test followed by multiple linear regression analysis. Compared to the controls, DMPA users had lower BMD at vertebrae L1 and L4 after 12 months of use. They also had a mean increase of 2 kg in total fat mass and an increase of 2.2% in body fat compared to the non-hormonal contraceptive users. BMD loss at L1 was less pronounced in DMPA users with a calcium intake ≥ 1 g/day compared to DMPA users with a lower calcium intake. DMPA use was apparently associated with lower BMD and an increase in fat mass at 12 months of use. Calcium intake ≥ 1 g/day attenuates BMD loss in DMPA users. Counselling on healthy lifestyle habits failed to achieve its aims.

[adherence To Statin Treatment And Associated Factors In Female Users From The Unified Health System (sus)].

To identify the adherence rate of a statin treatment and possible related factors in female users from the Unified Health System. Seventy-one women were evaluated (64.2 ± 11.0 years) regarding the socio-economic level, comorbidities, current medications, level of physical activity, self-report of muscular pain, adherence to the medical prescription, body composition and biochemical profile. The data were analyzed as frequencies, Chi-Squared test, and Mann Whitney test (p<0.05). 15.5% of women did not adhere to the medical prescription for the statin treatment, whose had less comorbidities (p=0.01), consumed less quantities of medications (p=0.00), and tended to be younger (p=0.06). Those patients also presented higher values of lipid profile (CT: p=0.01; LDL-c: p=0.02). Musculoskeletal complains were not associated to the adherence rate to the medication. The associated factors to adherence of dyslipidemic women to statin medical prescription were age, quantity of comorbidities and quantity of current medication.

Weight Variation In Users Of Depot-medroxyprogesterone Acetate, The Levonorgestrel-releasing Intrauterine System And A Copper Intrauterine Device For Up To Ten Years Of Use.

Data on record regarding weight variation in depot-medroxyprogesterone acetate (DMPA) and levonorgestrel-releasing intrauterine system (LNG-IUS) users are controversial. To date, no studies have yet evaluated weight variation in DMPA and LNG-IUS users in up to ten years of use compared to non-hormonal contraceptive users. A retrospective study analysed weight variations in 2138 women using uninterruptedly DMPA (150 mg intramuscularly, three-monthly; n = 714), the LNG-IUS (n = 701) or a copper-intrauterine device (Cu-IUD; n = 723). At the end of the first year of use, there was a mean weight increase of 1.3 kg, 0.7 kg and 0.2 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively, compared to weight at baseline (p < 0.0001). After ten years of use, the mean weight had risen by 6.6 kg, 4.0 and 4.9 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively. DMPA-users had gained more weight than LNG-IUS- (p = 0.0197) and than Cu-IUD users (p = 0.0294), with the latter two groups not differing significantly from each other in this respect (p = 0.5532). Users of hormonal and non-hormonal contraceptive methods gained a significant amount of weight over the years. DMPA users gained more weight over the treatment period of up to ten years than women fitted with either a LNG-IUS or a Cu-IUD.

High Prevalence Of Insulin Resistance Assessed By The Glucose Clamp Technique In Hormonal And Non-hormonal Contraceptive Users.

Objective To assess the prevalence of insulin resistance (IR) and associated factors in contraceptive users. Methods A total of 47 women 18 to 40 years of age with a body mass index (kg/m(2)) < 30, fasting glucose levels < 100 mg/dl and 2-hour glucose level < 140 mg/dl after a 75-g oral glucose load were submitted to a hyperinsulinemic-euglycemic clamp. The women were distributed in tertiles regarding M-values. The analysed variables were use of combined hormonal/non-hormonal contraception, duration of use, body composition, lipid profile, glucose levels and blood pressure. Results IR was detected in 19% of the participants. The women with low M-values presented significantly higher body fat mass, waist-to-hip ratio, fasting insulin, HOMA-IR and were nulligravida, showed > 1 year of contraceptive use and higher triglyceride levels. IR was more frequent among combined oral contraceptive users, however no association was observed after regression analysis. Conclusions The prevalence of IR was high among healthy women attending a family planning clinic independent of the contraceptive method used with possible long-term negative consequences regarding their metabolic and cardiovascular health. Although an association between hormonal contraception and IR could not be found this needs further research. Family planning professionals should be proactive counselling healthy women about the importance of healthy habits.

Operant measurement of auditory threshold in prelingually deaf users of cochlear implants: II

Two experiments evaluated an operant procedure for establishing stimulus control using auditory and electrical stimuli as a baseline for measuring the electrical current threshold of electrodes implanted in the cochlea. Twenty-one prelingually deaf children, users of cochlear implants, learned a Go/No Go auditory discrimination task (i.e., pressing a button in the presence of the stimulus but not in its absence). When the simple discrimination baseline became stable, the electrical current was manipulated in descending and ascending series according to an adapted staircase method. Thresholds were determined for three electrodes, one in each location in the cochlea (basal, medial, and apical). Stimulus control was maintained within a certain range of decreasing electrical current but was eventually disrupted. Increasing the current recovered stimulus control, thus allowing the determination of a range of electrical currents that could be defined as the threshold. The present study demonstrated the feasibility of the operant procedure combined with a psychophysical method for threshold assessment, thus contributing to the routine fitting and maintenance of cochlear implants within the limitations of a hospital setting.

Dependência de Internet e de jogos eletrônicos: uma revisão

OBJETIVO: Com a inclusão das novas tecnologias contemporâneas, a Internet e os jogos eletrônicos tornaram-se ferramentas de uso amplo e irrestrito, transformando-se em um dos maiores fenômenos mundiais da última década. Diversas pesquisas atestam os benefícios desses recursos, mas seu uso sadio e adaptativo progressivamente deu lugar ao abuso e à falta de controle ao criar severos impactos na vida cotidiana de milhões de usuários. O objetivo deste estudo foi revisar de forma sistemática os artigos que examinam a dependência de Internet e jogos eletrônicos na população geral. Almejamos, portanto, avaliar a evolução destes conceitos no decorrer da última década, assim como contribuir para a melhor compreensão do quadro e suas comorbidades. MÉTODO: Foi feita uma revisão sistemática da literatura através do MedLine, Lilacs, SciELO e Cochrane usando-se como parâmetro os termos: "Internet addiction", pathological "Internet use", "problematic Internet use", "Internet abuse", "videogame", "computer games" e "electronic games". A busca eletrônica foi feita até dezembro de 2007. DISCUSSÃO: Estudos realizados em diferentes países apontam para prevalências ainda muito diversas, o que provavelmente se deve à falta de consenso e ao uso de diferentes denominações, dando margem à adoção de distintos critérios diagnósticos. Muitos pacientes que relatam o uso abusivo e dependência passam a apresentar prejuízos significativos na vida profissional, acadêmica (escolar), social e familiar. CONCLUSÕES: São necessárias novas investigações para determinar se esse uso abusivo de Internet e de jogos eletrônicos pode ser compreendido como uma das mais novas classificações psiquiátricas do século XXI ou apenas substratos de outros transtornos.

Organ donation: Acceptance and refusal among users of the public health system from Brazil

The present study sought to identify the perception of a given group of users of the Brazilian Public Health System (Sistema Unico de Saude) regarding organ donation and to implement an educational policy. Structured interviews were conducted with the aim of describing the profile of donor and nondonor subjects, the importance of organ donation, and the knowledge regarding donation and brain death. One hundred subjects were interviewed: 33% of them considered themselves potential donors; 40% were donors; 13% were nondonors; and 14% were ill-informed potential donors. However, only 40% of users have already officially expressed to their families a willingness to donate. Regarding their knowledge about the propitious moment for organ donation, only 64% of them associated the donation act with brain death. Although the present results revealed that users of the Brazilian Public Health System are prone to organ donation, there actually was a high amount of refusals, which may be due to lack of information and knowledge regarding the donation-transplantation process.

Fate of Surface-Inoculated Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella Typhimurium on Kippered Beef during Extended Storage at Refrigeration and Abusive Temperatures

The behavior of Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella Typhimurium on kippered beef was evaluated. Individual pieces of the product were separately inoculated on the top and bottom surfaces with each three- to six-strain pathogen cocktail at ca. 6.0 log CFU per piece and stored at 4, 10, 21, or 30 degrees C for up to 28 days in each of two trials. When kippered beef was inoculated with E coli O157:H7, Salmonella Typhimurium, or L. monocytogenes and stored at 4, 10, 2 1, or 30 degrees C for up to 28 days, pathogen numbers decreased ca. 0.4 to 0.9, 1.0 to 1.8, 3.0 to >= 5.25, and >= 5.0 to 5.25 log CFU per piece, respectively. Average D-values for E. coli O157:H7, Salmonella Typhimurium, and L. monocytogenes stored at 4 to 30 degrees C for 28 days were ca. 41 to 4.6, 40.8 to 5.3, and 29.5 to 4.3 days, respectively. As expected, the higher the storage temperature, the greater the level and rate of inactivation for all three pathogens. These data establish that kippered beef does not provide an environment conducive to proliferation of these pathogens.

Abnormal Neurovascular Control in Anabolic Androgenic Steroids Users

NUNES ALVES, M. J. N., M. R. DOS SANTOS, R. G. DIAS, C. A. AKIHO, M. C. LATERZA, M. U. P. B. RONDON, R. L. DE MORAES MOREAU, and C. E. NEGRAO. Abnormal Neurovascular Control in Anabolic Androgenic Steroids Users. Med. Sci. Sports Exerc., Vol. 42, No. 5, pp. 865-871, 2010. Purpose: Previous studies showed that anabolic androgenic steroids (AAS) increase vascular resistance and blood pressure (BP) in humans. In this study, we tested the hypotheses 1) that AAS users would have increased muscle sympathetic nerve activity (MSNA) and reduced forearm blood flow (FBF) compared with AAS nonusers and 2) that there would be an association between MSNA and 24-h BP. Methods: Twelve AAS users aged 31 +/- 2 yr (means +/- SE) and nine age-matched AAS nonusers aged 29 T 2 yr participated in the study. All individuals were involved in strength training for at least 2 yr. AAS was determined by urine test (chromatography-mass spectrometry). MSNA was directly measured by microneurography technique. FBF was measured by venous occlusion plethysmography. BP monitoring consisted of measures of BP for 24 h. Results: MSNA was significantly higher in AAS users than that in AAS nonusers (29 +/- 3 vs 20 +/- 1 bursts per minute, P = 0.01). FBF (1.92 +/- 0.17 vs 2.77 +/- 0.24 mL.min(-1).100 mL(-1), P = 0.01) and forearm vascular conductance (2.01 +/- 0.17 vs 2.86 +/- 0.31 U, P = 0.02) were significantly lower in AAS users than that in AAS nonusers. Systolic (131 +/- 4 vs 120 +/- 3 mm Hg, P = 0.001), diastolic (74 +/- 4 vs 68 +/- 3 mm Hg, P = 0.02), and mean BP (93 +/- 4 vs 86 +/- 3 mm Hg, P = 0.005) and heart rate (74 +/- 3 vs 68 +/- 3 bpm, P = 0.02) were significantly higher in AAS users when compared with AAS nonusers. Further analysis showed that there was a significant correlation between MSNA and 24-h mean BP (r = 0.75, P = 0.002). Conclusions: AAS increases MSNA and reduces muscle blood flow in young individuals. In addition, the increase in BP levels in AAS users is associated with augmented sympathetic outflow. These findings suggest that AAS increases the susceptibility for cardiovascular disease in humans.

Reputations, self-concepts and coping strategies of volatile solvent users

Data pertaining to the reputations, self-concepts and coping strategies of thirty-one secondary school Volatile Solvent Users (VSUs), forty-four ex-VSUs, and forty-eight non-VSUs in the Perth Metropolitan area of Western Australia were obtained using the High School Student Activity Questionnaire. Findings revealed that significant differences between current VSUs, ex-VSUs, and non-VSUs were more attributable to factors of reputation enhancement than to factors of either self-concept or coping strategies. Current VSUs identified themselves as both having and wanting to have a more non-confronting reputation, and as admiring drug-related activities significantly more than both ex-VSUs and non-VSUs. Two coping variables were also found to be significant indicating that females use more nonproductive coping strategies and external coping strategies than males. No interaction effects were identified. The implications for drug education and further research are discussed.
