Évaluation logique de trois (3) campagnes de prévention contre le VIH/Sida à Montréal

À l’heure où nous écrivons, l’ONU enregistre 33 million de personnes touchées par le VIH/Sida. Dans les perspectives actuelles de lutte contre la propagation de la pandémie, plusieurs moyens peuvent être mis en place : utilisation du condom, dépistage, échange de seringues, abstinence… Mais une question se pose : quels éléments nous influencent dans l’utilisation d’une telle ou telle pratique? Faisant usage des stratégies de marketing social, les campagnes de prévention contre le VIH/Sida mettent l’emphase sur l’empowerment des individus face à leur prise de risque. Par ce biais, on tente de changer certains comportements et d’en adopter de nouveaux plus sécuritaires pour la santé. Nous avons évalué ici trois (3) campagnes de prévention contre le VIH/Sida à Montréal. Le but de cette recherche a été de distinguer les éléments pouvant faciliter la planification des campagnes dans une perspective de diminution de l’incidence du VIH/Sida. Lors de la prise de décisions concernant l'évaluation d'une campagne de prévention de lutte contre le VIH/Sida, plusieurs points fondamentaux sont à considérer : la source de l’information, le message, le canal utilisé, les caractéristiques du récepteur et l’effet désiré par la campagne. Ces aspects sont primordiaux dans la prise de conscience de la campagne. Mais attention, ce type d'évaluation n'est pas conçu pour en démontrer son efficacité. Notre étude nous confirme l’importance de l’évaluation des campagnes de prévention aux différents stades de leurs conceptions. Cette recherche nous pousse à connaître les détails du programme de prévention et ainsi avoir une bonne compréhension du déroulement de l'intervention dans une perspective future d’en expliquer l’efficacité

Caracterización de la población con bronquiolitis en la Clínica infantil Colsubsidio en el año 2013

Introducción: La bronquiolitis es la infección viral más común del tracto respiratorio en menores de 2 años. En Colombia existen pocos estudios respecto a este tema, lo cual nos motivó a realizar un estudio para evaluar el panorama actual de la población Colombiana. Objetivo: Caracterizar la población hospitalizada con diagnóstico de bronquiolitis en la Clínica Infantil Colsubsidio Materiales y Método: Es un estudio descriptivo – retrospectivo donde se revisaron variables demográficas, clínicas, paraclínicas y de tratamiento, en las historias clínicas de pacientes hospitalizados con bronquiolitis en la Clínica Infantil Colsubsidio. Resultados: Se evaluaron 1230 historias, 906 cumplieron criterios de inclusión. Un 55,7% fueron niños. La edad promedio fue de 5,5 meses. El principal factor de riesgo fue ser pretérmino (57%). El principal germen aislado fue el Virus Sincitial Respiratorio, seguido por el adenovirus. En cuanto al manejo, el medicamento más utilizado fue el salbutamol en el 98%, con un uso de antibióticos en el 25%, siendo la razón de su uso la sospecha de coinfección bacteriana. El 65,78% tuvo una estancia hospitalaria menor a 5 días y el 3,64% requirió ingreso a la Unidad de Cuidados intensivos. La mortalidad fue 0%. Conclusión: Las características demográficas de nuestra población, el comportamiento de la enfermedad, requerimiento de UCI y la estancia hospitalaria son similares a los descritos en la literatura mundial. Evidenciamos un gran número de ayudas diagnósticas y uso de medicamentos, que obliga a replantearnos el manejo que damos y adherirnos a la evidencia actual

Assistência aos portadores de úlceras venosas: proposta de protocolo

Venous ulcers (VU), recurrent chronic wounds resulting from Chronic Venous Insufficiency (CVI), affect different age groups and would severely affect ambulation of patients. The lesions require treatment lasting and complex and are responsible for significant morbidity and mortality. Thus, this study aims to identify the important aspects covered in the scientific literature protocol for assisting patients with venous ulcers, identifying the issues to be proposed by the judges of the study (nurses, doctors and physiotherapists) to the protocol of care provided to patients venous ulcers and present the structure of protocol proposed by the judges of the study to assist patients with venous ulcers treated at a referral hospital of Rio Grande do Norte. This is a descriptive study using a quantitative approach, carried out at the dressings, located in the outpatient surgical clinic of the Hospital University Onofre Lopes (HUOL), located in East Sanitary District, Natal-RN. The sample consisted of 39 professionals, 30 nurses, seven doctors and two physical therapists, team members HUOL surgical clinic and other public and private institutions of Rio Grande do Norte and Jequié/Bahia. These professionals were the judges responsible for selecting the guidelines already proposed in the literature on VU protocols. Approved by the Ethics in Research HUOL (Report n.o 081/07), began the first stage of the study which consisted of reviewing the scientific literature about the relevant aspects to be included in a protocol for assisting patients with VU. These aspects were organized into a proposed questionnaire to the judges of the study. Following examination, held on the content validation with application of the Kappa (K), accepting a score higher than 0.80 and the Likert Scale, whereas rates from 4.0 to 5.0. The data collected were organized in Microsoft Excel and exported into Statistical Package for Social Sciences (SPSS) 15.0. The literature review included national and international scientific articles, thesis, dissertation and institutional protocols. Regarding the characterization of professional nurses predominated (76.1%), between 34 and 45 years (41.0%), female (79.5%), married/consensual union (46.2%), with specialization in VU care (61.5%), working in the hospital network (46.1%), with up to 5 years experience in VU (69.2%) and claiming to feel prepared to care for these injuries (92.3 %). With regard to aspects that had very good agreement (K ≥ 0.81), remained the items found in the literature with some modifications. In the analysis of the proposed evaluation items had very important, ranging from 4.1 (drug treatment) to 4.9 (patient assessment and care of the injury and the injured and perilesional skin). The proposition of the protocol is arranged in eleven items: A) Evaluation of patient and lesion, B) Registration and documentation, C) the wound and perilesional skin, D) an indication of coverage, E) Use of antibiotic and pain treatment, F) Surgical treatment of CVI, G) Drug treatment, H) Improving venous return and prevetion of recurrence, I) Referral of patients, J) Training and K) Reference and counter reference

Tumor infiltrating lymphocytes in ovarian cancer.

Several improvements in ovarian cancer treatment have been achieved in recent years, both in surgery and in combination chemotherapy with targeting. However, ovarian tumors remain the women's cancers with highest mortality rates. In this scenario, a pivotal role has been endorsed to the immunological environment and to the immunological mechanisms involved in ovarian cancer behavior. Recent evidence suggests a loss of the critical balance between immune-activating and immune-suppressing mechanisms when oncogenesis and cancer progression occur. Ovarian cancer generates a mechanism to escape the immune system by producing a highly suppressive environment. Immune-activated tumor infiltrating lymphocytes (TILs) in ovarian tumor tissue testify that the immune system is the trigger in this neoplasm. The TIL mileau has been demonstrated to be associated with better prognosis, more chemosensitivity, and more cases of optimal residual tumor achieved during primary cytoreduction. Nowadays, scientists are focusing attention on new immunologically effective tumor biomarkers in order to optimize selection of patients for recruitment in clinical trials and to identify relationships of these biomarkers with responses to immunotherapeutics. Assessing this point of view, TILs might be considered as a potent predictive immunotherapy biomarker.
