RESUMO
BACKGROUND: Non-Hodgkin lymphoma (NHL) is the most common cancer in people with HIV. Although 95% of HIV patients are in developing countries like Peru, the majority of these studies have been conducted in developed countries. In this study we aim to evaluate prognostic factors associated with outcomes in HIV positive patients undergoing systemic therapy for treatment of NHL. METHODS: This retrospective study includes patients with NHL seen in the Instituto Nacional de Enfermedades Neoplasicas (INEN) between 2004 to 2014. Patients were divided into two groups: antiretroviral therapy (ART) -naïve (n = 34) and those previously treated, ART-exposed (n = 13), at the time of diagnosis. All patients received chemotherapy and ART. The medical records were reviewed. Data were analyzed using t-test and chi-square test. Survival curves were estimated by the Kaplan-Meier method and comparison was done by log-rank test. Multivariate analysis for overall survival (OS) was performed with the Cox proportional hazard regression model. RESULTS: All ART-exposed patients were from the capital city (p = 0.039); they had significantly lower hemoglobin levels compared to ART-naïve patients (p = 0.026). The median OS was 47.7 months with a 5-yr OS of 36.1%. The median OS for ART naïve patients was significantly higher than that for ART-exposed patients (57.05 and 21.09 months, respectively; p = 0.018). Advanced stage and low serum albumin were associated with lower OS in both groups. Age > 60 was associated with worse outcomes in the ART-naïve cohort. CONCLUSIONS: Advanced stage, low serum albumin and previous ART treatment were the primary prognostic factors associated with poorer outcomes in patients with NHL and HIV infection. In ART-naïve patients, age > 60 was associated with worse outcomes but in this cohort, older patients still had better overall outcomes than ART-exposed patients.
RESUMO
Abstract The search for strategies for the reduction of Surgical Site infection (SSI) is a priority, given the impact those infections have on the outcome of the patients. The preope rative patient skin antisepsis, has recently gained greater significance in the prevention of SSI, as one of the critical factors, which can be intervened and can reduce the risk of infection. In recent years, comprehensive investigations have been published, not only dedicated to the comparison of antiseptic solutions, application techniques, but also about the importance of preoperative washing, use of surgical tapes and dressings impregnated with antiseptics, and preoperative shaving. This review outlines the key findings related to the preoperative patient's skin antisepsis and offers a protocol with practical recommendations to be implemented in the institutions of our country. It provides evidence based recommendations about the use of antiseptic solutions (povidone iodine, chlorhexidine, chlorhexidine plus alcohol, etc.) with emphasis on the advantages and disadvantages of each one.

La búsqueda de estrategias para la disminución de la infección de sitio operatorio (ISO) es una prioridad, dado el impacto que ésta tiene en los resultados de la atención de los pacientes. Recientemente ha tomado gran relevancia en la prevención de la ISO, la preparación prequirúrgica de la piel del paciente como uno de los factores clave, en los que se puede intervenir y disminuir el riesgo. En los últimos años han aparecido revisiones exhaustivas dedicadas no solo a la comparación de las soluciones antisépticas, y técnica de aplicación, también acerca de la importancia del baño pre operatorio, uso de cintas y compresas quirúrgicas impregnadas con antisépticos y el recorte de cabello preoperatorio. En esta publicación se describen los hallazgos más importantes relacionados con la preparación antiséptica de la piel del paciente y se propone un protocolo con recomendaciones prácticas para ser implementado en las instituciones del país. Se incluyen recomendaciones basadas en niveles de evidencia sobre el uso de las soluciones antisépticas (yodopovidona, clorhexidina, clorhexidina mas alcohol, entre otras) con énfasis en las ventajas y desventajas de cada una de ellas.
