ABSTRACT
The study aims to identify percutaneous injuries correlates in the nursing team from a Brazilian tertiary-care hospital. A case-control study was conducted from January 2003 to July 2004, including 200 cases and 200 controls. Cases and controls were paired by gender, professional category, and work section. To evaluate the relationship between potential risk/protective factors and the outcome, odds ratios were estimated, using multivariate logistic regression methods. The results shown six predictors of percutaneous injuries: "recapping needles" (OR 9.48; CI(95 percent): 5.29-16.96); "hours worked per week > 50 hours" (OR 2.47; CI(95 percent): 1.07-5.67); "years in nursing practice < 5 years" (OR 6.70; CI(95 percent): 2.42-18.53); "work shift in night" (OR 2.77; CI(95 percent): 1.35-5.70); "low self evaluation of risk" (OR 10.19; CI(95 percent): 3.67-28.32) and "previous percutaneous injuries" (OR 3.14; CI(95 percent): 1.80-5.48). The results support the recommendation of applying effective strategies to prevent percutaneous injuries in the nursing team working on tertiary-care institutions.
La finalidad del estudio fue identificar factores asociados a los accidentes percutáneos en el equipo de enfermería de un hospital terciario. Un estudio caso-control fue conducido entre enero de 2003 y julio de 2004, con selección de 200 casos y 200 controles, emparejados según género, categoría profesional y sector de trabajo. Las medidas de asociación utilizadas fueron las razones de momios, estimados mediante la regresión logística multivariada. Seis predictores para los accidentes percutáneos fueron identificados: "reencapsular agujas" (OR 9.48; CI(95 por ciento): 5.29-16.96); "jornada semanal > 50 horas" (OR 2.47; CI(95 por ciento): 1.07-5.67); "experiencia en la enfermería < 5 años" (OR 6.70; CI(95 por ciento): 2.42-18.53); "trabajar en jornada nocturna" (OR 2.77; CI(95 por ciento): 1.35-5.70); "auto-evaluar como bajo el riesgo de accidentes" (OR 10.19;CI(95 por ciento): 3.67-28.32) y "accidentes percutáneos previos" (OR 3.14; CI(95 por ciento): 1.80-5.48). Los resultados permiten la recomendación de estrategias efectivas para la prevención de accidentes percutáneos en el equipo de enfermería de hospitales terciarios.
O estudo teve por objetivo identificar fatores associados aos acidentes percutâneos na equipe de enfermagem de um hospital terciário. Um estudo caso-controle foi conduzido entre janeiro de 2003 a julho de 2004, com seleção de 200 casos e 200 controles, emparelhados segundo gênero, categoria profissional e setor de trabalho. As medidas de associação utilizadas foram os odds ratios, estimados por meio da regressão logística multivariada. Seis preditores para os acidentes percutâneos foram identificados: "reencapar agulhas" (OR 9.48; CI(95 por cento): 5.29-16.96); "jornada semanal > 50 horas" (OR 2.47; CI(95 por cento): 1.07-5.67); "experiência na enfermagem < 5 anos" (OR 6.70; CI(95 por cento): 2.42-18.53); "trabalhar em jornada noturna" (OR 2.77; CI(95 por cento): 1.35-5.70); "auto-avaliar como baixo o risco de acidentes" (OR 10.19;CI(95 por cento): 3.67-28.32) e "acidentes percutâneos prévios" (OR 3.14; CI(95 por cento): 1.80-5.48). Os resultados permitem a recomendação de estratégias efetivas para a prevenção de acidentes percutâneos na equipe de enfermagem de hospitais terciários.

Objective To quantitatively evaluate the metabolic changes of prostate adenocarcinoma using magnetic resonance spectroscopy (MRS).Methods Eighteen patients of prostate cancer proved by ultrasound guided systemic biopsy were enrolled in this study.All the puncture locations were marked and the corresponding (Choline+Creatine)/Citrate ratios were calculated on the basis of the MRS metabolic map.Results 204 samples were obtained and 106 of them were diagnosed as cancer.The average (Cho+Cre)/Cit ratio in the 106 positions was 2.53?1.02.The (Cho+Cre)/Cit ratio of cancer area was statistically higher than that of noncancerous area (F=8.64, P
