RESUMO

OBJECTIVE: This study aimed to assess the population at risk of infection by extended-spectrum beta-lactamase (ESBL)-producing organisms, using clinical criteria. MATERIALS AND METHODS: All urine cultures positive for Enterobacteriaceae in a Spanish hospital department from January 2010 to 2014 were reviewed. All isolates with ESBL-positive strains were collected, and isolates received during the first week of each month with ESBL-negative strains from symptomatic patients hospitalized or admitted to the emergency room. Multivariate analysis of the factors involved was undertaken and a nomogram developed to predict the probability of infection by ESBL-producing microorganisms. RESULTS: The study included 1524 patients with urinary tract infection (UTI): 416 ESBL-positive and 1108 ESBL-negative. In univariate analysis, risk factors were: male gender (p = 0.036), age (p < 0.0001), nursing home (p < 0.0001), previous antimicrobial therapy (p < 0.0001) or hospitalization (p < 0.0001), diabetes (p < 0.0001), chronic renal insufficiency (p < 0.0001), severe underlying disease (p < 0.0001), neoplasia (p = 0.0005), urological (p < 0.0001) and non-urological invasive procedure (p = 0.0003), recurrent UTI (p < 0.0001), urological (p < 0.0001) or abdominal surgery (p < 0.0001) and permanent urethral catheter (p < 0.0001). In multivariate analysis, the data set was split into a development cohort of 1067 patients and a validation cohort of 457 cases. A nomogram was developed to predict the probability of infection by ESBL-producing bacteria, which included seven variables: age (p < 0.0001), gender (p = 0.004), nursing home (p < 0.0001), previous antimicrobial therapy (p = 0.04) or hospitalization (p < 0.0001), recurrent UTI (p < 0.0001) and non-urological invasive procedure (p = 0.005). The discriminative accuracy was 0.79 (95% confidence interval 0.77-0.83). CONCLUSIONS: A nomogram was developed that predicts the risk of infection by ESBL-producing Enterobacteriaceae with reasonable accuracy. It could improve clinical decision making and enable more efficient empirical treatment.

RESUMO

BACKGROUND AND OBJECTIVES: Two-port laparoscopic radical cystectomy (LRC) using a multichannel platform through the umbilicus and one additional 10-mm in the right iliac fossa has been recently described. We compare the perioperative and early results of this technique with a cohort of patients simultaneously treated in our institution with four-port LRC and a 7 to 10 cm midline incision. MATERIALS AND METHODS: A matched-pair study comparing perioperative outcomes, postoperative visual analog pain scale (VAPS), and morbidity of two-port (n=30) and four-port (n=30) LRC. Preoperative and perioperative data analyzed and compared included demographics, type of urinary diversion, operative time, blood loss, transfusion requirements, decrease in serum hemoglobin, operative complications, analgesic needs, length of stay, number of nodes removed, and other pathologic information. Complications in the first 3 months were evaluated according to the Clavien-Dindo classification. RESULTS: There was no significant difference between the two groups regarding patient age, gender, body-mass index, American Society of Anesthesiologists (ASA) score, Charlson comorbidity index, tumor stage, percent of positive nodes, positive margin rate, number of nodes retrieved, proportion of neobladders, secondary carcinoma in situ, incidental prostate cancer, or need of systemic chemotherapy. Median operative time was 20 minutes higher in the two-port procedure, but this difference was not statistically significant (p=0.2). Estimated blood loss and differential hemoglobin change were lower in the two-port technique (each p=0.03), but no difference was detected regarding the intraoperative or postoperative transfusion rate. Length of hospital stay was also equivalent. Differences were not observed either in the number or severity of complications. VAPS at days 2, 3, and 5 was significantly lower for two-port LRC (p<0.01). CONCLUSIONS: Two-port LRC performed through an umbilical platform and an accessory 10-mm port seems technically equivalent to standard four-port LRC. Perioperative outcomes regarding hospital stay and complications are tantamount. Diminished blood loss and, especially, less postoperative pain favor the reduced-port approach in this complex urologic minimally invasive procedure.
