Evaluation of sensitivity profiles to fosfomycin in bacterial urine samples from outpatients.

OBJECTIVE: To evaluate and compare the susceptibilities of bacteria found in outpatient cultures to fosfomycin and other main antibiotics commonly available in clinical practice. STUDY DESIGN: A retrospective cross-sectional study was conducted using 2,673 positive urine cultures collected between 2014 and 2017 at private laboratories located in the cities of Niterói and São Gonçalo. Susceptibilities to fosfomycin and other antibiotics were tested using the McNemar test with the level of significance set at 5 %. RESULTS: Out of the 2,673 samples tested, 94.1 % were susceptible to fosfomycin. Escherichia coli was responsible for 68.8 % of the positive samples, and susceptibility to fosfomycin was observed in 97.9 % of these cases. Susceptibility to fosfomycin in Klebsiella spp. represented 86.6 % of cases, Enterococcus spp., 94.9 % and Proteus mirabilis, 83.3 %. The highest rate of susceptibility for E. coli was observed with fosfomycin, with the only exception being imipenem (p < 0.001). Klebsiella spp. showed a similar profile, except that there was no difference between susceptibilities to fosfomycin and gentamicin (p = 0.91). Susceptibility of Enterococcus spp. to fosfomycin was like that of nitrofurantoin and ampicillin. Finally, the susceptibility of P. mirabilis to fosfomycin was greater than it was for trimethoprim-sulfamethoxazole and nitrofurantoin. CONCLUSIONS: The microbiological profile established here shows substantial sensitivity to fosfomycin in the urine samples analysed. In most cases, there was a sensitivity profile that was favourable to the use of fosfomycin or at least comparable to the other antibiotics studied.

Predictors for de novo stress urinary incontinence following pelvic reconstructive surgery with mesh.

OBJECTIVE: The aims of this study are to describe the postoperative incidence of de novo stress urinary incontinence (SUI) in women who underwent anterior vaginal compartment prolapse repair using synthetic polypropylene mesh and to identify risk factors for this outcome. STUDY DESIGN: A retrospective cohort study of 146 women who underwent anterior vaginal repair from 2007 to 2017 and followed by a minimum period of 12 months was performed. The incidence of de novo SUI was evaluated at 3 and 12 months of follow-up. Women with concomitant or prior anti-incontinence surgery were not included. Preoperatively, all patients had a negative stress test and no evidence of occult SUI on urodynamics. The outcome was considered positive if the patient had complaints of SUI at the follow-up. Variables associated with the outcome with a p-value ≤ 0.10 were included in a logistic regression model to calculate the relative risk (RR) for de novo SUI. For multivariate analysis, all analyzes were performed considering a significant p-value ≤ 0.05. RESULTS: The incidence of de novo SUI at 3 and 12 months of follow-up was 15.8 % and 20.5 %, respectively. Higher body mass index (BMI), diabetes, anterior vaginal wall prolapse stage ≥ 3, older age at first pregnancy and higher first desire to void during the urodynamic evaluation were positively associated with de novo SUI in the bivariate analysis (p ≤ 0.10). Previous perineoplasty had a negative association with the outcome analyzed, suggesting a protective effect. After the multivariate analysis, higher BMI (RR 1.19, 95 % confidence interval [CI] 1.05-1.36), diabetes (RR 4.18, 95 % CI 1.32-13.21) and anterior vaginal wall prolapse stage ≥ 3 (RR 14.74, 95 % CI 1.64-132.0) remained as risk factors for de novo SUI (p ≤ 0.01). CONCLUSION: The incidence of de novo SUI after the surgical correction of anterior vaginal wall prolapse with synthetic mesh in this population was 15.8 % and 20.5 % at 3 and 12 months of follow-up, respectively. Continent women who underwent this surgical procedure and who had a higher BMI, diabetes and anterior vaginal wall prolapse stage ≥ 3 had a higher risk of presenting de novo SUI.

Autonomic modulation in patients with congenital generalized lipodystrophy (Berardinelli-Seip syndrome).

AIMS: This study was designed to assess cardiac autonomic regulation in congenital generalized lipodystrophy (CGL) patients using 24 h heart rate variability (HRV). METHODS AND RESULTS: A cross-sectional study was carried out to evaluate 18 patients with CGL and 19 healthy controls matched by sex and age. We measured blood pressure, plasma concentrations of glucose, triglycerides, cholesterol, high-density lipoprotein-cholesterol, insulin resistance by the homeostatic model assessment (HOMA-R), left ventricular mass (LVM) (by two-dimensional echocardiography), and 24 h HRV (by the time domain indices MeanRR, SDNN, and rMSSD). Compared with controls, CGL patients had higher blood pressure (systolic, 131.1 vs. 106.3 mmHg, P < 0.05; diastolic, 85.0 vs. 68.2 mmHg, P < 0.05) and 10 patients met criteria for arterial hypertension and concentric left ventricular hypertrophy (LVM index > or =115 g/m(2)and relative left ventricular wall thickness > or =0.42). Patients with CGL had higher levels of glucose, triglycerides, cholesterol, and HOMA-R and 12 met criteria for type 2 diabetes mellitus. Compared with controls, CGL patients had lower MeanRR (639.8 vs. 780.5 ms, P < 0.001), SDNN (79.2 vs. 168.5 ms, P < 0.001), and rMSSD (15.8 vs. 59.6 ms, P < 0.001). In CGL patients, the reduction in HRV was independent of the metabolic and haemodynamic disturbances. CONCLUSION: Congenital generalized lipodystrophy patients have abnormal autonomic modulation, reflected by increased heart rate and pronounced reduction in HRV, independent of the metabolic and haemodynamic disturbances observed in this disorder.

Effects of tamoxifen on Doppler velocimetry parameters of periurethral vessels in postmenopausal women.

The purpose of the present study was to assess the effect of tamoxifen on periurethral vessels by Doppler velocimetry examination. Increase in the number of these vessels as well as decrease in resistance and pulsatility indices by tamoxifen were observed.
