ABSTRACT Purpose This study examined and compared efficacy, safety, satisfaction, and complications of the retropubic Safyre™ sling and a retropubic hand-made synthetic sling (HMS) in a short-, mid- and long-term follow-up. Methods We retrospectively reviewed a prospectively maintained database of women who underwent Safyre™ or HMS between March 7ths 2005 and December 27ths, 2017. Patients had first assessment (7-10 days), second (40-45 days), and third (sixth month) postoperatively. Between September and December 2018, patients who completed at least one year of surgery, received a telephone call. Follow-up compared quartiles of follow-up time to determine complications (Clavien-Dindo), success rates (International Consultation on Incontinence Modular Questionnaire for Urinary Incontinence Short Form – ICIQ-UI SF), and patient satisfaction. Results Three hundred fifty-one patients underwent surgery and 221 (63%) were evaluated after a median of 78.47 (± 38.69) months, 125 (55%) in the HMS, and 96 (45%) in the Safyre™ group. Higher intraoperative bladder injury was observed with Safyre™ (0% vs. 4.2%, p=0.034), and a tendency for urinary retention, requiring indwelling urinary catheter over 24 hours (2.4% vs. 8.3%, p=0.061). Both HMS (p<0.001) and Safyre™ (p<0.001) presented improvements on ICIQ-UI SF. There were no differences in satisfaction, subjective cure rates, ICIQ-UI SF, or complications between groups. Conclusions Both HMS and Safyre™ have similar satisfaction and subjective cure rates, with marked ICIQ-UI SF score improvement. Higher rates of intraoperative bladder injury were seen in patients who received Safyre™ retropubic sling.

ABSTRACT Purpose: To establish whether the citrate concentration in the seminal fluid ([CITRATE]) measured by means of high-resolution nuclear magnetic resonance spectroscopy (1HNMRS) is superior to the serum prostate-specific antigen (PSA) concentration in detecting of clinically significant prostate cancer (csPCa) in men with persistently elevated PSA. Materials and Methods: The group of patients consisted of 31 consecutively seen men with histological diagnosis of clinically localized csPCa. The control group consisted of 28 men under long-term follow-up (mean of 8.7 ± 3.0 years) for benign prostate hyperplasia (BPH), with persistently elevated PSA (above 4 ng/mL) and several prostate biopsies negative for cancer (mean of 2.7 ± 1.3 biopsies per control). Samples of blood and seminal fluid (by masturbation) for measurement of PSA and citrate concentration, respectively, were collected from patients and controls. Citrate concentration in the seminal fluid ([CITRATE]) was determined by means of 1HNMRS. The capacities of PSA and [CITRATE] to predict csPCa were compared by means of univariate analysis and receiver operating characteristic (ROC) curves. Results: Median [CITRATE] was significantly lower among patients with csPCa compared to controls (3.93 mM/l vs. 15.53 mM/l). There was no significant difference in mean PSA between patients and controls (9.42 ng/mL vs. 8.57 ng/mL). The accuracy of [CITRATE] for detecting csPCa was significantly superior compared to PSA (74.8% vs. 54.8%). Conclusion: Measurement of [CITRATE] by means of 1HNMRS is superior to PSA for early detection of csPCa in men with elevated PSA.

Carboxymethyl-glucan (CM-G) is a soluble derivative from Saccharomyces cerevisiae (1 → 3)(1 → 6)-β-D-glucan. The protective efficiency of CM-G against DNA damage in cells from patients with advanced prostate cancer (PCa), and undergoing Androgen Deprivation Therapy (ADT), was evaluated. DNA damage scores were obtained by the comet assay, both before and after treatment with CM-G. The reduction in DNA damage, ranging from 18% to 87%, with an average of 59%, was not related to the increased number of leukocytes in peripheral blood. The results demonstrate for the first time the protective effect of CM-G against DNA damage in patients with advanced PCa. Among smokers, three presented the highest reduction in DNA damage after treatment with CM-G. There was no observable relationship between DNA damage scores before and after treatment, and age, alcoholism and radiotherapy.
