To assess the efficacy and safety of autologous mid-urethral sling (MUS) in women with predominant stress urinary incontinence (SUI).
This prospective cohort study included adult women with predominant SUI seen in our urology clinic between January 2018 and March 2019. Patients with negative cough stress test, history of prior incontinence surgery, urogenital malignancy, pelvic radiation, neurological disease, body mass index more than 40 kg/m
, the presence of more than Stage I pelvic organ prolapse, active urinary tract infection, maximum flow rate less than 15 ml/sec, postvoid residual urine more than 100 ml, abdominal leak point pressure less than 60 cm of H
O, and pregnant women were excluded. Eligible patients underwent a transobturator MUS procedure using rectus fascia as a sling. Before the procedure, patients filled the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptom (ICIQ-FLUTS) and the Female Sexual Function Index (FSFI) questionnaire. Urinary outcomes were assessed at 3- and 12-months while sexual outcomes were assessed at 12-months.
Thirty patients with median age of 44.5 years were included. All patients had a negative cough stress test during follow up. A significant improvement was noted in the ICIQ-FLUTS scale, bother scale, filling and incontinence subscales at 3 and 12 month follow-up. A significant improvement was also noted in the FSFI full scale score and FSFI domains of mean sexual desire, arousal and lubrication at 12 months follow-up. Two patients developed voiding dysfunction requiring urethral dilatation.
Autologous transobturator MUS surgery appears to be safe and efficacious in the short term. More research is needed to clarify its role in the surgical management of SUI in women.

Through solvatochromic analysis of the open-form DASA in conjunction with X-ray diffraction and computational theory, we have analyzed the ionic character of a series of DASAs. First- and third-generation architectures lead to a higher zwitterionic resonance contribution of the open form and a zwitterionic closed form, whereas the second-generation architecture possesses a less charge-separated open form and neutral closed form. This can be correlated with equilibrium control and photoswitching solvent compatibility. As a result of the high contribution of the zwitterionic resonance forms of first- and third-generation DASAs, we were able to control their switching kinetics by means of ion concentration, whereas second-generation DASAs were less affected. Importantly, these results show how the previously reported concentration dependence of DASAs is not universal, and that DASAs with a more hybrid structure in the open form can achieve photoswitching at high concentrations.Creatinine and purines are gout-related metabolites commonly quantified by liquid chromatography coupled with ultraviolet and mass spectrometry. However, the high cost of liquid chromatography coupled with mass spectrometry hindered its extensive use in ordinary hospitals and clinical laboratories. Using the traditional liquid chromatography method, the full separation of these metabolites in complex biological samples is still not achieved. In this study, an improved ultra-high-performance liquid chromatography with ultraviolet spectroscopy method was reported for quantitative determination of five gout-related metabolites (i.e., creatinine, uric acid, hypoxanthine, xanthine, and inosine) in human serum within 10 min. A UHPLC system equipped with a hydrophilic C18 column was used to improve separation, shorten analysis time, and increase analysis throughput. The performance of the method was validated by evaluating linearity (squared correlation coefficient > 0.9991), recovery (92.8-100.0%, with relative standard deviation less then 4.7%), accuracy (relative errors less then 14.6%), precision (0.2-4.1% for intraday and 2.1-7.3% for interday) and stability (-14.1 to 8.3% in autosampler for 12 h and -13.3 to 2.2% for freeze-thaw cycles). This method was successfully applied to quantify gout-related metabolites in serum samples of healthy controls and gout patients, which was expected to be used in the clinical investigation of gout at different stages.
To identify risk factors for urinary retention following AdVance™ Sling placement using preoperative urodynamic studies to evaluate bladder contractility.
A multi-institutional retrospective review of patients who underwent an AdVance Sling for post-prostatectomy stress urinary incontinence from 2007 to 2019 was performed. Acute urinary retention (AUR) was defined as the complete inability to void or elevated post-void residual (PVR) leading to catheter placement or the initiation of intermittent catheterization at the first void trial postoperatively. Bladder contractility was evaluated based on preoperative urodynamics.
Of the 391 patients in this study, 55 (14.1%) experienced AUR, and 6 patients (1.5%) had chronic urinary retention with a median follow-up of 18.1 months. In total, 303 patients (77.5%) underwent preoperative urodynamics, and there was no significant difference between average PdetQmax (26.4 vs. https://www.selleckchem.com/products/dexketoprofen-trometamol.html 27.4 cmH
O), Qmax (16.6 vs. 16.2 ml/s), PVR (19.9 vs. 28.1 ml), bladder contractility indversus longer initial catheterization periods, suggesting that a longer duration of postoperative catheterization may reduce the occurrence of AUR.Host cell proteins (HCPs) are widely regarded as a critical quality attribute for a biotherapeutic product. Bottom up MS is the present gold standard for HCP analysis but suffers from incomplete protein identification due to complex nature of the HCP mixture and limited separation efficiency of the preceding LC-based systems. In this paper, we present for the first time an application involving use of LC-CE-MS/MS platform for analysis of HCPs. It has been demonstrated that the proposed platform has been able to successfully identify 397 HCPs from the supernatants of recombinant Chinese hamster ovary cells, twice and thrice the number of proteins identified by the state-of-the-art LC-MS/MS (189 HCPs) and CE-MS/MS (128 HCPs) analyses, respectively. Of these, 225 HCPs were unique to the LC-CE-MS/MS approach and were not identified by either LC-MS/MS or CE-MS/MS. It is observed that the LC-CE-MS/MS platform combines the benefits of LC-MS/MS and CE-MS/MS techniques and identifies peptides in a wider range of size, pI, and hydrophobicity.
