N-acetylcysteine suppresses aortic stenosis development within a murine product by hindering shear-induced activation associated with platelet hidden TGF-β1.
A review of current literature on the results of surgical treatment of patients with pelvic organ prolapse by vaginal approach is presented in the article. The relevant issues are the safety and efficiency of using mesh implants for the surgical correction of pelvic organ prolapse. Most experts recognize a need for further improvement of vaginal reconstruction techniques using synthetic meshes, however, current restrictions in a number of countries significantly impact on the respective studies. Despite the many scientific works and various publications, to date there is no single concept of the pelvic organ prolapse. It is necessary to conduct multicenter clinical studies in order to further develop clinical guidelines and to determine a place of these operations in the surgical treatment of pelvic organ prolapse.Non-antibacterial methods of prevention and treatment of lower urinary tract infection are described in the article. The current view on the mechanism of treatment effect of D-mannose is presented, which contributes to the prevention of bacterial invasion. Pathogenetic concepts for using D-mannose as specific antiadhesin or a competitive blocker of bacterial invasion is provided. In addition, we discussed the results of basic and clinical studies, proving the efficiency of D-mannose for prevention and treatment of lower urinary tract infection.The review describes large-scale microbiological studies performed in Russia over the past 20 years to study urinary tract infections (UTIs). The article analyzes data on the structure of UTI pathogens, as well as on the antibiotic resistance of the main uropathogens, compares the data with similar foreign studies. From 1999 year, 7 large multicenter microbiological studies were carried out in Russia to obtain the data of the antimicrobial resistance of uropathogens caused community-acquired UTIs. An analysis of the data allows described trends in antimicrobial resistance - high level of resistance of uropathogens to aminopenicillins, co-trimoxazole, fluoroquinolones, an increase antimicrobial resistance to amoxicillin / clavulanate, and third generation cephalosporins. In review discussed a critical assessment of various approaches to the use of data on the sensitivity of uropathogens to antimicrobial drugs when antimicrobial therapy is provided. The necessity of comparing not only microbiological data obtained from different sources, but also clinical data, characteristics of pharmacodynamics and pharmacokinetics of antimicrobial drugs is discussed. The review discusses the difficulties associated with the clinical interpretation of data on the sensitivity of microorganisms, primarily in the limited objective information describing the correlation of in vitro data with the clinical efficacy of therapy. The publication substantiates the need for a wider conduct of not only microbiological, but also clinical studies to obtain data on the comparative efficacy of the used antimicrobial drugs.Approximately 15% of couples of reproductive age are infertile. Among patients with infertility, nearly 10-15% have azoospermia. ACY-1215 molecular weight The current treatment methods of non-obstructive azoospermia, in particular the use of mesenchymal stem cells, and the comparative analysis of the cost-effectiveness of different methods are discussed in the article.Varicocele is the most common and treatable cause of male infertility. Therefore, surgical treatment of varicocele should be recommended for motivated patients and infertile couples who do not have other identified causes of infertility. Varicocelectomy has been proved to improve sperm parameters and improve chances of successful conception in most patients. However, surgical treatment is associated with certain risks, and therefore, the choice of the optimal treatment is under discussion. A total of 78 articles using a search in MEDLINE database (PubMed) were found and included in the review, dedicated to current concepts of functional anatomy of testicular arteries and veins. The current recommendations of professional communities regarding the selection of patients for varicocelectomy are described. The efficiency and safety of various surgical procedures for varicocele is analyzed. This review suggests high inconsistences in the literature. The available information on the indications for surgical treatment, as well as comparative data on the efficiency and safety of the inguinal, laparoscopic and microsurgical sub-inguinal approaches are presented. When urologist faces with a diagnosis of varicocele, individual approach should be applied, with a discussion of both benefits and possible complications of surgical treatment. Of the many existing techniques, microsurgical ligation of dilated veins is the most preferred.A new coronavirus infection caused by SARS-CoV-2 was first identified in December 2019. It has spread quickly and caused a global pandemic. Analysis of demographic factors reveals a disproportionately large number of men with severe forms of the disease. Moreover, mortality rate is also higher in men. The currently available data regarding potential risks to the male reproductive system, including pathophysiological basics, detection of viral RNA in the reproductive tract, risk of orchitis, hypogonadism, possible influence of oxidative stress, etc. are described in the review.Angiomyxoma is a rare benign tumor prone to aggressive and invasive growth and relapse. Very few case reports of tumors with this morphology have been published in the world literature. In this paper, we report a rare case of penile angiomyxoma, which illustrates that any preoperative examination does not allow physicians to suspect this tumor type. This fact makes physicians be alert for cancer and use the active surgical tactics even if a tumor is supposed to be benign.A clinical case of the successful surgical treatment of patient with multiple primary cancers, including locally-advanced right renal cell cancer, transitional-cell cancer bladder cancer and metachronous transitional-cell cancer of the left kidney with one of the longest follow-up and survival time described in the literature.
