Here, we aim to evaluate the beneficial effect of dietary supplementation with seven active principles, i.e., lycopene, sulforaphane, silymarin, glutathione, escin, tryptophan, and green tea catechins, on human health. Methods: An extensive search of PubMed and Medline database was performed with the following keywords: “silymarin”, “sulforaphane”, “lycopene”, “green tea catechins”, “tryptophan”, “glutathione” and “escin” accompanied by the keywords “supplement”, “supplementation”, and “nutraceutics”. All preclinical and clinical trials were considered for this review. Results: One hundred and eighteen full-text articles were eligible for inclusion in this review. The papers examined presented considerable variability due to the wide heterogeneity of dosages administered, population involved, and outcomes pursued. Conclusion: Nutritional supplementation with lycopene, sulforaphane, silymarin, glutathione, escin, tryptophan, and green tea catechins appears to exert a wide range of benefits on human health, ranging from mood and cognition to cardiovascular health, fertility, metabolism, antioxidant, and anti-inflammatory capabilities, as well as potential anticancer effects. Further studies are required to better define the potential synergic effect, optimal dosage, mechanism of action, and tolerability profiles of these substances.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":"175 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88157639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the efficacy and safety of a natural supplement, composed of Serenoa repens, Solanum lycopersicum, lycopene, and bromelain, in managing symptoms of this condition among a substantial patient group. Methods: In this prospective study, 245 patients diagnosed with Chronic Prostatitis/Chronic Pelvic Pain syndrome NIH-class III were treated with the aforementioned supplement, alongside lifestyle alterations, such as refraining from spicy foods, alcohol, caffeine, and cycling, for a duration of three months. Patients’ progress was assessed at one and three months using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), the International Prostate Symptom Index (IPSS), quality of life (QoL) scores, and changes in total prostate-specific antigen (PSA) levels. Results: The supplement was well received with no serious adverse events reported. Significant improvements were observed in NIH-CPSI scores, IPSS, QoL scores, and a substantial decrease in total PSA levels at three months compared to baseline, with a positive trend noted from one-month to three-month evaluations. This was consistent in either patients with predominantly voiding or storage urinary symptoms. Conclusions: Our results suggest that this natural supplement in conjunction with lifestyle changes could offer a safe and effective alternative treatment for patients suffering from Chronic Prostatitis/Chronic Pelvic Pain syndrome NIH-class III. However, these findings require validation through further large-scale randomized controlled trials.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":"15 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84893418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Deceased Transplant Recipients: A Forgotten Source of Organ Donors","authors":"D. Nghiem","doi":"10.3390/uro3030020","DOIUrl":"https://doi.org/10.3390/uro3030020","url":null,"abstract":"Background: Organ transplantation is the most successful therapy for end-stage organ disease since it increases the quality of life and life expectancy. For these reasons, over 107,000 patients were on the waitlist in the United States for a transplant in 2022. Unfortunately, only 42,887 transplants were performed, and annually, over 7000 patients on the kidney list die or are too sick to transplant. To solve this severe organ shortage, the use of the deceased transplant recipients with functioning organs, whether transplanted or native, is explored as a new source of organ donors. Methods: To assess the feasibility of this option, first, we will review the rate of kidney transplant recipients dying with functioning grafts (DWGF), their re-use, the organ allocation system, the technical aspects of the organ procurement, and the transplantation of the DWGF kidneys. Then, we will consider the larger group of all deceased transplant recipients as potential donors for all functioning, native, or transplanted organs. Conclusions: (1). All functioning kidney transplants explanted from the deceased transplant recipients have excellent long-term function after re-transplantation. (2). The other functioning organs constitute a large unrecognized pool of transplantable organs. (3). The intensivists and the transplant community should be educated about these new options to improve the organ shortage.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":"45 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81445385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the rapid emergence of FQ-resistant Escherichia coli due to overuse and misuse have resulted in an increase in post-biopsy infections. We requested 723 patients undergoing transrectal or transrectal plus transperineal targeted prostate biopsy to provide preprocedure rectal swabs. The rectal swabs were plated onto deoxycholate hydrogen sulfate lactose agar culture and FQ resistance tests were conducted using the disc diffusion method following the guidelines of the Clinical and Laboratory Standards Institute. All patients undergoing biopsy were given a 1.0 g intravenous injection of cefmetazole (CMZ) 30 min before and 12 h after biopsy. Patients with FQ-resistant organisms received an additional 1.0 g intravenous injection of CMZ every 12 h for an additional 1.5 days, while those without FQ-resistant organisms received levofloxacin 500 mg for 4 days. We evaluated infectious symptoms during the 30 days after the biopsy. We also evaluated the incidence of acute prostatitis within 7 days after the biopsy and isolation rates of FQ-resistant strains. A total of 289 patients (40%) had FQ-resistant isolates on rectal swabs. The overall infectious complication rate was 0.69%. Two patients with FQ-resistant isolates and three patients without them experienced infectious episodes. One patient with FQ-resistant isolates and two patients without them suffered acute prostatitis. The difference in the rates of infectious complication and acute prostatitis rates between FQ-resistant and FQ-susceptible carriers were not significant (p = 1.0 and 1.0, respectively). Post-biopsy sepsis was identified in one patient (0.14%) who had FQ-resistant Escherichia coli. Targeted antimicrobial prophylaxis with cefmetazole based on presence of FQ-resistant isolates on rectal swabs may prevent post-prostate biopsy infectious complications, especially in geographic lesions with a high incidence of FQ-resistant strains in rectal flora.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88765411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preclinical studies have demonstrated the potential benefits of hyaluronic acid in treating Peyronie’s disease, including antifibrotic, anti-inflammatory, and proangiogenic effects, although more research is needed to fully understand its mechanisms of action. Clinical studies have shown promising results, with hyaluronic acid injections leading to improvements in plaque size, penile curvature, and erectile function, and being well tolerated by patients. The findings suggest that HA injections could be a viable and safe treatment option for Peyronie’s disease, particularly in the early stages of the disease. However, more research is needed to determine the optimal dosage and treatment duration for HA injections, and to confirm its efficacy in the stable phase of Peyronie’s disease. Overall, hyaluronic acid is a potentially effective therapy for Peyronie’s disease, with the ability to inhibit fibrosis and promote angiogenesis, and low risk of adverse effects, making it an attractive option for patients who are unable or unwilling to undergo surgery.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":"7 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84683814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
