Introduction Male circumcision is recognized as the most effective method of phimosis treatment. Analyzing the literature, the information about the influence of male circumcision due to phimosis for patients' subjective symptoms such as itching, burning, penile pain, pain during intercourse, and quality of sexual life is insufficient. Aim To investigate the effect of male circumcision due to phimosis to patients' subjective symptoms, including erectile function and satisfaction with their genitals. Methods The single-center prospective study began in January 2018 and ended in January 2020. Sixty-nine male, adult patients, who were qualified for circumcision due to phimosis, were included in the study. Main Outcomes Measures The study outcomes were obtained using questionnaires such as visual analog scale 0-10 for itching, burning, penile pain, and penile pain during intercourse; International Index of Erectile Function (IIEF-5) and Male Genital Self Image Scale 7 (MGSIS-7) to assess the changes in patients sexual functioning. Results Before the circumcision of the 69 patients included in the study, 59 patients (86%) reported some subjective symptoms of phimosis. The most frequent and most severe complaint was pain during intercourse, then itching and burning of the penis. Penile pain at rest was the least frequent. After 3 months from circumcision, subjective symptoms almost completely disappeared. All of 69 patients declared to have a sexual partner. 3 months after circumcision, all patients achieved significant improvement in both obtaining and maintaining an erection based on IIEF-5 score. Their sexual intercourse was more satisfying for them. All patients suffering from phimosis were embarrassed about their genitals before surgery. 3 months after circumcision, satisfaction with genital self-image increased significantly. Conclusion Male circumcision due to phimosis is not only relieving the clinical symptoms of phimosis, but it also improves the quality of sexual life. Czajkowski M, Czajkowska K, Zarańska K, et al.

The increasing prevalence of cardiovascular disease and concomitant chronic kidney disease among the aging populations is responsible for considerable growth of mortality. Additionally, frequent, prolonged hospitalizations and long-term treatment generates progressive decline in bodily functions as well as substantial public health and economic burden. Accessibility to easy, non-invasive prognostic markers able to detect patients at risk of cardiovascular events may improve effective therapy and mitigate disease progression. Moreover, an early diagnosis allows time for implementation of prophylactic and educational programs that may result in decreased morbidity, improved quality of life and reduced public health expenditure. One of the promising candidates for a novel cardiovascular biomarker is mid-regional proadrenomedullin, a derivative of adrenomedullin. Adrenomedullin is a peptide hormone known for its vasodilatory, antioxidant, antiapoptotic and antifibrotic effects. A remarkable advantage of mid-regional proadrenomedullin is its longer half-life which is a prerequisite for plasma measurements. These review aims to discuss the importance of mid-regional proadrenomedullin with reference to its usefulness as a biomarker of increased cardiovascular risk and kidney disease progression.

Maternal aging affects various aspects of oocytes’ physiology, including the functionality of their nuclear apparatus and mitochondria. In the present paper, we wished to investigate whether advanced reproductive age impacts also oocytes’ ability to generate proper Ca2+ oscillations in response to monospermic fertilization. We examined three different mouse strains/crosses: inbred C57BL/6Tar, outbred Tar:SWISS, and hybrid F1 (C57BL/6Tar x CBA/Tar). The females were either 2–4 months old (young) or 13–16 months old (aged). We observed that Ca2+ oscillatory pattern is altered in a strain-dependent manner and that changes were more profound in aged C57BL/6Tar and F1 than in aged Tar:SWISS oocytes. We also showed that maternal aging differently affects the size of Ca2+ store and expression of Itpr, Atp2a2, Txndc4 and Pdia3 genes involved in Ca2+ homeostasis in oocytes of C57BL/6Tar, Tar:SWISS and F1 genetic background, which may explain partially the differences in the extent of age-dependent changes in the Ca2+ oscillations in those oocytes. Maternal aging did not have any visible impact on the distribution of the ER cisterns in oocytes of all three genetic types. Finally, we showed that maternal aging alters the timing of the first embryonic interphase onset and that this timing correlates in C57BL/6Tar and Tar:SWISS oocytes with the frequency of fertilization-induced Ca2+ oscillations. Our results indicate that extreme caution is required when conclusions about oocyte/embryo physiological response to aging are made and complement an increasing amount of evidence that mammalian (including human) susceptibility to aging differs greatly depending on the genetic background of the individual.

Background Sirtuin 1 is involved in the pathogenesis of age-related diseases. Purpose The aim of the study was to assess the clinical and diagnostic value of serum sirtuin 1 concentration in patients with CKD. Patients and Methods The serum sirtuin 1 level was evaluated using ELISA kit in 100 CKD patients stratified for five stages and in a control group of 24 healthy volunteers. Results Serum sirtuin 1 concentration was higher in the CKD group compared with the control group (p<0.05). Sirtuin 1 correlated with conventional CKD biomarkers and eGFR equations, intact parathyroid hormone (iPTH) and age (all p<0.05). Statins, AT 1 receptor antagonists and β-blockers use were associated with decreased sirtuin concentration (p<0.05). Sirtuin 1 was able to distinguish CKD from control group with high sensitivity and specificity (93% and 87%, respectively; AUC=0.954). Surprisingly, after adjustment only iPTH concentration was an independent predictor of sirtuin 1 level. Conclusion The association between sirtuin 1, eGFR equations and iPTH indicates its possible usefulness as a kidney function marker. In terms of iPTH being the only independent predictor of circulating sirtuin 1 it can be considered as an indirect cardiovascular risk biomarker regardless of renal function and provide additional information for patient management. Alternatively, sirtuin 1 is recognized as protective against vascular disease, and we demonstrated a positive correlation with iPTH, which may be related to accumulation of (7-84)-PTH having opposite biological effects to full-length PTH. Further studies are needed to explore the interplay between sirtuin 1, PTH and CKD-related vascular calcification as well as to assess its prognostic value in observational studies.

Purpose To assess the expression of selected cytokines in penile lichen sclerosus (PLS) and associate them with the occurrence of micro-incontinence (MI) in different stages of PLS. Methods The skin biopsies from 49 PLS affected, and 13 from nonlesional foreskins (healthy control adult males undergoing circumcision due to phimosis caused by short frenulum) were obtained. All specimens were used for RNA extraction and RT-qPCR. Quantitative assessment of the gene expression of interleukin 1-A (IL-1A), interleukin 1-B (IL-1B), interleukin 1 receptor antagonist (IL-1RN), interleukin 6 (IL-6), transforming growth factor β1 (TGF-β1), and interferon-gamma (INF-γ) was performed. To determinate the presence of MI, the patients were asked about voiding patterns, especially leaking tiny drops of urine from the urethral meatus after urination. Results IL-1A, IL-6, and INF-γ mRNA levels were approximately 150, 16, and 59 times higher in PLS than in control samples, respectively. The highest IL-1A mRNA levels were observed in early PLS (n = 13), INF-γ in moderate PLS (n = 32), while IL-6 in severe PLS (n = 4). MI was noted in 45 PLS patients vs. 0 in control (p < 0.0001). IL-1A and IL-6 vs control ratios were concentration (ca.) 400 and 30 times higher, respectively, in MI PLS samples than in PLS without MI. Conclusion Occlusion and irritating urine effect are associated with the clinical progression of penile LS with increased mRNA expression of IL-1A, INF-γ, and IL-6 pro-inflammatory cytokines in the foreskin.

Background Mycosis fungoides (MF) skin lesions are characterized by low-grade inflammation, which may be sustained by proinflammatory cytokines as probably interleukin-33 (IL-33). We compared serum concentrations of IL-33 and its receptor ST2 and the frequency of selected IL-33 single nucleotide polymorphisms (SNPs) between patients with MF and healthy controls.Methods In 88 patients with MF and 66 healthy controls, we analyzed SNPs in the 9894 and 11877 loci of the IL-33 gene. Moreover, we measured serum concentrations of IL-33 and its receptor ST2.Results There were no statistically significant differences in the frequencies of both IL-33 SNPs between patients and controls. Compared with controls, patients with MF had similar IL-33 serum concentrations (P = 0.71) but significantly increased ST2 concentrations (P < 0.001). Patients in MF-IA stage had significantly lower ST2 serum concentrations than those with the remaining MF stages (P = 0.002). The studied variables were not related to pruritus severity. Patients with the C(+) IL-33 11877 SNP had lower ST2 serum concentrations than patients with the C(À) 11877 SNP (P = 0.043).Conclusions It was published before that the knockout of the ST2 gene after injection of IL-33 is associated with a reduced inflammatory reaction in the skin, as well as that IL-33 plays a role in allergic and neoplastic disorders. Concerning the difference in ST2 concentration between control and MF group, and C IL-33 11877 SNP possibly influencing the ST2 concentration, the role of IL-33/ST2 signaling, needs further studies.
