Background Testicular cancer (TC), due to its non-specific symptoms and occurrence in young men, is particularly dangerous. A critical point for early diagnosis is awareness of the disease and the willingness to perform a testicular self-examination (TSE). The main aim of the study was to assess the knowledge of 771 adult men about testicular cancer. Additionally, the sources of information on TC and TSE were analyzed and the influence of demographic factors on the willingness to join preventative programs was examined. Materials and methods The study was carried out during the Movember2020 campaign, where a testicular ultrasound was performed on participants. They were asked to complete a questionnaire with 26 questions to assess their knowledge. Results The results obtained in the study indicate a low level of knowledge (average 3.5 points out of 18) about TC. Living in a large city (OR = 1.467; p = 0.03), as well as an earlier conversation about TC (OR = 1.639; p = 0.002), increased the awareness about the disease. Additionally it showed that many participants do not perform TSE at all (52.4%) and that only few perform TSE frequently (18.4%). Relationship status (OR = 2.832; p < 0.001) and previous conversations about TC (OR = 1.546; p = 0.02) was reported to be the main contributing factors in males deciding to have TSE. Conclusions Our research indicates large educational neglect in terms of knowledge about TC and reluctance in performing TSE. It is worth carrying out preventative actions periodically on an increasing scale, not only for the screening of testicular cancer, but also to expand knowledge on this subject.

The increasing number of end-stage heart failure patients eligible for heart transplant and the disproportionately low number of donor hearts have led to increased interest in ventricular assist devices (VAD). These devices can be used as a bridge to decision, bridge to recovery, or bridge to candidacy. The main advantage of mechanical circulatory support (MCS) is the improvement of organ perfusion and function, which leads to better quality of life and survival. The MCS can also be used as a destination therapy in end-stage heart failure patients who are not eligible for heart transplant. It should be remembered that, despite the tangible benefits, VAD implantation may also be associated with the risk of serious complications, such as bleeding, infection, arrhythmias, blood clots, right ventricular failure, and cardiovascular events. This study presents an up-to-date overview of the current knowledge on the role of MCS in modern medicine.

Introduction Renal cell carcinoma is a highly aggressive malignancy that causes significant morbidity and mortality. The rising number of newly diagnosed renal tumors results in a great need to search for new preoperative markers to evaluate the course of the disease and to help select patients who would benefit the most from additional postoperative care. The aim of our study was to evaluate the prognostic value of mean platelet volume-to-lymphocyte ratio (MPVLR) in patients undergoing nephrectomy for nonmetastatic clear cell renal cell carcinoma (ccRCC). Materials and methods A total number of 344 patients with proven nonmetastatic ccRCC treated with radical or partial nephrectomy at our institution between January 2003 and December 2012 were included in our analysis. Based on the optimal cutoff value of MPVLR, which was determined by the receiver operating characteristic curve, our study population was divided into two groups, with low and high MPVLR. Differences in overall survival between groups were compared using the Kaplan-Meier method with log-rank testing. The Cox proportional hazards regression model was applied to perform univariate and multivariate analysis. Results Study subjects with high MPVLR were older and had more advanced tumors. Tumor necrosis and higher TNM stages were also more prevalent in this group of patients. Mortality in patients with high MPVLR was significantly higher than in patients with low MPVLR. In the multivariate analysis, after adjustment for pathological and clinical covariates, high MPVLR (≥ 3.61) was independently associated with higher long-term overall mortality in nonmetastatic ccRCC patients. Conclusion MPVLR is an easily obtainable prognostic marker for overall survival in nonmetastatic ccRCC patients treated with nephrectomy.
