The results of studies of a newly isolated Serratia species K-57 strain are presented. The strain is characterized by antiviral activity towards human influenza A/Aichi/2/68/H3N2, vaccinia, mouse smallpox, and herpes simplex-2 viruses. The detected characteristics of the strain, including the data on activities on nucleolytic enzymes, recommend it for the development of therapeutic and preventive antiviral drugs.We performed a correlation analysis of the morphometric parameters of mesenteric lymph nodes and cytokine content in the lymph of thoracic duct in rats with chemically induced breast cancer. The study showed that activity of the local immune response in the lymph nodes in breast cancer is aimed at antitumor protection. In breast cancer, the area of the paracortical zone remained at the level of the intact group, while the area of lymphoid nodules with germinative centers and the area of medullary substance increased; the number of macrophages in the thymus-dependent zone and zone responsible for humoral immunity also increased. The following positive correlations were revealed in germinative centers and medullary substance, number of mitotic cells correlated with cytokine IL-5 content and the number of medium lymphocytes correlated with the content of chemokine MIP-1α; in the germinative centers, the number of immunoblasts correlated with the level of cytokine GRO/KC, in the paracortical zone, the number of macrophages correlated with the level of chemokine MCP-1, the number of reticular cells correlated with IL-6 and M-CSF content; in medullary substance, the number of small lymphocytes and mature cells plasma cells (their content was reduced) correlated with the level of chemokine GRO/KC, which can be caused by their migration from the lymph node.PURPOSE To investigate the relationships between hematuria, clinicopathological features and renal outcomes in patients with biopsy-proven diabetic nephropathy (DN). METHODS This cohort study included 261 patients with DN. Participants were divided into two groups according to number of red blood cells per high-power field (RBC/hpf) in urine sediment the hematuria (-) group (≤ 3 RBC/hpf) and the hematuria (+) group (> 3 RBC/hpf). Basic clinical parameters were measured at the time of renal biopsy; relationships between hematuria and clinicopathological features and renal outcomes were analyzed. RESULTS Patients in the hematuria (+) group often had overt proteinuria. Interstitial inflammation was more severe in the hematuria (+) group than in the hematuria (-) group. Glomerular arteriolar hyalinosis, interstitial fibrosis and tubular atrophy were comparable between groups. For patients with early DN (eGFR ≥ 60 ml/min/1.73 m2), urinary RBC/hpf at baseline was positively correlated with glomerular classification, interstitial fibrosis/tubular atrophy scores and interstitial inflammation scores. In prognostic analysis, hematuria was associated with a higher risk of progression to end-stage renal disease. Selleck N-Acetyl-DL-methionine Hematuria remained an independent predictor after adjustment for confounding factors such as sex, age, duration of diabetes, serum glucose level, hypertension, cholesterol, eGFR and urine protein excretion, especially in patients with early DN and in male patients. CONCLUSION In this study, hematuria was associated with more severe renal pathologic lesions in patients with DN. The presence of hematuria could be an independent predictor of renal outcome in patients with early DN.BACKGROUND Interventional radiology (IR) is underrepresented in undergraduate medical curricula across Europe. By continuing to challenge the boundaries of IR, a rise in the demand for radiologists has been inevitable - a trend not met by a corresponding rise in the supply of radiologists. On tracing the roots of this shortage, lack of awareness of the specialty within medical trainees coupled with a global lack of IR teaching in undergraduate education seem to constitute major exacerbating factors. The purpose of this study was to identify gaps in the field of IR education and address these by implementing an international IR simulation-based course for undergraduates. RESULTS Implementation of a multi-modality simulation-based course consisted of seven modules incorporating technical and non-technical skills, basic science and applied clinical science modules. Of all participants, 90.7% (N = 68) never had previous IR teaching experience and only 28% (N = 21) had a previous placement in an IR department. Following the course, confidence improvement was statistically significant both in IR skills (1/5, p  less then  0.01) and knowledge (1/5, p  less then  0.01)]. The majority (90.7%) said they would benefit with more exposure to IR. In terms of the students' motivation for a career in IR, 32% (N = 24) reported that they would more likely consider a career in IR after completing the course. CONCLUSION Delivery of a tetra-core simulation course with the aim to address the gaps in undergraduate IR education has had a positive impact on students' skills, confidence levels as well as motivation. We propose reviewing the curricula across medical schools in Europe to identify gaps and address any inadequacies; for this, we consider our simulation course an excellent starting point.We present the first detailed report of acneiform eruptions in patients on CTLA-4 inhibitor therapy. Acneiform eruptions commonly occur (up to 75-100%) as a cutaneous adverse event associated with EGFR inhibition; however, acneiform eruptions have not been highly reported as a cutaneous adverse event associated with CTLA-4 inhibitor therapy. We conducted a retrospective chart review of our institution's database to assess cutaneous adverse events associated with ipilimumab and tremelimumab, identifying 12 patients with acneiform eruptions (2 on tremelimumab and 10 on ipilimumab). The median time to onset of rash was 3 weeks after starting CTLA-4 inhibitor therapy, ranging from 0.7-45 weeks. Median time to cutaneous resolution was 6 weeks, ranging from 2 to 282 weeks. Treatment included oral and topical antibiotics, antihistamines, and oral or topical corticosteroids with four patients receiving no treatment. Acneiform eruptions are seen less commonly with CTLA-4 inhibitors than other cancer therapies, but awareness that it does occur is important for clinical practice.
