External quality assessment (EQA) with commutable samples is used for assessing agreement of results for patients' samples. We investigated the feasibility to aggregate results from four different EQA schemes to determine the bias between different measurement procedures and a reference target value.

We aggregated EQA results for creatinine from programs that used commutable EQA material by calculating the relative difference between individual participant results and the reference target value for each sample. The means and standard errors of the means were calculated for the relative differences. Results were partitioned by methods, manufacturers and instrument platforms to evaluate the biases for the measurement procedures.

Data aggregated for enzymatic methods had biases that varied from-8.2 to 3.8% among seven instrument platforms for creatinine at normal concentrations (61-85μmol/L). https://www.selleckchem.com/products/cabotegravir-gsk744-gsk1265744.html EQA schemes differed in the evidence provided about the commutability of their samples, and in the amount of detailipants are needed to improve the ability to aggregate the results for optimal assessment of performance of measurement procedures. Aggregating data from a larger number of EQA schemes is feasible to assess trueness on a global scale.<b>Introduction </b>Pressure ulcers and their consequences can occur in any patient regardless of the underlying disease, so the knowledge of their prevention and treatment is extremely important. <br><b>The aim of the study</b> The aim of the study was to analyze the state of students' knowledge on pressure ulcers.<br><b> Material and methods</b> The research was carried out in the Pomeranian Medical University in Szczecin among students of nursing. The study involved 203 full-time students. Data was collected using a questionnaire consisting of 27 questions. The questions addressed the issues of the formation, prevention and treatment of pressure ulcers. The Kolmogorow-Smirnow, Fisher-Snedecor test, (ANOVA) with Spearman's correlation and Student's t-test were applied for statistical analysis. The statistical significance was assumed to be p ≤ 0.05. <br><b>Results</b> Over half of the respondents (57.64%) had a sufficient level of knowledge on pressure ulcers prevention and treatment. The level increased with the duration of the study, the highest was in the last few years, both I and II cycle of studies. The better (the higher) subjects assessed their knowledge about prevention and treatment of pressure ulcers, they were characterized by a higher level of knowledge. <br><b>Conclusions</b> The knowledge of nursing students on pressure ulcers increases with subsequent years of study. The selfassessment of students' knowledge about pressure ulcers, their prevention and treatment is accurate. Students of the consecutive years are better prepared to carry out anti-bedsore prevention. Students are aware of the need to have knowledge, as well as practice in the field of prevention and treatment of pressure ulcers.<b>Introduction</b> Surgical site infections (SSI) involve 2-11% of all surgical procedures. <br><b>Paper assumption</b> The use of 6% gel with chlorhexidine as an element of preoperative skin preparation of the operated area reduces the number of surgical site infections. <br><b>Aim</b> The aim of the study was to assess the impact of body mass index (BMI), neutrophil to lymphocyte ratio (NLR), total protein, glucose, length of hospitalization before surgery, duration of surgery, length of drainage maintenance, transfusion of red blood concentrate on the number of SSI. <br><b>Materials and methods</b> 248 patients were subjected to prospective analysis. Patients were operated at the Department of General and Oncological Surgery of the Provincial Specialist Hospital in Zgierz. Patients were divided into three groups depending on the microbiological degree of cleanliness of the postoperative wound Group I - clean wounds, Group II - cleancontaminld reduces the risk of surgical site infections, especially in clean-contaminated and contaminated wounds.
The number of patients with end-stage renal failure (ESRF) that require inclusion in the renal replacement therapy program (RRT) is steadily increasing. This fact caused an increase in vascular operations involving the production of vascular access. According to the current guidelines, the best and safest option for a patient with chronic kidney disease (CKD) is the early creation of arteriovenous fistula (AVF). An efficient vascular access to haemodialysis determines the procedure and directly affects the quality of life of a patient with CKD.

The aim of this paper is to present the author's project of the health policy program "Vascular access in renal replacement therapy - fistula first/catheter last", the essence of which is to assess the practical effectiveness and develop an optimal model of CKD patient care organization qualified for the chronic RRT program.

The target population of the program consists of all patients diagnosed with CKD, qualified for the RRT program. The basic measures of the palth policy programme "Vascular access in renal replacement therapy - fistula first/catheter last" covering health care services provided in the scope and on the conditions specified in the regulations issued on the basis of article 31d of the Act of 27 August 2004 on health care benefits financed from public funds, is to check whether planned changes in the organization and delivery of services will improve the situation of patients with CKD eligible for chronic RRT and whether it will be effective the point of view of the health care system.Parathyroid hyperactivity is the state of over-production and PTH secretion [1]. The most common cause of primary hyperparathyroidism is parathyriod adenoma - about 80% of cases, the remaining are parathyroid hyperplasia around 15%cases [2] [3], and in 1-5% of cases, cancer [2] [3] [4] [5]. The disease is diagnosed inabout 40 people in 100,000 [5] [6] [3] [7]. The most common cause of adenoma is the mutation in gene MEN 1. Less than 5% of cases are chronichyperparathyroidism, which is a component of the MEN 1 MEN 2a endocrine adenocarcinoma syndrome [1]. Excess PTH in the body leads to increased mobilization of calcium from the bones, and henceincreased osteolysis, what also increases the absorption of calcium from thedigestive system, as well as an increased amount of phosphate excretion in the urine. Clinical picture of the disease is multiform and often runs in a latent form. Most often the diseaseoccurs in the form of osteoporosis, chronic recurrent kidney stones, and is also commonpyelonephritis on the basis of urolithiasis. The disease may be accompanied by dysphagia, abdominal pain, metallic taste in the mouth, persistent constipation. In addition, from the systemnervous dizziness and headaches, disturbances of consciousness. Arrhythmia the form of additional contractions and paroxysmal tachycardia. Osteolysis, osteoporosis and pathological fractures [1]. The purpose of this article is to bring closer to the reader case of 33 years old woman with primary hyperparathyroidism on the adenoma.<b> Background</b> Colorectal cancer (CRC) is one of the most common malignancies in the world. The cancer stem cell (CSC) markers are associated with aggressive cancer types and poor prognosis. The objective of the study was to evaluate the CD133 expression and to correlate it with clinicopathological features in patients with CRC. <br><b>Material and Methods</b> Our study included ninety patients with CRC who underwent curative surgical resection from 2012 to 2017 at the University Clinic for Digestive Surgery, Skopje, North Macedonia. Tumor samples were first analyzed with standard histopathological methods and then the CD133 expression was investigated immunohistochemically. The level of expression of CD133 was classified semiquantitatively. Low positivity was defined as positive immunoreactivity in <50% of tumor glands, and high positivity was defined as positive immunoreactivity in ≥50% of tumor glands. Furthermore, clinicopathological features of patients were retrospectively reviewed. <br><b>Results</b> High expression of CD133 was found in 47.8% of patients' CRC samples. In 69.6% of patients with metastatic lesions in visceral organs we found high expression of CD133. We found statistically significant differences in the expression of CD133 between patients with and without visceral metastatic lesions (P = 0.0153), between patients with a different T category (P = 0.0119), N status (P = 0.0066) and grade (G) (P = 0.0115). Our results showed that the stage of disease has the greatest impact on expression of CD133 (P < 0.00001). <br><b>Conclusion</b> High expression of CD133 is a useful marker for prediction of the clinically aggressive type of CRC and can be routinely implemented in standard pathohistological diagnostics.<b>Introduction </b>Pancreatic cancer is a devastating disease, being the seventh cause of cancer-related deaths worldwide. Its aggressiveness is due to its specific biology and the late diagnosis of cancer. Therefore, the prognosis for patients suffering from this cancer is dismal, with 5-year overall survival rate of around 6-10%. Up to date, only a complete surgical resection of the cancerous entity warrants a significant improvement in patients' survival. Nevertheless, the pancreatic cancer's biology is still not fully elucidated, so that the accuracy of prognosis for certain patients is highly uncertain. Consequently, the importance of both clinical and basic research aiming to reveal the crucial molecular factors affecting long-term prognosis should be highlighted. There is a growing number of evidence that biomarkers of PC not only reflect the presence of tumor itself but also present a "hint" regarding its physiology. Thus the aim of this study was to assess the levels of commonly measuredomorbidities etc. In the view of recent molecular studies on mucin involvement in PC development, it provides a strong clinical evidence to prove their importance.Incisional ventral hernia occurs after almost every fourth laparotomy. Still, both simple suturing of the hernia defect and open mesh repair, lead to a high incidence of infections and recurrences. In recent years, we have observed a further evolution of operational techniques used in order to reduce the number of complications. The search for effective repair methods is currently going in two directions on the one hand, techniques to reduce tissue tension in the suture line are being developed and disseminated (including modifications to the so-called Ramirez technique); on the other hand, minimally invasive techniques are introduced that allow placement of large synthetic meshes without the need for extensive tissue dissection using open repair. In the first group of presented techniques, emphasis is put on basics and access in the following repair method original Ramirez technique, modified Ramirez technique, anterior component separation with periumbilical perforator-sparing, endoscopic anterior component separation and transversus abdominis release.
