Background: To compare four automated immunoassays for the measurement of 25(OH)-vitamin D (25-OHD) and to assess the impact on the results obtained from a healthy population. Methods: We analysed 100 serum samples on Unicel DxI 800 (Beckman Coulter), Architect i1000 (Abbott), Cobas e411 (Roche) and Liaison XL (DiaSorin). Passing-Bablok regression and Bland-Altman plots were used for method comparison. In order to categorise the obtained values, results were categorised into the following groups: 0-25 nmol/L, 25-50 nmol/L, 50-75 nmol/L and above 75 nmol/L and compared. The percentage of samples below 75 nmol/L, and below 50 nmol/L was then calculated for every method. Results: According to paired comparisons, each method differs from others (p<0.0001) except Cobas vs Architect, which do not show a statistically significant difference (p=0.39). The strongest correlation was found between Liaison and Architect (ρ=0.94, p<0.0001). The percentage of samples below the recommended value of 75 nmol/L were: 70% (Architect), 92% (Liaison), 71% (Cobas) and 89% (Unicel). The percentage of samples below the value of 50 nmol/L were: 17% (Architect), 55% (Liaison), 28% (Cobas) and 47% (Unicel). Conclusions: The observed differences stem from the use of different analytical systems for 25-OHD concentration analysis and can result in different outcomes. The recommended values should be established for each assay in accordance with the data provided by the manufacturer or in the laboratory, in accordance with proper standardisation.

Background: It has been shown that decreased expression and activity of extracellular matrix protein mindin correlate with various types of cancers including breast, colon and lung cancers. The aim of the presented study was to investigate the serum mindin levels in prostate cancer. Methods: Mindin concentrations in serum were measured in 56 patients with prostate cancer (mean age 68 years) and in control group of 29 healthy men (mean age 64 years) using commercially available enzymatic immunoassay (Cusabio, WuHan, China). The patients were divided with respect to the severity of the disease into two groups according to the EAU guidelines (stage 1, 2 - less severe tumours, stage 3, 4 - severe tumours). Results: Serum mindin concentrations were significantly elevated in the group of healthy individuals unlike in the patients with prostate cancer (2.12 ng/mL vs 0.78 ng/mL, with P=0.0007, AUC=0.705). Patients with less severe tumours (stage 1, 2) and severe tumours (stage 3, 4) had significantly decreased levels of S-mindin as well (P=0.0037), although the difference in serum mindin concentrations between the patients with less severe and severe tumours was not significant. Conclusions: Concentrations of mindin were decreased in patients with prostate cancer and reduced in patients with less severe prostate cancer as well. Mindin appears to be a promising diagnostic marker useful in the diagnosis of prostate cancer.

BACKGROUND/AIM: Obesity is currently considered to be the most frequent metabolic disease worldwide, not only in developed but also in developing countries. The aim of this work was to describe the development of health status in soldiers of the Armed Forces of the Czech Republic (ACR) and to emphasizethe markers of non-communicable diseases. Our study describes the anthropometric and biochemical parameters of a large group of Czech Army professional soldiers. Data were obtained over a period of 11 years. METHODS: During the monitored period, from 1999 to 2009, military physicians carried out on the average 6,360 examinations on professional soldiers per year and monitored their health and nutritional status with the aim of preventing the risk factors of non-communicable diseases. These examinations are compulsory for all professional soldiers at the age of 25, 30, 33, and 36 years. From the age of 39, these examinations are carried out every year till the end of their career. Besides taking personal histories and carrying out standard physical examinations, blood was taken for biochemical examination. The following anthropometric parameters were monitored: body constitution using body mass index (BMI) and waist circumference. Our study describes only part of the data concerning anthropometric and biochemical parameters of professional soldiers which were obtained over a period of 11 years. RESULTS: Average BMI values in men were in the overweight range (26.5-27 kg/m2). Average values of waist circumference, however, ranged from 91.9 cm to 93.4 cm. Between the first and the last year of monitoring a statistically significant decrease in these values ranging from 93.4 ± 9.8 cm to 92.7 ± 9.5 cm (p < 0.001) was observed. All monitored anthropometric parameters in female professional soldiers were within normal limits. During the monitored period the proportion of overweight men gradually increased from 52% to 57.1% (p < 0.001). There were no statistically significant changes in the prevalence of obesity in men (12-15%). Average glycaemia levels were within normal range in both men and women. A statistically significant decrease in these levels, however, was observed in men (from 5.1 ± 0.9 mmol/L to 4.8 ± 0.7 mmol/L (p < 0.001) and in women (from 4.9 ± 0.6 mmol/L to 4.6 ± 0.6 mmol/L (p < 0.001). Concerning the lipid profile in men, a significant decrease in average values of total cholesterol, triglycerides and LDL cholesterol was observed; from 5.5 ± 1.1 mmol/L to 5.1 ± 1.0 mmol/L (p < 0.001), from 2.0 ± 1.6 mmol/L to 1.6 ± 1.2 mmol/L (p < 0.001) and from 3.4 ± 1.1 mmol/L to 3.2 ± 0.9 mmol/L (p < 0.001), respectively. CONCLUSION: During the monitored period only one-third of military professionals had normal body weight. More favorable situation was in female professional soldiers, two-thirds of them had normal body weight during the monitored period. Additionally, the increase in the number of individuals with BMI values in the overweight range was observed. Although the number of overweight soldiers was overestimated as a result of the inclusion of individuals with increased body weight due to well-developed musculature, the number of overweight and obese soldiers is still high.

INTRODUCTION: Infection with Clostridium difficile (CDI) is the most frequent cause of nosocomial diarrhoeas. Most cases are successfully treated by antibiotic therapy, but nearly 10% may progress to the fulminative form of this condition. The objective of the work is retrospective evaluation of the results of surgical treatment in patients with the fulminative form of Clostridium colitis with revealing of risk factors leading to serious post-operative morbidity and mortality. PATIENTS AND METHODOLOGY: Retrospective evaluation of the results of surgical treatment in patients with the fulminative form of Clostridium colitis between 2008 and 4/2012. RESULTS: Between 2008 and 4/2012 Clostridium toxins were positively detected in 1,088 patients in total, 21 of whom underwent operations due to the fulminative form of Clostridium colitis. The operations included 4 total colectomies with terminal ileostomy, 15 subtotal colectomies with terminal ileostomy, 1 caecostomy and 1 axial ileostomy. The 30-day mortality was 23.8%, and morbidity reached 66.6%. High leukocytosis is a statistically significant predictor of post-operative mortality and morbidity (p = 0.008). CONCLUSION: Early indication for a colectomy operation with terminal ileostomy in patients with the fulminative form of Clostridium colitis leads to lower morbidity and mortality.
