Opis:
Introduction: 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 measured biomarkers and their influence on patients’ overall survival. Materials and methods: The retrospective analysis of data on 129 patients admitted to our Department due to the diagnosis of pancreatic cancer was carried out. On the day of admission all the patients had their levels of CA19-9, CA125, CEA and CA15-3 measured. The overall survival (OS) was defined as time elapsing from the day of admission to the day of death. The Kaplan- Meier curves were built for all potential factors, Cox regression model was applied to carry out a multivariate analysis. Results: We retrospectively analyzed 129 patients with a mean age of 62 years. As many as 95 of them had an unresectable lesion and 34 underwent curative operation. In total, the analyzed patient group was characterized by a median survival of 7 months and 12 days. Cumulative 1-year, 2-year and 4-year survival rates were 35%, 16% and 15%, respectively. In univariate analysis, factors such as age >= 60, inoperable lesion, CA19-9 >= 200, CA125 >= 20 and Neutrophile to Lymphocyte Ratio (NLR) >= 5 were associated with a lower median OS. In multivariate analysis, three factors, CA19-9 >= 200, CA125 >= 20 and age >= 60, were found to be statistically significant. Indeed, patients possessing all of them noted much poorer outcomes regarding OS factors: 89 days versus 235 days for the other patients (log rank test P = 0.02). Conclusions: Our study fortifies the evidence that preoperative levels of CA19-9 and CA125 have a direct influence on the longterm OS. Interestingly, in our patient group, the correlation of biomarkers with OS was higher than that of resectability. However, our study has some limitations regarding, for instance, the lack of data on chemotherapy, comorbidities etc. In the view of recent molecular studies on mucin involvement in PC development, it provides a strong clinical evidence to prove their importance.

Opis:
The aim of the study was to assess the expression of MGMT, p16, and APC genes in tumors and matching surgical margin samples from 56 patients with primary OSCC. We also analyzed the association of the clinical variables with the expression of the studied genes. After RNA isolation and cDNA synthesis gene expression levels were assessed by quantitative reverse transcription (qRT)-PCR. Two-sided parametrical Student's t-test for independent groups with equal/unequal variances showed no statistically significant differences in genes' expression in tumor compared to margin samples. No association was found between the genes' expression and clinical parameters, except for MGMT, whose low expression was probably associated with smoking (0.87 vs 1.34, p=0.065). 'Field cancerization' is an area with genetically or epigenetically altered cells and at the same time a risk factor for cancer. Disturbances in gene expression could also be the source of damages leading to cancerization. In conclusion, it is important to mention that the field remaining after a surgery may pose an increased risk of cancer development. It may be suggested that the diagnosis and treatment of cancers should not be concentrated only on the tumor itself, but also on the cancer field effect. Therefore, further molecular analysis on surgical margins and additional research regarding their assessment are required.

Opis:
The Background Delayed graft function (DGF) is a common complication following kidney transplantation and is associated with ischemia-reperfusion injury (IRI). Lymphocytes contribute to the pathogenesis of IRI and ischemia-reperfusion related to delayed graft function. Materials and Methods : 135 Caucasian patients received a kidney graft from deceased heart-beating organ donors. We divided patients into 2 groups - patients with the eGFR>=30 on the 21st day post-transplantation (n=36) and patients with the eGFR<30 on the 21st day post-transplantation (n=99) to assess kidney graft function. We measured serum creatinine levels on 1st and 2nd post-transplant day and preoperative levels of monocytes, lymphocytes, platelets, and neutrophils and their ratios. Results: We have found statistically significant differences between the eGFR<30 and the eGFR>=30 groups in the average lnLymphocytes (0.36 +/-0.6 vs. -0.016 +/-0.74, respectively p=0.004) lnNLR (1,27 +/-0.92 vs. 1.73+/-1.08 p=0.016) lnLMR (1.01 +/-0.57 vs. 0.73 +/-0.64 p=0.02), lnPLR (4.97 +/-0.55 vs. 5.26 +/- 0.67 p=0.023), and CCR 2% (-20.20 +/- 21.55 vs. -4.29 +/- 29.62 p=0.004. In the univariate analysis, factors of lnLymphocytes >=0.22 (OR=0.331 95%CI 0.151-0.728 p=0.006), lnLMR>=1.4 (OR=0.255 95%CI 0.072-0.903 p=0.034) were associated with a worse graft function, while lnNLR>=1.05 (OR=2.653 95%CI 1.158-6,078 p=0.021), lnPLR>=5.15 (OR=2.536 95%CI 1.155-5.566 p=0.02) and CRR2 (OR=3.286 95% CI 1.359-7.944 p=0.008) indicated a better graft function. Conclusion: A higher absolute lymphocyte count (lnLymphocytes) and lnLMR, as well as lower lnNLR and lnPLR were associated with a lower eGFR on the 21st day after kidney transplantation. In the multivariate analysis, CRR2 in combination with either lnLymphocytes, lnNLR or lnPLR improved the accuracy of detecting patients with poor graft function.

Opis:
One of the mechanisms of Candida albicans resistance to azole drugs used in antifungal therapy relies on increased expression and presence of point mutations in the ERG11 gene that encodes sterol 14α demethylase (14DM), an enzyme which is the primary target for the azole class of antifungals. The aim of the study was to analyze nucleotide substitutions in the Candida albicans ERG11 gene of azole-susceptible and azole-resistant clinical isolates. The Candida albicans isolates represented a collection of 122 strains selected from 658 strains isolated from different biological materials. Samples were obtained from hospitalized patients. Fluconazole susceptibility was tested in vitro using a microdilution assay. Candida albicans strains used in this study consisted of two groups: 61 of the isolates were susceptible to azoles and the 61 were resistant to azoles. Four overlapping regions of the ERG11 gene of the isolates of Candida albicans strains were amplified and sequenced. The MSSCP (multitemperature single strand conformation polymorphism) method was performed to select Candida albicans samples presenting genetic differences in the ERG11 gene fragments for subsequent sequence analysis. Based on the sequencing results we managed to detect 19 substitutions of nucleotides in the ERG11 gene fragments. Sequencing revealed 4 different alterations: T495A, A530C, G622A and A945C leading to changes in the corresponding amino acid sequence: D116E, K128T, V159I and E266D. The single nucleotide changes in the ERG11 gene did not affect the sensitivity of Candida albicans strains, whereas multiple nucleotide substitutions in the ERG11 gene fragments indicated a possible relation with the increase in resistance to azole drugs.
