Work safety interaction assessment of VOC’s emission under emergency work of IPPC installation

The study evaluated the impact of emissions (VOCs) as a result of the operation of the printing of plant at working positions of those performing their tasks outdoors or in buildings next door. The first part of the paper presents the general characteristics of the process and materials used for printing. The further part shows the results of the modelling of emissions, depending on the operating state of purification (emission in normal conditions and emission in failure state of the afterburner)

Environmental interaction assessment of VOC’s emission from printing plant hot rotary heat-set

The paper presents an analysis of gaseous emissions arising from the operations of printing using a printing process hot offset rotary. The first part presents the general characteristics of the process and the paint used. The following part shows the results of modelling the emission of pollutants according to the efficiency of the cleaning system, as well as depending on other parameters influencing the dispersion process impurities

Iatrogenic Injury of Biliary Tree—Single-Centre Experience

Cholecystolithiasis is among the most prevalent gastrointestinal disorders requiring surgical intervention, and iatrogenic damage to the bile tree is a severe complication. We aimed to present the frequency of bile duct injuries and how our facility handles these complications. We retrospectively analyzed bile duct injuries in patients undergoing surgery. We concentrated on factors such as sex, age, indications for surgery, type of surgery, primary procedure, bile tree injury, repair, and timing as well as early and late complications. There were 22 cases of bile duct injury in the studied material, primarily affecting women—15 individuals (68.2%). Eleven cases (45.7%) of acute cholecystitis were the primary reason for surgery, and an injury to the common bile duct that extended up to 2 cm from the common hepatic duct was the most common complication (European Association for Endoscopic Surgery grade 2). Roux-en-Y hepaticojejunostomy was the most common repair procedure in 14 cases (63.6%). Eleven patients (50%) experienced early complications following reconstruction surgery, whereas five patients (22.7%) experienced late complications. An annual mortality rate of 22.7% (five patients) was observed. Iatrogenic bile duct injury is a severe complication of surgical treatment for cholecystolithiasis. Reconstruction procedures are characterized by high complication rates and high mortality

Glutathione S-Transferase P1 Genetic Variant’s Influence on the HbA1c Level in Type Two Diabetic Patients

GST (glutathione S-transferases) are capable of influencing glucose homeostasis, probably through regulation of the response to oxidant stress. The aim of our study was to investigate the relationship between GSTP1 gene polymorphism and glycated hemoglobin (HbA1c) levels in type two diabetic (T2D) patients. A total of 307 T2D patients were included. Analysis of the GSTP1 gene polymorphism (rs1695) was conducted using the TaqMan qPCR method endpoint genotyping. HbA1c was determined using a COBAS 6000 autoanalyzer. A univariable linear regression and multivariable linear regression model were used to investigate the association between mean HbA1c level and GSTP1 gene polymorphism, age at T2D diagnosis, T2D duration, therapy with insulin, gender, BMI, smoking status. GSTP1 Val/Val genotype, age at T2D diagnosis, T2D duration and therapy with insulin were statistically significant contributors to HbA1c levels (p p = 0.024). The results suggest that GSTP polymorphism may be one of the risk factors for higher HbA1c in T2D patients. Our study is limited by the relatively small sample size, cross-sectional design, and lack of inclusion of other oxidative stress-related genetic variants

NOS2 Polymorphism in Aspect of Left and Right-Sided Colorectal Cancer

Background: The NOS2 gene polymorphism rs2297518 is associated with an increased level of NO, which could contribute to colorectal cancer (CRC) development. We hypothesized that the potential influence of the NOS2 gene polymorphism on cancer development may vary between right-sided and left-sided colon cancers, and rectal cancers. The aim of this study was to determine the rs2297518 polymorphism influence on colorectal cancer development with regard to tumor localization. Methods: This case–control study included 199 patients with CRC and 120 controls. The qPCR endpoint genotyping was conducted using the TaqMan® genotyping assay. Results: This study revealed significant differences in tumor characteristic and in the minor alelle A frequency in the NOS2 genotype between colorectal cancers with different localizations. The mucinous adenocarcinoma was diagnosed significantly more often in right-sided cancers than in left-sided (30.6% vs. 10.9%, p = 0.009) and rectal cancers (30.6% vs. 7.1%, p = 0.0003). The minor allele A of the NOS2 genotype was observed more frequently in right-sided cancers than in left-sided cancers (44.9% vs. 23.1%, p = 0.0137) and more frequently in rectal cancers than in left-sided cancers (40.0% vs. 23.1%, p = 0.0285). Conclusions: In conclusion, the results support the hypothesis that the SNP rs2297518 of the NOS2 gene influences colorectal cancer development with regard to tumor localization
