is a common etiological factor of hospital infections, which, in extreme cases, can lead to the death of patients. Most strains belonging to this bacterium species synthesize very dangerous toxins: toxin A (TcdA) and B (TcdB) and binary toxin (CDT). The aim of this study was to assess the suitability of agarose gel electrophoresis separation of multiplex PCR amplicons to investigate the toxinogenic potential of strains.

Department of Medical Biology and Biochemistry, Faculty of Medicine, Ludwik Rydygier Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Toruń, 24 Karłowicza St., 85-092 Bydgoszcz, Poland.

Oxidative stress, characterized by an overproduction of reactive oxygen species that overwhelm the body's physiological defense mechanisms, is a key factor in the progression of parasitic diseases in both humans and animals. Scabies, a highly contagious dermatological condition caused by the mite var. , affects millions globally, particularly in developing regions.

became one of the main causes of nosocomial infections in all clinical settings worldwide, especially among patients undergoing antibiotic therapy. The incidence and severity of infections, from mild diarrhea to life-threatening pseudomembranous colitis, correlate with the spread of the hypervirulent binary toxin (CDT)-producing strains. The use of the real-time HRM-PCR method enables the identification of hypervirulent strains directly in the diarrheal stool samples of patients suspected of being infected with this bacterium.

Article Synopsis
  • The rising incidence of colorectal cancer has emphasized the need for enhanced surgical training, particularly in Poland, where changes to the training program have increased the number of required intestinal procedures for residents.
  • A multicenter study (LILEO study) involving 199 patients aimed to evaluate ileostomy reversal safety, comparing outcomes between surgeries performed by specialist surgeons and those done by surgical residents.
  • Results showed that while the resident group had a shorter hospital stay and a lower overall complication rate, these differences weren't statistically significant; however, minor complications were more prevalent in the specialist group, indicating that resident-performed ileostomy reversals are safe and effective.

Selected Trace Elements and Their Impact on Redox Homeostasis in Eye Health.

Biomolecules

October 2024

Department of Medical Biology and Biochemistry, Faculty of Medicine, Ludwik Rydygier Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Toruń, 24 Karłowicza St., 85-092 Bydgoszcz, Poland.

Oxidative stress plays a crucial role in the pathogenesis of various ocular degenerative diseases, leading to structural and functional changes in eye tissues. This imbalance between reactive oxygen species (ROS) and antioxidants significantly contributes to conditions such as age-related macular degeneration, diabetic retinopathy, cataracts, and glaucoma. Both enzymatic and nonenzymatic antioxidants are vital for maintaining ocular health by neutralizing ROS and restoring cellular redox balance.

Not all biases are created equal: how to deal with bias on laboratory measurements.

Clin Chem Lab Med

November 2024

Department of Laboratory Medicine, Ludwik Rydygier Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Torun, Bydgoszcz, Poland.

Although the concept of bias appears consolidated in laboratory science, some important changes in its definition and management have occurred since the introduction of metrological traceability theory in laboratory medicine. In the traceability era, medical laboratories should rely on manufacturers who must ensure traceability of their diagnostic medical devices (IVD-MD) to the highest available references, providing bias correction during the trueness transfer process to calibrators before they are marketed. However, sometimes some bias can be observed arising from an insufficient correction during the traceability implementation.

Article Synopsis
  • The study aimed to analyze the demographic and clinical traits of Polish patients with generalized pustular psoriasis (GPP), revealing that most patients are middle-aged women with common comorbidities like hypertension and cardiovascular diseases.
  • A total of 90 patients were examined, who had a median GPP duration of 3 years and experienced an average of 2 flares, often requiring hospitalization; main triggers for flares included medications and infections.
  • The findings showed significant differences, such as younger patients often having GPP alongside psoriasis vulgaris (PV), highlighting a need for better management due to the high hospitalization rate and recurrent flares.

Department of Clinical Immunology, Laboratory of Clinical Immunogenetics and Pharmacogenetics, Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, R. Weigla 12, 53-114 Wroclaw, Poland.

Vitamin D levels have been related to the severity and progression of various autoimmune disorders. In this study, we aimed to investigate the impact of genetic variability in the vitamin D receptor (VDR) gene on disease susceptibility and progression in patients with rheumatoid arthritis (RA) treated with tumor necrosis factor (TNF) inhibitors. The study comprises 121 RA patients subjected to anti-TNF therapy genotyped for four VDR polymorphic variants: rs1544410 (I), rs2228570 (I), rs731236 (I), and rs7975232 (I).

Biogeographical ancestry analysis is valuable in forensic investigations, especially in missing person cases or crimes without eyewitnesses, as it helps to infer geographic origins from genetic markers. This approach enhances forensic efforts by providing essential clues for identifying individuals with limited direct evidence. Slavic-speaking populations are poorly distinguishable based on human genome variability.

The Frozen Elephant Trunk Procedure-8 Years of Experience from Poland.

J Clin Med

October 2024

CAROL-Cardiothoracic Anatomy Research Operative Lab, Department of Cardiovascular Surgery and Transplantology, Institute of Cardiology, Jagiellonian University Medical College, 31-008 Krakow, Poland.

The frozen elephant trunk method combines the implantation of a Dacron prosthesis with a self-expanding stent graft, which allows for complex repairs of the aortic arch and thoracic aorta in one procedure. Despite the advantages of hybrid treatment for aortic arch aneurysms, in Poland, only a few such surgeries are performed annually compared to in Western countries. The aim of this study was to demonstrate the 8-year outcomes of treatment at the center where the Aortic Team operates, which is one of the centers in Poland with the most extensive experience in hybrid FET treatment.
