This study examines the impact of zinc, copper, cobalt, iron, and manganese on cancer development, considering their dual roles as potential promoters or inhibitors within tumorigenesis. A comprehensive analysis of existing literature and experimental data is conducted to elucidate the intricate relationship between these trace elements and cancer progression. The findings highlight the multifaceted effects of zinc, copper, cobalt, iron, and manganese on various aspects of cancer development, including cell proliferation, angiogenesis, and metastasis. Understanding the nuanced interactions between these trace elements and cancer could offer crucial insights into tumorigenesis mechanisms and facilitate the identification of novel biomarkers and therapeutic targets for cancer prevention and treatment strategies. This research underscores the importance of considering the roles of essential trace elements in cancer biology and may ultimately contribute to advancements in precision medicine approaches for combating cancer.

Schizophrenia is a complex neuropsychiatric disorder characterized by a diverse range of symptoms, including positive, negative symptoms such as alogia, anhedonia, avolition, and affective flattening, cognitive symptoms, and emotional symptoms as a separate domain. Emerging evidence suggests that oxidative stress and neuroinflammation play crucial roles in the etiopathogenesis of schizophrenia. The aim of this review is the interplay between oxidative stress—defined as an imbalance between reactive oxygen species (ROS) production and antioxidant defenses—and neuroinflammatory processes within the central nervous system. Studies indicate that elevated levels of oxidative markers and pro-inflammatory cytokines are commonly observed in individuals with schizophrenia, pointing to a potential pathophysiological link. The dysregulation of redox homeostasis may exacerbate neuroinflammatory responses, contributing to neuronal damage and the subsequent manifestation of psychiatric symptoms. Furthermore, genetic and environmental factors may interact with these biological processes, influencing individual susceptibility to schizophrenia. Understanding the mechanisms by which oxidative stress and neuroinflammation contribute to the development and progression of schizophrenia could pave the way for novel therapeutic strategies aimed at mitigating these pathological processes and improving patient outcomes.

Aim: The aim of the study was to assess whether virtual reality (VR) rehabilitation would be an effective adjunct to standard therapy in improving outcomes in stroke patients. The secondary objective was to investigate whether VR therapy would improve quality of life and reduce pain levels compared to traditional rehabilitation.Material and methods: The study was conducted with stroke patients undergoing rehabilitation at the Department of Rehabilitation and Orthopedics. The collected data were randomly divided into two groups: an experimental group that received VR-assisted rehabilitation and a control group that received only conventional rehabilitation for two weeks, six days a week. The outcome measures in determining the effectiveness of rehabilitation were the EQ-5D and VAS scales.Results: There were no significant differences between the experimental and control groups in terms of quality of life and pain scores. However, both groups showed improvement over time, indicating overall effectiveness of the rehabilitation. The experimental group showed significant improvement in pain reduction, suggesting a beneficial effect of VR therapy. The small sample size limited the detection of significant differences between groups.Conclusions: VR-assisted rehabilitation may help reduce pain in stroke patients, but its impact on overall quality of life remains uncertain. Further studies with larger groups and longer follow-up are needed to fully understand the potential of VR to improve conventional rehabilitation practices.

Aim: The aim of this review article is to conduct a thorough analysis of scientific publications on the importance of lifestyle, diet, and physical activity in the prevention and rehabilitation of people with chronic diseases. Material and methods: The review article takes into account obesity, type 2 diabetes, and cardiovascular disease due to the high prevalence of these chronic diseases on a global scale. The study is based on a thorough analysis of publications containing up-to-date information on healthy behaviors in people struggling with chronic diseases. The results clearly indicate the positive aspects of leading a healthy lifestyle. It is worth noting that regular exercise, a balanced and nutritious diet, health education, and psychological support have a huge impact on the health of people with chronic diseases. The article also emphasizes the importance of following recommendations, regular check-ups, and appropriate patient motivation under the supervision of medical staff. Conclusions: The review article clearly indicates that the lifestyle of patients with chronic diseases has a significant impact on their quality of life. Prevention and rehabilitation play a key role in reducing the risk of developing chronic diseases or slowing down their progression.

Aims: This review analyzes and deepens our understanding of the anatomical variations of the hepatopancreatic region, a crucial area in many medical fields. Precision and surgical efficiency largely rely on a thorough understanding of anatomical nuances and variations. In recent years, significant emphasis has been placed on exploring anatomical variations, particularly in the context of hepatopancreatic surgery. Material and methods: This review collects key information on the types of lesions within the major vessels of the liver and pancreas and presents their incidence. The cited material is based on a review of studies and observations, textbooks, and other review articles. Conclusions: The collected data highlight the importance of hepatic and pancreatic vascular variability, which should be considered an anatomical feature rather than an exception. Further exploration of the occurrence of such features is crucial. This understanding of anatomy is particularly crucial in hepatobiliary and pancreatic surgery, where anatomical complexity directly impacts procedural planning and surgical strategy.
