Background: Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, which is characterized by a lack of sensitive and specific biomarkers.

Objectives: This study investigates the association between ELAV-like RNA binding protein 1 (ELAVL1) and HCC patient outcomes.

Material and methods: This retrospective study encompassed 108 HCC patients who reported to Wuhan Fourth Hospital and Tongji Hospital, China, from January 2016 to August 2020. Clinical data collected included age, sex, body mass index (BMI), comorbidities, tumor-node-metastasis (TNM) stage, Barcelona Clinic Liver Cancer (BCLC) stage, and lymphatic metastasis. All patients received routine follow-up for survival and recurrence status ranged from 36 to 60 months. The serum levels of ELAVL1 were tested using enzyme-linked immuno-sorbent assay (ELISA). Levels of total bilirubin, alanine aminotransferase (ALT), aspartate transaminase (AST), HCC-related biomarkers of alpha fetoprotein (AFP), α-L-fucosidase (AFU), and carcinoembryonic antigen (CEA) were recorded.

Results: Our findings revealed a significantly higher expression of ELAVL1 in patients presenting with TNM stages III-IV, BCLC stages C-D, lymphatic metastasis, as well as deceased and recurrent patients. Receiver operating characteristic (ROC) curves showed that the areas under the curve (AUCs) for ELAVL1 in predicting mortality, recurrence and poor prognosis (defined as mortality or recurrence) in HCC patients were 0.818, 0.732 and 0.827, respectively. Patients with higher expression of ELAVL1 showed significantly higher frequencies of TNM III-IV stages, BCLC D stage, lymphatic metastasis, higher mortality, and recurrence ratio, as well as higher AFP and CEA levels. ELAVL1 was positively correlated with levels of AFP and CEA. Higher BCLC stage, lymphatic metastasis, age, AFP, and ELAVL1 were independent risk factors for poor prognosis of HCC patients.

Conclusions: Higher serum levels of ELAVL1 are associated with worse clinical outcomes and poorer prognosis in ‑HCC patients.

Background: The neuroendocrine system's role in maintaining bodily homeostasis implicates it in insomnia, suggesting both causal relationships and therapeutic targets. Yet, studies examining the link between metabolic syndrome (MetS) components such as hypertension, elevated blood glucose levels and abnormal cholesterol and insomnia have been inconsistent. Some research suggests a correlation, proposing that metabolic dysfunctions might contribute to sleep disturbances. However, other studies found little to no significant connection, indicating the complexity of this relationship and the potential influence of genetic, lifestyle and environmental factors. These contradictory findings underscore the challenges in fully understanding the intricate interplay between metabolic health and sleep quality.

Objectives: To explore the relationship between MetS and insomnia.

Material and methods: This study used bidirectional two-sample Mendelian randomization (MR) analysis to determine the causal relationship between the characteristics of MetS components and insomnia. Based on Genome-Wide Association Studies (GWAS) public databases, we explored the causal relationship between waist circumference (WC), hypertension, triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), and the risk of insomnia. Sensitivity analysis was conducted to evaluate the stability, heterogeneity and potential presence of horizontal pleiotropy in the results.

Results: Waist circumference and hypertension were associated with an increased risk of insomnia (WC, odds ratio (OR) = 1.05, 95% confidence interval (95% CI): 1.03-1.06, p = 9.15e-07; hypertension, OR = 1.06, 95% CI: 1.02-1.10, p = 0.005). In the reverse MR analysis, there was no significant causal relationship between insomnia and WC, TG, HDL-C, and FBG.

Conclusions: Our study has demonstrated the close connection between MetS components and insomnia by genetic means, thereby guiding the future research direction of insomnia prevention and treatment.

Background: High sepsis mortality rates pose a serious global health problem. Machine learning is a promising technique with the potential to improve mortality prediction for this disease in an accurate and timely manner.

Objectives: This study aimed to develop a model capable of rapidly and accurately predicting sepsis mortality using data that can be quickly obtained in an ambulance, with a focus on practical application during ambulance transport.

Material and methods: Data from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) dataset were used to compare the performance of 11 machine learning algorithms against the widely utilized quick Sequential Organ Failure Assessment (qSOFA) score. A dynamic updating model was implemented. Performance was evaluated using area under the curve (AUC) and precision-recall area under the curve (PRAUC) scores, and feature importance was assessed with SHapley Additive exPlanations (SHAP) values.

Results: The light gradient boosting machine (LightGBM) model achieved the highest AUC (0.79) and PRAUC (0.44) scores, outperforming the qSOFA score (AUC = 0.76, PRAUC = 0.40). The LightGBM also achieved the highest PRAUC (0.44), followed by Optuna_LightGBM (0.43) and random forest (0.42). The dynamically updated and tuned model further improved performance metrics (AUC = 0.79, PRAUC = 0.44) compared to the base model (AUC = 0.76, PRAUC = 0.39). Feature importance analysis offers clinicians insights for prioritizing patient assessments and interventions.

Conclusions: The LightGBM-based model demonstrated superior performance in predicting sepsis-related mortality in an ambulance setting. This study underscores the practical applicability of machine learning models, addressing the limitations of previous research, and highlights the importance of real-time updates and hyperparameter tuning in optimizing model performance.

Background: Pulpal vitality is important for the tooth to maintain its physiological function and preserve its structure.

Objectives: The aim of this study was to evaluate the clinical and radiographic 6- and 12-month treatment success of calcium hydroxide (CH) and calcium silicate materials in indirect pulp treatment (IPT) and direct pulp capping (DPC) in teeth with deep dentin decay.

Material and methods: The study included 143 teeth of patients aged 17-69 years with no systemic disease. The study is grouped under 3 main groups (Dycal, Biodentine, TheraCal PT). Direct pulp capping was applied to 65 teeth and IPT to 66 teeth. All teeth were restored with Universal adhesive system and Universal composite (G-Premio Bond; GC Corp., Tokyo, Japan).

Results: In the statistical evaluations of the data obtained, 0.05 was accepted as the level of statistical significance. The general success rate in the IPT group was found to be 95.2% for Biodentine (Septodont, SaintMaur-des-Fossés, France), 91.7% for Dycal (Dentsply/Caulk, International Inc. Milford, USA) and 90.1% for TheraCal PT (Bisco Inc., Schaumburg, USA) at both 6 and 12 months. When the clinical and radiographic success was compared at 6 months and 12 months, no statistically significant difference was determined between the materials (p > 0.05). In the clinical and radiographic evaluations at the end of 6-month follow-up in the DPC group, the success rates were determined to be 96.0% for Biodentine, 81.8% for Dycal and 63.2% for TheraCal PT. At 12 months, these rates were 96.0% for Biodentine, 68.2% for Dycal and 63.2% for TheraCal PT. DPC Biodentine was found to be the most successful material (96.0%).

Conclusions: At the end of the 12-month follow-up period, it was considered that the 3 materials (Biodentine, Dycal, TheraCal) can be selected for IPT. In DPC, Biodentine was found to be more successful than both calcium silicate containing resin and CH.

Background: Immunosuppressive therapy in organ transplant ensures proper graft function for many years, but it is burdened with a negative impact on the development of skin cancer in them.

Objectives: To characterize the impact of immunosuppressive therapy in transplant recipients on the development of non-melanoma skin cancers (NMSC).

Material and methods: A total of 17,207 Polish patients who underwent liver, heart or kidney transplants between 2010 and 2022 and were on immunosuppression were included in the study. Immunosuppression was most commonly achieved using a regimen of tacrolimus (TAC) or cyclosporine A (CsA) combined with mycophenolic acid (MPA) and glucocorticosteroids (GS). Data on NMSC incidence from the National Health Fund in this population were analyzed and compared against incidence of NMSC in general Polish population in the same period.

Results: Renal transplant recipients demonstrated a significantly elevated risk of NMSC compared to the general population, with a 1-year cumulative incidence of 0.09% vs 0.04% (p < 0.001), a 5-year incidence of 1.21% vs 0.18% (p < 0.001) and a 10-year incidence of 4.18% vs 0.36% (p < 0.001). Liver transplant recipients exhibited an elevated risk for the development of NMSC, which persisted and increased over time (incidence of 0.09% vs 0.04% at 1 year (p < 0.001), 0.83% vs 0.18% at 5 years (p < 0.001) and 2.65% vs 0.36% at 10 years (p < 0.001)). Heart transplant recipients also showed a significantly higher cumulative incidence of NMSC at 1 year (0.09% vs 0.04%, p < 0.001), 5 years (0.89% vs 0.18%, p < 0.001) and 10 years (4.06% vs. 0.36%, p < 0.001) post-transplantation.

Conclusions: Organ transplant recipients have an 2 times at 1 year, 4,5 times after 5 years and 9 times after 10 years increased risk of NMSC on average as opposed to general Polish population in the same period.

Distal biceps tendon rupture is a rare injury predominately occurring in middle-aged men. This study aimed to collect relevant risk factors associated with distal biceps tendon rupture from the published literature. This systematic review aimed to collect and tabulate the risk factors for distal biceps tendon rupture. Studies published in English were searched concerning risk factors for distal biceps tendon ruptures until July 2022; cohort studies, case series and randomized controlled trials were subjected to analysis. Case studies, cadaveric studies and reviews in any form were excluded. The studies were quantitatively and qualitatively reviewed. One hundred twenty-one articles presenting risk factors for distal biceps tendon ruptures were identified, recruiting a total of 7,484-7,576 patients. The average age of the individuals was 46.8 years, with 96.7% being males and 94.7% having affinity for sports activities. In 56.7% of the cases, the dominant arm was involved, and in 54.6%, the right arm was affected. The use of tobacco was found in 20.8% of cases and of anabolic steroids in 2.5% of cases. On average, 55.8% of distal biceps tendon rupture patients had a physical occupation and the most common mechanism of the injury was related to heavy weight lifting observed in 53.2% of subjects. The most common and outstanding reported risk factors for distal biceps tendon ruptures were age, sex and sports activity, i.e., middle-aged males being still physically active and practicing sports. Steroid usage does not seem to increase significantly the risk of the distal biceps tendon rupture.

This narrative review provides an overview of scientific studies on dietary supplements that may affect circulating testosterone (T) levels to explore which substances are scientifically proven to increase T concentration. We also review the scientific literature for their potential mechanisms and laboratory test changes triggered by their use. Based on the analysis of existing data on substances used to increase endogenous T levels, especially double-blind placebo-controlled randomized clinical trials, we selected 2 herbal extracts with the best documented positive effects on T levels, Withania somnifera root and root extracts/leaves and seed extracts of Trigonella foenum-graecum. Although these substances have different postulated mechanisms of action, both significantly increase T levels in men. Withania somnifera may inhibit the effects of cortisol and prolactin on the hypothalamic-pituitary-gonadal axis and directly affect the hypothalamus. Trigonella foenum-graecum seeds contain the active substance diosgenin, which is a precursor for sex hormone synthesis in gonads.

The establishment of the first JBI Affiliated group in Poland at Wroclaw Medical University marks a significant advancement in evidence-based healthcare (EBHC) nationally. This editorial explores the evolution of EBHC and the critical role of JBI in driving its progress. Founded in 1996 as a research institute at the Royal Adelaide Hospital in South Australia and now based at the University of Adelaide, JBI has emerged as an international leader in evidence synthesis, transfer and implementation. Its Feasibility, Appropriateness, Meaningfulness, and Effectiveness (FAME) framework highlights the feasibility, appropriateness, meaningfulness, and effectiveness of healthcare practices, ensuring that decisions are patient-centered and contextually relevant. JBI's global collaboration network encompasses over 85 entities, with 23 located in Europe, emphasizing the importance of cultural inclusivity and international partnerships. Recent initiatives include translating the JBI Model of into Polish, German and Czech, linking global knowledge to local contexts, and enhancing understanding for professionals and students alike. This editorial also underscores the collaborative achievements of JBI entities in Wroclaw, Brandenburg an der Havel, Prague, and Olomouc. These partnerships have propelled regional implementation, research and education, fostering a shared vision for elevating healthcare quality. Launching a new EBHC section in the Advances in Clinical and Experimental Medicine journal is a significant step forward, inviting global contributions and stimulating innovation and knowledge sharing in EBHC. The presence of a JBI Affiliated group at Wroclaw Medical University symbolizes a transformative commitment to excellence and collaboration. It sets new benchmarks for healthcare in Poland and beyond while reinforcing the global mission of evidence-based practice.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a complex multifactorial etiology that develops as a result of autoimmune processes, leading to widespread inflammation and malfunction of multiple tissues and organs, and, as a consequence, triggers arterial hypertension, conduction disorders, valvular heart disease, pulmonary hypertension (PH), and venous thromboembolism events (VTE), contributing to increased mortality. Moreover, autoimmune abnormalities can accelerate atherogenesis and lead to many SLE manifestations, including coronary artery disease (CAD) and cerebrovascular events. The current review aimed to systematize existing data from the latest works and summarize published guidelines and recommendations. In particular, the prevalence of cardiovascular disorders in SLE patients, advances in diagnostics (including imaging methods and biomarker laboratory testing), the possible future direction of therapy, and the latest European Alliance of Associations for Rheumatology (EULAR) guidelines for optimal management of cardiovascular risk in SLE were overviewed.

Background: Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic condition with relapsing-remitting course. Diarrhea and abdominal pain are the most common IBD symptoms. Fibroblast growth factor 19 (FGF19) is an endocrine factor that inhibits hepatic bile acid production and may be used as a diagnostic marker for bile acid malabsorption.

Objectives: To assess serum FGF19 levels in active and inactive phases of IBD and find a potential correlation between FGF19 and disease activity.

Material and methods: Fasting serum FGF19 levels were measured in 105 IBD patients (47 UC patients, 41 CD patients without previous ileocecal resection (NR-CD), 17 CD patients after ileocecal resection (IR-CD), and 17 control subjects). The disease activity was assessed using clinical, laboratory and endoscopic criteria.

Results: Inverse correlations were found between FGF19 level and intensity of diarrhea (in UC), abdominal pain intensity (in UC and IR-CD) and inflammatory markers (in UC and IR-CD). Moreover, FGF19 concentration was inversely correlated with clinical and endoscopic activity indices in UC and CD.

Conclusions: Fluctuations in FGF19 level related to clinical and endoscopic activity of UC and CD revealed a clear pattern of higher values in remission than in active disease phases. Fibroblast growth factor 19 may serve as a potential diagnostic biomarker and constitute a new therapeutic target in IBD.
