Currently, seven molecular subtypes of prostate cancer (PCa) are known, the most common of which being the subtype characterized by the presence of the TMPRSS2-ERG fusion transcript. While there is a considerable amount of work devoted to the influence of this transcript on the prognosis of the disease, data on its role in the progression and prognosis of PCa remain controversial. The present study is devoted to the analysis of the association between the TMPRSS2-ERG transcript and the biochemical recurrence of PCa. The study included two cohorts: the RNA-Seq sample of Russian patients with PCa ( = 72) and the TCGA-PRAD data ( = 203). The results of the analysis of the association between the TMPRSS2-ERG transcript and biochemical recurrence were contradictory. The differential expression analysis (biochemical recurrence cases versus biochemical recurrence-free) and the gene set enrichment analysis revealed a list of genes involved in major cellular pathways. The , , , and genes were selected as predictors of the potential prognostic model (AUC = 1.000 for a cohort of Russian patients with PCa and AUC = 0.779 for a TCGA-PRAD cohort).

Liver transplantation (LTx) is increasingly used in Urea Cycle Defects (UCDs) to prevent recurrent hyperammonemia and related neurological irreversible injury. Among UCDs, argininosuccinate lyase deficiency (ASLD) has a more complex phenotype than other UCDs, with long-term neurocognitive deficits. Therefore, the role of LTx in ASLD is still debated.

Objective: Survivors of pediatric head and neck rhabdomyosarcoma (HNRMS) are at risk of developing endocrinopathies following local treatment, resulting from radiation damage to the pituitary gland, hypothalamus, or thyroid gland, often at a young age. Our aim was to determine the prevalence of endocrine dysfunction in long-term HNRMS survivors and compare the prevalence of anterior pituitary insufficiency (API) among different local treatment strategies: external beam radiation with photons, external beam radiation with protons, microscopically radical surgery combined with external irradiation, and macroscopic radical surgery combined with brachytherapy.
Design And Methods: Head and neck rhabdomyosarcoma survivors treated between 1993 and 2017, with ≥2 years of follow-up, without recurrent disease or secondary malignancy were eligible for this study.

Background: Functional abdominal pain disorders (FAPDs) are common in young people and are characterized by persistent or recurrent abdominal symptoms without apparent structural or biochemical abnormalities. FAPDs are associated with diminished quality of life, school absence, increased health care use, and comorbid anxiety and depression. Exposure-based internet-delivered cognitive behavioral therapy (ICBT) has demonstrated efficacy in alleviating abdominal symptoms and improving quality of life.

: Prostate cancer is one of the most commonly diagnosed cancers in the male population and the fifth leading cause of cancer death worldwide in men as of 2022. One of the potential biomarkers that can predict the progression of the disease is the transmembrane adhesion molecule CD44s. The aims of this study were to determine the expression of CD44s in prostate cancer in the central tumor mass and in the tumor periphery of the disease and to compare it with the clinicopathological parameters (PSA, Gleason score, surgical margins, and biochemical recurrence of the disease) in patients treated with radical prostatectomy.

Higher intraoperative opioid doses may be associated with worse long-term oncological outcomes after radical prostatectomy (RP) for prostate cancer. We aimed to evaluate the impact of higher doses of intraoperative opioids and type of anesthesia on biochemical recurrence (BCR) and mortality after RP in a high-volume tertiary center. All patients underwent RP at our center between 2015 and 2021.
