Mechanistic Insights and Molecular Diagnostics of TMPRSS2-ERG: Overview of the Journey from Regulation of Signaling Landscape in Fusion Positive Prostate Cancer to Appraisal as a Diagnostic Marker.

Chromosomal rearrangements and recurrent gene fusions were previously presumed to be the primary oncogenic mechanisms of hematological malignancies. However, the discovery of gene fusions in different cancers has opened new horizons to comprehensively investigate how cell type-specific fusion oncoproteins modulate signaling cascades. Prostate cancer (PCa) is a multifaceted and therapeutically challenging disease, and functional genomics have helped us develop a better understanding of the mechanisms underlying prostate carcinogenesis, castration-resistant PCa, and metastasis.

Inflammatory Manifestations Associated With Gut Dysbiosis in Alzheimer's Disease.

Recent studies strongly suggest that gut microbiome can influence brain functions and contribute to the development of Alzheimer's disease (AD). However, reported changes in the gut microbiomes in AD patients from different countries are not similar, and more research is needed to reveal the relationships between human microbiomes and AD in diverse ethnic populations. There is also an assumption that microbiome-associated peripheral inflammation might drive the development of sporadic AD.

Oral Microbiome Stamp in Alzheimer's Disease.

Recent studies have suggested that periodontal disease and alterations in the oral microbiome may be associated with cognitive decline and Alzheimer's disease (AD) development. Here, we report a case-control study of oral microbiota diversity in AD patients compared to healthy seniors from Central Asia. We have characterized the bacterial taxonomic composition of the oral microbiome from AD patients (n = 64) compared to the healthy group (n = 71) using 16S ribosomal RNA sequencing.

Association of Insomnia with Anxiety and Depression in Type 2 Diabetic Patients: A Cross-Sectional Study.

Background: Type 2 diabetes mellitus (T2DM) is associated with sleep disorders, which in turn may lead to anxiety and depression. Sleep deprivation impairs glucose metabolism causing a decrease in insulin sensitivity and glucose tolerance. The present study aimed to determine the association of insomnia with anxiety and depression in patients with T2DM.

The Distribution of the Genotypes of and Polymorphisms in Kazakhstani Patients with Atrial Fibrillation Treated with DOAC.

Nowadays, direct oral anticoagulants (DOACs) are the first-line anticoagulant strategy in patients with non-valvular atrial fibrillation (NVAF). We aimed to identify the influence of polymorphisms of the genes encoding P-glycoprotein () and carboxylesterase 1 () on the variability of plasma concentrations of DOACs in Kazakhstani patients with NVAF. We analyzed polymorphisms rs4148738, rs1045642, rs2032582 and rs1128503 in and rs8192935, rs2244613 and rs71647871 genes and measured the plasma concentrations of dabigatran/apixaban and biochemical parameters in 150 Kazakhstani NVAF patients.

Acquired Hallux Varus. Etiology, Pathology, Classification, and Treatment Algorithm. Literature Review.

Iatrogenic hallux varus is formed due to an imbalance between the bone, tendon, and ligamentous-articular structures in the first metatarsophalangeal joint (MJ), with the progression of the medial deviation of the big toe. A secondary factor is an imbalance between excessive medial tension and weakness or excessive soft tissue release of lateral capsular-ligamentous structures. The article is devoted to a rare but no less complex postoperative complication of hallux valgus deformity, acquired hallux varus.

Study of gut microbiota alterations in Alzheimer's dementia patients from Kazakhstan.

We have investigated the diversity and composition of gut microbiotas isolated from AD (Alzheimer's disease) patients (n = 41) and healthy seniors (n = 43) from Nur-Sultan city (Kazakhstan). The composition of the gut microbiota was characterized by 16S ribosomal RNA sequencing. Our results demonstrated significant differences in bacterial abundance at phylum, class, order, and genus levels in AD patients compared to healthy aged individuals.

The Technique of Mobilization of the Colon for Pull-Through Procedure in Hirschsprung's Disease.

Background: In patients with Hirschsprung's disease (HD), persistent obstructive symptoms may develop after surgery. The causes of mechanical obstruction may be a retraction of the pulled-through bowel due to insufficient mobilization of the mesentery or impaired blood supply in the area of the coloanal anastomosis in the case of excessive ligation of the supplying vessels. Leakage and stenosis are formidable complications and require repeated surgical intervention.
