Interplay of NF-κB and PPAR-γ transcription factors in patients with juvenile systemic lupus erythematosus.

Objective: Juvenile SLE (jSLE) is an autoimmune disease characterised by the presence of high levels of autoantibodies, predominantly targeting nuclear antigens, resulting in a breakdown of self-tolerance. However, its pathogenesis is multifactorial and poorly understood. The aim of this study was to evaluate the potential of nuclear factor-kappa B (NF-κB) and peroxisome proliferator-activated receptor-gamma (PPAR-γ) as biomarkers for jSLE.

miR-21 and cathepsin B in familial Mediterranean fever: novel findings regarding their impact on disease severity.

Objective: The limited predictive effect of genotype on familial Mediterranean fever (FMF) phenotype suggests that epigenetic factors and alternative mechanisms that may cause IL-1β release could contribute to phenotypic heterogeneity. The objective of this study was to examine the role of IL-1β levels and miR-21-5p, cathepsin B and pyrin levels, which were identified as potential factors causing IL-1β release through the use of bioinformatics tools, in the pathogenesis of FMF and their relationship with disease severity.

Materials And Methods: 50 paediatric patients with FMF and 40 healthy children were enrolled in this study.

[Multicentric Screening of Local Antibiotic Resistance in Uncomplicated Urinary System Infections: 1850 Patients from 37 Centers].

This study was aimed to identify the most frequently observed pathogens in uncomplicated urinary tract infections from outpatient urinary isolates obtained across seven different geographical regions in Türkiye and to determine whether the antibiotic resistance rates of these pathogens differ significantly between these regions. The study included patients aged 18 to 65 years who were diagnosed with uncomplicated urinary tract infections and had positive urine cultures from March 2021 to August 2022, across 37 different centers in Türkiye. The participating centers were selected based on their use of the disk diffusion method, in line with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines, to ensure standardization of urine culture data.

The objective is to assess the activation and implementation of the hospital disaster plan amidst the ongoing pandemic.

Multimodality Imaging in Cardiomyopathies.

Cardiomyopathy, which is shortly defined as a disease of the myocardium, has a broad definition that includes many different diagnoses. Recent advances in cardiac imaging techniques, including basic and advanced echocardiography, computed tomography, nuclear medicine, and cardiac magnetic resonance, allow for a more accurate evaluation of volumes and thickness of cardiac chambers, systolic and diastolic function of the ventricules, and tissue structure. Multimodality imaging often provides the first clinical suspicion for specific etiologies, especially when the medical and family history is unclear, by identification of red flags of underlying systemic diseases.

Factors Associated with the Development of Anti-drug Antibodies to TNFi and the Consequences for Axial Spondyloarthritis: A Two-year Follow-up Study.

Objective: To evaluate the development of anti-drug antibodies (ADAb) against tumor necrosis factor inhibitors (TNFi) therapy during a 2-year period and search the factors linked to patients with axial spondyloarthritis (axSpA).

Methods: Biologic-naive patients with axSpA were included in this observational study. Serum drug levels and ADAb were measured at weeks 12, 24, 52, and 104 of treatment by enzyme-linked immunosorbent assay (ELISA).

Therapeutic implications of etiology-specific diagnosis of early-onset developmental and epileptic encephalopathies (EO-DEEs): A nationwide Turkish cohort study.

Objective: To evaluate the etiology-specific diagnosis of early-onset developmental epileptic encephalopathies (EO-DEEs) in a nationwide Turkish cohort to determine the implications for therapeutic management.

Methods: The cohort comprised 1450 patients who underwent EO-DEE. The utility of genetic testing was assessed with respect to the initial phases of next generation sequencing (NGS) (2005-2013) and the current NGS era (2014-2022).

Evaluation of the teratogenic effects of pregabalin usage during pregnancy: A multicenter case-control study.

Objective: Information regarding pregabalin use is limited. We aimed to assess the outcome of the patients who have taken pregabalin at a certain time during their pregnancies.

Methods: 31 patients used pregabalin treatment during pregnancy and 93 control patients were included in the study who applied to hospital between the years 2013-2022.

Caffeine mitigates tamoxifen-induced fatty liver in Wistar rats.

Purpose: Tamoxifen, a widely used drug for breast cancer treatment, is associated with adverse effects on the liver, including the development of fatty liver. This study aimed to investigate the potential protective effect of caffeine against tamoxifen-induced fatty liver in Wistar rats.

Methods: Rats were divided into normal control, tamoxifen + saline, and tamoxifen + caffeine.

Efficacy and Safety of Tofacitinib in Patients with Psoriatic Arthritis or Ankylosing Spondylitis by Cigarette Smoking Status.

Introduction: Routine care studies of psoriatic arthritis (PsA) and ankylosing spondylitis (AS) demonstrated attenuated responses to tumor necrosis factor inhibitors in current/past versus never smokers.

Preconditioning of Human Umbilical Cord Mesenchymal Stem Cells with a Histone Deacetylase Inhibitor: Valproic Acid.

Background: Mesenchymal stem cells (MSCs) play a key role in regenerative medicine due to their capacity to differentiate into multiple cell lines, regulate the immune system, and exert paracrine effects. The therapeutic impact of MSCs is primarily mediated through their secretome. The secretory and therapeutic potential of MSCs can be improved through preconditioning, which entails the application of hypoxic environments, 3-dimensional cell cultures, and pharmacological agents.
