The emerging role of epigenetics in the pathogenesis of autoimmune diseases has recently attracted much interest on the possible use of epigenetic modulators for the prevention and treatment of these diseases. In particular, we and others have shown that drugs that inhibit DNA methylation, such as azacitidine (AZA) and decitabine (DAC), already used for the treatment of acute myeloid leukemia, exert powerful beneficial effects in rodent models of type 1 diabetes, multiple sclerosis, and Guillain Barrè syndrome. Along this line of research, we have presently studied the effects of DAC in a murine model of rheumatoid arthritis induced by type II collagen and have demonstrated that DAC administration was associated with a significant amelioration of the clinical condition, along with in vivo and ex vivo modification of the immunological profile of the so-treated mice, that exhibited a diminished production of Th1 and Th17 pro-inflammatory cytokines and reduction of anti-type II collagen autoantibodies.

Developing translational nanoradiosensitizers with multiple activities in sensitizing tumor cells and re-shaping tumor immunosuppressive microenvironments are urgently desired for addressing the poor therapeutic efficacy of radiotherapy in clinic. Inspired by the anaerobic and immunoagonist properties of the probiotic (bifidobacterium longum, BL), herein, a biomimetic Selenium nanoradiosensitizer in situ-formed on the surface of the probiotic (BL@SeNPs) is developed in a facile method to potentiate radiotherapy. BL@SeNPs selectively target to hypoxia regions of tumors and then anchor on the surface of tumor cells to inhibit its proliferation.

Purpose: Responsive neurostimulation of the centromedian nucleus of the thalamus (CM RNS) is being investigated for treatment of drug-resistant generalized epilepsy with promising results. The aim of this study is to report outcomes of seven patients with pediatric-onset drug-resistant generalized epilepsy, including both genetic generalized epilepsy (GGE) and Lennox-Gastaut syndrome (LGS), who underwent treatment with bilateral CM RNS.
Methods: A retrospective chart review was performed for patients with drug-resistant generalized epilepsy who underwent treatment with bilateral CM RNS at Children's Hospital of Pittsburgh from 2020 to 2022.
How therapist effects shape pain-related outcome improvement in psychological treatments for chronic pain.
Curr Opin Psychol

Department of Rehabilitation Medicine, The University of Washington, Seattle, WA, USA.
Psychological chronic pain treatments have variable efficacy across individual patients, and on average tend to produce modest effects. In order to improve treatment outcomes, the past decade has seen a rapid increase in research focused on determining the mechanisms underlying treatment-related gains. The near exclusive focus of this research has been on uncovering patient-related mediators and moderators.

Objective: Deep neck infection with abscess (DNI) may cause dysphagia as a late complication. This study aimed to determine the rate of DNI related dysphagia (DNIRD) and the effectiveness of rehabilitation and surgery for DNIRD.
Methods: As a multicenter retrospective study, we conducted a nationwide survey by sending questionnaires to specialist training institutions certified by the Japan Broncho-esophagological Society (JBES).
Are glucagon-like-peptide-1 (GLP-1) receptor agonists useful in treating Parkinson's disease (PD). Does the clinical trial with lixisenatide add anything?
Expert Opin Investig Drugs
January 2025
School of Pharmacy and Medical Sciences, Griffith University, Brisbane, Australia.
Introduction: Parkinson's disease (PD) is a common neurodegenerative disease. Glucagon-Like-Peptide-1 (GLP-1) receptor agonists decrease the incidence of developing PD, and are being considered for the treatment of PD.
Areas Covered: A phase 2 clinical trial of lixisenatide, a GLP-1 receptor agonist, in the early stages of PD.
