AI Article Synopsis

  • The study investigates the link between urticaria (a skin condition) and mental disorders, confirming that individuals with urticaria are at a higher risk for conditions like ADHD and schizophrenia.
  • Using data from various genome studies, researchers found that different types of urticaria are associated with specific mental health risks and examined the role of inflammatory cytokines.
  • The findings suggest that inflammatory cytokines do not mediate the relationship between urticaria and mental disorders, indicating a need for integrated treatment approaches that consider both physical and mental health.

Article Abstract

Background: The genetic association between urticaria and mental disorders and whether inflammatory cytokines mediate this process remains unclear.

Materials And Methods: A Mendelian randomization (MR) approaches to elucidate the causal relationship between urticaria and mental disorders and to validate the mediation of inflammatory cytokines. Genome-wide association study (GWAS) databases used were obtained from Psychiatric Genomics Cooperation (PGC), GWAS Catalog, and FinnGen Consortium. Our study was conducted using inverse variance weighted (IVW) and Bayesian weighted MR (BWMR) methods for joint analysis.

Results: The MR results showed that urticaria increased the risk of attention deficit hyperactivity disorder (ADHD) (odds ratio [OR] 1.088, 95% confidence interval [CI]: 1.026-1.154, p 0.0051); cholinergic urticaria increased the risk of bipolar disorder (BD) (OR 1.012, 95% CI: 1.001-1.022, p 0.0274); dermatographic urticaria increased the risk of ADHD (OR 1.057, 95% CI: 1.005-1.112, p 0.0323); idiopathic urticaria increased the risk of schizophrenia (SCZ) (OR 1.057, 95% CI: 1.005-1.112, p 0.0323); other unspecified urticaria increased the risk of ADHD (OR 1.085, 95% CI: 1.023-1.151, p 0.0063). We found that eight inflammatory cytokines were negatively associated with mental disorders and seven inflammatory cytokines were positively associated with mental disorders. Finally, our results suggested that inflammatory cytokines do not act as mediators between urticaria and mental disorders.

Conclusions: Our study reveals a causal relationship between urticaria and the increased risk of mental disorders. We suggest that the treatment of urticaria could incorporate psychiatric interventions and mental health assessment of patients.

Purpose: This systematic review and meta-analysis aimed to assess the gingival crevicular fluid (GCF) level of tumor necrosis factor-alpha (TNF-alpha) as a valuable inflammatory cytokine for estimation of the efficacy of adjunctive antimicrobial photodynamic therapy (aPDT) in stage II-IV periodontitis patients.

Methods: This review was conducted in accordance with the PRISMA statements, and registered in PROSPERO (CRD42022321211). An electronic search was conducted for articles comparing the efficacy of aPDT versus scaling and root planing (SRP) published up until June 2023.

Periodontal ligament fibroblasts (PDLFs) play a crucial role in the etiology of periodontitis and periodontal tissue regeneration. In healthy periodontal tissues, PDLFs maintain the homeostasis of periodontal soft and hard tissues as well as the local immune microenvironment. PDLFs also have the potential for multidirectional transdifferentiation and are involved in periodontal tissue regeneration.

Background: Recent research has postulated that the activation of cGAS-STING-interferon signalling pathways could be implicated in the pathogenesis of Alzheimer's disease (AD). However, the precise types of interferons and related cytokines, both from the brain and periphery, responsible for cognitive impairment in patients with AD remain unclear.

Methods: A total of 131 participants (78 [59.

Background: Malignant pleural mesothelioma (MPM) is a highly chemo-refractory and immune-evasive tumor that presents a median overall survival of 12-14 months when treated with chemotherapy and immunotherapy. New anti-tumor therapies as well as the concomitant reactivation of immune destruction are urgently needed to treat patients with this tumor. The aim of this work is to investigate the potential effect of ecteinascidin derivatives as lurbinectedin as new first-line treatment option in MPM, alone and in combination with immunotherapy.
