Background And Objective: Chronic pain represents a major global health issue in terms of psycho-physiological, therapeutic, and economic burden, not limited to adults but also to the pediatric age. Despite its great impact, its molecular mechanisms have still not been completely unraveled. Focusing on the impact of epigenetics in the pain complex trait, we assessed the association between chronic pain and the methylation pattern of TRPA1, a key gene related to pain sensitivity.
Methods: We conducted a systematic review retrieving articles from three different databases. After deduplication, 431 items were subjected to manual screening, and then 61 articles were selected and screened again. Of these, only six were maintained for meta-analysis and analyzed using specific R packages.
Results: Six articles were divided into two groups (group 1: comparison of mean methylation levels between healthy subjects and patients with chronic pain; group 2: correlation between mean methylation levels and pain sensation). A non-significant mean difference was obtained from the analysis of group 1 with a value of 3.97 (95% C.I. -7.79; 15.73). Analysis of group 2 showed a high level of variability between studies (correlation = 0.35, 95% C.I. -0.12; 0.82) due to their heterogeneity (I = 97%, < 0.01).
Conclusions: Despite the high variability observed in the different studies analyzed, our results suggest that hypermethylation and increased pain sensitivity could be connected, possibly due to the variation of TRPA1 expression.

Background: The nod-like receptor family pyrin domain-containing 3 (NLRP3) has been implicated in various skin diseases. However, its role in mediating 2, 4-dinitrofluorobenzene (DNFB)-induced chronic itch remains unclear.
Methods: Widetype () and deletion ( )mice, the expression of transient receptor potential (TRP) ankyrin 1 (TRPA1) inhibitor or recombinant mice interleukin-18 (IL-18) were used to establish and evaluate the severity of DNFB-mediated chronic itch.

Objective: To investigate the correlation between endometriosis (EMs) severity and placenta accreta spectrum (PAS) risk in the subsequent pregnancy.
Method: Clinical records of 2,142 patients who underwent laparoscopic surgery for EMs at Fujian Provincial Maternal and Child Health Hospital from January 2014 to January 2018, who had achieved pregnancy and were delivered, were analyzed. Baseline data, EMs stage, The Revised American Fertility Society (R-AFS) score, levels of serum indexes, and pregnancy and neonatal outcomes were recorded.

In 2018, the Veterans Health Administration (VHA) established the original 19 Headache Centers of Excellence (HCoE) program, and an evaluation center. This study utilized a Veteran engagement group method to elicit input from Veteran patients living with chronic headache on daily needs, social determinants of health, and preferences and suggestions for headache programs, services, and research priorities. Four engagement groups were conducted between July 13 and August 22 of 2022 with Veterans who experience headache and received care at a VHA HCoE.

Background: Pain of a chronic nature remains the foremost concern in tertiary spine clinics, yet its elusive nature and quantification challenges persist. Despite extensive research and education on low back pain (LBP), the realm of diagnostic practices lacks a unified approach. Clinically, LBP exhibits a multifaceted character, encompassing conventional assessments of severity and disability, alongside nuanced attributes like pain characterization, duration, and patient expectations.

Background: Neuropathic pain (NP) is a prevalent chronic condition frequently accompanied by adverse emotional states. Previous research has demonstrated the clinical efficacy of electroacupuncture (EA) in mitigating neuropathic pain and its associated mood disorders. Recent studies have underscored a correlation between gut microbiota and both NP and negative emotional states.
