The basic pathophysiology of epilepsy is still not fully understood. Epidemiological evidence for epilepsy seems to suggest that it may not only be the propensity for seizures to occur. The high prevalence of comorbidity and the finding that premature mortality is still increased in those who are in long-term remission, suggest that there is a systemic component to the condition. This systemic component is an additional shared risk factor that can explain an important proportion of the comorbidities of epilepsy as well as how an individual with inactive epilepsy remains at an elevated risk of premature mortality. This systemic component can be viewed from the perspective of a number of fundamental pathophysiological processes: inflammation, oxidative stress, glycation, and methylation capacity. These processes are associated with all-cause mortality and there is also a growing understanding of their impact on seizure processes. We propose that epilepsy be considered as the sum of seizures and comorbidities caused by systemic dysfunction, and that the comprehensive management of epilepsy should also include the management of the systemic dysfunction.

Association of systemic inflammatory markers with white matter hyperintensities and microstructural injury: an analysis of UK Biobank data.

J Psychiatry Neurosci

January 2025

From the Department of Neurology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China (Qiao, Zhao, Cong, Y. Li, Tian, Yang, Cao, Su); the School of Electrical and Information Engineering, Zhengzhou University of Light Industry, Zhengzhou, China (Zhu); the Department of Medical Imaging, Henan Provincial People's Hospital & Zhengzhou University People's Hospital, Zhengzhou, China (P. Li).

Background: White matter damage is closely associated with cognitive and psychiatric symptoms and is prevalent in cerebral small vessel disease (CSVD); although the pathophysiological mechanisms involved in CSVD remain elusive, inflammation plays a crucial role. We sought to investigate the relationship between systemic inflammation markers and imaging markers of CVSD, namely white matter hyperintensity (WMH) and microstructural injury.

Methods: We conducted a study involving both cross-sectional and longitudinal data from the UK Biobank Cohort.

Claudins as diagnostic tools and therapeutic targets-Glimpse of the horizon.

Cancer Treat Rev

January 2025

Gastrointestinal Unit, Department of Medicine, Royal Marsden Hospital, London and Surrey, UK. Electronic address:

Claudins (CLDNs) play a crucial and indispensable role as fundamental components within the structure of tight junctions. Due to the distinct and unique distribution pattern exhibited by CLDNs in both normal and malignant tissues, these proteins have garnered significant attention as pivotal targets for systemic anti-cancer therapy and as noteworthy diagnostic markers. This review provides a comprehensive and detailed elucidation of the fundamental understanding surrounding CLDNs, their intricate expression patterns, the potential role they play in cancer diagnosis and therapeutic potentials; all encapsulated within a succinct summary of the cutting-edge advancements and the information derived from various clinical trials.

Background: Caffeic acid phenethyl ester (CAPE), an active component of honey bee propolis, has been demonstrated in animal models and studies to have anti-inflammatory, antioxidant, immunomodulatory, neuroprotective, and cytoprotective properties.

Objective: We investigated the efficacy of CAPE, which we believe may be therapeutically useful in facial nerve restoration due to its neuroprotective and antioxidant properties.

Material And Methods: 20 Sprague Dawley rats were divided randomly into 4 primary and 2 secondary groups and assigned as control, methylprednisolone, CAPE, CAPE+methylprednisolone groups and the sham and the trauma groups.

Toll-Like Receptors (TLRs) is a pattern recognition receptor that connects innate and adaptive immunity and participates in inflammatory responses play a key role in common autoimmune diseases such as Rheumatoid Arthritis (RA), systemic lupus erythematosus (SLE), psoriasis, and Sjögren's syndrome (SS) by participating in antigen recognition, immune cell activation, and inflammatory factor release. Due to the multi-component and multi-target characteristics of traditional Chinese medicine (TCM), the role of TCM active ingredients acting on TLRs has been widely studied. This article describes the relationship between TLR and four autoimmune diseases, as well as a review of the efficacy of TLR intervention by active ingredients of traditional Chinese medicine.

Indigenous communities worldwide continue to disproportionately bear the burden during pandemics due to ongoing health inequities and systemic exclusion from pandemic decision-making processes. As the global community prepares for the next pandemic, it is critical to prioritise Indigenous leadership and governance within public health responses. This commentary highlights successful models of Indigenous-led pandemic responses during COVID-19 in Canada and Australia.
