Atrial fibrillation (AF) is the most common type of cardiac arrhythmia. To date, a lot of research has been conducted to investigate the underlying mechanisms of this disease at both molecular and cellular levels. There is increasing evidence suggesting that autoimmunity is an important factor in the initiation and perpetuation of AF. Autoantibodies are thought to play a pivotal role in the regulation of heart rhythm and the conduction system and, therefore, are associated with AF development. In this review, we have summarized current knowledge concerning the role of autoantibodies in AF development as well as their prognostic and predictive value in this disease. The establishment of the autoantibody profile of separate AF patient groups may appear to be crucial in terms of developing novel treatment approaches for those patients; however, the exact role of various autoantibodies in AF is still a matter of ongoing debate.

Background/Objectives: Facial discoid dermatosis is a rare inflammatory dermatosis presenting with round, superficial erythematous lesions located on the face. Diagnosis may be challenging and often requires careful clinicopathological correlation due to overlapping clinical and histopathological features. Skin lesions are typically resistant to a wide range of topical and systemic treatments. From the perspective of personalized medicine, improved phenotyping of rare inflammatory dermatoses may support more precise diagnosis, individualized therapeutic decisions, and non-invasive disease monitoring. This study aimed to characterize facial discoid dermatosis using line-field confocal optical coherence tomography and reflectance confocal microscopy and to discuss its differential diagnosis and therapeutic implications. Methods: We report a case of facial discoid dermatosis in a 35-year-old patient examined with line-field confocal optical coherence tomography and reflectance confocal microscopy. The imaging findings were interpreted in correlation with clinical and histopathological features. A literature review was performed to summarize differential diagnoses, therapeutic perspectives, and the proposed relationship between facial discoid dermatosis and pityriasis rubra pilaris. Results: Non-invasive imaging revealed morphological features consistent with a psoriasiform inflammatory dermatosis and provided additional in vivo information supporting the diagnosis. The literature review showed limited evidence for a direct association between facial discoid dermatosis and pityriasis rubra pilaris, with only isolated reports suggesting possible overlap or progression. Conclusions: Facial discoid dermatosis appears to represent a distinct psoriasiform dermatosis. Line-field confocal optical coherence tomography and reflectance confocal microscopy may contribute to a personalized diagnostic approach by supporting differential diagnosis and potentially guiding individualized monitoring in rare inflammatory facial dermatoses.

Introduction The gut microbiota, a complex community of microorganisms residing in the human gastrointestinal tract, is integral to various bodily functions. Understanding the role of gut microbiota is essential due to its significant influence on human health and disease. Current research indicates that gut microbiota can modulate immune responses and maintain homeostasis. Despite extensive studies, the specific mechanisms by which gut microbiota influences chronic inflammatory diseases remain unclear. Investigating the interaction between gut microbiota and the immune system can provide new insights into potential therapeutic strategies for chronic inflammatory diseases. Aim of the study This study aims to elucidate the mechanisms by which gut microbiota affects immune responses, particularly in chronic inflammatory conditions. We hypothesize that alterations in gut microbiota composition can significantly modulate immune responses, thereby influencing the progression of chronic inflammatory diseases. Conclusions We discuss potential therapeutic interventions targeting the gut microbiota for chronic inflammatory diseases that encompass several approaches. These include the administration of probiotics and prebiotics, fecal microbiota transplantation (FMT), diverse dietary modifications. Personalized microbiome-based therapies offer tailored interventions that combine various methodologies. Further scientific investigation is necessary to comprehensively elucidate and optimize these therapeutic strategies.

Osteoarthritis (OA) is a prevalent degenerative joint disease that significantly impacts the quality of life of millions worldwide, particularly the elderly. While conventional non-surgical treatments, such as NSAIDs, intra-articular injections, and physical therapy, provide symptomatic relief, their long-term efficacy and safety remain limited. Recent advancements in understanding OA pathophysiology have spurred the development of innovative therapeutic strategies targeting disease progression. This review examines emerging pharmacological and regenerative approaches, including disease-modifying osteoarthritis drugs (DMOADs), biologics, and cell-based therapies. Cutting-edge technologies such as RNA interference, CRISPR/Cas9, and advanced regenerative medicine are also explored for their potential to revolutionize OA management. Additionally, the integration of novel therapies with traditional interventions is discussed, highlighting opportunities for a more personalized, multimodal approach to OA care. Despite significant progress, challenges such as translational hurdles, cost barriers, and long-term efficacy require further investigation. This review emphasizes the transformative potential of emerging therapies in addressing the unmet needs of OA patients and shaping future treatment paradigms.
