Chronic venous insufficiency and varicose veins occur commonly in affluent countries and are a socioeconomic burden. However, there remains a relative lack of knowledge about venous pathophysiology. Various theories have been suggested, yet the molecular sequence of events is poorly understood. Transforming growth factor-beta one (TGF-β1) is a highly complex polypeptide with multifunctional properties that has an active role during embryonic development, in adult organ physiology and in the pathophysiology of major diseases, including cancer and various autoimmune, fibrotic and cardiovascular diseases. Therefore, an emphasis on understanding its signaling pathways (and possible disruptions) will be an essential requirement for a better comprehension and management of specific diseases. This review aims at shedding more light on venous pathophysiology by describing the TGF-β1 structure, function, activation and signaling, and providing an overview of how this growth factor and disturbances in its signaling pathway may contribute to specific pathological processes concerning the vessel wall which, in turn, may have a role in chronic venous insufficiency.

Background: Complex craniofacial trauma is defined as those traumatic injuries that are not responding to initial treatment and may involve chronic infection, tissue exposure, and soft tissue contusions. Typical reconstruction using a Y-shaped microvascular venous anastomotic free flap is labor intensive. Although free flap grafts have been used in many applications, their use for combined microvascular anastomotic therapy remains an unexplored but attractive possibility.

Background: Although conventional pre-operative venography can accurately delineate venous anatomy as an alternative to ultrasound for hemodialysis access planning, it may carry a risk of contrast-induced acute kidney injury (AKI) and progression of renal failure in chronic kidney disease (CKD) patients not yet on dialysis. Therefore, the objective of this study was to evaluate the safety and efficacy of pre-operative venograms in pre-end-stage kidney disease (ESKD) patients.
Methods: We performed a retrospective cohort study (2018-2022) of consecutive pre-ESKD patients who underwent staged bilateral venograms for preoperative vein mapping prior to hemodialysis access creation at a tertiary care medical center.

Chronic kidney disease (CKD) is a global health concern, with a 10% global prevalence. Its prevalence may further increase in the coming decades, thereby increasing the risk of uremic xerosis. Approximately 50-90% of patients with CKD have xerosis, leading to pruritus that affects their quality of life due to sleep disturbances, anxiety, and depression.

Background: Limited data exist regarding the safety of direct oral anticoagulants in hemodialysis patients with venous thromboembolic disease. This study aims to investigate the safety of direct oral anticoagulants in hemodialysis patients using national data.
Methods: The National Health Insurance Service database was retrospectively queried to identify chronic kidney disease patients who took direct oral anticoagulants for venous thromboembolism from 2008 to 2019.

Sterile inflammation contributes to the development of many liver diseases including non-alcoholic fatty liver disease. Tumor necrosis factor alpha (TNFα) is a key cytokine driving liver inflammation primarily through pro-inflammatory activation of liver sinusoidal endothelial cells (LSEC). The knowledge of whether modulating LSEC activation can alleviate liver inflammation is scarce.
