Cardiovascular event rates are markedly increased in rheumatoid arthritis (RA), and RA atherogenesis remains poorly understood. The relative contributions of traditional and nontraditional risk factors to cardiovascular disease in RA await elucidation. The present study comprises three components. First, we compared biomarkers of endothelial dysfunction (vascular cell adhesion molecule [VCAM]-1, intercellular adhesion molecule [ICAM]-1 and endothelial leucocyte adhesion molecule [ELAM]-1) in 74 RA patients and 80 healthy control individuals before and after controlling for traditional and nontraditional cardiovascular risk factors, including high-sensitivity C-reactive protein (hs-CRP), IL-1, IL-6 and tumor necrosis factor-alpha. Second, we investigated the potential role of an extensive range of patient characteristics in endothelial dysfunction in the 74 RA patients. Finally, we assessed associations between biomarkers of endothelial dysfunction and ultrasonographically determined common carotid artery intima-media thickness and plaque in RA. The three biomarkers of endothelial dysfunction, as well as hs-CRP, IL-1, IL-6 and tumor necrosis factor-alpha, were higher in patients than in control individuals (P < 0.0001). Patients were also older, exercised less and had a greater waist circumference, blood pressure and triglyceride levels (P

Preservation of Vascular Endothelial Function in Late-Onset Postmenopausal Women.

Background: Postmenopausal women (PMW) who complete menopause at a late age (55+ years) have lower cardiovascular disease risk than PMW who complete menopause at a normal age (45-54 years). However, the influence of late-onset menopause on vascular endothelial dysfunction is unknown. Moreover, the mechanisms by which a later age at menopause may modulate endothelial function remain to be determined.

A 75-year-old woman with a history of systemic lupus erythematosus (SLE) presented with isolate ocular symptoms, including a left scleral hematoma, elevated erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). Initial evaluation combined with isolated ocular symptoms raised concerns for giant cell arteritis rather than an SLE flare. Thus, prompt initiation of high-dose intravenous methylprednisolone (250 mg every six hours) was warranted.

Implantable hemodynamic devices like the CardioMEMS HF System are commonly used to manage fluid status in patients with heart failure (HF) by measuring pulmonary pressures. Although CardioMEMS has been shown to reduce HF hospitalizations, rare complications (eg, device endothelialization) can occur and warrant clinical attention. A 67-year-old woman with HF with preserved ejection fraction and group 2 pulmonary hypertension experienced recurrent HF exacerbations.

Background: as we look to extend lung perfusion times (EVLP) to improve preservation, the metabolic activity of the lungs will require support from other organ functions. Active functional liver support, including detoxification, synthesis, and regulation, can improve lung preservation during EVLP. This study aimed to demonstrate the effects of hepatic conditioning of the EVLP perfusate on lung endothelium, via the receptor of advanced glycation end-products (RAGE)-nuclear-factor-κB (NF-κB) signaling in vitro.

Background: Descemet's membrane endothelial keratoplasty (DMEK) is a highly effective procedure for corneal endothelial dysfunction; however, once a DMEK graft is deployed, repositioning can be challenging. Therefore, this study aimed to evaluate the efficacy of a technique that utilizes infusion and small air bubbles to reposition a misaligned deployed graft.
Methods: This retrospective interventional case series enrolled patients who underwent DMEK between January 2022 and July 2023, including cases where the DMEK graft was attached and unfolded in off-center positions".
