We recently found that renal carbonic anhydrase (CA) is involved in the reabsorption of inorganic nitrite (NO2 - ), an abundant reservoir of nitric oxide (NO) in tissues and cells. Impaired NO synthesis in the endothelium and decreased NO bioavailability in the circulation are considered major contributors to the development and progression of renal and cardiovascular diseases in different conditions including diabetes. Isolated human and bovine erythrocytic CAII and CAIV can convert nitrite to nitrous acid (HONO) and its anhydride N2 O3 which, in the presence of thiols (RSH), are further converted to S-nitrosothiols (RSNO) and NO...

Mean platelet volume (MPV) was recently published as a possible marker of coronary artery disease in patients at high risk for major adverse cardiac events. Because platelets play an important role in atherosclerosis, we examined the relationship between critical limb ischemia (CLI) and MPV in patients with peripheral arterial occlusive disease (PAOD). Our study comprised 2124 PAOD patients. Univariate logistic regression was performed to analyze potential predictors for CLI. Nagelkerke's R² is reported. Cross validation was performed using the leave-one-out principle...

Despite advances, challenges remain for less invasive imaging of peripheral arterial occlusive disease (PAOD) using computed tomography (CT) angiography. The application of dual-energy imaging to PAOD has been reported to improve the diagnostic accuracy of this application; however, severe arteriosclerosis with heavy arterial wall calcification still hampers definitive lesion characterisation, especially in distal and smaller arteries. Recently an ultra-high resolution scanner has been introduced. In combination with advances in post-processing, such as subtraction techniques, these developments may overcome some of the current challenges and allow far more detailed characterisation of PAOD non-invasively...

The ankle-brachial index (ABI) is a reliable diagnostic examination for peripheral arterial occlusive disease (PAOD). We previously reported CHADS2 score was significantly correlated with PAOD. However, the association between CHA2 DS2 -VASc score and ABI < 0.9 is not evaluated in the literature. The aim of the present study was to investigate whether CHA2 DS2 -VASc score has a strong association with PAOD. We enrolled 1482 patients in this study. PAOD was defined as ABI < 0.9 in either leg. Vascular disease in CHA2 DS2 -VASc score was modified as vascular disease except PAOD...

BACKGROUND: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects...

Painless aortic dissection (PAoD) has been previously linked to poor outcomes. We recently encountered a case of a patient with PAoD presenting with dyspnea; the clue to diagnosis was the presence of a loud aortic diastolic murmur. A systematic review of the literature revealed 86 other cases, 62% of which occurred in men with a mean age of 65 years. Left-sided neurologic deficits were the most common presentation, followed by dyspnea and bilateral lower extremity deficits. Pulse asymmetry was found in 53% of patients, as 29% had right-left asymmetry and 24% had upper-lower asymmetry...

BACKGROUND: Community Paramedicine (CP) is a rapidly evolving field within prehospital care where paramedics step outside of their traditional roles of treating acute conditions to provide elements of primary and preventive care. It is unclear if current state oversight regarding the scope of practice (SOP) for paramedics provides clear guidance on the novel functions provided and skills performed by CP programs. OBJECTIVE: To determine the process and authority, as currently defined by state laws and regulations in the United States, to expand paramedic SOP in order to perform CP roles and to assess state EMS agencies' interpretation of paramedic SOP as it applies to CP...

BACKGROUND: The blood concentrations of total cholesterol and low-density lipoprotein (LDL) do not predict survival in patients older than 60 years. The atherogenic index of plasma (AIP) is a logarithm of the triacylglycerol to high-density lipoprotein (HDL) ratio and a surrogate for the concentration of small dense LDL. It might be a better reflection of the risk of all-cause death in elderly patients. METHODS: We conducted a prospective observational study of patients with arterial hypertension older than 60 years...
