OBJECTIVE: Digital subtraction angiography (DSA) of the peripheral arterial vasculature provides lumenographic information but only a qualitative assessment of blood flow. The ability to quantify adequate tissue perfusion of the lower extremities would enable real-time perfusion assessment during DSA of patients with peripheral arterial disease (PAD). In this study, we used a novel real-time imaging software to delineate tissue perfusion parameters in the foot in PAD patients. METHODS: Between March 2015 and June 2016, patients (N = 31) underwent lower extremity angiography using a two-dimensional perfusion (2DP) imaging protocol (Philips Healthcare, Andover, Mass)...

Acute pulmonary embolism (PE) is the third cause of cardiovascular (CV) mortality. We evaluated a new risk index, named Age-Mean Arterial Pressure Index (AMAPI), to predict 30-day CV mortality in patients with acute PE. Data of 209 patients (44.0% male and 56.0% female, mean age 70.58 ± 14.14 years) with confirmed acute PE were retrospectively analysed. AMAPI was calculated as the ratio between age and mean arterial pressure (MAP), which was defined as [systolic blood pressure + (2 × diastolic blood pressure)]/3...

We report a 14-year-old boy with recurrent episodes of headache caused by uncontrolled hypertension. The diagnosis of renovascular hypertension due to Takaysu arteritis (TA) was made based on an increase in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and computed tomography (CT) image of bilateral renal artery stenosis was taken. Renal scintigraphy revealed normal perfusion and function of the right kidney and severe reduction of the perfusion and function of the left kidney. Careful drug adjustments significantly improved but did not fully control the blood pressure (BP); further, angioplasty, which showed almost occlusion of the left renal artery opening and the minor narrowing of the right renal artery, failed to regain sufficient BP control...

Background: We previously reported that lysophosphatidic acid (LPA) promoted cardiomyocyte hypertrophy in vitro via one of its G protein-coupled receptor subtypes, LPA3. In this study, we examined the role of LPA3 in cardiac hypertrophy induced by isoproterenol (ISO) and myocardial infarction. Methods:In vitro, neonatal rat cardiomyocytes (NRCMs) were subjected to LPA3 knocked-down, or pretreated with a β-adrenergic receptor (β-AR) antagonist (propranolol) before LPA/ISO treatment. Cardiomyocyte size and hypertrophic gene (ANP, BNP) mRNA levels were determined...

OBJECTIVE: This study was intended to demonstrate the feasibility and efficacy of purge parathyroidectomy (PPTX) for patients with secondary hyperparathyroidism (SHPT). METHODS: The "seed, environment, and soil" medical hypothesis was first raised, following review of the literatures, to demonstrate the possible causes of persistence or recurrence of SHPT after parathyroidectomy. Subsequently, the novel surgical strategy of PPTX was proposed, which involves comprehensive resection of the fibro-fatty tissues, including visible or invisible parathyroid, within the region surrounded by the thyroid cartilage, bilateral carotid artery sheath, and the brachiocephalic artery...

There is evidence suggesting that exercise training (ET) acts as a factor toward resistance to Trypanosoma cruzi infection. However, the effects of mean arterial pressure (MAP), heart rate (HR), and nitric oxide (NO) during the acute phase of infection has not been elucidated yet. Swiss mice were randomly assigned into four groups: sedentary control (SC, n = 30), trained control (TC, n = 30), sedentary infected (SI, n = 30), and trained infected (TI, n = 30). ET was performed on the treadmill for 9 weeks. After training, the mice were infected with 5 × 10(3) trypomastigotes of T...

AIM: To clarify the role of neoadjuvant concurrent chemoradiotherapy (NACCRT) followed by surgical resection for localized or locally advanced perihilar cholangiocarcinoma (CCA). METHODS: We retrospectively reviewed 57 patients who underwent surgical resection with or without NACCRT for perihilar CCA; 12 patients received NACCRT and 45 patients did not received NACCRT. Patients with locally advanced perihilar CCA requiring NACCRT were defined as follows: (1) a mass involving unilateral branches of the portal vein or hepatic artery with insufficient volume of the anticipated remnant lobe; or (2) an infiltrating mass in the main portal vein that was too long for reconstruction, identified at preoperative staging...

PURPOSE: Cardiometabolic disease remains a leading cause of morbidity and mortality in developed nations. Consequently, identifying and understanding factors associated with underlying pathophysiological processes leading to chronic cardio metabolic conditions is critical. Metabolic health, arterial elasticity, and insulin sensitivity (SI) may impact disease risk, and may be determined in part by myofiber type. Therefore, the purpose of this study was to test the hypothesis that type I myofiber composition would be associated with high SI, greater arterial elasticity, lower blood pressure, and blood lipids; whereas, type IIx myofibers would be associated with lower SI, lower arterial elasticity, higher blood pressure, blood lipids...

Hypernatremia develops commonly in critically ill patients during hospitalization, and is associated with adverse outcomes. However, community acquired hypernatremia (CAH) has been rarely studied. We conducted a study in patients who presented to an urban referral hospital, and were admitted with CAH. We retrospectively analyzed patients admitted to an urban tertiary care hospital from January 1, 2012 to December 31, 2014. CAH is defined as more than 147 mEq/L at admission in patients not transferred from other hospitals...
