Abstract Blood pressure is an important physiological parameter to reflect human vital signs. In order to achieve the non-contact dynamic blood pressure acquisition based on ordinary optical camera, a theoretical understanding of the functional relationship between blood pressure and pulse wave signal conduction time. And through imaging photoelectric plethysmography (IPPG), pulse wave signal conduction time of forehead and hand was obtained with ordinary optical camera. First, the pulse wave conduction time was obtained by recording the video with an ordinary optical camera. Second, real-time blood pressure values were collected. Finally, based on the relationship between blood… More >

Abstract Aim: To determine the profiles of clinical features including four-limb blood pressure (BP), saturations of peripheral oxygen (SpO₂), and echocardiographic features in infants with coarctation of aorta (CoA) to facilitate congenital heart diseases screening. Methods: The charts of infants with CoA were retrospectively reviewed. All in-hospital infants suspected of congenital heart diseases by clinical teams were prospectively measured of four limbs BPs and SpO₂ in a regional cardiac transferring center during 2013 and 2019. Echocardiography as a gold standard test was followed within 2 days after suspicion. All infants were divided into non-significant CoA group or significant… More >

Abstract Objective: The most accurate noninvasive parameter to predict whether a patient with aortic coarctation will meet interventional criteria at catheterization remains elusive. We aim to determine the best independent echocardiographic predictors of a coarctation peak‐to‐peak pressure gradient ≥20 mm Hg at catheterization, the ac‐ cepted threshold for intervention.
Design: Retrospective query of our catheterization database from 1/2007 to 7/2016 for the diagnostic code of aortic coarctation was performed. Multiple echocardio‐ graphic measurements and blood pressure gradients prior to cardiac catheterization were collected. Univariate correlation of variables with the continuous catheteriza‐ tion peak were calculated using Spearman’s rho.… More >

Abstract Background: Recognition of high blood pressure (BP) in children is poor, partly due to the need to compute age-sex-height referenced percentiles. This study examined the change in abnormal BP recognition before versus after the introduction of an electronic health record (EHR) app designed to calculate BP percentiles with a training lecture.
Methods and results: Clinical data were extracted on all ambulatory, non-urgent encounters for children 3–18 years old seen in primary care, endocrinology, cardiology, or nephrology clinics at an urban, academic hospital in the year before and the year after app introduction. Outpatients with at least 1… More >

Abstract Objectives: Radiofrequency ablation (RFA) is a minimally invasive therapy aimed at maximal preservation of renal function in the nonsurgical renal mass patient. We evaluate our experience with RFA of renal tumors in the solitary kidney.
Patients and methods: A retrospective review of all patients with a solitary kidney treated with RFA for renal mass was performed. Two radiologists reviewed all images. From December 2001 to June 2006, 55 renal tumors were treated with RFA in 30 patients with a solitary kidney. Percutaneous approach was used in 44 tumors (26 patients) and intraoperative open approach in 11 tumors… More >

Abstract Introduction. High-normal blood pressure (HNBP) seems to be related to increased cardiovascular risk in healthy, normotensive subjects, while essential hypertension is associated with an increase in extracellular matrix content, especially fibrillar collagen type I. The aim of our study was to investigate whether collagen degradation is altered in healthy normotensives with HNBP, and whether this alteration could be related to disturbances in the matrix metalloproteinases plasma concentration, and to compare the findings to those of healthy normotensives with normal blood pressure (NBP) levels, matched for age, sex and BMI. Methods. Twenty six (14 males, 12… More >
