The gold standard for blood pressure measurement in pigs is direct monitoring of arterial pressure, but this is an invasive technique adding complexity to surgical procedures. We sought to compare direct measurements obtained via catheterization to more easily-obtained indirect measurements using a sphygmomanometer with an automated cuff. Simultaneous measurements via ...

BACKGROUND: Masked hypertension has been associated with obesity. However, because most studies do not mention the specific cuff size used for home measurements, masked hypertension prevalence may have been overestimated in obese patients because of undersized cuffs. In this prospective, observational study, the effect of miscuffing on hypertension status was ...

The size of nanocrystals provides a limitation on dislocation activity and associated stress-induced deformation. Dislocation-mediated plastic deformation is expected to become inactive below a critical particle size, which has been proposed to be between 10 and 30 nanometers according to computer simulations and transmission electron microscopy analysis. However, deformation experiments ...

Theoretically the auscultatory method using Korotkoff sounds is more related to the maximum artery closure status, while the oscillometric method is more related to the overall artery closure status under the cuff. Therefore, the latter is less accurate than the former. This work introduces a new method, which is more ...

Dense metastable phases obtained under "hard" high-pressure conditions may contain instabilities such as unusual oxidation states or coordination environments that may be partially relieved by "soft" low-temperature chemistry. The synthesis of SrCrO(2.8) and SrCrO(2.75) (right) phases from the high-pressure perovskite SrCrO(3) leads to a relaxation of the coordination around Cr(4+) ...

BACKGROUND: Total shoulder arthroplasty (TSA) is commonly performed for arthritic conditions of the shoulder. The outcome after TSA is generally good, but there are several modes of failure, with one of the more common reasons being glenoid loosening. One possible cause for glenoid loosening is inadequate cementation technique. The purpose ...

Supine hypertension is a common finding in autonomic failure that can worsen orthostatic hypotension and predispose to end-organ damage. This review focuses on nonpharmacologic and pharmacologic approaches to manage hypertension in these patients in the face of disabling orthostatic hypotension. The hypertension of autonomic failure can be driven by sympathetic-dependent ...

Pulmonary hypertension (PH) has diverse causes with heterogeneous physiology compelling distinct management. Differentiating patients with primarily elevated pulmonary vascular resistance (PVR) from those with PH predominantly because of elevated left-sided filling pressure is critical. We reviewed hemodynamics, echocardiography, and clinical data for 108 patients seen at a referral PH clinic ...

BACKGROUND:: Physiologic instability is a common clinical problem in the critically ill. Many natural feedback systems are nonlinear, and seemingly random fluctuations may result from the amplification of external perturbations or even arise de novo as a consequence of their underlying dynamics. Characterization of the underlying nonlinear state may be ...

Epidemiological studies suggest an association between chronic blood pressure (BP) changes and Alzheimer's disease (AD). In particular, there is growing evidence that hypertensive people that do not have their BP adequately treated and controlled in midlife are more likely to develop AD in late-life. It has been hypothesized that cerebrovascular ...

Thiazide and thiazide-like diuretics have been widely used as blood pressure-lowering agents for more than 5 decades. However, their use in patients with advanced chronic kidney disease has been limited and often discouraged. The exact mechanism of how thiazide and thiazide-like diuretics lower blood pressures is still in question. Emerging ...
