The performance of an ultrasound sphygmomanometer (Arteriosonde 1217) has been compared with that of the London School of Hygiene and Tropical Medicine and Hawksley sphygmomanometers. The Arteriosonde gave closely similar values of systolic blood pressure of the other instruments but diastolic blood pressure lay midway between phase 4 and phase 5 of the Korotkoff sounds. Observers using the Arteriosonde showed a significant preference for even terminal digits.

Ejection fraction is commonly used to assess Duchenne muscular dystrophy-associated cardiomyopathy (DMDAC), but it may remain normal (wrongly) despite significant myocardial dysfunction in patients. Therefore, better indicators of myocardial dysfunction are needed for longitudinal (with time) assessment and treatment of DMDAC patients. This study evaluates non-invasive LV PV loop-derived elastance, contractility and efficiency in relation to EF for patients developing DMDAC.

Objective: The aim of this present investigation was to compare changes in transverse abdominis (TrA) thickness in a functional position with those in a less functional but more supportive posture and to determine which posture showed greater changes in TrA thickness between rest and during abdominal drawing-in maneuver (ADIM) relative to external oblique (EO) and internal oblique (IO) muscles.
Methods: Thirty adult participants with chronic low back pain were included in this observational study. The abdominal muscle thickness was measured in the supine, crook lying, prone, quadruped, sitting, side bridge, and standing poitions on a tilt board using ultrasonography.

Background: Ultrasound guidance is commonly used for accessing difficult peripheral veins. For successful access, a tourniquet is required for venodilation. Tourniquets decrease the compressibility and increase the diameter of veins; they also obfuscate artery-vein differentiation on ultrasound.

Options for the continuous and non-invasive monitoring of blood pressure are limited. Cuff-based sphygmomanometers are widely available, yet provide only discrete measurements. The clinical gold-standard approach for the continuous monitoring of blood pressure requires an arterial line, which is too invasive for routine use.

Background: Peripheral arterial disease (PAD) of the lower limbs is caused by atherosclerotic occlusive disease in which narrowing of arteries reduces blood flow to the lower limbs. PAD is common; it is estimated to affect 236 million individuals worldwide. Advanced age, smoking, hypertension, diabetes and concomitant cardiovascular disease are common factors associated with increased risk of PAD.
