Purpose: There are multiple postexercise recovery technologies available in the market based on the assumption of blood-flow enhancement. Lower-limb intermittent pneumatic compression (IPC) has been widely used, but the available scientific evidence supporting its effectiveness remains scarce, requiring a deeper investigation into its underlying mechanisms. The aim of this study was to assess the hemodynamic effects caused by the use of IPC at rest.
Methods: Twenty-two soccer and track and field athletes underwent two 15-minute IPC protocols (moderate- [80 mm Hg] and high-pressure [200 mm Hg]) in a randomized order. Systolic peak velocity, end-diastolic peak velocity, arterial diameter, and heart rate were measured before, during (at the eighth minute), and 2 minutes after each IPC protocol.
Results: Significant effects were observed between before and during (eighth minute) the IPC protocol for measures of systolic (P < .001) and end-diastolic peak velocities (P < .001), with the greater effects observed during the high-pressure protocol. Moreover, 2 minutes after each IPC protocol, hemodynamic variables returned to values close to baseline. Arterial diameter presented significant differences between pressures during the IPC protocols (P < .05), while heart rate remained unaltered.
Conclusion: IPC effectively enhances transitory blood flow of athletes, particularly when applying high-pressure protocols.

Background: Asymmetric underexpansion of transcatheter heart valves (THVs), as observed on fluoroscopy, may influence prosthesis function or long-term durability of transcatheter aortic valve implantation (TAVI).
Aims: This study aimed to evaluate the effect of stent frame asymmetry on hemodynamic performance and clinical outcomes in ACURATE neo and neo2 THVs.
Methods: In a retrospective registry, the TAVI asymmetry index was defined as the ratio of the THV stent frame diameter.

Among the different forms of hydrotherapy, carbon dioxide (CO) water immersion improves peripheral vasodilation and blood flow compared with tap water immersion; however, the heat stress placed on the body through CO water immersion and the appropriate immersion protocols are uncertain. Therefore, this study aimed to compare the thermoregulatory responses during CO and tap water immersions. The participants were 10 male college baseball players.

Background: The hemodynamic effects of femoro-femoral venoarterial (VA) extracorporeal membrane oxygenation (ECMO) on pulmonary capillary wedge pressure (PCWP) remain poorly defined. High ECMO flow is believed to increase PCWP and the risk of pulmonary edema; yet, supporting in vivo physiological data are lacking.
Objectives: The purpose of this study was to evaluate the impact of incremental femoro-femoral VA-ECMO flow variations on PCWP, hemodynamic, and echocardiographic parameters in patients with cardiogenic shock during the early phase of VA-ECMO support, after stabilization.

Objective: to compare the effect of salt consumption on blood pressure (BP) of an indigenous and of a non-indigenous population in Brazil.
Design: the studies were carried out in the years of 1999-2004 in an urban population of Vitória (n = 1,663), the capital of Espírito Santo State, and in an indigenous population settled in a reserve of Aracruz (n = 663). Salt consumption was evaluated by a 12-hour overnight urine collect.

Reading fluency is a vital building block for developing literacy, yet the best way to practice fluency-reading aloud-can cause anxiety severe enough to inhibit literacy development in ways that can have an adverse effect on students through adulthood. One promising intervention to mitigate oral reading anxiety is to have children read aloud to a robot. Although observations in prior work have suggested that people likely feel more comfortable in the presence of a robot instead of a human, few studies have empirically demonstrated that people feel less anxious performing in front of a robot compared with a human or used objective physiological indicators to identify decreased anxiety.
