Convolutional Neural Network Models for Visual Classification of Pressure Ulcer Stages: Cross-Sectional Study

Convolutional Neural Network Models for Visual Classification of Pressure Ulcer Stages: Cross-Sectional Study

Pressure injuries (PIs), also known as pressure ulcers, are prevalent in health care settings and result from sustained pressure or shear forces on bony prominences and soft tissues [1]. A meta-analysis encompassing 2,579,049 hospitalized adult patients revealed a 12.8% prevalence of PIs, and the estimated annual total cost of managing PIs increased approximately several times even in high-income countries [2,3].

Effects of Real-Time Pressure Map Feedback on Confidence in Pressure Management in Wheelchair Users With Spinal Cord Injury: Pilot Intervention Study

Effects of Real-Time Pressure Map Feedback on Confidence in Pressure Management in Wheelchair Users With Spinal Cord Injury: Pilot Intervention Study

In response to this, we have developed a mobile pressure mapping app (m PMAP) [12-14] that provides real-time pressure map display on a smartphone screen via wireless connection to the commercially available 4-way stretch Bodi Trac pressure mat (Vista Medical, Inc; Figure 1).

Implantation of an Innovative Intracardiac Microcomputer System for Web-Based Real-Time Monitoring of Heart Failure: Usability and Patients’ Attitudes

Implantation of an Innovative Intracardiac Microcomputer System for Web-Based Real-Time Monitoring of Heart Failure: Usability and Patients’ Attitudes

The pressure inside the left atrium accurately reflects the changes in pressure within the left ventricle and can therefore be used to monitor cardiac function changes during the different phases of HF. The V-LAP system is a miniaturized sensor that is implanted completely percutaneously (ie, without incision) from the femoral vein (groin) and is anchored across the interatrial septum with the sensor portion protruding into the left atrium (Figure 1).

Isolating SARS-CoV-2 Strains From Countries in the Same Meridian: Genome Evolutionary Analysis

Isolating SARS-CoV-2 Strains From Countries in the Same Meridian: Genome Evolutionary Analysis

The aim of this study was to compare the set of SARS-Co V-2 genomes of viral strains isolated from representative countries in the same meridian (longitude), namely, Italy, Sweden, and Congo, which have different climate conditions, to reveal similarities or differences in the patterns of possible evolutionary pressure signatures in their genomes.

Ascertaining the Value of Noninvasive Measures Obtained Using Color Duplex Ultrasound and Central Aortic Pressure Monitoring During the Management of Cerebral Arteriovenous Malformation Resection: Protocol for a Prospective, Case Control Pilot Study

Ascertaining the Value of Noninvasive Measures Obtained Using Color Duplex Ultrasound and Central Aortic Pressure Monitoring During the Management of Cerebral Arteriovenous Malformation Resection: Protocol for a Prospective, Case Control Pilot Study

Before the vasculature returns to normal, the velocity in the former large arteries and veins is markedly reduced concurrent with an elevation of arterial pressure, which is associated with a number of potentially serious postoperative complications, such as arterial-capillary-venous hypertensive (ACVH) syndromes including hemorrhage, edema and vasospasm [10]. In our institution, by rigorously controlling blood pressure, postoperative hemorrhage has reduced from 4.4% to 1% [11].
