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

Ay et al [24] used the European Pressure Ulcer Advisory Panel staging system and included PIs from stage 1 to stage 4. They trained 1091 images from a public dataset of PIs called the PIID (Public Injury Images Dataset) and 15 images from Google via Dense Net121, Inception V3, Mobile Net V2, Res Net152, Res Net50, and VGG16. The results indicated that the average accuracy of the 6 algorithms for each stage during pretraining ranged from 54.84% to 77.42% [24].

Remote Foot Temperature Monitoring Among Veterans: Large Observational Study of Noncompliance and Its Correlates

Remote Foot Temperature Monitoring Among Veterans: Large Observational Study of Noncompliance and Its Correlates

Nearly two-thirds of patients have a recurrence within 5 years of ulcer healing [4]. Loss of pain sensitivity, foot deformity, and peripheral artery disease place individuals at high initial and subsequent risk of ulceration; these conditions do not resolve after healing. Five systematic reviews and meta-analyses [5-9] have been conducted that each included the same 4 or 5 [10-14] randomized controlled trials of foot temperature monitoring.

Pressure Ulcer Management Virtual Reality Simulation (PU-VRSim) for Novice Nurses: Mixed Methods Study

Pressure Ulcer Management Virtual Reality Simulation (PU-VRSim) for Novice Nurses: Mixed Methods Study

The Pieper–Zulkowski pressure ulcer knowledge test (PZ-PUKT), a PU knowledge tool developed by Pieper and Zulkowski [25] and modified and supplemented by Park [26], was used in this study. The PZ-PUKT comprises 39 questions, including 19, 9, and 11 questions on PU stage confirmation, wound assessment, and dressing methods, respectively. Each question was answered “yes,” “no,” or “don’t know,” with 1 point for correct answers and 0 points for incorrect answers.

Patient-Centered Chronic Wound Care Mobile Apps: Systematic Identification, Analysis, and Assessment

Patient-Centered Chronic Wound Care Mobile Apps: Systematic Identification, Analysis, and Assessment

The search terms used were “wound,” “pressure ulcer,” “ulcus,” “Wunde,” “Wunddokumentation,” and “wound documentation.” Two independent reviewers searched each app store. The inclusion criteria were that apps had to (1) be available in both app stores, (2) be available in English or German, and (3) be specifically designed for patients. Apps that were not available free of charge and apps that contained advertisements were excluded.

From the Cochrane Library: Foam Surfaces for Preventing Pressure Ulcers

From the Cochrane Library: Foam Surfaces for Preventing Pressure Ulcers

As an essential component of the total body skin exam, dermatologists should recognize early signs of pressure ulcer development [1] and provide evidence-based preventive measures for patients who are at high risk. Pressure (decubitus) ulcers are common injuries to the skin and underlying soft tissue, resulting from prolonged pressure or shear force. Severe pressure ulcers may deepen, causing localized damage to muscles, tendons, and bones.

Utilization of a Smart Sock for the Remote Monitoring of Patients With Peripheral Neuropathy: Cross-sectional Study of a Real-world Registry

Utilization of a Smart Sock for the Remote Monitoring of Patients With Peripheral Neuropathy: Cross-sectional Study of a Real-world Registry

A number of novel RPM technologies have been developed to provide patients and clinicians with options for monitoring temperature, as temperature is a physiological indicator of inflammation and possibly an early warning sign of foot ulcer formation [4-6]. However, these RPM technologies’ promise for preventing foot ulcers is based on patients’ ability and willingness to use such devices in their activities of daily living.

Computer-Aided Diagnosis of Gastrointestinal Ulcer and Hemorrhage Using Wireless Capsule Endoscopy: Systematic Review and Diagnostic Test Accuracy Meta-analysis

Computer-Aided Diagnosis of Gastrointestinal Ulcer and Hemorrhage Using Wireless Capsule Endoscopy: Systematic Review and Diagnostic Test Accuracy Meta-analysis

The authors established searching formulae using keywords related to the performance of CAD models in the detection of ulcer or hemorrhage using WCE images. Medical Subject Headings (Me SH) terminology keywords were used for the establishment of searching formulae (Textbox 1). 1. CAD of gastrointestinal ulcers in WCE Database: MEDLINE (through Pub Med) #1.

Mobile Health–Based Thermometer for Monitoring Wound Healing After Endovascular Therapy in Patients With Chronic Foot Ulcer: Prospective Cohort Study

Mobile Health–Based Thermometer for Monitoring Wound Healing After Endovascular Therapy in Patients With Chronic Foot Ulcer: Prospective Cohort Study

Between July 2019 and December 2019, a total of 213 patients who had a chronic foot ulcer for longer than 3 months signed informed consent forms and were screened for enrollment (Figure 2). Of these, 15 patients were excluded for clinical signs of wound infection, and 19 patients were excluded due to Rutherford stage VI ischemia.
