A novel skin temperature estimation system for predicting pressure injury occurrence based on continuous body sensor data: A pilot study.

Background: Pressure injury prevention is important in older patients with immobility. This requires an accurate and efficient prediction of the development of pressure injuries. We aimed to develop a method for estimating skin temperature changes due to ischemia and inflammation using temperature sensors placed under bedsheets to provide an objective, non-invasive, and non-constrained risk assessment tool.

Gait due to difference in Intravenous pole position on the healthy participants.

Introduction: The gait while using an intravenous (IV) pole is close to the gait of the elderly and fallers. Additionally, one survey has reported that the diagonal position is optimal for transporting an IV pole with a light load. However, in clinical practice, carrying a heavier load may be possible.

Preparation of Perfluorosulfonated Ionomer Nanofibers by Solution Blow Spinning.

In this work, we report the preparation of high-purity perfluorosulfonated ionomer (Nafion) nanofibers (NFs) via solution blow spinning (SBS). Fiber formation in solution jet spinning is strongly dependent on the structure of the spinning solution. Upon adding a small amount of poly(ethyleneoxide) (PEO) as a spinning aid to Nafion dispersion, most of the highly ordered Nafion aggregate disappeared, allowing the stable production of bead-free and smooth high-purity NFs (Nafion/PEO = 99/1) by SBS.

Development of Water-Insoluble Vehicle Comprising Natural Cyclodextrin-Vitamin E Complex.

Development of a novel antioxidant-delivery vehicle exerting biosafety has been attracting a great deal of interest. In this study, a vehicle comprising a natural composite consisting of vitamin E (α-tocopherol; Toc) and cyclodextrin (CD) additives was developed, directed toward aqua-related biological applications. Not only -CD, but also -CD, tended to form a water-insoluble aggregate with Toc in aqueous media.

Influence of advanced pulmonary vascular remodeling on accuracy of echocardiographic parameters of left ventricular filling pressure.

Evaluation of left ventricular filling pressure plays an important role in the clinical management of pulmonary hypertension. However, the accuracy of echocardiographic parameters for the determination of left ventricular filling pressure in the presence of pulmonary vascular lesions has not been fully addressed. We retrospectively investigated 124 patients with pulmonary hypertension due to pulmonary vascular lesions (noncardiac pulmonary hypertension group) and 113 patients with ischemic heart disease (control group) who underwent right heart catheterization and echocardiography.
