Measurement of morphological and physiological skin properties in aged care residents: a test –retest reliability pilot study

ABSTRACT This test–retest pilot study investigated the intra‐rater reliability and reproducibility of non‐invasive technologies to objectively quantify morphological (colour, thickness and elasticity) and physiological (transepidermal water loss (TEWL), hydration, sebum and pH) skin properties in an aged care population. Three consecutive measurements were taken from five anatomical skin sites, with the mean of each measurement calculated. The intra‐class correlation coefficient (ICC) and the standard error of measurement (SEM) were used to examine the intra‐rater reliability and reproducibility of measurements. Non‐invasive technologies in this study showed almost perfect reliability for ultrasound measurements of the subepidermal low echogenicity band (SLEB) (ρ = 0·95–0·99) and skin thickness (ρ = 0·95–0·99) across all sites. The ICC was substantial to almost perfect for pH (ρ = 0·76–0·88) and viscoelasticity (ρ = 0·67–0·91) across all sites. Hydration (ρ = 0·53–0·85) and skin retraction (ρ = 0·57–0·99) measurements ranged from moderate to almost perfect across all sites. TEWL and elasticity were substantial to almost perfect across four sites. Casual sebum levels and most colour parameters showed poor ICC. The use of non‐invasive t...

Freitas, Igor Guida P.P de Sousa, Pierre M. Esteves, Renata A. SimaoAbstractThe present study reports the formation of thin films from covalent organic framework (COF) via ultrasound using different solvents. The morphology of the resulting films was correlated to the rate of bubble formation and the maximum bubble size, through derivations from the Rayleigh-Plesset equation. Solvents were chosen according to their different characteristics, such as polariz...

ConclusionsWithin a population at risk of fetal macrosomia the performance of 3D-US-EFW is similar to that of 2D-US-EFW in the prediction of macrosomia at term regardless of the method used for the projection of the EFW, however different properties were noted between the two techniques. Such finding suggests a potential complementary role of the techniques which warrants evaluation in future research.

In this study we comparatively investigated the SSC of powdered pomegranate husks by A. niger and Saccharomyces cerevisiae and evaluated the recovery yields of EA by an ultrasound and microwave-assisted 7:3 water/ethanol extraction. Surprisingly enough, the yields obtained by S. cerevisiae fermentation (4% w/w) were found 5-fold higher than those of the A. niger fermented material, with a 10-fold increase with respect to the unfermented material. The EA origin was traced by HPLC analysis that showed a significant decrease in the levels of punicalagin isomers and granatin B and formation of punicalin following fermentation....

PP Batchala, PK RehmJournal of Postgraduate Medicine 2019 65(4):237-240 A 66-year-old female underwent preoperative evaluation for primary hyperparathyroidism. Ultrasound (US) neck and technetium (Tc)-99m-sestamibi planar scintigraphy were negative, but single photon emission computed tomography/computed tomography (SPECT/CT) demonstrated a tracer-avid retropharyngeal nodule compatible with parathyroid adenoma (PTA). A retrospective review of CT neck angiogram (CTA) and neck magnetic resonance imaging (MRI) performed 4 months earlier for stroke evaluation revealed arterial phase hyperenhancing retropharyngeal tissue, whic...

ConclusionsThe current rapid, multi-slice acquisition and real-time implementation of temperature and displacement visualization may be useful in clinical practices. It may help defining operational safety margins, improving therapy precision and efficacy. Simulations were in good agreement with experimental data and may thus be used prior treatment for procedure planning.
