Biophysical and Subject-Based Assessment of the Effects of Topical Moisturizer Usage on Xerotic Skin—Part II: Visioscan® VC 20plus Imaging

As new biophysical methods become available to the skin researcher it is important to understand the type of information that they are capable of measuring, and how it relates to consumer perception of topical moisturizing products. The aim of the work presented here was to understand what dry skin imaging can reveal about the skin and subject feedback from the use of a topical moisturizing product and how it relates to the consumer usage experience of a topical product. Images from a dry skin camera—the Visioscan® VC 20plus—during 3 weeks in vivo usage of a topical moisturizing product were analyzed. Subject feedback regarding their skin condition was also collected. Strong statistical improvements (p < 0.05) were observed for a wide range of skin parameters derived from the Visioscan® VC 20plus. Skin scaliness and smoothness and parameters associated with skin health and appearance (surface, energy, contrast, homogeneity) improved as a result of topical product usage. Subjects reported their skin to feel less dry, to be smoother, and more supple and to look and feel healthier after product usage. The length of time until they felt the need to re-apply the product increased during the study

Evaluation of the Use of Blood Products in ICU Hospitalized COVID-19 Patients

(1) Background: The COVID-19 pandemic tested the public health system’s readiness for crises and highlighted the importance of knowing the demand for blood products and the maintenance of the blood supply chain. The aim of this study was to evaluate blood product usage in a series of patients that were hospitalized due to COVID-19 and to analyze their demographics and clinical characteristics. (2) Methods: In this retrospective cohort study, we analyzed data from transfused COVID-19 patients that were treated in the University Hospital Medical Center Bezanijska Kosa in Belgrade, Serbia during the second wave of the epidemic. (3) Results: This study included 90 patients. The median age of the patients was 72 (range 23–95) years. The median time of hospitalization was 23 days (range 3–73 days). In intensive care units (ICUs) the median time of hospitalization was 9 days (range 0–73). One or more comorbidities were observed in 86 individuals (95.6%). The total number of transfused red blood cell concetrates (RBC) was 304 (139 in ICU, 165 in other wards), with a mean of 3 units/patient (range 1–14). Comorbidities, severity of illness and hospital duration in the ICU were statistically significant predictors of higher RBC use. (4) Conclusion: Knowledge of the transfusion profile of COVID-19 patients allowed better management of the hospital’s blood stocks during the COVID-19 pandemic.

Study on Mechanical Properties of Polyester with Addition of Recycle Gift or Members Card

Increasing usage of gift cards will end up increasing the waste. Instead of throwing in the dustbin, re-cycling the cards may help in increasing the product usage and contribute to the environment sustainability. In this study, the re-cycle gift cards were combined with polyester to produce polymer blend. The composition of re-cycle gift cards was 2, 4 and 6 wt%. The gift card was crush and mix with the polyester and hardener followed by casting to get the suitable shape based on the testing. Three testing was undergone to evaluate the polymer blend properties which are tensile test, Charpy’s impact test and Durometer hardness test. Similar trend was shown for all mechanical testing which showing an increase of performance from 2 to 4 wt% addition of recycle cards but reduce when achieved 6 wt%.

Effect of Severe Acute Respiratory Syndrome Coronavirus 2 on Blood Product Utilization in the Community Hospital Setting

Introduction/Objective Blood products are a major expense for the laboratory, with an intricate balance between maintaining adequate supply and expiring products. Blood product wastage rates are typically less than 2%. The SARS-CoV-2 (SARS-CoV-2) pandemic has created a multifaceted challenge in blood utilization. Difficulties in predicting product usage, decreased supply, and transportation delays put hospitals at risk of increased blood product destruction. In this study, we analyze the effect of the SARS-CoV-2 pandemic on blood utilization in the community hospital setting, in order to develop improved laboratory management strategies for decreasing unit wastage. Methods/Case Report Quality indicators of blood utilization from 2012 to 2021 were retrospectively reviewed. Data was collected for packed red blood cells (pRBCs), platelets, and plasma. Units transfused, expired/destroyed, and total percent discarded were recorded for each month. Average transfusion and destruction rates were calculated for each product. Blood product utilization from 2020 was compared to years 2012-2019 using Pearson correlation, linear regression, and student paired t-tests. Results (if a Case Study enter NA) 1,042 units were reviewed. For pRBCs, there was a strong correlation between 2020 and increased destruction compared to 2012-2019 (R= 0.8, p=0.005). There was no significant change in pRBC transfusions in 2020 compared to 2018 and 2019 (p= 0.3, p= 0.2). There were fewer pRBC transfusions in 2020 compared to 2016 and 2017 (p= 0.006, p=0.01). For platelets, there was increased destruction in 2020 compared to 2012-2019 (p= 0.01-0.04) and no significant change in usage (p= 0.3-0.5). Conclusion During the 2020 SARS-CoV-2 pandemic, there was a significant increase in blood product wastage. There was no significant increase in transfused pRBCs or platelet units, suggesting the increased destruction was not due to an overall increase in transfusions. Blood products are a major cost for laboratory and further investigation of these findings is warranted to mitigate continued wastage.
