Veterans Affairs Health Care Provider Perceptions of Virtual Reality: Brief Exploratory Survey
Authors: Preston A'mie M , Brown Lana , Padala Kalpana P , Padala Prasad R 
Published: August 2022

Background
Virtual reality (VR), a simulated experience that can be similar to or completely different from the real world, has become increasingly useful within the psychiatric and medical fields. This VR technology has been applied in medical school trainings, exposure therapy for individuals with posttraumatic stress disorder (PTSD), and reminiscence therapy associated with mood disorders for older adults. Perceptions of VR through the lens of the health care provider require further exploration. VR has grown in popularity; however, this modality continues to be underused in most Veterans Affairs (VA) hospitals.

Objective
A web-based survey was used to explore health care provider perceptions of immersive VR availability and use for older adults and identify potential barriers for immersive VR use in older adults with cognitive impairment.

Methods
An 8-item web-based survey was developed to obtain health care provider feedback. This survey was disseminated throughout a single Veterans Integrated Services Network (VISN). The VR survey was developed via the Survey Monkey platform and distributed through the secure VA email network. Providers were asked to voluntarily participate in the brief, anonymous survey and offer their perceptions of immersive VR use within their patient population. Survey data were reviewed and interpreted using descriptive statistics.

Results
A total of 49 respondents completed the survey over a 15-day period. Of them, 36 respondents (73%) had heard of a VR device, though the majority (n=44, 90%) had never used or prescribed a VR device. Respondents identified several potential barriers to immersive VR use in older adults with cognitive impairment (eg, hearing difficulties, perceptions of technology, cognitive concerns, access to resources, and visual impairment). Despite the barriers identified, providers (n=48, 98%) still reported that they would feel comfortable prescribing immersive VR as an intervention for their patient population.

Conclusions
Survey findings revealed that health care providers within this VISN for VAs have heard of VR, although they may not have actively engaged in its use. Most of the providers reported that they would prescribe the use of an immersive VR intervention for their older adult patients. This key point highlights the desire to implement VR strategies for patient use by their providers. If underlying barriers can be addressed and relatively resolved, this technological intervention has the potential to create substantial breakthroughs in clinical care.

Students’ approaches to learning are an important tool used by researchers in the field of educational psychology. The theory assumes that students have two basic ways of approaching objects of knowledge, a deep one and a superficial one. Both are reasonable predictors of academic performance. The study of the learning process requires instruments to be applied to students, nevertheless, the exclusive use of self-report instruments has substantially hindered an adequate study of this process. The Laboratory for Research on Cognitive Architecture (LAICO) at the Federal University of Minas Gerais brought forth an important recent contribution to learning approaches. This is the development of the Approach-in-Process Test (Version 2) which measures the students' process when using their learning approaches. The Approach-in-Process Test (Version 2) is completely original since it is a test based on performance that measures students’ learning approach in the academic learning context. In this paper, we make a presentation of the Approach-in-Process Test (Version 2) where we show in detail its structure and content.

Abstract

Introduction
A low concentration of ketamine is used to cause an anti-depressive effect. The mechanism of ketamine's action in depression is believed to result, among others, from its anti-inflammatory activity. Despite the fact that only high concentrations of ketamine inhibit bacterial growth, it is clear that even a sub-inhibitory concentration of chemicals may change bacterial properties. Considering the above, in the current study we aimed to evaluate the in vitro influence of ketamine on proliferation of enterococci and their interactions with monocytes.

Materials and Methods
The studied strains were isolated as etiological agents of infection at Medical University of Gdansk. The proliferation and metabolic activity were determined using the FACSVerse flow cytometer after addition of CFDA-SE to bacterial suspension. For the determination of phagocytosis resistance, THP-1 human monocytes cell line was used. Suspension of monocytes which engulfed CFDA-SE–stained bacteria was then stained with propidium iodide to evaluate cytotoxicity of enterococci.

Results
The result of the study showed unexpected response of bacterial cells to ketamine at an early stage of culture. In 57.7% of strains, both proliferation rate and metabolic activity were boosted. This group of strains was also less susceptible to phagocytosis than in culture without ketamine. Different response of isolates to ketamine was also visible in changes of proteins’ profile determined by MALDI-TOF.

Conclusions
The analysis of bacteria at an early stage in the growth curve demonstrated the bacterial diversity in response to ketamine and let us set the hypothesis that microbiome susceptibility to ketamine may be one of the elements which should be taken into consideration when planning the successful pharmacotherapy of depression
How important are remittances to savings? Evidence from the Latin America and the Caribbean Countries

Published: August 2022

Abstract
This paper investigates the direct and the indirect roles of migrant transfers in the saving behaviors of the Latin America and Caribbean (LAC) countries during the period 1997–2018. Using the autoregressive distributed lag (ARDL) panel estimation technique, the results based on the Pooled Mean Group approach provide strong evidence of the importance of inward remittances to savings. On average, an increase in inward remittances by 1% leads to about 0.10% increase in savings ceteris paribus, but the effect is quantitatively larger in the short-run than in the long-run, albeit more significant in the latter case. Quite outstanding here is the observation of the detrimental role of remittances on savings in the long-run once governance quality in aggregate and disaggregated forms are controlled for, suggesting possible adverse effects of remittances for economic development in the long-run. Nevertheless, macroeconomic stability as well as institutional quality, foreign direct investment (FDI), and foreign aid were found to be important moderators of the remittances–savings linkage. For the latter two variables, emphasis is on complementarity rather than substitutability between remittances, aid, and FDI. While in the short-run remittances appear to perform better in enhancing savings in countries where an improvement in corruption control is visible, political rights and civil liberties compliment migrant transfers in propelling savings in the long- and short-runs, respectively. Moreover, remittances are found to play a major role in ameliorating the adverse effects of the financial crisis on savings, just as they are observed to function as a lifeline to savings in countries with increasing macroeconomic instability in form of inflation, in the long-run. The findings are robust to the use of alternative estimation techniques. Policy recommendations are suggested.

The use of herbal medicines as antioxidants has increased recently. One of them is gaharu leaf (Gyrinops versteegii). Gaharu plants have been widely used by people to treat various types of diseases. Papuan people have used the roots, bark and leaves of gaharu as malaria medicine and skin treatment. This research intended to ascertain the total content of flavonoids and antioxidant capacity of the n-hexane fraction in gaharu leaves’ extract. A total amount of 100 g dry powders of gaharu leaves, with water content of 8.59%, macerated with 96% ethanol, resulted in 10 g of concentrated extract obtained by evaporation using vacuum rotary evaporator. This extract then proceeded to the fractionation stage using solvents such as n-hexane, chloroform and ethyl acetate. The results obtained were 5.66 g of n-hexane, 2.23 g of chloroform, 0.85 g of ethyl acetate and 1.14 g of the remaining water extract. Phytochemical screening showed that the n-hexane extract positively contained flavonoids with the highest total flavonoid contents of 1557.66 mg QE/100 g. In-vitro test for the antioxidant activity of the n-hexane fraction utilizing the procedure of DPPH (1,1-diphenyl-2-picrylhydrazyl) showed the IC50 value of 126.76 ppm. These results indicate that the n-Hexane fraction of gaharu leaves’ extract has a high total flavonoid contents and consists of active antioxidant compounds with medium capacity.

Lead (Pb) is a common pollutant found in agricultural soils and often contaminates the plants growing on the soil. One way to reduce the content of heavy metal contamination such as Pb in agricultural soil is through phytoremediation. The purpose of this study was to reduce the content of Pb in agricultural soils. The method used was remediation by planting gumitir (Tagetes erecta L.) plants on the soil added with various concentrations of Pb2+. The results showed that before planting with gumitir, the soil A, B, C added with Pb of 100; 200; and 400 mg Pb/kg soil, respectively, having the concentration of 108,97±2,25; 214,18±5,47; and 447,04±4.89 mg/kg, respectively, while on the harvesting time the concentration of Pb was 100,52±1,66; 170,04±2,88; and 397,98±2,24 mg/kg, respectively. The part of the plant that absorbed the highest Pb was the root, which was 47,01±4,52 mg/kg. The effectiveness of Pb absorption by gumitir plants in A, B, and C soils were <50% with TF and BCF values ??< 1, so the mechanism in accumulating lead metal is less effective or called phytostabilization.

Published: August 2022

One way to reduce phosphate levels in water is by adsorption. Adsorption is considered as the best wastewater treatment method because the main material, namely adsorbent, is abundant and easy to use. This research was conducted to determine the ability of zeolite combined with bentonite to adsorb phosphate in water, the optimum time, the pattern of adsorption isotherms and the adsorption capacity. The studies included the characterization of the adsorbent as well as its application to adsorb phosphate with various contact times and concentrations. The surface area of the adsorbents was characterized by the methylene blue adsorption method and the active site by acid-base titration. The specific surface area of ??each adsorbent had almost the same value, but the largest was the combination of zeolite: bentonite (1:1) which was 45.9637 m2/g. The largest active site of the adsorbent was the combination of zeolite: bentonite (1:1) adsorbent, which is 1.2842×1024 sites/g adsorbent. All the zeolite : bentonite combination adsorbents had the same optimum contact time of 24 hours. The zeolite: bentonite (5:0) followed the Langmuir adsorption isotherm pattern, while the zeolite : bentonite (1:1) followed the Freundlich isotherm pattern. Zeolite : bentonite (5:0), (1:1), and (0:5) had the optimum adsorption capacity at the concentration of 100 ppm with the percentage of phosphate adsorbed of 96.66; 97.67; 97.02%, respectively, so it showed that the zeolite : bentonite (1:1) adsorbed the most phosphate.
