Background
Although psychological sequelae after intensive care unit (ICU) treatment are considered quite intrusive, robustly effective interventions to treat or prevent these long-term sequelae are lacking. Recently, it was demonstrated that ICU-specific virtual reality (ICU-VR) is a feasible and acceptable intervention with potential mental health benefits. However, its effect on mental health and ICU aftercare in COVID-19 ICU survivors is unknown.

Objective
This study aimed to explore the effects of ICU-VR on mental health and on patients’ perceived quality of, satisfaction with, and rating of ICU aftercare among COVID-19 ICU survivors.

Methods
This was a multicenter randomized controlled trial. Patients were randomized to either the ICU-VR (intervention) or the control group. All patients were invited to an COVID-19 post-ICU follow-up clinic 3 months after hospital discharge, during which patients in the intervention group received ICU-VR. One month and 3 months later (4 and 6 months after hospital discharge), mental health, quality of life, perceived quality, satisfaction with, and rating of ICU aftercare were scored using questionnaires.

Results
Eighty-nine patients (median age 58 years; 63 males, 70%) were included. The prevalence and severity of psychological distress were limited throughout follow-up, and no differences in psychological distress or quality of life were observed between the groups. ICU-VR improved satisfaction with (mean score 8.7, SD 1.6 vs 7.6, SD 1.6 [ICU-VR vs control]; t64=–2.82, P=.006) and overall rating of ICU aftercare (mean overall rating of aftercare 8.9, SD 0.9 vs 7.8, SD 1.7 [ICU-VR vs control]; t64=–3.25; P=.002) compared to controls. ICU-VR added to the quality of ICU aftercare according to 81% of the patients, and all patients would recommend ICU-VR to other ICU survivors.

Conclusions
ICU-VR is a feasible and acceptable innovative method to improve satisfaction with and rating of ICU aftercare and adds to its perceived quality. We observed a low prevalence of psychological distress after ICU treatment for COVID-19, and ICU-VR did not improve psychological recovery or quality of life. Future research is needed to confirm our results in other critical illness survivors to potentially facilitate ICU-VR’s widespread availability and application during follow-up.

Loss of Weight Gained During the COVID-19 Pandemic: Content Analysis of YouTube Videos
Authors: Tang Hao , Kim Sungwoo , Laforet Priscila E , Tettey Naa-Solo , Basch Corey H 
Published: January 2022

Background
Many people experienced unintended weight gain during the COVID-19 pandemic, which has been discussed widely on social media.

Objective
This study aims to describe the content of weight loss videos on YouTube (Google LLC) during the COVID-19 pandemic.

Methods
By using the keywords weight loss during quarantine, the 100 most viewed English-language videos were identified and coded for content related to losing weight gained during the COVID-19 pandemic.

Results
In total, 9 videos were excluded due to having non-English content or posting data before the COVID-19 pandemic. The 91 videos included in the study sample acquired 407,326 views at the time of study and were roughly 14 minutes long. A total of 48% (44/91) of the sample videos included graphic comparisons to illustrate weight change. Videos that included a graphic comparison were more likely to have content related to trigger warnings (χ21=6.05; P=.01), weight loss (χ21=13.39; P<.001), negative feelings during quarantine (χ21=4.75; P=.03), instructions for losing weight (χ21=9.17; P=.002), self-love (χ21=6.01; P=.01), body shaming (χ21=4.36; P=.04), and special dietary practices (χ21=11.10; P<.001) but were less likely to include food recipes (χ21=5.05; P=.03). Our regression analysis results suggested that mentioning quarantine (P=.05), fat-gaining food (P=.04), self-care and self-love (P=.05), and body shaming (P=.008) and having presenters from both sexes (P<.001) are significant predictors for a higher number of views. Our adjusted regression model suggested that videos with content about routine change have significantly lower view counts (P=.03) than those of videos without such content.

Conclusions
The findings of this study indicate the ways in which YouTube is being used to showcase COVID-19–related weight loss in a pre-post fashion. The use of graphic comparisons garnered a great deal of attention. Additional studies are needed to understand the role of graphic comparisons in social media posts. Further studies that focus on people’s attitudes and behaviors toward weight change during the COVID-19 pandemic and the implications of social media on these attitudes and behaviors are warranted.

Published: January 2022

Potential forest carbon stocks are significantly correlated to forest biodiversity attributes such as diversity, density, and richness. However, there is little such information on dry tropical reserve forests of Assam, a state in northeast India. We studied this relationship in two reserve forests. Pearson correlation, cluster analysis, and regression analysis were used to explore these relationships. The estimation of plant carbon stocks was made using both destructive methods for herbaceous and non-destructive allometric methods for trees. The most dominant plant species in the Bhomoraguri reserve forest were Cynodon dactylon, Datura stramonium, Clitoria ternatea, and Tectona grandis for grasses, forbs, climbers, and trees, respectively. Cymbopogon nardus, Colocasia esculenta, Mikania micrantha, and Shorea robusta, were dominant species in the Balipara reserve forest for grasses, forbs, climbers, and trees, respectively. The presence of Lantana camara, Smilax ovalifolia and Piper betle in the studied forests suggests disturbed ecosystems. Other observed species such as Aristida spp., Cenchrus spp., Ipomoea cheirophylla, and Sida spp. are indicators of disturbed ecosystems as well. The biomass stock differed significantly among plant growth forms. Carbon stocks were 302.93 and 283.97 t ha–1 in the Bhomoraguri reserve forest and Balipara reserve forest, which were equivalent with 555.87 and 521.30 t ha–1 of CO2 sequestration, respectively. Tree species contributed the greatest amount (54.80%), followed by forbs (21.36%), climbers (19.35%), and least for grasses (4.49%). Correlation analysis indicated a strong positive relationship between the density of trees and climber species with carbon stock potentials, suggesting that increase of their density favoured carbon sequestration in forest ecosystems. Diversity of grasses was negatively correlated with potential carbon stock in the examined forests. The unique contribution of each group to carbon stock was 91.8, 58.01, 51.3, and 11.11% for climbers, trees, grasses, and forbs, respectively. Thus, it is important to examine biodiversity attributes in estimation of forest carbon stocks.

Published: January 2022

The aim of the present study was to compare soil chemical composition and aspects of mineral nutrition of several accessions from different geographically isolated sites in Latvia of Trifolium fragiferum L., a crop wild relative plant species. Eight geographically isolated micropopulations of T. fragiferum in Latvia were identified, and material was sampled for analysis of plant-available mineral nutrient concentrations in soil and mineral nutrient concentrations in leaf tissues. Micropopulations of T. fragiferum were associated with rivers, lakes and the sea, thus also outside typical coastal or inland-located salt-affected grassland habitats. Soil concentration of plant-available mineral nutrients showed significant variation between different sites, ranging from 59% for N to 193% for Ca. Variation in mineral element concentration in plant leaf tissues was relatively lower. Multivariate analysis showed that sites with similar localization on river shores or in coastal areas had similar characteristics, as these were grouped together according to both soil mineral nutrient availability as well as leaf tissue mineral element concentrations. T. fragiferum can be characterized as a species able to maintain mineral homeostasis in leaf tissues irrespective of large variability in soil plant-available mineral nutrient concentrations and different levels of soil pH. Together with general resilience to environmental constraints, this allows to predict a relatively good conservation status of T. fragiferum in Latvia in spite of rather limited number and size of the geographically isolated micropopulations.

Published: January 2022

SUMMARY
This study aimed to evaluate the effect of the bleaching gel application site on chromatic changes and postoperative sensitivity in teeth. Thirty patients were selected and allocated to three groups (n=10 per group), according to the location of the gel: GI, cervical application; GII, incisal application; and GIII, total facial. The amount and time of application of the 35% hydrogen peroxide (H2O2) gel were standardized. Color changes were analyzed by ΔE and Wid (bleaching index), using the values obtained in the readings conducted on a digital spectrophotometer in the cervical (CRs) and incisal regions (IRs) of the teeth. Spontaneous sensitivity was assessed using the questionnaire, and the stimulated sensitivity caused by the thermosensory analysis (TSA). The analysis occurred in five stages: baseline, after the first, second, and third whitening sessions (S), and 14 days after the end of the whitening, using the linear regression statistical model with mixed effects and post-test by orthogonal contrasts (p&lt;0.05). Although the IR was momentarily favored, at the end of the treatment, the restriction of the application site provided results similar to those obtained when the gel was applied over the entire facial surface. Regarding sensitivity, only the GI showed spontaneous sensitivity. In the TSA, GIII had less influence on the threshold of the thermal sensation. It was concluded that the chromatic alteration does not depend on the gel application site. Spontaneous sensitivity is greater when the gel is concentrated in the cervical region (CR), and the teeth remain sensitized by thermal stimuli even after 14 days.

SUMMARYObjectivesThis study aimed to investigate the effects of hydrothermal treatment on four types of monolithic, translucent, yttria-stabilized, tetragonal zirconia polycrystals (Y-TZPs).Methods and MaterialsTwo commercially available Y-TZP brands—SuperfectZir High Translucency (Aidite Technology Co, China) and Katana HT (Kuraray Noritake Dental, Japan) were assessed. For each brand of Y-TZP, materials of four coloring types, including noncolored (NC), colored by staining (CS), precolored (PC), and multilayered (ML) specimens were investigated after hydrothermal aging in an autoclave at 134°C/0.2 MPa for 0 (control group), 5, 10, and 20 hours. The tetragonal-to-monoclinic phase transformation, surface roughness, flexural strength, and structural reliability (Weibull analysis) were measured and statistically analyzed (α=0.05). The subsurface microstructure was analyzed with scanning electron microscopy.ResultsThe group ML exhibited the lowest flexural strength and Weibull characteristic strength among the four coloring types (p&lt;0.05). Slight increases in the monoclinic phase volume, flexural strength, and Weibull characteristic strength were observed after hydrothermal aging (pall&lt;0.05). Regardless of coloring type, no significant effects of aging on the Weibull modulus or surface roughness were found for the tested materials. Compared with the Katana HT cross-sections, the SuperfectZir High Translucency cross-sections exhibited a similar but thicker transformation zone.ConclusionsThe coloring procedure and material type were found to affect the mechanical properties and aging resistance of translucent monolithic Y-TZP ceramics. Regardless of the aging time, the surface roughness of the tested Y-TZP ceramics remained unchanged.

ITB STIKOM BALI is an educational institution that uses a lecturer information system to help work. However, there are still some obstacles regarding how effective the lecturers' satisfaction is in using the Lecturer Information System. This research is focused on the analysis of the effectiveness of satisfaction using the Lecturer Information System as measured by the PIECES variables. The population of this study includes all active lecturers who use the lecturer information system as many as 155 people. The samples were determined by applying the SRS (Simple Random Sampling) technique using tables developed by Isaac and Michael. Of the 155 populations based on the 10% significance calculation selected to get a total of 99 samples, data collection was carried out by giving a questionnaire to all samples and there were as many as 93 people that returned it. The technique used to evaluate the Lecturer Information System is the PIECES method which focuses on 6 variables; Performance, Information, Economic, Control, Efficiency, and Service. This technique is more suitable to use and can focus on measuring the accuracy of each variable. To measure the level of user satisfaction from each variable, the questionnaire had 17 statements using a Likert scale to determine the value of the user's opinion on the system. The results of the analysis were obtained from the calculation of the questionnaire value of all respondents using the satisfaction calculation formula developed by Kaplan and Norton. From the reference criteria for the assessment of satisfaction, the results of the analysis show that the average value is 3.4 - 4.91, which means that users are satisfied using the Lecturer Information System with details of the scores on the variables Performance 4.19, Information 4.16, Economic 4.26, Control 3.85, Efficiency 4.23, and Service 4.21. It can be concluded that the use of Lecturer Information Systems statistically shows that it is quite effective. After getting the results of the value of each variable, a summary of recommendations will be given based on the smallest value in the sub-variables in each variable that received dissatisfied and very dissatisfied responses from the average questionnaire value.
