Authors: Huu Phuc Dang , Le Phan Xuan 
Published: July 2022

For a <span>colour conversion substance, we developed a new nanocomposite containing a CdSe/CdS/ZnS red-emitted quantum dot (QD), a green-emittedd <span>Sr<sub>2</sub>SiO<sub>4</sub>:Eu </span>phosphorus, and silicon resins. Regarding QD concentration and ingredients, the heat increase and optic features of the nanocomposite attributable to the QD inclusion were examined. According to the findings, a modest portion of QDs added to a photon converter at the emission wavelength of QD produced a considerable degree of heat. We used 0.2 wt% QDs over an InGaN blue-emitting light-emitted diodes (LED) chip to simulate a thermal increase in a nanocomposite. Consequently, we were able to produce a white-emitted LED module featuring a good 83.2 colour rendered index, an excellent 65.86 lm W-1 brightness, and a reasonable 94 °C thermal rise. The recently founded QD-phosphorus nanocomposite transformed white-emitted LED offers a lot of possibility of modern lighting.</span>

Published: July 2022

<span lang="EN-US">With various severe security threats for web applications, ensuring security on the database layer itself is imperative. Hence, this study aims to protect data saved on the computer or handheld online year-round (CHOY) registration system using the advanced encryption standard (AES) to strengthen data security within the app so that even potential attackers gain access to the app's database; they cannot obtain valuable information because it is scrambled and unreadable. The proponents based the study's conceptual framework on the symmetric and asymmetric key algorithms and procedures manual on enrollment of Southern Isabela College of arts and trades (SICAT) and ISO 25010. The study consists of three elements: developing the CHOY web app imbued with AES, testing it in terms of online registration and spam prevention, and evaluating it using the ISO 25010 in terms of compatibility, reliability, and security. The evaluation results show that implementing the AES in the CHOY web app meets the ISO 25010 criteria mentioned above.</span>

Hurricane Sally (2020) Shifts the Ocean Thermal Structure across the Inner Core during Rapid Intensification over the Shelf
Authors: Dzwonkowski B. , Fournier S. , Lockridge G. , Coogan J. , Liu Z. , Park K. 
Published: July 2022

Abstract
Prediction of rapid intensification in tropical cyclones prior to landfall is a major societal issue. While air–sea interactions are clearly linked to storm intensity, the connections between the underlying thermal conditions over continental shelves and rapid intensification are limited. Here, an exceptional set of in situ and satellite data are used to identify spatial heterogeneity in sea surface temperatures across the inner core of Hurricane Sally (2020), a storm that rapidly intensified over the shelf. A leftward shift in the region of maximum cooling was observed as the hurricane transited from the open gulf to the shelf. This shift was generated, in part, by the surface heat flux in conjunction with the along- and across-shelf transport of heat from storm-generated coastal circulation. The spatial differences in the sea surface temperatures were large enough to potentially influence rapid intensification processes suggesting that coastal thermal features need to be accounted for to improve storm forecasting as well as to better understand how climate change will modify interactions between tropical cyclones and the coastal ocean.

Significance Statement
The connections between the underlying thermal energy in the ocean that powers tropical cyclones and rapid intensification of storms over continental shelves are limited. An exceptional set of data collected in the field as well as from space with satellites was used to identify spatial variations in sea surface temperatures across the inner core of Hurricane Sally (2020), a storm that rapidly intensified over the shelf. The spatial differences were due to the heat loss from the surface of the ocean as well as heat transport by shelf currents. The spatial differences were large enough to potentially influence how quickly storms can intensify, suggesting that coastal thermal features need to be accounted for to improve storm forecasting.

Published: July 2022

Objectives: Schools that have partnerships with health services have shown improvements in attendance and academic performance. This study examined the effects of intersectoral educational training (IET) between the health and education sectors on students’ learning outcomes, emotional experiences and subjective task values. Design: In this experimental field study, students in the control group were taught about health by a regular team of teachers, the experimental group was taught by a teacher–general practitioner team. Qualitative and quantitative data were collected at three different points of time. Setting: The study was conducted with students aged between 13 and 14 years in three classes at a secondary school in Baden-Wuerttemberg. Methods: Data were collected on demographic variables as well as learning outcomes assessed by a multiple choice test. For the assessment of emotional experiences, the validated Achievement Emotions Questionnaire was used and for subjective task values a modified Motivated Strategies for Learning Questionnaire was employed. Quantitatively, descriptive statistics were calculated and correlation analyses were conducted to explore the association of positive emotions and task value with knowledge after the intervention and follow-up. Results: Over time, 69 of 76 participants (91%) completed all three surveys. Both groups showed significant and sustainable knowledge increases, but there were no significant differences between the groups in knowledge increase, positive emotions and task values. Conclusion: Health education in public secondary schools seems useful for increasing students’ health knowledge both in the short- and longer-term. However, future research will need to examine the potential effects of IET approaches on students’ cognitive and motivational experience.

Published: July 2022

Objective To evaluate the tolerability and efficacy of nasal pillow-noninvasive ventilation (NP-NIV) compared with high-flow nasal therapy (HFNT) in postsurgical patients. Methods This propensity score-matched retrospective study enrolled postoperative patients that received NP-NIV (NP-NIV group) or HFNT (HFNT group) in the intensive care unit. Data were collected from their medical records and the tolerability and respiratory status before and after extubation were compared between the two groups. Results The study enrolled 83 patients in the NP-NIV group and 27 patients in the HFNT group. After propensity score matching, there were 19 patients in each group. After matching, there were no significant differences in the baseline demographic and clinical characteristics before extubation. The tolerability was similar in both groups. When the NP-NIV group was compared with the HFNT group, the respiratory rate was significantly lower (median 16 [interquartile range, 14–17] versus median 19 [interquartile range, 18–26], respectively) and the partial pressure of arterial oxygen/fraction of inspired oxygen ratio was significantly higher (median 205 [174–256] versus median 155 [130–192], respectively) at 1 h after extubation. Conclusion NP-NIV was equally well tolerated and provided better respiratory support than HFNT in postsurgical patients.

Background: Lateral elbow tendinopathy is a disabling tendon overuse injury. It remains unknown if a corticosteroid injection (CSI) or tendon needling (TN) combined with heavy slow resistance (HSR) training is superior to HSR alone in treating lateral elbow tendinopathy. Purpose/Hypothesis: The purpose was to investigate the effects of HSR combined with either (1) a CSI, (2) TN, or (3) placebo needling (PN) as treatment for lateral elbow tendinopathy. We hypothesized that 12 weeks of HSR in combination with a CSI or TN would have superior effects compared with PN at 12, 26, and 52 (primary endpoint) weeks’ follow-up on primary (Disabilities of the Arm, Shoulder and Hand [DASH] score) and secondary outcomes in patients with chronic unilateral lateral elbow tendinopathy. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 60 patients with chronic unilateral lateral elbow tendinopathy were randomized to perform 12 weeks of home-based HSR with elastic band exercises combined with either (1) a CSI, (2) TN, or (3) PN, and at 12, 26, and 52 weeks, we assessed the primary outcome, the DASH score, and secondary outcomes: shortened version of the DASH (QuickDASH) score, pain (numerical rating scale [NRS] score), pain-free grip strength, and hypervascularization (power Doppler area). Results: A CSI, TN, and PN improved patient outcomes equally based on the DASH (Δ20 points), QuickDASH (Δ21 points), and NRS (Δ2.5 points) scores after 12 weeks. Further, after 12 weeks, a CSI also resulted in decreased hypervascularization (power Doppler area) compared with PN (Δ–2251 pixels, P = .0418). Except for the QuickDASH score (CSI increased score by Δ15 points compared with PN; P = .0427), there were no differences between the groups after 52 weeks. Conclusion: These results suggest that 12 weeks of HSR improved symptoms in both the short and the long term and that a CSI or TN did not amplify this effect. In addition, a CSI seemed to impair patient-reported outcomes compared with HSR alone at long-term follow-up. Registration: NCT02521298 ( ClinicalTrials.gov identifier).

Background Nepal is a South Asian country with a high burden of non-communicable diseases. Electronic health technologies are a promising strategy to mitigate the rising burden of non-communicable diseases by strengthening primary healthcare center service delivery. However, electronic health implementation in Nepal is limited. Furthermore, electronic health use at the primary healthcare center level is chronically understudied. This qualitative study seeks to understand the perceived awareness, benefits, and determinants of electronic health uptake in Nepal, focusing on primary healthcare center-level non-communicable disease management. Methods We conducted in-depth interviews with 27 participants including policymakers, health experts, facility administrators, providers, and non-communicable diseases patients in 2019. We selected six urban primary healthcare center facilities via cluster convenience sampling for recruiting facility administrators, providers, and patients, and used convenience sampling to recruit policymakers and experts. We conducted thematic data analysis inductively and deductively using the electronic health readiness assessment framework to understand perceived barriers and facilitators of electronic health implementation. Results While there was general awareness and acceptance of electronic health, multiple barriers impede readiness for implementation. These include policy making gaps, language barriers, low user technical literacy, concerns of overreliance on technology, and inadequate training for administrators and providers. Stakeholder suggestions include creating electronic health interfaces that meet the needs of end users (providers and patients), providing training to enable end users to effectively use electronic health technologies, and strong policy support at the national level. Conclusion We identify several determinants for effectively promoting the use of electronic health for non-communicable diseases service delivery at the primary healthcare center level in Nepal.
Understanding Redeployment During the COVID-19 Pandemic: A Qualitative Analysis of Nurse Reported Experiences
Authors: Kennedy Erin , Kennedy Patrick , Hernandez Joanna , Shakoor Kelly , Munyan Kristen 
Published: July 2022

Introduction The COVID-19 pandemic disrupted healthcare working conditions causing the redeployment of nurses. Redeployment refers to assigning healthcare workers to units or specialty areas where they do not regularly work. Objective The purpose of this study was to explore the lived experiences of redeployed nurses during the COVID-19 pandemic from April 27, 2020 to May 7, 2020. Methods Data collection occurred through a cross-sectional survey with demographic items and a single open-ended item. This open-ended item was part of a larger study regarding work conditions during the initial COVID-19 surge in the spring of 2020 in the Midwest United States (US). This analysis was performed separately due to the volume of qualitative responses and details provided. The survey was posted in private social media groups, and 298 nurses participated, 117 shared open-ended responses. Participants were asked what type of unit they worked on before COVID-19 and what unit they were deployed to. Findings Twenty-three (19.7%) reported deployment to COVID-designated units. Twenty-eight (23.9%) participants reported deployment to a unit outside of their specialty. Sixteen (13.7%) reported deployment from a non-critical care unit to an intensive care unit. Three major themes developed from the open-ended responses: (1) challenges related to their scope of practice and specialization, (2) challenges with interpersonal dynamics, and (3) challenges related to the environment. Conclusion The described challenges caused some nurses to report primarily negative experiences regarding redeployment during the COVID-19 pandemic. The findings add to the existing literature regarding redeployment and the vulnerability hospitals and their staff face during a disaster or pandemic-related events, such as COVID-19. Ultimately, aiding in the development of new policies to facilitate effective pandemic response in the future that would support nurses to participate in redeployment in a safe and nontraumatic way, is necessary.
The promising therapeutic effects of metformin on metabolic reprogramming of cancer-associated fibroblasts in solid tumors
Authors: Mostafavi Samaneh , Zalpoor Hamidreza , Hassan Zuhair Mohammad 
Published: July 2022

AbstractTumor-infiltrated lymphocytes are exposed to many toxic metabolites and molecules in the tumor microenvironment (TME) that suppress their anti-tumor activity. Toxic metabolites, such as lactate and ketone bodies, are produced mainly by catabolic cancer-associated fibroblasts (CAFs) to feed anabolic cancer cells. These catabolic and anabolic cells make a metabolic compartment through which high-energy metabolites like lactate can be transferred via the monocarboxylate transporter channel 4. Moreover, a decrease in molecules, including caveolin-1, has been reported to cause deep metabolic changes in normal fibroblasts toward myofibroblast differentiation. In this context, metformin is a promising drug in cancer therapy due to its effect on oncogenic signal transduction pathways, leading to the inhibition of tumor proliferation and downregulation of key oncometabolites like lactate and succinate. The cross-feeding and metabolic coupling of CAFs and tumor cells are also affected by metformin. Therefore, the importance of metabolic reprogramming of stromal cells and also the pivotal effects of metformin on TME and oncometabolites signaling pathways have been reviewed in this study.

Published: July 2022

AbstractBackgroundLong-term cultivation of ginseng can cause severe crop disorders and soil sickness. Crop rotation is an effective agricultural management measure to improve soil sustainability and decrease pathogens. However, the suitable ginseng rotation system and the changes in soil microbial community and soil characteristics under the rotation system need to be further explored.MethodsTo explore suitable ginseng crop rotation systems and improve soil utilization,Allium fistulosumandBrassica napuswere planted on ginseng cultivation soil for one year. The effects of the two crops on the chemical properties and enzyme activities of the ginseng cultivation soil were evaluated by chemical analysis. In addition, amplicon sequencing targeting 16 s rDNA genes of bacteria and ITS of fungi has been used to characterize the functional and compositional diversity of microbial communities.ResultsThe results elucidated that the levels of available phosphorus (AP) and available potassium (AK) in the soil increased significantly after one year of cultivation for both crops andAllium fistulosumcultivation may also have reduced soil salinity. In addition, the effects of the two crops on the activities of key soil enzymes were different. Catalase (CAT), urease (URE), and acid phosphatase (A-PHO) activities were significantly reduced and sucrase (SUC), and laccase (LAC) activities were significantly increased afterAllium fistulosumplanting. While A-PHO activity was significantly increased and LAC activity was significantly decreased afterBrassica napusplanting.Allium fistulosumsignificantly reduced the abundance of soil fungal communities. The cultivation ofAllium fistulosumandBrassica napussignificantly altered the composition of soil bacterial and fungal communities, where changes in the abundance of dominant microorganisms, such asAscomycota, andMortierellomycota, etc., were closely related to soil chemistry and enzyme activity. Moreover, both significantly reduced the abundance of the pathogenic fungusIlyonectria.ConclusionsOur study clarified the effects ofAllium fistulosumandBrassica napuson the microbial community and physicochemical properties of ginseng cultivated soil and provides a basis for the sustainable application of ginseng cultivation soil and the development of ginseng crop rotation systems.

Published: July 2022

Abstract
Background
The use of organic nanoparticles to improve drought resistance and water demand characteristics in plants seems to be a promising eco-friendly strategy for water resource management in arid and semi-arid areas. This study aimed to investigate the effect of chitosan nanoparticles (CNPs) (0, 30, 60 and 90 ppm) on some physiological, biochemical, and anatomical responses of Salvia abrotanoides under multiple irrigation regimes (30% (severe), 50% (medium) and 100% (control) field capacity).

Results
The results showed that drought stress decreases almost all biochemical parameters. However, foliar application of CNPs mitigated the effects caused by drought stress. This elicitor decreased electrolyte conductivity (35%), but improved relative water content (12.65%), total chlorophyll (63%), carotenoids (68%), phenol (23.1%), flavonoid (36.4%), soluble sugar (58%), proline (49%), protein (45.2%) in S. abrotanoides plants compared to the control (CNPs = 0). Furthermore, the activity of antioxidant enzymes superoxide dismutase (86%), polyphenol oxidase (72.8%), and guaiacol peroxidase (75.7%) were enhanced after CNPs treatment to reduce the effects of water deficit. Also, the CNPs led to an increase in stomatal density (5.2 and 6.6%) while decreasing stomatal aperture size (50 and 25%) and semi-closed stomata (26 and 53%) in leaves.

Conclusion
The findings show that CNPs not only can considerably reduce water requirement of S. abrotanoides but also are able to enhance the drought tolerance ability of this plant particularly in drought-prone areas.
