Authors: Li Liangliang , Zhang Yueying , Fan Mingyue , Cao Bing 
Published: April 2024

Abstract
Objective
Sleep problems and their detrimental effects on adolescents’ physical and mental health have received substantial attention. Prior studies have focused mainly on the direct association between sleep and mental health; however, little is known about the underlying mediating mechanism. To address this gap, the present study constructed a chain mediation model to examine the association between sleep deficiency and mental health status in adolescents, by introducing two mediating variables-physical health perception and school adjustment.

Methods
A sample of 7530 senior high school students completed a battery of self-report questionnaires measuring their sleep duration, mental health status, physical health perception, and school adjustment. Data were collected from the Database of Youth Health at Shandong University. All the measures showed good reliability and validity in the present study. Data were analyzed using SPSS 25.0 and the SPSS PROCESS.

Results
The results were as follows: (1) Sleep duration was significantly associated with physical health perception and mental health. (2) Physical health perception partially mediated the association between sleep and mental health. (3) Physical health perception and school adjustment played a chain mediating role between sleep and mental health. In conclusion, sleep not only directly associated with mental health among adolescents, but also influences mental health by the chain mediating effect of perception of physical health and school adjustment.

Conclusion
These findings in the present study contribute to understanding the mechanisms underlying the association between sleep and mental health and have important implications for interventions aimed at improving mental health status among adolescents in China. Our results indicated that promoting adequate sleep duration and improving sleep quality are possible key mental health promotion strategies for adolescents.

Published: April 2024

Abstract
Purpose
Dental implants have been successfully implemented as a treatment for tooth loss. However, peri-implantitis, an inflammatory reaction owing to microbial deposition around the implant, can lead to implant failure. So, it is necessary to treat peri-implantitis. Therefore, this numerical study is aimed at investigating conditions for treating peri-implantitis.

Methods
Photothermal therapy, a laser treatment method, utilizes photothermal effect, in which light is converted to heat. This technique has advantage of selectively curing inflamed tissues by increasing their temperature. Accordingly, herein, photothermal effect on peri-implantitis is studied through numerical analysis with using Arrhenius damage integral and Arrhenius thermal damage ratio.

Results
Through numerical analysis on peri-implantitis treatment, we explored temperature changes under varied laser settings (laser power, radius, irradiation time). We obtained the temperature distribution on interface of artificial tooth root and inflammation and determined whether temperature exceeds or does not exceed 47℃ to know which laser power affects alveolar bone indirectly. We defined the Arrhenius thermal damage ratio as a variable and determined that the maximum laser power that does not exceed 47℃ at the AA’ line is 1.0 W. Additionally, we found that the value of the Arrhenius thermal damage ratio is 0.26 for a laser irradiation time of 100 s and 0.50 for 500 s.

Conclusion
The result of this numerical study indicates that the Arrhenius thermal damage ratio can be used as a standard for determining the treatment conditions to help assisted laser treatment for peri-implantitis in each numerical analysis scenario.
Intrinsic conformal order revealed in geometrically confined long-range repulsive particles
Authors: Yao Zhenwei 
Published: April 2024

Abstract
Elucidating long-range interaction guided organization of matter is a fundamental question in physical systems covering multiple length scales. Here, based on the hexagonal disk model, we analyze the characteristic inhomogeneity created by long-range repulsions, and reveal the intrinsic conformal order in particle packings in mechanical equilibrium. Specifically, we highlight the delicate angle-preserved bending of the lattice to match the inhomogeneity condition. The revealed conformal order is found to be protected by the surrounding topological defects. These results advance our understanding on long-range interacting systems, and open the promising possibilities of using long-range forces to create particle packings not accessible by short-range forces, which may have practical consequences.
Deferred revascularization in diabetic patient according to combined invasive functional and intravascular imaging data: A case report
Authors: Al Nooryani Arif , Aboushokka Wael , Beleslin Branko , Nedeljkovic-Beleslin Biljana 
Published: April 2024

BACKGROUND
Invasive functional evaluation by fractional flow reserve (FFR) is considered as a gold standard for the evaluation of intermediate coronary stenosis. However, in patients with diabetes due to accelerated progression of atherosclerosis the outcome may be worse even in the presence of negative functional testing.
CASE SUMMARY
We present a case of 55-year-old male diabetic patient who was admitted for chest pain. Diagnostic coronary angiography disclosed 2 intermediate stenoses of the obtuse marginal branch with no evidence of restenosis on previously implanted stent. Patient undergone invasive functional testing of intermediate lesion with preserved FFR (0.88), low coronary flow reserve (1.2) and very high index of microvascular resistance (84). Due to discrepancy in invasive functional parameters, intravascular imaging with optical coherence tomography showed fibrotic stenoses without signs of thin-sup fibroatheroma. Because of the preserved FFR and no signs of vulnerable plaque, the interventional procedure was deferred and the patient continued with optimal medications.
CONCLUSION
Combined functional and anatomic imaging of intermediate coronary stenosis in diabetic patients represent comprehensive contemporary decision pathway in the management of the patients.
Text information security protection method based on computer-generated holograms

Published: April 2024

Currently, computer-generated holograms (CGHs) based on ray tracing technology are generated faster and faster, and the reconstructed scenes are getting bigger and bigger and contain more and more information. Based on this situation, there are also more applications of using CGHs to hide information, but there is a lack of research on the ability to hide information. To address this issue, this paper proposes a point-sampling CGH method based on ray tracing. Our method utilizes ray tracing techniques to rapidly sample text information at different depths in the scene and hides the depth-encoded text information in the carrier image using discrete cosine transform. The reconstructed image after embedding shows good results, with a peak signal-to-noise ratio (PSNR) of 29.56 dB between the hidden images before and after embedding. The PSNR value between the embedded carrier image and the original carrier image is 51.66 dB, making it difficult for the human eye to distinguish, thereby effectively protecting the generated CGH. We also analyzed the maximum information density and observed that computational holograms obtain the maximum information density at 200×200 resolution.
Smoking as a risk factor for lower extremity peripheral artery disease in women compared to men: A systematic review and meta-analysis
Authors: Xu Ying , Pouncey Anna Louise , Zhou Zien , Woodward Mark , Harris Katie 
Published: April 2024

Background
To investigate whether the relationship between smoking and peripheral artery disease (PAD) differs by sex (PROSPERO CRD42022352318).

Methods
PubMed, EMBASE, and CINAHL were searched (3 March 2024) for studies reporting associations between smoking and PAD in both sexes, at least adjusted for age. Data were pooled using random effects. Between-study heterogeneity was examined using I2 statistic and Cochran’s Q test. Newcastle-Ottowa Scale was adopted for quality assessment.

Results
Four cohort studies (n = 2,117,860, 54.4% women) and thirteen cross-sectional studies (n = 230,436, 59.9% women) were included. In cohort studies, former and current smokers had higher risk of PAD than never smokers. Compared to those who never or previously smoked, women current smokers (relative risk (RR) 5.30 (95% confidence interval 3.17, 8.87)) had higher excess risk of PAD than men (RR 3.30 (2.46, 4.42)), women-to-men ratio of RR 1.45 (1.30, 1.62)(I2 = 0%, p = 0.328). In cross-sectional studies, risk of PAD was higher among former and current compared to never smokers, more so in men, women-to-men ratios of odds ratio: 0.64 (0.46, 0.90)(I2 = 30%, p = 0.192), 0.63 (0.50, 0.79)(I2 = 0%, p = 0.594), respectively. For both sexes, risk of PAD was higher among current smokers compared to those who were not currently smoking. Cohort studies and five cross-sectional studies were of good quality, scoring 6 to 8 of a possible maximum 9 points. Eight cross-sectional studies scored 2 to 5.

Discussions
Further research is required to elucidate sex differences in the relationships between smoking and PAD, as the current evidence is limited and mixed. Tobacco-control programs should consider both sexes.

A novel investigation of co-processing porous geopolymer using glass fibres recycled from waste turbine blades
Authors: Wang Kaibao , Yang Liu 
Published: April 2024

Abstract
This work investigates the possibility of using recycled glass fibre (rGF) to co-process porous geopolymer. A new procedure was developed to incorporate rGF into geopolymer preparation and the content of rGF in porous geopolymer was varied to investigate its effect on thermal and mechanical properties. The rGF was co-processed through mixing with a combination of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) solution to supplement raw materials required to make geopolymer but also provide fibres as potential structure reinforcement. Due to the enriched silica content obtained from rGF and leftover fibres, a nearly 80 % strength increase (from 0.092 MPa to 0.165 MPa) was obtained without compromising its low thermal conductivity. This opens up a potential route to re-using rGF in the development of improved porous geopolymer for thermal insulation applications.
A double-pass optical beam deflection instrument for the measurement of diffusion, thermodiffusion and Soret coefficients in liquid mixtures and its application to polymer analysis
Authors: Reh Roman , Hager Mareike , Köhler Werner 
Published: April 2024

Abstract
We have developed a new double-pass optical beam deflection instrument for the measurement of diffusion, thermodiffusion and Soret coefficients in liquid mixtures. The increased sensitivity of the instrument results from a second passage of the readout laser beam through the Soret cell containing the sample. An elegant description of the total beam deflection is achieved by means of a transfer matrix formalism. The higher sensitivity allows for a reduction of the length of the detection arm and a compact and stiff design of the instrument. The performance of the new apparatus is demonstrated by its application to polymer analysis for the determination of the molar mass distribution of the polymer from the distribution of diffusion rates by means of the CONTIN algorithm.

Published: April 2024

Abstract
In the last century, global awareness of the environmental repercussions associated with petroleum-based polymer composites has surged. This realization urged extensive scientific research directed towards plant-based biomass, particularly nanocellulose, as a reinforcing element in polymer matrices. Global market value of nanocellulose is expected to increase considerably by 2025, to a forecast USD 783 million. Despite nanocellulose’s performance benefits, its poor compatibility with hydrophobic polymer matrices poses challenges, limiting thermal stability and impeding widespread commercialization at higher processing temperatures. To overcome these issues, chemical modification or functionalization emerges as a promising solution to enhance nanocellulose-based polymer nanocomposites’ thermal stability. The abundance of hydroxyl groups on nanocellulose enables specific chemical modifications, such as grafting functional molecules or forming covalent/ionic bonds with the polymer matrix. The aim of this study is to validate that integrating chemically functionalized nanocellulose into various polymer matrices, including thermoset, thermoplastic, and bio-polymer, enhances the thermal stability of resulting polymer nanocomposites, supported by thermogravimetric analysis (TGA). The study also explores six additional factors influencing TGA in nanocomposites, providing a comprehensive understanding of elements impacting the thermal properties of these materials.
Emergency Department–Based Physical Function Measures for Falls in Older Adults and Outcomes: A Secondary Analysis of GAPcare
Authors: Strauss Daniel H. , Davoodi Natalie M. , Resnik Linda J. , Keene Sarah , Serina Peter T. , Goldberg Elizabeth M. 
Published: April 2024

Background and Purpose:
Falls are the leading reason for injury-related emergency department (ED) visits for older adults. The Geriatric Acute and Post-acute Fall Prevention Intervention (GAPcare), an in-ED intervention combining a medication therapy management session delivered by a pharmacist and a fall risk assessment and plan by a physical therapist, reduced ED revisits at 6 months among older adults presenting after a fall. Our objective was to evaluate the relationship between measures of function obtained in the ED and clinical outcomes.

Methods:
This was a secondary analysis of data from GAPcare, a randomized controlled trial conducted from January 2018 to October 2019 at 2 urban academic EDs. Standardized measures of function (Timed Up and Go [TUG] test, Barthel Activity of Daily Living [ADL], Activity Measure for Post Acute Care [AM-PAC] 6 clicks) were collected at the ED index visit. We performed a descriptive analysis and hypothesis testing (chi square test and analysis of variance) to assess the relationship of functional measures with outcomes (ED disposition, ED revisits for falls, and place of residence at 6 months). Emergency department disposition status refers to discharge location immediately after the ED evaluation is complete (eg, hospital admission, original residence, skilled nursing facility).

Results and Discussion:
Among 110 participants, 55 were randomized to the GAPcare intervention and 55 received usual care. Of those randomized to the intervention, 46 received physical therapy consultation. Median age was 81 years; participants were predominantly women (67%) and White (94%). Seventy-three (66%) were discharged to their original residence, 14 (13%) were discharged to a skilled nursing facility and 22 (20%) were admitted. There was no difference in ED disposition status by index visit Barthel ADLs (P = .371); however, TUG times were faster (P = .016), and AM-PAC 6 clicks score was higher among participants discharged to their original residence (P ≤ .001). Participants with slower TUG times at the index ED visit were more likely to reside in nursing homes by six months (P = .002), while Barthel ADL and AM-PAC 6 clicks did not differ between those residing at home and other settings.

Conclusions:
Measures of function collected at the index ED visit, such as the AM-PAC 6 clicks and TUG time, may be helpful at predicting clinical outcomes for older adults presenting for a fall. Based on our study findings, we suggest a novel workflow to guide the use of these clinical measures for ED patients with falls.

Published: April 2024

BACKGROUND AND OBJECTIVES
The coronavirus disease 2019 (COVID-19) pandemic contributed to the public health crisis for pediatric mental health. We characterized our local patient population presenting with suicidality or suicide attempts before and after the pandemic by examining: 1. frequencies of hospitalizations for suicidality to determine whether they differed by age, legal sex, race and ethnicity, or socioeconomic status; 2. average length of stay and discharge disposition; 3. 7-, 30-, and 365-day reutilization rates; and 4. admission trends during COVID-19 surges.

METHODS
Retrospective data between March 2018 and March 2022 was analyzed, including patients ages 10 to 17 years hospitalized for either suicidality or a suicide attempt at 1 freestanding tertiary care pediatric medical hospital in the Midwest. Encounters were divided into 2 categories on the basis of the COVID-19 pandemic: “Prelockdown” (March 1, 2018–March 12, 2020) and “postlockdown” (March 13, 2020–March 31, 2022). Patients were limited to 1 presentation pre- and postlockdown. We analyzed frequencies using means and SDs, categorical data using χ2 and Fisher’s exact tests, and continuous data with t tests.

RESULTS
A total of 1017 encounters were included, stratified into pre- and postlockdown groups for analysis (909 encounters, 889 unique patients). There was a significant difference in 365-day reutilization pre- and postlockdown when analyzing re-presentation to the emergency department (P = .025) and hospital readmission (P = .006). Admissions incrementally increased after the COVID-19 alpha variants in September 2020 and again after the delta variant in August 2021.

CONCLUSIONS
The COVID-19 pandemic further intensified the already critical issue of pediatric mental health, demonstrating increased reutilization in the year after their initial presentation and an increase in admissions after the alpha variant.

Published: April 2024

AbstractBackground and aimsCompulsivity contributes to the development and maintenance of multiple addictive disorders. However, the relationship between compulsivity-related cognitive features and problematic usage of the internet (PUI), an umbrella term for various internet use disorders/interfering behaviors, remains largely unclear, partly due to the multidimensional nature of compulsivity. This scoping review utilized a four-domain framework of compulsivity to consider this topic and aimed to summarize available evidence on compulsivity-related neuropsychological characteristics in PUI based on this framework.MethodsA systematic literature search was conducted by applying the combination of search term to the search engines of PubMed, PsycINFO and Web of Science. A four-domain framework of compulsivity, involving cognitive flexibility, set-shifting, attentional bias, and habit learning, was used to consider its complex structure and frequently used tasks. Main findings in related PUI studies were summarized based on this framework. Our secondary aim was to compare compulsivity-related features between different PUI subtypes.ResultsThirty-four empirical studies were retained, comprising 41 task-results and 35 independent data sets. Overall, individuals with PUI showed more consistent deficits in attentional biases and were relatively intact in set-shifting. Few studies have examined cognitive flexibility and habit learning, and more evidence is thus needed to establish reliable conclusions. Moreover, most studies focused on internet gaming disorder, whereas other PUI sub-types were not sufficiently examined.ConclusionThis systematic review highlights the use of the four-domain framework for advancing understanding of mechanisms underlying compulsivity in PUI. Related therapeutic implications and future directions are discussed.
