Authors: Li Li , Nguyen Tuan Anh , Liang Li-Jung , Lin Chunqing , Pham Thang Hong , Nguyen Ha Thi Thanh , Kha Steven
Published: March 2023

Background

A chronic condition, drug addiction, requires long-term multipronged health care and treatment services. Community-based approaches can offer the advantages of managing integrated care along the care continuum and improving clinical outcomes. However, scant rigorous research focuses on sustainable, community-based care and service delivery.

Objective

This protocol describes a study aiming to develop and test an intervention that features the alliance of community health workers and family members to provide integrated support and individualized services and treatment for people who use drugs (PWUD) in community settings.

Methods

Based on the National Institute on Drug Abuse’s Seek-Test-Treat-Retain (STTR) framework, an intervention that provides training to community health workers will be developed and piloted before an intervention trial. Trained community health workers will conduct home visits and provide support for PWUD and their families. The intervention trial will be conducted in 3 regions in Vietnam, with 60 communities (named communes). These communes will be randomized to either an intervention or control condition. Intervention outcomes will be evaluated at baseline and at 3, 6, 9, and 12 months. The primary outcome measure is PWUD’s STTR fulfillment, consisting of multiple individual fulfillment indicators across 5 domains: Seek, Test, Treat, Retain, and Health. The secondary outcomes of interest are the community health workers’ service provision and family members’ support. The primary analysis will follow an intention-to-treat approach. Generalized mixed-effects regression models will be used to compare changes in the outcome measures from baseline between intervention and control conditions.

Results

During the first year of the project, we conducted formative studies, including in-depth interviews and focus groups, to identify service barriers and intervention strategies. The intervention and assessment pilots are scheduled in 2023 before commencing the trial. Reports based on the baseline data will be distributed in early 2024. The intervention outcome results will be available within 6 months of the final data collection date, that is, the main study findings are expected to be available in early 2026.

Conclusions

This study will inform the establishment of community health workers and family members alliance, a locally available infrastructure, to support addiction services and care for PWUD. The methodology, findings, and lessons learned are expected to shed light on the addiction service continuum’s implementation and demonstrate a community-based addiction service delivery model that can be transferable to other countries.

Factors Influencing the Clinical Adoption of Quantitative Gait Analysis Technologies for Adult Patient Populations With a Focus on Clinical Efficacy and Clinician Perspectives: Protocol for a Scoping Review (Preprint)
Authors: Sharma Yashoda , Cheung Lovisa , Patterson Kara K , Iaboni Andrea
Published: March 2023

BACKGROUND

Quantitative gait analysis can support clinical decision-making. These analyses can be performed using wearable sensors, nonwearable sensors, or a combination of both. However, to date, they have not been widely adopted in clinical practice. Technology adoption literature has highlighted the clinical efficacy of technology and the users’ perspective on the technology (eg, ease of use and usefulness) as some factors that influence their widespread adoption.

OBJECTIVE

To assist with the clinical adoption of quantitative gait technologies, this scoping review will synthesize the literature on their clinical efficacy and clinician perspectives on their use in the clinical care of adult patient populations.

METHODS

This scoping review protocol follows the Joanna Briggs Institute methodology for scoping reviews. The review will include both peer-reviewed and gray literature (ie, conference abstracts) regarding the clinical efficacy of quantitative gait technologies and clinician perspectives on their use in the clinical care of adult patient populations. A comprehensive search strategy was created in MEDLINE (Ovid), which was then translated to 4 other databases: CENTRAL (Ovid), Embase (Ovid), CINAHL (EBSCO), and SPORTDiscus (EBSCO). The title and abstract screening, full-text review, and data extraction of relevant articles will be performed independently by 2 reviewers, with a third reviewer involved to support the resolution of conflicts. Data will be analyzed using content analysis and summarized in tabular and diagram formats.

RESULTS

A search of relevant articles will be conducted in all 5 databases, and through hand-searching in Google Scholar and PEDro, including articles published up until December 2022. The research team plans to submit the final scoping review for publication in a peer-reviewed journal in 2023.

CONCLUSIONS

The findings of this review will be presented at clinical science conferences and published in a peer-reviewed journal. This review will inform future studies designed to develop, evaluate, or implement quantitative gait analysis technologies in clinical practice.

Published: March 2023

BACKGROUND

Clinical guidelines recommend regular serum lithium monitoring every 3 to 6 months. However, in the real world, only a minority of patients receive adequate monitoring.

OBJECTIVE

This study aims to examine whether the use of the electronic health record (EHR)–nested reminder system for serum lithium monitoring can help achieve serum lithium concentrations within the therapeutic range for patients on lithium maintenance therapy.

METHODS

We conducted an unblinded, single-center, EHR-nested, parallel-group, superiority randomized controlled trial comparing EHR-nested reminders with usual care in adult patients receiving lithium maintenance therapy for mood disorders. The primary outcome was the achievement of therapeutically appropriate serum lithium levels between 0.4 and 1.0 mEq/L at 18 months after enrollment. The key secondary outcomes are included as follows: the number of serum lithium level monitoring except for the first and final monitoring; exacerbation of the mood disorder during the study period, defined by hospitalization, increase in lithium dose, addition of antipsychotic drugs or mood stabilizers, or addition or increase of antidepressants; adherence defined by the proportion of days covered by lithium carbonate prescription during the study period.

RESULTS

A total of 111 patients were enrolled in this study. A total of 56 patients were assigned to the reminder group, and 55 patients were assigned to the usual care group. At the follow-up, 38 (69.1%) patients in the reminder group and 33 (60.0%) patients in the usual care group achieved the primary outcome (odds ratio 2.14, 95% CI 0.82-5.58, P=.12). The median number of serum lithium monitoring was 2 in the reminder group and 0 in the usual care group (rate ratio 3.62; 95% CI 2.47-5.29, P<.001). The exacerbation of mood disorders occurred in 17 (31.5%) patients in the reminder group and in 16 (34.8%) patients in the usual care group (odds ratio 0.97, 95% CI 0.42-2.28, P=.95).

CONCLUSIONS

We found insufficient evidence for an EHR-nested reminder to increase the achievement of therapeutic serum lithium concentrations. However, the number of monitoring increased with relatively simple and inexpensive intervention. The EHR-based reminders may be useful to improve quality of care for patients on lithium maintenance therapy, and they have potentials to be applied to other problems.

Digital Cognitive Assessment Tests for Older Adults: Systematic Literature Review (Preprint)
Authors: Cubillos Claudio , Rienzo Antonio
Published: March 2023

BACKGROUND

The global health pandemic has affected the increasing older adult population, especially those with mental illnesses. It is necessary to prevent cases of cognitive impairment in adults early on, and this requires the support of information and communication technologies for evaluating and training cognitive functions. This can be achieved through computer applications designed for cognitive assessment.

OBJECTIVE

In this review, we aimed to assess the state of the art of the current platforms and digital test applications for cognitive evaluation, with a focus on older adults.

METHODS

A systematic literature search was conducted on 3 databases (Web of Science, PubMed, and Scopus) to retrieve recent articles on the applications of digital tests for cognitive assessment and analyze them based on the methodology used. Four research questions were considered. Through the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology, following the application of inclusion and exclusion criteria, a total of 20 articles were finally reviewed.

RESULTS

Some gaps and trends were identified regarding the types of digital applications and technologies used, the evaluated effects on cognitive domains, and the psychometric parameters and personal characteristics considered for validation.

CONCLUSIONS

Computerized tests (similar to paper-and-pencil tests) and test batteries (on computers, tablets, or web platforms) were the predominant types of assessments. Initial studies with simulators, virtual environments, and daily-life activity games were also conducted. Diverse validation methods and psychometric properties were observed; however, there was a lack of evaluations that involved specific populations with diverse education levels, cultures, and degrees of technology acceptance. In addition, these evaluations should consider emotional and usability aspects.
Counter- Representational Discourse of Islam in Islamophobic States: The Case of Mohja Kahf’s The Girl in Tangerine Scarf (2006)
Authors: Houssine Khadiri El
Published: March 2023

Anglophone Arab literature in general and women in specific witnessed unprecedented change in content and quantity after the Twin Tower collapse. The September attacks of the 2011 brought about great political, social, cultural changes to the situation of Arabs in the West and America in particular since it destabilized their sense of belonging and created an agony and hostility against them. The experiences of social, political, and cultural marginality shape Arab Women’s diaspora fiction which, in turn, attempts to produce a rhetoric of resistance to counter-balance discourses of hierarchies and cultural binaries (self/other, black/white man woman and so forth). In this respect, The Girl in the Tangerine Scarf (2006), written by Arab American, Mohja Kahf, functions as a mirror which reflects on the image of Islam, the veil and Arab-Muslim identities in Islamophobic states. This paper, therefore, offers an investigation of how, in border zone, Mohja Kahf attempts to correct the fallacies vis-à-vis Islam and Muslim and negotiates journeys of displacement and dislocation that Arab immigrants may experience.
políticas de educación superior en Venezuela
Authors: Parra-Sandoval María Cristina
Published: March 2023

En Venezuela, la década de los noventa fue de pocas realizaciones en respuesta a los cambios exigidos a la educación superior, y en especial a la universidad. Con el advenimiento de un gobierno que se califica a sí mismo de revolucionario se han producido cambios en las políticas públicas en educación superior. Sus objetivos, propuestos para superar los rezagos y las carencias anteriores, pueden resumirse básicamente en tres: lucha contra la exclusión y logro de la equidad; pertinencia social y calidad. En su implementación ha prevalecido un enfoque ideológico-político, evidenciado en programas como la Misión Sucre y la Universidad Bolivariana, lo cual plantea varias interrogantes en torno a sus implicaciones para el logro de la calidad de la educación y el reconocimiento de la libertad académica consustancial a la universidad como institución en la cual debe prevalecer la independencia de cualquier forma de poder que pretenda controlar su proceso creativo.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Yeon Eun Mo , Choi Hyosik
Published: March 2023

Objectives This study was conducted to explore the trajectory of changes in academic self-efficacy from 7th to 12th graders and analyzed the concurrent and lagged effects of relationships with parenting style, attachment, and understanding instructions. Methods Six waves (Grades 7~12; N=3,952) of data from Gyeonggi Education Panel Study (GEPS) were analyzed using latent growth modeling (LGM). Results Results were as follows: First, academic self-efficacy decreased over time for 6 years. Second, while the concurrent and lagged effects of monitoring, reasonable parenting behavior, and trust from parents increased academic self-efficacy, isolation from parents decreased academic self-efficacy over time. Third, understanding instructions of students had concurrent and lagged effects on academic self-efficacy during 7th to 12th years. Conclusions The present findings suggest that increasing understanding instruction would be the most effective factor to increase academic self-efficacy during 7th to 12th grades. The results also imply that parenting style and attachment with parents closely related with academic self-efficacy of adolescents.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Min Seong , Kim Eun Jung
Published: March 2023

Objectives The present study investigated whether self-concealment and Entrapment would mediate the relationship between Internalized shame and Suicidal ideation among college students. Methods Subjects were 325 college students who were asked to complete self-report questionnaires to assess internalized shame, self-concealment, entrapment and suicidal ideation. Structural Equation Modeling(SEM) analysis was performed using AMOS 22.0. Results First, entrapment mediated the relationship between internalized shame and suicidal ideation. Second, self-concealment has not mediated the relationship between internalized shame and suicidal ideation. Finally, the relationship between internalized shame and suicidal ideation was sequentially mediated by self-concealment and entrapment. Conclusions These results suggest that internalized shame can make more self-concealment and entrapment, and in turn it draws to more suicidal ideation.

A Syntactic & Semantic Analysis on ‘ida’ sentence with the meaning of ‘existence’ in Korean
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Zhang Lei
Published: March 2023

Objectives In this study, it aims to identify the ‘ida’ sentence with the meaning of ‘existence’ and to explore their structural and semantic features based on the actual corpus. Methods Firstly, using actual corpus data such as the Sejong Corpus and the SJ-RIKS Corpus, we retrieved use instances of the ‘ida’ sentence with the meaning of ‘existence’; Secondly, analyzed the structural types and constituent elements of the ‘ida’ sentence with the meaning of ‘existence’; Thirdly, the semantic features of the NP of the ‘ida’ sentence with the meaning of ‘existence’ are examined through a comparison with the ‘itta’ existence sentence; Finally, based on subjective theory and starting from the prototypical meaning of the ‘ita’ sentence, an explanation of the semantic features is offered. Results The results show that, Firstly, the basic structure of the ‘ida’ sentence with the meaning of ‘existence’ is ‘NPL+NP+ida’ and the sentence structure can be summarized into three types. Among them, there can be concrete and abstract places in the NPL position, and there are also vacancies. In the NP position, not only can there be specific living people or inanimate objects, but events and abstract thinking activities and emotions can appear as well; Secondly, by replacing ‘ida’ sentence with the meaning of ‘existence’ with the ‘itta’ existence sentence, it is concluded that the NP of the ‘ida’ sentence with the meaning of ‘existence’ has the features of [+sufficiency], [+uniqueness], and [+prominence]; Thirdly, the motivation behind the ‘ida’ sentence with the meaning of ‘existence’ with the above semantic features is that the speaker's subjective view that NPL and NP is equivalent identity. Conclusions This study examines the structure and semantic features of the ‘ida’ sentence with the meaning of ‘existence’. Although there are many shortcomings, I believe that this study has implications for the semantic study of copular sentences and the semantic category of Korean ‘existence’.

Published: March 2023

Objectives The purpose of this study was to investigate the effects of multidimensional perfectionism and lethargy tendency on parenting stress in working mothers with infants and toddlers, and to verify the mediating effect of emotional change. Methods In September 2021, 312 working mothers with infants and young children were surveyed using the multidimensional perfectionism scale, helplessness scale, parenting stress scale, and emotional relief scale. Results were derived from the collected data through correlation analysis, regression analysis, Baron & Kenny's 3-step mediating effect analysis, and bootstrapping. Results First, working mothers' multidimensional perfectionism was found to be significantly correlated with parenting stress, and among the sub-factors of multidimensional perfectionism, only socially imposed perfectionism was found to be significantly correlated with parenting stress. Second, helplessness of working mothers was found to be significantly correlated with parenting stress. Third, in the effect of social imposition perfectionism, a sub-factor of multidimensional perfectionism, on parenting stress, emotional hunger was found to be completely mediated. Fourth, in the effect of helplessness of working mothers on parenting stress, emotional ups and downs were found to have a partial mediation. Conclusions From the above results, it can be seen that counseling intervention and parenting education should be conducted according to the personality characteristics and emotional situation of mothers who complain of parenting stress in counseling and clinical aspects.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kwon Ji Woo , Park Yoon Suh , Kim Dae Kwon
Published: March 2023

Objectives This study analyzed the importance and performance of good instruction recognized by students studying Educational Methods in graduate school of Education. Methods We conducted an online survey of 62 graduate students majoring in Educational methods from nine universities. We asked the respondents to rate the importance of the factors of five major categories determining good instruction: philosophy, direction, method, course management and the instructor’s attitude and style. They were also asked to rate the performance of the factors based on their perception of how well those factors are actually manifested in courses. Results First, the respondents recognized the philosophy and method as the most important factor, while course management was recognized as the least important. The performance level was perceived as high in instructor’s attitude and style and philosophy, while low in method. Second, the difference between the average of perceived importance and their performance level was statistically significant in all areas. Specifically, method showed the greatest difference. Third, philosophy showed a high level of perceived importance and performance. The importance of method and direction was perceived to be low, while the performance of those factors was perceived to be high. The levels of importance and performance were both low in course management, and instructor’s attitude and style show a low importance level but was demonstrated to have high performance level. Conclusions The graduate schools of Education should offer courses based on a clear understanding of course objectives. In addition, the philosophy of the courses should be maintained to pique students’ intellectual interests, inspiration and satisfaction. Moreover, graduate schools should encourage the students to discover the importance of course management. Finally, we need a more diverse array of courses using practical and effective educational methods.

Formation of pure anatase TiO2 by reactive pulsed dc magnetron sputtering: method for controlling target poisoning state
Authors: Desch Nikolai , Lake Markus
Published: March 2023

The use of pulsed dc-sputtering sources for reactive magnetron
sputtering with oxygen offers a possibility to suppress the negative
effects of target poisoning (such as arcing). This results in a wide
process range for the selection of a desired operating point. The
control of target poisoning plays a major role in maintaining constant
coating properties and affects the stoichiometry of the reactive
coating, as well as the coating rate and the economic impact of the
coating process. In a hysteresis, the target poisoning during the
reactive sputtering of titanium under oxygen addition proceeds
nonlinearly. Without the use of a suitable target poisoning control
technique, the sputtering process can abruptly change to an unstable
state. As a result, variations of stoichiometry can occur during the
deposition process. A proven method for maintaining a stable reactive
sputtering process is the control of oxygen flow with the input variable
target voltage. By determining the typical oxygen hysteresis at constant
target power and constant argon flow, an operating point for the control
loop is derived. The desired target voltage then serves as the input
variable for the control loop of the target poisoning. The controlling
technique for target poisoning is a basic requirement for the production
of the photolytic active anatase phase of titanium dioxide
(TiO) using reactive magnetron sputtering. The
photocatalytic equipment of surfaces with a titanium dioxide coating in
the anatase phase can be realized with the reactive pulsed dc magnetron
sputter ion plating process (DC-MSIP). The pulsed DC-MSIP process
facilitates coating a variety of surfaces at temperatures below 200 °C
in an environmentally friendly manner.
Deciphering the broccoli plants response to salinity and boron stress on with a focus on membranes and aquaporins
Authors: Carvajal Micaela , Nicolas-Espinosa Juan , Yepes Lucia , Martinez-Bernal Fuensanta , Fernandez-Pozurama Miriam
Published: March 2023

Abiotic stresses as salinity, and boron toxicity, and deficiency are
commonly found in arid and semi-arid areas were broccoli is abundantly
grown. In this work, the physiological response of broccoli leaves
(including growth, relative water content, stomatal conductance, and
mineral concentration) was studied under salinity and boron stresses
(deficiency and toxicity), individually or in combination. Also, the
molecular study of PIP aquaporins were studied in relation to their
presence in plasma membrane PIP presence and their membrane lipid
environment. The results showed that only the combination of salinity
and boron deficiency decreased plant biomass, suggesting good adaptation
to the other treatments. Changes in stomatal conductance and mineral
nutrients suggest that the adaptation was related to water and boron
transport through leaves, involving aquaporins since avoidance strategy
was observed. Furthermore, changes in aquaporins PIP expression revealed
that each individual aquaporin is involved in each treatment, either
alone or in combination. However, the discrepancy between the presence
of aquaporins in the plasma membrane and microsomal fraction pointed
towards the regulation of trafficking and membrane composition (lipids
and proteins) should be highly present in this plant under stress.

local approximation theorem, Voronovskaja type asymptotic formula, bound for
the second central moment with some curtailment, and the global
approximation theorem by means of modulus of continuity and the
Ditzian-Totik Modulus of smoothness. We also study the difference estimates
between Stancu-Bernstein operators and its Kantorovich variant. Further, we
show the convergence of these operators by graphics to certain functions.

Published: March 2023

We investigate the distribution of zeros of all solutions of a non-autonomous nonlinear neutral differential equation that generalizes a lossless transmission network model. The neutral term is taken to be positive. We give several new estimations of the gap between adjacent zeros. The obtained results are supported by illustrative examples.
Braided Galois objects and Sweedler cohomology of certain Radford biproducts
Authors: Femic Bojana
Published: March 2023

We construct the group of H-Galois objects for a flat and cocommutative Hopf algebra in a braided monoidal category with equalizers provided that a certain assumption on the braiding is fulfilled. We show that it is a subgroup of the group of BiGalois objects of Schauenburg, and prove that the latter group is isomorphic to the semidirect product of the group of Hopf automorphisms of H and the group of H-Galois objects. Dropping the assumption on the braiding, we construct the group of H-Galois objects with normal basis. For H cocommutative we construct Sweedler cohomology and prove that the second cohomology group is isomorphic to the group of H-Galois objects with normal basis. We construct the Picard group of invertible H-comodules for a flat and cocommutative Hopf algebra H. We show that every H-Galois object is an invertible H-comodule, yielding a group morphism from the group of H-Galois objects to the Picard group of H. A short exact sequence is constructed relating the second cohomology group and the two latter groups, under the above mentioned assumption on the braiding. We show how our constructions generalize some results for modules over commutative rings, and some other known for symmetric monoidal categories. Examples of Hopf algebras are discussed for which we compute the second cohomology group and the group of Galois objects.

The removal of copper ions from aqueous solutions using bean shells as an adsorbent is presented in this paper. The influence of the solution pH on the biosorption capacity was investigated. The biosorption capacity increased with the increase in the solution pH. The pseudo-second order kinetic model showed the best agreement with the analysed experimental data, indicating that chemisorption could be a possible way of binding the copper ions to the surface of the bean shells. The Langmuir isotherm model best fitted the analysed isotherm data. The SEM-EDS analysis was performed before and after the biosorption process. The change in the morphology of the sample after the biosorption process was evident, whereby K, Mg, Si and Ca were possibly exchanged with copper ions. Response surface methodology (RSM) based on the Box?Behnken design (BBD) was used to optimize the biosorption process, with the selected factors: the solution pH, initial copper ions concentration and contact time. The optimum biosorption conditions were determined to be: pH 3?4, initial copper ions concentration, 100 mg dm-3, and contact time, 10?30 min.

Introduction/Objective. Gilbert syndrome (GS) is the most common hereditary hyperbilirubinemia. As well as mild unconjugated hyperbilirubinemia, it is characterized by the excess of bilirubin monoglucuronide over diglucuronide in the bile and thus increases the risk of biliary calculosis. The aim of the study was to determine the importance of GS as a risk factor in the development of cholelithiasis in children. Methods. The study included a sample of 31 children (14 male and 17 female, mean age 12.16 ? 4.11 years, range 3?16.75 years) with symptomatic cholelithiasis. The diagnosis of cholelithiasis was based on an ultrasonographic finding, and for GS the diagnosis was based on at least a double increase of unconjugated bilirubin fraction after a three-day hypocaloric diet (400 kcal per day). Results. GS was confirmed in five or 16.13% of patients (three male and two female, mean age 14.71 ? 0.55 years, range 14?15.3 years). In addition to GS, in the history of the disease they all had some of the additional risk factors for the development of cholelithiasis. One of them had an identical problem as its mother, one had hereditary elliptocytosis, one had sudden weight loss, one was overweight, and one had premature birth and sepsis. Conclusion. GS registers in one-sixth of children with cholelithiasis, but in none of them as the only risk factor for developing this disease. This finding suggests that GS is a risk factor for the development of cholelithiasis, but not sufficient in itself in that respect.

Intra-hepatic islet transplantation for type-1 diabetes is limited by the need for multiple infusions and poor islet viability post-transplantation. The development of alternative transplantation sites is necessary to improve islet survival, and facilitate monitoring and retrieval. We tested a clinically proven Biodegradable Temporizing Matrix (BTM), a polyurethane-based scaffold, to generate a well vascularized intracutaneous ‘neo-dermis’ within the skin for islet transplantation.  In murine models, BTM did not impair syngeneic islet renal-subcapsular transplant viability or function, and facilitated diabetes cure for over 150 days. Further, BTM supported functional neonatal porcine islet transplants into RAG-1-/- mice for 400 days. Hence, BTM is non-toxic for islets. two-photon intravital imaging used to map vessel growth through time identified dense vascular networks, with significant collagen deposition and increases in vessel mass up to 30 days post-BTM implantation. In a pre-clinical porcine skin model, BTM implants created a highly-vascularized intracutaneous site by day 7 post-implantation. When syngeneic neonatal porcine islets were transplanted intracutaneously the islets remained differentiated as insulin producing cells, maintained normal islet architecture, secreted c-peptide, and survived for over 100 days. Here we show that BTM facilitates formation of an islet-supportive intracutaneous ‘neo-dermis’ in a porcine pre-clinical model, as an alternative islet transplant site.
