Published: March 2023

Atopic dermatitis is a chronic inflammatory skin disease characterized by a recurrent course, difficulty in individual selection of therapy, especially in patients with severe course. When examining and treating such patients, one of the routine diagnostic methods is to determine the level of total immunoglobulin E in the blood serum. The article is devoted to the analysis of available world practice data on published clinical cases of the use of biological therapy with dupilumab in real clinical practice in patients with severe atopic dermatitis, in whom high and very high levels of immunoglobulin E. The appointment of biological therapy for this cohort of patients often raises significant concerns. However, the use of a monoclonal antibody against IL-4/IL-13 proved effective, did not lead to serious adverse reactions in such patients and was accompanied by a decrease in the level of immunoglobulin E during treatment. It was noted that immunosuppressive treatment prior to biological therapy led to the development of adverse events in these patients. A separate group of patients with genetically determined hyper-IgE syndrome and severe atopic dermatitis is described, in which the positive experience of using dupilumab is also noted. The author presents his own clinical case of a patient with severe atopic dermatitis and a high level of immunoglobulin E receiving successful targeted therapy after a preliminary thorough examination except for lymphoproliferative and autoimmune diseases. Against the background of dupilumab therapy, there was a pronounced clinical regression of skin symptoms, a decrease in the level of immunoglobulin E, an increase in the patient’s quality of life, and the absence of side effects.

Authors: CANPOLAT Sinem , SÜNKÜR ÇAKMAK Meltem
Published: March 2023

Introduction: The purpose of this study is to find the effect of working conditions of special education teachers, who work in general education schools, on the work alienation levels. The issues that differentiate the working conditions of special education classes from others are various special conditions, such as the way break times are used, the requirement to have two teachers in a class and the needs to have special physical materials and arrangements.
Method: Phenomenology pattern, one of qualitative research methods, was used in the study. Study data were collected through semi-structured interview technique and the data were analyzed through descriptive analysis technique. 20 special education teachers working in the city center of Diyarbakır during 2019-2020 academic year participated in the study. The study group was determined through snowball and criterion sampling methods.
Findings: When the study findings were examined, it was found that the teachers have intensive amount of work alienation. It can be claimed that special education teachers are experiencing alienation in isolation level at most and senselessness level at least. It was concluded that working conditions have an effect on work alienation of special education teachers.
Discussion: It is understood that special education teachers feel themselves unhappy, alone and isolated in the organizations they work, they are required to work in an environment, where no one understands them, they believe that they will not receive the support they need from their managers, they experience a conflict of authority within the class and they have problems in following the rules of organization. Thus, it was found that they experience many symptoms of work alienation. It is recommended to hire supporting staff to takeover the responsibility of care of students from these teachers and ensure that special education teachers work under the same conditions with their colleagues.

Published: March 2023

Multiple potential drugs have been developed based on the heterocyclic molecules for
the treatment of different symptoms. Among the existing heterocyclic molecules, quinazoline and
quinazolinone derivatives have been found to exhibit extensive pharmacological and biological
characteristics. One significant property of these molecules is their potency as anti-tubercular
agents. Thus, both quinazoline and quinazolinone derivatives are modified using different functional
groups as substituents for investigating their anti-tubercular activities. We present a summary
of the reported anti-tubercular drugs, designed using quinazoline and quinazolinone derivatives,
in this review.

Authors: Moftakhar Arya , Khoshnam Seyed Esmaeil , Farzaneh Maryam
Published: March 2023

Brain cancers or intracranial cancers are among the deadliest cancers in the world. The
presence of tumorigenic cancer cells in the brain and induction of poor prognosis may impact the
survival/death balance. Glioma is a type of brain tumor that begins in the glial tissue. Recently, it has
been reported that long non-coding RNAs (lncRNAs) with at least 200 nucleotides in length by targeting
DNAs, RNAs, and proteins play essential roles in several biological processes, including
growth, differentiation, and development. Recently, lncRNAs was reported to contribute to the tumorigenesis
of glioma by targeting miRNAs, other ncRNAs, and mRNAs. In this review, we focused
on the functional roles of lnRNAs in glioma.

Hypertrophic cardiomyopathy (HCM), now recognized as a common cardiomyopathy of
complex genomics and pathophysiology, is defined by the presence of left ventricular hypertrophy
of various morphologies and severity, significant hemodynamic consequences, and diverse phenotypic,
both structural and clinical, profiles. Advancements in cardiac multimodality imaging, including
echocardiography, cardiac magnetic resonance imaging, and cardiac computed tomography,
with and without angiography have greatly improved the diagnosis of HCM, and enable precise
measurements of cardiac mass, volume, wall thickness, function, and physiology. Multimodality
imaging provides comprehensive and complementary information and hasemerged as the bedrock
for the diagnosis, clinical assessment, serial monitoring, and sudden cardiac death risk stratification
of patients with HCM. This review highlights the role of cardiac multimodality imaging in
the modern diagnosis and management of HCM.
Investigating Reciprocity Dynamics in Chinese SOEs: Contextual Impacts on Social Support, HRM Practices, and Employee Attitudes Toward Organizational Change
Authors: Fan Yang , Li Yanju , Johnson Nathan
Published: March 2023

This study aims to investigate the relationship between employee attitudes toward organizational change, human resource management (HRM) practices, and social support in Chinese State-owned enterprises (SOEs). It also explores how the SOEs context impacts the above relationships. Quantitative research was conducted using 143 participants from Chinese SOEs. A hierarchical regression model was built to test how social support and HRM practices impact employee attitudes toward organizational change. The results indicate that social support and most HRM practices in SOEs are not statistically significant predictors of an employee’s positive attitude. This finding suggests that contextual influences of SOEs limit the effectiveness of HRM practices. This research contributes to our understanding of the Chinese government’s impact on employee attitudes in SOEs and the complexity of multi-party reciprocity dynamics.
The Mediating Effect of Trust on Psychological Safety and Job Satisfaction
Authors: Mitterer Dennis M. , Mitterer Heather E.
Published: March 2023

This research aims to assess the relationship of psychological safety and trust on employee job satisfaction. Individual job satisfaction is essential to personal and professional accomplishments, impacting team success, and achieving optimal organizational performance. A safe environment is a critical factor to achieve job satisfaction. When employees feel safe, learning occurs more quickly, peers rely on each other, and team performance improves. Trust in peers and management influences psychological safety development. Therefore, understanding the role of psychological safety and trust in the development of engaged employees is essential. In this paper, we approach the idea that psychological safety is a prerequisite to trust, and we believe trust mediates the relationship between psychological safety and job satisfaction. A quantitative approach using correlation and mediation tested the theory of the effect trust has on psychological safety and job satisfaction. Responses from 283 nurses at a large teaching hospital revealed that psychological safety is linked to job satisfaction and mediated by trust. Overall, this study suggests that psychological safety precedes trust and collectively increases individual job satisfaction. Managers can draw upon the potential, but frequently untapped benefits, of cultivating a safe space by developing a sincere and trusting relationship with employee-partners thus increasing job satisfaction.

Authors: Feng Yuheng , Zhao Yuxi , Mao Linqi , Gu Minmin , Yuan Hong , Lu Jun , Zhang Qi , Zhao Qian , Li Xiaohong
Published: March 2023

Background

Intervention based on family support and risk perception can enhance type 2 diabetes mellitus (T2DM) patients’ self-care activities. In addition, eHealth education is considered to improve family members’ support for patients with T2DM. However, there is little evidence from rigorously designed studies on the effectiveness of an intervention combining these approaches.

Objective

This randomized controlled trial (RCT) aimed to assess the effectiveness of an eHealth family-based health education intervention for patients with T2DM to improve their glucose control, risk perception, and self-care behaviors.

Methods

This single-center, 2-parallel-group RCT was conducted between 2019 and 2020. Overall, 228 patients were recruited from Jiading District, Shanghai, and randomly divided into intervention and control groups. The intervention group received an eHealth family intervention based on community management via WeChat, whereas the control group received usual care. The primary outcome was the glycated hemoglobin (HbA1c) level of the patients with T2DM, and the secondary outcomes were self-management behavior (general and specific diet, exercise, blood sugar testing, foot care, and smoking), risk perception (risk knowledge, personal control, worry, optimism bias, and personal risk), and family support (supportive and nonsupportive behaviors). A 2-tailed paired-sample t test was used to compare the participants at baseline and follow-up within the control and intervention groups. An analysis of covariance was used to measure the intervention effect.

Results

In total, 225 patients with T2DM were followed up for 1 year. After intervention, they had significantly lower HbA1c values (β=–.69, 95% CI –0.99 to –0.39; P<.001). They also had improved general diet (β=.60, 95% CI 0.20 to 1.00; P=.003), special diet (β=.71, 95% CI 0.34 to 1.09; P<.001), blood sugar testing (β=.50, 95% CI 0.02 to 0.98; P=.04), foot care (β=1.82, 95% CI 1.23 to 2.42; P<.001), risk knowledge (β=.89, 95% CI 0.55 to 1.24; P<.001), personal control (β=.22, 95% CI 0.12 to 0.32; P<.001), worry (β=.24, 95% CI 0.10 to 0.39; P=.001), optimism bias (β=.26, 95% CI 0.09 to 0.43; P=.003), and supportive behaviors (β=5.52, 95% CI 4.03 to 7.01; P<.001).

Conclusions

The eHealth family-based intervention improved glucose control and self-care activities among patients with T2DM by aiding the implementation of interventions to improve T2DM risk perceptions among family members. The intervention is generalizable for patients with T2DM using health management systems in community health centers.

Authors: Tam Hon Lon , Chair Sek Ying , Leung Isaac Sze Him , Leung Leona Yuen Ling , Chan Alex Siu Wing
Published: March 2023

Background

Practicing healthy lifestyles can reduce the risk to develop noncommunicable diseases and the related mortality. Studies showed that practicing healthy lifestyles could enhance disease-free life expectancy and preserve bodily functions. However, engagement in healthy lifestyle behavior was suboptimal.

Objective

This study aimed to define individuals’ lifestyle characteristics before and during COVID-19 and determine the factors associated with practicing a healthy lifestyle. This cross-sectional study was conducted using data from the 2019 and 2021 Behavioral Risk Factor Surveillance System surveys.

Methods

US individuals aged ≥18 years were interviewed via phone call. Healthy lifestyles were assessed through corresponding questions regarding the maintenance of optimal body weight, physical activity, daily consumption of at least five portions of fruits and vegetables, current smoking status, and alcohol consumption. Missing data were imputed using a package in the R statistical software. The effects of practicing a healthy lifestyle on cases without missing data and those with imputation were reported.

Results

There were 550,607 respondents (272,543 and 278,064 from 2019 and 2021, respectively) included in this analysis. The rates of practicing a healthy lifestyle were 4% (10,955/272,543) and 3.6% (10,139/278,064) in 2019 and 2021, respectively. Although 36.6% (160,629/438,693) of all 2021 respondents had missing data, the results of the logistic regression analysis for cases without missing data and those with imputation were similar. Of the cases with imputation, women (odds ratio [OR] 1.87) residing in urban areas (OR 1.24) with high education levels (OR 1.73) and good or better health status (OR 1.59) were more likely to practice healthier lifestyles than young individuals (OR 0.51-0.67) with a low household income (OR 0.74-0.78) and chronic health conditions (OR 0.48-0.74).

Conclusions

A healthy lifestyle should be strongly promoted at the community level. In particular, factors associated with a low rate of practice of healthy lifestyles should be targeted.

Authors: Jung Timothy , Cho Justin , Shekhawat Satpal Singh , Amin Muhammad Farhan
Published: March 2023

BACKGROUND

The uptake and completion rates for traditional pulmonary rehabilitation programs for patients with chronic obstructive pulmonary disease are low. A recent study using a newly developed Pulmonary rehabilitation in Virtual Reality (“PRinVR”) program has shown an increase in these rates, as well as significant improvements in both physical and psychological well-being. However, further research with a larger sample size must be conducted to confirm the positive effects of using VR in pulmonary rehabilitation.

OBJECTIVE

This paper aims to further assess the effectiveness of a novel Virtual Reality pulmonary rehabilitation intervention (“PRinVR”) for patients with chronic obstructive pulmonary disease, with a specific focus on compliance with the intervention, improvements to physical health, and improvements to mental health.

METHODS

A total of 140 patients from various GP surgeries in North Lincolnshire and completed the PRinVR program over the course of 24 months (March 2020-March 2022). Quantitative data were recorded in the form of self-report surveys before and after completing PRinVR. Further quantitative data on a 1-minute sit-to-stand test (1M-STS) was also recorded. The 3 self-report surveys include the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-9), and the Chronic Obstructive Pulmonary Disease Assessment Test (CAT).

RESULTS

An 85% compliance rate was recorded. The CAT and 1M-STS measuring physical recovery demonstrated major improvements to physical health (52.71% and 76.19% respectively). The GAD-7 and PHQ-9 measuring mental health also showed that over half of patients saw improvements (50.46% and 57.00% respectively).

CONCLUSIONS

This paper has provided further evidence on the effectiveness of PRinVR in improving compliance, physical health, and psychological health.
A Comparison of Contemporary Filial Piety in Rural and Non-Rural China and Taiwan
Authors: Ping Su Li , B Miller Richard
Published: March 2023

Research has found that filial piety remains strong in Chinese societies, despite dramatic social and economic changes. However, little is known about differences in filial piety between rural and nonrural regions of China and Taiwan, as well as gender differences in filial piety. Using data from the 2006 East Asia Social Survey, results indicated that there were no differences in attitudes about filial piety and attitudes of financial support between rural and nonrural regions in China and Taiwan, as well between adult men and women. Caregiving for elderly parents was more common in rural China, compared to nonrural China, and men in rural China were more likely to be engaged than rural women in caregiving. There were no other differences in reports of caregiving. Overall, the results suggest a lessening of gender differences and rural vs. nonrural differences in filial piety in China and Taiwan.

Authors: MD SARFARAZ , KUMAR SUSHIL , DODDAYYA H.
Published: March 2023

Objective: The objective of present research work was to fabricate and evaluate mouth-dissolving films of domperidone by solvent casting method using hydroxypropyl methyl cellulose as polymer for rapid release of drug.

Methods: Domperidone (DMP) is specific blocker of dopamine receptors (D2 and D3) and is widely used to treat emesis. Since domperidone solubility is less, domperidone solid dispersion (DMP SD’s) were prepared with β-cyclodextrine inclusion complexes in different ratio (1:1, 1:2, 1:3 and 1:4) by kneading method to increase the solubility. The DMP mouth dissolving films (MDF) were developed using DMP SD’s by solvent casting method. Hydroxypropyl methyl cellulose (HPMC) was used as film forming agent and glycerine was used as plasticizer. Nine formulations were fabricated and were evaluated for their various physico-mechanical properties, in vitro disintegration time and in vitro dissolution characteristics.

Results: The solid dispersion SD3 increased the solubility of drug compared to pure drug. FTIR studies revealed the integrity of the drug in its pure form in both drug-βcyclodextrine complex and finished MDF. The thickness uniformity, weight uniformity, folding endurance, surface pH and drug content of mouth dissolving films were uniform and reproducible. Formulation F1 released highest percentage of drug i.e., 100% of drug in 16 min compared to other formulations in in vitro release studies and disintegrated within 2.5 min and hence was considered as optimized formulation. The mechanism of drug release of prepared mouth dissolving films was Non-Fickian diffusion controlled kinetics.

Conclusion: Complexation by Kneading technique was found satisfactory for solid dispersion of domperidone. Solvent casting method was successfully used to obtain uniform mouth dissolving films containing drug-β cyclodextrine solid dispersion. Mouth dissolving films containing domperidone could be successfully developed and optimised.

Published: March 2023

In the face of climate change, the optimization of crop diversification policy in Côte d'Ivoire must go through research and promotion of crops of interest that require little water, including Aloe vera. However, in view of its slow growth in nursery, the improvement of growth substrate fertility by the supply of nutrients is necessary. Thus, this study aims at assessing the effects of six organic matter formulations on Aloe vera growth in nursery. To this end, a completely randomized block experimental design comprising six treatments and three replications was carried out. The amendments tested were cow dung, chicken droppings, charcoal, banana tree stems and ripe plantain and dessert bananas. The results showed substrate pH variability (6.67 to 7.87) depending on the amendments. Leaf emergence speed increased with cow dung from the 80th day after planting. Similarly, the highest number of leaves was obtained with cow dung (9.33 leaves). With 22.89 cm in average length and 1.65 cm in average width, the leaves generated with cow dung were also the longest and widest. This study showed that cow dung promotes rapid Aloe vera growth in nursery.

Authors: Blanco Tapia Sergio , Jauregui Paravicini Lorena , Carvajal Tapia Aarón Eduardo
Published: March 2023

The trichobezoar is a variety of bezoars whose characteristic is the presence of a compact mass made up of indigestible material, mainly hair and other components. Presentation of cases: We present 2 cases of patients aged 4 and 9 years, who were admitted to an emergency room, with symptoms of chronic evolution characterized by a palpable abdominal mass, progressive weight loss associated with trichophagia-trichotillomania, with presumed diagnosis of gastric bezoar admission. The abdominal ultrasound in both reported an echorefringent image inside that produces an acoustic shadow, compatible with a probable trichobezoar, a diagnosis reinforced by contrast-enhanced computed tomography. Given the impossibility of endoscopic extraction due to the large size, it was decided to perform exploratory laparotomy, extracting the complete en-bloc mass through a gastrotomy in both cases. The patients presented a favorable evolution, receiving parenteral feeding for 5 days and then oral ingestion with good tolerance, being discharged from hospital on their 9th and 10th postoperative day with interdisciplinary follow-up and psychological support. There is a high suspicion of trichobezoar in the presence of trichotillomania, affective compromise, psychomotor retardation, intestinal symptoms and postsurgical neuropsychiatric management is essential in order to reduce the risk of recurrence. Keywords: Bezoars; trichotillomania; gastrointestinal diseases.

Published: March 2023

Abstract: Unmanned Aerial Vehicles (UAV) is in constant development since First World War. As the technology became complex and compact, the UAVs are also being utilized for commercial purposes. The main purpose of a UAV was for scouting, to perform certain operations in remote areas with minimal human interference and to eliminate the risk of human pilots. UAVs are classified based on their weight, range of operation, type of model, and fuel consumption. At present, multi-rotor drones with high mobility are widely used for commercial sectors especially, aerial photography, sports, surveys, etc. Most of the drones are electric-based which provide a maximum of 30 minutes flight time that is sufficient for small scale applications. There are combustible fuel based drones in development, but they are very expensive, also multi-rotor drones are inefficient and provide less output per input.

Published: March 2023

We present benchmarks of the parity transformation for the Quantum Approximate Optimization Algorithm (QAOA). We analyse the gate resources required to implement a single QAOA cycle for real-world scenarios. In particular, we consider random spin models with higher order terms, as well as the problems of predicting financial crashes and finding the ground states of electronic structure Hamiltonians. For the spin models studied our findings imply a significant advantage of the parity mapping compared to the standard gate model. In combination with full parallelizability of gates this has the potential to boost the race for demonstrating quantum advantage.

Энэхүү ажлаар Тайланд улсын ТРР-1/М1 судалгааны реакторыг 1.2 МВт, 1.5 МВт, 2.0 МВт тогтвортой чадалтай ажиллаж байх тохиолдлуудад реактивитийн өөрчлөлтийг судлав. Эдгээр тохиолдолд реактивитийг 0.5 $, 1.0 $ гэж сонгон авч реакторын чадал, түлшний дундаж температур, реактивитийн хамаарлыг EUREKA-2RR код ашиглан тооцоолов. Энэ реакторынчадал нь импульсын горимд 2000 МВт хүрдэг. Реакторын голомтоос шарагдаж байгаа дээжийг сугалахад үүсэх реактивитийн хамгийн их утга 1.0 $ байхад реакторын чадал 18.1 МВт болж байна. Энэ нь импульсын горимд ажиллах хамгийн их чадалтай харьцуулахад маш бага байна. Мөн энэ үед түлшний максимум температур 3940 С байгаа нь түүний хайлах температур (6500 С)-аас бага байна. Иймд реакторын ажиллагаанд ямар нэгэн доголдол үүсэхгүй юм.

Олон электронт системийн электрон бүтцийн тооцооллыг квант шингэний динамик ойролцоололоор хийх нь илүү хялбар байдаг. Квант шингэний динамик болон нягтын функционалийн онолыг хослуулан хугацаанаас хамаарсан шугаманбус квант шингэний динамикын нэг тэгшитгэлийг гаргаж авсан. Энэ тэгшитгэлийг цааш нь хуурмаг хугацааны аргаар диффузын тэгшитгэлд хувиргаснаар, үндсэн төлөвийн долгионы функц рүү шилжиж шийд нь олдоно. Диффузын тэгшитгэлийг бөмбөлөг координаттай системд ерөнхий псевдоспектрийн аргаар бодсон. Энэ нь координатыг жигд биш тохиромжтойгоор дискретчилж, нарийвчлал сайтай шийдийг гаргаж авна.
