Diagnostic Accuracy of Rapid Antigen Tests in Asymptomatic Close Contacts of Individuals With Confirmed SARS-CoV-2 Infections in the Herat Province of Afghanistan in 2021: Cross-sectional Study (Preprint)
Authors: Amirnajad Ahmad
Published: February 2022

BACKGROUND

Early detection and isolation are key strategies for containing the COVID-19 pandemic in resource-poor countries, including Afghanistan, where access to the vaccines is limited. These strategies could reduce burden on the health care system, which is already weak because of conflicts and war. The first COVID-19 case in Afghanistan was detected in the Herat province close to Iran. Currently, both rapid antigen tests and reverse transcription–polymerase chain reaction (RT-PCR) have been used for the diagnosis of COVID-19 in the Herat province.

OBJECTIVE

This study aimed to assess the accuracy of the rapid antigen test in asymptomatic close contacts of individuals with confirmed COVID-19 in the Herat province.

METHODS

This was a cross-sectional study conducted by contact-tracing surveillance teams in the Herat province. The teams listed 200 asymptomatic close contacts of individuals with confirmed COVID-19, and 2 separate nasopharyngeal specimens were collected. The rapid antigen test (Biosensor) was used on the fourth and seventh day after contact, and the second specimen was sent to the reference lab for RT-PCR testing. Descriptive statistics were calculated. The sensitivity and specificity of the rapid antigen tests were compared with those of RT-PCR.

RESULTS

The median age of the contacts was 35 years (range 11-90 years), and 138 (70%) were women. Of the 196 (98%) contacts for whom RT-PCR was used, 105 (53%) had confirmed results for SARS-CoV-2 infection. Only 30 (15%) cases of SARS-CoV-2 infection were confirmed by the rapid antigen test, which indicates a sensitivity of 20.1%. However, the specificity of the rapid antigen test was high (90%).

CONCLUSIONS

The sensitivity of the rapid antigen tests was relatively low to confirm COVID-19 in asymptomatic close contacts of individuals with confirmed COVID-19. Therefore, if resources allow, RT-PCR would be the best choice with its high sensitivity rate to diagnose COVID-19 in asymptomatic close contacts of individuals with confirmed COVID-19. Further study with a large sample size is needed.

Authors: Nie li , Oldenburg Brian , Cao Yingting
Published: February 2022

BACKGROUND

Background: Mobile health (mHealth) services are of positive significance for alleviating the unbalanced allocation of medical resources and reducing the time cost of users. But the sustainability of using mHealth services among users is still a problem.

OBJECTIVE

Objective: Through the construction of models, questionnaire surveys, and empirical verification, the study aims to explore the factors that affect continuous usage intentions of mHealth services and the mechanism of action among these factors. Moreover, it may improve users’ self-management capabilities, and provides evidences for improving the quality of digital medical services.

METHODS

Methods: Considering the uniqueness of health services and social environmental factors, this study constructed an Expectation Confirmation Model of Information System Continuance (ECM-ISC) to investigate factors that may influence the intention of continuance usage of mHealth services based on the three dimensions，which were individual, technology and environment. The questionnaires were collected by random sampling, the reliability and validity of the model were tested, the structural equation model was applied and full path analysis was performed.

RESULTS

Results: Totally there were 334 participants completing the questionnaires through cross-sectional data. Reliability and validity of the test model were good, which Cronbach’s Alpha values of 9 variables all exceeded 0.9, Composite reliability 0.8, the average variance extracted value 0.5 and the factor loading 0.8. The modified model had a good fitting effect and strong explanatory power. It accounted for 79% of the variance in expectation confirmation, 67% of the variance in perceived usefulness, 97% of the variance in customer satisfaction, and 83% of the variance in continuance usage intention. Compared with the initial hypotheses, perceived system quality didn’t affect the continuous usage intention and was deleted. The added two paths were that subjective norm was positively associated with perceived service quality（β=0.675, P<0.001）and perceived information quality（β=0.579, P<0.001）. Electronic health (E-health) literacy was positively associated with perceived usefulness (β=0.415, P<0.001), perceived service quality (β=0.207, P<0.001), and perceived information quality (β=0.343, P<0.001). Continuance usage intention was influenced by perceived usefulness（β=0.216, P<0.001）, customer satisfaction（β=0.432, P<0.001） and subjective norm（β=0.36, P<0.001）.

CONCLUSIONS

Conclusions: The study constructed a theoretical model including E-health literacy, subjective norm and technology qualities to clarify continuous usage intention of mHealth services and empirically validated the model. E-health literacy, subjective norm, perceived service quality, and perceived service quality should be paid attention to improving continuance usage intention of users and self–management by mHealth Apps managers and government.

Published: February 2022

Learner Centred Approach has been emphasized in Tanzania for several years since 1995. The country made reforms on various education policies and programs to ensure students are trained through LCA to realize national educational objectives. This study, therefore, sought to assess the implementation of LCA in public secondary schools. The study was guided by four specific objectives. Also, it was anchored on constructivism learning theory developed in 1929 and adopted in the field of education. The researcher employed a mixed research approach and a convergent parallel research design to collect data from the field. The researcher involved teachers, school heads, students, WEOs, and DEO. A sample size of 165 informants was employed to get data in quantitative and qualitative terms. Quantitative data were analyzed through SPSS version 20, while qualitative data were analyzed through the content analysis method by coding, categories, and themes. Validity and reliability of the quantitative instruments were checked to obtain 0.80 coefficients which indicated that the instruments were valid and reliable while for qualitative instruments validity and reliability were tested through triangulation. The findings demonstrated that LCA plays a significant role in developing students’ lifelong learning skills. It develops creativity, critical thinking, problem-solving skills, and innovation. Notwithstanding, the study found that teachers and students had a positive perception of the application of LCA, however its implementation in public secondary schools is minimal due to environmental challenges which lead to poor academic performance in students.

The main goal in character education is to achieve noble character to create a harmonious human life, helping each other, being fair, and having a balanced relationship in social life. Because of that, instilling character in students is fundamental so that when they grow up, they can become the next generation of solid character. This study uses library research that compares the concept of learning the character of al-Ghazali and Thomas Lickona. The research method carried out in this study was carried out with several steps, such as collecting qualitative data based on reputable data sources and analyzing data to obtain final results. The study results show that Al-Ghazali's educational method is a traditional nuanced method of "lecture and uswah hasanah". Furthermore, Al-Ghazali's educational materials are all forms of teachings contained in the Islamic religion. More clearly and concretely, the concept of education initiated by Al-Ghazali contains two elements: transcendence (rububiyyah: divine) and humanization. Meanwhile, the concept of character learning initiated by Thomas Lickona formulates character learning that involves all components in the education process, both family, school, and community. In addition, the character learning process, according to Thomas Lickona is an effort that involves three aspects of intelligence, including cognitive through moral knowing, affective through moral feeling, and psychomotor through moral acting as follows: The purpose of character learning is to help students become intelligent and good in manners.
Cell division zones are maintained by the photoassimilate--auxin--brassinosteroid--polar auxin transport signal relay in Arabidopsis root tips
Authors: Sakaguchi Jun , Watanabe Yuichiro
Published: February 2022

Light-derived signals from the shoot tissue promote root growth.
Brassinosteroids (BRs), which are phytohormones, are crucial for root
growth and leaf expansion. We previously revealed that
photoreceptor-dependent signals promote the expression of DWARF4
( DWF4), which encodes a key BR biosynthesis-related enzyme, in
the root tips. Furthermore, auxin is indispensable for root growth. In
this study, we focused on the relationships among light-derived signals,
auxin, and BR in the root tips. Polar auxin transport (PAT) in the root
tips was undetectable in plants grown on medium lacking sucrose for 24 h
in darkness; however, a BR treatment restored PAT in darkness. We also
observed that PAT was non-existent in the cell division zones under
BR-deficient conditions, even under light. On the basis of these
results, we propose that the light-dependent cooperative effects of
auxin and BR in the root tip cell division zone are necessary for
sustaining root growth.

The purpose of this research work is to develop a model to predict the effect of twist on mechanical, evenness and imperfection properties of 100% cotton ring spun yarns. Eight yarns were manufactured from 30Tex with four yarn twist increments (700, 740, 780 and 820TPM), and 15Tex with twist levels of 900, 1020, 1080 and 1140TPM (turns/meter). Except yarn count and twist level, the yarns were made from the same fiber properties and machine settings. Yarn mechanical properties such as tensile strength, elongation and abrasion resistance, evenness (CVm) and imperfection characteristics like hairiness, neps, thin and thick places were measured and statistically analyzed. Equations were developed to predict the desired mechanical, evenness, and imperfection properties of yarns based on yarn count and twist levels. Statistical analysis showed that yarn properties are significantly influenced by count and twist level changes. The tensile strength, elongation, abrasion resistance, CVm, hairiness and thick places of the studied yarns were significant at P-values of 0.000, 0.003, 0.000, 0.004, 0.000 and 0.015 respectively. Generally, as yarn twist increases, breaking strength and abrasion resistance increase, whereas elongation, hairiness, coefficient of mass variation (CVm), thin and thick places, and nep of yarn decrease. Therefore, the formulated multiple regression equations would be useful in predicting yarn properties based on its count and twist.

Feline coronavirus (FCoV) is ubiquitous in the domestic cat (Felis catus) population. The aim of this study was to determine the prevalence and potential predisposing factors of FCoV in cats of an animal shelter in Latvia and to compare the prevalence between cats in the quarantine area and resident cats in the adoption area. Oropharyngeal and faecal swabs and blood samples were collected from 40 domestic shorthair cats from an animal shelter in Jelgava, Latvia. Swabs were analyzed for FCoV RNA by reverse transcriptase-polymerase chain reaction (RT-PCR). Blood serum samples were tested for FCoV specific antibodies by indirect enzyme-linked immunosorbent assay (ELISA). FCoV RT-PCR positivity in oropharyngeal and rectal swabs was 7.5% (3/40) and 72.5% (29/40), respectively. Additionally, FCoV seroprevalence was 67.5% (27/40). The proportion of cats shedding FCoV within the adoption (72.7%) and quarantine (72.2%) areas was similar (p = 0.55). The prevalence of FCoV faecal shedding in young cats was significantly higher (p < 0.05) than in adult cats. Sex had no significant effect on FCoV RT-PCR positivity. Further studies on larger cat population including different population types are needed to determine the overall prevalence and epidemiological patterns of FCoV infection in Latvia.

The trends in the change of the profitability of Bulgarian beekeeping starting from the country’s accession to the European Union (EU) in 2007 to the present 2020, are being studied, depending on the changes in the market price of honey and its prime cost. The survey was conducted among selected apiaries in North-eastern Bulgaria. It has been found that they achieve a small net profit when selling conventional honey in the organizational markets – EUR 3.78 kg-1. The realization of organic honey as a raw material in the organizational markets is not profitable for them. The apiaries have a net profit of EUR 7.98 kg-1 for conventional and EUR 7.91 kg-1 for organic honey, with distribution to a consumer market sale. The apiaries in Ruse district achieve 10.26% profitability of turnover in sales on conventional consumer markets, 8.83% in organic consumer markets and 8.2% in organizational conventional markets. Improving their profitability requires: 1) marketing strategies, through regional and cross-sectoral integration; 2) the production of royal jelly, pollen and propolis with high added value; 3) introduction of new technologies, increase in labour productivity, and 4) state subsidies to a hive for ecosystem pollination service.

The aim of this study was to investigate the interactive effect between aging and type 2 diabetes mellitus (T2DM) on brain glucose metabolism, individual metabolic connectivity, and network properties. Using a 2 × 2 factorial design, 83 patients with T2DM (40 elderly and 43 middle-aged) and 69 sex-matched healthy control subjects (HCs) (34 elderly and 35 middle-aged) underwent 18F-fluorodeoxyglucose positron emission tomography/magnetic resonance scanning. Jensen-Shannon divergence was applied to construct individual metabolic connectivity and networks. The topological properties of the networks were quantified using graph theoretical analysis. The general linear model was used to mainly estimate the interaction effect between aging and T2DM on glucose metabolism, metabolic connectivity, and network. There was an interaction effect between aging and T2DM on glucose metabolism, metabolic connectivity, and regional metabolic network properties (all P < 0.05). The post hoc analyses showed that compared with elderly HCs and middle-aged patients with T2DM, elderly patients with T2DM had decreased glucose metabolism, increased metabolic connectivity, and regional metabolic network properties in cognition-related brain regions (all P < 0.05). Age and fasting plasma glucose had negative correlations with glucose metabolism and positive correlations with metabolic connectivity. Elderly patients with T2DM had glucose hypometabolism, strengthened functional integration, and increased efficiency of information communication mainly located in cognition-related brain regions. Metabolic connectivity pattern changes might be compensatory changes for glucose hypometabolism.

Mitochondria-associated endoplasmic reticulum membrane (MAM) may have a role in tubular injury in diabetic nephropathy (DN), but the precise mechanism remains unclear. Here, we demonstrate that the expression of phosphofurin acidic cluster sorting protein 2 (PACS-2), a critical regulator of MAM formation, is significantly decreased in renal tubules of patients with DN, and PACS-2 expression is positively correlated with renal function and negatively correlated with degrees of tubulointerstitial lesions. Conditional deletion of Pacs-2 in proximal tubules (PTs) aggravates albuminuria and tubular injury in a streptozotocin-induced mouse model of diabetes. Mitochondrial fragmentation, MAM disruption, and defective mitophagy accompanied by altered expression of mitochondrial dynamics and mitophagic proteins, including Drp1 and Becn1, are observed in tubules of diabetic mice; these changes are more pronounced in PT-specific Pacs-2 knockout mice. In vitro, overexpression of PACS-2 in HK-2 cells alleviates excessive mitochondrial fission induced by high glucose concentrations through blocking mitochondrial recruitment of DRP1 and subsequently restores MAM integrity and enhances mitophagy. Mechanistically, PACS-2 binds to BECN1 and mediates the relocalization of BECN1 to MAM, where it promotes the formation of mitophagosome. Together, these data highlight an important but previously unrecognized role of PACS-2 in ameliorating tubular injury in DN by facilitating MAM formation and mitophagy.

Pedagogy of uncertainty
Authors: Videla-Reyes Ronnie , Aguayo Claudio
Published: February 2022

Educators around the world are facing the challenges and opportunities of 21st Century education, such as the COVID-19 pandemic, STEAM education, and the rise of digital immersive technologies presenting  a promising field for the development of new ways to maximize the learning experience (Bakker, Cai & Zenger, 2021) The integration of science, technology, engineering, art and mathematics (STEAM) offers an approach to educational design based on curricular integration and learning by doing with analog and virtual technologies (Quigley et al., 2020). In turn, STEAM promotes important pedagogical changes that encourage the development of new skills focused on collaborative work, inquiry and creativity in the face of a challenge or problem to be solved, as well as optimal sensorimotor deployment through haptic and visual perception when using emerging digital immersion technologies such as virtual and augmented reality (Videla-Reyes, Aguayo & Veloz, 2021). All these changes lead to a new framework of pedagogical action based on uncertainty, since they are unfamiliar or unknown in the field of traditional education.

 

Based on the above, we propose here the idea of a ​​’pedagogy of uncertainty’, which can be read in light of the latest and unpredictable changes that 21st Century education is experiencing due to the COVID-19 pandemic, the emergence of technological tools and unfamiliar virtual and online platforms that teachers and students had to learn and use during the march of the virus. The approach that we suggest here is based on the potential of STEAM educational environment design that focuses on providing signs or patterns of an emerging world, unlike traditional teaching methods in which the path to which students should arrive is already laid down in advance. From a STEAM educational design approach, the teacher and her/his students lay down a path in walking together, a motto used by the enactive approach to cognition that considers "cognition as embodied action that is always oriented towards something absent: on the one hand, there is always a next step for the system in its perceptually guided action; for the rest, the acts of the system are always directed towards situations that are not yet in act” (Varela, Thompson & Rosch, 1991, p.238). In this presentation, we explore the notion of pedagogy of uncertainty in the light of enactivism, based on theoretical and empirical evidence about how teachers and students deal with an uncertain world by actively participating in integrated educational environments  based on learning by doing approaches (Abrahamson, Dutton & Bakker, 2021). In particular, we make special reference to how teachers can make their students learn from clues, impoverished traces, or traces of information available within their learning environments to solve a challenge or problem, to the extent that they investigate, create, manufacture and/or actively participate in technology inside and beyond the classroom.
Covid-19: Factors Affecting on Awareness Level of the Force Majeure Clause in the Construction Contract

Published: February 2022

The spread of the Covid-19 had forced the whole world to enforce the lockdown where all the business sectors and daily activities were on hold and new norms adopted since 2020 until now. The construction industry was one of the sectors severely affected by this outbreak, including Malaysia. Various construction-related issues arose, and the construction clause on Force Majeure became the talk of the town. Endless discussions and arguments arose regarding determining the Covid-19 impact to the contracting party who plan to seek relief using this clause. Thus, this study aims to evaluate the current awareness and importance of the Force Majeure clause in the construction contract in the realm of the Covid-19 outbreak. This pandemic was a new phenomenon, and there were limited law references that can be referred to in determining the best way to deal with its contractual effects. This study was carried out using a mixed methodology. Semi-structured interviews were conducted with 12 respondents, mainly the contract administration. Questionnaire surveys were distributed to 47 respondents. Interviewed data were analyzed using Atlas-ti 9 software to produce more scientific and well-grounded results, and descriptive analyses were conducted for the questionnaire survey. Finding from this paper reveals that there was a varying level of awareness of the Force Majeure clause, mainly due to a lack of experience in dealing with Force Majeure. There was a significantly different understanding of the actual Force Majeure definition and how the clause can be evoked. The respondents were also unsure how the clause could provide complete protection to the contracting parties. This study also concluded some recommendations to improve the enforcement of the Force Majeure clause for future declaration.Keywords: Force Majeure, Covid-19, Construction Industry, Contractual issues, Awareness level
