University life in an era of disruption of covid-19: a meta-methods and multi-mixed methods research study of perceptions and attitudes of south african students

On 18 March 2020, all South African universities and colleges were closed due to the COVID-19 virus. By early April, 10 universities announced that they were planning to resume teaching and learning online, including the University of the Witwatersrand (i.e., Wits University), Johannesburg, which is the joint highest ranked university in Africa. Therefore, the purpose of this editorial was to examine the perceptions and attitudes of these students regarding online learning in an era of disruption of COVID-19, uniquely using both multi-mixed methods research approaches (i.e., involving the partial integration of multiple methods research approaches and mixed methods research approaches) and meta-methods study approaches (i.e., involving the full[er] integration of multiple methods research approaches and mixed methods research approaches). A total of 4,419 Wits University students completed an online survey. A principal components analysis of one of survey’s scales, namely, the Attitude of Students Towards COVID-19 and its Impact on Higher Education scale, revealed 2 subscales, namely, Students’ Self-regulation Towards COVID-19-Based Higher Education and Attitudes Toward Teaching, Learning, and Assessment in COVID-19-Based Higher Education. Nonparametric analyses revealed that scores on these measures discriminated gender, age group, level of student (i.e., undergraduate vs. postgraduate), locality status (i.e., local vs. international student), and registration status (i.e., full-time vs. part-time). A multiple analysis of the open-ended responses by the VOSviewer 1.6.14 text mining software program led to the identification of 6 metathemes. Similarly, WordStat 8.0.29 topic modeling yielded 5 metathemes that mapped onto VOSviewer’s 6 metathemes, indicating triangulation of findings. A sentiment analysis revealed negative sentiments that identified not only the biggest challenges for students but also the characteristics of students who experience these challenges. Finally, a cluster analysis, combined with chi-square analyses, led to the identification of 4 clusters of students who differed with respect to their attitudes and online experiences. Implications of these findings are discussed.

Bio-fungicide potential of araucaria columnaris (cook pine) aqueous resin extract against major phytopathogens.

Use of chemical fungicide to control plant diseases causes several adverse effects such as, development of resistance in the pathogen, residual toxicity, pollution to the environment etc. So an alternative way to overcome the usage of dreadful chemicals is very important. The use of plant extracts as biofungicide is one of the popular and effective method. Araucaria columnaris is a commonly seen ornamental plant known as Christmas tree. It’s a South African species, under the family Araucariaceae. Hence, in the present study, the plant resin extract was tested in-vitro against major plant pathogensby preliminary bioassay. It was found that up to 95% reduction of mycelium growth was observed against major phytopathogens such as Fusarium oxysporyum, Rhizoctoniasp, Cylindrocladiumsp, Alternariasp, and Colletrotricum sp., causing tomato wilt, damping off, foliage blight, and leaf blight diseases in economically important plants. Up to our knowledge it is the first report showing the antifungal activity of Araucaria columnaris resin as antifungal agent. By using this valuable tree, further work will be done to formulate commercial biofungicide.

Prevalence of metabolic dysfunction-associated fatty liver disease and its association with glycemic control in persons with type 2 diabetes in africa: a systematic review and meta-analysis

Metabolic dysfunction-associated fatty liver disease (MAFLD) and type 2 diabetes (T2D) are interconnected metabolic disorders with significant health implications. However, a comprehensive understanding of the extent of their co-occurrence in Africa is lacking. The aim of this review was to determine the prevalence of MAFLD and its association with glycemic control (HbA1c) in persons with T2D in Africa. A systematic search was conducted on PubMed, Medline, Embase, Scopus, Global Health, and Web of Science from their inception to December 6, 2023. Data on MAFLD prevalence and correlation coefficients regarding its association with glycemic control were pooled through random effect meta-analyses. Potential sources of heterogeneity were investigated using subgroup analysis and meta-regression. A total of 10 studies were included in the meta-analysis of MAFLD prevalence, while 2 were incorporated in the analysis of the association between MAFLD and glycemic control. The pooled prevalence of MAFLD in persons with T2D was 48.1% (95% CI: 36.1–60.3). The subgroup analysis revealed regional variations in MAFLD prevalence, with rates of 44.7% (95% CI: 28.7–62.0) in sub-Saharan Africa and 55.3% (95% CI: 36.2–73.0) in Northern Africa. Additionally, we observed an increasing trend in MAFLD prevalence, recording 55.1% (95% CI: 43.6–66.1) in the recent five years. There was a weak positive correlation between MAFLD and HbA1c (r = 0.33, 95% CI: 0.18–0.47). The findings of this study highlight a high prevalence of MAFLD in persons with T2D in Africa, with a suggested link between MAFLD and suboptimal glycemic control. Therefore, healthcare providers should prioritize the screening and management of MAFLD in individuals with T2D to enhance their metabolic health.

Hypotensive activity of melilotus officinalis (l.) pallas (hucon-2013)

Melilotus officinalis (L.) Pallas. is used traditionally to treat hypertension and chronic venous insufficiency. The high prevalence of hypertension and the side effects of antihypertensive drugs potentiate us to evaluate Melilotus officinalis. The hypotensive effect of Melilotus officinalis butanol fraction (MOBF) was investigated in anaesthetised normotensive rats. The doses of 60, 80 and 100 mg/kg, i.v., produced a significant (P <0.05) decrease in blood pressure. The statistically non substantial reduction in blood pressure was shown by 20 and 40 mg/kg, i.v. These results suggest that Melilotus officinalis exhibited a hypotensive effect in normotensive rats. However, further evaluation of compound-related activity is required.

Pygmalion effect and the process of coming –out: an exploratory case study on the identity development of student homosexuals

This exploratory case study employed Appreciative Inquiry Framework in answering the following questions: 1) What are the expectations set by the following to the student homosexuals; a) Self, b) Parents and c) Teachers; 2. What are the positive and negative effects of these expectations to the student homosexuals? and 3) How do these expectations affect the process of identity development of the student homosexuals?. The participants are five college students who identified themselves as homosexual. Written consent was secured to ensure that the research abides to the ethical standards. The data was triangulated through analysing the point of view of the student participants, their parents and their teachers. Results revealed that expectations set by the student homosexuals, their parent and teachers are all contributory factors that affect the identity development of student homosexuals. Moreover, it was revealed that those who have problems in their identity development experienced difficulties in their performance in school. Positive and negative effects of expectations were also noted as the participants shared their stories. With the results, it was recommended that teachers must treat all their students equally regardless of their gender preferences in life. Activities that support the holistic personalities of students must be given emphasis. The parents must support their children in whatever endeavour they take and provide them guidance to be successful in their academic pursuits. Lastly, a model of counselling procedure for student homosexuals was proposed.

Financial literacy education: implication on the economic and social life of the teacher in ghana

Financial literacy education is a lifelong asset that every individual needs to function and fit well in modern-day society. It provides the financially savvy better decision making, best investment alternatives and family wellbeing. Unfortunately, most consumers especially in this part of our world appear relatively less active and less confident in participating meaningfully in the financial sector due to a lack of knowledge about the complex nature of financial products and services and indeed the risk that goes with them. As a contribution in addressing this problem, this study looked at financial literacy education and its implication on the economic and social life of the teacher in the Upper East Region of Ghana. With a descriptive survey design, 118 participants responded to questionnaires. Results showed low levels of financial literacy among participants which can negatively affect their daily financial management. It is therefore definite that the financially literate has the advantage to undertake prudent alternative investment decisions and is able to make informed retirement planning. Being financially illiterate adversely affects one’s life in relation to the culture of savings, expenditure pattern, investment decisions and budgeting skills, making the individual economically insecure. The study has policy frontier implications; policymakers in the financial sector, governments, non-governmental organisations and equity owners are encouraged to come to the aid of consumers, especially teachers, by way of introducing professional teacher development programmes specifically tailored at uplifting their financial literacy knowledge and skills.

Therapeutic potential of naringin in neurological disorders

Neurological illnesses are multifactorial incurable debilitating disorders that may cause neurodegeneration. These diseases influence approximately 30 million people around the world. Despite several therapies, effective management of such disorders remains a global challenge. Thus, natural products might offer an alternative medicine for treating neurological disorders. Polyphenols, such as curcumin, resveratrol, myricetin, mangiferin, and naringin (NRG), have been shown to possess promising potential in treating neurogenerative illness. In this review, we have targeted the therapeutic potential of naringin as a neuroprotective agent. The overall neuroprotective effects and possible underlying mechanisms related to NRG are discussed. In light of the strong evidence for the neuropharmacological efficacy of NRG in various experimental paradigms, it is concluded that this molecule should be further considered and studied as a potential candidate for neurotherapeutics, focusing on mechanistic and clinical trials to ascertain its efficacy.

Navigating pharmacoeconomics in libya: our current landscape

Pharmacoeconomics (PE) is a relatively newly developed and fast-changing discipline [1]. PE plays a crucial role in healthcare decision-making by evaluating the costs and outcomes of different treatment options. In Libya, however, the implementation of PE evaluations faces various challenges that hinder its effective integration into healthcare systems. This communication analyses the current needs and prospects of PE by examining the challenges in its implementation, the benefits of integrating it into healthcare decision-making, and strategies to enhance its utilization in the country's healthcare landscape. By exploring these different aspects, it is possible to gain a comprehensive understanding of Libya's status and potential advancements in PE. In Libya, the earliest records related to PE trace back to the late 19th century, specifically around 1835 during the Turkish colonization. During that time, various documents documented details such as drug prices, direct costs associated with specific diseases, expenditures on essential pharmaceuticals, and annual inventories of health and pharmaceutical institutions [2]. Over the past 80 years since modern Libya’s establishment after the colonial era, Libyan authorities have consistently published annual statistical reports. These reports cover expenditures on medicines, pharmaceuticals, and therapeutic materials, as well as the stock levels in healthcare facilities [3]. However, despite this data, there remains a significant lack of literature on PE, with a few exceptions that do not meet the standards expected of PE studies.

Emerging technological tools and services to building world class paper less library information &management system [lims]

Library automation is just not a book inventory where hold, issue and receiving of books by using technological tools and services. Our applied research was found that most of the library administrative functionalities such as ‘Acquisition and Accessioning’, ‘auto Indexing & Classification’ and auto Cataloging (Books & Non books materials)’, inventory with real-time OPAC facilities and many more library science concepts are still missing constructs in Universities/College libraries across the country. In this modern era the concept of eLibrary is more popular because availability and accessibility of digitized content sharing through IT/ICT infrastructure is huge. During our research we found that cognizance of Library automation was completely ignored and focused on only talking and establishment of eLibrary. As we all know that “Physical Library” is not a substitute for “eLibrary”. In fact eLibrary is part of a Physical Library to share authenticated digitized content through IT/ICT infrastructure. After a decade of our applied research in the area of Library science, eventually we recorded a lot of findings based on our survey and discussion with senior researchers and Librarians. Our serious and consistent effort makes to succeeds in designing comprehensively effective and efficient operational strategies to build a “world class Library Automation and Paper less Library Management System” for Universities/College libraries. This paper emphasizes about the comprehensive real-time architecture and operational modules and their effectiveness to achieve the user’s satisfaction (flow of functionalities as per the exact need of the Library Management system). This dealt with how emerging technological tools and services are effectively integrated for designing new strategies in the area of library science includes various automation process and security concepts (using Barcode/RFID). Eventually, our dream comes true in building Use of Emerging Technological Tools and Services to building world class Paper less Library Information &Management System [LIMS]. presently deployed and use of this software product in more than 300 satisfied and client locations in INDIA, this product popularly named as “eLib” by AarGees Business Solution, Hubli, India. Though, our research is still on and continuing for further development to build “Global knowledge sharing Centre”.

Surviving trisomy 18: a case report of a 5-year-old girl

Rationale: Trisomy 18, often known as Edwards syndrome. It is a common chromosomal disorder characterized by the presence of an extra chromosome 18. Unfortunately, survival past the first year is quite rare, and there are only a few reports of individuals living long-term without needing corrective surgery. This case sheds light on an unusual situation where a patient survived for an extended period despite having severe congenital heart defects. Patient concerns: A 5-year-old girl, already diagnosed with trisomy 18, was admitted to the hospital after experiencing a cough and diarrhea that started after she began taking a nutritional powder supplement. The patient had a history of admission to neonatal intensive care for 1 month due to transient tachypnea of the newborn, mild retractions, and grunting. Additionally, she had intrauterine growth restrictions, dysmorphic features, and hypotonia. Diagnoses: Clinical examination revealed dysmorphic features, hypoxia, and a cardiac murmur. Chest radiography reveals central infiltration with cardiothoracic ratio 60%. Genetic testing confirmed the presence of trisomy 18, and an echocardiogram showed multiple congenital defects with significant right ventricular hypertrophy. Interventions: Initial management began with administering oxygen, performing metabolic tests, and a chest x-ray. However, because of ongoing low oxygen levels linked to her heart defects and pulmonary hypertension, long-term home oxygen therapy was initiated. A comprehensive supportive care with multidisciplinary team support was the main management. Outcomes: Throughout her treatment, oxygen saturation did not exceed 85%, and the patient’s development has remained severely delayed, with no significant motor or cognitive milestones. The patient had a long life expectancy for her complex heart defects, but eventually died of cardiac arrest. Lessons: This case shows the possibility of prolonged survival in trisomy 18, even with severe congenital heart defects, emphasizing the importance of multidisciplinary management and family-centered counseling. Documenting such cases expands understanding of this syndrome and guides long-term care strategies.

Variation in fruit morphological traits of jatropha curcas at stand and tree level

Nine fruit morphological traits were studied in ten stands of Jatropha curcas spread in eight forest divisions of Uttarakhand. Variation was examined at stand level as well as at tree level. Significant differences were found among stands for fruit length, fruit diameter, pericarp weight per fruit, seed: fruit weight ratio, kernel: fruit weight ratio and pericarp: fruit weight ratio traits while all morphological traits showed significant differences among trees within stands. The estimation of the variance components, however, revealed that the fruit traits, especially weight traits viz. fruit weight, total seed weight per fruit and total kernel weight per fruit have negligible contribution from stands and small contribution from trees. Maximum variation was found among fruits within trees (i.e. at fruit level or error). Pericarp weight per fruit and fruit ratio traits (i.e. seed: fruit weight ratio, kernel: fruit weight ratio and pericarp: fruit weight ratio) were affected to small extent by stand per se. The repeatability of all fruit traits at tree level were also low to moderate (0.105 to 0.278)

Near infra red spectroscopic analysis of macrotyloma uniflorum (lam.) verdc., phaseolus lunatus linn. and phaseolus vulgaris linn.

The present study is designed to determine the types of secondary metabolites in three selected seed powders using a fast, reliable, and non-destructive Near Infra Red spectroscopic analytical technique. NIRS analysis of Macrotyloma uniflorum (Lam.) Verdc., Phaseolus lunatus Linn., and Phaseolus vulgaris Linn., seed flours were used to qualitatively evaluate secondary metabolites. The fine powder of crude drug was directly applied to FOSS XDS near the infrared Rapid Content Analyzer. The adequately filled powdered sample in a disposable glass silicate vial closed with a plastic lid was centrally placed onto the Foss Rapid Content Analyzer sample presentation glass. The scanning of samples at ambient temperature gives NIR spectra within 30 seconds. The major proposed compounds in M. uniflorum were 3,4-dihydroxybenzoic acid, caffeic acid, chlorogenic acid, ferulic acid, gallic acid, kaempferol, linolenic acid, niacin, quercetin, sinapinic acid, syringic acid, and vanillic acid. Whereas coumaric acid, fructose, galactose, L-serine, raffinose, stachyose, sucrose, threonine, and tyrosine were detected in P. lunatus, and the NIR suggested the presence of caffeic acid, ferulic acid, sinapinic acid, phytic acid, leucine, and valine in P. vulgaris. NIRS is an advanced innovative technology extensively used in chemical, food, petrochemical, and pharmaceutical industries for rapid and reliable standardization. The present study revealed an excellent correlation to conclude that flour samples of all three legume seeds could be added to the food system to achieve nutritional and functional benefits.

Assessing knowledge, attitudes, and practices of augmented reality technology in dentistry: a cross-sectional survey

Introduction: Augmented Reality (AR) technology is increasingly recognized for its potential to enhance various aspects of dental practice, including treatment planning, patient education, and training. Despite this potential, the understanding of dental professionals' knowledge, attitudes, and practices regarding AR technology remains underexplored. The objective of this research is to examine the experience, perceived advantages, and real application of augmented reality (AR) Technologies of dental faculty and students. Methodology: A sample of 132 dental students, some integrated into the workforce as part-time private dentists, and faculty members of a single dental school, completed a self-administered online survey. Knowledge and application of AR technology in dentistry, and Experience with AR practice, were the constructs of the study. An administered questionnaire, partially digital and partially paper and pencil, was divided into two parts: Knowledge Assessment and Practice Assessment. The survey results were analyzed using reference statistics. Results: Knowledge Assessment respondents confirmed understanding Augmented Reality (AR) technology (69.7), and AR technology in dental training/education was recognized (65.9). 57.6% of the participants in the Practice Assessment declared absence of AR in their educational and/or professional practice, but an AR technology practice was wanted (67.4). The self-rated proficiencies that 44.47% of the respondents professed were in the range of self-score 3 in the application of AR (moderate). A small fraction (16.7) declared their AR application self-score was above the higher order. Conclusion: It can be concluded from this work that AR technology in academic and practical dentistry is vastly underutilized, notwithstanding the high realization and appreciation for its application.

An assessment of the quality of some portable water obtained within enugu metropolis

Provision of clean water is one of the United Nations Sustainable Development Goals. Water quality assessment as an ongoing exercise, in view of the threat of contamination from natural sources and human activities, plays a pivotal role in the sustainable management of water resources. Potable water samples were collected from Enugu Metropolis for water quality assessment. The physicochemical parameters were determined using APHA (1995 - 1998) protocols, and the presence of 7 heavy metals (Chromium, Zinc, Manganese, Silver, Cadmium, Iron and Lead) in the waters were determined using Atomic Absorption Spectrophotometer (AAS). The results of the physicochemical analysis of the four samples show a pH range of 8.60 - 8.95mg/l; this result showed that pH of the water samples were slightly alkaline and above the WHO stipulated range of 6.50 - 8.50. Acidity ranged from 5.00 - 6.88mg/l, while alkalinity values were between 7.52 - 13.00mg/l. The total dissolved solid (TDS) and total solids (TS) was present in very minute quantities and below their permissible limit of 0.45mg/l; while total suspended solid (TSS) was not present at all. The heavy metal analysis showed that all but 2 heavy metals (Cadmium and Lead) were below the permissible standard set by the WHO in all four samples. Cadmium was present in samples A and C with values 0.021mg/l and 0.006mg/l respectively, which is above its WHO limit of 0.005mg/l; while Lead was present in samples A, B and C with values of 0.021mg/l, 0.011mg/l and 0.015 mg/l respectively, which were above the WHO limit of 0.010mg/l. Given the well-documented toxicity of certain metals, there is a need for safety checks to be carried out in potable water companies to address the source of this contamination and ensure production of safer drinking water.
