Virtual Health Promotion Work-Integrated Learning Placements: A COVID-19 Consequence or Preparation for the Future?

We explored student and industry supervisors' experiences of virtual work-integrated learning (vWIL) health promotion placements during the COVID-19 pandemic. Using a descriptive phenomenological qualitative methodology, we conducted semi-structured interviews with eight students and eight supervisors of undergraduate health promotion-related placements at community, not-for-profit and government organizations. We asked participants about the aspects of their placement they found most enjoyable and challenging, their preparation, workload, and thoughts on placement structure. We audio-recorded and had the interviews transcribed. Our thematic analyses revealed four key themes: (1) the impact of COVID-19 on work and study, (2) benefits of vWIL (real-world application and career clarification, transcending barriers and saving time, and feeling less intimidated), (3) challenges of vWIL (experiencing workplace culture, providing support and guidance to students, and relationship building), and (4) recommendations on the evolution of vWIL (increased preparation and consider a hybrid model). Our findings suggest that vWIL is a viable and sound mode of delivery for health promotion-related placements, particularly in situations that inhibit face-to-face learning. It has the capacity to enhance the work-readiness of health promotion graduates while adding flexibility to professional preparation workplace-based training programs, providing opportunity for capacity building locally across rural and remote areas, as well as globally. Future research should examine the effectiveness, practicality, and feasibility of implementing placements across different models including face-to-face, virtual and hybrid.

Deep convolutional neural networks for detection of abnormalities in chest X-rays trained on the very large dataset.

One of the main challenges in the current pandemic is the detection of coronavirus. Conventional techniques (PT-PCR) have their limitations such as long response time and limited accessibility. On the other hand, X-ray machines are widely available and they are already digitized in the health systems. Thus, their usage is faster and more available. Therefore, in this research, we evaluate how well deep CNNs do when it comes to classifying normal versus pathological chest X-rays. Compared to the previous research, we trained our network on the largest number of images, 103,468 in total, including 5 classes such as COPD signs, COVID, normal, others and Pneumonia. We achieved COVID accuracy of 97% and overall accuracy of 81%. Additionally, we achieved classification accuracy of 84% for categorization into normal (78%) and abnormal (88%).

CONSUMER ADOPTION OF INTERNET AS A MARKETING CHANNEL FOR TRADITIONAL FOOD PRODUCTS

Manufacturers of traditional food products in Serbia frequently face the issues with placement of their products. Therefore, the aim of this research is to determine if usage of Internet more intensively as a marketing channel for promotion and distribution of traditional food products may improve the sales of the products in question. Furthermore, this survey will reveal if the consumers in Serbia adopt Internet as a marketing channel for informing and procurement of traditional food products, as well as what are the benefits and what may be the barriers of using Internet. Chosen survey instrument was a questionnaire. The questions were created in the Google questionnaire, and the respondents have been chosen by the "snowball" method, in the way that the questionnaire link was sent to email addresses of a huge number of responders, with the plea that the link is shared further. Number of filled questionnaires was 1124, out of which the sample was reduced to 893 respondents, after the first eliminatory question. The research was conducted on the territory of Serbia in April and May, 2022. The results have shown that the traditional food products in Serbia are still predominantly bought of the markets, and directly from the manufacturers, while Internet is still on the last place as a distribution channel. However, what is significant is the fact that the consumers are widely using Internet to get informed about the traditional food products and the manufacturers producing them, as well as about the location where these can be bought. Furthermore, the most important information which every website should contain in order to make further procurement of traditional food products have been identified. These results present useful guideline for both manufacturers and sellers of the traditional food products, which might serve as principles in making a certain website content.

Transmission of SARS-CoV-2 in a primary school setting with and without public health measures using real-world contact data: A modelling study.

Background: Stringent public health measures have been shown to influence the transmission of SARS-CoV-2 within school environments. We investigated the potential transmission of SARS-CoV-2 in a primary school setting with and without public health measures, using fine-grained physical positioning traces captured before the COVID-19 pandemic. Methods: Approximately 172.63 million position data from 98 students and six teachers from an open-plan primary school were used to predict a potential transmission of SARS-CoV-2 in primary school settings. We first estimated the daily average number of contacts of students and teachers with an infected individual during the incubation period. We then used the Reed-Frost model to estimate the probability of transmission per contact for the SARS-CoV-2 Alpha (B.1.1.7), Delta (B.1.617.2), and Omicron variant (B.1.1.529). Finally, we built a binomial distribution model to estimate the probability of onward transmission in schools with and without public health measures, including face masks and physical distancing. Results: An infectious student would have 49.1 (95% confidence interval (CI) = 46.1-52.1) contacts with their peers and 2.00 (95% CI = 1.82-2.18) contacts with teachers per day. An infectious teacher would have 47.6 (95% CI = 45.1-50.0) contacts with students and 1.70 (95% CI = 1.48-1.92) contacts with their colleague teachers per day. While the probability of onward SARS-CoV-2 transmission was relatively low for the Alpha and Delta variants, the risk increased for the Omicron variant, especially in the absence of public health measures. Onward teacher-to-student transmission (88.9%, 95% CI = 88.6%-89.1%) and teacher-to-teacher SARS-CoV-2 transmission (98.4%, 95% CI = 98.5%-98.6%) were significantly higher for the Omicron variant without public health measures in place. Conclusions: Our findings illustrate that, despite a lower frequency of close contacts, teacher-to-teacher close contacts demonstrated a higher risk of transmission per contact of SARS-CoV-2 compared to student-to-student close contacts. This was especially significant with the Omicron variant, with onward transmission more likely occurring from teacher index cases than student index cases. Public health measures (eg, face masks and physical distance) seem essential in reducing the risk of onward transmission within school environments.

Student and Educator Perspectives of Adapting to Remote Health Professions Education: A Mixed-Methods Study.

During the COVID-19 pandemic, universities across the world transitioned rapidly to remote education. Engaging with a curriculum that has been transitioned from in-person to remote education mode is likely to impact how students and educators adapt to the changes and uncertainties caused by the pandemic. There is limited knowledge about individual differences in students' and educators' adaptability to remote education in response to the pandemic. This paper explored healthcare students' and educators' adaptability experiences to remote education. Drawing on pragmatism, a convergent mixed-methods design was adopted. Data were collected between May and August in 2020 using an online survey, followed by interviews with students and educators of five large health courses at an Australian research-intensive University. Data included 476 surveys and seven focus group interviews with 26 students, and 95 surveys and 17 individual interviews with educators. Results were interpreted through an integration of quantitative and qualitative elements from student and educator experiences. Findings indicated that students were less adaptable than educators. Whilst remote learning was less appealing than in-person learning, some students adapted well to the new learning environment. Limited social learning, transmissive pedagogy, and lack of technical and non-technical skills were identified as factors that impacted upon the experience of students and educators. Navigating the challenges associated with remote education provided students and educators with a unique opportunity to improve adaptability-an attribute critical for future uncertainties in healthcare practice.

Effectiveness of public health measures in reducing the incidence of covid-19, SARS-CoV-2 transmission, and covid-19 mortality: systematic review and meta-analysis.

OBJECTIVE: To review the evidence on the effectiveness of public health measures in reducing the incidence of covid-19, SARS-CoV-2 transmission, and covid-19 mortality. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Medline, Embase, CINAHL, Biosis, Joanna Briggs, Global Health, and World Health Organization COVID-19 database (preprints). ELIGIBILITY CRITERIA FOR STUDY SELECTION: Observational and interventional studies that assessed the effectiveness of public health measures in reducing the incidence of covid-19, SARS-CoV-2 transmission, and covid-19 mortality. MAIN OUTCOME MEASURES: The main outcome measure was incidence of covid-19. Secondary outcomes included SARS-CoV-2 transmission and covid-19 mortality. DATA SYNTHESIS: DerSimonian Laird random effects meta-analysis was performed to investigate the effect of mask wearing, handwashing, and physical distancing measures on incidence of covid-19. Pooled effect estimates with corresponding 95% confidence intervals were computed, and heterogeneity among studies was assessed using Cochran's Q test and the I2 metrics, with two tailed P values. RESULTS: 72 studies met the inclusion criteria, of which 35 evaluated individual public health measures and 37 assessed multiple public health measures as a "package of interventions." Eight of 35 studies were included in the meta-analysis, which indicated a reduction in incidence of covid-19 associated with handwashing (relative risk 0.47, 95% confidence interval 0.19 to 1.12, I2=12%), mask wearing (0.47, 0.29 to 0.75, I2=84%), and physical distancing (0.75, 0.59 to 0.95, I2=87%). Owing to heterogeneity of the studies, meta-analysis was not possible for the outcomes of quarantine and isolation, universal lockdowns, and closures of borders, schools, and workplaces. The effects of these interventions were synthesised descriptively. CONCLUSIONS: This systematic review and meta-analysis suggests that several personal protective and social measures, including handwashing, mask wearing, and physical distancing are associated with reductions in the incidence covid-19. Public health efforts to implement public health measures should consider community health and sociocultural needs, and future research is needed to better understand the effectiveness of public health measures in the context of covid-19 vaccination.

Impact of the COVID-19 pandemic on teaching and learning in health professional education: a mixed methods study protocol.

BACKGROUND: Due to the complex nature of healthcare professionals' roles and responsibilities, the education of this workforce is multifaceted and challenging. It relies on various sources of learning from teachers, peers, patients and may focus on Work Integrated Learning (WIL). The COVID-19 pandemic has impacted many of these learning opportunities especially those in large groups or involving in person interaction with peers and patients. Much of the curriculum has been adapted to an online format, the long-term consequence of which is yet to be recognized. The changed format is likely to impact learning pedagogy effecting both students and teachers. This requires a systematic approach to evaluation of online teaching and learning adaptation, in comparison to the previous format, where, in person education may have been the focus. METHODS: The proposed study is a broad based evaluation of health professional education in a major Australian University. The protocol describes a mixed methods convergent design to evaluate the impact of online education on students and teachers in health professional courses including Medicine, Nursing, Allied Health and Biomedical Science. A framework, developed at the university, using Contribution Analysis (CA), will guide the evaluation. Quantitative data relating to student performance, student evaluation of units, quantity of teaching activities and resource utilization will be collected and subjected to relevant statistical analysis. Data will be collected through surveys (500 students and 100 teachers), focus groups (10 groups of students) and interviews of students and teachers (50 students beyond graduation and 25 teachers, for long term follow up to 12 months). Application of CA will be used to answer the key research questions on the short term and long-term impact of online education on teaching and learning approaches. DISCUSSION: The protocol describes the study, which will be widely implemented over the various courses in Health Professional Education and Biomedical Science. It will evaluate how students and teachers engage with the online delivery of the curriculum, student performance, and resources used to implement these changes. It also aims to evaluate longitudinal outcome of student learning attributes and impact on graduate outcomes, which is poorly reported in educational literature.
