ABSTRACT
BACKGROUND: Sufficient interaction between the trainers and the trainees in medical education is always one of the biggest challenges for an educational system. This study was designed to evaluate the effect of virtual interactions within the educational content of stroke on the effectiveness of teaching for general medicine students during COVID-19 crisis. MATERIALS AND METHODS: Eight medical students applying for stroke education were divided into two groups by simple random sampling (Rafsanjan Medical School, 2020). The first group participated in an online classroom via the Adobe Connect platform without virtual interaction. The second group used a video presentation containing interaction scenarios. The effectiveness evaluation of each type of educational content was done by comparison of the final exam scores and the results of an electronic satisfaction questionnaire in each group. Finally, using SPSS software version 18, the data were analyzed with independent samples t-test. RESULTS: This study showed that the mean of the examination scores of the interactive virtual content group (6.14 ± 1.46) was significantly higher than the online class group (4.50 ± 1.50) (P < 0.001), and also the results of satisfaction assessment showed that this group was more satisfied with their educational content (P = 0.005). CONCLUSION: Evaluation of the virtual stroke training effectiveness for general medical students shows that the educational approach of video with virtual interactions is an effective learning method in medical topics and can be considered as an efficacious educational model in online teaching. © Shahad A.

ABSTRACT
This paper summarises a ONE development success story of reviving a mature brownfield in South of Oman, Field β, just within ONE year through collaboration between different disciplines, comprehensive data analysis, optimising and recompletion of existing wells. Field β, comprised of multi-stacked clastic reservoirs, was put on stream in 1980s and peaked in early 1990s. Pilot water injection started in 1993 and full field water flooding continued in 1997. After more than 35 years since start of production, one can say the field was already in the tail end of its life. It had been stabilizing at low rate after 25 years and starting to decline further and at some point was one of the potential candidates to be decommissioned. A new FDP (FDP18) for part of the field was delivered in 2018 with the first well drilled at the end of that year. In 2019, despite drilling further wells on the FDP18, production was declining and was at 2018 rate towards the year end. Intensive data analysis and integrated reservoir reviews per reservoir layers were actively performed and new opportunities and data gathering were identified. FDP18 wells from 2019 onwards were then deepened to also acquire log data over deeper than the target reservoirs. Further synergy between asset and exploration teams also instigated in new discoveries including oil in shallower carbonate reservoirs, which were logged and sampled when drilling the FDP18 wells. Declining production, low oil price and COVID-19 crisis that hit 2020 challenged the team to be more resilient and with ONE development mindset between development and WRFM team, also between asset and exploration team, existing long-term closed in and very low productivity wells were utilised to tap these new opportunities. As a result, the field production has been increased by more than double, highest since 10 years ago, with a potential of triple its production rate, all achieved through optimizing and recompletion of existing wells within 1 year, at a very attractive low UTC. © Copyright 2021, Society of Petroleum Engineers
ABSTRACT
Evaluation of predictors of mortality in patients with COVID-19. In the present study, articles published from January 2019 to December 1, 2021, were reviewed in PubMed, Scopus, Web of Science, and EBSCO databases. A software program (Endnote X8) was utilized to manage electronic titles. The 95% confidence interval for Odds ratio and mean differences, fixed effect method, and Mantel-Haenszel or Inverse-variance formula were calculated. Meta-analysis in the present study was performed using Stata 16 software. A total of 281 articles were found within the beginning search. The full text of 42 articles was reviewed, and 32 articles were excluded due to lack of access to the complete content of the article and lack of relevance to the title and purpose of the article. Finally, ten studies were selected. The odds ratio of hypertension between Surviving and Deceased cases was 0.99 (OR, 0.99 95 % CI 0.82, 1.15;p=0.00). Odds ratio of other comorbidities such as cardiovascular, diabetes and respiratory comorbidities between Surviving cases and Deceased cases was (OR, 1.0 95 % CI 0.92, 1.84;p=0.00), (OR, 0.81 95 % CI 0.72, 1.27;p=0.00), (OR, 0.78 95 % CI 0.64, 1.05;p=0.00), respectively. Meta-analysis showed that comorbidities and fatigue increased mortality rate in COVID-19 patients, and the association of onset of symptoms to admission time with COVID-19 mortality was statistically significant.
