ABSTRACT

This integrative review aims to provide a consolidated evidence-based appraisal of the most up-to-date guidelines and recommendations of international public and professional health regulatory bodies in relation to preparedness framework for restructuring safe delivery of dental services amid and beyond the coronavirus disease-2019 (COVID-19) pandemic. Most recent updated guidelines for dental professionals from major international health regulatory bodies were reviewed. PubMed, Google Scholar, Cochrane Central Register of Controlled Trials, WHO COVID-19 and LILACS databases, along with relevant preprints were searched, and citations were checked up to January 23, 2021. The search was performed by one author. Shortlisted articles were read and brought to consensus to be included in the study by at least two co-authors. In case of any disagreement between the judgements, an independent co-author’s decision was taken as final. Of 849 records searched, 61 articles were included in the study. Following content analysis of the global guidelines and the collected prevailing evidence, the common themes and recommendations of different guidance documents were collated and summarized into seven domains. Most guidelines have a consensus regarding implementation of rigorous administrative, engineering and environmental infection control strategies. However, variations do exist with regard to the use of respirators in non-aerosol-generating procedure (non-AGP) settings, employment of airborne precautions during non-AGPs, use of supplemental air-handling systems, and preoperative use of mouthwashes. This evidence-based analysis can serve as a useful reopening resource tool and facilitate effective restructuring for delivery of optimal, equitable and safe dental practices globally, during and while emerging from the pandemic. © 2022 The Authors.

ABSTRACT

The ongoing COVID-19 pandemic has accelerated the acceptance of virtual team collaboration as a replacement for face-to-face collaboration. Unlike face-to-face collaboration, virtual collaboration is influenced by unique factors, such as technology mediation. However, there is a lack of rigorous research that assesses the impact of virtual collaboration on the engineering design process. Therefore, the current study investigates the effect of virtual team collaboration on design outcomes by means of the model of influence, learning, and norms in organizations (MILANO) framework. To tailor MILANO for virtual collaboration, this paper first presents an empirical study of human design teams, which shows how model parameter values for face-to-face collaboration (like self-efficacy, perceived influencers, perceived degree of influence, trust and familiarity) differ from appropriate parameter values for face-to-face collaboration. The simulation results for both virtual and face-to-face collaboration show how design outcomes differ with collaboration mode. Unlike teams with a few well-defined influential individuals, the mode of collaboration does not have a significant impact on teams where all individuals are equally influential. Virtual collaboration also results in lower exploration and variety than face-to-face collaboration.

ABSTRACT

INTRODUCTION AND OBJECTIVE: Prostate abscess (PA) is uncommon and the diagnosis is often delayed or missed. Traditionally, PA has resulted from acute prostatitis or ascending genitourinary (GU) infection due to gram-negative bacilli but S. aureus is an emerging cause. The objective is to study the clinical features, management and outcomes of PA in COVID 19 period. METHODS: A prospective review of all adult patients admitted with a diagnosis of PA between April 2020 and July 2021(in COVID period) were conducted. Inclusion criteria included age ≥18 years, a GU infection syndrome, and imaging consistent with PA. RESULTS: Fifteen patients with PA were identified. The median age was 54 years. Four patients (22.7%) were immunosuppressed and 11 (50%) had diabetes. Fever (66.6%), dysuria (60%), and urinary retention (20%) were the most common presenting symptoms. Pelvic CT revealed PAs in all patients with 8/15 (53.3%) were >2 cm in greatest diameter. Urine cultures were positive in 13/15 (86.6%) patients with 4/13 (30.7%) growing S. aureus (MRSA). Fourteen patients (93.3%) were managed with antibiotics alone whereas 1 (6.6%) underwent abscess drainage. The median duration of antibiotic therapy was 32 days. CONCLUSIONS: PA is relatively uncommon and may be difficult to distinguish clinically from conditions like acute prostatitis. Optimal management usually requires both antibiotics and drainage. With the advancement in the field of radiology, newer antibiotics and early diagnosis, effective conservative management of PA has become possible. Noticing the trend of frequent occurrence of S. aureus as a cause, coverage for MRSA should be a component of empiric treatment for PA.

ABSTRACT

BACKGROUND: Measuring the success of the control of COVID-19 in any country includes a review of the mortality especially to compare the deaths of those dying in hospitals and those brought in dead (BID). The objective of this study was to compare the death groups with the demographic factors that influenced the type of death. METHODS: This was a case-control study (1:1 ratio) looking at COVID-19 secondary public data from March 2020 to February 2021. Data such as the basic demographic data and comorbidities were analysed descriptively and then using a binary-logistic regression analysis to compare the independent variables against the outcome of BID. From the database, 120 cases were included as BID (4 excluded due to insufficient information) and 120 patients from the 1006 who passed away in hospital were randomly selected as comparators. The data was analysed in SPSS v21.0. RESULTS: The mean age for the BID was 59.59 (SD: 18.74), with more males (70.8%) than females (29.2%), of which 61.7% were Malaysians, 46.7% from the state of Sabah, and 64.2% having at least one co-morbidity (50% of them had hypertension). A univariate binary logistic regression analysis yielded factors such as age, nationality, and presence of any co-morbidities that are favourable to be included into the multivariate analysis. From the final analysis, the only factor that distinguished the BID from those dying in the hospital was being a foreigner (AOR: 4.32 [95%CI: 2.02-9.24], p<0.001). CONCLUSIONS: This concluded that foreigners in Malaysia were likely to die from COVID-19 outside of the hospital compared to Malaysians. Amongst the reasons that needed to be addressed were cost, accessibility issues regarding medical care, and the testing policies in Malaysia.

ABSTRACT

It is becoming increasingly clear that individuals recovered from acute coronavirus disease 2019 (COVID-19) can develop into long-term sequelae (post-acute sequala of SARS-CoV-2 infection, PACS). While antibody response kinetics against viral particles is well studied in natural infection and vaccine, the molecular mechanisms governing disease formation remain elusive. We investigated plasma and saliva samples from COVID-19 and healthy control subjects to understand early immune responses globally after exposure to the virus. Antibody analyses showed robust IgA and IgG responses, neutralizing functions to the SARS-CoV-2, and positive correlations between matched plasma and saliva fluids. Shotgun proteomics revealed persistent inflammatory patterns in convalescent samples including dysfunction of neutrophil-fibrinogen axis, and dysregulated immune and clotting functions. Our study suggests saliva as fluid to monitor serology and immune functions to detect early and chronic signs of disease development. Further delineation of the pathophysiology in saliva may lead to discovery of novel biomarkers and therapeutic targets to patients at risk to develop PASC and chronic conditions.

ABSTRACT

During the COVID-19 pandemic, the lives of healthcare professionals are at significant threat because of the enormous workload and cross-infection risk. Ultrasound (US) imaging plays a vital role in the diagnosis and follow-up of COVID-19 patients;however, it requires a close-physical contact by the sonographer. In this context, this paper presents a Telerobotic Ultrasound (TR-US) system for complete remote control of the US probe, thereby preventing direct physical contact between patients and sonographers. The system consists of a 6-DOF robot arm at the remote site and a haptic device at the doctor's site. The control architecture precisely transmits the intended position and orientation of the US probe to the remote location for transversal and sagittal plane scanning. This architecture, when integrated with an admittance controller-based force modulation and feedback transmission, enables the radiologists to obtain high-quality images for diagnosis. The advantages and effectiveness of the system are demonstrated by conducting in-vivo feasibility study at AIIMS, Delhi, for imaging abdomen organs (liver, spleen, kidneys, bladders). The system provides image quality equivalent to a manually-guided probe, can identify various pathology and reports high acceptability among volunteers and doctors from a questionnaire survey.

ABSTRACT

Digital technology-enabled personalized and adaptive learning has emerged as a critical tool for educational institutions to satisfy the evolving needs of their students, particularly in a dynamic environment like COVID-19. Such learning provides students the necessary guidance and flexibility required in a learner-centered environment, thus improving student performance. The current study leverages the TOE model to develop an institutional-level DT-PAL student learning framework. The framework suggests that digital technology-enabled personalized and adaptive learning can provide the students with the necessary personalization, flexibility, and adaptability to meet their learning needs and enhance their learning performance. The DT-PAL framework also suggests that COVID-19 and national culture complement the relationship between digital technology-enabled personalized and adaptive learning and student performance. The analysis of Saudi national culture on Hofstede cultural dimensions suggests that digital technology-enabled personalized and adaptive learning can foster student creativity, improve teaching-learning methodologies, bridge the gender divide, increase professionalism, improve evaluation methods, and streamline curriculum. The knowledge generated by this study can help Saudi Arabia to meet its digital transformation goals under National Transformation Program. Other countries can use the knowledge generated by this study to transform their education sector and improve the learning performance of their students.

ABSTRACT

BACKGROUND: Guided by the best practices adapted from national and international bodies including the World Health Organization (WHO), the Centers for Disease Control (CDC), and the UK Joint Biosecurity Centre (JBC), this paper aims to develop and provide an empirical risk stratification and assessment framework for advancing the safe resumption of global travel during the COVID-19 pandemic. METHOD: Variables included in our model are categorized into four pillars: (i) incidence of cases, (ii) reliability of case data, (iii) vaccination, and (iv) variant surveillance. These measures are combined based on weights that reflect their corresponding importance in risk assessment within the context of the pandemic to calculate the risk score for each country. As a validation step, the outcome of the risk stratification from our model is compared against four countries. RESULTS: Our model is found to have good agreement with these benchmarked risk designations for 27 out of the top 30 countries with the strongest travel ties to Malaysia (90%). Each factor within this model signifies its importance and can be adapted by governing bodies to address the changing needs of border control policies for the recommencement of international travel. CONCLUSION: In practice, the proposed model provides a turnkey solution for nations to manage transmission risk by enabling stakeholders to make informed, evidence-based decisions to minimize fluctuations of imported cases and serves as a structure to support the improvement, planning, and activation of public health control measures.

ABSTRACT

The emergence of the COVID-19 pandemic, caused by the SARS-Cov-2 virus, directly affected the displacement of people around the world. Some countries have restricted travel from certain countries where the pandemic has not been controlled. It is expected that with the emergence of different types of vaccines to contain the spread of this virus, international travel will resume both for business, tourism, and vacation. However, how to guarantee and verify that someone was vaccinated? Therefore, it is necessary to integrate most vaccination systems worldwide to offer digital proof of vaccination. One way to do this is to use FIWARE, a curated framework from an open-source platform for smart solutions, which utilizes NGSI Standards, enabling the integration of components and providing the basis for the interoperability and portability of smart solutions. However, data exchanged between systems need to be reliable and secure. One way is to overcome these challenges is using Blockchain with NGSI as an immutable decentralized transaction ledger to integrate systems. This paper proposes a new Generic Enabler (GE) named Canis Major to be integrated into the FIWARE ecosystem solutions to provide secure interoperability between systems used to integrate vaccination systems worldwide in a post-pandemic vaccination scenario. With this solution, any integrated vaccination system can reliably verify when and what type of vaccine a person has been vaccinated to contribute to the end of the pandemic. © 2021 IEEE.

ABSTRACT

Background: With increasing popularity of surgical interventions in the past few decades in the field of Orthopaedics, conservative treatment methods were challenged by surgical techniques of fracture fixation with various implants. However, due to the COVID-19 pandemic, the need for pragmatic management that balances optimum treatment of patients against clinically safe practice has brought conservative treatment methods back into focus. Methods: The functional outcome of displaced mid-shaft clavicle fracture in 20 patients (6 females, 14 males) managed conservatively with figure of eight bandage was studied prospectively over a period of 9 months from March-November 2020. The demographic and the clinical data including the Constant Murley Score, length of shortening of the fractured clavicle, non-union and cosmetic outcome of the patients were recorded over 3 follow up visits at 2 weeks, 6 weeks and 3 months. The correlation between the study variables and the functional and clinical outcome was then calculated. Results: The mean shortening of fractured clavicle was 15.65±2.94 mm and the mean Constant Murley Score was 76.90±3.27. On an average, the union was achieved at 3 months and there were no non-union cases. Out of the 20 patients, 18 patients were satisfied with the treatment and 2 were dissatisfied with the outcome. Dissatisfaction was more among the males as compared to the females. 2 out of14 males were not satisfied. There was no significant association between the satisfaction of treatment and shortening of the bone (P value >0.05). There was a linear correlation between the Constant Murley Score and bone shortening with the functional outcome being better with lesser bone shortening. Conclusion: During the treatment of displaced mid shaft clavicle fractures in adults, the conservative management with figure of eight bandage yielded a good functional outcome with fewer follow-up visits to the hospital. The conservative treatment still had a significant place in the armamentarium of fracture management during the COVID 19 pandemic.
