Interrogating higher education's responses to international student mobility in the context of the COVID-19 pandemic.

Since the COVID-19 pandemic, international higher education and student mobility have faced tremendous pressure and challenges. To address COVID-induced challenges and stress, higher education institutions and host governments undertook responses. This article has humanistically looked into the institutional responses of host universities and governments to international higher education and student mobilities during the COVID-19 pandemic. Informed by a systematic literature review of publications released between 2020 and 2021 in a wide range of academic sources, we argue that many of these responses were problematic and did not adequately maintain student well-being and fairness; instead, international students were treated to some extent with poor services in the host countries. To situate our comprehensive overview and propose ideas for forward-thinking conceptualisation, policy, and practice in higher education in the context of the ongoing pandemic, we engage with the literature on ethical and humanistic internationalisation of higher education and (international) student mobilities.

Scientometric assessment of scientific documents published in 2020 on herbal medicines used for COVID-19.

Objective: Many studies have suggested herbal medicines as alternatives or adjuvants to modern drugs for COVID-19. Their scientometric analyses can provide a scientific overview of this topic. Materials and methods: Web of Science (WOS) and Scopus were searched for articles on the use of herbal medicines in COVID-19 published until 26 October 2020. Collected data were analyzed for document type, subject area, top journal, citation number, and authors' collaboration network using VOSviewer 1.6.15, ScientoPy 2.0.3, Gephi 0.9.2, and SPSS 15 statistical tools. Results: After screening the 3185 retrieved records, 378 and 849 records, respectively from WOS and Scopus, remained for quantity analysis. Original and review articles were the two main types of papers in both databases. Top subject areas were drug and medicine, respectively in the WOS and Scopus databases. The top three productive countries in the field were China, the US, and India. The most cited article was a practice guideline in both databases. "Journal of Biomolecular Structure Dynamics" in WOS and "Chinese Traditional and Herbal Drugs" in Scopus were the top journals. Top keywords included "COVID-19″ and "Traditional Chinese Medicine". US authors had the highest collaboration with other authors. Conclusions: The current study provides a snapshot of the quantity and characteristics of published scholarly documents in recent months in the intersection of herbal medicines and COVID-19. Our findings help scientists to find the existing gaps, identify the active authors and scientific institutes to collaborate with and use their experience to produce new knowledge in the future.

Comparison of Coronary Artery Involvement and Mortality in STEMI Patients With and Without SARS-CoV-2 During the COVID-19 Pandemic: A Systematic Review and Meta-Analysis.

BACKGROUND: Cardiovascular injury with SARS-CoV-2 infection is well known. Several studies have outlined baseline characteristics in patients presenting with STEMI and SARS-CoV-2. Paucity in data exists in selective coronary involvement in patients with STEMI and SARS-CoV-2 during the COVID-19 pandemic. METHODS: A systematic search and meta-analysis of studies meeting the inclusion and exclusion criteria obtained from MEDLINE, Scopus, and Cochrane databases was performed utilizing PRISMA criteria. The main outcome was likelihood of coronary artery involvement among patients with STEMI and SARS-CoV-2 versus without SARS-CoV-2. The primary adverse outcome measured was in-hospital mortality. RESULTS: The final analysis included 5 observational studies with a total of 2,266 patients. There was no statistical significance in LM (OR 1.40; 95% CI: 0.68, 2.90), LAD (OR 1.09; 95% CI 0.83, 1.43), LCX (OR 1.17; 95% CI: 0.75, 1.85), or RCA (OR 0.59; 95% CI: 0.30, 1.17) disease among the 2 groups. LAD disease was the most prevalent coronary involvement among patients with STEMI and SARS-CoV-2 (49.6%). Higher in-hospital mortality was observed in the STEMI and SARS-CoV-2 group (OR 5.24; 95% CI: 3.63, 7.56). CONCLUSIONS: Our analysis demonstrated no statistical significance in selective coronary involvement in patients with STEMI and SARS-CoV-2 during the COVID-19 pandemic. The higher mortality among patients with SARS-CoV-2 and STEMI has been noted in prior studies with concerns being late presentation due to fear of infection, delayed care time, and poor resource allocation. Focus should be placed on identifying and managing comorbidities to reduce mortality.

Chloroquine, hydroxychloroquine, and COVID-19: Systematic review and narrative synthesis of efficacy and safety.

The COVID-19 pandemic has required clinicians to urgently identify new treatment options or the re-purposing of existing drugs. Of particular interest are chloroquine (CQ) and hydroxychloroquine (HCQ). The aims of this systematic review are to systematically identify and collate 24 studies describing the use of CQ and HCQ in human clinical trials and to provide a detailed synthesis of evidence of its efficacy and safety. Of clinical trials, 100% showed no significant difference in the probability of viral transmission or clearance in prophylaxis or therapy, respectively, compared to the control group. Among observational studies employing an endpoint specific to efficacy, 58% concurred with the finding of no significant difference in the attainment of outcomes. Three-fifths of clinical trials and half of observational studies examining an indicator unique to drug safety discovered a higher probability of adverse events in those treated patients suspected of, and diagnosed with, COVID-19. Of the total papers focusing on cardiac side-effects, 44% found a greater incidence of QTc prolongation and/or arrhythmias, 44% found no evidence of a significant difference, and 11% mixed results. The strongest available evidence points towards the inefficacy of CQ and HCQ in prophylaxis or in the treatment of hospitalised COVID-19 patients.

Neurological manifestations of COVID-19 and other coronaviruses: A systematic review.

OBJECTIVE: To describe the main neurological manifestations related to coronavirus infection in humans. METHODOLOGY: A systematic review was conducted regarding clinical studies on cases that had neurological manifestations associated with COVID-19 and other coronaviruses. The search was carried out in the electronic databases PubMed, Scopus, Embase, and LILACS with the following keywords: "coronavirus" or "Sars-CoV-2" or "COVID-19" and "neurologic manifestations" or "neurological symptoms" or "meningitis" or "encephalitis" or "encephalopathy," following the Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Seven studies were included. Neurological alterations after CoV infection may vary from 17.3% to 36.4% and, in the pediatric age range, encephalitis may be as frequent as respiratory disorders, affecting 11 % and 12 % of patients, respectively. The Investigation included 409 patients diagnosed with CoV infection who presented neurological symptoms, with median age range varying from 3 to 62 years. The main neurological alterations were headache (69; 16.8 %), dizziness (57, 13.9 %), altered consciousness (46; 11.2 %), vomiting (26; 6.3 %), epileptic crises (7; 1.7 %), neuralgia (5; 1.2 %), and ataxia (3; 0.7 %). The main presumed diagnoses were acute viral meningitis/encephalitis in 25 (6.1 %) patients, hypoxic encephalopathy in 23 (5.6 %) patients, acute cerebrovascular disease in 6 (1.4 %) patients, 1 (0.2 %) patient with possible acute disseminated encephalomyelitis, 1 (0.2 %) patient with acute necrotizing hemorrhagic encephalopathy, and 2 (1.4 %) patients with CoV related to Guillain-Barré syndrome. CONCLUSION: Coronaviruses have important neurotropic potential and they cause neurological alterations that range from mild to severe. The main neurological manifestations found were headache, dizziness and altered consciousness.
