Navigating the crisis: A review of COVID-19 research and the importance of academic publications - The case of a private university in Lebanon

Objectives

The threat of the Corona virus has had a profound global impact, prompting extensive discussions among academicians and medical researchers seeking to understand its implications across various fields. Consequently this review aims to explore the COVID-19 research approaches adopted at the Lebanese American University (LAU) between 2019 and 2022 and, to eventually shed light on the importance of the academic publications during this crisis period in the context of Lebanon.

Design Data sources Eligibility criteria

Studies related to "Coronavirus", "SARS-CoV-2," or "COVID-19″ were extracted from the SciVal database spanning the period 2019 to 2022. The identified studies, totaling 97 publications, were indexed in Scopus and Web of Science and underwent narrative analysis along with an evaluation using a predefined scale to determine their eligibility. The majority of the studies were literature reviews, followed by observational studies, modeling studies, systematic reviews, and meta-analyses.

Results

The majority of the identified studies (31 %) were focused on the medical field, primarily the impact of SARS-CoV-2 infection. Additionally, 22 % of studies discussed updates related to global finance and economic markets, while 18 % addressed the psychological burden of the pandemic. Other areas covered in the literature included the impact on performance, nutrition, tourism, politics, and telecommunication.

Conclusion

This study marks a pioneering endeavor that sparks a crucial dialogue regarding peer-reviewed scientific literature during a period of immense need for accurate information. The prevalence of literature reviews can be attributed to the demand for swift dissemination of preliminary findings and the increased call for COVID-19-related research. However, despite the abundance of publications in this specific domain, it is imperative for future research to shift its focus towards the development of novel therapies, preventive measures, psychological insights, and strategies to address the socioeconomic and financial burdens stemming from the pandemic. This study has the potential to establish a standardized framework for addressing similar crises across diverse fields and at various levels.

Limitations

The review readily acknowledges certain limitations. By solely relying on specific databases like Scopus and WoS, there is a possibility of inadvertently overlooking relevant studies. Although the study provides insights into the impact of COVID-19 across different fields and their respective publications, it is important to recognize that the continuous updates to databases and potential exclusions of related studies may have imposed constraints on the findings. Moreover, the urgency for expeditious peer-review during the pandemic may have heightened the chances of errors and diminished transparency. This urgency has unfortunately increased the risk of fraudulent activities and misconduct.

Virtual Reality and Cardiac Diseases: A Systematic Review of Applications and Effects

Introduction

Cardiac diseases have grown significantly in recent years, causing many deaths globally. Cardiac diseases can impose a significant economic burden on societies. The development of virtual reality technology has attracted the attention of many researchers in recent years. This study aimed to investigate the applications and effects of virtual reality (VR) technology on cardiac diseases.

Methods

A comprehensive search was carried out in four databases, including Scopus, Medline (through PubMed), Web of Science, and IEEE Xplore to identify related articles published until May 25, 2022. Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guideline for systematic reviews was followed. All randomized trials that investigated the effects of virtual reality on cardiac diseases were included in this systematic review.

Results

Twenty-six studies were included in this systematic review. The results illustrated that virtual reality applications in cardiac diseases can be classified in three categories of physical rehabilitation, psychological rehabilitation, and education/training. This study revealed that the use of virtual reality in psychological and physical rehabilitation can reduce stress, emotional tension, Hospital Anxiety and Depression Scale (HADS) total score, anxiety, depression, pain, systolic blood pressure, and length of hospitalization. Finally, the use of virtual reality in education/training can enhance technical performance, increase the speed of procedures, and improve the user's skills, level of knowledge, and self-confidence as well as facilitate learning. Also, the most limitations mentioned in the studies included small sample size and lack of or short duration of follow-up.

Conclusions

The results showed that the positive effects of using virtual reality in cardiac diseases are much more than its negative effects. Considering that the most limitations mentioned in the studies were the small sample size and short duration of follow-up, it is necessary to conduct studies with adequate methodological quality to report their effects in the short term and long term.

Acute Cardiovascular Complications of COVID-19: A Systematic Review

Since the pandemic in 2019, coronavirus 2019 (COVID-19) has continued to be linked with a variety of organ systems and complications. While it is generally considered a respiratory disease, its link with the heart is widely discussed in the literature. This article focuses on the acute cardiovascular complications of COVID-19 and the possible predictors of these complications. Our study included 97 articles (58 case reports, eight case series, 23 retrospective cohort studies, five prospective cohort studies, and three cross-sectional studies). Several mechanisms have been proposed to explain COVID-19-induced cardiovascular complications, with cytokine-induced inflammation and direct cardiac damage noted as the significant focus. Patients with underlying cardiovascular complications such as hypertension and diabetes were noted to be at increased risk of acute cardiovascular complications, as well as an increased risk of severe disease and death. Also, acute myocardial infarction and arrhythmias were two of the most common acute cardiovascular complications noted in our review. Other acute cardiovascular complications are myocarditis, takotsubo syndrome, acute thromboembolic events, and pericardial complications. This article provides an updated review of acute cardiovascular complications of COVID-19, its pathogenesis, and risk stratification and emphasizes the need for high suspicion in patients with underlying cardiovascular risk factors.
