Coronavirus Disease 2019: Past, Present, and Future.

Severe acute respiratory syndrome coronavirus 2 is one of the most impactful diseases experienced in the past century. While the official national health emergency concluded in May of 2023, coronavirus disease 2019 (COVID-19) continues to mutate. As the summer of 2023, all countries were experiencing a new surge of cases from the EG.5 Omicron variant. Additionally, a new genetically distinct Omicron descendant BA2.86 had been detected in multiple countries including the United States. This article seeks to offer lessons learned from the pandemic, summarize best evidence for current management of patients with COVID-19, and give insights into future directions with this disease.

Molnupiravir Real-World Utilization in COVID-19 Patients in the Czech Republic.

Background/Objectives: Molnupiravir (MOV), an oral antiviral COVID-19 treatment, was introduced in the Czech Republic in December 2021 for COVID-19 patients at a high risk of progression to severe disease requiring hospitalization. In this observational, retrospective study, we aimed to describe the characteristics and healthcare resource utilization in non-hospitalized, adult COVID-19 patients prescribed MOV in the Czech Republic between 1 January and 30 April 2022. Methods: A total of 621 patients were included and followed up with for 28 days. Results: The median age was 68.0 (20-99) years, 77.8% were overweight or obese, 14.1% smoked, and 85.7% were vaccinated. The overall cumulative incidence (95% CI) of all-cause hospitalization was 0.71 (0.37; 1.24) per 1000 person years or 1.9%, with similar rates across sexes, age groups, BMI category, multimorbidity category, polypharmacy category, and COVID-19 vaccination status. Among patients reported hospitalized, oxygen-based resources were not observed, and no deaths occurred. Conclusions: These data describe the characteristics and healthcare resource utilization in Czech MOV-treated patients whose clinical characteristics may put them at increased risk of severe disease.

Current challenges in different approaches to control COVID-19: a comprehensive review.

Background: The World Health Organization declared the outbreak of the novel coronavirus (COVID-19) as a global health emergency on January 30, 2020, and as a pandemic disease on March 11, 2020. This review highlights the international situation, risk factors, and related protections to be taken as prerequisite measures and probable treatment options for the COVID-19-infected population in the current scenario. Main text: The SARS-CoV-2 viruses and their variants caused mild-to-severe respiratory tract infection and used airborne pathways as a way of contagion. Human-to-human transmission led to an exponential growth in the rise in the number of cases making it a real burden to immobilize the rapid spread of the virus while asymptomatic patients created ambiguity for confirmation in the community. It was clear from the case studies of patients that most of them were asymptomatic but still vulnerable to the people around, and hence, in a flash, many countries around the globe went into a complete lockdown, influencing the economy and thrashing industrial outputs. On the other hand, numerous researches were made to counteract the spread through studies in antiviral therapy, immune-based therapy, vaccination development, and natural remedies. Conclusion: Although exploration for a specific drug required for the COVID-19 treatment is under extensive research worldwide and some of them are in clinical trial now. Virtual drug library screening is one of the current techniques for repurposing accessible compounds. This review could provide beneficial information about the potential current and future treatment strategies to treat the pandemic COVID-19 infection.

UHMS Position Statement: Hyperbaric Oxygen (HBO2) for COVID-19 Patients.

There have been numerous recent inquiries regarding use of hyperbaric oxygen (HBO2) for patients with COVID-19. Questions have been raised pertinent to two possible mechanisms for HBO2 in this clinical context. The UHMS Hyperbaric Oxygen Therapy Committee, UHMS Executive Committee, with collaborative input from multiple senior UHMS members and researchers have drafted this position statement.

Infectious Diseases Society of America Guidelines on the Treatment and Management of Patients with COVID-19

Develop evidence-based rapid guidelines intended to support patients, clinicians and other health-care professionals in their decisions about treatment and management of patients with COVID-19.

Chinese Guidelines related to Novel Coronavirus Pneumonia

China has managed to control the coronavirus disease (COVID-19) with confinement measurements and treatment strategies, while other countries are struggling to contain the spread. This study discussesthe guidelines related to COVID-19 in China in order to provide important references for other countries in the fight against COVID-19. Chinese guidelines relevant to COVID-19 were systematically searched via the China National Knowledge Infrastructure database, YiMaiTong database, and World Health Organization (WHO) COVID-19 database on March 20th , 2020. Guideline information was extracted, including date of publication, source, objectives and the target population. Guidelines specific to the pharmacological treatment of COVID-19 were further investigated to identify the types of antivirus drugs recommended and to report on how treatment recommendations for COVID-19 have evolvedovertime. A total of 114 guidelines were identified, of which 87 were national guidelines and 27 were regional guidelines. The scope of included guidelines consisted of: the diagnosis and treatment of COVID-19, the management of hospital departments and specific diseases during the outbreak of COVID-19. Sixty-four of theincluded guidelines targeted all COVID-19 patients, whilethe remainingguidelines concentrated onspecialpatientpopulations (i.e., geriatric population, pediatric population, and pregnant population) or patients with coexistingdiseases. Twenty-three guidelines focused on the pharmacological treatments for all COVID-19 patients.Interferon, Lopinavir/Ritonavir, Ribavirin, Chloroquine, and Umifenovir represented the most recommended antivirus drugs. With the emergence of encouraging results from preclinical and preliminary clinical studies, Chloroquine Phosphate was recommended in the national Diagnosis and Treatment Protocol for NovelCoronavirus Pneumonia (6th version) on February 19th, 2020. Thereafter, more detailed guidelines regarding theadjustment of dosage regimens and the monitoring of adverse events of Chloroquine Phosphatewere published. To date, 8 Chinese guidelines have recommendedChloroquine Phosphate or Hydroxychloroquine as mainstream antivirusdrug for the treatment of COVID-19. China has generated a plethora of guidelines covering almost all aspects of COVID-19. Chloroquine, as one widely affordable treatment, holds great potential to become the gold standard choice as more clinical evidence is shared by researchers from China as well as other countries.

Australian guidelines for the clinical care of people with COVID-19 - Australian National COVID-19 Clinical Evidence Taskforce

This guideline aims to provide specific, patient-focused recommendations on management and care of people with suspected or confirmed COVID-19. With the exception of chemoprophylaxis for the prevention of infection in people exposed to COVID-19, the guideline does not include other interventions used in the prevention of COVID-19 infection or transmission. Within each recommendation, the patient population of interest is specified.
