Randomized Controlled Trial
Clinical study on the treatment of Qingfei Paidu Granules combined with nondrug therapy for asymptomatic patients with novel coronavirus.
The COVID-19 pandemic, ongoing for over 2 years with evolving viral strains, including the highly infectious Omicron variant, underscores the pivotal role of Traditional Chinese Medicine (TCM) in pandemic intervention. Qingfei Paidu Granules (QFPG) are incorporated into the national TCM diagnosis and treatment protocol. This study aims to assess the clinical effectiveness of QFPG combined with nonpharmacological interventions in asymptomatic novel coronavirus infection. ⋯ Combining QFPG with traditional Chinese nonpharmacological interventions effectively shortened the conversion time of COVID-19 nucleic acid detection and reduced the conversion rate from asymptomatic infection to mild/moderate cases. This treatment approach is worth promoting in the management of asymptomatic patients during pandemics.

Randomized Controlled Trial
Immunogenicity and safety of RAZI recombinant spike protein vaccine (RCP) as a booster dose after priming with BBIBP-CorV: a parallel two groups, randomized, double blind trial.
The immunity induced by primary vaccination is effective against COVID-19; however, booster vaccines are needed to maintain vaccine-induced immunity and improve protection against emerging variants. Heterologous boosting is believed to result in more robust immune responses. This study investigated the safety and immunogenicity of the Razi Cov Pars vaccine (RCP) as a heterologous booster dose in people primed with Beijing Bio-Institute of Biological Products Coronavirus Vaccine (BBIBP-CorV). ⋯ BBIBP-CorV and RCP vaccines as booster doses are safe and provide a strong immune response that is more robust when the RCP vaccine is used. Heterologous vaccines are preferred as booster doses.

Randomized Controlled Trial
Intensified screening for SARS-CoV-2 in 18 emergency departments in the Paris metropolitan area, France (DEPIST-COVID): A cluster-randomized, two-period, crossover trial.
Asymptomatic and paucisymptomatic infections account for a substantial portion of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmissions. The value of intensified screening strategies, especially in emergency departments (EDs), in reaching asymptomatic and paucisymptomatic patients and helping to improve detection and reduce transmission has not been documented. The objective of this study was to evaluate in EDs whether an intensified SARS-CoV-2 screening strategy combining nurse-driven screening for asymptomatic/paucisymptomatic patients with routine practice (intervention) could contribute to higher detection of SARS-CoV-2 infections compared to routine practice alone, including screening for symptomatic or hospitalized patients (control). ⋯ The results of this study showed that intensified screening for SARS-CoV-2 in EDs was unlikely to identify a higher proportion of newly diagnosed patients.

Randomized Controlled Trial
Patients' and GPs' views and expectations of home monitoring with a pulse oximeter: a mixed-methods process evaluation of a pilot randomised controlled trial.
Research on how home monitoring with a pulse oximeter is executed and experienced by patients with an acute illness such as COVID-19 and their GPs is scarce. ⋯ Structured home monitoring by pulse oximetry supports patients and their informal caregivers in managing, and GPs in monitoring, acute COVID-19 disease. It appears suitable for use in acutely ill patients in general practice.

Randomized Controlled Trial
Effect of bromhexine in hospitalized patients with COVID-19.
Bromhexine is a potent inhibitor of transmembrane serine protease 2 and appears to have an antiviral effect in controlling influenza and parainfluenza infection; however, its efficacy in COVID-19 is controversial. ⋯ Bromhexine is not an effective treatment for hospitalized patients with COVID-19. The potential prevention benefits of bromhexine in asymptomatic postexposure or with mild infection managed in the community remain to be determined.
