Introduction: Coronavirus disease-2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) swept rapidly throughout the world. So far, no therapeutics have yet proven to be effective. Ribavirin was recommended for the treatment of COVID-19 in China because of its in vitro activity. However, evidence supporting its clinical use with good efficacy is still lacking.
Methods: A total of 208 confirmed severe COVID-19 patients who were hospitalized in Wuhan Union West Campus between 1 February 2020 and 10 March 2020 were enrolled in the retrospective study. Patients were divided into two groups based on the use of ribavirin. The primary endpoint was the time to clinical improvement. The secondary endpoints included mortality, survival time, time to throat swab SARS-CoV-2 nucleic acid negative conversion, and the length of hospital stay.
Results: 68 patients were treated with ribavirin while 140 not. There were no significant between-group differences in demographic characteristics, baseline laboratory test results, treatment, and distribution of ordinal scale scores at enrollment, except for coexisting diseases especially cancer (ribavirin group vs no ribavirin group, P = 0.01). Treatment with ribavirin was not associated with a difference in the time to clinical improvement (P = 0.48, HR = 0.88, 95% CI = 0.63-1.25). There were also no significant differences between-group in SARS-CoV-2 nucleic acid negative conversion, mortality, survival time, and the length of hospital stay.
Conclusions: In hospitalized adult patients with severe COVID-19, no significant benefit was observed with ribavirin treatment.

Background: We previously reported that social restrictions due to the COVID-19 pandemic led to a decline in cognitive function in patients with Alzheimer disease (AD). Here, we assessed the effects of COVID-19 restrictions on the activities of daily living (ADL) and disease severity in patients by comparing them to a control group.
Methods: We examined the impact on ADL, evaluated using disability assessment for dementia (DAD), and disease severity, evaluated using the ABC dementia scale, in patients with mild-to-moderate AD.
Double-blind randomised trial of saline solution for gargling and nasal rinsing in SARS-CoV-2 infection.

Background: Previous studies have shown that hypertonic saline nasal irrigation and gargling reduced the duration of symptoms in upper respiratory infections caused by coronavirus. This study aims to investigate the effects of two saline regimens on symptoms associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).
Methods: Between 2020 and 2022, individuals aged 18-65 years who tested positive for SARS-CoV-2 infection via polymerase chain reaction (PCR) were randomly assigned to either low- or high-saline regimens for 14 days.

Systemic capillary leak syndrome (SCLS) is a rare and life-threatening disorder characterized by acute hypotension, hypoalbuminemia, and hemoconcentration, which often results in severe respiratory complications, such as pulmonary edema. SCLS can be triggered by infections, including COVID-19, and is associated with a high mortality rate. Here, we report a case of COVID-19-associated SCLS in a 68-year-old man.

The COVID-19 pandemic has raised concerns regarding its potential impact on premature ovarian insufficiency (POI). This overview examines the possible interactions between COVID-19 and POI, while also suggesting preventive measures. The viral infection's inflammatory response and immune dysregulation may adversely affect ovarian tissues, leading to inflammation and damage.
