Symptoms and psychosocial effects following hospitalization for Covid-19: A sequential, mixed-methods study from northern India.

Background It is reported that patients who have recovered from Covid-19 continue to experience various symptoms and adverse outcomes. However, this aspect has not been studied well. We aimed to evaluate these variables and the perceived impact of Covid-19 among patients discharged from a Covid hospital in northern India.

Validation of a noninvasive aMMP-8 point-of-care diagnostic methodology in COVID-19 patients with periodontal disease.

Objectives: The aim of this study was to validate an active matrix metalloproteinase (MMP-8) point-of-care diagnostic tool in COVID-19 patients with periodontal disease.

Subjects, Materials, And Methods: Seventy-two COVID-19-positive and 30 COVID-19-negative subjects were enrolled in the study. Demographic data were recorded, periodontal examination carried out, and chairside tests run for evaluating the expression of active MMP-8 (aMMP-8) in the site with maximum periodontal breakdown via gingival crevicular fluid sampling as well as via a mouth rinse-based kit for general disease activity.

The clinical association between Periodontitis and COVID-19.

Objectives: The study aimed to clinically assess the association between periodontitis and COVID-19-related outcomes.

Material And Methods: Data pertaining to patient demographics, medical history, blood parameters, periodontal clinical examination and aMMP-8 point-of-care diagnostics (both site-level and patient-level) was recorded for eighty-two COVID-19-positive patients. COVID-19-related outcomes such as COVID-19 pneumonia, death/survival, types of hospital admission and need of assisted ventilation were also assessed.
