NCT ID: NCT04957017 Completed - Chronic Disease Clinical Trials

Effect of Hand-Washing Training in Covid-19

Start date: August 15, 2020
Phase: N/A
Study type: Interventional

This study was conducted in order to inform, the women with chronic disease in rural areas, about hand-washing and nutrition, and to evaluate the efficiency of the training program. A randomized-controlled trial was performed based on CONSORT checklist. 90 women in total were included in the study, 45 for each group. The women in the intervention group were given, by the researcher, the training on the importance of hand-washing and appropriate food choices. The training given to the women in rural areas created significant benefit for them to have the appropriate food choices and hand-washing behaviours.

NCT ID: NCT04953247 Completed - COVID-19 Pneumonia Clinical Trials

Use of Compromised Lung Volume in Monitoring Usage of Steroid Therapy on Severe COVID-19

Start date: February 7, 2020
Phase:
Study type: Observational

Since December 2019, the outbreak of coronavirus disease 2019 (COVID-19) has become a public health emergency of international concern. Although corticosteroid therapy represents a milestone in the management of COVID-19, many questions remain unanswered. The optimal type of corticosteroids, timing of initiation, dose, mode of administration, duration, and dose tapering are still unclear. An approach to resolve these issues is to develop accurate tools to assess or monitor the progression of COVID-19 during the corticosteroid therapy process. Quantitative computed tomography (QCT) analysis may serve as a tool for assessing the severity of COVID-19 and for monitoring its progress. However, the effect of steroids on quantitative chest CT parameters during the treatment process remains unknown. In this retrospectively study, we aimed to assess the association between steroid administration and QCT variables in a longitudinal cohort with COVID-19
