Filter by: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.
Substudy A: The study will evaluate the safety, tolerability, and efficacy of a booster dose of BNT162b2 when administered to participants having previously received 2 doses of BNT162b2 at least 6 months prior to randomization.

If participants do not consent to receive BNT162b2 as a third dose, they will not receive a third dose. No participants should receive BNT162b2 OMI as a third dose. - In healthy adults 18 to 55 years of age - The duration of the study for each participant will be up to approximately 12 months. - The study will be conducted in the United States and South Africa Substudy E: This study will assess the safety, tolerability, and immunogenicity of high-dose BNT162b2 (60 µg), high-dose BNT162b2 OMI (60 µg), and a high-dose combination of BNT162b2 and BNT162b2 OMI at 60 µg (30 µg each), given as a single dose - In healthy adults 18 years of age and older who have received 3 prior doses of BNT162b2 (30 µg) with the most recent dose being 5 to 12 months (150 to 360 days) prior to randomization - The duration of the study for each participant will be approximately 6 months. - The study will be conducted in the United States Substudy F: This study will assess the safety, tolerability, and immunogenicity of high-dose BNT162b2 (60 µg), high-dose BNT162b2 OMI (60 µg), and a high-dose combination of BNT162b2 and BNT162b2 OMI at 60 µg (30 µg each), given as a single dose. - In healthy adults 60 years of age and older who have received 3 prior doses of BNT162b2 (30 µg) with the most recent dose being ≥4 months prior to randomization - The duration of the study for each participant will be approximately 6 months. - The study will be conducted in Israel
Patients who voluntarily visit vaccination centers in Greece against COVID-19 are recruited and their immunization levels against Sars-Cov2 are assesed by measurement of the levels of serum antibodies against Sars-cov-2 before vaccination and in time intervals up to 6-9 months post-vaccination (indicatively 0-1-3-6-9 months post-vaccination).
This Phase 1 trial is an open-label trial to evaluate the safety, reactogenicity and immunogenicity of two dosages (10^6 PFU and 10^7 PFU) of intranasal CVXGA1 administered as a single dose in healthy adults age 18-55 years and in adolescents age 12-17.
An observational, retrospective, classic cohort study of adult patients hospitalized for severe pneumonia with a diagnosis of SARS-CoV-2 by RT-PCR will be carried out. The cohort will be divided into two arms: a group of patients who received treatment with anti-SARS-CoV-2 hyperimmune serum and a group of patients not exposed to the intervention during hospitalization corresponding to the period prior to the approval of the anti-hyperimmune serum SARS-CoV-2 for use. All patients will be have structured follow-up at 14, 21 and 28 days, until discharge or death.
The purpose of this study is to determine the effects of the clinical course of treatment as well as long-term symptoms of COVID-19 on respiratory function, exercise capacity, and quality of life.
During the COVID-19 pandemic, health employees are at high risk of infection. This study aimed to determine experiences with an aerosol box (AB), used with the aim of preventing contamination by droplets during internal jugular vein cannulation which requires close contact with COVID-19 patients, and the necessity to use this device.
This study is a randomized, placebo-controlled and open design, phase 4 clinical trial of an inactivated COVID-19 vaccine (CoronaVac) manufactured by Sinovac Research and Development Co., Ltd. The purpose of this study is to evaluate the immunogenicity and safety of the CoronaVac in healthy population aged 18 years and older.
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
The study is a prospective, pilot study aimed to test the safety of Tumor Treating Fields (TTFields) concomitant with best standard of care, for the treatment of hospitalized COVID-19 patients and continued treatment after hospitalization. The device is an experimental, portable, battery operated device for chronic administration of alternating electric fields (termed TTFields) to the region of the organ to be treated, by means of surface, insulated electrode arrays.
