Filter by:Many structures and organs are adversely affected after COVID-19. The most obvious and common problem is lung involvement. In the pathology report of the patients, it has been shown that there are changes such as diffuse alveolar damage, bronchiolitis and interstitial fibrosis. The most prominent effect of COVID-19 in patients with reduced lung functions is reduced diffusion capacity. While the disease severity worsens, pulmonary fibrosis becomes more pronounced in cases. The complaints of dyspnea and fatigue of patients after discharged continue. Inspiratory and expiratory respiratory muscle weakness are observed in more than 50% of patients with COVID-19, measured in the first month after the discharged. This respiratory muscle weakness is associated with myopathy due to hypoxemia, oxygen support, prolonged bed rest and corticosteroid use, regardless of disease severity. It is seen that these patients with COVID-19 need exercise training because of lung involvement, decreased exercise capacity and persistence of some symptom complaints after the discharged.
Coronavirus-2019 (COVID-19) is a new virus that emerged in December 2019 and spread quickly all over the world. Problems such as hypoxia, dyspnea, increased fatigue, decreased exercise capacity and respiratory muscle strength occur in COVID-19 patients.In addition, abnormalities in skeletal muscles due to systemic inflammation, mechanical ventilation, sedation and prolonged bed rest in hospital and intensive care patients cause decreased exercise capacity.
This study presents a digital mental-health protocol designed to offer remote, personalized support to former or current COVID-19 patients. A total of 100 subjects will be enrolled. Participation is voluntary, and an extended informed-consent form is signed before any evaluation, assessment or voice/video call. Consent forms are collected remotely for those who have been discharged and are currently in remission and in-person for subjects hospitalized in a COVID-19-ward of either pneumology, internal medicine or infectious disease departments. Efforts will be made to assess all participants who have completed the minimum required intervention activities: for DigiCOVID, minimum required intervention activities include attending psychotherapy sessions at least 4 times. As the main goal of this project is to evaluate the feasibility, acceptability and usability of DigiCOVID, the investigators will conduct an analysis of the following primary outcome measures in all ITT participants: 1. Assessment of completion rate. Based on our previous studies, the investigators expect that ≥80% of participants will complete the battery of online self-reports: 2. Usability ratings obtained post-DigiCOVID via a 7-point Likert-scale questionnaire (mean rating of all responses). This is a brief and embedded post-study questionnaire on program satisfaction, clarity, and perceived benefits. Participants will rate each sentence on the following 7-point Likert scale: 1 = Completely Agree; 2 = Mostly Agree; 3 = Somewhat Agree; 4 = Undecided; 5 = Somewhat Disagree; 6 = Mostly Disagree; 7 = Completely Disagree. Based on our previous studies, the investigators hypothesize exit survey ratings of at least ≥4.5 ±1.5 on the 7-point Likert scale items; 3. Reported side effects (raw score). Based on our previous findings, the investigators expect 0 adverse events due to program use; 4. Overall program completion rate. Based on previous findings, the investigators hypothesize full program completion in ≥70% study participants. The secondary outcome measures will be collected at baseline and immediately after the treatment for all participants. The investigators designed DigiCOVID to improve mental wellbeing. Therefore, the investigators will measure the impact of the intervention by looking at pre-post changes in the following outcome measures: the General Health Questionnaire (GHQ-12) (Goldberg, 1988) , the Impact of Event Scale-Revised (IES-R) (Weiss & Marmar, 1997), the General Anxiety Disorder-7 (GAD-7) (Robert L Spitzer et al., 2006), the Insomnia Severity Index (ISI) (Morin et al., 2011), and the Patient Health Questionnaire (PHQ-9) (Kroenke et al., 2001). The investigators expect to observe a significant improvement across all these secondary outcome measures in COVID-19 patients. To verify these experimental hypotheses, the investigators will conduct the analysis based on the pre-intervention (baseline) and post-intervention data using parametric and non parametric statistical tests. The criterion for statistical significance is p < 0.05. Results with p < 0.1 will be described as trends.
The Omicron variant of concern (VOC) is currently rapidly spreading worldwide, with extremely high transmission rates, with an estimated R of >3. the investigators now have preliminary, yet unpublished data, showing slow waning of the immune response after the third dose of the BNT162b2 mRNA vaccine within 4 months after this dose . While these data would not have been worrisome in the Delta VOC era, this may be different with the emergence of the Omicron VOC. These data raise the question of when and will a 4th dose be needed to cope with the emergence of Omicron. However, if a have reached the maximal effect of the current vaccine has been reached against Omicron, with a third dose, will a 4th dose have any added value? Here, the investigators will study the potential immunogenicity of a 4th dose, together with assessing safety and effectiveness in preventing infections

This study is a multi-center, randomized, national, observer-blinded, active-controlled phase IIB clinical trial to determine the efficacy, immunogenicity, and safety of two-doses of inactive COVID-19 vaccine (TURKOVAC) vaccine versus the two-doses CoronaVac (Sinovac) vaccine in healthy adolescents aged 12-18 years.
Background: Scarce information exists in relation to the comparison of seroconversion and adverse events following immunization (AEFI) with different SARS-COV2 vaccines. Our aim was to correlate the magnitude of the antibody response to vaccination with previous clinical conditions and AEFI. Methods: A multicentric comparative study where SARS-CoV-2 spike 1-2 IgG antibodies IgG titers are being measured at baseline, 21-28 days after the first and second dose (when applicable), six months and a year of the following vaccines: BNT162b2 mRNA, mRNA-1273, Gam-COVID-Vac, Coronavac, ChAdOx1-S, Ad5-nCoV and Ad26.COV2. Mixed model and Poisson generalized linear models will be performed for the analyses.
The purpose of this study is to assess the safety and potential efficacy of Zofin administered intravenously in subjects experiencing prolonged symptoms (> 6 weeks and < 24 months) of COVID-19.
The goal of this real world efficacy study is to understand the benefit of universal social needs screening, community-based service referrals, and telephonic follow-up as a scalable strategy for preventing COVID-19 transmission, and for addressing the secondary health effects of the social, behavioral, and economic changes following the COVID-19 pandemic. With statewide community service providers, existing health information technology, and piloted methods, we seek to determine the effectiveness of universal social needs screening and community service referrals - the SINCERE intervention - in improving health outcomes of COVID-19 vulnerable and socioeconomically disadvantaged populations and whether intensive follow-up and collaborative goal-setting helps overcome barriers to community service use by patients seen in the emergency department and seeking COVID testing at community-based and mobile clinic locations.
The purpose of this study is to see how the acute stage COVID-19 treatments by use of herbal medicine (Shen Cao Gan Jiang Tang) affect quality of life and symptoms at 3 months after hospital discharge.
