Active clinical trials for "COVID-19"

The study is to evaluate the safety and efficacy of COVID-19 convalescent plasma (CCP) transfusion to prevent COVID-19 in adult recipients following hematopoietic stem cell transplantation. 72 patients will be randomized in a 1:1 ratio to receive either CCR (36 patients) or not (36 patients). Patients in the CCP group will receive 200 ml of CCP at +14 days, +28 days, +2 months, and +3 months following hematopoietic stem cell transplantation. Patients in the control group would be routinely given oral ursodeoxycholic acid for +14 days after transplantation. The primary goal of the study is to evaluate the safety of CCP and the incidence of COVID-19 infection within +28 days after the last infusion of CCP.

In this study, the investigators will deploy a software-based clinical decision support tool (eCARTv5) into the electronic health record (EHR) workflow of multiple hospital wards. eCART's algorithm is designed to analyze real-time EHR data, such as vitals and laboratory results, to identify which patients are at increased risk for clinical deterioration. The algorithm specifically predicts imminent death or the need for intensive care unit (ICU) transfer. Within the eCART interface, clinical teams are then directed toward standardized guidance to determine next steps in care for elevated-risk patients. The investigators hypothesize that implementing such a tool will be associated with a decrease in ventilator utilization, length of stay, and mortality for high-risk hospitalized adults.

This study is a randomized, double-blind, placebo-controlled Phase II clinical trial to evaluate the safety and immunogenicity of SCTV01E in population of different ages who have been vaccinated against COVID-19. A total of 750 participants ≥3 years old who have received the recommended dose and immunization procedure of domestically approved COVID-19 vaccines will be enrolled, including 250 participants ≥18 years old (group A), 250 participants aged 12-17 years old (group B), and 250 participants aged 3-11 years old (group C). The study will be carried out gradually according to the age of the participants from older to younger. Considering that SCTV01E in this study is the first clinical study in participants under 18 years old, 15 sentinel participants will be assigned to group B and 30 sentinel participants will be assigned to group C (including 15 aged 6-11 years old and 15 aged 3-5 years old). The Primary end points are 1. The incidence and severity of solicited adverse events on days 0-7 after inoculation with SCTV01E. 2. IgG total antibody concentrations (ELISA) against SARS-CoV-2 prototype strains and neutralizing antibodies titer (Live virus neutraliztion antibody test) against SARS-CoV-2 Omicron variant at 28 days post-vaccination.

In this study, a patient space occupied by a patient with confirmed COVID-19 in an open-space multiple bed area in the Intermediate Care Unit will be equipped with a mobile, optimally placed high efficiency particulate air ("HEPA")-equivalent air filtration unit ("Baldachin") in addition to existing hospital policy infection prevention and control measures. The investigators are going to evaluate this intervention regarding its capacity to prevent the nosocomial onwards transmission of Sars-COV2 to patients located in the same multiple-bed open space patient area.

The goal of this quasi-experimental pragmatic study is to design, implement and evaluate a psychoeducational group intervention aimed at preventing the negative consequences of the COVID-19 pandemic on the psychological wellbeing and mental health of primary care healthcare workers. The experience will be carried out in real clinical practice conditions and our purpose is to evaluate it not only in terms of clinical effectiveness but, especially, the terms of feasibility, usefulness, and possibility of this intervention being integrated into the usual practice in primary care centers. There will be two types of participation and a mixed quantitative-qualitative methodology. On one hand, the healthcare workers that will receive the intervention and participate in the study by responding to various before and after online surveys with standardized scales. On the other hand, the community psychologists in charge of implementing the intervention, having received guidelines and training, will help gather the participants' data and will provide their perceptions, assessments, and opinions on the program through other questionnaires. After the intervention, a selection of both healthcare workers and psychologists will participate in qualitative in-depth, or group interviews to explore the nuances of their perceptions of the program. The results will allow the investigators to know the usefulness and effectiveness of the intervention and, above all, to model and improve its design and implementation strategy, and promote its generalization beyond the framework of this project.

This study will investigate the efficacy of oral gabapentin in olfactory improvement following Covid-19- associated olfactory dysfunction. This is a randomized, double-blinded, placebo-controlled trial.

To evaluate the efficacy and safety of vaccinating children and adolescents, aged 3 to 17 years, with a two-dose schedule of the inactivated vaccine (Coronavac) against SARS-Cov-2.

Tuberculosis (TB) is now the commonest cause of death in many African countries. Globally, ~35% (almost 1 in 3) of TB cases are 'missed' (remain undiagnosed or undetected). In sub-Saharan Africa, 40-50% of the TB case burden remains undiagnosed within the community. These 'missed' TB cases (at primary care level) serve as a reservoir, which severely undermines TB control. With rapid advances in the development of TB screening tests, the investigators aim to determine the pragmatic utility of computer-assisted x-ray diagnosis (CAD). Recent data suggest that CAD performs on par with experienced radiologists to identify potential TB cases, hereby reducing the frequency at which Xpert tests are requested and helps to focus limited resources on the relevant cases. In addition, the investigators aim to test nascent screening technologies for TB diagnosis such as evaluating urine-based TB screening biosignatures. The COVID-19 pandemic has ravaged African peri-urban communities where TB is also common. With the pressing need to improve screening and diagnosis of COVID-19, the investigators plan to explore the potential for urine- and blood-based COVID-19 screening assays. Symptoms of COVID-19 and TB overlap, and limited affordability, as well as the stigma associated with both diseases, severely limits testing. Data are now urgently needed about the feasibility of co-screening and testing for TB and COVID-19. The utility of such an approach, if any, has not been studied in African communities.

The risk for the development of complications from COVID-19 occurs mainly in patients over 65 years of age, with obesity, arterial hypertension, chronic lung diseases and immunosuppression states. Since the persistence of radiological imaging correlates with physiological deterioration, these patients are likely to be at increased risk of parenchymal lung disease. It is known that the administration of Ozone, in any of the three phases of COVID-19 infection, is useful in the management of acute disease, both for its viricidal and anti-inflammatory activity, however, in the convalescence stage when the persistence of sequelae that can severely affect the quality of life of patients is identified.
