Filter by:This is a multicenter, randomized, open-label, controlled trial to evaluate the effectiveness and safety of Quinine Sulfate as an add-on therapy in hospitalized adults with COVID-19. The study is a multi-center trial that will be conducted in up to approximately 2 sites nationally. New sites may be added as needed after appropriate assessment. Interim monitoring will be conducted to evaluate the arms and for safety and effectiveness. Any changes would be accompanied by an updated sample size. Subjects will be assessed while hospitalized. All subjects will undergo a series of laboratory tests (CBC, SGOT, SGPT, Ureum, Creatinine, EKG, and PCR), clinical examination (clinical assessment, vital signs, accompanying drugs, and other medical conditions) and safety assessment (serious adverse events/ SAE) Randomization will be performed 1:1 for each arm. Arm 1 = Standard of Care (SoC) alone, arm 2 = SoC + Quinine Sulfate
This is an observational retrospective and prospective multicenter study aimed at describing the role of the COVID -19 prophylaxis with Tixagevimab and Cilgavimab in CLL or indolent B-NHL patients who received first COVID-19 prophylaxis dose between March 2022 and October 2022.
This clinical trial is to test the efficacy of a Resilience Training (RASMUS) compared to an active control condition (Progressive Muscle Relaxation, PMR) on resilience, psychological distress, and other clinical variables in a group of people out of the general population with clinically relevant psychological symptoms in the context of the COVID-19 pandemic. In addition, this randomized, controlled, parallel-group study will test the efficacy of RASMUS and PMR in relation to brain structure, function, and metabolite levels. In summary, the main study examines the efficacy of two potentially helpful interventions to improve mental health, whereas the imaging sub-study investigates the potential effects of these interventions on brain volumetry and cortical thickness, on metabolite levels in stress-related brain regions, on brain responses, as well as on functional brain connectivity and communication.
The goal of this study is to test an investigational new inhaled medication called Optate.
Prospective follow-up of children with SARS-CoV-2
People who are older, those who had underlying other health conditions and people living in poorer communities are at increased risk of complications and worse outcome from COVID-19. They are more likely to be admitted to hospital with this virus. In the UK in 2020, over 130,000 people were admitted to hospital with COVID-19. Whilst admission rates fell since then, there is a need to understand better the potential impact of the many symptoms resulting from a COVID-19 infection on patients and the health services. To achieve this, the respiratory team in the University Hospital set up a COVID-19 follow-up clinic for patients who had COVID-19 infection. In this clinic, for a period of 12 weeks patients have chest X-rays, blood tests and virtual medical consultations. The clinic has been running for three years. This study will be conducted study to understand the expectations, preferences and experiences of patients who have been receiving care in the clinic. On one hand, patients who have received care in the clinic during the last yearwill be interviewed. On the other hand, patients who have been newly referred to the clinic will be interviewed before they start it and also after 12 weeks about how their expectations have been met. Patients will be identified by their clinical team and after consenting to take part in the study, they will be interviewed by qualitative researchers who will also analyse the interview data using scientific methods. The results of this study will help understanding whether changes are to be made to this clinic and also inform future similar services should they be needed.
Individuals affected by SARS-CoV-2 infection may subsequently be affected by the so-called post-COVID syndrome. The aim of the present study is to investigate the effects of a multimodal 10-week group program consisting of self-help strategies based on complementary medicine approaches of TEM (Traditional European Medicine), TCM (Traditional Chinese Medicine), and TIM (Traditional Indian Medicine) in addition to treatment as usual versus treatment as usual alone (no active study intervention/waiting list). Endpoints of the study include subjective quantitative and qualitative as well as objective (physician-reported) variables.
The goal of this type of clinical trial is to learn about symptomatic patients with post-COVID-19 parenchymal lung abnormalities. The main questions it aims to answer are: the efficacy and safety of low-dose dexamethasone or traditional Chinese medicine in symptomatic patients with post-COVID-19 parenchymal lung abnormalities. Participants will be divided into three parallel groups：controlled group with conventional western medicine treatment including oxygen therapy, antibiotics, nebulization therapy, etc. dexamethasone group: dexamethasone 1.5mg/day for one week and 0.75mg/day for another week basing on conventional western medicine. Chinese medicine group: Strengthening spleen and tonifying lung decoction for 2 weeks basing on conventional western medicine.
Aspirin-exacerbated respiratory disease (AERD) is characterized by the presence of asthma, chronic rhinosinusitis with nasal polyposis (CRwNP), and acute respiratory reactions induced by aspirin and other cyclooxygenase-1 inhibitors. One of the well-established therapeutic options is aspirin desensitization followed by daily aspirin therapy. The potential mechanisms underlying the clinical benefit of this approach include the downregulation of CysLT1 receptor, inhibition of PGD2 and interleukin IL-4 via the signal transducer and activator of transcription 6, global (blood, urine) activation of type 2 (T2) inflammation as well as local (sputum) reduction of T2 asthma inflammation. Indeed, among current aspirin-treated patients with AERD (n=37), no one had severe acute respiratory syndrome coronavirus clade 2 (SARS CoV-2) infection and most importantly, none of them developed COVID19 during pandemic. WHY? Notably, patients with AERD did not have asthma and nasal polyps exacerbation on aspirin, which is in line with other studies. Respiratory infections, such as the current COVID-19 pandemic, target epithelial cells in the respiratory tract. SARS-CoV-2 spike (S) protein binds angiotensin-converting enzyme 2 (ACE2), and in concert with host proteases, principally transmembrane serine protease 2 (TMPRSS2), promotes cellular entry. Nasal and bronchial epithelium play a key role in the early phases of an immune response to respiratory viruses. Induced sputum (IS) and nasal lavage (NL) cells are likely the first immune cells to encounter SARS CoV-2 during an infection, and their reaction to the virus will have a profound impact on the outcome of the infection. Interferons (IFNs) are antiviral cytokines and among the first mediators produced upon viral infection. IFNs are divided into three groups based on their receptor usage; type I IFNs (IFN-α and IFN-β), type II IFN (IFN-γ), and type III IFNs (IFN-λ1 and 2). Both production of IFN and cellular response to IFN are critical steps for the restriction of viral dissemination. An interferon-stimulated gene (ISG) is a gene whose expression is stimulated by interferon. Specifically, type I and type III interferons are antiviral cytokines, triggering ISGs that combat viral infections. The type II interferon class only has one cytokine (IFN-γ), which has some antiviral activity. To conclude, the assessment of gene expression for interferon α1 (IFNA1), interferon β1 (IFNB1), interferon γ (IFNG), interferon λ1 and λ2 (IFNL1 and IFNL2) as well as for ACE2 and TMPRSS2 in sputum and nasal cells may shed new light on the course of this infection in patient with AERD during long term aspirin therapy.
A qualitative study, combining psychiatric and anthropological perspectives, focused on the lived experiences of patients who had recourse to HPNCL emergencies during the period of November 2021, as well as the experiences and perceptions of those around them - such as their family, teachers or school and nursing staff. This multi-site approach will provide a multidimensional perspective on the experience of individuals and those around them, as well as a triangulation of data. The hypotheses to explain the increase in the rate of suicidal crisis will be addressed through semi-structured interviews proposed to the participants of the study.
