Filter by:Severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) and the associated coronavirus disease 2019 (COVID-19) have been spreading all around the world for past 3 years. Some of these convalescent individuals experienced long- term sequelae termed 'long COVID', or 'post- acute COVID-19 syndrome'(PACS). Common manifestations are systemic, neuropsychiatric, cardio- respiratory and gastrointestinal [1]. The prevalence of gastrointestinal PACS was 2-5% in different literatures [2][3]. The risk factors of gastrointestinal PACS include anosmia, ageusia, and presence of chronic bowel disease, dyspeptic symptoms and the psychological comorbidity [4]. Previous articles have discussed pathogenesis of PACS, which was associated with increasing serum cytokine level and persisted inflammatory status [5]. Whereas, the influence of chronic inflammation to target organ has not been well studied. Liu et al explored the gut microbiota dynamics in patients with PACS, which revealed higher levels of Ruminococcus gnavus, Bacteroides vulgatus and lower levels of Faecalibacterium prausnitzii [6]. Another article established the association between multisystem inflammatory syndrome in children (MIS-C) and zonulin-dependent loss of gut mucosal barrier [7]. According to previous studies, infectious enteritis may cause subsequent post infectious irritable bowel syndrome [8][9], which was associated with increased gut permeability, T-lymphocyte, Mast cell and proinflammatory cytokine [10][11]. It is reasonable that gastrointestinal PACS might be also associated with dysfunction of gut mucosal barrier. Confocal laser endomicroscopy (CLE) is a new endoscopic imaging tool that enables visualization of gut mucosa changes. The gut permeability could be accessed by CLE in patient with irritable bowel syndrome [12]. This study aimed to explore the association between gut permeability and gastrointestinal PACS.
The aim of our cohort is to collect prospectively, in a standardized and exhaustive manner, the health data of patients referred to the CAPCoV, our holistic referal post covid clinics for post-covid condition in order to be able to identify typical profiles of patients suffering from post covid syndrome and to follow the evolution of their disease over time.
The present study aims to evaluate how commonly diagnostic tools employed in the preoperative evaluation of respiratory function in thoracic surgery can identify pathological alteration due to a previous SARS-CoV-2 infection. In particular, the investigators will gather information concerning imaging (lung ct and lung ultrasound), arterial blood gas analysis, and pulmonary function tests.
Pain is among the most frequently reported symptoms in Long COVID, along with sleep disturbances, fatigue, and cognitive impairments. Sleep plays a critical role in maintaining a pain-free state. The goal of this study is to characterize the type and severity of pain in Long COVID, to characterize sleep and sleep disturbances in Long COVID, and to understand the role of sleep in the development and persistence of pain symptoms in Long COVID.
Treatments are needed to improve outcomes among patients hospitalized for COVID-19, including direct-acting antiviral (DAA) agents to mitigate the pathology driven by ongoing viral replication. This trial will evaluate S-217622 (ensitrelvir), an anti-SARS-CoV2 3C-like protease inhibitor (PI) developed by Shionogi &; Co. Ltd. The study design is a randomized, placebo-controlled, multi-center international clinical trial that will evaluate the clinical efficacy of ensitrelvir when given in addition to standard of care (SOC) for inpatients with COVID-19. The SOC will be determined by local established guidelines and may include additional DAA (e.g., remdesivir) and immunomodulatory treatment strategies. Certain SOC treatments will be pre-specified prior to randomization.
The aim of the present study is to answer the question of whether a rehabilitation measure has a positive effect on fatigue symptoms, physical performance, and the physical and psychological well-being of the patients. In particular, the fatigue that occurs in most of all patients is of interest here. In order to make this measurable, the FAS questionnaire plays a special role, which should be completed by all 100 patients upon inclusion in the study and upon discharge from the rehabilitation clinic. In addition, the HADS-D questionnaire (Hospital Anxiety and Depression Scale) for self-assessment of depressive symptoms and anxiety symptoms and the SF-12 questionnaire (Short Form Health Survey) are used as a screening tool to assess health-related quality of life. For the clinical examination of physical performance, the six-minute walk test, a body plethysmography and a long-term ECG are performed on recruited patients on admission and before discharge. In a three-month follow-up, all recruited patients should receive an FAS, HADS-D and SF-12 questionnaire to fill out. Some of these will also be called back to the clinic to check the development of lung function or performance, defined on the basis of VO2max, and will undergo an additional spiroergometric examination. Thus, the effectiveness and effectiveness of the rehabilitation measures in patients under long-COVID is checked.
This clinical trial adopts a randomized, double-blind and placebo-controlled design. A total of 16000 participants are planned to be enrolled, of which, Cohort 1: 15000 participants vaccinated with ≥2 doses of inactivated COVID-19 vaccine for ≥6 months will be randomly administered at ratio of 1:1:1 with 1 dose of LIBP-Rec-Vaccine, BIBP-Rec-Vaccine or placebo intramuscularly to the deltoid muscle of upper arm. Cohort 2: 1000 participants vaccinated with ≥2 doses of mRNA COVID-19 vaccine for ≥6 months will be randomly administered at ratio of 1:1 with 1 dose of LIBP-Rec-Vaccine or BIBP-Rec-Vaccine intramuscularly to the deltoid muscle of upper arm.
This multicenter, prospective, non-interventional cohort study aims to evaluate data on humoral and cellular immune response generated within the COVID-19 vaccination standard in patients with B-cell non-Hodgkin lymphoma (NHL) or Hodgkin lymphoma (HL) who underwent autologous hematopoietic stem cell transplantation (HSCT) or who were treated with or chimeric-antigen-receptor-T-cells (CAR-T).
The purpose of this study is to collect data generated by standard clinical practice to determine the short term and long term clinical outcomes of recipients of solid organ transplantation from COVID-19 infected donors and compare it to recipients with organ transplant from COVID-19 negative donors.
The COVID-19 pandemic has transformed healthcare delivery; arguably, the fields of obstetrics and pediatrics have experienced some of the greatest changes as they have transitioned away from their role as a medical home and into more of an urgent care model of care. Baby2Home is a digital health intervention designed to bridge the resultant gaps in obstetrics and pediatrics healthcare services for new families over the first year of life. This randomized controlled trial will evaluate whether, compared to usual care, Baby2Home 1) improves maternal, paternal, and infant health service utilization outcomes over the first year postpartum, 2) improves maternal and paternal patient reported outcomes, and 3) reduces racial/ethnic and income-based disparities in preventive health services utilization and parental patient reported outcomes.
