The study is planned to assess the safety, clinical and virologic outcomes of early oral nirmatrevir-ritonavir treatment of COVID-19 in patients with stage 4 and 5 chronic kidney disease.

NCT ID: NCT05623007 Recruiting - Health Behavior Clinical Trials

Dietary Modulation of Gut Microbiota in Overweight/Obese Adolescents and COVID-19 Infection

DIVINE
Start date: November 1, 2022
Phase: N/A
Study type: Interventional

Probiotic intervention has been currently suggested to provide supportive benefits in promoting health, including alleviating disease symptoms, protecting against diarrhea and respiratory infection, affecting growth and modulating the immune system by improving the beneficial gut microbiota colonization, giving direction on the gut-lung-axis pathway. This indicates that probiotics may become alternative to improve nutrition and reduce the risk of viral infections which may reduce the risk against Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2). Introduction to probiotics during adolescence can alleviate inflammation and invert dysbiosis. However, evidence on the effect of probiotic supplementation on enhancing antibody response to SARS COV-2 in adolescents is lacking. Moreover, previous studies showed the potential effect of probiotic supplementation to improve overweight and obesity in adolescents. A bi-directional relationship exists among nutrition, infection, and immunity as changes in one element will affect the others. The main objective of this study is to investigate the effect of dietary modulation of overweight and obese adolescent's gut microbiota through probiotic supplementation combined with healthy eating and physical activity counseling and psychosocial stimulation on nutritional status and antibody response to COVID-19 vaccination. This trial will conduct a 20-week intervention for overweight and obese adolescents.

NCT ID: NCT05622669 Active, not recruiting - Heart Failure Clinical Trials

Understanding Patterns of Fatigue in Health and Disease

FATIGUE
Start date: December 7, 2021
Phase:
Study type: Observational

Fatigue is a common symptom and can be the most distressing symptom of a range of medical conditions. This Ecological Momentary Assessment study will investigate lived experiences of fatigue in detail in individuals with myeloma, long COVID, heart failure, and in healthy controls without fatigue. Participants will wear ECG patches and wrist-worn sensors that measure heart rate variability, activity levels, posture, and other parameters. They will self-rate their levels of fatigue four times daily and on-demand (when fatigue levels are noticeably good or troublesome). They will participate in an end of study interview and will have an optional feedback session with a researcher to make sense of the data they have provided.

NCT ID: NCT05621993 Recruiting - Clinical trials for COVID-19 Respiratory Infection

An Observational, Ambispective Cohort Study of Azvudine in the Treatment of Patients With COVID-19 Pneumonia

Start date: November 22, 2022
Phase:
Study type: Observational

This is a multicenter, ambispective observational cohort study. The patients with corona virus disease 2019 (COVID-19) will be included in the study. The patients will be divided into 4 groups according to the treatment mode (Azvudine treatment group within 48 hours after the first positive for nucleic acid, Azvudine treatment group after 48 hours after the first positive for nucleic acid, short course of Azvudine treatment without nucleic acid turning negative, and the control group) . This study aims to analyze the efficacy and safety of Azvudine in the treatment of patients with COVID-19.

NCT ID: NCT05621967 Withdrawn - COVID-19 Clinical Trials

Phonation Therapy to Improve Symptoms and Lung Physiology in Patients Referred for Pulmonary Rehabilitation

Start date: September 7, 2022
Phase: N/A
Study type: Interventional

To investigate Phonation therapy to improve symptoms and lung physiology in patients referred for pulmonary rehabilitation. The study design will be a randomized controlled trial. The primary outcome is improvement in patient symptoms (Borg dyspnea score). Secondary outcomes are improvement in time of breath hold, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), negative inspiratory force (NIF) and improvement in quality of life. The investigators will be investigating tonation breathing techniques (TBT) exercises and music-driven vocal exercises (MDVE). The study population would be patients who are referred to pulmonary rehabilitation (PR) for symptomatic chronic lung disease. The calculated sample size for the study would be 16 patients and the duration of the study would be 8 weeks. The study would be performed after the participant's pulmonary rehabilitation session.

NCT ID: NCT05621928 Active, not recruiting - COVID-19 Vaccines Clinical Trials

NCT ID: NCT05621915 Completed - COVID-19 Clinical Trials

Nadroparin Pharmacokinetics in Different Stages of COVID-19

Start date: February 1, 2021
Phase:
Study type: Observational

Objective: The risk of thrombotic complications in critical COVID-19 patients remains extremely high, and multicenter trials failed to prove the survival benefit of escalated doses of low molecular weight heparins (LMWH) in this group. The aim of this study was to develop a pharmacokinetic model of LMWH (nadroparin calcium) according to different stages of COVID-19 severity. Design: The investigators performed a prospective observational study. Patients: Blood samples were obtained from 43 COVID-19 patients that received nadroparin and were treated with conventional oxygen therapy, mechanical ventilation, and extracorporeal membrane oxygenation. Setting: The investigators recorded clinical, biochemical, and hemodynamic variables during 72 hours of treatment. The analyzed data comprised 782 serum nadroparin concentrations and 219 anti-factor Xa levels. The investigators conducted population nonlinear mixed-effects modeling (NONMEM) and performed Monte Carlo simulations of the probability of target attainment (PTA) for reaching 0.2-0.5 IU/ml anti-Xa levels in study groups. Interventions: None. Measurements and Main Results: The investigators successfully developed a one-compartment model to describe the population pharmacokinetics of nadroparin in different stages of COVID-19. Conclusions: Different nadroparin dosing is required for patients undergoing mechanical ventilation and ECMO to achieve the same targets as those for non-critically ill patients.
