The purpose of this study is to learn more about how to better track smell recovery in people who have been infected with the SARS-CoV-2 virus (which causes COVID-19). Many people who have been infected by this virus develop changes in their sense of smell (olfaction). We are interested in measuring smell function objectively via smell cards that test odor intensity, identification, and discrimination. Objective and precise olfactory testing that can be performed in the convenience of one's home will help identify people with smell loss after infection by SARS-CoV-2. We will use results from this test to better understand the relationship between SARS-CoV-2 infection and recovery of olfactory function and to learn whether the AROMHA longitudinal smell test is a reliable olfactory function tracking tool to quantify smell loss in the context of COVID infection. These results may inform the design of therapeutic clinical trials to accelerate the recovery of smell function.
NCT05084898
Elderly people who have multiple health problems are at higher risk of illness from viral respiratory infections, such as influenza (the flu) and COVID-19. This is especially true for residents in long-term care because the usual methods of infection control (handwashing, mask-wearing, and distancing) are difficult to enforce due to the memory problems of many residents and the frequently shared common spaces. It can also be difficult to prevent the spread of viral infections within long-term care because many residents are unable to tell their caregivers when they are feeling ill. Also, some elderly people do not show typical symptoms of infection (like fever), instead they may suddenly become confused or weak. This study will test if a safe form of ultraviolet light (far-UVC) can be effective as an extra method of disinfection (in addition to usual manual cleaning) against airborne and surface viruses that can cause respiratory infections.
NCT05765396
The goal of this observational study is to evaluate new non-invasive passive surveillance technologies, Level 42 AI imPulse™ Una and TOR devices for the detection of COVID-19, Flu, and/or RSV in asymptomatic and symptomatic individuals over age of 18 undergoing COVID-19, Flu, and/or RSV screening and testing at BAMC Ft Sam Houston, TX; with and without COVID-19, Flu, and/or RSV. The hypotheses are: (H1) The imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic COVID-19 carrier versus those not infected compared to gold standard RT-PCR. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their usability between the devices. (H2) Identify if the imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic Respiratory Syncytial Virus (RSV), Influenza and Long COVID carriers versus those not infected compared to gold standard Rapid RSV and Flu Antigen Tests, or RT-PCR and molecular assays. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their captured traces in the early identification of disease/illness analyzed by the devices built in algorithms. (H3) In the mid to long-term, this approach will also be explored as a diagnostic system to explore pursue the physical (structural and mechanical) properties of cells and tissues that maintain normal cell behavior (motility, growth, apoptosis), and the critical importance of the ability of cells to sense and respond to mechanical stresses, which will be operationally critical for assessment of both traumatic and unconventional exposures in austere environments. Participants will: * Be consented; * Be screened for COVID-19, Flu, and/or RSV symptoms according to BAMC's current screening procedures; * Have study data collected; * Complete a symptoms questionnaire; * imPulseTM Una and TOR e-stethoscopes examination will be conducted; * Participants will be compensated for completing all study requirements. (Active-Duty personnel must complete the study procedures while off-duty in order to receive compensation.)
NCT06402318
The primary objective of this effort will be to optimize and operationalize innovative passive surveillance systems and in parallel, the effort will identify, evaluate, and transition groundbreaking new technologies in diagnostics for operationalization. To meet the objective and execute the deliverables for this program of effort, the A\&M Breathalyzer PROTECT Kiosk will be tested, modified and validated at Brooke Army Medical Center (BAMC). The collaborative efforts between the PI, Dr. Michael Morris at BAMC and Co-Investigator Dr. Tony Yuan at USU- Center for Biotechnology (4D Bio3) will assess the passive detection technology and provide a capability survey of use-case scenarios for different operational settings. Goals: 1. Optimization and operationalize the A\&M Breathalyzer PROTECT Kiosk, portable mass spectrometer (MS) Detector for Deployment in Military Operational Medicine Environments. The Breathalyzer will be deployed to BAMC to test its detection capabilities of COVID-19 among symptomatic and asymptomatic COVID-19 carrier vs. those not infected compared to gold standard RT-PCR. 2. Evaluate the passive sensing, breath capture system, built within the A\&M Breathalyzer PROTECT Kiosk. The conversion of the active breath capture system, currently requires a straw that the subject breaths into, where then a series of sensors built in the Breathalyzer would automatically sample the exhaled breath within proximity for recent COVID-19 exposure. This task would conclude with a set of sensors and sensor inputs that would be analyzed by the Atomic AI platform built in the device. Field testing at BAMC is planned to determine the level of detection and discrimination for sensor combinations to SARS-CoV2 components and biomarkers detected. This testing would update the Atomic AI algorithm, within the device, to understand the accuracy of positive detection and the resulting sensitivities.

NCT06008457
To compare the results obtained by analysis of a self-collected anterior nasal (AN) swab as part of the Labcorp COVID-19+Flu+RSV Test Home Collection Kit to a healthcare provider (HCP)-collected AN swab in patients with symptoms of viral respiratory infection consistent with influenza A (Flu A), influenza B (Flu B), respiratory syncytial virus (RSV) and/or SARS-CoV-2 (C-19).
NCT05019456
Viruses are a major health problem for the general public and at risk populations. Normally, detection of antibody titers is the gold standard for determining the effectiveness of the immune system following natural or vaccine caused immunization. However, determining the effectiveness of other parts of the immune system are less common due to the difficulties with testing. Furthermore, there is a critical need to address other therapies in case vaccination is not successful in immuncompromised populations. Exercise has been shown to increase the strength of the immune system against many types of viruses and therefore could be simple way to improve immunity against the COVID-19 virus. The aim of this research is to determine the effects of exercise on anti-viral immunity against many types of common viruses before and after vaccination. We hypothesize that exercise will enhance the anti-viral immunity before and after vaccination. Up to 30 healthy volunteers (age 18-44 years) will be recruited to participate in this study. For completion of Aim 1, three visits are needed totaling around 7 hours of the patient's time and for Aim 2, three visits are needed totaling around 4.5 hours of the patient's time. The initial visit will be for pre-screening and if deemed healthy enough to participate, an exercise test to determine the VO2 max of the participant will be conducted. The following visits will require a trained phlebotomist to insert an in-dwelling catheter and participants will undergo a 20-minute incremental exercise trial. Approximately 50mL of blood will be collected at four different timepoints: at rest, 60% VO2 max, 80% VO2 max, and 1-hr post-exercise. All four collected blood samples will be used to expand viral specific T-cells and compare IFN-γ rele
NCT05077917
The study hypothesis is that cromolyn, when combined with standard COVID-19 treatment, will improve patient symptoms and reduce the number of days to improved quality of life. Investigators will study the effects of adding cromolyn to the standard treatment of hospitalized patients with COVID-19 pneumonia and who require supplemental oxygen. Cromolyn will be administered as a nebulized treatment four times a day for four days followed by intranasal administration for two weeks. Investigators may also screen for biomarkers that could indicate inflammatory responses and treatment-induced improvement. Participants will receive either study drug or placebo which will be administered by nebulization for 4 days followed by 14 days of intranasal administration. Participants will be followed while in the hospital and then as outpatients up to day 21 following randomization.
NCT05035628
The objective of this project is to assess the effects of a 2-month cardiopulmonary rehabilitation program on cardiorespiratory fitness in long COVID19 patients. Quality of life, functional capacity, functional respiratory capacity, inflammatory profile, coagulation markers, cognitive functions and brain O2 saturation will also be assessed before and after the exercise rehabilitation program.
NCT05097677
The protocol, in accordance with the objectives of ORCHESTRA project - Work Package 2, aims at investigating the characteristics and determinants of COVID-19 long-term sequelae. This goal will be reached through the harmonization of follow-up strategies across the participating cohorts to allow a standardized collection of data on COVID-19 long-term sequelae. The result will be a platform including a set of data and biomaterials from large scale international cohorts, that will be uniformly recorded, prospectively tracked and analysed. The ultimate goal will be that of providing evidence to contribute to the optimization and improvement of the management and prevention of COVID-19 sequelae. The follow-up will be organized in multiple levels of tests, according to the capability of each cohort, and will include questionnaires to collect demographic, epidemiological and clinical data, physical examination, radiological exams and biological sampling. The long-term follow-up will also allow the assessment of long-term immunological response to SARS-CoV-2 infection and its association to the vaccination and to different treatment strategies, including monoclonal antibodies.
NCT04893057

To determine whether a strategy of adding venovenous ECMO to mechanical ventilation, as compared to mechanical ventilation alone, increases the number of intensive care free days at day 60, in patients with moderate to severe acute hypoxic respiratory failure.
NCT06490744
The SARS-Cov-2 infection pandemic has caused a large number of acute respiratory failures and deaths across the world. Certain factors have been identified as associated with a higher risk of developing a severe form and dying. Immunosuppression has been identified as a risk factor for progressing to a severe form. Lung transplant patients were particularly vulnerable during this period, with a high frequency of respiratory compromise, sometimes progressing towards acute respiratory distress syndrome and, at a later stage, towards fibrotic forms. The impact of the infection on the immunological status of the patient and on the tolerance of the transplant have been little studied. The various treatments implemented during the pandemic have rapidly evolved (immunotherapy, vaccination, convalescent plasma transfusion, etc.) which may have modulated this risk. The evolution of respiratory function may be linked to the respiratory infection itself, or to the severity of respiratory damage during the infection. It is therefore relevant to compare patients with a moderate form of COVID-19 (non-intubated patients) to patients with severe forms, requiring invasive ventilation in intensive care. The evolution of respiratory function after infection has not yet been studied.

NCT05572853
This research was characterized as a cross-sectional observational study, following the recommendations of the STROBE instrument. Therefore, it was conducted in the Intensive Care Unit of Otávio de Freitas Hospital (HOF) in Recife/PE, with patients over 18 years old who had a clinical diagnosis of COVID-19, using two methods of oxygen therapy (Nasal Oxygen Therapy) and (non-rebreather mask). Consequently, clinical evaluations were performed regarding the disease, severity of COVID-19, perception of respiratory effort, and electromyography of respiratory muscles. 1. Leading Question: How does the recruitment pattern of diaphragmatic and extradiaphragmatic muscles in patients with acute hypoxemia caused by COVID-19 behave when assessed through EMGs, considering the SpO2/FiO2 ratio as the analysis parameter? 2. Leading Question: Is there a relationship between the respiratory work estimated by electromyographic activity of diaphragmatic and extradiaphragmatic muscles in patients with acute hypoxemia due to COVID-19 and the parameters of respiratory frequency and levels of acute hypoxemia measured by the SpO2/FiO2 ratio? The rationale for this study is that the COVID-19 pandemic has caused significant impacts on global public health due to the high volume of respiratory complications in the face of a limited supply of healthcare resources, consequently leading to high mortality. Complications are initially manifested by acute hypoxemia associated with COVID-19 infection, sometimes silent upon visual inspection or using less sensitive methods. This complicates the management of compensatory respiratory work for hypoxemia, even with oxygen therapy support. Respiratory muscle recruitment involves aspects of inspiratory effort and ventilatory mechanics. Recognizing the presence and recruitment pattern of muscles involved in a timely manner can contribute to the clinical management success rate of individuals affected by respiratory dysfunction associated with COVID-19, especially at different levels of acute hypoxemia. Surface electromyography is a non-invasive, low-risk tool compatible with the analysis of respiratory muscle recruitment patterns. However, there are no studies describing this pattern in COVID-19 patients, serving as a basis for personalized therapeutic strategies.

NCT04930978
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the Coronavirus disease (COVID-19). Tuberculosis (TB) is the foremost cause of infectious deaths globally. In 2025, an additional 1.4 million TB deaths could occur as direct consequence of the COVID-19 pandemic. It is postulated that individuals with latent or active TB are more susceptible to SARS-CoV-2 disease and that COVID-19 disease rate is high in patients with active TB, although the evidence is still scarce. TB and SARS-CoV-2 are both infectious diseases which primarily attack the alveolar region of the lungs and share common symptoms. SARS-CoV-2 disease can induce innate and adaptive immunity, but uncontrolled inflammatory innate immunity and impaired adaptive immune responses may be associated with severe tissue damage, both locally and systemically. People with coinfection (COVID-19 and TB disease) might potentially have impaired protective immune responses and treatment outcomes, specifically as far as anti-tuberculosis treatment is concerned. However, very little is known about the immunological underpinnings in this interface between TB and COVID-19 on the effect of SARS-CoV-2 disease on disease severity, response to treatment and treatment outcomes in pulmonary tuberculosis. Investigators hypothesize that altered immunity due to prior or present asymptomatic disease with SARS-CoV-2 virus can lead to altered immune responses and systems biology, increased severity and altered treatment outcomes in TB disease. The main objective of the study would be to evaluate the baseline differences in immune cells populations immune cell responses at baseline and at the time of treatment (2nd month) and end of treatment. Further, Investigators would be evaluating the changes in proteomic profiles in a subset of these individuals. In addition, immunological assays examining differences in T cell populations, measuring levels of various cytokines and by immunophenotyping as well as other immune parameters related to innate and adaptive responses will be performed to enhance the understanding of the immunological cross-talk between active TB patients with or without SARS-CoV-2. The secondary objective would be to study the clinical features, disease severity, mycobacterial burden and treatment outcomes in a cohort of SARS-CoV-2 infected (asymptomatic PCR or Antibody+) and non-infected patients with active pulmonary TB.
