NCT04323527
In December 2019, the Municipal Health Committee of Wuhan, China, identified an outbreak of viral pneumonia of unknown cause. This new coronavirus was called SARS-CoV-2 and the disease caused by that virus, COVID-19. Recent numbers show that 222,643 infections have been diagnosed with 9115 deaths, worldwide. Currently, there are no approved therapeutic agents available for coronaviruses. In this scenario, the situation of a global public health emergency and evidence about the potential positive effect of chloroquine (CQ) in most coronaviruses, including SARS-CoV-1, and recent data on small trials on SARS-CoV-2, the investigators intend to investigate the efficacy and the safety of CQ diphosphate in the treatment of hospitalized patients with severe acute respiratory syndrome in the scenario of SARS-CoV2. Preliminary in vitro studies and uncontrolled trials with low number of patients of CQ repositioning in the treatment of COVID-19 have been encouraging. The main hypothesis is that CQ diphosphate will reduce mortality in 50% in those with severe acute respiratory syndrome infected by the SARS-COV2. Therefore, the main objective is to assess whether the use of chloroquine diphosphate reduces mortality by 50% in the study population. The primary outcome is mortality in day 28 of follow-up. According to local contingency plan, developed by local government for COVID-19 in the State of Amazonas, the Hospital Pronto-Socorro Delphina Aziz, located in Manaus, is the reference unit for the admission of serious cases of the new virus. The unit currently has 50 ICU beds, with the possibility of expanding to 335 beds, if needed. The hospital also has trained multiprofessional human resources and adequate infrastructure. In total, 440 participants (220 per arm) will receive either high dose chloroquine 600 mg bid regime (4x150 mg tablets, every 12 hours, D1-D10) or low dose chloroquine 450mg bid regime (3x150mg tablets + 1 placebo tablet every 12 hours on D1, 3x150mg tablets + 1 placebo followed by 4 placebo tablets 12h later from D2 to D5, and 4 placebo tablets every 12 hours, D6-D10). Placebo tablets were used to standardize treatment duration and blind research team and patients. All drugs administered orally (or via nasogastric tube in case of orotracheal intubation). Both intervention and placebo drugs will be produced by Farmanguinhos. Clinical and laboratory data during hospitalization will be used to assess efficacy and safety outcomes.
NCT04990830
This is an investigator initiated, single-center, open-label, Phase IIb clinical trial with 40 patients (for a total of 80 patients) to assess efficacy of Low molecular weight heparin using soft mist inhaler in the treatment of critically ill patients with COVID-19 (coronavirus disease of 2019) induced ARDS (acute respiratory distress syndrome). The patients will be assigned in a 1:1 ratio to receive standard treatment protocol plus inhaled Low molecular weight heparin. The primary objective is to determine the hypoxemia improvement on a 5-point clinical scale for COVID-19 induced ARDS patients.
NCT04408326
This study aims to find out whether the use of angiotensin II, which is a drug to raise blood pressure has been approved by European Medical Agency in August 2019, as an add-on medication to increase blood pressure in patients with COVID-19, acute severe lung injury, inflammation and severe shock, compared with standard medication. In addition, the investigators will collect the data of Anakinra, another drug which is frequently used in this condition to reduce inflammation. The investigators will collect clinical data and outcomes from critical care patients. The investigators will analyse for whom these drugs are most beneficial and explore whether there are any patients who don't benefit or have side effects.
NCT04782427
The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).
NCT04979923
The COVID-19, a pandemic as declare by WHO1, has a devastating impact on health and economic worldwide2. Literature suggests that acute respiratory distress syndrome (ARDS) develops over 20% of the infected individuals with Coivd-pneumonia3 along with other symptoms like fever followed by cough and dyspnea as well as chest pain in severe cases4. The current preventative strategies are non-specific10, and current interventions are predominantly supportive1. Recently, some studies have demonstrated anti-inflammatory actions for local anesthetics including lidocaine.
NCT01968083
Human respiratory syncytial virus (RSV) is a common cause of respiratory illness in infants and children. This study will evaluate the safety and immune response to an RSV vaccine in healthy RSV-naïve children.
NCT03514823
The investigators seek to understand how reflexes from the breathing muscles influence blood pressure during exercise. Furthermore, the investigators are determining if increasing breathing muscle strength (via inspiratory muscle training) influences the respiratory muscle contribution to blood pressure during exercise.
NCT04975542
This study focused on improving breathing mechanics by using various osteopathic manipulative therapy (OMT) techniques. The investigators randomly assigned participants to a control group who received sham treatment and a treatment group who received OMT. The investigators measured variable pre- and post- treatment on both groups. The investigators observed an improvement in breathing mechanics in the treatment group.
NCT04359407
The consensus therapeutic strategy implies that COVID patients with acute lung injury due to coronavirus are routinely placed in prone position in an attempt to improve oxygenation by increasing ventilation homogeneity. The purpose of the study is to quantify with the electrical impedance tomography (EIT) the changes in the ventilation and aeration in the dorsal regions of the lung when the patient is placed in prone position.
NCT01509183
Propeller Health is collaborating with Dignity Health (formerly Catholic Healthcare West (CHW)) to carry out a focused demonstration project to evaluate the effectiveness and potential cost savings of a deployment of the Propeller Health approach to asthma management. The Propeller Health goal is to bring together the best technology and asthma insight in order to provide Dignity Health with an engaging, data-driven chronic care program to improve asthma management and lower healthcare utilization costs, and to respond to prevention-focused reforms to health insurance laws. This project has been designed to implement and evaluate a data-driven program to improve asthma management and control and lower direct costs through reductions in healthcare utilization. This program has been developed by Propeller Health and has gone through preliminary testing. Each subject participating in the study will receive an Propeller Health device, which captures the time and location of use of inhaled short-acting bronchodilators over a twelve-month period. This information is processed and delivered at regular intervals to the patient and his or her provider to support improved asthma management.
NCT02162576
Propeller Health is collaborating with the City of Louisville and other local partners to carry out a focused demonstration project that will evaluate the effectiveness of the Propeller Health approach to asthma management while exploring means to use real-time data on asthma exacerbations in a public health setting. The Asthma Data Innovation Demonstration Project (ADID) will use wireless sensor technology to develop spatial and temporal data on the use of rescue inhalers by 120 study subjects with asthma in the Louisville metropolitan area. Propeller Health will process these data to support two general strategies. Asthma self management: Rescue inhaler actuation data will be compiled into individualized feedback reports to support asthma self management. Propeller Health will combine information on individual rescue inhaler actuations with evidence-based asthma management tips into real-time reports that will be provided to subjects. ADID staff will evaluate any resulting improvements in asthma control that may be based on this information. Subjects may share reports with their healthcare providers. Municipal purposes: The second strategy is to provide aggregated and de-identified, spatial and temporal asthma rescue inhaler actuation data to City personnel and authorized public health researchers in Louisville. These data will show the times and locations of the use of rescue inhalers by the 120 study subjects throughout the greater Louisville area. ADID staff will work with City personnel and researchers to investigate how this unprecedented level of detailed information on exacerbations can be used best to increase public awareness of environmental triggers while supporting public health surveillance efforts around respiratory diseases.
NCT03331445
Non tuberculous mycobacteria (NTM), Burkholdria spp, Aspergillus in the lung are almost impossible to eradicate with conventional antibiotics. In addition COVID-19 has know current treatment. These patients have few options to treat their lung infection. Nitric oxide has broad bactericidal and virucidal properties. It has been shown that nitric oxide was safe to be inhaled for similar cystic fibrosis patients and reduced drug resistant bacteria in the lungs. Further, research indicates that clinical isolates of NTM, Burkholderia spp, Aspergillus spp and Corona-like viruses can be eradicated by 160ppm NO exposure in the laboratory petri dish. This is not the first time inhaled NO treatment has been used in patients with difficult lung infections. This study will provide more data to see if NO therapy can reduce the bacterial load in the lungs, help the patients breath better; and in the case of COVID-19 act as a anti-viral agent resulting in the reduction of incidence of oxygen therapy, mechanical assistance of BIPAP, CPAP, intubation and mechanical ventilation during the study period.
NCT04963049
The purpose of the study is to explore whether using a surgical facemask impacts performance in response exercise below vs. above the ventilatory threshold (VT). The investigatores also aim to explore the impact of sexual dimorphism in the physiological response to exercise performed within these specific intensities. Finally, the onvestigators intend to examine whether the effects of wearing a facemask affect physiological recovery at cessation of exercise
NCT04004481
Tramadol is opioid analgesic widely used to treat moderate to severe pain. It is metabolized by cytochrome CYP2D6 into two major metabolites: pharmacologically active metabolite O-desmethyltramadol (M1) and inactive N-desmethyltramadol (M2), respectively. Tramadol kinetics in a population of patients undergoing major abdominal surgical procedures, and in patients with a greater or lesser degree of organic failure, is still not well researched. The investigators will measure plasma concentrations of tramadol and its metabolites after usual tramadol doses in ICU patients after major abdominal surgery. Also analgesic affect and side effect of tramadol will be recorded.
NCT04334044
In December 2019, a new virus emerged in Wuhan, China rapidly becoming a pandemic with registered cases above 800,000 around the world. The virus is now known as SARS-CoV2 calling its disease coronavirus-19 or COVID-19. The mortality of the virus has been reported around 2-10% and its causes because of the proinflammatory immune response generated on the host. The cytokines involved in the immune response to COVID-19 are IL-1, IL-2, IL4, IL-6, IL-10, IL-12, IL-13, IL-17, GCSF, MCSF, IP-10, MCP-1, MIP-1α, HGF, IFN-γ y TNF-α. Ruxolitinib is an inhibitor of JAK 1/2 which is responsable for multiple cellular signals including the proinflammatory IL-6. Ruxolitinib works as and immunomodulator decreasing the cytotoxic T lymphocytes and increasing the Treg cells. This study is intended to stop the disregulated immune response caused by COVID-19 that generates the pneumonia and subsequent severe acute respiratory syndrome.
NCT01070888
The purpose of this study is to find out if Symbicort® (budesonide/formoterol), a new combination asthma medication, is more effective than budesonide alone in controlling exercise induced asthma. The investigators hypothesize that in children and adults who suffer from asthma and exercise induced asthma there will be less decline in lung function associated with exercise when they receive the study medication.
NCT01705964
Project Aim: To determine if intramuscular epinephrine is an effective adjunct to inhaled bronchodilators (β2 agonists) for children with severe asthma exacerbation. Hypothesis: IM epinephrine is an efficacious adjunct to inhaled bronchodilators (β2 agonists) for children with severe asthma exacerbation. Intervention: Subjects will be randomly assigned (50% chance) to receive a weight based dose of IM epinephrine 1:1000 or no adjunctive medication. The dose will be 0.2 mg for subjects 20-30 kg and 0.3 mg for subjects greater than 30 kg. This will be injected intramuscularly by an ED nurse into the anterior thigh muscles of the subject using a 1 ml syringe and a 23 gauge one inch needle. In addition to the study intervention, the standardized treatment pathway based on the current asthma guidelines in use at the investigator's center will be utilized. This pathway includes nebulized albuterol, ipratropium bromide, and systemic corticosteroids. The duration and dosages of these other interventions will be administered at the discretion of the treating provider.
NCT02630511
Although asthma is a disease of the airways, research is now showing that asthmatics are more likely to develop cardiovascular disease (CVD) compared to non-asthmatics. Vascular dysfunction is seen in people at high risk of CVD and has been linked to inflammation. During an asthma attack, levels of inflammation in the whole body increase, which could potentially explain why asthmatics are at increased risk of CVD. By exercising, people can change the amount of inflammation in their bodies, improve vascular function, and thereby reduce the risk of CVD. In the proposed study the investigators will assess if asthma attacks lead to increased risk of CVD by evaluating inflammatory levels and vascular function before and after asthma attacks. The investigators will also evaluate if exercise reduces the cardiovascular risk following asthma attacks. The results from this study will help in understanding why asthmatics are at increased risk of CVD.
NCT03682874
The long-term goal of this research program is to improve understanding of the mechanistic link between Alzheimer's disease (AD) neuropathology, acute delirium, and cognitive impairment following acute respiratory failure. In this pilot study, the study team will establish a prospective cohort of older patients with acute respiratory failure and obtain data on delirium duration, AD imaging and CSF biomarkers, and cognitive outcomes following critical illness.
