Active clinical trials for "COVID-19"

The World Health Organization (WHO) declared the 2019 novel coronavirus (COVID-19) a pandemic on March 11, 2020. As of 19 July 2020, there have been 14.3 million confirmed cases and over 600,000 confirmed deaths. Up to 14% of infected patients develop interstitial pneumonia, which may evolve to acute respiratory distress syndrome. COVID-19 associated pulmonary arterial microthrombosis and coagulopathy has prompted physicians to implicate pulmonary embolism (PE) as a potential cause for acute respiratory deterioration. Literature review reveals few studies of varying size, quality and design. Recent meta-analysis reports venous thromboembolism in approximately 20% of COVID-19 patients. There has yet to be a case-controlled study which proves and quantifies the associated between COVID-19 and PE.Confirming and quantifying this association has numerous clinical implications for the treatment of critically unwell patients with COVID-19 infection. For example, clinicians will be more inclined to investigate and treat sudden deteriorations with the knowledge that pulmonary embolism is the commonest cause for said deteriorations.

Social distancing during the COVID-19 pandemic could lead to clinical and functional deterioration of people living with chronic respiratory diseases (CRD). As they are considered risk group for COVID-19, it is not recommended that they leave their house and have interaction with people outside. Thus, most of them have not been attend Pulmonary Rehabilitation sections since the beginning of pandemic, neither exercising outdoor, experiencing drastic restrictions in their activities of daily living. It is well known that low level of physical activity in daily life (PADL) in this population is related to poor prognosis, including higher chance of hospitalization due to exacerbation and mortality. Therefore, the aim of this study is to evaluate the short- and mid-term impact of the COVID-19 pandemic on the clinical, physical and functional conditions and the PADL level of people living with CRD (chronic obstructive pulmonary disease, asthma and interstitial lung diseases). Participants will be assessed during the social isolation period and they will be reassessed immediately after release from social isolation. Thus, the subjects will be followed-up during 12 months to record symptoms, functional status, quality of life, exacerbations and hospitalizations. The researchers' hypothesis is that those patients will present very low level of PADL in association to sedentarism, poor functional status, more symptoms of dyspnoea, anxiety and depression, poor sleep quality and, consequently, will present more episodes of acute exacerbation of the disease and more hospital admission during the study protocol.

Odor and taste disturbances have increased dramatically during this time of the COVID-19 pandemic. Currently, we have very little information on the demographic and clinical characteristics of the affected population, on the severity and course of the olfactory / taste loss. The main objective of this research is to analyze the epidemiological, demographic and clinical characteristics of patients suspected or already confirmed of infection with SARS-Cov2 presenting with anosmia and / or ageusia.

Study Objectives: To perform COVID-19 diagnostic and serologic testing on emergency medical personnel in Polk County to determine: COVID-19 prevalence Rate of convalesced personnel (+antibodies) Rate of asymptomatic carriers

There were 83,85,440 confirmed cases of COVID-19 worldwide with a mortality rate of 5.4% according to the situation report of the World Health Organisation on June 19, 2020. In India there were 3,95,048 confirmed cases of COVID-19 with a mortality rate of 3.3%. In Tamil Nadu there were 54,449 confirmed cases of COVID-19 with a mortality rate of 1.2% according to the report of Ministry of Health and Family Welfare, Government of India on June 19, 2020. COVID-19 infection is a double challenge for people with diabetes. India has a large number of persons with diabetes (more than 77 million). Recent studies have reported rising prevalence both in the urban and rural populations. The incidence of type 2 diabetes (T2D) also shows an increasing trend in the last few decades. Mortality seems to be threefold higher in people with diabetes when COVD-19 coexists when compared with mortality due to COVID-19 without comorbidities. Yang et al noted that among 52 intensive care patients who had COVID 19 infection, 22% had diabetes among the non-survivors. In a study of 173 patients with severe disease, 16.2% had diabetes, and in another study of 140 hospitalized patients, 12% had diabetes. Li et al compared intensive care and non-intensive care patients who had COVID-19. They showed a twofold increase in the incidence of diabetes in intensive care patients. In addition to diabetes; the other common co-morbidities present in COVID 19 patients were hypertension (20%), cardiovascular disease (16%), and lung disease (6%). In this context, patients with diabetes have been listed as people with higher severity for COVID-19 by several health authorities. However, precise data regarding patients with and without diabetes having COVID-19 infection are still lacking. Moreover, the relationship between diabetes and the severity of COVID-19 remains unknown. In this study, we intend to identify the disease severity and mortality in people with and without diabetes admitted for COVID-19 in southern India.

The anticipated second wave of COVID-19 cases will present healthcare system challenges, including requirement to monitor large numbers of patients for deteriorating respiratory failure. Rising respiratory rate can identify deterioration requiring escalation of care. However constant monitoring of respiratory rate can be challenging outwith critical care units due to feasibility and inaccuracy of intermittent measurements. Wearable biosensors which allows for remote patient monitoring of RR is therefore attractive, particularly when combined in a dashboard with clinical summary data. This would establish source data and infrastructure for the training and validation of machine-learning models, with decision support risk-predictions prioritising alerts and clinician reviews.

The SARS-CoV-2 epidemic is leading to a large number of patients in intensive care units due to severe hypoxemic pneumonia. After an acute phase that may require controlled mechanical ventilation and deep sedation, removal of sedation often reveals a pathological awakening in the vast majority of patients. This encephalopathy state remains, to date and to our knowledge, unexplained. Clinical features do not appear to fully correlate with regular delirium. This encephalopathy might be explained by deep and prolonged hypoxemia, a wide use of sedation drugs, systemic inflammation or the hostile ICU environment.

This retrospective-prospective longitudinal observational study was designed to evaluate the role of bedside lung ultrasound per se and in association with hemogasanalysis parameters in predicting the severity of COVID-19 patients in the Emergency Departement (ED). Retrospective data regarding patients who presented at the ED of IRCCS San Raffaele Hospital from 10/11/2020, together with those acquired by the observation of patients who will access to the ED until 10/05/2021 will be collected, configuring a total enrollment period of 6 months. Clinical informations about patients' medical history will be recorded, with particular focus on the type and date of onset of the symptoms. The diagnostic and therapeutic strategy will be chosen according to the current standard of care. Results of bedside lung ultrasound, together with vital parameters, blood gas analysis, laboratory and other findings will be recorded. The primary outcome will be defined as patients' outcome at time of discharge from the ED, in terms of intensity of required care (home discharge, low or high-intensity care hospitalization, death). Secondary outcomes will be patients' prognosis 30 days after access to ED and the required intensity of care (eg need for non-invasive ventilation, oro-tracheal intubation).The follow-up 30 days after access to the ED will be evaluated by telephone survey or by consulting medical records.

The new severe acute respiratory syndrome coronavirus 2019 (SARS-CoV-2) causes the illness named COVID-19, which is primarily characterized by pneumonia. As of 27 December, there have been over 79.2 million cases and over 1.7 million deaths reported since the start of the pandemic. In many cases, pneumonia evolves to acute respiratory distress syndrome (ARDS) with the need for mechanical ventilation and patient admission to intensive care unit, determining a marked increase in the need for intensive care beds worldwide. Pulmonary involvement causes predominantly hypoxemic respiratory failure. Although COVID-19 pneumonia often falls within the diagnostic criteria of ARDS, it differs from it for some peculiar pathophysiological characteristics. In particular, patients with ARDS secondary to COVID-19 often have the compliance of the respiratory system within the normal range. A significant role in the pathophysiology of hypoxemia seems to depend on vascular alterations such as altered pulmonary vascular self-regulation, pulmonary capillary leakage, and microvascular thrombosis in a complex process known as "immunothrombosis". All together they act by altering the relationship between ventilation and perfusion and increasing the dead space, which ultimately results in impaired efficiency of the pulmonary ventilation. Among the various markers associated with the prognosis of patients with COVID-19, D-dimer is linked to both the inflammatory state and thrombotic phenomena and could help to identify patients at greater risk of developing early ventilation-perfusion changes. This study aims at measuring the ventilatory efficiency, assessed by Ventilatory Ratio, in critically ill, mechanically ventilated, COVID-19 patients and its correlation with plasma D-dimer and quasi-static respiratory compliance.

Coronavirus disease 2019 (COVID-19) infection caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may manifest as a variety of disease patterns, ranging from mild to life-threatening pneumonia. Mucormycosis has been suspected to cause significant morbidity in infected people since the outbreak of the COVID-19 pandemic. Individuals who require hospitalization and intensive care are more vulnerable, as they have reached an advanced stage of their disease. Investigators will discuss the major risk factors, ocular presentation, and outcome of mucormycosis in individuals infected with SARS-CoV-2 in this study. From August 2021 to January 2022, a cross-sectional descriptive multicenter investigation would be conducted on patients with biopsy-confirmed mucormycosis and RTPCR confirmed COVID19. Demographic data, the time interval between COVID19 and mucormycosis, underlying systemic disorders, clinical characteristics, disease course, and outcomes would be analyzed.
