Filter by:This is a prospective observational study using a mobile study platform (app) that is designed for use on Android phones. Study participants will provide baseline demographic and medical information and report symptoms of respiratory infection on a weekly basis using the app. Participants will also report use of prevention techniques on the weekly survey. Mobility data will be collected passively using the sensors on the participant's smartphone, if the participant has granted the proper device permissions. The overall goals of the study are to track spread of coronavirus-like illness (CLI), influenza-like illness (ILI) and non-specific respiratory illness (NSRI) on a near-real time basis and identify specific behaviors associated with an increased or decreased risk of developing these conditions.
The first case of a person infected with SARS-Cov-2 virus can be tracked back on November the 17th, 2019, in China. On March 11, 2020, the World Health Organization (WHO) declared COVID-19 outbreak a pandemic. On April 13, COVID-19 is affecting 210 countries and territories worldwide, about 2 million positive cases have been officially declared along with 115.000 deaths. The real number of infected and deaths is scarily higher, considering that up to 65% people are asymptomatic and thus, not tested. The percentage of patients with COVID-19 needed for intensive care unit (ICU) varied from 5 to 32% in Wuhan, China. It was up to 9% in Lombardy, Italy. According to available data from Lombardy, 99% of patients admitted to the ICU needed respiratory support (88% invasive ventilation, 11% non invasive ventilation). The aim of the present investigation is to test the hypothesis whether transcutaneous partial O2 and CO2 pressures may be reliable predictive factors for acute respiratory distress syndrome (ARDS) development in hospitalized clinically stable COVID-19 positive patients and to clarify the role of the Angiotensin Converting Enzyme 2 (ACE2) and its final product, angiotensin 2 (Ang II) in the pathogenesis of this systemic disease. We also aim to test the hypothesis that plasma concentration of Clara Cell protein (CC16) and surfactant protein D (SPD), which are a biomarkers of acute lung injury, are severely decreased in COVID-19 positive patients and the plasma concentration is related to the severity of lung injury.
The present study is a randomized clinical trial, with the approval of the ethics committee will be conducted on patients who have a positive test confirming COVID-19 in Loghman Hakim Medical Education Center in Tehran. Patients will be randomly assigned to the two arms of the study and after completing the course of treatment and collecting and analyzing the necessary information from each patient, the results of the study will be published both on this site and in the form of an article in a reputable international journal.
Effectiveness of the use of Tenofovir/Emtricitabine in addition to personal protective equipment for the prevention of the transmission of SARS-COV-2 to health care personnel. A Randomized Clinical Trial. This is an experimental study whose aim is to evaluate the effectiveness of a drug to prevent infection with the virus that causes COVID-19 (SARS-CoV-2), in health care workers. The drug under study is Tenofovir /Emtricitabine, a well-known antiretroviral, which is safe and is used as prophylaxis and treatment for HIV and other viral infections such as Hepatitis. Several laboratory-based studies indicate that this drug has the potential to inhibit SARS-CoV-2 replication. In addition, one study in HIV infected persons found that those taking Tenofovir /Emtricitabine tended to have a lower occurrence of COVID-19. In this study, we will compare the occurrence of infection with SARS-CoV-2/ COVID19 in health care workers between those assigned to an intervention group and those assigned to a control group. The intervention group will receive Tenofovir /Emtricitabine during 60 days in addition to the use of personal protective equipment (PPE), and the control group will receive a placebo during 60 days in addition to the use of personal protective equipment (PPE). The study will recruit 950 health professionals above 18 and less than 70 years, working in the emergency room, COVID wards and intensive care units of seven hospitals in Colombia. To make the comparison groups very similar, the participants will be assigned through a random mechanism to either the intervention (475), or the control (475) groups. In order to prevent biases in the evaluation of the results, neither the participants nor the clinical investigators, data managers, analysts and support personnel will know which intervention the participants are receiving. To determine the occurrence of infection with the virus the study will use both molecular tests that detect the presence of viral genes in respiratory secretions, and serological tests that detect the response of the immune system to the virus. The study will evaluate also the safety of this drug determining the occurrence of adverse events.
Based on the experience of previous pandemics, countries reacted by applying different upgrade strategies to prevent or delay the widespread of the disease. Therefore, measures such as border closure, school closure, restrict social gathering (even shutdown of workplaces), limit population movements, and confinement meaning quarantines at the scale of cities or regions. In public hospitals, several measures have been decided to concentrate the power of care on potential wave of admissions of patients with severe forms of Covid-19. In this purpose, the number of available beds in Intensive Care Units (ICU) has been increased by two-fold and scheduled non-emergency surgical procedure have been cancelled. That means: 1. For the most severe patients, new personals (physician such as anesthesiologists, nurses of other units) have been transferred in ICUs. 2. For the less severe patients, personals of non-busy units have been transferred in busier ones. All these measures lead to major daily-life change sets that could be stressful. In the general population, it has been well documented that quarantine or confinement or isolation could lead to the occurrence of Post-Traumatic Stress Disorder (PTSD) syndrome in about 30% overall population. Importantly, high depressive symptoms have been reported in 9% of hospital staff. Numerous symptoms have been reported after quarantine or isolation such as emotional disturbance, depression, stress, low mood, irritability, insomnia, and post-traumatic stress symptoms. In hospital setting, few studies have been performed for assessing the psychological impact of quarantine and isolation. However, two studies reported a high prevalence of burn-out syndrome (BOS) in ICU physician and PTSD syndrome and depression in ICU nurses. As the consequences of all the measures decided and applied during Covid-19 pandemic could be important on caregivers, the present study primarily aims at assessing the prevalence of PTSD syndrome in a large population of caregivers implied or not in Intensive Care Units. The secondary objective were 1) to assess the prevalence of severe depression and anxiety and BOS 2) to isolate potential factors associated with PTSD, severe depression, anxiety or BOS.
Title: Phase I/II Trial (Safety and Dosing) of Povidone-iodine (PVP-I) Nasal Swab For Preventing COVID-19 Spread in Healthy Subjects: Summary: This study will evaluate in a PH I/II trial in healthy volunteers the safety and tolerability of PVP-I nasal swabs daily application. The intent is to follow with a PH III randomized controlled clinical trial to assess the capacity for PVP-I nasal swabs to mitigate the transmission of respiratory viruses specifically COVID 19.
The global escalation of COVID19 pandemic has put the health care system under pressure with urgent need for treatment. In the absence of vaccine and approved drug against SARS-COV2 over the past 6 months, the health authorities were obliged to re-purpose existing drugs to fight this pandemic.
Observational study to determine the optimal timing for surgery following SARS-CoV-2 infection and assess key global surgery indicators.
Low dose whole lung radiotherapy may improve survival of older patients with COVID-19 pneumonitis
The present study aimed to evaluate the accuracy of MSCT chest in the detection of COVID-19 cases and to correlate its diagnostic performance with that of the clinical presentation and CBC indices; using RT-PCR assays as a gold standard.
