Active clinical trials for "COVID-19"

Hip fracture in the elderly is a worldwide public health issue and a medical challenge for early postoperative rehabilitation. More than 2 million people are treated annually with an annual incidence between 100 and 300/100,000 (USA, Europe, China), resulting in a cost of billion dollars and a strain on most surgical facilities. In this context, an early surgical management of patient with fracture within the first 24-48h has been shown to reduce morbidity, length of hospital stay and mortality. During the Covid-19 pandemics, a higher risk of 30-day mortality has been reported in patients with pre-operative SARS-CoV-2 infection diagnosed 0-2 weeks, 3-4 weeks and 5-6 weeks before surgery compared with patients who did not have a pre-operative SARS-CoV-2 infection. However, this risk seems to disappear in patients diagnosed with SARS-CoV-2 ≥ 7 weeks before surgery. These findings led to propose delayed elective surgery when the benefit-risk ratio was acceptable (cancer, cardiac surgeries). However, delaying surgery in COVID-19 patients (with high risk of immune and thrombotic disorders) with hip fracture could be questionable as the risk related to COVID-19 could be counteracted by the risk delayed surgery. For assessing the mortality risk related to hip fracture surgery associated with COVID-19, we decided to use the French national hospital discharge records database for comparing the 30-day postoperative mortality in patients with hip fracture and with or without an hospitalization for SARS-COV-2 infection in the 30 previous days before surgery.

Retrospective observational cohort study. ToFCoMS: two years of follow-up of COVID-19 in MS.

The pathophysiology of SARS-COV-2 related respiratory disease is still poorly understood, especially in its most severe form called acute respiratory distress syndrome (ARDS). In this case, very few studies have investigated changes in gas exchange during COVID-19 progression in spontaneously breathing patients. The investigators purpose in this study to explore the pathophysiology of gas exchange and time course changes in spontaneously breathing patients with acute respiratory failure due to COVID-19. Moreover, our aim is to identify early markers associated with worsening respiratory failure and requiring endotracheal intubation.

Novel coronavirus disease (COVID-19), caused by Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, was first reported in December 2019 in Wuhan, China. The disease has spread to many countries in a few weeks and has become a global public health problem. By 2022, the virus has infected more than 500 million people worldwide and caused more than 6 million deaths. Case fatality rates (CFR) are an important index that helps to understand the epidemiological characteristics of an epidemic. In the data coming in 2020, COVID-19 CFR values were generally reported in the range of 0.001-0.706. However, from 2019 to 2022, there were 2 major changes that could affect the CFR of the disease. The first of these is vaccine applications, and the second is the new variants of SARS-CoV-2, which appeared first. From 2019 to 2022, it is likely that there will be a change in the mortality of COVID-19 in relation to both the vaccines administered and the new variants emerging. However, the data on this subject are not clear yet and more studies are needed. The aim of this study is to determine whether there is a change in the mortality of COVID-19 from 2019, when it first appeared, to 2022.

Recently, a study showed that markers of neutrophil extracellular traps formation, a mechanism corresponding to neutrophil activation, were increased in patients who died of COVID 19 compared with survivors. The investigators propose to analyze the NEU-SFL parameter, obtained automatically on the Sysmex™ blood count machine (Sysmex Corporation, Kobe, Japan) and which is considered as a reflect of neutrophil extracellular traps formation, in these two groups of patients. The aim was to evaluate whether this parameter could be used to predict the risk of death related to COVID 19.

Demographic, Clinical and laboratory data as well as outcome of total 202 COVID-19 patients who were Polymerase Chain Reaction (PCR) positive and admitted in Fatima memorial Hospital, Lahore, Pakistan, was collected during first and other waves. Data of First wave is from May 2020 to July 2020, second wave from early November to Mid December 2020 and third wave from Mid march to June 2021. Investigator analyzed the data on basis of Systemic immune inflammatory index (SII) as well hematological parameters of First Wave were compared to other waves of COVID-19.

Feedback: during the COVID-19 epidemic, access to operating theaters was restricted so that anesthetists and nurse anesthetists could reinforce the resuscitation workforce. The MEOPA was used as an alternative to sedation, allowing colonoscopies to be carried out, colon polyps and colorectal cancers to be detected.

The coronavirus 2019 pandemic (COVID-19) strongly affected clinical care worldwide. Due to a shortage of hospitals and beds in intensive care units (ICU), in Italy during outbreaks, surgical resources were temporarily and partially shifted to COVID-19 patients. In addition, the risk of cross-infection could have determined a shit in surgical perioperative care. To counterbalance these limitations, many centers routinely changed their clinical practice, which could be maintained by surgeons across Italy. The aim of the present study is to evaluate how the COVID-19 pandemic determined a change in daily clinical practice among all specialties.

This study is a prospective observational study that compares the anticoagulant therapy decision time among moderate and severe COVID-19 patients whose coagulation profiles were tested with thromboelastography (TEG) to those with a standard coagulation profile laboratory examination.

The main goal of this study was to understand the perceptions of nurses who cared for patients with Covid-19 at the onset of the pandemic in Northeast USA. Private interviews were held three times with each participant, over the period of 18 months. The interviews were examined for common themes and expressions used by nurses to describe such topics as their professional image, memories, and advise to other nurses.
