NLR has previously been observed to correlate with complications in upper GI (1) and colorectal (2) surgery. The investigators sought to assess if a similar correlation can be identified in emergency general surgical patients and if the presence of suspected or confirmed COVID-19 may impact on this. Given the heterogeneity of emergency general surgery the investigators therefore plan to perform a retrospective review of patients having emergency laparotomies only at a single NHS site during COVID-19 pandemic. Assessment of outcomes and Neutrophil:lymphocyte ratio as a predictor of outcomes will be completed. Outcomes will be completed in line with the recent COVIDSurg study criteria (3). The primary outcome is 30-day mortality. Secondary outcomes are 7-day mortality, re-operation, length of stay, post-operative respiratory failure, post-operative ARDS (Acute Respiratory Distress Syndrome), post-operative sepsis and ITU (Intensive Therapy Unit)/HDU (High Dependency Unit) admission.
The purpose of this study is to assess the efficacy of N-acetylcysteine (NAC) in preventing those with mild or moderate COVID-19 from progressing to severe disease
The prevalence and typical patterns of neurological complications in hospitalized COVID-19 patients admitted to the intensive care units of the University Hospital Zurich will be investigated. The impact of neurological complications among COVID-19 patients on mortality, functional outcome, and organizational outcomes will be analyzed.
The aim of this study is to capture data, laboratory markers, and clinical outcomes of obstetric and neonatal outcomes in cases of COVID-19 during pregnancy and of pregnancies exposed to a COVID-19 vaccine in Cuyahoga County.
This is an observational, prospective, non-randomized, non-significant risk study collecting voice recordings from subjects who are being tested for COVID-19 by laboratory analysis of specimens obtained by nasal or naso-pharyngeal (NP) swab. Patients record their voices through an app on their mobile phone. Patients and health care providers will be blinded to the swab test results during Phase 2 of the study.
The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which originated in Wuhan, China, has become a major concern all over the world. Convalescent plasma or immunoglobulins have been used as a last resort to improve the survival rate of patients with SARS whose condition continued to deteriorate despite treatment with pulsed methylprednisolone. Moreover, several studies showed a shorter hospital stay and lower mortality in patients treated with convalescent plasma than those who were not treated with convalescent plasma. Evidence shows that convalescent plasma from patients who have recovered from viral infections can be used effectively as a treatment of patients with active disease. The use of solutions enriched of antiviral antibodies has several important advantages over the convalescent plasma including the high level of neutralizing antibodies supplied. Moreover, plasma-exchange is expensive and requires large volumes of substitution fluid With either albumin or fresh frozen plasma, increasing the risk of cardiovascular instability in the plasma donor and in the recipient, which can be detrimental in a critically ill patient with COVID 19 pneumonia. The use of plasma as a substitution fluid further increases treatment costs and is associated with risk of infections, allergic reactions and citrate-induced hypocalcemia. Albumin is better tolerated and less expensive, but exchanges using albumin solutions increase the risk of bleeding because of progressive coagulation factor depletion. The aforementioned limitations of plasma therapy can be in part overcome by using selective apheresis methods, such as double-filtration plasmapheresis (DFPP)3. During DFPP, plasma is separated from cellular components by a plasma filter, and is then allowed to pass through a fractionator filter. Depending on the membrane cut-off, the fractionator filter retains larger molecules and returns fluid along with smaller molecules to the circulation. Thus, the selection of a membrane with an appropriate sieving coefficient for IgG allows to efficiently clear autoantibodies in patients with antibody-mediated diseases (e.g., macroglobulinemia, myasthenia gravis and rheumatoid arthritis) with negligible fluid losses and limited removal of albumin and coagulation factors1. In patients with severe membranous nephropathy and high titer of autoreactive, nephritogenic antibodies against the podocyte-expressed M type phospholipase A2 receptor (PLA2R), DFPP accelerated anti PLA2R depletion4. Measurement of the antibody titer in treated patient and recovered fluid showed that antibody removal was extremely effective and that large part of antibodies was removed during the first DFPP procedure. This therapeutic regimen was safe and well tolerated and easy to apply4. In an ongoing pilot study we found that the same methodological approach can be used to remove circulating antibodies from patients who recovered from COVID 19 and to infuse these antibodies in patients with active viral infection. Treatment was well tolerated and preliminary findings are encouraging. Thus, in this novel pilot study we aim to explore whether the infusion of antibodies obtained with one single DFPP procedure from voluntary convalescent donors could offer an effective and safe therapeutic option for patients with earlier stages of coronavirus (COVID-19) pneumonia requiring oxygen supply without mechanical ventilation.
There is currently no treatment available for COVID-19, the acute respiratory illness caused by the novel SAR-CoV-2. Convalescent plasma from patients who have recovered from COVID-19 that contains antibodies to the virus is a potential therapy. On March 25th, 2020, the FDA approved the use of convalescent plasma under the emergency investigational new drug (eIND) category. Randomized trials are needed to determine the efficacy and safety of COVID-19 convalescent plasma for acute COVID-19 infection. The objective of the CONCOR-1 trial is to determine the efficacy of transfusion of COVID-19 convalescent plasma to adult patients admitted to hospital with COVID-19 infection at decreasing the frequency of in-hospital mortality in patients hospitalized for COVID-19. It is hypothesized that treating hospitalized COVID-19 patients with convalescent plasma early in their clinical course will reduce the risk of death, and that other outcomes will be improved including risk of intubation, and length of ICU and hospital stay. WCM is a U.S. sub-site to this pan-Canadian clinical trial (NCT04348656) which has the potential to improve patient outcomes and reduce the burden on health care resources including reducing the need for ICU beds and ventilators.
The objective of this study is to obtain data on the efficacy of the Vielight RX Plus in decreasing time to recovery of symptoms in subjects with COVID-19. The study will be conducted among COVID-19 positive subjects at home in self-isolation via electronic data collection (EDC). There will be no physical contact between the subjects and the Qualified Investigator (QI) or other study staff. This study aims to demonstrate that the Vielight RX Plus is a useful adjunct to standard of care (SOC). We hypothesize that the Vielight RX Plus will accelerate recovery and reduce viral infection severity.
The objective of the COVID-HOP study is to identify biological and non-biological markers associated to: a positive or negative serology anti SRAS-Cov-2; a positive serology and having presented symptoms or, on the contrary, not having had symptoms; the persistence of immunity or the loss of this immunity over time; the protective nature of the presence of anti SRAS-Cov-2 antibodies. To answer these questions, a biological collection (serum, plasma, DNA, RNA, mono-nucleated cells and urine) and a collection of detailed clinical data during the serological screening for SARS-CoV-2 of hospital agents (medical and non-medical staff) of the Assistance Publique Hôpitaux de Paris (Paris, France) will be carried out. 4000 professionals in 5 hospitals will be included. As part of the research, the anti SRAS-CoV-2 serology will be monitored 6 months and 12 months after the initial serology. Numerous studies will be carried out from this biological collection and from the database to answer the primary and secondary endpoints.
