The effects of convalescent plasma (CP) infusion, one the treatment options for severe Middle East respiratory syndrome coronavirus (MERS-CoV) infections, have not yet been evaluated.Serological responses CP-infused MERS patients during 2015 Korean outbreak at a tertiary care centre were evaluated. Serological activity was evaluated with anti-MERS-CoV enzyme-linked immunosorbent assay (ELISA) immunoglobulin (Ig)G, ELISA IgA, immunofluorescence IgM and plaque reduction neutralization test...

Abstract Background Timely administration of antibiotics is one the most important interventions in reducing mortality sepsis. However, administering within a strict time threshold all patients suspected with sepsis will require huge amount effort and resources may increase risk unintentional exposure to broad-spectrum without infection its consequences. Thus, controversy still exists on whether clinicians should target different time-to-antibiotics thresholds for versus septic shock....

BackgroundAfter the 2015 Middle East respiratory syndrome (MERS) outbreak in Korea, prediction of pneumonia development and progression to failure was emphasized control MERS outbreak.MethodsMERS-CoV infected patients who were managed a tertiary care center during Korean reviewed. To analyze predictive factors for failure, we evaluated clinical variables measured within three days from symptom onset.ResultsA total 45 included study: 13 (28.9%) did not develop pneumonia, 19 developed without...

The role of extracorporeal membrane oxygenation (ECMO) remains controversial in adult patients with refractory septic shock. We sought to describe the clinical outcomes supported by ECMO during shock conventional treatment. analysed consecutive shock, assisted an system between January 2005 and December 2013 a single-centre registry. primary outcome was survival hospital discharge. A total 32 (21 males) received support for Of these, 14 (43.8%) had undergone cardiopulmonary resuscitation...

Background COVID-19, which is accompanied by acute respiratory distress, multiple organ failure, and death, has spread worldwide much faster than previously thought. However, at present, it limited treatments. Objective To overcome this issue, we developed an artificial intelligence (AI) model of named EDRnet (ensemble learning based on deep neural network random forest models), to predict in-hospital mortality using a routine blood sample the time hospital admission. Methods We selected 28...

For the clinical application of semi-quantitative anti-SARS-CoV-2 antibody tests, analytical performance and titer correlation plaque reduction neutralization test (PRNT) need to be investigated. We evaluated PRNT titer-correlation one surrogate virus (sVNT) kit three chemiluminescent assays. measured total antibodies for receptor-binding domain (RBD) spike protein, nucleocapsid protein (NP), IgG RBD. All assays showed high detection SARS-CoV-2 infection, with a sensitivity ≥ 98% specificity...

Background Sepsis‐induced cardiac dysfunction, known as septic cardiomyopathy, is a common complication associated with increased mortality. Cardiac troponins serve markers for myocardial injury and are frequently elevated in patients sepsis. However, the role of troponin elevation at sepsis recognition risk stratification remains controversial.

Physical therapy (PT) and early mobilization for critically ill patients have been popularized to decrease the length of hospital stay improve quality life after discharge. We reviewed our experience PT active on extracorporeal membrane oxygenation (ECMO) in terms its technical feasibility safety. Study endpoints were safety events during interruptions due unstable vital signs. Of eight patients, one patient (12.5%) had venoarterial ECMO, seven (87.5%) venovenous ECMO. Among total 62...

Phosphoinositide 3-kinases (PI3Ks) contribute to the pathogenesis of asthma by regulating activation inflammatory mediators, cell recruitment and immune function. Recent findings have indicated that PI3Ks also regulate expression interleukin (IL)-17, which has been recognised as an important cytokine involved in airway inflammation. In present study, we investigated a role PI3Kδ regulation IL-17 allergic disease using murine model asthma. After ovalbumin inhalation, administration selective...
