Acute respiratory distress syndrome (ARDS) is the most advanced form of acute lung injury (ALI). This is characterized by bilateral pulmonary infiltrates and severe hypoxemia. According to Berlin definition of ARDS, this is defined based on the timings, radiographic changes, edema formation, and severity on the PaO2 /FiO2 ratio. During ARDS, the loss of integrity of the epithelium causes the septic shock. The degree of epithelial injury is the major prognostic marker of ARDS. In addition to this, inflammatory cell migration, fibro-proliferation, and activation of apoptosis also play an important role in the pathophysiology of ARDS...

Veno-venous extracorporeal membrane oxygenation (ECMO) can be a lifesaving therapy for patients with severe acute respiratory distress syndrome (ARDS). ECMO is a technically complex and challenging procedure and should therefore only be performed in specialized centers. Transporting ARDS patients to ECMO centers for treatment can be dangerous because of the risk of hypoxemia during transport. This raises the question if ECMO should not be already initiated in the transferring hospital before transport. Over a 5-year period, we studied ARDS patients who had been transported to our department by our mobile ECMO team for further treatment after ECMO had already been initiated at the referring hospital...

Middle East Respiratory Syndrome coronavirus (MERS-CoV) infections are associated with a significant mortality rate, and existing drugs show poor efficacy. Identifying novel targets/pathways required for MERS infectivity is therefore important for developing novel therapeutics. As an enveloped virus, translocation through the endolysosomal system provides one pathway for cellular entry of MERS-CoV. In this context, Ca2+ -permeable channels within the endolysosomal system regulate both the luminal environment and trafficking events, meriting investigation of their role in regulating processing and trafficking of MERS-CoV...

Middle East respiratory syndrome coronavirus (MERS-CoV) is a single-stranded RNA virus that causes severe respiratory disease in humans with a high rate of fatality. The binding of the receptor binding domain (RBD) of the spike (S) glycoprotein to dipeptidyl peptidase 4 (DDP4) is the critical step in MERS-CoV infection of a host cell. No vaccines or clinically applicable treatments are currently available for MERS-CoV. Therefore, rapid diagnosis is important for improving patient outcomes through prompt treatment and protecting against viral outbreaks...

The incidence of pulmonary manifestations of inflammatory bowel disease (IBD) appears to be much higher than previously assumed. In prospective studies, subclinical pulmonary interstitial infiltrates or pathological lung function were found in 40%-60% of IBD patients, both in children and adults. Pulmonary disorders can affect any part of the respiratory system, the most frequent pattern being inflammation of the large airways often associated with bronchiectasis. The differential diagnosis should include drug-related pulmonary disease and infectious causes when receiving immunosuppressive therapy...

A 1-year-old boy was infected with parainfluenza virus type 4a (PIV4a) during an influenza epidemic in January 2016. His body temperature was 38.2 °C on day 1 of the illness followed by an intermittent phase of 36.5 °C on days 2 and 3, and it rose again on day 3 and peaked at 39.6 °C on day 4, of which the fever pattern was reminiscent of an influenza case with biphasic fever. However, results of rapid influenza virus (IFV) antigen tests performed at the first clinical visit and during the second fever phase on day 4 were both negative...

The emergence of respiratory diseases, i.e., severe acute respiratory syndrome (SARS) epidemic in 2003, H1N1 influenza epidemic in 2011 and Middle East respiratory syndrome (MERS) outbreak, reiterated the significance of ventilation in buildings. The role of ventilation in removing exhaled airborne bio-aerosols and preventing cross infections has been multidisciplinary extensively studied after the SARS outbreak in 2003. The characteristics of droplet-borne, short-range airborne and long-range airborne transmission of infectious diseases were identified...

Background: Quick Sepsis-related Organ Failure Assessment (qSOFA) is a new screening system for sepsis. The prognostic performance of qSOFA for patients with suspected infections outside the intensive care unit (ICU) is similar to that of full SOFA; however, its performance for community-acquired pneumonia (CAP) has not yet been evaluated in detail.The objectives of the present study were to compare the prognostic performance of qSOFA with existing pneumonia severity scores, such as CURB-65 (confusion, blood urea nitrogen > 19 mg/dL, respiratory rate ≥ 30/min, systolic blood pressure < 90 mmHg, or diastolic blood pressure ≤ 60 mmHg, age ≥ 65 years) and the pneumonia severity index (PSI), and examine its usefulness for predicting mortality and ICU admission in patients with CAP of high severity and mortality that requires hospitalization...

The immune system has been traditionally divided into two arms called innate and adaptive immunity. Typically, innate immunity refers to rapid defense mechanisms that set in motion within minutes to hours following an insult. Conversely, the adaptive immune response emerges after several days and relies on the innate immune response for its initiation and subsequent outcome. However, the recent discovery of immune cells displaying merged properties indicates that this distinction is not mutually exclusive. These populations that span the innate-adaptive border of immunity comprise, among others, CD1d-restricted natural killer T cells and MR1-restricted mucosal-associated invariant T cells...

Feline calicivirus (FCV) is a major cause of upper respiratory tract disease in cats, with widespread distribution in the feline population. Recently, virulent systemic diseases caused by FCV infection has been associated with mortality rates up to 50%. Currently, there are no direct-acting antivirals approved for the treatment of FCV infection. Here, we tested 15 compounds from different antiviral classes against FCV using in vitro protein and cell culture assays. After the expression of FCV protease-polymerase protein, we established two in vitro assays to assess the inhibitory activity of compounds directly against the FCV protease or polymerase...

Botulinum neurotoxin (BoNT) serotypes A, B and E are responsible for most cases of human botulism. The only approved therapy for botulism is antitoxin treatment administered to patients after symptom onset. However, a recent meta-analysis of antitoxin efficacy in human botulism cases over the last century concluded that a statistically significant reduction in mortality is associated with the use of type-E and type-A but not type-B antitoxin. Animal models could be highly valuable in studying post-symptom antitoxin efficacy (PSAE)...

In April 2017, the U.S. Food and Drug Administration granted regular approval to midostaurin for the treatment of adult patients with aggressive systemic mastocytosis (ASM), systemic mastocytosis with associated hematological neoplasm (SM-AHN), or mast cell leukemia (MCL). Approval was based on results from CPKC412D2201, a single-arm trial of midostaurin (100 mg orally twice daily) in previously treated or untreated patients. For the patients with ASM and SM-AHN, efficacy was established on the basis of confirmed complete remission (CR) plus incomplete remission (ICR) by modified Valent criteria with six cycles of midostaurin...

BACKGROUND: Although cardio-respiratory (CR) system is generally controlled by the autonomic nervous system, interactions between the cortex and these primary functions are receiving an increasing interest in neurosciences. NEW METHOD: In general, the timing of such internally paced events (e.g. heartbeats or respiratory cycles) may display a large variability. For the analysis of such CR event-related EEG potentials, a baseline must be correctly associated to each cycle of detected events...
