The inflammatory response of sepsis results in organ dysfunction, including myocardial dysfunction. Myocardial dysfunction is particularly important in patients with severe septic shock who progress to a hypodynamic pre-terminal phase. Multiple aspects of this septic inflammatory response contribute to the pathogenesis of decreased ventricular contractility. ⋯ Now new information suggests that the septic inflammatory response impairs normal depolarization by altering the cardiomyocyte sodium current. This results in decreased ventricular contractility. This is important because new targets for therapeutic intervention can be considered and new approaches to evaluation of this problem can be contemplated.

The newly emerging human pathogen influenza A H7N9 represents a potentially major threat to human health. The virus was first shown to be pathogenic in humans in 2013, and outbreaks continue to occur in China to the present time. ⋯ In the absence of an effective vaccine, targeted regulation of the host immune response by immune modulators might be considered. Readily available, approved drugs with immune-modulating activities might prove to be a treatment option in combination with existing antiviral agents and supportive care.

The predisposition, infection, response and organ dysfunction (PIRO) staging system was designed as a stratification tool to deal with the inherent heterogeneity of septic patients. The present study was conducted to assess the performance of PIRO in predicting multiple organ dysfunction (MOD), intensive care unit (ICU) admission, and 28-day mortality in septic patients in the emergency department (ED), and to compare this scoring system with the Mortality in Emergency Department Sepsis (MEDS) and Acute Physiology and Chronic Health Evaluation (APACHE II) scores. ⋯ The study indicates that PIRO is helpful for risk stratification and prognostic determinations in septic patients in the ED.

Randomized Controlled Trial Multicenter StudyInhaled Colistin in Patients with Bronchiectasis and Chronic Pseudomonas aeruginosa Infection.
Chronic infection with Pseudomonas aeruginosa is associated with an increased exacerbation frequency, a more rapid decline in lung function, and increased mortality in patients with bronchiectasis. ⋯ Although the primary endpoint was not reached, this study shows that inhaled colistin is a safe and effective treatment in adherent patients with bronchiectasis and chronic P. aeruginosa infection. Clinical trial registered with http://www.isrctn.org/ (ISRCTN49790596).
