Interactions between insomnia, sleep duration and emotional processes: An ecological momentary assessment of longitudinal influences combining self-report and physiological measures.

Previous studies indicated that further investigation is needed to understand how insomnia disorder interacts with emotional processes. The present study is an ecological momentary assessment evaluating the link between emotional and sleep alterations in patients with insomnia. Physiological (heart rate and heart rate variability) and subjective (sleep and emotions) indices were observed for 5 days in patients with insomnia disorder (n = 97), good sleepers under self-imposed sleep restriction (n = 41), and good sleepers with usual amount of sleep (n = 45).

High-throughput screening for high-efficiency small-molecule biosynthesis.

Systems metabolic engineering faces the formidable task of rewiring microbial metabolism to cost-effectively generate high-value molecules from a variety of inexpensive feedstocks for many different applications. Because these cellular systems are still too complex to model accurately, vast collections of engineered organism variants must be systematically created and evaluated through an enormous trial-and-error process in order to identify a manufacturing-ready strain. The high-throughput screening of strains to optimize their scalable manufacturing potential requires execution of many carefully controlled, parallel, miniature fermentations, followed by high-precision analysis of the resulting complex mixtures.

Contrast-Enhanced Ultrasound for the Detection of Abdominal Complications in Infective Endocarditis: First Experience From a Prospective Cohort.

Embolic events are associated with increased mortality in patients with infective endocarditis (IE). The goal of this study was to gain experience with the application of contrast-enhanced ultrasound (CEUS) in IE to detect abdominal complications. CEUS was performed in 40 patients from a prospective register of IE.

Diagnostic challenges in infective endocarditis: is PET/CT the solution?

Purpose: Despite developments in both imaging and microbiological techniques, the final diagnosis of IE often remains challenging. In this single-center cohort study, we aimed to identify the specific indications for request of F-FDG-PET/CT in clinical practice and to evaluate the diagnostic benefit of this nuclear imaging technique.

Methods: A total of 235 patients with possible (n = 43) or definite (n = 192) IE according to the revised Duke criteria were prospectively studied from July 2013 until December 2016.
