Risk factors of central catheter bloodstream infections in intensive care units: A systematic review and meta-analysis

Plos.org 

by Huayong Huang, Qiaoling Chang, Yanhui Zhou, Li Liao

Background

Central catheter bloodstream infections (CRBSI) is a major cause of healthcare-associated infections. However, few factors are generally accepted and some studies have conflicting finding about some factors, possibly caused by limitation associated with an individual study. This study was to identify risk factors for CRBSI in intensive care units.

Methods

We searched the PubMed, Cochrane Library, Web of science and... Читать дальше...

Collective search in ants: Movement determines footprints, and footprints influence movement

Plos.org 

by Stefan Popp, Anna Dornhaus

Collectively searching animals might be expected to coordinate with their groupmates to cover ground more evenly or efficiently than uncoordinated groups. Communication can lead to coordination in many ways. Previous work in ants suggests that chemical ‘footprints’, left behind by individuals as they walk, might serve this function by modulating the movement patterns of following ants. Here, we test this hypothesis by considering the two predictions that, first... Читать дальше...

Khat consumption and undernutrition among adult population in Ethiopia: A systematic review and meta-analysis

Plos.org 

by Abdu Oumer

Background

In Ethiopia, malnutrition is a public health threat causing a significant burden of morbidity, mortality, and economic crisis. Simultaneously, khat consumption is alarmingly increasing among adults, yet it might contribute to the existing burden of malnutrition, where the current evidence is inconclusive. Hence, this review was to estimate the association between khat consumption and undernutrition among adults in Ethiopia.

Gaussian accelerated molecular dynamics simulations facilitate prediction of the permeability of cyclic peptides

Plos.org 

by Nicolas Frazee, Kyle R. Billlings, Blake Mertz

Despite their widespread use as therapeutics, clinical development of small molecule drugs remains challenging. Among the many parameters that undergo optimization during the drug development process, increasing passive cell permeability (i.e., log(P)) can have some of the largest impact on potency. Cyclic peptides (CPs) have emerged as a viable alternative to small molecules, as they retain many of the advantages of small molecules (oral availability... Читать дальше...

How does the online innovation community climate affect the user’s value co-creation behavior: The mediating role of motivation

Plos.org 

by Qiong Tan, Juan Tan, Xiaohui Gao

Online Innovation Community (OIC) serves as a virtual space for users to exchange products and services, and share knowledge and information. Previous studies have indicated that community climate is an important factor affecting users’ value co-creation behavior, however, the influencing process has not been clearly revealed from the perspective of motivation. In this study, we explored the relationship between online innovation community climate (supportive climate and controlling climate)... Читать дальше...

Predictive coding in musical anhedonia: A study of groove

Plos.org 

by Peter Benson, Nicholas Kathios, Psyche Loui

Groove, or the pleasurable urge to move to music, offers unique insight into the relationship between emotion and action. The predictive coding of music model posits that groove is linked to predictions of music formed over time, with stimuli of moderate complexity rated as most pleasurable and likely to engender movement. At the same time, listeners vary in the pleasure they derive from music listening: individuals with musical anhedonia report... Читать дальше...

Nearly a year since it was first announced, Anker is finally selling its Solix whole-home battery backup solution in North America. The Solix X1 is just 5.9 inches thick and attaches to a wall like a Tesla Powerwall. It’s a more permanent and minimalist alternative to Anker’s modular F3800 kits, which can be quickly detached to power a weekend away.
