Cerebrospinal fluid proteomics reveals the innate immunity and blood-brain barrier dysregulation in a patient with multidrug-resistant ventriculitis treated with intrathecal and intravenous polymyxin B.

is a major pathogen of nosocomial meningitis and ventriculitis. Due to very limited antibiotic treatment options, polymyxins are often used as a last-line therapy. To optimise polymyxin use in the intraventricular environment, cerebrospinal fluid (CSF) proteomics was employed to investigate host-pathogen-polymyxin interactions in a 69-year-old patient with multidrug-resistant ventriculitis treated with a combination of intrathecal (ITH; 50,000 IU q24h/q48h), intraventricular (IVT; 50,000 IU q48h), and intravenous (500,000 IU, q12h) polymyxin B.

Establishing bio-logging data collections as dynamic archives of animal life on Earth.

Rapid growth in bio-logging-the use of animal-borne electronic tags to document the movements, behaviour, physiology and environments of wildlife-offers opportunities to mitigate biodiversity threats and expand digital natural history archives. Here we present a vision to achieve such benefits by accounting for the heterogeneity inherent to bio-logging data and the concerns of those who collect and use them. First, we can enable data integration through standard vocabularies, transfer protocols and aggregation protocols, and drive their wide adoption.

Examining Bi-directional links between distinct affect states and tobacco lapse during a cessation attempt.

Background: Theoretical models of addiction highlight the bi-directional links of certain distinct affect states and tobacco lapse, but to date, few studies have examined bi-directional associations, instead examining associations with global affect measures (e.g., negative affect versus feelings of guilt).

A novel concept of an acoustic ultrasound wearable for early detection of implant failure.

Mechanical failure of medical implants, especially in orthopedic poses a significant burden to the patients and healthcare system. The majority of the implant failures are diagnosed at very late stages and are of mechanical causes. This makes the diagnosis and screening of implant failure very challenging.
