Purpose: Elastic light backscattering spectroscopy (ELBS) has exquisite sensitivity to the ultrastructural properties of tissue and thus has been applied to detect various diseases associated with ultrastructural alterations in their early stages. This study aims to test whether ELBS can detect early damage in retinal ganglion cells (RGCs). Methods: We used a mouse model of partial optic nerve crush (pONC) to induce rapid RGC death. We confirmed RGC loss by axon counting and characterized the changes in retinal morphology by optical coherence tomography (OCT) and in retinal function by full-field electroretinogram (ERG), respectively...

Importance: US hospitals receive financial penalties for excess risk-standardized 30-day readmissions and mortality in Medicare patients. Under current policy, readmission prevention is incentivized over 10-fold more than mortality reduction. Objective: To determine how penalties for US hospitals would change if policy equally weighted 30-day readmissions and mortality. Design, Setting, and Participants: Publicly available hospital-level data for fiscal year 2014 was obtained, including excess readmission ratio (ERR; risk-standardized predicted over expected 30-day readmissions) and 30-day mortality rates for heart failure, pneumonia, and acute myocardial infarction, as well as readmission penalties (as percent of Medicare Diagnosis Group payments)...

Tetramethylammonium tetraiodopentabromide [NMe4][I4Br5] was the first iodobromide synthesized and crystallized in an ionic liquid as well as in dichloromethane. The new iodobro-mides show different structure motives yet unknown from other nonahalides and can be better described as [(I2Br3)- · 2IBr]. The additional IBr units are connected by halogen-halogen interactions on the central V-shaped [I2Br3]-. The characterization was performed by Raman spectroscopy and single crystal X-ray structure determi-nation...

Differently from previous studies that used Transcranial Doppler (TCD) and functional MRI (fMRI) for cerebral vasomotor reactivity (CVR) assessment in patients with carotid stenosis (CS), we assessed CVR using an identical stimulus, the Breath-Holding Test (BHT). We included 15 patients with CS and 7 age-matched controls to verify whether fMRI responded differently to BHT between groups and to calculate the agreement rate between tests. For TCD, impaired CVR was defined when the mean percentage increase on middle cerebral artery velocities was ≤31% on 3 consecutive 30-s apnea intercalated by 4-min normal breathing intervals...

In 2010, South Africa launched a countrywide effort to scale up its voluntary medical male circumcision (VMMC) program on the basis of compelling evidence that circumcision reduces men's risk of acquiring HIV through heterosexual intercourse. Even though VMMC is free there, clients can incur indirect out-of-pocket costs (for example transportation cost or foregone income). Because these costs can be barriers to increasing the uptake of VMMC services, we assessed them from a client perspective, to inform VMMC demand creation policies...

Hydrogen is a key product of rumen fermentation and has been suggested to thermodynamically control the production of the various volatile fatty acids (VFA). Previous studies, however, have not accounted for the fact that only thermodynamic near-equilibrium conditions control the magnitude of reaction rate. Furthermore, the role of NAD, which is affected by hydrogen partial pressure (PH2), has often not been considered. The aim of this study was to quantify the control of PH2 on reaction rates of specific fermentation pathways, methanogenesis and NADH oxidation in rumen microbes...
