Supersaturated silica-lipid hybrids have previously demonstrated improved in vitro solubilisation and in vivo oral bioavailability of poorly water-soluble drugs, however were only fabricated using a single lipid (LFCS type I formulations) and were not compared to their liquid precursors. This study investigated the influence of lipid formulation classification (type I vs. type II vs. type IIIA/SNEDDS) and physical state (liquid LBF vs. solidified with silica) on the in vitro solubilisation of the poorly soluble, weak base, anti-psychotic drug, blonanserin (BLON), from a supersaturated lipid-based formulation (LBF). Stable liquid supersaturated LBF were fabricated using BLON (loaded at 150% of its equilibrium solubility), and solidified through encapsulation within porous silica microparticles at a 11 ratio. Their physicochemical properties and in vitro solubilisation during lipolysis were compared. Supersaturated BLON was encapsulated in the non-crystalline form. All supersaturated LBF improved the solubilisation of pure BLON during lipolysis regardless of their lipid formulation type or their physical state (1.7- to 13.4-fold). SNEDDS achieved greater solubilisation than the type II formulations (1.4- to 1.7-fold). Furthermore, the liquid precursors achieved greater solubilisation than the silica solidified formulations (4.5- to 5.7-fold). Additionally, in an attempt to increase BLON solubilisation, a spray-dried SNEDDS and dual-loaded solidified super-SNEDDS solidified with silica pre-loaded with BLON was developed, however did not significantly improve solubilisation. Liquid SNEDDS were identified as the optimal oral supersaturated LBF strategy for BLON based on in vitro lipolysis studies. Solidification of LBF using silica is a viable strategy for improving stability, however for drugs such as BLON, solidification may impede in vitro release and solubilisation.
Intraventricular vancomycin is an effective treatment for neonatal ventriculitis, as the cerebrospinal fluid (CSF) vancomycin levels reach adequate concentrations to achieve microbiological cure. There is no robust data on intraventricular vancomycin pharmacokinetics in the preterm population. This pilot population pharmacokinetic modelling study examines the pharmacokinetic behaviour of intraventricular vancomycin in the preterm population of < 28 weeks gestation, to inform the feasibility of future prospective studies.

The study comprised 8 preterm infants with neonatal ventriculitis (median gestation age 25.3weeks; range 23.9 - 27.7). Wnt inhibitor Population pharmacokinetics (non-linear mixed effects modelling) were described with one- and two-compartment models to fit plasma concentrations of vancomycin. A CSF compartment was added to the plasma modelling and mass transfer examined. Three covariates (serum creatinine, ventricular index (VI) and CSF protein) were tested on the final model. Area under the curve (cular vancomycin treatment in the preterm population, such as the current use of VI as a dosing parameter. Further study with a larger data pool is necessary to investigate the influence of VI on CSF vancomycin and ascertain dosing strategies.
Acute Respiratory Distress Syndrome (ARDS) is associated with increased pulmonary-vascular permeability. In the lung, transient receptor potential vanilloid 4 (TRPV4), a Ca
-permeable cation channel, is a regulator of endothelial permeability and pulmonary edema. We performed a Phase I, placebo-controlled, double-blind, randomized, parallel group, proof-of-mechanism study to investigate the effects of TRPV4 channel blocker, GSK2798745, on pulmonary-vascular barrier permeability using a model of lipopolysaccharide (LPS)-induced lung inflammation.

Healthy participants were randomized 11 to receive 2 single doses of GSK2798745 or placebo, 12h apart. Two hours after the first dose, participants underwent bronchoscopy and segmental LPS instillation. Total protein concentration and neutrophil counts were measured in bronchoalveolar lavage (BAL) samples collected before and 24h after LPS challenge, as markers of barrier permeability and inflammation, respectively. The primary endpoint was baseline adjusted totandothelial cells by ~70-85% during the 24h after LPS challenge; median urea-corrected BAL concentrations of GSK2798745 were 3.0- to 8.7-fold higher than those in plasma.

GSK2798745 did not affect segmental LPS-induced elevation of BAL total protein or neutrophils, despite blood and lung exposures that were predicted to be efficacious. CLINICALTRIALS.

To determine diagnoses and image features that are associated with difficult prepubescent female genital image interpretations.

This was a mixed-methods study conducted at a tertiary care pediatric center using images from a previously developed education platform.

Participants comprised 107 medical students, residents, fellows, and attendings who interpreted 158 cases to derive case difficulty estimates.

This was a planned secondary analysis of participant performance data obtained from a prospective multi-center cross-sectional study. An expert panel also performed a descriptive review of images with the highest frequency of diagnostic error.

We derived the proportion of participants who interpreted an image correctly, and features that were common in images with the most frequent diagnostic errors.

We obtained 16,906 image interpretations. The mean proportion correct scores for each diagnosis were as follows normal/normal variants 0.84 (95% confidence interval [CI] 0.82, 0.87); infectious/dermatology pathology 0.59 (95% CI 0.45, 0.73); anatomic pathology 0.61 (95% CI 0.41, 0.81); and, traumatic pathology 0.64 (95% CI 0.49, 0.79). The mean proportion correct scores varied by diagnosis (P<.001). The descriptive review demonstrated that poor image quality, infant genitalia, normal variant anatomy, external material (eg, diaper cream) in the genital area, and nonspecific erythema were common features in images with lower accuracy scores.

A quantitative and qualitative examination of prepubescent female genital examination image interpretations provided insight into diagnostic challenges for this complex examination. These data can be used to inform the design of teaching interventions to improve skill in this area.
