#1
E H Davies, E Fulton, D Brook, D A Hughes
The success of the Regulation on Orphan Medicinal Products in the European Union is evidenced by the 127 orphan drugs that have had market authorisation since 2000. However the incentives aimed to stimulate research and development have had the unintended consequence of increasing drug cost, resulting in many orphan drugs not being cost-effective. Orphan drugs command an increasing share of the pharmaceutical market and account for a disproportionate amount of healthcare expenditure. Orphan drug ownership by socially motivated, not-for-profit organisations may facilitate access to more affordable orphan drugs, for the benefit of patients and healthcare systems alike...

Frequent utilization of emergency department (ED) services contributes substantially to the cost of healthcare nationally and is often driven by psychiatric factors. Using national-level data from the Veterans Health Administration (VHA), the present study examined patient-level factors associated with ED use among veteran psychiatric patients. Veterans who had at least one ED visit with a psychiatric diagnosis in fiscal years 2011-2012 (n = 226,122) were identified in VHA administrative records. Andersen's behavioral model of healthcare utilization was used to identify need, enabling, and predisposing factors associated with frequency of ED use (primary outcome) in multivariate regression models...

BACKGROUND: Positional obstructive sleep apnea (POSA) is common in mild and moderate forms of obstructive sleep apnea (OSA). Two smartphone applications (apps) professing to avoid the supine position (SP) are available: for Android the "Apnea Sleep Position Trainer" and for iOS the "SomnoPose-Sleep Position Monitor". The smartphone needs to be attached to the chest to recognize SP, which then triggers a vibration alarm. This is intended to encourage the patient to change position and the vibration stops as soon as SP is left...

OBJECTIVES: The BASHH guidelines recommend molecular tests to aid diagnosis of Trichomonas vaginalis (TV) infection; however many clinics continue to use relatively insensitive techniques (pH, wet-prep microscopy (WPM) and culture). Our objectives were to establish a laboratory pathway for TV testing with the Becton-Dickinson Qx (BDQx) molecular assay, to determine TV prevalence and to identify variables associated with TV detection. METHODS: A prospective study of 901 women attending two urban sexual health services for STI testing was conducted...

We introduce a new concept that utilizes cognate nucleic acid nanoparticles which are fully complementary and functionally-interdependent to each other. In the described approach, the physical interaction between sets of designed nanoparticles initiates a rapid isothermal shape change which triggers the activation of multiple functionalities and biological pathways including transcription, energy transfer, functional aptamers and RNA interference. The individual nanoparticles are not active and have controllable kinetics of re-association and fine-tunable chemical and thermodynamic stabilities...

Allogeneic hematopoietic cell transplantation (alloHCT) conditioning regimen intensity has varied for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). A comparative effectiveness analysis was performed to assess outcomes of busulfan and fludarabine (BuFlu) versus fludarabine and 400 cGy total body irradiation (FluTBI) conditioning. Thirty-three subjects received BuFlu and 38 had FluTBI. The BuFlu group received more red blood cell transfusions (P=0.02) and had a longer time to platelet recovery (P=0...

INTRODUCTION: The phenotypic frailty (PF) model (including slow walking, low physical activity, exhaustion, weakness, and unintentional weight loss) has been widely used to quantify the degree of frailty and predict risks of adverse health outcomes for the elderly. However, evidence has shown that not all the components included in the PF model contribute equally, and low predictive accuracy of the PF model has been reported in predicting risks of outcomes. We aimed to improve predictive accuracy of the PF model in risk of major osteoporotic fracture (MOF) in the elderly by modifying its weighting of individual components...

Increasing use of engineered nanoparticles (NPs) in many industrial processes and consumer products requires rapid analytical methodologies to reliably detect and screen samples for the presence of NPs. Here, we report the development, analytical characterization and performance evaluation of a colorimetric assay as a comprehensive test for quantitative detection, screening and reactivity evaluation of nanoceria (cerium oxide, CeO2) particles in aqueous environments. We provide a critical discussion of the role of environmental conditions including pH, ionic composition, and presence of humic acid and particle type on the overall performance and sensitivity of this assay...

In this study, we introduce a modulation strategy for comprehensive two-dimensional gas chromatography (GC×GC) by using a simple and consumable-free modulator. This "Do-It-Yourself" interface comprised a 1.0m×0.25mm segment of MTX-5 metallic column and a low-cost DC power supply. Thermal desorption modulation (TDM) was attained using a dual-stage heater-based modulator in a novel segmented-loop configuration. TDM was achieved by alternating analyte trapping and thermal desorption. Former process relied on analyte partition to sorbent phase, while latter explored direct resistive heating...

Fusarium mycotoxins such as trichothecenes, zearalenone and fumonisins occur on a worldwide basis in cereal grains, animal feeds and forages. Practical solutions for multiple mycotoxin determination in samples are required by industry and regulators for cost effective screening purposes. The feasibility of developing a novel multiplex nanoarray for the simultaneous and semi-quantitative detection of three regulated mycotoxins: zearalenone (ZEA), T2-toxin (T2) and fumonisin B1 (FUM) was examined. Additionally, the assay was also able to detect HT2 toxin and fumonisin B2 and B3 due to the cross reactivity profiles of the antibodies used...

Due to lack of suitable bioanalytical methods in previous literature, for simultaneous estimation of Vitamin K1 isomers, in compliance with the current regulatory expectation, we aimed to develop a sensitive and rapid method with UFLC-APCI-MS/MS (ultrafast liquid chromatography - tandem mass spectrometry) using human plasma. A simple and cost effective procedure was implemented with the combination of protein precipitation and liquid extraction, to isolate the targets from plasma sample, while achieving an insignificant matrix effects and high recovery (≥88...

Ovine psoroptic mange (sheep scab) is a debilitating and damaging condition caused by a hypersensitivity reaction to the faecal material of the parasitic mite Psoroptes ovis. Farmers incur costs from the use of prophylactic acaricides and, if their sheep become infected, they incur the costs of therapeutic treatment plus the economic loss from reduced stock growth, lower reproductive rate, wool loss and hide damage. The unwillingness of farmers to use routine prophylactic treatment has been cited as a primary cause of the growing incidence of sheep scab in the United Kingdom (UK) since the disease was deregulated in 1992...

BACKGROUND: Opioid agonist therapy using methadone, an effective treatment of opioid use disorders (OUD) for people who inject drugs (PWID), is recommended by the World Health Organization as essential to curtail the growing HIV epidemic. Yet, despite increasing prevalence of OUD and HIV, methadone therapy has not yet been implemented in Russia. The aim of this modeling study was to estimate the cost-effectiveness of methadone therapy for Russian adults with a diagnosed OUD. METHODS/DESIGN: We modeled the projected program implementation costs and estimated disability-adjusted life years (DALYs) averted over a 10-year period, associated with the provision of methadone therapy for a hypothetical, unreplenished cohort of Russian adults with an OUD (n = 249,000), in comparison to the current therapies at existing addiction treatment facilities...

BACKGROUND: Next Generation Genome sequencing techniques became affordable for massive sequencing efforts devoted to clinical characterization of human diseases. However, the cost of providing cloud-based data analysis of the mounting datasets remains a concerning bottleneck for providing cost-effective clinical services. To address this computational problem, it is important to optimize the variant analysis workflow and the used analysis tools to reduce the overall computational processing time, and concomitantly reduce the processing cost...

MOFs have attracted significant attention as solid sorbents in gas separation processes for low-energy post-combustion CO2 capture. The parasitic energy (PE) has been put forward as a holistic parameter that measures how energy efficient (and therefore cost-effective) the CO2 capture process will be using the material. In this work, we present a nickel isonicotinate based ultra-microporous MOF, 1 [Ni-(4PyC)2⦁DMF], that has the lowest PE for post-combustion CO2 capture reported to date. We calculate a PE of 655 kJ/kg CO2, which is lower than that of the best performing material previously reported, Mg-MOF-74...

The detection and prediction of changes in coastal ecosystems require a better understanding of the complex physical, chemical and biological interactions, which involves that observations should be performed continuously. For this reason, there is an increasing demand for small, simple and cost-effective in situ sensors to analyze complex coastal waters at a broad range of scales. In this context, this study seeks to explore the potential of beam attenuation spectra, c(λ), measured in situ with an advanced-technology optical transmissometer, for assessing temporal and spatial patterns in the complex estuarine waters of Alfacs Bay (NW Mediterranean) as a test site...
