OBJECTIVES: Generic and disease-specific health-related quality of life (HRQoL) instruments may reflect different aspects of lives in patients with Parkinson's disease (PD) and thus be associated with different determinants. We used the same cluster of predictors for the generic and disease-specific HRQoL instruments to examine and compare the determinants of HRQoL. METHOD: HRQoL was measured in 92 patients with PD by the 36-item Short-Form Health Survey (SF-36) and the 39-item Parkinson's Disease Questionnaire (PDQ-39)...

In intracardiac echocardiography (ICE) it may be beneficial to generate ultrasound images acquired at multiple frequencies, having the possibility of high penetration or high-resolution imaging in a single device. The objective of the presented work is to test two frequency-tunable probe prototypes in a preclinical setting: a rigid probe having a diameter of 11 mm and a new flexible and steerable 12-Fr ICE catheter. Both probes feature a forward-looking 32-element capacitive micromachined ultrasonic transducer array (aperture of 2 × 2 mm(2)) operated in collapse mode, which allows for frequency tuning in the 6-MHz-18-MHz range...

A century-old tenet in physics and engineering asserts that any type of system, having bandwidth Δω, can interact with a wave over only a constrained time period Δt inversely proportional to the bandwidth (Δt·Δω ~ 2π). This law severely limits the generic capabilities of all types of resonant and wave-guiding systems in photonics, cavity quantum electrodynamics and optomechanics, acoustics, continuum mechanics, and atomic and optical physics but is thought to be completely fundamental, arising from basic Fourier reciprocity...

BACKGROUND: The growing menace of poor quality and falsified drugs constitutes a major hazard, compromising healthcare and patient outcomes. Efforts to assess drug standards worldwide have almost exclusively focused on anti-microbial drugs; with no study to date on cardiovascular drugs. Our study aims to assess quality of seven routinely used cardiovascular medications (anticoagulants, antihypertensives and statins) in ten Sub-Saharan African countries. METHODS: Drugs were prospectively collected using standardized methods between 2012 and 2014 from licensed (random pharmacies) and unlicensed (street-markets) places of sale in Africa...

BACKGROUND: Several patient-reported outcome measures (PROMs) have been used in studies of Rheumatoid Arthritis (RA). Most of these assess health-related quality of life (HRQL). The exception is the Rheumatoid Arthritis Quality of Life questionnaire (RAQoL). This scale measures the impact of RA and its treatment from the patient's perspective, making it suitable for determining the value patients gain from interventions. OBJECTIVE: This review collates literature reporting on the efficacy of the RAQoL as a measure of patient value in clinical studies...

Colloidal particles can act as vectors of adsorbed pollutants in the subsurface, or be themselves pollutants. They can reach the aquifer and impair groundwater quality. The mechanisms of colloid transport and deposition are often studied in columns filled with saturated porous media. Time-lapse profiles of colloid concentration inside the columns have occasionally been derived from magnetic resonance imaging (MRI) data recorded in transport experiments. These profiles are valuable, in addition to particle breakthrough curves (BTCs), for testing and improving colloid transport models...

PURPOSE: Health-related quality of life (HRQoL) is a widely used concept in the assessment of health care. Some generic HRQoL instruments, based on specific algorithms, can generate utility scores which reflect the preferences of the general population for the different health states described by the instrument. This study aimed to investigate the relationships between utility scores and potentially associated factors in patients with mental disorders followed in inpatient and/or outpatient care settings using two statistical methods...

Fatigue is a common and debilitating symptom, affecting 42-89% of end-stage kidney disease patients, persisting even in pre-dialysis care and stable kidney transplantation, with huge repercussions on functioning, quality of life and patient outcomes. This paper presents a critical review of current evidence for the role of psychological factors in renal fatigue. To date, research has concentrated primarily on the contribution of depression, anxiety and subjective sleep quality to the experience of fatigue. These factors display consistent and strong associations with fatigue, above and beyond the role of demographic and clinical factors...

BACKGROUND: It is widely acknowledged that concerns for the worse off need to be integrated with the concern for cost effectiveness in priority setting, and several countries are seeking to do so. In Norway, a comprehensive framework for priority setting was recently proposed to specify the worse off in terms of lifetime loss of quality-adjusted life-years (QALYs). However, few studies have shown how to calculate such health losses, how to integrate health loss into cost-effectiveness analyses (CEAs) and how such integration impacts the incremental cost-effectiveness ratios (ICERs)...

Wasim Ahmed, Jorge Rodríguez
In this work, a generalized method for the estimation of biokinetic parameters in anaerobic digestion (AD) models is proposed. The method consists of a correlation-based approach to estimate specific groups of parameters mechanistically, followed by a sensitivity-based hierarchical and sequential single parameter optimisation (SHSSPO) calibration method for the remaining groups of parameters. The method was evaluated to estimate and calibrate the parameter values for sulfate reduction processes when included into the IWA Anaerobic Digestion Model No...

The US Patient Protection and Affordable Care Act (ACA) aims to expand health care coverage, contain costs, and improve health care quality. Accessibility and affordability of innovative biopharmaceuticals are important to the success of the ACA. As it is substantially more difficult to manufacture them compared with small-molecule drugs, many of which have generic alternatives, biologics may increase drug costs. However, biologics offer demonstrated improvements in patient care that can reduce expensive interventions, thus lowering net health care costs...
