This article describes four older adults with Alzheimer's disease and comorbidities who used an automatic medication dispenser (AMD) to continue pharmacotherapy for these chronic diseases and who remained at home living either alone or with an older spouse. The AMDs were used for 3 to 4.5 years. The patients scored at least 21 on the Mini-Mental State Examination, and their dosing regimen involved taking the medication once or twice per day throughout this period. The caregivers filled the devices with medications once every 1 to 2 weeks and continuously monitored the patients' conditions nearly every day...

In recent years, the relationship between vitamin D and health has received growing attention from the scientific and medical communities. Vitamin D deficiencies have been repeatedly associated with various acute and chronic diseases, including age-related macular degeneration (AMD). Its active metabolite, 1α,25-dihydoxy vitamin D, acts as a modulator of cell proliferation, differentiation and apoptosis, and cumulative data from experimental and observational studies suggest that relatively a lower vitamin D status could be a potential risk factor for the development of early and/or late AMD...

PURPOSE: The aim of this study was to evaluate the effect of intravitreal injection of aflibercept (IVA) on blood coagulation tests in neovascular age-related macular degeneration (AMD) patients. METHODS: Thirty-four patients with neovascular AMD (study group) and 32 healthy individuals (control group) were enrolled. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were measured at different times in patients with neovascular AMD. RESULTS: The levels of PT and aPTT after IVA were decreased at 1 month after the first injection and 1 month after the second injection compared to the baseline measurement in the study group...

Treatment of neovascular age-related macular degeneration (AMD) with anti-vascular endothelial growth factor agents has been improved since its introduction in Germany. Several observational studies have demonstrated an increased frequency of injections in parallel with improved visual outcomes during the first year of treatment over the last 7 years. These results are reflected in several case series. However, studies with a longer follow-up reported that visual function regressed to baseline vision following an initial improvement, e...

Background: Dyslipidemia, particularly high-density lipoprotein cholesterol (HDL-C), has recently been implicated in the pathogenesis of age-related macular degeneration (AMD), the leading cause of vision loss. However, epidemiological studies have yielded conflicting results. Methods: We investigated the causal role of plasma lipid levels in AMD in multiethnic populations comprising 16 144 advanced AMD cases and 17 832 controls of European descent, together with 2219 cases and 5275 controls of Asian descent, using Mendelian randomization in three models...

Amyloid-beta (Aβ) is a hallmark component of age-related macular degeneration (AMD), which induces secretion of pro-inflammatory cytokines from retinal pigment epithelium (RPE). Previous studies have shown that p50/RelA (p65), a member of NF-κB family, is an essential pro-inflammatory transcription factor responding to Aβ1-40 stimulation, but few focused on the other two Rel transcription factor members - RelB and c-Rel - and their role in Aβ1-40-mediated inflammation. It was reported that RelA, RelB and c-Rel are also implicated in various NF-κB-mediated inflammatory diseases...

PURPOSE: Understanding the apparent paradoxical role of zinc in the pathogenesis and prevention of age-related macular degeneration (AMD) has been limited by the lack of animal models for its detection in sub-retinal epithelial deposits (drusen), a definitive early hallmark of AMD. In-vitro studies using Zinpyr-1 showed drusen contained high levels of zinc, but the probe was not suitable for in-vivo studies. This study compares Zinpyr-1 to ZPP1, a new fluorescein-based probe for zinc, to assess the potential of ZPP1 for in-vivo detection of zinc in drusen...

Switching of anti-vascular endothelial growth factor (VEGF) therapy in the management of poorly responsive exudative age-related macular degeneration (AMD) has had suggested benefits in individual reports that have yet to be consolidated. In this retrospective review, 24 studies published between 2009 and 2014 were identified. Reasons for switching included tachyphylaxis, health insurance coverage, cost issues, and nonresponse or inadequate response. Nine studies had data that could be used for comparison between studies...

It is a great challenge to monitor the physical and chemical transformation of nanoparticles at environmentally relevant concentration levels, mainly because the commonly used techniques like dynamic light scattering and transmission electron microscope are unable to characterize and quantify trace level nanoparticles in complex matrices. Herein, we demonstrate the on-line coupled system of hollow fiber flow field-flow fractionation (HF5), mini-column concentration and inductively coupled plasma mass spectrometry (ICPMS) detection as an efficient approach to study the aggregation, and chemical transformation of silver nanoparticles (AgNPs) and ionic Ag species in the aqueous environment at ng/mL levels...

INTRODUCTION: The estimation of utility values for the economic evaluation of therapies for wet age-related macular degeneration (AMD) is a particular challenge. Previous economic models in wet AMD have been criticized for failing to capture the bilateral nature of wet AMD by modelling visual acuity (VA) and utility values associated with the better-seeing eye only. METHODS: Here we present a de novo regression analysis using generalized estimating equations (GEE) applied to a previous dataset of time trade-off (TTO)-derived utility values from a sample of the UK population that wore contact lenses to simulate visual deterioration in wet AMD...

Iron is implicated in age-related macular degeneration (AMD). The aim of this study was to see if long-term, experimental iron administration with aging modifies retinal and choroidal structures and expressions of iron handling proteins, to understand some aspects of iron homeostasis. Male Wistar rats were fed with ferrous sulphate heptahydrate (500mg/kg body weight/week, oral; elemental iron availability: 20%) from 2 months of age onward until they were 19.5 month-old. At 8, 14 and 20 months of age, they were sacrificed and serum and retinal iron levels were detected by HPLC...

Passive biochemical reactors (PBRs) are a viable alternative to neutralization plants for the treatment of acid mine drainage (AMD) because they require lower investment costs and use residual materials. However, high iron (Fe) concentrations (≥0.5 g/L) in AMD are challenging for their long-term efficiency. Sorption and precipitation are the main Fe removal mechanisms, but the relative importance of each is mostly unknown. In this study, locally available natural materials (organic and inorganic) were characterized and tested for their performance in Fe removal from highly contaminated AMD (pH 3...

Acid mine drainage (AMD) is extremely acidic, sulfate-rich effluent from abandoned or active mine sites that also contain elevated levels of heavy metals. Untreated AMD can contaminate surface and groundwater and pose severe ecological risk. Both active and passive methods have been developed for AMD treatment consisting of abiotic and biological techniques. Abiotic techniques are expensive and can create large amounts of secondary wastes. Passive biological treatment mainly consists of aerobic or anaerobic constructed wetlands...

The effect of hydraulic retention time (HRT) on the microbial community during acid mine drainage (AMD) treatment was investigated. Physicochemical and molecular (illumina and qPCR) analyses were performed on reactive mixtures collected from seven bioreactors in three-operation period (8, 17 and 36weeks). Long HRT (4day) favored the relative abundance of SRB, causing the increase of residual sulfides and short HRT (1day) affected the anaerobic conditions of the bioreactors and favored the presence the acidophilic chemolithotrophic microorganisms...
