Decision-Making Competence in Older Adults: A Rosy View From a Longitudinal Investigation

Cross-sectional studies have suggested age-related differences in decision-making competence, but these differences may also reflect cohort-related effects. We present a longitudinal study of age-related changes over 5 years in older adults (aged 60-85) for 3 important aspects of decision-making competence: resistance to framing, applying decision rules, and resistance to sunk costs. The findings show small age-related longitudinal declines in resistance to framing but no decline in applying decision rules or resistance to sunk costs. The results also indicate that individuals' decision-making competence after 5 years is significantly related to their initial decision-making competence assessment and that the contribution of crystallized abilities to decision making in older adults is greater than previously thought

Painful Tooth Stimulation Elevates Matrix Metalloproteinase-8 Levels Locally in Human Gingival Crevicular Fluid

Recent studies have demonstrated that pulpal pain can induce neurogenic inflammatory reactions in gingiva and the expression of pro-inflammatory neuropeptides in gingival crevicular fluid (GCF). Neuropeptides co-ordinate the activity of immuno-effector cells and may influence the secretion of matrix metalloproteinase (MMP)-8, the major tissue-destructive protease in GCF. With this background, we studied whether experimental pulpal pain can trigger changes in GCF MMP-8 levels. The molecular forms of MMP-8 in the GCF of stimulated and non-stimulated teeth were analyzed by Western immunoblot, and MMP-8 levels by quantitative immunofluorometric assay. Painful stimulation of the upper incisor provoked significant elevations in GCF MMP-8 levels of the stimulated tooth. Western immunoblot revealed elevations in both neutrophil- and mesenchymal-type MMP-8 isoforms. At the same time, the GCF MMP-8 levels of the non-stimulated teeth were not changed. Analysis of these data indicated that pulpal pain can induce local elevations in MMP-8 levels in GCF

Community Pharmacists' Contribution to Medication Reviews for Older Adults : A Systematic Review

ObjectivesTo identify medication review interventions for older adults that involve community pharmacists and evidence of outcomes of these interventions. DesignSystematic review. MeasurementsCinahl, MEDLINE (Ovid), Scopus, International Pharmaceutical Abstracts, and Cochrane Library were searched for articles published between January 2000 and February 2016. Articles involving community pharmacists in medication reviews for outpatients aged 65 and older were included. Evidence of economic, clinical, and humanistic outcomes of interventions was summarized. ResultsSixteen articles were found that described 12 medication review interventions, of which 6 were compliance and concordance reviews, 4 were clinical medication reviews, and 2 were prescription reviews according to a previously developed typology. Community pharmacists' contributions to reviewing medications varied from sending the dispensing history to other healthcare providers to comprehensive involvement in medication management. The most commonly assessed outcomes of the interventions were medication changes leading to reduction in actual or potential drug-related problems (n=12) and improved adherence (n=5). ConclusionRegardless of community pharmacists' contributions to interventions, medication review interventions seem to reduce drug-related problems and increase medication adherence. More well-designed, rigorous studies with more sensitive and specific outcomes measures need to be conducted to assess the effect of community pharmacists' contributions to reviewing medications and improving the health of older adults.Peer reviewe

Enzymatic removal of cellulose from cotton/polyester fabric blends

The production of light-weight polyester fabrics from a polyester/cotton blended fabric, by means of the enzymatic removal of the cellulosic part of the material, was investigated. The removal of cotton from the blended fabric yielded more than 80% of insoluble microfibrillar material by the combined action of high beating effects and cellulase hydrolysis.Other major features of this enzymatic process for converting cotton fibers into microfibrillar material are bath ratio, enzyme dosage and treatment time

Gingival crevicular fluid MMP-8-concentrations in patients after acute myocardial infarction

<p>Abstract</p> <p>Background</p> <p>The aim of this study was to determine the presence of matrix metalloproteinase-8 in the gingival crevicular fluid (GCF) of patients after acute myocardial infarction (AMI).</p> <p>Methods</p> <p>A total of 48 GCF samples from 20 AMI patients, hospitalized at the Department of Cardiology and Angiology of the Johannes Gutenberg University Mainz, were investigated. Besides the myocardial infarction all patients suffered from chronic periodontal disease. Fifty-one GCF samples from 20 healthy age matched individuals with similar periodontal conditions served as controls. The dental examination included the assessment of oral hygiene, gingival inflammation, probing pocket depth, clinical attachment level and X-ray examination. The study was only carried out after the positive consent of the regional ethic commission. A quantitative assessment of aMMP-8 levels in the gingival crevicular fluid was performed with the help of the DentoAnalyzer (Dentognostics GmbH, Jena, Germany), utilising an immunological procedure.</p> <p>Results</p> <p>The aMMP-8 concentrations found in the gingival crevicular fluid of the AMI patients significantly differed (p = 0.001; mean value 30.33 ± 41.99 ng/ml aMMP-8) from the control group (mean value 10.0 ± 10.7 ng/ml aMMP-8). These findings suggest that periodontal inflammation in AMI patients might be associated with higher MMP-8-values compared to the healthy controls.</p> <p>Conclusions</p> <p>The acute myocardial infarction seems to influence the degree of periodontal inflammation, thus the measurement of the gingival crevicular fluid MMP8 levels seems to be a helpful biochemical test to obtain information about the severity of the periodontal disease.</p

"Older Adults with ASD: The Consequences of Aging." Insights from a series of special interest group meetings held at the International Society for Autism Research 2016-2017

A special interest group (SIG) entitled "Older Adults with ASD: The Consequences of Aging" was held at the International Society for Autism Research (INSAR) annual meetings in 2016 and 2017. The SIG and subsequent meetings brought together, for the first time, international delegates who were members of the autistic community, researchers, practitioners and service providers. Based on aging autism research that is already underway in UK, Europe, Australia and North America, discussions focussed on conceptualising the parameters of aging when referring to autism, and the measures that are appropriate to use with older adults when considering diagnostic assessment, cognitive factors and quality of life in older age. Thus, the aim of this SIG was to progress the research agenda on current and future directions for autism research in the context of aging. A global issue on how to define 'aging' when referring to ASD was at the forefront of discussions. The ‘aging’ concept can in principle refer to all developmental transitions. However, in this paper we focus on the cognitive and physical changes that take place from mid-life onwards. Accordingly, it was agreed that aging and ASD research should focus on adults over the age of 50 years, given the high rates of co-occurring physical and mental health concerns and increased risk of premature death in some individuals. Moreover, very little is known about the cognitive change, care needs and outcomes of autistic adults beyond this age. Discussions on the topics of diagnostic and cognitive assessments, and of quality of life and well-being were explored through shared knowledge about which measures are currently being used and which background questions should be asked to obtain comprehensive and informative developmental and medical histories. Accordingly, a survey was completed by SIG delegates who were representatives of international research groups across four continents, and who are currently conducting studies with older autistic adults. Considerable overlap was identified across different research groups in measures of both autism and quality of life, which pointed to combining data and shared learnings as the logical next step. Regarding the background questions that were asked, the different research groups covered similar topics but the groups differed in the way these questions were formulated when working with autistic adults across a range of cognitive abilities. It became clear that continued input from individuals on the autism spectrum is important to ensure that questionnaires used in ongoing and future are accessible and understandable for people across the whole autistic spectrum, including those with limited verbal abilities
