The established histopathologic attributes of FFD are nonspecific, and a retention vesicle is difficult to find even in level sections. In contrast, perifollicular foam cells are a distinct, relatively consistent, and specific feature of FFD. We contend that perifollicular foam cells represent a useful hallmark of FFD.
Extrapolation using national hospital admission data and the prevalence identified by pooling international studies should be carried out with great caution.
The costs of potentially preventable hospital admissions related to medication are considerable. Therefore, patient safety interventions to prevent ADEs and hospital admissions may be cost-effective or even cost saving.
A multicomponent pharmaceutical care intervention does not prevent medication-related hospital admissions. Whether this is true for such interventions in general is unknown, because the PHARM study was underpowered. The intervention may significantly reduce medication-related hospitalizations in patients with five or more comorbidities, but this is only based on a post hoc analysis and thus needs confirmation in large controlled trials.
Filamentous fungi are important producers of plant polysaccharide degrading enzymes that are used in many industrial applications. These enzymes are produced by the fungus to liberate monomeric sugars that are used as carbon source. Two of the main components of plant polysaccharides are l-arabinose and d-xylose, which are metabolized through the pentose catabolic pathway (PCP) in these fungi. In Aspergillus niger, the regulation of pentose release from polysaccharides and the PCP involves the transcriptional activators AraR and XlnR, which are also present in other Aspergilli such as Aspergillus nidulans. The comparative analysis revealed that the regulation of the PCP by AraR differs in A. nidulans and A. niger, whereas the regulation of the PCP by XlnR was similar in both species. This was demonstrated by the growth differences on l-arabinose between disruptant strains for araR and xlnR in A. nidulans and A. niger. In addition, the expression profiles of genes encoding l-arabinose reductase (larA), l-arabitol dehydrogenase (ladA) and xylitol dehydrogenase (xdhA) differed in these strains. This data suggests evolutionary changes in these two species that affect pentose utilisation. This study also implies that manipulating regulatory systems to improve the production of polysaccharide degrading enzymes, may give different results in different industrial fungi.Electronic supplementary materialThe online version of this article (doi:10.1007/s00253-011-3242-2) contains supplementary material, which is available to authorized users.
To evaluate the effect of non-dispensing pharmacists (NDPs) integrated in general practice on medication-related hospitalisations, drug burden index and costs in patients at high risk of medication problems (being 65 years or older and using 5 or more chronic medications). Methods: This was a multicentre, nonrandomised, controlled intervention study with pre-post comparison (2013 vs June 2014 to May 2015) in 25 general practices in the Netherlands, comparing NDP-led care (intervention) with 2 current pharmaceutical care models (usual care and usual care plus). In the intervention group, 10 specially trained NDPs were employed in general practices to take integral responsibility for the pharmaceutical care. They provided a broad range of medication therapy management services both on patient level (e.g. clinical medication review) and practice level (e.g. quality improvement projects). In the control groups, pharmaceutical care was provided as usual by general practitioners and community pharmacists, or as usual plus, when pharmacists were additionally trained in performing medication reviews. Results: Overall, 822 medication-related hospitalisations were identified among 11 281 high-risk patients during the intervention period. After adjustment for clustering and potential confounders, the rate ratio of medication-related hospitalisations in the intervention group compared to usual care was 0.68 (95% confidence interval: 0.57-0.82) and 1.05 (95% confidence interval: 0.73-1.52) compared to usual care plus. No differences in drug burden index or costs were found. Conclusions: In general practices with an integrated NDP, the rate of medicationrelated hospitalisations is lower compared to usual care. No differences with usual care plus were found.
Inappropriate prescribing is a major health care issue, especially regarding older patients on polypharmacy. Multiple implicit and explicit prescribing tools have been developed to improve prescribing, but these have hardly ever been used in combination. The Systematic Tool to Reduce Inappropriate Prescribing (STRIP) combines implicit prescribing tools with the explicit Screening Tool to Alert physicians to the Right Treatment and Screening Tool of Older People's potentially inappropriate Prescriptions criteria and has shared decision-making with the patient as a critical step. This article describes the STRIP and its ability to identify potentially inappropriate prescribing. The STRIP improved general practitioners' and final-year medical students' medication review skills. The Web-application STRIP Assistant was developed to enable health care providers to use the STRIP in daily practice and will be incorporated in clinical decision support systems. It is currently being used in the European Optimizing thERapy to prevent Avoidable hospital admissions in the Multimorbid elderly (OPERAM) project, a multicentre randomized controlled trial involving patients aged 75 years and older using multiple medications for multiple medical conditions. In conclusion, the STRIP helps health care providers to systematically identify potentially inappropriate prescriptions and medication-related problems and to change the patient's medication regimen in accordance with the patient's needs and wishes. This article describes the STRIP and the available evidence so far. The OPERAM study is investigating the effect of STRIP use on clinical and economic outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
