BACKGROUND The four components that make up the current dual-mobility artificial hip j.int design are the femoral head,the inner liner,the outer liner as a metal cover to prevent wear,and the acetabular *** acetabular cup and the outer liner were constructed of 316L stainless *** the same time,the inner liner was made of ultra-high-molecular-weight polyethylene(UHMWPE).As this new dual-mobility artificial hip j.int has not been researched extensively,more tribological research is needed to predict *** thickness of the inner liner is a significant component to consider when calculating the contact *** To make use of finite element analysis to gain a better understanding of the contact behavior in various inner liner thicknesses on a new model of a dual-mobility artificial hip j.int,with the ultimate obj.ctive of determining the inner liner thickness that was most suitable for this particular type of dual-mobility artificial hip *** In this study,the size of the femoral head was compared between two diameters(28 mm and 36 mm)and eight inner liner thicknesses ranging from 5 mm to 12 *** the finite element method,the contact parameters,including the maximum contact pressure and contact area,have been evaluated in light of the Hertzian contact *** simulation was performed statically with dissipated energy and asymmetric *** types of interaction were surface-to-surface contact and normal contact *** The maximum contact pressures in the inner liner(UHMWPE)at a head diameter of 28 mm and 36 mm are between 3.7-13.5 MPa and 2.7-10.4 MPa,*** maximum von Mises of the inner liner,outer liner,and acetabular cup are 2.4–11.4 MPa,15.7–44.3 MPa,and 3.7–12.6 MPa,respectively,for 28 mm *** the maximum von Mises stresses of the 36 mm head are 1.9-8.9 MPa for the inner liner,9.9-32.8 MPa for the outer liner,and 2.6-9.9 MPa for the acetabular cup.A head with a diameter of 28 mm should have an inner line

Using Geographic Information Systems (GIS) for Targeted National Recruitment of Community-Dwelling Caregivers Managing Dementia-Related Behavioral and Psychological Symptoms: A Recruitment Approach for a Randomized Clinical Trial

引用

j.urnal of Geographic Information System 2021年第3期13卷 302-317页

作者： danny L. Scerpella Nicole G. Bouranis Melinda j. Webster Maria Dellapina Sokha Koeuth Lauren j. Parker Helen C. Kales Laura N. Gitlin School of Public Health Johns Hopkins University Baltimore USA College of Nursing and Health Professions Drexel University Philadelphia USA Department of Psychiatry University of California-Davis Sacramento USA

Over 16 million caregivers of people living with dementia require support in a range of issues, including self-care, disease education, and guidance for how to manage behavioral and psychological symptoms of dementia (BPSD). Non-pharmacological interventions are needed to address these areas, and online applications have been shown to be safe and effective. To ensure the efficacy of such interventions, racially, ethnically, geographically, and socioeconomically diverse participants must be recruited to increase the generalizability of study outcomes. This protocol paper describes a recruitment plan using Geographic Information Systems (GIS) to reach a representative sample of caregivers across the United States for a national Phase III clinical study. Using publicly available census data from the American Community Survey (ACS), combined with location data for local aging resources such as Area Agencies on Aging (AAA), recruitment will be derived from data analysis conducted in ESRI ArcGIS v10.7.1. Datasets including age, gender, income, and education will be assessed nationally at the county and census tract spatial scale in a nine-step process to develop recruitment priority areas containing high concentrations of eligible participants living in the community. Overall, the current protocol will demonstrate the value of GIS in tailoring targeted outreach strategies to recruit community-dwelling populations through local resource institutions. This novel approach may have far-reaching implications in future recruitment initiatives and help to secure racially/ethnically diverse samples.

Difficulties in Recruitment for a Randomised Controlled Trial of Lifestyle Intervention for Type 2 Diabetes: Implications for Diabetes Management

Open j.urnal of Endocrine and Metabolic Diseases 2012年第4期2卷 53-57页

Weiland Department of General Practice Faculty of Medicine Nursing and Health Sciences Monash University Clayton Australia Department of Medicine Faculty of Medicine and Health Sciences The University of Melbourne Royal Melbourne Hospital Melbourne Australia East Bentleigh General Practice Melbourne Australia Emergency Practice Innovation Centre St Vincent’s Hospital Melbourne Australia Formerly Department of Endocrinology St Vincent’s Hospital Melbourne Australia Manningham General Practice Melbourne Australia The Butterfly Foundation Malvern Australia The Gawler Foundation Yarra Junction Australia

Obj.ctive: To report our experience of attempting a randomised controlled trial of an intensive lifestyle intervention for early type 2 diabetes delivered in a residential setting. Methods: We established a trial requiring 84 participants (46 standard care and 38 intervention) to detect a 1% difference in HbA1c between intervention and control groups at 12 months, allowing for attrition. Ethics approval was obtained from Monash University. Results: The study was abandoned after five months of consistent promotion due to recruitment failure (four subj.cts recruited). Conclusion: It appears to be difficult for patients with diabetes to commit to a live-in period of education regarding lifestyle modification as a means of treating the illness. We recommend better education of patients and their doctors about the potential health benefits of lifestyle change to manage type 2 diabetes, and further research into novel methods of delivering lifestyle advice which are both effective and sustainable.

LINKING SEDIMENT EXPOSURE WITH EFFECTS: MODELING TECHNIQUES, ORGANIC AVAILABILITY AND UPTAKE

引用

International j.urnal of Sediment Research 2003年第2期 208-213页

作者： Xiaoxia LU ,danny REIBLE Hazardous Substance Research Center/S&SW Louisiana State University Baton Rouge LA 70803

The release or degradation of organic contaminants in soils and sediments often shows a period of relatively rapid change followed by a period of slow or no change due to limited desorption rates or extent. This desorption-resistance has been attributed to sequestration of the contaminants in the soil or sediment matrix. Studies have suggested that this sequestration may be associated with the nature of the sorbing media or due to conformational or other changes of the contaminants in the media. Regardless of the cause, however, desorption-resistance may influence the extent or rate of uptake of contaminants into receptor organisms. Deposit-feeding benthic worms represent an intense sediment-processing environment that can contribute significantly to the transport of contaminants from sediments to the overlying water and the food chain. This paper will focus on the availability of the desorption-resistant organic contaminants to benthic worms. The research to-date suggested that desorption-resistance might reduce but not eliminate contaminant uptake and accumulation, and the decrease in the availability was proportional to the reduction in the pore water concentration for a given compound. A model using the sediment-water partition coefficient to predict uptake was applied to describe the accumulation data for several organic contaminants. The results of this study suggested that a less conservative sediment quality criterion might be established in risk assessment and sediment remediation
