Specialized multi-disciplinary heart failure clinics in Ontario, Canada: an environmental scan
Wijeysundera Harindra C,Trubiani Gina,Abrahamyan Lusine,Mitsakakis Nicholas
BMC Health Services Research , 2012, DOI: 10.1186/1472-6963-12-236
Abstract: Background Multi-disciplinary heart failure (HF) clinics have been shown to improve outcomes for HF patients in randomized clinical trials. However, it is unclear how widely available specialized HF clinics are in Ontario. Also, the service models of current clinics have not been described. It is therefore uncertain whether the efficacy of HF clinics in trials is generalizable to the HF clinics currently operating in the province. Methods As part of a comprehensive evaluation of HF clinics in Ontario, we performed an environmental scan to identify all HF clinics operating in 2010. A semi-structured interview was conducted to understand the scope of practice. The intensity and complexity of care offered were quantified through the use of a validated instrument, and clinics were categorized as high, medium or low intensity clinics. Results We identified 34 clinics with 143 HF physicians. We found substantial regional disparity in access to care across the province. The majority of HF physicians were cardiologists (81%), with 81% of the clinics physically based in hospitals, of which 26% were academic centers. There was a substantial range in the complexity of services offered, most notably in the intensity of education and medication management services offered. All the clinics focused on ambulatory care, with only one having an in-patient focus. None of the HF clinics had a home-based component to care. Conclusions Multiple HF clinics are currently operating in Ontario with a wide spectrum of care models. Further work is necessary to understand which components lead to improved patient outcomes.
A model-driven approach to broaden the detection of software performance antipatterns at runtime
Antinisca Di Marco,Catia Trubiani
Computer Science , 2014, DOI: 10.4204/EPTCS.147.6
Abstract: Performance antipatterns document bad design patterns that have negative influence on system performance. In our previous work we formalized such antipatterns as logical predicates that predicate on four views: (i) the static view that captures the software elements (e.g. classes, components) and the static relationships among them; (ii) the dynamic view that represents the interaction (e.g. messages) that occurs between the software entities elements to provide the system functionalities; (iii) the deployment view that describes the hardware elements (e.g. processing nodes) and the mapping of the software entities onto the hardware platform; (iv) the performance view that collects specific performance indices. In this paper we present a lightweight infrastructure that is able to detect performance antipatterns at runtime through monitoring. The proposed approach precalculates such predicates and identifies antipatterns whose static, dynamic and deployment sub-predicates are validated by the current system configuration and brings at runtime the verification of performance sub-predicates. The proposed infrastructure leverages model-driven techniques to generate probes for monitoring the performance sub-predicates and detecting antipatterns at runtime.
Psychological Distress in California: Identifying Those at Greatest Risk  [PDF]
Gina Marie Piane
Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.48075
Abstract:

In order to address the unmet need for prevention and treatment of psychological distress and mental disorders, program planners and treatment providers need to identify individuals at high risk. The results of the California Health Interview Survey from 2009 (n = 47,614) indicate that there are high relative risks by demographics and smoking status for reports of psychological distress and intermediate measures: feeling nervous, hopeless, worthless, depressed, restless, and that everything is an effort. Specific demographic factors and smoking status can predict a greater need for prevention and treatment of psychological distress and lack of insurance coverage for treatment. Profiles associated with high risk can help in referral for diagnosis or to plan prevention programs.

Maternal Mortality Correlates by Nation  [PDF]

Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.410085
Abstract: Background: This study reports the results of a secondary analysis of data provided by the World Health Organization to determine the correlates of maternal mortality among all reporting nations worldwide. Historically, maternal mortality ratios have declined in nations that provided a system for access to skilled care for the majority of its women. Currently, maternal mortality ratios are associated with access to skilled care as well as economic indicators, literacy, education, access to contraceptives, transportation and HIV prevalence. Methods: Descriptive statistics, bi-variate correlations and multiple linear regression analyses are reported using maternal mortality ratios as the dependent variable. In addition, an examination of countries that are exceptions to the regression is also reported. Results: Strong positive Pearson two-tailed correlations were found between MMR and infant mortality rate (0.866), total fertility rate (0.854), poverty rate (0.756), and adolescent fertility rate (0.710). Strong negative correlations were found between MMR and percentage of births attended by a skilled attendant (-0.786), percentage of women using contraceptives (-0.786), and adult literacy rate (-0.710). Eighty-one percent of the variation in MMR can be explained by differences in IMR, percent of births attended by a skilled provider, percent of women using contraceptive, total fertility rate, adolescent fertility rate, adult literacy rate and poverty. Discussion: Examination of the correlates of maternal mortality gives direction to the effort to achieve the WHO’s Millennium Development Goal of reducing maternal mortality by two-thirds from 1995-2015.
Determinants of Life Insurance Policy Surrenders  [PDF]
Thomas Poufinas, Gina Michaelide
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.98089
Abstract: Life insurance policies assist individuals maintain the value of their money and build savings to be used in the future. However in times of crisis their attitude may change. On one hand, they have an interest in keeping their policies, as they can be used to cover their future, medium-term or long-term needs in case of retirement or death. On the other hand, they may need the premium money or the accumulated savings to meet short-term needs so they lapse or surrender them—when a surrender value exists. A natural question is what are the drivers of the behavior of the insured? When do they decide to stop them and when do they choose to maintain them? We use linear regression to identify how certain main macroeconomic variables (Gross Domestic Product (GDP) per capita growth, unemployment, inflation, short-term and long term interest rates, and consumer confidence index) can explain the behavior of the insured towards keeping or interrupting their life insurance policy. We do that for pension savings (pure and plain vanilla endowment—including pensions), term life, whole life and unit linked individual policies.
Functional assay, expression of growth factors and proteins modulating bone-arrangement in human osteoblasts seeded on an anorganic bovine bone biomaterial

Abstract: The basic aspects of bone tissue engineering include chemical composition and geometry of the scaffold design, because it is very important to improve not only cell attachment and growth but especially osteodifferentiation, bone tissue formation, and vascularization. Geistlich Bio-Oss (GBO) is a xenograft consisting of deproteinized, sterilized bovine bone, chemically and physically identical to the mineral phase of human bone.In this study, we investigated the growth behaviour and the ability to form focal adhesions on the substrate, using vinculin, a cytoskeletal protein, as a marker. Moreover, the expression of bone specific proteins and growth factors such as type I collagen, osteopontin, bone sialoprotein, bone morphogenetic protein-2 (BMP-2), BMP-7 and de novo synthesis of osteocalcin in normal human osteoblasts (NHOst) seeded on xenogenic GBO were evaluated. Our observations suggest that after four weeks of culture in differentiation medium, the NHOst showed a high affinity for the three dimensional biomaterial; in fact, cellular proliferation, migration and colonization were clearly evident. The osteogenic differentiation process, as demonstrated by morphological, histochemical, energy dispersive X-ray microanalysis and biochemical analysis was mostly obvious in the NHOst grown on three-dimensional inorganic bovine bone biomaterial. Functional studies displayed a clear and significant response to calcitonin when the cells were differentiated. In addition, the presence of the biomaterial improved the response, suggesting that it could drive the differentiation of these cells towards a more differentiated osteogenic phenotype. These results encourage us to consider GBO an adequate biocompatible three-dimensional biomaterial, indicating its potential use for the development of tissue-engineering techniques.

Abstract: Broadcasting a killer: The Virginia Tech shooting and the effects of mass communication. When the rampant killer responsible for the shootings at the Virginia Tech campus in Blacksburg, Virginia, Cho Seung-Hui, sent a package containing about 1800 words of text, several Quicktime home videos and 43 photos to the news-network giant NBC on the day of the shooting, 16 April 2007, a debate was immediately sparked in the global media about whether it should have been aired or not. NBC coined the term “multimedia manifesto” to describe Cho’s riveting and macabre ranting on film, which was immediately shown to millions around the globe. The network aired the footage, promting TIME magazine to muse that the “technology for recording horror has advanced, even if the technology for inflicting it has not...Cho’s final testament was like a deranged MySpace parody” (Poniewozik, 2007). The package shows Cho brandishing hammers? and guns in defiant poses and the text reveals much about the young killer’s state of mind. NBC president
