Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104903
Abstract:
The online appointment system at the university health centre was intro-duced by the University of Technology (UTech), Jamaica management in 2014. The purpose of this study was to determine the users’ views of the online appointment system, as well as their views about the services offered at the university health centre. To achieve this purpose, a descriptive research design was used to answer three research questions. The con-venience sampling method was used to select 50 participants (30 students & 20 university staff members), who visited and used the health centre services. A questionnaire with an internal consistency of 0.87 was used to collect data from the participants who gave their consent. The findings showed that a majority of those who used the online appointment system were satisfied. The general view of the users about the health services provided at the health centre was positive. The results of the Fisher Exact test showed that there were differences in the views of the students and the staff in their responses to two items that measured the services provided by the doctors, and the access to the different services. Recommendations were made on how to improve the online appointment system as it relates to timing, and quality of services provided.
Non-Vitamin K Antagonist Oral Anticoagulants: Redefining the Role of the Nurse to Improve Patient Care  [PDF]

Abstract: Thromboembolic disorders and their associated long-term complications place a burden on patients, healthcare systems and society. Non-vitamin K antagonist (VKA) oral anticoagulants (OACs), including rivaroxaban, dabigatran, apixaban and edoxaban, are effective for the prevention of stroke in patients with non-valvular atrial fibrillation and for the treatment and secondary prevention of venous thromboembolism. The increasing uptake of the non-VKA OACs in primary care lessens the burden of care and allows for an easier transition of treatment from hospital to home. This transformation in terms of patient management has resulted in the need to empower nurses working in this field to endorse management strategies with a focus on patient education and long-term management (i.e. assessment of compliance, scheduling follow-up visits). Management of both venous thromboembolism and stroke prevention in patients with non-valvular atrial fibrillation requires a multidisciplinary team approach and, looking to the future, nurses are likely to have a key role at the heart of the thrombosis team. This review aims to provide nurses with the confidence to manage patients with thromboembolic disorders, and highlights the importance of responsible non-VKA OAC use and the impact that this can have on improving patient care and outcomes.
The Conceptual Integration Modeling Framework: Abstracting from the Multidimensional Model

Computer Science , 2010,
Abstract: Data warehouses are overwhelmingly built through a bottom-up process, which starts with the identification of sources, continues with the extraction and transformation of data from these sources, and then loads the data into a set of data marts according to desired multidimensional relational schemas. End user business intelligence tools are added on top of the materialized multidimensional schemas to drive decision making in an organization. Unfortunately, this bottom-up approach is costly both in terms of the skilled users needed and the sheer size of the warehouses. This paper proposes a top-down framework in which data warehousing is driven by a conceptual model. The framework offers both design time and run time environments. At design time, a business user first uses the conceptual modeling language as a multidimensional object model to specify what business information is needed; then she maps the conceptual model to a pre-existing logical multidimensional representation. At run time, a system will transform the user conceptual model together with the mappings into views over the logical multidimensional representation. We focus on how the user can conceptually abstract from an existing data warehouse, and on how this conceptual model can be mapped to the logical multidimensional representation. We also give an indication of what query language is used over the conceptual model. Finally, we argue that our framework is a step along the way to allowing automatic generation of the data warehouse.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0017424
Abstract: Escherichia coli O157:H7 strain 86–24 grown in MacConkey broth (MB) shows almost no adherence to cultured epithelial cells but adheres well in pig ligated intestines. This study investigated the mechanisms associated with the difference between in-vitro and in-vivo adherence of the MB culture.
FimH Adhesin of Type 1 Fimbriae Is a Potent Inducer of Innate Antimicrobial Responses Which Requires TLR4 and Type 1 Interferon Signalling

Abstract: Components of bacteria have been shown to induce innate antiviral immunity via Toll-like receptors (TLRs). We have recently shown that FimH, the adhesin portion of type 1 fimbria, can induce the innate immune system via TLR4. Here we report that FimH induces potent in vitro and in vivo innate antimicrobial responses. FimH induced an innate antiviral state in murine macrophage and primary MEFs which was correlated with IFN-β production. Moreover, FimH induced the innate antiviral responses in cells from wild type, but not from MyD88?/?, Trif?/?, IFN?α/βR?/? or IRF3?/? mice. Vaginal delivery of FimH, but not LPS, completely protected wild type, but not MyD88?/?, IFN-α/βR?/?, IRF3?/? or TLR4?/? mice from subsequent genital HSV-2 challenge. The FimH-induced innate antiviral immunity correlated with the production of IFN-β, but not IFN-α or IFN-γ. To examine whether FimH plays a role in innate immune induction in the context of a natural infection, the innate immune responses to wild type uropathogenic E. coli (UPEC) and a FimH null mutant were examined in the urinary tract of C57Bl/6 (B6) mice and TLR4-deficient mice. While UPEC expressing FimH induced a robust polymorphonuclear response in B6, but not TLR4?/? mice, mutant bacteria lacking FimH did not. In addition, the presence of TLR4 was essential for innate control of and protection against UPEC. Our results demonstrate that FimH is a potent inducer of innate antimicrobial responses and signals differently, from that of LPS, via TLR4 at mucosal surfaces. Our studies suggest that FimH can potentially be used as an innate microbicide against mucosal pathogens.

Abstract: Background: Increased consumption of foods containing plant sterols has the potential to reduce the incidence of coronary heart disease (CHD) and thus reduce costs associated with treating that disease in a significant way. This paper reports the results of an investigation of the potential monetary benefits of allowing foods enriched with plant sterols to be marketed in Canada. Objective: The objective of this research was to estimate the annual savings that would accrue to Canada's single-payer publicly funded health care system if plant sterols were approved for use. If foods containing plant sterols are consumed at a sufficient rate, a reduction in CHD should follow. Given the significant costs associated with CHD, approval of plant sterols in Canada has important public policy implications. Design: This research employs a variation of traditional cost-of-illness analysis entailing four steps: (1) estimation of a ‘success rate’ (proportion of persons who would consume plant sterols at the necessary rate); (2) presumption of blood cholesterol reduction due to plant sterol consumption; (3) assumption of reduction in CHD that follows from blood cholesterol reduction; and (4) calculation of cost savings associated with reduced incidence of CHD. Results: Calculations were carried out for four scenarios: ideal, optimistic, pessimistic, and very pessimistic. It was estimated that between $38 million (very pessimistic scenario) and $2.45 billion (ideal scenario) could be saved annually by Canada's health care system with plant sterol-enriched food products being made available for sale. Conclusion: Significant expenditure reductions within Canada's publicly funded health care system could be realized with plant sterols approved for sale. Reduced CHD resulting from lower blood cholesterol levels would lessen the financial burden of disease in Canada.

Exclus?o e educa??o social: conceitos em superfície e fundo
Ribeiro, Marlene;
Educa??o & Sociedade , 2006, DOI: 10.1590/S0101-73302006000100008
Abstract: this paper approaches the relationship between exclusion and social education. it aims at bringing out elements that lead to discuss reality and conceptions of social exclusion/inclusion and social education to dis-close the ideologies and interests that inform them. it develops the hypothesis that some kind of dispute between contradictory social and educational projects have resulted in strategies to fight exclusion and promote inclusion that are based on social education practices, as a response to the public social policies claimed by children and young people at risk. problemizing these concepts - exclusion and social education - may bring some contributions to the formulation of public education policies.
Exclus?o: problematizando o conceito
Ribeiro, Marlene;
Educa??o e Pesquisa , 1999, DOI: 10.1590/S1517-97021999000100004
Abstract: this work results from questions raised by the research project "pedagogy of hope in popular social movements: perspectives for work, politics and education envisaged by ?movimento dos sem terra? - mst (movement of landless people)"carried out by the federal university of rio grande do sul. in this paper the use of the category ?exclusion? is problematized with the purpose of assessing its potential to identify the ability of the popular social movements to break with processes of social exclusion and to find alternatives for work, social relationships and education. two possible uses of this category are the one made by marx when retracing the genesis of the capital versus work relationship, and the exposure of poverty and intolerance as the ingredients of the "new social issue". the ?culturalist bias?, the affiliation to the sociology of durkheim and the conceptual vagueness, however, set limits to the category which thereby can not reach an understanding of poverty and unemployment as produced by the class struggle. therefore, it can not apprehend popular social movements as producers of collective alternatives for work, society and education.
Educa??o para a cidadania: quest?o colocada pelos movimentos sociais
Ribeiro, Marlene;
Educa??o e Pesquisa , 2002, DOI: 10.1590/S1517-97022002000200009
Abstract: the article problematizes the relationship between citizenship and the education of the popular classes. it has as its goal to establish a dialogue in space and in time with the concept of citizenship, attempting to verify if the latter concept has contents to contribute to the education of the popular classes, and what are its limits and possibilities that must be made clear in order to give visibility and room to new concepts and practices. to fulfill this goal the concepts of citizenship and education are immersed in history and philosophy or, more specifically, in the conditions for the constitution of a citizen, whose analysis results in the education necessary for such constitution. the contradictions exhibit the possibilities and limits of education as the main road to citizenship, as well as the fact that popular social movements create new forms of producing, living together, and educating themselves. in this process, social movements gestate new concepts whose contents, characterized by practices of cooperation and solidarity, seem to envisage social emancipation in a sense broader than that proposed by the formal principles of freedom and equality upon which the bourgeois citizenship rests. thus, popular social movements also broaden the horizon of education beyond citizenship.
