  4. Context-aware quality of life telemonitoring for a novel healthcare paradigm

    Miralles Barrachina, Felip
    Our healthcare systems are facing sustainability challenges caused by a demographic shift with ageing, chronicity and disability growing in our society. A novel healthcare paradigm should be founded on 4P medicine: Preventive, Predictive, Personalized, and Participatory medicine needs new methodologies and tools enabled by Information and Communication Technologies (ICTs). One of the key technology enablers for 4P medicine is telemonitoring, i.e. ICTs to monitor the health status of a patient from a distance, which may trigger 4P decision making. A new generation of telemonitoring tools allow prescription and follow-up around the main chronic care strategies, namely, therapeutic adherence and healthy...

    Data envelopment analysis (DEA) is a method of operations research that has not yet been applied in the field of obesity research. However, DEA might be used to evaluate individuals' susceptibility to obesity, which could help establish effective risk models for the onset of obesity. Therefore, we conducted this study to evaluate the feasibility of applying DEA to predict obesity, by calculating efficiency scores and evaluating the usefulness of risk models. In this study, we evaluated data from the Takahata study, which was a population-based cohort study (with a follow-up study) of Japanese people who are >40 years old. For...

  14. Efficiency in Health Care Sector in Tamil Nadu (India): An Exploratory Analysis

    Purohit BC
    Keeping in view the importance of efficiency in resource utilization in healthcare sector, we focus on efficiency of health care system at sub-state level (i.e., district level) in India using Tamil Nadu state and its district level data for 2012-13. It being an economically advanced state, in terms of Infant Mortality Rate (IMR) the state ranks second lowest among the Indian states. We explore the reasons for relative performance of different districts with Data Envelopment Analysis. We used IMR as output variables. Using Principal component analysis we tried a sub-set of variables which had low correlations. Thus three components with...

  15. Biosecurity on cattle farms: a study in north-west England.

    Marnie L Brennan; Robert M Christley
    BACKGROUND: Few studies have considered in detail the range of biosecurity practices undertaken on cattle farms, particularly within the UK. In this study, 56 cattle farmers in a 100 km² area of north-west England were questioned regarding their on-farm biosecurity practices, including those relating to animal movements, equipment sharing and companies and contractors visiting the farms. METHODOLOGY/PRINCIPAL FINDINGS: There was great variation between farms in terms of the type of, and extent to which, biosecurity was carried out. For example, the majority of farmers did not isolate stock bought onto the farm, but a small proportion always isolated stock. Many...

    Juan E Corral; Lauren D Arnold; Erwin E Argueta; Akshay Ganju; Joaquín Barnoya
    BACKGROUND: Guatemala is currently undergoing an epidemiologic transition. Preventive services are key to reducing the burden of non-communicable diseases, and smoking counseling and cessation are among the most cost-effective and wide-reaching strategies. Internal medicine physicians are fundamental to providing such services, and their knowledge is a cornerstone of non-communicable disease control. METHODS: A national cross-sectional survey was conducted in 2011 to evaluate knowledge of clinical preventive services for non-communicable diseases. Interns, residents, and attending physicians of the internal medicine departments of all teaching hospitals in Guatemala completed a self-administered questionnaire.

  17. Birth weight and long-term overweight risk: systematic review and a meta-analysis including 643,902 persons from 66 studies and 26 countries globally.

    Karen Schellong; Sandra Schulz; Thomas Harder; Andreas Plagemann
    BACKGROUND: Overweight is among the major challenging health risk factors. It has been claimed that birth weight, being a critical indicator of prenatal developmental conditions, is related to long-term overweight risk. In order to check this important assumption of developmental and preventive medicine, we performed a systematic review and comprehensive meta-analysis. METHODS AND FINDINGS: Relevant studies published up to January 2011 that investigated the relation between birth weight and later risk of overweight were identified through literature searches using MEDLINE and EMBASE. For meta-analysis, 66 studies from 26 countries and five continents were identified to be eligible, including 643,902 persons...

  18. The identification of pathway markers in intracranial aneurysm using genome-wide association data from two different populations.

    Burcu Bakir-Gungor; Osman Ugur Sezerman
    The identification of significant individual factors causing complex diseases is challenging in genome-wide association studies (GWAS) since each factor has only a modest effect on the disease development mechanism. In this study, we hypothesize that the biological pathways that are targeted by these individual factors show higher conservation within and across populations. To test this hypothesis, we searched for the disease related pathways on two intracranial aneurysm GWAS in European and Japanese case-control cohorts. Even though there were a few significantly conserved SNPs within and between populations, seven of the top ten affected pathways were found significant in both populations....

  19. Insulin resistance, the metabolic syndrome and polycystic ovary syndrome

    Conway, G
    © 2010 The Royal College of Obstetricians and Gynaecologists.Introduction The first reports of a link between insulin and polycystic ovary syndrome (PCOS) appeared in the 1980s. First there was the demonstration of a link between hyperinsulinism and hyperandrogenism and then, soon after, the demonstration that non-obese women with PCOS were insulin resistant. These two seminal papers opened up a whole new field of investigation exploring the relationship between what was later to be called the metabolic syndrome and PCOS. Much of the initial work in this area focused on the correlation between insulin and androgens in the circulation, with a...

  20. Perspectiva del manejo homeopático de las enfermedades tropicales

    Moreno Rey, Angela Milena
    Se calcula que cerca de 2700 millones de personas en el mundo viven en condiciones de pobreza y más de 1000 millones de personas se encuentran afectadas por una o varias enfermedades tropicales desatendidas. Las poblaciones más vulnerables son aquellas que viven en condiciones socioeconómicas de pobreza, las comunidades indígenas y los afrodescendientes. La OMS ha encaminado estrategias de integración en salud, que abarquen la problemática global de estas comunidades y en un marco de inclusión resalta los aportes que las Medicinas Tradicionales y Complementarias pueden proporcionar en la atención primaria de las enfermedades.
