  2. Bayesian joint modeling of longitudinal and spatial survival AIDS data

    Martins, Rui; Silva, Giovani L.; Andreozzi, Valeska
    "Joint analysis of longitudinal and survival data has received increasing attention in the recent years, especially for analyzing cancer and AIDS data. As both repeated measurements (longitudinal) and time-to-event (survival) outcomes are observed in an individual, a joint modeling is more appropriate because it takes into account the dependence between the two types of responses, which are often analyzed separately. We propose a Bayesian hierarchical model for jointly modeling longitudinal and survival data considering functional time and spatial frailty effects, respectively. That is, the proposed model deals with nonlinear longitudinal effects and spatial survival effects accounting for the unobserved heterogeneity among individuals living in the same region. This joint...

  3. Joint dispersion model with a flexible link

    Martins, Rui
    "The objective is to model longitudinal and survival data jointly taking into account the dependence between the two responses in a real HIV/AIDS dataset using a shared parameter approach inside a Bayesian framework. We propose a linear mixed effects dispersion model to adjust the CD4 longitudinal biomarker data with a between-individual heterogeneity in the mean and variance. In doing so we are relaxing the usual assumption of a common variance for the longitudinal residuals. A hazard regression model is considered in addition to model the time since HIV/AIDS diagnostic until failure, being the coefficients, accounting for the linking between the longitudinal and survival processes, time-varying. This flexibility is...

  4. A gestão da performance nas culturas juvenis = Performance management in youth cultures

    Pegado, Elsa
    Este artigo procura contribuir para uma reflexão sobre o lugar que a gestão da performance ocupa nas culturas juvenis, focando em particular as percepções dos jovens sobre os consumos de performance, entendidos como o consumo de medicamentos e/ou produtos terapêuticos com finalidades de gestão do desempenho neuro/cognitivo e/ou físico/corporal. A análise tem como base material empírico resultante da componente extensiva de um projecto de pesquisa sobre consumos de performance na população jovem (18-29 anos) em Portugal, designadamente um inquérito por questionário a uma amostra (n =1483) que abrangeu estudantes do ensino superior e trabalhadores sem formação superior. Os resultados revelam...

  5. Histórias de (uma) vida: desafios e dilemas éticos na investigação com idosos

    Pegado, Elsa; Zózimo, Joana; Lopes, Noémia
    Partindo da experiência de investigação num estudo sociológico sobre a psicofarmacologização da velhice, cuja metodologia incluiu a realização de histórias de vida, o presente artigo visa discutir alguns dilemas éticos e correspondentes desafios metodológicos inerentes a esta técnica e, em particular, as especificidades da sua aplicação junto da população idosa. O estudo, desenvolvido no concelho de Almada, contemplou a realização de 30 entrevistas de histórias de vida a idosos a viver sós, com idades compreendidas entre os 67 e os 90 anos, com autonomia física e cognitiva, inseridos em três diferentes contextos (Domicílio, Centros de Dia e Lares).

    Costa, Filipa Alves da; Periquito, Catarina; Carneiro, Maria Clara; Oliveira, Pedro; Fernandes, Ana Isabel; Cavaco-Silva, Patrícia
    "Background: Potentially inappropriate medications (PIMs) are often found in high proportion among the elderly population. The STOPP criteria have been suggested to detect more PIMs in European elderly than the Beers criteria. Objective: This study aimed to determine the prevalence of PIMs and potential prescribing omissions (PPOs) in a sample of Portuguese nursing homes residents. Setting: Four elderly facilities in mainland Portugal Method: A descriptive cross-sectional study was used. Elderly polypharmacy patients were included in the study and their medication (registered in patient clinical records) analysed using the Beers (2012 original version and 2008 version adapted to Portugal), STOPP (Screening...

  8. Gerações saudáveis: intervenções em Saúde Pública com impacto ao longo do ciclo de vida

    Aguiar, João Pedro; Costa, Filipa Alves da
    "Por ocasião da comemoração dos 5 anos de vida do Projeto Geração Saudável, lançado pela Secção Regional do Sul e Regiões Autónomas da Ordem dos Farmacêuticos, tivemos oportunidade de assistir a um interessante debate sobre intervenções em Saúde Pública realizadas noutros países. Foram dados exemplos interessantíssimos e partilhados com entusiasmo pela plateia. No entanto, foram poucos os relatos de iniciativas portuguesas, para além do emblemático projeto Geração Saudável. Há inquestionavelmente um viés de publicação em Portugal, que conduz a que iniciativas louváveis não sejam partilhadas com a comunidade científica. Assim, enquanto docentes da Unidade Curricular de Saúde Pública do Mestrado...

  11. Technology in Parkinson's disease: challenges and opportunities

    Espay, Alberto J., et al.; Movement Disorders Society Task Force on Technology, on behalf of the
    "The miniaturization, sophistication, proliferation, and accessibility of technologies are enabling the capture of more and previously inaccessible phenomena in Parkinson's disease (PD). However, more information has not translated into a greater understanding of disease complexity to satisfy diagnostic and therapeutic needs. Challenges include noncompatible technology platforms, the need for wide-scale and long-term deployment of sensor technology (among vulnerable elderly patients in particular), and the gap between the “big data” acquired with sensitive measurement technologies and their limited clinical application. Major opportunities could be realized if new technologies are developed as part of open-source and/or open-hardware platforms that enable multichannel data...

  14. Commentary: Quantitative home-based assessment of Parkinson’s symptoms: The SENSE-PARK feasibility and usability study

    Godinho, C.; Domingos, J.; Ferreira, J. J.
    "Healthcare professionals and pharmaceutical companies invest a great amount of time and effort in continuously creating electronic health solutions. These technology system developments may represent a step forward in care as ultimately it is not possible to manage what cannot be evaluated. Yet, the use of future generations of technology depends on their specific design, fabrication, distribution, and, most importantly, patients adopting these new technologies as life companions. Data management and the use of artificial intelligence appear as new technological challenges. The overload, sharing and handling of information give rise to new legal, social, and ethical discussions in a field where...

  15. Commentary: A systematic review of the characteristics and validity of monitoring technologies to assess Parkinson’s disease

    Domingos, J.; Godinho, C.; Ferreira, J. J.
    "Technologies may have implications for improving clinical diagnosis and prognosis, and for the development of therapeutic interventions, specific biomarkers, and preventive strategies. Given the amount of existing and ever-growing quantitative assessments using technology in PD, clinicians, patients and researchers are faced with the challenge of deciding which assessment tool to use in the laboratory, clinic and home environment. In order to facilitate this decision-making a systematic review was done to identify and classify the available monitoring technologies for individuals with PD over the last 2 decades. This is a commentary on the systematic review which adds on discussion on some...

  18. I am (not) The Little Mermaid: a case report

    Dias, Maria do Rosário
    "Sarah, currently aged 14Y: 3M, is a late child of a socially differentiated couple, who were already the parents of monozygotic female twins, aged 13Y at the time Sarah was born. Sarah had experienced “double parenting” for years due to her twin sisters, who sequestered and took hold of her under the nonchalant and emotionally detached eyes of her biological parental couple and which led to the development of an identity based on a cleaving of her Self, often projected in repeated drawings of the ‘little mermaid’. Sarah underwent four years of psychoanalytical psychotherapy, initiated in the sequence of marked...
