Disabil Health J

October 2024

National Center for Epidemiology, Institute of Health Carlos III, Madrid, Spain; Consortium for Biomedical Research in Neurodegenerative Diseases (CIBERNED), Madrid, Spain.

Background: Disability and chronic diseases are prevalent conditions associated with mortality, but little information is available on their potential synergistic effects.

Objective: This study aimed to describe additive interactions between disability and chronic diseases on mortality risk in middle-aged and older adults.

Methods: A representative cohort of 22,800 community-dwelling Spanish people aged 50 years or older were interviewed for disability with the Global Activity Limitation Indicator and specific chronic diseases in the 2011-12 and 2014 National Health Surveys and subsequently followed up for mortality.

Evidence-based medicine (EBM) can be an unfamiliar territory for those working in tumor pathology research, and there is a great deal of uncertainty about how to undertake an EBM approach to planning and reporting histopathology-based studies. In this article, reviewed and endorsed by the Word Health Organization International Agency for Research on Cancer's International Collaboration for Cancer Classification and Research, we aim to help pathologists and researchers understand the basics of planning an evidence-based tumor pathology research study, as well as our recommendations on how to report the findings from these. We introduce some basic EBM concepts, a framework for research questions, and thoughts on study design and emphasize the concept of reporting standards.

Objective: Interruptions in care of people with HIV (PWH) on antiretroviral therapy (ART) are associated with adverse outcomes, but most studies have relied on composite outcomes. We investigated whether mortality risk following care interruptions differed from mortality risk after first starting ART.

Design: Collaboration of 18 European and North American HIV observational cohort studies of adults with HIV starting ART between 2004 and 2019.

Quality of plant-based diets and frailty incidence: a prospective analysis of UK biobank participants.

Age Ageing

May 2024

Department of Preventive Medicine and Public Health, School of Medicine, Universidad Autónoma de Madrid, Calle del Arzobispo Morcillo, 4, 28029 Madrid, Spain.

Article Synopsis
  • Study examined how two types of plant-based diets affect the risk of physical frailty in adults aged 40 to 70 in the UK over approximately 6.7 years.
  • Healthy Plant-based Diet Index (hPDI) showed a significantly lower risk of frailty, while the Unhealthful Plant-based Diet Index (uPDI) was linked to a higher risk.
  • Results suggest that eating more healthy plant foods is beneficial for maintaining physical strength, whereas consuming unhealthy plant foods can lead to increased frailty.

Objective: To forecast the annual burden of type 2 diabetes and related socio-demographic disparities in Belgium until 2030.

Methods: This study utilized a discrete-event transition microsimulation model. A synthetic population was created using 2018 national register data of the Belgian population aged 0-80 years, along with the national representative prevalence of diabetes risk factors obtained from the latest (2018) Belgian Health Interview and Examination Surveys using Multiple Imputation by Chained Equations (MICE) as inputs to the Simulation of Synthetic Complex Data (simPop) model.

Department of Preventive Medicine and Public Health, School of Medicine, Universidad Autónoma de Madrid, Madrid, Spain.

Article Synopsis
  • A study examined the link between dietary vitamin C intake and changes in chronic pain among adults aged 60 and older, finding that higher vitamin C intake is connected to improved pain outcomes.
  • Data from two cohorts involving over 1,700 participants were analyzed, showing that 40.3% experienced worsening pain while 42.5% reported improvement over an average of 2.6 years.
  • Results indicated that those in the highest vitamin C intake group were more likely to experience pain improvement, lower frequency, and fewer pain locations, suggesting potential benefits of increasing dietary vitamin C for pain management.

Objective: The incidence of type 2 diabetes mellitus (T2DM) has risen dramatically. Among people living with HIV (PLHIV), chronic disease (now >15 cases/1000 in the general population worldwide) and long-term exposure to antiretroviral therapy (ART) can alter metabolic processes early, favoring insulin resistance and T2DM. We retrospectively studied the incidence of T2DM and associated factors in the Cohort of the Spanish AIDS Research Network, a prospective cohort of PLHIV enrolled at diagnosis and before initiation of ART.

The discussion has revolved around the derivatives of amino acids and peptides containing carbocycles and their potential antiviral activity in vitro against influenza A, hepatitis C viruses, and coronavirus. Studies conducted on cell cultures reveal that aminoadamantane amino acid derivatives exhibit the capacity to hinder the replication of viruses containing viroporins. Furthermore, certain compounds demonstrate potent virucidal activity with respect to influenza A/H5N1 and hepatitis C virus particles.

Introduction: Given the absence of international guidelines on the joint management and control of tuberculosis (TB) and type 2 diabetes mellitus (T2D), the World Health Organization (WHO) and the International Union Against Tuberculosis and Lung Disease (The Union) launched in 2011 a policy framework to address the growing syndemic burden of TB-T2D. This review aimed at mapping the available evidence on the implementation of the Union-WHO Framework, explicitly, or bi-directional TB-T2D health programs as an initiative for co-management in patients in low- and middle-income countries (LMIC).

Methods: A rapid review was performed based on a systematic search in PubMed and Web of Science electronic databases for peer-reviewed articles on The Union-WHO Framework and bi-directional interventions of TB and T2D in LMIC.

Article Synopsis
  • A study was conducted to investigate the effects of traffic-related air pollution (TRAP) on oxidative stress and metabolic profiles in residents of Spain, highlighting that human studies on this topic are limited.
  • Researchers analyzed traffic density around participants' homes and measured plasma metabolomic profiles and urine oxidative stress biomarkers from 1181 individuals using advanced spectroscopy techniques.
  • Key findings showed that higher traffic density was linked to changes in certain plasma metabolites and oxidative stress markers, suggesting that these metabolic alterations may be influenced by oxidative stress resulting from traffic exposure.

  • Inorganic arsenic exposure may heighten the risk of cardiovascular disease and overall mortality by contributing to accelerated aging, which can be gauged through specific DNA methylation measures.
  • The study, conducted with American Indian adults, assessed three epigenetic aging measures (PhenoAge, GrimAge, DunedinPACE) to see how they mediated the effects of arsenic on cardiovascular health outcomes.
  • Findings revealed that higher urinary arsenic levels correlated with older biological ages in GrimAge and faster aging in DunedinPACE, indicating a significant link between arsenic exposure, accelerated aging, and increased cardiovascular risks.
