Vector Mesons and Dence Skyrmion Matter
2004
In our continuing effort to understand hadronic matter at high density, we have developed a unified field theoretic formalism for dense skyrmion matter using a single Lagrangian to describe simultaneously both matter and meson fluctuations and studied in-medium properties of hadrons. Dropping the quartic Skyrme term, we incorporate into our previous Lagrangian the vector mesons rho and omega in a form which is consistent with the symmetries of QCD. The results that we have obtained, reported here, expose a hitherto unsuspected puzzle associated with the role the omega meson plays at short distance. Since the omega meson couples to baryon density, it leads to a pseudo-gap scenario for the ch…

Years of life that could be saved from prevention of hepatocellular carcinoma
2016
Summary Background Hepatocellular carcinoma (HCC) causes premature death and loss of life expectancy worldwide. Its primary and secondary prevention can result in a significant number of years of life saved. Aim To assess how many years of life are lost after HCC diagnosis. Methods Data from 5346 patients with first HCC diagnosis were used to estimate lifespan and number of years of life lost after tumour onset, using a semi-parametric extrapolation having as reference an age-, sex- and year-of-onset-matched population derived from national life tables. Results Between 1986 and 2014, HCC lead to an average of 11.5 years-of-life lost for each patient. The youngest age-quartile group (18–61 y…
Reflections on communication of disease prognosis and life expectancy by patients with colorectal cancer undergoing palliative care: a qualitative st…
2019
ObjectivesPatients with colorectal cancer undergoing palliative treatment receive extensive treatment-related information throughout their disease trajectory. We aimed to explore the experiences of patients with incurable colorectal cancer while in palliative care and their reflections on the information provided by physicians and nurses. Our main focus was the patients’ thoughts about how information about disease status and life expectancy was communicated, from the first time that they were informed about the incurable nature of their disease through to postsurgery palliative treatment.SettingsPatients with colorectal cancer receiving palliative chemotherapy.Research designWe used a qual…
Global, regional, and national burden of diseases and injuries for adults 70 years and older:systematic analysis for the Global Burden of Disease 201…
2022
AbstractObjectivesTo use data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019) to estimate mortality and disability trends for the population aged ≥70 and evaluate patterns in causes of death, disability, and risk factors.DesignSystematic analysis.SettingParticipants were aged ≥70 from 204 countries and territories, 1990-2019.Main outcomes measuresYears of life lost, years lived with disability, disability adjusted life years, life expectancy at age 70 (LE-70), healthy life expectancy at age 70 (HALE-70), proportion of years in ill health at age 70 (PYIH-70), risk factors, and data coverage index were estimated based on standardised GBD methods.ResultsGlo…
Salud, sexo y comportamiento sexual: la esperanza de vida sexual activa
2021
Resumen: Objetivo: Medir la esperanza de vida sexual activa (EVSA) para estimar la edad promedio a la que finaliza la actividad sexual en la población española, prestando especial atención a la población mayor. Asimismo, se introducen las autopercepciones de la salud y de la salud sexual para observar la variación que producen en la EVSA.Método: Análisis descriptivo transversal. Con los datos de la Human Mortality Database y de la Encuesta Nacional de Salud Sexual para 2009 se calcula la EVSA, mediante el método de Sullivan, clasificando a la población según si ha practicado o no sexo coital en el último año. También se introduce la percepción de la salud y de la salud sexual. Se calcula de…
Factores de riesgo y protección del suicidio en personas mayores: una revisión sistemática
2021
La esperanza de vida se ha incrementado notablemente, no obstante, el suicidio es la principal causa de deceso no natural en la población mayor de 70 años. El objetivo de la presente investigación es revisar sistemáticamente los factores de riesgo y protección en la conducta suicida en personas mayores. Se llevó a cabo una revisión sistemática desde el enfoque PRISMA utilizando las bases de datos: PubMed, LILACS, SciELO, Google Académico y Dialnet. Se emplearon distintos descriptores en términos DeCS y MeSH con el operador booleano “AND” y, finalmente, teniendo en cuenta los criterios de inclusión y exclusión, obtuvimos 27 artículos. Los estudios revisados muestran que entre los factores de…
Effects of Aging and Diet on Cardioprotection and Cardiometabolic Risk Markers.
2019
The prevalence of several diseases increases by age, including cardiovascular diseases, which are the leading cause of morbidity and mortality worldwide. Aging, as a complex process characterized by senescence, triggers various pathways, such as oxidative stress, systemic inflammation, metabolism dysfunction, telomere shortening, mitochondrial dysfunction and deregulated autophagy. A better understanding of the mechanisms underlying senescence may lead to the development of new therapeutic targets and strategies for age-related pathologies and extend the healthy lifespan. Modulating lifestyle risk factors and adopting healthy dietary patterns remain significant tools in delaying the aging …
Vascular aging in rodent models: contrasting mechanisms driving the female and male vascular senescence
2021
Increasing scientific interest has been directed to sex as a biological and decisive factor on several diseases. Several different mechanisms orchestrate vascular function, as well as vascular dysfunction in cardiovascular and metabolic diseases in males and females. Certain vascular sex differences are present throughout life, while others are more evident before the menopause, suggesting two important and correlated drivers: genetic and hormonal factors. With the increasing life expectancy and aging population, studies on aging-related diseases and aging-related physiological changes have steeply grown and, with them, the use of aging animal models. Mouse and rat models of aging, the most…
