RESUMEN

Background: Regular physical activity is one of the key components of a healthy lifestyle. It is associated with better physical and cognitive functioning in later life and with increased life expectancy. The purpose of this study was to evaluate the prevalence of, and factors related to, physical inactivity among older adults across Europe. Methods: In this cross-sectional analysis, we used data from participants aged 55 or older in Wave 4 of the Survey of Health, Ageing, and Retirement in Europe (SHARE) database, a multidisciplinary and cross-national panel database covering health, socioeconomic status, and social and family networks. Individuals included in this study were classified as physically active or physically inactive. Clinical, psychosocial and sociodemographic variables were evaluated for their association with physical inactivity. Results: From the total of 58,489 individuals in SHARE, we selected 19,298 people age 55 or older (mean age 67.8 ± 8.9 years; 11,430 (59.2%) female). The overall prevalence of inactivity among individuals age 55 or older in the 16 included countries was 12.5%. The prevalence of physical inactivity varied between countries, ranging from 4.9% (Sweden) to 29% (Portugal). Increasing age, depression, physical limitations, poor sense of meaning in life, social support and memory loss were significant variables associated with physical inactivity. Conclusions: Physical inactivity can be explained by physical, cognitive and psychological conditions. Interventions aimed at promoting physical activity among older people are needed to address this diversity of factors.

RESUMEN

The aim of this work was to evaluate the predictors of mortality in a group of end-stage kidney disease (ESRD) patients under dialysis, by performing a three-year follow-up study. From the 236 patients included in this study, 54 patients died during the three-year follow-up period. Our data showed that the risk of death was higher in patients presenting lower levels of mean cell hemoglobin concentration, transferrin, and albumin. Our study showed that poor nutritional status and an inflammatory-induced iron depleted erythropoiesis are important factors for mortality in these patients.

RESUMEN

Non-adherence to medical plans is recognized as an important problem in dialysis patients, since it has been associated with increased morbidity and mortality, resulting in disproportionately high costs of care. The success of renal replacement therapy depends on the adherence of patients to the different aspects of the therapeutic strategy, which includes a complex drug regimen involving a wide variety of drugs and doses, several prescribed dialysis sessions with different durations, dietetic recommendations and restriction of fluid intake. In this work, we aimed to translate and validate a previously described self-reported end-stage renal disease questionnaire (ESRD-AQ) to the Portuguese language (PESRD-AQ). After ESRD-AQ translation, a validation was performed by experts and by using a cohort of 185 Portuguese dialysis patients. PESRD-AQ reliability analysis showed strong test-retest stability across all items, with an intra-class correlation of 0.931. The average of the item-level content validity index by experts for the 46 items was 0.98, ranging from 0.94 to 1. Moreover, we found that PESRD-AQ scores indicative of non-adherence were associated with alterations in some biological and biochemical markers of non-adherence, including interdialytic weight gain. In conclusion, our results showed that PESRD-AQ, which presented an acceptable reliability and validity, is a valid tool to be used for adherence evaluation by Portuguese-speaking dialysis patients.

RESUMEN

The aim of this study is to evaluate the prevalence and the predictors of difficulty in medication intake across Europe, using a cross-sectional design. We used data from all participants in the wave 4 of the SHARE (Survey of Health, Ageing, and Retirement in Europe) database, which is a cross national European survey. The difficulty in take medication was evaluated using an item from the "Limitations with activities of daily living". Clinical and sociodemographic variables were evaluated as potential predictors. A total of 58 124 individual have been included in this work (mean age=64.9 ± 10.4 years; 43.3% male). The rate of difficulty in taking medication across the 16 European evaluated countries was 2.1%, presenting Spain the highest rate (5.7%) and Switzerland the lowest (0.6%). Increasing age, physical inactivity, physical limitations (mobility, arms function and fine motor limitations, and difficulties in picking up a small coin from a table), a poor sense of meaning in life, and losses in memory and concentration are independent and significant variables associated with difficulty in medication intake across Europe. Predictors of difficulties in medication intake are multicausal, including factors related to physical, cognitive and psychological conditions. Interventions aiming to optimize adherence to medication, particularly in elderly population, need to consider this diversity of determinants.

RESUMEN

siendo el test de aliento con urea carbono-14 (C-14) uno de los métodos de diagnóstico no invasivos; sin embar-go, no ha sido comprobada su utilidad en la población ecuatoriana.Objetivo: Evaluar la sensibilidad y especificidad del test de aliento con urea C-14 para predecir la infección por HP en la población ecuatoriana.Métodos: Estudio de Pruebas Diagnósticas realizado en pacientes que acudieron a la consulta externa del servicio de gastroenterología del Hospital Teófilo Dávila de la ciudad de Machala, en el periodo abril 2018 a marzo 2019. Los pacientes se sometieron a una endoscopia superior de luz blanca (ES) con toma de biopsias para investigar la infec-ción por HP; además, se realizó un test de aliento con urea C-14, para compararla con los resultados de las biopsias.Resultados: Se estudiaron 78 pacientes con una edad media de 33.76±11.2 años. El diagnóstico de gastritis se confirmó a través de la ES e histopatología en el 100% de los pacientes. El test de aliento con urea C-14 fue positi-va en 47/78 (60.3%) pacientes. Se demostró evidencia de infección por HP en biopsias gástricas de 50/78 (64.1%) pacientes. La sensibilidad, especificidad, VPP, VPN, observada y la concordancia entre evaluadores fue de 94%, 100%, 100%, 90%, 96% y 92% (P <0.001), respectivamente.Conclusiones: El test de aliento con urea C-14, es una herramienta útil para predecir infección por HP en la población ecuatoriana


Background: Early detection of Helicobacter pylori infection has become more relevant, with urea carbon-14 (C-14) breath test as one of the non-invasive diagnostic methods; however, it has not been proven in Ecuadorian population.Objective: To evaluate the sensitivity and specificity of the C-14 urea breath test to predict HP infection in the Ecuadorian population.Methods: : Study of diagnostic tests performed on patients who attended the outpatient gastroenterology service of the Hospital Teófilo Dávila in the city of Machala, in the period April 2018 to March 2019. The patients underwent an upper endoscopy of white light (WLE) with biopsies taken to investigate HP infection. In addition, a breath test with C-14 urea was performed to compare it with the biopsies results.Results: 78 patients with a mean age of 33.76±11.2 years were studied. The diagnosis of gastritis was confirmed through endoscopy and histopathology in 100% of the patients. The breath test with urea C-14 was positive in 47/78 (60.3%) patients. Evidence of HP infection was demonstrated in gastric biopsies from 50/78 (64.1%) pa-tients. Sensitivity, specificity, PPV, NPV, and inter-rater reliability were 94%, 100%, 100%, 90%, 96%, and 92% (P <0.001), respectively.Conclusions: The C-14 urea breath test is a useful tool for predicting HP infection in the Ecuadorian population
