Convergent and discriminative validity of the Frail-VIG index with the EQ-5D-3L in people cared for in primary health care
2021
Abstract Background The Frail-VIG frailty index has been developed recently. It is an instrument with a multidimensional approach and a pragmatic purpose that allows rapid and efficient assessment of the degree of frailty in the context of clinical practice. Our aim was to investigate the convergent and discriminative validity of the Frail-VIG frailty index with regard to EQ-5D-3L value. Methods We carried out a cross-sectional study in two Primary Health Care (PHC) centres of the Catalan Institute of Health (Institut Català de la Salut), Barcelona (Spain) from February 2017 to January 2019. Participants in the study were all people included under a home care programme during the study peri…
Psychometric properties of the Norwegian version of the Kidscreen-27 questionnaire
2016
Background The Norwegian version of the Kidscreen-27, a measure of generic health-related quality of life, has not yet been validated. Thus, the aim of this study was to investigate the reliability and validity of the Norwegian Kidscreen-27, in 10 year-old children. Methods The Kidscreen-27 consists of five domains and was validated in a cross-sectional study of 1085 school children (52.5 % boys). In addition a subsample of 56 children also had repeated measures in order to study test-retest reliability. Results Cronbach's alpha values ranged from 0.73 to 0.83, while intraclass correlation values over time ranged from 0.71 to 0.81. The domains of physical well-being, psychological well-bein…

12 páginas Objetivos: Validar las escalas de Bienestar Psicológico de Ryff en enfermería y relacionarlas con variables clave en calidad de vida laboral. Materiales y método: participaron por encuesta electrónica autoadministrada anónima 433 profesionales, 33.1% profesionales de enfermería (n=123) en quienes nos centramos. Además de sociodemográficos, se recogió información sobre bienestar psicológico, atención consciente, afrontamiento de la muerte y calidad de vida. La validez de constructo fue evaluada con análisis factorial confirmatorio. Se estimó fiabilidad y se recogieron evidencias de validez externa. Resultados: El modelo mostró ajuste adecuado: c2(362) = 438.59 (p = .01), CFI = .98…
Main Problems of Diabetes Mellitus Type 2 Patients in Keeping Diet
2015
A research has been carried out to assess the awareness of patients about the importance of diet, the availability of information and to make the diabetes patients with mellitus type 2 realize the urgency of dieting. The first part looks into theoretical sources and statistics about how widespread diabetes mellitus type 2 is and the importance of a healthy diet. The practical part of the research consists of the survey results. The method of quantitative research was applied. The conclusions and suggestions have been made based on the research results.
Subjective health literacy : Development of a brief instrument for school-aged children
2016
Aims: The present paper focuses on the measurement of health literacy (HL), which is an important determinant of health and health behaviours. HL starts to develop in childhood and adolescence; hence, there is a need for instruments to monitor HL among younger age groups. These instruments are still rare. The aim of the project reported here was, therefore, to develop a brief, multidimensional, theory-based instrument to measure subjective HL among school-aged children. Methods: The development of the instrument covered four phases: item generation based on a conceptual framework; a pilot study ( n = 405); test–retest ( n = 117); and construction of the instrument ( n = 3853). All the samp…
Effects of waterborne iron overload and simulated winter conditions on acute physiological stress response of whitefish, Coregonus lavaretus
2003
Two-year-old whitefish (Coregonus lavaretus) were exposed for 30 days to episodic iron overload in iron-rich humic water (5%) supplemented with inorganic iron (5 mg FeL(-1)). Two parallel laboratory exposures were performed, one under conditions simulating winter and the other under conditions simulating spring. After exposure, some of the fish were subjected to acute handling stress in the form of a short air challenge to reveal possible modification of the primary and secondary stress responses. In whitefish sampled without additional handling, iron accumulated in the liver (under spring conditions) and gills (under winter and spring conditions); plasma catecholamine and beta-estradiol (b…
Attenuated Carbohydrate and Gill Na+ , K+-ATPase Stress Responses in Whitefish Caged near Bleached Kraft Mill Discharges
2002
Exposure to biologically treated bleached kraft mill effluent (BKME) is demonstrated to greatly modify the acute physiological stress response in fish and, accordingly, to lead to inconsistencies in data interpretation due to dissimilar effects of handling procedures on reference and exposed fish. To consider this phenomenon, juvenile whitefish (Coregonus lavaretus) were caged for 30 days in four reference sites and in three areas influenced by different BKME discharges. After exposure, fish were subjected to the impacts of low-level handling by raising the cages to the water surface, serially handnetting the fish, and transferring ( approximately 10 min) the submerged cages to the research…
Establishment of a quantitative RT-pCR for detection of vascular cell adhesion molecule-1 transcripts in endothelial cells after stimulation with adv…
1998
Advanced glycation endproducts (AGE) are supposed to increase endothelial expression of adhesion molecules like vascular cell adhesion molecule-1 (VCAM-1) by inducing an intracellular stress with subsequent activation of nuclear transcription factor NF-kappa-B. Quantitative analysis of VCAM-1-transcription has not been demonstrated concerning this topic. Thus, the aim of this study was to establish quantitative reverse transcription polymerase chain reaction (RT-PCR) assays using a spacer gene in order to measure the amounts of specific mRNA for VCAM-1 in human umbilical vein endothelial cells (HUVEC) which were stimulated with AGE-albumin (AGE-BSA). A recombinant RNA-standard was synthesiz…
Model-based biotechnological potential analysis of Kluyveromyces marxianus central metabolism
2016
Abstract The non-conventional yeast Kluyveromyces marxianus is an emerging industrial producer for many biotechnological processes. Here, we show the application of a biomass-linked stoichiometric model of central metabolism that is experimentally validated, and mass and charge balanced for assessing the carbon conversion efficiency of wild type and modified K. marxianus. Pairs of substrates (lactose, glucose, inulin, xylose) and products (ethanol, acetate, lactate, glycerol, ethyl acetate, succinate, glutamate, phenylethanol and phenylalanine) are examined by various modelling and optimisation methods. Our model reveals the organism’s potential for industrial application and metabolic engi…
In syringe hybrid monoliths modified with gold nanoparticles for selective extraction of glutathione in biological fluids prior to its determination …
2020
Abstract In this work, a simple device for extraction glutathione (GSH) in biological fluids using a hybrid monolithic material within a polypropylene syringe is developed. For this purpose, glycidyl methacrylate-based monolith was firstly prepared within this housing material, and the polymer was modified with different ligands (ammonia, cysteamine and cystamine). The resulting materials (containing amine or thiol groups, respectively) were then functionalized with gold nanoparticles (AuNPs). The hybrid material that gave the largest AuNPs coverage was selected as solid-phase (SPE) sorbent and several variables affecting the extraction recovery of this compound were investigated. Under opt…
