Common Law, Charity, and Human Rights as Responses to the Socio-Economic Crisis in Galicia, Spain

This article presents the findings of a research project analyzing the effects of the Spanish socio-economic crisis on rural areas. It describes the perceptions of social workers in the public sector engaged in community practice and the perceptions of social leaders working for public and private human service organizations within the province of Ourense, Spain. It explores how the current economic crisis has affected people, health care units and the social workers’ scope of action. The study relied on secondary data, surveys and qualitative interviews. Study findings suggest that the adopted measures for responding to the effects of the crisis have been scarce. The primary responses to the crisis include privatization of human services and the transfer of responsibility from government to civil society organizations. Instead of focusing on charity, this study in Galicia, Spain proposes a greater focus on rural social work and on the promotion and defense of human rights by civic and other organizations

Metal Node Control of Brønsted Acidity in Heterobimetallic Titanium–Organic Frameworks

Compared to indirect framework modification, synthetic control of cluster composition can be used to gain direct access to catalytic activities exclusive of specific metal combinations. We demonstrate this concept by testing the aminolysis of epoxides with a family of isostructural mesoporous frameworks featuring five combinations of homometallic and heterobimetallic metal-oxo trimers (Fe3, Ti3, TiFe2, TiCo2, and TiNi2). Only TiFe2 nodes display activities comparable to benchmark catalysts based on grafting of strong acids, which here originate from the combination of Lewis Ti4+ and Brønsted Fe3+–OH acid sites. The applicability of MUV-101(Fe) to the synthesis of β-amino alcohols is demonstrated with a scope that also includes the gram scale synthesis of propranolol, a natural β-blocker listed as an essential medicine by the World Health Organization, with excellent yield and selectivity

Instructors’ teaching styles: relation with competences, self-efficacy, and commitment in pre-service teachers

Instructors’ teaching styles in higher education are an issue of major importance because these interactions affect students’ self-perceptions, involvement, and achievement. This study aimed to test a theoretical model of relations between perceived teaching styles (autonomy support, structure, and control) and competences, self-efficacy, and commitment in pre-service teachers; to assess the invariance of the model in two samples; and to analyze the mediated relations between these variables. Measures were collected from 842 Spanish pre-service teachers. As main research implications, teaching styles predicted acquired competences, competences predicted teaching self-efficacy, and self-efficacy predicted commitment to the profession. This model was equivalent in two samples of childhood and primary education pre-service teachers. Competences and self-efficacy mediated the relationships between variables. As practical implications, this study clearly shows the need for different interventions to enhance adequate instructors’ teaching styles and to foster among novice pre-service teachers the acquisition of professional competences, initial self-efficacy, and a good level of commitment to their profession

Returning to work in cancer survivors: a multi-center cross-sectional study in Spain

Objetivo: Analizar la situación laboral, así como variables sociodemográficas (edad, sexo, estado civil y titulación) relacionadas con el cáncer (tipo de cáncer, estrategia de tratamiento primario y fase de supervivencia) en supervivientes españoles de cáncer. Método y procedimiento: Estudio transversal sobre una muestra heterogénea de 772 supervivientes de cáncer de inicio en la edad adulta en edad laboral. Se realizaron análisis correlacionales y de regresión logística para estudiar la capacidad predictiva de las variables sociodemográficas y relacionadas con el cáncer sobre la situación laboral y la posible modulación de los resultados por la CVRS evaluada mediante el QLACS. Resultados: Sólo el 55% de los supervivientes de cáncer estaban empleados. La edad, la cualificación y el tipo de cáncer fueron predictores independientes de la situación laboral, así como de la fase de supervivencia en los supervivientes con una CVRS baja. Conclusiones: Un alto porcentaje de supervivientes en edad laboral no vuelve a trabajar tras la experiencia oncológica. Algunas variables sociodemográficas y relacionadas con la enfermedad pueden ayudar a la identificación precoz de la población de riesgo en la que centrar la atención. Objective: To analyze the employment status as well as sociodemographic (age, gender, marital status, and qualification) and cancer-related variables (cancer type, primary treatment strategy, and survival phase) in Spanish cancer survivors. Method and procedure: Cross-sectional study on a heterogeneous sample of 772 working-age survivors of adult-onset cancer. Correlational and logistic regression analyses were performed to study the predictive ability of sociodemographic and cancer-related variables on employment status and the possible modulation of results by HRQOL assessed by the QLACS. Results: Only 55% of cancer survivors were employed. Age, qualification, and type of cancer were independent predictors of employment status as well as the survival phase in survivors with a low HRQOL. Conclusions: A high percentage of working-age survivors do not return to work after the cancer experience. Some sociodemographic and disease-related variables can help in the early identification of the risk population on which to focus attention

Cognitive impairment in a murine model of experimental autoimmune encephalomyelitis with relapsing-remitting course

Multiple sclerosis (MS) is a neuroinflammatory disorder characterized by demyelination and progressive axonal loss that affects the central nervous system. In addition of physical disability and the neurodegenerative process, MS associates with co-morbid behavioral, neuropsychiatric and cognitive impairment, including learning and memory deficits. The study of cognitive impairment in the currently most suitable experimental animal model of MS, experimental autoimmune encephalomyelitis (EAE), constitutes a very valuable tool to translate ultimately into clinical a better diagnosis and more effective treatment protocols. In our study, we analyzed the behavioral profile of a murine model of EAE induced by myelin oligodendrocyte glycoprotein peptide (MOG35-55) which develops a relapsing-remitting course. In the early neuroinflammatory phase of the disease, i.e. 19-21 days post immunization (dpi), EAE mice exhibited deficits in motor coordination/skill learning (Rotarod test), and spatial working memory (spontaneous alternation in Y-maze), as well as depressive symptoms (tail suspension test) and anxiety-like behavior (elevated plus-maze). EAE mice did not yet show object recognition memory impairments, suggesting that reference memory was not altered in this phase. However, from 33-35 dpi until late phases (49-52 dpi), independently of clinical score, EAE mice exhibited a memory decline showing lower discrimination index in the object recognition test. EAE late phase was also characterized by motor coordination and spatial working memory impairments as well as higher anxiety-like behavior. Overall, these data demonstrates a differential pattern of gradual cognitive dysfunctions during the relapsing-remitting EAE course that could help to understand the development of progressive cognitive decline in MS patients.

Combined use of smartphone and smartband technology in the improvement of lifestyles in the adult population over 65 years: study protocol for a randomized clinical trial (EVIDENT-Age study)

Background The increasing use of smartphones by older adults also increases their potential for improving different aspects of health in this population. Some studies have shown promising results in the improvement of cognitive performance through lifestyle modification. All this may have a broad impact on the quality of life and carrying out daily living activities. The objective of this study is to evaluate the effectiveness of combining the use of smartphone and smartband technology for 3 months with brief counseling on life habits, as opposed to providing counseling only, in increasing physical activity and improving adherence to the Mediterranean diet. Secondary objectives are to assess the effect of the intervention on body composition, quality of life, independence in daily living activities and cognitive performance. Methods This study is a two-arm cluster-randomized trial that will be carried out in urban health centers in Spain. We will recruit 160 people aged between 65 and 80 without cardiovascular disease or cognitive impairment (score in the Mini-mental State Examination ≥24). On a visit to their center, intervention group participants will be instructed to use a smartphone application for a period of 3 months. This application integrates information on physical activity received from a fitness bracelet and self-reported information on the patient’s daily nutritional composition. The primary outcome will be the change in the number of steps measured by accelerometer. Secondary variables will be adherence to the Mediterranean diet, sitting time, body composition, quality of life, independence in daily living activities and cognitive performance. All variables will be measured at baseline and on the assessment visit after 3 months. A telephone follow-up will be carried out at 6 months to collect self-reported data regarding physical activity and adherence to the Mediterranean diet. Discussion Preventive healthy aging programs should include health education with training in nutrition and lifestyles, while stressing the importance of and enhancing physical activity; the inclusion of new technologies can facilitate these goals. The EVIDENT-AGE study will incorporate a simple, accessible intervention with potential implementation in the care of older adults.This study was supported in part by grants funded by the Instituto de Salud Carlos III, Institute of Biomedical Research of Salamanca (IBSAL)-IBY17/00003, and the Spanish Research Network for Preventive Activities and Health Promotion in Primary Care (REDIAPP)-RD16/0007

STARD1 promotes NASH-driven HCC by sustaining the generation of bile acids through the alternative mitochondrial pathway

Background & Aims Besides their physiological role in bile formation and fat digestion, bile acids (BAs) synthesised from cholesterol in hepatocytes act as signalling molecules that modulate hepatocellular carcinoma (HCC). Trafficking of cholesterol to mitochondria through steroidogenic acute regulatory protein 1 (STARD1) is the rate-limiting step in the alternative pathway of BA generation, the physiological relevance of which is not well understood. Moreover, the specific contribution of the STARD1-dependent BA synthesis pathway to HCC has not been previously explored. Methods STARD1 expression was analyzed in a cohort of human non-alcoholic steatohepatitis (NASH)-derived HCC specimens. Experimental NASH-driven HCC models included MUP-uPA mice fed a high-fat high-cholesterol (HFHC) diet and diethylnitrosamine (DEN) treatment in wild-type (WT) mice fed a HFHC diet. Molecular species of BAs and oxysterols were analyzed by mass spectrometry. Effects of NASH-derived BA profiles were investigated in tumour-initiated stem-like cells (TICs) and primary mouse hepatocytes (PMHs). Results Patients with NASH-associated HCC exhibited increased hepatic expression of STARD1 and an enhanced BA pool. Using NASH-driven HCC models, STARD1 overexpression in WT mice increased liver tumour multiplicity, whereas hepatocyte-specific STARD1 deletion (Stard1ΔHep) in WT or MUP-uPA mice reduced tumour burden. These findings mirrored the levels of unconjugated primary BAs, β-muricholic acid and cholic acid, and their tauroconjugates in STARD1-overexpressing and Stard1ΔHep mice. Incubation of TICs or PMHs with a mix of BAs mimicking this profile stimulated expression of genes involved in pluripotency, stemness and inflammation. Conclusions The study reveals a previously unrecognised role of STARD1 in HCC pathogenesis, wherein it promotes the synthesis of primary BAs through the mitochondrial pathway, the products of which act in TICs to stimulate self-renewal, stemness and inflammation. Lay summary Effective therapy for hepatocellular carcinoma (HCC) is limited because of our incomplete understanding of its pathogenesis. The contribution of the alternative pathway of bile acid (BA) synthesis to HCC development is unknown. We uncover a key role for steroidogenic acute regulatory protein 1 (STARD1) in non-alcoholic steatohepatitis-driven HCC, wherein it stimulates the generation of BAs in the mitochondrial acidic pathway, the products of which stimulate hepatocyte pluripotency and self-renewal, as well as inflammation.We acknowledge support from grants PID2019-111669RB-100, SAF2017-85877R and SAF2015-73579-JIN from Plan Nacional de I+D funded by the Agencia Estatal de Investigación (AEI), the Fondo Europeo de Desarrollo Regional (FEDER) and CIBEREHD; the center grant P50AA011999 Southern California Research Center for ALPD and Cirrhosis funded by NIAAA / NIH; as well as support from AGAUR of the Generalitat de Catalunya SGR-2017-1112, European Cooperation in Science & Technology (COST) ACTION CA17112 Prospective European Drug-Induced Liver Injury Network, the ‘ER stress-mitochondrial cholesterol axis in obesity-associated insulin resistance and comorbidities’-Ayudas FUNDACION BBVA and the Red Nacional 2018-102799-T de Enfermedades Metabólicas y Cáncer, and Project 201916/31 "Contribution of mitochondrial oxysterol and bile acid metabolism to liver carcinogenesis" 2019 by Fundació Marato TV3.

Glycemic markers and relation with arterial stiffness in Caucasian subjects of the MARK study

[EN]BACKGROUND: Effect of prediabetes and normal glucose on arterial stiffness remains controversial. The primary aim of this study was to investigate the relationship of fasting plasma glucose (FPG), postprandial glucose (PG) and glycosylated haemoglobin (HbA1c) with brachial-ankle pulse wave velocity (baPWV) and cardio-ankle vascular index (CAVI) in Caucasian adults. The secondary aim was to analyse this relationship by glycaemic status. METHODS: Cross-sectional study. Setting: Primary care. Participants: 2,233 subjects, 35-74 years. Measures: FPG (mg/dL) and HbA1c (%) of all subjects were measured using standard automated enzymatic methods. PG (mg/dL) was self-measured at home two hours after meals (breakfast, lunch and dinner) for one day using an Accu-chek ® glucometer. CAVI was measured using a VaSera VS-1500® device (Fukuda Denshi), and baPWV was calculated using a validated equation. RESULTS: CAVI and baPWV values were significantly higher in subjects with diabetes mellitus than in glucose normal and prediabetes groups (p<0.001). FPG, PG and HbA1c were positively associated with CAVI and baPWV. The β regression coefficient for: HbA1c was 0.112 (CI 95% 0.068 to 0.155) with CAVI, 0.266 (CI 95% 0.172 to 0.359) with baPWV; for PG was 0.006 (CI 95% 0.004 to 0.009 and for FPG was 0.005 (CI 95% 0.002 to 0.008) with baPWV; and for PG was 0.002 (CI 95% 0.001 to 0.003) and 0.003 (CI 95% 0.002 to 0.004) with CAVI (p<0.01 in all cases). When analysing by hyperglycaemic status, FPG, PG and HbA1c were positively associated with CAVI and baPWV in subjects with type 2 diabetes mellitus. CONCLUSION: FPG, PG and HbA1c show a positive association with CAVI and baPWV, in Caucasian adults with intermediate cardiovascular risk factors. When analysing by hyperglycaemic status, the association is only maintained in subjects with type 2 diabetes mellitus
