Relationship between health-related fitness and quality of life in elderly with type 2 diabetes: an exploratory study in the province of Seville

Under a Creative Commons license.[Objetivos]: Caracterizar a la población adulta-mayor afectada por diabetes mellitus tipo 2 (DM2) tratada en las consultas de atención primaria en cuanto al nivel de condición física relacionada con la salud (CFRS) y calidad de vida relacionada con la salud (CVRS), y por otro lado, corroborar si existe relación entre los diferentes test de CFRS y la CVRS. [Método]: Se utilizó un diseño transversal observacional de casos y controles para comparar la CFRS y la CVRS (evaluada mediante el cuestionario EQ-5D-3L) entre 42 pacientes con DM2 y 54 pacientes sin DM2, y se estableció la relación existente entre la CFRS y la CVRS en los pacientes con DM2. [Resultados]: En cuanto a la CFRS, los pacientes con DM2 obtuvieron mayores resultados en el test de dinamometría manual que sus pares sin dicha afección (p < 0,025). Los valores alcanzados en el test sit and reach fueron mayores en el grupo control que en el grupo DM2 (p < 0,001). No se detectaron diferencias estadísticamente significativas en cuanto a la CVRS entre ambos grupos. El coeficiente de correlación de Pearson desveló un nivel de correlación de moderado a alto entre los componentes de la CVRS y los test de fuerza, movilidad y equilibrio que componen la CFRS (p < 0,05). [Conclusiones]: Este estudio muestra la asociación existente entre la CVRS evaluada con el EQ-5D-3L y los test de fuerza, movilidad y equilibrio dinámico en pacientes con DM2 tratados en atención primaria, cualidades vitales para el desarrollo de las actividades de la vida diaria de estos pacientes.[Objectives]: To characterize the type 2 diabetic (DM2) population treated in primary care consultations in regard of Health-Related Fitness (HRF) and Health-Related Quality of Life (HRQoL), and, on the other hand, to confirm if there is a relationship between HRF and HRQoL in DM2 patients. [Methods]: A cross-sectional, observational, case-control study was performed to compare the HRF and HRQoL between 42 DM2 patients and 54 patients without DM2 and the relationship between these two concepts was revealed. [Results]: In regard of HRF, statistically significant differences were found in the hand dynamometer test in favor of DM2 patients group (p = , 025) and statistically significant differences were achieved in favor of the reference group in sit and reach test (p = , 001). Pearson's correlation coefficient revealed a moderate to high level of correlation between the different dimensions and index of EQ-5D-3L and strength, mobility and balance tests (p < ,05). [Conclusions]: This study showsthe relationship between EQ-5D-3L componentsand strength, mobility and balance tests in DM2 patients treated in primary care, key functional capacities to a correct development of daily activities in these patients.A los autores del presente trabajo les gustaría agradecer la colaboración prestada por el Centro de Salud Los Bermejales por financiar parcialmente este proyecto.Open Access funded by Consejería de Educación, Cultura y Deporte de la Junta de Andalucía.Peer Reviewe

Caveolin-1 Modulates Mechanotransduction Responses to Substrate Stiffness through Actin-Dependent Control of YAP

The transcriptional regulator YAP orchestrates many cellular functions, including tissue homeostasis, organ growth control, and tumorigenesis. Mechanical stimuli are a key input to YAP activity, but the mechanisms controlling this regulation remain largely uncharacterized. We show that CAV1 positively modulates the YAP mechanoresponse to substrate stiffness through actin-cytoskeleton-dependent and Hippo-kinase-independent mechanisms. RHO activity is necessary, but not sufficient, for CAV1-dependent mechanoregulation of YAP activity. Systematic quantitative interactomic studies and image-based small interfering RNA (siRNA) screens provide evidence that this actin-dependent regulation is determined by YAP interaction with the 14-3-3 protein YWHAH. Constitutive YAP activation rescued phenotypes associated with CAV1 loss, including defective extracellular matrix (ECM) remodeling. CAV1-mediated control of YAP activity was validated in vivo in a model of pancreatitis-driven acinar-to-ductal metaplasia. We propose that this CAV1-YAP mechanotransduction system controls a significant share of cell programs linked to these two pivotal regulators, with potentially broad physiological and pathological implications. Moreno-Vicente et al. report that CAV1, a key component of PM mechanosensing caveolae, mediates adaptation to ECM rigidity by modulating YAP activity through the control of actin dynamics and phosphorylation-dependent interaction of YAP with the 14-3-3-domain protein YWHAH. Cav1-dependent YAP regulation drives two pathophysiological processes: ECM remodeling and pancreatic ADM. © 2018 The Author

Eosinophilic Panniculitis and Insect Bite-Like Eruption in a Patient with Chronic Lymphocytic Leukaemia: A Spectrum of the Same Entity

Background. Eosinophilic dermatosis of hematologic disorders is a reactive process that may cause a variety of clinical manifestations. Methods. We report a patient who had outbreaks of skin lesions since the onset of chronic lymphocytic leukaemia. Results. The cutaneous eruptions began as eosinophilic panniculitis and after changed to insect bite-like lesions. Conclusion. We think that eosinophilic panniculitis and insect bite-like lesions may be part of the spectrum of the same entity in patients with hematologic disorders

Caveolin-1 is required for TGF-β-induced transactivation of the EGF receptor pathway in hepatocytes through the activation of the metalloprotease TACE/ADAM17

Transforming growth factor-beta (TGF-β) plays a dual role in hepatocytes, inducing both pro- and anti-apoptotic responses, whose balance decides cell fate. Survival signals are mediated by the epidermal growth factor receptor (EGFR) pathway, which is activated by TGF-β in these cells. Caveolin-1 (Cav1) is a structural protein of caveolae linked to TGF-β receptors trafficking and signaling. Previous results have indicated that in hepatocytes, Cav1 is required for TGF-β-induced anti-apoptotic signals, but the molecular mechanism is not fully understood yet. In this work, we show that immortalized Cav1(-/-) hepatocytes were more sensitive to the pro-apoptotic effects induced by TGF-β, showing a higher activation of caspase-3, higher decrease in cell viability and prolonged increase through time of intracellular reactive oxygen species (ROS). These results were coincident with attenuation of TGF-β-induced survival signals in Cav1(-/-) hepatocytes, such as AKT and ERK1/2 phosphorylation and NFκ-B activation. Transactivation of the EGFR pathway by TGF-β was impaired in Cav1(-/-) hepatocytes, which correlated with lack of activation of TACE/ADAM17, the metalloprotease responsible for the shedding of EGFR ligands. Reconstitution of Cav1 in Cav1(-/-) hepatocytes rescued wild-type phenotype features, both in terms of EGFR transactivation and TACE/ADAM17 activation. TACE/ADAM17 was localized in detergent-resistant membrane (DRM) fractions in Cav1(+/+) cells, which was not the case in Cav1(-/-) cells. Disorganization of lipid rafts after treatment with cholesterol-binding agents caused loss of TACE/ADAM17 activation after TGF-β treatment. In conclusion, in hepatocytes, Cav1 is required for TGF-β-mediated activation of the metalloprotease TACE/ADAM17 that is responsible for shedding of EGFR ligands and activation of the EGFR pathway, which counteracts the TGF-β pro-apoptotic effects. Therefore, Cav1 contributes to the pro-tumorigenic effects of TGF-β in liver cancer cells.This work was supported by grants from: (1) the Ministry of Economy and Competitiveness (MINECO), Spain (BFU2012-35538 and ISCIII-RTICC: RD12-0036-0029 to IF; SAF2013-43713 to PM-S; BFU2012-33932 to GE; SAF2011-25047 and CSD2009-00016 to MAdP); (2) AGAUR-Generalitat de Catalunya (2009SGR-312 to IF); and (3) People Programme (Marie Curie Actions) of the European Union’s Seventh Framework Programme (FP7/2007-2013) under REA grant agreement no.
