Traducción y adaptación transcultural al contexto español del marco teórico Person-Centred Practice Framework

Background. Person-centered care has become a key global approach that seeks to provide answers to all factors of the complex health care-related processes. This has led to the development of theoreti-cal frameworks that represent the components of person-centered care. The internationally recognized Person-Centred Practice Framework (PCPF) (McCormack and McCance) allows multidisciplinary teams to understand and operationalize the dimensions for the development of person-centered care. The aim of this study was to obtain the first Spanish version of the PCPF translated and adapted to the Spanish con-text. Methods. We translated the PCPF following the Translation and cul-tural adaptation process for Patient-Reported Outcomes (PRO) Measures guidelines. A consulting session with experts was part of the process and content validation on clarity and relevance for each domain was performed. Results. We encountered no significant difficulties to reach agree-ments on most of the terms except for Having a sympathetic presence. Not only was a complex term to translate but also to trans-culturally adapt. Regarding relevance and clarity, the content index by construct (I-CVI) and the global framework (S-CVI/Ave) were consistent with their original counterparts (>= 0.90). Conclusions. The adapted Spanish version is clear, significant, and conceptually equivalent to the original PCPF. It will allow a better com-prehension of the person-centered practice framework in the Spanish context and facilitate the implementation of this approach in clinical practices

Toll-like receptor signaling and stages of addiction

Athina Markou and her colleagues discovered persistent changes in adult behavior following adolescent exposure to ethanol or nicotine consistent with increased risk for developing addiction. Building on Dr. Markou's important work and that of others in the field, researchers at the Bowles Center for Alcohol Studies have found that persistent changes in behavior following adolescent stress or alcohol exposure may be linked to induction of immune signaling in brain. This study aims to illuminate the critical interrelationship of the innate immune system (e.g., toll-like receptors [TLRs], high-mobility group box 1 [HMGB1]) in the neurobiology of addiction. This study reviews the relevant research regarding the relationship between the innate immune system and addiction. Emerging evidence indicates that TLRs in brain, particularly those on microglia, respond to endogenous innate immune agonists such as HMGB1 and microRNAs (miRNAs). Multiple TLRs, HMGB1, and miRNAs are induced in the brain by stress, alcohol, and other drugs of abuse and are increased in the postmortem human alcoholic brain. Enhanced TLR-innate immune signaling in brain leads to epigenetic modifications, alterations in synaptic plasticity, and loss of neuronal cell populations, which contribute to cognitive and emotive dysfunctions. Addiction involves progressive stages of drug binges and intoxication, withdrawal-negative affect, and ultimately compulsive drug use and abuse. Toll-like receptor signaling within cortical-limbic circuits is modified by alcohol and stress in a manner consistent with promoting progression through the stages of addiction

Systemic Glucose Administration Alters Water Diffusion and Microvascular Blood Flow in Mouse Hypothalamic Nuclei - An fMRI Study

© 2019 Lizarbe, Fernández-Pérez, Caz, Largo, Vallejo, López-Larrubia and Cerdán.The hypothalamus is the principal regulator of global energy balance, enclosing additionally essential neuronal centers for glucose-sensing and osmoregulation. Disturbances in these tightly regulated neuronal networks are thought to underlie the development of severe pandemic syndromes, including obesity and diabetes. In this work, we investigate in vivo the response of individual hypothalamic nuclei to the i.p. administration of glucose or vehicle solutions, using two groups of adult male C57BL6/J fasted mice and a combination of non-invasive T2∗-weighted and diffusion-weighted functional magnetic resonance imaging (fMRI) approaches. MRI parameters were assessed in both groups of animals before, during and in a post-stimulus phase, following the administration of glucose or vehicle solutions. Hypothalamic nuclei depicted different patterns of activation characterized by: (i) generalized glucose-induced increases of neuronal activation and perfusion-markers in the lateral hypothalamus, arcuate and dorsomedial nuclei, (ii) cellular shrinking events and decreases in microvascular blood flow in the dorsomedial, ventromedial and lateral hypothalamus, following the administration of vehicle solutions and (iii) increased neuronal activity markers and decreased microperfusion parameters in the ARC nuclei of vehicle-administered animals. Immunohistochemical studies performed after the post-stimulus phase confirmed the presence of c-Fos immunoreactive neurons in the arcuate nucleus (ARC) from both animal groups, with significantly higher numbers in the glucose-treated animals. Together, our results reveal that fMRI methods are able to detect in vivo diverse patterns of glucose or vehicle-induced effects in the different hypothalamic nuclei.This work was supported in part by grants SAF-2014-53739-R, SAF2017-83043-R, and S2017/BMD-3688 to SC and PL-L, and grant BFU2014-52149-R and BFU2017-89336-R to MV

Glass-coated ferromagnetic microwire-induced magnetic hyperthermia for in vitro cancer cell treatment

Limitations in effectiveness and the invasive nature of current cancer treatment options emphasize the need for further clinical advancements. Among other approaches, targeted hyperthermia is as a new strategy aimed at targeting cancerous cells to improve the efficacy of radiotherapy or cytotoxic drugs. However, the testing of magnetic vehicles has mainly focused on the use of nanoparticles. In this work, Fe77B10Si10C3 glass-coated amorphous magnetic microwires were assessed for the first time as magnetic vehicles with high potential for the localized heating of osteosarcoma cells by means of an AC magnetic field. The results from the in vitro assays performed inside a microfluidic device demonstrated the ability of these magnetic microwires to induce malignant cell death. Exposing the system to different magnetic fields for less than 1 h provoked a reduction up to 89% of the osteosarcoma cell population, whereas healthy myoblastoma cells remained nearly unaffected. The proposed technology demonstrates in vitro the effectiveness of these microwires as vehicles for targeted magnetic hyperthermia
