Background There is extensive concern about older people’s care in institutions, especially recently in the past years. One of the reasons is linked to the cases of elder abuse, not only shown by academic and scientific sources, but also by social and mass media and their impact on public perception of the institutional setting. What is more, current COVID-19 pandemic consequences on older people have provoked alarm and worry especially about what is happening in institutions. Methods The sample for this study consists of 286 staff working in nursing homes in Spain. This study aimed to assess the psychometric properties of the Professional Good Care Scale in Nursing Homes (GCS-NH). Results Results of parallel analyses and exploratory factor analyses (EFAs) showed a four-factor model for the 32-item scale: humanization (9 items), non-infantilization (10 items), respect (7 items) and empowerment (6 items). Then, psychometric properties were tested analysing internal consistency (reliability) and convergent, divergent and criterion validity. High internal consistency (reliability) and different validity evidence were obtained for the total scores of the GCS-NH and its subscales. GCS-NH scores were also capable of detecting risk of probable institutional elder abuse. Conclusions Results show that this scale is an appropriate, valid, and reliable multidimensional instrument to evaluate good care in older institutionalized people by staff. Good care is an outcome of a complex construct in which a wide range of factors converge (staff, older people, and environmental characteristics). The GCS-NH has potential to be used as a multidimensional tool to assess good care.

Memory and behavioral difficulties among older people living in nursing homes can cause burden and other consequences in professional caregivers. There is a lack of instruments that evaluate these behaviors and their influence in formal caregivers. The aim of this study is to develop and psychometrically test—the Revised Memory and Behavior Problems Checklist for Nursing Homes (RMBPC-NH). A cross-sectional study was carried out. The sample was made up of 312 formal caregivers working in nursing homes from different territories in Spain, 87.5% were women and 12.5% were men. The average age of participants was 39 years (SD = 12.2). The sample was recruited from January 2019 to March 2020. Participants completed a self-administered questionnaire, which included sociodemographic information, and assessed quality of technical equipment, level of training, experience of working with older people, job satisfaction, professional quality of life, burnout, and conception of negative stereotypes held towards aging. The four-factor structure of the RMBPC-NH showed a good fit, namely in relation to memory, functional, and emotional factors, and other problems. It has shown adequate psychometric properties, internal consistency, and validity (correlations with professional quality of life, job satisfaction, burnout, and negative stereotypes). The RMBPC-NH is a useful instrument to evaluate the frequency of older people’s memory and behavior problems and professional caregivers’ burden. The practical application in nursing homes is discussed

Researchers have mainly focused on aging risk factors and COVID19 consequences. However, older adults have proved their ability to overcome adversities along their life. Resilience is a protective variable that dampens the impact of stress. Based on MacLeod’s et al. (2016) approach, we aimed to analyze the relationship between older adults’ resilience and COVID19 relatedstressors as well as their physical, mental, and social characteristics. Eight hundred eightynine people aged 60 and over participated in this study. Older participants, women, having better perceived health and not losing a loved one because of the virus were associated with more resilience. Moreover, higher levels of gratitude, personal growth, life purpose and lower levels of depression were associated with greater scores in resilience. This study ofers a change of perspective in which aging is perceived from a positive viewpoint by focusing on easily accessible resources that may help older adults to cope with adverse situations.

Objectives: Caring for older adults is a demanding task. Some professionals may find themselves in complex situations for which they may not be prepared. However, the repercussions of these difficult experiences will depend on personal factors. Resilience acts as a buffer against difficulties and experiences. However, its study with first-line caregivers in nursing homes is limited. This study aimed to validate the Connor-Davidson Resilience Scale-2 (CD-RISC2), examine its psychometric properties, and analyze the variables associated with resilience (sociodemographic and professionals´ variables). Methods: 312 nursing home professionals participated in the study. Besides the Connor-Davidson Resilience Scale-2, they answered questionnaires about good care, burnout, quality of life, person-centered care, and well-being. Results: The CD-RISC2 showed adequate reliability and test-retest reliability. Good support was found for convergent validity with perceived health, person-directed care, personal growth, life purpose, quality of life and good care, and for discriminant validity with burnout. Conclusions: To our knowledge, this is the first study that validates the CD-RISC2 Spanish version with front-line workers in nursing homes showing adequate psychometric properties. Clinical implications: An abbreviated, simpler, self-assessed version may be more useful than longer versions, especially with professionals with a heavy workload, such as direct care staff in nursing homes.

Recent studies provide evidence that high-fat diets (HF) trigger both i) a deficit of reward responses linked to a decrease of mesolimbic dopaminergic activity, and ii) a disorganization of circadian feeding behavior that switch from a structured meal-based schedule to a continuous snacking, even during periods normally devoted to rest. This feeding pattern has been shown to be a cause of HF-induced overweight and obesity. Our hypothesis deals with the eventual link between the rewarding properties of food and the circadian distribution of meals. We have investigated the effect of circadian feeding pattern on reward circuits by means of the conditioned-place preference (CPP) paradigm and we have characterized the rewarding properties of natural (food) and artificial (cocaine) reinforcers both in free-feeding ad libitum HF mice and in HF animals submitted to a re-organized feeding schedule based on the standard feeding behavior displayed by mice feeding normal chow (“forced synchronization”). We demonstrate that i) ad libitum HF diet attenuates cocaine and food reward in the CPP protocol, and ii) forced synchronization of feeding prevents this reward deficit. Our study provides further evidence that the rewarding impact of food with low palatability is diminished in mice exposed to a high-fat diet and strongly suggest that the decreased sensitivity to chow as a positive reinforcer triggers a disorganized feeding pattern which might account for metabolic disorders leading to obesity.

The aim of this study was to comparatively study cyclin-dependent kinase 5 (CDK5) and c-Fos regulation by morphine in the brains of Lewis and Fischer 344 (F344) rats, which are known to differ in their behavioral sensitivities to several drugs of abuse. Two hours after an acute i.p. administration of morphine (10 mg kg(-1)) or saline (control), the animals were perfused and their brains prepared for immunohistochemistry. The number of CDK5 immunoreactive cells was significantly higher in the nucleus accumbens (NAC), the locus coeruleus (LC) and the nucleus tractus solitarius (NTS) of saline-injected F344 rats than in those of the Lewis rats. Morphine upregulated CDK5 with a varying pattern depending on the strain and brain area. The effect of the opioid was more marked in the NTS of the Lewis rats and the NAC of the F344 rats. Immunostaining of c-Fos was very low or absent in the control animals and was consistently up-regulated by morphine, especially in the LC and NTS of the F344 rats and the NAC of the Lewis rats. We propose that the acute morphine regulation of CDK5 expression in the NAC may predict the rate of drug intake and/or extinction of drug seeking, while the pattern of c-Fos activation may be more related to the differential acquisition of morphine-seeking behaviors

Introducción: El tratamiento con anticoagulantes orales derivados de cumarinas como el acenocumarol es bastante complejo pues, además de presentar un estrecho margen terapéutico, pueden interaccionar con numerosos fármacos, alimentos o productos de herbolario, favoreciendo la aparición de reacciones adversas y comprometiendo la seguridad del paciente anticoagulado. Objetivos: El objetivo de este trabajo ha sido evaluar la relación entre el grado de conocimiento del paciente en tratamiento con acenocumarol y la aparición de efectos adversos derivados del mismo. Métodos: Se realizó un estudio observacional descriptivo en 30 pacientes de 3 oficinas de farmacia y un centro de atención primaria de la Comunidad de Madrid. Para ello, se elaboró un cuestionario basado en el de Zeolla y cols. (2016), validado en EE.UU. para pacientes en tratamiento con warfarina y adaptado a nuestra zona geográfica y al tratamiento con acenocumarol. Resultados: Del 67% de los pacientes encuestados que afirmaron haber solicitado y obtenido consejo sobre el tratamiento con acenocumarol, sólo el 56% adquirió un grado de conocimiento adecuado y únicamente el 29% demostró conocer los medicamentos y productos de herbolario/dietéticos que debe evitar el paciente anticoagulado. Además, se observó que dicho grado de conocimiento era significativamente mayor en los pacientes que no habían presentado efectos adversos asociados al tratamiento anticoagulante con anterioridad. Conclusiones: Un adecuado grado de conocimiento acerca del tratamiento con acenocumarol y las posibles interacciones del mismo con otros medicamentos que no requieren prescripción médica o productos de herbolario/dietéticos reduce significativamente el riesgo de presentar efectos adversos asociados al tratamiento anticoagulante

La importancia creciente de los indicadores medioambientales, sostenibles y de gobernanza en el desempeño empresarial no solo impacta en su responsabilidad y transparencia, sino que también incide en los procedimientos concursales dirigidos a mantener o continuar las actividades empresariales viables, en particular, en las reestructuraciones preconcursales. La configuración del derecho preconcursal presenta características que ponen de manifiesto la conexión existente entre viabilidad, sostenibilidad y reestructuración. Las reestructuraciones deben aportar una perspectiva razonable de garantizar la viabilidad de la empresa, en el corto y medio plazo, y esta condición se ve abocada a acoger indicadores financieros, técnicos, comerciales y no financieros o de sostenibilidad.

The incorporation of plasma triglyceride (TG) fatty acids to white adipose tissue (WAT) depends on lipoprotein lipase (LPL), which is regulated by angiopoietin-like protein-4 (ANGPTL-4), an unfolding molecular chaperone that converts active LPL dimers into inactive monomers. The production of ANGPTL-4 is promoted by fasting and repressed by feeding. We hypothesized that the postprandial hormone cholecystokinin (CCK) facilitates the storage of dietary TG fatty acids in WAT by regulating the activity of the LPL/ANGPTL-4 axis and that it does so by acting directly on CCK receptors in adipocytes. We report that administration of CCK-8 (a bioactive fragment of CCK) to rats: (i) reduces plasma ANGTPL-4 levels; (ii) represses Angptl-4 expression in WAT and (iii) simultaneously enhances LPL activity in this tissue without inducing Lpl expression. In vivo CCK-8 effects are specifically antagonized by the CCK-2 receptor (CCK-2R) antagonist, L-365,260. Moreover, CCK-8 downregulates Angptl-4 expression in wild-type pre-adipocytes, an effect that is not observed in engineered pre-adipocytes lacking CCK-2R. These effects have functional consequences as CCK-8 was found to promote the uptake of dietary fatty acids by WAT, as demonstrated by means of proton nuclear magnetic resonance (1H-NMR). The efficacy of acute CCK-8 administration was not reduced after chronic CCK-8 treatment. Moreover, the effects of CCK-8 on WAT were not associated to the increase of circulating insulin. Our results show that cholecystokinin promotes lipid storage in WAT by acting on adipocyte CCK-2R, suggesting a pivotal role for CCK in TG homeostasis

Consumption of high-fat diets (HFD) has been associated with neuronal plasticity deficits and cognitive disorders linked to the alteration of glutamatergic disorders in the hippocampus. As young individuals are especially vulnerable to the effects of nutrients and xenobiotics on cognition, we studied the effect of chronic consumption of saturated (SOLF) and unsaturated oil-enriched foods (UOLF) on: i) spatial memory; ii) hippocampal synaptic transmission and plasticity; and iii) gene expression of glutamatergic receptors and hormone receptors in the hippocampus of adolescent and adult mice. Our results show that both SOLF and UOLF impair spatial short-term memory. Accordingly, hippocampal synaptic plasticity mechanisms underlying memory, and gene expression of NMDA receptor subunits are modulated by both diets. On the other hand, PPARγ gene expression is specifically down-regulated in adolescent SOLF individuals and up-regulated in adult UOLF mice.
