Effect on blood lipids and body composition of a high-fat (MUFA) and high-fiber diet: A case-control study.

Metabolic Syndrome (MetS) is a constellation of risk factors including abdominal obesity, high triglycerides, low HDL cholesterol (HDL-C), elevated blood pressure, and elevated fasting glucose. In Spain, according to WHO criteria, the MetS prevalence is shown to be 32% in men and 29% in women. The role of dietary habits is one of the main therapeutic strategies for the management of MetS but the most effective dietary pattern has not been established yet. This study aimed to analyze the effect of on body composition, serum lipids, and MetS components of a high-MUFA and high-fiber diet (HMFD). A case-control study was performed considering 40 cohabiting women. Participants were randomly assigned to HMFD group or high mono-unsaturated diet (HMD) group to receive one of the two proposed dietary interventions. All data (serum lipids, blood pressure, height, weight, body composition, and waist circumference) were collected fasting at baseline, 55, 98, and 132 days. The HMFD group showed higher decrease in waist circumference than in the HMD group. LDL-C dropped in both groups. Triglycerides in the HMFD group dropped during the intervention, but once the intervention was over, they returned to baseline values. The mean systolic blood pressure was lower in HMFD group. A HMFD from a weekly consumption of processed meat (Torrezno de Soria) deeply fried in extra virgin olive oil in combination with vegetables logged in a Mediterranean diet can improve MetS risk factors in healthy overweight women.

Assessment of nurses' level of knowledge of the management of chronic wounds.

BACKGROUND: Chronic wounds are a challenge and a major cause of morbidity. A wound is considered chronic if healing does not occur within the expected time frame depending on the etiology and location of the wound. OBJECTIVE: To assess the level of knowledge about chronic wound management of postgraduate nurses in different areas of the health system and their previous satisfaction with the training received during their undergraduate studies. DESIGN: Cross-sectional study of a health system of 95,000 inhabitants and 557 nursing professionals working in it. PARTICIPANTS: Nurses working in the study health system and in areas with care for patients with chronic wounds in social, primary and hospital care. RESULTS: Survey results described a low knowledge of chronic wound management in general. Data on knowledge according to area of work showed that nurses in primary care had the highest knowledge of wound etiology. Nurses working in health and social care were most knowledgeable in diagnostic knowledge. Hospital nurses showed the lowest knowledge overall. A relationship was observed when nurses had a master's degree followed by an expert with better knowledge in the test. In addition, nurses reported little training in chronic wounds during their university studies (69.73 %, n = 106). CONCLUSIONS: Therefore, a review of this point should be considered to improve the management of chronic wounds and their correct approach among nursing students. A review of continuing and even specialised training needs in the clinical care setting should also be considered.

Prognostic Significance of Amino Acid and Biogenic Amines Profiling in Chronic Kidney Disease.

There is a pressing need for more precise biomarkers of chronic kidney disease (CKD). Plasma samples from 820 subjects [231 with CKD, 325 with end-stage kidney disease (ESKD) and 264 controls] were analyzed by liquid chromatography with tandem mass spectrometry (LC-MS/MS) to determine a metabolic profile of 28 amino acids (AAs) and biogenic amines to test their value as markers of CKD risk and progression. The kynurenine/tryptophan ratio showed the strongest correlation with estimated glomerular filtration rate values (coefficient = -0.731, p < 0.0001). Models created with orthogonal partial least squares-discriminant analysis (OPLS-DA) containing the metabolic signature showed a high goodness of fit and predictability for controls/CKD (R2X:0.73:R2Y:0.92:Q2:0.92, p < 0.0001) and lower values for CKD/ESKD (R2X:0.56:R2Y:0.59:Q2:0.55, p < 0.0001). Based on generated VIP scores, the most relevant markers for segregating samples into control/CKD and CKD/ESKD groups were citrulline (1.63) and tryptophan (1.47), respectively. ROC analysis showed that the addition of the metabolic profile to a model including CKD classic risk factors improved the AUC from 86.7% (83.6-89.9) to 100% (100-100) for CKD risk (p < 0.0001) and from 63.0% (58.2-67.8) to 96.5% (95.3-97.8) for the risk of progression from CKD to ESKD (p < 0.0001). Plasma concentrations of AAs and related amines may be useful as diagnostic biomarkers of kidney disease, both for CKD risk and for progression of CKD patients to ESKD.

Hydroxychloroquine safety in Covid-19 vs non-Covid-19 patients: analysis of differences and potential interactions.

BACKGROUND: The use of hydroxychloroquine (HCQ) in the first COVID-19 epidemic wave raised safety concerns. RESEARCH DESIGN AND METHODS: Adverse reactions (ADR) suspected to be induced by HCQ and submitted to the Spanish Pharmacovigilance Database were studied. A disproportionality analysis was performed to determine adverse effects reported in non-Covid and Covid patients. To explore potential drug-drug interactions, Omega (Ω) statistics was calculated. RESULTS: More severe cases were reported when used in COVID-19. Main differences in frequency were observed in hepatobiliary, skin, gastrointestinal, eye, nervous system and heart ADRs. During the COVID-19 pandemic, high disproportionality in reports was found for Torsade de Pointes/QT prolongation with a ROR (-ROR) of 132.8 (76.7); severe hepatotoxicity, 18.7 (14.7); dyslipidaemias, 12.1 (6.1); shock, 9.5 (6.9) and ischemic colitis, 8.9 (2.6). Myopathies, hemolytic disorders and suicidal behavior increased their disproportionality during the pandemic. Disproportionality was observed for neoplasms, hematopoietic cytopaenias and interstitial lung disease in the pre-COVID-19 period. Potential interactions were showed between HCQ and azithromycin, ceftriaxone, lopinavir and tocilizumab. CONCLUSIONS: The use of HCQ during the Covid-19 pandemic changed its ADRs reporting profile. Of particular concern during the pandemic were arrhythmias, hepatotoxicity, severe skin reactions and suicide, but not ocular disorders. Some signals identified would require more detailed analyses.

Effects of Antioxidants on Pain Perception in Patients with Fibromyalgia-A Systematic Review.

In recent years, antioxidant supplements have become popular to counteract the effects of oxidative stress in fibromyalgia and one of its most distressing symptoms, pain. The aim of this systematic review was to summarize the effects of antioxidant supplementation on pain levels perceived by patients diagnosed with fibromyalgia. The words used respected the medical search terms related to our objective including antioxidants, fibromyalgia, pain, and supplementation. Seventeen relevant articles were identified within Medline (PubMed), Scopus, Web of Science (WOS), the Cochrane Database of Systematic Review, and the Cochrane Central Register of Controlled Trials. This review found that antioxidant supplementation is efficient in reducing pain in nine of the studies reviewed. Studies with a duration of supplementation of at least 6 weeks showed a benefit on pain perception in 80% of the patients included in these studies. The benefits shown by vitamins and coenzyme Q10 are remarkable. Further research is needed to identify the effects of other types of antioxidants, such as extra virgin olive oil and turmeric. More homogeneous interventions in terms of antioxidant doses administered and duration would allow the effects on pain to be addressed more comprehensively.

Physical Condition and Risk of Hospitalization and Polypharmacy in Older Adults.

Hospitalization in older population leads to a decline in physical function, physical condition, and independency. However, a scarce number of studies has addressed the effect of being in good physical condition on the risk of hospitalization and polypharmacy in older people. Therefore, this study aims to examine the relationship between physical condition and other health factors, and the incidence of hospitalization and polypharmacy in Spanish older persons. For this cross-sectional study we recruited 102 institutionalized persons aged 80 years or older, who were being treated at three primary care centers. The data collected were number of hospitalizations and medications, dietary habits, nutrition status, quality of life, independence in activities of daily life, physical performance, and associated genotype data. Scoring higher in the tests Chair stand and 8-Foot Up-and-go was found associated with reduced risks of hospitalization (odds ratio [OR] = 0.45 [95% CI = 0.2-0.99]; OR 0.32 [95% CI = 0.12-0.86]) and polypharmacy (OR = 0.36 [95% CI = 0.16-0.8]; OR = 0.28 [95% CI = 0.1-0.78]). The number of medications was also lower in individuals with a greater aerobic capacity and activities of daily life independence (OR = 0.28 [95% CI = 0.1-0.78]; OR = 0.37 [95% CI = 0.16-0.82]). No associations were found with the remaining physical performance tests or other factors assessed. Our findings point to benefits of greater strength, balance, and aerobic capacity in terms of reducing the risk of hospitalization and polypharmacy.

Haplotypes in the GC, CYP2R1 and CYP24A1 Genes and Biomarkers of Bone Mineral Metabolism in Older Adults.

Candidate gene studies have analyzed the effect of specific vitamin D pathway genes on vitamin D availability; however, it is not clear whether genetic variants also affect overall bone metabolism. This study evaluated the association between genetic polymorphisms in GC, CYP2R1 and CYP24A1 and serum levels of total 25(OH)D, iPTH and other mineral metabolism biomarkers (albumin, total calcium and phosphorus) in a sample of 273 older Spanish adults. We observed a significant difference between CYP2R1 rs10741657 codominant model and total 25(OH)D levels after adjusting them by gender (p = 0.024). In addition, the two SNPs in the GC gene (rs4588 and rs2282679) were identified significantly associated with iPTH and creatinine serum levels. In the case of phosphorus, we observed an association with GC SNPs in dominant model. We found a relationship between haplotype 2 and 25(OH)D levels, haplotype 4 and iPTH serum levels and haplotype 7 and phosphorus levels. In conclusion, genetic variants in CYP2R1 and GC could be predictive of 25(OH)D and iPTH serum levels, respectively, in older Caucasian adults. The current study confirmed the role of iPTH as one of the most sensitive biomarkers of vitamin D activity in vivo.

Impact of an intervention program with reinforcement on nursing students' stress and anxiety levels in their clinical practices.

BACKGROUND AND OBJECTIVE: Several interventions have resulted in effectively reducing stress and anxiety in nursing students, however the efficacy of these interventions has only been investigated in the short term. This study had to objectives 1) to determine the effect of an intervention program to manage stress and anxiety in nursing students during clinical practices with two phases, phase I composed by cognitive behavioral therapy and progressive muscle relaxation and phase II or reinforcement phase with progressive muscle relaxation and 2) to determine the effect of phase I of the intervention program to manage stress and anxiety in nursing students during clinical practices. DESIGN: An experimental, analytical, longitudinal and prospective study. METHODS: Data were collected between April 2018 to June 2019 with 4 measurements of KEZKAK questionnaire and State-Trait Anxiety Inventory. An intervention program composed of cognitive behavioral therapy and progressive muscle relaxation was developed. The intervention program was divided in two phases, phase I and phase II or reinforcement phase. Fifty-nine nursing students from a Spanish university participated. A control group (n = 29), an intervention group one (n = 15) that received phase I and an intervention group 2 (n = 15) that received phase I and phase II or reinforcement phase were formed. RESULTS: After completing phase I, significant differences were found in the state of stress and anxiety between nursing students who received this phase and those who did not and after 3 months they continued to show differences. After phase II or reinforcement phase, the inter-groups did not present significant differences between them. The inter-group comparison of the stress and anxiety values at the end of the intervention program minus the initial values indicated that the CG presented significant differences with both intervention groups in the total of the KEZKAK and also with the IG1 in factors 3 (p = 0.030) and 4 (p = 0.027) and with the IG2 in factors 1 (p = 0.006) and 7 (p = 0.018). On the other hand, no differences were found between both intervention groups, IG1-IG2, in levels of stress and anxiety (p > 0.05) CONCLUSIONS: The intervention program contributes to provide evidence on the effectiveness of cognitive behavioral therapy and progressive muscle relaxation for stress and anxiety management in nursing students during clinical practices. This study suggests that we should continue in this line of research to improve the available evidence.

Does the Addition of Pain Neurophysiology Education to a Therapeutic Exercise Program Improve Physical Function in Women with Fibromyalgia Syndrome? Secondary Analysis of a Randomized Controlled Trial.

Therapeutic exercise (TE) is one of the most investigated approaches for the management of FMS. Pain neurophysiology education (PNE) helps toward understanding the pain condition, leading to maladaptive pain cognitions and coping strategies in patients with chronic pain. Our study aimed to assess the effects of therapeutic exercise and pain neurophysiology education versus TE in isolation on fatigue, sleep disturbances, and physical function in the short term and at three months of follow-up in women with fibromyalgia syndrome (FMS). A single-blind randomized controlled trial was carried out. A total of 32 women with FMS referred from medical doctors and fibromyalgia association were randomized in 2 groups: PNE + TE group or TE group. Fatigue and sleep disturbances (Visual Analog Score) and physical function (Senior Fitness Test) were assessed before, after intervention, and at three months of follow-up. Significant improvements were achieved in the Timed Up and Go test (p = 0.042) and Arm Curl test (p = 0.043) after intervention and on handgrip in the non-dominant side at three months of follow-up (p = 0.036) on the PNE + TE group. No between-groups differences were found for fatigue, sleep disturbances, and the rest of test included in the Senior Fitness Test. In conclusion, these results suggest that PNE + TE appears to be more effective than TE in isolation for the improvement of physical function (Timed Up and Go test and Arm Curl test) in women with FMS in the short term.

Muscular Strength and Quality of Life in Older Adults: The Role of ACTN3 R577X Polymorphism.

As longevity is increasing, the 65-year-old and older population is projected to increase in the next decades, as are the consequences of age-related muscle deterioration on the quality of life. The purpose of this study was to examine the associations of the ACTN3R577X polymorphism with quality of life and muscular strength in an older Spanish population. In total, 281 older adults participated in this study. Anthropometric measurements, chronic diseases, prescribed medications, quality of life, hand grip strength, and physical activity and nutritional status data were collected. ACTN3 R577X genotyping was determined using Taqman probes. Multivariate regression analysis revealed in adjusted model that, in men, the ACTN3 R577X genotype was significantly associated with hand grip strength (HGS), regression coefficient (ß) = 1.23, p = 0.008, dimension 1 of the five-dimension questionnaire EuroQoL (EQ-5D, mobility), (ß) = -1.44, p = 0.006, and clinical group risk (CGR) category (ß) = -1.38, p = 0.006. In women, a marginal association between the ACTN3 R577X genotype and the CGR category was observed, with a regression coefficient of (ß) = -0.97, (p = 0.024). Our findings suggest that the ACTN3 R577X genotype may influence the decline in muscle strength and quality of life in older Spanish adult males.

Therapeutic Exercise and Pain Neurophysiology Education in Female Patients with Fibromyalgia Syndrome: A Feasibility Study.

BACKGROUND: We compared the effects of therapeutic exercise (TE) combined with pain neurophysiology education (PNE) to those of TE in isolation on pain intensity, general fibromyalgia impact, mechanical pain sensitivity, pain catastrophizing, psychological distress and quality of life in women with fibromyalgia syndrome (FMS). METHODS: A feasibility study with a 3 month follow-up was designed. Thirty-two patients with FMS were randomly assigned to PNE + TE group (n = 16) or to TE group (n = 16). Both groups received 30 sessions of TE (3 per week), and the PNE + TE group received eight face-to-face educational sessions. The measuring instruments used were the visual analogue scale, a standard pressure algometer, the Revised Fibromyalgia Impact Questionnaire, the Pain Catastrophizing Scale, the Hospital Anxiety and Depression Scale and the Health Assessment Questionnaire. RESULTS: The PNE + TE group showed a statistically significant decrease on pain intensity compared to TE group at short term (p = 0.015). No between-groups differences were found for mechanical pain sensitivity, general fibromyalgia impact, pain catastrophizing, psychological distress or quality of life (p > 0.05). CONCLUSIONS: The combination of PNE and TE was more effective than TE for reducing pain intensity in the short-term. No differences were found for psychological distress, pain catastrophizing and quality of life after the intervention or at 3 months of follow-up.

OBJETIVO: describir la percepción del estrés, los factores potencialmente estresantes y la ansiedad de los estudiantes de la Facultad de Enfermería de Soria al comienzo de sus prácticas clínicas, y determinar la influencia de factores sociodemográficos, académicos, situación familiar y estilos de vida sobre la percepción de estos. MÉTODO: estudio descriptivo transversal con 61 estudiantes de la Facultad de Enfermería de Soria (curso). Se estudiaron variables sociodemográficas (sexo, edad, actividad laboral), académicas (año de ingreso, cursar solo Prácticum I, beca, otros estudios), de situación familiar (residencia, pareja, personas a cargo, familiar sanitario, pérdida de familiar), estilos de vida (fumador/a, bebedor/a, ejercicio físico), estrés y factores potencialmente estresores (Cuestionario KEZKAK -mín. 0 a máx. 3 puntos-) y ansiedad estado-rasgo (Cuestionario STAI -mín. 0 a máx. 60 puntos-). Se realizaron análisis descriptivo y bivariantes para las variables psicológicas. RESULTADOS: participaron 60 estudiantes (edad mediana (Me) = 21 años). La puntuación global de estrés presentó una mediana de 1,89 (RIQ = 0,48). Los factores percibidos como más estresantes fueron "falta de competencia" (Me = 2,09; RIQ = 0,43) e "impotencia e incertidumbre" (Me = 2,05; RIQ = 0,54). La ansiedad estado-rasgo presentó una mediana de 17 (IQR = 8) y 17,5 (IQR = 10), respectivamente. El nivel de estrés, los factores potencialmente estresantes y la ansiedad estado se asociaron con el sexo (p < 0,05). CONCLUSIONES: los estudiantes de Enfermería en sus primeras prácticas clínicas percibieron niveles de estrés moderadamente altos y una ansiedad moderada, siendo los principales estresores "falta de competencia" e "impotencia e incertidumbre". El sexo está altamente asociado con el estrés y la ansiedad, siendo mayor en las mujeres

OBJECTIVE: to describe the perception of stress, the potentially stressful factors, and the anxiety among students from the School of Nursing of Soria at the start of their clinical practice; and to determine the impact on their perception of sociodemographical and academic factors, their family situation and lifestyles. METHOD: a descriptive cross-sectional study with 61 students from the School of Nursing of Soria (course). The study included sociodemographical variables (gender, age, occupation), academic (year of admission, practicum I only, scholarship, other studies), family situation (place of residence, partner, dependent persons, health professional relatives, loss of relatives), lifestyles (smoking, drinking, physical exercise), stress and potential stressors (KEZKAK Questionnaire -min. 0 to max. 3 scores-) and State-Trait anxiety (STAI Questionnaire -min. 0 to max. 60 scores). Descriptive and bivariate analyses were conducted for the psychological variables. RESULTS: the study included 60 students (median age (Me= 21-year-old). The overall stress score presented a median score of 1.89 (IQR = 0.48). The factors perceived as more stressful were "lack of competence" (Me = 2.09; IQR = 0.43) and "impotence and uncertainty" (Me = 2.05; IQR = 0.54). The State-Trait anxiety presented a median score of 17 (IQR = 8) and 17.5 (IQR = 10), respectively. The level of stress, potential stressors and state anxiety were associated with gender (p< 0.05). CONCLUSIONS: nursing students in their first clinical practice perceived moderately high levels of stress and moderate anxiety; the main stressors were "lack of competence" and "anxiety and uncertainty". Gender is highly associated with stress and anxiety, and it is higher in women

Mishel's Model of Uncertainty Describing Categories and Subcategories in Fibromyalgia Patients, a Scoping Review.

The aim of this review was to demonstrate the presence of categories and subcategories of Mishel's model in the experiences of patients with fibromyalgia by reviewing qualitative studies. Uncertainty is defined as the inability to determine the meaning of disease-related events. A scoping review of qualitative studies was carried out. Twenty articles were included, with sample sizes ranging from 3 to 58 patients. Articles from different countries and continents were included. Three categories of the model and eight subcategories could be shown to be present in the experiences of fibromyalgia patients through the scoping review. The first category, concerning antecedents of uncertainty in patients with fibromyalgia, is constituted by the difficulty in coping with symptoms, uncertainty about the diagnosis and uncertainty about the complexity of the treatment. The second concerns the cognitive process of anxiety, stress, emotional disorder and social stigma. The third category refers to coping with the disease, through the management of social and family support and the relationship with health care professionals.

Physical Performance and Quality of Life in Older Adults: Is There Any Association between Them and Potential Drug Interactions in Polymedicated Octogenarians.

Older adults are at increased risk of several cytochrome P450 (CYP) drug interactions that can result in drug toxicity, reduced pharmacological effect, and adverse drug reactions. This study aimed to assess the prevalence of potential CYP interactions referring to the most clinically relevant drugs and exploring the relationship between them and quality of life and physical performance in Spanish octogenarians. Institutionalized and community-dwelling octogenarians (n = 102) treated at three primary care centers, were recruited by a research nurse. Anthropometric measurements, chronic diseases, prescribed drugs, quality of life, physical performance, mobility skills, hand grip strength and cognitive status data were collected. Potential CYP drug-drug interactions (DDIs) were selected referring to the main CYP implicated in their metabolism. The 72.2% of recruited octogenarians presented potentially inappropriate CYP inhibitor-substrate or CYP inductor-substrate combinations. Analyzing the EuroQol Visual Analogue scale (EQ-VAS) results, patients with a potential CYP DDI perceived worse health status than patients without it (p = 0.004). In addition, patients with a potential CYP DDI presented worse exercise capacity, kinesthetic abilities, or mobility than those who didn't present a potential interaction (p = 0.01, p = 0.047, and p = 0.02, respectively). To investigate and control factors associated with loss of muscle strength and poor quality of life, polypharmacy and DDIs could help institutions in the management of physical frailty.

The antioxidants in the process of ocular pathology / Los antioxidantes en el proceso de patologías oculares

Introduction: The influence of antioxidants on ocular processes has taken on a significant importance in recent years for its effects on visual health. Oxidative stress is a factor involved in the development of major pathologies such as cataracts, glaucoma and age-related macular degeneration (AMD). Objective: To establish the scientific evidence that exists about the different types of antioxidants and their effects on ocular pathological processes through a systematic review. Methods: Literature search in MEDLINE, Scielo and Cochrane for studies evaluating the use of antioxidants in the prevention and/or treatment of eye diseases. Selected randomized controlled clinical trials over the past 7 years were selected. Results: The relationship between different types of antioxidants, vitamin E, C, beta carotene, zinc, lutein, anthocyanins and carotenoids, suggests a positive relationship with the risk and progression of AMD and glaucoma parameters, indicating a lower risk of the disease due to an increased consumption of antioxidants in the diet. Initial reports suggest a potential role for diet modification in the treatment of age-related macular degeneration and glaucoma primarily, not evidencing for the prevention of cataract. Conclusions: Promoting adequate consumption of antioxidants in the diet can prevent and protect against highly prevalent eye diseases. The antioxidants of the group of vitamins are the most studied so far in the ocular pathologies. More clinical trials are needed to establish these relationships more precisely.

Introducción: la influencia de los antioxidantes en los procesos oculares ha tomado en los últimos años una relevancia importante por sus efectos en la salud visual. El estrés oxidativo es un factor implicado en el desarrollo de las principales patologías tales como cataratas, glaucoma y degeneración macular asociada a la edad (DMAE). Objetivo: establecer la evidencia científica que existe sobre los distintos tipos de antioxidantes y sus efectos en procesos patológicos oculares mediante una revisión sistemática. Métodos: búsqueda bibliográfica en MEDLINE, Scielo y Cochrane de estudios que evalúan la utilización de antioxidantes en la prevención y/o tratamiento de las enfermedades oculares. Se seleccionaron ensayos clínicos controlados y aleatorizados publicados en los últimos 7 años. Resultados: la relación entre distintos tipos de antioxidantes, vitamina E, C, betacaroteno, zinc, luteína, antocianinas y carotenoides, sugiere una relación positiva ante el riesgo y progresión de DMAE y parámetros del glaucoma, indicando un menor riesgo de la enfermedad ante un mayor consumo de antioxidantes en la dieta. Informes iniciales sugieren un papel potencial para la modificación de la dieta en el tratamiento de la degeneración macular asociada a la edad y glaucoma principalmente, no evidenciándose para la prevención de la catarata. Conclusiones: promover el consumo adecuado de antioxidantes en la dieta puede prevenir y proteger frente a patologías oculares de gran prevalencia. Los antioxidantes del grupo de vitaminas son los más estudiados hasta el momento en las patologías oculares. Es necesario llevar a cabo más ensayos clínicos para establecer de forma más precisa estas relaciones.

Aplicación de la Hermenéutica Analógica al análisis de los modelos de enseñanza universitaria de enfermería / Analogical hermeneutic´s application to the analysis of teaching university models of nursing

En los últimos años se han producido cambios sociales que afectan a los profesionales de la educación. Estos cambios pueden poner en riesgo su calidad de vida profesional, personal y, por tanto, la calidad del sistema educativo. Esto nos lleva a estudiar qué le sucede al profesor. En este estudio centramos nuestra investigación en el docente universitario en ciencias de la salud. Para ello, mediante el análisis hermenéutico, basado en el triángulo actor-texto-lector, analizamos tres de los modelos conceptuales existentes en los docentes españoles: modelo presagio-proceso-producto, modelo mediacional y modelo personal. Tras este análisis concluimos que el modelo personal, a nuestro juicio, es el más adecuado para evaluar y analizar procesos existenciales, experimentales y vivenciales de la educación. Este modelo es el que nos aporta una mayor posibilidad hermenéutica, ya que es un modelo multidimensional y centra su interés en los elementos ontológicos y experienciales del proceso

There have been social changes affecting education professionals last years. These changes can reduce professional efficacy, personal accomplishment and therefore the quality education system. This leads us to study what happens to the professor. In this study we focused our research on university teacher in health sciences. We analyze three conceptual models: presage-process-product model, mediational model and personal model through a hermeneutical analyze based on actor-test-lector. We suggest the personal model to evaluate and analyze the existential, experimental and experientials processes of education. This one gives us a higher hermeneutical possibility since that it is a multidimensional model and it interest is focused on the ontological and experiential elements of the process

Calidad de vida profesional de enfermería en urgencias de un hospital de referencia / Professional quality of life of nurse in a hospital emergency unit reference

Objetivo: El objetivo de este estudio fue medir la Calidad de Vida Profesional de los enfermeros en la unidad de urgencias de un hospital en su puesto de trabajo, a través de tres dimensiones: motivación intrínseca, apoyo directivo y cargas de trabajo. La mayoría de estudios sobre calidad de vida a nivel mundial se hacen principalmente en colectivos de enseñanza y también los profesionales de la salud, sufren desgaste profesional, según estudios diversos. Si queremos mejorar la calidad de los cuidados prestados, debemos empezar conociendo cómo percibe el profesional de Enfermería dicha calidad de vida, así como si existen o no factores que la condicionen. Métodos: Estudio descriptivo transversal con análisis correlacional. El presente estudió investigó la calidad de vida profesional de los enfermeros de una Unidad de Urgencias de un Hospital público español. Fue llevado a cabo entre Marzo y Mayo de 2014. Para ello se utilizó el 'cuestionario CVP-35'. Resultados: La tasa de respuesta fue alta. Los enfermeros percibieron una baja calidad de vida profesional. La calidad de vida profesional se correlaciona con el Apoyo directivo y la Motivación intrínseca, aunque no se asocia con la Carga de Trabajo. La edad es la variable sociodemográfica que influye en cómo perciben su calidad de vida profesional los enfermeros de urgencias. Conclusión: En relación con otros estudios, si mejoramos el Apoyo directivo, la percepción de la calidad de vida profesional de los profesionales de enfermería que trabajan en urgencias aumentaría (AU)

Objective: The objective of this study was to measure the quality of professional life of nurses in their workplace in the emergency unit of a Hospital, through three dimensions intrinsic motivation, support and management workloads. Most studies on quality of life worldwide are made primarily in teaching groups and health professionals. According to various studies, this group is very likely to suffer burnout. If we improve the quality of care provided, we must start knowing how nursing professionals perceive quality of life, as well as whether there are constraining factors involved. Methods: Cross-sectional study survey of nurses working in an Emergency Unit of a Spanish public hospital. It was conducted between March and May of 2014. The sample consisted on 60 subjects. Data were collected using the CVP-35 questionnaire. Results: The response rate was high. The nurses perceived low quality of professional life. The professional quality of life correlates with management support and intrinsic motivation, although no association with the workload was found. Age is the demographic variable that influences how they perceive their quality of working life emergency nurses. Conclusion: Compared to other studies, if we improve the management support, perception of the quality of working life of nurses working in emergency increase (AU)
