    Background: There is a high prevalence of musculoskeletal disorders among personnel working in the healthcare sector, mainly among nursing assistants and orderlies. Objective: The objective is to analyze the effectiveness of a multi-component intervention that included postural feedback in reducing musculoskeletal risk. Method: A total of 24 nursing assistants and orderlies in a hospital setting were randomly assigned to an intervention group or a control group. After collecting sociodemographic information, a selection of tasks was made and assessed using the REBA (rapid entire body assessment) method. A multi-component intervention was designed combining theoretical and practical training, including feedback on the postures performed by the professionals involved, especially those involving high musculoskeletal risk. This program was applied only to participants in the intervention group. Subsequently, eight months after the first assessment and intervention, the second assessment was carried out using the same method and process as in the first evaluation. Results: The results indicate that the musculoskeletal risk in the second assessment in the intervention group was significantly reduced. However, no significant changes were observed in the control group. Conclusion: The multi-component intervention applied can significantly reduce the musculoskeletal risk of nursing assistants and orderlies. In addition, it is a low-cost intervention with great applicability.Depto. de Psicología Social, del Trabajo y DiferencialFac. de PsicologíaTRUERegional Health Departmentpu

    Rapid identification of a range of hazardous airborne biological and chemical agents requires simultaneous detection at several specific wavelengths, and consequently a set of photodetectors with very narrow-band spectral responsivity. We demonstrate two ultraviolet photodetection configurations based on strained M-plane GaN films on LiAlO2(100) substrates grown by molecular-beam epitaxy with a detection bandwidth below 8 nm. The optical band gap of the film depends on the orientation of the linear polarization of the incident light relative to the c-axis of GaN, which lies in the film plane. The first configuration consists of a polarizationsensitive planar Schottky photodetector and a filter. An orthogonal alignment of the c-axis of the photodetector and the filter produces a detection system with a peak responsivity at 360 nm and a bandwidth of 6 nm. The second one consists of two planar Schottky photodetectors with their c-axes oriented perpendicular to each other. The difference signal between the two photodetectors produces a peak responsivity at 358 nm and a bandwidth of 7.3 nm

    Professionals working in a sanitary environment are often exposed to high emotional experiences that rise from the contact with vulnerability, loss, and suffering of patients and relatives, leading to a high exposition to stress.Advances in neurobiology and a higher knowledge of therapeutic relationships allow a better understanding of how we can look after ourselves better and provides resources to transform the experience of sufferers and companions.Understanding the role of self-awareness, presence and self-care and their neurobiological fundamentals allow the development of proposals to prevent the risk of burnout and other prevalent mental health problems among professionals.This work reviews the basis of help relationship, the risks and chances of our work, the relationship between empathy, self-awareness and compassion, as well as the emotional balance needed to work in this environment and self-awareness as a platform of presence and emotional regulation.Some useful practices for selfcare are presented, including teamwork as a protection factor. Finally, a commitment of professionals with their self-care is proposed.El trabajo en el entorno sanitario expone frecuentemente a los profesionales a experiencias de intensidad emocional, que emergen del contacto con la vulnerabilidad, las pérdidas y el sufrimiento de pacientes y familiares, lo que supone una elevada exposición al estrés. Los avances en neurobiología y la mejor comprensión de la neurofisiología de la relación terapéutica, permiten entender cómo podemos, no solo cuidarnos mejor, sino como dotarnos de recursos para transformar constructivamente la experiencia del que sufre y del que acompaña. La compresión del rol de la autoconciencia, la presencia y el autocuidado y sus fundamentos neurobiológicos, nos permiten elaborar propuestas para prevenir el riesgo de burn out y otros problemas de salud mental muy prevalentes entre los profesionales. El artículo revisa las bases de la relación de ayuda, los riesgos y oportunidades de nuestro trabajo, las relaciones entre empatía, autoconciencia y compasión; el balance emocional necesario para trabajar en este entorno y la autoconciencia como plataforma de la presencia y de la regulación emocional. Se ofrecen algunas prácticas útiles para el autocuidado, incluyendo el trabajo en equipo como factor de protección. Y finalmente se propone un compromiso del profesional con su autocuidado

    Background: The prevalence of Autism Spectrum Disorder (ASD) symptomatology is comparatively high in Cornelia de Lange Syndrome (CdLS). However, the profile and developmental trajectories of these ASD characteristics are potentially different to those observed in individuals with idiopathic ASD. In this study we examine the ASD profile in CdLS in comparison to a matched group of individuals with ASD.\ud \ud Method: The Autism Diagnostic Observation Schedule (ADOS) was administered to 20 individuals with CdLS (mean age = 11.34; range = 6yrs to 13yrs) and 20 individuals with idiopathic ASD (mean age = 10.42; range = 8yrs to 11yrs). Participants were matched according to adaptive behaviour skills and receptive language.\ud \ud Results: Sixty-five per cent (N= 13) of individuals with CdLS met the cut off score for autism on the total ADOS score. Further analysis at domain and item level indicated that individuals with CdLS showed significantly less repetitive behaviour, (specifically sensory interests); more eye contact, more gestures and less stereotyped speech than the ASD group. The CdLS group also showed higher levels of anxiety.\ud \ud Conclusions: The comparison between CdLS and idiopathic ASD indicates subtle group differences in the profile of ASD symptomatology that are not accounted for by degree of intellectual disability or receptive language skills. These differences may not be evident when relying solely upon clinical and domain level scores, but may be distinguishing features of the ASD presentations in the two disorders. The findings have implications for the conceptualisation and assessment of ASD in individuals with genetic syndromes

    Visual data mining with self-organizing maps for ''self-monitoring'' data analysis

    Data collected in psychological studies are mainly characterized by containing a large number of variables (multidimensional data sets). Analyzing multidimensional data can be a difficult task, especially if only classical approaches are used (hypothesis tests, analyses of variance, linear models, etc.). Regarding multidimensional models, visual techniques play an important role because they can show the relationships among variables in a data set. Parallel coordinates and Chernoff faces are good examples of this. This article presents self-organizing maps (SOM), a multivariate visual data mining technique used to provide global visualizations of all the data. This technique is presented as a tutorial with the aim of showing its capabilities, how it works, and how to interpret its results. Specifically, SOM analysis has been applied to analyze the data collected in a study on the efficacy of a cognitive and behavioral treatment (CBT) for childhood obesity. The objective of the CBT was to modify the eating habits and level of physical activity in a sample of children with overweight and obesity. Children were randomized into two treatment conditions: CBT traditional procedure (face-to-face sessions) and CBT supported by a web platform. In order to analyze their progress in the acquisition of healthier habits, self-register techniques were used to record dietary behavior and physical activity. In the traditional CBT condition, children completed the self-register using a paper-and-pencil procedure, while in the web platform condition, participants completed the self-register using an electronic personal digital assistant. Results showed the potential of SOM for analyzing the large amount of data necessary to study the acquisition of new habits in a childhood obesity treatment. Currently, the high prevalence of childhood obesity points to the need to develop strategies to manage a large number of data in order to design procedures adapted to personal characteristics and increase treatment efficacy

    Effects of Rose Hip (Rosa canina L.) Extract as a Natural Ingredient on the Nutritional Composition, Oxidative Stability and Sensory Attributes of Raw and Cooked Pork Patties from Majorcan Black Pig Breed under Retail Conditions

    This research evaluated the effect of rose hip (RC, Rosa Canina L.) extract as a natural antioxidant ingredient on the nutritional composition and sensory attributes of Majorcan Black Pig patties. Patties were elaborated with 1.5 and 3.0g of RC and with or without 0.03g of ascorbic acid. The results suggested that the patties with 15% fat (lower fat, higher α -tocopherol), would be healthier than the ones with 23% fat. The patties containing RC had similar amounts of vitamins C and E, which differed significantly from control. The results indicated that RC could reduce the patty lipid oxidation together with ascorbic acid and this could be a good alternative for food industry. The rose hip. Flavour did not show significant differences and its scores were low, suggesting that rose hip extract did not influence negatively the taste of the patties as well as their texture. However, future research is needed to test different concentrations of the extract.info:eu-repo/semantics/publishedVersio

    Structural basis for the inactivation of cytosolic DNA sensing by the vaccinia virus.

    Detection of cytosolic DNA is a central element of the innate immunity system against viral infection. The Ku heterodimer, a component of the NHEJ pathway of DNA repair in the nucleus, functions as DNA sensor that detects dsDNA of viruses that replicate in the cytoplasm. Vaccinia virus expresses two proteins, C4 and C16, that inactivate DNA sensing and enhance virulence. The structural basis for this is unknown. Here we determine the structure of the C16 - Ku complex using cryoEM. Ku binds dsDNA by a preformed ring but C16 sterically blocks this access route, abrogating binding to a dsDNA end and its insertion into DNA-PK, thereby averting signalling into the downstream innate immunity system. C4 replicates these activities using a domain with 54% identity to C16. Our results reveal how vaccinia virus subverts the capacity of Ku to recognize viral DNA
