    Abstract Artificial Intelligence (AI) is becoming more and more popular as time passes, allowing to perform tasks that were difficult to do in the past. From predictions to customization, AI is being used in many areas, not being educational environments outside this situation. AI is being used in educational settings to customize contents or to provide personalized feedback to the students, among others. In this scenario, AI in programming teaching is something that still has to be explored, since in this area we usually find assessment tools that allow grading the students work, but we can not find many tools aimed towards providing feedback to the students in the process of creating their program. In this work we present an AI based intelligent tutor that answers students programming questions. The tool has been tested by university students at the URJC along a whole course. Even if the tool is still in its preliminary phase, it helped the students with their questions, providing accurate answers and examples. The students were able to use the intelligent tutor easily and they thought that it could be a useful tool to use in other courses.

    Abstract Topic: Olfactory reference syndrome (ORS) is a psychiatric condition that is not known to many psychiatric providers and yet it is thought to be far more common than generally recognized. Symptoms of ORS are disruptive, debilitating, and can severely impair the daily functioning of patients dealing with it.
    Purpose: This article provides an overview of ORS and explores how it can be mistaken for other diagnostic constellations. A case report that details the treatment of a 14-year-old male illustrates how a clinician employs a multimodal approach to address symptoms that overlap with other diagnoses to successfully treat a patient with ORS.
    Sources: Existing literature on the treatment of ORS and obsessive-compulsive disorder in adults, adolescents, and children and the clinical experience of providing care to a 14-year-old patient in an outpatient setting.
    Conclusions: Nurses and other healthcare providers should be made more aware of the symptoms, criteria, and diagnosis of ORS. Research needs to be increased to solidify ORS as a formal diagnosis and treatment recommendations are required to better treat this underserved population.

    Abstract Purpose: The author explores the results of a 12-session therapy to address shame resilience as a mediator of empathy in the treatment of depression.
    Design and methods: Two instruments (the Beck Depression Inventory-II and the Test of Self-Conscious Awareness 3S) were used as pre-, mid-, and posttest measures given to a group (n = 20) in an intensive outpatient program receiving an intervention to increase shame resilience.
    Findings: A statistical decline in depressive symptoms at both mid- and posttest was noted.
    Practice implications: Adding shame resilience therapy to traditional psychotherapy may be useful to improve patient adherence and alliance but further evidence is needed.

    Abstract Background and objective: the use of 3D cameras for gait analysis has been highly questioned due to the low accuracy they have demonstrated in the past. The objective of the study presented in this paper is to improve the accuracy of the estimations made by robot-mounted 3D cameras in human gait analysis by applying a supervised learning stage.
    Methods: the 3D camera was mounted in a mobile robot to obtain a longer walking distance. This study shows an improvement in detection of kinematic gait signals and gait descriptors by post-processing the raw estimations of the camera using artificial neural networks trained with the data obtained from a certified Vicon system. To achieve this, 37 healthy participants were recruited and data of 207 gait sequences were collected using an Orbbec Astra 3D camera. There are two basic possible approaches for training and both have been studied in order to see which one achieves a better result. The artificial neural network can be trained either to obtain more accurate kinematic gait signals or to improve the gait descriptors obtained after initial processing. The former seeks to improve the waveforms of kinematic gait signals by reducing the error and increasing the correlation with respect to the Vicon system. The second is a more direct approach, focusing on training the artificial neural networks using gait descriptors directly.
    Results: the accuracy of the 3D camera to objectify human gait was measured before and after training. In both training approaches, a considerable improvement was observed. Kinematic gait signals showed lower errors and higher correlations with respect to the ground truth. The accuracy of the system to detect gait descriptors also showed a substantial improvement, mostly for kinematic descriptors rather than spatio-temporal. When comparing both training approaches, it was not possible to define which was the absolute best.
    Conclusions: supervised learning improves the accuracy of 3D cameras but the selection of the training approach will depend on the purpose of the study to be conducted. This study reveals the great potential of 3D cameras and encourages the research community to continue exploring their use in gait analysis.

    Abstract The eye is an immune privileged tissue that insulates the visual system from local and systemic immune provocation to preserve homeostatic functions of highly specialized retinal neural cells. If immune privilege is breached, immune stimuli will invade the eye and subsequently trigger acute inflammatory responses. Local resident microglia become active and release numerous immunological factors to protect the integrity of retinal neural cells. Although acute inflammatory responses are necessary to control and eradicate insults to the eye, chronic inflammation can cause retinal tissue damage and cell dysfunction, leading to ocular disease and vision loss. In this review, we summarized features of immune privilege in the retina and the key inflammatory responses, factors, and intracellular pathways activated when retinal immune privilege fails, as well as a highlight of the recent clinical and research advances in ocular immunity and ocular vascular diseases including retinopathy of prematurity, age-related macular degeneration, and diabetic retinopathy.

    Abstract Task-based programming models have risen in popularity as an alternative to traditional fork-join parallelism. They are better suited to write applications with irregular parallelism that can present load imbalance. However, these programming models suffer from overheads related to task creation, scheduling and dependency management, limiting performance and scalability when tasks become too small. At the same time, many HPC applications implement iterative methods or multi-step simulations that create the same directed acyclic graphs of tasks on each iteration. By giving application programmers a way to express that a specific loop is creating the same task pattern on each iteration, we can create a single task DAG once and transform it into a cyclic graph. This cyclic graph is then reused for successive iterations, minimizing task creation and dependency management overhead. This paper presents the taskiter, a new construct we propose for the OmpSs-2 and OpenMP programming models, allowing the use of directed cyclic task graphs (DCTG) to minimize runtime overheads. Moreover, we present a simple immediate successor locality-aware heuristic that minimizes task scheduling overhead by bypassing the runtime task scheduler. We evaluate the implementation of the taskiter and the immediate successor heuristic in 8 iterative benchmarks. Using small task granularities, we obtain an average speedup of 3.7x over the reference OmpSs-2 implementation and an average of 5x and 7.46x speedup over the LLVM and GCC OpenMP runtimes, respectively.

    Abstract The university environment is especially suitable for implementing health promotion interventions and specifically for physical activity promotion among university students. The objective of this systematic review was to describe the strategies employed and the physical activity data collection tools that have been used in said interventions. A systematic search for articles was conducted using the PubMED, Cochrane, and PEDro databases. The articles selected were those describing a physical activity promotion intervention aimed at university students in their own university setting in which there was a control group. Eventually, 1074 articles were identified, of which 13 fulfilled the selection criteria. The results show eight strategies and nine different instruments for collecting physical activity data. The strategies identified were used in combination and they were adapted in each of the complex interventions. Validated questionnaires were the most widely used instrument. Future original studies are needed to find out the impact of these strategies in physical activity promotion among university students specifically in the university context.

    Abstract This systematic review was carried out to compile and assess original studies that included economic evaluations of neurological physiotherapy interventions. A thorough search of PubMED, Cochrane and Embase was developed using keywords such as health economics, neurological physiotherapy and cost analysis, and studies published during the last six-year term were selected. A total of 3124 studies were analyzed, and 43 were eligible for inclusion. Among the studies analyzed, 48.8% were interventions for stroke patients, and 13.9% were focused on Parkinson's disease. In terms of the countries involved, 46.5% of the studies included were developed in the UK, and 13.9% were from the USA. The economic analysis most frequently used was cost-utility, implemented in 22 of the studies. A cost-effectiveness analysis was also developed in nine of those studies. The distribution of studies including an economic evaluation in this discipline showed a clear geographic dominance in terms of the pathology. A clear upward trend was noted in the economic evaluation of interventions developed in neurological physiotherapy. However, these studies should be promoted for their use in evidence-based clinical practice and decision-making.
