Abstract
An 8-year-old boy presented with fever, vomits, bloody diarrhoea, and blurred vision. The patient was diagnosed with Haemolytic Uraemic Syndrome (HUS) due to the symptoms and a positive Verotoxin stool test. Funduscopic examination showed retinal involvement in both eyes, peri-papillary paleness, retinal haemorrhages, and soft "Purtscher Fleckens" exudates. A favourable outcome was achieved after hospital admission and systemic treatment. Dialysis treatment was not needed due the preserved diuresis. Although Purtscher-like retinopathy is very uncommon, ocular examination is mandatory in patients with pancreatitis, autoimmune diseases, and thrombotic microangiopathies, such as HUS.

Abstract
The application of statistics and mathematics over large amounts of data is providing healthcare systems with new tools for screening and managing multiple diseases. Nonetheless, these tools have many technical and clinical limitations as they are based on datasets with concrete characteristics. This proposition paper describes a novel architecture focused on providing a validation framework for discrimination and prediction models in the screening of Type 2 diabetes. For that, the architecture has been designed to gather different data sources under a common data structure and, furthermore, to be controlled by a centralized component (Orchestrator) in charge of directing the interaction flows among data sources, models and graphical user interfaces. This innovative approach aims to overcome the data-dependency of the models by providing a validation framework for the models as they are used within clinical settings.

Abstract
A major hurdle in eHealth implementation is that it is difficult to put into practice. In this study, the primary aim was to identify the main barrier associated with implementing eHealth. This study surveyed IMIA members from May to November 2015. From the results, it is clear that medical professionals were recording most of their data by hand. This paper culture is a paradigm that is difficult to break. Cultural factors are the primary barrier in eHealth implementation.

Abstract
Current trends in health management improvement demand the standardization of care protocols to achieve better quality and efficiency. The use of Clinical Pathways is an emerging solution for that problem. However, current Clinical Pathways are big manuals written in natural language and highly affected by human subjectivity. These problems make their deployment and dissemination extremely difficult in real practice environments. Furthermore, the intrinsic difficulties for the design of formal Clinical Pathways requires new specific design tools to help making them relly useful and cost-effective. Process Mining techniques can help to automatically infer processes definition from execution samples and, thus, support the automatization of the standardization and continuous control of healthcare processes. This way, they can become a relevant helping tool for clinical experts and healthcare systems for reducing variability in clinical practice and better understand the performance of the system.

Abstract
Determining the priority of attention in an Emergency Room (ER) has always been a difficult issue. Priority is determined with a simple triage system as people arrive at the hospital. It is important to establish how long they can wait for treatment. In order to obtain the best assessment of patients' conditions, we built a Nursing Software for Emergency Triage (NSET). The objective of this work was to assess the efficacy of the NSET versus the triage process without any software (TWS). Results showed that the NSET we built was a substantial help. With this software, we decreased significantly:1) the length of the triage system process, 2) the waiting time of patients in the waiting room, 3) the number of complaints and 4) the number of patients who walk away. In conclusion, the NSET improves and helps to define more accurately a patient's risk. NSET helps in the emergency department triage.

Abstract
INTRODUCTION Since 1996, when HAART became available, there has been a change in the course of HIV-infection, leading it to become a chronic disease. Our aim was to describe the characteristics of the children followed up in our hospital. PATIENTS AND METHODS A cross-sectional study was conducted on 32 HIV-infected children followed up until December-2010, at the University-Hospital de Getafe. Clinical and laboratory information from the last visit was collected for the evaluation of patients. RESULTS Thirty-two children with HIV-1 were evaluated, 29 infected through vertical-transmission. The median age was 14 years. According to the CDC classification, 56% (18/32) of children were in category A, 28% (9/32) B and 16% (5/32) C. Immunological class was 3 in 75% of children, class 2 in 9% and class 1 in 16%. The median nadir of CD4 was 337 cells/ml (12%). The median current CD4 was 749 (31%). Only one adolescent had a CD4% below 200 cells/ml due to lack of adherence. Twenty-eight patients (87%) were receiving HAART, and 4 patients were off antiretroviral treatment. Among the patients treated, 26 (93%) had viral loads <200 copies/ml. The median viral-load was<20 copies/ml. Median time on antiretroviral treatment was 10 years. The combination more frequently used was two nucleoside reverse transcriptase inhibitors (NRTI) and one protease inhibitor (PI), that was given to 15 patients (47%), followed by 2 NRTI, and one non-nucleoside reverse transcriptase inhibitor (NNRTI) in 8 patients (29%). Two children received rescue therapy including raltegravir, one with tipranavir and the other with darunavir. A total of 12 patients (43%) received medication once a day, 7 of them with fixed-dose combinations in a single tablet (25%). There were metabolic complications, including hyperlipidaemia or lipodystrophy were observed in 17 children (53%). CONCLUSIONS Most of our patients are receiving HAART, with good virological and immunological control. The prevalence of metabolic abnormalities was high. Strategies to improve adherence and decrease toxicities are needed in perinatally-acquired HIV-infected children.

Abstract
OBJECTIVES We undertook a prospective study to estimate the prevalence of gestational diabetes mellitus (GDM) and associated risk factors in a cohort of 669 HIV-1 infected women. METHODS The O'Sullivan and glucose tolerance tests were performed during regular visits of 609 mothers. RESULTS The median age of the cohort was 30.7 years (range 16-44), with most women having had heterosexual contact (67%). The majority were in Centers for Disease Control (CDC) category A (71%) and 53% exhibited hepatitis C co-infection. Median viral load and CD4 count at third trimester were 545 cells/microL (range 139-1690 cells/microL) and 1.9 log (range 1.7-5.4), respectively. Seventy-four per cent of the patients were treated with highly active antiretroviral therapy (HAART), of whom 41% received a protease inhibitor (PI). An above-average prevalence of 7% [95% confidence interval (CI) 5.2-9.5] for positive GDM diagnosis was found. Risk factors associated with GDM in univariate analysis included older age, hepatitis C co-infection, stavudine and PI exposure. However, only older age [adjusted odds ratio (AOR) 1.09, 95% CI 1-1.1] and PI exposure (AOR 2.4, 95% CI 1-5.3) remained as independent risk factors for GDM development in multivariate analysis. CONCLUSIONS In our cohort, the prevalence of GDM appears to be increased, with older age and PI exposure contributing as significant independent risk factors.

Abstract
A system based on mobile phones with built-in cameras has been developed for the postoperative management of patients sent home after day surgery. The system allows patients to send pictures and pulse oximetry measurements to a hospital server in a few seconds. Health professionals can then see what patients are describing and make a more objective estimate of the patients' status. Over a five-month period, a total of 49 patients used the system. A total of 222 images were sent, the average image delivery time being 29 s (SD 11). In nine cases (18%), the availability of images modified the treatment, and a visit to an emergency unit was avoided in eight of them who had blood-stained dressings and normal haematomas. The patients who had their treatment modified sent more images (an average of 5.4/patient) than those for whom images confirmed the correct treatment (3.1/patient). Each telephone call lasted for a mean duration of 18 min (range 8-34). The patient satisfaction data showed that all the aspects studied were evaluated in a very positive way, with 96% of the patients completely satisfied with the attention received by the mobile health application.

Abstract
In the Western World, cardiovascular diseases (CVD) are the leading source of death. Only in Europe, they cause 45% of all deaths. Besides heart failure, the paradigm of CVD, affects mainly people older than 65. Facing this reality, the European Union has funded MyHeart Project, whose mission is empowering citizens to fight CVD by means of a preventive lifestyle and an early diagnosis. This paper presents the design and development of the user interaction for a heart failure management system. This system consists on wearable and mobile technologies which monitors the vital body signals in a daily basis, providing a continuous assessment of this chronic disease.

Abstract
During a paleoparasitological survey of several animal mummies (Cavia aperea f. porcellus and Canis familiaris) from Chiribaya Baja, an archaeological site in Southern Peru, an unexpected find was made. In the well preserved fur, large numbers of mummified fleas (Pulex simulans/irritans) that parasitized the animals during life were encountered. Due to the relative recent event of the host mummification and the outstanding preservation of the fleas, an attempt for the retrieval of DNA was made. A DNA extraction and sequencing protocol for archaeological ectoparasitic remains has been established, taking additional studies for tissue and protein preservation into account. Tissue preservation was assessed with transmission electron microscopy and the protein preservation was tested through the racemisation ratios of aspartic acid. Regions of the 28S rDNA gene were successfully amplified and sequenced. Further research perspectives are outlined.

Abstract
Centralized testing demands costly laboratories, which are inefficient and may provide poor services. Recent advances make it feasible to move clinical testing nearer to patients and the requesting physicians, thus reducing the time to treatment. Internet technologies can be used to create a virtual laboratory information system in a distributed health-care environment. This allows clinical testing to be transferred to a cooperative scheme of several point-of-care testing (POCT) nodes. Two pilot virtual laboratories were established, one in Italy (AUSL Modena) and one in Greece (Athens Medical Centre). They were constructed on a three-layer model to allow both technical and clinical verification. Different POCT devices were connected. The pilot sites produced good preliminary results in relation to user acceptance, efficiency, convenience and costs. Decentralized laboratories can be expected to become cost-effective.
