UTCI field measurements in an urban park in Florence (Italy)

The aim of this study is to evaluate human thermal comfort in different green area settings in the city of Florence by using the Universal Thermal Climate Index (UTCI). Field measurements of air temperature, solar radiation, relative humidity, wind speed and black globe thermometer were collected during hot summer days in various parts of Cascine Park, the biggest urban park in Florence (Italy). UTCI was evaluated over different surfaces (asphalt, gravel and grass) completely exposed to the sun or shaded by a large lime tree (Tilia × europaea). The results showed strong differences in UTCI values depending on the exposure to tree shade, while no significant difference was found among ground-cover materials when all surfaces were equally exposed to solar radiation. Future studies are needed to investigate the microclimatic effects of different tree species on UTCI

Functional Tricuspid Regurgitation Repair at the time of Left-Sided Valve Surgery. the Impact on the Cardiac Rehabilitation Program

Objective: to compare the early post-operative functional status and the efficacy of the cardiac rehabilitation program (CRP) after isolated left-sided valvular surgery or with concomitant tricuspid valve repair (TVR). Methods: we retrospectively enrolled patients admitted to the Cardiac Rehabilitation Unit of our institution from January 2014 to January 2019, following mitral or aortic valve surgery. In agreement with current guidelines, concomitant tricuspid annuloplasty was added to patients with severe functional tricuspid regurgitation (TR) and in those with mild to moderate TR when annulus dilatation was present. A 6-minute walk test (6mWT) was performed within the second day of admission and repeated predischarge. The distances walked on the 6mWT were reported as absolute value and as a percentage of the predicted value, taking into account anthropometric variables. Changes in the 6mWT performance and Barthel index (BI) were assessed to evaluate the impact of CRP on exercise tolerance and functional independence, respectively. Results: of 117 patients, 62 (53%) had isolated left-sided valvular surgery and 55 (47%) had concomitant TVR. There were no significant differences between the two groups in the baseline 6mWT performance and its improvement at the end of CRP. TVR was associated with a worse BI on admission, but with a greater improvement after the CRP and a pre-discharge BI comparable to isolated left-sided surgery. Upon linear regression analysis, diabetes and chronic renal disease were predictors of the baseline 6mWT performance. Conclusion: TVR does not affect the early post-operative functional status and the efficacy of the CRP after valvular surgery

Emergency Department as an epidemiological observatory of Human Mobility: the experience of the Moroccan population

We conducted a retrospective study of the accesses to the Emergency Department registered from January 2000 to December 2014 in 5 major hospitals in the Metropolitan Area of Rome. We extrapolated data relating to patients of Moroccan origin from about 5 million total accesses, so we compared with Italians data which, in the same period, came to ED. The Moroccan population is distinguished by a larger number of diagnoses belonging to the ICD-9 code of Infectious Diseases and, more precisely, to Respiratory Infectious Diseases. There are also no differences in the assignment of such diagnoses to Moroccans with Italian citizenship, and this led to think that this could play an important role in the use of the ED and moreover that enrollment to the National Health Service may reduce its inappropriate use. Regarding to Degenerative Disorders, the result of our analysis is quite emblematic, showing that the accesses to the ED is due to Cardiovascular Diseases: 6.33% of Italians' accesses against 1.81% of Moroccans and 2.36% of Moroccans with Italian citizenship. The main explanation for this difference is, obviously, due to the age of the population: about 60% of Moroccans who accessed to ED was less than 40 years old. It is interesting how, in the field of ​​Cardiovascular Diseases, Moroccans have a lower percentage of diagnosis compared to Italians for acute diseases and a greater percentage of diagnoses for chronic diseases, suggesting once again that accesses to ED for migrants often is due to the inability to use the general services of the National Health Service. In conclusion, from the point of view of the Emergency Department, Migration Medicine still has Infectious Diseases as the main reason for access. Degenerative Disorders remain a prerogative of the Italians, but we could certainly assume that the Moroccan population would develop at some point with the aging

SEíS: Sistema basado en tecnologías semánticas para integrar la información energética de los edificios

Access to reliable energy related data is a fundamental factor when taking decisions that help to improve the energy efficiency of buildings. The increase in the amount of data we have available has led to the need to develop information systems that facilitate the analysis of such data to the agents which are present throughout the building life cycle, from the design phase to maintenance. Semantic web technologies provide a solution to interlink distributed data sources. This requires the construction of shared vocabularies (i.e. ontologies) which capture the meaning that users give to the data and facilitate access to them. As yet there are no consolidated methods to build these vocabularies. This article presents the methodology developed to create SEíS, an energy information system that uses semantic technologies to integrate energy related data and to facilitate services to the different agents involved throughout the stages of the building life cycle.El acceso a los datos relacionados con la energía es un factor fundamental para tomar decisiones que ayuden a mejorar la eficiencia energética de los edificios.

TEVAR for traumatic thoracic injury with the first-generation stent graft

Thoracic endovascular aortic repair (TEVAR) is a life-saving treatment for blunt thoracic aortic injury. We report long-term outcomes of two young patients who underwent TEVAR for blunt thoracic aortic injury with first-generation thoracic stent grafts. The off-label use of the endograft affected the outcomes: one case of open surgery conversion due to an aortoesophageal fistula and one case of endovascular relining for a voluminous pseudoaneurysm associated with a type III endoleak. Long-term follow-up is crucial in TEVAR, especially in case of a first-generation device used in an urgent setting

Development of Disposables and Accessories for ROSES and Their In Vitro Experimentation

This paper describes the development of the disposables and accessories for ROSES (Robotic System for Endovascular Surgery). Initially developed exclusively for transcatheter percutaneous coronary angioplasty, it was later modified, initially leaving the components for angioplasty substantially unchanged to extend its use to endovascular transcatheter surgery. These disposables are used to translate gear rotations into catheter or guide wire advancement or retraction and rotation of their body through friction wheels. The use of a new cart was necessary for endovascular surgery, to which a system to measure forces opposed by the patient’s body to catheter advancement was added. Moreover, since some endovascular catheters present with large diameters, minor mechanical modifications were also performed on the robot actuator (RA), previously defined as a slave, in order to allow large catheters to be pushed, such as those needed for the repair of some big aneurysms or for TAVI. However, in doing this, the possibility of separating the disposables into two components, upper and lower, was found, which allows the extraction of the disposable without having to remove the catheter or guide wire already positioned. Finally, the disposables, whose development is illustrated here, were subjected to various versions and tests and the results are reported
