Abstract
Background: The gap between offer and need for a kidney transplant (KT) has been increasing. The Kidney Donor Profile Index (KDPI) is a measure of organ quality and allows estimation of graft survival, but could not apply to all populations. Knowledge of our kidney donor and recipient population is vital to adjust transplant strategies. Methods: We performed a retrospective evaluation of donors and recipients of KT regarding two kidney transplant units: Centro Hospitalar Universitario de Coimbra, CHUC (Coimbra, Portugal) and Centro Hospitalar Universitario de Sao Joao, CHUSJ (Porto, Portugal), between 2013 and 2018. We then did statistical analysis and modeling, correlating these KT outcomes with donor and recipient characteristics, including KDPI. Artificial intelligence methods were performed to determine the best predictors of graft survival. Results: We analyzed a total of 808 kidney donors and 829 recipients of KT. The association between KDPI and graft dysfunction was only moderate. The decision tree machine learning algorithm proved to be better at predicting graft failure than artificial neural networks. Multinomial logistic regression revealed recipient age as an important prognostic factor for graft loss. Conclusions: In this Portuguese cohort, KDPI was not a good measure of KT survival, although it correlated with GFR 1 year post-transplant. The decision tree proved to be the best algorithm to predict graft failure. Age of the recipient was the most important predictor of graft dysfunction.

Abstract
The maintenance of plants in the increasing number of gardens and in the revegetation of degraded landscape areas generates a rising demand of water. However, shortage of water due to low and irregular rainfalls in semiarid zones such as the Mediterranean requires a rationalised use of water. In view of this, measure reducing water consumption such as minimum irrigation technique together with the use of native species with the ability to maintain its minimum ornamental value under stress watering conditions are essential for low water consumption. The aim of this work was to determine the minimum watering dosage in two native Mediterranean species (Santolina chamaecyparissus L. and Arbutus unedo L.) in order to maintain its ornamental value for their use in green areas. The assay was carried out in Northeast of Spain. Plants were distributed in Is independent plots sized 1.1 m(2). One third of the plants (6 plots) were not irrigated whereas the remaining two thirds received weekly through drip irrigation the quantity of water corresponding to 20% and 40% of the ETP0, respectively. During this study were regularly evaluated soil water content, atmospheric environmental conditions, survival rate, growth in height and surface (covering of the ground), intensity of the green colour and blossoming's intensity and longevity of Santolina chamaecyparissus L. flowers. Both species show significant difference in studied parameters between them. The 40% treatment compared to 0% treatment promoted significant differences in al studied parameters in Santolina chamaecyparissus L. and only in height and SPAD in Arbutus unedo L. The 20% irrigation treatment compared to the 0% treatment only promoted significant differences in SPAD of both species. The irrigation treatments also promoted that differences in growth rate started before than in non-irrigated treatment. From these results we can conclude that reduced water applications can improve ornamental value of xerigardening and landscaping plants under Mediterranean conditions.

Abstract
Typical chestnut thylakoid extracts isolated by mechanical disruption of leaf tissues had an equivalent of 0.28 g m(-3) chlorophyll (Chl) which is six times less than in thylakoids obtained from spinach, although Chl content in leaves was only half as small. According to optical microscopy, the vesicles showed a good integrity, exhibiting at 21 degrees C a high capacity of photon-induced potential membrane generation, which was demonstrated by the almost full 9-amino-6-chloro-2-methoxyacridine fluorescence quenching in a hyper-saline medium containing 150 mM KCl and having osmotic potential of -1.5 MPa. The half-time of the thylakoid potential generation was 11.7 s with the time of dissipation around 8.9 s. In such conditions, spinach thylakoids showed an increased swelling and also differences in the half-time generation which was almost four times faster than was observed in chestnut. However, when spinach thylakoids were incubated in a typical hypo-saline medium without KCl with osmotic potential -0.8 MPa, no additional swelling was observed. Consequently the half-time of potential dissipation was 35 s. Studies with nigericin suggested a chestnut thylakoid Delta pH significantly smaller than that observed in spinach, which was confirmed by the measurements of the ATP driven pumping activity.

Abstract
Diurnal and seasonal changes in the leaf water potential (T), stomatal conductance (g,), net CO2 assimilation rate (P-N), transpiration rate (E), internal CO2 concentration (Q), and intrinsic water use efficiency (P-N/g(s),) were studied in grapevines (Vitis vinifera L. cv. Touriga Nacional) growing in low, moderate, and severe summer stress at Vila Real (VR), Pinh (a) over tildeo (PI), and Almendra (AL) experimental sites, respectively. In VR and PI site the limitation to photosynthesis was caused more by stomatal limitations, while in AL mesophyll limitations were also responsible for the summer decline in P-N.

Abstract
Health care institutions need to implement rigorous clinical management systems. In this context, risk management has an important role aiming to minimize the likelihood of adverse events, thus contributing to improve the quality of provided health care. As the number and complexity of issues that must be addressed in hospitals is quite high and is increasing, it is essential the use of information systems to gather and monitor the hospital data. This paper proposes a new system to support the management of risk indicators, presenting the case of CHTMAD, a Portuguese hospital center. (C) 2012 Published by Elsevier Ltd.

Abstract
Objectives - This study aimed to identify: (i) the most relevant chronic diseases in terms of the application of technologies for ageing in place to promote the empowerment of patients; and (ii) types, outcomes and impacts of technologies for ageing in place being used to promote the empowerment of patients with chronic diseases. Methods - A systematic review of reviews and meta-analysis was performed based on a search of the literature. Results - A total of 34 reviews and meta-analysis across several chronic diseases were retrieved. These studies compare the empowerment of patients supported by different technologies with usual care. Conclusion - Technologies for ageing in place have positive effects on various health related outcomes, but further research is required to allow their incorporation in the clinical practice. © Springer International Publishing AG 2017.
