AIM To determine the incidence and associated factors of new-onset diabetes after transplantation(NODAT) in a Portuguese central hospital. METHODS This single-center retrospective study involved consecutive adult nondiabetic transplant recipients, who had undergone kidney transplantation between January 2012 and March 2016. NODAT was diagnosed according to the criteria of the American Diabetes Association. Data were collected from an institutional database of the Nephrology and Kidney Transplantation Department(Santa Maria Hospital, Lisbon, Portugal) and augmented with data of laboratorial parameters collected from the corresponding patient electronic medical records. Exclusion criteria were preexisting diabetes mellitus, missing information and follow-up period of less than 12 mo. Data on demographic and clinical characteristics as well as anthropometric and laboratorial parameters were also collected. Patients were divided into two groups: With and without NODAT-for statistical *** A total of 156 patients received kidney transplantduring the study period, 125 of who were included in our analysis. NODAT was identified in 27.2% of the patients(n = 34; 53% female; mean age: 49.5 ± 10.8 years; median follow-up: 36.4 ± 2.5 mo). The incidence in the first year was 24.8%. The median time to diagnosis was 3.68 ± 5.7 mo after transplantation, and 76.5% of the patients developed NODAT in the first 3 mo. In the group that did not develop NODAT(n = 91), 47% were female, with mean age of 46.4 ± 13.5 years and median follow-up of 35.5 ± 1.6 mo. In the NODAT group, the pretransplant fasting plasma glucose(FPG) levels were significantly higher [101(96.1-105.7) mg/d L vs 92(91.4-95.8) mg/d L, P = 0.007] and pretransplant impaired fasting glucose(IFG) was significantly more frequent(51.5% vs 27.7%, P = 0.01). Higher pretransplant FPG levels and pretransplant IFG were found to be predictive risk factors for NODAT development [odds ratio(OR): 1.059, P = 0.003; OR: 2.77

Evaluating the influences of fine-scale habitat heterogeneity on the composition,diversity,structure and functioning of forests is critical to understand how tropical forests will respond to climate change and devise forest management strategies that will enhance biodiversity conservation and aboveground biomass ***,we hypothesized that topographic and soil factors determine fine-scale habitat differentiation,which in turn shape community composition,species richness,structure and aboveground biomass at the local scale in tropical *** test this hypothesis,we selected two areas(each 100×100 m)with contrasting fine-scale topographic conditions where all trees,palms and lianas with a diameter at breast height ≥ 10 cm were tagged and identified to *** each selected area,100 subplots of 10×10 m were *** mainly found that higher topographic variability caused higher habitat differentiation with changes in species composition and community structure,but did not change species *** habitat-scale analyses indicated that,in the less heterogeneous area,the distribution of species was more uniform along a fine-scale topographical gradient with no variation in convexity,which induced changes in structure and aboveground biomass,but not in species *** nonsignificant relationship between species richness and aboveground biomass may be attributable to species redundancy or functional *** study suggests that environmental filtering is a fundamental process for shaping community assembly and forest functioning along a local topographical gradient in tropical forests.

BACKGROUND： Pulse wave analysis（PWA） quantifies the phenomenon of pulse waveform propagation in patients with cardiovascular diseases, whereas pulse image analysis（PIA） is a subjective examination in traditional Chinese medicine. OBJECTIVE： This study evaluated the association of PIA with PWA and hemodynamics in patients with hypertension. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： This observational, cross-sectional study enrolled 45 patients（26 men,（55.2± 10.3） years, systolic blood pressure（155± 28） mm Hg, diastolic blood pressure（93± 17） mm Hg） for assessment of clinical and laboratorial data. MAIN OUTCOME MEASURES： Primary outcomes comprised： pattern differentiation based on an automated method; PIA at the radial artery using the ‘simultaneous pressing＇ method for identification of factors such as strength（strong/weak）, depth（superficial/deep）, and speed（fast/moderate/slow）; and PWA at the same artery using a noninvasive system. RESULTS： Significant multivariate main effects were observed for depth（l=0.648, F_（5,29）=3.149, P=0.022, h^2 =0.352）, strength（l=0.608, F_（5,29） =3.736, P=0.010, h^2 =0.392）, and speed（l=0.535, F_（5,29） =5.302, P=0.002, h^2 =0.465）. General effects comprised high values of PWA and blood pressure for superficial, strong, and fast pulse images. A strong pulse was found for pulse pressure ≥ 62.5 mm Hg and systolic blood pressure ≥ 149.5 mm Hg, whereas a superficial pulse was found for heart rate ≥ 58.25 beats/min; a fast pulse was found for heart rate ≥ 69.6 beats/min and pulse wave velocity ≥ 9.185 m/s. CONCLUSION： Associations were explained by La Place＇s law, arterial remodeling in hypertension, alongside the traditional criterion for classifying speed in pulse images. PIA is associated with PWA and hemodynamics in patients with hypertension. Systolic and pulse pressures, heart rate, and pulse wave velocity are quantitative variables that have information to describe the qualitative pulse images such as strength, depth and speed.

This paper tries to characterize volcanic rocks through the development and application of an empirical geomechanical system. Geotechnical information was collected from the samples from several Atlantic Ocean islands including Madeira, Azores and Canarias archipelagos. An empirical rock classification system termed as the volcanic rock system(VRS) is developed and presented in detail. Results using the VRS are compared with those obtained using the traditional rock mass rating(RMR) system. Data mining(DM) techniques are applied to a database of volcanic rock geomechanical information from the *** algorithms were developed and consequently approaches were followed for predicting rock mass classes using the VRS and RMR classification systems. Finally, some conclusions are drawn with emphasis on the fact that a better performance was achieved using attributes from VRS.
