Background: Prediction of complications after pancreatoduodenectomy (PD) remains of interest. Blood parameters and biomarkers during rst and second postoperative days (POD1, POD2) may be early indi- cators of complications. Methods: This case-control study included 50 patients. Baseline, POD1 and POD2 values of leukocytes, neutrophils, lymphocytes, platelets, hemoglobin, C-reactive protein (CRP), procalcitonin and arterial lactate were compared between individuals presenting Clavien ≥ III morbidity, pancreatic stula (PF) or clinically relevant PF (CRPF) and those without these morbidities. Common variables reaching signi cance were further analyzed in order to calculate a predictive score. Results: Severe morbidity, PF and CRPF rates were 28.0%, 26.0% and 14.0%, respectively. Patients with severe morbidity had lower leukocytes on POD2 (P=0.04). Patients with PF presented higher CRP on POD2 (P=0.001), higher lactate on POD1 (P=0.007) and POD2 (P=0.008), and lower lymphocytes on POD1 (P=0.007) and POD2 (P=0.008). Patients with CRPF had lower leukocytes and neutrophils on POD1 (P =0.048, P =0.038), lower lymphocytes on POD1 (P =0.001) and POD2 (P =0.003), and higher CRP on POD2 (P =0.001). Baseline parameters and procalcitonin obtained no statistical associations. Score was de ned according to lymphocytes on POD1 < 650/μL and CRP on POD2 ≥ 250 mg/L allocating patients in 3 risk categories. PF and CRPF rates were statistically higher as risk category increased (P<0.001). Receiver operating characteristic curves and Hosmer Lemeshow tests showed a good accuracy. Conclusions: Impaired immunological reaction during early postoperative period (lower leukocytes and, particularly, lymphocytes) in response to surgical aggression would favor complications after PD. Likewise, acidosis (higher arterial lactate) could behave as risk factor of PF. An elevated CRP on POD2 is also an early biomarker of PF. Our novel score based on postoperative lymphocyte count and CRP seems reliable

The severe and rapid attack on the Caicos pine Pinus caribaea var. bahamensis(Pinaceae) by the nonnative invasive pine tortoise scale, Toumeyella parvicornis, has resulted in the death of most of the trees in the Turks and Caicos Islands(TCI) in just over a decade. Local and international conservation efforts have enabled the necessary multi-disciplinary research, data gathering, and monitoring to develop and implement a restoration strategy for this endemic tree from the Bahaman archipelago. The native plant nursery established on North Caicos and horticultural expertise acquired throughout the years were crucial to the successful rescue of Caicos pine saplings from the wild populations and cultivation of new saplings grown from locally sourced seeds. These saplings have been used to establish six Restoration Trial Plots on Pine Cay and a seed orchard on North Caicos in TCI. Core Conservation Areas(CCAs) for the Caicos pine forests have been identified and mapped. To date, forest within the Pine Cay CCA has been supplemented by planting more than 450 pine trees, which have survived at a high(>80%)rate.

Background: Major morbidity in pancreatic surgery remains high. Different scores for predicting complications have been described. Preoperative pancreatic resection(PREPARE) score is based on objective preoperative variables and offers good predictive accuracy for Clavien ≥ III complications. This study aimed to validate this score and analyze other preoperative variables in a prospective study performed in a medium-volume center. Methods: A total of 50 pancreatic resections were included. Preoperative variables were registered and PREPARE was calculated. The main outcome was severe morbidity(Clavien ≥ III) up to 30 days after discharge. The secondary outcomes were length of stay(LOS) and readmission. Statistical validation was performed to compare severe morbidity rate among the scores categories. Association with other preoperative variables(not included in PREPARE) was also tested. Results: Of the 50 pancreatic resections, the severe morbidity was 34.0%, with median LOS of 11 days. Readmission rate was 25.5%. Severe morbidity rates according to PREPARE categories were 18.5% in lowrisk group, 41.7% in intermediate-risk group, and 63.6% in high-risk group, respectively( P = 0.023). The accuracy was 72%(Hosmer–Lemeshow, P = 0.86). ROC curve was obtained both for PREPARE score expressed as incremental values and categorized as the three risk groups, showing an area under curve(AUC) of 0.736(95% CI: 0.586–0.887; P = 0.007) and 0.712(95% CI: 0.555–0.869; P = 0.015), respectively. PREPARE was significant in multivariate analysis. Median LOS was statistically higher as PREPARE category increases(9, 11 and 15 days in low-, intermediate-and high-risk groups, respectively; P = 0.009). Readmission was not associated with any variables. Conclusions: PREPARE behaves as an independent risk factor for severe morbidity after pancreatic surgery. Score validation shows good accuracy prediction. Increasing PREPARE category is also associated with longer LOS.

Two methodologies to rank exploitation scenarios for hydrocarbon fields during screening and concept selection stages are described and compared. First a selection based on net present value valuation is introduced and an explanation on its limitations for field planning are given thus, a second selection based on a multiattribute decision model where other technical factors not directly associated to economics such as operability and reliability are considered. A comparison of net present value and the multiattribute decision model on a concept selection study case shows differences on the scenario selection for exploitation. Sources of the different outcomes between the two methodologies are identified. A stochastic analysis for the multiattribute decision model is performed to have a complete view of the possible outcomes since the factors in the multiattribute decision model are measured qualitatively and their values can vary depending on experts’ knowledge and experience. Recommendations obtained from the methodologies studied for screening and concept selection are given.

Dear Editor Abscisic acid （ABA） is the main phytohormone involved in adaptive crop responses to drought. ABA signaling relies on the family of pyrabactin resistance 1/PYRl-like/regulatory components of ABA receptors （PYR/PYL/RCAR）, which upon ABA binding form high-affinity ternary complexes with clade A protein phosphatases type 2C （PP2Cs） and inhibit them （Cutler et al., 2010）. This results in the activation of an SnRK2-dependent phosphorylation cascade affecting a high number of targets in the plant cells, regulating stomatal aper- ture and the expression of stress-responsive genes （Cutler et al., 2010）.
