stiffness and pulse wave velocity / Aorta and carotid arteries 137 (0.94 to 1.01) p = 0.096; Obesity OR = 0.47 (0.29 to 1.77) p = 0.003 and Diabetes OR = 2.41 (1.15 -5.05) p = 0.020. Conclusions: According to the results obtained, genetic polymorphisms variables were not in the multivariate analysis equation to determine the increase of the PWV, which can be explained either by being included in the selected variables such as hypertension, or on the other hand, they may not have enough strength to remain in the equation. So, according to this study, PWV has much more to do with behaviors and traditional risk factors than the genetic heritage.P883 Endothelial dysfunction, pulse wave velocity and augmentation index are correlated in subjects with systemic arterial hypertension?

Scholarship on Christians in the Middle East has paid little attention to the role the Christian laity has played in defining and maintaining Christian identity and community boundaries. The so-called Orthodox issue (al-qaḍya al-urthudhuksiyya in Arabic) enhances our understanding of this role. It is an ongoing conflict within the Greek Orthodox Patriarchate of Jerusalem between the church leadership of Greek extraction and the Arab – usually lower-ranking – clergy and laity. This article uses a case-study approach to a series of protests in Jordan in 2014 against a decision by the Patriarchate to relocate a local reform-minded cleric. Using ethnographic, historical and philological methods, I argue that through their engagement in this struggle, Greek Orthodox Jordanians assert their identity as Christians, as Arabs and as loyal Jordanians. This offers a perspective into the complex interplay between church—community relations, the issue of pastoral care, and this community's identity.

Objectives: Robotic-assisted laparoscopic prostatectomy (RALP) is typically conducted in steep Trendelenburg position (STP). The aim of the study was to evaluate whether crystalloid administration and individual management of positive end-expiratory pressure (PEEP) improve peri- and post-operative pulmonary function in patients undergoing RALP. Design: Prospective randomised single-centre single-blinded explorative study. Setting: Patients were either allocated to a standard PEEP (5 cmH2O) group or an individualised high PEEP group. Furthermore, each group was divided into a liberal and a restrictive crystalloid group (8 vs. 4 mL/kg/h predicted body weight). Individualised PEEP levels were determined by means of preoperative recruitment manoeuvre and PEEP titration in STP. Participants: Informed consent was obtained from 98 patients scheduled for elective RALP. Interventions: The following intraoperative parameters were analysed in each of the four study groups: ventilation setting (peak inspiratory pressure [PIP], plateau pressure, driving pressure [Pdriv], lung compliance [LC] and mechanical power [MP]) and postoperative pulmonary function (bed-side spirometry). The spirometric parameters Tiffeneau index (FEV1/FVC ratio) and mean forced expiratory flow (FEF25–75) were measured pre- and post-operatively. Data are shown as mean ± standard deviation (SD), and groups were compared with ANOVA. A p-value of <0.05 was considered significant. Results: The two individualised high PEEP groups (mean PEEP 15.5 [±1.71 cmH2O]) showed intraoperative significantly higher PIP, plateau pressure and MP levels but significantly decreased Pdriv and increased LC. On the first and second postoperative day, patients with individualised high PEEP levels had a significantly higher mean Tiffeneau index and FEF25–75. Perioperative oxygenation and ventilation and postoperative spirometric parameters were not influenced by restrictive or liberal crystalloid infusion in either of the two respective PEEP groups. Conclusions: Individualised high PEEP levels (≥14 cmH2O) during RALP improved intraoperative blood oxygenation and resulted in more lung-protective ventilation. Furthermore, postoperative pulmonary function was improved for up to 48 h after surgery in the sum of the two individualised high PEEP groups. Restrictive crystalloid infusion during RALP seemed to have no effect on peri- and post-operative oxygenation and pulmonary function.
