[EX Q]: Morbidly obese patients usually present vitamin D deficiency or secondary hyperparathyroidism. Low vitamin D levels have been recently related to non-alcoholic fatty liver disease (NAFLD). The aim of this study was to analyse the relationship between vitamin D, bone turnover markers and non-alcoholic fatty liver disease and metabolic syndrome in severely obese patients.', 'One hundred and ten patients who underwent bariatric surgery were included. Liver biopsy was taken during surgery. Two univariate analyses were carried out in order to i) analyse the relationship between liver histology and vitamin D-bone turnover markers (intact parathyroid hormone (PTH), osteocalcin and Carboxy-terminal collagen crosslinks) and ii) establish the association between metabolic syndrome components-insulin resistance (HOMA) and vitamin D-bone turnover markers.', '70% of the patients had lower levels of vitamin D or secondary hyperparathyroidism. None of the components of liver histology were associated with levels of vitamin D or with bone turnover parameters. Patients with metabolic syndrome showed lower levels of PTH and osteocalcin (72,42 (29,47) vs 61.25(19.59) p-Value: 0.022; 19.79 (10.43) vs 16.87(10.25) p-Value: 0,028, respectively). HOMA was not related to Vitamin D or bone turnover markers.

[EX Q]: Thromboembolic events represent a clinically significant cause of neurological morbidity during the endovascular management of cerebral aneurysms. We have implemented an anti-thromboembolic regimen consisting of pre- and postoperative dual antiplatelet therapy, as well as postoperative anticoagulation using heparin and dextran. The aims of our study were to examine the effect of this regimen on thromboembolic rates during elective aneurysm coiling, and to elucidate risk factors associated with the development of thromboembolic events in this setting.', 'We conducted a retrospective review of patients who underwent elective intracranial aneurysm coiling between January 2005 and February 2012. The primary outcome of interest was the occurrence of a clinically significant peri-procedural thromboembolic event. Secondary outcomes included the occurrence of a central nervous system (CNS) or systemic hemorrhage.', 'During the study period, 312 patients underwent elective aneurysm coiling and six (2%) thromboembolic events occurred; three (1%) occurred in the group that received the anti-thromboembolic regimen (261 patients) and three (6%) occurred in the group that did not receive the regimen (51 patients), resulting in a statistically significant difference (P=0.024). Both the presence of a hypercoagulable state (P=0.014) and the lack of the anti-thromboembolic regimen (P=0.043) were significantly associated with the occurrence of a thromboembolic event.

[EX Q]: Preservation of mucosal immunity has been shown to affect the risk and outcome of pneumonia in severely injured patients. Secretory immunoglobulin A (SIgA) is the principle humoral defense of mucosal surfaces in the body and has several antiinflammatory properties. Polymorphonuclear neutrophils (PMN) function to kill invading microorganisms, but their exaggerated inflammatory responses may cause tissue injury to the host. The purpose of this study was to compare the ability of different immunoglobulin (Ig) isotypes to modulate PMN cytotoxic potential cocultured with respiratory epithelial cells challenged with bacteria.', 'Calu-3 cell monolayers were established on membranes (0.1-microm pore) in a two-chamber culture system. Escherichia coli (EC) incubated with either polyclonal SIgA or IgG was inoculated into the apical chamber and PMNs (10/mL) added to the basal chamber. PMN cytotoxic potential was indexed by % CD11b expression, superoxide anion (O2) production, and elastase release. Dextran flux was used to index Calu-3 monolayer permeability.', 'Addition of EC to PMN-Calu-3 cell coculture increased % CD11b expression, O2 production, and elastase release. IgG had no effect on PMN activation after EC challenge. SIgA abrogated PMN activation and the increase in Calu-3 cell monolayer permeability noted with EC or EC + IgG treatment groups.
