[EX Q]: ♦', 'The quality of the peritoneal membrane can deteriorate over time. Exposure to glucose-based dialysis solutions is the most likely culprit. Because peritonitis is a common complication of peritoneal dialysis (PD), distinguishing between the effect of glucose exposure and a possible additive effect of peritonitis is difficult. The aim of the present study was to compare the time-course of peritoneal transport characteristics in patients without a single episode of peritonitis-representing the natural course-and in patients who experienced 1 or more episodes of peritonitis during long-term follow-up. ♦', 'This prospective, single-center cohort study enrolled incident adult PD patients who started PD during 1990-2010. A standard peritoneal permeability analysis was performed in the first year of PD treatment and was repeated every year. The results in patients without a single episode of peritonitis ("no-peritonitis group") were compared with the results obtained in patients who experienced 1 or more peritonitis episodes ("peritonitis group") during a follow-up of 4 years. ♦', 'The 124 patients analyzed included 54 in the no-peritonitis group and 70 in the peritonitis group. The time-course of small-solute transport was different in the groups, with the peritonitis group showing an earlier and more pronounced increase in the mass transfer area coefficient for creatinine (p = 0.07) and in glucose absorption (p = 0.048). In the no-peritonitis group, the net ultrafiltration rate (NUFR) and the transcapillary ultrafiltration rate (TCUFR) both showed a steep increase from the 1st to the 2nd year of PD that was absent in the peritonitis group. Both groups showed a decrease in the NUFR after year 3. A decrease in the TCUFR occurred only in the peritonitis group. That decrease was already present after the year 1 in patients with severe peritonitis. The time-course of free water transport showed a continuous increase in the patients without peritonitis, but a decrease in the patients who experienced peritonitis (p < 0.01). No difference was observed in the time-course of the effective lymphatic absorption rate. The time-courses of immunoglobulin G and α2-macroglobulin clearances showed a decrease in both patient groups, with a concomitant increase of the restriction coefficient. Those changes were not evidently influenced by peritonitis. The two groups showed a similar decrease in the mesothelial cell mass marker cancer antigen 125 during follow-up. ♦

[EX Q]: Covert hepatic encephalopathy (CHE) is associated with cognitive dysfunction, which affects daily function and health-related quality of life (HRQOL) in patients with cirrhosis. The effects of CHE and liver disease are determined by cognitive reserve—the ability of the brain to cope with increasing damage while continuing to function—and are assessed by composite intelligence quotient (IQ) scores. We examined cognitive reserve as a determinant of HRQOL in patients with cirrhosis.', 'We performed a prospective study of 118 outpatients with cirrhosis without overt HE (age, 56 y). We studied cognition using the standard paper-pencil battery; patients with below-normal results for more than 2 tests were considered to have CHE. We also assessed HRQOL (using the sickness impact profile [SIP]), psychosocial and physical scores (a high score indicates reduced HRQOL), model for end-stage liver disease (MELD) scores, and cognitive reserve (using the Barona Index, a validated IQ analysis, based on age, race, education, residence area, and occupation). Cognitive reserve was divided into average and high groups (<109 or >109), and MELD and SIP scores were compared. We performed regression analyses, using total SIP score and psychosocial and physical dimensions as outcomes, with cognitive reserve, CHE, and MELD score as predictors.', 'Study participants had average MELD scores of 9, and 14 years of education; 81% were white, 63% were urban residents, their mean IQ was 108 ± 8, and 54% had average cognitive reserve (the remaining 46% had high reserves). CHE was diagnosed in 49% of patients. Cognitive reserve was lower in patients with CHE (109) than without (105; P = .02). Cognitive reserve correlated with total SIP and psychosocial score (both r = -0.4; P < .001) and physical score (r = -0.3; P = .01), but not MELD score (P = .8). Patients with high cognitive reserve had a better HRQOL, despite similar MELD scores. In regression analyses, cognitive reserve was a significant predictor of total SIP (P < .001), psychosocial (P < .001), and physical scores (P < .03), independent of CHE, MELD, or psychiatric disorders.

[EX Q]: It was recently reported that protein disulfide isomerase (PDI) stimulates factor X (FX) activation by factor VIIa (FVIIa) bound to soluble tissue factor (sTF) in a purified system and that PDI may be responsible for activating cellular tissue factor (TF) and switching it between its roles in blood coagulation and cellular signalling. This study further investigates the former effect of PDI.', 'FX activations by FVIIa-sTF(1-219) were carried out in the presence of different forms of PDI, with annexin V or detergent present in the system and using various forms of FVIIa and FX. In addition, FVIIa-lipidated TF was used as the FX activator.', 'Recombinant human PDI did not influence FX activation by FVIIa-sTF(1-219), whereas PDI purified from bovine liver enhanced the activation rate in a dose-dependent manner. The inclusion of annexin V or detergent abolished the stimulatory effect. Removal of the phospholipid-interactive gamma-carboxyglutamic acid (Gla)-containing domain from either FVIIa or FX obliterated the bovine PDI-induced enhancement of FX activation, as did the introduction of F4A or L8A mutation in FVIIa. The presence of 25 nM bovine PDI lowered the apparent K(m) for FX from far above 10 microM to 1-2 microM. No PDI effect was seen when FVIIa-lipidated TF was the FX activator.
