TL;DR: It is demonstrated that of all catheter-related interventions designed to prevent peritonitis in PD, only disconnect (twin-bag and Y-set) systems have been proved to be effective (compared with conventional spike systems).
Abstract: As many as 15 to 50% of end-stage kidney disease patients are on peritoneal dialysis (PD), but peritonitis limits its more widespread use. Several PD catheter-related interventions (catheter designs, surgical insertion approaches, and connection methods) have been purported to reduce the risk of peritonitis in PD. The goal was to assess the trial evidence supporting their use. The Cochrane CENTRAL Registry, MEDLINE, EMBASE, and reference lists were searched for randomized trials of catheter types and related interventions in PD. Two reviewers extracted data on the rates of peritonitis and exit-site/tunnel infection, catheter removal/replacement, technique failure, and all-cause mortality. Analysis was by a random effects model, and results are expressed as relative risk and 95% confidence intervals. Thirty-seven eligible trials (2822 patients) were identified: eight of surgical strategies of catheter insertion, eight of straight versus coiled catheters, 10 of Y-set versus conventional spike systems, four of Y-set versus double-bag systems, and seven of other interventions. Despite the large total number of patients, few trials covered the same interventions, small numbers of patients were enrolled in each trial, and the methodologic quality was suboptimal. Y-set and twin-bag systems were superior to conventional spike systems (seven trials, 485 patients; relative risk, 0.64; 95% confidence intervals 0.53 to 0.77), and no other catheter-related intervention was demonstrated to prevent peritonitis in PD. This systematic review demonstrates that of all catheter-related interventions designed to prevent peritonitis in PD, only disconnect (twin-bag and Y-set) systems have been proved to be effective (compared with conventional spike systems). Despite the importance of PD as a renal replacement therapy modality and the large number of patients who receive it, it is still not known whether any particular PD catheter designs, implantation techniques, or modalities are effective, given the limitations of available trials.

TL;DR: Uric acid-lowering therapy with allopurinol may retard the progression of CKD, and adequately powered randomized trials are required to evaluate the benefits and risks of uric acid- Lowering therapy in CKD.
Abstract: Background. Non-randomized studies suggest an association between serum uric acid levels and progression of chronic kidney disease (CKD). The aim of this systematic review is to summarize evidence from randomized controlled trials (RCTs) concerning the benefits and risks of uric acid-lowering therapy on renal outcomes. Methods. Medline, Excerpta Medical Database and Cochrane Central Register of Controlled Trials were searched with English language restriction for RCTs comparing the effect of uric acid-lowering therapy with placebo/no treatment on renal outcomes. Treatment effects were summarized using randomeffects meta-analysis. Results. Eight trials (476 participants) evaluating allopurinol treatment were eligible for inclusion. There was substantial heterogeneity in baseline kidney function, cause of CKD and duration of follow-up across these studies. In five trials, there was no significant difference in change in glomerular filtration rate from baseline between the allopurinol and control arms [mean difference (MD) 3.1 mL/min/1.73 m 2 , 95% confidence intervals (CI) −0.9, 7.1; heterogeneity χ 2 = 1.9, I 2 = 0%, P =

TL;DR: A theory of intergroup conflict and some preliminary data relating to the theory is presented in this article. But the analysis is limited to the case where the salient dimensions of the intergroup differentiation are those involving scarce resources.
Abstract: This chapter presents an outline of a theory of intergroup conflict and some preliminary data relating to the theory. Much of the work on the social psychology of intergroup relations has focused on patterns of individual prejudices and discrimination and on the motivational sequences of interpersonal interaction. The intensity of explicit intergroup conflicts of interests is closely related in human cultures to the degree of opprobrium attached to the notion of "renegade" or "traitor." The basic and highly reliable finding is that the trivial, ad hoc intergroup categorization leads to in-group favoritism and discrimination against the out-group. Many orthodox definitions of "social groups" are unduly restrictive when applied to the context of intergroup relations. The equation of social competition and intergroup conflict rests on the assumptions concerning an "ideal type" of social stratification in which the salient dimensions of intergroup differentiation are those involving scarce resources.
