Effects of a Novel Peritoneal Dialysis: The Open Versus Laparoscopic Preperitoneal Tunneling Technique
Authors: Bircan Huseyin Yuce , Kulah Eyyup 
Published: December 2015

AbstractThe key to achieving adequate continuous ambulatory peritoneal dialysis (CAPD) is that a functioning catheter should enable unrestricted inflow and outflow of the dialysate liquid from the peritoneal cavity with an intact peritoneal membrane. Despite its advantages, complications, such as outflow obstruction, catheter‐related infection, and dialysate leakage are still problematic. Various laparoscopic techniques for catheter placement have been investigated. The main purpose of this study was to compare the laparoscopic and open surgical peritoneal dialysis (PD) catheter insertion techniques in a retrospective manner according to catheter survival, complications and the safety of both techniques. The study included end stage renal disease patients in our hospital in whom a PD catheter was placed between 2007 and 2014. Patients were divided into two groups: the open technique (OT) group and the laparoscopic preperitoneal tunneling approach (LA) group. Extracted data included patient demographics, operative data, catheter‐related complications and follow‐up data. Sixty‐nine patients were enrolled into the study. CAPD catheters were placed into 35 patients via LA and 34 via OT. We found that the LA group patients had better survival rates compared with the OT group, especially the long‐term survivals. All of the CAPD‐related complications, (peritonitis, malposition, outflow obstruction, leakage) were lower in the LA group. However, the peritonitis, malposition and groin hernia rates were also statistically significantly lower in the LA group. When compared with the published data, we recommend laparoscopic CAPD catheter placement with a preperitoneal tunneling technique. The technique is safe and offers a better outcome.

AbstractAimsTo estimate (1) the associations between parent–adolescent relationship, parental knowledge and subsequent adolescent drinking frequency and (2) the influence of alcohol use on parental knowledge.DesignPath analysis of school based cohort study with annual surveys.SettingPost‐primary schools from urban and intermediate/rural areas in Northern Ireland.ParticipantsA total of 4937 post‐primary school students aged approximately 11 years in 2000 followed until approximately age 16 years in 2005.MeasurementsPupil‐reported measures of: frequency of alcohol use; parent–child relationship quality; subdimensions of parental monitoring: parental control, parental solicitation, child disclosure and child secrecy.FindingsHigher levels of parental control [ordinal logistic odds ratio (OR) = 0.86, 95% confidence interval (CI) = 0.78, 0.95] and lower levels of child secrecy (OR = 0.83, 95% CI = 0.75, 0.92) were associated subsequently with less frequent alcohol use. Parental solicitation and parent–child relationship quality were not associated with drinking frequency. Weekly alcohol drinking was associated with higher subsequent secrecy (beta −0.42, 95% CI = –0.53, −0.32) and lower parental control (beta −0.15, 95% CI = –0.26, −0.04). Secrecy was more strongly predictive of alcohol use at younger compared with older ages (P = 0.02), and alcohol use was associated less strongly with parental control among families with poorer relationships (P = 0.04).ConclusionsAdolescent alcohol use appears to increase as parental control decreases and child secrecy increases. Greater parental control is associated with less frequent adolescent drinking subsequently, while parent–child attachment and parental solicitation have little influence on alcohol use.

AbstractBackground and AimsDespite ambiguous evidence for the effectiveness of alcohol screening with brief interventions (BI) in emergency departments (ED), ambition for their widespread implementation continues to grow. To clarify whether such an application of BI is justifiable, we conducted a systematic review and meta‐analysis on studies testing the impact of BI on alcohol consumption.MethodsWe included peer‐reviewed, randomized controlled studies investigating the effects of BI on alcohol consumption in injured and/or intoxicated patients, published January 2002–September 2015. Changes from baseline in consumption quantity, intensity and number of heavy drinking episodes were assessed at 3‐, 6‐ and 12‐month follow‐up, resulting in nine separate random‐effects meta‐analyses of standardized mean differences (SMD). Moderation effects of intervention mode, length, type of interventionist, intensity of control intervention and study quality were assessed using subgroup comparisons and meta‐regression.ResultsWe considered 33 publications (28 separate studies) including 14 456 patients. Six of nine comparisons revealed small significant effects in favour of BI, with the highest SMD at 0.19 [95% confidence interval (CI) = 0.08–0.31]. No significant moderators could be identified, and statistical heterogeneity (I2) was below 40%.ConclusionsIn a large meta‐analysis of randomized controlled trials in emergency care settings, there was evidence for very small effects of brief interventions on alcohol consumption reductions. More intensive interventions showed no benefit over shorter approaches. Non‐face‐to‐face interventions appear to be comparably effective, but this finding remains tentative due to the low number of non‐face‐to‐face studies.

BackgroundUncontrolled studies in human have suggested that memantine might be a suitable option for migraine prophylaxis.ObjectiveTo assess the efficacy and tolerability of memantine for migraine prophylaxis.MethodsThis was a 12‐week randomized double‐blind placebo‐controlled parallel‐group study. Sixty patients with migraine without aura were randomized using a computer‐generated list to receive memantine (10 mg/day) or placebo for 12 weeks. The primary outcome was the difference in change from baseline in the monthly attack frequency at week 12 between the two groups (using migraine diary). Secondary efficacy measures were assessed using several clinical, functional, and psychological instruments. We performed both complete case (CC) and intention‐to‐treat analyses (ITT).ResultsTwenty‐five patients in the memantine group and 27 patients in the placebo group completed the study. Patients in the memantine group showed significantly greater reduction (mean change; 3.4; 95%CI, 2.3‐4.4) in the monthly attack frequency than the placebo group (mean change, 1.0; 95%CI, 0.3‐1.7) (mean difference [MD], 2.3; 95%CI, 1.1‐3.5, P < .001). Both CC (MD, 4.9; 95%CI, 2.6‐7.2 days), and ITT analyses (MD, 5.2; 95%CI, 2.0‐8.5) showed significantly higher reduction in the mean number of migraine days in the memantine group than the placebo group (P < .01). Patients in the memantine group experienced greater reduction in the number of work absence days, severity, and disability score than the patients in the placebo group in both ITT and CC analyses. Changes in quality of life, sleep, depression, and anxiety did not differ between the two groups. Three patients in the memantine group complained of sedation, mild vertigo and nausea, and drowsiness. In the placebo group, one patient complained of nausea and another patient discontinued treatment after 2 weeks due to vertigo.ConclusionMemantine might be a tolerable and efficacious option for prophylaxis in patients with migraine without aura. Tolerability, short duration required for titration, and safety profile in pregnancy might give memantine an advantage over other antimigraine medications. The study was registered in the Iranian Registry of Clinical Trials (Registration number: IRCT2013120115616N1).

AbstractBackground and objectiveAs compliance of continuous positive airway pressure (CPAP) for treatment of obstructive sleep apnoea (OSA) is often suboptimal, a less cumbersome treatment is desirable. We explored the clinical usefulness of nasal positive end expiratory pressure (nPEEP) valves.MethodsSymptomatic OSA patients (apnoea hypopnea index (AHI) >5/h by polysomnography (PSG) or >10/h by type III devices), who declined CPAP, were recruited. A nPEEP valve was attached to each nostril before bed. After successful acclimatization for 1 week, treatment was continued for 4 weeks. The nPEEP valves provided expiratory resistance to build up PEEP. PSG was performed at week 4.ResultsAmong 196 subjects, 46 (23%) failed acclimatization and 14 (7%) withdrew. Among the 120 patients with a valid PSG, 72 (60%) and 75 (63%) had >50% reduction in mean (standard deviation) overall AHI 26 (16)/h to 18 (18)/h and mean supine AHI 31 (19)/h to 11(16)/h, respectively, P < 0.001. Compared with responders, patients with <50% reduction in AHI had a higher mean overall AHI (30/h vs 23/h, P = 0.03), higher mean supine AHI (35/h vs 26/h, P = 0.04), more severe mean oxygen desaturation nadir (76.7% vs 82.7%, P < 0.01) and longer mean period of desaturation <90% SaO2 (7.7 vs 2.4, P = 0.02). Breathing discomfort and dry mouth were the most common side effects. Compared with a dental device, there was a larger mean reduction in supine AHI using nPEEP (29 (14)/h vs 16 (17)/h).ConclusionnPEEP valves were useful in selected patients with mild or positional‐related OSA.
Price Rigidity, Inflation and the Distribution of Relative Price Changes
Authors: Rather Sartaj Rasool , Durai S. Raja Sethu , Ramachandran M. 
Published: December 2015

This study examines whether skewness of the cross-sectional distribution of relative price changes is positively associated with aggregate inflation as predicted by the menu cost model of Ball and Mankiw (1994, 1995). Further, the study examines the size and frequency of price changes across various commodities and the distribution of relative price changes. The results from highly disaggregated Indian wholesale price index (WPI) data suggest that the skewness of relative price changes explains a significant proportion of short-run fluctuations in aggregate inflation. More importantly, the results indicate that the average size of price increases is greater than the size of price decreases implying downwards rigidity in the prices of various commodities.

Highly Efficient Olefin Hydrosilylation Catalyzed by Iron Complexes with Iminobipyridine Ligand
Authors: Hayasaka Kazumasa , Kamata Kouji , Nakazawa Hiroshi 
Published: December 2015

Abstract
Several iron complexes bearing an iminobipyridine ligand, (RBPIAr)FeBr2 (R = H, Me; Ar = Mes, Dipp), were synthesized. These iron complexes exhibited high catalytic activities with the help of NaBHEt3 for the hydrosilylation of 1-octene with primary, secondary, and tertiary silanes. The reaction between 1-octene and PhSiH3 produced three different species: mono- (Ph(octyl)SiH2), di- (Ph(octyl)2SiH), and trialkylated (Ph(octyl)3Si) silanes. The selective formation of Ph(octyl)SiH2 and Ph(octyl)2SiH could be achieved under different conditions. Single or double hydrosilylation reactions of secondary silanes (PhMeSiH2 and Ph2SiH2) afforded tertiary and quaternary silanes, respectively. The iron iminobipyridine complexes exhibited catalytic activity in organic solvents such as hexane, toluene, diethyl ether, and THF; an appropriate solvent choice could reverse the mono/dialkylated selectivity of the reacting silanes. In addition, a high catalyst turnover number of 12038 was achieved for the reaction between 1-octene and Ph2SiH2, and the catalyst remained active at 100 °C without any loss of activity.

Mother Earth tied to the train tracks: The scriptive implications of melodrama in climate change discourse
Authors: Mancus Shannon Davies 
Published: December 2015

Abstract
This article examines the way climate change narratives have mobilized melodramatic frameworks, by examining An Inconvenient Truth (Guggenheim, 2006) as paradigmatic. It engages with recent scholarship that recuperates melodrama from the realm of the pejorative to observe how it structures political discourse and expands on that scholarship by introducing a performance studies methodology to examine how melodrama offers the broad outlines of a script that the would-be hero is asked to improvise within. The essay examines the tropes of melodrama – which include Manichaean dichotomies of good and evil, the implication that suffering is a marker of virtue, and the imperative of a dialectic of pathos and action – in order to analyse their implications for the potential to solve the impending tragedy of devastating climate change. This essay engages in close readings of performances structured by generic scriptive discourse to argue that, for climate change activists, the forms that environmental narratives take, may communicate as much as the content of those narratives.

Beyond Time-on-Task: The Relationship Between Spaced Study and Certification in MOOCs
Authors: Miyamoto Yohsuke Roy , Coleman Cody , Williams Joseph Jay , Whitehill Jacob , Nesterko Sergiy , Reich Justin 
Published: December 2015

A long history of laboratory and field experiments has demonstrated that dividing study time into many sessions is often superior to massing study time into few sessions, a phenomenon widely known as the “spacing effect.” Massive open online courses (MOOCs) collect abundant data about student activity over time, but little of its early research has used learning theory to interrogate these data. Taking inspiration from this psychology literature, here we use data collected from MOOCs to identify observational evidence for the benefits of spaced practice in educational settings. We investigated tracking logs from 20 HarvardX courses to examine whether there was any relationship between how students allocated their participation and what performance they achieved. While controlling for the effect of total time on-site, we show that the number of sessions students initiate is an important predictor of certification rate, across students in all courses. Furthermore, we demonstrate that when students spend similar amounts of time in multiple courses, they perform better in courses where that time is distributed among more sessions, suggesting the benefit of spaced practice independently of student characteristics. We conclude by proposing interventions to guide students’ study schedules and for leveraging such an effect.
