Feasibility and safety of same-day home discharge after radiofrequency catheter ablation

Interventional cardiology in a day-case setting might reduce logistic constraints on hospital resources. However, in contrast with coronary angioplasty, few data support the feasibility and safety of radiofrequency catheter ablation (RCA). The aim of this prospective, multicenter cohort study was to evaluate the feasibility and safety of RCA in 1,342 patients (814 men; mean age 57 +/- 17 years) considered eligible for ambulatory RCA, according to specific set of criteria, for common atrial flutter (n = 632), atrioventricular nodal reentrant tachycardia (n = 436), accessory pathways (n = 202), and atrial tachycardia (n = 72). Patients suitable for early discharge (4 to 6 hours after uncomplicated RCA) were scheduled for 1-month follow-up. Predictive factors for delayed complications were studied by multivariate analysis. Of the 1,342 enrolled patients, 1,270 (94.6%) were discharged the same day and followed for 1 month; no deaths occurred, and the readmission rate was 0.79% (95% confidence interval 0.30% to 1.27%). Six patients had significant puncture complications, 2 presented with symptomatic delayed pulmonary embolism, and 2 had new onset of poorly tolerated atrial flutter. None of these complications was life threatening. Multivariate analysis did not identify any significant independent predictors for delayed complications. In conclusion, these data suggest that same-day discharge after uncomplicated RCA for routine supraventricular arrhythmias is safe and may be applicable in clinical practice. This approach is known to be associated with significant patient satisfaction and cost savings and can be considered a first-line option in most patients who undergo routine ablation procedures.

Regulations on E-Commerce Consumer Protection Rules in China and Europe Compared – Same Same but Different?

This article provides a comprehensive overview of the regulations on e-commerce protection rules in China and the European Union. It starts by giving a general overview of different approaches towards consumer protection in e-commerce. This article then scrutinizes the current legal system in China by mainly focusing on SAIC’s “Interim Measures for the Administration of Online Commodity Trading and Relevant Service Activities”. The subsequent chapter covers the supervision of consumer protection in e-commerce in China, which covers both the regulatory objects of online commodity trading and the applied regulatory mechanisms. While the regulatory objects include operating agents, operating objects, operating behavior, electronic contracts, intellectual property and consumer protection, the regulatory mechanisms for e-commerce in China combines market mechanism and industry self-discipline under the government’s administrative regulation. Further, this article examines the current European legal system in online commodity trading. It outlines the aim and the scope of EU legislation in the respective field. Subsequently, the paper describes the European approach towards the supervision of consumer protection in e-commerce. As there is no central EU agency for consumer protection in e-commerce transactions, the EU stipulates a framework for Member States’ institutions, thereby creating a European supervisory network of Member States’ institutions and empowers private consumer organisations to supervise the market on their behalf. Moreover, the EU encourages the industry to self- or co-regulate e-commerce by providing incentives. Consequently, this article concludes that consumer protection may be achieved by different means and different systems. However, even though at first glance the Chinese and the European system appear to differ substantially, a closer look reveals tendencies of convergence between the two systems.

Are Today’s Medical School Graduates Performing the Same Number of Medical Procedures Compared to Graduates Ten Years Ago? A case for Simulation?

INTRODUCTION: Medical schools are charged with providing both a strong basic science and clinical curriculum for their students. In most institutions instruction in performing the core clinical procedures is part of the curriculum, but because of many constraints do medical students practice these procedures as many times as medical students in the past? Several studies have concluded that medical students today feel incompetent to perform basic clinical procedures at the time of graduation. [See PDF for complete abstract]

Extending in vitro conditioning in Aplysia to analyze operant and classical processes in the same preparation.

Operant and classical conditioning are major processes shaping behavioral responses in all animals. Although the understanding of the mechanisms of classical conditioning has expanded significantly, the understanding of the mechanisms of operant conditioning is more limited. Recent developments in Aplysia are helping to narrow the gap in the level of understanding between operant and classical conditioning, and have raised the possibility of studying the neuronal processes underlying the interaction of operant and classical components in a relatively complex learning task. In the present study, we describe a first step toward realizing this goal, by developing a single in vitro preparation in which both operant and classical conditioning can be studied concurrently. The new paradigm reproduced previously published results, even under more conservative and homogenous selection criteria and tonic stimulation regime. Moreover, the observed learning was resistant to delay, shortening, and signaling of reinforcement.

New Journal, Same Ongoing Challenge: Advancing Policies that Promote the Health and Well-Being of Children and Families

The publication of the inaugural issue of the Journal of Applied Research on Children is a notable milestone for its sponsoring organization, CHILDREN AT RISK (www.childrenatrisk.org). With the release of “Volume 1, Number 1,” we as the Co-Editors in Chief would like to take the opportunity to thank the inaugural contributors whose articles follow and to answer the obvious question of “Why publish a new journal?”

Initiation and continuation of randomized trials after the publication of a trial stopped early for benefit asking the same study question: STOPIT-3 study design

BACKGROUND Randomized control trials (RCTs) stopped early for benefit (truncated RCTs) are increasingly common and, on average, overestimate the relative magnitude of benefit by approximately 30%. Investigators stop trials early when they consider it is no longer ethical to enroll patients in a control group. The goal of this systematic review is to determine how investigators of ongoing or planned RCTs respond to the publication of a truncated RCT addressing a similar question. METHODS/DESIGN We will conduct systematic reviews to update the searches of 210 truncated RCTs to identify similar trials ongoing at the time of publication, or started subsequently, to the truncated trials ('subsequent RCTs'). Reviewers will determine in duplicate the similarity between the truncated and subsequent trials. We will analyze the epidemiology, distribution, and predictors of subsequent RCTs. We will also contact authors of subsequent trials to determine reasons for beginning, continuing, or prematurely discontinuing their own trials, and the extent to which they rely on the estimates from truncated trials. DISCUSSION To the extent that investigators begin or continue subsequent trials they implicitly disagree with the decision to stop the truncated RCT because of an ethical mandate to administer the experimental treatment. The results of this study will help guide future decisions about when to stop RCTs early for benefit.

New Name, New Format, New Publisher, Same Principles and Values

Still keen on being a definitive record on developments in family strengths and parenting, the Journal is devoted to presenting theory, practice and evaluation articles on the strengths perspective in family preservation practice, all to assure and improve services and programs that promote and sustain family systems.

Tel Aviv - Mumbai - Tel Aviv: Same-Sex couples seeking parenthood in India

In Israel religious belonging remains a central category of citizenship. Laws concerning reproductive technologies such as the surrogacy law from 1996 are strongly informed by Orthodox rabbis’ kinship concepts (Kahn 2000, Shalev 1998, Weisberg 2005). A set of regulations secures that heterosexual Jewish couples bring into being children who are unequivocally Jewish themselves. The Israeli surrogacy law can therefore be understood as part of a policy seeking to reproduce the boundaries of the Jewish-Israeli collective. Same-sex couples do not fit this narrow definition of family and have no access to surrogacy in Israel. Yet gay couples maintain that parenthood is a universal civil right and bypass their exclusion through surrogacy arrangements abroad. The proposed paper follows these couples to Mumbai, which has become a popular destination for surrogacy in recent years. After their children’s birth the couples spend three to five weeks in India. In this time they not only take on their new tasks as fathers. They are also occupied with the bureaucracy of disconnecting the children from India and turning them into Israeli citizens. The paper elaborates on the bureaucratic processes and the hurdles same-sex couples encounter when seeking recognition of their parenthood and citizenship for their children. It unveils the intricacies and ramifications of Israel’s contradicting surrogacy policy of enforcing narrow definitions of family inside the country and simultaneously outsourcing problematic cases.

NGRIP CH4 concentration from 120 to 10 kyr before present and its relation to a δ15N temperature reconstruction from the same ice core

During the last glacial cycle, Greenland temperature showed many rapid temperature variations, the so-called Dansgaard–Oeschger (DO) events. The past atmospheric methane concentration closely followed these temperature variations, which implies that the warmings recorded in Greenland were probably hemispheric in extent. Here we substantially extend and complete the North Greenland Ice Core Project (NGRIP) methane record from the Preboreal Holocene (PB) back to the end of the last interglacial period with a mean time resolution of 54 yr. We relate the amplitudes of the methane increases associated with DO events to the amplitudes of the local Greenland NGRIP temperature increases derived from stable nitrogen isotope (δ15N) measurements, which have been performed along the same ice core (Kindler et al., 2014). We find the ratio to oscillate between 5 parts per billion (ppb) per °C and 18 ppb °C−1 with the approximate frequency of the precessional cycle. A remarkably high ratio of 25.5 ppb °C−1 is reached during the transition from the Younger Dryas (YD) to the PB. Analysis of the timing of the fast methane and temperature increases reveals significant lags of the methane increases relative to NGRIP temperature for DO events 5, 9, 10, 11, 13, 15, 19, and 20. These events generally have small methane increase rates and we hypothesize that the lag is caused by pronounced northward displacement of the source regions from stadial to interstadial. We further show that the relative interpolar concentration difference (rIPD) of methane is about 4.5% for the stadials between DO events 18 and 20, which is in the same order as in the stadials before and after DO event 2 around the Last Glacial Maximum. The rIPD of methane remains relatively stable throughout the full last glacial, with a tendency for elevated values during interstadial compared to stadial periods.

Do Cognitive and behavioral assessments of executive functions measure the same concept in children born very preterm?

Aims: This study investigated whether children aged between 8 - 12 years born very preterm (VPT) and/or at very low birth weight (VLBW) performed lower than same-aged term-born controls in cognitive and behavioral aspects of three executive functions: inhibition, working memory, and shifting. Special attention was given to sex differences. Methods: Fifty-two VPT/VLBW children (26 girls) born in the cohort of 1998–2003 at the Children’s University Hospital in Bern, Switzerland, and 36 same-aged term-born controls (18 girls) were recruited. As cognitive measures, children completed tasks of inhibition (Colour-Word Interference Test, D-KEFS), working memory (digit span backwards, WISC-IV) and shifting (Trail Making Test, number-letter switching, D-KEFS). As behavioral measures, mothers completed the Behavior Rating Inventory of Executive Function (BRIEF), assessing executive functions in everyday life.
