Background: As part of 'The Hub' project at Wellcome Collection, a team of eight co-researchers with learning disabilities alongside academics created an online survey to challenge public understanding of learning disabilities. Using creative and arts-based methods, co-researchers remotely co-analysed the survey results amid Covid-19 lockdown challenges. Here, we explore our unexpected 'transition' journey from the physical 'Hub' to the digital space.

Through a process of robust co-design, we created a bespoke accessible survey platform to explore the role of co-researchers with learning disabilities (LDs) in research design and analysis. A team of co-researchers used this system to create an online survey to challenge public understanding of LDs [3]. Here, we describe and evaluate the process of remotely co-analyzing the survey data across 30 meetings in a research team consisting of academics and non-academics with diverse abilities amid new COVID-19 lockdown challenges.

Background: Ventricular tachycardia (VT) catheter ablation success may be limited when transcutaneous epicardial access is contraindicated. Surgical ablation (SurgAbl) is an option, but ablation guidance is limited without simultaneously acquired electrophysiological data.

Objective: We describe our SurgAbl experience utilizing contemporary electroanatomic mapping (EAM) among patients with refractory VT storm.

Article Synopsis
  • The study examines the effectiveness and safety of repeat ablation procedures for treating ventricular arrhythmias in patients with nonischemic cardiomyopathy (NICM).* -
  • Among the 88 NICM patients analyzed, those requiring multiple ablations had similar survival rates from arrhythmias as those who had only one, but experienced higher complication rates and used more nonstandard ablation methods.* -
  • Midmyocardial substrate (MMS) presence was linked to a higher need for repeat procedures; however, with multiple ablations, the outcomes in terms of arrhythmia-free survival were comparable to those without MMS.*

A series of chalcogen analogues encompassing a ketone and chalcogenoketones [{PC(=E)P}Pd(PMe )] (E=O, S, Se, Te) was generated from a nucleophilic palladium carbene compound, [{PC(sp )P}Pd(PMe )] ([PC(sp )HP]=bis[2-(diisopropylphosphino)-phenyl]methyl, iPr P-C H -CH-C H -PiPr ). The thio-, seleno-, and telluroketone were all synthesized by means of an atom transfer from the respective chalcogens. The ketone analogue, however, required the use of nitrobenzene or nitrosobenzene as the oxygen-atom transfer agent.

The ability to reproduce visually presented actions has been studied through neuropsychological observations of patients with ideomotor apraxia. These studies include attempts to understand the neural basis of action reproduction based on lesion-symptom mapping in different patient groups. While there is a convergence of evidence that areas in the parietal and frontal lobes within the left hemisphere are involved in the imitation of a variety of actions, questions remain about whether the results generalize beyond the imitation of tool use and whether the presence of a strong grasp component of the action is critical.

Purpose: Percutaneous placement of transcatheter prosthetic aortic valves without cardiopulmonary bypass (CPB) continues to gain clinical acceptance. However, information on pressure-loading characteristics of the aortic root/annular areas is limited. For this reason, we designed a preclinical model, implanting an aortic root load transducer with a power source/telemetry system for chronic, conscious, loading data acquisition.

CogWatch is an assistive system to re-train stroke survivors suffering from Apraxia or Action Disorganization Syndrome (AADS) to complete activities of daily living (ADLs). This paper describes the approach to real-time planning based on a Markov Decision Process (MDP), and demonstrates its ability to improve task's performance via user simulation. The paper concludes with a discussion of the remaining challenges and future enhancements.

Unlabelled: In last the 50 years many studies have described the causes of mortality. In newborns and infants between 5 and 6 months the risk is higher. The heart is not developed as in older/grown child and these infants need more oxygen than the older ones.

The authors studied the single-pass pulmonary extraction of the potent local anesthetic, bupivacaine, in 21 anesthetized rabbits. Pulmonary extraction of [3H]bupivacaine and [14C]5-hydroxytryptamine (5-HT) was quantified from multiple indicator-dilution outflow curves using indocyanine green as the intravascular reference substance. Pulmonary extraction at control (n = 15; mean +/- S.

A pharmacokinetic evaluation of bupivacaine was carried out after intercostal nerve blocks performed on 28 occasions in 27 children varying in age from 3 months to 16 yr. Bupivacaine HCl, 0.5%, with epinephrine 1:200,000 was employed.

Two infants with pulmonary atresia are presented, wherein a large, vertically oriented patent ductus arteriosus, acting as the only source of pulmonary blood supply, compressed the left bronchus, causing significant respiratory distress. Hyperinflation of the left lung was the clue to this circumstance. After bronchographic confirmation, surgical repair was accomplished by placement of aortopulmonary shunts and division of the patent ductus.
