RESUMEN
BACKGROUND: Randomised controlled trials are often beset by problems with poor recruitment and retention. Information to support decisions on trial participation is usually provided as printed participant information sheets (PIS), which are often long, technical, and unappealing. Multimedia information (MMI), including animations and videos, may be a valuable alternative or complement to a PIS. The Trials Engagement in Children and Adolescents (TRECA) study compared MMI to PIS to investigate the effects on participant recruitment, retention, and quality of decision-making. METHODS: We undertook six SWATs (Study Within A Trial) within a series of host trials recruiting children and young people. Potential participants in the host trials were randomly allocated to receive MMI-only, PIS-only, or combined MMI + PIS. We recorded the rates of recruitment and retention (varying between 6 and 26 weeks post-randomisation) in each host trial. Potential participants approached about each host trial were asked to complete a nine-item Decision-Making Questionnaire (DMQ) to indicate their evaluation of the information and their reasons for participation/non-participation. Odds ratios were calculated and combined in a meta-analysis. RESULTS: Data from 3/6 SWATs for which it was possible were combined in a meta-analysis (n = 1758). Potential participants allocated to MMI-only were more likely to be recruited to the host trial than those allocated to PIS-only (OR 1.54; 95% CI 1.05, 2.28; p = 0.03). Those allocated to combined MMI + PIS compared to PIS-only were no more likely to be recruited to the host trial (OR = 0.89; 95% CI 0.53, 1.50; p = 0.67). Providing MMI rather than PIS did not impact on DMQ scores. Once children and young people had been recruited to host trials, their trial retention rates did not differ according to intervention allocation. CONCLUSIONS: Providing MMI-only increased the trial recruitment rate compared to PIS-only but did not affect DMQ scores. Combined MMI + PIS instead of PIS had no effect on recruitment or retention. MMIs are a useful tool for trial recruitment in children and young people, and they could reduce trial recruitment periods.

Governments have responded to the Covid-19 crisis through various measures designed to reduce transmission and protect people judged to be at heightened risk. This paper explores the implications of such measures in the UK for disabled people, with a particular focus on measures designed to reduce and reshape the use of streets and public space. We divide UK measures into two broad categories. First, there are measures designed to reduce the use of streets and public spaces - e.g., rules requiring people to stay at home except in tightly prescribed circumstances and measures providing specific support (including food delivery and priority online shopping) for people designated as clinically extremely 'vulnerable'. Second, there are measures designed to control the behaviour of people using streets and public space - e.g., rules on physical distancing and the use of face coverings. We explore the disability-related concerns associated with these types of measure. We also highlight the opportunities this crisis presents for embedding accessibility and inclusion more firmly into the fabric of our streets and call for renewed resistance to policies and practices shaped by ableist assumptions and attitudes.
Les gouvernements réagissent à la crise de Covid-19 en prenant diverses mesures pour réduire sa transmission et pour protéger les personnes jugées à haut risque. Cet article explore les implications de ces mesures au Royaume-Uni pour les personnes handicapées, en se concentrant sur celles conçues pour réduire et remodeler l'utilisation des rues et des espaces publics. Nous divisons les mesures en deux catégories. Premièrement, il existe des mesures conçues pour réduire l'utilisation des rues et espaces publics par exemple, les règles obligeant les personnes à rester chez eux, sauf dans les circonstances strictement prescrites et les mesures qui nécessitent un soutien spécifique (y compris la livraison de nourriture et les achats en ligne prioritaires) pour les personnes désignées comme « vulnérables ¼. Deuxièmement, il existe des mesures conçues pour contrôler le comportement des personnes qui utilisent ces espaces par exemple, les règles sur la distance physique et l'utilisation des masques. Nous explorons les préoccupations liées au handicap associées à ces types de mesures. Nous soulignons également les opportunités présentées par cette crise pour intégrer plus fermement l'accessibilité et l'inclusion dans la trame sociale de nos rues et faisons appel à une résistance renouvelée aux politiques façonnées par les attitudes capacitistes.
RESUMEN
To improve health outcomes in people living with HIV, adoption of evidence-based interventions (EBIs) using effective and transferable implementation strategies to optimise the delivery of healthcare is needed. ViiV Healthcare's Positive Pathways initiative was established to support the UNAIDS 90-90-90 goals. A compendium of EBIs was developed to address gaps within the HIV care continuum, yet it was unknown whether efforts existed to adapt and implement these EBIs across diverse clinical contexts. Therefore, this review sought to report on the use of implementation science in adapting HIV continuum of care EBIs. A systematic literature review was undertaken to summarise the evaluation of implementation and effectiveness outcomes, and report on the use of implementation science in HIV care. Ten databases were reviewed to identify studies (time-period: 2013-2018; geographic scope: United States, United Kingdom, France, Germany, Italy, Spain, Canada, Australia and Europe; English only publications). Studies were included if they reported on people living with HIV or those at risk of acquiring HIV and used interventions consistent with the EBIs. A broad range of study designs and methods were searched, including hybrid designs. Overall, 118 publications covering 225 interventions consistent with the EBIs were identified. These interventions were evaluated on implementation (N = 183), effectiveness (N = 81), or both outcomes (N = 39). High variability in the methodological approaches was observed. Implementation outcomes were frequently evaluated but use of theoretical frameworks was limited (N = 13). Evaluations undertaken to assess effectiveness were inconsistent, resulting in a range of measures. This review revealed extensive reporting on implementation science as defined using evaluation outcomes. However, high variability was observed in how implementation outcomes and effectiveness were defined, quantified, and reported. A more specific and consistent approach to conducting and reporting on implementation science in HIV could facilitate achievement of UNAIDS 90-90-90 targets.

Objective: We developed a system for the discovery of foodborne illness mentioned in online Yelp restaurant reviews using text classification. The system is used by the New York City Department of Health and Mental Hygiene (DOHMH) to monitor Yelp for foodborne illness complaints. Materials and Methods: We built classifiers for 2 tasks: (1) determining if a review indicated a person experiencing foodborne illness and (2) determining if a review indicated multiple people experiencing foodborne illness. We first developed a prototype classifier in 2012 for both tasks using a small labeled dataset. Over years of system deployment, DOHMH epidemiologists labeled 13 526 reviews selected by this classifier. We used these biased data and a sample of complementary reviews in a principled bias-adjusted training scheme to develop significantly improved classifiers. Finally, we performed an error analysis of the best resulting classifiers. Results: We found that logistic regression trained with bias-adjusted augmented data performed best for both classification tasks, with F1-scores of 87% and 66% for tasks 1 and 2, respectively. Discussion: Our error analysis revealed that the inability of our models to account for long phrases caused the most errors. Our bias-adjusted training scheme illustrates how to improve a classification system iteratively by exploiting available biased labeled data. Conclusions: Our system has been instrumental in the identification of 10 outbreaks and 8523 complaints of foodborne illness associated with New York City restaurants since July 2012. Our evaluation has identified strong classifiers for both tasks, whose deployment will allow DOHMH epidemiologists to more effectively monitor Yelp for foodborne illness investigations.

The ability to bond restorations to dentine successfully is central to minimally invasive restorative dentistry. While dentine-bonding agents have gone through a variety of 'generations', it is the purpose of this paper to describe the latest dentine-bonding agents, the Universal Bonding Agents. These materials may be considered 'Universal' insofar as they may be considered to be capable of being used for direct and indirect dentistry, as well as being suitable for use in whichever etching modality the clinician considers appropriate, namely self-etch, etch and rinse or selective enamel etch. Laboratory investigations and initial clinical studies hold the promise that Universal Bonding Agents are a forward step in the quest for the ultimate bond to tooth substance. Clinical relevance: New Universal Bonding Agents appear to present a promising advance in bonding to dentine.

Planned relaparotomy is a technique in which two or more surgeries are planned before or during the initial surgery. Two dogs underwent planned relaparotomy for severe peritonitis secondary to gastric ulceration and linear foreign body. Both dogs had good outcomes, and unnecessary procedures that would likely have led to increased morbidity were avoided. This technique may be useful in avoiding unnecessary procedures as well as providing for better stabilization of the animal.
