NRXN3 Is a Novel Locus for Waist Circumference: A Genome-Wide Association Study from the CHARGE Consortium

Central abdominal fat is a strong risk factor for diabetes and cardiovascular disease. To identify common variants influencing central abdominal fat, we conducted a two-stage genome-wide association analysis for waist circumference (WC). In total, three loci reached genome-wide significance. In stage 1, 31,373 individuals of Caucasian descent from eight cohort studies confirmed the role of FTO and MC4R and identified one novel locus associated with WC in the neurexin 3 gene [NRXN3 (rs10146997, p = 6.4×10−7)]. The association with NRXN3 was confirmed in stage 2 by combining stage 1 results with those from 38,641 participants in the GIANT consortium (p = 0.009 in GIANT only, p = 5.3×10−8 for combined analysis, n = 70,014). Mean WC increase per copy of the G allele was 0.0498 z-score units (0.65 cm). This SNP was also associated with body mass index (BMI) [p = 7.4×10−6, 0.024 z-score units (0.10 kg/m2) per copy of the G allele] and the risk of obesity (odds ratio 1.13, 95% CI 1.07–1.19; p = 3.2×10−5 per copy of the G allele). The NRXN3 gene has been previously implicated in addiction and reward behavior, lending further evidence that common forms of obesity may be a central nervous system-mediated disorder. Our findings establish that common variants in NRXN3 are associated with WC, BMI, and obesity

Age differences in moral judgment: Older adults are more deontological than younger adults

In 2 studies, an older and a younger age group morally evaluated dilemmas contrasting a deontological judgment (do not harm others) against a utilitarian judgment (do what is best for the majority). Previous research suggests that deontological moral judgments are often underpinned by affective reactions and utilitarian moral judgments by deliberative thinking. Separately, research on the psychology of aging has shown that affect plays a more prominent role in the judgments and decision making of older (vs. younger) adults. Yet age remains a largely overlooked factor in moral judgment research. Here, we therefore investigated whether older adults would make more deontological judgments on the basis of experiencing different affective reactions to moral dilemmas as compared with younger adults. Results from 2 experiments indicated that older adults made significantly more deontological moral judgments. Mediation analyses revealed that the relationship between age and making more deontological moral judgments is partly explained by older adults exhibiting significantly more negative affective reactions and having more morally idealistic beliefs as compared with younger adults

What Makes Retirees Happier: A Gradual or 'Cold Turkey' Retirement?

This study explores the factors that affect an individual’s happiness while transitioning into retirement. Recent studies highlight gradual retirement as an attractive option to older workers as they approach full retirement. However, it is not clear whether phasing or cold turkey makes for a happier retirement. Using longitudinal data from the Health and Retirement Study, this study explores what shapes the change in happiness between the last wave of full employment and the first wave of full retirement. Results suggest that what really matters is not the type of transition (gradual retirement or cold turkey), but whether people perceive the transition as chosen or forced

Creating a User-steerable Media Presentation-system as a Canadian/Australian Distance-Learning Research Project

This paper describes an online architecture for creating a user-steerable interactive documentary from a database of edited media-sequences. Using a spreading activation net, meta-tagged content-sequences are recommended to users based on their previous selections, proving an automatically contextually-relevant path through video content. The system supports lean-forward interactivity with users constantly making choices, as well as lean-back behaviours in which the system automatically makes choices automatically. User-ratings, social networking features and user assembled micro-narratives are also supported. The system is currently running with professionally-produced content as an interactive documentary on the global diamond trade

COVID-19: patient safety and quality improvement skills to deploy during the surge

The COVID-19 pandemic has suddenly challenged many healthcare systems. To respond to the crisis, these systems have had to reorganize instantly, with little time to reflect on the roles to assign to their patient safety (PS) and quality improvement (QI) experts. In many cases, staff who had a background in clinical care was called to support wards and critical care. Others were deemed “non-essential” and sent back to work from home, while their programmes were placed in hibernation mode. This has meant that many QI and PS experts with skills to offer in their field have ended up carrying out tasks unrelated to the current crisis. We believe that the skillset of patient safety and quality improvement personnel is essential for the successful implementation of the changes required to achieve the desired outcomes. An understanding of systems theory and the complexity of healthcare systems, human factors and reliability theories, and change methodologies is key to the success of any transformation programme. Here, we suggest a five-step strategy and actions through which PS and QI staff can meaningfully contribute during a pandemic by employing their core skills to support patients, staff and organizations: 1. Strengthen the system by assessing readiness, gathering evidence, setting up training, promoting staff safety and bolstering peer support. 2. Engage with citizens, patients and their families so that the solutions are jointly achieved and owned by both the healthcare providers and the people who receive care and in particular the citizens who are required to undertake preventive interventions. 3. Work to improve care, through actions such as the separation of flows, flash workshops on teamwork and the development of clinical decision support. 4. Reduce harm by proactively managing risk to both COVID-19 and non-COVID-19 patients. 5. Boost and expand the learning system, to capture improvement opportunities, adjust very rapidly and develop resilience. This is crucial as little is known about COVID-19 and its impacts on patients, staff and institutions

Simultaneous Quantitation of Antibodies to Neutralizing Epitopes on Virus-Like Particles for Human Papillomavirus Types 6, 11, 16, and 18 by a Multiplexed Luminex Assay

Several different methods have been developed to quantitate neutralizing antibody responses to human papillomaviruses (HPVs), including in vivo neutralization assays, in vitro pseudoneutralization assays, competitive radioimmunoassays (cRIAs), and enzyme-linked immunosorbent assays. However, each of these techniques possesses one or more limitations that preclude testing large numbers of patient sera for use in natural history studies and large vaccine clinical trials. We describe here a new multiplexed assay, by using the Luminex Laboratory MultiAnalyte Profiling (LabMAP3) assay system, that can simultaneously quantitate neutralizing antibodies to human papillomavirus types 6, 11, 16, and 18 in 50 μl of serum. The HPV-Luminex competitive immunoassay measures titers of polyclonal antibodies in serum capable of displacing phycoerythrin-labeled detection monoclonal antibodies binding to conformationally sensitive, neutralizing epitopes on the respective virus-like particles. This competitive Luminex immunoassay was found to be as sensitive, accurate, and precise as the currently used cRIAs. An effective HPV vaccine will most likely require several distinct genotypes to protect against multiple cancer causing papillomaviruses. The HPV-Luminex immunoassay should prove to be a useful tool in simultaneously quantitating antibody immune responses to multiple HPV genotypes for natural history infection studies and for monitoring the efficacy of prospective vaccines
