Multiple logistic regression was used to determine variables associated with the primary outcome. Results A total of 1,077 VLBW infants were eligible. After launching BFB, MMF at discharge increased in VLBW infants, from 35.2% to 46.0%, p  less then  0.001. Median time to pump initiation decreased from 11 to 5 hours after 2012, p = 0.0001. Factors significantly associated with receiving MMF at discharge included birth post-BFB; private insurance; non-Black race; shorter length of stay; older maternal age; and mother's milk as first feeding. Conclusions Hospital culture supportive of breastfeeding impacts not only healthy term infants but also VLBW infants. Earlier initiation of milk expression significantly improves provision of MMF to preterm infants at discharge.Surface chemical compounds are key components of survival and reproduction in many species. Cuticular hydrocarbons (CHCs) are chemical compounds produced by all insects that are used for both desiccation resistance and chemical communication, including communication related to mating. In the species pair of Drosophila melanogaster and D. simulans, female CHCs stimulate conspecific males to mate and repel heterospecific males. While CHCs are a critical contributor to both reproductive success within a species and isolation between species, few genes underlying species variation in CHC profiles are known. Here, we use genetic mapping of the 3rd chromosome to test a suite of candidate genes for interspecies variation in CHCs. Candidate gene CG5946 was found to be involved in species differences in the production of 7,11-heptacosadiene and 7-tricosene between D. melanogaster and D. simulans. This is therefore a new candidate locus contributing to species-specific variation in the CHC profile. In the process of mapping genes for CHCs, we also identified 29 candidate genes for the reduced survival or inviability of interspecies hybrids.The global effort to develop a coronavirus disease 2019 (COVID-19) vaccine is on track to produce one or more authorized vaccines. We examine how different definitions and thresholds of vaccine efficacy, coupled with different levels of implementation effectiveness and background epidemic severity, translate into outcomes including cumulative infections, hospitalizations, and deaths. Using a mathematical simulation of vaccination, we find that factors related to implementation will contribute more to the success of vaccination programs than a vaccine's efficacy as determined in clinical trials. The benefits of a vaccine will decline substantially in the event of manufacturing or deployment delays, significant vaccine hesitancy, or greater epidemic severity. Our findings demonstrate the urgent need for health officials to invest greater financial resources and attention to vaccine production and distribution programs, to redouble efforts to promote public confidence in COVID-19 vaccines, and to encourage continued adherence to other mitigation approaches, even after a vaccine becomes available.The Food and Drug Administration (FDA) approves vaccines when their benefits outweigh the risks for their intended use. In this article we review the standard FDA approach to vaccine evaluation, which underpins its current approaches to assessment of vaccines to prevent coronavirus disease 2019 (COVID-19). The FDA has established pathways to accelerate vaccine availability before approval, such as Emergency Use Authorization, and to channel resources to high-priority products and allow more flexibility in the evidence required for approval, including accelerated approval based on surrogate markers of effectiveness. Among the thirty-five new vaccines approved in the US from 2006 through October 2020, about two-thirds of their pivotal trials used the surrogate outcome of immune system response, and only one-third evaluated actual disease incidence. Postapproval safety surveillance of new vaccines, and particularly vaccines receiving expedited approval, is crucial. This has generally been accomplished through such mechanisms as the Centers for Disease Control and Prevention (CDC) and FDA Vaccine Adverse Event Reporting System, the CDC Vaccine Safety Datalink, and the CDC Clinical Immunization Safety Assessment Project. Adverse events detected in this way may lead to changes in a vaccine's recommended use or withdrawal from the market. Regulatory oversight of new vaccines must balance speed with rigor to effectively address the pandemic.Prices send signals about consumer preferences and thus stimulate producers to make more of what people want. Pricing in a pandemic is complicated and fraught. The policy puzzle involves balancing lower prices to ensure access to essential medications, vaccines, and tests against the need for adequate revenue streams to provide manufacturers with incentives to make the substantial, risky investments needed to develop products in the first place. We review alternative pricing strategies (cost recovery models, monetary prizes, and advance market commitments) for coronavirus disease 2019 (COVID-19) drugs, vaccines, and diagnostics. Hybrid pricing strategies are undoubtedly needed in a pandemic, but even in a public health crisis, value-based pricing is important. Cost-effectiveness analyses can inform pricing. Ideally, analyses would be conducted from both a health system and a societal perspective. Incorporating the added value of social benefits into cost-effectiveness analyses does not mean that manufacturers should capture the entire societal benefit of a diagnostic, vaccine, or therapy. read more Such analyses can provide important information and help policy makers consider the full costs and benefits of products and the wide-ranging ramifications of their actions.Empirical evidence has shown that peer pressure can impact human risk-taking behavior. With robots becoming ever more present in a range of human settings, it is crucial to examine whether robots can have a similar impact. Using the balloon analogue risk task (BART), participants' risk-taking behavior was measured when alone, in the presence of a silent robot, or in the presence of a robot that actively encouraged risk-taking behavior. In the BART, shown to be a proxy for real risk-taking behavior, participants must weigh risk against potential payout. Our results reveal that participants who were encouraged by the robot did take more risks, while the mere presence of the robot in the robot control condition did not entice participants to show more risk-taking behavior. Our results point to both possible benefits and perils that robots might pose to human decision-making. Although increasing risk-taking behavior in some cases has obvious advantages, it could also have detrimental consequences that are only now starting to emerge.Eye blinks strongly attenuate visual input, yet we perceive the world as continuous. How this visual continuity is achieved remains a fundamental and unsolved problem. A decrease in luminance sensitivity has been proposed as a mechanism but is insufficient to mask the even larger decrease in luminance because of blinks. Here we put forward a different hypothesis visual continuity can be achieved through shortening of perceived durations of the sensory consequences of blinks. Here we probed the perceived durations of the blackouts caused by blinks and visual stimuli interrupted by blinks. We found that the perceived durations of blackouts because of blinks are about half as long as artificial blackouts immediately preceding or following the blink. Stimuli interrupted by blinks were perceived as briefer than uninterrupted stimuli, by about the same duration as the interruption-but so were stimuli interrupted by optically simulated blinks. There was a difference between real and simulated blinks, however The decrease in perceived duration depended on the duration of the interruption for simulated, but not for real, blinks. These profound modifications in time perception during blinks show a way in which temporal processing contributes to the solution of an essential perceptual problem.

As evidence, according to Google Scholar (as of August 17, 2020), this article has been cited 3,391 times. Writing about recognition memory, Mandler made a fundamental distinction between recognition involving familiarity and recognition involving recollection. Mandler introduced what has since become the label for his illustration, saying that "Specific identification of an event is not possible on the basis of its familiarity alone. The butcher-in-the-bus is one intuitive demonstration of such an assertion." The purpose of this note is, ironically, to provide context, in this case historical context. Twenty-seven years before Mandler's (1980) article, Charles Osgood (1953) provided a discussion of retention and interference theory in his book, Method and Theory in Experimental Psychology. Is it possible that Mandler inadvertently borrowed Osgood's illustration, a case of cryptomnesia?

However, these measures cannot elucidate implicit processes that are equally important, as they guide the perceptions of the self and influence behavioral responses. Thus, we aimed to extend the research on SCE in BPD utilizing an indirect latency-based measure. A total of 29 female inpatients with BPD and 21 healthy women were assessed with a shame and a guilt self-concept Implicit Association Test (IAT). These two tasks use reaction time measurements to determine the relative strengths of associations between the self versus others and shame versus pride and guilt versus innocence. In addition, participants completed questionnaires capturing shame, guilt, and BPD symptoms. Women with BPD displayed significantly more shame- and guilt-prone implicit self-concepts than the control group (d = 1.2 and d = 0.7, respectively). They also scored significantly higher on explicit measures of shame and guilt. Although explicitly and implicitly assessed shame and guilt were strongly associated with borderline pathology, multivariate models indicated that solely self-reported, but not implicitly measured, guilt was consistently related to all BPD outcomes. Shame was only associated with the number of BPD criteria. This study extends previous findings on SCE in BPD, in that women with BPD do not only explicitly conceive themselves as more shame- and guilt-prone but also exhibit implicitly more shame and guilt self-concepts than healthy controls. Our results may hold clinical and therapeutic implications. (PsycInfo Database Record (c) 2020 APA, all rights reserved).Individuals with bulimia nervosa often experience suicidal ideation. Identity disturbance, or unstable sense of self, has been connected both to eating disorders and to suicidality. This study sought to test whether identity problems were related to severity of current suicidal ideation in a sample of women with bulimic-spectrum pathology, above and beyond history of suicidal behavior and several symptoms of borderline personality disorder. Women (N = 204; 90.7% Caucasian; Mage = 25.7 years [SD = 8.8]) with bulimic-spectrum pathology completed self-report personality assessments and items evaluating suicidality. A hierarchical linear regression was utilized to examine the association between identity problems and severity of current suicidal ideation, before and after inclusion of relevant clinical features (i.e., suicide attempt history [Step 2], affective lability, stimulus seeking, and rejection [Step 3]). Identity problems were directly associated with severity of current suicidal ideation (β = .481, p less then .
