Errorful learning improves recognition memory for new vocabulary for people living with memory and dysexecutive impairment following brain injury

A widely accepted view is that errorless learning is essential for supporting new learning in people with anterograde amnesia, but findings are mixed for those with a broader range of memory impairments. People at a chronic stage of recovery from brain injury (BI) with impaired memory and executive function (N = 26) were compared with adults in a comparison group without any known risks to brain function (N = 25). Learning techniques were compared using a “Generate-and-correct” and “Read-only” condition when learning novel word pairs. At test, both groups scored above chance and showed benefits of Generate-and-correct (errorful learning). Poor learners in the BI group were classified from “flat” learning slopes extracted from an independent word-pair learning task. Critically, poor learners showed no benefit, but also no decrement to learning, using the Generate-and-correct method. No group was harmed by errorful learning; all, except the poorest learners, benefitted from errorful learning. This study indicates, that in some rehabilitation settings, encouraging clients to guess the meaning of unfamiliar material (e.g., from cards, magazines, newspapers) and then correct their errors, could have benefits for recognition memory. Determining when and how errorful learning benefits learning is a key aim for future research

Women’s experiences of early pregnancy loss services during the pandemic:A qualitative investigation

Problem: Early pregnancy losses [EPL] are common, varied, and require different courses of management and care. Background: In the UK, women who suspect or suffer a pregnancy loss are usually provided specialist care in early pregnancy assessment units [EPAUs]. Their configuration has recently been evaluated, but recommendations for change in-line with best practice for optimum outcomes were unable to be implemented due to the COVID-19 pandemic health system shock.Aim: To compare women’s experiences of EPAUs during the pandemic to themes previously found in qualitative work undertaken with women who utilised EPAUs before the pandemic.Methods: We conducted semi-structured virtual interviews, with women (N=32) who suffered an early pregnancy loss during the pandemic; analysing transcripts using Template Analysis, based on findings about women’s (pre-pandemic) experiences of EPAU from The VESPA Study.Findings: We report on seven key themes: Barriers to Accessing Services; Communication &amp; Information; Retention of Relational Care; Involvement in Care Decisions; Staffs’ Attitude or Approach; Efficiency of Service Delivery; Sensitive Patient Management. Discussion: Sensitive patient management and woman-staff interactions in EPAU settings remain a fundamental issue. Women also reported their experiences of EPAUs were comparatively worse during the pandemic.Conclusions: Women valued the care provided by EPAUs and found services to be efficient, despite pandemic-related restrictions. However, psychological recognition surrounding EPL and appropriate, sensitive, relational care and support continue to be areas in need of improvement. Our recommendation is to implement the improvements suggested by VESPA as a priority to ameliorate present sub-optimal experiences and prevent further deterioration.<br/

Monoclonal antibody levels and protection from COVID-19

Multiple monoclonal antibodies have been shown to be effective for both prophylaxis and therapy for SARS-CoV-2 infection. Here we aggregate data from randomized controlled trials assessing the use of monoclonal antibodies (mAb) in preventing symptomatic SARS-CoV-2 infection. We use data on the in vivo concentration of mAb and the associated protection from COVID-19 over time to model the dose-response relationship of mAb for prophylaxis. We estimate that 50% protection from COVID-19 is achieved with a mAb concentration of 96-fold of the in vitro IC50 (95% CI: 32—285). This relationship provides a tool for predicting the prophylactic efficacy of new mAb and against SARS-CoV-2 variants. Finally, we compare the relationship between neutralization titer and protection from COVID-19 after either mAb treatment or vaccination. We find no significant difference between the 50% protective titer for mAb and vaccination, although sample sizes limited the power to detect a difference

Crossing disciplines: do architecture and planning course leaders see value in a Public Health Practitioner in Residence programme?

Highlights• We study a public health residency in a university architecture and planning department.• We assess the benefits of the residency from the perspective of the teaching staff.• The residency was successful at introducing public health issues and concepts to students.• There appeared to be a gap in the staff's understanding of public health concerns

Mutation Rate Distribution Inferred from Coincident SNPs and Coincident Substitutions

Mutation rate variation has the potential to bias evolutionary inference, particularly when rates become much higher than the mean. We first confirm prior work that inferred the existence of cryptic, site-specific rate variation on the basis of coincident polymorphisms—sites that are segregating in both humans and chimpanzees. Then we extend this observation to a longer evolutionary timescale by identifying sites of coincident substitutions using four species. From these data, we develop analytic theory to infer the variance and skewness of the distribution of mutation rates. Even excluding CpG dinucleotides, we find a relatively large coefficient of variation and positive skew, which suggests that, although most sites in the genome have mutation rates near the mean, the distribution contains a long right-hand tail with a small number of sites having high mutation rates. At least for primates, these quickly mutating sites are few enough that the infinite sites model in population genetics remains appropriate

High levels of population genetic differentiation in the American crocodile (Crocodylus acutus)

The American crocodile (Crocodylus acutus) is a widely distributed species across coastal and brackish areas of the Neotropical region of the Americas and the Greater Antilles. Available information on patterns of genetic differentiation in C. acutus shows a complex structuring influenced by interspecific interactions (mainly hybridization) and anthropogenic actions (mostly historical hunting, recent poaching, habitat loss and fragmentation, and unintentional translocation of individuals). In this study, we used data on mitochondrial DNA control region and 11 nuclear polymorphic microsatellite loci to assess the degree of population structure of C. acutus in South America, North America, Central America and the Greater Antilles. We used traditional genetic differentiation indices, Bayesian clustering and multivariate methods to create a more comprehensive picture of the genetic relationships within the species across its range. Analyses of mtDNA and microsatellite loci show evidence of a strong population genetic structure in the American crocodile, with unique populations in each sampling locality. Our results support previous findings showing large degrees of genetic differentiation between the continental and the Greater Antillean C. acutus. We report three new haplotypes unique to Venezuela, which are considerably less distant from the Central and North American haplotypes than to the Greater Antillean ones. Our findings reveal genetic population differentiation between Cuban and Jamaican C. acutus and offer the first evidence of strong genetic differentiation among the populations of Greater Antillean C. acutus

Extinction risk and conservation of the world\u27s sharks and rays

The rapid expansion of human activities threatens ocean-wide biodiversity. Numerous marine animal populations have declined, yet it remains unclear whether these trends are symptomatic of a chronic accumulation of global marine extinction risk. We present the first systematic analysis of threat for a globally distributed lineage of 1,041 chondrichthyan fishes&mdash;sharks, rays, and chimaeras. We estimate that one-quarter are threatened according to IUCN Red List criteria due to overfishing (targeted and incidental). Large-bodied, shallow-water species are at greatest risk and five out of the seven most threatened families are rays. Overall chondrichthyan extinction risk is substantially higher than for most other vertebrates, and only one-third of species are considered safe. Population depletion has occurred throughout the world&rsquo;s ice-free waters, but is particularly prevalent in the Indo-Pacific Biodiversity Triangle and Mediterranean Sea. Improved management of fisheries and trade is urgently needed to avoid extinctions and promote population recovery
