Reconstructing the lifetime movements of ancient people: a Neolithic case study from southern England

A new procedure is described in which combined lead and strontium isotope analysis of archaeological human dental tissues can be used to comment on the lifetime movements of individuals. A case study is presented of four Neolithic burials – an adult female and three juveniles – from a shared burial pit excavated at Monkton-up-Wimbourne, Dorset. It is demonstrated that the adult's place of origin was at least 80km to the north-west in the area of the Mendips. It is also shown that all three juveniles moved over significant distances during their lives

The Arabian Leopard (Panthera pardus nimr) conservation breeding program.

Abstract. Captive breeding has the potential to play a pivotal role in conserving threatened species, among others by providing a healthy "safety net" population with which to buffer dwindling numbers in the wild. The Arabian Leopard Panthera pardus nimr is Critically Endangered on the IUCN Red List. Captive breeding is an essential component of conservation for this species. Many experts are of the opinion that the chances for survival of the Arabian Leopard in the wild are much reduced without the potential for reintroduction of animals. The captive breeding programme has been operating on a regional level since 1999, although the first Arabian Leopards registered in the studbook were caught in 1985. The current living population consists of 42 males, 32 females, and three unsexed leopards; nineteen are wild caught (of which 3 are siblings) and a substantial number of these do not actively participate in the breeding programme. The program focuses on ensuring a genetically sound population that closely resembles the wild population. Current and predicted trends within the population are compared with recommended trends and graphically illustrated using dedicated population management software, PM2000

Did I say dog or cat? A study of semantic error detection and correction in children

Although naturalistic studies of spontaneous speech suggest that young children can monitor their speech, the mechanisms for detection and correction of speech errors in children are not well understood. In particular, there is little research on monitoring semantic errors in this population. This study provides a systematic investigation of detection and correction of semantic errors in children between the ages of 5 and 8 years as they produced sentences to describe simple visual events involving nine highly familiar animals (the moving animals task). Results showed that older children made fewer errors and corrected a larger proportion of the errors that they made than younger children. We then tested the prediction of a production-based account of error monitoring that the strength of the language production system, and specifically its semantic–lexical component, should be correlated with the ability to detect and repair semantic errors. Strength of semantic–lexical mapping, as well as lexical–phonological mapping, was estimated individually for children by fitting their error patterns, obtained from an independent picture-naming task, to a computational model of language production. Children’s picture-naming performance was predictive of their ability to monitor their semantic errors above and beyond age. This relationship was specific to the strength of the semantic–lexical part of the system, as predicted by the production-based monitor

Associate Psychological Practitioners (APPs) in Primary Care: Modelling the Impact

Background: The ‘Associate Psychological Practitioner’ (APP) is an innovative new role that expands the psychological workforce and addresses the rising demand for mental health services in England, yet the impact of this role on NHS workforce capacity has yet to be modelled. Aim: We modelled the impact of the APP role in Primary Care in terms of additional capacity to provide mental health care and the impact on General Practitioner (GP) capacity within the sector. Method: Workforce experts of the NHS Workforce Repository and Planning Tool (WRaPT) team used a modelling tool to determine future state scenarios of APPs working across all Primary Care Networks (PCNs) within a region, and the associated change on the baseline workforce. Modelling was based on Lancashire and South Cumbria, a large geographical area in North-West England that includes 41 PCNs. Assumptions used in the modelling included identifying the patient population and workforce in scope, documenting the activity undertaken by APPs, and considering the future state scenarios for modelling. Findings: With regards to generating additional capacity, having 1 APP in each of the 41 PCNs in Lancashire and South Cumbria could provide 53,000 brief intervention appointments of 45 minutes each, thereby diverting these appointments away from the GP; and up to 48 people could benefit from attending Group and Wellbeing sessions over a year with 1 APP working with another Primary Care colleague, that is, 384 group intervention sessions delivered. In relation to GP capacity, 1 APP (if placed across a PCN, or within multiple practices) could free up at least 1,665 General Practitioner appointments within one year, which could lead to potential cost savings. These findings can be used to underpin decision making in respect of training future cohorts of APPs and contribute to wider workforce planning in primary care

Can a new role, the (Trainee) Associate Psychological Practitioner (T/APP), add value in General Practice? Results from the pilot year evaluation.

The deployment of (Trainee) Associate Psychological Practitioners (T/APPs) to deliver brief psychological interventions focusing on preventing mental health deterioration and promoting emotional wellbeing in General Practice settings is a novel development in the North West of England. As the need and demand for psychological practitioners increases, new workforce supply routes are required to meet this growth. To evaluate the clinical impact and efficacy of the mental health prevention and promotion service, provided by the T/APPs and the acceptability of the role from the perspective of the workforce and the role to T/APPs, patients and services. A mixed-methods design was used. To evaluate clinical outcomes, patients completed measures of wellbeing (WEMWBS), depression (PHQ-9), anxiety (GAD-7) and resilience (BRS) at the first session, final session and at a 4-6 week follow-up. Paired-samples t-tests were conducted comparing scores from session 1 and session 4, and session 1 and follow-up for each of the four outcome measures. To evaluate acceptability, questionnaires were sent to General Practice staff, T/APPs and patients to gather qualitative and quantitative feedback on their views of the T/APP role. Quantitative responses were collated and summarised. Qualitative responses were analysed using inductive summative content analysis to identify themes. T-test analysis revealed clinically and statistically significant reductions in depression and anxiety and elevations in wellbeing and resiliency between session 1 and session 4, and at follow-up. Moderate-large effect sizes were recorded. Acceptability of the T/APP role was established across General Practice staff, T/APPs and patients. Content analysis revealed two main themes: positive feedback and constructive feedback. Positive sub-themes included accessibility of support, type of support, patient benefit and primary care network benefit. Constructive sub-themes included integration of the role and limitations to the support. The introduction of T/APPs into General Practice settings to deliver brief mental health prevention and promotion interventions is both clinically effective and acceptable to patients, General Practice staff and psychology graduates

Pilot trial of a type I - polarized autologous dendritic cell vaccine incorporating tumor blood vessel antigen-derived peptides in patients with metastatic breast cancer

Cancer vaccines based on tumor-associated antigens are rarely curative in advanced cancer. This limitation relates to the heterogeneity of cancer due to defects in antigen presentation and altered immunophenotypes. Therefore, another method to promote anti-tumor immunity is to prime T cells against tumor-associated stromal cells. We have reported [1] that IL-12 gene therapy of established HLA-A2neg B16 melanomas in HLA-A2+ transgenic mice resulted in CD8+ T cell-mediated immunity against the host HLA-A2+ stromal cells within the tumor microenvironment (TME). We have also shown [2] that vaccines based on a subset of tumor blood vessel antigen (TBVA)-derived peptides (DLK1, EphA2, HBB, NRP1, PDGFRβ, RGS5 or TEM1) prevented HLA-A2neg MC38 tumor establishment and promoted the regression of tumors in HLA-A2+ mice by CD8+ T cell targeting of HLA-A2+ pericytes and vascular endothelial cells in the TME. Based on this pre-clinical data, we propose to undertake a Susan G. Komen -funded (IIR13261822) clinical trial of chemo-immunotherapy using the immunomodulatory drug gemcitabine with a dendritic cell vaccine pulsed with six HLA-A2-presented TBVA-derived peptides (DLK1310-318, EphA2883-891, HBB31-39, NRP1433-441, RGS55-13 and TEM1691-700) in 30 HLA-A2+ patients with metastatic breast cancer. The specific aims of this study are to determine vaccine-induced generation of TBVA-Tc1 immunity and clinical response
