A mixed method study into obstetric sonographer-led-discharge and other forms of sonographer role extension

INTRODUCTION: Sonographer-led-discharge was proposed in a maternity unit to provide a holistic service, cut waiting times, ease staffing pressures and increase job satisfaction. This study explored sonographers’ experiences and perspectives of this new extended role and other areas of non-obstetric role extension. Understanding these will inform future practice and the success of the proposed obstetric sonographer-led-discharge and career structure. METHODS: A mixed methodology, cross-sectional study was performed, with a purposive, non-probability sample using an online data collection tool. The data were analysed using descriptive statistics and thematic analysis. RESULTS: In total, 93 sonographers participated in the study. Of these, 25% of sonographers currently practising obstetric ultrasound said they would not undertake the proposed obstetric sonographer-led-discharge role extension although 90% of the participants said role extension provides job satisfaction. Several themes emerged from the data, including job satisfaction, benefits to the hospital, improved patient pathway, time, personal factors, litigation and intra- and interprofessional resistance. A total of 54% of staff currently performing a role extension have experienced either inter- or intraprofessional conflict and only 48.5% said their workload was manageable. CONCLUSIONS: The data collected suggested that, with training and support, the proposed obstetric sonographer-led-discharge role is an appropriate role extension for sonographers. These findings support the premise of the proposed sonographic career structure, although the inter- and intraprofessional resistance identified in the study could form a significant barrier if it is not appropriately considered and managed

Potential for Forecasting UK Summer Grass Growth from the North Atlantic Oscillation

The North Atlantic Oscillation (NAO) is a large-scale atmospheric circulation pattern which is well-known to influence the UK winter climate (Wilby et al., 1997). Recently, it has been shown that the winter NAO also affects summer rainfall in the UK (Kettlewell et al., 2003). Since water supply is an important limitation to summer grass growth in many parts of the UK, the winter NAO may influence summer growth. The objective of this study was to test the hypothesis that there is a relationship between the winter NAO and summer grass growth using data from reference plots at North Wyke in Devon

A study of mapping usual care and unmet need for vocational rehabilitation and psychological support following major trauma in five health districts in the UK

Objective: Traumatic injuries are common in working age adults. Survivors may experience physical and psychological problems that affect their ability to work. Rehabilitation pathways are complex, and it is unclear whether adequate vocational/psychological support exists post-injury. Aim: To understand where and how trauma survivors' rehabilitation needs are met post-trauma, and map rehabilitation across five UK major trauma networks. Design: Qualitative study (interviews, focus groups, workshops) using soft-systems methodology to map usual care across trauma networks and explore service gaps. Publicly available documents were consulted. CATWOE (Customers, Actors, Transformation, Worldview, Owners, Environment) was used as an analytic thematic framework to explore the relationship between stakeholders in the pathway. Setting: Five major trauma networks across the UK. Subjects: 106 key rehabilitation stakeholders (service providers, trauma survivors) were recruited to interviews (n=46), focus groups (n=4 groups, 17 participants) and workshops (n=5 workshops, 43 participants). Interventions: None. Results: Mapping of rehabilitation pathways identified several issues: 1) lack of vocational/psychological support particularly for musculoskeletal injuries; 2) inconsistent service provision in areas located further from major trauma centres; 3) lack of communication between acute and community care; 4) long waiting lists (up to 12 months) for community rehabilitation; 5) most well-established pathways were neurologically focused. Conclusions: The trauma rehabilitation pathway is complex and varies across the UK with few, if any patients following an 'ideal' pathway. Services have developed piecemeal to address specific issues, but rarely meet the needs of individuals with multiple impairments post-trauma, with a lack of vocational rehabilitation and psychological support for this population

Vocational rehabilitation to enhance return to work after trauma (ROWTATE): protocol for a non-randomised single arm mixed-methods feasibility study

Background: Traumatic injuries are common amongst working-age adults. Survivors often experience physical and psychological problems, reduced quality of life and difficulty returning to work. Vocational rehabilitation improves work outcomes for a range of conditions but evidence of effectiveness for those with traumatic injuries is lacking. This study assesses feasibility of delivering a vocational rehabilitation intervention to enhance return to work and improve quality of life and wellbeing in people with at least moderate trauma to inform design of a definitive randomised controlled trial (RCT). Methods: Non-randomised, single-arm, multi-centre mixed-methods feasibility study with nested case studies and qualitative study. The case studies comprise interviews, observations of clinical contacts and review of clinical records. The qualitative study comprises interviews and/or focus groups. Participants will be recruited from two UK major trauma centres. Participants will comprise 40 patients aged 16–69 with an injury severity score of > 8 who will receive the intervention and complete questionnaires. Interviews will be conducted with 10 patients and their occupational therapists (OTs), clinical psychologists (CPs), employers and commissioners of rehabilitation services. Fidelity will be assessed in up to six patients by observations of OT and CP—patient contacts, review of patient records and intervention case report forms. OT and CP training will be evaluated using questionnaires and competence to deliver the intervention assessed using a team objective structured clinical examination and written task. Patients participating in and those declining participation in the study will be invited to take part in interviews/focus groups to explore barriers and facilitators to recruitment and retention. Outcomes include recruitment and retention rates, intervention fidelity, OT and CP competence to deliver the intervention, experiences of delivering or receiving the intervention and factors likely to influence definitive trial delivery. Discussion: Effective vocational rehabilitation interventions to enhance return to work amongst trauma patients are urgently needed because return to work is often delayed, with detrimental effects on health, financial stability, healthcare resource use and wider society. This protocol describes a feasibility study delivering a complex intervention to enhance return to work in those with at least moderate trauma

Pigmentation plasticity enhances crypsis in larval newts: Associated metabolic cost and background choice behaviour

In heterogeneous environments, the capacity for colour change can be a valuable adaptation enhancing crypsis against predators. Alternatively, organisms might achieve concealment by evolving preferences for backgrounds that match their visual traits, thus avoiding the costs of plasticity. Here we examined the degree of plasticity in pigmentation of newt larvae (Lissotriton boscai) in relation to predation risk. Furthermore, we tested for associated metabolic costs and pigmentation-dependent background choice behaviour. Newt larvae expressed substantial changes in pigmentation so that light, high-reflecting environment induced depigmentation whereas dark, low-reflecting environment induced pigmentation in just three days of exposure. Induced pigmentation was completely reversible upon switching microhabitats. Predator cues, however, did not enhance cryptic phenotypes, suggesting that environmental albedo induces changes in pigmentation improving concealment regardless of the perceived predation risk. Metabolic rate was higher in heavily pigmented individuals from dark environments, indicating a high energetic requirement of pigmentation that could impose a constraint to larval camouflage in dim habitats. Finally, we found partial evidence for larvae selecting backgrounds matching their induced phenotypes. However, in the presence of predator cues, larvae increased the time spent in light environments, which may reflect a escape response towards shallow waters rather than an attempt at increasing crypsisFinancial support was provided by the Spanish Ministry of Science and Innovation (MICINN), Grant CGL2012-40044 to IGM, and by the Universidad Autónoma de Madrid, Short Stay Grant to NPC.

S100A1: A Multifaceted Therapeutic Target in Cardiovascular Disease

Cardiovascular disease is the leading cause of death worldwide, showing a dramatically growing prevalence. It is still associated with a poor clinical prognosis, indicating insufficient long-term treatment success of currently available therapeutic strategies. Investigations of the pathomechanisms underlying cardiovascular disorders uncovered the Ca2+ binding protein S100A1 as a critical regulator of both cardiac performance and vascular biology. In cardiomyocytes, S100A1 was found to interact with both the sarcoplasmic reticulum ATPase (SERCA2a) and the ryanodine receptor 2 (RyR2), resulting in substantially improved Ca2+ handling and contractile performance. Additionally, S100A1 has been described to target the cardiac sarcomere and mitochondria, leading to reduced pre-contractile passive tension as well as enhanced oxidative energy generation. In endothelial cells, molecular analyses revealed a stimulatory effect of S100A1 on endothelial NO production by increasing endothelial nitric oxide synthase activity. Emphasizing the pathophysiological relevance of S100A1, myocardial infarction in S100A1 knockout mice resulted in accelerated transition towards heart failure and excessive mortality in comparison with wild-type controls. Mice lacking S100A1 furthermore displayed significantly elevated blood pressure values with abrogated responsiveness to bradykinin. On the other hand, numerous studies in small and large animal heart failure models showed that S100A1 overexpression results in reversed maladaptive myocardial remodeling, long-term rescue of contractile performance, and superior survival in response to myocardial infarction, indicating the potential of S100A1-based therapeutic interventions. In summary, elaborate basic and translational research established S100A1 as a multifaceted therapeutic target in cardiovascular disease, providing a promising novel therapeutic strategy to future cardiologists
