'We just need to find space for them to practice so that we can help to make a stronger society': Perceived barriers and facilitators to employing health psychologists in UK public health and clinical health settings.

INTRODUCTION: In recent years, health psychology has received significant attention within the health sector, due to its application to understanding influences on health and well-being and translation of health psychology into interventions to support behaviour change. The number of health psychologists in public health and healthcare settings is growing but remains limited, and is it unclear why. This study aimed to explore the views of potential and current employers of health psychologists, to elucidate barriers and facilitators of employing health psychologists in healthcare settings. METHODS: Semi-structured interviews were carried out to explore the experiences of working with and/or employing health psychologists. Opportunities and barriers were explored for increasing access to health psychology expertise in the NHS and public health. Interviews were analysed using inductive thematic analysis. RESULTS: Fifteen participants took part in interviews. Participants were mid-senior-level professionals working in varied healthcare settings and/or academic institutions. The majority had experience of health psychology/working with health psychologists, whilst others had limited experience but an interest in employing health psychologists. Three key themes were identified: (1) the organizational fit of health psychologists, (2) perception of competition for roles and (3) ideas for changing hearts, minds and processes. CONCLUSION: Barriers exist to employing health psychologists in healthcare settings. These barriers include misunderstandings of the role of health psychologists and the need to preserve other disciplines due to perceived competition. Recommendations for change included showcasing the benefits and skills of health psychologists and having transparent conversations with employees and multi-disciplinary colleagues about roles.

Using behavioural science in public health settings during the COVID-19 pandemic: The experience of public health practitioners and behavioural scientists.

INTRODUCTION: The emergence of COVID-19 and the importance of behaviour change to limit its spread created an urgent need to apply behavioural science to public health. Knowledge mobilisation, the processes whereby research leads to useful findings that are implemented to affect positive outcomes, is a goal for researchers, policy makers and practitioners alike. This study aimed to explores the experience of using behavioural science in public health during COVID-19, to discover barriers and facilitators and whether the rapidly changing context of COVID-19 influenced knowledge mobilisation. METHODS: We conducted a semi-structured interview study, with ten behavioural scientists and seven public health professionals in England, Scotland, Wales, The Netherlands and Canada. We conducted an inductive thematic analysis. RESULTS: We report three key themes and 10 sub-themes: 1.Challenges and facilitators of translation of behavioural science into public health (Methods and frameworks supported translation, Lack of supportive infrastructure, Conviction and sourcing of evidence and Embracing behavioural science) 2. The unique context of translation (Rapid change in context, the multi-disciplinary team and the emotional toll). 3. Recommendations to support future behavioural science translation (Embedding experts into teams, Importance of a collaborative network and showcasing the role of behavioural science). DISCUSSION: Barriers and facilitators included factors related to relationships between people, such as networks and teams; the expertise of individual people; and those related to materials, such as the use of frameworks and an overwhelming amount of evidence and literature. CONCLUSION: People and frameworks were seen as important in facilitating behavioural science in practice. Future research could explore how different frameworks are used. We recommend a stepped competency framework for behavioural science in public health and more focus on nurturing networks to facilitate knowledge mobilisation in future emergencies.

Construction of a conceptual framework for assessment of health-related quality of life in calves with respiratory disease.

Bovine respiratory disease (BRD) is one of the most prevalent diseases affecting beef and dairy calves worldwide, with implications for lifetime productivity, antimicrobial use and animal welfare. Our objective was to construct a conceptual framework for assessment of health-related quality of life (HRQL) in calves with respiratory disease, based on indicators suitable for direct pen-side visual observation. Health-related quality of life measures aim to evaluate the subjective experience of the animal rather than any related pathology. A conceptual framework graphically represents the concepts to be measured and the potential relationships between them. A multistage, mixed method approach involving diverse data sources, collection methods and stakeholders was applied to promote comprehensiveness, understanding and validity of findings. A scoping review was conducted to identify, characterize and collate evidence of behavioural indicators of BRD. The indicators identified were mapped against the principal attributes of five prominent animal welfare assessment frameworks to appraise their correspondence with different characterizations of the dimensions of welfare. Forty-two semi-structured, individual, qualitative interviews with a purposeful sample of experienced veterinarians and stockpersons from UK, USA and Canada elicited in-depth descriptions of the visual observations of HRQL they make in diagnosing and assessing the response to treatment of calves with BRD. Verbatim interview transcripts were examined using inductive thematic analysis. Respondents provided insights and understanding of indicators of HRQL in BRD such as interaction with feed source, hair coat condition, specific characteristics of eye appearance, eye contact, rumen fill and stretching (pandiculation). In an on-farm pilot study to assess the value of potential HRQL behavioural indicators, there was a moderate positive correlation between behaviour and clinical scores (rs = 0.59) across the 5 days preceding veterinary treatment for BRD. Interestingly, the behaviours evaluated were observed a median of 1.0 (interquartile range: 1.0-3.5) days before clinical indicators used in the scoring system. The proposed conceptual framework for assessment of HRQL features 23 putative indicators of HRQL distributed across two interrelated domains - clinical signs and behavioural expressions of emotional well-being. It has potential applications to inform the development of new HRQL measures such as structured questionnaires and automated sensor technologies.

Water quality impact from shrimp farming effluents in a tropical estuary.

Shrimp farms cause environmental impacts in coastal ecosystems, compromising water quality by discharging effluents rich in nutrients and organic matter. The impacts of shrimp farming are often investigated by the unit effect of a farm. In this study, a harvest time series generator is used to analyze the impact of the synergistic effect of several shrimp farm harvests in a tropical estuary. Two other scenarios with harvests concentrated during spring and neap tides were also analyzed, showing waste management techniques that can reduce the impact of shrimp aquaculture on coastal areas. A hydrodynamic circulation and water quality model were implemented to evaluate the dispersion of pollutants using different discharge combinations. The harvesting scenarios were compared to a scenario without the activity. Results indicate that shrimp farming is not the main anthropogenic source of pollution in the estuary studied. There were no significant differences in the average and maximum variations in nutrient and organic matter concentrations between the different management techniques.

How do members of a fire and rescue service perceive expanding their roles to deliver more health care services?

BACKGROUND: Increasingly, public sector workers are being required to expand their roles into public health. Fire and rescue services, as part of the Emergency Medical Response trial, are at the forefront of role expansion, with increasing capacity due to reducing numbers of fires in recent years. Firefighter roles, successfully implemented, include responding to cardiac arrests and conducting checks on health and wellbeing in people's own homes. In this study, we explored fire service members' perceptions about this role expansion, to increase understanding of how role expansion can be introduced and supported. METHODS: We interviewed 21 firefighters and team members about their perceptions of new roles. Interviews were conducted, transcribed and thematically analysed until reaching thematic saturation. RESULTS: Perspectives differed for responding to cardiac arrests and wellbeing checks. Cardiac arrests were seen as aligned with core roles and thus more acceptable. For both types of new role participants wanted more training and opportunities to provide feedback on implementation. CONCLUSIONS: How team members viewed role expansion depended on new role alignment with core role, training and being able to give feedback to management to shape future services.

Exploring psychosocial predictors of STI testing in University students.

BACKGROUND: To explore university students' Sexually Transmitted Infection (STI) testing knowledge, psychosocial and demographic predictors of past STI testing behaviour, intentions to have an STI test, and high risk sexual behaviour, to inform interventions promoting STI testing in this population. METHODS: A cross-sectional, quantitative online survey was conducted in March 2016, recruiting university students from North East Scotland via an all-student email. The anonymous questionnaire assessed student demographics (e.g. sex, ethnicity, age), STI testing behaviours, sexual risk behaviours, knowledge and five psychological constructs thought to be predictive of STI testing from theory and past research: attitudes, perceived susceptibility to STIs, social norms, social fear and self-efficacy. RESULTS: The sample contained 1294 sexually active students (response rate 10%) aged 18-63, mean age = 23.61 (SD 6.39), 888 (69%) were female. Amongst participants, knowledge of STIs and testing was relatively high, and students held generally favourable attitudes. 52% reported ever having an STI test, 13% intended to have one in the next month; 16% reported unprotected sex with more than one 'casual' partner in the last six months. Being female, older, a postgraduate, longer UK residence, STI knowledge, perceived susceptibility, subjective norms, attitudes and self-efficacy all positively predicted past STI testing behaviour (p < 0.01). Perceived susceptibility to STIs and social norms positively predicted intentions to have an STI test in the next month (p < 0.05); perceived susceptibility also predicted past high-risk sexual behaviour (p < 0.01). CONCLUSIONS: Several psychosocial predictors of past STI testing, of high-risk sexual behaviour and future STI intentions were identified. Health promotion STI testing interventions could focus on male students and target knowledge, attitude change, and increasing perceived susceptibility to STIs, social norms and self-efficacy towards STI-testing.

Reduced social interaction following 3,4-methylenedioxymethamphetamine is not associated with enhanced 5-HT 2C receptor responsivity.

This study examined the long-term change in serotonergic (5-hydroxytryptamine, 5-HT) neuronal function and 5-HT(2C) receptor agonist-induced behaviour following treatment of young rats with 3,4-methylenedioxymethamphetamine (MDMA). On post-natal day (PND) 28, Lister-hooded rats received either MDMA (15 mg/kg i.p.) or saline (1 ml/kg i.p.) twice daily for 3 days. On PND 50 social interaction was assessed between treatment-matched pairs of rats derived from separate litters. The effect of either the 5-HT(2C) receptor agonist, m-chlorophenylpiperazine (m-CPP, 2.5 or 1 mg/kg i.p., respectively) or saline was examined on open-field exploration (PND 52) and elevated plus-maze behaviour (PND 56). Acutely, MDMA produced hyperlocomotion and hypothermia compared with saline injection (p<0.001). Following 20 days abstinence, social interaction was decreased by 26% (p<0.05) in MDMA pre-treated rats compared with saline controls, without any change in locomotion. There was no difference in open-field or elevated plus-maze behaviour between pre-treatment groups. m-CPP caused hypolocomotion in the open-field and decreased both the percentage entries into, and time spent in, the open arms of the elevated plus-maze to a comparable extent in MDMA and saline pre-treated rats. Hippocampal and frontal cortical 5-HT and 5-hydroxyindoleacetic acid (5-HIAA) were significantly reduced in MDMA pre-treated rats, without any change in [(3)H]paroxetine binding or plasma corticosterone levels. These data suggest that the MDMA-induced reduction in social interaction is not mediated via alteration of 5-HT(2C) receptor function.

Enzymatic mutation detection (EMD) of novel mutations (R565X and R1523X) in the FBN1 gene of patients with Marfan syndrome using T4 endonuclease VII.

The Enzymatic Mutation Detection (EMDtrade mark) method is a streamlined and improved version of the original Enzymatic Cleavage of Mismatch (EMC) method. EMD is a fully homogeneous, rapid four step procedure that allows for detection and localization of mismatched or unmatched nucleotides within heteroduplex DNA. To test the utility of EMD for use in the screening of large and complex genes, the fibrillin 1 (FBN1) gene was scanned in a cohort of six patients diagnosed with connective tissue disorders. Four of the six patients were diagnosed with classic Marfan syndrome (MFS). The results were compared with a previous MDEtrade mark scanning of the same patient cohort. Two causative mutations, R565X and R1523X, were detected by EMD that were not detected by MDE. In both cases, the mutation resulted in premature termination of translation. In addition, several polymorphisms were detected by the enzymatic approach that failed detection by heteroduplex analysis. We propose that the EMD method is a sensitive and rapid approach to mutation detection in large genes such as FBN1.

Evaluation of the spontaneously hypertensive rat as a model of attention deficit hyperactivity disorder: acquisition and performance of the DRL-60s test.

CD. However, the pattern of responding at DRL-60s suggested poor schedule control for the WKY rats. Therefore, the performance of SHR in the DRL test does not appear to represent a valid model of ADHD. Further, our findings with the WKY rat suggest that this strain is a poor behavioural control for the SHR.

Multiple molecular mechanisms underlying subdiagnostic variants of Marfan syndrome.

Mutations in the FBN1 gene, which encodes fibrillin-1, cause Marfan syndrome (MFS) and have been associated with a wide range of milder, overlap phenotypes. The factors that modulate phenotypic severity, both between and within families, remain to be determined. This study examines the relationship between the FBN1 genotype and phenotype in families with extremely mild phenotypes and in those that show striking clinical variation among apparently affected individuals. In one family, clinically similar but etiologically distinct disorders are segregating independently. In another, somatic mosaicism for a mutant FBN1 allele is associated with subdiagnostic manifestations, whereas germ-line transmission of the identical mutation causes severe and rapidly progressive disease. A third family cosegregates mild mitral valve prolapse syndrome with a mutation in FBN1 that can be functionally distinguished from those associated with the classic MFS phenotype. These data have immediate relevance for the diagnostic and prognostic counseling of patients and their family members.

mdm2-P2 transcript levels predict the functional activity of the p53 tumor suppressor in primary leukemic cells.

The mdm2-P2 promoter is a transcriptional target of the p53 tumor suppressor. The aim of this study was to determine if there is an association between the level of these transcripts and the status of the p53 gene in human leukemic cells. A correlation between mdm2-P2 transcript levels and p53 gene status was observed in all cell lines examined. Primary malignant cells from 10 leukemic patients were also analysed for both mdm2-P2 levels and p53 gene status. All five patients with detectable mdm2-P2 transcripts possessed wild-type p53 alleles. However, only two of five patients with undetectable mdm2-P2 transcripts possessed mutant p53. mdm2-P2 levels were also determined in primary leukemic cells from 14 additional cases both before and after in vitro exposure to cisplatin. The p53 gene was found to be wild-type in all cases where mdm2-P2 levels were induced by cisplatin. There were four cases where no, or only modest, increases in mdm2-P2 levels were detected after cisplatin exposure. Two of these patients were found to harbor mutant p53 while one other possessed leukemic cells with elevated levels of mdm2 protein. These results show that induction of mdm2-P2 transcripts can be used to predict the presence of transcriptionally active p53 in primary leukemic cells.

Fifteen novel FBN1 mutations causing Marfan syndrome detected by heteroduplex analysis of genomic amplicons.

Mutations in the gene encoding fibrillin-1 (FBN1), a component of the extracellular microfibril, cause the Marfan syndrome (MFS). This statement is supported by the observations that the classic Marfan phenotype cosegregates with intragenic and/or flanking marker alleles in all families tested and that a significant number of FBN1 mutations have been identified in affected individuals. We have now devised a method to screen the entire coding sequence and flanking splice junctions of FBN1. On completion for a panel of nine probands with classic MFS, six new mutations were identified that accounted for disease in seven (78%) of nine patients. Nine additional new mutations have been characterized in the early stages of a larger screening project. These 15 mutations were equally distributed throughout the gene and, with one exception, were specific to single families. One-third of mutations created premature termination codons, and 6 of 15 substituted residues with putative significance for calcium binding to epidermal growth factor (EGF)-like domains. Mutations causing severe and rapidly progressive disease that presents in the neonatal period can occur in a larger region of the gene than previously demonstrated, and the nature of the mutation is as important a determinant as its location, in predisposing to this phenotype.

Single-blind, randomised, parallel group study of the Bard Biocath catheter and a silicone elastomer coated catheter.

A group of 69 community patients undergoing long-term urethral catheterisation for urinary incontinence took part in this study; 33 patients with a mean age of 70.03 years (+/- 16.6) received the Dow Corning Silastic catheter (16 F 10-ml balloon) and 36 patients with a mean age of 75.61 years (+/- 12.6) received the Bard Biocath catheter (16 F 10-ml balloon). Over a 16-week period catheters were monitored every 2 weeks and changed as necessary. The Bard Biocath catheter remained in situ for an average of 89.61 days (+/- 35.31) and the Silastic catheter remained in situ for an average of 56.7 days (+/- 38.8); this difference was statistically significant. Used catheters were analysed for encrustation using scanning electron microscopy (SEM). The average time in situ for non-encrusted Biocath catheters was 83.7 days and 25.28 days for non-encrusted Silastic catheters. It was found that 70% of patients who received Biocath catheters preferred them to their previous catheters whereas only 30% of patients in the Silastic group preferred the trial catheter. The incidence of bypassing was 28% in the Biocath group and 52.8% in the Silastic group.
