Neuropeptide Y is a 36 amino acid peptide that belongs to the pancreatic polypeptide family. It co-localises with adrenaline in sympathetic nerves and is released upon sympathetic activation resulting in vasoconstriction. In addition to its vascular effects NPY is also thought to have a role in pain modulation, angiogenesis and immunomodulation. Objectives: The aim of this study was to quantify the levels of NPY in human dental pulp tissue from intact and grossly carious teeth and to relate these results to pain experience. Methods: A total of 48 permanent teeth [mean age 32.1(+/- 11.2 years)] were included in the study, of these 22 were intact and 26 were grossly carious. In the grossly carious group, 17 teeth were reported painful prior to extraction and the remainder were reported non-painful. NPY was measured using a sensitive and specific radioimmunoassay which has been previously described. Pain was scored as either present or absent in all the teeth studied. Results: Of particular interest in this study was the finding that NPY levels were significantly higher in dental pulp tissue from non-painful grossly carious teeth (p= 0.006) compared with painful grossly carious teeth. Conclusions: The increased levels of NPY reported in non-painful grossly carious teeth may suggest a role for NPY in pain modulation in human dental pulp.

Introduction: Protease activated receptors (PARs) are G-protein-coupled transmembrane receptors that are expressed on many cell types and implicated in various inflammatory processes in vivo. The induction of PAR2 as a result of the inflammatory response associated with dental caries remains to be determined. Objectives: The aim was to localise the expression of PAR2 in human dental pulp from carious teeth and to confirm receptor functionality using an in vitro assay. Methods: Dental pulp sections from decalcified carious teeth were examined by immunocytochemsitry. Membrane preparations from cultured pulp fibroblasts were subject to SDS-PAGE and immunoblotting to confirm fibroblast-associated immunoreactivity. The functionality of PAR2 on dental pulp fibroblasts was studied using calcium imaging in the presence of several potential activators including a PAR2 agonist (PAR2-AP), trypsin and pulpal enzymes from a carious tooth. Results: Immunocytochemistry revealed intense PAR2 immunoreactivity on pulpal fibroblasts subjacent to carious lesions but not in surrounding regions of the dental pulp. Pulp specimens from a dental injury model showed no expression of PAR2, suggesting its expression was related to cellular changes associated with ongoing caries. The localisation of PAR2 staining to pulpal fibroblasts in carious teeth was confirmed by Western blotting which revealed PAR2 immunoreactive bands in membrane fractions prepared from pulp fibroblasts. In functional studies, challenge of cultured pupal fibroblasts with PAR2-AP, trypsin and an extract of proteolytic enzymes from a carious dental pulp, showed specific activation of PAR2. Conclusions: This work demonstrates that PAR2 is functional and inducible in human dental pulp fibroblasts in response to caries and that endogenous pulpal enzymes can activate PAR2.

This presentation aims to raise issues related to teenage relationship abuse (TRA-dating violence) and help seeking behaviour from an intersectional approach. Even though teenage relationship abuse has been raised as an issue since the 80’s there is still an absence of an intersectional theoretical conceptualization of TRA. Existing conceptualizations are based on incorrect assumptions of sameness of teenagers experiences of TRA which ignore the unique developmental stages of teenagers as well as youth’s diverse lived experiences due to their sexual orientation, ethnicity, class, disability as well as other structural divisions. TRA exists in a social context of inequalities. For the individual survivor, this social context is created not only through romantic relationships, but also through relationships with families, peers, friends, classmates and others. Their experiences are constructed through these relationships which form part of the social context into which TRA needs to be analysed. The analytical framework of intersectionality can provide a framework of understanding how these lived experiences are enacted and negotiated contextually. Emphasis will be given to the help seeking behaviour of diverse youths. This presentation will explore the diverse lived experiences contextually. Methods and Findings: This presentation is based on a research project in Northern Ireland currently underway, thus, it will offer a preliminary conceptualisation of TRA from an intersectional approach. The findings will be contextualized taking into account the high rate of homophobia that exists in Northern Ireland amongst other things. Conclusion/Recommendation: Intersectionality needs to be the analytical framework through which teenagers’ relationship’s experience are analysed since the lived experiences of LGTB, BME and disabled youth cannot be analysed apart from the structural divisions, social location and the context they are experienced. This presentation argues that the intersectional approach of theorizing is congruent and contributes to anti-oppressive social work practice.

Background: Cachexia has been defined as an on-going loss of skeletal muscle mass that cannot be fully reversed by conventional nutritional support. It can be found in up to 80% of patients with advanced cancer and has profound psycho-social consequences for patients and their families. There is a paucity of studies examining the role and experience of healthcare professionals in relation to cachexia and existing studies suggest that professional staff have limited understanding and do not intervene effectively.
Aim: To identify barriers and facilitators to good practice in cachexia care in order to inform future developments in service provision.
Design: An exploratory qualitative study was conducted employing semi-structured interviews with a range of healthcare professionals recruited purposefully from an Australian hospital. Interviews were conducted in private rooms within the hospital.
Setting/participants: A range of healthcare professionals responsible for cancer care were recruited from a large Australian teaching hospital.
Results: Interviews were conducted with 8 healthcare professionals responsible for delivering cancer care. Four themes were identified: formal and informal education, knowledge and understanding, truth telling in cachexia and palliative care, and, a multi-disciplinary approach. Findings show how improved knowledge and understanding across a staff body can lead to improved staff confidence and a willingness to address cancer cachexia and its consequences with patients and their families.
Conclusion: Comparison with previous studies illustrates the importance of improving knowledge and understanding about cachexia and how this can contribute to staff having the skills and experience necessary to address cachexia and provide an improved care experience for patients and carers.

Objective The aim of this study was to collate and compare data on the training of Specialty Registrars in Restorative Dentistry (StRs) in the management of head and neck cancer (HANC) patients across different training units within the UK and Ireland. Methods Current trainees were invited to complete an online questionnaire by the Specialty Registrars in Restorative Dentistry Group (SRRDG). Participants were asked to rate their confidence and experience of assessing and planning treatment for HANC patients, attending theatre alone and manufacturing surgical obturators, and providing implants for appropriate cases. Respondents were also asked to appraise clinical and didactic teaching at their unit, and to rate their confidence of passing a future Intercollegiate Specialty Fellowship Examination (ISFE)-station assessing knowledge of head and neck cancer. Results Responses were obtained from 21 StRs (n=21) training within all five countries of the British Isles. Most respondents were based in England (76%), with one StR in each of Scotland, Wales, Northern Ireland and the Republic of Ireland. A third (33%) were in their 5th year of training. Almost half of the StRs indicated that they were confident of independently assessing (48%) new patients with HANC, with fewer numbers reporting confidence in treatment planning (38%). The majority (52%) of respondents indicated that they were not confident of attending theatre alone and manufacturing a surgical obturator. A third (33%) rated their experience of treating HANC patients with implants as ‘poor’ or ‘very poor’, including three StRs in their 5th year of training. Less than one third (<33%) rated didactic teaching in maxillofacial prosthodontics at their unit as ‘good’ or ‘excellent’, and only 7 StRs indicated that they were confident of passing an ISFE-station focused on HANC. Conclusion Experience and training regarding patients with head and neck cancer is inconsistent for StRs across the UK and Ireland with a number of trainees reporting a lack of clinical exposure.

Objectives: To determine the prevalence of untreated carious lesions in permanent teeth in patients (under the age of 18) referred for an orthodontic assessment in specialist practice. In addition, the figures shall be compared with national data for Northern Ireland (as outlined in the recent Child Dental Health Survey 2013)
The Gold standard would be that 100% of patients would be caries free upon presentation.

Methods: The clinical records and radiographs (OPT of quality grading 1 or 2) of 337 patients were reviewed. This encompassed patients who had an orthodontic assessment carried out in specialist practice over a 6 month period (following referral from their general dental practitioner)

Results: A total of 337 patient records were examined. Of these, 149 were male (44.2%) and 188 were female (55.8%), with an age range of 7-17 years at the time of new patient assessment. It was found that 36 patients (10.7%) had evidence (clinical and/or radiographic) of active and untreated dental caries. Of those affected, 14 were male and 22 were female.
Breaking the data down in terms of age, we can also get some indication as to how this cohort compares with national data for Northern Ireland :⃰

7-10 years (Mean = 9.3) = 14.3% caries (versus NI average of 6% for 8 year olds)
11-13 years (Mean = 12.1) = 10.1% caries, (versus NI average of 16% for 12 year olds)
14-17 years (Mean = 15.2) = 9.1% caries (versus NI average of 15% for 15 year olds)

⃰using the diagnostic threshold “Decay into dentine (visual dentine caries excluded)”


Conclusion: In this sample group, a total of 10.7% of patients (9.4% of males, 11.7% of females) presented with evidence of undiagnosed caries upon being assessed as a new patient in specialist orthodontic practice. Hence, the gold standard was not met.

Background

Specialty Registrars in Restorative Dentistry (StRs) should be competent in the independent restorative management of patients with developmental disorders including hypodontia and cleft lip/palate upon completion of their specialist training.1 Knowledge and management may be assessed via the Intercollegiate Specialty Fellowship Examination (ISFE) in Restorative Dentistry.2

Objective

The aim of this study was to collate and compare data on the training and experience of StRs in the management of patients with developmental disorders across different training units within the British Isles.

Methods

Questionnaires were distributed to all StRs attending the Annual General Meeting of the Specialty Registrars in Restorative Dentistry Group, Belfast, in October 2015. Participants were asked to rate their confidence and experience of assessing and planning treatment for patients with developmental disorders, construction of appropriate prostheses, and provision of dental implants. Respondents were also asked to record clinical supervision and didactic teaching at their unit, and to rate their confidence of passing a future ISFE station assessing knowledge of developmental disorders.

Results

Responses were obtained from 32 StRs (n=32) training within all five countries of the British Isles. The majority of respondents were based in England (72%) with three in Wales, and two in each of Scotland, Northern Ireland, and the Republic of Ireland. Approximately one third of respondents (34%) were in the final years of training (years 4-6). Almost half of the StRs reported that they were not confident of independently assessing (44%) new patients with a developmental disorder, with larger numbers (72%) indicating a lack of confidence in treatment planning. Six respondents rated their experience of treating obturator patients as ‘poor’ or ‘very poor’. The majority (56%) rated their experience of implant provision in these cases as ‘good’ or ‘excellent’ with three-quarters (75%) rating clinical supervision at their unit as ‘good’ or ‘excellent’. Less than half (41%) rated the didactic teaching at their unit as ‘good’ or ‘excellent’, and only 8 StRs indicated that they were confident of passing an ISFE station focused on developmental disorders.

Conclusion

Experience and training regarding patients with developmental disorders is inconsistent for StRs across the British Isles with a number of trainees reporting a lack of clinical exposure.

Objectives Stress control (SC), a brief psycho-education course, was implemented to increase access to psychological therapies in line with Northern Irish mental health service statutory drivers. The first aim of this study was to gauge the efficacy of SC in a robust manner with clinical significance testing. The second aim was to assess whether demographics traditionally ‘hard-to-reach’ – males, younger adults and those from deprived areas – accessed SC. The third aim was to elucidate what prompted their access and the experiences of attendees at SC. Methods Attendees at SC were 170 adults over six iterations of the course. Pre- and post-questionnaires included the Depression Anxiety Stress Scales – 21, captured demographic details and qualitative feedback, which was subject to a mixed-methods analysis. Results SC attendees reported significant decreases on depression, anxiety and stress sub-scales post-intervention. Moreover, 38.71% ( n =36) of attendees who completed SC exhibited clinically significant improvement afterwards on one or more sub-scale. Attendance figures for males, younger adults and those classified as socioeconomically deprived were modest. Patterns within the data suggested prospective success for targeting these cohorts. Conclusions SC attracted people in need of mental healthcare input and affected quantifiable change within those people’s lives, while satisfying statutory demands for service delivery in an accessible community context. Recommendations to increase engagement with those traditionally ‘hard-to-reach’ for psychological services are provided, which, if implemented, have the potential to achieve further compliance with Northern Irish mental health statutory drivers.

Background: Staff who provide end-of-life care to children not only have to deal with their own sense of loss, but also that of bereaved families. There is a dearth of knowledge on how they cope with these challenges.
Aim: The aim of this review is to explore the experiences of health care professionals who provide end-of-life care to children in order to inform the development of interventions to support them, thereby improving the quality of paediatric care for both children and their families.
Data sources: Searches included CINAHL, MEDLINE, Web of Science, EMBASE, PsychINFO, and The Cochrane Library in June 2015, with no date restrictions. Additional literature was uncovered from searching reference lists of relevant studies, along with contacting experts in the field of paediatric palliative care.
Design: This was a systematic mixed studies review. Study selection, appraisal and data extraction were conducted by two independent researchers. Integrative thematic analysis was used to synthesise the data.
Results: The 16 qualitative, six quantitative, and eight mixed-method studies identified included healthcare professionals in a range of settings. Key themes identified rewards and challenges of providing end-of-life care to children, the impact on staff’s personal and professional lives, coping strategies, and key approaches to help support staff in their role.
Conclusions: Education focusing on the unique challenges of providing end-of-life care to children and the importance of self-care, along with timely multidisciplinary debriefing are key strategies for improving healthcare staffs’ experiences, and as such the quality of care they provide.
