Context and background
Historically nurses perceive politics and nursing as being at odds with the caring image, synonymous with nurses (Salvage, 1985). Furthermore the concept of the ‘politics of nursing’ lacks clear conceptual clarity (Hewison, 1994). This concept ranges across a continuum from political interest to participation or engagement (Rains et al, 2001). It is often argued political interest tends to be equated with knowledge/ involvement in health policy development and nurse education can foster political consciousness, through political socialization (Brown, 1996). But despite the World Health Organization (WHO, 2002) urging this involvement, nurses globally are largely absent from the political and policy making arena. What influences nurse’s political socialization and the development of a political consciousness is not clearly identified or known, although many commentators suggest the undergraduate educational environment, plays an important role (Hanley, 1987, Winter, 1991).
AIM
The aim of this study was to explore third year nursing student’s perceptions of politics in nursing, in the context of Northern Ireland. A number of hypotheses were tested examining the relationship between age, prior educational attainment and political interest and attitudes.
Research methodology
A cross sectional research design was used and the data was collected using a short anonymous self-completion web survey (Bryman, 2012). The sample was a convenience sample of one cohort of final year adult nursing students (n154) in one Northern Irish university, with a 42% response rate. Data was analyzed using SPSS.
Key findings and conclusions
The results revealed 55% of students were very/fairly interested in politics, with 6% reporting no interest in politics. 85% of students were registered to vote, but only 48% voted in the 2010 N Ireland Assembly election.
Recommend inclusion of a unit of study incorporating innovative teaching methods related to politics and health related policy, in the undergraduate nursing programme.

Due to earlier diagnosis and more effective treatment, increasing numbers of people can be expected to live with and beyond cancer. Yet for many, survival might be characterised by physical and psychological morbidity, decreased functional status and disability, which may increase as the length of time from the completion of treatment extends. However, careful integrated assessment and relevant and acceptable care planning can mitigate these effects; people can be helped and supported in self-management and ultimately enabled to live full and productive lives in a manner that is acceptable to them.

Background:
Men and clinicians need reliable population based information when making decisions about investigation and treatment of prostate cancer. In the absence of clearly preferred treatments, differences in outcomes become more important.
Aim:
To investigate rates of adverse physical effects among prostate cancer survivors 2-15 years post diagnosis by treatment, and estimate population burden.
Methods:
A cross sectional, postal survey to 6,559 survivors (all ages) diagnosed with primary, invasive prostate cancer (ICD10-C61), identified in Northern Ireland and the Republic of Ireland via cancer registries. Questions included symptoms at diagnosis, treatments received and adverse physical effects (impotence, urinary incontinence, bowel problems, breast changes, libido loss, hot flashes, fatigue) experienced ‘ever’ and ‘current’ i.e. at questionnaire completion. Physical effect levels were weighted by age, country and time since diagnosis for all prostate cancer survivors. Bonferroni corrections were applied to account for multiple comparisons.
Results:
Adjusted response rate 54%, (n=3,348). 75% reported at least one current physical effect (90% ever), with 29% reporting at least three. These varied by treatment. Current impotence was reported by 76% post-prostatectomy, 64% post-external beam radiotherapy with hormone therapy, with average for all survivors of 57%. Urinary incontinence (overall current level: 16%) was highest post-prostatectomy (current 28%, ever 70%). 42% of brachytherapy patients reported no current adverse physical effects; however 43% reported current impotence and 8% current incontinence. Current hot flashes (41%), breast changes (18%) and fatigue (28%) were reported more commonly by patients on hormone therapy.
Conclusions:
This study provides evidence that adverse physical effects following prostate cancer represent a significant public health burden; an estimated 1.6% of men over 45 is a prostate cancer survivor with a current adverse physical effect. This information should facilitate investigation and treatment decision-making and follow-up care of patients.

This study describes the preclinical development of a matrix-type silicone elastomer vaginal ring device designed to provide controlled release of UC781, a non-nucleoside re- verse transcriptase inhibitor. Testing of both human- and macaque-sized rings in a sink condition in vitro release model demonstrated continuous UC781 release in quantities consid- ered sufficient to maintain vaginal fluid concentrations at levels 82–860-fold higher than the in vitro IC50 (2.0 to 10.4 nM) and therefore potentially protect against mucosal trans- mission of HIV. The 100-mg UC781 rings were well tolerated in pig-tailed macaques, did not induce local inflammation as determined by cytokine analysis and maintained median con- centrations in vaginal fluids of UC781 in the range of 0.27 to 5.18 mM during the course of the 28-day study. Analysis of residual UC781 content in rings after completion of both the in vitro release and macaque pharmacokinetic studies revealed that 57 and 5 mg of UC781 was released, respectively. The pharmacokinetic analysis of a 100-mg UC781 vaginal ring in pig-tailed macaques showed poor in vivo–in vitro correlation, attributed to the very poor solubility of UC781 in vaginal fluid and resulting in a dissolution-controlled drug release mecha- nism rather than the expected diffusion-controlled mechanism.

We use unique survey data linked to nearly a decade of administrative income support data to examine the relationship between early marijuana use (at age 14 or younger) and young people's educational outcomes. We find evidence that early marijuana use is related to educational penalties that are compounded by high-intensity use and are larger for young people living in families with a history of income support receipt. The relationships between marijuana use and both high school completion and achieving a university entrance score appear to stem from selectivity into the use of marijuana. In contrast, early marijuana use is associated with significantly lower university entrance scores for those who obtain one, and we provide evidence that this effect is unlikely to be driven by selection. Collectively, these findings point to a more nuanced view of the relationship between adolescent marijuana use and educational outcomes than is suggested by the existing literature.

OBJECTIVE: To document prostate cancer patient reported 'ever experienced' and 'current' prevalence of disease specific physical symptoms stratified by primary treatment received.
PATIENTS: 3,348 prostate cancer survivors 2-15 years post diagnosis.
METHODS: Cross-sectional, postal survey of 6,559 survivors diagnosed 2-15 years ago with primary, invasive PCa (ICD10-C61) identified via national, population based cancer registries in Northern Ireland and Republic of Ireland. Questions included symptoms at diagnosis, primary treatments and physical symptoms (impotence/urinary incontinence/bowel problems/breast changes/loss of libido/hot flashes/fatigue) experienced 'ever' and at questionnaire completion ("current"). Symptom proportions were weighted by age, country and time since diagnosis. Bonferroni corrections were applied for multiple comparisons.
RESULTS: Adjusted response rate 54%; 75% reported at least one 'current' physical symptom ('ever':90%), with 29% reporting at least three. Prevalence varied by treatment; overall 57% reported current impotence; this was highest following radical prostatectomy (RP)76% followed by external beam radiotherapy with concurrent hormone therapy (HT); 64%. Urinary incontinence (overall 'current' 16%) was highest following RP ('current'28%, 'ever'70%). While 42% of brachytherapy patients reported no 'current' symptoms; 43% reported 'current' impotence and 8% 'current' incontinence. 'Current' hot flashes (41%), breast changes (18%) and fatigue (28%) were reported more often by patients on HT.
CONCLUSION: Symptoms following prostate cancer are common, often multiple, persist long-term and vary by treatment. They represent a significant health burden. An estimated 1.6% of men over 45 is a prostate cancer survivor currently experiencing an adverse physical symptom. Recognition and treatment of physical symptoms should be prioritised in patient follow-up. This information should facilitate men and clinicians when deciding about treatment as differences in survival between radical treatments is minimal.

OBJECTIVE: To compare the cost-effectiveness of conventional treatment using partial dentures with functionally orientated treatment to replace missing teeth for partially dentate elders using a randomised controlled clinical trial.
BACKGROUND: In many countries, including the Republic of Ireland, the only publically funded treatment option offered to partially dentate older patients is a removable partial denture. However, evidence suggests that these removable prostheses are unpopular with patients and can potentially increase the risk of further dental disease and subsequent tooth loss.
MATERIALS AND METHODS: Fourty-four partially dentate patients aged 65 years and older were recruited. Patients were randomly assigned to the two treatment arms of the study. The conventional treatment group received removable partial dentures to replace all missing natural teeth. The functionally orientated group was restored to a Shortened Dental Arch (SDA) of 10 occluding contacts using resin-bonded bridgework (RBB). The costs associated with each treatment were recorded. Effectiveness was measured in terms of the impact on oral health-related quality of life (OHRQoL) using OHIP-14.
RESULTS: Both groups reported improvements in OHRQoL 1 month after completion of treatment. The conventional treatment group required 8.3 clinic visits as compared to 4.4 visits for the functionally orientated group. The mean total treatment time was 183 min 19 s for the conventional group vs. 124 min 8 s for the functionally orientated group. The average cost of treatment for the conventional group was 487.74 Euros compared to 356.20 Euros for the functional group.
CONCLUSIONS: Functionally orientated treatment was more cost-effective than conventional treatment in terms of treatment effect and opportunity costs to the patients' time.

INTRODUCTION: Vocational training (VT) is a mandatory 12 month period for UK dental graduates after graduation. Graduates of Irish Dental Schools are eligible to enter the general dental service in Ireland or obtain an NHS performers list number in the UK immediately after qualification. Reports would suggest that some graduates of Irish Dental Schools are choosing to take part in VT in the UK and find the experience beneficial. This study aimed to record the uptake of VT amongst recent graduates from University College Cork and to document their experiences. It was designed to compare the attitudes and experiences of graduates of Irish Dental Schools who undertook VT compared with those who entered the general dental service.
METHOD: A self-completion questionnaire was distributed by e-mail to dental graduates from University College Cork who had graduated 2001-2007. Responses were returned by e-mail or post.
RESULTS: The response rate was 68.9%. There has been an increase in the numbers of graduates taking part in VT each year since 2004. 92.5% of Vocational Dental Practitioners (VDPs) found their experience beneficial as they received a guaranteed source of income, had a supportive peer network and worked in a positive learning environment. However, some felt that they earned a lower income than their associate colleagues, others found the pace of practice slow and that the duration of the training period was excessive. Eighty-five per cent of VDPs would choose the same position again after graduation as compared with 61.8% of associates (P < 0.001). Ninety per cent of VDPs would advise current undergraduates to take part in VT as compared with 51% of associates (P < 0.001). A larger proportion of VDPs had taken part in postgraduate studies but there was no significant difference between the two groups.
CONCLUSIONS: Larger proportions of recent graduates are undertaking vocational training.--The majority of VDPs and associates find their initial employment position beneficial.--VDPs benefit from a guaranteed source of income, a supportive peer network and a positive learning environment.--Some associates suffered from a lack of support, feeling isolated and overwhelmed with patients.--The majority of previous VDPs and associates would recommend VT to current undergraduates.--Almost 40% of associates would now choose to take part in VT if given the opportunity.

INTRODUCTION: Irish dental graduates are eligible to enter general dental practice immediately after qualification. Unlike their United Kingdom counterparts, there is no requirement to undertake vocational training (VT) or any pre-registration training. VT is a mandatory 12-month period for all UK dental graduates who wish to work within the National Health Service. It provides structured, supervised experience in training practices and through organised study days.
AIMS: This study aimed to profile the career choices made by recent dental graduates from UCC. It aimed to record the uptake of VT and associate posts, and where the graduates gained employment.
METHODOLOGY: A self-completion questionnaire was developed and circulated electronically to recent graduates from UCC. An existing database of email addresses was used and responses were returned by post or by email. A copy of the questionnaire used is included as Appendix 1.
RESULTS: Questionnaires were distributed over an eight-week period and 142 were returned, giving a response rate of 68.90%. Responses were gathered from those who graduated between 2001 and 2007; however, the majority came from more recent classes. Overall, the majority of graduates took up associate positions after qualification (71.8%) with smaller numbers undertaking VT (28.2%). Increasing numbers have entered VT in recent years, including 54.3% from the class of 2007. Overall, the majority of graduates initially took up positions in England (43%); however, in recent times more have been employed in Scotland. Subsequent work profiles of the graduates illustrate that the majority are now working as associates in general practice (51.4%) and in Ireland (54.2%).
CONCLUSIONS: There has been an increase in the proportion of UCC graduates undertaking VT. Graduates tended to move away from Ireland initially to gain employment. There has been a shift away from employment in England towards Scotland where the majority of new UCC graduates are now initially employed. The majority of graduates returned to Ireland for employment after the initial move away.

Background: This survey aimed to record the dietary habits and oral health behaviours of patients undergoing methadone maintenance therapy at a Scottish drug rehabilitation centre.The objectives were to obtain descriptive data for each of the participants on items including dietary habits, oral hygiene practices and dental health. The study also aimed to explore explanatory relationships between dietary habits, oral hygiene practices and dental health (DMFT) in methadone users.
Methods: A cross – sectional descriptive study using survey methodology was conducted of consecutive adult patients undergoing methadone maintenance therapy at a non-residential drug rehabilitation centre in Dundee, Scotland. A self-completion retrospective questionnaire was distributed to 66 consecutive patients.
Results: A response rate of 74.2% was achieved. Participants reported low daily intakes of fresh fruit and vegetables with diets high in fatty foods. Respondents reported regular snacking between meals and consumption of large amounts of sugared carbonated drinks. Oral hygiene practices were poorly adhered to and a high level of dental disease was observed amongst participants. Poisson regression analysis revealed that the amount of alcohol consumed per day (p=0.02), the length of time taking methadone (p=0.002) the amount of sugar added to hot drinks (p<0.0001) and regular dental attendance (p=0.0001) were all independently associated with poor dental health.
Conclusions: Dietary habits and adherence to oral hygiene practices amongst this group of patients were very poor. This study suggests that these behaviours were contributing to the high levels of dental disease observed in this group.

Nematode neuropeptide systems comprise an exceptionally complex array of similar to 250 peptidic signaling molecules that operate within a structurally simple nervous system of similar to 300 neurons. A relatively complete picture of the neuropeptide complement is available for Caenorhabditis elegans, with 30 flp, 38 ins and 43 nlp genes having been documented; accumulating evidence indicates similar complexity in parasitic nematodes from clades I, III, IV and V. In contrast, the picture for parasitic platyhelminths is less clear, with the limited peptide sequence data available providing concrete evidence for only FMRFamide-like peptide (FLP) and neuropeptide F (NPF) signaling systems, each of which only comprises one or two peptides. With the completion of the Schmidtea meditteranea and Schistosoma mansoni genome projects and expressed sequence tag datasets for other flatworm parasites becoming available, the time is ripe for a detailed reanalysis of neuropeptide signaling in flatworms. Although the actual neuropeptides provide limited obvious value as targets for chemotherapeutic-based control strategies, they do highlight the signaling systems present in these helminths and provide tools for the discovery of more amenable targets such as neuropeptide receptors or neuropeptide processing enzymes. Also, they offer opportunities to evaluate the potential of their associated signaling pathways as targets through RNA interference (RNAi)-based, target validation strategies. Currently, within both helminth phyla, the flp signaling systems appear to merit further investigation as they are intrinsically linked with motor function, a proven target for successful anti-parasitics; it is clear that some nematode NLPs also play a role in motor function and could have similar appeal. At this time, it is unclear if flatworm NPF and nematode INS peptides operate in pathways that have utility for parasite control. Clearly, RNAi-based validation could be a starting point for scoring potential target pathways within neuropeptide signaling for parasiticide discovery programs. Also, recent successes in the application of in planta-based RNAi control strategies for plant parasitic nematodes reveal a strategy whereby neuropeptide encoding genes could become targets for parasite control. The possibility of developing these approaches for the control of animal and human parasites is intriguing, but will require significant advances in the delivery of RNAi-triggers.

Hip replacement surgery is amongst the most common orthopaedic operations performed in the UK. Aseptic loosening is responsible for 40% of hip revision procedures. Aseptic loosening is a result of cement mantle fatigue. The aim of the current study is to analyse the effect of nanoscale Graphene Oxide (GO) on the mechanical properties of orthopaedic bone cement. Study Design A experimental thermal and mechanical analysis was conducted in a laboratory set up conforming to international standards for bone cement testing according to ISO 5583. Testing was performed on control cement samples of Colacryl bone cement, and additional samples reinforced with variable wt% of Graphene Oxide containing composites – 0.1%, 0.25%, 0.5% and 1.0% GO loading. Pilot Data Porosity demonstrated a linear relationship with increasing wt% loading compared to control (p<0.001). Thermal characterisation demonstrated maximal temperature during polymerization, and generated exotherm were inversely proportional to w%t loading (p<0.05) Fatigue strength performed on the control and 0.1 and 0.25%wt loadings of GO demonstrate increased average cycles to failure compared to control specimens. A right shift of the Weibull curve was demonstrated for both wt% available currently. Logistic regression analysis for failure demonstrated significant increases in number of cycles to failure for both specimens compared to a control (p<0.001). Forward Plan Early results convey positive benefits at low wt% loadings of GO containing bone cement. Study completion and further analysis is required in order to elude to the optimum w%t of GO which conveys the greatest mechanical advantage.

Background This study evaluated the effect of statins in Primary biliary cirrhosis (PBC) on endothelial function, anti-oxidant status and vascular compliance. Methods Primary biliary cirrhosis patients with hypercholesterolaemia were randomized to receive 20mg simvastatin or placebo in a single blind, randomized controlled trial. Body mass index, blood pressure, glucose, liver function, lipid profile, immunoglobulin levels, serological markers of endothelial function and anti-oxidant status were measured as well as vascular compliance, calculated from pulse wave analysis and velocity, at recruitment and again at 3, 6, 9 and 12months. Results Twenty-one PBC patients (F=20, mean age = 55) were randomized to simvastatin 20mg (n=11) or matched placebo (n=10). At completion of the trial, serum cholesterol levels in the simvastatin group were significantly lower compared with the placebo group (4.91mmol/L vs. 6.15mmol/L, P=0.01). Low-density lipoprotein (LDL) levels after 12months were also significantly lower in the simvastatin group (2.33mmol/L vs. 3.53mmol/L, P=0.01). After 12months of treatment, lipid hydroperoxides were lower (0.49mol/L vs. 0.59mol/L, P=0.10) while vitamin C levels were higher (80.54mol/L vs. 77.40mol/L, P=0.95) in the simvastatin group. Pulse wave velocity remained similar between treatment groups at 12months (8.45m/s vs. 8.80m/s, P=0.66). Only one patient discontinued medication owing to side effects. No deterioration in liver transaminases was noted in the simvastatin group. Conclusions Statin therapy in patients with PBC appears safe and effective towards overall reductions in total cholesterol and LDL levels. Our initial study suggests that simvastatin may also confer advantageous effects on endothelial function and antioxidant status.

Objectives: This study aimed to gather data on the nutritional status of older patients attending Cork University Dental School and Hospital for treatment in the Restorative Department. Information was also collected about the medical status of the patients including the prevalence of self-reported xerostomia.
Methods: Data was collected by a self-completion questionnaire followed by a brief clinical examination. Nutritional Status was measured using the short version of the Mini Nutritional Assessment (MNA) which recorded patients’ Body Mass Index (BMI). The MNA consists of 6 parameters (including questions relating to patients’ history and anthropometric data) with a maximum total of 14 points. Scores of 12-14 indicate “normal nutritional status” whilst those between 8 and 11 indicate a patient “at risk of malnutrition”. Scores lower than 8 are an indication a patient who is “malnourished”. All patients attending Cork University Dental School and Hospital aged 65 years and older were invited to participate in the study.
Results: A total of 22 subjects participated in this study. Twelve patients were partially dentate with 10 edentulous. The results from the MNA indicate that 11 patients were of “normal nutritional status” with 11 patients identified as being “at risk of malnutrition”. None of the subjects were “malnourished”. Edentate patients generally recorded lower MNA scores than partially dentate patients. In total, 9 patients reported experiencing xerostomia with 8 indicating that they needed to sip liquids to aid swallowing but only 3 had difficulty swallowing food.
Conclusion: This small study indicates that a number of the older patients attending Cork University Dental School and Hospital for dental care may be “at risk of malnutrition”. These findings suggest that nutritional advice and dental care should both be included in an overall package of care for older patients.

Objectives: This study aimed to compare the cost effectiveness of conventional treatment using partial dentures with functionally-orientated treatment based on the shortened dental arch concept to replace missing teeth for partially dentate elders.
Methods: 44 partially dentate patients aged 65 years and older were recruited following routine dental assessment at a university dental hospital. Patients consented to and were randomly assigned to the two treatment arms. The conventional treatment group received a removable partial denture to replace all missing natural teeth. The functionally-orientated group were restored to a shortened dental arch of 10 occluding contacts using resin bonded bridgework. The costs associated with each treatment were recorded including laboratory charges, treatment time and opportunity costs. The impact on quality of life (OHRQoL) was measured using the 14-item Oral Health Impact Profile.
Results: Both groups reported improvements in OHRQoL after completion of treatment. For the conventional group, the mean OHIP-14 score decreased from 12.4 pre-operatively to 3.3 post-operatively (p<0.001). In the functionally-orientated group the OHIP-14 score decreased from 11.4 to 1.8 following treatment (p<0.001). On average the conventional treatment group required 8.3 clinic visits as compared to 4.4 visits for the functionally-orientated group. The mean total treatment time was 183 minutes 19 seconds for the conventional group versus 124 minutes 8 seconds for the functionally-orientated group. The conventional treatment group had an average of 6.33 teeth replaced at a laboratory cost of 337.31 Euros. The functionally-orientated group had an average of 2.64 teeth replaced at a laboratory cost of 244.05 Euros.
Conclusions: Restoration to a shortened dental arch using functionally-orientated treatment resulted in a similar improvement in OHRQoL with fewer clinic visits, less operative time and at a lower laboratory cost compared with conventional treatment.
