Abstract
PURPOSE/OBJECTIVE(S) Men with low serum prostate-specific antigen (PSA) and high Gleason grade group (GGG) are thought to have poor outcomes compared to high PSA secretors. However, there is limited outcome data to support this. We report clinical outcomes from a single-institutional cohort of men presenting with locally advanced prostate cancer but low serum PSA. MATERIALS/METHODS Data from electronic database of a UK tertiary cancer center was acquired for men with histological diagnosis of prostate adenocarcinoma, GGG 4 or 5, stage ≥cT3a, and PSA <10ug/L at diagnosis. Men with metastatic disease, or prior androgen deprivation therapy (ADT) were excluded. Biochemical progression was defined as per Phoenix criteria (PSA > nadir+2) for primary radiotherapy, or PSA >0.2 ug/L after primary prostatectomy (and post-operative radiotherapy, if received). Overall survival (OS, from date of diagnosis to death), metastasis-free survival (MFS, from diagnosis to first recorded metastasis or death), and biochemical progression free survival (bPFS, from diagnosis to biochemical progression or death) were estimated by Kaplan Meier method, and multivariable analysis performed using Cox proportional hazards method. RESULTS Medical records of 7,200 men presenting with non-metastatic prostate cancer from 2013 to 2021 were screened, of which 270 men satisfying the eligibility criteria were included for this study. Initial analysis of 123 men shows median PSA at presentation 7.1 ug/L (IQR 5.6-8.5), and median age 70 years (IQR 65-75). Histology was GGG 4 in 47.6% and 5 in 52.4%. Tumor stage was cT3a in 56.6%, cT3b in 36.9%, and T4 in 6.6%. Pelvic nodes were involved in 5% patients. Majority (83.7%) were treated with radical radiotherapy (external beam alone 64.2%, brachytherapy boost 19.5%), with 24 months ADT; 11.4% underwent radical prostatectomy, and 4.9% received ADT alone. Three men (2.4%) received docetaxel, and one received abiraterone. At a median follow up of 66 months (IQR 27-77), 36 (29.3%) patients had biochemical failure. Total 23 (18.6%) patients had metastases at recurrence, which were visceral in 4%, bone-only in 10%, and nodal-only in 4%. Total 38 (30.6%) patients had died, 23% with prostate cancer and 11% due to other causes. Five-year bPFS was 65.9%, MFS 69.0%, and OS was 77.4%. GGG 5 (versus 4) was associated with significantly worse 5-year bPFS (59.4% vs 73.9%, HR 1.8, 95% CI 1.0-3.2, p = 0.05) and MFS (59.2% vs 81.6%, HR 2.2, 1.2-4.2, p = 0.02). On multivariable analysis including age and PSA at diagnosis, only GGG 5 was associated with worse bPFS (HR 1.8, 1.0-3.3, p = 0.05) and MFS (HR 2.42, 1.25-4.67, p = 0.009). CONCLUSION Men with low secreting but high Gleason grade group prostate cancer are a relatively rare group with poor clinical outcomes despite being non-metastatic. Ongoing work (expected completion June 2023) will analyze remaining cases, and compare outcomes within an expanded multicentric cohort with matched controls having elevated PSA at presentation.

Abstract
INTRODUCTION Post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) is an important tool in the management of advanced germ cell testis cancer, particularly non-seminoma. AIM We present the 16-year experience with PC-RPLND in a single Irish tertiary referral centre, and compare our results to the major speciality centres worldwide. METHODOLOGY All 78 patients undergoing PC-RPLND for the treatment of metastatic testis cancer between January 1996 and December 2011 were included. Medical records were reviewed and up to date follow-up obtained from primary referral centres, patient's GPs and individual patient interview. RESULTS The mean age at diagnosis was 28.5 ± 7 years. Initial pathology included non-seminoma 62.8 %, seminoma 6.4 % and combined 19.2 %. All patients underwent pre-operative chemotherapy. The resection template utilised was bilateral infra-hilar in 29.5 %, unilateral infra-hilar in 46.2 % and supra-hilar in 20.5 %. Complete abdominal remission was achieved in all but one patient. Additional procedures were required in 38.5 % of patients (n = 30). Clavien Dindo grade three or four complications were seen in 8.9 %, including five patients who required early reoperation. Histology of RPLND specimen showed mature teratoma (41 %) and active cancer (11.5 %). Follow-up data were available for 66 patients (85 %). Median follow-up was 101 (11-207) months. Nine patients relapsed with median time to relapse 15 (8-60) months. Overall 5-year survival rate was 95.2 % (four deaths). CONCLUSION In this relatively small series due to small population and low disease incidence, we have shown acceptable peri-operative course, morbidity and oncological outcomes with PC-RPLND compared to major international centres.

Abstract
Large national reviews of patient charts estimate that approximately 10% of hospital admissions are associated with an adverse event (defined as an injury resulting in prolonged hospitalization, disability or death, caused by healthcare management). Apart from having a significant impact on patient morbidity and mortality, adverse events also result in increased healthcare costs due to longer hospital stays. Furthermore, a substantial proportion of adverse events are preventable. Through identifying the nature and rate of adverse events, initiatives to improve care can be developed. A variety of methods exist to gather adverse event data both retrospectively and prospectively but these do not necessarily capture the same events and there is variability in the definition of an adverse event. For example, hospital incident reporting collects only a very small fraction of the adverse events found in retrospective chart reviews. Until there are systematic methods to identify adverse events, progress in patient safety cannot be reliably measured. This review aims to discuss the need for a safety culture that can learn from adverse events, describe ways to measure adverse events, and comment on why current adverse event monitoring is unable to demonstrate trends in patient safety.

Abstract
BACKGROUND Management of death and dying is an important aspect of nursing practice. Many nursing students have not been exposed to death prior to their commencement in nurse education and typically do not encounter dying and death until their clinical experience begins. OBJECTIVES To examine the effects and impact of exposure of nursing students to an anatomy room for anatomy teaching compared with students taught anatomy in a laboratory using plastic anatomical specimens. METHODS Two groups of first year nursing students were surveyed; one group received tuition in anatomy using plastic specimens and the second group used dissected cadavers. Questionnaires were administered before and immediately after the first teaching experience and again 9 weeks later. RESULTS Students studying anatomy using cadaveric specimens were more apprehensive of subsequent visits to the anatomy room. However, after 9 weeks there was no significant difference when compared to students using plastic specimens. The students using cadavers felt significantly more stressed and reported significantly more symptoms than those using plastic specimens after their first lesson. There was no significant difference in stress levels and symptom reporting between the groups after 9 weeks. While a large proportion of the students using both cadavers (97%) and plastic specimens (88%) found their learning experiences positive, 43% of the respondents using cadavers stated that as a result of this experience they felt more prepared to deal with death in a hospital and that they were happy to see death in a stress free environment. The responses from the group using plastic specimens were positive as essentially they had found the theory easier to learn. CONCLUSIONS The results suggest that learning anatomy using cadavers is a beneficial learning experience and could be a valuable way to encounter death for the first time in a protected environment rather than in the clinical setting.

Abstract
Sex trafficking within Ireland is a hidden phenomenon. In 2010, 78 alleged victims were reported to An Garda Siochina and the recorded levels of human trafficking into Ireland have remained at this level for the last four years. Despite this, no Irish guidelines or referral pathways exist to assist health care professionals. This paper highlights that health care professionals are not aware of this occurrence nor have they been trained to identify victims. Due to a lack of awareness many potential opportunities to detect these victims may be missed. While there is no single set of symptoms or signs that differentiates sex-trafficked victims from other sex workers, an awareness of common physical and psychological health problems associated with sex trafficking by health care professionals may increase victim detection rates. This paper summarises indicators, approach mechanisms, screening questions and a referral guideline relevant to the Irish health care system. This step-by-step guide can be used by health care professionals who encounter such a situation.

Abstract
Background. Depression is an increasing problem in older adults, which is exacerbated by under diagnosis and ineffective treatment options. Broadly speaking, as people age, their levels of regular physical activity (PA) decrease, while their experience of chronic pain increases. PA has been shown to be an effective, yet under-utilised, treatment for depression in this age-cohort although the influence of pain on the relationship between PA and depressive symptoms has not been considered. Methods. Secondary analysis of national data from The Irish Longitudinal Study on Ageing (TILDA, 2011) (n = 8163 participants aged 50 years and older) examined the mediating or moderating role of pain in the relationship between depressive symptoms and PA, and the impact of PA, pain and depressive symptoms on health-care utilisation. Results. Approximately 8.5% TILDA older adults were depressed. No mediating or moderating effects of pain were found in the association between PA and depressive symptoms. Higher levels of PA were found to be independently associated with lower depressive symptoms, while higher levels of pain significantly increased the likelihood of depressive symptoms supporting previous findings. Depressive symptoms and higher levels of pain were also found to significantly increase health-care utilisation. Conclusions. Consistent with previous findings in this field, both PA and pain were found to be independently associated with depressive symptoms in Irish older adults. Furthermore, pain does not play a mediating or moderating role in the relationship between PA and depressive symptoms. Continued support for ongoing initiatives in this area aimed at increasing PA in older adults as a means to improve both physical and mental well-being is advised. The absence of any synergistic effect between PA and pain suggests that clinicians and health service providers should continue to promote PA as a treatment for depression, irrespective of the pain levels of their patients.

Abstract
AIM Advanced glycation end products (AGEs) and/or their receptors (RAGE) are significantly positively correlated with adiposity, inflammation, dyslipidemia, and insulin resistance in adults. However, the relationships between AGEs, RAGE, and adiposity-related comorbidites in children have not been well studied. METHODS In a cross-sectional study of 88 children (age 11-15 years) from the New York area enrolled in the Reduce Obesity and Diabetes (ROAD) study, we examined the correlation of the AGE N(ε)-(carboxymethyl)lysine (CML), soluble RAGE (sRAGE), and endogenous secretory RAGE (esRAGE) with adiposity, inflammatory markers [interleukin-6 (IL-6), C-reactive protein, tumor necrosis factor-α], adiponectin, lipids, insulin sensitivity, and insulin secretory capacity. RESULTS Pediatric CML levels were ~20% below average adult levels. CML was significantly (p < 0.05) positively correlated with age and insulin sensitivity and negatively with adiposity, dyslipidemia and IL-6. sRAGE correlated positively with esRAGE and negatively with adiposity and IL-6. Both sRAGE and esRAGE correlated negatively with insulin secretory capacity. CONCLUSION Our findings suggest that unlike adults, CML is negatively associated with adiposity and adiposity-related comorbidity risk in children. As in adults, sRAGE and esRAGE were, to varying degrees, negatively correlated with body fatness and risk factors for adiposity-related comorbidities.

Abstract
Background. Ireland is estimated to have the highest European incidence rate of prostate cancer (Pca) in 2006 which will increase by 275% by 2025. This study aimed to determine PSA cutoff values in different age groups of healthy male patients without Pca. Methods. 660 men in a pilot men's health programme, aged 18–67, had PSA assayed. Men were grouped into 8 age groups at 5-year intervals: 30–34, 35–39, 40–44, 45–49, 50–54, 55–59, 60–64, and 64–70. Results. Linear regression demonstrates a PSA velocity of 0.024 ng/ml/year. The 95% confidence interval demonstrates a near flat line of PSA values from age 20 to 50 and rises after. When transformed logarithmically, PSA correlates highly with expected values from the normal distribution (0.98). A fractional polynomial quantile regression model was used to predict median and 95th percentile for PSA as follows: 30–34 (0.73, 1.57), 35–39 (0.71, 1.65), 40–44 (0.73, 1.85), 45–49 (0.78, 2.17), 50–54 (0.88, 2.63), 55–59 (1.01, 3.25), 60–64 (1.20, 4.02), and 64–70 (1.43, 4.96). Conclusions. PSA levels are similar to other racial groups but not as high as US Caucasians until 65 years. These data define the predicted PSA for the Irish population and provide a reference for future screening programmes.

Abstract
Cervical cancer represents the second common cancer in women and is a major public health issue in Ireland and worldwide. Despite appropriate treatment of precancerous lesions, women with dysplasia are at relatively increased risk, and require follow up. We aimed to evaluate the compliance rate with follow up cytology advice given to patients discharged from the colposcopy clinic and to identify predictive factors for poor compliance. This is a retrospective cohort study of patients initially managed in our institution in 2001. Patients were evaluated for adherence with the recommendations received at the time of discharge from the clinic. Of the 116 women that were initially contacted, 100 agreed to participate in the study (86% response rate). Sixty women (60%) were entirely compliant. While older patients (> 40 years) were significantly less likely to show complete compliance (OR: 0.12; 950/ Cl: 0.02-0.58; p = 0.009).

Abstract
OBJECTIVE It is well-established that maternal smoking has adverse birth outcomes (low birthweight, LBW, and preterm births). The comprehensive Irish workplace smoking ban was successfully introduced in March 2004. We examined LBW and preterm birth rates 1 year before and after the workplace smoking ban in Dublin. DESIGN A cross-sectional observational study analysing routinely collected data using the Euroking K2 maternity system. SETTING Coombe University Maternal Hospital. POPULATION Only singleton live births were included for analyses (7593 and 7648, in 2003 and 2005, respectively). METHODS Detailed gestational and clinical characteristics were collected and analysed using multivariable logistic regression analyses and subgroup analyses. MAIN OUTCOME MEASURES Maternal smoking rates, mean birthweights, and adjusted odds ratios (ORs) of LBW and preterm births in 2005 versus 2003. RESULTS There was a 25% decreased risk of preterm births (OR, 0.75; 95% CI, 0.59-0.96), a 43% increased risk of LBW (OR, 1.43; 95% CI, 1.10-1.85), and a 12% fall in maternal smoking rates (from 23.4 to 20.6%) in 2005 relative to 2003. Such patterns were significantly maintained when specific subgroups were also analysed. Mean birthweights decreased in 2005, but were not significant (P=0.99). There was a marginal increase in smoking cessation before pregnancy in 2005 (P=0.047). CONCLUSIONS Significant declines in preterm births and in maternal smoking rates after the smoking ban are welcome signs. However, the increased LBW birth risks might reflect a secular trend, as observed in many industrialised nations, and merits further investigations.

Abstract
This cross-sectional study was aimed to identify the predictors of medication noncompliance in hypertensive patients. The study was conducted at the Family Medicine Clinic, Hospital Universiti Sains Malaysia, Kelantan, Malaysia, which is a university-based teaching hospital. All hypertensive patients aged 40 or over-registered from January to June 2004, who had been on treatment for at least 3 months, were screened. Previously validated self-administered questionnaires were used to assess the compliance and psychosocial factors. A total of 240 hypertensive patients were recruited in the study. Of these, 55.8% were noncompliant to medication. Logistic regression showed that age (adjusted odds ratio (OR): 0.96; 95% confidence interval (CI): 0.92-0.997; P: 0.035), patient satisfaction (adjusted OR: 0.97; 95% CI: 0.93-0.998; P: 0.036) and medication barrier (adjusted OR: 0.95; 95% CI: 0.91-0.987; P: 0.009) were significant predictors of medication noncompliance. Therefore, younger age, poor patient satisfaction and medication barrier were identified as independent psychosocial predictors of medication noncompliant in hypertensive patients.

Abstract
BACKGROUND Lung carcinoma usually is advanced at the time of presentation and frequently shows metastatic spread. In recent times, prognostic factors such as c-erbB-2 in patients with breast carcinoma have provided useful information and beneficial therapeutic targets. The objective of this study was to evaluate angiogenesis, immune function, and telomerase expression in patients with nonsmall cell lung carcinoma (NSCLC) to determine their prognostic significance. METHODS Immunohistochemistry was used to evaluate the expression of human telomerase reverse transcriptase (hTERT; n = 115 patients), interleukin-2r (IL-2r; n = 40 patients), microvessel density (MVD; n = 81 patients), and vascular endothelial growth factor (VEGF; n = 61 patients). Three-year survival follow-up information was available for most patients, and a comprehensive review of clinicopathologic features was carried out. RESULTS Fifty percent of tumors showed nuclear staining for hTERT, 55% of tumors showed some degree of lymphocyte IL-2r expression, 33% of tumors were recorded with an MVD that was higher than average, and VEGF staining was detected in 85% of tumors. None of the parameters measured had an impact on survival. hTERT expression was correlated with lymph node status. Lymph node status and tumor size were identified as independent prognostic factors. CONCLUSIONS This study failed to identify a marker of prognosis for patients with NSCLC other than tumor size and lymph node status in this population. Telomerase expression was associated with metastases, raising the possibility that this enzyme is involved in the metastatic process. Tumor cell VEGF expression was identified frequently: This growth factor may have potential as a target for antiangiogenic therapy. Lung carcinoma typically is the result of large numbers of mutations. Further understanding of the biologic implications of these mutations will lead to the development of effective prognostic markers and treatments for patients with NSCLC.

Abstract
OBJECTIVE To report plasma concentrations of the adhesion cell molecule P-selectin during pregnancy to determine the effect of subsequent development of hypertension and pre-eclampsia. DESIGN A longitudinal study. METHODS A longitudinal study involving 70 women followed up from early pregnancy; 20 who subsequently developed pre-eclampsia were compared with 24 who developed gestational hypertension and 26 normotensive women with normal obstetric outcome. The determination of citrate plasma soluble P-selectin levels throughout pregnancy was performed using a commercial quantitative sandwich immunoassay kit. The temporal course of plasma P-selectin in the three groups of subjects was analysed. RESULTS There was no significant difference in mean plasma P-selectin concentration between normotensive and gestational hypertensive subjects at any stage of pregnancy. Using a cutoff level of 60 ng/mL, P-selectin concentration at 10-14 weeks had a negative predictive value for pre-eclampsia of almost 99%. Mean plasma P-selectin concentrations were significantly elevated by 10-14 weeks in women who later developed pre-eclampsia (P < 0.001). CONCLUSIONS Our data support an inflammatory model for pre-eclampsia whereby endothelial cell activation may be secondary to a primary inflammatory response. Plasma P-selectin has significant potential as a first trimester clinical marker of pre-eclampsia.

Abstract
The aims of this study were to identify risk factors for scar dehiscence in labour, to illustrate the clinical presentations of patients with scar dehiscence and to quantify the risk posed by the use of oxytocin in labour. This was a case controlled, 5 year retrospective study. Patients with scar dehiscence were identified from labour ward records with matched controls and chart review of case and control patients were performed. Our results showed that the vaginal delivery rate for trial of scar was 76.9%. The incidence of scar dehiscence was 0.043%. Oxytocic labour augmentation was a risk factor (OR 4.5, 95% CI 0.9313-42.8, p=0.065) but induction of labour using oxytocin was not (p=0.222). The commonest symptom of scar dehiscence was fetal distress (OR 12.3, 95% CI 1.9-81). There was no maternal or fetal mortality. We concluded that trial of labour after one caesarean section is acceptable practice with a good success rate and a low incidence of serious morbidity. The use of oxytocin to augment labour is associated with scar dehiscence.

Abstract
OBJECTIVE The aim of this study was to measure maternal plasma vascular endothelial growth factor concentrations during normal and hypertensive pregnancies and examine their relationship with maternal total peripheral resistance values. STUDY DESIGN Plasma concentrations of total immunoreactive vascular endothelial growth factor and total peripheral resistances were measured serially throughout pregnancy in 20 women with preeclampsia, 24 women with gestational hypertension, and 26 normotensive control women. One-way analysis of variance and a regression model were used to analyze the vascular endothelial growth factor levels in the groups and the relationship between vascular endothelial growth factor concentration and total peripheral resistance. RESULTS At 10 to 14 weeks' gestation plasma vascular endothelial growth factor concentrations in all subjects were 4 to 5 times greater than the levels measured post partum (P <.0001). Mean vascular endothelial growth factor concentrations were similar in the control and gestational hypertension groups; in both groups levels remained stable until 34 to 36 weeks' gestation, when levels increased a further 1.3-fold (P <.01). In comparison, vascular endothelial growth factor concentrations in subjects in the preeclampsia group were greater at 28 to 32 weeks' gestation (P =.002) and at 34 to 36 weeks' gestation (P <.001). Vascular endothelial growth factor concentrations were also increased during the 4 weeks that preceded the diagnosis of preeclampsia (P <.05). Vascular endothelial growth factor concentrations were associated with the elevated total peripheral resistance observed during the clinical disorder in the preeclampsia group but not in the other groups. CONCLUSION Maternal plasma vascular endothelial growth factor concentrations increased before the clinical onset of preeclampsia and were further elevated during the vasoconstricted state observed in this disorder. We speculate that the hyperdynamic circulation that characterizes the latent phase of preeclampsia causes vascular shear stress, which in turn increases the levels of circulating vascular endothelial growth factor. Because vascular endothelial growth factor normally acts as a vasodilator, its increase may represent an unsuccessful vascular rescue response.

Abstract
OBJECTIVES This study was conducted to determine whether the amount of myocardial damage during acute coronary syndromes (ACS) is related to the admission plasma homocysteine concentration. BACKGROUND Elevated homocysteine levels are associated with increased thrombosis in patients presenting with ACS. It is not known whether this association is reflected in the degree of myocardial injury in those patients. METHODS We studied consecutive patients presenting with acute myocardial infarction (MI) (n = 205) and unstable angina pectoris (UAP) (n = 185). Plasma samples were collected on admission and prior to clinical intervention and were assayed for homocysteine by high performance liquid chromatography (HPLC). Myocardial necrosis was assessed by measurements of cardiac troponin T (cTnT) on admission and 12 h after admission (peak cTnT). The patients were studied by quintiles of homocysteine concentration. RESULTS There was a significant increase in peak cTnT in the 5th homocysteine quintile in MI (analysis of variance [ANOVA], p = 0.005), the levels being 4.10, 3.86, 4.13, 6.20 and 7.85 microg/liter for quintiles 1 to 5, respectively (p < 0.0001, for top vs. bottom quintile). Similarly, there was a step-up in peak cTnT levels in the top homocysteine quintile in UAP (ANOVA, p < 0.0001), the levels being 0.03, 0.03, 0.02, 0.04 and 0.15 microg/liter, (p < 0.0001 for top vs. bottom quintile). In a multivariate regression model, the association between peak cTnT and the top homocysteine quintile remained strong after adjustment of other confounders including age, gender, final diagnosis and thrombolysis treatment (odds ratio [OR]: 2.92 (1.75-4.87) p < 0.0001). The patients with UAP were further examined according to peak cTnT levels below (cTnT negative) or above (cTnT positive) 0.1 microg/liter. Homocysteine levels were significantly higher in cTnT positive than cTnT negative patients; 13.8 (11.7-15.3) vs. 10.3 (9.4-11.3) micromol/liter, respectively, p = 0.002. CONCLUSIONS Elevated homocysteine levels are associated with a higher risk of ischemic myocardial injury in patients presenting with ACS.

Abstract
OBJECTIVE To document maternal central hemodynamics during the preclinical and clinical phases of nonproteinuric gestational hypertension and preeclampsia. METHODS We conducted a longitudinal study of 400 primigravidas who were monitored throughout pregnancy using Doppler echocardiography. Multinomial logistic regression was used to identify variables associated with risk of hypertension. RESULTS Gestational hypertension developed in 24 women and preeclampsia developed in 20. Compared with normotensive controls, women who had preeclampsia had significantly elevated cardiac outputs before clinical diagnosis, but total peripheral resistance was not significantly different during this latent phase. During the clinical phase of preeclampsia, there was a marked reduction in cardiac output and increase in peripheral resistance. All women who had gestational hypertension had significantly elevated cardiac outputs before and during the clinical course of the condition. CONCLUSION Our data support the concept of a hyperdynamic disease model for preeclampsia, with a subsequent hemodynamic crossover to low cardiac output and high resistance circulation coinciding with the onset of the clinical syndrome. Women with gestational hypertension had no such hemodynamic crossover and maintained hyperdynamic circulation throughout pregnancy.

Abstract
OBJECTIVES To describe (1) the characteristics of attenders to an urban accident and emergency (A&E) department over a one year period according to the frequency of their attendance and (2) the features of their attendances according to the frequency which the patient attended the department during the study period. METHODS A dataset containing information on all new attendances to an urban A&E department in 1995 was formed. For each attendance the following information was recorded: day of the week, hour of attendance, referral source, triage category, and disposal. A second dataset, consisting of the individuals ("attenders") who made the A&E visits ("attendances") during 1995 was also produced. For each attender the following information was recorded: age, sex, postal code of residence, socioeconomic status, marital status, and number of attendances during 1995. A methodology reviewing the trends of frequency of attendance was utilised, as opposed to the use of an arbitrary cut off point. RESULTS 34,908 patients made 46,735 visits in 1995. Increasing frequency of attendance was significantly associated with increasing age (Kruskal-Wallis < 0.001), being male (chi 2 for linear trend 14.06, p < 0.001), having a local postal address (chi 2 279.79, p < 0.0001), general medical services eligibility (chi 2 781.67, p < 0.0001), and inversely associated with being married (chi 2 33.91, p < 0.0001). Increasing frequency of attendance was significantly associated with attendance between the hours of 1700 and 0900 (chi 2 295.62, p < 0.001), being triaged as a non-emergency (chi 2 1254.33, p < 0.0001), and self referral (chi 2 141.4, p < 0.0001). CONCLUSIONS A small group of A&E attenders accounts for a disproportionately large percentage of the total number of departmental attendances. The characteristics of frequent A&E attenders suggest that they may represent a vulnerable group of patients. A follow up study of the utilisation of all primary care services by such patients is suggested.

Abstract
This report examines initial distress levels, course of symptoms, incidence of posttraumatic stress disorder (PTSD), predictors of short-term outcome, and value of prophylactic counseling in a consecutive series of 40 ambulant trauma clinic attenders with minor road traffic accident (RTA) injuries. Subjects were randomly allocated to intervention and monitoring groups following assessment at a mean of 7 days posttrauma and reassessed at 3 months using a variety of standard rating scales. Seventy-five percent reported significant levels of distress at 1 week posttrauma. By 3 months this had decreased sharply to 35%, and 22% were significantly impaired by clinical assessment. Incidence of PTSD over 3 months was estimated at 19% and point prevalence at 3 months posttrauma was 9%. High initial distress, increasing age, and high levels of perceived threat were significant independent predictors of morbidity, and no significant differences in outcome were found between intervention and monitoring groups at 3 months.

Abstract
The primary aim of this study was to investigate obstetric outcomes in teenagers delivered in the Rotunda Hospital and to identify whether younger teenagers have a poorer obstetric outcome. Delivery record details were recorded from the years 1992-96. These included the number of teenage mothers, maternal age, parity, gestation, mode of delivery, birth weight and Apgar scores. Teenagers were classified into those aged under 17 years and those aged 17 and over. Overall 2,228 teenage mothers were delivered in the Rotunda hospital, representing 17.2% of the total teenage population delivered in Ireland during the study period. Ten percent of mothers were under 17 years; 10.6% were multiparous with 2.6% of these under 17 years. There was a significant difference in the preterm delivery rate when the teenagers were compared as a whole with matched controls aged 20-24 years (p = 0.0411). However this did not translate into a poorer neonatal outcome as on average only 5% of babies were low birth weight and only 3% had Apgar scores < 3. Overall 70.2% of deliveries were spontaneous, 20.2% were instrumental. Less than 10% of deliveries were by caesarean section. However the rate of caesarean section increased with age from 14 (5.7%) to 19 (13.5%) years and this trend was statistically significant (p = 0.013). In conclusion, this study does not support the view that younger teenage mothers have a poorer obstetric and neonatal outcome. It has also been shown that there has been a large increase in the number of multiparous patients in this teenage population.

Abstract
Using histological parameters with high recognition reliability, we retrospectively analyzed all newly diagnosed patients under the age of 16 years (n = 100) with brain and spinal cord tumors presenting to the National Neuroscience Centres of the Richmond and Beaumont Hospitals, Dublin, Ireland, between 1985 and 1990, allowing analysis of 5-year survival in all cases. Tumor histology was reviewed by two neuropathologists blinded to previous histological diagnosis and to the site of lesion. We found that certain histological features such as very low cell density and microcyst formation had a positive effect on prognosis. Mitoses and pleomorphism had a negative effect on prognosis, whereas necrosis and meningeal involvement had no effect on prognosis. It is suggested that identification of reliably recognized histological features rather than assignation of tumors to particular diagnostic categories may be a more reliable predictor of tumor behavior in the pediatric age-group.

Abstract
In the absence of specific dose equivalency data, the aim of this study was to compare the clinical results during the cross-over from menopausal urinary products (human menopausal gonadotrophin; HMG) to recombinant follicle stimulating hormone (FSH) follitrophin beta (FSHr) in order to determine whether the manufacturer's recommendation for equivalence of ampoule to ampoule (50 IU FSHr:75 IU HMG) would prove clinically correct. A total of 353 consecutive in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment cycles was studied between 1st September 1996 and mid-February 1997. This included cycles in the last 191 women receiving HMG and the first 162 taking FSHr. All were down-regulated using a gonadotrophin releasing hormone (GnRH) agonist long protocol method from day 1 of the cycle. Greater efficacy was seen in the HMG group in terms of days of stimulation required, need to increase dosage, cycle discontinuation, number of follicles punctured, the numbers of oocytes retrieved and their quality. The hormonal response to stimulation assessed by oestradiol concentrations on days 5, 8 and day of human chorionic gonadotrophin (HCG) was significantly lower in the FSHr group. The ratio of oestradiol per follicle and per oocyte was significantly lower in the FSHr group. There was a highly significant increase in cost with FSHr therapy. Clinical pregnancy rates were 14% per cycle with FSHr and 20% per cycle with HMG.

Abstract
OBJECTIVE To assess the role of 24-hour ambulatory blood pressure measurement in the mid-second trimester as a predictive test for the development of hypertension in pregnancy. DESIGN Prospective intervention. SETTING The Rotunda Hospital, Dublin. PARTICIPANTS One thousand one hundred and two healthy primigravid women. INTERVENTION 24-hour ambulatory blood pressure measurement at 18 to 24 weeks of gestation. MAIN OUTCOME MEASURES The development of pre-eclampsia or gestational hypertension. RESULTS A total of 1048 women had sufficient readings to be included in the final analysis. Of these, 23 (2.2%) developed pre-eclampsia, 64 (6.1%) developed gestational hypertension and 961 (91.7%) remained normotensive. Significantly higher ambulatory blood pressures were recorded in both the pre-eclamptic and gestational hypertensive group compared with the normotensive group. In addition, the gestational hypertensive group had significantly higher clinically measured blood pressure compared with the normotensive group. There were no differences between the pre-eclamptic and the gestational hypertensive group for any of the blood pressure parameters analysed. The best overall predictor for pre-eclampsia was 24-hour mean diastolic pressure which using a cutoff level of 71 mmHg gave a test with a sensitivity of only 22% and a positive predictive value of 15%. CONCLUSION Because the absolute differences are small and the overlap between the hypertensive and normotensive groups large, ambulatory blood pressure measurement, in a healthy primigravid population, between 18 and 24 weeks of gestation is not a useful predictor of hypertension.

Abstract
Recombinant human interleukin-2 (rHuIL-2) has been metabolically labeled with 14C amino acids in Escherichia coli and affinity purified on a rHuIL-2 receptor affinity column. The radiolabeled molecule had a specific radioactivity of 238 dpm/unit and the identical amino acid sequence and biological activity as unlabeled rHuIL-2. In this study, we used this labeled [14C(U)]rHuIL-2 and commercially available [125I]rHuIL-2 (identical in sequence to the [14C(U)]rHuIL-2) to compare the mass balance, pharmacokinetics, and disposition in cynomolgus monkeys. After a single intravenous bolus dose of 4 x 10(5) units/kg, serum samples were collected for 7 days and examined for biological activity, total radioactivity, and by molecular size exclusion chromatography. Urine and feces were analyzed for total radioactivity. When analyzed for biological activity, both [14C(U)]- and [125I]rHuIL-2 exhibited the following pharmacokinetic parameters: terminal elimination half-life of 1-2 hr, AUC0-infinity ranged from 2005 to 4659 units x hr/ml, clearance was 90-200 ml/hr/kg, and volume of distribution ranged from 103 to 163 ml/kg. Comparison of the pharmacokinetic profiles of the two radiolabels were very different from bioactivity, in that the elimination half-lives for radioactivity were approximately 8 days and 10 hr for [14C(U)]- and [125I]rHuIL-2, respectively. We conclude that the [14C(U)]rHuIL-2 was metabolized to constituent amino acids and recycled into newly synthesized proteins from our size exclusion chromatography studies.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The Kilkenny Health Project was a community research and demonstration programme which aimed to reduce risk of cardiovascular disease in a county in the south-east of Ireland with a total population of approximately 70,000. The health promotion programme was carried out in Kilkenny from 1985 to 1992. Outcome evaluation was by means of population surveys of independent samples of men and women aged 35 to 64 years in Kilkenny (n approximately 800) and in the reference county (n approximately 600) in 1985/1986 and in 1990/1991. Survey methods for health behaviour questionnaires and risk factor measurements were similar to those of the WHO MONICA Project. Mean systolic blood pressure (SBP) declined significantly (P < 0.01) in men and women in both counties, from 144.0 by 5.4 mmHg and from 143.2 by 5.4 mmHg in men and from 139.5 by 7.7 mmHg and from 136.5 by 6.6 mmHg in women in the intervention and reference counties. The prevalence of hypertension declined from 23.1% by 2.8% and from 26.1% by 6.0% in men in the two counties. Prevalence declined from 24.1% by 6.2% (P < 0.05) in women in the intervention county but was unchanged, increasing by 0.5% from 17.5%, in women in the reference county. Mean serum total cholesterol declined from 6.04 mmol.l-1 by 0.09 mmol.l-1 and from 6.00 by 0.44 mmol.l-1 (P < 0.01) in men and from 6.01 by 0.36 (P < 0.01) and from 5.90 by 0.31 (P < 0.01) in women in the intervention and reference counties, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The general practitioners employing all 102 nurses known to be practising as practice nurses in the Republic of Ireland were sent a questionnaire for completion anonymously. A response rate of 51% was obtained. Practices employing practice nurses were found to be mostly single handed (28/52) in a town/rural setting (39/52) and participating in the General Medical Services (GMS) Scheme (49/51)*. A substantial minority of practices (16/51)* derived more than 75% of their income from the GMS. Eighty five percent of practices felt that their practice "gained or would gain financially" through the employment of a practice nurse. (* = one non-respondent)

Abstract
All 102 nurses known to be practising as practice nurses in the Republic of Ireland were sent a questionnaire for completion anonymously. A response rate of 56% was obtained. Over half the respondents had commenced practice nursing since the new General Medical Services contract in 1989 following a career break, the median duration of which was 5.5 years. Two thirds had completed midwifery training but only one was a qualified Public Health Nurse. An examination of the tasks performed by the respondents suggests that Irish practice nurses are already filling an extended role beyond their treatment room duties with 46% involved in smoking counselling, 74% in counselling on cholesterol and 37% involved in asthma care. Nurses providing antenatal care or taking cervical smears were not, however, more likely to have completed midwifery training.

Abstract
While the histological grade of a renal cell carcinoma is of prognostic significance there is poor concordance amongst pathologists in the use of these grading systems. Many grading systems have been described, but none has achieved widespread acceptance. The objective of this study was to assess the degree of interobserver variation amongst four experienced pathologists in their use of four commonly applied grading systems. The pathologists reviewed a series of 88 cases of renal cell carcinoma. Grades were detailed on a proforma which consisted of a breakdown of each grading system. Cohen's kappa was calculated for each pair of observers for each system. The mean kappa scores for each system were compared using the Tukey honestly significant differences method. Mean kappa was highest for the grading system of Syrjanen and Hjelt and this grading system also had a higher mean kappa than two of the other systems tested. The most striking feature of the results was the degree to which the pathologists differed in their assessments. The grading system of Syrjanen and Hjelt was shown to be subject to less interobserver variability than other commonly used classifications and we are of the opinion that it should become the standard method.

Abstract
The aim of this study was to establish the effect of treating neonates' umbilical cords with chlorhexidine 0.5% in alcohol 70% on cord separation time and to observe the clinical and microbiological consequences of not treating the cords of healthy neonates. The treated group contained 466 babies whose cords were treated with chlorhexidine, 424 babies were not treated. Microbiological colonisation patterns of the cords of babies in both groups were monitored both for purposes of this investigation and to ensure that no untoward consequences resulted from non-treatment. The research showed that treatment prolonged separation time by 1.7 days, which was significant at the level of p = 0.000, and that normal colonisation was delayed in the treated group.

Abstract
E2F is a mammalian transcription factor that appears to play an important role in cell cycle regulation. While at least two proteins (E2F-1 and DP-1) with E2F-like activity have been cloned, studies from several laboratories suggest that additional homologs may exist. A novel protein with E2F-like properties, designated E2F-2, was cloned by screening a HeLa cDNA library with a DNA probe derived from the DNA binding domain of E2F-1 (K. Helin, J. A. Lees, M. Vidal, N. Dyson, E. Harlow, and A. Fattaey, Cell 70:337-350, 1992). E2F-2 exhibits overall 46% amino acid identity to E2F-1. Both the sequence and the function of the DNA and retinoblastoma gene product binding domains of E2F-1 are conserved in E2F-2. The DNA binding activity of E2F-2 is dramatically enhanced by complementation with particular sodium dodecyl sulfate-polyacrylamide gel electrophoresis-purified components of HeLa cell E2F, and anti-E2F-2 antibodies cross-react with components of purified HeLa cell E2F. These observations are consistent with a model in which E2F binds DNA as a heterodimer of two distinct proteins, and E2F-2 is functionally and immunologically related to one of these proteins.
