Using multivariate analyses and GIS to identify pollutants and their spatial patterns in urban soils in Galway, Ireland.

Galway is a small but rapidly growing tourism city in western Ireland. To evaluate its environmental quality, a total of 166 surface soil samples (0-10 cm depth) were collected from parks and grasslands at the density of 1 sample per 0.25 km2 at the end of 2004. All samples were analysed using ICP-AES for the near-total concentrations of 26 chemical elements. Multivariate statistics and GIS techniques were applied to classify the elements and to identify elements influenced by human activities. Cluster analysis (CA) and principal component analysis (PCA) classified the elements into two groups: the first group predominantly derived from natural sources, the second being influenced by human activities. GIS mapping is a powerful tool in identifying the possible sources of pollutants. Relatively high concentrations of Cu, Pb and Zn were found in the city centre, old residential areas, and along major traffic routes, showing significant effects of traffic pollution. The element As is enriched in soils of the old built-up areas, which can be attributed to coal and peat combustion for home heating. Such significant spatial patterns of pollutants displayed by urban soils may imply potential health threat to residents of the contaminated areas of the city.

Seasonal and spatial distributions of tributyltin in surface sediment of the Tolka Estuary, Dublin, Ireland.

Aquatic pollution by tributyltin (TBT) is of concern because of its high toxicity to marine life. TBT loadings of estuarine sediments may remain elevated because of long flushing times in estuaries due to their enclosed physicality. The Tolka Estuary, Co. Dublin, Ireland, is a typical Irish urban estuary. It has a significant pollution loading. The results of 12 months' analysis of TBT spatial and temporal distributions in this estuary are presented in this paper. Data from a total of 10 sample points are presented. The concentrations of TBT in the sediment were analysed using differential pulse polarography. Significant seasonal and spatial trends in TBT distribution were observed over the 12-month period. TBT concentrations ranged from 0.1 ppb in winter to 8.6 ppb in summer with a 1.5 ppb average. Organic matter (OM) concentrations of sediment exhibited similar seasonal trends and a positive correlation between OM and TBT distributions was observed.

Antidepressant prescribing and suicide rate in Northern Ireland.

PURPOSE: Although antidepressants are the most commonly used treatment for depressive illness, there is uncertainty if their use is associated with a reduction in suicide rate. Antidepressant prescribing in Northern Ireland has increased over fivefold in the decade 1989-1999. The authors sought to explore whether this increase was associated with a reduction in suicide rate taking into account social and political factors thought also to have an influence on suicide. MATERIALS AND METHODS: Factors that have been suggested to influence suicide were entered into a linear regression with frequency of suicide and undetermined deaths (referred to as suicide rate) as the dependent variable. The above factors were antidepressant prescribing, unemployment rate, household alcohol expenditure and persons charged with terrorist offences. The rise in younger suicides, in recent decades, suggests this analysis should be carried out separately for younger (less than 30 years) and older (30 years and above) suicides separately. The predictors in the two models are based on aggregate data for the total group. RESULT: In the younger group there was no association between antidepressant prescribing and suicide. For the older group increased antidepressant prescribing was associated with a reduction in suicide rate over the 10 years of the study. CONCLUSION: Increasing antidepressant prescribing appears to be an effective strategy for reducing suicide. This has been demonstrated in older individuals.

"The walls were so damp and cold" fuel poverty and ill health in Northern Ireland: results from a housing intervention.

This article reports the findings from an evaluation of a fuel poverty programme in the Armagh and Dungannon Health Action Zone in Northern Ireland. Focusing on a rural community, it adds to the debate surrounding the hidden nature of rural fuel poverty. As part of the programme, energy efficiency measures, including some central heating systems, were installed in 54 homes. Surveys were conducted both pre and post intervention and analysed to assess any changes. The programme demonstrated that energy efficiency intervention can lead to improvements in health and well being, increased comfort levels in the home and a reduction in the use of health services, therefore having potential cost savings for the NHS. Some households, however, remain in fuel poverty after having full central heating installed, reflecting the significant contribution of low income on the production of fuel poverty. The article concludes by suggesting that interventions in this area require commitment from multiple sectors of society, including health professionals and local communities.

Salmonella surveillance in raw and cooked meat and meat products in the Republic of Ireland from 2002 to 2004.

The food industry, under the regulation of the Department of Agriculture and Food (DAF) in the Republic of Ireland, is required to undertake all microbiological testing in relation to zoonoses control, in laboratories approved by DAF. These laboratories submit a monthly report of all tests undertaken, together with all presumptive Salmonella isolates for confirmation, typing and storage to the Central Veterinary Research Laboratory (CVRL). Details of Salmonella tests on 110,229 raw and 25,189 cooked meat samples from 25 laboratories were recorded over the 3-year period 2002-2004. Salmonella spp. were isolated from 1.0% of the 110,229 raw meat samples and 0.1% of the 25,189 cooked meat samples tested. The percentage of raw meat samples contaminated with Salmonella decreased over the three-year period from 1.2% to 0.9%. There was no seasonal trend in the isolation of Salmonella from any of the meats or meat products. Recoveries of the organism were highest for turkey and chicken meats at 3.1% and 2.8%, respectively, followed by porcine meats at 2.1%. The recoveries were much lower for ovine meats and meat products at 0.2% and bovine meat and meat products at 0.16%.

A comparison of paediatric soccer, gaelic football and rugby injuries presenting to an emergency department in Ireland.

OBJECTIVES: Children presenting with sport related injuries (SRIs) as a result of soccer, rugby and gaelic football are frequently seen in an emergency medicine (EM) setting in Ireland. A comparison of the demographics of injuries in these three sports has however not previously been performed. The purpose of this study was to provide up-to-date data on the nature of these SRIs. METHOD: Data was collected retrospectively on all children (<17 years of age), injured in these three sports, presenting to an emergency medicine department over 6 months, and was entered into a database for analysis. RESULTS: Retrospective analysis was performed on 23,000 charts, and 409 SRIs were identified over a 6-month period. None of the children reported using any form of protective gear, and 27% reported a previous presentation to the emergency department with a SRI. Most injuries were as a result of soccer (56%), with 24% occurring in gaelic football, and 20% occurring in rugby. The predominant mechanism of injury was different in each sport, in soccer-falls (38%), in gaelic football-collisions with objects (balls) (37%), and in rugby-collision with persons (55%). Although the predominant type of injury in soccer and gaelic football was a fracture, accounting for 50% and 42% of injuries, respectively, in rugby however, skin/soft tissue injuries presented more commonly, accounting for 44% of injuries. When the general site of injury was investigated, the upper limb accounted for the majority of SRIs in each sport. In the management of SRIs, oral analgesics were prescribed in 50%, however, it was observed that no use was made of topical, intramuscular or rectal analgesic routes of administration. In addition it was observed that RICE/general injury advice was given in only 27%, physiotherapy was requested in 2%, and no injury prevention advice was given to any child. Overall, 8% required admission. CONCLUSIONS: The data provided from this study may raise awareness of the nature of SRIs affecting children in each of these three sports, and may be useful in formulating much needed injury prevention strategies.

Population characteristics of traffic accident-related deaths in Japan and Ireland, 1950-2000.

To compare epidemiological characteristics of traffic accidents in Japan and Ireland, we analyzed mortality and the negative effect on life expectancy between 1950 and 2000 and generated a multivariate model. The characteristics were similar in the two countries: The time trends showed an increase in mortality followed by a decrease. The mortality rates were about 13 and 5/100,000 for males and females, respectively, in 2000. Correlation coefficients for sex were over 0.9. Age distribution obeyed the natural logarithm regularity. The negative effect on life expectancy was about 0.34 year for males, and 0.13 year for females. The economic level was positively associated with mortality, whereas "number of vehicles owned" was associated negatively. In conclusion, we can take advantage of the broad consistencies in these two countries when we draw up an intervention strategy. Any preventive strategy should be directed to the young, particularly males.

Soil carbon stocks and changes in the Republic of Ireland.

The soil carbon (C) stock of the Republic of Ireland is estimated to have been 2048 Mt in 1990 and 2021 Mt in 2000. Peat holds around 53% of the soil C stock, but on 17% of the land area. The C density of soils (tCha(-1)) is mapped at 2 km x 2 km resolution. The greatest soil C densities occur where deep raised bogs are the dominant soil; in these grid squares C density can reach 3000 tCha(-1). Most of the loss of soil C between 1990 and 2000-up to 23 MtC (1% of 1990 soil C stock)-was through industrial peat extraction. The average annual change in soil C stocks from 1990 to 2000 due to land use change was estimated at around 0.02% of the 1990 stock. Considering uncertainties in the data used to calculate soil C stocks and changes, the small average annual 'loss' could be regarded as 'no change'.

Survey of operating theatre ventilation facilities for minimally invasive surgery in Great Britain and Northern Ireland: current practice and considerations for the future.

Increasing use of minimally invasive surgery (MIS) and other invasive procedures has raised the question of what ventilation facilities are appropriate for such procedures to prevent infection. The Hospital Infection Society (HIS) Working Party on Infection Control in Operating Theatres undertook a survey of practice in Great Britain and Northern Ireland on the ventilation facilities provided for a variety of MIS and other procedures. Five hundred and fifty questionnaires were forwarded to HIS members, and 186 (39%) replies were received. Fifty-eight percent were from district general hospitals (DGHs). Designated theatres for orthopaedic surgery (although not necessarily ultraclean ventilated theatres) were available in more than 80% of hospitals, with approximately 50% of hospitals having designated theatres for a variety of other surgical subspecialities. Approximately two-thirds of urological procedures were performed in conventionally ventilated operating theatres. Most radiological procedures were performed in non-ventilated theatres or treatment rooms. In around half of the DGHs and university/referral hospitals, orthopaedic MIS procedures such as arthroscopy were performed in ultraclean ventilated theatres. This survey revealed considerable variation in the use of conventionally ventilated theatres and ultraclean ventilated theatres. In particular, many radiological and anaesthetic procedures are performed in treatment rooms or ventilated rooms with less than 20 air changes per hour. Whilst it is not clear whether this is acceptable practice given current knowledge, large-scale clinical trials to determine what standards of ventilation are appropriate to minimize infection for these types of procedures would be difficult to conduct. Research is needed on the relative risk of airborne infection for a variety of procedures, including whether all prosthetic implant procedures should be carried out in ultraclean ventilated theatres, as infection associated with implants is often of airborne origin and of considerable clinical significance.

Lung cancer mortality predictions for Ireland 2001-2015 and current trends in North Western Europe.

UNLABELLED: PURPOSE AND METHODOLOGY: Poisson regression models of Irish lung cancer mortality data for the years 1954-2000 were used to predict European age standardized mortality rates (EASMRs) and numbers of deaths for the period 2001-2015. Predictions for the whole population and for the age group 0-64 years were the main focus of this analysis. The models employed in this analysis were written for the STATA 6.0 STATISTICAL PACKAGE FOR WINDOWS. Linear models were applied, in general, to upward trends and log-linear models to downward trends. RESULTS: For males of all ages, EASMRs are expected to fall significantly from 59.7 per 100,000 person years (100,000 PY(-1)) in 2000 to 47.2 in the period 2011-2015. Female EASMRs are expected to fall from 28.3 100,000 PY(-1) in 2000 to 27.8 in 2011-2015. The EASMR for males under 65 years of age is predicted to continue its decline from 20.6 100,000 PY(-1) in 2000 to 11.7 in 2011-2015. The rate for females in this same age group is predicted to decline from 10.7 100,000 PY(-1) in 2000 to 7.0 in 2001-2015. Recent lung cancer trends In Ireland were also compared to other countries in North Western Europe.

Zinc concentrations in marine macroalgae and a lichen from western Ireland in relation to phylogenetic grouping, habitat and morphology.

Zinc concentrations in 19 species of marine macroalgae and a lichen from western Ireland (Spiddal, Co. Galway) were analysed by atomic absorption spectrophotometry. Algae were collected from a single site but occupied different shore levels and belonged to distinct phylogenetic groupings and to different (previously recognised) morphological groups. Concentrations ranged from 15-115 microg g(-1) dry weight. The greatest variation in concentration occurred amongst the red algal species, containing both maximum and minimum concentrations. Zn concentrations in brown and green algae were generally lower than those in red algae. When grouped according to thallus morphology, thin, branched sheets (which consisted mainly of red algae) contained the highest Zn concentrations. In filamentous algae, Zn levels were higher than in thick-leathery or coarsely branched algae. However, all green algal species examined had similar Zn concentrations, despite their different morphologies. In brown algae, the highest Zn levels were detected in mid-shore fucoids (Fucus vesiculosus and Fucus serratus), while thicker, subtidal and low-shore brown algae (Laminaria digitata, Halydris siliquosa) exhibited lower Zn concentrations. The lowest Zn concentrations were detected in high-intertidal species (Fucus spiralis, Pelvetia canaliculata), the only marine lichen examined (Ramalina siliquosa) and a red crustose alga (Corallina officinalis). In all morphological groups, red algal representatives contained relatively higher levels of Zn, the exception being Corallina officinalis. Zn levels in 4 species from a second, estuarine site in Galway Bay exhibited the same relative differences amongst species, but were all consistently higher than in algae from Spiddal. It is concluded that Zn accumulation in macroalgae is closely related to ecological growth strategies, following a functional-form model. However, the phylogenetic origin of species which determines carbohydrate and phenol composition, and responses to ambient environmental conditions ultimately determine, the availability of binding sites for polyvalent cations.

An assessment of the pollutant status of surficial sediment in Cork Harbour in the South East of Ireland with particular reference to polycyclic aromatic hydrocarbons.

Surface sediment from three polluted sites within Cork Harbour, Ireland, and from a relatively clean reference site were collected and analysed for polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), brominated flame retardants (BFRs), organotins (OTs), and heavy metals. PAHs were determined to be the most abundant class of contaminant. Concentrations of the sum (Sigma) of the 21 PAHs measured from the Harbour sites (2877.70 ng g(-1), 1000.7 ng g(-1) and 924.40 ng g(-1) dry weight respectively) were significantly higher than that of the sediment from the reference site (528.30 ng g(-1) dry weight). An inner harbour site, Douglas being the more contaminated of the three harbour sites. A similar pattern was observed with the other contaminants however, these compounds, with the exception of the heavy metals, all tended to be detected at concentrations on or below detection limits.

A feminist exploration of Traveller women's experiences of maternity care in the Republic of Ireland.

OBJECTIVE: to explore Traveller women's experiences of maternity care so that their needs might be identified and perceptions of helpful responses elicited. DESIGN: feminist research methodology using unstructured non-directive interviews. SETTING: community setting in the Republic of Ireland. PARTICIPANTS: snowball sample of 13 Traveller women aged 19-42 years. Each had experienced between two and eight pregnancies. FINDINGS: a fluid concept of culture affected Traveller women's expectations and negotiation of maternity care. The essential nature of familism, socialisation and religious beliefs, and the particular emphasis placed upon peer support, reflected cohesive and supportive aspects of culture. The concept of 'possessive individualism' was portrayed as conflicting with contraceptive use, the uptake of preventive care and women's reporting of mental-health problems. Majority norm expectations of breast feeding, husband participation and 'rooming in' were culturally unacceptable. Political and structural factors, such as the direct discriminatory barriers created by general practitioner services, indirect discrimination arising from dysfunctional communication and control of information, poor housing and lack of public transport were the basic causes of inequity of access to care. IMPLICATIONS FOR PRACTICE: midwives are challenged to respond sensitively to cultural preferences, meet informational needs and act as political advocates in efforts to improve maternity care experiences for Traveller women.

Implementing objective structured clinical skills evaluation (OSCE) in nurse registration programmes in a centre in Ireland: a utilisation focused evaluation.

This paper presents findings from a research study of two objective structured clinical skills evaluation (OSCE) processes that were used in the new BSc. in General and Psychiatric Nursing Registration programmes offered in an Institute of Technology in the south west of Ireland. OSCEs, which have gained widespread acceptance throughout the western world as valid academic measures of nursing competence has yet to be established in this country. This research aimed to evaluate the process and outcomes of OSCE from the perspective of the major stakeholder groups: first and second year nursing students, lecturers, clinical placement coordinators and assessors. A utilisation focussed evaluation approach was adopted which values the opinions and experiences of stakeholders. It is intended to use the findings to develop the validity and quality of the OSCE assessment. The OSCE process was found to have a positive impact on all stakeholders. OSCEs were perceived to be a meaningful and fair form of assessment. Students identified that they felt more prepared for and more confident about forthcoming placements. The OSCE process was, however, perceived to be a stressful experience and requires considerable preparation effort by students and academic staff. Mature students claimed that more practice effort was required but also felt more prepared for placements and achieved higher OSCE scores.

Spatial relationship between Mycobacterium bovis strains in cattle and badgers in four areas in Ireland.

We investigated whether strains (restriction fragment length polymorphism, RFLP-types) of Mycobacterium bovis isolated from badgers and from cattle clustered among and within four areas in Ireland. The spatial scan test and nearest-neighbor analysis were used as the spatial cluster-detection techniques. In addition, for each of the major strains, associations between the distance to badger setts and the "centroid" of the cattle farm were assessed in a logistic model. Overall, between September 1997 and May 2000, 316 and 287 M. bovis samples, from badgers and cattle, respectively, were strain-typed. The distribution of strains in badgers, and separately in cattle, differed among areas. Within each of the four large areas, badgers and cattle tended to have similar strains; this is consistent with the sharing of M. bovis strains within an area. In more detailed within-area analyses, some spatial clusters of M. bovis strains were detected, separately, in both cattle and badgers. Almost half of the infected badger setts with a specific strain were located outside of the "detected" clusters. There was no association between the number of infected badgers with a specific M. bovis strain within 2 or 5 km distances to cattle herds, and the risk of the same strain in cattle. We speculate about the dynamic nature of badger movements, as an explanation for the absence of more clusters of most of the strains of M. bovis isolated from badgers, and its impact on trying to study transmission of M. bovis between cattle and badger.

A study of helminth parasites in culled cows from Ireland.

The objective of this study was to determine the prevalence and intensity of gastrointestinal nematode, lungworm and liver fluke infection in culled cows in Ireland. Abomasa, colorectal contents and livers were collected from 30 to 68 culled beef and dairy cows during autumn 2002 and summer 2003, respectively. Ostertagia ostertagi were found in the abomasa of only three (10%) cows sampled in autumn and in 38 (57%) cows examined in summer. The majority of positive animals had low burdens of O. ostertagi but a few individuals in the group sampled during the summer had a moderate infection (5000-10,000 adult worms). A proportion of the cows in the summer group were also co-infected with small numbers of Trichostrongylus axei. Cooperia oncophora predominated in the recoveries from the larval cultures although O. ostertagi were also recovered. The overall prevalence of Dictyocaulus viviparus was 14%, based on larval identification in faecal samples. Liver fluke, or varying degrees of pathology attributable to Fasciola hepatica, were present in 65% of the livers. The results of this study extend those of previous workers, which were largely limited to dairy cows alone and which focussed on gastrointestinal nematodes and did not include simultaneous infections with lungworm and liver fluke. It was concluded, from the level of polyparasitism evident in this study, that adult cattle should be considered in preventative approaches to bovine helminthosis.

A dosimetric intercomparison of brachytherapy facilities in Ireland, Scotland and the North of England.

BACKGROUND AND PURPOSE: A dosimetric intercomparison of brachytherapy remote afterloading units in Ireland, Scotland and the North of England has been carried out involving 9 radiotherapy centres, and sampling 5 HDR and 6 LDR units. MATERIALS AND METHODS: Absolute calibrations have been performed in air on both HDR and LDR sources. The results are expressed in terms of a ratio of local to calibrated value. Frequency distributions were obtained for the multi-source LDR units by individually measuring each source. Using these distributions the effect of non-uniform source strength on the dose rate at Manchester point A was assessed for a typical clinical brachytherapy insertion for carcinoma of the cervix. Both frequency and dose rate distribution curves were modeled using normal statistics and characterised in terms of the mean (mu) and standard deviation (sigma). RESULTS: Evaluation of the HDR units indicated a mean ratio of 1.008 (+/-0.01) while for LDR the mean ratio was 0.997 (+/-0.02). The LDR frequency distributions demonstrated a variation of sigma values extending from 1.4 to 3.0% of mu. It was shown that this non-uniformity in source strength introduced an uncertainty in the treatment planning process of between 0.8 and 1.8% when compared to the assumption of uniform source strength. CONCLUSIONS: The results of this intercomparison indicate dosimetric consistency between centres for both LDR and HDR units. The distribution of LDR source strengths were within expected limits and the resultant dose rate distributions were considered clinically acceptable.
