RESUMO
This second part explores perceptions and understanding of clinical performance, turnaround, and costs for printed titanium implants or plates in common procedures, evaluating both 'in-house' and 'outsourced' CAD-CAM pathways. A cross-sectional study, supported by the British Association of Oral and Maxillofacial Surgeons (BAOMS) and a national trainee-led recruitment team, was conducted over 14 weeks. A total of 132 participants took part (demographic data is reported in Part I). For fibular-flap mandibular reconstruction, most participants (69% - 91%) perceived printed titanium as superior to intraoperatively or preoperatively hand-bent plates for surgical duration, accuracy, dental restorability, and aesthetics. There was less agreement about complications and plate-failure risks. Most perceived printed plates to be superior to traditional wafer-based maxillary osteotomy for surgical duration (61%) and maxillary positioning (60%). For orbital floor repair, most perceived improvements in surgical duration (83%, especially higher-volume operators p=0.009), precision (84%), and ease of placement (69%). Rarely (less than 5%) was any outcome rated inferior to traditional techniques for any procedure. Perceived turnaround times and costs were variable, but the greatest consensus was for two-segment fibular-flap reconstructions and orbital floor repair. Industry estimates were generally consistent between two company representatives, but manufacturing-only costs differed when using in-house (departmental) designers. Costs and turnaround times are questionable barriers since few understand 'real-world' figures. Designing in-house can dramatically alter costs. Improved accuracy and surgical duration are common themes but biomechanical benefits are less-well understood. This study paints a picture of the potentially routine applications and benefits of printed titanium, capacity for uptake, understanding amongst surgeons, and areas for improvement.

BACKGROUND: Economic recessions are often accompanied by increased levels of psychological distress and suicidal behaviour in affected populations. Little is known about the experiences of people seeking help for employment, financial and benefit-related difficulties during recessions. We investigated the experiences of people struggling financially in the aftermath of the Great Recession (2008-9) - including some who had self-harmed - and of the frontline support staff providing assistance. METHODS: Interviews were conducted with three groups of people in two cities: i) people who had self-harmed due to employment, financial or benefit concerns (n = 19) ('self-harm'); ii) people who were struggling financially drawn from the community (n = 22), including one focus group) ('community'); iii) and frontline staff from voluntary and statutory sector organisations (e.g., Job Centres, Debt Advice and counselling agencies) providing support services to the groups (n = 25, including 2 focus groups) ('service providers'). Data were analysed using the constant comparison method. RESULTS: Service provision was described by people as confusing and difficult to access. The community sample reported considerably more knowledge and access to debt advice than the participants who had self-harmed - although both groups sought similar types of help. The self-harm group exhibited greater expectation that they should be self-reliant and also reported lower levels of informal networks and support from friends and relatives. They had also experienced more difficult circumstances such as benefit sanctions, and most had pre-existing mental health problems. Both self-harm and community groups indicated that practical help for debt and benefit issues would be the most useful - a view supported by service providers - and would have particularly helped those who self-harmed. CONCLUSION: Interventions to identify those in need and aid them to access practical, reliable and free advice from support agencies could help mitigate the impact on mental health of benefit, debt and employment difficulties for vulnerable sections of society.

Introduction Social context has a major influence on the detection and treatment of youth mental and substance use disorders in socioeconomically disadvantaged urban areas, particularly where gang culture, community violence, normalisation of drug use and repetitive maladaptive family structures prevail. This paper aims to examine how social context influences the development, identification and treatment of youth mental and substance use disorders in socioeconomically disadvantaged urban areas from the perspectives of health care workers. METHOD: Semi-structured interviews were conducted with health care workers (n=37) from clinical settings including: primary care, secondary care and community agencies and analysed thematically using Bronfenbrenner's Ecological Theory to guide analysis. RESULTS: Health care workers' engagement with young people was influenced by the multilevel ecological systems within the individual's social context which included: the young person's immediate environment/'microsystem' (e.g., family relationships), personal relationships in the 'mesosystem' (e.g., peer and school relationships), external factors in the young person's local area context/'exosystem' (e.g., drug culture and criminality) and wider societal aspects in the 'macrosystem' (e.g., mental health policy, health care inequalities and stigma). CONCLUSIONS: In socioeconomically disadvantaged urban areas, social context, specifically the micro-, meso-, exo-, and macro-system impact both on the young person's experience of mental health or substance use problems and services, which endeavour to address these problems. Interventions that effectively identify and treat these problems should reflect the additional challenges posed by such settings.
RESUMO
This qualitative study explored general practitioner's and practice nurse's perceptions of barriers and facilitators to the proposed transfer of diabetes care to general practice. Qualitative data were collected through five focus groups. Participants included GPs (n = 55) and practice nurses (n = 11) representing urban (44%), rural (29%) and mixed (27%) practices, in the Irish Mid-West region. Barriers and facilitators were mentioned 631 times (100%). Barriers were mentioned 461 times (73%), facilitators 170 times (27%). The most frequently identified barriers were lack of financial incentive (119/631; 19%), lack of access to secondary resources (93/631; 15%), lack of staff and increased workload (59/631; 9%) and time constraints (52/631; 8%). Identified facilitators were access to secondary care (49/631;7.8%), the holistic nature of general practice and continuity of care (48/631;7.6%). Although many are enthusiastic, there remains significant reluctance among GPs and practice nurses to take responsibility for diabetes care without addressing these barriers.

BACKGROUND: As healthcare and longevity improve and fertility rates decline, we see a demographic shift towards a predominantly elderly population. Because ageing brings its own physiological changes and complications, the need arises for practical and feasible approaches in providing the healthcare required by this population. With government strategy promoting enhanced community-based healthcare, the development of primary care infrastructure should reflect population needs. AIMS: To describe the profile of older patients attending a general practice in an underprivileged urban setting, specifically initial medical presentation, referrals for secondary care, and the medicines prescribed to them. To thereby enhance our understanding of the primary care requirements of elderly people in this setting. METHODS: The anonymised records of an older patient cohort (n=427, age>55 years) that presented to a General Practice over a 12-month period were retrospectively analysed to determine the nature of the clinical encounters, subsequent referral patterns and drugs prescribed. RESULTS: There were 3,448 discrete clinical encounters (mean=8.0 per patient), predominantly for respiratory conditions, leading to 401 issued scripts and to 216 patients being referred for secondary care. Women were referred more often than men. There was a notable need for specialised dietary advice and drug prescribing was often complex. CONCLUSION: This study provides evidence of primary care needs in an economically deprived area of an Irish city highlighting the complexity of associated prescribing and secondary care referrals in this setting.

The aberrant expression and functional activity of proteins involved in ATP production pathways may cause a crisis in energy generation for cells and compromise their survival under stressful conditions such as excitation, starvation, pharmacological treatment or disease states. Under resting conditions such defects are often compensated for, and therefore masked by, alternative pathways which have significant spare capacity. Here we present a multiplexed 'cell energy budget' platform which facilitates metabolic assessment and cross-comparison of different cells and the identification of genes directly or indirectly involved in ATP production. Long-decay emitting O(2) and pH sensitive probes and time-resolved fluorometry are used to measure changes in cellular O(2) consumption, glycolytic and total extracellular acidification (ECA), along with the measurement of total ATP and protein content in multiple samples. To assess the extent of spare capacity in the main energy pathways, the cells are also analysed following double-treatment with carbonyl cyanide p-(trifluoromethoxy)phenylhydrazone and oligomycin. The four-parametric platform operating in a high throughput format has been validated with two panels of transformed cells: mouse embryonic fibroblasts (MEFs) lacking the Krebs cycle enzyme fumarate hydratase (Fh1) and HeLa cells with reduced expression of pyrimidine nucleotide carrier 1. In both cases, a marked reduction in both respiration and spare respiratory capacity was observed, accompanied by a compensatory activation of glycolysis and consequent maintenance of total ATP levels. At the same time, in Fh1-deficient MEFs the contribution of non-glycolytic pathways to the ECA did not change.

Irritative voiding symptoms are to the urinary tract much as a cough is to the pulmonary system, that is, a nonspecific manifestation of multiple potential underlying causes. Key to the evaluation and management of patients with these symptoms is a clear understanding of the differential diagnosis, the diagnostic tests required for evaluation, and the role of specialists in diagnosis and treatment. This article outlines a general diagnostic approach for patients with irritative voiding symptoms. Treatment approaches for the diseases, as well as the initial management that may be performed in the primary care setting, are also discussed.

OBJECTIVES: The public health burden of tobacco use is shifting to the developing world, and the tobacco industry may apply some of its successful marketing tactics, such as allaying health concerns with product modifications. This study used standard smoking machine tests to examine the extent to which the industry is introducing engineering features that reduce tar and nicotine to cigarettes sold in middle- and low-income countries. STUDY DESIGN: Multicountry observational study. METHODS: Cigarettes from 10 different countries were purchased in 2005 and 2007 with low-, middle- and high-income countries identified using the World Bank's per capita gross national income metric. Physical measurements of each brand were tested, and tobacco moisture and weight, paper porosity, filter ventilation and pressure drop were analysed. Tar, nicotine and carbon monoxide emission levels were determined for each brand using International Organization for Standardization and Canadian Intensive methods. Statistical analyses were performed using Statistical Package for the Social Sciences. RESULTS: Among cigarette brands with filters, more brands were ventilated in high-income countries compared with middle- and low-income countries [χ(2)(4)=25.92, P<0.001]. Low-income brands differed from high- and middle-income brands in engineering features such as filter density, ventilation and paper porosity, while tobacco weight and density measures separated the middle- and high-income groups. Smoke emissions differed across income groups, but these differences were largely negated when one accounted for design features. CONCLUSIONS: This study showed that as a country's income level increases, cigarettes become more highly engineered and the emissions levels decrease. In order to reduce the burden of tobacco-related disease and further effective product regulation, health officials must understand cigarette design and function within and between countries.

AIMS: To determine (1) whether Australian smokers are aware of low-nitrosamine smokeless tobacco (LNSLT) products and (2) whether they would be interested in using LNSLT either as a long-term substitute for smoking or as an aid to quitting, if these products were to become legally available. METHODS: 401 daily smokers were recruited by a market research company to complete an internet questionnaire about their smoking history, knowledge of smokeless tobacco and intentions to purchase LNSLT under different scenarios. FINDINGS: Just under half (48%) indicated they were willing to buy an LNSLT product. Predictors of an interest in purchasing LNSLT were low income, poorer health, prior SLT use, belief that SLT is less harmful than cigarettes, switching to a lower tar cigarette in the past year, ever using nicotine replacement therapy products for quitting or other reasons, having made a failed cessation attempt in the previous year and not planning to quit smoking. Analysis of quitting and LNSLT purchasing intentions under different scenarios suggest that making LNSLT available at a much lower cost than smoked cigarettes while increasing taxes on cigarettes could provide a greater reduction in the number of smokers than the same tax increase alone. These results support further examination of the potential for LNSLT to reduce smoking-related harm in Australia.

OBJECTIVE: To examine levels of support for comprehensive smoke-free policies in six large Chinese cities. METHODS: Data from Wave 1 of the International Tobacco Control (ITC) China Survey (April-August 2006) were analysed. The ITC China Survey employed a multistage sampling design in Beijing, Shenyang, Shanghai, Changsha, Guangzhou and Yinchuan (none of which has comprehensive smoke-free policies in place). Face-to-face interviews were conducted with 4815 smokers and 1270 non-smokers. Multivariate logistic regression models were used to identify factors associated with support for comprehensive smoke-free policies. RESULTS: About one in two Chinese urban smokers and four in five non-smokers believed that secondhand smoke (SHS) causes lung cancer. The majority of respondents supported comprehensive smoke-free policies in hospitals, schools and public transport vehicles while support for smoke-free workplaces, restaurants and bars was lower. Levels of support were generally comparable between smokers and non-smokers. Support for comprehensive smoke-free policies was positively associated with knowledge about the harm of SHS. Respondents who worked in a smoke-free worksite or who frequented smoke-free indoor entertainment places were more likely to support comprehensive smoking restriction in bars and restaurants. CONCLUSION: Considerable support for smoke-free policies exists in these six large cities in China. Greater public education about the dangers of SHS may further increase support. Experiencing the benefits of smoke-free indoor entertainment places and/or workplaces increases support for these policies and suggests that some initial smoke-free policy implementation may hasten the diffusion of these public health policies.

BACKGROUND: Single cigarette use and its implications have rarely been studied among adults. OBJECTIVE: To assess perceptions, prevalence and correlates of single cigarette purchase behaviour and its relation to harm reduction. DESIGN: Focus group transcripts and cross-sectional data were analysed. SETTING AND PARTICIPANTS: Focus groups among convenience samples of adult smokers in two Mexican cities and a population-based sample of 1079 adult smokers from the International Tobacco Control Policy Evaluation Project in four Mexican cities. MAIN OUTCOME MEASURES: Purchase of single cigarettes last time cigarettes were bought, frequency of purchasing single cigarettes in the previous month and intention to quit in the next 6 months. RESULTS: Focus group data indicated that smokers bought single cigarettes as a harm reduction strategy. Survey data indicated that 38% of participants purchased single cigarettes in the last month and 10% purchased them the last time they bought cigarettes, with more frequent consumption among young adults and those with lower income. Purchasing single cigarettes was independently associated with the frequency of using single cigarettes to reduce consumption and, less consistently, with the frequency of being cued to smoke after seeing single cigarettes for sale. Using single cigarettes to reduce consumption was positively associated with quit intention, whereas being cued to smoke by single cigarettes was negatively associated with quit intention. CONCLUSIONS: Study results suggest that some adult Mexican smokers purchase single cigarettes as a method to limit, cut down on and even quit smoking. Nevertheless, promotion of the availability of single cigarettes as a harm reduction strategy could provide additional smoking cues that undermine quit attempts and promote youth smoking.

BACKGROUND: The International Tobacco Control (ITC) Four Country Survey (ITC-4) is a prospective cohort study designed to evaluate the psychosocial and behavioural impact of national-level tobacco control policies enacted in the Australia, Canada, the UK, and the USA. Wave 1 of ITC-4 survey was conducted between October 2002 and December 2002. Wave 2 survey was conducted between May 2003 and August 2003. OBJECTIVE: To test for individual-level predictors of smoking cessation behaviours (that is, quit attempts and smoking cessation) among cigarette smokers in the ITC Four Country Study measured between Wave 1 and Wave 2. This set of predictors will serve as the base for evaluating the added effect of tobacco control policies and other factors. METHODS: Respondents included in this study are 6682 adult current smokers in the Wave 1 main survey who completed the Wave 2 follow-up (1665 were in Canada, 1329 were in the USA, 1837 were in the UK and 1851 were in Australia). RESULTS: Factors predictive of making a quit attempt included intention to quit, making a quit attempt in the previous year, longer duration of past quit attempts, less nicotine dependence, more negative attitudes about smoking, and younger age. Lower levels of nicotine dependence were the main factor that predicted future cessation among those that made a quit attempt. CONCLUSION: Intention to quit and other cognitive variables were associated with quit attempts, but not cessation. Behavioural variables related to task difficulty, including measures of dependence, predicted both making attempts and their success. Predictors of making quit attempts and cessation were similar for each of the four countries, but there were some differences in predictors of success.

Long term exposure of skylarks to a fictitious insecticide and of wood mice to a fictitious fungicide were modelled probabilistically in a Monte Carlo simulation. Within the same simulation the consequences of exposure to pesticides on reproductive success were modelled using the toxicity-exposure-linking rules developed by R.S. Bennet et al. (2005) and the interspecies extrapolation factors suggested by R. Luttik et al. (2005). We built models to reflect a range of scenarios and as a result were able to show how exposure to pesticide might alter the number of individuals engaged in any given phase of the breeding cycle at any given time and predict the numbers of new adults at the season's end.

It is generally acknowledged that population-level assessments provide a better measure of response to toxicants than assessments of individual-level effects. Population-level assessments generally require the use of models to integrate potentially complex data about the effects of toxicants on life-history traits, and to provide a relevant measure of ecological impact. Building on excellent earlier reviews we here briefly outline the modelling options in population-level risk assessment. Modelling is used to calculate population endpoints from available data, which is often about individual life histories, the ways that individuals interact with each other, the environment and other species, and the ways individuals are affected by pesticides. As population endpoints, we recommend the use of population abundance, population growth rate, and the chance of population persistence. We recommend two types of model: simple life-history models distinguishing two life-history stages, juveniles and adults; and spatially-explicit individual-based landscape models. Life-history models are very quick to set up and run, and they provide a great deal of insight. At the other extreme, individual-based landscape models provide the greatest verisimilitude, albeit at the cost of greatly increased complexity. We conclude with a discussion of the implications of the severe problems of parameterising models.

UNLABELLED: Assessment of paramedic endotracheal intubation (ETI) performance often does not account for varied clinical conditions or the time required to complete the procedure. OBJECTIVE: To demonstrate the utility of patient status and time to intubation (TTI) for evaluating prehospital ETI performance. METHODS: Paramedic charts were reviewed for the period January-December 1998. Patient clinical status was defined as cardiac arrest (absence of perfusing rhythm) or non-cardiac arrest (presence of perfusing rhythm). Method, route, and success of ETI were noted. The TTI was determined as the elapsed time from on-scene arrival to securing of the endotracheal tube. Time elapsed from on-scene arrival to emergency department arrival was noted for instances of failed ETI. Statistical analysis was performed using chi-square and survival analysis (Kaplan-Meier estimator). RESULTS: Computer records were available for 26,026 patient contacts. Of 893 documented ETI attempts, 771 (86%) were successful. The ETI success rate was significantly higher (p<0.001) for cardiac arrests (551 of 591, 93.2%) than for non-cardiac arrests (220 of 302, 72.9%). Median TTIs were 5 minutes (95% CI: 5, 5) for cardiac arrests and 17 minutes (95% CI: 14, 20) for non-cardiac arrests; this difference was significant (p<0.001). For non-cardiac arrests, ETI success was significantly (p = 0.002) higher for orotracheal intubation (OTI) (168 of 214, 78.5%) than for nasotracheal intubation (NTI) (52 of 88, 59.1%). Median TTIs were 15 minutes (95% CI: 13, 17) for OTI and 25 minutes (95% CI: 23, 27) for NTI; this difference was significant (p = 0.002). For non-cardiac arrests, the difference i

BACKGROUND: Occupational stress has been implicated as an independent risk factor in the aetiology of coronary heart disease and increased hypertensive risk in a number of occupations. Despite the large number of studies into GP stress, none have employed an objective physiological stress correlate. OBJECTIVES: We conducted an exploratory study to investigate whether self-reported occupational stress levels as measured by the General Practitioner Stress Index (GPSI) were predictive of ambulatory blood pressure (ABP) using a Spacelabs 90207 in a sample of British GPs. METHOD: Twenty-seven GPs (17 males, 10 females) participated in the study. Each GP wore an ABP monitor on a normal workday and non-workday. All GPs completed the GPSI before returning the ABP monitors. Demographic data were also collected. RESULTS: Stress associated with 'interpersonal and organizational change' emerged from the stepwise multiple regression analysis as the only significant predictor of ABP, explaining 21% of the variance in workday systolic blood pressure, 26% during the workday evening and 19% during the non-workday. For diastolic blood pressure, the same variable explained 29% of the variability during the workday and 17% during the non-workday. No significant gender differences were found on any of the ABP measures. CONCLUSIONS: For the first time in GP stress research, our findings established that higher levels of self-reported occupational stress are predictive of greater ABP in British GPs. More detailed psychophysiological research and stress management interventions are required to isolate the effects of occupational stress in British GPs.

153 sociology students specified parental occupation and job status before estimating their own and their parents' overall IQ. Male subjects, as predicted, gave a higher mean self-estimated score to themselves than did female subjects (113 vs 106). Fathers were awarded higher IQ scores than mothers (114 vs 107). Male subjects who had mothers in a higher social class gave themselves the highest mean score.

In a sample of young Canadian adults, questionnaire data indicated that both unemployment and selfreported underemployment represent health risks, as defined by subjectively rated health, experienced symptoms and illness measures. While health behaviours, including substance use, diet and exercise, medical compliance and unsafe driving practices contributed independently to health outcomes, they did not explain the linkage between employment status and health. Household income, but not personal income, predicted health and mediated this relationship only in the case of symptoms. The results are discussed in terms of an expanded understanding of the socioeconomic gradient in health.
RESUMO
Emergency medical services systems and MCOs must cooperate and educate each other in order to effect delivery of reliable, high-quality emergency health care to the entire community. Shared goals are rapid access, medically appropriate care, and operational efficiency. An integrated approach is necessary in order to maintain the integrity of EMS systems. EMS systems serve as a safety net for patients with perceived emergencies. Changes in form and function should be guided by outcome studies that ensure the continued delivery of quality emergency health care services.
