Outcomes Following Bronchial Artery Embolisation for Haemoptysis in Cystic Fibrosis.

BACKGROUND: Bronchial artery embolisation (BAE) is recommended for the treatment of massive haemoptysis in cystic fibrosis (CF), but there are no randomised controlled trials of this therapy and its role in sub-massive haemoptysis is unclear. This study aimed to determine the outcomes and safety of BAE in adults with CF. MATERIALS AND METHODS: All patients with CF undergoing BAE at our centre between March 2011 and January 2015 were identified at the time of the procedure. Patient records were reviewed at hospital discharge, death or one month post-procedure (whichever was soonest). Follow-up continued to January 2016. Severity of haemoptysis was classified as: massive (>240 ml/24 h or >100 ml/day for ≥2 days), moderate-severe (>20 ml/24 h) or mild (<20 ml/24 h). RESULTS: Twenty-seven patients underwent 51 BAE procedures over a median follow-up period of 26 months (range 1-54). Ten patients (37%) required more than one BAE during the study. BAE was performed for massive haemoptysis in 18 cases (35%). Haemoptysis recurred after 31 (61%) of BAE procedures with no difference in recurrence rates between massive and sub-massive haemoptysis. Side effects were reported after 61% of procedures with chest pain the most common adverse event . Mortality after first BAE in the study was 3.9% at 30 days and 14.8% at 12 months. No significant predictors of mortality were identified. CONCLUSIONS: BAE is often effective in controlling haemoptysis but is associated with considerable morbidity and high recurrence rates.

Recommendations for improving the assessment of postgraduate dental education.

This paper makes recommendations for the improvement of assessment in postgraduate dental education. The recommendations are based on a twelve-month study conducted in 1998/99 which evaluated the strengths and weaknesses of the existing assessment systems. Evidence was taken from examination syllabi, assessments and records. Semi-structured interviews were conducted with representatives from national bodies and with trainers and trainees in the West Midlands. Strengths in parts of the system include: commitment and professional experience; commissioned work; opportunity to share experience; a monitoring framework; procedures for maintaining standards and examples of broadbased assessments. Weaknesses include: lack of assessment of quality; existence of some forms of unregulated assessment; lack of transparency and lack of clarity between training and assessment. Development is recommended in three broad areas: a competence-based model of assessment; distinguishing assessment from the analysis of educational needs and quality assurance. The introduction of a competence-based model is the most significant and is addressed in some detail. Specific proposals for consideration by national regulatory bodies and education providers include: strengthening the management of assessment; national leadership in the development of a competence model of assessment; widening the assessment base; clearer criteria for inspection; revisions to how vocational training, HO/SHO training and general professional training are assessed and training for trainers.

Assessment in postgraduate dental education: an evaluation of strengths and weaknesses.

UNLABELLED: This paper describes a study designed to evaluate assessment in postgraduate dental education in England, identifying strengths and weaknesses and focusing specifically on its relevance, consistency and cost-effectiveness. METHODS: A four-phase qualitative method was used: a mapping of current career paths, assessment policy, and issues (phase 1); more detailed studies of the practice of assessment for a range of courses, and the systemic/management perspective of assessment (i.e. quality assurance) (phases 2 and 3), and analysis and reporting (phase 4). Data were analysed from documents, interviews, group consultations and observations. RESULTS AND DISCUSSION: Five key issues may be distilled from the findings: (i) lack of formal assessment of general professional training; (ii) trainer variation in assessment; (iii) the extent to which assessments are appropriate indicators of later success; (iv) the relationship between assessment and patient care, and (v) data to assess the costs of assessment. CONCLUSION: Current assessment procedures might be improved if consideration is given to: assessment which supports an integrated period of general professional training; training for trainers and inspection procedures to address variation; more authentic assessments, based directly on clinical work and grading cases and posts, and better data on allocation of resources, in particular clinicians' time given to assessment.

A role for clinical audit and peer review in the identification of continuing professional development needs for general dental practitioners: a discussion.

The purpose of this paper is to discuss how the role of peer review and clinical audit may be used in the identification of the continuing professional development (CPD) needs of general dental practitioners (GDPs). Clinical audit and peer review are intrinsically valuable in terms of the continued professional development of GDPs. Collaborative clinical audit, in particular, can provide a framework for short course input and there are particular benefits to this combination of activities which might usefully be more widely encouraged. If open to analysis in a way which retains individual anonymity, peer review and clinical audit resumes, these could be used to inform the provision of CPD and, linked to the knowledge of audit facilitators, short courses might more closely match the CPD needs of local dentists.

Adolescents' use of tobacco, health locus of control, and self-monitoring.

This study examined the association of the traits, health locus of control, and self-monitoring with adolescents' tobacco uptake. Participants were 112 rural adolescents (12 to 19 years old, M = 15.3). Of that sample, 33% used tobacco. Tobacco users were found to score lower on the dimension of Internality and higher on the dimension of Chance, as compared with nonusers of tobacco, indicating a more external Health Locus of Control. In addition, tobacco users were lower self-monitors than were nonusers. These results suggest that adolescents who use tobacco feel less in control of their lives in relation to nonusers, believe that chance plays a larger role in their health, and believe they may be unable to monitor and adapt their communication to achieve positive outcomes.

Influence of age, sex, and balance on mature skipping by children in grades K-8.

This study examined the contributions of age, sex, and balance on maturity of skipping by children in Grades K-8. The subjects were 379 boys and 337 girls (ages 4-14 years) enrolled in a medium-size school system in southeastern Maine. Each subject was individually assessed on skipping as well as static and dynamic balance. To assess the independent statistical contributions of age, sex, static balance, and dynamic balance within each grade, data were subjected to multiple regression analysis. Development of mature form in skipping was related to balance in two isolated but unaccountable instances.

A comparison of different approaches to promote community-wide dietary change.

BACKGROUND: Because public health education funds are limited, it is important to determine which methods are most effective for promoting healthy lifestyles to communities. We conducted interventions in two communities to further examine the effectiveness of various educational approaches for communicating the "1% Or Less" message to switch from high-fat (whole or 2%) to low-fat (1% or fat-free) milk. METHODS: One intervention used public relations and community-based educational activities in supermarkets, schools, worksites, and other community settings. The other used paid advertising in the absence of other programming. We used telephone surveys and supermarket milk sales data, collected before and after each campaign and in a comparison community, to determine changes in milk-usage patterns. RESULTS: After the campaign of community-based educational programs and public relations activities, the proportion of high-fat milk drinkers who reported drinking low-fat milk was 19.6% compared with 6.8% for the comparison city (p<0.0001). After the advertising-only campaign, 12.8% of high-fat milk drinkers reported drinking low-fat milk (p<0.01). Although supermarkets experienced increases in low-fat milk sales after both campaigns, the results were not statistically significant. CONCLUSIONS: The results show how well-designed public relations activities can attract news coverage and provide further evidence that such coverage can be an important component of health-promotion campaigns. Although the use of paid advertising in the absence of other media or programming appeared to change milk-drinking habits, the results were not sustained after the ads stopped airing.

Grip-strength performances by 6- to 19-yr.-old children with and without hearing impairments.

86 children and youth enrolled at a residential school for the deaf were matched with 86 children and youth with normal hearing (by age, sex, height, weight, and hand preference) from four public schools. Each participant's grip strength was tested with a calibrated hydraulic dynamometer set at the second position. No significant between-group differences were observed. The authors attributed the similar between-group performances to the equal opportunities for participation in sport and physical education in this residential school.

Using mass media to promote healthy eating: A community-based demonstration project.

BACKGROUND: Many question whether mass media, in the absence of other programming, can produce significant and sustained behavior change. METHODS: The 1% Or Less campaign in Wheeling, West Virginia (population 35,000), used paid advertising and public relations to encourage members of one community to switch from whole or 2% milk (high-fat milk) to 1% or fat-free milk (low-fat milk). The study used a quasi-experimental research design with one intervention city and one comparison city. The effectiveness of the campaign was evaluated by collecting milk sales data from supermarkets and conducting pre- and post-intervention telephone surveys in intervention and comparison cities. RESULTS: In the intervention city, low-fat milk sales increased from 29% of overall milk sales before the campaign to 46% of sales in the month following the campaign. The increase was maintained at the 6-month follow up. According to the telephone surveys, 34.1% of high-fat-milk drinkers reported switching to low-fat milk in the intervention community compared with 3.6% in the comparison community (z = 13.1, P < 0.0001). CONCLUSIONS: A media-only approach was sufficient to encourage a significant proportion of the people in one community to alter the dietary habit targeted by the intervention.

Continuing education courses in dentistry: assessing impact on practice.

INTRODUCTION: In the context of movement towards mandatory continuing dental education, this paper describes how a delayed postal questionnaire can be used in course evaluation. Specifically, the value of the questionnaire as a tool for assessing the impact of short course attendance on general dental practice is examined. METHOD: Questionnaires were distributed to all those attending three courses, ranging in size, in the West Midlands region. As well as reflecting on the course, respondents were asked their views on the usefulness of the questionnaire, the length of time between course attendance and assessment of impact, and types of courses likely to have greatest impact. RESULTS: Respondents thought the questionnaire an appropriate tool for assessing impact on practice, that an appropriate interval of time between the course and the delayed questionnaire is about six weeks, and that courses most likely to impact on practice are those which offer updates on common clinical topics and are hands-on in nature. DISCUSSION: A delayed questionnaire could be a useful mechanism for evaluating the impact on practice of some types of courses. Response rates from those attending large lecture courses might be low. Course evaluation is also limited by resources and time. Criteria for identifying which courses should be subject to such evaluation might include high cost per participant and links with review cycles. CONCLUSION: There is scope for more structured evaluation of continuing dental education, including the assessment of impact on practice. The questionnaire described is a useful component of an evaluation framework.

Vertical shear injuries: is there a relationship between residual displacement and functional outcome?

BACKGROUND: Residual vertical displacement is often cited as being related to poor outcome in patients with pelvic injuries. This study attempts to clarify the relationship between residual vertical displacement and functional outcome. METHODS: From 1982 to 1989, over 500 patients with pelvic ring injuries were treated at two Level I trauma centers. Thirty-three patients with vertical shear (Tile C) fractures and residual displacement (2-52 mm) were evaluated. Outcomes were quantified by using SF-36 Short-Form Health Survey (SF-36) and the Iowa Pelvic Score (IPS). RESULTS: There was no correlation between IPS or SF-36 scales and residual vertical displacement. The IPS correlated (p<0.05) with seven of eight SF-36 categories, excluding mental health. Patients reporting limp and leg length discrepancy also correlated with the IPS and select SF-36. CONCLUSION: Pelvic injuries showed no correlation between functional outcome and residual vertical displacement suggesting other factors. The degree of residual vertical displacement does not affect functional outcome.

A framework for the evaluation of continuing education short courses in dentistry.

The objective of this paper is to propose an evaluation framework for short courses in continuing education for general dental practitioners (GDPs) (so called, Section 63 courses). Existing monitoring and evaluation procedures in the West Midlands deanery were examined and an improved evaluation framework was then devised, piloted and revised. A 5 phase method was used incorporating the examination of existing practice (Phases 1 and 2), development of a new framework (Phase 3), piloting (Phase 4) and revision of the evaluation framework in the light of the pilot. This approach will be implemented in the West Midlands and may be adapted for national use (Phase 5). It was found that existing monitoring and evaluation was inconsistent in prevalence and scope. Those involved in short courses were in favour of a more consistent and visible evaluation, including some assessment of impact-on-practice and cost-effectiveness. In conclusion, meaningful evaluation needs to include four key processes: data gathering; data analysis; dissemination and, action planning (reviewing provision in the light of the data analysis). Thus, this evaluation framework feeds into a quality development cycle designed to ensure high quality and relevant short course provision for general dental practitioners.

1% or less: a community-based nutrition campaign.

OBJECTIVE: The authors evaluated the effectiveness of a community education campaign to encourage a switch from high-fat (whole and 2%) milk to low-fat (1%, 1/2%, and skim) milk as a way to reduce consumption of saturated fat. METHODS: Milk sales data were collected from supermarkets in the intervention and comparison communities for three one-month time periods: at baseline, immediately following the campaign, and six months after the campaign. In addition, trained volunteers conducted pre- and post-intervention telephone surveys. RESULTS: Overall milk sales increased by 16% in the intervention cities following the campaign and remained high at follow-up. Low-fat milk's market share increased from 18% of overall milk sales at baseline to 41% of overall milk sales in the month following the end of the campaign, an increase in market share that was sustained at the six-month follow-up. In the post-intervention telephone survey, 38.2% of those respondents who reported drinking high-fat milk at baseline reported having switched to low-fat milk. CONCLUSION: A focused message communicated through paid advertising, public relations activities, and community-based education programs increased low-fat and overall milk consumption in one community.

The possible-word constraint in the segmentation of continuous speech.

We propose that word recognition in continuous speech is subject to constraints on what may constitute a viable word of the language. This Possible-Word Constraint (PWC) reduces activation of candidate words if their recognition would imply word status for adjacent input which could not be a word--for instance, a single consonant. In two word-spotting experiments, listeners found it much harder to detect apple, for example, in fapple (where [f] alone would be an impossible word), than in vuffapple (where vuff could be a word of English). We demonstrate that the PWC can readily be implemented in a competition-based model of continuous speech recognition, as a constraint on the process of competition between candidate words; where a stretch of speech between a candidate word and a (known or likely) word boundary is not a possible word, activation of the candidate word is reduced. This implementation accurately simulates both the present results and data from a range of earlier studies of speech segmentation.

Pilon fractures treated with an articulated external fixator: a preliminary report.

Nine high-energy pilon fractures with severe soft tissue injuries were treated by a medial external fixator with an articulated ankle-hinge and limited internal fixation (1.7 screws per case). A 100% union rate was achieved; however, there was a 100% complication rate associated with the fixator. Both B3 fractures required a vertical transarticular pin to maintain reduction. Seven C2 fractures suffered calcaneal screw loosening and drainage, necessitating removal of the fixator prior to union. Due to these complications, the articulated ankle hinge could not be utilized. At a minimum of 6 months follow up, eight of nine fractures had acceptable radiographic and early clinical results.

Pelvic ring injuries. A long term functional outcome study.

Eighty patients with pelvic fractures, without hip, spine injuries with neurologic deficits, or traumatic cognitive deficits, 61% treated with external fixators, were reviewed with greater than 5 years of followup. The Short Form-36 General Health Survey, the Iowa pelvic scores, and additional questionnaires concerning return to previous sexual function, occupation, and recreation, and a perception of the worst sequelae of their pelvic trauma were administered. Fractures were classified according to Tile as 25 undisplaced Class A, 31 rotationally displaced Class B, and 24 vertically displaced Class C fractures. Injury severity scores, associated injuries, and mechanisms of injuries were similar across Tile classes. Statistical analysis compared Tile Classes A with B with C and Classes A with B and C. Variations by Tile class among the Short Form-36 survey, Iowa pelvic score, or questionnaire result's were not seen. Approximately 75% of patients returned to their previous sexual function and 80% to their previous occupation. Similarities comparing undisplaced with displaced pelvic fractures question whether reduction of pelvic ring injuries can alter patient long term functional outcomes.

Tibial diaphyseal nonunions after external fixation treated with nonreamed solid core nails.

Twenty-nine patients with tibial diaphyseal fractures had external fixators applied to treat their initial fractures and underwent nonreamed solid core nailing for nonunion (> 22 weeks). Fifteen Alta, 11 Lottes, and 3 Rush nails were used. The original fracture grades were: 1 closed, 1 grade I, 7 grade II, 3 grade IIIA, and 17 grade IIIB. The duration of nonunion was 51 weeks (average: 22 to 173). The average duration of external fixation was 19 weeks (range: 9 to 47). The average interval from fixator removal to nail was 32 weeks (range: 0 to 156). Twenty-eight patients were seen at > 12 months' follow up (average: 35; range: 10 to 58) and completion of treatment. Twenty-seven patients' fractures united at an average of 14 weeks (range: 6 to 40). One patient required a reamed exchange nailing at 39 weeks and united 58 weeks post-exchange nailing. One patient had a persistent asymptomatic nonunion. One patient developed a stress fracture 49 months post nail requiring an exchange nailing. Eleven fractures had a pre-nail deformity of 10 degrees or more; 9 were corrected. Eight patients had pre-nail wound and five had pre-nail pin tract infections. Except for two cases, all of these infections were treated successfully with surgical debridement and/or antibiotics prior to nail insertion. Two patients had their nail inserted through active infections that could not be controlled with an unstable fracture. One patient healed uneventfully in 6 weeks. One required two subsequent debridements. There were no other infections. The authors conclude that nonreamed solid core nailing is an acceptable treatment for tibial diaphyseal nonunions following external fixation.

Selected health-fitness rankings of low-income youth.

Two parameters, tricep skinfold and one-mile walk/run, from the American Alliance for Health, Physical Education, Recreation and Dance health-related fitness test were assessed in 226 low-income children, ages 10 through 14 years. Group means by age and sex were compared with state and national norms. As a whole, on both fitness parameters, this low-income sample fell in the bottom quartile for the state of Maine. The group's national ranking was even lower. Not only are low-income families burdened financially, it appears from this study that the children are also at health risk.

Nonreamed nailing of closed and minor open tibial fractures in patients with blunt polytrauma.

A retrospective comparison of dynamic and static locking mode nonreamed nails in 88 closed, Grades I and II open tibial fractures is presented. Amount of time and number of reoperations required to unite fractures were compared for dynamic (Group 1, n = 31) and static locked (Group 2, n = 13) Winquist I and II fractures, and dynamic (Group 3, n = 14) and static locked (Group 4, n = 30) Winquist III, IV, and segmental fractures. Total reoperations also were compared; Tibias treated with dynamic nails united in an average of 20 weeks, with 3 reoperations; tibias treated with static locked nails united in an average of 30 weeks, with 21 reoperations. Group 1 fractures united in an average of 20 weeks, with 1 reoperation; Group 2 fractures united in an average of 32 weeks, with 4 reoperations. Group 3 fractures united in an average of 20 weeks; Group 4 fractures united in an average of 29 weeks, with 11 reoperations. In the group of tibias treated with dynamic nails, 3 additional operations were done; in the group of tibias treated with static locked nails, 7 additional operations were done. There was 1 infection and 3 deformities. Static locking mode appeared to delay union, especially when Groups 1 and 2 are compared; these fractures can be nailed without locking screws.

Influence of age, sex, balance, and sport participation on development of sidearm striking by children grades K-8.

The purpose of this study was to examine the contributions of age, sex, balance, and sport participation on development of sidearm-striking by children in Grades K through 8. Each of 380 boys and 337 girls (ages 4-14 years), enrolled in a medium-size school system in southeastern Maine, was individually assessed on side-arm-striking and on static and dynamic balance. All subjects completed a survey relative to their participation in school or community-sponsored sports. To assess the independent effects of age, sex, static balance, dynamic balance, and sport participation within each grade, data were subjected to multiple-regression analysis. Development of mature striking was associated with sex; boys performed better at all grades except in Grade 5 where the percentage of girls showing a mature sidearm-striking pattern approximated that of boys.
