Abstract
BACKGROUND Post-TB lung disease (PTLD) can be categorised based on physiological, radiological, and clinical abnormalities, delineating distinct clinical patterns; however, thus far the importance of this is unknown. People with PTLD have a high morbidity and increased mortality, but predictors of long-term outcomes are poorly understood.METHODS We conducted an observational study of PTLD patients attending a tertiary hospital in South Africa between 1 October 2021 and 30 September 2022. Patient demographics, risk factors, symptoms, lung function tests and outcomes were captured.RESULTS A total of 185 patients were included (mean age: 45.2 years, SD ±14.3). Half of patients reported only one previous episode of Mycobacterium tuberculosis infection (n = 94, 50.8%). There was a statistically significant association between TB-associated obstructive lung disease (OLD) and dyspnoea (P = 0.002), chest pain (P = 0.014) and smoking (P = 0.005). There were significant associations between haemoptysis and both cavitation (P = 0.015) and fungal-associated disease (P < 0.001). Six patients (3.2%) died by study end.CONCLUSION PTLD can affect young people even with only one previous episode of TB, and carries a high mortality rate. For the first time, clinical patterns have been shown to have meaningful differences; TB-related OLD is associated with dyspnoea, chest pain and smoking; while haemoptysis is associated with cavitary and fungal-associated disease..

Nature-Based Early Childhood Education and Children's Physical Activity, Sedentary Behavior, Motor Competence, and Other Physical Health Outcomes: A Mixed-Methods Systematic Review. J Phys Act Health 2022; 19:456-472. [PMID: 35537707 PMCID: PMC7613039 DOI: 10.1123/jpah.2021-0760] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 03/04/2022] [Accepted: 04/03/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND The purpose was to synthesize evidence on the association between nature-based Early Childhood Education (ECE) and children's physical activity (PA) and motor competence (MC). METHODS A literature search of 9 databases was concluded in August 2020. Studies were eligible if (1) children were aged 2-7 years old and attending ECE, (2) ECE settings integrated nature, and (3) assessed physical outcomes. Two reviewers independently screened full-text articles and assessed study quality. Synthesis was conducted using effect direction (quantitative), thematic analysis (qualitative), and combined using a results-based convergent synthesis. RESULTS 1370 full-text articles were screened and 39 (31 quantitative and 8 qualitative) studies were eligible; 20 quantitative studies assessed PA and 6 assessed MC. Findings indicated inconsistent associations between nature-based ECE and increased moderate to vigorous PA, and improved speed/agility and object control skills. There were positive associations between nature-based ECE and reduced sedentary time and improved balance. From the qualitative analysis, nature-based ECE affords higher intensity PA and risky play, which could improve some MC domains. The quality of 28/31 studies was weak. CONCLUSIONS More controlled experimental designs that describe the dose and quality of nature are needed to better inform the effectiveness of nature-based ECE on PA and MC.

Synovial fluid leukocyte cell count before versus after administration of antibiotics in patients with septic arthritis of a native joint. J Orthop Sci 2020; 25:907-910. [PMID: 31917066 DOI: 10.1016/j.jos.2019.11.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 10/16/2019] [Accepted: 11/24/2019] [Indexed: 02/09/2023]
Abstract
BACKGROUND Antibiotics have been shown to affect the accuracy of cultures; so antibiotics are held prior to obtaining cultures intra-operatively. No study has evaluated the effects of antibiotics on synovial fluid leukocyte cell count. The purpose of the current study is to compare the leukocyte cell count of native joints with septic arthritis when antibiotics have been given before aspiration and when no antibiotics have been given prior to aspiration. METHODS This study was performed at a community hospital and a level 1 urban trauma hospital after IRB approval from both institutions from July 2007 to July 2017. Inclusion criteria comprised of a diagnosis of septic arthritis with positive cultures and a recorded arthrocentesis with cell count performed. Patients with septic arthritis were identified using ICD-9 codes 711.00-711.99 and ICD-10 codes M00 - M02. A retrospective chart review was performed and data was collected. Patients were placed into one of two groups. Group 1 received no antibiotics for two weeks prior to arthrocentesis, group 2 received antibiotics within 24 h prior to arthrocentesis. Demographic information, cell count number and differential, and blood lab values were collected. Timing data was also collected on timing of admission, antibiotics, joint irrigation, and discharge from the inpatient setting. RESULTS There were 81 patients meeting final inclusion criteria. The average cell count for the group which received antibiotics (n = 30) was 40,408 ± 29,433 while the average cell count for the group receiving no antibiotics (n = 51) was 93,824 ± 73,875 (p < .0001). The average length of stay was not significantly different between the antibiotic group versus no antibiotic group (14.0 days vs 12.1 days p = .4). The time from admission to arthrocentesis and admission to washout was longer for the antibiotic group versus no antibiotic group (p = .004 and p = .002, respectively). CONCLUSION When antibiotics are given prior to arthrocentesis of a septic joint, there is an associated lower synovial fluid leukocyte count compared to when no antibiotics are given prior. LEVEL OF EVIDENCE Level III.

Evaluation of a phased pneumococcal conjugate vaccine introduction in Mongolia using enhanced pneumonia surveillance and community carriage surveys: a study protocol for a prospective observational study and lessons learned. BMC Public Health 2019; 19:333. [PMID: 30898094 PMCID: PMC6429832 DOI: 10.1186/s12889-019-6639-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2018] [Accepted: 03/08/2019] [Indexed: 11/17/2022] Open
Abstract
Background Streptococcus pneumoniae causes substantial morbidity and mortality among children. The introduction of pneumococcal conjugate vaccines (PCV) has the potential to dramatically reduce disease burden. As with any vaccine, it is important to evaluate PCV impact, to help guide decision-making and resource-allocation. Measuring PCV impact can be complex, particularly to measure impact on one of the most common and significant diseases caused by the pneumococcus, namely pneumonia. Here we outline the protocol developed to evaluate the impact of 13-valent PCV (PCV13) on childhood pneumonia in Mongolia, and a number of lessons learned in implementing the evaluation that may be helpful to other countries seeking to undertake pneumonia surveillance. Methods From 2016 PCV13 was introduced in a phased manner into the routine immunisation programme with some catch-up by the Government of Mongolia. We designed an evaluation to measure vaccine impact in children aged 2–59 months with hospitalised radiological pneumonia as a primary outcome, with secondary objectives to measure impact on clinically-defined pneumonia, nasopharyngeal carriage of S. pneumoniae among pneumonia patients and in the community, and severe respiratory infection associated with RSV and/or influenza. We enhanced an existing hospital-based pneumonia surveillance system by incorporating additional study components (nasopharyngeal swabbing using standard methods, C-reactive protein, risk factor assessment) and strengthening clinical practices, such as radiology as well as monitoring and training. We conducted cross-sectional community carriage surveys to provide data on impact on carriage among healthy children. Discussion Establishing a robust surveillance system is an important component of monitoring the impact of PCV within a country. The enhanced surveillance system in Mongolia will facilitate assessment of PCV13 impact on pneumonia, with radiological confirmed disease as the primary outcome. Key lessons arising from this evaluation have included the importance of establishing a core group of in-country staff to be responsible for surveillance activities and to work closely with this team; to be aware of external factors that could potentially influence disease burden estimates; to be flexible in data collection processes to respond to changing circumstances and lastly to ensure a consistent application of the pneumonia surveillance case definition throughout the study period.

Abstract
OBJECTIVES To review empirical evaluations of individual-level interventions intended to improve mental health or well-being for vulnerable adolescents. STUDY DESIGN This is a systematic mapping review. METHODS Thirteen databases covering academic and gray literature were searched for published reviews and randomised controlled trials, and gray literature (2005-2016) and the results quality-assessed to prioritise best available evidence. We aimed to identify well-conducted systematic reviews and trials that evaluated individual-level interventions, for mental health/well-being outcomes, where the population was adolescents aged 10-24 years in any of 12 vulnerable groups at high risk of poor health outcomes (e.g. homeless, offenders, 'looked after', carers). RESULTS Thirty systematic reviews and 16 additional trials were identified. There was insufficient evidence to identify promising individual-level interventions that improve the mental health/well-being of any of the vulnerable groups. CONCLUSIONS Despite Western policy to promote health and well-being among vulnerable young people, the dearth of evidence suggests a lack of interest in evaluating interventions targeting these groups in respect of their mental health/well-being outcomes.

Abstract
Satisfactory experience with single-layer colorectal anastomosis during 1969–74 led to an analysis of the results of single-layer large bowel anastomosis during the subsequent years 1975–79. This technique has continued to be associated with a low incidence of anastomotic failure, but anastomotic integrity also depends on rigorous attitudes to bowel preparation, to bacterial contamination and to the avoidance of anastomosis when the risk of anastomotic failure is high.

Abstract
Background Pediatric anaphylaxis is commonly misdiagnosed in the Emergency Department (ED). We aimed to determine the impact of inaccurate diagnosis on the management and follow-up of pediatric anaphylaxis presenting to the ED. Methods Retrospective chart review of ED management of children aged 0–18 years with allergic presentations to three EDs in Melbourne, Australia in 2014. Cases were included if an ED diagnosis of anaphylaxis was recorded, or the presentation met international consensus criteria for anaphylaxis. Results Of the 60,143 pediatric ED presentations during the study period, 1551 allergy-related presentations were identified and reviewed. 187 met consensus criteria for anaphylaxis, and another 24 were diagnosed with anaphylaxis without meeting criteria. Of the 211 presentations, 105 cases were given an ED diagnosis of anaphylaxis and 106 cases were given an alternative diagnosis in ED. Those diagnosed with anaphylaxis were more likely to receive epinephrine [85.7% vs 31.1% (OR = 13.27, 95% CI: 6.09–26.3)], to be observed for the recommended four hours [56.2% vs 29.2% (OR = 3.10, 95% CI 1.76–5.48, p < 0.001)], to have an epinephrine autoinjector available on discharge [81.9% vs 35.8% (OR = 4.12, 95% CI 2.07–8.22, p < 0.001)] and to be referred to an allergist [35.2% vs 16.0% (OR = 2.85, 95% CI 1.48–5.49, p < 0.01)]. Provision of anaphylaxis action plans and allergen avoidance advice was poorly documented for all patients. Conclusion Accurate diagnosis of anaphylaxis in ED has a significant impact on observation times, prescription of epinephrine autoinjectors and referral to an allergist. These factors are key to reducing mortality and the significant morbidity that results from childhood anaphylaxis.

Abstract
Approximately one in four incarcerated male young offenders in the UK is an actual or expectant father. This paper reviews evidence on the effectiveness of parenting interventions for male young offenders. We conducted systematic searches across 20 databases and consulted experts. Twelve relevant evaluations were identified: 10 from the UK, of programmes for incarcerated young offenders, and two from the US, of programmes for young parolees. None used experimental methods or included a comparison group. They suggest that participants like the courses, find them useful, and the interventions may improve knowledge about, and attitudes to, parenting. Future interventions should incorporate elements of promising parenting interventions with young fathers in the community, for example, and/or with older incarcerated parents. Young offender fathers have specific developmental, rehabilitative, and contextual needs. Future evaluations should collect longer-term behavioural parent and child outcome data and should use comparison groups and, ideally, randomization.

Abstract
AIMS To comprehensively characterize large artery biomechanical properties and examine their relationship to cardiac function in patients with Type 2 diabetes mellitus (DM). METHODS Fifty-five individuals with Type 2 DM were compared with 66 age- and sex-matched healthy control subjects. Arterial biomechanical properties were assessed by systemic arterial compliance (SAC; two-element Windkessel model), carotid-femoral pulse wave velocity (PWVc-f), femoral-dorsalis pedis pulse wave velocity (PWVf-d) and carotid augmentation index. Cardiac structure and function were assessed by echocardiography. RESULTS Individuals with Type 2 DM had lower SAC and higher PWVc-f when compared with the healthy population. The PWVc-f was significantly lower than the PWVf-d in control individuals, but this difference was not evident in individuals with Type 2 DM due to higher PWVc-f. Augmentation index was similar in both groups, but the time to the first systolic inflection (time to reflection) was shorter in the individuals with Type 2 DM. The individuals with Type 2 DM had a greater prevalence of diastolic abnormalities when compared with the control group. Arterial stiffness indices, including SAC and pulse pressure, correlated with left ventricular filling pressure (defined as peak velocity during early diastolic filling divided by the velocity of movement of the mitral valve annulus in early diastole; r = -0.33 and 0.36 respectively. CONCLUSIONS Patients with Type 2 DM on standard medication showed preferential stiffening of the large central arteries. However, carotid augmentation index was not different between the two groups and is therefore not a reliable indicator of large artery stiffening in this patient group. Diastolic dysfunction, present in a significant proportion of this population with Type 2 DM, was closely associated with arterial stiffening, suggesting a common aetiology.

Abstract
BACKGROUND Second-hand tobacco smoke is a serious health hazard. We tested the fidelity and feasibility of the Smoke-Free Homes (SFH) intervention and looked for preliminary evidence of its effectiveness in imposing smoking restrictions in homes in Pakistan. METHODS SFH was piloted and adapted for Pakistan. The adapted SFH intervention was then delivered to primary schoolchildren, community leaders and health professionals in a semi-rural Union Council. We carried out a survey before and after the intervention to assess adult smoking behaviour and restrictions at homes. We also carried out focus group discussions with stakeholders to determine the appropriateness and acceptability of the intervention. RESULTS We found the adapted SFH intervention feasible and appropriate in a typical semi-rural setting in Pakistan. The proportion of smoke-free homes increased from 43% (95%CI 37.4-48.2) to 85% (95%CI 80.9-89.2) after the intervention. The number of households with at least one smoker decreased from 57.5% (95%CI 52.1-62.9) to 38.4% (95%CI 32.7-44.1). There was a reduction in self-reported adult smoking prevalence from 44% (95%CI 39-48) to 28% (95%CI 24-33) in males. CONCLUSION SFH has the potential to influence adult smoking behaviour in households. This approach needs to be further evaluated to establish its effectiveness and cost-effectiveness and to ascertain its long-term sustainability.

Abstract
Abstract
Introduction: NICE recommends that the majority of women undergoing mastectomy should be offered immediate breast reconstruction with its potential benefits to improve health related quality of life (HRQL). A systematic review shows poor and conflicting evidence with a lack of 'hard' data to best inform both clinicians and their patients. Our aim was to evaluate the effects of implant-assisted LD (LDI) versus autologous LD (ALD) breast reconstruction on HRQL over 36 months. Recently, with the exception of the USA Breast-Q module there is a lack of a validated Breast reconstruction questionnaire.Methods: An MREC approved prospective longitudinal cohort study involving 6 centres commenced in early 2007. Serial patient reported outcome measures using the EORTC C30 (global QoL, physical functioning, fatigue, pain), BR-23 (breast and arm symptoms), 10 item Body Image Scale (BIS) and HADS, were completed pre-operatively and at 3, 6, 12, 24 and 36 months after surgery. Overall cosmetic satisfaction of the breast reconstruction was measured by a study-specific question on a 5 point Likert scale. Generalised estimating equations were used to assess change over time and differences between treatment groups.The Spearman's rank correlation coefficient was used to assess associations between patient reported cosmetic satisfaction with BIS and breast symptoms.Results: 118 patients (65 – ALD, 53 – LDI) were recruited to the study with a mean age of 50 years (range 22-70). Compliance with questionnaires at all time points was between 85-90%. There were no significant differences in HRQL domains between LDI and ALD, except a tendency for worse pain with ALD (p=0.06). Significant improvements over time were seen for overall HRQL (p<0.001), fatigue (p<0.001), breast symptoms (p=0.04), arm symptoms (p=0.001), as well as anxiety (p=0.017) and depression (p<0.001). Preliminary data shows that overall cosmetic satisfaction was significantly correlated with better body image and fewer breast symptoms. The study is ongoing in terms of 24 and 36 months follow-up and the evaluation of RT.Conclusion: There is an important need for cumulative clinical evidence in this field on which to base patient informed consent and clinical recommendations. Further analyses will assess whether there is an independent effect of RT on HRQL. A validated EORTC breast reconstruction module is in development.

Abstract
Many urban policies aim to improve areas and address socioeconomic deprivation. The resulting investment is often delivered through area-based programmes which incorporate initiatives to improve the physical, social and economic environment. Hypotheses that these investments can contribute to wider public health strategies are based on epidemiological data and used to support the concept of healthy urban policy. However, there is little evidence on their ability to generate positive impacts on socioeconomic or health outcomes. The lack of validating evidence on actual impacts raises two important questions: (1) Is area-based investment an effective strategy to tackle socioeconomic deprivation? (2) What is the prospect for new and improved evaluations to provide stronger evidence? Both the programmes of area investment and their accompanying evaluations have been criticised for being overly ambitious in what can be achieved by the investment and what can be measured by an evaluation. Area-based approaches to tackling deprivation have their advantages but a mix of area and individual-level targeting is likely to be needed. While there is scope to improve the utility of evaluation data there are also inevitable constraints on assessing and attributing impacts from urban investment. The inherent limitations to an area-based approach and the ongoing constraints on impact evaluation will inevitably temper expectations of what healthy urban policy can achieve. However, lack of evidence is not grounds to abandon the concept of healthy urban policy; adoption of more realistic expectations together with improved evaluation data may help to increase its credibility.

Abstract
BACKGROUND Less than half of studies presented at conferences remain unpublished two years later, and these studies differ systematically from those that are published. In particular, the unpublished studies are less likely to report statistically significant findings, and this introduces publication bias. This has been well documented for quantitative studies, but has never been explored in relation to qualitative research. METHODS We reviewed the abstracts of qualitative research presented at the 1998 (n = 110) and 1999 (n = 114) British Sociological Association (BSA) Medical Sociology meetings, and attempted to locate those studies in databases or by contacting authors. We also appraised the quality of reporting in each abstract. RESULTS We found an overall publication rate for these qualitative studies of 44.2%. This is nearly identical to the publication rate for quantitative research. The quality of reporting of study methods and findings in the abstract was positively related to the likelihood of publication. CONCLUSION Qualitative research is as likely to remain unpublished as quantitative research. Moreover, non-publication appears to be related to the quality of reporting of methodological information in the original abstract, perhaps because this is a proxy for a study with clear objectives and clear findings. This suggests a mechanism by which "qualitative publication bias" might work: qualitative studies that do not show clear, or striking, or easily described findings may simply disappear from view. One implication of this is that, as with quantitative research, systematic reviews of qualitative studies may be biased if they rely only on published papers.

Abstract
Abstract
Background
Latissimus dorsi (LD) flap breast reconstruction is associated with a high incidence of donor site seromas, despite the use of surgical drains. The aim of this study was to evaluate the use of donor site quilting sutures, as well as drains, on the incidence, volume and frequency of seroma aspiration.
Methods
The trial randomized 108 women undergoing LD breast reconstruction to quilting procedures (54) or control group (52) for intention-to-treat analysis; two were excluded. Outcome measures were the incidence and volume of postoperative seroma. Secondary outcome measures included postoperative back pain, analgesic consumption, shoulder movement and duration of hospital stay.
Results
Quilting significantly reduced the overall incidence of seroma from 46 of 48 (96 per cent) to 43 of 52 (83 per cent) (P = 0·036), including the 38 women who had extended LD flap (with or without implants). There were further significant reductions in seroma volume (P = 0·004), frequency of aspiration (P = 0·001) and overall seroma volumes, including surgical drainage and symptomatic seromas (P = 0·013). Subset analyses for LD–implant (60 women) and extended LD (with or without implant) showed similar significance. Quilting did not affect back pain or compromise shoulder mobility.
Conclusion
Quilting significantly reduced overall seroma volumes after LD breast reconstruction including extended LD, and is recommended in combination with surgical drains.

Abstract
OBJECTIVES To obtain comprehensive information about venous ulcer services throughout the United Kingdom (UK). DESIGN Questionnaire based survey. MATERIALS Questionnaire. METHODS Letters about venous ulcer services were sent to consultant vascular surgeons in all areas of the UK (total 181). Questionnaires were then directed to the appropriate clinician in each area. RESULTS Responses were received from 177 (98%) areas. Fifteen (8%) had no dedicated service. Completed questionnaires were returned for 112 (63%) areas. Fifty-six (54%) services were managed by acute hospitals, 29 (28%) by primary care (community) and 19 (18%) jointly. Doctors supervised services in 65 (64%) (vascular surgeons 49, dermatologists 12, both 4) and nurses in 31 (33%). New referrals per week were 1-50 based on audit (33%) or estimates (67%). Sixty-three (58%) services had no database. Written guidelines existed for 76% services (90% nurse-supervised and 64% doctor-supervised services--p<0.02). CONCLUSIONS Dedicated venous ulcer services have been shown to improve healing rates and quality of life. Although now present in most areas of the UK, their organisation varies considerably and many are not based in the community, near patients homes. This survey provides a benchmark for comparison with venous ulcer services in other countries.

Abstract
BACKGROUND The changes to out of hours care provided by General Practitioners have led to wide variation in the types and costs of out of hours care across the country. AIM To examine the costs of different models of service delivery for GP out of hours organisations. METHODS This was a prospective cross-sectional survey of eight GP out of hours organisations and samples of their patients. A deputising service, rotas, and various types of GP co-operative across Scotland were surveyed. Information on the quantities of resources used by each organisation was combined with unit costs. Costs incurred by patients and other NHS costs subsequent to the out of hours contact were also calculated. RESULTS Annual costs incurred by the GP out of hours organisation per 1,000 population ranged from pounds sterling 2,916 to pounds sterling 12,120. There was no relationship between costs and type and size of organisation. There was a three-fold variation in total costs per out of hours contact (pounds sterling 15 to pounds sterling 51). Costs per phone contact were lowest (pounds sterling 6 to pounds sterling 11), followed by cost per centre contact (pounds sterling 10 to pounds sterling 16) and cost per home contact (pounds sterling 21 to pounds sterling 60). Total costs per episode ranged from pounds sterling 78 to pounds sterling 136 for centre contacts, from pounds sterling 130 to pounds sterling 303 for home contacts, and from pounds sterling 70 to pounds sterling 553 for telephone contacts. Home contacts had the highest average cost per episode (pounds sterling 212), followed by telephone contacts (pounds sterling 117) and centre contacts (pounds sterling 85). CONCLUSIONS There are wide variations in the costs of operating GP out of hours services, It is likely that the context in which organisations were set up and local geography infuence variations in costs, as well as the level of GP cover.

Abstract
STUDY OBJECTIVE To assess the health impacts of local public swimming pool and leisure provision. DESIGN Retrospective qualitative study using focus groups. Reports from two areas with contrasting experience of provision of a public swimming pool (opening and closure) were compared within the context of general reports about health and neighbourhood. SETTING Two deprived neighbourhoods in south Glasgow. PARTICIPANTS Local adult residents of mixed ages, accessed through local community groups. MAIN RESULTS In both areas the swimming pool was reported as an important amenity that was linked to health and wellbeing. However, few residents reported regular use of the pool for physical activity. Use of the pool facility for social contact was directly linked to reports of relief of stress and isolation, and improved mental health. Pool closure was one in a series of amenity closures and area decline and was used to represent other area changes. Health impacts were strongly linked to the pool closure. The pool opening was associated with local area regeneration, similar but less prominent links between swimming pool provision and health were reported. Health benefits of social contact were diffuse and linked to other local amenities as well as the new pool facility. CONCLUSIONS Although theoretically linked to increased physical activity, the health benefits conveyed by the swimming pool may be more closely linked to the facilitation of social contact, and a supervised facility for young children. The use of qualitative work to investigate area based change provides rich contextual data to strengthen and explain the reported health impacts.

Abstract
STUDY OBJECTIVE To review systematic review literature that describes the effectiveness of transport interventions in improving population health. METHODS Systematic review methodology was used to evaluate published and unpublished systematic reviews in any language that described the measured health effects of any mode of transport intervention. MAIN RESULTS 28 systematic reviews were identified. The highest quality reviews indicate that the most effective transport interventions to improve health are health promotion campaigns (to prevent childhood injuries, to increase bicycle and motorcycle helmet use, and to promote children's car seat and seatbelt use), traffic calming, and specific legislation against drink driving. Driver improvement and education courses are associated with increases in crash involvement and violations. CONCLUSIONS Systematic reviews are able to provide evidence about effective ways of improving health through transport related interventions and also identify well intentioned but harmful interventions. Valuable additional information may exist in primary studies and systematic reviews have a role in evaluating and synthesising their findings.

Abstract
BACKGROUND Health impact assessment (HIA) has been widely recommended for future social policies and investment, such as housing improvement. However, concerns have been raised about the utility and predictive value of an HIA. Use of existing research data would add more weight to forecasts by an HIA. METHODS, RESULTS, and CONCLUSIONS A recent systematic review of housing intervention studies found a lack of research. The authors recommended that a broader evidence base would be needed to support HIA. In response to consultation with policymakers and HIA practitioners this paper presents a way in which research can be used to inform HIA. Based on the systematic review, the authors have developed a table of synthesised findings indicating the expected health effects of specific housing improvements. The authors also reviewed observational data of housing associated health risks to highlight the key impacts to consider when doing a housing HIA. The findings are presented and the authors discuss how they should be used to inform evidence based housing HIA. In addition to considering the existing research, HIA must consider the local relevance of research. Consultation with local stakeholders also needs to be incorporated to the final assessment. The lack of data and the difficulties in gathering and reviewing data mean that not all HIAs will be able to be informed by research evidence. Well conducted prospective validation of HIAs would contribute to the development of healthy housing investment by informing future housing HIA.

Abstract
A two-and-a-half-year-old Friesian cow and a five-year-old Charolais cow developed severe respiratory distress and palpable swellings to the left of the larynx as a result of a dissecting aneurysm of the common carotid artery. Neither cow responded to medical treatment. The underlying pathogenesis of the condition was uncertain, but direct trauma to the carotid artery was a possible contributory factor. Aneurysms of the common carotid artery should be considered when swelling occurs in the region of the larynx or when respiratory distress is due to laryngeal compression.

Abstract
OBJECTIVE To review the evidence on the effects of interventions to improve housing on health. DESIGN Systematic review of experimental and non-experimental housing intervention studies that measured quantitative health outcomes. DATA SOURCES Studies dating from 1887, in any language or format, identified from clinical, social science, and grey literature databases, personal collections, expert consultation, and reference lists. MAIN OUTCOME MEASURES Socioeconomic change and health, illness, and social measures. RESULTS 18 completed primary intervention studies were identified. 11 studies were prospective, of which six had control groups. Three of the seven retrospective studies used a control group. The interventions included rehousing, refurbishment, and energy efficiency measures. Many studies showed health gains after the intervention, but the small study populations and lack of controlling for confounders limit the generalisability of these findings. CONCLUSIONS The lack of evidence linking housing and health may be attributable to pragmatic difficulties with housing studies as well as the political climate in the United Kingdom. A holistic approach is needed that recognises the multifactorial and complex nature of poor housing and deprivation. Large scale studies that investigate the wider social context of housing interventions are required.

Abstract
Carotid duplex ultrasound (CDUS) is a non-invasive technique used to assess the severity of carotid artery stenosis. It has been shown to have good correlation with digital subtraction angiography (DSA) but has been criticised for its variability. One source of this is the variation in results between studies responsible for re-validating velocity criteria to match the established treatment thresholds of internal carotid artery (ICA) stenosis. The aim of this study was to develop velocity criteria and determine the presence of inter-sonographer variation of CDUS when grading ICA stenosis in our department. Five sonographers measured the degree of ICA stenosis with CDUS in 33 patients who also underwent DSA. Receiver operator characteristic curve analysis was used to develop optimal velocity criteria for the 50%, 70% and 90% ICA stenosis thresholds as a group and for each individual sonographer. A peak systolic velocity ratio of > or = 3.25 was shown to have the highest accuracy (91.5%) for predicting a 70% stenosis. A moderate value of kappa (0.53 +/- 0.027) was calculated if the optimum velocity criterion was employed for each sonographer. There was no significant variation between the ability of sonographers to grade ICA stenosis (P > 0.05) and an excellent ICC of 0.911 was calculated. This study provides evidence to suggest that CDUS in our department is not an operator-dependant test for the investigation of ICA stenosis.

Abstract
Endothelial dysfunction, an early event in atherogenesis, has been demonstrated in young asymptomatic subjects with a strong family history of premature coronary artery disease (CAD). In these subjects, preventive measures involving risk factor modification are not appropriate, and strategies employing novel antiatherogenic agents, such as the dihydropyridine calcium channel blocker, amlodipine, may be useful. Ninety-one subjects (mean age, 28.6 years; range, 18-40) with a strong family history of premature CAD and no other identified vascular risk factors were randomised to either 5 mg amlodipine (49 subjects) or placebo (42 subjects). Brachial artery flow mediated dilatation (FMD) (endothelium-dependent response) and response to glyceryltrinitrate (GTN) (direct smooth muscle dilator) were assessed non-invasively at baseline, and after 12 and 24 weeks using high-resolution vascular ultrasound. In those treated with amlodipine, mean FMD increased from 2.32+/-2.23% at baseline to 3.52+/-3.1% at 24 weeks (P<0.005). However, FMD also increased in the placebo group from 1.64+/-2.12 to 3.37+/-2.68% (P<0.002), and the difference between the FMD response in the amlodipine and placebo groups was not significant. Dilatation to GTN did not change in either group. Therefore, impaired endothelial function improved in family history subjects taking both amlodipine and placebo, but there is no difference between the groups.
