Impact of a 6-12-h delay between ileocolic intussusception diagnostic US and fluoroscopic reduction on patients' outcomes.

BACKGROUND: Image-guided reduction of intussusception is considered a radiologic urgency requiring 24-h radiologist and technologist availability. OBJECTIVE: To assess whether a delay of 6-12 h between US diagnosis and fluoroscopic reduction of ileocolic intussusception affects the success frequency of fluoroscopic reduction. MATERIALS AND METHODS: Retrospective review of 0-5-year-olds undergoing fluoroscopic reduction for ileocolic intussusception from 2013 to 2023. Exclusions were small bowel intussusception, self-reduced intussusception, first fluoroscopic reduction attempt>12 h after US, prior bowel surgery, inpatient status, and patient transferred for recurrent intussusception. Data collected included demographics, symptoms, air/contrast enema selection, radiation dose, reduction failure, 48-h recurrence, surgery, length of stay, and complications. Comparisons between<6-h and 6-12-h delays after ultrasound diagnosis were made using chi-square, Fisher's exact test, and Mann-Whitney U tests (P< 0.05 considered significant). RESULTS: Of 438 included patients, 387 (88.4%) were reduced in <6 h (median age 1.4 years) and 51 (11.7%) were reduced between 6 and 12 h (median age 2.05 years), with median reduction times of 1:42 and 7:07 h, respectively. There were no significant differences between the groups for reduction success (<6 h 87.3% vs. 6-12 h 94.1%; P-value = 0.16), need for surgery (<6 h 11.1% vs. 6-12 h 3.9%; P-value=0.112), recurrence of intussusception within 48 h after reduction (<6 h 9.3% vs. 6-12 h 15.7%; P-value=0.154), or length of hospitalization (<6 h 21:07 h vs. 6-12 h 20:03 h; P-value=0.662). CONCLUSION: A delay of 6-12 h between diagnosis and fluoroscopic reduction of ileocolic intussusception is not associated with reduced fluoroscopic reduction success, need for surgical intervention after attempted reduction, recurrence of intussusception following successful reduction, or hospitalization duration after reduction.

Quality and Diagnosis on the Lateral View of Pediatric Upper Gastro-Intestinal Series.

BACKGROUND: The standard imaging technique for the diagnosis of intestinal malrotation remains the upper gastro-intestinal series (UGIS). The lateral view is promoted as important for making a diagnosis. For this, the lateral view should be of adequate quality, and radiologists must know the normal appearance as well as the appearance of duodenal variants, as misdiagnosis may lead to unnecessary surgery. OBJECTIVE: We aimed to evaluate the quality, findings including the prevalence of the "descending staircase" configuration and its correspondence to a diagnosis of duodenum redundum. MATERIALS AND METHODS: This was a retrospective study and was conducted in a large tertiary children's hospital in the United States. A retrospective review of UGI fluoroscopy exams in children aged ≤ 18 years between January and December 2018 was performed by a pediatric radiologist. First, the lateral view images/cine-loops were assessed independently, followed by the anteroposterior (AP) view. The studies which were designated to have an adequate lateral view were evaluated for configuration of the duodenum and recorded as: normal, abnormal, or normal variant. Also, the presence of a descending staircase configuration was correlated with an AP view for a diagnosis of duodenum redundum. RESULTS: A total of 26 children (26%) (males:16; females:10) with age range 0 to 16 years had adequate lateral views during UGI exams for inclusion. Of the 26, 18 (69%) were reported as normal, 7 (27%) were reported as having a descending staircase and 1 (4%) was reported as abnormal. The AP view demonstrated 2 abnormal studies (1 malrotation and 1 non-rotation), 6 duodenum redundum and 18 normal exams. The one abnormal lateral duodenum was confirmed as a non-rotation on AP view; the second patient with an abnormal AP view had a normal appearance on the lateral view. CONCLUSIONS: A total of 26% of UGI studies had adequate lateral views for interpretation. Of these, nearly a quarter (23%) demonstrated the descending stair-case sign corresponding to a diagnosis of duodenum redundum on the AP view. If the lateral view had been used alone, there would have been a missed diagnosis in one patient.

Imaging Stewardship: Triage for Neuroradiology MR During Limited-Resource Hours.

OBJECTIVES: To decrease call burden on pediatric neuroradiologists, we developed guidelines for appropriate use of MR overnight. These guidelines were implemented using triage by in-house generalist pediatric radiologists. Process measures and balancing measures were assessed during implementation. METHODS: For this improvement project, interdepartmental consensus guidelines were developed using exploratory mixed-methods design. Implementation of triage used plan-do-study-act cycles. Process measures included reduction in the number of telephone calls, frequency of calls, triage decisions, and number and type of examinations ordered. Balancing measures included burden of time and effort to the generalist radiologists. Differences in examination orders between implementation intervals was assessed using Kruskal-Wallis, with significance at P < .05. RESULTS: Consensus defined MR requests as "do," "defer," or "divert" (to CT). Guidelines decreased neuroradiologist calls 74% while adding minimal burden to the generalist radiologists. Most nights had zero or one triage request and the most common triage decision was "do," and the most common examination was routine brain MR. Number of MR ordered and completed overnight did not significantly change with triage. DISCUSSION: Multidisciplinary consensus for use of pediatric neurological MR during limited resource hours overnight is an example of imaging stewardship that decreased the burden of calls and burnout for neuroradiologists while maintaining a comparable level of service to the ordering clinicians.

Evaluation of the Cerebrospinal Fluid Flow Dynamics with Microvascular Imaging Ultrasound in Infants.

PURPOSE: Microvascular imaging ultrasound (MVI) can detect slow blood flow in small-caliber cerebral vessels. This technology may help assess flow in other intracranial structures, such as the ventricular system. In this study, we describe the use of MVI for characterizing intraventricular cerebrospinal fluid (CSF) flow dynamics in infants. MATERIALS AND METHODS: We included infants with brain ultrasound that had MVI B-Flow cine clips in the sagittal plane. Two blinded reviewers examined the images, dictated a diagnostic impression, and identified the third ventricle, cerebral aqueduct, fourth ventricle, and CSF flow direction. A third reviewer evaluated the discrepancies. We evaluated the association of visualization of CSF flow as detectable with MVI, with the diagnostic impressions. We also assessed the inter-rater reliability (IRR) for detecting CSF flow. RESULTS: We evaluated 101 infants, mean age 40 ± 53 days. Based on brain MVI B-Flow, a total of 49 patients had normal brain US scans, 40 had hydrocephalus, 26 had intraventricular hemorrhage (IVH), and 14 had hydrocephalus+IVH. Using spatially moving MVI signal in the third ventricle, cerebral aqueduct, and fourth ventricle as the criteria for CSF flow, CSF flow was identified in 10.9% (n = 11), 15.8% (n = 16), and 16.8% (n = 17) of cases, respectively. Flow direction was detected in 19.8% (n = 20) of cases; 70% (n = 14) was caudocranial, 15% (n = 3) was craniocaudal, and 15% (n = 3) bidirectional, with IRR = 0.662, p < 0.001. Visualization of CSF flow was significantly associated with the presence of IVH alone (OR 9.7 [3.3-29.0], p < 0.001) and IVH+hydrocephalus (OR 12.4 [3.5-440], p < 0.001), but not with hydrocephalus alone (p = 0.116). CONCLUSION: This study demonstrates that MVI can detect CSF flow dynamics in infants with a history of post-hemorrhagic hydrocephalus with a high IRR.

Utility of Cerebral Microvascular Imaging in Infants Undergoing ECMO.

PURPOSE: Infants who require extracorporeal membrane oxygenation (ECMO) therapy have an increased risk of neurological complications and mortality. Microvascular imaging (MVI) is an advanced Doppler technique that allows high-resolution visualization of microvasculature in the brain. We describe the feasibility and utility of MVI for the evaluation of cerebral microvascular perfusion in patients undergoing ECMO. METHODS: We retrospectively analyzed brain MVI scans of neonates undergoing ECMO. Two pediatric radiologists qualitatively assessed MVI scans to determine the presence or absence of tortuosity, symmetry, heterogeneity, engorgement, and hypoperfusion of the basal ganglia-thalamus (BGT) region, as well as the presence or absence of white matter vascular engorgement and increased peri-gyral flow in the cortex. We tested the association between the presence of the aforementioned brain MVI features and clinical outcomes. RESULTS: We included 30 patients, 14 of which were male (46.7%). The time of ECMO duration was 11.8 ± 6.9 days. The most prevalent microvascular finding in BGT was lenticulostriate vessel tortuosity (26/30, 86.7%), and the most common microvascular finding in the cortex was increased peri-gyral flow (10/24, 41.7%). Cortical white matter vascular engorgement was significantly associated with the presence of any poor outcome as defined by death, seizure, and/or cerebrovascular events on magnetic resonance imaging (p = 0.03). CONCLUSION: MVI is a feasible modality to evaluate cerebral perfusion in infants undergoing ECMO. Additionally, evidence of white matter vascular engorgement after ECMO cannulation could serve as a predictor of poor outcomes in this population.

Frequency of duodenal anatomical variants in neonatal and pediatric upper gastrointestinal tract series (UGI) and the influence of exam quality on diagnostic reporting of these.

AIM: To determine frequency of duodenal anatomical variants on clinically indicated pediatric UGI examinations and determine the influence of these variants and exam quality on the reliability of diagnosis. MATERIALS AND METHODS: Two-pediatric radiologists retrospectively reviewed 100-UGI exams performed on children ≤18-years. Exams were considered diagnostic if the duodenojejunal (DJ) flexure was identified. For diagnostic exams, readers categorized the duodenal location and shape as: normal, normal variant, or abnormal. Exam quality was assessed according to duodenal visualization, number of boluses required, and patient positioning. RESULTS: Reader 1: 90/100 exams diagnostic -77% normal duodenum, 20% normal variant, and 3% abnormal. Reader 2: 97/100 exams diagnostic - 88% normal, 8% normal variant, and 4% abnormal. Original reports: 99/100 exams diagnostic - 92% normal, 3% normal variant, and 5% abnormal. 42% of exams were "high-quality" and 58% were "low-quality". The number of abnormal was the same between readers in "high-quality" studies. In "low-quality" studies reader 1 and the original read diagnosed 1 further case as non-rotation which was diagnosed as a normal variant by reader 2. Two further cases were reported as non-rotation by the original reader. Inter-rater reliability was significantly higher among each pair of raters in "high quality" exams (κ 0.3; p ≤ 0.05) compared to "low quality" exams (k < 0.1 - p > 0.05). CONCLUSION: Duodenal variants were diagnosed in 8-20% of UGI. Compromised exam quality contributes to poor interrater reliability and may result in diagnostic errors of normal variant duodenums, posing a risk for unnecessary intervention and/or delayed treatment.

The role of ultrasound in necrotizing enterocolitis.

Ultrasound has proved to be a useful modality for enhancing the diagnostic accuracy of necrotizing enterocolitis and associated complications. The standard imaging algorithm for evaluating necrotizing enterocolitis includes radiographs and clinical symptoms, the combination of which constitutes the Bell criteria. Major limitations of using the Bell criteria for diagnosing and clinically managing necrotizing enterocolitis include low diagnostic accuracy of radiographs and nonspecific symptomatology of preterm infants. In this regard, US can offer additional insights into bowel health by helping to characterize bowel motility, echogenicity, thickness, pneumatosis and perfusion. Extramural findings such as portal venous gas, nature and extent of ascites, and pneumoperitoneum can also be assessed. Recently, contrast-enhanced US was explored in a case series of preterm bowel disease and its diagnostic utility warrants further investigation. This article reviews the US features of necrotizing enterocolitis and highlights the role of US as a complement to radiographs, as well as the emerging use of contrast-enhanced US in necrotizing enterocolitis.

Artificial Intelligence Algorithm Improves Radiologist Performance in Skeletal Age Assessment: A Prospective Multicenter Randomized Controlled Trial.

Background Previous studies suggest that use of artificial intelligence (AI) algorithms as diagnostic aids may improve the quality of skeletal age assessment, though these studies lack evidence from clinical practice. Purpose To compare the accuracy and interpretation time of skeletal age assessment on hand radiograph examinations with and without the use of an AI algorithm as a diagnostic aid. Materials and Methods In this prospective randomized controlled trial, the accuracy of skeletal age assessment on hand radiograph examinations was performed with (n = 792) and without (n = 739) the AI algorithm as a diagnostic aid. For examinations with the AI algorithm, the radiologist was shown the AI interpretation as part of their routine clinical work and was permitted to accept or modify it. Hand radiographs were interpreted by 93 radiologists from six centers. The primary efficacy outcome was the mean absolute difference between the skeletal age dictated into the radiologists' signed report and the average interpretation of a panel of four radiologists not using a diagnostic aid. The secondary outcome was the interpretation time. A linear mixed-effects regression model with random center- and radiologist-level effects was used to compare the two experimental groups. Results Overall mean absolute difference was lower when radiologists used the AI algorithm compared with when they did not (5.36 months vs 5.95 months; P = .04). The proportions at which the absolute difference exceeded 12 months (9.3% vs 13.0%, P = .02) and 24 months (0.5% vs 1.8%, P = .02) were lower with the AI algorithm than without it. Median radiologist interpretation time was lower with the AI algorithm than without it (102 seconds vs 142 seconds, P = .001). Conclusion Use of an artificial intelligence algorithm improved skeletal age assessment accuracy and reduced interpretation times for radiologists, although differences were observed between centers.

Clinical and radiological characteristics of e-cigarette or vaping product use associated lung injury.

PURPOSE: E-cigarette or vaping product use associated lung injury (EVALI) has received national attention as an epidemic resulting in cases of significant morbidity and mortality. We aim to present the clinical and imaging findings in adolescents with pulmonary symptoms from suspected EVALI. METHODS: Chest radiographs and CTs of adolescents (< 19 years) with acute pulmonary symptoms and history of vaping were reviewed by two radiologists in consensus. Clinical presentation and laboratory data were derived from the electronic medical records including pulmonary function tests (PFTs). RESULTS: Eleven patients were identified (9 male, mean 16.6 years). The most common presentation was progressive, subacute respiratory distress with abdominal pain. All but one of the patients tested positive for tetrahydrocannabinol. Chest radiograph features were notable for interstitial pattern of opacities (91%) and basilar abnormalities (82%). CT features were notable for ground-glass opacities (89%), interstitial opacities (78%), and subpleural sparing (67%). Eight patients underwent PFTs. Six had diffusing capacity measurement, which demonstrated impaired diffusion in 3 (50%). All patients received supportive treatment with supplemental oxygen and corticosteroids. CONCLUSION: Adolescents with suspected EVALI commonly present with subacute respiratory distress with abdominal pain. Imaging findings include ground-glass opacities, subpleural sparing, and basilar opacities, most consistent with organizing pneumonia or hypersensitivity pneumonitis. Recognition of the common imaging findings may have significant patient management implications, especially if the diagnosis is not suspected clinically. The lung function effects of vaping are consistent with mildly reduced airflow, which improves on follow-up testing, and reduced diffusion capacity, which, concerningly, does not improve.

Improved Diagnostic Sensitivity of Bowel Disease of Prematurity on Contrast-Enhanced Ultrasound.

Bowel diseases of prematurity, including necrotizing enterocolitis, are dreaded ailments of neonates. Early diagnosis is difficult, with clinical and radiographic findings often inconclusive. We present a novel use of contrast-enhanced ultrasound in detection of pediatric bowel disease. Early identification of compromised blood flow or an at-risk bowel can be quantitatively detected and monitored. This ability has implications for guidance of emerging therapies, allowing targeting of inflammation. These findings represent an advancement in detection of bowel disease in neonates.

Monoclonal TCR-redirected tumor cell killing.

T cell immunity can potentially eradicate malignant cells and lead to clinical remission in a minority of patients with cancer. In the majority of these individuals, however, there is a failure of the specific T cell receptor (TCR)­mediated immune recognition and activation process. Here we describe the engineering and characterization of new reagents termed immune-mobilizing monoclonal TCRs against cancer (ImmTACs). Four such ImmTACs, each comprising a distinct tumor-associated epitope-specific monoclonal TCR with picomolar affinity fused to a humanized cluster of differentiation 3 (CD3)-specific single-chain antibody fragment (scFv), effectively redirected T cells to kill cancer cells expressing extremely low surface epitope densities. Furthermore, these reagents potently suppressed tumor growth in vivo. Thus, ImmTACs overcome immune tolerance to cancer and represent a new approach to tumor immunotherapy.

Throwing workload and injury risk in elite cricketers.

OBJECTIVE: To investigate the risk between throwing workload and upper limb injury in elite cricketers. DESIGN: Prospective cohort study. SETTING: Elite Australian cricket. PARTICIPANTS: 28 adult male cricketers aged 18-32 years. ASSESSMENT OF RISK FACTORS: Daily throwing workload and injury were prospectively monitored over the 2007-2008 cricket season. Risk ratios (RRs) were calculated to describe the association between throwing workload and injury. MAIN OUTCOME MEASUREMENT: Upper limb injury associated with throwing. RESULTS: Seven (25%) players sustained an injury during the season. Injured players threw approximately 40 more throws/week (p=0.004) and 12.5 more throws per throwing day (p=0.061) than uninjured players. Players were at a significantly increased risk of injury if they completed more than 75 throws/week (RR=1.73, 95% CI=1.03 to 2.92), and there was a trend towards an increased risk if they completed more than 40 throws per throwing day (RR=1.41, 95% CI=0.88 to 2.26). Injured players also completed more throws and had more throwing days (and consequently less rest days) in the week before injury, as compared with the rest of their season preceding that point. CONCLUSION: An increased throwing workload is a risk factor for the development of upper limb injury in elite cricketers. Investigation of the kinematics of throwing in elite cricketers would complement this study, and further research is required to develop detailed throwing workload guidelines for cricketers across a range of ages.

Understanding perceptions of injury risk associated with playing junior cricket.

Preventing sports injuries in children is important, but there is limited information about children's perceptions of injury risk or their injury beliefs and attitudes. This study investigated injury risk perceptions in a sample of junior sports participants across different age levels of play. Junior cricket players (n=284, aged 8-16) completed a survey about their injury risk perceptions. Survey questions asked about players' perceived injury risk to themselves compared to cricketers in general, as well as their perceived injury risk across different playing position, ground condition, and protective equipment use scenarios. Chi-square analysis found that risk perceptions were significantly higher in U12 and U14 players for both batting and fielding compared to U16 players and that U16 players had a higher risk perception associated with bowling. Players tended to see themselves as less likely to be injured than cricketers in general and perceived there to be a high risk of injury when fielding close to the batter and a comparatively low risk of injury when fielding in the outfield. Junior players also perceived there to be a high injury risk associated with playing on hard and bumpy grounds. Despite their relatively accurate perceptions of risk and appreciation for the importance of protective equipment, junior players need continual reminding of the importance of safety strategies by coaches and others. Coaches need to inform players that fielding injuries can occur anywhere on the ground, and include skills practice accordingly.

Evaluation of coping resources and self-esteem as moderators of the relationship between threat appraisals and avoidance of activities after traumatic brain injury.

It is not uncommon for people after a traumatic brain injury (TBI) to develop anxieties about possible negative outcomes (i.e., threat appraisals) in relation to participating in valued activities. Some respond to this anxiety by avoiding the activities, but others maintain their participation. The present study investigated two factors that may help explain this variation across individuals in their response to threat appraisals - self-esteem and the evaluation of coping resources. Forty-one individuals with a TBI completed the Avoidance and Threat Appraisals Questionnaire, the Rosenberg Self-Esteem Scale and the Coping Resources Questionnaire. The study's hypotheses were supported: Those low in self-esteem, and those with a negative evaluation of their ability to cope with the TBI, were significantly more likely to respond to threat appraisals with avoidance. Those whose injury was more recent and those whose injury was the result of an assault were also more likely to respond with avoidance. The theoretical and therapeutic implications of these results are discussed.

High affinity soluble ILT2 receptor: a potent inhibitor of CD8(+) T cell activation.

Using directed mutagenesis and phage display on a soluble fragment of the human immunoglobulin super-family receptor ILT2 (synonyms: LIR1, MIR7, CD85j), we have selected a range of mutants with binding affinities enhanced by up to 168,000-fold towards the conserved region of major histocompatibility complex (MHC) class I molecules. Produced in a dimeric form, either by chemical cross-linking with bivalent polyethylene glycol (PEG) derivatives or as a genetic fusion with human IgG Fc-fragment, the mutants exhibited a further increase in ligand-binding strength due to the avidity effect, with resident half-times (t(1/2)) on the surface of MHC I-positive cells of many hours. The novel compounds antagonized the interaction of CD8 co-receptor with MHC I in vitro without affecting the peptide-specific binding of T-cell receptors (TCRs). In both cytokine-release assays and cell-killing experiments the engineered receptors inhibited the activation of CD8(+) cytotoxic T lymphocytes (CTLs) in the presence of their target cells, with subnanomolar potency and in a dose-dependent manner. As a selective inhibitor of CD8(+) CTL responses, the engineered high affinity ILT2 receptor presents a new tool for studying the activation mechanism of different subsets of CTLs and could have potential for the development of novel autoimmunity therapies.

Development and feasibility assessment of telephone-delivered supportive care to improve outcomes for patients with colorectal cancer: pilot study of the CONNECT intervention.

GOALS OF WORK: This study aims to describe a pilot study of the feasibility, acceptability and likely impact of a nurse-delivered, telephone intervention to reduce unmet need and improve quality of life for surgical patients with colorectal cancer. MATERIALS AND METHODS: The CONNECT intervention comprises five standardised calls over 6 months commencing on day 3 post-discharge. A prospective non-randomised control trial with patients who had surgery for colorectal cancer at Royal Prince Alfred Hospital, Sydney between July and December 2006 was conducted. Patients completed a telephone interview with an independent researcher at 1, 3 and 6 months to assess study outcomes, including unmet need (Supportive Care Needs Survey), psychological distress and quality of life (FACT-C). Patients' views of the intervention were ascertained. MAIN RESULTS: Forty-one patients participated, 20 in the intervention period. Intervention calls were successfully completed with 85% or more of patients at each of the five time points. Mean call duration ranged from 14-19 min with the highest number of needs (27 for 20 patients) identified on day 3. Patients indicated that the timing of the calls was appropriate and the majority (85%) felt the number of calls was sufficient. There were promising trends in outcomes. For both patient groups, there were clinically meaningful improvements in FACT-C scores over time, with a larger improvement in the intervention group (20.4 points) than the control group (11.7). CONCLUSIONS: The CONNECT intervention was found to be feasible and acceptable to patients. A larger randomised trial is underway to establish its effectiveness to improve patient outcomes.

Fielders and batters are injured too: a prospective cohort study of injuries in junior club cricket.

Internationally, there is a lack of good quality, prospectively collected injury data reported for junior club cricketers. This study describes injury rates according to age level of play and playing positions in junior community-level club cricketers to identify priorities for prevention. A prospective cohort study was used to monitor injuries in 88 under 12 years (U12), 203 U14 and 120 U16 players from the Ballarat Junior Cricket Association, Australia over the 2007/2008 playing season. Injury rates were calculated per 1000 participations when batting, bowling or fielding in matches and training sessions. Injury rate ratios were used to compare rates across age levels of play and position of play. Overall, 47 injuries were reported. Injury rates increased with age level of play with only one U12 player injured. Match injury rates were 3.57 per 1000 U14 participations versus 4.80 per 1000 U16 participations. Training injury rates were 4.20 per 1000 U14 participations versus 5.11 per 1000 U16 participations. On a proportionate basis, injuries occurred equally to fielders, batters and bowlers. There was a trend towards more injuries occurring while batting and fielding in matches, and more injuries occurring while bowling and batting during training sessions. In conclusion, injury rates in junior cricket players are low, but increase with age level of play. Unlike adult forms of the game, injuries occur to fielders and batters at least as frequently as to bowlers, indicating that preventive strategies need to be developed for all junior players and not just bowlers, as has been the focus previously.

Preferences for outcomes of treatment for rectal cancer: patient and clinician utilities and their application in an interactive computer-based decision aid.

PURPOSE: To quantify the importance that patients and clinicians assign to specific quality-of-life outcomes associated with the treatment of rectal cancer and to demonstrate a clinical application of these data in a computer-based multidimension decision aid (Annalisa). METHODS: For patients, a researcher-administered questionnaire using the time trade-off method was used to quantify the importance of nine outcomes. Information was ascertained from clinicians by use of a self-administered questionnaire. Responses were ranked and compared between groups. Mean values for each outcome were entered into Annalisa. RESULTS: Overall, 103 patients, 87 colorectal surgeons, 97 medical oncologists, and 80 radiation oncologists participated. For all groups, local cancer recurrence in the pelvis and fecal incontinence (mean utility scores 0.53 and 0.57, respectively) were the two outcomes to most avoid. In Annalisa, the "best fit" treatment for patients and surgeons was a low anterior resection with postoperative chemotherapy, whereas for medical and radiation oncologists the best-fit treatment was surgery alone. CONCLUSION: Local recurrence and fecal incontinence are considered the worst outcomes by patients and clinicians alike, but values for other outcomes vary. Decision aids that incorporate patients' individual values with evidence-based data hold considerable potential to optimize treatment decision-making.

Soft landings: encouraging compliance with safety standards in Local Government Authority playgrounds.

ISSUES ADDRESSED: Consistent with health promotion principles of good practice, addressing playground injury necessitates the creation of a supportive environment for the enhancement of wellbeing and the prevention of injuries. This study aims to survey local governments to: determine compliance with playground safety standards; establish frequency of playground inspections and maintenance; and identify motivators and barriers to compliance with safety standards. METHODS: A survey of key informants for playground safety in all 152 local government councils in New South Wales (NSW) was undertaken. RESULTS: Of 152 local councils in NSW (43 metropolitan and 109 non-metropolitan), 71.7% (n=109) completed the survey, 12.5% (n=19) refused to participate and no response was received by 15.8% (n=24). Self-reported compliance with key aspects of the standard was generally high. However, only 55% of councils complied with surface impact attenuation <200 gmax and <1,000 HIC. Further, only 14.7% of councils reported impact testing the playground surface during inspections. The main motivators to compliance included: reducing risk of litigation or liability; enhancing community and child safety, and minimising the risk of injury. The main barriers included a lack of: time; personnel, and a lack of adequate and appropriate funding. CONCLUSIONS: Local Government Authorities have a duty of care to ensure the safety of playgrounds in their jurisdiction. They require time, personnel and adequate and appropriate funding in order to achieve this aim.
