Active school transport (AST) has declined rapidly in recent decades. While many studies have examined walking, cycling to school has received very little attention. Correlates of cycling are likely to differ to those from walking and cycling enables AST from further distances. This study examined individual, social and environmental factors associated with cycling to school among elementary school-aged children, stratified by gender.

Introduction: Avascular necrosis of femoral head (ANFH) is a progressive disease that often leads to hip joint dysfunction and even disability in young patients. Although the standard treatment, which is core decompression, has the advantage of minimal invasion, the efficacy is variable. Recent studies have shown that implantation of bone marrow containing osteogenic precursors into necrotic lesion of ANFH may be promising for the treatment of ANFH. Methods: A prospective, double-blinded, randomized controlled trial was conducted to examine the effect of bone-marrow buffy coat (BBC) grafting combined with core decompression for the treatment of ANFH. Forty-five patients (53 hips) with Ficat stage I to III ANFH were recruited. The hips were allocated to the control group (core decompression + autologous bone graft) or treatment group (core decompression + autologous bone graft with BBC). Both patients and assessors were blinded to the treatment options. The clinical symptoms and disease progression were assessed as the primary and secondary outcomes. Results: At the final follow-up (24 months), there was a significant relief in pain (P <0.05) and clinical joint symptoms as measured by the Lequesne index (P <0.05) and Western Ontario and McMaster Universities Arthritis Index (P <0.05) in the treatment group. In addition, 33.3% of the hips in the control group have deteriorated to the next stage after 24 months post-procedure, whereas only 8% in the treatment group had further deterioration (P <0.05). More importantly, the non-progression rates for stage I/II hips were 100% in the treatment group and 66.7% in the control group. Conclusion: Implantation of the autologous BBC grafting combined with core decompression is effective to prevent further progression for the early stages of ANFH.

This systematic review aimed to determine the effectiveness of nurse-led cancer survivorship care, compared with existing models of care, on patient reported outcomes for cancer survivors. Randomised and non-randomised controlled trials and controlled before-after studies published in English between 1 January 2007 and 28 July 2017 were identified in bibliographic databases including Medline, Pubmed and PsychINFO. Included studies described nurse-led cancer care after treatment to adults (age ≥18 years) <2 years post treatment completion. Risk of bias was assessed using Joanna Briggs Institute's tools and meta-analysis was undertaken. Twenty one publications were included describing 15 tumour-specific trials involving 3278 survivors of breast (n = 5), gynecological (n = 3), head and neck (n = 2), colorectal (n = 2), upper gastrointestinal (n = 2) and prostate (n = 1) cancers. Seven trials reported quality of life (QoL) using the EORTC QLQ-C30; participants receiving nurse-led care (4-6 months) had better cognitive (4 trials, 463 participants; mean difference [MD] = 4.04 [95% CI, 0.59-7.50]; p = 0.02) and social functioning (4 trials, 463 participants; MD = 3.06 [0.14-5.97]; p = 0.04) but worse appetite loss (3 trials, 354 participants; MD = 4.43 [0.08-8.78]; p = 0.05). After intervention completion, intervention participants had reduced fatigue (4 trials, 647 participants; MD = -4.45 [-7.93 to -0.97]; p = 0.01). This systematic review synthesised outcomes of models of nurse-led survivorship care and contributes a meta-analysis of patient QoL to survivorship evidence. This review was limited by the risk of bias in many included studies for blinding of treatment personnel and outcome assessors. Nurse-led care appears beneficial for cancer survivors for some QoL domains.

Objective This study aimed to examine trends in number of CT scans requested by tertiary emergency department (ED) physicians in Western Australia (WA) from 2003 to 2015 across broad demographic and presentation characteristics, anatomical areas and presented symptoms. Design An observational cross-sectional study over study period from 2003 to 2015. Setting Linked administrative health service data at individual level from WA. Participants A total of 1 666 884 tertiary hospital ED presentations of people aged 18 years or older were included in this study Main outcome measure Number of CT scans requested by tertiary ED physicians in an ED presentation. Methods Poisson regression models were used to assess variation and trends in number of CT scans requested by ED physicians across demographic characteristics, clinical presentation characteristics and anatomical areas. Results Over the entire study duration, 71 per 1000 ED episodes had a CT requested by tertiary ED physicians. Between 2003 and 2015, the rate of CT scanning almost doubled from 58 to 105 per 1000 ED presentations. After adjusted for all observed characteristics, the rate of CT scans showed a downward trend from 2009 to 2011 and subsequent increase. Males, older individuals, those attending ED as a result of pain, those with neurological symptoms or injury or with higher priority triage code were the most likely to have CT requested by tertiary ED physicians. Conclusions Noticeable changes in the number of CTs requested by tertiary ED physicians corresponded to the time frame of major health reforms happening within WA and nationally.

The purpose of this research was to assess agreement between four rating systems of cosmetic outcome measured in a subset of patients with early breast cancer participating in the randomised TARGIT-A trial. TARGIT-A compared risk-adapted single-dose intra-operative radiotherapy (TARGIT-IORT) to whole breast external beam radiotherapy (EBRT). Patients, their Radiation Oncologist and Research Nurse completed a subjective cosmetic assessment questionnaire before radiotherapy and annually thereafter for five years. Objective data previously calculated by the validated BCCT.core software which utilizes digital photographs to score symmetry, colour and scar was also used. Agreement was assessed by the Kappa statistic and longitudinal changes were assessed by generalized estimating equations. Overall, an Excellent-Good (EG) cosmetic result was scored more often than a Fair-Poor (FP) result for both treatment groups across all time points, with patients who received TARGIT-IORT scoring EG more often than those who received EBRT however this was statistically significant at Year 5 only. There was modest agreement between the four rating systems with the highest Kappa score being moderate agreement which was between nurse and doctor scores at Year 1 with Kappa = 0.46 (p < 0.001), 95% CI (0.24, 0.68). Despite similar overall findings between treatment groups and rating systems, the inter-rater agreement was only modest. This suggests that the four rating systems utilized may not necessarily be used interchangeably and it is arguable that for an outcome such as cosmetic appearance, the patient’s point of view is the most important.
