Play-Friendly Communities in Nova Scotia, Canada: A Content Analysis of Physical Activity and Active Transportation Strategies.

The Play-Friendly Cities framework describes key municipal actions and indicators which support a community's playability and can positively influence children's health behaviors and quality of life. The purpose of this study was to conduct a content analysis of Nova Scotia physical activity (PA) and active transportation (AT) strategies by applying the playability criteria in the Play-Friendly Cities framework. METHODS: PA and AT strategies from communities across Nova Scotia were assessed using the Play-Friendly Cities framework. Strategy content was analyzed based on indicators across four themes: participation of children in decision making, safe and active routes around the community, safe and accessible informal play environments, and evidence-informed design of formal play spaces. RESULTS: Forty-two (28 PA,14 AT) strategies were reviewed and all included statements reflective of at least one indicator (8 ± 4; range: 1-14). Content about safe and active routes around the community was most prevalent (41 plans, 812 mentions), while participation of children in decision making was least frequently presented (18 plans, 39 mentions). Content about safe and accessible informal play environments (31 plans, 119 mentions) and evidence-informed design of formal play spaces (28 plans, 199 mentions) was also present. CONCLUSIONS: All PA and AT strategies included some content reflective of a Play-Friendly City; however, there was great variability in the number of included indicators. This summary provides key information on opportunities, such as increasing meaningful involvement of children in decision making, that can inform future municipal actions and policies to improve a community's playability.

Follow-up of tetralogy of Fallot patients: tertiary centre versus satellite clinic.

BACKGROUND: Canadian Cardiovascular Society consensus guidelines recommend that tetralogy of Fallot patients be seen by a congenital cardiologist every 2 years. In Atlantic Canada, tetralogy of Fallot patients are followed up at either tertiary or satellite clinics, which are held in the community and attended by paediatric cardiologists. The effectiveness of satellite clinics in congenital cardiac disease follow-up is unproven. Our objective was to compare patient-reported quality of life measures to determine whether these were impacted by the site of follow-up. METHODS: We included patients with tetralogy of Fallot undergoing surgical repair at the Izaak Walton Killam Health Centre from 1 November, 1972 to 31 May, 2002. Quality of life surveys, SF-10 or SF-36v2, were administered to consenting patients. We analysed the subjective health status by patient age and site of follow-up. RESULTS: Of the 184 eligible patients, 72 were lost to follow-up. Of the locatable patients, 61% completed the questionnaires. In all, 90% (101 out of 112) were followed up at recommended intervals. Of the 112 (68%) patients, 76 were followed up at a tertiary clinic. These patients were older, with a mean age of 18.4 years versus 14.7 years, and scored higher on the SF-36 physical component summary (52.6 versus 45.7, p = 0.02) compared with satellite clinic patients. The SF-36 mental component summary scores were similar for patients regardless of the site of follow-up. SF-10 physical and psychosocial scores were similar regardless of the site of follow-up. CONCLUSION: Tetralogy of Fallot patients followed at either satellite or tertiary clinics have similar subjective health status.

Pediatric cardioplegia strategy results in enhanced calcium metabolism and lower serum troponin T.

BACKGROUND: Pediatric myocardium is unique from mature myocardium; thus, the use of adult cardioplegia for pediatric cardiac operations may provide suboptimal myocardial protection. We evaluated our standard adult cardioplegia (AC; modified Buckberg) and a pediatric cardioplegia (PC) solution (del Nido solution, Baxter) in vitro in rat cardiomyocytes and compared short-term outcomes in pediatric cardiac surgical patients. METHODS: Contractions, intracellular calcium, and action potentials were recorded from isolated rat cardiomyocytes exposed to PC or AC, followed by reperfusion. Pediatric patients (n = 118) undergoing cardiac operations using PC (group PC, n = 59) or AC (group AC, n = 59) were matched 1:1 for age, diagnosis, and duration of cardiopulmonary bypass. RESULTS: PC-perfused rat ventricular cardiomyocytes had lower diastolic calcium during cardioplegia and early reperfusion than AC-perfused cardiomyocytes. Cardiomyocytes remained excitable despite introduction of AC but not PC. The mean age in each pediatric group was 3.7 years (range, 3 days to 17 years; p = 0.95). Median serum troponin T levels at intensive care admission were significantly lower in group PC (0.83 +/- 0.25 microg/L) than in group AC (13.8 +/- 12.7 microg/L, p = 0.0001), which persisted at 24 hours postoperatively. There were no significant differences in duration of intubation or length of stay in intensive care or the hospital. CONCLUSIONS: Pediatric cardioplegia is associated with reduced intracellular diastolic calcium during arrest and reperfusion and more complete arrest during exposure in rat cardiomyocytes. Pediatric patients receiving pediatric cardioplegia had reduced troponin T release compared with those receiving adult cardioplegia.

Great mediastinal vein reconstruction using autologous superficial femoral vein superficial femoral vein graft.

BACKGROUND AND AIM: Great mediastinal veins may be reconstructed using autologous, synthetic, or allograft conduits. Autologous conduits have been found superior to other conduit options. The superficial femoral vein (SFV) offers excellent early patency, minimal lower limb morbidity, and ease of harvest without accessory suture lines. Although rarely used, the SFV provides an acceptable alternative for conduit in large vein reconstructions. METHODS: Two recent cases using SFV for great mediastinal vein reconstruction were reviewed and operative technique of vein harvest detailed. RESULTS: This is the first report of successful reconstruction of a left superior vena cava using SFV conduit. Both superior vena cava (SVC) reconstructions reported were perfectly patent at intermediate term follow-up (20 and 14 months) as determined by computed tomography angiogram or magnetic resonance imaging. CONCLUSIONS: Successful and durable reconstruction of the SVC or a persistent left subclavian vein is possible with minimal morbidity using the SFV.
