This is a protocol for a Cochrane Review (Intervention).

B A C K G R O U N D Description of the condition Paediatric heart surgery outcomes have improved markedly over time as a result of marginal gains in training, technology and safety systems (Brown 2015; Hoashi 2015; Jacobs 2016; NICOR 2016). This improvement has been particularly notable in the last 20 years: the publication of heart surgery outcomes after the Kennedy Inquiry in the UK has been associated with a large increase in survival for risk-adjusted surgery (Kennedy 2001; Grant 2013). This has been mirrored worldwide (Brown 2015; Hoashi 2015; Jacobs 2016). One area where there is still controversy is corticosteroid use. Paediatric heart surgery with the use of cardiopulmonary bypass results in a systemic inflammatory response; corticosteroids have been widely used to mitigate the potential deleterious effects of this response. The surgical intervention for which corticosteroids are used includes a variety of surgeries performed on the heart and great vessels. In most cases this procedure aims to correct congenital heart diseases (i.e. heart malformations that the child is born with). In most cases (78% in the UK) (NICOR 2016), surgery will take place with the use Cardio-Pulmonary By-1 Prophylactic corticosteroids for paediatric heart surgery with cardiopulmonary bypass (Protocol)

The lack of environmental supports for healthy lifestyles is a potent factor in the high prevalence of noncommunicable diseases among communities experiencing economic disadvantage. Stronger Austin aimed to increase access to free physical activity (PA) and fitness programming (eg, Zumba) in underserved communities in Austin, Texas, via a partnership and interweaving into context approach in which classes are interwoven into settings with widespread access for residents, including clinics, city-supported housing, parks, recreation centers, and schools. We aimed to better understand the PA-related benefits and opportunities for improvement when adult fitness classes are interwoven into community settings. A mixed-methods design guided the study, which included SOFIT (Structured Observation of Fitness Instruction Time) assessments of class PA (n = 160 participants) and qualitative assessment of highlights and recommendations for class improvement via participant focus groups (n = 24), open-ended questionnaires (n = 258), and instructor interviews (n = 6). Findings indicated high levels of class PA (76.9%-86.9% of 1-hour class spent in moderate-to-vigorous PA; mean of 18 participants per class), with positive social connectedness cited as a key benefit. Challenges and best practices of community-based fitness classes are explored. Stronger Austin's partnership and interweaving into context approach represents a promising model for increasing access to fitness classes in underserved communities.
