Abstract

Guidelines recommend primary care providers refer children with obesity to behavioral interventions, but given limited program availability, access, and parental engagement, referrals remain rare. We developed telehealth coaching interventions for families whose children received care at a health system in Pennsylvania, United States in 2019-2020. Intervention referrals were facilitated by the pediatrician and/or project team for 6–12-year-old children with obesity following well-child visits. Participants chose one of three 26-week interventions focused on healthy eating, physical activity, or a hybrid clinical/nutrition intervention. Interventions engaged parents as change agents, enhancing self-efficacy to model and reinforce behavior and providing resources to help create a healthy home environment. We enrolled 77 of 183 eligible parent/child dyads. We used mixed methods to evaluate the interventions. Repeated measures models among participants showed significant reductions in obesogenic nutrition behaviors post-intervention and at 1-year follow-up, including a reduction in sugar-sweetened beverage intake of 2.14 servings/week (95% confidence interval: −3.45, −0.82). There were also improvements in obesoprotective nutrition behaviors (e.g., frequency of family meals, parental self-efficacy related to meal management). One year post-baseline, we observed no significant differences in changes in body mass index (BMI) z-scores comparing child participants with matched controls. Given potential impacts of COVID-19 community restrictions on study outcomes, we conducted qualitative interviews with 13 participants during restrictions, which exemplified how disrupted routines constrained children’s healthy behaviors but that intervention participation prepared parents by providing cooking and physical activities at home. Findings support the potential of a telehealth-delivered nutrition intervention to support adoption of healthy weight behaviors.

41. Provisional report on diving-related fatalities in Australian waters 2010

Author

Lippmann, John, Lawrence, Chris, Fock, Andrew, Wodak, Thomas, Jamieson, Scott, Harris, Richard, Walker, Douglas, Lippmann, John, Lawrence, Chris, Fock, Andrew, Wodak, Thomas, Jamieson, Scott, Harris, Richard, and Walker, Douglas

Abstract

INTRODUCTION: An individual case review was conducted of known diving-related deaths that occurred in Australia in 2010. METHOD: The case studies were compiled using statements from witnesses and reports of the police and coroners. In each case, the particular circumstances of the accident and details from the post-mortem examination, where available, are provided. A root cause analysis was made for each case. RESULTS: There were 20 reported fatalities, one less than the previous year. Five of the victims were female (four scuba divers) and 15 were males. Twelve deaths occurred while snorkelling and/or breath-hold diving, seven while scuba diving (one of whom was using a rebreather), and one diver died while using surface supplied breathing apparatus. At least two breath-hold divers likely drowned as a result of apnoeic hypoxia. Cardiac-related issues were thought to have contributed to the deaths of at least three and possibly five snorkellers, and of at least one, possibly two compressed gas divers. CONCLUSIONS: Snorkelling or diving alone, poor supervision, apnoeic hypoxia, pre-existing medical conditions, lack of recent experience and unfamiliar and/or poorly-functioning equipment were features in several deaths in this series. Reducing delays to CT-scanning and autopsy and coroners' reports documenting that the victim of a drowning was snorkelling or scuba diving at the time are aspects of the investigation of these fatalities that could be improved.

42. Structural evolution in self-assembled gels

Abstract

The use of self-assembled gel in biomaterials and drug delivery is an important new area of research, with these novel materials possessing both physical and chemical advantages over current bio-polymers. However, as gel research expands, key elements of the self-assembly process and gel network formation are still poorly understood. If these gels are to be introduced into biological systems, a better model for gelation is needed which incorporates the structural behaviour and molecular interactions, which help define the stability of gels during the initial gelation process and over the long term. A novel family of gelator molecules, tetraalkyl pyromellitamides, were previously thought to be a model gel system and form in a hierarchical process as proposed in literature for other self-assembled gel systems. A range of gels were synthesised and tested to determine the effects of small changes to the molecule on the larger bulk gel. Through AFM and TEM imaging, it was found that the gel system does not follow a linear growth mechanism; instead it is a dynamic material which changes unexpectedly over a week. A large initial structure separates into smaller fibres which ten entangle to form super-structures on the nano-scale. Rheological profiles of the gels showed changes in viscosity and stiffness of the gels as they were aged, along with the differences in the initial gel formation. To examine what is causing these changes in the structure, X-Ray and neutron scattering were used to characterise the individual fibres which make up the larger fibres observed in the microscopy images. This data confirmed that a one-dimensional stacking mechanism was responsible for the fibre formation, and these fibres were effectively stretching out over time. To investigate the inter- and intra-molecular interactions, along with the role of the solvent molecules, a new synthesis was devised to produce per-deuterated gelators. Using solid-state deuterium-NMR, the mobility and orientation of the side-chains was observed, showing that the gelator is dynamic even when immobilized at low temperature.

Abstract

Introduction: An individual case review of known diving-related deaths that occurred in Australia in 2012 was conducted. Method: The case studies were compiled using statements from witnesses and reports of the police and coroners. In each case, the particular circumstances of the accident and details from the post-mortem examination, where available, are provided. Results: There were 26 reported fatalities (four less than the previous year). Only two of the victims were female (one snorkeller and one scuba diver). Fourteen deaths occurred while snorkelling and/or breath-hold diving, 11 while scuba diving and one diver died while using surface supplied breathing apparatus in a commercial pearl diving setting. Two breath-hold divers likely drowned as a result of apnoeic hypoxia. Cardiac-related issues were thought to have contributed to the deaths of at least three and possibly seven snorkellers and four scuba divers. Conclusions: Pre-existing medical conditions; poor organisation, planning and supervision; equipment-related problems; snorkelling or diving alone or with loose buddy oversight and apnoeic hypoxia were features in several deaths in this series.

Lippmann, John, Lawrence, Christopher, Fock, Andrew, Jamieson, Scott, and Harris, Richard

Abstract

Introduction: An individual case review of diving-related deaths reported as occurring in Australia in 2011 was conducted as part of the DAN Asia-Pacific dive fatality reporting project. Method: The case studies were compiled using reports from witnesses, the police and coroners. In each case, the particular circumstances of the accident and, where available, details from the post-mortem examination are provided. A chain of events analysis was conducted for each case. Results: In total, there were 30 reported fatalities (10 more than in 2010). These included 15 snorkel/breath-hold divers, 14 scuba divers and one diver using surface-supplied breathing apparatus. Twenty-four victims were males. The mean age of snorkelling victims was 49.6 (range 23-75) years and compressed gas divers 42.2 (range 23-55) years. Cardiac-related issues were thought to have been the disabling injury in the deaths of at least seven snorkel divers and five scuba divers. Immersion pulmonary oedema was implicated in at least one death; and three fatalities resulted from attacks by marine animals. Two novices died while under instruction/supervision after separation from their instructor in poor visibility. Conclusions: Pre-existing medical conditions, separation and inadequate supervision and seafood collection in areas frequented by marine predators were once again features in several deaths in this series.
