Mental health and Victorian Aboriginal people: what can data mining tell us?

Nationally, Aboriginal people experience high levels of psychological distress, primarily due to trauma from colonisation. In Victoria, Aboriginal Community Controlled Health Organisations (ACCHOs) provide many services to support mental health. The aim of the present study was to improve understanding about Victorian Aboriginal people and mental health service patterns. We located four mental health administrative datasets to analyse descriptively, including Practice Health Atlas, Alcohol and Other Drug Treatment Service (AODTS), Kids Helpline and Close The Gap Pharmaceutical Scheme data. A large proportion of the local Aboriginal population (70%) were regular ACCHO clients; of these, 21% had a mental health diagnosis and, of these, 23% had a Medicare Mental Health Care Plan (MHCP). There were higher rates of Medicare MHCP completion rates where general practitioners (GPs) had mental health training and the local Area Mental Health Service had a Koori Mental Health Liaison Officer. There was an over-representation of AODTS episodes, and referrals for these episodes were more likely to come through community, corrections and justice services than for non-Aboriginal people. Aboriginal episodes were less likely to have been referred by a GP or police and less likely to have been referrals to community-based or home-based treatment. There was an over-representation of Victorian Aboriginal calls to Kids Helpline, and these were frequently for suicide and self-harm reasons. We recommend primary care mental health programs include quality audits, GP training, non-pharmaceutical options and partnerships. Access to appropriate AODTS is needed, particularly given links to high incarcerations rates. To ensure access to mental health services, improved understanding of mental health service participation and outcomes, including suicide prevention services for young people, is needed.

Review article: Prehospital fluid management in traumatic brain injury.

The early management of patients who have sustained traumatic brain injury is aimed at preventing secondary brain injury through avoidance of cerebral hypoxia and hypoperfusion. Especially in hypotensive patients, it has been postulated that hypertonic crystalloids and colloids might support mean arterial pressure more effectively by expanding intravascular volume without causing problematic cerebral oedema. We conducted a systematic review to investigate if hypertonic saline or colloids result in better outcomes than isotonic crystalloid solutions, as well as to determine the safety of minimal volume resuscitation, or delayed versus immediate fluid resuscitation during prehospital care for patients with traumatic brain injury. We identified nine randomized controlled trials and one cohort study examined the effects of hypertonic solutions (with or without colloid added) for prehospital fluid resuscitation. None has reported better survival and functional outcomes over the use of isotonic crystalloids. The only trial of restrictive resuscitation strategies was underpowered to demonstrate its safety compared with aggressive early fluid resuscitation in head injured patients, and maintenance of cerebral perfusion remains the top priority.

A pilot study of Aboriginal health promotion from an ecological perspective.

BACKGROUND: For health promotion to be effective in Aboriginal and Torres Strait Islander Communities, interventions (and their evaluation) need to work within a complex social environment and respect Indigenous knowledge, culture and social systems. At present, there is a lack of culturally appropriate evaluation methods available to practitioners that are capable of capturing this complexity. As an initial response to this problem, we used two non-invasive methods to evaluate a community-directed health promotion program, which aimed to improve nutrition and physical activity for members of the Aboriginal community of the Goulburn-Murray region of northern Victoria, Australia. The study addressed two main questions. First, for members of an Aboriginal sporting club, what changes were made to the nutrition environment in which they meet and how is this related to national guidelines for minimising the risk of chronic disease? Second, to what degree was the overall health promotion program aligned with an ecological model of health promotion that addresses physical, social and policy environments as well as individual knowledge and behaviour? METHODS: Rather than monitoring individual outcomes, evaluation methods reported on here assessed change in the nutrition environment (sports club food supply) as a facilitator of dietary change and the 'ecological' nature of the overall program (that is, its complexity with respect to numbers of targets, settings and strategies). RESULTS: There were favourable changes towards the provision of a food supply consistent with Australian guidelines at the sports club. The ecological analysis indicated that the design and implementation of the program were consistent with an ecological model of health promotion. CONCLUSIONS: The evaluation was useful for assessing the impact of the program on the nutrition environment and for understanding the ecological nature of program activities.

First case reports of controlled blunt microdissection for percutaneous transluminal angioplasty of chronic total occlusions in peripheral arteries.

Percutaneous transluminal angioplasty (PTA) can fail to revascularize peripheral arteries when a chronic total occlusion (CTO) cannot be crossed by guidewires. This article describes application of a new controlled blunt microdissection (CMD) catheter designed to cross CTOs. Two men presenting with severe claudication had iliac CTOs that resisted crossing with guidewires. Using standard techniques, the CMD catheter was advanced to the CTO. Following attempts to cross the CTO with guidewires, the jaw of the CMD distal assembly was actuated, advancing through the CTO as plaque was blunt-dissected. After angioplasty and stenting, restored distal flow was restored. Ischemic symptoms had not recurred at 1- and 28-month follow-up. The concept of blunt intraluminal microdissection has been applied to convert failing to successful PTA of peripheral arteries. CTOs that had resisted guidewire crossing were successfully crossed using the CMD catheter, allowing treatment by angioplasty and stenting.

Intraluminal blunt microdissection for angioplasty of coronary chronic total occlusions.

This study describes a new approach to crossing coronary chronic total occlusions using controlled blunt microdissection and its successful application to coronary angioplasty in three patients. After guidewire techniques failed to cross the occlusions, the blunt intraluminal microdissection catheter was deployed. Actuation of a hinged jaw on the catheter distal assembly created a channel for the guidewire through the diseased segment, in the true lumen (a right coronary and a left circumflex artery) and subintimally (a circumflex artery), to allow angioplasty and stenting. Coronary circulation improved from TIMI grade 0 to 3. Angina was relieved in all three cases. Subsequent angiography for two cases, 2 and 19 months after PTCA, respectively, showed restored flow and patent stented regions.
