A naturalistic study of treatment outcomes with aripiprazole in young people with first episode psychosis

Objective: Adequate treatment of a first psychotic episode in young people is a difficult challenge but may be of critical importance for changing the course of psychotic illness. Pharmacotherapy is the standard treatment of psychosis, however there is a paucity of data specific to first-episode psychosis.
Methods: In this study 12 young people who presented with a psychotic episode at a specialised early intervention service were commenced on treatment with aripiprazole. They were assessed at baseline and weeks 4, 6, 24 and 48 using a broad battery of outcome measures. Case notes were also examined.
Results: Data was available for 6 participants at week 48, and of those, one remained on treatment with Aripiprazole at endpoint. Case histories were typified by presentations that included illicit substance use and treatments characterised by several changes in medications. No single treatment choice predominated. Most participants tolerated treatment and showed symptomatic improvement with individualised therapy.
Conclusion: Most participants showed improvement during the treatment period. Aripiprazole was one of many medications used in this study and may have been useful for the treatment of some individuals with first episode psychosis.

A comparison of the effectiveness of camera trapping and live trapping for sampling terrestrial small-mammal communities

Context. There is an increasing reliance on the use of camera-trap technologies for surveys of medium to large terrestrial mammals. Camera trapping may, however, also have significant applications for broad-scale surveys of small mammals.
Aims. The present study aims to compare results from camera-trapping surveys to those of the more traditional live trapping techniques. Specifically, it aims to test the effectiveness of the techniques for detecting species, and the cost effectiveness of both approaches.
Methods. Surveys were conducted across 36 sites in the Grampians National Park, Victoria, Australia, between April and July 2009. At each site, independent surveys were conducted for small mammals by using a combination of Elliot and cage trapping, then camera trapping. Results for the two different approaches were compared for both their ability to generate small-mammal presence data and their cost effectiveness.
Key results. Camera-trapping surveys of 36 sites in the Grampians National Park compared favourably with those of live trapping surveys. Similar species were detected across the sites, and camera trapping was a considerably more cost effective than live trapping.
Conclusions. Camera-trapping surveys of small terrestrial mammals may provide a new and cost-effective technique for surveying terrestrial small mammals. This is particularly the case when presence data are the main requirement of the survey, with no requirement to capture and tag animals.
Implications. Given the cost-effective nature of camera trapping, there is potential to use this approach to increase the level of replication and spatial coverage of small-mammal surveys. Improving the replication and spatial coverage of studies has the potential to significantly increase the scope of research questions that can be asked, thus providing the potential to improve wildlife management.

Health professionals' and dietetics practitioners' perceived effectiveness of fruit and vegetable parenting practices across six countries

Fruit and vegetable intake may reduce the risk of some chronic diseases. However, many children consume less-than-recommended amounts of fruit and vegetables. Because health professionals and dietetics practitioners often work with parents to increase children's fruit and vegetable intake, assessing their opinions about the effectiveness of parenting practices is an important step in understanding how to promote fruit and vegetable intake among preschool-aged children. Using a cross-sectional design, collaborators from six countries distributed an Internet survey to health and nutrition organization members. A self-selected sample reported their perceptions of the effectiveness of 39 parenting practices intended to promote fruit and vegetable consumption in preschool-aged children from May 18, 2008, to September 16, 2008. A total of 889 participants (55% United States, 22.6% Mexico, 10.9% Australia, 4.4% Spain, 3.3% Chile, 2.2% United Kingdom, and 1.6% other countries) completed the survey. The fruit and vegetable intake–related parenting practices items were categorized into three dimensions (structure, responsiveness, and control) based on a parenting theory conceptual framework and dichotomized as effective/ineffective based on professional perceptions. The theoretically derived factor structures for effective and ineffective parenting practices were evaluated using separate confirmatory factor analyses and demonstrated acceptable fit. Fruit and vegetable intake–related parenting practices that provide external control were perceived as ineffective or counterproductive, whereas fruit and vegetable intake–related parenting practices that provided structure, nondirective control, and were responsive were perceived as effective in getting preschool-aged children to consume fruit and vegetables. Future research needs to develop and validate a parent-reported measure of these fruit and vegetable intake–related parenting practices and to empirically evaluate the effect of parental use of the parenting practices on child fruit and vegetable consumption.
