Comparison of forehead and finger oximetry sensors during the six minute walk test.

BACKGROUND: Measurement of oxygen saturation (SpO2) during the 6 minute walk test (6MWT) could be impacted by the measurement site. AIMS: To compare SpO2 and heart rate (HR) between forehead and finger sensors during the 6MWT. Sensor readings were also to be compared for signal quality and with capillary blood gas (CBG) pre and post 6MWT. METHOD: 80 subjects with pulmonary vascular disease (PVD) and/or interstitial lung disease (ILD) performed the 6MWT. Pulse oximetry was recorded at 30 s intervals. CBG was taken pre and post 6MWT to determine capillary oxygen saturation (SCO2). RESULTS: The forehead sensor recorded higher values for SpO2 (p < 0.001) and HR (p < 0.01) compared with the finger sensor during the 6MWT. For both sensors, the demonstrated bias compared to CBG post 6MWT was higher and more variable in subjects who desaturated. During the 6MWT there was a higher occurrence (p < 0.001) of poor signal quality in the finger sensor compared with the forehead sensor. CONCLUSION: This study suggests that the sensor site can impact pulse oximetry readings. The variance in bias suggests pulse oximetry may not accurately reflect SCO2 measurements particularly in subjects who desaturate during 6MWT.

Recycling 115,369 mobile phones for gorilla conservation over a six-year period (2009-2014) at Zoos Victoria: A case study of 'points of influence' and mobile phone donations.

More than seven billion mobile phones are estimated to be in service globally, with more than a billion older phones likely to be retired. A major barrier to a sustainable circular economy for mobile phones is people's hoarding of their retired phones. Old mobile phones may be refurbished for re-use or ultimately dismantled for possible extraction of elements, including 'conflict' metals such as coltan (containing elements tantalum and niobium), mined in eastern Democratic Republic of Congo and threatening wild populations of eastern Grauer's gorillas (Gorilla beringei graueri). Zoos Victoria cares for western gorillas (Gorilla gorilla gorilla) who served as ambassadors for their Grauer's gorilla counterparts in this community-based social marketing initiative. Through tracking of barcodes on satchels of recycled mobile phones, efficiency of ten different points of influence could be calculated for the 'They're Calling on You' mobile phone recycling community campaign at Zoos Victoria in Australia. Over a six-year period (2009-2014), a total of 115,369 mobile phones were donated. The Courier Collect initiative resulted in 50,883 mobile phone donations (44% of total), followed by the Static Display at Melbourne Zoo, resulting in 29,778 mobile phone donations (26% of total). The number of phones collected for Keeper Talks (at Melbourne Zoo and Werribee Open Range Zoo) was 12,684 (11% of total), and in terms of fostering close connections between visitors and the conservation campaign, keeper talks were effective as one phone was donated for every four people attending a keeper talk at Werribee Open Range Zoo and one phone was donated for every 28 people who attended a keeper talk at Melbourne Zoo. We provide suggestions for future campaigns, so that accurate data capture can allow cost-benefit analyses to be conducted. Our results demonstrate that a conservation-based organisation, in partnership with corporate sponsors and community groups can effectively influenced people's mobile phone recycling behavior, paving the way for international collaborations to maximize scale and impact.

Evaluating the conservation impact of an innovative zoo-based educational campaign: 'Don't Palm Us Off' for orang-utan conservation.

With significant biodiversity loss occurring presently, increased emphasis is being placed upon the capacity of zoos to contribute to species conservation. This paper evaluates an innovative conservation education campaign 'Don't Palm Us Off' implemented at Melbourne Zoo, Australia. This sought to address a lack of public awareness regarding palm oil (the product most threatening the survival of the orang-utan) and to create public support for mandatory labeling of palm oil on food products, allowing for informed consumer purchasing. Communication tools utilized included an educational video presentation played on-site, as well as You Tube video, celebrity ambassadors, and social media. Evaluation took place across four time-points: baseline, mid-point, conclusion (12 months), and follow-up. Zoo visitors (N = 403) were randomly selected whilst visiting the orang-utan exhibit, completing a questionnaire regarding knowledge about orangutans, attitudes toward orangutans, support for palm oil labeling, previous conservation behavior, and intentions for future behavior. Results revealed significant increases in palm oil awareness; attitudes toward orangutans; support for palm oil labeling; and indicating labeling would influence purchasing behavior, at all times relative to baseline (P < 0.01). There were also significant increases in self-reported conservation behavior at the end of the campaign and follow-up (P < 0.05). In excess of 160,000 people additionally signed an associated petition for mandatory palm oil labeling. Overall the findings support the efficacy of this multi-faceted initiative; highlighting the importance of continued innovation in zoo-based conservation education and practice (including the integration of emerging technologies with traditional on-site education) to maximize contributions to species conservation.

Development and evaluation of an educational intervention for general practitioners and staff caring for people with dementia living in residential facilities.

BACKGROUND: Despite high levels of participation in dementia education, general practitioners (GPs) and residential care facility (RCF) staff report perceived learning needs. Small group education, which is flexible, individualized, practical and case-based, is sought. We aimed to develop educational interventions for GPs and RCF staff tailored to meet their perceived educational needs. METHODS: We used a consultative process to develop education programs. A flexible program for RCF staff was developed in 30-minute blocks, which could be combined in sessions of different lengths. The RCF program aimed to facilitate sustainable change by engaging local "Dementia Champions". For GPs, face-to-face and self-directed packages were developed. We collected participant feedback to evaluate the program. RESULTS: GPs and RCF staff were recruited as part of a larger intervention study. Sixteen of the 27 GPs who were offered the dementia education participated. Two of the 16 GPs participated in both learning packages. A total of 45 GP feedback responses were received from 16 GPs: 28 out of 45 GPs (62%) reported that the participants' learning needs were entirely met. Eighteen of 19 facilities offered the intervention participated and 326 RCF staff attended one or more of the 94 RCF education sessions. Feedback was collected from 93 sessions: 1013 out of 1067 RCF staff feedback responses (95%) reported that the session met the participants' learning needs. Qualitative feedback was also strongly positive. CONCLUSION: Participants perceived the education programs as meeting their needs. Despite explicit attempts to provide flexible delivery options, overall participation rates remained low.
