Simulated impacts of climate change on current farming locations of striped catfish (Pangasianodon hypophthalmus; Sauvage) in the Mekong Delta, Vietnam

In Vietnam, culturing striped catfish makes an important contribution to the Mekong Delta's economy. Water level rise during rainy season and salt intrusion during dry season affect the water exchange and quality for this culture. Sea level rise as a consequence of climate change will worsen these influences. In this study, water level rise and salt water intrusion for three sea level rise (SLR) scenarios (i.e., +30, +50, and +75 cm) were simulated. The results showed that at SLR +50, the 3-m-flood level would spread downstream and threaten farms located in AnGiang, DongThap and CanTho provinces. Rising salinity levels for SLR +75 would reduce the window appropriate for the culture in SocTrang and BenTre provinces, and in TienGiang's coastal districts. Next to increasing dikes to reduce the impacts, the most tenable and least disruptive option to the farming community would be to shift to a salinity tolerant strain of catfish.

Do the numbers and locations of road-killed anuran carcasses accurately reflect impacts of vehicular traffic?

Road-killed animals are easy and inexpensive to survey, and may provide information about species distributions, abundances, and mortality rates. As with any sampling method, however, we need to explore methodological biases in such data. First, how does an animal's behavior (e.g., use of the center vs. periphery of the road) influence its vulnerability to vehicular traffic? Second, how rapidly do post-mortem processes (scavenging by other animals, destruction or displacement by subsequent vehicles) change the numbers and locations of roadkills? Our surveys of anurans on a highway in tropical Australia show that different anuran species are distributed in different ways across the width of the road, and that locations of live versus dead animals sometimes differ within a species. Experimental trials show that location on the road affects the probability of being hit by a vehicle, with anurans in the middle of the road begin hit 35% more often than anurans on the edges; thus, center-using species are more likely to be hit than edge-using taxa. The magnitude of post-mortem displacement and destruction by subsequent vehicles depended on anuran species and body size. The mean parallel displacement distance was 122.7 cm, and carcasses of thin-skinned species exhibited greater post-mortem destruction. Scavenging raptors removed 73% of carcasses, most within a few hours of sunrise. Removal rates were biased with respect to size and species. Overall, our studies suggest that investigators should carefully evaluate potential biases before using roadkill counts to estimate underlying animal abundances or mortality rates.

Comparison of a traditional and non-traditional residential care facility for persons living with dementia and the impact of the environment on occupational engagement

BACKGROUND: Dementia residential facilities can be described as traditional or non-traditional facilities. Non-traditional facilities aim to utilise principles of environmental design to create a milieu that supports persons experiencing cognitive decline. This study aimed to compare these two environments in rural Australia, and their influence on residents' occupational engagement. METHODS: The Residential Environment Impact Survey (REIS) was used and consists of: a walk-through of the facility; activity observation; interviews with residents and employees. Thirteen residents were observed and four employees interviewed. Resident interviews did not occur given the population diagnosis of moderate to severe dementia. Descriptive data from the walk-through and activity observation were analysed for potential opportunities of occupational engagement. Interviews were thematically analysed to discern perception of occupational engagement of residents within their facility. RESULTS: Both facilities provided opportunities for occupational engagement. However, the non-traditional facility provided additional opportunities through employee interactions and features of the physical environment. Interviews revealed six themes: Comfortable environment; roles and responsibilities; getting to know the resident; more stimulation can elicit increased engagement; the home-like experience and environmental layout. These themes coupled with the features of the environment provided insight into the complexity of occupational engagement within this population. CONCLUSION: This study emphasises the influence of the physical and social environment on occupational engagement opportunities. A non-traditional dementia facility maximises these opportunities and can support development of best-practice guidelines within this population.

A university-based clinical exercise facility that serves as a clinical, teaching and research space

Deakin University opened its Clinical Exercise Learning Centre (CELC) in May 2011, initially staffed by four (now seven) Accredited Exercise Physiologists (AEP), and funded by the university. The main objectives of CELC are to provide (i) excellent clinical practicum learning opportunities for postgraduate students enrolled in the Master of Clinical Exercise Physiology that prepare students for subsequent external placements; (ii) learning opportunities that are vertically integrated with the preparatory components of the Masters, including pathophysiology units and pre-clinical units; (iii) learning opportunities that are also integrated with the external clinical practicum program that is embedded in the Masters; (iv) a clinical service to the community and strong referral networks with local GPs; (v) a research centre that is focussed on evaluating the efficacy of Accredited Exercise Physiology (AEP) services for a range of clinical situations, with a view to contributing to a future national evidence-based practice network supported by ESSA. Deakin University funds the CELC facility, equipment, consumables, limited car parking, practice management software and server and, most importantly, the staff. Therefore CELC runs at a loss even against fees charged and this was built into the original model. Staff include an AEP clinical practicum coordinator, two casual AEPs and several academic AEPs; the latter practise as a small part of their approved workloads. The practice model is for all AEPs to provide clinical services with referred clients who are billed as if CELC is a private practice, whilst concurrently teaching and mentoring students; the latter are expected to be active learners in CELC and have exposure to a wide range of pathologies and clinical situations. Billable hours are always provided by AEPs, not students, but students can assist. CELC provides clinical services 1:1:1 (client: AEP: student), 1:1:5 and 8:1:5. CELC was awarded national runner-up in the ESSA Exercise Physiology clinic of the year in 2011 and has grown its caseload to > 200 referrers in 2013. CELC recently designed a generic research platform and has begun to roll out research projects that are designed to translate 'traditional' research-based evidence of exercise benefits for chronic disease in order to evaluate AEP efficacy of practice in the Australian context. CELC provides a model for other universities, provided those universities see it for its learning value, and not to generate revenue or profit.

Fast food restaurant locations according to socioeconomic disadvantage, urban-regional locality, and schools within Victoria, Australia

Features of the built environment provide opportunities to engage in both healthy and unhealthy behaviours. Access to a high number of fast food restaurants may encourage greater consumption of fast food products. The distribution of fast food restaurants at a state-level has not previously been reported in Australia. Using the location of 537 fast food restaurants from four major chains (McDonald[U+05F3]s, KFC, Hungry Jacks, and Red Rooster), this study examined fast food restaurant locations across the state of Victoria relative to area-level disadvantage, urban-regional locality (classified as Major Cities, Inner Regional, or Outer Regional), and around schools. Findings revealed greater locational access to fast food restaurants in more socioeconomically disadvantaged areas (compared to areas with lower levels of disadvantage), nearby to secondary schools (compared to primary schools), and nearby to primary and secondary schools within the most disadvantaged areas of the major city region (compared to primary and secondary schools in areas with lower levels of disadvantage). Adjusted models showed no significant difference in location according to urban-regional locality. Knowledge of the distribution of fast food restaurants in Australia will assist local authorities to target potential policy mechanisms, such as planning regulations, where they are most needed.

Transitioning from caregiver to visitor in a long-term care facility: the experience of caregivers of people with dementia

Objectives: Transitioning from the primary caregiver to the visitor in a long-term care facility may be challenging for the caregiver; they are required to surrender their caring duties to the medical and nursing staff. The aim of this study was to explore the experiences of caregivers during their transition from day-to-day caregiver of a person with dementia to a visitor in a long-term care facility.

Methods: This study utilised a qualitative descriptive design. Twenty caregivers of people with dementia were recruited from the one Aged Rehabilitation and Geriatric Evaluation and Management facility, located in Victoria, Australia. Semi-structured interviews were used to explore the caregiver's experiences. Interviews were analysed using thematic analysis.

Results: The interview data revealed that the participants were undergoing similar experiences. The findings revealed that it was difficult for the caregiver to transition to their new role of visitor; negative reactions of grief, loss of motivation and loneliness were also coupled with positive feelings of relief and the reassurance that their relative or friend would be well cared for and safe within the long-term care facility.

Conclusion: The findings offer insight into the experiences felt by caregivers when their relative or friend with dementia is admitted to hospital. Implications of this study include the need to improve the transition process for the caregiver by allowing them to be involved in the decision-making process, keeping them informed of care decisions, and importantly, providing emotional support to help the caregiver positively adapt to this transition.

End-of-life care in an Australian rehabilitation facility for older people: staff focus groups

A qualitative study of staff experiences of end-of-life care for older people in a subacute rehabilitation facility was undertaken using three focus groups with senior multidisciplinary staff (5), junior nurses (8), and junior allied health staff (7). Content analysis revealed four major themes: being a key contact person; the quality of end–of-life care; referring to off-site service providers; and differing perspectives. These data have implications for multidisciplinary practice including staff education and capacity to change focus of care in facilities for older people dedicated to rehabilitation rather than palliation or end-of-life care.

Transferring from an acute hospital and settling into a subacute facility: the experience of patients with dementia

Background.  In a Melbourne metropolitan health network, patients with dementia can have difficulty settling into a subacute rehabilitation facility after transfer from the acute hospital.

Aims and objectives.  To understand how older patients with mild to moderate dementia experienced the transfer from acute to subacute care and settling-in period.

Design.  A descriptive design was used. Eight patients with mild to moderate dementia were recruited, one to 5 days after transfer.

Method.  A qualitative method using in-depth interviews was used. The data were analysed using content analysis.

Results.  Four main themes were identified: ‘Settling into a new environment’, ‘staff attitudes to people with dementia’, ‘loss of control’ and ‘family support’.

Conclusions.  Person-centred care that comes from the perspective of respect for the individual transcends all these issues. People with dementia require more support to settle after transfer. Family involvement can assist in facilitating a smooth transition.

Implications for practice.  Nurses who understand the specific needs of patients with dementia can develop ways of working with patients to ensure person-centred care. More conversations with people with dementia are needed to investigate how this can be achieved. Orientation procedures should ensure that support for people with dementia is optimized during the settling-in phase.

Variations in area-level disadvantage of Australian registered fitness trainers usual training locations

BACKGROUND: Leisure-time physical activity and strength training participation levels are low and socioeconomically distributed. Fitness trainers (e.g. gym/group instructors) may have a role in increasing these participation levels. However, it is not known whether the training location and characteristics of Australian fitness trainers vary between areas that differ in socioeconomic status.

METHODS: In 2014, a sample of 1,189 Australian trainers completed an online survey with questions about personal and fitness industry-related characteristics (e.g. qualifications, setting, and experience) and postcode of their usual training location. The Australian Bureau of Statistics 'Index of Relative Socioeconomic Disadvantage' (IRSD) was matched to training location and used to assess where fitness professionals trained and whether their experience, qualification level and delivery methods differed by area-level disadvantage. Linear regression analysis was used to examine the relationship between IRSD score and selected characteristics adjusting for covariates (e.g. sex, age).

RESULTS: Overall, 47 % of respondents worked in areas within the three least-disadvantaged deciles. In contrast, only 14.8 % worked in the three most-disadvantaged deciles. In adjusted regression models, fitness industry qualification was positively associated with a higher IRSD score (i.e. working in the least-disadvantaged areas) (Cert III: ref; Cert IV β:13.44 [95 % CI 3.86-23.02]; Diploma β:15.77 [95 % CI: 2.17-29.37]; Undergraduate β:23.14 [95 % CI: 9.41-36.86]).

CONCLUSIONS: Fewer Australian fitness trainers work in areas with high levels of socioeconomic disadvantaged areas than in areas with low levels of disadvantage. A higher level of fitness industry qualifications was associated with working in areas with lower levels of disadvantage. Future research should explore the effectiveness of providing incentives that encourage more fitness trainers and those with higher qualifications to work in more socioeconomically disadvantaged areas.
