Abstract
Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amount and timing of animal activity varied widely. Under higher human activity, mammals were less active in undeveloped areas but unexpectedly more active in developed areas while exhibiting greater nocturnality. Carnivores were most sensitive, showing the strongest decreases in activity and greatest increases in nocturnality. Wildlife managers must consider how habituation and uneven sensitivity across species may cause fundamental differences in human-wildlife interactions along gradients of human influence.

How do people living with obesity who use obesity services perceive healthcare professionals' representation of the disease on social media? An interpretative phenomenological analysis.

Abstract
OBJECTIVES The objective of this study was to explore how people living with obesity who use obesity services perceive healthcare professionals' (HCPs) online representation of the disease on social media. By exploring their perspective, we aimed to develop a framework to inform good practice around social media use for HCPs. DESIGN This was a qualitative study using a phenomenological framework. Following in-depth semi-structured interviews, analysis was undertaken to identify superordinate themes relating to how HCPs portray living with obesity online. SETTING Patient advocacy organisation (The Irish Coalition for People Living with Obesity) and three clinical sites offering obesity treatment in Ireland. PARTICIPANTS 15 adult participants comprising of 12 women and 3 men who use social media and are living with obesity and who use obesity services. RESULTS Three key themes of how people living with obesity who use obesity services perceive HCP's online representation of the disease. (1) Negative experiences of HCPs-participants describe encountering weight stigma and bias on social media from HCPs that they characterised as simplistic and outdated conceptualisations. These engender shame, fear and anger. (2) Positive experience of HCPs-participants report social media allows HCPs to educate and inform public perception of obesity. Positive online experiences lead to feelings of inclusion, understanding and encouragement. (3) Expectations of HCPs-qualifications, professional titles and academic association affected the perceived trustworthiness of information and its impact on readers. Participants feel there is a duty of care for HCPs in obesity medicine to advocate and be active online to provide accurate medical information. CONCLUSION HCP's use of social media has a powerful impact on people with obesity who use healthcare and obesity services. Social media is a key tool in obesity awareness and education. We propose the '3E' framework-Empower, Evidence-Based and Educate and be educated to guide HCPs' social media use.

Abstract
BACKGROUND Key populations (KPs) such as female sex workers (FSWs), men who have sex with men (MSM), people who inject drugs (PWID), and their partners contribute more than a quarter (27.5%) of new HIV infection in Ghana. Oral pre-exposure prophylaxis (PrEP) can substantially reduce HIV acquisition among this group. While the available research indicates KPs willingness to take PrEP in Ghana, little is known about the position of policymakers and healthcare providers on the introduction of PrEP for KPs. METHODS Qualitative data were collected from September to October 2017 in the Greater Accra (GA) and Brong-Ahafo (BA) regions of Ghana. Key informant interviews were conducted with 20 regional and national policymakers and supplemented with In-depth Interviews with 23 healthcare providers to explore their level of support for PrEP and their perspectives on challenges and issues to consider for oral PrEP implementation in Ghana. Thematic content analysis was used to unearth the issues emerging from the interviews. RESULTS Policymakers and healthcare providers in both regions expressed strong support for introducing PrEP for KPs. Key concerns regarding oral PrEP introduction included potential for behavioral disinhibition, non-adherence and side effects of medication, cost and long-term financial implications, and stigma related to HIV and key populations. Participants stressed the need to integrate PrEP into existing services and the provision of PrEP should start with high risk groups like sero-discordant couples, FSWs and MSM. CONCLUSIONS Policymakers and providers recognize the value of PrEP in cubing new HIV infections but have concerns about disinhibition, non-adherence, and cost. Therefore, the Ghana health service should roll-out a range of strategies to address their concerns including: sensitization with providers to mitigate underlying stigma towards KPs, particularly MSM, integration of PrEP into existing services, and innovative strategies to improve continued use of PrEP.

Abstract
Lately, easier and shorter tests have been used in the functional evaluation of cardiac patients. Among these, walking speed (WS) and Timed Up and Go (TUG) tests are associated with all-cause mortality, mainly cardiovascular and the rate of re-hospitalization, especially in the elderly population. We prospectively analyzed a group of 38 patients admitted to the Cardiology Clinic from Elias Hospital, Romania, with chronic coronary syndrome (CCS) (n=22) and STEMI (n=16). We assessed the patients immediately after admission and before discharge with G-WALK between the 1st and 30th of September 2019. Our study group had a mean age of 62.7±12.1 years. Patients with a low WS were older (69.90±12.84 vs. 59.90±10.32 years, p=0.02) and had a lower serum hemoglobin (12.38±1.20 vs. 13.72±2.07 g/dl, p=0.02). The WS significantly improved during hospitalization (p=0.03) after optimal treatment. The TUG test performed at the time of admission had a longer duration in patients with heart failure (14.05 vs. 10.80 sec, p=0.02) and was influenced by patients' age (r=0.567, p=0.02), serum creatinine (r=0.409, p=0.03) and dilation of right heart chambers (r=0.399, p=0.03). WS and TUG tests can be used in patients with CCS and STEMI, and are mainly influenced by age, thus having a greater value among the elderly.

Purpose Mild cognitive impairment can impact driving performance and self-regulation practices. However, there is little evidence on how cognitive impairment may impact these self-regulation practices over a period of time. Therefore, the aim of this study was to examine changes in the number and type of situations in which older drivers with and without suspected mild cognitive impairment (MCI) self-regulate their driving over a one-year period, after accounting for relevant confounders. Participants and Methods A longitudinal cohort study involving older drivers (65+ years) from metropolitan Western Australia was interviewed by a telephone interview at baseline and one-year follow-up. The Telephone Cognitive Screen (T-CogS) was also administered to determine changes in their cognitive status. The outcome of interest was the number and type of situations older drivers self-regulated their driving. Results A total of 670 drivers were interviewed at baseline (suspected MCI: n = 227; no cognitive impairment: n = 443) and one-year follow-up (suspected MCI: n = 251; no cognitive impairment: n = 419), which provided 1340 observations. Drivers with suspected MCI increased the number of driving situations in which they self-regulated by 13% over a period of one-year compared with drivers without cognitive impairment (IRR = 1.13, 95% CI = 1.02–1.27, p = 0.025). Specifically, drivers with suspected MCI had 60% increased odds of self-regulating when “making turns across oncoming traffic” compared with drivers without cognitive impairment (unadjusted OR = 1.60, 95% CI = 1.02–2.53, p = 0.041). Other significant factors included being female (IRR = 1.87, 95% = 1.52–2.32, p = 0.001), aged 75+ years (IRR = 1.33, 95% CI = 1.10–1.60, p = 0.003), higher number of comorbidities (1–3 comorbidities: IRR = 1.26, 95% CI = 1.01–1.58, p = 0.040; 4+ comorbidities: IRR = 1.39, 95% CI = 1.08–1.78, p = 0.011), “decreased driving confidence” (IRR = 1.32, 95% CI = 1.10–1.58, p-value = 0.003) and “preference of having someone else drive” (IRR = 1.38, 95% CI = 1.12–1.70, p = 0.003). Having one or more traffic infringements was also associated with a decrease in the number of self-regulated driving situations (IRR = 0.80, 95% CI = 0.67–0.95, p = 0.011). Conclusion Over a one-year period, drivers with suspected MCI increased the number of situations in which they self-regulated their driving compared with drivers without cognitive impairment, particularly when “making turns across oncoming traffic”. Future studies should examine whether this increase in the types and number of self-regulated driving situations is enough to compensate for declines in cognition.

Abstract
Purpose Mild cognitive impairment and gender can impact different aspects of driving performance and behaviour in older drivers. However, there is little evidence on how these may affect naturalistic speeding behaviour. Therefore, the aim of this study was to examine the relationship between speeding events and cognitive status for older male and female drivers. Participants and Methods A naturalistic driving study collected objective driving information over a two-week period using an in-vehicle monitoring device from 36 older drivers with suspected mild cognitive impairment and 35 older drivers without cognitive impairment. The outcome of interest examined was the number of speeding events, defined as travelling 5+ km/h over the posted speed limit for at least a minute. Results The majority of participants (n=58, 81.69%) did not have a speeding event during the two-week monitoring period. Twenty-three speeding events were recorded among seven drivers with suspected mild cognitive impairment and six drivers without cognitive impairment. The majority of speeding events (82.61%) were by older male drivers and occurred in 60km/h and 70km/h speed zones. The results of the two negative binomial regression models found that in older male drivers, suspected mild cognitive impairment (IRR=7.45, 95% CI=1.53–36.15, p=0.01) was associated with a significantly higher rate of speeding events, while increasing age was associated with a lower rate of speeding events (IRR=0.80, 95% CI=0.64–1.00, p=0.04). For older female drivers, there were no factors significantly associated with the rate of speeding events. Conclusion While the overall number of speeding events were infrequent, suspected mild cognitive impairment was associated with a significant increase in the rate of speeding events for older male drivers, but not for older female drivers. Speeding interventions and injury prevention policy strategies may need to be targeted differently for male and female drivers with mild cognitive impairment.

Abstract
This article describes an innovative mask consisting of a newly fabricated 3-ply surgical face mask with a custom made attachment consisting of a plastic dome and a oneway valve port that allows endoscopes to be inserted through it. The mask was tested in-vitro with simulated sneezing using fluorescent dyes and also received positive feedbacks from field tests of 30 masks on real users in different hospitals. This innovative mask is useful in providing extra barrier for endoscopic procedures in ENT and can be used beyond this pandemic in patients with other infectious diseases.

Abstract
Fish represents one of the major sources of animal proteins, and different species of fish are susceptible to infections with parasites which cause severe tissue damage and cell destruction of the infected organ. Therefore, in 2019, this parasitological study was conducted to assess the helminth parasites infecting the African sharptooth catfish Clarias gariepinus that were collected from Lake Manzala, Egypt. Only nematode parasite was reported as a prevalent infection from the fish stomach with an infection rate of 7.5%. Depending on the seasonal prevalence, the extent of the infection was analyzed. It was indicated that parasite infection was only reported as 15% in the winter season. Morphological and morphometric analyses of the present parasite species revealed that it possesses all the characteristics of the Camallanus genus, whereas it is closely related to Camallanus polypteri described previously. It is characterized by the presence of a buccal capsule with longitudinal internal ridges, some of which are very short and ranged from 8-14 in males and 8-9 in females. The esophagus consisted of muscular and glandular portions, the middle position of the excretory pore to the muscular esophagus, the anterior location of deirids to the nerve ring, posterior end of males with two unequal spicules and caudal papillae; nonetheless, it is smooth and straight in females. In addition, some morphology and measurement differences for the different body parts were identified with other Camallanus species. Therefore, the present study can provide a full morphologically re-description of Camallanus polypteri with a new geographical location in the Egyptian freshwater.

Abstract
INTRODUCTION There are personal and societal benefits from caregiving; however, caregiving can jeopardise caregivers' health. The Further Enabling Care at Home (FECH+) programme provides structured nurse support, through telephone outreach, to informal caregivers of older adults following discharge from acute hospital care to home. The trial aims to evaluate the efficacy of the FECH+ programme on caregivers' health-related quality of life (HRQOL) after care recipients' hospital discharge. METHODS AND ANALYSIS A multisite, parallel-group, randomised controlled trial with blinded baseline and outcome assessment and intention-to-treat analysis, adhering to Consolidated Standards of Reporting Trials guidelines will be conducted. Participants (N=925 dyads) comprising informal home caregiver (18 years or older) and care recipient (70 years or older) will be recruited when the care recipient is discharged from hospital. Caregivers of patients discharged from wards in three hospitals in Australia (one in Western Australia and two in Queensland) are eligible for inclusion. Participants will be randomly assigned to one of the two groups. The intervention group receive the FECH+ programme, which provides structured support and problem-solving for the caregiver after the care recipient's discharge, in addition to usual care. The control group receives usual care. The programme is delivered by a registered nurse and comprises six 30-45 min telephone support sessions over 6 months. The primary outcome is caregivers' HRQOL measured using the Assessment of Quality of Life-eight dimensions. Secondary outcomes include caregiver preparedness, strain and distress and use of healthcare services. Changes in HRQOL between groups will be compared using a mixed regression model that accounts for the correlation between repeated measurements. ETHICS AND DISSEMINATION Participants will provide written informed consent. Ethics approvals have been obtained from Sir Charles Gairdner and Osborne Park Health Care Group, Curtin University, Griffith University, Gold Coast Health Service and government health data linkage services. Findings will be disseminated through presentations, peer-reviewed journals and conferences. TRIAL REGISTRATION NUMBER ACTRN12620000060943.

Abstract
OBJECTIVE The aim of the study is to compare driving exposure, patterns and factors associated with safety critical events between drivers with MCI and a comparison group without cognitive impairment. DESIGN, SETTING, PARTICIPANTS Naturalistic driving data using an in-vehicle monitoring device were collected from 36 older drivers with MCI and 35 older drivers without cognitive impairment over a two-week period in Western Australia. MEASUREMENTS Naturalistic driving exposure, patterns (eg. night-time trips, peak-hour trips) and safety critical events (harsh acceleration, harsh braking and harsh cornering). RESULTS Drivers with MCI had a lower number of safety critical events (mean = 7.20, SD = 11.44) compared to drivers without cognitive impairment (mean = 10.89, SD = 23.30) however, this was not statistically significantly. There were also no statistically significant differences between drivers with and without MCI for measures of driving exposure or any of the driving patterns including weekday trips, night-time trips and trips on highways/freeways. The results of the multivariable modelling found only binocular contrast sensitivity was associated with the rate of safety critical events. For every increase of 0.1 log units in contrast sensitivity (better contrast sensitivity) the rate of safety critical events significantly decreased by 30 % (IRR = 0.70, 95 % CI = 0.50-0.98, p = 0.04). CONCLUSION Drivers with MCI were found to have similar driving exposure and patterns compared to older drivers without cognitive impairment, however drivers with better contrast sensitivity experienced fewer safety critical events. Future research should consider a longitudinal study design with an extended driving monitoring period and a larger sample with a clinical diagnosis of MCI to assess changes in cognition and its impact on driving.

Abstract
Prevention of device related infections due to Staphylococcus aureus biofilms on devices represents a significant challenge. Such infections have recently been shown to be dependent on the coagulation pathway via activation of pro-thrombin and fibrin production. Three direct-thrombin inhibitors, argatroban, hirudin and dabigatran, were examined to determine their effect on preventing S. aureus biofilm on plastic biochip surfaces under shear stress using an in vivo relevant model of infection. Surface functionalization of polyurethane discs via dityrosine covalent crosslinking with hirudin was performed and changes in bacterial density and microscopic appearances determined. The three direct-thrombin inhibitors prevented S. aureus biofilm formation on plasma-coated surfaces treated with these agents. Coating of polyurethane with one of these agents, hirudin, significantly inhibited biofilm formation on the modified surface. These findings reveal the exciting potential for coating biomaterial surfaces with direct thrombin inhibitors to prevent staphylococcal binding and subsequent device-related infections.

Abstract
In its 33 years, ADDR has published regularly on the po5tential of oral delivery of biologics especially peptides and proteins. In the intervening period, analysis of the preclinical and clinical trial failures of many purported platform technologies has led to reflection on the true status of the field and reigning in of expectations. Oral formulations of semaglutide, octreotide, and salmon calcitonin have completed Phase III trials, with oral semaglutide being approved by the FDA in 2019. The progress made with oral peptide formulations based on traditional permeation enhancers is against a background of low and variable oral bioavailability values of ~1%, leading to a current perception that only potent peptides with a viable cost of synthesis can be realistically considered. Desirable features of candidates should include a large therapeutic index, some stability in the GI tract, a long elimination half-life, and a relatively low clearance rate. Administration in nanoparticle formats have largely disappointed, with few prototypes reaching clinical trials: insufficient particle loading, lack of controlled release, low epithelial particle uptake, and lack of scalable synthesis being the main reasons for discontinuation. Disruptive technologies based on engineered devices promise improvements, but scale-up and toxicology aspects are issues to address. In parallel, medicinal chemists are synthesizing stable hydrophobic macrocyclic candidate peptides of lower molecular weight and with potential for greater oral bioavailability than linear peptides, but perhaps without the same requirement for elaborate drug delivery systems. In summary, while there have been advances in understanding the limitations of peptides for oral delivery, low membrane permeability, metabolism, and high clearance rates continue to hamper progress.

Abstract
BACKGROUND There is an unmet need for routine and accurate prognostication of older adults with end-stage kidney disease (ESKD) and subsequently inadequate advance care planning. Frailty, a clinical syndrome of increased vulnerability, is predictive of adverse health outcomes in the renal population. We propose the Clinical Frailty Scale (CFS) as a feasible tool for routine use in the nephrology outpatient setting to address this unmet need. AIMS To assess feasibility and associations of incorporating CFS assessment into routine outpatient nephrology practice in the pre-dialysis setting. METHODS CFS was integrated into the outpatient nephrology clinic proforma. A convenience sample of 138 patients aged >50 years, with estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2 , attending the outpatient service between September 2018 and April 2019 was included. RESULTS Eighty-one CFS assessments were completed by nephrologists, nephrology advanced trainees and clinical nurse specialists. CFS completion rates were 79% from the multidisciplinary Low Clearance Clinic and 41% from nurse-led Pre-dialysis Education Clinic. Planned modality of ESKD management varied with degree of frailty (P < 0.001). 21% of patients who had CFS completed were planned for Conservative Management of ESKD, in contrast to only 5% of those who did not have CFS assessment completed (P < 0.001). CONCLUSION Frailty assessment via CFS was feasible in outpatient practice when integrated into routine clinical assessment in a dedicated clinic. Planned ESKD management varied with the degree of frailty. Completion of frailty assessment, when compared with non-completion, appears to be associated with increased planned conservative management of ESKD.

Abstract
Objective To assess the impact of cognitive, socio-demographic and driving-related characteristics on self-regulation practices in older drivers with mild cognitive impairment (MCI) (determined by the Telephone Cognitive Screen (T-CogS) score), compared with drivers with no cognitive impairment. Design, Setting, Participants A cross-sectional study collected information from 362 drivers with MCI and 611 drivers with no cognitive impairment, who were aged 65+ years, and were living in Western Australia between November 2018 and February 2019. Measurements Self-reported self-regulation driving practices. Results The majority of drivers with MCI (62.4%) and those with no cognitive impairment (57.1%) reported self-regulating their driving in at least one situation, in the past three months. The most common situations that both groups of drivers self-regulated in were “driving at night in the rain”, “parallel parking”, and “driving when raining”. Drivers with MCI were only significantly more likely to self-regulate when “making turns across oncoming traffic” and “driving at night”. They also had 39% greater odds of self-regulating in at least one driving situation, compared with drivers with no cognitive impairment (OR: 1.39, 95% CI=1.04–1.85, p=0.02). Females also had 2.3 times greater odds of self-regulating (OR=2.34, 95% CI=1.76–3.12, p<0.001). Drivers aged 75+ years had 1.6 times greater odds of self-regulating, compared with drivers aged 65–69 years (OR=1.58, 95% CI=1.12–2.23, p=0.01). Conclusion Older drivers with MCI were more likely to self-regulate their driving, compared to drivers with no cognitive impairment, particularly in complex driving situations. This suggests that some drivers with MCI may be able to recognize their cognitive limitations and adjust their driving accordingly. However, several drivers with MCI, particularly males, did not self-regulate their driving. This highlights the importance of advising patients about the impact of MCI on driving ability, suitable self-regulation strategies, as well as monitoring their driving ability.

Abstract
Much of the basic ecology of Ebolavirus remains unresolved despite accumulating disease outbreaks, viral strains and evidence of animal hosts. Because human Ebolavirus epidemics have been linked to contact with wild mammals other than bats, traits shared by species that have been infected by Ebolavirus and their phylogenetic distribution could suggest ecological mechanisms contributing to human Ebolavirus spillovers. We compiled data on Ebolavirus exposure in mammals and corresponding data on life-history traits, movement, and diet, and used boosted regression trees (BRT) to identify predictors of exposure and infection for 119 species (hereafter hosts). Mapping the phylogenetic distribution of presumptive Ebolavirus hosts reveals that they are scattered across several distinct mammal clades, but concentrated among Old World fruit bats, primates and artiodactyls. While sampling effort was the most important predictor, explaining nearly as much of the variation among hosts as traits, BRT models distinguished hosts from all other species with greater than 97% accuracy, and revealed probable Ebolavirus hosts as large-bodied, frugivorous, and with slow life histories. Provisionally, results suggest that some insectivorous bat genera, Old World monkeys and forest antelopes should receive priority in Ebolavirus survey efforts. This article is part of the theme issue ‘Dynamic and integrative approaches to understanding pathogen spillover’.

Abstract
Patients with schizophrenia show impairment in processing faces, including facial affect and face detection, but the underlying mechanisms are unknown. We used functional magnetic resonance imaging (fMRI) to characterize resting state functional connectivity between an independent component analysis (ICA)-defined early visual cortical network (corresponding to regions in V1, V2, V3) and a priori defined face-processing regions (fusiform face area [FFA], occipital face area [OFA], superior temporal sulcus [STS] and amygdala) using dual regression in 20 schizophrenia patients and 26 healthy controls. We also investigated the association between resting functional connectivity and neural responses (fMRI) elicited by a face detection paradigm in a partially overlapping sample (Maher et al., 2016) that used stimuli equated for lower-level perceptual abilities. Group differences in functional connectivity were found in right FFA only; controls showed significantly stronger functional connectivity to an early visual cortical network. Functional connectivity in right FFA was associated with (a) neural responses during face detection in controls only, and (b) perceptual detection thresholds for faces in patients only. The finding of impaired functional connectivity for right FFA (but not other queried domain-specific regions) converges with findings investigating face detection in an overlapping sample in which dysfunction was found exclusively for right FFA in schizophrenia during face detection.

Abstract
Many drugs have intracellular or membrane-associated targets, thus understanding their interaction with the cell membrane is of value in drug development. Cell-free tools used to predict membrane interactions should replicate the molecular organization of the membrane. Microcavity array-supported lipid bilayer (MSLB) platforms are versatile biophysical models of the cell membrane that combine liposome-like membrane fluidity with stability and addressability. We used an MSLB herein to interrogate drug-membrane interactions across seven drugs from different classes, including nonsteroidal anti-inflammatories: ibuprofen (Ibu) and diclofenac (Dic); antibiotics: rifampicin (Rif), levofloxacin (Levo), and pefloxacin (Pef); and bisphosphonates: alendronate (Ale) and clodronate (Clo). Fluorescence lifetime correlation spectroscopy (FLCS) and electrochemical impedance spectroscopy (EIS) were used to evaluate the impact of drug on 1,2-dioleyl- sn-glycerophosphocholine and binary bilayers over physiologically relevant drug concentrations. Although FLCS data revealed Ibu, Levo, Pef, Ale, and Clo had no impact on lipid lateral mobility, EIS, which is more sensitive to membrane structural change, indicated modest but significant decreases to membrane resistivity consistent with adsorption but weak penetration of drugs at the membrane. Ale and Clo, evaluated at pH 5.25, did not impact the impedance of the membrane except at concentrations exceeding 4 mM. Conversely, Dic and Rif dramatically altered bilayer fluidity, suggesting their translocation through the bilayer, and EIS data showed that resistivity of the membrane decreased substantially with increasing drug concentration. Capacitance changes to the bilayer in most cases were insignificant. Using a Langmuir-Freundlich model to fit the EIS data, we propose Rsat as an empirical value that reflects permeation. Overall, the data indicate that Ibu, Levo, and Pef adsorb at the interface of the lipid membrane but Dic and Rif interact strongly, permeating the membrane core modifying the water/ion permeability of the bilayer structure. These observations are discussed in the context of previously reported data on drug permeability and log P.

Abstract
OBJECTIVES The aim of this study was to report on a half-day multi-stakeholder symposium on community treatment orders (CTOs) hosted by the Melbourne Social Equity Institute (MSEI), which identified research gaps and opportunities, and produced an agreed agenda for future CTO research. METHODS The MSEI convened a symposium for 22 experts in CTO research to discuss research priorities in this field in Australasia. An independent moderator elicited views and recommendations and produced a report detailing possible research projects. RESULTS Research on CTOs is contentious and there is a need to gather and examine information regarding both their use and utility. Due to the complexities involved, it was agreed that research should be undertaken in partnership with persons with had lived experience of mental health problems, clinicians, policymakers and other interdisciplinary stakeholders. Five key areas for future investigation were identified. CONCLUSIONS The issues and recommendations arising from the symposium should shape the scope, nature and conduct of future research directions in the field.

Abstract
When people with dementia are hospitalised, their capacity to communicate with the staff may be limited, compounding risks of distress and other adverse outcomes. Opportunities for carers to share relevant information to inform appropriate person-centred care are also limited. This four-phase mixed methods study aimed to develop an evidence-based family carer–staff communication form, the Focus on the Person form, to address this concern. In Phase I, a literature review plus consultation with clinicians and carers informed form development. In Phase II, the professionally formatted form was piloted by 31 family carers, who were then interviewed about their experiences. These data, combined with data from 30 hospital staff members who participated in Phase III focus groups, led to final, Phase IV, refinements of the form. The form now provides an opportunity for families to inform the person-centred care of people with dementia in hospital, potentially improving outcomes for this vulnerable group.

Abstract
BackgroundAlthough current best practice recommendations contribute to falls prevention in hospital, falls and injury rates remain high. There is a need to explore new interventions to reduce falls rates, especially in geriatric and general medical wards where older patients and those with cognitive impairment are managed.Design and methodsA three-cluster stepped wedge pragmatic trial, with an embedded qualitative process, of the Ambient Intelligent Geriatric Management (AmbIGeM) system (wearable sensor device to alert staff of patients undertaking at-risk activities), for preventing falls in older patients compared with standard care. The trial will occur on three acute/subacute wards in two hospitals in Adelaide and Perth, Australia.ParticipantsPatients aged >65 years admitted to study wards. A waiver (Perth) and opt-out of consent (Adelaide) was obtained for this study. Patients requiring palliative care will be excluded.OutcomesThe primary outcome is falls rate; secondary outcome measures are: (1) proportion of participants falling; (2) rate of injurious inpatient falls/1000 participant bed-days; (3) acceptability and safety of the interventions from patients and clinical staff perspectives; and (4) hospital costs, mortality and use of residential care to 3 months postdischarge.DiscussionThis study investigates a novel technological approach to preventing falls in hospitalised older people. We hypothesise that the AmbIGeM intervention will reduce falls and injury rates, with an economic benefit attributable to the intervention. If successful, the AmbIGeM system will be a useful addition to falls prevention in hospital wards with high proportions of older people and people with cognitive impairment.Trial registration numberAustralian and New Zealand Clinical Trial Registry: ACTRN 12617000981325; Pre-results.

Abstract
A novel and versatile approach to electrichemically triggering the release of a reagent, β-cyclodextrin (β-CD), selectively to the proximal leaflet of a supported lipid bilayer is described. Selective delivery is achieved by creating a spanning lipid bilayer across a microcavity array and exploiting the irreversible redox disassembly of the host-guest complex formed between thiolated ferrocene (Fc) and β-cyclodextrin (β-CD) in the presence of chloride. Self-assembled monolayers of the ferrocene-alkanethiols were formed regioselectively on the interior surface of highly ordered 2.8 μm cavities while the exterior top surface of the array was blocked with a monolayer of mercaptoethanol. The Fc monolayers were complexed with β-CD or β-CD-conjugated to streptavidin (β-CD-SA). Phospholipid bilayers were then assembled across the array via combined Langmuir-Blodgett/vesicle fusion leading to a spanning bilayer suspended across the aqueous filled microcavities. Upon application of a positive potential, ferrocene is oxidized to ferrocinium cation, disrupting the inclusion complex and leading to the release of the β-CD into the microcavity solution where it diffuses to the lower leaflet of the suspended bilayer. Disassembly of the supramolecular complex within the cavities and binding of the β-CD-SA to a biotinylated bilayer was followed by voltammetry and impedance spectroscopy where it caused a large increase in membrane resistance. For unmodified β-CD, the extraction of cholesterol from a cholesterol containing bilayer was evident in a decrease in the bilayer resistance. For the first time, this direct approach to targeted delivery of a reagent to the proximal layer of a lipid bilayer offers the potential to build models of bidirectional signaling (inside-out vs outside-in) in cell membrane model systems.

Abstract
Face detection, the perceptual capacity to identify a visual stimulus as a face before probing deeper into specific attributes (such as its identity or emotion), is essential for social functioning. Despite the importance of this functional capacity, face detection and its underlying brain mechanisms are not well understood. This study evaluated the roles that the cortical face processing system, which is identified largely through studying other aspects of face perception, play in face detection. Specifically, we used functional magnetic resonance imaging (fMRI) to examine the activations of the fusifom face area (FFA), occipital face area (OFA) and superior temporal sulcus (STS) when face detection was isolated from other aspects of face perception and when face detection was perceptually-equated across individual human participants (n=20). During face detection, FFA and OFA were significantly activated, even for stimuli presented at perceptual-threshold levels, whereas STS was not. During tree detection, however, FFA and OFA were responsive only for highly salient (i.e., high contrast) stimuli. Moreover, activation of FFA during face detection predicted a significant portion of the perceptual performance levels that were determined psychophysically for each participant. This pattern of result indicates that FFA and OFA have a greater sensitivity to face detection signals and selectively support the initial process of face vs. non-face object perception.

Abstract
BACKGROUND Face detection, an ability to identify a visual stimulus as a face, is impaired in patients with schizophrenia. It is unclear whether impaired face processing in this psychiatric disorder results from face-specific domains or stems from more basic visual domains. In this study, we examined cortical face-sensitive N170 response in schizophrenia, taking into account deficient basic visual contrast processing. METHODS We equalized visual contrast signals among patients (n=20) and controls (n=20) and between face and tree images, based on their individual perceptual capacities (determined using psychophysical methods). We measured N170, a putative temporal marker of face processing, during face detection and tree detection. RESULTS In controls, N170 amplitudes were significantly greater for faces than trees across all three visual contrast levels tested (perceptual threshold, two times perceptual threshold and 100%). In patients, however, N170 amplitudes did not differ between faces and trees, indicating diminished face selectivity (indexed by the differential responses to face vs. tree). CONCLUSION These results indicate a lack of face-selectivity in temporal responses of brain machinery putatively responsible for face processing in schizophrenia. This neuroimaging finding suggests that face-specific processing is compromised in this psychiatric disorder.

Abstract
Facial emotion perception impairment in schizophrenia is currently viewed as abnormal affective processing. Facial emotion perception also relies on visual processing. Yet, visual cortical processing of facial emotion is not well understood in this disorder. We measured perceptual thresholds for detecting facial fear and happiness in patients (n=23) and controls (n=23), and adjusted emotion intensity of facial stimuli (via morphing between images of neutral and emotive expressions) for each subject. We then evaluated activations of the visual cortex and amygdala during the performance of perceptually-equated facial emotion detection tasks. Patients had significantly lower fear- and happiness-induced activations in the visual cortex and amygdala. Activations between the visual cortex and amygdala were largely correlated, but the correlations in patients occurred abnormally early in response time course during fear perception. In schizophrenia, visual processing of facial emotion is deficient and visual and affective processing of negative facial emotion may be prematurely associated.

Abstract
PURPOSE Oesophageal adenocarcinoma is an exemplar model of obesity-associated cancer. Locally advanced disease is treated with neoadjuvant chemoradiotherapy, and survival rates are highest in patients demonstrating a pathological response following neoadjuvant therapy. Given that 55 % of oesophageal adenocarcinoma patients are obese, uncovering the effect of adipose tissue on radioresponse is clinically relevant. This study investigates if adipose tissue activates genomic instability events in radioresponsive (OE33P) and radioresistant (OE33R) oesophageal cancer cell lines and tumour samples. METHODS OE33R and OE33P were cultured with adipose-conditioned media derived from oesophageal adenocarcinoma patients (n = 10). Anaphase bridges, a marker of genomic instability, were enumerated in both cell lines following treatment with adipose media, and normalised to cell number. Genomic instability is regulated by the spindle assembly complex. Expression of two spindle assembly complex genes (MAD2L2, BUB1B) was assessed using qPCR, and validated in patient tumour specimens from viscerally obese (n = 46) and nonobese patients (n = 41). RESULTS Adipose-conditioned media increased anaphase bridging in OE33R (p < 0.0001), with a threefold increase in OE33R compared to OE33P (p < 0.01). Levels of anaphase bridges in OE33R cells correlated with visceral obesity status as measured by waist circumference (R = 0.709, p = 0.03) and visceral fat area (R = 0.794, p = 0.006). Adipose tissue altered expression of MAD2L2 in vitro. In vivo, MAD2L2 expression was higher in viscerally obese oesophageal adenocarcinoma patients compared with nonobese patients (p < 0.05). CONCLUSIONS Anaphase bridge levels are influenced by obesity and radiosensitivity status in oesophageal adenocarcinoma. Furthermore, visceral adipose-conditioned media stimulates dysregulation of the spindle assembly complex in oesophageal adenocarcinoma patients.

Abstract
BACKGROUND Presentations to hospital of older people receiving family care at home incur substantial costs for patients, families, and the health care system, yet there can be positive carer outcomes when systematically assessing/addressing their support needs, and reductions in older people's returns to hospital attributed to appropriate discharge planning. This study will trial the Further Enabling Care at Home program, a 2-week telephone outreach initiative for family carers of older people returning home from hospital. Hypotheses are that the program will (a) better prepare families to sustain their caregiving role and (b) reduce patients' re-presentations/readmissions to hospital, and/or their length of stay; also that reduced health system costs attributable to the program will outweigh costs of its implementation. METHODS/DESIGN In this randomised controlled trial, family carers of older patients aged 70+ discharged from a Medical Assessment Unit in a Western Australian tertiary hospital, plus the patients themselves, will be recruited at discharge (N = 180 dyads). Carers will be randomly assigned (block allocation, assessors blinded) to receive usual care (control) or the new program (intervention). The primary outcome is the carer's self-reported preparedness for caregiving (Preparedness for Caregiving Scale administered within 4 days of discharge, 2-3 weeks post-discharge, 6 weeks post-discharge). To detect a clinically meaningful change of two points with 80 % power, 126 carers need to complete the study. Patients' returns to hospital and subsequent length of stay will be ascertained for a minimum of 3 months after the index admission. Regression analyses will be used to determine differences in carer and patient outcomes over time associated with the group (intervention or control). Data will be analysed using an Intention to Treat approach. A qualitative exploration will examine patients' and their family carers' experiences of the new program (interviews) and explore the hospital staff's perceptions (focus groups). Process evaluation will identify barriers to, and facilitators of, program implementation. A comprehensive economic evaluation will determine cost consequences. DISCUSSION This study investigates a novel approach to identifying and addressing family carers' needs following discharge from hospital of the older person receiving care. If successful, the program has potential to be incorporated into routine post-discharge support. TRIAL REGISTRATION Australian and New Zealand Clinical Trial Registry: ACTRN12614001174673 .

Abstract
This work demonstrates resolution enhancement of a quadrupole mass filter (QMF) under the influence of a static magnetic field. Generally, QMF resolution can be improved by increasing the number of rf cycles an ion experiences when passing through the mass filter. In order to improve the resolution, the dimensions of the QMF or the operating parameters need to be changed. However, geometric modifications to improve performance increase the manufacturing cost and usually the size of the instrument. By applying a magnetic field, a low-cost, small footprint instrument with reduced power requirements can be realized. Significant improvement in QMF resolution was observed experimentally for certain magnetic field conditions, and these have been explained in terms of our theoretical model developed at the University of Liverpool. This model is capable of accurate simulation of spectra allowing the user to specify different values of mass spectrometer dimensions and applied input signals. The model predicts enhanced instrument resolution R>26,000 for a CO2 and N2 mixture with a 200-mm long mass filter operating in stability zone 3 via application of an axial magnetic field.

Abstract
BACKGROUND Delirium is common in older patients. Little is known of support needs of families of older hospital patients with delirium. AIMS AND OBJECTIVES To inform nursing practice, we sought to describe families' experiences, understanding of delirium and delirium care, and support needs. DESIGN Descriptive mixed methods. METHODS Review of questionnaire items used with families of people with terminal delirium informed development of a new questionnaire to evaluate the support needs in our study population. In a tertiary hospital delirium unit, we recruited 17 family carers of older patients with (non-terminal) delirium to respond to this questionnaire. Twelve participants (11 female) also took part in interviews addressing the study's aims. Descriptive statistics were calculated and thematic analysis was undertaken. RESULTS From the survey, key family issues included distress about the patient's condition, worries about future care, and a need for more information about how the patient might feel and how families could support the patient. Themes from interviews included The admission experience, Worries and concerns, Feeling supported, and The discharge experience. Limited understanding of delirium underpinned all themes. Families experienced shock and sadness at the change in the patient; they were reassured by the specialist care but needed more information about delirium, its effects and outcomes, and how they could help with care. Meeting long-term postdischarge needs was a key concern. CONCLUSIONS In this study, families with a hospitalised older relative who had delirium described a distressing experience and needs for informational support. Further research is needed outside of delirium-specific units and in samples including a greater proportion of male relatives. IMPLICATIONS FOR PRACTICE Nurses should work within the interdisciplinary team to ensure a planned, sensitive and timely approach to informing the patient's family about delirium and its implications for their relative, recognising the family carer's role and likely distress.

Abstract
In Australia, many people ageing in their own homes are becoming increasingly frail and unwell, approaching the end of life. A palliative approach, which adheres to palliative care principles, is often appropriate. These principles provide a framework for proactive and holistic care in which quality of life and of dying is prioritised, as is support for families. A palliative approach can be delivered by the general practitioner working with the community aged care team, in collaboration with family carers. Support from specialist palliative care services is available if necessary.The Guidelines for a Palliative Approach for Aged Care in the Community Setting were published by the Australian Government Department of Health and Ageing to inform practice in this area. There are three resource documents. The main document provides practical evidence based guidelines, good practice points, tools, and links to resources. This document is written for general practitioners, nurses, social workers, therapists, pastoral care workers, and other health professionals and responded to needs identified during national consultation. Evidence based guidelines were underpinned by systematic reviews of the research literature. Good practice points were developed from literature reviews and expert opinion. Two 'plain English' booklets were developed in a process involving consumer consultation; one is for older people and their families, the other for care workers.The resources are intended to facilitate home care that acknowledges and plans for the client's deteriorating functional trajectory and inevitable death. At a time when hospitals and residential aged care facilities are under enormous pressure as the population ages, such a planned approach makes sense for the health system as a whole. The approach also makes sense for older people who wish to die in their own homes. Family needs are recognised and addressed. Unnecessary hospitalisations or residential placements and clinically futile interventions are also minimised.

Abstract
The gastrointestinal lumen is directly exposed to dietary contaminants, including patulin, a mycotoxin produced by moulds. Patulin is known to increase permeability across intestinal Caco-2 monolayers. This study aimed to determine the effect of patulin on permeability, ion transport and morphology in isolated rat colonic mucosae. Mucosal sheets were mounted in Ussing chambers and voltage clamped. Apical addition of patulin (100-500 μM) rapidly reduced transepithelial electrical resistance (TEER) and increased permeability to [(14)C] mannitol (2.9-fold). Patulin also inhibited carbachol-induced electrogenic chloride secretion and histological evidence of mucosal damage was observed. To examine potential mechanisms of action of patulin on colonic epithelial cells, high-content analysis of Caco-2 cells was performed and this novel, quantitative fluorescence-based approach confirmed its cytotoxic effects. With regard to time course, the cytotoxicity determined by high content analysis took longer than the almost immediate reduction of electrical resistance in isolated mucosal sheets. These data indicate patulin is not only cytotoxic to enterocytes but also has the capacity to directly alter permeability and ion transport in intact intestinal mucosae. These data corroborate and extend findings in intestinal cell culture monolayers, and further suggest that safety limits on consumption of patulin may be warranted.
