Abstract
Cranberries are rich in polyphenols, have a high antioxidant capacity, and may protect against exercise-induced free radical production. Mitochondria are known producers of free radical in skeletal muscle, and preventing overproduction of radicals may be a viable approach to improve muscle health. This stud aimed to investigate the effect of a polyphenol-rich cranberry extract on muscle oxidative capacity and oxygenation metrics in healthy active adults. 17 participants (9 males, 8 females) were tested at: i) baseline, ii) 2 hours following an acute CE dose (0.7 g/kg of body mass), and iii) after 4 weeks of daily supplement consumption (0.3 g/kg of body mass). At each time point, muscle oxygen capacity was determined using near-infrared spectroscopy to measure the recovery kinetics of muscle oxygen consumption following a 15-20 s contraction of the vastus lateralis. Cranberry supplementation over 28 days significantly improved muscle oxygen capacity (k-constant, 2.8 ± 1.8 vs. 3.9 ± 2.2; p = 0.02). This was supported by a greater rate of oxygen depletion during a sustained cuff occlusion (-0.04 ± 0.02 vs. -0.07 ± 0.03; p = 0.02). Resting muscle oxygen consumption was not affected by cranberry consumption. Our results suggest that cranberry supplementation may play a role in improving mitochondrial health, which could lead to better muscle oxygen capacity in healthy active adult populations. The study protocol was registered with ClinicalTrials.gov (#NCT06186297).

Abstract
BACKGROUND People living with cardiac and respiratory disease require improved post-hospital support that is readily available and efficient. OBJECTIVES To 1) test the effectiveness of an automated, semi-personalised text message support program on clinical and lifestyle outcomes amongst people attending cardiac and pulmonary rehabilitation. Also, 2) to evaluate the program's acceptability and utility using patient-reported outcome and experience measures. METHODS Multicentre randomised controlled trial (3:1, intervention:control) amongst cardiac and pulmonary rehabilitation attendees. Control received usual care (no message program). Intervention also received a 6-month text message lifestyle and support program. Primary outcome was 6-minute walk distance (6MWD). Secondary outcomes included clinical measures, lifestyle, patient-reported outcome and experience measures, medication adherence and rehabilitation attendance. RESULTS A total of 316 participants were recruited. They had a mean age of 66.7 (SD 10.1) years. Sixty percent were male (190/316) and 156 were cardiac rehabilitation participants. The cohort's mean baseline 6MWD was higher in the intervention than the control group. At 6 months, 6MWD improved in both groups; it was significantly greater amongst intervention than control participants (unadjusted mean difference of 43.4 m, 95 % CI 4.3 to 82.4; P = 0.0296). After adjustment for baseline values, there was no significant difference between intervention and control groups for 6MWD (adjusted mean difference 2.2 m, -21.2 to 25.6; P = 0·85), medication adherence, or cardiovascular risk factors. At 6-month follow-up, intervention participants reported significantly lower depression scores (adjusted mean difference -1.3, 95 % CI -2.2 to -0.3; P = 0.0124) and CAT scores (adjusted mean difference -3.9, 95 % CI -6.6 to -1.3; P = 0.0038), and significantly lower anxiety (adjusted mean difference -1.1, 95 %CI -2.1 to 0; P = 0.0456). Most participants (86 %) read most of their messages and strongly/agreed that the intervention was easy to understand (99 %) and useful (86 %). CONCLUSIONS An educational and supportive text message program for cardiac and pulmonary rehabilitation attendees improved anxiety and depression plus program attendance. The program was acceptable to, and useful for, participants and would be suitable for implementation alongside rehabilitation programs. TRIAL REGISTRATION NUMBER ACTRN12616001167459.

Abstract
INTRODUCTION Recent estimations have projected a threefold increase in dementia prevalence in Aotearoa New Zealand (NZ) by 2050, particularly in Maori and Pacific peoples. However, to date, there are no national data on dementia prevalence, and overseas data are used to estimate the NZ dementia statistics. The aim of this feasibility study was to prepare the groundwork for the first full-scale NZ dementia prevalence study that is representative of Māori, European, Pacific and Asian peoples living in NZ. METHODS The main feasibility issues were: (i) Sampling to ensure adequate community representation from the included ethnic groups, (ii) Preparing a workforce to conduct the fieldwork and developing quality control, (iii) Raising awareness of the study in the communities (iv) Maximizing recruitment by door-knocking, (v) Retaining those we have recruited to the study and (vi) Acceptability of study recruitment and assessment using adapted versions of the 10/66 dementia protocol in different ethnic groups living in South Auckland. RESULTS We found that a probability sampling strategy using NZ Census data was reasonably accurate and all ethnic groups were sampled effectively. We demonstrated that we were able to train up a multi-ethnic workforce consisting of lay interviewers who were able to administer the 10/66 dementia protocol in community settings. The response rate (224/297, 75.5%) at the door-knocking stage was good but attrition at subsequent stages was high and only 75/297 (25.2%) received the full interview. CONCLUSIONS Our study showed that it would be feasible to conduct a population-based dementia prevalence study using the 10/66 dementia protocol in Māori, European and Asian communities living in NZ, utilizing a qualified, skilled research team representative of the families participating in the study. The study has demonstrated that for recruitment and interviewing in Pacific communities a different but culturally appropriate approach is required.

Abstract
PURPOSE Cranberries have the highest polyphenol and antioxidant capacity among fruits and vegetables and may protect against exercise-induced free radical production, consequently improving performance. This study aimed to investigate the effect of polyphenol-rich cranberry extract (CE) on time-trial performance and lactate response following exercise. METHODS A total of 14 trained runners were tested at i) baseline, ii) 2 h following an acute CE dose (0.7 g/kg of body mass), and iii) 4 weeks after daily supplement consumption (0.3 g/kg of body mass). At each time point, runners performed a 1500-m race followed by a 400-m race where the live vastus lateralis oxygenation changes were determined by near-infrared spectroscopy and blood lactate was measured at rest and 1 and 3 min after each trial. The Shapiro-Wilk test and repeated-measures analysis of variance were used to establish significance (P <0.05). RESULTS Cranberry supplementation over 28 d improved aerobic performance during the 1500-m time trial, whereas the acute dose had no effect. More specifically, muscle reoxygenation rates were significantly faster after 28 d compared to baseline (P = 0.04; η² = 0.29), and a trend towards slower deoxygenation rate was observed (P = 0.13; η² = 0.20). Chronic CE consumption also buffered the post-exercise lactate response for the 400-m race (P = 0.01; η² = 0.27), while no effects were seen for the longer race. CONCLUSION Our results suggest that cranberry supplementation may have ergogenic effects, as it improves physiological markers of performance during short- and long-distance running.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD) is a progressive disease resulting in a range of symptoms including breathlessness. "Symptom burden" describes the severity and impact of multiple symptoms in an individual and is best quantified using validated symptom instruments but is not routinely measured in clinical practice. Therefore, we wanted to assess overall symptom burden in patients with moderate-to-severe COPD and find associated independent predictors. Patients and methods A single-centre cross-sectional study of patients with COPD who attended the Westmead Breathlessness Service between March 2017 and May 2022 was conducted. We obtained baseline demographic data, lung function, assessed quality of life (CAT), anxiety/depression (HADS), and measured symptom burden (CMSAS). We compared variables between men and women using unpaired t tests or Mann-Whitney tests for continuous variables, and Fisher's exact tests for categorical variables. We used multiple regression to look for independent predictors of overall symptom burden. Data were analysed using Stata/IC 15.1. Results Eighty-nine patients with COPD, mean age 72.6 years, 55% male, mean FEV1 32% predicted, reported an average of 8.9 symptoms including 6.9 physical and 1.6 psychological symptoms. The most common physical symptoms were shortness of breath (100%) and lack of energy (80%), and the most common psychological symptoms were worrying (65%) and feeling anxious (61%). Median CMSAS total score was higher in women than men (1.34 versus 1.04, respectively; p=0.03) with more women experiencing nervousness (p=0.011) and anxiety (p=0.005). Female sex (p=0.003), HADS-Anxiety (p=0.0001), and HADS-Depression (p=0.0001) were independently associated with total CMSAS score in a multiple linear regression model and explained 63% of total CMSAS variability. Conclusion Very high physical and psychological symptom burden exists among patients with severe COPD. Anxiety, depression, and female sex were independently associated with increasing symptom burden. Identifying and understanding sex differences for COPD symptoms, and interventions targeting anxiety and depression may help to reduce overall symptom burden within this population.

Abstract
OBJECTIVE The study aimed to identify, appraise and update evidence on the association between cold temperatures (i.e. <18°C) within homes (i.e. dwellings) and health and well-being outcomes. STUDY DESIGN This study was a systematic review. METHODS Seven databases (MEDLINE, Embase, Cochrane Database of Systematic Reviews, CINAHL, APA PsycInfo, Applied Social Sciences Index and Abstracts, Coronavirus Research Database) were searched for studies published between 2014 and 2022, which explored the association between cold indoor temperatures and health and well-being outcomes. Studies were limited to those conducted in temperate and colder climates due to the increased risk of morbidity and mortality during winter in those climatic zones. Studies were independently quality assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. RESULTS Of 1209 studies, 20 were included for review. Study outcomes included cardiovascular (blood pressure, electrocardiogram abnormalities, blood platelet count), respiratory (chronic obstructive pulmonary disease symptoms, respiratory viral infection), sleep, physical performance and general health. Seventeen studies found exposure to cold indoor temperatures was associated with negative effects on health outcomes studied. Older individuals and those with chronic health problems were found to be more vulnerable to negative health outcomes. CONCLUSION Evidence suggests that indoor temperatures <18°C are associated with negative health effects. However, the evidence is insufficient to allow clear conclusions regarding outcomes from specific temperature thresholds for different population groups. Significant gaps in the current evidence base are identified, including research on the impacts of cold indoor temperatures on mental health and well-being, studies involving young children, and the long-term health effects of cold indoor temperatures.

Abstract
PURPOSE/OBJECTIVE(S) Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) shows improved sensitivity and specificity for detection of locoregional and distant metastatic prostate cancer (PCa) compared to conventional imaging, especially at lower PSA levels as is often the case in the biochemically recurrent (BCR), post radical prostatectomy (RP) setting. Providers are now utilizing PSMA PET findings to guide their salvage radiotherapy (sRT) treatment fields and doses, although it is not well understood how PSMA PET guided sRT impacts patient outcomes. MATERIALS/METHODS This was a post-hoc analysis of 5 prospective studies of PSMA PET conducted at UCLA from 2016 to 2021 that included patients with recurrent PCa following RP. Patients were included in this retrospective study if they initiated sRT within 3 months of PSMA PET, had at least 12 months of follow up after sRT completion, had available sRT treatment details, and did not have distant metastases (DM) by conventional imaging on upfront staging. Patients treated with palliative RT were excluded. BCR following sRT was defined as an increase in PSA of 0.2 ng/ml above the post sRT nadir. Metastasis directed therapy (MDT) was defined as sRT to all PSMA+ N1 and M1 lesions. Baseline patient demographics, PSMA PET findings, sRT & ADT treatment details, and patient outcome data were collected. RESULTS A total of 176 patients were included in this study. Median time between RP and PSMA PET was 38 months (range 1-329). Median PSA at the time of the PSMA PET was 0.625 ng/mL (range 0.063-35). PSMA PET was positive in 128 patients (73%): 21 (12%) miT+N0M0, 55 (31%) miTxN1M0 and 52 (30%) miTxNxM1 with 19 (11%) miTxNxM1a, 31 (18%) miTxNxM1b, and 2 (1%) miTxNxM1c. Median number of lesions seen on positive PSMA scans was 1 (range 1-8). 39 (22%) patients were subsequently treated with sRT to the prostate bed (PB) only, 59 (34%) to PB + pelvic lymph nodes (PLNs), 33 (19%) to PLNs only, 7 (4%) to PB + PLNs + DM, 7 (4%) to PLNs + DM, and 31 (18%) to DM only. 59 (34%) patients were treated with concurrent ADT at a median duration of 6 months (range 1-39). At a median follow-up of 32 months (range 12-70) after sRT, 80 patients (45%) did not develop BCR or imaging relapse (IR) following sRT, 24 patients (14%) developed BCR but not IR, 1 patient (<1%) developed IR only, and 70 patients (40%) developed both BCR and IR. The median time to BCR and IR following sRT was 15 months (range 1-48) and 19 months (range 6-61), respectively. 1 year post sRT biochemical recurrence free survival was 77%. Of the 83 patients treated with MDT, 32 (39%) did not develop subsequent disease relapse. CONCLUSION This post hoc analysis assessed the outcomes of 176 patients treated with PSMA PET guided salvage RT, proving it to be an effective method for treating both pelvic and extrapelvic recurrent PCa. Further investigation is needed to assess the full extent of patient outcomes in this population.

Abstract
Objectives Anticoagulants and antiplatelet (ACAP) agents are increasingly and frequently used, especially in the elderly. The present study was carried out to assess the prevalence of delayed traumatic intracranial hemorrhage (dtICH) after a normal result on an initial head computed tomography (CT) in adults who were taking ACAP medication. Materials and Methods The present retrospective included all adult patients who arrived in the emergency department between January 2017 and January 2021 with a history of fall from the patient's own height, while being on ACAP medication with an isolated head injury. The Institutional Review Board approved the study with a waiver of consent. The primary outcome measures were prevalence of dtICH in patients who had initial normal CT scan brain and were on ACAP medication. Results There were 2137 patients on ACAP medication, of which 1062 were male, and 1075 were of the female gender. The mean age of the patients was 82.1 years. About 8.2% had positive first CT scans (176/2137), while 0.023 (27/1149) had dtICH. The most common positive finding on the CT scan was subarachnoid hemorrhage followed by subdural hemorrhage. Male gender positively correlated with increased risk for first CT being positive (P = 0.033). Patient's with comorbidity of cirrhosis and chemotherapy had higher risk of dtICH (P = 0.47, 0.011). Conclusion There was a very low (0.023%) prevalence of dtICH. Dual therapy or Coumadin therapy made up the majority of tICH. Cirrhosis and chemotherapy were associated with the risk of a repeat CT scan being positive with an initial CT scan negative.

Abstract
INTRODUCTION Many studies of Black-White disparities in living donor kidney transplantation hypothesize that they were partially due to Black-White differences in candidate social network access to healthy, willing donors. This differential access hypothesis has not been tested using directly measured social network data. RESEARCH QUESTIONS Do black kidney transplant candidates have perceived lower social network access to health and/or willing living donors than white candidates? DESIGN A cross-sectional survey that measured the social network members was collected in 2015. Black-White differences in patient counts of perceived healthy and/or willing potential donors in social networks, and individual network members' probability of being perceived healthy and/or willing, were compared using logistic and negative binomial regression models. RESULTS The survey included 66 kidney transplant candidates reporting on 1474 social network members at a large Southeastern US transplant center in 2015. Black and White patients had similar access to perceived healthy, likely potential donors (86% vs 87% had 1 or more, P = .92; 5.91 vs 4.13 mean counts, P = .20) and perceived healthy, agreed potential donors (56% vs 48%, P = .54; 1.77 vs 1.74, P = .97). Black patients' network members were individually more likely to be perceived healthy and likely potential donors (26% vs 21%, P = .04), and White patients' network members were more likely to have agreed (13% vs 9%, P = .03), but these differences were statistically insignificant in demographically adjusted models. CONCLUSION Black and White transplant candidates perceived access to similar numbers of potential donors in their social networks. This result does not support the differential access hypothesis.

Abstract
Technology and digital platforms have become essential for people and communities to interact because of COVID-19. Despite its benefits, digital exclusion disproportionately affects Pacific communities living in New Zealand. This article provides insights into how Niue mamatua (older adults) used their gifted mobile phones and mobile data as part of a COVID-19 digital inclusion initiative. It begins with an overview of the digital inclusion needs of older adults, followed by a description of the digital vā (relational space) and negotiating a new way of maintaining connection in an online world. The tutala (a Niue method of conversation anchored on respect) with 12 mamatua highlighted the benefits, support factors, and challenges of how they were able to use their mobile phone. Importantly, mobile phones provided the necessary access and connectivity to interact in a digitally connected world, namely the digital vā, when in-person connections were disrupted because of COVID-19.

Abstract
Objective:
To estimate the association between educational assortative mating and cardiovascular outcomes among postmenopausal women in the Women’s Health Initiative study.
Background:
Between 1970 and 2015, the number of dual professional couples almost tripled. For instance, the likelihood of male attorneys marrying female lawyers and male doctors marrying female doctors has increased. Studies have proposed that educational assortative mating—people marry those with similar educational attainment--affects health disparities through increasing income inequality, creating differential levels of healthcare access, and based on the social cognitive theory, exchanging health knowledge and sharing healthy behaviors.
Methods:
We compared women living in three homogenous educational pairings; married women and spouses who both have 1) a high school degree or lower, 2) an associate or college degree, and 3) an MS, Ph.D., or professional degree. We used logistic regression models for prevalent outcomes (HTN, CHD, HF) at WHI baseline and Cox proportional hazard regression models for incident outcomes, all adjusted for age and total household income. To consider effect modification by membership in different racial or ethnic groups, we also conducted a stratified analysis.
Results:
We found significant associations between educational assortative mating and all cardiovascular outcomes within all groups of women. We found higher odds of prevalent cardiovascular outcomes ranging from 47 to 98 percent and a higher hazard of incident outcomes ranging from 24 to 56 percent. The strongest associations were found for prevalent and incident heart failure among Black women.
Conclusion:
This study provides evidence that educational assortative mating is likely a contributor to widening disparities in cardiovascular outcomes within and between racial groups of women.

Abstract
BACKGROUND Recent reports indicate that the contribution of deaths related to suicide and overdose are increasing, and may be the leading contributors to maternal mortality up to one year postpartum. OBJECTIVE This study aimed to provide a granular assessment of maternal deaths due to suicide or drug overdose in the state of Michigan from 2008 to 2018. STUDY DESIGN This retrospective study involved a secondary review of deceased patients' records from 2008 to 2018 stored at the Michigan Department of Health and Human Services through the Michigan Maternal Mortality Surveillance Program. Pregnancy-related and pregnancy-associated deaths were reviewed. A descriptive analysis of maternal characteristics and identified trends was presented in deidentified aggregate form. RESULTS There were 237 maternal deaths due to suicide or overdose from 2008 to 2018 included in the review. Overall, 70.9% had a documented psychiatric illness in their medical chart, with 48.1% having ≥2 psychiatric illnesses. However, only 34.5% (58/168) of these patients had documentation of taking psychotropic medication for their illness. Of those who died because of accidental or indeterminate substance overdose, 71.1% (138/194) had a known history of substance use disorder. Only 27.4% (43/157) of patients with a documented substance use disorder received medication-assisted treatment. Of those with substance overdose deaths, 42.9% had an opioid prescription, 44.3% had a benzodiazepine prescription, and 32.5% had a prescription for both. Prescription opioids were the most common substance found on postmortem toxicology report, and of these patients, 45.9% had a physician-prescribed opioid. CONCLUSION Most pregnant individuals had documented significant risk factors for mental illness or substance use disorder; however, very few had documented pharmacologic therapy for their psychiatric or addiction illness. There is an urgent need to implement effective multidisciplinary health system mitigation strategies that address pregnancy and its intersection with behavioral health.

Abstract
BACKGROUND Undernutrition, a common but treatable complication of chronic obstructive pulmonary disease (COPD), contributes to poor outcomes but is under-detected. Improved detection could prompt dietary intervention which may improve outcomes. We investigated whether adding a measure of muscle mass (fat-free mass index, FFMI) or a malnutrition screening tool (Mini Nutritional Assessment, MNA®) to the commonly used measure of body mass index (BMI), helps detect undernutrition in COPD. METHODS We conducted a retrospective chart review of 86 outpatients with COPD. Demographic and disease severity data were collected, and nutritional status assessed using BMI, FFMI and MNA®. RESULTS Patients comprised 55% males with median age 71.5 years, severe COPD (median FEV1 = 0.74 (30.5% predicted)) and high symptom impact (median COPD Assessment Test (CAT) = 23). Twenty-eight percent of patients had low BMI, 27% had low FFMI, 22% were MNA®-classified malnourished and 43% were MNA®-classified at risk of malnutrition. MNA® correlated moderately with BMI and classified 55% of patients with healthy/high BMI as either malnourished or at risk of malnutrition. FFMI and BMI correlated strongly, and low FFMI was present in 5% of patients with healthy/high BMI. The undernutrition measures also showed weak to moderate correlations with disease severity (spirometry data) and MNA® weakly correlated with symptom impact (CAT). CONCLUSION The MNA® identified more undernourished patients than FFMI or BMI. It also correlated with disease severity and broader symptom burden. The MNA® appears to be a simple tool for earlier detection of patients who may benefit from dietary intervention, potentially enhancing their quality of life.

Abstract
Glucocorticoids are regularly used as biomarkers of relative health for individuals and populations. Around the Western Antarctic Peninsula (WAP), baleen whales have and continue to experience threats, including commercial harvest, prey limitations and habitat change driven by rapid warming, and increased human presence via ecotourism. Here, we measured demographic variation and differences across the foraging season in blubber cortisol levels of humpback whales (Megaptera novaeangliae) over two years around the WAP. Cortisol concentrations were determined from 305 biopsy samples of unique individuals. We found no significant difference in the cortisol concentration between male and female whales. However, we observed significant differences across demographic groups of females and a significant decrease in the population across the feeding season. We also assessed whether COVID-19-related reductions in tourism in 2021 along the WAP correlated with lower cortisol levels across the population. The decline in vessel presence in 2021 was associated with a significant decrease in humpback whale blubber cortisol concentrations at the population level. Our findings provide critical contextual data on how these hormones vary naturally in a population over time, show direct associations between cortisol levels and human presence, and will enable comparisons among species experiencing different levels of human disturbance.

Abstract
BackgroundPatients with autoimmune inflammatory rheumatic diseases are susceptible to infections. This could be attributed to theimmunosuppressive effect of the underlying condition or the use of immunomodulatory medications. According to the Department of Health guidelines inthe UK and the European League Against Rheumatism (EULAR), patients who are immunosuppressed should be vaccinated against influenza and pneumococcal infection, as well as COVID-19 infection.ObjectivesOur aim was to explore the Pneumococcal, Influenza and COVID-19 vaccination uptake of our patients with different autoimmune inflammatory rheumatological conditions. In addition, to assess the side effects profile and the status of their underlying rheumatological diseases following COVID-19 vaccination.MethodsWe undertook a prospective audit of consecutive patients with regards to their vaccination update for influenza, pneumococcus, and COVID-19, utilizing a standard questionnaire and compared the results to our 2017 data.ResultsSome 81% of patients received the influenza vaccination (compared to 47% in 2017) representing a 172% improvement, p<0.001. Some 53% received the pneumococcus vaccination compared to 28% in 2017, indicating a 185% improvement, p=0.003. With regards to COVID-19 vaccination, 98/101(97%) of eligible patients received at least one dose and 66% received two doses. 47% received Astra Zeneca, 52% Pfizer and 1% unsure. 46% of patients mentioned, no one specifically discussed the COVID vaccine with them - got information via SMS/ from media, However, 37% of patients were informed by GP Doctor/ Nurse, 14% from the person giving the vaccine, and 7% from specialist hospital doctor. Safety concerns were indicated by all 3 patients who deferred vaccination.Most side-effects were observed following the first dose (74 patients) vs. the second dose (13 patients) and were mainly mild (66%), but also moderate (19%) and severe (15%). The sore arm was the commonest side-effect, whilst the majority of side-effects resolved within two days. Crucially, 28% reported a flare of the rheumatological condition following the vaccination. No patients receiving at least one dose were diagnosed with COVID-19 infection subsequently.ConclusionVaccination rates for influenza and pneumococcus have improved substantially since 2017, although the population with rheumatic diseases still has low uptake in pneumococcal vaccination. The COVID-19 vaccination uptake has been extremely high in this cohort.Disclosure of InterestsNone declared

Abstract
The IAEA fundamental safety objective is'to protect people and the environment from harmful effects of ionizing radiation'and this must be done 'without unduly limiting the operation of facilities or the conduct of activities that give rise to radiation risks', while ensuring that people and the environment, present and future are protected against radiation risks (IAEA 2006Fundamental Safety Principles, Safety FundamentalsNo. SF-1). In addition,'protective actions to reduce existing or unregulated radiation risks must be justified and optimized'(IAEA 2006Fundamental Safety Principles, Safety FundamentalsNo. SF-1). An international system of radiological protection can be applied such that processes, such as remediation, can be systematically undertaken to address the wide range of'existing exposure situations'present globally. In doing so, decisions made regarding actions undertaken can be demonstrated to be'justified'and'optimized'(i.e. balanced), such that the amount of effort should be commensurate with the risk (applying a'graded approach'). In addition, protection of people and the environment can be demonstrated by comparing the actual exposure to appropriate criteria over the lifetime of remediation. This paper provides an overview of the current IAEA safety standards on remediation of sites or areas contaminated with residual radioactive material within the international system of radiological protection and provides practical examples of their application through case studies considered in IAEA international model validation programs.

Abstract
BACKGROUND There is growing recognition that reproductive factors are associated with increased risk of future cardiovascular disease. Infertility has been less well studied, although emerging data support its association with increased risk of cardiovascular disease. Whether infertility is associated with future risk of heart failure (HF) is not known. OBJECTIVES This study sought to examine the development of HF and HF subtypes in women with and without history of infertility. METHODS We followed postmenopausal women from the Women's Health Initiative prospectively for the development of HF. Infertility was self-reported at study baseline. Multivariable cause-specific Cox models were used to evaluate the association of infertility with incident overall HF and HF subtypes (heart failure with preserved ejection fraction [HFpEF]: left ventricular ejection fraction of ≥50% vs heart failure with reduced ejection fraction [HFrEF]: left ventricular ejection fraction of <50%]). RESULTS Among 38,528 postmenopausal women (mean age: 63 ± 7 years), 5,399 (14%) participants reported a history of infertility. Over a median follow-up of 15 years, 2,373 developed incident HF, including 807 with HFrEF and 1,133 with HFpEF. Infertility was independently associated with future risk of overall HF (HR: 1.16; 95% CI: 1.04-1.30; P = 0.006). Notably, when examining HF subtypes, infertility was associated with future risk of HFpEF (HR: 1.27; 95% CI: 1.09-1.48; P = 0.002) but not HFrEF (HR: 0.97; 95% CI: 0.80-1.18). CONCLUSIONS Infertility was significantly associated with incident HF. This was driven by increased risk of HFpEF, but not HFrEF, and appeared independent of traditional cardiovascular risk factors and other infertility-related conditions. Future research should investigate mechanisms that underlie the link between infertility and HFpEF.

Implementing the battery-operated hand-held fan as an evidence-based, non-pharmacological intervention for chronic breathlessness in patients with chronic obstructive pulmonary disease (COPD): a qualitative study of the views of specialist respiratory clinicians.

Abstract
Introduction The battery-operated hand-held fan (‘fan’) is an inexpensive and portable non-pharmacological intervention for chronic breathlessness. Evidence from randomised controlled trials suggests the fan reduces breathlessness intensity and improves physical activity in patients with a range of advanced chronic conditions. Qualitative data from these trials suggests the fan may also reduce anxiety and improve daily functioning for many patients. This study aimed to explore barriers and facilitators to the fan’s implementation in specialist respiratory care as a non-pharmacological intervention for chronic breathlessness in patients with chronic obstructive pulmonary disease (COPD). Methods A qualitative approach was taken, using focus groups. Participants were clinicians from any discipline working in specialist respiratory care at two hospitals. Questions asked about current fan-related practice and perceptions regarding benefits, harms and mechanisms, and factors influencing its implementation. Analysis used a mixed inductive/deductive approach. Results Forty-nine participants from nursing (n = 30), medical (n = 13) and allied health (n = 6) disciplines participated across 9 focus groups. The most influential facilitator was a belief that the fan’s benefits outweighed disadvantages. Clinicians’ beliefs about the fan’s mechanisms determined which patient sub-groups they targeted, for example anxious or palliative/end-stage patients. Barriers to implementation included a lack of clarity about whose role it was to implement the fan, what advice to provide patients, and limited access to fans in hospitals. Few clinicians implemented the fan for acute-on-chronic breathlessness or in combination with other interventions. Conclusion Implementation of the fan in specialist respiratory care may require service- and clinician-level interventions to ensure it is routinely recommended as a first-line intervention for chronic breathlessness in patients for whom this symptom is of concern, regardless of COPD stage.

Abstract
Oxygen is a life-saving therapy but, when given inappropriately, may also be hazardous. Therefore, in the acute medical setting, oxygen should only be given as treatment for hypoxaemia and requires appropriate prescription, monitoring and review. This update to the Thoracic Society of Australia and New Zealand (TSANZ) guidance on acute oxygen therapy is a brief and practical resource for all healthcare workers involved with administering oxygen therapy to adults in the acute medical setting. It does not apply to intubated or paediatric patients. Recommendations are made in the following six clinical areas: assessment of hypoxaemia (including use of arterial blood gases); prescription of oxygen; peripheral oxygen saturation targets; delivery, including non-invasive ventilation and humidified high-flow nasal cannulae; the significance of high oxygen requirements; and acute hypercapnic respiratory failure. There are three sections which provide (1) a brief summary, (2) recommendations in detail with practice points and (3) a detailed explanation of the reasoning and evidence behind the recommendations. It is anticipated that these recommendations will be disseminated widely in structured programmes across Australia and New Zealand.

Abstract
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log10 increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence.

Abstract
This pilot study examined a novel technology-enhanced real-time action observation therapy (TERTAOT) of symmetrical bilateral movements in survivors of chronic stroke regardless of their ability to move their paretic limb(s). The TERTAOT used a Kinect XBox One to project mirror images of non-paretic limbs as participants performed symmetrical bilateral motor tasks involving whole-body movements in sitting or standing. The participants received eight weeks of treatment consisting of 30-minutes of conventional physical therapy (balance training, gait training, neuromuscular reeducation, and generalized strength training) and 30-minutes of the TERTAOT protocol per session (three sessions per week for a total of 24 sessions). Ten Meter Walk Test (10MWT), Five Times Sit-to-Stand (5TSTS), Timed Up and Go (TUG), Motor Activity Log - Quality of Movement (QOM) and Amount of Use (AOU) were administered at baseline (pretest), 4 weeks (posttest 1) and 8 weeks (posttest 2) post-TERTAOT, and 3 months after TERTAOT ended (retention). A General Linear Model Repeated Measures (parametric test) or the Friedman Test (non-parametric test) was used to compare outcomes across time points, depending on the normality of data distribution. Bonferroni post-hoc corrections were applied. Seventeen participants completed >80% of TERTAOT sessions without adverse events. The effect of time was significant for 10MWT (p = .001), 5TSTS (p = .001), TUG (p = .005), QOM (p = .001), and AOU (p = .017). TERTAOT may be feasible to be implemented in an outpatient setting. Improvements in functional outcomes including gait, balance, and use of upper limbs were observed after eight weeks of conventional therapy and TERTAOT protocol in survivors of chronic stroke.

Abstract
New treatments for bone diseases require testing in animal models before clinical translation, and the mouse tibia is among the most common models. In vivo micro-Computed Tomography (microCT)-based micro-Finite Element (microFE) models can be used for predicting the bone strength non-invasively, after proper validation against experimental data. Different modelling techniques can be used to estimate the bone properties, and the accuracy associated with each is unclear. The aim of this study was to evaluate the ability of different microCT-based microFE models to predict the mechanical properties of the mouse tibia under compressive load. Twenty tibiae were microCT scanned at 10.4 µm voxel size and subsequently compressed at 0.03 mm/s until failure. Stiffness and failure load were measured from the load-displacement curves. Different microFE models were generated from each microCT image, with hexahedral or tetrahedral mesh, and homogeneous or heterogeneous material properties. Prediction accuracy was comparable among models. The best correlations between experimental and predicted mechanical properties, as well as lower errors, were obtained for hexahedral models with homogeneous material properties. Experimental stiffness and predicted stiffness were reasonably well correlated (R2 = 0.53-0.65, average error of 13-17%). A lower correlation was found for failure load (R2 = 0.21-0.48, average error of 9-15%). Experimental and predicted mechanical properties normalized by the total bone mass were strongly correlated (R2 = 0.75-0.80 for stiffness, R2 = 0.55-0.81 for failure load). In conclusion, hexahedral models with homogeneous material properties based on in vivo microCT images were shown to best predict the mechanical properties of the mouse tibia.

Abstract
OBJECTIVES This study aimed to explore the degree to which non-pharmacological strategies for chronic breathlessness are sustained 6 months after completing a breathlessness service in patients with chronic obstructive pulmonary disease (COPD), and patient perceptions regarding the need for ongoing support. DESIGN A qualitative approach was taken using semistructured telephone interviews. Thematic analysis used an integrative approach. SETTING The Westmead Breathlessness Service (WBS) trains patients with COPD to self-manage chronic breathlessness over an 8-week programme with multidisciplinary input and home visits. PARTICIPANTS Patients with moderate to very severe COPD who had completed the WBS programme 6 months earlier. RESULTS Thirty-two participants were interviewed. One or more breathlessness self-management strategies were sustained by most participants, including breathing techniques (n=22; 69%), the hand-held fan (n=17; 53%), planning/pacing and exercise (n=14 for each; 44%) and strategic use of a four-wheeled walker (n=8; 25%). However, almost a third of participants appeared to be struggling psychologically, including some who had refused psychological intervention. A 'chaos narrative' appeared to be prevalent, and many participants had poor recall of the programme. CONCLUSIONS Self-management strategies taught by breathlessness services to patients with moderate to very severe COPD have potential to be sustained 6 months later. However, psychological coping may be more challenging to maintain. Research is needed on ways to improve resilience to set-backs and uptake of psychological interventions, as well as to understand and address the implications of poor recall for self-management. TRIAL REGISTRATION NUMBER ACTRN12617000499381.

Abstract
INTRODUCTION Aotearoa/New Zealand (NZ) is officially recognised as a bicultural country composed of Māori and non-Māori. Recent estimations have projected a threefold increase in dementia prevalence in NZ by 2050, with the greatest increase in non-NZ-Europeans. The NZ government will need to develop policies and plan services to meet the demands of the rapid rise in dementia cases. However, to date, there are no national data on dementia prevalence and overseas data are used to estimate the NZ dementia statistics. The overall aim of the Living with Dementia in Aotearoa study was to prepare the groundwork for a large full-scale NZ dementia prevalence study. METHODS AND ANALYSIS The study has two phases. In phase I, we will adapt and translate the 10/66 dementia assessment protocol to be administered in Māori, Samoan, Tongan and Fijian-Indian elders. The diagnostic accuracy of the adapted 10/66 protocol will be tested in older people from these ethnic backgrounds who were assessed for dementia at a local memory service. In phase II, we will address the feasibility issues of conducting a population-based prevalence study by applying the adapted 10/66 protocol in South Auckland and will include NZ-European, Māori, Samoan, Tongan, Chinese and Fijian-Indian participants. The feasibility issues to be explored are as follows: (1) how do we sample to ensure we get accurate community representation? (2) how do we prepare a workforce to conduct the fieldwork and develop quality control? (3) how do we raise awareness of the study in the community to maximise recruitment? (4) how do we conduct door knocking to maximise recruitment? (5) how do we retain those we have recruited to remain in the study? (6) what is the acceptability of study recruitment and the 10/66 assessment process in different ethnic groups? ETHICS AND DISSEMINATION The validity and feasibility studies were approved by the New Zealand Northern A Health and Disability Ethics Committee (numbers 17NTA234 and 18NTA176, respectively). The findings will be disseminated through peer-reviewed academic journals, national and international conferences, and public events. Data will be available on reasonable request from the corresponding author.

Abstract
Current therapeutic options with prokinetic agents for posttransplant gastroparesis are limited. Erythromycin is associated with adverse reactions, including corrected QT interval prolongation and cytochrome P450 3A4 isoenzyme inhibition. The use of erythromycin has been avoided in patients undergoing treatment with cyclosporine or tacrolimus because of significant fluctuations in therapeutic immunosuppression levels. We report herein the successful use of erythromycin after visceral transplant to treat delayed gastric emptying. Two patients were managed with oral erythromycin (initial dose of 750 mg/d divided into 3 doses) for gastroparesis after visceral transplant. Patient 1 was a woman aged 42 years with a history of chronic intestinal pseudo-obstruction syndrome who underwent isolated small bowel transplant with dual (gastric and duodenal) proximal allograft anastomosis. Posttransplant gastroparesis was initially managed with oral metoclopramide. The patient also required high doses of tacrolimus (36 mg/d) to maintain adequate immunosuppression levels. The decision was made to change metoclopramide to erythromycin, which significantly decreased the daily tacrolimus dose requirement (from 36 to 9 mg/d), with resolution of nausea and intermittent bloating symptoms. Patient 2 was a woman aged 35 years with ultra-short gut syndrome after extensive enterectomy due to intestinal volvulus who underwent uneventful combined intestinal and colon transplant. Conventional pharmacologic therapy for gastroparesis was initiated after surgery without success. Erythromycin was started 15 days posttransplant, with significant improvement in her symptoms, and discontinued 47 days post-transplant. To maintain therapeutic levels (8-10 mg/dL), daily tacrolimus dose was decreased 75.8% and 36.5% for patients 1 and 2, respectively. No significant side effects associated with erythromycin use were observed in either patient. Our findings here suggest that erythromycin may be safely used for gastroparesis after small bowel transplant. Close monitoring of immunosuppressive drug levels and dose adjustments of other medications affected by inhibition of cytochrome P450 3A4 are advised.

Abstract
IntroductionPsychiatric intensive care units (or PICU’s) emerged to manage high acuity patients outside the justice system. Studies have sought to better understand characteristics of those admitted to forensic or civilian PICU’s. Few, in contrast, have explored the frequency and contributors to readmission. The following study was conducted on Apsley unit, a Forensic PICU based in Melbourne, Australia, and seeks to understand the differences which would allow early identification of patients likely to require readmission and the provision of targeted interventions.ObjectivesExamine rates of and contributors to forensic PICU readmission over a 6-month period.MethodsA retrospective audit was conducted to collect clinical, problem behaviour (and strategies to manage), forensic history and demographic information for consecutively admitted patients to an 8-bed forensic PICU between March-September 2019.ResultsData analysis is ongoing. Interim analysis found that 96 patients were admitted during the 6-month study period: 74 (77.1%) had a single admission; 22 (22.9%) required readmission. Almost all were admitted from prison (96.9%), most had a psychosis diagnosis (80.2%) and substance abuse history (96.9%), and many had a personality disorder (24.0%) and history of adolescent antisocial behaviour (46.5%). Patients requiring readmission were significantly more likely to have been previously under compulsory mental health treatment (95.5% vs 75.3%, p=.039) and have a Positive Behaviour Support Plan developed during admission (85.7% vs 54.8%, p=.010).ConclusionsInterim analysis highlighted the multicomplexity for forensic PICU patients alongside the occurrence of problem behaviour during admission and history of compulsory treatment as indicators of increased risk for re-admission.

Abstract
BACKGROUND The cholesterol content of circulating triglyceride-rich lipoproteins is characterized as remnant cholesterol, although little is known about its role in the development of CVD outcomes, all-cause mortality, or transplant failure in kidney transplant recipients. Our primary aim was to investigate the prospective association of remnant cholesterol and the risk of CVD events in renal transplant recipients with secondary aims evaluating remnant cholesterol and renal graft failure and all-cause mortality among participants in the Folic Acid for Vascular Outcome Reduction in Transplantation (FAVORIT) trial. METHODS Among 4,110 enrolled participants, 98 were excluded for missing baseline remnant cholesterol levels and covariates. Non fasting remnant cholesterol levels were calculated based upon lipid profiles in 3,812 FAVORIT trial participants at randomization. Wilcoxon-type test for trend were used to compare baseline characteristics across remnant cholesterol quartiles. Cox proportional hazards regression was used to evaluate the association of baseline remnant cholesterol levels with time to primary and secondary study outcomes. RESULTS During a median follow-up of 4.0 years, we documented 548 CVD incident events, 343 transplant failures, 452 All-Cause deaths. When comparing highest quartile 4 to quartile 1, proportional hazards modeling revealed a significant increase in CVD risk (HR, 1.32; 95% CI, 1.04-1.67) and all-cause mortality risk (HR, 1.34; 95% CI, 1.01-1.69). A non-significant increase in transplant failure was seen as well (HR, 1.20; 95% CI, 0.87-1.64). CONCLUSION Remnant cholesterol is associated with CVD and all-cause mortality in long-term kidney transplant recipients KTRs. A randomized controlled clinical trial in KTRs that assesses the potential impact of remnant cholesterol-lowering therapy on these outcomes may be warranted.

Abstract
We performed a cross-sectional study within a specialised respiratory inpatient unit assessing 25 nurses' [85% female, 8.0 ± 7.9 (mean ± SD) years' experience in nursing] confidence in providing inhaler device education using a self-reported questionnaire, and their competency (% correct steps) in using eight different inhaler devices. Sixteen percent of participants were 'not confident' providing inhaler education, while 84% were 'moderately' or 'extremely' confident. The mean (±SD)% correct steps for all devices was 47 ± 17%. There was no correlation between % correct steps and nursing years (r = 0.21, p = 0.31), or 'confidence' with providing inhaler education (r = 0.02, p = 0.91) but % correct steps strongly correlated with number of individual device prescriptions within the hospital in the preceding year (r = 0.78, p = 0.039). Most respiratory nurses felt confident in teaching inhaler technique but their overall demonstrated ability to correctly use inhalers was poor, especially for less frequently prescribed devices within our hospital. Regular assessment and ongoing education on correct inhaler technique for respiratory nurses is necessary to optimise all device usage by nurses, irrespective of experience or confidence.

Abstract
BACKGROUND In Australia and other developed countries, chronic illness prevalence is increasing, as are costs of healthcare, particularly hospital-based care. Integrating healthcare and supporting illness management in the community can be a means of preventing illness, improving outcomes and reducing unnecessary hospitalisation. Western Sydney has high rates of diabetes, heart and respiratory diseases and the NSW State Ministry of Health funded a range of key strategies through the Western Sydney Integrated Care Program (WSICP) to integrate care across hospital and community settings for patients with these illnesses. Complementing our previously reported analysis related to specific WSICP strategies, this research provided information concerning overall experiences and perspectives of WSICP implementation and integrated care generally. METHODS We administered 125 in-depth interviews in two rounds over 12 months with 83 participants including patients and their carers, care facilitators, hospital specialists and nurses, allied health professionals, general practitioners and primary care nurses, and program managers. Half of the participants (n = 42) were interviewed twice. We conducted an inductive, thematic analysis on the interview transcripts. RESULTS Key themes related to the set-up and operationalising of WSICP; challenges encountered; and the added value of the program. Implementing WSICP was a large and time consuming undertaking but challenges including those with staffing and information technology were being addressed. The WSICP was considered valuable in reducing hospital admissions due to improved patient self-management and a focus on prevention, greater communication and collaboration between healthcare providers across health sectors and an increased capacity to manage chronic illness in the primary care setting. CONCLUSIONS Patients, carers and health providers experienced the WSICP as an innovative integrated care model and valued its patient-centred approach which was perceived to improve access to care, increase patient self-management and illness prevention, and reduce hospital admissions. Long-term sustainability of the WSICP will depend on retaining key staff, more effectively sharing information including across health sectors to support enhanced collaboration, and expanding the suite of activities into other illness areas and locations. Enhanced support for general practices to manage chronic illness in the community, in collaboration with hospital specialists is critical. Timely evaluation informs ongoing program implementation.

Abstract
The ability of Antarctic notothenioid fishes to mount a robust molecular response to hypoxia is largely unknown. The transcription factor, hypoxia-inducible factor-1 (HIF-1), a heterodimer of HIF-1α and HIF-1β subunits, is the master regulator of oxygen homeostasis in most metazoans. We sought to determine if, in the hearts of Antarctic notothenioids, HIF-1 is activated and functional in response to either an acute heat stress or hypoxia. The red-blooded Notothenia coriiceps and the hemoglobinless icefish, Chaenocephalus aceratus, were exposed to their critical thermal maximum (CTMAX) or hypoxia (5.0 ± 0.3 mg of O2 L-1) for 2 h. Additionally, N. coriiceps was exposed to 2.3 ± 0.3 mg of O2 L-1 for 12 h, and red-blooded Gobionotothen gibberifrons was exposed to both levels of hypoxia. Levels of HIF-1α were quantified in nuclei isolated from heart ventricles using western blotting. Transcript levels of genes involved in anaerobic metabolism, and known to be regulated by HIF-1, were quantified by real-time PCR, and lactate levels were measured in heart ventricles. Protein levels of HIF-1α increase in nuclei of hearts of N. coriiceps and C. aceratus in response to exposure to CTMAX and in hearts of N. coriiceps exposed to severe hypoxia, yet mRNA levels of anaerobic metabolic genes do not increase in any species, nor do lactate levels increase, suggesting that HIF-1 does not stimulate metabolic remodeling in hearts of notothenioids under these conditions. Together, these data suggest that Antarctic notothenioids may be vulnerable to hypoxic events, which are likely to increase with climate warming.
