Astrocyte-neuron lactate transport is required for long-term memory formation.

We report that, in the rat hippocampus, learning leads to a significant increase in extracellular lactate levels that derive from glycogen, an energy reserve selectively localized in astrocytes. Astrocytic glycogen breakdown and lactate release are essential for long-term but not short-term memory formation, and for the maintenance of long-term potentiation (LTP) of synaptic strength elicited in vivo. Disrupting the expression of the astrocytic lactate transporters monocarboxylate transporter 4 (MCT4) or MCT1 causes amnesia, which, like LTP impairment, is rescued by L-lactate but not equicaloric glucose. Disrupting the expression of the neuronal lactate transporter MCT2 also leads to amnesia that is unaffected by either L-lactate or glucose, suggesting that lactate import into neurons is necessary for long-term memory. Glycogenolysis and astrocytic lactate transporters are also critical for the induction of molecular changes required for memory formation, including the induction of phospho-CREB, Arc, and phospho-cofilin. We conclude that astrocyte-neuron lactate transport is required for long-term memory formation.

Anti-Vascular Endothelial Growth Factor Drugs Compared With Panretinal Photocoagulation for the Treatment of Proliferative Diabetic Retinopathy: A Cost-Effectiveness Analysis.

OBJECTIVES: This study aimed to evaluate the cost-effectiveness of anti-vascular endothelial growth factor drugs (anti-VEGFs) compared with panretinal photocoagulation (PRP) for treating proliferative diabetic retinopathy (PDR) in the United Kingdom. METHODS: A discrete event simulation model was developed, informed by individual participant data meta-analysis. The model captures treatment effects on best corrected visual acuity in both eyes, and the occurrence of diabetic macular edema and vitreous hemorrhage. The model also estimates the value of undertaking further research to resolve decision uncertainty. RESULTS: Anti-VEGFs are unlikely to generate clinically meaningful benefits over PRP. The model predicted anti-VEGFs be more costly and similarly effective as PRP, generating 0.029 fewer quality-adjusted life-years at an additional cost of £3688, with a net health benefit of -0.214 at a £20 000 willingness-to-pay threshold. Scenario analysis results suggest that only under very select conditions may anti-VEGFs offer potential for cost-effective treatment of PDR. The consequences of loss to follow-up were an important driver of model outcomes. CONCLUSIONS: Anti-VEGFs are unlikely to be a cost-effective treatment for early PDR compared with PRP. Anti-VEGFs are generally associated with higher costs and similar health outcomes across various scenarios. Although anti-VEGFs were associated with lower diabetic macular edema rates, the number of cases avoided is insufficient to offset the additional treatment costs. Key uncertainties relate to the long-term comparative effectiveness of anti-VEGFs, particularly considering the real-world rates and consequences of treatment nonadherence. Further research on long-term visual acuity and rates of vision-threatening complications may be beneficial in resolving uncertainties.

A Randomized Controlled Trial of a Behavioral Activation Intervention to Increase Engagement with Life and Well-Being in Older Adults.

INTRODUCTION: Engagement with life is central to aging well. There is currently a lack of flexible programs for promoting engagement that tailor to the unique interests, capacities, and life circumstances of individuals. We designed and evaluated a new program for promoting engagement with later life based on principles of behavioral activation. METHODS: A total of 135 adults aged 65 years and older who scored at or below the median on the Life Engagement Test were randomly assigned to either a 6-week behavioral activation program (n = 69) or a 6-week well-being program based on brief positive psychology interventions (the active control; n = 66). Participants completed assessments at baseline, 1-week follow-up, and 3-month follow-up. The primary outcome was engagement with life, and secondary outcome measures included social network characteristics, measures of mental health, well-being, and psychological and self-regulatory resources. RESULTS: Participants in both conditions showed improvements in engagement with life post-intervention that were sustained at 3 months. Post-intervention improvements in both conditions were observed across most secondary outcomes; however, for several outcomes, participants with more limited functional and cognitive resources benefitted from participation in the positive psychology (active control) condition, but not the treatment condition. CONCLUSION: Similar levels of improvement in engagement with life and well-being were evident for participants who completed a behavioral activation-focused intervention, compared with participants who completed a positive psychology-focused intervention. The positive psychology approach may confer greater benefits for emotional well-being among those with poorer functional and cognitive abilities.

An Autopsy Series of Seven Cases of VPS13A Disease (Chorea-Acanthocytosis).

BACKGROUND: Vacuolar protein sorting 13 homolog A (VPS13A) disease, historically known as chorea-acanthocytosis, is a rare neurodegenerative disorder caused by biallelic mutations in VPS13A, usually resulting in reduced or absent levels of its protein product, VPS13A. VPS13A localizes to contact sites between subcellular organelles, consistent with its recently identified role in lipid transfer between membranes. Mutations are associated with neuronal loss in the striatum, most prominently in the caudate nucleus, and associated marked astrogliosis. There are no other known disease-specific cellular changes (eg, protein aggregation), but autopsy reports to date have been limited, often lacking genetic or biochemical diagnostic confirmation. OBJECTIVE: The goal of this study was to characterize neuropathological findings in the brains of seven patients with VPS13A disease (chorea-acanthocytosis). METHODS: In this study, we collected brain tissues and clinical data from seven cases of VPS13A for neuropathological analysis. The clinical diagnosis was confirmed by the presence of VPS13A mutations and/or immunoblot showing the loss or reduction of VPS13A protein. Tissues underwent routine, special, and immunohistochemical staining focused on neurodegeneration. Electron microscopy was performed in one case. RESULTS: Gross examination showed severe striatal atrophy. Microscopically, there was neuronal loss and astrogliosis in affected regions. Luxol fast blue staining showed variable lipid accumulation with diverse morphology, which was further characterized by electron microscopy. In some cases, rare degenerating p62- and ubiquitin-positive cells were present in affected regions. Calcifications were present in four cases, being extensive in one. CONCLUSIONS: We present the largest autopsy series of biochemically and genetically confirmed VPS13A disease and identify novel histopathological findings implicating abnormal lipid accumulation. © 2023 International Parkinson and Movement Disorder Society.

Sphingolipid and Phospholipid Levels Are Altered in Human Brain in Chorea-Acanthocytosis.

BACKGROUND: Chorea-acanthocytosis (ChAc) is associated with mutations of VPS13A, which encodes for chorein, a protein implicated in lipid transport at intracellular membrane contact sites. OBJECTIVES: The goal of this study was to establish the lipidomic profile of patients with ChAc. METHODS: We analyzed 593 lipid species in the caudate nucleus (CN), putamen, and dorsolateral prefrontal cortex (DLPFC) from postmortem tissues of four patients with ChAc and six patients without ChAc. RESULTS: We found increased levels of bis(monoacylglycerol)phosphate, sulfatide, lysophosphatidylserine, and phosphatidylcholine ether in the CN and putamen, but not in the DLPFC, of patients with ChAc. Phosphatidylserine and monoacylglycerol were increased in the CN and N-acyl phosphatidylserine in the putamen. N-acyl serine was decreased in the CN and DLPFC, whereas lysophosphatidylinositol was decreased in the DLPFC. CONCLUSIONS: We present the first evidence of altered sphingolipid and phospholipid levels in the brains of patients with ChAc. Our observations are congruent with recent findings in cellular and animal models, and implicate defects of lipid processing in VPS13A disease pathophysiology. © 2023 International Parkinson and Movement Disorder Society.

Diagnostic Uncertainties: Chorea.

Chorea is a hyperkinetic movement disorder with a multitude of potential etiologies, both acquired and inherited. Although the differential diagnosis for new-onset chorea is extensive, there are often clues in the history, exam, and basic testing that can help to narrow the options. Evaluation for treatable or reversible causes should take priority, as rapid diagnosis can lead to more favorable outcomes. While Huntington's disease is most common genetic cause of chorea, multiple phenocopies also exist and should be considered if Huntington gene testing is negative. The decision of what additional genetic testing to pursue should be based on both clinical and epidemiological factors. The following review provides an overview of the many possible etiologies as well as a practical approach for a patient presenting with new-onset chorea.

Health and disability care providers' experiences and perspectives on end-of-life care needs of individuals with long-standing physical disability: A qualitative interview study.

BACKGROUND: Little is known about the specific needs and experiences of individuals with long-standing physical disability at end of life. AIM: To explore health and disability care providers perspectives and experiences in relation to end-of-life care needs of individuals with long-standing physical disability. DESIGN: Qualitative study using reflexive thematic analysis. SETTING/PARTICIPANTS: Semi-structured interviews were conducted with nine health and disability care providers from two Australian states. RESULTS: Five themes were constructed from the data: (1) The significance of place. All participants described how the end-of-life care experience was significantly impacted by the place in which dying occurred. (2) Knowing the person and their needs. Knowledge and familiarity with the individual with long-standing disability were seen as invaluable in terms of providing continued high-quality care. (3) Navigating a new care landscape. For disability support workers, struggling to adapt from providing disability support to end-of-life care was difficult. (4) Complexities of family involvement. Past experiences of families within the healthcare system had resultant impacts on care received by the individual with long-standing disability. (5) Being prepared. Participants felt more was needed in terms of end-of-life planning and discussions around end of life for this cohort. CONCLUSIONS: This research highlights a significant lack of continuity of care and problems at the intersection of the disability and health systems when providing end-of-life care for this cohort. Suggested areas for improvement include team approaches to enable continuity of care and dying in place, and a need for knowledge and skills in this area for all stakeholders.

Shared medical appointments for weight loss: a systematic review.

PURPOSE: Shared medical appointments (SMAs) may help mitigate some of the barriers for managing obesity in primary care. The primary aim of this systematic review was to measure the effect of weight loss SMAs. METHODS: Systematic searches using keywords and Medical Subject Headings for overweight, obesity, and SMAs were conducted in the CENTRAL, Medline Complete, PsycINFO, Scopus, CINAHL, EMBASE, and Web of Science databases with no date limits. Risk of bias was assessed using the Effective Health Practice Project Quality Assessment Tool for Quantitative Studies. RESULTS: Fifteen studies involving weight loss SMAs in adults and children were identified. Six studies had controls. Inconsistency in reporting weight loss or weight change in controlled studies meant that data could not be pooled for meta-analysis. Results from individual studies indicated that SMAs can support adult patients to achieve significant weight loss. Women and older adults were more likely to take up SMA invitations. Results from the 5 studies involving children were less conclusive. Studies involving participants of a higher socioeconomic status tended to report lower attrition than studies involving participants who experienced disadvantage. These findings should be interpreted with caution as all but 1 included study was assessed as being weak in quality. CONCLUSIONS: Overall, SMAs may be of benefit to address obesity in primary care, particularly for women and older adults. Appropriately designed prospective and controlled studies are required to engage their target audience and to assess whether SMAs are superior to other weight loss options in primary care.

Empowerment for behaviour change through social connections: a qualitative exploration of women's preferences in preconception health promotion in the state of Victoria, Australia.

BACKGROUND: Health behaviours in the preconception period have the potential to impact on fertility and pregnancy outcomes, and the health of all women regardless of pregnancy intention. Public awareness of this is low and interventions that promote behaviour change have not been integrated into real-world settings. Aims were to explore women's understandings of health and health behaviours and what supports are important to promote behaviour change in the preconception period. METHODS: This qualitative study is the first phase of a broader co-design project set in the state of Victoria, Australia. Over 3 months, a series of in-depth interviews were conducted with female participants who were intending to become pregnant in the next 2 years (n = 6) and participants who were not intending to become pregnant in the next 2 years (n = 6). Community advisors (n = 8) aged 18-45 years provided feedback throughout the process. Coding of transcripts from interviews and meetings was undertaken by two researchers before a deductive process identified themes mapped to the COM-B framework. RESULTS: Nine themes and eight sub-themes were identified. Participants had a holistic view of health with nutrition, physical activity and sleep being most valued. Social connections were considered as being important for overall health and wellbeing and for promoting health behaviours. The only difference between groups was that pregnancy was an additional motivator for women who were planning to become pregnant in the next 2 years. A range of health information is available from health professionals and other sources. Unlimited access to information was empowering but sometimes overwhelming. Being listened to and shared experiences were aspects of social connections that validated participants and guided them in their decision-making. CONCLUSIONS: Women valued their health and had a holistic view that includes physical, mental and social dimensions. Women viewed social connections with others as an opportunity to be listened to and to gain support that empowers behaviour change. Future interventions to promote behaviour change in preconception women should consider the importance all women placed on social connections and leverage off existing resources to connect women.

Facilitators and barriers to developing romantic and sexual relationships: lived experiences of people with complex communication needs.

The aims of this study were to investigate the lived experiences of people with complex communication needs in developing romantic and sexual relationships, and identify and explore barriers and facilitators they encountered in pursuing these relationships. For the study, nine participants were interviewed. All were at least 21-years-old, used augmentative and alternative communication, and had physical and communication disabilities since childhood. A methodology employing critical hermeneutics, a form of interpretive phenomenology, and Feminist Standpoint Theory was utilized. The World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF) model (2013) was used to develop questions for the semi-structured interviews. Interview data were analyzed using reflexive thematic analysis, with the ICF model and the concept of ableism used to identify four main themes: (a) Attitudes of others (ableism), (b) Communication Within Intimate Moments, (c) Assistance of Support Workers, and (d) Additional Education Related to Sexuality and Disability. Most of the barriers participants encountered related to ableist attitudes they experienced from others. Facilitators included creative communication strategies for intimate moments and using dating websites. The participants' experiences bring attention to the need for changes in policies, practice, and research to further support people with complex communication needs in their quest to develop intimate relationships.

What quality of life domains are most important to older adults in residential care?

Quality of life is a critically important outcome measure in aged care. However, few studies have provided a detailed examination of what quality of life means to older adults living in residential care. In the current study, N = 43 older adults (67 to 99 years) living in six residential aged care facilities in four Australian states took part in semi-structured interviews. Participants had normal cognition through to mild /moderate cognitive impairment as measured by the PAS-Cog, were able to provide informed consent, and could participate in an interview conducted in English. Interviews were transcribed, and data was analyzed in NVivo using thematic analysis. Both physical and psycho-social aspects were identified as important for older adults' quality of life with six key quality of life domains identified: independence, mobility, pain management, social connections, emotional well-being, and activities. More research is needed to test these domains with a more diverse sample of older adults living in residential aged care, in particular older adults from culturally and linguistically diverse communities. Such qualitative work is essential for the development of suitable quality of life measures for this population and provides valuable information to inform improvements to care practices and service provision. Some ways in which the identified quality of life domains could be used to enhance care provision are discussed.

Worldwide barriers to genetic testing for movement disorders.

BACKGROUND AND PURPOSE: Despite enormous advances in identifying genetic variants responsible for many neurological diseases, access to genetic testing may be limited in clinical practice. The objective of this study was to assess worldwide access to genetic tests for movement disorders and factors impacting their utilization. METHODS: The Rare Movement Disorders Study Group of the International Parkinson and Movement Disorder Society designed an online survey electronically mailed to all 7815 members. RESULTS: Survey data completed by 1269 participants from 109 countries were analysed. Limited access to geneticists and genetic counsellors was reported in many world regions compared to Europe and North America. Availability of genetic testing was limited, with rates of access lower than 50%. Genetic testing for chorea was the most commonly available. For parkinsonism, dystonia, ataxia, hereditary spastic paraplegias and metabolic disorders, there was limited access to genetic testing in all countries compared to Europe and North America, with significant differences found for Africa, Central/South America, Asia. In many regions, genetic testing was supported by either private or public funding. Genetic testing was free of charge in Europe according to 63.5% of respondents. In North America, Africa, Central/South America, Asia and the Middle East access to free of charge genetic testing was by far significantly lower compared to Europe. CONCLUSIONS: This survey highlights difficulties in accessing genetic testing and individuals with expertise in genetics at the worldwide level. In addition, major disparities in genetic testing amongst world regions are highlighted, probably due to a variety of factors including financial barriers.

Assessing the relative importance of key quality of life dimensions for people with and without a disability: an empirical ranking comparison study.

BACKGROUND: In economic evaluation, the quality of life of people with a disability has traditionally been assessed using preference-based instruments designed to measure and value quality of life. To provide robust measurement of the effectiveness of programs designed to improve the quality of life of people living with a disability, preference-based measures need to be sufficiently sensitive to detect incremental changes in the quality of life dimensions that are most important to people who have a disability. This study sought to explore whether there was a difference in the ranked order of importance of quality of life dimensions between people with a disability and people without a disability. METHODS: An online survey was developed and administered Australia wide. The first sample (n = 410) comprised adults (aged ≥ 18 years) with a disability (n = 208) and family carers of person/s with a disability who were asked to respond on behalf of the person with a disability (n = 202). The second sample included adults without disability (n = 443). Respondents were asked to rank the importance of 12 quality of life dimensions extracted from the content of established preference-based quality of life measures (EQ-5D, AQoL and ASCOT). RESULTS: People with a disability placed relatively higher importance on broader quality of life dimensions (e.g. Control, Independence, Self-care) relative to health status focused dimensions (e.g. Vision, Hearing, Physical mobility). This distinction was less differentiable for those 'without a disability'. The biggest differences in ranked importance of dimensions were in: Vision ('with disability' = 10th, 'without disability' = 4th), Self-care ('with disability' = 3rd, 'without disability' = 7th) and Mental well-being ('with disability' = 6th, 'without disability' = 2nd). CONCLUSIONS: The relative importance of quality of life dimensions for people with a disability differs to people without a disability. Quality of life is a key outcome for economic evaluation and for assessing the impact of disability care policy and practice in Australia and internationally. It is important that the effectiveness of interventions is measured and valued in ways which are fully reflective of the quality of life preferences of people with a disability.

Developing dimensions for a new preference-based quality of life instrument for older people receiving aged care services in the community.

PURPOSE: To identify the salient quality of life characteristics relevant to older people in receipt of community aged care services in order to develop dimensions for a draft descriptive system for a new preference-based quality of life instrument. METHODS: Forty-one in-depth semi-structured interviews were undertaken with older people (65 years and over) receiving community aged care services across three Australian states to explore quality of life characteristics of importance to them. The data were analysed using framework analysis to extract broader themes which were organised into a conceptual framework. The data were then summarised into a thematic chart to develop a framework matrix which was used to interpret and synthesise the data. Care was taken throughout to retain the language that older people had adopted during the interviews to ensure that appropriate language was used when identifying and developing the quality of life dimensions. RESULTS: The analysis resulted in the identification of five salient quality of life dimensions: independence, social connections, emotional well-being, mobility, and activities. CONCLUSION: This research finds that quality of life for older people accessing aged care services goes beyond health-related quality of life and incorporates broader aspects that transcend health. The findings represent the first stage in a multiphase project working in partnership with older people to develop a new preference-based instrument of quality of life for informing quality assessment and economic evaluation in community aged care. In future work, draft items will be developed from these dimensions and tested in face validity interviews before progressing to further psychometric testing.

Prophylactic antibiotics for adults with chronic obstructive pulmonary disease: a network meta-analysis.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a chronic respiratory condition characterised by persistent respiratory symptoms and airflow limitation. Acute exacerbations punctuate the natural history of COPD and are associated with increased morbidity and mortality and disease progression. Chronic airflow limitation is caused by a combination of small airways (bronchitis) and parenchymal destruction (emphysema), which can impact day-to-day activities and overall quality of life. In carefully selected patients with COPD, long-term, prophylactic use of antibiotics may reduce bacterial load, inflammation of the airways, and the frequency of exacerbations. OBJECTIVES: To assess effects of different prophylactic antibiotics on exacerbations, quality of life, and serious adverse events in people with COPD in three separate network meta-analyses (NMAs), and to provide rankings of identified antibiotics. SEARCH METHODS: To identify eligible randomised controlled trials (RCTs), we searched the Cochrane Airways Group Specialised Register of trials and clinical trials registries. We conducted the most recent search on 22 January 2020. SELECTION CRITERIA: We included RCTs with a parallel design of at least 12 weeks' duration evaluating long-term administration of antibiotics prophylactically compared with other antibiotics, or placebo, for patients with COPD. DATA COLLECTION AND ANALYSIS: This Cochrane Review collected and updated pair-wise data from two previous Cochrane Reviews. Searches were updated and additional studies included. We conducted three separate network meta-analyses (NMAs) within a Bayesian framework to assess three outcomes: exacerbations, quality of life, and serious adverse events. For quality of life, we collected data from St George's Respiratory Questionnaire (SGRQ). Using previously validated methods, we selected the simplest model that could adequately fit the data for every analysis. We used threshold analysis to indicate which results were robust to potential biases, taking into account each study's contributions to the overall results and network structure. Probability ranking was performed for each antibiotic class for exacerbations, quality of life, and serious adverse events. MAIN RESULTS: Characteristics of studies and participants Eight trials were conducted at multiple sites that included hospital clinics or academic health centres. Seven were single-centre trials conducted in hospital clinics. Two trials did not report settings. Trials durations ranged from 12 to 52 weeks. Most participants had moderate to severe disease. Mean age ranged from 64 years to 73 years, and more males were recruited (51% to 100%). Forced expiratory volume in one second (FEV1) ranged from 0.935 to 1.36 L. Most participants had previous exacerbations. Data from 12 studies were included in the NMAs (3405 participants; 16 treatment arms including placebo). Prophylactic antibiotics evaluated were macrolides (azithromycin and erythromycin), tetracyclines (doxycyclines), quinolones (moxifloxacin) and macrolides plus tetracyclines (roxithromycin plus doxycycline). Risk of bias and threshold analysis Most studies were at low risk across domains, except detection bias, for which only seven studies were judged at low risk. In the threshold analysis for exacerbations, all comparisons in which one antibiotic was compared with another were robust to sampling variation, especially macrolide comparisons. Comparisons of classes with placebo were sensitive to potential bias, especially macrolide versus placebo, therefore, any bias in the comparison was likely to favour the active class, so any adjustment would bring the estimated relative effect closer to the null value, thus quinolone may become the best class to prevent exacerbations. Exacerbations Nine studies were included (2732 participants) in this NMA (exacerbations analysed as time to first exacerbation or people with one or more exacerbations). Macrolides and quinolones reduced exacerbations. Macrolides had a greater effect in reducing exacerbations compared with placebo (macrolides: hazard ratio (HR) 0.67, 95% credible interval (CrI) 0.60 to 0.75; quinolones: HR 0.89, 95% CrI 0.75 to 1.04), resulting in 127 fewer people per 1000 experiencing exacerbations on macrolides. The difference in exacerbations between tetracyclines and placebo was uncertain (HR 1.29, 95% CrI 0.66 to 2.41). Macrolides ranked first (95% CrI first to second), with quinolones ranked second (95% CrI second to third). Tetracyclines ranked fourth, which was lower than placebo (ranked third). Contributing studies were considered as low risk of bias in a threshold analysis. Quality of life (SGRQ) Seven studies were included (2237 participants) in this NMA. SGRQ scores improved with macrolide treatment compared with placebo (fixed effect-fixed class effect: mean difference (MD) -2.30, 95% CrI -3.61 to -0.99), but the mean difference did not reach the minimally clinical important difference (MCID) of 4 points. Tetracyclines and quinolones did not improve quality of life any more than placebo, and we did not detect a difference between antibiotic classes. Serious adverse events Nine studies were included (3180 participants) in the NMA. Macrolides reduced the odds of a serious adverse event compared with placebo (fixed effect-fixed class effect: odds ratio (OR) 0.76, 95% CrI 0.62 to 0.93). There was probably little to no difference in the effect of quinolone compared with placebo or tetracycline plus macrolide compared with placebo. There was probably little to no difference in serious adverse events between quinolones or tetracycline plus macrolide. With macrolide treatment 49 fewer people per 1000 experienced a serious adverse event compared with those given placebo. Macrolides ranked first, followed by quinolones. Tetracycline did not rank better than placebo. Drug resistance Ten studies reported drug resistance. Results were not combined due to variation in outcome measures. All studies concluded that prophylactic antibiotic administration was associated with the development of antimicrobial resistance. AUTHORS' CONCLUSIONS: This NMA evaluated the safety and efficacy of different antibiotics used prophylactically for COPD patients. Compared to placebo, prolonged administration of macrolides (ranked first) appeared beneficial in prolonging the time to next exacerbation, improving quality of life, and reducing serious adverse events. No clear benefits were associated with use of quinolones or tetracyclines. In addition, antibiotic resistance was a concern and could not be thoroughly assessed in this review. Given the trade-off between effectiveness, safety, and risk of antibiotic resistance, prophylactic administration of antibiotics may be best reserved for selected patients, such as those experiencing frequent exacerbations. However, none of the eligible studies excluded patients with previously isolated non-tuberculous mycobacteria, which would contraindicate prophylactic administration of antibiotics, due to the risk of developing resistant non-tuberculous mycobacteria.

The integration of mixed methods data to develop the quality of life - aged care consumers (QOL-ACC) instrument.

BACKGROUND: This paper describes the collection and integration of mixed methods data to facilitate the final selection of items for the Quality of Life - Aged Care Consumers (QOL-ACC) instrument. The aim of the wider project is to develop a preference-based quality of life instrument that can be used for quality assessment and economic evaluation. Older people have been involved at every stage of the development of the QOL-ACC to ensure that the final instrument captures their perspectives and preferences. METHODS: Mixed methods data was collected on draft items for the QOL-ACC instrument across six key quality of life dimensions (mobility, pain management, emotional well-being, independence, social connections, and activities). Qualitative face validity data was collected from older people (aged 66 to 100 years) living in the community and in residential aged care via semi-structured interviews (n = 59). Quantitative data was collected from older people (aged 65 to 91 years) receiving aged care services in the community via an online survey (n = 313). A traffic light pictorial approach was adopted as a practical and systematic way to categorise and present data in a meaningful way that was easy for non-academic workshop members to understand and to be able to discuss the relative merits of each draft item. RESULTS: The traffic light approach supported the involvement of consumer and aged care provider representatives in the selection of the final items. Six items were selected for the QOL-ACC instrument with one item representing each of the six dimensions. CONCLUSIONS: This methodological approach has ensured that the final instrument is psychometrically robust as well as meaningful, relevant and acceptable to aged care consumers and providers.

"We are only looking at the tip of the iceberg in infertility": perspectives of health providers about fertility issues and management among Aboriginal and Torres Strait Islander people.

INTRODUCTION: Aboriginal and Torres Strait Islander women and men are disproportionately affected by a range of risk factors for infertility. However, remarkably little is known about the prevalence of infertility in this group, or how Aboriginal and Torres Strait Islander people access fertility treatments including assisted reproductive technology (ART). This qualitative study aims to explore health care provider (HCP) perspectives on the health burden of infertility among Aboriginal and Torres Strait Islander people, as well as factors that may affect access to infertility treatment for this group. METHOD: Semi-structured interviews were conducted with HCPs (8 doctors; 3 nurses and 1 Aboriginal Health Practitioner) working in fertility care in the Northern Territory, Australia. Transcribed interviews were analysed using an iterative thematic approach using the NVivo-9 software package. RESULTS: Providers perceive infertility as an underestimated health issue in this patient population, reporting a high prevalence of infertility-related risk factors but fewer clinical encounters of diagnosis and treatment. Perceived barriers to accessing fertility care included cultural differences such as the shame and stigma associated with reproductive health and the separation of men's business and women's business; service-related barriers such as limited timely and affordable access to specialist health services and; a lack of culturally responsive and appropriate fertility services. Providers had mixed opinions on their role in ameliorating inequities of access, and hence a range of strategies to address barriers were suggested. These included a greater patient education, ongoing patient support and providing a culturally safe environment. CONCLUSION: The current study adds to the understanding of how Aboriginal and Torres Strait Islander people access fertility treatments. There is a need for further research to quantify infertility in Aboriginal and Torres Strait Islander people, investigate community perceptions towards infertility and identify community-driven priorities to improve access to fertility care for this population.

Interventions improving health professionals' practice for addressing patients' weight management behaviours: systematic review of reviews.

Health professionals require education and training to implement obesity management guidelines and ultimately impact on the health outcomes experienced by their patients. Therefore, a systematic review of systematic reviews that evaluated interventions designed to change the practice of health professionals when addressing diet and physical activity with their patients was conducted. MEDLINE Complete; Cochrane database of systematic reviews; PsycINFO; CINAHL Complete; Global Health; Embase; INFORMIT: Health Subset; Health System Evidence and RX for change were searched in March 2019, with no date or language limits. Identified references underwent screening, full-text analyses and data extraction in duplicate. The search identified 15 230 references. Five systematic reviews that provided a narrative syntheses of a combined 38 studies were included. Health professional participants generally reported being satisfied with the training interventions. Heterogeneity between and within included reviews, non-controlled designs of individual studies and low quality of evidence at an individual study level and review level made it difficult to draw firm conclusions regarding what interventions are most effective in changing health professionals' knowledge, skills, self-efficacy, attitudes and practice. However, similar gaps in the literature were identified across included reviews. Key areas that could be addressed in future interventions including organization and system-level barriers to providing advice, health professionals' attitudes and motivation and weight stigma have been highlighted. Health professionals and patients could be more involved in the planning and development of interventions that work towards improving diet and physical activity advice and support provided in healthcare.

Maternal obesity prevention: The Health in Preconception, Pregnancy, and Postpartum Early- and Mid-Career Researcher Collective.

There is a clear impetus for researchers to facilitate cross-sector and interdisciplinary collaboration to achieve collective action for maternal obesity prevention. Building early- and mid-career researchers' capacity to sustainably develop collective action into the future is key. Therefore, the national Health in Preconception, Pregnancy, and Postpartum Early- and Mid-career Researcher Collective (HiPPP EMR-C) was formed. Here, we describe the aim, key goals and future directions of the HiPPP EMR-C. Guided by the Simplified Framework for Understanding Collective Action, we aim to build our capacity as researchers, form policy stakeholder relationships and focus on generating impact to optimise maternal and child health and well-being.

Preconception women's views of promoting preconception women's health in Australia.

ISSUE ADDRESSED: Sub-optimal lifestyle choices made long before pregnancy have the potential to impact negatively maternal health and pregnancy outcomes. However, many women are unaware of this and do not seek preconception health advice. METHODS: Using a descriptive qualitative approach, nonpregnant women (n = 31) aged 18-45 years were purposively recruited to participate in a focus group (n = 7) that explored how preconception health is prioritised and how to increase women's awareness and uptake of healthy lifestyle behaviours in the preconception period. Focus group transcripts were coded by two researchers and an inductive process was used to categorise codes into themes. RESULTS: Two themes and five sub-themes relating to the aims of this study were identified. Participants believed preconception health to be important for all women, while admitting that was not a high priority if not planning a pregnancy. Participants suggested a range of interventions that spanned the social-ecological model of health to engage preconception women in preventive actions and promote preconception health. These interventions included having access to reputable and easily accessible online sources of preconception health information, education and at secondary schools and public health campaigns. CONCLUSIONS: Future initiatives to engage preconception women should span the social-ecological model of health and consider women's personal preferences for accessible and tailored preconception health information and support at individual, interpersonal, community and organisational levels, as well as in the broader environment. SO WHAT?: This research provides guidance to those in health promotion when planning future initiatives to promote and protect women's preconception health.
