A simple mechanism for collective decision-making in the absence of payoff information.

Animals are often faced with time-critical decisions without prior information about their actions' outcomes. In such scenarios, individuals budget their investment into the task to cut their losses in case of an adverse outcome. In animal groups, this may be challenging because group members can only access local information, and consensus can only be achieved through distributed interactions among individuals. Here, we combined experimental analyses with theoretical modeling to investigate how groups modulate their investment into tasks in uncertain conditions. Workers of the arboreal weaver ant Oecophylla smaragdina form three-dimensional chains using their own bodies to bridge vertical gaps between existing trails and new areas to explore. The cost of a chain increases with its length because ants participating in the structure are prevented from performing other tasks. The payoffs of chain formation, however, remain unknown to the ants until the chain is complete and they can explore the new area. We demonstrate that weaver ants cap their investment into chains, and do not form complete chains when the gap is taller than 90 mm. We show that individual ants budget the time they spend in chains depending on their distance to the ground, and propose a distance-based model of chain formation that explains the emergence of this tradeoff without the need to invoke complex cognition. Our study provides insights into the proximate mechanisms that lead individuals to engage (or not) in collective actions and furthers our knowledge of how decentralized groups make adaptive decisions in uncertain conditions.

Women's experience of perinatal support in a high migrant Australian population during the COVID-19 pandemic: a mixed methods study.

BACKGROUND: As a COVID-19 risk mitigation measure, Australia closed its international borders for two years with significant socioeconomic disruption including impacting approximately 30% of the Australian population who are migrants. Migrant populations during the peripartum often rely on overseas relatives visiting for social support. High quality social support is known to lead to improved health outcomes with disruption to support a recognised health risk. AIM: To explore women's experience of peripartum social support during the COVID-19 pandemic in a high migrant population. To quantify type and frequency of support to identify characteristics of vulnerable perinatal populations for future pandemic preparedness. METHODS: A mixed methods study with semi-structured interviews and a quantitative survey was conducted from October 2020 to April 2021. A thematic approach was used for analysis. RESULTS: There were 24 participants interviewed both antenatally and postnatally (22 antenatal; 18 postnatal). Fourteen women were migrants and 10 Australian born. Main themes included; 'Significant disruption and loss of peripartum support during the COVID-19 pandemic and ongoing impact for migrant women'; 'Husbands/partners filling the support gap' and 'Holding on by a virtual thread'. Half of the participants felt unsupported antenatally. For Australian born women, this dissipated postnatally, but migrants continued to feel unsupported. Migrant women discussed partners stepped into traditional roles and duties of absent mothers and mothers-in-law who were only available virtually. CONCLUSION: This study identified disrupted social support for migrant women during the pandemic, providing further evidence that the pandemic has disproportionately impacted migrant populations. However, the benefits identified in this study included high use of virtual support, which could be leveraged for improving clinical care in the present and in future pandemics. The COVID-19 pandemic impacted most women's peripartum social support with migrant families having ongoing disruption. Gains in the pandemic included greater gender equity for domestic work as husbands/partners increased their contribution to domestic work and childcare.

A mixed methods study of Aboriginal health workers' and exercise physiologists' experiences of co-designing chronic lung disease 'yarning' education resources.

BACKGROUND: Despite the high incidence of chronic obstructive pulmonary disease (COPD) in Aboriginal communities in Australia, Aboriginal Health Workers (AHWs) have limited knowledge about effective management. AIM: To evaluate an online education program, co-designed with AHWs and exercise physiologists (EPs) or physiotherapists (PTs), to increase knowledge about COPD and its management. METHODS: AHWs and EPs from four Aboriginal Community Controlled Health Services (ACCHS) were recruited. An Aboriginal researcher and a physiotherapist experienced in COPD management and pulmonary rehabilitation (PR) delivered seven online education sessions. These sessions used co-design principles and an Aboriginal pedagogy framework '8 Ways of learning', which incorporates Aboriginal protocols and perspectives to realign teaching techniques and strengthen learning outcomes. Topics covered were: How the lungs work; What is COPD; Medications and how to use inhalers and COPD Action Plans; Why exercise is important; Managing breathlessness; Healthy eating; Managing anxiety and depression. After each session, AHWs with support from EPs, co-designed education 'yarning' resources using Aboriginal ways of learning to ensure topics were culturally safe for the local Aboriginal community and practiced delivering this at the following session. At the end of the program participants completed an anonymous online survey (5-point Likert scale) to assess satisfaction, and a semi-structured interview about their experience of the online education. RESULTS: Of the 12 participants, 11 completed the survey (7 AHWs, 4 EPs). Most (90%) participants strongly agreed or agreed that the online sessions increased knowledge and skills they needed to support Aboriginal patients with COPD. All (100%) participants felt: their cultural perspectives and opinions were valued and that they were encouraged to include cultural knowledge. Most (91%) reported that delivering their own co-designed yarning scripts during the online sessions improved their understanding of the topics. Eleven participants completed semi-structured interviews about participating in online education to co-design Aboriginal 'yarning' resources. Themes identified were: revealing the Aboriginal lung health landscape; participating in online learning; structuring the online education sessions; co-designing with the facilitators. CONCLUSIONS: Online education using co-design and 8 Ways of learning was rated highly by AHWs and EPs for improving COPD knowledge and valuing cultural perspectives. The use of co-design principles supported the cultural adaptation of COPD resources for Aboriginal people with COPD. TRIAL REGISTRATION: PROSPERO (registration number: CRD42019111405).

COVID-19 vaccine acceptance among pregnant women and the reasons for hesitancy: A multi-centre cross-sectional survey.

BACKGROUND: On 9 June 2021, the Australian Technical Advisory Group on Immunisation and Royal Australian and New Zealand College of Obstetricians and Gynaecologists recommended that pregnant women receive Comirnaty (Pfizer) messenger RNA vaccine at any stage of pregnancy. AIM: This multi-centre study aimed to assess vaccine acceptance, reasons for hesitancy and determine if differences exist between health districts, to inform future policy strategies for COVID-19 vaccination in pregnancy. MATERIALS AND METHODS: An online survey (developed based on the World Health Organization Behavioural and Social Drivers survey and modified for the pregnant population) was administered to a sample population of pregnant women attending antenatal clinics at two metropolitan hospitals (Westmead and Royal North Shore Hospital (RNSH)) in New South Wales between 15 September 2021 and 22 October 2021. RESULTS: There were 287 pregnant women surveyed (Westmead 198 (69%), RNSH 66 (23%), no site 23 (8%)). There was a significantly lower Socio-Economic Indexes for Areas score (5.66 vs 9.45, P = 0.001), fewer women born in Australia (37% vs 53%, P = 0.02) and higher number of children (0.77 vs 0.41, P = 0.01) among Westmead respondents. There was lower vaccination uptake (68% vs 86%, P = 0.01) and willingness to receive vaccine (68% vs 88% P = 0.01) at Westmead compared to RNSH. There was an increased proportion of respondents who were concerned that the vaccine could cause harm to the unborn baby at Westmead (38% vs 11%, P = 0.01). CONCLUSIONS: Along with healthcare provider recommendation for vaccination in pregnancy, materials should be targeted to specific safety concerns of pregnant women.

Structural Characterization and Spatial Mapping of Tetrodotoxins in Australian Polyclads.

Tetrodotoxin (TTX) is a potent marine neurotoxin that occurs in several Australian phyla, including pufferfish, toadfish, gobies, and the blue-ringed octopus. These animals are partially immune, and TTX is known to bioaccumulate and subject to trophic transfer. As such, it could be more ubiquitously distributed in animals than is currently known. Flatworms of the order Polycladida are commonly occurring invertebrates in intertidal ecosystems and are especially diverse in Australian waters. While TTX has been identified in polyclads from Japan and New Zealand, Australian species have yet to be tested. In this study, several eastern Australian polyclad flatworm species from the suborders Cotylea and Acotylea were tested for TTX and analogs by HILIC-HRMS to understand the distribution of this toxin within these suborders. Herein, we report the detection of TTX and some known analogs in polyclad species, one of which is a pest to shellfish aquaculture. We also report, for the first time, the application of MALDI mass spectrometry imaging utilized to map TTX spatially within the intestinal system of polyclads. The identification of TTX and its analogs in Australian flatworms illustrates a broader range of toxic flatworms and highlights that analogs are important to consider when studying the distributions of toxins in animals.

Natural Products in Polyclad Flatworms.

Marine invertebrates are promising sources of novel bioactive secondary metabolites, and organisms like sponges, ascidians and nudibranchs are characterised by possessing potent defensive chemicals. Animals that possess chemical defences often advertise this fact with aposematic colouration that potential predators learn to avoid. One seemingly defenceless group that can present bright colouration patterns are flatworms of the order Polycladida. Although members of this group have typically been overlooked due to their solitary and benthic nature, recent studies have isolated the neurotoxin tetrodotoxin from these mesopredators. This review considers the potential of polyclads as potential sources of natural products and reviews what is known of the activity of the molecules found in these animals. Considering the ecology and diversity of polyclads, only a small number of species from both suborders of Polycladida, Acotylea and Cotylea have been investigated for natural products. As such, confirming assumptions as to which species are in any sense toxic or if the compounds they use are biosynthesised, accumulated from food or the product of symbiotic bacteria is difficult. However, further research into the group is suggested as these animals often display aposematic colouration and are known to prey on invertebrates rich in bioactive secondary metabolites.

Experiences of health service literacy and access amongst Australian young adults from migrant backgrounds.

ISSUE ADDRESSED: We currently know very little about the attitudes of young adult Australians from migrant backgrounds towards health service utilisation. This qualitative study aimed to explore their experiences of accessing health services and identify barriers and facilitators to health service utilisation. METHODS: Semi-structured interviews were conducted with young people aged between 18-24 and living in Greater Western Sydney. Interview questions focused on facilitators and barriers to health service access. NVivo 11 was used to facilitate thematic analysis of the interviews. RESULTS: Twenty-five young adults between 18-24 years from migrant backgrounds participated. Twenty semi-structured individual interviews and one group interview with five participants were conducted. Analysis identified themes relating to health literacy, cultural factors and quality of care and showed the importance of families, the education system and service outreach in facilitating access. CONCLUSIONS: Findings indicate that more effective delivery of health services information in education, positive engagement between service-providers and service-users, and age-appropriate, culturally considerate health promotion strategies are needed to overcome barriers to health services accessibility. SO WHAT?: The results show the importance of families and communities, the education system and health service outreach in facilitating health service access for young people from migrant backgrounds. The paper highlights the need for more effective health promotion strategies targeting this group, their families and communities. To increase access, health promotion practitioners need to actively reach out to families and young people from migrant backgrounds through education and community-relevant forums.

Reducing emergency department presentations among chronically ill patients in Western Sydney: a key role for coordinated primary care.

Coordination of health services is thought to improve health outcomes for patients with chronic and complex illness; however, there is limited quantitative evidence for the effectiveness of coordinated care programs. HealthOne Mount Druitt (HOMD) is a coordinated care program operating in a disadvantaged area of Western Sydney, Australia. It operates as a combination 'virtual' and 'hub and spoke' model, with care coordination provided by liaison nurses. We aimed to determine whether there were changes in the number of emergency department (ED) presentations, length of stay, and community health referrals in the 12 months following enrolment in HOMD, compared to the 12 months prior. A quantitative survey was also conducted to determine the perspectives of service providers on key aspects of HOMD. Enrolment in HOMD was followed by reductions in both the number of ED presentations and the amount of time spent by patients in the ED. Community health referrals were increased, and the pattern of referral to different types of community health services was altered. This study provides quantitative evidence that a coordinated care intervention improves patient health outcomes.

Role of the GP liaison nurse in a community health program to improve integration and coordination of services for the chronically ill.

This paper explores the role of the General Practitioner Liaison Nurse (GPLN) in improving integration and coordination of services within Primary Health Care. This position can play a major role in care coordination and cultural change. The GPLN within HealthOne Mt Druitt (HOMD) identifies patients' needs and facilitates communication, case conferencing and care coordination between health and other providers. The priority areas of children and their families at risk or with significant unmet needs, and chronic aged and complex care, were identified as target areas. This paper focuses on the GPLN within the chronic aged and complex care service model. The GPLN within HOMD was able to improve coordination and integration of services for patients of the facility. Activities included organising multidisciplinary services and addressing psychosocial issues. Patients and community health staff identified the importance of the role for improving coordination and integration of services. Decision and policy makers saw the position as vital to the implementation, operation and sustainability of HOMD.

Coordinated care versus standard care in hospital admissions of people with chronic illness: a randomised controlled trial.

OBJECTIVE: To determine whether Care Navigation (CN), a nurse-led hospital-based coordinated care intervention, reduced the use of hospital services and improved quality of life for patients with chronic illness. DESIGN: Randomised controlled trial; participants were allocated to CN or standard care. PARTICIPANTS AND SETTING: Patients with chronic illness presenting to the emergency department of Nepean Hospital, Sydney, New South Wales. High-risk status for an unplanned admission was defined as i) three or more unplanned hospital admissions in 12 months for patients aged ≥ 70 or at least one admission for cardiac or respiratory disease in patients aged 16-69 years; or ii) judged by a CN nurse to be high risk and likely to benefit. MAIN OUTCOME MEASURES: Numbers of re-presentations or readmissions, quality of life, time to re-presentation, readmission or death, length of stay, and access to hospital and community health services. RESULTS: 500 participants were randomised between May 2010 and February 2011; 359 by previous unplanned admission and 141 by clinical impression. The CN group received more community health services (rate ratio, 1.94; 95% CI, 1.35-2.81; P < 0.001) than participants receiving standard care; however, this did not result in statistically significant differences in number of re-presentations (rate ratio, 0.83; 95% CI, 0.68-1.01; P = 0.07), number of readmissions (rate ratio, 0.85; 95% CI, 0.70-1.04; P = 0.11), quality of life at 24 months (mean difference, 0; 95% CI, - 0.10 to 0.09, P = 0.93), or other measures. CONCLUSIONS: CN did not improve quality of life or reduce unplanned hospital presentations or admissions despite community health services almost doubling. Future service development should explore potential benefits of linking navigated intrahospital care to ongoing, proactive care planning and delivery in the community.

Non-communicable diseases and implications for medical practice in Australia: a framework for analysis.

Non-communicable diseases (NCDs) have become leading causes of mortality and morbidity as part of historical epidemiological, demographic and nutritional transitions. There has been considerable historical analysis of the immediate and underlying causes of this change in the impacts of communicable diseases and NCDs, but far less historical analysis of how this transition has shaped medical practice. We lay out a framework for future historical analysis by proposing four domains of inquiry into key areas of change: changes in the concept of disease; evolution of medical technology; changes in workforce, including variation in roles and emerging areas of specialisation; and changes in health care structures including models of care, government responses and transitioning health systems. Our aim is to encourage analysis that takes into account key features in each of the four domains, thus enabling a more complete understanding of why, how and under what circumstances NCDs have had an effect on medical practice.

Randomised Controlled Trial of a Customised Text Messaging and Activity Monitor Program for Lifestyle Improvement after Gestational Diabetes.

Gestational diabetes (GDM) is associated with a long-term risk of diabetes. We aimed to determine whether a text-messaging-based lifestyle support program would improve diabetes risk factors following GDM. Women with GDM were randomised following delivery to receive four text messages per week supporting a healthy lifestyle and parenting for 6 months, with feedback from an activity monitor (intervention), or to receive the activity monitor only (control). The primary outcome was a composite of weight, physical activity and dietary goals. There were 177 women randomised, with 88 intervention and 89 control participants. All the participants experienced COVID-19 lockdowns during the study. Six-month primary outcome data were obtained for 57 intervention participants and 56 controls. There were 7/57 (12%) intervention and 6/56 (11%) control participants who met the primary outcome (relative risk, 1.08; 95%CI, 0.63-1.85; p = 0.79). Two intervention participants met the dietary goals compared to none of the control participants (p = NS). The intervention participants were more likely to record >1000 steps/day (on 102 ± 59 vs. 81 ± 59 days, p = 0.03). When analysed monthly, this was not initially different but became significant 3-6 months post-partum. Interviews and surveys indicated that with the Intervention, healthier choices were made, but these were negatively impacted by COVID-19 restrictions. Participants found the messages motivational (74%) and the activity monitor useful (71%). In conclusion, no improvement in the diabetes risk factors occurred among the women receiving the text messaging intervention when affected by COVID-19 restrictions.

From Denmark to Delhi: the multisectoral challenge of regulating trans fats in India.

OBJECTIVE: India has proposed legislating an upper limit of trans fat in partially hydrogenated vegetable oils and mandating trans fat labelling in an effort to reduce intakes. The objective of the present study was to examine the complexities of regulating trans fat in India by examining the policy processes involved and the perceived implementation challenges. DESIGN: Semi-structured interviews (n 18) were conducted with key informants from various sectors. Interviewees were asked about sources of trans fat in the food supply, existing policies that may influence trans fats and perceived challenges related to the proposed trans fat regulation, in addition to questions tailored to their area of expertise. Interview data were organised based on common themes. SETTING: Interviews were conducted in India. SUBJECTS: Interviewees were key informants from various sectors including agriculture, trade, industry and health. RESULTS: Several themes were identified related to the complexity of regulating trans fat in India. A lack of trans fat awareness, the large unorganised retail sector, a need for suitable alternative products that are both acceptable to consumers and affordable, and a need to build capacity were crucial factors affecting India's ability to successfully regulate trans fat. The limited number of food inspectors will create an additional challenge in terms of enforcement of trans fat regulation. CONCLUSIONS: Although India will face challenges in regulating trans fat, legislating an upper limit of trans fat in partially hydrogenated vegetable oils will likely be the most effective approach to reducing it in the food supply. Ongoing engagement with industry, agriculture, trade and processing sectors will prove essential in terms of product reformulation.

Implementation and effectiveness of 'care navigation', coordinated management for people with complex chronic illness: rationale and methods of a randomised controlled trial.

BACKGROUND: Chronic illness is a significant driver of the global burden of disease and associated health care costs. People living with severe chronic illness are heavy users of acute hospital services; better coordination of their care could potentially improve health outcomes while reducing hospital use. The Care Navigation trial will evaluate an in-hospital coordinated care intervention on health service use and quality of life in chronically ill patients. METHODS/DESIGN: A randomised controlled trial in 500 chronically ill patients presenting to the emergency department of a hospital in Western Sydney, Australia. Participants have three or more hospital admissions within a previous 12 month period and either aged ≥70 years; or aged ≥45 years and of Aboriginal or Torres Strait Islander descent; or aged ≥ 16 with a diagnosis of a respiratory or cardiology related illness. Patients are randomised to either the coordinated care program (Care Navigation), or to usual care. The Care Navigation program consists of dedicated nurses who conduct patient risk assessments, oversee patient nursing while in hospital, and guide development of a care plan for the management of chronic illness after being discharged from hospital. These nurses also book community appointments and liaise with general practitioners. The main outcome variables are the number of emergency department re-presentations and hospital readmissions, and quality of life during a 24 month follow-up. Secondary outcomes are length of hospital stay, mortality, time to first hospital re-admission, time to first emergency department re-presentation, patient satisfaction, adherence to prescribed medications, amount and type of in-hospital referrals made for consultations and diagnostic testing, and the number and type of community health referrals. A process evaluation and economic analysis will be conducted alongside the randomised trial. DISCUSSION: A trial of in-hospital care coordination may support recent evidence that engaging primary health services in care plans linked to multidisciplinary team support improves patient outcomes and reduces costs to the health system. This will inform local, national and international health policy. TRIAL REGISTRATION: Australia New Zealand Clinical Trials Registry ACTRN12609000554268.

International responses addressing the under-representation of older people in clinical research.

Older people (aged 65 years +) are under-represented in clinical research across many disease areas. Such exclusions limit the generalisability of trial results and can lead to a gap in critical knowledge regarding the efficacy and safety of interventions in older age groups. International bodies and regulators have addressed this issue to varying degrees. The USA's Food and Drug Administration (FDA) has produced regular non-binding guidance about the inclusion of older trial participants, while the National Institutes of Health's (NIH) binding regulations mean that those seeking research funding must include participants of all ages unless there are scientific or ethical reasons to exclude them. European regulations governing clinical trials of new medications require that participants represent the population groups that are likely to use the product being tested, while Britain highlights the need to improve trial participation of under-served groups, which include older people. Australian clinical trial guidelines point to the potential problem of excluding some groups from research but do not specifically address older participants. While current international approaches may provide some improvements in trial representation, additional strategies are required to promote clinical research that better reflects populations seen in clinical practice. Australia could benefit from clinical trial guidance that highlights the specific issue of the under-representation of older participants and outlines strategies to facilitate greater inclusion. This article provides an overview and critique of the current approaches to the inclusion of older people in clinical research and highlights policy gaps and limitations of current strategies.

Previous High-Intensity Breastfeeding Lowers the Risk of an Abnormal Fasting Glucose in a Subsequent Pregnancy Oral Glucose Tolerance Test.

Breastfeeding is associated with reduced lifetime cardiometabolic risk, but little is known regarding the metabolic benefit in a subsequent pregnancy. The primary aim of this study was to investigate the association between breastfeeding duration and intensity and next pregnancy oral glucose tolerance test (OGTT) results. A retrospective cohort study was conducted from March 2020 to October 2022. All multiparous women who met inclusion criteria and gave birth during the study period were eligible for inclusion. Analysis was stratified by risk for gestational diabetes (GDM). High GDM risk criteria included previous GDM and BMI > 35 kg/m2. The association between breastfeeding duration and high-intensity breastfeeding (HIBF) and subsequent pregnancy OGTT were assessed with multivariate logistic models adjusted for statistically and clinically relevant covariables. There were 5374 multiparous participants who met the inclusion criteria for analysis. Of these, 61.7% had previously breastfed for >6 months, and 43.4% were at high risk for GDM. HIBF was associated with 47% reduced odds of an abnormal fasting glucose in a subsequent pregnancy OGTT (aOR 0.53; 95%CI 0.38-0.75; p < 0.01). There was no association between HIBF and other glucose results on the OGTT. Women who smoked were least likely to breastfeed at high intensity (aOR 0.31; 95%CI 0.21-0.47; p < 0.01). South Asian women had 65% higher odds of HIBF than women who identified as White/European (aOR 1.65; 1.36-2.00; p < 0.01). This study highlights the importance of exclusive breastfeeding to potentially reduce the prevalence of GDM and may also translate into long-term reduction of cardiometabolic risk.

Exploring the COVID-19 pandemic experience of maternity clinicians in a high migrant population and low COVID-19 prevalence country: A qualitative study.

BACKGROUND: Australia experienced a low prevalence of COVID-19 in 2020 compared to many other countries. However, maternity care has been impacted with hospital policy driven changes in practice. Little qualitative research has investigated maternity clinicians' perception of the impact of COVID-19 in a high-migrant population. AIM: To investigate maternity clinicians' perceptions of patient experience, service delivery and personal experience in a high-migrant population. METHODS: We conducted semi-structured in-depth interviews with 14 maternity care clinicians in Sydney, New South Wales, Australia. Interviews were conducted from November to December 2020. A reflexive thematic approach was used for data analysis. FINDINGS: A key theme in the data was 'COVID-19 related travel restrictions result in loss of valued family support for migrant families'. However, partners were often 'stepping-up' into the role of missing overseas relatives. The main theme in clinical care was a shift in healthcare delivery away from optimising patient care to a focus on preservation and safety of health staff. DISCUSSION: Clinicians were of the view migrant women were deeply affected by the loss of traditional support. However, the benefit may be the potential for greater gender equity and bonding opportunities for partners. Conflict with professional beneficence principles and values may result in bending rules when a disconnect exists between relaxed community health orders and restrictive hospital protocols during different phases of a pandemic. CONCLUSION: This research adds to the literature that migrant women require individualised culturally safe care because of the ongoing impact of loss of support during the COVID-19 pandemic.

Investigating service delivery and perinatal outcomes during the low prevalence first year of COVID-19 in a multiethnic Australian population: a cohort study.

OBJECTIVE: Investigate the impact of the COVID-19 pandemic on perinatal outcomes in an Australian high migrant and low COVID-19 prevalent population to identify if COVID-19 driven health service changes and societal influences impact obstetric and perinatal outcomes. DESIGN: Retrospective cohort study with pre COVID-19 period 1 January 2018-31 January 2020, and first year of global COVID-19 period 1 February 2020-31 January 2021. Multivariate logistic regression analysis was conducted adjusting for confounders including age, area-level socioeconomic status, gestation, parity, ethnicity and body mass index. SETTING: Obstetric population attending three public hospitals including a major tertiary referral centre in Western Sydney, Australia. PARTICIPANTS: Women who delivered with singleton pregnancies over 20 weeks gestation. Ethnically diverse women, 66% overseas born. There were 34 103 births in the district that met inclusion criteria: before COVID-19 n=23 722, during COVID-19 n=10 381. MAIN OUTCOME MEASURES: Induction of labour, caesarean section delivery, iatrogenic and spontaneous preterm birth, small for gestational age (SGA), composite neonatal adverse outcome and full breastfeeding at hospital discharge. RESULTS: During the first year of COVID-19, there was no change for induction of labour (adjusted OR, aOR 0.97; 95% CI 0.92 to 1.02, p=0.26) and a 25% increase in caesarean section births (aOR 1.25; 95% CI 1.19 to 1.32, p<0.001). During the COVID-19 period, we found no change in iatrogenic preterm births (aOR 0.94; 95% CI 0.80 to 1.09) but a 15% reduction in spontaneous preterm birth (aOR 0.85; 95% CI 0.75 to 0.97, p=0.02) and a 10% reduction in SGA infants at birth (aOR 0.90; 95% CI 0.82 to 0.99, p=0.02). Composite adverse neonatal outcomes were marginally higher (aOR 1.08; 95% CI 1.00 to 1.15, p=0.04) and full breastfeeding rates at hospital discharge reduced by 15% (aOR 0.85; 95% CI 0.80 to 0.90, p<0.001). CONCLUSION: Despite a low prevalence of COVID-19, both positive and adverse obstetric outcomes were observed that may be related to changes in service delivery and interaction with healthcare providers. Further research is suggested to understand the drivers for these changes.

Older Adults' Self-Perceptions of Aging and Being Older: A Scoping Review.

BACKGROUND AND OBJECTIVES: Older adults' self-perceptions of aging and being older can influence well-being and quality of life. This systematic scoping review aimed to map out current research on older adults' self-perceptions of aging and being older. RESEARCH DESIGN AND METHODS: The scoping review followed Arksey and O'Malley's methodological framework. A total of 5,037 records were identified (duplicates removed). After screening, a final 148 papers were included. Descriptives, including year of publication, methodology, age, gender, and location of participants, were calculated. Thematic analyses were conducted examining ways in which the topic was conceptualized. RESULTS: The most frequent method used in the research was quantitative. Participants were from 38 different countries. There were more female participants than male. Seven themes representing the main research emphasis emerged: attitudes towards one's own aging (n = 48), aging well (n = 23), aging stereotypes, self-stigma (n = 23), construction of aging identities (n = 22), subjective age (n = 18), the aging body (n = 8), and future self-views (n = 6). DISCUSSION AND IMPLICATIONS: The research within these themes approach self-perceptions of aging using varying points of reference for what participants compare their age to. The methods used to illicit aging perspectives held their own assumptions about aging.

The experiences of patients and carers living with multimorbid, non-communicable diseases

BACKGROUND: Non-communicable diseases (NCDs) are increasing in prevalence and straining health systems globally. This creates a so-called 'burden of disease', which can be traced in terms of fiscal health system matters and in terms of quality of life and lived experiences of people with NCDs. The United Nations has called for a global agenda to manage NCDs and reduce their burden. OBJECTIVE: The purpose of this article is to summarise key findings from the Serious and Continuing Illness Policy and Practice Study concerning patients’ and carers’ experiences of multimorbid NCDs in Australia. We focus on the relevance of findings for policy and general practitioners in Australia. DISCUSSION: We suggest that a complex multimorbidity policy is needed to contextualise and guide single-illness NCD policies. Our research suggests that specialist NCD nurses and allied health professionals could have important roles in improving care coordination between general practices and community health centres.
