RESUMEN
AIM: One third of Australian children diagnosed with type 1 diabetes present with life-threatening diabetic ketoacidosis (DKA) at diagnosis. Screening for early-stage, presymptomatic type 1 diabetes, with ongoing follow-up, can substantially reduce this risk (<5% risk). Several screening models are being trialled internationally, without consensus on the optimal approach. This pilot study aims to assess three models for a routine, population-wide screening programme in Australia. METHODS: An implementation science-guided pilot study to evaluate the feasibility, acceptability and costs of three screening models in children will be conducted between July 2022 and June 2024. These models are as follows: (1) Genetic risk-stratified screening using newborn heel prick dried bloodspots, followed by autoantibody testing from 11 months of age; (2) genetic risk-stratified screening of infant (6-12 months) saliva followed by autoantibody testing from 10 months of age; and (3) autoantibody screening using capillary dried bloodspots collected from children aged 2, 6 or 10 years. Cohorts for each model will be recruited from targeted geographic areas across Australia involving ≥2 states per cohort, with a recruitment target of up to 3000 children per cohort (total up to 9000 children). The primary outcome is screening uptake for each cohort. Secondary outcomes include programme feasibility, costs, parental anxiety, risk perception, satisfaction, well-being and quality of life, and health professional attitudes and satisfaction. CONCLUSIONS: This pilot is the first direct comparison of three screening implementation models for general population screening. Findings will provide evidence to inform a potential national screening programme for Australian children. TRIAL REGISTRATION: ACTRN12622000381785.
RESUMEN
Tell Kamid el-Loz (Lebanon) was an important Bronze Age urban center that dominated one of the central crossroads of the Ancient Near East, connecting Egypt and the Levant with northern Mesopotamia, Anatolia, and Syria, as well as the interior with the Mediterranean coast. However, by the early Iron Age, the site had shrunk to a small rural settlement. Later, in the Iron Age III / Persian-Hellenistic, only enigmatic pits and a large cemetery remained. In this paper, we analyzed plant micro-remains from the dental calculus of 15 individuals (3 from the Middle Bronze Age II and 12 from the Iron Age III / Persian-Hellenistic) and δ 13C and δ 15N stable isotope data from tbulk bone collagen of 74 individuals (10 from the Middle Bronze Age II and 64 from the Iron Age III / Persian-Hellenistic) and 13 Late Bronze Age animal bones (7 Ovis/Capra and 6 Bos). Our results indicate general stability of human diet throughout the Middle Bronze Age II and the Iron III / Persian-Hellenistic periods, with a reliance on C3 plant crops and terrestrial animals also consuming C3 plants. In the later period, the plant micro-remains indicate the consumption of C4 plants and sedges, and the stable isotope analysis indicates differences in diet between males and females.

RESUMEN
OBJECTIVE: To determine if the relationship between blood pressure (BP) before 16 weeks' gestation and subsequent onset of preeclampsia differs by parity, and by history of hypertensive disorders of pregnancy (HDP) in parous women. STUDY DESIGN: Data from two studies were pooled. First, routinely collected clinical data from three metropolitan hospitals in Sydney, Australia (2017-2020), where BP was measured as part of routine clinical care using validated mercury-free sphygmomanometers. Second, prospectively collected research data from the INTERBIO-21st Study, conducted in six countries, investigating the epidemiology of fetal growth restriction and preterm birth, where BP was measured by dedicated research staff using an automated machine validated for use in pregnancy. MAIN OUTCOME: Adjusted odds ratios (aOR) (95% confidence interval (CI)) for the association of systolic BP (SBP), diastolic BP (DBP) and mean arterial pressure (MAP) with preeclampsia were obtained from logistic regression models. Models were adjusted for age, smoking, body mass index, previous hypertension, previous diabetes, and previous preeclampsia. Interactions for parity, and history of HDP in parous women were included. RESULTS: There were 14,086 pregnancies (Sydney = 11008, INTERBIO-21st = 3078) in the pooled analyses, 6914 (49 %) were parous, of which 414 (6.0 %) had a history of HDP. Nulliparous women had a higher risk of preeclampsia (2.6 %) compared with parous women (1.5 %): [aOR (95 %CI) 3.61 (2.67, 4.94)], as did parous women with a history of HDP (15.0 %) compared with no history (0.7 %) [12.70 (8.02, 20.16)]. MAP before 16 weeks' gestation (mean [SD] 78.8[8.6] mmHg) was more strongly associated than SBP or DBP with development of preeclampsia in parous women [2.22 (1.81, 2.74)] per SD higher MAP] compared with nulliparous women [1.58 (1.34, 1.87)] (p for interaction 0.013). There were no significant differences on the effect of blood pressure on preeclampsia in parous women by history of HDP (p for interaction 0.5465). CONCLUSION: The risk of preeclampsia differs according to parity and history of HDP in a previous pregnancy. Blood pressure in early pregnancy predicts preeclampsia in all groups, although more strongly associated in parous than nulliparous women, but no different in parous women by history of HDP.
RESUMEN
Novel strategies are needed to target the health of postpartum women, who face numerous competing demands. This survey study of 553 postpartum women found 90% want access to a range of health information via social networking sites from reputable professionals, with Instagram (71%) the preferred platform. Delivery of health information to postpartum women via health organisation social networking sites could deliver cost savings and health benefits for postpartum women.
RESUMEN
INTRODUCTION: Hypertensive disorders of pregnancy (HDP) affect up to 10% of all pregnancies annually and are associated with an increased risk of maternal and fetal morbidity and mortality. This guideline represents an update of the Society of Obstetric Medicine of Australia and New Zealand (SOMANZ) guidelines for the management of hypertensive disorders of pregnancy 2014 and has been approved by the National Health and Medical Research Council (NHMRC) under section 14A of the National Health and Medical Research Council Act 1992. In approving the guideline recommendations, NHMRC considers that the guideline meets NHMRC's standard for clinical practice guidelines. MAIN RECOMMENDATIONS: A total of 39 recommendations on screening, preventing, diagnosing and managing HDP, especially preeclampsia, are presented in this guideline. Recommendations are presented as either evidence-based recommendations or practice points. Evidence-based recommendations are presented with the strength of recommendation and quality of evidence. Practice points were generated where there was inadequate evidence to develop specific recommendations and are based on the expertise of the working group. CHANGES IN MANAGEMENT RESULTING FROM THE GUIDELINE: This version of the SOMANZ guideline was developed in an academically robust and rigorous manner and includes recommendations on the use of combined first trimester screening to identify women at risk of developing preeclampsia, 14 pharmacological and two non-pharmacological preventive interventions, clinical use of angiogenic biomarkers and the long term care of women who experience HDP. The guideline also includes six multilingual patient infographics which can be accessed through the main website of the guideline. All measures were taken to ensure that this guideline is applicable and relevant to clinicians and multicultural women in regional and metropolitan settings in Australia and New Zealand.

The human gut microbiome is losing biodiversity, due to the "microbiome modernization process" that occurs with urbanization. To keep track of it, here we applied shotgun metagenomics to the gut microbiome of the Baka, a group of forager-horticulturalists from Cameroon, who combine hunting and gathering with growing a few crops and working for neighboring Bantu-speaking farmers. We analyzed the gut microbiome of individuals with different access to and use of wild plant and processed foods, to explore the variation of their gut microbiome along the cline from hunter-gatherer to agricultural subsistence patterns. We found that 26 species-level genome bins from our cohort were pivotal for the degradation of the wild plant food substrates. These microbes include Old Friend species and are encoded for genes that are no longer present in industrialized gut microbiome. Our results highlight the potential relevance of these genes to human biology and health, in relation to lifestyle.
RESUMEN
OBJECTIVES: To assess the ability of the USCOM® (USCOM), using measurements of cardiac output (CO) and systemic vascular resistance (SVR), to predict the development of pre-eclampsia (PE) and severe PE in hypertensive pregnancies. STUDY DESIGN: Prospective cohort study of women in the second or third trimester recruited at a tertiary center in Sydney, Australia. Demographic data and hemodynamic measurements using the USCOM were taken for all study participants at recruitment. Pregnancy outcome, including development of PE and severe PE, was tracked. Data were analyzed using ANOVA testing, pair-wise comparison testing, and Student's t-testing. RESULTS: Recruitment included 65 normotensive controls, 34 women with chronic hypertension (CH), 51 with gestational hypertension (GH), and 21 with PE. Significantly higher weight, body surface area, and blood pressure measurements were found in the hypertensive, compared with the normotensive control and pregnancies. There were no observed differences in USCOM-measured CO, cardiac index, SVR, or systemic vascular resistance index between hypertensive women who did versus did not develop PE or severe PE in later pregnancy. Analysis of the CH and GH subgroups, as well as only unmedicated hypertensive women (n = 24), also showed no significant difference in hemodynamic parameters between those who did or did not develop PE or severe PE. CONCLUSIONS: Our group was unable to successfully predict the onset of PE or severe PE based on hemodynamic parameters measured with the USCOM. It is possible this relates to the high proportion of women on antihypertensive medication at recruitment.

Women's health has been critically underserved by a failure to look beyond women's sexual and reproductive systems to adequately consider their broader health needs. In almost every country in the world, noncommunicable diseases are the leading causes of death for women. Among these, cardiovascular disease (including heart disease and stroke) and cancer are the major causes of mortality. Risks for these conditions exist at each stage of women's lives, but recognition of the unique needs of women for the prevention and management of noncommunicable diseases is relatively recent and still emerging. Once they are diagnosed, treatments for these diseases are often costly and noncurative. Therefore, we call for a strategic, innovative life-course approach to identifying disease triggers and instigating cost-effective measures to minimize exposure in a timely manner. Prohibitive barriers to implementing this holistic approach to women's health exist in both the social arena and the medical arena. Recognizing these impediments and implementing practical approaches to surmounting them is a rational approach to advancing health equity for women, with ultimate benefits for society as a whole.

BACKGROUND: Postpartum mental illnesses and hypertensive disorders of pregnancy (HDP) are both common, and both associated with adverse maternal and child health outcomes. However, the relationship between them is unclear. This study aimed to investigate prevalence and symptom severity of depression, anxiety, and post-traumatic stress disorder (PTSD) 2-years postpartum in women with normal blood pressure (NBP) during pregnancy versus preeclampsia or gestational hypertension (GH). METHODS: Two-years follow-up of the prospective Postpartum, Physiology, Psychology and Paediatric (P4) Cohort Study was conducted in metropolitan Australia. Prevalence and symptom severity of depression (Edinburgh Postnatal Depression Scale, EPDS > 12), anxiety (7-item Generalized Anxiety Disorder scale, GAD-7 ≥ 10) and PTSD (Posttraumatic stress Diagnostic Scale, PDS/PDS-5) were measured and calculated for women with NBP, preeclampsia and GH. RESULTS: Among 365 participants (NBP: n = 271, preeclampsia: n = 75, GH: n = 19), 2-years postpartum depression prevalence was 3.9% (95% CI 2.3-6.4%): 4.4% after NBP, and 2.7% after preeclampsia (p = 0.53). Anxiety prevalence was higher after GH than NBP (15.8% versus 3.3%, p = 0.02). Prevalence of any mental illness (depression/anxiety/PTSD) was 5.9% (95% CI 3.8-8.8%); 5.6% after NBP, 4.1% after PE, and 15.8% after GH (p = 0.15). Although PTSD prevalence was low (1.4%), and similar between groups (p = 0.97), around 3 times more women after PE (8.1%), compared to NBP (2.5%), recalled childbirth as traumatic (p = 0.003). CONCLUSIONS: Preeclampsia, although associated with persistent perceptions of traumatic childbirth, did not alter the risk of mental illnesses at 2-years postpartum. GH (albeit in a small subgroup) was associated with increased anxiety scores. Larger, multicentre studies are required to clarify relationships between HDP and postpartum mental illness. TRIAL REGISTRATION: Retrospectively registered on 18/11/2013 with the Australian and New Zealand Clinical Trials Registry. REGISTRATION NUMBER: ACTRN 12613 00,126 0718.

BACKGROUND: Increased cardiovascular risk following preeclampsia is well established and there are signs of early cardiovascular aging 6 months postpartum. This study assessed whether blood pressure (BP) and other cardiovascular measures are abnormal 2 years postpartum in the same cohort to determine ongoing risk markers. METHODS: Six months and 2 years postpartum, BP was measured using sphygmomanometry, 24-hour ambulatory BP monitoring, and noninvasive central BP. Anthropometric measures, blood, and urine biochemistry were performed. Cross-sectional comparisons between preeclampsia and normotensive pregnancy (NP) groups and longitudinal comparisons within each group were made at 6 months and 2 years. RESULTS: Two years postpartum, 129 NP, and 52 preeclampsia women were studied who also had 6 months measures. At both time points, preeclampsia group had significantly higher BP (office BP 2 years, 112±12/72±8 versus 104±9/67±7 mmâ Hg NP; [P<0.001]; mean ambulatory BP monitoring 116±9/73±8 versus 106±8/67±6 mmâ Hg NP; [P<0.001]). No significant BP changes noted 6 months to 2 years within either group. Office BP thresholds of 140 mmâ Hg systolic and 90 mmâ Hg diastolic classified 2% preeclampsia and 0% NP at 2 years. American Heart Association 2017 criteria (above normal, >120/80 mmâ Hg) classified 25% versus 8% (P<0.002), as did our reference range threshold of 122/79 mmâ Hg. American Heart Association criteria classified 60% post-preeclampsia versus 16% after NP with above-normal ambulatory BP monitoring (P<0.001). Other cardiovascular risk markers more common 2 years post-preeclampsia included higher body mass index (median 26.6 versus 23.1, P=0.003) and insulin resistance. CONCLUSIONS: After preeclampsia, women have significantly higher BP 6 months and 2 years postpartum, and have higher body mass index and insulin-resistance scores, increasing their future cardiovascular risk. Regular cardiovascular risk screening should be implemented for all who have experienced preeclampsia.

AIMS: The oral glucose tolerance test (OGTT), used for gestational diabetes mellitus (GDM) diagnosis for over 65 years, has poor acceptability and tolerability. Continuous glucose monitoring is being considered as potential alternative. The aim of our study was to formally assess women's and health care professionals' perception of both tests as diagnostic tools for GDM. METHODS: Participants in a pilot study on continuous glucose monitoring for GDM diagnosis were invited to fill two questionnaires, each of 6 Likert-scale and one optional open-ended question. A range of healthcare practitioners were also invited to fill a questionnaire of 13 Likert-scale and 7 optional open-ended questions. RESULTS: Sixty women completed the OGTT and 70 the continuous glucose monitoring questionnaire. OGTT was reported as poorly acceptable. Continuous glucose monitoring was described as significantly more tolerable (81% vs 27% 5/5 general acceptability rate, p < 0.001); ninety-three percent of the participants would recommend it for GDM diagnosis. Thirty health care professionals completed the survey. Most of them (73%) had confidence in OGTT as a diagnostic test for GDM with 66% raising some concerns. Doubts on continuous glucose monitoring were raised in terms of costs, accessibility and accuracy for GDM diagnosis due to "lack of evidence". CONCLUSIONS: Continuous glucose monitoring was substantially better tolerated for women than OGTT. Current lack of evidence for diagnostic accuracy for GDM underlines the need for studies on correlation between continuous glucose monitoring parameters and pregnancy outcomes to strengthen evidence for its use as diagnostic test for GDM.

BACKGROUND: Intrauterine exposure to hypertensive disorders of pregnancy, including gestational hypertension (GH) and preeclampsia (PE), may influence infant growth and have long-term health implications. This study aimed to compare growth outcomes of infants exposed to a normotensive pregnancy (NTP), GH, or PE from birth to 2 years. METHODS: Infants were children of women enroled in the prospective Postpartum Physiology, Psychology and Paediatric (P4) cohort study who had NTP, GH or PE. Birth, 6-month (age-corrected) and 2-year (age-corrected) weight z-scores, change in weight z-scores, rapid weight gain (≥0.67 increase in weight z-score) and conditional weight gain z-scores were calculated to assess infant growth (NTP = 240, GH = 19, PE = 66). RESULTS: Infants exposed to PE compared to NTP or GH had significantly lower birth weight and length z-scores, but there were no differences in growth outcomes at 6 months or 2 years. GH and PE-exposed infants had significantly greater weight z-score gain [95% CI] (PE = 0.93 [0.66-1.18], GH = 1.03 [0.37-1.68], NTP = 0.45 [0.31-0.58], p < 0.01) and rapid weight gain (GH = 63%, PE = 59%, NTP = 42%, p = 0.02) from birth to 2 years, which remained significant for PE-exposed infants after confounder adjustment. CONCLUSION: In this cohort, GH and PE were associated with accelerated infant weight gain that may increase future cardiometabolic disease risk. IMPACT: Preeclampsia exposed infants were smaller at birth, compared with normotensive pregnancy and gestational hypertension exposed infants, but caught up in growth by 2 years of age. Both preeclampsia and gestational hypertension exposed infants had significantly accelerated weight gain from birth to 2 years, which remained significant for preeclampsia exposed infants after adjustment for confounders including small for gestational age. Monitoring of growth patterns in infants born following exposure to a hypertensive disorder of pregnancy may be indicated to prevent accelerated weight gain trajectories and obesity.

INTRODUCTION: Performing surgical procedures is a recognized source of stress for surgeons. Vocational stress is an important contributor to performance, patient care, and burnout with dispositional and environmental factors contributing. Accurately assessing surgeon stress is critical to measuring effectiveness of stress reduction programs. The primary aim was to identify differences between surgeons' self-reported anticipated stress and anxiety prior to gynecological surgery, compared with their recollection of experienced stress and anxiety during surgery. Secondary aims assessed any differences by level of training, surgical type, and surgeon role. MATERIAL AND METHODS: Attending and resident gynecologists performing routine elective surgeries completed a visual analog scale (VAS) assessing perceived stress and the State-Trait Anxiety Inventory (STAI) prior to and immediately after completing 161 elective surgeries including total laparoscopic hysterectomy, laparoscopic excision of moderate-severe endometriosis, or hysteroscopic myomectomy. RESULTS: Eight attending gynecologists and nine residents participated. Residents commenced as primary surgeon in 62/90 (69%) procedures. Stress experienced during surgery was greater than anticipated in 92/161 (57%) surgery episodes (mean VAS increase: 3.9; 95% CI: 1.1-6.8, p = 0.009). State anxiety was greater than anticipated in 99/161 (62%) episodes (mean state anxiety increase: 4.4; 95% CI: 3.0-5.8, p < 0.001). Greater preprocedural anticipatory stress and anxiety was observed in residents vs. attending gynecologists (VAS 51.9 vs. 22.8, p < 0.001; state anxiety 38.3 vs. 28.1, p < 0.001) and in primary vs. assistant surgeons (VAS 47.2 vs. 29.9, p < 0.001; state anxiety 36.9 vs. 28.3, p < 0.001). Intraoperative stress and anxiety were greater in primary surgeons (VAS 50.4 vs. 30.5, p < 0.001; anxiety 41.3 vs. 32.5, p < 0.001) and residents (VAS 43.4 vs. 31.7, p < 0.001; anxiety 53.5 vs. 33.7, p < 0.001) compared with assistants and attending gynecologists. Perceived stress and anxiety were positively correlated at both timepoints (r = 0.68, p < 0.001; r = 0.82, p < 0.001). CONCLUSIONS: When asked to reflect on stress experienced during surgery, our data show that stress during surgery is greater than anticipated for many surgical episodes. Self-reported stress symptoms commence prior to surgery and are more commonly reported by surgeons operating as primary surgeon and by those in training. Future research should focus on determinants of presurgical stress and examine when stressors become inhibitory to performance.

OBJECTIVES: By 2030, 60% of the global population is expected to live in urban areas. Exposure to urban environments during the first 2000 days of life can have positive or negative health outcomes across the life course. Understanding the types of urban exposures that influence health outcomes is needed to guide research priorities for public health and urban planning. This review aims to summarise the published research examining the health outcomes of all urban environmental exposures during the first 2000 days of life, identify the quantity and characteristics of research in this area, methods used, and knowledge gaps. METHODS: We conducted a scoping review using the JBI methodology for scoping reviews. Eight databases were searched for peer-reviewed primary studies. Inclusion criteria were studies that measured maternal, infant and child exposure to everyday urban environment features and conditions in cities/metropolitan areas during the first 2000 days of life and reported offspring health outcomes across the life course, including embryo, fetal/newborn, infant, child, adolescent, and adult outcomes. We used Covidence software for data screening and extraction. Study characteristics and findings were summarised using tables and narrative synthesis. RESULTS: We reviewed 235 articles, which included studies conducted across 41 countries, the majority in the US (n = 63). A broad range of environmental exposures were studied, spanning seven categories: air pollution; energy-based pollution; atmosphere, chemical and metal exposure; neighbourhood-built and natural environment features; neighbourhood community conditions; and residential living conditions. Air pollution was the most studied exposure type (n = 153 studies). Health outcomes were reported for all life stages except adults, with fetal/newborn outcomes the most studied life stage (n = 137). CONCLUSIONS: We found that most research investigating urban environmental exposures in the first 2000 days and health outcomes across the life course focused on air pollution exposures and fetal/newborn health outcomes, using correlational retrospective cohort designs. Few studies included multiple environmental exposures. There is a clear need for more longitudinal research to determine the health impacts of multiple urban environmental exposures across the life course. This will assist in developing urban design and planning strategies and population health to mitigate health risks across the life course.

BACKGROUND: Women from migrant and refugee backgrounds living in high-income countries have increased risk of adverse perinatal outcomes and report lower satisfaction with perinatal healthcare. In Sydney, Australia, a new service known as the Cross Cultural Workers (CCWs) in Maternity and Child and Family Health Service (the CCW Service) was implemented to support such women and families from pregnancy to the early parenting period. This study aimed to ascertain the experiences of women and their partners engaging with the CCW Service. METHODS: A survey study was undertaken. Women accessing the CCW Service were recruited during pregnancy and were asked to complete surveys at three time points: in the third trimester of pregnancy, at 6 and 12 months postpartum. Their partners were invited to complete a survey at 6 months postpartum. Survey data were analysed to compare satisfaction, usefulness, number of CCW interactions, cultural sensitivity, and service improvement recommendations across all three survey timepoints. RESULTS: A total of 231 surveys were received: 113 during pregnancy, 50 at 6-months postpartum, 44 at 12-months postpartum, and 24 partner surveys. Participants in all surveys reported the CCW Service to be useful (84-94%), stating that it increased their understanding of pregnancy, birth and parenting (95-100%), and that they would recommend the CCW Service (92-98%). Participants experienced a high level of satisfaction (88-95%) irrespective of the number of CCW interactions (p = 0.42). Thoughts on becoming a mother or parent were more positive after meeting the CCW than before for both women (p = 0.01) and partners (p = 0.12). Suggestions for CCW Service improvement were to 1) increase the provision of information, specifically financial entitlements, postnatal depression, and support services, 2) increase involvement of partners in care, 3) increase the CCW workforce/or number of CCWs. CONCLUSION: The CCW Service was associated with positive experiences and high rates of satisfaction at all timepoints. This service has the potential to inform the implementation of similar models of care that improve accessibility, the perinatal experience, and respond to the unique needs of women and families from migrant and refugee backgrounds.

The microbiome has emerged as a key determinant of human health and reproduction, with recent evidence suggesting a dysbiotic microbiome is implicated in adverse perinatal health outcomes. The existing research has been limited by the sample collection and timing, cohort design, sample design, and lack of data on the preconception microbiome. This prospective, longitudinal cohort study will recruit 2000 Australian women, in order to fully explore the role of the microbiome in the development of adverse perinatal outcomes. Participants are enrolled for a maximum of 7 years, from 1 year preconception, through to 5 years postpartum. Assessment occurs every three months until pregnancy occurs, then during Trimester 1 (5 + 0-12 + 6 weeks gestation), Trimester 2 (20 + 0-24 + 6 weeks gestation), Trimester 3 (32 + 0-36 + 6 weeks gestation), and postpartum at 1 week, 2 months, 6 months, and then annually from 1 to 5 years. At each assessment, maternal participants self-collect oral, skin, vaginal, urine, and stool samples. Oral, skin, urine, and stool samples will be collected from children. Blood samples will be obtained from maternal participants who can access a study collection center. The measurements taken will include anthropometric, blood pressure, heart rate, and serum hormonal and metabolic parameters. Validated self-report questionnaires will be administered to assess diet, physical activity, mental health, and child developmental milestones. Medications, medical, surgical, obstetric history, the impact of COVID-19, living environments, and pregnancy and child health outcomes will be recorded. Multiomic bioinformatic and statistical analyses will assess the association between participants who developed high-risk and low-risk pregnancies, adverse postnatal conditions, and/or childhood disease, and their microbiome for the different sample types.

PROBLEM: Implementation of woman-centred care in evidence-based maternity practice requires clinicians to be skilled in shared decision-making, yet there is limited training or research into such interventions. BACKGROUND: Shared decision-making enables women to make informed decisions in partnership with clinicians where there are varied clinical options in relation to indications for and timing of planned birth. AIM: We aimed to develop a shared decision-making training intervention and evaluate its feasibility and acceptability to midwives and obstetricians. METHODS: The intervention was co-designed by midwifery and medical clinician-researchers, and a consumer representative. Online training and demonstration videos were distributed to midwives and obstetricians in three Sydney hospitals, followed by two online workshops in 2021 and 2022 where participants practised shared decision-making in roleplaying scenarios tailored to timing of birth. Training was evaluated using post-workshop and post-training surveys and semi-structured qualitative interviews. FINDINGS: The training workshop format, duration and content were well received. Barriers to the uptake of shared decision-making were time, paternalistic practices and fear of repercussions of centring women in the decision-making process. DISCUSSION: The intervention enabled midwifery and medical colleagues to learn communication repertoires from each other in woman-centred discussions around timing of birth. Roleplay scenarios enabled participants to observe and provide feedback on their colleagues' shared decision-making practices, while providing a space for collective reflection on ways to promote, and mitigate barriers to, its implementation in practice. CONCLUSION: Shared decision-making training supports maternity clinicians in developing skills that implement woman-centred care in the timing of planned birth.

Hypertensive disorders of pregnancy (HDP) complicate 5-10% of pregnancies, with resultant lifelong increased risks of cardiovascular disease (CVD). We aimed to describe lifestyle behaviours at 6 months post-HDP in four HDP subgroups, and their association with markers of cardiometabolic health. Subgroups were chronic hypertension (CH), gestational hypertension (GH), preeclampsia, and preeclampsia superimposed on chronic hypertension (CH + PE). The BP2 study is a multi-site, three-arm, randomised controlled trial. At 6 months postpartum, the NSW Population Health Survey and BP2 surveys collected lifestyle behaviours and demographic data. Body mass index (BMI), waist circumference, and blood pressure (BP) were also assessed. Descriptive statistics, ANOVA and Spearman's correlation coefficients were used. Of 484 women (16% CH, 23% GH, 55% preeclampsia, and 6% CH + PE), 62% were overweight or obese. Only 6% met the recommended five vegetable and two fruit serves per day, and 43% did not meet the recommended 150 min of moderate-vigorous physical activity in five sessions per week. Adherence to both diet and physical activity recommendations was correlated with more favourable cardiometabolic outcomes, including lower BMI, waist circumference, and systolic and diastolic BP. Lifestyle interventions that improve diet and physical activity post-HDP are needed to reduce BP, BMI, and long-term CVD in this high-risk population.

STUDY OBJECTIVE: To assess changes in biological measures of acute stress in surgeons during surgery in real-world settings DESIGN: A prospective cohort study. SETTING: A tertiary teaching hospital. PATIENTS: 8 consultant and 9 training gynecologists. INTERVENTION: A total of, 161 elective gynecologic surgeries of 3 procedures: laparoscopic hysterectomy, laparoscopic excision of endometriosis, or hysteroscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: Changes in surgeons' biological measures of acute stress while undertaking elective surgery. Salivary cortisol, mean and maximum heart rate (HR), and indices of the HR variability were recorded before and during surgery. From baseline to during surgery over the cohort, salivary cortisol decreased from 4.1 nmol/L to 3.6 nmol/L (p = .03), maximum HR increased from 101.8 beats per min (bpm) to 106.5 bpm (p <.01), root mean square of standard deviation decreased from 51.1 ms to 39.0 ms (p <.01), and standard deviation of beat-to-beat variability decreased from 73.7 to 59.8 ms (p <.01). Analysis of individual changes in stress by participant-surgery event by paired data graphs reveal inconsistent direction of change in all measures of biological stress despite stratification by surgical experience, role in surgery, level of training, or type of surgery performed. CONCLUSION: This study measured biometric stress changes at both a group and individual level in real-world, live surgical settings. Individual changes have not previously been reported and the variable direction of stress change by participant-surgery episode identified in this study demonstrates a problematic interpretation of mean cohort findings previously reported. Results from this study suggest that either live surgery with tight environment control or surgical simulation studies may identify what, if any, biological measures of stress can predict acute stress reactions during surgery.
RESUMEN
Industrialization-including urbanization, participation in the global food chain and consumption of heavily processed foods-is thought to drive substantial shifts in the human microbiome. While diet strongly influences stool microbiome composition, the influence of diet on the oral microbiome is largely speculative. Multiple ecologically distinct surfaces in the mouth, each harbouring a unique microbial community, pose a challenge to assessing changes in the oral microbiome in the context of industrialization, as the results depend on the oral site under study. Here, we investigated whether microbial communities of dental plaque, the dense biofilm on non-shedding tooth surfaces, are distinctly different across populations with dissimilar subsistence strategies and degree of industrialized market integration. Using a metagenomic approach, we compared the dental plaque microbiomes of Baka foragers and Nzime subsistence agriculturalists in Cameroon (n = 46) with the dental plaque and calculus microbiomes of highly industrialized populations in North America and Europe (n = 38). We found that differences in microbial taxonomic composition between populations were minimal, with high conservation of abundant microbial taxa and no significant differences in microbial diversity related to dietary practices. Instead, we find that the major source of variation in dental plaque microbial species composition is related to tooth location and oxygen availability, which may be influenced by toothbrushing or other dental hygiene measures. Our results support that dental plaque, in contrast to the stool microbiome, maintains an inherent stability against ecological perturbations in the oral environment.
