RESUMO

Interleukin-7 (IL-7) supports the growth and chemoresistance of T-cell acute lymphoblastic leukemia (T-ALL), particularly the early T-cell precursor subtype (ETP-ALL), which frequently has activating mutations of IL-7 signaling. Signal transducer and activator of transcription (STAT5) is an attractive therapeutic target because it is almost universally activated in ETP-ALL, even in the absence of mutations of upstream activators such as the IL-7 receptor (IL-7R), Janus kinase, and Fms-like tyrosine kinase 3 (FLT3). To examine the role of activated STAT5 in ETP-ALL, we have used a Lmo2-transgenic (Lmo2Tg) mouse model in which we can monitor chemoresistant preleukemia stem cells (pre-LSCs) and leukemia stem cells (LSCs) that drive T-ALL development and relapse following chemotherapy. Using IL-7R-deficient Lmo2Tg mice, we show that IL-7 signaling was not required for the formation of pre-LSCs but essential for their expansion and clonal evolution into LSCs to generate T-ALL. Activated STAT5B was sufficient for the development of T-ALL in IL-7R-deficient Lmo2Tg mice, indicating that inhibition of STAT5 is required to block the supportive signals provided by IL-7. To further understand the role of activated STAT5 in LSCs of ETP-ALL, we developed a new transgenic mouse that enables T-cell specific and doxycycline-inducible expression of the constitutively activated STAT5B1∗6 mutant. Expression of STAT5B1∗6 in T cells had no effect alone but promoted expansion and chemoresistance of LSCs in Lmo2Tg mice. Pharmacologic inhibition of STAT5 with pimozide-induced differentiation and loss of LSCs, while enhancing response to chemotherapy. Furthermore, pimozide significantly reduced leukemia burden in vivo and overcame chemoresistance of patient-derived ETP-ALL xenografts. Overall, our results demonstrate that STAT5 is an attractive therapeutic target for eradicating LSCs in ETP-ALL.

RESUMO

BACKGROUND: Perinatal mental health disorders affect up to 20% of all women. Women of refugee background are likely to be at increased risk, yet little research has explored this. This study aimed to assess if women of refugee background are more likely to screen risk positive for depression and anxiety than non-refugee women, using the Edinburgh Postnatal Depression Scale (EPDS); and if screening in pregnancy using the EPDS enables better detection of depression and anxiety symptoms in women of refugee background than routine care. METHODS: This implementation study was conducted at an antenatal clinic in Melbourne, Australia. Women of refugee and non-refugee backgrounds were screened for depression using English or translated versions of the EPDS and a psychosocial assessment on a digital platform. The psychosocial assessment records of 34 women of refugee background receiving routine care (no screening) were audited. RESULTS: Overall, 274 women completed the EPDS; 43% of refugee background. A similar proportion of women of refugee and non-refugee backgrounds had EPDS scores of ≥9 (39% vs. 40% p = 0.93). Women receiving the combined EPDS and psychosocial screening were more likely to receive a referral for further support than women receiving routine care (41% vs. 18%, p = 0.012). CONCLUSION: Similarly, high proportions of women of refugee and non-refugee backgrounds were at increased risk of experiencing a current depressive disorder in early pregnancy, suggesting pregnancy care systems should acknowledge and respond to the mental health needs of these women. Screening appeared to facilitate the identification and referral of women compared to routine care.

RESUMO

PURPOSE: This systematic review aimed to determine if digital screening for mental health in pregnancy and postpartum is acceptable, feasible and more effective than standard care (paper-and pen-based screening or no screening). The second aim was to identify barriers and enablers to implementing digital screening in pregnancy and postpartum. METHOD: OVID MEDLINE, PsycINFO, SCOPUS, CINAHL, Embase, Web of Science, Joanna Briggs Database and All EMB reviews incorporating Cochrane Database of Systematic Reviews (OVID) were systematically searched for articles that evaluated digital screening for mental health in pregnancy and postpartum between 2000 and 2021. Qualitative articles were deductively mapped to the Theoretical Domains Framework (TDF). RESULTS: A total of 34 articles were included in the analysis, including qualitative, quantitative and mixed-methods studies. Digital screening was deemed acceptable, feasible and effective. TDF domains for common barriers included environmental context and resources, skills, social/professional role and identity and beliefs about consequences. TDF domains for common enablers included knowledge, social influences, emotion and behavioural regulation. CONCLUSION: When planning to implement digital screening, consideration should be made to have adequate training, education and manageable workload for healthcare professionals (HCP's). Organisational resources and support are important, as well as the choice of the appropriate digital screening assessment and application setting for women. Theory-informed recommendations are provided for both healthcare professionals and women to inform future clinical practice.

RESUMO

PURPOSE: We previously developed a novel functional benchtop apparatus to simulate catheter occlusion in vitro utilizing avian vitelline membrane and chalaza to test catheter designs and de-obstruction techniques. Here, we study the integration of double-lumen catheter-mediated backflow in the shunt system assembly and its potential for an in-line de-obstruction of an obstructed ventricular catheter. METHODS: A double-lumen catheter was connected to a standard proximal shunt catheter for all trials. One limb of the double-lumen catheter was connected to the backflow mechanisms and allowed to loop back for fluid access. A micropump and a bi-corporal electromagnetic pump were utilized to provide various degrees of backflow at predetermined intervals. Flow rates were measured after initial occlusion and after implementation of the backflow mechanisms, and degrees of catheter blockage was calculated as a percentage of the unoccluded flow rate. Flow visualization was also used. RESULTS: In baseline blockage of less than 50%, the average occluding agent weighed 0.3-0.6 g with baseline flow rates of 8.5-11.9 mL/min. After 5 min of backflow using a micropump, the degree of blockage was reduced in 50% of trials. Additional backflow for 5 min did not provide further improvements in flow rate. In baseline blockage of greater than 50%, the average occluding agent weighed 0.8-1.3 g with baseline flow rates of 1.1-4.2 mL/min. After 5 min of backflow, the system demonstrated a decreased blockage in 20% of trials; additional backflow for 5 min further improved the flow rate in 40% of the total trials. Only magnetic plates provided enough force to provide pulsatile backflow in the bi-corporal electromagnetic system. CONCLUSIONS: The preliminary results of connecting a standard proximal catheter in series with a double-lumen catheter show a slight change in the percent occlusion from the baseline status several times when the retrograde flow occurred via one limb of the catheter. Additionally, the de-obstruction seems related to the length of the interval of the backflow and the initial percentage occlusion of the proximal catheter. The statistical analysis does not reveal a statistically significant reduction in occlusion in the proximal catheter with either backflow interval.

RESUMO

In 2021, the Preconception Health Network Australia co-developed preconception health core indicators identified as critical to ensuring optimal maternal and child outcomes following conception. We conducted an audit of perinatal databases across each state and territory to identify whether preconception core indicator data were available. Seven health domains co-developed by the Preconception Health Network were mapped against the data collected in the perinatal databases. Indicator data were lacking across all seven health domains, with data missing for social determinants of health indicators. Better data linkage and developing a national evidence-based framework would allow ongoing monitoring of women's preconception health nationally.

RESUMO

AIMS/HYPOTHESIS: The aim of this work was to investigate the risk of developing chronic kidney disease (CKD) or end-stage kidney disease (ESKD) following a pregnancy complicated by gestational diabetes mellitus (GDM) or pre-existing diabetes among Aboriginal women in the Northern Territory (NT), Australia. METHODS: We undertook a longitudinal study of linked healthcare datasets. All Aboriginal women who gave birth between 2000 and 2016 were eligible for inclusion. Diabetes status in the index pregnancy was as recorded in the NT Perinatal Data Collection. Outcomes included any stage of CKD and ESKD as defined by ICD-10 coding in the NT Hospital Inpatient Activity dataset between 2000 and 2018. Risk was compared using Cox proportional hazards regression. RESULTS: Among 10,508 Aboriginal women, the mean age was 23.1 (SD 6.1) years; 731 (7.0%) had GDM and 239 (2.3%) had pre-existing diabetes in pregnancy. Median follow-up was 12.1 years. Compared with women with no diabetes during pregnancy, women with GDM had increased risk of CKD (9.2% vs 2.2%, adjusted HR 5.2 [95% CI 3.9, 7.1]) and ESKD (2.4% vs 0.4%, adjusted HR 10.8 [95% CI 5.6, 20.8]). Among women with pre-existing diabetes in pregnancy, 29.1% developed CKD (adjusted HR 10.9 [95% CI 7.7, 15.4]) and 9.9% developed ESKD (adjusted HR 28.0 [95% CI 13.4, 58.6]). CONCLUSIONS/INTERPRETATION: Aboriginal women in the NT with GDM or pre-existing diabetes during pregnancy are at high risk of developing CKD and ESKD. Pregnancy presents an important opportunity to identify kidney disease risk. Strategies to prevent kidney disease and address the social determinants of health are needed.

RESUMO

BACKGROUND: In-utero hyperglycemia exposure influences later cardiometabolic risk, although few studies include women with pre-existing type 2 diabetes (T2D) or assess maternal body mass index (BMI) as a potential confounder. OBJECTIVE: To explore the association of maternal T2D and gestational diabetes mellitus (GDM) with childhood anthropometry, and the influence of maternal BMI on these associations. METHODS: The PANDORA cohort comprises women (n = 1138) and children (n = 1163). Women with GDM and T2D were recruited from a hyperglycemia in pregnancy register, and women with normoglycemia from the community. Wave 1 follow-up included 423 children, aged 1.5-5 years (median follow-up age 2.5 years). Multivariable linear regression assessed associations between maternal antenatal variables, including BMI and glycemic status, with offspring anthropometry (weight, height, BMI, skinfold thicknesses, waist, arm and head circumferences). RESULTS: Greater maternal antenatal BMI was associated with increased anthropometric measures in offspring independent of maternal glycemic status. After adjustment, including for maternal BMI, children exposed to maternal GDM had lower mean weight (-0.54 kg, 95% CI: -0.99, -0.11), BMI (-0.55 kg/m2, 95% CI: -0.91, -0.20), head (-0.52 cm, 95% CI: -0.88, -0.16) and mid-upper arm (-0.32 cm, 95% CI: -0.63, -0.01) circumferences, and greater mean suprailiac skinfold (0.78 mm, 95% CI: 0.13, 1.43), compared to children exposed to normoglycemia. Adjustment for maternal BMI strengthened the negative association between GDM and child weight, BMI and circumferences. Children exposed to maternal T2D had smaller mean head circumference (-0.82 cm, 95% CI: -1.33, -0.31) than children exposed to normoglycemia. Maternal T2D was no longer associated with greater child mean skinfolds (p = 0.14) or waist circumference (p = 0.18) after adjustment for maternal BMI. CONCLUSIONS: Children exposed to GDM had greater suprailiac skinfold thickness than unexposed children, despite having lower mean weight, BMI and mid-upper arm circumference, and both GDM and T2D were associated with smaller mean head circumference. Future research should assess whether childhood anthropometric differences influence lifetime cardiometabolic and neurodevelopmental risk.

RESUMO

STUDY QUESTION: What is the recommended assessment and management of those with polycystic ovary syndrome (PCOS), based on the best available evidence, clinical expertise, and consumer preference? SUMMARY ANSWER: International evidence-based guidelines address prioritized questions and outcomes and include 254 recommendations and practice points, to promote consistent, evidence-based care and improve the experience and health outcomes in PCOS. WHAT IS KNOWN ALREADY: The 2018 International PCOS Guideline was independently evaluated as high quality and integrated multidisciplinary and consumer perspectives from six continents; it is now used in 196 countries and is widely cited. It was based on best available, but generally very low to low quality, evidence. It applied robust methodological processes and addressed shared priorities. The guideline transitioned from consensus based to evidence-based diagnostic criteria and enhanced accuracy of diagnosis, whilst promoting consistency of care. However, diagnosis is still delayed, the needs of those with PCOS are not being adequately met, evidence quality was low and evidence-practice gaps persist. STUDY DESIGN, SIZE, DURATION: The 2023 International Evidence-based Guideline update reengaged the 2018 network across professional societies and consumer organizations, with multidisciplinary experts and women with PCOS directly involved at all stages. Extensive evidence synthesis was completed. Appraisal of Guidelines for Research and Evaluation-II (AGREEII)-compliant processes were followed. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework was applied across evidence quality, feasibility, acceptability, cost, implementation and ultimately recommendation strength and diversity and inclusion were considered throughout. PARTICIPANTS/MATERIALS, SETTING, METHODS: This summary should be read in conjunction with the full Guideline for detailed participants and methods. Governance included a six-continent international advisory and management committee, five guideline development groups, and paediatric, consumer, and translation committees. Extensive consumer engagement and guideline experts informed the update scope and priorities. Engaged international society-nominated panels included paediatrics, endocrinology, gynaecology, primary care, reproductive endocrinology, obstetrics, psychiatry, psychology, dietetics, exercise physiology, obesity care, public health and other experts, alongside consumers, project management, evidence synthesis, statisticians and translation experts. Thirty-nine professional and consumer organizations covering 71 countries engaged in the process. Twenty meetings and five face-to-face forums over 12 months addressed 58 prioritized clinical questions involving 52 systematic and 3 narrative reviews. Evidence-based recommendations were developed and approved via consensus across five guideline panels, modified based on international feedback and peer review, independently reviewed for methodological rigour, and approved by the Australian Government National Health and Medical Research Council (NHMRC). MAIN RESULTS AND THE ROLE OF CHANCE: The evidence in the assessment and management of PCOS has generally improved in the past five years, but remains of low to moderate quality. The technical evidence report and analyses (∼6000 pages) underpins 77 evidence-based and 54 consensus recommendations, with 123 practice points. Key updates include: i) further refinement of individual diagnostic criteria, a simplified diagnostic algorithm and inclusion of anti-Müllerian hormone (AMH) levels as an alternative to ultrasound in adults only; ii) strengthening recognition of broader features of PCOS including metabolic risk factors, cardiovascular disease, sleep apnea, very high prevalence of psychological features, and high risk status for adverse outcomes during pregnancy; iii) emphasizing the poorly recognized, diverse burden of disease and the need for greater healthcare professional education, evidence-based patient information, improved models of care and shared decision making to improve patient experience, alongside greater research; iv) maintained emphasis on healthy lifestyle, emotional wellbeing and quality of life, with awareness and consideration of weight stigma; and v) emphasizing evidence-based medical therapy and cheaper and safer fertility management. LIMITATIONS, REASONS FOR CAUTION: Overall, recommendations are strengthened and evidence is improved, but remains generally low to moderate quality. Significantly greater research is now needed in this neglected, yet common condition. Regional health system variation was considered and acknowledged, with a further process for guideline and translation resource adaptation provided. WIDER IMPLICATIONS OF THE FINDINGS: The 2023 International Guideline for the Assessment and Management of PCOS provides clinicians and patients with clear advice on best practice, based on the best available evidence, expert multidisciplinary input and consumer preferences. Research recommendations have been generated and a comprehensive multifaceted dissemination and translation program supports the Guideline with an integrated evaluation program. STUDY FUNDING/COMPETING INTEREST(S): This effort was primarily funded by the Australian Government via the National Health Medical Research Council (NHMRC) (APP1171592), supported by a partnership with American Society for Reproductive Medicine, Endocrine Society, European Society for Human Reproduction and Embryology, and European Society for Endocrinology. The Commonwealth Government of Australia also supported Guideline translation through the Medical Research Future Fund (MRFCRI000266). HJT and AM are funded by NHMRC fellowships. JT is funded by a Royal Australasian College of Physicians (RACP) fellowship. Guideline development group members were volunteers. Travel expenses were covered by the partnering organizations.

RESUMO

AIMS: To determine rates and predictors of postpartum diabetes screening among Aboriginal and/or Torres Strait Islander and non-Indigenous women with gestational diabetes mellitus (GDM). METHODS: PANDORA is a prospective longitudinal cohort of women recruited in pregnancy. Postpartum diabetes screening rates at 12 weeks (75-g oral glucose tolerance test (OGTT)) and 6, 12 and 18 months (OGTT, glycated haemoglobin [HbA1C ] or fasting plasma glucose) were assessed for women with GDM (n = 712). Associations between antenatal factors and screening with any test (OGTT, HbA1C , fasting plasma glucose) by 6 months postpartum were examined using Cox proportional hazards regression. RESULTS: Postpartum screening rates with an OGTT by 12 weeks and 6 months postpartum were lower among Aboriginal and/or Torres Strait Islander women than non-Indigenous women (18% vs. 30% at 12 weeks, and 23% vs. 37% at 6 months, p < 0.001). Aboriginal and/or Torres Strait Islander women were more likely to have completed a 6-month HbA1C compared to non-Indigenous women (16% vs. 2%, p < 0.001). Screening by 6 months postpartum with any test was 41% for Aboriginal and/or Torres Strait Islander women and 45% for non-Indigenous women (p = 0.304). Characteristics associated with higher screening rates with any test by 6 months postpartum included, insulin use in pregnancy, first pregnancy, not smoking and lower BMI. CONCLUSIONS: Given very high rates of type 2 diabetes among Aboriginal and Torres Strait Islander women, early postpartum screening with the most feasible test should be prioritised to detect prediabetes and diabetes for intervention.

RESUMO

AIMS: The COVID-19 pandemic necessitated the rapid change in a dedicated multidisciplinary menopause clinic from in-person consultations to telehealth. The aim of this study was to explore the impact of COVID-19 on menopause service delivery and consumer experiences. METHODS: Two-part study involving the following. (i) Clinical audit conducted June-July 2019 (pre-COVID-19) and June-July 2020 (COVID-19) assessing practice and service delivery changes. Assessment outcomes included: patient demographics, cause of menopause, presence of menopause symptoms, appointment attendance, medical history, investigations and menopause treatments. (ii) A post-clinic online survey exploring the acceptability and experience of telehealth, once telehealth models of care had been routinely used in the menopause service (2021). RESULTS: Pre-COVID (n = 156) and COVID-19 (n = 150) clinic consultations were audited. Menopause care delivery changed significantly from 100% face-to-face consultations in 2019 to 95.4% telehealth consultations in 2020. In 2020, fewer women had investigations performed vs 2019 (P < 0.001), although use of menopausal therapies was similar (P < 0.05). Ninety-four women completed the online survey. Most women (70%) were satisfied with their telehealth consultation and perceived that the doctor effectively communicated with them (76%). Women preferred face-to-face consultations for their first menopause clinic visit (69%) and telehealth for review consultations (65%). The majority of women (62%) viewed the continuation of telehealth consultations as 'moderately' to 'extremely useful' post-pandemic. CONCLUSION: The COVID-19 pandemic caused significant changes to menopause service delivery. Telehealth was perceived as feasible and acceptable by women, supporting the continuation of a hybrid service delivery model incorporating telehealth and face-to-face consultation to meet the needs of women.

RESUMO

ISSUE ADDRESSED: The preconception period provides opportunities for health behaviour optimisation for improved maternal and child well-being. However, preconception information sources women engage with are not well-known. METHODS: To address this gap, the current cross-sectional study retrospectively explored (1) preconception information or advice accessed on recommended preconception health topics and (2) preferred sources of preconception information amongst pregnant women receiving care through Australian public and private maternity settings. RESULTS: Overall, 78% of women reported accessing any preconception health information, predominantly concerning achieving/maintaining a healthy weight, diet, folic acid and multivitamin supplementation. Preferred information sources included health professionals, e.g. general practitioners (74%) and the internet (66%), although source engagement varied. CONCLUSIONS: Whilst women predominantly prefer seeking preconception health information from health professionals and the internet, multi-modal resources are needed to reach women and enhance engagement with evidence-based information and healthcare in preparation for pregnancy. SO WHAT?: Evaluation of preconception health resources for women and health professionals is warranted, appraising their adequacy in supporting engagement with key preconception health messages. In particular, assessment of the quality, readability and evidence-base of online resources is needed. Our findings highlight the need for public health experts to take action to raise awareness amongst women of the importance of preconception health, encourage health professional engagement for preconception care and direct women to more appropriate evidence-based online resources.

RESUMO

Polycystic ovary syndrome (PCOS) is associated with a higher risk for pregnancy and birth complications according to the specific features associated with PCOS. The features include obesity before and during pregnancy, hyperandrogenism, insulin resistance, infertility, cardiometabolic risk factors, and poor mental health. PCOS is not often recognized as a risk factor for poor pregnancy and birth outcomes in pregnancy care guidelines, while its associated features are. Pregnancy-related risk profile should ideally be assessed for modifiable risk factors (e.g., lifestyle and weight management) at preconception in women with PCOS. Hyperglycaemia should be screened using a 75-g oral glucose tolerance test at preconception or within the first 20 weeks of pregnancy if it has not been performed at preconception and should be repeated at 24-28 weeks of pregnancy. In the absence of evidence of benefit for strategies specific to women with PCOS, the international evidence-based guidelines for the assessment and management of PCOS recommend screening, optimizing, and monitoring risk profile in women with PCOS (at preconception, during and postpregnancy) consistent with the recommendations for the general population. Recommended factors include blood glucose, weight, blood pressure, smoking, alcohol, diet, exercise, sleep and mental health, emotional, and sexual health among women with PCOS. The guidelines recommend Metformin in addition to lifestyle for assisting with weight management and improving cardiometabolic risk factors, particularly in those with overweight or obesity. Letrozole is considered the first-line pharmacological treatment for anovulatory infertility in PCOS. Individualized approach should be considered in the management of pregnancy in PCOS.

RESUMO

AIMS: Women with prior gestational diabetes have nearly 10 times the risk of developing type 2 diabetes. Postpartum screening for type 2 diabetes is recommended for early diagnosis and management, yet uptake is low. This work updates a previous systematic review and advances it through the application of the Theoretical Domains Framework (TDF) to synthesise personal-level factors impacting type 2 diabetes screening and the Capability, Opportunity, Motivation-Behaviour model (COM-B), to develop messaging recommendations for use in clinical practice and screening promotion interventions. METHODS: We searched seven academic databases from September 2017 (prior review) to April 2021, reference lists and grey literature. Two reviewers independently screened articles against inclusion criteria (qualitative studies exploring factors impacting postpartum diabetes screening, any language) and extracted data. Using an inductive-deductive model, we coded determinants to the TDF and mapped onto the COM-B model. RESULTS: We identified 38 eligible papers from 34 studies (N = 1291 participants). Most (71%) reported sample sizes of N ≥ 16. The ratio of barriers to enablers was three to one. Eight key TDF domains were identified. Evidence-based recommendations include addressing knowledge, risk perception, fear of diabetes diagnosis, low prioritisation of personal health and fatalism. The risk of bias was low and confidence in findings was moderate to high. A limitation was conceptual overlap between TDF domains, which we addressed via the study procedure. CONCLUSIONS: The theoretical categorisation of determinants enables the development of messaging and interventions at the personal level, to promote women's uptake of postpartum type 2 diabetes screening.

RESUMO

AIMS: Racial and ethnic disparities exist in gestational diabetes prevalence and risk of subsequent type 2 diabetes mellitus (T2DM). Postpartum engagement in healthy behaviours is recommended for prevention and early detection of T2DM, yet uptake is low among women from diverse cultural backgrounds. Greater understanding of factors impacting postpartum health behaviours is needed. Applying the Theoretical Domains Framework (TDF) and Capability, Opportunity, Motivation-Behaviour (COM-B) model, our aim was to synthesise barriers to and enablers of postpartum health behaviours among women from diverse cultural backgrounds with prior GDM and identify relevant intervention components. METHODS: Databases, reference lists and grey literature were searched from September 2017 to April 2021. Two reviewers screened articles independently against inclusion criteria and extracted data. Using an inductive-deductive model, themes were mapped to the TDF and COM-B model. RESULTS: After screening 5148 citations and 139 full texts, we included 35 studies (N = 787 participants). The main ethnicities included Asian (43%), Indigenous (15%) and African (11%). Barriers and enablers focused on Capability (e.g. knowledge), Opportunity (e.g. competing demands, social support from family, friends and healthcare professionals, culturally appropriate education and resources) and Motivation (e.g. negative emotions, perceived consequences and necessity of health behaviours, social/cultural identity). Five relevant intervention functions are identified to link the barriers and enablers to evidence-based recommendations for communications to support behaviour change. CONCLUSIONS: We provide a conceptual model to inform recommendations regarding the development of messaging and interventions to support women from diverse cultural backgrounds in engaging in healthy behaviours to reduce risk of T2DM.

RESUMO

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.

RESUMO

The aim of this study was to investigate symptomatology and diagnoses of PTSD and subthreshold PTSD and the screening properties of the Harvard Trauma Questionnaire (HTQ) within a sample of Dari-speaking women of refugee background receiving antenatal care. This cross-sectional study administered the HTQ to 52 Dari-speaking women at a public pregnancy clinic. The trauma module from the Structured Clinical Interview (SCID-5) was administered. Interview material was presented to an expert panel, blinded to the HTQ screening results, in order to achieve consensus diagnoses of PTSD using Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) criteria. Three women (5.8%) met DSM-5 criteria for PTSD. Eleven women (21.15%) met criteria for subthreshold PTSD, defined as meeting two or three of the DSM-5 criteria domains. A comparison of HTQ cut-off scores was conducted and a score of ≥ 2.25 on the HTQ demonstrated excellent sensitivity 1.00 (95% CI 0.29-1.00) and specificity 0.76 (95% CI 0.61-0.87) in detecting PTSD; however, a wide confidence interval for sensitivity was found. A cut-off score of ≥ 2 provided the best balance of sensitivity 1.00 (95% CI 0.72-1.00) and specificity 0.80 (95% CI 0.65-0.91) when assessing for subthreshold PTSD. Screening for perinatal PTSD for women of refugee background is recommended, in order to identify those at risk of DSM diagnosis and also those women experiencing distressing PTSD symptomatology.

RESUMO

BACKGROUND: Pregnancy is a time of increased risk for developing or re-experiencing mental illness. Perinatal mental health screening for all women is recommended in many national guidelines, but a number of systems-level and individual barriers often hinder policy implementation. These barriers result in missed opportunities for detection and early intervention and are likely to be experienced disproportionately by women from culturally and linguistically diverse backgrounds, including women of refugee backgrounds. The objectives of this study were to develop a theory-informed, evidence-based guide for introducing and integrating perinatal mental health screening across health settings and to synthesize the learnings from an implementation initiative and multisectoral partnership between the Centre of Perinatal Excellence (COPE), and a university-based research centre. COPE is a nongovernmental organization (NGO) commissioned to update the Australian perinatal mental health guidelines, train health professionals and implement digital screening. METHODS: In this case study, barriers to implementation were prospectively identified and strategies to overcome them were developed. A pilot perinatal screening programme for depression and anxiety with a strong health equity focus was implemented and evaluated at a large public maternity service delivering care to a culturally diverse population of women in metropolitan Melbourne, Australia, including women of refugee background. Strategies that were identified preimplementation and postevaluation were mapped to theoretical frameworks. An implementation guide was developed to support future policy, planning and decision-making by healthcare organizations. RESULTS: Using a behavioural change framework (Capability, Opportunity, Motivation-Behaviour Model), the key barriers, processes and outcomes are described for a real-world example designed to maximize accessibility, feasibility and acceptability. A Programme Logic Model was developed to demonstrate the relationships of the inputs, which included stakeholder consultation, resource development and a digital screening platform, with the outcomes of the programme. A seven-stage implementation guide is presented for use in a range of healthcare settings. CONCLUSIONS: These findings describe an equity-informed, evidence-based approach that can be used by healthcare organizations to address common systems and individual-level barriers to implement perinatal depression and anxiety screening guidelines. PATIENT OR PUBLIC CONTRIBUTION: These results present strategies that were informed by prior research involving patients and staff from a large public antenatal clinic in Melbourne, Australia. This involved interviews with health professionals from the clinic such as midwives, obstetricians, perinatal mental health and refugee health experts and interpreters. Interviews were also conducted with women of refugee background who were attending the clinic for antenatal care. A steering committee was formed to facilitate the implementation of the perinatal mental health screening programme comprising staff from key hospital departments, GP liaison, refugee health and well-being, the NGO COPE and academic experts in psychology, midwifery, obstetrics and public health. This committee met fortnightly for 2 years to devise strategies to address the barriers, implement and evaluate the programme. A community advisory group was also formed that involved women from eight different countries, some of refugee background, who had recently given birth at the health service. This committee met bimonthly and was instrumental in planning the implementation and evaluation such as recruitment strategies, resources and facilitating an understanding of the cultural complexity of the women participating in the study.

RESUMO

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.

RESUMO

OBJECTIVE: Identifying women at risk of depression and anxiety during pregnancy provides an opportunity to improve health outcomes for women and their children. One barrier to screening is the availability of validated measures in the woman's language. Afghanistan is one of the largest source countries for refugees yet there is no validated measure in Dari to screen for symptoms of perinatal depression and anxiety. The aim of this study was to assess the screening properties of a Dari translation of the Edinburgh Postnatal Depression Scale. METHODS: This cross-sectional study administered the Edinburgh Postnatal Depression Scale Dari version to 52 Dari-speaking women at a public pregnancy clinic in Melbourne, Australia. A clinical interview using the depressive and anxiety disorders modules from the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) was also conducted. Interview material was presented to an expert panel to achieve consensus diagnoses. The interview and diagnostic process was undertaken blind to Edinburgh Postnatal Depression Scale screening results. RESULTS: Cronbach's alpha coefficient for the Edinburgh Postnatal Depression Scale Dari version was good (α = 0.79). Criterion validity was assessed using the receiver operating characteristics curve and generated excellent classification accuracy for depression diagnosis (0.90; 95% confidence interval [0.82, 0.99]) and for anxiety diagnosis (0.94; 95% confidence interval [0.88, 1.00]). For depression, a cut-off score of 9, as recommended for culturally and linguistically diverse groups, demonstrated high sensitivity (1.00; 95% confidence interval [0.79, 1.00]) and specificity (0.88; 95% confidence interval [0.73, 0.97]). For anxiety, a cut-off score of ⩾5 provided the best balance of sensitivity (1.00; 95% confidence interval [0.72, 1.00]) and specificity (0.80; 95% confidence interval [0.65, 0.91]). CONCLUSION: These results support the use of this Edinburgh Postnatal Depression Scale Dari version to screen for symptoms of depression and anxiety during pregnancy as well as the use of a lowered cut-off score.
