Effect of brewer's yeast or beta-glucan on breast milk supply following preterm birth: the BLOOM study - protocol for a multicentre randomised controlled trial.

BACKGROUND: Many individuals who experience preterm birth struggle with early breast milk supply, which can translate into suboptimal longer-term breastfeeding outcomes. Further investigations into the potential role of early non-pharmacological and pharmacological interventions in improving breast milk production soon after birth is growing. While natural galactagogues, such as brewer's yeast, are widely perceived by women to be safer than pharmaceutical galactagogues and are taken by many women, evidence to support their efficacy is largely absent. The BLOOM study has been designed to determine the efficacy and safety of brewer's yeast and beta-glucans, derived from Saccharomyces cerevisiae, when administered soon after birth for increasing early breast milk supply in mothers who have delivered preterm. METHODS: The BLOOM study is a multicentre, double-blinded, randomised controlled trial that will assess if brewer's yeast or beta-glucan can increase early breast milk production following preterm birth. Target population are mothers of preterm infants born at less than 34 weeks' gestation who intend to provide breast milk for their infant, are less than 72 h following birth and able to give informed consent. Participants will be randomly allocated into three parallel groups at 1:1:1 ratio (n = 33 per group) to receive either brewer's yeast, beta-glucan or placebo capsules for seven days. The primary outcome is total expressed breast milk volume over a 24-hour period on day 7 of intervention. Participants and their infants will be followed until the infant reaches term corrected age or is discharged home from the neonatal unit (whichever occurs first). DISCUSSION: The use of brewer's yeast as a galactagogue to enhance milk production is extremely common amongst breastfeeding mothers, however, there are no trials evaluating its efficacy and safety. This will be the first randomised controlled trial to evaluate the efficacy and safety of two commonly used galactagogues, brewer's yeast and beta-glucan, compared with placebo in improving maternal breast milk supply following preterm birth. The trial will also evaluate whether early intervention with galactagogues soon after a preterm birth improves longer-term breastfeeding outcomes.

Reducing intravenous antibiotics in neonates born ≥35 weeks' gestation: A quality improvement study.

AIM: To assess the impact of the Early Onset Sepsis (EOS) calculator, implemented as a quality improvement study, to reduce the rate of unnecessary antibiotics in neonates born ≥35 weeks' gestation. METHODS: An audit of routinely collected hospital data from January 2008 to March 2014 (retrospective) and from January 2018 to September 2019 (prospective) determined baseline incidence of EOS intravenous antibiotic use in neonates born ≥35 weeks' gestation in a tertiary level perinatal centre. Plan-do-study-act (PDSA) cycles were applied to implement the EOS calculator. Statistical process control methodology and time series analysis assessments were used to assess the potential impact of the PDSA cycles on the rate of intravenous antibiotics, blood culture collection, EOS, length of stay and health care costs (not adjusted for potential confounders). RESULTS: In the study population, from January 2008 to March 2014, the baseline incidence of intravenous antibiotic use was 10.49% (2970/28290), whilst only 0.067% (19/28290) neonates had culture proven EOS. From January 2018 to October 2019, prior to implementation of the EOS calculator, 13.3% (1119/8411) neonates were treated with intravenous antibiotic and the use decreased to 8.3% (61/734) post-implementation. The rate of blood culture collection decreased from 14.4% (1211/8411) to 11.9% (87/734). There were no cases of missed EOS. Length of stay decreased from 2.68 to 2.39 days, with an estimated cost saving of $366 per patient per admission. CONCLUSION: Implementing the EOS calculator in a tertiary hospital setting reduced invasive investigations for EOS and intravenous antibiotic use among neonates ≥35 weeks' gestation. This can result in reduced length of neonatal hospital stays, and associated health care cost savings and may reduce separation of mother and baby.

Longitudinal trends in uptake of hormonal long-acting reversible contraception devices throughout the COVID-19 pandemic: an Australian population-based study.

BACKGROUND: Little is known about the degree to which the COVID-19 pandemic, and associated restrictions and disruptions to health services, impacted the accessibility of hormonal long-acting reversible contraception (LARC) devices within Australia. Here, we explore longitudinal patterns of dispensing of the contraceptive implant and hormonal intrauterine devices (IUDs) within Australia, before and during the COVID-19 pandemic. METHODS: Population-based cohort study; analysis of 10% random sample of national Pharmaceutical Benefits Scheme dispensing data, for females aged 15-49 years dispensed a hormonal LARC device between February 2017 and November 2021. RESULTS: Interrupted time-series analysis demonstrated overall that there were no significant differences in monthly dispensing rates of hormonal LARC following the Australian onset of the pandemic in April 2020, with no subsequent change in the trend. However, when stratified by LARC type, a significant increase was evident during the pandemic period (April 2020-November 2021) in the rate of hormonal IUD dispensing per month (0.20 per 10 000 95% CI 0.01 to 0.38)), compared with a decrease for the implant (-0.08 per 10 000 (95% CI -0.16 to 0.01)). Increases in hormonal IUD dispensing during the pandemic were most pronounced for those aged 20-24 years, new users, those without a Commonwealth concession card, and in the State of Victoria. CONCLUSIONS: Within Australia in the defined pandemic period, access to hormonal LARC devices was not negatively impacted. Rather a significant increase in dispensing of hormonal IUDs was evident.

Effect of Neonatal Unit Interventions Designed to Increase Breastfeeding in Preterm Infants: An Overview of Systematic Reviews.

INTRODUCTION: This overview aims to systematically review evidence regarding effects of interventions undertaken in neonatal units to increase breastfeeding in preterm infants. METHODS: We followed Cochrane methodology. Systematic reviews published to October 31, 2022, reporting meta-analysis of effects from original studies on breastfeeding rates in preterm infants of neonatal unit interventions designed to increase breastfeeding were included. RESULTS: Avoidance of bottles during breastfeed establishment (comparator breastfeeds with bottle-feeds) demonstrated clear evidence of benefit for any breastfeeding at discharge and exclusive breastfeeding 3 months post-discharge, and possible evidence of benefit for exclusive breastfeeding at discharge, and any breastfeeding post-discharge. Kangaroo mother care (KMC) (comparator usual care) demonstrated clear evidence of benefit for any and exclusive breastfeeding at discharge and possible benefit for any breastfeeding post-discharge. Quality improvement (QI) bundle(s) to enable breastfeeds (comparator conventional care) showed possible evidence of benefit for any breastfeeding at discharge. Cup feeding (comparator other supplemental enteral feeding forms) demonstrated possible evidence of benefit for exclusive breastfeeding at discharge and any breastfeeding 3 months after. Early onset KMC (commenced <24 h post-birth), oral stimulation, and oropharyngeal colostrum administration, showed no evidence of benefit. No meta-analyses reported pooled effects for gestational age or birthweight subgroups. CONCLUSION: There is ample evidence to support investment in KMC, avoidance of bottles during breastfeed establishment, cup feeding, and QI bundles targeted at better supporting breastfeeding in neonatal units to increase prevalence of breastfeeding in preterm infants and promote equal access to breastmilk. Stratifying effects by relevant subgroups is a research priority.

'Like fumbling around in the dark': Young people's perceptions and realities of healthy relationships.

Learning to negotiate relationships is a key feature of adolescence, yet insight into young people's perspectives on what constitutes healthy relationships is lacking. In this study, therefore, insights were sought on healthy relationship qualities, common issues encountered, and relevant educational experiences. Semi-structured interviews were undertaken with 18 young people (11 self-identified as female, 5 male, and 2 trans/gender-diverse) aged 14-20 years, residing in Adelaide, South Australia. Relationships with parents, siblings, peers and intimate partners were topics for discussion. Reflexive thematic analysis was utilised to generate codes and themes. The Five Cs of Positive Youth Development were used to aid understanding of findings. Young people's accounts suggested a disjuncture between desired relationship qualities, realities and education on relationships and sexual health. Young people articulated tensions navigating peer norms and societal expectations in relation to dating and sex, including unrealistic representations, gender stereotyping and strong 'sexpectations'. Participants in this study relied more heavily on personal experience and observation than formal education to develop an understanding of healthy relationships. Achieving healthy relationships was generally perceived to be complex and requiring skills or understanding informants were unsure about. Positive Youth Development could provide a framework for meeting the needs expressed by young people, notably by building communication skills, confidence and agency.

Longitudinal trends in domperidone dispensing to mothers of very preterm infants and its association with breast milk feeding at infant discharge: a retrospective study.

OBJECTIVE: This study aims: (a) to evaluate patterns of domperidone dispensing to mothers of very preterm (<32 weeks gestation) infants born before and after 2014 when international recommendations were made to limit its use and (b) to examine characteristics associated with domperidone dispensing and impacts on breast milk feeding rates at infant hospital discharge. DESIGN: Retrospective audit using linked electronic medical records and hospital pharmacy records. SETTING: Tertiary-referral neonatal intensive care unit at the Women's and Children's Hospital in South Australia. PATIENTS: Mothers of preterm infants admitted to neonatal intensive care from January 2004 to December 2018. MAIN OUTCOME MEASURES: Rate of domperidone dispensing compared pre-2014 and post-2014 recommendations using interrupted time series analyses, and breast milk feeding rates at infant discharge based on domperidone treatment status, adjusted for other factors known to influence breast milk production. RESULTS: Overall, domperidone was dispensed to 691 (41%) of 1688 mothers. Prior to 2014 recommendations, the proportion of women dispensed domperidone was stable. Following the recommendations, there was a significant reduction in trend (-2.55% per half year, 95% CI -4.57% to -0.53%;), reflecting less domperidone dispensing.Breast milk feeding rates at discharge remained consistently lower in infants of women dispensed domperidone than those who were not (adjusted OR 0.58, 95% CI 0.45 to 0.75). CONCLUSION: Domperidone dispensing in mothers of hospitalised very preterm infants has declined over time following international regulatory warnings. Breast milk feeding rates remain lower in mothers prescribed domperidone, suggesting further research is needed to optimise lactation support for mothers of very preterm infants.

Online platforms for prescription and supply of hormonal contraception in Australia: a mapping review.

Online platforms have emerged as a convenient way for individuals to access contraception. However, the extent to which such services exist in Australia and how they operate is currently unknown. We aimed to identify Australian online contraception platforms and evaluate the services they provide to determine the degree to which they may facilitate equitable access to contraception. We conducted an internet search to identify online contraception platforms operating in Australia. Data were extracted from each of the platforms relating to operating policies, services provided and associated payment processes, as well as prescribing and screening processes for assessing user suitability. As of July 2022, eight online contraception platforms operating within Australia were identified. All platforms offered oral contraception, with two also offering the vaginal ring, and one emergency oral contraception. None of the platforms provided access to long-acting reversible contraception. Significant variability existed in product and membership costs across platforms, with only one platform providing access to subsidised medicines. Five platforms restricted services to those already using oral contraception. Overall, online questionnaires were deemed to be adequately screening for important contraindications to using oral contraception. While online contraception platforms may be a valuable option for some individuals who face access barriers and are willing to pay out-of-pocket for to have their contraception sent straight to their home, they do not necessarily ensure that individuals can access their contraceptive method of choice or address recognised financial and structural barriers to contraceptive care.

Women's experiences with using domperidone as a galactagogue to increase breast milk supply: an australian cross-sectional survey.

BACKGROUND: Domperidone is one of the most commonly utilised pharmacological galactagogues, with evidence of increasing use in clinical practice. However, the use of domperidone as a galactagogue remains controversial, with mixed evidence on safety and efficacy, leading to variable clinical practice recommendations. We sought to evaluate contemporary patterns of domperidone use and examine maternal experiences related to perceived safety and effectiveness. METHODS: In 2019, we conducted an online, cross-sectional survey of Australian breastfeeding women to examine individual experiences related to domperidone use, in addition to perceptions of safety and effectiveness. RESULTS: Among 1876 survey responses, 19% (n = 355) reported using domperidone. Domperidone use was significantly higher in women who were primiparous, gave birth preterm, delivered by caesarean section, had self-perceived low milk supply, and saw a lactation consultant. Nearly 20% of women commenced domperidone use in the first week postpartum (19%, n = 67). The median duration of use was six weeks (interquartile range 3-16 weeks). Maximum reported doses of domperidone used ranged from 20 mg/day to 160 mg/day. Half (n = 178, 50%) of women reported using a dose of 30 mg/day or less, 44% (n = 155) reported using a dose between 31 and 60 mg/day, and 6% (n = 22) reported using a dose greater than 61 mg/day. Nearly half of the respondents reported domperidone as 'very' or 'extremely effective' (45%, n = 161), with only 8% (n = 27) reporting it was 'not at all effective'. Almost half (n = 172, 48%) of all women using domperidone reported side effects, including weight gain (25%), headaches (17%) and dry mouth (13%). Higher doses were associated with an increased likelihood of any side effects (≤ 30 mg/day, 38%; >31-≤60 mg/day, 48%, > 61 mg/day 73%; P < 0.004), with 31 (9%) stopping domperidone because of side effects. CONCLUSION: We identified widespread variation in domperidone utilisation patterns, with domperidone broadly perceived to be effective in increasing breast milk supply. Side effects associated with domperidone treatment were common, appeared to be dose-related, and were frequently associated with treatment cessation. These findings highlight the importance of improved clinical practice recommendations and generation of evidence from additional high-quality clinical trials evaluating the efficacy and safety of domperidone. More conclusive clinical trials are needed to determine the efficacy, as well as optimal dose and duration, of domperidone use.

Family planning and multiple sclerosis: A qualitative study of patient experiences to understand information needs and promote informed decision-making.

OBJECTIVES: Ambiguity exists about the impact of multiple sclerosis (MS) on fertility and pregnancy. We explored female and male patients' experiences with MS regarding family planning to understand information needs and opportunities to improve informed decision-making. METHODS: Semi-structured interviews were conducted with Australian female (n = 19) and male (n = 3) patients of reproductive age diagnosed with MS. Transcripts were analysed thematically, adopting a phenomenological approach. RESULTS: Four main themes emerged: 'reproductive planning', revealing inconsistent experiences about pregnancy intention discussions with health care professionals (HCPs), and involvement in decisions about MS management and pregnancy; 'reproductive concerns', about the impact of the disease and its management; 'information awareness and accessibility', with participants generally reporting they had limited access to desired information and received conflicting information about family planning; and 'trust and emotional support', with continuity of care and engagement with peer-support groups about family planning needs valued. CONCLUSION: Patients with MS want consistent engagement with HCPs regarding discussion of pregnancy intent and desire improvements in quality and accessibility of available resources and support services to address reproductive concerns. PRACTICE IMPLICATIONS: Family planning conversations should be a part of routine care planning for MS patients and contemporary resources are required to support these discussions.

Breastfeeding outcomes in late preterm infants: A multi-centre prospective cohort study.

OBJECTIVES: To describe (1) infant feeding practices during initial hospitalisation and up to 6 months corrected age (CA) in infants born late preterm with mothers intending to breastfeed, (2) the impact of early feeding practices on hospital length of stay and (3) maternal and infant factors associated with duration of breastfeeding. METHODS: We conducted a prospective cohort study of infants born at 34+0 to 36+6 weeks gestational age during 2018-2020. Families were followed up until the infant reached 6 months of age (corrected for prematurity). Feeding practices during the birth hospitalisation, length of initial hospital stay, and the prevalence of exclusive or any breastfeeding at 6 weeks, 3 months, and 6 months CA were examined. Associations between maternal and infant characteristics and breastfeeding at 6 weeks, 3 months and 6 months CA were assessed using multivariable logistic regression models. RESULTS: 270 infants were enrolled, of these, 30% were multiple births. Overall, 78% of infants received only breastmilk as their first feed, and 83% received formula during the hospitalisation. Seventy-four per cent of infants were exclusively breastfed at discharge, 41% at 6 weeks CA, 35% at 3 months CA, and 29% at 6 months CA. The corresponding combined exclusive and partial breastfeeding rates (any breastfeeding) were 72%, 64%, and 53% of babies at 6 weeks CA, 3 months CA, and 6 months CA, respectively. The mean duration of hospitalisation was 2.9 days longer (95% confidence interval (CI) 0.31, 5.43 days) in infants who received any formula compared with those receiving only breastmilk (adjusted for GA, maternal age, multiple birth, site, and neonatal intensive care unit admission). In multivariable models, receipt of formula as the first milk feed was associated with a reduction in exclusive breastfeeding at 6 weeks CA (odds ratio = 0.22; 95% CI 0.09 to 0.53) and intention to breastfeed >6 months with an increase (odds ratio = 4.98; 95% CI 2.39 to 10.40). Intention to breastfeed >6 months remained an important predictor of exclusive breastfeeding at 3 and 6 months CA. CONCLUSIONS: Our study demonstrates that long-term exclusive breastfeeding rates were low in a cohort of women intending to provide breastmilk to their late preterm infants, with approximately half providing any breastmilk at 6 months CA. Formula as the first milk feed and intention to breastfeed >6 months were significant predictors of breastfeeding duration. Improving breastfeeding outcomes may require strategies to support early lactation and a better understanding of the ongoing support needs of this population.

Associations of Maternal Milk Feeding With Neurodevelopmental Outcomes at 7 Years of Age in Former Preterm Infants.

Importance: Maternal milk feeding may have unique long-term neurodevelopmental benefits in very preterm infants. Objective: To examine the extent to which maternal milk feeding after very preterm birth is associated with cognitive, academic, and behavioral outcomes at school age. Design, Setting, and Participants: This prospective cohort study assessed 586 infants born at less than 33 weeks' gestation at 5 Australian perinatal centers and enrolled in the Docosahexaenoic Acid for Improvement of Neurodevelopmental Outcomes study (January 1, 2001, to December 31, 2005) who were evaluated at a corrected age of 7 years. The statistical analysis was completed on January 19, 2022. Exposures: Maternal milk intake, including mean volume (milliliters per kilogram per day) during neonatal hospitalization and total duration (in months). Main Outcomes and Measures: Neurodevelopmental outcomes at 7 years of age were (1) IQ (Wechsler Abbreviated Scale of Intelligence), (2) academic achievement (Wide Range Achievement Test, Fourth Edition), (3) symptoms of attention-deficit/hyperactivity disorder (ADHD) (Conners Third Edition ADHD Index, parent reported), (4) executive function (Behavior Rating Inventory of Executive Functioning, parent reported), and (5) behavior (Strengths and Difficulties Questionnaire, parent reported). Results: A total of 586 infants (mean [SD] gestational age at birth, 29.6 [2.3] weeks; 314 male [53.6%]) born to 486 mothers (mean [SD] age, 30.6 [5.5] years; 447 [92.0%] White) were included. Mean (SD) maternal milk intake in the neonatal intensive care unit was 99 (48) mL/kg daily, and mean (SD) maternal milk duration was 5.1 (5.4) months. Mean (SD) full-scale IQ was 98.5 (13.3) points. After covariate adjustment, higher maternal milk intake during the neonatal hospitalization was associated with higher performance IQ (0.67 points per additional 25 mL/kg daily; 95% CI, 0.10-1.23 points), reading scores (1.14 points per 25 mL/kg daily; 95% CI, 0.39-1.89 points), and math scores (0.76 points per 25 mL/kg daily; 95% CI, 0.14-1.37 points) and fewer ADHD symptoms (-1.08 points per 25 mL/kg daily; 95% CI, -1.96 to -0.20 points). Longer duration of maternal milk intake was associated with higher reading (0.33 points per additional month; 95% CI, 0.03-0.63 points), spelling (0.31 points per month; 95% CI, 0.01-0.62 points), and math (0.30 points per month; 95% CI, 0.03-0.58 points) scores. Maternal milk was not associated with improved full-scale IQ, verbal IQ, executive function, or behavior. Most associations were stronger among infants born at lower gestational ages, particularly less than 30 weeks (interaction P values <.01). Conclusions and Relevance: In this cohort study of preterm infants, maternal milk feeding during the neonatal hospitalization and after discharge were associated with better school-age performance IQ and academic achievement and with a reduction in ADHD symptoms, particularly among infants born at less than 30 weeks' gestation.

Reflexive Practice as an Approach to Improve Healthcare Delivery for Indigenous Peoples: A Systematic Critical Synthesis and Exploration of the Cultural Safety Education Literature.

Cultural safety is increasingly being taught in tertiary programmes of study for health professionals. Reflexivity is a key skill required to engage in culturally safe practice, however, there is currently limited literature examining how reflexivity is taught or assessed within cultural safety curricula. A systematic review of the literature up until November 2021 was conducted, examining educational interventions which aimed to produce culturally safe learners. Studies were limited to those with a focus on Indigenous health and delivered in Australia, Aotearoa New Zealand, Canada, and the United States. A total of 46 documents describing 43 different educational interventions were identified. We found that definitions and conceptualisations of reflexivity varied considerably, resulting in a lack of conceptual clarity. Reflexive catalysts were the primary pedagogical approaches used, where objects, people, or Indigenous pedagogies provided a counterpoint to learners' knowledges and experiences. Information regarding assessment methods was limited but indicates that the focus of existing programmes has been on changes in learner knowledge and attitudes rather than the ability to engage in reflexivity. The results demonstrate a need for greater conceptual clarity regarding reflexivity as it relates to cultural safety, and to develop methods of assessment that focus on process rather than outcomes.

Knowledge of Galactagogue Use During Breastfeeding in Australia: A Cross Sectional Online Survey.

BACKGROUND: Galactagogues have been used for centuries to induce, maintain, or increase a mother's milk supply. Recently, there has been an apparent increase in utilization and promotion of galactagogues, largely in the absence of data regarding their efficacy and safety. However, there is limited contemporary evidence about knowledge of these substances in the community or how and where individuals seek information. RESEARCH AIM: To evaluate knowledge about galactagogue use during breastfeeding among birth parents, including recognition of specific substances, perceptions of safety, and common information sources. METHOD: An online, prospective, cross-sectional survey of Australian birthing parents (N = 2055) who were currently breastfeeding or had previously breastfed their infants was conducted from September to December 2019. The survey included questions about recognition of galactagogues, perceptions of safety, and information-seeking behaviors. RESULTS: Among participants, 47% (n = 882) were primiparous and 65% (n = 1,219) were currently breastfeeding. The most recognized galactagogues included lactation cookies (89%; n = 1,828), brewer's yeast (79%; n = 1,629), fenugreek (74%; n = 1,519), and domperidone (69%; n = 1,420). Respondents cited the internet (52%; n = 1,066), lactation support providers (46%; n = 951), midwives (42%; n = 873), general practitioners (39%; n = 802), and social media (35%; n = 714) as common information sources. Lactation support providers and breastfeeding helplines were commonly rated as helpful; whereas, general practitioners and community pharmacists were often rated as unhelpful. While most participants perceived galactagogues to be safe, herbal or dietary galactagogues were perceived to be safer than pharmaceutical galactagogues. CONCLUSIONS: Our Australian community survey of individuals with current or previous breastfeeding experience identified widespread recognition of galactagogue use, with participants reporting a broad range of information-seeking behaviors and generally perceiving galactagogues as being safe to use.

Association between self-reported periodontitis and high-risk oral human papillomavirus infection among Indigenous South Australians: A cross-sectional study.

INTRODUCTION: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing globally, reflecting an increase in human papillomavirus (HPV)-related lesions. Indigenous populations are disproportionately affected by OPSCCs. Currently, testing for oral HPV is not recommended as a screening tool to permit early detection of OPSCCs due to the high population prevalence of HPV infection. Periodontitis may be a marker of oral HPV infection, but previous research evaluating this association has been inconclusive. Here we report a large population-based study examining the association between high-risk oral HPV infection and periodontitis among Indigenous South Australians. METHODS: We utilised a large convenience sample of Indigenous South Australians aged 18+ years recruited between February 2018 and February 2020. Of the original cohort (n = 1011), 748 (73.9%) participants participated in the 12 month follow-up. Detailed information on sociodemographic characteristics, health-related behaviours, and sexual history were collected at enrolment. Saliva samples were collected at 12 months and tested for the presence of oral HPV DNA using the optimized general primer (GP) + PCR system. The primary outcomes were the prevalence of any high-risk oral HPV DNA, and separately, HPV 16 and/or 18. Periodontitis was assessed at follow-up by using validated self-reported periodontitis screening questions. Logistic regression analyses were undertaken to assess the association between self-reported periodontitis and oral HPV infection with adjustment for potential sociodemographic and behavioural confounders, with estimates presented as odds ratios (OR) and 95% confidence interval (CI). RESULTS: Data on 673 participants (89.9% of the follow-up cohort) were available. Participants ranged in age from 18 to 80 (mean age 42.2, SD 14.7) and 31.5% were male. Overall, 115 (17.1%) participants had self-reported periodontitis, 40 (5.9%) had any high-risk oral HPV and 14 (2.1%) had HPV 16 and/or 18. Any high-risk HPV was detected among seven (17.5%) participants and HPV 16 and/or 18 was detected in three (21.4%) who self-reported periodontitis. In the regression analyses no significant association was found between self-reported periodontitis and high-risk oral HPV (adjusted OR: 1.10; 95% CI: 0.45-2.70) or HPV 16 and/or 18 (adjusted OR: 1.27; 95% CI: 0.32-5.03). CONCLUSION: This study did not find any association between self-reported periodontitis and high-risk oral HPV among Indigenous South Australians. Further targeted studies with standardized clinical measures of periodontal disease are needed to clarify the link between high-risk oral HPV and periodontal disease. If confirmed this would add further weight to the importance of recommendations about the utility of periodontitis screening to identify individuals at risk of carrying high-risk oral HPV, who may benefit from more intensive screening and ongoing monitoring.

Antenatal magnesium sulphate for preventing cerebral palsy: An economic evaluation of the impact of a quality improvement program.

Previous work demonstrated that implementing a quality improvement (QI) program improves the uptake of guideline-recommended antenatal magnesium sulphate, a critical intervention known to reduce cerebral palsy risk. Here we estimate potential cost savings attributable to the improved uptake. By expanding coverage from 63 to 83% of eligible women, we estimated that five children potentially would not have received a diagnosis of cerebral palsy, a potential cost saving of $AU4.8 million in lifetime healthcare costs. Our findings strengthen the case for embedding QI approaches in perinatal care to reduce the incidence of cerebral palsy.

Antenatal magnesium sulfate to prevent cerebral palsy.

Magnesium sulfate given to women before birth at <30 weeks' gestation reduces the risk of cerebral palsy in their children. Our study aimed to assess the impact of a local quality improvement programme, primarily using plan-do-study-act cycles, to increase the use of antenatal magnesium sulfate. After implementing our quality improvement programme, an average of 86% of babies delivered at <30 weeks' gestation were exposed to antenatal magnesium sulfate compared with a historical baseline rate of 63%. Our study strengthens the case for embedding quality improvement programmes in maternal perinatal care to reduce the impact of cerebral palsy on families and society.

Dispensing of clomiphene citrate to treat infertility: medication supplied and population prevalence of assisted pregnancies and multiple births.

OBJECTIVE: To determine the proportion of pregnancies resulting in birth that were conceived with the use of clomiphene citrate (CC) and the frequency of multiple pregnancy. DESIGN: Whole-of-population cohort study, constructed through data linkage. Comprehensive Australian Government records of dispensed medications were linked to state Perinatal Registry records for all births of at least 20 weeks' gestation. SETTING: The state of South Australia. PATIENT(S): Women who maintained pregnancy for at least 20 weeks and gave birth between July 2003 and December 2015, a total of 150,713 women with 241,561 pregnancies. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Ongoing pregnancy occurring in proximity to CC, defined as dispensing from 90 days before to the end of a conception window derived from newborn date of birth and gestational age. RESULT(S): Linkage to dispensed prescription records was achieved for 97.9% of women. Women who conceived with CC tended to be older and socioeconomically advantaged and more likely than other women to have a history of miscarriage. Ongoing pregnancies associated with CC comprised 1.6% of the total; 5.7% were multiple births (mostly twins, 94.6%) compared with 1.5% in the remainder (98.5% twins). CONCLUSION(S): In South Australia, 1.6% of pregnancies (1 in 60) of at least 20 weeks' gestation were conceived proximal to CC dispensing. Of these, 5.7% were multiple pregnancies. This takes the proportion of women who achieved an ongoing pregnancy with medical assistance from 4.4%, based on reports from assisted reproductive technology clinics, to 6% in total.

"Fear of stopping" vs "wanting to get off the medication": exploring women's experiences of using domperidone as a galactagogue - a qualitative study.

BACKGROUND: Domperidone is the most frequently prescribed medicine used to increase breast milk supply. There is considerable controversy surrounding the use of domperidone in lactation, due to limited evidence about efficacy and concerns about rare but life-threatening side-effects. Despite this, in many high-income settings such as Australia, use of domperidone among breastfeeding mothers appears to be increasing. The aim of this paper was to explore women's experiences of using domperidone during breastfeeding. METHODS: Semi-structured interviews were conducted in 2019 with 15 women in Australia who reported using domperidone as a galactagogue during breastfeeding. Interviews were recorded, transcribed and analysed thematically. RESULTS: Women reported a wide variety of practices concerning the timing of initiation of domperidone use, including prophylactic use, as well as the dose and duration of use. Prolonged periods of use and unsupervised dosing were commonly reported, these practices were sometimes associated with a fear of the consequences of stopping, insufficient provision of information about the drug or feeling dismissed by health professionals. Some women indicated that when doctors refused to prescribe domperidone they responded by doctor shopping and seeking anecdotal information about benefits and risks online, leading to unsupervised practices. Women often reported high expectations surrounding the effectiveness of domperidone, and most used the medication in conjunction with food/herbal galactagogues and non-galactagogue support. Positive outcomes following domperidone use included having greater confidence in breastfeeding and pride at achieving breastfeeding goals. CONCLUSIONS: This study identified a variety of practices concerning domperidone use, including potentially unsafe practices, linked in some cases to inconsistent advice from health professionals and a reliance on online, anecdotal information sources. These findings emphasise the urgent need for development of clinical practice guidelines and a greater focus on translating existing evidence concerning domperidone into clinical practice, including clinical support that is tailored to women's needs.
