Young people's experiences with mental health medication: A narrative review of the qualitative literature.

BACKGROUND: With the growing prevalence of mental illness in young people, healthcare professionals require an understanding of the social and psychological implications of medication use in this population. AIM: To characterize the qualitative literature regarding the perceptions and experiences of young people taking medication for mental illness. METHODS: A narrative review of qualitative studies involving young people (13-24 years) taking any medication as treatment for a mental illness. The Medication Experience Model guided analysis of quotes related to medication use. RESULTS: Of the 27 included studies, the majority involved participants with depression and utilized interviews. Young people reported a wide range of mental health medication experiences, both negative and positive, which could influence medication acceptance. Lack of autonomy and the influence of family members were challenges faced by this population. CONCLUSIONS: Young people reported that medications had affected them in various ways across multiple dimensions. Lack of involvement in decision-making and a loss of autonomy were of particular relevance to young people, issues which should also be of interest to healthcare professionals.

Medication management in the context of mental illness: an exploratory study of young people living in Australia.

BACKGROUND: Young people face significant challenges when managing a mental illness, such as acquiring treatment autonomy, being inexperienced users of the healthcare system and associated peer-related stigma. While medication use can be challenging in its own right, there is comparatively little information about the associated experiences and needs of young people with mental illness, particularly in the Australian context. This exploratory study will provide valuable insight into how this group is currently supported in relation to medication use. METHODS: Young people (aged 14-25 years) who had used a prescription medication for any mental illness for a minimum of 2 months were eligible to participate in this qualitative exploratory study. Semi-structured interviews were conducted between October 2017-September 2018 in consultation rooms at two youth-focused mental health support organisations in Brisbane, Queensland. Interview questions explored how participants managed their medication and related experiences. Interviews were transcribed verbatim and descriptively analysed using thematic analysis. RESULTS: Eighteen young people discussed their lived experience during interviews averaging 50 min in duration. Finding the right medication that reduced symptom severity with minimal side-effects was identified as a complex experience for many, particularly when there was a lack of information, support or reduced financial capacity. Young people described a range of strategies to manage medication side-effects, changes and to support routine medication use. CONCLUSIONS: Young people persevered with taking medication to manage a mental illness within a healthcare system that does not adequately support this vulnerable population. There remains a clear directive for healthcare professionals to provide credible information that proactively engages young people as healthcare participants, and for policy makers to consider financial burden for this population with limited financial capacity.

A qualitative study exploring opportunities for pharmacists to connect with young mental health consumers.

OBJECTIVE: To explore how pharmacists can best support young people using medication for any mental health condition. The experiences of obtaining or supplying psychotropic medication and recommendations for service improvement were explored from the perspectives of young people, community pharmacists, and key stakeholders. DESIGN: A qualitative study using semistructured interviews with young people and pharmacists and the nominal group technique as a consensus method for stakeholders. SETTING AND PARTICIPANTS: Face-to-face interviews were conducted with 18 young people and a nominal group with 6 stakeholders at 1 of 2 mental health support organizations in Brisbane, Queensland, Australia. Phone conversations were held with 11 pharmacists who were located across Australia. The young people were aged between 14 and 25 years, had used a mental health medication for the previous 2 months, and lived in the community. Pharmacists recognized as mental health advocates or providing a mental health service and stakeholders from 1 support organization were purposively recruited. OUTCOME MEASURES: Themes related to the current and potential roles for pharmacists when interacting with young people using psychotropic medication. RESULTS: There was limited awareness of the role of pharmacists, possibly because of the largely transactional nature of the young people's pharmacy experiences. However, young people perceived value in receiving information from pharmacists about their psychotropic medication, in particular, their adverse effects, and interactions with alcohol and other recreational drugs. Respectful communication and access to a private space to discuss sensitive matters were ways that pharmacists could encourage the development of supportive relationships with young people. CONCLUSION: This study provides unique insights about the experiences of young people using psychotropic medication within community pharmacies. There is an imperative for pharmacists to move beyond a transactional or reactive approach to create a safe health space and address young people's medication concerns beyond initial supply.

Infant Neurodevelopment is Affected by Prenatal Maternal Stress: The QF2011 Queensland Flood Study.

Research shows that prenatal maternal stress (PNMS) negatively affects a range of infant outcomes; yet no single study has explored the effects of stress in pregnancy from a natural disaster on multiple aspects of infant neurodevelopment. This study examined the effects of flood-related stress in pregnancy on 6-month-olds' neurodevelopment and examined the moderating effects of timing of the stressor in gestation and infant sex on these outcomes. Women exposed to the 2011 Queensland (Australia) floods in pregnancy completed surveys on their flood-related objective and subjective experiences at recruitment and reported on their infants' neurodevelopment on the problem solving, communication, and personal-social scales of the Ages and Stages-III at 6 months postpartum (N = 115). Interaction results showed that subjective flood stress in pregnancy had significantly different effects in boys and girls, and that at high levels of stress girls had significantly lower problem solving scores than boys. Timing of the flood later in pregnancy predicted lower personal-social scores in the sample, and there was a trend (p < .10) for greater objective flood exposure to predict lower scores. PNMS had no effect on infants' communication skills. In conclusion, differential aspects of maternal flood-related stress in pregnancy influenced aspects of 6-month-olds' neurodevelopment.

Service-wide management of healthy gestational weight gain following an implementation science approach.

The aim of health guidelines is to ensure consistency in the delivery of care to minimise health-related complications. However, even when good evidence is available, professionals do not necessarily implement it. Following a 2011 survey (Time 1) of staff in a tertiary maternity hospital, a number of service changes were implemented to facilitate best practice delivery of care to pregnant women regarding gestational weight gain (GWG). A (second) staff survey was then undertaken to re-assess staff knowledge, attitudes and behaviours around the management of GWG in our hospital. This cross-sectional, prospective online survey was distributed to staff in antenatal clinic. The survey assessed staff awareness of pregnancy-related weight complications, knowledge and application of specific guidelines, and a guideline adherence score was calculated. Sixty-nine staff (44.8% response rate) completed the 2014 (Time 2) survey. Just over half (51.9%) stated they were familiar with clinical guidelines regarding weight management in pregnancy. Guideline adherence ranged from 3.7 ± 1.9 to 11.3 ± 1.0 /15 across different professional groups; significant improvements with adherence by dietitians were noted over time. Despite minimal change over time in the overall adherence score, compliance with individual elements of the guideline recommendations comprising the adherence score differed. Improvements in staff practices and attitudes are apparent since the first survey. However, further improvements in guideline awareness and guideline elements are still required to improve the delivery of best practice antenatal GWG care.

Dietary change mediates relationships between stress during pregnancy and infant head circumference measures: the QF2011 study.

Prenatal maternal stress can adversely affect birth outcomes, likely reflecting effects of maternal stress hormones on fetal development. Maternal stress might also induce behavioural changes, such as dietary change, that might influence fetal development. Few studies have documented relationships between stress and dietary change in pregnancy. We analysed stress and dietary change among 222 pregnant women exposed to the 2011 Queensland Floods. We assessed women's objective hardship, subjective distress and cognitive appraisal of the disaster; changes in their diets and their associations with infants' gestational age, weight, length and head circumference at birth, head circumference to birth length ratio (HC/BL) and ponderal index. Greater objective hardship was correlated with more negative dietary change, skipped meals and skipped multivitamins. There were no direct effects of stress or dietary change on birth outcomes. However, we observed an interactive effect of dietary change and exposure timing on head circumference for gestational age (HC for GA) (p = 0.010) and a similar trend for HC/BL (p = 0.064). HC for GA and HC/BL were larger among children whose mothers experienced negative changes to their diet in early pregnancy compared with later pregnancy, consistent with a 'head-sparing' response with early gestation exposure. Further analyses indicated that dietary change mediates the relationship between objective hardship because of the floods and these outcomes. This is the first report of relationships among an independent stressor, dietary change and birth outcomes. It highlights another possible mechanism in the relationship between prenatal maternal stress and child development that could guide future research and interventions.

Aerosol and Surface Deposition Characteristics of Two Surrogates for Bacillus anthracis Spores.

Spores of an acrystalliferous derivative of Bacillus thuringiensis subsp. kurstaki, termed Btcry-, are morphologically, aerodynamically, and structurally indistinguishable from Bacillus anthracis spores. Btcry- spores were dispersed in a large, open-ended barn together with spores of Bacillus atrophaeus subsp. globigii, a historically used surrogate for Bacillus anthracis Spore suspensions (2 × 1012 CFU each of B. atrophaeus subsp. globigii and Btcry-) were aerosolized in each of five spray events using a backpack misting device incorporating an air blower; a wind of 4.9 to 7.6 m s-1 was also flowing through the barn in the same direction. Filter air samplers were situated throughout the barn to assess the aerosol density of the spores during each release. Trays filled with a surfactant in aqueous buffer were placed on the floor near the filter samplers to assess spore deposition. Spores were also recovered from arrays of solid surfaces (concrete, aluminum, and plywood) that had been laid on the floor and set up as a wall at the end of the barn. B. atrophaeus subsp. globigii spores were found to remain airborne for significantly longer periods, and to be deposited on horizontal surfaces at lower densities, than Btcry- spores, particularly near the spray source. There was a 6-fold-higher deposition of Btcry- spores than of B. atrophaeus subsp. globigii spores on vertical surfaces relative to the surrounding airborne density. This work is relevant for selecting the best B. anthracis surrogate for the prediction of human exposure, hazard assessment, and hazard management following a malicious release of B. anthracis IMPORTANCE: There is concern that pathogenic bacteria could be maliciously disseminated in the air to cause human infection and disruption of normal life. The threat from spore-forming organisms, such as the causative agent of anthrax, is particularly serious. In order to assess the extent of this risk, it is important to have a surrogate organism that can be used to replicate the dispersal characteristics of the threat agent accurately. This work compares the aerosol dispersal and deposition behaviors of the surrogates Btcry- and B. atrophaeus subsp. globigii Btcry- spores remained in the air for a shorter time, and were markedly more likely to adhere to vertical surfaces, than B. atrophaeus subsp. globigii spores.

Age-related changes in the effects of stress in pregnancy on infant motor development by maternal report: The Queensland Flood Study.

The current study examined the effects of a natural disaster (a sudden onset flood) as a stressor in pregnancy on infant fine and gross motor development at 2, 6, and 16 months of age. Whether the timing of the stressor in pregnancy or sex of the infant moderated the impact of the prenatal maternal stress on motor development was also explored. Mothers' objective experiences of the flood, emotional reactions and distress, and their cognitive appraisal of the event were assessed retrospectively. Infants' fine and gross motor skills were assessed with the Ages and Stages Questionnaire, and results showed age-related changes in the effects of prenatal maternal stress on these domains. At 2 months, higher levels of prenatal maternal stress was positively related to infant motor development, yet at 6 and 16 months of age there was a negative association, particularly if flood exposure occurred later in pregnancy and if mothers had negative cognitive appraisals of the event. Results also showed differential effects of the maternal stress responses to the floods on infants' fine and gross motor development at each age and that infant sex did not buffer these effects. © 2016 Wiley Periodicals, Inc.

QF2011: a protocol to study the effects of the Queensland flood on pregnant women, their pregnancies, and their children's early development.

BACKGROUND: Retrospective studies suggest that maternal exposure to a severe stressor during pregnancy increases the fetus' risk for a variety of disorders in adulthood. Animal studies testing the fetal programming hypothesis find that maternal glucocorticoids pass through the placenta and alter fetal brain development, particularly the hypothalamic-pituitary-adrenal axis. However, there are no prospective studies of pregnant women exposed to a sudden-onset independent stressor that elucidate the biopsychosocial mechanisms responsible for the wide variety of consequences of prenatal stress seen in human offspring. The aim of the QF2011 Queensland Flood Study is to fill this gap, and to test the buffering effects of Midwifery Group Practice, a form of continuity of maternity care. METHODS/DESIGN: In January 2011 Queensland, Australia had its worst flooding in 30 years. Simultaneously, researchers in Brisbane were collecting psychosocial data on pregnant women for a randomized control trial (the M@NGO Trial) comparing Midwifery Group Practice to standard care. We invited these and other pregnant women to participate in a prospective, longitudinal study of the effects of prenatal maternal stress from the floods on maternal, perinatal and early childhood outcomes. Data collection included assessment of objective hardship and subjective distress from the floods at recruitment and again 12 months post-flood. Biological samples included maternal bloods at 36 weeks pregnancy, umbilical cord, cord blood, and placental tissues at birth. Questionnaires assessing maternal and child outcomes were sent to women at 6 weeks and 6 months postpartum. The protocol includes assessments at 16 months, 2½ and 4 years. Outcomes include maternal psychopathology, and the child's cognitive, behavioral, motor and physical development. Additional biological samples include maternal and child DNA, as well as child testosterone, diurnal and reactive cortisol. DISCUSSION: This prenatal stress study is the first of its kind, and will fill important gaps in the literature. Analyses will determine the extent to which flood exposure influences the maternal biological stress response which may then affect the maternal-placental-fetal axis at the biological, biochemical, and molecular levels, altering fetal development and influencing outcomes in the offspring. The role of Midwifery Group Practice in moderating effects of maternal stress will be tested.

Caseload midwifery care versus standard maternity care for women of any risk: M@NGO, a randomised controlled trial.

BACKGROUND: Women at low risk of pregnancy complications benefit from continuity of midwifery care, but no trial evidence exists for women with identified risk factors. We aimed to assess the clinical and cost outcomes of caseload midwifery care for women irrespective of risk factors. METHODS: In this unblinded, randomised, controlled, parallel-group trial, pregnant women at two metropolitan teaching hospitals in Australia were randomly assigned to either caseload midwifery care or standard maternity care by a telephone-based computer randomisation service. Women aged 18 years and older were eligible if they were less than 24 weeks pregnant at the first booking visit. Those who booked with another care provider, had a multiple pregnancy, or planned to have an elective caesarean section were excluded. Women allocated to caseload care received antenatal, intrapartum, and postnatal care from a named caseload midwife (or back-up caseload midwife). Controls received standard care with rostered midwives in discrete wards or clinics. The participant and the clinician were not masked to assignment. The main primary outcome was the proportion of women who had a caesarean section. The other primary maternal outcomes were the proportions who had an instrumental or unassisted vaginal birth, and the proportion who had epidural analgesia during labour. Primary neonatal outcomes were Apgar scores, preterm birth, and admission to neonatal intensive care. We analysed all outcomes by intention to treat. The trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12609000349246. FINDINGS: Publicly insured women were screened at the participating hospitals between Dec 8, 2008, and May 31, 2011. 1748 pregnant women were randomly assigned, 871 to caseload and 877 to standard care. The proportion of caesarean sections did not differ between the groups (183 [21%] in the caseload group vs 204 [23%] in the standard care group; odds ratio [OR] 0·88, 95% CI 0·70-1·10; p=0·26). The proportion of women who had elective caesarean sections (before onset of labour) differed significantly between caseload and standard care (69 [8%] vs 94 [11%]; OR 0·72, 95% CI 0·52-0·99; p=0·05). Proportions of instrumental birth were similar (172 [20%] vs 171 [19%]; p=0·90), as were the proportions of unassisted vaginal births (487 [56%] vs 454 [52%]; p=0·08) and epidural use (314 [36%] vs 304 [35%]; p=0·54). Neonatal outcomes did not differ between the groups. Total cost of care per woman was AUS$566·74 (95% 106·17-1027·30; p=0·02) less for caseload midwifery than for standard maternity care. INTERPRETATION: Our results show that for women of any risk, caseload midwifery is safe and cost effective. FUNDING: National Health and Medical Research Council (Australia).

Is a randomised controlled trial of a maternity care intervention for pregnant adolescents possible? An Australian feasibility study.

BACKGROUND: The way in which maternity care is provided affects perinatal outcomes for pregnant adolescents; including the likelihood of preterm birth. The study purpose was to assess the feasibility of recruiting pregnant adolescents into a randomised controlled trial, in order to inform the design of an adequately powered trial which could test the effect of caseload midwifery on preterm birth for pregnant adolescents. METHODS: We recruited pregnant adolescents into a feasibility study of a prospective, un-blinded, two-arm, randomised controlled trial of caseload midwifery compared to standard care. We recorded and analysed recruitment data in order to provide estimates to be used in the design of a larger study. RESULTS: The proportion of women aged 15-17 years who were eligible for the study was 34% (n=10), however the proportion who agreed to be randomised was only 11% (n = 1). Barriers to recruitment were restrictive eligibility criteria, unwillingness of hospital staff to assist with recruitment, and unwillingness of pregnant adolescents to have their choice of maternity carer removed through randomisation. CONCLUSIONS: A randomised controlled trial of caseload midwifery care for pregnant adolescents would not be feasible in this setting without modifications to the research protocol. The recruitment plan should maximise opportunities for participation by increasing the upper age limit and enabling women to be recruited at a later gestation. Strategies to engage the support of hospital-employed staff are essential and would require substantial, and ongoing, work. A Zelen method of post-randomisation consent, monetary incentives and 'peer recruiters' could also be considered.

Maternal overweight and obesity: a survey of clinicians' characteristics and attitudes, and their responses to their pregnant clients.

BACKGROUND: Statewide (Queensland) Clinical Guidelines reflecting current best practice have recently become available for the management of pregnancy-related obesity. Our aim was to assess staff knowledge about, adherence to, and characteristics that influence delivery of care according to these Guidelines. METHODS: An online survey, available over a three week period (May-June 2011), was disseminated to obstetric, midwifery and allied health staff working in a tertiary maternity hospital. Outcomes included knowledge of guideline content, advice given, knowledge of obesity pregnancy-related complications, previous training, referral patterns, and staff characteristics, including lifestyle habits, body satisfaction, and Body Mass Index (BMI). RESULTS: Seventy-three staff completed surveys (59.6% response rate). Mean self-reported BMI was 24.2 ± 4.1 kg/m2 (17.9-36.4); 28.5% of staff were overweight (19%) or obese (9.5%), and 27.4% were underweight. However, 28.6%, 2.4%, and 1.2% 'self-classified' themselves as overweight, obese, and underweight, respectively. Almost 40% were dissatisfied/extremely dissatisfied with their weight. While the majority reported overweight/obesity (ow/ob) as an important/very important general obstetric issue and most correctly identified associated perinatal complications, only 32.1% were aware of existing guidelines, with only half correctly identifying BMI categories for ow/ob. A quarter indicated they did not provide women with gestational weight gain (GWG) advice relative to BMI category. Staff identified they would like more training in the area of supporting women to achieve and understand the need for healthy GWG. Staff role was significantly associated with guideline adherence (p=0.03) and association with BMI category approached significance (p=0.07). An association was observed between staff's BMI and their belief in the influence of their advice on women's GWG (p=0.013) and weight satisfaction and belief in women having the resources to make the changes they recommend (p=0.003). CONCLUSIONS: Whilst lack of guideline knowledge provides a barrier to best-practice care, our findings suggest an interplay between staff confidence and personal characteristics in delivering such care which deserves recognition in staff education and training, and service development programs and future research.

The maternal and neonatal outcomes for an urban Indigenous population compared with their non-Indigenous counterparts and a trend analysis over four triennia.

BACKGROUND: Indigenous Australians experience significantly disproportionate poorer health outcomes compared to their non-Indigenous counterparts. Despite the recognised importance of maternal infant health (MIH), there is surprisingly little empirical research to guide service redesign that successfully addresses the disparities. This paper reports on a service evaluation that also compared key MIH indicators for Indigenous and non-Indigenous mothers and babies over a 12-year period 1998-2009. METHODS: Trend analysis with logistic regression, using the independent variables of ethnicity and triennia, explored changes over time (1998-2009) between two cohorts: 1,523 births to Indigenous mothers and 43,693 births to non-Indigenous mothers. We included bivariate and multivariate analysis on key indicators (e.g. teenage births, preterm birth, low birth weight, smoking) and report odds ratios (ORs), 95% CIs and logistic regression adjusting for important confounders. We excluded transfers in from other areas which are identified within the database. RESULTS: Bivariate analysis revealed Indigenous women were statistically more likely to have spontaneous onset of labour and a non-instrumental vaginal birth. They were less likely to take epidurals for pain relief in labour, have assisted births, caesarean sections or perineal trauma. Despite better labour outcomes, Indigenous babies were more likely to be born preterm (< 37 weeks) and be low birth weight (< 2500 g); these differences remained significant in multivariate analysis. The trend analysis revealed relatively stable rates for teenage pregnancy, small for gestational age, low birth weight babies, and perinatal mortality for both cohorts, with the gap between cohorts consistent over time. A statistical widening of the gap in preterm birth and smoking rates was found with preterm birth demonstrating a relative increase of 51% over this period. CONCLUSIONS: The comprehensive database from a large urban hospital allowed a thorough examination of outcomes and contributing factors. The gap between both cohorts remains static in several areas but in some cases worsened. Alternative models for delivering care to Indigenous women and their babies have shown improved outcomes, including preterm birth, though not all have been sustained over time and none are available Australia-wide. New models of care, which recognise the heterogeneity of Indigenous communities, incorporate a multiagency approach, and are set within a research framework, are urgently needed.

Impact on caesarean section rates following injections of sterile water (ICARIS): a multicentre randomised controlled trial.

BACKGROUND: Sterile water injections have been used as an effective intervention for the management of back pain during labour. The objective of the current research is to determine if sterile water injections, as an intervention for back pain in labour, will reduce the intrapartum caesarean section rate. DESIGN: A double blind randomised placebo controlled trialSetting: Maternity hospitals in AustraliaParticipants: 1866 women in labour, ≥18 years of age who have a singleton pregnancy with a fetus in a cephalic presentation at term (between 37 + 0 and 41 + 6 weeks gestation), who assess their back pain as equal to or greater than seven on a visual analogue scale when requesting analgesia and able to provide informed consent. INTERVENTION: Participants will be randomised to receive either 0.1 to 0.3 millilitres of sterile water or a normal saline placebo via four intradermal injections into four anatomical points surrounding the Michaelis' rhomboid over the sacral area. Two injections will be administered over the posterior superior iliac spine (PSIS) and the remaining two at two centimetres posterior, and one centimetre medial to the PSIS respectively. MAIN OUTCOME MEASURE: Proportion of women who have a caesarean section in labour.Randomisation: Permuted blocks stratified by research site.Blinding (masking):Double-blind trial in which participants, clinicians and research staff blinded to group assignment. FUNDING: Funded by the National Health and Medical Research CouncilTrial registration:Australian New Zealand Clinical Trials Registry (No ACTRN12611000221954). DISCUSSION: Sterile water injections, which may have a positive effect on reducing the CS rate, have been shown to be a safe and simple analgesic suitable for most maternity settings. A procedure that could reduce intervention rates without adversely affecting safety for mother and baby would benefit Australian families and taxpayers and would reduce requirements for maternal operating theatre time. Results will have external validity, as the technique may be easily applied to maternity populations outside Australia. In summary, the results of this trial will contribute High level evidence on the impact of SWI on intrapartum CS rates and provide evidence of the analgesic effect of SWI on back pain.

Lost in translation: staff and interpreters' experiences of the edinburgh postnatal depression scale with women from refugee backgrounds.

This paper explores the cross-cultural application of the Edinburgh Postnatal Depression Scale (EPDS) and the difficulties associated with administration to women from refugee backgrounds. Assessing women's comprehension of individual scale items identified problems associated with "Western" terminology and concepts. Re-interpretation of discrete items on the scale was often necessary, raising doubts about the objectivity and reliability of scores. Our findings call for a closer examination of the ethnocentric assumptions underpinning the EPDS items, and the need to incorporate a more diverse range of cross-cultural understandings into future iterations.

Field-based detection of bacteria using nanopore sequencing: Method evaluation for biothreat detection in complex samples.

From pathogen detection to genome or plasmid closure, the utility of the Oxford Nanopore Technologies (ONT) MinION for microbiological analysis has been well documented. The MinION's small footprint, portability, and real-time analytic capability situates it well to address challenges in the field of unbiased pathogen detection, as a component of a security investigation. To this end, a multicenter evaluation of the effect of alternative analytical approaches on the outcome of MinION-based sequencing, using a set of well-characterized samples, was explored in a field-based scenario. Three expert scientific response groups evaluated known bacterial DNA extracts as part of an international first responder (Chemical, Biological, Radiological) training exercise. Samples were prepared independently for analysis using the Rapid and/or Rapid PCR sequencing kits as per the best practices of each of the participating groups. Analyses of sequence data were in turn conducted using varied approaches including ONTs What's in my pot (WIMP) architecture and in-house computational pipelines. Microbial community composition and the ability of each approach to detect pathogens was compared. Each group demonstrated the ability to detect all species present in samples, although several organisms were detected at levels much lower than expected with some organisms even falling below 1% abundance. Several 'contaminant' near neighbor species were also detected, at low abundance. Regardless of the sequencing approach chosen, the observed composition of the bacterial communities diverged from the input composition in each of the analyses, although sequencing conducted using the rapid kit produced the least distortion when compared to PCR-based library preparation methods. One of the participating groups generated drastically lower sequencing output than the other groups, likely attributed to the limited computer hard drive capacity, and occasional disruption of the internet connection. These results provide further consideration for conducting unbiased pathogen identification within a field setting using MinION sequencing. However, the benefits of this approach in providing rapid results and unbiased detection must be considered along with the complexity of sample preparation and data analytics, when compared to more traditional methods. When utilized by trained scientific experts, with appropriate computational resources, the MinION sequencing device is a useful tool for field-based pathogen detection in mixed samples.

The Murri clinic: a comparative retrospective study of an antenatal clinic developed for Aboriginal and Torres Strait Islander women.

BACKGROUND: Indigenous Australians are a small, widely dispersed population. Regarding childbearing women and infants, inequities in service delivery and culturally unsafe services contribute to significantly poorer outcomes, with a lack of high-level research to guide service redesign. This paper reports on an Evaluation of a specialist (Murri) antenatal clinic for Australian Aboriginal and Torres Strait Islander women. METHODS: A triangulated mixed method approach generated and analysed data from a range of sources: individual and focus group interviews; surveys; mother and infant audit data; and routinely collected data. A retrospective analysis compared clinical outcomes of women who attended the Murri clinic (n=367) with Indigenous women attending standard care (n=414) provided by the same hospital over the same period. Both services see women of all risk status. RESULTS: The majority of women attending the Murri clinic reported high levels of satisfaction, specifically with continuity of carer antenatally. However, disappointment with the lack of continuity during labour/birth and postnatally left some women feeling abandoned and uncared for. Compared to Indigenous women attending standard care, those attending the Murri clinic were statistically less likely to be primiparous or partnered, to experience perineal trauma, to have an epidural and to have a baby admitted to the Neonatal Intensive Care Unit, and were more likely to have a non-instrumental vaginal birth. Multivariate analysis found higher normal birth (spontaneous onset of labour, no epidural, non-instrumental vaginal birth without episiotomy) rates amongst women attending the Murri clinic. CONCLUSIONS: Significant benefits were associated with attending the Murri clinic. Recommendations for improvement included ongoing cultural competency training for all hospital staff, reducing duplication of services, improving co-ordination and communication between community and tertiary services, and working in partnership with community-based providers. Combining multi-agency resources to increase continuity of carer, culturally responsive care, and capacity building, including creating opportunities for Indigenous employment, education, and training is desirable, but challenging. Empirical evidence from our Evaluation provided the leverage for a multi-agency agreement to progress this goal within our catchment area.

Overweight and obesity in pregnancy: the evidence-practice gap in staff knowledge, attitudes and practices.

BACKGROUND: Statewide (Queensland) Clinical Guidelines reflecting current best practice have recently become available for the management of pregnancy-related obesity. However, dissemination of guidelines alone do not change practice. AIM: To systematically assess evidence-practice gap in the multidisciplinary management of overweight and obesity (ow/ob) in pregnancy to inform an intervention to facilitate translating obesity guidelines into practice in a tertiary maternity service. MATERIALS AND METHODS: An online survey, available over a three-week period (May-June 2011), was disseminated to obstetric, midwifery and allied health staff. Outcomes of interest included a 15-point guideline adherence score, knowledge of guideline content, advice given, knowledge of obesity-pregnancy-related complications, previous training and referral patterns. RESULTS: Eighty-four staff completed surveys (57% response rate). Widespread discordance with the guideline was noted. The majority (88.1%) reported overweight/obesity (ow/ob) as an important/very important general obstetric issue, most correctly identified associated complications. However, only 32.1% were aware of existing guidelines, with only half correctly identifying BMI categories for ow/ob. Compliance with referral recommendations varied; 20% of staff considered referral 'was not their job'. CONCLUSIONS: Staff are aware of negative outcomes associated with maternal ow/ob, although few are fully compliant with referral guidelines or provide advice in line with recommendations. These findings will be categorised using implementation of science methodological frameworks, and effective behaviour change interventions will be constructed to facilitate translation of this important guideline into practice.

Early Isolates of SARS-CoV-2 Result in Different Pathogenesis in the Transduced Mouse Model of COVID-19.

A transduced mouse model of SARS-CoV-2 infection was established using Balb/c mice. This was achieved through the adenovirus-vectored delivery of the hACE2 gene, to render the mice transiently susceptible to the virus. The model was characterised in terms of the dissemination of hACE2 receptor expression, the dissemination of three SARS-CoV-2 virus variants in vivo up to 10 days following challenge, the resulting histopathology and the clinical signs induced in the mice. In transduced mice, the infection was short-term, with a rapid loss in body weight starting at day 2 with maximum weight loss at day 4, followed by subsequent recovery until day 10. The induced expression of the hACE2 receptor was evident in the lungs, but, upon challenge, the SARS-CoV-2 virus disseminated beyond the lungs to spleen, liver and kidney, peaking at day 2 post infection. However, by day 10 post infection, the virus was undetectable. The lung histopathology was characterised by bronchial and alveolar inflammation, which was still present at day 10 post infection. Transduced mice had differential responses to viral variants ranking CVR-Glasgow 1 > Victoria-1 > England-2 isolates in terms of body weight loss. The transduced mouse model provides a consistent and manipulatable model of SARS-CoV-2 infection to screen viral variants for their relative virulence and possible interventions.
