Objective To explore midwives’ experiences of administering sterile water injections (SWI) to labouring women as analgesia for back pain in labour. Design A qualitative study, which generated data through semi-structured focus group interviews with midwives. Data were analysed thematically. Setting Two metropolitan maternity units in Queensland, Australia. Participants Eleven midwives who had administered SWI for back pain in labour in a randomised controlled trial. Findings Three major themes were identified including: i. SWI, is it an intervention?; ii. Tough love, causing pain to relieve pain; iii. The analgesic effect of SWI and impact on midwifery practice. Key conclusions Whilst acknowledging the potential benefits of SWI as an analgesic the midwives in this study described a dilemma between inflicting pain to relieve pain and the challenges encountered in their discussions with women when offering SWI. Midwives also faced conflict when women requested SWI in the face of institutional resistance to its use. Implications for practice The procedural pain associated with SWI may discourage some midwives from offering women the procedure, providing women with accurate information regarding the intensity and the brevity of the injection pain and the expected degree of analgesic would assist in discussion about SWI with women. © 2017 Elsevier Ltd

Objective: to compare the quality of care before and after the introduction of the new Midwifery Group Practice. Design: a cohort study. Setting: the health centers (HCs) in two of the largest remote Aboriginal communities (population 2200-2600) in the Top End of the Northern Territory (NT), each located approximately 500 km from Darwin. The third study site was the Royal Darwin Hospital (RDH) which provides tertiary care. Methods: a 2004-06 retrospective cohort (n=412 maternity cases) provided baseline data. A clinical redesign of maternity services occurring from 2009 onwards focused on increasing Continuity of Carer, Communication, Choice, Collaboration and Co-ordination of Care (5Cs). Data from a 2009-11 prospective cohort (n=310 maternity cases) were collected to evaluate the service redesign. Outcome measures included indicators on the quality of care delivery, adherence to recommended antenatal guidelines and maternal and neonatal health outcomes. Findings: statistically significant improvements were recorded in many areas reflecting improved access to, and quality of, care. For example: fewer women had <4 visits in pregnancy (14% versus 8%), a higher proportion of women had routine antenatal tests recorded (86% versus 97%) and improved screening rates for urine (82% versus 87%) and sexual tract infections (78% versus 93%). However, the treatment of conditions according to recommended guidelines worsened significantly in some areas; for example antibiotics prescribed for urine infections (86% versus 52%) and treatment for anaemia in pregnancy (77% versus 67%). High preterm (21% versus 20%), low birth weight (18% versus 20%) and PPH (29% versus 31%) rates did not change over time. The out of hospital birth rate remained high and unchanged in both cohorts (10% versus 10%). Conclusion: this model addresses some of the disparities in care for remote-dwelling Aboriginal women. However, much work still needs to occur before maternity care and outcomes are equal to that of non-Aboriginal women. Targeted program interventions with stronger clinical governance frameworks to improve the quality of care are essential. A complete rethink of service delivery and engagement may deliver better results. © 2016.

The distribution, phenotype, and requirement of macrophages for fracture-associated inflammation and/or early anabolic progression during endochondral callus formation were investigated. A murine femoral fracture model [internally fixed using a flexible plate (MouseFix)] was used to facilitate reproducible fracture reduction. IHC demonstrated that inflammatory macrophages (F4/80+Mac-2+) were localized with initiating chondrification centers and persisted within granulation tissue at the expanding soft callus front. They were also associated with key events during soft-to-hard callus transition. Resident macrophages (F4/80+Mac-2neg), including osteal macrophages, predominated in the maturing hard callus. Macrophage Fas-induced apoptosis transgenic mice were used to induce macrophage depletion in vivo in the femoral fracture model. Callus formation was completely abolished when macrophage depletion was initiated at the time of surgery and was significantly reduced when depletion was delayed to coincide with initiation of early anabolic phase. Treatment initiating 5 days after fracture with the pro-macrophage cytokine colony stimulating factor-1 significantly enhanced soft callus formation. The data support that inflammatory macrophages were required for initiation of fracture repair, whereas both inflammatory and resident macrophages promoted anabolic mechanisms during endochondral callus formation. Overall, macrophages make substantive and prolonged contributions to fracture healing and can be targeted as a therapeutic approach for enhancing repair mechanisms. Thus, macrophages represent a viable target for the development of pro-anabolic fracture treatments with a potentially broad therapeutic window. © 2014 American Society for Investigative Pathology.

This study investigated staff attitudes, knowledge and use of evidence-based practices (EBP) and links to organisational culture in a community-based autism early intervention service. An EBP questionnaire was completed by 99 metropolitan and regionally-based professional and paraprofessional staff. Participants reported greater knowledge and use of EBPs compared to emerging and unsupported practices. Knowledge and use of EBPs were linked to each other independent of significant correlations with organisational culture and attitudes. Knowledge and use of EBPs was greater in metropolitan than regional locations and paraprofessionals reported greater use of unsupported practices and lower levels of knowledge and use of EBPs than professionals. The implications of these findings for the facilitation of knowledge transfer are discussed. © 2014, Springer Science+Business Media New York.

There is a relative paucity of evidence examining the effectiveness of early intervention for young children with Autism Spectrum Disorder, in particular those delivered through educationally-based programmes. This study aimed to evaluate the real world effectiveness of a community-based autism-specific early learning and intervention programme in Australia. Children enrolled between February 2010 and May 2013 who had a diagnosis of an Autism Spectrum Disorder was eligible to participate in the study. Fifty-nine children with a mean age of 3.98 years participated. Cognitive ability, language, autistic symptoms, and motor skills were assessed at baseline and follow up (12 months or at programme exit) using standardised measures. Pre- and post-measures were compared using paired sample t-tests. Significant improvements were found in receptive and expressive language, autism symptoms, and overall adaptive behaviour. No significant change was found in motor skills. Children with Autism Spectrum Disorder attending the community-based programme had significant gains particularly in domains of cognition and language. Study limitations are discussed. © 2015, International Journal of Special Education. All rights reserved.

Adiponectin is a salutary adipokine and hypoadiponectinemia is implicated in the aetiology of obesity-related inflammation and cardiometabolic disease making therapeutic strategies to increase adiponectin attractive. Emerging evidence, predominantly from preclinical studies, suggests induction of heme-oxygenase-1 (HO-1) increases adiponectin production and reduces inflammatory tone. Here, we aimed to test whether induction of HO-1 enhanced adiponectin production from mature adipocytes. Treatment of human adipocytes with cobalt protoporphyrin (CoPP) or hemin for 24-48 h increased HO-1 expression and activity without affecting adiponectin expression and secretion. Treatment of adipocytes with TNFα reduced adiponectin secretion and increased expression and secretion of additional pro-inflammatory cytokines, IL-6 and MCP-1, as well as expression of sXBP-1, a marker of ER stress. HO-1 induction failed to reverse these effects. These results demonstrate that induction of HO-1 does not directly enhance adiponectin production or ameliorate the pro-inflammatory effects of TNFα and argue against a direct HO-1 - adiponectin axis. © 2015 Elsevier Ireland Ltd.

Objective: to explore back pain in labour from the perspectives of women and midwives. Design: a qualitative study, which generated data through individual semi-structured interviews with postnatal women and focus groups with midwives. Data were analysed thematically. Setting: two metropolitan maternity units in Queensland, Australia. Participants: nine postnatal women and 11 midwives, all of whom had participated in a randomized controlled trial investigating the use of sterile water injections for back pain in labour. Findings: two major themes were identified, including back pain in labour: accounts, rationalisations and coping strategies, and fetal position: destabilising the Occipito Posterior-back pain discourse. Key conclusions: back pain may be severe in labour, may impact negatively upon women's labour and birth experiences, and interfere with their ability to cope as planned. The assumed relationship between fetal position and back pain in labour is a dominant discourse, albeit one which is lacking in empirical credibility. Nonetheless, the information provided to women by maternity professionals tended to reiterate customary practices and beliefs rather than factual knowledge. Increasingly, women refer to other sources, which may challenge the information provided by health professionals. Implications for practice: Back pain in labour is an under-researched area and the lack of solid evidence underpinning the advice provided to women has implications for labour management, and possibly for maternal and fetal outcomes. Care providers might usefully consider back pain as multifactorial, not always associated with OP position, and continue to seek evidence-based management strategies which address women's needs. © 2015 Elsevier Ltd.
