Out of home care for children in Australia: a review of literature and policy

The aims of the study were to review trends in out-of-home care, both in the numbers of children being placed in different types of care in Australia and in the ways of organising and supporting such care that are emerging in different national and State contexts. The study also involved identifying emerging models of care and the drivers of change, and reviewing evidence on the outcomes of different models. The research involved a review of recent literature from Australia and the main English-speaking countries overseas; analysis of policy documents relating to fostering and kinship care in the states and territories of Australia; and informal discussions with policy informants and practitioners in Australia and overseas

Policy representation of everyday harm experienced by people with disability

People with disability are at heightened risk of violence, abuse, neglect and exploitation (VANE) with policy geared towards responding to and eliminating VANE harm. Yet not all harm experienced by people with disability is captured within the VANE harm. Many people also experience harm in everyday interactions that leave them feeling uncomfortable, devalued, disrespected, threatened or silenced. Our multi-method study begins with the term ‘everyday harm’ to describe these subtle, difficult-to-define and easily overlooked experiences, with the proviso that a more appropriate vocabulary may emerge from subsequent fieldwork. This article presents the results of a policy review about the representation of everyday harm between people with disability and paid support workers in disability policies. Results show that everyday harm is acknowledged in some disability policies. However, this acknowledgement is neither consistent nor comprehensive and policies do not consider the cumulative impact of everyday harm nor the subjective experience of harm. This review suggests a gap in conceptualising this type of harm and having a vocabulary that people with disability, support workers and organisations can use to acknowledge, name and, ultimately, prevent this form of harm. Empirical research about their experience of everyday harm is needed to address this gap

Providing Explainable Race-Time Predictions and Training Plan Recommendations to Marathon Runners

The Fourteenth ACM Conference on Recommender Systems (RecSys '20), Rio de Janeiro (held online due to coronavirus outbreak), 22- 26 September 2020Millions of people participate in marathon events every year, typically devoting at least 12-16 weeks to building their endurance and fitness so that they can safely complete these gruelling 42.2km races. Most runners follow a training plan that is tailored to their expected finish-time (e.g. sub-4 hours or 4-5 hours), and these plans will prescribe a complex mixture of training sessions to help them achieve these times. However, such plans cannot adapt to the individual needs (fitness levels, changing goals, personal preferences) of runners, providing only broad training guidance rather than more personalised support. The development of wearable sensors and mobile fitness applications facilitates the collection of a large amount of training data from runners. In this paper, we propose a recommender system that utilizes such training data to deliver more personalised training advice to runners, using ideas from case-based reasoning to reuse and adapt the training habits of similar runners. Explainability plays a significant role in this type of system, and we also describe how the predictions and recommendation advice can be presented to runners. An initial off-line evaluation is presented based on a large-scale, real-world dataset.Science Foundation IrelandInsight Research Centre2020-11-27 JG: Broken PDF replace

The Secondary Bile acids, Ursodeoxycholic acid and Lithocholic Acid, Protect Against Intestinal Inflammation by Inhibition of Epithelial Apoptosis

Increased epithelial permeability is a key feature of IBD pathogenesis and it has been proposed that agents which promote barrier function may be of therapeutic benefit. We have previously reported the secondary bile acid, ursodeoxycholic acid (UDCA), to be protective in a mouse model of colonic inflammation and that its bacterial metabolism is required for its beneficial effects. The current study aimed to compare the effects of UDCA, LCA, and a non-metabolizable analog of UDCA, 6-methyl-UDCA (6-MUDCA), on colonic barrier function and mucosal inflammation in a mouse model of colonic inflammation. Bile acids were administered daily to C57Bl6 mice by intraperitoneal injection. Colonic inflammation, induced by addition of DSS (2.5%) to the drinking water, was measured as disease activity index (DAI) and histological score. Epithelial permeability and apoptosis were assessed by measuring FITC-dextran uptake and caspase-3 cleavage, respectively. Cecal bile acids were measured by HPLC-MS/MS. UDCA and LCA, but not 6-MUDCA, were protective against DSS-induced increases in epithelial permeability and colonic inflammation. Furthermore, UDCA and LCA inhibited colonic epithelial caspase-3 cleavage both in DSS-treated mice and in an in vitro model of cytokine-induced epithelial injury. HPLC-MS/MS analysis revealed UDCA administration to increase colonic LCA levels, whereas LCA administration did not alter UDCA levels. UDCA, and its primary metabolite, LCA, protect against intestinal inflammation in vivo, at least in part, by inhibition of epithelial apoptosis and promotion of barrier function. These data suggest that clinical trials of UDCA in IBD patients are warranted

Patient-reported experience of clinical care of osteogenesis imperfecta (OI) during the COVID-19 pandemic

Background: Research on the effects of the COVID-19 pandemic on people with rare diseases is limited. Few studies compare healthcare throughout the progression of the ongoing pandemic. Aims: To assess the impact of the pandemic on individuals with osteogenesis imperfecta across two consecutive years, understand what challenges were encountered, and analyse the experience of remote consultation. Methods: An initial survey was distributed following the first lockdown in August 2020, and a second survey in April 2021. The surveys explored four themes- effects on therapy, alternatives to consultation, effect on mental health, and perceived risks of COVID-19. Results: In the 2020 survey, of the 110 respondents, 69 (63%) had at least one appointment delayed due to the lockdown, compared with 89 of the 124 respondents (72%) in 2021. Of the 110 respondents in 2020, 57 (52%) had a remote consultation, increasing to 92 of 124 (74%) in the follow-up survey. In the 2020 survey 63 of 91 respondents (69%) expressed anxiety due to lockdown, compared with 76 of 124 (61%) in 2021. The percentage of total respondents expressing a preference for remote consultation was 48% in 2020, increasing to 71% in 2021. Conclusions: The pandemic has had widespread effects on the mental and physical health of those with OI. These effects, alongside appointment delays, have increased as the pandemic progresses. Encouragingly, the increasing preference for remote consultation may indicate that this could be a viable long-lasting alternative to face-to-face appointments, especially for patients who previously traveled vast distances for specialist care

The MyD88+ phenotype is an adverse prognostic factor in epithelial ovarian cancer

The prognosis of epithelial ovarian cancer is poor in part due to the high frequency of chemoresistance. Recent evidence points to the Toll-like receptor-4 (TLR4), and particularly its adaptor protein MyD88, as one potential mediator of this resistance. This study aims to provide further evidence that MyD88 positive cancer cells are clinically significant, stem-like and reproducibly detectable for the purposes of prognostic stratification. Expression of TLR4 and MyD88 was assessed immunohistochemically in 198 paraffin-embedded ovarian tissues and in an embryonal carcinoma model of cancer stemness. In parallel, expression of TLR4 and MyD88 mRNA and regulatory microRNAs (miR-21 and miR-146a) was assessed, as well as in a series of chemosensitive and resistant cancer cells lines. Functional analysis of the pathway was assessed in chemoresistant SKOV-3 ovarian cancer cells. TLR4 and MyD88 expression can be reproducibly assessed via immunohistochemistry using a semi-quantitative scoring system. TLR4 expression was present in all ovarian epithelium (normal and neoplastic), whereas MyD88 was restricted to neoplastic cells, independent of tumour grade and associated with reduced progression-free and overall survival, in an immunohistological specific subset of serous carcinomas, p<0.05. MiR-21 and miR-146a expression was significantly increased in MyD88 negative cancers (p<0.05), indicating their participation in regulation. Significant alterations in MyD88 mRNA expression were observed between chemosensitive and chemoresistant cells and tissue. Knockdown of TLR4 in SKOV-3 ovarian cells recovered chemosensitivity. Knockdown of MyD88 alone did not. MyD88 expression was down-regulated in differentiated embryonal carcinoma (NTera2) cells, supporting the MyD88+ cancer stem cell hypothesis. Our findings demonstrate that expression of MyD88 is associated with significantly reduced patient survival and altered microRNA levels and suggest an intact/functioning TLR4/MyD88 pathway is required for acquisition of the chemoresistant phenotype. Ex vivo manipulation of ovarian cancer stem cell (CSC) differentiation can decrease MyD88 expression, providing a potentially valuable CSC model for ovarian cancer

The impact of immediate breast reconstruction on the time to delivery of adjuvant therapy: the iBRA-2 study

Background: Immediate breast reconstruction (IBR) is routinely offered to improve quality-of-life for women requiring mastectomy, but there are concerns that more complex surgery may delay adjuvant oncological treatments and compromise long-term outcomes. High-quality evidence is lacking. The iBRA-2 study aimed to investigate the impact of IBR on time to adjuvant therapy. Methods: Consecutive women undergoing mastectomy ± IBR for breast cancer July–December, 2016 were included. Patient demographics, operative, oncological and complication data were collected. Time from last definitive cancer surgery to first adjuvant treatment for patients undergoing mastectomy ± IBR were compared and risk factors associated with delays explored. Results: A total of 2540 patients were recruited from 76 centres; 1008 (39.7%) underwent IBR (implant-only [n = 675, 26.6%]; pedicled flaps [n = 105,4.1%] and free-flaps [n = 228, 8.9%]). Complications requiring re-admission or re-operation were significantly more common in patients undergoing IBR than those receiving mastectomy. Adjuvant chemotherapy or radiotherapy was required by 1235 (48.6%) patients. No clinically significant differences were seen in time to adjuvant therapy between patient groups but major complications irrespective of surgery received were significantly associated with treatment delays. Conclusions: IBR does not result in clinically significant delays to adjuvant therapy, but post-operative complications are associated with treatment delays. Strategies to minimise complications, including careful patient selection, are required to improve outcomes for patients

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK ‘Alert Level 4’ phase of the B-MaP-C study

Abstract: Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown
