Miltefosine (MIL)–allopurinol combination therapy administered at standard dosage is effective to treat canine leishmaniosis, nevertheless for some dogs the digestive tolerance of MIL is not acceptable. This study evaluates an alternative therapeutic protocol by using a modified dosage of MIL to increase its effectiveness and improve the digestive tolerance. Thirty-four Leishmania infantum owned naturally infected dogs were included and monitored for 180 days. The dogs were allocated in two randomized groups: Group X−18 dogs treated with MIL registered dose of 2 mg/kg, oral administration, once daily, for 28 days; Group Y−16 dogs treated with 1.2 mg/kg for 5 days followed by 2.5 mg/kg for 25 days. Both groups were also treated with allopurinol. Digestive tolerance was monitored by adverse events observation. Treatments effectiveness was evaluated by monitoring the reduction of clinical score, the improvement of clinicopathological abnormalities, the reduction of parasitological load by PCR and the number of relapses. 16.6% dogs of group X and 12.5% dogs of group Y showed treatment associated adverse events. The reduction of clinical score was 61.7% for group X and 71.6% for group Y. All dogs showed an improvement of laboratory parameters after treatment. Quantitative PCR showed better results in group Y compared to group X; relapses were only registered in four dogs of group X. The modified protocol demonstrates a better trend of results in term of tolerance, clinical effectiveness, parasitological load reduction and relapses control, suggesting it could be considered for new large-scale studies.

Small-angle x-ray scattering and quasi-elastic light scattering measurements were conducted to analyze correlations between the structure and short-time dynamics of tyrocidine B·hydrochloride (TrcB) in ethanol, acetonitrile, and (R,S)-2-methylbutanol dispersions in the presence of 20.0% (v/v) water at 278 K and 298 K. The three TrcB dispersions exhibited peak position shifts that varied with the volume fraction. The experimental data were fitted to a model that considered the effective interaction potential, short-range attraction, and long-range repulsion. This model of repulsively interacting single TrcB particles is incompatible with the presence of equilibrium aggregate phases. The self-diffusion coefficient at the short-time limit (Dsh) decreased more as the TrcB concentration increased than one would expect for a corresponding hard-sphere or charged particle at the same volume fraction. At low volume fractions, the system consisted of monomers, dimers, and trimers. At high TrcB volume fractions, the main particles were larger aggregates. The collective diffusion coefficient, Dc, was constant when Q > Qc, where Qc is the position of the interference peak, which implies that there were no inter-monomer TrcB oligomer dynamics. This is because Dsh/D0 decayed much more quickly than the TrcB monomer as a function of the volume fraction. In vitro experiments revealed that antimicrobial activities were preserved at all volume fractions notwithstanding the presence of various oligomers.

AimThe present study aims to develop the Race-related Attitudes and Multiculturalism Scale (RRAMS), as well as to perform an initial psychometric assessment of this instrument in a national sample of Australian adults.MethodsThe sample comprised 2,714 Australian adults who took part in the 2013 National Dental Telephone Interview Survey (NDTIS), which includes a telephone-based interview and a follow-up postal questionnaire. We used Exploratory Factor Analysis (EFA) to evaluate the RRAMS' factorial structure (n = 271) and then proceeded with Confirmatory Factor Analysis (CFA) to confirm the proposed structure in an independent sample (n = 2,443). Measurement invariance was evaluated according to sex, age and educational attainment. Construct validity was assessed through known-groups comparisons. Internal consistency was assessed with McDonald's ΩH and ordinal α. Multiple imputation by chained equations was adopted to handle missing data.ResultsEFA indicated that, after excluding 4 out of the 12 items, a two-factor structure provided a good fit to the data. This configural structure was then confirmed in an independent sample by means of CFA (χ2(19) = 341.070, pConclusionsThe RRAMS appears to be a valid and reliable measure to evaluate multiculturalist attitudes in the Australian context. The instrument may be useful in the assessment and monitoring of interventions aiming to promote multiculturalist inclusive attitudes and to increase social cohesion in Australia.

The effect of Leishmania infantum soluble antigen (LSA) and recombinant Kinetoplastid Membrane Protein 11 (rKMP11) on the induction of ex vivo specific IFN-γ (n = 69) and antibody responses (n = 108) was determined in dogs. All dogs were tested for serological response to both antigens and divided into Group 1: healthy (Asturias, Spain, n = 26), Group 2: sick (n = 46), Group 3: healthy Ibizan hounds (Mallorca, Spain, n = 22) and Group 4: healthy (Bari, Italy, n = 14). Antibody levels were higher for LSA when compared to rKMP11 (p = 0.001). Ibizan hounds were all seronegative to rKMP11 and 18% were low seropositive to LSA. Sick dogs presented higher antibody response to both antigens compared to the rest of the groups (p < 0.0001). All groups showed higher IFN-γ levels after LSA compared to rKMP11 responses (p < 0.05). The highest response to LSA was found in Ibizan hounds (p < 0.05). IFN-γ to LSA and rKMP11 stimulation was observed in 34% and in 2.8% of the sick dogs, respectively. Here, we demonstrated that anti-rKMP11 antibodies are mainly present in dogs with moderate to severe disease. Furthermore, cellular immune response measured by specific ex vivo IFN-γ production was more intense to LSA than stimulated to rKMP11.

Abstract Introduction The incidence of left ventricular (LV) thrombus formation in ST-segment elevation myocardial infarction (STEMI) patients in the current era of primary percutaneous coronary intervention (PCI) is not well established. We performed a meta-analysis to assess the actual incidence and predictors of LV thrombus by cardiovascular magnetic resonance (CMR) in STEMI treated by primary PCI. Methods We searched MEDLINE and EMBASE databases up to February 2018. We included all studies published as a full-text article, reporting the incidence of LV thrombus by CMR within 1 month following acute STEMI in patients treated by primary PCI. A binary random-effects model was used to estimate the pooled incidence of LV thrombus. The diagnostic performance of transthoracic echocardiography (TTE) as compared with CMR was pooled to obtain the sensitivity and specificity of TTE with CMR as the gold standard. Embolic and bleeding complications of LV thrombus were also evaluated. Results Ten studies were included in the meta-analysis. The incidence of LV thrombus by CMR in all-comer STEMI patients (n = 2072) was 6.3% with 96% of LV thrombus occurring in those with anterior STEMI (12.2% incidence). When only anterior STEMI with LVEF

Abstract Background High rates of suicidal behaviours among Indigenous Australians have been documented. Justice-involved individuals are also at a higher risk for engaging in suicidal behaviours. This study sought to ascertain the prevalence and correlates of suicidal behaviours for 107 Indigenous adult males in custody in Victoria, Australia. Methods Participants undertook a structured interview comprising a psychiatric assessment. Information on suicidal behaviours (ideation and attempts), socio-demographics, environmental stressors, negative life events and mental health was obtained. Results A high proportion of Indigenous males in custody experienced lifetime suicidal ideation (63.7%) and over one-half had attempted suicide (54.5%). A smaller, yet significant number of participants experienced ideation over the past 12 months (27.9%). Having a loved one pass away within the past 12 months predicted recent ideation; lifetime ideation and a diagnosis of Post-Traumatic Stress Disorder predicted a lifetime suicide attempt. Conclusions The prevalence of suicidal behaviours among Indigenous people in custody is remarkably high. Correlates of suicidal behaviours for Indigenous people in custody in this study likely manifest in the community, denoting an urgent public health response. Prevention must begin in communities at-risk for suicidal behaviours. The development of low intensity mental health service infrastructure in communities to promote awareness and provide accessible, least restrictive support and treatment is necessary. Correctional institutions must also continue to improve custodial suicide prevention and management initiatives.

Abstract Background Suicidal ideation is common in patients suffering from panic disorder. The present study investigated rates of suicidal ideation and risk factors for suicidal ideation in a sample of primary care patients suffering from panic disorder with or without agoraphobia. Methods A total of N = 296 patients [n = 215 (72.6%) women; age: M = 43.99, SD = 13.44] were investigated. Anxiety severity, anxiety symptoms, avoidance behavior, comorbid depression diagnosis, severity of depression, age, sex, employment status, living situation and frequency of visits at the general practitioner were considered as risk factors of suicidal ideation. Results Suicidal ideation was experienced by 25% of the respondents. In a logistic regression analysis, depression diagnosis and depression severity emerged as significant risk factors for suicidal ideation. Anxiety measures were not associated with suicidal ideation. Conclusion Suicidal ideation is common in primary care patients suffering from panic disorder with or without agoraphobia. Individuals with greater burden of mental illness in terms of mood disorder comorbidity and depressive symptomatology are especially likely to suffer from suicidal ideation.

Abstract Background Type 2 diabetes mellitus (T2DM) remains a public health problem in low-income countries, including African countries. Risk factors of this disease in Africa are still unclear. This study will examine the modifiable and emerging risk factors associated with T2DM in Africa. Methodology The study will include a systematic review and meta-analysis of published and unpublished empirical studies, reporting quantitative data only. We will conduct a search on scientific databases (e.g. Global Health), general online search engines (e.g. Google Scholar) and key websites for grey literature using a combination of key countries/geographic terms, risk factors (e.g. overweight/obesity) and T2DM (including a manual search of the included reference lists). We will use the Comprehensive Meta-Analysis Software (CMA) version 2.0 for data management and analysis. This protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Discussion The systematic review and meta-analysis will provide a robust and reliable evidence base for policy makers and future research. This may help with identifying and implementing more cost-effective diabetes prevention strategies and improved resource allocation. Systematic review registration This protocol has been registered with the PROSPERO international prospective register of systematic reviews. The reference number is CRD42016043027.

Abstract Background Disparities across a number of health indicators between the general population and particular racial and cultural minority groups including African Americans, Native Americans and Latino/a Americans have been well documented. Some evidence suggests that particular groups may receive poorer standards of care due to biased beliefs or attitudes held by health professionals. Less research has been conducted in specifically non-urban areas with smaller minority populations. Methods This study explored the self-reported health care experiences for 117 racial and cultural minority Americans residing in a Mid-Western jurisdiction. Prior health care experiences (including perceived discrimination), attitudes towards cultural competence and satisfaction with health care interactions were ascertained and compared across for four sub-groups (African-American, Native American, Latino/a American, Asian American). A series of multiple regression models then explored relationships between a concert of independent variables (cultural strength, prior experiences of discrimination, education level) and health care service preferences and outcomes. Results Overall, racial/cultural minority groups (African Americans, Native Americans, Latino/a Americans, and Asian Americans) reported general satisfaction with current healthcare providers, low levels of both health care provider racism and poor treatment, high levels of cultural strength and good access to health care services. Native American participants however, reported more frequent episodes of poor treatment compared to other groups. Incidentally, poor treatment predicted lower levels of treatment satisfaction and racist experiences predicted being afraid of attending conventional health care services. Cultural strength predicted a preference for consulting a health care professional from the same cultural background. Conclusions This study provided a rare insight into minority health care expectations and experiences in a region with comparatively lower proportions of racial and cultural minorities. Additionally, the study explored the impact of cultural strength on health care interactions and outcomes. While the bulk of the sample reported satisfaction with treatment, the notable minority of participants reporting poor treatment is still of some concern. Cultural strength did not appear to impact health care behaviours although it predicted a desire for cultural matching. Implications for culturally competent health care provision are discussed within.

Type 2 diabetes mellitus (T2DM) is a significant public health concern in Africa. While the associations between modifiable risk factors and T2DM are likely to be Africa-specific, their overall estimations have not been published. This study aimed to use systematic and meta-analytic methods to examine the strength of associations between modifiable risk factors and T2DM in Africa. A systematic search of literature published between January 2000 to March 2022 was conducted. The review included only population-based studies and data extracted from 57 studies. Of these, unadjusted data from 50 studies were included in meta-analysis. With considerable heterogeneity between studies, random-effect models were calculated to ascertain the odds ratios (OR) and 95% confidence intervals (CI) for the associations between obesity (OB) and overweight (OV), defined by BMI; central obesity (waist circumference (OB-WC), waist-to-hip-ratio (OB-WHR)), alcohol, fruit and vegetable consumption, smoking, physical activity (PA) and T2DM. Moderator effects of age, African regions, and urban/rural location were assessed. Risk factors associated with T2DM include BMI-OB [OR = 3.05, 95% CI: (2.58, 3.61)], BMI-OV [OR = 2.38, 95% CI: (1.51, 3.75)], and BMI-OV/OB [OR = 2.07, 95% CI: (1.82, 2.34)]; OB-WC [OR = 2.58, 95% CI: (2.09, 3.18)] and OB-WHR [OR = 2.22, 95% CI: (1.69, 2.92)]; PA [OR = 1.85, 95% CI: (1.50, 2.30)]. Significant moderator effects were not observed. Obesity defined by BMI and central obesity, but not behavioral risk factors were most strongly associated with T2DM in African populations, emphasizing the need for obesity prevention to limit the rise of T2DM. The PROSPERO registration number is CRD42016043027. • BMI-OB and WC-OB were most strongly associated with T2DM. • WHR-OB was less strongly associated with T2DM. • BMI-OB or WC-OB may be used as screening tools for T2DM risk among Africans.

Objectives: The American Heartworm Society medical protocol represents the current standard of therapy for canine heartworm disease without caval syndrome. However, data on the tolerability of this protocol are limited. This study aimed to describe efficacy and prevalence of possible treatment‐related side effects in dogs with heartworm disease treated using the American Heartworm Society protocol. Materials and Methods: For this retrospective multi‐centre cohort study, dogs diagnosed with classes 1 to 3 heartworm disease that completed the American Heartworm Society medical protocol were searched in four medical databases. Demographic, clinical, diagnostic, therapeutic and outcome data, including the number and type of possible treatment‐related side effects, were retrieved. Results: Thirty‐five dogs were included. The median age and bodyweight were 6 years (1 to 13 years) and 17.3 kg (4.9 to 50 kg), respectively. Heartworm disease was classified as classes 1, 2 and 3 in 20 of 35, 11 of 35 and four of 35 dogs, respectively. In addition to the therapeutic recommendations of the American Heartworm Society, eight of 35 dogs underwent sedation to favour melarsomine administration, and 30 of 35 received ice at the injection site. After adulticide therapy, all dogs were hospitalised with cage rest [median time 12 hours (6 to 48 hours)]. All dogs survived the treatment. All dogs with long‐term follow‐up (32/35) became negative. Furthermore, treatment‐related side effects were rare, mild and rapidly recovered without the need for supporting therapies; these included depression/lethargy (4/35 dogs), cough (2/35 dogs) and lameness, pain and gastrointestinal signs (1/35 dog each). Clinical Significance: The American Heartworm Society medical protocol is efficient and safe in dogs with classes 1 to 3 heartworm disease. [ABSTRACT FROM AUTHOR]

In a highly globalised world with increasing ethno-nationalistic tensions and conflicts, the importance of intercultural education has never been greater. The challenge remains, however, as to whether educating for mutual respect and social cohesion can be achieved through traditional modes of schooling or whether additional approaches that are not necessarily school-centric are required. Drawing on in-depth qualitative data including video diaries, narrative interviews and focus groups with Australian secondary school students and semi-structured interviews with teachers, this paper discusses such an endeavour in which a museum exhibition on identity and belonging is employed as an interactive space for meaningful encounter among students and as a form of professional learning that enlivened teaching practice. Using the concept of reflexive ethnicity, this paper examines whether cognitive and affective encounters outside the "school gate" create opportunities for critical learning about ethnicity that can complement and enhance school curricula and classroom learning. More importantly, the paper explores how the possibility of building on such activities to create and sustain teaching practice can challenge entrenched static notions of ethnicity. The paper concludes that reflexive encounters with "difference" within an interactive museum space can unsettle prejudice and provide a deeper and more meaningful understanding of ethnic identity that goes beyond rote classroom learning.

Ethnic-racial socialisation is broadly described as processes by which both minority and majority children and young people learn about and negotiate racial, ethnic and cultural diversity. This article extends the existing ethnic-racial socialisation literature in three significant ways: (1) it explores ways children make sense of their experiences of racial and ethnic diversity and racism; (2) it considers ways children identify racism and make distinctions between racism and racialisation; and (3) it examines teacher and parent ethnic-racial socialisation messages about race, ethnicity and racism with children. This research is based on classroom observations, semi-structured interviews and focus groups with teachers, parents and students aged 8-12 years attending four Australian metropolitan primary schools. The findings reveal that both teachers and parents tended to discuss racism reactively rather than proactively. The extent to which racism was discussed in classroom settings depended on: teachers' personal and professional capability; awareness of racism and its perceived relevance based on student and community experiences; and whether they felt supported in the broader school and community context. For parents, key drivers for talking about racism were their children's experiences and racial issues reported in the media. For both parents and teachers, a key issue in these discussions was determining whether something constituted either racism or racialisation. Strategies on how ethnic-racial socialisation within the school system can be improved are discussed.

Abstract Background Possessing a strong cultural identity has been shown to protect against mental health symptoms and buffer distress prompted by discrimination. However, no research to date has explored the protective influences of cultural identity and cultural engagement on violent offending. This paper investigates the relationships between cultural identity/engagement and violent recidivism for a cohort of Australian Indigenous people in custody. Methods A total of 122 adults from 11 prisons in the state of Victoria completed a semi-structured interview comprising cultural identification and cultural engagement material in custody. All official police charges for violent offences were obtained for participants who were released from custody into the community over a period of 2 years. Results No meaningful relationship between cultural identity and violent recidivism was identified. However a significant association between cultural engagement and violent recidivism was obtained. Further analyses demonstrated that this relationship was significant only for participants with a strong Indigenous cultural identity. Participants with higher levels of cultural engagement took longer to violently re-offend although this association did not reach significance. Conclusions For Australian Indigenous people in custody, ‘cultural engagement’ was significantly associated with non-recidivism. The observed protective impact of cultural engagement is a novel finding in a correctional context. Whereas identity alone did not buffer recidivism directly, it may have had an indirect influence given its relationship with cultural engagement. The findings of the study emphasize the importance of culture for Indigenous people in custody and a greater need for correctional institutions to accommodate Indigenous cultural considerations.

Abstract Background The Localities Embracing and Accepting Diversity (LEAD) programme was established to improve the health of ethnic minority communities through the reduction of racial discrimination. Local governments in the state of Victoria, Australia, were at the forefront of LEAD implementation in collaboration with leading state and national organisations. Key aims included expanding the available evidence regarding effective anti-racism interventions and facilitating the uptake of this evidence in organisational policies and practices. Methods One rural and one metropolitan local government areas were selected to participate in LEAD. Key informant interviews and discussions were conducted with individuals who had participated in LEAD implementation and members of LEAD governance structures. Data were also collected on programme processes and implementation, partnership formation and organisational assessments. Results The LEAD model demonstrated both strengths and weaknesses in terms of facilitating the use of evidence in a complex, community-based health promotion initiative. Representation of implementing, funding and advisory bodies at different levels of governance enabled the input of technical advice and guidance alongside design and implementation. The representation structure assisted in ensuring the development of a programme that was acceptable to all partners and informed by the best available evidence. Simultaneous evaluation also enhanced perceived validity of the intervention, allowed for strategy correction when necessary and supported the process of double-loop organisational learning. However, due to the model’s demand for simultaneous and intensive effort by various organisations, when particular elements of the intervention were not functional, there was a considerable loss of time and resources across the partner organisations. The complexity of the model also presented a challenge in ensuring clarity regarding roles, functions and the direction of the programme. Conclusions The example of LEAD provides guidance on mechanisms to strengthen the entry of evidence into complex community-based health promotion programmes. The paper highlights some of the strengths and weaknesses of the LEAD model and implications for practical collaboration between policymakers, implementers and researchers.

Abstract Background The increasing number of reports of human infections by Strongyloides stercoralis from a range of European countries over the last 20 years has spurred the interest of the scientific community towards this parasite and, in particular, towards the role that infections of canine hosts may play in the epidemiology of human disease. Data on the epidemiology of canine strongyloidiasis is currently limited, most likely because of the inherent limitations of current diagnostic methods. Methods Faecal samples were collected directly from the rectal ampulla of 272 animals of varying age and both genders living in Apulia, southern Italy. Dogs included were either privately owned (n = 210), living in an urban area but with unrestricted outdoor access (Group 1), or shelter dogs (n = 62 out of ~400) hosted in a single shelter in the province of Bari in which a history of diarrhoea, weight loss, reduced appetite and respiratory symptoms had been reported (Group 2). Strongyloides stercoralis infection was diagnosed by coproscopy on direct faecal smear and via the Baermann method. Results Six of 272 dogs were positive for S. stercoralis at the Baermann examination; all but one were from the shelter (Group 2) and displayed gastrointestinal clinical signs. The only owned dog (Group 1) infected with S. stercoralis, but clinically healthy, had been adopted from a shelter 1 year prior to sampling. Five infected dogs were treated with fenbendazole (Panacur®, Intervet, Animal Health, 50 mg/kg, PO daily for 5 days), or with a combination of fenbendazole and moxidectin plus imidacloprid spot-on (Im/Mox; Advocate® spot-on, Bayer). Post-treatment clearance of infection was confirmed in three dogs by Baermann examination, whereas treatment failure was documented in two dogs by Baermann and/or post-mortem detection of adult parasites. Conclusions This study describes, for the first time, the presence of S. stercoralis infection in sheltered dogs from southern Italy. Data indicate that S. stercoralis infection may pose a concern for sheltered animals and raise questions on potential risks of infection for staff of municipal shelters in southern European countries. Given that a single course of treatment with fenbendazole, associated or not with Im/Mox spot-on, may not eliminate the infection, effective treatment protocols should be investigated and control strategies targeting the environment considered for reducing the risk of zoonotic infection.

IntroductionPositive attitudes towards ethnic-racial identity (ERI) is a key factor in Aboriginal Australian children's development. The present study aims to offer evidence of construct and criterion validity, reliability, and measurement invariance of a brief measure of Aboriginal children's ERI affirmation.MethodsData was from 424 children aged 10-12 years (mean 10.5 years; SD 0.56) participating in the 8th wave of the Longitudinal Study of Indigenous Children (LSIC). Information on ERI was obtained from 4 child-reported items. Sociodemographic characteristics and child social and emotional outcomes were caregiver-reported. A factorial structure was tested by Confirmatory Factor Analysis. The estimation method was weighted least squares with mean and variance adjusted test statistic (WLSMV). For reliability verification, the ordinal α and Ω hierarchical α were assessed. For construct validity, a generalized linear model with log-Poisson link estimated the association between ERI and children's social and emotional outcomes. We hypothesized that children with positive ERI would have lower behavioural and emotional difficulties.ResultsWe found evidence of excellent fit for a unidimensional model of ERI affirmation after adjusting for correlated uniqueness between items 1 and 3 (χ2(2) = 0.06, p = 0.80; RMSEA = 0.000 [90% CI 0.000-0.080], p = 0.088; CFI = 1.000). Internal consistency reliability was considered adequate (ordinal α = 0.83; Ω hierarchical α = 0.72). The unidimensional model was shown to be invariant among boys and girls (Δχ2 (4) = 6.20, p = 0.18; ΔCFI = 0.000). Higher ERI was associated with lower risk of problematic scores (>17) on the SDQ (Risk Ratioa = 0.91, 95% CI 0.64, 1.29).DiscussionThe four LSIC items perform as a brief measure of Aboriginal children ERI affirmation among boys and girls. Results contribute much needed evidence for LSIC's ongoing success and to future research on Aboriginal children's development and wellbeing.

ObjectivesThis study investigates the protective role of ethnic-racial identity (ERI) affirmation on the longitudinal association between racism and Aboriginal Australian children's social and emotional well-being (SEWB).Methods408 children from the K-Cohort of the Longitudinal Study of Indigenous Children were included in the analysis. Data were collected through questionnaire-guided interviews at 7-10 and 9-12 years of age. Children's racism experience, SEWB (Strengths and Difficulties Questionnaire), and confounding were reported by caregivers. ERI was reported by children and dichotomized into high versus low. Generalized linear models with log-Poisson links and robust errors were used to estimate adjusted Risk Ratios (RRa) for the effect of racism on SEWB domains. Effect-measure modification analysis was used to verify differences on effect sizes per strata of ERI affirmation. The presence of modification was indicated by the Relative Excess Risk due to Interaction (RERI).ResultsSlightly above half (51.4%) of the children presented high ERI affirmation. Children exposed to racism and with low ERI affirmation were at increased risk of hyperactive behavior (RRa 2.53, 95% CI 1.17, 5.48), conduct problems (RRa 2.35, 95% CI 1.07, 5.15), and total difficulties (RRa 1.73, 95% CI 0.84, 3.55). Positive RERIs indicated the joint effects of racism and low ERI affirmation surpassed the sum of their separate effects in these domains. Children with high ERI affirmation were at increased risk of peer problems (RRa 1.66, 95% CI 0.78, 3.52).ConclusionsThese findings suggest that ERI may mitigate the risk of poor SEWB due to racism. Fostering affirmative ERI can be an important strategy in promoting resilience in Aboriginal Australian children.

In parallel with many nations' education policies, national education policies in Australia seek to foster students' intercultural understanding. Due to Australia's location in the Asia-Pacific region, the Australian government has focused on students becoming "Asia literate" to support Australia's economic and cultural engagement with Asian countries. Drawing on Allport's optimal contact principles and key factors supporting intercultural understanding, this study examines two "sister school" cultural immersion trips in Indonesia and East Timor to explore ways in which their different approaches supported positive intergroup contact and helped foster intercultural understanding among students. Focus groups and interviews with school project teams and analysis of both researcher and teacher project field notes and documents suggested that these schools' programmes could be mapped onto Allport's contact principles in different ways. The paper concludes with promising approaches that can help to inform sister school programmes.

The optimal treatment strategy for coronary bifurcation lesions by percutaneous coronary intervention (PCI) is complex and remains a subject of debate. Current guidelines advise a stepwise provisional approach with optional two-stent strategy. However, a two-stent strategy, both upfront and stepwise provisional, is technically demanding. Therefore, there is increasing interest in the use of drug-eluting balloons (DEB) in bifurcation lesions, mainly after a provisional approach with unsatisfactory result of the side branch. Some small pilot studies already showed that the use of DEB in bifurcation lesions is safe and feasible. However, a randomized comparison of this hybrid DEB strategy with a two-stent strategy is currently lacking. The Hybrid DEB study is a prospective, multicenter, randomized controlled trial investigating noninferiority of a hybrid DEB approach, using a combination of a drug-eluting stent (DES) in the main vessel and DEB in the side branch, compared to stepwise provisional two-stent strategy in patients with true bifurcation lesions. A total of 500 patients with de novo true coronary bifurcation lesions, treated with a stepwise provisional approach and an unsatisfactory result of the side branch after main vessel stenting (≥ 70% stenosis and/or < thrombolysis in myocardial infarction III flow), will be randomized in a 1:1 ratio to receive either treatment with a DEB or with a DES in the side branch. The primary endpoint is a composite endpoint of the occurrence of all-cause death, periprocedural or spontaneous myocardial infarction and/or target vessel revascularization at the anticipated median 2-year follow-up. The Hybrid DEB study will compare in a multicenter, randomized fashion a hybrid DEB approach with a stepwise provisional two-stent strategy in patients with true bifurcation lesions.

Abstract Background Racial discrimination is a pervasive social problem in several advanced countries such as the U.S., U.K., and Australia. Public health research also indicates a range of associations between exposure to racial discrimination and negative health, particularly, mental health including depression, anxiety, and post-traumatic stress disorder (PTSD). However, the direct negative health impact of racial discrimination has not been costed so far although economists have previously estimated indirect non-health related productivity costs. In this study, we estimate the burden of disease due to exposure to racial discrimination and measure the cost of this exposure. Methods Using prevalence surveys and data on the association of racial discrimination with health outcomes from a global meta-analysis, we apply a cost of illness method to measure the impact of racial discrimination. This estimate indicates the direct health cost attributable to racial discrimination and we convert the estimates to monetary values based on conventional parameters. Results Racial discrimination costs the Australian economy 235,452 in disability adjusted life years lost, equivalent to $37.9 billion per annum, roughly 3.02% of annual gross domestic product (GDP) over 2001–11, indicating a sizeable loss for the economy. Conclusion Substantial cost is incurred due to increased prevalence of racial discrimination as a result of its association with negative health outcomes (e.g. depression, anxiety and PTSD). This implies that potentially significant cost savings can be made through measures that target racial discrimination. Our research contributes to the debate on the social impact of racial discrimination, with implications for policies and efforts addressing it.

The cadherin family of calcium-dependent cell adhesion molecules plays an important part in the organization of cell adhesion and tissue segregation during development. The expression pattern and the binding specificity of each cadherin are of principal importance for its role in morphogenesis. B-Cadherin and LCAM, two chicken cadherins, have similar, but not identical, spatial and temporal patterns of expression. To examine the possibility that they might bind to one another in a heterophilic manner, we generated, by cDNA transfection, L-cell lines that express LCAM or B-cadherin. We then examined the abilities of these cells to coaggregate with each other and with other cadherin-expressing cells in short-term aggregation assays. The B-cadherin- and the LCAM-expressing cell lines segregate from P-, N-, or R-cadherin-expressing cells. B-cadherin- and LCAM-expressing cell lines, however, appear to be completely miscible, forming large mixed aggregates. Chick B-cadherin and murine E-cadherin also form mixed aggregates, indistinguishable from homophilic aggregates. Murine E-cadherin and chick LCAM coaggregate less completely, suggesting that the heterophilic interactions of these two cell lines are weak relative to homophilic interactions. These data suggest that heterophilic interactions between B-cadherin and LCAM are important during avian morphogenesis and help identify the amino acids in the binding domain that determine cadherin specificity.

Laparoscopic adrenalectomy has become a common alternative to open surgery for the resection of adrenal lesions in adults: The advantages are to provide better exposure of the adrenal gland, diminish soft tissue dissection, decrease morbidity and postoperative pain; however, reporting on the laparoscopic adrenalectomy in paediatric patients has been limited. We present two cases of laparoscopic adrenalectomy performed at our institution in two children, for left adrenal neuroblastoma in a first patient with opsomyoclonus syndrome, and for a right incidentaloma in the second case. According to recent literature, our experience has demonstrated that the laparoscopic adrenalectomy is a feasible procedure in children with small, well-circumscribed adrenal masses: It can be used a safety to treat suspected benign and malignant adrenal masses in children, with minimal morbidity and short hospital stay. The lateral trans-peritoneal approach offers optimal visualisation and good outcomes in terms of minimal discomfort, rapid recovery and excellent cosmesis. However, in the paediatric field, the number of patients is limited, making the learning curve longer.

In eukaryotic cells, mitochondria are involved in a large array of metabolic and bioenergetic processes that are vital for cell survival. Phospholipids are the main building blocks of mitochondrial membranes. Cardiolipin (CL) is a unique phospholipid which is localized and synthesized in the inner mitochondrial membrane (IMM). It is now widely accepted that CL plays a central role in many reactions and processes involved in mitochondrial function and dynamics. Cardiolipin interacts with and is required for optimal activity of several IMM proteins, including the enzyme complexes of the electron transport chain (ETC) and ATP production and for their organization into supercomplexes. Moreover, CL plays an important role in mitochondrial membrane morphology, stability and dynamics, in mitochondrial biogenesis and protein import, in mitophagy, and in different mitochondrial steps of the apoptotic process. It is conceivable that abnormalities in CL content, composition and level of oxidation may negatively impact mitochondrial function and dynamics, with important implications in a variety of pathophysiological situations and diseases. In this review, we focus on the role played by CL in mitochondrial function and dynamics in health and diseases and on the potential of pharmacological modulation of CL through several agents in attenuating mitochondrial dysfunction.

Autochthonous human and canine strongyloidiasis is reported in Europe but is unclear whether the transmission of infection still occurs. We report a previously unpublished human case in an Italian teen and perform a systematic review of literature on autochthonous human and canine strongyloidiasis in Europe to investigate the current dynamic of transmission. Overall, 109 papers published after 1987 were included and one previously unpublished Italian case was added. Eighty case reports were retrieved and 42 of them (52.5%) had severe strongyloidiasis. Most cases were diagnosed in Spain, Italy and France. The median age was 58, the most represented age group was 61–70 years, 11 patients were under 30, and 7 of them were diagnosed after 2000. Epidemiological studies on human strongyloidiasis showed prevalence ranging from 0.56% to 28%. Overall, agriculture work, mine work and walking barefoot were the most commonly reported risk factors for infection. Canine strongyloidiasis was reported mainly in Italy (68 cases), but a few cases occurred also in Iceland, Finland, England, Germany, France, Switzerland, Russia, Slovakia, Romania and Greece. Autochthonous strongyloidiasis is still reported in Europe and sporadic transmission still occurs. Health care professionals should be aware of this issue to identify infected subjects and avoid adverse outcomes, especially in immunosuppressed patients. Further investigations are needed to clarify the zoonotic transmission of this nematode.

This paper begins with a brief overview of the origins and continued use of standpoint theory in the social sciences. It highlights both historical and contemporary challenges to the utility of standpoint theory as a critical scholarly tool, including developments such as intersectionality and transgenderism / transracialism. Specifically, the implications of a post-truth era for standpoint theory are considered alongside the affective turn, purity politics and the critique of critique. Given the slow, but steady, erosion of the ivory tower in which academics enjoyed privileged access to ‘truth’, this paper concludes with the need to foster scholar activism via new forms of knowledge politics that move beyond existing approaches to standpoint theory.

Early and successful myocardial reperfusion with primary percutaneous coronary intervention (pPCI) is the optimal therapy for patients presenting with ST segment elevation myocardial infarction (STEMI). Despite successful epicardial reopening of the infarct related artery, myocardial perfusion may not be restored in up to 40-50% of patients. This phenomenon, referred to as no-reflow (NR), recognizes several pathogenetic components including distal atherothrombotic embolization, ischaemic injury, reperfusion damage, intramyocardial hemorrhage and individual susceptibility of coronary microcirculation. However the complexity of pathogenesis remains still unclear. Moreover, cause NR plays a crucial role in patients prognosis, accurate detection is critical and multiple novel diagnostic modalities has been recently assessed.The NR phenomenon represents a challenge in the management of STEMI patients and has recently captured a growing interest of both basic scientists and interventional cardiologists. Although relevant efforts to transfer into real world practice new therapeutic strategies, to date there is still weak evidence of clinical improvement in this setting. Several strategies of prevention and treatment of NR have been proposed in the clinical arena including pharmacological and mechanical interventions. Nevertheless, the complexity of the phenomenon makes extremely unlikely for a single therapy to be effective. Understanding the interaction between the components of this pathway, along with exploring newer and more effective agents may enable patients to be treated with the most appropriate therapy.

Despite its acknowledged benefits for health promotion, the full potential of persuasive technology is not (yet) reached in regard to usability, effectiveness, and reproducibility. It often lacks an effective combination of technical features and behavior change strategies. This paper presents a multidisciplinary approach, addressing both aspects. It builds on the frameworks of situated Cognitive Engineering and Intervention Mapping. The approach generates building blocks from theory originating from different relevant disciplines; it specifies change objectives and requirements, described in the context of use, for intervention (strategy) and interaction (technology); it evaluates process, effect and impact, whereby claims on interaction and intervention are validated. To cope with language barriers between developers from different disciplines, the approach is presented as a guideline, illustrated with a case study. This approach is expected to contribute to a sound design rationale, a broad reach and ongoing use of the technology, and larger results in regard to health promotion.

Background: In chronic heart failure (CHF) patients there is a wide variability in the minimal effective diuretic dose. The aim of this study is to evaluate whether renal resistance index (RRI) is associated to baseline diuretic dose and the changes at one year. Methods and results: 250 outpatients in a stable condition and in conventional therapy were enrolled. Baseline RRI was calculated by renal arterial Doppler. The total daily dose of loop diuretics was assessed at baseline and after one year. High diuretic dose (HDD) was defined as a daily furosemide equivalent dose >100 mg. RRI was independently associated with baseline HDD at univariate (OR 1.39; 95% CI: 1.233–1.58; p

Mitral regurgitation (MR) is the most frequent valvulopathy in the general population with an incidence that grows with age and is associated with a poor prognosis. Regardless of its primary cause, which can be both ischaemic and non-ischaemic cardiomyopathy, it finally activates a self-feeding process. Due to the complexity of mitral valve (MV) apparatus and its interaction with the myocardium, even the diagnosis could represent a challenge for physicians. Higher technological instruments such as 3D echocardiography and cardiac magnetic resonance could play an important role in the evaluation of MV. In this paper we reviewed the most salient aspects of functional MR pathophysiology as well as the current diagnostic methods. The management of functional mitral regurgitation (FMR) is even more challenging and controversial; the optimal approach, timing, and effectiveness of interventions are still debated. Treatment of FMR begins with optimal medical therapy for left ventricular dysfunction, including cardiac resynchronisation when indicated. While functional improvement after surgery is well established, the benefits in terms of survival are still questionable. Moreover, in patients with high perioperative risk there is a growing interest in emerging percutaneous techniques. Among a variety of medical, surgical, and percutaneous opportunities, authors support an accurate case-by-case evaluation to find a tailored and stepwise treatment according to anatomical features and patient comorbidities.
