Understanding and responding to racism and the provision of culturally safe care by interdisciplinary health professionals in the aged care sector in regional, rural and remote areas: a scoping review

INTRODUCTION

This scoping review was undertaken to obtain conceptual clarification about how racism and cultural safety are understood by interdisciplinary health professionals globally in the aged care sector in regional, rural and remote areas. There is evidence in Australia and internationally that racism is a factor impacting significantly on the health of First Peoples and other racialised minorities. Recent policy changes in Australia have required health professionals to integrate cultural safety into their practice to mitigate racism and improve the health of older First Nations Australians and older people from diverse ethnic and cultural groups.

METHODS

This review consisted of literature published in English from 1990, including published primary studies; systematic, integrative and narrative reviews; meta-analyses; theses; policy documents; guidelines; position statements; and government literature. Ovid (MEDLINE), CINAHL Plus with Full Text, Scopus, Proquest Nursing and Allied Health Database, and Informit were used in the full search. The most recent search of all databases was undertaken on 9 May 2022. Ten papers were included in the review, following the exclusion of 376 papers. A title and abstract search of the reference lists of papers included in the review identified no additional papers.

RESULTS

Ten papers were included in the review from Australia, Canada, the US, Norway and England. The literature reviewed suggests that health professionals in the aged care sector in regional, rural and remote areas in Australia, Canada, the US, Norway and England use alternative terms to 'racism' and 'racist', such as 'institutional marginalisation'.

DISCUSSION

The absence of explicit reference to racism aligns with critical race research that argues implicit bias and institutional racism are often separated from an individualised understanding of racism. That is, practitioners may understand racism as something that is perpetrated by individuals in an otherwise 'neutral' health setting. There is also a lack of clarity on how culturally safe care is understood, even though individual care plans are viewed as instrumental in establishing the needs and preferences of the consumers. Within the literature surveyed, barriers to providing quality and culturally inclusive care include disengaged management, insufficient human and material resources, language barriers and a lack of education focused on the needs of older individuals and groups with various cultural and spiritual needs. Additionally, the review does not clearly illuminate what health professionals understand to be racist thinking or behaviour and how it is responded to in practice. Likewise, there is limited information about health professionals' understanding of cultural safety and how to provide culturally inclusive care.

CONCLUSION

While work is beginning on developing standards for cultural safety training in an Australian context, there are also opportunities to consider how these should be applied or adapted to residential and community aged care to best meet the needs of a diverse consumer base and workforce.

Interprofessional Education in Child Protection for Preservice Health and Allied Health Professionals: A Scoping Review

Health and allied health professionals are uniquely positioned to collaborate in prevention, early intervention and responses to child maltreatment. Effective collaboration requires comprehensive interprofessional education (IPE), and inadequate collaboration across sectors and professions continually contributes to poor outcomes for children. Little is known about what interprofessional preparation health and allied health professionals receive before initial qualification (preservice) that equips them for interprofessional collaboration and provision of culturally safe care in child protection. This scoping review aimed to identify what is known internationally about IPE in child protection for preservice health and allied health professionals. Thirteen manuscripts reporting 12 studies met the inclusion criteria and were included in the synthesis. Key characteristics of the educational interventions are presented, including target disciplines, core content and their learning objectives and activities. Findings demonstrated primarily low-quality methodologies and educational interventions that had not been replicated beyond their initial context. Many educational interventions did not provide comprehensive content covering the spectrum of prevention, early intervention and responses for all types of child maltreatment, and/or did not clearly indicate how IPE was achieved. Key challenges to delivering comprehensive interprofessional child protection include lack of institutional support and competing priorities across disciplines who must meet requirements of separate regulatory bodies. Consequently, there is a need for further development and robust evaluation of educational interventions to explore how interprofessional collaborative skills for child protection can be developed and delivered in preservice health and allied health professional education.

Dientamoeba fragilis associated with microbiome diversity changes in acute gastroenteritis patients

This study examined the correlation between intestinal protozoans and the bacterial microbiome in faecal samples collected from 463 patients in New Zealand who were diagnosed with gastroenteritis. In comparison to traditional microscopic diagnosis methods, Multiplexed-tandem PCR proved to be more effective in detecting intestinal parasites. Among the identified protozoans, Blastocystis sp. and Dientamoeba fragilis were the most prevalent. Notably, D. fragilis was significantly associated with an increase in the alpha-diversity of host prokaryotic microbes. Although the exact role of Blastocystis sp. and D. fragilis as the primary cause of gastroenteritis remains debatable, our data indicates a substantial correlation between these protozoans and the prokaryote microbiome of their hosts, particularly when compared to other protists or patients with gastroenteritis but no detectable parasitic cause. These findings underscore the significance of comprehending the contributions of intestinal protozoans, specifically D. fragilis, to the development of gastroenteritis and their potential implications for disease management.

From farm sustainability to ecosystem sustainability: Exploring the limitations of farm-applied aquaculture eco-certification schemes

Aquaculture eco-certification schemes provide standards against which individual farms are assessed, and those farms that comply with eco-certification criteria receive certified status. These schemes aim to improve aquaculture sustainability, but the site-by-site approach of eco-certification can be a barrier to the inclusion of ecosystem perspectives in the evaluation of farm sustainability. However, the ecosystem approach to aquaculture demands a management approach that considers broader scale ecosystem impacts. This study explored how eco-certification schemes and processes account for potential ecosystem impacts of salmon farms. Interviews with eco-certification auditors, salmon producers, and eco-certification staff were conducted. The experience of participants and information from eco-certification scheme criteria and other eco-certification scheme documents were used to identify thematic challenges associated with the consideration of ecosystem impacts including: assessing far-field impacts, managing cumulative effects, and anticipating ecosystem risks. Results indicate that eco-certification schemes work within the limitations of farm-scale application of global eco-certification standards to address potential ecosystem impacts by: (1) including eco-certification scheme criteria that address ecosystem impacts, (2) relying on the experience, expertise, and judgement of eco-certification auditors, and (3) referencing and deferring to local regulations. Results indicate that eco-certification schemes can address ecosystem impacts to some degree, despite their site-by-site approach. The integration of additional tools while supporting the capacity of farms to apply those tools, as well as increasing transparency during compliance assessment could help eco-certification schemes shift from providing assurance of farm sustainability to providing assurance of ecosystem sustainability.

Racially minoritized people’s experiences of racism during COVID-19 in Australia: A qualitative study

OBJECTIVE

Drawing from a broader study exploring how New South Wales community members from racially minoritized backgrounds experienced living through a pandemic, this paper reports specifically on experiences of racism during the COVID-19 pandemic in 2020.

METHODS

Using an in-depth, qualitative interpretive approach, 11 semi-structured interviews and one focus group hosting three participants (n=14) were held via an online videoconferencing platform from September to December 2020. Inductive thematic analysis was undertaken using QRS NVivo as a data management tool.

RESULTS

Racism was heightened during the pandemic and experienced in various ways by racially minoritized peoples in New South Wales. All participants in this research cited experiences of racism that impacted their wellbeing during COVID-19. These experiences are represented by the following four themes: experiencing racism is common; how racisms are experienced; increased fear of racism during COVID-19; and ways of coping with racisms.

CONCLUSIONS

Racism was heightened during the pandemic and generated fear and anxiety that prevented racially minoritized peoples from participating in everyday life.

IMPLICATIONS FOR PUBLIC HEALTH

Messaging from broader public platforms must be harnessed to stop the spread of moral panic so that during times of pandemic, public health strategies need only confirmation, not creation.

The mental health impact of COVID-19 on pre-registration nursing students in Australia: Findings from a national cross-sectional study

AIM

The study aimed to measure and describe the mental health impact of COVID-19 on Australian pre-registration nursing students.

BACKGROUND

The COVID -19 pandemic has had a swift and significant impact on nursing students across the globe. The pandemic was the catalyst for the closure of schools and universities across many countries. This necessary measure caused additional stressors for many students, including nursing students, leading to uncertainty and anxiety. There is limited evidence available to identify the mental health impact of COVID-19 on Australian pre-registration nursing students currently.

DESIGN

A cross-sectional study was conducted across 12 Australian universities.

METHODS

Using an anonymous, online survey students provided demographic data and self-reported their stress, anxiety, resilience, coping strategies, mental health and exposure to COVID-19. Students' stress, anxiety, resilience, coping strategies and mental health were assessed using the Impact of Event Scale-Revised, the Coronavirus Anxiety Scale, the Brief Resilience Scale, the Brief Cope and the DASS-21. Descriptive and regression analyses were conducted to investigate whether stress, anxiety, resilience and coping strategies explained variance in mental health impact. Ethical Approval was obtained from the University of New England Human Research Ethics Committee (No: HE20-188). All participating universities obtained reciprocal approval.

RESULTS

Of the 516 students who completed the survey over half (n = 300, 58.1%) reported mental health concerns and most students (n = 469, 90.9%) reported being impacted by COVID-19. Close to half of students (n = 255, 49.4%) reported signs of post-traumatic stress disorder. Mental health impact was influenced by students' year level and history of mental health issues, where a history of mental health and a higher year level were both associated with greater mental health impacts. Students experienced considerable disruption to their learning due to COVID-19 restrictions which exacerbated students' distress and anxiety. Students coped with COVID-19 through focusing on their problems and using strategies to regulate their emotions and adapt to stressors.

CONCLUSION

The COVID-19 pandemic has considerably impacted pre-registration nursing students' mental health. Strategies to support nursing students manage their mental health are vital to assist them through the ongoing pandemic and safeguard the recruitment and retention of the future nursing workforce.

IMPACT STATEMENT

This study adds an Australian understanding to the international evidence that indicates student nurses experienced a range of negative psychosocial outcomes during COVID-19. In this study, we found that students with a pre-existing mental health issue and final-year students were most affected. The changes to education in Australian universities related to COVID-19 has caused distress for many nursing students. Australian nursing academics/educators and health service staff need to take heed of these results as these students prepare for entry into the nursing workforce.

PATIENT OR PUBLIC INVOLVEMENT

The study was designed to explore the impact of COVID-19 on the mental health of undergraduate nursing students in Australia. Educators from several universities were involved in the design and conduct of the study. However, the study did not include input from the public or the intended participants.

A call for culture-centred care: exploring health workers' perspectives of positive care experiences and culturally responsive care provision to Aboriginal women and their infants in mainstream health in South Australia

BACKGROUND

Aboriginal women and their infants experience significant disadvantage in health outcomes compared to their non-Aboriginal counterparts. Access to timely, effective, and appropriate maternal and child health care can contribute to reducing these existing health disparities. This research sought to explore factors that contribute to continuity of care for Aboriginal women and their infants living in metropolitan South Australia. This paper reports on the perspectives of health care workers in mainstream health services from the antenatal period to the end of an infants' second birthday. It explores health workers' perspectives of what contributes to positive care experiences and satisfaction with care provided to Aboriginal women and their infants in mainstream health.

METHODS

Eight focus groups were held with 52 health professionals. Participants included Aboriginal Cultural Child and Family Support Consultants (n = 7), Aboriginal Maternal Infant Care Workers (n = 3), Midwives (n = 3) and Child and Family Nurses (n = 39). Data was inductively coded and thematically analysed.

RESULTS

Three key themes emerged: the system takes priority, culture is not central in approaches to care, and 'we've got to be allowed to do it in a different way'.

CONCLUSIONS

This research highlights a lack of continuity of care for Aboriginal families accessing mainstream health services from the antenatal period through to an infants' first 1000 days of life. This research has implications for communities, and it calls for strategies to enhance continuity, and healthcare services to provide appropriate and culturally safe care. Findings will inform and guide future changes to improve continuity of care for Aboriginal families and infants in the first 1000 days.

Patient journey mapping to investigate quality and cultural safety in burn care for Aboriginal and Torres Strait Islander children and families - development, application and implications

BACKGROUND

Quality and safety in Australian healthcare is inequitably distributed, highlighted by gaps in the provision of quality care for Aboriginal and Torres Strait Islander children. Burns have potential for long-term adverse outcomes, and quality care, including culturally safe care, is critical to recovery. This study aimed to develop and apply an Aboriginal Patient Journey Mapping (APJM) tool to investigate the quality of healthcare systems for burn care with Aboriginal and Torres Strait Islander children.

STUDY DESIGN

Interface research methodology, using biomedical and cultural evidence, informed the modification of an existing APJM tool. The tool was then applied to the journey of one family accessing a paediatric tertiary burn care site. Data were collected through yarning with the family, case note review and clinician interviews. Data were analysed using Emden's core story and thematic analysis methods. Reflexivity informed consideration of the implications of the APJM tool, including its effectiveness and efficiency in eliciting information about quality and cultural safety.

RESULTS

Through application of a modified APJM tool, gaps in quality care for Aboriginal and Torres Strait Islander children and families were identified at the individual, service and system levels. Engagement in innovative methodology incorporating more than biomedical standards of care, uncovered critical information about the experiences of culturally safe care in complex patient journeys.

CONCLUSION

Based on our application of the tool, APJM can identify and evaluate specific aspects of culturally safe care as experienced by Aboriginal and Torres Strait Islander peoples and be used for quality improvement.

Atrioventricular nodal ablation with pacemaker implant is associated with improved safety outcomes compared to pulmonary vein isolation of atrial fibrillation with heart failure

Background

Pulmonary vein isolation (PVI) and atrioventricular nodal ablation (AVNA) with pacemaker implant have both been advocated for patients with atrial fibrillation (AF) and heart failure with reduced ejection fraction (HFrEF). Direct comparisons between the two are limited.

Purpose

We sought to compare outcomes and complications following PVI versus AVNA with implant of a cardiac implantable electronic device (CIED) among patients with AF and HFrEF.

Methods

We queried the National Inpatient Sample from 2011 to 2019, using relevant ICD-9 and -10 diagnostic and procedural codes for AF, HFrEF, ablation, and CIED implant to identify our study cohort. Exclusion criteria included presence of a pre-existing CIED, ventricular arrhythmias, non-AF supraventricular arrhythmias, and surgical AF ablation. Baseline characteristics included age, sex, race, and comorbidities related to AF and cardiovascular disease. Severity of comorbidities was assessed via Deyo-Charlson Comorbidity Index (Deyo-CCI). Outcomes investigated include all-cause mortality, major adverse cardiovascular events (MACE), extra-cardiac procedural complications, length of stay, and total hospital charges. Outcomes associations were analyzed using multivariate logistic regression adjusted for baseline characteristics that were significantly different (P<0.05) between cohorts expressed as adjusted odds ratios (aOR) and 95% confidence intervals (CI). SPSS v28.0 (IBM, Armonk, NY) was used to carry out all calculations.

Results

We identified 3,565 encounters for PVI and 1,355 for AVNA with CIED implant among hospitalized patients with AF and HFrEF. Patients who underwent AVNA were more often older (73.8 vs 66.2 years), with more severe comorbidities (mean Deyo-CCI score 2.9 vs 2.6) and were more likely to have an emergent procedure performed (81.3% vs 69.7%; p<0.001 for all). However, the AVNA cohort had less mortality (0.5% vs 1.2%, p=0.03), MACE (6.1% vs 7.8%, p=0.04), and total complications (12.7% vs 16.3%, p=0.002), but longer hospital stay (8.0 vs 6.5 days) and higher total charges ($201,100 vs $159,382; p<0.001 for both). After adjusting for confounders, AVNA remained independently associated with decreased odds of mortality (aOR: 0.370; 95% CI [0.159–0.862], p=0.02), MACE (aOR: 0.552; 95% CI [0.420–0.726], p<0.001), and total complications (aOR: 0.708; 95% CI [0.589–0.852], p<0.001).

Conclusion

Despite older age with more severe comorbidities and less elective procedures, hospitalized patients with AF and HFrEF who underwent AVNA with CIED implant had improved safety outcomes compared to PVI. Further studies comparing the intermediate and long-term outcomes and efficacy between therapies are needed to better delineate which would best serve this population.

Assessing outcomes following catheter ablation of ventricular tachycardia in patients with durable left ventricular assist devices

Background

Management of ventricular tachycardia (VT) after implant of a durable left ventricular assist device (LVAD) is challenging, without consensus on optimal therapy. Multiple small studies have examined catheter ablation of VT in these patients with low reported incidence of complications.

Purpose

We sought to evaluate periprocedural outcomes following VT ablation among LVAD recipients.

Methods

We queried the National Inpatient Sample from 2011 to 2019 to conduct our study. Baseline characteristics include age, sex, race, and comorbidities related to cardiovascular disease. Comorbidity severity was assessed using the Deyo-Charlson Comorbidity Index (Deyo-CCI). Patients with any supraventricular arrhythmias were excluded. Outcomes investigated include heart transplant procedure, all-cause mortality, major adverse cardiovascular events (MACE), and periprocedural complications. Multivariate regression was used to analyze outcomes associations adjusted for baseline characteristics that were significantly different (P<0.05) between cohorts expressed as adjusted odds ratios (aOR) and 95% confidence intervals (CI). SPSS v28.0 (IBM, Armonk, NY) was used to carry out all calculations.

Results

We identified 56 patients who underwent ablation among 2,202 LVAD recipients hospitalized for VT. Patients who underwent ablation were more likely to have ischemic cardiomyopathy (33.9% vs. 22.2%, p=0.03) or an automated implantable cardioverter-defibrillator (55.4% vs 34.3%, p=0.001). There were otherwise no significant differences between cohorts (mean Deyo-CCI score of 2.3 for both, p=0.48). Between those who did and did not undergo ablation, there were no significant differences in heart transplant (5.4 vs 5.0%, p=0.9), mortality (7.1% vs 7.0%, p=0.96), total strokes (3.6% vs 5.0%, p=0.48), myocardial infarction (3.6% vs 4.6%, p=0.71), overall MACE (8.9% vs 10.2%, p=0.26) or total complications (35.7% vs 41.9%, p=0.35). There were no incidents of pump thrombosis in the ablation group, but 92 events (4.3%) were found in the medical therapy group. Multivariate analysis affirmed no significant association between ablation and mortality (aOR 1.277, CI [0.450–3.629]), MACE (aOR 1.125, CI [0.436–2.902]), or total complications (aOR 0.932, CI [0.528–1.645]).

Conclusion

Overall complications following VT ablation among LVAD patients were higher than previously reported but no statistically significant differences were found compared to conservative management. While ablation appears safe to perform, particularly among those with structural heart disease and ischemic cardiomyopathy, longer duration studies are needed to determine the efficacy of this procedure.

Gender disparities in ventricular tachycardia: evaluating clinical outcomes and interventions

Background

Gender differences in the etiology of ventricular arrhythmia are well-known and can potentially affect clinical outcomes. Women have been under-represented in studies investigating ventricular tachycardia (VT). Thus, gender differences in clinical outcomes of VT are poorly defined.

Purpose

We sought to elucidate the clinical outcomes and interventions among women with VT.

Methods

We used the National Inpatient Sample to identify patients aged 18 and older admitted with VT from 2011 to 2019. Observations missing data on age, sex and mortality were excluded. Baseline characteristics include age, race, and comorbidities related to cardiovascular disease. Severity of comorbidities was assessed via the Deyo-Charlson Comorbidity Index (Deyo-CCI) score. Outcomes investigated include all-cause mortality, major adverse cardiovascular events (MACE), and incidence of catheter ablation, cardioversion, and automated implantable cardioverter defibrillator (AICD) insertion. Gender and outcomes association were analyzed using multivariable logistic regression adjusted for baseline characteristics that were significantly different (P<0.05) between cohorts expressed as adjusted odds ratios (aOR) and 95% confidence intervals (CI). SPSS v28.0 (IBM, Armonk, NY) was used to carry out all calculations.

Results

Between 2011 and 2019, there were an estimated 3,544,445 hospital admissions for VT, of which, 33.8% were women, who were more likely to be older (69.2 vs 68.0 years) and of minority descent (30.3% vs 26.7%) compared to men. Women were less likely to have coronary artery disease (43.5% vs 62.2%) or ischemic cardiomyopathy (5.0% vs 11.9%) and had a lower mean Deyo-CCI score (2.2 vs 2.4; p<0.001 for all). Women had a higher incidence of mortality (10.6% vs 9.2%) and ischemic stroke (5.3% vs 4.5%), but less acute coronary syndrome (17.6% vs 21.4%; p<0.001 for all). Overall incidence of MACE was lower among women (28.6% vs 31.4%; p<0.001). Multivariate regression analysis demonstrated that female sex remained independently associated with increased odds for all-cause mortality (aOR: 1.089; 95% CI: [1.062–1.116], p<0.001) although decreased odds for MACE (aOR: 0.952; 95% CI: [0.939–0.965]). Female sex was also independently associated with decreased odds for cardioversion (aOR: 0.936; 95% CI: [0.910–0.963]), AICD insertion, (aOR: 0.737; 95% CI: [0.711–0.764]) and ablation (aOR: 0.806; 95% CI: [0.766–0.847]; all p<0.001).

Conclusion

In this retrospective analysis of patients hospitalized with VT, women had less coronary artery disease and less MACE, yet all-cause mortality was higher. Female sex was also independently associated with fewer interventions, including AICD insertion and ablation. Although there are gender differences in risk factors and causes of VT, this does not fully explain disparities in care and outcomes. Further studies are needed to explore and elucidate these gender disparities.

Measurement properties of the WHO Disability Assessment Schedule 2.0 for evaluating functional status after inpatient surgery

BACKGROUND

Expert recommendations propose the WHO Disability Assessment Schedule (WHODAS) 2.0 as a core outcome measure in surgical studies, yet data on its long-term measurement properties remain limited. These were evaluated in a secondary analysis of the Measurement of Exercise Tolerance before Surgery (METS) prospective cohort.

METHODS

Participants were adults (40 years of age or older) who underwent inpatient non-cardiac surgery. The 12-item WHODAS and EQ-5DTM-3L questionnaires were administered preoperatively (in person) and 1 year postoperatively (by telephone). Responsiveness was characterized using standardized response means (SRMs) and correlation coefficients between change scores. Construct validity was evaluated using correlation coefficients between 1-year scores and comparisons of WHODAS scores across clinically relevant subgroups.

RESULTS

The analysis included 546 patients. There was moderate correlation between changes in WHODAS and various EQ-5DTM subscales. The strongest correlation was between changes in WHODAS and changes in the functional domains of the EQ-5D-3L-for example, mobility (Spearman's rho 0.40, 95 per cent confidence interval [c.i.] 0.32 to 0.48) and usual activities (rho 0.45, 95 per cent c.i. 0.30 to 0.52). When compared across quartiles of EQ-5D index change, median WHODAS scores followed expected patterns of change. In subgroups with expected functional status changes, the WHODAS SRMs ranged from 'small' to 'large' in the expected directions of change. At 1 year, the WHODAS demonstrated convergence with the EQ-5D-3L functional domains, and good discrimination between patients with expected differences in functional status.

CONCLUSION

The WHODAS questionnaire has construct validity and responsiveness as a measure of functional status at 1 year after major surgery.

Child and family health nurses' roles in the care of infants and children: A scoping review

Child and family health nurses (CFHNs) work in a variety of settings with families to promote optimal growth and development in infants and children from birth to 5 years. Literature is available about models of care that CFHNs use in their work, but there is limited information about how CFHNs enact care specifically for infants and children. The aim of this scoping review was to identify and contextualize existing knowledge of how CFHNs, both in Australia and internationally, care for infants and children. Arksey and O'Malley's (2005) framework was used to review 27 studies from Australia, Sweden, Finland, United Kingdom (UK), United States of America (USA), Ireland, Netherlands, Denmark and Canada. It was identified that CFHNs, equipped with a range of assessment tools for early intervention and health promotion, use a partnership approach when working with parents to promote the health and well-being of infants and children. The literature revealed the complexity of the roles undertaken by CFHNs when caring for infants and children. Review findings indicated that CFHNs' work is distinctive because it is conducted in home and community settings, is relational and salutogenic in nature and is also located in the domain of preventative health and early intervention.

Micromolar Metabolite Measurement in an Electronically Multiplexed Format

The detection of metabolites such as choline in blood are important in clinical care for patients with cancer and cardiovascular disease. Choline is only present in human blood at low concentrations hence accurate measurement in an affordable point-of-care format is extremely challenging. Integration of microfluidics on to complementary metal-oxide semiconductor (CMOS) technology has the potential to enable advanced sensing technologies with extremely low limit of detection that are well suited to multiple clinical metabolite measurements. Although CMOS and microfluidics are individually mature technologies, their integration has presented challenges that we overcome in a novel, cost-effective, single-step process. To demonstrate the process, we present the microfluidic integration of a metabolomics-on-CMOS point-of-care platform with four capillary microfluidic channels on top of a CMOS optical sensor array. The fabricated device was characterised to verify the required structural profile, mechanical strength, optical spectra, and fluid flow. As a proof of concept, we used the device for the in-vitro quantification of choline in human blood plasma with a limit of detection of 3.2 M and a resolution of 1.6 M.

Pandemic-related racial discrimination and its health impact among non-Indigenous racially minoritized peoples in high-income contexts: a systematic review

This study aims to review articles reporting the perspectives and experiences of pandemic-related discrimination among racially minoritized peoples in high-income contexts. We searched online databases (Medline, EMBASE, PsycINFO, Web of Science, and ProQuest) for peer-reviewed articles published between January 2002 and October 2020. Eligible studies reported either quantitative or qualitative accounts of pandemic-related discrimination from the perspectives of racially minoritized peoples in high-income contexts. Two authors screened 30% of titles/abstracts, and all full-text articles. Each article included for extraction underwent a quality assessment by two reviewers. Data were extracted and categorized thematically using NVivo 12, followed by a secondary analysis informed by critical race theory. Of the 1289 articles screened, 16 articles from five countries met the inclusion criteria. Racial discrimination is heightened during pandemic periods, due to the social association of specific racial groups with pandemic diseases including COVID-19, SARS (Asian), H1N1 (Hispanic) and Ebola (African). Fear based responses to racially minoritized peoples during pandemic periods included verbal/physical abuse, hypersurveillance, and avoidance, often occurring in public spaces. Pandemic-related racism had subsequent impacts on mental health and health care accessibility. Various coping strategies, including community support, avoidance, and problem solving, were documented in response to racial discrimination. Racialized discrimination and violence is a serious threat to the health and wellbeing of racially minoritized peoples, particularly due to its increase during pandemic periods. Racism must be recognized as a public health issue, and efforts to address its increased impact in pandemic contexts should be made, including ensuring that adequate representation of racially minoritized groups is present in policy, planning, and implementation.

Differences in obstetrical care and outcomes associated with the proportion of the obstetrician's shift completed

BACKGROUND

Understanding and improving obstetrical quality and safety is an important goal of professional societies, and many interventions such as checklists, safety bundles, educational interventions, or other culture changes have been implemented to improve the quality of care provided to obstetrical patients. Although many factors contribute to delivery decisions, a reduced workload has addressed how provider issues such as fatigue or behaviors surrounding impending shift changes may influence the delivery mode and outcomes.

OBJECTIVE

The objective was to assess whether intrapartum obstetrical interventions and adverse outcomes differ based on the temporal proximity of the delivery to the attending's shift change.

STUDY DESIGN

This was a secondary analysis from a multicenter obstetrical cohort in which all patients with cephalic, singleton gestations who attempted vaginal birth were eligible for inclusion. The primary exposure used to quantify the relationship between the proximity of the provider to their shift change and a delivery intervention was the ratio of time from the most recent attending shift change to vaginal delivery or decision for cesarean delivery to the total length of the shift. Ratios were used to represent the proportion of time completed in the shift by normalizing for varying shift lengths. A sensitivity analysis restricted to patients who were delivered by physicians working 12-hour shifts was performed. Outcomes chosen included cesarean delivery, episiotomy, third- or fourth-degree perineal laceration, 5-minute Apgar score of <4, and neonatal intensive care unit admission. Chi-squared tests were used to evaluate outcomes based on the proportion of the attending's shift completed. Adjusted and unadjusted logistic models fitting a cubic spline (when indicated) were used to determine whether the frequency of outcomes throughout the shift occurred in a statistically significant, nonlinear pattern RESULTS: Of the 82,851 patients eligible for inclusion, 47,262 (57%) had ratio data available and constituted the analyzable sample. Deliveries were evenly distributed throughout shifts, with 50.6% taking place in the first half of shifts. There were no statistically significant differences in the frequency of cesarean delivery, episiotomy, third- or fourth-degree perineal lacerations, or 5-minute Apgar scores of <4 based on the proportion of the shift completed. The findings were unchanged when evaluated with a cubic spline in unadjusted and adjusted logistic models. Sensitivity analyses performed on the 22.2% of patients who were delivered by a physician completing a 12-hour shift showed similar findings. There was a small increase in the frequency of neonatal intensive care unit admissions with a greater proportion of the shift completed (adjusted P=.009), but the findings did not persist in the sensitivity analysis.

CONCLUSION

Clinically significant differences in obstetrical interventions and outcomes do not seem to exist based on the temporal proximity to the attending physician's shift change. Future work should attempt to directly study unit culture and provider fatigue to further investigate opportunities to improve obstetrical quality of care, and additional studies are needed to corroborate these findings in community settings.

Considering difference: clinician insights into providing equal and equitable burns care for Aboriginal and Torres Strait Islander children

OBJECTIVE

To better understand issues driving quality in burn care related to equity of outcomes and equality of provision for Aboriginal and Torres Strait Islander children.

METHODS

Seventy-six interviews with team members who provide care for Aboriginal and Torres Strait Islander children in six paediatric burn units across five Australian jurisdictions were completed. Interface research methodology within a qualitative design guided data collection and analysis.

RESULTS

Three themes were identified: i) Burn team members who identify the requirement to meet the specific needs of Aboriginal and Torres Strait Islander children and deliver differential care; ii) Burn team members who believe in equal care, but deliver differential care based on the specific needs of Aboriginal and Torres Strait Islander children; and iii) Burn team members who see little need for provision of differential care for Aboriginal and Torres Strait Islander children and rather, value the provision of equal care for all.

CONCLUSION

Burn team members conflate equitable and equal care, which has implications for the delivery of care for Aboriginal and Torres Strait Islander children. Equitable care is needed to address disparities in post-burn outcomes, and this requires clinicians, healthcare services and relevant system structures to work coherently and intentionally to reflect these needs. Implications for public health: Changes in health policy, the embedding of Aboriginal and Torres Strait Islander liaison officers in burn care teams and systems that prioritise critical reflexive practice are fundamental to improving care.

An analysis of the spatio-temporal occurrence of anthelmintic veterinary drug residues in groundwater

Anthelmintics are antiparasitic drugs used to control helminthic parasites such as nematodes and trematodes in animals, particularly those exposed through pasture-based production systems. Even though anthelmintics have been shown to be excreted into the environment in relatively high amounts as unmetabolized drug or transformation products (TPs), there is still only limited information available on their environmental occurrence, particularly in groundwater, which has resulted in them being considered as potential emerging contaminants of concern. A comprehensive study was carried out to investigate the occurrence of 40 anthelmintic residues (including 13 TPs) in groundwaters (and associated surface waters) throughout the Republic of Ireland. The study focused on investigating the occurrence of these contaminants in karst and fractured bedrock aquifers, with a total of 106 sites (88 groundwaters and 18 surface waters) samples during spring 2017. Seventeen anthelmintic compounds consisting of eight parent drugs and nine TPs were detected at 22% of sites at concentrations up to 41 ng L^-1. Albendazole and its TPs were most frequently detected residues, found at 8% of groundwater sites and 28% of surface water sites. Multivariate statistical analysis identified several source and pathway factors as being significantly related to the occurrence of anthelmintics in groundwater, however there was an evident localised effect which requires further investigation. An investigation of the temporal variations in occurrence over a 13 month period indicated a higher frequency and concentration of anthelmintics during February/March and again later during August/September 2018, which coincided with periods of increased usage and intensive meteorological events. This work presents the first detections of these contaminants in Irish groundwater and it contributes to broadening our understanding of anthelmintics in the environment. It also provides insight to seasonal trends in occurrence, which is critical for assessing potential future effects and implications of climate change.

Health care provider's perceptions of factors that influence infant mortality in Papua Indonesia: A qualitative study

BACKGROUND

High infant mortality remains a global health problem, particularly in less developed countries. Indonesia has one of the highest infant mortality rates in Southeast Asia. Known factors relate to documented medical conditions and do not necessarily explain their origin.

AIM

To identify and explore factors that contribute to infant mortality in Papua, Indonesia, through the lens of health workers' perceptions.

METHODS

A qualitative descriptive approach using semi-structured interviews was used. Twelve Indonesian health workers participated. Interviews were audio-recorded and transcribed, and then analysed thematically.

FINDINGS

Five main themes were generated: beliefs and practices related to pregnancy, birth, and infants; infant health factors; maternal health factors; barriers to seeking, receiving and providing infant health care; and enablers and strategies for improving infant health.

DISCUSSION

Cultural factors were perceived as contributing to poor health outcomes by shaping decisions, help seeking behaviour and health care access. Poverty, health literacy, road access and transport, shortage of health staffing, and health equipment and medicines exacerbate poor health outcomes.

CONCLUSION

Cultural knowledge and sensitivity are central to the provision and acceptance of health care by local families in Papua, Indonesia. Recommendations include: improving cultural sensitivity and cultural safety of service; implementing community health promotion to enhance maternal and infant health; improving community participation in health care planning and delivery; and enhancing collaboration between national, provincial, regency and local governments.

Bionematicides as an alternative to methyl bromide fumigation

Fumigant use in perennial crops can be reduced through prolonging the life of existing orchards. The longer an orchard remains healthy and productive, the less often it will be terminated, fumigated, and replanted. Two trials were conducted to determine the effectiveness of DiTera, a toxin produced by the fungus (Myrothecium verrucaria) and Nema-Q, an extract of the soap bark tree (Quillaja saponaria) for management of root-lesion (Pratylenchus vulnus) and ring (Mesocriconema xenopla) nematodes on walnuts. In the first trial, spring and fall treatments of DiTera were applied each year for four years to variety ‘Chandler’ scion on seedling ‘Paradox’ rootstock, and to own-rooted ‘Chandler’ trees. On ‘Paradox’ rootstock, both DiTera and Nema-Q increased walnut yields (P ≤ 0.05) and produced more vigorous trees (P ≤ 0.05) without significant reductions in nematode populations (P ≤ 0.05). A second trial was conducted with three rates of DiTera and four rates of Nema-Q, combinations of the two products, and an untreated control on ‘Chandler’ scion on ‘Paradox’ rootstock. The highest rate of Nema-Q (P ≤ 0.05), and a combination treatment of DiTera plus Nema-Q (P ≤ 0.05) increased trunk circumference. Several treatments showed reductions in root-lesion and ring nematodes (P ≤ 0.05). Bionematicides can improve yield, growth, and vigor in walnut orchards infested with plant-parasitic nematodes.

"They Are Worth Their Weight in Gold": Families and Clinicians' Perspectives on the Role of First Nations Health Workers in Paediatric Burn Care in Australia

Burns affect Australia’s First Nations children more than other Australian children, they also experience longer lengths of stay in tertiary burns units and face barriers in accessing burn aftercare treatment. Data sets from two studies were combined whereby 19 families, 11 First Nations Health Worker (FNHW) and 56 multidisciplinary burn team members from across Australia described the actual or perceived role of FNHW in multidisciplinary burn care. Data highlighted similarities between the actual role of FNHW as described by families and as described by FNHW such as enabling cultural safety and advocacy. In contrast, a disconnect between the actual experience of First Nations families and health workers and that as perceived by multidisciplinary burn team members was evident. More work is needed to understand the impact of this disconnect and how to address it.

An investigation of anticoccidial veterinary drugs as emerging organic contaminants in groundwater

Intensification of the food production system to meet increased global demand for food has led to veterinary pharmaceuticals becoming a critical component in animal husbandry. Anticoccidials are a group of veterinary products used to control coccidiosis in food-producing animals, with primary prophylactic use in poultry production. Excretion in manure and subsequent land-spreading provides a potential pathway to groundwater. Information on the fate and occurrence of these compounds in groundwater is scant, therefore these substances are potential emerging organic contaminants of concern. A study was carried out to investigate the occurrence of anticoccidial compounds in groundwater throughout the Republic of Ireland. Twenty-six anticoccidials (6 ionophores and 20 synthetic anticoccidials) were analysed at 109 sites (63 boreholes and 46 springs) during November and December 2018. Sites were categorised and selected based on the following source and pathway factors: (a) the presence/absence of poultry activity (b) predominant aquifer category and (c) predominant groundwater vulnerability, within the zone of contribution (ZOC) for each site. Seven anticoccidials, including four ionophores (lasalocid, monensin, narasin and salinomycin) and three synthetic anticoccidials (amprolium, diclazuril and nicarbazin), were detected at 24% of sites at concentrations ranging from 1 to 386 ng L^-1. Monensin and amprolium were the two most frequently detected compounds, detected at 15% and 7% of sites, respectively. Multivariate statistical analysis has shown that source factors are the most significant drivers of the occurrence of anticoccidials, with no definitive relationships between occurrence and pathway factors. The study found that the detection of anticoccidial compounds is 6.5 times more likely when poultry activity is present within the ZOC of a sampling point, compared to the absence of poultry activity. This work presents the first detections of these contaminants in Irish groundwater and it contributes to broadening our understanding of the environmental occurrence and fate of anticoccidial veterinary products.

Location and Setting of the Mars InSight Lander, Instruments, and Landing Site

Knowing precisely where a spacecraft lands on Mars is important for understanding the regional and local context, setting, and the offset between the inertial and cartographic frames. For the InSight spacecraft, the payload of geophysical and environmental sensors also particularly benefits from knowing exactly where the instruments are located. A ~30 cm/pixel image acquired from orbit after landing clearly resolves the lander and the large circular solar panels. This image was carefully georeferenced to a hierarchically generated and coregistered set of decreasing resolution orthoimages and digital elevation models to the established positive east, planetocentric coordinate system. The lander is located at 4.502384°N, 135.623447°E at an elevation of -2,613.426 m with respect to the geoid in Elysium Planitia. Instrument locations (and the magnetometer orientation) are derived by transforming from Instrument Deployment Arm, spacecraft mechanical, and site frames into the cartographic frame. A viewshed created from 1.5 m above the lander and the high-resolution orbital digital elevation model shows the lander is on a shallow regional slope down to the east that reveals crater rims on the east horizon ~400 m and 2.4 km away. A slope up to the north limits the horizon to about 50 m away where three rocks and an eolian bedform are visible on the rim of a degraded crater rim. Azimuths to rocks and craters identified in both surface panoramas and high-resolution orbital images reveal that north in the site frame and the cartographic frame are the same (within 1°).

The EVITA evidence action tool to improve evidence-based policymaking for public mental health

The estimated global disease burden of mental illness is 32.4% of years lived with disability. Mental health is a critical determinant for public health, and government-level action is needed for integration of mental health into public health. But in many low/middle-income countries (LMICs) mental health is absent on the policy agenda, despite up to 90% of people with mental illness lacking treatment. Evidence on cost-effective treatments is available, but translation of research into policy is a 'wicked' problem and often fails. We investigate the inter-relationships of research evidence and mental health policymaking in LMICs and present a framework/advocacy tool to guide and support evidence-based public mental health policymaking.

Using a mixed-methods approach, we conducted a systematic review, based on which we developed a provisional framework (EVITA), revised and validated it through expert in-depth interviews. We then empirically tested the EVITA framework against three case studies (provincial, national, global level, South Africa). We collected qualitative data through expert interviews/documentary analysis, coded and analysed the data in NVivo, and finalised the framework and action tool.

We identified agenda-setting as a research theory gap in the context of mental health knowledge translation in LMICs. Thus we developed the EVITA framework for evidence-based mental health policy agenda-setting, and validated it against empirical case studies. Our findings suggest that behavioural methods can support interventions to improve research uptake.

The EVITA action tool has been theoretically and empirically validated, and includes policy agenda-setting and behavioural methods as a novel, effective mechanisms for improving evidence-based policymaking in public mental health. EVITA has the potential to improve the challenging process of research evidence translation into policy/practice in LMICs, and may be applicable to other neglected health areas/countries.

Key messages

The new validated EVITA framework uses agenda-setting and behavioural methods to improve knowledge exchange for better evidence-informed, potentially more effective, public mental health policymaking. The EVITA action tool helps researchers, policymakers & others to strategically take action for public mental health agenda-setting and advocacy interventions for evidence-based policymaking in LMICs.

Associations between postpartum fertility phenotypes and genetic traits in seasonal-calving, pasture-based lactating dairy cows

The objective of this study was to evaluate the associations between corpus luteum (CL) status, uterine health, body condition score (BCS), metabolic status, and parity at wk 3 and 7 postpartum in seasonal-calving, pasture-based, lactating dairy cows. The associations between those phenotypes and individual genetic traits were also evaluated. First- and second-parity spring-calving lactating dairy cows (n = 2,600) from 35 dairy farms in Ireland were enrolled. Farms were visited every 2 weeks; cows that were at wk 3 (range 14 to 27 DIM) and wk 7 (range 42 to 55 DIM) postpartum were examined. Body condition score was measured using a scale of 1 to 5 with 0.25 increments. Transrectal ultrasound examination was performed at wk 3 and 7 postpartum to determine presence or absence of CL and ultrasound reproductive tract score. Blood samples were collected at each visit and the concentrations of glucose, β-hydroxybutyrate (BHB), and fatty acids (FA) were analyzed by using enzymatic colorimetry. Cows were grouped into 3 BCS categories [low (≤2.5), target (≥2.75 and ≤3.25), and high (≥3.5)]; 2 CL status categories: (present or absent); 2 uterine health status (UHS) categories (normal and abnormal); and 3 metabolic status categories [good (high glucose, low fatty acids and BHB), poor (low glucose, high fatty acids and BHB), and moderate (all other combinations)]. Fisher's exact test was used to test associations between variables and was supplemented by logistic regression. We found associations between UHS (wk 3 and 7), BCS (wk 3 and 7), parity (wk 3 and 7) metabolic status (wk 3), and predicted transmitting ability for calving interval (PTA for CIV; wk 3) and CL status. Cows that had abnormal UHS, low BCS, primiparity, and poor metabolic status, and were in the quartile with the greatest PTA for CIV were less likely to have had CL present at wk 3 and 7 postpartum. We also found associations between CL status (wk 3 and 7), BCS (wk 3 and 7), parity (wk 3 and 7), and PTA for CIV (wk 3) and UHS. Cows that did not have a CL present had low BCS, primiparity, and that were in the quartile with greatest PTA for CIV, had a greater risk of abnormal UHS at wk 3 and 7 postpartum. We observed strong associations between CL status, UHS, BCS, metabolic status, parity, and individual genetic traits at wk 3 and 7 postpartum in seasonal-calving, pasture-based lactating dairy cows. Achieving target BCS and good metabolic status, and selecting cows based on PTA for CIV, are all expected to increase the likelihood of hastening the resumption of estrous cyclicity and enhancing uterine health during the postpartum period.

Untangling the Threads: Stakeholder Perspectives of the Legal and Ethical Issues Involved in Preparing Australian Consumers for Commercial Surrogacy Overseas

This article focuses on the complexities of regulating Australians' access to commercial surrogacy overseas. Altruistic surrogacy is allowed in Australia but access to women willing to act as surrogates is limited and many Australians now seek surrogacy arrangements via commercial agencies overseas. This qualitative study interviewed key stakeholders in Australia, including clinicians providing reproductive medicine, lawyers providing legal services, consumer advocates, counsellors and health policy regulators. The aim of the study was to explore perceptions of various experts concerning commercial surrogacy overseas so as to identify issues for the establishment of ethical guidelines and surrogacy policies in Australia. A number of issues relevant to Australians seeking commercial surrogacy overseas were identified and in particular, relating to the level of informed decision-making required by intending parents as well as concerns for the welfare of children born. Amendments to current ethical guidelines and protections for children born and entering Australia are recommended.

Fertility of fresh and frozen sex-sorted semen in dairy cows and heifers in seasonal-calving pasture-based herds

Our objective in this study was to evaluate the reproductive performance of dairy heifers and cows inseminated with fresh or frozen sex-sorted semen (SS) in seasonal-calving pasture-based dairy herds. Ejaculates of 10 Holstein-Friesian bulls were split and processed to provide (1) fresh conventional semen at 3 × 10⁶ sperm per straw (CONV); (2) fresh SS at 1 × 10⁶ sperm per straw (SS-1M); (3) fresh SS semen at 2 × 10⁶ sperm per straw (SS-2M); and (4) frozen SS at 2 × 10⁶ sperm per straw (SS-FRZ). Generalized linear mixed models were used to evaluate the effect of semen treatment and other explanatory variables on pregnancy per artificial insemination (P/AI) in heifers (n = 3,214) and lactating cows (n = 5,457). In heifers, P/AI was greater for inseminations with CONV (60.9%) than with SS-FRZ (52.8%) but did not differ from SS-1M (54.2%) or SS-2M (53.5%). Cows inseminated with CONV had greater P/AI (48.0%) than cows inseminated with SS, irrespective of treatment (SS-1M, SS-2M, and S-FROZEN; 37.6, 38.9, and 40.6%, respectively). None of the SS treatments differed from each other with regard to P/AI in either heifers or cows. The relative performance of SS compared with CONV was also examined [i.e., relative P/AI = (SS P/AI)/(CONV P/AI) × 100]. Frozen SS achieved relative P/AI >84%. Bull affected P/AI in both heifers and cows, but no bull by semen treatment interaction was observed. In heifers, P/AI increased with increasing predicted transmitting ability for milk protein percentage. In cows, P/AI increased with increasing Economic Breeding Index (EBI) and with days in milk (DIM) at AI but decreased with increasing EBI milk subindex, parity and with DIM². Cows in parity ≥5 had the lowest P/AI and differed from cows in parities 1, 2, or 3. Dispatch-to-AI interval of fresh semen did not affect P/AI in lactating cows, but a dispatch-to-AI interval by bull interaction was detected whereby P/AI was constant for most bulls but increased with greater dispatch-to-AI intervals for 2 bulls. In conclusion, frozen SS achieved greater P/AI relative to conventional semen than was previously reported in lactating cows. Fresh SS did not achieve greater P/AI than frozen SS, regardless of whether the sperm dose per straw was 1 × 10⁶ or 2 × 10⁶. A bull effect for all semen treatments, as well as a dispatch-to-AI interval by bull interaction for fresh semen, highlights the importance of using a large team of bulls for breeding management.

How Do Nurses Keep Children Safe From Abuse and Neglect, and Does it Make a Difference? A Scoping Review

OBJECTIVES

To explore the extent of child protection work performed by nurses and identify which interventions hold the strongest evidence for future practice.

DESIGN

This scoping review was guided by Arksey and O'Malley's framework for scoping reviews.

DATA SOURCES

Electronic databases (CINAHL, Medline, Scopus, Web of Science) and grey literature were searched in August 2017. Further studies were identified through manual literature searching.

RESULTS

Forty-one studies from seven countries met the inclusion criteria. The studies showed nurses keep children safe primarily through the prevention of abuse (n = 32), but also through detection of abuse (n = 1) and interventions to mitigate the effects of abuse (n = 8). Nurses' specific interventions most frequently involved post-natal home visiting (n = 20), parent education (n = 10) and assessment and care of children or adolescents following sexual abuse (n = 4). The main findings showed that although nurses did have positive impacts upon some measures of abuse and neglect, results were not consistent across studies. In addition, some studies used indirect measures of abuse and neglect, which may not impact children's experiences of abuse. It is difficult to extrapolate these findings to the broader nursing profession as literature did not accurately represent the range of ways that nurses keep children safe from abuse and neglect.

CONCLUSIONS

This review demonstrated nurses prevent, detect and respond to abuse and neglect in many ways. However, given mixed evidence and absence of some nurse interventions in the literature, further research is needed to represent the range of ways that nurses keep children safe and determine their effectiveness.

Neonatal outcomes of elective early-term births after demonstrated fetal lung maturity

BACKGROUND

Studies of early-term birth after demonstrated fetal lung maturity show that respiratory and other outcomes are worse with early-term birth (37⁰-38⁶ weeks) even after demonstrated fetal lung maturity when compared with full-term birth (39⁰-40⁶ weeks). However, these studies included medically indicated births and are therefore potentially limited by confounding by the indication for delivery. Thus, the increase in adverse outcomes might be due to the indication for early-term birth rather than the early-term birth itself.

OBJECTIVE

We examined the prevalence and risks of adverse neonatal outcomes associated with early-term birth after confirmed fetal lung maturity as compared with full-term birth in the absence of indications for early delivery.

STUDY DESIGN

This is a secondary analysis of an observational study of births to 115,502 women in 25 hospitals in the United States from 2008 through 2011. Singleton nonanomalous births at 37-40 weeks with no identifiable indication for delivery were included; early-term births after positive fetal lung maturity testing were compared with full-term births. The primary outcome was a composite of death, ventilator for ≥2 days, continuous positive airway pressure, proven sepsis, pneumonia or meningitis, treated hypoglycemia, hyperbilirubinemia (phototherapy), and 5-minute Apgar <7. Logistic regression and propensity score matching (both 1:1 and 1:2) were used.

RESULTS

In all, 48,137 births met inclusion criteria; the prevalence of fetal lung maturity testing in the absence of medical or obstetric indications for early delivery was 0.52% (n = 249). There were 180 (0.37%) early-term births after confirmed pulmonary maturity and 47,957 full-term births. Women in the former group were more likely to be non-Hispanic white, smoke, have received antenatal steroids, have induction, and have a cesarean. Risks of the composite (16.1% vs 5.4%; adjusted odds ratio, 3.2; 95% confidence interval, 2.1-4.8 from logistic regression) were more frequent with elective early-term birth. Propensity scores matching confirmed the increased primary composite in elective early-term births: adjusted odds ratios, 4.3 (95% confidence interval, 1.8-10.5) for 1:1 and 3.5 (95% confidence interval, 1.8-6.5) for 1:2 matching. Among components of the primary outcome, CPAP use and hyperbilirubinemia requiring phototherapy were significantly increased. Transient tachypnea of the newborn, neonatal intensive care unit admission, and prolonged neonatal intensive care unit stay (>2 days) were also increased with early-term birth.

CONCLUSION

Even with confirmed pulmonary maturity, early-term birth in the absence of medical or obstetric indications is associated with worse neonatal respiratory and hepatic outcomes compared with full-term birth, suggesting relative immaturity of these organ systems in early-term births.

Rationale and development of a business case for antimicrobial stewardship programs in acute care hospital settings

Background

Antimicrobial stewardship programs (ASPs) have been shown to reduce inappropriate antimicrobial use and its consequences. However, these programs lack legislative requirements in many places and it can be difficult to determine what human resources are required for these programs and how to create a business case to present to hospital administrators for program funding. The objectives of the current paper were to review legislative requirements and outline human resource requirements for ASPs, and to create a base business case for ASPs.

Methods

A working group of antimicrobial stewardship experts from across Canada met to discuss the necessary components for creation of a business case for antimicrobial stewardship. A narrative review of the literature of the regulatory requirements and human resource recommendations for ASPs was conducted. Informed by the review and using a consensus decision-making process, the expert working group developed human resource recommendations based on a 1000 bed acute care health care facility in Canada. A spreadsheet based business case model for ASPs was also created.

Results

Legislative and /or regulatory requirements for ASPs were found in 2 countries and one state jurisdiction. The literature review and consensus development process recommended the following minimum human resources complement: 1 physician, 3 pharmacists, 0.5 program administrative and coordination support, and 0.4 data analyst support as full time equivalents (FTEs) per 1000 acute care beds. Necessary components for the business case model, including the human resource requirements, were determined to create a spreadsheet based model.

Conclusions

There is evidence to support the negative outcomes of inappropriate antimicrobial use as well as the benefits of ASPs. Legislative and /or regulatory requirements for ASPs are not common. The available evidence for human resource recommendations for ASPs using a narrative review process was examined and a base business case modelling scenario was created. As regulatory requirements for ASPs increase, it will be necessary to create accurate business cases for ASPs in order to obtain the necessary funding to render these programs successful.

Congruity and Divergence in Perceptions of Adolescent Romantic Experience Between Chinese Parents and Adolescents

This qualitative research article explored the convergences and divergences of perceptions of adolescent romantic experience between a group of adolescents and parents in China. One-to-one, in-depth interviews were conducted with 38 adolescents (aged 15-18 years; 26 girls, 12 boys) and 27 parents (aged 40-52 years; 16 mothers, 11 fathers) from the urban areas of a northern Chinese city. Data analysis was conducted using thematic analysis and interpreted using a socio-ecological approach. Four major themes were identified: opportunities and risks, acceptable versus unacceptable sexual intimacy, generational difference, and girls’ vulnerability and “self-respect.” In these themes, congruity and divergence of perceptions were found between the groups of adolescents and parents. These perceptions were largely influenced by traditional cultural beliefs of education, sexuality, gender, and family as well as the current socio-cultural context of modernization and globalization in China. The findings provide implications regarding how to support both adolescents and parents in managing adolescent romantic experience for adolescent health-promoting romantic and sexual behaviors.

Feeding dicyandiamide (DCD) to cattle: An effective method to reduce N2O emissions from urine patches in a heavy-textured soil under temperate climatic conditions

Nitrate (NO₃^-) leaching and nitrous oxide (N₂O) emission from urine patches in grazed pastures are key sources of water and air pollution, respectively. Broadcast spraying of the nitrification inhibitor dicyandiamide (DCD) has been shown to reduce these losses, but it is expensive. As an alternative, it had been demonstrated that feeding DCD to cattle (after manual mixing with supplementary feeds) was a practical, effective and cheaper method to deliver high DCD rates within urine patches. This two-year study carried out on simulated urine patches in three application seasons (spring, summer, autumn) explored the efficacy of DCD feeding to cattle to reduce N losses from grazed pasture soil in a heavy-textured soil under temperate climatic conditions. In each application season, DCD fed to cows, then excreted with urine and applied at a rate of 30kgDCDha^-1 (treatment U+DCD³⁰-f) was as effective as powdered DCD mixed with normal urine and applied at the same rate (treatment U+DCD³⁰) at reducing cumulative N₂O-N emissions and the N₂O-N emission factor (EF3, expressed as % of N applied). Increasing DCD loading within urine patches from 10 to 30kgDCDha^-1 improved efficacy by significantly reducing the EF3 from 34% to 64%, which highlights that under local conditions, 10kgDCDha^-1 (the recommended rate for commercial use in New Zealand) was not the optimum DCD rate to curb N₂O emissions. The modelling of EF3 in this study also suggests that N mitigation should be given more attention when soil moisture is going to be high, which can be predicted with short-term weather forecasting. DCD feeding, for instance in autumn when cows are not lactating and the risk of N losses is high, could then be reduced by focusing mainly on those forecasted wet periods.

Sensitivity, specificity and predictive probability values of serum agglutination test titres for the diagnosis of Salmonella Dublin culture-positive bovine abortion and stillbirth

The objective of this study was to determine the diagnostic value of maternal serology for the diagnosis of Salmonella Dublin bovine abortion and stillbirth. A retrospective, unmatched, case-control study was carried out using twenty year's data (1989-2009) from bovine foetal submissions to an Irish government veterinary laboratory. Cases (n = 214) were defined as submissions with a S. Dublin culture-positive foetus from a S. Dublin unvaccinated dam where results of maternal S. Dublin serology were available. Controls (n = 415) were defined as submissions where an alternative diagnosis other than S. Dublin was made in a foetus from an S. Dublin unvaccinated dam where the results of maternal S. Dublin serology were available. A logistic regression model was fitted to the data: the dichotomous dependent variable was the S. Dublin foetal culture result, and the independent variables were the maternal serum agglutination test (SAT) titre results. Salmonella serology correctly classified 87% of S. Dublin culture-positive foetuses at a predicted probability threshold of 0.44 (cut-off at which sensitivity and specificity are at a maximum, J = 0.67). The sensitivity of the SAT at the same threshold was 73.8% (95% CI: 67.4%-79.5%), and the specificity was 93.2% (95% CI: 90.3%-95.4%). The positive and negative predictive values were 84.9% (95% CI: 79.3%-88.6%) and 87.3% (95% CI: 83.5%-91.3%), respectively. This study illustrates that the use of predicted probability values, rather than the traditional arbitrary breakpoints of negative, inconclusive and positive, increases the diagnostic value of the maternal SAT. Veterinary laboratory diagnosticians and veterinary practitioners can recover from the test results, information previously categorized, particularly from those results declared to be inconclusive.
