Community-associated methicillin-resistant Staphylococcus aureus infections in Aboriginal children attending hospital emergency departments in a regional area of New South Wales, Australia: a seven-year descriptive study
Objective: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) can cause bacterial skin infections that are common problems for Aboriginal children in New South Wales (NSW). MRSA is not notifiable in NSW and surveillance data describing incidence and prevalence are not routinely collected. The study aims to describe the epidemiology of CA-MRSA in Aboriginal children in the Hunter New England Local Health District (HNELHD).
Methods: We linked data from Pathology North Laboratory Management System (AUSLAB) and the HNELHD patient administration system from 33 hospital emergency departments. Data from 2008-2014 for CA-MRSA isolates were extracted. Demographic characteristics included age, gender, Aboriginality, rurality and seasonality.
Results: Of the 1222 individuals in this study, 408 (33.4%) were Aboriginal people. Aboriginal people were younger with 45.8% aged less than 10 years compared to 25.9% of non-Aboriginal people. Most isolates came from Aboriginal people who attended the regional Tamworth Hospital (193/511 isolates from 149 people). A larger proportion of Aboriginal people, compared to non-Aboriginal people, resided in outer regional (64.9% vs 37.2%) or remote/very remote areas (2.5% vs 0.5%). Most infections occurred in summer and early autumn. For Aboriginal patients, there was a downward trend through autumn, continuing through winter and spring.
Discussion: Aboriginal people at HNELHD emergency departments appear to represent a greater proportion of people with skin infections with CA-MRSA than non-Aboriginal people. CA-MRSA is not notifiable in NSW; however, pathology and hospital data are available and can provide valuable indicative data to health districts for planning and policy development
Describing meningococcal disease: understanding, perceptions and feelings of people in a regional area of NSW, Australia
Objectives: To explore understanding, perceptions and feelings about meningococcal disease in members of higher risk groups. To explore what people say are the most important health messages and communication preferences about invasive meningococcal disease (IMD).
Methods: Three focus groups and two semistructured interviews were conducted with people at higher risk of IMD in Hunter New England Local Health District in New South Wales.
Results: Participants generally had a low understanding of IMD, but described intense feelings about the disease and empathy for those who had experienced the disease. Fear of stigma and the impact of stigma were identified. Participants identified reasons for delaying presentation for care as perceptions of invincibility (particularly among young people), the cost of care (for all groups), and racism (particularly for Aboriginal people). These issues were both potential and experienced barriers for participants accessing help when acutely unwell. Factors for effective communication to improve understanding of IMD included the communication being acceptable, accessible and appropriate.
Conclusions: IMD is a serious but uncommon disease that has a range of impacts on people, families and communities. Higher risk groups may benefit from receiving more appropriate and accessible information about early signs and symptoms of IMD. Communication and understanding about the disease could be improved by working with new technologies and partnering with key people in high-risk groups. Use of text messages and social networking for urgent communication could be considered and trialled in public health practice. It is also important to recognise the potential direct or indirect experience of racism and stigma for patients with IMD and their families. Management of IMD could be strengthened by connecting people and families with support groups or services to reduce the impact of the disease
Evaluation of the Australian first few X household transmission project for COVID-19
Background: The Australian First Few X (FFX) Household Transmission Project for COVID-19 was the first prospective, multi-jurisdictional study of its kind in Australia. The project was undertaken as a partnership between federal and state health departments and the Australian Partnership for Preparedness Research on Infectious Disease Emergencies (APPRISE) and was active from April to October 2020.
Methods: We aimed to identify and explore the challenges and strengths of the Australian FFX Project to inform future FFX study development and integration into pandemic preparedness plans. We asked key stakeholders and partners involved with implementation to identify and rank factors relating to the strengths and challenges of project implementation in two rounds of modified Delphi surveys. Key representatives from jurisdictional health departments were then interviewed to contextualise findings within public health processes and information needs to develop a final set of recommendations for FFX study development in Australia.
Results: Four clear recommendations emerged from the evaluation. Future preparedness planning should aim to formalise and embed partnerships between health departments and researchers to help better integrate project data collection into core public health surveillance activities. The development of functional, adaptable protocols with pre-established ethics and governance approvals and investment in national data infrastructure were additional priority areas noted by evaluation participants.
Conclusion: The evaluation provided a great opportunity to consolidate lessons learnt from the Australian FFX Household Transmission Project. The developed recommendations should be incorporated into future pandemic preparedness plans in Australia to enable effective implementation and increase local utility and value of the FFX platform within emergency public health response
Ezidi voices: The communication of COVID-19 information amongst a refugee community in rural Australia- a qualitative study
Background: There is growing evidence that government health information related to COVID-19 has failed to adequately reach culturally and linguistically diverse (CALD) populations in Australia. Refugees are a unique sub-set of the CALD communities and are subject to numerous barriers preventing adequate health care, both pre- and post-migration. The barriers are accentuated during emergencies, such as a pandemic, as a result of an intersection of various social and economic inequalities. The recently resettled Ezidi refugee community in a regional area of Australia is an example of a community sitting at the intersection of various inequities and thus at greater risk from COVID-19. The purpose of this study is to describe the experiences of the Ezidi in a regional area with COVID-19 information and how this has been communicated to and shared within this group; what barriers the community may experience in accessing COVID-19 information; and how the government-led COVID-19 information communication could be improved.
Methods: This qualitative study was designed to explore the perceptions and views of the Ezidi and service providers regarding COVID-19 messaging. Multicultural and Refugee Health staff facilitated interviews with four local service providers and ten Ezidi community members, including seven influential leaders. Thematic analysis was employed across individual, pair and group data analysis. Similar categories were grouped into themes.
Results: The main findings of the study are: the refugee experience influences the communication of COVID-19 messages; cultural, social and gender norms influence responses to COVID-19; trusted individuals and service providers are key in communities’ uptake of COVID-19 messages; currently available governmental COVID-19 information resources and sharing strategies were found unhelpful and inappropriate; COVID-19 communiqués and message delivery for this regional minority refugee community can be improved.
Conclusion: The recently resettled Ezidi community, and likely other similar communities, would benefit from tailored engagement by government organisations, as well as settlement services to improve the communication of COVID-19 health information and reduce related inequities
Factors contributing to the sharing of COVID-19 health information amongst refugee communities in a regional area of Australia: a qualitative study
Background: The COVID-19 pandemic has had a disproportionate impact on culturally and linguistically diverse (CALD) groups worldwide. Newly emerging CALD populations formed by recently arrived refugees are predisposed to even greater health disadvantages due to complexities of the refugee experience. The aim of this study was to explore how culture, refugee experiences and existing relationships shaped what COVID-19 messages were listened to and shared during the early-mid phases of the pandemic. The work focused on three newly emerging refugee groups in the Hunter New England region, Australia: Afghan, Congolese and Syrian communities.
Methods: Qualitative, semi-structured interviews were conducted to explore the experiences and stories of 15 adult community members, nine influential members and six service providers. All community members arrived in Australia on or after January 2014. Interpreter-assisted interviews were conducted with small groups or individuals, audio-recorded and transcribed verbatim in English. Three levels of thematic data analysis were employed to uncover the important issues and experiences of the participants.
Results: Three key themes and several subthemes were identified. The themes were: 1) Experience as a refugee uniquely influences COVID-19 message communication; 2) Refugee groups use diverse practices when accessing and sharing COVID-19 messages; and 3) Official government messages could be improved by listening and tailoring to community needs.
Conclusions: Effective health messaging relies on reaching communities in a culturally acceptable and meaningful way. Official COVID-19 messages can be tailored to engage newly emerging communities by improving the quality of the content, delivery and format whilst working collaboratively with communities and trusted service providers. Further mutual research is needed to understand emerging communities’ viewpoints. The use of culturally informed approaches is recommended
The ongoing value of first few X studies for COVID-19 in the Western Pacific Region
First few ‘X’ (FFX) studies for COVID-19 involve data collection from confirmed cases and their close contacts. They remain relevant especially as many remain susceptible to infection, and as they can provide detailed insight into vaccine effectiveness and the epidemiology of variants of concern, helping to inform a proportionate health response
A Phase I Trial of Aminolevulinic Acid-Photodynamic Therapy for Treatment of Oral Leukoplakia
Background Photodynamic therapy with aminolevulinic acid (ALA PDT) for oral leukoplakia has shown promising effects in regression of oral leukoplakia. Although ALA has been extensively studied and is an ideal photosensitizer, the optimal light dose for treatment of oral leukoplakia has not been determined. We conducted a phase I study to determine MTD and DLT of PDT in patients treated with ALA for leukoplakia. Methods Patients with histologically confirmed oral leukoplakia received a single treatment of ALA PDT in cohorts with escalating doses of light (585 nm). Clinical, histologic, and biologic markers were assessed. Results Analysis of 11 participants is reported. No significant toxicity from ALA PDT was observed in patients who received ALA with a light dose of up to 4 J/cm2. One participant experienced transient grade 3 transaminase elevation due to ALA. One participant had a partial clinical response 3 months after treatment. Biologic mucosal risk markers showed no significant associations. Determination of MTD could not be accomplished within a feasible timeframe for completion of the study. Conclusions ALA PDT could be safely administered with a light dose up to 4 J/cm2 and demonstrated activity. Larger studies are needed to fully elucidate the MTD and efficacy of ALA-PDT
Tuberculosis care designed with barramarrany (family): Participatory action research that prioritised partnership, healthy housing and nutrition
Issue addressed
Ongoing tuberculosis (TB) transmission in Aboriginal communities in Australia is unfair and unacceptable. Redressing the inequity in TB affecting Aboriginal peoples is a priority in Australia’s Strategic Plan for Tuberculosis Control. Improving TB care needs not to just identify barriers but do something about them. Privileging the voices of Aboriginal people affected by TB is essential to identify effective and enabling strategies.
Methods
A barramarrany (Aboriginal family) affected by recurring TB partnered with TB and Environmental Health teams using a participatory action research (PAR) methodology to improve housing health hardware and nutrition alongside biomedical TB prevention and care. A combination of the Ottawa Charter for Health Promotion; the International ‘End TB’ Strategy; and Aboriginal barramarrany leadership, worldviews and traditional values guided actions to reduce TB transmission.
Results
Together the partners improved housing hardware and access to nutritious food, so the barramarrany could create a setting for good health and wellbeing. These actions supported the barramarrany to regain the physical, social and emotional wellbeing to deal with day-to-day challenges and stresses. The barramarrany were able to better sustain supportive relationships; grow, prepare and eat healthy food; and participate in healthcare activities. The barramarrany could better engage with medical approaches for TB and four barramarrany members completed TB treatment. The PAR action-project enabled and supported early TB diagnosis, treatment and prevention.
Conclusion
Amplifying the voices of Aboriginal people and shared ownership of TB diagnosis, treatment and prevention by the barramarrany, was underpinned with principles of self-determination, capacity building and social justice. This PAR action-project provides further evidence that improving housing and nutrition can assist in Ending TB while improving wellbeing.
So what?
Our action-research project undertaken within a PAR framework demonstrates the implementation of End TB Strategies by utilising the Ottawa Charter’s five actions to promote health, by understanding and centralising the social determinants of health
The Recent Star Formation in NGC 6822: an Ultraviolet Study
We characterize the star formation in the low-metallicity galaxy NGC 6822
over the past few hundred million years, using GALEX far-UV (FUV, 1344-1786 A)
and near-UV (NUV, 1771-2831 A) imaging, and ground-based Ha imaging. From GALEX
FUV image, we define 77 star-forming (SF) regions with area >860 pc^2, and
surface brightness <=26.8 mag(AB)arcsec^-2, within 0.2deg (1.7kpc) of the
center of the galaxy. We estimate the extinction by interstellar dust in each
SF region from resolved photometry of the hot stars it contains: E(B-V) ranges
from the minimum foreground value of 0.22mag up to 0.66+-0.21mag. The
integrated FUV and NUV photometry, compared with stellar population models,
yields ages of the SF complexes up to a few hundred Myr, and masses from 2x10^2
Msun to 1.5x10^6 Msun. The derived ages and masses strongly depend on the
assumed type of interstellar selective extinction, which we find to vary across
the galaxy. The total mass of the FUV-defined SF regions translates into an
average star formation rate (SFR) of 1.4x10^-2 Msun/yr over the past 100 Myr,
and SFR=1.0x10^-2 Msun/yr in the most recent 10 Myr. The latter is in agreement
with the value that we derive from the Ha luminosity, SFR=0.008 Msun/yr. The
SFR in the most recent epoch becomes higher if we add the SFR=0.02 Msun/yr
inferred from far-IR measurements, which trace star formation still embedded in
dust (age <= a few Myr).Comment: Accepted for publication in ApJ, 21 pages, 6 figures, 3 table
Surveillance system enhancements for Q fever in NSW, 2005-2015.
Q fever remains an important notifiable, zoonotic disease in Australia. Previous epidemiological reviews have noted increased importance of non-abattoir contact with livestock and native/feral animals. Changes to surveillance in New South Wales (NSW) have provided enhanced surveillance data with which to examine exposure pathways. Descriptive analysis of NSW Q fever notification data for the period 2005-2015, with detailed analysis of exposures for the period 2011-2015 (after introduction of improvements to surveillance). Between 2005 and 2015, 1,653 confirmed cases of Q fever were notified in NSW residents who acquired the disease in this state. For the period 2011-2015, a high-risk occupation was reported in 345/660 (52.3%) of notifications with a known occupation. Of 641 cases with a known animal exposure, 345 (53.8%) had direct contact with livestock, while 62 (9.7%) had indirect contact with livestock (e.g. proximity to livestock, livestock holding areas or trucks). Direct or indirect contact with native/feral animals was reported in 111/641 (17.3%) cases. Mowing and close proximity to kangaroos/wallabies were commonly reported indirect exposure pathways, particularly in urban areas. Enhancements to the state based surveillance database in NSW introduced in 2010 have resulted in improved collection of surveillance data for Q fever. Further refinement of Q fever surveillance can be achieved through continuing to improve data quality, standardising data collection and better elucidating exposure pathways of cases
