'Profound personal and professional impacts': A qualitative study of clinician experiences of a mental health disaster response to Australia's black summer bushfires.

Australian Journal of Rural Health

To explore the experiences of clinician and management stakeholders involved in a rural/metropolitan collaborative mental health disaster response to the 2019-2020 Black Summer bushfires in the Snowy Valleys region of southern New South Wales (NSW), Australia.

An interpretive qualitative study design using semi-structured individual interviews, with transcripts analysed using Reflexive Thematic Analysis.

Thematic findings on participant experiences are presented under three organising constructs of before (stepping up and jumping right in), during (finding a rhythm of working together), and after (profound personal and professional impacts) the mental health disaster response.

Participant experiences had shared and distinct components before, during and after the mental health disaster response, culminating in profound personal and professional impacts. Findings highlight positive aspects and challenges for clinicians participating in a rural/metropolitan collaborative mental health disaster response. The findings of this study contribute new knowledge about experiences of mental health clinicians participating in a disaster response after bushfires, from dual perspectives of members of a bushfire-affected community and those responding from outside a bushfire-affected community, which may inform ongoing planning of responses to disaster in Australia.

Pretest-post-test evaluation with lay midwives in remote Guatemala after educational activities about COVID-19.

Rural and Remote Health

Guatemalan lay midwives are well-respected community leaders in a country that lacks the institutional capacity to meet healthcare needs related to pregnancy, newborns, and COVID-19. Thus, Guatemalan lay midwives, who attend the majority of births in their country and who attend most births at home, are in an optimal position to offer frontline support to pregnant women and newborns regarding the global pandemic. The primary objective of this program of study was to dispel myths about COVID-19 and to provide culturally relevant educational activities to low-literacy Guatemalan lay midwives about issues related to the virus, such as signs and symptoms, risks to the mother and fetus, which patients are most vulnerable, appropriate responses, benefits and side-effects of the vaccine, timing of the vaccine, how the virus interacts with breastfeeding, and breastfeeding recommendations.

In a partnership among the Guatemalan Ministry of Health, expert faculty at the University of Utah College of Nursing, and Madre y Niño, a non-profit organization from the US, evidence-based educational activities about COVID-19 were offered orally in the native language of participants. Two hundred and ten lay midwives attended educational sessions at 11 locations throughout the remote Peten department. Educational activities included repetition, storytelling, and role plays. A pretest-post-test evaluation of 10 questions with 24 correct answers was used to determine if the educational activities changed lay midwife knowledge about COVID-19. Participants were given essential birth supplies and laminated COVID Reminder Cards, which were designed to increase visual literacy, to encourage knowledge retention after the educational sessions.

Participants showed a significant increase in knowledge scores (possible 0-24) from prescores 7.09 (standard deviation (SD)=3.06) to 15.20 (SD=4.61), Student's t-test p<0.001. In addition, a significantly higher proportion of participants mistakenly thought COVID-19 passed through breast milk on the pretest (70.1%) compared to post-test (8.4%) (McNemar test, p<0.001). Regarding breastfeeding, 12.6% of participants knew on the pretest that women with COVID-19 who breastfeed should wear a mask and wash their hands compared to 74.3% of participants who knew these recommendations on the post-test (Wilcoxon signed-rank test, p<0.001). Finally, 2% of participants knew on the pretest that pregnant women with COVID-19 should take a low-dose aspirin compared to 67% of participants on the post-test (χ&sup2; (1)=194.7, p<0.001).

These essential primary care providers misunderstood many critical issues related to COVID-19, pregnancy, and newborns. Culturally relevant educational activities provided orally in the native language of participants dispelled myths about the virus and significantly improved lay midwife knowledge. Providing evidence-based educational activities in a culturally relevant format is critical to protecting remote, vulnerable populations, such as pregnant Guatemalan women and newborns, during a global pandemic.

Discharge against medical advice in rural and remote emergency departments: views of healthcare providers.

Rural and Remote Health

The aim of the study was to explore, in one remote hospital, emergency department healthcare providers' experience and perceptions of the factors surrounding a patient's decision to discharge against medical advice (DAMA). The secondary objective was to gain insight into staff experiences of the current protocols for managing DAMA cases and explore their recommendations for reducing DAMA incidence.

This was a cross-sectional study involving a survey and semi-structured interviews exploring healthcare providers' (n=19) perceptions of factors perceived to be influencing DAMA, current practice for managing DAMA and recommendations for practice improvements. Health professionals (doctors, nurses, Aboriginal Health Workers) all worked in the emergency department of a remote community hospital, Queensland, Australia. Responses relating to influencing factors for DAMA were provided on a three-point rating scale from 'no influence/little influence' to 'very strong influence'. DAMA management protocol responses were a three-point rating scale from 'rarely/never' to 'always'. Semi-structured interviews were conducted after the survey and explored participants' perceptions in greater detail and current DAMA management protocol.

Feedback from the total of 19 participants across the professions presented four prominent yet interconnected themes: patient, culture, health service and health provider, and health literacy and education-related factors. Factors that were perceived to have a strong influence on DAMA events included alcohol and drug abuse (100%), a lack of culturally sensitive healthcare services (94.7%), and family commitments or obligations (89.5%). Healthcare provider recommendations for preventing DAMA presented themes of right communication, culturally safe care (right place, right time) and the right staff to support DAMA prevention. The healthcare providers described the pivotal role the Indigenous Liaison Officer (ILO) plays and the importance of this position being filled.

DAMA is a multifaceted issue, influenced by both personal and hospital system-related factors. Participants agreed that the presence of ILO and/or Aboriginal Health Workers in the emergency department may reduce DAMA occurrences for Indigenous Australians who are disproportionately represented in DAMA rates, particularly in rural and remote regions of Australia.

'I am more than my diagnosis': Amplifying the voice of consumers in the design and delivery of mental health services.

Australian Journal of Rural Health

In line with the Australian Government's Vision 2030, this research foregrounds consumer experiences of recovery to inform the (co)design and delivery of mental health services for people living with complex needs and/or a severe and persistent mental health condition.

A tripartite framework integrating recovery oriented, trauma-informed and collective impact approaches for a qualitative, arts-based (photovoice) study.

In areas of the mental health service system that had not yet applied a personalised understanding of recovery or embraced trauma-informed practice there were a range of issues and gaps in service delivery relating to authentic relationships, belonging and connection, service cultures, trauma-informed care, and workforce investment.

Clinical and non-clinical services need to ensure consistent person-centred and trauma-informed practice is implemented throughout the mental health service system to meet the needs of the consumer. An eight-point checklist serves as the basis for services to reflect on how they are working with consumers and to support the review of systems and clinical governance frameworks.

Clinical presentation and management of enterovirus and parechovirus infection in children: A single-centre study in regional Australia.

Australian Journal of Rural Health

This study aims to analyse the clinical presentation caused by enterovirus (EV) and/or human parechovirus (HPeV) infection in children, as well as the management of such cases admitted to a regional hospital in Australia.

Data collected included demographic data, signs and symptoms present, specimens of EV/HPeV isolation, co-occurring pathogens, peak C-reactive protein (CRP), antibiotic therapy, discharge diagnosis and follow-up after discharge.

Overall, 27 patients fulfilled the inclusion criteria; 81.5% of the patients were ≤3 months of age with a median of 2 months (interquartile range 1-3); 74.1% were males. The most common clinical features were a fever ≥38°C and irritability/lethargy/high-pitched cry. 29.6% of the patients had co-occurring pathogens detected, and a CRP ≤10 mg/L was observed in 77.8% of cases. All but two children were treated with antibiotics while awaiting polymerase chain reaction results. The most common discharge diagnosis was meningitis. In all, 74.1% of the children attended follow-up appointments.

EV and HPeV should be considered as a possible aetiology of fever and irritability/lethargy/high-pitched cry in children under 3 months.

Prediction of Time to Hemodynamic Stabilization of Unstable Injured Patient Encounters Using Electronic Medical Record Data.

Shock

This study sought to predict time to patient hemodynamic stabilization during trauma resuscitations of hypotensive patient encounters using electronic medical records (EMR) data.

This observational cohort study leveraged EMR data from a nine-hospital academic system composed of Level I, Level II and non-trauma centers. Injured, hemodynamically unstable (initial systolic blood pressure < 90 mmHg) emergency encounters from 2015-2020 were identified. Stabilization was defined as documented subsequent systolic blood pressure > 90 mmHg. We predicted time to stabilization testing random forests, gradient boosting and ensembles using patient, injury, treatment, EPIC Trauma Narrator and hospital features from the first four hours of care.

Of 177,127 encounters, 1347 (0.8%) arrived hemodynamically unstable; 168 (12.5%) presented to Level I trauma centers, 853 (63.3%) to Level II, and 326 (24.2%) to non-trauma centers. Of those, 747 (55.5%) were stabilized with a median of 50 minutes (IQR 21-101 min). Stabilization was documented in 94.6% of unstable patient encounters at Level I, 57.6% at Level II and 29.8% at non-trauma centers (p < 0.001). Time to stabilization was predicted with a C-index of 0.80. The most predictive features were EPIC Trauma Narrator measures; documented patient arrival, provider exam, and disposition decision. In-hospital mortality was highest at Level I, 3.0% vs. 1.2% at Level II, and 0.3% at non-trauma centers (p < 0.001). Importantly, non-trauma centers had the highest re-triage rate to another acute care hospital (12.0%) compared to Level II centers (4.0%, p < 0.001).

Time to stabilization of unstable injured patients can be predicted with EMR data.

Metabolic and Bioenergetic Alterations are Associated with Infection Susceptibility in Survivors of Severe Trauma: An Exploratory Study.

Shock

Trauma and blood loss are frequently associated with organ failure, immune dysfunction, and a high risk of secondary bacterial lung infections. We aim to test if plasma metabolomic flux and monocyte bioenergetics are altered in association with trauma and related secondary infections.

Plasma samples were collected from trauma patients at three time points: days 0, 3, and 7 post-admission. Metabolites (140) were measured in plasma from trauma survivors (n = 24) and healthy control individuals (HC, n = 10). Further analysis within the trauma cohort included subsets of trauma/infection-negative (TIneg, n = 12) and trauma/infection-positive patients (TIpos, n = 12). The bioenergetic profile in monocytes was determined using mitochondrial and glycolytic stress tests.

In the trauma cohort, significant alterations were observed in 29 metabolites directly affecting 11 major metabolic pathways, while 34 metabolite alterations affected 8 pathways in TIpos, versus TIneg patients. The most altered metabolic pathways included protein synthesis, the urea cycle/arginine metabolism, phenylalanine, tyrosine, tryptophan biosynthesis, and carnitine compound family. In monocytes from trauma patients, reduced mitochondrial indices and loss of glycolytic plasticity were consistent with an altered profile of plasma metabolites in the TCA cycle and glycolysis.

Our study highlights that the metabolic profile is significantly and persistently affected by trauma and related infections. Among trauma survivors, metabolic alterations in plasma were associated with reduced monocyte bioenergetics. These exploratory findings establish a groundwork for future clinical studies aimed at enhancing our understanding of the interplay between metabolic/bioenergetic alterations associated with trauma and secondary bacterial infections.

Renin and angiotensin (1-7) offer predictive value in pediatric sepsis: findings from prospective observational cohorts.

Shock

Pediatric sepsis is a common and complex syndrome characterized by a dysregulated immune response to infection. Aberrations in the renin-angiotensin system (RAS) are factors in several infections of adults. However, the precise impact of RAS dysregulation in pediatric sepsis remains unclear.

Serum samples were collected from a derivation cohort (58 patients with sepsis, 14 critically ill control subjects, and 37 healthy controls) and validation cohort (50 patients with sepsis, 37 critically ill control subjects, and 46 healthy controls). Serum RAS levels on day of PICU admission were determined and compared with survival status and organ dysfunction.

In the derivation cohort, the serum renin concentration was significantly higher in patients with sepsis (3678 ± 4746) than that in healthy controls(635.6 ± 199.8) (p < 0.0001). Meanwhile, the serum angiotensin (1-7) was significantly lower in patients with sepsis (89.7 ± 59.7) compared to that in healthy controls(131.4 ± 66.4) (p < 0.01). These trends were confirmed in a validation cohort. Non-survivors had higher levels of renin (8207 ± 7903) compared to survivors (2433 ± 3193) (p = 0.0001) and lower levels of angiotensin (1-7) (60.9 ± 51.1) compared to survivors (104.0 ± 85.1) (p < 0.05). A combination of renin, angiotensin (1-7) and procalcitonin achieved a model for diagnosis with an area under the receiver operating curve (AUROC) of 0.87 (95% CI: 0.81-0.92).

Circulating renin and angiotensin (1-7) have predictive value in pediatric sepsis.

Heterogenous expansion of polymorphonuclear myeloid-derived suppressor cells distinguishes high-risk sepsis immunophenotypes in Uganda.

Shock

Understanding of immune cell phenotypes associated with inflammatory and immunosuppressive host responses in sepsis is imprecise, particularly in low- and middle-income countries (LMICs), where the global sepsis burden is concentrated. In these settings, elucidation of immunophenotypes with prognostic importance is necessary to determine the relevance of emerging therapeutics and refine mechanistic investigations of sepsis immunopathology.

In a prospective cohort of adults hospitalized with suspected sepsis in Uganda (N = 43; median age 46 years [IQR 36-59], 24 [55.8%] living with HIV, 16 [37.2%] deceased at 60 days), we combined high-dimensional flow cytometry with unsupervised machine learning and manual gating to define peripheral immunophenotypes associated with increased risk of 60-day mortality.

Patients who died showed heterogenous expansion of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), with increased and decreased abundance of CD16negPD-L1dim and CD16brightPD-L1bright subsets, respectively, significantly associated with mortality. While differences between CD16negPD-L1dim cell abundance and mortality risk appeared consistent throughout the course of illness, those for the CD16brightPD-L1bright subset were more pronounced early after illness onset. Independent of HIV co-infection, depletion of CD4+ T cells, dendritic cells, and CD56-CD16bright NK cells were significantly associated with mortality risk, as was expansion of immature, CD56+CD16-CD11c+ NK cells. Abundance of T cells expressing inhibitory checkpoint proteins (PD-1, CTLA-4, LAG3) was similar between patients who died versus those who survived.

This is the first study to define high risk immunophenotypes among adults with sepsis in sub-Saharan Africa, an immunologically distinct region where biologically informed treatment strategies are needed. More broadly, our findings highlight the clinical importance and complexity of MDSC expansion during sepsis and support emerging data that suggest a host-protective role for PD-L1 myeloid checkpoints in acute critical illness.

The link between pesticide exposure and suicide in agricultural workers: a systematic review.

Rural and Remote Health

The aim of this study was to conduct a systematic literature review to find the association between pesticide exposure and the incidence of suicide in agricultural workers, focusing on analyzing the profile of agricultural workers, the countries with the highest number of publications and, especially, the link between occupational exposure to pesticides, the degradation of mental health and suicide among agricultural workers.

A systematic literature review was conducted following the PRISMA protocol using Scopus, Web of Science, and PubMed databases, where 33 articles were screened to compose the final portfolio.

There is a strong link between pesticide exposure and suicide in agricultural workers. Smoking, alcohol consumption, exposure time, and marital status influence the decision to die by suicide. Brazil and the US lead the ranking in publications, demonstrating that it is not a problem only for developing countries. Organophosphates are the main pesticides used, and they degrade an enzyme crucial for the nervous system, which can result in mental disorders and consequent suicide in agricultural workers.

There is a need for stricter norms for the commercialization and use of pesticides. There is also a need for providing training to agricultural workers on the application and storage of pesticides, and to communicate about the compounds and the consequences of pesticides to mental health.

Global prevalence of musculoskeletal pain in rural and urban populations. A systematic review with meta-analysis. Musculoskeletal pain in rural and urban populations.

Australian Journal of Rural Health

To systematically compare the global prevalence of musculoskeletal pain and care-seeking in rural and urban populations.

A systematic review with meta-analysis of observational studies reporting a direct comparison of rural and urban populations was conducted worldwide and included back, knee, hip, shoulder, neck pain and a broad diagnosis of 'musculoskeletal pain'. A search strategy combining terms related to 'prevalence', 'musculoskeletal pain' and 'rural' was used on the following databases: MEDLINE, Embase, CINAHL, Scopus, and rural and remote health from their inception to 1 June 2022. Random-effects meta-analysis was used to pool the data. Results were presented as odds ratios (OR) along with 95% confidence intervals (95% CI).

A total of 42 studies from 24 countries were included with a total population of 489 439 participants. The quality scores for the included studies, using the modified Newcastle Ottawa Scale tool, showed an average score of 0.78/1, which represents an overall good quality. The pooled analysis showed statistically greater odds of hip (OR = 1.62, 95% CI = 1.23-2.15), shoulder (OR = 1.42, 95% CI = 1.06-1.90) and overall musculoskeletal pain (OR = 1.26, 95% CI = 1.08-1.47) in rural populations compared to urban populations. Although the odds of seeking treatment were higher in rural populations this relationship was not statistically significant (OR = 0.76, 95% CI = 0.55-1.03).

Very low-certainty evidence suggests that musculoskeletal, hip and shoulder pain are more prevalent in rural than urban areas, although neck, back and knee pain, along with care-seeking, showed no significant difference between these populations. Strategies aimed to reduce the burden of musculoskeletal pain should consider the specific needs and limited access to quality evidence-based care for musculoskeletal pain of rural populations.
