Inference of tobacco and alcohol consumption habits from DNA methylation analysis of blood

DNA methylation has become a biomarker of great interest in the forensic and clinical fields. In criminal investigations, the study of this epigenetic marker has allowed the development of DNA intelligence tools providing information that can be useful for investigators, such as age prediction. Following a similar trend, when the origin of a sample in a criminal scenario is unknown, the inference of an individual's lifestyle such as tobacco use and alcohol consumption could provide relevant information to help in the identification of DNA donors at the crime scene. At the same time, in the clinical domain, prediction of these trends of consumption could allow the identification of people at risk or better identification of the causes of different pathologies. In the present study, DNA methylation data from the UK AIRWAVE study was used to build two binomial logistic models for the inference of smoking and drinking status. A total of 348 individuals (116 non-smokers, 116 former smokers and 116 smokers) plus a total of 237 individuals (79 non-drinkers, 79 moderate drinkers and 79 drinkers) were used for development of tobacco and alcohol consumption prediction models, respectively. The tobacco prediction model was composed of two CpGs (cg05575921 in AHRR and cg01940273) and the alcohol prediction model three CpGs (cg06690548 in SLC7A11, cg0886875 and cg21294714 in MIR4435-2HG), providing correct classifications of 86.49% and 74.26%, respectively. Validation of the models was performed using leave-one-out cross-validation. Additionally, two independent testing sets were also assessed for tobacco and alcohol consumption. Considering that the consumption of these substances could underlie accelerated epigenetic ageing patterns, the effect of these lifestyles on the prediction of age was evaluated. To do that, a quantile regression model based on previous studies was generated, and the potential effect of tobacco and alcohol consumption with the epigenetic age was assessed. The Wilcoxon test was used to evaluate the residuals generated by the model and no significant differences were observed between the categories analyzed.

Diagnostic delay of sarcoidosis: an integrated systematic review

BACKGROUND

Sarcoidosis is a chronic inflammatory granulomatous disease of unknown cause. Delays in diagnosis can result in disease progression and poorer outcomes for patients. Our aim was to review the current literature to determine the overall diagnostic delay of sarcoidosis, factors associated with diagnostic delay, and the experiences of people with sarcoidosis of diagnostic delay.

METHODS

Three databases (PubMed/Medline, Scopus, and ProQuest) and grey literature sources were searched. Random effects inverse variance meta-analysis was used to pool mean diagnostic delay in all types of sarcoidosis subgroup analysis. Diagnostic delay was defined as the time from reported onset of symptoms to diagnosis of sarcoidosis.

RESULTS

We identified 374 titles, of which 29 studies were included in the review, with an overall sample of 1531 (694 females, 837 males). The overall mean diagnostic delay in all types of sarcoidosis was 7.93 months (95% CI 1.21 to 14.64 months). Meta-aggregation of factors related to diagnostic delay in the included studies identified three categories: (1) the complex and rare features of sarcoidosis, (2) healthcare factors and (3) patient-centred factors. Meta-aggregation of outcomes reported in case studies revealed that the three most frequent outcomes associated with diagnostic delay were: (1) incorrect diagnosis, (2) incorrect treatment and (3) development of complications/disease progression. There was no significant difference in diagnostic delay between countries with gatekeeper health systems (where consumers are referred from a primary care clinician to specialist care) and countries with non-gatekeeper systems. No qualitative studies examining people's experiences of diagnostic delay were identified.

CONCLUSION

The mean diagnostic delay for sarcoidosis is almost 8 months, which has objective consequences for patient management. On the other hand, there is a paucity of evidence about the experience of diagnostic delay in sarcoidosis and factors related to this. Gaining an understanding of people's experiences while seeking a diagnosis of sarcoidosis is vital to gain insight into factors that may contribute to delays, and subsequently inform strategies, tools and training activities aimed at increasing clinician and public awareness about this rare condition.

Intergroup Contact Improves Medical Student Attitudes and Skill in Transgender Health Care

Purpose

Poorer health outcomes for transgender and gender diverse (TGD) individuals have been associated with lack of health care provider knowledge and personal bias. Training at all levels of medical education has been positioned as one strategy to combat these inequities. This study sought to characterize preclinical medical student attitude, skill, and knowledge pre- and post-teaching with TGD community volunteers.

Methods

This matched pre- and post-test study was conducted from July 2020 to August 2021 capturing two preclinical medical student cohorts exposed to the same teaching intervention. Students completed the Transgender Attitudes and Beliefs Scale (TABS) and the Transgender Development of Clinical Skills Scale (T-DOCSS) at baseline, 1 week, and 1 month after the clinical skills session. Tutors' attitudes to TGD health were measured before facilitating teaching, using the Attitudes Toward Transgender Patients and Beliefs and Knowledge about Treating Transgender Patients scales.

Results

Fifty-nine students completed questionnaires at three time points and were included in this study. Total TABS and T-DOCCS scores increased from preintervention to 1-week follow-up, maintained at 1 month, with significant changes in Interpersonal Comfort and Sex and Gender Beliefs subscales. Scores on the Human Value subscale did not change, remaining consistently high. Postintervention knowledge-question scores were high. Nine of 13 tutors completed surveys, demonstrating overall positive attitudes toward gender diversity and TGD health.

Conclusion

This study demonstrates improvement in preclinical medical student attitudes and self-reported skill toward gender health care sustained at 1 month after small-group teaching with TGD community volunteers.

Adapting an established Ampliseq microhaplotype panel to nanopore sequencing through direct PCR

We have adapted an established Ampliseq microhaplotype panel for nanopore sequencing with the Oxford Nanopore Technologies (ONT) system, as a cost-effective and highly scalable solution for forensic genetics applications. For this purpose, we designed a protocol combining direct PCR amplification from unextracted DNA with ONT library construction and sequencing using the MinION device and workflow. The analysis of reference samples at input amounts of 5-10 ng of DNA demonstrates stable coverage patterns, allele balance, and strand bias, reaching profile completeness and concordance rates of ∼95%. Similar levels were achieved when using direct-PCR from blood, buccal and semen swabs. Dilution series results indicate sensitivity is maintained down to 250 pg of input DNA, and informative profiles are produced down to 62.5 pg. Finally, we demonstrated the forensic utility of the nanopore workflow by analyzing two third degree pedigrees that showed low likelihood ratio values after the analysis of an extended panel of 38 STRs, achieving likelihood ratios 2-3 orders of magnitude higher when testing with the MinION-based haplotype data.

Development of an epigenetic age predictor for costal cartilage with a simultaneous somatic tissue differentiation system

Age prediction from DNA has been a topic of interest in recent years due to the promising results obtained when using epigenetic markers. Since DNA methylation gradually changes across the individual's lifetime, prediction models have been developed accordingly for age estimation. The tissue-dependence for this biomarker usually necessitates the development of tissue-specific age prediction models, in this way, multiple models for age inference have been constructed for the most commonly encountered forensic tissues (blood, oral mucosa, semen). The analysis of skeletal remains has also been attempted and prediction models for bone have now been reported. Recently, the VISAGE Enhanced Tool was developed for the simultaneous DNA methylation analysis of 8 age-correlated loci using targeted high-throughput sequencing. It has been shown that this method is compatible with epigenetic age estimation models for blood, buccal cells, and bone. Since when dealing with decomposed cadavers or postmortem samples, cartilage samples are also an important biological source, an age prediction model for cartilage has been generated in the present study based on methylation data collected using the VISAGE Enhanced Tool. In this way, we have developed a forensic cartilage age prediction model using a training set composed of 109 samples (19-74 age range) based on DNA methylation levels from three CpGs in FHL2, TRIM59 and KLF14, using multivariate quantile regression which provides a mean absolute error (MAE) of ± 4.41 years. An independent testing set composed of 72 samples (19-75 age range) was also analyzed and provided an MAE of ± 4.26 years. In addition, we demonstrate that the 8 VISAGE markers, comprising EDARADD, TRIM59, ELOVL2, MIR29B2CHG, PDE4C, ASPA, FHL2 and KLF14, can be used as tissue prediction markers which provide reliable blood, buccal cells, bone, and cartilage differentiation using a developed multinomial logistic regression model. A training set composed of 392 samples (n = 87 blood, n = 86 buccal cells, n = 110 bone and n = 109 cartilage) was used for building the model (correct classifications: 98.72%, sensitivity: 0.988, specificity: 0.996) and validation was performed using a testing set composed of 192 samples (n = 38 blood, n = 36 buccal cells, n = 46 bone and n = 72 cartilage) showing similar predictive success to the training set (correct classifications: 97.4%, sensitivity: 0.968, specificity: 0.991). By developing both a new cartilage age model and a tissue differentiation model, our study significantly expands the use of the VISAGE Enhanced Tool while increasing the amount of DNA methylation-based information obtained from a single sample and a single forensic laboratory analysis. Both models have been placed in the open-access Snipper forensic classification website.

'A human face and voice': transgender patient-educator and medical student perspectives on gender-diversity teaching

BACKGROUND

Transgender and gender diverse (TGD) people face many obstacles in accessing health care, including discrimination, institutional bias, and clinician knowledge deficits. We developed a clinical skills and education module on gender-affirming care for pre-clinical medical students, in collaboration with a TGD-led civil society organisation. The module consisted of an educational session followed by preceptor-facilitated small group tutorials, led by TGD patient-educators (n = 22) who used their lived experience to explore medical history-taking and broader issues related to TGD healthcare with students (n = 199). This study aimed to explore the views of students and TGD patient-educators on the structure, delivery and impact of the module.

METHODS

Analysis of responses of TGD patient-educators and students to the module (2020 and 2021), in post-intervention surveys using open-ended questions for TGD patient-educators (18 responses from 22 educators) and free text comments as part of a quantitative survey for medical students (89 responses).

RESULTS

Responses from students and patient-educators to the session were highly positive. Students and patient-educators emphasised that the teaching session succeeded through elevating the centrality of shared experience and creating a safe space for learning and teaching. Safety was experienced by patient-educators through the recognition of their own expertise in a medical environment, while students reported a non-judgemental teaching space which allowed them to explore and redress recognised limitations in knowledge and skill. Patient-educators described their motivation to teach as being driven by a sense of responsibility to their community. Preceptor attitudes may function as a barrier to the effectiveness of this teaching, and further attention should be paid to supporting the education of clinical facilitators in TGD health.

CONCLUSION

The experiences of TGD patient-educators and medical students in this study suggest that this model of teaching could serve as a transferable template for TGD health and the inclusion of other historically marginalised groups in medical education.

Male pediatric, adolescent, and young adult reproductive survivorship

As pediatric, adolescent, and young adult cancer survival rates increase, emphasis is placed on reducing late effects, including reproductive complications and potential impact to fertility. Male survivors are at risk of abnormalities in sperm, hormone deficiencies, and sexual dysfunction. This can impact one's progression into puberty and ability to have a biological child and impacts quality of life following treatment. Access to reproductive care is important and requires patient assessment and appropriate referral to reproductive specialists. This review addresses reproductive complications associated with therapy, standard-of-care testing, and therapeutic interventions. The psychologic impact on psychosexual functioning is also addressed.

Vaginal laser therapy for GSM/VVA: where we stand now - a review by the EUGA Working Group on Laser

Vulvovaginal atrophy (VVA) is a chronic progressive condition that involves the genital and lower urinary tracts, related to the decrease of serum estrogenic levels when menopause occurs. The definition of genitourinary syndrome of menopause (GSM) is a medically more accurate, all-encompassing and publicly acceptable term than VVA. Due to the chronic progressive trend of GSM, symptoms tend to reappear after the cessation of therapy, and frequently long-term treatment is required. First-line therapies include vulvar and vaginal lubricant or moisturizers, and, in the case of failure, low-dose vaginal estrogens are the preferred pharmacological therapy. Populations of patients, such as breast cancer (BC) survivors, are affected by iatrogenic GSM symptoms with concerns about the use of hormonal therapies. The non-ablative erbium:YAG laser and the fractional microablative CO2 vaginal laser are the two main lasers evaluated for GSM treatment. The aim of this comprehensive review is to report the efficacy and safety of Er:YAG and CO2 vaginal lasers for GSM treatment. Vaginal laser therapy has been demonstrated to be effective in restoring vaginal health, improving VVA symptoms and sexual function. The data suggest that both Er:YAG and CO2 vaginal lasers are safe energy-based therapeutic options for management of VVA and/or GSM symptoms in postmenopausal women and BC survivors.

Development and evaluations of the ancestry informative markers of the VISAGE Enhanced Tool for Appearance and Ancestry

The VISAGE Enhanced Tool for Appearance and Ancestry (ET) has been designed to combine markers for the prediction of bio-geographical ancestry plus a range of externally visible characteristics into a single massively parallel sequencing (MPS) assay. We describe the development of the ancestry panel markers used in ET, and the enhanced analyses they provide compared to previous MPS-based forensic ancestry assays. As well as established autosomal single nucleotide polymorphisms (SNPs) that differentiate sub-Saharan African, European, East Asian, South Asian, Native American, and Oceanian populations, ET includes autosomal SNPs able to efficiently differentiate populations from Middle East regions. The ability of the ET autosomal ancestry SNPs to distinguish Middle East populations from other continentally defined population groups is such that characteristic patterns for this region can be discerned in genetic cluster analysis using STRUCTURE. Joint cluster membership estimates showing individual co-ancestry that signals North African or East African origins were detected, or cluster patterns were seen that indicate origins from central and Eastern regions of the Middle East. In addition to an augmented panel of autosomal SNPs, ET includes panels of 85 Y-SNPs, 16 X-SNPs and 21 autosomal Microhaplotypes. The Y- and X-SNPs provide a distinct method for obtaining extra detail about co-ancestry patterns identified in males with admixed backgrounds. This study used the 1000 Genomes admixed African and admixed American sample sets to fully explore these enhancements to the analysis of individual co-ancestry. Samples from urban and rural Brazil with contrasting distributions of African, European, and Native American co-ancestry were also studied to gauge the efficiency of combining Y- and X-SNP data for this purpose. The small panel of Microhaplotypes incorporated in ET were selected because they showed the highest levels of haplotype diversity amongst the seven population groups we sought to differentiate. Microhaplotype data was not formally combined with single-site SNP genotypes to analyse ancestry. However, the haplotype sequence reads obtained with ET from these loci creates an effective system for de-convoluting two-contributor mixed DNA. We made simple mixture experiments to demonstrate that when the contributors have different ancestries and the mixture ratios are imbalanced (i.e., not 1:1 mixtures) the ET Microhaplotype panel is an informative system to infer ancestry when this differs between the contributors.

Driven by need, shaped by access: Heterogeneity in patient profiles and patterns of service utilization in patients with alcohol use disorders

BACKGROUND

Patients with alcohol-use disorders (AUDs) are highly heterogenous and account for an increasing proportion of general medical hospital visits. However, many patients with AUDs do not present with severe medical or psychiatric needs requiring immediate attention. There may be a mismatch between some patients' needs and the available services, potentially driving re-admissions and re-encounters. The current study aims to identify subgroups of AUD patients and predict differences in patterns of healthcare service use (HSU) over time.

METHODS

Latent class analysis (LCA) was conducted using hospital data incorporating sociodemographic, health behavior, clinical, and service use variables to identify subtypes of AUD patients, then class membership was used to predict patterns of HSU.

RESULTS

Four classes were identified with the following characteristics: (1) Patients with acute medical injuries (30 %); (2) Patients with socioeconomic and psychiatric risk factors, (11 %); (3) Patients with chronic AUD with primarily non-psychiatric medical needs (18 %); and (4) Patients with primary AUDs with low medical-treatment complexity (40 %). Negative binomial models showed that Class 4 patients accounted for the highest frequency of service use, including significantly higher rates of emergency department reencounters at 30 days and 12 months.

CONCLUSIONS

The profile and patterns of HSU exhibited by patients in class 4 suggest that these patients have needs which are not currently being addressed in the emergency department. These have implications for how resources are allocated to meet the needs of patients with AUDs, including those who make frequent visits to the emergency department without high acuity medical needs.

Toward Diabetes Device Development That Is Mindful to the Needs of Young People Living With Type 1 Diabetes: A Data- and Theory-Driven Qualitative Study

BACKGROUND

An important strategy to understand young people's needs regarding technologies for type 1 diabetes mellitus (T1DM) management is to examine their day-to-day experiences with these technologies.

OBJECTIVE

This study aimed to examine young people's and their caregivers' experiences with diabetes technologies in an exploratory way and relate the findings to the existing technology acceptance and technology design theories. On the basis of this procedure, we aimed to develop device characteristics that meet young people's needs.

METHODS

Overall, 16 in-person and web-based face-to-face interviews were conducted with 7 female and 9 male young people with T1DM (aged between 12 and 17 years) and their parents between December 2019 and July 2020. The participants were recruited through a pediatric diabetes clinic based at Canberra Hospital. Data-driven thematic analysis was performed before theory-driven analysis to incorporate empirical data results into the unified theory of acceptance and use of technology (UTAUT) and value-sensitive design (VSD). We used the COREQ (Consolidated Criteria for Reporting Qualitative Research) checklist for reporting our research procedure and findings. In this paper, we summarize the key device characteristics that meet young people's needs.

RESULTS

Summarized interview themes from the data-driven analysis included aspects of self-management, device use, technological characteristics, and feelings associated with device types. In the subsequent theory-driven analysis, the interview themes aligned with all UTAUT and VSD factors except for one (privacy). Privacy concerns or related aspects were not reported throughout the interviews, and none of the participants made any mention of data privacy. Discussions around ideal device characteristics focused on reliability, flexibility, and automated closed loop systems that enable young people with T1DM to lead an independent life and alleviate parental anxiety. However, in line with a previous systematic review by Brew-Sam et al, the analysis showed that reality deviated from these expectations, with inaccuracy problems reported in continuous glucose monitoring devices and technical failures occurring in both continuous glucose monitoring devices and insulin pumps.

CONCLUSIONS

Our research highlights the benefits of the transdisciplinary use of exploratory and theory-informed methods for designing improved technologies. Technologies for diabetes self-management require continual advancement to meet the needs and expectations of young people with T1DM and their caregivers. The UTAUT and VSD approaches were found useful as a combined foundation for structuring the findings of our study.

Diagnostic delay of sarcoidosis: Protocol for an integrated systematic review

INTRODUCTION

Sarcoidosis is a rare systemic inflammatory granulomatous disease of unknown cause. It can manifest in any organ. The incidence of sarcoidosis varies across countries, and by ethnicity and gender. Delays in the diagnosis of sarcoidosis can lead to extension of the disease and organ impairment. Diagnosis delay is attributed in part to the lack of a single diagnostic test or unified commonly used diagnostic criteria, and to the diversity of disease manifestations and symptom load. There is a paucity of evidence examining the determinants of diagnostic delay in sarcoidosis and the experiences of people with sarcoidosis related to delayed diagnosis. We aim to systematically review available evidence about diagnostic delay in sarcoidosis to elucidate the factors associated with diagnostic delay for this disease in different contexts and settings, and the consequences for people with sarcoidosis.

METHODS AND ANALYSIS

A systematic search of the literature will be conducted using PubMed/Medline, Scopus, and ProQuest databases, and sources of grey literature, up to 25th of May 2022, with no limitations on publication date. We will include all study types (qualitative, quantitative, and mixed methods) except review articles, examining diagnostic delay, incorrect diagnosis, missed diagnosis or slow diagnosis of all types of sarcoidosis across all age groups. We will also examine evidence of patients' experiences associated with diagnostic delay. Only studies in English, German and Indonesian will be included. The outcomes we examine will be diagnostic delay time, patients' experiences, and factors associated with diagnostic delay in sarcoidosis. Two people will independently screen the titles and abstracts of search results, and then the remaining full-text documents against the inclusion criteria. Disagreements will be resolved with a third reviewer until consensus is reached. Selected studies will be appraised using the Mixed Methods Appraisal Tool (MMAT). A meta-analysis and subgroup analyses of quantitative data will be conducted. Meta-aggregation methods will be used to analyse qualitative data. If there is insufficient data for these analyses, a narrative synthesis will be conducted.

DISCUSSION

This review will provide systematic and integrated evidence on the diagnostic delay, associated factors, and experiences of diagnosis delay among people with all types of sarcoidosis. This knowledge may shed light on ways to improve diagnosis delays in diagnosis across different subpopulations, and with different disease presentations.

ETHICS AND DISSEMINATION

Ethical approval will not be required as no human recruitment or participation will be involved. Findings of the study will be disseminated through publications in peer-reviewed journals, conferences, and symposia.

Neutron star mass estimates from gamma-ray eclipses in spider millisecond pulsar binaries

Reliable neutron star mass measurements are key to determining the equation of state of cold nuclear matter, but such measurements are rare. Black widows and redbacks are compact binaries consisting of millisecond pulsars and semi-degenerate companion stars. Spectroscopy of the optically bright companions can determine their radial velocities, providing inclination-dependent pulsar mass estimates. Although inclinations can be inferred from subtle features in optical light curves, such estimates may be systematically biased due to incomplete heating models and poorly understood variability. Using data from the Fermi Large Area Telescope, we have searched for gamma-ray eclipses from 49 spider systems, discovering significant eclipses in 7 systems, including the prototypical black widow PSR B1957+20. Gamma-ray eclipses require direct occultation of the pulsar by the companion, and so the detection, or significant exclusion, of a gamma-ray eclipse strictly limits the binary inclination angle, providing new robust, model-independent pulsar mass constraints. For PSR B1957+20, the eclipse implies a much lighter pulsar (1.81 ± 0.07 solar masses) than inferred from optical light curve modelling.

Development of a prototype modeling system to estimate the GHG mitigation potential of forest and wildfire management

Having recently experienced the three worst wildfire seasons in British Columbia's history in 2017, 2018 and 2021, and anticipating more severe impacts in the future, a key Carbon (C) research priority is to develop reliable models to explore options and identify a portfolio of regionally differentiated solutions for wildfire and forest management. We contribute to this effort by developing a prototype integrated C modeling framework which includes future wildfires that respond to forest stand characteristics and wildfire history. Model validation evaluated net GHG emissions relative to a 'do-nothing' baseline for several management scenarios and included emissions from forest ecosystems, harvested wood products and substitution benefits from avoided fossil fuel burning and avoided emissions-intensive materials. Data improvements are needed to accurately quantify the baseline and scenario GHG emissions, and to identify trade-offs and uncertainties. • A Fire Tolerant scenario included post-fire restoration with planting of climatically suitable fire-resistant species and salvage harvest in place of clearcut harvest.

1119. Covid-19 Mab Use in High-Risk Pediatric Patients

Background

Effective therapeutic agents for the treatment of COVID-19 have been investigated since the onset of the pandemic. Monoclonal antibodies targeting the spike protein of SARS-CoV-2 have been developed for treatment of mild or moderate COVID disease in high-risk populations. Despite widespread use in the adult population, data are limited on the safety and efficacy of monoclonal antibody infusions in the adolescent and young adult population.

Methods

Patients who received bamlanivimab, bamlanivimab-etesevimab, casirivimab-imdevimab, or sotrovimab for treatment of mild COVID disease at Cincinnati Children’s Hospital Medical Center from 5/1/2020 through 3/1/2022 were identified retrospectively. In accordance with the FDA EUA, patients were eligible for monoclonal antibody administration if they were ≥12 years of age, weighed ≥40kg, and were at high risk of progressing to severe disease or hospitalization.

Results

Ninety-four patients received monoclonal antibody therapy, of which 14 (13.5%) received either bamlanivimab or bamlanivimab-etesevimab, 54 (51.9%) received casirivimab-imdevimab, and 26 (25%) received sotrovimab. Ten patients (10.6%) experienced one or more adverse events. Of those, 2 (14.3%) received either bamlanivimab or bamlanivimab-etesivimab, 7 (12.9%) received casirivimab-imdevimab, and 1 (3.8%) received sotrovimab. Most common symptoms include rash, nausea, and throat irritation (table R1), the majority (90%) of which were mild, either self-resolving with infusion cessation (60%) or persistent but requiring no medical intervention (30%) (table R2). Of the patients who experienced adverse events, only 1 (10%) received medical intervention - epinephrine. No life-threatening events or deaths occurred. Within 90 days of receiving a monoclonal antibody, 15 patients (15.9%) required additional medical care for ongoing COVID symptoms (table R3). Eight (53.3%) of these were either hospitalized or received escalation of care while already in the hospital. Table R1.

Infusion-related adverse events. Of note, several patients had more than one symptom. Table R2.

Classification of adverse events by grade and monoclonal antibody. Grade I events are defined as mild and generally not bothersome. Grade II events are defined as moderate: bothersome, but not dangerous. Grade III events are defined as medically significant, but not immediately life-threatening, and often require medical intervention. Table R3.

Patients who required additional medical care for ongoing COVID-19 symptoms within 90 days of receiving a monoclonal antibody.

Conclusion

Overall, monoclonal antibodies are safe, largely well-tolerated COVID-19 therapies in high-risk adolescent and young adult populations.

Opportunities for primary health care: a qualitative study of perinatal health and wellbeing during bushfire crises

BACKGROUND

During the summer of 2019/2020, Australia experienced a catastrophic wildfire season that affected nearly 80% of Australians either directly or indirectly. The impacts of climate crisis on perinatal health have only recently begun to receive attention. The objective of this study was to understand experiences of perinatal women during the bushfire and smoke events of 2019-2020 regarding health, health care, and public health messaging.

METHODS

Semistructured interviews were conducted by phone or web conferencing platforms with 43 participants living in the south-east of Australia who were either pregnant or who had recently had a baby during the 2019/2020 fires.

RESULTS

The health impacts on participants of the fires, associated smoke, and evacuations for some, were both physical and psychological. Many participants sought information regarding how to protect their own health and that of their unborn/recently born children, but reported this difficult to find.

CONCLUSIONS

Pregnant women and new mothers exposed to bushfire events are a risk group for adverse physical and psychological outcomes. At the time of the 2019/2020 Australian bushfires, exposed women could not easily access evidence-based information to mitigate this risk. Family practitioners are well placed to provide pregnant women and new mothers with this sought-after information, but they need to be prepared well in advance of future similar events.

Diagnostic delay of myositis: an integrated systematic review

BACKGROUND

Idiopathic inflammatory myopathies (IIM) are a heterogenous group of rare muscular autoimmune diseases characterised by skeletal muscle inflammation with possible diagnostic delay. Our aim was to review the existing evidence to identify overall diagnostic delay for IIM, factors associated with diagnostic delay, and people's experiences of diagnostic delay.

METHODS

Three databases and grey literature sources were searched. Diagnostic delay was defined as the period between the onset of symptoms and the year of first diagnosis of IIM. We pooled the mean delay using random effects inverse variance meta-analysis and performed subgroup analyses.

RESULTS

328 titles were identified from which 27 studies were included. Overall mean diagnostic delay was 27.91 months (95% CI 15.03-40.79, I2 = 99%). Subgroup analyses revealed a difference in diagnostic delay between non-inclusion body myositis (IBM) and IBM types. There was no difference in diagnostic delay between studies in which myositis specific autoantibodies (MSA) were tested or not tested. In countries with gatekeeper health systems, where primary care clinicians authorize access to specialty care, people experienced longer periods of diagnostic delay than people with IIM in countries with non-gatekeeper systems. While studies discussed factors that may influence diagnostic delay, significant associations were not identified. No qualitative studies examining people's experiences of diagnostic delay were identified.

CONCLUSION

Diagnostic delay of IIM has extensive impacts on the quality of life of people living with this disease. Understanding the experiences of people with IIM, from symptom onset to diagnosis, and factors that influence diagnostic delay is critical to inform clinical practice and training activities aimed at increasing awareness of this rare disease and expediting diagnosis.

Rare Presentation of Crescentic Glomerulonephritis in a 4-Week-Old Infant

Introduction/Objective

Rapidly progressive glomerulonephritis is characterized by sudden decline in renal function and glomerular crescents. Crescentic glomerulonephritis develops along three pathways: glomerular basement membrane antibody in situ deposition , circulating immune complex glomerular deposition, or pauci-immune (typically ANCA-associated). For the latter, histopathologic diagnosis is more frequently obtained in adults than in children. Therefore, tissue examination opportunities in infants and neonates is exceptionally rare.

Methods/Case Report

Here we report the autopsy findings from a 4-week-old infant who was part of dichorionic, diamniotic twin pregnancy and born prematurely at 34 weeks to a 30-year-old G6P4 mother. The infant initially presented with labored breathing and poor oral intake, but subsequently developed Enterobactor meningoencephalitis and sepsis, leading to extensive strokes andstatus epilepticus. An infectious source was not identified clinically, and evaluation for an underlying immunodeficiency was indeterminant. The mother had no known autoimmune diseases or antenatal infections. At autopsy, kidney histology showed focal fibrinoid necrosis and/or cellular and fibrocellular crescents (~5%), especially mid to deep cortex. Intracapillary hypercellularity was minimal to absent. Mesangial matrix was not expanded. The interstitium contained patchy inflammatory infiltrates (mononuclear > polymorphonuclear). Direct immunofluorescence (IF) on pronase-treated paraffin sections did not show glomerular deposition of IgG, IgA, or IgM. Electron microscopy (EM) did not show electron dense deposits despite autolysis.

Results (if a Case Study enter NA)

NA.

Conclusion

The absence of immune complex deposition by IF and dense deposits by EM favors the rare diagnosis of pauci-immune glomerulonephritis in this case of neonatal crescentic glomerulonephritis associated with Enterobactor meningoencephalitis and sepsis, with no associated maternal autoimmune disease or antenatal infections.

Eurasiaplex-2: Shifting the focus to SNPs with high population specificity increases the power of forensic ancestry marker sets

To compile a new South Asian-informative panel of forensic ancestry SNPs, we changed the strategy for selecting the most powerful markers for this purpose by targeting polymorphisms with near absolute specificity - when the South Asian-informative allele identified is absent from all other populations or present at frequencies below 0.001 (one in a thousand). More than 120 candidate SNPs were identified from 1000 Genomes datasets satisfying an allele frequency screen of ≥ 0.1 (10 % or more) allele frequency in South Asians, and ≤ 0.001 (0.1 % or less) in African, East Asian, and European populations. From the candidate pool of markers, a final panel of 36 SNPs, widely distributed across most autosomes, were selected that had allele frequencies in the five 1000 Genomes South Asian populations ranging from 0.4 to 0.15. Slightly lower average allele frequencies, but consistent patterns of informativeness were observed in gnomAD South Asian datasets used to validate the 1000 Genomes variant annotations. We named the panel of 36 South Asian-specific SNPs Eurasiaplex-2, and the informativeness of the panel was evaluated by compiling worldwide population data from 4097 samples in four genome variation databases that largely complement the global sampling of 1000 Genomes. Consistent patterns of allele frequency distribution, which were specific to South Asia, were observed in all populations in, or closely sited to, the Indian sub-continent. Pakistani populations from the HGDP-CEPH panel had markedly lower allele frequencies, highlighting the need to develop a statistical system to evaluate the ancestry inference value of counting the number of population-specific alleles present in an individual.

The current understanding of precision medicine and personalised medicine in selected research disciplines: study protocol of a systematic concept analysis

INTRODUCTION

The terms 'precision medicine' and 'personalised medicine' have become key terms in health-related research and in science-related public communication. However, the application of these two concepts and their interpretation in various disciplines are heterogeneous, which also affects research translation and public awareness. This leads to confusion regarding the use and distinction of the two concepts. Our aim is to provide a snapshot of the current understanding of these concepts.

METHODS AND ANALYSIS

Our study will use Rodgers' evolutionary concept analysis to systematically examine the current understanding of the concepts 'precision medicine' and 'personalised medicine' in clinical medicine, biomedicine (incorporating genomics and bioinformatics), health services research, physics, chemistry, engineering, machine learning and artificial intelligence, and to identify their respective attributes (clusters of characteristics) and surrogate and related terms. A systematic search of the literature will be conducted for 2016-2022 using databases relevant to each of these disciplines: ACM Digital Library, CINAHL, Cochrane Library, F1000Research, IEEE Xplore, PubMed/Medline, Science Direct, Scopus and Web of Science. These are among the most representative databases for the included disciplines. We will examine similarities and differences in definitions of 'precision medicine' and 'personalised medicine' in the respective disciplines and across (sub)disciplines, including attributes of each term. This will enable us to determine how these two concepts are distinguished.

ETHICS AND DISSEMINATION

Following ethical and research standards, we will comprehensively report the methodology for a systematic analysis following Rodgers' concept analysis method. Our systematic concept analysis will contribute to the clarification of the two concepts and distinction in their application in given settings and circumstances. Such a broad concept analysis will contribute to non-systematic syntheses of the concepts, or occasional systematic reviews on one of the concepts that have been published in specific disciplines, in order to facilitate interdisciplinary communication, translational medical research and implementation science.

A Good start in life: Effectiveness of integrated multicomponent multisector support on early child development—Study protocol

Introduction

Early childhood experiences have a lifelong impact on a child’s future. Social and environmental experiences and interactions have a profound relational effect on children’s physical and mental health which transfers agency to parents, caregivers and duty-bearers to care for the child’s welfare. In the Australian context early child development indices have been in decline in some communities. Hence, there is a sense of urgency to reverse these trends from an integrated perspective. A multisector, multi component program of interventions named A Good Start in Life is proposed and is being tested in the Australian Capital Territory across suburbs with high levels of early childhood development disadvantage. The aim of this study is to evaluate the outcomes and processes related to targeted interventions, designed to integrate child and family services within the local district and embed allied health programs into early childhood education, care services and playgroups.

Methods and analysis

The Good Start in Life study will use a quasi-experimental design (with a matched control geographical area) consisting of a combination of interventions that will build multisectoral collaboration across education, health and social services that connect and support families with children from birth to 5 years. The control area will be matched on demographic characteristics and early child development outcomes and trends over the pre-intervention period. Evaluation data will be collected at baseline, and then on an annual basis for a further three years. A mixed methods approach will be used to evaluate delivery processes: quantitative (checklists, questionnaires) and qualitative methods (observations, focus groups and key stakeholder interviews). Effectiveness of the programme will be evaluated by comparing early child development outcomes between the comparator areas from the Australian Early Development Census in 2024. The primary focus will be on reducing the number of children who are developmentally vulnerable on at least one early development index (EDI). Separate tests will be conducted for significant differences in the percentage of children at risk in each of the five individual EDI domains. These domains are physical health and wellbeing, social competence, emotional maturity, language and cognitive skills, and communication and general knowledge.

COVID-19 and mental health in Australia - a scoping review

Background

The COVID-19 outbreak has spread to almost every country around the world and caused more than 3 million deaths. The pandemic has triggered enormous disruption in people’s daily lives with profound impacts globally. This has also been the case in Australia, despite the country’s comparative low mortality and physical morbidity due to the virus. This scoping review aims to provide a broad summary of the research activity focused on mental health during the first 10 months of the pandemic in Australia.

Results

A search of the Australian literature was conducted between August-November 2020 to capture published scientific papers, online reports and pre-prints, as well as gaps in research activities. The search identified 228 unique records in total. Twelve general population and 30 subpopulation group studies were included in the review.

Conclusions

Few studies were able to confidently report changes in mental health driven by the COVID-19 context (at the population or sub-group level) due to a lack of pre-COVID comparative data and non-representative sampling. Never-the-less, in aggregate, the findings show an increase in poor mental health over the early period of 2020. Results suggest that young people, those with pre-existing mental health conditions, and the financially disadvantaged, experienced greater declines in mental health. The need for rapid research appears to have left some groups under-researched (e.g. Culturally and Linguistically Diverse populations and Indigenous peoples were not studied), and some research methods under-employed (e.g. there was a lack of qualitative and mixed-methods studies). There is a need for further reviews as the follow-up results of longitudinal studies emerge and understandings of the impact of the pandemic are refined.

Diagnostic delay of myositis: protocol for an integrated systematic review

INTRODUCTION

Idiopathic inflammatory myopathies (IIM). described as 'inflammatory myositis', are a heterogeneous group of rare muscular autoimmune diseases characterised by skeletal muscle inflammation. Its complex characteristics with lack of accurate diagnostic tests, unified classification system and comprehensive widely used diagnostic criteria could lead to diagnostic delay. This study will review diagnostic delay in myositis and provide an overview and clearer insight of patients' experiences, causes and consequences of diagnostic delay in myositis.

METHODS AND ANALYSIS

The literature source will be a systematic search of PubMed/MEDLINE, Scopus, ProQuest and sources of grey literature, conducted from database inception to December 2021 without restrictions on publication date. All study types (qualitative and quantitative) except review articles, examining diagnostic delay, incorrect diagnosis, missed diagnosis or slow diagnosis of all types of myositis in all ages will be included. Evidence of patients' experiences associated with diagnostic delay will also be examined. Studies in languages other than English, German and Indonesian will be excluded. Outcomes will be diagnostic delay time, patients' experiences, and causes and consequences associated with diagnostic delay in myositis. Two review authors will independently screen the titles and abstracts of search results against the inclusion criteria. The Mixed Methods Appraisal Tool (MMAT) will be used to appraise selected studies. Two independent authors will extract data using a prepiloted data extraction tool. If sufficient quantitative data is available, a meta-analysis will be conducted along with subgroup analysis including pooled diagnostic delay in each type of myositis. Qualitative data will be analysed in line with meta-aggregation methods. If data is insufficient, a narrative synthesis will be conducted.

ETHICS AND DISSEMINATION

As this work is a systematic review, ethical approval was not required. Findings of the study will be disseminated through publications in peer-reviewed journals, conferences and symposia.

Effect of medical education on European psychiatrists’ knowledge in management of major depressive disorder and psychiatric emergencies

Introduction

The challenge for psychiatrists is keeping up to date with the latest clinical trial data in managing major depressive disorder (MDD) and psychiatric emergencies.

Objectives

We evaluated whether an online educational video lecture directed at psychiatrists, could improve knowledge and confidence regarding management of psychiatric emergencies associated with MDD.

Methods

Educational effect was assessed using a 3-question repeated pairs, pre/post assessment survey. A paired-samples t-test was conducted to assess overall number correct and confidence change. A McNemar’s test was conducted to assess question-level significance. P values < 0.05 are statistically significant. Cohen’s d test was used to estimate the magnitude of effect of education. The activity launched on 8 April 2021, and preliminary data analysed as of 24 June 2021.

Results

807 psychiatrists participated in the programme, of which 150 completed the pre- and post-assessment test. An average overall correct response rate of 44% pre- increased to 74% post- (67% relative increase, P<0.001; Cohen’s d = 0.91). Knowledge on the burden of suicide and MDD improved from 38% pre- to 85% post- (124% relative increase,P<0.001). Knowledge regarding clinical data for novel therapies for use in psychiatric emergencies improved from 47% pre- to 68% post- (45% relative increase, P<0.01). Knowledge regarding signs of suicidal intent in patients with MDD improved from 49% pre- to 71% (45% relative increase, P<0.001) following education.

Conclusions

This study demonstrates the positive effect of online medical education on psychiatrists’ knowledge in contemporary management of psychiatric emergencies associated with MDD in Europe.

Effect of medical education on European primary care physicians’ knowledge in management of major depressive disorder and psychiatric emergencies

Introduction

The challenge for primary care physicians (PCPs) is keeping up to date in managing major depressive disorder (MDD) and psychiatric emergencies.

Objectives

We evaluated whether an online educational video lecture directed at PCPs, could improve knowledge and confidence regarding management of psychiatric emergencies associated with MDD.

Methods

Educational effect was assessed using a 3-question repeated pairs, pre/post assessment survey. A paired-samples t-test was conducted to assess overall number correct and confidence change. A McNemar’s test was conducted to assess question-level significance. P values < 0.05 are statistically significant. Cohen’s d test was used to estimate the magnitude of effect of education. The activity launched on 8 April 2021, and preliminary data analysed as of 24 June 2021.

Results

511 PCPs participated in the programme, of which 86 PCPs completed the pre- and post-assessment test. An average overall correct response rate of 28% pre- increased to 64% post- (129% relative increase, P<0.001; Cohen’s d = 1.13). Knowledge on the burden of suicide and MDD improved from 23% pre- to 87% post- (278% relative increase,P<0.001). Knowledge regarding clinical data for novel therapies for use in psychiatric emergencies improved from 29% pre- to 50% post- (72% relative increase, P<0.01). Knowledge regarding signs of suicidal intent in patients with MDD improved from 31% pre- to 53% (71% relative increase, P<0.001) following education.

Conclusions

This study demonstrates the positive effect of online medical education on PCPs’ knowledge and confidence in contemporary management of psychiatric emergencies associated with MDD in Europe.

ACT Transition from Hospital to Home Orthopaedic Survey: a cross-sectional survey of unplanned 30-day readmissions for patients having total hip arthroplasty

OBJECTIVES

The aim of this study was to identify patient, hospital and transitional factors associated with unplanned 30-day readmissions in patients who had a total hip arthroplasty (THA).

DESIGN

A cross-sectional survey was performed. All patients attending a 6-week follow-up after a THA in the Australian Capital Territory (ACT) at four public and private clinics in the ACT from 1 February 2018 to 31 January 2019, were invited to complete an ACT Transition from Hospital to Home Orthopaedic Survey.

PARTICIPANTS

Within the ACT, 431 patients over the age of 16 attending their 6-week post-surgery consultation following a THA entered and completed the survey (response rate 77%).

PRIMARY OUTCOME MEASURE

The primary outcome measure was self-reported readmissions for any reason within 30 days of discharge after a THA. Multiple logistic regression was used to estimate ORs of factors associated with unplanned 30-day readmissions.

RESULTS

Of the 431 participants (representing 40% of all THAs conducted in the ACT during the study period), 27 (6%) were readmitted within 30 days of discharge. After controlling for age and sex, patients who did not feel rested on discharge were more likely to be readmitted within 30 days than those who felt rested on discharge (OR=5.75, 95% CI: (2.13 to 15.55), p=0.001). There was no association between post-hospital syndrome (ie, in-hospital experiences of pain, sleep and diet) overall and readmission. Patients who suffered peripheral vascular disease (PVD) were significantly more likely to have an unplanned 30-day readmission (OR=16.9, 95% CI: (3.06 to 93.53), p=0.001). There was no significant difference between private and public patient readmissions CONCLUSIONS: Hospitals should develop strategies that maximise rest and sleep during patients' hospital stay. Diagnosis and optimum treatment of pre-existing PVD prior to THA should also be a priority to minimise the odds of subsequent unplanned readmissions.

Understanding factors affecting 30-day unplanned readmissions for patients undergoing total knee arthroplasty (TKA): the ACT Transition from Hospital to Home Orthopaedics Survey

OBJECTIVES

The aim of this study was to investigate factors associated with unplanned 30-day readmissions following a total knee arthroplasty (TKA), including association with post-hospital syndrome, patient enablement and transition from hospital to home.

DESIGN, SETTING AND PARTICIPANTS

A cross-sectional written survey of public and private patients attending a 6-week follow-up appointment after TKA at one of four clinical services in the Australian Capital Territory (ACT) between 1 February 2018 and 31 January 2019. Multiple logistic regression analyses were used to measure associations between patient, hospital and transitional care factors with unplanned 30-day readmissions, while controlling for known confounders.

RESULTS

Of the 380 participants who completed the survey (n=380, 54% of TKAs undertaken over the study period), 3.4% (n=13; 95% CI: 1.8 to 5.8) were subsequently readmitted within 30 days of discharge after a primary hospitalisation. Public patients were significantly more likely to be readmitted within 30 days compared with private patients (adjusted OR=6.31, 95% CI: 1.59 to 25.14, p=0.009), and patients who attended rehabilitation were significantly less likely to be readmitted within 30 days of discharge than those who did not (adjusted OR=0.16, 95% CI: 0.04 to 0.57, p=0.005). There were no associations between post-hospital syndrome or patient enablement and 30-day readmissions in this study.

CONCLUSION

Reasons underlying the difference in unplanned readmission rates for public versus private patients need to be explored, including differences in surgical waiting times and the consequences for impairment and disease complexity. Strategies to foster increased participation post-surgical rehabilitation programmes need to be developed as an avenue to mitigate the burden of unplanned 30-day readmissions on individuals and health systems.

Ethnic differences in success at application for consultant posts among United Kingdom physicians from 2011 to 2019: a retrospective cross-sectional observational study

OBJECTIVES

To identify associations between success following application for consultant physician posts and demographic factors.

DESIGN

Logistic regression analysis of nationwide survey data.

SETTING

United Kingdom (UK) physicians with a recent certificate of completion of training (CCT).

PARTICIPANTS

All UK trainee physicians who received a CCT between 2010 and 2019 were surveyed. Respondents were excluded if they had not applied for a consultant post or if application data were incomplete.

MAIN OUTCOME MEASURES

The primary outcome measure was success over the entire consultant application process, i.e. shortlisted and offered the post following the first application. Secondary outcomes were: shortlisted following first application and offered a consultant post at first interview.

RESULTS

From 7037 CCT holders surveyed, 50.7% responded. While 1198 (59.7%) respondents were white, 760 (37.9%) were from minority ethnic groups and 50 (3.5%) were of unknown ethnicity. Primary medical qualification (PMQ) country was the UK in 75.3% (n = 1512). On multivariable logistic regression analysis the independent negative associations with success were: minority ethnicity (odds ratio [OR] 0.55, 95% confidence interval [CI] 0.43-0.71); p < 0.001) vs. white; PMQ from Europe (OR 0.47, 95% CI 0.28-0.79; p = 0.004) or Asia (OR 0.68, 95% CI 0.49-0.96; p = 0.027) vs. UK PMQ; year of CCT 2012 (OR 0.40, 95% CI 0.24-0.68; p = 0.001), 2013 (OR 0.39, 95% CI 0.23-0.65; p < 0.001), and 2014 (OR 0.26, 95% CI 0.15-0.43; p < 0.001) vs. 2019. Specialties associated with lower success rates included Cardiology, Endocrinology, Genitourinary medicine, Palliative care, Renal and Respiratory, compared to Acute medicine.

CONCLUSIONS

Minority ethnic group candidates for consultant physician posts had lower success rates compared to white candidates after correction for important variables including specialty, time from and country of PMQ. This finding requires further evaluation to identify the causes for this variation.

Communicating Endometriosis Pain in France and Australia: An Interview Study

Endometriosis is characterized by persistent, fluctuating pain associated with menstruation, a biological function which is socially invisible. The degree and quality of pain cannot easily be measured, observed, or documented. Difficulties in communicating pain pose particular challenges when seeking diagnosis and support from health professionals. In this paper we explore the experiences and characterization of pain by thirteen Australian and thirteen French women with endometriosis. Data were collected through semi-structured interviews using a life-history approach to illness symptoms, diagnosis and treatment. We explore the experiences of women with endometriosis in two phases: from onset of symptoms to seeking advice from a clinician, and from first consulting a clinician to receiving a diagnosis. On average, initial pain symptoms were identified 2.1 years before consulting a health practitioner, after which women reported pain symptoms 8.5 years prior to diagnosis; that is, the time between consulting a clinician and receiving a diagnosis was almost four times the period between experiencing symptoms and consulting a doctor. Pain was often “made real” to doctors by findings consistent with endometriosis on ultrasound and MRI, mostly used in France, or laparoscopy, the predominant diagnostic tool in Australia. No woman described her practitioner using standardized pain assessment tools. Thus, the validation of pain relies largely on disease visibility and the clinician-classified degree of severity rather than self-reported grades of pain or impact on activities of daily living. The invisible and enigmatic pain of this chronic women's disease remains difficult to communicate to doctors, and the recognition of severe pain is often key to timely diagnostic procedures. Clinicians need to be more proactive about severe pain related to menstruation, taking into consideration women's individual circumstances, and maintain a high index of suspicion of underlying endometriosis as a condition characterized primarily by pain.

Bushfire Smoke in Our Eyes: Community Perceptions and Responses to an Intense Smoke Event in Canberra, Australia

The 2019–20 bushfires that raged in eastern Australia were an overwhelming natural disaster leading to lives lost or upended, and communities destroyed. For almost a month, Canberra, Australia's capital city in the Australian Capital Territory (ACT), was obscured by smoke from fires which threatened the outer suburbs. While smoke itself is experientially different from many natural disasters, it nevertheless poses a significant public health threat. As the impact of extended bushfire smoke in an urban setting is relatively unexplored we aimed to capture the individual and community-level experiences of the event and their importance for community and social functioning. We responded rapidly by conducting semi-structured interviews with a range of Canberra residents who, due to their personal or social circumstances, were potentially vulnerable to the effects of the smoke. Three major themes emerging from the narratives depicted disruption to daily life, physical and psychological effects, and shifting social connectedness. This study highlighted the ambiguous yet impactful nature of a bushfire smoke event, and identified four simple key messages that may be critically relevant to policy making in preparation for similar smoke events in the future.

Intertwined like a double helix: A meta-synthesis of the qualitative literature examining the experiences of living with someone with multiple sclerosis

Background

Multiple sclerosis (MS) is a chronic serious condition of uncertain course and outcome. There is relatively little literature on the experiences of people who live with a person with MS. They inhabit a locus of care that spans caring for (a relational act) and caring about (a moral stance, addressing fairness, compassion and justice) the person with MS.

Methods

Using the theoretical lens of personhood, we undertook a scoping review and meta‐synthesis of the qualitative literature on the experiences of people who live with a person with MS, focusing on the nature of, and constraints upon, caring.

Results

Of 330 articles, 49 were included in the review. We identified five themes. One of these—seeking information and support—reflects the political economy of care. Two are concerned with the moral domain of care: caring as labour and living with uncertainty. The final two themes—changing identities and adapting to life with a person with MS—point to the negotiation and reconstitution of personhood for both the person with MS and the people they live with.

Conclusion

People with MS are embedded in relational social networks of partners, family and friends, which are fundamental in the support of their personhood; the people who live with them are ‘co‐constituents of the patient's identity’ assisting them to make sense of their world and self in times of disruption due to illness. Support services and health care professionals caring for people with MS are currently very much patient‐centred; young people in particular report that their roles are elided in the health system's interaction with a parent with MS. There is a need to look beyond the person with MS and recognize the relational network of people who surround them and broaden their focus to encompass this network.

Patient and Public Involvement

Our research team includes four members with MS and two members with lived experience of living or working with people with MS. A third person (not a team member) who lives with a partner with MS provided feedback on the paper.

COVID-19: using chest CT of major trauma patients to monitor and evaluate the second wave in London and the development of routine monitoring in practice

AIM

To follow-up previous work evaluating incidental findings of COVID-19 signs on computed tomography (CT) images of major trauma patients to include the second wave prior to any major effects from vaccines.

MATERIALS AND METHODS

The study population included all patients admitted following major trauma between 1 January 2020 and 28 February 2021 with CT including the lungs (n=1776). Major trauma patients admitted pre-COVID-19 from alternate months from January 2019 to November 2019 comprised a control group (n=837). The assessing radiologists were blinded to the time period and used double reading in consensus to determine if the patient had signs of COVID-19. Lung appearances were classified as no evidence of COVID-19, minor signs, or major signs.

RESULTS

The method successfully tracked the second wave of the COVID-19 pandemic in London. The estimated population affected by the disease based on those with major signs was similar to estimates of the proportion of the population in London with antibodies (around 30% by end February 2021) and the total of major and minor signs produced a much higher figure of 68%, which may include all those with both antibody and just T-cell responses.

CONCLUSIONS

Incidental findings on CT from major trauma patients may provide a novel and sensitive way of tracking the virus. It is recommended that all major trauma units include a simple question on signs of COVID-19 to provide an early warning system for further waves.

A framework for involving coproduction partners in research about young people with type 1 diabetes

Background

Involvement of end‐users in research can enhance its quality, relevance, credibility and legitimacy; however, the processes through which these changes occur are unclear. Our aim was to explore a coproduction research team's experiences of their involvement in research about young people with type 1 diabetes mellitus (T1DM).

Methods

Semi‐structured interviews conducted with two young people with T1DM, two parents, one diabetes educator, one endocrinologist‐scientist and one research‐engineer explored experiences of coproduction research and its impact on both the research and the participants. Drawing on grounded theory, we undertook inductive analysis and storyline mapping to develop a theorized framework of mechanisms supporting the process of coproduction in T1DM research with young people.

Findings

The framework involving coproduction partners in research about young people with type 1 diabetes centres on the unique expertize that different team members bring to the research and describes conditions that enable expert contributions through the enactment of a variety of expert roles. The framework also describes outcomes—the impact of the expert contributions on both the research and the team members involved.

Conclusion

The findings of this small exploratory study provide a sound foundation to develop further understanding about structures and processes that are integral for the success of coproduction research teams. The framework may provide a guide for researchers planning to incorporate coproduction, on elements that are important for this model of research to succeed. It may also inform coproduction impact assessment research and be used for hypothesis testing and expansion in future studies.

Lessons for the global primary care response to COVID-19: a rapid review of evidence from past epidemics

BACKGROUND

COVID-19 is the fifth and most significant infectious disease epidemic this century. Primary health care providers, which include those working in primary care and public health roles, have critical responsibilities in the management of health emergencies.

OBJECTIVE

To synthesize accounts of primary care lessons learnt from past epidemics and their relevance to COVID-19.

METHODS

We conducted a review of lessons learnt from previous infectious disease epidemics for primary care, and their relevance to COVID-19. We searched PubMed/MEDLINE, PROQUEST and Google Scholar, hand-searched reference lists of included studies, and included research identified through professional contacts.

RESULTS

Of 173 publications identified, 31 publications describing experiences of four epidemics in 11 countries were included. Synthesis of findings identified six key lessons: (i) improve collaboration, communication and integration between public health and primary care; (ii) strengthen the primary health care system; (iii) provide consistent, coordinated and reliable information emanating from a trusted source; (iv) define the role of primary care during pandemics; (v) protect the primary care workforce and the community and (vi) evaluate the effectiveness of interventions.

CONCLUSIONS

Evidence highlights distinct challenges to integrating and supporting primary care in response to infectious disease epidemics that have persisted over time, emerging again during COVID-19. These insights provide an opportunity for strengthening, and improved preparedness, that cannot be ignored in a world where the frequency, virility and global reach of infectious disease outbreaks are increasing. It is not too soon to plan for the next pandemic, which may already be on the horizon.

Managing type 1 diabetes during the COVID-19 pandemic is a team effort: a qualitative study of the experiences of young people and their parents

Objective

To explore the experiences of young people with type 1 diabetes mellitus (T1DM) and their parents in accessing integrated family-centred care in the Australian Capital Territory during the COVID-19 pandemic.

Methods and analysis

This is a pragmatic, qualitative descriptive study for which we conducted semistructured interviews with 11 young people with T1DM aged 12-16 years and 10 of their parents who attended an outpatient diabetes service in Canberra, Australia. Thematic analysis was conducted in accordance with the methods outlined by Braun and Clarke.

Results

Three themes were identified: feeling vulnerable, new ways of accessing care and trust in the interdisciplinary diabetes healthcare team. Participants believed having T1DM made them more vulnerable to poor outcomes if they contracted COVID-19, resulting in avoidance of face-to-face care. Telephone consultations offered a convenient and contact-free way to undertake 3-monthly reviews. The greatest difference between telephone and face-to-face consultations was not having access to the whole interdisciplinary diabetes support team at one appointment, physical examination and haemoglobin A1c testing during telehealth consultations. Participants trusted that clinicians would arrange face-to-face meetings if required. Some felt a video option might be better than telephone, reflecting in part the need for more training in communication skills for remote consultations.

Conclusion

Young people with T1DM and their parents require collaborative care and contact with multiple healthcare professionals to facilitate self-management and glycaemic control. While telephone consultations offered convenient, safe, contact-free access to healthcare professionals during the COVID-19 pandemic, the added value of video consultations and facilitating access to the whole interdisciplinary diabetes support team need to be considered in future clinical implementation of telehealth.

Evaluation of a custom QIAseq targeted DNA panel with 164 ancestry informative markers sequenced with the Illumina MiSeq

Introduction of new methods requires meticulous evaluation before they can be applied to forensic genetic case work. Here, a custom QIAseq Targeted DNA panel with 164 ancestry informative markers was assessed using the MiSeq sequencing platform. Concordance, sensitivity, and the capability for analysis of mixtures were tested. The assay gave reproducible and nearly concordant results with an input of 10 and 2 ng DNA. Lower DNA input led to an increase in both locus and allele drop-outs, and a higher variation in heterozygote balance. Locus or allele drop-outs in the samples with less than 2 ng DNA input were not necessarily associated with the overall performance of a locus. Thus, the QIAseq assay will be difficult to implement in a forensic genetic setting where the sample material is often scarce and of poor quality. With equal or near equal mixture ratios, the mixture DNA profiles were easily identified by an increased number of imbalanced heterozygotes. For more skewed mixture ratios, the mixture DNA profiles were identified by an increased noise level. Lastly, individuals from Great Britain and the Middle East were investigated. The Middle Eastern individuals showed a greater affinity with South European populations compared to North European populations.

Strengthening National Capacities for Pandemic Preparedness: A Cross-Country Analysis of COVID-19 Cases and Deaths

The International Health Regulation-State Party Annual Reporting (IHR-SPAR) and the Global Health Security Index (GHSI)) have been developed to aid in strengthening national capacities for pandemic preparedness. We examine the relationship between country-level rankings on these two indices, along with two additional indices (the Universal Health Coverage Service Coverage Index and World Bank Worldwide Governance Indicator (n = 195)) and compared them to the country-level reported COVID-19 cases and deaths (Johns Hopkins University (JHU) COVID-19 Dashboard) through 17 June 2020. Ordinary least squares regression models were used to compare weekly reported COVID-19 case and death rates per million in the first 12 weeks of the pandemic between countries classified as low, middle, and high ranking on each index, while controlling for country socio-demographic information. Countries with higher GHSI and IHR-SPAR index scores experienced fewer reported COVID-19 cases and deaths, but only for the first 8 weeks after the country's first case. For the GHSI, this association was further limited to countries with populations below 69.4 million. For both the GHSI and IHR-SPAR, countries with a higher sub-index score in human resources for pandemic preparedness reported fewer COVID-19 cases and deaths in the first 8 weeks after the country's first reported case. The UHC-SCI and WGI country-level rankings were not associated with COVID-19 outcomes. The associations between GHSI and IHR-SPAR scores and COVID-19 outcomes observed in this study demonstrate that these two indices, although imperfect, may have value, especially in countries with a population under 69.4 million people for the GHSI. Preparedness indices may have value; however, they should continue to be evaluated as policymakers seek to better prepare for future global public health crises.

'They're getting a taste of our world': A qualitative study of people with multiple sclerosis' experiences of accessing health care during the COVID-19 pandemic in the Australian Capital Territory

Background

People with multiple sclerosis (MS), who are often immunocompromised, require complex care and engage with a variety of health‐care providers to manage their health.

Objective

To elucidate people with MS' experiences of accessing health care during the COVID‐19 pandemic in Australia.

Design

A qualitative study involving semi‐structured interviews and thematic analysis.

Settings and participants

Eight adults with a clinical diagnosis of MS participated in telephone or video call interviews between June and July 2020.

Results

Participants were aware that having MS made them more vulnerable to contracting COVID‐19. In some cases, usual care was postponed or not sought. Some circumstances warranted the risk of a face‐to‐face consultation. Benefits of telehealth consultations included improved access, convenience and being contact‐free. In comparison with video consultations, those via telephone were considered less personal and limited capacity to read body language, and for physical examination. Most participants hoped to incorporate telehealth into their future health‐care routines.

Discussion and conclusion

Personal risk assessment and trust in health‐care professionals are determinants of the mode through which people with MS accessed health care during the COVID‐19 pandemic. Telehealth has been a valuable tool to mitigate COVID‐19 transmission through enabling contact‐free consultations. People with MS may find specific value in video consultations, which enable visualization of physical function. There is a need for training and support for all clinicians to conduct remote consultations.

Patient or public contribution

This study was conducted by a team comprised of four people with MS, a neurologist and four health services researchers.

'Traversing difficult terrain'. Advance care planning in residential aged care through multidisciplinary case conferences: A qualitative interview study exploring the experiences of families, staff and health professionals

BACKGROUND

Advance care planning improves the quality of end-of-life care for older persons in residential aged care; however, its uptake is low. Case conferencing facilitates advance care planning.

AIM

To explore the experience of participating in advance care planning discussions facilitated through multidisciplinary case conferences from the perspectives of families, staff and health professionals.

DESIGN

A qualitative study (February-July 2019) using semi-structured interviews.

SETTING

Two residential aged care facilities in one Australian rural town.

PARTICIPANTS

Fifteen informants [family (n = 4), staff (n = 5), health professionals (n = 6)] who had participated in advance care planning discussions facilitated through multidisciplinary case conferences.

RESULTS

Advance care planning was like navigating an emotional landscape while facing the looming loss of a loved one. This emotional burden was exacerbated for substitute decision-makers, but made easier if the resident had capacity to be involved or had previously made their wishes clearly known. The 'conversation' was not a simple task, and required preparation time. Multidisciplinary case conferences facilitated informed decision-making and shared responsibility. Opportunity to consider all care options provided families with clarity, control and a sense of comfort. This enabled multiple stakeholders to bond and connect around the resident.

CONCLUSION

While advance care planning is an important element of high quality care it involves significant emotional labour and burden for families, care staff and health professionals. It is not a simple administrative task to be completed, but a process that requires time and space for reflection and consensus-building to support well-considered decisions. Multidisciplinary case conferences support this process.
