RESUMEN
INTRODUCTION: Increases in computed tomography (CT) use may not always reflect clinical need or improve outcomes. This study aimed to demonstrate how population level data can be used to identify variations in care between patient groups, by analysing system-level changes in CT use around the diagnosis of new conditions. METHODS: Retrospective repeated cross-sectional observational study using West Australian linked administrative records, including 504,723 adults diagnosed with different conditions in 2006, 2012 and 2015. For 90 days pre/post diagnosis, CT use (any and 2+ scans), effective dose (mSv), lifetime attributable risk (LAR) of cancer incidence and mortality from CT, and costs were assessed. RESULTS: CT use increased from 209.4 per 1000 new diagnoses in 2006 to 258.0 in 2015; increases were observed for all conditions except neoplasms. Healthcare system costs increased for all conditions but neoplasms and mental disorders. Effective dose increased substantially for respiratory (+2.5 mSv, +23.1%, P < 0.001) and circulatory conditions (+2.1 mSv, +15.4%, P < 0.001). The LAR of cancer incidence and mortality from CT increased for endocrine (incidence +23.4%, mortality +18.0%) and respiratory disorders (+21.7%, +23.3%). Mortality LAR increased for circulatory (+12.1%) and nervous system (+11.0%) disorders. The LAR of cancer incidence and mortality reduced for musculoskeletal system disorders, despite an increase in repeated CT in this group. CONCLUSIONS: Use and costs increased for most conditions except neoplasms and mental and behavioural disorders. More strategic CT use may have occurred in musculoskeletal conditions, while use and radiation burden increased for respiratory, circulatory and nervous system conditions. Using this high-level approach we flag areas requiring deeper investigation into appropriateness and value of care.
RESUMEN
INTRODUCTION: Calcium channel blockers (CCB), a commonly prescribed antihypertensive (AHT) medicine, may be associated with increased risk of breast cancer. The proposed study aims to examine whether long-term CCB use is associated with the development of breast cancer and to characterise the dose-response nature of any identified association, to inform future hypertension management. METHODS AND ANALYSIS: The study will use data from 2 of Australia's largest cohort studies; the Australian Longitudinal Study on Women's Health, and the 45 and Up Study, combined with the Rotterdam Study. Eligible women will be those with diagnosed hypertension, no history of breast cancer and no prior CCB use at start of follow-up (2004-2009). Cumulative dose-duration exposure to CCB and other AHT medicines will be captured at the earliest date of: the outcome (a diagnosis of invasive breast cancer); a competing risk event (eg, bilateral mastectomy without a diagnosis of breast cancer, death prior to any diagnosis of breast cancer) or end of follow-up (censoring event). Fine and Gray competing risks regression will be used to assess the association between CCB use and development of breast cancer using a generalised propensity score to adjust for baseline covariates. Time-varying covariates related to interaction with health services will also be included in the model. Data will be harmonised across cohorts to achieve identical protocols and a two-step random effects individual patient-level meta-analysis will be used. ETHICS AND DISSEMINATION: Ethical approval was obtained from the following Human research Ethics Committees: Curtin University (ref No. HRE2022-0335), NSW Population and Health Services Research Ethics Committee (2022/ETH01392/2022.31), ACT Research Ethics and Governance Office approval under National Mutual Acceptance for multijurisdictional data linkage research (2022.STE.00208). Results of the proposed study will be published in high-impact journals and presented at key scientific meetings. TRIAL REGISTRATION NUMBER: NCT05972785.

A hospital-wide point prevalence study investigated frailty and pain in patients with a cancer-related admission. Modifiable factors associated with frailty in people with cancer were determined through logistic regression. Forty-eight patients (19%) with cancer-related admissions were 2.65 times more likely to be frail and 2.12 more likely to have moderate pain. Frailty and pain were highly prevalent among cancer-related admissions, reinforcing the need for frailty screening and importance of pain assessment for patients with cancer.

INTRODUCTION: Despite the challenges of providing burn care throughout the 2.5MKm2 jurisdiction of Western Australia, early intervention after injury remains a key premise of the multidisciplinary model of care applied by the State Adult Burn Unit (SABU) team. In particular, contemporary guidelines support the facilitation of early ambulation after lower limb burn and skin grafting. Thus, this study aimed to evaluate the association between the timing of ambulation after burn and surgery on quality of life (QoL) outcomes. METHODS: Data from 1707 lower limb burn patients aged ≥ 18, admitted to the SABU between February 2011- December 2019, were included. Self-reported QoL longitudinal outcomes were assessed using the Short Form 36 and Burn Specific Health Scale Brief. Three recovery trajectories were defined according to their QoL outcome responses, mapped out to one year. Early ambulation was defined as occurring within 48 h of acute burn or surgery, as per SABU routine practice. RESULTS: Early ambulation was shown to have a positive association to the higher QoL trajectory group (>75% of cohort), though not statistically significant for the Physical Component (PCS) and Mental health Component (MCS) summary scores of the SF36; however, ambulation pathway was associated with adjusted long-term BSHS-B QoL outcomes. The least favorable trajectory of long-term recovery of the physical aspects of QoL was seen in those with higher TBSA and complications and increasing age and comorbidities. In contrast, the mental health components of QoL were robust to all those factors, apart from pre-existing comorbidities. CONCLUSION: Early ambulation after lower limb burn, and surgery, was positively associated with early and long-term QoL outcomes. Recovery trajectory is strongly indicated by where the patient journey begins after early acute care. The optimal physical QoL recovery trajectory was shared by those who were younger with reduced TBSA; complications; and, comorbidities whereas the mental health QoL trajectories were only impacted by comorbidities.

INTRODUCTION: The study examined whether increased physical activity (PA) in nonmetropolitan cancer survivors was maintained 12 weeks following the PPARCS intervention. METHODS: PA outcomes were assessed using an accelerometer at baseline, end of the intervention, and at 24 weeks. Linear mixed models were used to examine between-group changes in PA outcomes. RESULTS: The increased moderate-to-vigorous PA (MVPA) following intervention was maintained with significantly higher MVPA in the intervention group at 24 weeks (vs. controls) compared to baseline nett change of 52.5 min/week (95% CI 11.0-94.0.4). CONCLUSIONS: Distance-based interventions using wearables and health coaching may produce MVPA maintenance amongst nonmetropolitan cancer survivors.

OBJECTIVE: We examined the impact of long-term mental health outcomes on healthcare services utilisation among childhood cancer survivors in Western Australia using linked hospitalisations and community-based mental healthcare records from 1987 to 2019. METHOD: The study cohort included 2977 childhood cancer survivors diagnosed with cancer at age < 18 years in Western Australia from 1982 to 2014 and a matched non-cancer control group of 24,994 individuals. Adjusted hazard ratios of recurrent events were estimated using the Andersen-Gill model. The cumulative burden of events over time was assessed using the method of mean cumulative count. The annual percentage change in events was estimated using the negative binomial regression model. RESULTS: The results showed higher community-based service contacts (rate/100 person-years: 30.2, 95% confidence interval = [29.7-30.7] vs 22.8, 95% confidence interval = [22.6-22.9]) and hospitalisations (rate/1000 person-years: 14.8, 95% confidence interval = [13.6-16.0] vs 12.7, 95% confidence interval = [12.3-13.1]) in childhood cancer survivors compared to the control group. Childhood cancer survivors had a significantly higher risk of any event (adjusted hazard ratio = 1.5, 95% confidence interval = [1.1-2.0]). The cumulative burden of events increased with time since diagnosis and across age groups. The annual percentage change for hospitalisations and service contacts significantly increased over time (p < 0.05). Substance abuse was the leading cause of hospitalisations, while mood/affective and anxiety disorders were common causes of service contacts. Risk factors associated with increased service events included cancer diagnosis at age < 5 years, leukaemia diagnosis, high socioeconomic deprivation, and an attained age of < 18 years. CONCLUSIONS: The elevated utilisation of healthcare services observed among childhood cancer survivors emphasises the need for periodic assessment of psychiatric disorders, particularly in high-risk survivors, to facilitate early management and optimise healthcare resources.

BACKGROUND: Physical activity (PA) is important for cancer survivors. Trials of remotely delivered interventions are needed to assist in reaching under-served non-metropolitan cancer survivors. The objective of this study was to ascertain whether wearable technology, coupled with health coaching was effective in increasing PA in breast and colorectal cancer survivors living in regional and remote areas in Australia. METHODS: Cancer survivors from 5 states were randomized to intervention and control arms. Intervention participants were given a Fitbit Charge 2TM and received up to 6 telephone health coaching sessions. Control participants received PA print materials. Accelerometer assessments at baseline and 12 weeks measured moderate-to-vigorous PA (MVPA), light PA, and sedentary behavior. RESULTS: Eighty-seven participants were recruited (ageâ¯=â¯63 ± 11 years; 74 (85%) female). There was a significant net improvement in MVPA of 49.8 min/week, favoring the intervention group (95% confidence interval (95%CI): 13.6-86.1, pâ¯=â¯0.007). There was also a net increase in MVPA bouts of 39.5 min/week (95%CI: 11.9-67.1, pâ¯=â¯0.005), favoring the intervention group. Both groups improved light PA and sedentary behavior, but there were no between-group differences. CONCLUSION: This is the first study to demonstrate that, when compared to standard practice (i.e., PA education), a wearable technology intervention coupled with distance-based health coaching, improves MVPA in non-metropolitan cancer survivors. The results display promise for the use of scalable interventions using smart wearable technology in conjunction with phone-based health coaching to foster increased PA in geographically disadvantaged cancer survivors.

BACKGROUND: We investigated differences in cumulative incidence of first distant recurrence (DR) following non-metastatic breast cancer over a time period when new adjuvant therapies became available in Australia. METHODS: We conducted a health record linkage study of females with localized (T1-3N0) or regional (T4 or N+) breast cancer in the New South Wales Cancer Registry in 2001 to 2002 and 2006 to 2007. We linked cancer registry records with administrative records from hospitals, dispensed medicines, radiotherapy services, and death registrations to estimate the 9-year cumulative incidence of DR and describe use of adjuvant treatment. RESULTS: The study included 13,170 women (2001-2002 n = 6,338, 2006-2007 n = 6,832). The 9-year cumulative incidence of DR was 3.6% [95% confidence interval (CI), 2.3%-4.9%] lower for 2006-2007 diagnoses (15.0%) than 2001-2002 (18.6%). Differences in the annual hazard of DR between cohorts were largest in year two. DR incidence declined for localized and regional disease. Decline was largest for ages <40 years (absolute difference, 14.4%; 95% CI, 8.3%-20.6%), whereas their use of adjuvant chemotherapy (2001-2002 49%, 2006-2007 75%) and HER2-targeted therapy (2001-2002 0%, 2006-2007 16%) increased. DR did not decline for ages ≥70 years (absolute difference, 0.9%; 95% CI, -3.6%-1.8%) who had low use of adjuvant chemotherapy and HER2-targeted therapy. CONCLUSIONS: This whole-of-population study suggests that DR incidence declined over time. Decline was largest for younger ages, coinciding with changes to adjuvant breast cancer therapy. IMPACT: Study findings support the need for trials addressing questions relevant to older people and cancer registry surveillance of DR to inform cancer control programs.

AIM: To assess population-level characteristics and post-metastasis survival of people with recurrent metastatic breast cancer (rMBC) during a period when new publicly-subsidised adjuvant and metastatic systemic therapies became available. METHODS: Record linkage study of females in NSW Cancer Registry (NSWCR) diagnosed with non-metastatic breast cancer (BC) in 2001-2002 (C1) and 2006-2007 (C2). We identified first rMBC from NSWCR, administrative hospital records, dispensed medicines and radiotherapy services (2001-2016). We used death registrations to estimate cumulative incidence of BC death. RESULTS: The analysis included 2267 women with rMBC (C1:1210, C2:1057). Compared to C1, C2 had access to adjuvant HER2-targeted therapy and were more likely to have received adjuvant chemotherapy (C1:38%, C2:47%) and aromatase inhibitors (C1:52%, C2:73%, of those dispensed endocrine therapy). Five-year probability of BC death was 65% (95%CI:62-68%) in C1 and 63% (95%CI:60-66%) in C2. Regional disease (T4 or N + ) at initial BC diagnosis (C1:62%, C2:68%), and age ≥ 70 years at first metastasis (C1:27%, C2:31%) were more common in C2 and had poorer prognosis. Five-year probability of BC death was lower in C2 than C1 for treatment-defined HER2-positive BC (C1:72% 95%CI:63-79%; C2:52% 95%CI 45-60%) and those dispensed chemotherapy alone (C1:76% 95%CI:69-82, C2:67% 95%CI:59-74%, p = 0.01), but not treatment-defined hormone receptor-positive HER2-negative BC (C1:60% 95%CI 56-63%, C2:64% 95%CI 60-68%). CONCLUSIONS: Despite less favourable prognostic characteristics in C2, BC-related survival following rMBC was similar between the two cohorts; and improved for women with HER2-positive tumours. These findings support the real-world benefits of newer treatments for rMBC.

OBJECTIVES: We investigated shear wave elastography (SWE), B mode US and power Doppler (PDUS) as imaging biomarkers for longitudinal follow-up in idiopathic inflammatory myopathy (IIM), with a particular focus on immune-mediated necrotizing myopathy (IMNM) and DM. METHODS: Participants had serial SWE, PDUS on the deltoid (D) and vastus lateralis (VL) muscles on four occasions at intervals of 3-6 months. Clinical assessments included manual muscle testing, and patient- and physician-reported outcome scales. RESULTS: Thirty-three participants were included: IMNM = 17, DM = 12, overlap myositis = 3, PM = 1. Twenty were in a prevalent clinic group, and 13 were recently treated cases in an incident group. Differential changes in SWS and US domains occurred with time in both the prevalent and incident groups. In the VL-prevalent subgroup, echogenicity increased over time (P = 0.040), while in the incident cases there was a trend for reduction to normal over time (P = 0.097) with treatment. Muscle bulk reduced in the D-prevalent subgroup over time (P = 0.096), suggesting atrophy. SWS also reduced in the VL-incident subgroup over time (P = 0.096), suggesting a trend towards improvement in muscle stiffness with treatment. CONCLUSION: SWE and US appear promising as imaging biomarkers for patient follow-up in IIM and indicate changes over time, especially with echogenicity, muscle bulk and SWS in the VL. Due to the limitations of the participant numbers, additional studies with a larger cohort are needed to help evaluate these US domains further and outline specific characteristics within the IIM subgroups.

OBJECTIVE: To examine the use of CT, emergency department (ED)-presentation and hospitalisation and in 12 months before and after a diagnosis of cancer. DESIGN: Population-based retrospective cohort study. SETTING: West Australian linked administrative records at individual level. PARTICIPANTS: 104 009 adults newly diagnosed with cancer in 2004-2014. MAIN OUTCOME MEASURES: CT use, ED presentations, hospitalisations. RESULTS: As compared with the rates in the 12th month before diagnosis, the rate of CT scans started to increase from 2 months before diagnosis with an increase in both ED presentations and hospitalisation from 1 month before the diagnosis. These rates peaked in the month of diagnosis for CT scans (477 (95% CI 471 to 482) per 1000 patients), and for hospitalisations (910 (95% CI 902 to 919) per 1000 patients), and the month prior to diagnosis for ED (181 (95% CI 178 to 184) per 1000 patients) then rapidly reduced after diagnosis but remained high for the next 12 months. While the patterns of the health services used were similar between 2004 and 2014, the rate of the health services used during after diagnosis was higher in 2014 versus 2004 except for CT use in patients with lymphohaematopoietic cancer with a significant reduction. CONCLUSION: Our results showed an increase in demand for health services from 2 months before diagnosis of cancer. Increasing use of health services during and post cancer diagnosis may warrant further investigation to identify factors driving this change.

BACKGROUND: Our previous strain-specific systematic review (SR) showed that Lactobacillus reuteri (LR) DSM 17938 reduces necrotizing enterocolitis (NEC), late-onset sepsis (LOS), and time to full feeds (TFF) in preterm infants. Considering progress in the field over the past 6 years, we aimed to update our SR. METHODS: SR of randomized controlled trials (RCTs) and non-RCTs was conducted. MEDLINE, Embase, Emcare, Cochrane CENTRAL, and gray literature were searched in June 2023. Primary outcomes were TFF, NEC stage ≥II, LOS, and all-cause mortality. Meta-analysis was performed using random-effects model. Certainty of evidence (CoE) was summarized using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) guidelines. Trial sequential analysis (TSA) was applied for outcome of NEC in RCTs. RESULTS: Twelve RCTs (n = 2284) and four non-RCTs (n = 1616) were included. Six RCTs and three non-RCTs were new. Meta-analysis of RCTs showed LR significantly reduced TFF (mean difference, -2.70 [95% CI, -4.90 to -1.31] days; P = 0.0001), NEC stage ≥II (risk ratio [RR], 0.57 [95% CI, 0.37-0.87]; P = 0.009; eight RCTs), and LOS (RR, 0.72 [95% CI, 0.54-0.97]; P = 0.03); but not mortality (RR, 0.76 [95% CI, 0.54-1.06]; P = 0.10). TSA showed diversity-adjusted required information size (DARIS) as 3624 for NEC. Overall CoE was "very low." Meta-analysis of non-RCTs showed LR reduced NEC (odds ratio, 0.34 [95% CI, 0.15-0.77]; P = 0.01) but not LOS. LR had no adverse effects. CONCLUSIONS: Very low CoE suggests that LR DSM 17938 may reduce NEC and LOS and shorten TFF in preterm infants. Additional RCTs are required to confirm our findings.

BACKGROUND: The long-term effects of childhood cancer are unclear in the Australian context. We examined hospitalization trends for physical diseases and estimated the associated inpatient care costs in all 5-year childhood cancer survivors (CCS) diagnosed in Western Australia (WA) from 1982 to 2014. METHODS: Hospitalization records for 2,938 CCS and 24,792 comparisons were extracted from 1987 to 2019 (median follow-up = 12 years, min = 1, max = 32). The adjusted hazard ratio (aHR) of hospitalization with 95% confidence intervals (CI) was estimated using the Andersen-Gill model for recurrent events. The cumulative burden of hospitalizations over time was assessed using the mean cumulative count method. The adjusted mean cost of hospitalization was estimated using the generalized linear models. RESULTS: We identified a higher risk of hospitalization for all-cause (aHR, 2.0; 95% CI, 1.8-2.2) physical disease in CCS than comparisons, with the highest risk for subsequent malignant neoplasms (aHR, 15.0; 95% CI, 11.3-19.8) and blood diseases (aHR, 6.9; 95% CI, 2.6-18.2). Characteristics associated with higher hospitalization rates included female gender, diagnosis with bone tumors, cancer diagnosis age between 5 and 9 years, multiple childhood cancer diagnoses, multiple comorbidities, higher deprivation, increased remoteness, and Indigenous status. The difference in the mean total hospitalization costs for any disease was significantly higher in survivors than comparisons (publicly funded $11,483 United States Dollar, P < 0.05). CONCLUSIONS: The CCS population faces a significantly higher risk of physical morbidity and higher cost of hospital-based care than the comparisons. IMPACT: Our study highlights the need for long-term follow-up healthcare services to prevent disease progression and mitigate the burden of physical morbidity on CCS and hospital services.

PURPOSE: Whilst computed tomography (CT) imaging has been a vital component of injury management, its increasing use has raised concern regarding ionising radiation exposure. This study aims to identify latent classes (underlying patterns) of CT use over a 3-year period following the incidence of injury and factors predicting the observed patterns. METHOD: A retrospective observational cohort study was conducted in 21,544 individuals aged 18 + years presenting to emergency departments (ED) of four tertiary public hospitals with new injury in Western Australia. Mixture modelling approach was used to identify latent classes of CT use over a 3-year period post injury. RESULTS: Amongst injured people with at least one CT scan, three latent classes of CT use were identified including a: temporarily high CT use (46.4%); consistently high CT use (2.6%); and low CT use class (51.1%). Being 65 + years or older, having 3 + comorbidities, history with 3 + hospitalisations and history of CT use before injury were associated with consistently high use of CT. Injury to the head, neck, thorax or abdomen, being admitted to hospital after the injury and arriving to ED by ambulance were predictors for the temporarily high use class. Living in areas of higher socio-economic disadvantage was a unique factor associated with the low CT use class. CONCLUSIONS: Instead of assuming a single pattern of CT use for all patients with injury, the advanced latent class modelling approach has provided more nuanced understanding of the underlying patterns of CT use that may be useful for developing targeted interventions.

OBJECTIVE: Dementia affects individuals older than 65 years. Currently, residential aged care facilities (RACF) use psychotropic medications to manage behavioural and neuropsychiatric symptoms of dementia (BPSD), which are recommended for short-term use and have substantial side effects, including increased mortality. Cannabinoid-based medicines (CBM) have some benefits that inhibit BPSD and cause minimal adverse effects (AEs), yet limited research has been considered with this population. The study aimed to determine a tolerable CBM dose (3:2 delta-9-tetrahydrocannabinol:cannabidiol), and assessed its effect on BPSD, quality of life (QoL) and perceived pain. METHODS: An 18-week randomised, double-blinded, crossover trial was conducted. Four surveys, collected on seven occasions, were used to measure changes in BPSD, QoL and pain. Qualitative data helped to understand attitudes towards CBM. General linear mixed models were used in the analysis, and the qualitative data were synthesised. RESULTS: Twenty-one participants (77% female participants, mean age 85) took part in the trial. No significant differences were seen between the placebo and CBM for behaviour, QOL or pain, except a decrease in agitation at the end of treatment in favour of CBM. The qualitative findings suggested improved relaxation and sleep among some individuals. Post hoc estimates on the data collected suggested that 50 cases would draw stronger conclusions on the Neuropsychiatric Inventory. CONCLUSIONS: The study design was robust, rigorous and informed by RACF. The medication appeared safe, with minimal AEs experienced with CBM. Further studies incorporating larger samples when considering CBM would allow researchers to investigate the sensitivity of detecting BPSD changes within the complexity of the disease and concomitant with medications.

Infant and Young Child Feeding (IYCF) breastfeeding guidelines of the World Health Organization (WHO) have been promoted in Nepal since the early 1990s. This study investigated whether antenatal and perinatal service delivery in Nepal are associated with early initiation of breastfeeding and age-appropriate feeding practice (exclusive breastfeeding to six months; introduction of complementary foods at six months with continued breastfeeding to two years). Data from the 2016 Nepal Demographic and Health Survey (NDHS) were analysed using multivariable logistic regression. The unit of analysis was an interviewed woman and her last-born child aged 0-23 months. We examined number of antenatal visits, place and type of delivery, infant-mother skin-to-skin contact post-delivery, and breastfeeding observation and counselling by a healthcare provider within two days post-delivery. Of 1938 mother-infant dyads, 1073 (55.4%) commenced breastfeeding within one hour of delivery and 1665 (85.9%) were engaged in age-appropriate feeding. Breastfeeding within one hour of delivery was associated with infants delivered vaginally (aOR: 4.76, 95% CI: 2.96-7.65), infant-mother skin-to-skin contact post-delivery (aOR:2.10, 95% CI: 1.63-2.72) and observation of breastfeeding by a healthcare provider within two days post-delivery (aOR: 1.58, 95% CI: 1.20-2.08). Age-appropriate feeding was lowest amongst mothers with infants aged 4-5 months (40.8%) compared to those with infants aged 0-1 month (aOR: 0.158, 95% CI: 0.083-0.302). Antenatal and perinatal service delivery were not significantly associated with age-appropriate feeding. Further promotion of infant-mother skin-to-skin contact post-delivery (including after caesarean delivery) and observation of early breastfeeding may increase the rate of breastfeeding within one hour of delivery. Promotion of exclusive breastfeeding in antenatal and perinatal services and additional postnatal support should be considered to increase exclusive breastfeeding of infants to six months. These improvements may be achieved through enhanced implementation of the Baby Friendly Hospitals Initiative and effective training and sufficient practice for skilled birth attendants.
RESUMEN
Frailty and pain in hospitalised patients are associated with adverse clinical outcomes. However, there is limited data on the associations between frailty and pain in this group of patients. Understanding the prevalence, distribution and interaction of frailty and pain in hospitals will help to determine the magnitude of this association and assist health care professionals to target interventions and develop resources to improve patient outcomes. This study reports the point prevalence concurrence of frailty and pain in adult patients in an acute hospital. A point prevalence, observational study of frailty and pain was conducted. All adult inpatients (excluding high dependency units) at an acute, private, 860-bed metropolitan hospital were eligible to participate. Frailty was assessed using the self-report modified Reported Edmonton Frail Scale. Current pain and worst pain in the last 24 h were self-reported using the standard 0-10 numeric rating scale. Pain scores were categorised by severity (none, mild, moderate, severe). Demographic and clinical information including admitting services (medical, mental health, rehabilitation, surgical) were collected. The STROBE checklist was followed. Data were collected from 251 participants (54.9% of eligible). The prevalence of frailty was 26.7%, prevalence of current pain was 68.1% and prevalence of pain in the last 24 h was 81.3%. After adjusting for age, sex, admitting service and pain severity, admitting services medical (AOR: 13.5 95% CI 5.7-32.8), mental health (AOR: 6.3, 95% CI 1. 9-20.9) and rehabilitation (AOR: 8.1, 95% CI 2.4-37.1) and moderate pain (AOR: 3.9, 95% CI 1. 6-9.8) were associated with increased frailty. The number of older patients identified in this study who were frail has implications for managing this group in a hospital setting. This indicates a need to focus on developing strategies including frailty assessment on admission, and the development of interventions to meet the care needs of these patients. The findings also highlight the need for increased pain assessment, particularly in those who are frail, for more effective pain management.Trial registration: The study was prospectively registered (ACTRN12620000904976; 14th September 2020).

BACKGROUND: Western Australia (WA) public health measures to eradicate SARS-CoV-2 resulted in a secondary reduction in paediatric respiratory syncytial virus (RSV) admissions. Following an absent expected 2020 winter peak, RSV-positive admissions surged during the summer of 2020. AIM: This report examines the number of RSV-positive admissions and severities across 36 months to better understand this out-of-season epidemic. METHODS: A retrospective observational study was performed assessing the number and severity of RSV-related respiratory hospitalisations at a peripheral paediatric centre from March 2018 to February 2021. Data were extracted from the hospital clinical database. RESULTS: The total number of included participants was n = 294. The total number of RSV hospitalisations in SY (study year) 2018 (March 2018 to February 2019), SY 2019 (March 2019 to February 2020) and SY 2020 (March 2020 to February 2021) was 67, 98 and 129, respectively. Prior to SARS-CoV-2, RSV hospitalisations were highest during the winter months. In SY 2020, there were 0 RSV hospitalisations during winter, while 101 admissions in the following summer season. The proportion of admissions requiring respiratory support was significantly reduced in SY 2020 (34.1%) compared to SY 2018 (46.9%, P = 0.050) and SY 2019 (55.2%, P = 0.004). The median length of stay (LOS) in 2020 was 2.0 which was significantly reduced from 2018 and 2019 which was 3.0, P = 0.001; and 3.0, P < 0.001, respectively. CONCLUSION: Following a period of RSV absence, there was an unprecedented surge in admission, however, with lower severity and shorter LOS.

INTRODUCTION: In patients with acute ischemic stroke, the location and volume of an irreversible infarct core determine prognosis and treatment. We aimed to determine if automated CT perfusion (CTP) is non-inferior to diffusion-weighted imaging (DWI) or fluid-attenuated inversion recovery (FLAIR) in predicting the acute infarct core. METHODS: In this systematic review and meta-analysis, we searched MEDLINE and EMBASE from 1960 to December 2020. Five outcome measures were examined: volumetric difference, volumetric correlation, sensitivity and specificity at the patient level, Dice coefficient, and sensitivity and specificity at the voxel level. A random-effects meta-analysis was performed for volumetric difference and correlation. RESULTS: From 3,986 studies retrieved, 48 studies met our inclusion criteria with 46 studies on anterior circulation, one study on posterior circulation, and one study on lacunar infarct strokes. In anterior circulation stroke, there were no significant mean volumetric differences between CTP and acute DWI (cerebral blood flow [CBF] 0.52 mL, 95% CI [-0.07, 1.11], I2 0.0%; relative CBF [rCBF] 3.01 mL, 95% CI [-0.46, 6.48], I2 82.6%; relative cerebral blood volume [rCBV] -12.84 mL, 95% CI [-38.56, 12.88], I2 96.2%) and between CTP and delayed DWI or FLAIR (rCBF -1.29 mL, 95% CI [-6.49, 3.92], I2 91.8%; rCBV -5.80 mL, 95% CI [-16.20, 4.60], I2 84.2%). Mean correlation between CTP and acute DWI was 0.90 (95% CI [0.80, 0.95], I2 60.0%) for rCBF and 0.84 (95% CI [0.58, 0.94], I2 93.5%) for rCBV. Mean correlation between CTP and delayed DWI or FLAIR was 0.74 (95% CI [0.57, 0.85], I2 94.6%) for rCBF and 0.90 (95% CI [0.69, 0.97], I2 93.1%) for rCBV. Sensitivity and specificity at the patient level were reported by three studies and Dice coefficient by four studies. Statistical analysis could not be performed for sensitivity and specificity at the voxel level. Limited evidence was available for posterior circulation or lacunar infarct strokes. CONCLUSION: Due to significant heterogeneity and insufficient high-quality studies reporting each outcome, there is insufficient evidence to reliably determine the accuracy of CTP prediction of the infarct core compared to DWI or FLAIR.
