Abstract
Abstract
Aim
The optimum surgical intervention for elderly patients with lumbar spinal stenosis(LSS) and low-grade degenerative-spondylolisthesis(LGDS) has been extensively debated. We conducted a systematic review and meta-analysis of randomised-controlled-trials(RCTs) comparing the effectiveness of decompression-alone against gold-standard decompression-with-fusion(D+F) in elderly patients with LSS and LGDS.
Method
A systematic literature search was performed on published databases from inception to October-2021. English-language RCTs of elderly patients (mean age over-65) with LSS and LGDS, who had undergone DA or D+F were included. The quality and weight of evidence was assessed, and a meta-analysis performed.
Results
Seven RCTs (n=581; mean age:65.9 years; 59.9% female) were included. There was no difference in visual-analogue-scale(VAS) scores of back-pain(BP) or leg-pain(LP) at mean follow-up of 28.6 months between both DA and D+F groups (BP: mean-difference (MD)-0.22, 95%CI:-0.76–0.32; LP: MD:-0.26, 95%CI:-0.79–0.27). In addition, subgroup analysis of long-term follow-up (>3 years) showed lower VAS scores for BP and LP in patients who underwent DA (BP MD:-1.70, 95%CI:-2.8-(-0.60); LP MD:-1.00, 95%CI:-1.77-(-0.23)). No difference in disability, measured by Oswestry-Disability-Index(ODI) scores, was found between both groups (MD:0.50, 95%CI: -3.31–4.31). However, patients in DA group had less hospital complications and fewer adverse events (total-surgical-complications OR:0.57, 95%CI:0.36–0.90), despite a higher rate of post-operative DS (OR:8.63, 95%CI:3.35–22.26).
Conclusions
DA is not inferior to D+F in elderly patients with LSS and LGDS. DA has better pain outcomes at three-years follow-up and carries lower risk hospital-complications and fewer adverse-events. Surgeons should weigh these findings with increased risk of DS-progression.

Abstract
Abstract
Aim
The purpose of this study was to perform a systematic review of the effects of orthopaedic virtual reality simulators on surgical skills across randomised controlled trials.
Method
The authors searched PubMed, CINAHL, MEDLINE, AMED, Eric, Embase, Cochrane Central Register of Controlled Trials, TRIP database and grey literature from 1946 to November 2020. Inclusion criteria were all level one studies, specifically randomised controlled trials with orthopaedic training simulators in hip surgery and clear evaluation of skills attained after virtual reality simulation (VR) training. The primary outcome was the reported quantitative assessment of operative skills acquisition. The Jadad scale was used as a tool in order to appraise the methodological quality of the included trials. The data collected were not amenable for meta-analysis as they were too heterogenous and were analysed and presented using a narrative analysis and the Synthesis Without Meta-analysis (SWiM) reporting guideline.
Results
A total of 1095 articles were identified. Four level I studies, all randomised controlled trials, including 86 participants were eligible for the final analysis. There were significant differences in the types of simulators, training structure, validity types, performance scores and outcome measures described in each study. In three out of four studies (75%) the use of VR training simulators led to improved surgical skills acquisition compared to other traditional teaching methods.
Conclusions
Overall, this review showed that the use of VR simulation training is a potential tool that can enhance surgical skills acquisition in hip surgery procedures compared to traditional education methods.

Abstract
BackgroundThere is increasing recognition of the complementary role for real-world evidence (RWE) in health care and regulatory decision-making (1). However, careful analysis is required when drugs are compared using observational data to account for differences between treatment groups. Electronic medical records (EMR) are an important source of real-world data (RWD), but outcomes are often recorded incompletely.We emulated a target trial of adalimumab (ADA) versus tofacitinib (TOF) in patients with rheumatoid arthritis (RA) using the OPAL dataset to illustrate the application of methodologies to address the challenges of non-random treatment assignment and incomplete data. The OPAL dataset is derived from EMR of 112 community-based rheumatologists around Australia, where practitioners have discretion to prescribe whichever b/tsDMARD they consider most clinically appropriate.ObjectivesTo estimate the average treatment effect (ATE) of TOF compared to ADA at 3 and 9 months, defined as the difference in mean disease activity score (DAS28CRP), in patients with RA who are new users of a b/tsDMARD. This is equivalent to aiming to estimate the intention-to-treat effect in a randomised controlled trial.MethodsOPAL patients diagnosed with RA were included if they initiated ADA or TOF between 1 October 2015 and 1 April 2021, were new b/tsDMARD users (no prior recorded b/tsDMARD, at least 6 months of prior csDMARD treatment), and had at least 1 component of DAS28CRP recorded at baseline or during follow-up. Data were also extracted on baseline characteristics. Baseline characteristics were DAS28CRP, patient demographics, regional location, disease duration, prescriber characteristics (including gender, experience), prior recorded comorbidities, and prior and concomitant treatment with csDMARDs and oral corticosteroids.We used random forest multiple imputation to impute missing baseline and follow-up DAS28CRP components (2). Stable balancing weights (SBW) were then used to balance the treatment groups in terms of their baseline characteristics, including DAS28CRP (3). For each imputed dataset, the ATE at 3 months was estimated as the difference between the mean outcome in the two treatment groups after balancing (i.e. weighting) the sample, and then these estimates were averaged across the 10 imputed datasets. The ATE at 9 months was estimated similarly. The whole procedure was subsequently performed in 1000 bootstrap samples to estimate a 95% confidence interval (CI) for the ATEs using the percentile method (4).Results842 patients were identified including n=569 treated with ADA and n=273 treated with TOF. After applying the SBW, the maximum difference between the mean of each baseline characteristic in the ADA and TOF groups was less than 0.03% of the corresponding standard deviation in the whole sample, indicating reasonable balance was achieved in this complex dataset. After weighting, mean DAS28CRP reduced from 5.3 at baseline (both ADA and TOF groups) to 2.6 and 2.3 at 3 and 9 months for ADA, and 2.4 and 2.3 at 3 and 9 months for TOF.The estimated ATE was -0.22 (95% CI -0.36, -0.03; p=0.02) at 3 months, indicating a modest but significant reduction in disease activity for patients on TOF. The estimated ATE was -0.03 (95% CI -0.19, 0.1; p=0.56) at 9 months, indicating no difference between groups.ConclusionDAS28CRP was significantly lower at 3 months for patients treated with TOF compared to ADA. However, 3 months of treatment with either drug led to substantive average reductions in mean DAS28CRP, consistent with remission. There was no difference between drugs at 9 months. Future work will estimate a per-protocol effect.References[1]Arlett et al.

Abstract
BackgroundTofacitinib (TOF), a potent selective inhibitor of Janus kinase (JAK), is an approved treatment of psoriatic arthritis (PsA). In Australia, patients with active PsA despite six months of therapy with a pre-specified combination of csDMARDs are eligible to receive subsidised b/tsDMARDs. The clinician can prescribe the b/tsDMARD they deem to be the most clinically appropriate for the patient. Limited data exist to describe the real-world treatment patterns, characteristics and clinical outcomes of patients with PsA who receive TOF in the real-world setting.ObjectivesTo describe real-world treatment patterns and treatment persistence among patients with PsA treated with TOF in the Australian post-approval setting using the OPAL dataset.MethodsThe OPAL dataset is a collection of deidentified clinical data derived from the electronic medical records of 112 rheumatologists at 43 sites around Australia. Adult patients with a diagnosis of PsA who received at least one prescription of TOF, a tumour necrosis factor inhibitor (TNFi) or an interleukin 17 inhibitor (IL-17Ai) between May 2019 and Sept 2020 were eligible, with data up to Sept 2021 included in the analysis. Results were summarised descriptively. Treatment persistence was summarised using Kaplan-Meier methods.ResultsOf 16,692 patients with PsA identified in the OPAL dataset, 1,486 (TOF n=406, IL-17Ai n=416, and TNFi n=664) were eligible for inclusion in this study. At the time of treatment initiation, the mean (SD) age of TOF, IL-17Ai and TNFi treated patients was 55.56 (12.68), 52.65 (12.72) and 50.32 (14.57) years, respectively. 19.2% of patients receiving TOF were first line compared with 41.8% of IL-17Ai and 62.8% of TNFi treated patients. The mean (SD) time from symptom onset to treatment initiation was longest for patients receiving TOF in first line (153.29 (127.50) months) compared to first line IL-17Ai (116.83 (113.97) months) and TNFi treated patients (92.37 (89.01) months). Overall, 34.2% of TOF, 32.9% of IL-17Ai and 26.4% of TNFi treated patients initiated therapy without concomitant cDMARDs being recorded.Overall median persistence was 16.54 months (95% CI 13.84, 19.53) for TOF treated patients, 17.65 months (95% CI, 15.75, 19.56) for IL-17Ai treated patients and 17.16 months (95% CI 14.86, 20.48) for TNFi treated patients. As expected, persistence was generally longer in patients treated as first line (Figure 1) with patients receiving TOF observed to have slightly higher persistence in the first 15 months of treatment.Figure 1.Treatment persistence of patients receiving TOF, IL-17Ai and TNFi as first line therapy. Plot curtailed at 15 months as relatively few patients have information past this point. Where no stop date was recorded, censoring occurs at last recorded visitConclusionIn this analysis of a large Australian real-world dataset, TOF was more commonly utilised as a later line therapy for patients with PsA. Patients receiving TOF were observed to have slightly higher persistence within the first 15 months of starting first line therapy in this preliminary analysis.AcknowledgementsThe authors acknowledge the members of OPAL Rheumatology Ltd and their patients for providing clinical data for this study, and Software4Specialists Pty Ltd for providing the Audit4 platform.

Abstract
BackgroundThere are currently ten biologic and targeted synthetic (b/ts)DMARDs acting via five different modes of action (MOA) available for the treatment of psoriatic arthritis (PsA) in Australia. b/tsDMARDs are government-subsidised, and once the patient reaches the eligibility requirements, the clinician can prescribe the agent deemed most appropriate. Available agents include TNF inhibitors (TNFi, adalimumab, etanercept, infliximab, golimumab, certolizumab pegol), IL-17A inhibitors (IL-17Ai, secukinumab, ixekizumab), and IL-12/23 inhibitor (IL-12/23i, ustekinumab). Two new MOAs were recently added to the rheumatologist’s armamentarium: the first JAK inhibitor (JAKi, tofacitinib) was subsidized from May 2019 followed by upadacitinib from Oct 2021, and an IL-23 inhibitor (IL-23i, guselkumab) was subsidized from July 2021.ObjectivesThe aim of this analysis was to describe the changing patterns of b/tsDMARD use for the treatment of PsA in real-world practice in Australia.MethodsDeidentified clinical data were sourced from the OPAL dataset, which is collected in a custom-built electronic medical record during the routine consultation1. Data from patients >18 years with a physician diagnosis of PsA who were prescribed a b/tsDMARD between Jan-2007 and Sept-2021 were included in the analysis. The software program Tableau was used to display the data.ResultsAt Sept 2021, 6,150 (38% of the total) patients with PsA in the OPAL dataset were prescribed b/tsDMARDs. Of these patients, 3741 (61%) were currently prescribed a TNFi, 1503 (24%) an IL-17Ai, 556 (9%) a JAKi, 222 (4%) an IL-12/23i and 134 patients (2%) an IL-23i. Over time, the 1st line TNFi initiations have decreased from 79.5% in 2018 to 65.2% in 2021. Conversely, 1st line IL-17Ai initiations have increased from 14.4% in 2018 to 22.2% in 2021. In 2021, TNFi accounted for 53.4% of 2nd line initiations and 38.2% of 3rd line initiations. IL-17Ai accounted for 30.4% of 2nd and 37.0% of 3rd line initiations and JAKi accounted for 10.5% of 2nd line and 14.2% of 3rd line initiations. In the 3 months that IL-23i has been subsidised, this MOA was the most initiated agent for patients who had been treated with more than two prior b/tsDMARDs. In 2021, 52.1% of patients switching from a 1st line TNFi switched to an alternative TNFi, 33.3% switched to an IL-17Ai and 11.3% switched to a JAKi in 2nd line. Of those switching from a 1st line IL-17Ai, 59.6% initiated a TNFi, 21.2% switched to an alternative IL-17Ai and 11.5% switched to a JAKi.ConclusionThe patterns of b/tsDMARD utilisation for the treatment of PsA, when the choice of agent is at the discretion of the rheumatologist, remains dynamic and is evolving as new MOAs become available. TNFi remains the most prescribed b/tsDMARD for first line therapy. However an increase in first line use of alternative MOAs has been observed. TNFi cycling remains a commonly utilised real world treatment strategy but appears to be declining as new MOAs become available.References[1]Littlejohn GO, Tymms KE, Smith T, Griffiths HT.

Abstract
Wastewater surveillance has been widely used as a supplemental method to track the community infection levels of severe acute respiratory syndrome coronavirus 2. A gap exists in standardized reporting for fecal indicator concentrations, which can be used to calibrate the primary outcome concentrations from wastewater monitoring for use in epidemiological models. To address this, measurements of fecal indicator concentration among wastewater samples collected from sewers and treatment centers in four counties of Kentucky (N = 650) were examined. Results from the untransformed wastewater data over 4 months of sampling indicated that the fecal indicator concentration of human ribonuclease P (RNase P) ranged from 5.1 × 101 to 1.15 × 106 copies/ml, pepper mild mottle virus (PMMoV) ranged from 7.23 × 103 to 3.53 × 107 copies/ml, and cross-assembly phage (CrAssphage) ranged from 9.69 × 103 to 1.85 × 108 copies/ml. The results showed both regional and temporal variability. If fecal indicators are used as normalization factors, knowing the daily sewer system flow of the sample location may matter more than rainfall. RNase P, while it may be suitable as an internal amplification and sample adequacy control, has less utility than PMMoV and CrAssphage as a fecal indicator in wastewater samples when working at different sizes of catchment area. The choice of fecal indicator will impact the results of surveillance studies using this indicator to represent fecal load. Our results contribute broadly to an applicable standard normalization factor and assist in interpreting wastewater data in epidemiological modeling and monitoring.

Abstract
There is an urgent need for the development of new treatments against trypanosomatid parasites; the causative agents of some of the most debilitating diseases in the developing world. This work targets an interesting 6-5-6-6 fused carboline scaffold, accessing a range of substituted derivatives through stereospecific intramolecular Pictet-Spengler condensation. Modification of the cyclisation conditions allowed retention of the carbamate protecting group and gave insight into the reaction mechanism. Compounds' bioactivities were measured against T. brucei, T. cruzi, L. majorand HeLa cells. We have identified promising pan-trypanocidal lead compounds based on the core scaffold, and highlight key SAR trends which will be useful for the future development of these compounds as potent trypanocidal agents.

Abstract
BACKGROUND Although HIV antiretroviral treatment (ART) access and uptake have increased among racial/ethnic minority individuals, lower rates of ART adherence and viral suppression persist, especially among Black men who have sex with men (BMSM) compared with their White counterparts. SETTING Black men who have sex with men living with HIV (BMSM+) residing in Los Angeles County (N = 124) were recruited in-person (eg, clinic) and online (eg, social networking apps). METHODS Participants completed a cross-sectional survey measuring demographic characteristics, structural syndemics (poverty, criminal justice involvement, and housing instability), and psychosocial syndemics (mental health and substance use). A text message survey assessed missed doses of ART over the past week. Zero-inflated Poisson regression models were used to evaluate variables associated with the number of missed doses of ART. RESULTS On average, participants missed 1.30 doses of ART (SD = 2.09) and reported structural syndemics: poverty (56.1%), criminal justice involvement (36.6%), housing instability (26.3%), and psychosocial syndemics: childhood sexual abuse (51.8%), intimate partner violence (16.9%), depression (39%), and problem alcohol use (15.5%). After controlling for employment, age, education, and psychosocial syndemics, participants with a one-point increase in structural syndemic indicators were found to be 1.63 times more likely to have missed a dose of ART. CONCLUSIONS Structural syndemic were associated with ART nonadherence among BMSM+ after adjusting for demographic and psychosocial factors. HIV treatment interventions that incorporate financial incentives, legal support, and housing may help improve ART adherence among BMSM+. Findings suggest that key priorities to ending the HIV epidemic must include structural interventions that alleviate poverty, eliminate disproportionate policing and criminalization, and end homelessness.

Abstract
Abstract
Aim
Kinesiophobia, the fear of physical movement and activity related to injury vulnerability, has been linked to sub-optimal outcomes following total knee replacement (TKR). This systematic review has two aims: to define the relationship between kinesiophobia and functional outcomes, pain and range of motion following TKR, and to evaluate published treatments for kinesiophobia following TKR.
Method
A primary search was performed in March 2020. English-language studies recruiting adult primary TKR patients, using the Tampa Scale of Kinesiophobia (TSK) were included. Study quality was assessed using the Newcastle Ottawa Scale for cohort or case control studies, and the Cochrane Collaboration Risk of Bias tool for randomised controlled trials.
Results
All thirteen included papers (82 identified) showed adequately low risk of methodological bias. TSK1 (activity avoidance) correlated with WOMAC functional score at 12 months in three studies (r = 0.20 p < 0.05, R = 0.317 p = 0.001, and correlation coefficient 0.197 p = 0.005). TSK score significantly correlated with mean active range of motion (ROM) at six months (105.33 (SD = 12.34) vs 85.53 (SD = 14.77) p = 0.000) post-operation. Three post-operative interventions improved TSK score vs control following TKR: a home-based functional exercise programme (TSK -14.30 (SD = 0.80) vs -2.10 (SD = 0.80) p < 0.001)), an outpatient CBT programme (TSK 27.76 (SD = 4.56) vs 36.54 (SD = 3.58), and video-based psychological treatment (TSK 24 (SD = 5) vs 29 (SD = 5) p < 0.01).
Conclusions
Kinesiophobia negatively affects functional outcomes up until one year post-operatively, while active ROM is reduced up to six months post procedure. Post-operative functional and psychological interventions can improve kinesiophobia following TKR.

Abstract
Abstract
Objective
To report our outcomes in utilizing extracorporeal membrane oxygenation (ECMO) institution for cardiac arrest.
Method
Retrospective records of all patients that needed ECPR between January 2015 and July 2020 have been reviewed. Primary outcomes were survival to ECMO decannulation, hospital discharge and one year survival. Secondary outcomes were the need for ECMO re-cannulation and neurology outcome using Paediatric Cerebral Performance Category (PCPC).
Results
A total of 44 consecutive patients were identified. 75 % were post cardiac surgery (n = 33), mean time from arrest to initiation of ECMO was 39.5 mins +/- 17.7 mins. Mean highest lactate prior to ECMO was 12.9 +/- 4.4. 79.6 % of patients received central cannulation. 11.4 % of patients (n = 5) needed more than one run of ECMO. Mean hours on ECMO were 175.4 +/- 212.5 hours and mean PCPC score was 2.14 +/- 1.68. Mean ICU stay was 16.2 +/- 16.9 days and total hospital stay was 47 +/- 68.5 days. Overall Survival to ECMO weaning was 68.4 % (n = 13) vs 92 % (n = 23) in neonates and paediatric patients, respectively. Survival to hospital discharge was 47.4 % (n = 9) vs 72 % (n = 18) and one year survival was 42.1 % (n = 8) vs 72 % (n = 18) in the neonatal and paediatric cohort, respectively.
Conclusions
Our survival rates are encouraging and in line with current published literature and comparable favourably to International ELSO (Extracorporeal life support organisation) registry for neonates and paediatric patients of all cause ECPR. Paediatric patients showed a survival advantage over neonates after ECPR.

Abstract
Abstract
Background
Alcohol has been associated with 10-35% trauma admissions and 40% trauma-related deaths globally. In response to the Covid-19 pandemic, the United Kingdom (UK) entered a state of ‘lockdown’ on 23rd March 2020. Restrictions were most significantly eased on 1st June 2020, when shops and schools re-opened. The purpose of this study was to quantify the effect of lockdown on alcohol-related trauma admissions.
Method
All adult patients admitted as ‘trauma calls’ to a London Major Trauma Centre (MTC) during April 2018 and April 2019 (pre-lockdown; N = 316), and 1st April – 31st May 2020 (lockdown; N = 191) had electronic patient records analysed. Patients’ blood alcohol level and records of intoxication were used to identify alcohol-related trauma. Trauma admissions from pre- and post-lockdown cohorts were compared using multiple regression analyses.
Results
Alcohol-related trauma was present in a significantly higher proportion of adult trauma calls during lockdown (lockdown 60/191 (31.4%), versus pre-lockdown 62/316 (19.6%); (Odds Ratio (OR) 0.83, 95% CI 0.38 to 1.28, p < 0.001). Lockdown was also associated with increased weekend admissions of trauma (lockdown 125/191 weekend (65.5%) vs pre-lockdown 179/316 (56.7%); OR -0.40, 95% CI -0.79 to -0.02, p = 0.041). No significant difference existed in the age, gender, or mechanism between pre-lockdown and lockdown cohorts (p > 0.05).
Conclusions
UK lockdown was independently associated with an increased proportion of alcohol-related trauma. Trauma admissions were increased during the weekend when staffing levels are reduced. With the possibility of subsequent global ‘waves’ of Covid-19, the risk of long-term repercussions of dangerous alcohol-related behaviour to public health must be addressed.

Abstract
Background and Objectives To determine optic nerve and retinal damage in aquaporin-4 antibody (AQP4-IgG)-seropositive neuromyelitis optica spectrum disorders (NMOSD) in a large international cohort after previous studies have been limited by small and heterogeneous cohorts. Methods The cross-sectional Collaborative Retrospective Study on retinal optical coherence tomography (OCT) in neuromyelitis optica collected retrospective data from 22 centers. Of 653 screened participants, we included 283 AQP4-IgG–seropositive patients with NMOSD and 72 healthy controls (HCs). Participants underwent OCT with central reading including quality control and intraretinal segmentation. The primary outcome was thickness of combined ganglion cell and inner plexiform (GCIP) layer; secondary outcomes were thickness of peripapillary retinal nerve fiber layer (pRNFL) and visual acuity (VA). Results Eyes with ON (NMOSD-ON, N = 260) or without ON (NMOSD-NON, N = 241) were assessed compared with HCs (N = 136). In NMOSD-ON, GCIP layer (57.4 ± 12.2 μm) was reduced compared with HC (GCIP layer: 81.4 ± 5.7 μm, p < 0.001). GCIP layer loss (−22.7 μm) after the first ON was higher than after the next (−3.5 μm) and subsequent episodes. pRNFL observations were similar. NMOSD-NON exhibited reduced GCIP layer but not pRNFL compared with HC. VA was greatly reduced in NMOSD-ON compared with HC eyes, but did not differ between NMOSD-NON and HC. Discussion Our results emphasize that attack prevention is key to avoid severe neuroaxonal damage and vision loss caused by ON in NMOSD. Therapies ameliorating attack-related damage, especially during a first attack, are an unmet clinical need. Mild signs of neuroaxonal changes without apparent vision loss in ON-unaffected eyes might be solely due to contralateral ON attacks and do not suggest clinically relevant progression but need further investigation.

Abstract
The Upper Indus Basin (UIB), which covers a wide range of climatic and topographic settings, provides an ideal venue to explore the relationship between climate and topography. While the distribution of snow and glaciers is spatially and temporally heterogeneous, there exist regions with similar elevation-snow relationships. In this work, we construct elevation-binned snow-cover statistics to analyze 3415 watersheds and 7357 glaciers in the UIB region. We group both glaciers and watersheds using a hierarchical clustering approach and find that (1) watershed clusters mirror large-scale moisture transport patterns and (2) are highly dependent on median watershed elevation. (3) Glacier clusters are spatially heterogeneous and are less strongly controlled by elevation, but rather by local topographic parameters that modify solar insolation. Our clustering approach allows us to clearly define self-similar snow-topographic regions. Eastern watersheds in the UIB show a steep snow cover-elevation relationship whereas watersheds in the central and western UIB have moderately sloped relationships, but cluster in distinct groups. We highlight this snow-cover-topographic transition zone and argue that these watersheds have different hydrologic responses than other regions. Our hierarchical clustering approach provides a potential new framework to use in defining climatic zones in the cyrosphere based on empirical data.

Abstract
Recent studies have characterized a dominant clone (Clone 1) of Mycobacterium abscessus subspecies massiliense (M. massiliense) associated with high prevalence in cystic fibrosis (CF) patients, pulmonary outbreaks in the United States (US) and United Kingdom (UK), and a Brazilian epidemic of skin infections. The prevalence of Clone 1 in non-CF patients in the US and the relationship of sporadic US isolates to outbreak clones are not known. We surveyed a reference US Mycobacteria Laboratory and a US biorepository of CF-associated Mycobacteria isolates for Clone 1. We then compared genomic variation and antimicrobial resistance (AMR) mutations between sporadic non-CF, CF, and outbreak Clone 1 isolates. Among reference lab samples, 57/147 (39%) of patients with M. massiliense had Clone 1, including pulmonary and extrapulmonary infections, compared to 11/64 (17%) in the CF isolate biorepository. Core and pan genome analyses revealed that outbreak isolates had similar numbers of single nucleotide polymorphisms (SNPs) and accessory genes as sporadic US Clone 1 isolates. However, pulmonary outbreak isolates were more likely to have AMR mutations compared to sporadic isolates. Clone 1 isolates are present among non-CF and CF patients across the US, but additional studies will be needed to resolve potential routes of transmission and spread.

Abstract
AIMS Chronic loneliness is experienced by around a third of parents, but there is no comprehensive review into how, why and which parents experience loneliness. This scoping review aimed to provide insight into what is already known about parental loneliness and give directions for further applied and methodological research. METHODS Searches for peer-reviewed articles were undertaken in six databases: PsycINFO, Medline, CINAHL, Embase, Web of Science and Scopus, during May 2019 to February 2020. We searched for English studies which examined loneliness experienced during parenthood, including studies that involved parents with children under 16 years and living at home and excluding studies on pregnancy, childbirth or postbirth hospital care. RESULTS From 2566 studies retrieved, 133 were included for analysis. Most studies (n = 80) examined the experience of loneliness in specific groups of parents, for example, teenage parents, parents of a disabled child. Other studies examined theoretical issues (n = 6) or health and wellbeing impacts on parents (n = 16) and their offspring (n = 17). There were 14 intervention studies with parents that measured loneliness as an outcome. Insights indicate that parental loneliness may be different to loneliness experienced in other cohorts. There is evidence that parental loneliness has direct and intergenerational impacts on parent and child mental health. Some parents (e.g. with children with chronic illness or disability, immigrant or ethnic minority parents) also appear to be at increased risk of loneliness although evidence is not conclusive. CONCLUSION This work has identified key gaps with further international, comparative and conceptual research needed.

Abstract
Wastewater monitoring for virus infections within communities can complement conventional clinical surveillance. Currently, most SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) clinical testing is voluntary and inconsistently available, except for a few occupational and educational settings, and therefore likely underrepresents actual population prevalence. Randomized testing on a regular basis to estimate accurate population-level infection rates is prohibitively costly and is hampered by a range of limitations and barriers associated with participation in clinical research. In comparison, community-level fecal monitoring can be performed through wastewater surveillance to effectively surveil communities. However, epidemiologically defined protocols for wastewater sample site selection are lacking. Herein, we describe methods for developing a geographically resolved population-level wastewater sampling approach in Jefferson County, Kentucky, and present preliminary results. Utilizing this site selection protocol, samples (n = 237) were collected from 17 wastewater catchment areas, September 8 to October 30, 2020 from one to four times per week in each area and compared to concurrent clinical data aggregated to wastewater catchment areas and county level. SARS-CoV-2 RNA was consistently present in wastewater during the studied period, and varied by area. Data obtained using the site selection protocol showed variation in geographically resolved wastewater SARS-CoV-2 RNA concentration compared to clinical rates. These findings highlight the importance of neighborhood-equivalent spatial scales and provide a promising approach for viral epidemic surveillance, thus better guiding spatially targeted public health mitigation strategies.

Abstract
Background:Sleep disorders are more prevalent in patients with ankylosing spondylitis (AS) compared to the general population. Sleep disturbance in AS, in addition to pain and fatigue, can lead to impaired physical function and reduced quality of life.Objectives:The primary objective was to determine the prevalence of sleep disturbance in patients with AS in a real-world Australian cohort using the Insomnia Severity Index (ISI) and Multivariate Apnoea Prediction Index (MAPI). ISI score of ≥ 15 is considered clinical insomnia. MAPI values below 0.05 are suggestive of clinical apnoea.Methods:Routinely collected, de-identified clinical data were sourced from the OPAL dataset. Patients aged between 18 and 95 years with a diagnosis of AS and who had completed at least one ISI or MAPI questionnaire between Jan-2019 and Sept-2020 were included. ISI and MAPI questionnaires were emailed to patients using OPAL’s electronic patient reported outcome (ePRO) delivery method or completed in the clinic using a smart device and returned to the patient’s file using a QR code. Disease activity was assessed using BASDAI collected at the same time as the sleep questionnaires. Age, sex and duration of symptoms were used to propensity match patients in the Il-17ai and TNFi group in a 1:2 ratio.Results:495 of the 5,323 patients identified with AS completed a questionnaire and were included in the analysis (n=395 TNFi, n=48 Il-17ai (secukinumab), n=52 other therapies). 142 were included in the propensity score matched population (n = 94 TNFi, and n = 48 Il-17ai). In the overall population the mean (SD) age was 48.3 (13.6), 55.4% were males, the mean (SD) BMI was 30.1 (19.6) at the index date and 4.8% reported depression. 51.7% had an optimal disease control (BASDAI <4). The mean (SD) ISI score was 8.6 (6.2). 48.1% reported no clinical significant insomnia, 32.7% reported subthreshold insomnia, 16% reported clinical insomnia (moderate severity) and 3.2% reported clinical insomnia (severe). The mean (SD) MAPI score was 0.4 (0.3). 292 patients (59.0%) had low risk of clinical apnoea, 134 patients (27.1%) had high risk of clinical apnoea and 69 patients 13.9% had not completed the MAPI questionnaire. In the propensity scored matched population, the TNFi and Il-17ai groups had mean (SD) ISI scores of 9.1 (6.6) and 8.9 (5.9) at index, respectively (p = 0.83) and mean (SD) MAPI scores of 0.3 (0.2) and 0.4 (0.3) at index, respectively (p=0.046), however a higher percentage of overweight and obese patients were identified in the Il-17ai treatment group. Ordered logistic regression analysis of the relationship between demographics and ISI in the matched population found that patients with BASDAI ≥4 were seven times more likely to experience greater sleep disturbance (OR 7.29, 95%CI 2.37 to 22.46, p=0.001) than those with BASDAI <4.Conclusion:In this real-world AS cohort, poor disease control was associated with sleep disturbance, despite bDMARD therapy. Little difference was observed between TNFi and Il-17ai treatment. Screening for sleep disturbance and fatigue in routine clinical care may provide a more holistic view of the burden of this disease.Table 1.Patient characteristics and outcome scores in the propensity

Abstract
Background:The availability of biosimilars as non-proprietary versions of established biologic disease-modifying anti-rheumatic drugs (bDMARDs) is enabling greater access for patients with rheumatic diseases to effective medications at a lower cost. Since April 2017 both the originator and a biosimilar for etanercept (trade names Enbrel and Brenzys, respectively) have been available for use in Australia.Objectives:[1]To model effectiveness of etanercept originator or biosimilar in reducing Disease Activity Score 28-joint count C reactive protein (DAS28CRP) in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) treated with either drug as first-line bDMARD[2]To describe persistence on etanercept originator or biosimilar as first-line bDMARD in patients with RA, PsA or ASMethods:Clinical data were obtained from the Optimising Patient outcomes in Australian rheumatoLogy (OPAL) dataset, derived from electronic medical records. Eligible patients with RA, PsA or AS who initiated etanercept originator (n=856) or biosimilar (n=477) as first-line bDMARD between 1 April 2017 and 31 December 2020 were identified. Propensity score matching was performed to select patients on originator (n=230) or biosimilar (n=136) with similar characteristics in terms of diagnosis, disease duration, joint count, age, sex and concomitant medications. Data on clinical outcomes were recorded at 3 months after baseline, and then at 6-monthly intervals. Outcomes data that were missing at a recorded visit were imputed.Effectiveness of the originator, relative to the biosimilar, for reducing DAS28CRP over time was modelled in the matched population using linear mixed models with both random intercepts and slopes to allow for individual heterogeneity, and weighting of individuals by inverse probability of treatment weights to ensure comparability between treatment groups. Time was modelled as a combination of linear, quadratic and cubic continuous variables.Persistence on the originator or biosimilar was analysed using survival analysis (log-rank test).Results:Reduction in DAS28CRP was associated with both time and etanercept originator treatment (Table 1). The conditional R-squared for the model was 0.31. The average predicted DAS28CRP at baseline, 3 months, 6 months, 9 months and 12 months were 4.0 and 4.4, 3.1 and 3.4, 2.6 and 2.8, 2.3 and 2.6, and 2.2 and 2.4 for the originator and biosimilar, respectively, indicating a clinically meaningful effect of time for patients on either drug and an additional modest improvement for patients on the originator.Median time to 50% of patients stopping treatment was 25.5 months for the originator and 24.1 months for the biosimilar (p=0.53). An adverse event was the reason for discontinuing treatment in 33 patients (14.5%) on the originator and 18 patients (12.9%) on the biosimilar.Conclusion:Analysis using a large national real-world dataset showed treatment with either the etanercept originator or the biosimilar was associated with a reduction in DAS28CRP over time, with the originator being associated with a further modest reduction in DAS28CRP that was not clinically significant. Persistence on treatment was not different between the two drugs.Table 1.Respondent characteristics.Fixed EffectEstimate95% Confidence Intervalp-valueTime (linear)0.900.89, 0.911.5e-63Time (quadratic)1.011.00, 1.011.3e-33Time (cubic)1.001.00, 1.007.1e-23Originator0.910.86, 0.960.0013Acknowledgements:The authors acknowledge the members of OPAL Rheumatology Ltd and their patients for providing clinical data for this study, and Software4Specialists Pty Ltd for providing the Audit4 platform.Supported in part by a research grant from Investigator-Initiated Studies Program of Merck & Co Inc, Kenilworth, NJ, USA.

Abstract
Background:Registry studies and clinical trials are increasingly incorporating patient reported outcomes (PROs) to measure the full burden of disease and better measure the efficacy and value of medicines; however, the burden of paper-based surveys, time constraints, and privacy concerns impede the widespread use of PROs in routine clinical care.Objectives:To develop a simple and secure technological solution to incorporate validated PROs into routine clinical care for patients with rheumatic diseases, and to assess the patient response to functional assessment of chronic illness therapy fatigue (FACIT-F), patient health questionnaire-2 (PHQ-2), and healthcare resource utilization (HCRU) questionnaires delivered using this ePRO method.Methods:A novel ePRO questionnaire delivery system was developed by Software4Specialists in partnership with OPAL Rheumatology. Validated PRO questionnaires were sent from the patient’s electronic medical record (Audit4, Software4Specialists) and delivered to the patient’s email address at time intervals specified by the rheumatologist (defaults to quarterly) or completed in the clinic waiting room prior to the consultation using a tablet or the patient’s smart phone (in-practice). Completed questionnaires were encrypted and returned directly to the patient’s Audit4 electronic medical record held on the clinician’s server for review at the next clinical consultation. The link to the PRO questionnaire expired within 28 days if the questionnaire was not completed, and the questionnaires were automatically cancelled if 2 consecutive links expired. This technology was made available to up to 111 rheumatologists located in 42 clinics in 6 states/territories in Australia, and the use of this technology to furnish the clinical consultation was voluntary for clinicians and patients. Deidentified clinical data was extracted from the servers of participating rheumatologists and aggregated across all sites.1 Data collected between April 2016-Dec 2020 was analysed descriptively.Results:Between April 2016-Dec 2020, 99,505 FACIT-F, PHQ-2 and HCRU questionnaires have been delivered to 5,784 patients from 39 of 42 contributing clinics (93%). 85% of questionnaires were delivered via email and 15% in-practice. Overall, 85% of patients completed at least one questionnaire, and of all questionnaires sent, 73% were completed. These rates have remained consistent over time. The completion rates were higher when questionnaires were delivered to patients in-practice compared to email (96% vs 69%). Females were more likely to engage with the questionnaires than males (87% vs 81%), and older patients were slightly more likely to complete all questionnaires delivered. 69% of questionnaires sent via email were completed on the day they were delivered and 94% were completed within 7 days. The median (IQR) number of questionnaires completed per patient was 3 (1,7) and the median (IQR) time since the first questionnaire was completed was 13 months (5,26).Conclusion:The novel Audit4 ePRO delivery system is an effective tool for incorporating PROs into routine clinical care to capture data directly from the patient on the impact of their condition on their quality of life. The data generated provides a unique opportunity to understand the full burden of disease for patients in the real-world setting and the impact of interventions.References:[1]Littlejohn GO, Tymms KE, Smith T, Griffiths HT.

Abstract
Background:There are currently eleven biologic and targeted synthetic (b/ts)DMARDs acting via five different modes of action available for the treatment of RA in Australia. The cost of b/tsDMARDs is subsidized by government for patients that have active RA despite six months of combination csDMARD therapy. Once a patient is eligible, the clinician can prescribe the b/tsDMARD they deem to be the most clinically appropriate for the patient. In Oct 2015 the first JAK inhibitor (JAKi) became available in Australia (tofacitinib, TOF), baricitinib (BARI) became available in Sept 2018, and upadacitinib (UPA) in May 2020. Each of these oral tsDMARDs possess different selectivity profiles towards different members of the JAK family (JAK1–3 and Tyk2).Objectives:The aim of this analysis was to determine the patterns of JAKi cycling in real-world practice in Australia.Methods:Deidentified clinical data were sourced from the OPAL dataset, which is collected in a custom-built electronic medical record during the routine consultation1. Data from patients >18 years with RA who commenced a b/tsDMARD between Jan-2007 and Dec-2020 were included in the analysis. A visual analytics software program was used to display data on medication initiation and cessation dates, and reasons for stopping tsDMARDs, which is recorded in the medical record at the time of the decision.Results:At Dec 2020, 28% of the 52,190 patients with RA in the OPAL dataset were prescribed b/tsDMARDs. Of these patients, 3,850 (26.3%) were currently prescribed a JAKi with 51.4% receiving TOF, 29.2% BARI and 19.4% UPA. In 2020, JAKi initiations accounted for 48.8% of all initiations and 30.7% of 1st line initiations; an increase of 6.1% and 3.5% from 2019, respectively. The percentage of patients switching from a first line JAKi to a second line JAKi rather than an agent with another mode of action increased from 33.1% in 2019 to 42.6% in 2020. This is despite 26.2% in 2019 and 45.8% in 2020 of the patients switching to another JAKi citing lack of efficacy as the reason for JAKi discontinuation. In the period between May 2020, when a third JAKi (UPA) become available, and Dec 2020, the majority of patients switching from first line TOF or BARI to another JAKI switched to UPA (69.4% and 83.9%, respectively), whilst 30.6% of first line TOF patients switched to BARI (30.6%), and 16.1% of first line BARI patients switched to TOF in second line. The majority of patients switching from second line TOF or BARI to a third line JAKi switched to UPA (73% and 96%, respectively), with 27% of second line TOF patients switching to BARI and a very low number moving from second line BARI to TOF (4%). JAKi choice after a third line TOF or BARI was almost exclusively UPA (86.2% and 95.5%, respectively).Conclusion:There has been significant and sustained uptake of JAKi for the management of RA in Australia and JAKi cycling is increasingly common in routine clinical care. Clinical outcomes and persistence following JAKi cycling requires further investigation.References:[1]Littlejohn GO, Tymms KE, Smith T, Griffiths HT.
