Abstract
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are characterized by cytoplasmic deposition of the nuclear TAR-binding protein 43 (TDP-43). Although cytoplasmic re-localization of TDP-43 is a key event in the pathogenesis of ALS/FTD, the underlying mechanisms remain unknown. Here, we identified a non-canonical interaction between 14-3-3θ and TDP-43, which regulates nuclear-cytoplasmic shuttling. Neuronal 14-3-3θ levels were increased in sporadic ALS and FTD with TDP-43 pathology. Pathogenic TDP-43 showed increased interaction with 14-3-3θ, resulting in cytoplasmic accumulation, insolubility, phosphorylation, and fragmentation of TDP-43, resembling pathological changes in disease. Harnessing this increased affinity of 14-3-3θ for pathogenic TDP-43, we devised a gene therapy vector targeting TDP-43 pathology, which mitigated functional deficits and neurodegeneration in different ALS/FTD mouse models expressing mutant or non-mutant TDP-43, including when already symptomatic at the time of treatment. Our study identified 14-3-3θ as a mediator of cytoplasmic TDP-43 localization with implications for ALS/FTD pathogenesis and therapy.

Abstract
BACKGROUND Abrocitinib improved signs and symptoms of moderate-to-severe atopic dermatitis (AD) at Weeks 12 and 16 in phase 3 studies, with a manageable safety profile. Patient-reported outcomes with long-term abrocitinib treatment were not reported. OBJECTIVE To evaluate patient-reported outcomes with long-term abrocitinib treatment in patients with moderate-to-severe AD. METHODS JADE EXTEND (NCT03422822) is an ongoing, phase 3, long-term extension study that enrolled patients from previous abrocitinib AD trials. This analysis includes patients from the phase 3 trials JADE MONO-1 (NCT03349060), JADE MONO-2 (NCT03575871) and JADE COMPARE (NCT03720470) who completed the full treatment period of placebo or abrocitinib (200 or 100 mg once daily) and subsequently entered JADE EXTEND and were randomised to receive once-daily abrocitinib 200 or 100 mg. Patient-reported endpoints to Week 48 included the proportion of patients who achieved Dermatology Life Quality Index (DLQI) scores of 0/1 (no effect of AD on quality of life [QoL]) and a ≥4-point improvement in Patient-Oriented Eczema Measure (POEM) score (clinically meaningful improvement). Data cut-off: April 22, 2020. RESULTS Baseline DLQI mean scores were 15.4 and 15.3 in the abrocitinib 200- and 100-mg groups, respectively, which corresponded to a 'very large effect' on QoL; at Week 48, mean DLQI scores were lower with abrocitinib 200 mg (4.6; 'small effect' on QoL) and abrocitinib 100 mg (5.9; 'moderate effect' on QoL). Baseline POEM mean scores were 20.4 and 20.5 in the abrocitinib 200- and 100-mg groups, respectively; at Week 48, mean POEM scores were 8.2 and 11.0. Week 48 patient-reported responses with abrocitinib 200 mg and abrocitinib 100 mg were 44% and 34% for DLQI 0/1, and 90% and 77% for a ≥4-point reduction in POEM score. CONCLUSION In patients with moderate-to-severe AD, long-term abrocitinib treatment resulted in clinically meaningful improvement in patient-reported symptoms of AD, including QoL.

Abstract
OBJECTIVE To examine prevalence of novel newborn types among 541 285 live births in 23 countries from 2000 to 2021. DESIGN Descriptive multi-country secondary data analysis. SETTING Subnational, population-based birth cohort studies (n = 45) in 23 low- and middle-income countries (LMICs) spanning 2000-2021. POPULATION Liveborn infants. METHODS Subnational, population-based studies with high-quality birth outcome data from LMICs were invited to join the Vulnerable Newborn Measurement Collaboration. We defined distinct newborn types using gestational age (preterm [PT], term [T]), birthweight for gestational age using INTERGROWTH-21st standards (small for gestational age [SGA], appropriate for gestational age [AGA] or large for gestational age [LGA]), and birthweight (low birthweight, LBW [<2500 g], nonLBW) as ten types (using all three outcomes), six types (by excluding the birthweight categorisation), and four types (by collapsing the AGA and LGA categories). We defined small types as those with at least one classification of LBW, PT or SGA. We presented study characteristics, participant characteristics, data missingness, and prevalence of newborn types by region and study. RESULTS Among 541 285 live births, 476 939 (88.1%) had non-missing and plausible values for gestational age, birthweight and sex required to construct the newborn types. The median prevalences of ten types across studies were T+AGA+nonLBW (58.0%), T+LGA+nonLBW (3.3%), T+AGA+LBW (0.5%), T+SGA+nonLBW (14.2%), T+SGA+LBW (7.1%), PT+LGA+nonLBW (1.6%), PT+LGA+LBW (0.2%), PT+AGA+nonLBW (3.7%), PT+AGA+LBW (3.6%) and PT+SGA+LBW (1.0%). The median prevalence of small types (six types, 37.6%) varied across studies and within regions and was higher in Southern Asia (52.4%) than in Sub-Saharan Africa (34.9%). CONCLUSIONS Further investigation is needed to describe the mortality risks associated with newborn types and understand the implications of this framework for local targeting of interventions to prevent adverse pregnancy outcomes in LMICs.

Abstract
AIMS Amyotrophic lateral sclerosis (ALS) is characterised by a progressive loss of upper and lower motor neurons leading to muscle weakness and eventually death. Frontotemporal dementia (FTD) presents clinically with significant behavioural decline. Approximately 10% of cases have a known family history, and disease-linked mutations in multiple genes have been identified in FTD and ALS. More recently, ALS and FTD-linked variants have been identified in the CCNF gene, which accounts for an estimated 0.6% to over 3% of familial ALS cases. METHODS In this study, we developed the first mouse models expressing either wild-type (WT) human CCNF or its mutant pathogenic variant S621G to recapitulate key clinical and neuropathological features of ALS and FTD linked to CCNF disease variants. We expressed human CCNF WT or CCNFS621G throughout the murine brain by intracranial delivery of adeno-associated virus (AAV) to achieve widespread delivery via somatic brain transgenesis. RESULTS These mice developed behavioural abnormalities, similar to the clinical symptoms of FTD patients, as early as 3 months of age, including hyperactivity and disinhibition, which progressively deteriorated to include memory deficits by 8 months of age. Brains of mutant CCNF_S621G mice displayed an accumulation of ubiquitinated proteins with elevated levels of phosphorylated TDP-43 present in both CCNF_WT and mutant CCNF_S621G mice. We also investigated the effects of CCNF expression on interaction targets of CCNF and found elevated levels of insoluble splicing factor proline and glutamine-rich (SFPQ). Furthermore, cytoplasmic TDP-43 inclusions were found in both CCNF_WT and mutant CCNF_S621G mice, recapitulating the key hallmark of FTD/ALS pathology. CONCLUSIONS In summary, CCNF expression in mice reproduces clinical presentations of ALS, including functional deficits and TDP-43 neuropathology with altered CCNF-mediated pathways contributing to the pathology observed.

Abstract
INTRODUCTION Arthroplasty procedures are commonly performed in the UK. Informed consent is required for each procedure. To obtain informed consent the patient and their surgeon should discuss the risks and benefits of the proposed operation. This discussion should include both regional and systemic complication rates. Regional complications of arthroplasty are generally well documented in the literature. Systemic medical complications are less well described. This lack of accurate data could make it difficult for the treating surgeon to obtain valid consent. The aim of this paper was to review and compare the literature regarding the rate of systemic medical complications after common arthroplasty procedures. METHODS A literature search was conducted using the PubMed, Cochrane Library and MEDLINE databases. Studies regarding the systemic medical complications and mortality rate of joint replacement were included. FINDINGS We found that systemic complications were more frequent than regional complications following arthroplasty. The systemic complication rates were: hip, 5.1%; knee, 6.9%; ankle, 3.0%; shoulder, 11.2%; elbow, 8.5%; and wrist, 0%. Mortality rates for arthroplasty procedures were: hip, 0.3%; knee, 0.2%; ankle, 0.3%; shoulder, 0.3%; elbow, 0.2%; and wrist, 0%. CONCLUSIONS The most common systemic medical complication following arthroplasty was venous thromboembolism. Preoperative comorbidity was the most important risk factor for both postoperative mortality and systemic medical complications following arthroplasty procedures. We recommend that to obtain informed consent the given rates of systemic medical complications of joint replacement should be discussed and documented.

Abstract
Introduction Despite advancements in modern locking plate technology, distal humerus fractures in the elderly remain difficult to treat. A subset of fractures in this osteoporotic bone includes multiple, shallow articular fragments that renders fixation unreliable, precluding early motion and acceptable functional outcomes. Arthroplasty, in the form of either Total Elbow Arthroplasty (TEA) or Distal Humeral Hemiarthroplasty (DHH) are alternative treatment options in this cohort and are being increasingly used. Methods This article reviews the use of TEA or DHH for acute distal humerus fracture, including patient selection, pre-operative planning, surgical approach, implant positioning, rehabilitation, outcomes and complications. Results Arthroplasties are being increasingly used for acute distal humerus fractures, however they introduce potential complications not seen with fixation. Due care must be employed to correct implant positioning which is a function of implant rotation, implant length and implant sizing. We describe a robust technique for epicondyle repair in DHH and unlinked TEA to avoid instability. Outcomes of DHH and TEA for acute distal humerus fracture are encouraging, however further long-term outcome and comparative data regarding arthroplasty is required. Conclusions Short to medium term outcomes demonstrate that both DHH and TEA are valuable options for selected patients, although attention to technique is required to minimise potential complications.

Abstract
In Alzheimer's disease (AD), where amyloid-β (Aβ) and tau deposits in the brain, hyperexcitation of neuronal networks is an underlying disease mechanism, but its cause remains unclear. Here, we used the Collaborative Cross (CC) forward genetics mouse platform to identify modifier genes of neuronal hyperexcitation. We found LAMP5 as a novel regulator of hyperexcitation in mice, critical for the survival of distinct interneuron populations. Interestingly, synaptic LAMP5 was lost in AD brains and LAMP5 interneurons degenerated in different AD mouse models. Genetic reduction of LAMP5 augmented functional deficits and neuronal network hypersynchronicity in both Aβ- and tau-driven AD mouse models. To this end, our work defines the first specific function of LAMP5 interneurons in neuronal network hyperexcitation in AD and dementia with tau pathology.

Abstract
SETTING: Healthcare workers (HCWs) are at an increased risk of TB worldwide. Individual knowledge and attitudes may influence HCW behaviour, and subsequently, TB risk. Indonesia has the second highest case-load globally. OBJECTIVE: To measure TB knowledge and attitudes among a subsection of HCWs in Yogyakarta, Indonesia, and to explore factors associated with knowledge. DESIGN: A cross-sectional study using an online survey targeting all HCW staff was conducted among HCWs from four pre-selected healthcare facilities in Yogyakarta. Descriptive analysis and a multivariable linear regression were undertaken. RESULTS: Of 792 HCWs, 290 (37%) completed the survey; 64% (n = 185) were medical staff, 33% (n = 95) reported previously being tested for active TB and 8% (n = 24) for latent TB. The mean knowledge score was 7.2/11 (SD 1.5): this was higher among medical staff and those with university education (average score increase: 0.53, 95% CI 0.15 to 0.90; and 0.38, 95% CI 0.01 to 0.74, respectively). Participants agreed that free access to TB screening (93%) and treatment (93%) should be available, and 57% of medical and 77% of non-medical staff would take preventive therapy if eligible. CONCLUSION: Participants had practical understanding of TB; however, gaps were identified in knowledge about TB disease progression and prevention. Prevention programmes were viewed positively. We suggest further TB education and engagement programmes for HCWs.

Abstract
Background A significant improvement in clinical signs was demonstrated with abrocitinib relative to placebo in adolescents with moderate‐to‐severe atopic dermatitis (AD) in three phase 3, randomized, double‐blinded, placebo‐controlled studies (JADE TEEN [ClinicalTrials.gov, NCT03796676], JADE MONO‐1 [NCT03349060] and JADE MONO‐2 [NCT03575871]). Objectives To evaluate the impact of abrocitinib on patient‐reported signs/symptoms, including sleep loss and quality of life among adolescents with moderate‐to‐severe AD. Methods JADE TEEN, JADE MONO‐1 and JADE MONO‐2 were conducted in the Asia‐Pacific region, Europe and North America and included patients aged 12–17 years with moderate‐to‐severe AD and inadequate response to ≥ 4 consecutive weeks of topical medication or treatment with systemic therapy for AD. Patients were randomly assigned (1 : 1 : 1, JADE TEEN; 2 : 2 : 1, JADE MONO‐1/‐2) to receive once‐daily oral abrocitinib (200 or 100 mg) or placebo for 12 weeks in combination with topical therapy (JADE TEEN) or as monotherapy (JADE MONO‐1/‐2). Data from adolescent patients in JADE MONO‐1/‐2 were pooled for these analyses. Results At week 12, more adolescents treated with abrocitinib (200 or 100 mg) vs. placebo achieved a ≥ 4‐point improvement from baseline in the Patient‐Oriented Eczema Measure in JADE TEEN (83.9% and 77.0% vs. 60.2%) and JADE MONO‐1/‐2 (83.0% and 69.4% vs. 43.5%) and a ≥ 6‐point improvement from baseline in the Children’s Dermatology Life Quality Index in JADE TEEN (73.8% and 67.5% vs. 56.5%) and JADE MONO‐1/‐2 (70.0% and 57.1% vs. 19.0%). Significant improvements in SCORing Atopic Dermatitis Visual Analog Scale for sleep loss scores were demonstrated with abrocitinib vs. placebo at weeks 2‐12 in JADE TEEN and JADE MONO‐1/‐2. Conclusions Patient‐reported signs/symptoms, including reduction of sleep loss and quality of life, were substantially improved with abrocitinib monotherapy or combination therapy relative to placebo in adolescents with moderate‐to‐severe AD.

Abstract
Abstract
Aim
Osteoporotic fractures are rising in incidence, costing the National Health Service up to £1.1 billion for hospital care. The implementation of the Best Practice Tariff (BPT) of fragility fractures in 2010 created a financial incentive to achieve standards of best practice. In June 2015, a dedicated hip fracture unit (HFU) was set up at Princess Royal Hospital (PRH). The aim of this study is (A) to assess changes in performance to the BPT after the introduction of a dedicated HFU, and (B) whether the performance of a HFU is affected by direct/indirect presentation to the HFU.
Method
The performance of Brighton and Sussex University Hospitals (BSUH) to BPT pre and post HFU was assessed by a retrospective review of BPT performance data between 2015 and 2016. 870 patients who were treated for NOFF at BSUH were reviewed to assess whether the performance of the HFU was impacted by patients presenting either directly (PRH) to the HFU or indirectly (presentation to Royal Sussex County Hospital). Appropriate statistical tests were used to analyse the significant differences between these outcome measures.
Results
The comparison between pre and post HFU showed there was a significant increase in the time between A&E admission to ward, theatre or orthogeriatric (OG) assessment (P < 0.001) in patients presenting indirectly to HFU compared to direct presentations.
Conclusions
Having a HFU is cost neutral, and advantages of HFU include focusing NOFF care which improves in patient care. BPT achievements could be improved by increasing the direct admission of NOFF to the HFU.

The abnormal mislocalisation and ubiquitinated protein aggregation of the TAR DNA binding protein 43 (TDP-43) within the cytoplasm of neurons and glia in the central nervous system (CNS) is a pathological hallmark of early-onset neurodegenerative disorders amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The pathomechanisms underlying abnormal mislocalisation and aggregation of TDP-43 remain unknown. However, there is a growing body of evidence implicating neuroinflammation and immune-mediated mechanisms in the pathogenesis of neurodegeneration. Importantly, most of the evidence for an active role of immunity and inflammation in the pathogenesis of ALS and FTD relates specifically to TDP-43, posing the question as to whether immune-mediated mechanisms could hold the key to understanding TDP-43’s underlying role in neurodegeneration in both diseases. Therefore, this review aims to piece together key lines of evidence for the specific association of TDP-43 with key immune and inflammatory pathways to explore the nature of this relationship and the implications for potential pathomechanisms underlying neurodegeneration in ALS and FTD.

Abstract
The COVID-19 pandemic and response measures, including lockdowns and the reorientation of health services, have disrupted essential health services for other diseases, including TB, HIV and malaria. For TB, reductions in case detection due to the COVID-19 pandemic are projected to result in increased TB transmission, morbidity and mortality. Active case-finding (ACF) for TB using community-based approaches is a potential strategy to offset reductions in TB detection by obviating the need for patients to seek care at a health facility. A number of approaches can be used to conduct TB ACF safely and screen designated target populations while managing the risks of SARS-CoV-2 transmission for staff, individuals and the community. We present a framework of options for and experience of adapting TB ACF services in response to the challenges of COVID-19 in our programme in Yogyakarta, Indonesia. Key changes have included revised prioritisation of target populations focusing on household contacts, reducing case-finding throughput, implementation of additional infection control measures and precautions, and integration of COVID-19 screening among those being screened for TB. Our approach could inform other programmes seeking to adapt TB ACF services to mitigate the negative impact of COVID-19 on TB case detection.

Abstract
Host cell lipids play a pivotal role in the pathogenesis of respiratory virus infection. However, a direct comparison of the lipidomic profile of influenza virus and rhinovirus infections is lacking. In this study, we first compared the lipid profile of influenza virus and rhinovirus infection in a bronchial epithelial cell line. Most lipid features were downregulated for both influenza virus and rhinovirus, especially for the sphingomyelin features. Pathway analysis showed that sphingolipid metabolism was the most perturbed pathway. Functional study showed that bacterial sphingomyelinase suppressed influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication, but promoted rhinovirus replication. These findings suggest that sphingomyelin pathway can be a potential target for antiviral therapy, but should be carefully evaluated as it has opposite effects on different respiratory viruses. Furthermore, the differential effect of sphingomyelinase on rhinovirus and influenza virus may explain the interference between rhinovirus and influenza virus infection.

Abstract
Background There is little evidence on techniques for management of peri-prosthetic infection (PJI) in the context of severe proximal femoral bone loss. Custom-made articulating spacers (CUMARS) utilising cemented femoral stems as spacers was described providing better bone support and longer survival compared to conventional articulating spacers. We retrospectively report our experience managing PJI by adaptation of this technique using long cemented femoral stems where bone loss precludes use of standard stems. Methods Patients undergoing 1st stage revision for infected primary and revision THA using a cemented long stem (> 205 mm) and standard all-polyethylene acetabulum between 2011 and 2018 were identified. After excluding other causes of revision (fractures or aseptic loosening), Twenty-one patients remained out of total 721 revisions. Medical records were assessed for demographics, initial microbiological and operative treatment, complications, eradication of infection and subsequent operations. 2nd stage revision was undertaken in the presence of pain or subsidence. Results Twenty-one patients underwent 1st stage revision with a cemented long femoral stem. Mean follow up was 3.9 years (range 1.7–7.2). Infection was eradicated in 15 (71.4%) patients. Two patients (9.5%) required repeat 1st stage and subsequently cleared their infection. Three patients (14.3%) had chronic infection and are on long term suppressive antibiotics. One patient (4.8%) was lost to follow up before 2 years. Complications occurred in seven patients (33%) during or after 1st stage revision. Where infection was cleared, 2nd stage revision was undertaken in 12 patients (76.5%) at average of 9 months post 1st stage. Five (23.8%) CUMARS constructs remained in-situ at an average of 3.8 years post-op (range 2.6–5.1). Conclusions Our technique can be used in the most taxing of reconstructive scenarios allowing mobility, local antibiotic delivery, maintenance of leg length and preserves bone and soft tissue, factors not afforded by alternative spacer options.

Abstract
INTRODUCTION The COVID-19 pandemic presented extraordinary challenges to the UK healthcare system. This study aimed to assess the impact of the COVID-19 lockdown on the epidemiology, treatment pathways and 30-day mortality rates of hip fractures. Outcomes of COVID-19 positive patients were compared against those who tested negative. METHODS An observational, retrospective, multicentre study was conducted across six hospitals in the South East of England. Data were retrieved from the National Hip Fracture Database and electronic medical records. Data was collected for the strictest UK lockdown period (period B=23 March 2020-11 May 2020), and the corresponding period in 2019 (period A). RESULTS A total of 386 patients were admitted during period A, whereas 381 were admitted during period B. Despite the suspension of the 'Best Practice Tariff' during period B, time to surgery, time to orthogeriatric assessment, and 30-day mortality were similar between period A and B. The length of inpatient stay was significantly shorter during period B (11.5 days vs 17.0 days, p<0.001). Comparison of COVID-19 positive and negative patients during period B demonstrated that a positive test was associated with a significantly higher rate of 30-day mortality (53.6% vs 6.7%), surgical delay >36h (46.4% vs 30.8%, p=0.049), and increased length of inpatient stay (15.8 vs 11.7 days, p=0.015). CONCLUSIONS The COVID-19 lockdown did not alter the epidemiology of hip fractures. A substantially higher mortality rate was observed among patients with a COVID-19 positive test. These findings should be taken into consideration by the healthcare policymakers while formulating contingency plans for a potential 'second wave'.

Abstract
PURPOSE Thirty-day mortality of patients with hip fracture is well researched and predictive; validated scoring tools have been developed (Nottingham Hip Fracture Score, NHFS). COVID-19 has significantly greater mortality in the elderly and comorbid patients which includes hip fracture patients. Non-operative treatment is not appropriate due to significantly higher mortality, and therefore, these patients are often exposed to COVID-19 in the peri-operative period. What is unclear is the effect of concomitant COVID-19 infection in these patients. METHODS A multicentre prospective study across ten sites in the United Kingdom (responsible for 7% of hip fracture patients per annum in the UK). Demographic and background information were collected by independent chart review. Data on surgical factors included American Society of Anesthesiologists (ASA) score, time to theatre, Nottingham Hip fracture score (NHFS) and classification of fracture were also collected between 1st March 2020 and 30th April 2020 with a matched cohort from the same period in 2019. RESULTS Actual and expected 30-day mortality was found to be significantly higher than expected for 2020 COVID-19 positive patients (RR 3.00 95% CI 1.57-5.75, p < 0.001), with 30 observed deaths compared against the 10 expected from NHFS risk stratification. CONCLUSION COVID-19 infection appears to be an independent risk factor for increased mortality in hip fracture patients. Whilst non-operative management of these fractures is not suggested due to the documented increased risks and mortality, this study provides evidence to the emerging literature of the severity of COVID-19 infection in surgical patients and the potential impact of COVID-19 on elective surgical patients in the peri-operative period.

Abstract
BACKGROUND In late 2019, a novel human coronavirus - severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) - emerged in Wuhan, China. This virus has caused a global pandemic involving more than 200 countries. SARS-CoV-2 is highly adapted to humans and readily transmits from person-to-person. AIM To investigate the infectivity of SARS-CoV-2 under various environmental and pH conditions. The efficacies of various laboratory virus inactivation methods and home disinfectants against SARS-CoV-2 were investigated. METHODS The residual virus in dried form or in solution was titrated on to Vero E6 cells on days 0, 1, 3, 5 and 7 after incubation at different temperatures. Viral viability was determined after treatment with various disinfectants and pH solutions at room temperature (20-25oC). FINDINGS SARS-CoV-2 was able to retain viability for 3-5 days in dried form or 7 days in solution at room temperature. SARS-CoV-2 could be detected under a wide range of pH conditions from pH 4 to pH 11 for several days, and for 1-2 days in stool at room temperature but lost 5 logs of infectivity. A variety of commonly used disinfectants and laboratory inactivation procedures were found to reduce viral viability effectively. CONCLUSION This study demonstrated the stability of SARS-CoV-2 on environmental surfaces, and raises the possibility of faecal-oral transmission. Commonly used fixatives, nucleic acid extraction methods and heat inactivation were found to reduce viral infectivity significantly, which could ensure hospital and laboratory safety during the SARS-CoV-2 pandemic.

Abstract
Amyotrophic lateral sclerosis is a rapidly progressing and fatal disease characterized by muscular atrophy due to loss of upper and lower motor neurons. Pathogenic mutations in the TARDBP gene encoding TAR DNA binding protein-43 (TDP-43) have been identified in familial amyotrophic lateral sclerosis. We have previously reported transgenic mice with neuronal expression of human TDP-43 carrying the pathogenic A315T mutation (iTDP-43A315T mice) using a tetracycline-controlled inducible promotor system. Constitutive expression of transgenic TDP-43A315T in the absence of doxycycline resulted in pronounced early-onset and progressive neurodegeneration, and motor and memory deficits. Here, delayed transgene expression of TDP-43A315T by oral doxycycline treatment of iTDP-43A315T mice from birth till weaning was analyzed. After doxycycline withdrawal, transgenic TDP-43A315T expression gradually increased and resulted in cytoplasmic TDP-43, widespread ubiquitination, and cortical and hippocampal atrophy. In addition, these mice developed motor and gait deficits with underlying muscle atrophy, similar to that observed in the constitutive iTDP-43A315T mice. Surprisingly, in contrast to the constitutive iTDP-43A315T mice, these mice did not develop astrogliosis. In summary, delayed activation coupled with gradual increase in TDP-43A315T expression in the central nervous system of mature mice resulted in progressive functional deficits with neuron and muscle loss, but in the absence of a glial response. This suggests that astrocytosis does not contribute to functional deficits and neuronal loss upon TDP-43A315T expression in mature mice.

Abstract
Enterovirus A71 (EV-A71) and coxsackievirus A16 (CV-A16) are the most common causes of hand, foot, and mouth disease. Severe EV-A71 and CV-A16 infections may be associated with life-threatening complications. However, the pathogenic mechanisms underlying these severe clinical and pathological features remain incompletely understood. Lipids are known to play critical roles in multiple stages of the virus replication cycle. The specific lipid profile induced upon virus infection is required for optimal virus replication. The perturbations in the host cell lipidomic profiles upon enterovirus infection have not been fully characterized. To this end, we performed ultra-high performance liquid chromatography–electrospray ionization–quadrupole–time of flight-mass spectrometry (UPLC-ESI-Q-TOF-MS)-based lipidomics to characterize the change in host lipidome upon EV-A71 and CV-A16 infections. Our results revealed that 47 lipids within 11 lipid classes were significantly perturbed after EV-A71 and CV-A16 infection. Four polyunsaturated fatty acids (PUFAs), namely, arachidonic acid (AA), docosahexaenoic acid (DHA), docosapentaenoic acid (DPA), and eicosapentaenoic acid (EPA), were consistently upregulated upon EV-A71 and CV-A16 infection. Importantly, exogenously supplying three of these four PUFAs, including AA, DHA, and EPA, in cell cultures significantly reduced EV-A71 and CV-A16 replication. Taken together, our results suggested that enteroviruses might specifically modulate the host lipid pathways for optimal virus replication. Excessive exogenous addition of lipids that disrupted this delicate homeostatic state could prevent efficient viral replication. Precise manipulation of the host lipid profile might be a potential host-targeting antiviral strategy for enterovirus infection.

Abstract
INTRODUCTION Surgical fixation of tibial plateau fractures has been shown to improve long-term functional outcomes, but a major complication is that of postoperative infection which can be deleterious to long-term outcomes. This study aims to assess the impact of common comorbidities on the risk of postoperative infection. METHOD A retrospective study of 210 consecutive operatively treated patients, treated at two Level 1 Trauma Centres over a 27-month period was performed. Records were analysed to assess the presence of the study factors; smoking, alcohol intake >13 units/week, diabetes, and BMI > 30. The impact of these factors on infection was assessed with univariate and multivariate analyses. RESULTS 175 patients were included in the study, 56.6% male with a mean age of 46.9 years (± 18.2 years). Excessive alcohol consumption of >13 units/week was the only significant risk factor for postoperative infection (p = 0.05) on multivariate analysis. CONCLUSION This study has identified excessive alcohol consumption as the only independent risk factor for postoperative infection in patients with all types of tibial plateau fracture treated with operative fixation. No relationship between smoking, diabetes nor obesity was found for postoperative infection.

Abstract
SETTING Daru Island, Western Province, Papua New Guinea (PNG). OBJECTIVE To describe the implementation of a screening programme for household contacts of tuberculosis (TB) cases residing on Daru Island. DESIGN This was a retrospective descriptive study evaluating two periods of implementation: introduction and expansion of a screening programme for household contacts of drug-resistant TB (DR-TB) cases (March 2016 to September 2017), and inclusion of drug-susceptible TB (DS-TB) cases with provision of preventive therapy for eligible contacts between October 2017 and March 2018. RESULTS In the first period, the contact screening programme was established and strengthened by increasing coverage over time. There was a large number of contacts (median 8) in each household, and a high uptake of screening. In the second period of evaluation, respectively 412 and 223 contacts of 42 DS-TB and 25 DR-TB index cases were screened. Overall, 156 (24.6%) contacts reported TB-related symptoms and 9 (1.4%) were diagnosed with active TB. All 9 commenced TB treatment: 5 had DS-TB and 4 had DR-TB. Of 82 child contacts of DS-TB cases eligible for preventive therapy, 57 (69.5%) commenced treatment and 45 completed treatment. CONCLUSION Community-based household contact screening and management was successfully implemented under programme conditions in this high burden TB and DR-TB setting in PNG.

Abstract
SETTING Bedaquiline (BDQ) was introduced in the multi-drug-resistant tuberculosis (MDR-TB) programme in Daru in remote Papua New Guinea in 2015, along with a core package of active drug-safety monitoring (aDSM). OBJECTIVE To assess interim results and safety of BDQ for the treatment of MDR-TB from 1 July 2015 to 31 December 2017. DESIGN A retrospective cohort analysis of routine programme data. RESULTS Of 277 MDR-TB patients, 77 (39%) received BDQ with a total of 8 serious adverse events including 5 (6.5%) deaths, of which 1 (1.3% QTcF prolongation, grade 3) was attributable to BDQ. Of 200 (61%) patients who did not receive BDQ, there were 17 (9%) deaths. Completeness of monitoring for the BDQ group was 90% for >5 electrocardiograms and 79% for ⩾2 cultures. In the interim result indicator analysis at month 6 in the BDQ and non-BDQ groups, there were respectively 0% and 1% lost to follow-up; 6.5% and 8.5% who died; 94% and 91% in care; and 92% and 96% with negative culture among those monitored. CONCLUSION Early experience in Daru shows BDQ is safe and feasible to implement with aDSM with good interim effectiveness supporting the rapid adoption and scale-up of the 2019 WHO MDR-TB treatment guidelines in the programme and in similar remote settings.

Abstract
SETTING Daru General Hospital, Daru Island, Papua New Guinea, where high rates of tuberculosis (TB) have been reported. Prompt diagnosis and effective treatment are needed for improving TB outcomes and to prevent nosocomial transmission. OBJECTIVE To assess the time to treatment initiation and the risk factors associated with delayed treatment for patients started on TB treatment at Daru General Hospital from January to September 2017. DESIGN This was a retrospective cohort study that entailed reviewing the records from treatment, admission, discharge and presumptive TB registers. RESULTS The study included 360 patients on TB treatment. The median time from presentation to treatment initiation was 7 days [IQR 3-11]. Treatment was started <7 days for 215 patients (60%); however, only 16.2% commenced treatment <2 days. Risk factors for delayed treatment were diagnosis of TB as an inpatient (OR 2.67, 95% CI 1.35-5.28, P = 0.005) and having drug-resistant TB (OR 2.65, 95% CI 1.5-4.68. P = 0.001). CONCLUSION A high proportion of TB patients commenced treatment <7 days. Inpatient status, DR-TB and lack of microbiological confirmation were associated with delays in treatment initiation. We recommend that programmes monitor the time from presentation to treatment initiation, and propose that a period of >3 days from presentation to treatment initiation be considered as delayed treatment initiation.

Abstract
SETTING A response to an outbreak of multidrug-resistant tuberculosis (MDR-TB) on Daru Island, South Fly District (SFD), Western Province, Papua New Guinea (PNG) was implemented by a national emergency response taskforce. OBJECTIVE To describe programmatic interventions for TB in SFD and evaluate characteristics of TB case notifications, drug resistance and treatment outcomes. DESIGN This was a retrospective cohort study based on routine programmatic data for all patients enrolled on TB treatment at Daru General Hospital from 2014 to 2017. RESULTS The response involved high-level political commitment, joint planning, resource mobilisation, community engagement and strengthening TB case detection and treatment. Of 1548 people enrolled on TB treatment, 1208 (78%) had drug-susceptible TB (DS-TB) and 333 (21.5%) had MDR-TB. There was an increase in MDR-TB as a proportion of all TB. Treatment success rates increased over the study period from 55% to 86% for DS-TB, and from 70% to 81% for MDR-TB from 2014 to 2015. The 2014 case notification rate for TB in SFD was 1031/100 000, decreasing to 736/100 000 in 2017. CONCLUSION The outbreak was stabilised through the response from the national and provincial governments and international partners. Additional interventions are needed to decrease the TB burden in Daru.

Abstract
The microtubule-associated protein tau undergoes aberrant modification resulting in insoluble brain deposits in various neurodegenerative diseases, including frontotemporal dementia (FTD), progressive supranuclear palsy, and corticobasal degeneration. Tau aggregates can form in different cell types of the central nervous system (CNS) but are most prevalent in neurons. We have previously recapitulated aspects of human FTD in mouse models by overexpressing mutant human tau in CNS neurons, including a P301S tau variant in TAU58/2 mice, characterized by early-onset and progressive behavioral deficits and FTD-like neuropathology. The molecular mechanisms underlying the functional deficits of TAU58/2 mice remain mostly elusive. Here, we employed functional genomics (i.e. RNAseq) to determine differentially expressed genes in young and aged TAU58/2 mice to identify alterations in cellular processes that may contribute to neuropathy. We identified genes in cortical brain samples differentially regulated between young and old TAU58/2 mice relative to nontransgenic littermates and by comparative analysis with a dataset of CNS cell type-specific genes expressed in nontransgenic mice. Most differentially-regulated genes had known or putative roles in neurons and included presynaptic and excitatory genes. Specifically, we observed changes in presynaptic factors, glutamatergic signaling, and protein scaffolding. Moreover, in the aged mice, expression levels of several genes whose expression was annotated to occur in other brain cell types were altered. Immunoblotting and immunostaining of brain samples from the TAU58/2 mice confirmed altered expression and localization of identified and network-linked proteins. Our results have revealed genes dysregulated by progressive tau accumulation in an FTD mouse model.

Abstract
Capnocytophaga canimorsus is a commonly detectable commensal in the oral flora of dogs and cats, found in 25.5% and 15%, respectively, by culture and 70% and 55%, respectively, by molecular methods [1]. Formerly known as dysgonic fermenter 2 (DF-2), it was first reported in 1976 as a Gram-negative bacillus causing septicaemia and meningitis following dog bites [2]. It causes a spectrum of clinical syndromes from wound infections to bacteraemia and meningitis, especially in those with hyposplenism and alcoholism. We report a case of C. canimorsus meningitis and bacteraemia, and give a review of the relevant literature.
