Abstract
Inhibitor development is the most severe complication of hemophilia A care, and is associated with increased morbidity and mortality. The aim of this study was to use a novel IgG epitope mapping method to explore the factor VIII (FVIII)-specific epitope profile in the SIPPET cohort population and to develop an epitope-mapping based inhibitor prediction model. The population consisted of 122 previously untreated patients with severe hemophilia A that were followed-up for 50 days of exposure to FVIII or 3 years, whichever occurred first. Sampling was performed before FVIII treatment and at the end of the follow-up. The outcome was inhibitor development. The FVIII epitope repertoire was assessed by means of a novel random peptide phage-display assay. A LASSO regression model and a random forest model were fitted on post-treatment sample data and validated in pre-treatment sample data. The predictive performance of these models was assessed by the C-statistic and a calibration plot. We identified 27,775 peptides putatively directed against FVIII, which were used as input for the statistical models. The C-statistic of the LASSO and random forest models were good at 0.78 (95%CI: 0.69-0.86) and 0.80 (95%CI: 0.72-0.89). Model calibration of both models was moderately good. Two statistical models, developed on data from a novel random peptide phage display assay, were used to predict inhibitor development before exposure to exogenous FVIII. These models can be used to set up diagnostic tests that predict the risk of inhibitor development before starting treatment with FVIII.

Abstract
Emicizumab is approved for prophylaxis of patients with hemophilia A (HA). Despite its efficacy in reducing bleeding, a few patients on emicizumab still experience hemarthrosis, but no tool is yet available to identify those at higher risk of spontaneous joint bleeding. To evaluate whether laboratory measurements (global coagulation assays and emicizumab concentration) and/or arthropathy scores can distinguish patients at higher risk of spontaneous joint bleeding while on emicizumab prophylaxis. Thrombin generation assay (TGA) was assessed upon the addition of tissue factor and synthetic phospholipids. Non-activated thromboelastography (NATEM) was performed in citrated whole blood. Emicizumab concentrations were measured with a modified one-stage FVIII assay. The degree of hemophilic arthropathy was assessed with the Haemophilia Joint Health Score (HJHS) and Hemophilia Early Arthropathy Detection with Ultrasound score (HEAD-US). A Cox proportional hazards model was used to evaluate the association between variables and bleeding. The predictive power of these variables was investigated by ROC analysis. Forty HA patients with and without inhibitors on emicizumab prophylaxis were enrolled in an observational cohort study. Ten of 40 developed spontaneous joint bleeding. None of the lab parameters were able to distinguish patients at higher risk of spontaneous joint bleeding. ROC analysis showed that during emicizumab prophylaxis only the presence of synovitis and a higher HEAD-US score were associated with spontaneous joint bleeding (AUC 0.84). A greater degree of arthropathy and the presence of synovitis could help to predict the risk of spontaneous joint bleeding in HA patients on emicizumab prophylaxis.

Abstract
PURPOSE Electric scooters (e-scooters) are an increasingly popular method of transportation worldwide. However, there are concerns regarding their safety, specifically with regards to orthopaedic injuries. We aimed to investigate the overall burden and financial impact on orthopaedic services as a result of e-scooter-related orthopaedic injuries. METHODS We retrospectively identified all e-scooter-related injuries requiring orthopaedic admission or surgical intervention in a large District General Hospital in England over a 16-month period between September 2020 and December 2021. Injuries sustained, surgical management, inpatient stay and resources used were calculated. RESULTS Seventy-nine patients presented with orthopaedic injuries as a result of e-scooter transportation with a mean age of 30.1 years (SD 11.6), of which 62 were males and 17 were females. A total of 86 individual orthopaedic injuries were sustained, with fractures being the most common type of injury. Of these, 23 patients required 28 individual surgical procedures. The combined theatre and recovery time of these procedures was 5500 min, while isolated operating time was 2088 min. The total cost of theatre running time for these patients was estimated at £77,000. A total of 17 patients required hospital admission under Trauma and Orthopaedics, which accounted for total combined stay of 99 days with a mean length of stay of 5.8 days. CONCLUSION While there are potential environmental benefits to e-scooters, we demonstrate the risks of injury associated with their use and the associated increased burden to the healthcare system through additional emergency attendances, frequent outpatient clinic appointments, surgical procedures, and hospital inpatient admissions.

Abstract
Objectives Anti-factor VIII (FVIII) antibodies have been reported to exhibit both neutralizing and non-neutralizing characteristics. This is the first study investigating the full spectrum of FVIII-specific antibodies, including non-neutralizing antibodies, very-low titer inhibitors, and inhibitors, in a large nationwide population of persons with hemophilia A of all severities. Methods All persons with hemophilia A (mild (FVIII > 5-40 IU/dL)/moderate [FVIII 1-5 IU/dL)/severe (FVIII < 1 IU/dL)] with an available plasma sample who participated in the sixth Hemophilia in the Netherlands study between 2018 and 2019 were included. The presence of anti-FVIII antibodies of the immunoglobulin A, M, and G isotypes and IgG subclasses, along with antibody titer levels, were assessed using direct-binding ELISAs. FVIII specificity was assessed using a competition-based ELISA approach. The inhibitor status was determined using the Nijmegen ultra-sensitive Bethesda assay (NusBA) and the Nijmegen Bethesda assay (NBA). Results In total, 788 persons with hemophilia A (336 (42.6%) mild, 123 (15.6%) moderate, 329 (41.8%) severe hemophilia) were included. The median age was 45 years (IQR 24-60), and the majority (50.9%) had over 150 exposure days to FVIII concentrates. Within our population, 144 (18.3%) individuals had non-neutralizing FVIII-specific antibodies, 10 (1.3%) had very low-titer inhibitors (NusBA positive; NBA negative), and 13 (1.6%) had inhibitors (both NusBA and NBA positive). IgG1 was the most abundant FVIII-specific antibody subclass, and the highest titer levels were found for IgG4. In individuals without a reported history of inhibitor development, no clear differences were observed in antibody patterns between those who were minimally or highly exposed to FVIII concentrates. IgG4 subclass antibodies were only observed in persons with a reported history of FVIII inhibitor or in those with a currently detected (very low-titer) inhibitor. Conclusion In this cross-sectional study, we identified non-neutralizing antibodies in a relatively large proportion of persons with hemophilia A. In contrast, in our population, consisting of persons highly exposed to FVIII concentrates, (very low-titer) inhibitors were detected only in a small proportion of persons, reflecting a well-tolerized population. Hence, our findings suggest that only a small subpopulation of non-neutralizing FVIII-specific antibodies is associated with clinically relevant inhibitors.

Abstract
INTRODUCTION Plain film radiographs are recommended to assist in MRI safety screening of patients with unknown medical histories, especially in an emergency setting where patients might be unable to answer a safety questionnaire. This study assesses the performance of CT scout images, which have low radiation dose and are faster and easier to acquire compared to plain film radiographs, in finding and naming a range of head and body implants. METHODS A retrospective analysis of 40 CT Head and Neck (HN) scout images and 40 CT Chest, Abdomen and Pelvis (CAP) scout images was undertaken. A subset of these were chosen to include a range of common internal implants not identifiable externally to the patient. The images were assessed by three readers with varying levels of clinical experience in MRI who were asked to find and name any implants seen. RESULTS Collectively, all readers reached a sensitivity of 85 % in finding internal implants, regardless of their clinical experience or experience in reviewing CT images, and a minimum specificity of 95 %. Implants were correctly named in 74 % of the images presented. CONCLUSION CT scout images were able to reveal most of the implants included. However, clinical experience in reviewing the images enhances a reader's ability to identify the type of implant. IMPLICATIONS FOR PRACTICE In an emergency setting, imaging can be critical in the management of patients presenting with acute illnesses. In the unconscious or unresponsive patient, the use of CT scouts, where this is the only option available, could provide valuable MRI safety information prior to a scan, improving access to the MRI scan in a timely manner.

Abstract
INTRODUCTION Visceral leishmaniasis (VL) is a neglected tropical disease responsible for many thousands of preventable deaths each year. Symptomatic patients often struggle to access effective treatment, without which death is the norm. Risk prediction tools support clinical teams and policymakers in identifying high-risk patients who could benefit from more intensive management pathways. Investigators interested in using their clinical data for prognostic research should first identify currently available models that are candidates for validation and possible updating. Addressing these needs, we aim to identify, summarise and appraise the available models predicting clinical outcomes in VL patients. METHODS AND ANALYSIS We will include studies that have developed, validated or updated prognostic models predicting future clinical outcomes in patients diagnosed with VL. Systematic reviews and meta-analyses that include eligible studies are also considered for review. Conference abstracts and educational theses are excluded. Data extraction, appraisal and reporting will follow current methodological guidelines. Ovid Embase; Ovid MEDLINE; the Web of Science Core Collection, SciELO and LILACS are searched from database inception to 1 March 2023 using terms developed for the identification of prediction models, and with no language restriction. Screening, data extraction and risk of bias assessment will be performed in duplicate with discordance resolved by a third independent reviewer. Risk of bias will be assessed using the Prediction model Risk Of Bias ASsessment Tool (PROBAST). Tables and figures will compare and contrast key model information, including source data, participants, model development and performance measures, and risk of bias. We will consider the strengths, limitations and clinical applicability of the identified models. ETHICS AND DISSEMINATION Ethics approval is not required for this review. The systematic review and all accompanying data will be submitted to an open-access journal. Findings will also be disseminated through the research group's website (www.iddo.org/research-themes/visceral-leishmaniasis) and social media channels. PROSPERO REGISTRATION NUMBER CRD42023417226.

Abstract
BACKGROUND AND AIMS Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is an established treatment in selected patients with peritoneal metastases, delivered in the UK in specialist centres. HIPEC can be administered via the open coliseum technique as first described by Sugarbaker (O-HIPEC) or using a closed technique (C-HIPEC). Data comparing the safety and outcomes of these different approaches is limited. This study aims to compare morbidity and mortality rates of O-HIPEC and C-HIPEC following CRS for peritoneal metastases from colorectal cancer and appendiceal tumours. METHODS Consecutive patients undergoing CRS with open (05/2019-04/2020) and closed (05/2020-04/2021) HIPEC were identified from a prospectively maintained database. Baseline data including primary pathology, HIPEC agent and major operative procedures were analysed using Chi-squared and Fishers exact tests to ensure comparability of groups. Primary outcomes were 30- and 60-day postoperative mortality and morbidity (Common Terminology Criteria for Adverse Events, CTCAE). Secondary outcomes were length of critical care and overall hospital stay. In addition, morbidity and mortality were compared between HIPEC agents (mitomycin and oxaliplatin/5-fluorouracil). RESULTS 99 patients (39.3%) and 153 patients (60.7%) underwent O-HIPEC, C-HIPEC respectively. Groups were well matched for baseline demographics, pathology, and HIPEC agent. In the O-HIPEC and C-HIPEC groups respectively, the incidence of 60-day complications (CTCAE 1-4) was 40.4% vs 39.3% (chi squared 0.94) and severe complications (CTCAE 3-4) 14% vs 13% (Fisher's exact p = 1) There was no perioperative mortality but one death in each group within the follow up period. There was no difference in morbidity or mortality between those receiving mitomycin or oxaliplatin. CONCLUSION Closed administration of HIPEC is safe with no difference in post-operative morbidity or mortality compared to open HIPEC administration. Differences in longer term oncological outcomes including overall survival and disease-free survival between open and closed HIPEC techniques are yet to be determined.

Abstract
Monkeypox virus, now known as Mpox virus is a large, enveloped, double stranded deoxyribonucleic acid (DNA) virus belonging to the Orthopox viridae genus of the Poxviridae family. Though, Mpox, have earlier been endemic to only African countries, the 2022 outbreak has shown its rapid spread throughout the world. The May 2022 outbreak have shown primarily human to human transmission in contrast to animal to human transmission that had been seen previously. Recent data also suggest a possibility of a pre symptomatic spread. After an incubation period of 9 days, patients with Mpox can present with a prodrome of symptoms followed by a rash. If untreated, severe complications develop in the high-risk groups especially children and pregnant woman. Such groups of people will benefit from antiviral treatments. The current approach to prevent against it is pre-exposure and post exposure prophylaxis with vaccines. The vaccines that have been approved by Food and Drug Administration to date is ACAM2000 and JYNNEOS. Several diagnostic methods exist, among which polymerase chain reaction has proven to be the most specific and sensitive. In this review, we will discuss its epidemiology, the clinical manifestations, diagnostic modalities, complications, treatment approaches and preventive measures.

Abstract
Molecular appraoch for identification of unknown species by using Cytochrome b gene is an effective and reliable as compared with morphological based identification. For DNA barcoding universal molecular genes were used to identify the species. Cytochrome b is a specific gene used for identification purpose. DNA barcoding is a reliable and effective method compared to the different traditional morphological methods of specie identification. So,in the present study which was conducted to identify the species, a total of 50 fish samples were collected from five different sites. DNA was extracted by using the Phenol Chloroform method from muscle tissue. Five sequences were sequenced (one from each site), analyzed, and identified specific species as Pangasius pangasius. Identified sequences were variable in length from 369 bp (Site 1), 364 bp (Site 2), 364 bp (Site 3), 352 bp (Site 4), and 334 bp (Site 5). Identity matches on the NCBI database confirmed the specific specie as P. pangasius. A distancing tree was drawn to show maximum likelihood among the same and different species. Yet, in many cases fishes on diverse development stages are difficult to identify by morphological characters. DNA-based identification methods offer an analytically powerful addition or even an alternative tool for species identification and phylogenetic study. This work intends to provide an updated and extensive overview on the DNA based methods for fish species identification by using Cytochrome b gene as targeted markers for identification purpose.

Abstract
Abstract
Issue/problem
The United Kingdom (UK) hosts c.136,000 refugees and last year received the most asylum applications in two decades. Despite this, expertise in migrant health is not widespread in general practice, with few comprehensive toolkits available to support crucial initial health assessments of new arrivals.
Description of the problem
A large influx of Afghan refugees entered the UK in autumn 2021. In London, primary care practitioners quickly identified a lack of readily accessible, comprehensive guidance to support them in conducting health assessments for arrivals with a complex range of needs. This was compounded by many in primary care having little or no experience of migrant health.
Results
To address this gap in advice on conducting initial health assessments, a bespoke toolkit was created. The toolkit consolidated advice from a range of partners and resources: the UK Afghan migrant health guide, clinicians with humanitarian experience, front-line practitioners, Doctors of the World, and those leading on the health and public health response. The toolkit ensured greater consistency in the nature and content of assessments, considered not only primary needs but also broader wellbeing, and was responsive to both anticipated and known health priorities.
Lessons
The initial health assessment toolkit for Afghan migrants was well received by frontline staff and has implications for international practice in other areas providing similar health support. The toolkit and associated supporting information has formed a template that can be rapidly adapted to suit emerging needs, as has been done for new arrivals from Ukraine. This work has fed into best practice by the UK National Asylum Steering Group and is to be a case study for a WHO project on country-specific health assessments.
Key messages
• The toolkit is a proof of concept for partnership working towards holistic initial health assessments of new migrants in primary care, bringing together best evidence and pragmatic practice.
• This work has implications for other countries experiencing similar trends in migration and providing health support to an increasing number of new refugees.

Abstract
Background Timely identification of deteriorating COVID-19 patients is needed to guide changes in clinical management and admission to intensive care units (ICUs). There is significant concern that widely used Early warning scores (EWSs) underestimate illness severity in COVID-19 patients and therefore, we developed an early warning model specifically for COVID-19 patients.
Methods We retrospectively collected electronic medical record data to extract predictors and used these to fit a random forest model. To simulate the situation in which the model would have been developed after the first and implemented during the second COVID-19 ‘wave’ in the Netherlands, we performed a temporal validation by splitting all included patients into groups admitted before and after August 1, 2020. Furthermore, we propose a method for dynamic model updating to retain model performance over time. We evaluated model discrimination and calibration, performed a decision curve analysis, and quantified the importance of predictors using SHapley Additive exPlanations values. Results We included 3514 COVID-19 patient admissions from six Dutch hospitals between February 2020 and May 2021, and included a total of 18 predictors for model fitting. The model showed a higher discriminative performance in terms of partial area under the receiver operating characteristic curve (0.82 [0.80–0.84]) compared to the National early warning score (0.72 [0.69–0.74]) and the Modified early warning score (0.67 [0.65–0.69]), a greater net benefit over a range of clinically relevant model thresholds, and relatively good calibration (intercept = 0.03 [− 0.09 to 0.14], slope = 0.79 [0.73–0.86]). Conclusions This study shows the potential benefit of moving from early warning models for the general inpatient population to models for specific patient groups. Further (independent) validation of the model is needed. Supplementary Information The online version contains supplementary material available at 10.1186/s40635-022-00465-4.

Abstract
Abstract
Background
Brain metastases (BM) occur in approximately 10-30% of patients with breast cancer (BC). Patients with advanced breast cancer are living longer, and the incidence of BM are increasing. Stereotactic Radiosurgery (SRS) has emerged as a strategy to treat BM. We evaluated the outcomes and potential prognostic factors of patients with BM treated with SRS.
Material and Methods
Retrospective review of patients treated with linac-based SRS for BM from BC in a single tertiary centre between August 2017-September 2021. Overall survival (OS), intracranial progression-free survival (IPFS), and prognostic factors were evaluated using Kaplan-Meier analysis, log-rank test, and Cox proportional-hazards model.
Results
76 patients were included in the analysis. Out of these, 56 had first-line local treatment with SRS, either as primary (n=34) or adjuvant to surgery (n=22). Median age was 58 years old (range 37-86), and 88% had PS 0/1. One-year survival rate was 56%.
Median OS and IPFS from SRS was 16 months (95% CI 8-24) and 7 months (95% CI 2-12), respectively. However, there were significant differences in OS (p<0.001) and IPFS (p=0.001) based on molecular subtypes. Patients with triple-negative breast cancer (TNBC) (n=14) had median OS of 7 months (95% CI 2-12), ER+/HER2- (n=22) median OS of 22 months, ER-/HER2+ (n=8) median OS of 4 months (95% CI 0-9), and ER+/HER2+ (n=11) median OS of 36 months. Similar trend was seen with IPFS.
Patients with progressive extracranial disease compared to stable disease had shorter median OS (4 months vs 23 months, HR 2.4, p=0.01) and median IPFS (4 months vs 13 months, HR 2, p=0.03). Age ≥65 years was associated with shorter median OS (4 vs 23 months, HR 2.3, p=0.02). Patients with ≥4 brain metastases had shorter IPFS (4 months vs 11 months, HR 2.4, p=0.012), but no significant difference in OS. Volume of metastases did not affect outcome in this series.
30% of patients progressed intracranially after first-line SRS. 94 % had out-of-field recurrences, and 6% in-field recurrences. 59% had further SRS, 12 % WBRT, 6% surgery, and 23% had no further local treatment.
26 patients had second-line local treatment with SRS after first-line SRS (n=9), WBRT (n=9), or surgery +/- WBRT (n=8). There were no significant differences in outcome based on the modality of first-line local treatment.
Conclusion
SRS is an effective treatment for BM from BC. There were significant differences in survival based on age, molecular subtypes, and extracranial disease status.

Abstract
Background and objectives Treatment availability and comprehensive care have resulted in improved clinical outcomes for persons with hemophilia. Recent data on socioeconomic participation in the Netherlands are lacking. This study assessed participation in education, in the labor market, and social participation for persons with hemophilia compared with the general male population. Methods Dutch adults and children (5–75 years) of all hemophilia severities (n = 1009) participated in a questionnaire study that included sociodemographic, occupational, and educational variables. Clinical characteristics were extracted from electronic medical records. General population data were extracted from Statistics Netherlands. Social participation was assessed with the PROMIS Ability to Participate in Social Roles and Activities short form, with a minimal important difference set at 1.0. Results Data from 906 adults and children were analyzed. Participation in education of 20 to 24 year olds was 68% (general male population: 53%). Educational attainment was higher compared with Dutch males, especially for severe hemophilia. Absenteeism from school was more common than in the general population. The employment‐to‐population ratio and occupational disability were worse for severe hemophilia than in the general population (64.3% vs. 73.2% and 14.7% vs. 4.8%, respectively), but similar for nonsevere hemophilia. Unemployment was 5.4% (general male population: 3.4%). Absenteeism from work was less common (38% vs. 45.2%). Mean PROMIS score was similar to or higher than in the general population (54.2; SD 8.9 vs. 50; SD 10). Conclusion Socioeconomic participation of persons with nonsevere hemophilia was similar to the general male population. Some participation outcomes for persons with severe hemophilia were reduced.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) presents an urgent threat to global health. Prediction models that accurately estimate mortality risk in hospitalized patients could assist medical staff in treatment and allocating limited resources. AIMS To externally validate two promising previously published risk scores that predict in-hospital mortality among hospitalized COVID-19 patients. METHODS Two prospective cohorts were available; a cohort of 1028 patients admitted to one of nine hospitals in Lombardy, Italy (the Lombardy cohort) and a cohort of 432 patients admitted to a hospital in Leiden, the Netherlands (the Leiden cohort). The endpoint was in-hospital mortality. All patients were adult and tested COVID-19 PCR-positive. Model discrimination and calibration were assessed. RESULTS The C-statistic of the 4C mortality score was good in the Lombardy cohort (0.85, 95CI: 0.82-0.89) and in the Leiden cohort (0.87, 95CI: 0.80-0.94). Model calibration was acceptable in the Lombardy cohort but poor in the Leiden cohort due to the model systematically overpredicting the mortality risk for all patients. The C-statistic of the CURB-65 score was good in the Lombardy cohort (0.80, 95CI: 0.75-0.85) and in the Leiden cohort (0.82, 95CI: 0.76-0.88). The mortality rate in the CURB-65 development cohort was much lower than the mortality rate in the Lombardy cohort. A similar but less pronounced trend was found for patients in the Leiden cohort. CONCLUSION Although performances did not differ greatly, the 4C mortality score showed the best performance. However, because of quickly changing circumstances, model recalibration may be necessary before using the 4C mortality score.

Abstract
BackgroundHealth Literacy (HL) informs health behaviors such as follow-up with health care providers & management plans. Poor HL is linked to poor health outcomes & healthcare disparity. In addition to personal HL, health care providers/systems & Organizations can also empower patients by developing & providing educational resources that foster HL & support a patient’s understanding of their health condition (organizational HL). Patient educational handouts are frequently provided after a physician visit to supplement instructions/education & are often obtained from online resources accessible to both physicians & patients.Lupus, a multisystem disease, preferentially effects people of color, a group at higher risk of health disparities, & poor HL. It is paramount for lupus patients to understand their disease & management to optimize health outcomes & reduce health disparities. The provision of easy to read & comprehend patient educational resources are one way to address this need.ObjectivesThe Center for Disease Control (CDC) recommends the readability of patient educational material to be at eight-grade level, while the National Institute of Health (NIH) & the American Medical Association (AMA) recommend a level no higher than sixth-grade. The Readability & Comprehension (RC) of commonly available lupus-related patient educational materials are not known & may offer an opportunity to improve patient care & outcomes.MethodsWe searched for the RC of Lupus-related patient educational materials, available at the American College of Rheumatology (ACR) & Lupus Foundation of America (LFA) websites. These reputable national organizations are at the forefront of Lupus education & research. RC were evaluated using the following measures: Flesch Kincaid Readability Ease (FKRE), Flesch Kincaid Grade Level (FKGL), Gunning Fog Score (GFS), Simple Measure of Gobbledygook (SMOG) Index, Coleman Liau Index (CLI) & Automated Readability Index (ARI).FKRE score is a widely used measure of readability with scores ranging from 0-100 & higher scores denoting greater reading ease (Goal is >60). FKGL represents the U.S. school grade needed to comprehend the text (Target is 7th grade). GFS estimates the years of formal education required to understand the text on the first reading (Goal is 7-8). SMOG index estimates the years of education needed to comprehend written materials. CLI is used to assess the U.S. grade level necessary to comprehend text material. The ARI assesses how easy a text material is to learn & estimates the U.S. grade level necessary to comprehend a passage.Descriptives for RC were obtained & compared using t test between the two sources.ResultsThere were 12 patient educational pamphlets on Lupus available (4 from ACR & 8 from LFA). Mean (SD) FKRE & FKGL were 52.73 (11.44) & 10.46 (2.14) respectively (Table 1). Mean GFS & CLI exceeded 12, while mean ARI was 18.Table 1.Reading & Comprehension of Patient Educational Materials on LupusRC Test (Values are Mean (SD))AllACRLFAPFlesch Kincaid Reading Ease52.7347.1855.500.25(11.44)(4.93)(13.00)Flesch Kincaid Grade Level10.4610.7310.330.78(2.14)(0.64)(2.64)Gunning Fog Score12.1912.6511.960.41(1.78)(0.31)(2.19)SMOG Index8.949.68.610.27(1.41)(0.67)(1.60)Coleman Liau Index13.5114.6512.940.18(2.04)(1.34)(2.15)Automated Readability Index18.0211.121.470.49(23.13)(1.45)(28.27)There were no significant differences in the RC scores among patient educational materials from the ACR or LFA.ConclusionPatient educational materials on Lupus, available at the ACR & LFA websites, are not easy to read or comprehend, using standardized RC metrics. Additionally, they are not aligned with recommended reading levels suggested by leading organizations (CDC, NIH or AMA). Patient’s understanding is critical in a complex disease like lupus to optimize health outcomes.Revision of patient lupus educational resources at these websites, to target 6-7th grade RC metrics, is recommended & could be overseen by the development of a new taskforce.Disclosure of InterestsNone declared

Abstract
Introduction Inhibitor development affects about 30% of patients with severe haemophilia A (HA) and results from different environmental and genetic risk factors. Previously, we identified the missense variant rs3754689 in the LCT gene linked with this predisposition. Since rs3754689 variant is benign and is located in a conserved haplotype region, we hypothesized that the association signal captured by this variant is located in coinherited, neighbouring genes. Aim To identify novel genetic risk factors associated with inhibitor development in coding regions of R3HDM1, UBXN4, CXCR4, MCM6, DARS and miR128‐1 genes. Methods Targeted sequencing was performed in 246 severe HA patients (72 with and 174 without inhibitor): 181 previously and 65 newly enrolled. Results Forty‐one common and 152 rare variants passed the quality control. Logistic regression analysis of common variants identified rs3754689 and four additional variants (.011 < P < .047; FDR ranging .2‐.38). Logistic regression analysis performed only in the 220 Italian patients showed similar results (.004 < P < .05; FDR ranging .12‐.22). Three of these variants (rs3213892 and rs3816155 in the LCT intron 13 and rs961360 in the R3HDM1 intron10‐exon11 junction) may affect the expression of UBXN4 and R3HDM1, respectively. Rare variants did not show association with inhibitor development. Identified variants were not replicated in the multi‐ethnic SIPPET cohort of 230 severe HA patients. Conclusion Due to the limited sample size that may be responsible of the high FDR values, we could not confirm with certainty the analysed association. Further evaluation of the expression levels of analysed genes will confirm or not their role in inhibitor development.

Abstract
The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC's 7.97 ×103mm-3, RBC's 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

Abstract
This study was performed to compare the effects on facial nerve (FN) function of the deep supra-temporalis muscle subfascial approach (DSFA) and traditional fascial approach (TFA) for access to the temporomandibular joint (TMJ), via qualitative and quantitative evaluations. Thirty patients requiring open TMJ surgery were randomly allocated to one of two groups: group A patients underwent the DSFA approach, while group B patients underwent the TFA approach. The TMJ was accessed via modified endaural incision with temporal extension. Clinical examinations, FN conduction tests, and electromyography (EMG) of the frontalis and orbicularis oculi muscles were used to assess FN function. A FN function deficit was noted in 50% of the whole sample population immediately after surgery, with no statistically significant difference between the groups (P = 0.082). Overall, 37.5% of the total study population experienced temporary loss of frontalis muscle activity, while zygomatic nerve injury was seen only in 25% of group A. Within 2-6 months, normal function returned in both groups. Nerve conduction studies showed no statistically significant difference between the groups in terms of nerve amplitude or latency after surgery. However, EMG of orbicularis oculi activity showed a significant difference between the groups after 6 months (P = 0.010). The results suggest that the traditional dissection approach is more protective of the FN, especially the zygomatic branch, than the deeper dissection technique.

Abstract
INTRODUCTION Persons with hemophilia and hepatitis C virus (HCV) infection have a lower health-related quality of life (HRQoL) than those never HCV infected. However, it is unknown whether HRQoL after HCV eradication is comparable to individuals never HCV infected. We aimed to compare HRQoL between HCV-cured and never chronically HCV-infected persons with hemophilia. METHODS All persons with hemophilia in the Netherlands were invited for a nationwide study conducted in 2018-2019. For the current analysis, participants born before 1992 with data on HRQoL and HCV status were included. HCV status was collected from medical records. HRQoL was measured by RAND-36 questionnaire, with a minimally important difference set at 4.0 points. Multivariable linear regression was used to adjust for age, hemophilia severity, HIV status, and self-reported joint impairment. RESULTS In total, 486 persons were eligible; 180 were HCV cured and 306 never chronically HCV infected. Compared with those never HCV infected, HCV-cured individuals were older (57 vs. 53 years), more often had severe hemophilia (67% vs. 21%), and reported more impaired joints (median 3 vs. 0). Compared with those never HCV infected, adjusted RAND-36 domain scores of HCV-cured individuals cured were lower on all RAND-36 domains except Pain, ranging from a difference of 4.5 (95% CI, -8.8 to -0.3) for Physical functioning to 11.3 (95% CI, -19.4 to -3.1) for Role limitations due to physical problems. CONCLUSION Despite effective HCV treatment, HRQoL of HCV-cured persons with hemophilia is still lower than HRQoL of those never chronically HCV-infected on all RAND-36 domains. This implies that careful psychosocial follow-up and support are indicated.

Abstract
BACKGROUND The Patient-Reported Outcomes Measurement Information System (PROMIS) Profile-29 questionnaire is widely used worldwide, but it has not yet been validated in the Netherlands, nor in persons with hemophilia. OBJECTIVE To validate the Dutch-Flemish version of the PROMIS-29 Profile v2.01 in adults with hemophilia. METHODS Dutch males with hemophilia (all severities) completed questionnaires that contained sociodemographic and clinical characteristics, the PROMIS-29, RAND-36, and the Hemophilia Activities List (HAL). Structural validity of each subscale was assessed with confirmatory factor analysis (CFA). Internal consistency was calculated for each subscale with sufficient model fit in CFA. Construct validity was assessed by testing hypotheses about (1) correlations of each PROMIS-29 subscale with corresponding scales of RAND-36 and domains of HAL, and (2) mean differences in T-scores between subgroups with different hemophilia severities, self-reported joint impairment, and HIV infection status. We considered ≥75% of data in accordance with the hypotheses evidence for construct validity. RESULTS In total, 770 persons with hemophilia participated in this cross-sectional study. CFA revealed sufficient structural validity for five subscales: Physical Function, Depression, Sleep Disturbance, Ability to Participate in Social Roles and Activities, and Pain Interference. Internal consistency was high and Cronbach's alpha ranged from 0.79 for Sleep Disturbance to 0.96 for Pain Interference. Differences between clinical subgroups were in the expected direction. Construct validity was confirmed for Physical Function, Anxiety, Depression, Fatigue, Sleep Disturbance, and Pain Intensity. CONCLUSION This study revealed sufficient evidence for structural validity, internal consistency, and construct validity for most PROMIS Profile-29 subscales among people with hemophilia in the Netherlands.

Introduction
Although cardiovascular disease (CVD) and cancer remain the top two causes of death worldwide, novel therapeutics have resulted in a decreased mortality rate in both groups. Accordingly, there has been a heightened awareness of patients with cancer experiencing stress cardiomyopathy (SC). In patients with cancer, the emotional stress of the diagnosis of cancer is compounded by the physical stress of treatments such as surgery, chemotherapy, immunotherapy, and radiotherapy. Previous studies have shown that SC in patients with cancer is associated with higher odds of in-hospital mortality when compared to patients with SC alone. No studies have examined the differences between patients with active cancer and SC compared to patients with active cancer without SC.
Purpose
To explore the unique impact that a diagnosis of SC has on patients with specific types of cancer, so that clinicians may recognize these phenomena and reduce morbidity associated with this disease.
Methods
We queried the 2016 United States National Inpatient Sample, which is the largest publicly available all-payer inpatient healthcare database, to identify demographic characteristics and outcomes in patients with active cancer and SC.
Results
Of 30,195,722 adult hospitalized patients, 4,719,591 (15.63%) had active cancer of whom 568,239 (12.04%) had SC. Among patients with active cancer, patients with SC versus those without SC were significantly more likely to have the following characteristics: female sex, white race, commercial insurance, hypertension, anemia, thrombocytopenia, and coagulation disorder (p<0.003 for all variables). The five most common primary malignancies in patients with SC were breast (13.4%), lung (10.2%), skin (9.5%), colon (8.1%), and leukemia (4.8%) (Figure 1).
In machine learning-augmented propensity score-adjusted multivariable regression fully adjusting for age, race, income, and presence of metastases, the only primary malignancies that significantly increased the likelihood of SC were lung cancer (OR 1.25; p=0.003) and breast cancer (OR 1.81; p<0.001) (Table 1). In separate regression, neither SC alone nor having both SC and cancer was significantly associated with mortality. The presence of concomitant SC and breast cancer was significantly associated with reduced mortality (OR 0.48; p=0.032).
Conclusion
In patients with active cancer, SC was not associated with in-hospital mortality. In addition, patients with both SC and breast cancer had significantly reduced mortality when compared to all patients with cancer. Further investigation will be necessary to confirm these findings and determine the possible protective factors in patients with SC and breast cancer. Furthermore, clinicians should be aware, early during hospitalization, of the increased likelihood of SC in patients with lung cancer and breast cancer, in order to reduce morbidity associated with these diagnoses.

Abstract
INTRODUCTION We conducted six cross-sectional nationwide questionnaire studies among all patients with hemophilia in the Netherlands from 1972 until 2019 to assess how health outcomes have changed, with a special focus on patients >50 years of age. METHODS Data were collected on patient characteristics, treatment, (joint) bleeding, joint impairment, hospitalizations, human immunodeficiency virus and hepatitis C infections, and general health status (RAND-36). RESULTS In 2019, 1009 patients participated, of whom 48% had mild, 15% moderate, and 37% severe hemophilia. From 1972 to 2019, the use of prophylaxis among patients with severe hemophilia increased from 30% to 89%. Their median annual bleeding rate decreased from 25 to 2 bleeds. Patients with severe hemophilia aged <16 years reported joint impairment less often over time, but in those aged >40 years joint status did not improve. In 2019, 5% of all 1009 patients were positive for the human immunodeficiency virus. The proportion of patients with an active hepatitis C infection drastically decreased from 45% in 2001 to 2% in 2019 due to new anti-hepatitis C treatment options. Twenty-five percent had significant liver fibrosis even after successful therapy. Compared to the general male population, patients aged >50 years reported much lower scores on the RAND-36, especially on physical functioning. DISCUSSION/CONCLUSION Our study shows that increased use of prophylactic treatment and effective hepatitis C treatment have improved joint health and nearly eradicated hepatitis C infection in patients with hemophilia in the Netherlands. However, patients still suffer from hemophilia-related complications, especially patients aged >50 years.

Abstract
Introduction Although sports participation is advocated in people with haemophilia (PWH), detailed data concerning sports participation in Dutch PWH is lacking. Aim to assess sports participation in Dutch PWH (6‐65 years) compared to the Dutch general population (GP). Methods Data from a nationwide, cross‐sectional study in PWH were analysed. Sports participation (type, duration, frequency) was assessed by the Modifiable Activities Questionnaire (MAQ), limitations in activities using the (Paediatric) Haemophilia Activities List ((Ped)HAL). Sports in the two highest categories according to the National Hemophilia Foundation classification were considered high‐risk sports. Groups were compared using Chi‐square testing. Results A total of 524 Adult PWH (median age: 45 (IQR: 30–55); 37% severe) and 126 paediatric PWH (median age: 11 (IQR: 8–14); 52% severe) were included. Sports participation was higher in adults (70%) than the GP (58%) and similar to the GP in children (PWH: 68%, GP: 72%). High‐risk sports participation decreased with age in PWH: from 65% (6‐12 years) to 17% (50‐65 years), which was also observed in the GP. Sports participation in children was independent of severity (non‐severe: 67% vs. severe: 65%; P = 0.97), but not in adults (non‐severe: 75%, severe: 62%; P < 0.01). Non‐severe PWH played more high‐risk sports than severe PWH: children at 65% vs. 48% (P = 0.05), adults at 25% vs. 15% (P = 0.07). Discussion These results suggest that sports participation in PWH was comparable to the GP. Sports participation was dependent of haemophilia severity in adults. Children were more involved in high‐risk sports than adults. More studies on sports‐related injury‐risk are needed for adequate counselling.

Abstract
Background:Type I interferons such as Anifrolumab have been implicated in Systemic lupus erythematosus (SLE) pathogenesis on the basis of increased interferon-stimulated gene expression and genetic susceptibility. Little is known regarding its efficacy and safety profile.Objectives:To assess the efficacy and safety of Anifrolumab in patients with SLE.Methods:Electronic databases (PubMed, Embase, Scopus, Cochrane) were searched from inception until December 15th, 2020. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p<0.05. The primary outcome of interest was British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA). Secondary outcomes included the proportion of patients who achieved an SLE responder index of 4 (SRI-4) reduction of 50% or more in the Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI), reductions in the glucocorticoid dose and adverse effects.Results:A total of three studies1,2,3 with 839 participants (Anifrolumab=372, Placebo=467) were included in our analysis. Follow-up duration was at week 52. A statistically significant different was observed in the Anifrolumab arm in terms of BICLA response (OR 0.44 95%CI 0.34-0.59;p < 0.00001, I2=4), ≥50% reduction in CLASI activity score (OR 0.36 95%CI 0.21-0.60;p=0.0001, I2=0), glucocorticoid reduction (OR 0.41 95%CI 0.28-0.59;p<0.00001; I2=0) and SRI-4 response (OR 0.52 95% CI 0.30-0.90; p=0.02, I2=75). However, Adverse events were less likely in the placebo arm as compared to Anifrolumab (OR 1.54 95%CI 1.05-2.25; p=0.03; I2=0).Conclusion:Anifrolumab was found to be more effective than placebo for the management of SLE, but may also cause more severe adverse effects.References:[1]Morand EF, Furie R, Tanaka Y, Bruce IN, Askanase AD, Richez C, Bae SC, Brohawn PZ, Pineda L, Berglind A, Tummala R; TULIP-2 Trial Investigators.

Abstract
Background There is a need to identify patients with haemophilia who have a very low or high risk of developing inhibitors. These patients could be candidates for personalized treatment strategies. Aims The aim of this study was to externally validate a previously published prediction model for inhibitor development and to develop a new prediction model that incorporates novel predictors. Methods The population consisted of 251 previously untreated or minimally treated patients with severe haemophilia A enrolled in the SIPPET study. The outcome was inhibitor formation. Model discrimination was measured using the C‐statistic, and model calibration was assessed with a calibration plot. The new model was internally validated using bootstrap resampling. Results Firstly, the previously published prediction model was validated. It consisted of three variables: family history of inhibitor development, F8 gene mutation and intensity of first treatment with factor VIII (FVIII). The C‐statistic was 0.53 (95% CI: 0.46–0.60), and calibration was limited. Furthermore, a new prediction model was developed that consisted of four predictors: F8 gene mutation, intensity of first treatment with FVIII, the presence of factor VIII non‐neutralizing antibodies before treatment initiation and lastly FVIII product type (recombinant vs. plasma‐derived). The C‐statistic was 0.66 (95 CI: 0.57–0.75), and calibration was moderate. Using a model cut‐off point of 10%, positive‐ and negative predictive values were 0.22 and 0.95, respectively. Conclusion Performance of all prediction models was limited. However, the new model with all predictors may be useful for identifying a small number of patients with a low risk of inhibitor formation.

Abstract
Abstract
Background
We aimed to determine if the success of TESE and live-birth following TESE-ICSI can be predicted from readily available preoperative parameters for couples with azoospermia. Our methodology was as follows, this was a cohort study of couples who attended the fertility service (from 2009-2019) at an NHS hospital in whom the male partner was diagnosed with azoospermia and required conventional TESE with multiple biopsies to obtain sperm. Of 414 men included, 223 had successful TESE and of those 178 have used sperm in ICSI cycle(s). Predictive models were developed using logistic regression. We assessed model performance by internally validated concordance statistics and calibration plots. Successful sperm retrieval was defined as the presence of motile sperm which survived the freeze-thaw process and live-birth defined as delivery after 34 weeks of gestation.
Results
Successful TESE was associated with higher male age and lower FSH. The TESE model discriminated well with a c statistic of 0.81 (0.77-0.85). Live-birth was associated with lower maternal age, earlier ICSI cycle, and lower testicular volume. The live-birth model also discriminated well with a c statistic of 0.70 (0.64-0.76).
Conclusions
These results support the pragmatic counselling of couples diagnosed with azoospermia about the chances of success of the TESE procedure and of biological parenthood prior to surgical intervention. The models help to discriminate between men who have a high or low chance of successful TESE and couples who have a higher chance of achieving a live-birth after successful TESE. This will allow couples to make a better assessment of the balance of risk versus benefit prior to commitment to surgical interventions.

Abstract
BACKGROUND Treatment of patients with hemophilia has advanced over the past decades, but it is unknown whether this has resulted in a normal life expectancy in the Netherlands. OBJECTIVE This observational cohort study aimed to assess all-cause and cause-specific mortality in patients with hemophilia in the Netherlands between 2001 and 2018 and to compare mortality and life expectancy with previous survival assessments from 1973 onward. PATIENTS/METHODS All 1066 patients with hemophilia who participated in a nationwide survey in 2001 were followed until July 2018. RESULTS Information on 1031 individuals (97%) was available, of whom 142 (14%) deceased during follow-up. Compared with the general Dutch male population, mortality of patients with hemophilia was still increased (standardized mortality ratio: 1.4, 95% confidence interval: 1.2-1.7). Intracranial bleeding and malignancies were the most common causes of death. Estimated median life expectancy of patients with hemophilia was 77 years, 6 years lower than the median life expectancy of the general Dutch male population (83 years). Over the past 45 years, death rates of patients with hemophilia have consistently decreased, approaching the survival experience of the general population. Over the past decades, mortality due to human immunodeficiency virus and hepatitis C virus infections has decreased, death due to intracranial hemorrhages has increased, and death due to ischemic heart disease has remained consistently low over time. CONCLUSIONS Survival in patients with hemophilia in the Netherlands has improved over time but is still lower than that of the general population.

Abstract
This study investigates the removal of Pb(II) using polymer matrix membranes, cellulose acetate/vinyl triethoxysilane modified graphene oxide and gum Arabic (GuA) membranes. These complexation-NF membranes were successfully synthesized via dissolution casting method for better transport phenomenon. The varied concentrations of GuA were induced in the polymer matrix membrane. The prepared membranes M-GuA2–M-GuA10 were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, atomic force microscope and bio-fouling studies. Thermal stability of the membranes was determined by thermogravimetric analysis under nitrogen atmosphere. Dead end nanofiltration was carried out to study the perm- selectivity of all the membranes under varied pressure and concentration of Pb(NO3)2. The complexation-NF membrane performances were significantly improved after the addition of GuA in the polymer matrix membrane system. M-GuA8 membrane showed optimum result of permeation flux 8.6 l m−2 h−1. Rejection of Pb(II) ions was observed to be around 97.6% at pH 9 for all the membranes due to electrostatic interaction between CA and Gum Arabic. Moreover, with the passage of time, the rate of adsorption was also increased up to 15.7 mg g−1 until steady state was attained. Gum Arabic modified CA membranes can open up new possibilities in enhancing the permeability, hydrophilicity and anti-fouling properties.

Abstract
Abstract
Background
Percutaneous coronary interventions (PCIs) are often aimed at the culprit vessel in acute coronary syndromes (ACSs) followed by revascularisation of other stenoses later in the index hospitalisation or shortly after discharge. PCI delay of non-culprit coronary vessels stenoses is supported by lower contrast fluid use and thrombocyte aggregation. Distinct coronary interventions increase the risk of both non- and coronary artery complications, e.g. acute abdominal and periphery artery bleeding, suggesting undertaking all PCIs at the same time.
Purpose
To assess the effect on mortality and re-myocardial infarction (MI) of immediate versus staged revascularisation in multivessel coronary disease, with the latter constrained to initial PCI of the culprit coronary vessel.
Methods
The syntax of “randomised controlled trial (RCT) & acute coronary syndrome & complete revascularisation” was undertaken in PubMed.
Clinical characteristics were gathered at the index hospitalisation. The intervention scenario was acute coronary syndrome or not.
Meta-analyses calculated relative risk (RR) reductions on outcomes of 1) mortality and 2) re-MI. Meta-regression assessed linear difference between interventional treatment benefits and baseline characteristics.
Results
A total of 148 studies was found. Of those, 8 was found eligible for further analyses and their baseline characteristics are shown in Table 1.
Comparison of immediate versus staged revascularisation on mortality was nonsignificant (RR, 1.19; 95% CI: 0.78–1.81, p=0.43) (Figure 1). The impact of Immediate vs staged revascularisation on re-MI was also nonsignificant (RR, 0.83; 95% CI: 0.44–1.55, p=0.56). Meta-regression found no associations between the outcomes and study characteristics (not shown).
Conclusion
The intervention of immediate compared to staged revascularisation assessed on outcomes of all-cause mortality and re-MI were nonsignificant.

Abstract
At the time of writing, coronavirus disease-2019 (COVID-19) has affected 6.42 million people globally and over 380,000 deaths, with the United Kingdom now having the highest death rate in Europe. The plastic surgery department at Leeds Teaching Hospitals put necessary steps in place to maintain an excellent urgent elective and acute service whilst also managing COVID-positive medical patients in the ward. We describe the structures and pathways implemented together with complex decision-making, which has allowed us to respond early and effectively. We hope these lessons will prove a useful tool as we look to open conversations around the recovery of normal activity.

Abstract
Background Excessive body fat is the leading cause of many metabolic disorders. Therefore, assessing levels of body fat associated with risk of disease in specific populations is crucial. The present study aimed to identify optimal cut-off values of body fat composition including total body fat, body fat percentage, visceral fat, and trunk fat, in order to predict metabolic risk in the Qatari population. Methods This cross-sectional study was based on Qatar Biobank data of 2407 Qatari adults (1269 male and 1138 female) aged 21–70 years old. Individuals’ height, weight and body fat percentage were obtained. Blood test data including lipid profile, blood glucose and HbA1c data were also obtained. The area under the curve was calculated using ROC analysis to obtain the body fat percentage associated with risk of disease. Results The cut-off points for total fat for those aged < 40 were 34.0 kg, and for those aged ≥40 were 30.7 kg and 35.6 kg in men and women, respectively. The cut-off for body fat percent for those aged < 40 were 35.1 and 45.1%, and for those aged ≥40 were 34.8 and 46.3% in men and women, respectively. The cut-off points for trunk fat percent for those aged < 40 were 19.5 and 22.4%, and for those aged ≥40 were 21.6 and 23.4% in men and women, respectively. The cut-off points for visceral fat percent for those aged < 40 were 1.4 and 1.0%, and for those aged ≥40 were 1.9 and 1.4% in men and women, respectively. Conclusion This study established Qatari adult-specific cut-off values of body fat for different age and gender groups.

Abstract
UNLABELLED This analysis examined costs/resources of 141 women with vertebral fractures, randomised to a home exercise programme or control group. Total, mean costs and the incremental cost-effectiveness ratio (ICER) were calculated. Quality of life was collected. Cost drivers were caregiver time, medications and adverse events (AEs). Results show adding an exercise programme may reduce the risk of AEs. INTRODUCTION This exploratory economic analysis examined the health resource utilisation and costs experienced by women with vertebral fractures, and explored the effects of home exercise on those costs. METHODS Women ≥ 65 years with one or more X-ray-confirmed vertebral fractures were randomised 1:1 to a 12-month home exercise programme or equal attention control group. Clinical and health system resources were collected during monthly phone calls and daily diaries completed by participants. Intervention costs were included. Unit costs were applied to health system resources. Quality of life (QoL) information was collected via EQ-5D-5L at baseline, 6 and 12 months. RESULTS One hundred and forty-one women were randomised. Overall total costs (CAD 2018) were $664,923 (intervention) and $614,033 (control), respectively. The top three cost drivers were caregiver time ($250,269 and $240,811), medications ($151,000 and $122,145) and AEs ($58,807 and $71,981). The mean cost per intervention participant of $9365 ± $9988 was higher compared with the mean cost per control participant of $8772 ± $9718. The mean EQ-5D index score was higher for the intervention participants (0.81 ± 0.11) compared with that of controls (0.79 ± 0.13). The differences in quality-adjusted life year (QALY) (0.02) and mean cost ($593) were used to calculate the ICER of $29,650. CONCLUSIONS Women with osteoporosis with a previous fracture experience a number of resources and associated costs that impact their care and quality of life. Caregiver time, medications and AEs are the biggest cost drivers for this population. The next steps would be to expand this feasibility study with more participants, longer-term follow-up and more regional variability.

Abstract
Objectives: In hemophilia A the presence of non-neutralizing antibodies (NNAs) against Factor VIII (FVIII) may predict the development of neutralizing antibodies (inhibitors) and accelerate the clearance of administrated FVIII concentrates. This systematic review aimed to assess: (1) the prevalence and incidence of NNAs in patients with congenital hemophilia without inhibitors and (2) the association between NNAs and patient and treatment characteristics. Methods: We conducted a search in MEDLINE, Embase, Web of Science and the Cochrane database. We included cross-sectional and longitudinal studies reporting on NNAs in patients with hemophilia A and B, who were inhibitor-negative at the start of the observation period. Data were extracted on: hemophilia type and severity, patient and treatment characteristics, NNA prevalence and incidence, NNA assays and inhibitor development. Two independent reviewers performed study selection, data extraction and risk of bias assessment, using adapted criteria of the Joanna Briggs Institute. Studies were classified as high-quality when ≥5/9 criteria were met. NNA assays were classified as high-quality when both quality criteria were met: (1) use of positive controls and (2) competition with FVIII to establish FVIII-specificity. We reported NNA prevalence and incidence for each study. The pooled NNA prevalence was assessed for well-designed studies in previously treated patients, employing high-quality NNA assays. Results: We included data from 2,723 inhibitor-negative patients with hemophilia A, derived from 28 studies. Most studies were cross-sectional (19/28) and none reported on NNAs in hemophilia B. Study design was of high quality in 16/28 studies and the NNA assay quality was high in 9/28 studies. Various NNA assays were used, predominantly ELISA (18/28) with different cut-off values. We found a large variety in NNA prevalence (Range, 0–100%). The pooled NNA prevalence in high-quality studies was 25% (95% CI, 16–38%). The incidence of new NNA development was reported in one study (0.01 NNA per person-exposure day). Conclusion: This systematic review identified studies that were heterogeneous in study design, patient population and NNA assay type, with NNA prevalence ranging from 0 to 100% in inhibitor-negative patients with hemophilia A. The pooled NNA prevalence was 25% in high-quality studies including only previously treated patients and performing high-quality NNA assays.

Abstract
Background Human immunodeficiency virus (HIV) is a pandemic disease affecting all regions across the globe and Nigeria having the second highest prevalence worldwide. Highly active antiretroviral therapy (HAART) has profound negative effect on the optic nerve even though (HAART) has improved the health status of the affected individuals and overall reduction in mortality. Imaging modality especially ultrasound has a great role in the assessment of the optic nerve because of its availability, affordability, and easy operability with reliable sensitivity. Subjects and Methods This cross-sectional study was conducted at the Department of Radiology and Ophthalmology, AKTH, Kano, from October 2017 to June 2018. A total of 143 consenting HIV-positive adults age 18-60 years on HAART were recruited. Optic nerve sheath diameter (ONSD) of each eye was measured using 11-14 MHz linear transducer. Ethical approval was obtained from the ethic and research committee of the hospital. Results The mean ONSD value of the right eye was 3.49 mm ± 1.04 standard deviation (SD) and 3.55 mm ± 1.11 SD for the left eye. The optic nerve diameter was found to be larger on the left eye and increased slightly with age (P < 0.05). There was nonsignificantly higher values of ONSD among female (3.59 mm ± 1.12 SD) when compared with males (3.332 mm ± 0.878) with P value >0.005. Conclusion ONSD values among HIV-positive patients are significantly higher in the left eye and among female subjects. Also, patients with HIV on HAART have thicker optic nerves when compared with general population in Kano, Nigeria.

Abstract
The non-isothermal drying behavior and kinetics of human feces (HF) were investigated by means of thermogravimetric analysis to provide data for designing a drying unit operation. The effect of heating rate and blending with woody biomass were also evaluated on drying pattern and kinetics. At low heating rate (1 K/min), there is effective transport of moisture, but a higher heating rate would be necessary at low moisture levels to reduce drying time. Blending with wood biomass improves drying characteristics of HF. The results presented in this study are relevant for designing non-sewered sanitary systems with in-situ thermal treatment.
