Abstract
INTRODUCTION The optimal role of nerve conduction studies (NCS) in management of carpal tunnel syndrome (CTS) is unclear, with no standardised guidance. This study aimed to identify variation in practice in the initial diagnosis of patients with suspected CTS, alongside evaluating how NCS findings influence clinical decision making. METHODS A national multicentre collaborative survey was conducted in 2021. All centres providing surgery for CTS were invited to participate, primarily via social media. All middle-senior grade orthopaedic/plastic surgeons and advanced care practitioners that regularly manage new referrals for suspected CTS were eligible to respond. Local representatives at each participating site submitted their responses to a central team who collated and analysed the results. RESULTS A total of 137 healthcare professionals responded from 18 UK NHS Trusts. Of these 137, 124 (91%) reported not employing any validated clinical questionnaires in their routine practice, preferring to rely on clinical diagnosis and/or NCS if available, whereas 84 (61%) utilised NCS to aid diagnosis, with significant differences among professionals with differing experience (p < 0.01). The most common methods for determining the severity of CTS were history, examination and NCS. In symptomatic CTS with confirmatory NCS, over 50% of clinicians would choose surgical decompression as their first-line intervention. In cases of either negative NCS or atypical presentation, 37% and 51%, respectively, would consider conservative management (e.g. splintage) or steroid injection first line. CONCLUSIONS With growing waiting lists for NCS and surgery, national consensus guidelines should be developed to support decision making, while maximising efficient utilisation of increasingly constrained resources.

Abstract
Introduction Forearm fractures are common in children. The remodelling capacity of growing long bones in children makes these potentially forgiving injuries, recovering with good outcomes despite minimal intervention. Clinicians rely on radiological characteristics that vary with age to guide treatment decisions and minimise adverse sequelae. The purpose of this review was to consolidate the evidence base of radiological indications for intervention in paediatric mid-shaft forearm fractures. Materials and methods The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were followed for this review. Citable research output reporting radiological criteria for mid-shaft forearm fractures in paediatric patients (age ≤16 years) was screened and analysed to ascertain acceptable radiological criteria for non-operative management. Results A total of 2,059 papers were initially identified; 14 were selected following screening. Sagittal angulation >15°, coronal angulation >10°, and/or >50% (or >1cm) translation were the most common radiological indications for intervention in children aged 0 to 10 years. For children over 10 years of age, the most common radiological indication for intervention was sagittal angulation >10°, coronal angulation >10°, and/or >50% (or >1cm) translation. Conclusion This study revealed a scarcity of high-quality evidence to guide management and significant variation in outcome reporting throughout the published literature. Since Noonan and Price's 1998 recommendations, there has been no significant evolution in the evidence-base guided threshold for intervention in paediatric mid-shaft forearm fractures. There remains a pressing need for a robust multicentre observational study using the patient-reported outcome measurement information system (PROMIS) to address this complex and controversial area of uncertainty in paediatric trauma management.

Abstract
Aggressive angiomyxoma is a rare mesenchymal tumour, primarily arising in the soft tissue of the pelvis and perineum in women of reproductive age. There is a paucity of evidence on optimal management because of the rarity of these tumours, but the consensus has been for surgical excision. We present the case of a 65-year-old woman who was admitted with left-sided buttock pain and initially diagnosed with a perianal abscess. She underwent examination under anaesthesia rectum with surgical excision of the lesion, subsequent histopathological and immunochemical analysis was suggestive of aggressive angiomyxoma. To complement our case report, we also present a literature review focusing on aggressive angiomyxoma in the ischioanal fossa (also known as the ischiorectal fossa) with only eight cases of primary aggressive angiomyxoma involving the ischioanal fossa documented to date. The primary aims of this case report and literature review are to familiarise clinicians with the clinical, histopathological and immunochemical features of these tumours, and to increase appreciation that despite the rarity of aggressive angiomyxoma, it might be considered in the differential diagnosis of ischioanal lesions.

Abstract
INTRODUCTION Healthcare faces growing challenges. With reports of diminishing research output from the UK and Ireland in the leading surgical journals, this study aimed to ascertain whether this trend had been echoed in the trauma and orthopaedic literature. MATERIALS AND METHODS Citable research output from the 10 globally leading trauma and orthopaedic journals was analysed from five individual years, over a 20-year period, to ascertain trends in absolute output, geographical mix, and level of evidence. RESULTS The overall number of published articles fell by 14.5%. North America saw the greatest decline (-8.0%), followed by Japan (-5.6%) and Europe (-3.3%). The UK and Ireland (+2.9%) and the rest of the world (+13.9%) saw rising output. A decline in lower (levels IV and V) and a rise in higher (levels I, II and III) quality evidence was observed. The UK and Ireland had a greater proportion of higher-quality studies than North America and Japan, but lower than Europe and the rest of the world. The impact factor of the leading journal rose from 4.47 to 7.01. DISCUSSION The research landscape has evolved, with leading journals placing greater emphasis on higher-quality evidence. UK and Irish research output remains stable, contributing 14% of the most highly cited publications in 2018, and challenging North America's dominance with a greater proportion of level I and II evidence in the leading journals. CONCLUSION With the growing emergence of Europe and the rest of the world, UK and Irish authors must build upon the region's output despite political challenges such as Brexit. Increasing international collaboration will continue to play an important role.

Abstract
BACKGROUND The VITamin D and OmegA-3 TriaL (VITAL) is a completed randomized, placebo-controlled trial of vitamin D3 (2000 IU/day) and marine omega-3 (1 g/day) supplements in the primary prevention of cancer and cardiovascular disease. Here we examine baseline and change in 25-hydroxyvitamin D (25(OH)D) and related biomarkers with randomized treatment and by clinical factors. METHODS Baseline 25(OH)D was measured in 15,804 participants (mean age 68 years.; 50.8% women; 15.7% African Americans) and in 1660 1-year follow-up samples using liquid chromatography-tandem mass spectrometry and chemiluminescence. Calcium and parathyroid hormone (iPTH) were measured by chemiluminescence and spectrophotometry respectively. RESULTS Mean baseline total 25(OH)D (ng/mL ± SD) was 30.8 ± 10.0 ng/mL, and correlated inversely with iPTH (r = -0.28), p < .001. After adjusting for clinical factors, 25(OH)D (ng/mL ± SE) was lower in men vs women (29.7 ± 0.30 vs 31.4 ± 0.30, p < .0001) and in African Americans vs whites (27.9 ± 0.29 vs 32.5 ± 0.22, p < .0001). It was also lower with increasing BMI, smoking, and latitude, and varied by season. Mean 1-year 25(OH)D increased by 11.9 ng/mL in the active group and decreased by 0.7 ng/mL in placebo. The largest increases were noted among individuals with low baseline and African Americans. Results were similar for chemiluminescent immunoassay. Mean calcium was unchanged, and iPTH decreased with treatment. CONCLUSION In VITAL, baseline 25(OH)D varied by clinical subgroups, was lower in men and African Americans. Concentrations increased with vitamin D supplementation, with the greatest increases in those with lower baseline 25(OH)D. The seasonal trends in 25(OH)D, iPTH, and calcium may be relevant when interpreting 25(OH)D levels for clinical treatment decisions. CLINICAL TRIAL REGISTRATION VITAL ClinicalTrials.gov number NCT01169259.

Abstract
UNLABELLED Tc99m-sestamibi dual-time imaging is a standard tool for localization of adenomas/hyperplasia in hyperparathyroidism. We investigated the degree and causes of localization failure among different types of hyperparathyroidism. Pre-operative parathyroid hormone levels and size of the gland were major determinants of Tc99m-sestamibi positivity; 123I scan may be helpful in localization failures. INTRODUCTION Tc99m-sestamibi dual-time imaging is a standard tool for localization of adenomas/hyperplasia in hyperparathyroidism. However, parathyroid adenomas/hyperplasia has been reported to washout as fast as normal thyroid tissue ("rapid washout") which may lead to diagnostic failure. We aimed to evaluate the determinants of rapid washout and to determine the role of subtraction imaging for detection of parathyroid adenomas/hyperplasia with rapid washout. METHODS Retrospective analysis of patients with hyperparathyroidism who have undergone Tc99m-sestamibi dual-time imaging and parathyroid surgery. Rapid washout was correlated to the type of hyperparathyroidism in surgically confirmed cases. Biochemical and pathological data were reviewed. RESULTS A total of 135 hyperparathyroidism patients met the inclusion criteria. Ninety-six (72%), 29 (21%), and 10 (7%) had primary, secondary, and tertiary hyperparathyroidisms, respectively. Rapid washout was identified in 28/87 glands (32%), 14/53 glands (26%), and 1/16 glands (6%) with primary, secondary, and tertiary hyperparathyroidisms, respectively. Glands that were positive on late-phase Tc99m-sestamibi scans were significantly large being 1.7 (IQR 1.4-2.3) vs. 1.45 (IQR 1-2) cm (p = 0.003). High parathyroid hormone levels (PTH) were associated with early-phase Tc99m-sestamibi positivity in both primary (p = 0.01) and secondary hyperparathyroidism (p = 0.03) but not with last phase (p = 0.11, p = 0.37, respectively). Correlative imaging with subtraction scintigraphy was positive in 14/16 (87.5%) parathyroid adenomas. CONCLUSION Pre-operative PTH levels and size of the gland were major determinants of Tc99m-sestamibi positivity on early-phase Tc99m-sestamibi scans, whereas size is an independent predictor of late-phase Tc99m-sestamibi positivity. Subtraction scintigraphy might be a useful tool in suspected cases of rapid washout adenomas/hyperplasia.

Abstract
Abstract
Purpose: To evaluate the psychosocial impact of semi-annual dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) screening in women at high-risk for breast cancer.
Background: For women with BRCA1 and BRCA2 mutations and/or a personal or family history of breast cancer, annual breast MRI has shown improved sensitivity and cancer detection compared to mammography. However, MRI's heightened sensitivity may lead to increased: false positives requiring additional follow-up biopsy/imaging; iatrogenic risk; and psychosocial distress, which all may negatively impact women's overall health-related quality of life.
Methods: Between 2004 and 2016, we assembled a prospective cohort of high-risk women undergoing semi-annual DCE-MRI and annual mammography. We reviewed a subset of this group. Participants completed psychosocial assessments at baseline and 6-month visits using the following measures: coping (MBSS); state/trait anxiety (STAI-S/T); depression (BDI-II); risk perception; and mental health (SF-36). Participants were classified according to Monitor or Blunter coping style. Mixed-effects logistic regressions models examined effects of demographics on psychosocial changes over time.
Results: 295 women were recruited to the study; 44% of the study participants had pathogenic mutations in BRCA1 or BRCA2 genes. 232 of 295 enrolled participants (78.6%) completed psychosocial assessments. For the total population: median age 44y (range: 21-73), 71% ≥college/post-graduate education; 84% Caucasian; 8% African American; 2% Latino; 99% with health insurance; 72% annual income of >$60,000. One third of women had a personal cancer history. Participants were evenly split between baseline Monitoring and Blunting coping style (49% and 51%, respectively). No significant differences were found between demographics (age, race, income, mutation, cancer type, cancer history) or psychosocial factors (baseline trait anxiety (p =0.64), depression (p =0.65), SF36 global health (p=0.66). After adjusting for education, race, cancer history and coping, women with ≥$60,000 income had lower trait anxiety (p<0.000) and greater mental health (p<0.001) than those with <$60,000 income. Over time, change in trait anxiety varied by coping (p=0.0006): Blunters did not experience significant changes in trait anxiety (p=0.072) while Monitors had significant diminished trait anxiety over time (p<0.001). For depression, women with ≥$60,000 income and college educated had lower BDI-II depression (p<0.000). Yet, women with a cancer history had significantly greater BDH-II depression (p= 0.048). Mental health over time varied by race as non-whites had greater gains in mental health (p=0.001) over time than whites (p=0.03).
Conclusion: Semi-annual DCE-MRI did not cause a significantly elevated state anxiety or depression, nor was there a significant decline in mental health over time for groups regardless of cancer history and genetic mutation status. Coping style may have an impact on psychosocial outcomes for those undergoing heightened surveillance over time.

Abstract
Introduction Pelvic radiography is a frequent investigation. European guidelines aim to ensure appropriate use and adequate quality. When initial images are inadequate, repeat radiographs are often required, which may have significant patient safety and economic implications. Objectives The study aimed to assess the adequacy of pelvic imaging across three orthopaedic centres, to identify causes for inadequate imaging and to establish the cost of inadequate imaging from financial and patient safety perspectives. Methods Pelvic radiographs were identified on Picture Archiving and Communication System software at three UK hospitals. Radiographs were assessed against European guidelines and indications for repeat imaging were analysed. Results A total of 1,531 sequential pelvic radiographs were reviewed. The mean age of patients was 60 years (range 5 months to 101 years). Of this total, 51.9% of images were suboptimal, with no significant difference across the three hospitals (P > 0.05). Hospital 3 repeated radiographs in 6.3% of cases, compare with 18.1% and 19.7% at hospitals 1 and 2, respectively (P > 0.05). Hospital 3 identified pathology missed on the initial radiograph in 1% of cases, compared with 5.4% and 5.5% at hospitals 1 and 2, respectively (P > 0.05). Out-of-hours imaging is associated with a higher rate of suboptimal quality (69.1%) compared with normal working hours (51.3%; P = 0.006). Adequacy rates vary with age (χ 2 = 43.62, P < 0.001). Risk of having a suboptimal radiograph increases above the age of 60-years (χ 2 = 4.45, P < 0.05). The annual cost of repeat radiographs was £56,200 per hospital. Discussion and conclusion High rates of pelvic radiograph inadequacy can lead to missed pathology and the requirement for repeat imaging, which has significant patient safety and financial implications. Risk factors for inadequate radiographs include older patients and those having out-of-hours imaging.

Abstract
BackgroundPrevious studies have reported depressive symptoms in patients with persistent delusional disorder (PDD). Patients with PDD and depression may need antidepressants for treatment.AimThe aim of the study was to compare the sociodemographic profile, clinical presentation and treatment response in patients with PDD with and without comorbid depressive symptoms.MethodsWe conducted a retrospective chart review of patients diagnosed with PDD (ICD-10) from 2000 to 2014 (n = 455). We divided the patients into PDD + depression (n = 187) and PDD only (n = 268) for analysis.ResultsOf the 187 patients with PDD + D, only eighteen (3.9%) were diagnosed with syndromal depression. There were no significant differences in sociodemographic profile including sex, marital and socioeconomic status (all P > 0.05). PDD + D group had a significantly younger age at onset ([PDD + D: 30.6 9.2 years vs. PDD: 33.5 11.1 years]; t = 2.9, P < 0.05). There was no significant difference between the clinical presentation including mode of onset, the main theme of their delusion and secondary delusions (all P > 0.3). However, comorbid substance dependence was significantly higher in patients with PDD only. (χ2 = 5.3, P = 0.02). In terms of treatment, response to antipsychotics was also comparable ([> 75% response: PDD + D = 77/142 vs. PDD = 106/179); χ2 = 1.9, P = 0.3). There was a significant difference between the two groups in terms of antidepressant treatment ([PDD + D = 32/187; 17% vs PDD: 17/268; 6%), χ2 = 12.9, P = 0.001).DiscussionPatients with PDD + D had significantly earlier onset of illness. These patients may require antidepressants for treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionPharmacogenetic studies in obsessive-compulsive disorder (OCD) primarily focussing on serotonergic and dopaminergic polymorphisms, provided inconsistent findings. There is recent evidence for glutamatergic abnormalities in OCD.AimsExamine the association glutamatergic genes with serotonin reuptake inhibitor (SRI) response in OCD.ObjectivesTo study pharmacogenetic association between SLC1A1 and GRIN2B polymorphisms with SRI response in OCD.MethodsDSM-IV OCD patients were recruited from a specialty OCD clinic and evaluated using the Yale-Brown obsessive compulsive scale (YBOCS), Mini International Neuropsychiatric Interview (MINI) plus, Clinical Global Impression scale (CGI). They were subsequently reassessed with YBOCS and CGI. To study extreme phenotypes, we included only full responders (> 35% YBOCS improvement and CGI-I score of 1 or 2) to any SRI (n = 191) and non-responders (< 25% YBOCS improvement and CGI-I score ≥ 4) to adequate trial of at least two SRIs (n = 84). Partial responders were excluded. Genotyping was performed using an ABI9700 PCR machine.ResultsGenotype frequencies did not deviate significantly from the values predicted by the Hardy-Weinberg equation. Case-control association analyses revealed no significant association between genotype/allele frequencies with SRI response.ConclusionOur data does not show any association between polymorphisms in glutamatergic genes and SRI response in OCD though such associations have been found in other studies. More SNP's in the same gene could be responsible for the pharmacogenetic associations. More homogenous sample considering symptom dimensions and other phenotypic variables may be needed. It may be critical to go beyond “usual suspect” candidate gene research. In this regard, a novel approach to identify SRI response biomarkers is the use of cellular models.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
As a pediatric hematologist oncologist with clinical and research interests in thrombosis in high-risk pediatric populations, and also as a member of the ISTH Early Career Task Force, I had the opportunity to develop a guidance document on 'Thromboprophylaxis for central venous catheters in the pediatric population' for the 'Guidelines and Guidance Documents' committee. In this communication, I share my experiences to date; I discuss my excitement and initial success, the steep learning curve required to build research acumen, the lessons learnt, and the opportunities and challenges faced. My experience with preparing the guidance document was much more than writing 'just another guidance document'.

Abstract
Background:
The coexistence of hypertension (HTN) and insulin resistance (IR) substantially increases cardiovascular risk (CVR) and diabetes (DM) perhaps by endothelial dysfunction from low-grade chronic inflammation and oxidative stress. South Asian immigrants in United States (SA-USA) have a high salt consumption, IR, and salt sensitivity. The triglyceride (TG)/ HDL ratio is a known correlate of IR with ratios ≥3.5 associated with high risk. It is unknown whether SA-USA have a coexistence of HTN, IR, and DM resulting in high CVR.
Methods:
We reviewed the clinical history and Vertical Auto Profile technology (VAP) + lipid panel utilizing ultracentrifugation to directly measure lipid sub-fractions, for 348 participants (42% women) of the South Asian Cardiovascular Registry. Prevalent DM and Pre-DM were defined as HbA1c ≥ 6.5 and 5.7-6.4, respectively.
Results:
Of the 348 participants, mean age 55.3 years, 128 had HTN and were stratified into clinical risk groups based on fasting TG (mg/dL) levels: TG<150 (n=69), TG 150-199 (n=24), TG 200-499 (n=32), TG>500 (n=3). The corresponding TG/HDL ratios were: 1.7, 3.5, 6.2, and 20.4, respectively; the median TG (mg/dL) levels were: 100, 182, 268, and 572, respectively; the median LDL (mg/dL) levels were: 113, 144, 133, 102, respectively; the rates of DM were: 13%, 17%, 38%, and 67%; and the rates of Pre-DM/DM were: 62%, 63%, 78%, and 67%, respectively. Relative Risk for DM with TG/HDL≥ 3.5 was 3.6 (46 % had TG/HDL ≥ 3.5).
Conclusions:
South Asian immigrants participating in a community registry have: 1) A high rate of coexistence of HTN and IR portending a very high relative risk of diabetes. 2) A discordance of LDL levels and IR in patients with HTN. As IR gets higher, the relative risk of diabetes goes up but LDL levels decline.
Clinical Implications:
South Asian immigrants in the United States have a diet that is very high in salt, simple carbohydrates, and saturated fat. Many are vegetarian with no consumption of fish. Public health efforts to help reduce risk of CVD in South Asian immigrants should focus on low salt diet, with consumption of multigrain complex carbohydrates, poly-unsaturated fatty acids, omega-3 fatty acids, and lifestyle changes to reduce metabolic syndrome, diabetes, and hypertension.

Abstract
IntroductionThere is a lack of pharmacological trials studying drug response in Persistent Delusional Disorder (PDD) to guide clinical practice. Available reviews of retrospective data indicate good response to second-generation antipsychotics, but even such data from India is sparse.Objectives and aimsWe aimed to compare the response of acute PDD to risperidone and olanzapine in our retrospective review.MethodsWe conducted a retrospective chart review of patients diagnosed with PDD (ICD-10) from 2000 to 2014 (n = 455) at our Center. We selected the data of patients prescribed either olanzapine or risperidone for the purpose of this analysis. We extracted data about dose, drug compliance and response, adverse effects, number of follow-up visits and hospitalizations. The study was approved by the Institute Ethics Committee.ResultsA total of 280/455 (61%) were prescribed risperidone and 86/455 (19%) olanzapine. The remaining (n = 89; 20%) had received other antipsychotics. The two groups were comparable in socio-demographic and clinical characteristics of PDD. Compliance was good and comparable in both groups (> 80%, P = 0.2). Response to treatment was comparable in both groups (85% partial response and > 52% good response, all P > 0.3). Olanzapine was effective at lower mean chlorpromazine equivalents than risperidone (240 vs. 391, P < 0.05).ConclusionOur study indicates a good response to both risperidone and olanzapine, if compliance to treatment can be ensured. In the absence of specific treatment guidelines for PDD, second-generation antipsychotics like risperidone and olanzapine offer good treatment options for this infrequently encountered and difficult to treat psychiatric disorder.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
We report a new class of β-peptide based hydrogel for neural tissue engineering. Our β-peptide forms a network of nanofibres in aqueous solution, resulting in a stable hydrogel at physiological conditions. The hydrogel shows excellent compatibility with neural cells and provides a suitable environment for cells to adhere and proliferate.
