Abstract
OBJECTIVES The role of neovascularisation in tendinopathy is still poorly understood, potentially due to technical limitations of conventional power Doppler ultrasound. This study aimed to investigate the association between contrast-enhanced ultrasound (CEUS) microvascular volume (MV), Victorian Institute of Sports Assessment-Achilles (VISA-A) scores and intrinsic Achilles tendon tenderness, as well as two different Power Doppler modes. DESIGN Cross-sectional study. METHODS 20 individuals with uni- or bilateral Achilles tendinopathy completed a VISA-A questionnaire, and underwent microvascular volume measurements of the Achilles tendon mid-portion using both conventional, ultrasensitive (SMI™) power Doppler ultrasound and CEUS. Intrinsic tendon tenderness was assessed with sensation detection threshold to extracorporeal shock waves (ESW). Linear Mixed Model analysis was used to determine the association between microvascular volume (MV), VISA-A, and ESW-detection threshold for both symptomatic and asymptomatic Achilles tendons. RESULTS There was a significant association between VISA-A and MV (B=-5.3, 95%CI=[-8.5; -2.0], P=0.0004), and between MV and symptom duration (B=-1.7, 95%CI=[-3.2; -5.0], P=0.023). No significant associations were found between power Doppler ultrasound and CEUS-based MV or between CEUS-based MV and ESW-detection threshold. In comparison with conventional power Doppler ultrasound, SMI™ showed on average similar detection capacity for neovessels in the mid-portion of the Achilles tendon, whilst being superior for detecting neovessels within Kager's fat pad (t=3.46, 95%CI=[0.27; 1.03], P<0.005). CONCLUSIONS Our results indicate that CEUS-based MV of the Achilles tendon is moderately associated with Achilles tendon symptoms. In accordance, CEUS-detected MV could be a novel target for treatment as it seems to be more sensitive than PDU and is correlated with symptoms.

Abstract
With more than 240 million people infected, hepatitis B virus (HBV) is a major health concern. The inability to mimic the complexity of the liver using cell lines and regular primary human hepatocyte (PHH) cultures pose significant limitations for studying host/pathogen interactions. Here, we describe a 3D microfluidic PHH system permissive to HBV infection, which can be maintained for at least 40 days. This system enables the recapitulation of all steps of the HBV life cycle, including the replication of patient-derived HBV and the maintenance of HBV cccDNA. We show that innate immune and cytokine responses following infection with HBV mimic those observed in HBV-infected patients, thus allowing the dissection of pathways important for immune evasion and validation of biomarkers. Additionally, we demonstrate that the co-culture of PHH with other non-parenchymal cells enables the identification of the cellular origin of immune effectors, thus providing a valuable preclinical platform for HBV research.

Abstract
AIM Low Anterior Resection Syndrome (LARS) following rectal cancer surgery impairs the patient's quality of life (QoL). Rectal Irrigation has been demonstrated to be effective for anterior resection syndrome but many surgeons do not suggest it as a treatment. This feasibility study aimed to explore treatment acceptability and the benefit of rectal irrigation in patients who developed LARS following an anterior resection for rectal cancer. METHODS This was a qualitative study, involving semi-structured interviews. Twenty-one patients diagnosed with LARS following anterior resection for rectal cancer in a single tertiary centre were offered rectal irrigation as a treatment option. Qualitative interviews (n=17) were conducted at baseline to explore patient reported impact of LARS on QoL, treatment acceptability and factors influencing the decision to accept/decline treatment. Follow up interviews were carried out at six months for the treatment group only (n=12), to assess its practicality and impact on QoL. RESULTS Qualitative interview findings suggest rectal irrigation is an acceptable method of treatment for LARS. Participants who perceived their symptoms to be more severe or poorly controlled were most likely to consider rectal irrigation as a treatment option. The patients who completed treatment reported improvements in their QoL, the ability to control the time of defaecation being the key benefit CONCLUSION: Clinicians should consider offering rectal irrigation as a treatment option to patients presenting with bowel dysfunction following anterior resection as it can improve symptoms. Patients who perceive that their symptoms are severe are more likely to consider treatment. This article is protected by copyright. All rights reserved.

Abstract
AIM In the short term, continuous subcutaneous insulin infusion (CSII) has been associated with improved glycaemic control, reduced hypoglycaemia and improved quality of life (QOL). However, limited data are available on its long-term benefits, particularly in the UK. We aimed to assess the impact of CSII on longer term outcomes. METHOD Patient-level data were obtained for CSII users at Derby Teaching Hospitals, UK. Patient confidence and satisfaction questionnaires using the Likert scale were used to assess confidence in self-management. Comparative statistics were conducted using Pearson's chi-square and Student's t-tests. RESULTS Some 258 CSII users were identified (60.1% female, mean age 43.9 ± 13.4 years). Overall, there was significant decrease in HbA1c from 78 mmol/mol (9.3 ± 2.0%) at baseline, to 69 mmol/mol (8.5 ± 1.3%) at 6 months [mean difference (md): -0.64; 95% confidence interval (95% CI): -0.91 to -0.37; P < 0.0001]; which was sustained at 6 years of follow-up (HbA1c : 66 mmol/mol, 8.2 ± 1.3%; md: -1.07%; 95% CI: -1.45 to -0.69; P < 0.0001). One hundred and twenty-one patients (47%) responded to the survey, of whom 95 (78.5%) reported a reduction in the frequency of hypoglycaemia; 102 (84.3%) were satisfied with the quality of care received in the insulin pump service. CONCLUSION CSII therapy led to a sustained long-term improvement in glycaemic control in addition to a reduction in self-reported hypoglycaemia.

Abstract
BACKGROUND Osteogenesis imperfecta (OI), the commonest inherited bone fragility disorder, affects 1 in 15,000 live births resulting in frequent fractures and reduced mobility, with significant impact on quality of life. Early diagnosis is important, as therapeutic advances can lead to improved clinical outcome and patient benefit. REPORT Whole exome sequencing in patients with OI identified, in two patients with a multi-system phenotype, compound heterozygous variants in NBAS (neuroblastoma amplified sequence). Patient 1: NBAS c.5741G>A p.(Arg1914His); c.3010C>T p.(Arg1004*) in a 10-year old boy with significant short stature, bone fragility requiring treatment with bisphosphonates, developmental delay and immunodeficiency. Patient 2: NBAS c.5741G>A p.(Arg1914His); c.2032C>T p.(Gln678*) in a 5-year old boy with similar presenting features, bone fragility, mild developmental delay, abnormal liver function tests and immunodeficiency. DISCUSSION Homozygous missense NBAS variants cause SOPH syndrome (short stature; optic atrophy; Pelger-Huet anomaly), the same missense variant was found in our patients on one allele and a nonsense variant in the other allele. Recent literature suggests a multi-system phenotype. In this study, patient fibroblasts have shown reduced collagen expression, compared to control cells and RNAseq studies, in bone cells show that NBAS is expressed in osteoblasts and osteocytes of rodents and primates. These findings provide proof-of-concept that NBAS mutations have mechanistic effects in bone, and that NBAS variants are a novel cause of bone fragility, which is distinguishable from 'Classical' OI. CONCLUSIONS Here we report on variants in NBAS, as a cause of bone fragility in humans, and expand the phenotypic spectrum associated with NBAS. We explore the mechanism underlying NBAS and the striking skeletal phenotype in our patients.

Abstract
The world’s population is ageing. A significant proportion of this ageing population will undertake exercise, to optimise their health and wellbeing. Age-related changes in muscle physiology and composition may increase susceptibility to muscle injury and reduce the ability for recovery post exercise, which may have public health implications in years to come. This is a case report of a 59-year-old man with an isolated intramuscular haematoma, with onset during non-impact exercise (surfing and subsequently cricket). Injury to the latissimus dorsi muscle and/or tendon is rare. The individual in this report suffered from rheumatoid arthritis, which was well-controlled with methotrexate but had no other relevant medical history, which may have predisposed him to this injury.
