Abstract
BACKGROUND Thyroid nodules (TN) are detected in a small number of asymptomatic children and adolescents but are more frequently malignant (22-26%) than in adults leading some clinicians to perform thyroid ultrasound (US) for all children with goiter or autoimmune thyroiditis (AIT). Our study was designed to determine if suspicious clinical features predict the presence of TN in children with goiter or AIT so that US could be performed on those at highest risk. METHODS This was a retrospective review of 223 children and adolescents with goiter or AIT evaluated at a single institution. US was not performed on all patients. It is our practice to define glands that are large, firm, or nodular to palpation as "suspicious". Suspicious glands were interrogated by US and if TN was confirmed, this was further evaluated by fine-needle aspiration followed by surgery if indicated. RESULTS The median age was 12.9 years with 74.4% female. TN were confirmed by US in 16.6% of all patients but only 4.8% of those with AIT. By univariate analysis, TN were more common in those with family history of TN or differentiated thyroid carcinoma (DTC), thyroid asymmetry, and lower thyrotropin (TSH) levels. Differentiated thyroid carcinoma (DTC) was identified in 10.8% of TN and 1.8% of all patients. Firmness was significantly more common in patients with DTC (p = 0.0013). CONCLUSION TN were less common in those with AIT than reported in previous studies, suggesting that clinical features might fail to identify the majority of TN in patients with AIT. However, patients with asymmetric thyroid and a family history of TN or DTC have greatest risk for TN.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
PURPOSE The aim was to review the use of The Over-volunteering Prevention System (TOPS) since the HRA began hosting it in 2013, and the Medicines and Healthcare products Regulatory Agency (MHRA) experience of monitoring its use by UK clinical research units. METHODS The HRA searched the TOPS database for the number, type and location of units and the number of entries. The MHRA inspectors reviewed their findings from routine inspections. RESULTS Twenty-two additional UK units registered to use TOPS during 2013-2016, making a total of 84 units since TOPS was established in 2002. Use of TOPS is now a condition of research ethics committee approval of a phase 1 study and fulfils MHRA accreditation requirements for preventing over-volunteering. The total number of entries by all active units during 2013-2016 was 89,335, of which 84% were UK citizens and 16% non-UK citizens. The total number of entries during 2002-2016 was 249,612. Only 15 of 24,531 subjects (1/1600) and 18 of 18,745 subjects (1/1040) entered in 2015 and 2016, respectively, were deemed potential over-volunteers. CONCLUSIONS The findings continue to support the concept that TOPS not only helps to prevent over-volunteering, but also deters subjects from trying to do so. Regulation of TOPS by the HRA and MHRA has enhanced its effectiveness, benefited all users and helped to improve the safety of volunteers who participate in non-therapeutic trials in the UK. The UK is still the only country with a national database to prevent over-volunteering that has published data on its widespread use and effectiveness.

Abstract
Recent statistics show that children exhibiting Attention Deficit Hyperactivity Disorder (ADHD) represent a significant number of school-based referrals for psychoeducational assessment and intervention. Despite the pervasiveness and salience of this disorder, educators continue to labor under a number of misconceptions about the nature of ADHD and what constitutes appropriate school-based assessment and intervention practice. In this article, common myths with regard to conceptual issues and assessment and intervention strategies are generated and responded to with practical research-based information.

Abstract
AIM Cholangiopancreatoscopy (CP) is an endoscopic technique that allows for direct visualization of the biliary and pancreatic ducts using a narrow caliber endoscope that passes through the working channel of a duodenoscope directly into the bile and/or pancreatic ducts. Little data is available on the safety of CP. We performed a multicenter retrospective study to evaluate the frequency and severity of adverse events with single operator CP. METHODS A multicenter retrospective study was conducted. RESULTS A total of 282 single operator peroral CP procedures were performed in 224 patients (128 M, 96 F). Most procedures involved the performance of therapeutic maneuvers, with most cases including multiple therapeutic maneuvers. Cholangioscopic or pancreatoscopic-assisted tissue sampling was performed in 222 procedures. Thirty-seven patients underwent electrohydraulic lithotripsy (EHL) for the treatment of common bile duct stones. Adverse events in patients undergoing single cholangioscopy and pancreatoscopy included post-ERCP pancreatitis (N.=11, 3.9%, all mild), post-ERCP cholangitis (N.=4, 1.4%), bleeding (N.=3, 1%), and perforation (N.=2, 0.7%). CONCLUSION Overall, our data shows that ERCP performed with single operator cholangioscopy or pancreatoscopy is safe with adverse events similar to that seen in large studies of ERCP performed without these additional techniques. Of note, vigorous irrigation of the bile ducts was not associated with increased rates of post-procedure cholangitis in our study.

Abstract
Background: Brain volume loss occurs in patients with relapsing–remitting MS. Fingolimod reduced brain volume loss in three phase 3 studies. Objective: To evaluate whether the effect of fingolimod on disability progression was mediated by its effects on MRI lesions, relapses or brain volume loss, and the extent of this effect. Methods: Patients (992/1272; 78%) from the FTY720 Research Evaluating Effects of Daily Oral Therapy in Multiple Sclerosis (FREEDOMS) study were analyzed. Month-24 percentage brain volume change, month-12 MRI-active lesions and relapse were assessed. The Prentice criteria were used to test surrogate marker validity. The proportion of treatment effect on disability progression explained by each marker was calculated. Results: Two-year disability progression was associated with active T2 lesions (OR = 1.24; p = 0.001) and more relapses during year 1 (OR = 2.90; p < 0.001) and lower percentage brain volume change over two years (OR = 0.78; p < 0.001). Treatment effect on active T2 lesions, relapses and percentage brain volume change explained 46%, 60% and 23% of the fingolimod effect on disability. Multivariate analysis showed the number of relapses during year 1 (OR = 2.62; p < 0.001) and yearly percentage brain volume change over two years (OR = 0.85; p = 0.009) were independent predictors of disability progression, together explaining 73% of fingolimod effect on disability. Conclusions: The treatment effect on relapses and, to a lesser extent, brain volume loss were both predictors of treatment effect on disability; combining these predictors better explained the effect on disability than either factor alone.

Abstract
Isolated spontaneous dissecting aneurysm of celiac artery without concomitant involvement of aorta is a rare entity and only a few cases are reported in the literature. More cases are being detected recently with greater advancements in CT technology. Clinicians and emergency physicians should be aware of this condition and should include it in the differential diagnosis of patients who present with refractory postprandial epigastric pain, particularly in middle-aged men. We present a case of a 45-year-old male with isolated spontaneous dissecting celiac artery aneurysm, with special emphasis on CT findings and the role of endovascular management.

Abstract
Abstract
We undertook a prospective quality assurance and metric study in 26 women with early breast cancer (EBC) in order to identify issues that may interfere with real-time integration of massive parallel sequencing (MPS) with clinical and pathology parameters for clinical decision making.
Pre-operatively, patients underwent formal informed consent process with the aid of bespoke multimedia (iPad) technology to educate patients on a) the logistical aims of the trial b) somatic and hereditary genomics c) privacy and off target (non-cancer) issues.
On Day 1, seven patients (27%) underwent WLE & SNB, 17 (65%) WLE & AXLND, 2 (7%) Mastectomy & SNB.
Samples (tumour and normal) were collected fresh into Qiagen PaxGene Tissue Container preserving both morphology and biomolecules of the sample with lysis of tissues overnight.
Day 2&3; DNA extraction was performed using the Qiagen DSP kit over 1 hour.
DNA MPS CCP was performed on Life technologies Proton P1 chip using in-house modification of manufacturers protocol. The average time taken to run CCP includes 2 days library preparation; 4 hour sequencing run, 8 hours primary analysis for generating read alignments and sequencing files. The Ampliseq protocol required modifications with respect to template input amount and cycling parameters in order to increase the fidelity of library preparation. Limitations in sequencing depth and read qualities with the current technologies lend themselves to approximately 5-6 samples/sequencing run/day if 500x read depth per amplicon is desired.
Days 4-6 manually curated bioinformatics against publicly available mutation databases (e.g. COSMIC, ENSEMBL etc.)
Day 7 communication of results
Molecular Pathology results
The median age was 57, (32-84), 18 (72%) were postmenopausal. Histopathology invasive ductal 22 (84%), invasive lobular 2 (8%) metaplastic 2 (8%).

Abstract
BACKGROUND Reduction in peripheral blood lymphocytes is an expected pharmacodynamic outcome of fingolimod therapy. OBJECTIVE The objective of this article is to evaluate lymphocyte dynamics during and after fingolimod therapy and assess the relationship between lymphocyte counts and infections. METHODS Lymphocyte counts and their relationship with infections were evaluated in three multiple sclerosis (MS) populations: (Group A) FREEDOMS phase 3 core study group (n = 1272); (Group B) All Studies group (one phase 2 and two phase 3 studies, plus their extensions; n = 2315); and (Group C) Follow-up group (after fingolimod discontinuation; n = 538). RESULTS Administration of fingolimod 0.5 mg led to reductions in lymphocyte counts to a steady-state of 24%-30% of baseline values within two weeks, which remained stable while on therapy. Following fingolimod discontinuation, average counts exceeded the lower limit of normal range within six to eight weeks, and were 80% of baseline values by three months. In Group A, infection rates per patient-year were 1.4 with placebo and 1.0 in fingolimod-treated patients who had the lowest lymphocyte counts (< 0.2 × 10(9)/l). No evidence was seen for an increase in serious or opportunistic infections. CONCLUSIONS Fingolimod induces a rapid and reversible reduction in lymphocyte counts without an increase in infections relative to placebo. Because fingolimod reduces blood lymphocyte counts via redistribution in secondary lymphoid organs, peripheral blood lymphocyte counts cannot be utilized to evaluate the lymphocyte subset status of a patient.

Abstract
INTRODUCTION Anaemia is common in rheumatoid arthritis (RA). Clinicians may focus on rheumatological issues and assume anaemia of chronic disease (ACD). This study challenged this assumption and investigated the causes of anaemia in a large cohort of RA patients to assess its implications. METHODS The hospital where the study was conducted monitors regular full blood count and erythrocyte sedimentation rate (ESR) monthly in all RA patients on disease modifying drugs to assess efficacy and safety. A computerised system identifies and records abnormal results. The database for 2009 was interrogated to find all patients with two consecutive haemoglobin values <11 g/dl. Using a proforma, patients were defined as having iron deficiency anaemia (IDA), ACD, macrocytic anaemia (MCA) or another cause. All results of further tests investigating the anaemia were recorded. RESULTS Among 2000 RA patients on the system, 199 (10%) were identified as having anaemia over a year. Of these, 90 had IDA, 78 had ACD, 25 had MCA, and 6 had postoperative anaemia. Among 90 patients with IDA, investigations were performed in 53, with 23 normal. An explanation for IDA was found in 30: gastrointestinal bleeding in 25, gynaecological blood loss in 3, and urinary bleeding in 2. Among 78 patients with ACD, response to intensification of RA treatment occurred in 45, but erythropoietin therapy was required in 9. Within the 25 patients with MCA, 12 had unrecognised vitamin B(12) deficiency, 4 drug induced changes, 3 myeloid malignancy, 2 hypothyroidism, and 2 alcoholism. CONCLUSIONS Anaemia in RA is common, multifactorial, and potentially both serious and correctable. Established malignancy was present in 10 patients and premalignancy in a further 10 (10% of total). Treatable causes were commonly identified. Clinicians need to investigate the nature and cause of persistent anaemia, and must not assume it to be simply ACD without evidence.
