Abstract
OBJECTIVES HIV-associated neurocognitive disorders are highly prevalent, and physical activity (PA) is a modifiable behaviour that may affect neurocognitive function. Our objective was to determine the association between PA and neurocognitive function and the effect of HIV on this association. METHODS PA was assessed in the Multicenter AIDS Cohort Study with the International Physical Activity Questionnaire. A neuropsychological test battery assessed global impairment and domain-specific impairment (executive function, speed of processing, working memory, learning, memory, and motor function) every 2 years. Semiannually, the Symbol Digit Modalities Test and Trail Making Test Parts A and B were performed. Adjusted logistic regression models were used to assess the PA-neurocognitive function association. Using longitudinal data, we also assessed the PA category-decline of neurocognitive function association with multivariate simple regression. RESULTS Of 601 men, 44% were HIV-infected. Low, moderate, and high PA was reported in 27%, 25%, and 48% of the HIV-infected men vs. 19%, 32% and 49% of the HIV-uninfected men, respectively. High PA was associated with lower odds of impairment of learning, memory, and motor function [odds ratio (OR) ranging from 0.52 to 0.57; P < 0.05 for all]. The high PA-global impairment association OR was 0.63 [95% confidence interval (CI) 0.39, 1.02]. Among HIV-infected men only, across multiple domains, the high PA-impairment association was even more pronounced (OR from 0.27 to 0.49). Baseline high/moderate PA was not associated with decline of any domain score over time. HIV infection was marginally associated with a higher speed of decline in motor function. CONCLUSIONS A protective effect of high PA on impairment in neurocognitive domains was observed cross-sectionally. Longitudinal PA measurements are needed to elucidate the PA-neurocognitive function relationship over time.

Abstract
Although a cure still cannot be expected for metastatic breast cancer, thanks to progressive advances in treatments, life expectancy has been increasing over the past 15 years. This study aims to present the impact on the organisation of patients' management of newly released oral targeted therapies dedicated to metastatic breast cancer and the obstacles to their diffusion. Our work is based on the analysis of 40 semi-structured interviews, conducted with oncology healthcare professionals in three regions of France (2015-2016). It shows three main results. First, the prescription of an oral targeted therapy requires greater collaboration between healthcare professionals than traditional intravenous oncology drugs, which may be challenging. Second, there remain many barriers to the dissemination of oral targeted therapies. Third, taking an oral targeted therapy keeps the patient away from the hospital facility and asks for a strong therapeutic alliance. The management of oral targeted therapies is time-consuming for medical oncologists and disrupts the traditional care pathway. The multiplication of actors involved in patients' management reinforces the slowdown in the deployment and acceptance of therapeutic innovations. More players equal a higher risk of slowdown. Questioning and re-designing hospital organisation and management modalities towards this type of care are critical.

Abstract
Exposure to violence puts children at risk for developing a variety of problems, including depression, anxiety, and conduct problems. The extent to which children's individual, family, school, and peer group characteristics influence resilient responses to violence exposure was investigated amongst Grade 6 students living in a high-violence community in Cape Town. The majority (68.44%) reported both witnessing and being a victim of violence. Both witnessing and victimisation by violence were found to be positively associated with anxiety and depression, but only victimisation was positively associated with conduct problems. Peer delinquency was positively associated with both depression and conduct problems. Involvement in conventional after-school activities was negatively associated with anxiety, and school support was negatively associated with both depression and conduct problems. No association was identified between parent support and any of anxiety, depression, or conduct problems. However, this latter finding may be related to measurement problems, or to participants' reports that they were most likely to be victimised in their homes (rather than at school or in the neighbourhood). While this study is limited by its cross-sectional nature, it implies that key sites for intervention are after-school activities, school support, peer delinquency, and home life.

Abstract
Triple-negative breast cancer (TN), as defined by the triple negativity in immunohistochemistry: the absence of estrogen receptor, progesterone receptor and the absence of overexpression or amplification of HER2, corresponds to 15 % of invasive breast cancers. This is a very heterogeneous group of tumors both at the genomic and transcriptomic level and at morphological, clinical and prognostic level. Although there are some good prognosis forms, the majority of TN tumors is characterized by a poor prognosis with a greater frequency of visceral metastases and a maximum risk of relapse in the first two years after diagnosis. Systemic adjuvant treatment with chemotherapy is almost always indicated. The surgical treatment and radiotherapy treatment should be comparable to the other subtypes and obey the same rules of oncologic surgery. TN tumors are not associated with a higher risk of locoregional relapse after conservative treatment and adjuvant radiotherapy. Optimization of systemic therapies is currently and for the last decade a challenge. A number of targeted therapies and efficiency biomarkers identification of these targeted therapies is essential to allow significant progress in optimizing systemic therapy for these tumors.

Abstract
Abstract
BACKGROUND: Many children diagnosed with functional constipation (FC) in the ED in fact meet Rome III criteria for irritable bowel syndrome constipaion subtype (IBS-C). The frequency of this misdiagnosis and its relation to outcomes is unknown.
OBJECTIVES: To determine if treatment failure frequency differs based on Rome III diagnostic criteria classification in a cohort of ED children diagnosed by treating physicians as having constipation.
DESIGN/METHODS: We performed a prospective cohort study of children 1 month – 18 years of age who were diagnosed with or were treated as FC in a pediatric ED. ED chart data was abstracted and a follow-up call was performed 7 days post-ED visit to enable the completion of the ROME III functional intestinal disorder questionnaire, confirm treatments administered, and enable symptom resolution assessment. 'Adequate therapy' was defined in accordance with ESPGHAN/NASPGHAN consensus guidelines. Treatment failure was defined by ≥2 of the following: persistence of presenting symptom(s), bowel movement frequency <1 every other day, pain or difficulty passing stools, abdominal pain between bowel movements, and/or persistence of the ED chief complaint.
RESULTS: 929 potentially eligible children were identified; 237 were excluded. We failed to contact 162 patients and 17 refused consent. 513 (74%) completed day 7 follow up – 227 (44%) met FC ROME III criteria, 119 (23%) met IBS-C criteria and 167 (33%) did not meet IBS-C or FC criteria and were classified as ‘other’. Mean age was 6.1±3.9 years. Treatment failure occurred in 69 (30%) FC patients, 50 (43%) of those with IBS-C, and 41 (25%) of ‘other’ group; P=0.007. These differences persisted when only those receiving ‘adequate therapy’ (n=308) were included: 41 (28%) of FC and 16 (22%) of those in the ‘other’ group had persistent symptoms compared to 37 (43%) of IBS-C patients; P=0.008. Kaplan-Meier analysis revealed greater symptom persistence in children with IBS-C compared to those with FC (P<0.001). Those classified as FC were more likely to have abdominal distension (P=0.05) and tenderness (P=0.04) compared to the IBS-C.
CONCLUSION: Children diagnosed with constipation in an ED who fulfill ROME III irritable bowel syndrome (constipation subtype) criteria have a higher treatment failure rate at day 7 compared to functional constipation even when including only those who received adequate functinal constipation therapy. ROME III criteria can be employed to identify children with irritable bowel syndrome; such children might benefit from diagnosis specific therapy.

Abstract
EBV-associated post-transplant lymphoproliferative disease (PTLD) remains an important complication of allogeneic haematopoietic stem cell transplantation (allo-HSCT). We retrospectively analysed the incidence and risk factors for EBV reactivation in 186 adult patients undergoing consecutive allo-HSCT with alemtuzumab T-cell depletion at a single centre. The cumulative incidence of EBV reactivation was 48% (confidence interval (CI) 41-55%) by 1 year, with an incidence of high-level EBV reactivation of 18% (CI 13-24%); 8 patients were concurrently diagnosed with PTLD. Amongst patients with high-level reactivation 31/38 (82%) developed this within only 2 weeks of first EBV qPCR positivity. In univariate analysis age⩾50 years was associated with significantly increased risk of EBV reactivation (hazard ratio (HR) 1.54, CI 1.02-2.31; P=0.039). Furthermore, a diagnosis of non-Hodgkin lymphoma (NHL) was associated with greatly reduced risk of reactivation (HR 0.10, CI 0.03-0.33; P=0.0001) and this was confirmed in multivariate testing. Importantly, rituximab therapy within 6 months prior to allo-HSCT was also highly predictive for lack of EBV reactivation (HR 0.18, CI 0.07-0.48; P=0.001) although confounding with NHL was apparent. Our data emphasise the risk of PTLD associated with alemtuzumab. Furthermore, we report the clinically important observation that rituximab, administered in the peri-transplant period, may provide effective prophylaxis for PTLD.

Abstract
The yeast Wickerhamomyces anomalus has been studied for its wide biotechnological potential, mainly for applications in the food industry. Different strains of W. anomalus have been isolated from diverse habitats and recently from insects, including mosquitoes of medical importance. This paper reports the isolation and phylogenetic characterization of W. anomalus from laboratory-reared adults and larvae of Phlebotomus perniciosus (Diptera: Psychodidae), a main phlebotomine vector of human and canine leishmaniasis. Of 65 yeast strains isolated from P. perniciosus, 15 strains were identified as W. anomalus; one of these was tested for the killer phenotype and demonstrated inhibitory activity against four yeast sensitive strains, as reported for mosquito-isolated strains. The association between P. perniciosus and W. anomalus deserves further investigation in order to explore the possibility that this yeast may exert inhibitory/killing activity against Leishmania spp.

Abstract
Moyamoya disease (MMD) is a progressive vasculopathy characterized by occlusion of the terminal portion of the internal carotid arteries and its branches, and the formation of compensatory moyamoya collateral vessels. Homozygous mutations in GUCY1A3 have been reported as a cause of MMD and achalasia. Probands (n = 96) from unrelated families underwent sequencing of GUCY1A3. Functional studies were performed to confirm the pathogenicity of identified GUCY1A3 variants. Two affected individuals from the unrelated families were found to have compound heterozygous mutations in GUCY1A3. MM041 was diagnosed with achalasia at 4 years of age, hypertension and MMD at 18 years of age. MM149 was diagnosed with MMD and hypertension at the age of 20 months. Both individuals carry one allele that is predicted to lead to haploinsufficiency and a second allele that is predicted to produce a mutated protein. Biochemical studies of one of these alleles, GUCY1A3 Cys517Tyr, showed that the mutant protein (a subunit of soluble guanylate cyclase) has a significantly blunted signaling response with exposure to nitric oxide (NO). GUCY1A3 missense and haploinsufficiency mutations disrupt NO signaling leading to MMD and hypertension, with or without achalasia.

Abstract
BACKGROUND/AIMS C-peptide allows estimation of insulin secretion even in the presence of insulin treatment. C-peptide may be suitable for the differential diagnosis of type 1 and type 2 diabetes, and, within type 2 diabetes, of insulin-requiring vs. non-insulin-requiring patients. Relating C-peptide concentrations to ambient glucose levels might improve its diagnostic potential. PATIENTS/METHODS The diagnostic value (a) fasting C-peptide, (b) C-peptide/glucose ratios, and (c) the HOMA-ßC-peptide-index for predicting a diagnosis of type 1 (vs. type 2) diabetes were assessed. SETTING Specialised hospital for the care of diabetic patients (inpatient treatment). 303 patients with type 1 diabetes and 841 patients with type 2 diabetes. MAIN OUTCOME MEASURE Odds ratios and 95% confidence intervals for a clinical diagnosis of type 1 diabetes or for insulin treatment by deciles of (a) fasting C-peptide, (b) C-peptide/glucose ratios, and (c) HOMA-ßC-peptide-index. RESULTS Low C-peptide concentrations were associated with a high odds ratio for type 1 diabetes and vice versa (p<0.0001). Concentrations of 0.13-0.36 nmol/l did not discriminate. C-peptide/glucose ratios or HOMA-ßC-Peptide did not perform better. The ability of all 3 parameters to predict the necessity for insulin treatment within the population of type 2-diabetic patients was low. CONCLUSIONS Fasting C-peptide and derived parameters help to differentiate type 1 from type 2 diabetes, but there is a range of C-peptide concentrations that does not help discriminate. Relating C-peptide to glucose did not improve diagnostic accuracy. C-peptide does not help predicting a need for insulin treatment in patients with type 2 diabetes.

Abstract
INTRODUCTION Workers in aluminium production are exposed to a complex mixture of particles and gases potentially harmful to the airways, among them aluminium oxide (Al2O3). With the use of an exposure chamber, we aimed to examine the effects of short-term controlled exposure to Al2O3 on lung function and inflammatory markers in healthy volunteers. METHODS 15 men (age 19-31) were exposed in random order to clean air or Al2O3 particles (3.8-4.0 mg/m(3)) for 2 h including 30 min exercise (stationary bike, 75 W). The permissible exposure level (PEL) for Al2O3 by Occupational Safety and Health Administration, USA, is 5 mg/m(3) time weighted average (TWA). Sham and particle exposures were separated by at least 2 weeks. Spirometry was carried out, and induced sputum and blood samples were collected 48 h before and 4 and 24 h after exposure. RESULTS Levels of sputum neutrophils (mean (±SEM)) was increased 24 h post-Al2O3 vs pre-Al2O3 exposure (43% (4) vs 31% (4), p=0.01) and the protein level of interleukin (IL)-8 had a 4.8 (0.9)-fold change increase 24 h after exposure (p<0.01). Following Al2O3 exposure, gene signatures in sputum were significantly increased related to several pathways. CONCLUSIONS The present study suggests that controlled exposure to Al2O3 particles at levels below PEL (TWA) induces airway inflammation in healthy humans marked by elevated neutrophils and elevated IL-8. In addition, increased expression of genes associated with several biological processes was observed in sputum. Interestingly, inhaled Al2O3-induced effects were localised to the airways and not systemic.

Abstract
OBJECTIVE Controlling vaccine-preventable infectious diseases is a public health priority in French Guiana but there is currently no epidemiological data on pediatric bacterial meningitis in this overseas department. Our aim was to describe data related to pediatric bacterial meningitis in French Guiana and compare it with that of metropolitan France. METHODS We conducted a multicenter retrospective study from 2000 to 2010 to describe the clinical picture, biological data, epidemiology, and outcome of pediatric bacterial meningitis case patients in French Guiana. RESULTS The median age of bacterial meningitis patients was 6months [0-15] and the sex ratio 1.06. We observed a total of 60 bacterial meningitis case patients. Most presented with pneumococcal meningitis (24 patients; 40%); 11 with Haemophilus influenzae type b meningitis (23%), five with group B streptococcal meningitis (8.5%), and five others (8.5%) with staphylococcal meningitis (three patients presented with coagulase-negative staphylococci and two with Staphylococcus aureus). Only one patient presented with group B meningococcal meningitis, an 18-month-old infant. We recorded 14 deaths (overall case fatality: 23%); eight were due to Streptococcus pneumoniae (case fatality: 33%). The overall sequelae rate was 28%. It was 32% for patients presenting with pneumococcal meningitis. We observed that 38% of children who had never been vaccinated were infected by a vaccine-preventable bacterium. We observed many differences in the distribution of the bacteria and in the patients' prognosis when comparing the French Guiana data with that of metropolitan France. CONCLUSION Improving vaccination coverage would decrease the incidence of H. influenzae meningitis.

Abstract
While the neurobiological basis and developmental course of attention-deficit/hyperactivity disorder (ADHD) have not yet been fully established, an imbalance between inhibitory/excitatory neurotransmitters is thought to have an important role in the pathophysiology of ADHD. This study examined the changes in cerebral levels of GABA+, glutamate and glutamine in children and adults with ADHD using edited magnetic resonance spectroscopy. We studied 89 participants (16 children with ADHD, 19 control children, 16 adults with ADHD and 38 control adults) in a subcortical voxel (children and adults) and a frontal voxel (adults only). ADHD adults showed increased GABA+ levels relative to controls (P = 0.048), while ADHD children showed no difference in GABA+ in the subcortical voxel (P > 0.1), resulting in a significant age by disorder interaction (P = 0.026). Co-varying for age in an analysis of covariance model resulted in a nonsignificant age by disorder interaction (P = 0.06). Glutamine levels were increased in children with ADHD (P = 0.041), but there was no significant difference in adults (P > 0.1). Glutamate showed no difference between controls and ADHD patients but demonstrated a strong effect of age across both groups (P < 0.001). In conclusion, patients with ADHD show altered levels of GABA+ in a subcortical voxel which change with development. Further, we found increased glutamine levels in children with ADHD, but this difference normalized in adults. These observed imbalances in neurotransmitter levels are associated with ADHD symptomatology and lend new insight in the developmental trajectory and pathophysiology of ADHD.

Abstract
OBJECTIVE To assess toxicity profile in two stage-IB1 cervical cancer treatment strategies: surgery with and without preoperative uterovaginal pulsed dose-rate brachytherapy. METHODS A retrospective study included 45 patients presenting stage-IB1 cervical cancer without pelvic lymph-node invasion, between 2009 and 2011: 25 treated by colpohysterectomy alone (group A) and 20 with preoperative uterovaginal pulsed dose-rate brachytherapy (group B). The median follow-up was 45 and 39 months (group A and B). RESULTS Groups were comparable for age (median, 46.9 vs 47.6 years), histologic type (52% vs 65% squamous cell carcinoma) and tumor size (68% vs 60%, <2cm). In postoperative year 1, rates of urinary, digestive and gynaecological disorder were 39.1%, 8.7% and 15% respectively in group A versus 36.8%, 5.3% and 31.6% in group B and in year 2, 5.9%, 8.4% and 15% versus 5.6%, 5.1% and 27.8%. DISCUSSION AND CONCLUSION The present study comparing two stage-IB1 cervical cancer treatment strategies found no significant difference in early or late complications. In 2 months, there was greater grade-3 urinary toxicity (21.1%) and sexual disorder (15.8%) with preoperative brachytherapy but no significant difference. Exclusive surgery is probably preferable for the patient's quality of life.

Abstract
We undertook a retrospective comparative study of all patients with an unstable slipped capital femoral epiphysis presenting to a single centre between 1998 and 2011. There were 45 patients (46 hips; mean age 12.6 years; 9 to 14); 16 hips underwent intracapsular cuneiform osteotomy and 30 underwent pinning in situ, with varying degrees of serendipitous reduction. No patient in the osteotomy group was lost to follow-up, which was undertaken at a mean of 28 months (11 to 48); four patients in the pinning in situ group were lost to follow-up, which occurred at a mean of 30 months (10 to 50). Avascular necrosis (AVN) occurred in four hips (25%) following osteotomy and in 11 (42%) following pinning in situ. AVN was not seen in five hips for which osteotomy was undertaken > 13 days after presentation. AVN occurred in four of ten (40%) hips undergoing emergency pinning in situ, compared with four of 15 (47%) undergoing non-emergency pinning. The rate of AVN was 67% (four of six) in those undergoing pinning on the second or third day after presentation. Pinning in situ following complete reduction led to AVN in four out of five cases (80%). In comparison, pinning in situ following incomplete reduction led to AVN in 7 of 21 cases (33%). The rate of development of AVN was significantly higher following pinning in situ with complete reduction than following intracapsular osteotomy (p = 0.048). Complete reduction was more frequent in those treated by emergency pinning and was strongly associated with AVN (p = 0.005). Non-emergency intracapsular osteotomy may have a protective effect on the epiphyseal vasculature and should be undertaken with a delay of at least two weeks. The place of emergency pinning in situ in these patients needs to be re-evaluated, possibly in favour of an emergency open procedure or delayed intracapsular osteotomy. Non-emergency pinning in situ should be undertaken after a delay of at least five days, with the greatest risk at two and three days after presentation. Intracapsular osteotomy should be undertaken after a delay of at least 14 days. In our experience, closed epiphyseal reduction is harmful. Cite this article: Bone Joint J 2015;97-B:412–19.

Abstract
BACKGROUND AND PURPOSE Fibrates are a class of drugs widely used to treat dyslipidaemias. They regulate lipid metabolism and act as PPARα agonists. Clinical trials demonstrate that besides changes in lipid profiles, fibrates decrease the incidence of cardiovascular events, with gemfibrozil exhibiting the most pronounced benefit. This study aims to characterize the effect of gemfibrozil on the activity and function of soluble guanylyl cyclase (sGC), the key mediator of NO signalling. EXPERIMENTAL APPROACH High-throughput screening of a drug library identified gemfibrozil as a direct sGC activator. Activation of sGC is unique to gemfibrozil and is not shared by other fibrates. KEY RESULTS Gemfibrozil activated purified sGC, induced endothelium-independent relaxation of aortic rings and inhibited platelet aggregation. Gemfibrozil-dependent activation was absent when the sGC haem domain was deleted, but was significantly enhanced when sGC haem was lacking or oxidized. Oxidation of sGC haem enhanced the vasoactive and anti-platelet effects of gemfibrozil. Gemfibrozil competed with the haem-independent sGC activators ataciguat and cinaciguat. Computational modelling predicted that gemfibrozil occupies the space of the haem group and interacts with residues crucial for haem stabilization. This is consistent with structure-activity data which revealed an absolute requirement for gemfibrozil's carboxyl group. CONCLUSIONS AND IMPLICATIONS These data suggest that in addition to altered lipid and lipoprotein state, the cardiovascular preventive benefits of gemfibrozil may derive from direct activation and protection of sGC function. A sGC-directed action may explain the more pronounced cardiovascular benefit of gemfibrozil observed over other fibrates and some of the described side effects of gemfibrozil.

Abstract
Brain glucose hypometabolism has been observed in Alzheimer’s disease (AD) patients, and is detected with 18F radiolabelled glucose, using positron emission tomography. A pathological hallmark of AD is deposition of brain β-amyloid plaques that may influence cerebral glucose metabolism. The five times familial AD (5XFAD) mouse is a model of brain amyloidosis exhibiting AD-like phenotypes. This study examines brain β-amyloid plaque deposition and 18FDG uptake, to search for an early biomarker distinguishing 5XFAD from wild-type mice. Thus, brain 18FDG uptake and plaque deposition was studied in these mice at age 2, 5 and 13 months. The 5XFAD mice demonstrated significantly reduced brain 18FDG uptake at 13 months relative to wild-type controls but not in younger mice, despite substantial β-amyloid plaque deposition. However, by comparing the ratio of uptake values for glucose in different regions in the same brain, 5XFAD mice could be distinguished from controls at age 2 months. This method of measuring altered glucose metabolism may represent an early biomarker for the progression of amyloid deposition in the brain. We conclude that brain 18FDG uptake can be a sensitive biomarker for early detection of abnormal metabolism in the 5XFAD mouse when alternative relative uptake values are utilized.

Abstract
OBJECTIVE Prolonged mechanical ventilation in the extremely premature infant is associated with the development of bronchopulmonary dysplasia (BPD). Clinically, the decision to extubate the extremely low birth weight (ELBW) infant can be difficult. There is continued debate regarding whether it is better for an ELBW infant to remain on the ventilator or to extubate to nasal constant positive airway pressure (nCPAP). It has also been argued that repeated intubations may be detrimental to ELBW infants. We tested the hypothesis that earlier extubation attempts would decrease length of hospital stay and BPD. STUDY DESIGN A database maintained on infants born at <27 completed weeks gestation admitted to our all referral NICU for a 36 month period was queried (n = 224). RESULTS Day of life (DOL) of the first extubation attempt was inversely correlated with birth weight (p < 0.001) and gestational age (p < 0.01). The DOL of the 1st extubation attempt correlated with the need for re-intubation (p < 0.001), but not with mortality (p = 0.27). In survivors, earlier DOL of 1st extubation attempt was associated with shorter LOS (p < 0.001). Earlier DOL of the 1st extubation attempt was associated with less need for supplemental oxygen (p < 0.001) at 36 weeks CGA, while re-intubation was not (p = 0.50). CONCLUSION In our cohort of extremely premature infants, the earlier the first extubation attempt the sooner the patient was discharged home and the less likely to develop BPD. Our study suggests that extubation should not be delayed in extremely premature infants due to fears of need for re-intubation.

Abstract
OBJECTIVE To describe and validate a novel, fully automated program specifically designed for the semiquantification of striatal (123)I-FP-CIT uptake using volumes of interest (VOI) analysis. MATERIAL AND METHODS The proposed algorithm is based on a template that mimics the striatal (123)I-FP-CIT uptake in a healthy subjects, derived from defined anatomical VOIs available from WFU PickAtlas. Four SPECT studies of the anthropomorphic Alderson phantom filled with variable radioactive concentrations were acquired for the experimental validation. Experimental SPECT images were spatially normalized with respect to the previously created template. The binary VOIs corresponding to left caudate and putamen and right caudate and putamen, which were used to construct the template, were projected onto the experimental images to obtain the counts for these regions. To minimize the partial volume effect, a percentage of the voxels in these regions (threshold), rather than all of them, was used. A binary occipital VOI was used to quantify the non-specific uptake. Experimental binding potentials (BPs) were calculated from the counts in these regions. True BPs were calculated from aliquots taken from the solutions used to fill the phantom. RESULTS There were statistically significant differences in the experimental BP values (p<0.002) according to the percentage of voxels used. A highly significant correlation was achieved between true and experimental BP values, regardless of the percentage of voxels included for quantification. CONCLUSIONS Our novel, observer-independent program automatically performs the semiquantification of striatal (123)I-FP-CIT uptake in experimental studies.

We report initial clinical features, surgical complications, ophthalmological outcome and clinical progression. RESULTS Twenty-nine eyes of 16 children met the inclusion criteria and were treated with trabeculotomy as first-line treatment (mean age: 6 months). Median follow-up was 7 years. No major perioperative complications occurred, but minor complications were observed in 11 eyes. Mean pre-operative and initial post-operative intraocular pressures were 25.4 and 9.1mmHg respectively, thus a decrease of 16.3 points (63%). Overall surgical success rate was 89% at first follow-up, 72% at one year and 64% on last follow-up. A mean intraocular pressure of 15mmHg on no medications was achieved for two-thirds of eyes. After 7 years of follow-up, over 50% of eyes did not require a 2nd surgery. Visual acuity was at least 20/30 for 62% of eyes (83% for eyes requiring only trabeculotomy). DISCUSSION AND CONCLUSION Trabeculotomy as first-line treatment of primary juvenile glaucoma is a safe and effective surgery in about two-thirds of cases. It allows pressure control and satisfactory visual outcome in the majority of children.

Abstract
Exploiting genotyping, DNA sequencing, imputation and trans-ancestral mapping, we used Bayesian and frequentist approaches to model the IRF5-TNPO3 locus association, now implicated in two immunotherapies and seven autoimmune diseases. Specifically, in systemic lupus erythematosus (SLE), we resolved separate associations in the IRF5 promoter (all ancestries) and with an extended European haplotype. We captured 3230 IRF5-TNPO3 high-quality, common variants across 5 ethnicities in 8395 SLE cases and 7367 controls. The genetic effect from the IRF5 promoter can be explained by any one of four variants in 5.7 kb (P-valuemeta = 6 × 10(-49); OR = 1.38-1.97). The second genetic effect spanned an 85.5-kb, 24-variant haplotype that included the genes IRF5 and TNPO3 (P-valuesEU = 10(-27)-10(-32), OR = 1.7-1.81). Many variants at the IRF5 locus with previously assigned biological function are not members of either final credible set of potential causal variants identified herein. In addition to the known biologically functional variants, we demonstrated that the risk allele of rs4728142, a variant in the promoter among the lowest frequentist probability and highest Bayesian posterior probability, was correlated with IRF5 expression and differentially binds the transcription factor ZBTB3. Our analytical strategy provides a novel framework for future studies aimed at dissecting etiological genetic effects. Finally, both SLE elements of the statistical model appear to operate in Sjögren's syndrome and systemic sclerosis whereas only the IRF5-TNPO3 gene-spanning haplotype is associated with primary biliary cirrhosis, demonstrating the nuance of similarity and difference in autoimmune disease risk mechanisms at IRF5-TNPO3.
