Abstract
BACKGROUND Osteoporosis is an age-related condition that can lead to fragility fractures and other serious consequences. The literature data on the impact of obesity on bone health are contradictory. The main reasons for this discrepancy could be the imperfect nature of the body mass index (BMI) as a marker of obesity, the metabolic status (inflammation and metabolically healthy obesity), and/or heterogeneity in bone variables and architecture or sex. AIMS To examine the relationship between bone variables and three validated obesity criteria. METHODS In this cross-sectional study, participants were classified as obese according to their BMI, waist circumference (WC), and fat mass (FM). Bone variables and architecture were assessed using dual-energy X-ray absorptiometry and peripheral quantitative computed tomography, respectively. RESULTS One hundred sixty-eight adults aged 55 or over (men: 68%) were included. 48 (28%) participants were obese according to the BMI, with 108 (64%) according to the FM, and 146 (87%) according to the WC. Bone variables were positively correlated with WC and BMI (Pearson's r = 0.2-0.42). In men only, the obesity measures were negatively correlated with cortical bone density (Pearson's r = - 0.32 to - 0.19) and positively correlated with cortical bone area (Pearson's r = 0.22-0.39). CONCLUSION Our findings indicate that independent of sex and obesity criteria, when significant, being obese seems to lead to higher bone parameters than being non-obese, except for cortical bone density. Thus, in the obese population, assessing cortical density might help the physician to identify bone alteration. Further researches are needed to confirm our findings.

Abstract
INTRODUCTION Tau pathology is a major age-related event in Down syndrome with Alzheimer's disease (DS-AD). Although recently, several different Tau PET tracers have been developed as biomarkers for AD, these tracers showed different binding properties in Alzheimer disease and other non-AD tauopathies. They have not been yet investigated in tissue obtained postmortem for DS-AD cases. Here, we evaluated the binding characteristics of two Tau PET tracers (3H-MK6240 and 3H-THK5117) and one amyloid (3H-PIB) ligand in the medial frontal gyrus (MFG) and hippocampus (HIPP) in tissue from adults with DS-AD and DS cases with mild cognitive impairment (MCI) compared to sporadic AD. METHODS Tau and amyloid autoradiography were performed on paraffin-embedded sections. To confirm respective ligand targets, adjacent sections were immunoreacted for phospho-Tau (AT8) and stained for amyloid staining using Amylo-Glo. RESULTS The two Tau tracers showed a significant correlation with each other and with AT8, suggesting that both tracers were binding to Tau deposits. 3H-MK6240 Tau binding correlated with AT8 immunostaining but to a lesser degree than the 3H-THK5117 tracer, suggesting differences in binding sites between the two Tau tracers. 3H-THK5117, 3H-MK6240 and 3H-PIB displayed dense laminar binding in the HIPP and MFG in adult DS brains. A regional difference in Tau binding between adult DS and AD was observed suggesting differential regional Tau deposition in adult DS compared to AD, with higher THK binding density in the MFG in adult with DS compared to AD. No significant correlation was found between 3H-PIB and Amylo-Glo staining in adult DS brains suggesting that the amyloid PIB tracer binds to additional sites. CONCLUSIONS This study provides new insights into the regional binding distribution of a first-generation and a second-generation Tau tracer in limbic and neocortical regions in adults with DS, as well as regional differences in Tau binding in adult with DS vs. those with AD. These findings provide new information about the binding properties of two Tau radiotracers for the detection of Tau pathology in adults with DS in vivo and provide valuable data regarding Tau vs. amyloid binding in adult DS compared to AD.

Abstract
INTRODUCTION Malnutrition increases postoperative morbidity and mortality. The objective of this study was to evaluate preoperative refeeding in malnourished patients at risk of refeeding syndrome (RS). METHODOLOGY A retrospective study, conducted between June 2016 and January 2017, reported to the CNIL, compared two groups of malnourished patients: a group of refeeding patients (RP) and a group of non-refeeding patients (NRP). The inclusion criteria were weight loss of more than 10% or albuminemia less than 35g/L and RS risk factor. The primary endpoint was postoperative morbidity. The secondary endpoints were weight change and serum albumin over 6 months. RESULTS Seventy-three patients (30 RP and 43 NRP) were included. At the time of initial management, median weight loss was 18% [1-71], while albuminemia was 26g/L [13-40] in the RP group and 32.5g/L [32-48] in the NRP group (P=0.01). The overall postoperative morbidity rate was 88% (83% RP versus 90% NRP, P=0.47), and there was no significant difference between the 2 groups. The rate of anastomotic complications was 4% for RP versus 26% for NRP (P=0.03) after exclusion of liver surgery. Medium-term weight loss tended to be greater in RP (P=0.7). Nutritional support was continued until the third postoperative month in 13% of RPs vs. no NRPs (P=0.0002). CONCLUSION After preoperative renutrition, we did not observe a decrease in morbidity but rather a decrease in the rate of anastomotic complications in favor of the RP group. This study underscores the middle-term importance of nutritional management in view of preserving the benefits of preoperative renutrition.

Abstract
L’hyperkaliémie est l’un des désordres hydroélectrolytiques les plus fréquemment rencontrés aux urgences. Les étiologies principales sont l’insuffisance rénale aiguë ou chronique, le diabète et l’insuffisance cardiaque. L’hyperkaliémie aiguë peut être une urgence vitale, car elle est potentiellement létale du fait du risque d’arythmie cardiaque. Sa prise en charge aux urgences manque actuellement de recommandations claires en ce qui concerne le seuil d’intervention et les thérapeutiques à utiliser. Les thérapeutiques couramment appliquées sont fondées sur un faible niveau de preuve, et leurs effets secondaires sont mal connus. Des études supplémentaires sont nécessaires pour évaluer l’utilisation de ces traitements et celle de nouveaux traitements potentiellement prometteurs. Nous faisons ici une mise au point sur les données connues en termes d’épidémiologie, de manifestations cliniques et électrocardiographiques, et des différentes thérapeutiques qui peuvent être proposées dans la prise en charge de l’hyperkaliémie aux urgences.

Abstract
OBJECTIVE Prospective assessment of the management of urinary tract infections (UTI) in the nursing homes of the Hauts-de-France region. PATIENTS AND METHODS A 50-question form had to be filled in for up to five consecutive residents treated for UTI in each nursing home. If necessary, diagnoses were reclassified according to the 2014 French Infectious Diseases Society guidelines. Analyses were presented per supposed (reported) and reclassified diagnoses. RESULTS Of 397 contacted facilities, 134 participated and informed 444 UTI episodes. Reported diagnostic criteria were burning urination (32%), malodorous urine (29%), confusion (28%), and turbid urine (19%). Twenty-one percent of diagnoses were based on erroneous criteria. Less than 50% of residents had a urine dipstick test performed and 94% a urine culture. The main pathogen was Escherichia coli. Reported indications were uncomplicated cystitis (32%), unspecified UTI (26%), complicated cystitis (9%), while no reason was given in 25% of cases. Only 10% of diagnoses were consistent with the guidelines: complicated cystitis (49%), asymptomatic bacteriuria (21%), acute pyelonephritis (21%), male UTI (9%). Almost 85% of prescriptions were active on the isolated bacteria. The empirical antibiotic therapy was consistent with the diagnosis in 16% of cases (30% for reclassified diagnoses). The two most prescribed antibiotic classes were fluoroquinolones (22.1%) and oral third-generation cephalosporins (19.1%). Only two of 157 possible de-escalations were performed. Duration of treatment was adequate for 19% of UTIs (9.6% of reclassified cases). CONCLUSION Our study revealed multiple deficiencies in diagnosis, antibiotic choice, treatment duration, and reevaluation.

Abstract
Family history is the major risk factor in the aetiology of breast cancer. Breast screening is currently available to women from the age of 50 to 64 through the National Breast Screening Programme. There is, however, an equivalent risk of developing breast cancer below 50 for first degree relatives of women diagnosed with breast cancer premenopausally. We have estimated the risk of breast cancer for relatives of women affected at different ages and used these to establish a family cancer clinic offering breast screening based on individual risk. In three years we have seen 851 patients. Compliance for annual radiology was in excess of 83% over this period and of five cancers detected one had a lump at presentation, two developed interval breast lumps, and two were asymptomatic.

Abstract
Activating mutations of the ras oncogene family occur at high frequency in all stages of thyroid tumorigenesis, both human and experimental. To test the causal nature of this association, and to investigate the biological role of ras mutation, we introduced a mutant c-Ha-ras gene into normal rat thyroid follicular cells using an ecotropic retroviral vector. The major immediate effect was to greatly extend the proliferative lifespan of these cells in culture from less than 3 to more than 15 doublings, without any observable loss of growth-factor dependence or differentiated functions. This in vitro phenotype strongly supports an initiating role for ras mutation in the genesis of benign thyroid tumors (adenomas) in vivo. Spontaneous transformation was observed at low frequency on continuous culture of mutant ras-expressing cells, giving rise to fully immortalized, growth factor-independent, highly tumorigenic lines. Transformation was associated with (i) loss of responsiveness to the growth inhibitor TGF-beta 1, and (ii) greatly increased nuclear levels of p53 protein, which unexpectedly was not due to point mutation in the conserved regions of the p53-coding sequence. We postulate that these two phenomena are causally related to each other and to the transformed phenotype.

A recombinant murine retroviral vector encoding the SV40 virus large T antigen was used to infect stably an immortal line of differentiated rat thyroid epithelial cells, FRTL-5. Expression of SV40 T transformed these cells to anchorage independence and tumorigenicity but did not alter morphology or abolish tissue-specific functions and growth factor requirements. The resulting phenotype provides a model of well-differentiated human thyroid cancer.

Abstract
A six year retrospective survey of enterococcal urinary tract infections in hospital inpatients is reported. During the study period there was an increase in the proportion of significant cultures that yielded enterococci. These organisms were more frequently isolated from catheter specimens than midstream specimens of urine and from surgical than from medical wards.
