Abstract
BACKGROUND Extracellular fluid volume (ECF) is independently associated with chronic kidney disease (CKD) progression and mortality in patients with CKD, but the prognostic value of the trajectory of ECF over time beyond that of baseline value is unknown. OBJECTIVES To characterize ECF trajectory and evaluate its association with the risks of end-stage kidney disease (ESKD) and mortality. METHODS From the prospective tricentric NephroTest cohort, we included 1588 patients with baseline measured glomerular filtration rate (mGFR) ≥15 mL min-1 /1.73 m2 and ECF measurement. ECF and GFR were measured repeatedly using the distribution volume and clearance of 51 Cr-EDTA, respectively. ESKD and mortality were traced through record linkage with the national registries. Adjusted shared random-effect joint models were used to analyse the association between the trajectory of ECF over time and the two competing outcomes. RESULTS Patients were mean age 58.7 years, 66.7% men, mean mGFR of 43.6 ± 18.6 mL min-1 /1.73 m2 and mean ECF of 16.1 ± 3.6 L. Over a median follow-up of 5.3 [IQR: 3.0;7.4] years, ECF increased by 136 [95%CI 106;167] mL per year on average, whilst diuretic prescription and 24-hour urinary sodium excretion remained stable. ESKD occurred in 324 (20.4%) patients, and 185 (11.6%) patients died before ESKD. A higher current value of ECF was associated with increased hazards of ESKD (adjusted hazard ratio [aHR]: 1.12 [95%CI 1.06;1.18]; P < 0.001 per 1 L increase in ECF), and death before ESKD (aHR: 1.10 [95%CI 1.04;1.17]; P = 0.002). CONCLUSIONS The current value of ECF was associated with the risks of ESKD and mortality, independent of multiple potential confounders, including kidney function decline. This highlights the need for a close monitoring and adjustment of treatment to avoid fluid overload in CKD patients.

Abstract
The next generation of flexible, electrically active implants, such as brain implants or retina chips require a flexible, biostable as well as biocompatible passivation, ensuring a degradation-free usage for long time periods on the order of several years. Until today, these passivations are prepared mostly by polyimides or parylene, both of which are water vapor permeable to a certain degree. To remedy this deficiency, Atomic Layer Deposited (ALD) thin films are characterized regarding their electrical passivating features under conditions of accelerated aging, such as elevated temperatures in a liquid environment. The initial electrical passivation by various ALD deposited multilayers, combining alternating thin Al2O3 and TiO2 layers is the goal of this research as well as the stability of these layers under induced degradation. Such layers, in combination with a parylene passivation, would ensure a water vapor impermeable and biocompatible coating.

Abstract
AIM To describe current practices of glucose-lowering treatments in people with diabetes and chronic kidney disease (CKD), the associated glucose control and hypoglycaemic symptoms, with an emphasis on sex differences. METHODS Among the 3033 patients with CKD stages 3-5 recruited into the French CKD-REIN study, 645 men and 288 women had type 2 diabetes and were treated by glucose-lowering drugs. RESULTS Overall, 31% were treated only with insulin, 28% with combinations of insulin and another drug, 42% with non-insulin glucose-lowering drugs. In CKD stage 3, 40% of patients used metformin, 12% at stages 4&5, similar for men and women; in CKD stage 3, 53% used insulin, similar for men and women, but at stages 4&5, 59% of men and 77% of women used insulin. Patients were reasonably well controlled, with a median HbA1c of 7.1% (54mmol/mol) in men, 7.4% (57mmol/mol) in women (P=0.0003). Hypoglycaemic symptoms were reported by 40% of men and 59% of women; they were not associated with the estimated glomerular filtration rate, nor with albuminuria or with HbA1c in multivariable analyses, but they were more frequent in people treated with insulin, particularly with fast-acting and pre-mixed insulins. CONCLUSION Glucose-lowering treatment, HbA1c and hypoglycaemic symptoms were sex dependent. Metformin use was similar in men and women, but unexpectedly low in CKD stage 3; its use could be encouraged rather than resorting to insulin. Hypoglycaemic symptoms were frequent and need to be more closely monitored, with appropriate patient-education, especially in women.

Abstract
The induction of effective T cell-mediated immune responses is the main objective of vaccination against cancer. T cell responses are initiated by dendritic cells (DCs) as the most potent antigen-presenting cells. Designing vaccines for efficient delivery of tumor antigens to these cells in immunogenic fashion is, therefore, a major task in tumor immunology. In this human-based in vitro study we investigated the suitability of different polymeric nanoparticles (NPs) for delivering the tumor-associated antigen Her2/neu to DCs for induction of T cell responses by mucosal vaccination. The natural polymer chitosan and novel functionalized PLGA-based polymers were used for NP production. All NPs were efficiently taken up by DCs. Her2/neu delivered by NPs was more efficiently processed and presented by DCs than the soluble protein and induced more vigorous CD4+ and CD8+ T cell proliferation, and cytotoxic T cells. Testing the suitability of this platform for mucosal vaccination, NPs were applied to the apical side of an intestinal epithelium model and found to be efficiently transported across the epithelial layer to become available to basolateral DCs. Thus, chitosan and PLGA-based NPs are efficient carriers for delivery of antigens to DCs for induction of T cell-based immunity, and suitable for mucosal vaccine formulations.

Abstract
Identification of FDGavid- neoplasms may be obscured by high-uptake normal tissues, thus limiting inferences about the natural history of disease. We introduce a FDG-PET radiomics tissue classifier for differentiating FDGavid- normal tissues from tumor. Thirty-three scans from 15 patients with Hodgkin lymphoma and 68 scans from 23 patients with Ewing sarcoma treated on two prospective clinical trials were retrospectively analyzed. Disease volumes were manually segmented on FDG-PET and CT scans. Brain, heart, kidneys and bladder and tumor volumes were automatically segmented on PET images. Standard-uptake-value (SUV) derived shape and first order radiomics features were computed to build a random forest classifier. Manually segmented volumes were compared to automatically segmented tumor volumes. Classifier accuracy for normal tissues was 90%. Classifier performance was varied across normal tissue types (brain, left kidney and bladder, hear and right kidney were 100%, 96%, 97%, 83% and 87% respectively). Automatically segmented tumor volumes showed high concordance with the manually segmented tumor volumes (R2 = 0.97). Inclusion of texture-based radiomics features minimally contributed to classifier performance. Accurate normal tissue segmentation and classification facilitates accurate identification of FDGavid tissues and classification of those tissues as either tumor or normal tissue.

Abstract
ZusammenfassungEine indirekte Beurteilung der Mikroarchitektur (MA) ist in der täglichen Praxis anhand des TBS (Trabecular Bone Score) näherungsweise möglich. Das Ziel der OsteoLaus-Kohorte besteht darin, klinische Risikofaktoren und Informationen aus der DXA (Knochenmineraldichte [BMD], TBS und Wirbelkörperfrakturerkennung [VFA]) zu kombinieren, um Frauen mit hohem Frakturrisiko leichter zu erkennen. Wir nahmen 631 Frauen im mittleren Alter von 67,4 ± 6,7 J. und mit einem BMI von 26,1 ± 4,6 auf. Es bestand eine schwache Korrelation zwischen BMD und Zentrums-gematchtem TBS (r2 = 0,16). Die Prävalenz von Wirbelfrakturen (VFx) Grad 2/3, größeren osteoporotischen (OP) Frakturen und allen OP-Frakturen betrug 8,4 %, 17,0 % bzw. 26,0 %. Alters- und BMI-adjustierte OR (nach abnehmender SD) lagen bei 1,8 (1,2–2,5), 1,6 (1,2–2,1) bzw. 1,3 (1,1–1,6) für BMD und 2,0 (1,4–3,0), 1,9 (1,4–2,5) bzw. 1,4 (1,1–1,7) für TBS. Die TBS OR (nach abnehmender SD), adjustiert nach Alter, BMI und Wirbelsäulen-BMD, für VFx Grad 2/3, größere und alle OP-Frakturen betrugen 1,7 (1,1–2,7), 1,6 (1,2–2,2) bzw. 1,3 (1,0–1,7). Nur 35 bis 44 % der Frauen mit OP-Frakturen hatten eine BMD <−2,5 SD oder einen TBS < 1.200. Durch Kombination eines BMD < −2,5 SD oder TBS < 1,200 werden 54 bis 60 % der Frauen mit OP-Fraktur erkannt. Somit können wir anhand von VFA, BMD und TBS aus einem einfachen und strahlenarmen Röntgenverfahren, der DXA, Zusatzinformationen gewinnen, die für den Patienten im Praxisalltag von Nutzen sind.

Abstract
PURPOSE The study's purpose was to develop practical guidelines for assessment and management of refusal of treatment by adults afflicted with cancer. METHODS The French Association for Supportive Care in Cancer and the French Society for Psycho-oncology gathered a task force that applied a consensus methodology to draft guidelines studied predisposing situations, the diagnosis, regulatory aspects, and the management of refusal of treatment by adults afflicted with cancer. RESULTS We propose five guidelines: (1) be aware of the conditions/profiles of patients most often associated with refusal of treatment so as to adequately underpin the care and support measures; (2) understand the complexity of the process of refusal and knowing how to accurately identify the type and the modalities of the refused treatments; (3) apply a way to systematically analyze refusal, thereby promoting progression from a situation of disaccord toward a consensual decision; (4) devise procedures, according to the legal context, to address refusal of treatment that safeguards the stakeholders in situations of sustained disaccord; and (5) know the indications for ethical collective decision-making. CONCLUSION The quality of the relationship between patients and health professionals, and the communication between them are essential components involved in reaching a point of consent or refusal of treatment. A process of systematic analysis of refusal is recommended as the only way to ensure that all of the physiological, psychological, and contextual elements that are potentially involved are taken into account.

Abstract
UNLABELLED We evaluated the influence of degenerative disease and fractured vertebra on lumbar spine bone mineral density (BMD) and trabecular bone score (TBS) in 1500 women aged 50-80 years. TBS was not affected by a degenerative disease. While BMD increases after 62.5 years, TBS continues to decline. TBS should play a leading role in lumbar spine evaluation. INTRODUCTION After menopause, lumbar spine (LS) BMD and TBS values decrease. Degenerative disease (DD) increases with age and affect LS BMD. The aim of this study was to measure changes in LS BMD and TBS in women 50 to 80 years old, taking into account the impact of fractured vertebrae and DD. METHODS LS BMD, TBS, and vertebral fracture assessment were evaluated in the OsteoLaus cohort (1500 women, 50-80 years old). The exams were analyzed following ISCD guidelines to identify vertebrae with fractures or DD (Vex). RESULTS 1443 women were enrolled: mean age 66.7 ± 11.7 years, BMI 25.7 ± 4.4. LS BMD and TBS were weakly correlated (r2 = 0.16). The correlation (Vex excluded) between age and BMD was +0.03, between age and TBS -0.34. According to age group, LS BMD was 1.2 to 3.2% higher before excluding Vex (p < 0.001). TBS had an insignificant change of <1% after excluding Vex. LS BMD (Vex) decreased by 4.6% between 52.5 and 62.5 years, and increased by 2.6% between 62.5 and 77.5 years. TBS (Vex excluded) values decreased steadily with age with an overall loss of 8.99% between 52.5 and 77.5 years. Spine TBS, femoral neck, and total hip BMD gradually decreased with age, reaching one SD between the oldest and youngest group. CONCLUSIONS TBS is not affected by DD. While BMD increases after 62.5 years, TBS continues to decline. For lumbar spine evaluation, in view of its independence from DD, TBS should play a leading role in the diagnosis in complement to BMD.

Abstract
Wnt reception at the membrane is complex and not fully understood. CD44 is a major Wnt target gene in the intestine and is essential for Wnt-induced tumor progression in colorectal cancer. Here we show that CD44 acts as a positive regulator of the Wnt receptor complex. Downregulation of CD44 expression decreases, whereas CD44 overexpression increases Wnt activity in a concentration-dependent manner. Epistasis experiments place CD44 function at the level of the Wnt receptor LRP6. Mechanistically, CD44 physically associates with LRP6 upon Wnt treatment and modulates LRP6 membrane localization. Moreover, CD44 regulates Wnt signaling in the developing brain of Xenopus laevis embryos as shown by a decreased expression of Wnt targets tcf-4 and en-2 in CD44 morphants.

Abstract
OBJECTIVE To evaluate the longitudinal relationship between moderate chronic kidney disease (CKD), decline in kidney function, and microalbuminuria with subsequent cognitive decline and incident dementia. METHODS This study is based on a population-based cohort of 7,839 subjects over 65 years with 7 years of follow-up. Glomerular filtration rate was estimated (eGFR) using the CKD-EPI equation. Global cognitive function was assessed using the Mini-Mental State Examination (MMSE) and dementia was actively screened and diagnosed. RESULTS At baseline, 12% of the participants had an eGFR <60 mL/min/1.73 m(2). A total of 564 incident dementia cases were diagnosed during the follow-up. Low baseline eGFR values were not associated with an increased risk of incident dementia or cognitive decline over the 7-year follow-up, except a borderline significant association with dementia with vascular component. However, eGFR decline over the first 4-year period was associated with higher risk of dementia with vascular component (relative risk = 5.35 [1.76-16.3] in those with eGFR decline >4 mL/min/1.73 m(2)/y compared with those <4) and with higher cognitive decline on the MMSE (-0.12 points, p < 0.01 in those with eGFR >4 mL/min/1.73 m(2)/y compared with those <4) in the 3 subsequent years. Proteinuria tended to be associated with an increased risk of subsequent dementia with vascular component. CONCLUSIONS Despite a large sample and a long follow-up, we found no increased risk of cognitive decline or dementia associated with low eGFR level. However, faster eGFR decline was associated with global cognitive decline and incident dementia with vascular component, suggesting that this association may be mediated by vascular mechanisms.

Abstract
OsteoLaus is a cohort of 1400 women 50 to 80 years living in Lausanne, Switzerland. Clinical risk factors for osteoporosis, bone ultrasound of the heel, lumbar spine and hip bone mineral density (BMD), assessment of vertebral fracture by DXA, and microarchitecture evaluation by TBS (Trabecular Bone Score) will be recorded. TBS is a new parameter obtained after a re-analysis of a DXA exam. TBS is correlated with parameters of microarchitecture. His reproducibility is good. TBS give an added diagnostic value to BMD, and predict osteoporotic fracture (partially) independently to BMD. The position of TBS in clinical routine in complement to BMD and clinical risk factors will be evaluated in the OsteoLaus cohort.

Abstract
UNLABELLED Ultra-orthodox Jewish lifestyle, which encourages modest dress and indoor scholarly activity, represents a risk factor for vitamin-D deficiency. Our study in healthy young males from higher education religious institutions located in the same geographical area showed frequent and severe vitamin D deficiency, strongly correlated with the degree of sun exposure. However, PTH level was usually normal. INTRODUCTION Ultra-orthodox Jewish lifestyle encourages modest dress and indoor scholarly activity. As such, it represents a risk factor for vitamin-D deficiency, a worldwide problem previously underestimated in sunny countries. Our aim was to characterize the vitamin-D status of religious Jewish males according to sun exposure and outdoor activity, and study the correlation between serum 25-hydroxyvitamin D (25(OH) D) and PTH level. METHODS Seventy-four young adult males were recruited from three Jewish higher education institutions (Yeshiva) in Jerusalem. Yeshiva-A ultra-Orthodox students (aged 20.1 ± 0.6) wear traditional clothing, live in dormitories and stay mostly indoor. Yeshiva-B ultra-Orthodox students (aged 33.0 ± 4.2) dress similarly but have regular outdoor activities. Yeshiva-C religious students (aged 19 ± 2.0) participate in a mixed army/Yeshiva program. Weekly outdoor activity time and degree of sun exposure were estimated by questionnaire. RESULTS 25(OH)D was 8.9 ± 3.6, 10.2 ± 5.7 and 21.7 ± 10.4 ng/ml (mean ± SD) in Yeshiva A, B and C. 25(OH)D was correlated with degree of sun exposure (r = 0.54, p < 0.0001) and inversely correlated with PTH (r = -0.3, p = 0.01). Levels below 20 ng/ml were considered as vitamin D deficiency. PTH was normal in 87% of vitamin D-deficient subjects from Yeshiva-A and Yeshiva-C (mean age 20), compared to 52% of Yeshiva-B students (mean age 33). Bone mineral density studied in a random subset (n = 14) of vitamin D-deficient subjects showed Z-scores of -1.5 ± 1.0, -1.8 ± 0.8, -2.1 ± 0.4 in femoral neck, spine and radius. CONCLUSIONS Severe vitamin-D deficiency is extremely prevalent in ultra-Orthodox males. Despite rare secondary hyperparathyroidism, they represent an important previously unrecognized high-risk group for metabolic bone disease.

Abstract
BACKGROUND Neural stem and progenitor cells of the Enteric Nervous System (ENS) are regarded as a novel cell source for applications in regenerative medicine. However, improvements to the current ENS cell culture protocols will be necessary to generate clinically useful cell numbers under defined culture conditions. Beneficial effects of physiologically low oxygen concentrations and/or the addition of anti-oxidants on propagation of various types of stem cells have previously been demonstrated. In this study, we tested the effects of such culture conditions on ENS stem and progenitor cell behavior. METHODS Enteric neural progenitor cells were isolated from postnatal day 3 mouse intestine and propagated either as monolayers or neurosphere-like bodies. The influence of hypoxic culture conditions and/or anti-oxidants on enteric cell propagation were studied systematically using proliferation, differentiation and apoptosis assays, whereas effects on gene expression were determined by qRT-PCR, western blot, and immunocytochemistry. KEY RESULTS Both hypoxic culture conditions and anti-oxidants supported a significantly improved enteric cell propagation and the generation of differentiated neural cell types. Enteric neural progenitors were shown to be specifically vulnerable to persistent oxidative stress. CONCLUSIONS & INFERENCES Our findings are consistent with previous reports of improved maintenance of brain stem cells cultured under reduced oxygen stress conditions and may therefore be applied to future cell culture protocols in ENS stem cell research.
