Abstract
Tramadol and diclofenac are effective analgesics for pain relief of any complication, however, there are few studies showing the superiority of one over the other. This study aimed to evaluate and compare the analgesic efficacy of diclofenac and tramadol for postoperative pain treatment of laparoscopic surgery of cholecystectomy. There were 120 patients recently operated by laparoscopic surgery of cholecystectomy, who were randomly distributed in two groups: tramadol and diclofenac, administered intramuscularly for a maximum period of five days and demographic and clinical data were collected, as well as the pain evolution during the study period using the verbal numerical scale (VNS) and the functional activity scale (FAS). The results showed a predominance of the male population and an excess of patients with obesity in the tramadol group, and there were no significant differences between the analgesics, but a faster acceptance was observed with tramadol. In conclusion, tramadol is slightly superior to diclofenac, but it cannot be affirmed because there were no significant differences, more studies combining both and comparing them with placebos are suggested.

Abstract
Introduction Certain neuropsychiatric symptoms (NPS), namely apathy, depression and anxiety demonstrated great value in predicting dementia progression representing eventually an opportunity window for timely diagnosis and treatment. However, sensitive and objective markers of these symptoms are still missing. Objectives To investigate the association between automatically extracted speech features and NPS in early-stage dementia patients. Methods Speech of 141 patients aged 65 or older with neurocognitive disorder was recorded while performing two short narrative speech tasks. Presence of NPS was assessed by the Neuropsychiatric Inventory. Paralinguistic markers relating to prosodic, formant, source, and temporal qualities of speech were automatically extracted, correlated with NPS. Machine learning experiments were carried out to validate the diagnostic power of extracted markers. Results Different speech variables seem to be associated with specific neuropsychiatric symptoms of dementia; apathy correlates with temporal aspects, anxiety with voice quality and this was mostly consistent between male and female after correction for cognitive impairment. Machine learning regressors are able to extract information from speech features and perform above baseline in predicting anxiety, apathy and depression scores. Conclusions Different NPS seem to be characterized by distinct speech features which in turn were easily extractable automatically from short vocal tasks. These findings support the use of speech analysis for detecting subtypes of NPS. This could have great implications for future clinical trials. Disclosure No significant relationships.

Abstract
Background The primary progressive aphasia (PPA) diagnosis trajectory is debated, as several changes in diagnosis occur during PPA course, due to phenotype evolution from isolated language alterations to global cognitive impairment. The goal of the present study, based on a French cohort, was to describe the demographics and the evolution of subjects with (PPA) in comparison with Alzheimer’s disease (AD) on a period of 7 years. Methods We conducted a repeated cross-sectional study. The study population comprised individuals with PPA and AD diagnosis (N=167,191) from 2010 to 2016 in the French National data Bank (BNA). Demographic variables, MMSE scores, diagnosis status at each visit and prescribed treatments were considered. Results From 2010 to 2016, 5186 patients were initially diagnosed with PPA, 162,005 with AD. Compared to AD subjects, significant differences were found concerning age (younger at first diagnosis for PPA), gender (more balanced in PPA), education level (higher in PPA) and MMSE score (higher of 1 point in PPA). Percentage of pending diagnosis, delay between first consultation and first diagnosis and the number of different diagnoses before the diagnosis of interest were significantly higher in PPA group compared to AD group. Pharmacological and non-pharmacological treatments were significatively more recommended following PPA than AD diagnosis. Conclusion This study improves the knowledge of PPA epidemiology and has the potential to help adopting appropriate public health service policies. It supports the hypothesis that PPA is diagnosed later than AD. The PPA diagnosis increases the prescription of non-pharmacological treatments, especially speech and language therapy (SLT) that is the main treatment available and most effective when at the initial stage.

Abstract
A Watt-level continuous and single frequency blue laser at 461 nm is obtained by frequency-doubling an amplified diode laser operating at 922 nm via a LBO crystal in a resonant Fabry-Pérot cavity. We achieved a best optical conversion efficiency equal to 87% with more than 1 W output power in the blue, and limited by the available input power. The frequency-converted beam is characterized in terms of long term power stability, residual intensity noise, and geometrical shape. The blue beam has a linewidth of the order of 1 MHz, and we used it to magneto-optically trap 88Sr atoms on the 5s2 1S0 - 5s5p 1P1 transition. The low-finesse, linear-cavity doubling system is very robust, maintains the lock for several days, and is compatible with a tenfold increase of the power levels which could be obtained with fully-fibered amplifiers and large mode area fibers.

Abstract
Cervical cancer is the fourth most common cancer in women. In 2018, it was estimated that 570000 women were diagnosed with cervical cancer worldwide, and about 311000 women died from the disease. An efficient technique is essential for solving the complication in the diagnosis of cervical cancer images. In this research, a new method is developed for cervical cancer image segmentation. First, the RGB image is converted into an HSI color model. Then, the thresholding is applied to the saturation and intensity components to get binary images. These binary images are combined to get a new mask. Using the connected component concept, nucleus and cytoplasm are segmented accurately. For the performance evaluation, peak signal-to-noise ratio (PSNR), mean square error (MSE), structural similarity index (SSIM), image quality index (IQI), structural content (SC), normalized cross-correlation (NK), precision (PR), recall (RC), the average difference (AD), and image fidelity (IF) are taken. The proposed techniques' highest PSNR values are 44.2341, 46.7953, 60.5925, and 61.4862, respectively. The proposed segmentation technique can attain a high PSNR (>40db) value at a threshold value equal to 0.1. Also proposed approach attains good precision, recall, and SSIM values. The lowest MSE values using proposed segmentation techniques are 0.0454, 0.0351, 0.0924, and 0.0271 individually. The AD, NK, SC, NAE, and LMSE values for the implemented approach are low, showing that the segmented image's quality is very good. Thus, the proposed model performed better compared to other methods.

Abstract
The combined provision of an arising number of dementia cases, and the substantial absence of effective treatments, led the scientific community toward the identification of early phases of this condition. Such an effort aims at the recognition of therapeutic windows and the characterization of the disease's different grades. In the last years, Motor and Cognitive Dual-Tasks (MCDT) have been widely used to address the early diagnosis of several neurocognitive disorders, among which dementia. Here we present different protocols: the walking MCDT, the toe-tapping MCDT, and the forefinger-tapping MCDT. Moreover, each task has been performed under different cognitive conditions: no cognitive effort, counting backwards by 1, 3, and 7. In this work, we report the results obtained through the combination of different motor and cognitive tasks, and we present 2 brand-new MCDT protocols, attempting to identify a sweet-spot for early diagnosis of dementia.

Abstract
Hydrocolloids are used as stabilizing agents in order to enhance the physical stability of emulsions during their storage. However, they can also play an important role in nutrient release and bioavailability. In this context, the aim of this research was to study the effect of the emulsion type and thickener type on the physical-structural changes and free fatty acid release during in vitro digestion. Oil-in-water emulsions were prepared with different particle sizes (CE: conventional emulsions and NE: nanoemulsions) and thickening agents (starch and xanthan gum). The experimental conditions of homogenization used allowed food emulsions to be obtained at the microscale and nanoscale, with particle sizes ranging among 3.2-3.4 μm and 78-107 nm for CE and NE, respectively. The addition of thickening agents (XG and ST) modified the physical properties of emulsions (particle size, zeta potential and stability) slightly, and thickened samples with similar viscosity were obtained. The kinetics of FFAs released during the in vitro intestinal digestion showed no significant differences (p > 0.05) in the digestion rate among samples; however, emulsion and thickener types decreased the final extent of free fatty acids, being more evident for those samples with starch. Xanthan gum kept the particle size of nanoemulsions stable during the oral and gastric phases, which promoted the release of FFAs during the intestinal phase. Therefore, xanthan gum could be used as a thickening agent of nanoemulsions exerting a minor impact on their lipid bioaccessibility.

Abstract
La prise en charge non-pharmacologique de la maladie d’Alzheimer et des maladies apparentées (MA) représente un enjeu de santé majeur chez les personnes âgées . L’environnement Enrichi (EE), combinaison de stimulations cognitive, physique et d’engagement social en contexte émotionnel positif, apparaît comme une méthode efficace pour lutter contre la progression d’une MA . La principale difficulté est de proposer aux patients un EE adapté et motivant. Les serious games peuvent aider dans ce sens . Xtorp est un Serious exerGame (à activité physique, SeG) d’action/aventure développé pour KinectTM. Le joueur pilote un sous-marin (Fig. 1). Il doit devenir Amiral 5 étoiles en collectant de l’expérience au cours de batailles et missions. Dix patients (MA stade léger) et 8 témoins ont suivi un programme d’entrainement avec le jeu durant 1 mois, réparties en 12 séances. Les performances au jeu, les émotions perçues (PANAS) et l’intensité d’effort physique induite par le jeu ont été étudiées. Tous les participants ont terminé au moins une fois Xtorp. Les patients ont une capacité de jeu inférieure aux témoins (temps total de jeu et vitesse de progression patents : 420 minutes et 185 points d’expérience/minute, témoins : 489 minutes et 287 points d’expérience/minute). Les patients et les témoins n’ont quasiment ressenti que des émotions positives, légèrement plus fortes pour les témoins (PANAS positifs patients : 27/50, témoins, 36/50 ; PANAS négatifs patients : 12/50, témoins 11/50). Enfin, le jeu a été stimulant physiquement mais à un moindre degré chez les patients (fréquence cardiaque de réserve moyenne et pic par séance patients : 33 % et 53 %, témoins : 44 % et 62 %). En conclusion Xtorp est un EE utilisable, motivant qui permet de réaliser une activité physique potentiellement modérée chez des patients présentant des troubles cognitifs.

Abstract
AbstractPurpose:Adjustment disorder with anxiety (AjD-A) is a common cause of severe anxiety symptoms, but little is known about its prevalence in old age.Methods:This cross-sectional study examined the prevalence of AjD-A in outpatients over the age of 60 who consecutively consulted 34 general practitioners and 22 psychiatrists during a 2-week period. The diagnosis of AjD-A was obtained using the optional module for diagnostic of adjustment disorder of the Mini International Neuropsychiatric Interview (MINI). The study procedure also explored comorbid psychiatric conditions and documented recent past stressful life events, as well as social disability and current pharmacological and non-pharmacological management.Results:Overall, 3651 consecutive subjects were screened (2937 in primary care and 714 in mental health care). The prevalence rate of AjD-A was 3.7% (n = 136). Up to 39% (n = 53) of AjD-A subjects had a comorbid psychiatric condition, mostly of the anxious type. The most frequently stressful life event reported to be associated with the onset of AjD-A was personal illness or health problem (29%). More than 50% of the AjD-A patients were markedly to extremely disabled by their symptoms. Compared to patients who consulted psychiatrists, patients who were seen by primary care physicians were older, had obtained lower scores at the Hamilton Anxiety Rating Scale, benefited less frequently from non-pharmacological management and received benzodiazepines more frequently.Conclusions:AjD-A appears to be a significantly disabling cause of anxiety symptoms in community dwelling elderly persons, in particular those presenting personal health related problems. Improvement of early diagnosis and non-pharmacological management of AjD-A would contribute to limit risks of benzodiazepine overuse, particularly in primary care settings.

Abstract
Background
Bridging of vitamin K antagonist (VKA) with heparin is usually not promoted during interventional or surgical procedures related to increased risk of bleeding and thrombotic events but this strategy has not been evaluated during TAVI.
Purpose
The aim of this study was to evaluate the rate of major bleeding and vascular complications after TAVI performed in patients with uninterrupted VKA.
Methods
From January 2016 to October 2017, consecutive patients who underwent TAVI with uninterrupted VKA (INR between 1.5 and 3.5) were prospectively included in a monocentric registry. TAVI were performed according to current guidelines and a 50UI/kg bolus of heparin was injected at the beginning of the procedure for all patients. Vascular and bleeding complications were assessed using the Valve Academic Research Consortium 2 (VARC2) and the Bleeding Academic Research Consortium (BARC) definitions at 30 day follow-up.
Results
A total of 88 patients were included with a median age of 84 years [81.8–87], 42% being female, the median STS score was 5.1 [4.1–7.5], the median CHADS2-VASc was 5.5 [5–6] and 60.2% had a chronic kidney failure. Median INR at time of implantation was at 2.1 [1.8–2.6]. VKA were used for atrial fibrillation (89.8%), mechanic mitral prosthesis (5.7%) or venous thromboembolic disease (4.5%). Trans femoral access was used in 88.6% of the patients. Major bleeding (BARC ≥3b) occurred in 5 patients (5,7%) and major vascular complications occurred in 7 patients (8%). Peripheral arterial disease (RR = 10.95; 95% CI: 1.63 to 73.75; p=0.014) and carotid access (RR=8.56; 95% CI: 1.19 to 61.51; p=0.033) were significantly associated with major bleeding. INR >2.5 was significantly associated with vascular complications (RR=7.14; 95% CI: 1.29 to 39.63; p=0.025). In multivariate analysis, Body mass index (OR=1.26; 95% CI: 1.02 to 1.57; p=0.032) and INR >2.5 (OR=18.91; 95% CI: 1.62 to 221.26; p=0.010) were independent factor significantly associated with vascular complications or major bleeding. Mortality rate at 30 days follow-up was 2.3%, there was no myocardial infarction and stroke rate was 4.5%.
Figure 1. Study flowchart
Conclusion
TAVI with uninterrupted VKA treatment seems to be feasible and safe with low risk of bleeding and vascular complications in this first single centre experience. Particular caution is advocated in low BMI patients and to keep INR<2.5.

Abstract
Alzheimer's disease (AD), the most frequent cause of dementia, is escalating as a global epidemic, and so far, there is neither cure nor treatment to alter its progression. The most important feature of the disease is neuronal death and loss of cognitive functions, caused probably from several pathological processes in the brain. The main neuropathological features of AD are widely described as amyloid beta (Aβ) plaques and neurofibrillary tangles of the aggregated protein tau, which contribute to the disease. Nevertheless, AD brains suffer from a variety of alterations in function, such as energy metabolism, inflammation and synaptic activity. The latest decades have seen an explosion of genes and molecules that can be employed as targets aiming to improve brain physiology, which can result in preventive strategies for AD. Moreover, therapeutics using these targets can help AD brains to sustain function during the development of AD pathology. Here, we review broadly recent information for potential targets that can modify AD through diverse pharmacological and nonpharmacological approaches including gene therapy. We propose that AD could be tackled not only using combination therapies including Aβ and tau, but also considering insulin and cholesterol metabolism, vascular function, synaptic plasticity, epigenetics, neurovascular junction and blood-brain barrier targets that have been studied recently. We also make a case for the role of gut microbiota in AD. Our hope is to promote the continuing research of diverse targets affecting AD and promote diverse targeting as a near-future strategy.

Abstract
With the advent of the Heliophysics/Geospace System Observatory (H/GSO), a complement of multi-spacecraft missions and ground-based observatories to study the space environment, data retrieval, analysis, and visualization of space physics data can be daunting. The Space Physics Environment Data Analysis System (SPEDAS), a grass-roots software development platform (www.spedas.org), is now officially supported by NASA Heliophysics as part of its data environment infrastructure. It serves more than a dozen space missions and ground observatories and can integrate the full complement of past and upcoming space physics missions with minimal resources, following clear, simple, and well-proven guidelines. Free, modular and configurable to the needs of individual missions, it works in both command-line (ideal for experienced users) and Graphical User Interface (GUI) mode (reducing the learning curve for first-time users). Both options have "crib-sheets," user-command sequences in ASCII format that can facilitate record-and-repeat actions, especially for complex operations and plotting. Crib-sheets enhance scientific interactions, as users can move rapidly and accurately from exchanges of technical information on data processing to efficient discussions regarding data interpretation and science. SPEDAS can readily query and ingest all International Solar Terrestrial Physics (ISTP)-compatible products from the Space Physics Data Facility (SPDF), enabling access to a vast collection of historic and current mission data. The planned incorporation of Heliophysics Application Programmer's Interface (HAPI) standards will facilitate data ingestion from distributed datasets that adhere to these standards. Although SPEDAS is currently Interactive Data Language (IDL)-based (and interfaces to Java-based tools such as Autoplot), efforts are under-way to expand it further to work with python (first as an interface tool and potentially even receiving an under-the-hood replacement). We review the SPEDAS development history, goals, and current implementation. We explain its "modes of use" with examples geared for users and outline its technical implementation and requirements with software developers in mind. We also describe SPEDAS personnel and software management, interfaces with other organizations, resources and support structure available to the community, and future development plans.

Abstract
This study examined the effectiveness of three different learning methods: trial and error learning (TE), errorless learning (EL) and learning by modeling with spaced retrieval (MR) on the relearning process of IADL in mild-to-moderately severe Alzheimer's Dementia (AD) patients (n=52), using a 6-weeks randomized controlled trial design. The participants had to relearn three IADLs. Repeated-measure analyses during pre-intervention, post-intervention and 1-month delayed sessions were performed. All three learning methods were found to have similar efficiency. However, the intervention produced greater improvements in the actual performance of the IADL tasks than on their explicit knowledge. This study confirms that the relearning of IADL is possible with AD patients through individualized interventions, and that the improvements can be maintained even after the intervention.

Abstract
Time-to-event analysis is frequently used in medical research to investigate potential disease-modifying treatments in neurodegenerative diseases. Potential treatment effects are generally evaluated using the logrank test, which has optimal power and sensitivity when the treatment effect (hazard ratio) is constant over time. However, there is generally no prior information as to how the hazard ratio for the event of interest actually evolves. In these cases, the logrank test is not necessarily the most appropriate to use. When the hazard ratio is expected to decrease or increase over time, alternative statistical tests such as the Fleming-Harrington test, provide a better sensitivity. An example of this comes from a large, five-year randomised, placebo-controlled prevention trial (GuidAge) in 2854 community-based subjects making spontaneous memory complaints to their family physicians, which evaluated whether treatment with EGb761 can modify the risk of developing AD. The primary outcome measure was the time to conversion from memory complaint to Alzheimer's type dementia. Although there was no significant difference in the hazard function of conversion between the two treatment groups according to the preplanned logrank test, a significant treatment-by-time interaction for the incidence of AD was observed in a protocol-specified subgroup analysis, suggesting that the hazard ratio is not constant over time. For this reason, additional post hoc analyses were performed using the Fleming-Harrington test to evaluate whether there was a signal of a late effect of EGb761. Applying the Fleming-Harrington test, the hazard function for conversion to dementia in the placebo group was significantly different from that in the EGb761 treatment group (p = 0.0054), suggesting a late effect of EGb761. Since this was a post hoc analysis, no definitive conclusions can be drawn as to the effectiveness of the treatment. This post hoc analysis illustrates the interest of performing another randomised clinical trial of EGb761 explicitly testing the hypothesis of a late treatment effect, as well as of using of better adapted statistical approaches for long term preventive trials when it is expected that prevention cannot have an immediate effect but rather a delayed effect that increases over time.

Abstract
Avec le vieillissement de la population, la maladie d’Alzheimer et les pathologies associées représentent un défi majeur de santé publique. Parallèlement, les nouvelles technologies de l’information et de la communication prennent une part de plus en plus importante dans notre vie quotidienne et peuvent être un support tant pour l’évaluation que pour une aide directe des usagers. Les serious games sont des applications informatiques, dont l’intention est de combiner, avec cohérence, à la fois des aspects sérieux (Serious) comme l’enseignement, l’apprentissage, la communication, la rééducation, avec des ressorts ludiques issus du jeu vidéo (Game). Dans le cadre du projet AZ@GAME [2] lauréat AAP e-santé no 1 des Investissements d’Avenir, des jeux sont en cours de développement avec pour objectif de stimuler les capacités cognitives et physiques du patient. Un des problèmes rencontrés concerne l’engagement des sujets à comprendre puis à pratiquer ces jeux. En effet, engagement et motivation diminuent quand le patient rencontre des problèmes d’utilisation. Nous présentons ici un système d’assistance automatisé basé sur la technologie Kinect. Trois groupes de patients (Plaintes mnésique : n = 10 ; âge moyen, 76,6 ; MCI : n = 10 âge moyen, 77,9 ; et maladie d’Alzheimer : n = 10 ; âge moyen, 79,9) ont participés à une séance d’entraînement utilisant un jeu pour stimuler l’attention concentration. Le jeu était proposé avec ou sans l’aide du système. Les résultats indiquent que tous les groupes ont eu de meilleures performances (score et temps de jeu) avec l’aide du système. Ce résultat est tout particulièrement important dans le groupe de patients Alzheimer (score > de 31 % et temps de réalisation < de 10 % avec le système). Compte tenu de ces résultats la prochaine étape aura pour objectif de proposer un système encore plus motivant à une population plus importante de patients.

Abstract
Les objets technologiques, dont les nouvelles technologies de l’information et de la communication (nTIC), ainsi que les jeux vidéo dits « sérieux » (serious games) envahissent notre quotidien depuis quelques années. Leur utilisation dans les disciplines médicales est actuellement en développement croissant, notamment dans le domaine des neurosciences et du vieillissement. L’objectif de ce symposium est de présenter, en premier lieu, les recommandations scientifiques actuelles sur l’utilisation des nTIC et des serious games dans la prise en charge du sujet âgé et des atteintes neuropsychiatriques pouvant être associées. Ensuite, seront présentées les méthodes, utilisant les nTIC et les serious games, permettant d’améliorer l’évaluation et le dépistage des troubles cognitifs et des symptômes thymiques et comportementaux, ainsi que les stratégies non pharmacologiques, utilisant ces outils technologiques, permettant la stimulation des performances cognitives et la prise en charge des perturbations thymiques.

Abstract
The management of neuropsychiatric symptoms (NPS) such as agitation and aggression is a major priority in caring for people with Alzheimer's disease (AD). Agitation and aggression (A/A) are among the most disruptive symptoms, and given their impact, they are increasingly an important target for development of effective treatments. Considerable progress has been made in the last years with a growing number of randomized controlled trials (RCTs) of drugs for NPS. The limited benefits reported in some RCTs may be accounted for by the absence of a biological link of the tested molecule to NPS and also by key methodological issues. In recent RCTs of A/A, a great heterogeneity design was found. Designing trials for dementia populations with NPS presents many challenges, including identification of appropriate participants for such trials, engagement and compliance of patients and caregivers in the trials and the choice of optimal outcome measures to demonstrate treatment effectiveness. The EU/US -CTAD Task Force, an international collaboration of investigators from academia, industry, non-profit foundations, and regulatory agencies met in Philadelphia on November 19, 2014 to address some of these challenges. Despite potential heterogeneity in clinical manifestations and neurobiology, agitation and aggression seems to be accepted as an entity for drug development. The field appears to be reaching a consensus in using both agitation and aggression (or other NPS)-specific quantitative measures plus a global rating of change for agitation outcomes based on clinician judgment as the main outcomes.

Abstract
BACKGROUND AND PURPOSE Musculoskeletal system deterioration among the aging is a major reason for loss of autonomy and directly affects the quality of life of the elderly. Articular evaluation is part of physiotherapeutic assessment and helps in establishing a precise diagnosis and deciding appropriate therapy. Reference instruments are valid but not easy to use for some joints. The main goal of our study was to determine reliability and intertester reproducibility of the MP-BV, an inertial sensor (the MotionPod(®) [MP]) combined with specific software (BioVal [BV]), for elbow passive range-of-motion measurements in geriatrics. METHODS This open, monocentric, randomized study compared inertial sensor to inclinometer in patients hospitalized in an acute, post-acute, and long-term-care gerontology unit. RESULTS Seventy-seven patients (mean age 83.5±6.4 years, sex ratio 1.08 [male/female]) were analyzed. The MP-BV was reliable for each of the three measurements (flexion, pronation, and supination) for 24.3% (CI 95% 13.9-32.8) of the patients. Separately, the percentages of reliable measures were 59.7% (49.2-70.5) for flexion, 68.8% (58.4-79.5) for pronation, and 62.3% (51.2-73.1) for supination. The intraclass correlation coefficients were 0.15 (0.07-0.73), 0.46 (0.27-0.98), and 0.50 (0.31-40 0.98) for flexion, pronation, and supination, respectively. CONCLUSION This study shows the convenience of the MP-BV in terms of ease of use and of export of measured data. However, this instrument seems less reliable and valuable compared to the reference instruments used to measure elbow range of motion in gerontology.

Abstract
OBJECTIVE The Multidomain Alzheimer Preventive Trial (MAPT study) was designed to assess the efficacy of isolated supplementation with omega-3 fatty acid, an isolated multidomain intervention (consisting of nutritional counseling, physical exercise, cognitive stimulation) or a combination of the two interventions on the change of cognitive functions in frail subjects aged 70 years and older for a period of 3 years. Ancillary neuroimaging studies were additionally implemented to evaluate the impact of interventions on cerebral metabolism (FDG PET scans) and atrophy rate (MRIs), as well as brain amyloïd deposit (AV45 PET scans). DESIGN PATIENTS 1680 subjects (mean age: 75.3 years; female: 64.8 %), enrolled by 13 memory clinics, were randomized into one of the following four groups: omega-3 supplementation alone, multidomain intervention alone, omega-3 plus multidomain intervention, or placebo. Participants underwent cognitive, functional and biological assessments at M6, M12, M24 and M36 visits. The primary endpoint is a change of memory function at 3 years, as assessed by the Free and Cued Selective Reminding test. All participants will be followed for 2 additional years after the 3-years intervention (MAPT PLUS extension study). INTERVENTIONS 1/Omega-3 supplementation: two soft capsules daily as a single dose, containing a total of 400 mg docosahexaenoic acid (DHA), i.e., 800 mg docosahexaenoic acid per day, for 3 years. 2/ Multidomain intervention: collective training sessions conducted in small groups (6-8 participants) in twelve 120-minute sessions over the first 2 months (two sessions a week for the first month, and one session a week the second month) then a 60-minute session per month in the following three areas: nutrition, physical activity, and cognition until the end of the 3 years. In addition to the collective sessions, individualized preventive outpatient visits exploring possible risk factors for cognitive decline are performed at baseline, M12 and M24. BASELINE POPULATION For cognition, the mean MMSE at baseline was 28.1 (± 1.6). About 58% and 42% of participants had a CDR score equal to 0 and 0.5, respectively. Regarding mobility status, 200 (11.9%) had a 4-m gait speed lower or equal to 0.8 m/s. According to the Fried criteria, 673 (42.1%) participants were considered pre frail, and 51 (3.2%) frail. The red blood cell DHA content was 26.1 ± 8.1 µg/g. Five hundred and three participants underwent baseline MRI. AV45 PET scans were performed in 271 individuals and preliminary results showed that 38.0% had a cortical SUVR > 1.17, which gave an indication of significant brain amyloïd deposit. DISCUSSION: The MAPT trial is presently the first largest and longest multidomain preventive trial relevant to cognitive decline in older adults with subjective memory complaints. The multidomain intervention designed for the MAPT trial is likely to be easily implemented within the general population.

Abstract
Successful therapeutic trials require well-targeted populations to demonstrate the effectiveness of a drug candidate. Most trials in the field of Alzheimer's disease (AD) have been conducted in patients with mild to moderate dementia. However, the advent of amyloid PET imaging has demonstrated that a significant proportion of individuals enrolled in such studies do not have evidence of brain amyloidosis and may in fact not have Alzheimer's disease. Further, dementia represents an advanced stage of neurodegeneration, perhaps too late for significant benefits of disease-modifying interventions. The successful development of effective disease-slowing therapies requires a study population selected in accordance with the mechanism of the specific intervention. An international task force of investigators from academia, industry, non-profit foundations, and regulatory agencies met in San Diego, California, USA, on November 13, 2013, to address issues related to screening and identification of clinical trial participants, and the ramifications of decisions made in this regard for drug development in AD and other dementias.

Abstract
The frailty syndrome has recently attracted attention of the scientific community and public health organizations as precursor and contributor of age-related conditions (particularly disability) in older persons. In parallel, dementia and cognitive disorders also represent major healthcare and social priorities. Although physical frailty and cognitive impairment have shown to be related in epidemiological studies, their pathophysiological mechanisms have been usually studied separately. An International Consensus Group on "Cognitive Frailty" was organized by the International Academy on Nutrition and Aging (I.A.N.A) and the International Association of Gerontology and Geriatrics (I.A.G.G) on April 16th, 2013 in Toulouse (France). The present report describes the results of the Consensus Group and provides the first definition of a "Cognitive Frailty" condition in older adults. Specific aim of this approach was to facilitate the design of future personalized preventive interventions in older persons. Finally, the Group discussed the use of multidomain interventions focused on the physical, nutritional, cognitive and psychological domains for improving the well-being and quality of life in the elderly. The consensus panel proposed the identification of the so-called "cognitive frailty" as an heterogeneous clinical manifestation characterized by the simultaneous presence of both physical frailty and cognitive impairment. In particular, the key factors defining such a condition include: 1) presence of physical frailty and cognitive impairment (CDR=0.5); and 2) exclusion of concurrent AD dementia or other dementias. Under different circumstances, cognitive frailty may represent a precursor of neurodegenerative processes. A potential for reversibility may also characterize this entity. A psychological component of the condition is evident and concurs at increasing the vulnerability of the individual to stressors.

Abstract
In the present work, the concentrations of Aβ11-x and Aβ17-x peptides (x=40 or 42), which result from the combined cleavages of β-amyloid precursor protein (AβPP) by β'/α or α/γ-secretases, respectively, were assessed in cerebrospinal fluid (CSF) samples from patients with Alzheimer's disease (AD) or mild cognitive impairment (MCI). Specific multiplexed assays were set up using new anti-40 and anti-42 monoclonal antibodies (mAbs) for the capture of these N-truncated Aβ peptides and anti-11 or anti-17 mAbs for their detection. The specificity, sensitivity and reproducibility of such assays were assessed using synthetic peptides and human cell models. Aβ11-x and Aβ17-x were then measured in CSF samples from patients with AD (n=23), MCI (n=23) and controls with normal cognition (n=21). Aβ11-x levels were significantly lower in patients with MCI than in controls. Compared with the combined quantification of Aβ1-42, total Tau (T-Tau) and phosphorylated Tau (P-Tau; AlzBio3, Innogenetics), the association of Aβ11-40, Aβ17-40 and T-Tau improved the discrimination between MCI and controls. Furthermore, when patients with MCI were classified into two subgroups (MCI ≤1.5 or ≥2 based on their CDR-SB (Cognitive Dementia Rating-Sum of Boxes) score), the CSF Aβ17-40/Aβ11-40 ratio was significantly higher in patients with CDR-SB ≤1.5 than in controls, whereas neither Aβ1-42, T-Tau nor P-Tau allowed the detection of this subpopulation. These results need to be confirmed in a larger clinical prospective cohort.

Abstract
The clinical progression of Alzheimer disease (AD) was studied in European subjects under treatment with AChE inhibitors (AChE-I) in relation to geographical location over a 2-years period. One thousand three hundred and six subjects from 11 European countries were clustered into 3 regions (North, South, West) and investigated with biannual follow-up over 2 years. Primary outcomes were cognitive, functional and behavioral measures. Caregiver burden, hospital admission and admission to nursing home were also recorded. Participant cognitive function declined non-linearly over time (MMSE: -1.5 pts/first year, -2.5 pts/second year; ADAScog: + 3.5 pts/first year, + 4.8 pts/second year), while the progression of behavioral disturbances (NPI scale) was linear. Neither scale showed regional differences, and progression of the disease was similar across Europe despite different health care systems. Functional decline (ADL, IADL) tended to progress more rapidly in Southern Europe (p=0.09), while progression of caregiver burden (Zarit Burden Interview) was most rapid in Northern Europe (5.6 pts/y, p=0.04). Incidences of hospital admission (10.44, 95%CI: 8.13-12.75, p < 0.001) and admission to nursing home (2.97, 95%CI: 1.83-4.11, p < 0.001) were lowest in Southern Europe. In general cognitive and functional decline was slower than in former cohorts. European geographical location reflecting differences in culture and in health care system does not impact on the progression of AD but does influence the management of AD subjects and caregiver burden.

Abstract
The knowledge of brain tissues characteristics (such as extracellular space and tortuosity) represents valuable information for the design of optimal MR probes for specific biomarkers targeting. This work proposes a methodology based on dynamic acquisition of relaxation time maps to quantify in vivo MRI contrast agent concentration after intra-cerebral injection in rat brain. It was applied to estimate the hindered diffusion in brain tissues of five contrast agents with different hydrodynamic diameters (Dotarem(®) ≈ 1 nm, P846 ≈ 4 nm, P792 ≈ 7 nm, P904 ≈ 22 nm and Gd-based emulsion ≈ 170 nm). In vivo apparent diffusion coefficients were compared with those estimated in an obstacle-free medium to determine brain extracellular space and tortuosity. At a 2 h imaging timescale, all contrast agents except the Gd-based emulsion exhibited significant diffusion through brain tissues, with characteristic times compatible with MR molecular imaging (<70 min to diffuse between two capillaries). In conclusion, our experiments indicate that MRI contrast agents with sizes up to 22 nm can be used to perform molecular imaging on intra-cerebral biomarkers. Our quantification methodology allows a precise estimation of apparent diffusion coefficients, which is helpful to calibrate optimal timing between contrast agent injection and MRI observation for molecular imaging studies.

Abstract
We present a new model of self-consistent coupling between low frequency, ion-scale coherent structures with high frequency whistler waves in order to interpret Cluster data. The idea relies on the possibility of trapping whistler waves by inhomogeneous external fields where they can be spatially confined and propagate for times much longer than their characteristic electronic time scale. Here we take the example of a slow magnetosonic soliton acting as a wave guide in analogy with the ducting properties of an inhomogeneous plasma. The soliton is characterized by a magnetic dip and density hump that traps and advects high frequency waves over many ion times. The model represents a new possible way of explaining space measurements often detecting the presence of whistler waves in correspondence to magnetic depressions and density humps. This approach, here given by means of slow solitons, but more general than that, is alternative to the standard approach of considering whistler wave packets as associated with nonpropagating magnetic holes resulting from a mirror-type instability.

Abstract
5-methoxypsoralen (5-MOP) stimulates pineal melatonin secretion, and a decrease in dark phase melatonin levels has been described in major depression. As exogenous melatonin has shown synchronizer properties, authors hypothesized that giving 5-MOP would have antidepressant properties. Twenty-six inpatients meeting the criteria of major depressive disorders were enrolled in a four-week, double blind trial of 5-MOP versus amitriptyline. Clinical improvement was identical in both treatment groups but biological changes were different in each group: 5-MOP patients showed an early nocturnal surge of melatonin levels that was maintained at the fourth treatment week, while melatonin levels remained unchanged in patients treated with amitriptyline.

Abstract
1680 participants were randomized over the recruitment period in MAPT study. A total of 1290 participants were recruited in the 7 University Hospital centers, and 390 participants in the 6 memory clinics around Toulouse Gerontopole / Alzheimer Disease research clinical center. The first randomization was on May 30, 2008, and the targeted number of randomized participants was reached on February 24, 2011; 2595 subjects were finally screened, of which 1680 fulfilled the eligibility criteria which represents 64.8%. Approximately, one quarter of screened people refused to participate after the detailed presentation of the study and 4.3% were still interested in participating but missed for unknown reasons the baseline visit even after repeated contacts. Of the 1810 subjects who signed the consent for participating to the study at the baseline visit, 130 (7.1%) were excluded because one of the eligibility criteria was not satisfied. Interestingly, the higher percentage of randomizations compared to screened participants is the personal contact source; almost 85 % of screened participants entered in the study. In an equivalent way, Medias and conferences are efficient recruiting sources to enrol volunteers in the study. Unexpectedly, only about 60% of screened participants from the hospital and GP sources were randomized and 33.2% from health care services. Almost a quarter of the randomized participants come from the hospital outpatients clinics and approximately 20% from public conferences. A total of 1128 contacts yielded to 556 screened volunteers and 345 randomized participants in the coordinating center of Toulouse. Thus, 30 % of contacts were recruited.
