Psycho-social Determinant for Sport Practised During Cancer

Different individual factors have been identified as playing an important role in physical activity (PA) practice. For example, sex, age, education level, socio-professional category, ethnicity, overweight seemed to impact PA level in general population and among cancer patient. Beyond the disease's effect, as well as its treatment, the socio-ecological approach has identified five group of factors associated to PA practice: individual factors, interpersonal factors, environmental factors, political factors and global factors. The aim of this mixed methods study is to identify the variables of the socioecological model facilitating PA practice, as well as PA level and preferences at different time during cancer (at diagnose, during treatment, after treatment).

French Registry for Monitoring Pregnancies for Multiple Sclerosis

METHODOLOGY Prospective, observational, multicentric and national epidemiological study, within the scope of the OFSEP, including all groups of patients eligible to participate in the Observatoire Français de la Sclérose en Plaque (OFSEP) (definite MS, radiologically isolated syndromes, clinically isolated syndromes, neuromyelitis optica (NMO) and NMO spectrum disorders), with no age limit and an ongoing pregnancy. Women will be followed during pregnancy and in the year after and their children until 6 years of age. STATISTICAL ANALYSIS To be determined for each specific question. EXPECTED RESULTS Interactions between pregnancy and MS course have been well characterized before the therapeutic era. Neurologists and patients are lacking information to weigh benefits and risks of DMDs used immediately before or during pregnancy, including short and long-term risks to the mother and to the child, but also after delivery. This study should help provide better answers to those questions as well as to still controversial questions about locoregional analgesia and breastfeeding. By following these patients within the Observatoire Français de la Sclérose en Plaque (OFSEP) cohort, the investigator will also have access to a comprehensive description of MS before pregnancy but also in the long term.

Disease Modifying Therapies Withdrawal in Inactive Secondary Progressive Multiple Sclerosis Patients Older Than 50 Years (STOP-I-SEP)

Multiple sclerosis (MS) usually evolves over decades and can present several phenotypes. Approximately 85% of newly diagnosed Multiple Sclerosis (MS) patients present the Relapsing-Remitting MS (RRMS) phenotype. After a mean time of approximatively 20 years, a large majority of these patients evolve to the so-called "Secondary Progressive MS" (SPMS) phase. SPMS is characterized by an irreversible disability progression not related to relapses, although relapses could be superimposed. Nevertheless, the shift in-between RRMS and SPMS is not clear. Different subtypes of SPMS have been recently defined by F Lublin et al. This classification takes into account persistent focal inflammatory activity (active vs inactive SPMS) along with disease progression (progressing vs non-progressing SPMS). In clinical routine, it is important to identify these stages of MS as they differently respond to the disease modifying therapies (DMTs). Introducing DMTs during the RRMS phase had consistently demonstrated a significant impact on the annual relapse rate (ARR) and on the short-term disability progression. Conversely, during the SPMS phase, the impact of DMTs remained uncertain on disability progression, especially in older patients, with "inactive" disease. As a matter of fact, the DMTs are considered to be anti-inflammatory by nature, but the focal inflammation reduces with age and disease duration. In addition, the DMTs have side effects and cost approximately 10,000 euros per year and per patient. In this context, the usefulness of continuing DMTs in "inactive" SPMS patients older than 50 years is questionable. In a preliminary retrospective study conducted at our Institute which enrolled 100 SPMS patients, the ARR remained stable 3 years after treatment withdrawal (0.07, 95% CI [0.05, 0.11]), relative to the 3 years prior to treatment withdrawal (0.12, [0.09, 0.16]). EDSS scores were available for 94 patients The percentage of patients experiencing a significant increase of their EDSS score during the 3 years after treatment withdrawal also remained stable compared to the 3 years prior treatment withdrawal. These preliminary data support the safety of DMTs withdrawal in selected SPMS patients. However, further prospective studies are needed to provide evidence-based guidelines for daily practice. This randomized controlled clinical trial thus aims to compare SPMS patients older than 50 years without evidence of focal inflammatory activity for 3 years, stopping DMTs versus patients with the same criteria still receiving treatment. We hypothesize that stopping DMTs will not induce an increased risk of disability progression or relapse in SPMS patients but will improve their quality of life and have an impact on treatment-related costs. So far, the impact of DMTs withdrawal in a selected SPMS population has not been explored. Having evidence-based recommendations on the treatment management of these patients is essential, considering the consequences in terms of disability, relapses, side effects, quality of life and costs. DMTs in MS are now available since 20 years, with an increasing number of approved molecules. As a matter of fact, this question concerns a large number of patients: a retrospective analysis of patients included in the Rennes EDMUS database allowed to identify 71 SPMS patients older than 50 years and without evidence of focal inflammatory activity for 3 years actually undergoing a DMT. For evident conflict of interests, the pharmaceutical firms will not promote or fund clinical trials on treatment withdrawal. A randomized controlled study initiated by academia and financed by public funding should be performed to explore these questions. We will evaluate the impact of these changes from the patient and the health system's points of view. The results of this clinical trial will lead to a concrete change in clinical practice.

Atlas of Human Cognition by SEEG (MAPCOG-SEEG)

The pre-surgical assessment of a cortectomy in patient suffering from a refractory epilepsy includes several examinations aiming both, to specify the epileptogenic zone (EZ) which must be resected and to evaluate functional and cognitive risks of surgery. Nevertheless, in some patients, non-invasive evaluation does not give formal answer. In these subjects, it is then necessary to carry out a second step, consisting of an invasive exploration by implantation of intracerebral electrodes during a Stereoelectroencephalography (SEEG). Due to its temporal and spatial resolution, the SEEG allows, besides the precise determination of the EZ, to carry out a functional mapping of the cortical regions likely to be included in cortectomy. Conventionally, this mapping is carried out on the basis of the cortical electrical stimulations applied to the implanted electrodes. If this approach is very robust for exploring primary functions such as motor skills or language, it cannot be used to evaluate more complex cognitive tasks such as face recognition or attention. Essential cognitive tasks on a daily basis. This has led to the development in recent years, in Grenoble, of a complementary approach to cerebral stimulation: Dynamic Spectral Imaging (ISD). Numerous experimental paradigms have demonstrated that the realization of a cognitive task associates with the generation within the cortical regions involved in its treatment of a particular cortical activity. This activity is characterized by oscillations of the cortical rhythm in high frequencies (> 40 Hz), called gamma activities. The ISD thus consists in mapping this gamma activity during various cognitive tasks, thus making it possible to study more widely the complexity of the cognitive functions. MAPCOG_SEEG aims to collect the cerebral recording of the patients who have performed this cognitive exploration to be able to in fine propose an Atlas of human cognition which takes advantage of the very rich information in terms of spatial and temporal resolution of the SEEG. Furthermore, it will exactly allow more to understand the impact of the epilepsy and the surgery of the epilepsy on the cognition.
