Clinical trials

Adolescents and young adults receiving child welfare services constitute a vulnerable population, with an overrepresentation of mental health issues and past trauma, often exacerbated by a difficult transition to independence. Current support focuses mainly on material needs, lacking specific interventions targeting psychological resilience. This study draws on literature demonstrating that the development of emotional skills and post-traumatic growth are major protective factors promoting psychosocial adaptation and mental health.

The diagnosis of cancer can be a major trigger for new sleep problems, especially insomnia, in people who did not have sleep issues before. Insomnia may appear early in the care pathway and can continue over time, often interacting with other physical or emotional symptoms. The main goal of this preliminary study is to describe how insomnia develops during the first months after a cancer diagnosis in patients who had no sleep problems at the time of diagnosis. This will be done through regular follow-up over time. A secondary aim is to identify the factors that may contribute to the onset or persistence of insomnia, such as the cancer treatments patients receive, as well as any medical or non-medical therapies used to manage sleep difficulties. The study will also look at whether patients who develop sleep problems are referred to psychologists trained in specific therapies for insomnia, and how well they follow and adhere to these treatments.

The prevention and management of pediatric obesity require a thorough understanding and consideration of the various components of energy balance (i.e., intake and expenditure) and their interactions. Total energy expenditure (TEE) consists of resting metabolism (RM), energy expenditure induced by physical activity (EEPA), and dietary thermogenesis (DTE). While RM and EEPA are the two main contributors to TEE, DTE is often overlooked, even though it can account for around 10% of our daily energy expenditure. In fact, few studies have prioritized the evaluation of the thermic effect of food (TEF), defined as the increase in energy expenditure above the basal metabolic rate when fasting, despite the fact that it accounts for about 10% of total daily energy expenditure. It has been suggested that TEF may play a role in the development or maintenance of obesity. Some studies indicate a reduction in TEF in individuals living with obesity, possibly due to lower postprandial activation of the sympathetic nervous system, thereby limiting the thermogenic response after meals. Conversely, several studies have reported no decrease in TEF in individuals living with obesity. Due to these conflicting results, no consensus has been reached on the response of TEF in individuals with obesity compared to those of normal weight. While our team recently conducted a systematic review of the literature in this area, identifying a glaring lack of evidence, the few results available suggest a potential reduction in TEF in children and adolescents with obesity, contributing to minimizing the optimization of their daily energy balance. In their study, Maffeis and colleagues show, for example, a significantly reduced TEF in adolescents with obesity compared to their normal-weight counterparts, despite a higher-calorie test meal adapted to their energy needs. These results are consistent with those proposed by Salas-Salvado the following year, which suggest a reduced TEF in obese adolescents, associated with their percentage of body fat.This research suggests the need to consider the effects of weight status, body composition, and the caloric composition of a meal in order to better understand TEF in this population. Furthermore, while our team has repeatedly highlighted adaptations in resting metabolism and exercise metabolism in response to weight loss in obese adolescents, the TEF responses to these interventions have also been little studied in adolescents. To our knowledge, there is only one study that has qualitatively assessed this adaptation of TEF to weight loss in this population. According to the authors, while DHEA was reduced at baseline in obese adolescents compared to their normal-weight counterparts, weight loss appeared to increase DHEA levels, but this remains to be confirmed. In this context, the objective of this study is to evaluate the effects of weight loss on dietary thermogenesis in obese adolescents. It will also compare the thermogenesis of these adolescents before weight loss with that of adolescents of normal weight.

Background: Endometriosis is a chronic gynecological condition characterized by the ectopic presence of endometrial tissue outside the uterine cavity. It affects approximately 2 to 10% of women of reproductive age and up to 50% of women with chronic pelvic pain. In France, between 1.5 and 2.5 million women are estimated to be affected. Endometriosis significantly impairs quality of life, with consequences on cognitive, behavioral, sexual, and emotional well-being, and has substantial socio-economic impact. Rationale: Current medical and surgical treatments primarily aim to reduce pain and preserve fertility but show limited effectiveness and are often discontinued due to adverse effects. Many women resort to self-management strategies, which may pose risks if not properly supervised. A multidisciplinary and integrative approach is essential to address the complex and multifactorial symptoms of endometriosis. Therapeutic patient education (TPE) is a recommended strategy that can empower patients in the management of chronic conditions, yet remains underdeveloped in endometriosis care pathways. Objective: This study aims to evaluate the effectiveness of a multidisciplinary educational program combined with nurse-led telephone follow-up on the quality of life of patients with endometriosis. Methods: The intervention will consist of a series of workshops led by various healthcare professionals (medical and paramedical), alongside regular nurse-led telephone follow-up. This approach intends to provide continuous support, assess patients' evolving needs, and facilitate access to supportive care services, particularly within regional endometriosis networks (ENDAURA and ENDOSUD). Expected Outcomes: The study will assess whether this intervention improves quality of life among women with endometriosis. It also aims to provide evidence for the scalability and transferability of such a program at a national level, in alignment with current public health priorities.

People with a low BMI (\<17.5) are most often considered to have anorexia nervosa (AN). However, recent literature suggests that there is a category of individuals with the same low BMI who do not meet the diagnostic criteria for anorexia nervosa but who have specific differences that make them a separate entity: constitutional thinness (CM). Constitutional thinness differs from anorexia nervosa in several ways. First, unlike AN, CM individuals do not have eating disorders and express a strong desire to gain weight. Another difference concerns the menstrual cycle: without oral contraception, AN individuals experience amenorrhea, while CM individuals have regular menstrual cycles. Biological signs of malnutrition are also present in anorexia nervosa, whereas this is not the case in constitutional thinness. Indeed, concentrations of IGF1, free T3, and leptin are significantly reduced in AN compared to healthy subjects, whereas there is no significant difference between healthy subjects and CT. Finally, in terms of body composition, there is a significant difference in particular in the percentage of fat mass between MC and AM subjects, with the MC group having a significantly lower percentage of fat mass than the control subjects but significantly higher than the AM subjects. The clinical management of MC patients could involve nutritional management of patients but also management in the form of an Adapted Physical Activity intervention program. However, this type of program using physical activity and a nutritional approach must be based on a characterization of the energy profile and physical abilities of MC patients, which remains to be studied. Germain et al. proposed measuring the physical activity level of MC patients using Actiheart (a combination of heart rate and accelerometer) and compared it with that of normal-weight (NW) individuals, finding no difference between the groups. However, this analysis remains a secondary analysis of their study, as the statistical power and choice of tool are certainly not appropriate for this question. Our team recently conducted the Nutrilean project, which for the first time questioned the aerobic and muscular capacities of women with CM compared to their NP counterparts. While our results show lower force production capacity in CM patients, suggesting neuromuscular adaptations to the chronic mechanical unloading caused by CM rather than an impairment of contractile abilities themselves, this remains to be explored more specifically. Indeed, these differences disappeared after normalization to body weight or muscle mass, suggesting a reduced gross force production capacity, but probably reflecting a normal physiological adaptation to low body and muscle mass. It now appears necessary to carry out more specific neuromuscular analyses in order to better understand the mechanisms, adaptations, and/or potential neuromuscular dysfunctions in this population. Similarly, while the results do not appear to show any impairment in the aerobic capacity of CM, they do highlight a potential impairment in their energy efficiency during locomotion, which may also reflect an adaptation to chronic exposure to lower mechanical loads. In this context and following on from the work carried out to date by our team, the main objective of this study is i) to compare the lipid oxidation capacity and energy cost of walking between MC and NP participants; ii) to explore the adaptations of this energy cost in MC women in response to mechanical overload.

Current literature suggests that part of the energy response to weight loss is not due to changes in fat mass and lean mass, but rather to a homeostatic adaptation aimed at limiting or even preventing weight loss and preserving individuals' energy reserves, an adaptation known as "adaptive thermogenesis". This phenomenon calls for a closer look at the respective contributions of metabolic and mechanical changes induced by weight variations, with greater consideration given to the recently proposed hypothesis of dual regulation of homeostatic energy balance involving both leptin-dependent and "gravitostatic" pathways . While leptin-dependent regulation of body weight has been described and reinforced several times since the 1950s, the gravitostatic conception of this regulation is more recent and hypothesizes that terrestrial animals use gravity to regulate their body weight through receptors and pathways that have not yet been identified. This regulation would involve adaptations in energy consumption based on body weight when working against gravity, involving weight detection by osteocytes in weight-bearing bones, and leading to feedback regulation of energy metabolism and body weight . Preclinical and clinical studies conducted on rodents and human participants have shown a reduction in body weight after several weeks of mechanical overload (simulating weight gain), explained by adaptations in their food intake and energy metabolism , adaptations suggested to be particularly due to the regulation of muscle mass. Interestingly, preliminary results from this group highlight specific post-weight loss energy adaptations to such simulated weight regain in adolescents with obesity, suggesting the establishment of specific mechanisms promoting weight regain. Indeed, after weight loss, energy metabolism during locomotion was explored with and without simulated weight regain, and interestingly, energy expenditure did not return to pre-weight loss values, as a potential means of preserving weight regain. More recently, the investigators team has been able to show that such mechanical simulation of weight gain in adolescents with obesity but stable weight does not lead to an increase in their energy expenditure during locomotion, further reinforcing a susceptibility to not activating energy defense mechanisms against this weight gain.Overall, these results suggest the presence of mechanisms for preserving body mass by conserving energy stores as a compensatory defense system against weight loss, while highlighting the absence of activation of these mechanisms in the context of simulated weight gain. Indeed, while the compensatory mechanisms implicated in response to weight fluctuations have thus far been nutritional in nature, these energy adaptations, if confirmed, would suggest an upstream activation mechanism, particularly as a tonic signal for homeostatic control. It seems necessary to study in greater depth the energy adaptations to weight variations in young people with obesity, both metabolic and mechanical, in order to better understand the control of their energy balance and the mechanisms involved, which corresponds to the objectives of this project. The objective of this project is therefore to study energy adaptations (energy cost and use of energy substrates) to simulated weight loss during incremental walking exercise. Adolescents with obesity will perform a walking exercise on an AlterG (anti-gravity) treadmill, first without and then with a simulated weight loss that places them in the overweight or normal weight category.

It is estimated that the prevalence of dementia in France is 5% for people over 65 years of age and that this increases to 18% for people over 75 years of age. Behavioral disorders are frequent in patients with dementia and are the main cause of institutionalization, representing up to 50% of cases. Dementia syndromes can be translated into behavioral and psychological symptoms of dementia (BPSD), which are defined as perceptual, mood or behavioral disorders. To date, there is no cure for dementia, but certain measures can be taken to reduce symptoms. The HAS suggests that physical exercise would reduce BPSD and could improve the ability to perform activities of daily living or slow down the cognitive decline of this type of patient. Indeed, several articles have highlighted the benefits of physical activity in demented patients. A meta-analysis has shown a significant decrease in BPSD via the Neuropsychiatric Inventory (NPI) score. Nevertheless, it is often observed that there is a difficulty in adhering to the program in very elderly population groups. Dance is a complete physical activity that integrates physical, cognitive and social elements. A meta-analysis has shown that dance has a significant effect on global cognition but also on neuroplasticity and physical functioning in patients with mental disorders. The music component of dance also has an effect on the behavioral problems of demented patients, stimulating language ability and social and emotional function. However, at present, no study of good methodological quality has been able to demonstrate the effectiveness of dance-based physical activity for the treatment of dementia symptoms. As a result of these findings, the APAISE project was developed and should help slow the onset of BPSD in patients with dementia.

Every year in France, 2 million falls by people over 65 are responsible for 10,000 deaths, the leading cause of accidental death, and more than 130,000 hospitalizations. The main objective of this study is to evaluate the evolution of mobility in older people living in nursing homes, following 12 foot health workshops, carried out by a health professional, including the wearing of minimalist shoes.

End-stage renal disease (ESRD) is a condition in which the filtration function of the kidneys has deteriorated, necessitating dialysis or transplantation. With an aging population, the number of patients undergoing dialysis for CKD is constantly increasing. There are different types of dialysis treatment: hemodialysis and peritoneal dialysis. Hemodialysis involves exchanges between blood and a dialysate (a liquid used to purify blood) via a dialyzer (artificial filter), coordinated by a generator. This method requires a vascular approach, of which there are 3 types: the arteriovenous fistula (AVF), the arteriovenous graft and the central venous catheter. The AVF remains the vascular access of choice for hemodialysis sessions, and its preservation is an essential objective for patients with CKD. One of the major challenges for AVFs is to achieve a successful puncture, an act performed around 310 times a year per patient, for dialysis performed three times a week with double needles. This repeated procedure can cause damage to the AVF, leading to complications such as stenosis, thrombosis, aneurysm, superficial infection, hematoma, bleeding, parietal rupture or dissection. However, there is no official recommendation on the most conservative puncture technique for AVF. In view of the number of patients concerned and the recurrence of puncture, it would seem essential to evaluate the impact of bevel orientation on the occurrence of complications during dialysis by means of a randomized prospective study.
