Clinical trials

Obstetric ultrasonography is now an essential tool for monitoring pregnancy. In France, three ultrasounds are recommended during a singleton pregnancy (at 12, 22, and 32 weeks of amenorrhea) to improve maternal and neonatal care. Among the parameters studied, fetal weight estimation allows for the assessment of fetal growth and the detection of certain conditions such as intrauterine growth restriction or macrosomia. Fetal weight estimation is based primarily on the Hadlock formula, which combines several biometric measurements (head circumference, abdominal circumference, and femur length). This estimate has a margin of error of 6 to 10% compared to birth weight, which is still accurate enough to guide important medical decisions, such as inducing labor or performing a cesarean section. However, an estimation error can have negative consequences for both mother and child. Fetal macrosomia is defined as a birth weight greater than or equal to 4000 g. It affects approximately 5 to 10% of pregnancies. Screening is mainly based on ultrasound, particularly in the second and third trimesters. Macrosomia is associated with an increased risk of complications for the mother (cesarean section, postpartum hemorrhage, or deep vein thrombosis) and the child (shoulder dystocia, fractures, brachial plexus palsy, or neonatal asphyxia). These risks are increased in cases of macrosomia in the context of maternal diabetes. Within the gynecology-obstetrics department, physicians use the protocole of macrosomia screening described in the DAME trial. If macrosomia is suspected an additional ultrasound is performed at around 36 weeks of amenorrhea. The Hadlock formula is used to estimate fetal weight. The ultrasound criteria for suspecting macrosomia are an estimated fetal weight above the 95th percentile (90th percentile in cases of maternal diabetes) according to WHO curves. In these cases, induction is offered between 38 and 39 weeks of amenorrhea, if the cervix is favorable. A cesarean section is offered to the patient if the estimated fetal weight is greater than 5000 g in the absence of diabetes and greater than 4500 g in cases of associated diabetes. Nevertheless, the probability of a child being born macrosomic after ultrasound suspicion is between 17% and 80% on average, and 53% in our center. Although beneficial in the context of macrosomia, the effects of induced labor or cesarean delivery are not insignificant for the mother and her baby. In this context, the value of this study is to demonstrate that performing an ultrasound as close to the birth as possible could allow for a more reliable estimation of fetal weight and better detection of macrosomia in order to avoid unnecessary procedures. The investigators hypothesize that fetal weight estimation is more accurate when performed within 24 hours prior to delivery. When the assessment is conducted earlier, it inherently assumes a constant fetal growth rate until birth, which may not reflect actual growth patterns. A more precise estimation of birth weight could improve clinical decision-making and optimize maternal and neonatal care, potentially reducing unnecessary interventions such as labor induction or cesarean delivery.

Abortion is a fundamental right for women in France, where the legal time limit was extended from 14 to 16 weeks' gestation. This extension allows women, whose psychosocial determinants are poorly known, and who face various obstacles (personal, administrative, medical, or other), to access abortion. However, it may also expose them to psychological troubles and difficulties in accessing healthcare. This study aims to identify the psychosocial determinants and disruptions in the primary care pathway associated with late abortions (≥14 weeks' gestation \[WG\]) in order to propose preventive actions, particularly regarding contraception, screening, and referral, directly applicable in general practice.

Adapted physical activity for patients with haematological malignancies generally has positive effects on quality of life, fatigue and physical condition. However, some studies show little or no effect. This may be explained by inefficient protocols, but also by low rates of patient acceptability regarding the proposed exercises. The multiplicity of APA protocols and the fluctuation of their results mean that validity, methodology and effects on patients need to be verified before they can be considered for implementation in healthcare services. A program must prove its feasibility, but patients must also adhere to it. Acceptability can be measured by adherence, which represents the number of validated sessions in relation to the number of planned sessions, and by attrition, which corresponds to the number of stops or drop-outs for any reason. The various APA programs offered in the context of intensive auto or allograft treatment are limited, notably by adherence, which can fall by as much as 24%, and attrition, which can be as high as 67%. Optimization of the proposed exercises and follow-up methods is therefore necessary in order to propose an APA program that will be feasible, effective and acceptable to a maximum number of patients. To meet these objectives for patients with multiple myeloma eligible for autologous stem cell transplantation, the protocol for this study took into consideration the various recommendations of previous publications and the guidelines from HAS (French National Authority for Health). The ultimate goal of this study is to validate, in terms of effectiveness and acceptability, the methodology and in particular the use of new specific tools for optimizing an APA program. It will subsequently be offered to all patients with multiple myeloma eligible for autologous stem cell transplantation, independently of their age or physical condition, while respecting their rhythm and physical condition.

Chronic Myeloid Leukemia (CML) affects 820 people per year in France (2018), half of them are older than 60 years old. Tyrosine Kinase Inhibitors (TKI) are new kind of targeted therapy whose efficiency allow for a high rate of complete molecular response, leading to a disruption of treatment under certain conditions. Optimizing CML treatment is a major concern, particularly for adverse events management, treatment compliance and therapeutic response. Multiple studies demonstrated that grade ≤ II adverse events are most likely to be under reported by patients and clinicians. Although these adverse events are mostly reported by clinical examination, needing minimal treatment. These toxicities could alter daily and domestic living activities, potentially impacting treatment compliance and therapeutic response. Therefore, early detection of these adverse events is a major challenge for the prognosis and care of CML. The Advanced Practice Nurse (APN), a new health care professional, acquired the skills needed to independently follow, manage and care the patients with medical approvals. At international level, many studies, in oncology and in others domains, have been done to demonstrate the added value of the APN, particularly in improving patient's quality of life, management, care of drug-induced adverse events and treatment compliance. In France, because of the recentness of the profession, only few studies were have been conducted. The goal of this study is to demonstrate the benefit of APN in clinical follow-up, quality of life, treatment compliance, and therapeutic response of CML patients. These effects could be managed thanks to early detection and management of ≤ grade II adverse events during consultation, in partnership with the patients, and in collaborative working.

In France, the number of new cancer cases each year is rising steadily, while the number of deaths, although falling, is still around 157,000, including 23,000 from lung cancer alone. According to the French National Cancer Institute, there are three main methods of treating cancer: chemotherapy, radiotherapy and surgery. In recent years, new therapies have been developed, notably with the advent of immunotherapy and targeted therapies. On the other hand, although non-medical interventions (NMIs) such as osteopathy are recognized as improving the quality of life of cancer patients, there has been little research into their contribution when combined with conventional therapies. Studies have shown a link between the vagus nerve and cancer. Through its actions, the vagus nerve regulates homeostasis and immunity at local and regional levels, reducing systemic inflammation but maintaining local inflammation, which has an anti-tumour effect. At the same time, vagus nerve stimulation increases heart rate variability, which, when increased, is associated with improved vital prognosis in cancer patients. This stimulation can be achieved using a number of common, non-invasive osteopathic techniques. To date, no study has shown an objective and definitive link between vagus nerve stimulation and improved vital prognosis. However, several studies show that vagus nerve activity may be related to prognosis in cancer patients through regulation of HRV and possibly inflammation. Osteopathic manipulation to stimulate the vagus nerve could therefore have an effect on HRV. Improved HRV could therefore indirectly improve the prognosis of cancer patients. The first step is to test this clinical hypothesis: does osteopathic manipulation stimulate the vagus nerve in cancer patients? This will be done by measuring heart rate variability using rMSSD, the metric most representative of vagal tone. This randomized single-center pilot study will investigate the short-term effect of vagus nerve stimulation using osteopathic techniques on heart rate variability in lung cancer patients. Our hypothesis is that stimulation of the vagus nerve by gentle, non-invasive osteopathic manipulation would increase vagal tone and therefore improve HRV and quality of life in the short term, but also reduce anxiety experienced at the time of chemotherapy.
