NCT ID: NCT06155877 Completed - Clinical trials for Health Knowledge, Attitudes, Practice

Testing The Effectiveness Of Two Interventions To Reduce Vaccine Hesitancy Among Adolescents

Kidivax
Start date: November 15, 2022
Phase: N/A
Study type: Interventional

Vaccines currently prevent several million deaths every year and more lives could be saved if vaccination take up increased. The World Health Organization identifies vaccine hesitancy as one of the ten most important threats to global health and emphasizes the importance of devising interventions to reduce vaccine hesitancy. The two most promising interventions rely on consensus messaging, which has robust but small effects, and interactive discussion, which has larger effects, but is difficult to scale up. School-based interventions aimed at adolescents have the potential to make the best of both types of interventions. Interventions that take place in schools can be conducted over longer periods of time (up to several hours) and are rolled out by a figure that is typically trusted and respected (the teacher). Moreover, intervening during adolescence is particularly timely since important vaccines are delivered at that age (most notably the human papillomavirus vaccine), and because attitudes towards vaccination during adolescence might have a long-lasting impact, as is the case for other health related attitudes. This study tests the effectiveness of two interventions, a pedagogical intervention based on consensus messaging, and a chatbot intervention designed to mimic interactive discussion, on 9th grade French pupils.

NCT ID: NCT06153576 Completed - Lymphoma Clinical Trials

The Value of Systematic Biopsies During Vertebroplasty for the Treatment of Osteoporotic Vertebral Fractures

Start date: January 1, 2016
Phase:
Study type: Observational

Background : Vertebral fracture is the most common complication of osteoporosis. Vertebroplasty is a widespread treatment modality for osteoporotic vertebral fractures, providing consolidation, rapid pain relief and preventing secondary vertebral collapse. Performing a biopsy at the same time as the operation does not lengthen the procedure or increase the risk of complications. The question therefore arises as to whether it is cost-effective diagnostically: are non-osteoporotic vertebral lesions detected when biopsies are taken? Methods: The investigators carried out a single-centre retrospective study at Nice University Hospital. From January 2016 to March 2022, 1729 biopsies were performed during 1439 vertebroplasty procedures on 1120 patients. The pre-operative laboratory work-up included a blood count, a C-reactive protein assay and a coagulation test. The imaging work-up systematically included MRI, unless contraindicated, in which case CT alone was performed. Vertebroplasty was performed in an interventional CT suite under dual CT and fluoroscopic guidance. The systematic biopsy sample was then sent to the anatomopathology department for analysis. Findings : The samples detected cancer in 35 patients, including 5 (0.44%) for whom the pre-operative work-up had not raised any suspicion. All the incidental findings were haemopathies, including 4 myelomas and one lymphoma. Conclusion : These results highlight the good performance of MRI in distinguishing osteoporotic vertebral fractures from solid tumour metastases. However, an exhaustive pre-operative work-up does not seem to be able to formally rule out an underlying malignant lesion. The investigators therefore recommend that biopsies be taken systematically when performing vertebroplasty.

NCT ID: NCT06153043 Completed - Clinical trials for Classic Congenital Adrenal Hyperplasia

Fertility and Pregnancy in Patients With Classic Congenital Adrenal Hyperplasia

FERTI-HCS
Start date: January 16, 2024
Phase:
Study type: Observational

Classic congenital adrenal hyperplasia (CAH) is a rare genetic endocrine disorder. Its prevalence is around 1/15.000. It results from a deficiency in 21-hydroxylase, an adrenal steroidogenic enzyme involved in the biosynthesis of cortisol and aldosterone. Enzyme deficiency in the steroideogenesis pathway leads to cortisol and aldosterone deficiency of varying severity, and to the accumulation of precursors (17OHP and Progesterone), which are diverted to the production of androgens (Testosterone and D4AD). There are two clinical forms of classical CAH : the salt wasting form and the simple virilizing form, depending on the degree of aldosterone deficiency. The clinical signs are adrenal insufficiency and hyperandrogenism. Hyperandrogenism manifests itself during foetal life, and may be responsible for virilization of the external genitalia of a female foetus, of varying severity. The challenge in managing this condition is to find the right therapeutic balance. Hydrocortisone and fludrocortisone supplementation must be adapted to control adrenal insufficiency, and limit hyperandrogenism. It must be sufficient to avoid episodes of acute adrenal insufficiency, but not excessive to avoid complications secondary to hypercorticism. During childhood, this balance is necessary for growth and pubertal development. However, this balance is difficult to achieve and maintain over time. In adulthood, the fertility of patients is an important issue. This one remains poorly understood. It was only after the introduction of cortisol supplementation in the treatment of CAH in the 1950s that the first pregnancies were described. Since when, due to the rarity of the pathology, the number of pregnancies studied has remained low, and the literature has little hindsight on the subject. This pathology has long been associated with female infertility, due to many factors : biological, mechanical, psychological and sexual, among others. Biological hyperandrogenism may be responsible for chronic dysovulation, and may render the endometrium unsuitable for embryonic implantation. The virilization of the external genitalia and possible complications of pelvic surgery can be an obstacle to sexuality in these patients. They experience sexual difficulties, particularly during penetrative intercourse. The literature also shows that the majority of these patients are single and that their sexual orientation is more likely to be homosexual. Finally, the desire to have children is less prevalent in these patients than in the general population. The first published studies on the fertility of CAH patients showed a lower pregnancy rate than the general population, but did not take into account the patient' desire to become pregnant. In 2009, Casteras et al demonstrated for the first time in a cohort of CAH patients that fecundity is preserved in patients with a desire to become pregnant. It should be noted that the fertility of patients with CAH may evolve in the coming years in France thanks to the new bioethics law voted in 2021, which now allows unmarried patients and patients in homosexual couples to have access to male gamete donation. In addition, very little is known about the course of pregnancies in patients with CAH. Few pregnancies have been studied to date. Hormonal balance during pregnancy if difficult to monitor, given the absence of reliable biological makers during this period. In this context, it is complicated to know the impact of the pathology and its balance on the course of the pregnancy. The latest articles published on the subject of pregnancy complications are contradictory. Some find an increased risk of gestational diabetes. Others find a higher risk of maternal-fetal infection, low weight for gestational age, or congenital malformations than in general population. The increased risk of miscarriage is debated. On the other hand, articles are unanimous on the most frequent mode of delivery in this population : in the vast majority of cases, patients give birth by ceasarian section, due to their history of pelvic surgery. It is in context that we wish through this study to make a point of fertility and pregnancy in patients with classical CAH.
