Evaluation of pelvic floor rehabilitation in the prevention of low anterior resection syndrome: Study protocol of the CONTICARE trial.

Aim: Bowel dysfunction following sphincter-preserving rectal resection for cancer, commonly referred to as low anterior resection syndrome (LARS), significantly impacts patients' quality of life. Preventing this condition is essential for healthcare teams. Postoperative pelvic floor rehabilitation, including anal biofeedback therapy, has shown potential in alleviating established LARS symptoms.

Changes in microcirculation following transcatheter aortic valve implantation in patients with stable coronary artery disease.

Background: Few studies have assessed coronary physiology in the setting of coronary artery disease (CAD) with severe aortic stenosis (AS). Fractional flow reserve (FFR) to guide revascularization in such patients is not validated.

Aims: We describe changes in coronary physiology in this population before and after transcatheter aortic valve implantation (TAVI).

Learning curves of novice residents on cataract surgery simulator: the E3CAPS pedagogic study.

Introduction: Training novice ophthalmology residents on the EyeSi simulator increases cataract surgery safety. However, there is no consensus regarding how much training residents should perform before their first time on patients. We evaluated the French national training program through the analysis of the learning curves of novice residents.

Pros and cons of internal limiting membrane peeling during epiretinal membrane surgery: a randomised clinical trial with microperimetry (PEELING).

Background: After idiopathic epiretinal membrane (iERM) removal, it is unclear whether the internal limiting membrane (ILM) should be removed. The objective was to assess if active ILM peeling after iERM removal could induce microscotomas.

Methods: The PEELING study is a national randomised clinical trial.

Efficacy of Spironolactone Compared with Doxycycline in Moderate Acne in Adult Females: Results of the Multicentre, Controlled, Randomized, Double-blind Prospective and Parallel Female Acne Spironolactone vs doxyCycline Efficacy (FASCE) Study.

Acne in adult females is triggered mainly by hormones. Doxycycline is a reference treatment in acne. Spironolactone targets the androgen receptor of sebaceous glands and is prescribed off-label for female adult acne.

Insulin Growth Factor-1 Status in Hidradenitis Suppurativa: A French Institutional Pilot Study.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease of the follicles in the apocrine glands and is associated with a deficiency in the innate immunity of the skin. It is characterized by the occurrence of nodules, abscesses, fistulas, scars.

Objective: Although a relationship has already been demonstrated between HS and innate immunity, IGF-1 status in patients with HS is still unknown.

Long-term benefits of a therapeutic make-up consultation for patients with various facial dermatoses.

Background: Therapeutic make-up has previously been proven to be efficacious in improving the quality of life of patients with facial dermatoses, but its efficacy has only been assessed in the short term (less than one month).

Objectives: This study aimed to determine whether the effect of therapeutic make-up on patients' quality of life persists in the longer term, i.e.

Educational Concerns About the Safety of Cataract Surgery During Residency: The E3CAPS Pedagogic Study.

Introduction: Cataract surgery is the most common surgical procedure performed in France. While the incidence of intraoperative complications affecting visual prognosis is extremely low, given the large number of patients operated on, the absolute number of patients affected by complications is quite high. Complication rates are significantly higher when ophthalmology residents (ORs) perform the surgery.

Panniculitis does not predict clinical response in patients with advanced melanoma under targeted therapy.

Background: BRAF and MEK inhibitors have changed the landscape of treatment for advanced melanoma. Among their side effects, panniculitis has been hypothesized to be associated with better survival.

Objectives: In this study, we aimed to explore the association between the occurrence of panniculitis during targeted therapy and outcome of metastatic melanoma.

PROPERTY: study protocol for a randomized, double-blind, multicenter placebo-controlled trial assessing neurotoxicity in patients with metastatic gastrointestinal cancer taking PHYCOCARE® during oxaliplatin-based chemotherapy.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common adverse effects of antineoplastic agents, ranging in prevalence from 19% to over 85%. Clinically, CIPN is a predominantly sensory neuropathy that may be accompanied by motor and autonomic changes of varying intensity and duration. The high prevalence of CIPN among cancer patients makes it a major problem for both patients and survivors, as well as for their health care providers, especially because there is currently no single effective method of preventing CIPN; moreover, the options for treating this syndrome are very limited.

What is new in adult acne for the last 2 years: focus on acne pathophysiology and treatments.

Acne affects more than 640 million people worldwide, including about 85% of adolescents. This inflammatory dermatosis affects the entire population, from teenagers to adults, which reinforces the need to investigate it. Furthermore, in adults, acne has serious consequences, including a psychological impact, low self-esteem, social isolation, and depression.

Evaluation of the safety and efficacy of XAV-19 in patients with COVID-19-induced moderate pneumonia: study protocol for a randomized, double-blinded, placebo-controlled phase 2 (2a and 2b) trial.

Background: Early inhibition of entry and replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a very promising therapeutic approach. Polyclonal neutralizing antibodies offers many advantages such as providing immediate immunity, consequently blunting an early pro-inflammatory pathogenic endogenous antibody response and lack of drug-drug interactions. By providing immediate immunity and inhibiting entry into cells, neutralizing antibody treatment is of interest for patient with COVID-19-induced moderate pneumonia.

FASCE, the benefit of spironolactone for treating acne in women: study protocol for a randomized double-blind trial.

Background: Acne vulgaris has increased in women over the past 10 years; it currently affects 20-30% of women. The physiopathology of adult female acne is distinguished from that of teenagers essentially by two factors: hormonal and inflammatory. On a therapeutic plan, the four types of systemic treatment approved for female acne include cyclines (leading to bacterial resistance); zinc salts (less effective than cyclines); and antiandrogens (risks of phlebitis).

Does internal limiting membrane peeling during epiretinal membrane surgery induce microscotomas on microperimetry? Study protocol for PEELING, a randomized controlled clinical trial.

Background: The epiretinal membrane (ERM) is a degenerative condition associated with age, which can cause loss of vision and/or metamorphopsia. The treatment of symptomatic ERM involves surgical removal including a vitrectomy followed by peeling of the ERM using a microforceps. As the internal limiting membrane (ILM) is adherent to the ERM, it is sometimes removed with it (spontaneous peeling).

Impact of fecal microbiota transplantation on chronic recurrent pouchitis in ulcerative colitis with ileo-anal anastomosis: study protocol for a prospective, multicenter, double-blind, randomized, controlled trial.

Background: Almost 15% of patients with ulcerative colitis (UC) will require a proctocolectomy with ileal pouch-anal anastomosis (IPAA) as a result of fulminant colitis, dysplasia, cancer, or medical refractory diseases. Around 50% will experience pouchitis, an idiopathic inflammatory condition involving the ileal reservoir, responsible for digestive symptoms, deterioration in quality of life, and disability. Though the majority of initial cases of pouchitis are easily managed with a short course of antibiotics, in about 10% of cases, inflammation of the pouch becomes chronic with very few treatments available.

VALIDation of the IBD-Disk Instrument for Assessing Disability in Inflammatory Bowel Diseases in a French Cohort: The VALIDate Study.

Background And Aims: Inflammatory bowel diseases [IBD] are disabling disorders. The IBD-Disability Index [IBD-DI] was developed for quantifying disability in IBD patients but is difficult to use. The IBD-Disk is a visual adaptation of the IBD-DI.

Comparison of two techniques used in routine care for the treatment of inflammatory macular oedema, subconjunctival triamcinolone injection and intravitreal dexamethasone implant: medical and economic importance of this randomized controlled trial.

Background: Whether they are injected peri- or intraocularly, corticosteroids are still essential tools in the therapeutic arsenal for treating inflammatory macular oedema. A few years ago, however, only triamcinolone acetonide was available to ophthalmologists. While this compound was initially developed for rheumatological or dermatological use, it has been increasingly deployed in ophthalmology, despite still being off-label.

Foetal skin cells in wound healing: a promising tool for clinical application.

The skin is the first protective barrier of our body. Wound healing is therefore an essential mechanism. However, this phenomenon can be impaired when wounds are too large or chronic, for example, in diabetes.

CICAFAST: comparison of a biological dressing composed of fetal fibroblasts and keratinocytes on a split-thickness skin graft donor site versus a traditional dressing: a randomized controlled trial.

Background: Wound repair is one of the most complex biological processes of human life. Allogeneic cell-based engineered skin substitutes provide off-the-shelf temporary wound coverage and act as biologically active dressings, releasing growth factors, cytokines and extracellular matrix components essential for proper wound healing. However, they are susceptible to immune rejection and this is their major weakness.

[Successful completion of an ISO 9001 v 2015 certification process in clinical investigation research].

Unlabelled: Clinical investigation at the University Hospital of Nantes is carried out within the investigation department, which consists of coordination and 24 clinical research teams gathered at four different hospital sites. The Clinical Investigation Units are all equipped with a Quality Management System. This has been in place for more than 12 years and was initially created for the Clinical Investigation Units of the Clinical Investigation Centre (CIC 1413) in Nantes and then transposed in 2013, to the emerging Clinical Investigation Units.

The cyclization of the 3,6-anhydro-galactose ring of iota-carrageenan is catalyzed by two D-galactose-2,6-sulfurylases in the red alga Chondrus crispus.

Carrageenans are sulfated galactans found in the cell walls of numerous red seaweeds (Rhodophyta). They are classified according to the number and the position of sulfate ester groups and the occurrence of 3,6-anhydro-galactose. Although the carrageenan biosynthesis pathway is not fully understood, it is usually accepted that the last step consists of the formation of a 3,6-anhydro ring found in kappa- and iota-carrageenans through the enzymatic conversion of d-galactose-6-sulfate or d-galactose-2,6-disulfate occurring in mu- and nu-carrageenan, respectively.

Interaction of the catalytic domain of inositol 1,4,5-trisphosphate 3-kinase A with inositol phosphate analogues.

The levels of inositol 1,4,5-trisphosphate [Ins(1,4,5)P3] in the cytoplasm are tightly regulated by two enzymes, Ins(1,4,5)P3 3-kinase and type I Ins(1,4,5)P3 5-phosphatase. The catalytic domain of Ins(1,4,5)P3 3-kinase (isoenzymes A, B and C) is restricted to approximately 275 amino acids at the C-terminal end. We were interested in understanding the catalytic mechanism of this key family of enzymes in order to exploit this in inhibitor design.
