Objectives: To prospectively assess, using polysomnography (PSG), the evolution in obstructive sleep apnea (OSA) in infants with Robin Sequence (RS) during their first year of life and to evaluate the role of PSG in OSA treatment.
Methods: Prospective and longitudinal study conducted in 2 tertiary hospitals (2018-2021). Data from 2 PSG (PSG1 0-3 months of life, PSG2 6-10 months of life) performed in RS infants in different sleep positions/conditions (without treatment: supine [SP]; with treatment: lateral [LP], prone [PP], respiratory support) were analyzed.
This paper describes the development of a novel medical x-ray imaging system adapted to the needs and constraints of low- and middle-income countries. The developed system is based on an indirect conversion chain: a scintillator plate produces visible light when excited by the x rays, and then, a calibrated multi-camera architecture converts the visible light from the scintillator into a set of digital images. The partial images are then unwarped, enhanced, and stitched through parallel field programmable gate array processing units and specialized software.

The objectives of the present study were to assess the prevalence of abnormal oral glucose tolerance test (OGTT) at 3 months of age in infants operated at birth with type C OA, to describe symptoms and clinical features, and to assess risk factors in infants presenting with abnormal OGTT suggestive of DS.
Methods: A prospective case series study including infants with type C OA without fundoplication, born between 2013 and 2016 in 8 centres was conducted.
Objective: To identify predictors of and factors associated with the performance of antireflux surgery during the first year of life in children born with esophageal atresia.
Study Design: All patients were included in a French registry for esophageal atresia. All 38 multidisciplinary French centers completed questionnaires about perinatal characteristics and one-year outcome for children born with esophageal atresia.
Free fatty acid-2 (FFA2) receptor is a G-protein coupled receptor of interest in the development of therapeutics in metabolic and inflammatory disease areas. The discovery and optimization of an N-thiazolylamide carboxylic acid FFA2 agonist scaffold is described. Dual key objectives were to i) evaluate the potential of this scaffold for lead optimization in particular with respect to safety de-risking physicochemical properties, i.

Objective: To compare the rate of complications, and functional and anatomical outcomes between LS and TVM.
Objective: To evaluate the status of congenital diaphragmatic hernia (CDH) management in France and to assess predictors of adverse outcomes.
Study Design: We reviewed the first-year outcome of all cases of CDH reported to the French National Register in 2011.
Results: A total of 158 cases were included.
Kasabach-Merritt phenomenon can be encountered in the perinatal period. No consensus exists regarding prenatal management. We report one prenatal case leading to therapeutic abortion and one neonatal case, successfully treated by a multimodal therapy.
View Article and Find Full Text PDFNeurokinin-3 receptor (NK3R) has recently emerged as important in modulating the tonic pulsatile gonadotropin-releasing hormone (GnRH) release. We therefore decided to explore NK3R antagonists as therapeutics for sex-hormone disorders that can potentially benefit from lowering GnRH pulsatility with consequent diminished levels of plasma luteinizing hormone (LH) and correspondingly attenuated levels of circulating androgens and estrogens. The discovery and lead optimization of a novel N-acyl-triazolopiperazine NK3R antagonist chemotype achieved through bioisosteric lead change from the high-throughput screening (HTS) hit is described.

Methods: All 38 multidisciplinary French centers that care for patients with EA returned a specific questionnaire about the 1-year outcome for each patient. This information was centralized, checked, and entered into a database.
Objectives: High-fidelity simulation is an effective tool in teaching neonatal resuscitation skills to professionals. We aimed to determine whether in situ simulation training (for ∼80% of the delivery room staff) improved neonatal resuscitation performed by the staff at maternities.
Methods: A baseline evaluation of 12 maternities was performed: a random sample of 10 professionals in each unit was presented with 2 standardized scenarios played on a neonatal high-fidelity simulator.
Tsitsikammamines are marine alkaloids whose structure is based on the pyrroloiminoquinone scaffold. These and related compounds have attracted attention due to various interesting biological properties, including cytotoxicity, topoisomerase inhibition, antimicrobial, antifungal and antimalarial activity. Indoleamine 2,3-dioxygenase (IDO1) is a well-established therapeutic target as an important factor in the tumor immune evasion mechanism.

With the aim of discovering novel IDO inhibitors, a virtual screen was undertaken and led to the discovery of the keto-indole derivative 1a endowed with an inhibitory potency in the micromolar range. Detailed kinetics were performed and revealed an uncompetitive inhibition profile.

View Article and Find Full Text PDFIndoleamine 2,3-dioxygenase (IDO) is a heme dioxygenase which has been shown to be involved in the pathological immune escape of diseases such as cancer. The synthesis and structure-activity relationships (SAR) of a novel series of IDO inhibitors based on the indol-2-yl ethanone scaffold is described. In vitro and in vivo biological activities have been evaluated, leading to compounds with IC(50) values in the micromolar range in both tests.
View Article and Find Full Text PDFSuccess in discovering bioactive peptide mimetics is often limited by the difficulties in correctly transposing known binding elements of the active peptide onto a small and metabolically more stable scaffold while maintaining bioactivity. Here we describe a scanning approach using a library of pyranose-based peptidomimetics that is structurally diverse in a systematic manner, designed to cover all possible conformations of tripeptide motifs containing two aromatic groups and one positive charge. Structural diversity was achieved by efficient selection of various chemoforms, characterized by a choice of pyranose scaffold of defined chirality and substitution pattern.

Efforts are underway to screen selective modulators of GPCRs and also to deorphanize GPCRs with unidentified natural ligands. Most GPCR-based cellular screens depend on labeling or recombinant expression of receptor or reporter proteins, which may not capture the true physiology or pharmacology of the GPCRs.
