Background: Peri-operative respiratory adverse events (PRAEs) in paediatric patients with upper respiratory tract infections (URTIs) remain inadequately explored in patients allowed to proceed to anaesthesia and surgery.
Objective: To determine the incidence and risk factors of PRAE in children with URTI allowed to proceed to anaesthesia.
Design: Multicentre cohort study performed over 6 months in France.
Setting: Sixteen centres with dedicated paediatric anaesthetists.
Patients: Eligible patients were aged from 0 to 18 years with URTI symptoms on admission or a history of such over the preceding 4 weeks.
Main Outcomes: The primary outcome of the study was to determine predictors of PRAE. Secondary outcomes were: predictors of peri-operative arterial desaturation and of the decision to proceed with anaesthesia and surgery in children with URTI.
Results: Overall, 621 children were included and 489 (78.7%) anaesthetised. Of those anaesthetised, 165 (33.5%) and 97 (19.8%) experienced PRAE and arterial desaturation, respectively. Factors predictive of PRAE included patient age, tracheal intubation and the absence of midazolam premedication. Factors predictive of peri-operative arterial desaturation included patient age, anaesthetist experience, endoscopic procedures and the presence of other PRAE. Factors predicting proceeding to anaesthesia in the context of URTI included anaesthetist experience, emergency procedures and the absence of severe URTI symptoms.
Conclusion: The risk of PRAE in patients anaesthetised in the presence of URTI was similar to previous publications - close to 30%. In the light of our findings, first, current rescheduling indications should be questioned, and second, further medical and organisational strategies should be investigated to reduce PRAE in children with URTI.
Trial Registration: The study was registered in the European Networks of Centers for Pharmacoepidemiology and Pharmacovigilance (EUPAS16436).

Polyethers are versatile materials extensively used in advanced as well as everyday applications. The incorporation of primary amine functionality into polyethers is particularly attractive due to its well-established coupling chemistries. However, the inherent nucleophilicity of amine group poses a challenge in the anionic ring-opening polymerization (ROP) of epoxides and requires the use of robust protecting groups that can withstand the harsh conditions of ROP without triggering undesirable side reactions.

The selective insertion of membrane-impermeant amphiphiles such as detergents, (lipo)peptides, drugs, etc. into the leaflet of a membrane causes an imbalance between the intrinsic areas of the and leaflet, referred to as asymmetry stress or differential stress. The literature provides individual mechanisms of how membranes respond to such stress, which are relevant to membrane remodeling processes and leakage phenomena.

Despite the growing importance of planar chiral macrocyclophanes owing to their unique properties in different areas of chemistry, methods that are effective in controlling their planar chirality are restricted to certain molecular scaffolds. Herein, we report the first Pd(0)-catalyzed enantioselective intermolecular C-H arylation that induces planar chirality by installing bulky aryl groups through dynamic kinetic resolution (DKR). A computer-assisted approach allowed a fine-tuning of the structure of the employed chiral bifunctional phosphine-carboxylate ligands to achieve high enantioselectivities.

Heterogeneous catalysts are pivotal to the chemical and energy industries, which are central to a multitude of industrial processes. Large-scale industrial catalytic processes rely on special structures at the nano- or atomic level, where reactions proceed on the so-called active sites of heterogeneous catalysts. The complexity of these catalysts and active sites often lies in the interfacial regions where different components in the catalysts come into contact.

Despite the evident demand and promising potential of disulfide-functionalized amino acids and peptides in linker chemistry and peptide drug discovery, those disulfurated specifically at the α-position constitute a unique yet rather highly underexplored chemical space. In this study, we have developed a method for preparing -linked amino acid/peptide derivatives through a base-catalyzed disulfuration reaction of azlactones, followed by the ring-opening functionalization. The disulfuration reaction proceeds under mild conditions, yielding disulfurated azlactones in excellent yields across a variety of -dithiophthalimides and diverse azlactones derived from various amino acids and peptides.
