Awake nasotracheal intubation with a 300-mm working length fiberscope: a prospective observational feasibility trial
Background: Awake fiberoptic tracheal intubation is an established method of securing difficult airways, but there are some reservations about its use because many practitioners find it technically complicated, time-consuming, and unpleasant for patients. Our main goal was to test the safety and efficacy of a 300-mm working length fiberscope (video rhino-laryngoscope) when used for awake nasotracheal intubation in difficult airway cases. Methods: This was a prospective, single-center study involving adult patients, having an ASA physical status between I and IV, with laryngopharyngeal pathology causing distorted airway anatomy. Awake nasotracheal intubation, using topical anesthesia and light sedation, was performed using a 300 mm long and 2.9 mm diameter fiberscope equipped with a lubricated reinforced endotracheal tube. The primary outcomes were the success and duration of the procedure. Patients’ periprocedural satisfaction and other incidents were recorded. Results: We successfully intubated all 25 patients included in this study. The mean ±SD duration of the procedure, starting from the passage of the intubating tube through one of the nostrils until the endotracheal intubation, was 76 ± 36 seconds. Most of the patients showed no discomfort during the procedure with statistical significance between the No reaction Group with the Slight grimacing Group (95%CI 0.13, 0.53, p = 0.047) and the Heavy grimacing Group (95%CI 0.05, 0.83, p = 0.003). The mean ±SD satisfaction score 24 hours post-intervention was 1.8 ± 0.86 – mild discomfort. No significant incidents occurred. Conclusions: Our study showed that a 300-mm working length flexible endoscope is fast, safe, and well-tolerated for nasotracheal awake intubation under challenging airways
Clinical Experiences with the FRONT Formula for Pre-Operative Airway Assessment and Documentation: a Multi-Centre Study
Objective: The prediction of difficult airway is one of the most important challenges before general anaesthesia. This study aimed to assess the clinical usefulness of the FRONT score, a recently developed scoring system to predict and document airway difficulties.
Methods: This multi-centre, inter-observer, prospective and double-blinded study included 976 patients from two university centres. The pre-operative evaluation of the patients was performed by a pre-operative team of anaesthesiologists (team A) who evaluated and scored the expected difficulty of airway management. An intra-operative team of evaluators (team B) working independently of team A, performed the actual instrumentation of the airway and scored the actual findings. Both teams used the FRONT scoring system and worked independently of each other to ensure blinded assessments. The statistical analysis of the pre- and intra-operative FRONT scores was performed in an off-line blinded manner.
Results: Our results show a fair and promising association between pre-operative composite FRONT score and that observed at the induction phase (Spearman=0.43). Among the score components, the best correlation was observed for the F and R components (kappa=0.44 and 0.36, respectively), and the worse correlation was observed for the O and T components (kappa=0.25 and 0.24, respectively).
Conclusion: The FRONT formula for the prediction and documentation of the airway status is a simple and effective method for assessing and defining airway management difficulties. Further prospective studies are required to assess the sensitivity and specificity of the system

The Multifaceted Role and Regulation of Nlrp3 Inflammasome in Colitis-Associated Colo-Rectal Cancer: A Systematic Review
Colitis-associated colo-rectal cancer remains the leading cause of mortality in inflammatory bowel diseases, with inflammation remaining one of the bridging points between the two pathologies. The NLRP3 inflammasome complex plays an important role in innate immunity; however, its misregulation can be responsible for the apparition of various pathologies such as ulcerative colitis. Our review focuses on the potential pathways of upregulation or downregulation of the NLRP3 complex, in addition to evaluating its role in the current clinical setting. Eighteen studies highlighted the potential pathways of NLRP3 complex regulation as well as its role in the metastatic process in colo-rectal cancer, with promising results. Further research is, however, needed in order to validate the results in a clinical setting
