Background: Video laryngoscopy is beneficial in difficult airway intubation; however, various factors complicate the process. These devices come in different designs, and their usefulness may vary by type. In this study, we compared the effectiveness of several video laryngoscopic .instruments across three simulated difficult intubation scenarios using manikin models. Methods: Training simulators for tracheal intubation were set to four conditions: (i) Normal (mouth opening:50 mm, normal neck); (ii) Head tilt disorder (mouth opening: 50 mm, rigid neck); (iii) Trismus (mouth opening:20 mm, normal neck); and (iv) Head tilt disorder + trismus (mouth opening: 20 mm, rigid neck). Seventeen dental anesthesiologists attempted oral tracheal intubation using the following video laryngoscopes: Airway Scope;McGRATH (Normal blade [size 3]); McGRATH (X-blade); and i-view. Evaluated parameters included total intubation time, glottic visualization time, tube induction time, success rate, and difficulty grading of tracheal intubation (Cormack-Lehane classification and the Numerical Rating Scale [NRS]). Statistical analysis was conducted using mixed models, incorporating two-way ANOVA, Tukey’s test, two-way ANOVA without repeated measures, and Kruskal-Wallis test, with P < 0.05 deemed statistically significant. Results: Intubation time using i-view was significantly longer for head tilt disorder and trismus compared to other video laryngoscopes (head tilt disorder: P < 0.001 for all, trismus: P = 0.021 vs. Airway Scope, P = 0.028 vs. X-blade). The Cormack-Lehane grade was notably high (P = 0.001) for tracheal intubation with i-view in the head tilt disorder scenario, with intubation failing in three cases. In the combined situation of head tilt disorder and trismus, intubation time with Airway Scope was shorter (P < 0.001 vs. X-blade), achieving a success rate of 100%. However, all attempts with i-view were unsuccessful. The NRS score was significantly higher for i-view compared to the other video laryngoscopes (P < 0.001). Conclusion Video laryngoscopy effectiveness varies by type in difficult tracheal intubation cases. The Airway Scope or McGRATH instrument appears more suitable for such cases, as indicated by the metrics of intubation time, success rate, and difficulty level.

Objective: To implement early rehabilitation interventions by physical therapists is recommended. However, the effectiveness of early rehabilitation for severe coronavirus disease 2019 (COVID-19) patients in the prevention of post-intensive care syndrome (PICS) is unclear. We analyzed a multicenter prospective observational study (Post-Intensive Care outcomeS in patients with COronaVIrus Disease 2019) to examine the association between early rehabilitation interventions and PICS physical impairment. Methods: An analysis was performed on COVID-19 patients who were admitted to intensive care units (ICUs) between March 2020 and March 2021, and required mechanical ventilation. The primary outcome was the incidence of PICS physical impairment (Barthel Index≤90) after one year. Multivariate logistic regression analysis was used to estimate the association between early rehabilitation interventions and PICS physical impairment by adjusting ICU mobility scale (IMS) during seven-day following ICU admission, and clinically relevant risk factors. Results: The analysis included 259 patients, 54 of whom developed PICS physical impairment one year later. In 81 patients, physical therapists intervened within seven days of ICU admission. There was no significant difference in mean IMS by day seven of admission between the early and non-early rehabilitation patients (0.70 and 0.61, respectively). Multivariate logistic regression analysis showed that early rehabilitation interventions were significantly associated with a low incidence of PICS physical impairment (odds ratio, 0.294; 95% confidence interval, 0.123–0.706; p=0.006). Conclusion Early rehabilitation interventions by physical therapists were an independent factor associated with the decreased development of PICS physical impairment at one year, even though early rehabilitation had no significant effect on IMS.

Neuropathic pain is a chronic condition caused by damage or dysfunction in the nervous system. While the spleen may influence neuropathic pain, its role has been poorly understood. This study demonstrates that the spleen plays a crucial role in regulating neuropathic pain through the bed nucleus of the stria terminalis (BNST) - paraventricular nucleus of the hypothalamus (PVN) neural circuit in a chronic constriction injury (CCI) mouse model. Splenectomy, splenic denervation, or splenic sympathectomy significantly increased the mechanical withdrawal threshold (MWT) and reduced macrophage infiltration in the dorsal root ganglia (DRG) of CCI mice. Pseudorabies virus injections into the spleen revealed connections to the BNST and PVN in the brain. Chemogenetic inhibition of the BNST-PVN circuit increased macrophage infiltration in the DRG and decreased the MWT; these effects were reversed by splenectomy, splenic denervation, or sympathectomy. These findings underscore the critical role of the spleen, regulated by the BNST-PVN circuit, in neuropathic pain.
