Objective: To compare the efficacy of a three-dimensional (3D) haptic interface to a two-dimensional (2D) mouse interface for a screen-based simulation (SBS) neonatal intubation (NI) training intervention. Primary hypothesis: a haptic interface is more effective than a mouse interface for SBS training intervention for NI. Secondary hypothesis: SBS training, regardless of interface, will result in improved NI performance on a neonatal airway simulator.

Methods: 45 participants were randomised to either a haptics or a mouse interface to complete an identical SBS training intervention for NI over a five-month period. Participants completed pre- and post-training surveys to assess demographics, experience, knowledge and attitudes. The primary outcome of participants' NI skills performance was assessed on a neonatal manikin simulator. Skills were measured pre- and post- training by number of attempts and time to successfully intubate, and airway visualization.

Results: The demographics, training and experience were similar between groups. There was no difference in the improvement in skills, knowledge, attitudes or satisfaction ratings pre- and post-training between the groups. There was a significant decrease in number of attempts to intubate a neonatal airway simulator (2.89 vs 1.96, p<0.05) and improvement in the percent of subjects intubating in <30 seconds (22% vs 27%, p=0.02) from pre- to post-training in the study population overall.

Conclusion: Using a haptic interface did not have an advantage over a mouse interface in improving NI skills, knowledge, attitudes, or satisfaction. Overall, a SBS training intervention for NI improved skills measured on a neonatal airway simulator.

Optimizing the design of nanoparticulate co-delivery systems of antigens and immunomodulators to induce antigen-specific immune tolerance effectively remains a challenge, constrained by low drug loading capacity and premature leakage of active ingredients. Here, we report a prodrug self-assembled nanoparticles (NPs) strategy to synergistically deliver antigen and rapamycin (RAPA) into antigen-presenting cells (APCs) by simply conjugating rapamycin with an aliphatic chain. These prodrug NPs can be efficiently taken up by APCs and then release rapamycin through cleavage of the linker by intracellular esterase.

Electrostatic Force-Enabled Microneedle Patches that Exploit Photoredox Catalysis for Transdermal Phototherapy.

Beijing National Laboratory for Molecular Sciences, College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, China.

Microneedle patches for topical administration of photodynamic therapy (PDT) sensitizers are attractive owing to their safety, selectivity, and noninvasiveness. However, low-efficiency photosensitizer delivery coupled with the limitations of the hypoxic tumor microenvironment remains challenging. To overcome these issues, we developed an effective microneedle patch based on intermolecular electrostatic interactions within a photosensitizer matrix containing a zinc-containing porphyrin analogue, .

Hyaluronan-modified nanoceria for dry eye disease treatment.

Electronic address:

Dry eye disease (DED), a prevalent ocular disorder, affects nearly half the global population, bringing enormous health and economic burden. Currently, the predominant treatments for DED involve the administration of artificial tears, which is often hindered by continuous administration and constant reactive oxygen species (ROS) stimulus. Therefore, hyaluronan (HA)-modified cerium oxide (CeO) nanoparticles, HA-CeO, were developed to achieve simultaneous ROS scavenging and enhanced tear film stability.

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is an important environmental pollutant that disturbs the immune balance of the maternal-fetal interface (MFI) and is also a common environmental factor for the formation of cleft palate (CP). Therefore, the purpose is to investigate whether TCDD can cause CP by disrupting the immune balance of the maternal-fetal interface. Fifteen C57BL/6J mice were randomly assigned to three groups: control group, TCDD group, and TCDD plus Freund's complete adjuvant (FCA) (TCDD + FCA) group.

: The objective of this paper is to introduce a method to measure the force or pressure over the carpal tunnel indirectly, using a new device to drive the pointer of a computer system. The measurements were compared with those obtained using an ergonomic mouse. Simultaneously, measurements of muscular stress on the digitorum extensor muscle were performed to correlate the applied force against muscle activity.
