Study Objective: To compare the use of the I-gel airway with orotracheal intubation (OTI) for bronchoscopic lung volume reduction (BLVR) coil treatment in patients with severe chronic obstructive pulmonary disease (COPD) with heterogeneous emphysema, since it has been proved that supraglottic airways have lower incidence of postoperative respiratory complaints compared to OTI.
Design: A comparative, prospective observational study was designed to assess the use of the I-gel airway compared with the OTI.
Setting: Bronchoscopy room at the University Hospital Fundación Jimenez Diaz, Madrid. Tertiary care center.
Patients: Thirty-three procedures were carried out in 22 patients diagnosed with COPD with severe heterogeneous emphysema undergoing BLVR coil treatment under general anaesthesia.
Intervention: Seventeen procedures were carried out with I-gel and 16 with endotracheal tube. Airway device choice was left to the attendant anesthesiologist.
Measurements: Tidal volume, peak pressure, and the presence of gas leaks were compared. Adverse events during the procedure and within the first 3 hours later were also recorded.
Main Results: Ventilation parameters obtained showed no significant differences. Mean tidal volume was 466.6 ± 28.2 mL and 478.7 ± 34.0 mL (P > .05), mean peak pressure was 17.9 ± 2.5 cmH2O and 19.4 ± 2.4 cmH2O (P > .05) and mean gas leaks was 71 ± 17.6 mL and 79 ± 15.5 mL (P > .05) for I-gel group (IgelG) and endotracheal tube group respectively. No serious complications were reported. One case of pneumothorax was reported in the endotracheal tube group, which was resolved with a chest drainage tube without further complications.
Conclusion: The I-gel airway ensures appropriate ventilation and makes the use of the flexible fiberoptic bronchoscope quite easy. Therefore, we consider that the I-gel device is an effective and safe alternative to classical OTI for airway management in COPD patients with severe heterogeneous emphysema undergoing BLVR coil treatment.

Undocking of an extensive ciliary network induces proteostasis and cell fate switching resulting in severe primary ciliary dyskinesia.

Article Synopsis
- Primary ciliary dyskinesia (PCD) is a rare genetic disorder linked to chronic respiratory issues, infertility, and problems with body asymmetry, primarily caused by mutations in the CCDC39 and CCDC40 genes.
- Researchers used advanced techniques to investigate how these genetic variants impact cellular functions beyond just causing cilia to stop moving.
- They discovered that the absence of CCDC39/CCDC40 creates a significant loss of over 90 ciliary structural proteins, leading to cilia dysfunction and other cellular issues, suggesting that gene therapy could potentially offer a new treatment strategy for PCD.
Addressing residual and recurrent aneurysms post-Woven EndoBridge device embolization: a systematic review and meta-analysis.

Background: Early literature on the Woven EndoBridge (WEB) device reported 80-90% adequate aneurysm occlusion but low complete occlusion (40-55%). It is uncertain whether residual or recurrent aneurysms require re-treatment to prevent future rupture.
Objective: To systematically review the literature to meta-analyze occlusion and complication rates after re-treatment of these aneurysms.

Male infertility is a multifactorial condition for which the underlying causes frequently remain undefined. Genetic factors have long been associated with male fertility. However, many of them are poorly or not at all characterized and their biological functions are unknown.

The combination of polyphenols and protein can improve the functional characteristics of protein. How to effectively promote the binding of polyphenols to protein is still a difficult topic. In this study, hydrodynamic cavitation (HC) was used to induce the fabrication of complexes between soy protein isolate (SPI) and different polyphenols (tannic acid (TA), chlorogenic acid (CGA), ferulic acid (FA), caffeic acid (CA), and gallic acid (GA)).
