The production of ethylene glycol (EG) from cellulose has garnered significant attention in recent years as an attractive alternative to fossil fuels due to the potential of cellulose as a renewable and sustainable feedstock. In this work, to the best of our knowledge, a series of low-cost Ni-W bimetallic catalysts supported on glucose/carbon nanotube hybrid carbons were synthesised for the first time and employed to transform cellulose into EG. Two different strategies were combined for the preparation of the carbons: the activation and addition of carbon nanotubes (CNTs) to obtain a hybrid material (AG-CNT).

Article Synopsis
  • The study aimed to assess swallowing in patients who had CO2 LASER Partial Epiglottectomy for Obstructive Sleep Apnea Syndrome and evaluate any risks of aspiration post-surgery.
  • Researchers reviewed the charts of eight adult patients who underwent the procedure from 2016 to 2020, conducting swallowing evaluations via questionnaires and tests 6 months after surgery.
  • Results showed that while some patients had minor swallowing issues, there were no significant safety concerns, suggesting CO2-LPE is a safe treatment for patients with epiglottic collapse related to obstructive sleep apnea.

Unilateral vocal fold paralysis (UVFP) is a frequent finding in otorhinolaryngology practice, but its occurrence as a port complication was very rarely described in English Literature. The authors report a 55-year-old woman with a pancreatic adenocarcinoma who presented a left vocal fold paralysis that occurred concurrently with a venous thrombosis of the left subclavian vein, where a totally implantable venous-access had been previously placed. Although the patient's oncologic disease, that could mislead to a neoplastic cause of the UVFP, the authors came across with an unusual etiology and to their best knowledge, it is the first case of irreversible UVFP associated with onsite thrombosis of the vessel where a port was implanted.
