Apnoeic oxygenation in morbid obesity: a randomised controlled trial comparing facemask and high-flow nasal oxygen delivery.

Background: Obesity is a risk factor for airway-related incidents during anaesthesia. High-flow nasal oxygen has been advocated to improve safety in high-risk groups, but its effectiveness in the obese population is uncertain. This study compared the effect of high-flow nasal oxygen and low-flow facemask oxygen delivery on duration of apnoea in morbidly obese patients.

Purification and Partial Characterization of Peroxidases from Three Food Waste By-Products: Broad Bean Pods, Pea Pods, and Artichoke Stems.

In this study, peroxidases (PODs) from three waste by-products: broad bean pods (BBP), pea pods (PP), and artichoke stems (ARS) were purified and their optimal conditions were determined for the first time. The purification process resulted in 4.32, 7.

The use of high-dose intrathecal diamorphine in laparoscopic bariatric surgery: a single-centre retrospective cohort study.

Introduction: The use of intrathecal diamorphine is not commonplace in laparoscopic bariatric surgery. At our institution, a major UK bariatric centre, high-dose intrathecal diamorphine is routinely utilised.

Methods: Data were analysed retrospectively.

Development of a flow injection analytical system for short chain amide determination based on a tubular bioreactor and an ammonium sensor.

Pseudomonas aeruginosa (P. aeruginosa) possesses intracellular amidase activity, which catalyses the hydrolysis of short aliphatic amides producing NH4+, and has already been used along with an ammonium ion selective electrode for amide quantification. However, the incorporation of a biological membrane turned to be a challenging process and either the final arrangement was prone to amidase losses or the recovery of the sensor coating after the interaction took too long.

Conservative management of MRI-confirmed knee osteoarthritis with instrument-assisted soft-tissue mobilization, joint manipulation, and platelet-rich plasma.

Objective: To describe the successful conservative management of a patient with chronic degenerative knee pain.

Clinical Features: An active 47 year-old female office-worker with intermittent right knee pain inferolateral to the right patella for eight months described difficulty ascending stairs, sitting on a chair for one hour, and squatting. A physical exam led to the diagnosis of a suspected chronic degenerative tear of the posterior horn of the right medial meniscus and chronic right subpatellar chondrosis, in addition to extensive cartilaginous degeneration revealed by an MRI study conducted prior to initial presentation.
