Machine learning models to predict surgical case duration compared to current industry standards: scoping review.

Background: Surgical waiting lists have risen dramatically across the UK as a result of the COVID-19 pandemic. The effective use of operating theatres by optimal scheduling could help mitigate this, but this requires accurate case duration predictions. Current standards for predicting the duration of surgery are inaccurate.

Patellar resurfacing and kneeling ability after total knee arthroplasty: a systematic review.

Background: Difficulty kneeling following total knee arthroplasty (TKA) remains highly prevalent, and has cultural, social, and occupational implications. With no clear evidence of superiority, whether or not to resurface the patella remains debatable. This systematic review examined whether resurfacing the patella (PR) or not (NPR) influences kneeling ability following TKA.

A Simple Technique to Remove an Incarcerated Ceramic Liner in Revision Hip Arthroplasty.

Extraction of a well-fixed ceramic liner during revision total hip arthroplasty can be technically challenging, particularly when acetabular fixation screws prevent en bloc removal of the shell and insert without causing collateral damage to the adjacent pelvic bone. It is also important to remove the ceramic liner intact, as ceramic debris left in the joint may cause third body wear with premature articular wear of the revised implants. We describe a novel technique to extract an incarcerated ceramic liner when previously described strategies prove ineffective.

Right atrial and SVC infiltrating mass-the entity of infiltrating lipoma.

Background: Cardiac lipomas are rare benign primary cardiac tumours primarily composed of mature adipocytes. They are usually well defined, encapsulated masses, but rarely demonstrate malignant characteristics by infiltrating the myocardium. This causes diagnostic uncertainty as it becomes a priority to rule out primary malignant cardiac tumours such as sarcoma which often carry a poor prognosis.

The utility of drug reaction assessment trials for inhaled therapies in patients with chronic lung diseases.

Background: Current guidelines recommend a Drug Reaction Assessment (DRA) before beginning inhaled therapies to assess for bronchoconstriction and tolerability. There is limited evidence to support this recommendation.

Methods: In this study we aimed to establish the predictors of successful DRAs in different patient groups using a cohort of all DRAs performed in adults between 2011 and 2016 at the Royal Brompton Hospital.
