The Cannabinoid Use in Progressive Inflammatory brain Disease (CUPID) trial: a randomised double-blind placebo-controlled parallel-group multicentre trial and economic evaluation of cannabinoids to slow progression in multiple sclerosis.
The Cannabinoid Use in Progressive Inflammatory brain Disease (CUPID) trial aimed to determine whether or not oral Δ(9)-tetrahydrocannabinol (Δ(9)-THC) slowed the course of progressive multiple sclerosis (MS); evaluate safety of cannabinoid administration; and, improve methods for testing treatments in progressive MS. ⋯ The CUPID trial failed to demonstrate a significant treatment effect in primary or secondary outcomes. There were no major safety concerns, but unwanted side effects seemed to affect compliance. Participants were more disabled than in previous studies and deteriorated less than expected, possibly reducing our ability to detect treatment effects. RMT analyses supported performance of MS-specific rating scales as measures, enabled group- and individual person-level examination of treatment effects, but did not influence study inferences. The intervention had significant additional costs with no improvement in health outcomes; therefore, it was dominated by usual care and not cost-effective. Future work should focus on determining further factors to predict clinical deterioration, to inform the development of new studies, and modifying treatments in order to minimise side effects and improve study compliance. The absence of disease-modifying treatments in progressive MS warrants further studies of the cannabinoid pathway in potential neuroprotection.

ReviewA systematic review and economic evaluation of intraoperative tests [RD-100i one-step nucleic acid amplification (OSNA) system and Metasin test] for detecting sentinel lymph node metastases in breast cancer.
In breast cancer patients, sentinel lymph node biopsy is carried out at the same time as the removal of the primary tumour to postoperatively test with histopathology for regional metastases in the sentinel lymph node. Those patients with positive test results are then operated on 2-4 weeks after primary surgery to remove the lymph nodes from the axilla (axillary lymph node dissection, ALND). New molecular tests RD-100i [one-step nucleic acid amplification (OSNA); based on messenger RNA amplification to identify the cytokeratin-19 (CK19) gene marker] (Sysmex, Norderstedt, Germany) and Metasin (using the CK19 and mammaglobin gene markers) (Cellular Pathology, Princess Alexandra Hospital NHS Trust, Harlow, UK) are intended to provide an intraoperative diagnosis, thereby avoiding the need for postoperative histopathology and, in positive cases, a second operation for ALND. ⋯ The National Institute for Health Research Health Technology Assessment programme.

ReviewTotal hip replacement and surface replacement for the treatment of pain and disability resulting from end-stage arthritis of the hip (review of technology appraisal guidance 2 and 44): systematic review and economic evaluation.
Total hip replacement (THR) involves the replacement of a damaged hip joint with an artificial hip prosthesis. Resurfacing arthroplasty (RS) involves replacement of the joint surface of the femoral head with a metal surface covering. ⋯ The National Institute for Health Research Health Technology Assessment programme.

ReviewWhat is the clinical effectiveness and cost-effectiveness of conservative interventions for tendinopathy? An overview of systematic reviews of clinical effectiveness and systematic review of economic evaluations.
Lateral elbow tendinopathy (LET) is a common complaint causing characteristic pain in the lateral elbow and upper forearm, and tenderness of the forearm extensor muscles. It is thought to be an overuse injury and can have a major impact on the patient's social and professional life. The condition is challenging to treat and prone to recurrent episodes. The average duration of a typical episode ranges from 6 to 24 months, with most (89%) reporting recovery by 1 year. ⋯ The National Institute for Health Research Health Technology Assessment programme.

ReviewScreening for psychological and mental health difficulties in young people who offend: a systematic review and decision model.
There is policy interest in the screening and treatment of mental health problems in young people who offend, but the value of such screening is not yet known. ⋯ The National Institute for Health Research Health Technology Assessment programme.
