Diffusion weighted imaging to predict longer term response in Crohn's disease patients commencing biological therapy: Results from the MOTILITY Trial.

Objectives: Predicting longer term response to biological therapy for small bowel Crohn's disease (SBCD) is an unmet clinical need. Diffusion-weighted MR imaging (DWI) may indicate disease activity, but its predictive ability, if any, is unknown. We investigated the prognostic value of DWI for one year response or remission (RoR) in SBCD patients commencing biologic therapy, including incremental value over C-reactive protein (CRP) and faecal calprotectin (FC).

Assessing post-operative dietary intake in older adult hip fracture patients: An observational study protocol.

Fragility fractures of the hip are a common injury in England. Meeting post-operative resting energy expenditure (REE) needs are fundamental to recovery from trauma that with greater nutritional intake, post-operative complications and length of stay can be reduced. However, dietary intake can be overlooked when the goal is prompt surgery to reduce pain and lower the risks of mortality at 30 days and 1 year.

Ultrasound and blind endometrial sampling for detection of endometrial cancer in women with postmenopausal bleeding.

This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows: To assess the diagnostic accuracy of endometrial sampling with histology in the diagnosis of endometrial cancer in women with postmenopausal bleeding and thickened endometrium on ultrasound. Diagnosis will be verified by the reference standards, hysteroscopy with histology, obtained by targeted (such as grasp biopsy of the endometrium or resection of focal pathology) or global sampling (with dilation and curettage), and histology of hysterectomy specimens.

Diagnostic accuracy of prehospital ultrasound in detecting lung injury in patients with trauma: a systematic review and meta-analysis.

Background: Ultrasound is now readily available in the prehospital setting and its use has been highlighted as one of the top research priorities in prehospital care. Clinical examination remains the standard care for diagnosing lung injury in the prehospital setting, yet this can be challenging and has poor diagnostic accuracy. This review evaluates the accuracy of prehospital ultrasound for the diagnoses of pneumothorax, haemothorax and pulmonary contusions in patients with trauma.

An analysis of availability and implications of unlabeled retracted articles on Sci-Hub.

Background: Researchers are increasingly accessing scientific articles through unauthorized websites like Sci-Hub. Sci-Hub contains retracted articles, including those which are not labelled as retracted, and this is a potential threat to academic research.

Methods: This study analyses the extent of the availability of retracted articles within the Sci-Hub, particularly focusing on the presence of unlabeled retracted articles (URA) which may inadvertently be used in subsequent research, thus propagating flawed findings.
