Background: Magnetic resonance imaging localises cancer in the prostate, allowing for a targeted biopsy with or without transrectal ultrasound-guided systematic biopsy. Targeted biopsy methods include cognitive fusion, where prostate lesions suspicious on magnetic resonance imaging are targeted visually during live ultrasound, and software fusion, where computer software overlays the magnetic resonance imaging image onto the ultrasound in real time. The effectiveness and cost-effectiveness of software fusion technologies compared with cognitive fusion biopsy are uncertain.

Article Synopsis
  • The study evaluated the safety and effectiveness of statins, ezetimibe, and their combination for treating children with heterozygous familial hypercholesterolaemia (HeFH), using systematic reviews and various meta-analyses from RCTs.* -
  • Results showed that all lipid-lowering therapies (LLTs) were effective in reducing cholesterol levels, with statins leading to significant reductions in low-density lipoprotein cholesterol (LDL-C), especially when combined with ezetimibe.* -
  • While no safety or tolerability issues were identified, the extent of LDL-C reduction varied by treatment dosage and type, highlighting the need for more research on long-term safety and effectiveness.*

Article Synopsis
  • * A systematic search identified nine relevant studies, mostly using randomized controlled trials to analyze costs and effects; however, many studies failed to specify the decision-making context or target decision makers effectively.
  • * The review highlights limitations in the ability of existing studies to guide funders in understanding the full value of self-help group interventions, suggesting that a cross-sectoral approach to presenting evidence could enhance decision-making.

Introduction: Lower limb conditions requiring reconstructive surgery can be either congenital or acquired from trauma, infection or other medical conditions. Patient-reported outcome measures (PROMs) are often used by healthcare professionals to assess the impact of a patient's condition (and treatment) on quality of life. However, we are not aware of any measures developed specifically for people requiring lower limb reconstructive surgery.

Background: Patients with low estimated glomerular filtration rates may be at higher risk of post-contrast acute kidney injury following contrast-enhanced computed tomography imaging. Point-of-care devices allow rapid measurement of estimated glomerular filtration rates for patients referred without a recent estimated glomerular filtration rate result.

Objectives: To assess the clinical effectiveness and cost-effectiveness of point-of-care creatinine tests for outpatients without a recent estimated glomerular filtration rate measurement who need contrast-enhanced computed tomography imaging.

Article Synopsis
  • - This article explores the challenges of systematic reviews for medical devices, particularly in assessing selective internal radiation therapy devices for treating liver cancer, to assist the National Institute for Health and Care Excellence in their technology appraisal.
  • - Researchers conducted an extensive search across various medical databases and grey literature sources, leading to the selection of 64 eligible studies from an initial pool of 4,755 records, focusing on three specific devices.
  • - The analysis highlighted that only two out of the 20 critically appraised studies had a low risk of bias, leading to a cautious conclusion about the overall reliability of the evidence, as many studies were small and yielded inconsistent results.

Background: Regular off-treatment imaging is often used to assess for recurrence of disease after childhood cancer treatment. It is unclear if this increases survival, or what burden surveillance places on patients, families, or health-care services. This systematic review examines the impact of routine surveillance imaging after treatment of pediatric extracranial solid tumors.

Background: This systemic review aims to synthesise the current literature surrounding off-therapy surveillance imaging in children and young people with extra-cranial solid tumours, with a view to establishing if routine imaging studies after treatment for childhood cancer increase overall survival, increase the psychological distress caused to patients and families, result in other harms to patients and are cost-effective strategies. Within this manuscript, we also describe how patient and public involvement has impacted upon the protocol.

Methods: The search will cover thirteen different databases, key conference proceedings and trial registers, as well as reference lists and forward citations of included papers.

Article Synopsis
  • Many existing treatments for phantom limb pain (PLP) lack strong evidence and clear management guidelines, prompting a need for systematic reviews of neurostimulation therapies.
  • The study aimed to evaluate various brain and spinal stimulation therapies' effectiveness for chronic PLP, considering both invasive (like deep brain and spinal cord stimulation) and non-invasive methods (like rTMS and tDCS).
  • Findings indicated that while rTMS showed promise for short-term PLP relief, better evidence for invasive therapies is necessary, as no RCTs were found for them.
