Introduction: Despite unprecedented pressures on urgent and emergency care services, there is no clear consensus on how to provide acute medical care delivery in the UK. These pressures can lead to significant delays in care for patients presenting with emergencies when admitted via traditional routes through the emergency department. Historically, a separate pathway has existed where patients are directly admitted to acute medicine services without attending the emergency department. It is suspected that there is a significant variation in how these patients are selected, triaged and managed in the UK. This systematic review will assess the methods and evidence base used for direct patient admissions to acute medicine services compared with traditional admission pathways through the emergency department.

Methods And Analysis: A systematic review of the literature will be conducted and a total of six databases will be searched: MEDLINE (Ovid), The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE in process, Web of Science, CINAHL and Embase. This will include studies from the period 01 January 1975 to 24 January 2024. Covidence software will be the platform for the extraction of data and paper screening with the selection process reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram. Both title and abstract screening and full-text screening will be done by two reviewers independently. The risk of bias of included studies will be assessed using the methods introduced in the Cochrane Handbook for Systematic Reviews of Interventions and the tool used will be dependent on the type of study. Where possible, outcomes will be dealt with as continuous variables. Change percentage will be assessed between any pathway characteristic or outcome. The ² test and ² test will be used to evaluate the heterogeneity of included studies. Where appropriate, relevant meta-analysis techniques will be used to compare studies and forest plot produced.

Ethics And Dissemination: This systematic review does not require ethical approval. Findings will be disseminated widely in peer-reviewed publication and media, including conferences.

Prospero Registration Number: CRD42023495786.

Safety and efficacy of tirofiban in the endovascular treatment of intracranial aneurysms: a systematic evaluation and meta-analysis.

Neurosurg Rev

January 2025

Hengyang Key Laboratory of Hemorrhagic Cerebrovascular Disease, Department of Neurosurgery, the Second Affiliated Hospital, Hengyang Medical School, University of South China, Hengyang, 421000, Hunan, China.

Patients with intracranial aneurysms (IA) undergoing endovascular treatment face varying risks and benefits when tirofiban is used for thromboprophylaxis during surgery. Currently, there is a lack of high-level evidence summarizing this information. This study aims to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of tirofiban during endovascular treatment of IA.

Magnetic resonance imaging (MRI) is frequently used to monitor disease progression in multiple sclerosis (MS). This study aims to systematically evaluate the correlation between MRI measures and histopathological changes, including demyelination, axonal loss, and gliosis, in the central nervous system of MS patients. We systematically reviewed post-mortem histological studies evaluating myelin density, axonal loss, and gliosis using quantitative imaging in MS.

Systematic Review of Hybrid Vision Transformer Architectures for Radiological Image Analysis.

J Imaging Inform Med

January 2025

School of Computing, Informatics, and Decision Systems Engineering, Arizona State University, Tempe, AZ, USA.

Vision transformer (ViT)and convolutional neural networks (CNNs) each possess distinct strengths in medical imaging: ViT excels in capturing long-range dependencies through self-attention, while CNNs are adept at extracting local features via spatial convolution filters. While ViT may struggle with capturing detailed local spatial information, critical for tasks like anomaly detection in medical imaging, shallow CNNs often fail to effectively abstract global context. This study aims to explore and evaluate hybrid architectures that integrate ViT and CNN to leverage their complementary strengths for enhanced performance in medical vision tasks, such as segmentation, classification, reconstruction, and prediction.

Considering the potential detrimental impact of poverty on psychological development and the resulting harmful cycles, implementing poverty alleviation interventions is necessary for children and adolescents. Although several meta-analyses have demonstrated the effectiveness of monetary poverty reduction programs, there remains a significant gap in understanding how multidimensional poverty reduction strategies boost psychological development. This meta-analysis aims to address this gap by disclosing the impact of multifaceted anti-poverty interventions on the psychological development of children and adolescents.
