AI Article Synopsis
- The study examines the effect of MR neurography (MRN) on diagnosing and managing patients with suspected brachial plexopathy over 18 months.
- Out of 121 patients, MRN changed the clinical diagnosis for 75.2%, with 47.1% showing mild changes and 28% substantial changes; it influenced 15.7% of patients to undergo different therapies.
- The findings suggest that MRN is crucial for clinical decision-making in suspected brachial plexopathy and provides important information that often aligns with electrodiagnostic tests.
Article Abstract
Objective: To study the impact of brachial plexus MR neurography (MRN) in the diagnostic thinking and therapeutic management of patients with suspected plexopathy.
Methods: MRN examinations of adult brachial plexuses over a period of 18 months were reviewed. Relevant data collection included-patient demographics, clinical history, pre-imaging diagnostic impression, pre-imaging treatment plan, post-imaging diagnosis, post-imaging treatment plan, surgical notes and electrodiagnostic (ED) results. Impact of imaging on the pre-imaging clinical diagnosis and therapeutic management were classified as no change, mild change or substantial change.
Results: Final sample included 121 studies. The common aetiologies included inflammatory in 31 (25.6%) of 121 patients, trauma in 29 (23.9%) of 121 patients and neoplastic in 26 (21.5%) of 121 patients. ED tests were performed in 47 (38.8%) of 121 patients and these showed concordance with MRN findings in 31 (66.0%) of 47 patients. Following MRN, there was change in the pre-imaging clinical impression for 91 (75.2%) of 121 subjects, with a mild change in diagnosis in 57 (47.1%) of 121 patients and a substantial change in 34 (28.0%) of 121 patients. 19 (15.7%) of 121 patients proceeded to therapies that would not have been performed in the same manner without the information obtained from MRN.
Conclusion: MRN of the brachial plexus significantly impacts clinical decision-making and should be routinely performed in suspected brachial plexopathy. Advances in knowledge: MRN significantly impacts the diagnostic thinking and therapeutic management of patients with suspected brachial plexopathy. MRN not only provides concordant information to ED tests in majority of cases, but also supplements with additional diagnostic data in patients who are ED negative.

Background: Prompt primary percutaneous coronary intervention (pPCI) is crucial for the prognosis and reduction of myocardial damage in ST-segment elevation myocardial infarction (STEMI) patients. The Coronavirus Disease 2019 (COVID-19) pandemic had multifaceted impacts on healthcare. This study assessed the effects of the pandemic on pPCI procedures and clinical outcomes in emergency STEMI patients.

Introduction: It is reasonable to assume that lumbar spinal stenosis (LSS) affects the cauda nerve roots also at night.
Research Question: Does microsurgical decompression influence sleep quality and position?
Materials And Methods: A study nurse interviewed 140 patients scheduled for LSS decompression using the Pittsburgh Sleep Quality Index (PSQI), Spinal Stenosis Measure (SSM), Numeric Rating Scale (NRS) for back and leg pain, Douleur Neuropathique (DN4), and Charlson Comorbidity Index. Epidemiologic and MRI data were collected along with self-reported rankings of preferred sleep positions (prone, supine, side, and fetal).

Backgrounds: Recent research suggests that uric acid, as a metabolite with antioxidant properties, may affect muscle function and health. However, the association between serum uric acid (SUA) and low muscle mass remains relatively obscure. This study focuses on the association between SUA and low muscle mass in a middle-aged and elderly population in the United States.

Objectives: Systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) are more common in women, partly due to differences in female sex hormones. Menopausal hormone therapy (MHT) is widely used to alleviate climacteric symptoms. Here, the relationship between MHT and SLE/SSc was investigated in a nested case-control study.
