Objectives: To determine the prevalence of acromioclavicular (AC) joint and subacromial space imaging abnormalities in asymptomatic adults, with a secondary objective of comparing findings between asymptomatic and symptomatic shoulders within the same study populations.

Methods: We conducted a systematic review of studies examining shoulder imaging abnormalities detected by X-ray, ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) in asymptomatic adults (PROSPERO registration CRD42018090041). This report focuses on AC joint and subacromial space abnormalities.

Globally, prostate cancer is the second most common malignancy in males, with over 400 thousand men dying from the disease each year. A common treatment modality for localized prostate cancer is radiotherapy. However, up to half of high-risk patients can relapse with radiorecurrent prostate cancer, the aggressive clinical progression of which remains severely understudied.

Article Synopsis
  • The study aimed to investigate imaging biomarkers for tumor response in patients with intermediate/high-grade soft tissue sarcomas (STS) following neoadjuvant radiotherapy (nRT), focusing on changes in imaging and pathology.
  • The analysis involved 107 patients, measuring tumor characteristics like diameter, volume, and signal intensity before and after treatment, and correlated these with pathological outcomes such as necrosis and viable cell percentage using statistical methods.
  • Results showed a low rate of complete tumor response, with specific subtypes like myxoid liposarcoma and undifferentiated pleomorphic sarcoma exhibiting significant changes in tumor size and signal intensity related to necrosis and fibrosis post-radiotherapy.

Background: Immunometabolism is a crucial determinant of immune cell function, influencing cellular activation and differentiation through metabolic pathways. The intricate interplay between metabolism and immune responses is highlighted by the distinct metabolic programs utilized by immune cells to support their functions. Of particular interest is the pentose phosphate pathway (PPP), a key metabolic pathway branching out of glycolysis that plays a pivotal role in generating NADPH and pentose sugars crucial for antioxidant defense and biosynthesis.
