Clinical 7 Tesla magnetic resonance imaging: Impact and patient value in neurological disorders.
Magnetic resonance imaging (MRI) is a cornerstone of non-invasive diagnostics and treatment monitoring, particularly for diseases of the central nervous system. Although 1.5- and 3 Tesla (T) field strengths remain the clinical standard, the advent of 7 T MRI represents a transformative step forward, offering superior spatial resolution, contrast, and sensitivity for visualizing neuroanatomy, metabolism, and function. Recent innovations, including parallel transmission and deep learning-based reconstruction, have resolved many prior technical challenges of 7 T MRI, enabling its routine clinical use. ⋯ The unparalleled ability of 7 T MRI to study neurological diseases ex vivo at ultra-high resolution is also explored, offering new opportunities to understand pathophysiology and identify novel treatment targets. Additionally, the review provides a clinical perspective on patient handling and safety considerations, addressing challenges and practicalities associated with clinical 7 T MRI. By bridging research and clinical practice, 7 T MRI has the potential to redefine neuroimaging and advance the understanding and management of complex neurological disorders.

This meta-analysis aimed to determine the incidence and overall risk of major adverse cardiovascular events (MACEs) related to immune checkpoint inhibitors (ICIs). ⋯ The risk of MACEs during ICI treatment in patients with cancer is more common than is currently recognized. ICI use is closely associated with an increased risk of MACEs. Patients at risk were older, male, and had a history of radiation therapy.

Research on Mesoamerican Nephropathy, chronic kidney disease of unknown cause and chronic kidney disease of nontraditional cause has been going on for more than 20 years. Thousands of manual workers, especially in agriculture, are affected. The disease has been reported in different countries and regions, not only from heat-stressed sugarcane cutters in Central America but also from other occupational groups with strenuous work in hot environments. ⋯ Associations between exposure and kidney damage are strong, consistent, and specific, occur after acute and chronic exposure, display dose-effect and dose-response relationships, are plausible, and coherent. Improving working conditions by providing hydration, rest, and shade to heat-stress-exposed workers is beneficial. Continued global warming will increase the number of people at risk for dangerous heat exposure and kidney disease.
