Long-term lithium treatment decreases kidney function. However, it remains unclear whether stopping lithium improves kidney function. ⋯ Stopping lithium slowed down mean eGFR decline. This effect was more pronounced in participants with lower eGFR at the time of lithium discontinuation. In participants who restarted lithium, the annual decline of eGFR reverted to pre-lithium discontinuation levels.

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.
