Background: Classical literature has pointed at lateralization of the relationship between memory scores and cerebral hemisphere injury. Epilepsy studies have suggested an association between left hippocampal damage and verbal memory deficits, and between right hippocampal damage and visual memory deficits. We aimed to explore this concept in the context of tauopathy due to Alzheimer's disease.

Its disease mechanisms are multifactorial but has centered mostly on endothelial dysfunction and smooth muscle hyperreactivity. To facilitate the investigation of these mechanisms in cell culture, we generated and characterized three induced pluripotent stem cell (iPSC) lines from patients with CAV.

Based on in vitro data, the oxidative hepatic metabolism of zongertinib is principally driven by cytochrome P450 (CYP) 3A4/5. Therefore, zongertinib may be affected by strong CYP3A inducers, like carbamazepine.

Methods: We performed a retrospective analysis of individuals with early-onset (age <65 years at onset) and/or atypical dementia (features other than memory at onset), who were evaluated at a tertiary care memory clinic. All participants underwent measurements of CSF biomarkers (Aβ42, p-tau181, and total tau levels), as well as [F]FDG-PET scans, amyloid-PET scans, and plasma p-tau217 quantifications.
Article Synopsis
- The Affordable Care Act expanded Medicaid for children, leading to differences in coverage between states that adopted the expansion and those that did not.
- A study analyzed data on pediatric cardiac surgeries from 2010 to 2019 to see if Medicaid expansion improved surgical outcomes like mortality, complications, and length of hospital stay.
- Results showed no significant improvement in surgical outcomes in states that expanded Medicaid, indicating that while overall surgery mortality declined, Medicaid expansion did not lead to better results compared to non-expansion states.
