"Placing community in the driver's seat": Key strategies and critical enablers of an equitable place-based COVID-19 vaccination response.

Addressing health inequities requires both national and local-level action. In the case of COVID-19, locally-led place-based programs were instrumental in addressing vaccination inequities that resulted from implementation gaps in national and state-level universal COVID-19 vaccination programs. To prepare for future pandemics, understanding which local strategies are effective and the conditions that enable their effectiveness is crucial.

The pathogenicity of PSEN2 variants is tied to Aβ production and homology to PSEN1.

Introduction: Though recognized as a potential cause of autosomal dominant Alzheimer's disease, the pathogenicity of many PSEN2 variants remains uncertain. We compared amyloid beta (Aβ) production across all missense PSEN2 variants in the AlzForum database and, when possible, to corresponding PSEN1 variants.

Methods: We expressed 74 PSEN2 variants, 21 of which had known, homologous PSEN1 pathogenic variants with the same amino acid substitution, in HEK293 cells lacking presenilin 1/2.

Comparative neurofilament light chain trajectories in CSF and plasma in autosomal dominant Alzheimer's disease.

Disease-modifying therapies for Alzheimer's disease (AD) are likely to be most beneficial when initiated in the presymptomatic phase. To track the benefit of such interventions, fluid biomarkers are of great importance, with neurofilament light chain protein (NfL) showing promise for monitoring neurodegeneration and predicting cognitive outcomes. Here, we update and complement previous findings from the Dominantly Inherited Alzheimer Network Observational Study by using matched cross-sectional and longitudinal cerebrospinal fluid (CSF) and plasma samples from 567 individuals, allowing timely comparative analyses of CSF and blood trajectories across the entire disease spectrum.

Heterogeneity in 10-year course trajectories of moderate to severe major depressive disorder among veterans.

Aims: Epidemiological studies show that despite the episodic nature, the long-term trajectory of depression can be variable. This study evaluated the heterogeneity of 10-year trajectory of major depressive disorder (MDD) related service utilization and associated clinical characteristics among US Veterans with a first diagnosis after 9/11.

Methods: Using a cohort design, electronic health record data for 293,265 Operation Enduring Freedom and Iraqi Freedom (OEF/OIF) Veterans were extracted to identify those with MDD between 2001 and 2021 with a full preceding year of clinical data and 10 years following the diagnosis.
