Epidemiological studies have shown that vitamin or trace-element deficiencies are frequent in the general population. Food intake can be incriminated, but various drugs may also precipitate micronutrient deficits. Indeed, the consequences of pharmacotherapy on micronutrients are yet modestly explored in clinical practice settings. We aim at sensitizing physicians on the impact of frequently used drugs on vitamins and trace-elements. High risk populations for micronutrient deficiencies and indications for substitution are discussed.

Background: Availability of amyloid modifying therapies will dramatically increase the need for disclosure of Alzheimer's disease (AD) related genetic and/or biomarker test results. The 21st Century Cares Act requires the immediate return of most medical test results, including AD biomarkers. A shortage of genetic counselors and dementia specialists already exists, thus driving the need for scalable methods to responsibly communicate test results.

In two clinical studies (phase 2, NCT01767311 and phase 3 ClarityAD, NCT03887455) in early Alzheimer's disease, lecanemab substantially reduced amyloid PET and significantly slowed clinical decline on multiple measures of cognition and function, including CDR-SB at 18 months. Models describing the change in amyloid PET and CDR-SB in response to lecanemab treatment were used to explore the impact of changing from the initial dosage regimen (10 mg/kg every 2 weeks [Q2W]) to a less intensive maintenance dosing regimen (10 mg/kg every 4 weeks [Q4W]) on clinical efficacy, and to explore the optimal duration of the initial dosing regimen.

Background: Dysregulated GABA/somatostatin (SST) signaling has been implicated in psychiatric and neurodegenerative disorders. The inhibition of excitatory neurons by SST+ interneurons, particularly through α5-containing GABAA receptors (α5-GABAAR), plays a crucial role in mitigating cognitive functions. Previous research demonstrated that an α5-positive allosteric modulator (α5-PAM) mitigates working memory deficits and reverses neuronal atrophy in aged mice.

Low-recruiting sites represent a large financial and operational burden and may negatively impact trial success either by selecting inappropriate participants and/or high prevalence of data quality issues. We previously reported that >60% of sites in schizophrenia clinical trials recruited ≤5 participants.
View Article and Find Full Text PDFBackground: Identifying strategies to engage with potential participants is critical for efficient enrollment in Alzheimer's Disease (AD) trials. Previous studies link faster speed of first contact with successful phone interview completion for Major Depressive Disorder (MDD) participants. This has not been examined in AD participants.
