Proteomic signatures of Alzheimer's disease and Lewy body dementias: A comparative analysis.

Introduction: We aimed to identify unique proteomic signatures of Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and Parkinson's disease dementia (PDD).

Methods: We conducted a comparative proteomic analysis of 33 post mortem brains from AD, DLB, and PDD individuals without dementia focusing on prefrontal, cingulate, and parietal cortices, using weighted gene co-expression network analyses with differential enrichment analysis.

Results: Network modules revealed hub proteins common to all dementias.

The SLaM Brain Health Clinic: remote biomarker enhanced memory clinic for people with mild cognitive impairment within a National Health Service mental health trust.

Background: The novel South London and Maudsley Brain Health Clinic (SLaM BHC) leverages advances in remote consultations and biomarkers to provide a timely, cost-efficient and accurate diagnosis in mild cognitive impairment (MCI).

Aims: To describe the organisation, patient cohort and acceptability of the remote diagnostic and interventional procedures.

Method: We describe the recruitment, consultation set-up, the clinical and biomarker programme, and the two online group interventions for cognitive wellbeing and lifestyle change.

Telomere length and cognitive changes in 7,877 older UK adults of European ancestry.

Background: Telomere length (TL) has been linked to cognitive function, decline and dementia. This study aimed to explore whether both measured TL and genetic disposition for TL predict dimensions of cognitive performance in a longitudinal sample of older UK adults.

Methods: We analysed data from PROTECT study participants aged ≥50 years without a dementia diagnosis, who had completed longitudinal cognitive testing.

Functional and connectivity correlates associated with Parkinson's disease psychosis: a systematic review.

Neural underpinnings of Parkinson's disease psychosis remain unclear to this day with relatively few studies and reviews available. Using a systematic review approach, here, we aimed to qualitatively synthesize evidence from studies investigating Parkinson's psychosis-specific alterations in brain structure, function or chemistry using different neuroimaging modalities. PubMed, Web of Science and Embase databases were searched for functional MRI (task-based and resting state), diffusion tensor imaging, PET and single-photon emission computed tomography studies comparing Parkinson's disease psychosis patients with Parkinson's patients without psychosis.

Documenting human papillomavirus vaccine refusal among adolescents in electronic health records: A mixed methods study.

Background: Human papillomavirus (HPV) vaccination is often refused by patients or caregivers. We conducted a mixed-methods study to understand how health care providers document HPV vaccination refusal and use this information in subsequent encounters.

Methods: Using electronic health records (EHR) in a public academic health system, we identified patients aged 9-17 years with documentation of refusal of a recommended vaccination in billing codes or clinic notes from October 15, 2015 and December 31, 2021.
