Background: Subjective cognitive complaints (SCC) have been mostly studied in the context of Alzheimer's disease in memory clinic settings. The potential of combining SCC with genetic information and blood biomarkers of neurodegenerative diseases for risk assessment of dementia and depression in the absence of dementia among community-dwelling older adults has so far not been explored.

Methods: Data were based on a population-based cohort of 6357 participants with a 17-year follow-up (ESTHER study) and a clinic-based cohort of 422 patients.

β-amyloid (Aβ) and tau aggregation as well as neuronal injury and atrophy (ATN) are the major hallmarks of Alzheimer's disease (AD), and biomarkers for these hallmarks have been linked to neuroinflammation. However, the detailed regional associations of these biomarkers with microglial activation in individual patients remain to be elucidated. We investigated a cohort of 55 patients with AD and primary tauopathies and 10 healthy controls that underwent TSPO-, Aβ-, tau-, and perfusion-surrogate-PET, as well as structural MRI.

Article Synopsis
  • Alzheimer's disease (AD) affects brain connectivity, but how lifelong experiences (cognitive reserve or CR) relate to this is not well-understood.
  • A study analyzed brain scans of 228 participants, including healthy individuals and those at various AD stages, focusing on the default-mode network's connectivity.
  • Results showed that higher lifetime experiences scores were linked to better connectivity in the brain's default-mode network, suggesting that engaging in various activities may help preserve cognitive function even as memory declines.

Article Synopsis
  • - The study investigates how microglial activation, which is linked to neuroinflammation in Alzheimer's disease (AD), relates to the connectivity of brain regions in Aβ-positive early AD patients compared to healthy controls.
  • - Utilizing advanced imaging techniques like positron emission tomography (PET) and magnetic resonance imaging (MRI), researchers found that microglial activation was more prominent in functionally connected brain areas in AD patients, correlating with cognitive decline.
  • - The findings suggest that, similar to tau pathology, microglial activation spreads along highly interconnected brain pathways, highlighting its potential role in the progression of neurodegeneration in AD.

Article Synopsis
  • The study investigates the link between inflammation and late-onset depression (LOD) as well as cognitive decline, finding specific inflammatory biomarkers associated with LOD but not with recurrent depression.
  • Researchers analyzed data from a long-term cohort study of older adults, focusing on 1,665 participants to measure various inflammatory biomarkers at baseline.
  • Key findings reveal that increased levels of interleukin 10 (IL-10) and C-C chemokine ligand 4 (CCL4) are significantly associated with higher risks of LOD and vascular dementia, suggesting a potential shared biological mechanism.

Article Synopsis
  • An outbreak of VIM-1-producing Klebsiella pneumoniae in Spain posed a significant threat to hospitals, prompting a detailed genomic study of 18 isolates between 2005 and 2007.
  • The majority of isolates were clonal (17 ST39), while one acquired a plasmid responsible for antibiotic resistance, exhibiting nearly universal resistance to antibiotics.
  • Although no evidence of widespread distribution of this strain was found, the VIM-1 plasmid was present in various Enterobacterales species, indicating localized concerns about antibiotic resistance evolution.

Cathepsin(Cat)-S processing of the invariant chain-MHC-II complex inside antigen presenting cells is a central pathomechanism of autoimmune-diseases. Additionally, Cat-S is released by activated-myeloid cells and was recently described to activate protease-activated-receptor-(PAR)-2 in extracellular compartments. We hypothesized that Cat-S blockade targets both mechanisms and elicits synergistic therapeutic effects on autoimmune tissue injury.
