Background: Population-based cohort studies play a crucial role in unraveling the underlying causes of dementia among older individuals. While previous research has indicated an increase in limbic-predominant age-related TDP-43 encephalopathy neuropathological change (LATE-NC) with age, only limited investigations have delved into this phenomenon within a population-based context. In this study, we examined the prevalence of LATE-NC and its correlations with other brain pathologies and cognitive function in individuals aged > 85 years.

Desmoid tumour: a rare cause of congenital unilateral calf enlargement mimicking calf hypertrophy.

Desmoid tumours, also known as aggressive fibromatosis, are rare tumours derived from mesenchymal stem cells, accounting for only 0.03 % of all tumours. While 85-90 % of cases are sporadic, desmoid tumours can occasionally be associated with Gardner syndrome (or Familial Adenomatous Polyposis), which is linked to variants in the tumour suppressor gene, APC (adenomatous polyposis coli) gene on chromosome 5.

Limbic-predominant age-related TDP-43 encephalopathy in the oldest old: a population-based study.

Population-based cohort studies are essential for understanding the pathological basis of dementia in older populations. Previous studies have shown that limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) increases with age, but there have been only a few studies, which have investigated this entity in a population-based setting. Here we studied the frequency of LATE-NC and its associations with other brain pathologies and cognition in a population aged ≥ 85 years.

Glycosylation spectral signatures for glioma grade discrimination using Raman spectroscopy.

Background: Gliomas are the most common brain tumours with the high-grade glioblastoma representing the most aggressive and lethal form. Currently, there is a lack of specific glioma biomarkers that would aid tumour subtyping and minimally invasive early diagnosis. Aberrant glycosylation is an important post-translational modification in cancer and is implicated in glioma progression.

Distribution of Lewy-related pathology in the brain, spinal cord, and periphery: the population-based Vantaa 85 + study.

Evolving evidence has supported the existence of two anatomically distinct Lewy-related pathology (LRP) types. Investigation of spinal cord and peripheral LRP can elucidate mechanisms of Lewy body disorders and origins of synuclein accumulation. Still, very few unselected studies have focused on LRP in these regions.
