Objective: To evaluate the significance of umbilical cord chitotriosidase concentrations in pregnancies with mild preeclampsia and explore the relationship between fetal chitotriosidase levels and fetal blood flow velocity.
Method: The study population included control group (n=40) and study group with mild preeclampsia (n=40). Umbilical cord blood samples were collected immediately after delivery. Umbilical artery (UA) flow velocity waveform was determined just before delivery.
Results: Umbilical cord chitotriosidase levels and UA S/D rate were significantly high in preeclamptic group.
Conclusion: Chitotriosidase may be useful biochemical marker of fetal compromise that reflects the severity of fetoplacental blood flow resistance in pregnancies complicated by preeclampsia.

The European Commission authorized the use of dried yellow mealworm (Tenebrio molitor - TM) as a food ingredient under Regulation EU 2021/882. As TM emerges as an important allergen source, sensitization and allergy to TM in various populations need investigation. The aim of this study was to assess the incidence of sensitization to TM before its introduction as a food ingredient in Poland, as well as checking the occurrence of co-sensitivity to TM and other invertebrate allergenic extracts and molecules.

Method: As genetic and environmental factors interactively impact these conditions, we investigated how risk factors such as APOE genotype, age, and sex influence immune activation markers and AD biomarkers in cerebrospinal fluid (CSF) in elderly individuals enrolled in the Mayo Clinic Study of Aging cohort. Among cognitively unimpaired individuals aged over 65 at the baseline visit (N=298), we measured 365 CSF immune activation markers using the proximity extension assay.
Background: Increasing evidence supports the use of plasma biomarkers of amyloid, tau, neurodegeneration and neuroinflammation for diagnosis of dementia. However, their performance for positive and differential diagnosis of dementia with Lewy bodies (DLB) in clinical settings is still uncertain.
Method: We conducted a retrospective biomarker study in two tertiary memory centers, Paris Lariboisière and CM2RR Strasbourg, France, enrolling patients with DLB (n=104), Alzheimer's disease (AD, n=76) and neurological controls (NC, n=27).

Background: Emerging evidence underscores the importance of neuroinflammation in the progression of Alzheimer's disease (AD) pathophysiology. Recent studies indicate the involvement of the inflammatory mechanisms both in amyloid- β (Aβ) and tau deposition in the brain. Nevertheless, due to the complexity of the immune responses and the intricate interplay between the peripheral and the central nervous systems, identifying biomarkers that reflect the brain´s inflammatory state in AD has been a challenge.
