Article Synopsis
  • - White matter hyperintensities indicate damage in the brain's white matter, which can lead to brain shrinkage and is linked to dementia; a study of over 51,000 people found that larger volumes of these hyperintensities correspond to thinner brain cortex.
  • - Researchers identified 20 significant genetic loci related to white matter hyperintensities that affect genes involved in brain cell types known to support vascular health and neuronal function; some of these genes play roles in processes like axonal structure and transport within the brain.
  • - The genetic traits tied to white matter issues were linked to cardiovascular health, neurodegeneration markers, and poorer cognitive performance, with a polygenic risk score effectively predicting dementia risk in a separate large

Article Synopsis
  • The study focuses on identifying brain amyloid positivity in non-demented individuals, which is vital for early Alzheimer's disease diagnosis and treatment to start before symptoms appear.
  • Researchers developed predictive models using data from 853 participants, analyzing various factors like demographics, cognitive tests, and biomarkers related to Alzheimer's.
  • The best-performing model, which included blood biomarkers and ApoE status, achieved high accuracy rates (AUCs of 0.82 and 0.90) in predicting amyloid positivity, surpassing traditional models that relied only on demographic and cognitive data.

KLEPTOSE CRYSMEB methylated cyclodextrin derivative displays less methylated group substitution than randomly methylated cyclodextrin. It has demonstrated an impact on atherosclerosis and neurological diseases, linked in part to cholesterol complexation and immune response, however, its impact on inflammatory cascade pathways is not clear. Thus, the impact of KLEPTOSE CRYSMEB on various pharmacological targets was assessed using human umbilical vein endothelial cells under physiological and inflammatory conditions, followed by screening against twelve human primary cell-based systems designed to model complex human tissue and disease biology of the vasculature, skin, lung, and inflammatory tissues using the BioMAP Diversity PLUS panel.

Article Synopsis
  • Neurofilament light chain (NfL) levels serve as a key biomarker for neuro-axonal damage in neurodegenerative disorders, and understanding the genetics behind these levels can reveal important molecular mechanisms.
  • A meta-analysis of genome-wide association studies identified significant genetic loci associated with blood NfL levels in both European and African American populations, highlighting two key regions.
  • The study also indicated that a higher polygenic risk score for NfL correlates with increased levels of other neurodegenerative biomarkers and suggests lower kidney function may lead to elevated NfL levels in the blood.

Article Synopsis
  • Laparoscopic cornuectomy is commonly used to remove Essure® implants, but there's a risk of the device fragmenting, which can complicate surgery.
  • A study of 66 patients by gynecologists assessed the effectiveness of intraoperative radiographs compared to direct inspection of the removed implants to check for any remaining fragments.
  • Results showed that while the sensitivity and specificity were high for both methods, senior gynecologists performed better than residents, and postoperative imaging is still advised for thorough checking after the procedure.

Background: The association between the pattern of cortical thickness (CT) and executive dysfunction (ED) in mild cognitive impairment (MCI) and subjective cognitive complaints (SCC) is still poorly understood. We aimed to investigate the association between CT and ED in a large French cohort (MEMENTO) of 2323 participants with MCI or SCC.

Methods: All participants with available CT and executive function data (verbal fluency and Trail Making Test [TMT]) were selected (n=1924).

Purpose: Data published in the literature concerning the doses received by fetuses exposed to a 18 F-FDG PET are reassuring but were obtained from small and heterogeneous cohorts, and very few data are available concerning the fetal dose received after exposure to both PET and CT. The present study aimed to estimate the fetal dose received following a PET/CT exposure using methods that include anthropomorphic phantoms of pregnant women applied on a large cohort.

Patients And Methods: This retrospective multicenter study included 18 pregnant patients in the second and third trimesters.

Article Synopsis
  • Vascular disease is linked to dementia risk, and the study aims to clarify how specific markers like white matter hyperintensity (WMH), clinical stroke, and blood pressure (BP) contribute to this risk.
  • The research utilized a two-sample mendelian randomization approach and population-based studies, examining genetic influences on WMH, stroke, and BP in relation to Alzheimer's disease (AD) and all-cause dementia.
  • Findings suggest that a higher WMH burden is causally associated with an increased risk of AD, while certain blood pressure traits might offer a protective effect against dementia.

Background And Objectives: Elevated levels of Alzheimer disease (AD) blood-based biomarkers are associated with accelerated cognitive decline. However, their distinct relationships with specific cognitive and functional domains require further investigation. We aimed at estimating the associations between AD blood-based biomarkers and the trajectories of distinct cognitive and functional domains over a 5-year follow-up period.

Objective: Sacrospinous fixation is the gold standard procedure for management of apical pelvic organ prolapse by the vaginal route. However, there may be a relevant risk of neurovascular injury due to the proximity of neurovascular structures. We propose an anatomical study concerning the sacrospinous ligament with a new innovative minimally invasive technology using both a suture capturing device and a chip-on-the-tip endoscope to perform sacropinous fixation.

Objective(s): Many patients with Essure® implant may experience adverse events related to the device. Although local inflammation does not appear to be the pathophysiological mechanism underlying the symptoms, systemic inflammation could play a role. In the present study, as cytokines are involved in the inflammatory process, we proposed to investigate the profile of circulating and peritoneal cytokines.

Background And Objectives: Patients' comorbidities can affect Alzheimer disease (AD) blood biomarker concentrations. Because a limited number of factors have been explored to date, our aim was to assess the proportion of the variance in fluid biomarker levels explained by the clinical features of AD and by a large number of non-AD-related factors.

Methods: MEMENTO enrolled 2,323 individuals with cognitive complaints or mild cognitive impairment in 26 French memory clinics.
