Article Synopsis
- Older age at onset and reduced dopamine binding in the caudate region are key risk factors for cognitive decline in Parkinson's disease (PD).
- A study of 128 drug-naive PD patients showed that baseline dopamine dysfunction correlates with cognitive performance and these factors can independently predict cognitive changes over 7 years.
- The research highlights that the caudate exhibits a greater age-related decline in dopamine binding compared to the putamen, suggesting a unique susceptibility in older PD patients to cognitive impairment.
Lymphadenectomy represents a fundamental step in the staging and treatment of non-small cell lung cancer (NSCLC). To date, the extension of lymphadenectomy in early-stage NSCLC is a debated topic due to its possible complications. The detection of sentinel lymph nodes (SLNs) is a strategy that can improve the selection of patients in which a more extended lymphadenectomy is necessary.

In recent years, some studies have also explored the possibility that FDG-PET could have a prognostic role.

In this review, we explore the role of radiomics in reshaping our understanding of pediatric sarcomas, emphasizing methodological considerations and applications such as diagnostics and predictive modeling. A systematic review conducted up to November 2023 identified 72 papers on radiomics analysis in pediatric sarcoma from PubMed/MEDLINE, Web of Knowledge, and Scopus.

Preoperative imaging included CT, PET/CT with 68 Ga-DOTATOC, and SPECT/CT with 99m Tc-HYNICTOC. These scans revealed morphological and functional properties of the primary tumor localized in the ileum.
