We present the case of a 50-year-old woman affected by a rectal gastrointestinal stromal tumor (GIST), with a recurrence in pre-sacral and pre-coccygeal space after surgery and Imatinib therapy. GISTs are the most common mesenchymal tumors of the gastrointestinal tract and rectal GISTs are rare (only 2% of cases); magnetic resonance and computed tomography are the main imaging techniques for diagnosis and follow-up, while ultrasound and contrast-enhanced ultrasound may be useful to perform a percutaneous biopsy, as in the case presented: the imaging features of the lesion in all these imaging methods are displayed.

Real-World data platforms for Alzheimer's Disease (AD) offer a unique opportunity to improve health equity through better understanding of health disparities and inclusivity in research, which is critical to translatability of research findings. AD research in the US and globally remains largely inaccessible to many individuals due to individual-level, study-level, investigator-level and larger systemic barriers. ALZ-NET, a US-based registry to evaluate longitudinal outcomes of patients being evaluated for or treated with novel FDA-approved AD therapy, and New IDEAS, an observational US-based longitudinal study of amyloid PET clinical utility, both offer opportunities for examining care, inclusivity, and disparities.

Background: We report the case of a 79-year-old woman with Alzheimer's disease who enrolled in a clinical study of lecanemab. After the third, biweekly infusion she suffered a seizure followed by aphasia and progressive encephalopathy. Magnetic resonance imaging revealed multifocal cerebral edema and an increased burden of cerebral microhemorrhages compared to pre-trial imaging.

Background: Clinical Dementia Rating (CDR) and its evaluation have been important nowadays as its prevalence in older ages after 60 years. Early identification of dementia can help the world to take preventive measures as most of them are treatable. The cellular Automata (CA) framework is a powerful tool in analyzing brain dynamics and modeling the prognosis of Alzheimer's disease.

Background: The Sino-nasal Outcome Test (SNOT-22) is a 22-question survey that is utilized to evaluate health-related quality of life of patients with chronic rhinosinusitis (CRS). The Patient Global Impression Symptom Severity (PGISS) is a similar yet versatile instrument that combines features of both a Likert scale and a visual analog to assess symptom severity in CRS patients. While previous studies have evaluated the validity of SNOT-22 as an instrument to measure CRS patients' symptom severity, no studies have evaluated PGISS scale's ability to evaluate and guide treatment plans for CRS patients.
