Objective: To analyze the influencing factors of male cutaneous melanoma (CM) patients dying from genitourinary diseases (GUD).
Methods: We searched the surveillance, epidemiology, and end results (SEER) database and extracted data on male CM patients according to the inclusion and exclusion criteria, including male patients whose cause of death was CM (cohort A) or GUD (cohort B). Comparisons between the two cohorts were performed before and after propensity score matching (PSM). An interaction analysis between age and year of diagnosis was also conducted. Cox regression analysis were performed to find the risk factors for death from GUD.
Results: Seven thousand seventy-eight CM patients were included, including 6415 (90.6%) in cohort A and 663 (9.4%) in cohort B. Compared with cohort A, cohort B patients were older (median age 74 ys. vs 65 ys.) and were more under the localized stage and had longer survival time no matter before or after PSM (all p<0.001). The stage was an inhibitory factor for cohort B (p <0.001). After PSM, only age and year of diagnosis were found to be cohort B's promoting factors (p<0.001). The interaction analysis showed that older patients diagnosed in later years (2009-2020) had a higher risk of dying from GUD compared to those diagnosed earlier (p<0.05). Patients with a later year of diagnosis (2009-2020) had a lower median survival time than patients with an earlier year of diagnosis (2000-2008) (p<0.001). When the patient's year of diagnosis was earlier (2000-2008), older patients (>75 ys.) had a higher risk of dying from GUD than younger patients (≤75 ys.) (p<0.001).
Conclusion: We first reported a significant interaction between age and year of diagnosis in male CM patients dying from GUD, highlighting the increased risk in older patients diagnosed more recently. We may pay attention to the possibility of dying from genitourinary diseases for CM patients.

Background: Seizures in Alzheimer's Disease (AD) are increasingly recognized to occur and can increase cognitive decline and reduce survival compared to unaffected age-matched peers (Lyou et al. 2018). Administration of antiseizure medicines (ASMs) to AD patients with epileptiform activity may improve cognition (Vossel et al.

Background: Microbiota of the distal part of the intestine produces Urolithin A (Uro A) as a derivative of ellagitannins hydrolysis. Recently, the mitophagy, anti-inflammatory, and antioxidant properties of Uro A have focused more attention on its probable beneficial effects on neurodegenerative states. The purpose of this research was to study the impact of Uro A on the histopathology of the cerebellum in a rat model of streptozotocin-induced Alzheimer's disease.

Background: Mivelsiran (ALN-APP) is an investigational, intrathecally administered RNA interference therapeutic designed to lower levels of amyloid-β (Aβ) peptide, a key driver of Alzheimer's disease (AD) and cerebral amyloid angiopathy (CAA) pathogenesis, by reducing upstream production of amyloid precursor protein (APP). We report additional safety, pharmacodynamic, and biomarker data from the double-blind, placebo-controlled, single ascending dose part of the ongoing mivelsiran Phase 1 study (NCT05231785).

Background: Effect and Safety of Electroconvulsive Therapy plus Usual Care for the Acute Management of Severe Agitation in Dementia (ECT-AD) is a multi-site NIA-funded FDA-regulated pioneering clinical trial to investigate the effectiveness of electroconvulsive therapy (ECT) in treating severe and treatment-refractory agitation and aggression among individuals with advanced dementia, a condition that has a profound negative impact on patient quality of life and caregiver burden. Here we present baseline demographics of the patient population in this ongoing trial.
Method: To date we have enrolled 18 participants, with a mean age of 74.

Background: Prodromal Alzheimer's disease (AD) clinical trials of candidate treatments enroll individuals with mild cognitive impairment (MCI) and biomarker evidence of AD. These trials require co-enrollment with a study partner and complex decision-making, weighing potential risks and benefits of participation. Some patients with MCI lack capacity to provide trial informed consent.
