A 51 year-old woman with vomitus, intermittent epigastric pain and heartburn had chronic sideropenic anemia. Gastroscopy revealed a subcardial, submucosal tumor. The tumor was removed totally by endoscopic polypectomy. Histologically it was identified as a carcinoid. The endocrinologic examination showed hypergastrinemia caused by chronic atrophic gastritis. The association of this gastric carcinoid with chronic atrophic gastritis type A, hypergastrinemia, hyperplasia of the gastrin-producing antral cells and micronodular hyperplasia of endocrine cells in the gastric fundus, confirms the hypothesis about the pathogenesis of these extremely rare gastric tumors.

Background: Alzheimer disease (AD) is a chronic progressive neurodegenerative disorder that presents with cognitive dysfunction, memory loss, language difficulties, emotion dysregulation, and the eventual loss of motor function and death. Magnetic resonance imaging (MRI) shows early atrophy in the medial temporal lobes, which then spreads to the posterior temporal lobe, parietal lobe, and finally the frontal lobe with relative sparing of the sensorimotor cortex. Social disadvantage has been shown to have potentially additive impacts on aging trajectories.

Method: We obtained whole-body 1.
Background: Chronic pain leads to tau accumulation and hippocampal atrophy in mice. Tau accumulation in the locus coeruleus (LC) precedes medial temporal accumulation in humans. Here we provide one of the first human studies examining the association of chronic pain with hippocampal volume, LC integrity, and Alzheimer's Disease (AD)-related plasma biomarkers.

Background: Brain aging is a complex process influenced by various genetic, lifestyle, and environmental factors, as well as by age-related and often co-existing pathologies. MRI and AI methods have been instrumental in understanding neuroanatomical changes that occur during aging in large and diverse populations.
Method: We leveraged Surreal-GAN, a state-of-the-art deep representation learning method, to elucidate the heterogeneity of brain aging by deriving dominant dimensions (patterns) of brain changes and examining their associations with various clinical and genetic factors.

Background: KLOTHO-VS heterozygosity (KL-VS) has been posited to be a protective factor against age-related disease and cognitive decline, having been associated with increased cortical volumes and brain connectivity, as well as improved cognition in healthy elderly individuals. Conversely, the APOE-ε4 allele is a primary risk factor for the development of Alzheimer's disease (AD), with ε4 carriers more likely to have greater β-amyloid burden, earlier age of AD onset, and accelerated rates of cognitive decline. Relatively few studies have investigated the interaction between these two genetic factors, with those that have presenting conflicting findings.
