Understanding and Preventing Advanced Gastric Cancer in Young Hispanic Patients.

The risk of gastric cancer among immigrants from countries where Helicobacter pylori is endemic greatly exceeds those born in the United States. Among patients in the Los Angeles safety-net health system, the risk of advanced and fatal gastric cancer is higher in Hispanic versus non-Hispanic patients. There is an urgent need to define whether this reflects concomitant illnesses, such as metabolic disease, occupational exposures, or differential access to H.

Convergent molecular signatures across eating disorders and obsessive-compulsive disorder in the human brain.

Eating disorders (ED) and obsessive-compulsive disorder (OCD) exhibit significant clinical and genetic overlap, yet their shared molecular mechanisms remain unclear. We conducted a transcriptomic investigation of the dorsolateral prefrontal cortex (DLPFC) and caudate from 86 controls, 57 ED, and 27 OCD cases. ED was associated with robust differentially expressed genes (DEGs): 102 DEGs the DLPFC and 222 in the caudate (FDR < 1%) and replicated in an independent cohort.

Skipping of Exon 20 in EP300: A Novel Variant Linked to Rubinstein-Taybi Syndrome With Atypical and Severe Clinical Manifestations.

Rubinstein-Taybi syndrome (RSTS) is a rare autosomal dominant neurodevelopmental disorder linked to haploinsufficiency of CREBBP (RSTS1) and EP300 (RSTS2) genes. Characteristic features often include distinctive facial traits, broad thumbs and toes, short stature, and various degrees of intellectual disability. The clinical presentation of RSTS is notably variable, making it challenging to establish a clear genotype-phenotype correlation, except for specific variants which cause the allelic Menke-Hennekam syndrome.
