Food Desert Residence Is Not Associated With Dietary Adherence or Complication Rates in Patients With Isolated Mandibular Fractures.

Background: Mandible fracture management requires postoperative dietary modifications to promote healing. Over 20 million Americans live in food deserts, low-income neighborhoods over one mile from a grocery store. The relationship between food desert residence (FDR) and adherence to postoperative dietary instructions remains unexplored.

Gastric half emptying time (T ) for 4-h gastric emptying scintigraphy simplifies reporting but reduces detection of gastroparesis.

Background: Gastric emptying scintigraphy (GES) reports percent retention at 1, 2, and 4 h. Time to empty half the meal (T ) could simplify GE reporting.

Aims: To compare the performance of GES T to 1-, 2-, and 4-h retention.

Reconstructing the genetic history of Italians: new insights from a male (Y-chromosome) perspective.

Background: Due to its central and strategic position in Europe and in the Mediterranean Basin, the Italian Peninsula played a pivotal role in the first peopling of the European continent and has been a crossroad of peoples and cultures since then.

Aim: This study aims to gain more information on the genetic structure of modern Italian populations and to shed light on the migration/expansion events that led to their formation.

Subjects And Methods: High resolution Y-chromosome variation analysis in 817 unrelated males from 10 informative areas of Italy was performed.

Exome sequencing in schizophrenic patients with high levels of homozygosity identifies novel and extremely rare mutations in the GABA/glutamatergic pathways.

Inbreeding is a known risk factor for recessive Mendelian diseases and previous studies have suggested that it could also play a role in complex disorders, such as psychiatric diseases. Recent inbreeding results in the presence of long runs of homozygosity (ROHs) along the genome, which are also defined as autozygosity regions. Genetic variants in these regions have two alleles that are identical by descent, thus increasing the odds of bearing rare recessive deleterious mutations due to a homozygous state.
