Memory precision and age differentially predict the use of decision-making strategies across the lifespan.

Memory function declines in normal aging, in a relatively continuous fashion following middle-age. The effect of aging on decision-making is less well-understood, with seemingly conflicting results on both the nature and direction of these age effects. One route for clarifying these mixed findings is to understand how age-related differences in memory affect decisions.

Marijuana and the hippocampus: A longitudinal study on the effects of marijuana on hippocampal subfields.

The psychoactive effects of cannabis, one of the most commonly used narcotics, have been documented extensively. Despite multiple studies being undertaken, there have been only a few longitudinal studies investigating the effect of long term usage of cannabis on various subcortical structures. This study aims at looking deeper into the effects of long term usage of cannabis on different hippocampus subfields.

New and emerging therapies in treatment of Clostridium difficile infection.

Clostridium difficile infection (CDI) represents one of the most serious nosocomial infections that have grown dramatically over the past decade. Vancomycin and metronidazole are currently used as a standard therapy for CDI. Metronidazole is recommended as a first-line therapy for mild-to-moderate infections and vancomycin is mainly used for severe and/or refractory cases.

Role of cannabis in digestive disorders.

Cannabis sativa, a subspecies of the Cannabis plant, contains aromatic hydrocarbon compounds called cannabinoids. [INCREMENT]-Tetrahydrocannabinol is the most abundant cannabinoid and is the main psychotropic constituent. Cannabinoids activate two types of G-protein-coupled cannabinoid receptors: cannabinoid type 1 receptor and cannabinoid type 2 receptor.

Isolated axillary lymph node metastasis from serous ovarian cancer.

A 68-year-old female with past medical history of stage IIIc serous ovarian cancer after cytoreductive surgery and adjuvant chemotherapy came to clinic for regular follow-up visit. Physical examination was completely normal except for an isolated left axillary lymph node enlargement. Patient's abdominal sonogram and CT scan of abdomen and pelvis did not show any other new metastasis.

A rare cause of acute pancreatitis: intramural duodenal hematoma.

We describe an interesting case of intramural duodenal hematoma in an otherwise healthy male who presented to emergency room with gradually progressive abdominal pain, nausea, and vomiting. This condition was missed on initial evaluation and patient was discharged from emergency room with diagnosis of acute gastritis. After 3 days, patient came back to emergency room and abdominal imaging studies were conducted which showed that patient had intramural duodenal hematoma associated with gastric outlet obstruction and pancreatitis.
