Evaluating prefrontal changes in depression using functional near-infrared spectroscopy utilizing Stroop test: A comparison with healthy controls.

Background: Functional near-infrared spectroscopy (fNIRS) is being increasingly utilized to visualize the brain areas involved in cognitive activity to understand the human brain better. Its portability and easy setup give it an advantage over other functional brain imaging tools. The current study utilizes fNIRS while performing a Stroop test, which is commonly used to assess the impairment of information selection in depression.

Metallic Bonding in Close-Packed Structures: Structural Frustration from a Hidden Gauge Symmetry.

Based on its simple valence electron configuration, we may expect lithium to have straightforward physical properties that are easily explained. However, solid lithium, when cooled below 77 K, develops a complex structure that has been debated for decades. A close parallel is found in sodium below 36 K where the crystal structure still remains unresolved.

Perceived Health Concerns and Barriers to Care in Persons With Overweight and Obesity: A Patient Survey.

Objectives: To identify patient characteristics, health concerns, and barriers to care based on overweight or obesity.

Methods: A 50-question anonymous survey was administered to patients. Data were compared by body mass index (BMI).

Splenic artery aneurysm and infarction during pregnancy from infective endocarditis.

Rheumatic heart disease (RHD) remains the leading cardiac problem affecting pregnant women, especially in low- to middle-income countries. In nearly one-third of the cases, it is detected during pregnancy when they present with complications. Infective endocarditis (IE) in pregnancy is rare, with an incidence of 1 in 100 000 pregnancies, and carries high maternal and fetal morbidity and mortality.
