The dark side of the fibroblastic sleeve: Case report and literature review.

The fibroblastic sleeve is a structure potentially enveloping any intravascular device. At ultrasound scan, it typically presents as a thin layer of variably echogenic material covering the catheter surface, which usually tends to remain into the vessel after the catheter removal. However, several case reports have documented its migration toward the heart or pulmonary artery after a central venous catheter removal.

Pregnancy Outcomes from a Multidisciplinary Obstetric-Medicine/Rheumatology Clinic in the United States: A Five-Year Retrospective Analysis.

Objective: At Women & Infants Hospital in Providence, Rhode Island, the Specialty Care in Pregnancy clinic combines obstetric-medicine internists with rheumatologists to care for pregnant patients with rheumatologic conditions. These clinics are scarce, with only three known similar clinics in the United States. This study aims to characterize the population cared for in this clinic, identify interventions, and analyze pregnancy outcomes for the birthing parents and newborns.

Insulin and leptin oscillations license food-entrained browning and metabolic flexibility.

Timed feeding drives adipose browning, although the integrative mechanisms for the same remain unclear. Here, we show that twice-a-night (TAN) feeding generates biphasic oscillations of circulating insulin and leptin, representing their entrainment by timed feeding. Insulin and leptin surges lead to marked cellular, functional, and metabolic remodeling of subcutaneous white adipose tissue (sWAT), resulting in increased energy expenditure.
