Leptin potentiates bone loss at skeletal sites distant from focal inflammation in female ob/ob mice.

Leptin increases focal inflammation and osteolysis induced by polyethylene particles in leptin-deficient ob/ob mice suggesting the adipokine, an important immune modulator, contributes to orthopedic implant failure. Focal inflammation leads to bone loss at distant skeletal sites, and it is plausible that leptin also contributes to this response. We tested this possibility in 6-week-old female ob/ob mice (6-8/group) by evaluating bone architecture, turnover, and gene expression 12 days following surgical placement of polyethylene particles over calvaria.

Anesthesia Trauma Guidelines: A Systematic Review of Global Accessibility and Quality.

This systematic review describes the available clinical practice guidelines (CPGs) for the anesthetic management of trauma and appraises the accessibility and quality of these resources. This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search was conducted across 8 databases (MEDLINE, Embase, Web of Science, CABI Digital Library, Global Index Medicus, SciELO, Google Scholar, and National Institute for Health and Care Excellence) for guidelines from 2010 to 2023.

Primary medullary adenocarcinoma of the colon: Literature review and case series.

Aims: Medullary carcinoma of the colon is a rare subtype of adenocarcinoma, first described in 1999. Clinically known to have a favourable prognosis in comparison to poorly differentiated cancers, it is associated with deficient mismatch repair. This is an observational single center study of patients with medullary cancer, and comparison with the current literature.

Basolateral amygdala volume in affective disorders using 7T MRI .

Background: The basolateral complex of the amygdala is a crucial neurobiological site for Pavlovian conditioning. Investigations into volumetric alterations of the basolateral amygdala in individuals with major depressive disorder (MDD) have yielded conflicting results. These may be reconciled in an inverted U-shape allostatic growth trajectory.
