A case of a 24-year-old woman with a 6 weeks lasting nodule of the right margin of the tongue is described. The nodule was 20 mm in diameter and showed surface ulceration. The diagnosis of low grade myofibroblastic sarcoma was supported by histological, immunohistochemical and electronmicroscopic examination. Although the tumor resection was not complete, the patient is free of disease 1 year after operation. The differential diagnostics of low grade myofibroblastic sarcoma is discussed.

Background: Despite data showing nutritional interventions high in antioxidant/anti-inflammatory properties (anthocyanin-rich foods such as blueberries/elderberries) may decrease risk of memory loss and cognitive decline, evidence for such effects in mild cognitive impairment (MCI) patients is limited. Therefore, we examined preliminary effects of American elderberry (Sambucus nigra canadensis) juice on cognition and inflammatory markers in MCI patients in a double-blind placebo-controlled trial.
Method: MCI patients (N = 24, M = 76.

There are few updated clinical practice guidelines available to assist clinicians with the assessment and management of BPSD, including deprescribing of medications. The Canadian Coalition for Seniors' Mental Health (CCSMH) developed Canadian clinical practice guidelines on the assessment and management of BPSD to address these needs.

Cold exposure has been historically used for medicinal purposes, but its benefits and associated mechanisms in mammalian organisms still remain unclear. Here, we explore the chemoprotective properties of cold temperature using a mouse model of hepatocellular carcinoma (HCC) that recapitulates several human features. Chronic cold exposure is shown to prolong lifespan in diseased mice, enhance liver health, and suppress the development of aggressive HCC, preventing hepatocellular hypertrophy, high-grade oval cell hyperplasia, liver steatosis, and aberrant hepatocyte hyperproliferation.
