The Role of Exosomes in Medical Dermatology: Literature Review and Update.

Background: Exosomes are extracellular vesicles, composed of a phospholipid bilayer, that are primarily derived from stem cells. The contents of exosomes can be incorporated into the tissue in which they are introduced, which presents a unique therapeutic option.

Aims: Exosomes have been investigated as a treatment for a number of medical ailments, but the literature supporting these indications is inconclusive.

Exosomes: Historical Evolution and Emerging Roles in Dermatology.

Background: Exosomes are a nanoscale extracellular vesicles derived from different cell types that have been investigated for various clinical applications, including functioning as biomarkers and use as direct therapeutics. Given the role of exosomes in multiple pathophysiologic pathways and potential practical applications, they have garnered significant interest in the scientific community but much is still unknown about their development and use.

Aims: This literature review covers the background, mechanisms of action, use as biomarkers, methods of application, and direct therapeutic applications of exosomes.

Exosomes for Aesthetic Dermatology: A Comprehensive Literature Review and Update.

Background: Exosomes are nanoscale vesicles derived from various cell types and tissues that have many potential applications, generating great interest from researchers. One particularly intriguing application of exosomes is their use as a direct therapeutic for aesthetic indications. Several studies and case reports have explored the impact of exosomes for numerous cosmetic concerns but a consensus on the outcomes of these studies has not been established.

Perinatal psychotropic dispensing: A descriptive population-based study in New Zealand.

Introduction: Decisions about using psychotropics during pregnancy are complex as risks of untreated illness are balanced against risks of fetal exposure to medication. The objective was to describe perinatal psychotropic dispensing patterns in New Zealand.

Methods: Nationwide data from the New Zealand National Maternity Collection between January 1, 2011 and December 31, 2017 identified 399 715 pregnancies.

Validation of the HULL Score clinical prediction rule for unsuspected pulmonary embolism in ambulatory cancer patients.

Background: Clinical prediction rules (CPRs) developed to predict adverse outcomes of suspected pulmonary embolism (PE) and facilitate outpatient management have limitations in discriminating outcomes for ambulatory cancer patients with unsuspected PE (UPE). The HULL Score CPR uses a 5‑point scoring system incorporating performance status and self-reported new or recently evolving symptoms at UPE diagnosis. It stratifies patients into low, intermediate and high risk for proximate mortality.
