Purpose of review Microaggressions are daily commonplace, subtle behaviors and attitudes toward others that arise from conscious or unconscious bias. Not only can microaggressions affect one's access to power, resources, and opportunity, but they could also contribute to the persistent disparities faced by marginalized groups among healthcare professionals as well as patients. Recent findings Physicians, especially those in perioperative specialties, commonly have distress during their medical training. Workplace mistreatment, such as discrimination, has been commonly reported by residents across multiple specialties. Microaggressions also impact patient care as they can influence decisions of medical professionals toward a person or group of people. Summary This review offers education on the correlation of microaggression and unconscious bias to health disparities, provides tools to address microaggressions as a bystander, and outlines processes for institutional improvement.

Methylenetetrahydrofolate reductase (MTHFR) deficiency is an autosomal recessive disorder with a spectrum of manifestations including neurological symptoms, premature arteriosclerosis, and venous and arterial thrombosis. Most patients are heterozygous for multiple MTHFR substitutions; small minorities are homozygous for mutations at this locus. Among these mutations, the C677T polymorphism is the most deleterious. Nitrous oxide use in anesthesia leads to significant increases in plasma homocysteine. We present a patient undergoing urgent surgery with a preoperative diagnosis of homozygous MTHFR deficiency.
