Iron regulatory protein 2 (IRP2), a post-transcriptional regulator of cellular iron metabolism has been associated with susceptibility to chronic obstructive pulmonary disease (COPD). Resistive breathing (RB) is the hallmark of the pathophysiology of obstructive airway diseases, especially during exacerbations, where increased mechanical stress is imposed on the lung. We have previously shown that RB, through tracheal banding, mimicking severe airway obstruction, induces pulmonary inflammation and injury in previously healthy mice.

Skeletal muscles contain lipids inside and outside cells, namely intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL), respectively; lipids have also been found to be interspersed between these muscles as adipose tissue, namely intermuscular adipose tissue (IMAT). Metabolized IMCL has been recognized as an important substrate for energy production and their metabolism is determined by the muscle oxidative capacity. Therefore, it has been speculated that muscle oxidative capacity is related to muscle lipid content.

Self-Diagnosed Cases of Dissociative Identity Disorder on Social Media: Conceptualization, Assessment, and Treatment.

Harv Rev Psychiatry

December 2024

From School of Social Sciences, University of New South Wales (Dr. Salter); Department of Psychology, Towson University (Dr. Brand); Harvard Medical School (Dr. Robinson); School of Medicine, University of Maryland (Dr. Loewenstein); The Leadership Council on Child Abuse & Interpersonal Violence, Towson, MD (Dr. Silberg); Faculty of Health Sciences, McMaster University (Dr. Korzekwa).

Recent global popularity of social media content about dissociative identity disorder (DID) has coincided with increased self-diagnosis among children and young people who have formed large online communities and presented in clinical settings seeking to affirm their self-diagnoses. We situate this phenomenon within a broader trend toward self-diagnosis due to the widespread visibility and accessibility of mental health content on social media. Social media propelled self-diagnosis raises particular questions for the study and treatment of DID due to long-standing debates over whether the condition is traumagenic, sociogenic, or iatrogenic.
