Medwire News (7/21, McDermid) reports, “The presence of an eating disorder diagnosis significantly increases the risk for diabetic ketoacidosis (DKA) and all-cause mortality in adolescents and young adults with type 1 diabetes [T1D],” researchers concluded after using “health records to identify 20,035 adolescents and young adults (aged 10–39 years) with type 1 diabetes, 0.8% of whom had an eating disorder diagnosis.” The study authors concluded. “It is important to incorporate screening tools for disordered eating behavior into routine type 1 diabetes care to allow for timely identification of such patients and to consider eating disorders as a reason for poor glycemic control, potentially due to insulin withholding.” The findings were published online in Diabetes Care.

Psychiatric News (7/20) reports researchers have provided “a comprehensive overview of the neurological and psychiatric impact of the COVID-19 pandemic.” They did so by compiling “data from individual case reports, cohort studies, and meta-analyses on the neurological and psychiatric outcomes in patients with SARS-CoV-2 infection.” The study authors observed, “CNS infection combined with environmental stress caused by pandemic fear, social and financial restrictions, and ICU monitoring may result in the development of neuropsychiatric symptoms or syndromes, including depressive symptoms or episodes, manic or hypomanic symptoms or episodes, psychotic symptoms, obsessive-compulsive symptoms, and posttraumatic stress.” The findings were published online July 19 in the Journal of Neuropsychiatry and Clinical Neurosciences, a publication of the American Psychiatric Association.
