Buprenorphine differentially alters breathing among four congenic mouse lines as a function of dose, sex, and leptin status.

The opioid buprenorphine alters breathing and the cytokine leptin stimulates breathing. Obesity increases the risk for respiratory disorders and can lead to leptin resistance. This study tested the hypothesis that buprenorphine causes dose-dependent changes in breathing that vary as a function of obesity, leptin status, and sex.

Analysis of Medical Error Contributing to Missed Acute Myeloid Leukemia Diagnosis.

Hospitals and physicians attempt to minimize medical error by putting systems checks and balances in place at multiple levels. The effectiveness of these hospital-specific strategies to thwart error is called into question, as medical error remains a leading cause of death in the United States. This case report outlines the course of a 62-year-old man with a history of non-small cell lung cancer and right tongue squamous cell carcinoma, who had been admitted to an outside hospital for possible pneumonia.

Buprenorphine Depresses Respiratory Variability in Obese Mice with Altered Leptin Signaling.

Background: Opiate-induced respiratory depression is sexually dimorphic and associated with increased risk among the obese. The mechanisms underlying these associations are unknown. The present study evaluated the two-tailed hypothesis that sex, leptin status, and obesity modulate buprenorphine-induced changes in breathing.
