A 33-year-old woman experienced 90 min of in-hospital cardiac arrest following an intentional overdose of anhydrous caffeine powder. In the face of prolonged and apparently futile resuscitation attempts, high-dose insulin euglycemic therapy was initiated. ⋯ The patient recovered full neurologic function and survived to discharge. Although high-dose insulin is effective in beta-blocker, calcium channel blocker, and tricyclic antidepressant overdose, this is seemingly the first description of its successful use in caffeine toxicity.

COPD is a heterogeneous syndrome. Many COPD subtypes have been proposed, but there is not yet consensus on how many COPD subtypes there are and how they should be defined. The COPD Genetic Epidemiology Study (COPDGene), which has generated 10-year longitudinal chest imaging, spirometry, and molecular data, is a rich resource for relating COPD phenotypes to underlying genetic and molecular mechanisms. ⋯ Third, COPD phenotypes identified or prioritized through machine learning methods have led to novel biological discoveries, including novel emphysema genetic risk variants and systemic inflammatory subtypes of COPD. Fourth, trajectory-based COPD subtyping captures differences in the longitudinal evolution of COPD, addressing a major limitation of clustering analyses that are confounded by disease severity. Ongoing longitudinal characterization of subjects in COPDGene will provide useful insights about the relationship between lung imaging parameters, molecular markers, and COPD progression that will enable the identification of subtypes based on underlying disease processes and distinct patterns of disease progression, with the potential to improve the clinical relevance and reproducibility of COPD subtypes.

EVALUATION OF CHANGES IN CONTROL STATUS IN COPD: AN OPPORTUNITY FOR EARLY INTERVENTION: Control status is useful for clinical assessment.
Control has been proposed as a dynamic tool that can capture changes in the clinical status of patients with COPD. ⋯ In only 3 months, almost one-third of patients experienced changes in their control status. Changes in control status were significantly more frequent than changes in phenotype, risk level, and GOLD stage, and resulted in significant changes in health status.

As the population ages, and more patients with chronic pulmonary diseases become frail and functionally impaired, the prevalence of homebound patients grows. Homebound patients have higher disease burden, inpatient utilization rates, and mortality than nonhomebound patients. Vulnerable homebound patients with pulmonary disease benefit from pulmonary expertise to evaluate and optimize their complex medication regimens; evaluate equipment such as nebulizers, home oxygen, ventilators, and suction machines; and coordinate services. ⋯ We also explore the logistics of making house calls part of pulmonary practice, including supplies needed, safety in the home, and reimbursement. Reimbursement has grown for house calls, and we review how to bill for visits, advance care planning, and care management that is often required when caring for patients with advanced illness. In addition, house calls can often be beneficial for patients who may be identified as high risk and are part of value-based agreements with payers.
