Evidence regarding the association between sarcopenia (skeletal muscle depletion) and outcomes in patients with lung cancer varies across studies. We aimed to systematically review the prognostic value of sarcopenia in lung cancer. ⋯ Sarcopenia is highly prevalent in patients with lung cancer (approximately one in two) and an important predictor of impaired OS in patients with SCLC or with different stages of NSCLC.

Effect of Pulmonary Rehabilitation on Symptoms of Anxiety and Depression in COPD: A Systematic Review and Meta-Analysis.
Pulmonary rehabilitation (PR) improves exercise capacity and quality of life in people with COPD; however, its effect on anxiety and depression symptoms is less clear. Existing data are difficult to apply to clinical PR because of diverse interventions and comparators. This review evaluated the effectiveness of PR on anxiety and depression symptoms in people with COPD. ⋯ PR confers significant, clinically relevant benefits on anxiety and depression symptoms. Because further studies involving no treatment control groups are not indicated, these robust estimates of treatment effects are likely to endure.

Epilepsy is the fourth most common neurologic disorde in the United States, affecting over 2.2 million people. Epilepsy is associated with a number of medical and psychiatric comorbidities, higher health-care use and cost, and substantial economic burden. OSA is twofold more common in adults with epilepsy than in age-matched control subjects, and the incidence increases with age. ⋯ Vagus nerve stimulation is a form of neuromodulation for drug-resistant focal epilepsy. When the device activates during sleep it causes reduction in airflow and respiratory effort, airflow obstruction, and oxygen desaturations, sometimes producing a clinical sleep apnea syndrome. The goal of this review is to discuss firmly established and recently recognized clinical, neurobiologic, electrophysiologic, and polysomnographic relationships between sleep-disordered breathing and epilepsy.
