Comparative Study
Optoelectronic plethysmography as an alternative method for the diagnosis of unilateral diaphragmatic weakness.
The objective was to determine whether optoelectronic plethysmography (OEP) can detect asymmetric ventilation related to unilateral or asymmetric diaphragmatic weakness, suggesting usefulness as a diagnostic tool. ⋯ OEP detected asymmetric ventilation in all patients diagnosed with unilateral diaphragm weakness and in no patients without this diagnosis. Thus, OEP is an effective noninvasive alternative that is preferred by the patients over CMAP response and latPdiTw.

Review Meta Analysis
Bidirectional Associations Between Clinically Relevant Depression or Anxiety and COPD: A Systematic Review and Meta-analysis.
The longitudinal associations between depression or anxiety and COPD, and their comorbid effect on prognosis, have not been adequately addressed by previous reviews. We aimed to systematically assess these associations to inform guidelines and practice. ⋯ Depression and anxiety adversely affect prognosis in COPD, conferring an increased risk of exacerbation and possibly death. Conversely, COPD increases the risk of developing depression. These bidirectional associations suggest potential usefulness of screening for these disease combinations to direct timely therapeutic intervention.
