Case ReportsBrain Responses to Propofol in Advance of Recovery From Coma and Disorders of Consciousness: A Preliminary Study.
Rationale: Predicting recovery of consciousness in unresponsive, brain-injured individuals has crucial implications for clinical decision-making. Propofol induces distinctive brain network reconfiguration in the healthy brain as it loses consciousness. In patients with disorders of consciousness, the brain network's reconfiguration to propofol may reveal the patient's underlying capacity for consciousness. ⋯ Measurements and Main Results: The adaptive reconfiguration index was significantly higher in patients who later recovered full consciousness (U value = 21, P = 0.008) and able to discriminate with 100% accuracy whether the patient recovered consciousness. Conclusions: The adaptive reconfiguration index of patients who recovered from a disorder of consciousness at 3-month follow-up was linearly separable from that of patients who did not recover or remained in a chronic disorder of consciousness on the single-subject level. EEG and propofol can be administered at the bedside with few contraindications, affording the adaptive reconfiguration index tremendous translational potential as a prognostic measure of consciousness recovery in acute clinical settings.

Comparative StudyResources and Geographical Access to Care for Severe Pediatric Pneumonia in Four Resource-Limited Settings.
Rationale: Pneumonia is the leading cause of death in children worldwide. Identifying and appropriately managing severe pneumonia in a timely manner improves outcomes. Little is known about the readiness of healthcare facilities to manage severe pediatric pneumonia in low-resource settings. ⋯ Conclusions: Most healthcare facilities in low-resource settings of the HAPIN study area were inadequately resourced to care for severe pediatric pneumonia. Early identification of cases and timely referral is paramount. The provision of pulse oximeters to all health facilities may be an effective approach to identify cases earlier and refer them for care and in a timely manner.

Comparative StudyEfficacy of Inhaled Treprostinil on Multiple Disease Progression Events in Patients with Pulmonary Hypertension Due to Parenchymal Lung Disease in the INCREASE Trial.
Rationale: The INCREASE study of inhaled treprostinil met its primary endpoint of change in 6-minute-walk distance at Week 16. In addition, there were significantly fewer clinical worsening events in patients receiving inhaled treprostinil. However, the incidence of multiple events in the same patient is unknown. ⋯ Fewer patients receiving inhaled treprostinil had multiple progression events compared with those receiving the placebo (35 vs. 58, 22% vs. 36%; P = 0.005). Conclusions: Patients who received inhaled treprostinil were significantly less likely to experience further disease progression events after an initial event compared with patients receiving placebo. These results support the continuation of inhaled treprostinil despite the occurrence of disease progression in clinical practice.
