Randomized Controlled Trial Comparative Study
Procalcitonin vs C-reactive protein as predictive markers of response to antibiotic therapy in acute exacerbations of COPD.
Rational prescription of antibiotics in acute exacerbations of COPD (AECOPD) requires predictive markers. We aimed to analyze whether markers of systemic inflammation can predict response to antibiotics in AECOPD. ⋯ Contrary to the current literature, this study suggests that patients with low PCT values do benefit from antibiotics. CRP might be a more valuable marker in these patients.

ICUs are experiencing an epidemic of patients with acute brain dysfunction (delirium) and weakness, both associated with increased mortality and long-term disability. These conditions are commonly acquired in the ICU and are often initiated or exacerbated by sedation and ventilation decisions and management. Despite > 10 years of evidence revealing the hazards of delirium, the quality chasm between current and ideal processes of care continues to exist. ⋯ Individual components of this bundle are evidence based and can help standardize communication, improve interdisciplinary care, reduce mortality, and improve cognitive and functional outcomes. We refer to this as the "ABCDE bundle," for awakening and breathing coordination, delirium monitoring, and exercise/early mobility. This evidence-based bundle of practices will build a bridge across the current quality chasm from the "front end" to the "back end" of critical care and toward improved cognitive and functional outcomes for ICU survivors.

Pleuroscopy, also known as medical thoracoscopy, is a minimally invasive procedure to inspect and perform a biopsy of the pleural space as well as to perform therapeutic interventions. It differs from conventional video-assisted thoracic surgery in that it may be performed under moderate sedation in the endoscopy suite without the need for intubation or single-lung ventilation. ⋯ Therapeutic interventions, such as chemical pleurodesis, may be performed during pleuroscopy for recurrent, symptomatic malignant pleural effusions, with success rates approaching 90%. In trained hands, pleuroscopy is a safe and well-tolerated procedure with high diagnostic accuracy and therapeutic efficacy.

Randomized Controlled Trial Comparative Study
Prevalence and recognition of obstructive sleep apnea in Chinese patients with type 2 diabetes mellitus.
Obstructive sleep apnea (OSA) is associated with disorders of glucose metabolism. Previous studies revealed a high prevalence of OSA among subjects with type 2 diabetes mellitus (DM). The aims of this study were to determine the prevalence of OSA and associated clinical factors in Chinese patients with DM. ⋯ In conclusion, OSA is more prevalent in Chinese adults with DM than in the general population. A high index of suspicion for OSA in patients with DM is warranted, because they may not have overt daytime sleepiness.

Cutaneous ear lobe Pco₂ at 37°C to evaluate microperfusion in patients with septic shock.
Tissue hypercarbia is related to hypoperfusion and microcirculatory disturbances in patients with septic shock. Transcutaneous Pco₂ devices using a heated sensor to arterialize the tissue have been used as an alternative method for estimation of Paco₂. This study investigates whether a cutaneous sensor attached to an ear lobe and regulated to 37°C could be used to measure cutaneous Pco₂ (Pcco₂) and evaluate microperfusion in patients with septic shock. ⋯ Ear lobe cutaneous Pco₂ at 37°C represents a noninvasive technique to assess tissue Pco₂ measurement. Pc-aco₂ and Pc-etco₂ were related to outcome and provide continuous information on microperfusion in patients with septic shock.
