Comparative Study
Usefulness of admission red blood cell distribution width as a predictor of severity of acute pulmonary embolism.
Previous researches have represented a considerable relation between acute pulmonary embolism (PE) and red blood cell distribution width (RDW). To the authors' knowledge no research has been informed in subjects with PE severity. Pulmonary arterial obstruction index (PAOI) is associated with the severity of acute PE. ⋯ PAOI was correlated with PE severity, D-dimer level, sPAP and clinical probability scores. PAOI was correlated with RDW levels. RDW levels, an inexpensive and easily measurable laboratory factor, were considerable associated with the severity and presence of PE.

Comparative Study
The declined levels of inflammatory cytokines related with weaning rate during period of septic patients using ventilators.
Approximately 50% of patients with sepsis-induced acute lung injury and acute respiratory distress syndrome require mechanical ventilation. Patients with extended mechanical ventilator use routinely develop reinfections, which increases hospital stay, mortality, and health care cost. Some studies have pointed out inflammatory factors concentrations can affect ventilator weaning, but do not indicate changed inflammatory factors related to ventilator weaning during using ventilators. ⋯ The factors of ventilators weaning successfully such as disease control, nutritional status, and so on. The declined levels of serum inflammatory cytokines, especially IL-6, improved inflammation status might be one factor of successfully weaning during septic patients on ventilators.

Radiologic computed tomography features of Mycobacterium abscessus in cystic fibrosis.
Mycobacterium abscessus infection in cystic fibrosis (CF) patients can lead to poor outcomes. Early diagnosis is important, but there are no studies outlining specific imaging features of M. abscessus in CF. ⋯ The most common CT features of early M. abscessus in our CF population include bronchiectasis, mucus plugging, and consolidation, but the findings did not reveal a unique radiologic signature. CT at this initial time point may not distinguish early M. abscessus infection from background lung disease or mycobacterial colonization in CF patients.

The co-existence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) is a common phenomenon referred to as overlap syndrome (OS). In this study, we evaluated the prevalence of OS in mild hypoxemic COPD patients without OSA symptoms and compared characteristics of OS and COPD patients. ⋯ This findings support that high prevalence (58%) of OS in COPD patients without OSA symptoms is related to BMI. Therefore, sleep study should be considered in especially overweight or obese COPD patients, even in those without sleep apnea symptoms.

Determining the optimal time for performing a tracheostomy and weaning a patient off a ventilator is typically challenging for physicians, respiratory therapists, patients and patients' families. ⋯ Tracheostomy timing was strongly correlated with ventilator weaning. Early tracheostomy was higher successful ventilator weaning rates. The surgical patients were more likely to receive an early tracheostomy. However, the number of patients in Taiwan who received tracheostomies was lower than that in other countries. Further study maybe need to understand cultural variations in the acceptance of tracheostomies by patients.
