Comparative Study
Pulmonary function and survival in idiopathic versus secondary usual interstitial pneumonia.
The usual interstitial pneumonia (UIP) pattern of lung injury may occur in the setting of connective tissue disease (CTD), but it is most commonly found in the absence of a known cause, in the clinical context of idiopathic pulmonary fibrosis (IPF). Our objective was to observe and compare longitudinal changes in pulmonary function and survival between patients with biopsy-proven UIP found in the clinical context of either CTD or IPF. ⋯ Despite no significant differences in changes in pulmonary function over time, patients with CTD-UIP (at least those with certain classifiable CTDs) live longer than patients with IPF--an observation that we suspect is due to an increased rate of mortal acute exacerbations in patients with IPF.

The Antithrombotic Therapy and the Prevention of Thrombosis, 9th Edition: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines (AT9) represent trustworthy international guidelines for antithrombotic treatment and thromboprophylaxis. We describe major changes to the format and content resulting from applying new strategies for guideline adaptation and dissemination. ⋯ New strategies for adapting, updating, and disseminating trustworthy guidelines proved feasible and will provide Norwegian health-care professionals and patients with up-to-date guidance tailored to national circumstances.

The magnitude and implication of variation in end-of-life decision-making among ICUs in the United States is unknown. ⋯ Although patient factors explain much of the variability in DFLST practices, significant effects of ICU culture and practice influence end-of-life decision-making. The observation that an ICU's risk-adjusted propensity to withdraw life support is directly associated with its standardized mortality ratio suggests problems with using the latter as a quality measure.

Indwelling pleural catheters (IPCs) are commonly used to manage malignant effusions. Tumor spread along the catheter tract remains a clinical concern for which limited data exist. We report the largest series of IPC-related catheter tract metastases (CTMs) to date, to our knowledge. ⋯ IPC-related CTM is uncommon but can complicate both mesothelioma and metastatic carcinomas. The duration of interval after IPC insertion is the key risk factor identified for development of CTM. Symptoms are generally mild and respond well to radiotherapy, which can be administered safely without removal of the catheter.

Adaptation of guidelines for use at the national or local level can facilitate their implementation. We developed and evaluated an adaptation process in adherence with standards for trustworthy guidelines and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, aiming for efficiency and transparency. This article is the first in a series describing our adaptation of Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines for a Norwegian setting. ⋯ This case study demonstrates the feasibility of a novel guideline adaptation process. Replication is needed to further validate the usefulness of the process in increasing the organizational and methodologic efficiency of guideline adaptation.
