Bronchoscopy is often the initial diagnostic procedure performed in patients with pulmonary lesions suspicious for lung cancer. A bronchial genomic classifier was previously validated to identify patients at low risk for lung cancer after an inconclusive bronchoscopy. In this study, we evaluate the potential of the classifier to reduce invasive procedure utilization in patients with suspected lung cancer.
Urine output (UO) is a vital sign for critical ill patients but standards for monitoring and reporting vary widely between ICUs. Careful monitoring of UO could lead to earlier recognition of acute kidney injury (AKI) and better fluid management. We sought to determine if intensity of UO monitoring is associated with outcomes in patients with and without AKI.
We update recommendations on 12 topics that were in the 9th edition of these guidelines, and address 3 new topics.
In COPD, functional status is improved by pulmonary rehabilitation (PR) but requires specific facilities. Tai Chi, which combines psychological treatment and physical exercise and requires no special equipment, is widely practiced in China and is becoming increasingly popular in the rest of the world. We hypothesized that Tai Chi is equivalent (ie, difference less than ±4 St. George’s Respiratory Questionnaire [SGRQ] points) to PR.
The global burden of sepsis is estimated as 15 to 19 million cases annually with a mortality rate approaching 60% in low income countries.
Chest x-ray (CXR) is the test of choice for diagnosing pneumonia. Lung ultrasound (LUS) has been shown to be accurate for diagnosing pneumonia in children and may be an alternative to CXR. Our objective was to determine the feasibility and safety of substituting LUS for CXR when evaluating children with suspected pneumonia.
Lung nodules are a diagnostic challenge with an estimated yearly incidence of 1.6 million in the United States. This study evaluated the accuracy of an integrated proteomic classifier in identifying benign nodules in patients with a pretest probability of malignancy (pCA) ≤50%.
Chronic obstructive pulmonary disease (COPD) is often misdiagnosed and inappropriately treated in many patients. COPD is a distinct disease from adult-onset asthma; however, some patients with COPD may present with several forms of airway disease described as asthma-COPD overlap (ACO). Bronchodilators and inhaled corticosteroids (ICS) both have a place in standard maintenance treatment of COPD and asthma; however, recommendations for use differ widely. In patients with COPD, long-acting bronchodilators are effective initial monotherapy treatment, while ICS monotherapy is recommended as initial treatment in patients with asthma. Clinicians need to be confident in their diagnosis to ensure that correct treatment is given, as misguided treatment decisions can result in significantly increased safety risks for patients. This review highlights the differences in diagnosis and treatment between COPD, asthma, and ACO and discusses the data supporting guideline recommendations for use of bronchodilators in COPD treatment in contrast to asthma or ACO.
Over a quarter of the US population qualify as excessive alcohol consumers. Alcohol use impacts several lung diseases and heavy consumption has been associated with poor clinical outcomes. The fractional excretion of exhaled nitric oxide (FeNO) has clinical implications in multiple airway diseases. We hypothesized that excessive alcohol intake is associated with lower FeNO levels.
Problems with the use of inhalers by patients were noted shortly after the launch of the metered dose inhaler (MDI) and persist today. We aimed to assess the most common errors in inhaler use over the last 40 years in patients treated with MDI or dry powder inhalers (DPI).
