RATIONALE ICU-acquired paresis (ICUAP) is common in survivors of critical illness. There is significant associated morbidity, including prolonged time on the ventilator and longer hospital stay. However, it is unclear whether ICUAP is independently associated with mortality, as sicker patients are more prone and existing studies have not adjusted for this.(More)
STUDY OBJECTIVES Pneumothorax is a common complication of lymphangioleiomyomatosis (LAM), and the optimal approach to its treatment and prevention is unknown. Chemical or surgical pleurodesis are often required to prevent recurrence. However, their efficacy in LAM is unclear, and whether they contribute to perioperative complications during lung(More)
Multiple and paradoxical effects of airway smooth muscle (ASM) 7-transmembrane-spanning receptors activated during asthma, or by treatment with bronchodilators such as beta(2)-adrenergic receptor (beta(2)AR) agonists, indicate extensive receptor crosstalk. We examined the signaling of the prostanoid-EP(1) receptor, since its endogenous agonist prostaglandin(More)
beta-adrenergic receptors (betaARs) relax airway smooth muscle and bronchodilate, but chronic beta-agonist treatment in asthma causes increased sensitivity to airway constriction (hyperreactivity) and is associated with exacerbations. This paradox was explored using mice with ablated betaAR genes (betaAR-/-) and transgenic mice overexpressing airway smooth(More)
Pleural disease is a common complication of lymphangioleiomyomatosis (LAM). The incidence and recurrence rates of secondary spontaneous pneumothorax in LAM are the highest among chronic pulmonary disorders. Most patients have at least one pneumothorax before LAM is diagnosed, and pneumothorax is often the sentinel event that leads to the diagnosis. Although(More)
OBJECTIVE Information in critical care environments is distributed across multiple sources, such as paper charts, electronic records, and support personnel. For decision-making tasks, physicians have to seek, gather, filter and organize information from various sources in a timely manner. The objective of this research is to characterize the nature of(More)
OBJECTIVE Withdrawal or withholding of life-sustaining therapies precedes most deaths in the modern ICU. As goals of care for critically ill patients change from curative to palliative, this transition often occurs abruptly, but a slower more staggered approach may also be used. One such approach is "no escalation of care", often the first step in this(More)
STUDY OBJECTIVES The American College of Chest Physicians Delphi Consensus Statement on management of spontaneous pneumothorax recommended pleurodesis after the first secondary spontaneous pneumothorax to prevent recurrence, and evaluation of patients' perspectives regarding pneumothorax treatment was identified as a future research priority. Patients with(More)
Healthcare waste-the inappropriate use of healthcare resources that provides no benefit to patients yet contributes to cost and even harm-is a potentially significant contributor to high healthcare costs. This project aimed to apply a new locally modified Institute for Healthcare Improvement (IHI)-developed waste identification tool to measure the(More)
