Persons with congestive heart failure may be susceptible to ambient air pollution. The authors evaluated the association between exposure to particulate matter with an aerodynamic diameter of <2.5 microm (PM2.5) and onset of symptom exacerbation leading to hospital admission in Baltimore, Maryland. They used a case-crossover design for 135 case events(More)
BACKGROUND Lymphovascular invasion (LVI) is considered a high-risk pathologic feature in resected non-small cell carcinoma (NSCLC). The ability to stratify stage I patients into risk groups may permit refinement of adjuvant treatment recommendations. We performed a systematic review and meta-analysis to evaluate whether the presence of LVI is associated(More)
BACKGROUND Current guidelines consider the absence of a dependable social support system as an absolute contraindication to lung transplantation, yet there are varying degrees of social support among those selected for transplantation. We sought to characterize the relationship between a patient's self-reported primary caregiver and long-term outcomes after(More)
Little is known of the needs of family members who provide home care to persons receiving ventilatory support (VS). In a structured interview of 44 care givers of 29 persons receiving VS, finances, provisions for emergencies, information, family relationships, and continuity of care were ranked as the most important needs. Needs for support services were(More)
We describe the application of complexity estimation and the surrogate data method to identify deterministic dynamics in simulated gravitational wave (GW) data contaminated with white and coloured noises. The surrogate method uses algorithmic complexity as a discriminating statistic to decide if noisy data contain a statistically significant level of(More)
BACKGROUND Hospital readmissions are costly and have become a focus for quality improvement. We aimed to determine risk factors, rate, and outcomes of readmissions within the first year after lung transplantation and the potential impact on patient survival. METHODS A retrospective cohort study of all lung transplant recipients ≥18 years old who had(More)
