Outcomes after withholding anticoagulation from patients with suspected acute pulmonary embolism and negative computed tomographic findings: a cohort study.
To determine the outcome of withholding anticoagulation from patients with suspected acute pulmonary embolism in whom computed tomographic (CT) findings are interpreted as negative for pulmonary embolism. ⋯ The incidence of (1) overall deep venous thrombosis or pulmonary embolism or (2) fatal pulmonary embolism among patients with suspected acute pulmonary embolism, negative CT results, and no other evidence of venous thromboembolism is low. Withholding anticoagulation in these patients appears to be safe.

Comparative StudyCost-minimization analysis of alternative diagnostic approaches in a modeled patient with non-small cell lung cancer and subcarinal lymphadenopathy.
To evaluate the costs of alternative diagnostic evaluations of enlarged subcarinal lymph nodes (SLNs) in modeled patients with non-small cell lung cancer (NSCLC). ⋯ Which testing strategy is least costly for SLN evaluation in a modeled patient with NSCLC may be determined by the pretest probability of nodal metastases. Use of EUS FNA biopsy minimizes the cost of diagnostic evaluation in most cases.

Self-reported weight, weight goals, and weight control strategies of a midwestern population.
To elicit from individuals in a population their current weight and height, weight goals, and weight control strategies to aid in design of effective interventions to prevent and treat obesity. ⋯ The prevalence of overweight and obesity in the population and the underutilization of combining both restricting energy intake and exercising at least 150 minutes per week for weight control is high. Like the majority of people in the United States, the majority of people in Olmsted County desire to control their weight. The community has responded with plans to help residents meet their goals, although efficacy and outcomes remain to be determined.

Surgical pathology of carcinoid heart disease: a study of 139 valves from 75 patients spanning 20 years.
To quantitate the pathologic features of carcinoid plaques in a relatively large number of surgical specimens from a single institution. ⋯ Among patients undergoing valvular surgery for carcinoid heart disease, tricuspid and pulmonary valves represented 92% of the excised valves (128/ 139). Although numerous cellular and extracellular features were common to the carcinoid plaques, variability in their relative expression produced appreciable differences in the histologic appearance among the plaques.
