Resource Utilization of Adults Admitted to a Large Urban Hospital With Community-Acquired Pneumonia Caused by Streptococcus pneumoniae: Data Collection
Patients were excluded if their total hospitalization was < 2 days, if they had impaired immune function (ie, AIDS, HIV, leukocyte count < 1,000/^L), known or suspected tuberculosis, known or suspected Pneumocystis ji-roveci, or concomitant pneumonia or other infection at baseline caused by viruses, fungi, or other bacteria except intracellular pathogens (Mycoplasma pneumoniae, Chlamydophila pneumoniae, […]
Resource Utilization of Adults Admitted to a Large Urban Hospital With Community-Acquired Pneumonia Caused by Streptococcus pneumoniae: Study Design
All can result in increased hospital length of stay, thereby significantly escalating costs. However, few cost-of-illness studies have attempted to evaluate the economic impact of penicillin susceptibility in patients with CAP caused by S pneumoniae. The primary objective of this study was to determine resource utilization and costs associated with the in-hospital treatment of CAP […]
Resource Utilization of Adults Admitted to a Large Urban Hospital With Community-Acquired Pneumonia Caused by Streptococcus pneumoniae
Pneumonia is the sixth-leading cause of death in the United States and the number-one cause of death from an infectious disease. The subset of patients who acquire pneumonia while not residing in a hospital or long-term care facility for at least 2 weeks before the onset of symptoms are defined as having community-acquired pneumonia (CAP). […]
Competition for Intrathoracic Space Reduces Lung Capacity in Patients With Chronic Heart Failure: Conclusion
This muscle fiber atrophy is associated with significant reductions in tissue force generation, thus limiting resting tonality and potentially contributing the upward crescent shape of the diaphragm. Another potential contributor to the increased diaphragm volume includes ascites. Mutoh and col-leagues have shown, using a piglet model, a 40% reduction in TLC as a result of […]
Competition for Intrathoracic Space Reduces Lung Capacity in Patients With Chronic Heart Failure: Discussion
These authors also suggest that, due to the increase in cardiac size, diffusion capacity of the lung suffers adversely, primarily as a consequence of a reduction in membrane diffusion as opposed to pulmonary capillary blood volume. Although moderate but significant correlations were observed between the cardiothoracic index and various components of pulmonary function, these findings […]
Competition for Intrathoracic Space Reduces Lung Capacity in Patients With Chronic Heart Failure: Results
The relationship between NYHA class and absolute lung volume and percentage of TTCV that is taken up by the lung is shown in Figure 3, top, A, and bottom, B, respectively. These data suggest a clear relationship between increasing NYHA class and elevated cardiac volume and reduction in lung volume. Figure 4 demonstrates the close […]
Competition for Intrathoracic Space Reduces Lung Capacity in Patients With Chronic Heart Failure: Statistical Analysis
Statistical analysis and graphic presentation were accomplished using statistical software (Prism version 4.0; Graphpad; San Diego, CA). One-way analysis of variance was used to test for differences in means among the groups, and unpaired t test was used to compare the means of the participant characteristics and radiographic variables between the control and chronic heart […]
