Daily mortality and fine and ultrafine particles in Erfurt, Germany part I: role of particle number and particle mass.
Increases in morbidity and mortality have been observed consistently and coherently in association with ambient air pollution. A number of studies on short-term effects have identified ambient particles as a major pollutant in urban air. This study, conducted in Erfurt, Germany, investigated the association of mortality not only with ambient particles but also with gaseous pollutants and indicators of sources. ⋯ Furthermore, the results for SO2 were inconsistent with those from earlier studies conducted in Erfurt. We conclude that both fine particles (represented by particle mass) and ultrafine particles (represented by particle number) showed independent effects on mortality at ambient concentrations. Comparable associations for gaseous pollutants were interpreted as artifacts of collinearity with particles from the same sources.

Comparative Study
Outcomes of older persons receiving rehabilitation for medical and surgical conditions compared with hip fracture and stroke.
Older persons with general medical and surgical conditions increasingly receive posthospital rehabilitation care in nursing homes and rehabilitation hospitals. This study describes the characteristics of such patients, contrasted with patients with traditional rehabilitation diagnoses of hip fracture and stroke. ⋯ Medical/surgical patients represent a unique rehabilitation population. They experienced greater premorbid functional disability, less acute decline, but greater mortality than patients with traditional rehabilitation diagnoses. Further study of this distinct rehabilitation population may help identify patients most likely to benefit from rehabilitation.

The Program of All-Inclusive Care for the Elderly (PACE) replicates the model of comprehensive, community-based geriatric care pioneered by On Lok, that enrolls frail older adults who meet states' criteria for nursing home care, and that uses interdisciplinary teams to assess the participants and to deliver care in appropriate settings. As managed care, PACE receives capitated payment from Medicare and Medicaid. Thus, PACE's fiscal incentives are thought to be aligned with the goals of optimizing health, function, and quality of life through the delivery of effective primary, preventive, restorative, supportive, and palliative care and through the avoidance of inappropriate and expensive hospital and nursing home utilization. ⋯ Overall, short-term hospital utilization among PACE participants is low in contrast with that for other older and disabled populations. Participant predictors of hospitalization in PACE are generally consistent with other studies in older clinical and community populations. Both utilization and risk vary considerably across PACE sites, independent of participant-level risk factors, hence suggesting that further investigation is required to study PACE's management of acute illness and hospitalization decisions. Critical to maintaining PACE's success is an understanding of the independent impact of the organization and the environment of health care on this management.

CONTENT/OBJECTIVES: No recent national studies have been published on age at death and causes of death for U.S. physicians, and previous studies have had sampling limitations. Physician morbidity and mortality are of interest for several reasons, including the fact that physicians' personal health habits may affect their patient counseling practices. ⋯ These findings should help to erase the myth of the unhealthy doctor. At least for men, mortality outcomes suggest that physicians make healthy personal choices.
