Increased atmospheric CO2 may affect the physiological response of natural trees to drought. We examined radial growth rates developed from five western juniper chronologies to determine if post-drought growth responses have changed. Using prior year October to current year June precipitation from 1896-1998, we identified drought recovery years as having standardized scores (z-scores) > 0 and p...
We inventoried two 1-ha plots on opposing watersheds (WS2–WS-S, WS18–WS-N) three times (1983, 1989, 1998) over a 16-year period to contrast how differing precipitation (P) regimes affect tree mortality. From 1983 to 1989, annual precipitation averaged 16.5% less than the 64-year mean; from 1989 to 1998, it averaged 12.2% above the mean. In 1989 and 1998, standing crop biomass, aboveground net p...
OBJECTIVE For decades, kidney cancer patients in Denmark have had lower survival than patients in the other Scandinavian countries. Our aim was to study possible changes in survival of patients with kidney cancer after implementation of two national Danish cancer plans. STUDY DESIGN AND SETTING From 1998 through 2009 we included all patients (N = 2659) with an incident diagnosis of kidney can...
BACKGROUND Modern drug therapy accounts for a major share of health expenditure and challenges public provider resources. The objective of our study was to compare drug expenditure trends for ten major drug classes over 16 years at Maccabi Healthcare Services (MHS), the 2(nd) largest healthcare organization in Israel. METHODS A retrospective analysis of drug expenditure per HMO beneficiary be...
BACKGROUND We evaluated historical trends in the Staphylococcus aureus infection rate, economic burden, and mortality in US hospitals from 1998 through 2003. METHODS The Nationwide Inpatient Sample was used to assess trends over time of S. aureus infection during 1998-2003. Historical trends were determined for 5 strata of hospital stays, including all inpatient stays, surgical procedure stay...
OBJECTIVE The Zwolle Outpatient Diabetes project Integrating Available Care (ZODIAC) study was initiated in 1998 to investigate the effects of shared care for patients with type 2 diabetes mellitus (T2DM) in the Netherlands, and to reduce the number of diabetes-related complications. Benchmarking the performance of diabetes care was and is an important aspect of this study. We aimed to investig...
