Tracking autoionizing-wave-packet dynamics at the 1-fs temporal scale.

We present time-resolved studies and Fourier transform spectroscopy of inner-shell excited states undergoing Auger decay and doubly excited autoionizing states, utilizing coherent extreme-ultraviolet (XUV) radiation continua. Series of states spanning a range of ∼4 eV are excited simultaneously. An XUV probe pulse tracks the oscillatory and decaying evolution of the formed wave packet. The Fourier transform of the measured trace reproduces the spectrum of the series. The present work paves the way for ultrabroadband XUV spectroscopy and studies of ultrafast dynamics in all states of matter.

Community-oriented primary care: critical assessment and implications for resident education.

BACKGROUND: Community-oriented primary care (COPC) is a systematic approach to health care based on principles derived from epidemiology, primary care, preventive medicine, and health promotion that has been shown to have positive health benefits for communities in the United States and worldwide. METHODS: MEDLINE was searched using the key phrase "community-oriented primary care." Other sources of information were books and other documents. RESULTS AND CONCLUSIONS: Because of lack of predictable reimbursement for COPC services and difficulties encountered incorporating COPC in medical and residency curricula, widespread application of COPC has not occurred. Recent trends in public health initiatives, managed health care, and information technology provide an environment ripe for application of COPC in medical practice. Also, recent recommendations made by the Strategic Planning Working Group of the Academic Family Medicine Organizations and the Association of Family Practice Residency Directors regarding specific community competencies for residency training have direct bearing on COPC and family medicine educators. These trends and recommendations, properly configured, will produce a medical training and practice environment conducive to COPC.

Community-oriented primary care: historical perspective.

BACKGROUND: Community-oriented primary care (COPC) is a systematic approach to health care based upon principles derived from epidemiology, primary care, preventive medicine, and health promotion. We describe the development of COPC from an historical perspective. A critical assessment of current trends and implication for physician education and practice of COPC will be discussed in a companion article in the next issue of The Journal. METHODS: MEDLINE was searched using the key phrase "community-oriented primary care" Other sources of information included books and other documents. RESULTS AND CONCLUSIONS: In the 1950s, Sydney Kark showed dramatic positive changes in the health status of the population of Pholela, South Africa, using this approach. Similar approaches showed positive change in the health status of poor and underserved populations in the United States. The results were so impressive that the Institute of Medicine recommended widespread application of COPC in the United States. Successful COPC practices, however, have historically required considerable external funding from private and government sources. Thus, controversy about the feasibility of implementation of COPC in mainstream primary care practices developed. Schools of medicine and the discipline of family medicine have struggled to implement effective training in COPC within traditional medical school and residency structures. Yet, the societal need for recognition of and intervention in community health problems and coordination of community health resources continues.

Health status, staffing, and medicaid reimbursement in nursing homes: 1985 to 1995.

CONTEXT: Policy changes implemented by Medicaid and Medicare in the early 1980s resulted in a functionally more dependent nursing home population. OBJECTIVES: This paper contends that (1) staffing in nursing homes has become more efficient; (2) nursing home residents are functionally more dependent;(3) Medicaid per diem reimbursement is inadequate. DATA SOURCES: Staffing data came from the National Nursing Home Facility Survey conducted by the National Center for Health Statistics (NCHS) in 1985 and 1995. Functional dependency data, defined as assistance with any of six Activities of Daily Living (ADLs), came from the NCHS National Nursing Home Current Resident Surveys in 1985 and 1995. Reimbursement rates came from the State Medicaid Reimbursement Surveys conducted by the University of California at San Francisco to which the Consumer Price Index, Hospital and Related Services Item was applied. DATA SYNTHESIS: Administration decreased by 4.4 full-time equivalents (FTEs) (80.0%) per 100 beds, whereas patient care increased by 8.2 FTEs (18.9%). Residents requiring assistance with four or more ADLs increased by 9.9%, and the mean number of ADLs per patient increased from 3.9 to 4.3. Applying the Consumer Price Index to the 1984 reimbursement rate indicated an annual deficit of 5526.00 dollars for each Medicaid patient by 1995. CONCLUSIONS: This research strongly supports its contentions but fails to demonstrate them conclusively. The data indicate that long-term care facilities have reallocated staffing to accommodate the requirements of more functionally dependent residents and that Medicaid reimbursement has failed to maintain its initial purchasing power.

Efficacy of transdermal clonidine for headache prophylaxis and reduction of narcotic use in migraine patients. A randomized crossover trial.

Thirty patients completed a double-blind, randomized crossover study utilizing transdermal clonidine and an identical-appearing placebo. Crossover occurred at 6 weeks, with a total study time of 12 weeks. Subjects were asked to record daily in a special diary (1) the presence or absence of headache, (2) duration of headache, (3) severity of headache, and (4) use of pain medication for headache relief. The severity of the headaches was rated from 1 (very mild) to 5 (very severe). Although the subjects reported a decrease in frequency, duration, and intensity of headaches while using the medicated patch, these differences did not reach statistical significance. Nineteen patients subjectively preferred the medicated patch, while five preferred the placebo (P less than .01). During use of the medicated patch, a significant reduction (P = .039) occurred in use of class II narcotics. Three doses of these substances were used by the patients when treated with clonidine, while 34 doses were taken during placebo use. These findings suggest that clonidine might have a role in reduction of parenteral narcotic use in acute pain syndromes.
