Early sexual initiation and subsequent sex-related risks among urban minority youth: the reach for health study

Autor: L, O'Donnell, C R, O'Donnell, A, Stueve

Publikováno v: Family planning perspectives. 33(6)

Since the 1980s, the age at which U.S. teenagers, especially minority youth, begin having sex has decreased. There is limited information on the relationship between early sexual initiation and subsequent risky sexual behaviors.A sample of 1,287 urba

Publikováno v: The American psychologist. 50(9)

Nationally, homicide and suicide are the 2nd and 3rd leading causes of death among children and youth under the age of 21. Sixteen to 19-year-olds now have the highest rate of handgun victimization among all age groups. The firearm suicide rate for W

Predictors of condom acquisition after an STD clinic visit

Autor: L, O'Donnell, A, San Doval, R, Duran, C R, O'Donnell

Publikováno v: Family planning perspectives. 27(1)

Data from a survey of 691 men and women who made patient visits to an inner-city, sexually transmitted disease (STD) clinic and were given coupons to redeem for condoms at a neighborhood pharmacy show that only 22% of the sample did so. Gender, ethni

Indications for preoperative pulmonary function testing

Autor: J D, Zibrak, C R, O'Donnell

Publikováno v: Clinics in chest medicine. 14(2)

Atelectasis, hypoxemia, pneumonia, and respiratory failure are pulmonary complications that can follow surgical procedures. This article discusses controversies surrounding the use of preoperative pulmonary function testing to identify high-risk surg

The flow-ratio index. An approach for measuring the influence of age and cigarette smoking on maximum expiratory flow-volume curve configuration

Autor: C R, O'Donnell, R M, Rose

Publikováno v: Chest. 98(3)

A forced expiratory flow ratio, derived from the average slope of the maximum expiratory flow-volume (MEFV) curve over a specified volume interval, was examined in healthy asymptomatic cigarette smokers and nonsmokers. This index was developed to hav

In vivo estimation of tracheal distensibility and hysteresis in normal adults

Autor: R. G. Castile, Jeffrey J. Fredberg, M. E. Wohl, C. R. O'Donnell, V. Hoffstein, Denise J. Strieder, G. M. Glass

Publikováno v: Journal of Applied Physiology. 63:2482-2489

We used the acoustic reflection technique to measure the cross-sectional area of tracheal and bronchial airway segments of eight healthy adults. We measured airway area during a slow continuous expiration from total lung capacity (TLC) to residual vo

Changes in flow-volume curve configuration with bronchoconstriction and bronchodilation

Autor: Jere Mead, C. R. O'Donnell, R. G. Castile

Publikováno v: Journal of applied physiology (Bethesda, Md. : 1985). 61(6)

Changes in the configuration of maximum expiratory flow-volume (MEFV) curves following mild degrees of bronchodilation or bronchoconstriction were studied in five normal and five asthmatic subjects. In a volume-displacement plethysmograph, MEFV curve
