Reliability of breath-alcohol analysis in individuals with gastroesophageal reflux disease.

Gastroesophageal reflux disease (GERD) is widespread in the population among all age groups and in both sexes. The reliability of breath alcohol analysis in subjects suffering from GERD is unknown. We investigated the relationship between breath-alcohol concentration (BrAC) and blood-alcohol concentration (BAC) in 5 male and 5 female subjects all suffering from severe gastroesophageal reflux disease and scheduled for antireflux surgery. Each subject served in two experiments in random order about 1-2 weeks apart. Both times they drank the same dose of ethanol (approximately 0.3 g/kg) as either beer, white wine, or vodka mixed with orange juice before venous blood and end-expired breath samples were obtained at 5-10 min intervals for 4 h. An attempt was made to provoke gastroesophageal reflux in one of the drinking experiments by applying an abdominal compression belt. Blood-ethanol concentration was determined by headspace gas chromatography and breath-ethanol was measured with an electrochemical instrument (Alcolmeter SD-400) or a quantitative infrared analyzer (Data-Master). During the absorption of alcohol, which occurred during the first 90 min after the start of drinking, BrAC (mg/210 L) tended to be the same or higher than venous BAC (mg/dL). In the post-peak phase, the BAC always exceeded BrAC. Four of the 10 subjects definitely experienced gastric reflux during the study although this did not result in widely deviant BrAC readings compared with BAC when sampling occurred at 5-min intervals. We conclude that the risk of alcohol erupting from the stomach into the mouth owing to gastric reflux and falsely increasing the result of an evidential breath-alcohol test is highly improbable.     

Environmental Commitment among the States: Integrating Alternative Approaches to State Environmental Policy

This article examines variation in state commitment to protectingthe natural environment. We contribute to theoretical and empiricalresearch in this area in two primary ways. First, our dependentvariable consists of a general measure of state commitment tothe environment. Second, we develop a causal model that integratessix major explanatory approaches to state environmental policy.Our results show that stales with liberal public opinion, strongenvironmental interest groups, liberal legislatures, and professionalizedlegislatures are the most committed to environmental protection.States' manufacturing interests and economic resources playa relatively minor role, and slates' environmental conditionsand the influence of the federal government play virtually norole in explaining variation in general state commitment toenvironmental protection.

Teenage pregnancy and neonatal behavior: Effects in Puerto Rico and Florida

The purpose of this study was to examine the relationship between neonatal behavior and prenatal and perinatal risk factors in infants of teenage and older mothers in Puerto Rico and Mainland United States. The sample included approximately 300 newborn infants;half were examined in Puerto Rico, the other half in Florida, using the Brazelton Neonatal Behavioral Assessment Scale. Comparisons by maternal age and the number of obstetrical complications showed that for the Puerto Rican group, infants with fewer obstetrical complications were better able to regulate their crying and active states. Infants of teenage mothers with fewer complications had a higher level of arousal than infants of older mothers with fewer complications. Infant behavior in the Mainland sample did not vary by maternal age or complications. Multiple regression analysis indicated that the combination of biomedical variables significantly predicted neonatal behavior in both cultures. Mother's age was not separately correlated with neonatal behavior, but was repeatedly combined with other variables in the significant regressions. The findings suggest that infants of teenage mothers may differ from infants of older mothers, particularly in the organization of state behavior, and that the effects of maternal age on neonatal behavior are increased in the presence of biological outcome factors.This article is based on a final report to the NICHD Center for Population Research, Contract N01-HD-7283.Received Ph.D. from Michigan State University.

Components of loneliness during adolescence

Predictors of adolescent loneliness were investigated in two samples of high school students (n=92)and college undergraduates (n=192).Results were similar across samples. Among the high school sample loneliness was significantly predicted by a combination of alienation, a lack of social facility and acceptance, inferiority feelings, negative school attitudes, and a lack of social integration. Among college students loneliness was negatively related to social facility, regularity, approval, and involvement and positively related to alienation, parental disinterest, negative school attitudes, and inferiority feelings.Research interests include loneliness and self-concept.Received Ph.D. in social psychology from Oklahoma State University. Research interests include loneliness and friendships.
