Overview of proposed revisions to the superfund hazard ranking system.

The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 required the federal government to establish criteria for setting priorities among releases of hazardous substances, pollutants, and contaminants. The U.S. Environmental Protection Agency responded by developing the Hazard Ranking System (HRS), which is a scoring system used to establish the National Priorities List (NPL). The Superfund Amendments and Reauthorization Act of 1986 required EPA to amend the HRS so it will more accurately assess relative risks and take into account certain specific elements of risk. On December 23, 1988, EPA published in the Federal Register the proposed rule to revise the HRS. EPA expects to issue the final rule in 1990 after reviewing public comments. This paper describes the proposed revisions and summarizes major technical findings that support the revisions. As a result of the HRS revisions, there may be some changes in the types of sites that score high enough to be placed on the NPL. A projection of those changes is discussed.

In vivo distraction-coping in the treatment of test anxiety: a 1-year follow-up study.

Data obtained from 19 clinically test anxious students supported the efficacy of an 8-week treatment program that combined relaxation skill training, cognitive restructuring, and systematic desensitization for the reduction of test anxiety in a previous study by Thyer , Papsdorf , Himle , McCann , Caldwell, and Wickert (1981). Significant reductions in test, state, and trait anxiety, and increases in the rationality of personal belief systems were observed. Cognitive performance on an anagram solution task and behavioral performance on a test of manual dexterity also were improved posttreatment. In this present study, 12-month follow-up data on 14 (73.6%) of the original Ss are reported. The results indicate a maintenance of the significantly decreased levels of test anxiety and continued reductions in trait anxiety and irrationality . The significance of these findings is discussed.

Glycosylated haemoglobin and plasma glycoprotein assays by affinity chromatography.

A rapid chromatography method for separating glycosylated protein from non-glycosylated protein, using a boronate-agarose affinity medium which selectively binds the cis-diol groups of glycoproteins, was used to quantitate plasma glycoprotein as well as glycohaemoglobin. The results were found to be independent of: (1) temperature from 16.5 to 29.8 degrees C; (2) haemoglobin variants, and (3) aldimine glycoprotein adducts. Thus several of the common problems occurring in existing haemoglobin A1 assays are eliminated. There was a close correlation between glycohaemoglobin measured by affinity chromatography and haemoglobin A1 by cation-exchange (r = 0.959, n = 215). Specimens from 103 diabetic patients and 112 healthy volunteers were assayed. The following reference ranges were established: glycohaemoglobin 5.5-8.4%; glycosylated total protein 11.5-16.2%; glycoalbumin 11.6-19.5%.

In vivo distraction-coping in the treatment of test anxiety.

Two groups (N = 19) of clinically test anxious college students received a common core treatment program of cognitive behavior therapy, progressive muscular relaxation training, and thermal biofeedback assisted relaxation training. The experimental group received an additional treatment component that consisted of in vivo distraction-coping training designed to facilitate focusing attentional processes onto task relevant variables and away from external distractors and dysfunctional self-statements. The overall efficacy of the program was demonstrated with reductions in test, trait and state anxiety, and increases in the rationality of personal belief systems. Performance on an anagram solution task conducted under highly distracting conditions and evaluative interactions was improved significantly, as was motoric performance on a manual dexterity task. In vivo distraction-coping was not found to result in more efficacious treatment as measured by self-report and performance variables.

Cystic fibrosis, intravenous antibiotics, and home therapy.

The survival rate of patients with cystic fibrosis has improved considerably in the last 20 years. Although not all of the factors accounting for this change are understood, aggressive nutritional management and treatment of pulmonary exacerbations certainly play a role. Home intravenous (IV) antibiotic delivery for pulmonary exacerbation has proved to be as effective as hospital treatment and offers significant advantages to the patient and family. This article examines the microbiology of pulmonary infections in patients with cystic fibrosis, as well as antimicrobial therapy, methods of IV administration, home IV therapy, and the nurse practitioner's role in this home program in the future.

Educational programs in radiologic technology.

This article reports on a survey of educational programs in radiography, nuclear medicine, radiation therapy and sonography. The purpose of the survey was to help educators validate their individual program requirements by providing a profile of educational programs in each discipline. Survey results demonstrate similarities in program length, academic system, faculty teaching load and enrollment size. Major differences were found in clinical hour requirements and credit hour conversion.
