The use of technology-enhanced coursework by rehabilitation counselor educators has increased dramatically over the last decade. In many cases, educators are using new technologies to support traditional modes of teaching and learning. Research conducted in technology-enhanced coursework has primarily focused on the cognitive and psychomotor domains of learning. However, little research exists regarding the development of students' affective knowledge (i.e., feelings, values, attitudes). In this paper, Bloom's (1956) taxonomy of learning domains is used as a paradigm to examine the strengths, limitations, and unknowns of technology-enhanced training as compared to traditional education settings. A review of empirical evidence and future research directions are discussed to facilitate greater discussion among rehabilitation counselor educators. [ABSTRACT FROM AUTHOR]

Objective: To assess the concurrent validity of three screening tests for focal cognitive impairments after stroke.Design: Comparison of results from the screening tests with those from a more comprehensive neuropsychological battery.Setting: Stroke rehabilitation wards of a general hospital and a rehabilitation hospital.Subjects: Forty-nine stroke patients (25-91 years, 35% women).Measures: Screening tests were the Cognistat, the Screening Instrument for Neuropsychological Impairments in Stroke (SINS) and the Clock Drawing Test. Health professionals, blind to the results of the reference method, did the screening. Reference method was a neuropsychological assessment based on the Norwegian Basic Neuropsychological Assessment, classifying the patients as ;impaired' or ;not impaired' within the following cognitive domains: language, visuospatial function, attention and neglect, apraxia, speed in unaffected arm, and memory.Results: The best sensitivity (95% confidence interval) was achieved for language problems by Cognistat, naming (80%, 44-98); for visuospatial dysfunction, attention deficits and reduced speed, all by SINS visuocognitive (82%, 60-95, 72%, 39-94, and 78%, 56-93, respectively); and for memory problems by Cognistat memory (69%, 52-87). The data were insufficient to assess any subtest for apraxia. Sensitivity in detecting deficits in any domain was 82% (71-94) for the Cognistat composite score, 71% (57-85) for the SINS composite score, and 63% (49-78) for the most sensitive score of the Clock Drawing Test.Conclusion: The Cognistat and the SINS may be used as screening instruments for cognitive deficits after stroke, but cannot replace a neuropsychological assessment. The Clock Drawing Test added little to the detection of cognitive deficits. [ABSTRACT FROM AUTHOR]

Use of microencapsulation technology in combination with absorption enhancers eliminated epithelium irritation and necrosis commonly associated with nasal delivery of cytotoxic therapeutic agents. Phenothiazines, such as ethopropazine (ETZ), promethazine, trimeprazine and propiomazine have been used for the treatment of allergenic conditions, motion sickness, nausea, Parkinson's disease, Prion disease and as a sedative for psychiatric disorders. The enantiomers of commercially available racemic phenothiazines were isolated and purified using classical diastereomeric salt techniques. The racemate and the enantiomers of ETZ were tested in vitro for their cellular toxicity using lung fibroblast cells. Each enantiomer was shown to be cytotoxic at concentrations greater than 10 -5 molar. The ETZ enantiomers were encapsulated using spinning disk atomization to prepare a nasal delivery dosage form that does not produce an irritation response. Release rates for the ETZ microcapsules were determined in vitro and an animal study was conducted to determine the irritation response of rat nasal mucosa when dosed with encapsulated vs. non-encapsulated ETZ.

Optimal metabolic control to minimize long-term complications is a major treatment goal for adolescents with diabetes mellitus. Reaching this goal is extremely challenging in this population due to unique physiological changes and psychosocial variables that affect metabolic control. Continuous subcutaneous insulin infusion (CSII) may be an excellent treatment alternative for selected adolescents to help overcome some of these challenges. CSII allows for minute insulin changes at variable times throughout the day, providing greater lifestyle flexibility. The purpose of this paper is to review the use of insulin pump therapy in adolescents. Specific strategies regarding screening, initiation, and maintenance of this therapy are described, and case examples are used for illustration. Implications for nursing practice and diabetes education are discussed. [ABSTRACT FROM AUTHOR]

Nasal secretions, faecal samples and buffy coats were obtained from 102 cattle from a North Dakota dairy herd with a history of calf scours. Treated buffy coats, faecal samples and nasal secretions were inoculated into tetrathionate broth (TB), incubated at 37°C overnight, and plated onto brilliant green agar medium with novobiocin (BGAN). The TB was left at room temperature for 5 days and then used to inoculate fresh TB. The fresh TB was incubated at 37°C over night and plated onto BGAN medium. All the plates were incubated at 37°C over night and observed for Salmonella-like growth. Suspect colonies were further tested and Salmonella isolates were serotyped by the National Veterinary Services laboratory. Twenty-two of the 36 calves sampled harboured S. typhimurium in their faeces, but no samples from cows were positive. No Salmonella were isolated from the buffy coats, but 4 calves were shown to have Salmonella in their nasal secretions. Extended enrichment of the faecal cultures in TB resulted in a significant increase in Salmonella isolations, although 2 samples were positive following the initial enrichment period and not after secondary enrichment. The typical Salmonella isolate detected from this herd contained a transmissible R-plasmid encoding resistance to tetracycline, kanamycin, sulphisoxazole and ampicillin. This study confirmed that delayed secondary enrichment in TB is superior to primary enrichment for detection of Salmonella from cattle. [ABSTRACT FROM AUTHOR]
