Abstract
Individuals with cognitive disabilities have challenges with personal navigation and wayfinding, especially when traveling on public transportation. The purpose of this case study is to describe the structure and implementation of the Personal Navigation for Individuals with Disabilities (PNID) education and training program, which is based on a socio-technical architecture for individuals with cognitive disabilities within a fixed-route public bus system. A case study methodology was used to describe preliminary findings of the skills, attributes, and experiences of three individuals with cognitive disabilities as it relates to transportation on fixed-route bus systems in a midsized urban setting. The three individuals completed five training activities: safety, public bus, smartphone, WayFinder App, and fixed-route bus system. The case study provided a preliminary mixed-methods overview of training travelers with cognitive disabilities to use the WayFinder system while accessing fixed-route public bus system. The insights and strategies identified through the case study demonstrate the potential opportunities for development, implementation, and sustainability of the PNID program in other midsized urban settings. The PNID program (i.e. AT service delivery process), in combination with the WayFinder system (i.e. assistive technology), has the potential to meet the unique needs of individuals with cognitive disabilities when accessing public transportation.

Abstract
OBJECTIVE Cyclooxygenase inhibitors are effective tocolytic agents, but significant adverse effects limit their use. We hypothesized that selective inhibitors of the isozyme cyclooxygenase 2 would effectively diminish labor-associated prostaglandin production. STUDY DESIGN We analyzed cyclooxygenase type 1 and 2 expression in amnion, chorion, decidua, and myometrium from laboring or nonlaboring women and tested the efficacy of selective cyclooxygenase 2 inhibition in diminishing prostaglandin production. RESULTS The expression of cyclooxygenase 2 in amnion from women in labor, either preterm or at term, was significantly higher than in amnion before labor. In contrast, cyclooxygenase 1 expression was unchanged by labor. The enhanced expression of amniotic cyclooxygenase 2 was associated with increased prostaglandin E(2) levels in laboring women. Amniotic prostaglandin E(2) production was effectively diminished by the selective cyclooxygenase 2 inhibitors SC-236 and NS-398 but not by the cyclooxygenase 1 inhibitor SC-560. CONCLUSION Selective inhibitors of cyclooxygenase 2 are effective in diminishing prostaglandin production in vitro and may be useful in prevention of preterm deliveries.

Abstract
Administration of alfentanil followed by propofol intravenously (IV) without neuromuscular blockade for induction of anesthesia provides adequate conditions for tracheal intubation. Other hypnotic drugs have not been thoroughly investigated in this regard. Accordingly, 140 ASA physical status I and II premedicated outpatients were randomly assigned to one of seven groups (n = 20/group). Patients in Groups I-VI received alfentanil 40 microg/kg followed by etomidate 0.3 mg/kg, propofol 2 mg/kg, or thiopental 4 mg/kg. One half of these patients (Groups II, IV, VI) also received lidocaine 1 mg/kg IV prior to the administration of the above drugs. Patients in group VII received d-tubocurarine 3 mg followed by thiopental 4 mg/kg and succinylcholine 1 mg/kg. Ninety seconds after induction, laryngoscopy and endotracheal intubation were attempted and graded. Patients in Group V (alfentanil/thiopental) were significantly (P < 0.05) more likely to have a clinically unacceptable response to intubation (55%) (e.g., vigorous coughing, purposeful movement, or requirement for succinylcholine to complete intubation) compared with patients who received propofol (35%) or etomidate (20%). Alfentanil/etomidate yielded intubation conditions comparable to those achieved with alfentanil/propofol and d-tubocurarine/thiopental/succinylcholine. Lidocaine appeared to improve intubating conditions, although this improvement did not reach statistical significance. The results suggest that healthy, premedicated patients with favorable airway anatomy who have received alfentanil 40 microg/kg can be reliably tracheally intubated 90 s after administration of propofol 2 mg/kg or etomidate 0.3 mg/kg.

Abstract
This study investigated the relationship between reading comprehension and oral storytelling abilities. Thirty-one Latino junior high school students with learning handicaps were selected as subjects based on learning handicapped designation, home language, and language proficiency status. Reading comprehension was measured by the Reading Comprehension subtest of the Peabody Individual Achievement Test. Storytelling was measured by (a) the Oral Production subtest of the Language Assessment Scales using the standard scoring protocol and (b) a story structure analysis. A comparison of the standard scoring protocol and reading comprehension revealed no relationship, while the comparison of the story structure analysis and reading comprehension revealed a significant correlation. The implications of these results for language assessment of bilingual students are discussed.

Abstract
Numerous techniques have been used in attempts to find a reliable and efficient screening method for determining auditory function in the newborn. The brainstem auditory evoked potential (BAEP) is the latest method advocated for that purpose. The BAEP was evaluated as a hearing screening test in 168 high-risk newborns between 35 and 45 weeks of conceptual age. Follow-up data were obtained after 1 year (mean 17.3 months) on 134 of the infants (80%). Normal hearing was defined as a reproducible response in both ears to a 25 dB normal hearing level (nHL) click stimulus; 21 infants (12.5%) failed the initial screening test. Follow-up on 19/21 infants revealed 18 infants with normal hearing and one infant with an 80 dB nHL bilateral hearing loss substantiated. One infant with an abnormal screening test died before retesting, and the other infant was lost to follow-up but had only a unilaterally abnormal BAEP. None of the infants with a normal BAEP screening study had evidence of hearing loss on retesting. Sensitivity of the BAEP was 100%, specificity was 86%, predictive value of a positive test was 5.26%, and the predictive value of a negative test was 100%. The incidence of significant hearing loss in our population was between 0.75% (1/134 infants) confirmed, and 2.24% (3/134 infants) including infants who failed screening but were lost to follow-up. The BAEP is a sensitive procedure for the early identification of hearing-impaired newborns. However, the yield of significant hearing abnormalities was less than predicted in other studies using BAEP for newborn hearing screening.

Abstract
Brainstem stroke syndromes are primarily determined by clinical criteria. There are few diagnostic procedures which are of benefit for the evaluation of brainstem ischemic events. Brainstem auditory evoked responses (BAERs) are a new electrophysiologic technique for assessing brainstem function. To evaluate the use of BAERs in patients with brainstem ischemic events, 35 individuals with recent brainstem strokes, selected by strict clinical criteria, were evaluated with BAERs. The initial BAER was abnormal in 22 of 35 patients (63%). When the clinical course and site of the lesion are correlated with the BAER results, several trends emerge. An unstable course, characterized by progression or remission and relapse, was present in 19/35 (54%) of patients, and 15/19 (79%) of these individuals had an initially abnormal BAER. The other 16 brainstem stroke patients with a stable clinical course had an initially abnormal BAER in 7 instances (44%). This difference is statistically significant at the p = 0.04 level. The principal sites of ischemia were mesencephalic in 11/35, pontine in 13/35, and medullary in 11/35. The association of an abnormal BAER with an unstable clinical course seemed independent of the site of the lesion, However, of the 9 deaths that occurred, all were in patients with mesencephalic or pontine lesions, and 8 of these individuals had an initially abnormal BAER. Abnormal BAERs in patients with brainstem ischemic lesions correlate with an unstable clinical course. Furthermore, individuals with pontomesencephalic infarction and abnormal BAERs have an especially poor prognosis. The BAER may be of prognostic value in the early evaluation of patients with brainstem ischemic strokes.

Abstract
Abnormalities of visual, brainstem auditory, and somatosensory evoked responses were demonstrated in two of seven individuals with vitamin B12 deficiency. The evoked response delays correlated directly with the degree of neurological dysfunction. Abnormalities were present in sensory systems without clinical evidence of involvement and were similar to those found in individuals with multiple sclerosis.
