Abstract
This was the third annual validity study designed to assess the accuracy of the HESI Exam (E2) in predicting NCLEX success for graduating registered and practical nursing students. As in year I (N = 2,725) and year II (N = 3,752), in year III (N = 6,277), the E2 was highly predictive of NCLEX success for associate degree nursing, bachelor of science nursing, diploma, and practical nursing students. Unlike previous years, in year III, monitoring was not a significant factor in the predictive accuracy of the E2. NCLEX success of low-scoring E2 students, first examined in year II, was also examined in year III. As in year II, low-scoring E2 students were significantly more (P = .001) likely to fail the licensure examination than high-scoring E2 students. In year III, unlike year II, there was no significant difference in the pass rate of low-scoring E2 students who participated in a remediation program and those who did not. The authors recommended that a more definitive definition of remediation be used in future studies and that such studies focus on E2 implementation strategies and their relationship to NCLEX success.

Abstract
This article reports on young people with and without learning disabilities (LD) and substance use disorders (SUD). Participants were assessed for LD at ages 12 and 19 and for SUD and psychiatric disorders at age 19. Participants with LD at ages 12 and 19 were more likely to develop an SUD or a psychiatric disorder compared to participants without consistent LD. Participants with LD at age 19 were more likely to have a concurrent SUD or psychiatric disorder compared to those without LD at age 19, while participants with LD at age 12 showed only a trend toward increased rates of SUD at age 19 when compared to participants without LD at age 12. Participants with and without LD did not differ in substance use, consumption levels, or onset history. In a multivariate model, adolescent LD was associated with a three-fold increased risk for SUD after behavioral problems and family structure had entered the model. Although these results provide some support for the notion that adolescents with LD are at increased risk for SUD, LD also appears to confer a general risk for adverse outcomes.

Abstract
There has been an increasing interest in recent years in the evaluation of the neuronal and glial responses to ischemic insult. Some cytokines, including transforming growth factor-beta (TGF-beta), that are overexpressed after experimental stroke in rodents are thought to be implicated in the neuronal processes that lead to necrosis. Thus, such cytokines could predict tissue fate after stroke in humans, although data are currently sparse for gyrencephalic species. The current study addressed the expression pattern of TGF-beta1 in a nonhuman primate model of middle cerebral artery occlusion. Focal permanent ischemia was induced for 1 or 7 days in 6 baboons and the following investigations were undertaken: cerebral oxygen metabolism (CMRO2) positron emission tomography studies, magnetic resonance imaging, postmortem histology, and reverse transcription-polymerase chain reaction. The aim of the current study was to correlate the expression of TGF-beta1 to the underlying metabolic and histologic state of the threatened cerebral parenchyma. The authors evidenced increased TGF-beta1 mRNA levels (up to 25-fold) in those regions displaying a moderate (20% to 49%) reduction in CMRO2. The current findings suggest that the greatly enhanced expression of TGF-beta1 in the penumbral zones that surround tissue destined to infarction may represent a robust index of potentially salvageable brain. The current investigation, in the nonhuman primate, strengthens the authors' hypothesis, derived from rodent models, that TGF-beta1 may be involved in the physiopathology of human stroke.

Abstract
Rehabilitation experts have been addressing the problem of accommodating disabled workers in the workplace for many years. When these disabled workers return to work, accomplishing the tasks they performed prior to their disability can present a serious challenge. Meeting this challenge successfully requires that employers provide accommodations at the workplace so that the disabled workers can continue to contribute efficiently to the operation of the enterprise. Disabilities that are caused by amputations are quite critical. The severity of the injury in terms of loss of a limb and the costs associated with accommodations make this type of disability extremely significant. This paper deals with accommodating "permanent partial" and "permanent total disabilities" due to amputations. The paper is divided into two main parts. The first part focuses on the causes of amputations, types, and difficulties that an amputee faces in the work environment. In this part, an understanding of the amputee physiology has been developed. The second part of the paper addresses the various measures that employers may take in accommodating the amputees at the workplace. Design guidelines are provided to make the workplace suitable for the amputees.

Abstract
This study compares in vitro effects of exendin-4 and glucagon-like peptide (GLP)-1 on basal and glucose-stimulated insulin release from isolated rat islets and in vivo insulinotropic actions of exendin-4 and GLP-1 after an intravenous glucose challenge in rats. In static incubation of isolated islets, changing ambient glucose concentration from 3 mmol/L to 10 mmol/L stimulated insulin secretion 9.8 +/- 1.3-fold. The addition of exendin-4 or GLP-1 (1 nmol/L to 1 micromol/L) increased glucose-stimulated insulin secretion up to 5.8 +/- 1.6-fold and 3.3 +/- 1.0-fold, respectively, over basal rates (defined as no hormones added, 3 mmol/L glucose) and 19.6 +/- 2.3-fold and 15.0 +/- 3.1-fold at 10 mmol/L glucose. In dynamically perfused isolated islets exposed to 7.5 mmol/L glucose, insulin secretion increased 6.4 +/- 1.5-fold, and exendin-4 (20 nmol/L) or GLP-1 (20 nmol/L) increased this similarly by up to 13.5 +/- 2.8 and 12.7 +/- 3.9-fold,respectively. Anesthetized rats administered 5.7 mmol/kg intravenous glucose increased plasma insulin concentration 3.0-fold. Infusion of exendin-4 or GLP-1 increased this to a maximum of 7.6-fold and 5.3-fold, respectively. As with isolated islet studies, in vivo dose responses and concentration responses with exendin-4 and GLP-1 were bell-shaped. When insulinotropic effects were mapped onto the steady-state plasma concentrations associated with these infusion rates, both peptides exhibited bell-shaped concentration responses with peak insulinotropic effects occurring with plasma peptide concentrations of approximately 1 nmol/L in this model. In summary, exendin-4 and GLP-1 exhibited similar insulinotropic potencies (median effective dose [ED(50)]) when assessed on a concentration basis in in vitro and in vivo models, while exendin-4 exhibited greater efficacy (maximum response).

Abstract
Amylin (AMY) is a 37 amino acid peptide cosecreted with insulin (INS) by pancreatic beta-cells and absent in type 1 diabetes, a condition frequently associated with osteopenia. AMY binds to calcitonin receptors, lowers plasma calcium concentration, inhibits osteoclast activity, and stimulates osteoblasts. In the present study, we examined the effects of AMY replacement on bone loss in a streptozotocin (STZ)-induced rodent model type 1 diabetes. Of 50 male Wistar rats studied, 40 were made diabetic with intraperitoneal STZ (50 mg/kg; plasma glucose concentrations > 11 mM within 5 days). Ten nondiabetic control (CONT) rats received citrate buffer without STZ. Diabetic rats were divided into four groups (n = 10/group) and injected subcutaneously with rat AMY (45 mg/kg), INS (12 U/kg), both (same doses), or saline (STZ; diabetic controls) once per day. After 40 days of treatment and five 24-h periods of urine collection for deoxypyridinoline (DPD), the animals were killed, blood was sampled, and femurs were removed. The left femur was tested for mechanical resistance (three-point bending). The right femur was tested for total, diaphyseal (cortical bone), and metaphyseal (trabecular bone) bone densities using dual-energy X-ray absorptiometry (DXA). Bone was ashed to determine total bone mineral (calcium) content. None of the treatments had any significant effect on femoral length and diameter. Untreated diabetic rats (STZ; 145+/-7N) had lower bone strength than did nondiabetic CONT (164+/-38; p < 0.05). Total bone mineral density (BMD; g/cm2) was significantly lower in STZ (0. 2523+/-0.0076) than in CONT (0.2826+/-0.0055), as were metaphyseal and diaphyseal densities. Diabetic rats treated with AMY, INS, or both had bone strengths and bone densities that were indistinguishable from those in nondiabetic CONT. Changes in bone mineral content paralleled those for total BMD (T-BMD). Plasma osteocalcin (OC) concentration, a marker for osteoblastic activity, was markedly lower in untreated diabetic rats (7. 6+/-0.9 ng/ml); p < 0.05) than in nondiabetic CONT (29.8+/-1.7; p < 0.05) or than in AMY (20.1+/-0.7; p < 0.05). Urinary DPD excretion, a marker for bone resorption, was similar in untreated and AMY-treated diabetic rats (35.0+/-3.1 vs. 35.1+/-4.4 nmol/mmol creatinine), intermediate in rats treated with INS (49.9+/-2.7), and normalized in diabetic rats treated with both agents (58.8+/-8.9 vs. 63.2+/-4.5 in CONT). Thus, in our STZ rat model of diabetic osteopenia, addition of AMY improved bone indices apparently by both inhibiting resorption and stimulating bone formation.

Abstract
High-precision 1H(e,e'p)pi(0) measurements at Q2 = 0.126 (GeV/c)2 are reported, which allow the determination of quadrupole amplitudes in the gamma*N-->Delta transition; they simultaneously test the reliability of electroproduction models. The derived quadrupole-to-dipole ( I = 3/2) amplitude ratios, R(SM) = (-6.5+/-0.2(stat+sys)+/-2.5(mod))% and R(EM) = (-2.1+/-0.2(stat+sys)+/-2.0(mod))%, are dominated by model error. Previous R(SM) and R(EM) results should be reconsidered after the model uncertainties associated with the method of their extraction are taken into account.

Abstract
This study examined differences in the ability to perceive others' emotions in anxious and learning disabled children, as these differences may contribute to these children's unique socio-emotional difficulties and therapeutic needs. Forty-six children ages 8 to 12 with either anxiety disorders (ANX), language-based learning disabilities (LD), both conditions, or neither condition (clinical controls) were compared on the DANVA, a standardized measure of auditory and visual perception of emotion. Group results were then compared to normative data. Using multivariate analyses, significant group differences were found on the auditory portion of the DANVA but not on the visual portion. LD and comorbid children scored lower on several auditory stimuli, especially when presented at low emotional intensity, while ANX and comorbid children showed high accuracy for auditory sadness. Comorbid children also had lower auditory DANVA scores than the normative sample. No interactive effects between ANX and LD were found. ANX and LD each appear to have distinct effects on the auditory perception of others' emotions. Children with both conditions show both effects and differ from normal children in this domain. Replication using larger samples is required.

Abstract
We compared the duration of action of the short-acting alpha(2)-adrenoceptor agonist salbutamol and the long-acting alpha(2)-adrenoceptor agonists salmeterol and formoterol when administered iv or by inhalation in a histamine-induced bronchoconstriction model in the guinea-pig. Following aerosol dosing, maximal bronchoprotector effects were seen for salbutamol, salmeterol and formoterol at concentrations of 1 mg/ml, 100 microg/ml and 30 microg/ml respectively, giving a potency order of formoterol > salmeterol > salbutamol. All displayed similar maximum effects in this system. A maximal concentration of salbutamol showed bronchoprotection at 1 h but not at 3 h post-dosing whereas maximal concentrations of formoterol and salmeterol showed protection up to 5 h post-aqueous-aerosol dosing, giving a duration order of salmeterol > formoterol > salbutamol. All three alpha(2)-adrenoceptor agonists showed dose-dependent bronchoprotection and duration of action following intravenous administration; salbutamol and salmeterol were equipotent and both were less potent than formoterol. Bronchoprotection obtained with sub-maximal concentrations of all three alpha(2)-adrenoceptor agonists faded within 30 min following iv administration, but this could be extended by increasing the doses. These results demonstrate that the route of administration is important in determining the duration of action of alpha(2)-adrenoceptor agonists in the lung. Furthermore, such findings lend support to the suggestion that the physico-chemical characteristics of salmeterol govern its duration of action rather than sustained binding of this agonist to a alpha(2)-adrenoceptor exo-site.

Abstract
OBJECTIVE To determine the expression and localization of cell adhesion molecules intercellular adhesion molecule-1 (ICAM-1), E-selectin, platelet-endothelial cell adhesion molecule (PECAM), and vascular cell adhesion molecule (VCAM) in the cervix and myometrium during pregnancy and labor. METHODS Biopsies of myometrium and cervix were obtained from non-pregnant women and from pregnant women before and after onset of spontaneous labor at term. Cell adhesion molecule mRNA expression was quantified using Northern blotting and cell adhesion molecule protein was localized using immunohistochemistry. RESULTS ICAM-1 mRNA was upregulated in the cervix (10-fold increase, P <.01) and myometrium (10.5-fold increase, P <.01) during labor. ICAM-1 was localized in the vascular endothelium and in leukocytes in the cervix and myometrium from all three groups of women. VCAM mRNA was upregulated in the cervix (2.5-fold increase, P <.01) during pregnancy and there was no further change during labor. VCAM localized weakly to the vascular endothelium in cervical and myometrial biopsies from pregnant and non-pregnant women. PECAM mRNA was significantly upregulated in myometrium during pregnancy (ninefold increase, P <.01) and did not change with the onset of labor. PECAM localized to the vascular endothelium in all cervical and myometrial biopsies and was identified on leukocytes. There were no significant changes in E-selectin mRNA expression in either tissue with pregnancy or parturition. CONCLUSION Cell adhesion molecule expression changes in human cervix and myometrium during pregnancy and parturition. At least part of these changes are attributable to expression by leukocytes infiltrating these tissues.

Abstract
Proper feeding during a baby's first year of life is crucial for a sound nutritional foundation. Because of this, there are several issues that must be addressed to ensure the child is fed properly. First, bottle-feeding moms should not be made to feel guilty about their feeding decision. It is also important to review feeding practices to avoid overfeeding and encourage positive nurturing techniques. Mothers should learn the key signals to watch for from their baby, such as sleep patterns and bowel movements. Also, it is crucial to teach parents the essential issues related to preparing bottles, such as cleaning the bottles and nipples and properly mixing the formula.

Abstract
Cultural teachings and practices greatly influence a mother's feeding decisions. It is important for all health care professionals to understand the cultures within their community and how various beliefs impact infant nutrition. For example, studies have shown the African American and Hispanic mothers are more likely to gain feeding information from family members. There are significant misconceptions being passed down through the generations which can lead to serious nutritional problems, such as overfeeding and the early introduction of cow's milk and food.

Abstract
Special consideration should be given when counseling at-risk mothers. Although local health departments and offices for the Women, Infants, and Children Program (WIC) are teaching mothers about proper feeding practices, there is a large section of the population that does not qualify for government programs and does not have the financial resources to properly feed their children. Considering this group of parents, and the shrinking number of clinics, it is essential that health care professionals educate mothers in at-risk environments to watch for cues from the infant while determining feeding practices.

Abstract
OBJECTIVE To examine the association between early childhood speech and language disorders and young adult psychiatric disorders. METHOD In a longitudinal community study conducted in the Ottawa-Carleton region of Ontario, Canada, interviewers administered structured psychiatric interviews to age 19 participants who were originally identified as speech-impaired only, language-impaired, or nonimpaired at age 5. The first stage of the study took place in 1982 when participants were 5 years old, and the latest stage of the study took place between 1995 and 1997 when participants had a mean age of 19 years. This report examines the association between early childhood speech/language status and young adult psychiatric outcome. RESULTS Children with early language impairment had significantly higher rates of anxiety disorder in young adulthood compared with nonimpaired children. The majority of participants with anxiety disorders had a diagnosis of social phobia. Trends were found toward associations between language impairment and overall and antisocial personality disorder rates. Males from the language-impaired group had significantly higher rates of antisocial personality disorder compared with males from the control group. Age of onset and comorbidity did not differ by speech/language status. The majority of participants with a disorder had more than one. CONCLUSIONS Results support the association between early childhood speech and language functioning and young adult psychiatric disorder over a 14-year period. This association underscores the importance of effective and early interventions.

Abstract
This article presents a critical review of literature reporting the effects on parents of universal neonatal hearing screening (UNHS). It explores how parents experience the process and outcome of screening and in particular focuses on debates surrounding false positive identification, the evidence base for maternal/parental anxiety, consent, and family cultural/sociodemographic influences on the effective implementation of UNHS programs. These issues are then set within the context of events in the United Kingdom, where the Department of Health has recently initiated a program to pilot the introduction of universal neonatal hearing screening at 20 sites in England.

Abstract
The GREAT-ER (Geo-referenced Regional Exposure Assessment Tool for European Rivers) project team has developed and validated an accurate aquatic chemical exposure prediction tool for use within environmental risk assessment schemes. The software system GREAT-ER 1.0 calculates the distribution of predicted environmental concentrations (PECs) of consumer chemicals in surface waters, for individual river stretches as well as for entire catchments. The system uses an ARC/INFO-ArcView (ESRI) based Geographical Information System (GIS) for data storage and visualization, combined with simple mathematical models for prediction of chemical fate. At present, the system contains information for four catchments in Yorkshire, one catchment in Italy, and two in Germany, while other river basins are being added. Great-ER 1.0 has been validated by comparing simulations with the results of an extensive monitoring campaign for two 'down-the-drain' chemicals, i.e. the detergent ingredients boron and Linear Alkylbenzene Sulphonate (LAS). GREAT-ER 1.0 is currently being expanded with models for the terrestrial (diffuse input), air and estaurine compartments.

Abstract
PURPOSE:Gastrin-releasing peptide (GRP) is a 27-amino acid neuropeptide that has been identified in the cytoplasm of many neuroendocrine tumors. Gastrin releasing peptide has been labeled as an autocrine growth factor in small cell lung carcinomas. Recent work has also shown this to be true in the growth of neuroblastoma cells in vitro. The purpose of this study was to demonstrate GRP and its receptor (GRP-R) in resected human neuroblastomas and to correlate the presence or absence with other known predictors of poor prognosis.To demonstrate the presence of GRP and GRP-R mRNA, total RNA was extracted from human neuroblastoma cells. A reverse transcription-polymerase chain reaction (RT-PCR) was then performed using specific primers. The products of the RT-PCR were then confirmed to be GRP and GRP-R cDNA by Southern blot analysis. The RT-PCR products were then sequenced, and these sequences were compared with the know sequences of GRP and GRP-R DNA.N = 19. GRP and GRP-R mRNA were present in all neuroblastoma specimens. Although no correlation with other known predictors of poor prognosis existed, transcripts of four different sizes (400, 450, 500, and 950 bp) were seen in the GRP-R transcripts. The sequences of the 950 bp-sized transcript reverse transcription PCR products were identical to the known GRP-R.We conclude that gastrin releasing peptide and gastrin releasing peptide receptor mRNA are present in all human neuroblastomas. Although qualitatively it appears to lack prognostic significance, its ubiquitous nature in the tumor suggests it may be a useful target on which to base future treatment modalities.

Abstract
Much of the published literature on nurse practitioners relates to nurses with backgrounds, training and nursing experience other than health visiting. Health visitors however may be ideally placed to develop their role in the identification and management of acute childhood illness, and such a development may benefit patients, the health service and health visitors themselves. This study examines the current practice and attitudes of heath visitors in identifying and managing acute childhood illness using a postal questionnaire survey in one community National Health Service (NHS) Trust. The majority of responding health visitors reported that they were already identifying and advising on a range of acute childhood illnesses. Their confidence in undertaking these activities varied by condition. They were less confident in identifying and advising on conditions requiring the use of diagnostic equipment, viral illnesses which are becoming increasingly rare, and those with potentially serious outcomes. More knowledge and more training were seen as methods for increasing confidence. Most health visitors could see advantages in taking on this role; almost two thirds felt it would become part of the role of the health visitor in the future and a high level of interest was expressed in developing such a role.
