Abstract
The purpose of this study was to compare the cognitive and psychomotor effects of the calcium antagonist nisoldipine with placebo in healthy volunteers over the three-week period of this randomised, double-blind, parallel group trial. Thirty volunteers received either a twice-daily dose of 10 mg nisoldipine or placebo. Psychometric testing and measurement of blood pressure and heart rate were carried out on days 0, 7, 14 and 21. Psychometric testing included: Critical Flicker Fusion (CFF), Choice Reaction Time (CRT), Digit Span (DS), Digit Symbol Substitution Test (DSST), and Letter Cancellation (LC). No significant treatment effects were found. CFF performance improved for both groups during the first week. In the CRT task, significant improvements were observed on days 14 and 21, relative to baseline, for total and motor reaction time. Similar improvements over time were found on the LC and DSST tasks. There were no significant differences between the active treatment and placebo for heart rate and systolic/diastolic blood pressure and nisoldipine was well tolerated. The results of this study indicate that nisoldipine does not have any cognition enhancing properties but, unlike some calcium antagonists, it does not markedly impair CNS activity.

Abstract
The experience of cancer recurrence is multifaceted and is influenced by social support, family support and medical and nursing intervention. The diagnosis of recurrence is often more traumatic than the initial diagnosis and the future for the patient becomes less certain. A chronic illness model provides a useful framework for understanding the experience of recurrent cancer. People who are diagnosed with recurrent cancer recognize that it is a time of re-evaluation, transformation and redefinition. Relationships take on an important significance and informational and support needs are paramount. Much of the literature suggests that the role transformation, or the adaptation of the individual to their circumstances, is a central theme of the experience of cancer recurrence. The development of a specific model to assess the role transformation that patients appear to experience in the face of the uncertainty of their recurrent disease, would be invaluable when developing a theoretical framework to guide future research and nursing care.

Abstract
The purpose of this study was to evaluate the toxicity and determine the response rate, duration of remission, and survival using gemcitabine plus carboplatin in non-small cell lung cancer (NSCLC). This was a phase II study of gemcitabine and carboplatin in chemotherapy-naive patients with advanced NSCLC and Karnofsky Performance Status of at least 80. Gemcitabine was administered intravenously at 1,000 mg/m2 weekly for 3 weeks followed by 1 week rest. Carboplatin was administered immediately after gemcitabine at an area under the curve (AUC) of 5 given intravenously on day 1 of an every-4-week cycle. Seven patients were entered in the study and five were evaluable for toxicity. The median age of patients was 68 years (range, 52-72). The protocol was prematurely terminated because of severe and unexpected hematologic toxicity. Grade 3-4 thrombocytopenia was observed in four of the first five patients. These toxicities were all observed with the first course of chemotherapy. There were no objective responses seen. Median survival time was 130 days. Carboplatin plus gemcitabine was a logical combination. However, because of the severe thrombocytopenia associated with this regimen, we do not recommend this two-drug combination in the dose and schedule used in this study.

Abstract
The gene expression of a new group of tumour antigens known as cancer/testis (CT) antigens is now well-recognized in some solid tumours. However, their expression in haematological malignancies remained unclear. In this study, we have used reverse transcription polymerase chain reaction and Southern blot analysis to examine the presence of transcripts for the three CT antigens, NY-ESO-1, SSX2 and SCP1 in haematological malignant cells. We found that transcripts for SCP1 could be detected in 10% of myeloma, 5.7% of acute myeloid leukaemia and 23% of chronic myeloid leukaemia. In contrast, NY-ESO-1 and SSX2 were not detected in any of the 107 tumour samples.

Abstract
Nursing interventions were provided to older men following prostate surgery during a controlled clinical trial examining nursing care and its effects on quality of life outcomes. The Nursing Intervention Lexicon and Taxonomy (NILT), consisting of 7 categories of nursing interventions, was used to classify intervention statements extracted from 32 home care records. Two major categories of interventions were patient teaching (45%) and psychologically based interventions (20%). In a comparison of the types of interventions provided upon discharge from the hospital with those provided at the end of 1 month of home care, it appeared that patients had not yet shifted from the crisis to the chronic phase of their illness course based on Rolland's framework.

Abstract
Little to no data exists in the literature for serum estriol values in non-pregnant, premenopausal women. The current medical community opinion holds that estriol has no significant role in non-pregnant women relative to the other estrogens. It is a possibility that estriol's primary function has yet to be discovered. Accordingly, the first step is to understand cycle-dependent serum estriol concentrations. We have made a preliminary investigation for serum estriol concentration of 26 women during the known cycle peaks of estrone and estradiol. Five of the women were also tested for serum estriol on various days throughout the cycle in order to develop a cycle-dependent concentration profile. The result of these experiments show that serum estriol was always significantly higher than the sum of estrone and estradiol and less fluctuating. We conclude that estriol is probably a significant estrogen component.

Abstract
BACKGROUND General practitioners (GPs) do not routinely receive information about the deaths of those patients whose death certificates they have not completed. We developed and evaluated a system for producing death registers for GPs. AIM To evaluate GPs' and practice managers' views on, and uses of, the death register. METHOD General practitioners in Newcastle (n = 161) and Sunderland Family Health Service Authority (n = 144) areas were sent a questionnaire on their sources and use of information about patients' deaths. Death registers were sent to Newcastle practices; Sunderland practices were the control group. A follow-up questionnaire was sent to Newcastle (n = 173) and Sunderland (n = 140) GPs after two years. Newcastle practice managers (n = 45) were interviewed after their practice had received death registers for one year. RESULTS Ninety-two per cent of Newcastle responders had seen the death register. Seventy-three per cent saw it regularly. Of those who saw it, 92% found it useful for communication within the primary health care team, bereavement follow-up, and administration and medical audit. One fifth of GPs named the death register as their first source of information about their patients' deaths. Newcastle GPs reported greater levels of change in use of patient death information than the control group. Practice managers circulated, used, and recorded information from the death register. CONCLUSION Death registers are valued and have demonstrable benefits with regard to administration, bereavement care, and medical audit.

Abstract
The purposes of this study were to examine the relationship between: (1) nurses' ratings of pain and corresponding administration of pain medication to elderly long-term care residents, and (2) cognitive status of the elderly and pain medication orders/administration. Participants were 83 residents, 60 years of age and older, in two groups: cognitively impaired (n = 64), and cognitively intact (n = 19). For comparison purposes, 19 of the cognitively impaired subjects were matched on age and diagnosis to provide control for potentially painful conditions. A retrospective medication review of the resident's charts was conducted to compare medication orders and administration on analgesics that were scheduled and p.r.n. (given as needed). The pain ratings of 25 RNs using a visual analogue scale were correlated with pain medications given to the resident on the day of the rating. Results indicated that RNs' ratings of resident pain and the administration of pain medications were not significantly correlated. In addition, cognitively impaired residents were prescribed significantly less scheduled medication and received significantly less pain medication (either p.r.n. or scheduled) than the cognitively intact elderly. Implications for practice and research are discussed.

Abstract
Functional magnetic resonance imaging (fMRI) has been performed on a standard 1 T system using a pulse sequence developed to utilize blood oxygen level dependent (BOLD) contrast and an off-line analysis routine using correlation techniques. The sequence and the data analysis routine have been validated by reproducing the conventional hand movement paradigm studies reported by numerous other workers. Our work has then been extended to investigate cerebral foci for a tonic pain stimulus and the cortical representation of oesophageal stimulation. Both these studies relate to paradigms where the expected BOLD signal is significantly less than that encountered for motor or visual cortex paradigms. The results show good agreement with other modalities (positron emission tomography, magnetoencephalography and cortical evoked potentials). Performing fMRI at 1 T is slightly controversial. However, our successful study of demanding paradigms, using a standard clinical 1 T imaging system, has important implications for many other users operating at this field strength.

Abstract
Residential fires result in loss of life, property, and displacement from one's neighborhood. It would be expected that grief experienced in the aftermath of residential fires has a significant impact on survivor's recovery and reintegration into the community. Although there is some research on psychological responses to community-wide fires and large scale disasters, little is known about such responses among survivors of home fires that occur episodically. Appropriate interventions cannot be developed until more is learned about variables influencing survivors' psychological response to a residential fire. A theoretical model of survivors' psychological response post-fire is proposed.

Abstract
BACKGROUND Although some studies have examined the effects of terminal illness care models such as hospice care on survivor outcomes, no studies could be found that examined whether nursing care affected such outcomes. OBJECTIVE To determine whether specialized oncology home care services provided to terminally ill patients with lung cancer positively influenced bereavement psychological distress among survivors, compared with other models of care. METHODS A secondary analysis was performed to test the effects of home nursing care for terminally ill patients on spousal psychological distress during bereavement. Forty-six patient-spousal dyads were randomly assigned to either an oncology home care group (OHC), a standard home care group, or an office care control group. Patient-spousal dyads were entered into the study 2 months after the patient's diagnosis of lung cancer and received follow-up until the patient died. Bereaved spouses continued to receive follow-up for 25 months after the patient's death. RESULTS Psychological distress was significantly lower initially among spouses of patients that received the OHC intervention compared with the other two groups. Significant mean group differences were found on the subscales of depression and paranoid ideation; marginal group differences were found on the subscales of hostility and psychoticism. There were no significant differences among the groups at 25 months. CONCLUSIONS These results suggest that the bereaved's psychological distress can be positively influenced depending on how their loved one is cared for during the terminal phase of illness.

Abstract
STUDY DESIGN This report examines a technique for measurement of axial vertebral rotation using magnetic resonance imaging. OBJECTIVES To assess the reproducibility of three-dimensional magnetic resonance imaging in the measurement of vertebral rotation at individual endplates in patients with adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA Deformity in the sagittal and coronal planes in patients with adolescent idiopathic scoliosis can be readily assessed from plain radiographs, but the degree of deformity in the axial plane is more difficult to determine. Plain film techniques have inherent inaccuracies because of loss of definition of anatomic landmarks, and the use of computed tomography is limited by the high radiation dose associated. Magnetic resonance imaging provides a means of imaging scoliotic deformity that allows multiplanar reconstruction and that involves no use of ionizing radiation. METHODS Ten patients with adolescent idiopathic scoliosis were imaged in a Siemens 1-Tesla impact scanner. Three-dimensional volume images of the apical five vertebrae were obtained in the axial plane and were postprocessed through multiplanar reconstruction. Sections through the superior and inferior endplates of each vertebra were selected in the sagittal and coronal planes, allowing axial reconstructions to be obtained in the plane of each endplate. Vertebral rotation was measured by identifying datum points on the inner surfaces and at the junction of the laminas and comparing the angle subtended by these points with a vertical drawn by the computer. Measurements were obtained from the single scanning sequence on two occasions by one observer and on one occasion by a second observer. Interobserver and intraobserver error was evaluated and correlation with readings obtained from plain films using Perdriolle's torsiometer method assessed. RESULTS The interobserver variation had a mean of 3.02 degrees (range, 0-10 degrees) and a 95% confidence interval of [2.51 degrees, 3.53 degrees]. The intraobserver variation had a mean of 2.56 degrees (range, 0-7 degrees) and a 95% confidence interval of [1.83 degrees, 3.29 degrees]. The mean difference between measurements obtained from magnetic resonance imaging and plain film was 3.29 degrees (range, 0-12 degrees) with a 95% confidence interval of [1.43 degrees, 5.15 degrees]. CONCLUSIONS The degree of vertebral rotation can be accurately and reproducibly assessed by three-dimensional magnetic resonance imaging. Measurements can be made through individual endplates that allow assessment of the relative amount of intervertebral and intravertebral deformity.

Abstract
The Corbin and Strauss Trajectory Model proposed that nursing care should differ along a trajectory of eight phases to meet patients' and families' needs. Seventy-nine patients with breast, prostate, or gastrointestinal cancer were determined to be in either the stable or the unstable phase of their illness. Contrary to expectations, documented nursing interventions did not significantly differ between stable and unstable trajectory phases, although significant differences were found when comparisons were made across cancer sites. These findings suggest that the trajectory framework may require modification for use with oncology patients.

Abstract
Completion of genetic and physical maps requires markers from the ends (telomeres) of every human chromosome. We have searched for short tandem repeats (microsatellites) in cosmid and P1 clones and generated 661 sequence-tagged sites (STS) from the terminal 300 kb of 31 human chromosome ends. PCR assays were successfully designed for 58 microsatellites and mapped both genetically and on radiation hybrids (RHs) to confirm their telomeric location. Sequence analysis revealed marked variation in sequence composition, consistent with the hypothesis that even very highly GC-rich chromosome bands (the T bands) are not homogenous. The STSs that we have generated will be a necessary resource for the construction of physical maps of these complex regions of the genome.

Abstract
Cuba's accomplishments in primary care, while controversial, include several developments pertinent to family medicine. These accomplishments involve low-technology and organizational innovations such as neighborhood-based family medicine as the focus of primary care; regionalized systems of hospital services and professional training; innovative public health initiatives and epidemiologic surveillance; universal access to services without substantial barriers related to race, social class, gender, and age; and active programs in treatments such as "green medicine" and "thermalism." High-technology achievements include innovations in pharmacology and biotechnology, surgical procedures, and care of patients infected by the human immunodeficiency virus (HIV). Limited access to Cuban publications, impediments to presentations by Cuban health care professionals at professional meetings, and the prohibition on importing products of Cuban biotechnology to the United States inhibit a detached, scientific appraisal of Cuba's accomplishments. Cuba's isolation from the US clinical and research communities has prevented interchanges that would improve primary care services in both countries.
