Incomplete holism in pre-registration nurse education: the position of the biological sciences

There is an ongoing debate in nurse education concerning the role and delivery of the biological sciences in the nursing curriculum. One of the fundamental questions raised by this debate asks how best can teachers impart biological knowledge in a manner that can be readily applied by students and qualified nurses to inform their clinical practice. This paper will include a discussion of some of the features of pre-registration education that may have influenced the manner in which biological sciences are perceived, taught and used by nurses. It will be argued that nursing may have developed a form of incomplete holism and that this may be in part responsible for the challenges that remain to be met within this area of the nursing curriculum. As a response to incomplete holism an innovative approach within pre-registration education will be introduced. This development involves the use of linked teaching sessions which aim to develop the analytical skills necessary to apply physiological knowledge to nursing practice.     

Project 2000: perceptions of the philosophy and practice of nursing: shifting perceptions—a new practitioner?

This is the first of two papers which address aspects of the findings of a large scale study commissioned by the English National Board which set out to examine the impact of Project 2000 on perceptions of the philosophy and practice of nursing. The findings presented here suggest that there have been fundamental shifts in perceptions of the nature and discipline of nursing. Students and diplomates of the course perceive themselves as knowledgeable doers, with their practice well grounded in theory and research. They value the interpersonal skills teaching and place the patient firmly at the centre of care delivery, viewing the patient holistically and being prepared to be fierce patient advocates where necessary. It is difficult to determine the extent to which these shifts can be attributed to the Project 2000 course, although the Project 2000 approach to education appears to be an important factor.     

Antenatal Screening for HPA-la by Flow Cytometry

Summary: regnant women who attended antenatal clinics at King George V Hospital, the Birth Centre or were referred by obstetricians from February to July. 1996 were screened for the platelet antigen HPA-la by flow cytometry. Forty out of 2300 (1.7%) were found to be negative for this antigen . Of the 28 women followed throughout their pregnancy, none developed antibody to HPA-la. Platelet counts performed on samples from 17 babies born to 17 of these mothers were all normal. This study proves the simplicity and rapidity of flow cytometry for platelet antigen screening. The results were comparable with the Solid Phase Red Cell Adherence (SPRCA) method and with PCR. The lack of a plentiful supply of specific antibody and the rarity of fetomaternai alloimmune thrombocytopenia (FMAIT) argue against the introduction of routine screening for maternal HPA-la status at the present time.     

Nephrectomy during operative management of retroperitoneal sarcoma

Background: Complete resection of a retroperitoneal sarcoma often requires removal of adjacent organs. In this study we evaluated the role of nephrectomy during operation for retroperitoneal sarcoma. Methods: Between July 1982 and July 1995, 75 of the 371 (20%) patients who underwent resection of retroperitoneal sarcoma at MSKCC underwent concommitant nephrectomy. Data concerning the reasons for nephrectomy, degree of sarcomatous renal involvement, and survival were retrospectively analyzed. Results: Fifty-four patients (72%) underwent nephrectomy during the initial resection, and 21 (28%) during a resection of a recurrent or persistent tumor. The most common reason for nephrectomy was total encasement by sarcoma (n=40; 53%), followed by dense adherence of the tumor to the kidney (n=21; 28%), and the direct invasion of the kidney by tumor (n=2; 3%). Pathology demonstrated an absence of kidney invasion in the majority of cases (55 of 75; 73%). Renal capsular invasion was present in 11 of 75 (15%), renal parenchymal invasion in 7 of 75 (9%), and renal vein invasion in 2 of 75 (3%) of cases. There were no significant differences in survival based on degree of sarcoma involvement of the kidney, tumor grade, or whether the resection was for primary or recurrent disease. The 53 patients who underwent a complete gross resection of all tumor had a significantly improved long-term survival compared to the 20 patients who did not (50% versus 20% DFS at 5 years, respectively; p<0.001). Conclusions: Decisions for concomitant nephrectomy during resection of retroperitoneal sarcoma should be based on whether this maneuver will provide a complete resection of all gross tumor, in which case the long-term disease-free survival of 50% is comparable to the reported 5-year survival of all patients with retroperitoneal sarcoma who are completely resected.

Increased salt retention and hypertension from non-steroidal agents in the elderly

We studied blood pressure and natriuretic responses to acute salt loading, and the effect of non-steroidal anti-inflammatory agents on these responses, in five healthy normotensive women aged 65 to 71 years. Five women aged 25 to 31 years acted as controls. Intravenous saline loading, with and without prior ingestion of ibuprofen, was 15 ml/kg/h for 3 h. Baseline blood pressures were higher in the elderly. Saline infusion without ibuprofen raised systolic blood pressure (SBP) by about 25 mmHg in the older group only. Ibuprofen increased baseline SBP in the elderly (129 +/- 6 vs. 116 +/- 5 mmHg, p < 0.05). Saline loading after ibuprofen again raised blood pressure by about 25 mmHg in the elderly only. The elderly group showed markedly increased sodium excretion during saline loading, but this was reduced by ibuprofen. Ibuprofen had no effect on SBP or sodium excretion in controls. Ageing appears to increase susceptibility to salt retention and hypertension from non-steroidal anti-inflammatory agents.      

1986 Association of Residents in Radiation Oncology Survey

Two simultaneous surveys were conducted by the Association of Residents in Radiation Oncology (ARRO). A survey of all residents in Radiation Oncology was conducted to obtain information on trends in residency training. A simultaneous survey of Chief Residents was obtained to determine more specific information on current training programs. Over one-half of residents responded. Eighty-eight percent of respondents were graduates of a North American medical school. Most did at least an internship prior to entering Radiation Oncology and 3/4 of those who did not do a separate internship rotated through other areas at a later time to broaden their knowledge. One-half are Board certified or Board eligible in another specialty or hold a Masters or Ph.D. degree. Three-quarters of all residents had authorship of at least one paper during training and one-half were primary authors. Eighty percent felt adequately prepared for practice after residency. One-half plan at least an initial post-residency affiliation with an academic center. Many were concerned that Radiation Oncologists are not afforded respect equivalent to that of other specialties. Ninety-eight percent favored departmental status for Radiation Oncology. Resident recommendations for improving the image of Radiation Oncology are presented.     

Noninvasive Estimation of Blood Alcohol Concentrations: Ethanol Vapor Above the Eye

The present study describes, in animals, a novel approach to the in vivo, noninvasive determination of alcohol in the body. The concentration of ethanol in vapor above the lacrimal fluid in the eye was analyzed in situ by the use of a fast (1-min) gas sensor method developed previously for biological liquids. After an oral dose of 1 g/kg to 11 animals, eye vapor measurements and blood samples were obtained over 4 hr. The correlation of 61 blood ethanol concentrations obtained by the two methods yielded a correlation coefficient of 0.92 and a slope of 0.99. The metabolic rates of ethanol determined by gas chromatographic analysis of blood and by ethanol eye vapor analysis are virtually identical. The data suggest that ethanol eye vapor analysis may be an attractive, noninvasive method for the determination of ethanol in animals. The method is not subject to false high readings due to alcohol in the buccal cavity and thus might constitute an alternative to breath analysis in the human. In a separate series, ethanol was determined by head space gas chromatography in samples of blood and lacrimal fluid while the animals were under ketamine anesthesia. The correlation of ethanol concentrations in blood and lacrimal fluid (r = 0.99) shows that ethanol is distributed in lacrimal fluid which comprises part of total body water.     

Event-related Potentials as Markers for Alcoholism Risk in High Density Families

One hundred sixty-eight adult siblings and parents from affected and control families were tested for ERP characteristics using two tasks involving an auditory oddball paradigm. Significant within family differences among affected families suggest that risk for developing alcoholism may be seen even in adult subjects who have had experience consuming alcohol. Further, analysis of quantity and recency of drinking in the past seven days were not correlated with either amplitude or latency of P300, suggesting that the within-family differences observed reflect relative risk for developing alcoholism rather than experience with alcohol.
