Undergraduate nursing students' responses to an end-of-life educational session

End-of-life care is an important component of healthcare students' education. The purpose of this study was to explore nursing students' perspectives of end-of-life decision-making and end-of-life care following an ethics session during the 2020-2021 academic year. A qualitative study was performed. Thirty-six undergraduate nursing students in their junior year at a private, Catholic university located in the northeast United States participated. Two nursing faculty and one bioethicist conducted an educational session on end-of-life care developed with a focus on decision-making, autonomy and dignity while employing debate pedagogy as a teaching modality. Following the session, the students were given a letter of solicitation with a link to a Qualtrics survey with four open ended questions related to end-of-life care. Four main themes, as being perceived by students, were discovered: decision-making, autonomy, the nurses' role, and the interprofessional team as important components of end-of-life care. Implications for future research include debate pedagogy as a method to teach end-of-life care and ethical decision-making as well as quantitative research or mixed methods with larger sample sizes and across health professions.

A quality improvement approach to develop an educational initiative for an age-friendly health system

Authors describe a quality improvement approach to develop and pilot test educational materials with an aim to educate MinuteClinic providers in the provision of age-friendly care using the 4Ms Framework: What Matters, Medication, Mentation, Mobility. The team used surveys, focus groups and site visits to develop educational prototypes with Plan-Do-Study-Act iterative cycles to improve the education. Educational materials introduced providers to 4Ms assessment and evidence-based act on strategies for older adults in the convenient care setting. The education activities included an interactive orientation module comparing standard care to 4Ms care, 10 video vignettes with experts addressing gerontological topics, and 12 grand rounds presented monthly on topics applying the 4Ms with older adults. The information gained from the staff aided in the development and the iterative improvement of the materials. This article highlights the benefits of using a quality improvement approach in development of clinician education in provision of age-friendly care.

Pragmatic Trials in Long-Term Care: Implementation and Dissemination Challenges and Opportunities

Randomized controlled trials are considered the most rigorous research design in efficacy and effectiveness research; however, such trials present numerous challenges that limit their applicability in real-world settings. As a consequence, pragmatic trials are increasingly viewed as a research design that overcomes some of these barriers with the potential to produce findings that are more reproducible. Although pragmatic methodology in long-term care is receiving increasing attention as an approach to improve successful dissemination and implementation, pragmatic trials present complexities of their own. To address these complexities and related issues, experts with experience conducting pragmatic trials, developing nursing home policy, participating in advocacy efforts, and providing clinical care in long-term care settings participated in a virtual consensus conference funded by the National Institute on Aging in Spring 2021. Participants identified 4 cross-cutting principles key to dissemination and implementation of pragmatic trial interventions: (1) stakeholder engagement, (2) diversity and inclusion, (3) organizational strain and readiness, and (4) learn from adaptations. Participants emphasized that implementation processes must be grounded in the perspectives of the people who will ultimately be responsible for implementing the intervention once it is proven to be effective. In addition, messaging must speak to long-term care staff and all others who have a stake in its outcomes. Although our understanding of dissemination and implementation strategies remains underdeveloped, this article is designed to guide long-term care researchers and community providers who are increasingly aware of the need for pragmatism in disseminating and implementing evidence-based care interventions.

El papel de la evaluación en la enfermería de práctica avanzada gerontológica basada en competencias

RESUMEN El envejecimiento de la población es un desafío a los sistemas de salud y requiere que los profesionales de enfermería en gerontología de práctica avanzada (EGPA) aborden los requisitos específicos y complejos del cuidado de los adultos mayores. La EGPA pone en ejecución prácticas basadas en evidencia dirigidas a pacientes y familiares para la promoción y protección de la salud, prevención de enfermedades, así como su recuperación y rehabilitación. En la gerontología de práctica avanzada basada en competencias, la evaluación integral es esencial para la puesta en práctica de un plan de cuidados. En este ensayo teórico reflexionamos sobre el papel de la evaluación en la enfermería en gerontología de práctica avanzada basada en competencias. Desde nuestro punto de vista, la valoración gerontológica hacia una práctica excelente debe ser integral, multidimensional, interdisciplinar y planificada. La EGPA debe abarcar competencias efectivas en habilidades clínicas y prácticas del cuidado; alfabetización en salud; cuidado colaborativo; gestión de sistemas para la continuidad del cuidado; ética, defensa y agencia moral; y la práctica a través de la investigación basada en la evidencia. Los modelos gerontológicos de cuidado y las competencias de la EGPA sirven como marco de su práctica, mientras que la evaluación es fundamental para un cuidado accesible a los adultos mayores.

The role of assessment in competence-based gerontological advanced practice nursing

ABSTRACT Population aging challenges healthcare systems, requiring gerontological advanced practice nurses (GAPN) to address specific and complex care requirements of older adults. GAPN implement evidence-based practices directed to patients and families, focusing on health promotion and protection, disease prevention, recovery, and rehabilitation. In competence-based gerontological advanced practice, comprehensive geriatric assessment is essential for implementing the care plan. In this theoretical essay we reflect about the role of assessment in competence-based advanced nursing practice directed to the care of older adults. From our perspective, geriatric assessment for a high-quality practice must be comprehensive, multidimensional, interdisciplinary, and planned. GAPN must have solid competencies for clinical skills and caring practices; education for health literacy; collaborative care; system management for continuity of care; ethics, advocacy, and moral agency; and evidenced-based practice inquiry. Gerontological models of care and GAPN competencies serve as frameworks to guide practice while assessment is fundamental for providing age-friendly care to older adults.

A Scoping Review of the Evidence About the Nurses Improving Care for Healthsystem Elders (NICHE) Program

BACKGROUND AND OBJECTIVES

The Nurses Improving Care for Healthsystem Elders (NICHE) is a nurse-led education and consultation program designed to help health care organizations improve the quality of care for older adults. To conduct a scoping review of the evidence associated with the NICHE program to (a) understand how it influences patient outcomes through specialized care of the older adult and (b) provide an overview of implementation of the NICHE program across organizations as well as its impact on nursing professionals and the work environment.

RESEARCH DESIGN AND METHODS

Six databases were searched to identify NICHE-related articles between January 1992 and April 2019. After critical appraisal, 43 articles were included.

RESULTS

Four thematic categories were identified including specialized older adult care, geriatric resource nurse (GRN) model, work environment, and NICHE program adoption and refinement. Specialized older adult care, a key feature of NICHE programs, resulted in improved quality of care, patient safety, lower complications, and decreased length of stay. The GRN model emphasizes specialized geriatric care education and consultation. Improvements in the geriatric nurse work environment as measured by perceptions of the practice environment, quality of care, and aging-sensitive care delivery have been reported. NICHE program adoption and refinement focuses on the methods used to improve care, implementation and adoption of the NICHE program, and measuring its impact.

DISCUSSION AND IMPLICATIONS

The evidence about the NICHE program in caring for older adults is promising but more studies examining patient outcomes and the impact on health care professionals are needed.

Graduate level health professions education: how do previous work experiences influence perspectives about interprofessional collaboration?

Understanding how previous experiences with interprofessional education and collaboration inform health care provider perspectives is important for developing interprofessional interventions at the graduate level. The purpose of this study was to examine how previous work experiences of graduate level health professions students inform perspectives about interprofessional education and collaboration. Drawing from program evaluation data of two separate graduate level interprofessional education interventions based in primary care and home health care, we conducted a qualitative secondary data analysis of 75 interviews generated by focus groups and individual interviews with graduate students from 4 health professions cadres. Using directed content analysis, the team coded to capture descriptions of interprofessional education or collaboration generated from participants' previous work experiences. Coding revealed 173 discrete descriptions related to previous experiences of interprofessional education or collaboration. Three themes were identified from the analysis that informed participant perspectives: Previous educational experiences (including work-based training); previous work experiences; and organizational factors and interprofessional collaboration. Experiences varied little between professions except when aspects of professional training created unique circumstances. The study reveals important differences between graduate and undergraduate learners in health professions programs that can inform interprofessional education and collaboration intervention design.

Senior Oral Health: A Community-Based, Interprofessional Educational Experience for Nursing and Dental Students

The current article highlights an interprofessional, older adult oral health community program, created through an Accelerating Interprofessional Community-Based Education and Practice grant from the National Center for Interprofessional Practice and Education, designed to address the gap between older adult health education and care delivery. This project developed an advanced practice, nurse-led partnership among The Hartford Institute for Geriatric Nursing and the Oral Health Nursing Education and Practice Program (both located at New York University Rory Meyers College of Nursing), New York University College of Dentistry, and Regional Aid for Interim Needs (RAIN), a community service organization for older adults in the Bronx. Teams of nursing (n = 26), nurse practitioner (n = 16), and dental (n = 64) students provided oral health education and oral hygiene instruction using Tooth Wisdom^® educational materials to older adults, home health aides (HHAs), and volunteers in nine RAIN senior centers. Students demonstrated increases in their self-reported interprofessional competencies based on the Interprofessional Collaborative Competency Attainment Survey. Results also revealed that older adults (n = 500), HHAs (n = 142), and volunteers (n = 21) at the RAIN senior centers who attended the Tooth Wisdom presentation demonstrated an increase in oral health knowledge.

Provider Perspectives of Medication Complexity in Home Health Care: A Qualitative Secondary Data Analysis

A primary service provided by home care is medication management. Issues with medication management at home place older adults at high risk for hospital admission, readmission, and adverse events. This study sought to understand medication management challenges from the home care provider perspective. A qualitative secondary data analysis approach was used to analyze program evaluation interview data from an interprofessional educational intervention study designed to decrease medication complexity in older urban adults receiving home care. Directed and summative content analysis approaches were used to analyze data from 90 clinician and student participants. Medication safety issues along with provider–provider communication problems were central themes with medication complexity. Fragmented care coordination contributed to medication management complexity. Patient-, provider-, and system-level factors influencing medication complexity and management were identified as contributing to both communication and coordination challenges.

Geriatric Interdisciplinary Team Training 2.0: A collaborative team-based approach to delivering care

Interprofessional collaborative education and practice has become a cornerstone of optimal person-centered management in the current complex health care climate. This is especially important when working with older adults, many with multiple chronic conditions and challenging health care needs. This paper describes a feasibility study of the Geriatric Interdisciplinary Team Training 2.0 (GITT 2.0) program focused on providing interprofessional care to complex and frail older adults with multiple chronic conditions. A concurrent triangulation mixed-methods design facilitated program implementation and evaluation. Over three years (2013-2016), 65 graduate students from nursing, midwifery, social work, and pharmacy participated along with 25 preceptors. Participants were surveyed on their attitudes toward interprofessional collaboration pre and post-intervention and participated in focus groups. While attitudes toward interprofessional collaboration did not change quantitatively, focus groups revealed changes in language and enhanced perspectives of participants. Based on the evaluation data, the GITT 2.0 Toolkit was refined for use in interprofessional education and practice activities related to quality initiatives.

Validating the Health Literacy Promotion Practices Assessment Instrument

Background:

How health care professionals address health literacy as part of the provider-client relationship is important for prevention and promoting self-management and symptom management. Research usually focuses on patients' health literacy and fails to examine provider practices, thus leaving a gap in the literature and patient outcomes analyses.

Objective:

The study tested the reliability and validity of a series of questions developed to evaluate health care provider health literacy promotion practices on an interprofessional sample.

Methods:

This exploratory cross-sectional study took place between 2013 and 2015. Participants included graduate level health professions students from nursing, midwifery, medicine, pharmacy, and social work. Exploratory factor analyses with varimax rotation examined the reliability and validity of the instrument as a measure of health literacy promotion practices.

Key Results:

Of the participants in the programs, 198 completed the health literacy questions in the online survey. Exploratory factor analysis showed that questions loaded on two factors connected with either individual or organizational characteristics that facilitated health literacy promotion practices. The Cronbach's alpha for the instrument was 0.95.

Conclusions:

This study helped determine the reliability and validity of the items as measures of providers' health literacy practices. Future research will help to further establish the stability of the instrument as a measure and increase its potential reliability when linking provider practices to health literacy sensitive client outcomes. Testing the instrument separately and concurrently with each health profession is recommended until instrument stability across professional roles has been established. [Health Literacy Research and Practice. 2017;1(4):e239–e246.]

Plain Language Summary:

We sought to develop a survey instrument people could use to assess how health care providers help patients understand their health better. After getting responses from 198 health care providers, we ran statistical tests to check the quality of the questions for measuring provider practices. We found the questions were good at evaluating provider practices around promoting patient understanding of health issues.

Identifying distinct risk profiles to predict adverse events among community-dwelling older adults

Preventing adverse events among chronically ill older adults living in the community is a national health priority. The purpose of this study was to generate distinct risk profiles and compare these profiles in time to: hospitalization, emergency department (ED) visit or death in 371 community-dwelling older adults enrolled in a Medicare demonstration project. Guided by the Behavioral Model of Health Service Use, a secondary analysis was conducted using Latent Class Analysis to generate the risk profiles with Kaplan Meier methodology and log rank statistics to compare risk profiles. The Vuong-Lo-Mendell-Rubin Likelihood Ratio Test demonstrated optimal fit for three risk profiles (High, Medium, and Low Risk). The High Risk profile had significantly shorter time to hospitalization, ED visit, and death (p < 0.001 for each). These findings provide a road map for generating risk profiles that could enable more effective targeting of interventions and be instrumental in reducing health care costs for subgroups of chronically ill community-dwelling older adults.

A post-master's advanced certificate in gerontology for NPs

This article describes an innovative post-master's advanced certificate in gerontology program developed by the Hartford Institute for Geriatric Nursing at the New York University Rory Meyers College of Nursing. The program provides advanced practice registered nurses geriatric content to meet eligibility criteria for the Adult-Gerontology Primary Care NP certification exam and develops interprofessional care providers to care for complex older adults.

Analysis of measurement tools of fear of falling for high-risk, community-dwelling older adults

Fear of falling has many health consequences among older adults and may lead to curtailment of activities, immobility, functional dependence, falls, and serious injury. The lack of clarity as to how to best measure fear of falling among high-risk, community-dwelling older adults defined as those who are nursing home eligible, functionally dependent, and vulnerable is further complicated by the multiple definitions used throughout the science. Fear of falling is important to measure effectively if we are to develop and test interventions to promote safe aging in place and prevent injury and institutionalization. This integrative review, 1982 to the present, leads to the conclusion that the Falls Efficacy Scale-International (FES-I) long form stands out as the most appropriate measurement tool to best assess fear of falling in this unique, understudied, and underserved population.

How to try this: the Geriatric Depression Scale: Short Form

Depression is underrecognized in older adults, especially those with chronic conditions such as heart disease and arthritis. Left untreated, depression may progress and have dramatic effects on overall health. The Geriatric Depression Scale: Short Form is a 15-question screening tool for depression in older adults that takes five to seven minutes to complete and can be filled out by the patient or administered by a provider with minimal training in its use. The questions focus on mood; the score can help clinicians decide whether further assessment is needed. (This screening tool is included in a series, Try This: Best Practices in Nursing Care to Older Adults, from the Hartford Institute for Geriatric Nursing at New York University's College of Nursing.)

Plasma cells in muscle in inclusion body myositis and polymyositis

BACKGROUND

Previous immunohistochemical studies of muscle from patients with inclusion body myositis and polymyositis found many more T cells than B cells, suggesting a role for intramuscular cell-mediated immune mechanisms rather than humoral mechanisms.

METHODS

Microarray studies were performed on muscle biopsy specimens from 40 patients with inclusion body myositis (IBM; n = 23), polymyositis (PM; n = 6), and without neuromuscular disease (n = 11). Reverse transcription PCR of selected immunoglobulin gene transcripts was performed on two patient samples. Qualitative immunohistochemical studies for B-cell lineage cell surface markers were performed on 28 muscle specimens and quantitative studies performed on a subset of 19 untreated patients with IBM or PM. CD138+ cells were isolated from muscle using laser capture microdissection, and immunoglobulin transcripts were PCR amplified to determine the presence or absence of immunoglobulin gene rearrangements unique to the B-cell lineage.

RESULTS

Immunoglobulin gene transcripts accounted for 59% in IBM and 33% in PM of the most stringently defined highest differentially expressed muscle transcripts compared with normal. Plasma cells, terminally differentiated B cells expressing CD138 but not CD19 or CD20, are present in IBM and PM muscle in numbers several times higher than B cells.

CONCLUSIONS

There are differentiated B cells in the form of CD138+ plasma cells within the muscle of patients with inclusion body myositis and polymyositis. The principle of linked recognition of B-cell activation predicts several strategies for autoantigen discovery that could not otherwise be pursued through the study of the infiltrating T-cell population alone.

Molecular profiles of inflammatory myopathies

OBJECTIVE

To describe the use of large-scale gene expression profiles to distinguish broad categories of myopathy and subtypes of inflammatory myopathies (IM) and to provide insight into the pathogenesis of inclusion body myositis (IBM), polymyositis, and dermatomyositis.

METHODS

Using Affymetrix GeneChip microarrays, the authors measured the simultaneous expression of approximately 10,000 genes in muscle specimens from 45 patients in four major disease categories (dystrophy, congenital myopathy, inflammatory myopathy, and normal). The authors separately analyzed gene expression in 14 patients limited to the three major subtypes of IM. Bioinformatics techniques were used to classify specimens with similar expression profiles based on global patterns of gene expression and to identify genes with significant differential gene expression compared with normal.

RESULTS

Ten of 11 patients with IM, all normals and nemaline myopathies, and 10 of 12 patients with Duchenne muscular dystrophy were correctly classified by this approach. The various subtypes of inflammatory myopathies have distinct gene expression signatures. Specific sets of immune-related genes allow for molecular classification of patients with IBM, polymyositis, and dermatomyositis. Analysis of differential gene expression identifies as relevant to disease pathogenesis previously reported cytokines, major histocompatibility complex class I and II molecules, granzymes, and adhesion molecules, as well as newly identified members of these categories. Increased expression of actin cytoskeleton genes is also identified.

CONCLUSIONS

The molecular profiles of muscle tissue in patients with inflammatory myopathies are distinct and represent molecular signatures from which diagnostic insight may follow. Large numbers of differentially expressed genes are rapidly identified.

Gerontologic nurse practitioner preceptor guide

Geriatric nurse practitioners (GNPs) often serve as clinical preceptors for nurse practitioner students. The Nursing Interest Group of the John A. Hartford Foundation's Geriatric Interdisciplinary Team Training Program recognized a need for a condensed guide that clarifies the role of a GNP preceptor. This guide uses information from the literature to clarify the role of the preceptor, offer suggestions for clinical teaching, provide guidance to determine expectations for student performance, and delineate the progression of a nurse practitioner student. This article reviews the contents of the guide and offers suggestions for its use in clinical practice.

Inflammatory myopathy associated with mixed connective tissue disease and scleroderma renal crisis

Mixed connective tissue disease is a rheumatological syndrome with neuromuscular manifestations that may include inflammatory myopathy and carpal tunnel syndrome. We report a patient who presented with an inflammatory myopathy and bilateral carpal tunnel syndrome prior to the diagnosis of a connective tissue disorder. Early in the course of treatment, a syndrome of acute renal failure developed. Knowledge of this syndrome, scleroderma renal crisis, and its possible relation to corticosteroid treatment is important to clinicians involved in the management of patients with inflammatory myopathies.

DNA microarray gene expression analysis technology and its application to neurological disorders

DNA microarray technology is currently an area of great interest. Also called "genechip" technology, it incorporates molecular genetics and computer science on a massive scale. This technology can rapidly provide a detailed view of the simultaneous expression of entire genomes and provide new insights into gene function, disease pathophysiology, disease classification, and drug development. In this review, the author discusses the basic theory behind genechip and the other biologic chip technologies, their limitations given the current state of biologic knowledge and computational abilities, and their potential applications to the understanding of neurologic disorders.

Methodologic issues in conducting research on hospitalized older people

OBJECTIVE

To describe challenges in conducting research with hospitalized geriatric patients.

DESIGN

Quasi-experimental longitudinal study with inperson interviews at baseline and discharge and a three-month postdischarge telephone interview. Study protocol required baseline interviews within 48 hours of admission for patients or 72 hours for proxies.

SETTING

813-bed urban teaching hospital.

PARTICIPANTS

240 patients, mean age 83.8 years, at moderate to high risk for functional decline during hospitalization, admitted from the emergency room to a general medical unit.

MEASUREMENTS

Delays starting or interruptions continuing interviews; patient and environmental conditions potentially affecting data quality; and information on proxy use.

RESULTS

Timely access to patients or proxies was a major difficulty, resulting in the screening of only 53.1% of 867 potentially eligible patients. Multiple patient contacts and visits were required to complete interviews. Only 61.3% of baseline and 28.1% of follow-up interviews were completed on the initial day of contact. Despite having on-site interviewers 7 days a week, 29% of discharge interviews were conducted by telephone. Interviews were >90% complete in 487 of 503 of encounters (97%). Baseline delays and interruptions were usually due to the presence of medical staff, off-unit tests, patient illness, nurse unavailability for interview, and need for a proxy. Most in-hospital interviews were conducted with others present. Proxies were required for approximately one-third of patients at all three interviews.

CONCLUSION

Conducting clinical research with older adults in the current inpatient setting, where patients are more severely ill yet have shorter lengths of stay now than in the past, proves a challenging yet achievable goal. Effective procedures for negotiating the acute care environment are critical to successful studies.

Dejerine-Sottas disease with sensorineural hearing loss, nystagmus, and peripheral facial nerve weakness: de novo dominant point mutation of the PMP22 gene

A 32 year old woman with Dejerine-Sottas disease and negative family history is reported. Clinical onset of her condition was with congenital weakness of her distal four extremities, accompanied by peripheral facial nerve weakness, deafness, and nystagmus. She has used a wheelchair all her life. Sural nerve biopsy showed proliferation of Schwann cells, extensive endoneural fibrosis, axon loss, and demyelination. MNCVs showed marked slowing. MRI of the brain was normal. Molecular genetic studies indicated a de novo dominant missense point mutation of exon 3 of the peripheral myelin protein 22 gene at nucleotide 264 causing replacement of serine with leucine.

Pseudochoreoathetosis. Movements associated with loss of proprioception

OBJECTIVE

To describe seven patients with proprioceptive sensory loss and choreoathetoid movements.

DESIGN

Case series.

SETTING

Outpatient and inpatient university referral.

PATIENTS

Patients with sensory loss and abnormal movements.

INTERVENTION

None.

MAIN OUTCOME MEASURE

None.

RESULTS

One patient had a parietal cortex injury, one had a thalamic infarction, two had spinal cord lesions, two had dorsal root ganglion neuronopathies, and one had an ulnar neuropathy. In each case, the duration of abnormal movements correlated with the duration of proprioceptive sensory loss, and the abnormal movements were restricted to body parts with proprioceptive sensory loss. The movements varied from chorea and athetosis to dystonia.

CONCLUSIONS

These cases suggest that proprioceptive sensory loss can lead to a movement disorder, termed pseudochoreoathetosis, which occurs following the appearance of lesions anywhere along proprioceptive sensory pathways, from peripheral nerves to the cerebral cortex. It is hypothesized that pseudochoreoathetosis occurs because of the failure to process limb proprioceptive information in the striatum. Therefore, both choreoathetosis and pseudochoreoathetosis may be manifestations of the failure of the striatum to properly integrate cortical motor and sensory inputs.

Binder's syndrome (nasomaxillary dysplasia): an uncommonly common disorder

Binder's syndrome or nasomaxillary dysplasia is a disorder characterized by hypoplastic development of the midportion of the midfacial skeleton and its associated soft tissue manifestations. The disorder is probably more common than initially believed with only 40 cases described previous to 1980. However, since 1980, 127 cases have been reported. One case of Binder's syndrome treated with onlay split cranial (calvarial) bone grafts is presented. The technique of using split calvarial bone grafts has become increasingly popular in craniofacial surgery and facial trauma reconstruction. A literature review of Binder's syndrome is outlined and the technique of using split calvarial bone grafts is described. An analysis of the skeleton and soft tissue characteristics of Binder's syndrome is detailed and treatment options discussed.

Temporomandibular joint dysfunction: evaluation and treatment

Temporomandibular joint dysfunction is a complicated problem requiring interdisciplinary cooperation for diagnosis and treatment. Functional problems including bruxism and psychological disorders frequently occur with joint dysfunction making evaluation more difficult. Many new diagnostic modalities are now available to supplement the history and physical examination to provide an accurate assessment of the joint. Although conservative treatment is successful in a majority of the patients, some form of surgical treatment remains the only option for those who do not respond to conservative management. We have discussed the etiology, diagnosis, and treatment of the pathological conditions of the TMJ and introduced a new modality of treatment, temporalis fascia interpositional arthroplasty. Further work is necessary to elucidate the etiology of TMJ dysfunction and develop treatment modalities that avoid the use of alloplastic materials.

Cell-mediated immunity in the uremic rat

The popliteal node assay of the graft-versus-host reaction in the inbred rat provides a sensitive measure of cell-mediated immunity. Spleen cells from uremic Lewis rats as well as normal cells cultured in uremic serum demonstrated significant immunosuppression which was proportional to the severity of the uremia.
