A concept analysis of dignity for older adults.

BACKGROUND: Human dignity is an essential value of professional nursing education as well as a component of the American Nurses Association Code of Ethics. Nurses are exhorted to treat patients with dignity, and older adults want to be treated with dignity and die with dignity. Although dignity, particularly the dignity of older adults, is often discussed in the health care literature, its meaning is not always clear. AIM: The aim of this paper is to describe a concept analysis to develop a definition of dignity in older adults. METHODS: Data were collected using a literature review and five focus groups composed of older adults. The literature provided data about professionals' ideas of dignity and the focus groups provided qualitative data about the nature of dignity in older people. The literature review and focus groups were carried out concurrently, followed by synthesis of the findings. FINDINGS: Dignity is an inherent characteristic of being human, it can be subjectively felt as an attribute of the self, and is made manifest through behaviour that demonstrates respect for self and others. Dignity must be learned, and an individual's dignity is affected by the treatment received from others. CONCLUSIONS: A behavioural definition of dignity was constructed and this could provide the theoretical basis for nurses to develop interventions that foster dignity for older people.

Selective effector mechanisms for the expulsion of intestinal helminths.

In the middle of the era of molecular biology, much less attention is paid to in vivo phenomena. However, carefully designed experimental systems in vivo still can provide valuable information as to the mechanisms underlying the establishment and maintenance of host-parasite relationships. In this review we describe the advantage of using concurrent infections with appropriately chosen combinations of different genera or different maturation stages of parasites to segregate the cellular responses of the host. By means of simple experimental approaches we have found that mucosal mast cells and goblet cells, both of which have long been considered as non-specific effectors, are in fact highly selective and specific effector cells of the host defence mechanisms capable of acting on the establishment and the expulsion of intestinal helminths.

Functional outcome measures to assess interventions for spasticity.

PURPOSE: Clinicians use functional loss as a criterion to treat spasticity, but the connection between function and severity of spasticity is not well established for monitoring spasticity treatment effect. Studies were reviewed which have implemented outcome measures to assess functional changes relative to changes in spasticity. Criteria for review included the reliability and internal validity of the functional measures used and the strengths/weaknesses of the study designs that likely affected the external validity of the measures for this application. Guidelines are provided for the use and development of functional outcome measures in futures studies of spasticity treatment based on this review. DATA IDENTIFICATION: An English-language literature search using MEDLINE and bibliographies of published articles and textbooks was conducted. RESULTS: Very few functional measures demonstrated changes concurrent to a reduction in spasticity. There were multiple potential confounding factors in study protocols, reporting of results, and data analysis that might account for the limited number of measures shown to be valid for this application. Selected standardized ordinal functional outcome scales (the PECS and PEDI) and specific functional tasks were identified as measures that show promise for assessing changes concurrent with altered spasticity level. CONCLUSION: Based on a review of previous studies, functional measures involving posture, positioning, balance, and certain mobility skills have potential, with further test development, to provide needed information regarding the impact of spasticity on functional outcome.

Amiodarone and radiation therapy sequelae.

With the aging of our population, amiodarone, a cardiac antiarrhythmic, is being used with increasing frequency. Anecdotal reports have appeared describing unexpected mucosal as well as cutaneous toxicity in patients treated concurrently with external beam radiotherapy and oral amiodarone. We retrospectively reviewed 12 years of experience at the University of Iowa Hospitals and Clinics and found 10 cases wherein amiodarone was taken concurrently with external beam radiation therapy. In our series, there were no missed treatment fractions because of unexpected acute sequelae. We conclude that amiodarone use does not preclude the delivery of therapeutic radiotherapy.

Highly active antiretroviral therapy (HAART) in adults with tuberculosis: current status.

The overlapping epidemiology of human immunodeficiency virus (HIV) infection and tuberculosis (TB) and the catastrophic consequences of the interactions between the two epidemics have led to increased morbidity and mortality due to HIV-associated TB. While effective therapy is available for both conditions, there are major challenges in the concurrent treatment of HIV and TB co-infection. This review examines the interactions between HIV and TB infections and reviews the current status of highly active antiretroviral therapy (HAART) in patients with co-infection. Specific questions relating to optimal timing of concurrent HAART, challenges to concurrent HAART, optimal regimens and future considerations are discussed.

Congenital toxoplasmosis: systematic review of evidence of efficacy of treatment in pregnancy.

OBJECTIVE: To summarise the evidence that treating toxoplasmosis in pregnancy reduces the risk of congenital toxoplasma infection and improves infant outcomes. DESIGN: Systematic review of studies comparing at least two concurrent groups of pregnant women with proved or likely acute toxoplasma infection in which treatments were compared with no treatment and outcomes in the children were reported. SUBJECTS: Studies were identified from Medline (1966-97), Pascal (1990-7), Embase (1993-7), and Biological abstracts (1993-5) plus contact with experts in the field, including the European Research Network on Congenital Toxoplasmosis. MAIN OUTCOME MEASURE: Proportion of infected children at 1 year born to infected pregnant women who were or were not treated. RESULTS: Out of 2591 papers identified, nine met the inclusion criteria. There were no randomised comparisons, and control groups were generally not directly comparable with the treatment groups. Congenital infection was common in treated groups. five studies showed that treatment was effective and four that it was not. CONCLUSION: It is unclear whether antenatal treatment in women with presumed toxoplasmosis reduces congenital transmission of Toxoplasma gondii. Screening is expensive, so the effects of treatment and impact of screening programmes need to be evaluated. In countries where screening or treatment is not routine, these technologies should not be introduced outside carefully controlled trials.

Monoamine oxidase inhibitors and narcotic analgesics. A critical review of the implications for treatment.

There has been a recent renewal of interest in the use of monoamine oxidase inhibitors, but the concurrent administration of narcotic analgesics is often a cause for concern. This review clarifies the different types of MAOI/narcotic interactions and offers guidelines for the use of narcotic analgesics in the presence of MAOIs. The MAOI/pethidine interaction has two distinct forms: an excitatory and a depressive form. Pethidine must never be used in the presence of MAOIs because of the risk of a fatal excitatory interaction. Morphine does not cause this excitatory interaction, and is the drug of choice provided an allowance is made for possible potentiation of the depressive narcotic effect. It is inevitable that strong analgesia will occasionally be required as an emergency measure in patients on MAOIs, and insufficient attention is paid in psychiatric textbooks to the two different types of interactions and their therapeutic implications.

Adverse drug reaction reporting system: developing a well-monitored program.

The spontaneous reporting of adverse drug reactions (ADRs) at the St. John's Hospital and Memorial Medical Center was well below that reported in the literature. After review of procedures for reporting of ADRs at these institutions, the authors developed a system that was approved by their joint P & T Committee. The ADR reporting program developed uses concurrent monitoring of most hospital inpatients and a retrospective review of all emergency room patients. In the year after program implementation, 162 ADR reports were documented. From this program, a group of serious ADRs to one agent was identified and reported, both to the Food and Drug Administration and to the manufacturer. A well-developed ADR monitoring program may lead to heightened physician and nurse awareness and early problem identification, possibly decreasing morbidity for hospitalized patients.

Communicating with patients with inflammatory bowel disease.

Ulcerative colitis and Crohn's disease, the two main forms of inflammatory bowel disease (IBD), are chronic illnesses that affect hundreds of thousands of Americans. Patients with IBD suffer chronically from diarrhea, abdominal pain, gastrointestinal bleeding, malabsorption, and weight loss requiring continuous medical and surgical attention. Despite recent advances in therapy, IBD follows a course of exacerbations and remissions with approximately 25-50% of patients relapsing annually. Hence, these diseases are readily encountered in primary care and gastroenterology clinics. Though medical and surgical treatment options have improved significantly, little has been written about the psychosocial aspects of IBD. Currently, there is a paucity of data concerning effective communication methods enabling physicians to develop stronger rapport with patients suffering from IBD, the care of whom requires a multidisciplinary approach involving primary care physicians, gastroenterologists, and colorectal surgeons. Because IBD has a high morbidity, it is worthwhile to further investigate those social factors that will improve patients' quality of life. In this paper, we summarize some of the common problems that emerge when taking care of patients with IBD and provide initial guidelines based on the world literature regarding the management and education of patients with IBD. Both primary care physicians and specialists (gastroenterologists, colorectal surgeons) need to be aware of the questions and concerns of IBD patients and to be capable of dispensing the information in a clear and concise manner. Using the case scenario format, we review the most common aspects of communication for health care professionals taking care of IBD patients and suggest ways to establish and maintain long-term doctor-patient relationships. The two most significant interventions that dramatically improve quality of life and patient-physician relationships are proper patient education and appropriate treatment of concurrent depression and anxiety. We hope that our review will form a framework by which different members of the medical team learn their roles in the complex management decisions affecting IBD patients.

Use of concurrent monitoring and a preprinted note to modify prescribing of i.v. cimetidine and ranitidine in a teaching hospital.

The use of concurrent monitoring and an informational note to modify physician prescribing of i.v. cimetidine and ranitidine is described. The study population consisted of all patients for whom i.v. cimetidine and ranitidine therapy was prescribed by house-staff physicians at an 850-bed, tertiary-care, university-affiliated hospital during February, March, and April 1987. Phase 1 of the trial consisted of an initial drug-use review of all eligible patients receiving therapy. In phase 2, the study population was divided into an intervention group and a control group. When therapy could be changed from the i.v. to the oral or nasogastric (NG) route of administration, an informational note was placed in the chart of the patients in the intervention group. Patients in the control group were also assessed daily for the appropriateness of conversion to oral or NG therapy. The following outcome measures were used to test the effectiveness of the intervention in modifying physician prescribing: mean number of i.v. doses and days of i.v. therapy per patient and mean number of inappropriate i.v. doses and days of i.v. therapy per patient. The drug acquisition costs for both groups were also analyzed. A total of 233 patients were monitored during the study period. The percentage of patients who did not receive oral therapy as soon as possible was not significantly different between the intervention (55%) and control (58%) groups. Patients in the intervention group received three to six fewer i.v. doses than patients in the control group and three to six additional oral doses.(ABSTRACT TRUNCATED AT 250 WORDS)

Concurrent strength and endurance training: from molecules to man.

Strength and endurance training produce widely diversified adaptations, with little overlap between them. Strength training typically results in increases in muscle mass and muscle strength. In contrast, endurance training induces increases in maximal oxygen uptake and metabolic adaptations that lead to an increased exercise capacity. In many sports, a combination of strength and endurance training is required to improve performance, but in some situations when strength and endurance training are performed simultaneously, a potential interference in strength development takes place, making such a combination seemingly incompatible. The phenomenon of concurrent training, or simultaneously training for strength and endurance, was first described in the scientific literature in 1980 by Robert C. Hickson, and although work that followed provided evidence for and against it, the interference effect seems to hold true in specific situations. At the molecular level, there seems to be an explanation for the interference of strength development during concurrent training; it is now clear that different forms of exercise induce antagonistic intracellular signaling mechanisms that, in turn, could have a negative impact on the muscle's adaptive response to this particular form of training. That is, activation of AMPK by endurance exercise may inhibit signaling to the protein-synthesis machinery by inhibiting the activity of mTOR and its downstream targets. The purpose of this review is to briefly describe the problem of concurrent strength and endurance training and to examine new data highlighting potential molecular mechanisms that may help explain the inhibition of strength development when strength and endurance training are performed simultaneously.

On the usefulness of somatosensory evoked responses for the evaluation of lower back pain.

Electrodiagnostic and concurrent computed tomographic (CT) scan data were reviewed from 30 patients with lower back pain and unilateral radicular symptoms. Electrodiagnostic examination included somatosensory evoked responses (SSEPs) of the L-4, L-5, and S-1 roots stimulating specific sensory nerves. In three patients with normal CT scans, electrophysiologic studies were unrevealing. In the remaining 27 patients, CT scans were consistent with root injury, as were 15 of 17 myelograms. In 21 of these 27 patients, SSEP abnormalities consistent with focal root dysfunction and the radiographic findings were present. Other electrodiagnostic abnormalities (ie, electromyographic F response or H reflex) were limited to the six patients with clinical signs. These data indicate that SSEPs are valuable for evaluating root injury in patients with lower back pain, particularly where focal sensorimotor or reflex signs are absent.

Optimization of the peritoneal lavage.

Review of 275 consecutive peritoneal lavages and concurrent histologic material from gynecologic operations suggested that cytologic evaluation was clinically indicated for only 60.7% of the lavages, representing 46% of the patients in the study. More than one concurrent lavage was received from 21.6% of all patients in the study, comprising 50% of patients with malignant lavages, 18.7% of patients with benign lavages, and 5.3% of patients for whom cytologic evaluation of peritoneal lavage was not clinically indicated. Malignant cells were diagnosed in 15% of the 167 lavages for which cytologic examination was clinically indicated. In this series of patients, identification of malignant cells in peritoneal lavages did not increase the tumor stage beyond that obtained solely from examination of the concurrent histologic material. There were no false-positive cytologic diagnoses and no lavages in which neoplastic cells were misinterpreted as benign. A significant number of lavages, including several from patients with histologically confirmed peritoneal tumor, were sparsely cellular and/or excessively bloody. It is suggested that although peritoneal lavages might be collected during all gynecologic operations, only specimens from selected cases should be submitted for cytologic evaluation, and greater attention should be given to specimen collection to ensure that only well-preserved and representative material from the peritoneum is submitted for cytologic evaluation.

Transradial bilateral cardiac catheterization and endomyocardial bioposy: a feasibility study.

A case series and technique of transradial cardiac catheterization with cardiac biospy are described. Transradial cardiac catheterization is perceived to be limited to arterial procedures. Using the veins of the forearm, we have converted many previous femoral arterial/venous cardiac procedures to a transradial/forearm approach. Retrospective review of patients undergoing transradial procedures with concurrent cardiac biopsies was undertaken. A convenience sample of transfemoral procedures with biopsies performed by the same operator was identified for comparison. Coronary angiography/left heart catheterization was performed using standard transradial/femoral approaches. A 7 Fr introducer sheath was placed via a large median forearm or femoral vein. Right heart catheterization was done using a 120 cm balloon-tipped catheter and endomyocardial biopsy was performed with a 7 Fr biotome. Both groups were then compared for baseline characteristics and procedural events. Transradial (n = 8) and transfemoral (n = 12) procedures were all done for postcardiac transplantation management. There was no crossover between groups. Durations of the radial procedures (median, 73 min; range, 40-95) were similar to transfemoral procedures (median, 68 min; range, 45-105). No procedural complications were reported. Endomyocardial biopsy plays an important role in the diagnosis of transplant rejection and identification of pathological processes that cause myocardial dysfunction. Transradial cardiac catheterization has some clear advantages over a transfemoral approach. Bilateral cardiac catheterization with concurrent cardiac biopsy is technically feasible using a transradial/forearm approach. This approach offers an alternative approach for selected patients in need of cardiac biopsy.

The addition of induction chemotherapy to preoperative, concurrent chemoradiotherapy improves tumor response in patients with esophageal adenocarcinoma.

BACKGROUND: Tumor viability assessed by pathologic analysis of resected specimens in patients with preoperatively treated esophageal adenocarcinoma (EAC) is a prognostic indicator. The feasibility of induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) and surgery for patients with locoregionally advanced EAC has been demonstrated. In this study, the authors evaluated the efficacy of CCRT compared with traditional concurrent chemoradiotherapy (CRT). METHODS: The authors retrospectively reviewed 247 consecutive patients with EAC who presented for planned surgery after treatment with either CCRT or CRT from January 1997 through August 2003. Patient demographics, comorbidities, and tumor characteristics were analyzed. Pathologic tumor response, overall survival, and disease-free survival were assessed according to treatment. RESULTS: One hundred seventeen patients received CCRT, and 130 patients received CRT before planned surgical resection. CCRT resulted in a 64% tumor response rate compared with a 51% tumor response rate in the CRT group (odds ratio, 1.73; P = .035). In the CCRT group, the median overall survival was 55 months, and the 3-year overall survival rate was 59%; in the CRT group, the median overall survival was 25 months, and the 3-year overall survival rate was 41% (hazard ratio [HR], 0.69; P = .041). In the CCRT group, the median disease-free survival was 43 months, and the 3-year disease-free survival rate was 54%; in the CRT group, the median disease-free survival was 18 months, and the 3-year disease-free survival rate was 36% (HR, 0.72; P = .047). Subset analysis of patients with clinical Stage III/IVA disease showed a median overall survival of 51 months with a 3-year overall survival rate of 58% in the CCRT group and a median overall survival of 20 months with a 3-year overall survival rate of 28% in the CRT group (HR, 0.57; P = .019). CONCLUSIONS: In patients with EAC, CCRT improved tumor response significantly compared with traditional CRT alone. Overall survival and disease-free survival were increased in patients who received CCRT, especially in the subset of patients who had more advanced disease.

Insulin resistance and monoclonal gammopathy.

Two maturity-onset diabetic patients developed severe insulin resistance during the course of monoclonal gammopathies. One patient had Waldenström macroglobulinemia and the other had multiple myeloma with IgA gammopathy. The maximum insulin binding capacity (MIBC) was 121 U/liter and 54.7 U/liter, respectively, during insulin resistance. The clinical courses of insulin resistance paralleled the activity of the monoclonal gammopathies (MG) with the insulin resistance disappearing after the monoclonal gammopathies were controlled. Six other diabetic patients with concurrent insulin resistance and monoclonal gammopathies are reviewed.
