Cardiac and pulmonary toxicity in patients undergoing high-dose chemotherapy for lymphoma and breast cancer: prognostic factors.

We sought to define risk factors predisposing breast cancer and lymphoma patients to cardiac and pulmonary toxicity when undergoing high-dose chemotherapy (HDC) and autologous stem cell rescue (ASCR). Additionally, we evaluated in depth the predictive value of the ejection fraction measured prior to HDC in determining cardiac toxicity. In this retrospective analysis, 24 variables were examined in 138 patients undergoing HDC and ASCR from 1990 until 1995. Logistic regression models were used to model the probability of experiencing cardiac and pulmonary toxicity as a function of the 24 prognostic covariates. Cardiac toxicity occurred in 12% of patients and pulmonary toxicity in 24% of patients. Bivariate analyses showed that patients with lymphoma (as opposed to breast cancer) and those with a higher cardiac risk factor score were more likely to experience cardiac toxicity. Multivariate logistic regression models predicted lymphoma and older age to be risk factors for cardiac toxicity. History of an abnormal ejection fraction and higher doses of anthracyclines prior to HDC may also contribute to cardiac toxicity. Pulmonary toxicity occurred more commonly in lymphoma than breast cancer patients, likely due to the busulfan used in the HDC regimen. No other risk factors for pulmonary toxicity were identified. We conclude that older patients with lymphoma should be carefully evaluated prior to being accepted for HDC programs. Older patients with breast cancer may tolerate this procedure well. There is a trend towards cardiac toxicity in patients with a past history of low ejection fraction, although seemingly poor cardiac risk patients may fare well with HDC if carefully selected with the aid of a thorough cardiac evaluation.

Alcohol education in licensed premises using brief intervention strategies.

AIMS: The aim of this feasibility study is to present a description of a new approach based on alcohol brief intervention strategies to intervene with at-risk drinkers in licensed premises. DESIGN: The data presented are from a convenience sample of tavern patrons. SETTING: The intervention called Operation Drinksafe was conducted on 75 occasions in 67 licensed premises in an Australian rural area. PARTICIPANTS: There were 2761 voluntary participants who were provided with a personal risk assessment of their alcohol use. MEASUREMENTS: The main measurements were the Alcohol Use Disorders Identification Test (AUDIT) combined with a blood alcohol concentration (BAC) reading. FINDINGS: The median AUDIT score was 11.0, with 53% scoring in the hazardous range and 25% in the harmful range. For binge drinking, almost two-thirds (62%) of males drank six or more drinks once a week or more compared to 29% of females. Median BAC was 0.03 mg/100 ml with 11% of males above 0.10. Regression analysis revealed that significant predictors of alcohol-related injury were being aged less than 30 years, forgetting the previous night, having had another person express concern about your drinking, and binge drinking weekly or more. CONCLUSIONS: The program had high acceptance among licensees and their patrons. Patrons who are ready to change their at-risk drinking behaviour may benefit from this type of minimal intervention when presented in an interesting way in their drinking environments.

The strengths perspective of case management: a promising inpatient substance abuse treatment enhancement.

The medical model or disease concept approach to substance abuse treatment is practiced in most residential substance abuse treatment programs. Despite wide acceptance, many of the factors inherent in this approach may actually increase patient noncompliance with treatment regimens. These factors are related to the pathology-based nature of substance abuse treatment, an overemphasis on patient denial, and the paternalistic role that treatment staff often take in the treatment of substance abusers. The Strengths Perspective of Case Management/Advocacy has demonstrated usefulness as an adjunct to treatment that remedies these detrimental factors and improves compliance with, and retention in, treatment. The specific activities that lead to this improvement are discussed.

Dysphonia and laryngeal sequelae in paracoccidioidomycosis patients: a morphological and phoniatric study.

The larynx is the third most commonly involved organ in paracoccidioidomycosis (PCM). While a few studies have evaluated laryngeal sequelae, there have not been any investigations of voice abnormalities in PCM patients. To evaluate persistent dysphonia and laryngeal lesions, we studied 15 normal subjects and 30 post-treatment PCM patients, i.e., 15 with only pulmonary and 15 with both laryngeal and pulmonary involvement. Perceptual and acoustic voice analysis were performed with all patients, while endoscopic studies were also conducted with the 15 laryngeal patients. Voice analysis showed instability by perceptual analysis (P<0.01) in both groups, but more severe dysphonia was noted in the laryngeal group (P<0.01). The dysponia, seen in 66.7% of these patients (dysphonia index < 7.0), was characterized by roughness and breathness. The Dr. Speech (Tiger Electronics) analysis program did not accept five voices from the laryngeal group due to the severe dysphonia. Jitter was elevated in five laryngeal lesion patients. Endoscopy showed that 80% of patients with laryngeal lesion had two or more laryngeal structures involved. Vocal fold alterations were seen in all laryngeal lesion patients, which included involvement of the arythenoids, epiglottis, and vestibular folds. This first functional study of laryngeal sequelae in PCM revealed frequent and severe dysphonia that may have important social consequences for patients.

Vaccine preferences and their role for vaccine confidence and uptake: a meta-ethnography.

Vaccine confidence and uptake are influenced by individuals' preferences regarding vaccine composition, quality, or administration pathways. However, literature synthesizing available qualitative insights into individuals' vaccine preferences remains limited. We therefore conducted a meta-ethnographic systematic review of the qualitative literature on vaccine preferences to identify opportunities for enhancing vaccine confidence and uptake. We implemented a comprehensive search strategy and screened 5,528 studies across seven research databases published between 2001 and 2023. We identified and synthesized 97 qualitative articles to delineate factors influencing consumers' vaccine preferences. Our findings revealed four primary domains shaping individuals' vaccine preferences: Product, Place, Price, and Promotion. First, individuals' preferences for vaccines often hinge on perceived quality and safety of the product itself, which can, for example, be associated with vaccine brand or origin, especially in the case of novel vaccines. Second, people prioritize convenience in terms of vaccination sites and delivery methods (wanting vaccinations offered at their doorstep or in local peripheral clinics); evidence regarding preferred groups to administer the vaccines was mixed. Third, the price of vaccines and the secondary costs associated with vaccination played a role in uptake considerations. Finally, both the sources of information (such as healthcare workers, community volunteers, and religious authorities) and the methods of promoting vaccine information (including face-to-face consultations during clinic visits and the distribution of leaflets or banners), emerged as crucial factors shaping decision-making processes. Overall findings highlight the importance of addressing multifaceted preferences to enhance vaccine confidence and uptake. By understanding individuals' vaccine preferences, strategic recommendations can be developed to optimize vaccination programs and ensure acceptability and utilization.

Screening Jews and genes: a consideration of the ethics of genetic screening within the Jewish community: challenges and responses.

Screening for genetic disorders, particularly Tay-Sachs Disease, has been traditionally welcome by the Jewish community. I review the history of genetic screening among Jews and the views from the Jewish tradition on the subject, and then discuss ethical challenges of screening and the impact of historical memories upon future acceptance of screening programs. Some rational principles to guide future design of genetic screening programs among Jews are proposed.

Selecting patients for heart transplantation: which patients are too well for transplant?

In the context of contemporary medical and surgical therapy, the revolutionary procedure of cardiac transplantation should be redefined in its relative role. Based on the assumption that its goal is to prolong life while improving its quality, and in the absence of randomized clinical trial data testing its benefit, data from early breakthrough studies, more recent observational cohort studies, and studies testing other therapies in advanced heart failure must be analyzed to characterize clinical profiles of patients who should be considered too well for cardiac transplantation at specific stages of their disease processes. These profiles likely include advanced heart failure with (1) low risk according to the Heart Failure Survival Score, (2) peak oxygen consumption greater than 14 to 18 mL/kg/min without other indications, (3) left ventricular ejection fraction less than 20% alone, (4) history of New York Heart Association class III to IV symptoms alone, (5) history of ventricular arrhythmias alone, (6) no previous attempt at comprehensive neurohormonal blockade, and (7) no structured cardiac transplantation evaluation in a designated cardiac transplantation center. The evaluation may identify the potential transplant candidate, who could be placed on a national potential transplant candidate list, combining the psychologic benefit of acceptance by the program with an ongoing openness to the diversity of advanced heart failure treatment modalities.

Technology management: a perspective on system support, procurement, and replacement planning.

The escalating costs associated with medical technology present a host of challenges for the hospital clinical engineering department. As service and support costs comprise ever larger portions of a system's life cycle cost, innovative management of service provider mix and mechanisms can provide substantial savings in operating expenses. In addition to full-service contracts, the use of demand service and independents has become commonplace. Medical equipment maintenance insurance programs provide yet another service alternative, combining the flexibility of demand service with the safety of a capped budget. These programs have gained acceptance among hospitals as their providers have become more focused on the healthcare market and its many needs. In view of the long-term cost impact surrounding technology procurement, the authors recommend that hospitals refine system evaluation methodologies and develop more comprehensive techniques directed at capital equipment replacement planning. One replacement planning approach, based on an estimation of system value changes, is described and illustrated using data collected through client consultations. Although the validity of this method has not been demonstrated, it represents a simplified approach to life cycle cost analysis and is intended to provide a standard method by which system replacement planning may be quantified. As a departure from system devaluation based solely on depreciation, this method estimates prospective system values derived from anticipated operations and maintenance costs, projected revenue, and the availability of new technology.

Surveillance, social risk, and symbolism: framing the analysis for research and policy.

Name-based surveillance for HIV, considered alone, is a useful public health measure; its benefits outweigh its direct costs. There is little evidence that name-based surveillance directly deters individuals at risk of HIV from being tested, or exposes them to significant social risks. Yet such surveillance is chronically controversial. Understood in a broader context of the social risks and symbolic politics of HIV, as subjectively experienced by people at risk, this opposition is both rational and instructive. Although often discussed, the social risks of HIV infection are poorly understood. To the extent these risks have been addressed by privacy and antidiscrimination laws, the solution has been less complete than many public health professionals appear to believe: developments in law and policy, including the increasing prevalence of criminal HIV transmission laws and proposed changes in HIV testing and counseling standards, are contextual factors that help explain the opposition to name-based surveillance. Rather than focusing piecemeal on specific "barriers" to testing and care, an appreciation of the surveillance debate in context suggests a positive undertaking in public health policy to provide the conditions of opportunity, information, motivation and confidence that people with HIV need to accept an effective program of early intervention.

Cost-effectiveness of a school-based Tay-Sachs and cystic fibrosis genetic carrier screening program.

PURPOSE: To explore the cost-effectiveness of school-based multi-disease genetic carrier screening. METHOD: Decision analysis of the cost-effectiveness of a school-based Tay-Sachs disease and cystic fibrosis genetic carrier screening program, relative to no screening. Data relating to ethnicity profile, test-accepting behavior, and screening program cost were sourced from an existing program in Sydney, Australia. RESULTS: Compared to no screening, the incremental cost-effectiveness of the screening program is A dollar 5,834 per additional carrier detected. This cost-effectiveness ratio is most sensitive to changes in genetic test accuracy, and the cost of laboratory assays. The results imply a cost per affected birth avoided of approximately A dollar 530,000 (approximately US dollar 371,000). CONCLUSIONS: This preconceptional genetic carrier screening program offers comparable cost-effectiveness to prenatal screening programs for cystic fibrosis.

Neuroscience nursing elective for senior nursing students.

In response to baccalaureate student requests for additional clinical experience and expanded opportunities in neurological and neurosurgical nursing, an experimental course was designed for the winter session semester in cooperation with a local teaching hospital. A three-credit elective, "Discovering Neuroscience Nursing," was offered to senior students for five weeks. The course included thirty hours of lecture and laboratory, field trips, and over 200 hours of clinical experience. A student stipend was provided by the hospital. Goals for the course centered on providing an opportunity for the student to gain competence and confidence in caring for patients with neurological dysfunctions and providing family support. Students were assigned staff nurse preceptors as they rotated to every clinical setting caring for patients with alterations to the nervous system. Evaluations from students and staff preceptors indicated the successful acceptance of the program which will be modified and continued as a senior elective.

Broadening the understanding of injury prevention: a case study.

The death or injury of a loved one is tragic, especially if that injury could have been prevented. Programs to reduce the incidence and severity of neurological trauma are traditionally driven by injury statistics, and the literature on neurological injury prevention often fails to capture individual experiences. Understanding community members' concerns about injury and safety efforts can move injury-prevention programs to a new level by assessing injury-related beliefs and refining interventions suited to the community. Pediatric injury is an especially complex problem that is influenced by developmental, environmental, sociopolitical, economic, geographic, parental, and child-related factors. Recognition of injury as a public health concern supports updating program development. The following case study, based on an in-depth parent interview, offers a unique perspective on pediatric injury. The audiotaped interview was transcribed verbatim following qualitative guidelines. Three main themes emerged from the analysis: (a) sources of parental concern for children's safety, (b) private versus public safety influences, and (c) behaviors making children vulnerable to injury. As this case study illustrates, parents may consider children susceptible to injury as a result of factors often not considered by injury prevention programs, for example, being "injury prone." Parents also have access to resources, grandparents, for example, not typically considered when programs are marketed. The challenge is to identify how programs become an accepted public safety influence and to address real-life parental concerns.

Periodontal self-examination. A motivational tool in periodontics.

The institution of proper oral hygiene procedures and habits is a learning process. This paper describes a self-instructing periodontal self-examination program to be used in the initial phase of periodontal treatment. The program was designed in an effort to facilitate learning by taking the teaching conditions into consideration. The program tries to utilize the patient's curiosity and need for activity and to involve the patient himself in an effort to make the patient apprehend the relevance of subject matter. The program also allows for an individualized learning speed of the patient. The self-examination program was tested on 108 periodontal patients (19-75 years of age) and the patients' findings were compared to those made by a dentist. Questionnaires before and after the self-examination were used in the evaluation of opinions of the patient. The present study showed that the patients were able to perform the self-examination without individual professional guidance. A rather close correlation was noted between findings made by the patient and the dentist. Furthermore, the program was well accepted and appreciated by the patients according to their answers on the questionnaires.

Practice Audit in Gastroenterology (PAGE) program: a novel approach to continuing professional development.

BACKGROUND: Practice audit is an important component of continuing professional development that may more readily be undertaken if it were less complex. This qualitative study assessed the use of personal digital assistants to facilitate data collection and review. METHODS: Personal digital assistants programmed with standard questionnaires related to upper gastrointestinal endoscopies (Practice Audit in Gastroenterology-Endoscopy ['PAGE-Endo']) and colonoscopies (PAGE-Colonoscopy ['PAGE-Colo']) were provided to Canadian gastroenterologists, surgeons and internists. Over a three-week audit period, participants recorded indications, and the expected (E) and reported (R) findings for each procedure. Thereafter, participants recorded compliance with reporting, the ease of use and value of the PAGE program, and their willingness to perform another audit. RESULTS: Over 15 to 18 months, 173 participants completed PAGE-Endo (6168 procedures) and 111 completed PAGE-Colo (4776 procedures). Most respondents noted that PAGE was easy to use (99%), beneficial (88% to 95%), and that they were willing undertake another audit (92% to 95%). In PAGE-Endo, alarm features were prevalent (55%), but major reported findings were less common than expected: esophagitis (E 29.9%, R 14.8%), esophageal stricture (E 8.3%, R 3.6%), gastric ulcer (E 17.0%, R 4.7%), gastric cancer (E 4.3%, R 1.0%) and duodenal ulcer (E 11.5%, R 5.7%). In PAGE-Colo, more colonoscopies were performed for symptom investigation (55%) than for screening (25%) or surveillance (20%). There were marked interprovincial variations with respect to sedation, biopsies and technical aspects of colonoscopy. CONCLUSION: Secure, real-time data entry with review of aggregate and individual data in the PAGE program provided an acceptable, straightforward methodology for accredited practice audit activities. PAGE has considerable potential for continuing professional development in gastroenterology and other specialties.

The relationship between maximal expiratory flow and increases of maximal exercise capacity with exercise training.

We previously reported that patients with mild to moderate airflow limitation have a lower exercise capacity than age-matched controls with normal lung function, but the mechanism of this reduction remains unclear (1). Although the reduced exercise capacity appeared consistent with deconditioning, the patients had altered breathing mechanics during exercise, which raised the possibility that the reduced exercise capacity and the altered breathing mechanics may have been causally related. Reversal of reduced exercise capacity by an adequate exercise training program is generally accepted as evidence of deconditioning as the cause of the reduced exercise capacity. We studied 11 asymptomatic volunteer subjects (58 +/- 8 yr of age [mean +/- SD]) selected to have a range of lung function (FEV1 from 61 to 114% predicted, with a mean of 90 +/- 18% predicted). Only one subject had an FEV1 of less than 70% predicted. Gas exchange and lung mechanics were measured during both steady-state and maximal exercise before and after training for 30 min/d on 3 d/wk for 10 wk, beginning at the steady-state workload previously determined to be the maximum steady-state exercise level that subjects could sustain for 30 min without exceeding 90% of their observed maximal heart rate (HR). The training workload was increased if the subject's HR decreased during the training period. After 10 wk, subjects performed another steady-state exercise test at the initial pretraining level, and another maximal exercise test. HR decreased significantly between the first and second steady-state exercise tests (p < 0.05), and maximal oxygen uptake (VO2max) and ventilation increased significantly (p < 0.05) during the incremental test, indicating a training effect. However, the training effect did not occur in all subjects. Relationships between exercise parameters and lung function were examined by regression against FEV1 expressed as percent predicted. There was a significant positive correlation between VO2max percent predicted and FEV1 percent predicted (p < 0.02), and a negative correlation between FEV1 and end-expiratory lung volume (EELV) at maximal exercise (p < 0.03). There was no significant correlation between FEV1 and maximal HR achieved during exercise; moreover, all subjects achieved a maximal HR in excess of 80% predicted, suggesting a cardiovascular limitation to exercise. These data do not support the hypothesis that the lower initial VO2max in the subjects with a reduced FEV1 was due to deconditioning. Although increased EELV at maximal exercise, reduced VO2max and a reduced VO2max response with training are all statistically associated with a reduced FEV1, there is no direct evidence of causality.
