RESUMEN

There are experimental data which suggest that the primary immune effector cell responsible for maintaining immune surveillance against the outgrowth of EBV-transformed B cells in humans is the CTL, but in vivo proof of this is lacking. In this study we perform a series of cellular and molecular assays to characterize an autologous, endogenous immune response against a transplantation-associated, monoclonal, EBV+ posttransplant lymphoproliferative disorder (PTLD). Following allogeneic bone marrow transplantation, a patient developed a monoclonal PTLD of donor B cell origin. With a decrease in immune suppression, we document the emergence of endogenous, donor-derived CD3+CD8+ CTLs, followed by regression of the PTLD. The TCR Vbeta repertoire went from a polyclonal pattern prior to the development of PTLD to a restricted TCR Vbeta pattern during the outgrowth and regression of PTLD. Donor-derived CD3+CD8+ T lymphocytes displayed MHC class I-restricted cytolytic activity against the autologous EBV+ B cells ex vivo without additional in vitro sensitization. The striking temporal relationship between the endogenous expansion of a TCR Vbeta-restricted, CD3+CD8+ population of MHC class I-restricted CTL, and the regression of an autologous monoclonal PTLD, provides direct evidence in humans that endogenous CD3+CD8+ CTLs can be responsible for effective immune surveillance against malignant transformation of EBV+ B cells.

RESUMEN

This article evaluates the relationship of social support to smoking cessation and continued abstinence of 3923 men and women with mild to moderate airway obstruction in the Lung Health Study. At both the end of a 12-week group program and after 1 year, men but not women who were supported in quitting were more likely to be successful. Married status facilitated quitting but was less strongly related to long-term abstinence. Participants supported by an ex-smoker who had attended the group program with them were very likely not smoking after 1 year (men, 74.7%; women, 72.4%). Participants supported by a smoker were less than half as likely to have achieved abstinence after 1 year but still had cessation rates greater than 30%. The nature of these relationships has implications for the distinction between women and men in studies of social support and for intervention strategies. Support people should be included in cessation intervention programs. Spouse involvement, however, is more evidently useful for men than for women.

RESUMEN

The extent and predictors of weight change were assessed among sustained nonsmoking special intervention participants in the Lung Health Study. The intervention included a 12-session group program and 2-mg nicotine gum. At 12 months, female sustained quitters (SQs; n = 248) had gained a mean of 8.4% (5.3 kg) of their baseline weight, whereas male SQs (n = 443) had gained 6.7% (5.5 kg). By 24 months, female SQs had gained 9.8% of their baseline weight compared with 6.9% for men. Nicotine gum usage delayed a portion of the weight gain. Multiple regression analysis showed that weight gain at 12 months was associated with a higher baseline salivary cotinine level, a lower baseline body mass index, drinking less alcohol per week, and a lower cotinine level at 12 months (indicating less or no nicotine gum use). We conclude that moderate weight gain is a long-term consequence of smoking cessation--a portion of which can be delayed with 2-mg nicotine gum.

RESUMEN

Increasing numbers of patients are undergoing diagnostic catheterization as outpatients; however, a small proportion of patients requires hospital admission following the procedure. Unplanned admissions after consecutive outpatient cardiac catheterizations performed during 1 year were prospectively reviewed to determine the incidence of and reasons for admission. Among 847 patients undergoing outpatient cardiac catheterization, 130 patients (15%) required hospital admission after the procedure. Admitted patients were divided into four groups: patients undergoing immediate percutaneous transluminal coronary angioplasty (PTCA) (Group 1; 33%), patients with severe cardiac disease requiring urgent intervention (Group 2; 48%), patients suffering complications or hemodynamic instability (Group 3; 15%), and patients whose procedures were completed too late to allow same-day discharge (Group 4; 4%). Patients over 65 were more likely to require admission and women were more likely to be admitted with complications or hemodynamic instability. Findings are compared with results of other outpatient series, and implications regarding appropriate setting for outpatient catheterization are discussed.

RESUMEN

Of 3,923 special intervention participants in the Lung Health Study who were offered nicotine gum to help them quit smoking, 1,080 (28.9%) were using nicotine gum 12 months after entry into the study. This group is comprised of 33.6% sustained nonsmokers, 54.5% intermittent smokers, and 19.2% continuing smokers. The average use of gum at 12 months is 7.3 pieces per day. At 12 months, men were significantly more likely to be nonsmokers than women, but women were significantly more likely to use gum than men. Among the sustained nonsmokers, continuous gum users reported significantly more mild side effects than those who used gum intermittently, although there were no differences in moderate or severe side effects between the two groups. Overall, the rate of observed side effects was small. Factors associated with nicotine dependence were related to the use and amount of gum use at 12 months.

RESUMEN

Health education programs developed in academic medical centers are not optimally disseminated to community clinical settings. Strategies are needed to translate the findings of research on health education programs into programs useful in a wide range of health care settings. Focus group techniques were used to provide data for revising a successful university-based asthma self-management program to make it more practical for use by community physicians. Physicians representing a variety of specialties attended the sessions and provided feedback on the utility of various components of the original program. The discussions revealed that many physicians felt they did not have the time or resources to conduct the original program and identified elements viewed as impractical. This physician input contributed significantly to the development of a revised program with a briefer, less costly intervention. The revised program was later evaluated by focus group participants. Eighty-eight percent of those who evaluated the revised program agreed they would be able and willing to use the program in their own practices. As a formative evaluation tool, the focus group technique made available useful information that would have been difficult to obtain through evaluation forms alone.

RESUMEN

While medical treatment of COPD has advanced, the failure to adhere to regimens for medication poses a significant barrier to effective management. Furthermore, no data are available regarding adherence for patients within the United States. Data from this investigation indicate that 78 outpatients from a medical center in the southeastern region of the United States were prescribed an average of 6.26 medications with both various dosing schedules and different modes of administration. Adherence was poor, with 42 patients (54 percent) underutilizing medications, 39 patients (50 percent) overutilizing medications during periods of respiratory distress, and 24 patients (31 percent) employing ineffective inhaler dosing techniques. Prescription patterns and adherence were not associated with demographic variables; however, adherence was related to classes of medication and situational variables.

RESUMEN

This study provides an evaluation of the effectiveness of methods to increase handwashing (HW) by nurses working in an intensive care unit. After baseline observations, two interventions were implemented in sequence: three series of classes conducted by the infection control nurse (ICN); and feedback to staff about handwashing errors on the previous day. Staff were aware that handwashing was being observed throughout the study. The educational intervention produced an immediate increase in HW that was followed by a decline to baseline rates over four weeks. Feedback produced an improvement to 97% compliance that was sustained until completion of the study. Improvement in HW compliance following specified critical procedures was also observed following interventions.

RESUMEN

Associations between self-reported average daily alcohol intake and blood pressure were assessed in 5031 black and white men and women ages 18-30 from the Coronary Artery Risk Development in Young Adults Study (CARDIA). In general, intake was positively but weakly related to both systolic and diastolic blood pressure. Associations with systolic pressure were generally stronger than those with diastolic pressure. With average daily alcohol intake categorized as none, 0.1-9.9 ml, 10.0-19.9 ml, 20.0-29.9 ml, and 30.0+ ml, mean systolic pressure, adjusted for age, body mass index, education, smoking, and physical activity, increased progressively with increasing intake in black and white men and in white women. Mean diastolic pressure increased progressively with increasing intake only in white men and women, but was highest for those averaging 30.0+ ml per day in black women as well as white men and women. Mean pressures were also compared for those averaging 75.0+ ml per day (men) or 50.0+ ml per day (women) vs those reporting no intake. Differences in adjusted mean pressures for white men were 3.2 mmHg (95% confidence limits (CL) -0.3, 6.8) for systolic pressure and 1.7 mmHg (-1.6, 5.0) for diastolic pressure. In black men differences were 4.4 mmHg (1.4, 7.4) and 3.4 mmHg (0.6, 6.3), respectively. Differences in white women were 1.4 mmHg (-2.5, 5.3) for systolic pressure and 0.9 mmHg (-2.7, 4.5) for diastolic pressure and for black women, -0.2 mmHg (-4.3, 3.8) and 1.9 mmHg (-1.9, 5.8). Separate analyses in smokers and nonsmokers of the associations between alcohol intake and blood pressure suggested that associations may differ by smoking status in some sex-race groups.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Previous studies have been inconclusive as to whether peak flow meter use teaches asthma patients to better perceive their own pulmonary functioning. This investigation utilized a delayed baseline design to determine if pulmonary awareness could be improved among a sample of 24 adult patients who compared daily peak expiratory flow rates (PEFR) with asthma symptom ratings. Results indicated that among this sample of adult patients: (i) perception of pulmonary functioning was poor, (ii) adherence to peak flow meter use was poor, and (iii) among patients who use peak flow meters daily, self-perception of pulmonary functioning did not improve significantly. Summary tables and descriptive statistics for pulmonary functioning are provided, and treatment implications are discussed.

RESUMEN

Thirty-two asymptomatic college females were assessed on multiple aspects of body image. Subjects' estimation of the size of three body sites (waist, hips, thighs) was affected by instructional protocol. Emotional ratings, based on how they "felt" about their body, elicited ratings that were larger than actual and ideal size measures. Size ratings based on rational instructions were no different from actual sizes, but were larger than ideal ratings. There were no differences between actual and ideal sizes. The results are discussed with regard to methodological issues involved in body image research. In addition, a working hypothesis that differentiates affective/emotional from cognitive/rational aspects of body size estimation is offered to complement current theories of body image. Implications of the findings for the understanding of body image and its relationship to eating disorders are discussed.

RESUMEN

The Asthma Opinion Survey, a 33-item Likert-type instrument, was designed to measure attitudes relevant to self-management in adult outpatients. Items fall into eleven clusters; General Vulnerability, Specific Vulnerability, Attitudes Toward Patient Knowledge, Recognition of Airway Obstruction, Accessibility of Health Care, Panic-Fear, Belief in Treatment Efficacy, Staff-Patient Relationships, Sense of Control, Personal Impact, and Social Impact. Factor analysis of the clusters yielded three factors Vulnerability, Perceived Quality of Care, and Recognition and Control. The items, clusters, and factors all had adequate to good score spreads and internal consistencies. Asthma opinions covaried significantly with demographic characteristics, asthma severity, and intensity of health care utilization, and correlated with the Asthma Symptoms Checklist, an instrument developed at the National Jewish Hospital-National Asthma Center, in ways supporting construct validity. These results suggest the Asthma Opinion Survey is achieving its intended purpose.

RESUMEN

Changes in self-reported pain ratings were assessed in 95 chronic pain patients from data collected at three times: pretreatment evaluation, initial days of treatment and final days of treatment. These data were collected separately for regular, sporadic and nonusers of narcotic medication. Each patient completed a four-week interdisciplinary behaviorally based noninvasive treatment program. There was an average decrease of 7% in self-reported pain ratings between evaluation and the onset of treatment for the three groups. An additional decrease of 21%, 16% and 10% for the sporadic, nonusers and regular users of narcotics respectively was noted during treatment. Statistical analysis revealed a significant decrease in pain ratings across assessment phases but not between groups. Sporadic users of narcotics showed a pattern more similar to nonusers than to the regular users.

RESUMEN

A 53-year-old woman with chronic back pain manifesting urinary frequency and incomplete voiding, presumably due to epidural scarring, was treated with standard TENS. Magnitude of residual urine and urinary frequency were decreased to acceptable limits and maintained in the absence of TENS treatment, allowing discontinuance of daily catheterization.

RESUMEN

Hospital records from 40 back pain patients in private rooms and 40 back pain patients in semi-private rooms were reviewed to determine: (a) if patients in private rooms used more narcotics than patients in semi-private rooms; and (b) whether room type was a predictive variable for narcotic utilization. Patients in private rooms were found to be more likely to use intramuscular request-contingent narcotics than similar patients in semi-private rooms. No differences in the amount of narcotics were observed for other categories of narcotic analgesics. Room type, relevant medical, and demographic variables failed to account for this difference in medication utilization, suggesting that other factors such as medical staff and patient personality variables may be playing an important role in contributing to the use of narcotic analgesics by back-pain patients.
