The determinants of long-term blood pressure stability: control of trough blood pressure during sleep

Little is known regarding the prevalence and course of fatigue in cancer patients after treatment has ended and no recurrence found. The present study examines fatigue in disease-free cancer patients after being treated with radiotherapy (n = 154). The following questions are addressed. First, how do patients describe their fatigue 9 months after radiotherapy and is this different from fatigue in a nonselective sample from the general population (n = 139)? Secondly, to what degree is fatigue in patients associated with sociodemographic, medical, physical and psychological factors? Finally, is it possible to predict which patients will suffer from fatigue 9 months after radiotherapy? Results indicated that fatigue in disease-free cancer patients did not differ significantly from fatigue in the general population. However, for 34% of the patients, fatigue following treatment was worse than anticipated, 39% listed fatigue as one of the three symptoms causing them most distress, 26% of patients worried about their fatigue and patients' overall quality of life was negatively related to fatigue (r = -0.46). Fatigue in disease-free patients was significantly associated with: gender, physical distress, pain rating, sleep quality, functional disability, psychological distress and depression, but not with medical (diagnosis, prognosis, co-morbidity) or treatment-related (target area, total radiation dose, fractionation) variables. The degree of fatigue, functional disability and pain before radiotherapy were the best predictors of fatigue at 9-month follow-up, explaining 30%, 3% and 4% of the variance respectively. These findings are in line with the associations found with fatigue during treatment as reported in the preceding paper in this issue. The significant associations between fatigue and both psychological and physical variables demonstrate the complex aetiology of this symptom in patients and point out the necessity of a multidisciplinary approach for its treatment.     

A monoclonal antibody directed against the non-toxic subunit of a dimeric phospholipase A2 neurotoxin, crotoxin, neutralizes its toxicity

Cancer patients undergoing radiotherapy frequently report fatigue. However, knowledge of the importance of fatigue for these patients and of the factors associated with their fatigue is limited. The aim of the current investigation was to gain more insight into fatigue as related to radiotherapy by answering the following questions. First, how is the experience of fatigue best described? Secondly, to what extent is fatigue related to sociodemographic, medical (including treatment), physical and psychological factors? Finally, is it possible to predict which patients will suffer from fatigue after completion of radiotherapy? Patients with different types of cancer receiving radiotherapy with curative intent (n = 250) were interviewed before and within 2 weeks of completion of radiotherapy. During treatment, patients rated their fatigue at 2-weekly intervals. Results indicate a gradual increase in fatigue over the period of radiotherapy and a decrease after completion of treatment. Fatigue scores obtained after radiotherapy were only slightly, although significantly, higher than pretreatment scores. After treatment, 46% of the patients reported fatigue among the three symptoms that caused them most distress. Significant associations were found between post-treatment fatigue and diagnosis, physical distress, functional disability, quality of sleep, psychological distress and depression. No association was found between fatigue and treatment or personality characteristics. Multivariate regression analysis demonstrated that the intensity of pretreatment fatigue was the best predictor of fatigue after treatment. In view of this finding, a regression analysis was performed to gain more insight into the variables predicting pretreatment fatigue. The degree of functional disability and impaired quality of sleep were found to explain 38% of the variance in fatigue before starting radiotherapy. Fatigue in disease-free patients 9 months after treatment is described in paper (B) in this issue.     

Fatigue in women with myocardial infarction

This study measured fatigue in women 6 weeks after myocardial infarction. Fatigue was experienced by the women as chronic, generalized, intermittent, and longstanding. More than one third of the women attributed their fatigue directly to the heart attack or hospitalization. Significant relations were found between fatigue and the physiological dimension of the Sickness Impact Sale (SIP), the Perceived Health Assessment and Risk Protection Survey (PHARPS), and the site of infarction, as well as with the psychological dimension of the SIP. There was an inverse significant relation between fatigue scores and the Psychological General Well-Being (PGWB) Index. Although not reaching statistical significance, fatigue scores for women 65 and older were higher than for younger women.     

Type of mastectomy and quality of life for long term breast carcinoma survivors

BACKGROUND: Despite numerous studies of partial mastectomy and psychologic morbidity in the first 24 months following surgery, little is known about the long term psychosocial repercussions of partial and total mastectomy. METHODS: The effect of the type of mastectomy on psychologic adjustment was assessed among 124 breast carcinoma survivors, 47 of whom underwent partial mastectomy and 77 of whom underwent total mastectomy, 8 years after initial treatment. Interviews were also conducted 3 and 18 months after surgery. Psychologic distress was assessed using the Psychiatric Symptom Index. Other outcomes included physical symptoms, patients' perceptions of their own health, satisfaction with the type of surgery performed and with the appearance of the scar, and marital and sexual adjustments. RESULTS: No statistically significant differences between partial and total mastectomy were observed with respect to long term quality of life. Age at diagnosis modified the relation between the type of mastectomy and psychologic distress in both the short term and the long term (P = 0.04). Among women younger than 50 years, partial mastectomy appeared to be protective against distress when compared with total mastectomy. In contrast, among women age 50 years or older, partial mastectomy was associated with higher psychologic distress levels at all interviews. CONCLUSIONS: Assessed globally, partial and total mastectomy appear to be equivalent treatments in terms of patients' long term quality of life. However, both short term and long term distress levels after partial and total mastectomy may depend on patients' age at diagnosis. The findings of this study suggest that the increased use of partial mastectomy may lessen the negative effects of breast carcinoma on younger survivors' quality of life. Nevertheless, total mastectomy may be an appropriate initial treatment for some women who truly choose it.     

The clinical diagnosis of heart failure in older patients

OBJECTIVE: To review the differences in presentation and clinical manifestation of heart failure in older and younger patients and to determine if these differences influence the ability to diagnose the disorder clinically. Based on this information, an approach to diagnosing heart failure in older patients is provided. DATA SOURCE: Scientific reports regarding heart failure in both the general population and the geriatric population were identified from repeated searches of MEDLINE data base and citations from appropriate articles. DATA EXTRACTION AND SYNTHESIS: Relevant data were obtained from articles, with special importance placed on studies designed to examine older patients exclusively or as a subgroup in a larger study. Review of data pertaining to clinical characteristics and presentation of heart failure was performed, with emphasis on comparing the characteristics between age groups. Specific cardiac diseases that cause ventricular impairment in older patients were assessed, and the importance of systolic versus diastolic dysfunction in this age group was analyzed. CONCLUSION: Clinical diagnosis of heart failure in older patients may be difficult because of the absence of typical symptoms and physical findings. When present, the symptoms and signs may be mistakenly diagnosed as caused by concomitant disorders or aging changes. In other older patients, the symptoms and signs will be obscured by the presence of aging changes or the presence of other diseases. As a result of these difficulties, the initial diagnosis of heart failure in older patients is made later in the course of the cardiac disease process; older patients will be more unstable, and secondary preventive therapies may be of less benefit than in younger patients with the disorder. Though clinically difficult, the differentiation between systolic and diastolic ventricular dysfunction is mandatory in all older patients with heart failure.     

Prognosis in men and women coming to the emergency room with chest pain or other symptoms suggestive of acute myocardial infarction

BACKGROUND: Previous studies suggest a gender-related difference in prognosis among patients with ischaemic heart disease. In the present study, we aimed to describe the characteristics and prognosis among patients with suspected ischaemic heart disease in relation to gender. METHODS: During the 21 months of the study, all patients who came to the medical emergency room of one single hospital as a result of chest pain or other symptoms suggestive of acute myocardial infarction were prospectively followed for 1 year. RESULTS: A total of 5362 patients were admitted on 7157 occasions; men accounted for 55% of the admissions. The 1-year mortality rate was 11% for men compared with 10% for women. The women were older and had a higher prevalence of known congestive heart failure and hypertension, whereas the prevalence of previous myocardial infarction was higher in men. When correcting for the dissimilarities in age and history of cardiovascular diseases, male gender appeared as an independent predictor of death. Development of myocardial infarction occurred in 25% of the men and 16% of the women (P < 0.001) during 1 year. The symptoms that brought patients to the emergency room were interpreted as being caused by myocardial infarction or myocardial ischemia in 29% of men compared with 21% of women (P < 0.001). CONCLUSIONS: In a consecutive series of patients with chest pain or other symptoms suggesting acute myocardial infarction in the emergency room, male gender was an independent risk indicator for death during 1 year. This might be explained by a higher occurrence of coronary artery disease in men than in women in this patient population.     

Patients'' views on residual blood use for research purposes

OBJECTIVE: This study assessed the effect of nocturnal hypoglycemia on well-being cerebral function, and physical fatigue the next day in 10 subjects with IDDM. RESEARCH DESIGN AND METHODS: After an exercise test to determine work-loads corresponding to 30 and 60% VO2max, volunteers were studied twice, 4 weeks apart. Blood glucose was lowered one night to 2.3-2.7 mmol/l for 1 h, and at the control visit, hypoglycemia was avoided. The next morning, well-being was assessed using the minor symptom evaluation profile (MSEP), and cerebral function was assessed with the paced auditory serial addition test, the digit symbol substitution test, trail making part B, four-choice reaction time, and auditory P300 latency. Subjects then exercised at predetermined workloads corresponding to 30% VO2max for 30 min and 60% VO2max until exhaustion. Fatigue was assessed every 10 min using the Borg scale for rating of perceived exertion. RESULTS: All three components of the MSEP scored higher (indicating more symptoms) after the hypoglycemic night compared with the control night (P < 0.01 contentment, sleep; P < 0.001 vitality). None of the cerebral function tests performed the next day was affected by hypoglycemia. Exercise capacity was similar at both visits, but subjects were more fatigued after the hypoglycemic night (P < 0.01, analysis of variance). There were no differences in potassium, catecholamine, glucose, or lactate concentrations between visits either before or during exercise. CONCLUSIONS: One hour of hypoglycemia at night affects a subject's sense of well-being, but not cerebral function, the next day. The greater fatigue after the hypoglycemic night cannot be explained by the biochemical parameters measured.     

Metabolism of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in isolated rat lung and liver

PURPOSE: Assessment of sustained voluntary contraction of the external sphincter is helpful in evaluating the patient who has a defecation disorder on presentation. A new index of external sphincter function is described. METHOD: A prospective registry of patients referred for computerized anal manometry using standard protocols was reviewed. Patients were grouped by primary symptoms; those with overlapping complaints were excluded. The rate of fatigue, defined as the change in stationary squeeze over a 40-second period of voluntary contraction, was calculated by linear regression analysis. Fatigue rate index, a calculated measure of time necessary for the external sphincter to become completely fatigued, was determined to permit comparison of external sphincter fatigue in patients with different complaints. RESULTS: Twenty-six healthy volunteers (15 women; mean age, 45 years), 33 patients with a primary complaint of anal seepage (13 women; mean age, 53 years), 75 patients with gross incontinence (61 women; mean age, 53 years), and 49 patients with severe constipation (41 women; mean age, 45 years) were evaluated. Mean resting and squeeze pressures were 55 mmHg and 107 mmHg for volunteers, 37 mmHg and 97 mmHg for patients with seepage, 30 mmHg and 49 mmHg for incontinent patients, and 56 mmHg and 93 mmHg for constipated patients. Pudendal neuropathy, as evidenced by a prolonged pudendal nerve terminal motor latency (> 2.4 ms), was identified in 13 percent of volunteers, 32 percent of patients with seepage, 54 percent of incontinent patients, and 38 percent of constipated patients. Mean fatigue rate index was 3.3 minutes for volunteers, 2.3 minutes for seepage patients, 1.5 minutes for incontinent patients, and 2.8 minutes for constipated patients. Compared with volunteers and patients with seepage, the incontinent patients had a significantly shorter fatigue rate index (P < 0.05; Student's t-test), which was independent of the variations in resting pressure (P < 0.05; two-way analysis of variance). CONCLUSION: The external anal sphincter is normally subject to fatigue. Patients with worsening degrees of incontinence have a predictably lower fatigue rate index. Fatigue rate index is a simple measure of external sphincter integrity, which may be used in assessment of sphincter function and future treatment protocols.     

Fatigue following traumatic brain injury: Frequency, characteristics, and associated factors.

Objectives: To document the frequency, characteristics, and factors associated with fatigue following traumatic brain injury (TBI). Design: Survey methodology and multivariate statistical design. Setting: Rehabilitation center and community. Participants: 452 participants aged 16 years and over with minor to severe TBI who answered a questionnaire measuring diverse aspects of fatigue as well as different dimensions of psychological distress, pain, and sleep quality. Measures: Proportion of participants reporting being significantly fatigued. Validated measures of fatigue, sleep quality, and psychological distress. Results of a logistic regression analysis. Results: Significant fatigue was reported by 68.5% of participants. Mental fatigue was the most prominent type of fatigue, followed by physical fatigue. Fatigue was present even several years following the accident and had many perceived impacts on day-to-day function. Factors associated with fatigue were a shorter time since injury; being on long-term disability leave; and higher levels of sleep problems, cognitive disturbances, and anxiety. Conclusion: Fatigue is a prevalent problem after TBI that requires more clinical and scientific attention because it probably has important repercussions on the quality of rehabilitation.

Functional status and depression among men and women with congestive heart failure

OBJECTIVE: The study was designed 1) to examine the prevalence of depression in patients with congestive heart failure (CHF); 2) to explore associations between the physician's rating of functional status (NYHA class) and patient's assessment of functional status (physical limitation, dyspnea) with symptoms of depression; and 3) to explore gender related differences in relation to physician's rating and patient's rating of function status, and symptoms of depression. METHOD: A sample of 119 clinically stable heart failure patients (85 males and 34 females) was recruited from an outpatient cardiology hospital practice. The patients underwent a physical examination and completed a set of questionnaires. Prevalence of depressive symptoms and the association of these symptoms with NYHA class and patient's perceived functional status was studied. RESULTS: Findings indicate that depressive symptoms were not predominant among this sample of CHF patients. Path analyses showed non-significant direct associations between NYHA class as well as patient's perception of dyspnea with depression. In contract, the subjective indicator of physical limitations was strongly associated with symptoms of depression among the males, but this relation was not significant among the females. CONCLUSIONS: Results suggest that men and women respond differently to the burden of heart failure. However, interpretation of the results from the present study should be considered as tentative and additional research is required to examine mechanisms that explain gender differences in response to heart failure.     

The influence of desmopressin on blood loss during spinal fusion surgery in neuromuscular patients

PURPOSE: Fatigue and impairment of physical performance are common and severe problems of cancer patients. We describe the effect of an aerobic exercise program designed for cancer patients suffering from these symptoms. METHODS: Five cancer patients (4 female, 1 male, age 18 to 55), participated in the training program. Fatigue had been present for a time ranging between 5 wk and 18 months and hindered the patients from carrying out normal daily activities. The training program consisted of walking daily on a treadmill with an intensity corresponding to a lactate concentration of 3 +/- 0.5 mmol.L-1 and was carried out for 6 wk. RESULTS: By the end of the exercise program we observed an improvement in maximal physical performance (from 6.4 +/- 0.4 km.h-1 to 7.5 +/- 0.9 km.h-1, P < 0.05) and maximal walked distance (from 1640 +/- 724 m to 3300 +/- 953 m, P < 0.05). Heart rate and lactate concentration by an equivalent submaximal workload (5 km.h-1) were significant reduced (from 138 +/- 21 beats.min-1 to 113 +/- 20 beats.min-1, P < 0.05, and from 2.6 +/- 1.4 mmol.L-1 to 1.3 +/- 0.6 mmol.L-1, P < 0.05); all patients experienced a clear reduction of fatigue and could carry out normal daily activities again without substantial limitations. CONCLUSION: We conclude that an aerobic exercise program of precisely defined intensity, duration, and frequency can be prescribed as therapy for primary fatigue in cancer patients.     

Trends of morbidity and mortality in chronic heart failure in Catalonia

INTRODUCTION: The epidemiology of chronic heart failure, specifically its morbidity and mortality, is insufficiently known, despite the fact that it has an important economic impact because of the pharmacological treatment and the high hospitalization rate. OBJECTIVE: To analyze the trends of mortality and morbidity of chronic heart failure in Catalonia during the periods 1975-1994 and 1989-1994 respectively. PATIENTS AND METHODS: Specific mortality and morbidity rates (ages 45-65, and older than 65) were calculated for both sexes. Standardised mortality rates were also calculated for mortality rates using the European population as the reference. RESULTS: The trend of mortality of chronic heart failure in the population of 45-65 is stable, the rates being higher for men than for women. The trend in the age group older than 65 shows an important increase from 1983 on, higher in women than in men. Morbidity (hospitalization discharge rates) increases slightly in the population of 45-65 years, especially in men; in the population older than 65 an important increase is observed for both sexes. CONCLUSIONS: Trend of mortality is increasing specifically in women older than 65, while trends of morbidity are clearly increasing for both age groups.     

Intra-urban variations in incidence and mortality in myocardial infarction. A study from the myocardial infarction register in the city of Malm?, Sweden

AIM: To assess to what extent intra-urban variations and time trends of mortality in ischaemic heart disease are related to incidence of disease. METHODS AND RESULTS: Incidence and mortality data were retrieved from the myocardial infarction register in Malm?. Age- and sex-adjusted incidence varied between the 17 city areas from 469 to 681/10(5) (P=0.003), and mortality from 286 to 446/10(5) (P=0.017). Socio-demographic risk factors for ischaemic heart disease were more prevalent in high rate areas. About 70% of the variance in mortality was explained by the variance in incidence. From 1986 to 1992, incidence declined by 3.6%/year in men (P=0.004) and by 0.9%/year in women (P=0.31). Mortality decreased by 4.1%/year in men (P=0.01) and by 1.9%/year in women (P=0.15). Incidence and mortality changes were statistically significant only in men>65. In younger age groups, incidence and mortality decreased in men but increased in women. CONCLUSIONS: In this urban population, there were large intra-city differences in mortality from ischaemic heart disease. During the period 1986 1992 there was a parallel decline in mortality and incidence. There were, however, substantial variations both in terms of residence and subject.     

A population-based twin study of self-esteem and gender

BACKGROUND: Self-esteem (SE), a widely used construct in the social sciences, is usually conceptualized as a reflection of socialization and interpersonal experiences that may differ considerably between the genders. METHODS: The Rosenberg self-esteem scale was assessed at personal interview in both members of 3793 unselected twin pairs (1517 male-male, 856 female-female and 1420 male-female) from the population-based Virginia Twin Registry. Gender effects on SE were assessed by both analysis of variance and biometrical twin modelling. RESULTS: The mean SE score was slightly but significantly lower in women v. men, and in women who grew up with a male v. a female co-twin. Twin modelling suggested that: (i) individual differences in self-esteem in both men and women were best explained by genetic and individual-specific environment factors; (ii) heritability estimates were similar in women (32%) and in men (29%); and (iii) the same genetic factors that influenced SE in women also influenced SE in men. Analyses supported the validity of the equal environment assumption for SE. The heritability of SE cannot be explained by the moderate correlation between SE and symptoms of depression. CONCLUSIONS: These results are inconsistent with prominent gender-related aetiological models for SE, which postulate that individual differences arise from socialization experiences both within and outside the home of origin which differ widely for the two genders. Instead, a significant proportion of the population variance in SE is due to genetically-influenced temperamental variables that are the same in men and women.     

Older women's beliefs about physical activity

Physical activity may contribute to important health and well-being outcomes among older adults. Efforts to understand determinants of physical activity are necessary to plan effective interventions. The theory of planned behavior has been successfully applied to a variety of health behaviors. Previous research using the theory of planned behavior has not addressed beliefs about overall physical activity among community-dwelling older women. Qualitative interviews were conducted with 30 older women to identify behavioral beliefs, perceived control beliefs, and normative beliefs, which influence physical activity decisions. Content analyses of responses revealed three major themes: social influences on physical activity, psychosocial benefits of activity, and joint problems and fatigue as factors that interfere with activity. These findings about physical activity were compared with published findings about episodic exercise among 30 similar women who took part in an episodic exercise study. The result was the discovery that the women in this study talked about physical activity as embedded in their social lives while the women in the episodic exercise study viewed exercise as separate from their daily lives. These findings of beliefs about overall physical activity suggest a social model may be useful in planning public health interventions to increase activity among older women.     

Decision making by general practitioners in diagnosis and management of lower urinary tract symptoms in women

OBJECTIVE: To identify factors influencing decision making by general practitioners in the diagnosis and treatment of lower urinary tract symptoms in women. SETTING: Two suburban London general practices. SUBJECTS: Women presenting to their family doctor with lower urinary tract symptoms. DESIGN: After each consultation the doctor completed a questionnaire on presenting symptoms; clinical examination; investigations undertaken; presence of psychological, social, and menstrual problems; patients' requests for antibiotics; antibiotic prescribing; knowledge of the patient; attitude towards the consultation; and any other factors assisting in diagnosis and management. Finally, doctors predicted the presence or absence of clinically important bacteriuria. Each woman completed a demographic questionnaire, the 12 item general health questionnaire, and the modified menstrual distress questionnaire, after which each provided a clean catch midstream urine sample. Case notes were examined for information on previous reports of results of urine analysis. RESULTS: When the general practitioners did not know the patients well they were 4.5 times more likely to assume that there was a clinically important infection. When they knew the patient well, they were four times more likely to make a correct prediction of the test result and 12 times less likely to prescribe antibiotics. Doctors were five times more likely to predict the test result correctly in patients from social classes 1 and 2 and were six times more likely to prescribe antibiotics for the older women in the sample. CONCLUSIONS: In women presenting with urinary tract symptoms, these family practitioners seemed to take no particular regard of physical, psychological, or menstrual factors in making their assessments. They were most accurate in their prediction of the result of urine analysis and least likely to prescribe antibiotics when they had a good general knowledge of the patient. Which came first, the diagnosis or prescribing, is difficult to say and probably differed in individual cases. Doctors tended to be more conservative in their management of older women and those whom they knew less well.     

The existence of a fatigue syndrome after glandular fever

This prospective cohort study was designed to test whether a distinct fatigue syndrome existed after the onset of glandular fever. Two hundred and fifty primary care patients, with either glandular fever or an ordinary upper respiratory tract infection (URTI) were interviewed three times in the 6 months after the clinical onset of their infection. At each interview a standardized psychiatric interview was given and physical symptoms were assessed. There were 108 subjects with and Epstein-Barr virus (EBV) infection; 83 subjects had glandular fever not caused by EBV and 54 subjects had an ordinary URTI. Five subjects were excluded because they had no evidence of an infection. Principal components analyses of symptoms supported the existence of a fatigue syndrome, particularly in the two glandular fever groups. The addition of symptoms not elicited by the standard interviews gave the full syndrome. This included physical and mental fatigue, excessive sleep, psychomotor retardation, poor concentration, anhedonia, irritability, social withdrawal, emotional lability, and transient sore throat and neck gland swelling with pain. A fatigue syndrome probably exists after glandular fever.     

Depression and risk of coronary heart disease in elderly men and women: New Haven EPESE, 1982-1991. Established Populations for the Epidemiologic Studies of the Elderly

BACKGROUND: Results of several recent studies suggest that depression is predictive of incident coronary disease. However, few studies have examined this relationship in the elderly, the age at which most coronary heart disease (CHD) becomes clinically manifest. METHODS AND RESULTS: Data are from the New Haven, Conn, cohort (N = 2812) of the Established Populations for the Epidemiologic Studies of the Elderly project. Baseline information on depressive symptoms and CHD risk factors was collected during an in-person interview in 1982. Nonfatal myocardial infarctions were identified through monitoring of admissions to local hospitals and were validated by medical chart review. Cause of death was obtained from death certificates for all deceased participants. Outcomes were defined as CHD deaths (n = 255) and total incident CHD events (n = 391) between January 1, 1982, and December 31, 1991. There was no association between depressive symptoms and CHD outcomes in men. Among women, depressive symptoms were associated with an age-adjusted relative risk of 1.03 (per unit increase on the symptom scale) for CHD mortality (P=.001) and total CHD incidence (P=.002). These associations were largely unaffected by adjustment for established CHD risk factors but were reduced to nonsignificant levels after additional adjustment for impaired physical function. Additional analysis showed a significant association for depressive symptoms among women who had no physical function impairments or who survived at least 3 years without an event. CONCLUSION: Depressive symptoms may not be independent risk factors for CHD outcomes in elderly populations in general but may increase risk among relatively healthy older women.     

Spectroscopic and thermodynamic evidence for a complex denaturation mechanism of bovine beta-lactoglobulin A

PURPOSE/OBJECTIVES: To investigate the patterns of functioning and psychosocial adjustment of midlife and older women following surgery for breast cancer. Differences between those who received follow-up adjuvant therapy and those who did not also were compared. DESIGN: 2 x 3 mixed design with one between-groups factor (type of treatment) and one within-subjects factor (time). SETTING: Four midwestern hospitals. SAMPLE: 46 patients with breast cancer who are age 55 or older. METHODS: Baseline data about presurgical functional status and other variables were obtained during the first week after surgery. Follow-up data were obtained at six weeks, three months, and six months postsurgery. Data were collected via telephone interviews and mailed questionnaires. MAIN RESEARCH VARIABLES: Functional status, patient symptomatology, quality of life (QOL), demands of illness, and type of treatment (surgery only versus surgery plus adjuvant therapy). FINDINGS: No differences existed between the two treatment groups at baseline, with the exception of lower functional status reported by the surgery-only group. In the surgery-only group, functional status improved significantly from six weeks to three months postsurgery. The most frequently reported symptoms of both groups included fatigue and pain. CONCLUSIONS: These results suggest that both groups did equally well, regardless of whether they received adjuvant therapy (radiation or chemotherapy). Neither QOL nor demands of illness differed between the two groups, nor did these scores change significantly over time following surgery. IMPLICATIONS FOR NURSING PRACTICE: These findings suggest that women undergoing surgery for breast cancer, whether they receive adjuvant therapy or not, may have functional and psychosocial needs that could be effectively addressed by nursing interventions pre- and postsurgery.
