OBJECTIVES: To predict the costs and effects on life expectancy of an AAA screening programme. METHODS: A Markov model was designed to compare the effects of a single screening for a cohort of men 60-65 years with the current no screening strategy. The following health states were distinguished: no AAA, unknown small AAA, follow-up small AAA, unknown large AAA, repaired AAA, rejected large AAA and death. Transition rates between the health states were simulated using cycle times of one year. Transition probabilities were derived from literature and a previous feasibility study. Incremental costs per life year saved were calculated. Sensitivity analyses and discounting for future effects were performed. RESULTS: The expected individual AAA costs for non-screening and AAA screening were euro; 196 and euro; 530 respectively. A difference of 3.5 months life expectancy was found in favour of screening leading to euro; 1176/life-year gained. Costs increased as compliance fell. With a discount rate of 4% the costs are euro; 2021/life-year gained. CONCLUSIONS: One-time ultrasonographic screening for AAA in men aged 60-65 years appears to be cost-effective. 相似文献

Objectives. Type 2 diabetes mellitus has been linked to a decreased risk for abdominal aortic aneurysm (aortic diameter ≥30?mm, AAA) development in men. The aim of this study was to evaluate if such an effect is detectable already around the time of diabetes diagnosis. Design. We cross-sectionally compared aortic diameter at ultrasound screening for AAA in 691 men aged 65 years with incipient or newly diagnosed type 2 diabetes (group A) with 18,262 65-year old control men without diabetes (group B). Results. Aortic diameter did not differ between groups (18.8[17.4–20.8] vs. 19.0[17.5–28.7] mm; p?=?0.43). AAA prevalence was 2.5% in group A and 1.5% in group B (p?=?.010). In logistic regression taking group differences in body mass index (BMI), smoking, presence of atherosclerotic disease and hypertension into account, the difference in AAA prevalence was no longer significant (p?=?.15). Among men in group A, C-peptide (r?=?.093; p?=?.034), but not HbA1c (r?=?.060; p?=?.24) correlated with aortic diameter. Conclusion. Among 65 year old men aortic diameter and AAA prevalence do not differ between those with newly diagnosed type 2 diabetes and those without diabetes. Putative protective effects of type 2 diabetes mellitus against aortic dilatation and AAA development therefore probably occur later after diagnosis of diabetes. 相似文献

Objectives Impaired glucose metabolism and diabetes mellitus has been linked to a decreased risk for abdominal aortic aneurysm development in men. We evaluated potential relationships between blood glucose levels in 1722 men with mean age 34 years and their aortic diameter measured by ultrasound at age 65 years. Design Prospective cohort study. Results Mean follow-up between baseline glucose investigation and aortic ultrasound was 32.8?±?1.8 years. There was no correlation between baseline blood glucose and later aortic diameter (r?=?0.035, p?=?0.146), whereas a weak correlation between body mass index (BMI) and aortic diameter was observed (r?=?0.097 p?<?0.001). In a partial correlation between aortic diameter and glucose levels adjusted for BMI, the correlation did not change (r?=?0.011, p?=?0.66). Neither were there any significant differences in mean aortic diameter between men belonging to different quartiles of baseline blood glucose levels (19.5, 19.1, 19.6 and 19.7?mm, p?=?0.18). Conclusion Fasting blood glucose in 33-year-old men was not associated with their aortic diameter at age 65 years. Potential pathophysiological processes linking disturbed glucose metabolism to a decreased risk for development of abdominal aortic aneurysm in men are therefore probably not relevant until later in life. 相似文献

The objectives of this study were to evaluate quality of life (QOL) and identify its associated factors in climacteric women with a history of breast cancer. A cross-sectional study was performed including 75 breast cancer survivors age 45-65 years who had undergone complete oncologic treatment and nonusers of hormone therapy or tamoxifen in the last 6 months. Sociodemographic and clinical characteristics in addition to the prevalence of climacteric symptoms were evaluated. QOL was evaluated by the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) questionnaire, including eight components that can be condensed into two summaries: a physical component summary (physical functioning, role-physical, body pain, general health) and a mental component summary (vitality, social functioning, role-emotional, and mental health). Generalized linear models were used to analyze the data, allowing the identification of factors affecting QOL, adjusting for confounding variables. The mean age of the participants was 53.1+/-5.9 years. Breast cancer survivors reported good QOL. The most prevalent symptoms were nervousness (69%) and hot flashes (56%). Factors associated with poorer QOL were dizziness, postmenopausal status, and breast-conserving therapy (physical component), as well as insomnia and being married (mental component). In conclusion, participants demonstrated good QOL. We identified factors that may influence QOL in women with breast cancer, highlighting being married, climacteric symptoms, postmenopausal status, and breast-conserving therapy. Given the impact of these factors, health professionals and patients must discuss choices for alleviating climacteric symptoms and explanations for the potential repercussions of breast cancer treatment. 相似文献

Prospective review examined 69 patients aged over 65 years (mean: 73 years; range: 65 to 85 years) who underwent 72 primary hydroxyapatite-coated total hip replacements by one surgeon. The femoral component used was titanium alloy coated by hydroxyapatite on the proximal third and the acetabular component was spherical and unthreaded, coated with hydroxyapatite. All patients were evaluated clinically by Harris Hip Score and radiologically using Engh's criteria with a mean follow-up of 86 months (range: 29 months to 10 years). Preoperative radiologic evaluation for osteoporotic bone using the Singh index was performed. Average Harris Hip Score increased from 45 before surgery to 89 at last follow-up. Two femoral and one-acetabular components were shown to probably be loose, but none was definitely loose or unstable by Engh's criteria. There was no correlation between clinical and radiologic results with respect to age, sex, and preoperative diagnosis. In contrast, significant statistical correlation was demonstrated between Charnley groups A or B, and group C, with regard to the Harris Hip Score (p = 0.047). There was no correlation between Charnley groups and radiological results. There was no statistical difference between patients with osteoporotic bone (Singh 1-3) and non-osteoporotic bone (Singh 4-6) with respect to clinical and radiologic evaluation. These early clinical and radiologic results compare favorably with those of hydroxyapatite-coated total hip replacements for younger patients and cemented total hip replacements in older patients. We recommended that hydroxyapatite-coated total hip replacements should not be reserved for younger patients. They can be used safely in patients over 65 years of age, promising minimal postoperative thigh pain and satisfactory clinical and radiologic results. 相似文献

Eighteen healthy people over 65 years of age were studied to compare the 99mTC-diethylenetriamine pentaacetic acid (DTPA) clearance, the measured 24-hour creatinine clearance and the assessed creatinine clearance using the Cockcroft and Gault (C-G) formula to measure their glomerular filtration rate. Significant correlations were found between the isotopic method and the measured creatinine clearance (r = 0.71; p less than 0.001); the measured creatinine clearance and the C-G formula (r = 0.81; p less than 0.001), and the isotopic method and the C-G formula (r = 0.70; p less than 0.001). The C-G formula correlated better with both the 99mTc-DTPA clearance and the measured creatinine clearance when the female correction factor was used. This study has shown that in healthy, elderly people, the C-G formula for assessing the creatinine clearance correlated extremely well with the standard clinical tests for measuring the glomerular filtration rate. Whilst the formula has clinical value and allows rapid and accurate assessment of renal function in the elderly, the clinician must be aware that the formula relatively underestimates the true renal clearance. 相似文献

BACKGROUND: It has been suggested that snoring alone, without conventional sleep apnoea or hypopnoea, may disrupt sleep and produce substantial daytime hypersomnolence. This study addresses this potential relationship. METHOD: Eight hundred and fifty men, aged 35-65 years, drawn from one general practice were visited at home and asked a range of questions potentially related to sleepiness, snoring, and sleep apnoea; these included inquiries about alcohol and cigarette consumption, nasal stuffiness, shift work, hypnotic or other drug use, and medical diagnoses. In addition, measurements of height, weight, and overnight arterial oxygen saturation were made. The relation between snoring and sleepiness, with allowance made for potentially confounding variables, including sleep apnoea, was assessed by multiple logistic regression. RESULTS: Positive answers to all questions about sleepiness were correlated significantly with self reported snoring. After potentially confounding variables and any sleep apnoea had been controlled for, positive answers to four questions about inappropriate drowsiness or sleepiness were independently related to snoring. For example, the odds ratio of admitting to "having almost had two or more car accidents while driving due to sleepiness" was 5.8 (95% confidence intervals: 2.7-12.5) in an "often" snorer. CONCLUSIONS: Although epidemiological associations such as this do not prove a causal relation, the study suggests that snoring (without classical sleep apnoea) may sometimes reduce sleep quality sufficiently to produce substantial daytime drowsiness. 相似文献

The proportion of the population of the U.S. 65 years of age and over is increasing. Biliary tract disease is estimated to involve 15% of the adult population. A review of 12,200 patients treated surgically at one medical center reveals that 2401 (20%) had acute cholecystitis. There were 93 deaths, for a mortality rate of 3.8%. Sixty-five of the 93 deaths, for a mortality rate of 3.8%. Sixty-five of the 93 deaths occurred in 665 patients 65 years of age and older, for a mortality rate of 9.8%. These elderly patients accounted for 69.9% of the deaths from acute cholecystitis. It is suggested that acute cholecystitis in patients 65 years of age and older may be prevented by a more aggressive surgical approach to cholelithiasis when those patients are younger. Indeed, the present improved methods of diagnosis and an awareness of gallstones by the public is resulting in many more patients seeking medical advice in the early years of the disease. On the basis of a review of an experience in the surgical treatment of acute cholecystitis two proposals are made concerning the management of patients 65 years of age and over. First, the operation should be performed with minimal delay following diagnosis, and such specific correction of physiologic impairment should be performed as is feasible. Second, the procedure to be performed on the elderly patient should be one that alleviates the present problem, and accomplished by imposing the minimal burden upon the patient. 相似文献

OBJECTIVE: To determine major thromboembolic and hemorrhagic complications and predictive risk factors associated with aortic valve replacement (AVR), using bileaflet mechanical prostheses (CarboMedics and St. Jude Medical). DESIGN: A case series. SETTING: Cardiac surgical services at the teaching institutions of the University of British Columbia. PATIENTS AND METHODS: Patients 2 age groups who had undergone AVR between 1989 and 1994 were studied. Group 1 comprised 384 patients younger than 65 years. Group 2 comprised 215 patients 65 years of age and older. RESULTS: The linearized rates of major thromboembolism (TE) occurring after AVR were 1.54%/patient-year for group 1 and 3.32%/patient-year for group 2; the rates for major TE occurring more than 30 days after AVR were 1.13%/patient-year for group 1 and 1.55%/patient-year for group 2. The crude rates for major TE occurring within 30 days of AVR were 1.04% for group 1 and 3.72% for group 2. The death rate from major TE in group 1 was 0.31%/patient-year and in group 2 was 0.88%/patient-year. Of the major TE events occurring within 30 days, 100% of patients in both age groups were inadequately anticoagulated at the time of the event, and for events occurring more than 30 days after AVR, 45% in group 1 and 57% in group 2 were inadequately anticoagulated (INR less than 2.0). The overall linearized rates of major hemorrhage were 1.54%/patient-year for group 1 and 2.21%/patient-year for group 2. There were no cases of prosthesis thrombosis in either group. The mean (and standard error) overall freedom from major TE for group 1 patients at 5 years was 95.6% (1.4%) and with exclusion of early events was 96.7% (1.3%); for group 2 patients the rates were 90.0% (3.2%) and 93.7% (3.0%), respectively. The mean (and SE) overall freedom from major and fatal TE and hemorrhage for group 1 patients was 90.1% (2.3%) and with exclusion of early events was 91.2% (2.3%); for group 2 patients the rates were 87.9% (3.1%) and 92.5% (2.9%), respectively. The 5-year rate for freedom from valve-related death for group 1 patients was 96.3% (2.1%) and for group 2 patients was 97.2% (1.2%). CONCLUSION: The thromboembolic and hemorrhagic complications after AVR with bileaflet mechanical prostheses occur more frequently and result in more deaths in patients 65 years of age and older than in patients years younger than 65 years. 相似文献

ObjectivesTo compare comorbidity measures and to analyze survival rates in men undergoing radical prostatectomy at age 70 years or older.Materials and methodsA total of 329 consecutive patients aged 70 or more years who underwent radical prostatectomy between 1992 and 2004 were studied. The patients were stratified by 5 comorbidity classifications, tumor stage, Gleason score, and PSA value. Mortality was subdivided into overall, comorbid, competing, prostate cancer-specific, and second cancer-specific mortality. Competing risk and Kaplan-Meier survival curves as well as Mantel-Haenszel hazard ratios were calculated. Comparisons were made with the log-rank test. Cox proportional hazard models were used to determine the independent significance of prognostic variables.ResultsConsidering the dose-response relationship, P values and the discrimination of 2 risk groups, the Charlson score was the best of the tested comorbidity classifications in men selected for radical prostatectomy at age 70 years or older. Beside the tumor-related factors Gleason score 8–10 (hazard ratio 2.61, P = 0.0234) and lymph node involvement (hazard ratio 2.89, P = 0.0145), a Charlson score of 1 or greater was identified as an independent predictor of overall mortality (hazard ratio 2.16, P = 0.0441). Without comorbidity or adverse tumor-related risk factors, elderly men had an excellent 10-year overall survival probability (77% to 100%, depending on the classification used), whereas 10-year overall survival was distinctly poor in the presence of lymph node metastases (30%) or Gleason score 8–10 disease (33%).ConclusionsThe Charlson comorbidity score may be used to stratify men selected for radical prostatectomy at age 70 years or older and to estimate long-term survival probability. In the absence of adverse tumor-related parameters or serious comorbidity, long-term survival probability is excellent in this subgroup. 相似文献

Background
Although rupture of intracranial aneurysms carries high mortality and morbidity rates, the clinical and financial benefit of screening certain high-risk groups is uncertain. We designed a mathematical model to interrogate the clinical benefit and cost-effectiveness of screening. 相似文献20.

BACKGROUND: One of the difficulties confronting genetic studies of prostate cancer is the complex and heterogeneous etiology. Given the high population frequency of lesions meeting the histological definition of prostate cancer, a significant portion of men with a positive family history may be diagnosed due to increased surveillance and associated higher likelihood of biopsy. Over diagnosis decreases power to detect genes that increase susceptibility to a clinically significant prostate cancer. METHODS: We re-evaluated all 623 men with prostate cancer in our 188 hereditary prostate cancer families and identified a subset of 244 men with more aggressive disease based upon meeting at least one of the following clinical and/or pathologic criteria: tumor grade Gleason score > or = 7, tumor stage T2c or higher, pretreatment PSA > or = 20 ng/ml, rising PSA after treatment, evidence of metastasis, or death from prostate cancer. RESULTS: Genome-wide screens were re-performed by defining men as affected only if they met the criteria for clinically significant disease. The new analyses identified stronger evidence for linkage in Xq27-28 and 22q, as well as several novel loci, including 3p and 9p. CONCLUSIONS: Although, these results need to be confirmed in independent studies, our approach represents an important step to overcome the impact of over diagnosis in genetic studies of prostate cancer. Larger studies that incorporate this approach are needed. 相似文献
