(1/7350) Geographic, demographic, and socioeconomic variations in the investigation and management of coronary heart disease in Scotland.

OBJECTIVE: To determine whether age, sex, level of deprivation, and area of residence affect the likelihood of investigation and treatment of patients with coronary heart disease. DESIGN, PATIENTS, AND INTERVENTIONS: Routine discharge data were used to identify patients admitted with acute myocardial infarction (AMI) between 1991 and 1993 inclusive. Record linkage provided the proportion undergoing angiography, percutaneous transluminal coronary angioplasty (PTCA), and coronary artery bypass grafting (CABG) over the following two years. Multiple logistic regression analysis was used to determine whether age, sex, deprivation, and area of residence were independently associated with progression to investigation and revascularisation. SETTING: Mainland Scotland 1991 to 1995 inclusive. MAIN OUTCOME MEASURES: Two year incidence of angiography, PTCA, and CABG. Results-36 838 patients were admitted with AMI. 4831 (13%) underwent angiography, 587 (2%) PTCA, and 1825 (5%) CABG. Women were significantly less likely to undergo angiography (p < 0.001) and CABG (p < 0.001) but more likely to undergo PTCA (p < 0.05). Older patients were less likely to undergo all three procedures (p < 0.001). Socioeconomic deprivation was associated with a reduced likelihood of both angiography and CABG (p < 0.001). There were significant geographic variations in all three modalities (p < 0.001). CONCLUSION: Variations in investigation and management were demonstrated by age, sex, geography, and socioeconomic deprivation. These are unlikely to be accounted for by differences in need; differences in clinical practice are, therefore, likely.  (+info)

(2/7350) Early death during chemotherapy in patients with small-cell lung cancer: derivation of a prognostic index for toxic death and progression.

Based on an increased frequency of early death (death within the first treatment cycle) in our two latest randomized trials of combination chemotherapy in small-cell lung cancer (SCLC), we wanted to identify patients at risk of early non-toxic death (ENTD) and early toxic death (ETD). Data were stored in a database and logistic regression analyses were performed to identify predictive factors for early death. During the first cycle, 118 out of 937 patients (12.6%) died. In 38 patients (4%), the cause of death was sepsis. Significant risk factors were age, performance status (PS), lactate dehydrogenase (LDH) and treatment with epipodophyllotoxins and platinum in the first cycle (EP). Risk factors for ENTD were age, PS and LDH. Extensive stage had a hazard ratio of 1.9 (P = 0.07). Risk factors for ETD were EP, PS and LDH, whereas age and stage were not. For EP, the hazard ratio was as high as 6.7 (P = 0.0001). We introduced a simple prognostic algorithm including performance status, LDH and age. Using a prognostic algorithm to exclude poor-risk patients from trials, we could minimize early death, improve long-term survival and increase the survival differences between different regimens. We suggest that other groups evaluate our algorithm and exclude poor prognosis patients from trials of dose intensification.  (+info)

(3/7350) Peritoneal cytology in the surgical evaluation of gastric carcinoma.

Many patients undergoing surgery for gastric carcinoma will develop peritoneal metastases. A method to identify those patients at risk of peritoneal recurrence would help in the selection of patients for adjuvant therapy. Peritoneal cytology has received little attention in the West, but may prove a useful additional means of evaluating patients with gastric cancer. The aims of this study were to evaluate sampling techniques for peritoneal cytology in patients with gastric cancer, to assess the prognostic significance of free peritoneal malignant cells and to discover the effect of the operative procedure on dissemination of malignant cells. The study is based on 85 consecutive patients undergoing surgical treatment of gastric cancer and followed up for 2 years or until death. Peritoneal cytology samples were collected at laparoscopy, and at operation prior to resection by intraperitoneal lavage and serosal brushings. After resection, samples were taken by peritoneal lavage, imprint cytology of the resected specimen and post-operatively by peritoneal irrigation via a percutaneous catheter. Malignant cells were diagnosed by two independent microscopists. Preoperative peritoneal lavage yielded malignant cells in 16 out of 85 cases (19%). The yield of free malignant cells was increased by using serosal brushings (by four cases) and imprint cytology (by two cases); all of the cases had evidence of serosal penetration. One serosa-negative case exhibited positive cytology in the post-resection peritoneal specimen in which the preresection cytology specimen was negative. Survival was worse in the cytology-positive group (chi2 = 25.1; P< 0.0001). Among serosa-positive patients, survival was significantly reduced if cytology was positive, if cases yielded by brushings and imprint cytology were included (log-rank test = 8.44; 1 df, P = 0.004). In conclusion, free peritoneal malignant cells can be identified in patients with gastric cancer who have a poor prognosis; the yield can be increased with brushings and imprint cytology in addition to conventional peritoneal lavage. Evaluation of peritoneal cytology by these methods may have a role in the selection of patients with the poorest prognosis who may benefit most from adjuvant therapy.  (+info)

(4/7350) Profound variation in dihydropyrimidine dehydrogenase activity in human blood cells: major implications for the detection of partly deficient patients.

Dihydropyrimidine dehydrogenase (DPD) is responsible for the breakdown of the widely used antineoplastic agent 5-fluorouracil (5FU), thereby limiting the efficacy of the therapy. To identify patients suffering from a complete or partial DPD deficiency, the activity of DPD is usually determined in peripheral blood mononuclear cells (PBM cells). In this study, we demonstrated that the highest activity of DPD was found in monocytes followed by that of lymphocytes, granulocytes and platelets, whereas no significant activity of DPD could be detected in erythrocytes. The activity of DPD in PBM cells proved to be intermediate compared with the DPD activity observed in monocytes and lymphocytes. The mean percentage of monocytes in the PBM cells obtained from cancer patients proved to be significantly higher than that observed in PBM cells obtained from healthy volunteers. Moreover, a profound positive correlation was observed between the DPD activity of PBM cells and the percentage of monocytes, thus introducing a large inter- and intrapatient variability in the activity of DPD and hindering the detection of patients with a partial DPD deficiency.  (+info)

(5/7350) The effect of race and sex on physicians' recommendations for cardiac catheterization.

BACKGROUND: Epidemiologic studies have reported differences in the use of cardiovascular procedures according to the race and sex of the patient. Whether the differences stem from differences in the recommendations of physicians remains uncertain. METHODS: We developed a computerized survey instrument to assess physicians' recommendations for managing chest pain. Actors portrayed patients with particular characteristics in scripted interviews about their symptoms. A total of 720 physicians at two national meetings of organizations of primary care physicians participated in the survey. Each physician viewed a recorded interview and was given other data about a hypothetical patient. He or she then made recommendations about that patient's care. We used multivariate logistic-regression analysis to assess the effects of the race and sex of the patients on treatment recommendations, while controlling for the physicians' assessment of the probability of coronary artery disease as well as for the age of the patient, the level of coronary risk, the type of chest pain, and the results of an exercise stress test. RESULTS: The physicians' mean (+/-SD) estimates of the probability of coronary artery disease were lower for women (probability, 64.1+/-19.3 percent, vs. 69.2+/-18.2 percent for men; P<0.001), younger patients (63.8+/-19.5 percent for patients who were 55 years old, vs. 69.5+/-17.9 percent for patients who were 70 years old; P<0.001), and patients with nonanginal pain (58.3+/-19.0 percent, vs. 64.4+/-18.3 percent for patients with possible angina and 77.1+/-14.0 percent for those with definite angina; P=0.001). Logistic-regression analysis indicated that women (odds ratio, 0.60; 95 percent confidence interval, 0.4 to 0.9; P=0.02) and blacks (odds ratio, 0.60; 95 percent confidence interval, 0.4 to 0.9; P=0.02) were less likely to be referred for cardiac catheterization than men and whites, respectively. Analysis of race-sex interactions showed that black women were significantly less likely to be referred for catheterization than white men (odds ratio, 0.4; 95 percent confidence interval, 0.2 to 0.7; P=0.004). CONCLUSIONS: Our findings suggest that the race and sex of a patient independently influence how physicians manage chest pain.  (+info)

(6/7350) Studies on structural changes of the carotid arteries and the heart in asymptomatic renal transplant recipients.

BACKGROUND: The present study was designed to characterize early structural changes of large arteries in renal transplant recipients with no clinical evidence of cardiovascular disease and normal blood pressure values, and to analyse the relationship between arterial alterations and those of the heart. METHODS: Intima media thickness and atherosclerotic plaques of the carotid arteries as well as left ventricular geometry and function were examined in 35 asymtomatic renal transplant recipients and 29 age- and sex-matched healthy controls by high resolution B-mode ultrasound and by echocardiography. RESULTS: Intima-media thickness of the carotid arteries was significantly higher in renal transplant recipients (1.21+/-0.08 mm) than in healthy controls (0.74+/-0.04 mm) (P<0.001). Atherosclerotic plaques were found in the majority of renal transplant recipients (71% vs 14% in healthy controls, P<0.001). Left ventricular mass index was significantly increased in the group of renal transplant recipients (264+/-13 g, 146+/-7 g/m2) when compared with healthy controls (155+/-8 g, 83+/-4 g/m2) (P<0.001). Multiple regression analysis in renal transplant recipients showed that intima media thickness of the carotid arteries was significantly related to left ventricular mass index (P<0.02), but not to age, blood pressure, body mass index, serum creatinine, cholesterol and lipoprotein (a) levels. In the group of healthy controls, intima-media thickness of the carotid artery was related to age (P<0.002), but not to left ventricular mass index or the other independent variables. CONCLUSIONS: The present study documents pronounced intima-media thickening in asymptomatic renal transplant recipients. Atherosclerotic lesions are present in most renal transplant recipients with no clinical evidence of cardiovascular disease. We observed a parallelism between arterial wall thickening and left ventricular hypertrophy, although blood pressure levels were normal during haemodialysis therapy and after renal transplantation.  (+info)

(7/7350) Ruptured abdominal aortic aneurysms: selecting patients for surgery.

OBJECTIVES: Mortality from ruptured abdominal aortic aneurysm (RAAA) remains high. Despite this, withholding surgery on poor-prognosis patients with RAAA may create a difficult dilemma for the surgeon. Hardman et al. identified five independent, preoperative risk factors associated with mortality and proposed a model for preoperative patient selection. The aim of this study was to test the validity of the same model in an independent series of RAAA patients. METHODS: A consecutive series of patients undergoing surgery for RAAA was analysed retrospectively by case-note review. Thirty-day operative mortality and the presence of the five risk factors: age (> 76 years), creatinine (Cr) (> 190 mumol/l), haemoglobin (Hb) (< 9 g/dl), loss of consciousness and electrocardiographic (ECG) evidence of ischaemia were recorded for each patient. RESULTS: Complete data sets existed for 69 patients (mean age: 73 years, range: 38-86 years, male to female ratio: 6:1). Operative mortality was 43%. The cumulative effect of 0, 1 and 2 risk factors on mortality was 18%, 28% and 48%, respectively. All patients with three or more risk factors died (eight patients). CONCLUSIONS: These results lend support to the validity of the model. The potential to avoid surgery in patients with little or no chance of survival would spare unnecessary suffering, reduce operative mortality and enhance use of scarce resources.  (+info)

(8/7350) Repair of ruptured thoracoabdominal aortic aneurysm is worthwhile in selected cases.

INTRODUCTION: The risks and benefits of operating on patients with ruptured thoracoabdominal aortic aneurysm (TAAA) have not been defined. The aim of the present study is to report this unit's experience with operations performed for ruptured TAAA over a 10-year period. METHODS: Interrogation of a prospectively gathered computerised database. PATIENTS: Between 1 January 1983 and 30 June 1996, 188 consecutive patients with TAAA were operated on, of whom 23 (12%) were operated for rupture. RESULTS: There were nine survivors (40%). Patients whose preoperative systolic blood pressure remained above 100 mmHg were significantly more likely to survive (4/8 vs. 13/15, p = 0.03 by Fisher's exact test). Survival was also related to Crawford type: type I (two of three survived); II (none of six); III (two of six); and IV (five of eight). All non-type II, non-shocked patients survived operation. Survivors spent a median of 28 (range 10-66) postoperative days in hospital, of which a median of 6 (range 2-24) days were spent in the intensive care unit. Survivor morbidity comprised prolonged ventilation (> 5 days) (n = 3); tracheostomy (n = 1); and temporary haemofiltration (n = 2). No survivor developed paraplegia or required permanent dialysis. CONCLUSIONS: Patients in shock with a Crawford type II aneurysm have such a poor prognosis that intervention has to be questioned except in the most favourable of circumstances. However, patients with types I, III and IV who are not shocked on presentation can be salvaged and, where possible, should be transferred to a unit where appropriate expertise and facilities are available.  (+info)
