BACKGROUND: Blood transfusion has repeatedly been demonstrated to be an independent risk factor for postinjury multiple organ failure (MOF). Previously believed to represent a surrogate for shock, packed red blood cell (PRBC) transfusion has recently been shown to result in neutrophil priming and pulmonary endothelial cell activation. We have previously observed that the generation of inflammatory mediators is related to the length of PRBC unit storage. The purpose of this study was to determine if age of transfused PRBC is a risk factor for the development of postinjury MOF. METHODS: Using our prospective database of trauma patients at risk for developing MOF, we identified patients who developed MOF (MOF+) and received 6 to 20 units of PRBCs in the first 12 hours following injury. A similar cohort of patients, matched for ISS and transfusion requirement, who did not develop MOF (MOF-) were also identified. The age of each unit of PRBC transfused in the first 6 hours was determined. Multiple logistic regression was performed to determine if age of transfused blood is an independent risk factor. RESULTS: Sixty-three patients were identified, 23 of whom were MOF+. There was no difference in ISS and transfusion requirement between MOF+ and MOF- groups. MOF+ patients, however, were significantly older (46+/-4.7 years versus 33+/-2.3 years). Moreover, mean age of transfused blood was greater in the MOF+ patients (30.5+/-1.6 days versus 24+/-0.5 days). Similarly, the mean number of units older than 14 and 21 days old were greater in the MOF+ patients. Multivariate analysis identified mean age of blood, number of units older than 14 days, and number of units older than 21 days as independent risk factors for MOF. CONCLUSION: The age of transfused PRBCs transfused in the first 6 hours is an independent risk factor for postinjury MOF. This suggests that current blood bank processing and storage technique should be reexamined. Moreover, fresh blood may be more appropriate for the initial resuscitation of trauma patients requiring transfusion. 相似文献

Although the high risk for cardiovascular events in patients with end-stage renal disease (ESRD) is well known, recent data provide compelling evidence that even mild to moderate kidney disease is an important and independent risk factor for cardiac events. This increased risk does not seem to be explained by traditional risk factors as defined by the Framingham cohort. The examination of nontraditional risk factors has resulted in the identification of, among others, oxidant stress, hyperhomocystinemia, carbamylation, nitric oxide synthase inhibitors, and abnormal lipoproteins as potential pathways to explain the accelerated atherosclerosis in patients with kidney disease. Well-designed clinical trials should lead to the clarification of the relative importance of these factors in the pathogenesis of atherosclerotic disease. 相似文献

PURPOSE: To better stratify risk and to verify previous prevalence reports, we conducted a retrospective cohort study comparing the lifetime incidence of nephrolithiasis in patients with spondyloarthropathies (SpA) and rheumatoid arthritis (RA). PATIENTS AND METHODS: Patients with SpA or rheumatoid factor-positive RA were identified from the rheumatology clinics of two Veterans Affairs hospitals and the University of Minnesota. Among them, 168 were confirmed to meet the American College of Rheumatology criteria and gave informed consent to participation. They were sent a survey regarding their rheumatologic diagnosis, coexistent conditions, medications, and history of kidney stones. Of the total, 143 patients responded and met the criteria for analysis. Rheumatoid arthritis patients were age and sex matched with SpA patients as controls. RESULTS: Populations were similar in all categories except that RA patients were more likely to have used prednisone (P < 0.001), bisphosphonates (P < 0.001), and calcium supplementation (P = 0.03). Kidney stones were reported by 23 (29.11%) of the 79 SpA patients compared with 8 (12.5%) of the 64 RA patients (chi (2) = 5.75; P = 0.025). Subgroup analysis of self-reporting stone history in 85 patients was found to be reliable on imaging review (sensitivity 82%; specificity 100%). CONCLUSIONS: Self-reporting of kidney stones by patients is a reliable measure. Despite adjusting for medication use and matching two similar arthritic populations, patients with SpA had a higher incidence of kidney stones than those with RA. This finding suggests that SpA is an independent risk factor for nephrolithiasis. Future studies will evaluate urinary risk factors and polymorphisms in the ANKH gene that may predispose to stone formation in this high-risk group. 相似文献

PURPOSE: Patients with spina bifida are at a high risk for having an immediate type allergy to latex products. The number of surgical interventions, atopy and catheterization are well known responsible factors, whereas the condition of spina bifida per se has not been established as an independent risk factor. MATERIALS AND METHODS: A total of 131 patients with a shunted hydrocephalus (48 with spina bifida and 83 of other origin) were investigated for sensitization to latex by skin prick tests and determination of specific IgE. We hypothesized that the diagnosis of spina bifida will increase the risk for latex sensitization while considering potential confounding factors. Thus, we performed a multiple logistic regression analysis to determine independent risk factors. RESULTS: Whereas 56.3% (27/48) of children with spina bifida proved sensitized against latex, this result was the case in only 16.9% (14/83) with another cause of hydrocephalus (p <0.001). The mean number of surgical interventions was 6.2 for patients with no latex sensitization and 9.3 for those with sensitization (p = 0.02). Of patient sensitized to latex 43.9% had a history of atopy compared to 15.5% of those not sensitized (p = 0.02). Sensitized and nonsensitized patients were comparable regarding gender and catheterization. In a multiple logistic regression analysis the cause of the hydrocephalus (odds ratio 6.76 for spina bifida), atopy (odds ratio 3.37) and the number of surgical interventions (odds ratio 1.14 per operation) were identified as independent risk factors. CONCLUSIONS: The increased risk of latex sensitization in patients with spina bifida seems to be disease associated. Possible explanations for this finding may be genetic, antigen mediated, early latex exposure and immunological reasons. 相似文献

PURPOSE: The potential effects of age at onset of smoking on cardiovascular diseases have been studied little, in contrast to the well-established evidence supporting a causal role of cigarette smoking in these diseases. We sought to analyze the relationship between age at smoking onset and development of symptomatic peripheral arterial occlusive disease (PAOD). METHODS: A population-based sample of 573 active or former male smokers aged 55 to 74 years were studied. Present or previous symptomatic PAOD was confirmed by noninvasive testing. RESULTS: Sixty-one subjects (10.6%) had symptomatic PAOD. Prevalence of disease increased with earlier starting age (15.6% if 16 years) of smoking. After controlling for risk factors that meet confounding factor criteria (ie, subject age and number of pack-years), men who started smoking at age 16 or earlier had a substantially higher risk for development of PAOD (odds ratio, 2.19; 95% CI, 1.15-4.15; P =.016) than men who began to smoke at a later age. CONCLUSIONS: A starting age for smoking of 16 years or earlier more than doubles the risk of future symptomatic PAOD regardless of the amount of exposure to cigarette smoking. 相似文献

An elevated factor VIII level has been shown to be an independent risk factor for venous thrombosis. However, physicians screen for this factor far less frequently than they screen for other coagulopathies. The causes of increased factor VIII levels are likely a combination of genetic and acquired variables. The authors describe a case of a healthy 48-year-old woman found to have a cerebral venous thrombosis, with her only identifiable risk factor being an elevated factor VIII level. 相似文献

OBJECTIVE: Several studies have shown a relation between hyperhomocysteinaemia and vascular disease. To assess the risk of deep-vein thrombosis (DVT) associated with hyperhomocysteinaemia, we studied plasma homocysteine levels in patients with deep-vein thrombosis and in normal control subjects. MATERIALS AND METHODS: We measured plasma homocysteine levels in 48 patients with deep-vein thrombosis and in 33 healthy controls matched to the patients according to age and sex. Plasma homocysteine levels were measured with high performance liquid chromatography and fluorescence detection. Hyperhomocysteinaemia was defined as a plasma homocysteine level about 15 micromol/L in both groups. The diagnosis of all patients with deep-vein thrombosis (n=48) was verified by Doppler ultrasonography. RESULTS: Plasma homocysteine levels were found to be increased in the deep-vein thrombosis group compared the control group (p<0.001, t-test). The mean plasma homocysteine level in the patients was 17.1 SD 5.13 micromol/L (range 6.4-31.3), and that in the controls was 9.0 SD 1.27 micromol/L (range 6.0-11.5). The association between elevated homocysteine levels and venous thrombosis was stronger among men than among women. CONCLUSIONS: The increased plasma homocysteine levels we have observed may have a causative role in the development of deep-vein thrombosis. 相似文献

Hyperfibrinogenemia is an independent risk factor for atherosclerotic renal artery stenosis 总被引:2,自引:0,他引:2

It is important to identify patients at risk for atherosclerotic renal artery stenosis because renal artery stenosis is a progressive disease and a potentially correctable problem. To determine the risk factors for atherosclerotic renal artery stenosis, we performed renal arteriography at the time of cardiac catheterization in 270 patients (M:F, 193:77, mean age: 59 years) with clinical ischemic heart disease. Before the procedure, demographic data, medical history, physical findings and laboratory data were obtained. The degree of coronary artery stenosis and renal artery stenosis was quantified with automatic edge detection technique. Significant renal artery stenosis, defined as a narrowing of the diameter by more than 50%, was identified in 28 (10%) patients. Three patients (1%) had bilateral disease. Significant coronary artery disease, defined as a narrowing of the diameter by more than 50%, was present in 231 patients (85%). By univariate logistic regression analysis, older age (68 +/- 8 vs. 58 +/- 10 years), the presence of hypertension (61% vs. 38%), the extent of coronary artery disease, a high fibrinogen level (391 +/- 93 mg/dl vs. 335 +/- 109 mg/dl), a low albumin level (3.9 +/- 0.4 g/dl vs. 4.1 +/- 0.4 g/dl), and a low hemoglobin level (12.5 +/- 1.6 g/dl vs. 13.5 +/- 1.6 g/dl) were associated with the presence of renal artery stenosis (p < 0.05). Serum lipids, lipoprotein(a), creatinine, sex, smoking, or diabetes were not associated. By multivariate logistic regression analysis, older age (OR: 2.43 analyzed by 10 years increment, p = 0.0001), the presence of hypertension (OR: 2.68, p = 0.039) and a higher fibrinogen level (OR: 1.63 analyzed by 100 mg/dl increment, p = 0. 038) were significant risk factors of renal artery stenosis. Fibrinogen level was negatively correlated with albumin level (r = -0.18, p = 0.004). These results suggest that hyperfibrinogenemia as well as old age and hypertension are independent risk factors for atherosclerotic renal artery stenosis. Copyright Copyright 1999 S.

BackgroundCorticosteroid use continues to rise nationally. Studies have evaluated the impact of chronic steroid use on surgical outcomes in smaller populations. This study investigated the impact of chronic steroid use on perioperative surgical outcomes in a surgical cohort of more than 5 million surgical patients, using a statistically rigorous methodology.MethodsThe National Surgical Quality Improvement Program Database was queried 2008–2016 to evaluate chronic steroid use. Patient demographics, comorbidities, and outcomes were compared, using χ2 and t test analysis, and then repeated after propensity score matching. Finally, a double-adjustment logistic regression was utilized, yielding odds ratios to assess the effect of chronic steroids on perioperative outcomes within the matched population.ResultsBetween 2008 and 2016, a total of 5,244,588 patients met inclusion criteria, of whom 181,901 (3.5%) were taking steroids for a minimum of 30 days before surgery. Patients on chronic steroids had significantly more comorbidities compared with the remaining population. After propensity score matching and double-adjusted logistic regression, chronic steroid use was found to be associated with increased surgical complications and poorer surgical outcomes. Chronic steroid use significantly increased a patient’s risk of having a hospital stay longer than 30 days by 19%, risk of readmission within 30 days by 58%, risk of reoperation by 21%, and risk of death by 32%.ConclusionAfter controlling for differences in comorbidities and demographics, patients on chronic steroids have significantly poorer perioperative outcomes. Chronic steroid use should be evaluated and, if possible, addressed before surgery, given their significant impact on surgical outcomes. 相似文献

HYPOTHESIS: Preexisting morbidities are risk factors for perioperative arterial or venous thromboembolic events and subsequent death within 30 postoperative days. DESIGN: Prospective cohort study. SETTING: University-affiliated general hospital. PATIENTS: A total of 21,903 surgery patients treated from January 1, 1991, through December 31, 2002. MAIN OUTCOME MEASURES: Independent risk factors for perioperative arterial or venous thromboembolic events. RESULTS: History of atrial fibrillation and coronary artery disease increased the risk of myocardial infarction (odds ratio [95% confidence interval], 4.3 [2.8-6.7]). History of stroke increased the risk of stroke (2.4 [1.4-4.1]) and death (4.7 [1.3-17.3]). Diabetes mellitus increased the risk of myocardial infarction (2.1 [1.3-3.2]), and hyperuricemia increased the risk of stroke (3.5 [1.2-9.8]), and both increased the risk of death (4.3 [1.3-14.1] and 11.8 [2.2-63.5], respectively). History of myocardial infarction increased the risk of deep vein thrombosis (7.7 [1.7-34.7]). Cancer increased the risk of all thromboembolism (2.4 [1.9-3.2]). Trend analysis showed that preexisting morbidities will increase 1.5-fold and thromboembolic events will increase 3-fold during the next decade. CONCLUSION: Cardiac and cerebrovascular diseases, metabolic diseases, and cancer are becoming increasingly high-risk comorbidities for perioperative acute thromboembolism syndrome. 相似文献

BACKGROUND: Acute renal failure (ARF) after cardiac operation with cardiopulmonary bypass is associated with a high mortality rate. The purpose of this study was to determine and quantify whether valvular heart operation is an independent risk factor for developing ARF. METHODS: We retrospectively analyzed 5,132 consecutive patients who underwent cardiac operation involving cardiopulmonary bypass between April 1997 and March 2001. Patients with significant renal impairment (preoperative serum creatinine > 200 micromol/L) were excluded. A multivariable logistic regression model was constructed to identify independent risk factors for the postoperative development of ARF. RESULTS: In 151 (2.9%) patients ARF developed before hospital discharge. The crude incidence of ARF for isolated coronary artery bypass grafting, isolated valve(s) operation, and valve(s) with coronary artery bypass grafting operation was 1.9%, 4.4%, and 7.5%, respectively (p < 0.001). The results of the logistic regression analysis found that valve operation with or without coronary artery bypass grafting was an independent risk factor for the development of postoperative ARF (odds ratio 2.68, 95% confidence interval 1.89 to 3.79; p < 0.001). Other independent predictors of ARF were increased preoperative serum creatinine levels, urgent or emergent operation, insulin-dependent diabetes, and increased cardiopulmonary bypass time. CONCLUSIONS: Valve operation is an independent risk factor for postoperative ARF. This risk is further increased by prolonged cardiopulmonary bypass. 相似文献

Nosocomial pneumonia (NP) is associated with a significant mortality, 66% in a previous retrospective study of NP complicating intra-abdominal sepsis (IAS). We prospectively compared the outcome of NP complicating IAS with that of recurrent IAS (R-IAS) in the absence of NP. Data were collected prospectively on 300 patients with IAS; 34 patients who presented with pneumonia were excluded from the analysis (44% mortality). One hundred seventy-one patients with no NP and no R-IAS (group 1) had a hospital mortality of 20% (34 patients); 36 without NP in whom R-IAS developed (group 2) had a 17% mortality (six patients); and 47 with NP but no R-IAS (group 3) had a 53% mortality (25 patients). Finally, 12 patients who had both NP and R-IAS suffered a 75% mortality (nine patients). We examined the relationships among the following putative risk factors and mortality: APACHE (acute physiology and chronic health evaluation) II score (at initial presentation with IAS), the need for mechanical ventilatory assistance following initial treatment for peritonitis, steroid requirement, generalized peritonitis vs abscess, and the need for surgical as opposed to percutaneous treatment. Using mortality as the dependent variable, group 2 vs 3 as the explanatory variable, and the risk factors as confounders, logistic regression analysis indicated that the group difference was significant after controlling for confounders. We conclude that NP complicating IAS is an independent risk factor associated with a significant mortality compared with R-IAS. These data challenge the notion that death in IAS is usually due to recurrent or persistent intra-abdominal infection. 相似文献

Introduction
Erectile dysfunction (ED) and cardiovascular disease (CVD) share a great number of common risk factors. There is growing evidence that aldosterone, an independent CVD risk factor, is associated with ED.Aims
The purpose of this study was to determine the relationship between plasma aldosterone and erectile dysfunction.Methods
This study recruited 287 participants, ranging from 18 to 84 years old; 217 were suffering from ED, diagnosed by the International Index of Erectile Function 5 (IIEF-5) scores. Based on IIEF-5 scores, patients were divided into one control group and three ED groups (mild ED; moderate ED; severe ED).Main outcome measures
The differences in principal characteristics, blood routine, sexual hormone, adrenal hormone, thyroid hormone, renal function, liver function and blood lipid were compared between ED and control groups.Results
Our study demonstrated that the difference of mean plasma aldosterone levels between ED group and the control group was statistically significant (P < 0.05). Stepwise logistic regression analysis of all the possible factors support the role of aldosterone as an independent risk factor for ED (OR 1.011; 95 % CI 1.003–1.018; P = 0.004). Similar statistical methods were applied to the comparison between moderate to severe ED group and control to mild ED group (OR 1.017; 95 % CI 1.009–1.024; P < 0.001). ROC curve and the area under the curve (0.718; 95 % CI 0.643–0.794; P < 0.001) were performed to assess the diagnostic effect and to compare the severity of risk with the known independent risk factors, such as age and cholesterol (0.704; 95 % CI 0.631–0.778; P < 0.001). When using a 374 pg/mL cut-off value from Youden index, the OR of ED group versus controls is 3.106 (95 % CI 1.458–6.617), while the OR of moderate to severe ED versus control and mild ED is 5.480 (95 % CI 3.108–9.662).Conclusions
We determined that elevated plasma aldosterone concentration is an independent risk factor for ED. Our findings also indicate that the aldosterone, a well-recognized contributor to vascular injury, might be a potential bond between ED and CVD.18.
OBJECTIVE: To assess whether starting to smoke in childhood increases the risk of obstructive airways disease (OAD) in adult life. METHODS: A retrospective cohort analysis was undertaken of 12 504 current and ex-smokers in the EPIC-Norfolk cohort. The main exposure was starting to smoke during childhood (age <16 years). Three definitions of OAD were used: doctor diagnosed asthma, doctor diagnosed bronchitis/emphysema, and "any OAD" (doctor diagnosed asthma or bronchitis/emphysema, or taking medication used in the treatment of OAD). RESULTS: Childhood smokers had significantly more pack years of exposure and poorer lung function than subjects who started to smoke in adulthood (>/=16 years). Compared with starting in adulthood, starting to smoke in childhood was associated with a greater risk of bronchitis/emphysema in female smokers (OR 1.79, 95% CI 1.25 to 2.56) and ex-smokers of both sexes (OR 1.29, 95% CI 1.07 to 1.55 in men and OR 1.40, 95% CI 1.05 to 1.85 in women), and of "any OAD" in female smokers (OR 1.72, 95% CI 1.24 to 2.38) and male and female ex-smokers (OR 1.20, 95% CI 1.03 to 1.40 in men and 1.34, 95% CI 1.07 to 1.57 in women). After adjustment for pack years, childhood smoking was associated with poorer lung function (FEV(1) 92.3% predicted in adult smokers and 89.5% in childhood smokers, p = 0.03) and a greater risk of bronchitis/emphysema (adjusted OR 1.55, 95% CI 1.08 to 2.24) and for "any OAD" (OR 1.54, 95% CI 1.10 to 2.13) in female smokers but not in male and female ex-smokers. CONCLUSION: Starting to smoke in childhood is associated with an increased risk of airways disease because of the extra pack years smoked. In women, childhood smoking is itself an independent risk factor for the development of airways disease. 相似文献

BACKGROUND: Twelve percent of Americans are diagnosed and treated for mental illness annually. The relationship between mental illness and intentional injuries such as assault and suicide has previously been described. However, unintentional injury among mentally ill adults has not been characterized. The purpose of this study was to identify relationships between mental illness diagnosis and unintentional injury. We hypothesized that diagnosed mental illness is an independent risk factor for unintentional injury and it increases the risk of recidivism. METHODS: In this retrospective cohort study, trauma registry data, medical records, and outpatient mental health care data from the San Francisco Department of Public Health Billing Information System (BIS) were used to identify patients admitted with unintentional injury at a Level I urban trauma center in 2003 and 2004. Data collected included mechanism of injury, patient outcome and disposition, mental health diagnoses, substance abuse history, presence of homelessness, number of repeat injury events, and outpatient mental health treatment history. The incidence of unintentional injury requiring admission to a trauma center and the risk of intentional injury recidivism in subjects with a mental illness diagnosis were compared with those in subjects without a mental illness diagnosis. The risk of recidivism in those who had received publicly funded outpatient treatment before their injury was also evaluated. RESULTS: Of the 1,709 patients admitted for unintentional injury, 20% had a diagnosis of mental illness. Individuals with mental illness had twice the rate of unintentional injury requiring admission (2.2-2.4 people in 1,000 vs. 1.0-1.1 in 1,000) and 4.5 times the odds of injury recidivism (odds ratio [OR] = 4.5, 95% confidence interval [CI] 3.3-6.1) as those who did not have a mental illness diagnosis. Mental illness was a more robust predictor of injury recidivism than substance abuse (OR = 3.2, 95% CI 2.3-4.3) or homelessness (OR = 2.3, 95% CI 1.5-3.4). Compared with the nonmentally ill group, subjects with mental illness had a longer hospital stay and were less likely to be discharged home. Also, their injuries were more likely the result of falling or being hit by cars, and less likely the result of motor vehicle collisions than subjects without mental illness. CONCLUSIONS: Mental illness is an independent risk factor for unintentional injury and injury recidivism. Individuals with mental illness also have a different pattern of injury and hospitalization. They tended to suffer from different mechanisms of injury, stayed in the hospital longer, and were more likely to be discharged to a skilled nursing facility. Recognition of mental illness as a risk factor for injury may prompt re-examination of resource allocation for mental health and injury prevention and highlights the mentally ill as a prime target population for unintentional injury prevention efforts. 相似文献
