We investigated the problem of outcome prediction from seven risk factors in 40 severely head injured patients-13 favorable and 27 unfavorable outcomes. By applying stepwise logistic discriminant analysis to the patients' data, we selected three significant risk variables: cerebrospinal fluid (CSF) CK-BB isoenzyme activity recorded on admission, severely raised intracranial pressure (more than 40 mmHg) and age, respectively. CSF CK-BB activity, which quantifies the initial neurological damage, proved to be the best prognostic factor. The presence of severe intracranial hypertension was always associated with a bad outcome, whereas its absence was not necessarily indicative of good prognosis. Finally, we combined the three selected variables into a single risk index, which allowed correct predictions in 92% of patients with favorable outcome and in 85% of patients with unfavorable outcome (total predictive efficiency 88%). 相似文献

目的探讨鼻咽癌患者放化疗前预后营养指数(prognostic nutritional index,PNI)与预后的关系。方法回顾性分析四川省肿瘤医院初诊鼻咽癌患者153例,收集放化疗前患者的血液学指标及临床资料并随访。用Kaplan-Meier法分析放化疗前血液学指标、PNI对鼻咽癌总生存时间的影响,进一步用Cox风险比例回归模型进行多因素分析。结果患者3、5、10年总生存率分别为89.54%、83%、75.16%。单因素及多因素分析结果提示,放化疗前PNI、白细胞计数(WBC)是鼻咽癌患者预后的独立危险因素。PNI低水平组(≤49.45)鼻咽癌患者3、5、10年总生存率低于高水平组(PNI49.45)。结论 PNI和WBC是鼻咽癌的独立预后指标,与鼻咽癌患者的总生存时间相关。 相似文献

目的明确慢性肾衰竭患者开始透析时血清白蛋白浓度(SALB)与肾功能水平(GFR)之间是否存在线性相关。方法通过查阅中南大学湘雅二医院与湖南省人民医院两大血液透析中心1998~2005年间开始第一次透析的所有514例慢性肾衰竭患者的病案获得血清白蛋白和肾功能检查等实验室数据及其他人口统计学数据。将患者按不同标准分组并计算整个患者群及不同分组情况下的血清白蛋白浓度与肾功能水平之间是否存在线性相关关系。结果①整体而言,血清白蛋白浓度和肾功能水平之间并无直线相关;②当GFR<8.5时,GFR与SALB呈正直线相关。而当GFR>8.5ml/min时,两者之间无线性相关;③进一步以不同原发病分组以后,慢性肾小球肾炎组与总体表现出同样的趋势;而糖尿病组和高血压组等其他组由于病例数较少未发现这种线性相关关系;④性别、年龄、体重、透析方式等对这种相关关系是否成立无影响。结论①肾功能水平下降到一定水平以后会引起低白蛋白血症;并且当GFR<8.5ml/min左右,SALB随GFR下降而下降,两者呈线性正相关;②制定科学的开始透析的肾功能标准,在出现严重的营养不良前及时透析对提高患者的生活质量和降低死亡率有重要意义。 相似文献

214 patients among 282 consecutive admissions had at least one measurement of serum albumin (SA) during their stay on the ICU and were classified according to their stay on the ICU and were classified according to their lowest value of SA. Mean SA was 2.88±0.74 g/100 ml. Survivors had a mean SA (3.18±0.60) higher than non-survivors (2.35±0.68 g/100 ml) (p<0.05). 64% of patients were admitted with an abnormally low SA (less than 3.5 g/100 ml) and in 56% of these the initial value was higher than the last. Mortality increased in the groups with lower SA and the level of SA was associated with infection (x2=73.9) and mortality (x2=69.7) (p<0.05). The percentage of infected patients who died increased in groups with lower SA. 相似文献

Purpose: We aimed to assess the prospective association of serum albumin with venous thromboembolism (VTE) risk and evaluate if the association is independent of or modified by inflammation, as measured by high sensitivity C-reactive protein (hsCRP).Design: We analysed data of 2176 men aged 42–61 years free from VTE in the Kuopio Ischemic Heart Disease study, with serum albumin concentrations measured at baseline using Coulter’s bromocresol purple colorimetric assays. Hazard ratios (HRs) (95% confidence intervals [CI]) were calculated for VTE.Results: There were 109 validated cases of VTE recorded during a median follow-up of 24.9 years. The risk of VTE increased linearly below a serum albumin concentration of ~48?g/l. In Cox regression analysis adjusted for established risk factors and other potential confounders, the HR (95% CI) for VTE per 1 standard deviation lower serum albumin was 1.23 (1.02–1.47). The association remained persistent on further adjustment for hsCRP 1.22 (1.01–1.46). Furthermore, the association was not modified by hsCRP and persisted on exclusion of men with elevated hsCRP levels.Conclusions: In middle-aged Caucasian men, low serum albumin is associated with an increased risk of VTE, consistent with a linear dose-response relationship. The association is independent of and not modified by inflammation.

??In a population-based prospective cohort study, low serum albumin was associated with an increased risk of VTE in a linear dose-response manner and this association was independent of and not modified by inflammation.

IntroductionThere is an increasing incidence of Pneumocystis pneumonia (PcP) among individuals without human immunodeficiency virus (HIV) infection (non-HIV PcP). However, prognostic factors for patients with non-HIV PcP have not been identified. Moreover, A-DROP (for classifying the severity of community-acquired pneumonia) or the blood urea nitrogen-to-serum albumin ratio (BUN/Alb), which is reported to be a predictor of mortality of community-acquired pneumonia, has not been established as an efficient prognostic factor in patients with non-HIV PcP. In this study, we analyzed the prognostic factors for non-HIV PcP and evaluated the prognostic ability of A-DROP and the BUN/Alb ratio.MethodsThis retrospective study involved a chart review of the medical records of 102 patients diagnosed with non-HIV PcP between January 2003 and May 2019 at five medical facilities.ResultsOverall, 102 patients were involved in this study. The 30-day mortality rate for non-HIV PcP was 20.5% in this study population. Compared with survivors, non-survivors had significantly lower serum albumin levels and significantly higher age, corticosteroid dosage at the PcP onset, alveolar–arterial oxygen gradient, A-DROP score, lactate dehydrogenase levels, blood urea nitrogen levels, and BUN/Alb ratio. Multivariate analysis showed that a high BUN/Alb ratio at treatment initiation was significantly associated with 30-day mortality risk. The receiver operating characteristic curves showed that A-DROP score had the highest prognostic ability in estimating 30-day mortality.ConclusionsIn patients with non-HIV PcP, a high BUN/Alb ratio is an independent prognostic predictor of mortality risk, and A-DROP is useful for classifying the severity. 相似文献

Background
The transpulmonary thermodilution technique allows the determination of cardiac preload (global end-diastolic volume index) and quantification of pulmonary edema (extravascular lung water index [EVLWI]). Pulmonary edema commonly develops in critically ill patients; however, the underlying pathophysiology, that is, hydrostatic (cardiac) or permeability-induced (noncardiac), often remains unclear. In this study, hemodynamic and serum parameters of osmolarity and oncotic pressure were analyzed to identify risk factors for increased EVLWI.Methods
A retrospective, single-center analysis in an intensive care unit of a university hospital was performed. No interventions were made for the study. Forty-two critically ill patients were included, and 126 simultaneous hemodynamic measurements and serum determinations were analyzed by logistic regression and Spearman rank correlation coefficient analysis.Results
Global end-diastolic volume index (P = .001), serum albumin (P = .006), and serum osmolarity (P = .029) were significant factors for increased EVLWI (defined as >10 mL/kg).Conclusion
Hypervolemia, hypoalbuminemia, and high plasma osmolarity are associated with increased EVLWI. 相似文献20.

PURPOSE: The objective of this study is to study the epidemiology, outcome, and prognostic factors of critically ill patients treated with continuous venovenous hemodiafiltration (CVVHDF). MATERIALS AND METHODS: Observational cohort was done in a French 16-bed intensive care unit (ICU) from a university-affiliated urban hospital. All patients requiring, in the opinion of the treating physician, the initiation of CVVHDF were included in the study. RESULTS: One hundred ninety-seven patients with acute renal failure (ARF) treated with CVVHDF were studied. The incidence of ARF treated with CVVHDF was 5.9% in the ICU with a mortality rate of 71.6%. A multivariate analysis identified 3 independent factors associated with fatal outcome: mechanical ventilation, sepsis, and septic shock requiring vasoactive drug. In contrast, 2 independent factors predicted a favorable outcome: nonoliguric ARF and serum creatinine concentration higher than 34 mg/L at CVVHDF initiation. A flowchart determined by the chi2 Automatic Interaction and Detection statistical method allowed for the identification of patients' subgroups with different mortality rates ranging from 25% to 100%. CONCLUSIONS: In our series, ARF treated with CVVHDF was associated with a high overall ICU mortality rate (71.6%). However, our prognostic flowchart identified patients with low mortality rates for which renal replacement therapy must be initiated with no discussion as soon as required. 相似文献
