AIM:To investigate associations between ethnicity,age and sex and the risk,colon distribution and density scores of diverticular disease(DD).METHODS:Barium enemas were examined in 1000 patients:410 male,590 female;760 whites,62 Asians,44 black africans(BAs),and 134 other blacks(OBs).Risks and diverticula density of left-sided DD(LSDD) and rightsided-component DD(RSCDD = right-sided DD + right and left DD + Pan-DD) were compared using logistic ***:Four hundred and forty-seven patients had DD(322 LSDD and 125 RSCDD).Adjusted risks:(1) LSDD:each year increase in age increased the odds by 6%(95% CI:5-8,SE:0.8%,P < 0.001);Asians:odds ratio(OR):0.23(95% CI:0.10-0.53,SE:0.1,P ≤ 0.001) and OBs:OR:0.25(95% CI:0.14-0.43,SE:0.07,P ≤ 0.001) appeared protected vs Whites;(2) RSCDD:each year increase in age increased the odds by 4%(95% CI:2-6,SE:1%,P < 0.001);females were 0.60 times(95% CI:0.40-0.90,SE:0.12,P = 0.01) less likely than males to have RSCDD;BAs were 3.51 times(95% CI:1.70-7.24,SE:1.30,P < 0.001) more likely than Whites to have RSCDD;and(3) DD density scores:each year increase in age increased the odds of highdensity scores by 4%(95% CI:1-6,SE:1%,P < 0.001);RSCDD was 2.77 times(95% CI:1.39-3.32,SE:0.67,P < 0.001) more likely to be of high density than *** further signif icant differences were found in the adjusted ***:Right colonic DD might be more common and has higher diverticula density in the west than previously *** appear predisposed to DD,whereas other ethnic differences appear conserved following migration.

Precipitating factors leading to decompensation of chronic heart failure in the elderly patient in South-American community hospital

引用

Journal of Geriatric Cardiology 2011年第1期8卷 12-14页

作者： Alejandro Diaz Cleto Ciocchini Mariano Esperatti Alberto Becerra Sabrina Mainardi Alejandro farah Department of Cardiology Hospital Privado de Comunidad Cordoba 4545 Mar del Plata 7600 Argentina Department of Internal Medicine Hospital Privado de Comunidad Cordoba 4545 Mar del Plata 7600 Argentina

Background Exacerbations of heart failure appear frequently associated with precipitating factors not directly related to the evolution of cardiac disease. There still a paucity of data on the proportional distribution of precipitating factors specifically in elderly patients. The aim of this study was to examine prospectively the precipitating factors leading to hospitalization in elderly patients with heart failure in our community hospital. Methods We evaluate elderly patients who need admissions for decompensate heart failure. All patients were reviewed daily by the study investigators at the first 24 h and closely followed-up. Decompensation was defined as the worsening in clinical NYHA class associated with the need for an increase in medical treatment （at minimum intravenously diuretics）. Results We included 102 patients （mean age 79 ± 12 years）. Precipitating factors were identified in 88.5%. The decompensation was sudden in 35% of the cases. Noncompliance with diet was identified in 52% of the patients, lack of adherence to the prescribed medications amounted to 30%. Others precipitating factors were infections （29%）, arrhythmias （25%）, acute coronary ischemia （22%）, and uncontrolled hypertension （15%）, miscellaneous causes were detected in 18% of the cases （progression of renal disease 60%, anemia 30% and iatrogenic factors 10%）. Concomitant cause was not recognizable in 11.5%. Conclusions Large proportion heart failure hospitalizations are associated with preventable precipitating factors. Knowledge of potential precipitating factors may help to optimize treatment and provide guidance for patients with heart failure. The presence of potential precipitating factors should be routinely evaluated in patients presenting chronic heart failure.

Diabetic ketoacidosis remains one of the most serious complications of diabetes mellitus. Among its precipitating factors is myocardial ischemia, responsible for 1% of the cases of diabetic *** Diabetic ketoacidosis both with and without hyperkalemia has been reported to mimic a myocardial infarction pattem on ECG with ST segment elevation, described as pseudoinfarction pattern. Thus, it is important to raise awareness among physicians, as subjecting patients to invasive medical management can be avoided. We present a case of a 47-year-old female with diabetic ketoacidosis and hyperkalemia with initial ECG findings of ST segment elevation, but an urgent left heart catheterization revealed non-obstructive coronary disease.
