Metabolic syndrome in an Hispanic population–cardiovascular complications

The metabolic syndrome (MetS) is presently one of the main medical problems in developing countries. This syndrome was studied in Puerto Rico at the Cardiovascular Center of Puerto Rico and the Caribbean with emphasis on understanding the cardiovascular complications. The medical records of patients admitted between 1999 to 2005 were evaluated for three or more MetS diagnostic criteria. One hundred and seventy-three patients met the consensus criteria of metabolic syndrome (MetS). The mean age of those diagnosed with MetS was 60 years of age. Fifty-seven percent were males and 42 percent females. The mean body mass was 30 kg/m. The ejection fraction was found to be subnormal (49±8%) and the end systolic dimension of the left atrium was increased ( 45±10 mm ) in comparison to a group of diabetic patients without MetS used for comparison. The incidence of atrial fibrillation was found to be 16% higher in the MetS group than in the comparison group. The number of cases of metabolic syndrome recorded within the Hispanic population of Puerto Rico showed a higher incidence of atrial fibrillation without ventricular tachycardia. This is thought to be as a result of the abnormal left ventricular and atrial function

Renal cell carcinoma with nodal metastases in the absence of distant metastatic disease: prognostic indicators of disease-specific survival.

Item does not contain fulltextOBJECTIVES: Outcome of patients with exclusive renal cell carcinoma (RCC) nodal metastases without distant metastases is not extensively described. We explored the ability of standard risk factors such as tumour size, Fuhrman grade, histologic subtype and symptom classification to predict renal cell carcinoma-specific survival (RCC-SS). METHODS: Analyses targeted 171 patients with RCC nodal metastases and absence of distant metastases. Univariable, multivariable, and predictive accuracy analyses addressed RCC-SS with the intent of identifying independent and most informative predictors of RCC-SS in this cohort of patients. RESULTS: Median RCC-SS was 2.3 yr. Symptom classification (61.3%, p<0.001) demonstrated the highest univariable accuracy. In multivariable analyses, symptom classification contributed the most to the combined predictive accuracy of all variables (+4.2%, p<0.001), followed by Fuhrman grade (+2.3%) and histologic subtype (+1.0%). CONCLUSIONS: Renal cell carcinoma-specific survival of patients with exclusive nodal metastases may show important variability. In presence of systemic symptoms, survival is extremely poor. Substantially better survival may be expected in patients with local or no symptoms. This observation has important implications when adjuvant therapies are considered
