The bidirectional relation between body mass index (BMI) and heart failure (HF) is complex and not fully understood. The obesity paradox phenomena is controversial and related to patient selection, parameters used for defining abnormal weight, characteristics of HF. Our study sustain the importance of controlling risk factors, in particular plasma glucose, lipid levels, as well as hypertension in patients with HF and BMI over 25 kg/m2. Also, in contrast to the randomized control studies our results can only partially support data related to obesity paradox phenomena.

CONTEXT: Undernutrition is a well known underlying cause in both disease onset and outcome. OBJECTIVE: To associate disease severity with pre surgical nutritional status, the main postsurgical complications, and mortality in esophagus cancer patients. METHOD: Retrospective data from 100 patients (38-81 years old, 85% males) who had undergone esophagectomy (G1/n = 25) or gastro/jejunostomy (G2/n = 75) between 1995 and 2004. Data included clinical, endoscopic, histological (TNM-UICC), dietary, anthropometric, blood chemistry, and postsurgical (>30 days) complications and mortality. Surgical groups were compared by Student's test and existing associations between variables by either c² or Fisher exact tests with P = 0.05. RESULTS: The studied sample was predominantly male (85%), white (80%), smokers and alcoholics (95%), dysphagics (95%) mostly presenting body weight loss before cancer diagnosis (78%). TNM III and IV predominated over I and II, associated (P<0.005) with higher body mass index and hypoalbuminemia (<3.5 mg/dL) frequency. Esophagic obstructions (n = 77) were associated (P = 0.002) with lower body mass index (kg/m²). Postsurgical complications were more common in G1 (69.2%) than G2, predominantly with infections in G2 (80%) and pleura-pulmonary in G1 (61%). Body mass index and lower lymphocyte counts were associated with early infections and postsurgical complications in G2. Plasma albumin levels were lower in this group than G1, and were associated with postsurgical complications and mortality whereas lower lymphocyte counts was associated with mortality in G1. CONCLUSIONS: Disease severity (or late diagnosis) is associated with poor nutritional status and palliative surgery which lead to more complicated postsurgery outcome and mortality. Early diagnosis and nutritional intervention are the recommended actions.

Background: Present rise in the incidence of obesity has led to several opposing reports regarding the association between obesity and stroke outcomes. The objective of this study was to investigate a proposed paradoxical relationship between body mass index (BMI) and functional status in ischemic stroke patients at time of hospital discharge. Methods: Saint Francis Hospital Comprehensive Stroke Center patient databases were utilized in identifying 948 patients eligible for retrospective chart review over a period of 15 months. Subjects were divided into 4 groups according to BMI: underweight (BMI < 18.5 kg/m 2 ), normal weight (BMI 18.5-24.9 kg/m 2 ), overweight (BMI 25.0-29.9 kg/m 2 ), and obese (BMI ≥ 30.0 kg/m 2 ). Covariates, such as age, gender, prior to event modified Rankin scale (mRS), stroke recurrence, and smoking, were considered. Functional status and disability of stroke patients was scored via mRS at hospital discharge. Ordered logistic regression, Pearson’s chi-squared test, and Pearson’s r correlation were used for analysis to assess the association of BMI and functional status in ischemic strokes. Results: Of 948 eligible subjects, 49.9% were female and mean (SD) age was 69.4 (14.5) years. According to BMI, 22 (2.3%) were underweight, 247 (26.1%) normal weight, 319 (33.7%) overweight, and 360 (37.9%) obese. After adjusting for covariates, ischemic stroke patients with an increased BMI (OR, 0.98; 95% CI, 0.96-0.99) were not associated with increased disability risk upon discharge. Obese (16.2%) and overweight (14.1%) patients discharged with a mRS of 0 (back to baseline) or 1 more frequently compared to normal weight (6.1%) and underweight (0.21%) patients ( P <0.001). Furthermore, an inverse association between BMI status and disability was significantly evident ( r = -0.17, P < 0.001). Conclusion: Obese and overweight stroke patients discharge with a lower risk of disability than normal weight and underweight patients, supporting the existence of the “obesity paradox” in stroke. An inverse association between obesity status and functional outcome was identified and remained significant regardless of covariates.
