Reconciling the obesity paradox: Obese patients suffer the highest critical illness associated mortality rates.
The obesity paradox refers to the observation that obese patients admitted to intensive care units (ICU) have lower case fatality as compared to healthy weight patients. However, selection bias could explain the apparent paradox. Our objective was to assess whether obese people have a different overall burden of critical illness associated mortality. ⋯ ICU admission incidence rates were 245.6, 138.2, 178.9, and 421.9 per 100,000 population; 90-day all cause case fatalities were 24.0%, 17.0%, 18.1%, and 16.0%; and critical illness associated mortality rates were 58.8, 23.4, 32.4, and 67.7 per 100,000 population among underweight, healthy weight, overweight, and obese patients, respectively. As compared to patients of healthy weight, those who were underweight (relative risk; RR 2.51; 95% CI, 1.79-3.44), overweight (RR 1.38; 95% CI, 1.16-1.65), and obese (RR 2.89; 2.43-3.43) were each at significantly higher risk for critical illness associated mortality. While obese patients have lower case fatality they are at much higher risk for ICU admission and as result suffer the highest burden of critical illness associated mortality in our region.

Predictors of early mortality in critically ill patients with acute kidney injury necessitating renal replacement therapy: A cohort study.
Reliable prediction of early mortality after initiation of renal replacement therapy (RRT) in critically ill patients may inform decision-making regarding this treatment. Our primary objective was to identify predictors of mortality within 2 days of starting RRT. ⋯ Higher SOFA was associated with 2-day mortality after RRT initiation and with hospital mortality. Discrimination in both models was modest.
