Excessive weight is connected with an increased risk of certain life-threatening diseases. However, some evidence shows that among patients with chronic diseases such as heart failure (HF) chronic kidney disease (CKD) and COPD, increased weight is paradoxically associated with a decreased risk of mortality. This counterintuitive phenomenon is referred to as the obesity paradox. The obesity paradox has been mostly observed among certain cohorts of patients with HF, but not specific to patients in the Intensive Care Unit (ICU) setting. This paper studies the relationship between obesity and mortality of ICU patients with and without HF and presents evidence supporting the existence of this paradox. The results provide helpful insights for developing more patient-centric care in ICUs. Additionally, we use both the MIMIC-II and (recently available) MIMIC-III databases, for which few comparative studies exist to date. We demonstrate an aspect of consistency between the databases, providing a significant step towards validating the use of the newly announced MIMIC-III in broader studies.

Introduction: Stroke is one of the common causes of mortality. The length of stay (LOS) for a stroke is a quality indicator and affects mortality. However, there are no large studies evaluating the LOS in an acute inpatient setting for stroke patients, mainly hematological and social parameters.

Purpose: This study investigates the complex relationship between body mass index (BMI) and bladder cancer outcomes, utilizing Taiwan's national database. Bladder cancer remains a significant health concern, especially in Taiwan, prompting a comprehensive retrospective analysis to explore the impact of obesity on survival outcomes.
Materials And Methods: A meticulous exclusion process, based on Taiwan National Health Insurance System Database, refined the initial dataset of 15,086 bladder cancer patients to 10,352.
Body mass index and waist-to-height ratio effect on mortality in non-alcoholic fatty liver: revisiting the obesity paradox.

Purpose: Emerging research indicates that individuals with non-alcoholic fatty liver disease (NAFLD) who carry excess weight have similar or even higher survival rates than their normal-weight counterparts. This puzzling "obesity paradox" may be attributed to underlying biases. To explore this phenomenon, we examined data extracted from the third National Health and Nutrition Examination Survey (NHANES) III, which spanned from 1988-1994.

Evolutionary perspectives on obesity have been dominated by genetic frameworks, but plastic responses are also central to its aetiology. While often considered a relatively modern phenomenon, obesity was recorded during the Palaeolithic through small statuettes of the female form (Venus figurines). Even if the phenotype was rare, these statuettes indicate that some women achieved large body sizes during the last glacial maximum, a period of nutritional stress.

Objective: To investigate the relationship between obesity and postoperative mortality in the context of high procedural complexity and comorbidity burden.
Background: The "obesity paradox" suggests better postoperative outcomes in patients with higher body mass index (BMI), despite obesity's associated health risks. Research remains scarce on the influence of procedural complexity and comorbidities on the obesity-postoperative mortality relationship.
