Article Synopsis
- The study investigates the link between low body mass index (BMI) and mortality in older adults with sepsis in Japan, highlighting differences in body mass distributions between East Asian and Western populations.
- An analysis of 548 patients reveals that those with low BMI had a significantly higher 28-day mortality rate (21.4%) compared to those with normal (11.2%) and high BMI (14.5%).
- The findings indicate that low BMI is associated with a higher risk of mortality in sepsis patients, suggesting the need for careful monitoring of older adults with low BMI to improve their health outcomes.
Purpose: Disseminated intravascular coagulations (DIC), acute respiratory distress syndrome (ARDS), and acute kidney injury (AKI) are major organ dysfunctions that occur in patients with sepsis. This study aimed to elucidate the impact of these organ dysfunctions on mortality in patients with severe sepsis.
Material And Methods: A prospective observational study was performed in 10 ICUs to obtain data from patients with severe sepsis.
How does the camera assistant decide the zooming ratio of laparoscopic images? Analysis and implementation.

December 2008
An important factor for defining a good image during laparoscopic surgery is the zooming ratio, which corresponds to the depth of insertion of the laparoscope along its longitudinal axis. However, it is not clear how surgeons (camera assistants) decide the zooming ratio of laparoscopic images during surgery. Conventional automatic camera positioning systems define the zooming ratio "uniformly" based on simple heuristics.

A case of phlegmonous gastritis producing an intramural filling defect in the stomach is presented. Endoscopy showed edematous and reddened gastric mucosa with a mass lesion in the gastric body and antrum.

Case Report: A 67-year-old man was admitted to the hospital with acute severe abdominal pain. Selective angiography via a femoral puncture revealed a complete embolic occlusion distal to the first jejunal branch of the SMA.
Background: Retrospective studies using multivariate analysis of clinical and pathological features in gastric cancer have identified a number of high-risk, independent prognostic factors. In these clinical features, tumor size can be measured easily before or during the operation without the requirement of any special equipment, but its prognostic value in patients with gastric cancer is unclear. The aim of this study was to review the experience at our institution of gastric adenocarcinoma to determine the influence of tumor size on outcome.

The purpose of this study was to determine the factors that are predictive of early and late recurrences after gastrectomy.
Patients And Methods: We reviewed the hospital records of patients with hisotological proof of gastric cancer who were admitted to Sendai National Hospital during the period from 1985 to 1995.
