This case study reports the results of a 12-year (2005-2016) follow-up study of two Olympic champion rowers. The rowers were prospective athletes at the junior level when the study began, and we monitored their relevant physiological and performance data annually. Our findings indicated that their V̇O2max gradually increased up to about 22 years of age and leveled off at a value of approximately 7 l·min(-1) with minimal fluctuations thereafter. However, the variables that directly influence the V̇O2max changed...

Normal fluid status (dry weight) can be identified by hydration markers established in the healthy population. The general population average could be influenced by age with its accompanying physiological changes and/or illness. The aims of this study were (1) to evaluate the effect of age and systolic blood pressure (SBP) on these markers; (2) to compare mean values of hydration markers as assessed by different bioimpedance techniques. Subjects from the general population (n  =  212, males 105, 57...

REVIEW
Ashley Russo, Vivian E Strong
The World Health Organization (WHO) has declared gastric carcinoma a global health concern and gastric cancer remains the third leading cause of cancer deaths worldwide. With the rising incidence of gastric cancer, a body of both retrospective and randomized data has emerged since the early 1990's evaluating the role of minimally invasive platforms in the management of gastric cancer. While Eastern studies have shown that the laparoscopic approach is safe and feasible for advanced gastric cancer in Eastern patients, it is not clear whether this is true for patients in the West...

Left atrial (LA) enlargement and dysfunction are markers of chronic diastolic dysfunction and an important predictor of adverse cardiovascular and cerebrovascular outcomes. Accordingly, accurate quantification of left atrial volume (LAV) and function is needed. In routine clinical cardiovascular magnetic resonance (CMR) imaging the biplane area-length method (Bi-ALM) is frequently applied due to time-saving image acquisition and analysis. However, given the varying anatomy of the LA we hypothesized that the diagnostic accuracy of the Bi-ALM is not sufficient and that results would be different from a precise volumetric assessment of transversal multi-slice cine images using Simpson's method...

OBJECTIVES: The diffusing capacity of the lung for carbon monoxide (DL CO ) is an indicator of lung damage. We sought to determine whether DL CO is associated with the aggressiveness of lung adenocarcinoma using histopathological indexes, such as tumour differentiation, scar grade, nuclear atypia and the mitotic index. METHODS: Fifty-seven patients with low DL CO (≤80% of predicted) and 466 patients with normal DL CO (>80% of predicted) who underwent R0 resection of lung adenocarcinoma between 2005 and 2012 were retrospectively reviewed...

United Network for Organ Sharing (UNOS) policies allows for ABO non-identical liver transplantation (LT) in candidates with Model for End-Stage Liver Disease (MELD) scores greater than 30. Previous studies showed ABO non-identical LT resulted in an 18% and 55% net gain in livers for B and AB candidates. These results suggested that the current liver ABO allocation policies may need refinement. There are, however, strong associations between ABO blood groups and race/ethnicity. We hypothesized that race/ethnicity is associated with ABO non-identical LT and that this is primarily influenced by recipient ABO status...
