In the British Army, ground close combat roles have opened to women, however, they must pass the newly developed, gender-neutral Role Fitness Tests for Soldiers (RFT(S)). Due to physiological differences between sexes, training that optimally prepares both sexes for military occupational demands and the RFT(S) is needed. The purpose of this study was to determine the efficacy of a 12-week periodized strength and power programme with concurrent interval training on RFT(S) performance and determine if performance adaptations differed between sexes.

Article Synopsis
  • A post-hoc analysis of the RAINBOW trial investigated the efficacy of ramucirumab and paclitaxel (RAM+PAC) in patients with liver metastasis (LM) versus those without, highlighting that around 40% of advanced gastric cancer patients have LM, which worsens prognosis.
  • In this study involving 665 patients, those with LM experienced earlier disease progression, but RAM+PAC treatment improved overall survival (OS) and progression-free survival (PFS) for both groups, with better outcomes observed in the LM+ group.
  • Despite similar adverse events across both groups, the analysis found no significant predictive relationship between biomarkers and treatment efficacy, suggesting that RAM
