Tumor-Stroma Ratio is an independent predictor for overall survival and disease free survival in gastric cancer patients.
Despite different prognostic factors have been already studied, patients undergoing potentially curative resection for gastric cancer, still have a poor outcome. There is therefore the need to identify novel prognostic factors. Recently, Tumor-Stroma Ratio (TSR) was proven to be associated with prognosis in different types of cancers. Aim of this study was to evaluate the prognostic value of TSR in gastric cancer patients. ⋯ TSR is an independent marker of poor prognosis in patients with gastric cancer that should be readily incorporated into routine clinical pathology reporting. Identification of sensitive markers for patients who had undergone curative gastrectomy and who are at high risk of recurrence could provide useful information for planning follow-up after surgery or intensive and or/targeting adjuvant chemotherapy.

Review Meta Analysis Comparative StudyCT- versus MRI-based patient-specific instrumentation for total knee arthroplasty: A systematic review and meta-analysis.
To determine whether computed tomography (CT) or magnetic resonance imaging (MRI) is more suitable for the patient-specific instrumentation (PSI) systems for total knee arthroplasty (TKA). ⋯ The current limited evidence suggests that MRI-based PSI systems exhibit higher accuracy for TKA regarding the coronal limb axis than CT-based PSI systems. However, well-designed studies comparing CT-versus MRI-based PSI systems for TKA are warrant to confirm these results before widespread use of this technique can be recommended.

ReviewSurgeons' and surgical trainees' acute stress in real operations or simulation: A systematic review.
Acute stress in surgery is ubiquitous and has an immediate impact on surgical performance and patient safety. Surgeons react with several coping strategies; however, they recognise the necessity of formal stress management training. Thus, stress assessment is a direct need. Surgical simulation is a validated standardised training milieu designed to replicate real-life situations. It replicates stress, prevents biases, and provides objective metrics. The complexity of stress mechanisms makes stress measurement difficult to quantify and interpret. This systematic review aims to identify studies that have used acute stress estimation measurements in surgeons or surgical trainees during real operations or surgical simulation, and to collectively present the rationale of these tools, with special emphasis in salivary markers. ⋯ There is a broad spectrum of acute mental stress assessment tools in the surgical field and simulation and salivary biomarkers have recently gained popularity. There is a need to maintain a consistent methodology in future research, towards a deeper understanding of acute stress in the surgical field.
