Article Abstract
Background: Little is known about the relation between perioperative inflammatory changes and long-term survival in cancer patients. The aim of the study was to assess the association of perioperative serum interleukin-6 (IL6) and tumor necrosis factor- (TNF) levels with the 5-year overall survival in locally advanced gastric cancer.
Methods: The 135 eligible patients in one center of Nanfang Hospital were retrieved from CLASS-01 trial (NCT01609309), an open-label, multicenter, randomized clinical noninferiority trial conducted at 14 centers in China. Serum IL6 and TNF levels were tested before surgery, and on postoperative day (POD) 1, POD3, and POD5, respectively, referring to IL6_0, IL6_1, IL6_3, and IL6_5 and TNF_0, TNF_1, TNF_3, and TNF_5. Kaplan-Meier methods and COX models were used for survival analysis.
Results: High levels of IL6_0 (≥3.67 pg/mL) and TNF_0 (≥14.8 pg/mL) presented worse disease-free survival (DFS) ( = 0.0057 for IL6_0 and = 0.0014 for TNF_0) and overall survival (OS) ( = 0.0021 for IL6_0 and = 0.0019 for TNF_0). Both high IL6_0 and high IL6_5 levels indicated worse prognosis than other combinations ( = 0.0045 for DFS and = 0.0022 for OS). In multivariate analysis, both high IL6_0 and high IL6_5 levels were significantly associated with poor DFS (HR = 4.29, 95% CI: 1.42-12.95, = 0.01) and OS (HR = 4.11, 95% CI: 1.35-12.49, = 0.013) after adjustment of tumor stage and TNF_0. Also, high IL6_5 level was identified as the independent-related factor for postoperative infectious complications (OR = 2.69, 95% CI: 1.03-7.01, = 0.043).
Conclusions: Perioperative high serum IL6 and TNF levels are negatively associated with 5-year survival outcomes in patients with locally advanced gastric cancer, indicating the potential survival benefits from perioperative anti-inflammatory treatment.

Aberrant activation of fibroblast growth factor receptors (FGFRs) plays a critical role in tumorigenesis across multiple cancer types, driving the development of various FGFR inhibitors. Despite clinical advances, therapeutic efficacy remains limited by the emergence of drug resistance, primarily mediated by gatekeeper mutations in FGFRs. To overcome this challenge, we designed and synthesized a novel series of 7-(1-methyl-1-indole-3-yl)-5-pyrrolo[2,3-]pyrazine derivatives as covalent pan-FGFR inhibitors targeting both wild-type and gatekeeper mutants.

Background: Alone time with health care providers is critical for adolescents, and several professional organizations recommend it. Alone time with providers promotes better utilization of health services, empowers adolescents to manage their health, and facilitates discussions on sensitive issues. However, only 40% of adolescents have private conversations with clinicians during visits.

One-year grants of up to $40,000 total were cofunded by this BWH-DOM program and by the applicant's BWH-DOM division to support health equity research or care innovation interventions. Recipients participated in a learning collaborative, which included community-building, health equity research and advocacy-related educational sessions, and midterm and final presentations.

The aim of this study was to assess current practices and compare outcomes for patients with locally advanced oesophageal squamous cell carcinoma across the UK and Ireland.
Methods: This was a retrospective multicentre cohort study of patients managed with curative intent for squamous cell carcinoma of the middle or distal oesophagus in 23 hospitals across the UK and Ireland.

Aquatic microorganisms typically inhabit a heterogeneous resource landscape, composed of localized and transient patches. To effectively exploit these resources, they have evolved a wide range of feeding strategies that combine chemotactic motility with active feeding flows. However, there is a notable lack of experimental studies that examine how these active flows shape resource fields to optimize feeding.
