Background: In cancer cachexia the relationship between the tumour, its environment and the systemic inflammatory response is not clear. This study aims to examine this relationship in greater detail.
Methods: Host characteristics included the presence of a Systemic Inflammatory Response (SIR) as measured by Systemic Inflammatory Grade (SIG), sarcopenia (SMI) and myosteatosis (SMD) were measured. Categorical variables were analysed using χ test for linear-by-linear association, or χ test for 2 by 2 tables. Survival analysis was carried out using univariate and multivariate Cox regression.
Results: A total of 473 patients were included. Of these, 70.4% were over 65 years of age, 54.8% were male and 49.8% had an ASA grade of 1 or 2. Pathological examination showed that the majority of patients had a T3 (53.7%) or a T4 (34.0%) cancer and 73.0% had evidence of necrosis. A SIG score of 0 or 1 was present in 57.7% of patients. Tumour necrosis was associated with age (p < 0.01), tumour location (p < 0.01), T-stage (p < 0.001), margin involvement (p < 0.05), SIG (p < 0.001), SMI (p < 0.01), SMD (p < 0.05) and 5-year survival (p < 0.001). On multivariate survival analysis in patients with T3 cancers age (HR: 1.45 95% CI 1.13-1.86 p < 0.01), ASA grade (HR: 1.50 95% CI 1.15-1.95 p < 0.01) and SIG (HR: 1.28 95% CI 1.11-1.48 p < 0.001) remained independently associated with survival.
Conclusion: These results suggest that tumour necrosis and the subsequent SIR could result in profound changes in body composition and survival. Further pre-clinical and clinical work is required to prove causation.

SARS-CoV-2 is an oral pathogen that infects and replicates in mucosal and salivary epithelial cells, contributing to oral post-acute sequelae COVID-19 (PASC) and other oral and non-oral pathologies. While pre-existing inflammatory oral diseases provides a conducive environment for the virus, acute infection and persistence of SARS-CoV-2 can also results in oral microbiome dysbiosis that further worsens poor oral mucosal health. Indeed, oral PASC includes periodontal diseases, dysgeusia, xerostomia, pharyngitis, oral keratoses, and pulpitis suggesting significant bacterial contributions to SARS-CoV-2 and oral tissue tropism.

Fatigue is common among adults with cystic fibrosis (awCF) and may be associated with systemic inflammation. This study examines systemic inflammation, measured by C-reactive protein (CRP), and fatigue, assessed using the Cystic Fibrosis Questionnaire-Revised (CFQ-R) vitality domain, in individuals initiating elexacaftor/tezacaftor/ivacaftor (ETI) therapy. In a cohort of 61 awCF from St.

Chronic pain is a significant public health concern that diminishes patients' quality of life and imposes considerable socioeconomic costs. Effective pharmacological treatments for ongoing pain are limited. Recent studies have indicated that various models of chronic pain-such as neuropathic pain, inflammatory pain, and pain associated with cancer-have abnormal levels of long noncoding RNAs (lncRNAs).

Objectives: To compare explanted polypropylene mesh from those with and without mesh complications to determine the pathogenesis of the complications.
Methods: Between August 2019 and July 2020 66 participants attending Wesley and Royal Brisbane and Women's Hospital Urogynecology department with mesh complications and 15 undergoing repeat prolapse and/or continence surgery after prior polypropylene mesh implantation were included.

Background: The widespread use of gold nanoparticles (AuNPs) in consumer and medical products necessitates investigation into their potential developmental toxicity.
Aim Of The Work: This study investigated the systemic effects of in-utero AuNP exposure on developing male rat offspring, focusing on metabolic, organ-specific, and cellular pathways.
Materials And Methods: Pregnant rats were intravenously administered AuNPs (5, 10, 15, or 20 mg/kg) or saline from gestational day 1 to birth.
