Plasma arginine metabolites in health and chronic kidney disease.

Background: Elevated plasma asymmetric and symmetric dimethylarginine (ADMA and SDMA) are risk factors for chronic kidney disease (CKD) and cardiovascular disease. Using plasma cystatin C (pCYSC)-based estimated glomerular filtration rate (eGFR) trajectories, we identified a cohort at high risk of poor kidney-related health outcomes amongst members of the Dunedin Multidisciplinary Health and Development Study (DMHDS). We therefore examined associations between methylarginine metabolites and kidney function in this cohort.

The Sheen Paajanen grOin Recommended Treatment 'SPoRT' score for groin pain.

Introduction: Evaluating groin pain still evades many clinicians at times as they have difficulty determining the cause of pain when no true hernia exists. This study's aim was to evaluate a simple and novel scoring system which is reproducible, to help determine whether conservative measures or surgery is recommended for the management of groin pain attributable to inguinal disruption.

Material & Methods: A retrospective analysis of all patients from 2018 to 2020 that underwent surgery or conservative management for inguinal disruption with at least a 1-year follow-up were evaluated.

Acetaminophen Metabolites on Presentation Following an Acute Acetaminophen Overdose (ATOM-7).

Acetaminophen (APAP) is commonly taken in overdose and can cause acute liver injury via the toxic metabolite NAPQI formed by cytochrome (CYP) P450 pathway. We aimed to evaluate the concentrations of APAP metabolites on presentation following an acute APAP poisoning and whether these predicted the subsequent onset of hepatotoxicity (peak alanine aminotransferase > 1,000 U/L). The Australian Toxicology Monitoring (ATOM) study is a prospective observational study, recruiting via two poison information centers and four toxicology units.

The reorganisation of emergency general surgery services during the COVID-19 pandemic in the UK: outcomes of delayed presentation, socio-economic deprivation and Black, Asian and Minority Ethnic patients.

Introduction: The COVID-19 pandemic is a global public health emergency. Lockdown restrictions and the reconfiguration of healthcare systems to accommodate an increase in critical care capacity have had an impact on 'non-COVID' specialties. This study characterises the utilisation of emergency general surgery (EGS) services during the UK lockdown period at a university teaching hospital with a catchment population that represents one of the most deprived and ethnically diverse areas in the UK.
