Article Synopsis
  • This study investigates the use of retrospective gated computed tomography (RGCT) to measure three-dimensional (3D) left atrial (LA) motion and strain, addressing limitations of traditional 2D imaging techniques that can underestimate heart mechanics.
  • The research involved 30 patients with heart failure and reduced ejection fraction (HFrEF), comparing those with atrial fibrillation (AF) to those without and found that AF is associated with significantly lower global and regional LA strains.
  • Results highlighted that patients with HFrEF and AF not only had reduced reservoir strains but also greater dyssynchrony in regional strains, particularly marked in the inferior wall, suggesting impaired heart function linked to AF.

Background/aims: Abdominal X-rays are frequently requested by clinicians in the Aberdeen Royal Infirmary acute medical initial assessment unit.

Method: The proportion of indicated abdominal X-rays requested within 24 hours of admission was retrospectively examined. This process was repeated after displaying an educational poster with the Royal College of Radiologists guidelines (cycle 2) and a graded assertive communication poster (cycles 3 and 4); a tool to enable junior doctors to challenge inappropriate requests for abdominal X-rays from seniors.

Background: requires training and validation to standards expected of humans. We developed an online platform and established the Unity Collaborative to build a dataset of expertise from 17 hospitals for training, validation, and standardization of such techniques.

Methods: The training dataset consisted of 2056 individual frames drawn at random from 1265 parasternal long-axis video-loops of patients undergoing clinical echocardiography in 2015 to 2016.

In the field of cardio-oncology, it is well recognised that despite the benefits of chemotherapy in treating and possibly curing cancer, it can cause catastrophic damage to bystander tissues resulting in a range of potentially of life-threatening cardiovascular toxicities, and leading to a number of damaging side effects including heart failure and myocardial infarction. Cardiotoxicity is responsible for significant morbidity and mortality in the long-term in oncology patients, specifically due to left ventricular dysfunction. There is increasing emphasis on the early use of biomarkers in order to detect the cardiotoxicity at a stage before it becomes irreversible.

Background: Splenosis is defined as the process by which tissue from the spleen disseminates through the body and grows in an ectopic location following trauma or a splenectomy. Visceral sites of splenosis are rare.

Case Summary: We report a case of intrahepatic splenosis in a 57-year-old man with a history of trauma over 40 years ago who initially presented with chest pain.

Background: Nutcracker syndrome (NCS) describes left renal vein compression between the superior mesenteric artery and the aorta. Although uncommon, it is an important diagnosis due to the important morbidity associated with it, including the risk of chronic kidney disease from long-term left renal vein (LRV) hypertension and the risk of LRV thrombosis.

Methods: This article reviews the literature on NCS, particularly with respect to the diagnostic accuracy of different imaging modalities and the success rates, complications, and long-term follow-up data associated with various surgical interventions.

Antibiotic use in intensive care units (ICUs) can promote antimicrobial resistance. Outbreaks of multi-resistant bacteria significantly affect patient outcomes and delivery of care. Antibiotic stewardship programmes (ASPs), combining root-cause analyses and multi-faceted prevention strategies, are necessary, often at significant cost and time.

The quest for possible targets for the development of novel analgesics has identified the activation of the cannabinoid type 1 (CB1) receptor outside the CNS as a potential means of providing relief from persistent pain, which currently constitutes an unmet medical need. Increasing tissue levels of the CB1 receptor endogenous ligand N-arachidonoylethanolamine (anandamide), by inhibiting anandamide degradation through blocking the anandamide-hydrolysing enzyme fatty acid amide hydrolase, has been suggested to be used to activate the CB1 receptor. However, recent clinical trials revealed that this approach does not deliver the expected relief from pain.
