DEELE-Rad: exploiting deep radiomics features in deep learning models using COVID-19 chest X-ray images.

Purpose: Deep learning-based radiomics techniques have the potential to aid specialists and physicians in performing decision-making in COVID-19 scenarios. Specifically, a Deep Learning (DL) ensemble model is employed to classify medical images when addressing the diagnosis during the classification tasks for COVID-19 using chest X-ray images. It also provides feasible and reliable visual explicability concerning the results to support decision-making.

Do patients with minimally displaced distal radial fractures need a plaster cast?

Traditionally, patients with a fracture of the distal radius are treated in a cast if they do not require surgery. If the fracture requires manipulation, the cast is moulded to hold the reduction and maintain normal anatomical alignment during healing. However, is a cast necessary for patients whose fracture does not require manipulation? Removable splints are an alternative treatment option.

Haemodynamic measurements during hip hemiarthroplasty surgery for hip fracture.

Aims: There is compelling evidence for the use of cemented hip hemiarthroplasty for displaced intracapsular hip fractures; however, the risks of cement are well reported and in rare cases may be associated with haemodynamic collapse. It is therefore important to improve our understanding of haemodynamic instability, intraoperative monitoring, and strategies to reduce the risk to patients.

Methods: We measured arterial blood pressure using the LiDCO Continuous Non-invasive Arterial Pressure (CNAP) finger cuff during surgery in patients enrolled in the WHiTE 5 trial randomized to cemented or modern uncemented hip hemiarthroplasty at a single recruiting site.

Placentas From SARS-CoV-2 Infection During Pregnancy Exhibit Foci of Oxidative Stress and DNA Damage.

Problem: COVID-19 during pregnancy is linked to increased maternal morbidity and a higher incidence of preterm births (PTBs), yet the underlying mechanisms remain unclear. Cellular senescence, characterized by the irreversible cessation of cell division, is a critical process in placental function, and its dysregulation has been implicated in pregnancy complications like PTB. Senescence can be induced by various stressors, including oxidative stress, DNA damage, and viral infections.

Do Factors Influencing Acceptance of Kidney Stone Formers as Donors Predict Subsequent Stone Events?

Purpose: This study aimed to assess whether kidney stone burden and risk factors at the time of kidney donor evaluation were associated with a symptomatic stone event post-donor evaluation.

Methods: We identified adults evaluated at Mayo Clinic (two sites) (2000-2011) for living kidney donation and had either a personal history or radiological evidence of kidney stone disease. We analyzed demographics, stone risk factors, stone number/size, and the committee's donation decision and reasons.
