January 2025

Department of Medical Imaging, University of Arizona, 1501 N Campbell Ave, Tucson AZ 85724, USA; Banner University Medical Center Tucson, 1625 N Campbell Ave, Tucson AZ 85719, USA.

Breast magnetic resonance imaging (MRI) has the highest sensitivity for breast cancer detection compared to other breast imaging modalities such as mammography and ultrasound. As a functional modality, it captures the increased angiogenic activity of breast cancer through gadolinium-based contrast enhancement. Normal breast tissue also enhances, albeit in distinct patterns termed background parenchymal enhancement (BPE).

Electronic address:

A wide range of acute brain injuries, including both traumatic and non-traumatic causes, can result in elevated intracranial pressure (ICP), which in turn can cause further secondary injury to the brain, initiating a vicious cascade of propagating injury. Elevated ICP is therefore a neurological injury that requires intensive monitoring and time-sensitive interventions. Patients at high risk for developing elevated ICP undergo placement of invasive ICP monitors including external ventricular drains, intraparenchymal ICP monitors, and lumbar drains.

Behind the scenes of EQA - characteristics, capabilities, benefits and assets of external quality assessment (EQA).

Clin Chem Lab Med

January 2025

Department of Pathology and Laboratory Medicine, Canadian Microbiology Proficiency Testing Program (CMPT), University of British Columbia, Vancouver, Canada.

This is the first in a series of five papers that detail the role and substantial impact that external quality assessment (EQA) and their providers' services play in ensuring diagnostic (IVD) performance quality. The aim is to give readers and users of EQA services an insight into the processes in EQA, explain to them what happens before EQA samples are delivered and after examination results are submitted to the provider, how they are assessed, what benefits participants can expect, but also who are stakeholders other than participants and what significance do EQA data and assessment results have for them. This first paper presents the history of EQA, insights into legal, financing and ethical matters, information technology used in EQA, structure and lifecycle of EQA programs, frequency and intensity of challenges, and unique requirements of extra-examination and educational EQA programs.

The renin-angiotensin-aldosterone system (RAAS) is a complex regulator comprising hormones, proteins, and enzymes. The discovery of the RAAS and its pharmacological manipulation has been essential in the management of cardiovascular diseases, including hypertension. Beyond the benefits of hypertension, RAAS inhibition has implications for heart failure, atherosclerotic disease, and kidney disease.

In recent years, human mpox has made multiple resurges, prompting public health professionals to consider factors that lead to the increased risk for the reemergence of other orthopoxviruses. Due to the genetic similarity between orthopoxviruses, vaccinia vaccines used to prevent smallpox transmission are also indicated and have been used for mpox infection prevention and control. In this study, cross-reactive immunity for mpox was observed among individuals with self-reported history of smallpox vaccination.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Article Synopsis
  • The study investigates risk factors for proliferative vitreoretinopathy (PVR), a common complication after retinal detachment surgery.
  • A large patient database was analyzed, identifying systemic (like age, gender, and smoking) and ocular (such as trauma and previous eye conditions) factors that correlate with increased PVR risk.
  • The findings emphasize the importance of considering these risk factors in surgical planning and treatment to prevent PVR in patients with retinal detachment.

Sexual and reproductive health is an essential part of comprehensive medical care. As the field of medicine becomes more specialized and siloed and the diagnostic work-up in surgery more advanced, the risk of anchoring diagnoses and partitioning of care increases. Thus, the fundamentals of a complete patient history and review of each body system remain critical in ensuring that surgeons establish a broad differential diagnosis; provide comprehensive, well-rounded care to patients; and create opportunities for patient counseling and interventions.
