Renovascular hypertension - a primer for the radiologist.

Renovascular hypertension (RVHT) is an important cause of secondary hypertension, accounting for approximately 75% of cases. This pictorial review describes the imaging modalities used to diagnose RVHT, including ultrasound, computed tomography angiography, and magnetic resonance angiography, provides their benefits and limitations, and explores the imaging findings, diagnostic criteria, and management of multiple causes of RVHT. Atherosclerosis is the most common cause of RVHT, particularly in older individuals, while fibromuscular dysplasia is more prevalent in younger females.

Iron starvation results in up-regulation of a probable siderophore transporter.

The response of the haloarchaeal model organism to iron starvation was analyzed at the proteome level by data-independent acquisition mass spectrometry. Cells grown in minimal medium with normal iron levels were compared to those grown under low iron conditions, with samples being separated into membrane and cytoplasmic fractions in order to focus on import/export processes which are frequently associated with metal homeostasis. Iron starvation not only caused a severe retardation of growth but also altered the levels of many proteins.

Engaging the AQ10 to Predict Professional Burnout or Poor Work-Related Psychological Wellbeing Among Anglican Clergy in Wales.

The ten-item Autism Spectrum Quotient (AQ10) is a self-report instrument originally designed to identify referrals for professional diagnosis for Autism Spectrum Disorders (ASD). Recent studies suggest that this instrument may also be tapping more generalised affective disorders. Working with this interpretation, this study examines the predictive power of the AQ10 to account for additional variance, after personal and personality factors have been taken into account, on the two scales of the Francis Burnout Inventory.

Pulmonary artery pseudoaneurysms: a single-center experience of endovascular occlusion.

The technique and outcomes of pulmonary artery pseudoaneurysm (PAP) embolization was retrospectively evaluated in 13 patients undergoing 14 PAP embolizations between January 2014 and September 2023. The etiology of the PAP was iatrogenic (4/13), tumor (3/13), chronic lung (2/13), idiopathic (2/13) and mycotic (2/13). Clinical presentation was massive hemorrhage (6/13), incidental (4/13), and non-massive hemoptysis (3/13).

[Pestiviruses in sheep and goats in Austria: Options for integration into the bovine viral diarrhea (BVDV) monitoring program].

After the successful eradication of the bovine viral diarrhea virus (BVDV) in cattle in Austria, the risk of infections with the border disease virus (BDV) remains. Both viruses belong to the pestivirus genus. BDV infections lead to false-positive results in BVDV surveillance.

Common femoral arterial access and arteriography in infants: Principles, pearls, and pitfalls.

Infant femoral arterial access is an essential part of interventional procedures, hemodynamic monitoring, and support of critically ill patients. Due to small luminal diameter, superficial location, mobility, and increased risk of vasospasm, dissection, and thrombosis, femoral artery access in the infant is a technically demanding procedure. The purpose of this manuscript is to describe an approach to successful common femoral arterial access and arteriography in infants including common pearls and pitfalls.

Grading Abdominal Trauma: Changes in and Implications of the Revised 2018 AAST-OIS for the Spleen, Liver, and Kidney.

According to the Centers for Disease Control and Prevention, trauma is the leading cause of fatal injuries for Americans aged 1-44 years old and the fourth leading overall cause of death. Accurate and early diagnosis, including grading of solid organ injuries after blunt abdominal trauma (BAT), is crucial to guide management and improve outcomes. The American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) is the most widely accepted BAT scoring system at CT both within the United States and internationally, and its uses include stratification of injury severity, thereby guiding management, and facilitation of clinical research, billing, and coding.

Non-invasive candidate protein signature predicts hepatic venous pressure gradient reduction in cirrhotic patients after sustained virologic response.

Background And Aims: A reduction in hepatic venous pressure gradient (HVPG) is the most accurate marker for assessing the severity of portal hypertension and the effectiveness of intervention treatments. This study aimed to evaluate the prognostic potential of blood-based proteomic biomarkers in predicting HVPG response amongst cirrhotic patients with portal hypertension due to Hepatitis C virus (HCV) and had achieved sustained virologic response (SVR).

Methods: The study comprised 59 patients from two cohorts.

Natural language processing in radiology: Clinical applications and future directions.

Natural language processing (NLP) is a wide range of techniques that allows computers to interact with human text. Applications of NLP in everyday life include language translation aids, chat bots, and text prediction. It has been increasingly utilized in the medical field with increased reliance on electronic health records.

Intestinal Epithelial Digestive, Transport, and Barrier Protein Expression Is Increased in Environmental Enteric Dysfunction.

Environmental enteric dysfunction (EED) is characterized by malabsorption and diarrhea that result in irreversible deficits in physical and intellectual growth. We sought to define the expression of transport and tight junction proteins by quantitative analysis of duodenal biopsies from patients with EED. Biopsies from Pakistani children with confirmed EED diagnoses were compared to those from age-matched North American healthy controls, patients with celiac disease, and patients with nonceliac disease with villous atrophy or intraepithelial lymphocytosis.

Registry of Aortic Diseases to Model Adverse Events and Progression (ROADMAP) in Uncomplicated Type B Aortic Dissection: Study Design and Rationale.

Purpose: To describe the design and methodological approach of a multicenter, retrospective study to externally validate a clinical and imaging-based model for predicting the risk of late adverse events in patients with initially uncomplicated type B aortic dissection (uTBAD).

Materials And Methods: The Registry of Aortic Diseases to Model Adverse Events and Progression (ROADMAP) is a collaboration between 10 academic aortic centers in North America and Europe. Two centers have previously developed and internally validated a recently developed risk prediction model.

Therapeutic US Applications for the Abdomen and Pelvis.

US and MRI-guided therapeutic US (TUS) can aid in the treatment of prostate, liver, and pancreatic cancer, as well as uterine fibroids and osseous metastases, and understanding the selection and optimization of treatment strategies is essential to furthering TUS advances and innovations.

Inter-observer variability of expert-derived morphologic risk predictors in aortic dissection.

Objectives: Establishing the reproducibility of expert-derived measurements on CTA exams of aortic dissection is clinically important and paramount for ground-truth determination for machine learning.

Methods: Four independent observers retrospectively evaluated CTA exams of 72 patients with uncomplicated Stanford type B aortic dissection and assessed the reproducibility of a recently proposed combination of four morphologic risk predictors (maximum aortic diameter, false lumen circumferential angle, false lumen outflow, and intercostal arteries). For the first inter-observer variability assessment, 47 CTA scans from one aortic center were evaluated by expert-observer 1 in an unconstrained clinical assessment without a standardized workflow and compared to a composite of three expert-observers (observers 2-4) using a standardized workflow.

Sequelae of Eating Disorders at Imaging.

Although eating disorders are common, they tend to be underdiagnosed and undertreated because social stigma tends to make patients less likely to seek medical attention and less compliant with medical treatment. Diagnosis is crucial because these disorders can affect any organ system and are associated with the highest mortality rate of any psychiatric disorder. Because of this, imaging findings, when recognized, can be vital to the diagnosis and management of eating disorders and their related complications.
