External Validation of a 5-Factor Risk Model for Breast Cancer-Related Lymphedema.

JAMA Netw Open

January 2025

Institute of Medical Science, Temerty Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada.

Importance: Secondary lymphedema is a common, harmful side effect of breast cancer treatment. Robust risk models that are externally validated are needed to facilitate clinical translation. A published risk model used 5 accessible clinical factors to predict the development of breast cancer-related lymphedema; this model included a patient's mammographic breast density as a novel predictive factor.

Outcomes of a Population-Based Congenital Cytomegalovirus Screening Program.

JAMA Pediatr

January 2025

Department of Pediatrics, Children's Hospital of Eastern Ontario, University of Ottawa, Ottawa, Ontario, Canada.

Importance: Detection of congenital cytomegalovirus (cCMV) infection has previously relied on targeted screening programs or clinical recognition; however, these approaches miss most cCMV-infected newborns and fail to identify those infants who are asymptomatic at birth but at risk for late-onset sensorineural hearing loss.

Objective: To determine the feasibility of using routinely collected newborn dried blood spots (DBS) in a population-based cCMV screen to identify infants at risk for hearing loss and describe outcomes of infants screened.

Design, Setting, And Participants: This diagnostic study of a population-based screening program in Ontario, Canada, took place from July 29, 2019, to July 31, 2023.

Purpose: Mesothelin (MSLN) is highly expressed in high grade serous/ endometrioid ovarian cancers (HGOC). Anetumab ravtansine (AR) is an antibody drug conjugate directed at MSLN antigen with a tubulin polymerization inhibitor. We assessed safety, activity and pharmacokinetics of the combination AR/bevacizumab (Bev) (ARB) versus weekly paclitaxel (wP)/Bev (PB) in patients with platinum resistant/refractory HGOC (prrHGOC).

Rationale: In critically ill patients receiving invasive mechanical ventilation, switching from controlled to assisted ventilation is a crucial milestone towards ventilator liberation. The optimal timing for switching to assisted ventilation has not been studied.

Objectives: Our objective was to determine whether a strategy of early as compared to delayed switching affects the duration of invasive mechanical ventilation, ICU length of stay, and mortality.

J Trauma Acute Care Surg

January 2025

From the Division of Urology, Department of Surgery (S.K., J.B.M.), University of Utah School of Medicine, Salt Lake City, Utah; Department of Surgery (G.T.T.), Scripps Memorial Hospital La Jolla, La Jolla, California; Division of Urology, Department of Surgery (R.M.), University of Toronto, Toronto, Ontario, Canada; Department of Radiology (J.A.G.), University of Washington, Harborview Medical Center, Seattle, Washington; Department of Surgery (C.C.), UC Health Medical Center of the Rockies, Loveland, Colorado; Department of Surgery (K.L.K.), University of California San Francisco Fresno, Fresno, California; Department of Surgery (M.C.), Case Western Reserve University, Cleveland, Ohio; Shock Trauma Center (R.A.K.), University of Maryland School of Medicine, Baltimore, Maryland; Division of Acute Care and Regional General Surgery (N.L.W., B.L.Z.), University of Wisconsin-Madison School of Medicine and Public Health, Madison, Wisconsin; and Scott Department of Urology (M.C.), Baylor College of Medicine, Houston, Texas.

The American Association for the Surgery of Trauma initially published the organ injury scaling for the kidney in 1989, which was subsequently updated in 2018. This current American Association for the Surgery of Trauma kidney organ injury scaling update incorporates the latest evidence in diagnosis and management of renal trauma and is based upon a multidisciplinary consensus. These changes reflect the near universal use of computed tomography for renal trauma evaluation and the widespread adoption of conservative management across all grades of renal trauma.

Sad Art Gives Voice to Our Own Sadness.

Cogn Sci

January 2025

Program in Cognitive Science and Department of Philosophy, Yale University.

People tend to show greater liking for expressions of sadness when these expressions are described as art. Why does this effect arise? One obvious hypothesis would be that describing something as art makes people more likely to regard it as fictional, and people prefer expressions of sadness that are not real. We contrast this obvious hypothesis with a hypothesis derived from the philosophical literature.

Introduction: Medulloblastoma (MB) is the most common malignant childhood brain tumor. Molecular subgrouping of MB has become a major determinant of management in high-income countries. Subgrouping is still very limited in low- and middle-income countries (LMICs), and its relevance to management with the incorporation of risk stratification (low risk, standard risk, high risk, and very high risk) has yet to be evaluated in this setting.

Neutrophil-to-lymphocyte ratio at diagnosis predicts colonoscopic activity in pediatric inflammatory bowel diseases (pIBD).

Clin Transl Gastroenterol

January 2025

Division of Pediatric Gastroenterology and Nutrition, Department of Pediatrics, University of Alberta, Edmonton, Alberta, Canada.

Background: Neutrophil-to-lymphocyte ratio (NLR) is a novel biomarker studied in several autoimmune diseases including inflammatory bowel diseases (IBD) in adults, but poorly characterized in pediatric IBD (pIBD). We aimed to primarily investigate the relationship between NLR and pIBD endoscopic disease severity. We also examined whether NLR predicted hospitalization, surgery, and therapy response by 52 weeks.

Background And Purpose: Prolonged length of stay (LOS) following a stroke is associated with unfavorable clinical outcomes. Factors predicting LOS in medium vessel occlusion (MeVO), impacting up to 40% of acute ischemic stroke (AIS) cases, remain underexplored. This study aims to investigate the predictors of LOS in AIS-MeVO.

Precision, or personalized, medicine aims to stratify patients based on variable pathogenic signatures to optimize the effectiveness of disease prevention and treatment. This approach is favorable in the context of brain disorders, which are often heterogeneous in their pathophysiological features, patterns of disease progression and treatment response, resulting in limited therapeutic standard-of-care. Here we highlight the transformative role that human induced pluripotent stem cell (hiPSC)-derived neural models are poised to play in advancing precision medicine for brain disorders, particularly emerging innovations that improve the relevance of hiPSC models to human physiology.

The effects of aerobic exercise and heat stress on the unbound fraction of caffeine.

Front Physiol

January 2025

Human Physiology Research Unit, Faculty of Kinesiology and Physical Education, University of Toronto, Toronto, ON, Canada.

Introduction: The fraction of drug circulating in the blood that is not bound to plasma proteins ( ) is considered pharmacologically active since it readily binds to its receptor. evidence suggests that changes in temperature and pH affect the affinity of drug binding to plasma proteins, resulting in changes in . In light of the well-established effects of exercise on body temperature and blood pH, we investigated whether an increase in blood temperature and decrease in pH facilitated through passive heating and exercise translated to a change in the of caffeine.

Introduction: Cardiac computerized tomographic angiography (CCTA) is perceived as a non-invasive tool for assessment of coronary vessel anatomy. Feature tracking echocardiography has recently emerged as a tool for assessment of regional and global left ventricular function. We aimed to explore the applicability of echocardiographic strain on CCTA cine clips and assess whether global and regional strain parameters are associated with the extent of coronary stenosis.

The pathogenesis of Crohn's disease (CD) remains unknown. The current working theory is that genetic susceptibility influences host-microbe interactions, resulting in chronic inflammation. Case-control studies fail to explain the triggers or pathogenesis of the disease, notably due to confounding factors in patients with established disease.

Purpose: Corneal dysmorphologies (CDs) are typically classified as either regressive degenerative corneal dystrophies (CDtrs) or defective growth and differentiation-driven corneal dysplasias (CDyps). Both eye disorders have multifactorial etiologies. While previous work has elucidated many aspects of CDs, such as presenting symptoms, epidemiology, and pathophysiology, the genetic mechanisms remain incompletely understood.
