Gastric duplication is a rare congenital disorder of the alimentary tract, and anemia is a rare presenting clinical sign of gastric duplication cysts (GDC). There are two reported cases of autoimmune hemolytic anemia as a paraneoplastic presentation of gastric duplication in the adult population, but there have not yet been any reported cases of this in childhood. We report the first case in the pediatric patient population: the case of GDC presenting as autoimmune hemolytic anemia in a 15-month-old girl.

As the learning health network known as the T1D Exchange Quality Improvement Collaborative (T1DX-QI) has expanded on a significant scale to provide care for more than 120,000 people since its inception in 2016, assessing the quality improvement (QI) culture and monitoring clinical outcome improvements of participating centers has become vital to understanding the network's progress and success. Centers participating in the T1DX-QI complete regular QI culture self-assessments to quantify four evidence-based areas of culture: QI team structure, QI foundation, QI capacity, and QI success. This study builds on a previous baseline analysis to demonstrate self-reported improvements in T1DX-QI centers' QI culture from 2021 to 2022 and summarizes QI successes experienced by participating centers.

Background: Although infections are a leading cause of morbidity and mortality among patients with multiple myeloma (MM), the epidemiology of invasive fungal disease (IFD) is less well characterized in this population than in other hematologic malignancies.

Methods: We conducted a nested 3:1 case-control study of IFD at a large MM referral center to identify risk factors for IFD in this population.

Results: In a cohort of 2960 patients, we identified 32 episodes of IFD among 31 patients between 01/2011 and 06/2019.

Cells are subjected to dynamic mechanical environments which impart forces and induce cellular responses. In age-related conditions like pulmonary fibrosis, there is both an increase in tissue stiffness and an accumulation of senescent cells. While senescent cells produce a senescence-associated secretory phenotype (SASP), the impact of physical stimuli on both cellular senescence and the SASP is not well understood.

Metabolic syndrome and its effect on immune cells in apical periodontitis- a narrative review.

Clin Oral Investig

January 2025

Faculty of Dentistry, University of Toronto, 124 Edward Street, Toronto, ON, M5G 1G6, Canada.

Objectives: Apical periodontitis (AP) is an inflammatory immune response in periapical tissues caused by microbial infections. Failure of root canal treatment or delayed healing is often due to intracanal or extra-radicular bacteria. However, beyond microbial factors, the patient's systemic health can significantly influence the progression and healing of AP.

Objective: When creating minimally invasive spine fusion constructs, accurate pedicle screw fixation is essential for biomechanical strength and avoiding complications arising from delicate surrounding structures. As research continues to analyze how to improve accuracy, long-term patient outcomes based on screw accuracy remain understudied. The objective of this study was to analyze long-term patient outcomes based on screw accuracy.

Background: As the use of robotics in total hip arthroplasty (THA) continues to gain popularity, differences in clinical outcomes when compared to manual techniques have remained unclear. This study aimed to compare postoperative complications between patients undergoing robotic-assisted techniques and manual THA for primary osteoarthritis at 90 days, 1 year, and 2 years.

Methods: Using an all-payer national database, we identified 405,048 patients who underwent either robotic-assisted or manual THA for primary osteoarthritis.

A hemangioma of the mitral valve and aortomitral curtain was incidentally discovered in an adolescent. The lesion was surgically excised, and the mitral valve was reconstructed with complete preservation of valvular function. Pertinent principles of multimodality imaging-based diagnosis and nuances of operative management of this rare, vascular tumor are discussed.

Introduction: Congenital diaphragmatic hernia (CDH) in the preterm population is increasingly common in the current era of fetal endoluminal tracheal occlusion (FETO) therapy. There remains a lack of clinical guidance for clinicians and surgeons regarding optimal management strategies for such infants. We aimed to describe our experience in managing preterm CDH in a single quaternary neonatal intensive care unit (NICU).

Context: Statin treatment lowers low-density lipoprotein (LDL) cholesterol thereby reducing cardiovascular risk. Meta-analyses of clinical trials report a higher risk of new-onset type 2 diabetes with statins. Current clinical evidence regarding effects of statins on insulin sensitivity and beta-cell function is limited.

Purpose: Vascular impairments, including reduced capillary density (CD), impaired autoregulation capacity (Reg), and elevated intraocular pressure (IOP), have been identified as significant contributors to glaucomatous disease. This study implemented a theoretical model to quantify the impact of these impairments on retinal blood flow and oxygenation as intraluminal pressure (Pa) is varied.

Methods: A theoretical model of the retinal vasculature was used to simulate reductions in CD by 10% (early glaucoma) and 30% to 50% (advanced glaucoma), a range in autoregulation capacity from 0% (totally impaired) to 100% (totally functional), and normal (15 mm Hg) and elevated (25 mm Hg) levels of IOP.

Background: Some prior studies have found that patients treated by female physicians may experience better outcomes, as well as lower healthcare costs than those treated by male physicians. Physician-patient sex concordance may also contribute to better patient outcomes. However, other studies have not identified a significant difference.

What does cancer screening have to do with tomato growing?

Clin Chem Lab Med

January 2025

Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital, Sinai Health System, Toronto, Canada.

Cancer screening is considered to be a major strategy for combatting cancer. The United States Preventive Services Task Force (USPSTF) recommends screening for five cancers, but the strength of evidence about the effectiveness of screening is limited. To gain insights into the efficacy of early detection requires prospective, blinded, placebo-controlled clinical trials with decades of follow-up and inclusion of millions of participants.

Optimizing Stem Cell Expansion: The Role of Substrate Stiffness in Enhancing Dental Pulp Stem Cell Quiescence and Regeneration.

J Endod

January 2025

Faculty of Dentistry, University of Toronto, Toronto, Ontario, Canada; Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Ontario, Canada; Department of Dentistry, Mt. Sinai Hospital, Toronto, ON, Canada. Electronic address:

Introduction: Quiescent stem cells exhibit unique self-renewal and engraftment abilities vital for regenerative therapies, but these diminish during ex vivo culture. This study investigates how substrate stiffness regulates the balance between dental pulp stem cell (DPSC) quiescence, activation, and senescence and explores the role of extracellular matrix stiffness in modulating DPSC fate via the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway.

Methods: Polydimethylsiloxane substrates with varying stiffness in 2D (2 kPa, 50 kPa) and 3D (50 kPa) were fabricated.

Spine Deform

January 2025

Department of Orthopedic Surgery, Mayo Clinic, 200 First Street S.W, Rochester, MN, 55906, USA.

Purpose: Non-fusion surgical options for pediatric scoliosis management such as vertebral body tethering (VBT) offer an alternative to spinal fusion. With this study, we aim to evaluate the postoperative outcomes in boys versus girls who have undergone VBT. Our hypothesis is that girls and boys will have similar outcomes by 2-year follow-up.
