Article Abstract
Objectives: The aim of this study was to examine safety outcomes in patients referred for transesophageal echocardiograms (TEEs) for tricuspid valve disease.
Design: Retrospective observational study.
Setting: Single quaternary referral center specializing in structural heart disease.
Participants: One hundred five patients referred for TEE for tricuspid valve disease between July 2022 and June 2023.
Interventions: This study was not interventional, but assessed the safety of TEE.
Methods And Main Results: The primary outcome was a composite of hypotension (mean arterial pressure [MAP] < 60 mmHg); use of epinephrine, norepinephrine, or calcium chloride; aborted studies due to documented clinical instability; emergent intubation; hospitalization or escalation of care post-TEE; oropharyngeal or gastrointestinal injury; or cardiac arrest. Secondary outcomes were 30-day cardiovascular mortality, all vasopressor use, and time spent per TEE. The primary outcome was noted in 32 patients (30.5%). The rate of cardiac arrest was 2.9% (3/105). Hypotension (MAP < 60 mmHg) was noted in 30 patients, with 7 patients needing hospitalization after TEE. No patients had oropharyngeal or gastrointestinal injury. There was a greater prevalence of moderate to severe right ventricular (RV) dilation (77% vs 53%; p = 0.022) and moderately to severely decreased RV function (48% vs 25%; p = 0.023) in patients who met the primary outcome. Both RV fractional area change (37.9% vs 29.8%; p = 0.003) and tricuspid annular plane systolic excursion (1.84 cm vs 1.45 cm; p = 0.002) were lower on baseline transthoracic echocardiogram.
Conclusions: Patients with severe tricuspid regurgitation had a high prevalence of adverse events when undergoing TEE. Further studies are needed to compare these outcomes with other groups undergoing diagnostic TEE and delineate what risk factors may place these patients at greater risk.

YOLOv12 Algorithm-Aided Detection and Classification of Lateral Malleolar Avulsion Fracture and Subfibular Ossicle Based on CT Images: A Multicenter Study.

Background: Lateral malleolar avulsion fracture (LMAF) and subfibular ossicle (SFO) are distinct entities that both present as small bone fragments near the lateral malleolus on imaging, yet require different treatment strategies. Clinical and radiological differentiation is challenging, which can impede timely and precise management. On imaging, magnetic resonance imaging (MRI) is the diagnostic gold standard for differentiating LMAF from SFO, whereas radiological differentiation on computed tomography (CT) alone is challenging in routine practice.

Rationale And Objectives: Double expression lymphoma (DEL) is an independent high-risk prognostic factor for primary CNS lymphoma (PCNSL), and its diagnosis currently relies on invasive methods. This study first integrates radiomics and habitat radiomics features to enhance preoperative DEL status prediction models via intratumoral heterogeneity analysis.
Materials And Methods: Clinical, pathological, and MRI imaging data of 139 PCNSL patients from two independent centers were collected.
National Update on Healthcare-Associated Infections in Iran for 2023-Based on the Iranian Nosocomial Infections Surveillance (INIS) System.

Background: Healthcare-associated infections (HCAIs) pose a serious threat to healthcare systems. Accurately determining the incidence of HCAIs is crucial for planning and implementing efficient interventions, as they are associated with a wide range of challenges. The objective of this study was to assess and update the incidence rates of HCAIs in Iran in 2023, using data from the Iranian Nosocomial Infection Surveillance (INIS) system, a nationwide hospital-based surveillance program.

Acute ischemic stroke (AIS) remains a leading cause of mortality and long-term disability globally, with survivors at high risk of recurrent stroke, cardiovascular events, and post-stroke dementia. Statins, while widely used for their lipid-lowering effects, also possess pleiotropic properties, including anti-inflammatory, endothelial-stabilizing, and neuroprotective actions, which may offer added benefit in AIS management. This article synthesizes emerging evidence on statins' dual mechanisms of action and evaluates their role in reducing recurrence, improving survival, and mitigating cognitive decline.
