ABSTRACT Anesthetic technique affects surgical outcomes and oncological prognosis. Recognizing the critical role of surgery in cancer treatment, this narrative review aims to improve anesthesiology practices for cancer patients by evaluating actions that positively influence outcomes. Anesthesiologist experience helps guide technique choice in complex cases. Decisions should be customized based on the type of surgery and patient condition, as different techniques can significantly impact results. The expertise of the entire team at specialized centers further enhances outcomes.

Abstract Medical imaging is undergoing a transformation driven by the advent of new, highly effective, machine learning techniques paired with increases in computational capabilities (Cheng et al. 2021; Gilson et al. 2023; Almeida et al. 2024; Krishna et al. 2024). These advanced algorithms have the potential to improve disease detection, diagnosis, prognosis, and treatment outcomes. However, the complexity of machine learning models, the large amounts of curated and annotated data required by some methods, and the potential for bias and error make it challenging for individuals to safely and effectively leverage these methods (Lin et al. 2024; Guo et al. 2024; Xu et al. 2024; Linguraru et al. 2024; Wood et al. 2019). To address these challenges, the American Association of Physicists in Medicine (AAPM), American College of Radiology (ACR), Radiological Society of North America (RSNA), and Society for Imaging Informatics in Medicine (SIIM) have worked together to develop a syllabus detailing a recommended set of competencies for medical imaging professionals interacting with these systems. This guide is aimed at four different personas: users of AI systems, purchasers of AI systems, individuals who provide clinical expertise during the development of AI systems (“clinical collaborators”), and developers of AI systems.1 This is a syllabus, not a curriculum, and is intentional in this scope. Recognizing that individuals may benefit from different presentations of the same material, this work enumerates a series of relevant competencies but does not prescribe, nor offer, a method of instruction (Schuur, Rezazade Mehrizi, and Ranschaert 2021; Garin et al. 2023). By addressing the task‐specific demands of each role, this guide will enable medical imaging professionals to utilize machine learning systems more safely and effectively, ultimately improving patient care and outcomes.

PURPOSE Ziftomenib—a potent, highly selective, oral menin inhibitor—was well tolerated and demonstrated encouraging clinical activity as monotherapy for relapsed/refractory NPM1 -mutated ( NPM1 -m) and KMT2A -rearranged AML in the KOMET-001 phase I trial. METHODS In the registration-enabling phase II part of KOMET-001, patients with relapsed/refractory NPM1 -m AML received ziftomenib 600 mg once daily. The primary end point was the rate of complete remission with full hematologic recovery (CR)/CR with partial hematologic recovery (CRh). RESULTS From January 26, 2023, to May 13, 2024, 92 patients (median age, 69 years [range, 33-84]) were treated. The primary end point was met, with a CR/CRh rate of 22% (95% CI, 14 to 32; P = .0058); 61% were negative for measurable residual disease. Overall response rate was 33% (95% CI, 23 to 43), with a median duration of 4.6 months (95% CI, 2.8 to 7.4). Prespecified subgroup analyses showed comparable CR/CRh regardless of previous therapy, including venetoclax, or type of comutations. Median overall survival was 6.6 months (95% CI, 3.6 to 8.6). Common grade ≥3 treatment-emergent adverse events were febrile neutropenia (26%), anemia (20%), and thrombocytopenia (20%). Differentiation syndrome occurred in 25% of patients (15% grade 3; no grade 4-5) and was manageable with protocol-defined mitigation. Three patients (3%) discontinued treatment because of ziftomenib-related adverse events. CONCLUSION Ziftomenib demonstrated significant clinical benefit and deep responses in patients with heavily pretreated, relapsed/refractory NPM1 -m AML. Ziftomenib was well tolerated with a safety profile consistent with previous studies, including manageable differentiation syndrome, lack of clinically significant QTc prolongation, and low rates of myelosuppression.

We present the case of a 12-year-old female who presented with progressive back pain and was found to have a localized mass in the lumbar spine. The resected tissue was characterized by epithelioid cells with a papillary appearance and high mitotic activity. Initial immunohistochemical analysis was consistent with a diagnosis of atypical meningioma. However, comprehensive molecular profiling detected a CRTC1::NCOA2 fusion with a novel NCOA2 gene rearrangement, leading to a revised descriptive diagnosis of epithelioid mesenchymal neoplasm with CRTC1::NCOA2 fusion. This specific fusion has only been reported in 2 other cases involving mesenchymal neoplasms of the palate and urinary bladder. While CRTC1 is frequently associated with MAML2 fusion in mucoepidermoid carcinomas, NCOA2 rearrangements occur in a variety of solid and hematologic malignancies. There is a paucity of information on the prognostic relevance of these fusion partners. This is the first reported case of a CRTC1::NCOA2 fusion in a pediatric patient with a spinal cord malignancy. The mechanistic significance and prognostic implications of this fusion will be discussed.

ABSTRACT Background Sodium–glucose co-transporter 2 inhibitors (SGLT2is) are emerging as an essential part of the standard of care for proteinuria in patients with chronic kidney disease. To date, no study has specifically evaluated the effects of body mass index (BMI) on the antiproteinuric efficacy of SGLT2is. Here we report the impact of BMI on the antiproteinuric efficacy of SGLT2is in non-diabetic patients with glomerular diseases. Methods This is a retrospective, multicentre, international observational cohort study that included non-diabetic patients with biopsy-proven glomerular disease and proteinuria >0.5 g/24 h who received SGLT2is between 2016 and 2023. Laboratory values, including proteinuria and estimated glomerular filtration rate (eGFR), were obtained at baseline and after 3–6 months. Changes in laboratory values over time were analysed using the paired signed-rank test. Results A total of 300 patients met the inclusion criteria. The median age was 51.82 years [interquartile range (IQR) 41–62.65], 64.7% were male and 92.7% were white. The most common glomerular disease was immunoglobulin A nephropathy (40.3%). The median eGFR was 52.26 ml/min/1.73 m2 (IQR 36.41–74.01), the median proteinuria was 1.60 g/24 h (IQR 1.15–2.91) and the median serum albumin was 4.08 g/dl (IQR 3.80–4.30). Proteinuria reduction after SGLT2i initiation was significant only in overweight and obese patients (P < .001 versus 0.18). Patients with normal BMI did not experience the expected early decrease in eGFR (P = .16). Conclusions SGLT2is are ineffective in proteinuria reduction in patients with a BMI <25 kg/m2, which contrasts with the significant proteinuria reduction in overweight and obese patients with glomerulopathies.

AbstractBackgroundVEXAS syndrome is an autoinflammatory disease caused by somatic UBA1 mutations on the X chromosome, predominantly affecting men.ObjectiveTo characterize VEXAS syndrome in women and to compare the features of VEXAS syndrome between sexes.MethodsWe conducted an international, multicenter study, including 12 women and 301 men with genetically confirmed VEXAS syndrome. Data were collected using a standardized case report form. Bone marrow analyses and molecular investigations were performed locally.ResultsClinical features, age at onset, UBA1 mutation type, variant allele frequency, and mortality were comparable between sexes. Acquired X monosomy was found in 6/8 tested women. Additional clonal mutations were present in 3/5 tested women. Three additional UBA1‐mutated women without typical inflammation are described separately.ConclusionVEXAS syndrome affects women with clinical features similar to men, supporting the need for UBA1 testing in women with compatible presentations. X monosomy is common but not universal, suggesting alternative pathogenic mechanisms.

Abstract Repetitive head impacts are associated with structural brain changes and an increased risk for chronic traumatic encephalopathy, a progressive neurodegenerative disease that can only be diagnosed after death. Chronic traumatic encephalopathy is defined by the abnormal accumulation of phosphorylated tau protein, particularly at the depths of the superior frontal sulci, suggesting that sulcal morphology may serve as a relevant structural biomarker. Contact sport athletes, such as former football players, are at elevated risk due to their prolonged exposure to repetitive head impacts. Cortical atrophy linked to underlying tau accumulation may result in shallower and wider sulci, potentially making sulcal morphology an imaging marker for identifying individuals at risk for this disease. This study investigated sulcal morphological differences in former football players and examined associations with age, football-related exposure, clinical diagnosis of traumatic encephalopathy syndrome, levels of certainty for chronic traumatic encephalopathy pathology, neuropsychological performance, and positron emission tomography imaging using flortaucipir. We analysed structural magnetic resonance imaging data from 169 male former football players (mean age 57.2 (8.2) years, range 45–74) and 54 age-matched, unexposed asymptomatic male controls (mean age 59.4 (8.5) years, range 45–74). Sulcal depth and width were quantified using the CalcSulc, focusing on two regions in each hemisphere commonly affected by chronic traumatic encephalopathy pathology: the superior frontal and occipitotemporal sulci. Generalized least squares models were used to assess group differences and interactions with age and football exposure variables, including age of first exposure, total years played, and cumulative head impact exposure. An analysis of covariance evaluated relationships between sulcal morphology, clinical measures, and flortaucipir uptake, adjusting for age, race, body mass index, education, imaging site, apolipoprotein E4 status, and total intracranial volume. Former football players demonstrated significantly shallower sulcal depth in the left superior frontal sulcus compared to unexposed controls. Earlier age of first exposure and longer football careers were associated with greater widening of the left occipitotemporal sulcus. Higher cumulative head impact exposure was linked to reduced sulcal depth in the left superior frontal region. However, sulcal morphology was not associated with clinical diagnosis, levels of certainty, neuropsychological test performance, or flortaucipir imaging. These findings suggest that sulcal morphology may reflect cumulative exposure to repetitive head impacts, particularly in brain regions vulnerable to chronic traumatic encephalopathy pathology. Future ante- and post-mortem validation studies are needed to determine whether sulcal morphology can serve as a reliable in vivo biomarker of risk.

Hypertension is the single most important modifiable risk factor for preventable disability and death worldwide and disproportionately affects socially disadvantaged populations. We face a paradox—blood pressure control is low and recent trends suggest it is even declining, despite the availability of inexpensive and effective therapies. A variety of barriers on the system, patient, and healthcare provider side hinder effective drug-based risk factor management. Clinical inertia represents a major barrier on the clinician side, as well as workload and limited education. Common barriers on the patient side include limited English proficiency, low health literacy, and nonadherence with misaligned incentives, limited resources, lack of structured clinical pathways, and reimbursement issues. New innovations in the field of RNA-targeted therapies and device-based interventions could prevent and potentially even cure diseases previously designated as chronic health conditions, such as hypertension. Such novel therapies could potentially overcome several major barriers to effective treatment, including nonadherence. Drug development of novel, long-acting treatments requires consideration of specific clinical trial design aspects, including safety collection, benefit: risk assessment, the development and assessment of novel, qualitative surrogate end points, such as time-in-therapeutic range, the use of representative trial settings as well as the definition of standard of care in placebo-controlled trials, which should be of reasonably high-quality allowing for credible evaluation of effectiveness. Here, we provide an overview on barriers to effective treatment and a framework for trials assessing novel treatments for cardiovascular disease risk factors, including early and broad implementation programs.
