Newly practicing early career radiologists face significant challenges as they onboard into their first attending role. One of the most difficult challenges is often aligning their expectations of their roles and responsibilities in the workplace with those of the institution or practice to which they now belong. This perspective will discuss some of these challenges and suggest potential approaches to assist new faculty in overcoming this alignment barrier to seamlessly integrate into their new work environment.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Circumferential minimally invasive surgery (cMIS) techniques in adult spinal deformity (ASD) surgery may reduce physiological burden compared with open technique, but their utility in octogenarians has not been previously assessed. METHODS:Operative ASD patients aged 80 years or older with complete baseline (BL) and 2-year postoperative radiographic and health-related quality of life data were assessed and compared by surgical technique: open vs cMIS. Propensity score matching aligned groups by BL Charlson Comorbidity Index (CCI), C7-S1 sagittal vertical axis, pelvic incidence minus lumbar lordosis mismatch, and C7 plumb line. BL and peri/postoperative factors were assessed using analysis of variance and Bonferroni-adjusted analysis of covariance while controlling for BL CCI and posterior fusion length. RESULTS:Thirty-four octogenarian ASD patients met inclusion criteria, of whom 29.4% underwent cMIS and 70.6% underwent open correction. cMIS patients were less likely to require surgical intensive care unit (10% vs 75%, P < .001) and had shorter hospital stays (4.6 vs 10.1 days, P = .013). Open patients reported higher Scoliosis Research Society-22 Appearance and Mental domain scores (both P < .005) and more frequently reached minimal clinically important difference in both domains by 2 years (P = .025, .024). cMIS patients more often required reoperation for radiographic sagittal imbalance by 2 years when controlling for CCI and levels fused (20.0% vs 8.3%, P < .001). No deaths occurred in either group by 2 years. CONCLUSION/CONCLUSIONS:In octogenarians undergoing ASD surgery, cMIS reduced physiological burden but had higher reoperation rates, whereas open surgery showed greater durability.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with marked clinical heterogeneity and a multifactorial pathogenesis. Environmental and lifestyle factors, including obesity, tobacco exposure, microbiome dysbiosis, dietary patterns, and plastic-associated endocrine disruptors, have all been linked to HS risk or disease severity. However, these exposures alone do not fully explain why only some individuals develop HS, why age at onset and severity vary substantially, or why disease occurs in patients without major identifiable environmental burden. In parallel, genetic studies have demonstrated that inherited susceptibility is a central component of HS pathogenesis. Rare loss-of-function variants in γ-secretase complex genes cause a small subset of familial, autosomal dominant HS, while genome-wide association studies have shown that population-level risk implicates pathways involved in epithelial differentiation, follicular biology, immune signaling, and cutaneous inflammation. Recent work further suggests that common and rare genetic risk may converge on shared biological mechanisms, including γ-secretase-related signaling. While nature vs. nurture arguments dichotomize genetic constitution and environmental exposures, current evidence supports a model in which genetic susceptibility interacts with environmental exposures to shape HS risk, clinical expression, and disease progression. In this review, we examine the evidence supporting both exposomic and genomic contributions to HS and argue that the disease is best understood as arising from their intersection rather than from either domain alone.

INTRODUCTION/BACKGROUND:Patients with a suspected high-consequence infectious disease (HCID), such as Ebola virus disease, may require routine laboratory testing to guide management. We assessed the capabilities of frontline hospitals and the barriers they face performing laboratory testing for patients with a suspected HCID. METHODS:A one-time confidential REDCap survey querying capabilities to safely perform laboratory tests that the Centers for Disease Control and Prevention considers critical for patients with a suspected HCID was sent to 95 institutions in Baltimore, MD, Boston, MA, New York City, NY, and Washington, DC, from January to May 2025. RESULTS:Fifty (53%) institutions responded, mostly teaching hospitals (96%), with 24% reporting prior experience evaluating a patient with suspected Ebola virus disease. While many hospitals could perform on-site blood gas (70%), hemoglobin/hematocrit (68%), and lactate (68%) tests on a suspected HCID patient, fewer could safely perform a chemistry panel (64%), a urinalysis (60%), a complete blood count with differential (56%), and a malaria rapid diagnostic test (RDT) (48%) on a suspected HCID patient. The five tests respondents most often considered extremely or very important were hemoglobin/hematocrit (91%), chemistry panel (90%), CBC with differential and platelet count (89%), malaria RDT (88%), and blood gas (88%). Reported barriers to performing routine laboratory testing included issues related to patient and staff safety, infection control, lack of appropriate space, and funding. CONCLUSIONS:Our survey identified several barriers to implementing safe laboratory testing. The inability to conduct these laboratory tests may result in delays in care when an HCID is suspected.

Working memory (WM), the transient storage and manipulation of information, is a cognitive function that can improve with training. Accumulating evidence suggests that sleep, particularly slow oscillations (SOs) that occur during nonrapid eye movement sleep, supports this improvement. Yet, how sleep and SOs in particular relate to neural processes supporting WM remains poorly understood. In this study, we investigated how WM-related neural activity evolves across nocturnal sleep and how these changes relate to neural processing during SOs. Participants performed a WM task during fMRI before and after sleep, with simultaneous EEG-fMRI capturing neural activity during the first 2.5 hr of sleep. Our results showed significant overnight changes in WM-related activity, characterized by reduced recruitment of the dorsal precuneus during WM encoding/maintenance phases and frontal regions during the retrieval phase of WM. In addition, sleep increased item-specific reinstatement in a sensory processing region during WM. This pattern of results suggests a combined influence of sleep on enhancing sensory reinstatement while reducing potential top-down control (i.e., reduced parietal and frontal activity). Critically, SO-related activity was directly linked to overnight activity changes: Stronger SO activation in the premotor cortex and ventromedial pFC predicted greater overnight reductions in WM-related activity, and multivoxel analyses in the ventral attention network revealed a parallel relationship. These findings suggest that SOs play a critical role in WM function by facilitating the reorganization of WM-related processing.

Extracranial-intracranial (EC-IC) bypass surgery remains an essential tool in the management of complex cerebrovascular disease, including chronic-ischemic hypoperfused territory as well as intracranial aneurysms requiring parent vessel sacrifice. Reliable postoperative surveillance of graft patency and hemodynamic function is central to long-term success. Sonographic imaging has evolved over four decades from indirect extracranial Doppler waveform analysis through intraoperative microvascular Doppler, quantitative duplex ultrasonography, and transcranial Doppler assessment of intracranial hemodynamics to the contemporary development of trans-sonolucent cranioplasty ultrasonography (TCUS). TCUS, enabled by the replacement of the autologous bone flap with an acoustically transparent polymethyl methacrylate (PMMA) cranioplasty, permits direct, real-time visualization of the anastomosis and surrounding intracranial vasculature. This can be performed at the bedside and in the outpatient setting, without radiation or contrast. Current evidence, drawn largely from small series and early multicenter experience, positions TCUS as a reliable and potentially cost-effective complement to digital subtraction angiography for serial bypass surveillance, though prospective validation remains needed. This review traces the full arc of sonographic bypass monitoring and addresses current evidence, technical considerations, established quantitative parameters, and directions for future investigation.

IMPORTANCE/UNASSIGNED:The decision to transfuse a patient with myocardial infarction (MI) and anemia at a higher vs lower hemoglobin threshold must consider the potential benefit of reduced risk of 30-day death or MI and the potential risk of heart failure. OBJECTIVES/UNASSIGNED:To estimate bayesian posterior risk differences and posterior probabilities that a liberal vs restrictive transfusion strategy is associated with reduced risk of 30-day death or MI and whether the probabilities exceed predefined thresholds. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:The Myocardial Ischemia and Transfusion (MINT) trial recruited adults from April 26, 2017, to April 14, 2023, who were hospitalized with MI and anemia at 144 sites in 6 countries. Statistical analysis was performed from July 31, 2024, to February 18, 2026. INTERVENTION/UNASSIGNED:The MINT trial randomized participants to a restrictive (transfuse if hemoglobin is <7 to 8 g/dL) or liberal (maintain hemoglobin at >10 g/dL) transfusion strategy. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Bayesian posterior risk differences were estimated for 30-day death or MI and for heart failure using 3 prior beliefs regarding the treatment strategies: noninformative, liberal strategy superiority, or restrictive strategy superiority. RESULTS/UNASSIGNED:The mean (SD) age of the 3504 participants was 72.1 (11.6) years and 1911 (54.5%) were men. Compared with the restrictive strategy, the risk of 30-day death or MI with the liberal strategy was 1.4% (95% credible interval, -0.8% to 3.5%) to 2.4% (95% credible interval, 0.3%-4.6%) lower, depending on prior beliefs. The probability that the liberal strategy was associated with a lower risk of 30-day death or MI ranged from 89.1% to 98.8%, and the probability that a liberal strategy was associated with at least 1 less death or MI per 100 treated was between 62.7% and 90.4%. Conversely, the risk of heart failure with the liberal strategy was 0.2% (95% credible interval, -1.6% to 1.2%) to 0.6% (95% credible interval, -2.0% to 0.8%) higher compared with the restrictive strategy, depending on prior beliefs. The probability that the liberal strategy was associated with a higher risk of heart failure ranged from 60.6% to 80.0%, and the probability that a liberal strategy was associated with at least 1 more heart failure event per 100 treated was between 13.3% and 29.3%. CONCLUSIONS AND RELEVANCE/UNASSIGNED:This post hoc analysis of a randomized clinical trial of patients with MI and anemia suggests that a liberal transfusion strategy was associated with a lower risk of 30-day death or MI, outweighing the increased risk of heart failure. Consistent with guideline recommendations and according to patients' values and clinician risk assessment, a liberal transfusion strategy may be reasonable.

PURPOSE/OBJECTIVE:This study aimed to examine associations of bisphenol and phthalate exposure with arterial stiffness among women of reproductive age. METHODS:Participants include 637 adult women enrolled in the New York University Children's Health and Environment Study (NYU CHES), a prospective pregnancy cohort. The concentrations of eight bisphenols and 22 phthalate metabolites were quantified in up to three spot urine samples. Primary outcomes included brachial artery distensibility (BrachD) and carotid-femoral pulse wave velocity (cfPWV) as measures of peripheral and central arterial stiffness, respectively, along with blood pressure assessed at repeated study visits up to seven years from exposure measures. Associations between averaged, log2-transformed, creatinine-standardized chemical concentrations and subclinical vascular outcomes of interest were examined using linear mixed-effects models. RESULTS:In covariate-adjusted models, a doubling of bisphenol A was positively associated with BrachD (0.09%/mmHg, 95% confidence interval [CI] = 0.02, 0.16), a doubling of bisphenol S was negatively associated with mean arterial pressure (MAP) (-0.52 mmHg, 95% CI = -0.98, -0.05), a doubling of di(2-ethylhexyl) phthalate (DEHP) metabolites was negatively associated with diastolic blood pressure (DBP) (-0.81 mmHg, 95% CI = -1.38, -0.23) and MAP (-0.83 mmHg, 95% CI = -1.45, -0.21), and a doubling of antiandrogenic phthalate metabolites was associated with 0.62 mmHg lower DBP (95% CI = -1.22, -0.03) and 0.66 mmHg lower MAP (95% CI = -1.30, -0.02). CONCLUSION/CONCLUSIONS:These findings suggest that routine exposure to bisphenols and DEHP may be associated with vasorelaxation, potentially related to these chemicals' estrogenic and/or antiandrogenic effects.

PURPOSE/OBJECTIVE:Optical coherence tomography angiography (OCTA) has enabled detailed in vivo imaging of macular neovascularization (MNV) in neovascular age-related macular degeneration (nAMD), leading to a proliferation of morphological descriptive terms. This scoping review aimed to systematically map the existing literature on OCTA-based MNV morphology and evaluate its correlation with disease activity. METHODS:A systematic literature search covering publications through 2025 was performed. After screening 2,445 titles and obtaining 60 full texts, 43 studies were included. Data on morphological terminology, study design, and correlation with disease activity were extracted and synthesized. RESULTS:The included studies, encompassing a total of 2,712 eyes, identified a vast and heterogeneous lexicon of qualitative descriptors, including terms such as "medusa," "sea-fan," and "glomerulus", characterized by significant terminological overlap and inconsistent definitions across studies. Inconsistent, low-certainty associations between specific OCTA morphologies and MNV activity were identified across studies, with findings limited by significant methodological heterogeneity. The evidence for these patterns as reliable biomarkers of disease activity is weak and often contradictory, and several studies were found to use OCTA features to define activity, creating circular arguments that undermine their conclusions. CONCLUSION/CONCLUSIONS:The current terminology for OCTA morphology in nAMD is fragmented and inconsistently applied. The link between these patterns and disease activity is poorly established, severely limiting their clinical utility. These findings highlight a need for a standardized, consensus-based framework for describing and interpreting OCTA findings in nAMD.
