Background The Woven EndoBridge (WEB) device is an effective treatment for wide‐neck aneurysms (WNA). This study aims to identify and compare anatomical and procedural factors that predicts the aneurysm occlusion, both adequate and inadequate after WEB device treatment. Methods A systematic review and meta‐analysis were conducted using PubMed, Embase, Scopus, and Web of Science, including studies up to October 25, 2024. Data on angiographic outcomes of WEB occlusion were extracted and analyzed using R version 4.4.2 Results Nine studies (790 patients) were included. Female patients were 1.64 times more likely to achieve adequate occlusion than males (OR: 1.64, 95% CI: [1.06, 2.52], p = 0.026). Regular‐shaped aneurysms had a 2.44‐fold higher likelihood of adequate occlusion compared to irregular ones (OR: 0.41, 95% CI: [0.23, 0.74]). Aneurysm neck size was significantly smaller in the adequate occlusion group (3.9 mm vs. 4.4 mm, MD: ‐0.48 mm, 95% CI: [‐0.78, ‐0.18], p = 0.002). Maximum aneurysm diameter was also smaller in the adequate occlusion group (5.7 mm vs. 6.8 mm, MD: ‐1.13 mm, 95% CI: [‐1.69, ‐0.57], p < 0.001). Aneurysm height was also significantly lower than the inadequate occlusion group (5.4 mm vs. 6.3 mm, MD: ‐0.92 mm, 95% CI: [‐1.55, ‐0.29], p = 0.004). Conclusion Smaller aneurysm dimensions, regular shape, and female gender were associated with higher adequate occlusion rates after WEB treatment. These findings may guide patient selection strategies for optimizing aneurysm occlusion. Further high‐quality studies are needed to confirm these associations. image image

Glioblastoma (GBM) is an aggressive brain tumor that often progresses despite resection and treatment. Timely and continuous assessment of GBM progression is critical to expedite secondary surgery or enrollment in clinical trials. However, current progression detection requires costly and specialized MRI examinations, which, in the absence of new symptoms or signs, are usually scheduled every 2–3 months. Here, we hypothesized that changes in daily activity are associated with GBM growth and disease progression. We found that wheel-running activity in GBM-bearing mice declined as tumors grew and preceded weight loss and circadian breakdown by over a week. Temozolomide treatment in the morning, but not evening, significantly reduced tumor size and restored daily locomotion in mice. In a pilot study of 6 patients with GBM wearing an actigraphy watch, wrist movement provided a feasible and continuous longitudinal indicator of daily activity with 1-minute resolution. After tumor resection and radiation, daily activity declined in 2 patients 19 and 55 days before detection of progression by MRI but did not change for the 4 patients with stable disease. These results suggest that daily activity tracking using wearable devices may serve as a real-time indicator and potential monitoring tool for GBM progression and treatment efficacy.

Abstract Immune checkpoint inhibitors (ICIs) have limited benefit in recurrent high-grade astrocytoma (rHGA), largely because the blood–brain barrier and a profoundly immunosuppressive tumor microenvironment prevent T cells from infiltrating. Laser interstitial thermal therapy (LITT) is a minimally invasive, cytoreductive procedure that can “heat up” these otherwise “cold” tumors and sensitize them to ICIs. In this tri-institutional Phase 1/randomized Phase 2 trial (NCT02311582), bevacizumab- and immunotherapy-naïve rHGA patients were initially randomized 1:1 to either LITT followed by pembrolizumab (LITT+PEM) or non-LITT surgery (biopsy or resection) followed by pembrolizumab (NLS+PEM). Phase 2 participants enrolled at a second recurrence—with several already at a third recurrence—underscoring the advanced disease stage of this cohort. After 21 patients, randomization was halted when contemporaneous evidence showed limited benefit from adjuvant ICIs alone, and the remaining 24 patients received only LITT+PEM. In the 21-patient intent-to-treat cohort, LITT+PEM extended median OS to 21.3 months with 54% alive at 18 months (OS18) versus 6.7 months with 12.5% OS18 with NLS+PEM (HR 0.29; 95% CI, 0.01–0.88; p=0.021). Median PFS was 7.8 versus 2.2 months (HR 0.3; 95% CI, 0.10–0.87; p=0.020). Among 39 per-protocol patients, LITT+PEM yielded a median OS of 11.8 months with 42% OS18 versus 5.2 months with 0% OS18 for NLS+PEM (HR 0.17; 95% CI, 0.06–0.49; p=0.0002), and a median PFS of 4.5 versus 1.6 months (HR 0.21; 95% CI, 0.08–0.56; p=0.0006). The combination was well tolerated. Immune profiling revealed that LITT triggers early activation of non-classical monocytes—a change associated with improved survival—while subsequent pembrolizumab unleashes robust CD8⁺ T cell proliferation and clonal expansion. Long-term LITT+PEM survivors developed coordinated memory T-cell responses, whereas shorter-surviving patients exhibited stagnant memory pools and exhausted phenotypes. Together, these results demonstrate that LITT plus pembrolizumab is safe, overcomes rHGA’s immunosuppressive barrier, and mobilizes robust anti-tumor immunity.

Abstract Advocacy has long been at the core of the infectious diseases (ID) field, with clinicians and researchers advocating to ensure patients can access the care they need on an individual and global scale. The Infectious Diseases Society of America Training Program Directors’ (PD) Committee met in 2024 and discussed ways that advocacy is and should be incorporated into fellowship training, as well as highlighted the role PDs play in advocating for their trainees. Policies with a negative impact on ID clinical care, public health, and research underscore the importance of mobilizing the field of ID to advocate for the patients and communities we serve, as well as for ourselves. This paper presents ideas generated at this meeting and is meant to serve as a reference for ID PDs, as well as the wider ID community, as a call to action for teaching and participating in advocacy work.

Background Patients with cardiohepatic syndrome are at higher risk of adverse outcomes in the cardiac intensive care unit. We hypothesized that cardiohepatic syndrome phenotypes would exhibit differences in their clinical and transthoracic echocardiogram hemodynamic profiles, portending a higher risk of mortality. Methods We included unique CICU patients with an admission diagnosis of heart failure from 2007 to 2018 with available data for 1 or more admission liver function tests. Echocardiographic variables were extracted from patients who had a transthoracic echocardiogram within 1 day of admission. We assigned patients to 1 of 4 mutually exclusive cardiohepatic syndrome phenotype groups: normal, hepatocellular, cholestasis, and combined. Results We included 3992 CICU patients; 2483 had an available transthoracic echocardiogram. Patients with cholestasis had more right ventricular systolic dysfunction and congestion, whereas those with hepatocellular injury had more left ventricular systolic dysfunction and poor forward flow; hemodynamics and biventricular function were worst in the combined group. In‐hospital mortality occurred in 14.6% and was higher for patients with cholestasis or hepatocellular injury, especially those with greater extent/severity and worse biventricular function or poor hemodynamics. After adjustment, only the group with hepatocellular injury (adjusted odds ratio [OR], 1.35 [95% CI, 1.04–1.75], P =0.03) and the combined group (adjusted OR, 1.75 [95% CI, 1.30–2.34], P <0.001) remained at higher risk. One‐year mortality was highest in the combined group (adjusted hazard ratio [HR], 1.29 [95% CI, 1.10–1.51], P =0.002). Conclusions Cardiohepatic syndrome phenotypes are associated with distinct echocardiographic profiles. Patients with the combined cardiohepatic syndrome phenotype were at highest risk of mortality, particularly if this was combined with poor cardiac function.

PURPOSE Despite international medical graduates (IMGs) accounting for up to one third of all practicing oncologists in the United States, and nearly half of fellowship trainees, little is known about their contributions to presentations at international oncology meetings. Therefore, we investigated the representation of IMGs in invited faculty roles at the ASCO Annual Meeting as a representative example. METHODS Presentation data from ASCO 2022 and 2023 Annual Meetings were obtained from program guides. We collected presentation-level and speaker-level variables of invited faculty roles and original research. Speakers were categorized as American medical graduate (AMG), IMG, non–US-based, or non-MD (Doctor of Medicine). Univariable and multivariable analyses assessed factors influencing selection for invited faculty roles. RESULTS A total of 2,590 presentations by 2,109 unique speakers were reviewed, including primary research presenters and invited faculty. Among the 1,352 presentations by AMGs, 30% were primary research and 70% were invited faculty roles. For the 374 presentations by IMGs, 41% were primary research and 59% were invited faculty roles. Notably, first-author IMGs were significantly less likely to receive invited faculty roles relative to their primary research output compared with first-author AMGs (adjusted odds ratio, 0.69 [95% CI, 0.53 to 0.90]; P = .006), even when accounting for academic rank, presumed sex, and year. CONCLUSION Relative to IMGs' original research output, IMGs appear to receive fewer invitations for ASCO Annual Meeting invited faculty roles compared with AMGs. Our findings suggest potential underrepresentation and under-recognition of IMGs in these roles, despite their contributions to the oncology workforce in the United States.

AimsPolymyalgia rheumatica (PMR) is a chronic autoimmune disorder that mainly affects older adults. Pulmonary disease in PMR is rare but may be under‐recognized and pathological descriptions thereof are few. We aimed to characterize diffuse parenchymal lung disease (DPLD) in PMR.Methods and resultsInstitutional archives were searched for patients having PMR and DPLD with lung tissue sampling. After excluding cases with infection, concomitant rheumatoid arthritis, or smoking‐related DPLD only, 11 patients (9 women, median age 75 years) were enrolled. Clinical history and pathology slides were reviewed. One of the 11 patients (9%) had concomitant giant cell arteritis; the remaining patients had no other rheumatological diseases. All had been treated for PMR with immunosuppression, and most presented years later (median 6 years) with non‐specific respiratory symptoms. Radiographically, bilateral ground‐glass opacities and reticulation were typical and were usually lower lobe predominant. Histologically, fibrosis was seen in 8 of 11 (73%) patients and was unclassifiable in four; non‐specific interstitial pneumonia was encountered in three patients, and usual interstitial pneumonia was seen in only one case. Evidence of acute lung injury occurred in 9 (82%) patients, including three with acute lung injury only, usually manifesting as organizing pneumonia. Diffuse alveolar haemorrhage was seen in four cases (29%), including two patients with haemoptysis and capillaritis.ConclusionsOur data corroborate prior reports of clinically significant DPLD in some patients with PMR. Histopathological findings mirror other rheumatological disorders and include diffuse alveolar haemorrhage with capillaritis. Additional studies are warranted to clarify the association between PMR and DPLD.

ABSTRACTBackground and AimsBowel diaries are used to characterize the severity of fecal incontinence (FI) but have not been adequately validated for this purpose. Our aims were to validate a new bowel diary and to compare the characteristics of FI as assessed with a bowel diary and a validated questionnaire.MethodsIn this four‐center prospective study, patients with a history of FI and asymptomatic controls completed a 28‐day bowel diary and validated questionnaires to evaluate bowel habits and FI, quality of life related to FI (FIQoL), and PROMIS scales for anxiety, depression, and self‐efficacy.ResultsAmong 59 participants with FI and 29 asymptomatic controls, the bowel diary was 97% sensitive and 93% specific for distinguishing between FI participants and controls. Over 28 days, FI participants experienced an average [SD] of 31.1 [50.7] FI episodes, consisting of staining (12.6 [14.9]), some stool (12.5 [20.3]), or a full bowel movement (4.4 [8.5]). Correlations between the questionnaire and diary were statistically significant for frequency (Spearman ρ = 0.5, p < 0.001), amount (ρ = 0.4, p < 0.001), and awareness of FI (ρ = 0.3, p = 0.04). In 71% of participants, there was agreement between the consistency of FI as reported in the questionnaire and the diary. More severe FI was associated with poorer FIQoL (p = 0.002). Anxiety, depression, and self‐efficacy scores did not significantly affect the agreement between the frequency of FI reported in the diary and questionnaire.ConclusionThis bowel diary effectively discriminates between healthy participants and those with FI. There is significant, albeit modest, agreement between the characteristics of FI recorded with a diary and a questionnaire.
