ABSTRACTRobotic‐assisted bronchoscopy (RAB) has improved lung nodule evaluation, but its feasibility to biopsy aortopulmonary lymph nodes remains underexplored. This study explored the safety and effectiveness of RAB for sampling aortopulmonary lymph nodes suspected of malignancy. We conducted a literature review on RAB for aortopulmonary lymph node biopsy and present a case of a patient with a history of malignancy. Using the Ion Endoluminal System, we navigated to the anterior segment of the left upper lobe to access a subaortic lymph node in a patient with a history of mantle cell lymphoma. Biopsy confirmed disease recurrence. Our literature review identified seven patients who underwent RAB to assess aortopulmonary lymph nodes, with most findings showing small‐cell lung cancer. Our study reports an 88% diagnostic yield, and no complications associated with the procedure. RAB is a safe and effective approach for biopsying aortopulmonary lymph nodes.

ImportanceThere are no useful treatments to prevent the development of severe complications of liver cirrhosis. Simvastatin and rifaximin have shown beneficial effects in liver cirrhosis.ObjectiveTo assess whether simvastatin combined with rifaximin improves outcomes in patients with decompensated cirrhosis.Design, Setting, and ParticipantsDouble-blind, placebo-controlled, phase 3 trial conducted among patients with decompensated cirrhosis in 14 European hospitals between January 2019 and December 2022. The last date of follow-up was December 2022.InterventionsPatients were randomly assigned to receive simvastatin, 20 mg/d, plus rifaximin, 1200 mg/d (n = 117), or identical-appearing placebo (n = 120) for 12 months in addition to standard therapy, stratified according to Child-Pugh class B or C.Main Outcomes and MeasuresThe primary end point was incidence of severe complications of liver cirrhosis associated with organ failure meeting criteria for acute-on-chronic liver failure. Secondary outcomes included transplant or death and a composite end point of complications of cirrhosis (ascites, hepatic encephalopathy, variceal bleeding, acute kidney injury, and infection).ResultsAmong the 237 participants randomized (Child-Pugh class B: n = 194; Child-Pugh class C: n = 43), 72% were male and the mean age was 57 years. There were no differences between the 2 groups in terms of development of acute-on-chronic liver failure (21 [17.9%] vs 17 [14.2%] patients in the treatment and placebo groups, respectively; hazard ratio, 1.23; 95% CI, 0.65-2.34; P = .52); transplant or death (22 [18.8%] vs 29 [24.2%] patients in the treatment and placebo groups, respectively; hazard ratio, 0.75; 95% CI, 0.43-1.32; P = .32); or development of complications of cirrhosis (50 [42.7%] vs 55 [45.8%] patients in the treatment and placebo groups, respectively; hazard ratio, 0.93; 95% CI, 0.63-1.36; P = .70). Incidence of adverse events was similar in both groups (426 vs 419; P = .59), but 3 patients in the treatment group (2.6%) developed rhabdomyolysis.Conclusions and RelevanceThe addition of simvastatin plus rifaximin to standard therapy does not improve outcomes in patients with decompensated liver cirrhosis.Trial RegistrationClinicalTrials.gov Identifier: NCT03780673

OBJECTIVE Spinal cord cavernous malformations (SCCMs) are rare vascular malformations with a capricious prognosis. Given the eloquent nature of the spinal cord, considerable surgical morbidity may be encountered. Therefore, conservative management has emerged as a valid alternative, especially for incidental lesions diagnosed on ubiquitous imaging. The aim of this systematic review and meta-analysis was to evaluate the safety and efficacy of surgical versus conservative management of SCCMs. METHODS Following PRISMA guidelines, this study included articles published in full-text form comparing the outcomes following conservative and surgical management of SCCMs. Collected variables included the total number of patients, spine level, resection, myelotomy, follow-up duration, bleeding, motor weakness, pain, bladder and/or bowel dysfunction, and neurological improvement or deterioration after discharge. The primary outcome of interest was long-term functional outcome. RESULTS Eleven articles comprising 515 patients were included, of whom 343 (66.6%) underwent resection and 172 (33.4%) were managed conservatively. Patients who underwent surgery were more likely to have preoperative motor deficits, hemorrhagic episodes, and bladder and/or bowel dysfunction, indicating increased disease severity. Resection was associated with significantly improved long-term functional outcomes (OR 3.27, 95% CI 1.72–6.24) compared with conservative management. There was no significant difference between the two groups regarding odds of long-term clinical deterioration (OR 1.03, 95% CI 0.35–3.03). However, the risk of hemorrhagic episodes during follow-up was higher in the conservative group (17.3%) compared with the surgical group (1.69%). The odds of hemorrhage during follow-up were lower in the surgical group, although not statistically significant (OR 0.24, 95% CI 0.05–1.05). CONCLUSIONS This study highlights that while surgical management of SCCMs is associated with better long-term functional outcomes and reduced risk of recurrent hemorrhage, treatment decisions must be carefully tailored to the individual patient, particularly given the potential risks associated with surgery. Conservative management, although less invasive, carries a nonnegligible risk of hemorrhage during follow-up, warranting close monitoring. These findings parallel management strategies used for brainstem cavernomas, for which surgery is reserved for cases with low surgical risk and worsening neurological symptoms. However, the limitations of current data, including selection bias and heterogeneity in reporting, emphasize the need for a multi-institutional registry to better define the natural history of SCCMs and inform future management strategies.

614 Background: Liver transplantation (LT) offers a 5-year survival exceeding 70% for selected patients with hepatocellular carcinoma (HCC). Immune checkpoint inhibitors (ICIs) may be used to downstage or bridge to transplantation. This study aims to evaluate the safety of ICIs prior to LT. Methods: Multicenter retrospective study, involving 9 centers, included adults who received ICIs and, subsequent LT, between 2019 and 2023. The ICI cohort was matched by age, sex, liver diseases and transplant date (1:3) with a similar cohort of HCC transplanted patients that did not receive ICIs. Results: The ICI cohort included 45 patients (Table part 1). The most common underlying liver diseases were viral. 15.5% of patients had macrovascular invasion and, 62.2% multifocal disease. The most commonly used ICI was nivolumab (75.6%), followed by atezolizumab-bevacizumab (17.8%). The median follow up was 32.5 months (17.4 - 47.6). The median ICI duration was 147 days (129.5-276.5), with a median interval of 58 days (22–193) between the last ICI dose and LT. There were 8 (17.8%) cases of graft rejection, 2 steroid-resistant leading to 1 graft failure. There were 4 (8%) HCC recurrences. During follow-up there were 6 deaths, 2 related to HCC recurrence and 4 non liver related. When compared with 135 non-ICI cohort patients, there were no differences within the groups (Table part 2). Importantly, we found no significant differences in crude rejection rates (p=0.5). Conclusions: Our study suggest that ICI treatment prior to LT is safe. ICI rejection primarily occurs in the acute post-transplant period (within 3 months), with a low risk of death due to graft failure. Further clinical trials are needed.

Importance Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology. Objective To examine the association between depressive symptoms and amyloid pathology and its dependency on age, sex, education, and APOE genotype in older individuals without dementia. Design, Setting, and Participants Cross-sectional analyses were performed using data from the Amyloid Biomarker Study data pooling initiative. Data from 49 research, population-based, and memory clinic studies were pooled and harmonized. The Amyloid Biomarker Study has been collecting data since 2012 and data collection is ongoing. At the time of analysis, 95 centers were included in the Amyloid Biomarker Study. The study included 9746 individuals with normal cognition (NC) and 3023 participants with mild cognitive impairment (MCI) aged between 34 and 100 years for whom data on amyloid biomarkers, presence of depressive symptoms, and age were available. Data were analyzed from December 2022 to February 2024. Main Outcomes and Measures Amyloid-β1-42 levels in cerebrospinal fluid or amyloid positron emission tomography scans were used to determine presence or absence of amyloid pathology. Presence of depressive symptoms was determined on the basis of validated depression rating scale scores, evidence of a current clinical diagnosis of depression, or self-reported depressive symptoms. Results In individuals with NC (mean [SD] age, 68.6 [8.9] years; 5664 [58.2%] female; 3002 [34.0%] APOE ε4 carriers; 937 [9.6%] had depressive symptoms; 2648 [27.2%] had amyloid pathology), the presence of depressive symptoms was not associated with amyloid pathology (odds ratio [OR], 1.13; 95% CI, 0.90-1.40; P = .29). In individuals with MCI (mean [SD] age, 70.2 [8.7] years; 1481 [49.0%] female; 1046 [44.8%] APOE ε4 carriers; 824 [27.3%] had depressive symptoms; 1668 [55.8%] had amyloid pathology), the presence of depressive symptoms was associated with a lower likelihood of amyloid pathology (OR, 0.73; 95% CI 0.61-0.89; P = .001). When considering subgroup effects, in individuals with NC, the presence of depressive symptoms was associated with a higher frequency of amyloid pathology in APOE ε4 noncarriers (mean difference, 5.0%; 95% CI 1.0-9.0; P = .02) but not in APOE ε4 carriers. This was not the case in individuals with MCI. Conclusions and Relevance Depressive symptoms were not consistently associated with a higher frequency of amyloid pathology in participants with NC and were associated with a lower likelihood of amyloid pathology in participants with MCI. These findings were not influenced by age, sex, or education level. Mechanisms other than amyloid accumulation may commonly underlie depressive symptoms in late life.

Introduction: Trust and rapport between patients and physicians form the cornerstone of effective medical practice. A key factor influencing this trust is the patient’s perception of the physician’s appearance. Women physicians often face more rigorous expectations concerning their physical appearance compared to men physicians, creating a need to balance traditional professional attire with maintaining femininity and individuality. This review explores the unique challenges women physicians encounter in presenting a professional image. Methods: A narrative review was conducted using PubMed and Google Scholar to identify studies addressing both patient and physician perceptions of physician appearance. The search was limited to studies conducted in the United States and published between 2004 and 2024. Seven articles met the inclusion criteria and were selected for analysis. Results: The findings suggest that professional attire, particularly when combined with a white coat, is associated with higher perceptions of competence and professionalism. However, women physicians face ambiguity in meeting these expectations compared with men. In addition, women are more frequently mistaken for nurses, phlebotomists, or support staff based on their attire and appearance. Discussion: Overall, patients tend to prefer professional attire to physicians, but these preferences are influenced by cultural, demographic, and age-related factors. Women physicians, in particular, experience heightened scrutiny regarding their appearance and are subject to stricter norms than men physicians. This challenge is further amplified for young women trainees, who may struggle to convey professionalism due to their youthful appearance.

ABSTRACT Introduction The COVID‐19 pandemic accelerated the shift from in‐person to virtual recruitment, prompting residency and fellowship programs to adopt innovative strategies, such as leveraging social media platforms to attract applicants and enhance visibility. Our aim was to identify and describe the presence of U.S. geriatric medicine fellowship programs on X. Methods We identified all U.S. geriatric medicine fellowship programs using FREIDA, and then located their X accounts through a stepwise process. Data were collected on account creation, number of followers, posts, and activity level, with an analysis of the last 100 posts from the most active accounts. Descriptive statistics were used to analyze the data. Results Among the 147 geriatric medicine fellowship programs identified, 38 (25.9%) had an X account. The majority of accounts were created after the start of the pandemic, reflecting likely the adaptation to virtual recruitment processes. Only a few accounts generated the majority of posts and followers. The accounts primarily posted or reposted educational content, research highlights, and promotional material. Conclusion The use of X by geriatric medicine programs is still significantly underutilized, with only one‐fourth of them having an account. Half of the accounts were created after the COVID‐19 pandemic began. Programs should focus on building a robust social media presence to increase their visibility, especially as virtual interviews have become a permanent part of recruitment.

OBJECTIVE To evaluate a regimen of inhaled Technosphere insulin (TI) plus insulin degludec in adults with type 1 diabetes, who prestudy were predominately using either an automated insulin delivery (AID) system or multiple daily insulin injections (MDI) with continuous glucose monitoring. RESEARCH DESIGN AND METHODS At 19 sites, adults with type 1 diabetes were randomly assigned to TI plus insulin degludec (N = 62) or usual care (UC) with continuation of prestudy insulin delivery method (N = 61) for 17 weeks. RESULTS Prestudy, AID was used by 48% and MDI by 45%. Mean ± SD HbA1c was 7.57% ± 0.97% at baseline and 7.62% ± 1.06% at 17 weeks in the TI group and 7.59% ± 0.80% and 7.54% ± 0.77%, respectively, in the UC group (adjusted difference 0.11%, 95% CI −0.10 to 0.33, P value for noninferiority = 0.01). HbA1c improved from baseline to 17 weeks by >0.5% (5.5 mmol/mol) in 12 (21%) in the TI group and in 3 (5%) in the UC group and worsened by >0.5% (5.5 mmol/mol) in 15 (26%) in the TI group and in 2 (3%) in the UC group. The most common TI side effect was a brief cough; eight participants discontinued TI due to side effects. CONCLUSIONS In adults with type 1 diabetes, HbA1c after 17 weeks with a regimen of TI and degludec was noninferior to UC, which consisted predominately of either AID or MDI. TI should be considered an option for people with type 1 diabetes, particularly those who are motivated to further reduce postprandial hyperglycemia.

Despite the high initial responses to chimeric antigen receptor T (CART) cell therapy, most patients relapse within the first 1-2 years. T cell quality influences the success of CART cell therapies greatly, and T cells from cancer patients are prone to transition into dysfunctional states, such as exhaustion or senescence. The role of exhaustion in CART cell failures has been studied extensively; however, the role of T cell senescence has remained mostly unexplored. In this study, we aimed to determine the development of CART cell senescence and its impact on CART therapeutic efficacy. First, we studied the development of CART cell senescence using an in vitro model to induce CART cell dysfunction. Here, we cyclically activated CD19-directed chimeric antigen receptor T (CART19) cells (either costimulated via 4-1BB (BBζ) or CD28 (28ζ)). Activation cycles are designed to mimic recurrent activation of CART cells to study the impact of T cell activation on CART cell fates throughout treatment. We added a rest time in between activation cycles to focus on senesced CART cell populations since, unlike exhaustion, senescence is irreversible even after rest. We examined CART immunophenotype, cell cycle regulators, transcriptomic profile, senescence marker gene expressions and T cell effector functions on days 0 (D0-T cell), 8 (D8-baseline CART), and 15 (D15-CART cell after one activation/rest cycles). Following an activation/rest cycle, T cell exhaustion markers CTLA4, LAG3, and PD1 returned to basal levels after an initial increase due to activation, while only TIM-3 levels remained elevated (BBζ: p=0.0090, 28ζ: p=0.0394). Increased TIM-3 expression is associated with T cell senescence, which prompted us to further investigate the development of a senescence phenotype. We found a prominent T cell senescence phenotype in BBζ compared to 28ζ, as evident by increased expression of p53 (BBζ: p=0.0248), p21 (BBζ: p=0.0483), CD27 (BBζ: p=0.0080), CD28 (BBζ: p=0.0327), uPAR (BBζ vs. 28ζ: p<0.0001), and KLRG1 (BBζ vs. 28ζ: p=0.0029) in recurrently activated-rested CART cells. Next, we evaluated the transcriptomic signature of recurrently activated-rested CART cells. Gene set enrichment analysis (GSEA) indicated enrichment of gene sets related to senescent T cells as well as senMayo, a novel gene set which is reported to be selectively enriched in senescing cells or tissues, in BBζ, but not in 28ζ, compared to T cell D0 or in BBζ D15 compared to 28ζ D15 (p=0.00014 and p=0.089, respectively). MYC-related gene sets were found to be significantly enriched in recurrently activated/rested BBζ and depleted in 28ζ (p<0.1). MYC expression is increased in BBζ (p= 0.0010) while decreased in 28ζ (p=0.0036) upon recurrent activation and is higher in BBζ (D8: p=0.0018, D15: p= 0.0022) compared to 28ζ at indicated time points by qPCR. Given these results, we induced senescence in CART cells using two alternative strategies: MYC-T58A activation (oncogene-induced senescence) and irradiation. Senescence induced by MYC-T58A overexpression ameliorated only BBζ killing (p=0.0057), whereas senescence induced by irradiation improved 28ζ killing (p= 0.0086), indicating versatile impact of senescence on treatment outcome diverse CART cell therapies. Finally, analysis with two independent patient data sets correlated the emergence of senescence with contradicting clinical outcomes to BBζ and 28ζ treatments. The presence of senescent 28ζ cells in the peripheral blood of 28ζ-treated patients was reported to be associated with complete response in the clinic in an independent analysis. In another cohort, 28ζ-treated patients with higher senescence score were correlated with longer disease-free survival (p=0.0029), while senMayo gene set enrichment in BBζ-treated patients was associated with non-response in the clinic (p=0.014). In the same cohort, MYC-related gene sets-the same genes sets enriched in our recurrently activated/rested BBζ-are also enriched in nonresponsive BBζ-treated patients. In summary, our study indicates that (i) CART cells are susceptible to a state of senescence, as demonstrated using three independent approaches (repeated activation/rest, irradiation, and MYC modulation), (ii) CART senescence is more prominent in BBζ than 28ζ, and (iii) senescence is associated with worse outcomes following BBζ but not 28ζ treatment.
