Abstract Objectives The impact of mild autonomous cortisol secretion (MACS) on cognition is incompletely characterized. We aimed to assess cognition in patients with MACS, identify factors associated with lower cognition, and determine the impact of adrenalectomy on cognition. Methods We conducted a cross-sectional study (4/2019 to 10/2022) and a longitudinal cohort study (10/2021 to 9/2023) of adults with MACS and referent subjects. Cognition was assessed with National Institute of Health Toolbox Cognition Battery and reported as standardized T scores (adjusted for age, sex, race/ethnicity, and education) for fluid, crystallized, and total composite cognition. Participants were assessed with urine steroid profiling (liquid chromatography-tandem mass spectrometry), frailty index, Beck’s Depression Inventory (BDI), and Short Form-36 (SF-36). Results A total of 84 patients (median age 57 years, 67% women) and 201 referent subjects (median age 63 years, 58% women) were included. Patients with MACS demonstrated lower mean (SD) total composite (50.9 [9.3] vs 55.4 [8.9], P < .001) and fluid composite T score (49.3 [10.6] vs 55.2 [10.2], P < .001), but not crystallized composite T score (52.3 [8.4] vs 54.0 [8.4], P = .130) when compared with referent subjects. Multivariable analysis adjusted for age, sex, BDI, SF-36, frailty index, total glucocorticoids, and androgens demonstrated that MACS status was associated with lower cognition. When cognition was reassessed in 37 patients post-adrenalectomy and 31 referent subjects, adjusted group differences of cognition change were similar except for a higher comparative increase in attention and executive functioning in patients with MACS. Conclusion Patients with MACS demonstrate lower cognition than referent subjects. Adrenalectomy for MACS had a minor positive impact on cognition.

OBJECTIVE The floor of the third ventricle and the interpeduncular and prepontine regions represent challenging surgical targets. The expanded endoscopic endonasal approach (EEA) with pituitary gland (PG) transposition has been proposed to provide direct access to these anatomical regions. Through the years, different endoscopic PG transposition techniques have been studied and presented. The goal of this study was to compare the techniques, relevant anatomy, and surgical exposure of extradural, intradural, and interdural PG transposition techniques. METHODS Six formalin-fixed, latex-injected cadaveric head specimens were used to perform the EEA with extradural, unilateral interdural, and unilateral intradural PG transpositions. The interpeduncular and prepontine regions and the neurovascular structures located within these cisterns were carefully exposed and analyzed. The maximal cranial, caudal, and lateral accessible points within the surgical field were identified for each approach. Consequently, the relative craniocaudal and horizontal surgical axes were measured to quantify the extent of accessibility of each approach. RESULTS The extradural PG transposition technique provided the largest horizontal extensions and bilateral access to structures within the interpeduncular and prepontine regions; the mean horizontal axis was 17.9 (range 13.9–20.4) mm. The unilateral interdural PG transposition provided wider vertical exposure, with a mean craniocaudal axis of 16.2 (range 13.0–20.9) mm. In this approach, the surgical field was extended cranially above the ipsilateral mammillary body (MB). The unilateral intradural PG transposition provided a similar surgical exposure to the interdural approach, with a mean craniocaudal axis of 14.7 (range 12.9–15.8) mm. The approach required significant manipulation of the PG after opening both periosteal and meningeal dura layers. CONCLUSIONS The extradural PG transposition is indicated for lesions of the upper clivus region that extend bilaterally and do not have a cranial extension beyond the MBs. The inter- and intradural PG transpositions are beneficial for unilateral lesions that extend cranially to the MBs. Both techniques require coagulation of the ipsilateral inferior hypophyseal artery. The intradural technique requires more manipulation of the PG, while the interdural technique requires opening and access to the cavernous sinus. If needed, the intra- and interdural techniques can also be performed bilaterally.

Abstract Background Etrasimod is an oral, once daily (QD), selective sphingosine 1-phosphate1,4,5 receptor modulator for the treatment of moderately to severely active ulcerative colitis (UC). We assessed the benefit of etrasimod monotherapy and the impact of concomitant corticosteroids (CS) and/or 5-aminosalicylates (5-ASA) therapy. Methods In ELEVATE UC 52 and ELEVATE UC 12, patients with moderately to severely active UC were randomized 2:1 to etrasimod 2 mg QD or placebo for 52 and 12 weeks, respectively. Oral CS or 5-ASA were allowed at baseline. Patients in the monotherapy subgroup received etrasimod or placebo without concomitant CS and/or 5-ASA at baseline. Predefined primary (clinical remission) and key secondary efficacy endpoints aligned with those from both trials and were assessed at Week 12 and Week 52. Safety was assessed up to Week 52. Results Clinical remission rates at Weeks 12 and 52 were significantly higher for etrasimod compared with placebo in patients receiving monotherapy (Week 12: 26.2% vs 4.8%; Week 52: 35.7% vs 4.0%). Differences vs placebo were statistically significant for all predefined endpoints at both time points in patients receiving monotherapy or etrasimod with concomitant 5-ASA only (all P < .05); numerical differences, due to small sample sizes, vs placebo were observed for all endpoints in the CS only and CS + 5-ASA subgroups. Safety was consistent with the overall population. Conclusions Etrasimod monotherapy showed consistent efficacy and safety vs placebo; no apparent benefit was observed with concomitant CS and/or 5-ASA in patients receiving etrasimod. Clinical trial registration NCT03945188; NCT03996369.

Background: Diagnostic uncertainty caused by the low positive predictive value of HEV-specific IgM antibody (Ab) testing in a low-prevalence setting. We investigated the utility of a two-step HEV IgM Ab testing approach for diagnosing HEV infection. Methods: We retrospectively reviewed all adults who underwent HEV IgM Ab and/or HEV RNA testing from July 2013 through June 2023 at Mayo Clinic. Two-step HEV IgM testing involved initial testing using recomWell HEV IgM ELISA (Mikrogen, Neuried, Germany), with reflex to recomLine HEV IgM Strip (Mikrogen, Neuried, Germany) on all recomWell HEV IgM-reactive or IgM-equivocal specimens, as recomLine HEV IgM has higher specificity than recomWell HEV IgM but is more labor-intensive. Results: A total of 1640 patients had HEV IgM Ab or HEV RNA testing, including 1293 (79%) with only HEV IgM Ab testing, 213 (13%) with only HEV RNA testing, and 134 (8%) with both HEV IgM Ab and HEV RNA testing. Eighteen HEV infections were diagnosed with acute (N=16) and chronic (N=2) infections. Two-step IgM Ab testing did not identify 2 solid organ transplant recipients with chronic HEV infection. In acute HEV infection with HEV viremia, 3 out of 4 patients (2 solid organ transplant recipients and 1 patient with Guillain-Barre syndrome) were treated with ribavirin. Conclusions: A two-step HEV IgM Ab test may accurately diagnose acute HEV infection in immunocompetent persons. However, this approach fails to identify chronic HEV infection in immunocompromised individuals who need HEV RNA testing to establish the diagnosis.

PURPOSE SWOG S1815 was a randomized, open label phase III trial, evaluating gemcitabine, nab-paclitaxel, and cisplatin (GAP) versus gemcitabine and cisplatin (GC) in patients with newly diagnosed advanced biliary tract cancers (BTCs). METHODS Patients with newly diagnosed locally advanced unresectable or metastatic BTC, including intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (ECC) and gallbladder carcinoma (GBC), were randomly assigned 2:1 to either GAP (gemcitabine 800 mg/m 2 , cisplatin 25 mg/m 2 , and nab-paclitaxel 100 mg/m 2 intravenously once per day on days 1 and 8 of a 21-day cycle) or GC (gemcitabine 1,000 mg/m 2 and cisplatin 25 mg/m 2 intravenously once per day on days 1 and 8 of a 21-day cycle). RESULTS Among 452 randomly assigned participants, 441 were eligible and analyzable, 67% with ICC, 16% with GBC, and 17% with ECC. There was no significant difference in overall survival (OS) between GAP versus GC. Median OS with GAP was 14.0 months (95% CI, 12.4 to 16.1) and 13.6 months with GC (95% CI, 9.7 to 16.6); hazard ratio (HR), 0.91 (95% CI, 0.72 to 1.14); P = .41. Median progression-free survival (PFS) was similar between groups with median PFS for GAP being 7.5 months (95% CI, 6.4 to 8.5) versus 6.3 months for GC (95% CI, 4.4 to 8.2); HR, 0.89 (95% CI, 0.71 to 1.12); P = .32. In exploratory subset analyses, the OS and PFS benefits of GAP versus GC treatment were greater in locally advanced disease compared with metastatic disease, although not statistically significant (interaction P = .14 for OS and P = .17 for PFS). Moreover, GAP versus GC showed greater improvement in PFS among participants with GBC than those with ICC or ECC (interaction P = .01), but not OS (interaction P = .28). CONCLUSION The addition of a taxane in the GAP regimen to the standard gemcitabine-cisplatin regimen did not improve OS in newly diagnosed BTC. More toxicity was encountered with GAP versus GC.

ABSTRACT Patients with newly diagnosed acute myeloid leukemia (ND‐AML) derive variable survival benefit from venetoclax + hypomethylating agent (Ven‐HMA) therapy. The primary objective in the current study was to develop genetic risk models that are predictive of survival and are applicable at the time of diagnosis and after establishing treatment response. Among 400 ND‐AML patients treated with Ven‐HMA at the Mayo Clinic, 247 (62%) achieved complete remission with (CR) or without (CRi) count recovery. Multivariable analysis–derived hazard ratios (HR), including 1.8 for European LeukemiaNet (ELN) adverse karyotype, 4.7 for KMT2Ar , 1.7 for TP53 MUT , 2.6 for KRAS MUT , and 2.1 for IDH2 WT were applied to develop an HR‐weighted risk model: low, intermediate, and high; respective median survival censored for allogeneic stem cell transplant (ASCT) (3‐year survival) were “not reached” (67%), 19.1 (33%), and 7.1 months (0%). In patients achieving CR/CRi, adverse karyotype, KMT2Ar , KRAS MUT , IDH2 WT predicted inferior survival, allowing for a complementary response‐stratified risk model. The model was externally validated and was shown to be superior to the ELN 2024 risk model (AIC 179 vs. 195 and AUC 0.77 vs. 0.69). Survival was inferior with failure to achieve CR/CRi or not receiving ASCT; 3‐year survival for high‐risk with or without ASCT was 42% versus 0% ( p < 0.01); intermediate 72% versus 43% ( p = 0.06); and low‐risk 88% versus 78% ( p = 0.53). The Mayo genetic risk models offer pre‐treatment and response‐based prognostic tools for ND‐AML treated with Ven‐HMA. The current study underscores the prognostically indispensable role of achieving CR/CRi and ASCT.
