Abstract Context The impact of active hypercortisolism on sleep is incompletely characterized. Studies report impaired sleep in patients with Cushing syndrome (CS). Patients with mild autonomous cortisol secretion (MACS) demonstrate mild nocturnal hypercortisolism that could impact sleep. Objectives To characterize sleep abnormalities in patients with CS and MACS using the Pittsburgh Sleep Quality Index (PSQI), identify factors associated with poor sleep, and compare sleep abnormalities in patients with MACS vs referent subjects. Methods We conducted a single-center cross-sectional study of adults with active CS and MACS. Clinical and biochemical severity scores for hypercortisolism were calculated. Parallelly, we enrolled referent subjects. Quality of life was assessed using (1) the Short Form-36 (SF-36) in all participants and (2) the CushingQoL in patients with active hypercortisolism. Sleep quality was assessed using PSQI. Results PSQI was assessed in 154 patients with CS (mean 12, SD ±4.5), 194 patients with MACS (mean 11, SD 4.6), and 89 referents (mean 5, SD ±3.4). Patients with MACS exhibited shorter sleep duration, longer sleep latency, more severe daytime dysfunction, lower sleep efficiency, and a higher sleep medication use compared to referent subjects (P = <.001 for all). Age-, sex, and body mass index-adjusted analysis demonstrated no differences in PSQI or its subcomponents between patients with CS and MACS (P > .05 for all). In a multivariable analysis of patients with MACS, younger age, female sex, and higher clinical hypercortisolism severity score were associated with impaired sleep. In patients with CS, only younger age was associated with poor sleep. Conclusion Patients with MACS demonstrate sleep impairment that is similar to patients with CS. Younger women with higher clinical severity of MACS are more likely to have impaired sleep.

Importance The definition of cure in stage II to III colon cancer (CC) remains unclear due to limitations in conventional end points, which include deaths and second primary tumors as events. These can complicate communication with patients regarding long-term outcomes. Objective To distinguish relapses from competing health-related events to classify long-term outcomes years after surgery and explore when the incidence of true relapses of the initial CC approaches 0% to define cure in this disease. Design, Setting, and Participants This pooled analysis of individual patient–level data from 15 phase 3 randomized clinical trials assessed time to CC-related relapse using Kaplan-Meier and Aalen-Johansen methods, with death and second primary tumors treated as competing risks. Cox regression models evaluated prognostic associations, stratified by sex, stage, and tumor. Patients with stage II to III CC who underwent adjuvant chemotherapy were included. All patients had undergone radical surgery for CC and received adjuvant chemotherapy with a median follow-up of at least 6 years. The Adjuvant Colon Cancer Endpoints (ACCENT) and the International Duration Evaluation of Adjuvant Chemotherapy (IDEA) databases included adjuvant studies conducted between 1996 and 2015. Data were analyzed from February 2022 to June 2025. Exposures Adjuvant chemotherapy regimens varied across trials, including fluoropyrimidines alone or in combination with oxaliplatin or biologic agents. Main Outcomes and Measures The primary outcome was time to CC-related recurrence. The predefined threshold for cure was a recurrence risk below 0.5%. Results Of 35 213 included patients, 19 346 (54.9%) were male, and the mean (SD) age was 60.2 (10.8) years. The incidence rate of recurrence peaked at 6.4% (1993 of 31 373) between month 6 and month 12 and decreased continuously until year 10 of follow-up never exceeding 0.5%. Recurrence rate appeared to increase again after year 10 and peaked at 2.0% during year 12.5 to year 13, a pattern observed exclusively in the MOSAIC trial. Competing-event analysis revealed that death and second primary tumors inflated the apparent recurrence rate, especially for older patients. The overall cumulative incidence of relapse with death as competing risk was lower among female patients (hazard ratio, 0.58; 95% CI, 0.45-0.76; P < .001). Conclusions and Relevance In this pooled analysis of phase 3 randomized clinical trials, a recurrence rate less than 0.5% occurred after 6 years from surgery, supporting a practical definition of cure. Recognizing this milestone may improve patient communication, guide follow-up duration, and reduce unnecessary long-term surveillance.

Abstract Background Thyroid function testing is a common laboratory service that can be optimized by implementing evidence-based algorithms. The thyroid function cascade testing approach at Mayo Clinic Labs is utilized to effectively evaluate and monitor functional thyroid status. The cascade begins with thyroid-stimulating hormone (TSH) as a screening marker. When TSH levels are normal, no additional testing is necessary. When the TSH result is abnormal, appropriate follow-up free T4, total T3, and/or TPO testing will automatically be performed. Providers at our institution can order thyroid function testing with this cascade testing approach or as standalone individual orderable tests. Initial data analysis showed patterns of TSH ordered concurrently with free T4, total T3, and/or anti-TPO. Further analysis revealed that a high number of concurrently ordered tests would not have been necessary had the algorithmic approach been followed. This opportunity for improvement led to the thyroid function testing initiative to direct providers to order the cascade test rather than individual thyroid tests, thereby reducing concurrent and unnecessary testing to improve patient care. Methods The initiative involved creating a new Epic order panel directing providers to order the cascade rather than the individual orderable tests. This intervention is a soft stop that allows providers to proceed by ordering individual tests if desired. We evaluated the impact of the initiative on test utilization, cost savings, and quality indicators using pre- and post-intervention data from all Mayo Clinic sites over a 9-month period. We compared the monthly volumes of concurrent and unnecessary orders of Free T4, Total T3, and TPO before and after the intervention. Concurrent orders were defined as tests collected from the same patient on the same date and time as TSH tests. Unnecessary orders were defined as tests that were outside the reflex range according to the thyroid function ordering algorithm. Cost savings were calculated based on the 2024 CMS reimbursement rates for the associated test CPT® codes. We also monitored and addressed feedback and requests from providers and laboratory staff throughout the initiative. Results The intervention resulted in a 20% average monthly reduction in concurrent orders and an 18% average monthly reduction in unnecessary orders of free T4, total T3, and anti-TPO tests. Estimated savings based on 2024 CMS reimbursement rates are $5,000 monthly and nearly $60,000 annually. Thyroid testing quality was also improved by aligning with clinical guidelines, reducing over-testing, and minimizing the risk of misdiagnosis. Conclusion The thyroid function testing initiative was a successful laboratory stewardship project that reduced redundant testing, improved patient care, and reduced costs. The initiative demonstrated the feasibility and effectiveness of using evidence-based reflex algorithms to optimize laboratory testing. The lessons learned include assessing all tests related to the disease condition to mitigate potential unintended increases in test usage and accounting for patient groups that are not covered by the intended algorithm*s target population. Future directions include expanding the cascade approach to other areas of laboratory medicine, evaluating the long-term outcomes of the initiative, and engaging with providers to ensure the adoption of the initiative.

Background: Substance use disorders (SUDs) are highly prevalent, affecting over 48.5 million Americans. Available treatments for SUD remain insufficient, and many patients do not respond to existing interventions despite adequate adherence to treatments. While novel therapies for SUD are urgently needed, the use of psychedelic drugs for the treatment of SUDs has shown promise. Objectives: This overview of systematic reviews summarizes existing evidence on hallucinogens—serotonergic psychedelics and ketamine—for the treatment of SUD. Methods: A comprehensive search of the literature was conducted to identify relevant evidence for using serotonergic and non-serotonergic psychedelics for the treatment of SUDs. After initial screening (n = 468 studies), 62 studies were retrieved and assessed for eligibility, and a total of 16 systematic reviews were included. Conclusions: Although preliminary, evidence suggests that the use of serotonergic and non-serotonergic psychedelics for the treatment of SUD may provide advantages over traditional therapeutics, and these compounds may eventually become part of the next generation of treatments for SUD under specific circumstances. Research with these drugs has faced significant challenges, though, and caution when interpreting results is warranted, given high risk of bias and several other methodological limitations from the studies to date. Furthermore, risks associated with these drugs are not negligible. For now, the use of psychedelic drugs for the treatment of SUDs remains experimental, and existing evidence is insufficient to support its use in clinical practice.

ABSTRACT Background and Aims Clinically significant portal hypertension (CSPH; hepatic venous pressure gradient (HVPG) ≥ 10 mmHg) is a severe complication of chronic liver disease, with increased risk of variceal bleeding and liver decompensation (at HVPG ≥ 12 mmHg). This study evaluated the performance of multiparametric (mp)MRI for diagnosing CSPH and predicting liver decompensation, compared to ultrasound‐based shear wave elastography (SWE) and blood tests. Methods In this prospective single‐centre study (2018–2022), 59 patients (M 30, mean age 52.7 years) underwent mpMRI and HVPG measurement, with an average interval of 32 ± 31 days. The mpMRI protocol included 2D/3D MR elastography (MRE), T 1 /proprietary iron‐compensated T 1 (cT 1 )/T 1ρ mapping, gadoxetate‐enhanced dynamic contrast‐enhanced MRI (DCE‐MRI) of the liver and spleen, SWE and blood tests. Statistical analyses included Mann–Whitney U tests, ROC analysis, logistic regression and Cox proportional hazards models. Results CSPH was present in 13 patients (22%). Several MRI parameters showed high diagnostic performance for CSPH (AUC ≥ 0.8), with spleen stiffness‐2D MRE (AUC 0.88, 95% confidence interval (CI) 0.78–0.98) and liver uptake on DCE‐MRI (AUC 0.83, 95% CI 0.70–0.96) performing best, while SWE had AUCs of 0.63 (95% CI 0.45–0.81) for liver and 0.67 (95% CI 0.44–0.89) for spleen. Combining spleen stiffness‐2D MRE and liver uptake achieved an AUC of 0.93 (95% CI 0.86–1.00) for diagnosing CSPH. For predicting decompensation, spleen stiffness‐3D MRE and liver uptake rate had AUCs of 0.83 (95% CI 0.68–0.99) and 0.83 (95% CI 0.70–0.95), respectively, outperforming SWE. Conclusions Spleen stiffness measured with MRE combined with gadoxetate liver uptake (measured with DCE‐MRI) can diagnose CSPH and predict liver decompensation, with superior performance compared to SWE.

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.

A three year old male neutered mixed breed dog presented with a mass on the right carpus and accompanying lameness. A Jamshidi bone biopsy was performed, and histopathology results were consistent with a sarcoma. The dog received oncolytic virotherapy (OV) with vesicular stomatitis virus (VSV) as part of a clinical trial in dogs with osteosarcoma (OSA). Ten days after VSV treatment, the affected limb was amputated, and histopathology was consistent with intramedullary HSA. Considering the new diagnosis, standard doxorubicin chemotherapy was prescribed. With this combination of therapies, the dog had an extended survival of more than seven years and remains alive at the time of writing. This is the first case report documenting OV given in conjunction with the standard of care for canine appendicular HSA.

Abstract Objectives Hepatic steatosis impacts the quality of grafts, affecting transplant outcomes. Rising obesity rates and subsequent donor graft steatosis further influence the organ shortage crisis in pediatric liver transplantation (LT). Our study aimed to evaluate how donor steatosis modulates the outcomes of pediatric LT. Methods We analyzed the United Network of Organ Sharing database for transplanted donor grafts from January 01, 2004, to April 30, 2024. We stratified pediatric (≤18 years) LT recipients into steatotic grafts, subdivided into <30% and ≥30%. Graft failure was assessed using Kaplan–Meier curves, and Cox proportional hazards models, with Lasso regression identifying key predictive variables. Gradient‐boosting decision tree was used to assess the level of likelihood importance for post‐LT survival. Results Five hundred and ninety‐five pediatric LT recipients were included; 62 (10.4%) received donors with steatosis levels ≥30%. Survival rates for steatotic grafts ≥30% were 93.5% at 1 year, 89.9% at 5 years, and 84.4% at 10 years, compared to 94.7%, 89.5%, and 85.2% respectively, among steatotic grafts <30% ( p = 0.72, p = 0.92, and p = 0.92). Donor age (adjusted hazard ratio [aHR]: 1.01, 95% confidence interval [CI]: 1.01–1.03), donation after cardiac death (DCD) (aHR: 10.68, 95% CI: 3.27–34.86), and recipient life support (aHR: 1.95, 95% CI: 1.19–3.20) were associated with an increased risk of mortality. Conclusion Steatotic grafts in pediatric patients had acceptable outcomes. Predictors of mortality in steatotic grafts, including donor age, DCD, and recipient life support, underscore the complex interplay of multiple factors in post‐LT outcomes.

Background: There is a lack of data regarding the current state of lactation accommodations at continuing medical education (CME) events to guide best practice recommendations. Objective: To evaluate CME attendee attitudes, experiences, and preferences as it pertains to lactation support accommodations at CME events. Design: A cross-sectional study utilizing an electronic-based survey. Methods: Surveys were administered electronically to attendees of seven CME courses from August 2022 to October 2023, and de-identified data were collected to a secure database. Attitudes regarding lactation accommodations, personal preferences for lactation accommodations, and experiences with lactation at CME events were analyzed. Results: Of the 337 survey respondents, 169 had personal experience with lactation and 47 had experience with lactation at a CME course within the past 10 years. The majority of respondents agreed that lactation accommodations should be a priority ( n = 264, 83%) and are a medical need ( n = 285, 89%). Of those with recent experience lactating at a CME course, only 19% ( n = 9) indicated adequate lactation accommodations were provided. Due to inadequate accommodations, 77% ( n = 36) of respondents experienced decreased participation in the CME course content, 70% ( n = 33) claimed fewer hours of CME credit, and 74% ( n = 35) experienced decreased satisfaction in the CME course. Preferences for lactation accommodations included proximity to the meeting, audio–visual streaming of content, privacy, security, and signage supporting lactation in addition to an adequate designated space with access to an electrical plug and water supply. Conclusions: The current state of lactation accommodations at CME courses is inadequate and contributes to inequitable experiences for lactating participants. Course participants are supportive of lactating healthcare professionals at CME courses and recognize lactation accommodations as a priority. Further work is needed to inform and institute changes to lactation accommodations for healthcare professionals.
