Background: Some studies have reported more severe chondral pathology and less successful hip arthroscopic outcomes in patients with acetabular subchondral cysts. Purpose/Hypothesis: The purpose of this study was to report multicenter arthroscopic outcomes of patients with and without acetabular bone cysts. It was hypothesized that patients with acetabular cysts would demonstrate inferior outcomes at minimum 2-year follow-up compared with patients without acetabular cysts. Study Design: Cohort study; Level of evidence, 3. Methods: A multicenter matched-pair study was performed across 6 medical centers with data from a large prospectively collected database. Inclusion criteria were adult patients who had undergone primary unilateral hip arthroscopy for femoroacetabular impingement syndrome (FAIS). The study group was defined by the presence of a superolateral acetabular subchondral cyst on preoperative imaging. A control group was matched on age; sex; body mass index (BMI); lateral center-edge angle (LCEA); alpha angle; arthroscopic treatments of femoroplasty, acetabuloplasty, and labral treatment (ie, repair, reconstruction, or debridement); Beck chondral grade; and minimum 2-year outcomes using visual analog scale (VAS) for pain, International Hip Outcome Tool-12 (iHOT-12), minimal clinically important difference (MCID), substantial clinical benefit (SCB), and Patient Acceptable Symptom State (PASS). Results: The study included 82 patients, of whom 41 composed the study group and 41 served as matched control patients. The study group had a mean age of 42.16 ± 11.26 years with 48.78% women and a mean BMI of 26.51 ± 4.31 kg/m 2 . Mean LCEA was 33.55°± 6.30°, and mean alpha angle was 70.22°± 9.71°. Mean Beck chondral grade was 2.59 ± 1.27 in the study group and 2.70 ± 0.95 in the matched control group ( P = .72). Two-year mean postoperative iHOT-12 scores for the study and control groups were 69.49 ± 24.51 and 73.24 ± 25.16, respectively ( P = .38), whereas mean postoperative VAS scores for pain were 18.84 ± 18.17 and 20.74 ± 21.39, respectively ( P = .70). The study group reached MCID in 82.93%, SCB in 58.54%, and PASS in 65.85% and were similar to those of the control group. Conclusion: Patients undergoing arthroscopic surgery for FAIS with acetabular cysts had similarly successful outcomes as patients without acetabular cysts. Acetabular subchondral cysts may not be a contraindication to hip arthroscopy in patients with FAIS who would otherwise be indicated for this surgery.

Abstract Chimeric antigen receptor (CAR) T-cell therapy enriched for a memory-like phenotype may persist and function longer than a nonenriched product, thereby improving duration of response (DOR). We conducted a phase I study with bb21217 (NCT03274219), an anti–B-cell maturation antigen CAR T-cell therapy manufactured in the presence of the phosphoinositide 3-kinase inhibitor bb007 to enrich for T cells with a memory-like phenotype, in patients with relapsed/refractory multiple myeloma (N = 72). No new safety concerns were raised with bb21217 therapy (three cases each of grade ≥3 cytokine release syndrome and grade ≥3 neurotoxicity were observed). The objective response rate was 69.4% and the median DOR was 23.8 (95% confidence interval, 16.8–34.8) months. Analysis of the drug product established an association between early memory phenotype and robust expansion and depth of response. Examination of baseline characteristics indicated that tumor burden and prior therapies influenced DOR. The data indicate that generation of CAR T cells early in a disease course when tumor burden is lower and source material exhibits a more naïve phenotype may maximize the clinical benefit potential of the drug product.

INTRODUCTION: Clostridioides difficile infection (CDI) presents a significant challenge in patients with inflammatory bowel disease (IBD), with high recurrence rates and complications. Predicting recurrent CDI (rCDI) in patients with IBD is crucial for implementing targeted interventions to improve patient outcomes. This study aimed to develop and validate a predictive model (RecurCDI-IBD) using supervised machine learning to identify patients with IBD at high risk of developing rCDI. METHODS: Data were collected from adult patients with IBD diagnosed with CDI between 2013 and 2021. Inclusion criteria included adult patients with a confirmed diagnosis of CDI and a history of IBD. The Gradient Boosting Machine learning model (XGBoost) was used to train a binary classification model. Feature engineering included demographic data (age and sex), clinical data (IBD subtype, medication use, and comorbidities), and laboratory data. The primary outcome was the occurrence of rCDI within 60 days of the initial CDI episode. RESULTS: The RecurCDI-IBD model achieved an accuracy of 80.05% and an Area Under the Curve of 0.88 for predicting rCDI. Key predictive features included IBD subtype, sex, specific medications (such as steroids and anti-TNF agents), and comorbidities (such as chronic pulmonary and renal disease). DISCUSSION: The RecurCDI-IBD model demonstrates good discriminatory ability with balanced precision and recall in identifying patients with IBD at higher risk for rCDI. These findings highlight the potential of data-driven approaches to support clinical risk assessment. Further studies incorporating larger and more diverse cohorts and prospective external validation are needed to confirm generalizability and optimize clinical applicability.

Abstract Objective This study aimed to evaluate how differences in case complexity affect information-processing burden, as measured by eye-tracking, as well as the efficiency of electronic health record (EHR) use among healthcare providers in the intensive care unit. Materials and Methods This cross-sectional study recruited providers from 4 U.S. medical centers that use 2 prominent EHR systems (Epic and Oracle). After reporting demographic information, participants reviewed 2 complex cases and 2 standard cases in their institution’s EHR system and then responded to 5 questions about each case, yielding a performance score. Information-processing burden was assessed by measuring the number of eye fixations via eye-tracking software. The efficiency of EHR use was assessed by measuring the task completion time, number of mouse clicks per minute, number of EHR screens viewed, and performance score. Results Eighty-one providers were included for analysis. Providers exhibited significantly more eye fixations (P < .001) and longer task completion times (P < .001) for complex cases than for standard cases. There were also significantly fewer mouse clicks per minute during complex cases (P < .001). Reviewing a complex case first led to significantly more eye fixations (P = .015) and longer task completion times (P < .01) than when a standard case was presented first. Case complexity did not significantly affect performance scores or the number of EHR screens viewed. Discussion Higher case complexity was shown to be associated with greater information-processing burden and less efficient EHR use. These findings have implications for enhancing the efficiency of EHR use, thereby leading to improved clinical decision-making and patient safety. Furthermore, reviewing complex cases first led to a greater information-processing burden, suggesting that providers could benefit from “warming up” with standard cases before reviewing complex cases.

ABSTRACT Objective This study compared the effects of phentermine‐topiramate‐ER (mid‐dose 7.5/46 mg) versus placebo on weight loss and cardiovascular disease (CVD) risk outcomes when used as an adjunct to a digitally enhanced lifestyle intervention (DELI). Methods We conducted a 12‐month, randomized, double‐blind, placebo‐controlled trial at a single tertiary academic center in the United States (June 2020–June 2022). Eighty participants with obesity (BMI ≥ 30 kg/m 2 ) were enrolled in the DELI program, consisting of in‐person and telehealth modalities, dietary and physical activity goals, and use of a smartphone application integrated with digital devices (Apple Watch and Bluetooth‐enabled weight scale and blood pressure monitor). Participants were randomized 1:1 to receive either phentermine‐topiramate‐ER ( n = 42) or placebo ( n = 38) in addition to the DELI. Results At 3 months, the phentermine‐topiramate group lost a mean of 10.82 kg versus 4.04 kg in the placebo group (mean difference −6.78 kg; p = 0.002). At 12 months, weight loss was 15.32 kg versus 5.85 kg, respectively (mean difference −9.48 kg; p < 0.001). Participants receiving phentermine‐topiramate‐ER experienced a 3.35% reduction in the estimated atherosclerotic CVD risk compared to baseline ( p = 0.004). Conclusions Phentermine‐topiramate‐ER, when combined with a DELI, produced significant and sustained weight loss and reduced CVD risk in adults with obesity.

Abstract Background Inflammatory bowel disease (IBD) is associated with increased risk of major adverse cardiovascular events (MACE), likely driven by systemic inflammation. Treating inflammation may reduce this risk. We aimed to investigate MACE across different therapies in patients with IBD. Methods We used Swedish nationwide registers (2007–2023) to describe MACE rates (ischemic heart disease, stroke, heart failure, and cardiovascular mortality) in patients with IBD receiving different therapies. For contextualization, we compared MACE rates during therapy exposure periods in patients with IBD with matched (by age, sex, and residence) general population comparators without IBD. Comparisons included exposure periods naïve to immunomodulators/advanced therapies and periods of different treatments (immunomodulators, TNF-α inhibitors (TNFi), vedolizumab, ustekinumab, and Janus kinase inhibitors). Each patient could contribute with multiple periods, with a new period starting upon switch of therapy. Incidence rates (IRs) and adjusted hazard ratios (aHRs) were estimated by using Cox regression (Model 1: conditioned on matching variables; Model 2: additional adjustment for Charlson Comorbidity Index). Among patients with IBD, we performed 1:1 propensity score (PS)-matched analysis, with exposure periods of TNFi or vedolizumab as the reference, to compare MACE rates between advanced therapies. In these comparisons, we adjusted for demographics, disease characteristics, healthcare utilization, prior treatment, and cardiovascular risk factors. Results We included 106,894 patients with IBD with 99,661 exposure periods naïve to immunomodulators/advanced therapy, 60,573 exposure periods of immunomodulators, and 71,551 of advanced therapies. Distribution of age, sex and disease duration differed substantially across therapy exposures (data not shown). Compared with the general population, MACE rates in patients with IBD were similar across therapies (IRs=3.0-13.0/1,000 person-years; aHRs=1.02-1.49) (Table 1), and significantly increased only for exposure periods naïve to immunomodulators/advanced therapy, immunomodulators, or ustekinumab. In PS-matched comparisons, no significant differences were found between periods of TNFi, vedolizumab and other advanced therapies (Table 2). Conclusion Therapy exposure periods in patients with IBD showed only slightly increased MACE rates compared to corresponding periods in the general population, and significantly so only for periods naïve to immunomodulators/advanced therapy and exposure to immunomodulators or ustekinumab. In PS-matched analyses of patients with IBD, no significant differences in MACE rates were observed when comparing exposure periods of different advanced therapies.

Abstract Background The cerebellar dentate is a known site of iron accumulation and tau deposition in progressive supranuclear palsy (PSP); however, detailed iron distribution and localized volume and shape changes remain unclear across PSP clinical variants. Objective The study aimed to clarify details about regional susceptibility distribution, volume, and shape deformation in the cerebellar dentate across PSP clinical variants. Methods Sixty‐seven PSP patients, including 31 PSP‐Richardson syndrome, 12 PSP‐parkinsonism, 10 PSP‐progressive gait freezing, and 14 PSP‐cortical variants (PSP‐frontal, PSP‐speech/language, and PSP‐corticobasal syndrome), and 31 healthy controls underwent 3 Tesla magnetic resonance imaging to reconstruct quantitative susceptibility maps. Manual dentate segmentation was performed to extract magnetic susceptibility and volume adjusted for total intracranial volume. Shape deformation was assessed using Deformetrica atlas construction. Group comparisons were evaluated with Kruskal–Wallis tests and receiver operating characteristic analysis. Results Patients with PSP‐Richardson syndrome, PSP‐parkinsonism, and PSP‐cortical variants showed significantly increased dentate susceptibility compared with controls ( P < 0.05). Patients with PSP‐progressive gait freezing showed no significant susceptibility differences. Volume loss was most prominent in PSP‐cortical variants, bilaterally, and PSP‐Richardson syndrome, left hemisphere only ( P < 0.05). Shape analysis revealed subregion‐specific deformation patterns, especially in the anterior and posterior deformation in PSP‐progressive gait freezing and the ventroanterior deformation in PSP‐cortical variants. Conclusions The PSP clinical variants had different patterns of susceptibility, volume, and shape metrics, reflecting distinct neurodegenerative patterns of the cerebellar dentate. These findings contribute to our understanding of the neurobiology of PSP and may help to improve phenotypic differentiation of PSP clinical variants. © 2026 International Parkinson and Movement Disorder Society.
