Abstract Apathy is a prevalent and persistent neuropsychiatric syndrome across many neurological disorders, significantly impacting both patients and caregivers. We systematically quantified discrepancies between self- and caregiver-reported apathy in 335 patients with a variety of diagnoses, such as frontotemporal dementia (behavioural variant and semantic dementia subtypes), Parkinson’s disease, Parkinson’s disease dementia, dementia with Lewy bodies, Alzheimer’s disease dementia, mild cognitive impairment, small vessel cerebrovascular disease, subjective cognitive decline and autoimmune encephalitis. Using the Apathy Motivation Index (AMI) and its analogous caregiver version (AMI-CG), we found that caregiver-reported apathy consistently exceeded self-reported levels across all conditions. Moreover, self-reported apathy accounted for only 14.1% of the variance in caregiver ratings. This apathy reporting discrepancy was most pronounced in conditions associated with impaired insight, such as behavioural variant frontotemporal dementia, and was significantly correlated with cognitive impairment. Deficits in memory and fluency explained an additional 11.2% of the variance in caregiver-reported apathy. Specifically, executive function deficits (e.g. indexed by fluency) and memory impairments may contribute to behavioural inertia or recall of it. These findings highlight the need to integrate patient and caregiver perspectives in apathy assessments, especially for conditions with prominent cognitive impairment. To improve diagnostic accuracy and deepen our understanding of apathy across neurological disorders, we highlight the need for adapted apathy assessment strategies that account for cognitive impairment particularly in individuals with insight or memory deficits. Understanding the cognitive mechanisms underpinning discordant apathy reporting in dementia might help inform targeted clinical interventions and reduce caregiver burden.

Black patients with metastatic prostate cancer have higher mortality rates compared to non-Hispanic White patients. There are no data on outcomes with [177Lu]Lu-PSMA-617 (LuPSMA) across racial groups. We evaluated the association between race and outcomes with LuPSMA in a multi-institutional cohort of consecutive patients with mCRPC treated with LuPSMA. The primary outcomes were PSA-50 rate, PSA-progression-free survival (PSA-PFS), and overall survival (OS). Statistical models were adjusted for age, number of prior therapies, sites of metastases, and baseline PSA. A total of 654 patients were included; 593 (91%) were White, 45 (7%) were Black and 16 (2%) were another non-Black minority (NBM). There were no statistically significant differences in PSA-50 rates, PSA-PFS and OS between the groups. Black and White patients treated with LuPSMA had similar clinical outcomes; efforts are needed to ensure Black and NBM patients have equal access to life prolonging therapies to narrow disparities in outcomes.

Background: Evaluate survival outcomes of PN compared to RN in patients with T1-2, N0, M0 cRCC. Methods: Patients with cRCC were identified using the National Cancer Database (NCDB). Inclusion criteria included T1-2, N0, M0 disease, treatment with either PN or RN, and a Charleston Deyo co-morbidity score of 0. Patients with missing survival data, advanced staging, or incomplete surgical information were excluded. Propensity score matching was performed to create identical groups with respect to age, sex, and race. Kaplan–Meier survival curves, multinomial logistic regression, and cox proportional hazard models were used for statistical analysis. Results: Of the 476 eligible propensity matched patients, 238 (50.0%) underwent PN and 238 (50.0%) underwent RN. PN was associated with better survival (mean: 186 vs. 170 months, P < 0.05) and lower odds of death (OR = 3.43; 95% CI, 2.05-5.76; P < 0.05). Five- and ten-year survival rates for PN were 95.2% and 91.1%, compared to 87.4% and 76.0% for RN. Patients treated with PN were significantly more likely to come from a higher income quartile and be treated at an academic/research facility. Conclusion: Partial nephrectomy demonstrates superior survival and shorter hospital stays compared to radical nephrectomy in localized cRCC, reinforcing its role as the preferred surgical approach.

Purpose: Part II of this consensus aimed to provide recommendations for the prevention of meniscus injuries, nonoperative treatment of acute tears and degenerative lesions, return to sports and patient-reported outcome measures. Methods: This consensus followed the European Society of Knee Surgery, Sports Traumatology and Arthroscopy (ESSKA) formal consensus methodology. For this combined ESSKA—American Orthopedic Society for Sports Medicine (AOSSM)—American Academy of Sports Physical Therapy (AASPT) initiative, 67 experts from 14 countries, including orthopedic surgeons and physiotherapists, were involved. The 26 Steering Group members established guiding questions, screened the existing evidence, and proposed statements, and provided Grades of recommendations. The 41 Rating Group members assessed the statements according to a Likert scale (1–9). Final documents were assessed by an international peer review group for geographical adaptability. Results: Low to moderate scientific level of evidence was available, so that grades of recommendations were low (3 Grade A ratings, 4 Grade B, 3 Grade C and 13 Grade D), underlining the relevance of this consensus. One strong and 17 relative agreements with overall median of 8 (8–9) and a mean of 7.92 ± 0.37 were achieved for 23 statements on 18 questions. Prevention of meniscus injuries is possible with general knee injury reduction programs and through avoidance of certain activities. Non-operative treatment including physical therapy is the first line approach for degenerative meniscus lesions and may be an option for some acute tears. Return to sports after meniscus tear surgery should be both criterion-based and timebased. Patient reported outcomes in combination with performance-based measures are recommended to evaluate the rehabilitation process. Conclusion: This international EU–US consensus established recommendations for prevention strategies, describes rehabilitation of nonoperated patients and of patients after partial meniscectomy, meniscus repair and meniscus reconstruction, and establishes return to sport criteria. These updated and structured recommendations may be applied by surgeons and physiotherapists. Level of Evidence: Level I, consensus.

ABSTRACT Background Transvenous lead removal (TLR) is a Class I indication for patients with cardiac implantable electronic device (CIED) infections. However, disparities in the utilization of TLR have not been fully explored, particularly concerning demographic and socioeconomic factors. Objectives This study aims to examine whether disparities exist among patients hospitalized for CIED infections with respect to the utilization of TLR, focusing on sex, race, and income characteristics. Methods We utilized the 2019 National Inpatient Sample (NIS) to assess patients hospitalized with CIED infections and identify those who underwent TLR. Multiple logistic regression was used to examine risk factors for TLR utilization, including age, sex, race/ethnicity, and socioeconomic characteristics. Results A total of 56 709 patients were hospitalized for CIED infection in the United States in 2019, of which 9867 (17.4%) underwent TLR. On an adjusted analysis, females and Black patients were found to have lower odds of undergoing TLR compared to males and White patients (OR: 0.62; 95% CI: 0.59–0.78; p < 0.01; and OR: 0.47; 95% CI: 0.39–0.57; p < 0.01, respectively). Hispanic patients also had reduced odds of TLR (OR: 0.73; 95% CI: 0.58–0.93; p = 0.01). No significant associations were observed between income or insurance status and the likelihood of receiving TLR after adjustment. Conclusions This study identified significant disparities in the utilization of TLR among patients hospitalized for CIED infections. Female, Black, and Hispanic patients were significantly less likely to receive TLR.

Abstract Measles virus (MeV) is a highly contagious pathogen capable of infecting immune cells and thereby causing immunosuppression and immune amnesia. A live-attenuated MeV vaccine is highly efficacious and has been safely administered for over 60 years. However, a detailed mechanistic understanding of the mode of its attenuation remains elusive. Here, we determined the molecular mechanisms underlying MeV vaccine attenuation in primary human immune cells. Enhanced infection of innate immune cells resulting in uncontrolled viral RNA synthesis and reduced ability to evade host antiviral responses induced a strong type-I interferon signature that arrested replication of the vaccine strain. In contrast, the wild type virus replicated slowly but steadily, avoiding detection by innate immunity.

Abstract Full waveform inversion (FWI) is one of the advanced inversion-based ultrasound computed tomography (USCT) techniques that can identify the material properties and produce high-resolution inverted images of the specimen, making it promising for applications in nondestructive evaluation (NDE) and structural health monitoring (SHM). However, this process is computationally expensive and time-consuming due to its ill-posed nature and inherent nonlinearity. To mitigate these challenges and enhance the efficiency of FWI, this study explores an alternative approach using artificial intelligence (AI) as a data-driven regularization. However, one of the major challenges in such a data-driven approach is the inadequate amount of data to train the neural network. To address this bottleneck, 2D numerically generated samples are used to train the neural network in this study. In addition, two different source time functions (STF) were used for FWI simulations to understand the effect of using different waveforms on the deep-learning (DL) based solution. The first STF was numerically generated and the second was acquired by inverting experimental data using a multi-channel data acquisition system from the Verasonics. For evaluation, the structural similarity index measure (SSIM) and peak-signal noise ratio (PSNR) metrics are used to compare the predicted images with the ground truth images. The results demonstrate the efficacy of the DL-based approach, with improvements of 22.5% and 78% in SSIM and 47% and 73% in PSNR over the classical FWI simulations for the first and second STFs, respectively. The DL-based adjoint tomography architecture for USCT presented in this work has a strong potential for material characterization and detecting internal defects and variations.
