SummaryThe goal of this study was to ascertain the effect of patient body size on clinic‐ or patient‐delayed health care during the COVID‐19 pandemic and factors predicting delay. Primary survey data were collected in August 2021 from 3593 individuals living within the communities near Mayo Clinic facilities in Minnesota, Wisconsin, Arizona, and Florida. More people who identified with the higher‐weight BMI categories reported having their care appointments cancelled (62.3%) compared to those who identified with normative weight (38.0%) or underweight (47.7%; p < .001) and reported more frequently delaying their own care (67.9%) relative to those who identified with normative weight (47.0%) or underweight (62.3%; p < .001). Higher‐weight people were more likely than others to report delay was due to not knowing where to get care (UW: 5.6%, NW: 3.5%, HW: 7.0%, pchi‐square < .001), worrying about weight‐based judgement (UW: 2.1%, NW: 2.1%, HW: 4.5%, pchi‐square < .001), and fearing discrimination (UW: 2.9%, NW: 2.4%, HW: 5.5%, pchi‐square < .001). There was no difference across groups in delay due to fear of COVID‐19 exposure. Weight gain was associated with care delay in higher‐weight and normative weight groups. Having experienced more patient‐centred care pre‐COVID was associated with less care delay in the normative weight group, but more care delay in other groups. Higher‐weight people were more likely to have their care delayed by health care providers and to delay care themselves. Patient weight gain and concerns about discrimination and judgement about weight gain may have driven the delay of needed care during COVID‐19.

ABSTRACTBackgroundLate gadolinium enhancement (LGE) on cardiovascular magnetic resonance (CMR) imaging is a well‐established indicator of myocardial fibrosis in hypertrophic cardiomyopathy (HCM). However, its association with electrocardiographic (ECG) abnormalities and the risk of atrial fibrillation (AF) remains uncertain.ObjectivesTo investigate the association between the presence and burden of LGE with ECG characteristics, including precordial voltage, depolarization and repolarization abnormalities, and the incidence of AF in adults with HCM.MethodsWe conducted a retrospective cohort study of 144 adults with HCM with CMR and 12‐lead ECG within 30 days of each other. LGE was quantified as a percentage of LV mass and categorized as absent, < 5%, or ≥ 5%. ECG parameters, including QRS voltage, repolarization abnormalities, and LVH criteria, were analyzed. Incident AF was assessed during a median follow‐up of 6.6 years.ResultsLGE was present in 96 (67%) patients, with 21 (22%) having ≥ 5% LGE. There were no significant differences in precordial voltage between patients with and without LGE across Sokolow‐Lyon, Cornell, and Romhilt‐Estes criteria. However, T‐wave inversion was more common in leads I (41% vs. 19%, p = 0.009), aVL (50% vs. 31%, p = 0.033), and V4 (41% vs. 23%, p = 0.035) in patients with LGE. Patients with ≥ 5% LGE had a significantly lower median LVEF (64% vs. 74%, p = 0.003). Additionally, LGE presence was not associated with an increased risk of incident AF (HR 1.8, 95% CI 0.6–5.3, p = 0.308).ConclusionIn contrast to pediatric HCM, LGE is associated with specific ECG repolarization abnormalities, particularly T‐wave inversion in lateral leads, but does not significantly affect precordial voltage in adults.

Abstract Purpose Lattice radiation therapy (LRT) is a form of spatially fractionated radiation therapy that allows increased total dose delivery aiming for improved treatment response without an increase in toxicities, commonly utilized for palliation of bulky tumors. The LRT treatment planning process is complex, while eligible patients often have an urgent need for expedited treatment start. In this study, we aimed to develop a simulation‐free workflow for volumetric modulated arc therapy (VMAT)‐based LRT planning via deep learning‐predicted synthetic CT (sCT) to expedite treatment initiation. Methods Two deep learning models were initially trained using 3D U‐Net architecture to generate sCT from diagnostic CTs (dCT) of the thoracic and abdomen regions using a training dataset of 50 patients. The models were then tested on an independent dataset of 15 patients using image similarity analysis assessing mean absolute error (MAE) and structural similarity index measure (SSIM) as metrics. VMAT‐based LRT plans were generated based on sCT and recalculated on the planning CT (pCT) for dosimetric accuracy comparison. Differences in dose volume histogram (DVH) metrics between pCT and sCT plans were assessed using the Wilcoxon signed‐rank test. Results The final sCT prediction model demonstrated high image similarity to pCT, with a MAE and SSIM of 38.93 ± 14.79 Hounsfield Units (HU) and 0.92 ± 0.05 for the thoracic region, and 73.60 ± 22.90 HU and 0.90 ± 0.03 for the abdominal region, respectively. There were no statistically significant differences between sCT and pCT plans in terms of organ‐at‐risk and target volume DVH parameters, including maximum dose (Dmax), mean dose (Dmean), dose delivered to 90% (D90%) and 50% (D50%) of target volume, except for minimum dose (Dmin) and (D10%). Conclusion With demonstrated high image similarity and adequate dose agreement between sCT and pCT, our study is a proof‐of‐concept for using deep learning predicted sCT for a simulation‐free treatment planning workflow for VMAT‐based LRT.

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.
