ABSTRACT Background Sunlight has profound impacts on physical and mental health, beyond vision, including effects on circadian rhythms, alertness, mood, and sleep. A family history of any mood disorders is strongly associated with psychiatric disorders including bipolar disorder. The purpose of this study was to evaluate the association between a family history of any mood disorder in patients with bipolar I disorder and solar insolation at varied international onset locations. Methods Data for this analysis were available from 5842 patients with a diagnosis of bipolar I disorder obtained at 83 collection sites in both hemispheres. This included 4752 patients from 71 collection sites in the northern hemisphere and 1090 patients from 12 collection sites in the southern hemisphere. Patient data variables were obtained from records or interviews. Solar insolation data were obtained from The National Aeronautics and Space Administration (NASA) Power database for each onset location, and the ratio of the mean monthly minimum/mean monthly maximum solar insolation was calculated. Typically, the ratio is largest near the equator (little yearly change in solar insolation) and smallest near the poles (large yearly change in solar insolation). Results A significant relationship was found between a family history of any mood disorder, the ratio of the mean monthly minimum/mean monthly maximum solar insolation, and gender. The odds of a family history of mood disorder increased as patient location nears the poles and decreased near the equator. Female gender also increased the odds of having a family history of a mood disorder. Conclusions This study highlighted the association between family history, solar insolation, and gender in international patients with bipolar I disorder. Given the profound effects of sunlight on human health, the family of patients with bipolar disorder who live in the same location with the same solar insolation, and especially females, may be at increased risk for a mood disorder.

Background: Tumor mutational burden (TMB) is an FDA-approved biomarker for immune checkpoint inhibitor (ICI) therapy. However, its predictive value varies among tumor types and molecular contexts. We investigated whether a very high TMB identifies a biologically distinct subset and whether a higher cutoff provides additional clinical insights beyond the conventional high TMB threshold. Methods: We analyzed 133 patients with advanced solid tumors and TMB ≥ 10 mutations/Mb (mut/Mb) who underwent tumor genomic profiling using a 523-gene DNA/RNA next-generation sequencing panel. Tumors were stratified into prespecified TMB categories: 10–20 mut/Mb (TMB-H) and >20 mut/Mb (TMB-VH). The clinical characteristics, ICI outcomes (in the treated subset), and pathway-level genomic features were compared between groups. Results: TMB-VH was observed in 42/133 (31.6%) patients and spanned more than 20 tumor types. MSI was markedly more prevalent in TMB-VH than in TMB-H tumors (38.1% vs. 2.2%; Fisher’s exact p = 8.9 × 10−8). Pathway-level comparisons did not identify statistically significant differences after false discovery rate correction (all q > 0.05), and the observed patterns were descriptive in nature. In the ICI-treated subset with complete follow-up, objective response did not differ according to the TMB group. Overall survival (OS) was also similar between groups, whether measured from metastatic diagnosis (log-rank p = 0.937) or from ICI initiation (log-rank p = 0.814), although OS was numerically longer in the TMB-VH group in both analyses without reaching statistical significance. Conclusions: In this cohort study, TMB-VH was strongly associated with MSI but not independently associated with improved ICI outcomes. Larger multicenter cohorts are needed to validate pathway-oriented patterns and clarify the clinical utility of extreme TMB thresholds across various histologies. Integrating the functional context (e.g., MSI status, gene-level context, and pathway-level features) with TMB magnitude may enable more robust, tumor-aware biomarker models for immunotherapy selection.

Introduction Psychological comorbidities can negatively impact outcomes of spinal cord stimulation (SCS) for chronic pain. While psychological assessment is commonly required before SCS implantation, evidence supporting its impact on outcomes is limited, and such assessments may be unnecessary for many patients and contribute to delays in care. Our center implemented a screening tool incorporating validated questionnaires and a mental health checklist to triage the need for formal psychological evaluation. This prospective, observational cohort study compared outcomes of SCS trials and implants between patients who bypassed (fast track: FT) versus those who underwent a formal assessment by a psychologist (AP). Methods Data were collected from patients undergoing SCS trials between July 2017 and December 2021. The screening tool used thresholds on validated questionnaires assessing anxiety, depression, catastrophizing, and opioid misuse risk, along with a checklist capturing significant anxiety or depression, self-harm, substance abuse, or mental-health-related hospitalization. Patients screening positive underwent an AP; others proceeded directly to trial (FT). 1 year post implantation outcomes were collected, with successful implantation defined as ≥30% pain reduction from baseline. Results Of 171 patients (114 AP, 57 FT), trial-to-implant rates were similar (72% AP vs 70% FT, p=0.811). The proportion of responders at 1 year post implant was also comparable (53% AP vs 60% FT, p=0.927). Multivariate logistic regression identified that higher baseline pain intensity (adjusted OR (aOR) 0.70, 95% CI 0.53 to 0.92, p=0.011) and use of tricyclic antidepressants (aOR 0.15, 95% CI 0.04 to 0.56, p=0.005) were associated with implant failure, whereas pain duration >10 years was associated with implant success (aOR 3.09, 95% CI 1.06 to 9.02, p=0.039). Conclusions This screening tool effectively identifies patients who can bypass routine psychological assessment without compromising 1 year SCS outcomes. Implementation can streamline patient flow, reduce wait times, and reserve psychological resources for those who need formal evaluation.

Background Antitumor immune responses induced by oncolytic immunotherapy (OI) are often followed by upregulation of programmed death-ligand 1 (PD-L1). As such, the combination of OI with blockade of the programmed cell death protein-1 (PD-1)/PD-L1 axis has demonstrated therapeutic activity in preclinical and clinical trials. The purpose of this study is to understand further the immune-mediated mechanism of interaction between oncolytic viruses and anti-PD-1 therapy. Methods Tumor cells and immune cells (splenocytes) were cultured separately, or in co-culture with vusolimogene oderparepvec, an oncolytic herpes simplex virus expressing the fusogenic gibbon-ape leukemia virus-fusogenic membrane glycoprotein protein (GALV) and granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as RP1. Viral replication, interferon (IFN) responses and PD-L1 expression were analyzed using wild-type, IFNAR1, TNFAR1 and STING knockout splenocytes. In vivo studies evaluated immune cell infiltrates into the tumor following RP1 administration with anti-PD-1 therapy. Results RP1 replication was evident in tumor cells but not splenocytes. This was also accompanied by upregulated IFN expression in cultured splenocytes that was absent in cultured tumor cells. However, when these cell types were co-cultured, splenocytes mediated an interferon response to RP1 via STING that was transmitted to tumor cells in a non-touch-dependent manner. Tumor cells responded to these input signals via upregulation of cell surface major histocompatibility complex-I and PD-L1 through tumor intrinsic JAK-STAT signaling. In vivo, an IFN signature was observed following intratumoral injection of RP1, both in injected and non-injected tumors, which was further increased when combined with anti-PD-1 therapy. Marked upregulation of PD-L1 was observed in tumors injected with RP1 accompanied by the recruitment of CD11b+Ly6G+neutrophils into the tumor microenvironment, which stained positive for PD-L1. Conclusion Overall, the data demonstrate that RP1 remodels the tumor microenvironment through a combination of direct and indirect effects on both tumor and immune cells, resulting in an overall more inflamed phenotype.

Purpose: Subcortical functional brain mapping is a valuable technique, especially involving lesions within or near white matter tracts. Motor and language deficits caused by intraoperative damage to these subcortical fibers are associated with worse outcomes. However, there are variable approaches to performing subcortical functional brain mapping. This systematic review was performed to better understand indications and optimal stimulation parameters. Methods: A systematic review was performed by PRISMA guidelines, using PubMed, Scopus, and Medline databases. Search dates ranged from inception to November 30th, 2024. Studies included adults who underwent subcortical electrical stimulation for functional brain mapping. Results: A total of 55 articles (249 patients, mean age 44.8 years, 114 female) were included. The most common pathology was brain tumor (96.3%), primarily gliomas and metastases, and 24.4% of all cases had a history of epilepsy. The most frequently mapped white matter tracts were the arcuate fasciculus, corticospinal/pyramidal tract, and inferior fronto-occipital fasciculus, involving motor, language, and cognitive functions. Bipolar stimulation (50–60 Hz, 0.5–1 millisecond, 1–10 mA) was preferred over monopolar stimulation. Among 147 patients with outcome data, 89.1% did not suffer permanent adverse outcomes including neurologic deficits, although long-term outcomes were inconsistently reported. Conclusions: The methodologic variability of subcortical functional brain mapping and lack of long-term follow-up reported limits determination of optimal parameter selection for electrical stimulation although common trends are reported. Functional brain mapping approaches may be guided by the tract and network involved. Further studies are needed to develop a standardized approach and more definitive guideline to its performance.

The systemic impairment that accompanies liver cirrhosis is known to carry a significant burden on death and postoperative complications in cardiovascular interventions. This review analyzes the impact of liver cirrhosis on short‐ and long‐term outcomes after cardiac surgery and percutaneous procedures, providing an evidence‐based guidance in the decision‐making process and perioperative management of these patients. Several parameters should be considered by the heart teams when assessing eligibility, indications for intervention, and perioperative management of these patients. Life expectancy, long‐term procedural outcomes, Child–Pugh or the Model for End‐Stage Liver Disease score, presence of gastroesophageal varices and hepatic venous pressure gradient were extrapolated as the main determinants in decision making in patients with cirrhosis. Assessment and treatment of gastroesophageal varices is mandatory. Hepatic venous pressure gradient values >20 mm Hg preclude patients from a surgical approach. Considering the poor prognosis of advanced liver cirrhosis, futile treatments should be avoided. A multidimensional heart team approach involving surgical, cardiologic, anesthesiologic, hepatological, and medical considerations is recommended.

CEUS is a safe and cost-effective means for characterization of indeterminate renal masses, with performance equal to or better than that of contrast-enhanced CT or MRI for stratification and surveillance of cystic renal masses and discrimination of benign avascular cysts from solid renal masses.

Abstract Objectives: In the RadComp randomized trial, we compared radiation dose to cardiac substructures in patients treated with proton versus photon radiation therapy (RT) ; evaluated changes in cardiac-specific health-related quality of life (HRQOL) outcomes from baseline to 6 months following RT; and determined associations between radiation dose volume histogram (DVH) parameters and changes in cardiac-specific HRQOL. Methods: The study cohort included patients with locally advanced breast cancer enrolled on RadComp who completed treatment per protocol, had available radiation DVH metrics for all cardiac substructures, and completed both the baseline and at least one follow-up cardiac-specific HRQOL over the 6 months post-RT. Cardiac-specific HRQOL measures included PROMIS fatigue, PRO-CTCAE shortness of breath (SOB) (severity and interference with daily activities), and PRO-CTCAE chest pain, chest tightness, and angina (frequency, severity, and interference). Detailed dose volume histograms (DVH) for cardiac substructures included the whole heart, left ventricle (LV), right ventricle (RV), left atrium (LA), right atrium (RA), and left anterior descending artery (LAD) were derived. The Wilcoxon rank-sum test was used to compare dose distributions between photon and proton RT. Associations between DVH metrics and HRQOL outcomes were evaluated using repeated-measures linear regression via generalized estimating equations with an independent working correlation structure. All models were adjusted for RT type, age, cardiovascular risk factors, surgery type, laterality, ethnicity, education, timepoint, and race. Additional stratified analyses was performed according to laterality (right versus left + bilateral). Results: Across 1160 RadComp participants, RT exposure to cardiac substructures differed significantly between proton and photon RT and by laterality. Median mean heart dose was lower with protons, 0.9 Gy (Q1, Q3 0.49, 1.46), compared to photons 2.83 Gy (Q1, Q3 1.49, 4.52) (p< 0.001), and lower for right-sided disease, 0.91 Gy (Q1, Q3 0.44, 1.55), compared to left and bilateral 1.99 Gy (Q1, Q3 1.11, 3.63) (p<0.001). Similarly, for the LAD, LA, LV, and RA, mean proton dose was significantly lower (p<0.001). However, for the whole heart, RA, and RV, maximum doses to small-volume parameters and dose to 0.03cc were higher with proton RT. PRO-CTCAE measures of HRQOL were generally favorable at all timepoints across all participants, and grade ≥3 toxicity was rare (≤5.5%) for all measures. The PROMIS Fatigue T-Score increased from baseline (median 49 [Q1, Q3 46, 57]) to end of RT (55 [Q1, Q3 49, 63]), and returned to baseline levels at 6 months (p<0.001). While there were no significant differences in PRO-CTCAE SOB severity (p=0.24) and interference (p=0.11) over time, PRO-CTCAE chest pain worsened compared to pre-RT with respect to frequency (p<0.001), severity (p<0.001), and interference (p=0.008). However, the absolute changes were small. No DVH metrics were significantly associated with any cardiac-specific HRQOL outcomes. Stratification by laterality yielded similar results. Conclusions: Proton RT generally conferred significantly lower doses to the heart and cardiac substructures compared to photon RT. HRQOL outcomes were favorable across all participants, with fatigue returning to baseline, no change in SOB parameters, and a slight worsening of chest pain outcomes over 6 months following RT. Cardiac-specific HRQOLs appear not to be significantly affected by RT dose to cardiac substructures within the first 6 months post-RT. Other organs at risk that could also impact cardiac HRQOL endpoints, longer follow-up, and major cardiac events will be evaluated in future analyses. Citation Format: J. L. Wright, K. Ko, W.

Abstract Background: Two years of adjuvant abemaciclib plus endocrine therapy is approved and guideline-recommended in patients (pts) with HR+, HER2-, node-positive, early breast cancer (EBC) at high risk of recurrence. In initial real-world studies, the high rate (>85%) of treatment (tx) persistence beyond 3 months suggests that adjuvant abemaciclib is well-tolerated in routine clinical practice.1,2 Dose reductions were associated with higher persistence in prior studies and clinical trial data have shown that efficacy of abemaciclib was maintained with dose reductions. This study describes 6-month tx persistence and dosing patterns in pts with HR+, HER2-, node-positive EBC initiating abemaciclib 150 mg twice daily (BID). Methods: Retrospective data were accessed from the US de-identified Flatiron Health Research Database. Adults with HR+, HER2-, node-positive, EBC, who initiated abemaciclib 150 mg BID from Jan 2022-Jun 2024 were eligible and further characterized by ≥1 vs no dose reduction. Data cut-off was Dec 2024. Persistence rate was the proportion of pts on abemaciclib >6 months, allowing for ≤60-day medication gap within this period. Time to dose modifications and reasons for discontinuation (DC) were summarized. Subgroup analyses were conducted in pts confirmed as meeting the monarchE high-risk criteria (N2, N3, or N1 plus Grade 3 and/or tumor >5 cm). All analyses were descriptive. Results: Of 1063 eligible pts, median age was 56 years (IQR 47, 65). Most had N1 (48%) or N2 (34%) disease. Median follow-up was 17.5 months (IQR 11, 25). Tx persistence at 6 months was 75%. DC was mostly due to adverse events (AEs; 19%) and <1% due to recurrence. Approximately 50% of pts had ≥1 dose reduction. Persistence was 85% in pts with ≥1 dose reduction and 64% in pts with no dose reductions. 70% of pts who DC’d by 6 months did not have a dose reduction. Median time from start of abemaciclib to first dose change and/or hold was 49 days (IQR 23, 111). During the first 30 days of tx and Days 31-90, DCs due to AEs were lower in pts with dose reductions vs pts with no dose reductions (Table). Persistence and use of dose reductions were similar in pts confirmed as meeting the monarchE high-risk criteria. Conclusion: In US clinical practice, a majority (75%) who initiated adjuvant abemaciclib continued abemaciclib beyond 6 months. Tx persistence was higher among pts with dose reductions relative to those with no dose reductions, and rates of early DCs due to AEs were low in pts with dose reductions. Given that dose reductions in monarchE were not associated with reduced efficacy, these additional real-world data support the use of early dose modifications to improve tolerability and tx persistence for adjuvant abemaciclib in pts with high risk of recurrence.
