Abstract Background Dystonia and Parkinson's disease (PD) exhibit clinical and genetic overlap, but the relevance of dystonia gene variants in PD remains unclear. Objective The aim was to assess the frequency of dystonia‐linked pathogenic variants in PD. Methods We screened sequencing data from 15,684 individuals (8272 PD, 3200 atypical parkinsonism, and 4212 unaffected) from the Global Parkinson's Genetics Program (GP2) and Accelerating Medicines Partnership‐Parkinson's Disease (AMP‐PD) for variants in genes linked to isolated dystonia, dystonia‐parkinsonism, and myoclonus‐dystonia. Results Pathogenic variants were identified only in PD patients. Forty‐five PD individuals (0.54%) carried 26 distinct (likely) pathogenic variants in nine dystonia‐linked genes, most frequently in GCH1 , followed by VPS16 . Conclusion Though rare, pathogenic variants in dystonia‐linked genes are present in clinically and pathologically diagnosed PD. Our results reinforce GCH1 as a PD‐relevant gene with clinical implications, whereas variants identified in other genes are rare and of uncertain relation to the PD phenotype. © 2025 The Author(s).

Metastatic castration-resistant prostate cancer (mCRPC) progresses aggressively and resists existing therapies. Although poly(ADP-ribose) polymerase inhibitors (PARPis) benefit a subset of patients with mCRPC and BRCA1/2 deficiencies, therapeutic options remain limited for those without such mutations. Here, we uncover a critical role for the ATM-TRMT10A-BRCA1 signaling axis in regulating homologous recombination (HR) repair and PARPi sensitivity. We demonstrate that ATM phosphorylates TRMT10A at serine-28 after DNA damage, promoting BRCA1 recruitment and efficient HR repair. TRMT10A deletion disrupts HR repair, sensitizing cells to PARPis. Moreover, TRMT10A is up-regulated in mCRPC through stabilization by USP10. Targeting USP10 with spautin-1 induces TRMT10A degradation and enhances tumor sensitivity to PARPis in cell-derived xenografts and patient-derived xenograft models. These findings identify TRMT10A as a therapeutic vulnerability in mCRPC and demonstrate that combined inhibition of PARP and USP10 offers a promising synthetic lethal strategy for a broader group of patients lacking classical BRCA mutations.

ABSTRACT Background Patients with cancer undergoing cardiac implantable electronic device (CIED) implantation face unique challenges. This study evaluates the outcomes and implications of CIED implantation in this population. Methods Using data from the National Readmission Database (NRD) from 2016 to 2019, we analyzed CIED implantations in patients aged ≥18 years, categorized by cancer status: no cancer, historical cancer, and active cancer. Multivariable logistic and linear regression models assessed associations with in‐hospital, 30‐day, and 90‐day outcomes, adjusting for various patient characteristics. Results A total of 748,957 CIED procedures were analyzed among which 13.3% were in patients with historical cancer and 3.8% with active cancer. Active cancer was linked to higher odds of pacemaker implantation but lower odds for ICD and CRT devices. Patients with active cancer experienced higher index hospitalization mortality (aOR 1.68; 1.50–1.89; p < 0.001), major adverse cardiovascular events (aOR 1.07; 1.02–1.14; p = 0.01), bleeding (aOR 1.36; 1.27–1.46; p < 0.01), and sepsis‐related (aOR 1.31; 1.19–1.44; p < 0.01) complications, with increased readmission rates at 30 (aOR 1.37; 1.30–1.44; p < 0.01) and 90 days (aOR 1.37; 1.31–1.44; p < 0.01) compared to those without cancer. Historical cancer was associated with better outcomes. Key predictors of adverse outcomes included chronic heart failure, kidney disease, cerebrovascular disease, and protein‐calorie malnutrition. Conclusions Patients with active cancer undergoing CIED implantation have an increased risk of in‐hospital complications and readmissions as compared to those without cancer.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death in the United States and worldwide. HCC screening among patients at elevated risk is associated with improved early detection and overall survival, but current ultrasound-based screening strategies are challenged by low adherence and suboptimal sensitivity. Blood-based screening tests have the potential to enhance adherence and improve early-stage HCC detection if they can demonstrate favorable performance compared with ultrasound-based screening. Here we present the design and rationale for ALTUS (A lternative to Ultrasound), a prospective, longitudinal, multicenter study in the United States to investigate the performance of the multi-target HCC blood test (mt-HBT) for the detection of HCC in a screening population. Methods: Adults with liver cirrhosis or chronic hepatitis B infection will be enrolled to undergo standard-of-care screening imaging and concurrent blood collection for the mt-HBT. All participants will undergo contrast-enhanced CT or MRI imaging with central radiology LI-RADS assessment as the reference method to determine HCC status. Participants without an identified malignancy will undergo a second screening visit and blood collection, and longitudinal clinical and imaging data will be collected up to 18 months from enrollment. The primary study objectives are to demonstrate that the mt-HBT is non-inferior to ultrasound for early-stage HCC sensitivity and to assess mt-HBT HCC specificity. The secondary objective is to assess mt-HBT overall sensitivity. Results: ALTUS is in progress with readout of the primary analysis expected in 2025. Conclusions: This prospective head-to-head comparison of the mt-HBT versus ultrasound will provide novel data regarding the performance and utility of the mt-HBT for HCC screening.

Background: Chronic nonspecific low back pain (CNLBP) is a prevalent, disabling condition worldwide. Tuina, a traditional Chinese manual therapy, has shown potential benefits, but evidence remains limited. Objective: This study evaluated the effectiveness and safety of Tuina therapy in managing CNLBP in a U.S. population. Methods: A prospective, single-blind, randomized controlled trial was conducted at Mayo Clinic Rochester campus (February 2020-April 2024). 204 participants with CNLBP were randomized into 3 groups: Tuina (N = 68), physical therapy (N = 68), or a combination of both (N = 68). Each group received 6 treatments over 2 months. The primary outcome was pain intensity (VAS); secondary outcomes included disability (ODI), quality of life (SF-36), and adverse events. Additionally, participants completed a satisfaction survey at the end of the trial. Research Electronic Data Capture (REDCap) was used for survey data collection. Data was assessed by analysis of variance (ANOVA) for the multiple repeated measurements, Kruskal-Wallis tests, while Chi-square tests, and Bonferroni correction in SAS software. Results: 185 subjects completed the study. Significant decreases in VAS, ODI, and SF-36 Overall Physical scores were found from baseline, to post treatment and follow-up in all groups ( P < .05), while there were no significant differences in VAS, ODI, or SF-36 outcomes between the Tuina group and the other 2 groups. There were 4 adverse events observed in the trial, 1 in the Physical therapy group and 3 in the Mixed group. Only 1 transient low back pain after Tuina therapy was observed in the Mixed group but did not require treatment. The high percentage of patients who received the Tuina program was extremely helpful (n = 94/126, 77.0%). The willingness to recommend was significantly higher for Tuina compared to physical therapy (Mixed group [N = 59/62, 95.2%], Tuina group [N = 57/64, 91.9%], and physical therapy group [N = 31/59, 59.6%] ( P < .05). Conclusion: Tuina therapy showed comparable benefits to physical therapy and combined treatment of both in improving pain, function, and quality of life in patients with CNLBP. With high patient satisfaction and a favorable safety profile, Tuina appears to be a safe and acceptable non-invasive treatment option. Further studies are needed to validate these findings in the future.

PURPOSE Older patients with ALL receiving conventional chemotherapy have poor survival due to toxic death and relapse. We hypothesized that a chemotherapy-free, targeted regimen using the anti-CD22 antibody-calicheamicin conjugate inotuzumab ozogamicin followed by the bispecific anti-CD19/CD3 T-cell engager blinatumomab would reduce toxic death and yield high rates of prolonged remission and survival. METHODS Eligible patients were age 60 years and older with untreated, Philadelphia chromosome (Ph)–negative, CD22-positive, B-cell ALL. Patients received up to two cycles of inotuzumab ozogamicin followed by four or five cycles of blinatumomab with intrathecal methotrexate CNS prophylaxis. The primary end point was 1-year event-free survival (EFS). RESULTS The 33 eligible patients had a median age of 71 years (range, 60-84) and a median CD22 expression of 92% (range, 21%-100%). Eight (24%) had previous chemotherapy or radiation for other cancers, six for multiple myeloma. The composite complete remission rate was 85% after two cycles of inotuzumab ozogamicin and 97% by the end of two cycles of blinatumomab. At a median follow-up of 30 months, the 1-year EFS and overall survival were 75% (95% CI, 61 to 92) and 85% (95% CI, 73 to 98), respectively. EFS was shorter with lower CD22 expression or detectable measurable residual disease at any time point. CONCLUSION Inotuzumab ozogamicin then blinatumomab without maintenance chemotherapy in older patients with untreated, Ph-negative, CD22-positive, B-cell ALL yields a high remission rate and excellent EFS. Given the lack of standard, safe, and effective therapies in this population, the regimen should be considered a standard treatment option.

Background Low back pain is the leading cause of disability worldwide. Multidisciplinary approaches to chronic pain can support resilience in recovery of functioning. The ancient arts of t’ai chi and qigong have been touted for centuries as multimodal approaches to health and healing. An RCT of an on-line t’ai chi and qigong program for individuals with chronic low back pain found clinically significant improvements in pain, physical function, and quality of life. The program consisted of the integrated practice of t’ai chi movement and the stillness of qigong practice. Meditations in the program focused on developing positive mental attitudes to support resilience in managing the emotional challenges of pain and disease. Objective The purpose of the current qualitative study aimed to better understand participants’ experiences during the online Heal and Strengthen the Spine with T’ai Chi and Qigong (HSSTQ) program. Methods Written feedback was received from 96 program participants, and semi-structured interviews were completed with 20 participants. Interviews were transcribed and coded based upon the written feedback and interview questions. A thematic narrative was developed from the coded segments of texts and reviewed by participants in a member check. Results Three interlocking themes characterized the experiences of participants in the program: (1) participants learned skills to relieve back pain including moderation in movement; (2) the holistic nature of the program enabled a range of benefits for participants beyond pain reduction; and (3) personal healing experience, the enthusiasm of the instructor, the program itself, and available staff resources motivated individuals to participate. Conclusion The conclusion from this study and the initial RCT is that a virtually delivered integrated tai chi, qigong, and meditation program may be a viable treatment option for adults with low back pain.

Background: It is crucial to evaluate liver fibrosis in metabolic dysfunction-associated steatotic liver disease (MASLD). Digital pathology, an automated method for quantitative fibrosis measurement, provides valuable support to pathologists by providing refined continuous metrics and addressing inter-observer variability. Although non-invasive tests (NITs) have been validated as consistent with manual pathology, the relationship between digital pathology and NITs remains unexplored. Methods: This study included 99 biopsy-proven MASLD patients. Quantitative-fibrosis (Q-Fibrosis) used second-harmonic generation/two-photon excitation fluorescence microscopy (SHG/TPEF) to quantify fibrosis parameters (q-FPs). Correlations between eight NITs and q-FPs were analyzed. Results: Using manual pathology as standard, Q-Fibrosis exhibited excellent diagnostic performance in fibrosis stages assessment with area under the receiver operating characteristic curves (AUCs) ranging from 0.924 to 0.967. In addition, magnetic resonance elastography (MRE) achieved the highest diagnostic accuracy (AUC: 0.781–0.977) among the eight NITs. Furthermore, MRE-assessed liver stiffness measurement (MRE-LSM) showed the strongest correlation with q-FPs, particularly adjusted by string length, string width, and the number of short and thick strings within the portal region. Conclusions: Both MRE and digital pathology demonstrated excellent diagnostic accuracy. MRE-LSM was primarily determined by collagen extent, location and pattern, which provide a new perspective for understanding the relationship between the change in MRE and histological fibrosis reverse.
