Abstract Objective To describe the presenting symptoms, treatment regimens, and outcomes associated with oropharyngeal adenoid cystic carcinoma. Data Sources Ovid MEDLINE(R), Ovid Embase, Ovid Cochrane Central Register of Controlled Trials, and Scopus via Elsevier. Review Methods This review followed the Preferred Reporting Items for Systematic Reviews and Meta‐analyses. A medical librarian conducted the literature search using controlled vocabulary and keywords, with investigator input. Eligible articles were clinical trials and observational studies reporting on clinical features, treatment, or outcomes for oropharyngeal adenoid cystic carcinoma. Results Our search identified 233 unique citations, with 44 articles included covering 195 patients. The female‐to‐male ratio was 1.7:1, and the base of the tongue was the most common subsite (73%). Presenting symptoms were mainly pain/discomfort (n = 31), followed by a palpable mass (n = 19) and dysphagia (n = 12). At diagnosis, 22.3% (29 patients) had positive lymph nodes. Treatment was primarily surgical (n = 102), with definitive radiation therapy used in 58 cases. Disease progression was noted in 86 patients, 36% (n = 31) of whom developed distant metastases—primarily to the lungs (n = 26). Long‐term outcomes (n = 76) showed 3‐ and 5‐year overall survival rates of 71.5% to 100% and 47.6% to 79.0%, and disease‐free survival rates of 54.7% to 70.0% and 21.9% to 44.0%, respectively. Conclusion Among patients with available data, oropharyngeal adenoid cystic carcinoma appeared more common in women and has a predilection for the base of the tongue. However, this finding should be interpreted with caution, given the high proportion of missing data. These tumors appear to carry a higher risk for nodal metastases and may lead to poor outcomes.

Abstract Background Recent studies suggested that treating obesity and its comorbidities with glucagon-like peptide-1 (GLP-1) receptor agonists may improve outcomes in patients with heart failure with preserved ejection fraction (HFpEF). The randomized SUMMIT trial found that tirzepatide use was associated with a lower risk of heart failure (HF) events or cardiovascular death in adults with HFpEF and obesity compared with placebo. Purpose We aimed to examine whether tirzepatide use in clinical practice was associated with risks of HF events and all-cause mortality among adults with HFpEF and obesity. Methods This was a retrospective cohort study leveraging the Optum Labs Data Warehouse (OLDW), a de-identified administrative claims database of commercial and Medicare Advantage enrollees across the United States. We identified all adults with HFpEF and obesity from January 1, 2022, to December 31, 2024. Our primary exposure was tirzepatide use, and our primary outcome was a composite of a HF event (ED visits or hospitalization for HF) or mortality. Secondary outcomes included hospitalization for angina, atrial fibrillation or atrial flutter (AF/AFL), acute myocardial infarction (MI), cardiac arrest, and cardiogenic shock. Patients were followed from the index date, defined as the tirzepatide treatment start date after HFpEF diagnosis or pseudo-index date in tirzepatide non-users, to the end of enrollment or death using the intention-to-treat framework. Inverse probability of treatment weighting (IPTW) was used to balance groups. Fracture, conjunctivitis, ear infection, and fungal skin infection were used as falsification endpoints. Cox-proportional and Fine-Gray subdistribution hazard models were used to estimate a hazard ratio (HR) and subdistribution hazard ratio (SHR), respectively. Results Among our total cohort of 99,270 patients, the mean age was 73 years, 58,616 (59.1%) were female, 8,839 (8.9%) used tirzepatide, and the mean follow-up time was about 385 days. Patients using tirzepatide had a significantly lower risk of a HF event or mortality (HR=0.73; 95% confidence interval [CI]=0.66–0.80; p<0.001) compared to patients not using tirzepatide. Patients using tirzepatide had a lower risk of a HF event (SHR=0.80; 95% CI=0.73–0.88; p<0.001) and all-cause mortality (HR=0.48; 95% CI=0.38–0.60; p<0.001). Tirzepatide use was associated with lower risks of hospitalization for acute MI (SHR=0.67; 95% CI=0.52–0.85; p=0.001) and cardiogenic shock (SHR=0.56; 95% CI=0.38–0.83; p=0.003), but not angina, AF/AFL, or cardiac arrest (Figure 1). Conclusion Among adults with HFpEF and obesity, tirzepatide use in real-world clinical practice was associated with a lower risk of HF events, hospitalizations for acute cardiovascular disease, and all-cause mortality.For image description, please refer to the figure legend and surrounding text.

ABSTRACT MYH11 ‐related hereditary type 2 visceral myopathy is a rare smooth muscle disorder typically presenting in infancy with severe gastrointestinal and genitourinary dysfunction. We describe a 73‐year‐old female with lifelong symptoms of gastrointestinal and urinary dysfunction, including chronic constipation, neurogenic bladder, recurrent urinary tract infections, gastroparesis, and pelvic organ prolapse. A multigenerational family history revealed similar visceral smooth muscle abnormalities among 14 affected individuals over five generations, suggesting autosomal dominant inheritance. Whole‐genome sequencing identified a heterozygous, likely pathogenic variant in MYH11 c.5819del; p.(Pro1940HisfsTer91), consistent with the diagnosis of autosomal dominant type 2 visceral myopathy. This variant causes production of an abnormally elongated myosin‐heavy chain, disrupting muscle contractile function. This individual's survival into her eighth decade reflects long‐term clinical stability, possibly attributable to the variant's milder effect. We describe the clinical course of the disease, along with a comprehensive review of previously described individuals with the same variant. This case broadens the phenotypic spectrum of MYH11 ‐associated visceral myopathy, demonstrating that late‐onset, milder forms can occur and remain compatible with long‐term survival with optimal supportive management. Comprehensive genetic evaluation identifies primary disorders, enabling precise diagnosis, tailored management, and informed genetic counseling for complex phenotypes.

Abstract Background Lysosomal dysfunction plays a crucial role in the pathogenesis of Parkinson’s disease (PD), particularly among GBA1 mutation carriers. Beyond GBA1 , genes such as TMEM175 , SCARB2 , and CTSB identified in genome-wide association studies (GWAS) are also implicated in lysosomal pathways contributing to PD risk, although their functional effects in patients remain unclear. Proteins encoded by these lysosome-related genes have been explored as potential therapeutic targets in experimental models. Biomarker profiles, including clinical measures, α-syn seeding activity, lysosomal proteins, and sphingolipids, may facilitate patient stratification and support therapeutic monitoring in future clinical trials. Aim The aim of this study is to investigate the impact of genetic variants of three lysosomal-related genes ( TMEM175 , SCARB2 , and CTSB ) on biomarker profiles in PD with and without GBA1 variants. Cross-sectional data from two German cohorts: the Tuebingen Parkinson Cohort (TUEPAC) and the DESCRIBE PD cohort of the German Center for Neurodegenerative Diseases were used as explorative cohorts, and data from Accelerating Medicines Partnership® Parkinson’s Disease (AMP-PD) were used as a validation cohort. The ultimate goal is to provide new data for patient stratification based on genetics, which might serve as a readout for target engagement and treatment efficiency assessment. Methods Three cohorts were analyzed: TUEPAC, DESCRIBE PD, and AMP-PD. TUEPAC and DESCRIBE PD were combined into a single German discovery cohort (TUEPAC-DESCRIBE-PD), while AMP-PD served as an independent validation cohort. Within each cohort, for subgroup analyses, PD patients were classified as the overall PD cohort (PD all ), and further stratified by GBA1 mutation status into PD patients without GBA1 mutations (PD GBA1 _wildtype ), and PD patients carrying GBA1 mutations (PD GBA1 ). We evaluated cognitive and motor function, as well as depression using the Montreal Cognitive Assessment (MoCA), Unified Parkinson Disease Rating Scale-part I II (UPDRS III), and Beck Depression Inventory-II(BDI-II) scales. Analyzed biomarkers included CSF α-syn seeding activity using seed amplification assay (SAA), CSF lysosomal protein levels of lysosomal integral membrane protein 2 (LIMP2), also known as SCARB2, cathepsin B (CTSB) and lysosome-associated membrane protein 2 (LAMP2), blood-based enzyme activity of the lysosomal glucocerebrosidase (GCase), and CSF sphingolipid profiles. PD patients carrying risk alleles in TMEM175 , SCARB2 , and CTSB were compared to non-carriers. Results Genotype-phenotype correlation analysis in TUEPAC-DESCRIBE-PD and AMP-PD revealed: (1) In PD all , the TMEM175 p.M393T risk variant was nominally associated with decreased cognitive function when adjusted for GBA1 mutation status in TUEPAC-DESCRIBE-PD; this association could not be replicated, although a similar trend was observed in the slightly smaller, but multicentric AMP-PD cohort; TMEM175 p.M393T was not significantly associated with BDI-I I or UPDRS-III scores in either cohort. (2) In PD GBA1 _wildtype , GCase activity was significantly lower in PD patients with SCARB2 rs6812193 risk allele in TUEPAC-DESCRIBE-PD, while a similar but non-significant trend was observed in AMP-PD; (3) In PD all , CSF levels of CTSB were nominally lower in carriers of CTSB rs1293298 risk allele compared to carriers of CTSB rs1293298 protective allele in TUEPAC-DESCRIBE-PD; in PD GBA1 _wildtype , LAMP2 was significantly lower in carriers of CTSB rs1293298 risk allele compared to carriers of CTSB rs1293298 protective allele in TUEPAC-DESCRIBE-PD; (4) In PD all , TMEM175 p.M393T risk allele was nominally associated with altered sphingolipid profiles across both TUEPAC-DESCRIBE-PD and AMP-PD cohorts. Conclusion These findings demonstrate that genetic variants in lysosomal-related genes ( TMEM175 , SCARB2 , and CTSB ) have a functional impact on biomarker profiles in PD patients. Integrating genetic characterization with biochemical profiling provides a framework for patient stratification and may serve as a translational strategy to monitor target engagement and evaluate treatment efficacy in future clinical trials.

Abstract Background Cardiovascular implantable electronic device (CIED)-associated infective endocarditis with large vegetations carries substantial morbidity and a high risk of embolization during transvenous lead extraction (TLE). Purpose To evaluate procedural outcomes, microbiological clearance, and embolic risk in patients undergoing percutaneous aspiration of vegetations in the setting of CIED-associated infective endocarditis prior to TLE. Methods Between January 2023 and October 2025, patients with confirmed CIED-associated infective endocarditis and echocardiographic evidence of vegetations on transvenous leads or cardiac valves were included. Mechanical aspiration was performed at the operator’s discretion for vegetation size > 20 mm, multiple vegetations, prior or potential embolization risk, or ongoing sepsis. All patients underwent percutaneous aspiration using the AngioVac or Penumbra system, followed by TLE either during the same session or in a staged procedure. Baseline clinical characteristics, microbiologic data, procedural details, and outcomes were reviewed. Results Our cohort comprised five patients (60% male) with a median age of 56.8 years (IQR 49.4–66.1). Median lead dwell time was 6.1 years (IQR 3.9–14.8). Median vegetation size was 12.5 mm (IQR 8–17). Two patients had prior septic pulmonary emboli. Microbiology identified Staphylococcus aureus in 2, Streptococcus spp. in 2, and Salmonella spp. in 1. The tricuspid valve and lead were involved in 4 patients, the mitral valve in 2, and the aortic valve in 1. The AngioVac system was used in 4 cases and Penumbra in 1. Successful aspiration (≥70% reduction in vegetation size of the targeted valve) was achieved in all cases. Two patients underwent staged extraction and three underwent concomitant TLE with complete removal of the transvenous system. A total of 8 leads were extracted (median 1, IQR 1–2.5); 4 patients had ICD leads, 2 with dual coil. No clinically significant embolic events occurred during the procedures. Among two patients with persistent infection, blood cultures cleared within 24 hours in one and 96 hours in the other. There were no major procedural complications or in-hospital or 30-day mortality. One patient with multivalvular involvement (aortic, mitral, tricuspid) subsequently underwent valve replacement surgery after blood cultures became sterile post-aspiration and TLE. Conclusion Percutaneous mechanical aspiration of vegetations prior to TLE was feasible and safe, resulting in effective microbiological clearance without periprocedural embolic events or major complications. This approach provides a viable alternative to surgical extraction in selected high-risk patients with large vegetations and device-related infective endocarditis and helps control sepsis.TEE images of the TV vegetationMacroscopic image of the vegetation

The adult chronic pancreatitis (CP) working group, formed at the inception of the Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer (CPDPC), has developed a robust framework and infrastructure to conduct clinical, translational, and mechanistic studies of CP. At its core is PRO spective Evaluation of C hronic Pancreatitis for E pid E miologic and Translational Stu D ies (PROCEED), the first longitudinal cohort study of CP in US adults, launched in 2017. PROCEED has developed a well-annotated clinical data set of over 2000 deeply-phenotyped participants, a biorepository and an imaging repository. Investigators have published promising data on blood-based and imaging-based biomarkers of CP diagnosis and pain, which are awaiting validation. Clinical observations include classification of patients into mechanism-based pain phenotypes using responses to PROMIS questionnaires, prevalence and predictors of opioid use, prevalence of psychological comorbidity, and osteopathy in CP patients. Pilot clinical trials have evaluated the effect of oral indomethacin on pancreatic fluid prostaglandin E2 levels and Internet-based cognitive behavioral therapy (CBT) for chronic pain. Results of pilot trials have led to an ongoing definitive randomized clinical trial for CBT. The rich environment and resources have facilitated mentorship and academic development of many early-stage investigators. Investigators outside of the consortium have opportunities for collaboration. In the next 5 years, the working group plans to further strengthen the research platform, complete primary and key secondary analyses of PROCEED and ancillary studies, continue efforts to develop biomarkers for diagnosis and prognosis of CP, and complete ongoing clinical trials to address unanswered questions in the field.

Objectives Rheumatoid factor (RF) and anticitrullinated protein antibodies (ACPA) are linked to disease activity, severity and cardiovascular risk in rheumatoid arthritis (RA). Since RA-related inflammation associates with cardiovascular disease, we investigated whether RF and ACPA status influence the relationship between RA activity and event risk. Methods We assessed 3952 cardiovascular disease-free patients with prevalent RA registered in an international observational consortium between 1985 and 2012. Main outcome was a first major adverse cardiovascular event (MACE) including myocardial infarction, stroke and cardiovascular death. Follow-up accrued from enrolment until first MACE or censoring. Multivariable Cox models stratified by centre risk evaluated disease activity, RF, ACPA and their interactions. Results We recorded 184 first MACE events over 22 981 patient-years. Disease activity associated with MACE (HR 1.18 (95% CI 1.03 to 1.35)), whereas RF (HR 1.26 (0.82 to 1.94)) and ACPA (HR 1.25 (0.85 to 1.83)) did not reach statistical significance, though CIs were wide and a clinically meaningful association cannot be excluded. A three-way interaction between disease activity, RF and ACPA on MACE (p for interaction=0.044) was observed. RA activity associated with MACE in seronegative and double seropositive (p≤0.047), but not single RF-positive or ACPA-positive patients. Among RF-negative participants, RA activity was linked to MACE in ACPA-negative but not positive ones (p for interaction=0.003). Among ACPA-positive patients, disease activity was linked to MACE in RF-positive but not RF-negative ones (p for interaction=0.040). Conclusions Disease activity may better discriminate inflammation-driven cardiovascular risk in seronegative and double seropositive than single RF-positive or ACPA-positive patients. Risk protection through lowering disease activity may be serostatus dependent.

Abstract Background Approximately 12,000 adolescents and young adults (ages 15-39, AYAs) are diagnosed with a primary central nervous system (CNS) tumor each year. DNA methylation profiling has transformed CNS tumor classification by refining diagnostic accuracy and identifying biologically distinct subtypes, but its application has not been systematically evaluated in the AYA population. In this study, we examined the spectrum of CNS tumor types across age groups, with a focus on the AYA population. Methods We assembled a large dataset of CNS tumor samples with age annotations and methylation profiles matching with high confidence to a CNS tumor type using the NCI/Bethesda classifier. Prevalence of tumor type, methylation class and DNA copy number aberrations were compared across age strata (pediatric, AYA and adult). Results The cohort of 21,099 CNS tumors included 5139 tumors from AYAs (24%), which showed a mixed pattern, with tumors typical of childhood (e.g. medulloblastoma) as well as those common in older adults (e.g. glioblastoma). Several tumor types were specifically enriched in the AYA, including IDH-mutant astrocytoma, pleomorphic xanthoastrocytoma, posterior fossa group B ependymoma, and diffuse hemispheric glioma, H3 G34-mutant, among others. Distinct methylation subclasses of multiple tumor types were observed in the AYA, and patterns of genomic aberrations showed age-specific distributions. Conclusion Large-scale methylation profiling revealed unique classification patterns of CNS tumors in AYAs, with specific tumor types, subclasses, and genomic alterations enriched in this population. These data may serve as a valuable reference resource for better understanding the spectrum of CNS tumors affecting AYA patients.

Abstract Myelodysplastic syndromes (MDS) are clinically and biologically diverse disorders, emphasizing the need for personalized treatment approaches. The International Working Group for Prognostication of MDS (IWG_PM) recently introduced a molecular classification, referred to as the MDS taxonomy, that categorizes patients into 16 subgroups based on 21 gene mutations, 6 cytogenetic abnormalities, and loss of heterozygosity (LOH) at TP53 and TET2 loci. This study sought to validate and enhance the clinical relevance of the MDS taxonomy by analyzing a large retrospective cohort ( n = 5136) and transcriptomic data from a prospective cohort ( n = 477). The taxonomy successfully identified subgroups with distinct clinical characteristics and disease progression patterns. However, incorporating gene interactions from taxonomy subgroups did not improve the prognostic performance of the Molecular International Prognostic Scoring System (IPSS‐M). We further assessed whether the taxonomy could guide management in patients receiving disease‐modifying therapies. Except for the “ TP53 ‐complex” subgroup, taxonomy classifications were not predictive of hypomethylating agent response or transplant outcomes. Nonetheless, they correlated with overall survival, suggesting that while both IPSS‐M and the taxonomy capture disease biology, other non‐genetic factors may influence treatment response. RNA sequencing confirmed the biological distinctiveness of the taxonomy groups. Transcriptomic profiling of CD34+ bone marrow cells revealed unique, homogeneous gene expression patterns, particularly within the AML‐like, bi TET2 , SF3B1 , and TP53 ‐complex subgroups. Further integration of multi‐omics data may refine MDS classification, improving clinical decision‐making and guiding the development of targeted therapies.
