Abstract Background Although periodontitis and oral microbiota are linked to cardiometabolic diseases (CMD), it is unclear if they similarly predict CMD mortality. We compared the predictive ability of salivary microbiota and periodontal disease measures for CMD mortality in the National Health and Nutrition Examination Survey (NHANES). Methods We included 5,037 adults aged ≥30 years (mean age [± standard deviation (SD)]: 48[± 14]; 50% male) from the 2009–2010 and 2011–2012 NHANES cycles. We used 16S rRNA sequencing data from saliva to operationalize microbial composition and diversity. We calculated the relative abundance log‐ratio of Treponema (linked with periodontal disease) to Corynebacterium (linked with periodontal health) to compute the Microbial Indicator of Periodontitis (MIP). Interproximal periodontal probing depth and clinical attachment loss were measured from periodontal examinations. Mortality was ascertained through 2019. Survey‐weighted Cox models regressed mortality rates on MIP, microbial diversity, and periodontal measures to estimate hazard ratios and 95% confidence intervals (HR [95% CI]). Results Over 8.8 median follow‐up years, there were 81 CMD and 267 all‐cause deaths. After multivariable adjustment, MIP was associated with increased CMD mortality risk (HR per 1‐SD: 2.10 [1.30–3.38]). Neither microbial diversity nor periodontitis measures were associated with CMD mortality. MIP was associated with periodontitis in multivariable modeling (risk ratio per 1‐SD: 1.29 [1.22–1.39]). Conclusions In a nationally representative cohort, greater baseline salivary Treponema to Corynebacterium ratio predicted increased CMD mortality risk, while microbial diversity metrics and periodontal parameters were not significantly associated with CMD mortality. Longitudinal studies that further contextualize the oral microbiota are warranted. Plain Language Summary Bacteria in the mouth that cause gum disease are linked to cardiometabolic diseases (e.g., diabetes, cardiovascular disease, kidney disease). However, it is not well understood if bacteria of the mouth can predict the risk of death due to cardiometabolic diseases. We used data from a nationwide survey of US adults to explore whether bacteria from saliva, collected from a single time point, are associated with the future risk of cardiometabolic disease death. We found that people with higher levels of gum disease bacteria were more likely to die from cardiometabolic diseases. Future studies are needed to better understand the role of gum disease bacteria in the development of cardiometabolic diseases and the risk of death.

BACKGROUND AND OBJECTIVES: While many trials of the last decade have shifted the paradigm of stroke care toward endovascular therapy, a lack of timely access to centers with neurointerventional capabilities for many patients has remained a significant barrier to care. Endovascular robotic systems are poised to address this need for expanded access through telerobotic procedures, while also benefiting clinical team safety and raising the possibility of improved procedural precision. METHODS: A telerobotic setup consisting of a magnetic field generator and a mechanical advancer was placed with a silicone vascular phantom in an interventional suite in Switzerland and connected by wireless internet to an operator console in Arizona. From the operator console, the neurosurgeon navigated a guidewire and aspiration catheter to simulated middle cerebral artery (MCA) (n = 10) and basilar artery (n = 10) clots in consecutive timed procedural trials in evaluation of system feasibility and operator learning curve. RESULTS: From over 5700 miles away, the neurosurgeon navigated an aspiration catheter to 10 MCA and 10 basilar artery simulated large vessel occlusions. Clot aspiration was attempted in 4 trials and successful in each. Endovascular navigational time over 10 procedural trials to the M1 segment of the MCA and 10 trials to the basilar artery were completed on average in 114 seconds (SD 44.4 seconds) and 134 seconds (SD 65.8 seconds), respectively. Sufficient operator mastery was demonstrated in 20 procedural iterations with an average 77% reduction in navigational time from aortic arch initial to final trials. CONCLUSION: To our knowledge, we present the first intercontinental aspiration thrombectomy in the preclinical setting in comparable time to the clinical practice and demonstrate the early potential of telerobotic navigation. A lack of haptic feedback did not pose a hindrance, and the potential for intuitive operation offers to drive future research and adoption of this telesurgery system.

Abstract Background The results of a previous phase IIa trial suggested efficacy of the anti-C5a compound vilobelimab in a small number of patients with severe hidradenitis suppurativa (HS) refractory to adalimumab treatment. Objectives To study the efficacy of vilobelimab in a larger-scale randomized phase IIb trial (SHINE) of patients with moderate-to-severe HS. Methods In total, 177 patients with moderate-to-severe HS were treated either with placebo or one of four doses of vilobelimab, a monoclonal antibody that targets the complement split product C5a. Hidradenitis Suppurativa Clinical Response (HiSCR) at 16 weeks was the primary endpoint. Those who achieved HiSCR switched to open-label low-dose vilobelimab; those who did not were switched to medium-dose vilobelimab. The trial was registered with the EU Clinical Trials Register (EudraCT number 2017-004501-40) and ClinicalTrials.gov (NCT03487276). Results The study did not meet the primary endpoint, perhaps due, in part, to an unexpectedly high HiSCR placebo response rate of 47.1%. HS flares decreased and post hoc analysis showed that high-dose vilobelimab significantly decreased the median draining tunnel counts and IHS4 score by 63%. Following the switch to medium-dose vilobelimab at week 16, 45.5% of those who did not respond to treatment achieved HiSCR at week 40. Conclusions Compared with placebo, vilobelimab treatment did not result in significant HiSCR improvements in patients with moderate-to-severe HS. Post hoc analysis revealed significant effects for the highest tested dose on draining tunnel reduction and IHS4 score, which captures reductions in draining tunnels. These findings warrant further investigation.

AbstractAbstract Background Central nervous system (CNS) tumors are a significant cause of morbidity and mortality in Sub-Saharan Africa (SSA). This project aimed to assess and map out the current neuro-oncology capacity in SSA, brain tumor registries, and biobanks. Methods This cross-sectional study utilized an online survey to gather data from healthcare professionals involved in CNS tumor care across SSA through the Society for Neuro-Oncology SSA (SNOSSA). The survey captured information on the availability of neuro-oncology practitioners, neuropathology, molecular diagnostics, cancer registries, and biobanking. Results A total of 145 respondents representing 70 healthcare institutions across 22 countries participated. Of the 70 institutions, specialties included neurosurgery (89%, 62/70), anatomic pathology (74%, 52/70), and medical oncology (71%, 50/70). For radiologic evaluation, 64% (45/70) of responding institutions reported having both CT and MRI. Access to molecular testing through immunohistochemistry or next-generation sequencing was available in 46% (32/70) of responding institutions. Multidisciplinary tumor boards were available for CNS cases in 86% (60/70) of responding institutions. Brain tumor-specific registries were available in 29% (20/70) of responding institutions, and 10% (7/70) maintained brain tumor biorepositories. Conclusion This study demonstrates that SSA has substantial potential in neuro-oncology care practice capacity and facilities. The most significant gaps were in neuropathology and molecular testing, which makes widespread implementation of the WHO 2021 diagnosis challenging. Understanding the prevalence of CNS tumor subtypes in SSA is difficult due to the low number of brain tumor registries and biobanks.

Abstract Background The term “incomplete microscopic colitis” (MCi) has been suggested to define patients with chronic watery diarrhea not fulfilling the complete histologic criteria for MC. There are inconsistent data on the epidemiology of MCi and the optimal management of these patients. Methods A systematic search of randomized control trials (RCTs) and observational studies of adults with biopsy-proven MCi (incomplete lymphocytic colitis and collagenous colitis) was conducted using Cochrane, Medline, Scopus, and Embase from inception to May 6, 2025. Data were extracted on (1) incidence and prevalence of MCi, (2) patient features and risk factors, (3) clinical response with treatment, and (4) relapse after treatment cessation. Data were pooled using the random-effects model to calculate weighted pooled estimates and 95% confidence intervals (CIs). Results Of 136 potentially relevant publications identified, 49 passed abstract screening, and 17 studies (1 RCT and 16 observational) were included, with a total of 1370 patients with MCi (median age of 62 years and 69.6% women). The incidence rate of MCi ranged from 0.96 to 5.0 cases per 100 000 person-years. The pooled proportion of concurrent autoimmune disease with MCi was 18% (95% confidence interval [CI], 0.07-0.28; I2 = 95%), and 46% (95% CI, 0.28-0.64; I2 = 95%) were on medications associated with microscopic colitis (MC). The pooled clinical remission rate with any induction therapy was 78% (95% CI, 0.68-0.89; I2 = 81%) and 85% (95% CI, 0.72-0.98; I2 = 88%) with budesonide. Conclusions Patients with MCi share similar characteristics with full MC including demographics, risk factors, and response to therapy, indicating that the histologic criteria for MC should potentially be broadened.

Abstract Background Few studies have assessed the burden of chronic medical conditions in adolescent and young adult (AYA) cancer survivors. This study estimated the risk of these conditions among AYA survivors compared to a matched cohort without cancer. Methods This retrospective cohort study included 2‐year survivors ( n = 14,917) of 11 common AYA (15–39 years) cancers diagnosed at the integrated health care organizations of Kaiser Permanente (KP) Southern and Northern California during 2006–2020. A comparison cohort ( n = 149,164) without cancer (matched 10:1 by age, sex, calendar year, and KP site) was included. Cumulative incidence (CMI) accounting for death as a competing risk was calculated. Poisson regression estimated the incidence rate ratio (IRR) of each condition in cancer survivors versus the matched cohort, adjusting for age, sex, and race/ethnicity. Results The 5‐year CMI was highest for thyroid (17.4%), respiratory (6.6%), cardiovascular (5.0%), and liver (4.8%) diseases. At 10 years, the CMI of any condition was 39% in survivors versus 26% in the matched cohort. Survivors had a 2‐fold increased risk of being diagnosed with any medical condition (IRR, 2.0; 95% confidence interval [CI], 1.9–2.0) as well as two or more conditions (IRR, 2.3; 95% CI, 2.2–2.5). Risk was highest among survivors of hematologic cancers and those diagnosed with distant stage disease. Elevated risks were observed within all sociodemographic groups of this insured population. Conclusion AYAs with cancer had a higher risk of chronic medical conditions compared to those without cancer. Long‐term surveillance, risk mitigation through lifestyle modifications and effective disease management are crucial to reduce premature mortality.
