Abstract
BACKGROUND & RATIONALE In prior work using non-speech stimuli, children with hearing loss show impaired perception of binaural cues and no significant change in cortical responses to bilateral versus unilateral stimulation. Aims of the present study were to: 1) identify bilateral responses to envelope and spectral components of a speech syllable using the frequency-following response (FFR), 2) determine if abnormalities in the bilateral FFR occur in children with hearing loss, and 3) assess functional consequences of abnormal bilateral FFR responses on perception of binaural timing cues. METHODS A single-syllable speech stimulus (/dα/) was presented to each ear individually and bilaterally. Participants were 9 children with normal hearing (MAge = 12.1 ± 2.5 years) and 6 children with bilateral hearing loss who were experienced bilateral hearing aid users (MAge = 14.0 ± 2.6 years). FFR temporal and spectral peak amplitudes were compared between listening conditions and groups using linear mixed model regression analyses. Behavioral sensitivity to binaural cues were measured by lateralization responses as coming from the right or left side of the head. RESULTS Both temporal and spectral peaks in FFR responses increased in amplitude in the bilateral compared to unilateral listening conditions in children with normal hearing. These measures of "bilateral advantage" were reduced in the group of children with bilateral hearing loss and associated with decreased sensitivity to interaural timing differences. CONCLUSION This study is the first to show that bilateral responses in both temporal and spectral domains can be measured in children using the FFR and is altered in children with hearing loss with consequences to binaural hearing.

Abstract
PURPOSE The impact of age on optimal management of glioblastoma remains unclear. A recent combined analysis of two randomised trials, GEINO14-01 and EX-TEM, found no benefit from extending post-radiation temozolomide in newly diagnosed glioblastoma. Here, we explore the impact of age. METHODS Relevant intergroup statistics were used to identify differences in tumour, treatment and outcome characteristics based on age with elderly patients (EP) defined as age 65 years and over. Survival was estimated using the Kaplan Meier method. RESULTS Of the combined 205 patients, 57 (28%) were EP. Of these, 95% were ECOG 0-1 and 65% underwent macroscopic resection compared with 97% and 61% of younger patients (YP) respectively. There were numerically less MGMT-methylated (56% vs. 63%, p = 0.4) and IDH-mutated (4% vs. 13%, p = 0.1) tumours in EP vs. YP. Following surgery, EP were more likely to receive short course chemoradiation (17.5% vs. 6%, p = 0.017). At recurrence, EP tended to receive or best supportive care (28.3% vs. 15.4%, p = 0.09) or non-surgical options (96.2% vs. 84.6%, p = 0.06), but were less likely to receive bevacizumab (23.1% vs. 49.5%, p < 0.01). Median PFS was similar at 9.3months in EP and 8.5months in YP, with similar median OS at 20months. CONCLUSION In this trial population of predominantly fit EP, survival was similar to YP despite a proportion receiving less aggressive therapy at diagnosis and recurrence. Advancing age does not appear to be an adverse prognostic factor for glioblastoma when patients are fit for treatment, and a less aggressive approach in selected patients may not compromise outcomes.

Abstract
PURPOSE The optimal duration of post-radiation temozolomide in newly diagnosed glioblastoma remains unclear, with no published phase III randomised trials. Standard-of-care stipulates 6 months. However, in routine care, it is often extended to 12 months, despite lacking robust supporting data. METHODS GEINO14-01 (Spain) and EX-TEM (Australia) studies enrolled glioblastoma patients without progression at the end of 6 months post-radiation temozolomide. Participants were randomised 1:1 to six additional months of temozolomide or observation. Primary endpoint was 6-month progression free survival from date of randomisation (6mPFS). Secondary endpoints included overall survival (OS) and toxicity. 204 patients were required to detect an improvement in 6mPFS from 50 to 60% (80% power). Neither study recruited sufficient patients. We performed a combined analysis of individual patient data. RESULTS 205 patients were recruited: 159 in GEINO14-01 (2014-2018) and 46 in EX-TEM (2019-2022). Median follow-up was 20.0 and 14.5 months. Baseline characteristics were balanced. There was no significant improvement in 6mPFS (57.2% vs 64.0%, OR0.75, p = 0.4), nor across any subgroups, including MGMT methylated; PFS (HR0.92, p = 0.59, median 7.8 vs 9.7 months); or OS (HR1.03, p = 0.87, median 20.1 vs 19.4 months). During treatment extension, 64% experienced any grade adverse event, mainly fatigue and gastrointestinal (both 54%). Only a minority required treatment changes: 4.5% dose delay, 7.5% dose reduction, 1.5% temozolomide discontinuation. CONCLUSION For glioblastoma patients, extending post-radiation temozolomide from 6 to 12 months is well tolerated but does not improve 6mPFS. We could not identify any subset that benefitted from extended treatment. Six months should remain standard-of-care.

Comparative genomic analysis of Fischer F344 rat livers exposed for 90 days to 3-methylfuran or its parental compound furan. Food Chem Toxicol 2024; 184:114426. [PMID: 38160780 DOI: 10.1016/j.fct.2023.114426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 12/22/2023] [Accepted: 12/23/2023] [Indexed: 01/03/2024]
Abstract
Furan is a naturally forming compound found in heat-processed foods such as coffee, canned meats, and jarred baby food. It is concurrently found with analogues including 2-methylfuran (2-MF) and 3-methylfuran (3-MF), and toxicity studies demonstrate all are potent liver toxins. Toxicity studies found 3-MF is more toxic than either furan, or 2-MF. The present analysis assesses the transcriptional response in liver samples taken from male Fischer (F344) rats exposed to furan or 3-MF from 0 to 2.0 and 0-1.0 mg/kg bw/day, respectively, for 90 days. Transcriptional analyses found decreased liver function and fatty acid metabolism are common responses to both furan and 3-MF exposure. Furan liver injury promotes a ductular reaction through Hippo and TGFB signalling, which combined with increased immune response results in ameliorating perturbed bile acid homeostasis in treated rats. Failure to activate these pathways in 3-MF exposed rats and decreased p53 activity leads to cholestasis, and increased toxicity. Finally, BMD analysis indicate many of the most sensitive pathways affected by furan and 3-MF exposure relate to metabolism - malate dehydrogenase and glucose metabolism with BMDLs of 0.03 and 0.01 mg/kg bw/day for furan and 3-MF exposure, respectively, which agrees with BMDLs previously reported for apical and microarray data.

Abstract
Planets with radii between that of the Earth and Neptune (hereafter referred to as 'sub-Neptunes') are found in close-in orbits around more than half of all Sun-like stars1,2. However, their composition, formation and evolution remain poorly understood3. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for initial conditions and environment. Those in resonance (with their orbital periods related by a ratio of small integers) are particularly valuable because they imply a system architecture practically unchanged since its birth. Here we present the observations of six transiting planets around the bright nearby star HD 110067. We find that the planets follow a chain of resonant orbits. A dynamical study of the innermost planet triplet allowed the prediction and later confirmation of the orbits of the rest of the planets in the system. The six planets are found to be sub-Neptunes with radii ranging from 1.94R⊕ to 2.85R⊕. Three of the planets have measured masses, yielding low bulk densities that suggest the presence of large hydrogen-dominated atmospheres.

Abstract
This article summarises expert discussion on the management of patients with hepatocellular carcinoma (HCC), which took place during the 24th World Gastrointestinal Cancer Congress (WGICC) in Barcelona, July 2022. A multidisciplinary approach is mandatory to ensure an optimal diagnosis and staging of HCC, planning of curative and therapeutic options, including surgical, embolisation, ablative strategies, or systemic therapy. Furthermore, in many patients with HCC, underlying liver cirrhosis represents a challenge and influences the therapeutic options.

Abstract
Background Live biotherapeutic products (LBPs) offer a more rationalized and multitargeted approach to treating gastrointestinal diseases. BioColoniz and BioPersist are two LBPs derived from the parental strains L. reuteri and E. coli Nissle 1917 (EcN), respectively. The parental strains are known to offer some benefit in preventing relapses in IBD patients however the results are heterogeneous. To overcome this, the parental strains were approached as LBPs by introducing traits to thrive under the inflammatory conditions of the colon. Therefore, our aim is to characterize the role of these LBPs in IBD. Purpose To evaluate the therapeutic effect of the LBPs BioColoniz and BioPersist in an acute model of colitis. Method Female C57Bl/6 mice were treated with BioColoniz or BioPersist via oral gavage for three consecutive days prior to DSS challenge. Then mice were exposed to 3.5% DSS via drinking water for seven days. As controls, we also included mice treated with vehicle or the parental strains L. reuteri or EcN. In order to compare the effect of LBPs in the onset of acute colitis to current maintenance therapies for UC, we also exposed another group of mice to DSS and simultaneously administer 5-ASA. Mice were monitored daily for signs of disease and at the end of the experiment, colon tissue was collected for histopathological and molecular analysis. Result(s) The administration of BioColoniz and BioPersist delayed and decreased the colitic phenotype of mice exposed to DSS. Differences in signs of disease, such as diarrhea and weight loss, were evident by day 4 for vehicle or 5-ASA groups, whereas mice in the LBPs groups were still gaining weight. When analyzing the histopathological changes, mice in the LBPs groups presented lower scores when compared to the vehicle and 5-ASA groups. Specifically, mice treated early with BioColoniz or BioPersist presented a more preserved mucosal architecture with visible crypts. Although 5-ASA-treated mice still had vestiges of crypts, the damage in the mucosal architecture was more severe, similar to the observed in mice treated with the parental strains EcN and L. reuteri. We also looked at the expression of proinflammatory cytokines, finding an increase in TNFα, IFNγ, and IL-17a in mice treated with 5-ASA but not in mice treated with LBPs. However, the expression of protective factors such as mucin Muc2 or the antimicrobial peptide Reg3γ was similarly high in 5-ASA and LBP-treated mice when compared to vehicle or parental strains groups, suggesting some therapeutic commonalities between 5-ASA and our LBPs. Conclusion(s) The early administration of the LBPs BioColoniz and BioPersist protect mice from severe acute colitis, being more protective than 5-ASA. Since some differences and similarities were observed between the LBPs- and 5-ASA-treated mice, such as crypt preservation versus increased expression of some protective factors, the next step will aim to identify which mechanisms are specifically triggered by the LBPs.

Abstract
Abstract
Background
Our knowledge of changes in vegetation size throughout the course of infective endocarditis (IE) and the impact of persistent vegetations on mortality or embolization after completed antibiotic treatment is sparse. No study has previously investigated the prevalence or clinical impact of persistent vegetations on transthoracic echocardiography (TTE) at 6-months follow-up after ended IE treatment.
Purpose
To investigate the association between persistent vegetations at the 6-months TTE after treatment for IE and long-term prognosis as assessed in the POET trial.
Methods
The POET trial was a nationwide, multicenter RCT, randomizing 400 patients to either partial oral or intravenous (IV) antibiotic treatment of left-sided IE, after initial stabilization of infection using conventional IV therapy.
A persistent vegetation was defined as a vegetation seen on 6-months follow-up TTE (4–7 months) after ended antibiotic treatment for IE. In the POET trial, primary outcome was defined as 1) all-cause mortality, 2) unplanned cardiac surgery, 3) embolic events or 4) relapse of bacteremia, in the 5-year follow-up period. Patients without TTE due to death or lack of available TTE were excluded.
Results
Out of 400 patients, 20 were excluded due to death during 6-months follow-up, and 201 were excluded due to unavailable TTE, leaving 179 TTEs for analysis.
At 6-months follow-up, a persistent vegetation was seen in 30 patients (16.7%, 21 males (70%), mean age 69.6 years (SD 7.7)) (Table 1). Seventeen patients (56.7%) had a persistent vegetation on the aortic valve and 13 patients (43.3%) on the mitral valve. More patients without a persistent vegetation had undergone initial surgical treatment of IE than those with a vegetation (57.7 vs 23.3%, p=0.001). In all surgically treated patients with persistent vegetation at 6-months follow-up, the vegetation was found on another valve than the operated valve.
The composite primary outcome from 6-months follow-up and until 5-year follow-up occurred in 8 patients (26.7%) with a persistent vegetation, compared to 38 patients (25.5%) (p=1.00) without. (Table 2) In patients randomized for peroral treatment, no significant difference in prevalence of persistent vegetation was found (15 patients (50%) with persistent vegetations vs. 74 patients (49.7%) without, p=1.00).
Conclusion
The occurrence of persistent vegetations at 6 months follow-up was 16.7%. There was no association between persistent vegetations at 6-months follow-up and the occurrence of the primary outcome after 5 years follow-up, suggesting that the risk associated with residual vegetations after end of antibiotic treatment is negligible after 6-months.

Abstract
This pilot study assessed the feasibility and potential effectiveness of a single-session workshop in modifying parental beliefs/knowledge about attention-deficit/hyperactivity disorder (ADHD) in children and impact on treatment acceptance/utilization. Concerns raised by school professionals about lack of treatment follow-through after ADHD diagnosis and parental misinformation about medication usage catalyzed this project. A single-group pre-post quasi-experimental design was used. Sixty-eight parents completed ADHD knowledge/belief scales and stress inventories, and pre-ADHD and post-ADHD information workshop. Follow-up calls were made after the workshop to assess treatment utilization. Parents/caregivers experienced significant knowledge and belief changes regarding medication efficacy, willingness to accept physician treatment recommendations, and rejection of non-empirically based treatments. Follow-up data showed that 41% of contacted participants met with physicians to discuss medication utilization and behavioral treatments. Brief, one-session psycho-educational workshops were feasible and impacted parental beliefs and behaviors regarding scientifically supported interventions for ADHD.

Abstract
Alcohol misuse affects 15 million people in the United States. Compared to White men, Latino men have disproportionately higher rates of both alcohol misuse and negative alcohol-related consequences (e.g. drunk driving, liver disease, alcohol dependence, HIV/AIDS). This cross sectional study examined how cultural stressors [immigration stress and negative context of reception (NCR)] coupled with traditional Latino male gender norms (machismo and caballerismo) influences alcohol use severity (AUS) among adult Latino immigrant men. Data for the present study was collected between 2017 and 2018 from 279 Cuban, Central American, and South American adult Latino men who immigrated to the US approximately 10 years prior. Results from hierarchical multiple regression analysis revealed higher levels of perceived NCR (β = 0.15, p = .01), and machismo (β = 0.16, p = .02) were associated with greater AUS. Significant interaction effects were found between both cultural stressors and machismo [immigration stress x machismo (β = 0.22, p < .001); NCR x machismo (β = 0.22, p < .001)] whereby higher levels of machismo strengthened the association between cultural stress and AUS. Findings from the present study can inform culturally appropriate interventions aimed at mitigating alcohol use among Latino immigrant men.

Abstract
Bone infection has received increasing attention in recent years as one of the main outstanding clinical problems in orthopaedic-trauma surgery that has not been successfully addressed. In fact, infection may develop across a spectrum of patient types regardless of the level of perioperative management, including antibiotic prophylaxis. Some of the main unknown factors that may be involved, and the main targets for future intervention, include more accurate and less invasive diagnostic options, more thorough and accurate debridement protocols, and more potent and targeted antimicrobials. The underlying biology dominates the clinical management of bone infections, with features such as biofilm formation, osteolysis and vascularisation being particularly influential. Based on the persistence of this problem, an improved understanding of the basic biology is deemed necessary to enable innovation in the field. Furthermore, from the clinical side, better evidence, documentation and outreach will be required to translate these innovations to the patient. This review presents the findings and progress of the AO Trauma Clinical Priority Program on the topic of bone infection.

Abstract
Abstract
Introduction
Transthyretin amyloid cardiomyopathy (ATTR-CM) is being increasingly recognized due to recent advances in non-invasive imaging notably bone scintigraphy and newer effective therapies - particularly tafamidis, which was shown to improve survival and decrease heart failure hospitalizations in the ATTR-ACT trial. Earlier tafamidis use appeared to be more beneficial, as reflected by NYHA class I and II patients being associated with lower mortality and hospitalizations compared to NYHA class III. Increased awareness will likely lead to an increasing number of ATTR-CM patients being diagnosed with concerns regarding applicability of ATTR-ACT criteria on these patients.
Purpose
To investigate ATTR-CM phenotypic presentation trends based on initial clinical, biomarkers and transthoracic echocardiographic (TTE) data.
Methods
From 2005–2020, 116 ATTR-CM patients were seen at our amyloidosis center, who were stratified into 3 time periods based on the date of diagnosis: Early (21 patients, pre-2016), Mid (46 patients, 2016–2018), and Recent (49 patients, 2018–2020). ATTR-CM diagnosis was established based on the standard criteria of confirmed ATTR variant + typical TTE features; histological confirmation endomyocardial biopsy; or typical diffuse cardiac tracer uptake on bone scintigraphy while ruling out light chain amyloidosis. With less typical imaging, cardiac MRI typically served as a confirmatory test prior to pursuing histological confirmation. Demographics, cardiac biomarkers, diagnostic method used, and TTE variables that raise the suspicion of ATTR-CM were compared across time periods using one-way ANOVA test and Fischer's exact test.
Results
There was a significant change in the predominant method of diagnosis with the majority of patients in the Early time period diagnosed by endomyocardial biopsy, whereas in the Recent time period the majority of patients were diagnosed via pyrophosphate scintigraphy (Figure). Despite increasing number of patients being diagnosed, the clinical phenotype at diagnosis did not change significantly with similar proportion of patients NYHA class I/II, median daily diuretic dose, biomarkers, having at least one heart failure hospitalization prior to diagnosis, and similar TTE phenotype (Table). Only the age at diagnosis significantly increased across time periods. Women represented the minority of patients across all time periods.
Conclusion
Despite the increased awareness of ATTR-CM, there have been no major changes in the clinical, cardiac biomarker, or TTE phenotype on presentation in patients referred to our center for suspicion or a diagnosis of ATTR-CM. Our findings challenge the assumption that patients with ATTR-CM are being identified earlier with milder phenotypes. Women with ATTR-CM likely remain largely undiagnosed in our community. Continued education and knowledge dissemination are essential to identify ATTR-CM patients earlier to achieve better outcomes in this population.

Abstract
INTRODUCTION MEK inhibition is a potential therapeutic strategy in non-small cell lung cancer (NSCLC). This phase I study evaluates the MEK inhibitor binimetinib plus carboplatin and pemetrexed in stage IV non-squamous NSCLC patients (NCT02185690). METHODS A standard 3 + 3 dose-escalation design was used. Binimetinib 30 mg BID (dose level 1 [DL1]) or 45 mg BID (dose level 2 [DL2]) was given with standard doses of carboplatin and pemetrexed using an intermittent dosing schedule. The primary outcome was determination of the recommended phase II dose (RP2D) and safety of binimetinib. Secondary outcomes included efficacy, pharmacokinetics, and an exploratory analysis of response based on mutation subtype. RESULTS Thirteen patients (6 DL1, 7 DL2) were enrolled: 7 KRAS, 5 EGFR, and 1 NRAS mutation. The RP2D was binimetinib 30 mg BID. Eight patients (61.5%) had grade 3/4 adverse events, with dose limiting toxicities in 2 patients at DL2. Twelve patients were evaluated for response, with an investigator-assessed objective response rate (ORR) of 50% (95% CI 21.1%-78.9%; ORR 33.3% by independent-review, IR), and disease control rate 83.3% (95% CI 51.6%-97.9%). Median progression free survival (PFS) was 4.5 months (95% CI 2.6 months-NA), with a 6-month and 12-month PFS rate of 38.5% (95% CI 19.3%-76.5%) and 25.6% (95% CI 8.9%-73.6%), respectively. In an exploratory analysis, KRAS/NRAS-mutated patients had an ORR of 62.5% (ORR 37.5% by IR) vs. 25% in KRAS/NRAS wild-type patients. In MAP2K1-mutated patients, the ORR was 42.8%. CONCLUSION The addition of binimetinib to carboplatin and pemetrexed appears to have manageable toxicity with evidence of activity in advanced non-squamous NSCLC.
