Background: There is no consensus scoring system for staging and prognosis in hepatocellular carcinoma (HCC), which is the fourth leading cause of cancer-related mortality worldwide. Commonly used systems include the albumin–bilirubin (ALBI) score, the Barcelona staging classification (Barcelona Clinic Liver Cancer, BCLC), the Model for End-Stage Liver Disease (MELD), and the model to estimate survival in ambulatory HCC patients (MESIAH). Liver secretion of pseudocholinesterase (PCHE) has been linked to liver function but is poorly studied in the natural history of HCC. We evaluated whether serum PCHE level predicts HCC mortality and whether it enhances existing scoring systems. Methods: We conducted a retrospective cohort study of individuals diagnosed with HCC. We collected variables including PCHE level, clinical data used in scoring systems, and time to mortality or liver transplant. We then analyzed the association between these variables and survival using Kaplan–Meier curves, Cox proportional hazards regression models, receiver operating characteristic (ROC) curves, and area under the curve (AUC) calculations. Results: We identified 420 individuals with HCC who were tested for PCHE levels, with a follow-up time of more than 20 years. There was a strong inverse relationship between PCHE level and overall survival, with the lowest quartile having high mortality and poor outcomes. Low PCHE level was associated with hepatitis C virus (HCV) infection, vascular invasion, poor liver function, and a high likelihood of liver transplant. In contrast, the highest quartile was associated with metabolic dysfunction–associated steatotic liver disease (MASLD) as the underlying cause. Compared with validated scoring systems, ALBI, BCLC, MELD 3.0, and MESIAH, the PCHE level was an independent predictor of mortality. PCHE levels could predict 3-month survival as well as or better than the other scoring systems, with an AUC of 0.74. PCHE level could also predict mortality related to hepatectomy. The addition of PCHE level to MESIAH and ALBI scoring systems could further improve the ability to predict overall mortality in HCC. Conclusions: PCHE is a reliable stand-alone biomarker of HCC prognosis. It is an independent predictor of mortality and can improve the accuracy of existing scoring systems. Improved risk stratification could improve outcomes by informing treatment decisions regarding hepatectomy or other interventions.

Key Points This study reveals the temporal development and progression of senescence in an arteriovenous fistula of uremic mice. Senescent genes including p21 increased 7 days after arteriovenous fistula placement, and p16 and phosphorylated p53 cells accumulate between days 14 and 28. Transcriptomic analyses confirm established genes in arteriovenous fistula failure and suggest a collection of novel genes of interest. Background Hemodialysis therapy for ESKD requires suitable vascular access, most commonly the arteriovenous fistula (AVF). Forty percent of AVFs fail within 1 year, leading to morbidity and care costs. Failure mechanisms remain unclear, and current therapies are inadequate. Cellular senescence may be critical in AVF failure, and ESKD itself may accelerate senescence and subsequent vascular dysfunction. Senescence follows AVF placement in rodents with normal kidney function, but the temporal and spatial features in uremic conditions are unknown. This study aimed to characterize AVF changes in uremic mice over time and versus control vessels. Methods Six- to eight-week-old male C57BL6/J mice underwent five/six nephrectomy. Twenty-eight days later, an AVF was created by cuff anastomosis (right carotid artery to the right jugular vein). Transcriptomic analysis was performed 7 days post-AVF, and further samples were collected at 14 and 28 days post-AVF creation for histologic assessment. Results AVF outflow vein morphometry showed reduced neointimal cell density. Whole transcriptomic analysis of outflow versus control veins at 7 days post-AVF placement revealed 1187 upregulated and 3256 downregulated genes. Differentially expressed genes were significantly enriched in two established senescence-related gene sets, SenMayo (a curated panel of approximately 125 genes validated across species to capture senescence and associated proteins) and SenSig (a broader panel assessed to represent fibrotic and stress-induced cell response). Histologically, senescence markers p16, p21, and phospho53 increased between days 14 and 28. Genes common to our dataset, SenMayo, and SenSig were validated with quantitative reverse transcription PCR. Conclusions These data support established markers of AVF failure, such as matrix-metalloproteinases and monocyte chemokines, and identify potential novel modulators of AVF survival that may inform senolytic strategies to improve patency. In summary, this study reveals for the first time the chronologic progression of vascular senescence in the AVF of uremic mice.

Abstract Aims Heart failure (HF) with preserved (HFpEF) and mildly reduced (HFmrEF) ejection fraction are prevalent, yet frequently underdiagnosed syndromes associated with high morbidity and mortality, impaired quality of life, and escalating healthcare expenditures. Although guideline-directed medications like SGLT2 inhibitors have been shown to reduce the risk of hospitalization and cardiovascular death, their use remains limited and substantial residual risk persists. This trial aims to evaluate the safety and performance of a novel left-atrium-to-coronary-sinus shunt (Edwards APTURE transcatheter shunt system) in HFpEF and HFmrEF patients. Methods ALT-FLOW II is a prospective multi-centre, randomized, sham-controlled, double-blinded (patient and assessor) trial. Approximately 100 symptomatic HF patients aged ≥18 years with left ventricular ejection fraction >40% and exercise pulmonary capillary wedge pressure (PCWP) ≥25 mm Hg with a PCWP to right atrial pressure gradient ≥8 mm Hg will be randomized 1:1 to the APTURE shunt vs sham control. Key exclusion criteria include severe HF, significant valvular disease, and more than mild right ventricular dysfunction. The primary endpoints are the safety of the APTURE device at 30 days and change in workload-corrected PCWP normalized to bodyweight at 6 months. Secondary endpoints include changes in patient-reported outcomes, and hemodynamic and echocardiographic parameters through 5 years. The trial will also explore the impact of the device on short-term cardiac remodelling and intra-cardiac flow patterns using multi-modality imaging. Conclusions The ALT-FLOW II trial will evaluate the safety and performance of the APTURE system in symptomatic HFpEF and HFmrEF patients with elevated left atrial pressure.

Introduction Previous studies have demonstrated that C 11 choline positron emission tomography/computed tomography (Choline-PET/CT) can localize abnormal parathyroid glands in the reoperative setting. This study assesses a large volume of patients with primary hyperparathyroidism (1HPT) who underwent Choline-PET/CT to confirm its utility in the setting of negative or equivocal conventional imaging. Methods All patients who underwent Choline-PET/CT for evaluation of 1HPT from July 2017 to July 2024 at a single institution were reviewed. Inclusion criteria were patients who underwent parathyroidectomy and had lab testing to assess for cure (defined as >50% drop from baseline PTH and into normal range, or resolution of hypercalcemia at follow-up). Sensitivity, positive predictive value (PPV), false negative rate (FNR), and accuracy were compared to conventional imaging (neck ultrasound, parathyroid scan, and parathyroid four-dimensional CT (4D-CT)). Subgroup analysis was conducted comparing sensitivity of modalities among index operations and separately in reoperations. Results 84 patients were included for analysis. 61 failed to localize on at least one conventional modality, and 15 failed to localize on all conventional studies. 67 patients (80%) achieved cure, of which 53 were reoperations. Choline-PET/CT outperformed conventional modalities across sensitivity, PPV, FNR, and accuracy. Choline-PET/CT also outperformed conventional modalities when comparing sensitivity in both subgroups. Conclusion C 11 choline-PET/CT is a valuable imaging modality in the reoperative setting and demonstrates utility for index operations. It provides localization when other modalities fail and allows for a high surgical cure rate. Further investigation into its utility as a primary imaging modality is warranted.

Abstract Aims Glucagon-like peptide-1 receptor agonists (GLP-1RA) reduce cardiovascular risk in patients with Type 2 diabetes (T2D) and established atherosclerotic cardiovascular disease and are recommended in guidelines. We evaluated the real-world effectiveness of GLP-1RA therapy on cardiovascular outcomes in patients with T2D after myocardial infarction (MI) or ischaemic stroke and examined trends and disparities. Methods and results Using nationwide Czech registry data (2015–24), we identified patients with incident nonfatal MI or ischaemic stroke and confirmed T2D. GLP-1RA users—initiating therapy within 12 months post-event—were propensity score matched to non-users. The primary outcome was major adverse cardiovascular events (MACE: nonfatal MI, nonfatal stroke, cardiovascular death); secondary outcomes included individual components and all-cause mortality. GLP-1RA therapy was initiated in only ∼2% of MI and stroke survivors with T2D. Among 126 845 MI survivors, 28 206 had T2D; the matched cohort comprised 2271 patients (401 GLP-1RA; median follow-up 35 months). GLP-1RA use was associated with lower risk of MACE (HR 0.7; 95% CI, 0.52–0.93), all-cause (HR 0.61; 95% CI, 0.47–0.80), and cardiovascular death (HR 0.54; 95% CI, 0.36–0.80). Among 177 115 stroke survivors, 73 750 had T2D; the matched cohort comprised 2235 patients (385 GLP-1RA; median follow-up 27 months). GLP-1RA use was associated with lower risk of MACE (HR 0.71; 95% CI, 0.54–0.94), all-cause (HR 0.59; 95% CI, 0.46–0.76), and cardiovascular death (HR 0.55; 95% CI, 0.37–0.81). Conclusion GLP-1RA therapy after MI or stroke in T2D was associated with substantially lower risks of MACE, cardiovascular, and all-cause death in real-world practice. Utilization remained low, particularly among women and older adults, underscoring the need for broader and more equitable implementation in secondary prevention.

Abstract Caregivers for people with neurodegenerative disease (PWNDs) often experience mental and physical health problems, especially when caring for PWNDs who have deficits in emotional functioning. We studied 65 PWNDs and their caregivers both during active caregiving and after caregiving had ended to determine: (a) how caregiver health changes after caregiving ends; and (b) whether PWNDs’ emotional functioning predicts these changes. PWND emotional functioning was assessed in the laboratory by measuring their generation of preparatory physiological activity (e.g., increased heart rate) to an upcoming emotional event (i.e., emotion eliciting films). Caregiver mental and physical health were measured using the Short-Form Health Survey (SF36) during active caregiving and again after caregiving had ended. Results indicated that, overall, caregivers reported increases in mental health, (t(36) = 2.58, p = .014, 95% CI [1.31, 10.93]) but decreases in physical health (t(36) = -2.35, p = .025, 95% CI [-7.26, -0.53]) across the two measurement periods. Using latent change score models, PWNDs’ preparatory physiological response impairments were associated with better caregiver mental health trajectories (β = -0.37, SE = 0.04, p = .003) such that smaller PWND preparatory responses predicted greater improvements in caregiver mental health (β = 9.92, SE = 2.84, p < .001). There was no association with changes in caregiver physical health. Smaller preparatory physiological responses in PWNDs may indicate diminished emotional responding, which is linked with lower caregiver mental health during active caregiving. Once caregiving ends, these caregivers may be most likely to “rebound” and show improvements in mental health.

Abstract As a group, family caregivers of people with dementia (PWDs) have substantially elevated levels of depression and anxiety, compared to same-aged non-caregiving adults. However, there is striking variation in mental health among individual caregivers. Previous research on predictors of the sources of these individual differences has focused on characteristics of individual caregivers and PWDs (rather than on the caregiver-PWD relationship), self-report measures (rather than behavioral measures), and negative emotion (rather than positive emotion). We examined 185 caregiver-PWD dyads who had an unrehearsed 10-minute conversation about an area of conflict in the laboratory. Video recordings were coded for Behavioral Indicators of Positivity Resonance (BIPR), which derives from Positivity Resonance Theory and assesses dyad-level behavioral expressions of positive affect, mutual warmth, and synchrony. Caregivers reported their level of depression, anxiety, and emotional well-being and PWDs underwent a comprehensive neurological and neuropsychological evaluation. Pearson’s correlations revealed that greater dyad-level BIPR was associated with caregivers’ higher emotional well-being (r(181) = .19, p = .008), lower depression (r(179) = -.17, p = .025), and lower anxiety (r(180) = -.15, p = .045). Regression analyses revealed that these associations were still obtained after controlling for caregiver age and sex and PWD dementia severity, cognitive impairment, and neuropsychiatric behavior (emotional well-being ß = .18, p = .012; depression ß = -.15, p = .039; anxiety ß = -.15, p = .044). Future studies should determine whether interventions that increase co-experienced positive emotions among caregiver-PWD dyads help buffer caregivers from adverse mental health consequences.

Objectives Ultrasound‐guided percutaneous needle fenestration (UPNF) and percutaneous needle tenotomy (UPNT) are minimally invasive procedures commonly used to treat chronic tendinopathies. However, these techniques can be painful, potentially limiting patient tolerance, satisfaction, and procedural feasibility. Although local anesthetics (LAs) provide analgesia, their potential inhibitory effects on tenocyte activity and the efficacy of orthobiologics raise concerns regarding their impact on tendon healing. The objectives of this study is to propose a practical, anatomy‐based approach for the use of ultrasound‐guided peripheral nerve blocks (USG‐PNBs) as a strategy to reduce pain and improve patient comfort during UPNF and UPNT, with or without orthobiologic adjuncts. Methods We reviewed commonly affected anatomical sites in chronic tendinopathies and identified corresponding peripheral nerve targets that can be reliably and safely blocked under ultrasound guidance. For each condition, we outline appropriate nerve block techniques, anatomical landmarks, and recommended patient positioning to optimize procedural analgesia. Results A set of targeted USG‐PNBs was defined for commonly treated tendinopathies, including supraspinatus tendinopathy, lateral and medial epicondylitis, gluteus medius and/or minimus tendinopathy, patellar tendinopathy, Achilles tendinopathy, and plantar fasciopathy. Conclusion Ultrasound‐guided peripheral nerve blocks represent a practical and effective approach to manage pain during percutaneous procedures for chronic tendinopathies. By reducing procedural discomfort and avoiding the potential drawbacks of peritendinous LAs, these techniques may enhance patient tolerance, procedural success, and overall clinical outcomes.

Abstract Background Liver surgery carries a high risk of complications due to the complex interplay of patient-related factors, disease characteristics, and liver function. Expertise is essential for healthcare professionals managing hepatobiliary patients. This European consensus provides evidence-based guidance on selected aspects of peri- and postoperative care. Methods A modified Delphi process was used to achieve consensus, with a 70% agreement threshold. The expert panel comprised hepatobiliary surgeons, anaesthetists, hepatologists, a specialist nurse, and a physiotherapist. A systematic literature search was conducted in PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases. Six topics were addressed: thromboprophylaxis; perioperative antibiotics; prehabilitation/nutrition/mobilization; bile leak including bilioenteric anastomosis leaks; post-hepatectomy haemorrhage; and post-hepatectomy liver failure (PHLF). Evidence appraisal and statement development followed Scottish Intercollegiate Guidelines Network methodology. A patient representative reviewed the guideline. Results Searching the literature yielded 204 included publications from an initial 6514. Thirty-two statements were formulated with a median evidence level of 2. Evidence strength varied by topic with noticeably lower evidence levels in complex surgery settings and less prevalent conditions. In some topics, study heterogeneity and specific inclusion criteria resulted in conditional recommendations, despite high-level evidence. Notably, the weakest evidence was found for perioperative thromboprophylaxis and PHLF management. Strong recommendations were formulated for prehabilitation, early postoperative mobilization, and avoidance of routine drain use. Several evidence gaps warranting multicentre studies were identified. Conclusion Optimizing peri- and postoperative care after liver resection remains challenging. Standardizing key practices and addressing evidence gaps through collaborative research are vital to improve outcomes.
