All-cause and cause-specific mortality in patients with chronic hepatitis B and concurrent steatotic liver disease.

Background & Aims: Steatotic liver disease (SLD) is prevalent among patients with chronic hepatitis B (CHB). However, the effects of metabolic dysfunction-associated SLD (MASLD) on the long-term survival of such patients remain unknown. Accordingly, this study investigated the mortality risks in patients with CHB and concurrent SLD.

Acute Effects of High-Intensity Resistance Exercise on Recognition of Relational Memory, Lactate, and Serum and Plasma Brain-Derived Neurotrophic Factor.

Baumgartner, NW, Belbis, MD, Kargl, C, Holmes, MJ, Gavin, TP, Hirai, DM, and Kao, S-C. Acute effects of high-intensity resistance exercise on recognition of relational memory, lactate, and serum and plasma brain-derived neurotrophic factor. J Strength Cond Res 38(11): 1867-1878, 2024-Acute aerobic exercise improves memory, but this phenomenon is understudied in response to resistance exercise (RE) despite evidence that RE-induced increases in lactate and brain-derived neurotrophic factor (BDNF) play mechanistic roles in memory performance.

Efficacy evaluation of a bivalent subunit vaccine against classical swine fever virus and porcine circovirus type 2.

Classical swine fever virus (CSFV) and porcine circovirus type 2 (PCV2) are two of the most devastating and economically significant pathogens affecting pig populations worldwide. Administration of a combination of vaccines against swine pathogens has been demonstrated to be as efficacious as the administration of single vaccines. In this study, we developed and tested a novel bivalent subunit vaccine against CSFV and PCV2.

Change in Caregiver Health-Related Quality of Life From Before to Early After Surgery: SUSTAIN-IT Study.

Background: Information about health-related quality of life (HRQOL) among caregivers of older patients with heart failure who receive heart transplantation (HT) and mechanical circulatory support (MCS) is sparse. We describe differences and factors associated with change in HRQOL before and early post-surgery among caregivers of older heart failure patients who underwent 3 surgical therapies: HT with pretransplant MCS (HT MCS), HT without pretransplant MCS (HT non-MCS), and long-term MCS.

Methods: Caregivers of older patients (60-80 years) from 13 US sites completed the EQ-5D-3 L visual analog scale (0 [worst]-100 [best] imaginable health state) and dimensions before and 3 and 6 months post-surgery.

Pilot-scale production of inactivated monoglycosylated split HN influenza virus vaccine provides cross-strain protection against influenza viruses.

Influenza epidemics and pandemics caused by newly emerging virus strains highlight an urgent need to develop a universal vaccine against viruses. Previously, a monoglycosylated X-181 vaccine demonstrated that the HA possessing a single N-acetylglucosamine at each N-glycosylation site is superior to confer broader protection in mice than conventional vaccines. However, the greatest challenge in conducting clinical trials is the need to develop robust manufacturing processes capable of producing vaccines at the pilot scale with the desired stability, potency, and efficacy.

The clinical effects of inclisiran, a first-in-class LDL-C lowering siRNA therapy, on the LDL-C levels in Chinese patients with hypercholesterolemia.

Background: Inclisiran is a novel siRNA therapy that inhibits the synthesis of proprotein convertase subtilisin-kexin type 9 (PCSK9) by targeting the PCSK9 mRNA, consequently, decreases low-density lipoprotein cholesterol (LDL-C).

Objective: To assess the safety, PK and LDL-C lowering effects of inclisiran in the Chinese patients with elevated LDL-C despite treatment with maximally tolerated LDL-C lowering therapies.

Methods: Forty Chinese patients with hypercholesterolemia (LDL-C ≥100 mg/dL) who were on maximally tolerated statin were randomized to receive a single dose of either inclisiran sodium 100 or 300mg s.

Mutations in α-synuclein, TDP-43 and tau prolong protein half-life through diminished degradation by lysosomal proteases.

Background: Autosomal dominant mutations in α-synuclein, TDP-43 and tau are thought to predispose to neurodegeneration by enhancing protein aggregation. While a subset of α-synuclein, TDP-43 and tau mutations has been shown to increase the structural propensity of these proteins toward self-association, rates of aggregation are also highly dependent on protein steady state concentrations, which are in large part regulated by their rates of lysosomal degradation. Previous studies have shown that lysosomal proteases operate precisely and not indiscriminately, cleaving their substrates at very specific linear amino acid sequences.

Modified preoperative score to predict disease-free survival for hepatocellular carcinoma patients with surgical resections.

Background: No prognostic models specific to hepatocellular carcinoma patients receiving surgical resection have been considered strong and convincing enough for survival prediction thus far, and there are no models including only preoperative predictors. We derived a nomogram to predict disease-free survival in a previous study.

Aim: To simplify our score and compare research outcomes among other scoring systems.

Metabolic dysfunction-associated fatty liver disease and chronic hepatitis B.

Fatty liver disease and chronic hepatitis B (CHB) are the major causes for chronic liver diseases and the associated adverse outcomes. Concurrent hepatic steatosis has been found to inversely correlate with hepatitis B virus (HBV) activity both in vivo and in vitro; however, the subsequent effects on the prognosis, including advanced fibrosis and hepatocellular carcinoma (HCC) development, remain diverse and inconclusive. Although the newly-proposed criteria of metabolic dysfunction-associated fatty liver disease (MAFLD) help raise disease awareness and facilitate timely diagnosis and management, its clinical impact on patients with CHB, especially after taking the metabolic dysfunction into consideration, is largely unknown and warrants comprehensive investigations to improve the management of CHB population.

Composition, Morphology, and Interface Engineering of 3D Cauliflower-Like Porous Carbon-Wrapped Metal Chalcogenides as Advanced Electrocatalysts for Quantum Dot-Sensitized Solar Cells.

Designing a low-cost, highly efficient, and stable electrocatalyst that can synergistically speed up the reduction of polysulfide electrolytes while operative for long periods in the open air is critical for the practical application of quantum dot-sensitized solar cells (QDSSCs), but it remains a challenging task. Herein, a simple, straightforward, and two-step nanocomposite engineering approach that simultaneously combines metallic copper chalcogenides (MC) either Cu S or Cu Se with S, N dual-doped carbon (SNC) sources for devising high-quality counter electrode (CE) film are reported. First, the hierarchically assembled MC nanostructures are obtained using microwave-assisted synthesis.

Edoxaban Versus Dual Antiplatelet Therapy for Leaflet Thrombosis and Cerebral Thromboembolism After TAVR: The ADAPT-TAVR Randomized Clinical Trial.

Background: It is unknown whether the direct oral anticoagulant edoxaban can reduce leaflet thrombosis and the accompanying cerebral thromboembolic risk after transcatheter aortic valve replacement. In addition, the causal relationship of subclinical leaflet thrombosis with cerebral thromboembolism and neurological or neurocognitive dysfunction remains unclear.

Methods: We conducted a multicenter, open-label randomized trial comparing edoxaban with dual antiplatelet therapy (aspirin plus clopidogrel) in patients who had undergone successful transcatheter aortic valve replacement and did not have an indication for anticoagulation.

Stimulation of the hepatoportal nerve plexus with focused ultrasound restores glucose homoeostasis in diabetic mice, rats and swine.

Peripheral neurons that sense glucose relay signals of glucose availability to integrative clusters of neurons in the brain. However, the roles of such signalling pathways in the maintenance of glucose homoeostasis and their contribution to disease are unknown. Here we show that the selective activation of the nerve plexus of the hepatic portal system via peripheral focused ultrasound stimulation (pFUS) improves glucose homoeostasis in mice and rats with insulin-resistant diabetes and in swine subject to hyperinsulinemic-euglycaemic clamps.

Dental cementum virtual histology of Neanderthal teeth from Krapina (Croatia, 130-120 kyr): an informed estimate of age, sex and adult stressors.

The evolution of modern human reproductive scheduling is an aspect of our life history that remains vastly uncomprehended. The present work aims to address this gap by validating a non-destructive cutting-edge methodology to infer adult life-history events on modern teeth with known life history and then applying it to fossil specimens. We use phase-contrast synchrotron X-ray microtomography to visualize the dental cementum of 21 specimens: nine contemporary humans; 10 Neanderthals from Krapina (Croatia, 130-120 kyr); one Neolithic from Ajmana (Serbia); and one Mesolithic from Vlasac (Serbia).

Using Deep Neural Networks for Predicting Age and Sex in Healthy Adult Chest Radiographs.

Background: The performance of chest radiography-based age and sex prediction has not been well validated. We used a deep learning model to predict the age and sex of healthy adults based on chest radiographs (CXRs).

Methods: In this retrospective study, 66,643 CXRs of 47,060 healthy adults were used for model training and testing.

BB-301: a silence and replace AAV-based vector for the treatment of oculopharyngeal muscular dystrophy.

Oculopharyngeal muscular dystrophy (OPMD) is a rare autosomal dominant disease that results from an alanine expansion in the N-terminal domain of Poly-A Binding Protein Nuclear-1 (PABPN1). We have recently demonstrated that a two-vector gene therapy strategy significantly ameliorated the pathology in a mouse model of OPMD. This approach entailed intramuscular injection of two recombinant adeno-associated viruses (AAVs), one expressing three short hairpin RNAs (shRNAs) to silence both mutant and wild-type PABPN1 and one expressing a codon-optimized version of PABPN1 that is insensitive to RNA interference.

Micromechanical evaluation of cortical bone using in situ XCT indentation and digital volume correlation.

The overall mechanical behaviour of cortical bone is strongly dependant on its microstructure. X-ray computed tomography (XCT) has been widely used to identify the microstructural morphology of cortical tissue (i.e.

A Randomized Trial Comparing Antibiotics with Appendectomy for Appendicitis.

Background: Antibiotic therapy has been proposed as an alternative to surgery for the treatment of appendicitis.

Methods: We conducted a pragmatic, nonblinded, noninferiority, randomized trial comparing antibiotic therapy (10-day course) with appendectomy in patients with appendicitis at 25 U.S.

MR Imaging Correlates for Molecular and Mutational Analyses in Children with Diffuse Intrinsic Pontine Glioma.

Background And Purpose: Recent advances in molecular techniques have characterized distinct subtypes of diffuse intrinsic pontine gliomas. Our aim was the identification of MR imaging correlates of these subtypes.

Materials And Methods: Initial MRIs from subjects with diffuse intrinsic pontine gliomas recruited for a prospective clinical trial before treatment were analyzed.

Attainment of treat-to-target endpoints in SLE patients with high disease activity in the atacicept phase 2b ADDRESS II study.

Objective: Low disease activity (LDA) and remission are emerging treat-to-target (T2T) endpoints in SLE. However, the rates at which these endpoints are met in patients with high disease activity (HDA) are unknown. Atacicept, which targets B lymphocyte stimulator and a proliferation-inducing ligand, improved disease outcomes in SLE patients with HDA (SLEDAI-2K ≥10) at baseline in the phase 2b ADDRESS II study.

Noninvasive sub-organ ultrasound stimulation for targeted neuromodulation.

Tools for noninvasively modulating neural signaling in peripheral organs will advance the study of nerves and their effect on homeostasis and disease. Herein, we demonstrate a noninvasive method to modulate specific signaling pathways within organs using ultrasound (U/S). U/S is first applied to spleen to modulate the cholinergic anti-inflammatory pathway (CAP), and US stimulation is shown to reduce cytokine response to endotoxin to the same levels as implant-based vagus nerve stimulation (VNS).

Autophagy inhibition plays a protective role against 3, 4-methylenedioxymethamphetamine (MDMA)-induced loss of serotonin transporters and depressive-like behaviors in rats.

The 3,4-methylenedioxymethamphetamine (MDMA) is a popular recreational drug, which ultimately leads to serotonergic (5-HT) neurotoxicity and psychiatric disorders. Previous in vitro studies have consistently demonstrated that MDMA provokes autophagic activation, as well as damage of 5-HT axons and nerve fibers. So far, whether autophagy, a well-conserved cellular process that is critical for cell fate, also participates in MDMA-induced neurotoxicity in vivo remains elusive.

How long is too long? A scoping review of health system delays in lung cancer.

Earlier access to lung cancer specialist (LCS) care improves survival, highlighting the need for streamlined patient referral. International guidelines recommend 14-day maximum time intervals from general practitioner (GP) referral to first LCS appointment ("GP-LCS interval"), and diagnosis to treatment ("treatment interval"). We compared time intervals in lung cancer care against timeframe benchmarks, and explored barriers and facilitators to timely care.

Acoustic Radiation Force Impulse US Imaging: Liver Stiffness in Patients with Chronic Hepatitis B with and without Antiviral Therapy.

Purpose To investigate the clinical utility and longitudinal change of acoustic radiation force impulse (ARFI) ultrasonographic (US) imaging in patients with chronic hepatitis B. Materials and Methods A retrospective cohort study of patients with chronic hepatitis B who underwent serial ARFI examinations in a tertiary referral center in Taiwan between 2012 and 2016 was conducted. The clinical information and noninvasive liver stiffness measurement tests (ARFI, Fibrosis-4 index [FIB-4], and FibroScan) were collected.

Sonographic Evaluation of Pediatric Thyroid Nodules.

A thyroid nodule detected clinically or incidentally at medical imaging is a common indication for ultrasonography (US) in the adult population. This scenario is less frequently the case in pediatric patients, and the approach to evaluation of thyroid nodules deserves modification in these patients because of the increased probability of malignancy in children, compared with adults. Evaluating a thyroid nodule with US in a systematic way requires familiarity with a number of features that can be assessed and the terms that the radiologist uses in each category.

Imaging of Skeletal Disorders Caused by Fibroblast Growth Factor Receptor Gene Mutations.

Fibroblast growth factors and fibroblast growth factor receptors (FGFRs) play important roles in human axial and craniofacial skeletal development. FGFR1, FGFR2, and FGFR3 are crucial for both chondrogenesis and osteogenesis. Mutations in the genes encoding FGFRs, types 1-3, are responsible for various skeletal dysplasias and craniosynostosis syndromes.
