Rationale & Objective: Sharing Patient's Illness Representations to Increase Trust (SPIRIT) is an evidence-based advance care planning intervention targeting dialysis patients and their surrogate decision-makers. To address SPIRIT's implementation potential, we report on a process evaluation in our recently completed five-state cluster-randomized trial.

Study Design: A descriptive study of implementation within a randomized clinical trial.

Heterologous expression of a recombinant ACE inhibitory peptide LYPVK and its potential antihypertensive action mechanism.

Enzymatic hydrolysis approach is commonly employed for preparation of active peptides, while the limited purity and yield of produced peptides hinder further development of action mechanisms. This study presents the biotechnological approach for the efficient production of recombinant angiotensin converting enzyme (ACE) inhibitory peptide LYPVK and investigates its potential antihypertensive action mechanism. DNA encoding sequence of recombinant peptide was designed to form in tandem, which was expressed in Escherichia coli BL21 (DE3).

Feasibility and acceptability of the delivery of a group telehealth intervention for support persons of patients receiving buprenorphine for opioid use disorder.

Background: Opioid-related overdoses increased substantially during the COVID-19 pandemic, eliciting an urgent demand for accessible treatment for individuals with opioid use disorder (OUD) and those who support them (support persons). Support persons can improve treatment initiation and retention in their individuals with OUD. Additionally, support persons may have their own mental health needs related to their loved one's OUD.

Recombinant Antibodies Inhibit Enzymatic Activity of the E3 Ubiquitin Ligase CHIP via Multiple Mechanisms.

Carboxyl-terminus of Hsp70-Interacting Protein (CHIP) is an E3 ubiquitin ligase that marks misfolded substrates for degradation. Hyper-activation of CHIP has been implicated in multiple diseases, including cystic fibrosis and cancer, suggesting that it may be a potential drug target. However, there are few tools available for exploring this possibility.

Cyclosporine Treatment in Patients with Kawasaki Disease and Coronary Artery Aneurysms or Treatment Resistance.

Objective: To describe the clinical course and outcome of 33 patients with Kawasaki disease (KD) treated with cyclosporine (CSA) for coronary artery abnormalities (CAA) or treatment resistance.

Study Design: Single-center, retrospective study of patients with KD treated from 2013 through 2023 for CAA or treatment resistance. Demographics, laboratory studies, medications, adverse events, and echocardiographic data were analyzed.

Long Term Results of a Comparative Study of Percutaneous and Surgically Created Proximal Forearm Arteriovenous Fistulae.

Objective: This retrospective, single centre, comparative effectiveness study aimed to compare the long term outcomes of percutaneous arteriovenous fistulae (pAVF) and surgically created arteriovenous fistulae (sAVF) created in the proximal forearm for haemodialysis access.

Methods: Data were reviewed from a prospectively maintained database on patients who underwent pAVF or sAVF creation from September 2017 to September 2023. A total of 217 pAVFs (61 WavelinQ and 156 Ellipsys) and 158 sAVFs were analysed.

Trends in Neurosurgeons Signing Medicare Opt-Out Affidavits.

Objective: In recent decades, many physicians have chosen to opt out of Medicare, allowing them to set their own pricing models for their patients. Characterization of Medicare opt-outs has not been thoroughly studied in any surgical specialty, including Neurosurgery. Our study characterizes the factors that may influence a neurosurgeon's decision to opt out of Medicare acceptance and contextualizes them both within the field and across various surgical specialties.

Six-month safety and efficacy outcomes from the randomized-controlled arm of the WRAPSODY Arteriovenous Access Efficacy (WAVE) trial.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.

Nutrient control of splice site selection contributes to methionine addiction of cancer.

Objectives: Many cancer cells depend on exogenous methionine for proliferation, whereas non-tumorigenic cells can divide in media supplemented with the metabolic precursor homocysteine. This phenomenon is known as methionine dependence of cancer or methionine addiction. The underlying mechanisms driving this cancer-specific metabolic addiction are poorly understood.

Development of a transdermal gel for reversible male contraception.

While there are several easy-to-use reversible female contraceptives, little is available for men. Introduction of novel, cost-effective male contraceptives could have important downstream global health and economic benefits. Currently, nearly half of all pregnancies globally are unintended, with many resulting in unsafe abortions, a significant burden for women and families in many countries.

Therapeutic outcomes and safety of radiofrequency ablation for primary papillary thyroid carcinoma: A game-changing meta-analysis.

Background: Radiofrequency ablation (RFA) is an emerging treatment option for small, low-risk papillary thyroid carcinoma (PTC). This systematic review and meta-analysis aimed to evaluate and compare the efficacy and safety profiles of RFA for primary T1a vs. T1b PTC.

Intranasal oxytocin for apathy in people with frontotemporal dementia (FOXY): a multicentre, randomised, double-blind, placebo-controlled, adaptive, crossover, phase 2a/2b superiority trial.

Background: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal in limbic brain regions. We aimed to determine whether longer treatment with oxytocin improves apathy in people with frontotemporal dementia.

Safety and efficacy of satralizumab in patients with generalised myasthenia gravis (LUMINESCE): a randomised, double-blind, multicentre, placebo-controlled phase 3 trial.

Background: Evidence from preclinical studies suggests that IL-6 signalling has the potential to modulate immunopathogenic mechanisms upstream of autoantibody effector mechanisms in patients with generalised myasthenia gravis. We aimed to assess the safety and efficacy of satralizumab, a humanised monoclonal antibody targeting the IL-6 receptor, in patients with generalised myasthenia gravis.

Methods: LUMINESCE was a randomised, double-blind, placebo-controlled, multicentre, phase 3 study at 105 sites, including hospitals and clinics, globally.

Advancing long-read nanopore genome assembly and accurate variant calling for rare disease detection.

More than 50% of families with suspected rare monogenic diseases remain unsolved after whole-genome analysis by short-read sequencing (SRS). Long-read sequencing (LRS) could help bridge this diagnostic gap by capturing variants inaccessible to SRS, facilitating long-range mapping and phasing and providing haplotype-resolved methylation profiling. To evaluate LRS's additional diagnostic yield, we sequenced a rare-disease cohort of 98 samples from 41 families, using nanopore sequencing, achieving per sample ∼36× average coverage and 32-kb read N50 from a single flow cell.

Ligand interaction landscape of transcription factors and essential enzymes in E. coli.

Knowledge of protein-metabolite interactions can enhance mechanistic understanding and chemical probing of biochemical processes, but the discovery of endogenous ligands remains challenging. Here, we combined rapid affinity purification with precision mass spectrometry and high-resolution molecular docking to precisely map the physical associations of 296 chemically diverse small-molecule metabolite ligands with 69 distinct essential enzymes and 45 transcription factors in the gram-negative bacterium Escherichia coli. We then conducted systematic metabolic pathway integration, pan-microbial evolutionary projections, and independent in-depth biophysical characterization experiments to define the functional significance of ligand interfaces.

Cross-Sectional Study Gender Pay Gap in Industry General Payments to U.S. General and Fellowship-Trained Surgeons.

Introduction: Gender disparities exist in nonresearch industry payments to U.S. physicians, but detailed analyses specific to surgeons are limited.

The Anatomy of Gossip: Dissecting Dynamics and Impacts in Surgical Residency.

Background: Gossip, defined by social scientists as "evaluative talk about an absent third party," is anecdotally pervasive yet poorly understood in surgical residency programs. Gossip is known to have both positive and negative impacts. This study sought to deconstruct the role of gossip in surgical residency and evaluate its impact through the lens of surgical residents.

Immunology of Biliary Atresia.

Biliary atresia is a progressive neonatal cholangiopathy that leads to liver failure. Characterized by inflammation-mediated liver injury, the immune system plays a critical role in the pathogenesis of this disease. Though several types of immune cells and mediators have been implicated in animal models of biliary atresia, emerging literature reflects the complex interplay of components of the immune response that contributes to disease progression in humans.

Recipes and ingredients for deep learning models of 3D genome folding.

Three-dimensional genome folding plays roles in gene regulation and disease. In this review, we compare and contrast recent deep learning models for predicting genome contact maps. We survey preprocessing, architecture, training, evaluation, and interpretation methods, highlighting the capabilities and limitations of different models.

Promoting interactional health equity through (Complementary and Integrative Health) talk during clinical encounters.

Objectives: Complementary and Integrative Health (CIH) is recognized as a set of modalities to bolster health and well-being often outside of standard biomedical practice. How people discuss CIH with their biomedical providers is a microcosm for health communication more generally. In this Discussion, we propose a revision of the Street et al.

The Hao-Fountain syndrome protein USP7 regulates neuronal connectivity in the brain via a novel p53-independent ubiquitin signaling pathway.

Mutation or deletion of the deubiquitinase USP7 causes Hao-Fountain syndrome (HAFOUS), which is characterized by speech delay, intellectual disability, and aggressive behavior and highlights important unknown roles of USP7 in the nervous system. Here, we conditionally delete USP7 in glutamatergic neurons in the mouse forebrain, triggering disease-relevant phenotypes, including sensorimotor deficits, impaired cognition, and aggressive behavior. Although USP7 deletion induces p53-dependent neuronal apoptosis, most behavioral abnormalities in USP7 conditional knockout mice persist following p53 loss.
