Temporal Dynamics of Complement Activation and Outcome in Patients With Acute Ischemic Stroke

BACKGROUND: Immune-mediated inflammatory responses exacerbate brain injury and affect the prognosis in acute ischemic stroke. METHODS: We characterized longitudinal complement activation after acute ischemic stroke using serial plasma samples from 10 patients and 8 controls. Init...

Chemogenetic ubiquitin E1 inhibitor TAK-243 CRISPR screen uncovers HAPSTR1/HUWE1 axis in chromatin proteostasis and cell cycle control

In this study, we sought to comprehensively map ubiquitin signaling networks at the crossroads of cellular proliferation and proteostasis, both crucial in cancer. Genome-wide CRISPR knockout screening in the presence of the ubiquitin E1 inhibitor TAK-243 identified 239 genes whos...

Post-acute sequelae of COVID-19 (PASC) are associated with distinct clinical phenotypes two years after SARS-CoV-2 infection: A data-driven approach

It is important to determine whether the persistent cognitive and fatigue complaints, as part of post-acute sequelae of COVID-19 (PASC), are associated with underlying patterns and specific symptoms clusters. Therefore, the aim of the present study was to investigate symptom clus...

Home-based geriatric rehabilitation after shortened inpatient rehabilitation: cost-effectiveness analysis of the “Better@Home” multicentre prospective cohort study with a matched historical control group

PURPOSE: Geriatric rehabilitation (GR) is facing increased demand due to population ageing. Home-based GR could reduce reliance on resource-intensive inpatient care. However, evidence is limited regarding the cost-effectiveness of home-based GR. The aim of this study is to assess...

Sex‐ and age‐specific daily and seasonal rhythms in haemoglobin and ferritin among Dutch blood donors

Abstract Background and Objectives Intra‐individual haemoglobin (Hb) and ferritin variation is often overlooked in clinical practice, yet may be relevant where levels are around the cut‐offs. We characterised Hb and ferritin fluctuations across the year and day in Dutch blood don...

The Influence of Deep Hypothermic Circulatory Arrest on the Incidence of Postoperative Acute Kidney Injury After Pulmonary Endarterectomy

Background: Pulmonary endarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) is performed using phases of deep hypothermic circulatory arrest (DHCA). DHCA has been discussed as a risk factor for cardiac surgery-associated acute kidney injury (...

Dried Urine Spots for Quantification of C0 (Free) Carnitine Excretion: A Validated Method for Follow-Up and Confirmatory Testing of Primary Carnitine Deficiency

Primary carnitine deficiency (PCD), caused by Organic Cation Transporter Novel 2 (OCTN2) deficiency, is detected by newborn screening (NBS) through low blood free carnitine (C0) concentrations. Confirmation of the diagnosis may be supported by demonstrating increased urinary C0 e...

Surgical waiting times in patients with high‐ and low‐risk renal cell carcinoma in England

Objectives To assess to what extent hospitals meet the uniform English National Health Service ‘timely’ treatment standard, what happens after a breach, and determinants of delay for patients with high‐risk renal cell carcinoma (RCC). Patient and Methods Population‐based study us...

Necroptosis as a key player in cervical cancer progression and management: a systematic review and transcriptomic cross-study consensus analysis

Immunotherapy has improved outcomes for a subset of patients with locally advanced cervical cancer. However, many tumors remain immunologically "cold" and fail to respond. Strategies that enhance tumor immunogenicity are therefore of increasing interest. Necroptosis, a regulated...

A living systematic review, meta-analysis, and open data resource of trials of MDMA-assisted therapy for PTSD

Abstract 3,4-Methylenedioxymethamphetamine (MDMA) has emerged as a potential treatment for post-traumatic stress disorder (PTSD). However, rapidly changing evidence in a fast-moving field can be challenging to integrate. Here, we present a living systematic review and open-data m...

Immunohistochemistry for c-MET, HLA class II, and CD68 does not show prognostic value in early-stage classic Hodgkin lymphoma patients in the EORTC-GELA H9 intergroup randomised trial

Background In classic Hodgkin lymphoma (cHL), identifying high-risk patients is crucial for tailored treatment. Clinical risk factors are useful, but there is room for improvement. Although many diagnostic tissue-based biomarkers have been described to correlate with prognosis, n...

Towards a suitable biomarker for childhood screening for familial hypercholesterolemia: a systematic literature review

Familial hypercholesterolemia (FH) is a common genetic disorder causing elevated low-density lipoprotein cholesterol (LDL-c) concentrations from birth, resulting in a high risk of premature cardiovascular disease. Despite effective early treatment, FH remains underdiagnosed in ch...

Escherichia coli -derived enterobactin is associated with delayed gut microbiome maturation in infants born to mothers with obesity

ABSTRACT Maternal obesity has been increasingly recognized as a factor influencing early-life microbiome development. However, its impact on the infant gut resistome and virulome remains insufficiently characterized. In this prospective longitudinal study, we investigated gut mic...

Clinical Trial: Dupilumab Improves Eosinophilic Oesophagitis Outcomes Versus Placebo Regardless of Comorbidities or Treatment History in a Randomised Clinical Trial

BACKGROUND: Patients with eosinophilic oesophagitis (EoE) can present with differing disease characteristics, treatment resistance, and associated type 2 inflammatory comorbidities. We assessed the efficacy of dupilumab in subgroups of patients with EoE from the LIBERTY EoE TREET...

MAIA frailty subgroup analysis: long-term follow-up with daratumumab plus lenalidomide/dexamethasone in transplant-ineligible newly diagnosed myeloma

Abstract In MAIA (Daratumumab, lenalidomide, and dexamethasone versus lenalidomide and dexamethasone alone in newly diagnosed multiple myeloma), daratumumab plus lenalidomide/dexamethasone (D-Rd) improved progression-free survival (PFS) and overall survival (OS) versus Rd in tran...

From Sprain to End-Stage Osteoarthritis: Why Earlier Intervention in Ankle Cartilage Damage Deserves More Attention

➢ Ankle cartilage damage ranges from osteochondral lesions of the talus to end-stage osteoarthritis. End-stage ankle osteoarthritis has been associated with a health burden comparable with that of major chronic diseases such as congestive heart failure and kidney disease, while p...

Impact of Ganglionated Plexus Ablation on Early Recurrence After Thoracoscopic Atrial Fibrillation Ablation: A Post Hoc Analysis of the AFACT Study

ABSTRACT Background Early recurrences of atrial fibrillation (AF) after ablation are often considered transient. However, they may be caused by a combination of temporary and permanent proarrhythmogenic factors. Objective We evaluated whether adjunctive GP ablation was associated...

Monitoring huntingtin aggregation in Huntington’s disease: methods, challenges and future opportunities

INTRODUCTION: Huntington's disease is characterized by the progressive misfolding and aggregation of mutant huntingtin, a dynamic process generating a heterogeneous spectrum of soluble oligomers, fibrillar assemblies and inclusion bodies. Increasing evidence suggests that distinc...

Liver X receptor (LXR) signaling in macrophage inflammation and cardiometabolic disease.

Cardiometabolic diseases profoundly remodel tissue immune landscapes, characterized by the accumulation of diverse macrophage subtypes. Among these, lipid-associated macrophages (LAMs) have emerged as an important subset that is frequently observed in cardiometabolically affected...
