How age and sex interaction is associated with immune aging with implications for vaccines and age-related autoimmunity

Immunosenescence is not a uniform decline but a trajectory shaped jointly by age and sex. Using continuous high-dimensional immunophenotyping, we show that aging T cells accumulate a senescent signature of CD28 loss and CD57 gain, and that males reach an inverted CD4:CD8 ratio ea...

Correlation of polygenic risk score and clinical phenotype in patients with genetic generalized epilepsy

Abstract Objective The polygenic risk score (PRS) for individuals with genetic generalized epilepsy (GGE) quantifies the common risk variants in genes identified in genome‐wide association studies. We hypothesized that the phenotype of GGE patients differs based on their GGE PRS....

Modulation of neuronal excitability and plasticity by BHLHE41 conveys lithium non-responsiveness

Abstract Many bipolar disorder (BD) patients are non-responsive to lithium. The mechanisms underlying lithium (non-)responsiveness are largely unknown. By using gene-set enrichment analysis methods, we found that core clock gene-sets are significantly associated with lithium resp...

Global Real‐World Outcomes of Olaparib in Metastatic Castration‐Resistant Prostate Cancer Patients With Homologous Recombination Repair Alterations

Evidence to guide the treatment for patients with metastatic castration-resistant prostate cancer (mCRPC) and Homologous Recombination Repair (HRR) gene alterations outside of clinical trials remains limited. This was an observational, cohort study, including mCRPC patients with...

Development and evaluation of a German Paediatric Trigger Tool (PAED-TT-GER) for detecting adverse events in hospitalized children

Abstract Trigger tools (TTs) are highly recommended for structured detection of adverse events (AEs) through retrospective medical record review. However, available general tools require thorough adaptation to paediatric care and local documentation practices to ensure feasibilit...

Longitudinal progression, metrics, age-dependence, and modifiers of ataxia severity in SCA27B: a multicentre study of 219 patients

Background Spinocerebellar Ataxia 27B (SCA27B) is a novel, frequent and likely treatable late-onset autosomal-dominant ataxia caused by GAA repeat-expansions in FGF14 . For understanding disease evolution and imminent trial planning, metrics of the most widely used clinical outco...

Exploring the association between genetic polymorphisms in FGFR2 and children’s facial morphology

Abstract Background Studies on animal models and fibroblast growth factor receptor (FGFR2)-associated craniosynostosis syndromes suggest that FGFR2 plays a crucial role in craniofacial development. Therefore, the present exploratory study aims to investigate the relationship betw...

A novel diagnostic technology rapidly detects the presence of infection and defines antimicrobial sensitivities in organisms typical for joint infection

Aims Infective arthritis is rare, but serious. Timely treatment with appropriate antimicrobial therapy is potentially life- and limb-saving, but our ability to deliver this is limited by current laboratory practices, which confer a delay of several days before antimicrobial sensi...

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures

We developed a high-content screening to investigate how Alzheimer’s disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently d...

COPI Coatomer Regulates Several Steps of HDL Metabolism

Abstract Background Reverse cholesterol transport by high density lipoproteins (HDL) is considered as an anti-atherogenic metabolic pathway. Hepatocytes determine the efficacy of this pathway by the production of apolipoprotein A-I (apoA-I) and its lipidation by ATP binding casse...

Impact of CT incidental lung findings and pulmonary function on 3-year mortality after transcatheter aortic valve replacement (TAVR)

Background: Incidental pulmonary findings, particularly interstitial lung abnormalities (ILA) and emphysema are frequently observed in preprocedural computed tomography (CT) scans of patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). Howe...

Procalcitonin as a predictor of length of stay in patients with odontogenic infections

OBJECTIVES: Our study aimed to evaluate procalcitonin (PCT) as a prognostic marker in advanced odontogenic infections. In addition, we sought to identify further prognostic markers that could be used to predict the length of hospital stay (LOS). MATERIALS AND METHODS: We retrospe...

A three-metabolite microbiota-associated signature for early risk stratification of gestational diabetes mellitus

Gestational diabetes mellitus (GDM) is associated with adverse pregnancy outcomes and long-term metabolic and cardiovascular risk. However, oral glucose tolerance testing at 24–28 gestational weeks limits early risk stratification. Gut microbiota-associated metabolites may reflec...

DECIDER-2: Prospective randomized multicenter phase III trial of decitabine and venetoclax administered in combination with all-trans retinoic acid or placebo in patients with acute myeloid leukemia who are ineligible for induction chemotherapy

Abstract Background Acute myeloid leukemia (AML) is predominantly a disease of older patients with a poor long-term survival. Approval of the combination of venetoclax (VEN) with azacitidine (AZA) or decitabine (DAC) in the European Union in 2021 for the treatment of patients wit...
