Donor-derived cell-free DNA (dd-cfDNA) is an emerging non-invasive biomarker for allograft injury detection. This study aimed to evaluate a new, decentralized dd-cfDNA testing kit against a centralized dd-cfDNA testing service broadly utilized in the United States. Kidney transplant recipients with decentralized and centralized dd-cfDNA measurements and concomitant kidney allograft biopsies were included in the study.

Multiple sclerosis (MS) is a neurodegenerative disease that affects the central nervous system. Structures affected in MS include the corpus callosum, connecting the hemispheres. Studies have shown that in mammalian brains, structural connectivity is organized according to a conservation principle, an inverse relationship between intra- and interhemispheric connectivity.

Background: Attention-deficit/hyperactivity disorder (ADHD) is a common neuro-developmental disorder that often persists into adulthood. Moreover, it is frequently accompanied by bipolar disorder (BD) as well as borderline personality disorder (BPD). It is unclear whether these disorders share underlying pathomechanisms, given that all three are characterized by alterations in affective states, either long or short-term.

Background: Left bundle branch area pacing (LBBAP) needs confirmation of left conduction system capture assessed by testing of different electrical parameters. Guidelines recommend the use of an electrophysiology recording system (EP-RS) to guide conduction system pacing procedures. However, some experienced centers perform LBBAP procedures without an EP-RS.

Treatment of attention-deficit/ hyperactivity disorder (ADHD) in patients with a substance use disorder (SUD) and comorbid ADHD (SUD +ADHD) may have positive effects on the outcome of both conditions, but controversy exists regarding the preferred ADHD treatment in these patients. Little is known about the treatments that are provided for these patients in routine addiction care practice and the factors that are associated with treatment provision. To describe the treatments provided in everyday clinical practice and to explore factors associated with ADHD treatment provision in patients with SUD +ADHD.

Background: Studies have shown associations between polygenic risk scores for educational attainment (PRS), cognitive reserve (CR), cognition, negative symptoms (NS), and psychosocial functioning in first-episode psychosis (FEP). However, their specific interactions remain unclear. This study aimed to investigate the mediating roles of CR, cognition, and NS in the relationship between PRS and psychosocial functioning one year after a FEP.

Psychopathological manifestations and cognitive impairments are core features of psychotic disorders. Polygenic risk scores (PRS) offer insights into the relationships between genetic vulnerability, symptomatology, and cognitive impairments. This study used a network analysis to explore the connections between PRS, cognition, psychopathology, and overall functional outcomes in individuals experiencing a first episode of psychosis (FEP).

Emerging evidence suggests that retinal structural alterations are present in schizophrenia spectrum disorders (SSD), potentially reflecting broader neurodevelopmental and neurodegenerative processes. This cross-sectional study investigates retinal thickness and its clinical correlations in a sample of early-course SSD patients compared to healthy controls (HCs). One hundred-two eyes from 26 SSD cases and 25 age- and sex-matched HCs were included.

Background: The global incidence of type 2 diabetes (T2D) is rapidly increasing, with retinopathy being its most common complication and a leading cause of preventable blindness. Although the precise mechanisms involved in the development of diabetic retinopathy (DR) are not fully understood, defective immunomodulation is a recognized key factor in its pathophysiology. Regulatory T cells (Treg) regulate inflammation and promote regeneration, and while they are known to have important anti-inflammatory and neuroprotective roles in other tissues, including central nervous system, their role in the diabetic retina remains largely unknown.

Background: The double-stent retriever (SR) technique has been described as an effective rescue technique when single-SR fails to induce recanalization. We aimed to assess the safety and efficacy of first-line double-SR in patients with stroke undergoing thrombectomy.

Autophagy is a vital cellular process responsible for the degradation of proteins, organelles, and other cellular components within lysosomes. In neurons, basal autophagy is indispensable for maintaining cellular homeostasis and protein quality control. Accordingly, lysosomal dysfunction has been proposed to be associated with neurodegeneration, and with Parkinson's disease (PD) in particular.

Aim: To investigate the natural progression of SGCE-associated myoclonus dystonia from symptom onset in childhood to early adulthood.
Method: Myoclonus and dystonia were monitored using rating scales in two cohorts of participants from Spain and the Netherlands. Individual annualized rates of change were calculated and longitudinal trends were assessed using Bayesian mixed models.

Background: Emerging evidence suggests a potential association between "leaky gut syndrome" and low-grade systemic inflammation in individuals with psychiatric disorders, such as schizophrenia. Gut dysbiosis could increase intestinal permeability, allowing the passage of toxins and bacteria into the systemic circulation, subsequently triggering immune-reactive responses. This study delves into understanding the relationship between plasma markers of intestinal permeability and symptom severity in schizophrenia.

MFN1 (mitofusin 1) and MFN2 are key players in mitochondrial fusion, endoplasmic reticulum (ER)-mitochondria juxtaposition, and macroautophagy/autophagy. However, the mechanisms by which these proteins participate in these processes are poorly understood. Here, we studied the interactomes of these two proteins by using CRISPR-Cas9 technology to insert an HA-tag at the C terminus of MFN1 and MFN2, and thus generating HeLa cell lines that endogenously expressed MFN1-HA or MFN2-HA.

Background: Metrics evaluating the functional quality of red blood cells (RBCs) must consider their role in oxygen delivery. Whereas oxygen-carrying capacity is routinely reported using haemoglobin assays, the rate of oxygen exchange is not measured, yet also important for tissue oxygenation. Since oxygen-unloading depends on the diffusion pathlength inside RBCs, cell geometry offers a plausible surrogate.

Aims: European Systematic Coronary Risk Assessment 2 for Older Persons (SCORE2-OP) model has shown modest performance when externally validated in selected cohorts. We aim to investigate its predictive performance and clinical utility for 10-years cardiovascular (CV) risk in an unbiased and representative cohort of older people of a low CV risk country. Furthermore, we explore whether other clinical or echocardiographic features could improve its performance.

Background And Objectives: The role of the complement system in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is not completely understood, and studies exploring its potential utility for diagnosis and prognosis are lacking. We aimed to investigate the value of complement factors (CFs) as diagnostic and prognostic biomarkers in patients with MOGAD.
Methods: Multicentric retrospective cohort study including patients with MOGAD, multiple sclerosis (MS) and aquaporin-4 seropositive neuromyelitis optica spectrum disorder (AQP4-NMOSD) with available paired serum and CSF samples.

Background: Umbilical cord blood (CB) units stored in banks are an important source of hematopoietic stem cells for transplantation and other cell therapies. New applications, such as their use in transfusions, require rapid quality release as cord blood red blood cells (CB-RBC) have a shorter shelf life.
Study Design And Methods: This project aims to investigate the most prevalent microbial contaminants in CB preparations and validate a rapid sterility testing strategy for CB-RBC based on an automated system (BACT/ALERT®) in tandem with a molecular assay (real-time PCR) capable of detecting at least 100 CFU/mL of Cutibacterium acnes in CB-RBC to accelerate the detection of the most common slow-growing bacteria.
