Heterozygous UBR5 variants result in a neurodevelopmental syndrome with developmental delay, autism, and intellectual disability.

E3 ubiquitin ligases have been linked to developmental diseases including autism, Angelman syndrome (UBE3A), and Johanson-Blizzard syndrome (JBS) (UBR1). Here, we report variants in the E3 ligase UBR5 in 29 individuals presenting with a neurodevelopmental syndrome that includes developmental delay, autism, intellectual disability, epilepsy, movement disorders, and/or genital anomalies. Their phenotype is distinct from JBS due to the absence of exocrine pancreatic insufficiency and the presence of autism, epilepsy, and, in some probands, a movement disorder.

Cell therapy with human IL-10-producing ILC2s limits xenogeneic graft-versus-host disease by inhibiting pathogenic T cell responses.

Interleukin-10 (IL-10)-producing group 2 innate lymphoid cells (ILC2) regulate inflammatory immune responses, yet their therapeutic potential remains largely unexplored. Here, we demonstrate that cell therapy with human ILC2 inhibits pathogenic T cell responses in humanized mouse models of graft-versus-host disease (GVHD), resulting in reduced GVHD severity and improved overall survival without limiting the graft-versus-leukemia effect. ILC2 conferred superior protection from GVHD than IL-10 ILC2s, and blocking IL-10 and IL-4 abrogated ILC2 protective effects, indicating that these cytokines are important for the protective effects of ILC2.

Single cell profiling of hematopoietic stem cell transplant recipients reveals TGF-β1 and IL-2 confer immunoregulatory functions to NK cells.

Natural killer (NK) cell activity is influenced by cytokines and microenvironment factors, resulting in remarkably diverse functions, by contributing to inflammatory responses or serving as rheostats of adaptive immunity. Using single cell RNA sequencing (scRNA-seq), we identified a CD56NK cell population associated with hematopoietic stem cell transplant recipients protected from acute graft-versus-host disease (GVHD). We further define a role for the combination of interleukin-2 (IL-2) and transforming growth factor β1 (TGF-β1) in promoting a regulatory phenotype in NK cells.

Blood biomarker discovery for autism spectrum disorder: A proteomic analysis.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and social interaction and restricted, repetitive patterns of behavior, interests, or activities. Given the lack of specific pharmacological therapy for ASD and the clinical heterogeneity of the disorder, current biomarker research efforts are geared mainly toward identifying markers for determining ASD risk or for assisting with a diagnosis. A wide range of putative biological markers for ASD are currently being investigated.

A prospective blinded diagnostic accuracy study to assess the accuracy of fetal weight estimation at term by clinical method using Leopold's maneuvers and ultrasonography in predicting the actual birth weight.

Context: Over-medicalization of normal pregnancy is associated with unnecessary inductions of labor leading to operative deliveries. In a busy outpatient department (OPD) or low-resource setup where ultrasound availability, experience, and cost will be a concern, routine ultrasound at term can be avoided if the clinical estimation of fetal weight is more or less equal to the actual birth weight.

Aims: To assess the reliability and validity of fetal weight estimation at term by ultrasound and clinical estimation.

Point-of-care ultrasound in palliative medicine residency programs: report of a national survey and local workshop.

Purpose: Point-of-care ultrasound (POCUS) is used in various clinical specialties to improve diagnostic and procedural accuracy and has many potential applications in palliative care. However, it is unclear what is the current state of training and use of POCUS in palliative care in Canada. Our objectives were to understand the current state of training and use of POCUS in Canadian Palliative Medicine subspecialty residency programs and to develop and implement a local training workshop for POCUS in palliative care.

A Case of Malignant Pleural Mesothelioma With Unknown Asbestos Exposure.

Malignant pleural mesothelioma (MPM) is a rare, locally invasive tumor that develops from mesothelial cells lining the lung's pleura. It is mostly associated with prolonged asbestos exposure. The long latency period between asbestos exposure and clinical symptoms makes diagnosing MPM challenging.

Access Barriers to Anti-CD19+ CART-Cell Therapy for NHL Across a Community Transplant and Cellular Therapy Network.

We analyzed access barriers to anti-CD19+ chimeric antigen receptor T-cells (CART) for non-Hodgkin lymphoma (NHL) within a community-based transplant and cell therapy network registry. 357 intended recipients of FDA-approved anti-CD19+ CART were identified in the study period (2018 to 2022). Results showed that the median age at referral was 61 years, referral year was 2018 (4%), 2019 (14%), 2020 (18%), 2021 (26%), and 2022 (38%).

Background: Many mothers experience poor psychological outcomes during their perinatal period. The presence of depression and anxiety has a significant adverse impact on the mother's health and the infant's development.

Aim: This review aimed to examine the effectiveness of peer support interventions in improving depression, anxiety, and perceived social support among mothers during the perinatal period.

Differential Patterns of Gut and Oral Microbiomes in Hispanic Individuals with Cognitive Impairment.

Alzheimer's disease and related dementias (ADRD) have been associated with alterations in both oral and gut microbiomes. While extensive research has focused on the role of gut dysbiosis in ADRD, the contribution of the oral microbiome remains relatively understudied. Furthermore, the potential synergistic interactions between oral and gut microbiomes in ADRD pathology are largely unexplored.

Leptin bioavailability and markers of brain atrophy and vascular injury in the middle age.

Introduction: We investigated the associations of leptin markers with cognitive function and magnetic resonance imaging (MRI) measures of brain atrophy and vascular injury in healthy middle-aged adults.

Methods: We included 2262 cognitively healthy participants from the Framingham Heart Study with neuropsychological evaluation; of these, 2028 also had available brain MRI. Concentrations of leptin, soluble leptin receptor (sOB-R), and their ratio (free leptin index [FLI]), indicating leptin bioavailability, were measured using enzyme-linked immunosorbent assays.

Impact of prior inotuzumab ozogamicin treatment on brexucabtagene autoleucel outcomes in adults with B-cell ALL.

The effect of prior inotuzumab ozogamicin (InO) treatment on brexucabtagene autoleucel (brexu-cel) outcomes remains unclear in adults with acute lymphoblastic leukemia (ALL). We conducted a retrospective multicenter analysis of 189 patients with relapsed/refractory ALL treated with brexu-cel. Over half of the patients received InO before brexu-cel (InO exposed).

The burden of diabetes-associated multiple long-term conditions on years of life spent and lost.

Diabetes mellitus is a central driver of multiple long-term conditions (MLTCs), but population-based studies have not clearly characterized the burden across the life course. We estimated the age of onset, years of life spent and loss associated with diabetes-related MLTCs among 46 million English adults. We found that morbidity patterns extend beyond classic diabetes complications and accelerate the onset of severe MLTCs by 20 years earlier in life in women and 15 years earlier in men.

Recommendations for Development and Validation of a Fit-For-Purpose Biomarker Assays Using Western Blotting; An-AAPS Sponsored Initiative to Harmonize Industry Practices.

Western blot (WB) assays are routinely used for detection and quantification of biomarkers. Although assay validation to measure biomarkers in complex matrices has become a mainstay process for ligand binding assays (LBA) and mass spectrometry (MS), no guidelines exist yet validate biomarker methods using WB techniques. In this cross-industry white paper, we outlined in detail the key steps for development and for validation of WB assays for protein biomarkers under different contexts of use (COU).

Vis-SPLIT: Interactive Hierarchical Modeling for mRNA Expression Classification.

We propose an interactive visual analytics tool, Vis-SPLIT, for partitioning a population of individuals into groups with similar gene signatures. Vis-SPLIT allows users to interactively explore a dataset and exploit visual separations to build a classification model for specific cancers. The visualization components reveal gene expression and correlation to assist specific partitioning decisions, while also providing overviews for the decision model and clustered genetic signatures.

Reconciling lesions, relapses and smouldering associated worsening: A unifying model for multiple sclerosis pathogenesis.

The failure of relapses and white matter lesions to properly explain long-term disability and progression in multiple sclerosis is compounded by its artificial separation into relapsing remitting, secondary progressive, and primary progressive pigeonholes. The well-known epidemiological disconnection between relapses and long-term disability progression has been rediscovered as "progression independent of relapse activity", i.e.

Effects of Parental Predictors on Postpartum Depression.

Background: Postpartum depression (PPD) is highly prevalent and plagues a significant proportion of parents. Postpartum depression also exerts various negative consequences on infant development and parent-infant relationships. Social support is identified as an important factor influencing many parental predictors, and may affect the development of PPD.
