Maternal perinatal anxiety and infant primary care use in 1998-2016: a UK cohort study.

Background: There is some evidence that perinatal anxiety (PNA) is associated with lower rates of infant vaccinations and decreased access to preventative infant healthcare, but results across studies have not been conclusive.

Objective: To investigate the relationship between maternal PNA and infant primary care use.

Methods: Cohort study of mother-infant pairs identified between 1998 and 2016 using IQVIA Medical Research Database (IMRD).

Biomarkers.

Background: The earliest recognized biomarker of AD is deposition of Aβ amyloid that leads to formation of plaques and may, over time, trigger or at least be followed by gliosis/neuroinflammation and neurofibrillary tangles, accompanied by neurodegenerative changes including neuronal and synaptic loss. We have previously reported that semaphorin 4D (SEMA4D), the major ligand of plexin B receptors expressed on astrocytes, is upregulated in diseased neurons during progression of AD and Huntington's disease (HD). Binding of SEMA4D to PLXNB receptors triggers astrocyte reactivity, leading to loss of neuroprotective homeostatic functions, including downregulation of glutamate and glucose transporters (doi:10.

Tuning the Performance of Metalloporphyrin-Based Pressure-Sensitive Paints through the Nature of the Central Metal Ion.

Since the 1980s, pressure-sensitive paint (PSP) has been used as an optical pressure sensor for measuring surface pressure on aircraft models in wind tunnels. Typically, PSPs have utilized platinum(II)-5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)-porphyrin due to its high pressure sensitivity, phosphorescence lifetime of ∼50 μs, reasonable quantum yield of emission, and resistance to photo-oxidation. This work investigates the photophysics and electronic structure of metal complexes of 5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)-porphyrin, namely, Zn(II), Pd(II), and Ir(III), as potentially improved luminophores for polymer-based PSPs.

Dual CD47 and PD-L1 blockade elicits anti-tumor immunity by intratumoral CD8 T cells.

Objectives: Bispecific antibodies targeting CD47 and PD-L1 (CD47 × PD-L1 BisAb) demonstrate efficacy against a range of solid cancers. While dual blockade negates anti-CD47-mediated toxicity, the effect of combined innate and adaptive immune activation on protective tumor-resident CD8 T cells has yet to be fully elucidated.

Methods: CD8 T cell populations were tracked upon CD47 × PD-L1 BisAb treatment in an orthotopic model of murine breast cancer where anti-tumor immunity is mediated by CD8 T cells.

Using youth participatory action research to explore the impacts of structural violence on LGBTQIA + youth health.

Queerphobia is defined as society's negative attitude towards LGBTQIA + people, translating into structures that marginalise LGBTQIA + people and contribute to health inequities that cause real harm and can be understood as structural violence. The purpose of this article is to explore what historically marginalised youth in a youth participatory action research (YPAR) project characterise as the big picture issues affecting the lives of LGBTQIA + youth. We used participatory arts-based methods to conduct community and identity building, define research questions and photo prompts, conduct data collection, engage in group thematic analysis, and make recommendations at the state policy level.

Emerging roles of astrocytes as immune effectors in the central nervous system.

The astrocyte, a major glial cell type in the central nervous system (CNS), is widely regarded as a functionally diverse mediator of homeostasis. During development and throughout adulthood, astrocytes have essential roles, such as providing neuron metabolic support, modulating synaptic function, and maintaining the blood-brain barrier (BBB). Recent evidence continues to underscore their functional heterogeneity and importance for CNS maintenance, as well as how these cells ensure optimal CNS and immune responses to disease, acute trauma, and infection.

Local Thermochemical Mechanisms in Direct Solar Graphite Synthesis from Methane.

Methane pyrolysis is known to produce hydrogen and solid carbon in a variety of thermal processes. However, the generated carbon product typically belongs to a low-value amorphous type. Here, we elucidate the thermochemical mechanisms of a reaction that produces high-quality graphite via direct solar methane pyrolysis on a porous substrate.

Defining the Role of the Fire and Rescue Service in Mental Health Support for Older Adults: A Qualitative Study.

Introduction: Anxiety and depression in older adults (60+ years of age) are under-diagnosed and under-treated. Older adults are less likely to seek help for these problems due to a lack of awareness, difficulty accessing health care due to availability or disability and fear of loss of independence. Existing points of contact between older adults and non-traditional services, for example, the Fire and Rescue Service (FRS), could provide opportunities to support help-seeking for mental ill-health.

The relationships between the campus built environment and walking activity.

Despite the gradual development of students' sedentary habits and associated health problems, only a few studies have extensively and systematically measured campus built environments (CBE) and their impact on street walking activity. This study explores the association between CBEs and pedestrian volume (PV). Comprehensive questionnaires, field audits, and GIS were used to measure the CBE variables and PV of 892 street segments on eight Chinese campuses in Tianjin.

Characteristics of blood-brain barrier heterogeneity between brain regions revealed by profiling vascular and perivascular cells.

The blood-brain barrier (BBB) protects the brain and maintains neuronal homeostasis. BBB properties can vary between brain regions to support regional functions, yet how BBB heterogeneity occurs is poorly understood. Here, we used single-cell and spatial transcriptomics to compare the mouse median eminence, one of the circumventricular organs that has naturally leaky blood vessels, with the cortex.

Exercise in patients with epilepsy and neurostimulation devices - physical activity levels, barriers, and beliefs.

Exercise improves many comorbidities associated with epilepsy in addition to seizure control. Despite the ILAE consensus statement noting the positive effects of exercise in patients with epilepsy (PWE) and individual assessment of risks pertaining to these activities, many healthcare professionals, including neurologists, are unfamiliar with these guidelines. Neurostimulation is an increasingly prevalent treatment option for refractory epilepsy.

Mass spectrometry-based proteomics for advancing solid organ transplantation research.

Scarcity of high-quality organs, suboptimal organ quality assessment, unsatisfactory pre-implantation procedures, and poor long-term organ and patient survival are the main challenges currently faced by the solid organ transplant (SOT) field. New biomarkers for assessing graft quality pre-implantation, detecting, and predicting graft injury, rejection, dysfunction, and survival are critical to provide clinicians with invaluable prediction tools and guidance for personalized patients' treatment. Additionally, new therapeutic targets are also needed to reduce injury and rejection and improve transplant outcomes.

Paraplegic Patient with Metastatic Papillary Thyroid Cancer: A Multidisciplinary Approach to Radioactive Iodine Therapy Safety and Efficacy Strategy.
