Centenarians-the way to healthy vascular ageing and longevity: a review from VascAgeNet.

The prevalence of centenarians, people who lived 100 years and longer, is steadily growing in the last decades. This exceptional longevity is based on multifaceted processes influenced by a combination of intrinsic and extrinsic factors such as sex, (epi-)genetic factors, gut microbiota, cellular metabolism, exposure to oxidative stress, immune status, cardiovascular risk factors, environmental factors, and lifestyle behavior. Epidemiologically, the incidence rate of cardiovascular diseases is reduced in healthy centenarians along with late onset of age-related diseases compared with the general aged population.

Impaired HBsAg release and antiproliferative/antioxidant cell regulation by HBeAg-negative patient isolates reflects an evolutionary process.

Background: The hepatitis B e antigen (HBeAg)-negative infection Phase 3 is characterized by no or minimal signs of hepatic inflammation and the absence of hepatic fibrosis. However, underlying molecular mechanisms leading to this benign phenotype are poorly understood.

Methods: Genotype A, B and D HBeAg-negative patient isolates with precore mutation G1896A from Phase 3 were analysed in comparison with respective HBeAg-positive rescue mutant and HBeAg-positive wild-type reference genomes regarding differences in viral replication, morphogenesis, infectivity and impact on NF-E2-related factor 2 (Nrf2)/antioxidant response element (ARE)-dependent gene expression and cellular kinome.

Integration of medical legal services into a hospital-based violence intervention program: A survey and interview-based provider needs assessment.

Background: Violent injury among trauma surgery patients is strongly associated with exposure to harmful social determinants of health and negative long-term health outcomes. Medical-legal partnerships in other settings successfully provide patients with legal services to address similar health-harming legal needs and may offer a promising model for the care of violently injured patients.

Study Design: An electronic survey tool was distributed to clinicians and staff affiliated with the hospital-based violence intervention program at a single urban level one trauma center.

Protocol for the induction of innate immune memory in human smooth muscle cells and endothelial cells in vitro.

Non-immune cells, like innate immune cells, can develop a memory-like phenotype in response to priming with microbial compounds or certain metabolites, which enables an enhanced response to a secondary unspecific stimulus. This paper describes a step-by-step protocol for the induction and analysis of trained immunity in human endothelial and smooth muscle cells. We then describe steps for cell culture with cryopreserved vascular cells, subcultivation, and induction of trained immunity.

Addressing Legal Needs as Violence Prevention: A National Survey of Legal Services Offered through Hospital-based Violence Intervention Programs.

Hospital-based violence intervention programs (HVIPs) provide comprehensive services to survivors of community violence to address social determinants of health (SDOH) as risks factors for future violence. Medical-legal partnerships (MLPs) integrate lawyers into health care teams to address SDOH through the application of the law. Despite shared purposes, it is unknown if HVIP-MLPs exist.

Law Enforcement and Patient Privacy Among Survivors of Violence: A Nationwide Mixed-Methods Study.

Introduction: During the emergent treatment of violently injured patients, law enforcement (LE) officers and health care providers frequently interact. Both have duties to protect patient health, rights, and public health, however, the balance of these duties may feel at odds. The purpose of this study is to assess hospital-based violence intervention program (HVIP) representatives' experiences with LE officers among survivors of violence and the impact of hospital policies on interactions with LE officers.

Healthcare Provider Engagement with a Novel Dashboard for Tracking Medication Ingestion: Impact on Treatment Decisions and Clinical Assessments for Adults with Schizophrenia.

Purpose: Schizophrenia is a severe, chronic condition accounting for disproportionate healthcare utilization. Antipsychotics can reduce relapse rates, but the characteristics of schizophrenia may hinder medication adherence. A phase 3b open-label clinical trial used aripiprazole tablets with sensor (AS; includes pills with ingestible event-marker, wearable sensor patches and smartphone application) in adults with schizophrenia.

LXRα Regulates oxLDL-Induced Trained Immunity in Macrophages.

Reprogramming of metabolic pathways in monocytes and macrophages can induce a proatherosclerotic inflammatory memory called trained innate immunity. Here, we have analyzed the role of the Liver X receptor (LXR), a crucial regulator of metabolism and inflammation, in oxidized low-density lipoprotein (oxLDL)-induced trained innate immunity. Human monocytes were incubated with LXR agonists, antagonists, and oxLDL for 24 h.

Health Effects of Policing in Hospitals: a Narrative Review.

Importance: Law enforcement activity, in the form of outside agencies or hospital security forces, is increasingly common in American healthcare. Little is known about the potential effects of this prevalent, modifiable exposure on hospital staff and patient health. This narrative review characterizes existing evidence on the direct and indirect health effects of law enforcement activity in hospitals.

Beyond the tracked line of sight - Evaluation of the peripheral usable field of view in a simulator setting.

Combining advanced gaze tracking systems with the latest vehicle environment sensors opens up new fields of applications for driver assistance. Gaze tracking enables researchers to determine the location of a fixation, and under consideration of the visual saliency of the scene, to predict visual perception of objects. The perceptual limits, for stimulus identification, found in literature have mostly been determined in laboratory conditions using isolated stimuli, with a fixed gaze point, on a single screen with limited coverage of the field of view.

Weathering Plastics as a Planetary Boundary Threat: Exposure, Fate, and Hazards.

We described in 2017 how weathering plastic litter in the marine environment fulfils two of three criteria to impose a planetary boundary threat related to "chemical pollution and the release of novel entities": (1) planetary-scale exposure, which (2) is not readily reversible. Whether marine plastics meet the third criterion, (3) eliciting a disruptive impact on vital earth system processes, was uncertain. Since then, several important discoveries have been made to motivate a re-evaluation.

Evaluating the impact of stay-at-home orders on the time to reach the peak burden of Covid-19 cases and deaths: does timing matter?

Background: The economic, psychological, and social impact of pandemics and social distancing measures prompt the urgent need to determine the efficacy of non-pharmaceutical interventions (NPIs), especially those considered most stringent such as stay-at-home and self-isolation mandates. This study focuses specifically on the impact of stay-at-home orders, both nationally and internationally, on the control of COVID-19.

Methods: We conducted an observational analysis from April to May 2020 and included both countries and US states with known stay-at-home orders.

Stability Series for the Complexation of Six Key Siderophore Functional Groups with Uranyl Using Density Functional Theory.

Determining stability constants of uranyl complexes with the principal functional groups in siderophores and identifying stability series is of great importance to predict which siderophore classes preferentially bind to U and, hence, impact uranium speciation in the environment. It also helps to develop resins for scavenging U from aqueous solutions. Here, we apply a recently developed computational approach to calculate log β values for a set of geochemically relevant uranium organometallic complexes using Density Functional Theory (DFT).

Support for Aggressive Tobacco Control Interventions Among California Adolescents and Young Adults.

Purpose: The aim of the study was to assess adolescent and young adult support for banning the sale of various tobacco and marijuana products and describe whether support varies by tobacco or marijuana use status.

Methods: We analyzed data from a California school-based survey (N = 450) on tobacco access, perceptions, social norms, marketing, and use.

Results: We found a majority of respondents favored gradually banning the sale of cigarettes (76%); e-cigarettes other than JUULs (55%); JUULs (59%); cigars, cigarillos, and little cigars (70%); and hookah (54%).

Pharmacokinetics and safety of deltoid or gluteal injection of aripiprazole lauroxil NanoCrystal Dispersion used for initiation of the long-acting antipsychotic aripiprazole lauroxil.

Background: Aripiprazole lauroxil (AL), a long-acting injectable antipsychotic for the treatment of schizophrenia in adults, can be started with either 21 days of daily oral aripiprazole supplementation or a 1-day initiation regimen consisting of a single injection of a NanoCrystal Dispersion formulation of AL (AL) and a single dose of 30 mg oral aripiprazole. This phase I study assessed the pharmacokinetics and safety of deltoid gluteal AL injections.

Methods: Patients with schizophrenia or schizoaffective disorder ( = 47) were randomized 1:1 to receive a single intramuscular dose of AL in the deltoid or gluteal muscle.

Computational Tools for Calculating log β Values of Geochemically Relevant Uranium Organometallic Complexes.

Uranium (U) interacts with organic ligands, subsequently controlling its aqueous chemistry. It is therefore imperative to assess the binding ability of natural organic molecules. We evidence that density functional theory (DFT) can be used as a practical protocol for predicting the stability of U organic ligand complexes, allowing for the development of a relative stability series for organic complexes with limited experimental data.

Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background.

The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitational waves. While general relativity allows for only two tensor gravitational-wave polarizations, general metric theories can additionally predict two vector and two scalar polarizations. The polarization of gravitational waves is encoded in the spectral shape of the stochastic gravitational-wave background, formed by the superposition of cosmological and individually unresolved astrophysical sources.

GW170817: Implications for the Stochastic Gravitational-Wave Background from Compact Binary Coalescences.

The LIGO Scientific and Virgo Collaborations have announced the event GW170817, the first detection of gravitational waves from the coalescence of two neutron stars. The merger rate of binary neutron stars estimated from this event suggests that distant, unresolvable binary neutron stars create a significant astrophysical stochastic gravitational-wave background. The binary neutron star component will add to the contribution from binary black holes, increasing the amplitude of the total astrophysical background relative to previous expectations.

GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral.

On August 17, 2017 at 12∶41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was detected with a combined signal-to-noise ratio of 32.4 and a false-alarm-rate estimate of less than one per 8.

GW170814: A Three-Detector Observation of Gravitational Waves from a Binary Black Hole Coalescence.

On August 14, 2017 at 10∶30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes, with a false-alarm rate of ≲1 in 27 000 years. The signal was observed with a three-detector network matched-filter signal-to-noise ratio of 18. The inferred masses of the initial black holes are 30.

Protein kinase enzymes in the human vagina-relation to key mediators of the cyclic AMP and cyclic GMP pathways.

Aside from phosphodiesterase (PDE) isoenzymes, protein kinases (cAK=cyclic AMP-binding protein kinase, cGK=cyclic GMP-binding protein kinase) have also been identified as important receptors for cyclic nucleotides. A significance of protein kinases in the control of the function of the male and female reproductive tract has been suggested; however, up until today, only a few approaches have addressed these enzymes in female genital tissues. The present study aimed to investigate by means of biochemical and immunohistochemical methods the expression of cAK and cGK.

Effects of endopeptidase inhibition on the relaxation response of isolated human penile erectile tissue to vasoactive peptides.

Peptides, such as CNP, CGRP and VIP, are involved in the function of male penile erectile tissue. Tissue levels of said peptides are controlled by the endopeptidase enzymes. Theoretically, the inhibition of the degradation of CNP, CGRP and/or VIP should result in an enhancement in penile smooth muscle relaxation.
