A network analysis of clinician-rated posttraumatic stress disorder and substance use disorder symptom clusters in a sample of veterans seeking outpatient treatment.

The presentation of comorbid post-traumatic stress disorder (PTSD) and substance use disorder (SUD) differs by substance type. The current study applied network analysis to explore the relationships between diagnostic symptom clusters by examining the strength and direction of unique associations between PTSD and SUD. Network analyses were estimated using a sample of 422 veterans diagnosed with co-occurring PTSD/SUD initiating psychotherapy for PTSD while receiving concurrent outpatient SUD treatment as part of a randomized clinical trial.

A landscape review to identify what matters to patients with thrombotic cardiovascular diseases and patient-reported outcome instruments which can be used to capture the patient experience.

Purpose: Thrombotic cardiovascular diseases profoundly impact patients' health-related quality of life (HRQoL). However, patient-reported outcome (PRO) instruments that are disease-specific or antithrombotic-treatment focused, developed according to US Food and Drug Administration (FDA) guidance on PROs, and can be used in clinical trials, are lacking. The aim of this study was to understand concepts important to patients diagnosed with coronary artery disease (CAD) or acute coronary syndrome (ACS), atrial fibrillation (AF), or stroke who require antithrombotic treatment for reducing risk of future thrombotic events (indications being evaluated for an investigational new drug), identify PROs that measure relevant symptoms and impacts, and determine acceptability of PROs from a health technology assessment (HTA) perspective.

Structure Determination of Zinc and Cadmium Dication Complexes with Intact and Deprotonated Histidyl Glycine and Glycyl Histidine Dipeptides.

Metalated intact and deprotonated histidyl glycine and glycyl histidine dipeptides were investigated in the gas phase by using infrared multiple photon dissociation (IRMPD) spectroscopy with light from a free-electron laser (FEL). The dipeptides M(GlyHis), M(HisGly), [M(GlyHis-H)], and [M(HisGly-H)], where M = Zn and Cd, were probed to elucidate how the His position along the peptide chain and ligand charge state might influence the structures observed in the gas phase. Simulated annealing calculations were performed to determine energetically low-lying conformers and isomers of these structures.

A comprehensive proteogenomic pipeline for neoantigen discovery to advance personalized cancer immunotherapy.

The accurate identification and prioritization of antigenic peptides is crucial for the development of personalized cancer immunotherapies. Publicly available pipelines to predict clinical neoantigens do not allow direct integration of mass spectrometry immunopeptidomics data, which can uncover antigenic peptides derived from various canonical and noncanonical sources. To address this, we present an end-to-end clinical proteogenomic pipeline, called NeoDisc, that combines state-of-the-art publicly available and in-house software for immunopeptidomics, genomics and transcriptomics with in silico tools for the identification, prediction and prioritization of tumor-specific and immunogenic antigens from multiple sources, including neoantigens, viral antigens, high-confidence tumor-specific antigens and tumor-specific noncanonical antigens.

Enthalpy of the Cerium (Ce) Chemi-Ionization Reaction and CeO, CeC, and CeCO Bond Energies Determined by Energy-Resolved Guided Ion Beam Mass Spectrometry Experiments.

Cerium (Ce) oxide, carbide, and carbonyl cation bond energies and the exothermicity of the Ce chemi-ionization (CI) reaction with atomic oxygen were investigated using guided-ion beam tandem mass spectrometry (GIBMS). The kinetic energy dependent product cross sections for reactions of Ce with O, CO, and CO and CeO with O, CO, Xe, and Ar were measured using GIBMS. For the reactions of Ce with O and CO, CeO is formed through an exothermic reaction, whereas CeO formation is endothermic in the reaction with CO.

Inclusion of Trainee Stakeholders Is Necessary for Effective Change in Health-Service-Psychology Internship Training.

In a recent call to action, we described pressing issues in the health-service-psychology (HSP) internship from the perspective of interns. In our article, we sought to initiate a dialogue that would include trainees and bring about concrete changes. The commentaries on our article are a testament to the readiness of the field to engage in such a dialogue, and we applaud the actionable recommendations that they make.

DnaA modulates the gene expression and morphology of the Lyme disease spirochete.

All bacteria encode a multifunctional DNA-binding protein, DnaA, which initiates chromosomal replication. Despite having the most complex, segmented bacterial genome, little is known about DnaA and its role in maintaining the spirochete's physiology. In this work we utilized inducible CRISPR-interference and overexpression to modulate cellular levels of DnaA to better understand this essential protein.

An Opt-out Tobacco Treatment Group Intervention Within an Intensive Substance Use Disorders Treatment Program: Initial Outcomes in the Veterans Health Administration.

Introduction: Despite steadily declining rates of tobacco use in the United States, individuals suffering from substance use disorders (SUD) and other mental illnesses continue to use tobacco at alarmingly high rates, resulting in increased mortality. Given the synergistic consequences to those who suffer from both tobacco use disorders (TUD) and other SUD, embedding tobacco treatment into structured SUD programs using an opt-out approach may yield a greater impact. The current study compares clinical outcomes (ie, quit attempts and prescription of tobacco cessation medications) for an opt-out versus opt-in approach to tobacco treatment.

Difficulties in using land use pressure and soil quality indicators to predict water quality.

Intensive agriculture can impair river water quality. Soil quality monitoring has been used to measure the effect of land use intensification on water quality at a point and field scales but not at the catchment scale. Other farm scale land use pressures, like stocking rate and the value of land, which relate to land use intensity are now publicly available, nationally.

ARID1A suppresses R-loop-mediated STING-type I interferon pathway activation of anti-tumor immunity.

Clinical trials have identified ARID1A mutations as enriched among patients who respond favorably to immune checkpoint blockade (ICB) in several solid tumor types independent of microsatellite instability. We show that ARID1A loss in murine models is sufficient to induce anti-tumor immune phenotypes observed in ARID1A mutant human cancers, including increased CD8+ T cell infiltration and cytolytic activity. ARID1A-deficient cancers upregulated an interferon (IFN) gene expression signature, the ARID1A-IFN signature, associated with increased R-loops and cytosolic single-stranded DNA (ssDNA).

Kinetic energy dependence and potential energy surface of the spin-forbidden reaction Sm+ (8F) + N2O (1Σ+) → SmO+ (6Δ) + N2 (1Σg+).

The kinetic energy dependence of the title reaction is examined using guided ion beam tandem mass spectrometry. Because this reaction is spin-forbidden, crossings between octet and sextet hypersurfaces presumably must occur. Furthermore, Sm+ must transition from a 4f66s1 configuration in the reactant to 4f55d2 in order to have the orbital occupancy required to form the triple bond in SmO+ (6Δ).

Temporarily Reversing Warfarin With Low-Dose 4-Factor Prothrombin Complex Concentrate in Left Ventricular Assist Device Patients Undergoing an Invasive Procedure.

Background: American Association for Thoracic Surgery and The International Society for Heart and Lung Transplantation (AATS/ISHLT) guidelines recommend warfarin in patients with continuous-flow left ventricular assist devices (LVADs) to reduce the risk of device thrombosis and systemic embolization. Left ventricular assist device patients often undergo elective and emergent procedures that require interrupted anticoagulation. Data and experience vary on the optimal strategy to rapidly reverse warfarin in LVAD patients when an emergent procedure is planned.

The bond energy of UN+: Guided ion beam studies of the reactions of U+ with N2 and NO.

A guided ion beam tandem mass spectrometer was used to study the reactions of U+ with N2 and NO. Reaction cross sections were measured over a wide range of energy for both systems. In each reaction, UN+ is formed by an endothermic process, thereby enabling the direct measurement of the threshold energy and determination of the UN+ bond dissociation energy.

Spatial connectivity of reef manta rays across the Raja Ampat archipelago, Indonesia.

The reef manta ray is present throughout most island groups that form the Raja Ampat archipelago, Indonesia. The species is protected regionally and nationally and is currently managed as a single homogeneous population within the 6.7 million ha archipelago.

(S)-S-adenosylmethionine in the treatment of pre-menstrual disorders in adult women: A protocol for an open-label pilot study.

Pre-menstrual disorders, including pre-menstrual syndrome and pre-menstrual dysphoric disorder, are highly prevalent disorders in women of reproductive age. Pre-menstrual disorders are associated with debilitating symptoms that onset in the days prior to menses. A complex interplay between hormonal fluctuations, cellular sensitivity, and psychosocial stressors likely underly the pathophysiology of pre-menstrual disorders.

IR spectroscopic characterization of [M,C,2H] (M = Ru and Rh) products formed by reacting 4d transition metal cations with oxirane: Spectroscopic evidence for multireference character in RhCH.

A combination of infrared multiple-photon dissociation (IRMPD) action spectroscopy and quantum chemical calculations was employed to investigate the [M,C,2H] (M = Ru and Rh) species. These ions were formed by reacting laser ablated M ions with oxirane (ethylene oxide, c-CHO) in a room-temperature ion trap. IRMPD spectra for the Ru species exhibit one major band and two side bands, whereas spectra for the Rh species contain more distinct bands.

Borrelia burgdorferi PlzA is a cyclic-di-GMP dependent DNA and RNA binding protein.

The PilZ domain-containing protein, PlzA, is the only known cyclic di-GMP binding protein encoded by all Lyme disease spirochetes. PlzA has been implicated in the regulation of many borrelial processes, but the effector mechanism of PlzA was not previously known. Here, we report that PlzA can bind DNA and RNA and that nucleic acid binding requires c-di-GMP, with the affinity of PlzA for nucleic acids increasing as concentrations of c-di-GMP were increased.

Immunopeptidomics-based identification of naturally presented non-canonical circRNA-derived peptides.

Circular RNAs (circRNAs) are covalently closed non-coding RNAs lacking the 5' cap and the poly-A tail. Nevertheless, it has been demonstrated that certain circRNAs can undergo active translation. Therefore, aberrantly expressed circRNAs in human cancers could be an unexplored source of tumor-specific antigens, potentially mediating anti-tumor T cell responses.

The Role of β-Dystroglycan in Nuclear Dynamics.

Dystroglycan is a ubiquitously expressed heterodimeric cell-surface laminin receptor with roles in cell adhesion, signalling, and membrane stabilisation. More recently, the transmembrane β-subunit of dystroglycan has been shown to localise to both the nuclear envelope and the nucleoplasm. This has led to the hypothesis that dystroglycan may have a structural role at the nuclear envelope analogous to its role at the plasma membrane.

A flexible framework for spatial capture-recapture with unknown identities.

Camera traps or acoustic recorders are often used to sample wildlife populations. When animals can be individually identified, these data can be used with spatial capture-recapture (SCR) methods to assess populations. However, obtaining animal identities is often labor-intensive and not always possible for all detected animals.

That's not the Mona Lisa! How to interpret spatial capture-recapture density surface estimates.

Spatial capture-recapture methods are often used to produce density surfaces, and these surfaces are often misinterpreted. In particular, spatial change in density is confused with spatial change in uncertainty about density. We illustrate correct and incorrect inference visually by treating a grayscale image of the Mona Lisa as an activity center intensity or density surface and simulating spatial capture-recapture survey data from it.
