Background: Cytomegalovirus (CMV) mismatched, donor IgG-positive/recipient IgG-negative, solid organ transplant recipients (SOTRs) are at high risk of CMV invasive disease. Post-prophylaxis disease is an issue in this population. Some programs employ surveillance after prophylaxis (SAP) to limit the incidence of post-prophylaxis disease.

Researchers have examined civic engagement as a health promotion tool among older adults and adolescents, yet less is known about its mental health implications for young adults. This systematic review identified 53 articles on civic engagement and well-being in young adults. Five key themes emerged: (1) varying associations between type of civic engagement and well-being, (2) duration and frequency of civic behaviors, (3) directionality in the civic-to-well-being pathway, (4) mediation and moderation factors affecting the civic-to-well-being pathway, and (5) civic engagement as a tool for coping with adversity or systemic oppression.

Vaping is common among young adults in the United States. The Transtheoretical Model (TTM) has demonstrated success in smoking cessation efforts; however, it has not been comprehensively applied to vaping cessation, and core TTM vaping measures have not been developed. A cross-sectional survey including measures of stage of change (SOC), temptation to vape, and decisional balance (DCBL) was disseminated ( = 459).

Medical care received at end-of-life is often not aligned with individuals' values and care preferences. Much can get in the way of an individual communicating and documenting their preferences to care providers and close others, even if it is a goal to do so. The objective of this work was to develop a measure of Advance Care Planning Self-Efficacy (ACP SE) focused on three important behaviors: completing a living will, documenting a healthcare agent, and discussing quality versus quantity of life issues.

A bonded particle model is used to explore how variations in the material properties of brittle, isotropic solids affect critical behavior in fragmentation. To control material properties, a model is proposed which includes breakable two- and three-body particle interactions to calibrate elastic moduli and mode I and mode II fracture toughnesses. In the quasistatic limit, fragmentation leads to a power-law distribution of grain sizes which is truncated at a maximum grain mass that grows as a nontrivial power of system size.

Purpose: In the United States (US), individuals vary widely in their readiness to get vaccinated for COVID-19. The present study developed measures based on the transtheoretical model (TTM) to better understand readiness, decisional balance (DCBL; pros and cons), self-efficacy (SE), as well as other motivators for change such as myths and barriers for COVID-19 vaccination.

Design: Cross-sectional measurement development.

Young adults may benefit from civic engagement as a health promotion tool, as civic engagement is generally associated with positive well-being. However, more information is needed to examine civic engagement among lesser-educated young adults who are least likely to civically engage, and more likely to demonstrate mental health needs. We surveyed noncollege young adults (N = 621) to measure their civic engagement, meaning, civic efficacy, well-being, and sociodemographic factors.

The tangential force required to observe slip across a whole frictional interface can increase over time under a constant load, due to any combination of creep, chemical, or structural changes of the interface. In macroscopic rate-and-state models, these frictional aging processes are lumped into an ad hoc state variable. Here we explain, for a frictional system exclusively undergoing structural aging, how the macroscopic friction response emerges from the interplay between the surface roughness and the molecular motion within adsorbed monolayers.

Studies of natural hybrid zones can provide documentation of range shifts in response to climate change and identify loci important to reproductive isolation. Using a temporal (36-38 years) comparison of the black-capped (Poecile atricapillus) and Carolina (P. carolinensis) chickadee hybrid zone, we investigated movement of the western portion of the zone (western Missouri) and assessed whether loci and pathways underpinning reproductive isolation were similar to those in the eastern portion of the hybrid zone.

Using two-dimensional simulations of sheared, brittle solids, we characterize the resulting fragmentation and explore its underlying critical nature. Under quasistatic loading, a power-law distribution of fragment masses emerges after fracture which grows with increasing strain. With increasing strain rate, the maximum size of a grain decreases and a shallower distribution is produced.

  • Influenza B can lead to rare cases of cardiogenic shock, as demonstrated by a patient without pre-existing heart disease who developed myocarditis.
  • The patient's condition worsened, resulting in complications such as rhabdomyolysis, compartment syndrome, renal failure, and pneumonia.
  • Successful treatment included Oseltamivir, renal replacement therapy, antimicrobials, and intubation, highlighting the need for prompt recognition and management of such cases.

Purpose This article is the first in a two-part series on the application of the to stuttering management among adolescents. In this article, we describe the process of developing measures to assess stage of change (SOC) by defining behaviors of stuttering management, as well as the two primary cognitive constructs that underlie one's readiness to make behavioral change: decisional balance (DB) and situational self-efficacy (SSE). This work hinges on the ability to develop an operational definition of what it means to successfully manage or do something positive about one's stuttering.

Interprofessional education (IPE) has been promoted as one way to prepare healthcare students for interprofessional encounters they might experience in the workplace. However, the link between IPE, interprofessional care in the workforce, and better patient outcomes is tenuous, perhaps in part due to the inability of IPE programs to adequately address barriers associated with interprofessional care (e.g.

Purpose: Engaging in community service, or unpaid work intended to help people in a community, is generally associated with greater overall well-being. However, the process of beginning and maintaining community service engagement has been sparsely examined. The current study applied the Transtheoretical Model (TTM) of behavior change to understanding community service readiness among young adults.

Resolving atomic scale details while capturing long-range elastic deformation is the principal difficulty when solving contact mechanics problems with computer simulations. Fully atomistic simulations must consider large blocks of atoms to support long-wavelength deformation modes, meaning that most atoms are far removed from the region of interest. Building on earlier methods that used elastic surface Green's functions to compute static substrate deformation, we present a numerically efficient dynamic Green's function technique to treat realistic, time-evolving, elastic solids.

Disordered solids respond to quasistatic shear with intermittent avalanches of plastic activity, an example of the crackling noise observed in many nonequilibrium critical systems. The temporal power spectrum of activity within disordered solids consists of three distinct domains: a novel power-law rise with frequency at low frequencies indicating anticorrelation, white-noise at intermediate frequencies, and a power-law decay at high frequencies. As the strain rate increases, the white-noise regime shrinks and ultimately disappears as the finite strain rate restricts the maximum size of an avalanche.

Rate effects in sheared disordered solids are studied using molecular dynamics simulations of binary Lennard-Jones glasses in two and three dimensions. In the quasistatic (QS) regime, systems exhibit critical behavior: the magnitudes of avalanches are power-law distributed with a maximum cutoff that diverges with increasing system size L. With increasing rate, systems move away from the critical yielding point and the average flow stress rises as a power of the strain rate with exponent 1/β, the Herschel-Bulkley exponent.
