Author(s): Daniel J. Becker, Kelly A. Speer, Alexis M. Brown, M. Brock Fenton, Alex D. Washburne, Sonia Altizer, Daniel G. Streicker, Raina K. Plowright, Vladimir E. Chizhikov, Nancy B. Simmons, Dmitriy V. Volokhov

Publication:  Molecular Ecology

Background/Purpose: Most emerging pathogens can infect multiple species, underscoring the importance of understanding the ecological and evolutionary factors that allow some hosts to harbor greater infection prevalence and share pathogens with other species. However, our understanding of pathogen jumps is primarily based around viruses, despite bacteria accounting for the greatest proportion of zoonoses.

Ensuring and sustaining a pandemic workforce

Author(s): Erin P. Fraher, Patricia Pittman, Bianca K. Frogner, Joanne Spetz, Jean Moore, Angela J. Beck, David Armstrong, Peter I. Buerhaus

Publication: The New England Journal of Medicine

Background/Purpose: Current efforts to fight the Covid-19 pandemic aim to slow viral spread and increase testing, protect health care workers from infection, and obtain ventilators and other equipment to prepare for a surge of critically ill patients. But additional actions are needed to rapidly increase health workforce capacity and to replenish it when personnel are quarantined or need time off to rest or care for sick family members.


Subjective and objective sleep differ in male and female collegiate athletes

Author(s): Jason R. Carter, Brett M. Gervais, Janelle L. Adomeit, Ian M. Greenlund

Publication: Sleep Health

Background/Purpose: Despite the importance of sleep for athletic performance, there is a lack of normative sleep data and sex comparisons in collegiate athletes. The primary purpose of our study was to assess the prevalence of insufficient sleep in collegiate athletes, with a secondary aim to compare male and female athletes.


Cardiovascular disease in women across the lifespan: the importance of sleep

Author(s): Stacie L. Daugherty, Jason R. Carter, Ghada Bourjeily

Publication: Journal of Women's Health

Background/Purpose: The proposed pathways linking sleep disturbances and adverse cardiovascular outcomes in women are numerous and the complex interaction between them is not well understood. Future research focused on understanding the scope of sleep disorders in women, defining the underlying mechanisms, and testing interventions to improve sleep are critical for improving the cardiovascular health of all women.


The UCLA PTSD reaction index for DSM-5 brief form: a screening tool for trauma-exposed youths

Author(s): Benjamin Rolon-Arroyo, Benjamin Oosterhoff, Christopher M. Layne, Alan M. Steinberg, Robert S. Pynoos, Julie B. Kaplow

Publication: Journal of the American Academy of Child & Adolescent Psychiatry

Background/Purpose: Children and adolescents who experience potentially traumatic events are at risk for developing posttraumatic stress disorder (PTSD). Although psychometrically sound measures are now available to assess these youths, brief tools are currently needed for screening purposes.


No longer an island: a social network intervention engaging black men through CBPR

Author(s): Amy E. Harley, David Frazer, Tyler Weber, Terron C. Edwards, Nicole Carnegie

Publication: American Journal of Men's Health

Background/Purpose: The aim of this study was to assess outcomes from a multilevel social network intervention to promote the health of Black men. Through a community–academic collaboration and using a participatory research approach, we implemented the intervention over 4 years in a 110-block area of an urban neighborhood. The project aimed to implement a neighborhood peer outreach and leadership network to strengthen social support of Black men and increase community and family engagement.


The origin of extracellular DNA in bacterial biofilm infections in vivo

Author(s): Maria Alhede, Morten Alhede, Klaus Qvortrup, Kasper Norskov Kragh, Peter Ostrup Jensen, Philip Shook Stewart, Thomas Bjarnsholt

Publication: Pathogens and Disease

Background/Purpose: Extracellular DNA (eDNA) plays an important role in both the aggregation of bacteria and in the interaction of the resulting biofilms with polymorphonuclear leukocytes (PMNs) during an inflammatory response. Here, transmission electron and confocal scanning laser microscopy were used to examine the interaction between biofilms of Pseudomonas aeruginosa and PMNs in a murine implant model and in lung tissue from chronically infected cystic fibrosis patients.


Risk factors for chronic biofilm-related infection associated with implanted medical devices

Author(s): Philip S. Stewart, Thomas Bjarnsholt

Publication: Clinical Microbiology and Infection

Background/Purpose: Why do some patients develop chronic infection associated with an implanted device, but most do not? Objectives The literature on patient-specific risk factors for chronic infections associated with five types of implants was surveyed to glean clues about the etiology of these infections.


Implications of the rapid growth of the nurse practitioner workforce in the US

Author(s): David I. Auerbach, Peter I. Buerhaus, Douglas O. Staiger

Publication: Health Affairs

Background/Purpose: Concerns about physician shortages have led policy makers in the US public and private sectors to advocate for the greater use of nurse practitioners (NPs). We examined recent changes in demographic, employment, and earnings characteristics of NPs and the implications of those changes.


A new twist on the graduate student journal club: using a topic-centered approach to promote student engagement

Author(s): Diane Bimczok, John Graves

Publication: Biochemistry and Molecular Biology Education

Background/Purpose: Journal clubs are widely used as an educational tool in graduate life science programs. In journal clubs, students are assigned to read specific journal articles to achieve a broad knowledge in their field of study and to gain competence in reading and assessing scientific publications.


Historical trends in concerns about social issues across four decades among US adolescents

Author(s): Benjamin Oosterhoff, Laura Wray-Lake, Cara A. Palmer, Julie B. Kaplow

Publication: Journal of Research on Adolescence

Background/Purpose: This study examined adolescents’ concerns about social issues and how these concerns have changed over historical time.


Macroimmunology: the drivers and consequences of spatial patterns in wildlife immune defense

Author(s): Daniel J. Becker, Gregory F. Albery, Maureen K. Kessler, Tamika J. Lunn, Caylee A. Falvo, Gabor A. Czirjak, Lynn B. Martin, Raina K. Plowright

Publication: Journal of Animal Ecology

Background/Purpose: The prevalence and intensity of parasites in wild hosts varies across space and is a key determinant of infection risk in humans, domestic animals and threatened wildlife. Because the immune system serves as the primary barrier to infection, replication and transmission following exposure, we here consider the environmental drivers of immunity.


Do uncivil nursing students become uncivil nurses? A national survey of faculty

Author(s): Susan Luparell, Kristi Frisbee

Publication: Nursing Education Perspectives

Background/Purpose: The purpose of this study was to determine what knowledge faculty have of poorly behaving nursing students who also behaved poorly in subsequent practice.

Background/Purpose: This study sought to evaluate the evidence for commonly employed topical agents used in wounds for the purpose of treating chronic infections caused by biofilm.


Synchronous shedding of multiple bat paramyxoviruses coincides with peak periods of Hendra virus spillover

Author(s): Alison J. Peel, Konstans Wells, John Giles, Victoria Boyd, Amy Burroughs, Daniel Edson, Gary Crameri, Michelle L. Baker, Hume Field, Lin-Fa Wang, Hamish McCallum, Raina K. Plowright, Nicholas Clark

Publication: Emerging Microbes & Infections

Background/Purpose: Within host-parasite communities, viral co-circulation and co-infections of hosts are the norm, yet studies of significant emerging zoonoses tend to focus on a single parasite species within the host. Using a multiplexed paramyxovirus bead-based PCR on urine samples from Australian flying foxes, we show that multi-viral shedding from flying fox populations is common.
