Healthy work environment: A systematic review informing a nursing professional practice model in the US Military Health System.

AIM: The aim of the study was to develop recommendations for creating a healthy work environment based on current literature for nurses working within the US Military Health System (MHS). However, our findings would likely benefit other nursing populations and environments as well. DESIGN: Systematic literature review. DATA SOURCES: We conducted a systematic literature search for articles published between January 2010 until January 2024 from five databases: PubMed, Joanna Briggs, Embase, CINAHL and Scopus. METHODS: Articles were screened, selected and extracted using Covidence software. Article findings were synthesized to create recommendations for the development, implementation and measurement of healthy work environments. RESULTS: Ultimately, a total of 110 articles met the criteria for inclusion in this review. The articles informed 13 recommendations for creating a healthy work environment. The recommendations included ensuring teamwork, mentorship, job satisfaction, supportive leadership, nurse recognition and adequate staffing and resources. Additionally, we identified strategies for implementing and measuring these recommendations. CONCLUSIONS: This thorough systematic review created actionable recommendations for the creation of a healthy work environment. Based on available evidence, implementation of these recommendations could improve nursing work environments. IMPACT: This study identifies methods for implementing and measuring aspects of a healthy work environment. Nurse leaders or others can implement the recommendations provided here to develop healthy work environments in their hospitals, clinics or other facilities where nurses practice. REPORTING METHOD: PRISMA 2020 guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

IMPAACT: IMproving the PArticipAtion of older people in policy decision-making on common health CondiTions - a study protocol.

INTRODUCTION: Rapid population ageing is a demographic trend being experienced and documented worldwide. While increased health screening and assessment may help mitigate the burden of illness in older people, issues such as misdiagnosis may affect access to interventions. This study aims to elicit the values and preferences of evidence-informed older people living in the community on early screening for common health conditions (cardiovascular disease, diabetes, dementia and frailty). The study will proceed in three Phases: (1) generating recommendations of older people through a series of Citizens' Juries; (2) obtaining feedback from a diverse range of stakeholder groups on the jury findings; and (3) co-designing a set of Knowledge Translation resources to facilitate implementation into research, policy and practice. Conditions were chosen to reflect common health conditions characterised by increasing prevalence with age, but which have been underexamined through a Citizens' Jury methodology. METHODS AND ANALYSIS: This study will be conducted in three Phases-(1) Citizens' Juries, (2) Policy Roundtables and (3) Production of Knowledge Translation resources. First, older people aged 50+ (n=80), including those from traditionally hard-to-reach and diverse groups, will be purposively recruited to four Citizen Juries. Second, representatives from a range of key stakeholder groups, including consumers and carers, health and aged care policymakers, general practitioners, practice nurses, geriatricians, allied health practitioners, pharmaceutical companies, private health insurers and community and aged care providers (n=40) will be purposively recruited for two Policy Roundtables. Finally, two researchers and six purposively recruited consumers will co-design Knowledge Translation resources. Thematic analysis will be performed on documentation and transcripts. ETHICS AND DISSEMINATION: Ethical approval has been obtained through the Torrens University Human Research Ethics Committee. Participants will give written informed consent. Findings will be disseminated through development of a policy brief and lay summary, peer-reviewed publications, conference presentations and seminars.

Development of a Joint Professional Practice Model for the Total Nursing Force of the United States Military: Describing an Evidence-Based Process Across Multiple Entities.

Professional practice models are a hallmark of professional organizations. Creating a model that can apply across contexts, however, can be a challenge. This article describes the process that a team of nurse leaders and researchers used to create a professional practice model that would serve active-duty and civilian nurses working in military treatment facilities.

Findings from the development of a nursing joint professional practice model for the U.S. military.

BACKGROUND: By 2022 the Defense Health Agency became responsible for administration of all military treatment facilities (MTFs), which were previously managed by their respective military services. However, three different service-specific nursing professional practice models currently govern nursing practice in MTFs. PURPOSE: To describe the literature search, review, and synthesis of evidence which informed the JPPM and provide some of the most actionable findings. METHODS: A team of tri-service nurses developed the JPPM by conducting six rigorous systematic reviews to synthesize evidence pertaining to relevant model components. DISCUSSION: A total of 51,360 titles and abstracts were initially screened. Data were extracted from 540 included articles. The team then developed standards for five JPPM components: evidence-based practice, safety and quality, leadership development, healthy work environment, and operational readiness. CONCLUSION: The JPPM is a meaningful framework that will help create a mutual professional identity and shared vision to promote a unified nursing force in U.S. military settings.

Components, Implementation, and Outcomes of a Nursing Professional Practice Model: A Systematic Review.

Nursing professional practice models (PPMs) are known to have beneficial effects on nurse and patient outcomes. Determining what components should be present in a PPM, how to implement a PPM, and evaluating the outcomes associated with a PPM is less certain. Therefore, as part of a larger project to develop a nursing PPM for use within the United States Military Health System, this study aimed to conduct a systematic literature review on nursing PPMs. Specifically, the review sought to investigate components, implementation, and outcomes of PPMs in current literature. A total of 37 articles were included in the review. The literature supported the development of 12 recommendations for creating, implementing, and evaluating a nursing PPM. As health care facilities develop their own PPMs or reassess their current PPMs, findings from this review may assist hospital leadership by providing the most recent evidence on the strategic value of nursing PPMs in contemporary health care.

IMP1/IGF2BP1 in human colorectal cancer extracellular vesicles.

Colorectal cancer (CRC) is a leading cause of cancer-related death. There is an urgent need for new methods of early CRC detection and monitoring to improve patient outcomes. Extracellular vesicles (EVs) are secreted, lipid-bilayer bound, nanoparticles that carry biological cargo throughout the body and in turn exhibit cancer-related biomarker potential. RNA binding proteins (RBPs) are posttranscriptional regulators of gene expression that may provide a link between host cell gene expression and EV phenotypes. Insulin-like growth factor 2 RNA binding protein 1 (IGF2BP1/IMP1) is an RBP that is highly expressed in CRC with higher levels of expression correlating with poor prognosis. IMP1 binds and potently regulates tumor-associated transcripts that may impact CRC EV phenotypes. Our objective was to test whether IMP1 expression levels impact EV secretion and/or cargo. We used RNA sequencing, in vitro CRC cell lines, ex vivo colonoid models, and xenograft mice to test the hypothesis that IMP1 influences EV secretion and/or cargo in human CRC. Our data demonstrate that IMP1 modulates the RNA expression of transcripts associated with extracellular vesicle pathway regulation, but it has no effect on EV secretion levels in vitro or in vivo. Rather, IMP1 appears to affect EV regulation by directly entering EVs in a transformation-dependent manner. These findings suggest that IMP1 has the ability to shape EV cargo in human CRC, which could serve as a diagnostic/prognostic circulating tumor biomarker.NEW & NOTEWORTHY This work demonstrates that the RNA binding protein IGF2BP1/IMP1 alters the transcript profile of colorectal cancer cell (CRC) mRNAs from extracellular vesicle (EV) pathways. IMP1 does not alter EV production or secretion in vitro or in vivo, but rather enters CRC cells where it may further impact EV cargo. Our work shows that IMP1 has the ability to shape EV cargo in human CRC, which could serve as a diagnostic/prognostic circulating tumor biomarker.

Sleep protocol-Use of evidence-based practice (EBP) to improve patient outcomes and patient satisfaction while hospitalized.

BACKGROUND: Anecdotal observation at a 55-bed training hospital indicated decreased patient satisfaction from patients not feeling rested during hospitalization related to staggered nighttime nursing care. AIMS: The main aim of this study is to implement a new culture of patient centeredness to enhance patient care and improve outcomes at a 34-bed Medical-Surgical Inpatient Unit (MSIU) within the training hospital. METHODS: An evidence-based practice approach was chosen to address the aim. This included the development of a PICOT (population, intervention, comparison, outcome, and time frame) question, a systematic search of the literature, a critical appraisal of the evidence, implementation of the intervention, evaluation of outcomes, and dissemination of the results. RESULTS: Twenty-three articles were critically appraised, resulting in 11 keeper articles. The body of evidence reviewed demonstrated that minimizing nighttime patient interruptions through bundled care could improve patient sleep, pain perception, and patient outcomes and reduce fatigue. Bundled care was implemented in the MSIU for 1 year. During this year, there was a significant reduction in hydrocodone administration, a notable reduction in prescription sleep aid administration, a 75% reduction in fall rates, a cost savings of $64,000, and a decrease in patient length of stay. LINKING EVIDENCE TO ACTION: Allowing patients to rest could have benefits. Rest improves outcomes, length of stay, satisfaction scores, and fall rates and reduces the need for medications. Clustering care allows patients to receive uninterrupted rest.

Introducing the American Society for Bone and Mineral Research multistakeholder group secondary fracture prevention recommendations: Nurse practitioners play an important role.

ABSTRACT: Sequelae after an osteoporosis-related fracture include significant morbidity and mortality. Preventing repeat fractures is an important aspect of mitigating these sequelae. As highlighted in the American Society for Bone and Mineral Research multistakeholder coalition's Secondary Fracture Prevention: Consensus Clinical Recommendations, nurse practitioners play an important role in secondary fracture prevention. With a focus on education, longitudinal relationships with patients, and expertise in coordinating and managing care, nurse practitioners are uniquely qualified to run Fracture Liaison Services and help close the gap to care in secondary fracture prevention.

Disciplinary Bias, Money Matters, and Persistence: Deans' Perspectives on Science Faculty with Education Specialties (SFES).

The phenomenon of embedding Science Faculty with Education Specialties (SFES) in science departments is well documented. However, the perspectives of academic leaders have not been systematically studied. To investigate these perspectives, we conducted an interview study of college of science deans in the California State University system, which offers a defined higher education context in which to sample across a range of institution types and cultures. While deans were aware of and positive about SFES as potential change agents, most deans also evidenced casual bias against science education efforts and experts. Deans mentioned that education reform efforts by SFES were primarily driven by external policy and funding mandates, causing concern that support for such positions and scholarly work could evaporate if external pressures recede. The majority of deans stated that the SFES phenomenon had persisted over the last decade and continued to grow. Findings reported here document tacit assumptions that science education efforts may not count as science and reveal a lack of cultural integration of science education efforts into the sciences in higher education. Such findings should give biology educators, reformers, and researchers pause, as well as fresh incentive to engage more fully and regularly with administrators about their work.

Efficacy of an Interdisciplinary Intensive Outpatient Program in Treating Combat-Related Traumatic Brain Injury and Psychological Health Conditions.

Background: Since 2000, over 413,000 US service members (SM) experienced at least one traumatic brain injury (TBI), and 40% of those with in-theater TBIs later screened positive for comorbid psychological health (PH) conditions, including post-traumatic stress disorder (PTSD), depression, and anxiety. Many SMs with these persistent symptoms fail to achieve a recovery that results in a desirable quality of life or return to full duty. Limited information exists though to guide treatment for SMs with a history of mild TBI (mTBI) and comorbid PH conditions. This report presents the methods and outcomes of an interdisciplinary intensive outpatient program (IOP) in the treatment of SMs with combat-related mTBI and PH comorbidities. The IOP combines conventional rehabilitation therapies and integrative medicine techniques with the goal of reducing morbidity in multiple neurological and behavioral health domains and enhancing military readiness. Methods: SMs (n = 1,456) with residual symptoms from mTBI and comorbid PH conditions were treated in a 4-week IOP at the National Intrepid Center of Excellence (NICoE) at Walter Reed National Military Medical Center (WRNMMC). The IOP uses an interdisciplinary, holistic, and patient-centric rehabilitative care model. Interdisciplinary teams provide a diagnostic workup of neurological, psychiatric, and existential injuries, and from these assessments, individualized care plans are developed. Treatment response was assessed using the Neurobehavioral Symptom Inventory (NSI), PTSD Checklist-Military Version (PCL-M), Satisfaction With Life Scale (SWLS), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Epworth Sleepiness Scale (ESS), and Headache Impact Test-6 (HIT-6) and administered at admission, discharge, and at 1, 3, and 6 months post-discharge. Findings: Following treatment in the IOP, the symptomatic patients had statistically significant and clinically meaningful improvements across all outcome measures. The largest effect size was seen with GAD-7 (r = 0.59), followed by PHQ-8 (r = 0.56), NSI (r = 0.55), PCL-M (r = 0.52), ESS (r = 0.50), SWLS (r = 0.49), and HIT-6 (r = 0.42). In cross-sectional follow ups, the significant improvements were sustained at 1, 3, and 6 months post-discharge. Interpretation: This report demonstrates that an interdisciplinary IOP achieves significant and sustainable symptom recovery in SMs with combat-related mTBI and comorbid PH conditions and supports the further study of this model of care in complex medical conditions.

"A Real Bucket of Worms": Views of People Living with Dementia and Family Members on Supported Decision-Making.

Supported decision-making has been promoted at a policy level and within international human rights treaties as a way of ensuring that people with disabilities enjoy the right to legal capacity on an equal basis with others. However, little is known about the practical issues associated with implementing supported decision-making, particularly in the context of dementia. This study aimed to understand the experiences of people with dementia and their family members with respect to decision-making and their views on supported decision-making. Thirty-six interviews (twenty-one dyadic and fifteen individual) were undertaken with fifty-seven participants (twenty-five people living with dementia and thirty-two family members) across three states in Australia. Interpretative Phenomenological Analysis (IPA) was used as the methodological approach, with relational autonomy as a theoretical perspective. We identified two overarching themes relating to participants' experiences with decision-making: "the person in relationship over time" and "maintaining involvement." Participant views on the practical issues associated with supported decision-making are addressed under the themes of "facilitating decision-making," "supported decision-making arrangements," "constraints on decision-making," and "safeguarding decision-making." While participants endorsed the principles of supported decision-making as part of their overarching strategy of "maintaining involvement" in decision-making, they recognized that progressive cognitive impairment meant that there was an inevitable transition toward greater involvement of, and reliance upon, others in decision-making. Social and contextual "constraints on decision-making" also impacted on the ability of people with dementia to maintain involvement. These themes inform our proposal for a "spectrum approach" to decision-making involvement among people living with dementia, along with recommendations for policy and practice to assist in the implementation of supported decision-making within this population.

Neurocognitive Driving Rehabilitation in Virtual Environments (NeuroDRIVE): A pilot clinical trial for chronic traumatic brain injury.

BACKGROUND: Virtual reality (VR) technology may provide an effective means to integrate cognitive and functional approaches to TBI rehabilitation. However, little is known about the effectiveness of VR rehabilitation for TBI-related cognitive deficits. In response to these clinical and research gaps, we developed Neurocognitive Driving Rehabilitation in Virtual Environments (NeuroDRIVE), an intervention designed to improve cognitive performance, driving safety, and neurobehavioral symptoms. OBJECTIVE: This pilot clinical trial was conducted to examine feasibility and preliminary efficacy of NeuroDRIVE for rehabilitation of chronic TBI. METHODS: Eleven participants who received the intervention were compared to six wait-listed participants on driving abilities, cognitive performance, and neurobehavioral symptoms. RESULTS: The NeuroDRIVE intervention was associated with significant improvements in working memory and visual search/selective attention- two cognitive skills that represented a primary focus of the intervention. By comparison, no significant changes were observed in untrained cognitive areas, neurobehavioral symptoms, or driving skills. CONCLUSIONS: Results suggest that immersive virtual environments can provide a valuable and engaging means to achieve some cognitive rehabilitation goals, particularly when these goals are closely matched to the VR training exercises. However, additional research is needed to augment our understanding of rehabilitation for driving skills, cognitive performance, and neurobehavioral symptoms in chronic TBI.

Evolving roles of scientists as change agents in science education over a decade: SFES roles beyond discipline-based education research.

To what extent have positions for science education specialists as change agents within science departments persisted and evolved over the past decade? We addressed this question by studying a population of Science Faculty with Education Specialties (SFES) first described in 2008. SFES are university science faculty who engage in undergraduate science education, K-12 science education, and/or research in science education. Compared to a decade ago, SFES are now more prevalent and more likely to be formally trained in science education. Many identify as discipline-based education researchers (DBER) but assert that their SFES and DBER roles are nonequivalent. SFES have garnered university administrator support through varied science education activities, and these insights into the evolving role of scientists in science education have implications for many stakeholders.

IMP1 3' UTR shortening enhances metastatic burden in colorectal cancer.

The RNA-binding protein insulin-like growth factor 2 mRNA binding protein 1 (IMP1) is overexpressed in colorectal cancer (CRC); however, evidence for a direct role for IMP1 in CRC metastasis is lacking. IMP1 is regulated by let-7 microRNA, which binds in the 3' untranslated region (UTR) of the transcript. The availability of binding sites is in part controlled by alternative polyadenylation, which determines 3' UTR length. Expression of the short 3' UTR transcript (lacking all microRNA sites) results in higher protein levels and is correlated with increased proliferation. We used in vitro and in vivo model systems to test the hypothesis that the short 3' UTR isoform of IMP1 promotes CRC metastasis. Herein we demonstrate that 3' UTR shortening increases IMP1 protein expression and that this in turn enhances the metastatic burden to the liver, whereas expression of the long isoform (full length 3' UTR) does not. Increased tumor burden results from elevated tumor surface area driven by cell proliferation and cell survival mechanisms. These processes are independent of classical apoptosis pathways. Moreover, we demonstrate the shifts toward the short isoform are associated with metastasis in patient populations where IMP1-long expression predominates. Overall, our work demonstrates that different IMP1 expression levels result in different functional outcomes in CRC metastasis and that targeting IMP1 may reduce tumor progression in some patients.

The Molecular Basis of Metastatic Colorectal Cancer.

PURPOSE OF REVIEW: Metastatic colorectal cancer (CRC) is a vexing clinical problem. In contrast to early stage disease, once CRC metastasizes to other organs, long-term survival is compromised. We seek to review the molecular pathogenesis, animal models, and functional genomics for an enhanced understanding of how CRC metastasizes and how this can be exploited therapeutically. RECENT FINDINGS: Mouse models may recapitulate certain aspects of metastatic human CRC and allow for studies to identify regulators of metastasis. Modulation of transcription factors, onco-proteins, or tumor suppressors have been identified to activate known metastatic pathways. CD44 variants, microRNAs and RNA binding proteins are emerging as metastatic modulators. SUMMARY: CRC metastasis is a multi-faceted and heterogeneous disease. Despite common pathways contributing to metastatic development, there are numerous variables that modulate metastatic signals in subsets of patients. It is paramount that studies continue to investigate metastatic drivers, enhancers and inhibitors in CRC to develop therapeutic targets and improve disease outcomes.

Critical questions: Advancing the health of female Veterans.

PURPOSE: Women are the fastest growing Veteran population in the United States and many receive all or part of their health care outside of the Department of Veterans Affairs (VA). The purpose of this article is to review the healthcare issues of women Veterans and discuss implications for care. DATA SOURCES: Review of selected literature, VA resources and guidelines, and expert opinion. CONCLUSIONS: Few providers are aware of the impact military service has on the health of women and fail to ask the all-important question, "Have you served in the military?" Recognizing women's military service can reveal important information that can answer perplexing clinical questions, aid in designing comprehensive plans of care, and enable women to receive the assistance needed to address complex physical and psychosocial issues to improve the quality of their lives. IMPLICATIONS FOR PRACTICE: There are gender disparities related to physical health conditions, mental health issues, environmental exposures, and socioeconomic factors that contribute to female Veterans' vulnerabilities. Many of the health conditions, if recognized in a timely manner, can be ameliorated and shift the health trajectory of this population. Clinicians play a critical role in identifying health risk and helping female Veterans start the sometimes arduous journey toward wellness. Discovering and acknowledging women's military history is critical in ensuring quality care and appropriate decision making.

Evaluating the clinical utility of the Validity-10 for detecting amplified symptom reporting for patients with mild traumatic brain injury and comorbid psychological health conditions.

The objective of this study was to compare the Validity-10 scale with the PAI Negative Impression Management Scale (PAI-NIM) for detecting exaggerated symptom reporting in active-duty military service members (SMs) admitted with unremitting mild TBI symptoms and comorbid psychological health conditions (mTBI/PH). Data were analyzed from 254 SMs who completed the Neurobehavioral Symptom Inventory (NSI) and Personality Assessment Inventory (PAI) as a part of a larger battery of self-report symptom scales upon admission to the intensive-outpatient TBI treatment program at a military medical center. Symptom exaggeration was operationalized using the PAI Negative Impression Management Scale (PAI-NIM). A PAI-NIM score of ≥73 was categorized as positive for symptom exaggeration (SVTpos), while a lower score was categorized as negative for symptom exaggeration (SVTneg). SMs in the SVTpos group (n = 34) had significantly higher scores (p ≤ .004) on the PAI clinical scales as well as on the NSI total score (range: d = 0.59-1.91) compared to those who were SVTneg (n = 220). The optimal cut-score for the NSI Val-10 scale to identify possible symptom exaggeration was ≥26 (sensitivity = .29, specificity = .95, PPP = .74, NPP = .71). In patients suffering from mTBI/PH, the Validity-10 requires a higher cut-score than previously reported to be useful as a metric of exaggerated symptom reporting.

DNA/MVA Vaccination of HIV-1 Infected Participants with Viral Suppression on Antiretroviral Therapy, followed by Treatment Interruption: Elicitation of Immune Responses without Control of Re-Emergent Virus.

GV-TH-01, a Phase 1 open-label trial of a DNA prime­Modified Vaccinia Ankara (MVA) boost vaccine (GOVX-B11), was undertaken in HIV infected participants on antiretroviral treatment (ART) to evaluate safety and vaccine-elicited T cell responses, and explore the ability of elicited CD8+ T cells to control viral rebound during analytical treatment interruption (TI). Nine men who began antiretroviral therapy (ART) within 18 months of seroconversion and had sustained plasma HIV-1 RNA <50 copies/mL for at least 6 months were enrolled. Median age was 38 years, median pre-ART HIV-1 RNA was 140,000 copies/ml and mean baseline CD4 count was 755/µl. Two DNA, followed by 2 MVA, inoculations were given 8 weeks apart. Eight subjects completed all vaccinations and TI. Clinical and laboratory adverse events were generally mild, with no serious or grade 4 events. Only reactogenicity events were considered related to study drug. No treatment emergent viral resistance was seen. The vaccinations did not reduce viral reservoirs and virus re-emerged in all participants during TI, with a median time to re-emergence of 4 weeks. Eight of 9 participants had CD8+ T cells that could be stimulated by vaccine-matched Gag peptides prior to vaccination. Vaccinations boosted these responses as well as eliciting previously undetected CD8+ responses. Elicited T cells did not display signs of exhaustion. During TI, temporal patterns of viral re-emergence and Gag-specific CD8+ T cell expansion suggested that vaccine-specific CD8+ T cells had been stimulated by re-emergent virus in only 2 of 8 participants. In these 2, transient decreases in viremia were associated with Gag selection in known CD8+ T cell epitopes. We hypothesize that escape mutations, already archived in the viral reservoir, plus a poor ability of CD8+ T cells to traffic to and control virus at sites of re-emergence, limited the therapeutic efficacy of the DNA/MVA vaccine. TRIAL REGISTRATION: clinicaltrials.gov NCT01378156.

Brain-derived neurotropic factor polymorphisms, traumatic stress, mild traumatic brain injury, and combat exposure contribute to postdeployment traumatic stress.

BACKGROUND: In addition to experiencing traumatic events while deployed in a combat environment, there are other factors that contribute to the development of posttraumatic stress disorder (PTSD) in military service members. This study explored the contribution of genetics, childhood environment, prior trauma, psychological, cognitive, and deployment factors to the development of traumatic stress following deployment. METHODS: Both pre- and postdeployment data on 231 of 458 soldiers were analyzed. Postdeployment assessments occurred within 30 days from returning stateside and included a battery of psychological health, medical history, and demographic questionnaires; neurocognitive tests; and blood serum for the D2 dopamine receptor (DRD2), apolipoprotein E (APOE), and brain-derived neurotropic factor (BDNF) genes. RESULTS: Soldiers who screened positive for traumatic stress at postdeployment had significantly higher scores in depression (d = 1.91), anxiety (d = 1.61), poor sleep quality (d = 0.92), postconcussion symptoms (d = 2.21), alcohol use (d = 0.63), traumatic life events (d = 0.42), and combat exposure (d = 0.91). BDNF Val66 Met genotype was significantly associated with risk for sustaining a mild traumatic brain injury (mTBI) and screening positive for traumatic stress. Predeployment traumatic stress, greater combat exposure and sustaining an mTBI while deployed, and the BDNF Met/Met genotype accounted for 22% of the variance of postdeployment PTSD scores (R (2)  = 0.22, P < 0.001). However, predeployment traumatic stress, alone, accounted for 17% of the postdeployment PTSD scores. CONCLUSION: These findings suggest predeployment traumatic stress, genetic, and environmental factors have unique contributions to the development of combat-related traumatic stress in military service members.

Fostering Change from Within: Influencing Teaching Practices of Departmental Colleagues by Science Faculty with Education Specialties.

Globally, calls for the improvement of science education are frequent and fervent. In parallel, the phenomenon of having Science Faculty with Education Specialties (SFES) within science departments appears to have grown in recent decades. In the context of an interview study of a randomized, stratified sample of SFES from across the United States, we discovered that most SFES interviewed (82%) perceived having professional impacts in the realm of improving undergraduate science education, more so than in research in science education or K-12 science education. While SFES reported a rich variety of efforts towards improving undergraduate science education, the most prevalent reported impact by far was influencing the teaching practices of their departmental colleagues. Since college and university science faculty continue to be hired with little to no training in effective science teaching, the seeding of science departments with science education specialists holds promise for fostering change in science education from within biology, chemistry, geoscience, and physics departments.
