RESUMO
As policymakers and the U.S. military continue to place an emphasis on the resilience of servicemembers, it is critical to utilize psychometrically sound and valid scales to measure resilience. Using two independent samples of Army soldiers-in-training, this study explored the measurement of resilience in the Army Study to Assess Risk and Resilience among Servicemembers (Army STARRS) New Soldier Study Component (NSS). Exploratory factor analysis (EFA) was used to identify the factor structure of a measure of resilience within the Army STARRS NSS. Confirmatory factor analysis (CFA) was then used to confirm the factor structure, then internal reliability was assessed. Convergent validity of the identified resilience factors was examined using two-tailed bivariate correlations. The EFA identified a three-factor structure of a measure of resilience. The CFA confirm the first-order three-factor structure of stress tolerance, positive orientation, and social resources. Each factor was uniquely distinct from measures of the likelihood of generalized anxiety disorder and major depressive disorder, lifetime stressful events, and social network. Findings highlights the utility of a three-factor aggregate measure of resilience in the Army STARRS NSS and provide practitioners with a more nuanced picture of the role of resilience among soldiers-in-training.

This study examined the relationship between marital warmth (e.g., openly expressing affection, supportive behaviors) and assessments of coping (i.e., challenges coping with military life and self-efficacy in the context of stress) and mental health (i.e., depressive symptoms and anxiety symptoms) in a sample of active duty men and their spouses/romantic partners (N = 234 military couples). Results from a series of multivariate analysis of variance tests indicate that service members and spouses who reported higher levels of marital warmth also reported better coping skills and mental health compared to individuals in couple relationships that demonstrated lower levels of marital warmth. Intervention and prevention implications targeting social support and marital warmth are provided.
RESUMO
BACKGROUND: Previous research indicates an association between adverse childhood experiences (ACES) and health outcomes; however, most of these studies rely on variable-centered techniques. This study implemented a person-centered approach to provide a more nuanced understanding of these relations. METHODS: The sample consisted of 3611 male Marines who completed two surveys, one prior to service and another during or after service. A series of latent class analyses were conducted to identify homogenous subgroups, using ACE categories as indicators. Hierarchical regressions were conducted to examine the relationships between classes, deployment experiences, depression and PTSD, and social support problems. RESULTS: Five classes were identified: Low Adversity (48.8 %), Low Adversity - Parental Separation (PS; 33.1 %), Elevated Adversity (7.0 %), Moderate Adversity - Violence/Safety (5.7 %), and Moderate Adversity - Parental Loss (PL; 5.4 %). Several classes were associated with outcomes; in reference to Low Adversity, Moderate Adversity - PL was associated with depression and PTSD, Elevated Adversity was associated with PTSD and social support problems, and Low Adversity - PS was associated with social support problems. Experiencing moderate to high combat appeared to modify the associations between Moderate Adversity - PL and depression and PTSD. LIMITATIONS: Study sample was limited to U.S. Marines; ACEs indicators were limited to specific categories, not allowing for a full range of potential childhood traumatic experiences. CONCLUSIONS: Findings suggest a nuanced connection between ACEs and mental health; using specific patterns of ACEs, particularly multifaceted indicators of adversity that are inclusive of parental absence may have more utility than the sheer number of ACEs as an indicator for those who may at a heightened risk for mental health concerns.

INTRODUCTION: The Department of Defense aims to maintain mission readiness of its service members. Therefore, it is important to understand factors associated with treatment seeking in order to identify areas of prevention and intervention early in a soldier's career that can promote positive functioning and increase their likelihood of seeking mental health care when necessary. METHOD: Using a theory of planned behavior lens, this study identified potential barriers (risk) and facilitators (resilience) to treatment seeking among 24,717 soldiers-in-training who participated in the New Soldiers Study component of the "Army Study to Assess Risk and Resilience in Servicemembers" (Army STARRS). Approval for this study was granted by the University of Iowa IRB # 201706739. Hierarchal linear regression modeling and independent samples t-tests were used to examine associations between demographics and study variables, intersections of risk and resilience, and to explore differences in the likelihood of seeking help based on mental health diagnoses. RESULTS: A four-stage hierarchical linear regression was conducted, using likelihood of help-seeking as the dependent variable, to identify the most salient factors related to help-seeking. "Step one" of the analysis revealed soldiers-in-training who identified as female, Hispanic or Other ethnicity, and married, divorced, or separated reported a greater likelihood of seeking help. "Step two" of the analysis indicated soldiers-in-training with a history of sexual trauma, experience of impaired parenting, and clinical levels of mental health symptomatology (anxiety, depression, PTSD) reported a greater likelihood of seeking help. Inversely, soldiers-in-training with a history of emotional trauma and parental absence/separation reported a lower likelihood of seeking help. "Step three" of the analysis demonstrated soldiers-in-training with a prior history of seeking help and larger social networks had a greater likelihood of seeking help. "Step four" of the analysis revealed several interactive effects between risk and resilience factors. Specifically, soldiers-in-training who reported greater depressive symptomatology in combination with prior history of treatment seeking reported a greater likelihood of help seeking, whereas soldiers-in-training who reported prior sexual trauma and PTSD in combination with large social networks reported a lower likelihood of seeking help. Finally, a greater percentage of soldiers-in-training with clinical levels of anxiety, depression, and PTSD indicated they would likely seek help in comparison to soldiers-in-training without clinical symptoms. CONCLUSION: Findings suggest few soldiers-in-training are likely to seek help when experiencing a problem. General efforts to encourage help-seeking when needed are warranted with particular focus on subsets of soldiers-in-training (eg, men, those with a history of some adverse childhood experiences). Strengths of this study include the examination of a large sample of soldiers-in-training to identify possible leverage points for early intervention or prevention prior to entering stressful military operating environments. Limitations of this study include the examination of only one military branch and exclusion of soldiers not "in-training." Future studies could consider replicating the current study using a sample of military personnel longitudinally to track behavioral trends as well as looking at military populations outside of basic combat training.

INTRODUCTION: Surgical management of acetabular fractures is often highly complex, and a successful outcome depends upon an appreciation of the fracture pattern and the most appropriate approach to reduce and hold it. Currently, computed tomography (CT) images are used in conjunction with plain x-rays to identify the main fracture components and their spatial relationship to one another, and as such surgeons still have to make decisions based upon their ability to visualise the fracture from the images available. 3D printers have now become widely available and inexpensive, and can be used to rapidly produce life-size models based on CT scans of an individual patient. The availability of patient specific, accurate and detailed models of complex acetabular fractures can aid planning of surgical management on a patient specific basis. CASE REPORT: This report describes the use of a 3D printer to create a life-size model reconstruction of the pelvis of a 48 year old male patient who sustained a left sided associated both column acetabular fracture following a motorbike accident in the Sahara Desert. The model allowed visualisation of the multiple fracture fragments and their relative displacements. The tactile feedback allowed assessment of the different fracture fragments. The relative displacement of the quadrilateral plate and posterior column fragments could be assessed and the surgeon felt that these would be amenable to reduction from an ilioinguinal approach. An anatomic reduction was achieved and was held with the application of a pelvic brim plate with 2 screws lagging the posterior column/quadrilateral plate fragment. CONCLUSION: There are previous examples of 3D models being used in orthopaedic surgery through the use of rapid prototyping, however this method is usually expensive and time consuming. Advances in 3D printer technology offer surgeons a number of advantages when treating these complex fractures. With the ever-increasing economy, ease of use and speed of additive processing, the possible applications of this technology within orthopaedic surgery are numerous. Given the possible applications of this technology, and its ever increasing availability, we feel that its use can only improve patient outcomes and so should be explored further for use in orthopaedic surgery.
RESUMO
Phytophthora isolates associated with Phytophthora major ITS Clade 6 were grouped into 11 phenotypic taxa. These comprised the described morphospecies P. gonapodyides, P. megasperma s. str. and P. humicola; four previously identified but so far undescribed taxa, informally designated here P. sp. O-group, P. sp. Apple-cherry, P. taxon Pgchlamydo, and P. taxon Walnut; and four previously unknown taxa, designated P. taxon Oaksoil, P. taxon Raspberry, P. taxon Forestsoil, and P. taxon Riversoil. With the exception of P. gonapodyides, each phenotypic taxon represented an unique ITS lineage. Two isolates morphologically identical to P. gonapodyides comprised a separate lineage and probably represent another taxon, designated here P. taxon Salixsoil, P. humicola, P. sp. O-group, P. sp. Apple-cherry and P. taxon Walnut grouped together as subclade I. Within subclade II, P. taxon Oaksoil, P. taxon Raspberry, P. taxon Forestsoil, P. taxon Riversoil and P. taxon Pgchlamydo formed a cluster of closely related but phenotypically distinct lineages basal to P. gonapodyides and P. megasperma, P. taxon Salixsoil being the most basal member. The taxonomy, adaptation and breeding systems of Clade 6 taxa are discussed. They show a strong association with forests and riparian ecosystems, only a limited association with agriculture and an ability to tolerate high temperatures. Also, in contrast to most other Phytophthora clades, Clade 6 taxa are predominantly sterile or inbreeding in culture. Only one taxon, P. sp. O-group, appears classically A1/A2 heterothallic.

In several studies of oak decline in Europe, a semi-papillate homothallic Phytophthora taxon was consistently isolated, together with other Phytophthora species, from rhizosphere soil samples. It was also found associated with necrotic fine roots and stem necroses of Fagus sylvatica and Alnus glutinosa. Due to morphological and physiological similarities, the semi-papillate isolates were previously identified as P. syringae by various authors. The morphology, physiology and pathogenicity against fine roots of Quercus robur, Q. petraea and F. sylvatica, bark of A. glutinosa, leaves of Ilex aquifolium and apple fruits of this Phytophthora species are described and compared with those of related and similar Phytophthora species, namely P. ilicis, P. psychrophila, P. quercina, P. citricola and P. syringae. The phylogenetic placement on the basis of ITS and mtDNA sequence data was also examined. Isolates of this taxon produce colonies with stellate to rosaceous growth patterns and limited aerial mycelium on various agar media. Antheridia are predominantly paragynous. In water culture catenulate hyphal swellings and semi-papillate caducous sporangia, that are usually limoniform, ellipsoid or ovoid, are formed abundandly, mostly in lax or dense sympodia. This taxon is a moderately slow growing, low temperature species with optimum and maximum temperatures around 20 and 25 degrees C, respectively. Tested isolates are moderately aggressive to fine roots of oaks and beech, highly aggressive to holly leaves and apple fruits, and slightly pathogenic to alder bark. Thirteen tested isolates had an identical and distinct ITS sequence which was more similar to that of P. ilicis and P. psychrophila than any other known taxa. On the basis of their unique combination of morphological characters, colony growth patterns, cardinal temperatures for growth, growth rates, pathogenicity to oaks, beech, alder, apple and holly, their host range, and ITS and mtDNA sequences the semi-papillate caducous Phytophthora isolates from oaks, beech and alder are clearly separated from related and similar Phytophthora spp., and described as a new species, P. pseudosyringae sp. nov.
