An essential protease, FtsH, influences daptomycin resistance acquisition in Enterococcus faecalis.

Daptomycin is a last-line antibiotic commonly used to treat vancomycin-resistant Enterococci, but resistance evolves rapidly and further restricts already limited treatment options. While genetic determinants associated with clinical daptomycin resistance (DAP) have been described, information on factors affecting the speed of DAP acquisition is limited. The multiple peptide resistance factor (MprF), a phosphatidylglycerol-modifying enzyme involved in cationic antimicrobial resistance, is linked to DAP in pathogens such as methicillin-resistant Staphylococcus aureus.

Volatile methyl jasmonate from roots triggers host-beneficial soil microbiome biofilms.

The rhizosphere is a niche surrounding plant roots, where soluble and volatile molecules mediate signaling between plants and the associated microbiota. The preferred lifestyle of soil microorganisms is in the form of biofilms. However, less is known about whether root volatile organic compounds (rVOCs) can influence soil biofilms beyond the 2-10 mm rhizosphere zone influenced by root exudates.

Developing a Risk Model to Target High-risk Preventive Interventions for Sexual Assault Victimization among Female U.S. Army Soldiers.

Sexual violence victimization is a significant problem among female U.S. military personnel.

Using administrative data to identify U.S. Army soldiers at high-risk of perpetrating minor violent crimes.

Growing concerns exist about violent crimes perpetrated by U.S. military personnel.

Post-traumatic stress disorder associated with life-threatening motor vehicle collisions in the WHO World Mental Health Surveys.

Background: Motor vehicle collisions (MVCs) are a substantial contributor to the global burden of disease and lead to subsequent post-traumatic stress disorder (PTSD). However, the relevant literature originates in only a few countries, and much remains unknown about MVC-related PTSD prevalence and predictors.

Methods: Data come from the World Mental Health Survey Initiative, a coordinated series of community epidemiological surveys of mental disorders throughout the world.

How well can post-traumatic stress disorder be predicted from pre-trauma risk factors? An exploratory study in the WHO World Mental Health Surveys.

Post-traumatic stress disorder (PTSD) should be one of the most preventable mental disorders, since many people exposed to traumatic experiences (TEs) could be targeted in first response settings in the immediate aftermath of exposure for preventive intervention. However, these interventions are costly and the proportion of TE-exposed people who develop PTSD is small. To be cost-effective, risk prediction rules are needed to target high-risk people in the immediate aftermath of a TE.

DSM-5 and ICD-11 definitions of posttraumatic stress disorder: investigating "narrow" and "broad" approaches.

Background: The development of the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) and ICD-11 has led to reconsideration of diagnostic criteria for posttraumatic stress disorder (PTSD). The World Mental Health (WMH) Surveys allow investigation of the implications of the changing criteria compared to DSM-IV and ICD-10.

Methods: WMH Surveys in 13 countries asked respondents to enumerate all their lifetime traumatic events (TEs) and randomly selected one TE per respondent for PTSD assessment.

Subthreshold posttraumatic stress disorder in the world health organization world mental health surveys.

Background: Although only a few people exposed to a traumatic event (TE) develop posttraumatic stress disorder (PTSD), symptoms that do not meet full PTSD criteria are common and often clinically significant. Individuals with these symptoms sometimes have been characterized as having subthreshold PTSD, but no consensus exists on the optimal definition of this term. Data from a large cross-national epidemiologic survey are used in this study to provide a principled basis for such a definition.

Religion and intergroup conflict: findings from the Global Group Relations Project.

How might religion shape intergroup conflict? We tested whether religious infusion-the extent to which religious rituals and discourse permeate the everyday activities of groups and their members-moderated the effects of two factors known to increase intergroup conflict: competition for limited resources and incompatibility of values held by potentially conflicting groups. We used data from the Global Group Relations Project to investigate 194 groups (e.g.

Cumulative traumas and risk thresholds: 12-month PTSD in the World Mental Health (WMH) surveys.

Background: Clinical research suggests that posttraumatic stress disorder (PTSD) patients exposed to multiple traumatic events (TEs) rather than a single TE have increased morbidity and dysfunction. Although epidemiological surveys in the United States and Europe also document high rates of multiple TE exposure, no population-based cross-national data have examined this issue.

Methods: Data were analyzed from 20 population surveys in the World Health Organization World Mental Health Survey Initiative (n = 51,295 aged 18+).

Trauma exposure and posttraumatic stress disorder in a national sample of adolescents.

Objective: Although exposure to potentially traumatic experiences (PTEs) is common among youths in the United States, information on posttraumatic stress disorder (PTSD) risk associated with PTEs is limited. We estimate lifetime prevalence of exposure to PTEs and PTSD, PTE-specific risk of PTSD, and associations of sociodemographics and temporally prior DSM-IV disorders with PTE exposure, PTSD given exposure, and PTSD recovery among U.S.

Mediators of the shame-guilt-psychological adjustment relationship.

A college student sample (109 women, 90 men) was administered measures of psychological adjustment, shame, guilt, personal fear of invalidity, and aspects of empathy, including personal distress in emergencies and fantasy involvement. Consistent with previous studies, shame but not guilt was significantly positively correlated with poor psychological adjustment. Path analyses with bootstrapped mediation tests indicated that the shame-adjustment relationship was significantly mediated by fear of invalidity, personal distress, and fantasy involvement.

Validation of the Narrative Emplotment Scale and its correlations with well-being and psychological adjustment.

Two studies examined correlates of the Narrative Emplotment Scale (NES), which measures the extent to which individuals perceive chance events and unchosen experiences as meaningfully connected. In Study 1 (N=99), the NES demonstrated adequate test-retest stability and good internal reliability. The scale was positively related to paranormal beliefs, mystical experiences, and absorption.

Race as a moderator of the relationship between religiosity and political alignment.

Religiosity, especially religious fundamentalism, is often assumed to have an inherent connection with conservative politics. This article proposes that the relationship varies by race in the United States. In Study 1, race moderated the relationships between religiosity indicators and political alignment in a nationally representative sample.
