Project description:ObjectivesTo differentiate between forms of intimate partner violence (IPV) (victim only, perpetrator only, or participating in reciprocal violence) and examine risk profiles and pregnancy outcomes.DesignProspective.SettingWashington, DC, July 2001 to October 2003.SampleA total of 1044 high-risk African-American pregnant women who participated in a randomised controlled trial to address IPV, depression, smoking and environmental tobacco smoke exposure.MethodsMultivariable linear and logistic regression.Main outcome measuresLow and very low birthweight, preterm and very preterm birth.ResultsFive percent of women were victims only, 12% were perpetrators only, 27% participated in reciprocal violence and 55% reported no IPV. Women reporting reciprocal violence in the past year were more likely to drink, use illicit drugs and experience environmental tobacco smoke exposure and were less likely to be very happy about their pregnancies. Women reporting any type of IPV were more likely to be depressed than those reporting no IPV. Women experiencing reciprocal violence reported the highest levels of depression. Women who were victims of IPV were more likely to give birth prematurely and deliver low-birthweight and very-low-birthweight infants.ConclusionsWe conclude that women were at highest risk for pregnancy risk factors when they participated in reciprocal violence and so might be at higher risk for long-term consequences, but women who were victims of IPV were more likely to show proximal negative outcomes like preterm birth and low birthweight infants. Different types of interventions may be needed for these two forms of IPV.

Project description:While a growing number of studies indicate associations between experiences of bullying and autism spectrum disorder (ASD), it is not clear what roles comorbid behavioral problems may play. We investigated the experiences of children with ASD as victims and/or perpetrators of bullying. Children with ASD epidemiologically ascertained participated in a cross-sectional study. Although children with ASD showed significantly increased risk for bullying involvement compared to community children, after controlling for comorbid psychopathology and other demographic factors, increased risks for being perpetrators or victim-perpetrators disappeared while risk for being bullied/teased continued to be significantly elevated. This finding will help guide medical, educational and community personnel to effectively identify children with ASD at risk for school bullying and develop interventions.

Project description:The present study examined the effect of distant temporal distance on creative thinking and the underlying motivation mechanism. We tested our hypotheses in four studies. In Studies 1-4, participants in the distant temporal distance opposed to the proximal temporal distance performed better on a series of creative thinking tasks: the Verbal Divergent Thinking Test (Study 1), the Chinese Remote Associates Test (Study 2), the Toy Design Task (Study 3) and the Ad Evaluation Task (Study 4). Moreover, Studies 2 and 3 found that promotion motivation mediated the beneficial effect of distant temporal distance on the performance of the two creative thinking tasks. In conclusion, distant temporal distance facilitated creative thinking, and promotion motivation mediated this beneficial effect.

Project description:INTRODUCTION:Workplace sexual violence is not a new phenomenon but has received increased attention recently with the re-emergence of the #metoo movement. Gaps exist in the understanding of the prevalence of this problem in the U.S., its perpetrators, and its impacts. METHODS:Using 2010-2012 data from the National Intimate Partner and Sexual Violence Survey (22,590 women and 18,584 men), this study examined the prevalence of several types of sexual violence by a workplace-related perpetrator (authority figure or nonauthority figure) and numerous impacts of the violence, including psychological impacts, safety concerns, and missing days of work or school. Data were analyzed in 2018. RESULTS:In the U.S., 5.6% of women (almost 7 million) and 2.5% of men (nearly 3 million) reported some type of sexual violence by a workplace-related perpetrator. Almost 4% of women (3.9%) reported sexual violence by nonauthority figures and 2.1% reported authority figures; 2.0% of men reported sexual violence by nonauthority figures, and 0.6% reported authority figures. For women, the most commonly reported sexual violence type was unwanted sexual contact (3.5% of women); for men, it was noncontact unwanted sexual experiences (1.3% of men). An estimated 1 million women (0.8%) have been raped by a workplace-related perpetrator. For women and men, fear was the most commonly reported impact of workplace-related sexual violence. CONCLUSIONS:These findings suggest that workplace prevention efforts that do not address different components of workplace harassment may not be adequate to address all forms of sexual violence occurring across the U.S. in the workplace context.

Project description:Islatravir (MK-8591) is a nucleoside reverse transcriptase translocation inhibitor in development for the treatment and prevention of HIV-1. The potential for islatravir to interact with commonly co-prescribed medications was studied in vitro. Elimination of islatravir is expected to be balanced between adenosine deaminase-mediated metabolism and renal excretion. Islatravir did not inhibit uridine diphosphate glucuronosyltransferase 1A1 or cytochrome p450 (CYP) enzymes CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6, or 3A4, nor did it induce CYP1A2, 2B6, or 3A4. Islatravir did not inhibit hepatic transporters organic anion transporting polypeptide (OATP) 1B1, OATP1B3, organic cation transporter (OCT) 1, bile salt export pump (BSEP), multidrug resistance-associated protein (MRP) 2, MRP3, or MRP4. Islatravir was neither a substrate nor a significant inhibitor of renal transporters organic anion transporter (OAT) 1, OAT3, OCT2, multidrug and toxin extrusion protein (MATE) 1, or MATE2K. Islatravir did not significantly inhibit P-glycoprotein and breast cancer resistance protein (BCRP); however, it was a substrate of BCRP, which is not expected to be of clinical significance. These findings suggest islatravir is unlikely to be the victim or perpetrator of drug-drug interactions with commonly co-prescribed medications, including statins, diuretics, anti-diabetic drugs, proton pump inhibitors, anticoagulants, benzodiazepines, and selective serotonin reuptake inhibitors.

Project description:The social identity approach makes a distinction between behavior motivated by intergroup versus interpersonal identities, which may be relevant to victim blaming in the case of rape. Using a mock jury paradigm, we examined the impact of defining rape as an act of interpersonal violence (personal assault) versus intergroup violence (a "hate crime"), crossed with a manipulation describing the attacker as either an acquaintance or stranger. Defining rape in intergroup terms led to less victim blame than when it was defined in interpersonal terms, and participants blamed the victim more when she was assaulted by an acquaintance than a stranger.

Project description:Powdery mildew is an important disease of cereals, affecting both grain yield and end-use quality. The causal agent of powdery mildew on cereals, Blumeria graminis, has been classified into eight formae speciales (ff.spp.), infecting crops and wild grasses. Advances in research on host specificity and resistance, and on pathogen phylogeny and origins, have brought aspects of the subspecific classification system of B.?graminis into ff.spp. into question, because it is based on adaptation to certain hosts rather than strict host specialization. Cereals therefore cannot be considered as typical non-hosts to non-adapted ff.spp. We introduce the term 'non-adapted resistance' of cereals to inappropriate ff.spp. of B.?graminis, which involves both pathogen-associated molecular pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). There is no clear distinction between the mechanisms of resistance to adapted and non-adapted ff.spp. Molecular evolutionary data suggest that the taxonomic grouping of B.?graminis into different ff.spp. is not consistent with the phylogeny of the fungus. Imprecise estimates of mutation rates and the lack of genetic variation in introduced populations may explain the uncertainty with regard to divergence times, in the Miocene or Holocene epochs, of ff.spp. of B.?graminis which infect cereal crop species. We propose that most evidence favours divergence in the Holocene, during the course of early agriculture. We also propose that the forma specialis concept should be retained for B.?graminis pathogenic on cultivated cereals to include clades of the fungus which are strongly specialized to these hosts, i.e. ff.spp. hordei, secalis and tritici, as well as avenae from cultivated A.?sativa, and that the forma specialis concept should no longer be applied to B.?graminis from most wild grasses.

Project description:The role of empathy and perspective-taking in preventing aggressive behaviors has been highlighted in several theoretical models. In this study, we used immersive virtual reality to induce a full body ownership illusion that allows offenders to be in the body of a victim of domestic abuse. A group of male domestic violence offenders and a control group without a history of violence experienced a virtual scene of abuse in first-person perspective. During the virtual encounter, the participants' real bodies were replaced with a life-sized virtual female body that moved synchronously with their own real movements. Participants' emotion recognition skills were assessed before and after the virtual experience. Our results revealed that offenders have a significantly lower ability to recognize fear in female faces compared to controls, with a bias towards classifying fearful faces as happy. After being embodied in a female victim, offenders improved their ability to recognize fearful female faces and reduced their bias towards recognizing fearful faces as happy. For the first time, we demonstrate that changing the perspective of an aggressive population through immersive virtual reality can modify socio-perceptual processes such as emotion recognition, thought to underlie this specific form of aggressive behaviors.

Project description:?-Lactamases, the major resistance determinant for ?-lactam antibiotics in Gram-negative bacteria, are ancient enzymes whose origins can be traced back millions of years ago. These well-studied enzymes, currently numbering almost 2,800 unique proteins, initially emerged from environmental sources, most likely to protect a producing bacterium from attack by naturally occurring ?-lactams. Their ancestors were presumably penicillin-binding proteins that share sequence homology with ?-lactamases possessing an active-site serine. Metallo-?-lactamases also exist, with one or two catalytically functional zinc ions. Although penicillinases in Gram-positive bacteria were reported shortly after penicillin was introduced clinically, transmissible ?-lactamases that could hydrolyze recently approved cephalosporins, monobactams, and carbapenems later became important in Gram-negative pathogens. Nomenclature is based on one of two major systems. Originally, functional classifications were used, based on substrate and inhibitor profiles. A later scheme classifies ?-lactamases according to amino acid sequences, resulting in class A, B, C, and D enzymes. A more recent nomenclature combines the molecular and biochemical classifications into 17 functional groups that describe most ?-lactamases. Some of the most problematic enzymes in the clinical community include extended-spectrum ?-lactamases (ESBLs) and the serine and metallo-carbapenemases, all of which are at least partially addressed with new ?-lactamase inhibitor combinations. New enzyme variants continue to be described, partly because of the ease of obtaining sequence data from whole-genome sequencing studies. Often, these new enzymes are devoid of any phenotypic descriptions, making it more difficult for clinicians and antibiotic researchers to address new challenges that may be posed by unusual ?-lactamases.

Project description:Objectives Breastfeeding has short- and long-term health benefits for children and mothers, but US breastfeeding rates are suboptimal. Exposure to violence may contribute to these low rates, which vary by race/ethnicity. We studied: (1) whether patterns of violence exposure differ by race/ethnicity and (2) whether these patterns are associated with breastfeeding outcomes. Methods We conducted a secondary analysis of data drawn from self-report surveys completed by a convenience sample of low-income postpartum women (n?=?760) in upstate New York. Latent class analysis was used to identify groups of women with similar responses to seven violence measures, including childhood physical and/or sexual violence, experience of partner violence during or just after pregnancy (physical, emotional, verbal), and neighborhood violence (perceived or by ZIP code). Logistic regression and survival analysis were utilized to determine if classes were associated with breastfeeding initiation, duration, and exclusivity, controlling for demographics. Results Exposure to at least one form of violence was high in this sample (87%). We identified 4 classes defined by violence exposure (combining current and historical exposures). Violence exposure patterns differed between racial/ethnic groups, but patterns were inconsistently associated with breastfeeding plans or outcomes. For White women, history of violence exposure increased the likelihood of earlier breastfeeding cessation. By contrast, among Black women, history of violence exposure increased the likelihood of having a breastfeeding plan and initiating breastfeeding. Conclusions for Practice Some differences between violence exposure classes are likely due to the correlation between race/ethnicity and socioeconomic status in the community studied. Additional studies are warranted to better understand how exposure to violence is related to breastfeeding and how best to support women making decisions about intention, initiation, and duration of breastfeeding.
