A comparative framework for understanding and addressing interpersonal gun violence.

Gun violence, often characterized as a singular issue, is not one cohesive problem. Instead, it takes many forms resulting from the complex interplay of multiple factors. Outcomes of gun violence also vary significantly. They may be (a) physically non-injurious (a gun is brandished), (b) injurious but non-lethal, or (c) lethal. To understand and address gun violence effectively, it is essential to consider various risk factors for both non-lethal and lethal gun violence victimization, using a comprehensive, comparative framework. We present a novel comparative framework for better understanding gun violence, and for developing policy responses to this violence. We disaggregate gun violence into its various forms and propose a conceptualization of risk factors in discrete categories, each with important implications for policy intervention. While we emphasize the value of this framework for understanding and combatting interpersonal gun violence in America, the research and policy approaches discussed here should be equally applicable to other international contexts with gun violence as a serious public health issue as well.

The relevance of a right scale for sampling when studying high-resolution behavioral dynamics.

Many species used in behavioral studies are small vertebrates with high metabolic rates and potentially enhanced temporal resolution of perception. Nevertheless, the selection of an appropriate scales to evaluate behavioral dynamics has received little attention. Herein, we studied the temporal organization of behaviors at fine-grain (i.e. sampling interval ≤1s) to gain insight into dynamics and to rethink how behavioral events are defined. We statistically explored high-resolution Japanese quail (Coturnix japonica) datasets encompassing 17 defined behaviors. We show that for the majority of these behaviors, events last predominately <300ms and can be shorter than 70ms. Insufficient sampling resolution, even in the order of 1s, of behaviors that involve spatial displacement (e.g. walking) yields distorted probability distributions of event durations and overestimation of event durations. Contrarily, behaviors without spatial displacement (e.g. vigilance) maintain non-Gaussian, power-law-type distributions indicative of long-term memory, independently of the sampling resolution evaluated. Since data probability distributions reflect underlying biological processes, our results highlight the importance of quantification of behavioral dynamics based on the temporal scale pertinent to the species, and data distribution. We propose a hierarchical model that links diverse types of behavioral definitions and distributions, and paves the way towards a statistical framework for defining behaviors.

What If They Were White? The Differential Arrest Consequences of Victim Characteristics for Black and White Co-offenders.

A substantial body of research focuses on racial disparity in the criminal justice system, with mixed results due to difficulty in disentangling differential offending from racial bias. Additionally, some research has demonstrated that victim characteristics can exacerbate racial disparity in outcomes for offenders, but little research has focused on the arrest stage. We use a quasi-experimental approach that examines incidents involving co-offending pairs to isolate the influence of offender race on arrest, beyond any characteristics of the incident itself, and we test for moderating effects of victim race and sex on racial disparities in arrest. Our findings reveal that, on average, when two offenders of different races commit the same offense together against the same victim, Black offenders are significantly more likely to be arrested than their White co-offending partners, especially for assault offenses. More importantly, this effect-for both assaults and homicides-is particularly strong when the victim is a White woman. Because these differences are between two offenders who commit the same offense together, we argue that the most plausible explanation for the differences is the presence of racial bias or discrimination.

Anti-Asian Xenophobia, Hate Crime Victimization, and Fear of Victimization During the COVID-19 Pandemic.

While the World Health Organization advised against referring to COVID-19 using racial overtones, as the COVID-19 pandemic spread, many disparagingly called it the "Wuhan virus," the "Chinese virus," and other terms. In this context, the FBI warned police agencies about an expected increase in anti-Asian hate crimes during the early months of the pandemic. But, while some researchers and media outlets discussed these potential increases at length, very few studies have been able to directly assess the nature of anti-Asian hate and bias victimization during the pandemic. Following this, the current study directly examines variation in anti-Asian bias and victimization in the United States during the COVID-19 pandemic. Specifically, this research presents results from two studies using a survey of 3,163 non-Asian and 575 Asian American and Pacific Islander respondents, respectively. The first study examines the prevalence of anti-Asian xenophobia among the non-Asian sample and assesses differences in these prejudicial attitudes across respondent characteristics, while the second study examines variation in experiences with bias during the pandemic among the Asian sample. The results illustrate the ubiquity of anti-Asian sentiment, suggesting that those who indicate greater fear of the pandemic report more prejudicial attitudes, as well as important racial differences in these patterns. The results also demonstrate the extent to which the pandemic has impacted individual experiences with anti-Asian bias victimization, such that more than one-third of Asian respondents report bias victimization during the pandemic, and more than half of Asian respondents report that they know someone who has been victimized. These patterns have important implications for addressing COVID-19-related hate crime moving forward.

The insemination status and social context influences quail laying and social behavior: A novel experimental set up.

Japanese quails in wild life live in small groups with females being even solitary during the laying period. Although it is a poultry species widely used for egg production, information regarding laying behavior motivations or influencing variables is scarce. Our study focuses on evaluating along 7 d the quail laying behavior in a novel environmental set up. This set up allows the female to choose between remaining separated from a conspecific in one side of the apparatus or to voluntarily enter their space (box-mate side) and interact with it. We evaluated whether the female insemination status prior to enter the environmental set up, and the presence of a female or a male partner in the box-mate side can influence their laying and social behavior. Thus, 4 experimental groups were established. Females spent a higher (P < 0.05) percentage of time in the box-mate side than in their separated sector in all groups. In 3 of the 4 experimental groups (non-inseminated females interacting with a female or a male box-mate, and inseminated females interacting with a male box-mate) females also laid a greater percentage (≥65%, P < 0.05, in all cases) of eggs in the box-mate sector than in their separated sector. However, the group of inseminated females that interacted with a female box-mate shifted their egg distribution and laid equally between both sides of the apparatus. Aggressive social interactions were reduced (P < 0.05) throughout the testing days but this was depending upon the female insemination status and the sex of their box-mate. Findings suggest that females can change their laying side choice when they are inseminated but depending on the sex identity of their box-mate partners. Thus, providing quail female breeders with the option of laying their eggs in separated enclosures from conspecifics could be key to favor their well-being.

Severity matters: The moderating effect of offense severity in predicting racial differences in reporting of bias and nonbias victimization to the police.

OBJECTIVE: Previous research has noted contradictory findings regarding race and police notification, such that Black people indicate higher levels of distrust in the police yet report victimization to the police at rates similar to or higher than others. We investigated the role of offense severity in accounting for these discrepancies. HYPOTHESES: We hypothesized that severity would moderate racial differences in reporting, such that Black victims would be less likely to report less severe victimization but more likely to report more severe victimization. We expected that these differences would be less pronounced for bias-motivated crime, regardless of other markers of severity. METHOD: We used data from the 2003-2016 National Crime Victimization Survey, including information on 21,510 victimization incidents, 1,105 of which were hate crimes. We conducted logistic regression analyses in which reporting was regressed on victim race, offense severity, hate crime status, and control variables. We also examined interactive effects to disentangle whether severity moderated racial differences in notification. RESULTS: We observed a three-way interaction of Black victims, offense severity, and hate crime status. Specifically, for nonbias incidents, Black victims were more likely than White victims to report severe incidents, but there was no racial difference in reporting nonsevere incidents. Additionally, for nonsevere incidents, Black victims were more likely than White victims to report hate crimes, but there was no racial difference in reporting nonhate crimes. CONCLUSIONS: Offense severity plays an important role in the victim decision-making process. These patterns are different, however, by race and for hate crime victims, suggesting that people perceive hate crimes as important to report, regardless of their severity.

Hate Crime and Place: The Spatial and Temporal Concentration of Bias-Motivated Crime in Washington, D.C.

Prior research suggests that many crime types are spatially concentrated and stable over time. Hate crime, however, is a unique crime type that is etiologically distinct from others. As such, examination of hate crime from a spatial and temporal perspective offers an opportunity to understand hate crime and the spatial concentration of crime more generally. The current study examines the spatial stability of hate crimes reported to the police in Washington, D.C., from 2012 through 2018 using street segments, intersections, and block groups as units of analysis. Findings reveal that hate crime is spatially concentrated, with less than 4% of street segments and intersections experiencing hate crime over the study period. Results reveal a high degree of spatial stability, both year-to-year and over the long term even when restricting the analysis to units that experienced at least one hate crime.

[Management of unilateral acquired pulmonary bullous emphysema in a premature infant through selective bronchial intubation. Case report and review of literature]. / Manejo de enfisema intersticial unilateral adquirido en un recién nacido prematuro mediante intubación bronquial selectiva: Descripción de un caso y revisión de la literatura.

INTRODUCTION: Acquired pulmonary bullous emphysema is an infrequent complication of assisted ventilation in the premature infant that is difficult to manage. OBJECTIVE: The goal of this report is to present the case of a premature infant who required selective bronchial intubation as well as to provide a review of the current literature on the subject. CLINICAL CASE: The patient is a 27-week gestational age neonatal female patient whose clinical course was complicated by left unilateral bullous emphysema during assisted ventilation for respiratory distress syndrome. Lower peak inspiratory pressures, higher res piratory frequencies, patient positioning, and lower inspiration time failed to improve the patient's condition. The left lung became critically overinflated and compressed the right lung to the point of atelectasis. The patient was selectively mono intubated through the right main bronchus, which resulted in a collapse of the left emphysematous lung. Single right lung ventilation was continued for 48 hours before restarting conventional ventilation of both lungs. Our patient improved significantly, was extubated 6 days after the procedure and later discharged home with normal chest x-ray images. CONCLUSION: Selective bronchial intubation is a safe and effective procedure in cases of acquired bu llous emphysema when usual ventilatory management fails.

Una mirada histórica a la menstruación a través de una receta médica del siglo xix en el Nuevo Reino de Granada / A historical look at menstruation through a 19th century medical prescription in the New Kingdom of Granada

La menstruación ha tenido diferentes significados en diversas culturas a lo largo de la historia. Desde Regnier de Graaf en el siglo xvii hasta la fecha, pasando por la médica norteamericana Mary Putnam Jacobi a finales del sigloxix, un buen número de pioneros científicos estudiaron el sistema reproductor femenino con el fin de entender la fisiología del ciclo menstrual. En el Nuevo Reino de Granada, durante los siglos xviii yxix, se desarrolló por parte de médicos y boticarios una receta médica a base de agentes herbarios y de origen animal con el fin de regular el ciclo menstrual, disminuyendo de esta forma síntomas asociados a esta condición para evitar el estigma sociocultural que esta condición implicaba para la mujer en aquel entonces. Esta receta se encuentra en la actualidad consignada en el archivo histórico Cipriano Rodríguez Santamaría en la biblioteca Octavio Arizmendi Posada de la Universidad de La Sabana en Chía, Colombia. La redacción y autoría de esta receta no es del todo clara, y su uso se basa eventualmente en la experiencia y observación de quienes en esa época la utilizaron, sin bases científicas para respaldar su eventual efecto modulador y terapéutico.(AU)

Menstruation has had different meanings in various cultures throughout history. From Regnier de Graaf in the 17th century to the American physician Mary Putnam Jacobi in the late 19th century, a number of pioneering scientists have studied the female reproductive system in order to understand the physiology of the menstrual cycle. In the New Kingdom of Granada, during the eighteenth and nineteenth centuries, doctors and apothecaries developed a medical prescription based on herbal and animal products in order to regulate the menstrual cycle. In this way the symptoms associated with this condition were reduced in order to avoid the socio-cultural stigma that it implied for women at that time. This prescription is currently stored in the Cipriano Rodríguez Santamaría Historical Archives at the Octavio Arizmendi Posada Library at La Sabana University in Colombia, South America. The writing and authorship of this prescription is not entirely clear, and its use is based on the experience and observation of those who used it at that time, with no scientific basis to support its eventual modulating and therapeutic effect.(AU)

Extradyadic Sex and Psychological Distress among Married and Cohabiting Young Adults: An Examination of Internalized and Externalized Responses.

Extradyadic sex (EDS) is a major relationship violation, yet it occurs in nearly a quarter of U.S. cohabiting and marital unions. While many relationships dissolve in the wake of EDS, a majority remain intact. Theories of social stress suggest that substantial psychological distress should result unless EDS is a symptom of stress caused by involvement in a relationship marked by other negative characteristics. This study investigates how one's own EDS, a partner's EDS, and mutual EDS are related to internalizing and externalizing behaviors: depressive symptoms and heavy alcohol use, respectively. Analyses of data from the National Longitudinal Study of Adolescent to Adult Health suggest that one's own EDS is associated with heavy alcohol use among cohabiters and spouses and with depressive symptoms among spouses, while partner EDS has no association with either outcome net of confounders. We discuss the implications of these findings in the study's conclusions.

Non-functional alternative splicing caused by a Latino pathogenic variant in a case of PMM2-CDG.

We report on a Mexican mestizo with a multisystemic syndrome including neurological involvement and a type I serum transferrin isoelectric focusing (Tf IEF) pattern. Diagnosis of PMM2-CDG was obtained by clinical exome sequencing (CES) that revealed compound heterozygous variants in PMM2, the encoding gene for the phosphomannomutase 2 (PMM2). This enzyme catalyzes the conversion of mannose-6-P to mannose-1-P required for the synthesis of GDP-Man and Dol-P-Man, donor substrates for glycosylation reactions. The identified variants were c.422G>A (R141H) and c.178G>T, the former being the most frequent PMM2 pathogenic mutation and the latter a previously uncharacterized variant restricted to the Latino population with conflicting interpretations of pathogenicity and that we here report causes leaky non-functional alternative splicing (p.V60Cfs*3).

Japanese quail classified by their permanence in proximity to a high or low density of conspecifics: a search for underpinning variables.

Test of sociality in poultry is mainly based on the bird's individual ability to make quick social discriminations. In recent years, a density-related permanence (DRP) test has been developed that enables us to classify young birds (while in groups) according to their individual permanence in proximity to either a high or low density of conspecifics (HD or LD, respectively). Thus, the result of the classification depends not only on the bird's individual response but also on the outcome of the social interactions within the whole group. The birds' performance in DRP was associated with underlying differences in social responses of their individuals. Quails in homogeneous groups of LD residents responded with less compact groups and higher levels of agonistic interactions to the presence of an intruder and showed higher levels of agonistic interactions among cage-mates than the homogeneous groups of HD birds. An acute stressor also induced a higher corticosterone response in the LD birds than in their HD counterparts. The present study addressed the question of whether contrasting DRP performance by Japanese quail can also reflect underlying differences in fearfulness and social reinstatement responses. Thus, LD and HD categorized juvenile birds underwent one of the following tests: tonic immobility (TI), open-field (OF), or a one-way runway. Results showed that HD birds required more inductions and developed shorter responses (P ≤ 0.05) in the TI test and walked more, faster, and greater distances in the OF (P ≤ 0.05) than their LD counterparts. No differences between groups were found in short social reinstatement responses. The present findings suggest that underlying fearfulness is lower in the HD than in the LD birds. A reduced fearfulness could be regarded as an additional favorable trait of the HD-classified quail to cope with environmental challenging situations.

Immediate and transgenerational effects of thymol supplementation, inactivated Salmonella and chronic heat stress on representative immune variables of Japanese quail.

Environmental challenges are integrated in the inmunoneuroendocrine interplay, impacting the immune system of the challenged individuals, and potentially implying transgenerational effects on their offspring. This study addressed whether dietary supplementation with thymol can modulate the immune response of adult Japanese quail when simultaneously exposed to an inoculum of inactivated Salmonella Enteritidis and a chronic heat stress (CHS). We also evaluated whether the experienced situations by adults can affect the immune response of their undisturbed offspring. In the parental generation, supplemented quail exposed to CHS had a higher inflammatory response and similar values of the heterophil/lymphocyte (H/L) ratio than those that were not supplemented. In their offspring, those chicks whose parents were exposed to CHS showed higher inflammatory response and lower antibody production. Regarding the H/L ratio, chicks whose parents were supplemented showed lower H/L ratio values. Dietary supplementation with thymol partially and positively modulated the inflammatory response and avoided H/L ratio alteration in the parental generation exposed to high environmental temperatures, suggesting these adults were better at dealing with the challenge. The lower H/L ratio values in the offspring suggests that chicks are more capable to deal with potential stressful situations associated with conventional breeding conditions.

Identification through exome sequencing of the first PMM2-CDG individual of Mexican mestizo origin.

Congenital Disorders of Glycosylation (CDG) are scarcely reported from Latin America. We here report on a Mexican mestizo with a multi-systemic syndrome including neurological involvement and a type I transferrin (Tf) isoelectric focusing (IEF) pattern. Clinical exome sequencing (CES) showed known compound missense variants in PMM2 c.422G > A (p.R141H) and c.395 T > C (p.I132T), coding for the phosphomanomutase 2 (PMM2). PMM2 catalyzes the conversion of mannose-6-P to mannose-1-P required for the synthesis of GDP-Man and Dol-P-Man, donor substrates for glycosylation reactions. This is the third reported Mexican CDG patient and the first with PMM2-CDG. PMM2 has been recently identified as one of the top 10 genes carrying pathogenic variants in a Mexican population cohort.

A randomized comparison trial of culturally adapted HIV prevention approaches for Native Americans reducing trauma symptoms versus substance misuse: The Healing Seasons protocol.

Native Americans (NA) experience interrelated risks of trauma exposure, substance use, and HIV risk behaviors that put them at increased risk for HIV infection. Despite these known risk factors, there are very few published randomized trials testing interventions to reduce trauma-related symptoms and substance misuse among NA. METHODS: The Healing Seasons study is a randomized comparsion trial of two counseling strategies, Narrative Exposure Therapy (NET) addressing PTSD or Motivational interviewing with cognitive behavioral therapy skills training (MIST) addressing substance misuse as a means to prevent HIV among NA. Using a community-based participatory research approach, we adapted both evidence-based interventions to be specific to the risk contexts and realities of NA and to include psychoeducational and skill-building components that include cultural-specific stories, virtues, and traditional treatment strategies. Participants, 16 years and older, were recruited from a Pacific Northwest tribal community, screened over the phone, enrolled in person, and randomized in equal numbers to NET or MIST. We stratified by age (16-29 years and 30 or older) and gender (male or female identified) to ensure balance between treatment arms. The primary outcomes were number of sex partners and frequency of sexual acts (with and without condoms), sex under the influence of substances, frequency of substance use, and PTSD severity. DISCUSSION: Behavioral interventions for NA are needed to prevent HIV risk behaviors when faced with trauma symptoms and substance misuse. This study will provide evidence to determine feasibility and efficacy of addressing related risk factors as part of counseling-based HIV prevention intervention to reduce sexual risk among this population. TRIAL REGISTRATION: ClinicalTrials.gov number, NCT03112369, registered April 12, 2017.

EGFR mutation and HPV infection in sinonasal inverted papilloma and squamous cell carcinoma.

BACKGROUND: To evaluate the involvement of EGFR signalling and HPV infection in a cohort of inverted sinonasal papilloma (ISP) and sinonasal squamous cell carcinoma (SNSCC) and their value for prognosis and clinical treatment. METHODS: We analysed 55 ISP, 14 SNSCC associated with ISP (SNSCC-isp) and and 60 SNSCC not associated with ISP (SNSCC-novo) for EGFR gene mutation and copy number gain, protein expression of EGFR and phosporylated EGFR (pEGFR), and HPV-infection and KRAS mutation. Findings were correlated to clinico-pathological and follow-up data. RESULTS: We found EGFR exon 20 mutations in 38% (7/18) ISP, in 50% (6/12) SNSCC-isp and in 5% (1/19) SNSCC-novo. EGFR was expressed in 92% of ISP, while pEGFR was observed in 54% (21/39). SNSCC-isp and SNSCC-novo demonstrated comparable expression of EGFR (57% and 33%) and of pEGFR (44% and 38%). We observed an inverse relation between EGFR exon 20 mutation and pEGFR expression. Four of 39 (10%) ISP carried HPV-16. Oncogenic HPV was detected in 3/12 (25%) SNSSC-isp and in 1/8 (13%) SNSCC-novo. KRAS mutations were not detected in any of the samples. HPV infection was inversely correlated with pEGFR expression but not with EGFR mutation. ISP with EGFR activation by mutation or by phosphorylation had longer ISP-free survival, however, neither EGFR exon 20 mutation, pEGFR expression nor HPV infection demonstrated prognostic value in SNSCC. CONCLUSIONS: EGFR exon 20 mutation is frequent in ISP and SNSCC-isp, while activation of EGFR through phosphorylation also plays an important role. Our data indicate that a large proportion of SNSCC patients could benefit from therapy with modern EGFR inhibitors.
