Understanding Signs and Sources of Anxiety in Urban Elementary Schools Serving Predominately Ethnically/Racially Minoritized Children.

OBJECTIVE: This mixed-methods study examined teachers' perceptions of student anxiety in urban elementary schools serving predominantly low-income and ethnically/racially minoritized youth. METHOD: Most participating teachers were female (87.7%) and from minoritized backgrounds themselves (89.2%), teaching in schools serving predominantly Black/African American (40%) or Hispanic (60%) students, and in which > 70% of students are eligible for free meals. Teachers were asked in surveys (N = 82) and interviews (n = 12) about the nature of student anxiety, and cultural/contextual considerations that influence anxiety. RESULTS: Overall, teachers reported prevalence and signs of student anxiety that were consistent with the literature, but they reported higher levels of impairment than in previous community samples. Regressions revealed that greater levels of student exposure to community violence and higher proportions of Black students were associated with higher teacher-perceived prevalence and concern about student anxiety, respectively. Moreover, greater emotional exhaustion in teachers was associated with higher reports of anxiety-related impairment in students. Thematic coding of interviews emphasized how teachers perceived 1) most student anxieties to be proportional responses to realistic threats and stress in students' lives (e.g. resource insecurity), 2) systems-level problems (e.g. pressure to perform on standardized tests) contribute to student anxiety, and 3) school-based anxiety sources often interact with traumas and stressors students experience outside of school (e.g. immigration experiences). CONCLUSIONS: Relative to the predominant literature that has focused on biological, cognitive, and other intraindividual factors as sources of anxiety, the present work underscores the importance of considering how broader economic and systems-level influences exacerbate anxiety in marginalized youth.

Using video vignettes in research and program evaluation for people with intellectual and developmental disabilities: A case study of the Leadership for Empowerment and Abuse Prevention (LEAP) project.

People with intellectual and developmental disabilities (IDD) are often excluded from meaningful participation in research and program evaluation for various reasons, including protocols and measures that are inaccessible for people with varying cognitive and communication abilities. Emancipatory research models emphasize the importance of inclusive research practices. Video vignettes are a promising tool for research and program evaluation with people with IDD because they are standardized, they use visual imagery rather than relying on written or verbal communication, and they allow for distance from sensitive topics. The Leadership for Empowerment and Abuse Prevention (LEAP) project used video vignettes to evaluate a healthy relationship program for people with IDD. The authors discuss the process of piloting various protocols and measures, which then ultimately led to the use of video vignettes in the evaluation.

miR-190 is upregulated in Epstein-Barr Virus type I latency and modulates cellular mRNAs involved in cell survival and viral reactivation.

Epstein-Barr Virus (EBV) is a prevalent human pathogen infecting over 90% of the population. Much of the success of the virus is attributed to its ability to maintain latency. The detailed mechanisms underlying the establishment and maintenance of EBV latency remain poorly understood. A microRNA profiling study revealed differential expression of many cellular miRNAs between types I and III latency cells, suggesting cellular miRNAs may play roles in regulating EBV latency. mir-190 is the most differentially up-regulated miRNA in type I latency cells as compared with type III latency cells and the up-regulation appears to be attributed to EBER RNAs that express in higher levels in type I latency cells than type III cells. With the aide of a lentiviral overexpression system and microarray analysis, several cellular mRNAs are identified as potential targets of mir-190. By targeting TP53INP1, miR-190 enhances cell survival by preventing apoptosis and relieving G0/G1 cell cycle arrest. Additionally, miR-190 down-regulates NR4A3, a cellular immediate-early gene for EBV reactivation, and inhibits the expression of the viral immediate-early gene bzlf1 and viral lytic DNA replication. Taken together, our data revealed a mechanism that EBV utilizes a cellular microRNA to promote host cell survival and prevent virus from entering lytic life cycle for latency maintenance.

Competing values in serving older and vulnerable adults: adult protective services, mandated reporting, and domestic violence programs.

State mandatory reporting statutes may directly or indirectly list domestic violence programs as among those that are mandated reporters of cases of suspected abuse, neglect, or exploitation of older individuals and those with disabilities. Domestic violence programs, however, may not consider themselves to be mandated reporters, because the responsibility of reporting abuse may be contrary to their programmatic philosophy. In the Commonwealth of Virginia, the potential conflict between domestic violence programs and Adult Protective Services about the issue of mandated reporting has created tension between these organizations as each entity continues interpreting the issues and policies of mandated reporting through its own lens. The authors draw out some of the reasons for the conflict as well as make recommendations for improving relationships between the two organizations, which will ultimately benefit vulnerable adults who are experiencing abuse.

A cluster of exertional rhabdomyolysis affecting a Division I Football team.

OBJECTIVE: To identify risk factors for exertional rhabdomyolysis (ER) among collegiate football athletes. We hypothesized that a back squat workout triggered ER in some players, and that the risk of ER was altered by players' characteristics or other exposures. DESIGN: Case report and case-control study. SETTING: National Collegiate Athletic Association Division I Football Program and an academic medical center. PARTICIPANTS: National Collegiate Athletic Association Division I football players. INDEPENDENT VARIABLES: Characteristics, performance during the implicated workout, and exposures of players. MAIN OUTCOME MEASURES: Exertional rhabdomyolysis was the primary outcome; the hypotheses were formulated before data were collected. RESULTS: Initial serum creatine kinase and creatinine values ranged from 96,987 to 331,044 U/L and from 1.0 to 3.4 mg/dL, respectively. The risk of ER increased as the time and number of sets needed to complete 100 back squats increased [odds ratio (OR), 1.11; 95% confidence interval (CI), 1.03-1.19; P = 0.0051 and OR, 1.33; 95% CI, 1.09-1.63; P = 0.0056, respectively]. Affected players were significantly more likely than unaffected players to report that they went to muscle failure (P = 0.006), did not think they could complete the workout (P = 0.02), and performed extra squats (P = 0.02) during the back squat assignment. For athletes playing skilled or semiskilled positions, the risk of ER increased as the percent body weight lifted increased [OR (corresponding to a 10% increase), 1.77; 95% CI, 1.06-2.94; P = 0.0292]. Drinking protein shakes after the implicated workout was associated with a decreased risk (OR, 0.70; 95% CI, 0.51-0.96; P = 0.0284); the odds decreased about 30% per shake. CONCLUSIONS: Percent body weight lifted, the number of sets, and time needed to complete 100 back squats were significantly associated with increased risk of ER. Affected athletes were more likely to report going to muscle failure, thinking they could complete the workout, and performing extra squats during the back squat assignment. Consuming protein shakes after the implicated workout was associated with a decreased risk. Clinicians, athletes, and athletic program staff must know risk factors for ER and early symptoms of ER.

Depletion of CD4⁺ T cells abrogates post-peak decline of viremia in SIV-infected rhesus macaques.

CD4+ T cells play a central role in the immunopathogenesis of HIV/AIDS, and their depletion during chronic HIV infection is a hallmark of disease progression. However, the relative contribution of CD4+ T cells as mediators of antiviral immune responses and targets for virus replication is still unclear. Here, we have generated data in SIV-infected rhesus macaques (RMs) that suggest that CD4+ T cells are essential in establishing control of virus replication during acute infection. To directly assess the role of CD4+ T cells during primary SIV infection, we in vivo depleted these cells from RMs prior to infecting the primates with a pathogenic strain of SIV. Compared with undepleted animals, CD4+ lymphocyte-depleted RMs showed a similar peak of viremia, but did not manifest any post-peak decline of virus replication despite CD8+ T cell- and B cell-mediated SIV-specific immune responses comparable to those observed in control animals. Interestingly, depleted animals displayed rapid disease progression, which was associated with increased virus replication in non-T cells as well as the emergence of CD4-independent SIV-envelopes. Our results suggest that the antiviral CD4+ T cell response may play an important role in limiting SIV replication, which has implications for the design of HIV vaccines.

Low levels of SIV infection in sooty mangabey central memory CD4⁺ T cells are associated with limited CCR5 expression.

Naturally simian immunodeficiency virus (SIV)-infected sooty mangabeys do not progress to AIDS despite high-level virus replication. We previously showed that the fraction of CD4(+)CCR5(+) T cells is lower in sooty mangabeys compared to humans and macaques. Here we found that, after in vitro stimulation, sooty mangabey CD4(+) T cells fail to upregulate CCR5 and that this phenomenon is more pronounced in CD4(+) central memory T cells (T(CM) cells). CD4(+) T cell activation was similarly uncoupled from CCR5 expression in sooty mangabeys in vivo during acute SIV infection and the homeostatic proliferation that follows antibody-mediated CD4(+) T cell depletion. Sooty mangabey CD4(+) T(CM) cells that express low amounts of CCR5 showed reduced susceptibility to SIV infection both in vivo and in vitro when compared to CD4(+) T(CM) cells of rhesus macaques. These data suggest that low CCR5 expression on sooty mangabey CD4(+) T cells favors the preservation of CD4(+) T cell homeostasis and promotes an AIDS-free status by protecting CD4(+) T(CM) cells from direct virus infection.

Global genomic analysis reveals rapid control of a robust innate response in SIV-infected sooty mangabeys.

Natural SIV infection of sooty mangabeys (SMs) is nonprogressive despite chronic virus replication. Strikingly, it is characterized by low levels of immune activation, while pathogenic SIV infection of rhesus macaques (RMs) is associated with chronic immune activation. To elucidate the mechanisms underlying this intriguing phenotype, we used high-density oligonucleotide microarrays to longitudinally assess host gene expression in SIV-infected SMs and RMs. We found that acute SIV infection of SMs was consistently associated with a robust innate immune response, including widespread upregulation of IFN-stimulated genes (ISGs) in blood and lymph nodes. While SMs exhibited a rapid resolution of ISG expression and immune activation, both responses were observed chronically in RMs. Systems biology analysis indicated that expression of the lymphocyte inhibitory receptor LAG3, a marker of T cell exhaustion, correlated with immune activation in SIV-infected RMs but not SMs. Our findings suggest that active immune regulatory mechanisms, rather than intrinsically attenuated innate immune responses, underlie the low levels of immune activation characteristic of SMs chronically infected with SIV.

Fidelity of plus-strand priming requires the nucleic acid chaperone activity of HIV-1 nucleocapsid protein.

During minus-strand DNA synthesis, RNase H degrades viral RNA sequences, generating potential plus-strand DNA primers. However, selection of the 3' polypurine tract (PPT) as the exclusive primer is required for formation of viral DNA with the correct 5'-end and for subsequent integration. Here we show a new function for the nucleic acid chaperone activity of HIV-1 nucleocapsid protein (NC) in reverse transcription: blocking mispriming by non-PPT RNAs. Three representative 20-nt RNAs from the PPT region were tested for primer extension. Each primer had activity in the absence of NC, but less than the PPT. NC reduced priming by these RNAs to essentially base-line level, whereas PPT priming was unaffected. RNase H cleavage and zinc coordination by NC were required for maximal inhibition of mispriming. Biophysical properties, including thermal stability, helical structure and reverse transcriptase (RT) binding affinity, showed significant differences between PPT and non-PPT duplexes and the trends were generally correlated with the biochemical data. Binding studies in reactions with both NC and RT ruled out a competition binding model to explain NC's observed effects on mispriming efficiency. Taken together, these results demonstrate that NC chaperone activity has a major role in ensuring the fidelity of plus-strand priming.

Targeted Mentoring: Evaluation of a Program.

Targeted mentoring refers to mentoring aimed at a particular population. This article presents the evaluation of a mentoring program for lesbian, gay, bisexual, and transgender (LGBT) persons in social work education. Forty-three mentors and protégés responded to a survey regarding their program experiences. The results highlight the need for targeted mentoring, although some disparities of experience for mentors and protégés in this program are apparent. In general, mentors felt positive about participating, giving back to the LGBT community, and were more satisfied with their experiences than were the protégés, who were looking for more specific types of instrumental and psychosocial support.

Envisaging the adoption process to strengthen gay- and lesbian-headed families: recommendations for adoption professionals.

Although a growing number of child placement agencies are serving lesbians and gay men, a dearth of literature exists for adoption agency policies and practices related to working with this population. This article explores the unique characteristics and strengths of prospective gay and lesbian adoptive parents throughout each of the three phases of the adoption process-preplacement, placement, and postplacement-as well as provides suggestions for adoption professionals working with gays and lesbians. Data from a recent qualitative study of single, gay adoptive fathers are used to illustrate examples and expose areas of potential strengths of adoptive parents not generally explored in the preplacement or preparatory stage. Special attention also is given to the continuing needs of adoptive families headed by gays and lesbians after adoptive placement. Specifically explored are the needs for developing linkages with similar families, as well as providing resources designed to promote successful outcomes of adopted children raised by gays and lesbians.
