Background Despite progress in youth anxiety assessment, there is need for a measure that is simultaneously (a) free, (b) brief, (c) focused broadly on anxiety and avoidance severity, frequency, and interference, and (d) concerned with the past week. The adult overall anxiety severity and impairment scale (OASIS) was adapted to yield a caregiver-report of past week youth anxiety and interference (OASIS-Y). Methods In a sample of diverse youth seeking anxiety services (N=132; 67% racial/ethnic minority) and their caregivers, analyses examined the OASIS-Y factor structure, internal consistency, and convergent and divergent validity. Hierarchical linear modeling in a participant subset examined OASIS-Y sensitivity to treatment-related change. Results OASIS-Y internal consistency was high and confirmatory factor analysis supported a single-factor structure similar to that found in adults. OASIS-Y convergent validity was supported by a medium-sized association with an established, commercially available measure of youth anxiety, and divergent validity was supported by the absence of unique associations with measures of youth attention and externalizing problems. In a sample subset, session-by-session OASIS-Y scores significantly declined across treatment, and declined at a steeper rate among treatment "responders" versus "non-responders," providing evidence of OASIS-Y sensitivity to treatment-related change. Limitations This study focused on a clinical sample and cannot speak to OASIS-Y performance in community settings. Shared method-variance may have also influenced findings. Conclusions This study offers the first psychometric evaluation of the OASIS-Y, and underscores the promising clinical utility of the measure for assessing past week youth anxiety and impairment and for supporting routine outcome monitoring.

Research has examined suicide-related behaviors following exposure to suicide news articles, yet only a handful of studies utilized experimental designs. We aimed to address the limitations of these prior experimental studies by utilizing more realistic suicide articles and more empirically sound measures. 420 participants were randomly assigned to read a series of either suicide-related or neutral news articles, then complete a battery of questionnaires and the Death/Suicide Implicit Association Task. Overall, no significant differences between groups were observed, nor did we observe any moderation effect of individual vulnerabilities (e.g., lifetime suicidal ideation/behavior). We did not observe any immediate effects of exposure to suicide news articles. Further research examining potential mechanisms for imitative effects remains critically needed.

Caveolae, specialized plasma membrane invaginations present in most cell types, play important roles in multiple cellular processes including cell signaling, lipid uptake and metabolism, endocytosis and mechanotransduction. They are found in almost all cell types but most abundant in endothelial cells, adipocytes and fibroblasts. Caveolin-1 (Cav1), the signature structural protein of caveolae was the first protein associated with caveolae, and in association with Cavin1/PTRF is required for caveolae formation. Genetic ablation of either Cav1 or Cavin1/PTRF downregulates expression of the other resulting in loss of caveolae. Studies using Cav1-deficient mouse models have implicated caveolae with human diseases such as cardiomyopathies, lipodystrophies, diabetes and muscular dystrophies. While caveolins and caveolae are extensively studied in extra-ocular settings, their contributions to ocular function and disease pathogenesis are just beginning to be appreciated. Several putative caveolin/caveolae functions are relevant to the eye and Cav1 is highly expressed in retinal vascular and choroidal endothelium, Müller glia, the retinal pigment epithelium (RPE), and the Schlemm's canal endothelium and trabecular meshwork cells. Variants at the CAV1/2 gene locus are associated with risk of primary open angle glaucoma and the high risk HTRA1 variant for age-related macular degeneration is thought to exert its effect through regulation of Cav1 expression. Caveolins also play important roles in modulating retinal neuroinflammation and blood retinal barrier permeability. In this article, we describe the current state of caveolin/caveolae research in the context of ocular function and pathophysiology. Finally, we discuss new evidence showing that retinal Cav1 exists and functions outside caveolae.

Uncontrolled inflammation is associated with neurodegenerative conditions in central nervous system tissues, including the retina and brain. We previously found that the neural retina (NR) plays an important role in retinal immunity. Tumor necrosis factor Receptor-Associated Factor 3 (TRAF3) is a known immune regulator expressed in the retina, however, whether TRAF3 regulates retinal immunity is unknown. We have generated the first conditional NR-Traf3 knockout mouse model (Chx10-Cre/Traf3f/f) to enable studies of neuronal TRAF3 function. Here, we evaluated NR-Traf3 depletion effects on whole retinal TRAF3 protein expression, visual acuity, and retinal structure and function. Additionally, to determine if NR-Traf3 plays a role in retinal immune regulation, we used flow cytometry to assess immune cell infiltration following acute local lipopolysaccharide (LPS) administration. Our results show that TRAF3 protein is highly expressed in the NR and establish that NR-Traf3 depletion does not affect basal retinal structure or function. Importantly, NR-Traf3 promoted LPS-stimulated retinal immune infiltration. Thus, our findings propose NR-Traf3 as a positive regulator of retinal immunity. Further, the NR-Traf3 mouse provides a tool for investigations of neuronal TRAF3 as a novel potential target for therapeutic interventions aimed at suppressing retinal inflammatory disease and may also inform treatment approaches for inflammatory neurodegenerative brain conditions.

Objective Very few controlled trials have evaluated targeted treatment methods for childhood selective mutism (SM); the availability of evidence-based services remains limited. This study is the first controlled trial to evaluate an intensive group behavioral treatment (IGBT) for children with SM. Method Twenty-nine children with SM (5-9 years; 76% female; 35% ethnic minority) were randomized to immediate SM 5-day IGBT or to a 4-week waitlist with psychoeducational resources (WLP), and were assessed at Week 4 and again 8 weeks into the following school year. Results IGBT was associated with high satisfaction and low perceived barriers to treatment participation. At Week 4, 50% of the immediate IGBT condition and 0% of the WLP condition were classified as "clinical responders." Further, Time × Condition interactions were significant for social anxiety severity, verbal behavior in social situations, and global functioning (but not for SM severity, verbal behavior in home settings, or overall anxiety). School-year follow-up assessments revealed significant improvements across all outcomes. Eight weeks into the following school year, 46% of IGBT-treated children were free of an SM diagnosis. In addition, teachers in the post-IGBT school year rated less school impairment and more classroom verbal behavior relative to teachers in the pre-IGBT school year. Conclusions Findings provide the first empirical support for the efficacy and acceptability of IGBT for SM. Further study is needed to examine mechanisms of IGBT response, and other effective SM treatment methods, in order to clarify which treatment formats work best for which affected children.

Online courses and programs in higher education, including nursing education, continue to multiply exponentially in the United States. In order to meet accreditation standards and build internal standards of quality in online course delivery, nursing administrators and faculty must keep abreast of evidence and best practice in online course design. Awareness and adoption of online standards of excellence may be a departure from standard operating procedure with faculty adept at creating face-to-face courses and mavericks self-taught in online course development. The Plan-Do-Study-Act process for improvement is a viable and scalable method to achieve national certification of online course quality, improving ability to compete in a dynamic online education environment. Considerations of infrastructure and multiple stakeholder groups are critical to successful implementation. The case of one nursing program that used faculty development, team building, and continuous quality improvement to successfully reach national online quality benchmarks is presented.

Across the healthcare spectrum, the provision of evidence-based nutrition education is critical in supporting optimal patient care and health outcomes. Nurses are uniquely positioned to deliver nutrition-focused patient education related to health promotion and disease management; yet widespread evidence of sufficient nutrition instruction in nursing curricula is not available. Although lifestyle and nutrition recommendations have historically been the domain of registered dietitians, interprofessional collaboration requires that nurses are prepared to reinforce and support the dissemination of accurate nutrition education. Interdisciplinary teaching approaches are therefore imperative for consistent communication and execution of nutrition guidance. At a private nursing college, an innovative model for nutrition integration across a nursing curriculum has been developed and implemented. This model features an ongoing instructional partnership between registered dietitian faculty and nurse educators. This integrative model enhances nutrition-related nursing competencies demonstrated by undergraduate nursing students and aims to produce graduates who are confident in the delivery of nutrition-related nursing care.

Background: Video telehealth is an important tool for health care delivery during the COVID-19 pandemic. Given physical distancing recommendations, access to traditional in-person telehealth training for providers has been limited. Telesimulation is an alternative to in-person telehealth training. Telesimulation training with both remote participants and facilitators using telehealth software has not been described. Objective: We investigated the feasibility of a large group telesimulation provider training of telehealth software for remote team leadership skills with common neonatal cases and procedures. Methods: We conducted a 90-min telesimulation session with a combination of InTouch™ provider access software and Zoom™ teleconferencing software. Zoom facilitators activated InTouch software and devices and shared their screen with remote participants. Participants rotated through skill stations and case scenarios through Zoom and directed bedside facilitators to perform simulated tasks using the shared screen and audio connection. Participants engaged in a debrief and a pre- and postsurvey assessing participants' comfort and readiness to use telemedicine. Data were analyzed using descriptive statistics and paired t tests. Results: Twenty (n = 20) participants, five Zoom and eight bedside facilitators participated. Twenty-one (21) pre- and 16 postsurveys were completed. Most participants were attending neonatologists who rarely used telemedicine software. Postsession, participants reported increased comfort with some advanced InTouch features, including taking and sharing pictures with the patient (p < 0.01) and drawing on the shared image (p < 0.05), but less comfort with troubleshooting technical issues, including audio and stethoscope (p < 0.01). Frequently stated concerns were troubleshooting technical issues during a call (75%, n = 16) and personal discomfort with telemedicine applications and technology (56%, n = 16). Conclusion: Large group telesimulation is a feasible way to offer telehealth training for physicians and can increase provider comfort with telehealth software.

Purpose Polymorphisms at the caveolin-1/2 locus are associated with glaucoma and IOP risk and deletion of caveolin-1 (Cav1) in mice elevates IOP and reduces outflow facility. However, the specific location/cell type responsible for Cav1-dependent regulation of IOP is unclear. We hypothesized that endothelial Cav1 in the conventional outflow (CO) pathway regulate IOP via endothelial nitric oxide synthase (eNOS) signaling. Methods We created a mouse with targeted deletion of Cav1 in endothelial cells (Cav1ΔEC) and evaluated IOP, outflow facility, outflow pathway distal vascular morphology, eNOS phosphorylation, and tyrosine nitration of iridocorneal angle tissues by Western blotting. Results Endothelial deletion of Cav1 resulted in significantly elevated IOP versus wild-type mice but not a concomitant decrease in outflow facility. Endothelial Cav1 deficiency did not alter the trabecular meshwork or Schlemm's canal morphology, suggesting that the effects observed were not due to developmental deformities. Endothelial Cav1 deletion resulted in eNOS hyperactivity, modestly increased protein nitration, and significant enlargement of the drainage vessels distal to Schlemm's canal. L-Nitro-arginine methyl ester treatment reduced outflow in Cav1ΔEC but not wild-type mice and had no effect on the size of drainage vessels. Endothelin-1 treatment decrease the outflow and drainage vessel size in both wild-type and Cav1ΔEC mice. Conclusions Our results suggest that hyperactive eNOS signaling in the CO pathway of both Cav1ΔEC and global Cav1 knockout mice results in chronic dilation of distal CO vessels and protein nitration, but that Cav1 expression in the trabecular meshwork is sufficient to rescue CO defects reported in global Cav1 knockout mice.

Despite recent advances in the treatment of early child social anxiety, the broad accessibility of brick-and-mortar services has been limited by traditional barriers to care, and more recently by new obstacles related to efforts to slow the spread of COVID-19. The present waitlist-controlled trial examined the preliminary efficacy of a family-based behavioral parenting intervention (i.e., the iCALM Telehealth Program) that draws on Parent-Child Interaction Therapy and videoconferencing to remotely deliver clinician-led care for anxiety in early childhood. Young children (3–8 years) with a diagnosis of social anxiety disorder (N = 40; 65% from ethnic/racial minority backgrounds) were randomly assigned to iCALM or waitlist. Intent-to-treat analyses found that at post, independent evaluators classified roughly half of the iCALM-treated children, but only 6% of waitlist children, as “Responders” (Wald test = 4.51; p = .03). By Post, iCALM led to significantly greater reductions than waitlist in child anxiety symptoms, fear, discomfort, and anxiety-related social impairment, and also led to greater improvements in child soothability. By 6-month follow-up, the percentage of iCALM-treated children classified as “Responders” rose to roughly 60%. Exploratory moderation tests found iCALM was particularly effective in reducing life impairments and parental distress among families presenting with higher, relative to lower, levels of baseline parental accommodation. The present findings add to a growing body of research supporting the promise of technology-based strategies for broadening the portfolio of options for delivering clinician-led mental health services.

Children with selective mutism (SM) experience significant challenges in a variety of social situations, leading to difficulties with academics, peers, and family functioning. Despite the extensive evidence base for cognitive-behavioral interventions for youth anxiety, the literature has seen relatively limited advancement in specialized treatment methods for SM. In addition, geographic disparities in SM treatment expertise and the roughly 6-month duration of some of the supported SM treatment protocols can further restrict the accessibility and acceptability of quality SM care. Intensive group behavioral treatment (IGBT) for SM was developed to expand the portfolio of evidence-based SM treatment options by offering brief, but high-dose, expert SM intervention in a group format for youth ages 3–10 years that can be completed in 1 week. In this article, we outline IGBT for SM program, which has already received initial support in a waitlist-controlled trial. Our presentation is organized around the five main components of the treatment model: (1) individual “lead-in” sessions, (2) camp (i.e., all-day group sessions for children held in a simulated classroom setting, with an emphasis on graduated exposures and structured reinforcement), (3) parent training, (4) school outreach, and (5) booster treatment, as needed. We conclude with a discussion of clinical considerations and future directions for further IGBT refinement and evaluation.

Recent efforts to improve access to evidence-based parent training programs using online delivery have largely neglected findings that young children with callous-unemotional (CU)-type conduct problems receive less benefit from parent training than children with conduct problems alone. The current study aimed to examine the moderating effect of child CU traits on efficacy and engagement outcomes associated with Internet-delivered Parent-Child Interaction Therapy (iPCIT) versus standard, clinic-based PCIT. Forty families (57.6% non-Hispanic Caucasian) with a 3–5 year-old (M = 3.95 years, SD = 0.9; 83.5% boys) child with a disruptive behavior disorder were randomized to either iPCIT or clinic-based PCIT. Families participated in four assessments across time; child conduct problems, global functioning and treatment responder status, and parent-rated treatment satisfaction were measured. Analyses revealed that the negative influence of CU traits on functional gains was not uniform across treatment formats. Specifically, the detrimental effect of CU traits on functional gains was significantly more pronounced among children treated with iPCIT than clinic-based PCIT. CU traits also predicted lower parental treatment satisfaction across delivery formats, but this effect was more pronounced among iPCIT parents. In contrast, CU traits did not moderate differential effects across iPCIT and clinic-based PCIT for conduct problem severity or treatment response status. Findings suggest that iPCIT is a promising treatment option for early conduct problems, particularly when access-to-care barriers exist, but that further research is needed to determine whether strategic adaptations to online programs can more optimally address the distinct needs of children with clinically significant CU traits.

Chronic ocular inflammation is associated with many retinal degenerative diseases that result in vision loss. The immune-privileged environment and complex organization of retinal tissue allow for the retina’s essential role in visual function processes, yet confound inquiries into cell-specific inflammatory effects that lead to retinal dysfunction and degeneration. Caveolin-1 (Cav1) is an integral membrane protein expressed in many retinal cell populations and has been implicated in retinal immune regulation. However, the direction (i.e., promotion or inhibition) in which Cav1 regulates inflammatory processes in the retina (as well as in other tissues) remains unclear. Previously, we showed that global-Cav1 depletion in the retina paradoxically resulted in reduced retinal inflammatory cytokine production with concurrent elevated retinal immune cell infiltration. We hypothesized that our previous results could be explained by cell-specific Cav1 functions in the retina. Here, we utilized our Chx10 (visual system homeobox 2)-Cre knockout model to deplete Cav1 specifically in the neural retinal (NR) compartment in order to clarify the role of neural retinal-specific Cav1 (NR-Cav1) in the retinal immune response to intravitreal LPS (lipopolysaccharide) challenge. Our data support that neural retinal-derived Cav1 promotes retinal tissue inflammation as Chx10-mediated Cav1 depletion was sufficient to suppress both retinal cytokine production and immune cell infiltration following inflammatory stimulation. Additionally, we identify Traf3 (tumor necrosis factor (TNF) receptor-associated factor 3) as a highly expressed potential immune modulator in retinal tissue that is upregulated with NR-Cav1 depletion. Furthermore, this study highlights the importance for understanding the role of Cav1 (and other proteins) in cell-specific contexts.

This chapter provides an overview of principles, practices, and procedures associated with the exposure-based treatment of childhood selective mutism (SM), a relatively rare but highly impairing anxiety disorder characterized by persistent failure to speak in certain social settings. Recent research has clarified that anxiety and associated avoidance is at the center of SM. In light of growing consensus regarding the critical role of exposure therapy in the treatment of childhood SM, this chapter offers a guiding overview of the key elements of exposure-based treatment for SM—including proper assessment, psychoeducation, reinforcement, stimulus fading, shaping, coping strategies, development of a fear hierarchy, graduated exposures, reinforcement, and homework. We consider important developmental factors throughout, and discuss issues related to promoting generalization of skills in the community, collaborating with schools, calibrating for comorbidity, and improving treatment access. We conclude with a discussion of future directions in the exposure-based treatment of childhood SM.

Posttraumatic stress disorder (PTSD) is a major health concern among veterans, specifically African American veterans, and is commonly comorbid with other negative mental health outcomes including substance use disorders (SUD) and symptoms of depression. The current study examined intolerance of uncertainty as a mediator of the relationship between PTSD and depression symptoms in a sample of African American veterans with a dual diagnosis of PTSD and SUD. Participants included 113 African American veterans who were in treatment for PTSD and SUD at a Veterans Affairs Medical Center. Five mediation analyses were conducted to examine the mediational effect of intolerance of uncertainty on the relationship between PTSD symptom clusters (i.e., total, hyperarousal, numbness, avoidance, and intrusion) and depression symptoms. Findings indicated that intolerance of uncertainty mediated the relationship between four of the five mediation models (i.e., total symptoms, hyperarousal, numbness, and intrusion). These results imply that for African American veterans, higher levels of certain PTSD symptoms were associated with higher levels of intolerance of uncertainty, which in turn were related to increased levels of depression symptoms.

Although the retina resides within the immune-protected ocular environment, inflammatory processes mounted in the eye can lead to retinal damage. Unchecked chronic ocular inflammation leads to retinal damage. Thus, retinal degenerative diseases that result in chronic inflammation accelerate retinal tissue destruction and vision loss. Treatments for chronic retinal inflammation involve corticosteroid administration, which has been associated with glaucoma and cataract formation. Therefore, we must consider novel, alternative treatments. Here, we provide a brief review of our current understanding of chronic innate inflammatory processes in retinal degeneration and the complex role of a putative inflammatory regulator, Caveolin-1 (Cav1). Furthermore, we suggest that the complex role of Cav1 in retinal inflammatory modulation is likely dictated by cell type-specific subcellular localization.

Selective mutism is a relatively uncommon, yet significantly impairing anxiety disorder that causes difficulties in young children when communicating in social situations (such as school) even though they speak normally when they are comfortable (such as at home). Early childhood educators play a unique role in helping to identify selective mutism, given that symptoms often do not occur in the home environment. Parents are incumbent upon educators to bring non-communicative behavior to the parent’s attention, and recognition of selective mutism by early childhood professionals can lead to a referral for appropriate intervention services. Unfortunately, research has indicated a problematic, lengthy lag-time to treatment for children with selective mutism (i.e., symptoms occurring on average 3 years before beginning treatment). Early recognition and treatment of selective mutism can have a profound effect on prognosis; therefore, it is important for educators to understand the difference between shy behavior and symptoms of selective mutism, where to find information regarding selective mutism, and aspects surrounding referral for intervention. This article includes brief descriptions of components of evidence-based treatment for selective mutism including contingency management, stimulus fading techniques, exposure-based practice, and audio/video self-modeling are provided to guide educators of early childhood. Finally, specific classroom strategies for the teacher to use, such as providing a warm classroom environment, using a hierarchy of communication and fixed-choice questions, increasing wait-time for questions, and using video recordings for communication, are reviewed. Use of these strategies will aid in supporting the child’s treatment in the classroom environment, thus reducing the child’s anxiety and increasing verbalizations.

Objective Our primary objective was to determine the potency of externalizing psychopathology as a risk factor for suicidal thoughts and behaviors (STBs). Method We conducted a random effects meta-analysis of 174 prospective studies (839 unique statistical tests) examining externalizing psychopathology and suicidal thoughts and behaviors (STBs) published prior to December 8, 2017. The weighted mean odds ratios for the overall relationship between externalizing psychopathology and STBs were below 2.00 in magnitude, and all risk factor subcategories were also fairly modest predictors of STBs. Taking publication bias into account reduced the magnitude of these associations, particularly for death. Although externalizing psychopathology modestly predicts STBs, this may be due to design limitations of existing studies. Future research should employ shorter follow-up periods, consider risk factors in combination, and focus on forms of externalizing psychopathology that have not been studied extensively. Results The weighted mean odds ratios for the overall relationship between externalizing psychopathology and STBs were below 2.00 in magnitude, and all risk factor subcategories were also fairly modest predictors of STBs. Taking publication bias into account reduced the magnitude of these associations, particularly for death. Additionally, our results were mostly consistent regardless of sample age, sample severity, follow-up length, and predictor scale. Conclusions Although externalizing psychopathology modestly predicts STBs, this may be due to design limitations of existing studies. Future research should employ shorter follow-up periods, consider risk factors in combination, and focus on forms of externalizing psychopathology that have not been studied extensively.

Social support is a known protective factor against the negative psychological impact of natural disasters. Most past research has examined how the effects of exposure to traumatic events influences whether someone meets diagnostic criteria for depression and posttraumatic stress disorder (PTSD); it has also suggested sequelae of disaster exposure depends on whether survivors are displaced from their homes. To capture the full range of the psychological impact of natural disasters, we examined the buffering effects of social support on depressive symptoms and cluster-specific PTSD symptoms, with consideration of displacement status. In a survey conducted 18 to 24 months after Hurricane Katrina, 810 adults exposed to the disaster reported the number of Katrina-related traumatic events experienced, perceived social support 2 months post-Katrina, and cluster-specific PTSD and depressive symptoms experienced since Katrina. Analyses assessed the moderating effects of social support and displacement and the conditional effects of displacement status. Social support significantly buffered the negative effect of Katrina-related traumatic events on depressive symptoms, B = -0.10, p = .001, and avoidance and arousal PTSD symptoms, B = -0.02, p = .035 and B = -0.02, p = .042, respectively. Three-way interactions were nonsignificant. Conditional effects indicated social support buffered development of depressive symptoms across all residents; however, the moderating effects of support on avoidance and arousal symptoms only appeared significant for nondisplaced residents. Results highlight the protective effects of disaster-related social support among nondisplaced individuals, and suggest displaced individuals may require more formal supports for PTSD symptom reduction following a natural disaster.

Although peer support in response to online disclosures of suicidality may be imperative for suicide prevention efforts, little is known as to how often support is provided or what predicts giving support. This study addresses this issue by investigating the odds of providing peer support in response to simulated online disclosures of suicidality. While interacting with a simulated Facebook newsfeed, participants (N = 690, Mage = 20.24, 527 female) were given the opportunity to leave comments on two posts disclosing low, moderate, or severe risk for suicide. Participants also completed questionnaires on their symptoms of depression and anxiety, experience with a loved one's suicidality, and Facebook use strategies. Only 33.6% of participants left a positive, supportive comment on at least one of the two suicide posts. Content severity, experience with a loved one's suicide attempts, and use of Facebook to meet people were predictive of providing positive comments. These findings suggest that young adults vary in their propensity to provide support after encountering a suicide disclosure online and that giving support is driven by a combination of contextual and intrapersonal factors.
