Cerebrovascular Complications Associated With Iatrogenic Fungal Meningitis Following Surgical Procedures in Mexico.

Background: The current fungal meningitis outbreak caused by contaminated epidural anesthesia with among patients who underwent surgical procedures in Matamoros, Mexico remains a cause of concern. Its association with an increased susceptibility for cerebrovascular complications (CVC) has not been reported. This single-center study describes 3 patients with a unique pattern of CVC attributed to fungal meningitis.

Evaluating a treatment selection approach for online single-session interventions for adolescent depression.

Background: The question 'what works for whom' is essential to mental health research, as matching individuals to the treatment best suited to their needs has the potential to maximize the effectiveness of existing approaches. Digitally administered single-session interventions (SSIs) are effective means of reducing depressive symptoms in adolescence, with potential for rapid, large-scale implementation. However, little is known about which SSIs work best for different adolescents.

oHSV-P10 reduces glioma stem cell enrichment after oncolytic HSV therapy.

Longstanding evidence implicate glioma stem-like cells as the main drivers contributing toward glioblastoma (GBM) therapy resistance and tumor recurrence. Although oncolytic herpes simplex virus (oHSV) viral therapy is a promising biological therapy recently approved for melanoma (in the United States and Europe) and GBM (in Japan); however, the impact of this therapy on GBM stem-like cells (GSCs) is understudied. Here we show that post-oHSV virotherapy activated AKT signaling results in an enrichment of GSC signatures in glioma, which mimics the enrichment in GSC observed after radiation treatment.

PKR induces TGF-β and limits oncolytic immune therapy.

Background: Mammalian cells have developed multiple intracellular mechanisms to defend against viral infections. These include RNA-activated protein kinase (PKR), cyclic GMP-AMP synthase and stimulation of interferon genes (cGAS-STING) and toll-like receptor-myeloid differentiation primary response 88 (TLR-MyD88). Among these, we identified that PKR presents the most formidable barrier to oncolytic herpes simplex virus (oHSV) replication in vitro.

The chicken wing training model in cerebrovascular microsurgery for the side-to-side bypass.

In the expanding era of endovascular treatment and minimally invasive techniques, the neurosurgical trainees have a steady decrease in the exposure to microsurgical skills. However, there remain a need for neurosurgical trainees to be proficient at such skills, particularly for performing high-stakes interventions such as vascular bypasses. The scarcity of cerebrovascular bypasses coupled with the technical expertise it demands necessitates the presence of a training model for neurosurgical residents and fellows.

RQ Labs: A Cybersecurity Workforce Skills Development Framework.

Unlabelled: This research contributes to the knowledge of how Information Systems (IS) researchers can iteratively intervene with practitioners to co-create instructional programs with a framework designed for fast-paced, rapidly changing IS fields such as cybersecurity. We demonstrate how complex fields, such as cybersecurity, have the need for a skilled workforce that continues to rapidly outpace supply from universities. IS researchers partnering with practitioners can use this research as an exemplar of a method to design, build, and evaluate these innovative co-curricular IS programs.

Web-Based Single Session Intervention for Perceived Control Over Anxiety During COVID-19: Randomized Controlled Trial.

Background: Anxiety is rising across the United States during the COVID-19 pandemic, and social distancing mandates preclude in-person mental health care. Greater perceived control over anxiety has predicted decreased anxiety pathology, including adaptive responses to uncontrollable stressors. Evidence suggests that no-therapist, single-session interventions can strengthen perceived control over emotions like anxiety; similar programs, if designed for the COVID-19 context, could hold substantial public health value.

Replication and Spread of Oncolytic Herpes Simplex Virus in Solid Tumors.

Oncolytic herpes simplex virus (oHSV) is a highly promising treatment for solid tumors. Intense research and development efforts have led to first-in-class approval for an oHSV for melanoma, but barriers to this promising therapy still exist that limit efficacy. The process of infection, replication and transmission of oHSV in solid tumors is key to obtaining a good lytic destruction of infected cancer cells to kill tumor cells and release tumor antigens that can prime anti-tumor efficacy.

A randomized trial of online single-session interventions for adolescent depression during COVID-19.

The COVID-19 pandemic has potentially increased the risk for adolescent depression. Even pre-pandemic, <50% of youth with depression accessed care, highlighting needs for accessible interventions. Accordingly, this randomized controlled trial (ClinicalTrials.

Factitious Gastrointestinal Bleeding: A Case Series and Review.

Factitious gastrointestinal bleeding (GIB) is a manifestation of factitious disorder (FD) wherein patients feign GIB in the absence of external gain. As it can be a challenging diagnosis to make, factitious GIB often leads to multiple tests, exposure to contrast agents and radiation, invasive endoscopic and surgical procedures, an increased risk of iatrogenic complications, and increased healthcare costs. Patients who feign GIB often demonstrate characteristic behaviors that may go unnoticed unless they are explicitly addressed.

Predicting Mental Health Treatment Access Among Adolescents With Elevated Depressive Symptoms: Machine Learning Approaches.

A large proportion of adolescents experiencing depression never access treatment. To increase access to effective mental health care, it is critical to understand factors associated with increased versus decreased odds of adolescent treatment access. This study used individual depression symptoms and sociodemographic variables to predict whether and where adolescents with depression accessed mental health treatments.

Embracing Scientific Humility and Complexity: Learning "What Works for Whom" in Youth Psychotherapy Research.

Clinical psychological scientists have spent decades attempting to understand "what works for whom" in the context of youth psychotherapy, toward the longstanding goal of personalizing psychosocial interventions to fit individual needs and characteristics. However, as the articles in this Special Issue jointly underscore, more than 50 years of psychotherapy research has yet to help us realize this goal. In this introduction to the special issue, we outline how and why "aspiration-method mismatches" have hampered progress toward identifying moderators of youth psychotherapy; emphasize the need to embrace etiological complexity and scientific humility in pursuing new methodological solutions and propose individual and structural strategies for better-aligning clinical research methods with the goal of personalizing mental health care for youth with diverse identities and treatment needs.

Symptom centrality and infrequency of endorsement identify adolescent depression symptoms more strongly associated with life satisfaction.

Although depression symptoms are often treated as interchangeable, some symptoms may relate to adolescent life satisfaction more strongly than others. To assess this premise, we first conducted a network analysis on the Mood and Feelings Questionnaire (MFQ) in a large (N = 1,059), cross-sectional sample of community adolescents (age M = 14.72 ± 1.

Getting Fewer "Likes" Than Others on Social Media Elicits Emotional Distress Among Victimized Adolescents.

Three studies examined the effects of receiving fewer signs of positive feedback than others on social media. In Study 1, adolescents (N = 613, M  = 14.3 years) who were randomly assigned to receive few (vs.

Posttreatment Maturation of Medulloblastoma into Gangliocytoma: Report of 2 Cases.

Introduction: We report 2 cases of medulloblastoma maturing into gangliocytoma after receiving multimodal therapy. Here we present 2 cases of diagnosed medulloblastoma which on re-resection were noted to be gangliocytoma without heterogeneity, which is an extremely rare occurrence.

Case Presentation: The first patient, an 11-year-old boy diagnosed with high-risk (non-WNT, non-SHH) medulloblastoma, was treated with near-total surgical resection followed by craniospinal radiation therapy with weekly vincristine.

Acceptability and Utility of an Open-Access, Online Single-Session Intervention Platform for Adolescent Mental Health.

Background: Many youths with mental health needs are unable to access care. Single-session interventions (SSIs) have helped reduce youth psychopathology across multiple trials, promising to broaden access to effective, low-intensity supports. Online, self-guided SSIs may be uniquely scalable, particularly if they are freely available for as-needed use.

Future Directions in Single-Session Youth Mental Health Interventions.

The United States spends more money on mental health services than any other country, yet access to effective psychological services remains strikingly low. The need-to-access gap is especially wide among children and adolescents, with up to 80% of youths with mental health needs going without services, and the remainder often receiving insufficient or untested care. Single-session interventions (SSIs) may offer a promising path toward improving accessibility, cost-effectiveness, and completion rates for youth mental health services.

Network analyses reveal which symptoms improve (or not) following an Internet intervention (Deprexis) for depression.

Background: Depression is a heterogeneous collection of symptoms. Prior meta-analyses using symptom sum scores have shown the Internet intervention, Deprexis, to be an efficacious treatment for depression. However, no prior research has investigated how Deprexis (or any other Internet intervention for depression) impacts specific symptoms of depression.

Contributions of fixed mindsets and hopelessness to anxiety and depressive symptoms: A commonality analysis approach.

Background: Fixed mindsets (beliefs that personal traits are unchangeable) show consistent associations with internalizing symptoms. However, the mindset-internalizing symptom link has previously been studied in isolation of other maladaptive cognitions that relate to internalizing symptoms. Thus, the unique contributions of mindsets to internalizing symptoms remains unclear.

Harnessing Wise Interventions to Advance the Potency and Reach of Youth Mental Health Services.

Despite progress in research on evidence-based treatments (EBTs) for youth psychopathology, many youths with mental health needs do not receive services, and EBTs are not always effective for those who access them. Wise interventions (WIs) may help address needs for more disseminable, potent youth mental health interventions. WIs are single-component, social-psychological interventions designed to foster adaptive meaning-making.

Virtual Reality and Web-Based Growth Mindset Interventions for Adolescent Depression: Protocol for a Three-Arm Randomized Trial.

Background: Depression is the leading cause of disability in youth, with a global economic burden of US >$210 billion annually. However, up to 70% of youth with depression do not receive services. Even among those who do access treatment, 30% to 65% fail to respond and many dropout prematurely, demonstrating a need for more potent, accessible interventions.

Does trauma-focused exposure therapy exacerbate symptoms among patients with comorbid PTSD and substance use disorders?

Background: Although exposure-based therapy is a well-established, effective treatment for post-traumatic stress disorder (PTSD), some practitioners report reluctance to implement it due to concerns that it may exacerbate symptoms of PTSD and commonly comorbid disorders, such as substance use disorders (SUD).

Aim: This study compared the exacerbation of psychological symptoms among participants with comorbid PTSD and SUD who received either SUD treatment alone or SUD treatment integrated with exposure therapy for PTSD.

Method: Participants (N = 71) were treatment-seeking, military Veterans with comorbid PTSD and SUD who were randomized to 12 individual sessions of either (1) an integrated, exposure-based treatment (Concurrent Treatment of PTSD and Substance Use Disorders using Prolonged Exposure; COPE); or (2) a non-exposure-based, SUD-only treatment (Relapse Prevention; RP).
