Evidence for Environmental Risk Factors and Cumulative Stress Linking Racial/Ethnic Identity and Psychotic-Like Experiences in ABCD Study Data.

Objective: Previous work has found increased endorsement of psychotic-like experiences (PLEs) among marginalized racial and ethnic groups. According to social determinants frameworks, marginalized groups are at increased risk for exposure to socio-environmental risk factors, including systemic factors (eg, poverty and poor housing conditions) and social stressors (eg, discrimination). We examine the extent to which environmental risk factors and stress account for associations between racial/ethnic groups with PLEs.

TRF2 as novel marker of tumor response to taxane-based therapy: from mechanistic insight to clinical implication.

Background: Breast Cancer (BC) can be classified, due to its heterogeneity, into multiple subtypes that differ for prognosis and clinical management. Notably, triple negative breast cancer (TNBC) - the most aggressive BC form - is refractory to endocrine and most of the target therapies. In this view, taxane-based therapy still represents the elective strategy for the treatment of this tumor.

The influence of psychotic-like experiences on intent to seek treatment: Findings from a multi-site community survey of mental health experiences.

Psychotic-like experiences (PLEs) may reflect elevated risk for serious mental illness, including psychosis. Although some studies report an association between PLEs and increased service utilization, there is evidence of unmet need among individuals with PLEs, with few studies exploring the relation between PLEs and intent to seek treatment. Characterizing factors that underlie intent to seek treatment in individuals not otherwise engaged in treatment may assist in determining the role of PLEs and future intentions, and help prioritize symptoms of greatest significance.

The Past, Present, and Future of Psychotherapy Manuals: Protocol for a Scoping Review.

Background: Psychotherapy manuals are critical to the dissemination of psychotherapy treatments. Psychotherapy manuals typically serve several purposes, including, but not limited to, establishing new psychotherapy treatments, training providers, disseminating treatments to those who deliver them, and providing guidelines to deliver treatments with fidelity. Yet, the proliferation of psychotherapy manuals has not been well-understood, and no work has aimed to assess or review the existing landscape of psychotherapy manuals.

Review of factors resulting in systemic biases in the screening, assessment, and treatment of individuals at clinical high-risk for psychosis in the United States.

Background: Since its inception, research in the clinical high-risk (CHR) phase of psychosis has included identifying and exploring the impact of relevant socio-demographic factors. Employing a narrative review approach and highlighting work from the United States, sociocultural and contextual factors potentially affecting the screening, assessment, and service utilization of youth at CHR were reviewed from the current literature.

Results: Existing literature suggests that contextual factors impact the predictive performance of widely used psychosis-risk screening tools and may introduce systemic bias and challenges to differential diagnosis in clinical assessment.

PARP1 allows proper telomere replication through TRF1 poly (ADP-ribosyl)ation and helicase recruitment.

Telomeres are nucleoprotein structures at eukaryotic chromosome termini. Their stability is preserved by a six-protein complex named shelterin. Among these, TRF1 binds telomere duplex and assists DNA replication with mechanisms only partly clarified.

MiR-182-3p targets TRF2 and impairs tumor growth of triple-negative breast cancer.

The telomeric repeat-binding factor 2 (TRF2) is a telomere-capping protein that plays a key role in the maintenance of telomere structure and function. It is highly expressed in different cancer types, and it contributes to cancer progression. To date, anti-cancer strategies to target TRF2 remain a challenge.

The telomeric protein TERF2/TRF2 impairs HMGB1-driven autophagy.

TERF2/TRF2 is a pleiotropic telomeric protein that plays a crucial role in tumor formation and progression through several telomere-dependent and -independent mechanisms. Here, we uncovered a novel function for this protein in regulating the macroautophagic/autophagic process upon different stimuli. By using both biochemical and cell biology approaches, we found that TERF2 binds to the non-histone chromatin-associated protein HMGB1, and this interaction is functional to the nuclear/cytoplasmic protein localization.

Internalized stigma mediates the relation between psychosis-risk symptoms and subjective quality of life in a help-seeking sample.

Subjective quality of life can be compromised in individuals with psychosis-risk symptoms, with poorer quality of life being associated with worse functioning and later transition to psychosis. Individuals who experience psychosis-related symptoms also tend to endorse more internalized (or self-) mental health stigma when compared to controls, potentially contributing to delays in seeking treatment and increased duration of untreated psychosis, as well as interfering with treatment engagement and retention in those already receiving care. Despite these findings, and the growing recognition for prevention in earlier phases of psychotic illness, few studies have examined the relation between psychosis-risk symptoms, internalized stigma, and subjective quality of life in a younger, help-seeking sample.

Mental health care utilization in individuals with high levels of psychosis-like experiences: Associations with race and potentially traumatic events.

Racial inequities in mental health care utilization (MHCU) are well documented. Marginalized racial groups are more likely to report psychosis-like experiences (PLEs) and are at elevated risk for racial discrimination and trauma, impacting PLE severity. Little is known about how factors associated with race impact treatment seeking among individuals reporting PLEs.

Predictors of internalized mental health stigma in a help-seeking sample of youth: The roles of psychosis-spectrum symptoms and family functioning.

Experiencing psychosis-spectrum symptoms is challenging to youth. Among many difficulties, internalized mental health stigma-the internalization of negative stereotypes-can lead to shame and withdrawal. The objective of this study was to better understand the correlates of internalized stigma among a clinical sample of youth with psychosis-spectrum symptoms.

Telepsychotherapy with Youth at Clinical High Risk for Psychosis: Clinical Issues and Best Practices during the COVID-19 Pandemic.

Early detection and prevention of psychosis has become an international priority. Much of this work has focused on youth presenting with attenuated symptoms of psychosis-those at Clinical High Risk for psychosis (CHR)-given their elevated probability of developing the full disorder in subsequent years. Individuals at CHR may be prone to exacerbated psychological distress during the COVID-19 pandemic and its subsequent physical isolation measures, due to heightened stress sensitivity and comorbid mental health problems.

Social work training to reduce duration of untreated psychosis: Methodology and considerations of a web-based training for community providers.

Aim: Outcomes for individuals with psychotic disorders can be improved through early intervention services; however, identification continues to be a major problem in connecting individuals with these services. Social workers form a vast majority of the human service and mental health workforce in the United States and therefore have the potential to play a unique role in identifying and referring those who may benefit from specialty early intervention services.

Methods: The current article describes the methodological design, implementation, and participant recruitment procedures of a large-scale, web-based training program for social workers promoting identification and referral of individuals with emerging symptoms of a mental illness with psychosis in the context of a randomized clinical trial.

Multidimensional Pain Assessment Tools for Ambulatory and Inpatient Nursing Practice.

Background: One of the critical components in pain management is the assessment of pain. Multidimensional measurement tools capture multiple aspects of a patient's pain experience but can be cumbersome to administer in busy clinical settings.

Aim: We conducted a systematic review to identify brief multidimensional pain assessment tools that nurses can use in both ambulatory and acute care settings.

Preliminary support for using the Atypicality Scale from the Behavior Assessment System for Children, Second Edition, to screen for psychosis-spectrum disorders within a college counselling centre.

Aim: Evidence supports the use of brief psychosis-spectrum screeners for identifying individuals at risk for psychosis. Screening has not been well-studied in help-seeking college samples. This study investigated the use of the Behavior Assessment System for Children, Second Edition (BASC-2) Atypicality Scale as a psychosis-spectrum screening tool within a university counselling centre.

SFPQ and NONO suppress RNA:DNA-hybrid-related telomere instability.

In vertebrates, the telomere repeat containing long, non-coding RNA TERRA is prone to form RNA:DNA hybrids at telomeres. This results in the formation of R-loop structures, replication stress and telomere instability, but also contributes to alternative lengthening of telomeres (ALT). Here, we identify the TERRA binding proteins NONO and SFPQ as novel regulators of RNA:DNA hybrid related telomere instability.

TRF2 positively regulates SULF2 expression increasing VEGF-A release and activity in tumor microenvironment.

The telomeric protein TRF2 is overexpressed in several human malignancies and contributes to tumorigenesis even though the molecular mechanism is not completely understood. By using a high-throughput approach based on the multiplexed Luminex X-MAP technology, we demonstrated that TRF2 dramatically affects VEGF-A level in the secretome of cancer cells, promoting endothelial cell-differentiation and angiogenesis. The pro-angiogenic effect of TRF2 is independent from its role in telomere capping.

Quality and Correlates of Peer Relationships in Youths with Chronic Pain.

Youths with chronic pain may experience difficulties with peer relationships. We investigated the quality and correlates of peer relationships in a sample of 181 youths with chronic pain. A majority of youths were satisfied with their relationships with peers; however, levels were highly variable.

Epigenetic silencing of miR-296 and miR-512 ensures hTERT dependent apoptosis protection and telomere maintenance in basal-type breast cancer cells.

The catalytic subunit of the telomerase complex, hTERT, ensures unlimited proliferative potential of cancer cells by maintaining telomere function and protecting from apoptosis. Using a miRNA screening approach we identified miR-296-5p and miR-512-5p as miRNAs that target hTERT in breast cancer cells. Ectopic miR-296-5p and miR-512-5p reduce telomerase activity, drive telomere shortening and cause proliferation defects by enhancing senescence and apoptosis in breast cancer cells.

Altered telomere homeostasis and resistance to skin carcinogenesis in Suv39h1 transgenic mice.

The Suv39h1 and Suv39h2 H3K9 histone methyltransferases (HMTs) have a conserved role in the formation of constitutive heterochromatin and gene silencing. Using a transgenic mouse model system we demonstrate that elevated expression of Suv39h1 increases global H3K9me3 levels in vivo. More specifically, Suv39h1 overexpression enhances the imposition of H3K9me3 levels at constitutive heterochromatin at telomeric and major satellite repeats in primary mouse embryonic fibroblasts.

miR-155 drives telomere fragility in human breast cancer by targeting TRF1.

Telomeres consist of DNA tandem repeats that recruit the multiprotein complex shelterin to build a chromatin structure that protects chromosome ends. Although cancer formation is linked to alterations in telomere homeostasis, there is little understanding of how shelterin function is limited in cancer cells. Using a small-scale screening approach, we identified miR-155 as a key regulator in breast cancer cell expression of the shelterin component TERF1 (TRF1).
