RESUMO
OBJECTIVE: To examine short-term (i.e., postintervention) outcomes from a randomized controlled trial comparing a school-based telehealth-delivered depression prevention program, Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), to services as usual (SAU). We expected IPT-AST would be acceptable and feasible and that IPT-AST adolescents would experience greater reductions in depression symptoms, anxiety symptoms, and impairment compared with SAU. METHOD: Adolescents (N = 242; Mage = 14.80 years, SD = 0.70; 65% female; 21% Black; 13% Hispanic/Latinx) with elevated scores on the Center for Epidemiologic Studies Depression Scale (Radloff, 1977) at screening provided data at baseline, 2-month (midpoint of IPT-AST), and 3-month (postintervention) assessments. They reported depression symptoms on the Center for Epidemiologic Studies Depression Scale, anxiety symptoms on the Screen for Child Anxiety Related Emotional Disorders (Birmaher et al., 1997), and impairment on the Columbia Impairment Scale (Bird et al., 1993). Baseline depression diagnosis was examined as a moderator. RESULTS: Hierarchical linear models showed that adolescents reported significant reductions in depression symptoms and impairment across conditions. IPT-AST adolescents reported significantly greater reductions in anxiety symptoms than SAU adolescents, d = .39, 95% CI [.05, .72], p = .003. Depression diagnosis moderated outcomes (ds = .33-.34, ps ≤ .05), such that IPT-AST adolescents without a diagnosis at baseline showed greater improvements in depression and anxiety symptoms than SAU adolescents. Adolescents in SAU with a depression diagnosis at baseline showed greater improvements in impairment compared with IPT-AST. Attendance and satisfaction data demonstrated the feasibility and acceptability of telehealth-delivered IPT-AST. CONCLUSIONS: Results support telehealth-delivered IPT-AST as a promising intervention for improving short-term outcomes among adolescents with depression symptoms but without a depression diagnosis.

RESUMO
Adolescence is a period of rapid social changes that may have important implications for the ways adolescents think, feel, and behave in their close relationships. According to family systems theory, adolescents' attachment-related changes have the potential to spread throughout their family system, leading to coordinated changes in parents' and adolescents' attachment styles over time. The present study analyzed data from 205 adolescents (MageT1 = 14.0, SD = 0.9; 44% female, 56% male; 51% White, 33% African American, 3% Hispanic/Latino, 1% Asian American, 12% another race/ethnicity) and their parents (196 mothers, 105 fathers; median household incomeT1 = $100,000) who completed self-report measures of their general attachment styles annually for 5 years. Using a latent growth curve framework, we examined the extent of coordination among adolescents' and parents' long-term trajectories and shorter term fluctuations in attachment security. The results revealed a push-and-pull dynamic between mothers' and adolescents' long-term trajectories of attachment security. Mothers who reported higher initial levels of attachment anxiety tended to have adolescent children who reported higher initial levels of avoidance. Additionally, adolescents who increased in attachment avoidance over time tended to have mothers who increased in attachment anxiety. Mothers and fathers mirrored each other's patterns of attachment security as their children navigated their teenage years, reporting similar initial levels of attachment avoidance and synchronized shorter term fluctuations in attachment anxiety and avoidance across time.

RESUMO
Importance: Lesbian, gay, bisexual, transgender, queer, and/or questioning (LGBTQ+) youth face worse mental health outcomes than non-LGBTQ+ peers. Family support may mitigate this, but sparse evidence demonstrates this in clinical settings. Objectives: To compare depression and suicide risk between LGBTQ+ and non-LGBTQ+ youth in primary care settings and to investigate whether family support mitigates these negative mental health outcomes. Design, Setting, and Participants: This cross-sectional study uses data from well care visits completed by adolescents aged 13 to 19 years from February 2022 through May 2023, including the Patient Health Questionnaire-9 Modified for Teens (PHQ-9-M) and the Adolescent Health Questionnaire (AHQ; an electronic screener assessing identity, behaviors, and guardian support), at 32 urban or suburban care clinics in Pennsylvania and New Jersey. Exposures: The primary exposure was self-reported LGBTQ+ status. Family support moderators included parental discussion of adolescent strengths and listening to feelings. Race and ethnicity (determined via parent or guardian report at visit check-in), sex, payer, language, age, and geography were covariates. Main Outcomes and Measures: PHQ-9-M-derived mental health outcomes, including total score, recent suicidal ideation, and past suicide attempt. Results: The sample included 60â¯626 adolescents; among them, 9936 (16.4%) were LGBTQ+, 15â¯387 (25.5%) were Black, and 30â¯296 (50.0%) were assigned female sex at birth. LGBTQ+ youth, compared with non-LGBTQ+ youth, had significantly higher median (IQR) PHQ-9-M scores (5 [2-9] vs 1 [0-3]; P < .001) and prevalence of suicidal ideation (1568 [15.8%] vs 1723 [3.4%]; P < .001). Fewer LGBTQ+ youth endorsed parental support than non-LGBTQ+ youth (discussion of strengths, 8535 [85.9%] vs 47â¯003 [92.7%]; P < .001; and listening to feelings, 7930 [79.8%] vs 47â¯177 [93.1%]; P < .001). In linear regression adjusted for demographic characteristics and parental discussion of strengths, LGBTQ+ status was associated with a higher PHQ-9-M score (mean difference, 3.3 points; 95% CI, 3.2-3.3 points). In logistic regression, LGBTQ+ youth had increased adjusted odds of suicidal ideation (adjusted odds ratio, 4.3; 95% CI, 4.0-4.7) and prior suicide attempt (adjusted odds ratio, 4.4; 95% CI, 4.0-4.7). Parental support significantly moderated the association of LGBTQ+ status with PHQ-9-M score and suicidal ideation, with greater protection against these outcomes for LGBTQ+ vs non-LGBTQ+ youth. Conclusions and Relevance: Compared with non-LGBTQ+ youth, LGBTQ+ youth at primary care visits had more depressive symptoms and higher odds of suicidal ideation and prior suicide attempt. Youth-reported parental support was protective against these outcomes, suggesting potential benefits of family support-focused interventions to mitigate mental health inequities for LGBTQ+ youth.

BACKGROUND: Talazoparib monotherapy in patients with germline BRCA-mutated, early-stage triple-negative breast cancer (TNBC) showed activity in the neoadjuvant setting in the phase II NEOTALA study (NCT03499353). These biomarker analyses further assessed the mutational landscape of the patients enrolled in the NEOTALA study. METHODS: Baseline tumor tissue from the NEOTALA study was tested retrospectively using FoundationOne®CDx. To further hypothesis-driven correlative analyses, agnostic heat-map visualizations of the FoundationOne®CDx tumor dataset were used to assess overall mutational landscape and identify additional candidate predictive biomarkers of response. RESULTS: All patients enrolled (N = 61) had TNBC. In the biomarker analysis population, 75.0% (39/52) and 25.0% (13/52) of patients exhibited BRCA1 and BRCA2 mutations, respectively. Strong concordance (97.8%) was observed between tumor BRCA and germline BRCA mutations, and 90.5% (38/42) of patients with tumor BRCA mutations evaluable for somatic-germline-zygosity were predicted to exhibit BRCA loss of heterozygosity (LOH). No patients had non-BRCA germline DNA damage response (DDR) gene variants with known/likely pathogenicity, based on a panel of 14 non-BRCA DDR genes. Ninety-eight percent of patients had TP53 mutations. Genomic LOH, assessed continuously or categorically, was not associated with response. CONCLUSION: The results from this exploratory biomarker analysis support the central role of BRCA and TP53 mutations in tumor pathobiology. Furthermore, these data support assessing germline BRCA mutational status for molecular eligibility for talazoparib in patients with TNBC.

Accumulating evidence supports the presence of a general psychopathology dimension, the p factor ('p'). Despite growing interest in the p factor, questions remain about how p is assessed. Although multi-informant assessment of psychopathology is commonplace in clinical research and practice with children and adolescents, almost no research has taken a multi-informant approach to studying youth p or has examined the degree of concordance between parent and youth reports. Further, estimating p requires assessment of a large number of symptoms, resulting in high reporter burden that may not be feasible in many clinical and research settings. In the present study, we used bifactor multidimensional item response theory models to estimate parent- and adolescent-reported p in a large community sample of youth (11-17 years) and parents (N = 5,060 dyads). We examined agreement between parent and youth p scores and associations with assessor-rated youth global functioning. We also applied computerized adaptive testing (CAT) simulations to parent and youth reports to determine whether adaptive testing substantially alters agreement on p or associations with youth global functioning. Parent-youth agreement on p was moderate (r =.44) and both reports were negatively associated with youth global functioning. Notably, 7 out of 10 of the highest loading items were common across reporters. CAT reduced the average number of items administered by 57%. Agreement between CAT-derived p scores was similar to the full form (r =.40) and CAT scores were negatively correlated with youth functioning. These novel results highlight the promise and potential clinical utility of a multi-informant p factor approach.
RESUMO
The genus Mixcoatlus is composed of three species: Mixcoatlus barbouri, M. browni, and M. melanurus, of which the venom composition of M. melanurus, the most common species of the three, has only recently been described. However, very little is known about the natural history of M. barbouri and M. browni, and the venom composition of these two species has remained thus far unexplored. In this study we characterize the proteomic profiles and the main biochemical and toxic activities of these two venoms. Proteomic data obtained by shotgun analysis of whole venom identified 12 protein families for M. barbouri, and 13 for M. browni. The latter venom was further characterized by using a quantitative 'venomics' protocol, which revealed that it is mainly composed of 51.1 % phospholipases A2 (PLA2), 25.5 % snake venom serine proteases (SVSP), 4.6 % l-amino oxidases (LAO), and 3.6 % snake venom metalloproteases (SVMP), with lower percentages other six protein families. Both venoms contained homologs of the basic and acidic subunits of crotoxin. However, due to limitations in M. barbouri venom availability, we could only characterize the crotoxin-like protein of M. browni venom, which we have named Mixcoatlutoxin. It exhibited a lethal potency in mice like that described for classical rattlesnake crotoxins. These findings expand knowledge on the distribution of crotoxin-like heterodimeric proteins in viper snake species. Further investigation of the bioactivities of the venom of M. barbouri, on the other hand, remains necessary.

-Phylogenomics allows us to uncover the historical signal of evolutionary processes through time and estimate phylogenetic networks accounting for these signals. Insight from genome-wide data further allows us to pinpoint the contributions to phylogenetic signal from hybridization, introgression, and ancestral polymorphism across the genome. Here, we focus on how these processes have contributed to phylogenetic discordance among rattlesnakes (genera Crotalus and Sistrurus), a group for which there are numerous conflicting phylogenetic hypotheses based on a diverse array of molecular datasets and analytical methods. We address the instability of the rattlesnake phylogeny using genomic data generated from transcriptomes sampled from nearly all known species. These genomic data, analyzed with coalescent and network-based approaches, reveal numerous instances of rapid speciation where individual gene trees conflict with the species tree. Moreover, the evolutionary history of rattlesnakes is dominated by incomplete speciation and frequent hybridization, both of which have likely influenced past interpretations of phylogeny. We present a new framework in which the evolutionary relationships of this group can only be understood in light of genome-wide data and network-based analytical methods. Our data suggest that network radiations, like those seen within the rattlesnakes, can only be understood in a phylogenomic context, necessitating similar approaches in our attempts to understand evolutionary history in other rapidly radiating species.

Despite a recent surge in high-throughput venom research that has enabled many species to be studied, some snake venoms remain understudied. The long-tailed rattlesnakes (Crotalus ericsmithi, C. lannomi, and C. stejnegeri) are one group where such research lags, largely owing to the rarity of these snakes and the hazardous areas, ripe with drug (marijuana and opium) production, they inhabit in Mexico. To fill this knowledge gap, we used multiple functional assays to examine the coagulotoxic (including across different plasma types), neurotoxic, and myotoxic activity of the venom of the long-tailed rattlesnakes. All crude venoms were shown to be potently anticoagulant on human plasma, which we discovered was not due to the destruction of fibrinogen, except for C. stejnegeri displaying minor fibrinogen destruction activity. All venoms exhibited anticoagulant activity on rat, avian, and amphibian plasmas, with C. ericsmithi being the most potent. We determined the mechanism of anticoagulant activity by C. ericsmithi and C. lannomi venoms to be phospholipid destruction and inhibition of multiple coagulation factors, leading to a net disruption of the clotting cascade. In the chick biventer assay, C. ericsmithi and C. lannomi did not exhibit neurotoxic activity but displayed potential weak myotoxic activity. BIRMEX® (Faboterápico Polivalente Antiviperino) antivenom was not effective in neutralising this venom effect. Overall, this study provides an in-depth investigation of venom function of understudied long-tailed rattlesnakes and provides a springboard for future venom and ecology research on the group.

OBJECTIVE: To test potential cognitive and interpersonal moderators of two evidence-based youth depression prevention programs. METHOD: Two hundred four adolescents (Mage = 14.62 years, SD = 1.65; 56% female; 71% White, 11% Black, 11% multiracial, 5% Asian, 2% other races, 18% Hispanic/Latinx) were randomized to either a cognitive-behavioral (Coping With Stress [CWS]) or interpersonal (Interpersonal Psychotherapy-Adolescent Skills Training [IPT-AST]) prevention program. Potential moderators, selected based on theory and research, included rumination, negative cognitive style, dysfunctional attitudes, hopelessness, parent-adolescent conflict, negative interactions with parents and friends, and social support from parents and friends. Depression symptoms were assessed repeatedly through 18 months postintervention. RESULTS: After adjusting for multiple comparisons, rumination (B = -2.02, SE = .61, p = .001, d = .47), hopelessness (B = -2.03, SE = .72, p = .005, d = .41), and conflict with father (B = 1.68, SE = .74, p = .02, d = .32) moderated intervention effects on change in depression symptoms from postintervention through 18-month follow-up. For example, at high levels of conflict with father, youth in IPT-AST reported a significant decrease in symptoms during follow-up, whereas youth in CWS reported a nonsignificant change in symptoms. At low levels of conflict with father, youth in IPT-AST reported a significant increase in symptoms during follow-up, whereas youth in CWS reported a nonsignificant change in symptoms. CONCLUSIONS: These exploratory secondary analyses of Personalized Depression Prevention study data highlight specific cognitive and interpersonal risk factors that could be considered when determining which prevention program may be most effective for a given adolescent.

Parents' responses to their children's negative emotions are a central aspect of emotion socialization that have well-established associations with the development of psychopathology. Yet research is lacking on potential bidirectional associations between parental responses and youth symptoms that may unfold over time. Further, additional research is needed on sociocultural factors that may be related to the trajectories of these constructs. In this study, we examined associations between trajectories of parental responses to negative emotions and adolescent internalizing symptoms and the potential role of youth sex and racial identity. Adolescents and caregivers (N = 256) completed six assessments that spanned adolescent ages 13-18 years. Multivariate growth models revealed that adolescents with higher internalizing symptoms at baseline experienced increasingly non-supportive parental responses over time (punitive and distress responses). By contrast, parental responses did not predict initial levels of or changes in internalizing symptoms. Parents of Black youth reported higher minimization and emotion-focused responses and lower distress responses compared to parents of White youth. We found minimal evidence for sex differences in parental responses. Internalizing symptoms in early adolescence had enduring effects on parental responses to distress, suggesting that adolescents may play an active role in shaping their emotion socialization developmental context.
RESUMO
Unique trajectories of adolescent depression symptoms have been identified, yet less is known about whether such patterns translate to real-world clinical settings. Because annual adolescent depression screening is becoming more prevalent in primary care, we examined whether longitudinal patterns of depression symptoms documented in the developmental psychopathology literature can also be detected via routine screening in primary care and explored how membership in the identified trajectories varied based on concurrent suicide risk and sociodemographic factors. A total of 1,359 adolescents aged 12-16 years old at the first timepoint were included in the current analyses. These adolescents completed three depression screeners during their well-visits in a large pediatric primary care network between November 15, 2017 and February 1, 2020. Retrospective electronic health record data were extracted, including sociodemographic variables and depression screening results. Dynamic functional time series clustering results indicated the optimal number of clusters was five. The five depression symptom trajectories were: (1) A-Shaped (i.e., relatively low depression symptoms at Time 1, a substantial increase in symptoms at Time 2, and a return to low symptoms at Time 3), (2) Increasing, (3) Low-Stable, (4) High-Decreasing, and (5) Low-Decreasing. Cluster differences in suicide risk largely mapped onto depression symptom levels at each assessment. We found cluster differences based on practice location, insurance type, and adolescent race. The symptom trajectories observed in this study resemble those found in the developmental psychopathology literature, though some key differences were noted. Findings can inform future research and symptom monitoring in primary care.

OBJECTIVE: The goal of the current study was to document patterns of stability and change in adolescent depression and suicide risk detected via universal depression screening in pediatric primary care and to determine who may go on to experience emerging risk. METHODS: Retrospective electronic health record information (sociodemographic data and depression screening results for 2 timepoints) was extracted for adolescents aged 12-17 who attended well-visits between November 15, 2017, and February 1, 2020, in a large pediatric primary care network. A total of 27,335 adolescents with 2 completed depression screeners were included in the current study. RESULTS: While most adolescents remained at low risk for depression and suicide across the 2 timepoints, others experienced emerging risk (i.e., low risk at time 1 but elevated risk at time 2), decreasing risk (i.e., high risk at time 1 but low risk at time 2) or stable high risk for depression or suicide. Odds of experiencing emerging depression and suicide risk were higher among adolescents who were female (compared to males), Black (compared to White), and had Medicaid insurance (compared to private insurance). Odds of experiencing emerging depression risk were also higher among older adolescents (compared to younger adolescents) as well as adolescents who identified as Hispanic/Latino (compared to non-Hispanic/Latino). CONCLUSIONS: Findings can inform symptom monitoring and opportunities for prevention in primary care.

RESUMO
Billions of dollars are being invested into developing medical artificial intelligence (AI) systems and yet public opinion of AI in the medical field seems to be mixed. Although high expectations for the future of medical AI do exist in the American public, anxiety and uncertainty about what it can do and how it works is widespread. Continuing evaluation of public opinion on AI in healthcare is necessary to ensure alignment between patient attitudes and the technologies adopted. We conducted a representative-sample survey (total N = 203) to measure the trust of the American public towards medical AI. Primarily, we contrasted preferences for AI and human professionals to be medical decision-makers. Additionally, we measured expectations for the impact and use of medical AI in the future. We present four noteworthy results: (1) The general public strongly prefers human medical professionals make medical decisions, while at the same time believing they are more likely to make culturally biased decisions than AI. (2) The general public is more comfortable with a human reading their medical records than an AI, both now and "100 years from now." (3) The general public is nearly evenly split between those who would trust their own doctor to use AI and those who would not. (4) Respondents expect AI will improve medical treatment but more so in the distant future than immediately.

ABSTRACT: BACKGROUND: Stroke is a medical emergency requiring timely intervention to optimize patient outcomes. The only treatments currently Food and Drug Administration approved for acute stroke are intravenous (IV) thrombolytics, which require obtaining specific medical history to be administered safely. This medical history may be overlooked in the prehospital setting or lost during patient handoff between emergency medical services (EMS) personnel and hospital staff, delaying treatment. We evaluated whether utilization of a "stroke alert sticker" by EMS to capture key information in the field would decrease door-to-needle (DTN) time. METHODS: Bright-orange "stroke alert stickers" were disseminated to our local EMS agency to be placed on all suspected stroke patients in the field prompting documentation of key elements needed for timely treatment decisions. The "stroke alert sticker" included time last known well, contact information, presenting symptoms, and relevant medications. We evaluated the impact of the "stroke alert sticker" on acute stroke metrics, including DTN time. RESULTS: The project included 220 consecutive stroke alert patients brought to our comprehensive stroke center by a single EMS agency from May 2021 through February 2022. Twenty-one patients were treated with an IV thrombolytic. Overall "stroke alert sticker" use compliance was 40%; for the subgroup of patients who were given an IV thrombolytic, the "stroke alert sticker" was used 60% of the time. In patients who received an IV thrombolytic, prehospital EMS notification was 100% with "stroke alert sticker" use, compared with 75% without (P = .13). In addition, with "stroke alert sticker" utilization, DTN time was reduced by 20 minutes (31 [11] minutes with sticker vs 51 [21] minutes without, P = .04). CONCLUSION: Utilization of the "stroke alert sticker" significantly improved DTN times compared with patients without the sticker. This evidence supports continued use of the "stroke alert sticker" to improve DTN times and patient outcomes.

ABSTRACT: Spindle cell-predominant trichodiscoma (SCPT) is a benign adnexal neoplasm, best categorized within the trichodiscoma-fibrofolliculoma continuum. SCPTs clinically present as dome-shaped papules usually on the face, particularly on the nose or the nasolabial fold. The SCPT variant has been described as a particularly cellular trichodiscoma composed of small interweaving fascicles and sheets of spindle cells. Identical lesions were previously referred to as neurofollicular hamartomas because of their predominantly fascicular stromal cellularity and focal S100 positivity. In this article, we report a rare variant of SCPT with a palisaded arrangement. The patient is a middle-aged man with no significant dermatologic history who presented with a skin-colored papule on the left nasal ala. It had been present for approximately 10 years with only minimal growth over that time. A biopsy was obtained. Histopathological analysis revealed a dermal papule composed of bland spindle cells arranged in a striking palisading pattern within a fibromyxoid stroma with associated peripheral hyperplasia of sebaceous glands. The palisaded pattern shared features reminiscent of Verocay bodies of a schwannoma. Immunohistochemical studies revealed stromal spindled cells with a strong and diffuse pattern of CD34 expression and absent S100 and SOX10 expressions. To our knowledge, only 2 cases of SCPT with a palisaded pattern have been presented. SCPT with a palisaded pattern is a rare histopathologic variant that may resemble a schwannoma but can be recognized by its strong epithelial components and immunohistochemical staining pattern.

The growing discovery and development of novel radiopharmaceuticals and radiolabeling methods requires an increasing capacity for radiochemistry experiments. However, such studies typically rely on radiosynthesizers designed for clinical batch production rather than research, greatly limiting throughput. Two general solutions are being pursued to address this: developing new synthesis optimization algorithms to minimize how many experiments are needed, and developing apparatus with enhanced experiment throughput. We describe here a novel high-throughput system based on performing arrays of droplet-based reactions at 10 µL volume scale in parallel. The automatic robotic platform can perform a set of 64 experiments in ~3 h (from isotope loading to crude product, plus sampling onto TLC plates), plus ~1 h for off-line radio-TLC analysis and radioactivity measurements, rather than the weeks or months that would be needed using a conventional system. We show the high repeatability and low crosstalk of the platform and demonstrate optimization studies for two 18F-labeled tracers. This novel automated platform greatly increases the practicality of performing arrays of droplet reactions by eliminating human error, vastly reducing tedium and fatigue, minimizing radiation exposure, and freeing up radiochemist time for other intellectually valuable pursuits.
RESUMO
BACKGROUND: The undetermined efficacy of the current standard-of-care neoadjuvant treatment, anthracycline/platinum-based chemotherapy, in patients with early-stage triple-negative breast cancer (TNBC) and germline BRCA mutations emphasizes the need for biomarker-targeted treatment, such as poly(ADP-ribose) polymerase inhibitors, in this setting. This phase II, single-arm, open-label study evaluated the efficacy and safety of neoadjuvant talazoparib in patients with germline BRCA1/2-mutated early-stage TNBC. PATIENTS AND METHODS: Patients with germline BRCA1/2-mutated early-stage TNBC received talazoparib 1 mg once daily for 24 weeks (0.75 mg for moderate renal impairment) followed by surgery. The primary endpoint was pathologic complete response (pCR) by independent central review (ICR). Secondary endpoints included residual cancer burden (RCB) by ICR. Safety and tolerability of talazoparib and patient-reported outcomes were assessed. RESULTS: Of 61 patients, 48 received ≥80% talazoparib doses, underwent surgery, and were assessed for pCR or progressed before pCR assessment and considered nonresponders. pCR rate was 45.8% (95% confidence interval [CI], 32.0%-60.6%) and 49.2% (95% CI, 36.7%-61.6%) in the evaluable and intent-to-treat (ITT) population, respectively. RCB 0/I rate was 45.8% (95% CI, 29.4%-63.2%) and 50.8% (95% CI, 35.5%-66.0%) in the evaluable and ITT population, respectively. Treatment-related adverse events (TRAE) were reported in 58 (95.1%) patients. Most common grade 3 and 4 TRAEs were anemia (39.3%) and neutropenia (9.8%). There was no clinically meaningful detriment in quality of life. No deaths occurred during the reporting period; 2 deaths due to progressive disease occurred during long-term follow-up (>400 days after first dose). CONCLUSIONS: Neoadjuvant talazoparib monotherapy was active despite pCR rates not meeting the prespecified threshold; these rates were comparable to those observed with combination anthracycline- and taxane-based chemotherapy regimens. Talazoparib was generally well tolerated. CLINICALTRIALS.GOV IDENTIFIER: NCT03499353.

PURPOSE: Researchers and service providers typically assess pediatric Health-Related Quality of Life (HRQOL) by collecting independent reports from parents and youth. An emerging body of work indicates that patterns of parent-youth reports yield information germane to understanding youth outcomes. We identified patterns of HRQOL among youth and their parents seeking mental health treatment and examined links between agreement patterns and mental and physical health functioning. METHODS: Participants included 227 youth (mean age = 14.40 years, SD = 2.42; 63% female) and parent dyads presenting at a mood disorders clinic between 2013 and 2020. We assessed HRQOL using parallel youth and parent forms of the Pediatric Quality of Life Inventory Generic Core Scales. We also assessed youth clinical correlates of depression, suicidal ideation, and impairment, as well as health information via electronic health record (e.g., psychotropic medication usage, BMI). RESULTS: Latent class analysis showed three parent-youth reporting patterns: Low-Low (LL), High-High (HH), and Parent Low-Youth High (PL-YH). Relative to youth in the HH group, youth in the LL and PL-YH groups reported significantly greater depressive symptoms and had higher rates of suicidal ideation and psychotropic medication use. In addition, youth in the LL group reported significantly greater levels of impairment. CONCLUSIONS: Parent-youth patterns of HRQOL reporting can reveal clinically meaningful information and indicate poorer functioning for certain groups (LL, PL-YH) of youth. These findings have implications for improving accuracy of risk assessments that leverage HRQOL data.
