Childhood maltreatment experiences are associated with future suicidal thoughts and suicide attempts, yet the roles of specific psychiatric symptoms mediating this relation remain to be clarified. To clarify these relations, we tested a model incorporating multiple forms of childhood maltreatment (sexual abuse, physical punishment, emotional neglect), past year psychiatric disorder symptoms during adolescence (anxiety, mood, and conduct disorders) and recent suicidal thoughts.

We administered structured interviews to 394 adolescents receiving outpatient substance use treatment services in the Southeastern United States (280 males; Mage=16.33; SDage=1.15). Structural equation models (SEMs) were used to evaluate the degree to which relations between childhood maltreatment and suicidal thoughts were mediated by specific past-year psychiatric symptoms.

Mood disorder symptoms significantly mediated the relation between neglect/negative home environment and suicidal thoughts. This path of influence did not vary by gender.

Childhood maltreatment and subsequent psychopathology influence suicidal thoughts among adolescents receiving substance use treatment services. The findings of the present study have implications for the adaptation and delivery of substance use treatment services to adolescents to enhance treatment engagement and outcomes.

A series of randomized controlled trials have investigated different first-line immunotherapy combinations, but the optimal combination strategy is yet to be established.

We performed a systematic review and Bayesian network meta-analysis by retrieving relevant literature from PubMed, EMBASE, Cochrane Library, ClinicalTrials.gov, andmajor international conferences. We included published and gray sources of randomized clinical trials comparing immunotherapy combinations with other treatments as first-line treatments for patients with advanced NSCLC. Thisstudy was registered in the Prospective Register ofSystematic Reviews (CRD42020210501) to ensure transparency.

We analyzed a total of 16 studies involving 8278 patients and including 10 immunotherapy combinations. For patients without programmed death-ligand 1 (PD-L1) selection, pembrolizumab plus chemotherapy was found to be comparable with sintilimab plus chemotherapy in providing the best overall survival (OS) benefit (hazard ratio= 0.96, 95% confidencith positive and negative PD-L1 expression, respectively. Although atezo-beva-chemo treatment provided the best progression-free survival and objective response rate, the addition of chemotherapy to immunotherapy would increase the toxicity, especially when antiangiogenesis drugs are simultaneously added.
Our results suggest that antiprogrammed death-1 combinations are associated with potentially higher survival outcomes than anti-PD-L1 combinations with comparable safety profiles. Moreover, pem-chemo and nivo-ipi-chemo seem to be superior first-line immunotherapy combinations for patients with advanced NSCLC with positive and negative PD-L1 expression, respectively. Although atezo-beva-chemo treatment provided the best progression-free survival and objective response rate, the addition of chemotherapy to immunotherapy would increase the toxicity, especially when antiangiogenesis drugs are simultaneously added.
Pulmonary invasive mucinous adenocarcinomas (IMAs) often present with spatially separate lung lesions. Clonal relationship between such lesions, particularly those involving contralateral lobes, is not well established. Here, we used comparative genomic profiling to address this question.

Patients with genomic analysis performed on two IMAs located in different lung regions were identified. Molecular assays included DNA-based next-generation sequencing (NGS) for 410 to 468 genes (Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets), RNA-based NGS for 62 genes (Memorial Sloan Kettering-Fusion), or non-NGS assays.

Comparative genomic profiling was performed on two separate IMAs in 24 patients, of whom 19 had contralateral lesions. Tumors from all but one patient shared matching driver alterations, including KRAS (n= 19), NRG1 (n= 2), ERBB2 (n= 1) or BRAF (n= 1). In addition, in patients with paired tumors profiled by NGS (n= 12), shared driver alterations were accompanied bonary spread arising from a single tumor and documents a subset with a remarkably protracted course of intrapulmonary progression. This study reinforces the unique biology and clinical behavior of IMAs while further highlighting the value of genomic testing for clarifying the clonal relationship between multiple lung carcinomas.
NRG1 rearrangements produce chimeric ligands that subvert the ERBB pathway to drive tumorigenesis. A better understanding of the signaling networks that mediate transformation by NRG1 fusions is needed to inform effective therapeutic strategies. Unfortunately, this has been hampered by a paucity of patient-derived disease models that faithfully recapitulate this molecularly defined cancer subset.

Patient-derived xenograft (PDX) and cell line models were established from NRG1-rearranged lung adenocarcinoma samples. Transcriptomic, proteomic, and biochemical analyses were performed to identify activated pathways. this website Efficacy studies were conducted to evaluate HER3- and MTOR-directed therapies.

We established a pair of PDX and cell line models of invasive mucinous lung adenocarcinoma (LUAD) (LUAD-0061AS3, SLC3A2-NRG1), representing the first reported paired invitro and invivo model of NRG1-driven tumors. Growth of LUAD-0061AS3 models was reduced by the anti-HER3 antibody GSK2849330. Transcriptomic profiling ric significance of which requires additional investigation.
We identify the MTOR pathway as a candidate vulnerability in NRG1 fusion-positive lung adenocarcinoma that may warrant further preclinical evaluation, with the eventual goal of finding additional therapeutic options for patients in whom ERBB-directed therapy fails. Moreover, our results uncover heterogeneity in downstream oncogenic signaling among NRG1-rearranged cancers, possibly tumor type-dependent, the therapeutic significance of which requires additional investigation.
