Five Years of Youth Engagement with Kids Help Phone Canada (Part 1): Phone, Chat, Text, and Peer-to-Peer Service Usage Nationally, Provincially, and Over Time.

Background: Child and youth mental health problems represent a substantial burden of illness in Canada, with appropriate services only inconsistently available. Charitable organizations, such as Kids Help Phone (KHP), are, therefore, crucial to filling system gaps by offering 24/7 phone, chat, texting, and peer-to-peer services. Methods: We describe the services provided by KHP, the volume of use for each service, and compare usage across Canada's provinces and territories for a 5-year period from January 2018 to December 2022. Trends seen during the COVID-19 pandemic are highlighted. Results: More than 1.5 million total number of conversations were held across texting, chat, and phone services over 5 years. Considerable growth is demonstrated between 2018 and 2022, and many of the highest peaks in volume occurred in March or April of 2020, the onset of the COVID-19 pandemic. The highest proportional volumes were consistently from the northern territories. Discussion: KHP cannot provide specialized or repeat services, nor can it alone meet the scale of unmet youth mental health needs across the country. Nonetheless, KHP plays a pivotal role in the Canadian mental health system. Efforts to understand the role that KHP and other e-mental health services like it play within the national mental health landscape should be intensified to aid in understanding unmet needs, identify system gaps, and make needed enhancements.

Five Years of Youth Engagement with Kids Help Phone Canada (Part 2): Issues Discussed Over Phone, Chat, Text, and Peer-to-Peer Services by Age Range.

Background: There is substantial unmet need for child and youth mental health problems in Canada. Charitable organizations, such as Kids Help Phone (KHP), are critical to filling system gaps, offering 24/7 e-mental health services outside the formal health care system. Methods: For the 5-year period from January 2018 to December 2022, we describe issues discussed by young people accessing KHP's services, and examine variations across different service platforms and age groups. Results: The most discussed issues across all service platforms and age groups were anxiety/stress, depression/sadness, and relationships. Suicide was most frequently discussed over text and Live Chat compared with other services, and was proportionally most discussed by young people 10-13 years of age on the phone and text services compared with other age ranges. Sexual abuse and violence were most frequently discussed by children 0-5 and 6-9 years of age across services. Discussion: Our analysis provides a unique snapshot into the concerns faced by children and youth across Canada, as well as the issues for which KHP is seen as an accessible place to seek support. Our findings can guide the future development of health promotion activities, and assist in new service development.

Integrated Transcriptome and Metabolomic Analysis Reveal Anti-Angiogenic Properties of Disarib, a Novel Bcl2-Specific Inhibitor.

Transcriptomic profiling of several drugs in cancer cell lines has been utilised to obtain drug-specific signatures and guided combination therapy to combat drug resistance and toxicity. Global metabolomics reflects changes due to altered activity of enzymes, environmental factors, etc. Integrating transcriptomics and metabolomics can provide genotype-phenotype correlation, providing meaningful insights into alterations in gene expression and its outcome to understand differential metabolism and guide therapy. This study uses a multi-omics approach to understand the global gene expression and metabolite changes induced by Disarib, a novel Bcl2-specific inhibitor in the Ehrlich adenocarcinoma (EAC) breast cancer mouse model. RNAseq analysis was performed on EAC mouse tumours treated with Disarib and compared to the controls. The expression of 6 oncogenes and 101 tumour suppressor genes interacting with Bcl2 and Bak were modulated upon Disarib treatment. Cancer hallmark pathways like DNA repair, Cell cycle, angiogenesis, and mitochondrial metabolism were downregulated, and programmed cell death platelet-related pathways were upregulated. Global metabolomic profiling using LC-MS revealed that Oncometabolites like carnitine, oleic acid, glycine, and arginine were elevated in tumour mice compared to normal and were downregulated upon Disarib treatment. Integrated transcriptomic and metabolomic profiles identified arginine metabolism, histidine, and purine metabolism to be altered upon Disarib treatment. Pro-angiogenic metabolites, arginine, palmitic acid, oleic acid, and myristoleic acid were downregulated in Disarib-treated mice. We further validated the effect of Disarib on angiogenesis by qRT-PCR analysis of genes in the VEGF pathway. Disarib treatment led to the downregulation of pro-angiogenic markers. Furthermore, the chorioallantoic membrane assay displayed a reduction in the formation of the number of secondary blood vessels upon Disarib treatment. Disarib reduces tumours by reducing oncometabolite and activating apoptosis and downregulating angiogenesis.
