Factors associated with change in moderate or severe symptoms of anxiety and depression in community-living adults and older adults during the COVID-19 pandemic

Authors: Helen-Maria Vasiliadis, Jessica Spagnolo, Mary Bartram, Marie-Josée Fleury, Jean-Philippe Gouin, Sébastien Grenier, Pasquale Roberge, Grace Shen-Tu, Jennifer E Vena, Catherine Lamoureux-Lamarche , JianLi Wang

Researchers explored changes in moderate or severe symptoms of anxiety or depression (MSSANXDEP) from before to during the COVID-19 pandemic in Canada, and examined associated sociodemographic, economic, psychosocial, health behavior and lifestyle, and clinical factors. Data from 59,997 participants from the five established cohorts of the Canadian Partnership for Tomorrow’s Health (CanPath) were used. Analyses indicated that certain sociodemographic, economic, lifestyle, health behavior, psychosocial, and clinical factors were associated with remitted, incident, and persistent MSSANXDEP.

Factors associated with mental health service use during the pandemic: Initiation and barriers

Authors: Helen-Maria Vasiliadis, Jessica Spagnolo, Marie-Josée Fleury, Jean-Philippe Gouin, Pasquale Roberge, Mary Bartram, Sébastien Grenier, Grace Shen-Tu, Jennifer E. Vena, JianLi Wang

This study aimed to understand the factors associated with initiating new mental health service use (MHSU) during the COVID-19 pandemic, as well as distinguishing between different reasons for not seeking mental health services. The research found that several factors influenced MHSU, such as age, living situation, income, and health professional status. The study suggests the need for awareness campaigns targeting older adults to explain the importance of seeking treatment and for sensitizing health professionals to facilitate access to mental health care for individuals at risk of social isolation and lower socioeconomic status.

Mental health service use and associated predisposing, enabling and need factors in community living adults and older adults across Canada

Authors: Helen-Maria Vasiliadis, Jessica Spagnolo, Marie-Josée Fleury, Jean-Philippe Gouin, Pasquale Roberge, Mary Bartram, Sébastien Grenier, Grace Shen-Tu, Jennifer E. Vena, JianLi Wang

The authors utilized data from the CanPath COVID-19 health survey (May to December 2020) to conduct multivariate logistic regression analysis to determine the association between mental health service use (MHSU) and predisposing, enabling, and need factors — derived from Andersen’s model of healthcare-seeking behaviour — among five regional cohorts. Among the 45,542 adults in the study population, 6.3% of respondents reported MHSU and need factors were consistently associated with MHSU.

Genetic analyses of DNA repair pathway associated genes implicate new candidate cancer predisposing genes in ancestrally defined ovarian cancer cases

Authors: Wejdan M Alenezi, Caitlin T Fierheller, Corinne Serruya, Timothée Revil, Kathleen K Oros, Deepak N Subramanian, Jeffrey Bruce, Dan Spiegelman, Trevor Pugh, Ian G Campbell, Anne-Marie Mes-Masson, Diane Provencher, William D Foulkes, Zaki El Haffaf, Guy Rouleau, Luigi Bouchard, Celia M T Greenwood, Jiannis Ragoussis, Patricia N Tonin

Researchers investigated families with a history of ovarian cancer that couldn’t be explained by known genetic risk factors. Using healthy controls from CARTaGENE, they applied a targeted gene approach and found rare genetic variants in DNA repair pathway genes, particularly in ERCC5, EXO1, FANCC, NEIL1, and NTHL1, in a significant portion of these families.

Molecular Genetic Characteristics of FANCI, a Proposed New Ovarian Cancer Predisposing Gene

Authors: Caitlin T Fierheller, Wejdan M Alenezi, Corinne Serruya, Timothée Revil, Setor Amuzu, Karine Bedard, Deepak N Subramanian, Eleanor Fewings, Jeffrey P Bruce, Stephenie Prokopec, Luigi Bouchard, Diane Provencher, William D Foulkes, Zaki El Haffaf, Anne-Marie Mes-Masson, Marc Tischkowitz, Ian G Campbell, Trevor J Pugh, Celia M T Greenwood, Jiannis Ragoussis, Patricia N Tonin

Researchers investigated the genetic characteristics of the FANCI gene, which has been linked to an increased risk of ovarian cancer. Using data from 171 CARTaGENE participants and other sources, they confirmed that a specific FANCI variant is associated with ovarian cancer and discovered potential genetic links to other cancer types.

The Genetic and Molecular Analyses of RAD51C and RAD51D Identifies Rare Variants Implicated in Hereditary Ovarian Cancer from a Genetically Unique Population

Authors: Wejdan M Alenezi, Larissa Milano, Caitlin T Fierheller, Corinne Serruya, Timothée Revil, Kathleen K Oros, Supriya Behl, Suzanna L Arcand, Porangana Nayar, Dan Spiegelman, Simon Gravel, Anne-Marie Mes-Masson, Diane Provencher, William D Foulkes, Zaki El Haffaf, Guy Rouleau, Luigi Bouchard, Celia M T Greenwood, Jean-Yves Masson, Jiannis Ragoussis, Patricia N Tonin

This study aimed to identify specific genetic mutations associated with increased risk of ovarian cancer. The mutations they discovered were found in many early-onset cases, particularly RAD51D, suggesting their role in hereditary ovarian cancer and the importance of the genes in the development of this disease.
