Prediction of Cardiovascular Events by Pulse Waveform Parameters: Analysis of CARTaGENE

Authors: Louis-Charles Desbiens, Catherine Fortier, Annie-Claire Nadeau-Fredette, François Madore, Bernhard Hametner, Siegfried Wassertheurer, Mohsen Agharazii, Rémi Goupil

Researchers conducted the largest study to date evaluating non-invasive pulse waveform parameters’ association with cardiovascular events. By adding two waveform parameters to the existing atherosclerotic cardiovascular disease score, they improved cardiovascular prediction and reclassified up to 5.7% of patients in another risk category.

Cohort Profile: The Ontario Health Study (OHS)

Authors: Victoria A Kirsh, Kimberly Skead, Kelly McDonald, Nancy Kreiger, Julian Little, Karen Menard, John McLaughlin, Sutapa Mukherjee, Lyle J Palmer, Vivek Goel, Mark P Purdue, Philip Awadalla

OHS’s cohort profile outlines its research platform’s history and value for the broader scientific community. OHS follows 225,000 over their lifetime, actively and passively, making de-identified genomic, environmental, lifestyle, and electronic health data available to cancer and chronic disease researchers.

Arsenic Speciation and Metallomics Profiling of Human Toenails as a Biomarker to Assess Prostate Cancer Cases: Atlantic PATH Cohort Study

Authors: Erin Keltie, Kalli M Hood, Yunsong Cui, Ellen Sweeney, Gabriela Ilie, Anil Adisesh, Trevor Dummer, Veni Bharti, Jong Sung Kim

This study aimed to characterize arsenic species and metallome profiles in toenails and urine samples, compare these profiles between prostate cancer cases and controls, and evaluate the utility of toenail and urine biomarkers. Toenails were found to be viable biomarkers for altered arsenic speciation in prostate cancer cases.

Associations between neighbourhood street connectivity and sedentary behaviours in Canadian adults: Findings from Alberta’s Tomorrow Project

Authors: Vikram Nichani, Mohammad Javad Koohsari, Koichiro Oka, Tomoki Nakaya, Ai Shibata, Kaori Ishii, Akitomo Yasunaga, Jennifer E Vena, Gavin R McCormack

Researchers aimed to estimate associations between street connectivity, based on space syntax-derived street integration, and sedentary behaviours. Using data from 14,758 Alberta’s Tomorrow Project participants, they found that connectivity was positively related to various measures of sitting time and negatively associated with motor vehicle travel time.

Developing a Socioeconomic Status Index for Chronic Disease Prevention Research in Canada

Authors: Elham Khodayari Moez, Katerina Maximova, Shannon Sim, Ambikaipakan Senthilselvan, Roman Pabayo

Researchers developed a socioeconomic status (SES) index and assessed its associations with smoking amongst 17,371 Alberta’s Tomorrow Project participants. They found that their index was negatively related to smoking intensity.

Cross-sectional and longitudinal associations between the built environment and walking: effect modification by socioeconomic status

Authors: Chelsea D Christie, Christine M Friedenreich, Jennifer E Vena, Liam Turley, Gavin R McCormack

Using data from 703 Alberta’s Tomorrow Project participants, researchers found that changes to the built environment are not associated with changes in walking amongst adults after relocation. They also had weak findings that changes in walkability due to relocation may more strongly affect walking for adults with lower socioeconomic status.

Substituting bouts of sedentary behavior with physical activity: adopting positive lifestyle choices in people with a history of cancer

Authors: Lee Ingle, Samantha Ruilova, Yunsung Cui, Vanessa DeClercq, Ellen Sweeney, Zhijie Michael Yu, Cynthia C Forbes

This study aimed to determine the association between substituting sitting time with other daily activities and changes in waist circumference amongst people with cancer history. The researchers found that small changes to minimize their sitting time help reduce waist circumference, possibly offsetting other adverse health outcomes.

Anti-Hyperglycemic Medication Adherence and Health Services Utilization in People with Diabetes: A Longitudinal Study of Alberta’s Tomorrow Project

Authors: Ming Ye, Jennifer E Vena, Jeffrey A Johnson, Grace Shen-Tu, Dean T Eurich

This study aimed to describe how time-varying anti-hyperglycemic medication adherence relates to healthcare utilization for those with diabetes. Using data from Alberta’s Tomorrow Project participants, researchers found that poor drug adherence related to higher healthcare utilization in the short term but less over the long term.

Applying Machine Learning to Arsenic Species and Metallomics Profiles of Toenails to Evaluate Associations of Environmental Arsenic with Incident Cancer Cases

Authors: Sheida Majouni, Jong Sung Kim, Ellen Sweeney, Erin Keltie, Syed Sibte Raza Abidi

This preliminary study aimed to understand the association between environmental metal pathogenicity and carcinogenicity and prostate cancer. Researchers used toenails to capture arsenic exposure!

Analyzing cohort studies with interval-censored data: A new model-based linear rank-type test

Authors: Rodolphe Jantzen, Pascale Tubert-Bitter, Philippe Broët

When analyzing cohort studies with interval-censored data, the researchers suggest that statisticians employ their proposed test to test survival distributions’ quality between two or more groups.
