Replication study of MATR3 in familial and sporadic amyotrophic lateral sclerosis

Authors: Claire Leblond, Ziv Gan-Or, Dan Spiegelman, Sandra Laurent, Anna Szuto, Alan Hodgkinson, Alexandre Dionne-Laporte, Pierre Provencher, Mamde de Carvalho, Sandro Orru, Denis Brunet, Jean-Pierre Bouchard, Philip Awadalla, Nicholas Dupre, Patrick Dion, Guy Rouleau

In this study, they looked at mutations of MATR3 (gene that is associated with ALS). They assessed the frequency in French Canadian populations and had a control group. They were able to determine which proteins are associated with ALS.

Comparison of the Effect of Thiazide Diuretics and Other Antihypertensive Drugs on Central Blood Pressure: Cross‐Sectional Analysis Among Nondiabetic Patients

Authors: Cristiano S. Moura, Stella S. Daskalopoulou, Linda E. Levesque, Sasha Bernatsky, Michal Abrahamowicz, Meytal A. Tsadok, Shadi Rajabi, Louise Pilote

This study used CARTaGENE data to determine to assess the noninferority of TDs relative to different classes of antihypertensive medications in relation to central blood pressure. No major differences were noted and it was shown that TDs are at least as effective as other first line medications that are available.

Neighborhood greenspace and health in a large urban center

Authors: Omid Kardan, Peter Gozdyra, Bratislav Misic, Faisal Moola, Lyle J. Palmer, Tomáš Paus & Marc G. Berman

This study focused on self-reported mental health study looked at the density of trees/green spaces in various neighbourhoods in Toronto. Those that had more trees reported that they were happier and felt better about their mental health.

Inherited chromosomally integrated human herpesvirus 6 as a predisposing risk factor for the development of angina pectoris

Authors: Annie Gravel, Isabelle Dubuc, Guillaum Morissette, Ruth Sedlak, Keith Jerome, Louis Flamand

It was found that in a study of 20,000 people our results showed that the prevalence of angina was 3 times more in iciHHV-6+ people than those who did not have a copy of the virus. It also showed that iciHHV-6+ may contribute to the development of angina.

Are Physical Activity Levels Linked to Nutrient Adequacy? Implications for Cancer Risk

Authors: I Cszimadi, LE Kelemen, T Speidel, Y Yuan, LC Dale, CM Friedenreich, PJ Robson

This study showed that higher PAL would promote better health and have DRIs which would help promote potential cancer-preventing nutrients. Benefits of higher PAIs may extend beyond the usual benefits attributed to physical activity.

Recombination affects accumulation of damaging and disease-associated mutations in human populations

Authors: Julie G Hussin, Alan Hodgkinson, Youssef Idaghdour, Jean-Christophe Grenier, Jean-Philippe Goulet, Elias Gbeha, Elodie Hip-Ki & Philip Awadalla

Using high-coverage sequencing data from over 1,400 individuals in the 1000 Genomes and CARTaGENE projects, we show that recombination rate modulates the distribution of putatively deleterious variants across the entire human genome.

Association of age-dependent height and bone mineral density decline with increased arterial stiffness and rate of fractures in hypertensive individuals

Authors: Rana EL-Bikai, Muhammad Tahir, Johanne Tremblay, Michel Joffres, Ondřej Šeda, Lucie Šedová, Philip Awadalla, Claude Laberge, Bartha-Maria Knoppers, Pierre Dumas, Daniel Gaudet, Louis-Georges Ste-Marie, Pavel Hamet

They wanted to determine if there was an association with height, arterial stiffness, and bone fractures. They were able to determine at the end of the study that those with shorter statures were more likely to have arterial stiffness and hypertension.

Leisure-Time Physical Activity Does not Attenuate the Association Between Occupational Sedentary Behavior and Obesity: Results From Alberta’s Tomorrow Project.

Authors: Joshua Nicholas, Geraldine Lo Siou, Brigid Lynch, Paula Robson, Christine Friedenrich, and Ilona Csizmadi

Using ATP data, this study determined that those in sedendary jobs are more at higher risk of obesity and was not attenuated by physical activity. Women did not show the same risk with sedendary behaviour.

The Sedentary Time and Activity Reporting Questionnaire (STAR-Q): reliability and validity against doubly labeled water and 7-day activity diaries.

Authors: Ilona Csizmadi, Heather K. Neilson, Karen A. Kopciuk, Farah Khandwala, Andrew Liu, Christine M. Friedenreich, Yutaka Yasui, Rémi Rabasa-Lhoret, Heather E. Bryant, David C. W. Lau, and Paula J. Robson

The research team put together a STAR-Q to estimate past-month energy expenditure. They looked at 102 adults over a two week period. The STAR-Q demonstrated substantial validity for estimating occupational sedentary time and strenuous activity and fair validity for ranking individuals by AEE.

Conditions Associated with Circulating Tumor-Associated Folate Receptor 1 Protein in Healthy Men and Women

Authors: Linda Keleman, James Brenton, Christine Parkinson, Hayley Whitaker, Anna Piskorz, Ilona Csizmadi, Paula Robson

This article examined how FOLR1 protein could potentially be way to detect early cancer. The team used electrochemical luminescence immunoassay. The study concluded that they should use caution when saying that serum FOLR1 can detect early cancer as there has not been a study with enough evidence to truly determine that.
