• Brock alumni invited to celebrate Homecoming from home

  Tuesday, September 15, 2020 | By Brock University

  MEDIA RELEASE: 15 September 2020 – R0138

  Like so many other big events on the post-secondary calendar this year, Brock University’s Homecoming Weekend will have a whole new approach.

  Rather than a typical weekend of in-person events, celebrations and reunions, Brock will kick off its Virtual Homecoming Launch with the theme of ‘keeping the tradition alive, no matter where you are in the world.’

  “Where Homecoming has been confined to a single weekend in the past, this year’s Homecoming Weekend will act as a launching pad for continued celebrations and programming throughout the rest of the year,” said Terry Cockerline, Director, Alumni Relations.

  The celebration will get started Friday, Sept. 18 with the unveiling of a Steel Blade Classic tribute website, which will feature highlights from the annual hockey game over the years, history about the Classic, photo galleries and more. The website will become accessible through the Brock Homecoming website on Friday.

  At 7 p.m., the tribute website will host the screening of a video looking back at the 2018 Steel Blade Classic — when a record crowd watched Brock beat the Guelph Gryphons at the Meridian Centre in downtown St. Catharines. The highlight video features commentary from head coach Marty Williamson, current player Adam Berg and former player Skylar Pacheco.

  On Saturday, Sept. 19, the flagship Virtual Alumni Recognition Reception will launch as a website featuring the annual alumni awards with videos of each Dean recognizing their Distinguished Faculty Graduate Award recipients and acceptance speeches for the winners.

  The site will also include remarks from Brock President Gervan Fearon, Brock University Alumni Association (BUAA) President Greg Plata, Director of Alumni Relations Terry Cockerline and BUAA Recognition of Excellence Committee Chair Allie Hughes.

  At 10 a.m. and 2 p.m. Saturday, alumni are invited to take part in live virtual campus tours. Spaces are limited and alumni are asked to register in advance here.

  Saturday will highlight Brock’s partnership with the Niagara Grape and Wine Festival, with the University serving as title sponsor of the Centre Stage Saturdays concert being livestreamed from 6 to 10 p.m. Brock Oenology and Viticulture alumni working in the wine industry will be featured throughout the broadcast.

  Brock alumni are encouraged to take part in a reunion photo contest being unveiled this weekend on the website to celebrate their one-, five-, 10-, 25- and 50-year anniversary milestones. The contest will run until Nov. 16 and anyone who takes part will be entered into a draw to win a variety of prizes.

  Badgers celebrating their silver (25-year) and golden (50-year) anniversaries with Brock are encouraged to request their cameo pins on the Homecoming website.

  For a full schedule of events and more information on future Homecoming events to be held throughout the fall, visit the Brock University Homecoming website.

• Canadian lung cancer prediction model proves effective at identifying at-risk African-Americans

  Monday, September 14, 2020 | By Brock University

  MEDIA RELEASE: 14 September 2020 – R0137

  The answer to reducing racial disparities in the occurrence of lung cancer could be found in a Canadian prediction model.

  A Brock University-designed lung cancer prediction model has been found to be more effective at identifying African-Americans who should be screened for lung cancer than what is currently available in the American health-care system.

  A study published recently found that Brock epidemiologist and Professor of Health Sciences Martin Tammemägi’s model identified up to 20 per cent more African-Americans who needed lung cancer screening than the United States Preventive Services Task Force (USPSTF) system.

  The data is considered more comprehensive because his model uses a greater number and broader criteria than the American system to determine who is eligible for lung cancer screening.

  “For a long time, it has been observed that African-Americans, in particular men, have elevated incidence of and mortality from lung cancer compared to white people and other racial or ethnic groups,” says Tammemägi, who is one of the study’s authors.

  The American Cancer Society attributes much of the difference to African-Americans’ “lower socioeconomic status and less access to medical care,” noting that “people with lower socioeconomic status face more barriers to high-quality health care, including lack of insurance.”

  But even when African-Americans do get pre-tested for lung cancer screening, they often fall through the cracks because the USPTF’s testing criteria “appear to be skewed toward white people, so disregarding race differences in lung cancer risk is expected to lead to under screening of African-American smokers, and exacerbate race disparities in lung cancer screening outcomes,” says the study.

  Two major U.S. organizations — the USPSTF and the Centers for Medicare and Medicaid Services (CMS) — have approved low-dose computed tomography (CT) lung cancer screening for high-risk individuals.

  CT lung cancer screening detects earlier stages of cancer, which are often cured by surgery. Without screening, most lung cancers are detected at an advanced stage, with most cases being fatal.

  To determine their eligibility for CT scanning, individuals are assessed according to a number of criteria. In the USPSTF and CMS models, people can receive CT scanning if they have smoked for 30 or more ‘pack-years,’ have quit within the last 15 years if they are former smokers, and if they are 55 to 80 years old in the USPSTF model or 55 to 77 years in the CMS model.

  A pack-year is smoking one package a day for one year or its equivalent, for example, smoking a half-pack a day for two years.

  The study calls the categorical pack-year/quit-time assessment approach a “comparatively crude measure” of someone’s actual risk.

  “In general, the USPSTF criteria is simplistic and narrow,” says Tammemägi.

  In contrast, Tammemägi’s model, dubbed PLCOm2012, uses 11 factors including the number of cigarettes smoked per day, the number of years of smoking, race/ethnicity, age, highest level of education obtained, family history of lung cancer, body mass index, among others — along with mathematical equations to predict the risk of an individual getting lung cancer.

  The model and associated risk calculators are posted on Brock’s Lung Cancer Risk Calculators website.

  Tammemägi says his model can identify African-Americans at a higher rate because the criteria are wide and numerous enough to capture their typical smoking behaviours.

  The study notes that African-American individuals are more likely to start smoking at a later age, smoke fewer cigarettes per day, have a longer duration of smoking, and are less likely to quit than their racial and ethnic counterparts.

  “Use of an accurate lung cancer risk prediction model, which accounts for the independent elevated risk in African-American individuals, can help overcome this disparity in lung cancer screening,” says the study.

  The research team, led by nurse practitioner Mary M. Pasquinelli at the University of Illinois at Chicago, calls for the USPSTF and CMS to modify their eligibility criteria so that more African-Americans can be screened with the goal of identifying those with the disease at an early stage.

  Canadian jurisdictions are slowly adapting a modified version — called the PLCO2012noRace model — of Tammemägi’s original model. For instance, Tammemägi is the Scientific Lead on a Cancer Care Ontario lung cancer screening pilot, which is now transitioning towards a province-wide program.

  Tammemägi says there is no evidence of a risk disparity with African-Canadians, “however, there may be a similar issue with our Indigenous population.”

  He is currently conducting research, funded by the Canadian Institutes of Health Research, looking at cancer screening in Ontario among First Nations and Métis peoples.

  More details can found in the team’s study, “Risk Prediction Model versus United States Preventive Services Task Force Lung Cancer Screening Eligibility Criteria – Reducing Race Disparities,” published in the Journal of Thoracic Oncology.

  Brock University Professor of Health Sciences Martin Tammemägi is available for media interviews.
