Diet in IBS Research Study

The Diet in IBS Research Study is a clinical crossover research study which is the first to investigate the effects of dietary gluten and amylase trypsin inhibitors (ATIs) on irritable bowel syndrome (IBS). The trial is being led by Drs. Premysl Bercik and M. Ines Pinto-Sanchez in the Farncombe Digestive Disease Research Institute at McMaster University. The Study Coordinator is PhD Candidate Caroline Seiler and the co-investigators include Dr. Elena Verdu, Dr. Stephen Collins, Dr. Paul Moayyedi, and Dr. Andrea Nardelli. This study is supported by the Canadian Digestive Health Foundation and a Society for the Study of Celiac Disease (SSCD) grant for Non-Celiac Gluten/Wheat Sensitivity sponsored by the Nestle Research Center, Nestec SA to Drs. Bercik and Pinto-Sanchez.

Benralizumab regulates atopic dermatitis through effects on eosinophils, basophils and innate lymphoid type 2 cells

There are not many medications available that are fully effective and can be used long-term for treatment of atopic dermatitis. Benralizimab is a monoclonal antibody used for treatment of a type of asthma called “eosinophilic asthma”. Atopic dermatitis is also associated with elevated levels of eosinophils, and we would like to determine if benralizumab is effective in patients with atopic dermatitis. 

This is a placebo-controlled study with 7 visits over 9 weeks.

The effect of sex hormone levels during the menstrual cycle on capsaicin evoked cough responses in mild allergic asthmatics.

All participants will undergo one screening visit to determine eligibility for the study, and 2 further subsequent visits. If you are a female participant on the oral contraceptive pill you will be assessed once between day 1-5 (during your pill break) and again between day 21-25. If you are a female participant with a natural cycle you will be assessed once between day 1 to day 5 of your menstrual cycle (i.e. during menstruation) and again between day 21-25 of your menstrual cycle. Men will be assessed in the same method, once between day 1 to 5, and once between day 21-25.

McMaster Institute for Infectious Disease Research COVID-19 Saliva-Protocol ImplemenTation Study

With this study, we aim to assess the success, impact, and practicality of saliva-based SARS-CoV-2/COVID-19 testing for scale up to include testing for large asymptomatic populations in a university laboratory setting. In addition to prevention of community, workplace, and school spread of SARS-CoV-2/COVID-19, we believe the impact of saliva-based routine testing on factors such as quality of life in the training/workplace environment will be substantially improved.

How are changes in the pacing and rhythm of language processed?

This study aims to investigate the role of rhythm and timing on how language is processed. As part of this study, participants will listen to auditory stimuli presented to them via earphones and watch a movie. Concurrently, EEG will be recorded to monitor their brain activity through electrodes placed on the scalp.
