Anxiety, for instance, is one of the top reasons for visits to family doctors in every age group, and the top reason for adult females. Chronic diseases 鈥 the greatest health challenge facing Canada and much of the world 鈥 are also increasingly managed by family doctors.</p> <p>Using data from the de-identified electronic medical record data of nearly half-a-million patients, the report is the first evidence-based, comprehensive picture of the role of family doctors in our health-care system and provides new insights into the health and wellbeing of the citizens of Toronto and beyond.</p> <p>鈥淭his report reinforces the findings of international studies which show that having family medicine as the basis of a country鈥檚 health-care system keeps people healthier, reduces costs and ensures more equitable access to care,鈥 says Dr. <strong>Michael Kidd</strong>, chair of 老司机直播鈥檚 department of family and community medicine and one of the authors of the report.</p> <p>鈥淎s we start to roll out Ontario Health Teams, this report provides timely evidence and insights into the central role of family doctors, and the members of our teams, in our health-care system.鈥</p> <p>Beyond the treatment of common illnesses, many family doctors in Ontario deliver babies, work in emergency departments, provide palliative and end of life care, participate in research and innovation and much more. The diversity of patients and ailments seen by family doctors is quickly changing as well.</p> <p>鈥淭he data in this report confirmed a number of trends we are seeing in health care,鈥 says Dr. <strong>Karen Tu</strong>, lead author of the report, a co-director of the University of Toronto Practice-based Research Network and a professor in the department of family and community medicine with a cross appointment at the Institute of Health Policy Management and Evaluation.</p> <p>鈥淢ental health and chronic diseases are being treated by family doctors far more frequently. We are also continuing to see high rates of smoking and obesity, so it鈥檚 key to find new ways to help family doctors treat and support patients with these concerns.鈥</p> <p>The report also highlights areas of care where family doctors can play an even larger role. For instance, only 63 per cent of Indigenous people living in Toronto have a regular family doctor or nurse practitioner, compared to 90 per cent of the general population. The report also tackles issues like the lack of access to palliative care by marginalized populations in the Greater Toronto Area, the health concerns of refugees and what family doctors are doing to address the ongoing opioid crisis.</p> <p>鈥淣ot everyone knows or appreciates the breadth of services family doctors provide and the value family medicine brings to our health-care system,鈥 says Kidd.</p> <p>鈥淔amily medicine provides the solution to overcrowded emergency departments, the challenge of hallway medicine in our hospitals, and the inequities we see in access to quality health-care services.</p> <p>鈥淭his report highlights the importance of family medicine as the foundation of a successful health-care system and reinforces the need for further investment in primary care to ensure that quality health care is available to all Canadians.鈥</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 17 May 2019 16:25:49 +0000 Christopher.Sorensen 156714 at More than 300,000 Canadians enrol in multi-decade research initiative to monitor disease trends /news/more-300000-canadians-enrol-multi-decade-research-initiative-monitor-disease-trends <span class="field field--name-title field--type-string field--label-hidden">More than 300,000 Canadians enrol in multi-decade research initiative to monitor disease trends</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2018-06-18-genome-resized.jpg?h=afdc3185&amp;itok=bb6EzshK 370w, /sites/default/files/styles/news_banner_740/public/2018-06-18-genome-resized.jpg?h=afdc3185&amp;itok=36-nWMjJ 740w, /sites/default/files/styles/news_banner_1110/public/2018-06-18-genome-resized.jpg?h=afdc3185&amp;itok=GzQY2KRy 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2018-06-18-genome-resized.jpg?h=afdc3185&amp;itok=bb6EzshK" alt="Photo of John McLaughlin, Cindy Morton and Philip Awadalla"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>noreen.rasbach</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2018-06-18T00:00:00-04:00" title="Monday, June 18, 2018 - 00:00" class="datetime">Mon, 06/18/2018 - 00:00</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">From left, Dr. John McLaughlin, executive director of CPTP, Cindy Morton, chief executive officer of the Canadian Partnership Against Cancer, and Dr. Philip Awadalla, national scientific director of CPTP</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/nicole-bodnar" hreflang="en">Nicole Bodnar</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/global-lens" hreflang="en">Global Lens</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/cancer" hreflang="en">Cancer</a></div> <div class="field__item"><a href="/news/tags/chronic-illness" hreflang="en">Chronic Illness</a></div> <div class="field__item"><a href="/news/tags/dalla-lana-school-public-health" hreflang="en">Dalla Lana School of Public Health</a></div> <div class="field__item"><a href="/news/tags/faculty-medicine" hreflang="en">Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/genetics" hreflang="en">Genetics</a></div> <div class="field__item"><a href="/news/tags/global" hreflang="en">Global</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp;

More than 80 scientific programs have already begun research with CPTP, and received independent funding from national and international funders. A study published earlier this year in <em>Nature Communications</em> showed how environmental exposures interact with our genomes to impact health. The CPTP scientists involved in the study will also use the cohort to answer questions about why cancer rates vary across the country (B.C. has much lower rates of certain types of cancers compared to Atlantic Canada).</p> <p>Awadalla and colleagues have received funding from the Canadian Institutes of Health Research to examine metabolic syndrome, which includes a range of conditions like high blood pressure, Type 2 diabetes, glucose intolerance and cardiovascular disease.

The discovery is a potential game-changer for the treatment of chronic illnesses or injuries that often require multiple injections or daily pills.</p> <p>For decades, biomedical engineers have been painstakingly encapsulating proteins in nanoparticles to control their release. Now, a research team, all from the department of Chemical Engineering &nbsp;and the Institute of Biomaterials and Biomedical Engineering,&nbsp;led by University Professor <strong>Molly Shoichet</strong>&nbsp;has shown that proteins can be released over several weeks, even months, without ever being encapsulated. In this case the team looked specifically at therapeutic proteins relevant to tissue regeneration after stroke and spinal cord injury.&nbsp;</p> <p>鈥淚t was such a surprising and unexpected discovery,鈥 said co-lead author and recent PhD graduate&nbsp;<strong>Irja Elliott Donaghue</strong>, who first found that the therapeutic protein NT3, a factor that promotes the growth of nerve cells, was slowly released when just mixed into a Jello-like substance that also contained nanoparticles. 鈥淥ur first thought was, 鈥榃hat could be happening to cause this?鈥欌</p> <p>Proteins hold enormous promise to treat chronic conditions and irreversible injuries 鈥 for example, human growth hormone is encapsulated in these tiny polymeric particles, and used to treat children with stunted growth. In order to avoid repeated injections or daily pills, researchers use complicated strategies both to deliver proteins to their site of action, and to ensure they鈥檙e released over a long enough period of time to have a beneficial effect.</p> <p>This has long been a major challenge for protein-based therapies, especially because proteins are large and often fragile molecules. Until now, investigators have been treating proteins the same way as small drug molecules and encapsulating them in polymeric nanoparticles, often made of a material called poly(lactic-co-glycolic acid) or PLGA.</p> <p>As the nanoparticles break down, the drug molecules escape. The same process is true for proteins; however, the encapsulating process itself often damages or denatures some of the encapsulated proteins, rendering them useless for treatment. Skipping encapsulation altogether means fewer denatured proteins, making for more consistent protein therapeutics that are easier to make and store.</p> <p>鈥淭his is really exciting from a translational perspective,鈥 said PhD student&nbsp;<strong>Jaclyn Obermeyer</strong>. 鈥淗aving a simpler, more reliable fabrication process leaves less room for complications with scale-up for clinical use.鈥</p> <p>The three lead authors, Elliott Donoghue, Obermeyer and 2016 PhD graduate&nbsp;<strong>Malgosia Pakulska</strong>,&nbsp;have shown that to get the desired controlled release, proteins only need to be alongside the PLGA nanoparticles, not inside them. Their work was published recently in the journal <a href="http://advances.sciencemag.org/content/2/5/e1600519"><em>Science Advances</em></a>.</p> <p>鈥淲e think that this could speed up the path for protein-based drugs to get to the clinic,鈥 said Elliott Donaghue.</p> <p>The mechanism for this encapsulation-free controlled release is surprisingly elegant. Shoichet鈥檚 group mixes the proteins and nanoparticles in a Jello-like substance called a hydrogel, which keeps them localized when injected at the site of injury. The positively charged proteins and negatively charged nanoparticles naturally stick together. As the nanoparticles break down they make the solution more acidic, weakening the attraction and letting the proteins break free.</p> <p>鈥淲e are particularly excited to show long-term, controlled protein release by simply controlling the electrostatic interactions between proteins and polymeric nanobeads,鈥 said Shoichet. 鈥淏y manipulating the pH of the solution, the size and number of nanoparticles, we can control release of bioactive proteins. This has already changed and simplified the protein release strategies that we are pursuing in pre-clinical models of disease in the brain and spinal cord.鈥</p> <p>鈥淲e鈥檝e learned how to control this simple phenomena,鈥 Pakulska said. 鈥淥ur next question is whether we can do the opposite鈥攄esign a similar release system for positively charged nanoparticles and negatively charged proteins.鈥</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 07 Jun 2016 15:54:14 +0000 katie.fong 14211 at
