A Link Between Flu and Heart Attacks? Mass General Cardiologist Weighs In

Malissa Wood quoto.png

New research has found yet another reason to avoid catching the flu this season- it could increase your risk of a heart attack if you’re over the age of 35.

A recent study from investigators at the Institute for Clinical Evaluative Sciences and Public Health Ontario in Canada have found that you’re six times more likely to have a heart attack during the week after being diagnosed with the flu, compared to the year before or after the infection.

However, your chances of having a heart attack when you have the flu depends on your baseline risk. Most of the people who had a heart attack in this study were over the age of 65, and a lot of them had risk factors for heart disease, such as high blood pressure, high cholesterol or diabetes.

Malissa Wood, MD, Co-Director of the Corrigan Women’s Heart Health Program at Massachusetts General Hospital, says that these results confirm the connection between cardiovascular events, such as a heart attack, and respiratory infections like the flu.

“The flu is like a stress test for the heart,” says Wood in this NBC Boston news clip.

Of course, the best way to reduce your risk of flu-related health complications is to avoid getting the flu in the first place. Learn about preventative steps that you can take.

12 Days of Research at Mass General: An On-the-Go Test For Food Allergies

Banner 12 days of researchIn the 12 days leading up to our holiday hiatus, we are looking back on the past year and sharing some highlights in Massachusetts General Hospital research news from each month of 2017.

November 2017:

Pocket-Sized Device Provides Food Allergy Sufferers with Life-Saving Tableside Lab Results

If you’re among the 50 million Americans with a severe allergy to foods like gluten or nuts, every meal at a restaurant can feel like a potential land mine. Even if the restaurant has made an effort to provide dishes that are allergen-free, worries of cross-contamination and a subsequent severe or potentially life threatening reaction can still put a damper on your dinner plans.

To help ease concerns and keep food allergy sufferers safe, a team of researchers at Massachusetts General Hospital has developed a new device small enough to fit on a keyring that costs only $40 and can quickly and accurately test for food allergens.

While advances have been made in the packaged food industry, where new federal regulations require the manufacturer to disclose whether the product contains major food allergens, these disclosures are not always accurate and there are no similar regulations for the restaurant industry.

Rather than force diners to completely avoid foods that have the chance of containing an allergen, or eat something only to regret it later, Mass General researchers created integrated exogenous antigen testing (iEAT), a pocket-sized device that can accurately analyze food for the presences of allergens in less than 10 minutes. Specifically, the device can screen for peanuts, hazelnuts, wheat, milk and eggs.

The iEAT system

Developed by co-senior team leaders Ralph Weissleder, MD, PhD, Director of the Center for Systems Biology (CSB) at Mass General and Hakho Lee, PhD, Hostetter MGH Research Scholar and Director of the Biomedical Engineering Program at the CSB, the device consists of three components:

  1. A small plastic test tube that the user can put a small sample of food into. The tube contains a solution that dissolves the sample and adds magnetic beads to the solution. The beads are designed to bind to the food allergen of interest.
  2. The user can then drop the solution onto an electrode chip, which is inserted into the keychain sized reader.
  3. The reader analyzes the sample and indicates on a small display whether the allergen is present, and if so, in what concentration.

Testing performed by the research team showed that measurements of the concentration of the allergen is extremely accurate. In fact, the device could detect levels of gluten that were 200 times lower than the federal standard. Accuracy is key because everyone’s sensitivity varies — some individuals could experience a reaction after consuming a miniscule trace of an allergen.

Weissleder and Lee have also developed a smartphone app to complement iEAT. With the app, users can compile and store the data they collect as they test different foods for various allergens at different restaurants and even in packaged foods. The app is set up to share this information online so others with the app will be able to find restaurants with foods that consistently have no or low levels that are below the individual’s triggering concentration.

cell phone app

Consumers may be able to purchase the $40 iEAT device and corresponding app in the near future — the research team has granted a license to a local start-up company to make the system commercially available. Weissleder and Lee also report that they could apply this technology to detect other substances in food such as MSG or even pesticides.

This research was recently highlighted in an NIH article and published in ACS Nano.

It was also recently featured in a news story on CBS Boston.

Celebrity Patients Bring Lupus into The Headlines, But Much Remains Unknown

This September, actress and singer Selena Gomez announced on Instagram that she underwent a kidney transplant as part of her treatment for lupus, an autoimmune disease in which a body’s immune system begins to attack its own tissues and organs.

Gomez and other celebrities such as Nick Cannon, Toni Braxton and Seal have publicly spoken out about their struggles with lupus, which affects 1.5 million Americans and over five million people worldwide. Despite these high-profile patients, the disease still remains a mystery to much of the general public and the scientific community.

To shed light on symptoms, causes and treatment options for the disease, April Jorge, MD, a research fellow in the rheumatology unit at Massachusetts General Hospital , recently gave a talk on “Understanding the Mystery of Lupus” at Mass General’s Maxwell and Eleanor Blum Patient and Family Learning Center.

What is Lupus and Who Does it Affect?

The immune system typically protects us against infections by forming antibodies that detect and respond to invading pathogens, such as viruses and harmful bacteria. However, Jorge explained that in patients with lupus, the body forms auto-antibodies that target the own body’s cells as if they were intruders.

Lupus is a non-contagious and non-infectious disease that is caused by a combination of environmental and genetic factors. Jorge said that at least 50 different genes contribute to an increased risk of developing the disease.

Lupus is more common in women, and in African Americans and Hispanic populations. Patients are typically diagnosed between the ages of 15 to 45 years.

Symptoms of Lupus

Symptoms of lupus include skin rashes, hair loss, sores in the mouth, foggy thinking, seizures, vision problems, joint pain, liver inflammation, inflammation in the lining of the lungs and heart, blood clots, fatigue, and fever, among others.

“People with lupus also have a higher risk of heart attacks and strokes, and can be at a greater risk of getting osteoporosis and depression,” said Jorge. Lupus can also damage internal organs, especially the kidneys. Up to 50 percent of patients with lupus develop lupus nephritis—an inflammation of the kidneys that can prevent them from functioning properly.

Jorge suggested patients look out for several symptoms that may be warning signs of kidney damage.

“There can be some signs like swelling in the legs or belly,” she said. “Sometimes, it’s picked up by doctors if the patient has high blood pressure.” Other lupus patients may not have any outward symptoms of kidney damage, which makes it important for them to undergo regular screenings.


Jorge explained that the disease is so complex because signs and symptoms differ from person to person. Many times, symptoms of lupus overlap with those of other disorders. Hence, it takes an average of 6 years to obtain a lupus diagnosis.

Diagnosis is typically made by factoring in combination of symptoms, blood tests and other factors, such as impaired liver or kidney function as a result of inflammation.


While there is no cure for lupus, it is possible to treat the symptoms with medications and lifestyle changes.

Pharmaceutical Options

Medications prescribed for treating lupus include Prednisone (a corticosteroid that acts as an immune suppressant), Hydroxychloroquine (a drug originally used to treat malaria) and other immunosuppressant medications.

Currently doctors and scientists are trying to identify new and more effective treatments for lupus with fewer side effects. Jorge is optimistic about new drugs on the horizon that could improve treatment options. She said that biologics (products derived from natural—rather than chemical—sources) target certain parts of the immune system and are some of the most effective medications for lupus.

“Belimumab (manufactured under the brand name Benlysta®), which is given either as an injection or through an IV infusion, is the first drug to be approved for lupus in 50 years,” said Jorge. “But in the next five to 10 years, there will be many more.”

Lifestyle Modifications

Lifestyle changes can also help manage the symptoms of lupus, such as:

  • Exercising regularly
  • Getting enough sleep
  • Eating a healthy diet with fruits, vegetables and lean meats
  • Avoiding excess sun exposure
  • Using sunscreen lotions with at least SPF 50 and wearing protective clothing
  • Avoiding tobacco, as studies have indicated that smoking can make the disease more severe and harder to control

Based on recent research findings, the same strict guidelines may not apply to alcohol consumption. Jorge is currently investigating the impact of alcohol use on risk of heart attacks and death in patients with lupus. The research team has found that patients with lupus who consume light to moderate alcohol intake have lower rates of heart attacks and overall mortality than those who do not consume any alcohol.

Meet a Mass General Postdoc: Amy Tsurumi

In honor of National Postdoc Appreciation Week, all this week we’ll be sharing profiles of just a few of our amazing Mass General postdocs to highlight their research and what inspires them.

Postdoc week Tsurumi.png

Our fourth and final featured postdoc this year is Amy Tsurumi, PhD, a research fellow in the Rahme Lab.

Where did you get your PhD from?

University of Rochester School of Medicine and Dentistry

What questions are you asking in your current research? What do you hope to find out?

My research is elucidating epigenetic mechanisms of host susceptibility and response to infections using Drosophila, mice and tissue culture Pseudomonas aeruginosa infection models.  I hope to identify specific histone post-translational modification marks and genomic loci that are relevant and explore the possibility of alleviating the negative impact of pathogenic encounters by reversing these epigenetic marks.  Given the rise of antibiotic resistant bacteria, developing host-targeted methods as an alternative approach may be significant.  I also conduct epidemiological and biomarker studies for prediction of vulnerability to infections and infections-related outcomes in burn and trauma patient cohorts. 

What drew you to this field?

My father was a physician-scientist with a microbiology research background and fascination in human genetics, so I grew up being curious about the field of biomedical sciences.  As a graduate student, I learned about epigenetics for the first time and studied histone lysine demethylases, a relatively novel class of epigenetic regulators back then, which I found to be absolutely exciting.  I was thrilled to join the Rahme lab where I was lucky to have been given the opportunity to continue to conduct epigenetics research that I am interested in, but shift from the context of Drosophila development to host-microbe interactions using a variety of model organisms and also incorporate patient cohort clinical research.

What is a typical day like for you?

It is difficult to define a “typical” day, which I actually enjoy. Most days, I spend the majority of the time running experiments on the bench or conducting patient data analyses.  When there are grant/fellowship deadlines, I spend the day focusing on writing.  I find myself to be extremely lucky that there are many different types of experimental methods I get to do and various model organisms available in the Rahme lab.  The variety of techniques offered has given me an incredible learning experience thus far.

What do you like most about being a postdoc at MGH?

I am awed by the highly collaborative environment at MGH.  The Rahme lab is diverse in terms of scientific background (and home countries!) and I am very thankful to my mentor for the excellent mentorship and also to other postdocs around me, especially labmates and floormates for the invaluable input and help I receive daily.  I also feel fortunate to be part of collaborative projects with various PIs within MGH and around the globe, as well as the vast amount of resources offered by neighboring labs, MGH core facilities and other Harvard campuses.  All the research that goes on every day at MGH is stimulating and my mentor and colleagues I have the opportunity to work with are inspiring.

Meet a Mass General Postdoc: Robert Lochhead

This week is National Postdoc Appreciation Week, a time to recognize the significant contributions that postdoctoral scholars make to the research community.

In celebration, all this week we’ll be sharing profiles of just a few of the amazing postdocs here at Mass General to highlight their research and what inspires them.

First, we’d like to introduce Robert Lochhead, a clinical research fellow for the Center for Immunology and Inflammatory Diseases in the Division of Rheumatology, Allergy & Immunology:

Postdoc week Lochhead.png

Where did you get your PhD from?

I got my PhD in microbiology and immunology from the University of Utah School of Medicine.

What questions are you asking in your current research?

I am studying the immunopathology of Lyme arthritis, and the relationship between infection and autoimmunity.

What do you hope to find out?

From a microbial and immunological perspective, Lyme disease is a fascinating human infectious disease model. The pathogen, Borrelia burgdorferi, is highly adapted to hiding from the immune system within connective tissue, resulting in infections that can go undetected for many months. What’s more, there is a wide range of disease manifestations and severity, depending on both host and pathogen factors. Lyme arthritis, the most common late-disease manifestation, may persist or worsen even after the bacteria have been cleared by antibiotic therapy, called post-infectious Lyme arthritis. My research is focusing on how B. burgdorferi infection and subsequent tissue damage may trigger chronic autoimmune arthritis, with the hope of determining mechanisms of how infection may induce autoimmunity.

What drew you to this field?

As a young graduate student interested in host-pathogen interactions, I was attracted to the immunology of Lyme arthritis as a model of studying infection-induced autoimmunity. I’ve stuck with Lyme disease ever since, first in mouse models as a graduate student, now in humans as a postdoc.

What is a typical day like for you?

I spend most of my time analyzing big RNA sequencing datasets, in the microscope room, collecting and processing clinical samples, and writing grant applications and manuscripts. Right now my typical day is mostly writing.

What do you like most about being a postdoc at MGH?

Without a doubt, the best thing about being a postdoc here at MGH is the opportunity to collaborate with wonderful clinicians and patients who are so invested in the research side of human disease. Seeing the impact of these diseases on patients brings an urgency and focus to my research that will certainly shape the rest of my scientific career.

Evaluating the Impact of Cutbacks to HIV Programs in Resource-Limited Nations

Walensky quoto.png

Proposed reductions in U.S. foreign aid would have a devastating impact on HIV treatment and prevention programs in countries receiving such aid, an international team of investigators reports. In their paper published online in Annals of Internal Medicine, the team led by researchers at Massachusetts General Hospital and the Yale School of Public Health describes how a 33 percent cutback in funds earmarked for HIV/AIDS prevention, treatment and research in recent budget proposals would only save $900 per year of life lost in the countries of South Africa and Côte d’Ivoire.

Cuts to NIH Program Could Disrupt Infectious Disease Research at Mass General and Around the World

Mass General researchers working to stop the spread of infectious disease are worried that proposed cuts to the NIH budget would eliminate a key resource for global health efforts.

Back in the 1950s, there was a global effort to control mosquito populations with the hope of eradicating mosquito-borne diseases such as malaria and yellow fever. Unfortunately, the program was stopped before its goals could be met. Fast forward to the present where the issue of mosquito-borne diseases in some countries is much bigger than it was 50 years ago.

Investigators working to stop the spread of infectious disease around the world, including those at Massachusetts General Hospital, are worried that this same cycle could repeat itself if President Trump’s proposed cuts to the National Institutes of Health (NIH) budget are approved, which would eliminate the Fogarty International Center, a key resource for global health efforts.

“To avoid repeating the same mistake with infectious diseases, we must look ahead and provide the resources necessary now to find an answer to Ebola, HIV, cholera and many other diseases internationally,” explains Stephen Calderwood, MD, former Chief of the Division of Infectious Disease at Mass General.

“People are often unaware of what has been prevented, since by definition what has been prevented has not occurred,” adds Edward Ryan, MD, Director of Global Infectious Disease at Mass General. “The U.S. has and will continue to dodge bullets because of the Fogarty. We would be short-sighted to let this defensive wall fall.”

Closing the Fogarty could put an end to decades of progress into international infectious disease research, say advocates at Mass General. Moreover, doctors and scientists from at-risk countries could face even more barriers to conducting their own research and finding solutions that could directly benefit their communities and curb the spread of infectious diseases around the world.

Adhering to Treatment During Adolescence Keeps HIV-Positive Youth on Healthier Track

22384936 - hand holding yellow pills

As HIV therapies have improved in recent decades, we are now seeing the first generation of youth who were born with the disease, or acquired it shortly after birth, live to adulthood. As this population matures, researchers are looking to learn more about how these individuals have fared in managing their condition in order to improve long-term treatment and care.

A recent Massachusetts General Hospital study of 1,400 individuals between the ages of 7 and 30 born with HIV found that teens and young adults are more likely to have a difficult time managing their condition than they did as younger children. Those in the study group who had good HIV control generally experienced good overall health outcomes, while those who had poor HIV control – meaning higher levels of HIV virus and lower levels of CD4 immune cells had more physical and mental health conditions, a higher incidence of health complications, and a greater risk of death.

“Adolescents infected with HIV – either at birth or later in life – experience poorer health outcomes compared to adults with HIV in nearly every respect”, says Anne Neilan, MD, MPH, of the Division of Infectious Diseases and the Medical Practice Evaluation Center, who led the study. “We need to act to strengthen these services for youth, taking into account their developmentally specific needs. That might include youth-friendly services that consider the substantial stigma many of these patients face, novel approaches to antiretroviral therapy delivery, and improving support for youth transitioning from pediatric to adult health care providers.”

Andrea Ciaranello, MD, MPH, of the Massachusetts General Hospital Division of Infectious Diseases and the Medical Practice Evaluation Center, is senior author of the study. Anne Neilan, MD, MPH, of the Division of Infectious Diseases and the Medical Practice Evaluation Center, led the study. Read more about this study here.
