What does HAROLD CANNON research?

Mr. Cannon studies a variety of serious health conditions including myocarditis related to COVID-19, cardiac arrest outcomes, and the management of hereditary hemochromatosis. He investigates how certain treatments, like epinephrine during cardiac arrest or phlebotomy for iron overload, can significantly impact patient recovery and survival. He also explores healthcare practices internationally, such as the use of endovascular therapy in stroke patients, to identify best practices and enhance treatment consistency.

Key findings

  • Mr. Cannon found that 11.7% of COVID-19 patients with myocarditis were readmitted to the hospital within 30 days, primarily due to patients leaving against medical advice.
  • His research showed that administering a single dose of epinephrine improved survival rates by 61% for cardiac arrest patients who received bystander CPR.
  • In an international survey, he discovered that 48% of doctors offered endovascular therapy to mild stroke patients presenting within 6 hours, highlighting variability in treatment approaches across countries.
  • Among 210 patients with hereditary hemochromatosis, 60% reported fatigue and 50% joint pain, with many finding phlebotomy treatment beneficial despite experiencing side effects.

Does Single Dose Epinephrine Improve Outcomes for Patients with Out-of-Hospital Cardiac Arrest and Bystander CPR or a Shockable Rhythm?

2025

Prehospital emergency care

George TS, Ashburn NP, Snavely AC, Beaver BP, Chado MA +6 more

Plain English
This study looked at whether giving a single dose of epinephrine (a medication used during cardiac arrest) improves survival rates for people who experience cardiac arrest outside of a hospital, especially among those who received CPR from bystanders or had a shockable heart rhythm. Researchers found that while 19.2% of the patients had shockable rhythms and 38.9% received bystander CPR, a single dose of epinephrine did lead to better survival rates for patients who received bystander CPR, increasing their survival chances by 61%. However, for those who did not receive bystander CPR or had different heart rhythms, the results were similar to the traditional multi-dose approach. Who this helps: This research benefits patients who suffer cardiac arrest outside the hospital, particularly those who get immediate CPR from bystanders.

Analysis of 30-day hospital readmissions and related risk factors for COVID-19 patients with myocarditis hospitalized in the United States during 2020.

2025

Proceedings (Baylor University. Medical Center)

Patel K, Majeed H, Gajjar R, Cannon H, Bobba A +4 more

Plain English
This study examined the rates of hospital readmissions within 30 days for COVID-19 patients who also had myocarditis in the U.S. during 2020. It found that 11.7% of these patients were readmitted, with the main factor contributing to higher readmission rates being patients who left the hospital against medical advice. The study highlights the need for better discharge planning and follow-up care for these patients to improve their outcomes. Who this helps: This helps patients with COVID-19 and myocarditis, as well as their healthcare providers.

Endovascular Therapy in Mild Ischemic Strokes Presenting Under 6 hours: An International Survey.

2020

Journal of stroke and cerebrovascular diseases : the official journal of National Stroke Association

Krementz NA, Landman A, Gardener HE, Arauz A, Rodriguez AD +11 more

Plain English
This study looked at how doctors around the world decide to use endovascular therapy (EVT) for patients with mild ischemic strokes, specifically when symptoms appear within six hours. Researchers surveyed 492 doctors and found that EVT was offered to 48% of mild stroke cases they considered, mostly to patients with certain types of blockages in their blood vessels. The study shows that there are significant differences in how EVT is used across countries, highlighting the need for more consistent treatment guidelines for such strokes. Who this helps: This helps patients who suffer from mild ischemic strokes and their doctors.

Hereditary hemochromatosis: patient experiences of the disease and phlebotomy treatment.

2011

Transfusion

Brissot P, Ball S, Rofail D, Cannon H, Jin VW

Plain English
This study looked at how patients with hereditary hemochromatosis (HH) experience their condition and the treatment they receive called phlebotomy, which involves removing blood to reduce excess iron. Out of 210 patients surveyed, 60% reported feeling fatigued and 50% had joint pain, while many found the treatment beneficial despite over half experiencing side effects. This is important because people often get diagnosed late, and better awareness and treatment options could improve their quality of life. Who this helps: This benefits patients with hereditary hemochromatosis and their doctors.

Glass B, Cannon H, Branson M, Hanagud S, Paulsen G

Plain English
The DAME project focused on improving drilling technology for exploring Mars by testing a new drill system in challenging conditions in the Arctic. Researchers found that the drill could adapt to problems while drilling and help recover from unexpected issues, making it more reliable for use on Mars. This matters because it enhances our ability to gather information from other planets, which is crucial for future exploration. Who this helps: This benefits scientists and engineers involved in space exploration.

Astrobiology

Prieto-Ballesteros O, Martínez-Frías J, Schutt J, Sutter B, Heldmann JL +5 more

Plain English
Researchers conducted a month-long simulated Mars drilling mission in Spain's Río Tinto to test new drilling and sampling technologies that could be used on Mars. They successfully drilled down 606 centimeters but only recovered 35% of the core material due to the challenging conditions. The findings demonstrate that even in tough environments, useful geological and possibly biological samples can be collected, which is crucial for future Mars exploration. Who this helps: This helps scientists and engineers involved in Mars exploration missions.

Patients' knowledge and experience of adjuvant endocrine therapy for early breast cancer: a European study.

2007

Breast (Edinburgh, Scotland)

Wengström Y, Aapro M, Leto di Priolo S, Cannon H, Georgiou V

Plain English
The study looked at how much post-menopausal women with early breast cancer know about and are involved in their adjuvant endocrine therapy, a treatment to lower the risk of cancer returning. Out of 547 women from nine European countries, 41% were not involved in deciding to start this therapy, and only 57% received information about possible side effects. This is important because it shows that many women lack the knowledge and involvement they need to make informed decisions about their health. Who this helps: This helps patients with early breast cancer.

Vaccine

Bottasso O, Merlin V, Cannon L, Cannon H, Ingledew N +4 more

Plain English
This study looked at 670 adults who lived or worked with leprosy patients in Argentina to see how effective different vaccinations were in boosting their immune responses. Researchers found that all three types of vaccines used increased immune reactions significantly, with the BCG vaccine alone showing the strongest effects. This is important because it suggests that a vaccine containing M. vaccae could be a useful option for protecting people at risk for leprosy, benefiting future vaccinations without complicated preparation. Who this helps: Patients at risk of leprosy and healthcare providers involved in their care.

Journal of clinical microbiology

Irwin GR, Allen AM, Segal HE, Willhight M, Cannon H +1 more

Plain English
This study looked at military personnel who had antibodies to the hepatitis B virus to see how long those antibodies would remain after one year. Initially, 64% showed strong reactions to the virus, but after a year, 87% of those who reacted to both virus types still had antibodies, while only 41% and 16% of those who reacted to only one type retained antibodies. These findings matter because they help understand how long protection against hepatitis B lasts, especially for people who may have been exposed to the virus. Who this helps: This helps military personnel and healthcare providers managing hepatitis B exposure.
