What does HARRISON TUTTLE research?

Dr. Tuttle studies how to better treat patients with atrial fibrillation (an irregular heartbeat), childhood obesity, and advanced cancers like urothelial and non-small cell lung cancer. In his research, he looks for ways to improve treatment protocols to minimize hospitalizations for atrial fibrillation while evaluating effective treatments for overweight children in low-income communities. He also investigates the effectiveness of drug combinations for various cancers, aiming to find therapies that increase survival rates and improve health outcomes for patients.

Key findings

  • In a study of 935 patients with primary atrial fibrillation or flutter, 21.5% presented to the emergency department, with 93.6% reporting mild to moderate symptoms. Despite stability, nearly 66% were admitted, indicating a need for improved treatment protocols.
  • Patients at an Atrial Fibrillation Transitions of Care Clinic were more likely to receive the proper assessments compared to a control group, with 99% evaluated for stroke risk and 97% given appropriate blood thinners.
  • In a phase II trial for advanced urothelial cancer, 12 out of 28 patients receiving a combination of cetuximab and paclitaxel stayed cancer-free for 16 weeks, while the overall survival rate was approximately 42 weeks.
  • In a study focused on advanced colorectal cancer treatments, 54% of patients responded positively, with those not receiving bevacizumab having a median survival of 42.5 months, compared to 18 months for those who did.
  • In treating advanced non-small cell lung cancer, 57% of patients responded to a new therapeutic combination, and the average survival time after initiation of treatment was 13.8 months.

Childhood obesity (Print)

Jelalian E, Evans W, Darling KE, Seifer R, Vivier P +8 more

Plain English
This study focused on improving a childhood obesity program for low-income families in Rhode Island. Researchers adapted an existing weight management program to make it suitable for diverse families and tested it over 10 months with children aged 6 to 12 who are overweight. Early results will assess how well the program works and how accepted it is by participants, which is important for creating effective and accessible solutions to childhood obesity. Who this helps: This benefits children and families in low-income communities struggling with obesity.

Sadaf MI, O'Bryan J, Biese K, Chen S, Deyo Z +5 more

Plain English
This study looked at patients who visited the emergency department for atrial fibrillation (AF) or atrial flutter (AFL), focusing on their characteristics and treatment. Out of 935 patients, 202 (21.5%) had primary AF/AFL, and most of them (93.6%) reported mild to moderate symptoms. Even though they were generally stable, nearly two-thirds of these patients were still admitted to the hospital, highlighting a need for better protocols to avoid unnecessary hospitalizations. Who this helps: This benefits patients with AF/AFL and healthcare providers by potentially reducing unnecessary admissions.

JACC. Clinical electrophysiology

Abadie BQ, Hansen B, Walker J, Deyo Z, Biese K +5 more

Plain English
This study looked at whether a special clinic for people with atrial fibrillation (AF) could improve the quality of care they receive. It found that patients treated at this specialized clinic were much more likely to get the right assessments and treatments, such as having their stroke risk evaluated (99% vs. 26%) and receiving appropriate blood thinners (97% vs. 88%). This matters because better care can lead to fewer complications and hospitalizations for patients with AF. Who this helps: Patients with atrial fibrillation.

Abadie BQ, Hansen B, Walker J, Deyo Z, Biese K +6 more

Plain English
This study looked at patients who went to the emergency room with a type of irregular heartbeat called atrial fibrillation (AF) and assessed how many would return to a normal heartbeat on their own without needing immediate treatment. It found that 63% of patients converted to a normal rhythm within about 2.3 days, and 83% did so within 30 days. Only 6.3% eventually needed electrical cardioversion after 90 days, suggesting that many patients can be treated effectively with a follow-up plan instead of aggressive treatments in the emergency room. Who this helps: This helps patients with atrial fibrillation by providing a less intensive treatment option.

Plain English
This study looked at the effectiveness and safety of a combination treatment for patients with advanced colorectal cancer. It tested a group of drugs, including capecitabine and oxaliplatin, with or without the addition of bevacizumab. The results showed that while 54% of patients had positive responses, those who received the treatment without bevacizumab had better outcomes — they had a median survival of 42.5 months compared to 18 months for those who received both drugs. This research is important because it highlights potential risks in combining these treatments. Who this helps: This helps oncologists and colorectal cancer patients by providing insights into more effective treatment options.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology

Wong YN, Litwin S, Vaughn D, Cohen S, Plimack ER +6 more

Plain English
This study looked at how effective the drug cetuximab is, either alone or combined with paclitaxel, in treating patients with advanced urothelial carcinoma who had already received one round of chemotherapy. They found that when given alone, cetuximab didn’t work well, as nine out of the first eleven patients showed disease progression within eight weeks. However, in the group receiving both drugs, 12 out of 28 patients were still cancer-free after 16 weeks, and the overall survival rate was about 42 weeks, indicating that the combination therapy might be more beneficial. Who this helps: This helps patients with advanced urothelial cancer seeking better treatment options.

Journal of thoracic oncology : official publication of the International Association for the Study of Lung Cancer

Huang CH, Millenson MM, Sherman EJ, Borghaei H, Mintzer DM +7 more

Plain English
This study looked at how well a combination of two chemotherapy drugs, docetaxel and gemcitabine, works for patients with recurrent non-small cell lung cancer after they have already tried other treatments. Out of 35 patients, 23% responded to the treatment, with an average event-free period of 5.7 months and overall survival of 12.5 months. It matters because these results indicate a possible effective option for patients who have limited treatment choices after their initial therapies. Who this helps: This helps patients with recurrent non-small cell lung cancer and their doctors looking for better treatment options.

Plain English
This study looked at a new treatment combination of cetuximab, carboplatin, and paclitaxel for patients with advanced non-small cell lung cancer (NSCLC) who had not received chemotherapy before. Out of 53 participants, 57% responded to the treatment, with some patients experiencing complete or partial tumor shrinkage. On average, patients lived for about 13.8 months after starting the treatment, and about 19% didn't see their cancer get worse within a year. Who this helps: This benefits patients with advanced non-small cell lung cancer seeking effective first-line treatment options.

Alcohol and alcoholism (Oxford, Oxfordshire)

Chen Y, Mendoza S, Davis-Gorman G, Cohen Z, Gonzales R +3 more

Plain English
This study examined how neutrophils, a type of immune cell, respond to a virus that causes AIDS in mice and how this response changes when the mice also consume alcohol over time. Researchers found that after one month, neutrophils experienced an increase in certain activity markers, but by two months, those markers decreased, although they rose again at three months in the AIDS group. In the group consuming alcohol, different patterns were seen in the neutrophil markers, suggesting that both the virus and alcohol change how these immune cells function. Who this helps: This research benefits doctors and researchers studying the effects of viral infections and alcohol on the immune system.
