RECRUITING

Probiotic Intervention Study

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The current standard of care for obesity is the optimal management of comorbid conditions such as diabetes and hyperlipidemia, and counseling on diet, weight loss, or increased physical activity programs. However, lifestyle, diet, and behavioral interventions may provide between 7-10% reduction in initial weight and even fewer with long-term weight loss. In severely obese patients (BMI\>40 or BMI\>35 with comorbidities), bariatric surgery is also a potential treatment, but there is a high barrier for patients to undergo surgery for weight loss. These barriers include an aversion to major abdominal surgery, long recovery time, potential risk of vitamin deficiency, and risk for abdominal pain. For these reasons, there is a paramount need for other treatments for obesity and for food addiction. The current standard of care for obesity and food addiction is difficult to implement and lacks sustained efficacy. Most struggle to complete treatment, lose minimal weight, lack sustained weight loss, and engage in the well-known "YoYo" diet phenomenon. While bariatric surgery is currently the only effective treatment for obesity, there are several barriers associated with it such as eligibility requirements, invasiveness, difficult recovery, and cost making it not readily available for everyone. Some approved medications that help with obesity, such as orlistat, lorcaserin, or naltrexone-bupropion, have not been widely adopted by providers or patients due to their limited responses and adverse side effects. Probiotic cocktails have shown to be safe with little to no side effects. Preclinical models of probiotics demonstrate the ability to curb obesity in animal models. Therefore, a probiotic that is able to show significant weight loss along with lifestyle modifications would be highly adopted and desirable.

  17. * Heavy use of alcohol and drugs will be determined by a positive endorsement on the MINI+. If the MINI+ is positive for alcohol or drug dependence or abuse, the participant will be excluded. In regards to tobacco use, participants will be excluded if they smoke more than 1/2 pack per day.
  18. * Cannabis use will not be exclusionary. If the MINI+ is positive for drug dependence or abuse, the participant will be excluded.
  19. * Significant change in usual diet and/or weight loss of more than 10lbs in the last 2 months.
  20. * Anyone taking medicines on the medication exclusion list.
  21. * Non-English Speakers (due to the use of validated questionnaires and limited availability of translated copies, participants must be fluent in English so that they will be able to read and follow directions easily.
  22. * Maintenance pharmacotherapies will not be exclusionary so long as they have been on a stable dose for 6months.
  23. * Body weight at enrollment greater than 400lbs.
  24. * Exclude from Optional MRI if: participant is unable to safely participate in the MRI (claustrophobia, presence of devices affected by MRI such as pacemakers, neurostimulators, metallic foreign bodies, etc.).
