Setting Patient-Centered Priorities for Cardiovascular Disease in Central Appalachia: Engaging Stakeholder Experts to Develop a Research Agenda.

The disproportionate burden of cardiovascular diseases (CVD) and associated risk factors continues to exist in the Central Appalachian Region (CAR) of the United States. Previous studies to gather data about patient-centered care for CVD in the region were conducted through focus group discussions. There have not been any studies that used a collaborative framework where patients, providers, and community stakeholders were engaged as panelists. The objective of this study was to identify patient-centered research priorities for CVD in the CAR. We used a modified Delphi approach to administer questionnaires to forty-two stakeholder experts in six states representing the CAR between the fall of 2018 and the summer of 2019. Their responses were analyzed for rankings and derived priorities by research gaps. Six of the fifteen research priorities identified were patient-centered. These patient-centered priorities included shorter wait times for appointments; educating patients at their level; empowering patients to take responsibility for their health; access to quality providers; heart disease specialists for rural areas; and lifestyle changes. The participants' commitments to identify patient-centered research priorities indicate the potential to engage in community-based collaboration to address the burden of CVD in the CAR.

Lifestyle Medicine and Economics: A Proposal for Research Priorities Informed by a Case Series of Disease Reversal.

Chronic disease places an enormous economic burden on both individuals and the healthcare system, and existing fee-for-service models of healthcare prioritize symptom management, medications, and procedures over treating the root causes of disease through changing health behaviors. Value-based care is gaining traction, and there is a need for value-based care models that achieve the quadruple aim of (1) improved population health, (2) enhanced patient experience, (3) reduced healthcare costs, and (4) improved work life and decreased burnout of healthcare providers. Lifestyle medicine (LM) has the potential to achieve these four aims, including promoting health and wellness and reducing healthcare costs; however, the economic outcomes of LM approaches need to be better quantified in research. This paper demonstrates proof of concept by detailing four cases that utilized an intensive, therapeutic lifestyle intervention change (ITLC) to dramatically reverse disease and reduce healthcare costs. In addition, priorities for lifestyle medicine economic research related to the components of quadruple aim are proposed, including conducting rigorously designed research studies to adequately measure the effects of ITLC interventions, modeling the potential economic cost savings enabled by health improvements following lifestyle interventions as compared to usual disease progression and management, and examining the effects of lifestyle medicine implementation upon different payment models.

Retrospective Evaluation of an Online Diabetes Health Coaching Program: A Pilot Study.

An estimated one third of American adults have prediabetes; over 30 million have type 2 diabetes mellitus. Health and wellness coaching is an emerging tool for preventing and treating chronic disease. Mastering Diabetes (MD) promotes a low-fat, plant-based, whole-food diet, utilizing online education, day-to-day accountability and support, and video conferencing. This pilot study provides a retrospective view of the effectiveness of MD to treat diabetes. Current and former clients of MD were invited to participate in a survey. On completion of the online consent, subjects were asked a series of questions in a REDCap-based survey: age, gender, enrollment date in MD, changes in weight, HbA1c, medication use, overall health, and current level of adherence to achieved changes. Overall, 253 (8.9%) participants responded to the survey; 80.6% were females, mean age was 56 years. Most of those responding (78.4%, P < .001) reported weight loss; 68.8% (P < .001) reported decreased HbA1c; 52.4% reported decreased medication use; 86.8% reported continued health improvement since having participated in MD; and 83.5% found the online program very helpful. This study demonstrated improvement in HbA1c and weight in participants in an online health and wellness coaching. Study limitations prevent drawing generalizable conclusions; further prospective evaluation is needed.

Sticking to the Problem: Engineering Adhesion in Molecular Endoscopic Imaging.

Cancers of the digestive tract cause nearly one quarter of the cancer deaths worldwide, and nearly half of these are due to cancers of the esophagus and colon. Early detection of cancer significantly increases the rate of survival, and thus it is critical that cancer within these organs is detected early. In this regard, endoscopy is routinely used to screen for transforming/cancerous (i.e. dysplastic to fully cancerous) tissue. Numerous studies have revealed that the biochemistry of the luminal surface of such tissue within the colon and esophagus becomes altered throughout disease progression. Molecular endoscopic imaging (MEI), an emerging technology, seeks to exploit these changes for the early detection of cancer. The general approach for MEI is as follows: the luminal surface of an organ is exposed to molecular ligands, or particulate probes bearing a ligand, cognate to biochemistry unique to pre-cancerous/cancerous tissue. After a wash, the tissue is imaged to determine the presence of the probes. Detection of the probes post-washing suggests pathologic tissue. In the current review we provide a succinct, but extensive, review of ligands and target moieties that could be, or are currently being investigated, as possible cognate chemistries for MEI. This is followed by a review of the biophysics that determines, in large part, the success of a particular MEI design. The work draws an analogy between MEI and the well-advanced field of cell adhesion and provides a road map for engineering MEI to achieve assays that yield highly selective recognition of transforming/cancerous tissue in situ.

Lifestyle Medicine: Successful Reimbursement Methods and Practice Models.

Preventable and reversible chronic diseases affect millions of Americans, costing the United States billions of dollars annually for treatments that slow the trajectory but fail to address the root cause of illness. Lifestyle medicine is efficacious, and research has shown that this medical approach garners a significant return on investment in the treatment of many chronic diseases. To obtain an overview of successful reimbursement and practice models used by practitioners, American College of Lifestyle Medicine members were invited to participate in an online survey regarding their experience with lifestyle medicine services and reimbursement models. Three hundred and fifty-one respondents with diverse practice structures, geographical locations, and educational backgrounds completed the survey. The results demonstrate that practitioners are utilizing a variety of lifestyle medicine programs and reimbursement and practice models. Seventy-four percent of respondents are currently providing lifestyle medicine, though the majority do not receive reimbursement for their services. This study provides examples of successful lifestyle medicine reimbursement and practice models, as well as demonstrates the need for continued advocacy for sustainable reimbursement of lifestyle medicine services.

Body Mass Index Change as a Predictor of Biometric Changes following an Intensive Lifestyle Modification Program.

The initial benefits of lifestyle modification programs such as reduction in chronic and cardiovascular diseases (CVD) risk factors have been well documented. However, such positive effects may deteriorate over time following relapse into inactivity. Timely detection of weight regain leading to the deterioration of the accrued benefits could trigger early resumption of intensive lifestyle intervention. To date, no known cost-effective, noninvasive approach for monitoring long-term outcomes has yet been established. The purpose of this study was to determine if body mass index (BMI) change predicted changes in other CVD biometric markers during an intensive lifestyle modification program. This study was an observational, retrospective review of records of participants from the Complete Health Improvement Program (CHIP). Biomarker changes of participants in this community-based Intensive Therapeutic Lifestyle Modification Program (ITLMP) offered in Athens, Ohio, a rural Appalachian college town, between April 2011 and June 2017 were reviewed retrospectively. BMI, heart rate (Pulse), systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting blood levels of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), and glucose (FBS) were monitored before and after program completion. Data were analyzed using a multivariate general linear model. The sample analyzed consisted of 620 participants (mean age of 52.3±13.0 years, 74.5% female). Controlling for age and gender, BMI change significantly predicted 5 out of the 8 biomarker changes measured [Wilk's λ = 0.939, F(8,526) = 4.29, p <.0001]. Specifically, a 1-point BMI decrease was associated with 4.4 units decrease in TC, 3.2 units in LDL, 5.3 units in TG, 2 units in SBP, and 1 unit in DBP (all p values < .05). These results suggest that change in BMI may be a useful predictor of change in other CVD biomarkers' outcomes during and after an ITLMP participation. Tracking BMI, therefore, could serve as a proxy measure for identifying regressing biomarker changes following participation in an ITLMP leading to a timelier reassessment and intervention. Future studies evaluating the value of BMI as a surrogate for highlighting overall cardiovascular health are warranted.

Effect of Participation with Accompanying Household Member in the Complete Health Improvement Program in Appalachia.

Intensive therapeutic lifestyle modification programs, such as the Complete Health Improvement Program (CHIP), reduce cardiovascular disease (CVD) risk factors. However, there are little data on how participation in CHIP with a household member can affect CVD biomarkers. This study focuses on the benefit of joint participation of household members in CHIP in order to have a better outcome in improving CVD risk factors compared with lone or individual participation. Data from 20 CHIP classes offered from 2011 to 2015 in Athens, Ohio, where each class was conducted over 2-4 months, consisting of 16-18 sessions, were collected. Body mass index (BMI), blood pressure, fasting glucose, and lipid profiles were measured before and near the completion of each class. A statistically significant greater reduction in BMI (p = 0.003) in those who attended with a household member compared to those who attended as individuals was found. CHIP has some effect on various CVD risk factors for those who attend intensive therapeutic lifestyle modification programs with an accompanying household member. Hence, encouragement of participation with a family member or a "buddy" may be prudent, especially if weight reduction is a key program participation goal. Further evaluation of the "buddy effect" involving both of those residing in the same household and those who do not but nevertheless provide mutual support is warranted.

An adhesion based approach for the detection of esophageal cancer.

Esophageal cancer has a 5 year survival rate of ∼20%. This dismal prognosis is due, in part, to the fact that esophageal cancer often presents at a late stage. Thus, there is a critical need for assays that enable the early detection of cancerous tissue within the esophagus. The luminal surface of the esophagus expresses signature molecule(s) at sites of transformation providing an avenue for the development of in situ assays that detect neoplastic growth within the esophagus. An attractive approach, receiving increased attention, is the endoscopic administration of particles conjugated with ligands to signature molecules present on transforming tissue. Detection of the particles within the esophagus, post-washing, would indicate the presence of the signature molecule and thus transforming tissue. In this work, we utilized cancerous and normal esophageal cells to provide in vitro proof of principle for this approach utilizing ligand-conjugated microspheres and demonstrate the need, and provide the framework for, engineering this technology. Specifically, the study (i) reveals selective increased expression of signature molecules on cancerous esophageal cells relative to normal cells; (ii) demonstrates selective binding of ligand-conjugated microspheres to cancerous esophageal cells relative to normal cells; (iii) demonstrates that the selective recognition of cancerous, relative to normal esophageal cells, is highly dependent on the biophysical design of the assay; and (iv) advocates utilizing the knowledge from the field of cell adhesion as a guide for the effective development of ligand-conjugated particle-based schemes that seek to detect esophageal oncogenesis in situ.

Nurturing the Seeds of Change: Strengthening the Lifestyle Medicine Movement With the Donald A. Pegg Student Leadership Award.

Student-led Lifestyle Medicine Interest Groups (LMIGs) empower the next generation of healthcare professionals to tackle the pandemic of lifestyle-related chronic diseases and provide important pathways to increasing the visibility of Lifestyle Medicine (LM) in health professions schools. Each year, the Donald A. Pegg Student Leadership Award offers four allied health students a seed grant to start or support LMIGs at their schools as well as financial assistance to attend the annual American College of Lifestyle Medicine (ACLM) conference. The 2017 student winners were Paresh Jaini, Albert Barrera, Alyssa Greenwell, and Alicja Baska. With the support of the Pegg Award, the awardees and their faculty advisors have made great strides in LM at their institutions in the areas of research, community outreach, student education, and global networking. Their LMIG activities have included students presenting research at national conferences, initiating a chapter of the national organization Walk with a Doc, hosting educational lectures on LM principles, sponsoring plant-based cooking sessions, facilitating stress management workshops, and hosting a national-level LM congress in Europe. Through the ACLM, the Pegg Award generates an atmosphere of growth for LMIGs, fostering the expansion, vision, and integration of LM into the education of health professions students worldwide.

Employer-Funded Complete Health Improvement Program: Preliminary Results of Biomarker Changes.

CONTEXT: Previous studies of the Complete Health Improvement Program (CHIP) have demonstrated short-term improvements in select metabolic and cardiovascular biomarkers in community-based programs. However, less is known about the benefits of an employer-funded lifestyle intervention program. OBJECTIVES: To determine if participation in employer-provided CHIP would result in improvements in short-term metabolic and cardiovascular biomarkers, and to compare the results of the current study to a larger national study. METHODS: This observational study evaluated metabolic and cardiovascular biomarker changes in employer health insurance beneficiaries enrolled in CHIP between August 2012 and November 2014. Body mass index; blood pressure (systolic and diastolic); total cholesterol, low-density lipoprotein, high-density lipoprotein, fasting plasma glucose, and triglyceride levels; and weight were measured at baseline and after CHIP. RESULTS: Of 160 employees enrolled in CHIP, 115 women and 45 men agreed to participate in the study. Overall, the participants demonstrated significant reductions in body mass index, from a baseline average of 31.5 to a post-CHIP average of 30.5 (P<.001), systolic blood pressure from 124.5 to 119.4 mm Hg (P=.017), diastolic blood pressure from 77.3 to 74.5 mm Hg (P=.046), total cholesterol from 186.0 to 168.8 mg/dL (P<.001), low-density lipoprotein from 112.9 to 99.3 mg/dL (P<.001), high-density lipoprotein from 48.8 to 46.4 mg/dL (P<.001), and fasting plasma glucose from 100.8 to 96.5 mg/dL (P<.001). CONCLUSION: When funded by an employer, CHIP demonstrated short-term improvements in select metabolic and cardiovascular biomarkers. Future studies will analyze these data to determine whether these findings translate into subsequent decreased employee absenteeism and reduced beneficiary health claims.

Developing an Academic Lifestyle Medicine Clinic Model.

An introduction to lifestyle medicine as a patient, has led to the development of a lifestyle medicine program, website and practice. Having the advantage of practicing in an academic setting and a part time endoscopy practice has allowed for exploration and experimentation of different models of delivery of lifestyle medicine, the goal being to provide affordable accessible lifestyle medicine in a manner that is reproducible and sustainable for medical residents and students.

Effectiveness of the Complete Health Improvement Program in Reducing Risk Factors for Cardiovascular Disease in an Appalachian Population.

CONTEXT: In 11 counties in Appalachian Ohio, the self-reported prevalence of diabetes mellitus (11.3%) is higher than the state (7.8%) or national (7.2%) average. Direct medical costs for diabetes in the United States are estimated at $176 billion annually. Indirect costs from disability, work loss, and premature death add up to another $69 billion. OBJECTIVE: To determine the effectiveness of the Complete Health Improvement Program (CHIP) in reducing cardiovascular disease (CVD) risk factors in a sample of Appalachian participants with elevated fasting blood glucose (FBG) levels or a diagnosis of type 2 diabetes mellitus (T2DM). METHODS: In a retrospective study, data from 6 CHIP cohorts conducted in Appalachian Ohio from 2011 to 2012 were combined and analyzed for short-term changes in CVD risk factors from baseline. This study focused on a subsample of the overall CHIP, whose participants had elevated FBG levels or T2DM. Statistical analysis was completed by calculating means and SDs and using paired t tests to compare differences in variables. RESULTS: After the CHIP intervention, 110 participants with baseline elevated FBG levels showed notable reductions in FBG levels, total cholesterol, low-density lipoprotein cholesterol, body mass index, and systolic blood pressure (all P values <.001). Likewise, participants in the subsample with T2DM experienced reductions in all CVD risk factors (all P values <.05). CONCLUSION: The CHIP lifestyle intervention was effective in reducing CVD risk factors in this Appalachian population with elevated FBG levels or with T2DM.

Payer source influence on effectiveness of lifestyle medicine programs.

OBJECTIVES: Many chronic diseases are responsive to interventions focused on diet and physical activity. The Complete Health Improvement Program (CHIP) is an intensive, community-based lifestyle intervention that effectively treats many chronic diseases and their risk factors. This is a pilot study examining the effect of payer source for CHIP tuition on participants' outcomes. STUDY DESIGN: Seventy-nine self-selected participants (73.4% female) attended 1 of 3 CHIP classes (classes 7-9) offered January through May 2013 in Athens, Ohio. Participants were categorized into 3 groups based on the source(s) of their tuition payment: self-pay, employer-pay, or scholarship. Chronic disease risk factors for each individual were assessed at the beginning and conclusion of the program. METHODS: Outcome variables included percent reduction between pre- and post CHIP measures in body mass index, systolic and diastolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, and fasting blood glucose. Results were compared between type of payer source (out of pocket vs employer and/or scholarship) and between each individual CHIP class attended. RESULTS: There was no statistical difference in outcomes based on payer source. Those who received funding through their employer or a scholarship experienced similar effects from a lifestyle intervention program as those who paid out of pocket. CONCLUSIONS: This study demonstrates that the benefit of CHIP for reducing chronic disease risk factors exists independent of payment source, and thus suggests its benefit may cross socioeconomic lines.

Short-term effectiveness of a lifestyle intervention program for reducing selected chronic disease risk factors in individuals living in rural appalachia: a pilot cohort study.

Most Western chronic diseases are closely tied to lifestyle behaviors, and many are preventable. Despite the well-distributed knowledge of these detrimental behaviors, effective efforts in disease prevention have been lacking. Many of these chronic diseases are related to obesity and type 2 diabetes, which have doubled in incidence during the last 35 years. The Complete Health Improvement Program (CHIP) is a community-based, comprehensive lifestyle modification approach to health that has shown success in addressing this problem. This pilot study demonstrates the effectiveness of CHIP in an underserved, rural, and vulnerable Appalachian population. Two hundred fourteen participants in CHIP collectively demonstrated significant reductions in body mass index, systolic and diastolic blood pressure, and fasting blood levels of total cholesterol, low-density lipoprotein, and glucose. If these results can be repeated in other at-risk populations, CHIP has the potential to help reduce the burden of preventable and treatable chronic diseases efficiently and cost-effectively.

Preliminary development of the Active Colonoscopy Training Model.

Formal colonoscopy training requires a significant amount of time and effort. In particular, it requires actual patients for a realistic learning experience. The quality of colonoscopy training varies, and includes didactic courses and procedures proctored by skilled surgeons. A colonoscopy training model is occasionally used as part of the training method, but the effects are minute due to both the simple and tedious training procedures. To enhance the educational effect of the colonoscopy training model, the Active Colonoscopy Training Model (ACTM) has been developed. ACTM is an interactive colonoscopy training device which can create the environment of a real colonoscopy procedure as closely as possible. It comprises a configurable rubber colon, a human torso, sensors, a display, and the control part. The ACTM provides audio and visual interaction to the trainee by monitoring important factors, such as forces caused by the distal tip and the shaft of the colonoscope and the pressure to open up the lumen and the localization of the distal tip. On the computer screen, the trainee can easily monitor the status of the colonoscopy, which includes the localization of the distal tip, maximum forces, pressure inside the colon, and surgery time. The forces between the rubber colon and the constraints inside the ACTM are measured and the real time display shows the results to the trainee. The pressure sensors will check the pressure at different parts of the colon. The real-time localized distal tip gives the colonoscopy trainee easier and more confident operation without introducing an additional device in the colonoscope. With the current need for colonoscopists and physicians, the ACTM can play an essential role resolving the problems of the current colonoscopy training model, and significantly improve the training quality of the colonoscopy.

Development of a colonoscopy add-on device for improvement of the intubation process.

A colonoscopy add-on device has been developed to reduce intubation time without modification of the current colonoscope and peripheral devices. One of the main purposes of the system is to minimize trauma caused by the distal tip of the colonoscope. The detachable sensory fixture at the end of the distal tip measures the distance between the distal tip and the colon wall in three directions, and the actuation system attached at the base of the colonoscope controls the distal tip by rotating two dial knobs. The device controls the distal tip to minimize contact between the distal tip and the colon wall, and the distal tip ideally points out the next possible lumen. A compatibility test of the infrared sensory system was carried out, and the design of the actuation system was accomplished. The system is integrated and controlled by a microprocessor. The device was tested in a silicon colon and porcine intestine. The results showed that a colonoscopist successfully reached the cecum with the aid of the colonoscopy add-on device without significant contact between the colon wall and the distal tip. The colonoscopy aid device was very helpful for the novice colonoscopist.
