The North Karelia Project: Prevention of Cardiovascular Disease in Finland Through Population-Based Lifestyle Interventions

The North Karelia Project was started in 1972 as a response to the high cardiovascular mortality among men in North Karelia, Finland's easternmost province. Prevalent cardiovascular disease risk factors in the province included elevated serum cholesterol, hypertension, and smoking. Through a sociobehavioral framework utilizing community-based interventions and national-level policy changes and legislation, the project targeted lifestyle changes as a means to alleviate cardiovascular disease risk factors. Diet recommendations included minimizing the use of saturated fats and decreasing salt intake. Another target of the project was to reduce the prevalence of smoking. As a result of the lifestyle interventions that continued beyond the initial 5 years of the project and then expanded to all of Finland, there were significant reductions in serum cholesterol levels, hypertension, smoking prevalence, and cardiovascular disease mortality. The North Karelia Project demonstrates that successful population-based lifestyle interventions serve as a sustainable public health solution to the growing chronic disease burden.

Positive Psychology and Hope as Lifestyle Medicine Modalities in the Therapeutic Encounter: A Narrative Review

The majority of deaths in the United States are attributable to lifestyle-associated chronic diseases. Therapeutic encounters must now routinely address lifestyle-related behavior changes and promote patients' active involvement in self-care and chronic disease management. Positive psychology has been recognized in the realm of lifestyle medicine for its potential applications in effecting patient behavior change. One notable framework within positive psychology that is well suited for facilitating specific behavior changes is hope theory, which can be used to elicit change talk and build agency among patients with chronic diseases. This review explores key literature in positive psychology and hope theory and its practical applications to direct patient care, which includes an illustrative case study. There are still many unexplored intersections of health-related variables and hope. The cognitive framework of hope theory lends itself well to a broad range of situations, including brief ambulatory encounters. Clinicians will be instrumental in increasing our understanding of how hope theory can be applied to the therapeutic encounter. There are simple and efficient ways to innovate in this area. Having information about a patient's hope has the potential to make empathic connections easier and create opportunities to ask specific questions to help patients overcome barriers.

Community-Engaged Lifestyle Medicine: Building Health Equity Through Preventive Medicine Residency Training

Vulnerable populations in the U.S. experience persistent disparities in chronic disease and associated lifestyle-based risk factors. Because of environmental, cultural, and health systems barriers affecting vulnerable populations, lifestyle medicine interventions may miss those at highest risk for chronic disease. Numerous reports suggest that graduate medical education (GME) inadequately prepares physicians to promote healthy lifestyles and health equity in vulnerable groups. General Preventive Medicine/Public Health (GPM/PH), the medical specialty dedicated to health promotion and disease prevention in populations, can fill this gap. However, virtually no published reports describe health equity-oriented GPM/PH residency programs. The authors describe implementation of the novel Community-Engaged Lifestyle Medicine at the University of Texas Rio Grande Valley GPM/PH residency program between 2017 and 2018. Community-Engaged Lifestyle Medicine applies community engagement principles to lifestyle medicine practice, training residents in multilevel, intersectoral approaches promoting behavior change and health equity. Community-Engaged Lifestyle Medicine is described in the context of health equity and the local border community, along with associated curricular objectives and experiences. In 2017, the authors assessed first-year Community-Engaged Lifestyle Medicine process outcomes, fidelity to health equity mechanisms, and feasibility in a GPM/PH residency, by mapping Community-Engaged Lifestyle Medicine activities to American Council of Graduate Medical Education and the American College of Lifestyle Medicine competencies. The Community-Engaged Lifestyle Medicine framework was successfully implemented in 2017, meets all American Council of Graduate Medical Education competency domains, and demonstrates fidelity to mechanisms of community engagement, health equity, and the practice of lifestyle medicine. Community-Engaged Lifestyle Medicine represents a feasible and valid framework to promote health equity via GPM/PH and GME training and practice.

Mechanisms of Sex Disparities in Cardiovascular Function and Remodeling

Epidemiological studies demonstrate disparities between men and women in cardiovascular disease prevalence, clinical symptoms, treatments, and outcomes. Enrollment of women in clinical trials is lower than men, and experimental studies investigating molecular mechanisms and efficacy of certain therapeutics in cardiovascular disease have been primarily conducted in male animals. These practices bias data interpretation and limit the implication of research findings in female clinical populations. This review will focus on the biological origins of sex differences in cardiovascular physiology, health, and disease, with an emphasis on the sex hormones, estrogen and testosterone. First, we will briefly discuss epidemiological evidence of sex disparities in cardiovascular disease prevalence and clinical manifestation. Second, we will describe studies suggesting sexual dimorphism in normal cardiovascular function from fetal life to older age. Third, we will summarize and critically discuss the current literature regarding the molecular mechanisms underlying the effects of estrogens and androgens on cardiac and vascular physiology and the contribution of these hormones to sex differences in cardiovascular disease. Fourth, we will present cardiovascular disease risk factors that are positively associated with the female sex, and thus, contributing to increased cardiovascular risk in women. We conclude that inclusion of both men and women in the investigation of the role of estrogens and androgens in cardiovascular physiology will advance our understanding of the mechanisms underlying sex differences in cardiovascular disease. In addition, investigating the role of sex-specific factors in the development of cardiovascular disease will reduce sex and gender disparities in the treatment and diagnosis of cardiovascular disease. © 2019 American Physiological Society.

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.

Two Cases Comparing the Presentations and Outcomes of Heroin-induced Toxic Leukoencephalopathy

Heroin-induced toxic leukoencephalopathy (TLE) is an uncommon condition that presents with nonspecific and variable neuropsychiatric findings. It may result in satisfactory recovery or death. Traditionally referred to as "chasing the dragon" syndrome and associated with inhalation of pyrolyzed heroin, recent publications have reported forms of the syndrome associated with noninhaled heroin. We report 2 cases of heroin-induced TLE associated with noninhaled routes of administration and a well-documented history of opioid use disorder. The patient in the first case presented with moderate to severe symptoms. Magnetic resonance imaging of the brain revealed increased T2 and fluid-attenuated inversion recovery signals bilaterally throughout subcortical and periventricular white matter. She survived with significant cognitive issues at discharge from which she adequately recovered by 11-month follow up. The patient in the second case presented with severe symptoms. Magnetic resonance imaging of the brain showed diffuse abnormal increased T2 and fluid-attenuated inversion recovery signals in the white matter of the centrum semiovale and corona radiata. The patient died within 3 weeks of presentation. Both cases illustrate the underrecognition of the form of TLE associated with noninhaled heroin and the difficulties involved in confirming recent heroin use that likely delayed the diagnosis. Further, noninhaled heroin-induced TLE can present with specific signs and symptoms that may help clinicians delineate it from the inhaled form. Given the ongoing opioid epidemic, early and accurate recognition of this condition is of paramount importance.

Management Challenges of Recurrent Foreign Body Ingestions in a Psychiatric Patient: A Case Report

Intentional foreign body ingestions (FBIs) are commonly seen in adult patients with intellectual disabilities, substance use, severe psychiatric conditions, or external motivations, but these cases are rarely reported in the psychiatric literature. We present the case of a patient with an extensive history of FBIs and suicide attempts and a multitude of psychiatric diagnoses including borderline personality disorder, major depressive disorder, posttraumatic stress disorder from significant abuse in foster care, obsessive-compulsive disorder, and pica. During the single hospitalization described in this report, she had multiple incidents of self-harm, aggression, and 9 FBIs. A multidisciplinary team involving psychiatry, emergency medicine, gastroenterology, surgery, internal medicine, nursing, social work, behavioral health technicians, case management, chaplain, the legal department, police officers, and hospital maintenance was necessary for care coordination. Interventions included 8 endoscopies and an abdominal surgery to retrieve swallowed foreign bodies, pain management, psychopharmacological and psychotherapeutic interventions for agitation, and environmental precautions to minimize the risk of ingestion. Ultimately, to prevent further trauma and limit additional opportunities for FBI, a collaborative decision was made with the patient to discharge her to her home with outpatient psychologist and psychiatrist support. This case describes the complexities of hospital management of a patient with intentional recurrent FBI, highlighting the importance of a critical assessment of risk versus benefit for prolonging hospitalization. Development of practical management protocols and risk assessments for continued hospitalization is necessary for patients with recurrent intentional FBIs.

Abstract 030: Low-dose Aspirin During Pregnancy Does Not Prevent Augmentation of Arterial Contractions to Thromboxane A 2 in a Rat Model of Pregnancy-Induced Hypertension

Background: Daily intake of low dose aspirin after 12 weeks of gestation is currently recommended as a preventative intervention in pregnancies at high risk of developing preeclampsia. We previously showed that treating pregnant rats with a synthetic ligand of Toll-like receptor 9 (TLR9; ODN2395) activated the innate immune system causing preeclampsia-like characteristics such as maternal hypertension, vascular oxidative stress, and augmented vascular responses to thromboxane A 2 (TxA 2 ).

Hypothesis: Low-dose aspirin treatment would ameliorate ODN2395-induced augmented responses to TxA 2 in maternal arteries.

Methods: Pregnant rats were treated with ODN2395 (300 μg) or vehicle on gestational day (GD) 14, 16, 18. Daily low-dose aspirin treatment (1.5 mg/kgBW) started on GD10 and continued throughout gestation. Systolic blood pressure was measured using the tail-cuff method on GD19. On GD21, uterine (UTA) and mesenteric resistance artery (MES) responses to a TxA 2 mimetic (U46619, 10 -9 -10 -6 M) was measured with a wire myograph.

Results: Uterine arteries from the ODN2395+Aspirin-treated group had greater contractile responses to U46619 compared to all other groups [Emax, %KCl: Control (n=6): 109.2±8.8; ODN2395 (n=5): 124.4±20.2; Aspirin (n=5): 76.08±11.2; ODN2395+Aspirin (n=5): 134.7±4.5, p<0.05]. Aspirin alone reduced MES responses to U46619 compared to control and MES from ODN2395 and ODN2395+Aspirin groups had greater contractile responses to U46619 compared to Aspirin alone [Emax, %KCl: Control (n=8): 109.8±5.2; ODN2395 (n=6): 111.1±4.3; Aspirin (n=7): 89.4±3.6; ODN2395+Aspirin (n=8): 121.7±6.3, p<0.05]. Rats treated with ODN2395 and ODN+Aspirin had greater systolic blood pressure compared to control rats [control (n=8): 97.3±3.2 mmHg, ODN2395 (n=6): 121.3±4.3 mmHg, Aspirin (n=8): 100.3±2.9 mmHg, ODN2395+Aspirin (n=7): 127.5 ±6.7 mmHg, p<0.05].

Conclusion: Exposure to a TLR9 agonist during pregnancy resulted in augmented contractile responses to a TxA 2 mimetic in maternal arteries when rats were in a regime of low-dose aspirin. This was shown in arteries from both reproductive and non-reproductive vascular beds.
