RESUMO
OBJECTIVE: Semaglutide, a glucagon-like peptide-1 receptor agonist is approved for weight loss and diabetes treatment, but limited literature exists regarding semaglutide use in patients with advanced chronic kidney disease (CKD). Therefore, this project assessed the safety and efficacy of semaglutide among patients with estimated glomerular filtration rate (eGFR) 15-29 mL/min/1.73 m2 (CKD stage 4), eGFR<15 mL/min/1.73 m2 (CKD stage 5) or on dialysis. METHODS: This is a retrospective electronic medical record based analysis of consecutive patients with advanced CKD (defined as CKD 4 or greater) who were started on semaglutide (injectable or oral). Data was collected between January 2018 and January 2023. Investigators verified CKD diagnosis and manually extracted data. Data were analyzed using Fisher's exact test, paired t test, linear mixed effects models and Wilcoxon signed rank test. RESULTS: Seventy-six patients with CKD 4 or greater who initiated semaglutide were included. Most patients had a history of type 2 diabetes mellitus (96.0%), and most were males (53.9%). The mean age was 66.8 y (SD 11.5) with the mean body mass index was 36.2 (SD 7.5). The initial doses were 3 mg orally and 0.25 mg by injection. Maximum prescribed dose was 1 mg (injectable) in 28 (45.2%) patients and 14 mg (orally) in 2 (14.2%) patients. Patients received semaglutide for a median duration of 17.4 (IQR 0.43, 48.8) months. Forty-eight (63.1%) patients reported no adverse effects associated with the therapy. Mean weight decreased from 106.2 (SD 24.2) to 101.3 (SD 27.3) kg (P < .001). Eight patients (16%) with type 2 diabetes mellitus T2DM discontinued insulin after starting semaglutide. Mean hemoglobin A1c (HbA1c) decreased from 8.0% (SD 1.7) to 7.1% (SD 1.3) (P < .001). Adverse effects were the primary reason for semaglutide discontinuation (37.0%), with nausea, vomiting, and abdominal pain being the most common complaints. CONCLUSIONS: Based on this retrospective study semaglutide appears to be tolerated by most individuals with CKD 4 or greater despite associated gastrointestinal side effects similar to those observed in patients with better kidney function and leads to an improvement of glycemic control and insulin discontinuation in patients with T2DM. Modest weight loss (approximately 4.6% of the total body weight) was observed on the prescribed doses. Larger prospective randomized studies are needed to comprehensively assess the risks and benefits of semaglutide in patients with CKD 4 or greater and obesity.
RESUMO
BACKGROUND: After settling in the United States (US), immigrants often accumulate obesity and cardiovascular risk factors. As mood is often associated with health behaviors in the US population, mood may be an important mediating factor in immigrant populations. METHODS: The Healthy Immigrant Community (HIC) study, set in southeast Minnesota, enrolled 475 adult participants in a weight loss intervention designed to reduce cardiovascular risk. Baseline questionnaires assessed mood, nutrition, physical activity, self-efficacy for healthy eating and physical activity, social support, and cohesion. A single-item mood rating of poor or fair was considered "negative", while ratings of good, very good, or excellent were considered "positive". RESULTS: Hispanic/Latino (n = 268) and Somali (n = 181) adults enrolled in HIC completed baseline measures and were included in this analysis. Participants endorsing negative mood compared to positive mood had lower healthy eating scores (p = 0.02), lower physical activity levels (p = 0.03), lower confidence in eating a healthy diet (p = 0.001), and felt less of a sense of belonging to their community (p = 0.01). Those endorsing negative mood reported receiving less social support to eat healthy (p = < 0.001) and be physically active (p = 0.01). They also accessed community resources for healthy eating (p = 0.001) and physical activity (p = < 0.01) less frequently than participants endorsing positive mood. CONCLUSIONS: On self-report, negative mood was associated with less healthy nutrition, lower confidence in eating healthy, sedentary lifestyle, and perceived lack of belonging to the community. Integrating mood management and self-efficacy strategies may enhance the effectiveness of lifestyle interventions to reduce obesity and cardiovascular risk among immigrants who report negative mood.

OBJECTIVE: Examine the impact of a participatory wellness continuing medical education (CME) program on physician burnout, wellness, and well-being. METHODS: Physicians attending a three-day wellness CME program. Self-reported questionnaires at baseline with paired analyses at 26-week follow-up. RESULTS: Compared to baseline, at 26 weeks there were decreases in burnout (P < .001, ES -0.68), red meat consumption (P = .02, ES -0.29), and current stress levels (P < .001, ES -0.50). There were increases in fruit/vegetable consumption (P < .001, ES 0.55), energy levels at work (P < .001, ES 0.60) and at home (P < .001, ES 0.66), quality of life (P < .001, ES 0.53), and confidence (P < .001, ES 0.89) and frequency (P = .01, ES 0.32) of counseling patients on wellness. CONCLUSION: Attendance at this participatory wellness CME program was associated with improved physician burnout, health behaviors in diet, stress, energy, quality of life, and wellness counseling.
RESUMO
BACKGROUND: Adverse childhood experiences (ACEs) are associated with the development of negative health behaviors and medical illnesses. ACE's association with poor health outcomes has been well documented in the general population; however, this relationship remains less clear in liver transplant (LT) recipients. OBJECTIVE: The aims of this study were to determine the prevalence of ACE and the influence of ACE on LT outcomes. METHODS: A retrospective electronic medical record review of all LT recipients over 11 years at an academic LT center. Demographic, diagnostic, and disease characteristics were extracted and compared for a history of ACE. Associations between a history of ACE and extracted variables were statistically tested using Student's t-test, chi-square tests, or Fisher's exact test, where appropriate. Graft and patient survival were tested using log-rank tests. RESULTS: Of the 1172 LT recipients, 24.1% endorsed a history of ACE. Females (P = 0.017) and recipients with lower levels of education (P < 0.001) had a higher frequency of ACE. Those with a history of ACE had a higher prevalence of hepatitis C virus (P < 0.001) and higher pretransplant body mass index (P < 0.001). Recipients with a history of ACE had higher prevalence of mood (P < 0.001), anxiety (P < 0.001), post traumatic stress disorder (P < 0.001), alcohol use (P < 0.001), and cannabis use (P < 0.001) disorders, as well as higher Patient Health Questionnaire-9 (P < 0.001) and General Anxiety Disorder-7 (P < 0.001) scores pre- and post-transplant. Those with ACE had a higher incidence of recorded relapses to alcohol by 3 years post-transplant (P = 0.027). Mean lab values, graft survival, and patient survival were not significantly different between those with and without a history of ACE except for total bilirubin at 6 months (P = 0.021). CONCLUSIONS: One-quarter of LT recipients have experienced ACE. ACE was associated with a history of psychiatric diagnoses, substance use disorders, elevated Patient Health Questionnaire-9 and General Anxiety Disorder-7 scores, and a higher prevalence of relapse to alcohol use after transplant. This population may benefit from increased/improved access to appropriate mental health and substance use services and support in the peri- and post-transplant period.
RESUMO
OBJECTIVE: To describe the outcomes of kidney transplant (KT) candidates with obesity undergoing sleeve gastrectomy (SG) to meet the criteria for KT. METHODS: Retrospective analysis was conducted of electronic medical records of KT candidates with obesity (body mass index >35 kg/m2) who underwent SG in our institution. Weight loss, adverse health events, and the listing and transplant rates were abstracted and compared with the nonsurgical cohort. RESULTS: The SG was performed in 54 patients; 50 patients did not have surgery. Baseline demographic characteristics were comparable at the time of evaluation. Mean body mass index ± SD of the SG group was 41.7±3.6 kg/m2 at baseline (vs 41.5±4.3 kg/m2 for nonsurgical controls); at 2 and 12 months after SG, it was 36.4±4.1 kg/m2 and 32.6±4.0 kg/m2 (P<.01 for both). In the median follow-up time of 15.5 months (interquartile range, 6.4 to 23.9 months), SG was followed by active listing (37/54 people), and 20 of 54 received KT during a median follow-up time of 20.9 months (interquartile range, 14.7 to 28.3 months) after SG. In contrast, 14 of 50 patients in the nonsurgical cohort were listed, and 5 received a KT (P<.01). Three patients (5.6%) experienced surgical complications. There was no difference in overall hospitalization rates and adverse health outcomes, but the SG cohort experienced a higher risk of clinically significant functional decline. CONCLUSION: In KT candidates with obesity, SG appears to be effective, with 37% of patients undergoing KT during the next 18 months (P<.01). Further research is needed to confirm and to improve the safety and efficacy of SG for patients with obesity seeking a KT.

Objective: Health coaching has the potential to improve self-management abilities (SM) in patients with Chronic Obstructive Pulmonary Disease (COPD). Patient engagement with health care providers has a beneficial effect on patient outcomes. We examined the association of patient engagement with the health coach on SM abilities in patients with COPD. Methods: We analyzed the association between the degree of engagement measured by the Working Alliance Inventory (WAI-SR) and the SM measured by the Self-Management-Ability-Scale-30 (SMAS-30) at the end of a COPD health coaching intervention. Results: The cohort included 146 moderate to severe COPD patients. The WAI-SR total score was 85% of the maximum possible scores indicating a high degree of engagement between the health coach and the patients. The WAI-SR Task and Bond domains were positively associated with SM abilities after adjusting for lung function (FEV1 %) and depression symptoms (PHQ-2). Conclusion: The degree of engagement between a health coach and patients is associated with the perception of SM abilities in patients with COPD. Our results may inform self-management intervention and clinical practice.
RESUMO
Background: Immigrants to the United States, on average, accumulate cardiovascular risk after resettlement, including obesity. There is a need to co-create interventions to address these disparities, and mood may be an important mediating factor. Methods: The Healthy Immigrant Community (HIC) study, set in southeast Minnesota, enrolled 475 adult participants in a weight loss intervention to reduce cardiovascular risk. Baseline questionnaires assessed mood, nutrition, physical activity, self-efficacy for healthy eating and physical activity, social support, and cohesion. A single-item mood rating of poor or fair was considered "negative", while ratings of good, very good, or excellent were considered "positive". Results: A total of 449 HIC participants (268 Hispanic/Latino and 181 Somali) with complete baseline measures and were included in this analysis. Participants endorsing negative mood compared to those endorsing positive mood had lower scores for healthy eating (p = 0.02) and physical activity levels (p = 0.03), lower confidence in eating a healthy diet (p = 0.001), and felt less of a sense of belonging to their community (p = 0.01). Those endorsing negative mood also reported receiving less social support from their family and friends to eat healthy (p = < 0.001) and be physically active (p = 0.01), and less often accessed community resources for healthy eating (p = 0.001) and physical activity (p = < 0.01) compared to participants reporting positive mood. Conclusions: Negative mood was associated with less healthy nutrition, lower confidence in eating healthy, sedentary lifestyle, and perceived lack of belonging to the community. Integrating mood management and self-efficacy strategies may enhance the effectiveness of lifestyle interventions among immigrants who report negative mood.

RESUMO
Bariatric surgery is increasingly recognized as a safe and effective treatment for obesity in patients with chronic kidney disease (CKD), including stages 4, 5, and 5D (on dialysis). Among the available surgical methods, sleeve gastrectomy (SG) is the most commonly performed weight loss procedure and is mainly done to facilitate kidney transplantation (KT). However, many KT candidates treated with SG remain on the transplant waiting list for months to years, with some never receiving a transplant. Therefore, appropriate candidates for SG must be selected, and post-SG management should address the unique needs of this population, with a focus on sustaining the metabolic benefits of surgery while minimizing potential side effects related to rapid weight loss which may inadvertently lead to muscle and bone catabolism. Multidisciplinary post-SG care in this population may lead to overall better health on the transplant waiting list, resulting in a higher percentage of post-SG patients ultimately receiving KT. To tailor the effective treatment for these patients, clinicians should acknowledge that patients with CKD stage 4-5D have different nutritional needs and are metabolically and psychosocially distinct from the general bariatric surgery population. Sarcopenia is highly prevalent and may be exacerbated by muscle catabolism following SG if not adequately addressed. Blood pressure, glucose, and bone metabolism are all affected by the CKD stage 4-5D, and therefore require distinct diagnostic and management approaches. Long-standing chronic disease, associated comorbidities, and low adherence to medical therapies require ongoing comprehensive psychosocial assessment and support. This paper aims to review and consolidate the existing literature concerning the intersection of CKD stage 4-5D and the consequences of SG. We also suggest future clinical outcome studies examining novel treatment approaches for this medically complex population.

BACKGROUND: Immigrants to the United States face structural barriers that contribute to rising cardiovascular risk factors and obesity after immigration. This manuscript describes the development of the Healthy Immigrant Community protocol and baseline measures for a stepped wedge cluster randomized trial to test the effectiveness of a social network intervention for cardiovascular risk reduction among two immigrant populations. METHODS: We developed a social network-informed, community-based, participatory research-derived health promotion intervention with Hispanic and Somali immigrant communities in Minnesota consisting of mentoring, educational and motivational sessions, group activities, and a community toolkit for healthy weight loss delivered by culturally concordant health promoters (HPs) to their social networks. Using a stepped wedge cluster randomized design, social network-based groups were randomly assigned to receive the intervention either immediately or after a delay of one year. Outcomes, measured at baseline, 6 months, 12 months, and 24 months, were derived from the American Heart Association's "Life's Simple 7": BMI and waist circumference, blood pressure, fasting blood glucose, total cholesterol, physical activity level, and dietary quality. RESULTS: A total of 51 HPs were enrolled and randomized (29 Hispanic; 22 Somali). There were 475 participants enrolled in the study, representing a mean social network group size of 8 (range, 5-12). The mean BMI of the sample (32.2) was in the "obese" range. CONCLUSION: Processes and products from this Healthy Immigrant Community protocol are relevant to other communities seeking to reduce cardiovascular risk factors and negative health behaviors among immigrant populations by leveraging the influence of their social networks.

Objectives: Our aim was to examine the relationship between weight concerns (WC) and smoking cessation. Methods: WC was assessed before smoking cessation treatment in 671 adult patients who completed a 12-month follow-up visit at the Centre for Tobacco-Dependent, Prague, Czech Republic, from 2013 through 2019. We evaluated the abstinence rate at 12-month follow-up. Results: Among 669 patients with baseline WC (mean age, 43.4 years), 47% were women (145/306) and 21% were men (78/363). No association existed between WC and abstinence at 12 months. Smokers with obesity had increased fear of gaining weight (34% versus 24% of overweight and 23% of healthy-weight smokers) (p=.034) and were less confident in their ability to maintain their current weight (36% versus 55% of overweight smokers and 59% of healthy- weight smokers) (p<.001). Conclusions: Many smokers are concerned about gaining weight after stopping smoking, but in this cohort of patients, having WC was not associated with 12-month abstinence, but obesity or overweight was related to being afraid of postcessation weight-gain and low confidence for maintaining weight. Practitioners should be aware of the prevalence of WC in those stopping smoking and should address concerns, such as poor motivation and low confidence about managing their weight.

Background: Lifestyle interventions for weight loss are currently not individualised to underlying pathophysiology and behavioral traits in obesity. We aim to compare the outcome of a standard lifestyle intervention (SLI) to phenotype-tailored lifestyle interventions (PLI) on weight loss, cardiometabolic risk factors and physiologic variables contributing to obesity. Methods: This 12-week, single-centre non-randomised proof-of-concept clinical trial including men and women aged 18-65 years with a body mass index (BMI) greater than 30 without history of any bariatric procedure, and current use of any medication known to affect weight. Participants lived anywhere in the United States, and underwent in-person testing in Rochester, MN at a teaching hospital. All participants completed in-person phenotype testing at baseline and after 12 weeks. Participants were assigned to their intervention based on their period of enrollment. In the first phase, participants were assigned to SLI with a low-calorie diet (LCD), moderate physical activity, and weekly behavioral therapy sessions. In the second phase, other participants were assigned to PLI according to phenotype: abnormal satiation (time-restricted volumetric LCD); abnormal postprandial satiety (LCD with pre-meal protein supplementation); emotional eating (LCD with intensive behavioral therapy); and abnormal resting energy expenditure (LCD with post-workout protein supplementation and high-intensity interval training). The primary outcome was total body weight loss in kg at 12 weeks using multiple imputation for missing data. Linear models estimated the association of study group allocation and study endpoints adjusting for age, sex, and baseline weight. This study was registered with ClinicalTrials.gov, NCT04073394. Findings: Between July 2020 and August 2021, 211 participants were screened, and 165 were assigned to one of the two treatments in the two phases: 81 SLI (mean [SD] age 42.9 [12] years; 79% women; BMI 38.0 [6.0]) and 84 PLI (age 44.8 [12.2] years; 83% women; BMI 38.7 [6.9]); 146 completed the 12-week programs. The weight loss was -7.4 kg (95%CI, -8.8, -6.0) with PLI vs. -4.3 kg (95%CI, -5.8, -2.7) with SLI (difference, -3.1 kg [95%CI, -5.1 to -1.1]; P = 0.004). No adverse events were reported in any group. Interpretation: Phenotype-tailored lifestyle interventions may result in significant weight loss, but a randomised controlled trial is required to confirm causality. Funding: Mayo Clinic; NIH (K23-DK114460).
RESUMO
OBJECTIVE: Faculty development is designed to facilitate career advancement of junior faculty but there is limited empirical evidence on how to design an effective program. METHODS: As a first step in the design of an effective program, a needs assessment was conducted. Participants were faculty members of an academic psychiatry department. Participants completed a quantitative and qualitative survey assessing their experience with mentors, academic self-efficacy, career burnout and satisfaction, academic productivity, and perceived barriers to scholarship. RESULTS: Eighty percent (N = 104) of eligible faculty members completed the study survey (54% female; 81% White, 10% underrepresented in medicine). Less than half of the respondents (44%) reported having a current mentor. Number of mentors (r = .33; p < .01), mentorship meetings (r = .35; p < .01), and mentorship quality (r = .33; p < .01) were significantly correlated to a standardized measure of academic self-efficacy. Self-efficacy was significantly associated with academic productivity (r = .44; p < .001) and career satisfaction (r = .29; p < .05). The top barriers to scholarship productivity were time and lack of access to resources. Faculty members without a mentor endorsed more barriers to scholarship (p < .001) than those with a mentor. Themes that emerged from the qualitative data suggest that mentorship supports career advancement through coaching and professional development, invitations to collaborate and resource share, networking, and active teaching. CONCLUSION: Based on the relationship of mentoring to career outcomes, a robust faculty development program needs a formal academic mentorship program to improve career satisfaction and academic productivity.

PURPOSE OF REVIEW: This review highlights the salient data of the psychosocial concerns that influence outcomes of bariatric surgery and organ transplantation. RECENT FINDINGS: Bariatric surgery has emerged as an important intervention with data supporting substantial and sustained weight loss, enhanced quality of life, remission of obesity-related medical comorbidities, and improved long-term patient and graft survival in transplant patients. Depression, suicide, anxiety, posttraumatic stress disorder, alcohol use, adherence, and psychopharmacology considerations can influence outcomes of both these surgeries. SUMMARY: Obesity is increasingly prevalent among patients pursuing transplantation surgery, and it is often a factor in why a patient needs a transplant. However, obesity can be a barrier to receiving a transplant, with many centers implementing BMI criteria for surgery. Furthermore, obesity and obesity-related comorbidities after transplant can cause poor outcomes. In this context, many transplant centers have created programs that incorporate interventions (such as bariatric surgery) that target obesity in transplant candidates. A presurgery psychosocial assessment is an integral (and required) part of the process towards receiving a bariatric surgery and/or a transplantation surgery. When conducting a dual (bariatric and transplantation surgery) psychosocial assessment, it is prudent to understand the overlap and differentiation of specific psychosocial components that influence outcomes in these procedures.

Weight regain after bariatric surgery is associated with problematic eating behaviors that have either recurred after a period of improvement or are new-onset behaviors. Problematic eating behaviors after bariatric surgery have been conceptualized in different ways in the literature, such as having a food addiction and experiencing a loss of control of eating. The intersection of these constructs appears to be driven overeating defined as patients' experiences of reduced control of their eating which results in overeating behavior. The purpose of this review is to define patient experiences of driven overeating through the behavioral expression of emotion-based eating, reward-based eating, and executive functioning deficits-namely impulsivity-which is associated with weight regain after having bariatric surgery. Delineating concepts in this way and determining treatment strategies accordingly may reduce distress related to the inevitable return of increased hunger, cravings, portion sizes, and tolerance for highly palatable foods after surgery. Along with standard behavioral weight maintenance strategies, topics including acceptance, motivation, emotion-based eating, reward-based/impulsive eating, physical activity, and self-compassion are discussed. These concepts have been adapted for patients experiencing weight regain after having bariatric surgery and may be particularly helpful in attenuating driven overeating and weight regain.

OBJECTIVE: This study aimed to determine the effects of a long-acting glucagon-like peptide-1 (GLP-1) receptor agonist, liraglutide, and placebo subcutaneously over 16 weeks on weight and gastric functions and to evaluate associations of single-nucleotide polymorphisms in GLP1R (rs6923761) and TCF7L2 (rs7903146) with effects of liraglutide. METHODS: The study conducted a randomized, parallel-group, placebo-controlled, 16-week trial of liraglutide, escalated to 3 mg subcutaneously daily in 136 otherwise healthy adults with obesity. Weight, gastric emptying of solids (GES), gastric volumes, satiation, and body composition measured at baseline and after treatment were compared in two treatment groups using analysis of covariance. RESULTS: Liraglutide (n = 59) and placebo (n = 65) groups completed treatment. Relative to placebo, liraglutide increased weight loss at 5 and 16 weeks (both p < 0.05), slowed time to half GES (T1/2 ) at 5 and 16 weeks (both p < 0.001), and increased fasting gastric volume (p = 0.01) and satiation (p < 0.01) at 16 weeks. GES T1/2 was positively correlated with weight loss on liraglutide (both p < 0.001). After 16 weeks of liraglutide, GLP1R rs6923761 (AG/AA vs. GG) was associated with reduced percent body fat (p = 0.062), and TCF7L2 rs7903146 (CC vs. CT/TT) was associated with lower body weight (p = 0.015). CONCLUSIONS: Liraglutide, 3 mg, induces weight loss with delay in GES T1/2 and reduces calorie intake. Slowing GES and variations in GLP1R and TCF7L2 are associated with liraglutide effects in obesity.

BACKGROUND: Long-term weight maintenance after weight loss is challenging, and innovative solutions are required. Digital technologies can support behavior change and, therefore, have the potential to be an effective tool for weight loss maintenance. However, to create meaningful and effective digital behavior change interventions that support end user values and needs, a combination of persuasive system design (PSD) principles and behavior change techniques (BCTs) might be needed. OBJECTIVE: This study aimed to investigate how an evidence-informed digital behavior change intervention can be designed and developed by combining PSD principles and BCTs into design features to support end user values and needs for long-term weight loss maintenance. METHODS: This study presents a concept for how PSD principles and BCTs can be translated into design features by combining design thinking and Agile methods to develop and deliver an evidence-informed digital behavior change intervention aimed at supporting weight maintenance. Overall, 45 stakeholders participated in the systematic and iterative development process comprising co-design workshops, prototyping, Agile development, and usability testing. This included prospective end users (n=17, 38%; ie, people with obesity who had lost ≥8% of their weight), health care providers (n=9, 20%), healthy volunteers (n=4, 9%), a service designer (n=1, 2%), and stakeholders from the multidisciplinary research and development team (n=14, 31%; ie, software developers; digital designers; and eHealth, behavior change, and obesity experts). Stakeholder input on how to operationalize the design features and optimize the technology was examined through formative evaluation and qualitative analyses using rapid and in-depth analysis approaches. RESULTS: A total of 17 design features combining PSD principles and BCTs were identified as important to support end user values and needs based on stakeholder input during the design and development of eCHANGE, a digital intervention to support long-term weight loss maintenance. The design features were combined into 4 main intervention components: Week Plan, My Overview, Knowledge and Skills, and Virtual Coach and Smart Feedback System. To support a healthy lifestyle and continued behavior change to maintain weight, PSD principles such as tailoring, personalization, self-monitoring, reminders, rewards, rehearsal, praise, and suggestions were combined and implemented into the design features together with BCTs from the clusters of goals and planning, feedback and monitoring, social support, repetition and substitution, shaping knowledge, natural consequences, associations, antecedents, identity, and self-belief. CONCLUSIONS: Combining and implementing PSD principles and BCTs in digital interventions aimed at supporting sustainable behavior change may contribute to the design of engaging and motivating interventions in line with end user values and needs. As such, the design and development of the eCHANGE intervention can provide valuable input for future design and tailoring of evidence-informed digital interventions, even beyond digital interventions in support of health behavior change and long-term weight loss maintenance.

RESUMO
Coronary artery disease continues to be a major cause of morbidity and mortality despite significant advances in risk stratification and management. This has prompted the search for alternative nonconventional risk factors that may provide novel therapeutic targets. Psychosocial stress, or mental stress, has emerged as an important risk factor implicated in a higher incidence of cardiovascular events, and although our understanding of this far ranging and interesting phenomenon has developed greatly over recent times, there is still much to be learned regarding how to measure mental stress and how it may impact physical health. With the current coronavirus disease 2019 global pandemic and its incumbent lockdowns and social distancing, understanding the potentially harmful biological effects of stress related to life-changing events and social isolation has become even more important. In the current review our multidisciplinary team discusses stress from a psychosocial perspective and aims to define psychological stress as rigorously as possible; discuss the pathophysiologic mechanisms by which stress may mediate cardiovascular disease, with a particular focus to its effects on vascular health; outline existing methods and approaches to quantify stress by means of a vascular biomarker; outline the mechanisms whereby psychosocial stressors may have their pathologic effects ultimately transduced to the vasculature through the neuroendocrine immunologic axis; highlight areas for improvement to refine existing approaches in clinical research when studying the consequences of psychological stress on cardiovascular health; and discuss evidence-based therapies directed at reducing the deleterious effects of mental stress including those that target endothelial dysfunction. To this end we searched PubMed and Google Scholar to identify studies evaluating the relationship between mental or psychosocial stress and cardiovascular disease with a particular focus on vascular health. Search terms included "myocardial ischemia," "coronary artery disease," "mental stress," "psychological stress," "mental∗ stress∗," "psychologic∗ stress∗," and "cardiovascular disease∗." The search was limited to studies published in English in peer-reviewed journals between 1990 and the present day. To identify potential studies not captured by our database search strategy, we also searched studies listed in the bibliography of relevant publications and reviews.

OBJECTIVES: Recognizing bipolar disorder as a multi-system metabolic condition driven, in part, by binge eating behavior and atypical depressive symptoms, this study aimed to quantify diet quality and evaluate clinical correlates in a bipolar disorder cohort. METHODS: Participants from the Mayo Clinic Bipolar Disorder Biobank (n = 734) completed the Rapid Eating Assessment for Participants - Shortened version (REAP-S) to determine diet quality. The average REAP-S score for a U.S. omnivorous diet is 32 (range 13 to 39) with higher scores indicating healthier diet. Demographic variables were collected in a standardized clinical questionnaire. Depressive symptoms were assessed by the Bipolar Inventory of Symptoms Scale. Cardiometabolic variables were retrieved from the electronic health record. Associations between continuous variables and REAP-S scores (total, 'healthy foods' and 'avoidance of unhealthy foods') were assessed using linear regression. RESULTS: Overall, our sample had a mean REAP-S score of 27.6 (4.9), suggestive of a lower diet quality than the average general population in the US. There was a significant inverse relationship between mean REAP-S lower scores with increased BMI, waist circumference, disordered eating and depression. All these associations were significantly stronger in female participants. LIMITATIONS: EHR cross-sectional data. CONCLUSIONS: Our data suggest unhealthy diet quality in bipolar disorder is associated with depression, obesity and cardiometabolic abnormalities. Additional work is encouraged to prospectively track mood and diet quality to further understand the bidirectional relationship and clarify if dietary interventions can positively impact mood. Further delineating potential sex differences in diet quality and depression may provide greater appreciation of modifiable risk factors for future cardiometabolic burden.
