Objective: To identify an efficacious intervention on treating adolescents with overweight and obesity, this might result in health benefits. Methods: Adolescents with overweight or obesity aged 10–17 years with BMI percentile ≥85th were included in this historical observational analysis. Subjects used an entirely remote weight loss program combining mobile applications, frequent self-weighing, and calorie restriction with meal replacement. Body weight changes were evaluated at 42, 60, 90, and 120 days using different metrics including absolute body weight, BMI, and BMI z-score. Chi-square or Fisher exact tests (categorical variables) and Student's t -test (continuous variables) were used to compare subjects. Results: In total, 2,825 participants, mean age 14.4 ± 2.2 years, (54.8% girls), were included from October 27, 2016, to December 31, 2017, in mainland China; 1355 (48.0%) had a baseline BMI percentile ≥97th. Mean BMI and BMI z-score were 29.20 ± 4.44 kg/m 2 and 1.89 ± 0.42, respectively. At day 120, mean reduction in body weight, BMI, and BMI z-score was 8.6 ± 0.63 kg, 3.13 ± 0.21 kg/m 2 , and 0.42 ± 0.03; 71.4% had lost ≥5% body weight, 69.4% of boys and 73.2% of girls, respectively. Compared with boys, girls achieved greater reduction on BMI z-score at all intervals ( p < 0.004 for all comparisons). Higher BMI percentile at baseline and increased frequency of use of the mobile application were directly associated with more significant weight loss. Conclusions: An entirely remote digital weight loss program is effective in facilitating weight loss in adolescents with overweight or obesity in the short term and mid term.
Cardiac Rehabilitation Referral and Participation Rates for Heart Failure With Reduced Ejection Fraction
Journal of Cardiopulmonary Rehabilitation and Prevention | March 2, 2021 | Volume: 41 | Issue: 2 | Pages: 126-127
Abstract Aims/Hypothesis The need for understanding obesity as a chronic disease, its stigmatization, and the lack of actionability related to it demands a new approach. The adiposity‐based chronic disease (ABCD) model is based on adiposity amount, distribution, and function, with a three stage complication‐centric rather than a body mass index (BMI)‐centric approach. The prevalence rates and associated risk factors are presented. Methods In total, 2159 participants were randomly selected from Czechia. ABCD was established as BMI ≥ 25 kg/m 2 or high body fat percent, or abdominal obesity and then categorized by their adiposity‐based complications: Stage 0: none; Stage 1: mild/moderate; Stage 2: severe. Results ABCD prevalence was 62.8%. Stage 0 was 2.3%; Stage 1 was 31.4%; Stage 2 was 29.1%. Comparing with other classifiers, participants in Stage 2 were more likely to have diabetes, hypertension, and metabolic syndrome than those with overweight, obesity, abdominal obesity, and increased fat mass. ABCD showed the highest sensitivity and specificity to detect participants with peripheral artery disease, increased intima media, and vascular disease. Conclusion/Interpretation The ABCD model provides a more sensitive approach that facilitates the early detection and stratification of participants at risk compared to traditional classifiers.
Ceramide Scores Predict Cardiovascular Risk in the Community
Arteriosclerosis, Thrombosis, and Vascular Biology | February 18, 2021 | Volume: 41 | Issue: 4 | Pages: 1558-1569
Objective: Cardiovascular disease remains a leading cause of mortality worldwide. Ceramide scores have been associated with adverse outcomes in patients with established coronary artery disease. The prognostic value of ceramide score has not been assessed in the general population. We tested the hypothesis that ceramide scores are associated with major adverse cardiac events (MACE) in a community-based cohort with average coronary artery disease burden at enrollment. Approach and results: In a prospective community-based cohort, we performed passive follow-up using a record linkage system to ascertain the composite outcome of MACE, defined as acute myocardial infarction, coronary revascularization (bypass grafting or percutaneous intervention), stroke, or death. Ceramides were analyzed as log-transformed continuous variables, ratios or scores, and quartiles with adjustment for confounders. We analyzed 1131 subjects, 52% females, mean age±(SD) 64±9 years. After a median follow-up of 13.3 years (Q1, 12.7; Q3, 14.4), 486 patients experienced a MACE: myocardial infarction (80), coronary artery bypass surgery (34), percutaneous coronary intervention (62), stroke (94), and all-cause death (362). Ceramide ratios were significantly associated with MACE independently of LDL-c (low-density lipoprotein cholesterol) and conventional coronary artery disease risk factors. Those in the highest quartile of ceramide score had nearly 1.5-fold risk of MACE, hazard ratio, 1.47 (95% CI, 1.12–1.92). There was a dose-response association across quartiles of ceramide ratios and MACE. Conclusions: Elevated ceramide score is a robust predictor of cardiovascular disease and MACE in the community. The risk conferred by the ceramide score has a dose-response behavior and is independent of conventional risk factors.
Real-World Experiences With Yoga on Cancer-Related Symptoms in Women With Breast Cancer
Global Advances in Health and Medicine | January 13, 2021 | Volume: 10 | Issue: No issue available | Pages: No page available
Purpose Integrative therapies such as yoga are potential treatments for many psychological and physical symptoms that occur during and/or after treatment for cancer. The purpose of the current study was to evaluate the patient-perceived benefit of yoga for symptoms commonly experienced by breast cancer survivors. Methods 1,049 breast cancer survivors who had self-reported use of yoga on a follow up survey, in an ongoing prospective Mayo Clinic Breast Disease Registry (MCBDR), received an additional mailed yoga-focused survey asking about the impact of yoga on a variety of symptoms. Differences between pre- and post- scores were assessed using Wilcoxon Signed Rank Test. Results 802/1,049 (76%) of women who were approached to participate, consented and returned the survey. 507/802 (63%) reported use of yoga during and/or after their cancer diagnosis. The vast majority of respondents (89.4%) reported some symptomatic benefit from yoga. The most common symptoms that prompted the use of yoga were breast/chest wall pain, lymphedema, and anxiety. Only 9% of patients reported that they had been referred to yoga by a medical professional. While the greatest symptom improvement was reported with breast/chest wall pain and anxiety, significant improvement was also perceived in joint pain, muscle pain, fatigue, headache, quality of life, hot flashes, nausea/vomiting, depression, insomnia, lymphedema, and peripheral neuropathy, (all p-values <0.004). Conclusion Data supporting the use of yoga for symptom management after cancer are limited and typically focus on mental health. In this study, users of yoga often reported physical benefits as well as mental health benefits. Further prospective studies investigating the efficacy of yoga in survivorship are warranted.
Evaluating the sensitivity of the ACC/AHA pooled cohort risk calculator to predict atherosclerotic cardiovascular events within 10 years: how many events are we failing to predict?
European Heart Journal | November 26, 2020 | Volume: 41 | Issue: Supplement_2 | Pages: No page available
Abstract Background The ACC/AHA Pooled Cohort Equation (PCE) for atherosclerotic cardiovascular disease (ASCVD) has been recommended as the initial step in cardiovascular risk assessment. The sensitivity of this tool to detect those who will develop ASCVD within 10-years, while considering age and sex groups, has not been extensively studied. Methods Using the Rochester Epidemiology Project (REP) we evaluated a community-based cohort of consecutive patients that sought primary care in Olmsted County, MN, between the years 1998–2000 and were followed up through March 1st 2016. Inclusion criteria were ages 40–79 and complete data to calculate the PCE. We excluded those with known ASCVD, atrial fibrillation or heart failure. Criteria were similar to those used to derive the PCE. Events were validated in duplicate and included fatal and non-fatal myocardial infarction and ischemic stroke. Patient information was ascertained using the record linkage system of the REP. Follow-up was truncated at 10 years. We assessed the ASCVD predicted risk (categorized as low <5%, intermediate 5–9.9%, high 10–19.9%, and very high ≥20% risk) at baseline, in subjects having an ASCVD event within 10-years in the community across age (<65 years) and sex categories. We also categorized ideal cardiovascular health as ≥4 metrics [non-smoker, body mass index <25 kg/m2, and not having of elevated blood pressure (≥130/80 mmHg), LDL cholesterol (>100 mg/dL), or fasting blood glucose (>100 mg/dL), in the absence of a medical diagnosis or treatment]. Results We included 30,042 adults, mean ± SD age 48.5±12.2 years, 54% women, with a median follow-up of 16.5±5.3 years. There were 1,555 ASCVD events (5.2%) at 10 years of follow-up. The performance of the PCE was similar to what was described in the original report (0.78 vs 0.79). Overall, among those who suffered an ASCVD, 54% of women and 41% of men were not high risk as predicted by PCE (Figure 1A). Most women (73%) <65 years of age would had been considered low risk within 10-years before the event, and only 10% would have been considered to be high risks (Figure 1B). Nonetheless, women <65 years who had an ASCVD event and low 10-year predicted ASCVD risk by PCE were less likely to have ideal cardiovascular health [55 (0.40%) vs 3884 (28.39%), p-value<0.0001], when compared to women in the low risk category without an event. Conclusion The PCE fails to identify most women who will develop an ASCVD event, particularly women <65 years of age. These results underscore the importance of using additional information when estimating ASCVD risk among women and the need for better cardiovascular risk prediction tools.

Characteristics of cardiac rehabilitation programs in Latin America and the Caribbean, and estimation of capacity and needs in the region
European Heart Journal | November 26, 2020 | Volume: 41 | Issue: Supplement_2 | Pages: No page available
Abstract Background Cardiac rehabilitation (CR) is an established model of cardiovascular (CV) prevention that has proven benefits. Availability, characteristics and need of CR programs in Latin-American and Caribbean (LAC) countries remains poorly characterized. This study aims to establish the availability, capacity, density and aspects of CR delivery in LAC. Methods A cross-sectional survey was administered to CR programs in 24 LAC. Local CV organizations and societies identified CR programs. Characteristics of individual CR program were reviewed including: funding sources, core components, healthcare providers, and dose (number of sessions per weeks X total number of weeks) of CR. National CR capacity (median number of patients a program could serve per year X number of programs per country), density (Ischemic Heart Disease [IHD] incidence per year/ national capacity), need (IHD incidence per year- national capacity) and occupancy (median number patients program served per year/national capacity) were computed based on survey responses. Results At least one CR program was identified per LAC country (total 255 programs across 24 countries). Data was collected in 20 of the 24 countries. Responses were received from 139/255 programs (median program response rate=55%; Table 1). Over 50% (n=73) of programs were funded by multiple sources (government, hospital/clinic, private health insurance); Self-payment was reported by 63% programs, in which 24 (33.8%) patients paid over 50% of the cost. Guideline-indicated conditions were accepted in 77% or more programs. Physiotherapists (n=106, 76.3%), cardiologists (n=105, 75.5%) and dietitians (n=79, 56.8%) were the most common healthcare providers on CR teams. Regionally, programs offered 9 (IQR = 8–10) core components (patient education, exercise prescription and initial assessment delivered by nearly all programs). Median CR was 36 (IQR = 24–56) sessions/patient. Twenty-seven (20.9%) programs offered alternative CR models (e.g., home or community-based and hybrid models). Median national capacity was 500 CR spots/country (IQR= 200–2300). Regional density was 1 CR spot per 24 incident IHD patients per year. Greatest need in absolute terms for CR was observed in Brazil, Dominican Republic and Mexico (all with >150,000 spots needed per year to manage incident IHD patients; Table 1). Occupancy ranged from over 100% in Colombia to 15% in Chile (median=60%, IQR = 32%–81%), Table 1. Conclusion In LAC countries, there is very limited capacity to meet the need for CR. Nature of CR services varied regionally. Funding Acknowledgement Type of funding source: None
The association of artificial intelligence-enabled electrocardiogram-derived age (physiologic age) with atherosclerotic cardiovascular events in the community
European Heart Journal | November 26, 2020 | Volume: 41 | Issue: Supplement_2 | Pages: No page available
Abstract Background We have demonstrated that artificial intelligence interpretation of ECGs (AI-ECG) can estimate an individual's physiologic age and that the gap between AI-ECG and chronologic age (Age-Gap) is associated with increased mortality. We hypothesized that Age-Gap would predict long-term atherosclerotic cardiovascular disease (ASCVD) and that Age-Gap would refine the ACC/AHA Pooled Cohort Equations' (PCE) predictive abilities. Methods Using the Rochester Epidemiology Project (REP) we evaluated a community-based cohort of consecutive patients seeking primary care between 1998–2000 and followed through March 2016. Inclusion criteria were age 40–79 and complete data to calculate PCE. We excluded those with known ASCVD, AF, HF or an event within 30 days of baseline.A neural network, trained, validated, and tested in an independent cohort of ∼ 500,000 independent patients, using 10-second digital samples of raw, 12 lead ECGs. PCE was categorized as low<5%, intermediate 5–9.9%, high 10–19.9%, and very high≥20%. The primary endpoint was ASCVD and included fatal and non-fatal myocardial infarction and ischemic stroke; the secondary endpoint also included coronary revascularization [Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Graft (CABG)], TIA and Cardiovascular mortality. Events were validated in duplicate. Follow-up was truncated at 10 years for PCE analysis. The association between Age-Gap with ASCVD and expanded ASCVD was assessed with cox proportional hazard models that adjusted for chronological age, sex and risk factors. Models were stratified by PCE risk categories to evaluate the effect of PCE predicted risk. Results We included 24,793 patients (54% women, 95% Caucasian) with mean follow up of 12.6±5.1 years. 2,366 (9.5%) developed ASCVD events and 3,401 (13.7%) the expanded ASCVD. Mean chronologic age was 53.6±11.6 years and the AI-ECG age was 54.5±10.9 years, R2=0.7865, p<0.0001. The mean Age-Gap was 0.87±7.38 years. After adjusting for age and sex, those considered older by ECG, compared to their chronologic age had a higher risk for ASCVD when compared to those with <−2 SD age gap (considered younger by ECG). (Figure 1A), with similar results when using the expanded definition of ASCVD (data not shown). Furthermore, Age-Gap enhanced predicted capabilities of the PCE among those with low 10-year predicted risk (<5%): Age and sex adjusted HR 4.73, 95% CI 1.42–15.74, p-value=0.01 and among those with high predicted risk (>20%) age and sex adjusted HR 6.90, 95% CI 1.98–24.08, p-value=0.0006, when comparing those older to younger by ECG respectively (Figure 1B). Conclusion The difference between physiologic AI-ECG age and chronologic age is associated with long-term ASCVD, and enhances current risk calculators (PCE) ability to identify high and low risk individuals. This may help identify individuals who should or should not be treated with newer, expensive risk-reducing therapies. Funding Acknowledgement Type of funding source: Foundation.

Internal Medicine Physicians and Social media: Knowledge, Skills, and Attitudes
Journal of Primary Care & Community Health | October 31, 2020 | Volume: 11 | Issue: No issue available | Pages: No page available
Objective Increasing adoption of social media have revolutionized communications between individuals, groups, and organizations This research study was designed to assess the knowledge, skills, and attitudes of internal medicine physicians’ awareness and engagement with social media (sometimes referred to as #SoMe) within the digital landscape of healthcare delivery. Methods An audience-response survey focused on social media “ Social media in Healthcare: Physician Survey,” was administered during the “A Systematic Approach to Medically Unexplained Symptoms” continuing medical education conference. The Conference took place between August 22, 2019 and August 24, 2019. Data was collected on August 23, 2019. A range of 103 (59.5%) to 112 (64.7%) of the total 173 attendees participated in this cross-sectional audience-response survey, depending on the questions answered. Results Most responders were between the ages of 35 and 65 years (79.6%) and female (60.2%). A majority of responders were aware of social media terminology (88.7%), and many had used it personally (46.7%), but only 12% knew how to use social media to search medical topics, 18% used it to network professionally and most (68.9%) had a distrust of social media when it came to the protection of their privacy or their patients’ privacy. Overall, about 29.6% indicated an interest in future continued medical education focused on social media (and 27.4% were neutral). Conclusions Approximately half of the responders used social media but far less engaged its platforms for professional use likely due to privacy related concerns. Distance from academic institutions, where professional social media use is more common likely, played a role in aversion. Awareness of social media’s role in healthcare has increased among physicians in practice, however their participation and knowledge of opportunities remains limited.
Calf muscle pump function as a predictor of all-cause mortality
Vascular Medicine | September 25, 2020 | Volume: 25 | Issue: 6 | Pages: 519-526
Calf muscle pump (CMP) promotes venous return from the lower extremity and contributes to preload and cardiac output. Impaired CMP function may reflect a measure of frailty or cumulative disease burden or may impede cardiac function. The study objective was to test the hypothesis that impaired CMP negatively impacts survival. Consecutive adult patients who underwent venous strain gauge plethysmography at the Mayo Clinic Gonda Vascular Laboratory (January 1, 1998 – December 31, 2011) were assessed for overall survival. Patients with venous incompetence, venous obstruction or unilateral calf pump dysfunction were excluded. Risk of mortality was assessed with Cox proportional hazard ratios and after adjusting for Charlson Comorbidity Index variables. Over the study period, 2728 patients were included in the analysis. Compared to patients with normal CMP, those with impaired CMP were older ( p < 0.001), predominantly female ( p = 0.01) and had higher mean Charlson scores ( p < 0.001). Patients with impaired CMP had a higher mortality rate at 5 (8.9% vs 2.4%), 10 (17.5% vs 5.9%), and 15 years (22.8% vs 8.3%) compared to those with normal CMP ( p < 0.001 for each comparison). Of patients with heart failure, those with impaired CMP had worse survival at each 5-year increment compared to those with normal CMP ( p < 0.05 at each increment). In conclusion, impaired CMP appears to be an independent predictor of poor outcomes after adjusting for variables within the Charlson Comorbidity Index. The association between impaired CMP, heart failure, and mortality may represent a negative impact on circulatory function or a surrogate measure of frailty.
