Effects of a comprehensive structured patient education intervention on disease-related knowledge and behaviour change among people living with type 2 diabetes in the Philippines.

Introduction: Addressing the ongoing needs of individuals with diabetes, particularly in low- and middle-income countries like the Philippines, requires a focus on regular follow-ups with healthcare teams, adherence to healthy behaviors, and effective patient education to prevent long-term complications. The aim of this study was to ascertain the impact of a comprehensive educational program for those living with diabetes in the Philippines. Methods: In a prospective study, a convenience sample of patients living with diabetes attending a cardiac rehabilitation or an outpatient diabetes clinic in the Philippines received a 12-week education intervention. Participants completed surveys at pre- and post-intervention assessing disease-related knowledge, health literacy, dietary habits, and tobacco use. Physical activity was measured by steps taken per day using wearable devices and by self-report of minutes of moderate or vigorous-intensity exercise per week. Satisfaction with the educational materials was also evaluated by a survey composed of Likert-type scale and open-ended questions. Descriptive statistics, paired t-tests or chi-square were used for data analysis. Results: Overall, 184 individuals living with diabetes type 2 (mean age = 54.4 ± 12.4, 32% female) completed both assessments. There was significant improvement in disease-related knowledge (p < 0.001), daily steps measured by a wearable device and self-reported minutes of moderate/vigorous-intensity exercise (p < 0.001), and the number of fruit and vegetable servings consumed per day (p = 0.001). No significant changes were observed in health literacy levels. One participant stopped using tobacco at post-education. Educational materials were highly satisfactory to participants. Lack of time, family responsibilities, and poor internet access were the main barriers to learning reported by participants. Suggestions to improve the education provided included assessment of information needs at the start of the education, having short summaries about the topics, follow-ups post-intervention, and inviting family members to sessions. Discussion: Results of this study demonstrated the positive effects a comprehensive structured patient education intervention on disease-related knowledge and behaviour changes among people living with type 2 diabetes in the Philippines.

Sex differences and predictors of completion of a 6-month exercise-based cardiac rehabilitation program in 1,536 people following stroke.

OBJECTIVE: To retrospectively examine sex-differences and predictors of completion in consecutively-referred patients to a 6-month exercise-based cardiac rehabilitation program (CRP) from 2006 to 2017. MATERIALS/METHODS: People with hemiplegic gait participated in stroke-adapted-CRP; otherwise, traditional-CRP. Reasons for non-completion were ascertained by interview. Regression-analyses were conducted to determine non-completion in all patients and women and men separately. RESULTS: There were 1536 patients (30.3% women), mean age 64.5 ± 12.5 with 23% initiating the stroke-adapted-CRP. Overall, 75.1% completed the CRP (87.3% stroke-adapted-CRP vs 71.5% traditional-CRP; p < .001). There was no difference in completion between women and men (74.5% vs 75.4%; p=0.7), or in attendance to pre-scheduled sessions (p=0.6) or reasons for non-completion (p > .05, all). The only sex difference in completion by age (decade) occurred in those <41 years (59% women vs 85% men; p=.02). Baseline predictors of non-completion among all patients included not being enrolled in the stroke-adapted-CRP, lower V̇O2peak, smoking, diabetes (prescribed insulin) and depression but not sex (p=.5) or age (p=.15). Unique predictors in women vs men were younger age, lower V̇O2peak, smoking, diabetes (prescribed insulin), depression, and cancer diagnoses. Unique to men was having >1 stroke and diabetes (any anti-diabetes medication). The strongest predictor of non-completion among all models was not being enrolled in stroke-adapted-CRP. CONCLUSIONS: While there were no sex-differences in adherence to the CRP, women and men have mostly unique predictors of non-completion. Younger women are at greatest risk for non-completion. Practitioners should provide sex-specific, tailored strategies for enhancing completion with a focus on younger women and offering a stroke-adapted-CRP with close attention to those with diabetes.

The Diversity of Vasectomy Reversal Providers and Their Web-based Advertising Habits in the United States.

OBJECTIVE: To better understand the internet advertising material published on clinician websites for the 30,000 men who undergo evaluation for vasectomy reversal (VR), which is a technically demanding procedure requiring microsurgical expertise. METHODS: Internet search trends for "vasectomy" and "vasectomy reversal" from 2004 to 2022 were assessed using Google Trends. Search engines were then queried on a state-by-state basis for physicians performing VR and the available information aggregated and analyzed using standard statistical approaches. RESULTS: VR search volume consistently represented roughly one-tenth of the search volume for vasectomy. One hundred and ninety reversal clinics were identified in 44 of 50 states with the highest number identified in the southeast region and an overall median price of $6500. Ninety percent of physicians were male and completed residencies in urology. Other specialties included obstetrics and gynecology, general surgery, family medicine and orthopedic surgery. Forty-two percent of urologists had completed infertility fellowships. Sixty percent of physicians utilized a microscope, and 4.7% of physicians explicitly stated they did not perform vasoepididymostomy even when indicated. Fifty two percent of clinics reported VR success rates as high as 100%, and 34% of clinics reported pregnancy outcomes. Twenty-five percent of clinics reported out-of-pocket VR pricing and 26% discussed possible complications. CONCLUSION: VR is a technically demanding cash-pay procedure being performed by physicians with a wide array of backgrounds and outcomes. Urologists should strive to lead by example and report their training, personal experiences, and expected outcomes to enable optimal medical decision making for each patient.

Self-Reported Physical Activity, QoL, Cardiac Function, and Cardiorespiratory Fitness in Women With HER2+ Breast Cancer.

Background: Women treated for breast cancer are at risk for worsening health-related quality of life (QoL), cardiac function, and cardiorespiratory fitness. Objectives: The aim of this study was to assess the associations of self-reported moderate to vigorous intensity physical activity (MVPA) during cancer treatment with concurrent measures of QoL and cardiac function and with post-treatment cardiorespiratory fitness in women with human epidermal growth factor receptor 2-positive breast cancer receiving sequential anthracyclines and trastuzumab. Methods: EMBRACE-MRI 1 (Evaluation of Myocardial Changes During Breast Adenocarcinoma Therapy to Detect Cardiotoxicity Earlier With MRI) study participants who completed questionnaires for MVPA (modified Godin Leisure Time Physical Activity Questionnaire) and QoL (EQ-5D-3L, Minnesota Living With Heart Failure Questionnaire) and cardiac imaging every 3 months during treatment and post-treatment cardiopulmonary exercise testing were included. Participants engaging in ≥90 minutes of MVPA each week were labeled "active." Generalized estimation equations and linear regression analyses were used to assess concurrent and post-treatment associations with MVPA and activity status, respectively. Results: Eighty-eight participants were included (mean age 51.4 ± 8.9 years). Mean MVPA minutes, QoL, and cardiac function (left ventricular ejection fraction, global longitudinal strain, E/A ratio, and E/e' ratio) worsened by 6 months into trastuzumab therapy. Higher MVPA (per 30 minutes) during treatment was associated with better concurrent overall (ß = -0.42) and physical (ß = -0.24) Minnesota Living With Heart Failure Questionnaire scores, EQ-5D-3L index (ß = 0.003), visual analogue scale score (ß = 0.43), diastolic function (E/A ratio; ß = 0.01), and global longitudinal strain (ß = 0.04) at each time point (P ≤ 0.01 for all). Greater cumulative MVPA over the treatment period was associated with higher post-treatment cardiorespiratory fitness (peak oxygen consumption; ß = 0.06 per 30 minutes; P < 0.001). Conclusions: Higher self-reported MVPA during treatment for human epidermal growth factor receptor 2-positive breast cancer was associated with better QoL and diastolic and systolic left ventricular function measures during treatment and better post-treatment cardiorespiratory fitness.

Exercise and Lifestyle Education program for Brazilians living with prediabetes and diabetes: A pilot randomized trial.

AIMS: To test the Diabetes College Brazil Study feasibility, the acceptability of study interventions and their preliminary effectiveness, and describe the study protocol modifications due to the COVID-19 pandemic. METHODS: Single-center, double-blinded pilot randomized trial with two parallel groups, Exercise and Lifestyle Education (ExLE; 12-week exercise and educational interventions) and Exercise (Ex; 12-week exercise intervention only) involving patients with prediabetes or diabetes. Feasibility (eligibility, recruitment, retention, completeness of variables measures and participation rates), acceptability (satisfaction), and preliminary effectiveness of interventions (variables: functional capacity, physical activity (PA), exercise self-efficacy, diabetes knowledge, health literacy, adherence to Mediterranean food pattern, glycated hemoglobin (HbA1c), anthropometric measures, cardiac autonomic control, depression, and quality of life (QofL)). RESULTS: Eligibility, recruitment, retention, participation in exercise sessions, and education classes rates were 17%, 93%,82%, 76%, and 71%, respectively. Missing data in the post-intervention assessment (PA, HbA1c, cardiac autonomic control, anthropometric measures, depression, and QofL) were mainly related to research procedure modifications. The interventions were highly acceptable, and most variables improved farther in the ExLE, with moderate effect sizes for PA, diabetes knowledge, health literacy, cardiac autonomic control, and QofL. CONCLUSIONS: The Diabetes College Brazil Study is feasible, and the ExLE may benefit Brazilians living with prediabetes and diabetes.

Research Quality and Impact of Cardiac Rehabilitation in Cancer Survivors: A Systematic Review and Meta-Analysis.

Background: Cardiac rehabilitation (CR) is endorsed to improve cardiovascular outcomes in cancer survivors. The quality of CR-based research in oncology has not been assessed. Objectives: The aim of this study was to evaluate the quality of reporting and evidence from CR-based intervention studies in oncology and to explore associations between intervention participation and outcomes. Methods: Systematic searches of 5 databases were conducted (January 2020) and updated (September 2021). Randomized and nonrandomized studies evaluating CR-based interventions in adult cancer survivors during and after treatment were eligible. Independent reviewers extracted data using 2 reporting guidelines (Template for Intervention Description and Replication and Consolidated Standards for Reporting Trials Harms extension), risk of bias (ROB) assessment tools (Cochrane ROB 2.0 and Cochrane Risk of Bias in Non-Randomized Studies of Interventions), and a combined inventory (Tool for the Assessment of Study Quality and reporting in Exercise). A meta-analysis was used to explore pre-intervention/post-intervention differences for commonly assessed outcomes. Results: Ten studies involving data from 685 survivors were included. The mean quality scores for intervention reporting (Template for Intervention Description and Replication) and harms (Consolidated Standards for Reporting Trials Harms extension) were 62% and 17%, respectively. There was moderate-to-high ROB across nonrandomized (Cochrane Risk of Bias in Non-Randomized Studies of Interventions score: 25%) and randomized (ROB 2.0 score: 50%) studies. The mean standardized cardiorespiratory fitness was higher (0.42; 95% CI: 0.27-0.57), fatigue was lower (-0.45; 95% CI: -0.55 to -0.34), and percent body fat (0.07; 95% CI: -0.23 to 0.38) was not different in survivors completing CR compared with those not completing CR. Conclusions: CR-based studies in oncology have low-to-moderate reporting quality and moderate-to-high ROB limiting interpretation, reproducibility, and translation of this evidence into practice.

Breast cancer survivors' physical activity and experiences while transitioning to a virtual cardiovascular rehabilitation program during a pandemic (COVID-19).

Breast cancer accounts for 25% of all cancers among Canadian females. Despite successes of decreased mortality, adverse treatment effects, such as cardiotoxicity, contribute to a sedentary lifestyle and decreased quality of life. Physical activity (PA) is a possible therapy for the late effects; however, COVID-19 restricted access to in-person cardiovascular rehabilitation (CR) programs. The purposes are as follows: (1) compare PA of breast cancer survivors' in-person CR to virtual CR following a transition during COVID-19 and (2) compare the PA of the pandemic cohort to a matched cohort who had completed the program in 2018/2019; (3) explore survivors' experiences of transitioning to and engaging in virtual CR. Mixed methods included analysis of CR PA data from a pandemic cohort (n = 18) and a 2018/2019 cohort (n = 18) and semi-structured focus group interviews with the pandemic cohort (n = 9) in the context of the PRECEDE-PROCEED model. After the transition, there were no significant differences in mean activity duration, frequency, and cumulative activity (expressed as MET-minutes) (p > 0.05). However, variation of PA duration doubled following the transition from in-person to virtual (p = 0.029), while for the 2018/2019 cohort, variation remained unchanged. Focus groups revealed that women valued their CR experiences pre-COVID-19 and had feelings of anxiety during the transition. Perceived factors affecting participation were environmental, personal, and behavioural. Recommendations for virtual programs were to increase comradery, technology, and professional guidance. PA experiences during a transition to virtual care prompted by a pandemic vary among breast cancer survivors. Targeting individualised strategies and exercise prescriptions are important for improving PA programs and patient outcomes.

Percepções dos Participantes de Reabilitação Cardíaca sobre seus Comportamentos em Saúde e Necessidades de Informação durante a Pandemia COVID-19 no Brasil / Perceptions of Cardiac Rehabilitation Participants Regarding their Health Behaviors and Information Needs during the COVID-19 Pandemic in Brazil

Resumo Fundamento A COVID-19 afetou como as pessoas recebem atendimento de saúde para várias doenças, inclusive doenças cardiovasculares. Objetivos Examinar as percepções dos participantes de reabilitação cardíaca (RC) sobre seus comportamentos em saúde e necessidades de informação durante a pandemia da COVID-19 no Brasil. Métodos Neste estudo transversal, um questionário de 27 itens elaborado pelos investigadores foi administrado online a participantes de dois programas de RC. As perguntas incluíam letramento em saúde (LS; usando a Brief Health Literacy Screening Tool - Breve ferramenta de triagem de letramento em saúde), uso de tecnologia, percepções antes e durante a pandemia da COVID-19, e necessidades de informações. Foram usados coeficiente de correlação de Pearson, testes t pareados e ANOVA, conforme apropriado. Um p <0,05 foi considerado estatisticamente significativo para todos os testes. Resultados No total, 159 (25,5%) participantes de RC responderam ao questionário. Desses, 89,9% tinham LS limitado ou marginal, e 96,2% relataram ter acesso à internet de casa. Os pacientes se preocupam principalmente com a saúde de sua família e própria, além de como o coronavírus é perigoso para sua saúde e como mudou seu estilo de vida. Os participantes perceberam que a qualidade de seus comportamentos em saúde diminuiu significativamente durante a pandemia. A pandemia também mudou as necessidades de informações dos participantes de RC, já que novas necessidades surgiram, tais como, controle de níveis de ansiedade, manter a motivação para levar uma vida saudável durante a pandemia, e como a COVID-19 pode afetar sua condição de saúde. Participantes com LS adequado perceberam significativamente a gravidade da doença e tinham significativamente mais acesso a informações do que os pacientes com LS limitado. Conclusões Nossos resultados destacaram o impacto da pandemia nas percepções dos participantes de RC em relação a seus comportamentos em saúde e necessidades de informação, que podem ser influenciados pelos níveis de LS.

Abstract Background COVID-19 has impacted how people receive health care for many conditions, including cardiovascular diseases. Objectives To examine perceptions of cardiac rehabilitation (CR) participants regarding their health behaviors and information needs during the COVID-19 pandemic in Brazil. Methods In this cross-sectional study, a 27-item questionnaire, developed by the investigators, was administered online to participants from two CR programs. Questions included health literacy (HL; using the Brief Health Literacy Screening Tool), technology use, perceptions before and during the COVID-19 pandemic, and information needs. Pearson correlation coefficients, paired t-tests, and ANOVA were used as appropriate. P < 0.05 was considered statistically significant for all tests. Results Overall, 159 (25.5%) CR participants answered the questionnaire. Of these, 89.9% had limited or marginal HL and 96.2% reported having internet access at home. Patients are mainly concerned about their family's health and their own, as well as how the coronavirus is dangerous to their health and how it has changed their lifestyle. Participants perceived that the quality of their health behaviors significantly decreased during the pandemic. The pandemic also changed information needs of CR participants as new needs emerged, such as the control of anxiety levels, staying motivated to live healthily during a pandemic, and how COVID-19 can impact their health condition. Participants with adequate HL significantly perceived the severity of the disease and having access to information significantly more than those with limited HL. Conclusions Our results highlighted the impact of the pandemic on CR participants' perceptions regarding their health behaviors and information needs, which can be influenced by HL levels.

Altered central and blood glutathione in Alzheimer's disease and mild cognitive impairment: a meta-analysis.

BACKGROUND: Increasing evidence implicates oxidative stress (OS) in Alzheimer disease (AD) and mild cognitive impairment (MCI). Depletion of the brain antioxidant glutathione (GSH) may be important in OS-mediated neurodegeneration, though studies of post-mortem brain GSH changes in AD have been inconclusive. Recent in vivo measurements of the brain and blood GSH may shed light on GSH changes earlier in the disease. AIM: To quantitatively review in vivo GSH in AD and MCI compared to healthy controls (HC) using meta-analyses. METHOD: Studies with in vivo brain or blood GSH levels in MCI or AD with a HC group were identified using MEDLINE, PsychInfo, and Embase (1947-June 2020). Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated for outcomes using random effects models. Outcome measures included brain GSH (Meshcher-Garwood Point Resolved Spectroscopy (MEGA-PRESS) versus non-MEGA-PRESS) and blood GSH (intracellular versus extracellular) in AD and MCI. The Q statistic and Egger's test were used to assess heterogeneity and risk of publication bias, respectively. RESULTS: For brain GSH, 4 AD (AD=135, HC=223) and 4 MCI (MCI=213, HC=211) studies were included. For blood GSH, 26 AD (AD=1203, HC=1135) and 7 MCI (MCI=434, HC=408) studies were included. Brain GSH overall did not differ in AD or MCI compared to HC; however, the subgroup of studies using MEGA-PRESS reported lower brain GSH in AD (SMD [95%CI] -1.45 [-1.83, -1.06], p<0.001) and MCI (-1.15 [-1.71, -0.59], z=4.0, p<0.001). AD had lower intracellular and extracellular blood GSH overall (-0.87 [-1. 30, -0.44], z=3.96, p<0.001). In a subgroup analysis, intracellular GSH was lower in MCI (-0.66 [-1.11, -0.21], p=0.025). Heterogeneity was observed throughout (I2 >85%) and not fully accounted by subgroup analysis. Egger's test indicated risk of publication bias. CONCLUSION: Blood intracellular GSH decrease is seen in MCI, while both intra- and extracellular decreases were seen in AD. Brain GSH is decreased in AD and MCI in subgroup analysis. Potential bias and heterogeneity suggest the need for measurement standardization and additional studies to explore sources of heterogeneity.

Evaluation of the Structure and Health Impacts of Exercise-Based Cardiac and Pulmonary Rehabilitation and Prehabilitation for Individuals With Cancer: A Systematic Review and Meta-Analysis.

Exercise-based, multimodal rehabilitation programming similar to that used in the existing models of cardiac or pulmonary rehabilitation or prehabilitation is a holistic potential solution to address the range of physical, psychological, and existential (e.g., as their diagnosis relates to potential death) stressors associated with a cancer diagnosis and subsequent treatment. The purpose of this study was to systematically evaluate the structure and format of any type of exercise-based, multimodal rehabilitation programs used in individuals with cancer and the evidence base for their real-world effectiveness on metrics of physical (e.g., cardiorespiratory fitness, blood pressure) and psychological (e.g., health-related quality of life) health. Very few of the 33 included exercise-based, multimodal rehabilitation programs employed intervention components, education topics, and program support staff that were multi-disciplinary or cancer-specific. In particular, a greater emphasis on nutrition care, and the evaluation and management of psychosocial distress and CVD risk factors, with cancer-specific adaptations, would broaden and maximize the holistic health benefits of exercise-based rehabilitation. Despite these opportunities for improvement, exercise-based, multimodal rehabilitation programs utilized under real-world settings in individuals with cancer produced clinically meaningful and large effect sizes for cardiorespiratory fitness (VO2peak, ±2.9 mL/kg/min, 95% CI = 2.6 to 3.3) and 6-minute walk distance (+47 meters, 95% CI = 23 to 71), and medium effect sizes for various measures of cancer-specific, health-related quality of life. However, there were no changes to blood pressure, body mass index, or lung function. Overall, these findings suggest that exercise-based, multimodal rehabilitation is a real-world therapy that improves physical and psychological health among individuals with cancer, but the holistic health benefits of this intervention would likely be enhanced by addressing nutrition, psychosocial concerns, and risk factor management through education and counselling with consideration of the needs of an individual with cancer.

A Critical Review on New Approaches for Chronic Disease Prevention in Brazil and Canada: From Wholistic Dietary Guidelines to Physical Activity Security.

In light of new evidence on the prevention of chronic diseases and the elevated rates of overweight and obesity in Brazil and Canada, this critical review aims to interpret and synthesize current aspects regarding dietary and physical activity initiatives in both countries and make future recommendations. The pioneering work presented in the last Brazilian dietary guidelines has been called a model that can be applied globally, given its conceptualization of healthy eating that translates easily to practical guidance. The new Canadian Food Guide has incorporated similar aspects, also putting the country as a leader in dietary guidance. With these new recommendations, citizens in both Brazil and Canada have access to impactful evidence-informed nutritional guidelines. Both documents propose eating patterns that focus not only on health benefits, such as chronic disease prevention, but also incorporate well-being concerning cultural, economic, sociodemographic, biological, and ecological dimensions. A similar approach is required for physical activity to allow individuals to have attainable health and life goals and thereby fully enjoy their lives, regardless of geographical location, health status, and socioeconomic condition, a concept recently described as physical activity security. The wholistic dietary guidelines from both countries represent a change in paradigm in public health. Likewise, national evidence-based policies are warranted to reduce disparities in physical activity, allowing healthier and more active lifestyles for everyone.

Patient education program for Brazilians living with diabetes and prediabetes: findings from a development study.

BACKGROUND: Globally, the incidence of diabetes is increasing and strategies to reach a comprehensive approach of care are needed, including education in self-management. This is particularly true in low and middle-income countries where the number of people living with diabetes is higher than in the high-income ones. This article describes the development of a structured patient education program for Brazilians living with diabetes or prediabetes. METHODS: These steps were undertaken: 1) a 4-phase needs assessment (literature search of local diabetes guidelines, environmental scan, evaluation of information needs of patients identified by diabetes experts, and patient focus groups); and, 2) the translation and cultural adaptation of the patient guide (preparation, translation, back-translation, back-translation review, harmonization, and proofreading). RESULTS: Four of the seven guidelines identified include educational aspects of diabetes management. No structured education program was reported from the environmental scan. Regarding the information needs, 15 diabetes experts identified their patients' needs, who referred that they have high information needs for topics related to their health condition. Finally, results from six patient focus groups were clustered into six themes (self-management, physical activity, eating habits, diabetes medication, psychosocial being, and sleep), all embedded into the new education program. Constructive theory, adult learning principles, and the Health Action Process Approach model were used in program development and will be used in delivery. The developed program consists of 18 educational sessions strategically mapped and sequenced to support the program learning outcomes and a patient guide with 17 chapters organized into five sections, matched with weekly lectures. CONCLUSIONS: This program is a sequential and theoretical strategic intervention that can reach programs in Brazil to support diabetes and prediabetes patient education.

Chronic Scrotal Content Pain: a Review of the Literature and Management Schemes.

PURPOSE OF REVIEW: Chronic scrotal content pain (CSCP) is a complex condition with multiple etiologies that requires a thorough understanding of its pathophysiology, workup, and treatment options. We performed a comprehensive and contemporary review to augment our current understanding of CSCP. RECENT FINDINGS: We discuss new advances in CSCP-specific pain questionnaires, modern studies of microscopic spermatic cord denervation and its variations, and novel techniques including electric nerve stimulation and cryoablation in addition to randomized control trials with significant negative findings. We also present literature focusing on the prevention of CSCP secondary to surgical iatrogenic causes. The constantly evolving literature of CSCP has led to the significant evolution in its diagnosis and treatment, from oral medications to salvage options after microscopic spermatic cord denervation. With each advance, we come closer to developing a more thorough, evidence-based algorithm to guide urologists in treatment of CSCP.

A Retrospective Comparison of Fitness and Exercise Progression in Patients With Coronary and Peripheral Artery Disease in Cardiac Rehabilitation.

BACKGROUND: Cardiac rehabilitation (CR) is recommended for patients with coronary (CAD) and peripheral (PAD) artery disease. However, no study has compared changes in cardiorespiratory fitness (VO2peak) or exercise prescription progression among PAD, CAD, and concomitant PAD and CAD (BOTH). The objectives of this study were to 1) compare change in VO2peak among patients with PAD, CAD, and BOTH, and 2) examine progression in exercise prescription parameters in a comprehensive 6-month cardiac rehabilitation (CR) program. METHODS: A retrospective analysis of patient data recorded from 2006 to 2017 from a large urban hospital was conducted. Patients with PAD (n = 63) and BOTH (n = 164) were included in the analyses. Patients with CAD (n = 63) were matched to PAD by sex (36.5% female), age (69 years), smoking status, diabetes, and year in program. RESULTS: There were significant improvements in VO2peak from baseline to 6 months in all groups (CAD +2.7 ± 3.4 mL⋅kg-1⋅min-1, PAD +2.4 ± 3.8 mL⋅kg-1⋅min-1, BOTH +1.8 ± 3.1 mL⋅kg-1⋅min-1; all P < 0.001). Between-group differences were significant between PAD and CAD as well as between CAD and BOTH (P = 0.001). Walking distance, duration, and pace increased for all groups over 6 months (P < 0.001), with a significant difference in pace between CAD and BOTH (P = 0.006). CONCLUSIONS: Patients with PAD, CAD, and BOTH had significant improvements in VO2peak following a 6-month CR program. However, despite similar prescribed walking distance and duration, improvements in VO2peak were mitigated in PAD and BOTH compared with CAD. These results support benefits of CR for patients diagnosed with PAD, but alternate exercise strategies should be explored for patients with PAD.

Cardiac Rehabilitation Component Attendance and Impact of Intervening Clinical Events, as Well as Disease Severity and Risk Factor Burden.

PURPOSE: To examine: (1) the rate of clinical events precluding cardiac rehabilitation (CR) continuation, (2) CR attendance by component in those without events, and (3) the association between disease severity (eg, tobacco use, diabetes, and depression) and component attendance (eg, exercise, diet, stress management, and tobacco cessation). METHODS: Retrospective analysis of electronic records of the CR program in London, Ontario, from 1999 to 2017. Patients in the supervised program are offered exercise sessions 2 times/wk with a minimum of 48 prescribed sessions tailored to patient need. Patients attending ≥1 session without major factors that would limit their exercise ability were included. Intervening events were recorded, as was component attendance. RESULTS: Of 5508 enrolled, supervised patients, 3696 did not have a condition that could preclude exercise. Of those enrolled, one-sixth (n = 912) had an intervening event; these patients were less likely to work, more likely to have medical risk factors, had more severe angina and depression, and lower functional capacity. The remaining cohort attended a mean of 26.5 ± 21.3 sessions overall (median = 27; 19% attending ≥48 sessions), including 20.5 ± 17.4 exercise sessions (median = 21). After exercise, the most common components attended were individual dietary and psychological counseling. Patients with more severe angina and depressive symptoms as well as tobacco users attended significantly fewer total sessions, but more of some specific components. CONCLUSIONS: In one-sixth of patients, CR attendance and completion are impacted by clinical factors beyond their control. Many patients are taking advantage of components specific to their risk factors, buttressing the value of individually tailored, menu-based programming.

CaRE @ Home: Pilot Study of an Online Multidimensional Cancer Rehabilitation and Exercise Program for Cancer Survivors.

BACKGROUND: Although facility-based cancer rehabilitation and exercise programs exist, patients are often unable to attend due to distance, cost, and other competing obligations. There is a need for scalable remote interventions that can reach and serve a larger population. METHODS: We conducted a mixed methods pilot study to assess the feasibility, acceptability and impact of CaRE@Home: an 8-week online multidimensional cancer rehabilitation and exercise program. Feasibility and acceptability data were captured by attendance and adherence metrics and through qualitative interviews. Preliminary estimates of the effects of CaRE@Home on patient-reported and physically measured outcomes were calculated. RESULTS: A total of n = 35 participated in the study. Recruitment (64%), retention (83%), and adherence (80%) rates, along with qualitative findings, support the feasibility of the CaRE@Home intervention. Acceptability was also high, and participants provided useful feedback for program improvements. Disability (WHODAS 2.0) scores significantly decreased from baseline (T1) to immediately post-intervention (T2) and three months post-intervention (T3) (p = 0.03 and p = 0.008). Physical activity (GSLTPAQ) levels significantly increased for both Total LSI (p = 0.007 and p = 0.0002) and moderate to strenuous LSI (p = 0.003 and p = 0.002) from baseline to T2 and T3. Work productivity (iPCQ) increased from T1 to T3 (p = 0.026). There was a significant increase in six minute walk distance from baseline to T2 and T3 (p < 0.001 and p = 0.010) and in grip strength from baseline to T2 and T3 (p = 0.003 and p < 0.001). CONCLUSIONS: Results indicate that the CaRE@Home program is a feasible and acceptable cancer rehabilitation program that may help cancer survivors regain functional ability and decrease disability. In order to confirm these findings, a controlled trial is required.

Comprehensive Cardiac Rehabilitation Effectiveness in a Middle-Income Setting: A RANDOMIZED CONTROLLED TRIAL.

PURPOSE: The impact of comprehensive cardiac rehabilitation (CCR) in Latin America is not well known. Herein, the pre-specified tertiary outcomes of a cardiac rehabilitation (CR) trial are reported: disease-related knowledge, depressive symptoms, and heart-health behaviors (exercise, diet, and smoking). METHODS: This was a single-blinded, single-center (Brazil) randomized trial with three parallel arms: CCR (exercise + education) versus exercise-only CR versus wait-list control. Eligible patients were randomized in blocks of four with 1:1:1 concealed allocation. The CR program was 6 mo long. Participants randomized to exercise-only CR received 36 exercise classes; the CCR group also received 24 educational sessions, including a workbook. All outcomes were assessed at pre-test and 6-mo later (blinded). Analysis of covariance was performed by intention-to-treat (ITT) and per-protocol (PP). RESULTS: A total of 115 (89%) patients were randomized; 93 (81%) were retained. There were significant improvements in knowledge with CCR (ITT [51.2 ± 11.9 pre and 60.8 ± 13.2 post] and PP; P < .01), with significantly greater knowledge with CCR versus control (ITT mean difference [MD] = 9.5, 95% CI, 2.3-16.8) and CCR vs exercise-only CR at post-test (ITT MD = 6.8, 95% CI, 0.3-14.0). There were also significant improvements in self-reported exercise with CCR (ITT [13.7 ± 15.8 pre and 32.1 ± 2 5.7 post] and PP; P < .001), with significantly greater exercise with CCR versus control at post-test (ITT MD = 7.6, 95% CI, 3.8-11.4). Also, there were significant improvements in diet with CCR (PP: 3.4 ± 7.5 pre and 8.0 ± 7.0 post; P < .05). CONCLUSIONS: In this first-ever randomized trial of CR for coronary artery disease in Latin America, the benefits of CCR have been supported.

Effectiveness of an Education Intervention Among Cardiac Rehabilitation Patients in Canada: A Multi-Site Study.

BACKGROUND: Although patient education is considered a core component of cardiac rehabilitation (CR) programs, to our knowledge, no educational program designed for CR has been standardized in Canada. This absence of standardization may be due to a lack of reliable resources to educate these patients. The objective of this study was to assess the effectiveness of an education intervention in improving knowledge and health behaviours among CR patients in 3 sites in Canada. METHODS: CR patients were exposed to an evidence- and theoretically based comprehensive education intervention. Patients completed surveys assessing knowledge, physical activity, food intake, self-efficacy, and health literacy. All outcomes were assessed pre- and post-CR. Paired t tests were used to investigate variable changes between pre- and post-CR, Pearson correlation coefficients were used to determine the association between knowledge and behaviours, and linear regression models were computed to investigate differences in overall post-CR knowledge based on participant characteristics. RESULTS: A total of 252 patients consented to participate, of whom 158 (63.0%) completed post-CR assessments. There was a significant improvement in patients' overall knowledge pre- to post-CR, as well as in exercise, food intake, and self-efficacy (P < 0.05). Results showed a significant positive correlation between post-CR knowledge and food intake (r = 0.203; P = 0.01), self-efficacy (r = 0.201; P = 0.01), and health literacy (r = 0.241; P = 0.002). Education level (unstandardized beta = -2.511; P = 0.04) and pre-CR knowledge (unstandardized beta = 0.433; P < 0.001) were influential in changing post-CR knowledge. CONCLUSION: In this first-ever multi-site study focusing on patient education for CR patients in Canada, the benefits of an education intervention have been supported.

CONTEXTE: Bien que l'éducation du patient soit considérée comme un élément essentiel des programmes de réadaptation cardiaque (RC), il n'existe, à notre connaissance, aucun programme éducatif standardisé en RC au Canada. Cette absence de standardisation peut être attribuable à un manque de ressources fiables en matière d'éducation des patients. Cette étude visait à évaluer l'efficacité réelle d'une intervention éducative au regard de l'amélioration des connaissances et des comportements touchant la santé chez des patients en RC dans trois établissements au Canada. MÉTHODOLOGIE: Une intervention éducative globale fondée sur des données probantes et théoriques a été menée auprès de patients en RC. Les patients ont répondu à des questionnaires d'évaluation des connaissances, de l'activité physique, de l'apport alimentaire, de l'autoefficacité et de la littératie en matière de santé. Tous les résultats ont été évalués avant et après la RC. Des tests t pour échantillons appariés ont été utilisés pour étudier les changements touchant les variables évaluées avant et après la RC, des coefficients de corrélation de Pearson ont servi à déterminer l'association entre les connaissances et les comportements, et des modèles de régression linéaire ont été calculés pour étudier les différences dans les connaissances globales après la RC en fonction des caractéristiques des participants. RÉSULTATS: Au total, 252 patients ont accepté de participer; de ce nombre, 158 (63,0 %) ont pris part aux évaluations postérieures à la RC. Les connaissances globales des patients se sont améliorées de façon significative d'avant à après la RC, tout comme l'activité physique, l'apport alimentaire et l'autoefficacité (p < 0,05). Les résultats ont montré une corrélation positive significative entre les connaissances et l'apport alimentaire (r = 0,203; p = 0,01), l'autoefficacité (r = 0,201; p = 0,01) et la littératie en matière de santé (r = 0,241; p = 0,002) après la RC. Le niveau d'éducation (B = -2,511; p = 0,04) et les connaissances avant la RC (B = 0,433; p < 0,001) ont influé sur les changements touchant les connaissances après la RC. CONCLUSION: Cette toute première étude multicentrique axée sur l'éducation des patients en RC au Canada a permis de confirmer les avantages d'une intervention éducative.

Endostatin as a Mediator Between Endothelial Function and Cognitive Performance in Those at Risk for Vascular Cognitive Impairment.

BACKGROUND: Patients with coronary artery disease have an increased risk for developing vascular cognitive impairment. Endothelial function is often diminished and has been associated with lower cognitive performance in these patients. The link between endothelial function and cognition in coronary artery disease is not fully understood. Angiogenesis may play a role in mediating the association between endothelial function and cognition since angiogenic processes rely heavily on the endothelium. OBJECTIVE: The aim of this study was to determine if markers of angiogenesis mediate the relationship between endothelial function and cognition in coronary artery disease patients. METHODS: In 50 participants with coronary artery disease, endothelial function was assessed using peripheral arterial tonometry. Vascular endothelial growth factor (pro-angiogenic) and endostatin (anti-angiogenic) were measured in peripheral serum samples. Cognition was assessed using the Montreal Cognitive Assessment. A mediation analysis, using a bias corrected inferential bootstrapping method with 10,000 permutations, was used to determine if vascular endothelial growth factor or endostatin mediated an association between peripheral arterial tonometry measures and cognitive performance on the Montreal Cognitive Assessment. RESULTS: Endostatin, but not vascular endothelial growth factor, mediated a relationship between endothelial function and cognitive performance when controlling for total years of education, body mass index, coronary artery bypass graft, stent, diabetes, and diuretic use. This analysis was also significant when delayed recall was substituted for the overall score on the Montreal Cognitive Assessment. CONCLUSION: These results suggest that endostatin mediates an association between endothelial function and cognitive performance in coronary artery disease.
