Dietary Micronutrient Intake of Participants in a "Partners Together in Health" Cardiac Rehabilitation Intervention

Effectiveness and reporting of nutrition interventions in cardiac rehabilitation programmes: a systematic review

AIMS

Dietary modification is essential for the secondary prevention of cardiovascular disease. However, there are limited published evidence syntheses to guide practice in the cardiac rehabilitation (CR) setting. This systematic review's objective was to assess effectiveness and reporting of nutrition interventions to optimize dietary intake in adults attending CR.

METHODS AND RESULTS

Randomized controlled trials (RCTs) of nutrition interventions within CR were eligible for inclusion and had to have measured change in dietary intake. MEDLINE, Embase, Emcare, PsycINFO, CINAHL, Scopus, and The Cochrane Library were searched from 2000 to June 2020, limited to publications in English. Evidence from included RCTs was synthesized descriptively. The risk of bias was assessed using the Cochrane Risk of Bias 2 tool. This review is registered on PROSPERO; CRD42020188723. Of 13 048 unique articles identified, 11 were eligible. Randomized controlled trials were conducted in 10 different countries, included 1542 participants, and evaluated 29 distinct dietary intake outcomes. Five studies reported statistically significant changes in diet across 13 outcomes. Most nutrition interventions were not reported in a manner that allowed replication in clinical practice or future research.

CONCLUSION

There is a gap in research testing high-quality nutrition interventions in CR settings. Findings should be interpreted in the light of limitations, given the overall body of evidence was heterogenous across outcomes and study quality; 6 of 11 studies were conducted more than 10 years old. Future research should investigate strategies to optimize and maintain nutrition improvements for patients attending CR.

A Teaching Kitchen Program Improves Employee Micronutrient and Healthy Dietary Consumption

Objective

To measure changes in micronutrient adequacy and diet quality in healthcare and university employees who underwent a 10-week teaching kitchen program.

Methods

Thirty-eight healthcare and university employees participated in a 10-week teaching kitchen program. Twenty-seven completed self-administered, 24-hour dietary recalls to measure dietary intake at baseline and 3-months. Micronutrient adequacy and diet quality was assessed using Dietary Reference Intakes (DRIs) and the Healthy Eating Index (HEI).

Results

Seventy percent of participants were classified as low or moderate micronutrient adequacy at baseline. The proportion of participants with high micronutrient adequacy increased from 30% to 48% at 3-month follow-up. Total HEI and most HEI components increased at follow-up; with a statistically significant increase in seafood/plant protein score (P = .007).

Conclusions and Implications for Practice

Our results suggest an inadequacy in micronutrient intake in university and healthcare employees and that teaching kitchens may help improve micronutrient adequacy and diet quality.

Retinoic acid regulates pyruvate dehydrogenase kinase 4 (Pdk4) to modulate fuel utilization in the adult heart: Insights from wild-type and β-carotene 9',10' oxygenase knockout mice

Regulation of the pyruvate dehydrogenase (PDH) complex by the pyruvate dehydrogenase kinase PDK4 enables the heart to respond to fluctuations in energy demands and substrate availability. Retinoic acid, the transcriptionally active form of vitamin A, is known to be involved in the regulation of cardiac function and growth during embryogenesis as well as under pathological conditions. Whether retinoic acid also maintains cardiac health under physiological conditions is unknown. However, vitamin A status and intake of its carotenoid precursor β-carotene have been linked to the prevention of heart diseases. Here, we provide in vitro and in vivo evidence that retinoic acid regulates cardiac Pdk4 expression and thus PDH activity. Furthermore, we show that mice lacking β-carotene 9',10'-oxygenase (BCO2), the only enzyme of the adult heart that cleaves β-carotene to generate retinoids (vitamin A and its derivatives), displayed cardiac retinoic acid insufficiency and impaired metabolic flexibility linked to a compromised PDK4/PDH pathway. These findings provide novel insights into the functions of retinoic acid in regulating energy metabolism in adult tissues, especially the heart.

Nutrition Intervention in Cardiac Rehabilitation: A REVIEW OF THE LITERATURE AND STRATEGIES FOR THE FUTURE

OBJECTIVE

Despite guideline consensus that quality of nutrition affects most modifiable cardiovascular disease risk factors, the implementation of dietary interventions varies considerably in cardiac rehabilitation (CR) programs. The purpose of this review is to highlight the current existing literature and provide recommendations on best practices for nutrition interventions and future research that support secondary prevention outcomes.

REVIEW METHODS

The review examines original investigations, systematic reviews, and guidelines regarding nutrition intervention in CR.

SUMMARY

Nutrition intervention in CR plays an integral role in the success of patients; however, the literature is limited and standardization of practice is in its infancy. The role of a qualified registered dietician nutritionist, standardization of dietary assessments, individualized and intensive nutrition interventions, and application of specific behavior change techniques are central components in improving diet in CR. This review provides an overview of the evidence-based cardioprotective diets, nutritional interventions and behavioral strategies in CR, and explores areas for best practices and opportunities for innovation in the delivery of nutrition intervention in CR.

Early cardiac rehabilitation: could it improve functional outcomes and reduce length of stay and sanitary costs in patients aged 75 years or older? A retrospective case-control study

BACKGROUND

Cardiac rehabilitation (CR) is considered as a cornerstone in improving physical function in older people after cardiac procedures; however, its effects in patients aged more than 75 years are still debated.

AIMS

To assess the effectiveness of early CR in improving functional outcomes and reducing the length of stay (LOS) and sanitary costs in patients aged ≥ 75 years.

METHODS

We retrospectively analysed data from medical records of patients aged ≥ 75 years performed CR after cardiac procedures. Patients were divided into two groups according to the median timing lasting from the cardiac procedure and CR start: 'early rehabilitation' (< 8 days) and 'delayed rehabilitation' (≥ 8 days). Six-minutes walking test (6MWT), left ventricular ejection fraction (LVEF), LOS, and sanitary costs were assessed.

RESULTS

The 160 patients (mean aged 79.18 ± 3.13 years) included were divided into two groups: 'early rehabilitation' (n = 80) and 'delayed rehabilitation' (n = 80). Both groups showed a significant improvement (p < 0.0001) in 6MWT and LVEF but there were no differences between groups in all clinical outcomes. On the other hand, the 'early rehabilitation' group showed significantly lower LOS (25.8 ± 5.3 vs 34.1 ± 10.8 days; p < 0.0001) and sanitary costs (22,282.08 ± 3242.68 euros vs. 44,954.03 ± 22,160.11 euros; p < 0.0001).

DISCUSSION

Beginning CR in the first week seems to be effective in improving physical performance after cardiac procedures in patients aged ≥ 75 years, reducing LOS and sanitary costs.

CONCLUSIONS

Our findings suggest that early CR could be performed with positive effects on functional outcomes, leading to a reduction in LOS and sanitary costs in elderly.

Fruits and Vegetables in the Management of Underlying Conditions for COVID-19 High-Risk Groups

SARS-CoV-2 or COVID-19 is a novel coronavirus, which is the cause of the current pandemic with 107,411,561 infections and 2,351,195 death worldwide so far. There are multiple symptoms that are linked with the infection of COVID-19 such as coughing, shortness of breath, congestion together with fatigue, fever, loss of taste or smell, headaches, diarrhea, vomiting, and loss of appetite. The lack of or early stage of development of a cure for COVID-19 illness, there is need for insuring the best possible position of health to be able to fight the virus naturally through a robust immune system to limit severe complication. In this article, we have discussed the role of fruits and vegetables consumption to boost the immune system and major emphasis has been given to high risk group. We have taken into consideration a number of underlying conditions such as people with cardiovascular diseases, obesity, diabetes, chronic obstructive pulmonary disease, chronic kidney disease, hemoglobin disorder such as sickle cell disease, weakened immune system due to organ transplant. Furthermore, factors to improve the immune system, risks associated with quarantine and lifestyle and food handling during COVID-19 has been discussed.
