Dietitian Services Are Associated with Improved Patient Outcomes and the MEDFICTS Dietary Assessment Questionnaire Is a Suitable Outcome Measure in Cardiac Rehabilitation

The Role of Dietary Education in Cardiac Rehabilitation

Cardiovascular disease remains a leading cause of death globally; however, most cases could be prevented by addressing modifiable risk factors, such as unhealthy lifestyle factors, including diet. These aspects are also crucial in secondary prevention. Cardiac rehabilitation programs are vital in improving cardiovascular outcomes, and apart from recommended pharmacotherapy, they focus on lifestyle modifications, including exercise, a healthy diet, and smoking cessation. The aim of this review was to summarize the evidence on the role of dietary education in cardiac rehabilitation programs. The available data show that nutritional recommendations play an important role in cardiac rehabilitation programs, with the Mediterranean diet being widely recommended for its cardiovascular benefits. Adherence to dietary recommendations in the course of cardiac rehabilitation has been linked to improved metabolic and cardiovascular outcomes; however, further studies with long-term follow-up are needed. Moreover, while challenges in following dietary recommendations exist, individualized care and support are essential for successful outcomes in cardiac rehabilitation programs. Including dietary education is an important part of cardiac rehabilitation after myocardial infarction; however, more studies are needed to investigate the role of individualized dietary support and personalized education in cardiac rehabilitation.

Challenges and benefits of using the HeartDiet food frequency questionnaire in cardiac rehabilitation practice

BACKGROUND AND AIMS

A heart-healthy diet is an important component of secondary prevention in ischemic heart disease. The Danish Health Authority recommends using the validated 19-item food frequency questionnaire HeartDiet in cardiac rehabilitation practice to assess patients' need for dietary interventions, and HeartDiet has been included in national electronic patient-reported outcome instruments for cardiac rehabilitation. This study aims to evaluate challenges and benefits of its use. The objectives are to: 1) describe HeartDiet responses of patients with ischemic heart disease and discuss HeartDiet's suitability as a screening tool, 2) discuss whether an abridged version should replace HeartDiet.

METHODS AND RESULTS

A cross-sectional study using data from a national feasibility test. HeartDiet was sent electronically to 223 patients with ischemic heart disease prior to cardiac rehabilitation. Data were summarised with descriptive statistics, and Spearman's rank correlations, explorative factor analysis, and Cohen's kappa coefficient were used to derive and evaluate abridged versions. The response rate was 68 % (n = 151). Evaluated with HeartDiet, no respondents had a heart-healthy diet. There was substantial agreement between HeartDiet and an abridged 9-item version (kappa = 0.6926 for Fat Score, 0.6625 for FishFruitVegetable Score), but the abridged version omits information on milk products, wholegrain, nuts, and sugary snacks.

CONCLUSION

With the predefined cut-offs, HeartDiet's suitability as a screening tool to assess needs for dietary interventions was limited, since no respondents were categorised as having a heart-healthy diet. An abridged version can replace HeartDiet, but the tool's educational potential will be compromised, since important items will be omitted.

Provision of dietary education in UK-based cardiac rehabilitation: a cross-sectional survey conducted in conjunction with the British Association for Cardiovascular Prevention and Rehabilitation

Dietary education is a core component of cardiac rehabilitation (CR). It is unknown how or what dietary education is delivered across the UK. We aimed to characterise practitioners who deliver dietary education in UK CR and determine the format and content of the education sessions. A fifty-four-item survey was approved by the British Association for Cardiovascular Prevention and Rehabilitation (BACPR) committee and circulated between July and October 2021 via two emails to the BACPR mailing list and on social media. Practitioners providing dietary education within CR programmes were eligible to respond. Survey questions encompassed: practitioner job title and qualifications, resources, and the format, content and individual tailoring of diet education. Forty-nine different centres responded. Nurses (65·1 %) and dietitians (55·3 %) frequently provided dietary education. Practitioners had no nutrition-related qualifications in 46·9 % of services. Most services used credible resources to support their education, and 24·5 % used BACPR core competencies. CR programmes were mostly community based (40·8 %), lasting 8 weeks (range: 2-25) and included two (range: 1-7) diet sessions. Dietary history was assessed at the start (79·6 %) and followed up (83·7 %) by most centres; barriers to completing assessment were insufficient time, staffing or other priorities. Services mainly focused on the Mediterranean diet while topics such as malnutrition and protein intake were lower priority topics. Service improvement should focus on increasing qualifications of practitioners, standardisation of dietary assessment and improvement in protein and malnutrition screening and assessment.

Alterations in gut microbiota caused by major depressive disorder or a low FODMAP diet and where they overlap

Beneficial changes in microbiota observed in individuals with a major depressive disorder (MDD) may be initiated with a low fermentable oligosaccharide, disaccharide, monosaccharide, and polyol (FODMAP) elimination diet. Academic Search Ultimate, APA PsychINFO, Cochrane Library, MEDLINE, Scopus and Web of Science were searched for original research documenting differences in microbiota in MDD or changes with a low FODMAP diet in adults (age 18 years +). Studies with fecal microbiota, 16 s RNA sequencing and QIIME pipelines were included. Studies using antibiotics, probiotics, and medications such as antidepressants were excluded. Additionally, studies based on a single gender were excluded as gender impacts microbiota changes in MDD. Four studies addressed differences in microbiota with MDD and another four assessed shifts occurring with a low FODMAP diet. The abundance of Bacteroidetes, Bacteroidaceae and Bacteroides were lower in individuals with MDD but increased with a low FODMAP diet. Abundance of Ruminoccaceae was lower and Bilophila was higher with both a low FODMAP diet and MDD. These results provide preliminary evidence that a low FODMAP diet might drive changes in microbiota that also benefit people with MDD. Further research to assess whether a low FODMAP diet can treat MDD through modification of targeted microbiota is warranted.

Time-Restricted Eating: A Novel Dietary Strategy for Cardiac Rehabilitation

Cardiac rehabilitation (CR) is a multimodal program considered to be the standard of care for secondary prevention of cardiovascular disease (CVD). The primary goals of CR are managing CVD risk factors and improving quality of life. Exercise is the cornerstone, but nutrition education delivered by registered dietitians (RDs) is a core component of CR. Yet patient constraints to adherence to dietary change and limited availability of RDs represent major barriers to the success of completion of nutrition intervention during CR. Therefore, nutritional strategies that reduce CVD risk factors, barriers to adherence, and have capacity for broad dissemination are warranted within CR programs. In this review, we propose time-restricted eating (TRE) as a nutrition strategy to improve the outcomes of CR by drawing on parallels to CVD in other populations and describe the available preliminary data on the efficacy of TRE for CVD. TRE is a dietary strategy that involves alternating periods of fasting and consumption of calories each day. We outline the feasibility, safety, and beneficial cardiometabolic impact of TRE from TRE research in other populations. We also discuss the potential for synergistic benefits of exercise when combined with TRE. Although there is currently limited research on TRE within CR programs, we highlight CR as a unique clinical setting where TRE could play a role in secondary prevention of CVD. Overall, we outline the potential of TRE as a promising nutrition strategy to enhance the benefits of CR.

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.

Depression, Is It Treatable in Adults Utilising Dietary Interventions? A Systematic Review of Randomised Controlled Trials

This systematic literature review examined whole food or whole diet interventions to treat depression. The inclusion criteria encompassed adults, depression, a recognized depression scale and a whole food or diet intervention. APA PsychINFO, CINAHL, the Cochrance Central Register of Controlled Trails, MEDLINE and Scopus were searched for original research addressing diet as a treatment for depression in adult populations. The quality of the study was assessed using the Academy of Nutrition and Dietetics Quality Criteria Checklist. Seven studies; with 49,156 participants; met the eligibility criteria. All these studies found positive outcomes with depression levels decreasing after dietary intervention. The calculated effect size varied from small (Cohen’s d = 0.32) to very large (Cohen’s d = 1.82). The inconsistent nature of the studies limited the synthesis of the data. Recommendations are provided to enhance future study design and measurement outcomes. Overall, the findings show a positive result for diets that promote an increased intake of fresh produce, wholegrains, low-fat dairy and lean protein sources, while also decreasing the intake of processed and high-fat foods. No funding was provided for this review. The protocol for this review is registered with PROSPERO (CRD42020210426).

Physicians' Knowledge of Clinical Nutrition Discipline in Riyadh Saudi Arabia

Background: Nutrition plays a major role in the prevention and management of diet-related disease. With the absence of clinical nutrition dietitians, physicians are considered responsible for prescribing nutritional support. Identifying weaknesses in nutritional knowledge among Saudi physicians may provide guidance to improve their nutritional knowledge. Methods: A cross-sectional study that used an anonymous electronic questionnaire to investigate physicians’ knowledge of the clinical nutrition discipline. In addition to demographics, the questionnaire consisted of 15 questions covering six areas in the clinical nutrition discipline (macro- and micronutrients, nutrition and chronic diseases, nutrition and metabolic diseases, nutrition care process, nutrition support therapy, and research). For continuous variables, independent t-tests and one-way ANOVA were used. Results: A total of 332 had completed the questionnaire and were included in the study. Most of the physicians were Saudi (87%), male (73.5%), aged between 26 and 35 years (63.3%), and without health problems (56.3%). The mean score of the physicians’ knowledge was 5.3 ± 1.97 out of 15. Physicians who reported that they received some sort of nutritional training or course (M = 5.57, SD = 2.08) scored significantly more than physicians who did not (M = 5.10, SD = 1.86); t(330) = −2.174, p = 0.30. Conclusions: Nutrition should be reinforced as an important component of continuing medical education. There is a need for hiring more dietitians in health care settings in Saudi Arabia as an integral part of a multidisciplinary team delivering medical care services.

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.

Dietary measures among patients with coronary heart disease in Europe. ESC EORP Euroaspire V

OBJECTIVE

Assess the dietary recommendations provided to patients hospitalized for a coronary heart disease (CHD) event.

DESIGN

Cross-sectional, multicentre observational study (ESC EORP Euroaspire V).

METHODS

8261 participants (25.8% women, 9.3% aged<50 years) from 27 countries, 6 to 24 months after hospitalization for a CHD event were included. Participants were asked if they had been advised to reduce salt, fat or sugar intake, change type of fat consumed, and increase consumption of plant stanols/sterols, fruit & vegetables, fish and oily fish. Self-reported changes were recorded.

RESULTS

Advice to reduce energy intake, salt, fat and sugar was provided to 64.5% [range: 9.2-90.5], 73.2% [38.6-95.2], 77.3% [42.3-95.6] and 67.0% [39.4-93.3] of patients, respectively. Advice to change fat type, increase consumption of plant stanols/sterols, fruit & vegetables, fish and oily fish was provided to 68.3% [33.7-92.3], 36.7% [0.6-75.2], 73.2% [39.2-93.6], 66.5% [8.0-90.8] and 53.5% [3.7-83.3] of patients, respectively. Advices were more frequently provided to patients aged 50 to 69, with a high educational level, or obesity. One-eighth [0-55.0] of patients reported having consulted a dietician. Reductions in energy intake, salt, fat and sugar were reported by 57.7% [4.9-81.0], 69.9% [32.1-85.9], 71.8% [40.4-88.4] and 61.2% [29.0-84.0] of patients, respectively. Changes in fat type and increased consumption of plant stanols/sterols, fruit & vegetables, fish and oily fish were reported by 60.9% [4.9-81.0], 25.8% [0.6-54.1], 69.2% [27.7-88.4], 54.8% [4.0-80.1] and 40.4% [2.0-66.8] of patients, respectively.

CONCLUSION

Dietary advice is not systematically provided to patients with CHD, and considerable differences exist between European countries.

Necessary Knowledge and Skills for Dietitians in Saudi Arabia: A Qualitative Study

BACKGROUND

Dietitians play a major role in health promotion and chronic diseases prevention. Graduates from clinical nutrition and dietetics major should be equipped with the necessary knowledge and skills for their role to be more effective. The purpose of this study is to investigate the knowledge and skills needed by current and future graduates in clinical nutrition and dietetics.

METHODS

In this qualitative study, structured interviews by focus groups were conducted. Dietitians from different governmental and private sectors were invited to participate in the study. Focus groups were stratified based on the participants' gender and years of experience to promote self-disclosure. Abridged transcript of relevant and useful points was performed. The transcripts were coded and cross-validated by two researchers.

RESULTS

A total of four focus groups were conducted. Two focus groups comprise 9 male participants and the other two comprise 10 females. The age of participants ranged 25-40 years old. Participants were employees in Riyadh city with experience that ranged 3-10 years old. Nine themes of the necessary knowledge and skills were identified.

CONCLUSION

It is recommended for the Saudi government to create standards specialised for clinical nutrition and dietetics undergraduate and graduate programmes.

Is continuing medical education sufficient? Assessing the clinical nutrition knowledge of medical doctors

OBJECTIVES

Provision of nutritional support (NS) can improve disease outcome and shorten hospital length of stay. NS, often prescribed by medical doctors, requires adequate clinical nutrition (CN) expertise. The aim of this study was to investigate self-perceived and actual CN knowledge among medical doctors in Greece.

METHODS

Internal medicine physicians and surgical specialties (residents and specialized) were asked to self-evaluate their CN expertise, via a seven-item questionnaire and to complete a 20-question multiple-choice test on CN topics, with the aim of evaluating their actual CN knowledge. Participants were discouraged from accessing literature/information during the completion of either questionnaire.

RESULTS

Of 182 invited medical doctors, 115 (50.4% surgical specialties) participated in the study (63.2% response rate). The majority of participants (65.2%) demonstrated inadequate CN knowledge, with 30.4% of those scoring low having a high self-perception of their CN expertise. Comparison of perceived and actual CN knowledge revealed that only 56.5% of the participants estimated their knowledge correctly. Those who had participated in CN continuous medical education courses demonstrated increased related expertise (P = 0.002).

CONCLUSIONS

Medical doctors in Greece demonstrate low knowledge of fundamental CN principles, jeopardizing the provision of high-quality and efficient NS. Most importantly, the majority of participants overestimated their CN knowledge and prescribe artificial nutrition or participate in related decision making. Physicians' CN knowledge should be enhanced accordingly, either by attending CN modules during their studies, by participating in basic and advanced courses or CN-specific continuous medical education, or both.

Nationwide survey of nutritional management in an Asian upper-middle income developing country government hospitals: Combination of quantitative survey and focus group discussion

BACKGROUND & AIMS

The objective of this study was to identify the differences in pattern, process, and management of nutrition care in government hospitals in Thailand (an Asian upper-middle income developing country).

METHODS

This is a combination of a quantitative nationwide questionnaire survey and focus group discussions. A total of 2300 questionnaires were sent to government hospitals across Thailand. The responders were divided by routine-nutrition screening/assessment unit vs. non-routine-nutrition screening/assessment unit (RSA vs. NRSA). The comparison between the groups was reported as percentage and cross-sectional odds ratio (CS-OR) with 95% confidence interval (CI). The significant difference was defined as p < 0.05.

RESULTS

A total of 814 questionnaires (35.4%) were returned. The three most common tools of RSA were 42% Bhumibol Nutrition Triage (BNT), 21.2% Subjective Global Assessment (SGA) and 20.2% Nutrition Alert Form (NAF). The RSA was significantly higher in proportion for the role of the nurses (RSA vs. NRSA; CS-OR [95% CI]: 68.3% vs. 11.9%; 15.8 [11.1 to 22.7]; p < 0.01), the multidisciplinary team (90.1% vs. 0.4%; 2266 [558 to 1909]; p < 0.01), the nutrition management guidelines (60.6% vs. 2.8%; 53.6 [29.6 to 102.8]; p < 0.01), the nurse-driven enteral feeding protocols (31.7% vs. 17.5%; 2.2 [1.5 to 3.1]; p < 0.01) and preference for hospital formula enteral nutrition (91.4% vs.69.7%; 4.6 [2.9 to 7.4]; p < 0.01). For focus group discussions, the main barrier of RSA implementation was that there was no national recommendation of a screening/assessment tool, inconsistency of policy and reimbursement, and professional and acceptable workload.

CONCLUSION

Nutrition screening/assessment tools were found to be varied in Thailand. RSA affected the nutrition management working process and the types of nutrition support. The main barriers of RSA implementation were inconsistency of policy and reimbursement, acceptable workload, and national guidance as regards - screening/assessment tools.

The impact of whole-of-diet interventions on depression and anxiety: a systematic review of randomised controlled trials

Objective

Non-pharmacological approaches to the treatment of depression and anxiety are of increasing importance, with emerging evidence supporting a role for lifestyle factors in the development of these disorders. Observational evidence supports a relationship between habitual diet quality and depression. Less is known about the causative effects of diet on mental health outcomes. Therefore a systematic review was undertaken of randomised controlled trials of dietary interventions that used depression and/or anxiety outcomes and sought to identify characteristics of programme success.

Design

A systematic search of the Cochrane, MEDLINE, EMBASE, CINAHL, PubMed and PyscInfo databases was conducted for articles published between April 1971 and May 2014.

Results

Of the 1274 articles identified, seventeen met eligibility criteria and were included. All reported depression outcomes and ten reported anxiety or total mood disturbance. Compared with a control condition, almost half (47 %) of the studies observed significant effects on depression scores in favour of the treatment group. The remaining studies reported a null effect. Effective dietary interventions were based on a single delivery mode, employed a dietitian and were less likely to recommend reducing red meat intake, select leaner meat products or follow a low-cholesterol diet.

Conclusions

Although there was a high level of heterogeneity, we found some evidence for dietary interventions improving depression outcomes. However, as only one trial specifically investigated the impact of a dietary intervention in individuals with clinical depression, appropriately powered trials that examine the effects of dietary improvement on mental health outcomes in those with clinical disorders are required.

Screening for dietary fat intake of grade six children: self-assessment vs. maternal assessment

As part of justifiable nutrition promotion, this study aimed to determine internal consistency of a dietary fat screener and to compare self-assessment to maternal assessment of fat intake of grade six (about 12 years old) learners in a South African public primary school. The children completed in school a pictorial, quantitative food frequency-type screener consisting of 10 high-fat food categories; mothers individually completed a text version. Internal consistency was measured with item-total correlations, Cronbach's alpha and the split-half method. Child-mother comparison was based on kappa (κ) statistics, McNemar's tests, Wilcoxon signed-rank test and the Bland-Altman method. In total, 101 (93.5%) children and 78 (72.2%) mothers responded. The screener was internally consistent, regardless of data source and statistical technique. For portion sizes and frequency of intake, children consistently reported higher intake than mothers. This resulted in systematic error, also evidenced by a significant difference from zero for the difference between child's and mother's final test scores for the whole group, and for boys and girls separately (always P < 0.001). In 76% of the pairs, classification into high fat or prudent intake was identical, yet the chance-corrected agreement was poor (κ = 0.16) and non-agreement was non-symmetrical (P = 0.001). Children and mothers reported high fat intakes (93% and 75%, respectively). It was concluded that the dietary fat screener was internally consistent, yet children and mothers did not agree in their assessment. The high fat intakes reported by children and mothers warrant measurement refinement and implementation of primary prevention programmes.

Position of the Academy of Nutrition and Dietetics: the role of nutrition in health promotion and chronic disease prevention

It is the position of the Academy of Nutrition and Dietetics that primary prevention is the most effective and affordable method to prevent chronic disease, and that dietary intervention positively impacts health outcomes across the life span. Registered dietitians and dietetic technicians, registered are critical members of health care teams and are essential to delivering nutrition-focused preventive services in clinical and community settings, advocating for policy and programmatic initiatives, and leading research in disease prevention and health promotion. Health-promotion and disease-prevention strategies are effective at reducing morbidity and mortality and improving quality of life, and have a significant impact on the leading causes of disease. By applying these principles within a social ecological theoretical framework, positive influence can be applied across the spectrum of engagement: at intrapersonal, interpersonal, institutional, community, and public policy levels. Through the application of efficacious and cost-effective interventions, registered dietitians and dietetic technicians, registered, can positively impact public health as well as health outcomes for the individuals that they counsel. This position paper supports the "Practice Paper of the Academy of Nutrition and Dietetics: The Role of Nutrition in Health Promotion and Chronic Disease Prevention" published on the Academy's website at: www.eatright.org/positions.

Development and validation of the Diet Quality Tool for use in cardiovascular disease prevention settings

The aim of this study was to develop and evaluate a dietary screening tool for use in a secondary cardiovascular disease (CVD) prevention setting to identify an individual's overall dietary quality. The Diet Quality Tool (DQT) was validated against a 4-day food diary for 37 individuals with established CVD attending cardiac rehabilitation. Construct validity was demonstrated for % energy from saturated fat (P=0.002, r=-0.500), dietary fibre (P<0.001, r=0.559) and omega-3 fatty acids (P=0.048, r=0.327). Criterion validity was established with a significant difference found between mean (95% CI) dietary intakes of fibre (28.2g, 4.4 to 17.3) and % total energy from saturated fat (10.6%, -4.8 to -0.8) for those with better DQT scores (>60%) versus those with poorer scores (≤60%) when compared with 4-day food diary nutrient values. The usefulness of the DQT was confirmed by both patients (n=25) and cardiac rehabilitation health professionals (n=8). The DQT was found to be a valid and useful dietary assessment tool with potential for use in a secondary CVD prevention setting. The tool has the capacity to be used in a wider variety of settings and further refinement of the tool would enable a greater amount of nutrients to be reliably screened.

General practitioners' decision to refer patients to dietitians: insight into the clinical reasoning process

The aim of this project was to describe general practitioners' (GPs') decision-making process for reducing nutrition risk in cardiac patients through referring a patient to a dietitian. The setting was primary care practices in Victoria. The method we employed was mixed methods research: in Study 1, 30 GPs were interviewed. Recorded interviews were transcribed and narratives analysed thematically. Study 2 involved a survey of statewide random sample of GPs. Frequencies and analyses of variance were used to explore the impact of demographic variables on decisions to refer. We found that the referral decision involved four elements: (i) synthesising management information; (ii) forecasting outcomes; (iii) planning management; and (iv) actioning referrals. GPs applied cognitive and collaborative strategies to develop a treatment plan. In Study 2, doctors (248 GPs, 30%) concurred with identified barriers/enabling factors for patients' referral. There was no association between GPs' sex, age or hours worked per week and referral factors. We conclude that a GP's judgment to offer a dietetic referral to an adult patient is a four element reasoning process. Attention to how these elements interact may assist clinical decision making. Apart from the sole use of prescribed medications/surgical procedures for cardiac care, patients offered a dietetic referral were those who were considered able to commit to dietary change and who were willing to attend a dietetic consultation. Improvements in provision of patients' nutrition intervention information to GPs are needed. Further investigation is justified to determine how to resolve this practice gap.

Nutritional and metabolic status of HIV-positive patients with lipodystrophy during one year of follow-up

OBJECTIVES

The aim of this prospective study was to compare changes in lipid metabolism and nutritional status after either 6 and 12 months of follow-up in subjects with lipodystrophy syndrome after traditional lifestyle therapy with or without fibric acid analogue intervention (bezafibrate and clofibrate).

METHODS

Food intake, alterations in body composition and metabolic abnormalities were assessed in subjects with lipodystrophy syndrome at the beginning of the study. The nutritional status and metabolic alterations of the subjects were monitored, and the subjects received nutritional counseling each time they were seen. The subjects were monitored either two times over a period no longer than six months (Group A; n = 18) or three times over a period of at least 12 months (Group B; n = 35). All of the subjects underwent nutrition counseling that was based on behavior modification. The fibric acid analogue was only given to patients with serum triglyceride levels above 400 mg/dL.

RESULTS

After six months of follow-up, Group A showed no alterations in the experimental parameters. After twelve months, there was a decrease in serum triglyceride levels (410.4 ± 235.5 vs. 307.7 ± 150.5 mg/dL, p < 0.05) and an increase in both HDLc levels (37.9 ± 36.6 vs. 44.9 ± 27.9 mg/dL, p,0.05) and lean mass (79.9 ± 7.8 vs. 80.3 ± 9.9 %, p < 0.05) in Group B.

CONCLUSION

After one year of follow-up (three sessions of nutritional and medical counseling), the metabolic parameters of the subjects with lipodystrophy improved after traditional lifestyle therapy with or without fibric acid analogue intervention.

Long-term secondary prevention programs after cardiac rehabilitation for the reduction of future cardiovascular events: focus on regular physical activity

Cardiac rehabilitation/secondary prevention programs are recognized as integral to the comprehensive care of patients with coronary heart disease, and as such are recommended in most contemporary clinical practice guidelines. The interventions are aimed at reducing disability, optimizing cardiovascular risk reduction by drug therapy and promoting healthy behavior. Healthy lifestyle habits must be recognized as capable of substantially reducing the risk for cardiovascular events in patients with coronary heart disease. This review highlights the recommended components of cardiac rehabilitation/secondary prevention programs, with special emphasis on regular physical activity.

Drugs are not enough: the metabolic syndrome--a call for intensive therapeutic lifestyle change

Whether intensive pharmacologic cardiovascular risk factor management reduces metabolic syndrome (MetS) prevalence is unknown. The authors compared the number of secondary prevention medications and National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III)-defined MetS prevalence in coronary artery disease patients entering cardiac rehabilitation from 1996 to 2001 (period 1, n=516) with those entering from 2002 to 2006 (period 2, n=609). Age, sex, and ethnicity were similar in both periods. From period 1 to period 2, participants took more secondary prevention medications (2.8+/-1.3 vs 3.5+/-1.0, P<.001). Prevalence of low high-density lipoprotein cholesterol (66% vs 66%), diabetes (37% vs 38%), and hypertension (81% vs 81%) were unchanged. The prevalence of hypertriglyceridemia decreased (48% vs 36%, P<.001), but the proportion meeting criteria for elevated waist circumference increased (51% vs 58%, P<.05), resulting in no change in overall MetS prevalence (60% vs 59%, P=NS). More emphasis on therapeutic lifestyle change in addition to intensive pharmacologic therapy is needed to reduce MetS prevalence in patients with coronary artery disease.
