The evidence for the effectiveness of medical nutrition therapy in diabetes management

Enhancement of the Performance of Large Language Models in Diabetes Education through Retrieval-Augmented Generation: Comparative Study

BACKGROUND

Large language models (LLMs) demonstrated advanced performance in processing clinical information. However, commercially available LLMs lack specialized medical knowledge and remain susceptible to generating inaccurate information. Given the need for self-management in diabetes, patients commonly seek information online. We introduce the Retrieval-augmented Information System for Enhancement (RISE) framework and evaluate its performance in enhancing LLMs to provide accurate responses to diabetes-related inquiries.

OBJECTIVE

This study aimed to evaluate the potential of the RISE framework, an information retrieval and augmentation tool, to improve the LLM's performance to accurately and safely respond to diabetes-related inquiries.

METHODS

The RISE, an innovative retrieval augmentation framework, comprises 4 steps: rewriting query, information retrieval, summarization, and execution. Using a set of 43 common diabetes-related questions, we evaluated 3 base LLMs (GPT-4, Anthropic Claude 2, Google Bard) and their RISE-enhanced versions respectively. Assessments were conducted by clinicians for accuracy and comprehensiveness and by patients for understandability.

RESULTS

The integration of RISE significantly improved the accuracy and comprehensiveness of responses from all 3 base LLMs. On average, the percentage of accurate responses increased by 12% (15/129) with RISE. Specifically, the rates of accurate responses increased by 7% (3/43) for GPT-4, 19% (8/43) for Claude 2, and 9% (4/43) for Google Bard. The framework also enhanced response comprehensiveness, with mean scores improving by 0.44 (SD 0.10). Understandability was also enhanced by 0.19 (SD 0.13) on average. Data collection was conducted from September 30, 2023 to February 5, 2024.

CONCLUSIONS

The RISE significantly improves LLMs' performance in responding to diabetes-related inquiries, enhancing accuracy, comprehensiveness, and understandability. These improvements have crucial implications for RISE's future role in patient education and chronic illness self-management, which contributes to relieving medical resource pressures and raising public awareness of medical knowledge.

Exploring Food Preferences as a Pre-Step for Developing Diabetes-Friendly Options in Adults with Diabetes and Prediabetes

Given the low compliance with healthy eating among patients with diabetes, personalized dietary plans incorporating their food preferences are urgently needed. However, few studies have explored the food preferences of adults with diabetes or prediabetes (AdDMP). We aimed to examine taste and food preferences among AdDMP, comparing them by sex, age, and weight status. A total of 415 AdDMP completed the survey via Amazon Mechanical Turk in 2023 (53% women, 47% men; 20-70 years old). Food/taste preferences were measured using Likert-type scales for six taste-cluster food groups, as well as basic tastes/spicy flavor. Open-ended questions assessed comfort, favorite, and least favorite foods, which were then categorized into five groups. Independent t-tests, analysis of variance, and Tukey-HSD were performed to compare outcomes across the groups. Men, the 41-70-year-old group, and the obese group regarded warm food as a comfort food more than in other comparable groups, while women and the 20-30-year-old group tend to prefer fruits and vegetables. Additionally, men expressed a significantly higher preference for salty-/umami-/fat-tasting foods compared to women. These findings underscore the need to align dietary expectations with reality for AdDMP. Future research should focus on strategies to accommodate their preferences within a healthy eating framework.

Optimizing the lifestyle of patients with type 2 diabetes mellitus - Systematic review on the effects of combined diet-and-exercise interventions

AIM

To investigate the effects of combined diet-and-exercise interventions in patients with type 2 diabetes mellitus (T2DM).

DATA SYNTHESIS

A systematic literature search was conducted on PubMed, Web of Science, SPORTDiscus and BISp Surf databases (latest update in June 2024). A total of 14706 records was identified. After screening procedures, 11 randomized controlled trials (n = 24 reports) were included. The included studies compared either the effects of a) a combined intervention versus a diet-only intervention or b) different combinations of diet and exercise. The overall quality of the included study reports was moderate (evaluated with the Risk of Bias 2 (RoB2) tool). Effects of adding exercise to a (calorie-restricted) diet were primarily reflected in increased physical fitness/performance. In far fewer cases, additional beneficial effects on glycemic control, number of subjects taking medication, body weight, body composition, or lipid profile were reported. Combined with regular exercise, an energy-restricted low-carbohydrate (LC) diet with either high-fat (HF) or high-protein (HP) contents showed superior effects compared with an energy-matched conventional (CONV) diet in terms of improvements in medication use (HF-LC versus CONV diet), lipids (HF-LC or HP-LC versus CONV diet) or wellbeing (HP-LC versus CONV diet) in some studies.

CONCLUSIONS

Complementing a dietary intervention with regular exercise can have additional health benefits in T2DM, specifically improved physical fitness/performance. LC diets might be superior to other diets when combined with regular exercise. Other diet-and-exercise combinations than those analyzed in this review need to be investigated.

Modern Management of Cardiometabolic Continuum: From Overweight/Obesity to Prediabetes/Type 2 Diabetes Mellitus. Recommendations from the Eastern and Southern Europe Diabetes and Obesity Expert Group

The increasing global incidence of obesity and type 2 diabetes mellitus (T2D) underscores the urgency of addressing these interconnected health challenges. Obesity enhances genetic and environmental influences on T2D, being not only a primary risk factor but also exacerbating its severity. The complex mechanisms linking obesity and T2D involve adiposity-driven changes in β-cell function, adipose tissue functioning, and multi-organ insulin resistance (IR). Early detection and tailored treatment of T2D and obesity are crucial to mitigate future complications. Moreover, personalized and early intensified therapy considering the presence of comorbidities can delay disease progression and diminish the risk of cardiorenal complications. Employing combination therapies and embracing a disease-modifying strategy are paramount. Clinical trials provide evidence confirming the efficacy and safety of glucagon-like peptide 1 receptor agonists (GLP-1 RAs). Their use is associated with substantial and durable body weight reduction, exceeding 15%, and improved glucose control which further translate into T2D prevention, possible disease remission, and improvement of cardiometabolic risk factors and associated complications. Therefore, on the basis of clinical experience and current evidence, the Eastern and Southern Europe Diabetes and Obesity Expert Group recommends a personalized, polymodal approach (comprising GLP-1 RAs) tailored to individual patient's disease phenotype to optimize diabetes and obesity therapy. We also expect that the increasing availability of dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) agonists will significantly contribute to the modern management of the cardiometabolic continuum.

Effects of almond consumption compared with the consumption of traditional isocaloric cereal/pulse-based snacks on glycaemic control and gut health in adults with pre-diabetes in rural India: protocol for a 16-week, parallel-arm, cluster randomised controlled trial

INTRODUCTION

Almonds have prebiotic potential to maintain gut health and regulate glycaemia. Western studies have shown their positive effects on preventing non-communicable diseases like diabetes and cardiovascular diseases. However, there is a lack of research involving Asian Indians, who have a higher predisposition to diabetes due to their unique 'Asian phenotype'. Therefore, this study aims to evaluate the impact of almond supplementation on glycaemic control and gut health in adults with pre-diabetes in rural India through a randomised clinical trial.

METHODS AND ANALYSIS

A parallel cluster randomised controlled trial with 178 participants with pre-diabetes (assigned 1:1) aged 20-50 years, of both genders, with a body mass index of 18.9-25 kg/m2, will be conducted in rural areas of Chikkaballapur, Kolar and Rural Bangalore districts in India. The intervention group will receive 56 g of almonds as mid-morning snacks for 16 weeks, while the control group will receive cereal/pulse-based traditional isocaloric snacks under the closed supervision of the study investigators. The primary outcome of the study is HbA1c measured at the 16th week. The secondary outcomes-anthropometry, clinical and other biochemical parameters-will be measured at 0th, 8th and 16th weeks, and a subgroup of 120 participants will undergo gut health analysis. Glucagon-like peptide 1 analysis will be conducted on 30 participants at 0th and 16th weeks. Statistical analysis will be performed using SPSS for Windows V.27.0, and both intention-to-treat and per-protocol analyses will be conducted.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Institutional Ethics Committee at Ramaiah Medical College, Bangalore, Karnataka, India (DRPEFP7672021). We will obtain the informed written consent of the participants prior to screening and enrolling them in the study. Results from this trial will be disseminated through publication in peer-reviewed journals and scientific gatherings.

Reversal of type 2 diabetes mellitus through integrated Ayurveda dietary protocol - A case report

Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic disorder of hyperglycemia has close link with obesity and insulin resistance. Standard approaches in T2DM management are lifestyle management and Pharmacotherapy. Dietary management in T2DM was found to be safe and effective. In India, studies on reversal of T2DM through diet were less found. Presenting a case of female aged 31 years with T2DM (HbA1c-13.5) was successfully reversed diabetes with dietary principles of Indian traditional medicine (Ayurveda diet) and therapeutic yoga practices. Pre and post assessment of Glycaemic parameters (HbA1C, FBS, and PPBS), Lipid profiles, Insulin resistance parameter (HOMA IR) were done. Major outcome of this case is greater reduction of HbA1c from inadequate control to near normal. Marked changes observed in weight, BMI and Waist circumference. A change in Homa IR indicates improvement in insulin resistance. Ayurveda dietary management training include Therapeutic fasting [Two meal method], meals include nutrient dense wholesome food, Indian millet based diet, herbal recipes [therapeutic food/herbal drinks, smoothies and plant juices] and eat only when hungry method. Yoga include complete sequel of body loosening practices, surya namaskara, yogic postures and breathing and meditative techniques practiced for specified period [60 min].This case showed effectiveness of Ayurveda diet and Yoga practices in reversing the insulin resistance, help to maintain the glycemic parameters .In addition, patient was able to loose body weight, waist circumference & serum triglyceride levels. Patient can able to withstand her diabetic profile in normal without any pharmacotherapy intervention.

Patients with diabetes and obesity exhibit characteristics in eating and coping behaviors and personality traits

Aims/introduction

In patients with diabetes, obesity is an aggravating factor for glycemic control and its vascular complications. However, the psychological and behavioral characteristics of those patients with obesity have not been fully clarified. This study investigated eating and coping behavior, personality traits, quality of life (QOL), and depression status in patients with diabetes with or without obesity.

Materials and methods

Questionnaires obtained from 567 patients with diabetes at Dokkyo Medical University were analyzed. Eating behavior, coping behavior, personality traits, QOL, and depression status were evaluated by the Eating Behavior Questionnaire, Brief COPE, Japanese Ten-Item Personality Inventory, EuroQol 5 Dimensions-5 Level, and Patient Health Questionnaire-9, respectively. Participants were divided according to body mass index (BMI) into a non-obese group (BMI < 25), obese group (BMI 25-35), and high-degree obese group (BMI ≥ 35), and results were compared between groups.

Results

On all items of the Eating Behavior Questionnaire, scores were higher in the obese and high-degree obese groups than non-obese group, indicating worse eating behavior. In coping behavior, significant intergroup differences were found in self-distraction, substance use, using emotional support, using instrumental support, and venting. As for personality traits, the obese group had significantly lower conscientiousness and higher emotional instability than the non-obese group. There was no significant difference in QOL or depression status.

Conclusions

These results suggest that there are some characteristics in eating and coping behaviors and some personality traits between obese and non-obese patients with diabetes. Treatment based on such characteristics may be useful for patients with diabetes and obesity.

Knowledge, Attitude, and Practice of Orthopedic Manual Physical Therapists Toward Lifestyle Screening and Education: A Descriptive Study

INTRODUCTION

Lifestyle-focused rehabilitation plans need to become part of the standard system of care for the treatment of chronic diseases. To achieve this goal, the KAP of rehabilitation professionals toward lifestyle medicine needs to be understood. This study investigated the niche of orthopedic manual physical therapy and is purposed as a foundational model for continued research.

METHOD

A survey instrument was designed to investigate the KAP of orthopedic manual physical therapists toward lifestyle screening and education.

RESULTS

There were 155 participants of which 58.1-72.3% reported frequently talking to their patients about lifestyle topics, while 78.1-80.6% felt highly confident and competent while doing so. Additionally, 92.9-94.8% thought that lifestyle screening and education was important and that physical therapists should be doing it. Participants discussed exercise most frequently with their patients (96.1%) and alcohol the least (12.9%). Participants with advanced degrees (ie, PhD or DSc) had significantly higher Practice (MΔ= -3.755, P = .001) and Knowledge (MΔ= -4.14904, P = .020) ratings than those with entry-level physical therapy degrees.

CONCLUSION

There was strong acceptance of lifestyle screening and education in orthopedic manual physical therapy with an emphasis on exercise. This study provides a foundational basis for continued research.

Implementation rate of diabetic self-management education and support for Japanese people with diabetes using the National Database

People with diabetes are encouraged to receive diabetes self-management education and support (DSMES) appropriately. However, in Japan, the implementation rates of DSMES are not known. DSMES implementation rates were calculated using the National Database of claims data, which included nearly all insurance-covered medical procedures. The study enrolled participants who received regular antidiabetic medications between April 2017 and March 2018. The implementation rates of DSMES-related care were calculated by characteristics, visiting medical facilities and prefectures. In 4,465,513 participants receiving antidiabetic medications (men, 57.8%; insulin use, 14.1%), nutrition guidance (5.6%) was the most frequently provided care type. Insulin users and participants visiting Japan Diabetes Society-certified and large medical institutions had higher implementation rates of nutrition guidance. DSMES-related care might not be provided adequately for Japanese people with diabetes. Further studies are needed to develop an optimal diabetes care system.

Weight management using meal replacements and cardiometabolic risk reduction in individuals with pre-diabetes and features of metabolic syndrome: A systematic review and meta-analysis of randomized controlled trials

This review synthesized the evidence from randomized controlled trials comparing the effect of meal replacements (MRs) as part of a weight loss intervention with conventional food-based weight loss diets on cardiometabolic risk in individuals with pre-diabetes and features of metabolic syndrome. MEDLINE, EMBASE, and Cochrane Library were searched through January 16, 2024. Data were pooled using the generic inverse variance method and expressed as mean difference [95% confidence intervals]. The overall certainty of the evidence was assessed using GRADE. Ten trials (n = 1254) met the eligibility criteria. MRs led to greater reductions in body weight (-1.38 kg [-1.81, -0.95]), body mass index (BMI, -0.56 kg/m2 [-0.78, -0.34]), waist circumference (-1.17 cm [-1.93, -0.41]), HbA1c (-0.11% [-0.22, 0.00]), LDL-c (-0.18 mmol/L [-0.28, -0.08]), non-HDL-c (-0.17 mmol/L [-0.33, -0.01]), and systolic blood pressure (-2.22 mmHg [-4.20, -0.23]). The overall certainty of the evidence was low to moderate owing to imprecision and/or inconsistency. The available evidence suggests that incorporating MRs into a weight loss intervention leads to small important reductions in body weight, BMI, LDL-c, non-HDL-c, and systolic blood pressure, and trivial reductions in waist circumference and HbA1c, beyond that seen with conventional food-based weight loss diets.

Real-world Impact of 3 and 4.5 mg Doses of Dulaglutide on Weight and Hemoglobin A1c in Patients With Type 2 Diabetes Mellitus

BACKGROUND

Limited real-world data on the benefits and risks associated with 3 and 4.5 mg doses of dulaglutide currently exists, making it difficult to determine the impact of dose titration for patients currently managed with dulaglutide 1.5 mg weekly.

OBJECTIVE

To determine the impact of dulaglutide 3 and 4.5 mg doses on weight and hemoglobin A1c (HbA1c) in patients with type 2 diabetes mellitus (T2DM), in clinical practice.

METHODS

Retrospective, observational study of adult T2DM patients receiving dulaglutide 3 or 4.5 mg weekly within a large, university-affiliated, primary care network. The primary outcome was change in weight and HbA1c from baseline to 24 weeks. Secondary outcomes included incremental changes in weight and HbA1c, and describing trends related to dose reductions.

RESULTS

Ninety-five patients were included, 62 in the dulaglutide 3 mg group and 33 in the dulaglutide 4.5 mg group. After 24 weeks, the mean changes in weight and HbA1c from baseline were -1.8 kg (P < 0.01) and -0.4% (P < 0.01) in the 3 mg group, and -4.2 kg (P < 0.01) and -0.4% (P = 0.119) in the 4.5 mg group. Incremental change in weight and HbA1c among patients who were titrated from dulaglutide 3 to 4.5 mg weekly were -2.6 kg (P < 0.01) and -0.2% (P = 0.04), respectively.

CONCLUSION AND RELEVANCE

Titration from dulaglutide 1.5 to 3 mg resulted in significant reductions in weight and HbA1c after 24 weeks. Additional, statistically significant, reductions in weight and HbA1c were seen when patients were further titrated to dulaglutide 4.5 mg weekly.

Treat Obesity to Treat Type 2 Diabetes Mellitus

Obesity, a multifactorial, relapsing chronic disease, serves as a gateway to a spectrum of metabolic, cardiovascular, mechanical and mental health problems. Over the last few decades, the global prevalence of obesity has surged nearly threefold, mirroring the escalating rates of type 2 diabetes mellitus (T2DM). This parallel trajectory strongly suggests a cause-and-effect relationship between obesity and T2DM. Extensive research indicates that even modest weight gain elevates the risk of T2DM, favoring the notion of obesity being a root cause. This perspective finds robust support in numerous studies demonstrating the preventive effects of obesity management on the onset of T2DM. Beyond prevention, obesity management has been shown to enhance remission in individuals with T2DM and to decrease microvascular complications, cardiovascular risk factors, renal failure and heart failure. This evidence underpins the urgent need for global initiatives aimed at addressing obesity management as a key strategy in the prevention and management of T2DM and its complications.

Credibility of ChatGPT in the assessment of obesity in type 2 diabetes according to the guidelines

BACKGROUND

The Chat Generative Pre-trained Transformer (ChatGPT) allows students, researchers, and patients in the medical field to access information easily and has gained attention nowadays. We aimed to evaluate the credibility of ChatGPT according to the guidelines for the assessment of obesity in type 2 diabetes (T2D), which is one of the major concerns of this century.

MATERIALS AND METHOD

In this cross-sectional non-human subject study, experienced endocrinologists posed 20 questions to ChatGPT in subsections, which were assessments and different treatment options for obesity according to the American Diabetes Association and American Association of Clinical Endocrinology guidelines. The responses of ChatGPT were classified into four categories: compatible, compatible but insufficient, partially incompatible and incompatible with the guidelines.

RESULTS

ChatGPT demonstrated a systematic approach to answering questions and recommended consulting a healthcare provider to receive personalized advice based on the specific health needs and circumstances of patients. The compatibility of ChatGPT with the guidelines was 100% in the assessment of obesity in type 2 diabetes; however, it was lower in the therapy sections, which included nutritional, medical, and surgical approaches to weight loss. Furthermore, ChatGPT required additional prompts for responses that were evaluated as "compatible but insufficient" to provide all the information in the guidelines.

CONCLUSION

The assessment and management of obesity in T2D are highly individualized. Despite ChatGPT's comprehensive and understandable responses, it should not be used as a substitute for healthcare professionals' patient-centered approach.

How quality of life is measured in studies of nutritional intervention: a systematic review

BACKGROUND

Nutrition care can positively affect multiple aspects of patient's health; outcomes are commonly evaluated on the basis of their impact on a patient's (i) illness-specific conditions and (ii) health-related quality of life (HRQoL). Our systematic review examined how HRQoL was measured in studies of nutritional interventions. To help future researchers select appropriate Quality of Life Questionnaires (QoLQ), we identified commonly-used instruments and their uses across populations in different regions, of different ages, and with different diseases.

METHODS

We searched EMCare, EMBASE, and Medline databases for studies that had HRQoL and nutrition intervention terms in the title, the abstract, or the MeSH term classifications "quality of life" and any of "nutrition therapy", "diet therapy", or "dietary supplements" and identified 1,113 studies for possible inclusion.We then reviewed titles, abstracts, and full texts to identify studies for final inclusion.

RESULTS

Our review of titles, abstracts, and full texts resulted in the inclusion of 116 relevant studies in our final analysis. Our review identified 14 general and 25 disease-specific QoLQ. The most-used general QoLQ were the Short-Form 36-Item Health Survey (SF-36) in 27 studies and EuroQol 5-Dimension, (EQ-5D) in 26 studies. The European Organization for Research and Treatment of Cancer Quality of life Questionnaire (EORTC-QLQ), a cancer-specific QoLQ, was the most frequently used disease-specific QoLQ (28 studies). Disease-specific QoLQ were also identified for nutrition-related diseases such as diabetes, obesity, and dysphagia. Sixteen studies used multiple QoLQ, of which eight studies included both general and disease-specific measures of HRQoL. The most studied diseases were cancer (36 studies) and malnutrition (24 studies). There were few studies focused on specific age-group populations, with only 38 studies (33%) focused on adults 65 years and older and only 4 studies focused on pediatric patients. Regional variation in QoLQ use was observed, with EQ-5D used more frequently in Europe and SF-36 more commonly used in North America.

CONCLUSIONS

Use of QoLQ to measure HRQoL is well established in the literature; both general and disease-specific instruments are now available for use. We advise further studies to examine potential benefits of using both general and disease-specific QoLQ to better understand the impact of nutritional interventions on HRQoL.

Novel Therapeutic Agents for Management of Diabetes Mellitus: A Hope for Drug Designing against Diabetes Mellitus

Diabetes mellitus (DM) is characterized by an absolute decline in insulin secretion and peripheral resistance and is the most prevalent metabolic and endocrine disorder. However, the pathogenesis of DM also includes adipocyte insulin resistance, increased glucagon secretion, increased renal glomerular glucose absorption, and neurotransmitter dysfunction. Although there is a wide spectrum of therapeutics available for glycemic control, owing to the identification of various pathogenic determinants of DM, management of DM remains challenging and complex. Current therapeutic interventions against DM focus mostly on glycemic control without considering the other pathological determinants that eventually lead to treatment failure and the progression of DM. Furthermore, long-term use of these conventionally available anti-diabetic drugs leads to various side effects, henceforth development of novel drugs against DM remains an unending search strategy for researchers. Various studies conducted in various parts of the world have proposed that these novel therapeutic interventions target multiple and alternate pathogenic hotspots involved in DM. The current review article discusses novel therapeutic options that hold particular promise to support their safety and discuss the side effects resulting from their use so that these novel candidate drugs can be effectively fabricated into potential drugs for the treatment of DM.

Emerging therapeutic options in the management of diabetes: recent trends, challenges and future directions

Diabetes is a serious health issue that causes a progressive dysregulation of carbohydrate metabolism due to insufficient insulin hormone, leading to consistently high blood glucose levels. According to the epidemiological data, the prevalence of diabetes has been increasing globally, affecting millions of individuals. It is a long-term condition that increases the risk of various diseases caused by damage to small and large blood vessels. There are two main subtypes of diabetes: type 1 and type 2, with type 2 being the most prevalent. Genetic and molecular studies have identified several genetic variants and metabolic pathways that contribute to the development and progression of diabetes. Current treatments include gene therapy, stem cell therapy, statin therapy, and other drugs. Moreover, recent advancements in therapeutics have also focused on developing novel drugs targeting these pathways, including incretin mimetics, SGLT2 inhibitors, and GLP-1 receptor agonists, which have shown promising results in improving glycemic control and reducing the risk of complications. However, these treatments are often expensive, inaccessible to patients in underdeveloped countries, and can have severe side effects. Peptides, such as glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), are being explored as a potential therapy for diabetes. These peptides are postprandial glucose-dependent pancreatic beta-cell insulin secretagogues and have received much attention as a possible treatment option. Despite these advances, diabetes remains a major health challenge, and further research is needed to develop effective treatments and prevent its complications. This review covers various aspects of diabetes, including epidemiology, genetic and molecular basis, and recent advancements in therapeutics including herbal and synthetic peptides.

Trends in health behaviors of US adults with and without Diabetes: 2007-2018

AIMS

Understanding health behaviors of people with diabetes can inform strategies to reduce diabetes-related burdens.

METHODS

We used serial cross-sectional National Health and Nutrition Examination Surveys over 2007-2018 to characterize self-reported health behaviors among non-pregnant adults, with and without self-reported diabetes. We estimated weighted proportions meeting recommended health behaviors overall and by sociodemographic and glycemic levels.

RESULTS

During 2007-2010, proportions of adults with diabetes meeting recommendations were: 61.9 % for added sugar consumption (<10 % of total calories), 17.2 % for physical activity, 68.2 % for weight management, 14.4 % avoided alcohol, 57.5 % avoided tobacco, 34.1 % got adequate sleep, and 97.5 % saw a healthcare provider (compared with 19.2 %, 33.6 %, 68.8 %, 8.5 %, 44.2 %, 33.0 %, and 82.6 % respectively, among those without diabetes). During 2015-2018, adjusted analyses showed more adults with diabetes met sleep (+16.7 percentage-points[pp]; 95 % CI: 10.6,22.8) and physical activity goals (+8.3 pp; 95 % CI: 3.8,12.8), and fewer met added sugar recommendations (-8.8 pp; 95 % CI -14.7, -2.9). Meeting added sugar, physical activity, and weight management varied by age, education, and glycemic level, but not race and ethnicity.

CONCLUSIONS

During 2007-2018, there was some improvement in health behaviors. Improving self-management may require targeted interventions for different segments, like age groups or glycemic levels, among those with diabetes.

An AI Dietitian for Type 2 Diabetes Mellitus Management Based on Large Language and Image Recognition Models: Preclinical Concept Validation Study

BACKGROUND

Nutritional management for patients with diabetes in China is a significant challenge due to the low supply of registered clinical dietitians. To address this, an artificial intelligence (AI)-based nutritionist program that uses advanced language and image recognition models was created. This program can identify ingredients from images of a patient's meal and offer nutritional guidance and dietary recommendations.

OBJECTIVE

The primary objective of this study is to evaluate the competence of the models that support this program.

METHODS

The potential of an AI nutritionist program for patients with type 2 diabetes mellitus (T2DM) was evaluated through a multistep process. First, a survey was conducted among patients with T2DM and endocrinologists to identify knowledge gaps in dietary practices. ChatGPT and GPT 4.0 were then tested through the Chinese Registered Dietitian Examination to assess their proficiency in providing evidence-based dietary advice. ChatGPT's responses to common questions about medical nutrition therapy were compared with expert responses by professional dietitians to evaluate its proficiency. The model's food recommendations were scrutinized for consistency with expert advice. A deep learning-based image recognition model was developed for food identification at the ingredient level, and its performance was compared with existing models. Finally, a user-friendly app was developed, integrating the capabilities of language and image recognition models to potentially improve care for patients with T2DM.

RESULTS

Most patients (182/206, 88.4%) demanded more immediate and comprehensive nutritional management and education. Both ChatGPT and GPT 4.0 passed the Chinese Registered Dietitian examination. ChatGPT's food recommendations were mainly in line with best practices, except for certain foods like root vegetables and dry beans. Professional dietitians' reviews of ChatGPT's responses to common questions were largely positive, with 162 out of 168 providing favorable reviews. The multilabel image recognition model evaluation showed that the Dino V2 model achieved an average F1 score of 0.825, indicating high accuracy in recognizing ingredients.

CONCLUSIONS

The model evaluations were promising. The AI-based nutritionist program is now ready for a supervised pilot study.

Diagnosis and Non-Invasive Treatment of Obesity in Adults with Type 2 Diabetes Mellitus: A Review of Guidelines

Obesity, a chronic disease with multifactorial etiopathogenesis, is characterized by excessive accumulation of adipose tissue. Obesity prevalence is growing globally at an alarming rate. The overwhelming majority of obesity cases are caused by inappropriate lifestyles, such as overconsumption of food and inadequate physical activity. Metabolic and biochemical changes due to increased adiposity resulted in numerous comorbidities, increased all-cause mortality, and reduced quality of life. T2DM (type 2 diabetes mellitus) and obesity have many common pathogenetic points and drive each other in a vicious cycle. The aim of this article is to review obesity management guidelines and highlight the most important points. Management of both obesity-related and T2DM complications incur enormous expenses on healthcare systems. It is, therefore, paramount to provide streamlined yet custom-tailored weight management in order to avoid the negative ramifications of both diseases. Efficient obesity treatment leads to better diabetes control since some antidiabetic medications support weight reduction. Obesity treatment should be overseen by a multi-disciplinary team providing indispensable information and individually tailored regimens to patients. Weight management should be multimodal and consist chiefly of MNT (medical nutrition therapy), physical activity, and lifestyle changes. A comprehensive approach to obesity treatment may give tangible results to quality of life and comorbidities.

Study protocol for a cluster randomized controlled trial for 16 weeks to assess the effect of almond consumption on glycemic control and gut health in prediabetes adults in rural settings of India.. [DOI: 10.1101/2023.06.21.23291579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Introduction

Almonds have prebiotic potential to maintain gut health and regulate glycemia. Western studies have shown their positive effects in preventing non-communicable diseases like diabetes and CVDs. However, there is a lack of well-designed studies involving Asian Indians, who have a higher predisposition to diabetes due to their unique ‘Asian phenotype’. Therefore, this study aims to evaluate the impact of almond supplementation on glycemic control and gut health in prediabetic adults in rural India through a randomized clinical trial.

Methods and Analysis

A parallel cluster randomized controlled trial with 178 prediabetic participants aged 20-50, both genders, with a BMI of 18.9-25 kg/m2, will be conducted in rural areas of Chikkaballapur, Kolar, and rural Bangalore districts in India. The intervention group will receive 56g of almonds as mid-morning snacks for 16 weeks, while the control group will receive cereal pulse based traditional isocaloric snacks under the closed supervision of the study investigators. Anthropometry, clinical, and biochemical parameters will be measured at 0, 8th, and 16th weeks, and a subgroup of 120 participants will undergo gut health analysis. GLP 1 analysis will be conducted on 30 participants at 0 and 16th week.

ARTICLE SUMMARY

Strengths and Limitations:

-

The study is the first field-based trial in rural settings to assess the effect of almond consumption versus traditional cereal pulse-based snacks on prediabetes adults’ glycemic control and gut health.

-

The compliance management is crucially designed by performing an intervention on one-to-one closed supervision, assessment of serum tocopherol levels, and regular follow up of any adverse events.

-

The upcoming metagenomic analysis and the gut metabolites like short chain fatty acids (SCFA) and GLP 1 will significantly advance our understanding of the impact of almonds on the gut health of prediabetes adults.

-

A potential limitation of the study is that it will not be feasible to follow the participants after the post intervention period.

Metabolic control of diabetic patients assisted by private and public health care systems during the COVID-19 pandemic: A retrospective cohort study

AIMS

We sought to analyze the impacts of social restriction measures imposed by the pandemic COVID-19 on the control of metabolic parameters in diabetic patients.

METHODS

We accessed the medical records of patients who underwent clinical follow-up in the public and private health systems between July 2019 and June 2021. The sample consisted of 288 patients (111 adults and 177 older individuals). A two-way ANOVA mixed model was used to test the effects of intra- (time: baseline and after 24 months) and inter-subject factors. Linear regression analysis was used to predict the difference in body weight considering age, sex, HbA1c, health care system and insulin use.

RESULTS

Among adults, we observed an increase in body weight and LDL-c levels, especially for insulin users (p ≤ 0.05). Adults assisted by the public health care system showed higher HbA1c levels (p = 0.001). Among older individuals using insulin, blood glucose levels decreased (p = 0.019). Body weight decreased in those assisted by the private system (p = 0.005), while glycemia decreased for patients assisted by both health care systems (p = 0.043). The linear regression model confirmed that the increase in body weight was more pronounced in adults than in older individuals.

CONCLUSION

The social restriction measures imposed by the pandemic affected the metabolic control of diabetic patients, especially adults assisted by the public health care system.

Understanding Food Security as a Social Determinant of Diabetes-Related Health during Pregnancy

Gestational and pregestational diabetes during pregnancy are substantial and growing public health issues. Low-income individuals and individuals who identify as racial and ethnic minorities are disproportionately affected. Food security, which is defined as the degree to which individuals have capacity to access and obtain food, is at the center of nutritional resources and decisions for individuals with diabetes. While increasingly recognized as an important mediator of health disparities in the United States, food insecurity is understudied during pregnancy and specifically among pregnant individuals with diabetes, for whom the impact of food-related resources may be even greater. Previous research has suggested that food insecurity is associated with type 2 diabetes mellitus diagnoses and disease exacerbation in the general adult population. An emerging body of research has suggested that food insecurity during pregnancy is associated with gestational diabetes mellitus diagnoses and adverse diabetes-related outcomes. Additionally, food insecurity during pregnancy may be associated with adverse maternal and neonatal outcomes. Future research and clinical work should aim to further examine these relationships and subsequently develop evidence-based interventions to improve diabetes-related outcomes among pregnant individuals with food insecurity. The purpose of this article is to offer a working definition of food security, briefly review issues of food insecurity and diabetes, summarize research on food insecurity and diabetes-related pregnancy health, and discuss clinical recommendations and areas for future investigation. KEY POINTS: · Research on food insecurity and diabetes-related health is limited.. · The impact of food security on diabetes management and obstetric outcomes is likely significant.. · Future work to evaluate perinatal food security screening is warranted..

Trends in baseline HbA1c and body-mass index in randomised placebo-controlled trials of type 2 diabetes from 1987 to 2022: a systematic review and meta-analysis

BACKGROUND

Curbing or reversing high glycated hemoglobin (HbA1c) and body mass index (BMI) are two essential parts in the clinical management of type 2 diabetes (T2D). We delineated the changing patterns of the baseline HbA1c and BMI in patients with T2D from placebo-controlled randomised trials to reflect the unmet clinical needs.

METHODS

PubMed, Medline, Embase and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched from inception to December 19, 2022. Placebo-controlled trials of T2D with reports of baseline HbA1c and BMI were included, of which summary data from published reports were extracted. Pooled effect sizes of baseline HbA1c and BMI of from studies published in the same year were computed in Random-effects model due to the high level of heterogeneity among studies. The main outcome was correlations between the pooled baseline HbA1c, the pooled baseline BMI, and study years. This study was registered in PROSPERO as CRD42022350482.

FINDINGS

We identified 6102 studies, of which 427 placebo-controlled trials with 261, 462 participants were finally included in the study. Baseline HbA1c level declined with time (Rs = -0.665, P ＜ 0.0001, I² = 99.4%). Baseline BMI increased over the past 35 years (R = 0.464, P = 0.0074, I² = 99.4%), rising by around 0.70 kg/m² per decade. Patients with BMI ≤25.0 kg/m² dropped substantially from the half in 1996 to none in 2022. Patients with BMI ranging from 25 kg/m² to 30 kg/m² stabilized at 30-40% since 2000.

INTERPRETATION

A substantial decline in baseline HbA1c levels and a constant increase in baseline BMI levels was found in placebo-controlled trials through the past 35 years, which indicated the improvement in glycemic control and the urgency for the management of obesity in T2D.

SISTER (Sisters Inspiring Sisters to Engage in Relevant Diabetes Self-Care) Diabetes Study: Protocol for diabetes medical nutrition therapy randomized clinical trial among African American women

BACKGROUND

African American (AA) women with type 2 diabetes (T2D) carry disproportionate diabetes-related morbidity and mortality burdens. Diabetes medical nutrition therapy (MNT) improves glycemic, blood pressure, and cholesterol control, all critical in preventing and reducing diabetes complications. Yet, MNT does not address low motivation for dietary intake management, which is frequently reported among AA women with T2D living in the Southeastern US.

METHODS

A randomized controlled trial will be used to test the central hypothesis that diabetes MNT plus culturally-tailored motivational interviewing (MI) (diabetes MNT plus MI) is more effective than diabetes MNT alone (diabetes MNT). Two hundred ninety-one Southeastern AA women who are at risk for development and/or progression of T2D complications will be randomized to diabetes MNT plus MI or diabetes MNT. Both groups will include: 1) a 3-month active intervention period, consisting of group-based, nutritionist-facilitated MNT sessions; 2) a 3-month maintenance intervention period, including one group-based, nutritionist-facilitated maintenance support session; and 3) a 6-month inactive period. Culturally-adapted MI exercises will be integrated into the diabetes MNT plus MI group only. Primary (HbA1c) and secondary (systolic blood pressure, LDL cholesterol) outcomes will be assessed at baseline and 3, 6, and 12 months following the active intervention period.

DISCUSSION

The results from this study, called the SISTER (Sisters Inspiring Sisters to Engage in Relevant Diabetes Self-Care) Diabetes Study, are vital to the adoption and uptake of rigorously-tested MNT interventions that address motivation among AA women with T2D as a way to reduce their risk and/or progression of diabetes-related complications.

The METRO study: a retrospective analysis of the efficacy of metformin for type 2 diabetes in Japan

Metformin monotherapy as first-line treatment for patients with type 2 diabetes (T2D) has been shown to effectively improve blood glucose levels and motivation to undergo treatment and prevent complications. However, no studies have reported its effect when combined with other drugs or compared the effect based on administration time. This study aimed to investigate the effect of metformin administration in Japanese patients with T2D, examine how the introduction line impacts the effect of metformin, and examine the characteristics of patients demonstrating improved blood glucose levels. Data on characteristics of patients who were newly prescribed metformin with no shifting of hypoglycemic agents in the subsequent 24-week observation period, and their age [mean, 56.8 years], body mass index [mean, 27.5 kg/m²], glycated hemoglobin [HbA1c] [mean, 8.1%], and duration of diabetes [mean, 3.0 years] were obtained from the medical records of 201 patients. The changes in HbA1c by introduction line after 24 weeks were -1.59%, -0.91%, -0.89%, and -0.65% in the first, second, third, and fourth induction lines, respectively; earlier introduction more significantly improved blood glucose. The factors significantly associated with HbA1c changes were early introduction, high baseline HbA1c, high estimated glomerular filtration rate, decreased insulin secretion, short estimated duration of diabetes, and increased metformin dose. Furthermore, factors contributing to the largest HbA1c improvement by metformin were high baseline HbA1c and early administration. Metformin is expected to lower blood glucose levels in Japanese patients with T2D, even in those with decreased insulin secretion, due to its early introduction as a first-line drug.

Fragility of cardiovascular outcome trials (CVOTs) examining nutrition interventions among patients with diabetes mellitus: a systematic review of randomized controlled trials

PURPOSE

There is controversy regarding the optimal statistical method to interpret how robust is a statistically significant result. The fragility index (FI) and the reverse fragility index (RFI) are quantitative measures that can facilitate the appraisal of a clinical trial's robustness. This study was performed to evaluate the FI and RFI of randomized controlled trials (RCTs) examining nutritional interventions in patients with diabetes mellitus, focusing on cardiovascular outcomes.

METHODS

A systematic search was conducted and relevant RCTs were identified in three databases. RCTs examining nutritional interventions (supplements or dietary patterns) in patients with DM with dichotomous primary endpoints involving cardiovascular outcomes were eligible. Data were extracted to compose 2 × 2 event tables and the FI and RFI were calculated for each comparison, using Fisher's exact test. Risk of bias (RoB) of the included RCTs was assessed with the Cochrane RoB 2.0 tool.

RESULTS

A total of 14,315 records were screened and 10 RCTs were included in the analyses. The median FI of the paired comparisons was 3 (IQR: 2-4) and the median RFI was 8 (IQR: 4.5-17). RoB and heterogeneity were low.

CONCLUSIONS

RCTs examining nutritional interventions and cardiovascular outcomes among patients with diabetes mellitus appear to be statistically fragile. Τhe FI and the RFI can be reported and interpreted as an additional perspective of a trial's robustness.

HIGHLIGHTS

• In the evidence-healthcare era, assessing how robust statistically significant results are remains a matter of controversy. • Recently, the fragility index (FI) and reverse fragility index (RFI) were proposed to assess the robustness of randomized controlled trials (RCTs) with 2 × 2 comparisons. • When applying the FI and RFI, RCTs examining nutritional interventions and cardiovascular outcomes among patients with diabetes mellitus (DM) appear to be statistically fragile. • Τhe FI and the RFI can be reported and interpreted as an additional perspective of a trial's robustness. • RCTs implementing nutrition interventions among patients with DM can improve their methodology.

Defining the Practice of Dietitians in Malaysia Using the Nutrition Care Process in Patients with Type 2 Diabetes Mellitus

(1) Background: The quality of dietetic care is crucial to improve patient outcomes. The aim of this study was to measure the current practices regarding the provision of nutrition care in type 2 diabetes mellitus (T2DM) among dietitians in Malaysia. (2) Methods: A 49-item online survey was distributed via Malaysian Dietitians’ Association and Ministry of Health Malaysia social media platforms. Self-reported dietetic practices in the management of T2DM were evaluated against practice guidelines. (3) Results: A total of 173 dietitians completed the survey, with a response rate of 62%. Three-quarters of dietitians in the public sector consulted patients within two to three weeks or more than four weeks versus less than two weeks (86.3%) among private dietitians (p-value < 0.001). More than 95% of private dietitians spent 31–60 min or more than 60 min on new cases versus 71% among public dietitians (p-value < 0.001). Group counseling was only practiced among public dietitians (36.0%). Different practice settings led to the current findings. A limited use of behavioral counseling theories and strategies was observed among dietitians from both sectors. Limited adherence to nutrition-related recommendations (62.8%) and lack of readiness for diet/lifestyle changes (45.5%) were the key challenges faced by dietitians when managing T2DM. (4) Conclusions: The survey indicates that there is a need for the development of comprehensive training to increase the utilization of behavioral counselling. Practice setting is an element to consider when designing training.

Dietitian-supported dietary intervention leads to favorable dietary changes in patients with type 2 diabetes: A randomized controlled trial

AIMS/INTRODUCTION

It remains to be fully elucidated whether nutrition education by dietitians can lead to specific positive changes in the food choices of patients with diabetes.

MATERIALS AND METHODS

A total of 96 patients with type 2 diabetes and diabetic kidney disease were randomly assigned to the intensive intervention group that received nutritional education at every outpatient visit and the control group that received nutritional education once a year. The total energy intake, energy-providing nutrients and 18 food groups were analyzed at baseline, and 1 and 2 years after the intervention in 87 patients. Furthermore, the relationship between the changes in hemoglobin A1c, body composition and changes in the total energy or energy-producing nutrient intake was analyzed in 48 patients who did not use or change hypoglycemic agents during the study period.

RESULTS

The total energy intake, carbohydrates, cereals, confections, nuts and seeds, and seasonings significantly decreased, and fish and shellfish intake significantly increased during the study period in the intensive intervention group, whereas these changes were not observed in the control group. The decrease in the total energy intake and carbohydrates after 2 years was significantly greater in the intensive intervention group than in the control group. The change in the total energy and carbohydrate intake showed a significant positive correlation with that in muscle mass. The multivariate analysis showed that the decrease in total energy intake was independently associated with that in muscle mass.

CONCLUSION

Dietitian-supported intensive dietary intervention helps improve the diet of patients with type 2 diabetes.

Impact of Dietitian-Led Nutrition Therapy of Food Order on 5-Year Glycemic Control in Outpatients with Type 2 Diabetes at Primary Care Clinic: Retrospective Cohort Study

The aim of this retrospective cohort study was to evaluate the effect of 5-year follow-up of dietitian-led medical nutrition therapy (eating vegetables before carbohydrates) on glycemic control in outpatients with type 2 diabetes (T2DM) at a primary care clinic. A total of 138 patients with dietitian-led medical nutrition therapy (intervention group) and 104 patients without dietitian-led nutrition therapy (control group) were compared for glycemic control, serum lipid, blood pressure, and diabetic complications for 5 years. Each patient in the intervention group received dietary education focused on food order (eating vegetables before carbohydrates) by dietitians. A significant improvement in HbA1c after 5 years in the intervention group [8.5 ± 1.7% (69 mmol/mol) to 7.6 ± 1.1% (59 mmol/mol), p < 0.001] was observed, whereas no change was observed in the control group [7.9 ± 1.2% (62 mmol/mol) to 8.0 ± 1.2% (63 mmol/mol)]. Dietary intake of protein, fat, carbohydrates, cholesterol, and salt in the intervention group demonstrated significant reduction, while the intake of dietary fiber significantly increased after the dietary education. Simple dietary education of ‘eating vegetables before carbohydrates’ presented by dietitians achieved good glycemic control after a 5-year period in outpatients with T2DM at primary care clinic.

U-Shaped Associations Between Body Weight Changes and Major Cardiovascular Events in Type 2 Diabetes Mellitus: A Longitudinal Follow-up Study of a Nationwide Cohort of Over 1.5 Million

OBJECTIVE

Despite the benefits of weight loss on metabolic profiles in patients with type 2 diabetes mellitus (T2DM), its association with myocardial infarction (MI), ischemic stroke (IS), atrial fibrillation (AF), heart failure (HF), and all-cause death remains elusive.

RESEARCH DESIGN AND METHODS

Using the National Health Insurance Service Database, we screened subjects who underwent general health checkups twice in a 2-year interval between 2009 and 2012. After identifying 1,522,241 patients with T2DM without a previous history of MI, IS, AF, and HF, we followed them until December 2018. Patients were stratified according to the magnitude of weight changes between two general health checkups: ≤ -10%, -10 to ≤ -5%, -5 to ≤5%, 5 to ≤10%, and >10%.

RESULTS

During the follow-up (median 7.0 years), 32,106 cases of MI, 44,406 cases of IS, 34,953 cases of AF, 68,745 cases of HF, and 84,635 all-cause deaths occurred. Patients with weight changes of -5 to ≤5% showed the lowest risk of each cardiovascular event. Both directions of weight change were associated with an increased cardiovascular risk. Stepwise increases in the risks of MI, IS, AF, HF, and all-cause death were noted with progressive weight gain (all P < 0.0001). Similarly, the more weight loss occurred, the higher the cardiovascular risks observed (all P < 0.0001). The U-shaped associations were consistently observed in both univariate and multivariate analyses. Explorative subgroup analyses also consistently showed a U-shaped association.

CONCLUSIONS

Both weight loss and gain >5% within a 2-year interval were associated with an increased risk of major cardiovascular events in patients with T2DM.

Short-term effectiveness of nutrition therapy to treat type 2 diabetes in low-income and middle-income countries: systematic review and meta-analysis of randomised controlled trials

OBJECTIVES

This review examined the evidence arising from randomised controlled trials regarding the impact of nutrition therapy on glycaemic control in people living with type 2 diabetes mellitus (T2DM) in low/middle-income countries (LMICs).

DESIGN

Systematic review and meta-analysis using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Approach.

DATA SOURCES

MEDLINE, EMBASE, Web of Science, OpenGrey and the International Clinical Trials Registry were searched (up to July 3 2020).

ELIGIBILITY CRITERIA

Trials were included if they evaluated nutrition therapy in adults diagnosed with T2DM, were conducted in LMICs, measured glycaemic control and the trial included a 3-month post-intervention assessment. Nutrition therapy was defined according to American Diabetes Association recommendations.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers screened the database. Study characteristics and outcome data were extracted using a data collection form. Meta-analyses were conducted for glycated haemoglobin (HbA1c) and fasting blood glucose. Trials were assessed for risk of bias (Cochrane Risk-of-Bias, Version 2.0) and overall certainty of evidence (GRADE).

RESULTS

Four trials met inclusion criteria (total n=463), conducted in Malaysia, Iran and South Africa. All trials focused on nutrition education with no direct prescription or manipulation of diet. Mean differences between intervention and standard care were -0.63% (95% CI -1.47% to 0.21%) for HbA1c and -13.63 mg/dL (95% CI -37.61 to 10.34) for fasting blood glucose in favour of the intervention. Given the small number of eligible trials, moderate to high risk of publication bias and serious concerns regarding consistency and precision of the evidence, certainty of evidence was deemed to be very low.

CONCLUSIONS

There is a lack of well-conducted randomised controlled trials that examine the long-term impact of nutrition therapy in LMICs, preventing firm conclusions to be made on their effectiveness. Further research is essential to discover realistic, evidence-based solutions.

Comparison of the effects of frequent versus conventional nutritional interventions in patients with type 2 diabetes mellitus: A randomized, controlled trial

AIMS/INTRODUCTION

This randomized controlled trial aimed to determine whether frequent nutritional education improves the clinical parameters associated with the onset and progression of diabetic kidney disease in type 2 diabetes mellitus patients.

MATERIALS AND METHODS

A total of 96 patients with type 2 diabetes and diabetic kidney disease were randomly assigned to the intensive intervention group that received nutritional education at every outpatient visit, and the usual intervention group that received nutritional education once a year. The anthropometric parameters, blood pressure, blood chemistry, albuminuria, protein and salt intake, and prescribed medications of 87 patients who completed the 2-year follow up were analyzed.

RESULTS

In the intensive intervention group, body mass index and salt intake significantly decreased over the study period. Hemoglobin A1c levels and body fat percentage were significantly lower in the intensive intervention group than in the usual intervention group. At the end of the 2-year intervention period, the intensive intervention group had significantly lower salt intake (8.1 vs 9.4 g/day) than the usual intervention group. A significant positive correlation was found between salt intake and albuminuria in the overall group and intensive intervention group (r = 0.26, P = 0.02, and r = 0.36, P = 0.02, respectively). The intensive intervention group had a significantly lower insulin use rate than the usual intervention group after the 2-year intervention period (18% vs 42%). No differences were found in estimated glomerular filtration rate and albuminuria.

CONCLUSION

Intensive nutritional education is useful for alleviating the risk factors associated with the onset and progression of diabetic kidney disease.

Relations of Well-Being, Coping Styles, Perception of Self-Influence on the Diabetes Course and Sociodemographic Characteristics with HbA1c and BMI Among People with Advanced Type 2 Diabetes Mellitus

PURPOSE

Assessment of the relationship between psychological and sociodemographic factors with the levels of glycated hemoglobin (HbA1c) and Body Mass Index (BMI) among people with advanced type 2 diabetes mellitus (T2DM).

PATIENTS AND METHODS

A total of 2574 persons, among them 1381 (53.7%) women, with type 2 diabetes, during the period of switching from biphasic mixtures of human insulin to insulin analogues. The age of participants ranged from 22 to 94 years (M = 63.5; SD = 9.58), and their treatment period was in the time frame from 2 years to 43 years (M = 10.2; SD = 6.1). Participants filled out a Scale for Perception of Self-Influence on the Diabetes Course, Well-Being Index WHO-5, two questions from the Brief Method of Evaluating Coping with a Disease.

RESULTS

Statistically significant correlations were found between the HbA1c levels and (1) disease duration (r_s=0.067; p < 0.001); (2) number of complications (r_s = 0.191, p < 0.001) (3) the perception of self-influence on the diabetes course (r_s=- 0.16; p < 0.001); (4) well-being (risk of depression) (r_s=- 0.10; p < 0.001). The regression analysis showed that 7% of HbA1c variability is explained by age, a perception of self-influence on the diabetes course, the number of complications, place of residence, education, BMI. The most important findings concerning BMI were found in regression analysis, which indicated a week relationship between BMI and a number of complications, perception of self-influence on the diabetes course and coping styles (3% of the resultes' variability). The group at high risk of depression had the highest levels of HbA1c.

CONCLUSION

Sociodemographic and psychological factors show weak but statistically significant relationships with the current levels of HbA1c and BMI.

Diet and Obesity-Induced Methylglyoxal Production and Links to Metabolic Disease

The obesity rate in the United States is 42.4% and has become a national epidemic. Obesity is a complex condition that is influenced by socioeconomic status, ethnicity, genetics, age, and diet. Increased consumption of a Western diet, one that is high in processed foods, red meat, and sugar content, is associated with elevated obesity rates. Factors that increase obesity risk, such as socioeconomic status, also increase consumption of a Western diet because of a limited access to healthier options and greater affordability of processed foods. Obesity is a public health threat because it increases the risk of several pathologies, including atherosclerosis, diabetes, and cancer. The molecular mechanisms linking obesity to disease onset and progression are not well understood, but a proposed mechanism is physiological changes caused by altered lipid peroxidation, glycolysis, and protein metabolism. These metabolic pathways give rise to reactive molecules such as the abundant electrophile methylglyoxal (MG), which covalently modifies nucleic acids and proteins. MG-adducts are associated with obesity-linked pathologies and may have potential for biomonitoring to determine the risk of disease onset and progression. MG-adducts may also play a role in disease progression because they are mutagenic and directly impact protein stability and function. In this review, we discuss how obesity drives metabolic alterations, how these alterations lead to MG production, the association of MG-adducts with disease, and the potential impact of MG-adducts on cellular function.

Assessment of Insulin, GLUT2 and inflammatory cytokines genes expression in pancreatic β-Cells in zebrafish (Danio rario) with overfeeding diabetes induction w/o glucose

Abstract

In recent years, zebrafish have been proposed as a model for rapid analysis of gene function and biological activity due to high genetic similarities with humans. The aim of this study was to determine the effects of overfeeding-induced diabetes w/o glucose on inflammatory cytokine as well as insulin and glucose transporter-2 genes (GLUT2) genes expression in the pancreas in zebrafish.

Materials and methods

The experiment was performed on 120 zebrafish (duplicated sample) with a specific genetic mapping (AB-Wild type). A total of 8 tanks, each containing 15 fish per 2-liter water, were used and divided into four groups: (1) Control group, (2) regular diet with glucose,3) Only Artemia overfeeding and 4) Combined Artemia with glucose. We induced T2DM zebrafish using glucose monohydrate solution in water and repeated daily Artemia feeding. In this model, fasting blood glucose increase is preceded by obesity and glucose intolerance. The experiment lasted for two months. Blood glucose and fish biometrics were measured in two steps. The expression of TNFα, IFNγ, GLUT2 and Insulin genes were quantified by a Real-Time qPCR System (Applied Biosystems, USA) using a set of specific primers.

Results

The highest mortality rate was observed in combined Artemia and glucose (p < 0.05). We showed significantly higher expression of IL-1B and TNF-α as well as inhibitory cytokines such as IFNγ genes in overfeeding induced diabetes(OID) which was highest in the combined Artemia and glucose group.(p < 0.05)The GLUT2 gene expression was higher in the pure artemia group which decreased to a lower level by adding glucose to Artemia in the diet. (p < 0.05). Also, the lowest insulin gene expression was observed in the combined group (p < 0.05).

Conclusions

In zebrafish, diabetes induction with overfeeding and supraphysiological glucose in diet accompanied with higher expression of inflammatory cytokines genes in the pancreas as well as lower insulin and GLU2 genes. These epigenetic factors appeared to initiate pancreatic beta dysfunction alongside insulin resistance and could have a crucial role in the pathogenesis of overfeeding-induced diabetes using primitive animal models.

Non-achievement of the Low-Density Lipoprotein Cholesterol Goal in Older Patients with Type 2 Diabetes Mellitus and a Very High Cardiovascular Disease Risk: A Multicenter Study in Vietnam

BACKGROUND

Lowering the low-density lipoprotein cholesterol (LDL-c) level is important for reducing cardiovascular (CV) events. However, little is known about the management of LDL-c in older patients with type 2 diabetes mellitus (T2DM). This study investigated the prevalence and factors associated with the non-achievement of LDL-c goals in older T2DM patients with a very high risk of CV diseases.

METHODS

This multicenter cross-sectional study measured the LDL-c levels of 733 T2DM outpatients from December 2019 to July 2020. The patients were aged ≥60 years, had very high risks of CV disease, and had been on LDL-c-lowering therapy for 6 months or more. The goal of lipid concentrations were assessed based on the recent guidelines of the European Society of Cardiology. We applied logistic regression analysis to identify the factors associated with the non-achievement of the LDL-c goal.

RESULTS

The mean age of the patients was 68.6±7.2 years. In total, 654 patients (89.2%) did not achieve the aggressive LDL-c goal of <1.4 mmol/L. In the adjusted model, the factors associated with the non-achievement of the LDL-c goal were obesity defined by body mass index (odds ratio [OR]=2.33; 95% confidence interval [CI], 1.13-4.81; p=0.022) and high-intensity statin therapy (OR=0.03; 95% CI, 0.01-0.05; p<0.001), while age, sex, education level, smoking habit, and comorbidities were not associated.

CONCLUSION

Older patients with T2DM who are at a very high CV disease risk are often unable to achieve their LDL-c goal. Obesity can increase the probability of not achieving the LDL-c goal, whereas high-intensity statin therapy can decrease this probability.

Changes in Glycemic Control Among Individuals With Diabetes Who Used a Personalized Digital Nutrition Platform: Longitudinal Study

BACKGROUND

Diabetes-related costs are the highest across all chronic conditions in the United States, with type 2 diabetes accounting for up to 95% of all cases of diabetes. A healthy diet is strongly associated with lowering glycated hemoglobin A_1c (HbA_1c) levels among individuals with diabetes, which can help curtail other health complications. Digital health platforms can offer critical support for improving diet and glycemic control among individuals with diabetes. Less is known about the characteristics of people with diabetes who use digital health platforms (specifically, a platform that integrates personalized healthy meal plans and food ordering) and changes in their HbA_1c levels.

OBJECTIVE

The aim of this study is to characterize Foodsmart users with diabetes and evaluate the longitudinal impact of Foodsmart-a personalized digital nutrition platform with meal planning, food ordering, and nutrition education features-on changes in HbA_1c levels.

METHODS

We retrospectively analyzed data collected from 643 adults with at least two self-reported HbA_1c entries in the Foodsmart platform between January 2016 and June 2021. Participants self-reported their HbA_1c levels, height, weight, health conditions, and diet in a 53-item food frequency questionnaire. Diabetes was defined as HbA_1c ≥6.5%. We analyzed distributions of characteristics by baseline diabetes status and examined the association of characteristics with the likelihood of having diabetes at baseline. To evaluate the change in HbA_1c levels among Foodsmart users, we calculated mean changes (absolute and percent) in HbA_1c among participants with diabetes and by length of follow-up. We also compared changes in HbA_1c and weight between participants with diabetes at baseline who achieved a normal HbA_1c level and those who did not.

RESULTS

We found that 43.5% (280/643) of the participants with at least two HbA_1c level entries had diabetes at baseline. Participants with diabetes at baseline were more likely to be male, have a higher weight and BMI, report high blood pressure, and have a poorer diet in comparison to participants without diabetes. Using a multivariable logistic regression model, we found that being male and obese were statistically significantly associated with baseline diabetes. Among participants with diabetes at baseline, HbA_1c was reduced, on average, by 0.46%. In addition, 21.4% (60/280) of participants with diabetes achieved a normal HbA_1c level (<6.5%) in their last HbA_1c level entry; this percentage increased with longer follow-up time (39% [7/18] at >24 months). In a sensitivity analysis, users with an HbA_1c ≥7.0% at baseline had an average absolute change of -0.62% and 31.2% (62/199) of these participants achieved HbA_1c levels of less than 7.0%.

CONCLUSIONS

This study assessed characteristics of individuals enrolled on the Foodsmart platform with HbA_1c levels and found that users with diabetes had lower HbA_1c levels over time and a sizable percentage of participants were successful in achieving normal levels.

Nutritional management of type 2 diabetes in subjects with obesity: an international guideline for clinical practice

Type 2 diabetes mellitus (T2DM) and obesity represent a global public health problem. Current nutritional recommendations focused on weight loss and overall dietary quality. However, there is no consensus on the optimal macronutrient composition of the diet, particularly for the long-term management of T2DM in subjects with obesity. An international panel of experts reviewed and critically appraised the updated literature published on the topic. This review primarily examines the evidence for areas of consensus and uncertainty about nutritional therapy in patients with T2DM and obesity. The aim of this article is to provide nutritional advice to manage these patients in clinical practice.

Lifestyle modification program, LIFE is LIGHT, in patients with type 2 diabetes mellitus and obesity: Results from a 48-week, multicenter, non-randomized, parallel-group, open-label study

BACKGROUND

Obesity is a potential risk factor for development of type 2 diabetes mellitus (T2DM). To achieve long-term weight reduction in patients with T2DM and obesity using comprehensive lifestyle management program (LMP).

MATERIALS AND METHODS

This 48-week interventional, multicenter, parallel-group, open-label study included patients aged ≥18 years with T2DM and a body mass index (BMI) of 27-40 kg/m2. The primary objective was to demonstrate a clinically significant weight reduction (≥5%) from baseline in intensive lifestyle modification (ILM) and standard treatment (ST) groups.

RESULTS

The ILM group (N = 100) received recommendations for dietary and physical activity, and behavioral counseling. The ST group (N = 30) was managed in accordance with routine T2DM clinical practice. The patients in ST group were older (60.6 ± 8.9 vs. 54.6 ± 10.2 years in ILM group); overall more than 60% were women. At Week 48, the mean reduction in body weight was 5.8% (95% confidence interval [CI]: -6.9, -4.6) and 1.2% (95% CI: -2.6, 0.2) (p < 0.001) in the ILM and ST group, respectively. At Week 48, a weight loss of ≥5% was achieved by 50% of patients in the ILM group versus 13.3% in the ST group (p = 0.002). The decreases in BMI, waist-to-hip ratio and glycated hemoglobin (HbA1c) was significantly greater in the ILM versus ST group with between-group differences of -1.63 (p ≤ 0.001), -0.03 (р ≤ 0.001) and -0.69% (p = 0.002), respectively.

CONCLUSION

A clinically significant weight reduction (≥5%) was demonstrated in patients with obesity and T2DM with use of a comprehensive LMP, along with improvements in BMI, waist-to-hip ratio, and HbA1c.

A Pilot Study of Intervention With a Mobile Application Visualizing the Macronutrient Content for Type 2 Diabetes at a Japanese Center

BACKGROUND

Estimating the nutritional content of food is essential for self-management in people with type 2 diabetes mellitus, but it is a difficult skill to learn. The aim of this study was to investigate how diabetes management was impacted by the ability of patients to search for items they ate from a database of 26,300 different foods, and to visualize nutritional intake using the Japanese mobile application (app) "Calomeal."

METHODS

This was a single-arm, single-center, pilot study. Eighteen outpatients with type 2 diabetes mellitus used the "Calomeal" app for 3 months. The primary endpoint was change in hemoglobin A1c (HbA1c). Secondary endpoints were changes in body weight (BW), lipid parameters, and quality of life scores.

RESULTS

The baseline characteristics of the study subjects were as follows: age: 53.4 ± 7.8 years; male/female ratio: 11/7; HbA1c: 7.9 (7.58 - 8.23)%; and body mass index (BMI): 25.17 (21.63 - 28.59) kg/m2. Significant reductions in HbA1c and BMI were observed over 3 months (HbA1c: 7.9 (7.58 - 8.23)% to 7.6 (7.3 - 8.23)%, P = 0.0410; BMI: 25.17 (21.63 - 28.59) to 24.54 (21.57 - 27.81) kg/m2, P = 0.0057). Reductions in HbA1c and BMI both correlated with decreased carbohydrate intake estimated by the mobile app.

CONCLUSIONS

Japanese patients who used their smartphones to visualize their nutritional intake using the "Calomeal" app demonstrated improved short-term glycemic control and BMI. Although the validity of the results should be tested in future randomized controlled trials, this approach may be a clinical option for improving self-management in Japanese patients with type 2 diabetes mellitus.

Effect of a Smartphone App on Weight Change and Metabolic Outcomes in Asian Adults With Type 2 Diabetes: A Randomized Clinical Trial

IMPORTANCE

Lifestyle interventions are effective in diabetes management, with smartphone apps that manage health data and dietary and exercise schedules gaining popularity. However, limited evidence from randomized clinical trials exists regarding the effectiveness of smartphone-based interventions among Asian adults with type 2 diabetes.

OBJECTIVE

To compare the effects of a culturally contextualized smartphone-based intervention with usual care on weight and metabolic outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial conducted at multiple primary care centers in Singapore included 305 adults with type 2 diabetes and body mass index (BMI) of 23 or greater who had literacy in English and smartphone access. Participants were recruited between October 3, 2017, and September 9, 2019, and were randomly assigned (1:1; stratified by gender, age, and BMI) to intervention (99 participants) or control (105 participants) groups. Participants' data were analyzed using intention-to-treat analysis.

INTERVENTIONS

Both control and intervention participants received diet and physical activity advice from a dietitian at a baseline face-to-face visit. Intervention participants additionally used a smartphone app to track weight, diet, physical activity, and blood glucose and then communicated with dietitians for 6 months.

MAIN OUTCOMES AND MEASURES

Primary outcome was change in body weight, while secondary outcomes were changes in hemoglobin A1c (HbA1c), fasting blood glucose, blood pressure, lipids, and diet. Post hoc analyses included glycemic changes in the subgroup with HbA1c levels of 8% or greater and diabetes medication changes.

RESULTS

Among the 204 randomized participants (mean [SD] age, 51.2 [9.7] years; 132 [64.7%] men), baseline mean (SD) BMI was 30.6 (4.3). Compared with the control group, intervention participants achieved significantly greater reductions in weight (mean [SD] change, -3.6 [4.7] kg vs -1.2 [3.6] kg) and HbA1c levels (mean [SD] change, -0.7% [1.2] vs -0.3% [1.0]), with a greater proportion having a reduction in diabetes medications (17 participants [23.3%] vs 4 participants [5.4%]) at 6 months. The intervention led to a greater HbA1c reduction among participants with HbA1c levels of 8% or higher (mean [SD] change, -1.8% [1.4] vs -1.0% [1.4]; P = .001). Intergroup differences favoring the intervention were also noted for fasting blood glucose, diastolic blood pressure, and dietary changes.

CONCLUSIONS AND RELEVANCE

In this study, a smartphone-based lifestyle intervention was more effective in achieving weight and glycemic reductions among Asian adults with type 2 diabetes compared with usual care, supporting the use of apps in lifestyle intervention delivery.

Policaptil Gel Retard in adult subjects with the metabolic syndrome: Efficacy, safety, and tolerability compared to metformin

BACKGROUND

Policaptil Gel Retard® (PGR), is a new macromolecule complex based on polysaccharides slowing the rate of carbohydrate and fat absorption. It proved to significantly reduce body weight, acanthosis nigricans expression, HbA1c levels, and glucose metabolism abnormalities in obese, hyper-insulinemic adolescents. No such data are available for adults.

AIM

to compare the effects of PGR vs. metformin in adult subjects with the Metabolic Syndrome (MS) and T2DM on a Low Glycemic Index diet.

SUBJECTS AND METHODS

This spontaneous clinical, longitudinal, single-blind, randomized study based on a per-protocol analysis enrolled 100 outpatients with MS and T2DM consecutively referring to our clinic for three months, and randomly assigned to either the active treatment (Group A:, 6 tablets/day) or the comparator (Group B: Metformin tablets, 1500-2000 mg/day in two divided doses during the two main meals, to minimize side effects) to be taken 30 min before each main meal in equally divided doses. Serum lipid profile, anthropometry, HOMA-IR index, and tolerability parameters were evaluated before and after a 6-month follow-up period.

RESULTS

all parameters improved at a similar rate in both groups but for the lipid profile, which got even better in Group A. Group A also experienced less prominent gastrointestinal side effects than its counterpart.

CONCLUSION

For the first time, we showed the non-inferiority of PGR compared to metformin in obese adult subjects with the MS and T2DM as for glycemic control and a clear-cut superiority of PGR in terms of both serum lipid-lowering capacity and tolerability.

Nutrition counseling is associated with less sarcopenia in diabetes: A cross-sectional and retrospective cohort study

OBJECTIVES

Muscle is crucial for blood glucose regulation. There is a need to prevent and treat sarcopenia in diabetes mellitus (DM). This study aimed to estimate the prevalence of sarcopenia and evaluate the association of nutritional counseling with the development of sarcopenia for people with DM.

METHODS

In a cross-sectional and retrospective cohort study, people with type 2 DM were recruited from the Diabetes Shared Care Program of a teaching hospital. Muscle mass, muscle strength, and physical functional performance were evaluated using the Asian Working Group for Sarcopenia criteria. The skeletal muscle mass index was determined by dividing muscle mass by the square of the height. Clinical information, including the nutrition counseling record, was retrospectively obtained from medical records for a 2-y period.

RESULTS

The prevalence of low skeletal muscle mass index (presarcopenia) and sarcopenia were, respectively, 20.4% and 9.6% (including 3.1% severe) among 1292 participants. Specifically, 15.3% of participants age ≥ 65 y were categorized as having sarcopenia. With more frequent nutritional counseling, there was a lesser risk of sarcopenia; the adjusted odds ratio (95% confidence interval) was 0.51 (0.27-0.94) for ≥ 3 times/2 y compared to no counseling. DM duration and age, glycemic status and medication, and body mass index and counseling frequency had no joint effects; however, these variables (except HbA1 c) were independent risk factors for low skeletal muscle mass index and sarcopenia.

CONCLUSIONS

People with type 2 DM have a high risk of sarcopenia. Increased nutrition counseling in outpatients was associated with less sarcopenia. Education about sarcopenia-associated risk factors should be encouraged early in the onset of DM.

A Novel Food Record App for Dietary Assessments Among Older Adults With Type 2 Diabetes: Development and Usability Study

Background

More than 1 in 4 people in the United States aged 65 years and older have type 2 diabetes. For diabetes care, medical nutrition therapy is recommended as a clinically effective intervention. Previous researchers have developed and validated dietary assessment methods using images of food items to improve the accuracy of self-reporting over traditional methods. Nevertheless, little is known about the usability of image-assisted dietary assessment methods for older adults with diabetes.

Objective

The aims of this study were (1) to create a food record app for dietary assessments (FRADA) that would support image-assisted dietary assessments, and (2) to evaluate the usability of FRADA for older adults with diabetes.

Methods

For the development of FRADA, we identified design principles that address the needs of older adults and implemented three fundamental tasks required for image-assisted dietary assessments: capturing, viewing, and transmitting images of food based on the design principles. For the usability assessment of FRADA, older adults aged 65 to 80 years (11 females and 3 males) were assigned to interact with FRADA in a lab-based setting. Participants’ opinions of FRADA and its usability were determined by a follow-up survey and interview. As an evaluation indicator of usability, the responses to the survey, including an after-scenario questionnaire, were analyzed. Qualitative data from the interviews confirmed the responses to the survey.

Results

We developed a smartphone app that enables older adults with diabetes to capture, view, and transmit images of food items they consumed. The findings of this study showed that FRADA and its instructions for capturing, viewing, and transmitting images of food items were usable for older adults with diabetes. The survey showed that participants found FRADA easy to use and would consider using FRADA daily. The analysis of the qualitative data from interviews revealed multiple categories, such as the usability of FRADA, potential benefits of using FRADA, potential features to be added to FRADA, and concerns of older adults with diabetes regarding interactions with FRADA.

Conclusions

This study demonstrates in a lab-based setting not only the usability of FRADA by older adults with diabetes but also potential opportunities using FRADA in real-world settings. The findings suggest implications for creating a smartphone app for an image-assisted dietary assessment. Future work still remains to evaluate the feasibility and validity of FRADA with multiple stakeholders, including older adults with diabetes and dietitians.
