Effect of Wearable Technology on Metabolic Control and the Quality of Life in Children and Adolescents with Type 1 Diabetes: A Systematic Review and Meta-Analysis

Background

Type 1 diabetes is one of the most common chronic diseases in children. Wearable technology (insulin pumps and continuous glucose monitoring devices) that makes diabetes management relatively simple, in addition to education and follow-ups, enhances the quality of life and health of individuals with diabetes.

Aims

To evaluate the impact of wearable technology on metabolic management and the quality of life in children and adolescents with type 1 diabetes.

Study Design

Systematic review and meta-analysis.

Methods

The Preferred Reporting System for Systematic Reviews and Meta-Analyses was used to conduct a systematic review and meta-analysis. PubMed, Web of Science, MEDLINE, Cochrane Library, EBSCO, Ulakbim and Google Scholar were searched in July 2022 and July 2023 using predetermined keywords. The methodological quality of the studies was evaluated using the Joanna Briggs Institute’s Critical Appraisal Checklists for randomized controlled experimental and cross-sectional studies. The meta-analysis method was used to pool the data.

Results

Eleven studies published between 2011 and 2022 were included. The total sample size of the included studies was 1,853. The meta-analysis revealed that the decrease in hemoglobin A1C (HbA1c) level in those using wearable technology was statistically significant [mean difference (MD): -0.33, Z = 2.54, p = 0.01]. However, the technology had no effect on the quality of life [standardized mean difference (SMD): 0.44, Z = 1.72, p = 0.09]. The subgroup analyses revealed that the decrease in the HbA1c level occurred in the cross-sectional studies (MD: -0.49, Z = 2.54, p = 0.01) and the 12-19 (MD = 0.59, Z = 4.40, p < 0.001) and 4-18 age groups (MD: -0.31, Z = 2.56, p = 0.01). The subgroup analyses regarding the quality of life revealed that there was no difference according to the research design. However, the quality of life was higher in the wearable technology group than in the control group in the 8-12 and 4-18 age groups (SMD: 1.32, Z = 2.31, p = 0.02 and SMD: 1.00, Z = 5.76, p < 0.001, respectively).

Conclusion

Wearable technology effectively reduces the HbA1c levels in children and adolescents with type 1 diabetes in some age groups. However, it does not affect the quality of life.

Telephone calls and glycemic control in type 2 diabetes: A PRISMA-compliant systematic review and meta-analysis of randomized clinical trials

AIMS

In-depth and updated systematic reviews evaluating telephone calls in type 2 diabetes (T2DM) management are missing. This study aimed to assess the effect of this intervention on glycemic control in T2DM patients when compared with usual care.

METHODS

We systematically searched for randomized controlled trials (RCT) on T2DM using Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and LILACS, up to March 2021. The Risk of Bias 2.0 (Rob 2.0) tool and GRADE were used for the quality evaluation. The intervention effect was estimated by the change in glycated hemoglobin (HbA1c). PROSPERO registry CRD42020204519.

RESULTS

3545 references were reviewed and 32 were included (8598 patients). Telephone calls, all approaching education, improved HbA1c by 0.33% [95% CI, -0.48% to -0.18%; I2 = 78%; p < 0.0001] compared to usual care. A greater improvement was found when the intervention included pharmacologic modification (-0.82%, 95% CI, -1.42% to -0.22%; I2 = 92%) and when it was applied by nurses (-0.53%, 95% CI, -0.86% to -0.2%; I2 = 87%). Meta-regression showed no relationship between DM duration and HbA1c changes.

CONCLUSION

The telephone call intervention provided a benefit regarding T2DM glycemic control, especially if provided by nurses, or if associated with patient education and pharmacological treatment modification.

Pichia pastoris Mediated Digestion of Water-Soluble Polysaccharides from Cress Seed Mucilage Produces Potent Antidiabetic Oligosaccharides

Diabetes mellitus is a heterogeneous metabolic disorder that poses significant health and economic challenges across the globe. Polysaccharides, found abundantly in edible plants, hold promise for managing diabetes by reducing blood glucose levels (BGL) and insulin resistance. However, most of these polysaccharides cannot be digested or absorbed directly by the human body. Here we report the production of antidiabetic oligosaccharides from cress seed mucilage polysaccharides using yeast fermentation. The water-soluble polysaccharides extracted from cress seed mucilage were precipitated using 75% ethanol and fermented with Pichia pastoris for different time intervals. The digested saccharides were fractionated through gel permeation chromatography using a Bio Gel P-10 column. Structural analysis of the oligosaccharide fractions revealed the presence of galacturonic acid, rhamnose, glucuronic acid, glucose and arabinose. Oligosaccharide fractions exhibited the potential to inhibit α-amylase and α-glucosidase enzymes in a dose-dependent manner in vitro. The fraction DF73 exhibited strong inhibitory activity against α-amylase with IC50 values of 38.2 ± 1.12 µg/mL, compared to the positive control, acarbose, having an IC50 value of 29.18 ± 1.76 µg/mL. Similarly, DF72 and DF73 showed the highest inhibition of α-glucosidase, with IC50 values of 9.26 ± 2.68 and 50.47 ± 5.18 µg/mL, respectively. In in vivo assays in streptozotocin (STZ)-induced diabetic mice, these oligosaccharides significantly reduced BGL and improved lipid profiles compared to the reference drug metformin. Histopathological observations of mouse livers indicated the cytoprotective effects of these sugars. Taken together, our results suggest that oligosaccharides produced through microbial digestion of polysaccharides extracted from cress seed mucilage have the potential to reduce blood glucose levels, possibly through inhibition of carbohydrate-digesting enzymes and regulation of the various signaling pathways.

AdultCarbQuiz for the Portuguese population with type 1 diabetes mellitus: translation, cultural adaptation and validation of its metabolic impact

AIMS

In type 1 diabetes mellitus (T1DM), functional insulin therapy, based on carbohydrate (CH) counting and individualized insulin-to-carbohydrate ratio, is essential to achieve an adequate metabolic control. However, to date, few tools have been validated to assess patients' knowledge about CH counting, with the AdultCarbQuiz questionnaire having proved to be a reliable method in an American cohort. The aim of this study was to translate, culturally adapt and validate the AdultCarbQuiz questionnaire for the Portuguese population.  METHODS: This was a cross-sectional study of patients with T1DM on functional insulin therapy through continuous subcutaneous insulin infusion (CSII). Prior to its application, the AdultCarbQuiz questionnaire was translated and culturally adapted to the Portuguese context. Statistical analyses include descriptive, correlation and intern consistency analysis using IBM® SPSS® Statistics, version 27.

RESULT

One hundred patients were included, 58% of female sex, with a mean age of 31.09 ± 10.77 years. Mean disease duration was 15.04 ± 9.23 years, and mean CSII usage time was 4.02 ± 3.90 years. The average value of glycated haemoglobin (HbA1c), time in range (TIR), time above range (TAR) and time below range was, respectively, 7.32 ± 0.87, 59.75 ± 14.13, 34.38 ± 15.40 and 5.75 ± 6.58%. The average score of the questionnaire was 30.86 points ± 3.58 points, considered high. The Kuder-Richardson 20 coefficient value was 0.63 for the total score, with a Spearman-Brown value for the half-split of 0.63. Individuals with lower HbA1c values scored significantly higher on knowledge about hypoglycaemia prevention and correction (r = - 0.269, p = 0.007) and on the total questionnaire score (r = - 0.205, p = 0.041). A higher TIR and a lower TAR were also associated with a higher total score (r = 0.274, p = 0.007 and r = - 0.274, p = 0.007, respectively).

CONCLUSIONS

In this study, the AdultCarbQuiz questionnaire, translated and culturally adapted to the Portuguese context, proved to be a useful tool in assessing knowledge about CH counting in patients with T1DM, allowing to optimize, individually, the therapeutic strategy in consultation.

Association Between Psychosocial Acuity and Glycemic Control in a Pediatric Type 1 Diabetes Clinic

PURPOSE

The purpose of this study was to describe the frequency of psychosocial risk and its associations with glycemic levels in youth with type 1 diabetes (T1D) seen by social work staff during regular clinical care.

METHODS

A retrospective longitudinal analysis of observational clinical data was conducted. Individuals (1-26 years) with known T1D who were seen at a pediatric diabetes clinic in a US academic medical center between 2014 and 2021 were included. Variables included psychosocial acuity, A1C, and demographic characteristics. Chi-square tests, Wilcoxon rank sum tests, and mixed linear regressions were used to examine associations between demographic variables, psychosocial acuity, and A1C.

RESULTS

Of 966 patients, 513 (53.1%) were male, 76 (7.9%) were non-Hispanic Black, and 804 (83.2%) were non-Hispanic White. There was a mean of 6.9 annual social work encounters per patient, with 3 psychosocial domains measured at each visit. Results showed that as psychosocial acuity level increased, glycemic control decreased. There were significant differences in A1C according to race/ethnicity, insurance, age, and psychosocial acuity.

CONCLUSIONS

In a real-world clinical population, psychosocial acuity was associated with glycemic control. Presenting for psychosocial issues in their diabetes clinic was associated with reduced glycemic control among youth with T1D. There is an opportunity to connect pediatric patients with appropriate mental health services and psychosocial supports.

Advances in secondary prevention mechanisms of macrovascular complications in type 2 diabetes mellitus patients: a comprehensive review

Type 2 diabetes mellitus (T2DM) poses a significant global health burden. This is particularly due to its macrovascular complications, such as coronary artery disease, peripheral vascular disease, and cerebrovascular disease, which have emerged as leading contributors to morbidity and mortality. This review comprehensively explores the pathophysiological mechanisms underlying these complications, protective strategies, and both existing and emerging secondary preventive measures. Furthermore, we delve into the applications of experimental models and methodologies in foundational research while also highlighting current research limitations and future directions. Specifically, we focus on the literature published post-2020 concerning the secondary prevention of macrovascular complications in patients with T2DM by conducting a targeted review of studies supported by robust evidence to offer a holistic perspective.

A 10-year retrospective cohort of diabetic patients in a large medical institution: Utilizing multiple machine learning models for diabetic kidney disease prediction

Objective

As the prevalence of diabetes steadily increases, the burden of diabetic kidney disease (DKD) is also intensifying. In response, we have utilized a 10-year diabetes cohort from our medical center to train machine learning-based models for predicting DKD and interpreting relevant factors.

Methods

Employing a large dataset from 73,101 hospitalized type 2 diabetes patients at The First Affiliated Hospital of Zhengzhou University, we analyzed demographic and medication data. Machine learning models, including XGBoost, CatBoost, LightGBM, Random Forest, AdaBoost, GBDT (gradient boosting decision tree), and SGD (stochastic gradient descent), were trained on these data, focusing on interpretability by SHAP. SHAP explains the output of the models by assigning an importance value to each feature for a particular prediction, enabling a clear understanding of how individual features influence the prediction outcomes.

Results

The XGBoost model achieved an area under the curve (AUC) of 0.95 and an area under the precision-recall curve (AUPR) of 0.76, while CatBoost recorded an AUC of 0.97 and an AUPR of 0.84. These results underscore the effectiveness of these models in predicting DKD in patients with type 2 diabetes.

Conclusions

This study provides a comprehensive approach for predicting DKD in patients with type 2 diabetes, employing machine learning techniques. The findings are crucial for the early detection and intervention of DKD, offering a roadmap for future research and healthcare strategies in diabetes management. Additionally, the presence of non-diabetic kidney diseases and diabetes with complications was identified as significant factors in the development of DKD.

Instruments for measuring self-management and self-care in geriatric patients - a scoping review

Introduction

With demographic changes, prioritizing effective care for geriatric patients to maintain functionality, independence, and quality of life is crucial. Well-developed self-management or self-care abilities, which can be maintained and improved through interventions, are of the utmost importance. To implement these interventions tailored and effectively, a thorough assessment of the individual's self-management and self-care abilities is required.

Objective

This scoping review aimed to identify self-management and self-care instruments suitable for geriatric patients, their underlying theories and definitions of self-management and self-care, and their similarities and differences in item content.

Methods

A systematic search of the PubMed and CINAHL databases was conducted to identify retrievable full-text articles published in English in the medical and nursing fields since the 1970s, which were validated on a sample with an average age of at least 70 years, used generic rather than disease-specific items, and addressed the broad range of self-management and self-care abilities.

Results

Of the 20 included articles, six instruments were identified that were based on different theories and offered varying definitions of self-management or self-care. Despite these differences, all emphasize empowered individuals taking an active role in their care. Most address actual behavior and abilities referring to lifestyle factors and (anticipated) adjustment behavior. However, crucial aspects, such as psychological factors, (instrumental) activities of daily living, and social environment are not fully addressed in these instruments, nor are the types of execution to which the items refer, such as wants, feelings, confidence, or attitudes.

Conclusion

To fully understand how geriatric patients implement daily self-management or self-care, a combination of instruments covering the important factors of self-management and self-care and addressing multiple types of item execution, such as behaviors, abilities, wants, or attitudes, is recommended. This review provides the first comprehensive overview of self-management and self-care instruments suitable for geriatric patients.

Molecular Targets and Mechanisms of Casein-Derived Tripeptides Ile-Pro-Pro and Val-Pro-Pro on Hepatic Glucose Metabolism

The objective of this study was to explore the molecular targets and mechanism of Ile-Pro-Pro (IPP) and Val-Pro-Pro (VPP) on regulating glucose metabolism in hepatic cells and their in vivo hypoglycemic activities in mice. Results showed that both IPP and VPP (600 μM) significantly enhanced the glucose consumption in HepG2 cells and primary hepatocytes (p < 0.05). They also regulated activities of glucose metabolizing enzymes and increased the protein expression of p-AKT and GLUT2 in HepG2 cells. IPP directly interacted with the insulin receptor (IR) to activate the insulin/AKT signaling pathway. The activity of VPP on glucose consumption was not attributed to IR binding, and 76 potential antidiabetic targets were predicted by similarity ensemble and shape similarity approaches. Among them, the AKT and MAPK signaling pathway, in which two hub genes AKT1 and MAPK4 existed, were evaluated to make major contributions to the activity of VPP on glucose consumption. Moreover, both IPP and VPP (300 μmol/kg) could significantly reduce the blood glucose levels in mice (p < 0.05), with blood glucose area under the curve dropping by approximately 19% ± 0.09 and 21% ± 0.11%, respectively. This study provides a new theoretical support for the development of IPP and VPP as functional foods to regulate glucose metabolic disorders.

A 5-structured visits multidisciplinary clinical care approach to optimize the care of patients with type 2 diabetes: a pilot study

Introduction

Multidisciplinary coordinated care has been associated with improvement of diabetes care.

Aim and methods

This is a retrospective cohort analysis aimed to assess the effect of application of the five-structured visits Multi-disciplinary Clinical Care Approach (FMCA) on each of T2DM control, complications and comorbidities. The patients' records were assessed for one year of regular diabetes care followed with a year after implementation of FMCA for patients attending the diabetes clinic at Zulekha hospital. The patients were divided according to HbA1c (cutoff 7%) at the end of the FMCA year of follow-up into a group of controlled and another group of uncontrolled diabetes designated CDM and UCDM, respectively.

Results

49% of patients were males and the mean age was 44.22 years. HbA1c levels, LDL and urinary albumin/creatinine ratio (UACR) showed a marked decrease among the patients after implementation of FMCA (P = 0.02, P = 0.04, P = 0.003, respectively). Compared with an increase in the atherosclerotic cardiovascular risk score (ASCVD) during the regular period, exposure to FMCA significantly decreased the cardiovascular risk score (0.17%, 11.41%, P = 0.001, P = 0.001, respectively). A self-management score was significantly higher in CDM patients. After a multivariate regression analysis of factors affecting DM control, we detected that baseline HbA1c, UACR, self-management score and hospital admission rate were the most important factors to predict diabetes control.

Conclusion

The implementation of FMCA has shown a significant improvement in clinical and humanistic aspects of individuals with T2DM with a better outcome, more control and less complications.

Bioequivalence of Reference and Biosimilar Preparations of Premixed Biphasic Insulin Aspart: A Comparative Clamp Study

Biphasic insulin aspart 30 is a premixed formulation containing a soluble fraction of insulin aspart (30%) and a protamine-crystallized fraction (70%) that was developed to combine the rapid-acting and prolonged advantages of commercially available insulins. The aim of this bioequivalence study was to compare the pharmacokinetics (PKs) of GP-bi-asp and Novo-bi-asp, and evaluate the pharmacodynamic (PD) properties as well as the safety of these drugs in the hyperinsulinemic euglycemic clamp (HEC) procedure. This was a phase 1, randomized, double-blind, 2-sequence, 2-period crossover study. Thirty-four male volunteers who met the inclusion criteria underwent the HEC procedure following a single subcutaneous injection of 0.4 IU/kg of either GP-bi-asp or Novo-bi-asp in the abdomen. After the treatment, the subjects' plasma glucose levels were monitored for 24 hours and the glucose infusion rate (GIR) was adjusted to maintain the target blood glucose level. The PD parameters were calculated using GIR values. Insulin aspart concentrations were measured in blood plasma using validated ELISA assays to evaluate the PK parameters of the investigated drugs. The 90% confidence intervals for the geometric mean ratios of PK (Cins and AUCins-T ) parameters of Gp-bi-asp and Novo-bi-asp were close to 100% and within the 80%-125% limits for establishing bioequivalence. The safety profiles of both drugs were also comparable.

The impact of neuropsychological functions on self-care/self-management of type 2 diabetes in middle-aged people: a scoping review and meta-analysis

INTRODUCTION

This study aimed to investigate the impact of neuropsychological functions on self-care/self-management in middle-aged individuals with type 2 diabetes (T2DM).

AREAS COVERED

A comprehensive literature search was conducted from January 2012 to April 2023 across multiple databases. Ten articles were included in the scoping review, and 3 articles were included in the meta-analysis. The findings consistently indicated an association between reduced neuropsychological functions and poor self-care/self-management in this population. Memory functions, executive functions, and other domains were found to be significantly related to self-care/self-management, including diet management, exercise, blood glucose monitoring, and foot care.

EXPERT OPINION

This study highlights the importance of considering neuropsychological factors in understanding and improving diabetes management outcomes. The findings underscore the need for comprehensive neuropsychological assessments and the development of targeted interventions to address specific vulnerable domains. Future research should focus on elucidating underlying mechanisms, addressing methodological inconsistencies, and exploring the effectiveness of interventions targeting neuropsychological impairments. Incorporating technology and personalized approaches into diabetes management can enhance self-care/self-management and clinical outcomes in individuals with T2DM.

Flattening the Playing Field for Treatment of Diabetic Kidney Disease

Diabetic kidney disease (DKD) remains a major health care issue and is beset with significant racial and ethnic disparities in regard to its incidence, progression, and complication rate. An individual's health is influenced strongly by an array of societal-level factors commonly called the social determinants of health. Among these, DKD is influenced highly by structured resources and opportunities, as well as an individual's socioeconomic status, health insurance status, access to care, education, health literacy, nutrition, green space exposure, level of trust in the medical community, and more. Health equity is considered a state in which everyone has a fair and just opportunity to attain his or her highest level of health. Conversely, health inequities are a consequence of a structured discriminatory system of inequitable allocation of social determinants of health. When this discriminatory system is race-based it is referred to as structural racism, which eventually leads to racial and ethnic health disparities. The further downstream sequela of structural racism, consciously or unconsciously, impacts health systems, providers, and patients, and can lead to disparities in DKD development, progression, and complications. In this article, we explore potential interventions at the societal, health system, and provider levels that can help flatten the playing field and reduce racial and ethnic disparities in DKD.

Programa de diabetes: improving diabetes care for undocumented immigrants using the Chronic Care Model at a free community clinic

AIMS

This study examined whether the Chronic Care Model can be successfully applied to improve health outcome measures for uninsured, undocumented immigrants with diabetes at a free, non-federally funded community clinic.

METHODS

Data were collected from 128 uninsured, undocumented immigrants enrolled in Programa de diabetes, a comprehensive diabetes program at People's Health Clinic based on the six core elements of the Chronic Care Model. All study participants self-identified by the Hispanic ethnicity. A longitudinal study design was used to compare baseline diabetic health measures with outcome data after patient program participation over a 12-month enrollment period. Linear mixed effect model was used to determine the patient specific change in HbA1C across time, controlling for gender, age, food insecurity, income level, diabetes type, and literacy. In addition, McNemar tests were conducted to compare the coverage of eye exams and statin use before and after program enrollment.

RESULTS

After program enrollment, individual specific change in HbA1C was expected to be - 0.201 [95% CI 0.244, - 0.158] % per month after controlling for baseline covariates. There were statistically significant improvements in both eye exam coverage (p < 0.01) and statin use (p < 0.01).

CONCLUSIONS

The Chronic Care Model can be successfully applied to improve health outcome measures at a free, non-federally funded community clinic among uninsured, undocumented immigrants, who identify by the Hispanic ethnicity and have the diagnosis of diabetes. Barriers to care including food insecurity, federal poverty level and illiteracy do not preclude glycemic control.

Impact of a multicomponent healthcare intervention on glycaemic control in subjects with poorly controlled type 2 diabetes: The INTEGRA study

AIM

To evaluate whether a specially designed multicomponent healthcare intervention improves glycaemic control in subjects with poorly controlled type 2 diabetes.

MATERIALS AND METHODS

A cluster, non-randomized, controlled, pragmatic trial in subjects from 11 primary care centres with type 2 diabetes and HbA1c of more than 9% (> 75 mmol/mol) was conducted. The intervention (N = 225 subjects) was professional and patient-centred, including a dedicated monographic visit that encouraged therapeutic intensification by physicians. The sham control (N = 181) was identical to that of the intervention group except that the dedicated visit was omitted. The primary outcome was to compare the reductions in HbA1c values between the groups at 12 months of follow-up.

RESULTS

The mean age at baseline was 59.5 years, mean diabetes duration was 10.7 years and mean HbA1c was 10.3% (89.0 mmol/mol). Patients in the intervention arm achieved significantly greater HbA1c reduction than those in the sham control group at 12 months (mean difference -0.62%, 95% CI = -0.2%, -1.04%; P = .002). A larger percentage of intervention participants achieved an HbA1c of less than 8% (44.8% vs. 25.5%; P = .003) and were more frequently treated with more than three antidiabetic therapies (14.4% vs. 3.5%; P = .0008). Intervention was the only variable associated with higher odds of HbA1c less than 8% (odds ratio = 2.52; 95% CI = 1.54-4.12; P < .001).

CONCLUSIONS

A multicomponent intervention including a dedicated visit oriented at reducing therapeutic inertia by primary care physicians can improve glycaemic control in poorly controlled patients with type 2 diabetes.

Glucagon-like peptide-1 receptor agonists as add-on therapy to insulin for type 1 diabetes mellitus

Background: To assess the efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) used as an adjunct to insulin therapy in adults with type 1 diabetes. Methods: A search of electronic databases (Medline, Embase, and the Cochrane Central Register of Controlled Trials) from 1 January 1950 to 23 May 2021 was conducted to find randomized controlled trials. The primary outcome was the change in HbA1c. Eight efficacy and six safety secondary endpoints were evaluated via meta-analysis. Weighted mean difference (WMD) and odds ratio (OR), alongside 95% confidence interval (CI), were calculated using the random effects model. Results: Among 1,379 candidate studies, 11 trials comprising 2,856 participants satisfied the inclusion criteria. Overall, GLP-1 RA adjunctive therapy reduced HbA1c by -0.21% (95% CI, -0.33 to -0.10), weight by -4.04 kg (-4.8 to -3.27), systolic pressure by -2.57 mmHg (-4.11 to -1.03), and diastolic blood pressure by -1.02 mmHg (-1.99 to -0.06). In addition, there was a decrease in prandial insulin dose (WMD, -4.23 IU; 95% CI, -5.26 to -3.20), basal insulin dose (-2.40 IU; -3.93 to -0.87), and total insulin dose (-5.73 IU; -10.61 to -0.86). Moreover, GLP-1 RAs did not increase the incidence of severe hypoglycemia, diabetic ketoacidosis, or severe adverse events. However, GLP-1 RAs increased the incidence of gastrointestinal adverse events (OR, 2.96; 95% CI, 2.33-3.77). Conclusion: Our meta-analysis of randomized clinical trials suggests moderate beneficial effects of GLP-1 RAs on the metabolic profile in patients with type 1 diabetes, without an increased risk of serious adverse events.

Improving Diabetes Care Through Population Health Innovations and Payments: Lessons from Western Maryland

BACKGROUND

Global budgets might incentivize healthcare systems to develop population health programs to prevent costly hospitalizations. In response to Maryland's all-payer global budget financing system, University of Pittsburgh Medical Center (UPMC) Western Maryland developed an outpatient care management center called the Center for Clinical Resources (CCR) to support high-risk patients with chronic disease.

OBJECTIVE

Evaluate the impact of the CCR on patient-reported, clinical, and resource utilization outcomes for high-risk rural patients with diabetes.

DESIGN

Observational cohort study.

PARTICIPANTS

One hundred forty-one adult patients with uncontrolled diabetes (HbA1c > 7%) and one or more social needs who were enrolled between 2018 and 2021.

INTERVENTIONS

Team-based interventions that provided interdisciplinary care coordination (e.g., diabetes care coordinators), social needs support (e.g., food delivery, benefits assistance), and patient education (e.g., nutritional counseling, peer support).

MAIN MEASURES

Patient-reported (e.g., quality of life, self-efficacy), clinical (e.g., HbA1c), and utilization outcomes (e.g., emergency department visits, hospitalizations).

KEY RESULTS

Patient-reported outcomes improved significantly at 12 months, including confidence in self-management, quality of life, and patient experience (56% response rate). No significant demographic differences were detected between patients with or without the 12-month survey response. Baseline mean HbA1c was 10.0% and decreased on average by 1.2 percentage points at 6 months, 1.4 points at 12 months, 1.5 points at 18 months, and 0.9 points at 24 and 30 months (P<0.001 at all timepoints). No significant changes were observed in blood pressure, low-density lipoprotein cholesterol, or weight. The annual all-cause hospitalization rate decreased by 11 percentage points (34 to 23%, P=0.01) and diabetes-related emergency department visits also decreased by 11 percentage points (14 to 3%, P=0.002) at 12 months.

CONCLUSIONS

CCR participation was associated with improved patient-reported outcomes, glycemic control, and hospital utilization for high-risk patients with diabetes. Payment arrangements like global budgets can support the development and sustainability of innovative diabetes care models.

Evaluation of Financial Conflicts of Interest and Quality of Evidence Underlying the American Diabetes Association Clinical Practice Guidelines: The Standards of Medical Care in Diabetes, 2021

BACKGROUND

Clinical practice guidelines make recommendations based on the best available evidence. Proper management and disclosure of financial conflicts of interest (FCOIs) are necessary for trustworthy clinical practice guidelines. This study evaluated the prevalence of FCOIs and quality of evidence underlying the American Diabetes Association (ADA) guidelines.

METHODS

Using the Open Payments Database (OPD) between 2018 and 2020, we examined the research and general payments to all authors of the Standards of Medical Care in Diabetes, 2021. The quality of evidence and tone of recommendations were assessed and the associations between the two were evaluated by logistic regression analysis.

RESULTS

Of the 25 guideline authors, 15 (60.0%) were United States (US)-based physicians eligible for the OPD search. Eight (32.0%) and 12 (48.0%) received one or more industry payments one year and three years prior to the guideline publication, respectively. The median total payments (interquartile range) per author were $33,262 ($4,638‒$101,271) in 2020 and $18,053 ($2,529‒$220,659) in 2018-2020. One author received a research payment of over $10,000 undeclared. Of 471 recommendations, 61 (13.0%) and 97 (20.6%) were supported by low-quality evidence and expert opinions, respectively. Also, 439 (93.2%) recommendations had a positive tone. The lower quality of evidence tended to recommend positively with an odds ratio of 1.56 (95% confidence interval: 0.96-2.56, p=0.075) without reaching statistical significance.

CONCLUSION

A minority of the guideline authors received industry payments from the healthcare industry, and declared FCOIs were mostly accurate. However, the ADA FCOI policy required the guideline authors to declare their FCOIs for one year before publication. A more transparent and rigorous FCOI policy is needed in the ADA guidelines.

Perspective: Acknowledging a Hierarchy of Social Needs in Diabetes Clinical Care and Prevention

The evidence of suboptimal social determinants of health (SDoH) on poor health outcomes has resulted in widespread calls for research to identify ways to measure and address social needs to improve health outcomes and reduce disparities. While assessing SDoH has become increasingly important in diabetes care and prevention research, little guidance has been offered on how to address suboptimal determinants in diabetes-related clinical care, prevention efforts, medical education and research. Not surprisingly, many patients experience multiple social needs - some that are more urgent (housing) than others (transportation/resources), therefore the order in which these needs are addressed needs to be considered in the context of diabetes care/outcomes. Here we discuss how conceptualizing diabetes related health through the lens of Maslow's hierarchy of needs has potential to help prioritize individual social needs that should be addressed to improve outcomes in the context of population-level determinants in the communities where people live.

Development and Implementation of Diabetes Care by a Community Network Based on a Chronic Care Model

INTRODUCTION

This participatory action research was conducted by the collaborative health-related team in a district, in Thailand. The community network jointly developed a care model for diabetic patients in primary care using the Chronic Care Model (CCM) and evaluated the effectiveness of implemented model.

METHODS

Data was collected between October 2021 and March 2022 and involved 2 groups: 1) a community network of 25 people including representatives of the community hospital, primary care hospital, Sub-district administrative organization, community leaders, community representatives, representatives of diabetic patients, and representatives of caregivers of diabetic patients, and 2) 41 people with type 2 diabetes and 41 of their family caregivers. The research was conducted in 4 stages: planning, action, observation, and reflection.

RESULTS

Both quantitative and qualitative data were collected, and the overall average knowledge scores of diabetic patients, family caregivers, and community representatives significantly increased from before (6.07 ± 2.11, 7.07 ± 1.98, P = .024, 5.74 ± 1.88, 7.37 ± 2.25, P < .001, 7.47 ± 2.44, 8.99 ± 1.72, P = .010) respectively. For satisfaction, diabetic patients were most satisfied with family caregiver support, while the community network representatives were most satisfied with their participation in planning a model for diabetic patients in primary care. After model implementation, the blood sugar-controlled patients (HbA1c < 7 mg%) significantly increased (0 and 9.76%, P = .045), although the fasting blood sugar (FBS) of diabetic patients did not improve.

CONCLUSION

The development and implementation of diabetes care based on CCM, promoted community participation and involvement in diabetes care. This model mainly affected diabetic patients who could control their HbA1c level and the satisfaction of the community network.

Ten-Year Effectiveness of the Multidisciplinary Risk Assessment and Management Programme-Diabetes Mellitus (RAMP-DM) on Macrovascular and Microvascular Complications and All-Cause Mortality: A Population-Based Cohort Study

OBJECTIVE

The Risk Assessment and Management Programme-Diabetes Mellitus (RAMP-DM) is a protocol-driven, risk-stratified, and individualized management program offered by a multidisciplinary team in addition to usual care for primary care patients with diabetes. This study aimed to evaluate the effectiveness of RAMP-DM for preventing complications and mortality over 10 years.

RESEARCH DESIGN AND METHODS

A population-based, prospective cohort study of adult patients with type 2 diabetes managed in the Hong Kong public primary health care system between 2009 and 2010 was conducted. RAMP-DM participants and usual care patients were matched using one-to-one propensity score matching and followed for 10 years. Risks of macrovascular and microvascular complications and all-cause mortality were estimated by Cox proportional hazards regression.

RESULTS

A total of 36,746 patients (18,373 in each group) were included after propensity score matching, with a median follow-up of 9.5 years and 306,802 person-years. RAMP-DM participants had significantly lower risks of macrovascular (hazard ratio [HR] 0.52, 95% CI 0.50-0.54) and microvascular (HR 0.68, 95% CI 0.64-0.72) complications and all-cause mortality (HR 0.45, 95% CI 0.43-0.47) than patients who received usual care only. However, the effect of RAMP-DM on macrovascular and microvascular complications attenuated after the 9th and 8th year of follow-up, respectively. RAMP-DM participants also showed better control of hemoglobin A1c, blood pressure, triglycerides, and BMI and a slower decline in renal function.

CONCLUSIONS

Significant reductions in diabetes-related complications and all-cause mortality were observed among RAMP-DM participants over a 10-year follow-up, yet the effect of preventing complications attenuated after 8 years.

Disease and debt: Findings from the 2019 Panel Study of Income Dynamics in the United States

Medical debt has grown dramatically over the past few decades. While cancer and diabetes are known to be associated with medical debt, little is known about the impact of other medical conditions and health behaviors on medical debt. We analyzed cross-sectional data on 9174 households - spanning lower-income, middle-income, and higher-income based on the Census poverty threshold - participating in the 2019 wave of the nationally representative United States Panel Study of Income Dynamics (PSID). The outcomes were presence of any medical debt and presence of medical debt≥ $2000. Respondents reported on medical conditions (diabetes, cancer, heart disease, chronic lung disease, asthma, arthritis, anxiety disorders, mood disorders) and on health behaviors (smoking, heavy drinking). Medical debt was observed in lower-income households with heart disease (OR = 2.64, p-value = 0.006) and anxiety disorders (OR = 2.16, p-value = 0.02); middle-income households with chronic lung disease (OR = 1.73, p-value = 0.03) and mood disorders (OR = 1.53, p-value = 0.04); and higher-income households with a current smoker (OR = 2.99, p-value<0.001). Additionally, medical debt ≥$2000 was observed in lower-income households with asthma (OR = 2.16, p-value = 0.009) and a current smoker (OR = 1.62, p-value = 0.04); middle income households with hypertension (OR = 1.65, p-value = 0.05). These novel findings suggest that the harms of medical debt extend beyond cancer, diabetes and beyond lower-income households. There is an urgent need for policy and health services interventions to address medical debt in a wider range of disease contexts than heretofore envisioned. Intervention development would benefit from novel conceptual frameworks on the causal relationships between health behaviors, health conditions, and medical debt that center social-ecological influences on all three of these domains.

South Asian ethnicity: What can we do to make this risk enhancer a risk equivalent?

South Asians account for around 25% of the global population and are the fastest-growing ethnicity in the US. This population has an increasing burden of atherosclerotic cardiovascular disease (ASCVD) which is also seen in the diaspora. Current risk prediction equations underestimate this risk and consider the South Asian ethnicity as a risk-enhancer among those with borderline-intermediate risk. In this review, we discuss why the South Asian population is at a higher risk of ASCVD and strategies to mitigate this increased risk.

A quasi-experimental study provides evidence that registered dietitian nutritionist care is aligned with the Academy of Nutrition and Dietetics evidence-based nutrition practice guidelines for type 1 and 2 diabetes

Background

One previous study examined implementation of evidence-based nutrition practice guidelines (EBNPG).

Objectives

To describe alignment of registered dietitian nutritionists' (RDNs) documented nutrition care with the Academy of Nutrition and Dietetics' EBNPG for Type 1 and Type 2 diabetes and examine impact of a midpoint training on care alignment with the guideline.

Methods

In this 2-year, quasi-experimental study, 19 RDNs providing outpatient medical nutrition therapy to adults with diabetes (n = 562) documented 787 initial and follow-up encounters. At study midpoint, RDNs received a guideline content training. A validated, automated tool was used to match standardized nutrition care process terminology (NCPT) in the documentation to NCPT expected to represent guideline implementation. A congruence score ranging from 0 (recommendation not identified) to 4 (recommendation fully implemented) was generated based on matching. Multilevel linear regression was used to examine pre-to-post training changes in congruence scores.

Results

Most patients (~75%) had only one documented RDN encounter. At least one guideline recommendation was fully implemented in 67% of encounters. The recommendations “individualize macronutrient composition” and “education on glucose monitoring” (partially or fully implemented in 85 and 79% of encounters, respectively) were most frequently implemented. The mean encounter congruence scores were not different from pre-to-post guideline training (n = 19 RDNs, 519 encounters pre-training; n = 14 RDNs, 204 encounters post-training; β = −0.06, SE = 0.04; 95% CI: −0.14, 0.03).

Conclusions

Most RDN encounters had documented evidence that at least one recommendation from the EBNPG was implemented. The most frequently implemented recommendations were related to improving glycemic control. A midpoint guideline training had no impact on alignment of care with the guideline.

Effect of the COVID-19 pandemic on glycemic control in Brazilian patients with type 2 diabetes

PURPOSE

To investigate the effect of restrictive measures the COVID-19 pandemic imposed on glycemic control of patients with type 2 diabetes (T2D) and its associated factors.

METHODS

Outpatients with T2D who had an appointment scheduled during the social distancing period were eligible for telemonitoring. Clinical and laboratorial data were collected from medical records in the last consultation before and from the first visit after the COVID-19 pandemic lockdown period.

RESULTS

From the 1241 eligible patients, 816 (65.7%) could be contacted by phone, 137 (11%) attended the unit for consultation during the social distancing period, and 1040 (83.8%) returned up to 12 months after the end of the lockdown period. We observed a meaningful reduction of glycated hemoglobin (HbA1c) (7.9 [7-9] vs. 7.7 [6.9-8.8] p = 0.004) and no difference in body mass index (29.5 [26-33.7] vs. 29.6 [26.2-34.1], p = 0.17) before and after the social distancing period. According to insulin use at baseline, the HbA1c variation was +0.6 (-0.7 to +2) and -0.6 (-2.1 to +0.7) in patients without and with insulin, respectively (p < 0.001). In the multivariate model, insulin therapy was the only independent significant predictor of HbA1c reduction.

CONCLUSION

This study observed an improvement in glycemic control after the lockdown. The only independent predictor found was previous insulin use. Probably, the longer time available to perform frequent blood glucose self-monitoring at home and adjustments in insulin therapy could explain our findings.

Assessment of quality of care provided to adults with type 2 diabetes mellitus at public hospitals in Gamo Gofa zone, Southern Ethiopia: Facility based Cross‐Sectional study

Purpose

Proactive management of type 2 diabetes is important for restoring beta‐cell function and improving sustained blood glucose control. Evidence on quality of diabetes care in Ethiopia is inadequate.

Method

Facility‐based cross‐sectional study was conducted to assess level of quality of care provided to adult type 2 diabetes patients at three public hospitals in Gamo Gofa Zone, Southern Ethiopia.

Results

A total of 210 adult type 2 diabetes patients were included. The mean age of patients was 44.1 ± 9.94 years. Fifty‐one (24.3%) of patients adhered to prescribed medicines. Sixty‐seven (31.9%) patients could benefit from neuropathy screening and referral. Diabetes‐specific evidence‐based guidelines, operational plan to reduce overweight and obesity were not available. There was no periodic lipid profile, renal function and glycated haemoglobin testing. Sixty‐three (30%) patients achieved fasting blood glucose (FBG) level. Only 41 (19.5%) achieved the recommended target value for composite intermediate outcomes. All three sub‐components of quality care structure, process and outcome (SPO) were below the agreed minimum score and the quality of care provided to adult type 2 diabetes was poor. Only 41 (19.5%) achieved agreed quality indicator targets for type 2 diabetes (fasting blood glucose blood pressure and low‐density lipoprotein cholesterol).

Conclusion

The quality of care provided to adult type 2 diabetes patients was poor particularly in areas such as availability of evidence‐based guidelines, operational plan to reduce obesity, monitoring of lipid profile and glycaemic control. Therefore, developing strategies for addressing structure, process and outcome‐related gaps by involving all stakeholders is critical for improving the quality of care provided to these patients.

Insulin: evolution of insulin formulations and their application in clinical practice over 100 years

The first preparation of insulin extracted from a pancreas and made suitable for use in humans after purification was achieved 100 years ago in Toronto, an epoch-making achievement, which has ultimately provided a life-giving treatment for millions of people worldwide. The earliest animal-derived formulations were short-acting and contained many impurities that caused adverse reactions, thereby limiting their therapeutic potential. However, since then, insulin production and purification improved with enhanced technologies, along with a full understanding of the insulin molecule structure. The availability of radio-immunoassays contributed to the unravelling of the physiology of glucose homeostasis, ultimately leading to the adoption of rational models of insulin replacement. The introduction of recombinant DNA technologies has since resulted in the era of both rapid- and long-acting human insulin analogues administered via the subcutaneous route which better mimic the physiology of insulin secretion, leading to the modern basal-bolus regimen. These advances, in combination with improved education and technologies for glucose monitoring, enable people with diabetes to better meet individual glycaemic goals with a lower risk of hypoglycaemia. While the prevalence of diabetes continues to rise globally, it is important to recognise the scientific endeavour that has led to insulin remaining the cornerstone of diabetes management, on the centenary of its first successful use in humans.

School Feeding as a Protective Factor against Insulin Resistance: The Study of Cardiovascular Risks in Adolescents (ERICA)

The objective of this study was to use ERICA data from adolescents from Brazilian public schools to investigate the role of school feeding in insulin resistance markers. Public school students (12-17 years old) with available biochemical examinations were selected. Adolescents answered a self-administered questionnaire, and contextual characteristics were obtained through interviews with principals. A multilevel mixed-effects generalized linear model was performed at the contextual and individual levels with each insulin resistance marker (fasting insulin, HOMA-IR, and blood glucose levels). A total of 27,990 adolescents were evaluated (50.2% female). The prevalence of (1) altered insulin was 12.2% (95% CI; 11.1, 13.5), (2) high HOMA-IR was 24.7% (95% CI; 22.8, 26.7), and (3) high blood glucose was 4.6% (95% CI; 3.8, 5.4). School feeding was positively associated with an insulin resistance marker, decreasing by 0.135 units of HOMA-IR (95% CI; -0.19, -0.08), 0.469 μU/L of insulin levels (95% CI; -0.66, -0.28), and 0.634 mg/dL of blood glucose (95% CI; -0.87, -0.39). In turn, buying food increased blood glucose by 0.455 mg/dL (95% CI; 0.16, 0.75). School feeding was positively associated with insulin resistance variables, demonstrating the potential of planned meals in the school environment to serve as a health promoter for the adolescent population.

Diabetes self-management and its associated factors among patients with diabetes in central Vietnam: A cross-sectional study

Objective

Diabetes self-management (DSM) enables maintenance of optimal individualized glycemic control for patients with diabetes through comprehensive lifestyle, medication adherence, and self-monitoring glucose level. This study aimed to evaluate DSM and to find associated factors among Vietnamese diabetes patients by using the Vietnamese version of Diabetes Self-Management Instrument (DSMI).

Methods

A cross-sectional study was conducted at a single hospital in the central Vietnam. DSM was assessed using the DSMI. The participant’s socio-demographic and clinical features were obtained through face-to-face interviews and medical records. Multivariate linear regression was used to determine independent factors associated with total DSMI.

Results

The mean total DSM score based on DSMI self-administered questionnaire scores was 88.4 ± 22.1, with a range of 47 to 140. The mean self-integration, self-regulation, interaction with health professionals, self-monitoring blood glucose, and adherence to the prescribed regime were 24.8, 22.3, 21.6, 10.2, and 9.5, respectively. 48.1% of DM patients had good HbA1c control. Sex, educational status, BMI, waist circumference, medical nutrition therapy, and sufficient physical activities were factors independently predictive of DSMI total score.

Conclusion

This study emphasizes that the DSM situation is seen to be average among DM patients with mean DSMI score 88.4 ± 22.1 and sex, educational status, BMI, waist circumference, medical nutrition therapy, and sufficient physical activities were independently predictive factors of DSMI total score. This evidence suggests that there is a need to enhance the effectiveness of DSM education programs among diabetic patients.

Associations Between DNA Methylation Age Acceleration, Depressive Symptoms, and Cardiometabolic Traits in African American Mothers From the InterGEN Study

Background

African American women (AAW) have a high risk of both cardiometabolic (CM) illness and depressive symptoms. Depressive symptoms co-occur in individuals with CM illness at higher rates than the general population, and accelerated aging may explain this. In this secondary analysis, we examined associations between age acceleration; depressive symptoms; and CM traits (hypertension, diabetes mellitus [DM], and obesity) in a cohort of AAW.

Methods

Genomic and clinical data from the InterGEN cohort (n = 227) were used. Age acceleration was based on the Horvath method of DNA methylation (DNAm) age estimation. Accordingly, DNAm age acceleration (DNAm AA) was defined as the residuals from a linear regression of DNAm age on chronological age. Spearman's correlations, linear and logistic regression examined associations between DNAm AA, depressive symptoms, and CM traits.

Results

DNAm AA did not associate with total depressive symptom scores. DNAm AA correlated with specific symptoms including self-disgust/self-hate (-0.13, 95% CI -0.26, -0.01); difficulty with making decisions (-0.15, 95% CI -0.28, -0.02); and worry over physical health (0.15, 95% CI 0.02, 0.28), but were not statistically significant after multiple comparison correction. DNAm AA associated with obesity (0.08, 95% CI 1.02, 1.16), hypertension (0.08, 95% CI 1.01, 1.17), and DM (0.20, 95% CI 1.09, 1.40), after adjustment for potential confounders.

Conclusions

Associations between age acceleration and depressive symptoms may be highly nuanced and dependent on study design contexts. Factors other than age acceleration may explain the connection between depressive symptoms and CM traits. AAW with CM traits may be at increased risk of accelerated aging.

SGLT2 Inhibitors and the Risk of Acute Kidney Injury in Older Adults With Type 2 Diabetes

RATIONALE & OBJECTIVE

Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been found to have many benefits for patients with type 2 diabetes. However, whether SGLT2 inhibitors increase the risk of acute kidney injury (AKI) remains unknown. We examined the association of AKI hospitalization with prior initiation of an SGLT2 inhibitor compared with initiation of a dipeptidyl peptidase 4 (DPP-4) inhibitor or a glucagon-like peptide 1 receptor agonist (GLP-1RA) among older adults with type 2 diabetes in routine practice.

STUDY DESIGN

Population-based cohort study.

SETTING & PARTICIPANTS

Older adults aged at least 66 years with type 2 diabetes enrolled in Medicare fee-for-service and who were new users of SGLT2 inhibitor, DPP-4 inhibitor, or GLP-1RA agents in the interval from March 2013 to December 2017.

EXPOSURES

New use of an SGLT2 inhibitor versus new use of a DPP-4 inhibitor or GLP-1RA.

OUTCOME

The primary outcome was hospitalization for AKI, defined as a discharge diagnosis of AKI in the primary or secondary position.

ANALYTICAL APPROACH

New users of SGLT2 inhibitors were matched at a 1:1 ratio to new users of DPP-4 inhibitors or GLP-1RAs using propensity scores in 2 pairwise comparisons. Cox proportional hazards regression models generated hazard ratios (HRs) with 95% CIs in propensity score-matched groups.

RESULTS

Totals of 68,130 and 71,477 new users of SGLT2 inhibitors were matched to new users of DPP-4 inhibitors or GLP-1RAs, respectively. Overall, the mean age of study participants was 72 years. The risk of AKI was lower in the SGLT2 inhibitor group than in the DPP-4 inhibitor group (HR, 0.71 [95% CI, 0.65-0.76]) or the GLP-1RA group (HR, 0.81 [95% CI, 0.75-0.87]).

LIMITATIONS

Residual confounding and lack of laboratory data.

CONCLUSIONS

Among older adults with type 2 diabetes, initiation of an SGLT2 inhibitor was associated with a reduced risk of AKI compared with initiation of a DPP-4 inhibitor or a GLP-1RA.

Effectiveness of restricted diet with a plate in patients with type 2 diabetes: A randomized controlled trial

BACKGROUND

In view of the complexity of dietary and nutritional education for most patients with type 2 diabetes mellitus (T2DM), a simplified approach called the "restricted diet with a plate" or "plate model" is recommended.

PURPOSE

To evaluate whether the plate model can effectively improve glycemic control and cardiovascular risk markers in type 2 diabetes mellitus (T2DM), while reducing the time devoted to education and avoiding weight gain.

METHODS

The study was a randomized, multicenter, controlled study, conducted between October 2018 and October 2019, among patients with T2DM living in Nanjing. The study included 419 participants who were randomly divided into a plate group and a counting group. The plate model included three components: a low-literacy, color leaflet containing the explanation and composition of the plate model, health education, and medical visits. Patients in the counting group received health education, group medical visits, and a paper booklet containing traditional carbohydrate counting education. Primary outcomes were glycemic control and weight.

RESULTS

Participants in the plate model reduced HbA_1c by 0.7% in the first three months, and reduced to a greater extent at six months (1.44%), but this was not sustained, and HbA_1c increased slightly over the following six months. Fasting plasma glucose (FPG) and 2-h postprandial glucose (2hPG) values were significantly reduced at the endpoint in the plate model (9.25 ± 1.72% vs. 7.44 ± 0.88%, P = 0.008; 12.07 ± 2.94 vs. 8.35 ± 1.99%; P = 0.004); however, the 2hPG values decreased most significantly. Total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels decreased significantly in the plate group, which occurred at six months and lasted for 12 months. In the first three months, the average weight loss in the plate group was 1.2 kg/month (95% CI 0.92-1.48), and in the fourth to twelfth months, the average weight gain was 0.21 kg/month (95% CI 0.08-0.34). There was significant difference in education time between the groups (17.3 ± 4.42 vs. 38.6 ± 12.63; P < 0.001).

CONCLUSIONS

The plate model is at least as effective as the counting model over the short term for glycemic control and perhaps even better for weight and lipid control. Plate model has the potential to improve education of those with low health literacy by reducing reading demands.

"No-one realises what we go through as Type 1s": A qualitative photo-elicitation study on coping with diabetes

AIMS

Type 1 diabetes (T1D) has physical, emotional, and social consequences and little is known how adults cope with the condition long term. This research aimed to use a novel photo-elicitation technique to gain in-depth insight into the personal coping experiences of adults living with T1D.

METHODS

In-depth photo elicitation interviews were employed to collect data and transcripts were analysed using thematic analysis.

RESULTS

Participant-led data revealed an overarching theme of the relentlessness of the condition. Continuous self-management tasks infiltrated participants' lives and had a significant impact on coping experiences. A range of techniques and resources were used to cope including using alarms and reminders, diabetes technology, interpersonal relationships, supportive healthcare services and seeking a mind-body balance.

CONCLUSIONS

Technology shows promise for easing the burden of the condition, expert-led online support would be of benefit, and peer support should be prioritised within interventions for adults with T1D.

Metabolic Syndrome Among American Indian and Alaska Native Populations: Implications for Cardiovascular Health

PURPOSE OF REVIEW

The latest national data reports a 55% prevalence of metabolic syndrome in American Indian adults compared to 34.7% of the general US adult population. Metabolic syndrome is a strong predictor for diabetes, which is the leading cause of heart disease in American Indian and Alaska Native populations. Metabolic syndrome and associated risk factors disproportionately impact this population. We describe the presentation, etiology, and roles of structural racism and social determinants of health on metabolic syndrome.

RECENT FINDINGS

Much of what is known about metabolic syndrome in American Indian and Alaska Native populations comes from the Strong Heart Study as there is scant literature. American Indian and Alaska Native adults have an increased propensity towards metabolic syndrome as they are 1.1 times more likely to have high blood pressure, approximately three times more likely to have diabetes, and have higher rates of obesity compared with their non-Hispanic White counterparts. Culturally informed lifestyle and behavior interventions are promising approaches to address structural racism and social determinants of health that highly influence factors contributing to these rates. Among American Indian and Alaska Native populations, there is scarce updated literature evaluating the underlying causes of major risk factors for metabolic syndrome, and progression to cardiometabolic disease. As a result, the actual state of metabolic syndrome in this population is not well understood. Systemic and structural changes must occur to address the root causes of these disparities.

Impact of sports participation on components of metabolic syndrome in adolescents: ABCD growth study

OBJECTIVES

This study aimed to analyze the impact of sports participation (12 months of practice) on the components of metabolic syndrome (MetS) in both sexes.

METHODS

This is an observational longitudinal study, a part of which is entitled "Analysis of Behaviors of Children During Growth" (ABCD Growth Study), Presidente Prudente, São Paulo, Brazil. The sample was composed of 171 adolescents (112 boys and 59 girls), divided into non-sports and sports groups. High-density lipoprotein-cholesterol (HDL-c), triglycerides, and glucose were analyzed by the colorimetric method of dry chemistry and processed biochemically. Systolic blood pressure and diastolic blood pressure were measured using an automatic device. Body fat was estimated using a densitometry scanner.

RESULTS

Adolescents who practiced sports were younger (p-value=0.001) and had a lower peak height velocity (p-value=0.001) than the non-sports group. The differences (Δ) after 12 months were of greater magnitude for the sports group when compared to the non-sports group (p-value=0.013), glucose (moderate magnitude in favor of the sports group; p-value=0.001), HDL-c (small magnitude in favor of the sports group; p-value=0.0015), and MetS (moderate magnitude in favor of the sports group; p-value=0.001).

CONCLUSIONS

The practice of sports in adolescents had a protective effect on the metabolic components of MetS.

Newly Diagnosed Type 2 Diabetes Care between Family Physicians, Endocrinologists, and Other Internists in Taiwan: A Retrospective Population-Based Cohort Study

(1) Background: We aimed to determine whether physicians of different specialties perform differently in the monitoring, cost control, and prevention of acute outcomes in diabetes care. (2) Methods: Using data from the Health and Welfare Data Science Center, participants with newly diagnosed type 2 diabetes (n = 206,819) were classified into three cohorts based on their primary care physician during the first year of diagnosis: family medicine (FM), endocrinologist, and other internal medicine (IM). The three cohorts were matched in a pairwise manner (FM (n = 28,269) vs. IM (n = 28,269); FM (n = 23,407) vs. endocrinologist (n = 23,407); IM (n = 43,693) vs. endocrinologist (n = 43,693)) and evaluated for process indicators, expenditure on diabetes care, and incidence of acute complications (using subdistribution hazard ratio; sHR). (3) Results: Compared to the FM cohort, both the IM (sHR, 1.26; 95% CI, 1.08 to 1.47) and endocrinologist cohorts (sHR, 1.57; 95% CI, 1.38−1.78) had higher incidences of acute complications. The FM cohort incurred lower costs than the IM cohort (USD 487.41 vs. USD 507.67, p = 0.01) and expended less than half of the diabetes-related costs of the endocrinology cohort (USD 484.39 vs. USD 927.85, p < 0.001). (4) Conclusion: Family physicians may provide better care at a lower cost to newly diagnosed type 2 diabetes patients. Relatively higher costs incurred by other internists and endocrinologists in the process of diabetes care may be explained by the more frequent ordering of specialized tests.

'I need someone to believe in me and walk the journey with me': A qualitative analysis of preferred approaches to weight management discussions in clinical care among adults with type 2 diabetes

AIMS

To explore the preferences of adults with type 2 diabetes regarding the approach to weight management discussions in clinical care.

METHODS

Online survey of Australian adults with type 2 diabetes, recruited via a national diabetes registry. Three open-ended questions explored participants' experiences and ideal approach to discussing weight management with health professionals. Data subjected to inductive thematic template analysis.

RESULTS

Participants were 254 adults, 58% aged 60+ years, 52% women and 35% insulin-treated. Five themes were developed to categorise participants' preferences for, as well as differing experiences of, weight management discussions: (1) collaborative, person-centred care: working together to make decisions and achieve outcomes, taking personal context into consideration; (2) balanced communication: open, clear messages encouraging action, empathy and kindness; (3) quality advice: knowledgeable health professionals, providing specific details or instructions; (4) weight management intervention: suitable modalities to address weight management and (5) system-wide support: referral and access to appropriate multi-disciplinary care.

CONCLUSIONS

Participants expressed preferences for discussing weight management in collaborative, person-centred consultations, with quality advice and personalised interventions across the health system, delivered with empathy. By adopting these recommendations, health professionals may build constructive partnerships with adults with type 2 diabetes and foster weight management.

Type 1 diabetes and the challenges of emotional support in crisis situations: results from a randomized clinical trial of a multidisciplinary teleintervention

The association between type 1 diabetes and mental health disorders could be exacerbated in a stressful environment. This study aimed to evaluate the effectiveness of a teleguided intervention on emotional disorders in patients with type 1 diabetes during the COVID-19 outbreak. An open-label clinical trial was performed during the social distancing period in the COVID-19 outbreak in Brazil. Individuals with type 1 diabetes aged ≥ 18 years were randomized to receive a teleguided multidisciplinary intervention or the usual care plus an educational website access. The primary outcome was a positive screening for emotional disorders (Self Report Questionnaire 20) after a 16-week intervention. Secondary outcomes included evaluation of patients' perceptions of pandemic-related changes, diabetes-related emotional distress, eating disorders, and sleep disorders. Data were analyzed with the intent-to-treat principle. Fifty-eight individuals (mean age, 43.8 ± 13.6 years) were included (intervention group, n = 29; control group, n = 29). The primary outcome was not different between the groups. The intervention group felt more supported in their diabetes care during the social distancing period (82.8% vs. 48.3% in the control group, P < 0.01). Both groups reported a similar self-perceived worsening of physical activity habits and mental health during the outbreak. There was no benefit to using the telehealth strategy proposed for emotional disorders in patients with type 1 diabetes during the COVID-19 outbreak. Further studies are needed to determine the impact on metabolic parameters and to understand why it is so difficult to emotionally support these patients.Trail Registration: ClinicalTrials.gov (NCT04344210), 14/04/2020.

2022 National Standards for Diabetes Self-Management Education and Support

PURPOSE

The National Standards for Diabetes Self-Management Education and Support (DSMES) provide guidance and evidence-based, quality practice for all DSMES services. Due to the dynamic nature of health care and diabetes research, the National Standards are reviewed and revised approximately every 5 years by key stakeholders and experts within the diabetes care and education community. For each revision, the Task Force is charged with reviewing the current National Standards for appropriateness, relevance, and scientific basis and making updates based on current evidence and expert consensus. In 2021, the group was tasked with reducing administrative burden related to DSMES implementation across diverse care settings.

CONCLUSION

The evidence supporting the 2022 National Standards clearly identifies the need to provide person-centered services that embrace cultural differences, social determinants of health, and the ever-increasing technological engagement platforms and systems. Payers are invited to review the National Standards as a tool to inform and modernize DSMES reimbursement requirements and to align with the evolving needs of people with diabetes (PWD) and physicians/other qualified health care professionals. The American Diabetes Association and the Association of Diabetes Care & Education Specialists strongly advocate for health equity to ensure all PWD have access to this critical service proven to improve outcomes both related to and beyond diabetes. The 2022 National Standards update is meant to be a universal document that is easy to understand and can be implemented by the entire health care community. DSMES teams in collaboration with primary care have been shown to be the most effective approach to overcome therapeutic inertia.

Relationship between housing insecurity, diabetes processes of care, and self-care behaviors

Background

The aim of this analysis was to examine the influence of housing insecurity on diabetes processes of care and self-care behaviors and determine if that relationship varied by employment status or race/ethnicity.

Methods

Using nationally representative data from the Behavioral Risk Factor Surveillance System (2014-2015), 16,091 individuals were analyzed for the cross-sectional study. Housing insecurity was defined as how often respondents reported being worried or stressed about having enough money to pay rent/mortgage. Following unadjusted logistic models testing interactions between housing insecurity and either employment or race/ethnicity on diabetes processes of care and self-care behaviors, stratified models were adjusted for demographics, socioeconomic status, health insurance status, and comorbidity count.

Results

38.1% of adults with diabetes reported housing insecurity. Those reporting housing insecurity who were employed were less likely to have a physicians visit (0.58, 95%CI 0.37,0.92), A1c check (0.45, 95%CI 0.26,0.78), and eye exam (0.61, 95%CI 0.44,0.83), while unemployed individuals were less likely to have a flu vaccine (0.84, 95%CI 0.70,0.99). Housing insecure White adults were less likely to receive an eye exam (0.67, 95%CI 0.54,0.83), flu vaccine (0.84, 95%CI 0.71,0.99) or engage in physical activity (0.82, 95%CI 0.69,0.96), while housing insecure Non-Hispanic Black adults were less likely to have a physicians visit (0.56, 95%CI 0.32,0.99).

Conclusions

Housing insecurity had an influence on diabetes processes of care and self-care behaviors, and this relationship varied by employment status and race/ethnicity. Diabetes interventions should incorporate discussion surrounding housing insecurity and consider differences in the impact by demographic factors on diabetes care.

Barriers to Prevention and Treatment of Type 2 Diabetes Mellitus Among Outpatients in Belarus

Objectives

This study aimed to determine the main barriers and reasons for non-adherence to preventive measures and treatment for type 2 diabetes mellitus among outpatients in Belarus.

Methods

An anonymous questionnaire survey was conducted with 814 adults aged 18 years and over who visited outpatient health care units and hospitals in Belarus. The questionnaire was developed to analyze the perceived barriers that limit adherence to preventive measures and treatment for type 2 diabetes.

Results

The proportion of respondents who reported doing daily physical activity was 53.2%, and 46.6% consumed at least 400 grams of fruit and vegetables per day. Among the 42.8% of respondents with a prescribed treatment for type 2 diabetes mellitus, 50.1% sometimes forgot to take their medicine. The specific barriers to treatment most frequently identified by survey respondents were "Financial situation" (23.5% of respondents), and "Fear of side effects" (25.2%). Those for lifestyle instructions were "Insufficient knowledge" (29.3%), "Financial situation" (27.9%), and "Lack of motivation" (21.7%).

Conclusions

The study revealed that the main barriers to adherence were insufficient knowledge of diabetes and its treatment and an underestimation of the role of behavioral risk factors in health, combined with financial difficulties. We recommend that physicians should take a patient-centered approach to raising awareness of behavioral risk factors for type 2 diabetes mellitus, and suggest that the importance of adhering to preventative measures and treatment should be promoted in consultations in Belarus.

Effects of PPARD gene variants on the therapeutic responses to exenatide in chinese patients with type 2 diabetes mellitus

BACKGROUND

Exenatide is a GLP-1R agonist that often exhibits considerable interindividual variability in therapeutic efficacy. However, there is no evidence about the impact of genetic variants in the PPARD on the therapeutic efficacy of exenatide. This research was aimed to explore the influence of PPARD gene polymorphism on the therapeutic effect of exenatide, and to identify the potential mechanism futher.

METHODS

A total of 300 patients with T2DM and 200 control subjects were enrolled to identify PPARD rs2016520 and rs3777744 genotypes. A prospective clinical study was used to collect clinical indicators and peripheral blood of T2DM patients treated with exenatide monotherapy for 6 months. The SNaPshot method was used to identify PPARD rs2016520 and rs3777744 genotypes, and then we performed correlation analysis between PPARD gene variants and the efficacy of exenatide, and conducted multiple linear regression analysis of factors affecting the therapeutic effect of exenatide. HepG2 cells were incubated with exenatide in the absence or presence of a PPARδ agonist or the siPPARδ plasmid, after which the levels of GLP-1R and the ratio of glucose uptake were determined.

RESULTS

After 6 months exenatide monotherapy, we observed that homeostasis model assessment for insulin resistance (HOMA-IR) levels of the subjects with at least one C allele of the PPARD rs2016520 were significantly lower than those with the TT genotype, which suggested that the PPARD rs2016520 TT genotype conferred the poor exenatide response through a reduction of insulin resistance, as measured by HOMA-IR. The carriers of G alleles at rs3777744 exhibited higher levels of in waist to hip ratio (WHR), fasting plasma glucose (FPG), hemoglobin A1c (HbA1c) and HOMA-IR compared to individuals with the AA genotype following 6 months of exenatide treatment, potentially accounting for the lower failure rate of exenatide therapy among the AA homozygotes. In an insulin resistant HepG2 cell model, the PPARδ agonists enhanced exenatide efficacy on insulin resistance, with the expression of GLP-1R being up-regulated markedly.

CONCLUSION

These data suggest that the PPARD rs2016520 and rs3777744 polymorphisms are associated with exenatide monotherapy efficacy, due to the pivotal role of PPARδ in regulating insulin resistance through affecting the expression of GLP-1R. This study was registered in the Chinese Clinical Trial Register (No. ChiCTR-CCC13003536).

The cGAS-STING pathway: more than fighting against viruses and cancer

In the classic Cyclic guanosine monophosphate–adenosine monophosphate (cGAMP) synthase (cGAS)-stimulator of interferon genes (STING) pathway, downstream signals can control the production of type I interferon and nuclear factor kappa-light-chain-enhancer of activated B cells to promote the activation of pro-inflammatory molecules, which are mainly induced during antiviral responses. However, with progress in this area of research, studies focused on autoimmune diseases and chronic inflammatory conditions that may be relevant to cGAS–STING pathways have been conducted. This review mainly highlights the functions of the cGAS–STING pathway in chronic inflammatory diseases. Importantly, the cGAS–STING pathway has a major impact on lipid metabolism. Different research groups have confirmed that the cGAS–STING pathway plays an important role in the chronic inflammatory status in various organs. However, this pathway has not been studied in depth in diabetes and diabetes-related complications. Current research on the cGAS–STING pathway has shown that the targeted therapy of diseases that may be caused by inflammation via the cGAS–STING pathway has promising outcomes.
