“An Ounce of Prevention”: A Primary Care Based Prevention Program for Pre-Diabetic Population

Examining the Effectiveness of an E-Learning Training Course for Coaches of a Type 2 Diabetes Prevention Program

Small Steps for Big Changes (SSBC) is a community-based diabetes prevention program (DPP). SSBC utilizes a motivational interviewing (MI) informed counseling style to deliver a structured diet and exercise curriculum to empower healthy behavioral modifications and prevent type 2 diabetes (T2D). An electronic learning (e-learning) platform to train SSBC coaches was developed to improve flexibility, reach, and accessibility. While e-learning has shown to be an effective mode of teaching content to health professionals, less is known in the context of DPP coaches. This study aimed to assess the effectiveness of the SSBC e-learning course. Twenty coaches (eleven fitness staff personnel and nine university students) were recruited through existing fitness facilities to participate in the online SSBC coach training which included completing pre- and post-training questionnaires, seven online modules of content and a mock client session. Knowledge regarding MI (Mpre = 3.30 ± 1.95, Mpost = 5.90 ± 1.29; p < 0.01), SSBC content (Mpre = 5.15 ± 2.23, Mpost = 8.60 ± 0.94; p < 0.01), and T2D (Mpre = 6.95 ± 1.57, Mpost = 8.25 ± 0.72; p < 0.01), and self-efficacy to deliver the program (Mpre = 7.93 ± 1.51, Mpost = 9.01 ± 1.00; p < 0.01) all significantly increased from pre- to post e-learning training. Participants reported positively on the user satisfaction and feedback questionnaire with a mean score of 4.58/5 (SD = 0.36). These findings suggest e-learning platforms are a promising mode to improve DPP coaches' knowledge, counseling skills, and to bolster confidence in program delivery with high levels of satisfaction. E-learning to train DPP coaches allows for effective and feasible expansion of DPP's, ultimately permitting more reach to adults living with prediabetes.

Human high-density lipoprotein microtranscriptome is unique and suggests an extended role in lipid metabolism

Aim: To comprehensively characterize the high-density lipoproteins (HDLs) microtranscriptome and to assess whether it is distinct from that of plasma and different between women and men. Methods: RNA was extracted from ultracentrifugation-purified HDLs and plasma from 17 healthy women and men couples, and libraries were sequenced on a HiSeq2500 platform. Results: On average, 310 ± 64 and 355 ± 31 miRNAs were detected (≥1 read per million) in HDLs and plasma, respectively. A total of 62 and 134 miRNAs were over-represented (e.g., miR-150-5p; fold change = 7.52; p_adj = 5.41 × 10^-111) and under-represented (e.g., miR-22-3p; fold change = -5.28; p_adj = 2.11 × 10^-154) in HDLs compared with plasma. These miRNAs were enriched in lipid metabolism and cellular processes-related pathways. Conclusion: HDLs exhibit a sex-independent miRNA profile distinct from that of plasma. These miRNAs may contribute to the HDLs' physiology.

A narrative systematic review of factors affecting diabetes prevention in primary care settings

BACKGROUND

Type 2 diabetes is impacting millions of people globally; however, many future cases can be prevented through lifestyle changes and interventions. Primary care is an important setting for diabetes prevention, for at-risk populations, because it is a patient's primary point of contact with the health care system and professionals can provide lifestyle counselling and support, as well as monitoring health outcomes. These are all essential elements for diabetes prevention for at-risk adults.

AIM

To understand the factors related to the delivery and uptake of type 2 diabetes prevention interventions within primary care in higher income countries.

METHODS

For this narrative systematic review, we combined qualitative and quantitative studies of diabetes prevention within a primary care setting for patients at-risk of developing the condition. We used an iterative approach for evidence collection, which included using several databases (MEDLINE, Embase, Pysch info, BNI, SSCI, CINAHL, ASSIA), where we combined diabetes terms with primary care terms. Narrative and thematic synthesis were utilised to identify the prominent themes emerging from the data.

RESULTS

A database of 6646 records was screened by the research team, and 18 papers were included. Three major themes were identified in this review. The first theme of context and setting of diabetes progression includes the risk and progression of diabetes, primary care as a setting, and where the responsibility for change is thought to lie. This review also found mixed views on the value of preventative services within primary care. The second theme focused on the various patient factors associated with diabetes prevention such as a patient's motivation to modify their current lifestyle, perceptions and knowledge (or lack thereof) of the impacts of diabetes, lack of follow-up in healthcare settings, and trust in healthcare professionals. The third theme was centred on professional factors impacting on diabetes prevention which included workload, time constraints, resources, self-efficacy and knowledge as well as professionals' perception of patient motivations towards change.

CONCLUSION

This review explored the factors influencing diabetes prevention in primary care, and identified the context of prevention, as well as patient and professional factors related to preventative services being offered in primary care. This systematic review complements previous reviews of real-world settings by exploring the significant factors in prevention, and the findings are relevant to academics, policymakers, patients and practitioners interested in understanding the factors associated with the delivery and uptake of diabetes prevention interventions.

The association of early life socioeconomic conditions with prediabetes and type 2 diabetes: results from the Maastricht study

Background

Using cross-sectional data from The Maastricht Study, we examined the association of socioeconomic conditions in early life with prediabetes and T2DM in adulthood. We also examined potential mediating pathways via both adulthood socioeconomic conditions and adult BMI and health behaviours.

Methods

Of the 3263 participants (aged 40–75 years), 493 had prediabetes and 906 were diagnosed with T2DM. By using logistic regression analyses, the associations and possible mediating pathways were examined.

Results

Participants with low early life socioeconomic conditions had a 1.56 times higher odds of prediabetes (95% confidence interval (CI) = 1.21-2.02) and a 1.61 times higher odds of T2DM (95% CI = 1.31-1.99). The relation between low early life socioeconomic conditions and prediabetes was independent of current socioeconomic conditions (OR = 1.38, 95% CI = 1.05-1.80), whereas the relation with T2DM was not independent of current socioeconomic conditions (OR = 1.10, 95% CI = 0.87-1.37). BMI party mediated the association between early life socioeconomic conditions and prediabetes.

Conclusions

Socioeconomic inequalities starting in early life were associated with diabetes-related outcomes in adulthood and suggest the usefulness of early life interventions aimed at tackling these inequalities.

Platelet-derived miR-103b as a novel biomarker for the early diagnosis of type 2 diabetes

AIMS

MicroRNA-103 (miR-103) plays a critical role in regulating glucose homeostasis in type 2 diabetes (DM2). Recent data suggest that secreted frizzled-related protein 4 (SFRP4) serves as a potential risk biomarker for prediabetic mellitus (pre-DM) and that platelets are enriched for miR-103. The objective of this study was to test the hypothesis that platelet-derived miR-103b (miR-103-as), which regulates SFRP4, might be a novel biomarker for the early diagnosis of DM2.

METHODS

We evaluated platelet miR-103b expression in healthy subjects (n = 46), pre-DM subjects (n = 48), non-complicated diabetic subjects (n = 43) and diabetes mellitus type 2-coronary heart disease subjects (n = 36), respectively, and analyzed the relationship of these levels with its target gene SFRP4.

RESULTS

In qRT-PCR assays, miR-103b were significantly down-regulated, and conversely, the expression of the SFRP4 gene was up-regulated in pooled leukocyte-depleted platelets and individual subjects with pre-DM. Additionally, patients who had undergone antiplatelet treatment were characterized by decreased gene expression of SFRP4 and increased levels of platelet-derived miR-103b. miR-103b modulated reporter gene expression through SFRP4 mRNA 3'-UTR seed sequence and negatively regulated its expression. Furthermore, SFRP4 mRNA and protein levels were down-regulated by a miR-103b mimic but were up-regulated by a miR-103b inhibitor.

CONCLUSIONS

The results suggest that platelet-derived miR-103b could negatively regulate the expression of SFRP4 mRNA/protein in pre-DM2, indicating that miR-103b could be a novel biomarker for the early diagnosis of DM2.
