Journal of Diabetes Investigation: Vol. 13, Issue 3 Review
In this issue of the Journal of Diabetes Investigation, clinical researchers explore several critical facets of diabetes management, complications, and early risk assessment. Key investigations focus on the metabolic impacts of clinical dropout, the synergistic dangers of combined vision and hearing impairments on cardiovascular outcomes, and nuanced screening metrics for prediabetes.
Key Takeaways for Patients and Families: Continuous clinical oversight remains the cornerstone of safe diabetes management. Gaps in care can trigger severe blood sugar spikes, particularly for patients prescribed insulin or sulfonylureas. Furthermore, sensory health assessments (vision and hearing) are shown to be essential indicators of overall cardiovascular risk, and early-stage screening tools like the Visceral Adiposity Index (VAI) or combined ankle-brachial index sweat tests are making preventative interventions more precise than ever.

Glycemic Deterioration After Dropping Out of Type 2 Diabetes Care
Research Objective: To identify factors associated with worsening blood sugar control (HbA1c) when patients with type 2 diabetes temporarily stop receiving clinical care.
Methods: A retrospective cohort study analyzed medical claims and health checkup data of 1,125 Japanese workers with type 2 diabetes who had paused their clinical care for at least 4 months after receiving continuous care for over 1.5 years.
Main Findings: Following an average dropout period of 9.3 months, the average HbA1c level rose from 6.8% to 7.6%. Patients who were taking insulin or sulfonylureas before their dropout experienced a severe increase in HbA1c of approximately 2% or more, even if their blood sugar had been well-controlled prior to the gap in treatment. Patients not on medication experienced far smaller increases (+0.5%).
Clinical Significance: A temporary halt in care poses a high risk for rapid metabolic deterioration, especially for those dependent on advanced glucose-lowering drugs.
What this means for you: Skipping your diabetes clinic appointments is dangerous, particularly if you are prescribed insulin or sulfonylureas. Even if your blood sugar feels controlled, stopping therapy without supervision can lead to rapid and severe health setbacks.
Impact of Vision and Hearing Impairments on Cardiovascular Health in Type 2 Diabetes
Research Objective: To examine how vision loss, hearing loss, or a combination of both relates to cardiovascular disease risk and overall mortality in individuals with type 2 diabetes.
Methods: A large nationwide cohort study evaluated 771,128 patients with type 2 diabetes in South Korea, comparing rates of myocardial infarction (MI), stroke, and mortality among those with and without sensory impairments.
Main Findings: Patients with sensory deficits exhibited elevated risk profiles. Those suffering from both vision and hearing impairments had the highest vulnerability, presenting an adjusted hazard ratio of 1.362 for MI and 1.591 for mortality. Vision loss alone was linked to a higher risk of adverse cardiovascular outcomes and mortality than hearing loss alone.
Clinical Significance: Vision and hearing impairments serve as potent independent and synergistic markers for severe cardiovascular events and overall mortality in diabetes patients.
What this means for you: Routine eye and ear examinations do more than protect your senses; they are vital windows into your heart and vascular system. If you notice deterioration in your sight or hearing, discuss cardiovascular screening with your doctor.
Fasting Plasma Glucose of 90–99 mg/dL and Type 2 Diabetes Risk
Research Objective: To clarify whether a fasting blood sugar level between 90 and 99 mg/dL—traditionally considered "normal"—increases the risk of developing type 2 diabetes.
Methods: This long-term retrospective cohort study tracked 37,148 Japanese individuals with normal baseline blood glucose over a 10-year period (2008 to 2018).
Main Findings: Within the 90–99 mg/dL range, the risk of developing type 2 diabetes rose by 9% for every 1 mg/dL increase. Compared to individuals with fasting glucose ≤89 mg/dL, those at 98–99 mg/dL had over a 3.4-fold higher risk of developing diabetes, with the hazard ratio remaining highly pronounced among individuals with obesity.
Clinical Significance: The risk of progressing to type 2 diabetes increases linearly and significantly even within what is widely considered a normal fasting blood sugar range.
What this means for you: Having a fasting blood sugar level in the high 90s is not entirely risk-free. It serves as an early warning, particularly if you are carrying extra weight, indicating that proactive lifestyle modifications could prevent diabetes.
LncRNA ATP2B1-AS1 Regulates Blood Vessel Leakage in Diabetic Retinopathy
Research Objective: To investigate how the long non-coding RNA (lncRNA) ATP2B1-AS1 influences biological abnormalities in retinal cells exposed to high sugar levels.
Methods: A laboratory-based molecular study evaluating human retinal endothelial cells (HRECs) under high-glucose conditions mimicking diabetes.
Main Findings: ATP2B1-AS1 was found to be downregulated in diabetic retinopathy. Artificially restoring (overexpressing) its levels significantly reduced cell growth, cellular migration, unwanted new blood vessel growth (angiogenesis), and vessel leakiness (permeability) induced by high glucose. This protective effect occurred because ATP2B1-AS1 acts as a "sponge" for miR-4729, which in turn regulates the IQGAP2 gene.
Clinical Significance: This study maps out a new genetic protective pathway in retinal cells, opening the door for future targeted genetic therapies to prevent vision loss.
What this means for you: Researchers are pinpointing the exact genetic mechanisms behind eye damage caused by diabetes. Discoveries like this help pave the way for highly targeted medications in the future to stop retinopathy before it damages sight.
Visceral Adiposity Index as an Indicator for Prediabetes Risk
Research Objective: To synthesize existing observational evidence to clarify whether the Visceral Adiposity Index (VAI)—a combined measure of fat distribution and lipid levels—is associated with prediabetes risk.
Methods: A systematic meta-analysis combining data from 10 observational studies involving a total of 112,603 participants.
Main Findings: Higher VAI scores were significantly associated with an elevated risk of prediabetes. The overall combined odds ratio of VAI for prediabetes was 1.68, although there was notable heterogeneity and publication bias across the studied pools.
Clinical Significance: VAI serves as a useful lipid-and-body-measurement index that clinicians can use to flag individuals who are highly likely to develop prediabetes.
What this means for you: Evaluating your risk for prediabetes involves more than just a scale. By looking at a combined picture of your body fat distribution and cholesterol panel, doctors can better understand your risk and help you take preventative action early.
Simplified Combination Therapy vs. Multiple Daily Injections in Japanese Type 2 Patients
Research Objective: To compare the clinical efficacy, safety, and blood sugar stability of a simplified once-daily combined injection (iGlarLixi + insulin glulisine) against a traditional intensive multiple daily injection (MDI) regimen.
Methods: A randomized trial involving 40 hospitalized Japanese type 2 diabetes patients, monitored with intermittent continuous glucose monitoring (iCGM) to adjust doses and track glucose metrics.
Main Findings: Both therapies offered comparable "time in range" (healthy blood sugar window). However, the combined iGlarLixi + glulisine therapy significantly reduced time spent in hypoglycemia (low blood sugar), required a shorter medication adjustment (titration) period, and simplified the overall treatment process.
Clinical Significance: Transitioning to a simplified combined therapy maintains strong blood sugar control while offering a safer profile with fewer daily injections and lower hypoglycemia risks.
What this means for you: Managing diabetes does not always have to mean taking numerous complex shots. Combined formulas can provide equivalent glycemic control with fewer needle sticks and a lower danger of sudden, scary low blood sugar events.
Effects of EPA on Selenoprotein P and Organ-Specific Insulin Sensitivity
Research Objective: To investigate if taking eicosapentaenoic acid (EPA)—a polyunsaturated fatty acid—reduces circulating levels of Selenoprotein P (SeP, a protein that induces insulin resistance) and improves organ-specific insulin response in humans.
Methods: 20 participants with dyslipidemia and type 2 diabetes were randomized to receive 900 mg of EPA twice daily or control for 12 weeks. Detailed insulin sensitivity tests (hyperinsulinemic-euglycemic clamp with stable isotope tracer) were conducted.
Main Findings: Overall circulating SeP levels did not decrease in either group. However, EPA treatment significantly improved insulin sensitivity in fat (adipose) tissue. In individual correlations, higher EPA levels were positively associated with improved hepatic (liver) insulin sensitivity, though surprisingly showing a negative association in skeletal muscle.
Clinical Significance: EPA's ability to bolster insulin response in the liver and fat tissues appears to work through complex, tissue-specific mechanisms independent of circulating SeP levels.
What this means for you: High-quality EPA (often derived from fish oil) can help improve how your body fat and liver respond to insulin. However, its metabolic actions are complex, so it should be used in coordination with your standard medical therapies.
Combining Ankle-Brachial Index and Foot Sweat Conductance for Early Leg Artery Disease
Research Objective: To evaluate the early diagnostic value of combining the ankle-brachial index (ABI) with feet electrochemical skin conductance (FESC, measuring sweat response) to detect peripheral artery disease (PAD) in Chinese type 2 diabetes patients.
Methods: Evaluated 183 type 2 diabetes patients who were classified into three groups: uncomplicated diabetes, patients with nerve damage (neuropathy), and patients with established PAD.
Main Findings: FESC (measured via a rapid Sudoscan test) was identified as an independent risk factor for developing PAD. Combining the standard ankle-brachial blood pressure index with FESC produced excellent diagnostic results, achieving an accuracy area under the curve (AUC) of 0.907, with 91.4% specificity and 75% sensitivity.
Clinical Significance: Combining vascular (ABI) and sweat gland nerve (FESC) screenings provides an accurate, non-invasive method for detecting diabetes-related leg artery blockages at a very early stage.
What this means for you: Simple, non-invasive skin tests on your feet combined with blood pressure checks on your limbs can detect early signs of poor circulation. Catching these problems early is the key to preventing serious diabetic foot ulcers.
