Journal of Diabetes Investigation: Vol. 14, Issue 10 Summary
This issue of the Journal of Diabetes Investigation highlights crucial clinical and basic science research aimed at improving safety, understanding broader health risks, and uncovering the biological mechanisms of diabetes-related complications.
Key research themes explored in this issue include:
- Medication Safety (Polypharmacy): Exploring how structured, multidisciplinary team interventions can safely reduce the burden of taking multiple medications (polypharmacy) in hospitalized diabetes patients.
- Systemic Risks of Prediabetes: Evaluating the potential link between prediabetes and increased risk of lung cancer incidence and mortality.
- Organ Crosstalk in Diabetes: Investigating how fat cells communicate with liver cells under high glucose conditions, accelerating fatty liver disease.
For patients and families, these findings underscore the clinical importance of comprehensive care—ranging from careful medication reviews to early lifestyle changes that address metabolic health before full-blown diabetes develops.

Effectiveness of countermeasure for polypharmacy by multidisciplinary team review in patients with diabetes mellitus
Authors: Shohei Nishida, Takehiro Kato, Yuichi Hayashi, Shoya Yamada, Hironori Fujii, Michi Yamada, Nao Asai, Shinya Shimizu, Takashi Niwa, Hirotoshi Iihara, Sodai Kubota, Mayu Sakai, Yoshihiro Takahashi, Ken Takao, Masami Mizuno, Takuo Hirota, Ryo Kobayashi, Yukio Horikawa, Daisuke Yabe, Akio Suzuki
Research Objective:
To evaluate whether a structured program combining pharmacist checks with a multidisciplinary clinical team review can safely reduce the number of inappropriate medications (polypharmacy) in patients hospitalized for diabetes.
Methods:
This single-center, retrospective study included 102 patients with diabetes who were taking six or more medications upon admission to the Gifu University Hospital diabetes ward between July 2021 and June 2022. Pharmacists used a dedicated checklist to spot potentially inappropriate medications, which were then reviewed by a multidisciplinary clinical team for potential discontinuation. Medication numbers were compared between admission and discharge, and patients were monitored for any decline in health.
Main Findings:
Out of 308 admitted patients, 102 met the criteria for polypharmacy (taking 6+ drugs). Following the team's review, 84 inappropriate or potentially inappropriate medications were discontinued. The average number of medications per patient decreased significantly from 9.26 on admission to 8.42 at discharge. Follow-up monitoring confirmed that the reduction in medications did not cause any deterioration in the patients' health conditions.
Clinical Significance:
Polypharmacy increases the risk of side effects and drug interactions. This study shows that a collaborative review process involving pharmacists and doctors can safely and effectively trim down unnecessary drug prescriptions in diabetes patients.
Key Points for Patients:
If you are taking many different medications, it can sometimes lead to unnecessary side effects or confusion. A regular review of your medications by a clinical team can help safely reduce your pill burden without harming your health. Always consult your doctor before stopping any prescribed medication.
Prediabetes and the risk of lung cancer incidence and mortality: A meta‐analysis
Authors: Enjian Shen, Xi Chen
Research Objective:
To investigate whether prediabetes (elevated blood sugar levels that are not yet high enough to be classified as type 2 diabetes) is associated with an increased risk of developing or dying from lung cancer.
Methods:
The researchers conducted a systematic review and meta-analysis of 10 observational cohort studies retrieved from major medical databases (including Medline, Embase, Cochrane Library, and Web of Science) to examine the relationship between prediabetes and lung cancer outcomes in adult populations.
Main Findings:
Individuals with prediabetes had a mildly increased risk of developing lung cancer compared to individuals with normal blood sugar levels (normoglycemia) (Risk Ratio: 1.09). This increased risk was notable in men, but not statistically significant in women. Additionally, the analysis suggested that prediabetes might be associated with a higher risk of lung cancer-related mortality.
Clinical Significance:
These findings highlight that metabolic impairment, even at the prediabetic stage, could have wider health implications beyond cardiovascular and metabolic risks, potentially influencing cancer risk and outcomes.
Key Points for Patients:
Prediabetes is a warning sign that blood sugar is higher than normal. Managing prediabetes through healthy lifestyle changes, such as balanced nutrition and regular physical activity, is vital not only to prevent type 2 diabetes but also to help lower the risk of other serious health issues, including certain types of cancer.
LINC01705 derived from adipocyte exosomes regulates hepatocyte lipid accumulation via an miR‐552‐3p/LXR axis
Authors: Anhua Lin, Wenjing He
Research Objective:
To explore how high blood sugar levels prompt fat cells (adipocytes) to communicate with liver cells (hepatocytes), leading to fat buildup in the liver (fatty liver disease) in diabetic patients.
Methods:
Researchers isolated microscopic packages called "exosomes" released by human fat cells cultured under normal and high glucose conditions, as well as from patients with diabetes and those with diabetes complicated by fatty liver disease. They introduced these exosomes to laboratory-grown liver cells (HepG2) and measured fat accumulation and genetic activity within the liver cells.
Main Findings:
High glucose levels caused fat cells to release exosomes rich in a specific genetic molecule called LINC01705. Exosomes from patients with both diabetes and fatty liver disease showed the highest levels of LINC01705. When liver cells absorbed these exosomes, LINC01705 suppressed a protective molecule (miR-552-3p), triggering liver fat accumulation via the LXR pathway.
Clinical Significance:
This study reveals a new pathway of "cellular communication" between fat tissue and the liver under high glucose conditions, showing how poorly controlled blood sugar can directly promote fatty liver disease.
Key Points for Patients:
This basic scientific study helps us understand why having high blood sugar makes you more likely to develop a fatty liver. It shows that fat cells in the body can send chemical packages that cause liver cells to store unnecessary fat, emphasizing the importance of keeping blood sugar levels under control to protect your liver health.
