Background: We analyzed variables reported during routine clinical practice using a registrational database to estimate risk factors for depression in people with type 2 diabetes mellitus.

Methods: A Patient Health Questionnaire (PHQ-9) score of 15 was selected as the cut-off for clinically meaningful depression. Missing data was either filled in with a median value, the k -nearest neighbors' method, or the entire variable was removed.

We present an in-depth analysis of dyslipidemia management strategies for patients with diabetes mellitus in Taiwan. It critically examines the disparity between established guideline recommendations and actual clinical practices, particularly in the context of evolving policies affecting statin prescriptions. The focus is on synthesizing the most recent findings concerning lipid management in patients with diabetes mellitus, with a special emphasis on establishing consensus regarding low-density lipoprotein cholesterol treatment targets.

Introduction: Health2Sync (H2S) is a digital health technology platform that provides coaching and titration support to patients with diabetes. The Mallya cap converts a conventional insulin pen into a smart connected device that can automatically synchronize dose values and associated timestamps (upon injection) to the H2S platform. This single-arm real-world study evaluated the effectiveness of insulin glargine 300 U/mL (Gla-300) combined with H2S and Mallya cap (Gla-300 + Cap + App program) on clinical outcomes among users with type 2 diabetes (T2D) in Taiwan.

Postmenopausal women are at significant risk for osteoporotic fractures due to their rapid bone loss. Half of all postmenopausal women will get an osteoporosis-related fracture over their lifetime, with 25% developing a spine deformity and 15% developing a hip fracture. By 2050, more than half of all osteoporotic fractures will occur in Asia, with postmenopausal women being the most susceptible.

Background: Assessment of renal size is clinically significant for the screening, diagnosis, and follow-up of renal diseases as the basis of clinical decisions. However, the relationship of renal dimension with age, body indices, and the estimated glomerular filtration rate (eGFR) has rarely been reported in the Chinese type 1 diabetes mellitus (T1DM) population.

Methods: A total of 220 T1DM patients were retrospectively analyzed from the Chang Gung Research Database in Taiwan.

Diabetes mellitus (DM) and hepatitis C virus (HCV) infection are prevalent diseases globally and emerging evidence demonstrates the bidirectional association between the two diseases. Direct-acting antivirals (DAAs) for HCV have a high treatment success rate and can significantly reduce the risks of short and long-term complications of HCV infection. However, despite the evidence of the association between diabetes and HCV and the benefits of anti-HCV treatment, previously published guidelines did not focus on the universal HCV screening for patients with diabetes and their subsequent management once confirmed as having HCV viremia.

Article Synopsis
  • * The research analyzed data from over 1.8 million childbirths and found that women with hyperglycemia experienced higher hospitalization rates and longer stays compared to those without diabetes.
  • * Women with gestational diabetes (GDM) showed a slight improvement in 30-day readmission rates, but overall differences in emergency department visits and outcomes remained modest compared to those without diabetes or GDM.

  • Osteoporosis is a significant issue for patients with Cushing’s syndrome (CS), yet limited research exists on its risk factors, particularly in Taiwan.
  • The study analyzed data from 356 patients with CS, revealing that 58.1% had osteoporosis, with lower serum calcium levels linked to a higher risk of developing it.
  • Additionally, hypocalcemia was found to be associated with increased risks of heart failure and stroke, highlighting the importance of calcium supplementation and appropriate treatment for these patients to prevent fractures and disablement.

Context: There is a medical need for effective insulin-independent antidiabetic drugs that can promote pancreatic β-cell function and have a low risk of hypoglycemia in type 2 diabetes mellitus (T2DM) patients. R-form verapamil (R-Vera), which is able to enhance the survival of β-cells and has higher cardiovascular safety margin compared with racemic verapamil, was developed as a novel approach for T2DM treatment.

Objective: This randomized, double-blind, placebo-controlled clinical trial was designed to evaluate the efficacy and safety of 3 dosages of R-Vera added to ongoing metformin therapy in T2DM patients who had inadequate glycemic control on metformin alone.

Background: Growth differentiation factor (GDF15) is a superfamily of transforming growth factor-beta which has been suggested to be correlated with various pathological conditions. The current study aimed to investigate the predicted role of circulating GDF15 in diabetic metabolism characteristics and diabetic neuropathy. Methods: 241 diabetic patients and 42 non-diabetic subjects were included to participate in the study.

Past studies have confirmed that glucagon-like peptide 1 (GLP-1) receptor agonists can improve renal outcomes in patients with type 2 diabetes mellitus (DM). This study aimed to evaluate whether dipeptidyl peptidase 4 (DPP-4) inhibitors, which elevate GLP-1 levels, also have similar effects on renal function. In this retrospective study, diabetic patients treated with anti-hyperglycemic agents between 2008 and 2011 were selected.

Background: To determine a reliable method to predict prevalent vertebral fractures (VF) by assessing the association between dysmobility syndrome (DS) and VF in a community-dwelling population.

Methods: This cross-sectional study enrolled 518 participants from fracture-prevention educational activities held in multiple communities in Taiwan. Assessments included questionnaires, fracture risk assessment tool (FRAX), bone mineral density (BMD) and body composition using dual-energy x-ray absorptiometry (DXA), lateral thoracolumbar spine x-rays (specifically T8-S1), grip strength (GS), walking speed, and fall history.

Article Synopsis
  • Identifying genetic variants linked to diabetes can help tailor treatments for type 2 diabetes patients, with a focus on both nuclear and mitochondrial DNA.
  • A study involving 604 Taiwanese subjects explored how mitochondrial haplogroups and nuclear DNA risk alleles relate to clinical characteristics and the need for insulin treatment.
  • Findings suggest that mitochondrial haplogroup D4 is associated with a lower likelihood of requiring insulin, unlike certain nuclear genetic variants, indicating the significance of mitochondrial influences in diabetes management.

Aims/introduction: Clinical studies show that either heart rate variability (HRV) or electrochemical skin conductance (ESC) alone can serve as a simple and objective method for screening cardiovascular autonomic neuropathy (CAN). We tested the hypothesis that combining these two quantitative approaches can not only reinforce accuracy in CAN screening but also provide a better estimate of CAN severity in patients with type 2 diabetes (T2DM) who had already had CAN in outpatient clinics.

Materials And Methods: Each patient received a complete battery of cardiovascular autonomic reflex tests (CARTs), with ESC measured by SUDOSCAN, time domain of HRV measured by standard deviation of all normal RR intervals (SDNN) and frequency domain of HRV (low frequency [LF], high frequency [HF], and LF/HF ratio), and peripheral blood studies for vascular risk factors.

  • Bisphosphonates (BPs) were found to lower the risk of all-cause mortality in osteoporosis patients with a history of acute coronary syndrome (ACS) or acute ischemic stroke (AIS) over an 8-year period.
  • The study compared outcomes between osteoporosis patients using BPs and those not using them, revealing that risks for major cardiovascular events were generally similar across both groups.
  • Despite the benefits in mortality, BP users showed a higher likelihood of hospitalization for atrial fibrillation, indicating the need for caution among patients with prior cardiovascular issues.
