Effect of Hyperglycaemia and Moxifloxacin on QTc Interval in T2DM

Diabetes is a significant risk factor for sudden cardiac death, with the QTc interval on electrocardiograms (ECGs) often prolonged in diabetic patients due to factors such as hyperglycaemia and insulin resistance. Drugs like moxifloxacin can further exacerbate this effect, especially in those with diabetes. A previous trial on Type 1 diabetes suggested that hyperglycaemia and moxifloxacin have additive effects, prompting an investigation into whether similar effects occur in Type 2 diabetes (T2DM), particularly in individuals with high insulin resistance. This study aims to evaluate whether moxifloxacin-induced QT-prolongation is amplified by elevated blood glucose levels or insulin deficiency in T2DM patients, considering potential differences between sexes. Blood biomarkers will be analysed to understand the underlying molecular mechanisms. The trial will involve at least 24 male and female participants with insulin-resistant T2DM, aged 18 to 64 years, conducted at Richmond Pharmacology Ltd. Participants will receive treatments with glucose, moxifloxacin, and placebos while closely monitored for side effects during an inpatient stay, followed by outpatient appointments.

To Assess the Prevalence, Management Practices, and Clinical Outcomes Associated With Hyperglycemia Among Hospitalized Patients, With a Particular Focus on the Interplay Between Metabolic Biomarkers, Nutritional Status, and Body Composition

This was a prospective, observational cross-sectional study conducted at a tertiary care private hospital in India. The study was designed to comprehensively evaluate the prevalence, management strategies, and clinical outcomes of in-hospital hyperglycemia among adult inpatients. The study also explored the associations of metabolic biomarkers-fetuin-A and fibroblast growth factor-21 (FGF-21) as well as sarcopenic obesity and nutritional factors with clinical outcomes, including length of hospital stay (LOS), complications, and mortality. Institutional Ethics Committee approval was obtained prior to study initiation, and written informed consent was secured from all participants

Perioperative Evaluation of Glucose Profile Using Continuous Glucose Monitoring System in Glucose Intolerant Patients

The recent use of a pre-operative carbohydrate loading compared to fasting has been shown to improve the early recovery after surgical procedures by reducing the profound stress response following surgery and allowing a better postoperative blood glucose regulation by lowering insulin resistance. The responsible mechanisms of T2D remission after bariatric surgery are not completely understood and guidelines for the early management of T2D and GI following bariatric surgery are lacking, resulting in highly variable postoperative glucose control. No other study has yet investigated the effect of preoperative carbohydrate loading on glucose control the first days after the bariatric surgery in patients who have poor glycemic control

New Taipei City 888 Digital Medical AI Platform for Prevention and Care of the Three Highs and Cardio-Renal-Vascular Diseases

Non-communicable diseases (NCDs), or chronic diseases, are a major public health burden globally and in Taiwan, and control of the "three highs" (hypertension, dyslipidemia, and hyperglycemia) is a national priority. Nearly half of the 10 leading causes of death in Taiwan are directly or indirectly related to atherosclerotic cardiovascular disease (ASCVD), for which hypertension, dyslipidemia, and abnormal blood glucose are the major risk factors. National health insurance data indicate that over 70% of middle-aged and older adults have at least one of these chronic conditions. Early stages are often asymptomatic, and inadequate control may lead to complications of cardiovascular disease, stroke, renal vascular disease, and retinopathy, causing irreversible organ damage and death. For blood pressure, large clinical trials such as SPRINT and STEP have shown that targeting systolic blood pressure below 130 mmHg significantly reduces ASCVD events. For LDL cholesterol, "the lower, the better" applies, with guideline-recommended LDL-C targets determined by baseline ASCVD risk, with levels below 55 mg/dL for very high-risk patients. For diabetes, treatment goals generally include fasting plasma glucose below 130 mg/dL and glycated hemoglobin (HbA1c) below 7%. Although antihypertensive therapy has been proven effective in preventing cardiovascular disease and chronic kidney disease attributable to hypertension, fewer than one-third of patients receiving antihypertensive medications achieve current guideline-recommended blood pressure targets. No randomized clinical trial to date has used home blood pressure as the primary therapeutic reference. Moreover, long-term evidence is lacking regarding the organ-protective effects of strategies targeting morning hypertension and of bedtime dosing regimens. Although the TIME study is currently the largest and longest-followed trial addressing dosing time, its bedtime-dosing arm was not specifically targeted to patients with morning hypertension. Therefore, we propose a clinical trial to investigate management strategies for morning hypertension. Aligned with the 2022 Taiwan Hypertension Guidelines, we will employ the "722 protocol" for home blood pressure monitoring and enroll patients with morning home blood pressure ≥130/80 mmHg to compare selective nocturnal administration of antihypertensive agents versus exclusive morning dosing, assessing differences in morning home blood pressure control rates, end-organ damage, and atherosclerotic cardiovascular disease (ASCVD) events. This project will implement two large-scale cluster-randomized clinical trials within the New Taipei City healthcare network. The first trial (T-888-DIGICARE) will evaluate whether a mobile digital health platform augmented with interactive digital modules can more effectively achieve the "888" targets for prevention and treatment of the Three Highs (Hypertension, Hyperglycemia, Hyperlipidemia). The second trial (DREAM-G) will use the same mobile health delivery model to investigate whether the timing of antihypertensive medication administration (nocturnal versus morning dosing) differentially affects patients with poor morning home blood pressure control. Beyond generating rigorous evidence through a novel clinical approach, this program is expected to have substantial global clinical impact and to showcase Taiwan's healthcare capabilities internationally. Operational challenges encountered and solutions developed during the trials will also provide critical feasibility data for the concurrent real-world implementation registry (T-888-DIGICARE-Registry). The registry will run in parallel with the cluster trials and will enroll individuals who decline trial participation at baseline as well as participants after trial completion, thereby serving as a continuity and real-world evidence platform.

Validation of Remote Photoplethysmography for Non-Invasive Estimation of Blood Glucose and HbA1c

The goal of this observational study is to evaluate whether a non-invasive facial scan technology using remote photoplethysmography (rPPG) can accurately estimate blood glucose and HbA1c levels in adults living in the community in Jakarta. The study focuses on adults aged 18 years and older, including individuals with or without diabetes. The main questions it aims to answer are: 1. Can rPPG-based facial scan estimates of blood glucose and HbA1c match results from standard laboratory blood tests? 2. How well can rPPG identify individuals with high blood sugar or diabetes risk based on established clinical cut-off values? Researchers will compare results from the rPPG facial scan with standard laboratory measurements of fasting blood glucose and HbA1c to determine how accurate and reliable the technology is for screening purposes. Participants will: 1. Provide basic information such as age, sex, and medical history 2. Undergo a non-invasive facial scan using a smartphone-based system 3. Have a blood sample taken to measure fasting blood glucose and HbA1c 4. Complete all assessments during a single study visit This study aims to determine whether rPPG can serve as a simple, non-invasive, and accessible tool for early detection and monitoring of diabetes in community settings.

Phase 1 Trial of Arginine Hydrochloride for the Management of Diabetic Ketoacidosis in Type 2 Diabetes

Diabetic ketoacidosis (DKA) is increasingly recognized in adults with "ketone-prone" type 2 diabetes. In many of these patients, the pancreas can still make insulin but becomes temporarily "stunned" during severe, prolonged high blood sugar. Arginine is a naturally occurring amino acid that can trigger the pancreas to release its own insulin when glucose is high. It is FDA-approved for other uses and has been given intravenously for decades with a strong safety record. Whether a single arginine infusion given early during DKA can safely boost the body's insulin and speed recovery has not been tested. This randomized, double-blind, placebo-controlled, phase 1/2 trial will enroll 60 adults who present to one of four Detroit-area emergency departments with DKA consistent with ketone-prone type 2 diabetes (high glucose and significant ketones). Participants will receive standard DKA care ordered by their clinicians. In addition, under blinded conditions they will receive either arginine hydrochloride 30 grams (in 300 mL) or placebo (normal saline), infused intravenously over 30 minutes as early as feasible after DKA is recognized. The main question is whether arginine increases endogenous (self-made) insulin soon after infusion. We will measure C-peptide (a marker released in equal amounts with insulin) and glucose at 10, 30, and 90 minutes after the start of the infusion and calculate the C-peptide/glucose ratio. Secondary measures include the rate of ketone (β-hydroxybutyrate) clearance and the total insulin dose required in the first 24 hours. Additional blood tests will examine arginine and related amino acids, and a small sample of platelets will be used to explore mitochondrial function. Safety will be closely monitored during and after the infusion, and participants will be contacted at 90 days to assess for any delayed problems. Potential risks include temporary flushing, nausea, or headache; the infusion can be stopped at any time if needed. Potential benefits include faster resolution of ketosis and reduced insulin needs, but benefits cannot be guaranteed for individual participants.

Liraglutide-bolus vs Glargine-bolus Therapy in Overweight/Obese Type 2 Diabetes Patients (LiraGooD)

The present 24-week, prospective, open-label, randomized, multicenter, parallel group trial is carried to investigate and evaluate the efficacy and safety of Liraglutide in combination with prandial insulin therapy vs insulin glargine in combination with prandial insulin therapy in overweight / obese patients with uncontrolled type 2 diabetes.

Insulin Therapy for Postreperfusion Hyperglycemia

Glycemic control during liver transplantation is challenging especially after reperfusion of the liver graft. Insulin dose to treat postreperfusion hyperglycemia is retrospectively analyzed using historical data. The proposed dose then is prospectively applied to the patients to assess the adequacy of the insulin dose.
