Abstract
AIM To evaluate the effect of age and disease duration on the efficacy and safety of iGlarLixi versus insulin glargine 100 units/ml (iGlar) or lixisenatide (Lixi) alone in Asian people with type 2 diabetes (T2D) uncontrolled on oral antidiabetic drugs (LixiLan-O-AP) or basal insulin ± oral antidiabetic drugs (LixiLan-L-CN). MATERIALS AND METHODS In this post hoc analysis, the glycated haemoglobin (HbA1c) changes were assessed from baseline to week 24 (LixiLan-O-AP) or 30 (LixiLan-L-CN) in subgroups defined by baseline age (<65, ≥65 years) and duration of T2D. The proportion who achieved the composite of HbA1c <7% (<53.0 mmol/mol) without weight gain and without symptomatic hypoglycaemia (plasma glucose ≤3.9 mmol/L) and the incidences of hypoglycaemia and gastrointestinal disorders were also analysed. RESULTS HbA1c reductions were consistently greater with iGlarLixi versus iGlar or Lixi across all subgroups, including participants aged ≥65 years and those with T2D for ≥15 or ≥20 years. Greater proportions of participants achieved HbA1c <7% (<53.0 mmol/mol) without weight gain or hypoglycaemia with iGlarLixi versus iGlar or Lixi, regardless of age or T2D duration. Hypoglycaemia incidence was similar with iGlarLixi versus iGlar across most subgroups; the incidence of gastrointestinal disorders was lower with iGlarLixi versus Lixi in all subgroups. CONCLUSIONS iGlarLixi showed consistent efficacy and safety across all age and disease duration subgroups in Asian people with uncontrolled T2D, including older individuals and those with longstanding disease.

Abstract
The pathogenesis of diabetes is accompanied by increased levels of inflammatory factors, also known as "metabolic inflammation", which runs through the whole process of the occurrence and development of the disease. Mitochondria, as the key site of glucose and lipid metabolism, is often accompanied by mitochondrial function damage in type 2 diabetes mellitus (T2DM). Damaged mitochondria release pro-inflammatory factors through damage-related molecular patterns that activate inflammation pathways and reactions to oxidative stress, further aggravate metabolic disorders, and form a vicious circle. Currently, the pathogenesis of diabetes is still unclear, and clinical treatment focuses primarily on symptomatic intervention of the internal environment of disorders of glucose and lipid metabolism with limited clinical efficacy. The proinflammatory effect of mitochondrial damage-associated molecular pattern (mtDAMP) in T2DM provides a new research direction for exploring the pathogenesis and intervention targets of T2DM. Therefore, this review covers the most recent findings on the molecular mechanism and related signalling cascades of inflammation caused by mtDAMP in T2DM and discusses its pathogenic role of it in the pathological process of T2DM to search potential intervention targets.

Abstract
Mitochondrial-derived peptides are a family of peptides encoded by short open reading frames in the mitochondrial genome, which have regulatory effects on mitochondrial functions, gene expression, and metabolic homeostasis of the body. As a new member of the mitochondrial-derived peptide family, mitochondrial open reading frame of the 12S rRNA-c (MOTS-c) is regarding a peptide hormone that could reduce insulin resistance, prevent obesity, improve muscle function, promote bone metabolism, enhance immune regulation, and postpone aging. MOTS-c plays these physiological functions mainly through activating the AICAR-AMPK signaling pathways by disrupting the folate-methionine cycle in cells. Recent studies have shown that the above hormonal effect can be achieved through MOTS-c regulating the expression of genes such as GLUT4, STAT3, and IL-10. However, there is a lack of articles summarizing the genes and pathways involved in the physiological activity of MOTS-c. This article aims to summarize and interpret the interesting and updated findings of MOTS-c-associated genes and pathways involved in pathological metabolic processes. Finally, it is expected to develop novel diagnostic markers and treatment approaches with MOTS-c to prevent and treat metabolic disorders in the future.

Abstract
INTRODUCTION Pivotal trials documented glycemic benefits of fixed-ratio combination of insulin glargine 100 U/mL and lixisenatide (iGlarLixi), with no weight gain and low hypoglycemia risk in type 2 diabetes (T2D). This study aimed at assessing effectiveness and patterns of use of iGlarLixi in a real-world setting. METHODS This was a retrospective, multicenter, study, based on electronic medical records. All patients initiating iGlarLixi from May 2018 to July 2020 were considered. RESULTS Overall, 25 centers provided data on 675 patients initiating iGlarLixi with the following characteristics: age 66.4 ± 10.1 years, 54.2% men, T2D duration 15.5 ± 11.5 years, HbA1c 8.6 ± 1.4%, body mass index (BMI) 30.8 ± 5.3 kg/m2, 45.1% already treated with basal insulin, and 21.9% with basal bolus (± oral hypoglycemic agents). Metformin and sodium-glucose cotransporter-2 inhibitors were used in 76.0% and 0.9% of patients, respectively. Combinations of iGlarLixi with other glucose-lowering drugs such as sulfonylureas or short-acting insulin were found in 32.4% of patients. Effectiveness of iGlarLixi (N = 184) showed that HbA1c declined by 0.77% [95% confidence interval (CI) -1.00, -0.54] after 6 months. In combination with metformin and/or SGLT-2i (N = 117), HbA1c declined by -0.92% (95% CI -1.22, -0.62) and weight significantly decreased by 1.21 kg. iGlarLixi dose was suboptimally titrated. Safety data (N = 171) showed incidence rates of blood glucose ≤ 70 and < 54 mg/mL of 0.26 and 0.05 events per person-month during 6 months, respectively, with a risk reduction of about 75% with respect the 6 months before iGlarLixi initiation. No severe hypoglycemia was reported. CONCLUSION In adults with T2D, effectiveness and safety of iGlarLixi were documented in a real-world setting; appropriateness of use and adequate titration should be urgently improved so that clinical practice outcomes become more comparable to clinical trials results. Further real-world studies on the effect of iGlarLixi therapy are warranted.

Abstract
INTRODUCTION Combining basal insulin (BI) with glucagon-like peptide-1 receptor agonist (GLP-1RA) is recognized as a relevant option to optimize glucose control in type 2 diabetes (T2D). The EASY real-world study aimed to evaluate the modalities of initiation and the effectiveness of the insulin Degludec plus Liraglutide (IDegLira) fixed-ratio combination in the French health care system. METHODS A retrospective analysis included all patients with T2D and prior injectable therapy (GLP1-RA and/or insulin) who started treatment with IDegLira from September 2016 to December 2017 in 11 French diabetes centers. Baseline characteristics, reasons for IDegLira initiation, and modes of implementation were collected from the medical records. Changes in HbA1c and body weight were determined in patients with available follow-up data (nearest 6-month visit). RESULTS IDegLira was initiated in 629 patients previously treated with GLP-1RA alone (11.6%), insulin alone (31.5% including 16.5% with BI and 14.9% with multiple daily injections [MDI]) or a free combination of GLP-1RA and insulin (56.9% including 44.8% with BI and 12.1% with MDI), associated or not with oral agents. IDegLira starting dose (mean of 29 ± 11 dose steps) most often exceeded the recommended dose, and was significantly correlated with prior BI but not GLP-1RA dosage. At initiation, mean age, body mass index (BMI) and HbA1c were 60.1 ± 10.2 years, 33.4 ± 6.2 kg/m2 and 8.8 ± 1.7%, respectively. In 461 patients with available follow-up (median 178 days), HbA1c decreased in all subgroups submitted to treatment intensification (- 1.7 ± 1.8% [p < 0.0001], - 1.2 ± 1.8% [p < 0.001] and - 0.8 ± 1.8% [p = 0.0026] in patients with prior GLP-1RA, BI or MDI therapy, respectively) but also in those switching from BI and GLP-1RA free combination (- 0.2 ± 0.9%, p = 0.0419). Significant body weight gain occurred in patients previously treated with GLP-1RA alone (+ 1.5 ± 5.8 kg, p = 0.0572) or combined to BI (+ 1.0 ± 3.1 kg, p < 0.0001) while those on BI (- 1.4 ± 4.6 kg, p = 0.0139) or MDI (- 1.4 ± 5.0 kg, p = 0.0484) experienced weight loss. CONCLUSIONS While providing new information on the use of IDegLira in the French healthcare system, these data confirm the effectiveness of this fixed-ratio combination in the management of T2D.

Abstract
Morbidity and mortality from diabetes mellitus and associated illnesses is a major problem across the globe. Anti-diabetic medicines must be improved despite existing breakthroughs in treatment approaches. Diabetes has been linked to mitochondrial dysfunction. As a result, particular mitochondrial diabetes kinds like MIDD (maternally inherited diabetes & deafness) and DAD (diabetic autonomic dysfunction) have been identified and studied (diabetes and Deafness). Some mutations as in mitochondrial DNA (mtDNA), that encodes for a significant portion of mitochondrial proteins as well as mitochondrial tRNA essential for mitochondrial protein biosynthesis, are responsible for hereditary mitochondrial diseases. Tissue-specificity and heteroplasmy have a role in the harmful phenotype of mtDNA mutations, making it difficult to generalise findings from one study to another. There are a huge increase in the number for mtDNA mutations related with human illnesses that have been identified using current sequencing technologies. In this study, we make a list on mtDNA mutations linked with diseases and diabetic illnesses and explore the methods by which they contribute to the pathology's emergence.

Abstract
OBJECTIVE Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have significantly improved clinical effects on glycemic control. However, real-world data concerning the difference in gastrointestinal adverse events (AEs) among different GLP-1 RAs are still lacking. Our study aimed to characterize and compare gastrointestinal AEs among different marketed GLP-1 RAs (exenatide, liraglutide, dulaglutide, lixisenatide, and semaglutide) based on real-world data. METHODS Disproportionality analysis was used to evaluate the association between GLP-1 RAs and gastrointestinal adverse events. Data were extracted from the US FDA Adverse Event Reporting System (FAERS) database between January 2018 and September 2022. Clinical characteristics, the time-to-onset, and the severe proportion of GLP-1 RAs-associated gastrointestinal AEs were further analyzed. RESULTS A total of 21,281 reports of gastrointestinal toxicity were analyzed out of 81,752 adverse event reports, and the median age of the included patients was 62 (interquartile range [IQR] 54-70) years old. Overall GLP-1 RAs were associated with increased risk of gastrointestinal system disorders (ROR, 1.46; 95% CI, 1.44-1.49), which were further attributed to liraglutide (ROR, 2.39; 95% CI, 2.28-2.51), dulaglutide (ROR, 1.39; 95% CI, 1.36-1.42), and semaglutide (ROR, 3.00; 95% CI, 2.89-3.11). Adverse events uncovered in the labels included gastroesophageal reflux disease, gastritis, bezoar, breath odor, intra-abdominal hematoma, etc. Furthermore, it was observed that semaglutide had the greatest risk of nausea (ROR, 7.41; 95% CI, 7.10-7.74), diarrhea (ROR, 3.55; 95% CI, 3.35-3.77), vomiting (ROR, 6.67; 95% CI, 6.32-7.05), and constipation (ROR, 6.17; 95% CI, 5.72-6.66); liraglutide had the greatest risk of abdominal pain upper (ROR, 4.63; 95% CI, 4.12-5.21) and pancreatitis (ROR, 32.67; 95% CI, 29.44-36.25). Most gastrointestinal AEs tended to occur within one month. Liraglutide had the highest severe rate of gastrointestinal AEs (23.31%), while dulaglutide had the lowest, with a severe rate of 12.29%. CONCLUSION GLP-1 RA were significantly associated with gastrointestinal AEs, and the association was further attributed to liraglutide, dulaglutide, and semaglutide. In addition, semaglutide had the greatest risk of nausea, diarrhea, vomiting, constipation, and pancreatitis, while liraglutide had the greatest risk of upper abdominal pain. Our study provided valuable evidence for selecting appropriate GLP-1 RAs to avoid the occurrence of GLP-1 RA-induced gastrointestinal AEs.

Abstract
Despite novel therapeutic options, many people with type 2 diabetes (T2D) do not achieve their HbA1c targets. Given the progressive nature of T2D, many individuals not controlled with oral therapy will require advancement to injectable therapy using either a glucagon-like peptide-1 receptor agonist (GLP-1 RA), recently recommended as a first option, or traditionally a basal insulin. However, premix insulins remain frequently used, either as initial injectable therapy or as intensification from basal insulin. Premix insulin injections can potentially provide significant glycaemic improvements to basal insulin but at the expense of increased hypoglycaemia and weight gain and the need for multiple daily doses, which may affect treatment adherence. Real-world evidence suggests that glycaemic control often remains suboptimal with premix insulins. Fixed-ratio combinations (FRCs) of basal insulin and GLP-1 RAs provide a novel alternative to premix insulin for therapy intensification. While no direct comparisons between premix insulins and FRCs are available, results from meta-analyses suggest that FRCs may offer better HbA1c reductions, a lower risk of hypoglycaemia and less weight gain compared with premix insulin in a simplified treatment regimen. A head-to-head trial of T2D treatment intensification with premix insulin and a FRC of basal insulin plus a GLP-1 RA is currently in progress, which should help to clarify the outcomes for each treatment option. This review discusses the unmet needs of people with T2D treated with premix insulin and provides evidence supporting FRCs of basal insulin and GLP-1 RAs as an alternative treatment option.

Abstract
Diabetes mellitus and related disorders significantly contribute to morbidity and mortality worldwide. Despite the advances in the current therapeutic methods, further development of anti-diabetic therapies is necessary. Mitochondrial dysfunction is known to be implicated in diabetes development. Moreover, specific types of mitochondrial diabetes have been discovered, such as MIDD (maternally inherited diabetes and deafness) and DAD (diabetes and Deafness). Hereditary mitochondrial disorders are caused by certain mutations in the mitochondrial DNA (mtDNA), which encodes for a substantial part of mitochondrial proteins and mitochondrial tRNA necessary for mitochondrial protein synthesis. Study of mtDNA mutations is challenging because the pathogenic phenotype associated with such mutations depends on the level of its heteroplasmy (proportion of mtDNA copies carrying the mutation) and can be tissue-specific. Nevertheless, modern sequencing methods have allowed describing and characterizing a number of mtDNA mutations associated with human disorders, and the list is constantly growing. In this review, we provide a list of mtDNA mutations associated with diabetes and related disorders and discuss the mechanisms of their involvement in the pathology development.

Abstract
AIM In people with type 2 diabetes (T2D) requiring intensification beyond glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and oral antihyperglycaemic drugs (OADs), switching to iGlarLixi was shown to be efficacious and well-tolerated in the LixiLan-G trial. This exploratory analysis of LixiLan-G assessed the efficacy and safety of switching to iGlarLixi versus continuing GLP-1 RA therapy, stratified by screening HbA1c level (≥7.0 to ≤7.5 %; >7.5 to ≤8.0 %; >8.0 to ≤9.0 % [≥53 to ≤58 mmol/mol; >58 to ≤64 mmol/mol; >64 to ≤75 mmol/mol]) and previous GLP-1 RA regimen at screening (once/twice daily or once weekly). MATERIALS AND METHODS Endpoints for all subgroups included: change in HbA1c, achievement of HbA1c <7 % and hypoglycaemia events. Adverse events and changes in fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (PPG), 2-hour PPG excursion and weight were analysed according to previous GLP-1 RA regimen. RESULTS Switching to iGlarLixi in all subgroups resulted in significantly greater reductions in HbA1c and proportions of participants reaching HbA1c <7 % (including with no documented hypoglycaemia) at Week 26 compared with continued GLP-1 RA treatment. Switching to iGlarLixi also led to significantly greater reductions in FPG, 2-hour PPG, and 2-hour PPG excursion, irrespective of previous GLP-1 RA regimen. Rates of hypoglycaemia were low, but slightly higher in those who switched to iGlarLixi for all subgroups. Modest weight gain was seen with iGlarLixi, irrespective of previous GLP-1 RA regimen. CONCLUSIONS Switching to iGlarLixi improved glycaemic control, regardless of screening HbA1c or previous GLP-1 RA type, offering a simple, efficacious and well-tolerated treatment intensification option for people with T2D inadequately controlled by GLP-1 RAs and OADs.

Abstract
Eating behaviors are influenced by the reinforcing properties of foods that can favor decisions driven by reward incentives over metabolic needs. These food reward-motivated behaviors are modulated by gut-derived peptides such as ghrelin and glucagon-like peptide-1 (GLP-1) that are well-established to promote or reduce energy intake, respectively. In this review we highlight the antagonizing actions of ghrelin and GLP-1 on various behavioral constructs related to food reward/reinforcement, including reactivity to food cues, conditioned meal anticipation, effort-based food-motivated behaviors, and flavor-nutrient preference and aversion learning. We integrate physiological and behavioral neuroscience studies conducted in both rodents and human to illustrate translational findings of interest for the treatment of obesity or metabolic impairments. Collectively, the literature discussed herein highlights a model where ghrelin and GLP-1 regulate food reward-motivated behaviors via both competing and independent neurobiological and behavioral mechanisms.

Abstract
AIMS Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are the recommended first injectable therapy in type 2 diabetes. However, long-term persistence is suboptimal and partly attributable to gastrointestinal tolerability, particularly during initiation/escalation. Gradual titration of fixed-ratio combination GLP-1 RA/insulin therapies may improve GLP-1 RA gastrointestinal tolerability. We compared gastrointestinal adverse event (AE) rates for iGlarLixi versus GLP-1 RAs during the first 12 weeks of therapy, including a sensitivity analysis with IDegLira. MATERIALS AND METHODS The PICO framework was used to identify studies from MEDLINE, EMBASE and CENTRAL searches using a proprietary, web-based, standardized tool with single data extraction. Gastrointestinal AEs were modelled using a Bayesian network meta-analysis (NMA), using fixed and random effects for each recommended dose (treatment-specific NMA) and class (drug-class NMA). RESULTS Treatment-specific NMA included 17 trials (n = 9030; 3665 event-weeks). Nausea rates were significantly lower with iGlarLixi versus exenatide 10 μg twice daily (rate ratio: 0.32; 95% credible interval: 0.15, 0.66), once-daily lixisenatide 20 μg (0.35; 0.24, 0.50) and liraglutide 1.8 mg once daily (0.48; 0.23, 0.98). Rates were numerically, but not statistically, lower versus once-weekly semaglutide 1 mg (0.60; 0.30, 1.23) and dulaglutide 1.5 mg (0.60; 0.29, 1.26), and numerically, but not statistically, higher versus once-weekly exenatide (1.91; 0.91, 4.03). Sensitivity analysis results were similar. In a naïve, pooled analysis, vomiting was lower with iGlarLixi versus other GLP-1 RAs. CONCLUSIONS During the first 12 weeks of treatment, iGlarLixi was generally associated with less nausea and vomiting than single-agent GLP-1 RAs. Enhanced gastrointestinal tolerability with fixed-ratio combinations may favour treatment persistence.
