Efficacy of vitamin D supplementation on glycaemic control in type 2 diabetes: An updated systematic review and meta-analysis of randomized controlled trials.

AIM: To assess the effects of vitamin D interventions on glycaemic control in subjects with type 2 diabetes (T2D). METHODS: We searched PubMed, EMBASE, Web of Science and the Cochrane Library for relevant studies. Serum 25(OH)D, fasting blood glucose (FBG), HbA1c, fasting insulin and Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) were analysed. RESULTS: We identified 39 randomized controlled trials involving 2982 subjects. Results showed a significant decline in the vitamin D group, as shown by the FBG weighted mean difference (WMD; -0.49 [95% confidence interval {CI}: -0.69 to -0.28] mmol/L), HbA1c (WMD -0.30% [95% CI: -0.43 to -0.18]), HOMA-IR (WMD -0.39 [95% CI -0.64 to -0.14]) and insulin (WMD -1.31 [95% CI: -2.06 to -0.56] µIU/mL). Subgroup analyses indicated that the effects of vitamin D supplementation on glycaemic control depend on the dosage and duration of supplementation, baseline 25(OH)D levels and the body mass index of patients with T2D. CONCLUSIONS: Vitamin D supplementation can significantly reduce serum FBG, HbA1c, HOMA-IR and fasting insulin levels in T2D patients; the effects were especially prominent when vitamin D was given in a short-term, high dosage to patients with a vitamin D deficiency, who were overweight, or had an HbA1c of 8% or higher at baseline. Our study suggests that vitamin D supplements can be recommended as complementary treatment for T2D patients.

The Effect of COVID-19 Lockdown Among Adolescents with Type 1 Diabetes: A Systematic Review and Meta-Analysis.

OBJECTIVE: The aim of this study was to assess how the lockdown of the COVID-19 pandemic had affected the glycaemic control of adolescents aged 10-19 with type 1 diabetes. METHODS: A comprehensive search of literature was performed in PubMed, Scopus, Web of Science, and ProQuest. Published articles up to September 2022 were included. The Glucose Monitoring Index (GMI) and HbA1c level were defined as outcome variables. Average glucose level was found to be a common variable in both HbA1c levels and GMI; therefore, HbA1c and GMI were converted to average glucose (mg/dL) using appropriate formulas. Studies reported the outcomes in two or three periods (pre-lockdown, lockdown, and post-lockdown) were included in the analysis. A paired wise meta-analysis was performed among the studies that reported all three periods. Homogeneity across studies was assessed using I2 statistic. RESULT: Fourteen studies were included in the study. The pooled average glucose during the lockdown decreased to 166.9 mg/dL (95% CI, 153.78, 180.02) from 205.793 mg/dL (95% CI, 188.412, 223.173) during the pre-lockdown period, then it increased to 204.23 mg/dL (95% CI, 186.17, 222.29) during the post-lockdown period. A paired wise meta-analysis indicated a reduction in average glucose levels. However, it was not statistically significant, possibly due to the small number of studies that reported data from all three periods. CONCLUSION: Although the descriptive analysis of our study showed that the lockdown had affected (decreased) the average glucose level among adolescents with type 1 diabetes, this was not statistically significant in the pooled analysis.

Metformin continuation post-metabolic bariatric surgery and relapse of diabetes.

AIM: To evaluate the association of metformin continuation with relapse of diabetes after metabolic bariatric surgery (MBS) in patients with type 2 diabetes and obesity who achieved an HbA1c level of less than 6.5%. MATERIALS AND METHODS: This observational, retrospective cohort study included Clalit Health Service members aged 24 years or older with obesity and diabetes, who were treated with metformin, underwent MBS during 2005-2020 and achieved an HbA1c level of less than 6.5% up to 6 months after surgery (index date). Patients who continued metformin treatment (> 2 prescriptions filled, n = 122) after the index date were matched (1:2) on age, sex and HbA1c level at index date and compared with those who stopped treatment (no filled prescriptions, n = 244). The outcome was relapse of diabetes as measured by an HbA1c level of 6.5% or higher (yes/no). RESULTS: The two matched groups maintained a mean HbA1c level of less than 6.5% during the follow-up (mean ~ 5 years). An adjusted Cox proportional hazards model revealed no significant association of metformin continuation after MBS with relapse of diabetes (adjusted hazard ratio = 1.70, 95% confidence interval: 0.98-2.94). No significant differences were observed between the two groups in weight loss and filled prescriptions for other diabetes medications during the follow-up period. CONCLUSIONS: Among individuals living with obesity and diabetes who achieved diabetes remission post-MBS, metformin continuation was not associated with relapse of diabetes. This lack of an association indicates that metformin did not provide an additional benefit for maintaining glycaemic control or weight reduction during an average of 5 years postsurgery.

Deterioration of Vestibular Motion Perception: A Risk Factor for Postural Instability and Falls in Elderly With Type 2 Diabetes.

AIMS: To assess whether impaired vestibular perception of self-motion is a risk factor for unsteadiness and falls in elderly patients with type 2 diabetes (T2D). MATERIALS AND METHODS: 113 participants (65-75 years old) with T2D underwent tests of roll and pitch discrimination, postural stability (Berg Balance Scale, Modified Romberg Test, and quantitative posturography), clinical examination and blood chemistry analyses. Falls 1-year after enrolment were self-reported. We performed cluster analysis based on the values of the vestibular motion thresholds, and logistic stepwise regression to compare the clinical-biochemical parameters between clusters. RESULTS: We identified two clusters (VC1 n = 65 and VC2 n = 48 participants). VC2 had significantly (p < 0.001) higher (poorer) thresholds than VC1: mean pitch threshold 1.62°/s (95% CI 1.48-1.78) in VC2 and 0.91°/s (95% CI 0.84-0.98) in VC1, mean roll threshold 1.34°/s (95% CI 1.21-1.48) in VC2 and 0.69°/s (95% CI 0.64-0.74) in VC1. Diabetes duration was significantly (p = 0.024) longer in VC2 (11.96 years, 95% CI 9.23-14.68) than in VC1 (8.37 years, 95% CI 6.85-9.88). Glycaemic control was significantly (p = 0.014) poorer in VC2 (mean HbA1c 6.74%, 95% CI 6.47-7.06) than in VC1 (mean HbA1c 6.34%, 95% CI 6.16-6.53). VC2 had a significantly higher incidence of postural instability than VC1, with a higher risk of failing the Modified Romberg Test C4 (RR = 1.57, χ2 = 5.33, p = 0.021), reporting falls during follow-up (RR = 11.48, χ2 = 9.40, p = 0.002), and greater postural sway in the medio-lateral direction (p < 0.025). CONCLUSIONS: Assessing vestibular motion thresholds identifies individuals with T2D at risk of postural instability due to altered motion perception and guides vestibular rehabilitation.

The impact of vildagliptin as an add-on therapy on matrix metalloproteinase-14 levels, liver stiffness and subclinical atherosclerosis in adolescents with type 1 diabetes and non-alcoholic steatohepatitis: A randomized controlled trial.

AIM: Many patients with type 1 diabetes mellitus (T1DM) met the histological criteria for non-alcoholic steatohepatitis (NASH), which leads to cardiovascular disease morbidity and mortality. Matrix metalloproteinase-14 (MMP-14) is involved in cardiovascular disease and atherosclerosis. OBJECTIVES: To assess the impact of oral dipeptidyl peptidase-4 inhibitor, vildagliptin, as adjunctive therapy on NASH in adolescents with T1DM and its effect on glycaemic control, MMP-14 levels and carotid intima media thickness (CIMT). METHODS: Sixty adolescents with T1DM and NASH were randomly assigned to receive oral vildagliptin (50 mg once daily) for 6 months or not. Glycated haemoglobin, lipid profile, hepatic steatosis index, triglyceride glucose (TyG) index and MMP-14 levels were assessed. Transient elastography with controlled attenuation parameter (CAP) was performed together with measuring CIMT. RESULTS: By transient elastography, 12 (20%) patients with T1DM with NASH had elevated liver stiffness ≥7 kPa (F2 stage or higher). Baseline MMP-14 was positively correlated to insulin dose (p = 0.016), triglycerides and TyG index, CIMT, liver stiffness and CAP levels among the studied patients (p < 0.001 for all). After 6 months, patients with T1DM on vildagliptin therapy had significantly lower glycated haemoglobin, lipid profile, hepatic steatosis index and TyG index, as well as MMP-14 (p < 0.001). CIMT, liver stiffness and CAP were significantly decreased post-therapy compared with baseline levels and compared with the control group (p < 0.001). Vildagliptin was safe and well-tolerated. CONCLUSIONS: Administration of vildagliptin for adolescents with T1DM and NASH improved glycaemic control, dyslipidaemia and MMP-14 levels and decreased liver stiffness and CIMT; hence, reducing subclinical atherosclerosis and disease progression.

Continuous ketone monitoring: Exciting implications for clinical practice.

Diabetic ketoacidosis (DKA) is a life-threatening complication usually affecting people with type 1 diabetes (T1D) and, less commonly, people with type 2 diabetes. Early identification of ketosis is a cornerstone in DKA prevention and management. Current methods for ketone measurement by people with diabetes include capillary blood or urine testing. These approaches have limitations, including the need to carry testing strips that have a limited shelf life and a requirement for the user to initiate a test. Recent studies have shown the feasibility of continuous ketone monitoring (CKM) via interstitial fluid with a sensor inserted subcutaneously employing an enzymatic electrochemical reaction. Ketone readings can be updated every 5 minutes. In the future, one would expect that commercialized devices will incorporate alarms linked with standardized thresholds and trend arrows. Ideally, to minimize the burden on users, CKM functionality should be integrated with other devices used to implement glucose management, including continuous glucose monitors and insulin pumps. We suggest CKM provision to all at risk of DKA and recommend that the devices should be worn continuously. Those who may particularly benefit are individuals who have T1D, are pregnant, on medications such as sodium-glucose linked transporter (SGLT) inhibitors that increase DKA, people with recurrent DKA, those with T1D undertaking high intensity exercise, are socially or geographically isolated, or those on low carbohydrate diets. The provision of ketone profiles will provide important clinical insights that have previously been unavailable to people living with diabetes and their healthcare professionals.

PIONEER REAL UK: A Multi-Centre, Prospective, Real-World Study of Once-Daily Oral Semaglutide Use in Adults with Type 2 Diabetes.

INTRODUCTION: Oral semaglutide provides an alternative to injectable glucagon-like peptide-1 receptor agonists (GLP-1RAs) for treatment of type 2 diabetes (T2D). The PIONEER REAL studies evaluate clinical outcomes of oral semaglutide treatment of T2D in a real-world setting. PIONEER REAL UK focused on adults living with T2D in the UK. METHODS: The multi-centre, prospective and non-interventional single-arm study enrolled 333 participants and followed them for 34-44 weeks. Participants were treated as part of routine clinical practice and had not been previously treated with injectable glucose-lowering medication. The primary endpoint was change in glycated haemoglobin (HbA1C) from baseline to end of study (EOS). Secondary endpoints included change in body weight, proportion of participants with HbA1C < 7% (53 mmol/mol) at EOS and proportion of participants with ≥ 1%-point HbA1C reduction and body weight reduction of ≥ 3% or ≥ 5% at EOS. Treatment satisfaction was assessed by Diabetes Treatment Satisfaction Questionnaire (DTSQ) status and change. RESULTS: Of 333 participants, 299 completed the study and 227 were on treatment at EOS. People treated with oral semaglutide experienced significantly reduced HbA1C by an estimated change of - 1.1%-points (95% CI - 1.27 to - 0.96; P < 0.0001) or - 12.2 mmol/mol (CI - 13.87 to - 10.47; P < 0.0001). Estimated change in body weight was - 4.8 kg (CI - 5.47 to - 4.12; P < 0.0001). At EOS, an HbA1C level < 7% (53 mmol/mol) was recorded in 46.3% of participants. A ≥ 1%-point reduction in HbA1C combined with a ≥ 3% reduction in body weight was observed in 36.4% of participants, and 27.1% had a ≥ 1%-point reduction in HbA1C and a ≥ 5% body weight reduction. Treatment satisfaction improved significantly during the study. No new safety concerns or cases of severe hypoglycaemia were reported. CONCLUSION: People living with T2D in the UK experienced a meaningful decrease in HbA1C and body weight after initiation of oral semaglutide treatment. No new safety issues were observed.

PIONEER REAL UK investigated the use of a tablet form of the medicine semaglutide in people living with type 2 diabetes in the UK. The purpose was to determine how well the tablet works for blood sugar control and weight loss in everyday clinical practice. The study followed 333 participants whose doctors had given them semaglutide tablets. Their blood sugar levels and body weight were measured before and after taking the semaglutide tablet for 34­44 weeks. The participants were also asked to fill out questionnaires about their treatment satisfaction and how it changed when taking the semaglutide tablet. The participants' blood sugar levels dropped a lot, and body weight was lowered by an average of 4.8 kg during the 34­44 weeks of the study. The participants were also more satisfied with their treatment at the end of the study than before taking the semaglutide tablet. Doctors treating the participants found the treatment to be a success in more than two-thirds of participants. The study also found that the semaglutide tablet was not associated with cases of too low blood sugar and was generally well tolerated. In summary, the semaglutide tablet is a good option for people living with type 2 diabetes who need better blood sugar control and would benefit from weight loss. The treatment is generally well tolerated, and people are very satisfied with it.

Glycaemic and weight effects of metabolic surgery or semaglutide in diabetes dosage for patients with type 2 diabetes.

AIM: To compare weight and glucometabolic outcomes of semaglutide and metabolic and bariatric surgery (MBS) for patients with type 2 diabetes and obesity. MATERIALS AND METHODS: Patients treated with either semaglutide for a duration of ≥2 years or MBS in Sweden were identified within the Scandinavian Obesity Surgery Registry and the National Diabetes Registry and matched in a 1:1-2 ratio using a propensity score matching with a generalized linear model, including age, sex, glycated haemoglobin before treatment, duration of type 2 diabetes, use of insulin, presence of comorbidities and history of cancer, with good matching results but with a remaining imbalance for glomerular filtration rate and body mass index, which were then adjusted for in the following analyses. Main outcomes were weight loss and glycaemic control. RESULTS: The study included 606 patients in the surgical group matched to 997 controls who started their treatment from 2018 until 2020. Both groups improved in weight and glucometabolic control. At 2 years after the intervention, mean glycated haemoglobin was 42.3 ± 11.18 after MBS compared with 50.7 ± 12.48 after semaglutide treatment (p < 0.001) with 382 patients (63.0%) and 139 (13.9%), respectively, reaching complete remission without other treatment than the intervention (p < 0.001). Mean total weight loss reached 26.4% ± 8.83% after MBS compared with 5.2% ± 7.87% after semaglutide (p < 0.001). CONCLUSION: Semaglutide and MBS were both associated with improvements in weight and improved glycaemic control at 2 years after the start of the intervention, but MBS was associated with better weight loss and glucometabolic control.

Effectiveness of lifestyle interventions for glycaemic control among adults with type 2 diabetes in West Africa: a systematic review and meta-analysis protocol.

BACKGROUND: Lifestyle interventions are key to the control of diabetes and the prevention of complications, especially when used with pharmacological interventions. This protocol aims to review the effectiveness of lifestyle interventions in relation to nutrition and physical activity within the West African region. This systematic review and meta-analysis seeks to understand which interventions for lifestyle modification are implemented for the control of diabetes in West Africa at the individual and community level, what evidence is available on their effectiveness in improving glycaemic control and why these interventions were effective. METHODS: We will review randomised control trials and quasi-experimental designs on interventions relating to physical activity and nutrition in West Africa. Language will be restricted to English and French as these are the most widely spoken languages in the region. No other filters will be applied. Searching will involve four electronic databases - PubMed, Scopus, Africa Journals Online and Cairn.info using natural-language phrases plus reference/citation checking. Two reviewers will independently screen results according to titles and abstracts against the inclusion and exclusion criteria to identify eligible studies. Upon full-text review, all selected studies will be assessed using Cochrane's Collaboration tool for assessing the risk of bias of a study and the ROBINS-I tool before data extraction. Evidence will be synthesised narratively and statistically where appropriate. We will conduct a meta-analysis when the interventions and contexts are similar enough for pooling and compare the treatment effects of the interventions in rural to urban settings and short term to long term wherever possible. DISCUSSION: We anticipate finding a number of studies missed by previous reviews and providing evidence of the effectiveness of different nutrition and physical activity interventions within the context of West Africa. This knowledge will support practitioners and policymakers in the design of interventions that are fit for context and purpose within the West African region. SYSTEMATIC REVIEW REGISTRATION: This systematic review has been registered in the International Prospective Register for Systematic Reviews - PROSPERO, with registration number CRD42023435116. All amendments to this protocol during the process of the review will be explained accordingly.

Comparative Effects of Diabetes Self-Management Programs on Type 2 Diabetes Clinical Outcomes: A Systematic Review and Network Meta-Analysis.

AIMS: This systematic review and network meta-analysis compared the effects of various diabetes self-management programs: Diabetes Self-Management Education (DSME), Diabetes Self-Management Support (DSMS), and Diabetes Self-Management Education and Support (DSMES). METHODS: We searched four electronic databases for eligible articles up to March 1, 2023. Only randomized controlled trials investigating the effects of DSME, DSMS, or DSMES on glycated haemoglobin (HbA1c) level, fasting blood glucose (FBG), total cholesterol (TC), systolic blood pressure (SBP), and diastolic blood pressure (DBP) in adults with type 2 diabetes were included. Cochrane Risk of Bias 2.0 tool was used to assess each study quality, and Confidence in Network Meta-Analysis was applied to evaluate the certainty of the evidence. Data were pooled with a random-effects model under a frequentist framework. RESULTS: A total of 108 studies encompassing 17,735 participants (mean age 57.4 years) were analysed. DSMES, compared with usual care, significantly reduced HbA1c level (mean difference = -0.61%, 95% confidence interval [CI] = -0.74 to -0.49; certainty of evidence = moderate), FBG (-23.33 mg/dL; -31.33 to -15.34; high), TC (-5.62 mg/dL; -8.69 to -2.55; high), SBP (-3.05 mmHg; -5.20 to -0.91; high), and DBP (-2.15 mmHg; -3.36 to -0.95; high). Compared with DSME, DSMES showed significantly greater improvements in HbA1c levels (-0.23%; -0.40 to -0.07; high) and DBP (-1.82 mmHg; -3.47 to -0.17; high). DSMES was ranked as the top treatment for improving diabetes clinical outcomes (0.82-0.97) in people with type 2 diabetes. CONCLUSIONS: DSMES, in people with type 2 diabetes, yields the greatest improvement in the key clinical outcomes of HbA1c, fasting blood glucose, and blood pressure levels. Healthcare providers should incorporate the DSMES approach into their daily care routines. Approximately 30% of the studies reviewed raised some concerns about their quality, underscoring the need for high-quality studies in this area.

A whole-food, plant-based intensive lifestyle intervention improves glycaemic control and reduces medications in individuals with type 2 diabetes: a randomised controlled trial.

AIMS/HYPOTHESIS: We conducted the largest and longest clinical trial comparing a whole-food, plant-based intervention with standard medical care (SMC) in individuals with type 2 diabetes. METHODS: We randomised (parallel-arm; computerised 1:1 randomisation ratio) 169 adults aged 18-75 years with type 2 diabetes in the Marshall Islands to an intensive whole-food, plant-based intervention with moderate exercise (PB+Ex) or SMC for 24 weeks. The PB+Ex intervention included 12 weeks of meals, exercise sessions and group classes. Primary outcomes were glycaemic control (HbA1c, glucose, insulin and HOMA-IR) and glucose-lowering medication use. Secondary outcomes included lipids, blood pressure, heart rate and C-reactive protein. Only lab analysts were blinded. RESULTS: Compared with SMC (n=90 randomised; n=70 analysed), the PB+Ex (n=79 randomised; n=66 analysed) intervention decreased HbA1c by an additional 14 mmol/mol (1.3%) at week 12 (-22 vs -7 mmol/mol [-2.0% vs -0.7%]; p<0.0001) and 8 mmol/mol (0.7%) at week 24 (-16 vs -8 mmol/mol [-1.4% vs -0.7%]; p=0.01). Concomitantly, 63% of medicated PB+Ex participants reduced their glucose-lowering medications (vs 24%; p=0.006), and 23% of PB+Ex participants with a baseline HbA1c <75 mmol/mol (<9%) achieved remission. Additionally, the PB+Ex intervention reduced weight (-2.7 kg; p<0.0001), C-reactive protein (-11 nmol/l; p=0.005) and cardiovascular medication use compared with SMC. At intermediate timepoints, it improved glucose, insulin, HOMA-IR, cholesterol, triglycerides and heart rate, but not at week 24. CONCLUSIONS/INTERPRETATION: A whole-food, plant-based lifestyle intervention was more effective for improving glycaemic control than SMC. It also reduced the need for diabetes and cardiovascular medications and induced diabetes remission in some participants. Therefore, it is an effective, evidence-based lifestyle option for individuals with type 2 diabetes.

The interdependence of targets for continuous glucose monitoring outcomes in type 1 diabetes with automated insulin delivery.

AIM: The aim was to determine the interdependence of targets for glucose management indicator (GMI), time within the ranges of 70-180 mg/dL (TIR) and 70-140 mg/dL (time in tight glucose range [TITR]), time above 180 mg/dL (TA180) and 250 mg/dL (TA250) and time below 70 mg/dL (TB70) and 54 mg/dL (TB54) and its implications for setting targets in automated insulin delivery (AID). MATERIALS AND METHODS: Real-world data from individuals with type 1 diabetes using the 780G system were used to calculate the receiver operating characteristic curves and establish interdependent targets for time in ranges based on several GMI benchmarks. Correlation, regression and principal component analysis were used to determine their association and dimensionality. RESULTS: In individuals aged >15 years (n = 41 692), a GMI <6.5% required targets of >81%, >58%, <15% and <1.9% for TIR, TITR, TA180 and TA250, respectively, with high sensitivity, specificity and accuracy (>90%), whereas these values were poor for time in hypoglycaemia and GMI, which had a modest correlation (-0.21 to -0.43). Two dimensions emerged: (1) GMI, TIR, TITR, TA180 and TA250, and (2) TB70 and TB54, explaining 95% of total variability. GMI (or TIR) and TB70 explained >81% of the variability in the remaining continuous glucose monitoring (CGM) metrics, providing accurate predictions. Individuals aged ≤15 years (n = 14 459) showed similar results. CONCLUSION: We developed a methodology to establish interdependent CGM targets for therapies with CGM data outputs. In AID with the 780G system, a GMI <7% requires time in ranges close to consensus targets. Targets for GMI, TIR, TITR, TA180 and TA250 could be reduced to targets for GMI or TIR, whereas targets for time in hypoglycaemia are not inherently tied to GMI/TIR targets.

Glycaemic control metrics and metabolic dysfunction-associated steatotic liver disease in children and adolescents with type 1 diabetes.

AIM: The aim was to examine the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), a risk factor for atherosclerotic cardiovascular disease, and its association with glycaemic control metrics in children and adolescents with type 1 diabetes (T1D). MATERIALS AND METHODS: We enrolled 244 children and adolescents with T1D (115 girls, mean age: 16.2 ± 3.2 years). The diagnosis of MASLD was defined by the presence of hepatic steatosis on ultrasonography in combination with at least one of five common cardiometabolic risk factors. Metrics of short-term and long-term glycaemic control, blood pressure, lipids, anthropometric characteristics and three genetic variants strongly related to MASLD susceptibility (rs738409 [patatin-like phospholipase domain-containing 3], rs58542926 [transmembrane 6 superfamily member 2] and rs1260326 [glucokinase regulator]) were assessed. Characteristics of these subjects with and without MASLD were compared using the unpaired Student t test, Mann-Whitney test or χ2 test as appropriate. Logistic regression analyses were performed to determine the main independent predictors of MASLD. RESULTS: The prevalence of MASLD was 27.5% in children and adolescents with T1D. Blood pressure, total cholesterol, low-density lipoprotein (LDL) cholesterol, non-high-density lipoprotein cholesterol, HbA1c and time above range (TAR) were significantly higher in subjects with MASLD than in those without MASLD. Mean HbA1c values from diabetes onset (adjusted odds ratio [OR]: 1.703, 95% confidence interval [CI]: 1.040-2.787, p = 0.034), TAR (adjusted OR: 1.028, 95% CI: 1.009-1.047, p = 0.006) and plasma LDL cholesterol (adjusted OR: 1.045, 95% CI: 1.013-1.078, p = 0.004) were independently associated with the presence of MASLD. CONCLUSIONS: MASLD is a common condition in children and adolescents with T1D. The mean HbA1c values from diabetes onset, TAR and LDL cholesterol levels were the independent predictors of MASLD.

Impact of baseline characteristics on the efficacy of once-weekly subcutaneous semaglutide among participants with type 2 diabetes: A post hoc analysis of SUSTAIN China.

AIMS: To investigate the impact of baseline characteristics on the efficacy of once-weekly subcutaneous semaglutide 0.5 and 1.0 mg in participants with type 2 diabetes (T2D) from the SUSTAIN China trial. METHODS: In this post hoc analysis, data for semaglutide 0.5 and 1.0 mg versus sitagliptin 100 mg were analysed in the total (n = 868) and Chinese-only (n = 605) populations. Changes from baseline to end of treatment (EOT) in glycated haemoglobin (HbA1c) and body weight were analysed by baseline age, sex, body mass index, HbA1c, diabetes duration, and homeostatic model assessment of ß-cell function (HOMA-ß) tertile. Proportions of participants achieving HbA1c <7.0% (53 mmol/mol) by baseline HbA1c, change from baseline to EOT in standard deviation of seven-point self-monitored plasma glucose (SMPG), derived time-in-range (dTIR) of seven-point SMPG at Week 30, and HOMA-ß ratio to baseline at Week 30 were assessed for both populations. RESULTS: In both populations the efficacy of once-weekly subcutaneous semaglutide 0.5 and 1.0 mg versus sitagliptin was not significantly affected by most of the baseline characteristics studied. The proportion of participants achieving the target HbA1c <7% was not affected by baseline HbA1c (pinteraction > 0.05). SMPG fluctuation and dTIR indicated less glucose variability in participants treated with semaglutide 0.5 and 1.0 mg versus sitagliptin, and the HOMA-ß ratios to baseline at EOT were greater with semaglutide 0.5 and 1.0 mg versus sitagliptin (p < 0.05). CONCLUSIONS: These results support the effectiveness of once-weekly subcutaneous semaglutide 0.5 and 1.0 mg across a broad range of baseline characteristics, in participants with T2D from SUSTAIN China.

Cofrogliptin once every 2 weeks as add-on therapy to metformin versus daily linagliptin in patients with type 2 diabetes in China: A randomized, double-blind, non-inferiority trial.

AIM: We evaluated the efficacy and safety of cofrogliptin, a novel dipeptidyl peptidase-4 inhibitor taken once every 2 weeks (Q2W), compared with linagliptin (taken daily) in patients with type 2 diabetes inadequately controlled on metformin in China. MATERIALS AND METHODS: In this phase 3 randomized, double-blind, active-controlled, multicentre study, patients were randomly assigned 1:1:1 to receive cofrogliptin 10 mg Q2W, cofrogliptin 25 mg Q2W, or linagliptin 5 mg daily, all as an add-on treatment to metformin, for 24 weeks. Eligible patients could enter an open-label extension period and receive cofrogliptin 25 mg Q2W for an additional 28 weeks. The primary endpoint was change in glycated haemoglobin from baseline to 24 weeks, with a non-inferiority margin of 0.4% for cofrogliptin versus linagliptin treatment. RESULTS: Overall, 465 patients entered the 24-week treatment period (median age: 57.0 years). The least-squares mean (standard error) change in glycated haemoglobin from baseline to week 24 was -0.96 (0.063), -0.99 (0.064) and -1.07 (0.065) for the cofrogliptin 10 mg, cofrogliptin 25 mg and linagliptin 5 mg groups, respectively. The between-group difference met the predefined margin for non-inferiority of cofrogliptin (10 and 25 mg) versus linagliptin treatment. The incidence of common adverse events (≥5% patients) during the 24-week treatment period was similar between treatment groups. There were no serious hypoglycaemic events. CONCLUSION: In Chinese patients with type 2 diabetes inadequately controlled on metformin, the glucose-lowering effect of cofrogliptin (Q2W) was non-inferior to linagliptin (daily), with a similar safety profile maintained over 52 weeks of treatment.

Effectiveness of Mindfulness-Based Interventions with Respect to Psychological and Biomedical Outcomes in Young People with Type 1 Diabetes: A Systematic Review.

BACKGROUND: Type 1 diabetes is a chronic disease especially affecting young people. Mindfulness-based psychological interventions might reduce emotional symptoms post-diagnosis, but the evidence is limited. OBJECTIVES: This systematic review aimed to evaluate the effectiveness of mindfulness interventions on psychological well-being and biomedical variables in young people with type 1 diabetes. METHODS: A systematic review of trials was conducted that involved a bibliographic search in electronic databases (Web of Science, MEDLINE, SciELO, Scopus, PsycINFO, and Cochrane Library) considering studies published between 2013 and 2024. RESULTS: A total of 434 records were identified, of which 252 underwent selection according to title and abstract, leaving 32 that were evaluated for eligibility and 7 included in this review. From Google Scholar, six more studies were identified and evaluated, and two were selected. Finally, nine studies were subjected to full reading and a detailed analysis of the inclusion criteria. A total of 66.6% of the studies were evaluated as having a methodological quality of moderate or optimal, but the samples analysed tended to be small, and only two articles carried out short-term follow-up evaluations. CONCLUSIONS: Mindfulness-based interventions, upon reviewing the preliminary results, may be posited as a viable strategy to enhance psychological (anxiety, diabetes distress, perceived stress, depression, self-efficacy, psychological well-being, and quality of life) and biomedical outcomes (glycaemic control, blood glucose levels, and diastolic blood pressure) for type 1 diabetes in young people. Although promising, further research is required to improve the quality, methodology, and design of studies.

Real-world evaluation of the effects of tirzepatide in patients with type 2 diabetes mellitus.

AIMS: Tirzepatide is a first-in-class combination glucose-dependent insulinotropic polypeptide (GIP) receptor agonist and glucagon-like peptide 1 receptor agonist (GLP1-RA) approved for treatment of adults with type 2 diabetes mellitus (T2DM) and chronic weight management. The aim of this analysis was to assess the real-world efficacy of tirzepatide in patients with T2DM. METHODS: This retrospective observational study evaluated patients with T2DM from a large urban academic medical centre who received at least 3 months of continuous tirzepatide treatment. The primary outcome was change in A1C from following tirzepatide treatment. Secondary outcomes included change in body weight and body mass index (BMI) after tirzepatide was initiated. RESULTS: A total of 1896 patient charts were reviewed, and 612 patients were evaluated for the primary outcome. Over a median time period of 10.4 months, treatment with tirzepatide resulted in a mean A1C reduction of 1.02 ± 1.48% (p < 0.001). A total of 570 patients were evaluated for the secondary outcomes. Tirzepatide was associated with a mean reduction in body weight of 7.3 ± 9.3 kg (p < 0.001) and a mean reduction in BMI of 2.5 kg/m2. Greater A1C lowering and weight loss was observed in patients without prior GLP1-RA treatment compared to those switched to tirzepatide from GLP1-RA. CONCLUSIONS: In a real-world population of US patients with T2DM, tirzepatide was associated with clinically and statistically significant reductions in A1C and body weight. Greater reductions in both A1C and body weight were observed among patients who were GLP1-RA naïve compared to patients switched from GLP1-RA to tirzepatide.

The association of type 2 diabetes-related characteristics with fracture risk at different sites.

AIM: To determine the association of diabetes-related characteristics with fractures at different sites in individuals with type 2 diabetes (T2D). MATERIALS AND METHODS: We conducted a cohort study using the Clinical Practice Research Datalink (CPRD) GOLD. Patients aged over 30 years with T2D were identified within the CPRD. Patients were followed from the start of diabetes treatment until the end of data collection, death, or the occurrence of a fracture. Cox proportional hazards models were used to estimate the hazard ratios for the association of the individual characteristics (diabetes duration, glycated haemoglobin [HbA1c] level, and microvascular complications) with fracture risk, adjusted for demographics, comorbidities and comedication. RESULTS: A diabetes duration of >10 years was associated with an increased risk of any fracture and major osteoporotic fractures (MOFs), while a diabetes duration of >8 years was associated with an increased hip fracture risk, compared to a duration <2 years. An HbA1c level <6% was associated with an increased fracture risk compared to HbA1c values of 6% to <7%. The presence of one or two microvascular complications was associated with an increased risk of any fracture and MOFs and the presence of two microvascular complications was associated with an increased hip fracture risk, compared to no microvascular complications. CONCLUSION: In conclusion, our study shows that a diabetes duration of 10 years or more, strict glycaemic control resulting in HbA1c levels below 6%, and/or the presence of at least one microvascular complication increased the risk of any fracture, hip fractures, MOFs, and humerus fractures, but not ankle, scapula or skull fractures.

Children and adolescent with suboptimal control of type 1 diabetes improve during the first 2 years on automated insulin delivery system.

AIMS: This study investigates the influence of the automated insulin delivery system (AID) on glycaemic control in children and adolescents with type 1 diabetes (T1D) who do not reach optimal glycaemic control with traditional treatment options. MATERIALS AND METHODS: All the patients aged 7 to 16 years with T1D who initiated the AID system between 24 October 2020 and 5 January 2022 in the Helsinki University Hospital and had haemoglobin A1C (HbA1c) levels above 53 mmol/mol/7.0% (N = 79) were included. Time in tight range (TITR), time in range (TIR), HbA1c, mean sensor glucose (SG) value, time below range (TBR) and SG coefficient of variance (CV) were measured at 0, 3, 12 and 24 months. The changes in the outcome measures between the time points were included in the analyses, and statistically significant level was p-value <0.01. RESULTS: After the initiation of AID, glycaemic control improved, and the effect lasted throughout the study period. Between 0 and 3 months, TITR and TIR increased (mean 11.7% [10.6], mean 18.1% [standard deviation [SD] 13.7], p < 0.001), whereas HbA1c and mean SG values decreased significantly (-8.3 mmol/mol [8.7]/-2.9% [2.9], p < 0.001, -1.8 mmol/L [1.7], p < 0.001). These effects were sustainable and were still visible at 12 and 24 months. CONCLUSIONS: Glycaemic control in patients not reaching treatment goals improved significantly after the initiation of the AID system, and the favourable effect lasted throughout the follow-up. AID treatment could be an option for also those paediatric patients with T1D who do not have good skills in diabetes management.
