Abstract
Introduction Semaglutide, a Glucagon-like Peptide-1 Receptor Agonist (GLP-1 RA), is often prescribed for managing type 2 diabetes, particularly in cases unresponsive to other hypoglycemic agents. Despite its popularity, the real-world efficacy and cost-effectiveness of Semaglutide relative to other treatments remain understudied. Objective This study aimed to examine the direct medical cost and consequences of adding Semaglutide to the treatment regimen for patients with type 2 diabetes in Saudi Arabia. Methods We conducted a single-center, retrospective review of Electronic Medical Records (EMRs) for adults with type 2 diabetes. Patients who had been on Semaglutide for at least three months were matched with those receiving alternative hypoglycemic therapies. Exclusions were made for patients with cancer, incomplete EMRs, or lacking prescription data. Investigated outcomes included changes in HbA1C levels and weight, and the direct costs comprised medications, clinic visits, and emergency care. Baseline adjustments were made through inverse probability treatment weighting, and uncertainty was assessed via bootstrapping with 10,000 replications. Results Out of 350 patients meeting the criteria, 116 were on Semaglutide. Predominantly females (62%), the cohort had an average age of 60 and a disease duration of 22 years. The difference in HbA1C (%) reductions between Semaglutide and non-Semaglutide users over 3,6, and 12 months were 0.154 (95% CI: -0.452-0.483), -0.031(95% CI: -0.754-0.239), -0.16(95% CI: -1.425-0.840), respectively. Semaglutide users did experience modest weight reductions ranging from 0.42 kg to 1.16 kg. The annual additional direct medical cost for Semaglutide was USD 4,086.82 (95% CI: $3,710.85 - $4,294.99). Conclusion Although Semaglutide induced modest weight reductions, it did not offer significant advantages in lowering HbA1C levels compared to other hypoglycemic treatments. These findings suggest the need for further research involving larger and more diverse cohorts to corroborate these findings.

Abstract
OBJECTIVES In Chile, > 900,000 people with type 2 diabetes mellitus (DM2) are controlled in the Cardiovascular Health Program (PSCV). Even though the PSCV includes a set of interventions for the control of patients with DM2, the results are still insufficient, generating a high human, economic, and social cost. This study aimed to identify and select new health technologies for the control of patients with DM2 not currently incorporated into the PSCV to be proposed as candidates for an economic evaluation in the Chilean context. METHODS For the identification of new health technologies, consultations with key informants and an umbrella review of updated scientific evidence were used as sources of information. In a second step, selection among those technologies was conducted based on the effectiveness of the intervention, target population, nature of the intervention, and international evidence of cost-effectiveness antecedents. RESULTS Key informants identified 12 candidate health technologies not currently incorporated into the PSCV. From the umbrella review, an additional 9 health technologies were identified that were not identified by the key informants. Of the 21 new health technologies identified, finally 8 health technologies were selected (structured group education, pedometer use, periodontal treatment, cognitive-behavioral therapy, telemonitoring, sitagliptin, canagliflozin, and insulin degludec). CONCLUSIONS The health technologies detected have a high potential to be studied through economic evaluations that allow guiding decision making around improving the health outcomes of patients with DM2 in Chile.

Abstract
While glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as semaglutide, are among the most effective drugs for treating people with type 2 diabetes (T2D), they are clinically under-utilised. Until recently, the only route for semaglutide administration was via subcutaneous injection. However, an oral formulation of semaglutide was recently licensed, with the potential to address therapy inertia and increase patient adherence to treatment, which is essential in controlling blood glucose and reducing complications. The availability of oral semaglutide provides a new option for both clinicians and patients who are reluctant to use an injectable agent. This has been of particular importance in addressing the challenge of virtual diabetes care during the COVID-19 pandemic, circumventing the logistical problems that are often associated with subcutaneous medication administration. However, there remains limited awareness of the clinical and economic value of oral semaglutide in routine clinical practice. In this article, we present our consensus opinion on the role of oral semaglutide in routine clinical practice and discuss its value in reducing the burden of delivering diabetes care in the post-COVID-19 pandemic period of chronic disease management.

Abstract
The scientific landscape of treatments for type 2 diabetes (T2D) has changed rapidly in the last decade with newer treatments becoming available. However, a large proportion of people with T2D are not able to achieve glycaemic goals because of clinical inertia. The majority of T2D management is in primary care, where clinicians (medical, nursing and pharmacist staff) play an important role in addressing patient needs and achieving treatment goals. However, management of T2D is challenging because of the heterogeneity of T2D and complexity of comorbidity, time constraints, guidance overload and the evolving treatments. Additionally, the current coronavirus disease pandemic poses additional challenges to the management of chronic diseases such as T2D, including routine access to patients for monitoring and communication. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are a class of agents that have evolved rapidly in recent years. These agents act in a glucose-dependent manner to promote insulin secretion and inhibit glucagon secretion, as well as enhancing satiety and reducing hunger. As a result, they are effective treatment options for people with T2D, achieving glycated haemoglobin reductions, weight loss and potential cardiovascular benefit, as monotherapy or as add-on to other glucose-lowering therapies. However, given the complexity of managing T2D, it is important to equip primary care clinicians with clear information regarding efficacy, safety and appropriate positioning of GLP-1 RA therapies in clinical practice. This review provides a summary of clinical and real-world evidence along with practical guidance, with the aim of aiding primary care clinicians in the initiation and monitoring of GLP-1 RAs to help ensure that desired outcomes are realised. Furthermore, a benefit/risk tool has been developed on the basis of current available evidence and guidelines to support primary care clinicians in selecting individuals who are most likely to benefit from GLP-1 RA therapies, in addition to indicating clinical situations where caution is needed.

Abstract
BACKGROUNDS Glucagon-like peptide-1 receptor agonist (GLP-1 RA) is probably one of more effective antidiabetic agents in treatment of type 2 diabetes mellitus (T2D). However, the heterogenicity in responses to GLP-1 RA may be potentially related to gut microbiota, although no human evidence has been published. This pilot study aims to identify microbial signatures associated with glycemic responses to GLP-1 RA. MATERIALS AND METHODS Microbial compositions of 52 patients with T2D receiving GLP-1 RA were determined by 16S rRNA amplicon sequencing. Bacterial biodiversity was compared between responders versus non-responders. Pearson's correlation and random forest tree algorithm were used to identify microbial features of glycemic responses in T2D patients and multivariable linear regression models were used to validate clinical relevance. RESULTS Beta diversity significantly differed between GLP-1 RA responders (n = 34) and non-responders (n = 18) (ADONIS, P = 0.004). The top 17 features associated with glycohemoglobin reduction had a 0.96 diagnostic ability, based on area under the ROC curve: Bacteroides dorei and Roseburia inulinivorans, the two microbes having immunomodulation effects, along with Lachnoclostridium sp. and Butyricicoccus sp., were positively correlated with glycemic reduction; Prevotella copri, the microbe related to insulin resistance, together with Ruminococcaceae sp., Bacteroidales sp., Eubacterium coprostanoligenes sp., Dialister succinatiphilus, Alistipes obesi, Mitsuokella spp., Butyricimonas virosa, Moryella sp., and Lactobacillus mucosae had negative correlation. Furthermore, Bacteroides dorei, Lachnoclostridium sp. and Mitsuokella multacida were significant after adjusting for baseline glycohemoglobin and C-peptide concentrations, two clinical confounders. CONCLUSIONS Unique gut microbial signatures are associated with glycemic responses to GLP-RA treatment and reflect degrees of dysbiosis in T2D patients.

Abstract
Abstract
Objectives
Primary objective of this study was to compare the overall health expenditures of patients with type 2 diabetes on sodium–glucose cotransporter-2 (SGLT2) inhibitors versus dipeptidyl peptidase-4 (DPP4) inhibitors.
Methods
Two cohorts of type 2 diabetes patients receiving either SGLT2 inhibitor with metformin or DPP4 inhibitor with metformin were identified from 2015 to 2016 Medical Expenditure Panel Survey (MEPS) data. Propensity score matching was used to balance cohorts based on socio-economic status, insulin utilization status, and the Charlson comorbidity score. Patients in SGLT2 inhibitor cohort were matched with patients in DPP4 inhibitor cohort using 1 : 2 ratio on the logit of propensity score using caliper width of 0.1 of the standard deviation of the logit of the propensity score. Expenditure variables were analysed using a generalized linear model with log link function and gamma distribution and adjusted for socio-economic variables. Unadjusted means were obtained using bootstrap.
Results
After propensity score matching, 240 patients were left in the sample with 80 patients in SGLT2 inhibitor cohort and 160 patients in DPP4 inhibitor cohort. Unadjusted average annual total health expenditure was significantly higher in the SGLT2 inhibitor cohort versus DPP4 inhibitor cohort ($17,325 versus $15,702; P value <0.0001). After adjusting for socio-economic factors, overall health expenditure (β = −0.3516; P = 0.0038) was significantly lower in DPP4 inhibitor cohort compared to SGLT2 inhibitor.
Conclusion
SGLT2 inhibitors were associated with significantly higher overall and prescription expenditures compared to DPP4 inhibitors during the study period evaluated. Future studies need to utilize administrative claims data to assess current comparativeness effectiveness trends.

Abstract
PURPOSE Data about body compositional changes throughout the course of type 2 diabetes (T2D) are limited and inconsistent. We investigated the roles of the disease duration and glycemic control in T2D-associated changes of body composition and the components of metabolic syndrome (MetS). PATIENTS AND METHODS A total of 25 non-diabetic controls and 92 individuals aged 20-60 years with T2D were included in a case-control study conducted at King Faisal Specialist Hospital, Saudi Arabia. Based on disease duration (newly diagnosed: within the first year and long duration: ≥5 years) and glycemic control (glycated hemoglobin [HbA1C] level ≤7%), the patients were divided into the following groups: newly diagnosed and controlled (N&C, n=25), newly diagnosed and uncontrolled (N&U, n=17), old and controlled (O&C, n=25), and old and uncontrolled (O&U, n=25). Blood samples were collected to assess fasting blood glucose level, HbA1C level, and lipid profile. Anthropometric data were evaluated, and body composition was assessed using a bio-impedancemetry analyzer. Nonparametric tests and multivariable logistic regression analyses were performed. RESULTS Compared to the control group, the fat mass (FM) was significantly higher in all groups; furthermore, the fat mass/fat-free mass (FM/FFM) ratio was significantly higher in the N&C. The N&U and O&U groups showed significantly higher percentages of all components of MetS. Among all selected independent factors, only age increased the likelihood of MetS diagnosis by 7% (OR: 1.07; 95% CI: 1.004-1.149; P<0.05). Besides, age, gender, adherence to diet regimen, and T2D duration showed lower odds of increased FM/FFM ratio. CONCLUSION This study provided evidence about the impact of T2D on body composition and the other components of MetS. Thus, further characterization of T2D contributes to defining the etiology of the disease to detect and treat poor cardiometabolic health.

Abstract
Type 2 diabetes mellitus is a chronic metabolic disease associated with high cardiovascular (CV) risk. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are the latest class of antidiabetic medication that inhibit the absorption of glucose from the proximal tubule of the kidney and hence cause glycosuria. Four SGLT2i are currently commercially available in many countries: canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin. SGLT2i reduce glycated hemoglobin by 0.5%-1.0% and have shown favorable effects on body weight, blood pressure, lipid profile, arterial stiffness and endothelial function. More importantly, SGLT2i have demonstrated impressive cardioprotective and renoprotective effects. The main mechanisms underlying their cardioprotective effects have been attributed to improvement in cardiac cell metabolism, improvement in ventricular loading conditions, inhibition of the Na+/H+ exchange in the myocardial cells, alteration in adipokines and cytokines production, as well as reduction of cardiac cells necrosis and cardiac fibrosis. The main adverse events of SGLT2i include urinary tract and genital infections, as well as euglycemic diabetic ketoacidosis. Concerns have also been raised about the association of SGLT2i with lower limb amputations, Fournier gangrene, risk of bone fractures, female breast cancer, male bladder cancer, orthostatic hypotension, and acute kidney injury.

Abstract
INTRODUCTION This real-world study compared glycemic effectiveness, treatment durability, and treatment costs with canagliflozin 300 mg versus any dose of glucagon-like peptide-1 (GLP-1) receptor agonists in patients with type 2 diabetes mellitus (T2DM) in the USA. RESEARCH DESIGN AND METHODS A retrospective cohort study using administrative claims and laboratory data (1 April 2012 to 28 February 2017) from the HealthCore Integrated Research Database were used to assess mean HbA1c at 3-month intervals, achievement of HbA1c thresholds (<7.0%, <8.0%, <9.0%), and treatment durability (ie, adherence, discontinuation, switching, treatment failure (ie, exceeding threshold (7.0%, 8.0%, 9.0%), having a prescription for a new antihyperglycemic agent)) in adults with T2DM who initiated canagliflozin 300 mg or any dose of a GLP-1 receptor agonist. Medication costs were calculated for adherent patients. RESULTS There were no significant differences in the primary outcome of HbA1c levels at 3-month intervals (≤12 months) in the canagliflozin 300 mg versus any dose GLP-1 receptor agonist cohort. The likelihood of achieving HbA1c<8.0% was not different (p=0.666), the likelihood of achieving HbA1c<7.0% was lower (p=0.016), and the likelihood of achieving HbA1c<9.0% was higher (p=0.020) in the canagliflozin 300 mg versus any dose GLP-1 receptor agonist cohort. The likelihood of treatment failure after reaching any HbA1c target was not different between cohorts. A higher proportion of patients were adherent to treatment (p<0.0001) and a lower proportion discontinued (p<0.0001) or switched medication (p=0.023) in the canagliflozin 300 mg versus any dose GLP-1 receptor agonist cohort. Over 1 year, medication costs were $1421 (p<0.001) lower with canagliflozin 300 mg than any dose of GLP-1 receptor agonists. CONCLUSIONS This real-world, US-based study found that initiation of canagliflozin 300 mg versus any dose of a GLP-1 receptor agonist in patients with T2DM was not associated with significant differences in the primary outcome of HbA1c levels at 3-month intervals for up to 12 months after index, but showed better adherence, less discontinuation, and lower drug acquisition costs compared with initiation of any dose of a GLP-1 receptor agonist.

BACKGROUND SGLT-2 (sodium-glucose cotransporter-2) inhibitors are a novel class of oral hypoglycemic agents for the management of type 2 diabetes mellitus (T2DM). Herein, we aimed to assess the long-term effectiveness and safety of SGLT-2 inhibitors in a Southern Italy population of subjects affected by T2DM. PATIENTS AND METHODS 408 diabetic patients treated with one of the three SGLT-2 inhibitors currently available in Italy (dapagliflozin, empagliflozin, and canagliflozin), either alone or in combination with other antidiabetic drugs, were retrospectively assessed at baseline, during, and after 18 months of continuous therapy. RESULTS Treatment with SGLT-2 inhibitors resulted in a median decrease in HbA1c of 0.9%, with a percentage of decrement of 12 in relation to the baseline value, followed by a significant reduction (P < 0.001) in fasting plasma glucose. Variations in HbA1c occurred independently of the baseline clinical or biochemical characteristics. In addition, treatment with SGLT-2 inhibitors reduced body weight (P < 0.008) and decreased diastolic blood pressure (P = 0.004). With regard to safety outcomes, 66 patients out of 91 stopped SGLT-2 inhibitors during follow-up because of chronic or recurring genital infections, while the rest experienced other adverse events, such as urinary tract infections, polyuria, nausea, hypotension, dizziness, acute coronary event, worsening of glycemic control status, and rapid deterioration of renal function. CONCLUSION In our patients' population, the glycometabolic effects of SGLT-2 inhibitors were durable and comparable to those observed in multicenter randomized controlled trials. This notwithstanding safety concerns must be raised regarding the frequent occurrence of genitourinary infections and the risk of a rapid decline of renal function in patients with evidence of volume depletion and/or receiving other medications which can adversely affect kidney function.
