RESUMEN

Background: In 2023, the Obesity Medicine Association (OMA) published "Compounded peptides: An Obesity Medicine Association Position Statement." Since this publication, the use of compounded peptides for the treatment of obesity has continued to evolve, leading to additional confusion and questions from obesity medicine clinicians and their patients. Methods: This frequently asked questions (FAQ) document and "Call for Action" commentary is based upon the existing evidence and practical clinical experiences of the authors. Results: This FAQ is intended to provide insights beyond the original 2023 OMA Position Statement regarding the use of "compounded peptides" for treating obesity. Three obstacles impair patient access to highly effective peptide anti-obesity medications: insufficient production especially during times of high demand, high costs, and lack of clarity surrounding the role of compounded peptides. Solutions to enhance patient access to these medications lie within the existing legal and regulatory framework and Food and Drug Administration policies. Implementing these solutions necessitates dispelling misinformation and providing clear guidance on the appropriate prescribing and administration of compounded peptides, particularly during times of acknowledged shortage. Conclusion: Among stakeholders with aligned priorities, challenges can often be overcome by collaboration and communication. Towards the goal of providing patient-centered care, the OMA calls on applicable stakeholders (e.g., pharmaceutical companies, compounding pharmacy organizations, health insurance companies, and the Food and Drug Administration) to work collaboratively to achieve a consensus that improves patient access to safe anti-obesity medications. The purpose of this "Call to Action" is to ask stakeholders to provide clinicians and their patients clarity regarding the role of compounded peptide anti-obesity medications during times of FDA-acknowledged shortages. Finally, this FAQ review provides clinicians with a simple and practical checklist respective to the potential use of compounded peptides.

RESUMEN

PURPOSE OF REVIEW: Cardiovascular disease (CVD) is the leading cause of death globally and is closely associated with obesity and type 2 diabetes mellitus (T2DM). This review examines the interplay between obesity, T2DM, and CVD, highlighting the increasing prevalence and economic burden of these conditions. RECENT FINDINGS: Pharmacologic therapies, particularly glucagon-like peptide-1 receptor agonists, show promise in substantial weight loss and subsequent reduction of adverse cardiovascular events in obese individuals with and without diabetes. Obesity significantly contributes to the development of insulin resistance and T2DM, further escalating CVD risk. The common co-occurrence of these three conditions may involve several other pathophysiological mechanisms, such as chronic inflammation, increased visceral adiposity, and endothelial dysfunction. Until recently, lifestyle modifications and bariatric surgery had been the primary methods for weight loss and mitigating obesity-associated cardiovascular risk. Newer pharmacological options have led to a paradigm shift in our approach to obesity management as they provide substantial benefits in weight loss, glycemic control, and cardiovascular risk reduction.

RESUMEN

Recently, a health-care database study showed that persons with type 2 diabetes taking GLP-1 receptor agonists (GLP-1 RA) had a significantly lower risk of 10 out of 13 obesity-related cancers than patients taking insulin (Wang L, et al. JAMA Netw Open. 2024 7: e2421305). For some cancers, hazard ratios <0.5 were reported. This is reminiscent of studies published >10 years ago showing that people with type 2 diabetes taking metformin had a lower risk of many types of cancer than those not taking metformin. In some studies, also risk reductions of >50 % were reported. The strong effects observed in the metformin studies were explained by time-related biases, in particular, immortal time bias. In the current GLP-1 RA study, it was striking that the curves for the cumulative incidence of several cancers in GLP-1 RA and insulin users diverged immediately after therapy onset. This indicates that there is most likely a time-related bias: insulin is given at much later stages of type 2 diabetes than GLP-1 RA. The current study suggests that one should be sceptical about database results when spectacular risk reductions are reported. Time-related bias should always be considered as an alternative explanation.

RESUMEN

Glucagon-like peptide-1 (GLP-1) is a gastrointestinal regulatory hormone that stimulates insulin release from the pancreas. While GLP-1 receptor agonists (GLP-1 RAs) have traditionally been utilized to address insulin resistance, their potential application in treating polycystic ovary syndrome (PCOS) has recently garnered attention. This study aimed to investigate the therapeutic efficacy of GLP-1 RAs use for weight loss in women diagnosed with PCOS. We conducted a scoping review following the Joanna Briggs Institute (JBI) methodology and adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our investigation delved into the clinical effects experienced by women of diverse racial and ethnic backgrounds with PCOS who were prescribed GLP-1 RAs for weight loss. Peer-reviewed articles from Ovid Medline, Web of Science, CINAHL, Cochrane CENTRAL, SCOPUS, and ClinicalTrials.gov spanning from 2012 to 2023 were scrutinized. After eliminating duplicates, 811 articles were identified, and ultimately, eight met the eligibility criteria for inclusion. All studies were published in English and exhibited wide geographic diversity. The included studies uniformly reported reductions in weight and body mass index (BMI) among patients who were prescribed GLP-1 RAs, specifically liraglutide or exenatide. Additionally, evidence pointed towards improvements in anthropometric parameters (MF1) (including total body weight, BMI, reduction in waist circumference, and total fat percentage), glucose homeostasis, cardiovascular inflammatory markers (midregional pro-atrial natriuretic peptide (MR-proANP) and mid-regional pro-adrenomedullin (MR-proADM)), rates of pregnancy, and menstrual regulation. However, findings regarding the impact of GLP-1 RAs on lipid profiles were inconsistent. Although some short-term adverse effects were noted, long-term effects of GLP-1 RAs use remain undetermined. GLP-1 RA use demonstrated promising clinical outcomes for women with PCOS, including reduced BMI, improved metabolic parameters, menstrual regularity, and increased rates of natural pregnancy. While the current evidence is encouraging, further research is warranted to elucidate both short- and long-term adverse effects of GLP-1 RA therapy for PCOS.

RESUMEN

Cardiovascular risks and complications remain elevated in patients with type 2 diabetes even after appropriate control of contributing factors like glycemic control, hypertension, and lipid profile. More efficient methods are needed to address this issue in type 2 diabetics. Newer drugs like glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shown a cardioprotective effect in addition to glycemic control. This systematic review aims to study the latest literature findings on the cardiovascular effects of GLP-1 RAs in patients with type 2 diabetes. We used PubMed, Google Scholar, Science Direct, and Biomed Central databases for our data collection. Our review adheres to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The outcomes evaluated in the review include major adverse cardiovascular events (MACE), heart failure, stroke, all-cause mortality, and effects on cardiovascular risk factors. After careful inspection and quality check, we included 14 articles in the systematic review. GLP-1 RAs were associated with a significant reduction in cardiovascular mortality, all-cause mortality, nonfatal myocardial infarction (MI), and nonfatal stroke, especially in patients with existing cardiovascular risk factors. However, more evidence is required to determine if these benefits extend to those without such risk factors. Limited data suggest that GLP-1 RAs might have a protective effect on arrhythmias, but this area needs further investigation. Despite their potential, several barriers hinder the widespread use of GLP-1 RAs. In conclusion, GLP-1 RAs significantly reduce cardiovascular mortality, all-cause mortality, nonfatal MI, and stroke, with minor effects on hospitalization due to heart failure. Benefits are greater in patients with cardiovascular risk factors. A comprehensive, multilevel approach to policy development and implementation is necessary to optimize the use of these medications in eligible populations.

RESUMEN

BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), particularly semaglutide, have become the leading anti-obesity drugs for adults, and a similar trend may follow in adolescents with its recent approval for this age group. However, there is a lack of comparative analysis on the weight loss effects and safety of GLP-1 RAs in obese or overweight pediatric and adolescent populations, especially those who are non-diabetic. This systematic review and meta-analysis aim to provide current evidence on the efficacy and safety of GLP-1 RAs as an anti-obesity treatment in obese or overweight non-diabetic pediatric and adolescent populations. METHOD:  We searched electronic databases from inception until January 2024 for randomized controlled trials (RCTs) that analyzed the weight loss effect of GLP-1 receptor agonists in adolescents with obesity or overweight without diabetes mellitus. Search results were screened, and eligible studies were included to perform a systematic review and meta-analysis using the Review Manager (RevMan) computer program Version 5.4.1 (The Cochrane Collaboration, 2020) with a random-effects model. The primary efficacy outcomes were changes in body weight, BMI, and BMI Z-score, while the secondary outcomes were the incidence of gastrointestinal adverse events, treatment discontinuation rate due to adverse events, and incidence of serious adverse events. The mean difference, odds ratio, and 95% confidence interval (CI) were used to present the meta-analysis results. Publication bias was visualized using a funnel plot. The quality of the studies was analyzed using Cochrane's Risk of Bias tool (RoB2). RESULTS: A total of seven RCTs with 576 adolescent participants were included in the analysis. GLP-1 RAs significantly achieved greater weight loss than placebo, with a mean difference of -4.98 kg (-8.49, -1.46), I² = 99%, p = 0.006. Subgroup analysis showed that semaglutide had the most pronounced anti-obesity effect (mean difference of -17.70 kg (-18.89, -16.51), p < 0.00001), compared to liraglutide (mean difference of -2.26 kg (-5.17, 0.65), I² = 99%, p = 0.13) and exenatide (mean difference of -3.17 kg (-4.45, -1.90), I² = 0%, p < 0.0001). Similar results were obtained for other efficacy parameters such as BMI and BMI z-score. However, GLP-1 RA was associated with more gastrointestinal adverse events (such as nausea and vomiting) than placebo (3.06 (2.12, 4.42), I² = 0%, p < 0.00001), with incidence comparable among all GLP-1 RAs in the subgroup analysis. The overall risk of bias among included studies was either of 'some concern' or 'high risk.' CONCLUSIONS: Our meta-analysis demonstrated that GLP-1 RAs had a superior anti-obesity effect compared to placebo or lifestyle modification in obese or overweight non-diabetic adolescents, particularly semaglutide, which had a more pronounced anti-obesity effect than liraglutide and exenatide, with tolerable gastrointestinal adverse effects.

RESUMEN

This review explores the mechanisms and ramifications of weight loss achieved through lifestyle modifications, medical treatments, and bariatric surgery on testosterone levels and sexual health. Obesity significantly affects the hypothalamic-pituitary-gonadal axis in men, leading to diminished libido and erectile dysfunction. Here, we delve into the physiological disruptions caused by this imbalance and the intricate interplay of hormonal factors contributing to the dysregulation associated with obesity to comprehensively grasp the consequences of weight loss via diverse mechanisms. Lifestyle modifications involving dietary adjustments and regular exercise represent a widely employed and efficacious means of weight loss. While adherence demands discipline, our review scrutinizes various studies specifically investigating the impact of weight loss, attained through lifestyle modifications, on serum hormone levels and sexual function. Notably, several randomized controlled trials within the existing body of literature corroborate the enhancement of testosterone levels and sexual function consequent to weight loss through lifestyle modifications. The realm of medical management in addressing obesity is growing, notably propelled by the popularity of pharmacotherapy. Despite its prevalence, the current literature exploring the effects of weight loss medications on men remains insufficient. Nonetheless, we examine available studies on the medical management of obesity and its implications for sexual health, emphasizing pivotal avenues requiring further investigation. Bariatric surgery stands as an effective approach for individuals seeking substantial weight loss. Our review assesses existing literature that evaluates the impact of various surgical techniques on serum hormone levels, sexual function, and semen parameters. Despite certain limitations, the available body of evidence suggests enhancements in hormone levels and sexual function post-surgery, with semen parameters generally exhibiting minimal changes. This review critically evaluates the landscape of weight loss and its correlation with sexual function, while highlighting crucial areas necessitating future research endeavors.

RESUMEN

BACKGROUND: Increasing evidence suggests that GLP-1 receptor agonists (GLP-1RA) have a potential use in addiction treatment. Few studies have assessed the impact of GLP-1RA on substance use disorder (SUD), particularly in humans. The study aimed to do systematic review of clinical trials to assess GLP-1RA's effect on reducing SUD in patients. METHODS: The scientific literature was reviewed using the MEDLINE, Scopus and Cochrane Library databases, following PRISMA guidelines. Studies including patients with a diagnosis of SU who were treated with GLP-1RA were selected. The primary outcome was GLP-1RA's therapeutic effect on SUD, and the secondary outcomes were therapeutic effects of GLP-1RA on weight, BMI and HbA1c. RESULTS: 1218 studies were retrieved, resulting in 507 papers after title and abstract screening. Following full-text review, only 5 articles met inclusion criteria. We incorporated a total of 630 participants utilizing Exenatide (n=3) and Dulaglutide (n=2) as GLP-1RAs. Therapeutic effect of GLP-1RA on SUD was assessed in 5 studies, with 3 demonstrating a significant decrease in SUD (alcohol and nicotine). GLP-1RA's impact on body weight, BMI, and HbA1c, was reported in 3 studies. These revealed a notable reduction in these parameters among the GLP-1RA treated group. CONCLUSION: This review will give an overview of current new findings in human studies; we suggest that the effects of GLP-1RA in SUD is a possible new option of therapy in addiction medicine.

RESUMEN

Background: Dipeptidyl peptidase-4 inhibitors (DPP-4is) are the most widely used oral hypoglycemic drugs in Japan. However, once-daily oral semaglutide has been reported to reduce glycated hemoglobin (HbA1c) and body weight (BW) without causing significant hypoglycemia. Here, we aimed to evaluate the efficacy and safety of switching from a DPP-4i to oral semaglutide in Japanese patients with type 2 diabetes (T2D). Methods: We performed a single-center retrospective study of the changes in HbA1c and BW in 68 patients with T2D who were switched from a DPP-4i and took oral semaglutide for ≥ 6 months, without changes in any other oral hypoglycemic agent. Results: Mean HbA1c decreased from 7.8 to 7.0% (p < 0.001) and BW decreased from 74.2 to 71.2 kg (p < 0.001) over 6 months. The decrease in HbA1c was more pronounced in participants with high baseline HbA1c (r = - 0.542, p < 0.001). There was also a trend (r = 0.236, p = 0.052) toward a decrease in BW in individuals with shorter disease duration. There were reductions in either HbA1c or BW in 65 participants (95.6%). In addition, the larger the decrease in HbA1c was, the greater was the decrease in BW (r = 0.480, p < 0.001). Eighteen participants (20.1%) discontinued the drug within 6 months, of whom 10 (11.6% of the total) did so because of suspected adverse effects and the discontinuation rate was the highest in older, non-obese patients. Conclusions: Switching from a DPP-4i to oral semaglutide may be useful for Japanese patients with T2D who have inadequate glycemic or BW control. However, its utility may be limited by gastrointestinal adverse effects in certain patients.

RESUMEN

Given the substantial burden of chronic kidney disease associated with type 2 diabetes, an aggressive approach to treatment is required. Despite the benefits of guideline-directed therapy, there remains a high residual risk of continuing progression of chronic kidney disease and of cardiovascular events. Historically, a linear approach to pharmacologic management of chronic kidney disease has been used, in which drugs are added, then adjusted, optimized, or stopped in a stepwise manner based on their efficacy, toxicity, effects on a patient's quality of life, and cost. However, there are disadvantages to this approach, which may result in missing a window of opportunity to slow chronic kidney disease progression. Instead, a pillar approach has been proposed to enable earlier treatment that simultaneously targets multiple pathways involved in disease progression. Combination therapy in patients with chronic kidney disease associated with type 2 diabetes is being investigated in several clinical trials. In this article, we discuss current treatment options for patients with chronic kidney disease associated with type 2 diabetes and provide a rationale for tailored combinations of therapies with complementary mechanisms of action to optimize therapy using a pillar-based treatment strategy.

RESUMEN

Objective: This study aims to investigate the effects of semaglutide on gut microbiota, cognitive function, and inflammation in obese mice. Method: Twenty-four C57BL/6J male mice were randomly assigned to three groups: a normal-chow diet group (NCD, n = 8), high-fat diet group (HFD, n = 8), and HFD+semaglutide group (Sema, n = 8). The mice were fed a HFD to establish an animal model of obesity and then administered with semaglutide or saline for 12 weeks. Cognitive function was assessed using the Morris water maze test. Serum pro-inflammatory cytokines were measured. 16S rRNA gene sequencing technology was used to explore gut microbiota characteristics in obese mice. Result: Obese mice showed significant cognitive impairment and inflammation. Semaglutide improved cognitive function and attenuated inflammation induced by a HFD diet. The abundance of gut microbiota was significantly changed in the HFD group, including decreased Akkermansia, Muribaculaceae, Coriobacteriaceae_UCG_002, Clostridia_UCG_014 and increased Romboutsia, Dubosiella, Enterorhabdus. Whereas semaglutide could dramatically reverse the relative abundance of these gut microbiota. Correlation analysis suggested that cognitive function was positively correlated with Muribaculaceae and Clostridia_UCG_014, and negatively associated with Romboutsia and Dubosiella. Romboutsia was positively correlated with TNFα, IL-6 and IL-1ß. While Clostridia_UCG_014 was negatively related to TNFα, IL-6 and IL-1ß. Conclusions: For the first time semaglutide displayed different regulatory effects on HFD-induced gut microbiota dysbiosis. Semaglutide could regulate the structure and composition of gut microbiota associated with cognitive function and inflammation. Thus, affecting gut microbiota might be a potential mechanism of semaglutide in attenuating cognitive function and inflammation.

RESUMEN

This narrative review article explores the complex interplay between obesity, osteoarthritis, and their associated inflammatory cascades, offering a deeper understanding of the underlying of mechanisms of inflammation and potential therapeutic interventions targeting both diseases. Through examination of the shared inflammatory pathway of obesity and osteoarthritis, our objective is to directly elucidate the relationship between these two conditions, highlighting the promising role of glucagon-like peptide-1 agonists in modulating inflammation and its therapeutic implications for patients with obesity and osteoarthritis.

RESUMEN

Although, in randomized clinical trials, once-weekly subcutaneous semaglutide (OW s.c.) has demonstrated superior efficacy in comparison with placebo and active controls in terms of glycemic control and body weight reduction in patients with type 2 diabetes mellitus (T2DM), these results need to be confirmed in a real-world (RW) setting. An RW ambispective study (6 months retrospective and 6 months prospective) was conducted in 10 tertiary hospitals in Spain. We evaluated changes in HbA1c and body weight in patients with T2DM treated with semaglutide OW s.c. Additionally, we analyzed different subgroups of patients treated with semaglutide OW s.c. as an add-on to glucose-lowering therapy. A total of 752 patients with a mean age of 60.2 years, a mean HbA1c level of 8.5%, a mean body weight of 101.6 kg, and a mean T2DM duration of 10 years were included. At 12 months, compared with baseline, there was a mean difference of -2.1% in HbA1c levels (p < 0.001) and a mean difference of 9.2 kg in body weight (p < 0.001). Moreover, there were statistically significant differences (p < 0.001) between baseline and month 12 in both HbA1c and body weight in the four subgroups receiving semaglutide OW s.c. as an add-on to glucose-lowering therapy. Semaglutide OW s.c. was well tolerated, with gastrointestinal disorders being the most commonly reported side effects. In this RW study, 12 months of treatment with semaglutide OW s.c. in patients with T2DM was associated with significant and clinically relevant improvements in glycemic control and weight loss, regardless of the glucose-lowering therapy received, and the overall safety profile was positive.

RESUMEN

PURPOSE: The evaluation of the effect of dulaglutide on glycated hemoglobin (HbA1c) and non-invasive indices of hepatic steatosis among different genotypes of the PNPLA3 I148M (rs738409) and CETP Taq1B (rs708272) polymorphisms in patients with type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease (NAFLD). METHODS: Relevant data from patients with inadequately controlled T2DM, also displaying NAFLD, administered 1.5 mg dulaglutide weekly for 6 months were retrospectively retrieved. The non-invasive indices, fatty liver index (FLI) and hepatic steatosis index (HSI), were calculated. Genotyping for rs738409 and rs708272 were performed with polymerase chain reaction. RESULTS: Data from 80 patients (39 females), aged 64.4 ± 9.5 years and displaying a baseline BMI of 34.5 ± 5.8 kg/m2, were retrieved at baseline and after 6 months (endpoint) of dulaglutide treatment. Glycated hemoglobin (HbA1c; -0.72 ± 1.10%; p < 0.001), FLI (-5.8 ± 9.8; p < 0.001) and HSI (-1.18 ± 3.51; p = 0.004) significantly decreased after treatment. Lipid profile and liver function tests also improved after treatment. Overall, homozygotes for the reference rs738409 allele (CC) displayed a 2.4-fold decrease (p = 0.002) and heterozygotes (CG) an 1.6-fold decrease (p = 0.013) compared to GG homozygotes after treatment, but the effect was largely limited to female patients. No similar effect was observed in FLI, HSI and other relevant parameters. No association was observed between rs708272 and any of the parameters studied. CONCLUSIONS: rs738409, but not rs708272, was associated with the effect of dulaglutide on HbA1c, but not on presumed hepatic steatosis or other relevant parameters. Sex-specific effects were also noticed.

RESUMEN

Glucagon-like peptide-1 receptor agonist (GLP-1RA) medications have been shown to be effective in achieving optimal glucose control and reducing all-cause death, cardiovascular death, nonfatal myocardial infarction, hospitalization for heart failure, and end-stage kidney disease in individuals with type 1 (T1D) and type 2 diabetes (T2D). However, use of these medications has been associated with increased hypoglycaemia risk in patients treated with concomitant antihyperglycaemic medications. The risk is particularly high in patients with T1D due to their loss of glucagon counter-regulatory response. This article reviews the effect of GLP-1RA formulations on the development of hypoglycaemia in individuals with T1D and T2D treated with insulin therapy, discusses the benefits of continuous glucose monitoring with GLP-1RA treatment, and presents strategies for safely initiating GLP-1RA therapy in these individuals.

RESUMEN

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors (SGLT2I) have been suggested to reduce new-onset cancer amongst type-2 diabetes mellitus (T2DM) patients. This study aims to compare the risks of prostate cancer between SGLT2I and dipeptidyl peptidase-4 inhibitors (DPP4I) amongst T2DM patients. DESIGN, SETTING AND PARTICIPANTS: This was a retrospective population-based cohort study of prospectively recorded data on male patients with T2DM who were prescribed either SGLT2I or DPP4I between 1st January 2015 and 31st December 2020 from Hong Kong. METHODS: The primary outcome was new-onset prostate cancer. The secondary outcomes included cancer-related mortality and all-cause mortality. Propensity score matching (1:1 ratio) using the nearest neighbor search was performed and multivariable Cox regression was applied. A three-arm analysis including the glucagon-like peptide-1 receptor agonist (GLP1a) cohort was conducted. RESULTS: This study included 42129 male T2DM patients (median age: 61.0 years old [SD: 12.2]; SGLT2I: n = 17,120; DPP4I: n = 25,009). In the propensity score matched cohort, the number of prostate cancers was significantly lower in SGLT2I users (n = 60) than in DPP4I (n = 102). Over a follow-up duration of 5.61 years, SGLT2I was associated with lower prostate cancer risks (HR: 0.45; 95% CI: 0.30-0.70) than DPP4I after adjustments. The subgroup analyses showed that the interactions between SGLT2I and age, hypertension, heart failure, and GLP-1a were not statistically significant. The result remained consistent in the sensitivity analysis. CONCLUSION: The study demonstrated SGLT2I was associated with lower risks of new-onset prostate cancer after propensity score matching and adjustments compared to DPP4I amongst T2DM patients.

RESUMEN

Owing to their potent glucose-lowering efficacy and substantial weight loss effects, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are now considered part of the frontline therapeutic options to treat both type 2 diabetes mellitus and nondiabetic overweight/obesity. Stemming from successful demonstration of their cardiometabolic modulation and reduction of major adverse cardiovascular events in clinical outcome trials, GLP-1 RAs have since been validated as agents with compelling cardiovascular protective properties. Studies spanning from the bench to preclinical and large-scale randomised controlled trials have consistently corroborated the cardiovascular benefits of this pharmacological class. Most notably, there is converging evidence that they exert favourable effects on atherosclerotic ischaemic endpoints, with preclinical data indicating that they may do so by directly modifying the burden and composition of atherosclerotic plaques. This narrative review examines the underlying pharmacology and clinical evidence behind the cardiovascular benefits of GLP-1 RAs, with particular focus on atherosclerotic cardiovascular disease. It also delves into the mechanisms that underpin their putative plaque-modifying actions, addresses existing knowledge gaps and therapeutic challenges and looks to future developments in the field, including the use of combination incretin agents for diabetes and weight loss management.

RESUMEN

AIM: To evaluate the potential association between suicidality and glucagon-like peptide-1 receptor agonists (GLP-1RAs), as well as other medications used for obesity and diabetes, using comprehensive global data. MATERIALS AND METHODS: This study utilized the World Health Organization's pharmacovigilance database, encompassing adverse drug reaction reports from 1967 to 2023, from 170 countries (total reports, N = 131 255 418). We present the reported odds ratios (RORs) with 95% confidence intervals (CIs) and information component (IC) with IC025 regarding the association between GLP-1RA use and suicidality. RESULTS: Although reports of GLP-1RA-associated suicidality increased gradually from 2005 to 2023 (n = 332), no evidence of an association was observed (ROR 0.15 [95% CI 0.13 to 0.16]; IC -2.77 [IC025 -2.95]). The lack of evidence of an association persisted regardless of whether GLP-1RAs were used for diabetes treatment (ROR 0.13 [95% CI 0.11 to 0.14]; IC -2.95 [IC025 -3.14]) or obesity treatment (ROR 0.44 [95% CI 0.34 to 0.58]; IC -1.16 [IC025 -1.62]). However, an association was found between suicidality and other diabetes medications excluding GLP-1RAs (ROR 1.13 [95% CI 1.10 to 1.15]; IC 0.17 [IC025 0.13]). Similarly, the potential association with suicidality was observed in medications used to treat obesity excluding GLP-1RAs (ROR 1.08 [95% CI 1.01 to 1.14]; IC 0.10 [IC025 0.01]). CONCLUSIONS: The suspected association between GLP-1RA use and suicidality, as raised by the European Medicines Agency, was not found in our global analysis. This indicates that the sporadic reports of GLP-1RA-associated suicidality are likely influenced by factors such as comorbidities present in the GLP-1RA user population.

RESUMEN

The concept of quadruple therapy as a "one-size-fit-all" approach is effective among all eligible patients with heart failure with reduced ejection fraction, with consistent and significant clinical benefits including reduced mortality across various subgroups. However, with exception of sodium-glucose cotransporter 2 inhibitors, the consistency of benefit with therapies does not extend to patients with heart failure with preserved ejection fraction. The clinical benefits of other promising medical therapies, such as angiotensin receptor-neprilysin inhibitors, mineralocorticoid receptor antagonists, and glucagon-like peptide-1 receptor agonists, have been demonstrated only in certain phenotypes of the highly heterogenous heart failure with preserved ejection fraction population. This variability can confuse frontline practicing cardiologists, potentially leading to the under-implementation of these medications. Therefore, we propose a simple approach: "targeted" combination therapy. This strategy aims to optimize evidence-based medications in heart failure with preserved ejection fraction by tailoring treatments to specific subgroups within the heart failure with preserved ejection fraction population where significant benefits are most evident.
