Glucagon-Like Peptide-1 Receptor Agonists and Major Adverse Cardiovascular Events in Patients With and Without Diabetes: A Meta-Analysis of Randomized-Controlled Trials.

INTRODUCTION: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shown encouraging results regarding cardiovascular outcomes mainly in patients with diabetes. In the present study, we compared the efficacy of GLP-1 RAs in cardiovascular events between patients with and without diabetes. METHODS: After finding eligible studies assessing the impact of GLP-1 RAs on cardiovascular events in patients with and without diabetes using a systematic search, we performed a meta-analysis on randomized-controlled trials (RCTs) comparing cardiovascular outcomes between patients taking GLP-1 RAs and placebo stratified by the presence or absence of diabetes. Relative risk (RR) and its 95% confidence interval (CI) were set as the reporting effect size using the random-effects model. RESULTS: A total of 24 RCTs (50 033 with GLP-1 RAs and 44 514 with placebo) were included. Patients on GLP-1 RAs had lower risk of major adverse cardiovascular events (MACE) (RR 0.87, 95% CI 0.82-0.93), cardiovascular death (RR 0.88, 95% CI 0.82-0.94), myocardial infarction (MI) (RR 0.87, 95% CI 0.77-0.97), stroke (RR 0.86, 95% CI 0.80-0.92), and hospitalization for heart failure (RR 0.90, 95% CI 0.83-0.98). Both subgroups were shown to be effective in terms of MACE and mortality. Nondiabetic patients had decreased risk of hospitalization for heart failure and MI, whereas the diabetic subgroup had marginally nonsignificant efficacy. CONCLUSION: The findings of this meta-analysis indicated that patients who are overweight/obese but do not have diabetes have a comparable reduction in the risk of adverse cardiovascular events as those with diabetes. These results need to be confirmed further by large-scale randomized trials in the future.

An update on the safety of lanreotide autogel for the treatment of patients with neuroendocrine tumors.

INTRODUCTION: Neuroendocrine neoplasms (NENs) are a rare group of tumors originating from neuroendocrine cells in various organs. They include neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs), which differ in biological behavior and prognosis. NETs are usually well-differentiated and slow-growing, while NECs are poorly differentiated and more aggressive. Management of NETs often involves somatostatin analogs like octreotide and lanreotide to control tumor growth and alleviate symptoms, especially in well-differentiated NETs. Lanreotide is used to control tumor growth, and both lanreotide and octreotide alleviate symptoms. Treatment approaches may vary depending on the specific type and grade of the neuroendocrine neoplasm. AREAS COVERED: This review provides an update on the safety of lanreotide autogel in treating patients with NETs, through a comprehensive review of clinical trials, post-marketing surveillance, real-world evidence, and its safety profile. Specific adverse events, side effects, and potential risks associated with lanreotide autogel are discussed, along with risk mitigation strategies and recommendations for patient monitoring. EXPERT OPINION: The findings highlight the overall safety of lanreotide autogel in managing NETs, focusing on its efficacy in controlling hormone secretion, tumor progression, and symptom management. New safety concerns and precautions are also addressed to help healthcare providers make informed decisions when prescribing lanreotide autogel.

Revolutionizing diabetes care: unveiling tirzepatide's potential in glycemic control and beyond.

INTRODUCTION: Diabetes is a global public health challenge with rising prevalence. This review explores current diabetes understanding, diagnostic and management guidelines, economic impact, and lifestyle modifications as the primary approach. AREAS COVERED: Focusing on pharmacological interventions, we discuss the roles of GLP-1 agonists and GLP/GIP agonists in diabetes management and cardiovascular risk reduction. Tirzepatide, a novel medication, is highlighted for its unique mechanism of action. Clinical trials demonstrate its effectiveness in glucose control, weight reduction, and its potential impact on diabetes, obesity, NASH, and cardiovascular risks. EXPERT OPINION: Tirzepatide shows promise in diabetes treatment, offering glucose control and weight loss. It also holds potential for addressing comorbidities. However, cautious use is vital due to potential adverse effects and contraindications, including hypersensitivity reactions, pregnancy, and breastfeeding precautions. This review underscores tirzepatide as a valuable addition to diabetes therapies, with evolving prospects for enhanced patient outcomes as research advances.

Cardiovascular Outcomes of Hypogonadal Men Receiving Testosterone Replacement Therapy: A Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: To investigate the impact of testosterone replacement therapy (TRT) on cardiovascular outcomes in hypogonadal men. METHODS: A meta-analysis of 26 randomized controlled trials involving 10 941 participants was conducted. Various clinical outcomes, including all-cause mortality, cardiovascular-related mortality, myocardial infarction, stroke, congestive heart failure, atrial fibrillation, pulmonary embolism, and venous thrombosis, were assessed. RESULTS: No statistically significant differences were observed between the TRT group and the control group in terms of these clinical outcomes. Sensitivity analysis and publication bias assessment supported the robustness of the findings. Meta-regression analysis found no significant associations between clinical outcomes and potential covariates, including age, diabetes, hypertension, dyslipidemia, and smoking. DISCUSSION: Previous research on TRT and cardiovascular events, with comparisons to studies like the Testosterone Trials and the studies conducted by Vigen et al, Finkle et al, Layton et al, and Wallis et al, is provided. The significance of the systematic review and meta-analysis approach is emphasized, particularly its exclusive focus on hypogonadal patients. CONCLUSION: This study offers reassurance that TRT does not increase mortality risk or worsen cardiovascular outcomes in hypogonadal men. However, further research, especially long-term studies involving diverse populations, is essential to strengthen the evidence base and broaden the applicability of these findings.

Sex-Specific Differences in Clinical Outcomes in Patients With Coronary Bifurcation Lesions.

Coronary bifurcation lesions are frequent challenging findings during percutaneous coronary intervention (PCI). Contemporary evidence has explored the potential sex-specific differences in patients undergoing PCI. In the present meta-analysis, we compared clinical outcomes of patients undergoing bifurcation PCI between women and men. Using the random-effects method, we compared the clinical outcomes of patients with a coronary bifurcation lesion following PCI between women and men. The results were reported using relative risk (RR) and 95% confidence interval (CI). Baseline comorbidities and mean age were compared between the 2 studied groups. Four observational studies comprising 30,684 patients (8898 women and 21,786 men) were included in the meta-analysis. Women were significantly older than men with a relatively higher prevalence of baseline comorbidities. After using adjusted data from 2 out of 4 available studies, performing PCI for bifurcation lesions in women was not associated with an increased risk of mortality (RR 1.33, 95% CI, 0.78-2.29), myocardial infarction (RR 1.22, 95% CI, 0.41-3.61), target lesion revascularization (RR 1.06, 95% CI, 0.40-2.81), stent thrombosis (RR 0.99, 95% CI, 0.09-10.52), and stroke (RR 1.19, 95% CI, 0.64-2.22). Women were at higher risk of major bleeding compared to male counterparts (RR 2.23, 95% CI, 1.73-2.89). The present study showed no difference in the risk of adverse clinical outcomes except the risk of bleeding between genders with coronary bifurcation lesions. Future studies with adjustment of age and baseline comorbidities are needed to confirm these findings.
