Semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, is a widely used drug for the treatment of type 2 diabetes that offers significant cardiovascular benefits.
Results
This review systematically examines the proteomic and metabolomic indicators associated with the cardiovascular effects of semaglutide. A comprehensive literature search was conducted to identify relevant studies. The review utilizes advanced analytical technologies such as mass spectrometry and nuclear magnetic resonance (NMR) to investigate the molecular mechanisms underlying the effects of semaglutide on insulin secretion, weight control, anti-inflammatory activities and lipid metabolism. These “omics” approaches offer critical insights into metabolic changes associated with cardiovascular health. However, challenges remain such as individual variability in expression, the need for comprehensive validation and the integration of these data with clinical parameters. These issues need to be addressed through further research to refine these indicators and increase their clinical utility.
Conclusion
Future integration of proteomic and metabolomic data with artificial intelligence (AI) promises to improve prediction and monitoring of cardiovascular outcomes and may enable more accurate and effective management of cardiovascular health in patients with type 2 diabetes. This review highlights the transformative potential of integrating proteomics, metabolomics and AI to advance cardiovascular medicine and improve patient outcomes.

Background
Sodium-glucose co-transporter-2 inhibitors (SGLT2is) reduce cardiovascular risk in people with diabetes and established cardiovascular disease, but emerging studies in chronic kidney disease (CKD) have inconsistent results. In this systematic review, we evaluate the effects of SGLT2is on cardiovascular mortality in people with CKD as a whole and across subgroups stratified by baseline kidney function and among people at low, moderate, high and very high risk according to KDIGO- CKD classification system.
Methods
Literature search was conducted in PubMed/MEDLINE, Cochrane/CENTRAL, Scopus and Web of Science up to 30 November 2023. We included randomized controlled trials assessing the effect of SGLT2is on cardiovascular mortality in people with CKD. Secondary outcomes included all-cause mortality and major adverse cardiac events (MACE).
Results
Eleven studies (n = 83,203 participants) were included. In people with CKD, treatment with SGLT2is compared to placebo reduced the risk of cardiovascular death by 14% (hazard ratio [HR] .86; 95%CI .79–.94), all-cause death by 15% (HR .85; 95%CI .79–.91) and MACEs by 13% (HR .87; 95%CI .81–.93). A consistent treatment effect was observed across eGFR-subgroups (≥60 mL/min/1.73 m2: HR .82, 95%CI .65–1.02; <60 mL/min/1.73 m2: HR .86, 95%CI .77–.96, p-subgroup difference = .68) and KDIGO risk-categories (low, moderate, high and very high) (p-subgroup difference = .69) for cardiovascular death; reduction in the risk of all-cause death tended to be greater in the highest KDIGO risk categories. A consistent treatment effect on cardiovascular mortality was observed for different SGLT2is agents studied. Sensitivity analysis for cardiovascular mortality endpoint including studies in diabetic people yielded similar results (HR .86; 95%CI .77–.97).
Conclusions
Treatment with SGLT2is led to a significant reduction in the risk of cardiovascular and all-cause mortality in people with different CKD stages. These findings support the use of SGLT2is as an adjunct cardiovascular protective therapy in CKD.

Background
The clinical relevance of cardiac troponin (cTn) elevation in takotsubo syndrome (TTS) remains uncertain. The present study sought to investigate the role of cardiac troponin (cTn) elevations in mortality prediction of patients with Takotsubo syndrome (TTS).
Methods
Patients enrolled in the International Takotsubo (InterTAK) Registry from January 2011 to February 2020 with available data on peak cTn levels were included in the analysis. Peak cTn levels during the index hospitalization were used to define clinically relevant myocardial injury. The threshold at which clinically relevant myocardial injury drives mortality at 1 year was identified using restricted cubic spline analysis.
Results
Out of 2′938 patients, 222 (7.6%) patients died during 1-year follow-up. A more than 28.8-fold increase of cTn above the upper reference limit was identified as threshold for clinically relevant myocardial injury. The presence of clinically relevant myocardial injury was significantly associated with an increased risk of mortality at 5 years (adjusted HR 1.58, 95% CI 1.18–2.12, p =.002). Clinically relevant myocardial injury was related to an increased 5-year mortality risk in patients with apical TTS (adjusted HR 1.57, 95% CI 1.21–2.03, p =.001), in presence of physical stressors (adjusted HR 1.60, 95% CI 1.22–2.11, p =.001), and in absence of emotional stressors (adjusted HR 1.49, 95% CI, 1.17–1.89, p =.001).
Conclusion
This study for the first time determined a troponin threshold for the identification of TTS patients at excess risk of mortality. These findings advance risk stratification in TTS and assist in identifying patients in need for close monitoring and follow-up.

Background
Obesity is a growing epidemic affecting approximately 40% of the adult population in developed countries with major health consequences and comorbidities, including diabetes mellitus and insulin resistance, metabolically associated fatty liver disease, atherosclerotic cardiovascular and cerebrovascular diseases and chronic kidney disease. Pharmacotherapies targeting significant weight reduction may have beneficial effects on such comorbidities, though such therapeutic options are highly limited. In this narrative review, we aim to evaluate current knowledge regarding dual agonist therapies and potential implications for managing fatty kidney and chronic kidney disease.
Results and Conclusion
Glucagon-like peptide-1 agonists and sodium-glucose cotransporter-2 inhibitors are two novel classes of glucose-lowering medications with potential implications and beneficiary effects on renal outcomes, including estimated glomerular filtration rate, albuminuria and chronic kidney disease progression. Recently, dual agonist therapies targeting glucagon-like peptide-1 and glucagon receptors, namely survodutide and cotadutide, have been evaluated in managing metabolically associated fatty liver disease, a well-established example of visceral obesity. Fatty kidney is another novel concept implicated in the pathophysiology of chronic kidney disease among patients with visceral obesity.

Background
4D-CT has garnered attention as complementary imaging for patients with primary hyperparathyroidism (pHPT). Herein we evaluated a diagnostic strategy using [18F]Fluorocholine Positron Emission Tomography/Computed Tomography (PET/CT), followed by 4D-CT integrated into PET/4D-CT after negative/inconclusive PET/CT results in a single-center retrospective cohort of 166 pHPT patients who underwent parathyroidectomy after [18F]Fluorocholine PET/4D-CT.
Methods
PET/CT and 4D-CT images were interpreted by three nuclear medicine physicians and one expert radiologist. Pathological findings were documented, and concordance rates were assessed. PET/CT results were categorized as positive/negative, with positive cases rated on a 3-level certitude scale: low, moderate, high. Inconclusive cases included low/moderate positivity. The added value of PET/4D-CT was assessed for negative/inconclusive cases through joint reading.
Results
PET/CT lesion-based analysis showed almost perfect interobserver concordance (Cohen's kappa >.8). Across the cohort, PET/CT had a sensitivity of 83%, specificity of 97%, PPV of 90% and NPV of 94%. For 4D-CT, these values were sensitivity: 53%, specificity: 84%, PPV: 56% and NPV: 82%. PET/CT was significantly more accurate than 4D-CT. Among 44 patients with negative/inconclusive results, PET/CT had sensitivity: 60%, specificity: 91%, PPV: 71% and NPV: 86%. In the same patients, sensitivity and specificity of the sequential diagnostic algorithm increased to 80% and 97%, showing significantly better global accuracy (92% vs. 83%) than standard PET/CT.
Conclusions
We support a personalized imaging algorithm for pHPT, placing [18F]Fluorocholine PET/CT at the forefront, followed by 4D-CT integrated into PET/4D-CT in the same imaging session for negative/inconclusive results. When PET/CT results are clearly positive, the additional sensitivity benefit of 4D-CT is minimal.

Objective
Eosinophilic granulomatous polyangiitis (EGPA) is a rare autoimmune disease characterized by multisystemic inflammation, with eosinophils playing a central role in its pathogenesis. Traditional management relies heavily on corticosteroids and immunosuppressants, which are associated with significant side effects. The emergence of biologic agents, such as benralizumab, offers targeted therapeutic options by inhibiting the interleukin-5 receptor α, thereby reducing eosinophilic inflammation.
Methods
This systematic review and meta-analysis comprehensively evaluate the efficacy and safety of benralizumab in EGPA patients, focusing on its ability to reduce oral corticosteroid (OCS) use, facilitate remission and spare immunosuppressants. We searched MEDLINE, LILACS and ISI Web of Science databases for relevant studies up to July 2024.

Eight studies, including both randomized controlled trials (RCTs) and observational studies, were included in the meta-analysis, involving a total of 396 EGPA patients. The pooled analysis demonstrated a significant reduction in OCS dose, with an overall estimated effect of −8.25 mg/day (95% CI, −9.39 to −7.10). Complete remission was achieved in 56.8% of patients, and immunosuppressants were reduced or discontinued in 28.1% of cases. Adverse events (AEs) were reported in 21.9% of patients, with only one discontinuation due to an AE.
Conclusion
These findings provide robust evidence supporting the use of benralizumab as an effective and well-tolerated treatment option for EGPA, significantly reducing OCS requirements and offering promising remission rates. Future research should focus on larger, multicentre RCTs to confirm these findings and further elucidate the long-term benefits and safety profile of benralizumab in EGPA.
目的:嗜酸性粒细胞肉芽肿性多血管炎(EGPA)是一种罕见的自身免疫性疾病,以多系统炎症为特征,嗜酸性粒细胞在其发病机制中起着核心作用。传统的治疗方法主要依赖皮质类固醇和免疫抑制剂,但副作用很大。benralizumab等生物制剂的出现通过抑制白细胞介素-5受体α,从而减轻嗜酸性粒细胞炎症,提供了靶向治疗选择:本系统综述和荟萃分析全面评估了苯拉利珠单抗对 EGPA 患者的疗效和安全性,重点关注其减少口服皮质类固醇(OCS)用量、促进病情缓解和避免使用免疫抑制剂的能力。我们检索了MEDLINE、LILACS和ISI Web of Science数据库中截至2024年7月的相关研究:荟萃分析纳入了八项研究,包括随机对照试验(RCT)和观察性研究,共涉及 396 名 EGPA 患者。汇总分析表明,OCS剂量显著减少,总体估计效果为-8.25毫克/天(95% CI,-9.39至-7.10)。56.8%的患者获得了完全缓解,28.1%的病例减少或停用了免疫抑制剂。21.9%的患者出现了不良事件(AE),只有1例患者因AE而停药:这些研究结果提供了有力的证据,支持使用苯拉利珠单抗作为治疗EGPA的一种有效且耐受性良好的治疗方案,可显著减少OCS需求,并提供可喜的缓解率。未来的研究应侧重于更大规模的多中心 RCT,以证实这些发现,并进一步阐明 Benralizumab 治疗 EGPA 的长期疗效和安全性。

Ischemia/reperfusion injury is attracting continuous interest in science for two reasons: because it affects several clinical conditions and because it has been identified, albeit in broad terms, the molecular entity becoming activated by the reperfusion damage paradoxes.

缺血/再灌注损伤正引起科学界的持续关注,原因有二:一是它影响着多种临床症状;二是它已被确定为再灌注损伤悖论所激活的分子实体,尽管只是广义上的。事实上,钙、氧依赖性氧化应激和 pH 会激活线粒体嵴中嵌入的 F1/FO ATP 合酶的构象变化,使线粒体内膜形成孔隙,从而增加其通透性。这是决定线粒体压力、细胞死亡和组织功能障碍的关键因素。针对这些因素中的每一个进行治疗都无助于改善受再灌注损伤影响的患者的临床预后;现在,关注 PTP 开放可能是解决组织血管再通时造成大量细胞死亡这一途径的最接近目标。在这篇综述中,我们总结了有关 PTP 结构、调节和治疗靶点的最新知识,重点关注 ATP 合酶和心脏缺血/再灌注。

Introduction
The use of medications by emergency medical services (EMS) is increasing. Conventional scores are time-consuming and therefore difficult to use in an emergency setting. For early decision-making, an easy-to-use score based on the medications administered by the EMS may have prognostic value. The primary objective of this study was to develop the prehospital drug-derived score (PDDS) for 2-day mortality.
Methods
A prospective, multicenter, ambulance-based cohort study was conducted in adults with undifferentiated acute diseases treated by EMS and transferred to the emergency department. Demographic data, prehospital diagnosis data, prehospital medication and variables for the calculation of the National Early Warning Score 2 (NEWS2), Rapid Emergency Medicine Score (REMS), and Rapid Acute Physiology Score (RAPS) were collected. The PDDS was developed and validated, establishing three levels of risk of 2-day mortality. The predictive capability of each score was determined by the area under the curve of the receiver operating characteristic curve (AUROC) and compared using the Delong's test (p-value).
Results
A total of 6401 patients were included. The PDDS included age and the use of norepinephrine, analgesics, neuromuscular blocking agents, diuretics, antihypertensive agents, tranexamic acid, and bicarbonate. The AUROC of PDDS was .86 (95% CI: .816–.903) versus NEWS2 .866 (95% CI: .822–.911), p = .828; versus REMS .885 (95% CI: .845–.924), p = .311; versus RAPS .886 (95% CI: .846–.926), p = .335, respectively.
Conclusion
The newly developed easy-to-use prehospital drug-derived PDDS score has an excellent predictive value of early mortality. The PDDS score was comparable to the conventional risk scores and therefore might serve as an alternative score in the prehospital emergency setting.

Background
Platelet receptors ACKR3 and CXCR4 play a crucial role in a variety of cardiovascular diseases. Like most chemokine receptors, CXCR4 is a G protein coupled receptor that induces platelet activation. In contrast, the atypical chemokine receptor 3 (ACKR3) lacks the ability to activate heterotrimeric G proteins and its activation leads to platelet inhibition and attenuates thrombus formation. In nucleated cells, heterodimerization of ACKR3 with CXCR4 regulates CXCL12-dependent signalling. The aim of our study was to investigate the formation of ACKR3/CXCR4 heterodimers in platelets and the subsequent consequences for platelet function.
Methods and Results
Using a proximity ligation assay (PLA, Duolink®) to screen for CXCR4/ACKR3 heterodimerization inducing compounds, we found that ACKR3 agonism but not conventional platelet agonists or endogen ligands lead to heterodimer formation. To further characterize the formation of ACKR3/CXCR4 heterodimers, we studied the CXCL12-dependent platelet activation via CXCR4. Both, CXCL12-dependent platelet aggregation and collagen-dependent ex vivo thrombus formation were significantly downregulated by ACKR3 agonism. Moreover, platelet intracellular calcium and Akt signalling were increased by CXCL12 and again suppressed by ACKR3-specific agonists. Previously, CXCL12 was shown to decrease platelet cAMP levels via CXCR4. Treatment with a specific ACKR3 agonist counteracted this CXCL12/CXCR4-dependent cAMP decrease.
Conclusion
Our results reveal that the formation of platelet ACKR3/CXCR4 heterodimers is dependent on ACKR3 rather than CXCR4. Furthermore, ACKR3 agonism induced heterodimerization is associated with mitigating CXCL12/CXCR4-dependent platelet activation possibly by modulating CXCR4-dependent G protein signalling. Our results indicate possible ACKR3 agonist functions and reinforce the potential therapeutic applications of ACKR3 agonists.

Background
Maintaining low concentrations of plasma low-density lipoprotein cholesterol (LDLc) over time decreases the number of LDL particles trapped within the artery wall, slows the progression of atherosclerosis and delays the age at which mature atherosclerotic plaques develop. This substantially reduces the lifetime risk of atherosclerotic cardiovascular disease (ASCVD) events. In this context, plaque development and vulnerability result not only from lipid accumulation but also from inflammation.
Results
Changes in the composition of immune cells, including macrophages, dendritic cells, T cells, B cells, mast cells and neutrophils, along with altered cytokine and chemokine release, disrupt the equilibrium between inflammation and anti-inflammatory mechanisms at plaque sites. Considering that it is not a competition between LDLc and inflammation, but instead that they are partners in crime, the present narrative review aims to give an overview of the main inflammatory molecular pathways linked to raised LDLc concentrations and to describe the impact of lipid-lowering approaches on the inflammatory and lipid burden. Although remarkable changes in LDLc are driven by the most recent lipid lowering combinations, the relative reduction in plasma C-reactive protein appears to be independent of the magnitude of LDLc lowering.
Conclusion
Identifying clinical biomarkers of inflammation (e.g. interleukin-6) and possible targets for therapy holds promise for monitoring and reducing the ASCVD burden in suitable patients.
