Assessing the benefit-risk profile of newer glucose-lowering drugs: A systematic review and network meta-analysis of randomized outcome trials

AIM

To comprehensively evaluate the benefits and risks of glucagon-like peptide-1 receptor agonists (GLP-1RA), dipeptidyl peptidase 4 inhibitors (DPP4i), and sodium-glucose cotransporter 2 inhibitors (SGLT2i).

MATERIALS AND METHODS

A systematic search of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to November 2023 to identify randomized cardiovascular and kidney outcome trials that enrolled adults with type 2 diabetes, heart failure, or chronic kidney disease and compared DPP4i, GLP-1RAs, or SGLT2i to placebo. Twenty-one outcomes (e.g., major adverse cardiovascular events [MACE], stroke, and hospitalization for heart failure [HHF]) were assessed. Data were pooled using population-averaged odds ratios (ORs) with 95% CIs.

RESULTS

Twenty-six trials enrolling 198 177 participants were included. GLP-1RAs were most effective in lowering the risks of MACE (OR, 0.85, [95% CI, 0.79 to 0.92]) and stroke (0.84 [0.77, 0.91]), but increased the risk of thyroid cancer (1.58 [1.36, 2.50]). SGLT2i showed the greatest benefits in reducing the risk of HHF (0.68 [0.64, 0.73]) and improving composite renal outcomes (0.67 [0.58, 0.77]), but increased the risk of genital infections (3.11 [2.15, 4.50]). DPP4i were associated with a lower risk of certain psychiatric disorders, Parkinson's disease (0.54 [0.32, 0.92]), and amputation (0.70 [0.86, 0.93]), but an increased risk of neuropathy (1.10 [1.02, 1.18]) and pancreatitis (1.63 [1.40, 1.91]). The weighted origami plot suggested that GLP-1RAs were more suitable for reducing macrovascular and microvascular outcomes, while DPP4i might be better for neurodegenerative diseases and cancer concerns.

CONCLUSIONS

Given the distinct benefit-risk profiles, the selection of glucose-lowering drugs should be individualized based on patient characteristics and risk factors.

Impact on ventricular arrhythmic burden of SGLT2 inhibitors in patients with chronic heart failure evaluated with cardiac implantable electronic device monitoring

BACKGROUND

Sodium-glucose cotransporter 2 (SGLT2) inhibitors have revolutionized the therapeutic scenario of heart failure, demonstrating favorable effects on mortality and quality of life. Previous studies have yielded conflicting data regarding the effects on ventricular arrhythmias.

METHODS

A prospective observational study was conducted to investigate the anti-arrhythmic properties of SGLT2 inhibitors evaluating the intra-patient difference in major adverse arrhythmic cardiac events (MAACE) over a six-month period in patients with chronic heart failure who were undergoing continuous monitoring using a cardiac implantable electronic device.

RESULTS

From January 2022 to January 2023, 82 patients [median age 63 years (IQR 15), male 87 %] were enrolled in the study, with a median follow-up of 28 weeks (IQR 5). The rate of MAACE at baseline was 11 %, without relevant differences in the follow up in terms of major and minor arrhythmic events. In patients with an arrhythmic phenotype at baseline, a mild but non statistically significant reduction of MAACE (from 36 % to 28 %, p = 0.727) was observed and a significant decrease of non-sustained ventricular tachycardia (from 68 % to 32 %, p = 0.022).

CONCLUSIONS

Our findings suggest potential anti-arrhythmic properties of SGLT2 inhibitors, evident in patients with arrhythmic events before the initiation of the drug.

Long-term rate of heart failure in patients with autoimmune disease: A nationwide cohort study

AIMS

Although certain autoimmune diseases (AIDs) have been associated with an increased rate of heart failure (HF), data on the long-term rate of HF across the spectrum of AIDs are lacking. We investigated the long-term rate of HF in individuals with a history of 28 different AIDs.

METHODS AND RESULTS

Individuals diagnosed with an AID (2000-2021) were identified through Danish nationwide registries. Each patient with AID was matched with four individuals from the background population by age, sex, and year of inclusion. Multivariable Cox regression was used to compare the rate of HF between the AID and the background population, overall and according to individual AIDs. In total, 272 959 patients diagnosed with AID were matched with 1 091 836 individuals without AID (median age 55 years; 62% women; median follow-up 7.9 years). The 10-year cumulative incidence of HF was 5.2% for patients with AID and 3.5% for matched individuals. Patients with any AID had a higher associated rate of HF than matched individuals (hazard ratio [HR] 1.55, 95% confidence interval [CI] 1.52-1.59). Patients with each of the AIDs had a higher associated rate of incident HF compared with matched individuals from the background population, although the association was not statistically significant for Reiter's and Behcet's disease. The highest relative rates were observed in patients with systemic sclerosis (HR 3.31, 95% CI 2.63-4.16) and Addison's disease (HR 3.03, 95% CI 2.35-3.91).

CONCLUSION

Patients with AID, irrespective of the type, had a higher associated rate of HF compared to the background population. Further research is needed to clarify whether screening for cardiovascular risk is beneficial.

Cutting-Edge Approaches to Obesity Management: The Latest Pharmacological Options

Successful treatment of obesity requires a multidisciplinary approach including dietary strategy, physical activity, and behavioral modification. The seven FDA-approved anti-obesity medications are phentermine, orlistat, phentermine/topiramate ER, naltrexone SR/bupropion SR, liraglutide 3.0 mg, semaglutide 2.4 mg, and tirzepatide. Obesity is a chronic disease and these medications should be prescribed with the intention of long-term use. In this article, we summarize data from phase 3 clinical trials which led to drug approval, and we review the clinical indications, mechanism of action, dosing/administration, side effects, drug interactions and contraindications for each medication.

Multi-omic profiling of sarcopenia identifies disrupted branched-chain amino acid catabolism as a causal mechanism and therapeutic target

Sarcopenia is a geriatric disorder characterized by a gradual loss of muscle mass and function. Despite its prevalence, the underlying mechanisms remain unclear, and there are currently no approved treatments. In this study, we conducted a comprehensive analysis of the molecular and metabolic signatures of skeletal muscle in patients with impaired muscle strength and sarcopenia using multi-omics approaches. Across discovery and replication cohorts, we found that disrupted branched-chain amino acid (BCAA) catabolism is a prominent pathway in sarcopenia, which leads to BCAA accumulation and decreased muscle health. Machine learning analysis further supported the causal role of BCAA catabolic dysfunction in sarcopenia. Using mouse models, we validated that defective BCAA catabolism impairs muscle mass and strength through dysregulated mTOR signaling, and enhancing BCAA catabolism by BT2 protects against sarcopenia in aged mice and in mice lacking Ppm1k, a positive regulator of BCAA catabolism in skeletal muscle. This study highlights improving BCAA catabolism as a potential treatment of sarcopenia.

Extracellular vesicles in atherosclerosis: Current and forthcoming impact

Atherosclerosis is the main pathogenic substrate for cardiovascular diseases (CVDs). Initially categorized as a passive cholesterol storage disease, nowadays, it is considered an active process, identifying inflammation among the key players for its initiation and progression. Despite these advances, patients with CVDs are still at high risk of thrombotic events and death, urging to deepen into the molecular mechanisms underlying atherogenesis, and to identify novel diagnosis and prognosis biomarkers for their stratification. In this context, extracellular vesicles (EVs) have been postulated as an alternative in search of novel biomarkers in atherosclerotic diseases, as well as to investigate the crosstalk between the cells participating in the processes leading to arterial remodelling. EVs are nanosized lipidic particles released by most cell types in physiological and pathological conditions, that enclose lipids, proteins, and nucleic acids from parental cells reflecting their activation status. First considered cellular waste disposal systems, at present, EVs have been recognized as active effectors in a myriad of cellular processes, and as potential diagnosis and prognosis biomarkers also in CVDs. This review summarizes the role of EVs as potential biomarkers of CVDs, and their involvement into the processes leading to atherosclerosis.

Impella support for refractory cardiogenic shock accompanied by diabetic ketoacidosis: a case report

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are strongly recommended in patients with heart failure, regardless of the presence of diabetes mellitus. A 74 year-old woman with a reduced left ventricular ejection fraction and diabetes mellitus (the types were unknown), receiving insulin and SGLT2 inhibitor, was hospitalized for altered consciousness with systemic hypotension. Upon admission, she was diagnosed with cardiogenic shock due to diabetic ketoacidosis. Intensive fluid resuscitation under Impella CP support successively improved her metabolic acidosis, preventing worsening pulmonary congestion by mechanically unloading the heart. After hemodynamic stabilization, she was diagnosed with type 1 diabetes mellitus for the first time. She was discharged on day 54 and was followed for 6 months without any recurrences. We must remain vigilant regarding the risk of diabetic ketoacidosis in patients using SGLT2 inhibitors, particularly those on insulin therapy or with diabetes mellitus of unknown types. Impella device shows promise as a circulatory support system in alleviating the left ventricle's workload and averting exacerbated pulmonary congestion, especially in cases where patients necessitate aggressive fluid replacement therapy, such as in the treatment of diabetic ketoacidosis concurrent with compromised cardiac function.

Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitor- and Metformin-Associated Euglycemic Diabetic Ketoacidosis and Lactic Acidosis Leading to Refractory Acute Kidney Injury: Successful Management With Hemodialysis

Euglycemic diabetic ketoacidosis (EuDKA) is a rare but serious complication of sodium-glucose cotransporter 2 (SGLT2) inhibitors, characterized by metabolic acidosis with near-normal blood glucose levels, making it challenging to diagnose. This case report describes a 49-year-old male with stage 4 chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM) on an SGLT2 inhibitor and metformin who developed EuDKA and lactic acidosis following an upper respiratory infection. Despite discontinuation of the medications and intravenous fluid resuscitation, severe metabolic acidosis persisted. Early initiation of hemodialysis led to rapid correction of acidemia, hyperkalemia, and improvement in renal function. This case highlights the importance of early recognition of SGLT2 inhibitor-associated EuDKA, particularly when complicated by lactic acidosis, and emphasizes the potential role of hemodialysis in managing refractory metabolic acidosis to prevent further clinical deterioration, even with modest hyperglycemia.

GLP-1RA Use and Thyroid Cancer Risk

Importance

The increasing use of glucagon-like peptide-1 receptor agonists (GLP-1RA) demands a better understanding of their association with thyroid cancer.

Objective

To estimate the risk of incident thyroid cancer among adults with type 2 diabetes being treated with GLP-1RA vs other common glucose-lowering medications.

Design, Setting, and Participants

This was a prespecified secondary analysis of a target trial emulation of a comparative effectiveness study using claims data for enrollees in commercial, Medicare Advantage, and Medicare fee-for-service plans across the US. Eligible participants were adults with type 2 diabetes at moderate risk for cardiovascular disease and without history of thyroid cancer who had newly filled prescriptions for GLP-1RA, sodium-glucose cotransporter 2 inhibitor (SGLT2i), dipeptidyl peptidase-4 inhibitor (DPP4i), or sulfonylurea from January 1, 2014, to December 31, 2021. Data were analyzed February 1 to October 31, 2024.

Main Outcomes and Measures

Overall and piecewise (<1, 1-2, and ≥2 years since treatment initiation) hazard ratios (HRs) for thyroid cancer with use of GLP-1RA vs the other 3 drug classes were estimated using inverse propensity score weighted Cox proportional hazards models. Modified intention-to-treat (mITT) (primary) and as-treated (sensitivity) analyses were performed.

Results

Of 351 913 patients (mean [SD] age, 65.3 [8.5] years; 173 391 [49.3%] females and 178 522 [50.7%] males), 41 112 started treatment with GLP-1RA; 76 093, with DPP4i; 43 499, with SGLT2i; and 191 209, with sulfonylurea therapy. The numbers of patients diagnosed with thyroid cancer were 69 (0.17%) in the GLP-1RA group, 172 (0.23%) in the DPP4i group, 72 (0.17%) in the SGLT2i group, and 381 (0.20%) in the sulfonylurea group. In the mITT analysis, GLP-1RA initiation was not significantly associated with increased overall risk for thyroid cancer compared to the other 3 diabetes drugs (HR, 1.24; 95% CI, 0.88-1.76). However, the risk for thyroid cancer was significantly higher within the first year after GLP-1RA initiation (HR, 1.85; 95% CI, 1.11-3.08) and was amplified in the overall as-treated analysis that censored patients when therapy was discontinued or another medication was added (HR, 2.07; 95% CI, 1.10-3.95).

Conclusions and Relevance

This secondary analysis of a target trial emulation of a comparative effectiveness study found that despite the low absolute risk of thyroid cancer among patients receiving GLP-1RA therapy, there was an increased risk of new thyroid cancer diagnoses within the first year of GLP-1RA initiation compared to 3 other diabetes drugs. This finding may have been due to enhanced early detection; therefore, further research is necessary to understand the underlying causes of this association.

Strides towards healthy longevity: Harnessing the power of sports and elements of Kathak, an Indian classical dance form through social participation to combat cognitive frailty among older adults

Aging brings with it many health issues that can make life challenging. As much of the attention is given to non-communicable diseases, there are others which are slowly becoming a matter of great concern. One such issue is cognitive frailty, which is a high risk factor for dementia, falls, fractures and hospitalization. Though not yet declared a public health concern, it deserves early detection and prevention strategies. As it is reversible if treated on time, there is a need to look into its prevention and cure. Physical activity has proven to be very effective in the treatment of cognitive frailty. This scoping review thus aims to study the impact of physical activity through social participation on cognitive frailty. The authors recommend that focussing on one's muscular fitness through participation in sports and elements of Indian classical dance form like Kathak in groups/ communities can be a very effective way of combating cognitive frailty among older adults.

Digital Health Technology in Diabetes Management in the Asia-Pacific Region: A Narrative Review of the Current Scenario and Future Outlook

Diabetes is a growing global health concern with a high prevalence in the Asian and Western Pacific regions. Effective diabetes management mainly relies on self-care practices. However, glycemic control remains poor, especially in developing nations where healthcare access is limited. Low physician density and minimal healthcare funding exacerbate the challenges faced by people with diabetes in Asia. Digital health technologies offer promising solutions to bridge these gaps. These technologies enhance patient engagement, improve medication adherence, and promote healthier lifestyles. Mobile apps provide tools for self-management, such as monitoring physical activity and dietary intake, while telemedicine platforms and electronic medical records facilitate patient data management and remote consultations. Despite the advantages provided by digital health technologies in managing diabetes, barriers to their adoption include infrastructure limitations, regulatory challenges, and issues with data security. Some Asian countries have made major strides in the adoption of digital health tools with national strategies and regulatory bodies to manage digital health options; however, disparities in digital health readiness persist. Effective implementation of these technologies requires addressing these barriers, including enhancing infrastructure, improving app usability, and ensuring regulatory compliance. While digital health solutions present significant opportunities, their impact depends on overcoming current challenges and ensuring equitable access and effective use in managing diabetes. Future directions should focus on prioritizing app acceptance and efficacy, as well as integrating machine learning and artificial intelligence-powered digital solutions.

Metabolomics Reveal the Anti-Hyperuricemia Effects and Mechanisms of Sunflower Head Extract in Hyperuricemia Mice Model

Hyperuricemia (HUA) is a globally prevalent metabolic disease characterized by excessive production or insufficient excretion of uric acid in the serum. Although several drugs are available for the treatment of HUA, they have been associated with undesirable side effects. Therefore, this study aims to evaluate the therapeutic effects of sunflower head extract (KHE) on HUA in a mouse model and explore its potential mechanisms. All mice were randomly divided into three groups: Normal control (NC, 0.5% CMC-Na), HUA model (MD, yeast extract paste 20 g/kg), and KHE treatment group (KHE, 1 g/kg). Biochemical indicators, the oxidative stress state, and metabolomics were analyzed. KHE reduced the levels of 5-aminoimidazole ribonucleotide, xanthine, hypoxanthine, and uric acid in the serum of mice with HUA but increased the levels of adenine and taurine. KHE decreased the activities of superoxide dismutase (SOD) enzymes, the hepatic hydrogen peroxide (H2O2) and malondialdehyde (MDA) levels, and the serum levels of betaine aldehyde and beta-D-glucosamine. KHE improved oxidative stress levels and mitigated potential damage to the kidneys and joints caused by urate deposition. These findings provide comprehensive evidence supporting the anti-HUA effects and underlying mechanisms of KHE in HUA mice.

Association between optimum blood glucose level and mortality in critically ill patients with septic shock: A real-world time-series data analysis

BACKGROUND

Sepsis remains a significant health challenge in ICU, with septic shock requiring meticulous glycaemic management due to metabolic dysregulation. Existing research highlights the detrimental effects of both hyperglycaemia and hypoglycaemia on septic patient outcomes, emphasizing the need for effective glycaemic control. Despite extensive studies, optimal glycaemic targets in septic shock patients remain contentious and unclear, necessitating further research.

AIM

Our study aims to identify optimal glycaemic targets for patients in septic shock by analysing time-series blood glucose data.

STUDY DESIGN

This retrospective observational study utilized the MIMIC-IV database, encompassing ICU patients diagnosed with septic shock from 2008 to 2019. We extracted time-series blood glucose data and applied the Stineman interpolation to achieve a standardized resolution. The primary analysis involved calculating the time-weighted average blood glucose (TWA-BG) and examining its relationship with 28-day mortality using a restricted cubic spline model within a Cox regression framework. Sensitivity analyses with multiple models and subgroup analyses were used to reveal the robustness of the results.

RESULTS

From 34 677 identified septic patients, 11 375 met the inclusion criteria. The optimal TWA-BG range, associated with the lowest 28-day mortality risk, was determined to be 105 to 131 mg/dL. Patients within this range exhibited significantly lower mortality rates compared to those with higher or lower TWA-BG levels. Sensitivity analyses confirmed these findings, indicating robustness across various subgroups and analytical models.

CONCLUSIONS

Our findings suggest that maintaining TWA-BG levels between 105 and 131 mg/dL minimizes the risk of 28-day, ICU, and in-hospital mortality in patients with septic shock.

RELEVANCE TO CLINICAL PRACTICE

The results provide evidence-based guidance for ICU nursing interventions, advocating for a precise TWA-BG range to be maintained for septic shock patients, thus potentially setting new benchmarks for glycaemic control in critical care settings.

Sodium-glucose co-transporter 2 inhibitors: a pleiotropic drug in humans with promising results in cats

Diabetes mellitus is a common metabolic disease in humans and cats. Cats share several features of human type-2 diabetes and can be considered an animal model for this disease. In the last decade, sodium-glucose transporter 2 inhibitors (SGLT2i) have been used successfully as a class of hypoglycemic drug that inhibits the reabsorption of glucose from the renal proximal tubules, consequently managing hyperglycemia through glycosuria. Furthermore, SGLT2i have been shown to have cardiac, renal, and other protective effects in diabetic humans acting as a pleiotropic drug. Currently, at least six SGLT2i are approved by the Food and Drug Administration (FDA) for use in humans with type-2 diabetes, and recently, two drugs were approved for use in diabetic cats. This narrative review focuses on the use of SGLT2i to treat diabetes mellitus in humans and cats. We summarize the human data that support the use of SGLT2i in controlling type-2 diabetes and protecting against cardiovascular and renal damage. We also review the available literature regarding other benefits of these drugs in humans as well as the effects of SGLT2i in cats. Adverse effects related to the use of these hypoglycemic drugs are also discussed.

The Impact of SGLT-2 Inhibitors on Hydroxyl Radical Markers and Diabetic Neuropathy: A Short-Term Clinical Study

Beyond their metabolic effect, sodium-glucose cotransporter-2 (SGLT-2) inhibitors reduce the risk of heart failure and have cardiovascular and nephroprotective effects, yet their exact mechanism of action remains unclear. This prospective study included 40 patients with type 2 diabetes whose physician initiated SGLT-2 inhibitor therapy. Prior to and 4 weeks after the initiation of SGLT-2 inhibitors, in addition to routine clinical and laboratory measurements, hydroxyl free radical and neuropathic evaluations were performed. Body weight, body mass index (BMI), fasting glucose, fructosamine, and albuminuria decreased significantly, whereas red blood cell (RBC) count, hemoglobin, hematocrit, mean corpuscular volume (MCV), and platelet count increased significantly. Urinary o-tyrosine/p-tyrosine and (m-tyrosine+o-tyrosine)/p-tyrosine ratios were significantly reduced, suggesting diminished hydroxyl free radical production. Patients with neuropathy, identified by abnormal baseline current perception threshold (CPT) values, showed significant improvements. Significant correlations between RBCs, platelet parameters, albuminuria, and hydroxyl free radical markers disappeared after SGLT-2 treatment and changes in hydroxyl free radical markers correlated positively with CPT changes. Our results suggest that short-term SGLT-2 inhibition recalibrates metabolic, hematologic, renal, and neuropathic endpoints simultaneously, presumably through attenuating abnormal ortho- and meta-tyrosine incorporation into signaling proteins. Further studies are required to confirm long-term durability and examine whether additional strategies, such as supplementation of the physiological p-tyrosine, could amplify these benefits.

The anti-neuroinflammatory effects of cepharanthine in uric acid-induced neuroinflammation

ETHNOPHARMACOLOGICAL RELEVANCE

Cepharanthine (CEP) is an alkaloid extracted from Stephania cephalantha Hayata, a traditional Chinese medicine (TCM) renowned for its heatclearing and dehumidifying properties. For centuries, Stephania cephalantha Hayata has been employed in the treatment of a wide range of diseases, including pain, edema, inflammation, and fever.

AIM OF THE STUDY

Our research aims to investigate the role and mechanism of Cepharanthine in ameliorating uric acid (UA) induced neuroinflammatory responses.

MATERIALS AND METHODS

The Connectivity Map (CMap) was utilized to identify the therapeutic drug Cepharanthine, based on the proteomic disturbances associated with uric acid (UA). Limited proteolysis small molecule mapping (LiP-SMap) and thermal proteome profiling (TPP) technologies were used to identify the direct target proteins for UA and Cepharanthine. Additionally, we used the induced-fit docking algorithm integrated within the Schrodinger suite to explore the interactions between Cepharanthine and uric acid targets. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology was employed to determine the concentration of Cepharanthine in the mice cerebral cortex. The pro-inflammatory cytokine genes were also quantified by qPCR in U251 cells and in hyperuricemic mice.

RESULTS

The findings indicated that uric acid increased the transcription of pro-inflammatory cytokines and the expression levels of proteins linked to inflammation in U251 cells. PPP2R1A was identified as a potential candidate for direct interaction with uric acid, potentially initiating inflammation. Based on the CMap prediction, Cepharanthine was identified as a candidate drug for interaction with PPP2R1A. TPP analysis indicated that Cepharanthine could reduce the thermal stability of PPP2R1A. Molecular docking confirmed that Cepharanthine could directly bind to PPP2R1A. Furthermore, the detection of Cepharanthine in the cerebral cortex suggested its ability to cross the blood-brain barrier. Proteomic analysis of Cepharanthine-treated mice revealed significant enrichments of differentially expressed proteins (DEPs) in inflammation-related pathways and biological processes. Additionally, Cepharanthine was effective in decreasing the expression of pro-inflammatory cytokine genes induced by uric acid in U251 cells and in hyperuricemic mice.

CONCLUSION

Cepharanthine could effectively alleviate hyperuricemia-induced neuroinflammation via binding to PPP2R1A. This study offers a novel approach for prevention and treatment of neurological diseases caused by hyperuricemia.

Efficacy and safety of 11 sodium-glucose cotransporter-2 inhibitors at different dosages in type 2 diabetes mellitus patients inadequately controlled with metformin: a Bayesian network meta-analysis

OBJECTIVES

Assess the efficacy and safety profiles of different sodium-glucose cotransporter-2 inhibitors (SGLT2is) as an add-on to metformin in type 2 diabetes mellitus (T2DM) patients.

DESIGN

Bayesian network meta-analysis.

DATA SOURCES

PubMed, Embase, Cochrane Library, Web of Science and ClinicalTrials.gov were searched before 18 December 2024.

ELIGIBILITY CRITERIA

Randomised controlled trials (RCTs) evaluating T2DM patients taking one of 12 SGLT2is as add-on therapy to metformin. Efficacy outcomes focused on glycated haemoglobin (HbA1c) reduction, fasting plasma glucose (FPG) reduction and weight loss (WL). Safety outcomes included adverse events (AEs), serious AEs (SAEs), hypoglycaemia, urinary tract infections (UTI) and genital infections (GI).

DATA EXTRACTION AND SYNTHESIS

Two investigators independently extracted data. The quality of the included studies was assessed using the Cochrane Risk of Bias Tool (V.2.0) for RCTs.

RESULTS

23 RCTs involving 9144 patients and 11 SGLT2is were included. Compared with placebo, most SGLT2is reduced HbA1c (mean difference (MD), -0.45~-0.80%), FPG (MD, -0.78~-2.02 mmol/L) and body weight (MD, -0.88~-2.67 kg). Only 10 mg of henagliflozin increased the incidence of AEs, and none of the included interventions increased the risks of SAEs or UTIs. 50 mg of empagliflozin exhibited higher risks of hypoglycaemia. Only 10 mg of empagliflozin increased the risk of GI. According to the surface under the cumulative ranking values, SGLT2is with optimal efficacy and safety were 15 mg of ertugliflozin in HbA1c reduction, 300 mg of canagliflozin in FPG reduction, WL and hypoglycaemia, 400 mg of sotagliflozin in total AEs, 10 mg of ertugliflozin and 150 mg of ipragliflozin in SAEs, 12.5 mg of ipragliflozin in UTI and 1 mg of ertugliflozin in GI.

CONCLUSIONS

As add-on therapy, SGLT2is demonstrated favourable antidiabetic efficacy and acceptable safety. 300 mg of canagliflozin was the best option among the included interventions considering favourable glucose control and WL. Some novel SGLT2is (eg, henagliflozin) exhibited promising efficacy and safety profiles, but more research is needed to validate the findings.

Time-varying cost-effectiveness analysis of sodium-glucose cotransporter-2 inhibitors in Chinese patients with heart failure and reduced ejection fraction: A microsimulation of the real-world population

Objective

Sodium-glucose cotransporter-2 (SGLT2) inhibitors showed time-varying effects in heart failure and reduced ejection fraction (HFrEF), but corresponding cost-effectiveness in different timeframes remained poorly understood. This study estimated the time-varying cost-effectiveness of SGLT2 inhibitors in HFrEF from the perspective of the Chinese healthcare system.

Methods

Based on real-world individual patient data, a 2-year microsimulation model was constructed to evaluate the cost-effectiveness of adding SGLT2 inhibitors to standard therapy compared with standard therapy alone among patients with HFrEF. A published prediction model informed transition probabilities for all-cause death and hospitalization for heart failure. The time-varying effects of SGLT2 inhibitors, medical costs, and utility values were derived from the published literature. Scenario analyses in different timeframes were conducted to assess the trend of cost-effectiveness over time.

Results

Compared with standard therapy alone, SGLT2 inhibitors plus standard therapy were found cost-effective at a willingness-to-pay (WTP) threshold of $12,741 per quality-adjusted life year (QALY) gained in 2 years. The incremental cost-effectiveness ratio (ICER) decreased from $12,346.07/QALY at 0.5 years to $9,355.66/QALY at 2 years. One-direction sensitivity analysis demonstrated that the cost-effectiveness of SGLT2 inhibitors was most sensitive to the cost of SGLT2 inhibitors, the cost of hospitalization for heart failure, the cost of standard therapy for heart failure, and the baseline risks of all-cause death and hospitalization for heart failure. Probabilistic sensitivity analysis proved the robustness of the results.

Conclusion

Adding SGLT2 inhibitors to standard therapy was found to be cost-effective in Chinese patients with HFrEF. Longer treatment appeared to be more economically favorable, but further explorations are warranted.

2025 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2025 AHA Statistical Update is the product of a full year's worth of effort in 2024 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. This year's edition includes a continued focus on health equity across several key domains and enhanced global data that reflect improved methods and incorporation of ≈3000 new data sources since last year's Statistical Update.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Effects of Sodium-Glucose Cotransporter 2 Inhibitors on Nervous System Disorders: A Systematic Review and Meta-Analysis

BACKGROUND

Adults with type 2 diabetes mellitus (T2DM) are at an increased risk for certain brain or psychiatric disorders, as are those with or without chronic kidney disease or heart failure. Whether sodium-glucose cotransporter 2 (SGLT2) inhibitors are associated with these diseases is unclear.

OBJECTIVE

This systematic review and meta-analysis aimed to investigate the effects of SGLT2 inhibitors on nervous system disorders.

METHODS

We searched PubMed, ClinicalTrials.gov, and Web of Science for randomized, double-blind placebo-controlled trials of at least ≥24 weeks. We used Mantel-Haenszel statistical method, risk ratio (RR), and 95% confidence interval (CI) to dichotomous variables.

RESULTS

We included 52 publications/trials covering 111 376 participants (SGLT2 inhibitors 62 192; Placebo 49 184). Sodium-glucose cotransporter 2 inhibitors had no significant effect on ischaemic stroke (RR = 0.97; 95% CI = 0.87-1.09; P = 0.64), cerebrovascular accident (RR = 1.05; 95% CI = 0.91-1.22; P = 0.50), dementia (RR = 1.29; 95% CI = 0.78-2.12; P = 0.32), carotid artery occlusion/carotid artery stenosis (RR = 1.18; 95% CI: 0.92-1.53; P = 0.20), haemorrhagic stroke (RR = 0.84; 95% CI = 0.62-1.12; P = 0.23), and transient ischaemic attack (RR = 0.97; 95% CI = 0.82-1.15; P = 0.73) compared to placebo. No significant heterogeneity was observed. However, SGLT2 inhibitors showed slight effects to reduce the risk of Parkinson's disease (major heart failure subgroup). Empagliflozin and dapagliflozin significantly increased the risk of syncope (RR = 1.65; 95% CI = 1.15-2.38; P < 0.01) and carotid artery occlusion/carotid artery stenosis (RR = 1.65; 95% CI = 1.04-2.61; P = 0.03), respectively.

CONCLUSION AND RELEVANCE

No significant effect of SGLT2 inhibitors on nervous system disorders was observed. There was reduced risk for Parkinson's Disease observed in some specific populations. In addition, the risks of empagliflozin and dapagliflozin concerning syncope and carotid artery occlusion/carotid artery stenosis are worth attention.

Intention of smartphone application usage in diabetes self-management and its associated factors among patients with diabetes: A cross-sectional study

Introduction

Many Malaysians with diabetes lack sufficient knowledge about diabetes selfmanagement. With the widespread adoption of smartphones, mobile health (mHealth) solutions could help empower patients with diabetes to self-manage their condition effectively. This study aimed to determine the intention of patients with diabetes to use diabetes self-management applications (DSMAs) and its associated factors in a primary care setting.

Methods

A cross-sectional study was conducted at a government health clinic in the Federal Territory of Kuala Lumpur from 1 July to 30 September 2019. We recruited 723 patients with diabetes using systematic random sampling. A validated self-administered questionnaire was used to evaluate patients' intention to use DSMAs and its associated factors were determined via multiple logistic regression.

Results

Among 719/723 patients with diabetes included in the analysis, 49.9% intended to use DSMAs. Those who had a household income of >RM 6000 (adjusted odds ratio [AOR] = 10.652, 95% confidence interval [CI] = 1.709-66.398, P<0.011), agreed (AOR=8.959, 95% CI=3.327- 24.128, P<0.001) or neutrally agreed (A0R=3.403, 95% CI= 1.188-9.749, P=0.023) with the perceived usefulness of DSMAs, did not have resistance to change (A0R=2.458, 95% CI= 1.2934.672, P=0.006) and had a facilitating condition (A0R=9.454, 95% CI=2.718-32.881, P<0.001) had higher odds of intending to use DSMAs than their counterparts.

Conclusion

Nearly half of patients with diabetes intend to use DSMAs, indicating the potential of DSMAs as alternative tools for assisting in diabetes self-management. Education focusing on the usefulness of DSMAs and exploring facilitating conditions with patients can help increase the intention of patients to use DSMAs.

Global, Regional, and National Burden of Ischemic Heart Disease Attributable to 25 Risk Factors and Their Summary Exposure Value Across 204 Countries With Different Socio-Demographic Index Levels, 1990-2021: A Systematic Fixed-Effects Analysis and Comparative Study

Background

A systematic relational assessment of the global, regional, and national Ischemic heart disease (IHD) burden and its attributable risk factors is essential for developing more targeted prevention and intervention strategies.

Methods

The GBD 2021 comparative risk assessment framework was employed to evaluate stroke burden attributable to environmental, behavioral, metabolic, and dietary risk factors, and a total of 25 risk factors were included. Specifically, we used the joinpoint regression model, decomposition analysis, and systematic fixed-effects analysis to reveal the global, regional, and national burden of IHD attributable to these 25 risk factors and their exposure value across 204 countries and territories with different socio-demographic index (SDI) levels from different perspectives.

Results

Joinpoint regression revealed similar trends in summary exposure value (SEV) and attributable burdens for 25 IHD risk factors. From 1990 to 2021, SEV rankings increased for 12/25 risk factors, decreased for 10/25, and remained unchanged for 3/25. Decomposition analysis indicated that from 1990 to 2021, low SDI countries experienced the most significant increase in IHD burden attributable to 25 risk factors due to population growth, while upper-middle and high SDI countries were most affected by population aging, and high SDI countries demonstrated the greatest reduction in IHD burden attributed to epidemiological changes. Panel data analysis elucidated the impact of SEV, SDI, and quality-of-care index (QCI) on attributable IHD burden.

Conclusion

This study emphasizing the critical role of risk factor control. Tailored interventions and exploration of country-specific factors are crucial for effectively reducing the global IHD burden.

Risk of depression and dementia among individuals treated with sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists

PURPOSE OF THE REVIEW

To review whether sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists decrease the risk of depression, suicidal ideation and cognitive impairment in later life.

RECENT FINDINGS

The results of studies using information derived from large registries and administrative health datasets suggest that GLP-1 receptor agonists (RAs) increase the risk of suicidality, although findings have been inconsistent. One nested-case control study reported that SGLT2i decreases the risk of depression among adults with diabetes, and findings from a small trial of the SGLT2i empagliflozin provided supportive evidence. Several observational studies reported that SGLT2i and GLP-1 RAs decrease dementia risk, with a target trial finding greater cognitive benefit associated with the use of GLP-1 RAs compared with other medicines commonly used to manage diabetes.

SUMMARY

Recent results from large observational studies suggest that SGLT2i and GLP-1 RA may decrease the risk of cognitive impairment in later life. The effects of these medicines on mood have not been as well explored, but there are concerns about the potential increased risk of suicidality among GLP-1 RA users. Prescription bias could explain some of these associations, so that robust trial evidence is now needed to confirm or dismiss the reported findings.

Gastrointestinal adverse events associated with GLP-1 receptor agonists in metabolic dysfunction-associated steatotic liver disease (MASLD): a systematic review and meta-analysis

Background

Metabolic dysfunction-associated steatotic liver disease, a prevalent chronic liver condition, can cause severe complications like hepatitis, cirrhosis, and hepatocellular carcinoma. In recent years, glucagon-like peptide-1 receptor agonists (GLP - 1RA) have shown unique therapeutic advantages and may become a preferred treatment for it. This meta-analysis aims to systematically examine GLP-1RA associated adverse events, providing a basis for guiding patient clinical management.

Methods

We conducted a search for randomized controlled trials (RCTs) investigating the therapeutic effects of GLP-1RA in the treatment of metabolic dysfunction-associated steatotic liver disease across four databases: PubMed, Embase, Web of Science, and Cochrane Library. The search period extended from the inception of each database until December 2023. Information pertaining to various adverse events was collected as outcome measures. Statistical analysis of the results and assessment of bias risk were conducted utilizing Review Manager (version 5.4.1) software.

Results

An analysis of 10 studies encompassing 960 participants revealed a significantly higher overall incidence of adverse events in the GLP-1RA group compared to the control group (OR: 2.40 [1.10, 5.26], P = 0.03). Subgroup analysis based on treatment duration demonstrated a higher rate of adverse events in the GLP-1RA group during follow-ups of less than 30 weeks (P = 0.0005, OR: 3.58 [1.75, 7.32]), but no statistical difference was observed between the two groups in follow-ups exceeding 30 weeks. There was no statistically significant difference between the two groups in adverse events leading to discontinuation (P = 0.29, OR: 1.47 [0.72, 2.98]). However, a notable difference was observed in gastrointestinal adverse events (P < 0.00001, OR: 4.83 [3.36, 6.95]).

Conclusion

GLP-1RA exhibits an overall higher incidence of adverse events in the treatment of metabolic dysfunction-associated steatotic liver disease, particularly in the gastrointestinal domain. Short-term use of GLP-1RA may be associated with a greater occurrence of adverse events, underscoring the importance of educating patients on preventive measures and establishing tolerance. However, there was no statistically significant difference between the two groups in severe adverse events and adverse events leading to discontinuation, confirming the safety profile of GLP-1RA application.

Exploring the perceptions of Chinese adults toward overweight and obesity: A systematic literature review

INTRODUCTION

The prevalence of obesity among the Chinese population has increased more than three-fold over the last twenty years. It is crucial to understand Chinese people's perceptions toward obesity to inform effective weight management initiatives. This bilingual systematic review aimed to synthesize the existing literature regarding the perceptions of Chinese adults toward overweight and obesity and provide insight on methodological implications and future research directions.

METHOD

Six databases were searched from inception to 8th January 2025. Studies were included if they were published in English or Chinese, investigated perceptions toward overweight and obesity, and focused on Chinese adults living in or outside of Mainland China. Thematic synthesis was employed for data analysis.

RESULTS

Fifty-three studies (24 in English, 29 in Chinese) were included, involving 83,688 participants. Three themes were identified; (1) Chinese adults connected obesity with appearance more than with health, (2) Chinese adults lacked practical knowledge to manage obesity, and (3) living with obesity was perceived as a solitary journey.

CONCLUSION

Most studies were conducted on Chinese people within the healthy weight range, who predominantly focused on appearance-oriented weight perception. There was a strong motivation for weight control, but a lack of practical weight loss strategies among Chinese adults.

PRACTITIONER APPLICATIONS

The lack of practical weight management knowledge and weight loss failures lead to low self-efficacy, which may be mistaken as low motivation for weight management among Chinese adults. However, Chinese adults generally have the motivation to control their weight. It is important to empower Chinese people living with overweight or obesity with practical skills and increase self-efficacy through a multidisciplinary and affordable approach. The psychological burden caused by obesity stigma and the influence of Chinese culture makes the weight management journey lonely and challenging for Chinese adults living with overweight and obesity. Practitioners may need to openly address these issues and help reduce the mental burden toward more effective weight loss interventions.

Obesity and Glucagon-Like Peptide-1 Receptor Agonists

This Viewpoint discusses factors associated with the prevalence of obesity worldwide and whether the novel glucagon-like peptide-1 receptor agonists (GLP-1) can help unlock a health systems response to the obesity pandemic.

Effect of Exercise and Nutrition Intervention for Older Adults with Impaired Physical Function with Preserved Muscle Mass (Functional Sarcopenia): A Randomized Controlled Trial

Background

Functional sarcopenia is characterized by decreased physical performance and grip strength despite preserved muscle mass. The effectiveness of a program combining exercise and nutritional support-known interventions for individuals with low muscle mass-was evaluated for its impact on older adults with functional sarcopenia.

Methods

An unblinded, parallel-group randomized controlled trial was conducted in a public medical center in a rural Korean community. Eligible older adults with functional sarcopenia were randomized into either the intervention group, receiving a 12-week program of group exercises and nutritional support, or the control group, receiving education on lifestyle management. Outcomes measured included changes in gait speed, grip strength, physical performance, and quality of life indices.

Results

The study enrolled 42 participants, with 21 allocated to each group. Compared with the control group, the intervention group showed significant improvements in the primary outcome of gait speed (mean change (m/s) 0.24 vs 0.00, p<0.001) and secondary outcomes, such as Short Physical Performance Battery scores, grip strength, and quality of life. No significant adverse events were reported.

Conclusion

The 12-week exercise and nutritional intervention significantly enhanced physical performance, grip strength, and quality of life among community-dwelling older adults with functional sarcopenia. This suggests that strategies commonly recommended for sarcopenia, including exercise and nutritional support, are also beneficial for individuals with functional sarcopenia, indicating the potential for broader application of such interventions.

Comparison of Weight Loss and Improvement in Metabolic Comorbidities Between Endoscopic Gastroplasty and Lifestyle Modifications: A Meta-analysis

BACKGROUND

Endoscopic gastroplasty (EG) is a less invasive method for managing obesity compared with bariatric surgery. However, evidence on the use of EG is still scarce. This study aims to review existing evidence comparing EG with lifestyle modifications (LM) in terms of weight loss and improvement in metabolic syndrome.

MATERIALS AND METHODS

A systematic search was performed on PubMed, Embase, and the Cochrane Library from inception to August 2023. Exclusion criteria were patients who received concomitant pharmacological therapy for weight loss, the use of other endoscopic interventions apart from EG, and patients with prior bariatric surgery. Based on the heterogeneity of included studies, meta-analysis was performed using either a fixed-effect model or a random-effect model.

RESULTS

There were 5 studies (4 RCTs and 1 retrospective study) with 1007 patients included in the pooled analysis. Only a minority were males (n=199, 19.8%), and only 1 study included a Sham procedure in the LM group. Six-month percentage total body weight loss (%TBWL) (n=3 studies, MD: 6.34, 95% CI: 2.89, 9.78, P<0.01) and 12-month %TBWL (n=4 studies, MD: 6.43, 95% CI: 2.62, 10.25, P<0.01) were significantly higher in EG compared with LM. Patients in the EG group also had significant improvement in control of diabetes mellitus (n=2 studies, OR: 29.10, 95% CI: 5.84, 145.08) and hypertension (n=2 studies, OR: 2.35, 95% CI: 1.18, 4.70) compared with LM. Incidence of serious adverse events ranged from 2% to 5%.

CONCLUSION

EG is effective for weight loss and improvement in metabolic comorbidities compared with LM alone but is suboptimal based on the Food and Drug Administration thresholds.

Medical Management of Obesity: Current Trends and Future Perspectives

Obesity and overweight have become increasingly significant conditions, affecting more than 70% of the adult population in the United States. These conditions are caused by a combination of factors, including genetic, behavioral, environmental, and medical influences. Obesity is a major risk factor for cardiovascular and metabolic diseases. A comprehensive treatment plan for individuals with obesity must recognize the chronic nature of the condition and offer strategies for weight reduction and long-term cardiometabolic benefits. Over the past several decades, multiple therapeutic options have been implemented to address weight loss, appetite regulation, and caloric expenditure, with the goal of reducing the burden of obesity and improving cardiovascular outcomes. Pharmacological treatment of obesity has focused primarily on the central regulation of appetite and food intake behavior. The introduction of incretin agonists for obesity treatment has ushered in a new era of cardiometabolic health, with a multitargeted mechanism that achieves weight loss, glycemic control, decreased cardiovascular mortality, and other metabolic benefits. This review explores the current pharmacological options and the future of obesity treatment.

Iron Status Correlates Strongly to Insulin Resistance Among US Adults: A Nationwide Population-Based Study

CONTEXT

Evidence on the link between iron status markers and insulin resistance (IR) is limited.

OBJECTIVE

We aimed to explore the relationship between iron status and IR among US adults.

METHODS

This study involved 2993 participants from the National Health and Nutrition Examination Survey (NHANES) 2003-2006, 2017-2020. IR is characterized by a homeostatic model assessment (HOMA)-IR value of ≥2.5. Weighted linear and multivariable logistic regression analyses were used to examine the linear relationships between iron status and IR. Furthermore, restricted cubic splines (RCS) were used to identify the nonlinear dose-response associations. Stratified analyses by age, sex, body mass index, and physical activity were also performed. Last, a receiver operating characteristic (ROC) curve was used to evaluate the predictive value of iron status in IR.

RESULTS

In weighted linear analyses, serum iron (SI) exhibited a negative correlation with HOMA-IR (β -0.03, 95% CI -0.05, -0.01, P = .01). In weighted multivariate logistic analyses, iron intake and the serum transferrin receptor (sTfR) were positively correlated with IR (OR 1.02, 95% CI 1.00-1.04, P = .04; OR 1.07, 95% CI 1.02-1.13, P = .01). Also, SI and transferrin saturation (TSAT) were negatively correlated with IR (OR 0.96, 95% CI 0.94-0.98, P < .0001; OR 0.98, 95% CI 0.97-0.99, P < .001) after adjusting for confounding factors. RCS depicted a nonlinear dose-response relationship between sTfR and TSAT and IR. This correlation remained consistent across various population subgroups. The ROC curve showed that TSAT performed better than iron intake, SI and sTfR in ROC analyses for IR prediction.

CONCLUSION

All biomarkers demonstrated significantly lower risk of IR with increasing iron levels, which will contribute to a more comprehensive and in-depth understanding of the relationship between the 2 and provide a solid foundation for future exploration of the mechanisms underlying their relationship.

Efficacy of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists on proteinuria and weight in a diabetes cohort

BACKGROUND

With accumulating evidence showing a benefit in the renal and cardiovascular systems, diabetes guidelines recommend that patients with diabetes and chronic kidney disease (CKD) be treated with sodium-glucose cotransporter-2 inhibitor (SGLT2i) and/or glucagon like peptide-1 receptor agonists (GLP-1RAs) for renal protection. The real-world efficacy of the two medications on the urinary albumin-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) remains to be explored.

AIM

To evaluate the SGLT2i and GLP-1RA application rates and UACR alterations after intervention in a real-world cohort of patients with diabetes.

METHODS

A cohort of 5482 patients with type 2 diabetes were enrolled and followed up at the Integrated Care Clinic for Diabetes of Peking University First Hospital for at least 6 months. Propensity score matching was performed, and patients who were not recommended for GLP-1RA or SGLT2i with comparable sex categories and ages were assigned to the control group at a 1:2 ratio. Blood glucose, body weight, UACR and eGFR were evaluated after 6 months of treatment in real-world clinical practice.

RESULTS

A total of 139 (2.54%) patients started GLP-1RA, and 387 (7.06%) received SGLT2i. After 6 months, the variations in fasting blood glucose, prandial blood glucose, and glycosylated hemoglobin between the GLP-1RA group and the SGLT2i and control groups were not significantly different. UACR showed a tendency toward a greater reduction compared with the control group, although this difference was not statistically significant (GLP-1RA vs control, -2.20 vs 30.16 mg/g, P = 0.812; SGLT2i vs control, -20.61 vs 12.01 mg/g, P = 0.327); eGFR alteration also showed no significant differences. Significant weight loss was observed in the GLP-1RA group compared with the control group (GLP-1RA vs control, -0.90 vs 0.27 kg, P < 0.001), as well as in the SGLT2i group (SGLT2i vs control, -0.59 vs -0.03 kg, P = 0.010).

CONCLUSION

Compared with patients who received other glucose-lowering drugs, patients receiving SGLT2i or GLP-1RAs presented significant weight loss, a decreasing trend in UACR and comparable glucose-lowering effects in real-world settings.

Uncovering the role of prokineticin pathway on Epicardial Adipose Tissue (EAT) development and EAT-associated cardiomyopathy

Epicardial adipose tissue (EAT), a unique fat depot surrounding the heart, plays a multifaceted role in glucose and lipid metabolism, thermogenesis, and the secretion of bioactive molecules that influence cardiac structure and function. Its proximity to the myocardium allows it to contribute directly to CVDs, including coronary artery disease, arrhythmias, and heart failure. In particular, excessive EAT has emerged as a significant factor in heart failure with preserved ejection fraction (HFpEF), the most common form of heart failure, especially in individuals with obesity and diabetes. Traditional metrics like body mass index (BMI) fail to capture the complexities of visceral fat, as patients with similar BMIs can exhibit varying CVD risks. EAT accumulation induces mechanical stress and fosters a pro-inflammatory and fibrotic environment, driving cardiac remodeling and dysfunction. Pharmacological modulation of EAT has shown promise in delivering cardiometabolic benefits. Recent advancements in diabetes therapies, such as SGLT2 inhibitors and GLP-1 receptor agonists, and antilipidemic drugs have demonstrated their potential in reducing pro-inflammatory cytokine production and improving glucose regulation, which directly influences EAT. These discoveries suggest that EAT could be a significant therapeutic target, though further investigation is necessary to elucidate its role in HFpEF and other CVDs. Recent advances have identified the prokineticin/PKR1 signaling pathway as pivotal in EAT development and remodeling. This pathway regulates epicardial progenitor cells (EPDCs), promoting angiogenesis while reducing EAT accumulation and metabolic stress on the heart, particularly under high-calorie conditions. Prokineticin, acting through its receptor PKR1, limits visceral adipose tissue growth, enhances insulin sensitivity, and offers cardioprotection by reducing oxidative stress and activating cellular survival pathways. In this review, we provide a comprehensive analysis of EAT's role in CVDs, explore novel therapeutic strategies targeting EAT, and highlight the potential of prokineticin signaling as a promising treatment for HFpEF, obesity, and diabetes.

The protective effect of sodium-glucose cotransporter-2 inhibitor on left ventricular global longitudinal strain in patients with type 2 diabetes mellitus according to disease duration

Our study aimed to elucidate the impact of sodium-glucose cotransporter-2 inhibitor on left ventricular systolic function using global longitudinal strain in type 2 diabetes mellitus patients and to assess its protective effect depending on disease duration. Type 2 diabetes mellitus patients treated at our institute were included. According to whether sodium-glucose cotransporter-2 inhibitor was used in drug treatment, the patients were divided into SGLT2i group and control group, and propensity score matching was performed. For subgroup analysis, patients were further classified based on disease duration (1-5 years, 5-10 years, and 10-20 years). A total of 256 patients with type 2 diabetes mellitus were enrolled. Significantly better global longitudinal strain results were observed at the 6-month follow-up in the SGLT2i group than those of the control group and its baseline (p < 0.001). A significantly lower proportion of subclinical cardiac dysfunction was observed in the SGLT2i group (p < 0.001). Significantly greater global longitudinal strains were observed in the SGLT2i subgroups compared with control subgroups (p all < 0.05). Furthermore, sodium-glucose cotransporter-2 inhibitor use and epicardial adipose tissue thickness change were independently associated with global longitudinal strain change according to multivariate analysis. Sodium-glucose cotransporter-2 inhibitor significantly improved left ventricular function in type 2 diabetes mellitus patients without cardiovascular complications, regardless of disease duration, with more prominent outcomes observed in patients with early-stage disease.

Differences in the Prevalence and Clinical Correlates Between Early-Onset and Late-Onset Major Depressive Disorder Patients with Comorbid Abnormal Lipid Metabolism

BACKGROUND AND OBJECTIVES

Growing evidence suggested that abnormal lipid metabolism (ALM) was associated with an increased severity of depressive symptoms, but no previous studies have examined the differences in comorbid ALM in major depressive disorder (MDD) patients of different ages of onset. We aim to compare the differences in the prevalence and clinical correlates of ALM between early-onset and late-onset patients with first-episode and drug-naive (FEDN) MDD patients.

METHODS

Using a cross-sectional design, we recruited a total of 1718 FEDN MDD outpatients in this study. We used the 17-item Hamilton Rating Scale for Depression (HAMD-17), The Hamilton Anxiety Rating Scale (HAMA), the Positive and Negative Syndrome Scale (PANSS) positive subscale, and Clinical Global Impression-Severity Scale (CGI-S) to assess their depression, anxiety, and psychotic symptoms and clinical severity, respectively.

RESULTS

There were 349 patients (20.3%) in the early-onset subgroup and 1369 (79.7%) in the late-onset subgroup. In this study, 65.1% (1188/1718) of patients were diagnosed with ALM. The prevalence of ALM in the late-onset group (81.5%, 1116/1369) was significantly higher than that in the early-onset group (20.6%, 72/349) (p = 0.36, OR = 1.147, 95%CI = 0.855-1.537). The HAMD total score (OR = 1.34, 95% CI = 1.18-1.53, p < 0.001) was the only risk factor for ALM in early-onset MDD patients. In late-onset MDD patients, the HAMD total score (OR = 1.19, 95% CI = 1.11-1.28, p < 0.001), TSH (OR = 1.25, 95% CI = 1.16-1.36, p < 0.001), CGI (OR = 1.7, 95% CI = 1.31-2.19, p < 0.001), and anxiety (OR = 2.22, 95% CI = 1.23-4.02, p = 0.008) were risk factors for ALM.

CONCLUSION AND SCIENTIFIC SIGNIFICANCE

Our results suggest that there are significant differences in the prevalence and clinical factors of comorbid ALM between early-onset and late-onset FEND MDD patients.

The new definition of metabolic syndrome including hyperuricemia improves its prognostic value: results from NHANES database

BACKGROUND

Metabolic syndrome (MetS) is a significant global health issue that is strongly associated with an increased risk of cardiovascular disease (CVD). While MetS was initially proposed to identify more high-risk individuals and facilitate early management, hyperuricemia has not yet been included in its definition, despite its strong association with MetS. This study aims to explore the prognostic value of incorporating hyperuricemia into the definition of MetS.

METHODS

Data derived from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2018 were analyzed. The old version of MetS (MetSold) aligned with NCEP-ATP III criteria, whereas the new version of MetS (MetSnew) included hyperuricemia as a sixth criterion. Baseline characteristics were compared between participants with and without MetS, and outcomes were assessed by multivariate analyses.

RESULTS

Among the 36,363 participants analyzed, 12,594 (34.6%) and 14,137 (38.9%) met MetSold and MetSnew criteriarespectively. Compared to MetSold, MetSnew identified additional 1534(4.24%) participants at metabolic risk. Both MetSold and MetSnew were significantly associated with long-term all-cause and CVD mortality (all P < 0.001). Furthermore, the additional participants identified by MetSnew exhibited a similar risk of all-cause and CVD mortality as those meeting MetSold criteria. MetSnew demonstrated enhanced identification and reclassification abilities compared to MetSold, as evidenced by improvement in C-index, NRI and IDI.

CONCLUSIONS

The inclusion of hyperuricemia in the MetS criteria could identify a larger proportion of individuals at metabolic risk, thereby facilitating early management to prevent long-term adverse events.

Clinicians' experience with infographic summaries from the BMJ Rapid Recommendations: a qualitative user-testing study among residents and interns at a large teaching hospital in Switzerland

OBJECTIVE

Clinicians need trustworthy clinical practice guidelines to succeed with evidence-based diagnosis and treatment at the bedside. The BMJ Rapid Recommendations explore innovative ways to enhance dissemination and uptake, including multilayered interactive infographics linked to a digitally structured authoring and publication platform (the MAGICapp). We aimed to assess user experiences of physicians in training in various specialties when they interact with these infographics.

DESIGN

We conducted a qualitative user-testing study to assess user experience of a convenience sample of physicians in training. User testing was carried out through guided think-aloud sessions. We assessed six facets of user experience using a revised version of Morville's framework: usefulness, understandability, usability, credibility, desirability and identification.

SETTING

Setting include Geneva's University Hospital, a large teaching hospital in Switzerland.

PARTICIPANTS

Participants include a convenience sample of residents and interns without restriction regarding medical field or division of care.

RESULTS

Most users reported a positive experience. The infographics were understandable and useful to rapidly grasp the key elements of the recommendation, its rationale and supporting evidence, in a credible way. Some users felt intimidated by numbers or the amount of information, although they perceived there could be a learning curve while using generic formats. Plain language summaries helped complement the visuals but could be further highlighted. Despite their generally positive experience, several users had limited understanding of key GRADE (Grading of Recommendations Assessment, Development and Evaluation) domains of the quality of evidence and remained uncertain by the implication of weak or conditional recommendations.

CONCLUSION

Our study allowed to identify several aspects of guideline formats that improve their understandability and usefulness. Guideline organisations can use our findings to adapt their presentation format to enhance their dissemination and uptake in clinical practice. Avenues for research include the interplay between infographics and the digital authoring platform, multiple comparisons and living guidelines.

Red Meat Consumption and Hypertension: An Updated Review

PURPOSE OF REVIEW

Hypertension (HTN) is a major risk factor for cardiovascular diseases (CVD). The global prevalence of HTN and related CVD mortality continues to rise. The development of HTN is influenced by genetic predisposition and modifiable risk factors, including diet. One area of ongoing debate is the relationship between red meat consumption and risk of HTN.

RECENT FINDINGS

Processed red meat has become increasingly implicated in the pathogenesis and morbidity of HTN, though randomized control trials comparing HTN-related outcomes associated with red meat subtypes have yielded heterogenous results. This review summarizes the existing relevant literature and highlights the methodological challenges that complicate definitive conclusions, with a focus on processed versus unprocessed red meat consumption and HTN. It explores pathophysiologic mechanisms contributing to this relationship and reviews practical, evidence-based dietary guidelines that address red meat consumption to mitigate the risk of adverse HTN-related CVD outcomes.

Macrophages Unmasked: Their Pivotal Role in Driving Atherosclerosis in Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease that significantly increases the risk of cardiovascular diseases, particularly atherosclerosis (AS). Understanding the shared pathogenic mechanisms underlying SLE and AS is crucial for developing effective therapeutic strategies. Macrophages, as pivotal immune cells, play a critical role in the initiation and progression of atherosclerotic plaques within the context of SLE. This review delves into the molecular and cellular mechanisms governing macrophage activation and differentiation in response to SLE-related inflammatory mediators, highlighting their roles in lipid metabolism, plaque stability, and immune regulation. Additionally, we discussed the current treatment modalities for SLE and their impact on macrophage functionality, exploring these effects for atherosclerotic progression. By elucidating the intricate relationship between macrophages, SLE pathophysiology, and AS progression, this review underscores the need for a multidisciplinary approach in managing SLE and its cardiovascular complications, aiming to improve patient survival and quality of life through tailored therapeutic interventions addressing both autoimmune and cardiovascular pathologies.

A Hypothesis That Glucagon-like Peptide-1 Receptor Agonists Exert Immediate and Multifaceted Effects by Activating Adenosine Monophosphate-Activate Protein Kinase (AMPK)

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) reduce bodyweight and blood glucose. Extensive evidence from randomized controlled trials has indicated that GLP-1RAs have benefits well beyond weight loss and glucose control, extending from reductions in cardiovascular mortality to reductions in prostate cancer risk. Notably, some benefits of GLP-1RAs for the cardiovascular-kidney-metabolic (CKM) system arise before weight loss occurs for reasons that are not entirely clear but are key to patient care and drug development. Here, we hypothesize that GLP-1RAs act by inducing calorie restriction and by activating adenosine monophosphate-activated protein kinase (AMPK), which not only provides an explanation for the unique effectiveness of GLP-1RAs but also indicates a common mechanism shared by effective CKM therapies, including salicylates, metformin, statins, healthy diet, and physical activity. Whether AMPK activation is obligatory for effective CKM therapies should be considered. As such, we propose a mechanism of action for GLP-1RAs and explain how it provides an overarching framework for identifying means of preventing and treating cardiovascular, kidney, metabolic and related diseases, as well as informing the complementary question as to the components of a healthy lifestyle.

Potential pharmacological effect of Quercetin Phytosome™ in the management of hyperuricemia: results from real-life clinical studies

Background

Hyperuricemia is associated with several metabolic and cardiovascular disorders, and traditional treatments, such as xanthine oxidase (XO) inhibitors, often have limitations, such as severe hypersensitivity reactions or ineffectiveness in achieving target serum urate levels in some patients. Quercetin, a naturally occurring flavonoid, has shown potential as a hypouricemic agent through XO inhibition.

Objective

This study aims to evaluate the potential hypouricemic effect of Quercetin Phytosome™ (QP) supplementation across three cohort studies involving healthy adults with various metabolic health profiles, exploring its potential as a safe, effective intervention for hyperuricemia.

Methods

Clinical data collected in various clinics in Italy between September 2021 and April 2024 under real-life clinical settings from three distinct cohort studies, were analyzed. Cohort 1 consisted of 164 healthy participants (87 QP-treated, 77 probiotic Streptococcus salivarius (S. salivarius) K12-treated) who were monitored for 90 days. Cohort 2 included 22 mildly hyperuricemic adults with metabolic disorders receiving QP, while Cohort 3 comprised 64 obese adults with hypercholesterolemia, further divided into moderately hyperuricemic QP-treated group (n = 20), a moderately hyperuricemic Berberine Phytosome™ and monacolins (BM)-treated group (n = 22), and a normouricemic BM-treated group (n = 22). QP was administered at 400 mg of quercetin daily in all cohorts. Primary endpoints were reductions in serum uric acid levels, while secondary outcomes included effects on lipid profile, glycemia, liver enzymes, and treatment tolerability.

Results

In Cohort 1, QP significantly reduced uric acid levels by 15.2% in males and 13.8% in females, with no significant changes observed in the probiotic group. Cohort 2 showed a significant 13.1% reduction in uric acid (p < 0.01) and a concurrent 10.2% reduction in triglycerides (p < 0.05). In Cohort 3, QP led to a 13.7% decrease in uric acid and a 20.8% reduction in triglycerides (p < 0.01), with no significant uric acid changes in the BM-treated group. QP was well tolerated across all cohorts, with minimal, transient side effects.

Conclusion

QP supplementation demonstrates a significant hypouricemic effect. Additionally, triglyceride-lowering benefits were evident, particularly in metabolically compromised individuals (Cohorts 2 and 3), where these effects were statistically significant. With high tolerability, these findings highlight Quercetin Phytosome™'s potential as a safe adjunctive therapy for hyperuricemia management, meriting further investigation in larger, randomized trials to confirm its efficacy and safety.

A single-centre, retrospective study on the impact of omitting preoperative antibiotic prophylaxis on wound infections in minor orthopedic implant removals

BACKGROUND

The use of preoperative antibiotic prophylaxis (POAP) in elective implant removal (IR) is controversial due to a lack of evidence-based recommendations. First-generation cephalosporins, which are commonly used in orthopedic IR, are believed to reduce wound infection risks. However, the potential for serious side effects had raised concerns about their necessity. This study was intended to evaluate whether omitting POAP in small IR increases the risk of wound infections.

METHODS

This retrospective, single-centre cohort study was conducted at a level I trauma centre in Switzerland, including patients who underwent IR between January 1, 2016, and December 31, 2021. The IR procedures involved the upper extremities (UEs), such as the clavicle, olecranon, radius and ulna, as well as the lower extremities (LEs), such as the patella, tibia, fibula, (bi)malleolar and foot. Postoperative follow-up included clinical and radiological evaluations 6 weeks after surgery. The outcomes assessed were deep wound infections, wound healing complications, refractures, persistent pain, bleeding, neurovascular injuries and muscle hernias.

RESULTS

Of the 273 patients (mean age: 42.1 ± 14.5; 44% female), 117 (42.9%) received POAP. In the LE group (n = 141), 51.1% received POAP; in the UE group (n = 132), 34.1% received POAP. Eleven (4.0%) wound-healing disorders were documented, with five (4.3%) in the POAP group and six (3.8%) in the non-POAP group (p = 1). No deep wound infections were observed.

CONCLUSION

Withholding POAP in elective IR procedures does not significantly increase wound infection rates, suggesting it may be unnecessary in uncomplicated cases.

Quantitative Comparison of Glucagon-Like Peptide-1 Receptor Agonists on Weight Loss in Adults: A Systematic Review and Model-Based Meta-Analysis

The objective of this study is to quantitatively compare the weight loss effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in adult patients with no diabetes and type 2 diabetes (T2D). PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Embase have been used as data sources from database inception to January 6, 2024. A total of 137 trials, encompassing 310 treatment arms, 17 GLP-1RAs, and 56,683 patients, were included in the analysis. The included trials were divided into three groups based on the characteristics of the populations: nondiabetic overweight or obesity group (NDOOG), type 2 diabetes Caucasian group (T2DCG), and type 2 diabetes Asian group (T2DAG). The effects of covariates were further evaluated, patients with a higher baseline body weight tend to have better weight loss outcomes, and patients with a higher baseline glycated hemoglobin (HbA1c) tend to achieve better blood sugar control. Five mathematical models were subjected to longitudinal analysis. In terms of Δ body weight, retatrutide (12 mg qw) was the most effective treatment (mean difference = -26.56% [95% confidence interval: -43.89% to -3.01%]). Tirzepatide (15 mg qw) demonstrated good weight loss ability in all three ΔBW models, ΔBW-NDOOG (-22.76% [-26.45% to -18.50%]), ΔBW-T2DCG (-11.09% [-12.39% to -9.44%])), and ΔBW-T2DAG (-4.97% [-5.84% to -4.12%]). In the aspect of ΔHbA1c, tirzepatide (10 mg qw) and oral orforglipron (10 mg qd) were the most effective drug, respectively. GLP-1RAs demonstrated effective weight management in both nondiabetic and T2D populations. Retatrutide achieved the most pronounced weight reduction, followed by tirzepatide. GLP-1RAs also significantly improved glycemic control for patients with T2D, with tirzepatide performing the best for glycemic control.

Postoperative sepsis and its sequential impact on dementia

BACKGROUND

Postoperative sepsis is a severe complication associated with increased mortality and potential long-term cognitive decline, including dementia. However, the relationship between postoperative sepsis and dementia remains poorly understood.

METHODS

This retrospective cohort study used data from the National Database in Taiwan, covering the period from January 1, 2005, to December 31, 2022. The index period for surgeries was set between January 1, 2008, and December 31, 2013, allowing the identification of patients without prior dementia. A landmark period of 12 months following surgery was defined to capture the number of postoperative sepsis events, which were then analyzed for their impact on dementia risk. After 1:4 propensity score matching (PSM), dementia and mortality were evaluated using Cox proportional hazards and Fine-Gray competing risk models.

RESULTS

Following PSM, 778 patients were in the postoperative sepsis group and 3,112 in the non-postoperative sepsis group. Dementia incidence was higher in the postoperative sepsis group (26%) compared to the non- postoperative sepsis group (13.6%), with a hazard ratio (HR) of 1.25 (95% CI, 1.03-1.52). A dose-response relationship was observed, with dementia rates of 24.5% for one postoperative sepsis event and 34.9% for two or more events, the latter showing an HR of 1.77 (95% CI, 1.17-2.66). Mortality was also elevated in the postoperative sepsis group (40.5% vs. 31.6%; HR 1.45, 95% CI, 1.28-1.65).

CONCLUSIONS

Postoperative sepsis is significantly associated with increased dementia risk in a dose-dependent manner. These findings highlight the importance of enhancing perioperative infection control to reduce both immediate and long-term cognitive complications.

Effects of 12-month physical and cognitive training on sarcopenia determinants in older adults: a subgroup analysis of a randomised clinical trial

BACKGROUND

Low physical activity is a major risk for sarcopenia. Whether training according to physical activity guidelines accompanied with cognitive training is effective on sarcopenia, remains unclear.

AIMS

We investigated whether the effects of 12-month physical and cognitive training (PTCT) and physical training (PT) on grip and knee extension strength, muscle mass, and walking speed differed between older adults with and without sarcopenia.

METHODS

Community-dwelling older adults (N = 314, mean age 74.5 ± 3.8 years, 60% women) who did not meet physical activity guidelines were randomized to PTCT and PT groups. PT for both groups included supervised and home-based multicomponent physical training. Cognitive training (CT) included computer-based exercises for executive functioning. Sarcopenia was determined according to the European Working Group on Sarcopenia in Older People 2019 criteria. Generalized estimation equation analysis were conducted.

RESULTS

Compared to PT, PTCT had no additive effect on strength, muscle mass, or walking speed in participants with or without sarcopenia. In pooled data (PT + PTCT) change in the grip strength was greater in sarcopenia (n = 49) group compared to non-sarcopenia (n = 264) group (interaction, p =.014). Both groups improved knee extension strength, and walking speed, but no statistically significant difference between the groups were observed. Muscle mass did not change in either group.

CONCLUSION

Physical training according to physical activity recommendations improves muscle strength, walking speed, and maintains muscle mass in sarcopenia. Additional cognitive training had no benefits on these outcomes.

Diabetic Ketoacidosis and the Use of New Hypoglycemic Groups: Real-World Evidence Utilizing the Food and Drug Administration Adverse Event Reporting System

Background: Diabetic ketoacidosis (DKA), a life-threatening complication, can occur in individuals with type 2 diabetes during illness, stress, or medication use. This study examines DKA signals in type 2 diabetes, focusing on sodium-glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and dipeptidyl-peptidase-4 (DPP-4) inhibitors. Methods: DKA reports from Q1 2019 to Q3 2024 were retrieved from the FDA Adverse Event Reporting System (FAERS). Associations between primary exposure and outcomes were ascertained using four key metrics: Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Empirical Bayes Geometric Mean (EBGM), and Information Component (IC). Results: SGLT2 inhibitors exhibited the higher DKA risk in 2019-2021 (ROR: 314.86 [95% CI 301.76-328.53], PRR of 245.69 [95% CI 235.47-256.36], IC of 6.90, and EBGM of 120), declining in 2022-2024. GLP-1 receptor agonists showed an ROR increase from 2.88 [95% CI 2.56-3.25] in 2019-2021 to 4.64 [95% CI 4.06-5.29] in 2022-2023, slightly declining to 3.95 [95% CI 3.27-4.74] in 2024. DPP-4 inhibitors exhibited a steady ROR rise from 6.81 [95% CI 5.52-8.40] in 2019-2021 to 8.57 [95% CI 6.24-11.76] in 2022-2023 and further to 11.02 [95% CI 6.71-18.10] in 2024. PRR, EBGM, and IC values followed similar trends. The age groups 41-60 and 61-91 years were the most affected, with hospitalization at its highest rate for DPP4-inhibitors in Q1-Q3 of 2024. Hospitalizations were also observed with GLP-1 receptor agonists and SGLT2 inhibitors. Life-threatening events and fatalities were also reported, with physicians contributing to most reports. Conclusions: DKA signals were observed for all three drug classes, particularly among elderly patients, highlighting the need for careful monitoring, especially during periods of illness or stress. However, the risk was higher in the SGLT2 inhibitor group than in the other groups.

Efficacy and safety of PCSK9 inhibitors, potent statins, and their combinations for reducing low-density lipoprotein cholesterol in hyperlipidemia patients: a systematic network meta-analysis

Background

The objective of this study is to assess the relative efficacy of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, such as alirocumab, evolocumab, and inclisiran, in conjunction with potent statins like atorvastatin and rosuvastatin, in patients presenting with hyperlipidemia or heightened cardiovascular risk attributable to elevated low-density lipoprotein cholesterol (LDL-C).

Methods

A systematic search was conducted across databases including PubMed, Embase, and the Cochrane Library to explore lipid-lowering therapies in hyperlipidemia from their inception to 7 November 2023. A network meta-analysis (NMA) was conducted via Stata 17 software, with two authors independently conducting the search, screening, and data abstraction.

Results

A total of 68 clinical studies involving 21,288 patients with hyperlipidemia were incorporated into the NMA. PSCK9 inhibitors and potent statins significantly reduced LDL-C levels from baseline vs. placebo regardless of background therapy. Regarding the efficacy of lipid reduction, four principal medications were evaluated: evolocumab and atorvastatin [mean standard deviation (MD) -3.41, 95% CI -4.81 to -2.00] and evolocumab with rosuvastatin (MD -3.44, 95% CI -5.10 to -1.78) vs. placebo; alirocumab combined with rosuvastatin (MD -2.91, 95% CI -3.95 to -1.88) and alirocumab with atorvastatin (MD -2.90, 95% CI -3.97 to -1.84) vs. placebo. Meanwhile, compared with placebo, evolocumab (MD -1.89, 95% CI -2.27 to -1.50), alirocumab (MD -1.83, 95% CI -2.09 to -1.57), rosuvastatin (MD -1.93, 95% CI -2.30 to -1.56), inclisiran (MD -1.68, 95% CI -2.10 to -1.27), and atorvastatin (MD -1.68, 95% CI -2.04 to -1.31) could also play a role in the treatment of LDL-C reduction. Moreover, the incidence of adverse events (AEs) was similar to that observed in the control group, which included both placebo and potent statin groups, with no significant differences identified in our study (P > 0.05).

Conclusions

The combination of PCSK9 inhibitors with robust statins like rosuvastatin and atorvastatin markedly decreases LDL-C levels in patients with hyperlipidemia when compared to placebo or monotherapy. Notably, the pairing of evolocumab and atorvastatin exhibited exceptional efficacy in this investigation. In the interim, the combination of PCSK9 inhibitors and potent statins demonstrates a notable safety profile when contrasted with the control group.

Dapagliflozin treatment alleviates fatty liver in patients with type 2 diabetes

Non-alcoholic fatty liver disease (NAFLD) is common in patients with type 2 diabetes mellitus (T2DM). The present study evaluated the effect of dapagliflozin on the liver fat content in patients with T2DM and NAFLD. The changes in biochemical data and metabolic parameters were analyzed. Clinical data of patients with T2DM and NAFLD treated by dapagliflozin were retrospectively collected between June 2022 and December 2022. A total of 35 patients, with a mean age of 45.8±2.2 years, consisting of 60.0% male patients, were included in the final analysis. After 20 weeks of dapagliflozin treatment, the parameters of diabetes improved. Plasma glucose and hemoglobin A1C levels significantly decreased (P<0.01), and insulin resistance improved. The change in liver fat content was evaluated by quantitative computed tomography, which revealed a decrease from 16.1±2.2 to 11.2±1.3% after treatment (P<0.01). Liver function (alanine aminotransferase, aspartate aminotransferase and γ-glutamyltransferase levels) also improved. Visceral and subcutaneous fat areas showed a significant decrease after treatment, and there was a more significant reduction in visceral fat area. The factors associated with liver fat content were determined by Pearson's correlation and regression analyses. Pearson's correlation analysis indicated that the post-treatment decrease in liver fat content was positively correlated with the change in body weight (r=0.642, P=0.033), index of homeostasis model assessment-insulin resistance (r=0.670, P=0.048), triglycerides (r=0.627, P=0.039), high sensitivity C-reactive protein (r=0.608, P=0.047) and interleukin (IL)-6 (r=0.604, P=0.049). Linear regression analysis revealed that body weight (β=0.416, P=0.001), IL-6 (β=0.284, P=0.009), triglycerides (β=0.262, P=0.011) and total cholesterol (β=0.388, P=0.001) were independent factors related to liver fat content. In conclusion, dapagliflozin can reduce liver fat in patients with T2DM and NAFLD. The reduction in liver fat is associated with improvement of metabolic parameters and inflammatory cytokines.

Senescent cells as a target for anti-aging interventions: From senolytics to immune therapies

Aging and age-related diseases are major drivers of multimorbidity and mortality worldwide. Cellular senescence is a hallmark of aging. The accumulation of senescent cells is causally associated with pathogenesis of various age-associated disorders. Due to their promise for alleviating age-related disorders and extending healthspan, therapeutic strategies targeting senescent cells (senotherapies) as a means to combat aging have received much attention over the past decade. Among the conventionally used approaches, one is the usage of small-molecule compounds to specifically exhibit cytotoxicity toward senescent cells or inhibit deleterious effects of the senescence-associated secretory phenotype (SASP). Alternatively, there are immunotherapies directed at surface antigens specifically upregulated in senescent cells (seno-antigens), including chimeric antigen receptor (CAR) therapies and senolytic vaccines. This review gives an update of the current status in the discovery and development of senolytic therapies, and their translational progress from preclinical to clinical trials. We highlight the current challenges faced by senotherapeutic development in the context of senescence heterogeneity, with the aim of offering novel perspectives for future anti-aging interventions aimed at enhancing healthy longevity.

Prevalence, associated factors, and impact of vitamin B12 deficiency in older medical inpatients

PURPOSE

This retrospective cohort study aims to explore the prevalence of vitamin B12 deficiency in older hospitalized adults and identify key factors associated with this deficiency, as well as its impact on frailty and functional decline.

METHODS

Data were collected from older adults (≥65 years) sequentially admitted to the Internal Medicine Department of a tertiary university hospital. Clinical and laboratory characteristics, including age, sex, somatometric data, cause of admission, past medical history, chronic medication use, and laboratory tests, were recorded. Frailty and functional status were assessed using the Fried Frailty Scale (FFS), Clinical Frailty Scale (CFS), Barthel Index, and Katz Index. Vitamin B12 levels on admission were categorised as deficient (<200 pg/ml), borderline (200-300 pg/ml), normal (300-999 pg/ml), and high (≥1000 pg/ml).

RESULTS

A total of 894 patients were included. The median age was 83 years and 487 (54.5%) were females. The prevalence of vitamin B12 deficiency was found in 9.1%, while 17.3% of the sample had borderline levels. Multivariate analysis identified polypharmacy (≥5 drugs), low albumin levels/Geriatric Nutritional Risk Index (GNRI), and nursing home residency as independent factors associated with low B12 levels. Multivariate analyses showed that B12 deficiency was significantly associated with higher frailty rates and lower functional status.

CONCLUSION

Vitamin B12 deficiency is prevalent among hospitalized older patients and is significantly associated with increased frailty and reduced functional status. These findings underscore the importance of routine screening for B12 deficiency in this vulnerable population to improve clinical outcomes and quality of life.
