Background: Hypertension remains a major contributor to global cardiovascular morbidity and mortality. Aldosterone, a key hormone in blood pressure regulation, plays a significant role in hypertension pathophysiology. This has led to growing interest in aldosterone synthase inhibitors (ASIs) as a potential treatment. This meta‐analysis aims to evaluate the efficacy and safety of ASIs in managing hypertension. Methods: A systematic search of PubMed, Google Scholar and Cochrane Central was conducted up to 13 July 2025, to identify randomised controlled trials (RCTs) evaluating ASIs in hypertensive adults. Data were analysed using RevMan version 5.4, employing random‐effects models with significance set at p < 0.05. Results: A total of 8 RCTs were included, with a total of 2003 participants in the ASI group and 650 participants in the placebo group. ASIs significantly reduced systolic blood pressure (SBP) compared to placebo (MD: −6.01 mmHg; 95% confidence interval [CI]: −9.31 to −2.71; I 2 = 85%; p = 0.0004); diastolic blood pressure (DBP) was found to be comparable between the two groups (MD: −2.20 mmHg; 95% CI: −4.46 to 0.06; I 2 = 69%; p = 0.06). There was a significant reduction in serum aldosterone levels favouring ASI use (MD: −1.46; 95% CI: −2.76 to −0.16; I 2 = 99%; p < 0.00001). The risk of serious (RD: 0.00; 95% CI: −0.01 to 0.02; I 2 = 30%; p = 0.75) and non‐serious adverse events (RD: 0.05; 95% CI: −0.02 to 0.12; I 2 = 64%; p = 0.20) did not differ significantly between ASI and placebo groups. However, ASI use was associated with a significantly higher risk of hyperkalemia (RD: 0.04; 95% CI: 0.02 to 0.06; I 2 = 70%; p = 0.002). Conclusion: ASIs effectively lower SBP and serum aldosterone in adults with hypertension. They appear safe overall but may increase the risk of hyperkalemia.

Anti-seizure medications (ASMs) are specific types of anticonvulsants used to treat epileptic seizures. However, several studies have shown an association between ASMs and an increased risk of hematological disorders, such as thrombocytopenia, aplastic anemia, and platelet function disorders leading to prolonged bleeding times. This review explores the existing literature on this topic, investigating a wide variety of ASMs, ranging from first-generation medications to newer ones. A comprehensive search was conducted on all the currently approved ASMs using PubMed and Google Scholar: review articles, clinical trials, meta-analysis, observational studies, case reports, and relevant animal studies were identified. We extracted 15 ASMs including valproic acid (VPA), carbamazepine, phenytoin, phenobarbital, diazepam, clonazepam, lamotrigine, levetiracetam, oxcarbazepine, felbamate, topiramate, pregabalin, lacosamide, cannabidiol (CBD), and perampanel that contain considerable literature regarding different coagulopathies. An in-depth review of over 140 studies revealed a robust association between ASM-induced changes and the onset of bleeding disorders via several different mechanisms. Polytherapy, the use of multiple ASMs, also emerged as a significant risk factor for the development of coagulopathies. This review highlights the potential link between ASMs and bleeding disorders, emphasizing the importance of considering this risk during treatment planning. By understanding these associations, healthcare providers can optimize patient outcomes and minimize bleeding risks. Additionally, this review identifies the need for further research to bridge current knowledge gaps in clinical pharmacology related to ASMs and bleeding disorders.

Background: Duchenne muscular dystrophy (DMD) is an X-linked disorder caused by DMD gene mutations, leading to muscle wasting due to dystrophin deficiency. Current treatment with corticosteroids like prednisone shows benefits but lacks clarity on optimal dosing regimens. This systematic review and meta-analysis aim to determine the efficacy and safety of daily versus intermittent prednisone dosing in DMD management. Methods: We conducted a systematic search of PubMed, Google Scholar, Embase, and Scopus databases to identify studies comparing daily versus intermittent prednisone in DMD treatment. The study protocol was registered with PROSPERO (CRD42024549050). Results: After the systematic search, 6 trials were included in the pooled analysis. Intermittent prednisone was associated with a higher prevalence of cushingoid appearance (RR: 1.72; 95% CI: 1.17 to 2.51; P = 0.005), excessive hair growth (RR: 1.56; 95% CI: 1.08 to 2.24; P = 0.02), and hypertension (RR: 3.42; 95% CI: 1.87 to 6.25; P < 0.0001). In contrast, there were no statistically significant differences between daily versus intermittent prednisone in terms of forced vital capacity (FVC), blood pressure, loss of ambulation, weight changes, weight gain, bone fracture, behavioral changes, and DEXA lumbar spine Z-scores. Conclusion: No significant differences in efficacy outcomes regimens were observed. However, intermittent prednisone was associated with a higher prevalence of certain adverse effects, such as cushingoid appearance, excessive hair growth, and hypertension. These findings provide valuable insights for clinicians when choosing treatment strategies and highlight the need for personalized approaches to minimize side effects while maintaining efficacy.

Background and Objectives: Growing evidence suggests a strong relationship between hypertension and cancer, which can increase the risk of poor prognosis. However, data regarding mortality related to cancer and hypertension are limited. Our study aims to analyze the mortality trends related to cancer and hypertension in the United States from 1999 to 2023. Materials and Methods: A retrospective observational analysis was conducted using mortality data for the adult U.S. population from 1999 to 2023, retrieved from the CDC WONDER database using death certificates. Age-adjusted mortality rates (AAMRs) were calculated, and annual percentage changes (APCs) were analyzed using JoinPoint Regression. Results: From 1999 to 2023, a total of 1,406,107 deaths related to cancer and hypertension were recorded in the United States. The AAMR increased from 12.59 in 1999 to 35.49 in 2023. Males had a higher mortality rate compared to women throughout the study period (AAMR; 30.3 vs. 20.4). Non-Hispanic (NH) Black Americans, or African Americans had the highest mortality rates, followed by NH white, Hispanic or Latino groups, and other NH groups. The highest AAMR was observed in the South, followed by the Midwest, the Northeast, and the West. Rural areas had higher mortality rates compared to urban areas. Conclusions: Cancer- and hypertension-related mortality rates have consistently increased in the United States from 1999 to 2023, particularly affecting males, NH Black Americans, the southern region, and rural areas. The trends highlight the need for targeted prevention, including early screening, lifestyle changes, and treatment adherence.

Background: Cardiac involvement in sarcoidosis is often subclinical, with late manifestations associated with poorer prognosis. Speckle-tracking echocardiography (STE) is gaining attention due to its ability to detect subclinical alterations in myocardial contraction patterns and quantification of abnormal parameters. Methods: Databases, including PubMed, Cochrane Central, Embase, Scopus, and Web of Science, were searched to identify studies comparing echocardiographic parameters in sarcoidosis patients with healthy controls. Mean difference (MD) with 95% confidence intervals (CI) were pooled using the inverse-variance random-effects model in Review Manager Version 5.4.1. Statistical significance was considered at p-value <0.05. Results: Thirteen studies with 1416 participants (854—sarcoidosis; 562—healthy controls) were included. In a pooled analysis, patients with sarcoidosis demonstrated a significantly lower left ventricular global longitudinal strain (LV GLS) (Mean Difference [MD]: −3.60; 95% Confidence Interval [CI]: −4.76, −2.43; p < 0.0001) and left ventricular global circumferential strain (LV GCS) (MD: −2.52; 95% CI: −4.61, −0.43; p = 0.02), along with a significantly higher pulmonary artery systolic pressure (PASP) (MD: 4.19; 95% CI: 0.08, 8.29; p = 0.05), left ventricular end-systolic diameter (LVESD) (MD: 0.90; 95% CI: 0.10, 1.71; p = 0.03), A-wave velocity (MD: 3.36; 95% CI: 0.33, 6.39; p = 0.03), and E/E’ ratio (MD: 1.33; 95% CI: 0.42, 2.23; p = 0.004) compared to healthy controls. No significant differences were noted in left ventricular ejection fraction (LVEF), left ventricular global radial strain (LV GRS), interventricular septal thickness (IVST), tricuspid annular plane systolic excursion (TAPSE), left ventricular end-diastolic diameter (LVEDD), E-wave velocity, and E/A ratio. Conclusions: STE serves as a promising imaging modality in detecting subclinical cardiac involvement in sarcoidosis patients with no overt cardiac manifestations. A widespread cardiovascular evaluation of sarcoidosis patients with STE is recommended to detect these altered myocardial contractile patterns. The early detection of cardiac sarcoidosis is essential to prevent adverse clinical outcomes and improve mortality.

Background: Sarcoidosis is a multisystem disorder characterized by non-caseating granulomas in various organs. While cardiac sarcoidosis (CS) is clinically rare, it has significant implications, including heart failure, ventricular arrhythmias, and sudden cardiac death. Speckle-tracking echocardiography has emerged as a promising tool for detecting subclinical myocardial dysfunction, which is cost-efficient and readily available. This meta-analysis aims to evaluate differences in functional echocardiographic parameters between patients with CS and extracardiac sarcoidosis (ECS) to improve early recognition and management. Methods: A comprehensive search of major bibliographic databases was conducted to identify studies up to December 2024. Mean differences (MDs) with 95% CIs were pooled using the inverse-variance random-effect model. Results: Seven studies with 478 patients with sarcoidosis (CS: 159 and ECS: 319) were included. Patients with CS had a significant reduction in left ventricular global longitudinal strain (MD: −2.73; 95% CI: −4.09, −1.38; p < 0.0001) and tricuspid annular plane systolic excursion (MD: −0.59; 95% CI: −1.12, −0.05; p = 0.03) compared to patients with ECS. No significant differences in the LV global circumferential strain, interventricular septum thickness, left ventricular ejection fraction, E/A ratio, E/E’ ratio, LV end-diastolic diameter, and LV end-systolic diameter were noted. Conclusions: LV GLS and TAPSE are promising parameters for the early detection of cardiac involvement in sarcoidosis, with significant prognostic implications. Although STE provides a cost-effective and accessible alternative to CMR and FDG-PET, further research is needed to standardize its use and validate diagnostic cut-offs.
