The value of whole tumor apparent diffusion coefficient histogram parameters in predicting meningiomas progesterone receptor expression.

This letter provides a critical assessment of a previous study on the utility of whole tumor apparent diffusion coefficient (ADC) histogram characteristics in predicting meningioma progesterone receptor expression. While acknowledging the benefits of employing classical diffusion-weighted imaging (DWI) for non-invasive tumor evaluation, it also emphasizes significant drawbacks. Advanced imaging techniques such as diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) were not used in the study, which could have provided a more comprehensive understanding of tumor microstructure and heterogeneity. Furthermore, the inclusion of necrotic and cystic areas in ADC analysis may distort results due to their different diffusion properties. While focusing on first-order ADC histogram characteristics is useful, it ignores the potential insights gained from higher-order features and texture analysis. These limitations indicate that future research should combine improved imaging modalities with thorough analytical methodologies to increase the predictive value of imaging biomarkers for meningioma features and progesterone receptor expression.

Commentary on "Relationship between miRNA-21, miRNA-155, and miRNA-182 expression and inflammatory factors in cerebrospinal fluid from patients with multiple sclerosis".

This letter provides insightful perspectives on multiple sclerosis (MS) biomarkers, building upon Behrouz Shademan et al.'s study on miRNA-21, miRNA-155, and miRNA-182 [1]. Beyond these miRNAs, we delve into recent advancements, highlighting promising biomarkers such as ELTD1, CHI3L1, and Fecal Lcn-2. ELTD1 exhibits potential for MS diagnosis, CHI3L1 correlates with disability aspects, and Fecal Lcn-2 serves as a sensitive indicator for gut dysbiosis. Our exploration underscores the evolving landscape of MS biomarker research, urging further investigation for integrating these new markers into diagnostic and monitoring strategies.

Cost-Effectiveness Analysis of Sacubitril/Valsartan for Reducing the Use of Implantable Cardioverter-Defibrillator (ICD) and the Risk of Death in ICD-Eligible Heart Failure Patients With Reduced Ejection Fraction.

This critical review of Kaddoura et al.'s article on sacubitril/valsartan in heart failure patients underscores the importance of considering potential adverse effects, including renal failure, hyperkalemia, angioedema, and increased reports of sudden cardiac death. It highlights the need for rigorous monitoring and precise treatment regimens, especially in diabetic heart failure patients. Additionally, the review questions the generalizability of the study's results to diverse healthcare settings and emphasizes the importance of grounded patient follow-up data for accurate long-term assessment. These considerations are vital for informed decision-making regarding sacubitril/valsartan use in heart failure management.
