An Original Aspirin-Containing Carbonic Anhydrase 9 Inhibitor Overcomes Hypoxia-Induced Drug Resistance to Enhance the Efficacy of Myocardial Protection.

Cardiovasc Drugs Ther 2021 Apr 12. Epub 2021 Apr 12.

Jiangsu Province Hi-Tech Key Laboratory for Biomedical Research, Southeast University, Nanjing, 211189, Jiangsu, People's Republic of China.

Purpose: Hypoxic microenvironment plays a vital role in myocardial ischemia injury, generally leading to the resistance of chemotherapeutic drugs. This induces an intriguing study on mechanism exploration and prodrug design to overcome the hypoxia-induced drug resistance.

Methods: In this study, we hypothesized that the overexpression of carbonic anhydrase 9 (CAIX) in myocardial cells is closely related to the drug resistance. Read More

Preventing Recurrent Preeclampsia by Tailored Treatment of Nonphysiologic Hemodynamic Adjustments to Pregnancy.

Hypertension 2021 Apr 5:HYPERTENSIONAHA12016502. Epub 2021 Apr 5.

Department of Obstetrics and Gynecology (E.G.M., E.C., V.A.L.v.B., V.M.M.M.S., R.-J.A., M.E.A.S.).

Preeclampsia is often preceded by abnormal hemodynamic changes with heterogeneous patterns in the first half of pregnancy. We assessed the effect of timely tailored correction of nonphysiological hemodynamic changes on preventing preeclampsia in a high-risk population. Primiparous women with a history of preeclampsia were invited to participate in a longitudinal program in their next pregnancy, including repeated hemodynamic assessments at 12-, 16-, 20- and 30-week gestation additional to regular pregnancy checkups.

An integrated model of preeclampsia: a multifaceted syndrome of the maternal cardiovascular-placental-fetal array.

Am J Obstet Gynecol 2021 Mar 9. Epub 2021 Mar 9.

Department of Obstetrics and Gynecology, Hadassah-Hebrew University Medical Center, Jerusalem, Israel.

Maternal tolerance of the semiallogenic fetus necessitates conciliation of competing interests. Viviparity evolved with a placenta to mediate the needs of the fetus and maternal adaptation to the demands of pregnancy and to ensure optimal survival for both entities. The maternal-fetal interface is imagined as a 2-dimensional porous barrier between the mother and fetus, when in fact it is an intricate multidimensional array of tissues and resident and circulating factors at play, encompassing the developing fetus, the growing placenta, the changing decidua, and the dynamic maternal cardiovascular system.

Overview of Aspirin and Platelet Biology.

Am J Cardiol 2021 04;144 Suppl 1:S2-S9

AtheroThrombosis Research Unit. Icahn School of Medicine at Mount Sinai Mount Sinai Heart. Mount Sinai Hospital, New York, New York. Electronic address:

Aspirin (ASA) has historically been one of the most important drugs in cardiology and has long been the cornerstone of antiplatelet therapy. Although its role in acute coronary syndrome remains undisputed, emerging data suggest that reappraisal of the efficacy of long-term ASA in some primary and secondary prevention may be warranted. The aim of this review is to place these new results in the context of previous evidence on aspirin by appraising the current body of evidence on its use of for cardiovascular diseases. Read More

Unfavorable Changes of Platelet Reactivity on Clopidogrel Therapy Assessed by Impedance Aggregometry Affect a Larger Volume of Acute Ischemic Lesions in Stroke.

Diagnostics (Basel) 2021 Feb 27;11(3). Epub 2021 Feb 27.

Center of Neurology, Vilnius University, LT-08661 Vilnius, Lithuania.

Background: High on-treatment platelet reactivity or its equivalent-resistance to the antiplatelet agent-significantly reduces the efficacy of the therapy, contributing to a negative impact on stroke course. Previous studies demonstrated that aspirin resistance is associated with a larger size of acute ischemic infarct. Due to the increasing use of clopidogrel in the secondary prevention of stroke, we aimed to assess the impact of clopidogrel resistance on the size and extent of ischemic lesions, both acute and chronic.

2021 Update on the Clinical Management and Diagnosis of Kawasaki Disease.

Curr Infect Dis Rep 2021 6;23(3). Epub 2021 Feb 6.

Division of Pediatric Infectious Diseases, Children's Hospital of Michigan, Detroit, MI USA.

Purpose Of Review: Provide an updated review of the clinical management and diagnosis of Kawasaki disease with inclusion of potential diagnostic difficulties with multisystem inflammatory syndrome in children (MIS-C) given the ongoing COVID-19 pandemic.

Recent Findings: Adjunctive corticosteroid therapy has been shown to reduce the rate of coronary artery dilation in children at high risk for IVIG resistance in multiple Japanese clinical studies (most notably RAISE study group). Additional adjunctive therapies (etanercept, infliximab, cyclosporin) may also provide limited benefit, but data is limited to single studies and subgroups of patients with cardiac abnormalities.

Low miR-19b-1-5p Expression Is Related to Aspirin Resistance and Major Adverse Cardio- Cerebrovascular Events in Patients With Acute Coronary Syndrome.

J Am Heart Assoc 2021 Jan 14;10(2):e017120. Epub 2021 Jan 14.

Departments of Clinical Epidemiology, Biostatistics and Bio-informaticsAmsterdam UMC, location AMC Amsterdam The Netherlands.

Background Because of a nonresponse to aspirin (aspirin resistance), patients with acute coronary syndrome (ACS) are at increased risk of developing recurrent event. The in vitro platelet function tests have potential limitations, making them unsuitable for the detection of aspirin resistance. We investigated whether miR-19b-1-5p could be utilized as a biomarker for aspirin resistance and future major adverse cardio-cerebrovascular (MACCE) events in patients with ACS. Read More

Department of Neurology, Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Toruń, Skłodowskiej 9 Street, 85-094 Bydgoszcz, Poland.

Effective platelet inhibition is the main goal of the antiplatelet therapy recommended as a standard treatment in the secondary prevention of non-embolic ischemic stroke. Acetylsalicylic acid (aspirin) and clopidogrel are commonly used for this purpose worldwide. A low biological response to antiplatelet agents is a phenomenon that significantly reduces the therapeutic and protective properties of the therapy. Read More

Effect of acetylsalicylic acid on inflamed adipose tissue. Insulin resistance and hepatic steatosis in a mouse model of diet-induced obesity.

Life Sci 2021 Jan 24;264:118618. Epub 2020 Oct 24.

Dipartimento di Scienze Farmacologiche e Biomolecolari, Università degli Studi di Milano, via Trentacoste 2, Milan, Italy. Electronic address:

Aims: Obesity represents a global health problem. Excessive caloric intake promotes the release of inflammatory mediators by hypertrophic adipocytes and obesity-induced inflammation is now recognized as a risk factor for the development of several diseases, such as cardiovascular diseases, insulin resistance, type-II diabetes, liver steatosis and cancer. Since obesity causes inflammation, we tested the ability of acetylsalicylic acid (ASA), a potent anti-inflammatory drug, in counteracting this inflammatory process and in mitigating obesity-associated health complications.
