Ultrasound evaluation of the placenta in healthy and placental syndrome pregnancies: A systematic review.

Eur J Obstet Gynecol Reprod Biol 2021 May 4;262:45-56. Epub 2021 May 4.

Department of Obstetrics and Gynecology, Maastricht University Medical Centre (MUMC+), the Netherlands.

Introduction: An antepartum screening method to determine normal and abnormal placental function is desirable in the prevention of maternal and fetal pregnancy complications. Placental appearance can easily be obtained and evaluated using 2D ultrasonography, but surprisingly little is known about the change in placental appearance during gestation. Aim of this systematic review was to describe the antepartum placental appearance in placenta syndrome (PS) pregnancies, and to compare this to the appearance in healthy pregnancies. Read More

Pseudo heparin resistance after pulmonary endarterectomy: Role of thrombus production of Factor VIII.

Semin Thorac Cardiovasc Surg 2021 May 10. Epub 2021 May 10.

Division of Thoracic Surgery, Toronto General Hospital, University Health Network, Toronto, ON, Canada; Latner Thoracic Surgery Research Laboratories, Toronto General Hospital Research Institute, University Health Network, Toronto, ON, Canada. Electronic address:

Pulmonary endarterectomy (PEA) is the main treatment for chronic thromboembolic pulmonary hypertension (CTEPH). Postoperative unfractionated heparin dosing can be monitored by activated partial thromboplastin time (APTT) or by anti-factor Xa activity (anti-Xa). In pseudo heparin resistance, APTT response to heparin is blunted due to elevated Factor VIII (FVIII) which can underestimate anticoagulation. Read More

Targeting fibrosis in the failing heart with nanoparticles.

Adv Drug Deliv Rev 2021 May 10. Epub 2021 May 10.

Department of Medicine and Health Sciences "Vincenzo Tiberio", University of Molise, Campobasso, Italy; Interdepartmental Center for Nanotechnology Research-NanoBem, University of Molise, Campobasso, Italy. Electronic address:

Heart failure (HF) is a clinical syndrome characterized by typical symptoms and signs caused by a structural and/or functional cardiac abnormality, resulting in a reduced cardiac output and/or elevated intracardiac pressures at rest or during stress. Due to increasing incidence, prevalence and, most importantly mortality, HF is a healthcare burden worldwide, despite the improvement of treatment options and effectiveness. Acute and chronic cardiac injuries trigger the activation of neurohormonal, inflammatory, and mechanical pathways ultimately leading to fibrosis, which plays a key role in the development of cardiac dysfunction and HF.

Basic Principles and New Advances in Kidney Imaging.

Kidney Int 2021 May 10. Epub 2021 May 10.

Division of Nephrology and Hypertension, Mayo Clinic, Rochester, MN, USA.

Over the past few years, clinical renal imaging has seen great advances, allowing assessments of kidney structure and morphology, perfusion, function and metabolism, oxygenation, as well as microstructure and interstitium. Medical imaging is becoming increasingly important in the evaluation of kidney physiology and pathophysiology, showing promise in management of patients with renal disease, in particular with regard to diagnosis, classification, and prediction of disease development and progression, monitoring response to therapy, detection of drug toxicity, and patient selection for clinical trials. A variety of imaging modalities, ranging from routine to advanced tools, are currently available to probe the kidney both spatially and temporally, particularly ultrasonography, computed tomography, positron emission tomography, renal scintigraphy, and multiparametric magnetic resonance imaging.

Depressive-hypertension: A proposed human endotype of brain/gut microbiome dysbiosis.

Am Heart J 2021 May 10:100540. Epub 2021 May 10.

Department of Physiology and Functional Genomics, University of Florida College of Medicine, Gainesville.

Background: Hypertension is frequently linked with depression in adults with cardiovascular disease (CVD), yet the underlying mechanism and successful management remain elusive. We approached this knowledge gap through the lens that humans are eukaryote-prokaryote "meta-organisms", such that CVD dysregulation is a mosaic disorder involving dysbiosis of the gut. We hypothesized that patients diagnosed with hypertension plus depression harbor a unique gut microbial ecology with attending functional genomics engaged with their hosts' gut/brain axis physiology.

Cardiac Energy Metabolism in Heart Failure.

Circ Res 2021 May 13;128(10):1487-1513. Epub 2021 May 13.

Division of Endocrinology and Metabolism, University of Iowa Carver College of Medicine, Iowa City (E.D.A.).

Alterations in cardiac energy metabolism contribute to the severity of heart failure. However, the energy metabolic changes that occur in heart failure are complex and are dependent not only on the severity and type of heart failure present but also on the co-existence of common comorbidities such as obesity and type 2 diabetes. The failing heart faces an energy deficit, primarily because of a decrease in mitochondrial oxidative capacity. Read More

From Systemic Inflammation to Myocardial Fibrosis: The Heart Failure With Preserved Ejection Fraction Paradigm Revisited.

Circ Res 2021 May 13;128(10):1451-1467. Epub 2021 May 13.

RHJ Department of Veterans Affairs Medical Center, Medical University of South Carolina, Charleston (M.R.Z.).

In accordance with the comorbidity-inflammation paradigm, comorbidities and especially metabolic comorbidities are presumed to drive development and severity of heart failure with preserved ejection fraction through a cascade of events ranging from systemic inflammation to myocardial fibrosis. Recently, novel experimental and clinical evidence emerged, which strengthens the validity of the inflammatory/profibrotic paradigm. This evidence consists among others of (1) myocardial infiltration by immunocompetent cells not only because of an obesity-induced metabolic load but also because of an arterial hypertension-induced hemodynamic load.
