J Perinat Med 2021 Jun 11. Epub 2021 Jun 11.

Ann & Robert H. Lurie Children's Hospital of Chicago, Northwestern University Feinberg School of Medicine, Chicago, IL, USA.

After more than 1 year of the SARS-CoV-2 pandemic, a great deal of knowledge on how this virus affects pregnant women, the fetus and the newborn has accumulated. The gap between different guidelines how to handle newborn infants during this pandemic has been minimized, and the American Academy of Pediatrics (AAP)'s recommendations are now more in accordance with those of the World Health Organization (WHO). In this article we summarize present knowledge regarding transmission from mother to the fetus/newborn. Read More

Should we screen Eastern Mediterranean COVID-19 patients for inherited thrombophilia?

Med Hypotheses 2021 Jun 4;152:110621. Epub 2021 Jun 4.

Department of Internal Medicine, American University of Beirut Medical Center, Beirut, Lebanon. Electronic address:

The inflammatory component of Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) creates a pro-thrombotic state that necessitates a thrombophylactic strategy for hospitalized patients. Such strategies are difficult to be standardized because certain individuals can have pro-thrombotic conditions, such as inherited thrombophilia, which pre-dispose them to an additional coagulative risk. Whether outside the hospital or when admitted, patients with inherited thrombophilia need special anticoagulant and antiplatelet attention. Read More

Biplane mode for more precise intrauterine procedures.

Am J Obstet Gynecol 2021 Jun 8. Epub 2021 Jun 8.

Department of Obstetrics and Fetal Medicine, Necker Enfants-Malades Hospital, Paris Descartes University, Paris, France; Université de Paris, Paris, France.

The evolution of ultrasound and the introduction of three and four-dimensional ultrasound techniques led to a shift in the perception and usage of ultrasound in fetal medicine. The biplane mode might help in multiple fetal procedures, including but not limited to, basic intrauterine thoracocentesis, thoraco-amniotic shunting, amnioreduction, amnioinfusion, cordocentesis, intraumbilical infusion and ِumbilical cord coagulation, with a possible reduction in the complication rate. Despite its theoretical usefulness, more studies are required to assess the clinical importance of this technique. Read More

Pathophysiological Aspects of the Development of Abdominal Aortic Aneurysm with a Special Focus on Mitochondrial Dysfunction and Genetic Associations.

Biomol Concepts 2021 Jun 11;12(1):55-67. Epub 2021 Jun 11.

Department of Basic Research, Institute for Atherosclerosis Research, Moscow121609, Russia.

Abdominal aortic aneurysm (AAA) is a complex degenerative vascular disease, with considerable morbidity and mortality rates among the elderly population. The mortality of AAA is related to aneurysm expansion (the enlargement of the aortic diameter up to 30 mm and above) and the subsequent rupture. The pathogenesis of AAA involves several biological processes, including aortic mural inflammation, oxidative stress, vascular smooth muscle cell apoptosis, elastin depletion, and degradation of the extracellular matrix.

Review of the hydraulic capacity of urban grate inlet: a global and Latin American perspective.

Water Sci Technol 2021 Jun;83(11):2575-2596

Facultad de Minas, Departamento de Geociencias y Medio Ambiente, National University of Colombia - Sede Medellín, Medellín, Cr. 80 # 65-223, Colombia.

The most recent numerical models of urban drainage allow the integration of runoff from roads with the network of sewer pipes, thus evolving towards a holistic version of the system. A fundamental part of this integration is the capture of stormwater in urban drain inlets. These studies have recently increased, resulting in different methodologies to represent the uptake process and making it difficult to apply unified or general formulations. Read More

Department of Anatomy, Physiology, and Genetics, Uniformed Services University of the Health Sciences, F. Edward Hébert School of Medicine, Bethesda, MD, USA.

Background: Spinal muscular atrophy is an inherited neurodegenerative disease caused by insufficient levels of the survival motor neuron (SMN) protein. Recently approved treatments aimed at increasing SMN protein levels have dramatically improved patient survival and have altered the disease landscape. While restoring SMN levels slows motor neuron loss, many patients continue to have smaller muscles and do not achieve normal motor milestones. Read More

Coping with stress in a warming Gulf: the postlarval American lobster's cellular stress response under future warming scenarios.

Cell Stress Chaperones 2021 Jun 11. Epub 2021 Jun 11.

School of Marine Sciences, University of Maine, Orono, ME, 04469, USA.

The Gulf of the Maine (GoM) is one of the fastest warming bodies of water in the world, posing serious physiological challenges to its marine inhabitants. Marine organisms can cope with the cellular and molecular stresses created by climate change through changes in gene expression. We used transcriptomics to examine how exposure to current summer temperatures (16 °C) or temperature regimes reflective of projected moderate and severe warming conditions (18 °C and 22 °C, respectively) during larval development alters expression of transcripts affiliated with the cellular stress response (CSR) in postlarval American lobsters (Homarus americanus).
