Los investigadores de Mayo Clinic en Florida y sus colaboradores descubrieron que un biomarcador sanguíneo podría determinar la extensión del daño cerebral causado por diferentes tipos de accidentes cerebrovasculares y dar un pronóstico para estos pacientes.

Blood clots are the biggest cause of death in patients with inflammatory bowel disease (IBD) ─ ulcerative colitis or Crohn's disease. In a retrospective study recently published in the journal Gastroenterology, Cedars-Sinai investigators found that a combination of rare and common genetic variants in some IBD patients significantly increased their risk of developing clot-causing thromboembolic diseases.

Genetic mutations that promote the growth of the most common type of adult brain tumors can be accurately detected and monitored in blood samples using an enhanced form of liquid biopsy developed by researchers at Massachusetts General Hospital (MGH).
An aneurysm is a weak spot in the blood vessel in the brain and over time it starts to balloon out and has the potential to rupture. Dr. Ahsan Sattar, director of Neuroendovascular Surgery and Stroke at Mountainside Medical Center, states the aneurysm cause is multifactorial; high blood pressure, smoking, family history of brain aneurysms, natural aging, and genetics. Dr. Sattar does add that often there are no warning signs of a brain aneurysm prior to a rupture, naming it a “silent killer.” Patients will often experience the “worst headache of their life and should report to the nearest appropriate emergency room,” said Dr. Sattar. Mountainside Medical Center’s Neuroscience Institute offers a special MRI called a MR Angiogram (MRA), which evaluates the blood vessels in the brain in great detail - the best screening tool for aneurysms. This test is preferred since it is quick and does not expose the patient to any radiation. A CT Angiogram (CTA) can also be performed if the patient i

People who are given clot-busting drugs after a stroke may recover better if they also are given a therapy called remote ischemic postconditioning, according to a new study published in the October 7, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. Remote ischemic conditioning is when blood flow, and the oxygen it carries, is stopped and then restored repeatedly by blood pressure cuffs worn on the arms.
The study found the drug can help the most severely injured trauma patients.

Although there is still uncertainty about the clinical benefits and role of convalescent plasma to treat COVID-19, new research suggests that the earlier plasma is collected after the donor's recovery from COVID-19, the better, as antibodies start to disappear after three months of symptom onset.
In a systematic review of the worldwide published data on "Venous thromboembolism (VTE) in COVID-19 patients", Cihan Ay, Stephan Nopp, and Florian Moik from the Department of Medicine I, Clinical Division of Haematology and Haemostaseology, now for the first time, provide an in-depth analysis on the risk of VTE in patients hospitalised for COVID-19.
A new study published in the journal Critical Care Explorations shows for the first time that part of the stress response in people and animals involves increasing the levels of a naturally circulating element in blood. The discovery demonstrates a biological mechanism that rapidly responds to severe physiologic stress and potentially serves to protect us from further damage due to life-threatening conditions.

Some critically ill patients with septic shock need medications called vasopressors to correct dangerously low blood pressure. When high doses of vasopressors are needed or blood pressure isn’t responding well, the steroid hydrocortisone is often used. In this situation, earlier treatment with hydrocortisone reduces the risk of death and other adverse outcomes, reports a study in SHOCK®: Injury, Inflammation, and Sepsis: Laboratory and Clinical Approaches, Official Journal of the Shock Society. The journal is published in the Lippincott portfolio by Wolters Kluwer.
Adults with fatter legs -- meaning they have a higher percentage of total body fat tissue in their legs -- were less likely than those with a lower percentage to have high blood pressure, according to new research to be presented Sept. 10-13, 2020, at the virtual American Heart Association's Hypertension 2020 Scientific Sessions.

After nearly 15 years on an upward trend, awareness among Americans about their high blood pressure and rates of blood pressure control are now on the decline. many groups, including older adults and Black adults, are less likely than they were in earlier years to control their blood pressure.
Early findings from researchers at Children’s Hospital of Philadelphia (CHOP) show that convalescent plasma appears to be a safe and possibly effective treatment for children with life-threatening cases of COVID-19. The results were published online Friday by the journal Pediatric Blood and Cancer.
Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago were the first to examine endothelial cells – one of the main sources of blood production – for clues as to why people with Down syndrome have higher prevalence of leukemia. They identified a new set of genes that are overexpressed in endothelial cells of patients with Down syndrome. This creates an environment conducive to leukemia, which is characterized by uncontrolled development and growth of blood cells. Their findings, published in the journal Oncotarget, point to new potential targets for treatment and possibly prevention of leukemia, in people with Down syndrome and in the general population.
