Researchers at the Johns Hopkins Kimmel Cancer Center in Baltimore, working with colleagues in the Netherlands, developed a blood test that can predict recurrence of gastric cancer in patients after surgery. A description of their test, which is still experimental, was published online Jan. 27 in the journal Nature Communications.
Evaluating the effectiveness of therapies for neurodegenerative diseases is often difficult because each patient’s progression is different. A new study shows artificial intelligence (AI) analysis of blood samples can predict and explain disease progression, which could one day help doctors choose more appropriate and effective treatments for patients.
Researchers at Beth Israel Deaconess Medical Center (BIDMC) have found that orthostatic hypotension was not associated with higher risk of cardiovascular events, falls, or fainting among participants in The Systolic Blood Pressure Intervention Trial. In a study published in the journal Hypertension, the scientists showed that hypertension treatment had no impact on the link between OH and cardiovascular outcomes or other adverse events.
A new study led by physician-researchers at Beth Israel Deaconess Medical Center (BIDMC) reports that the antihypertensive drug amlodipine lowered long-term gout risk compared to two other drugs commonly prescribed to lower blood pressure. The findings are published in the Journal of Hypertension.
The DNA molecule inside the nucleus of any human cell is more than six feet long. To fit into such a small space, it must fold into precise loops that also govern how genes are turned on or off. New research at Washington University School of Medicine in St. Louis indicates that "jumping genes" play a surprising role in stabilizing the 3D folding patterns of the DNA molecule inside the cell’s nucleus.
Overcoming HIV latency – activating HIV in CD4+ T cells that lay dormant – is a needed step toward a cure. Scientists at UNC-Chapel Hill, Emory University, and Qura Therapeutics – a partnership between UNC and ViiV Healthcare – showed it’s possible to drive HIV out of latency in two animal models.
Blood tests could replace menstrual periods as a gauge for when a women is nearing menopause, according to new research published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Treating septic shock in children with a combination of intravenous vitamin C, vitamin B1 and hydrocortisone (a commonly used steroid) is associated with lower mortality, according to a study from Ann & Robert H. Lurie Children’s Hospital of Chicago. This is the first pediatric study of the safe and relatively inexpensive treatment for septic shock, and the preliminary data supports the promising outcomes seen in adults. Findings were published in the American Journal of Respiratory and Critical Care Medicine.
In diseases like cancer, atherosclerosis, and sickle cell anemia, cathepsins promote their propagation. Drug trials to inhibit these enzymes have failed due to baffling side effects. Now a new study examines cathepsins in systems to remove some of the bafflement.
McMaster University researchers surveyed the data of patients of Hamilton’s two hospital systems over nine years and found 52 with low Vitamin C levels. This included 13 patients who could be diagnosed as having scurvy, and an additional 39 who tested positive for scurvy but did not have documented symptoms. Among those with scurvy, some were related to alcohol use disorder or to bariatric surgery but the majority were related to other causes of malnutrition such as persistent vomiting, purposeful dietary restrictions, mental illness, social isolation and dependence on others for food.
The Jan. 17 issue of the Journal of the American Medical Association (JAMA) features an important study about sepsis with an accompanying editorial by a University of Nebraska Medical Center expert. The study and editorial sets the record straight on an unproven therapy some physicians use to treat sepsis, a deadly infectious disease. The editorial, written by Andre Kalil, M.D., M.P.H., professor of infectious diseases in the UNMC Department of Internal Medicine, writes in support of the new and rigorous international study based on a randomized clinical trial in Australia, published in the same issue. The editorial appears in the Jan. 17 online issue and also will appear in the Feb. 4 print edition.
University of Colorado Cancer Center study shows healthy form of the leukemia-causing gene MLL may push pluripotent stem cells (which have proven difficult to use in human patients) to become durable hematopoietic stem cells (which are usable in patients, but have until now been impossible to make).
Researchers from St. Jude Children’s Research Hospital and the Chinese Children’s Cancer Group led the first randomized, Phase III clinical trial comparing targeted therapies for acute lymphoblastic leukemia (ALL) driven by the Philadelphia chromosome. Results showed that the drug dasatinib provides more benefit than the standard of care, which led to changes in the way this leukemia is treated. The findings were reported today in JAMA Oncology.
A team of physicists from McMaster University has developed a process to modify red blood cells so they can be used to distribute drugs throughout the body, which could specifically target infections or treat catastrophic diseases such as cancer or Alzheimer’s.
A nanoparticle carrier system that could eliminate the need for bone marrow transplants, which are both expensive and difficult for patients to undergo. The University of Delaware's Emily Day, an assistant professor of biomedical engineering, is developing a platform that could treat stem cells directly without the need to remove them from the body.
A new study from Washington University School of Medicine in St. Louis suggests that extremely rare, harmful genetic mutations present in healthy donors’ stem cells — though not causing health problems in the donors — may be passed on to cancer patients receiving stem cell transplants, potentially creating health problems for the recipients. Among the concerns are heart damage, graft-versus-host disease and possible new leukemias.
Responders who worked at the World Trade Center site after the attacks on September 11, 2001, have an increased overall cancer incidence compared to the general population, particularly in thyroid cancer, prostate cancer, and, for the first time ever reported, leukemia, according to a Mount Sinai study published in JNCI Cancer Spectrum in January.
Investigators at John Theurer Cancer Center at Hackensack University Medical Center in New Jersey were part of the CANDOR global phase III clinical trial for patients with refractory (persistent) multiple myeloma.

Novel research shows that a blood test can differentiate elderly concussion patients with brain tissue damage from those without it. This finding, published in the special brain health collection of AACC’s The Journal of Applied Laboratory Medicine, could help ensure that elderly patients with severe concussions receive crucial treatment for their injuries.
Moll was the only non-NASA physician NASA consulted when it was discovered that an astronaut aboard the ISS had a deep vein thrombosis (DVT) – or blood clot – in the jugular vein of their neck.
Researchers found a way to create lasers smaller than red blood cells.
The VISION study looked at whether levels of a cardiac blood test, NT-proBNP, measured before surgery can predict cardiac and vascular complications. Higher levels of NT-proBNP, which can be caused by various anomalies in the cardiac muscle, such as stress, inflammation or overstretch, can help identify which patients are at greatest risk of cardiac complications after surgery. The study included 10,402 patients aged 45 years or older having non-cardiac surgery with overnight stay from 16 hospitals in nine countries.
