Recent news about scientific and medical research from the Massachusetts General Hospital Research Institute.
A study by a multi-institutional research team has tracked the long-term incidence of death following ischemic and bleeding events occurring in patients more than one year after placement of a coronary stent. Their study appearing in the current issue of JAMA Cardiology found that ischemic events—those caused by a blockage in blood flow to the heart or brain—occurred more frequently than bleeding events in the 12 to 33 months after stenting and that both types of events incurred a serious mortality risk.
A team of researchers from Massachusetts General Hospital and the Harvard T.H. Chan School of Public Health reported that the Deferred Action for Childhood Arrivals (DACA) program appears to have reduced depression among eligible undocumented immigrants, often referred to as the “Dreamers.”
A study led by a Massachusetts General Hospital pediatrician finds that children ages 3 to 7 who don’t get enough sleep are more likely to have problems with attention, emotional control and peer relationships in mid-childhood.
A study from investigators at Massachusetts General Hospital finds that a blood transfusion practice previously studied only in patients with severe traumatic injuries has been widely adopted within the hospital for patients without traumatic injuries. Not only has this practice not been shown to benefit non-trauma patients, the study suggests that it may be harmful to some, an observation that indicates the need for more research.
Massachusetts General Hospital (MGH) and Brigham and Women’s Hospital (BWH) investigators have developed two approaches to increasing the use of penicillins and cephalosporins – highly effective antibiotics that are not as problematic as many alternatives – in hospitalized patients previously believed to be allergic to penicillin.
Parkinson’s disease researchers at Massachusetts General Hospital have launched an observational substudy designed to test the feasibility and accuracy of using patient-owned smartphones to measure symptoms of Parkinson’s disease.
A gene variant that produces red hair and fair skin in humans and in mice, which increases the risk of the dangerous skin cancer melanoma, may also contribute to the known association between melanoma and Parkinson’s disease.
Though the practice of acupuncture predates current understanding of physiology by several millennia, it often provides measureable improvements in health outcomes, particularly in the area of chronic pain. Now, in a study reported in the journal Brain, a team of investigators based at the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) sheds new light on the question of how.
Massachusetts General Hospital researchers have found how a variant in an important epigenetic enzyme – previously associated with Crohn’s disease and other immune disorders – interferes with the action of the innate immune system, potentially upsetting the balance between the microbial population of the gastrointestinal tract and the immune response.
A clinical trial for a new drug to prevent attacks of hereditary angiodema—a rare disorder characterized by recurrent swelling in the tissues in the face, hands, gastrointestinal tract and airway—has had promising results.
The combined results of two ovarian cancer screening trials suggest that a personalized strategy involving frequent screening of high-risk women could improve the chance that tumors are detected at early stages when they are easier to treat.
Massachusetts General Hospital researchers have identified a mechanism that controls the expression of genes regulating the growth of the most aggressive form of medulloblastoma, the most common pediatric brain tumor.
Three people with paralysis used the BrainGate brain-computer interface to type on a screen with unprecedented speed and accuracy, according to a new study published in eLife.
Current and former smokers suffering from illnesses like chronic lung or cardiovascular disease are more likely than healthy smokers to use e-cigarettes.
A new global collaborative study has confirmed that vitamin D supplementation can help protect against acute respiratory infections.
A study from Massachusetts General Hospital researchers has found that a pattern of gene variants associated with a body type in which weight is deposited around the abdomen increases the risk for Type 2 diabetes and coronary heart disease, as well as the incidence of several cardiovascular risk factors.
The first study to evaluate sex differences in academic ranking among academic cardiologists has found that women were significantly less likely than men to be full professors, even when adjusting for factors such as age, years of experience and research productivity that are traditionally associated with academic rank.
Northeastern psychology professor Lisa Feldman Barrett and her colleagues at Massachusetts General Hospital have found that the neurotransmitter dopamine is involved in human bonding, bringing the brain’s reward system into our understanding of how we form human attachments.
Daylight savings time contributes to higher miscarriage rates among women undergoing in vitro fertilization who had had a prior pregnancy loss, according to a new study.
Massachusetts General Hospital investigators have developed a novel approach to analyze brainwaves during sleep, which promises to give a more detailed and accurate depiction of neurophysiological changes than provided by a traditional sleep study.
The effects of a promising new approach to chemotherapy that involves frequent administration of dosage levels much lower than traditionally used appears to rely on the “normalization” of blood vessels within and around a tumor.
Researchers from Weill Cornell Medicine and Massachusetts General Hospital will be conducting a clinical trial to investigate the ability of phenformin – a drug once used to treat diabetes – to improve the results of melanoma treatment.
The executive order restricting individuals from seven Muslim-majority countries from entering the U.S. is “a step backward” for medical education, patient care and biomedical research in this country, write medical department leaders from Massachusetts General Hospital and six other major academic medical centers.
A nearly two-decades-long clinical trial has demonstrated that adding antiandrogen therapy to radiation therapy can improve the survival of prostate cancer patients who have evidence of disease recurrence after radical prostatectomy.
Massachusetts General Hospital investigators report a naturally occurring hormone that plays an important role in fetal development may be the basis for a new type of reversible contraceptive that can protect ovaries from the damage caused by chemotherapy drugs.
A team led by a MassGeneral Hospital for Children physician has developed an assessment that may reduce the need for sleep studies in ruling out the presence of obstructive sleep apnea in people with Down syndrome.
Using a better form of gene therapy, scientists from Harvard Medical School and Massachusetts General Hospital have managed to restore partial hearing and balance in mice born with a genetic condition that affects both.
Using a novel PET radiotracer, a team of Massachusetts General Hospital researchers has found a way to quantify olfactory sensory neurons and thus improve measurements of olfactory health, a reliable marker of the health of the brain.
Using a novel approach for imaging the movement of immune cells in living animals, researchers from the Massachusetts General Hospital Center for Immunology and Inflammatory Diseases have identified what appear to be the initial steps leading to joint inflammation in a model of inflammatory arthritis.
Massachusetts General Hospital investigators describe how use of an advanced form of the commonly used polymerase chain reaction method to analyze circulating tumor cells may greatly increase the ability to diagnose early-stage cancer, increasing the likelihood of successful treatment.
Public health experts from Massachusetts General Hospital and the Harvard T.H. Chan School of Public Health applaud the efforts of the U.S. Department of Housing and Urban Development to protect public housing residents from the harmful effects of tobacco exposure and discuss both implementation challenges and possible solutions to ease the burden of transition.
A Massachusetts General Hospital study finds reduced expression of genes involved in the integrity of the blood-brain barrier and the intestinal barrier in those with autism spectrum disorder.
Investigators at Massachusetts General Hospital have found new evidence that the tumor necrosis factor receptor type II may be a major target for immuno-oncology treatments, which induce a patient's immune system to fight cancer.
Massachusetts General Hospital investigators have identified a protein that may play an essential role in maintaining a population of tumor-initiating cells (TICs)—treatment-resistant cells responsible for cancer recurrence and metastasis—in breast cancer, as well as a compound that appears to reduce the molecule’s ability to protect TICs from the effects of chemotherapy. Results of the team’s study are being published online in PNAS.
A survey conducted by investigators at the Mongan Institute Health Policy Center at Massachusetts General Hospital (MGH) found that almost one-third of Californians enrolling in individual insurance plans offered under the Affordable Care Act (ACA) in 2014 potentially missed opportunities to receive financial assistance with either premium payments, out-of-pocket costs or both. In their report published in the journal Health Affairs, the researchers note that enrollees who received assistance from certified enrollment counselors were less likely to choose plans that made them ineligible for assistance.
