A bacteria typically linked to periodontal disease, Fusobacterium nucleatum (F. nuc), could play an important role in the rising incidence of colorectal cancer in people under the age of 45. Another type of bacteria, Moraxella osloensis, has been found in colorectal cancer tumors at a nearly four-fold higher rate in people over 75 than in those under 45 years of age, pointing out how differences in the bacteria that comprise what is known as the body’s microbiome could affect cancer outcomes to varying degrees.
These are the preliminary findings of an ongoing study that will be presented at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium in San Francisco from January 23-25, 2020.
Mice given a new drug targeting a key gene involved in lipid and glucose metabolism could tolerate a high-fat diet regimen (composed of 60% fat from lard) without developing significant liver damage, becoming obese, or disrupting their body’s glucose balance.
Adding a medication used to treat epilepsy, bipolar disorder and migraines to a blood pressure medicine reversed some aspects of breast cancer in the offspring of mice at high risk of the disease because of the high fat diet fed to their mothers during pregnancy. Conversely, this treatment combination increased breast cancer development in the offspring whose mothers had not been fed a high fat diet during pregnancy.
A clinical trial investigating the repurposed cancer drug nilotinib in people with Parkinson’s disease finds that it is reasonably safe and well tolerated. Researchers also report finding an increase in dopamine, the chemical lost as a result of neuronal destruction, and a decrease in neurotoxic proteins in the brain among study participants. Finally, they say nilotinib, a tyrosine kinase inhibitor, potentially halts motor and non-motor decline.
Brain imaging of veterans with Gulf War illness show varying abnormalities after moderate exercise that can be categorized into two distinct groups — an outcome that suggests a more complex illness that previously thought.
When FDA approved palbociclib (Ibrance ®), there was very little data about the safety of this drug in people with benign ethnic neutropenia (BEN), which is common in women of color. Some of these women didn’t qualify for the clinical trials because of the required blood count, which is lower in women with BEN.
Prior to an Alzheimer’s diagnosis, a person in the early stages of the disease faces a heightened risk of adverse financial outcomes — a likely consequence of compromised decision making when managing money, in addition to exploitation and fraud by others.
Gulf War Illness (GWI) and chronic fatigue syndrome (CFS) share symptoms of disabling fatigue, pain, systemic hyperalgesia (tenderness), negative emotion, sleep and cognitive dysfunction that are made worse after mild exertion (postexertional malaise). Now, neuroscientists at Georgetown University Medical Center have evidence, derived from human brain studies, that GWI and CFS are two distinct disorders that affect the brain in opposing ways.
Georgetown neuroscientists say they have identified how people can have a “crash in visual processing” — a bottleneck of feedforward and feedback signals that can cause us not to be consciously aware of stimuli that our brain recognized.
Neuroscientists at Georgetown University Medical Center say they have developed and tested an agent that reduces the buildup of toxic proteins in animal models of both Parkinson’s and Alzheimer’s diseases, and improves cognitive and motor behavior.
Human-made toxic chemicals that linger indefinitely in the environment disrupt the performance of critical helper cells in the mouse brain, leading to impaired function over long-term exposures.
Women with an aggressive, less-common type of breast cancer, known as triple-negative, versus a more common form of the disease, could be differentiated from each other by a panel of 17 small RNA molecules that are directly influenced by genetic alterations typically found in cancer cells.
New brain imaging research debunks a controversial theory about dyslexia that can impact how it is sometimes treated. The cerebellum, a brain structure traditionally considered to be involved in motor function, has been implicated in the reading disability, developmental dyslexia, however, this “cerebellar deficit hypothesis” has always been controversial. The new research shows that the cerebellum is not engaged during reading in typical readers and does not differ in children who have dyslexia.
Georgetown University Medical Center, a Lewy Body Dementia (LBD) Association Research Center of Excellence, is now offering three clinical trials to study new treatments for LBD, a disease often confused with Parkinson’s and Alzheimer’s disease.
The pending deal for Altria to purchase 35% of Juul Labs should serve as a “wake-up call” for the careful monitoring of competition in the nicotine delivery market, and for evaluating how regulations and policies impact cigarette and non-cigarette firms selling alternative nicotine delivery products, says a Georgetown University professor.
Researchers have decoded a chain of molecules that are critical for the growth and survival of pancreatic ductal adenocarcinoma—the most common and also the most lethal form of pancreatic cancer.

Georgetown University Medical Center announces the launch of the only known therapeutic (disease modifying) clinical trial for Lewy body dementia, a neurological disorder that affects a million people in the United States for which there are no approved medications that modify the disease.
Cancer patients previously excluded and underrepresented in immunotherapy clinical trials, such as African Americans and patients with HIV or viral hepatitis, actually benefit at the same rate as patients tested in the clinical trials, according to a Georgetown-led study to be presented at the 2019 ASCO Annual Meeting in Chicago.
A survey conducted by Georgetown investigators found a significant knowledge and practice gap among community oncologists in the understanding and usage of genetic testing in determining patients' treatment plans and potential clinical trial outcomes.
According to scientists who study women infected with HIV, statistics often paint an impressionist view of the lives of these women that misses the granular detail that tells the real story. The imprecise big picture is that most of this population is doing a good job at suppressing the virus, but facts gathered on the ground show that many struggle with issues of daily living that can make taking a pill to keep HIV at bay difficult.
As many as 90 percent of individuals who have a parent with Huntington’s disease (HD) choose not to take a gene test that reveals if they will also develop the fatal disorder — and a new study details the reasons why. Understanding the “why” matters as new clinical trials testing therapies for people who haven’t yet developed symptoms of Huntington disease requires participants to be tested for the HD gene to be included in the trials.
A new study suggests that Oncotype DX-guided treatment could reduce the cost for the first year of breast cancer care in the U.S. by about $50 million (about 2 percent of the overall costs in the first year). The study by Georgetown Lombardi Comprehensive Cancer Center and National Cancer Institute researchers was published April 24, in JNCI.
Despite a mandate to help patients make better-informed health care decisions, a ten-year research program established under the Affordable Care Act has funded a relatively small number of studies that examine primary care, the setting where the majority of patients in the U.S. receive treatment.
Georgetown University Medical Center (GUMC) announces the appointment of Deus Bazira, DrPH, MPH, MBA, BPharm, an expert in health systems strengthening and a public health practitioner with decades of in-depth field level practical experience in global health in emerging economies, to establish and co-direct Georgetown’s new Center for Global Health Practice and Impact (CGHPI).

Direct-to-consumer DNA testing kits are expected to be a popular holiday gift this year, with 100 million people expected to have used one by 2020—but an expert genetic counselor at Georgetown says consumers should understand a few pros and cons before using one.
The low unemployment rate in the U.S. — which fell to a 49 year-low in September and October — is good news to many people, but perhaps not to residents of nursing homes. A Georgetown University Medical Center study found that quality of care in nursing homes improves during periods of recession and worsens when the economy is good.
