WASHINGTON--Women with obesity and polycystic ovarian syndrome (PCOS) are at increased risk of developing type 2 diabetes, according to a study presented virtually at ENDO 2021, the Endocrine Society's annual meeting. Normal-weight women with PCOS are not at increased risk, the researchers found. Women with PCOS had a more than three-fold increased risk of developing type 2 diabetes during their lifetime, the study found. This risk was evident only in women who met the criteria for overweight or obesity, but not in lean women. "We strongly suggest weight management in women with obesity and PCOS in an attempt to reduce this major risk of ...

WASHINGTON--Only 3% of patients at high risk for primary aldosteronism (PA), a common disorder that causes high blood pressure and can lead to heart and kidney complications, are screened for the condition, according to a study that will be presented virtually at ENDO 2021, the Endocrine Society's annual meeting. "The results of our study indicate that initiatives to encourage PA screening are crucial for preventing cardiovascular and kidney disease in many patients with hypertension," said lead researcher Seda Grigoryan, M.D., of Michigan State University in Lansing, Mich. PA is the most common form of secondary hypertension--high blood pressure caused by another disease. END ...

WASHINGTON--A lifestyle intervention targeting women with obesity and infertility is more effective in increasing the pregnancy rate compared with fertility treatments, according to a study presented virtually at ENDO 2021, the Endocrine Society's annual meeting. The lifestyle intervention, called the Fit-For-Fertility (FFF) program, is a cost-effective alternative to the usual standard of care for women with obesity seeking fertility treatments, according to lead researcher Matea Belan, Ph.D., of the University of Sherbrooke and the Research Center of the Centre Hospitalier Universitaire de Sherbrooke (RC-CHUS) in Quebec, Canada. "Our study shows that the FFF program can significantly improve the pregnancy rate, especially the spontaneous pregnancy ...

WASHINGTON--Transgender youth have higher odds than cisgender youth of being diagnosed with medical conditions that can affect their overall metabolic and cardiovascular health, according to a study presented virtually at ENDO 2021, the Endocrine Society's annual meeting. The study included 4,174 youth with a diagnosis of gender dysphoria, a term for a deep sense of unease and distress that may occur when a person's gender identity does not match their sex designated at birth. An estimated 1.8% of adolescents identify as transgender, according to lead researcher Anna Valentine, M.D., of the University of Colorado Anschutz Medical ...

WASHINGTON--Patients with low vitamin D levels who are hospitalized for COVID-19 may have a lower risk of dying or requiring mechanical ventilation if they receive vitamin D supplementation of at least 1,000 units weekly, according to a study presented virtually at ENDO 2021, the Endocrine Society's annual meeting. "Given how common vitamin D deficiency is in the world and the United States, we believe that this research is highly relevant right now," said co-author Sweta Chekuri, M.D., of Montefiore Health System and Albert Einstein College of Medicine in the Bronx, New York. Research has shown that vitamin D supplementation can prevent inflammation in other respiratory diseases, but there have been limited studies examining the role of vitamin D supplementation in COVID-19. ...

WASHINGTON--Black women with polycystic ovary syndrome (PCOS) have higher risk factors for heart disease, diabetes and stroke compared with white women, according to a study presented virtually at ENDO 2021, the Endocrine Society's annual meeting. PCOS is a common disorder characterized by irregular menstrual periods, disruption of normal metabolism and excessive hair growth. PCOS affects up to 10% of all women of reproductive age. The disorder increases the risk for health conditions including infertility, obesity, heart disease, type 2 diabetes, depression and certain ...

WASHINGTON--In adults with obesity or overweight, weekly treatment with the glucagon-like peptide 1 (GLP1) receptor agonist semaglutide leads to reduced excess body fat and increased lean body mass, according to an industry-sponsored study presented virtually at ENDO 2021, the Endocrine Society's annual meeting. "Our findings suggest that semaglutide, through body weight loss and improvement of body composition, has the potential to reduce the risk of heart disease, diabetes and stroke in people with overweight or obesity," said lead researcher John Wilding, D.M., F.R.C.P., of the University of Liverpool. Obesity poses many health risks. Excess fat in the abdominal area, particularly ...

WASHINGTON--Patients hospitalized with COVID-19 have worse outcomes if they have high blood sugar, or hyperglycemia, regardless of whether they have diabetes, a new study finds. The researchers will present their results, of the first known study of the impact of hyperglycemia on a largely Black patient population with the novel coronavirus, at ENDO 2021, the Endocrine Society's annual meeting. The investigators found that patients with COVID-19 who had hyperglycemia on admission to the hospital were more likely than those with normal glucose (sugar) to require a breathing machine or admission to the intensive care unit (ICU). These patients also were reportedly likelier to have kidney injury and to die ...

WASHINGTON--More patients than previously reported may experience hearing symptoms such as hearing loss or muffled hearing from a new treatment for thyroid eye disease, teprotumumab (Tepezza), according to a small study presented virtually at ENDO 2021, the Endocrine Society's annual meeting. Teprotumumab, approved by the U.S. Food and Drug Administration in January 2020, is the first and only drug to be approved for thyroid eye disease. In two clinical trials conducted prior to FDA approval of the drug, otologic symptoms were reported in 10 percent of patients. The new study found the rate could be as high as 65 percent. The treatment is administered to patients once every three weeks for a total of eight infusions. It ...

WASHINGTON--People with type 1 diabetes can improve their blood sugar control while reducing time with low blood sugar, or hypoglycemia, using Insulet Corporation's Omnipod 5 Automated Insulin Delivery System compared to their standard insulin therapy. Results from an industry-sponsored study of the latest Omnipod, the first tubeless, wearable insulin pump, will be presented at ENDO 2021, the Endocrine Society's annual meeting. The Omnipod 5 System underwent three months of at-home testing in 128 adults and adolescents ages 14 to 70 years and 112 children ages 6 to less than 14 years. All study participants have type 1 diabetes and were first followed for two weeks using their standard therapy, either multiple daily insulin injections ...

WASHINGTON--Higher levels of the stomach-derived hormone ghrelin, which stimulates appetite, predict a greater preference for smaller immediate monetary rewards over larger delayed financial rewards, a new study finds. The study results will be presented at ENDO 2021, the Endocrine Society's annual meeting. This research presents novel evidence in humans that ghrelin, the so-called "hunger hormone," affects monetary decision making, said co-investigator Franziska Plessow, Ph.D., assistant professor of medicine at Massachusetts General Hospital and Harvard Medical School, Boston. She said recent research findings in rodents suggested that ghrelin may play a part in impulsive choices and behaviors. "Our results indicate that ghrelin might play a broader role than ...

WASHINGTON--Nearly one in five U.S. children and teenagers has obesity, and statistics show a higher prevalence of obesity in certain ethnicities, such as Hispanics and Blacks. Now results of a study being presented at ENDO 2021, the Endocrine Society's annual meeting, suggest that Spanish as a family's primary language is a predictor of childhood obesity, regardless of ethnicity. The prevalence of obesity among children and teens from Spanish-speaking households in the nation was 24.4 percent, approximately 50 percent higher than those from English-speaking households, according to results of a new analysis of the U.S. National Health and Nutrition Examination Survey. This survey examines a nationally representative sample ...

Choice Architecture Compensates for Low Consumer Knowledge" and is authored by Kellen Mrkva, Nathaniel Posner, Crystal Reeck, and Eric Johnson. As Mrkva explains, "Our research demonstrates that people with low socioeconomic status (SES), low numerical ability, and low knowledge are most impacted by nudges. As a result, 'good nudges,' designed to encourage ...

It's estimated that an average-sized wastewater treatment plant serving roughly 400,000 residents will discharge up to 2,000,000 microplastic particles into the environment each day. Yet, researchers are still learning the environmental and human health impact of these ultra-fine plastic particles, less than 5 millimeters in length, found in everything from cosmetics, toothpaste and clothing microfibers, to our food, air and drinking water. Now, researchers at New Jersey Institute of Technology have shown that ubiquitous microplastics can become 'hubs' for antibiotic-resistant bacteria ...

ROCHESTER, Minn. -- Low representation of minority groups in public genomic databases may affect therapy selection for Black patients with cancer, according to new Mayo Clinic research published in npj Precision Oncology. The researchers investigated the use of genomic databases and found that tumor mutation burden was significantly inflated in Black patients compared to White patients. As a result of the study, clinicians who are using public genomic databases need to be aware of the potential for inflated tumor mutation burden values and how that may affect therapy selection and outcomes, especially for patients from underrepresented groups. Clinicians use biomarkers, which are indicators of a disease or condition, to determine ...

BOSTON - Researchers have used a genetic engineering strategy to dramatically reduce levels of tau--a key protein that accumulates and becomes tangled in the brain during the development of Alzheimer's disease--in an animal model of the condition. The results, which come from investigators at Massachusetts General Hospital (MGH) and Sangamo Therapeutics Inc., could lead to a potentially promising treatment for patients with this devastating illness. As described in Science Advances, the strategy involves a gene regulation technology called zinc finger protein transcription ...

In a world first, a cross-institutional research collaboration has used a two-photon microscope (*1) with a combination of calcium imaging (*2) and holographic stimulation (*3) to reveal that the functional connectivity between neurons located in the primary somatosensory cortex is increased in response to acute pain. Pain occurs as a result of injury, such as peripheral neuron damage or inflammation stemming from peripheral tissue violation. Research findings have been published on the involvement of central nervous system abnormalities in the onset of pain and sustained pain. The primary somatosensory cortex ...

COLUMBUS, Ohio - Most stroke victims don't receive treatment fast enough to prevent brain damage. Scientists at The Ohio State University Wexner Medical Center, College of Engineering and College of Medicine have developed technology to "retrain" cells to help repair damaged brain tissue. It's an advancement that may someday help patients regain speech, cognition and motor function, even when administered days after an ischemic stroke. Engineering and medical researchers use a process created by Ohio State called tissue nanotransfection (TNT) to introduce genetic material into cells. This allows them to reprogram skin cells to become something ...

New York, NY--March 19, 2020--Columbia Engineering researchers, working with Brookhaven National Laboratory, report today that they have built designed nanoparticle-based 3D materials that can withstand a vacuum, high temperatures, high pressure, and high radiation. This new fabrication process results in robust and fully engineered nanoscale frameworks that not only can accommodate a variety of functional nanoparticle types but also can be quickly processed with conventional nanofabrication methods. "These self-assembled nanoparticles-based materials are so resilient that they could fly in space," says Oleg Gang, professor ...

PITTSBURGH, March 19, 2021 - Non-circulating memory T cells, whose main function is to provide local protection against re-infection, contribute to chronic transplant rejection, University of Pittsburgh School of Medicine researchers reveal in a paper published today in Science Immunology. The scientists show that these "tissue-resident memory T cells" are harmful in situations where antigens that the cells recognize are present in the body for a long time, such as in cases of an organ or tissue transplant. This finding is an important step toward improving therapies to help prevent organ rejection in transplant recipients. "Tissue-resident memory T cells serve an important surveillance function," said co-senior author Martin Oberbarnscheidt, ...

CAMBRIDGE, MA -- Many viruses infect their hosts through mucosal surfaces such as the lining of the respiratory tract. MIT researchers have now developed a vaccination strategy that can create an army of T cells that are ready and waiting at those surfaces, offering a quicker response to viral invaders. The researchers showed that they could induce a strong memory T cell response in the lungs of mice by giving them a vaccine modified to bind to a protein naturally present in mucus. This can help ferry the vaccine across mucosal barriers, such as the lining of the lungs. "In this paper, we specifically focused on T cell responses that would be useful against viruses or cancer, and our idea was to use this protein, albumin, as sort of a Trojan horse to ...

To understand the fundamental properties of an industrial solvent, chemists with the University of Cincinnati turned to a supercomputer. UC chemistry professor and department head Thomas Beck and UC graduate student Andrew Eisenhart ran quantum simulations to understand glycerol carbonate, a compound used in biodiesel and as a common solvent. They found that the simulation provided detail about hydrogen bonding in determining the structural and dynamic properties of the liquid that was missing from classical models. The study was published in the Journal of Physical Chemistry B. Glycerol carbonate could be a more environmentally ...

During a public health crisis like the COVID-19 pandemic, U.S. hospitals need to allocate scarce medical resources in an equitable manner, according to clinicians and ethicists at the University of Miami Miller School of Medicine. "Significant concerns have been raised that crisis standards of care may be biased against certain patients based on race or ethnicity," said Hayley Gershengorn, M.D., associate professor of pulmonary and critical care medicine. "To examine that issue, we analyzed over a thousand medical records from two academic hospitals where University of Miami faculty see patients and found no disparities ...
