Scientists have developed a lung-on-chip model to study how the body responds to early tuberculosis (TB) infection, according to findings published today in eLife.
While there are therapies to aid in overall heart health, there are very few preventative therapies for heart failure after a significant heart attack, a serious condition that has a very significant mortality. However, researchers at Baylor College of Medicine have found a potential treatment that has shown promising results in mice.
COLUMBUS, Ohio - There's one group of essential workers who especially enjoy being called a "hero" during the COVID-19 pandemic: narcissists.
In a new study, researchers found that essential workers (including those in restaurants, grocery and retail stores) who scored higher on measures of narcissism shared more than others about their work. And this sharing on social media, in person and elsewhere increased their narcissistic feelings in the moment.
Our lungs are exposed to a multitude of hazardous airborne particles on a daily basis. Nanoparticles, due to their small size, may reach the sensitive alveolar region of the human lung and trigger inflammation even after a single inhalation leading to severe diseases such as heart disease, brain damage and lung cancer for prolonged exposure. In manufacturing, toxic nanoparticles may be released into the environment during the production, processing, degradation or combustion of materials.
UNIVERSITY PARK, Pa. -- Don't be afraid to toss a handful of raisins or dried apples in your Thanksgiving stuffing this year -- a new Penn State study has found that dried fruit may be connected with better health.
The researchers found that people who ate dried fruit were generally healthier than those who did not, and on days when people ate dried fruit they consumed greater amounts of some key nutrients than on days when they skipped. However, they also found that people consumed more total calories on days when they ate dried fruit.
Aurora, Colo. (Nov. 24, 2020) - Eighty to 90% of adolescents benefit from lasting weight loss following bariatric surgery, and most experience the remission of obesity-related complications such as elevated blood pressure, high cholesterol, type 2 diabetes and musculoskeletal pain, among others.
PHILADELPHIA (November 24, 2020) - In-hospital cardiac arrests (IHCA) represent catastrophic and often terminal events. Despite investments to improve the quality of resuscitation efforts, fewer than 25% of all patients that experience cardiac arrests in hospitals survive to discharge, and survival varies significantly across hospitals and by race. Until now, few have been able to specify reasons for the between-hospital differences.
A Cleveland Clinic study shows that among patients who have obesity and who tested positive for COVID-19, a past history of bariatric surgery was significantly associated with a lower risk of hospital and intensive care unit admission. The results were published in the journal of Surgery for Obesity and Related Diseases.
A research team at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan has succeeded in experimentally evolving the common bacteria Escherichia coli under pressure from a large number of individual antibiotics. In doing so, they were able to identify the mechanisms and constraints underlying evolved drug resistance. Their findings, published in the scientific journal Nature Communications, can be used to help develop drug-treatment strategies that minimize the chance that bacteria will develop resistance.
WEST LAFAYETTE, Ind. - The COVID-19 pandemic is leading a Purdue University innovator to make changes as she works to provide new options for people with Parkinson's disease.
Jessica Huber, a professor of Speech, Language, and Hearing Sciences and associate dean for research in Purdue's College of Health and Human Sciences, leads Purdue's Motor Speech Lab. Huber and her team are now doing virtual studies to evaluate speech disorders related to Parkinson's using artificial intelligence technology platforms.
Aortic stenosis is one of the most common heart valve defects. Its prevalence increases with age and it often requires treatment. As well as conventional valve replacement involving open-heart surgery, a less invasive procedure has now been available for some time in the form of transcatheter aortic valve replacement (TAVR). In this procedure, the new valve is implanted during a cardiac catheter examination. This minimally invasive procedure is an important treatment option, especially for older patients.
CHICAGO (November 23, 2020): The Affordable Care Act's Medicaid expansion for low-income people appears to lead to earlier diagnosis of colon cancer, enhanced access to care, and improved surgical care for patients with this common cancer, researchers report in a new study. The study is published as an "article in press" on the Journal of the American College of Surgeons website in advance of print.
Abnormally high blood sugar may worsen outcomes and mortality rates for COVID-19 patients, including those without diabetes, according to major research published in the peer-reviewed open access journal Annals of Medicine.
Researchers at Radboud university medical center have discovered an as yet unknown effect of hydroxychloroquine. It inhibits the action of a type of white blood cells important in the first line of defense against infections. Based on this research, hydroxychloroquine is unlikely to be beneficial in clearing viral infections including the new coronavirus SARS-CoV-2, they write in their publication in Cell Reports Medicine.
TROY, N.Y. - With communities across the nation experiencing a wave of COVID-19 infections, clinicians need effective tools that will enable them to aggressively and accurately treat each patient based on their specific disease presentation, health history, and medical risks.
