Key takeaways  Decreasing trend in opioid prescriptions: There was a notable nationwide reduction in opioid prescriptions after surgery from 2013 to 2017, reflecting a shift in the medical community's approach to pain management.  Social determinants affect opioid prescription rates: At the county level, lower median population age, higher education levels, insufficient sleep, higher health care costs, fewer mental health providers, and higher uninsured rates are linked to higher opioid prescription rates.  No ...

Staphylococcus aureus (SA) is an extremely common bacterial infection; about 30% of people have colonies of SA living in their nose. SA is often harmless, but it is also a leading cause of hospital-acquired and community-associated infections. A vaccine for SA would be a game-changer for public health, but for decades, all vaccine candidates for SA have failed in clinical trials despite successful preclinical studies in mice. Researchers at University of California San Diego School of Medicine have finally explained why. In a new study, published January ...

About The Study: The findings of this study of U.S. families receiving employer-sponsored health insurance suggest that three decades of increasing health care premiums were likely associated with reduced annual earnings and increased earnings inequality by race and ethnicity and wage level and were meaningfully associated with wage stagnation.  Authors: Kurt Hager, Ph.D., M.S., of the UMass Chan Medical School in Worcester, Massachusetts, is the corresponding author.   To access the embargoed ...

About The Study: The results of this survey study involving 4,119 currently competing U.S. college athletes suggest that interpersonal violence is associated with marked changes in the psychosocial health and emotional well-being of college athletes, particularly those who identify as female and with non-heterosexual sexual orientations. Variations in coaching style have the potential to alter these associations. Ongoing efforts are needed to leverage the unique position that coaches hold to help reduce interpersonal violence and create safe places where all college athletes can thrive.  Authors: Yetsa A. Tuakli-Wosornu, M.D., ...

PHILADELPHIA – Ordering a palliative care consultation by “default” – via an automatic order programmed into the electronic medical record that doctors may cancel if they choose – is an effective strategy to give more hospitalized patients the opportunity to benefit from palliative care, and sooner, according to a new study led by researchers from the Perelman School of Medicine at the University of Pennsylvania. Palliative care is specialized medical care focused on relieving the symptoms and stress of a serious illness and improving quality of life, in alignment with a patient’s ...

The rising cost of health insurance is an ongoing concern in the United States. New research shows that increasing health insurance costs are eating up a growing proportion of worker’s compensation, and have been a major factor in both flattening wages and increasing income inequality over the past 30 years.  In a study from the Friedman School of Nutrition Science and Policy at Tufts University, researchers found that the cost of employer-sponsored insurance (ESI) health care benefits increased much faster than workers’ wages since the late 1980s, ...

AURORA, Colo. (January 16, 2024) – Researchers from the University of Colorado Anschutz Medical Campus have found that a team intervention, provided by phone, leads to persistent improvements in depression, anxiety, and quality of life for people managing chronic illnesses. Additionally, researchers found that the improvement in quality of life results last months after intervention concludes. In a study, published today in JAMA, researchers observe the impact a telecare intervention program, called ADAPT, has on veterans suffering from poor quality of life as a result ...

An experiment outlined by a UCL (University College London)-led team of scientists from the UK and India could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale than that of particles and atoms. Quantum theory is typically seen as describing nature at the tiniest scales and quantum effects have not been observed in a laboratory for objects more massive than about a quintillionth of a gram, or more precisely 10^(-20)g. The new experiment, described in a paper published in Physical Review Letters and involving researchers at UCL, the University of Southampton and ...

Neuroscientists from the University of Vienna and the Karolinska Institute in Stockholm have investigated whether playing violent video games leads to a reduction in human empathy. To do this, they had adult test subjects play a violent video game repeatedly over the course of an experiment lasting several weeks. Before and after, their empathic responses to the pain of another person were measured. It was found that the violent video game had no discernible effect on empathy and underlying brain activity. These results have now been published in the renowned journal eLife. Video games have become an integral part of the everyday life of many ...

WASHINGTON (Jan. 16, 2024) – Artificial intelligence (AI) has the potential to detect rheumatic heart disease (RHD) with the same accuracy as a cardiologist, according to new research demonstrating how sophisticated deep learning technology can be applied to this disease of inequity. The work could prevent hundreds of thousands of unnecessary deaths around the world annually.    Developed at Children’s National Hospital and detailed in the latest edition of the Journal of the American Heart Association, the new AI system combines the power of novel ultrasound probes with portable electronic ...

Knowing a patient’s weight is necessary for many weight-based medications such as thrombolytics, anticoagulants and numerous cardiovascular medications. Scaling drugs to a patient’s weight prevents adverse events from overtreatment and treatment failure due to underdosing. Inaccurate weight estimations may lead to inaccurate drug doses, which could cause patient harm.  However, in the emergency department (ED) during resuscitative care, measuring weight is often impossible. Moreover, little is known about the relative accuracy of different methods currently used to weigh patients during emergency care. For example, ...

TORONTO (16 January 2024) – As part of its pioneering approach to drug discovery, the Canadian nonprofit Conscience announced today that its first open science competition has resulted in the identification of seven promising molecules, or “hits,” that show potential for new, more effective drugs for familial Parkinson’s disease.  This first competition in Conscience’s CACHE (Critical Assessment of Computational Hit-Finding Experiments) Challenge series was funded by The ...

From inside an operating room in Barquisimeto, Venezuela, electrophysiologist Maria Milagros Arends, M.D., threads wires from a pacemaker through the veins and into the heart muscle of a patient.  This pacemaker, which regulates the heartbeat and can be lifesaving, was once in the body of another person. It has been recycled, or “reconditioned”— donated, tested, sterilized and shipped from the United States to the South American country for implantation.  “We have a waiting list of around 300 people who could potentially lose their lives in less than a month,” ...

CHAMPAIGN, Ill. — A new study links increased use of acetaminophen during pregnancy – particularly in the second trimester – to modest but noticeable increases in problems with attention and behavior in 2-, 3- and 4-year-olds.

The findings are detailed in the journal Neurotoxicology and Teratology. The research is part of the Illinois Kids Development Study at the University of Illinois Urbana-Champaign, which explores how environmental ...

Monoclonal antibodies (mAbs) are laboratory-designed proteins that mimic the immune system's antibodies. To date, many therapeutic mAbs belonging to the immunoglobulin G (IgG) class of antibodies, have been approved for the treatment of cancer and autoimmune diseases. Cell lines such as the Chinese hamster ovary (CHO) cells are generally used to produce mAbs. Notably, the production and manufacture of mAbs are regulated by critical quality attributes (CQAs) to ensure their safety and efficacy in treatment. An important CQA for mAbs is the N-linked glycosylation present at a specific position (Asn297). N-linked glycans consist of N-acetylglucosamine (GlcNAc), mannose (Man), fucose ...
