LOS ANGELES — More than 660 Nevadans need an organ transplant, according to Nevada Organ Network, a federally designated organ procurement organization; but many currently struggle to access care because of limited transplant services available in Nevada.   Amid the growing need for additional transplant services in the state, Keck Medicine of USC has opened a new location in Las Vegas that will provide specialized care for patients in Las Vegas and surrounding communities who need a liver or heart transplant.   The clinic is the first in Nevada to offer ...

Chemokines are signalling proteins that orchestrate the interaction of immune cells against pathogens and tumours. To understand this complex network, various techniques have been developed to identify chemokine-producing cells. However, it has not yet been possible to determine which cells react to these chemokines. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have developed a new class of genetically modified mice that enables the simultaneous identification of chemokine producers and sensors. Using the chemokine ...

Kingston, ON, March 27, 2024 – In the era after the introduction of publicly funded in vitro fertilization (IVF) mandating elective single embryo transfer, the multifetal pregnancy rate decreased significantly for IVF, but the contribution of ovulation induction and intrauterine insemination (OI/IUI) to multifetal pregnancy still needs attention, according to a new study from ICES and Queen’s University.  Twins, triplets, and higher multifetal pregnancies are associated with some adverse outcomes ...

A new study led by researchers at the American Cancer Society (ACS) showed people surviving cancer who reported feeling more lonely experienced a higher mortality risk compared to survivors reporting low or no loneliness. Researchers observed the highest mortality risk among the group reporting the highest levels of loneliness, even after adjusting for sociodemographic characteristics. The findings are published today in the Journal of the National Comprehensive Cancer Network (JNCCN). “Loneliness, ...

About The Study: In this nationally representative cross-sectional study of 25,000 participants, those experiencing post–COVID-19 condition (PCC) were approximately twice as likely to report depression and anxiety symptoms than other U.S. adults. Among individuals with these symptoms, adults with PCC were just as likely to have received mental health treatment but more likely to report cost-related barriers to accessing therapy. Care pathways for PCC should consider prioritizing mental health screening and affordable treatment.  Authors: Hiten Naik, M.D., ...

About The Study: In an otherwise largely homogeneous sample of female nurses, participants identifying as lesbian or bisexual had markedly earlier mortality during the study period compared with heterosexual women. These differences in mortality timing highlight the urgency of addressing modifiable risks and upstream social forces that propagate and perpetuate disparities.  Authors: Sarah McKetta, M.D., Ph.D., of Harvard University in Boston, is the corresponding author. To access the embargoed ...

Warning letters from Medicare can safely cut prescribing of a powerful but risky antipsychotic, according to a new study at Columbia University Mailman School of Public Health. Researchers used Medicare data to study the effects of the letters on hundreds of thousands of older adults with dementia. They found a significant and lasting reduction in prescribing but no signs of adverse effects on patient health. The findings are published in JAMA Network Open. “Our study shows that low-cost letter interventions can safely reduce antipsychotic prescribing to patients with dementia,” said Adam Sacarny, PhD, assistant professor of Health Policy and Management at Columbia Mailman School. ...

Key takeaways: A new study led by the Harvard Pilgrim Health Care Institute examined differences in premature mortality by sexual orientation among a large group of women followed for three decades. Findings show that sexual minority women died much sooner than heterosexual women, with bisexual women having the most pronounced differences. This work highlights the urgent need to address sexual orientation-related inequities in preventable illness, including a focus on the systems and laws that ...

Due to the changing climate, young herring arrive in the Wadden Sea earlier and earlier in spring. That is shown in a new publication by NIOZ ecologists Mark Rademaker, Myron Peck and Anieke van Leeuwen, in this month's journal Global Change Biology. "The fact that we were able to demonstrate this, was only due to very consistently, for more than 60 years, and continuously sampling the fish every spring and every fall with exactly the same fyke every time", Rademaker says. "Recognizing this kind of change requires extreme precision ...

NEW YORK, NY--If mice ever wonder what it’s like to experience the world as a rat, some are now able to live that dream, at least when it comes to the sense of smell.  Researchers led by Columbia University's Kristin Baldwin have created mice with hybrid brains – part mouse, part rat – that sense the odors of the world with their rat neurons.   It is the first time that an animal has been able to use the sensory apparatus of another to sense and respond accurately to the world ...

Following the 2017 siege of Marawi, the Philippines' counter-terrorism efforts have faced an increasingly complex and unpredictable landscape.

WASHINGTON — Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D images with a low-power laser. This advance could make single-photon lidar practical for air and space applications such as environmental monitoring, 3D terrain mapping and object identification. Single-photon lidar uses single-photon detection techniques to measure the time it takes laser pulses to travel to objects and back. It is particularly useful for airborne applications because it enables highly accurate 3D mapping of terrain and objects even in challenging environments such as dense vegetation or urban areas. “Using single-photon ...

(WASHINGTON, April 25, 2024) – The volume of hematopoietic cell transplants rose among all racial/ethnic groups, but grew faster among African Americans and Hispanics compared with Non-Hispanic white individuals, mirroring changes in population growth rates. Survival after both autologous hematopoietic cell transplant (autoHCT) and allogeneic hematopoietic transplant (alloHCT) improved over time across racial/ethnic groups, though non-Hispanic African Americans still have worse outcomes, according ...

INDIANAPOLIS – Chlamydia and gonorrhea are the two most common sexually transmitted infections (STIs) in the United States, impacting 2.4 million in 2021, and the number is rising. A recent study of individuals ages 15 to 60 measuring and comparing treatment rates for these STIs has found that nearly one-in-five patients with chlamydia and one-in-four patients with gonorrhea did not receive Centers for Disease Control and Prevention (CDC) recommended treatment for their infection. Individuals seen by clinicians in a private healthcare setting were less likely to receive CDC recommended treatment than those seen ...

Plastic is a very complex material that can contain many different chemicals, some of which can be harmful. This is also true for plastic food packaging. “We found as many as 9936 different chemicals in a single plastic product used as food packaging,” said Martin Wagner, a professor at the Norwegian University of Science and Technology (NTNU’s) Department of Biology.

Thermal barrier coatings (TBCs) are widely used in gas turbine engines to obtain elevated working temperatures and improve engine efficiency. The phase transition of the ceramic layer is accompanied by a large volume difference, causing the concentration of thermal stress, eventually leading to TBCs to fall off and fail. Therefore, it is necessary to quantitatively evaluate the magnitude and distribution of thermal stress induced by phase transition in the ceramic layer.   A team of material scientists led ...

A new study published in the journal Animal-Human Interactions reveals that emotional turmoil experienced by dog owners after their pet has been stolen is like that of losing a loved one such as a caregiver losing their child. The findings empirically support the notions that the ‘owner’ or guardian roles and relationships equate to familial relationships and, when faced with the theft of their pet, owners feel a similar sense of disenfranchised grief and ambiguous loss. In the study, some participants felt the loss was more intense ...
