New research published in Headache reveals that, in children and adolescents, pain in the lower limbs—what are often called “growing pains” by clinicians and are commonly attributed to rapid growth—may indicate the presence or risk of migraines. The study included 100 children and adolescents born to mothers with migraines seen at a headache clinic, with half of the youth experiencing growing pains. “In families of children with growing pains, there is an increased prevalence of other pain syndromes, especially migraine ...

New research published in the Journal of the American Geriatrics Society indicates that antipsychotics are likely overprescribed and used inappropriately among patients with Alzheimer’s disease and related dementias (ADRD) receiving home health care, and such use is linked to worse patient outcomes. Antipsychotic drugs are not approved for the treatment of dementia—they are mostly used off-label to manage the symptoms that many people with ADRD experience, such as agitation, aggression, and psychosis that are called “behavioral and psychological symptoms of dementia.” In addition, ...

Osaka, Japan – As cute as raccoons may look, their behaviors are troublesome, and so are their droppings. Known to contain Escherichia albertii—a harmful enteropathogen—raccoon feces challenge zoonotic researchers who grapple to isolate this bacterium for further study. Fortunately, Osaka Metropolitan University scientists have come up with a novel culture medium for efficient isolation of E. albertii, making progress toward alleviating this particular raccoon-conveyed threat. Due ...

WASHINGTON (September 6, 2023) – An annual survey of physical and sexual violence suffered by Californians documents for the first time the higher incidence of violence among non-binary and transgender people. One in 20 California adults has experienced physical violence (5%) in the past year, a decrease from 8% in 2022, according to The California Violence Experiences Study (CalVEX); but the reported rates for non-binary and transgender individuals were notably higher, 14% and 27%, respectively. “The new data we have in this year’s report show that rates of violence have declined since levels seen during the pandemic, but these experiences remain too ...

SALT LAKE CITY, Sept. 6, 2023 – Myriad Genetics, Inc. (NASDAQ:MYGN), a leader in genetic testing and precision medicine, today revealed new nationwide survey results indicating widespread confusion and misconceptions about ovarian cancer screening among a majority of women.  The Myriad Genetics Cancer Risk survey shows that nearly three out of four women (71%) falsely believe annual pap smears include testing for ovarian cancer. According to the Centers for Disease Control and Prevention (CDC), the “only gynecologic cancer the Pap test screens for is cervical cancer.” “Ovarian cancer is ...

Non-Hermitian systems with their spectral degeneracies known as exceptional points (EPs) have been explored for lasing, controlling light transport, and enhancing a sensor’s response. A ring resonator can be brought to an EP by controlling the coupling between its frequency degenerate clockwise and counterclockwise traveling modes. This has been typically achieved by introducing two or more nano-tips into the resonator’s mode volume. While this method provides a route to study EP physics, the basic understanding of how the nano-tips’ shape and size symmetry impact the system’s non-Hermicity is missing, along with additional loss from both in-plane and out-of-plane ...

There’s been a striking 79% increase in new cases of cancer among the under 50s around the world over the past three decades (1990-2019), finds research published today in the open access journal BMJ Oncology. Breast cancer accounted for the highest number of ‘early onset’ cases in this age group in 2019. But cancers of the windpipe (nasopharynx) and prostate have risen the fastest since 1990, the analysis reveals. Cancers exacting the heaviest death toll and compromising health the most among younger adults in 2019 were those of the breast, windpipe, lung, bowel, and stomach. The findings ...

There’s strong evidence of a ‘threshold effect’ in English hospitals’ efforts to comply with the 18-week referral to treatment standard, concludes a long term data analysis of performance against the target, published online in the journal BMJ Quality & Safety. The target focused activity on meeting the threshold requirement for patients on the waiting list after which it tailed off—the so-called threshold effect–rather than instigating pervasive improvement in practice, the analysis indicates. Clinical need may be a secondary consideration for meeting the target, suggest the researchers. In 2012, an 18-week ...

The hyperactivity disorder, usually referred to as ADHD, is an independent risk factor for several common and serious mental health issues, finds research published in the open access journal BMJ Mental Health. It is associated with major depression, post traumatic stress disorder, the eating disorder anorexia nervosa, and suicide attempts, the findings show, prompting the researchers to recommend vigilance by health professionals in a bid to ward off these disorders later on. Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition in children and teens that extends into adulthood in up to around two thirds of cases. Worldwide, its prevalence ...

The rotating shoulders and extending elbows that allow humans to reach for a high shelf or toss a ball with friends may have first evolved as a natural braking system for our primate ancestors who simply needed to get out of trees without dying. Dartmouth researchers report in the journal Royal Society Open Science that apes and early humans likely evolved free-moving shoulders and flexible elbows to slow their descent from trees as gravity pulled on their heavier bodies. When early humans left forests for the grassy savanna, the researchers say, their versatile appendages were essential ...

Limestone spheroids, enigmatic lithic artifacts from the ancient past, have perplexed archaeologists for years.

Across the globe, and particularly in Brazil, lies an embarrassment of riches that also stage a showdown as mitigating climate change and protecting biodiversity square off against growing food. In this week’s Science of the Total Environment, scientists from and once affiliated with Michigan State University’s Center for Systems Integration and Sustainability (MSU-CSIS) identify ways for landowners in rural areas to be able to capitalize on win-win situations, whether they have fruitful land ...

Among 2,055 adults with a wide range of glomerular diseases, the COVID-19 vaccination did not adversely affect kidney function or worsen kidney damage and appeared safe in this population. Patients with glomerular disease (GN) may be at increased risk of severe COVID-19, yet concerns over vaccines causing disease relapse may lead to vaccine hesitancy. Researchers examined the associations of COVID-19 with longitudinal kidney function and proteinuria and compared these to similar associations with COVID-19 vaccination. In this cohort study of 2,055 patients with minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), membranous nephropathy, or ...

AMHERST, Mass. – States that enacted laws permitting children to carry and apply sunscreen at school experienced an increased interest in sun protection and a higher rate of sunscreen use among adolescents, according to new research by a University of Massachusetts Amherst resource economist.  Brandyn Churchill, assistant professor of resource economics at UMass Amherst, is co-author of the study that is the first to examine state-level “SUNucate” laws, which permit students to apply sunscreen at school and wear sun-protective clothing even if it does not ...

Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought. A research team led by the University ...
