The “hygiene hypothesis” suggests that exposure to different types of microbes may protect against the development of diseases caused by allergens, but a new study in mice from Cornell University reveals that exposure to a variety of microbes and allergens in adults may actually worsen certain allergic symptoms. Professor of Immunology Avery August said: “Our data suggest that it is important to think about how we move around in the world and protect ourselves from exposure to microorganisms, because depending on our condition, if we move from a clean environment to a dirty environment, or from a dirty environment to…

A new report from the Geriatric Society of America (GSA) summarizes findings on the readiness of primary care providers to implement digital cognitive assessment (DCA) for use in the diagnostic process for cognitive impairment and dementia. Although the clinical literature consistently emphasizes early detection as a key tool in the management of Alzheimer’s disease and other dementias, subtle changes in cognition remain difficult to detect. Current reliance on analog, paper-based screening introduces a level of subjectivity and coarseness in the data, which can potentially miss subtle markers of early stage decline. ” Dr. Lisa C. McGuire, FAPA, FGSA,…

The herpes simplex virus partially liquefies the tightly packed gel-like interior of human cell nuclei to copy itself faster, a new study shows. The research focuses on how the nucleus of each human cell houses the genetic machinery used to copy instructions encoded in DNA as the cell divides and multiplies as part of growth. Viruses invade human cells and use their machinery to copy themselves, but their entry can be blocked by the dense structure of the nucleus. The new study, led by researchers at NYU Langone Health, found that the herpes simplex virus uses a protein called infectious…

Less than two weeks after Pfizer signed a deal with a Chinese pharmaceutical company to gain commercial rights to the GLP-1 drug, the country’s National Pharmaceutical Administration (NMPA) approved the treatment for patients with obesity. With the backing of Xianweiying’s shot, Pfizer has entered the weight-loss market and done so in the world’s largest country with a growing obesity problem. Last month, Pfizer signed a deal with Hangzhou-based Cywind Biosciences worth up to $495 million between upfront payments and potential milestone payments. The agreement gives Pfizer the rights to market the GLP-1 compound ecnoglutide in China. Ecnoglutide was also approved…

A systematic review of 19 studies examining abortion stigma in high-income countries found that abortion stigma exists at moderate levels. Prejudice against abortion was stronger among men, people with low incomes, political conservatives, and religious people. The paper is Sexual and reproductive health issues. Abortion stigma refers to the loss of public trust and negative labeling of individuals who seek, provide, or support abortion services. It operates through moral judgments that frame abortion as deviant, irresponsible, or sinful. Stigma may be expressed interpersonally through gossip, shame, exclusion, or hostility. It also operates through restrictive laws, institutional barriers, and policy debates.…

A new study has found that most countries are on the wrong track when it comes to meeting the United Nations’ 2030 global pesticide risk reduction targets, and are unlikely to be met without significant changes to agricultural systems around the world.To determine global pesticide risk, researchers used data on pesticide use in 65 countries from 2013 to 2019, as well as data on the toxicity of 625 pesticides associated with eight different species groups.Researchers found that only one country, Chile, is on track to meet the UN goal of reducing pesticide risks by 50% by 2030. The research…

Detailed three-dimensional reconstruction of the major sensory structures of ctenophores reveals much greater structural and functional complexity than scientists previously realized. The results suggest that some of the earliest animals may have had simple brain-like systems, providing new insights into how nervous systems evolved. Ctenophores (commonly known as comb jellies) are delicate gelatinous marine animals that appeared in Earth’s oceans about 550 million years ago. These organisms have specialized sensory structures called abdominal organs (AOs) that allow them to detect gravity, pressure, and light. New morphological research presented in scientific progress This indicates that this organ is significantly more complex…

A shy teenager who dreams of becoming a nurse, the teenager has spent the past four years working with her mother and other relatives on a small farm pulling weeds, planting berries and removing old plastic sheets from fields. In 2023, the teenager said he and other workers worked in the fields without pay for more than a month. Some adults complained to their supervisors. “He kept saying, ‘I’ll pay you next week, I’ll pay you next week,'” she said. On some days, there were no toilets on site and workers were not provided with water or shade, she said.…

Servier, run by a nonprofit group, continues to make money with its IDH-mutant glioma treatment Volanigo, and the drug company is moving deeper into rare oncology with a new M&A strategy. Servier on Friday announced a definitive agreement to acquire DayOne Biopharmaceuticals, a commercial-stage company developing targeted therapies for childhood cancer and other diseases, for $21.50 per share in cash. In a March 6 release, the companies announced that the total transaction value, which is expected to close in the second quarter, is approximately $2.5 billion. The highlight of the deal is undoubtedly Day One’s Ojemda (toborafenib). It is a…

New research reveals that attention-deficit/hyperactivity disorder actually consists of at least two distinct brain structural subtypes, each with unique physical characteristics and behavioral symptoms. These structural differences suggest that patients may ultimately benefit from highly individualized diagnostic and therapeutic strategies based on their unique biology. The study was published in the journal General psychiatry. Attention-deficit/hyperactivity disorder is a highly common neurodevelopmental disorder that affects children and adolescents around the world. Patients typically exhibit a variety of symptoms that fall into categories such as inattention, hyperactivity, and impulsivity. Because the symptoms vary from child to child, medical professionals classify the symptoms…
