Tumors do not only communicate with immune cells, blood vessels, and stromal tissue. Increasing evidence suggests that cancers may co-opt the nervous system and reshape the tumor microenvironment in ways that support proliferation, invasion, immune escape, and treatment resistance. A new review has been published the study The paper, by researchers from Zhejiang Provincial People’s Hospital and partner institutions, focuses on the interaction between peripheral nerves and cancer and proposes a three-dimensional framework for understanding this emerging field. The peripheral nervous system includes the sympathetic, parasympathetic, intestinal, and sensory pathways. Under normal physiological conditions, these nervous systems help regulate organ…
The fast, low-cost device detects tuberculosis from sputum and tongue swabs with high accuracy, raising hopes for easier diagnosis in areas where access to a laboratory remains a major barrier. Research: Pulmonary tuberculosis detection with MiniDock MTB using swab samples. Image credit: Media Lens King / Shutterstock.com In a recent prospective study published in New England Medical JournalHere, researchers discuss the accuracy and ease of use of the MiniDock MTB. This portable device accurately diagnoses pulmonary tuberculosis in diverse and demanding environments. The hidden burden of undiagnosed tuberculosis Tuberculosis (TB) remains the leading cause of infection-related death worldwide, killing more…
Although cardiovascular disease remains a major global health burden, many preclinical systems still struggle to predict how drug candidates will perform in the human heart. Although rodent models are limited by species differences, traditional two-dimensional cell cultures cannot fully reproduce the structure, mechanics, electrical activity, metabolism, and cellular communication of human heart tissue. In a review published in the studyIn , researchers from Shanghai University and collaborating institutions highlight how 3D cardiac constructs are emerging as a more clinically relevant platform for cardiovascular drug discovery and safety assessment. 3D cardiac constructs are typically generated from human pluripotent stem cells and…
Eating large amounts of ultra-processed foods (UPF) can significantly increase your risk of heart disease and death. european heart journal. This report combines the results of all currently available studies investigating the relationship between UPF and cardiovascular disease. Researchers say there is growing evidence that high intakes of UPF are associated with obesity, diabetes, hypertension, chronic kidney disease, and cardiovascular disease-related deaths. The authors urge physicians to discuss UPF intake with patients and provide practical advice to reduce consumption as part of daily medical care. This clinical consensus statement was prepared by the European Society of Cardiology’s Cardiology Practice Council…
A groundbreaking three-year trial in Sweden has shown that a gentler, slower approach to peanut immunotherapy can transform the lives of allergic infants, allowing most to safely tolerate the equivalent of 70 peanuts while dramatically reducing the risk of serious reactions that have long been a problem with conventional treatments. Study: Safety and efficacy of peanut oral immunotherapy in preschool children with slow escalation and low maintenance dosing: a randomized controlled trial. Image credit: triocean / Shutterstock In a recent study published in Lancet Community Health – EuropeA group of researchers evaluated the safety and efficacy of oral peanut immunotherapy,…
New psychological research suggests that an overwhelming desire to gain social value and a belief in the superiority of one’s group may lay the foundation for the formation of extreme personalities. This study highlights how these strong inner drives can lead individuals to sacrifice their own well-being for specific goals and values. These findings were recently published in the journal Frontiers in Social Psychology. Extremism is traditionally seen as strict adherence to an external political or religious ideology. In recent years, psychology has added a new perspective to the debate, proposing an underlying motivational mechanism called extreme personality. According to…
A short VR-based training program helped participants with autism practice interacting with police in realistic scenarios, reducing fidgeting and improving key response behaviors in just three sessions. Research: A virtual reality intervention to help autistic people interact with police: A randomized controlled clinical trial with teens and adults with autism. Image credit: Parilov / Shutterstock Recent randomized controlled trials (RCTs) Journal of Autism and Developmental Disabilities Virtual reality (VR)-based training may help people with autism navigate interactions with police more effectively than video-based education alone, the study suggests. Participants who used the Floreo Police Safety Module (PSM) demonstrated less fidgeting,…
A new study challenges the idea that a brief breathing meditation can quickly override automatic biases, finding that relaxation training can be effective in reducing split-second decision-making based on stereotypes. Study: The effects of mindful breathing meditation on stereotypic expression in two randomized, controlled, double-blind trials. Image credit: PeopleImages / Shutterstock.com In a recent study published in the journal pro swanresearchers at the University of Duisburg-Essen in Germany, evaluated whether short, mindful breathing meditations reduced the expression of social stereotypes. The cognitive science behind implicit bias In the brain, fixed mindsets allow individuals to process input from the environment quickly,…
Becoming parents at a young age tends to lead to worse long-term economic, educational, and physical health, which only begins to smooth out if you delay childbearing until your late 20s or early 30s. Recent research published in journals pro swan provide evidence that having children early in life disrupts standard life transitions and creates lasting disadvantages that continue for parents into adulthood. These findings suggest that public assistance programs aimed at young parents may be more effective if they target individuals up to age 30. Scientists Jordan McDonald and David Speed designed the study to investigate the specific age…
People who stay up later than planned may have weak physiological self-control. New research published in Journal of Health Psychology It is associated with decreased heart rate variability and increased bedtime procrastination. Many people experience the temptation to prolong their use of digital devices or complete additional tasks even when they know they should go to bed. This is a behavior known as bedtime procrastination. Scientists have long linked bedtime procrastination to difficulty managing behavior and emotions. It is thought that people who have a hard time prioritizing long-term well-being over short-term pleasure, or who have difficulty regulating negative emotions,…
