Research shows altered regulation of genes linked to prostate cancer among firefighters

Firefighters may have an increased risk of prostate cancer due to on-the-job chemical exposures, according to new research from the University of Arizona Mel and Enid Zuckerman College of Public Health and University of Michigan in collaboration with fire service partners and researchers around the country through the Fire Fighter Cancer Cohort Study. [...]

New PET agent provides same-day imaging for clear cell renal cell carcinoma patients

A novel investigational PET imaging agent can rapidly and accurately visualize lesions in clear cell renal cell cancer (ccRCC) patients according to new research published in the May issue of The Journal of Nuclear Medicine. [...]

Robotic total knee replacement improves outcomes but costs more, finds study

Total knee replacements performed with the help of a surgical robot have better outcomes on average than similar surgeries performed manually but can cost significantly more, a new study by UT Southwestern Medical Center researchers shows. The findings, published in Archives of Orthopaedic and Trauma Surgery, could help doctors and patients make more educated decisions on which option is best for each circumstance. [...]

Telehealth program created to improve access to specialty care found to reduce reliance on opioids in pain management

More Americans suffer from chronic pain than diabetes, heart disease, and cancer combined. Yet, a shortage of pain medicine specialists persists, causing many pain sufferers to seek care in primary care settings. [...]

How TP53 gene loss drives gastric cancer evolution

Gastric cancer (GC) ranks as the fifth-most common and fourth-deadliest cancer worldwide, presenting significant health challenges, particularly in China, where it is most prevalent and accounts for nearly half of newly diagnosed and death cases. In addition to somatic mutations, the complex pathology of GC is also determined by exposure to external factors like dietary and microorganisms such as Helicobacter pylori, Streptococcus anginosus, and Candida albicans.

Navigating the risks: Safeguarding maternal and fetal health in emergency agitation treatment

A recent review article provides critical insights into the management of acute agitation in reproductive-age females and during pregnancy within the emergency departments (EDs). The study emphasizes the importance of considering the safety of psychotropic medications in this demographic population, given the potential risks to both the patient and the fetus. [...]

The interaction of endorepellin and neurexin triggers neuroepithelial autophagy and maintains neural tube development

Neural tube defects (NTDs) rank as the second most prevalent congenital malformation in humans, impacting the central nervous system development in approximately 1 in every 1,000 live births. Over 300 genes, including the HSPG2 gene, are implicated in NTDs in mice. [...]

Biomarker found to help identify cells that can repair damaged blood vessels

Researchers have discovered a protein marker to help identify cells able to repopulate in patients with damaged blood vessels. Their findings, recently published in Circulation, could lead to new therapies for people with endothelial dysfunction, a type of disorder that contributes to coronary artery disease that may occlude with plaque and lack ability to carry sufficient blood into the heart tissue causing a heart attack.
