After treatment for metastatic prostate cancer, a drop in prostate-specific antigen (PSA) levels in the blood is an indicator that the treatment is working. A recent real-world study published by Wiley online in CANCER indicates that reaching a PSA level below 0.2 ng/mL is an indicator of improved patient survival.
For children with early-onset progressive high myopia, the concern is not limited to stronger glasses or longer eyeballs. Over time, high myopia can be associated with structural changes at the back of the eye, including fundus tessellation, choroidal thinning, and myopic maculopathy. These changes may accumulate over many years and increase the risk of future visual impairment. This means that evaluating high myopia interventions should not rely only on refractive error and axial length, but should also consider whether the fundus is undergoing early structural deterioration. A study published in Eye Discovery provides new evidence from this perspective. Researchers from the Eye & ENT Hospital of Fudan University and the Key Laboratory of Myopia and Related Eye Diseases evaluated three-year changes in refractive status, axial length, and quantitative fundus parameters in children with progressive high myopia who underwent posterior scleral reinforcement (PSR). The procedure used a crosslinked bovine pericardial patch, with the aim of reinforcing the posterior part of the eye and exploring its potential effect on high myopia-related fundus changes.
Around one in six people experience infertility, with irregular or absent ovulation among the most common causes. The drug clomiphene citrate has long been a mainstay of fertility treatment, but a growing body of Adelaide University research is raising safety concerns about higher cumulative doses.
A real-world study from the Eye & ENT Hospital of Fudan University shows that, after implementation of a multifaceted surgical safety culture intervention, the rate of postoperative endophthalmitis after inpatient ophthalmic surgery continued to decline, offering a practical framework for surgical quality improvement.
New study finds that while common carp are highly vulnerable to a devastating virus, their close relatives help stop its spread, offering hope for fish farmers and freshwater ecosystems.
Researchers from Keio University have found that D-serine increases the growth of gastric cancer by creating an immunosuppressive and anti-inflammatory tumor microenvironment. Higher levels of D-serine in serum correlated with greater immune checkpoint inhibitor therapy resistance in tumors. Suppressing D-serine in circulation could improve the efficacy of immunotherapies against gastric cancer. These findings position D-serine within the broader field of cancer amino acid metabolism and point to it as a possible target for tumor evasion.
A research team led by Johnson Shayo at Kilimanjaro Christian Medical Center (KCMC) in Tanzania published research in Eye & ENT Research examining sensorineural hearing loss (SNHL) among hypertensive adults. The cross-sectional study of 201 hypertensive patients aged 18–60 years found a 23.9% prevalence of SNHL, predominantly bilateral (81.3%) and mild (70.8%) in severity. Six independent risk factors were identified: smoking (OR = 21.2), hypertension duration ≥ 5 years (OR = 16.0), female sex (OR = 9.4), age >50 years (OR = 6.4), alcohol consumption (OR = 5.5), and ototoxic drug use (OR = 4.5). These findings from East Africa highlight an often-overlooked aspect of hypertension management—hearing health.
Women live longer than men in nearly every country in the world, yet they experience higher rates of disability, dementia and many other age-related conditions. Scientists have long noted these differences, but they still do not fully understand why they occur — or how that knowledge can be used to improve healthy aging. A new $7.5 million, five-year grant from the National Institutes of Health will establish the USC Geroscience Specialized Center of Research Excellence on Sex Differences in Aging (GeroSCORE) to address that challenge.
