Introduction: Age-related hearing loss is an important risk factor for cognitive decline. However, audiogram thresholds are not good estimators of dementia risk in subjects with normal hearing or mild hearing loss. Here we propose to use distortion product otoacoustic emissions (DPOAEs) as an objective and sensitive tool to estimate the risk of cognitive decline in older adults with normal hearing or mild hearing loss.

Article Synopsis
  • The study examined how lipid peroxidation and antioxidant defenses vary over a 24-hour period in renal stone patients and healthy volunteers, focusing on their circadian rhythms.
  • Both groups were monitored under similar conditions, and blood samples were taken every six hours to measure levels of plasma lipid peroxides (MDA) and antioxidant enzyme activities (SOD, GPx, GR, CAT).
  • Results showed that renal stone patients had higher levels of MDA and lower levels of antioxidants compared to healthy subjects, indicating a significant circadian variation that may influence prevention and treatment strategies for kidney stones.

The circadian rhythm of uric acid concentration was studied under near-normal tropical conditions in 162 healthy volunteers (103 males and 59 females; 7 to 75 year). They were mostly medical students, staff members and members of their families. They were classified into 4 age groups: A (7-20 y; N = 42), B (21-40 y; N = 60), C (41-60 y; N = 35) and D (61-75 y; N = 25).

Many copper water lines for municipal drinking water in Santa Fe, New Mexico USA, have developed pinhole leaks. The pitting matches the description of Type I pitting of copper, which has historically been attributed to water chemistry and to contaminants on the copper tubing surface. However, more recent studies attribute copper pitting to microbial induced corrosion (MIC).
