The validity of using a self-report single question as a means to detect hearing loss in an adolescent population.

Objective: The overall objective in the study was to compare self-reported hearing based on a single question ("how good would you currently rate your hearing?") to measure hearing loss determined by audiometry in a cohort of adolescents. Prevalence of audiometrically measured hearing loss and frequencies of self-reported poor hearing as well as factors that have an impact on self-reported hearing were examined.

Design: Baseline and 5-year follow-up data of the Ohrkan study were used.

Prevalence of methicillin-sensitive, methicillin-resistant , and extended-spectrum beta-lactamase-producing in newborns: a cross-sectional study.

Background: The prevalence of antimicrobial-resistant bacteria and methicillin-sensitive (MSSA) in healthy newborns and the role of maternal transmission are scarcely discussed.

Objectives: The objective of this study was to evaluate the prevalence of MSSA, MRSA, and ESBL among healthy newborns. Additionally, mother-to-newborn transmission rates were investigated as well as antibiotic susceptibility of MSSA, MRSA, and ESBL isolates.
