    Kurzfassung: Hearing difficulty (HD) is one of the major health burdens in older adults. While aging-related changes in the peripheral auditory system play an important role, genetic variation associated with brain structure and function could also be involved in HD predisposition. We analyzed a large-scale HD genome-wide association study (GWAS; Ntotal = 501,825, 56% females) and GWAS data related to 3,935 brain imaging-derived phenotypes (IDPs) assessed in up to 33,224 individuals (52% females) using multiple magnetic resonance imaging modalities. To investigate HD pleiotropy with brain structure and function, we conducted genetic correlation, latent causal variable, Mendelian randomization, and multivariable generalized linear regression analyses. Additionally, we performed local genetic correlation and multi-trait colocalization analyses to identify genomic regions and loci implicated in the pleiotropic mechanisms shared between HD and brain IDPs. We observed a widespread genetic correlation of HD with 120 IDPs in females, 89 IDPs in males, and 171 IDPs in the sex-combined analysis. The latent causal variable analysis showed that some of these genetic correlations could be due to cause-effect relationships. For seven correlations, the causal effects were also confirmed by the Mendelian randomization approach: vessel volume→HD in the sex-combined analysis; hippocampus volume→HD, cerebellum grey matter volume→HD, primary visual cortex volume→HD, and HD→fluctuation amplitudes of node 46 in resting-state functional MRI dimensionality 100 in females; global mean thickness→HD and HD→mean orientation dispersion index in superior corona radiata in males. The local genetic correlation analysis identified 13 pleiotropic regions between HD and these seven IDPs. We also observed a colocalization signal for the rs13026575 variant between HD, primary visual cortex volume, and SPTBN1 transcriptomic regulation in females. Brain structure and function may have a role in the sex differences in HD predisposition via possible cause-effect relationships and shared regulatory mechanisms.

    Kurzfassung: We investigated the longitudinal association of herpes zoster (HZ), commonly known as “shingles,” and long‐term risk of stroke or coronary heart disease (CHD) among participants in 3 large US cohorts, the NHS (Nurses' Health Study), NHS II (Nurses' Health Study II), and HPFS (Health Professionals Follow‐Up Study). Methods and Results Participants were 79 658 women in the NHS (2000–2016), 93 932 women in the NHS II (2001–2017), and 31 440 men in the HPFS (2004–2016), without prior stroke or CHD. Information on HZ, stroke, and CHD was collected on biennial questionnaires and confirmed by medical record review. Cox proportional hazards regression models were used to estimate multivariable‐adjusted hazard ratios for stroke and for CHD according to years since HZ compared with never HZ. During 〉 2 million person‐years of follow‐up, 3603 incident stroke and 8620 incident CHD cases were documented. History of HZ was significantly and independently associated with higher long‐term risk of stroke and CHD. In pooled analyses, compared with individuals with no history of HZ, the multivariable‐adjusted hazard ratios (95% CIs) for stroke were 1.05 (0.88–1.25) among those with 1 to 4 years since HZ, 1.38 (1.10–1.74) for among those with 5 to 8 years since HZ, 1.28 (1.03–1.59) among those with for 9 to 12 years since HZ, and 1.19 (0.90–1.56) among those with ≥13 years since HZ. For CHD, the corresponding multivariable‐adjusted hazard ratios (95% CIs) were 1.13 (1.01–1.27) for 1 to 4 years, 1.16 (1.02–1.32) for 5 to 8 years, 1.25 (1.07–1.46) for 9 to 12 years, and 1.00 (0.83–1.21) for ≥13 years. Conclusions HZ is associated with higher long‐term risk of a major cardiovascular event. These findings suggest there are long‐term implications of HZ and underscore the importance of prevention.

    Kurzfassung: Epidemiologic and medical studies often rely on evaluators to obtain measurements of exposures or outcomes for study participants, and valid estimates of associations depends on the quality of data. Even though statistical methods have been proposed to adjust for measurement errors, they often rely on unverifiable assumptions and could lead to biased estimates if those assumptions are violated. Therefore, methods for detecting potential ‘outlier’ evaluators are needed to improve data quality during data collection stage. Methods In this paper, we propose a two-stage algorithm to detect ‘outlier’ evaluators whose evaluation results tend to be higher or lower than their counterparts. In the first stage, evaluators’ effects are obtained by fitting a regression model. In the second stage, hypothesis tests are performed to detect ‘outlier’ evaluators, where we consider both the power of each hypothesis test and the false discovery rate (FDR) among all tests. We conduct an extensive simulation study to evaluate the proposed method, and illustrate the method by detecting potential ‘outlier’ audiologists in the data collection stage for the Audiology Assessment Arm of the Conservation of Hearing Study, an epidemiologic study for examining risk factors of hearing loss in the Nurses’ Health Study II. Results Our simulation study shows that our method not only can detect true ‘outlier’ evaluators, but also is less likely to falsely reject true ‘normal’ evaluators. Conclusions Our two-stage ‘outlier’ detection algorithm is a flexible approach that can effectively detect ‘outlier’ evaluators, and thus data quality can be improved during data collection stage.

    Kurzfassung: In epidemiological hearing studies, estimating the association between exposures and hearing loss using audiometrically‐assessed hearing measurements is challenging due to the complex correlation structure in the clustered data, with clusters formed by the two ears of the same individual and the testing site and audiologist. We propose a linear mixed‐effects model to take into account the multilevel correlation structures of the data. Both theoretically and in simulation studies, we compare single‐ear linear regression models commonly used in published hearing loss studies with the proposed both‐ears linear mixed models properly accounting for the multi‐level correlations. Our findings include (1) when there are only participant‐level covariates, the worse‐ear linear regression models produce unbiased but typically less efficient estimators than the both‐ear and average‐ear approaches; (2) when there are ear‐level confounders, the worse‐ear method may lead to biased estimators and the average‐ear method produces unbiased but typically less efficient estimators than the both‐ear method; (3) the both‐ear method may gain efficiency when additionally adjusting for testing sites and audiologists. As an illustrative example, we applied the single‐ear and both‐ear methods to assess aspirin‐hearing association in the Nurses' Health Study II.
