To determine whether Dermacentor reticulatus ticks are infected by Borrelia spp., Candidatus Neoehrlichia mikurensis, or Anaplasma phagocytophilum, we collected questing adults in the outskirts of Berlin, Germany, examined them for the presence of DNA of these pathogens, and compared the infection rates to those of sympatric Ixodes ricinus ticks. Questing D. reticulatus adults appeared not to harbor the bacterial pathogens that are prevalent in I. ricinus ticks. Based on our sample size, the estimated prevalence of each of these pathogens in D. reticulatus ticks would be well below three tenth of a percent (<0.3 %). For pathogens which so rarely infect D. reticulatus ticks, this tick likely plays no epidemiologic vector role for either their enzootic transmission cycle in nature or their transmission to people.

With the aging of the population, vision (VL), hearing (HL), and dual-sensory (DSL, concurrent VL and HL) loss will likely constitute important public health challenges. Walking speed is an indicator of functional status and is associated with mortality. Using the Health and Retirement Study, a nationally representative U.S. cohort, we analyzed the longitudinal relationship between sensory loss and walking speed. In multivariable mixed effects linear models, baseline walking speed was slower by 0.05 m/s (95% confidence interval [CI] = 0.04–0.07) for VL, 0.02 (95% CI = 0.003–0.03) for HL, and 0.07 (95% CI = 0.05–0.08) for DSL compared with those without sensory loss. Similar annual declines in walking speeds occurred in all groups. In time-to-event analyses, the risk of incident slow walking speed (walking speed < 0.6 m/s) was 43% (95% CI = 25–65%), 29% (95% CI = 13–48%), and 35% (95% CI = 13–61%) higher among those with VL, HL, and DSL respectively, relative to those without sensory loss. The risk of incident very slow walking speed (walking speed < 0.4 m/s) was significantly higher among those with HL and DSL relative to those without sensory loss, and significantly higher among those with DSL relative to those with VL or HL alone. Addressing sensory loss and teaching compensatory strategies may help mitigate the effect of sensory loss on walking speed.

Several studies have recently illuminated the relationship between hearing loss and hospitalizations, but little is understood as to why hearing loss is associated with greater risk for hospitalizations. This study examines the role of patient–provider communication as the mechanism by which those with hearing loss are more likely to be hospitalized, using the self-reported data from 12,654 Medicare beneficiaries from the 2016 Medicare Current Beneficiary Survey (MCBS) Cost and Use File. Multivariable logistic regression was used to model the odds of any hospitalization in the past year and negative binomial regression to model the incident rate ratio of hospitalization based on number of hospitalizations in the past year. It was found that Medicare beneficiaries who experience impaired communication with their physician due to trouble hearing have greater odds of hospitalization and a higher rate of all hospitalization over a 1-year period. Understanding the complex relationship between hearing loss, patient–provider communication, and hospitalizations may provide health care professionals with a better rational to address not only hearing loss but also impaired communication in the care of an individual.
