Purpose Falls are considered a significant public health issue, and hearing loss has been shown to be an independent risk factor for falls. The primary objective of this study was to determine if hearing aid use modified (reduced) the association. We hypothesized that routine hearing aid use would reduce the impact of hearing loss on the odds of falling. If hearing aid users have reduced odds of falling, then that would have an important impact on falls prevention health care. Method Data from 8,091 individuals 40 years of age and older who completed National Health and Nutrition Examination Survey (NHANES) cycles 1999-2004 were used. NHANES comprises a series of cross-sectional studies, each of which is representative of the total civilian noninstitutionalized population of children and adults in the United States, enabling unbiased national estimates of health that can be independently reproduced. Self-reported hearing, hearing aid status, falls history, and comorbidities were extracted and analyzed using regression modeling. Results The 8,091 individuals were grouped based on a self-reported history of falls in the last year. Self-reported hearing loss was significantly associated with odds of falling. Categorizing individuals based on routine hearing aid use was included as an interaction term in the fully adjusted models and was not significant, suggesting no difference in falls based on hearing aid status. Conclusions The unique results of the current study show that when examining self-reported hearing in a nationally representative sample, hearing aid use does not appear to mitigate or modify the association between self-reported hearing and falls. Future research designs are highlighted to address limitations identified using NHANES data for this research and focus on the use of experimental designs to further understand the association between hearing loss and falls, including whether hearing loss may be a modifiable risk factor for falls.

A bacteriophage, designated FBB1, was isolated from spotted cucumber beetles (Diabrotica undecimpunctata) that were collected from a field where E. tracheiphila is endemic. FBB1 was classified into the Myoviridae family based on its morphology, which includes an elongated icosahedral head (106 × 82 nm) and a putatively contractile tail (120 nm). FBB1 infected all 62 E. tracheiphila strains examined and also three Pantoea spp. strains. FBB1 virions were stable at 55°C for 1 h and tolerated a pH range from 3 to 12. FBB1 has a genome of 175,994 bp with 316 predicted coding sequences and a GC content of 36.5%. The genome contains genes for a major bacterial outer-membrane protein, a putative exopolysaccharide depolymerase, and 22 predicted tRNAs. The morphology and genome indicate that FBB1 is a T4-like virus and thus in the Tevenvirinae subfamily. FBB1 is the first virulent phage of E. tracheiphila to be reported, and to date, is one of only two bacteriophages to be isolated from insect vectors of phytopathogens. Collectively, the results support FBB1 as a promising candidate for biocontrol of E. tracheiphila based on its virulent (lytic) rather than lysogenic lifestyle, its infection of all E. tracheiphila strains examined to date, and its infection of a few non-pathogenic bacteria that could be used to support phage populations when pathogen numbers are low.Net blotch diseases result in significant yield losses to barley industries worldwide. read more They occur as net-form and spot-form net blotch caused by P. teres f. teres (Ptt) and P. teres f. maculata (Ptm), respectively. Hybridisation between the forms was proposed to be rare, but recent identifications of field hybrids has renewed interest in the frequency and mechanisms underlying hybridisation. This study investigates the mating preference of Ptt, Ptm and laboratory-produced hybrids in vitro, using 24 different isolates and four different experimental setups. Two crosses in our study produced ascospores during two intervals separated by a 32-35 day period of no ascospore production. For these crosses Ptt isolates mated with isolates of the same form during the early ascospore production interval and produced hybrids during the later interval. Ptm isolates did not mate with isolates of the same form, instead hybridised with Ptt isolates. Analyses based on DArTseq™ markers confirmed that laboratory-produced hybrids, when given the choice to mate with both Ptt and Ptm, mated with Ptt isolates. These results unravel a novel concept that Ptt seems to have a greater reproduction robustness than Ptm, which could lead to increased prevalence of hybrid incidences in vivo.
