AI Article Synopsis

  • The study reclassifies sudden deafness into three types: rise, decline, and consistent, and examines their relationships with hearing prognosis.
  • Analysis of 192 cases revealed that the length of the disease significantly affects hearing outcomes, especially within the first two weeks.
  • Findings suggest that the pathogenesis varies by type, with rise type linked to inner ear hydrops, decline type to hair cell damage, and consistent type to vascular stria damage, impacting overall prognosis.

Article Abstract

Reclassified the total deafness and flat type of sudden deafness,identified the relationship between new classification and hearing prognosis.To analyze 192 cases of patients with sudden deafness,especially for 159 cases of flat type and total deafness patients for further curve type classification,classified as rise,decline and consistent,analysis the possible factors with hearing in multiple factors using regression analysis.According to age group of 45 years old,>0.05,the difference has not statistically significant;Course of the disease according to the 0-7 days and 14 days more,<0.01,=4.291;8-14 days and 14 days,<0.05,=2.983;According to the flat type and total deafness grouping,<0.05,=0.409;According to the curve type of deafness,the difference between rise type and total deafness was significant,<0.01,=9.692;Decline type,consistent type compared to total deafness type,there is no statistically significant difference,>0.05.According to the pathogenesis of classification,sudden deafness can be divided into rise type,decline type and consistent type.The pathogenesis of rise type may be different degree of hydrops of inner ear.Decline type may be hair cell damage,and consistent type may be related to the damage of vascular stria and potential labyrinthitis,prognosis is poorer.

Language comprehension is an essential component of human development that is associated not only with expressive language development and knowledge acquisition, but also with social inclusion, mental health, and quality of life. For deaf and hard-of-hearing adults with intellectual disability, there is a paucity of measures of receptive sign language skills, although these are a prerequisite for individualized planning and evaluation of intervention. Assessments require materials and procedures that are accurate, feasible, and suitable for low levels of functioning.

Usher syndrome type 1C (USH1C) is a genetic disorder caused by mutations in the USH1C gene, which encodes harmonin, a key component of the mechanoelectrical transduction complex in auditory and vestibular hair cells. USH1C leads to deafness and vestibular dysfunction in humans. An Ush1c knockout (KO) mouse model displaying these characteristic deficits is generated in our laboratory.

Monitoring and assessing the level of lower limb motor skills using the Biodex System plays an important role in the training of football players and in post-traumatic rehabilitation. The aim of this study was to build and test an artificial intelligence-based model to assess the peak torque of the lower limb extensors and flexors. The model was based on real-world results in three groups: hearing ( = 19) and deaf football players ( = 28) and non-training deaf pupils ( = 46).

Background: Sudden sensorineural hearing loss (SSNHL) is associated with abnormal changes in the brain's central nervous system. Previous studies on the brain networks of SSNHL have primarily focused on functional connectivity within the brain. However, in addition to functional connectivity, structural connectivity also plays a crucial role in brain networks.
