Interhemispheric auditory connectivity requires normal access to sound in both ears during development

GordonAbstractDespite early bilateral cochlear implantation, children with congenital deafness do not develop accurate spatial hearing; we thus asked whether auditory brain networks are disrupted in these children. EEG responses were evoked unilaterally and bilaterally in 13 children with normal hearing and 16 children receiving bilateral cochlear implants simultaneously. Active cortical areas were estimated by the Time Restricted Artifact and Coherent source Suppression (TRACS) beamformer and connected cortical areas were identified by measuring coherence between source responses. A whole-brain analysis of theta band coherence revealed the strongest connections between the temporal areas in all conditions at early latencies. Stronger imaginary coherence in activity between the two auditory cortices to bilateral than unilateral input was found in children with normal hearing reflecting facilitation in the auditory network during bilateral hearing. The opposite effect, depressed coherence, was found during bilateral stimulation in children using cochlear implants. Children with cochlear implants also showed a unique auditory network in response to bilateral stimulation which was marked by increased connectivity between occipital and frontal areas. These findings suggest that corti...

AbstractBackgroundDeaf people experience health inequalities compared to hearing populations. The EQ-5D, a widely used, standardised, generic measure of health status, which is available in over 100 languages, was recently translated into British Sign Language (BSL) and initial validation conducted. Using data from this previous study of the EQ-5D-5L BSL we aimed to assess (1) whether responses to the EQ-5D differed between a sample of Deaf BSL users and the general population (2) whether socio-demographic characteristics and clinical measures were associated with EQ-5D index scores in Deaf BSL users and (3) the impact of ...

Autofluorescence revealed areas of hypoautofluorescence. Optical coherence tomography (OCT) showed depression of inner retinal surface, inner retinal hyporeflective spaces (pseudocysts), disorganization/thinning of outer retina, outer retinal tubulation, loss of external limiting membrane, ellipsoid and interdigitation zone, and thinning of the retinal pigment epithelium and choriocapillar...

CONCLUSIONS: There is moderate-certainty evidence that video feedback may improve sensitivity in parents of children who are at risk for poor attachment outcomes due to a range of difficulties. There is currently only little, very low-certainty evidence regarding the impact of video feedback on attachment security, compared with control: results differed based on the type of measure used, and follow-up was limited in duration. There is no evidence that video feedback has an impact on parental stress or anxiety (low- and very low-certainty evidence, respectively). Further evidence is needed regarding the longer-term impact ...

CONCLUSIONS: Findings from this national data set indicate that D/HH college students are more likely to consider or attempt suicide. These results underscore the need for focused suicide risk prevention interventions with this population. PMID: 31721275 [PubMed - as supplied by publisher]

By KIP SULLIVAN The notion that hospital readmission rates are a “quality” measure reached the status of conventional wisdom by the late 2000s. In their 2007 and 2008 reports to Congress, the Medicare Payment Advisory Commission (MedPAC) recommended that Congress authorize a program that would punish hospitals for “excess readmissions” of Medicare fee-for-service (FFS) enrollees. In 2010, Congress accepted MedPAC’s recommendation and, in Section 3025 of the Affordable Care Act (ACA) (p. 328), ordered the Centers for Medicare and Medicaid Services (CMS) to start the Hospital Readmissions Red...

The U.S. Food and Drug Administration has approved MED-EL USA’s cochlear implant system for single-sided deafness and asymmetric hearing loss. This is the first time cochlear implants have been green-lighted for these indications in the United States. MED-EL Cochlear Implant Systems, including SYNCHRONY and the recently FDA-approved SYNCHRONY 2, are now approved for people 5 years and older with single-sided deafness who have profound sensorineural hearing loss in one ear and normal hearing or mild sensorineural hearing loss in the other ear. They’re also approved for people 5 years and older with asymmetr...

AbstractThe national prevalence of depression and anxiety disorders among deaf adults who use American Sign Language (ASL) remains largely understudied. Data for self-reported depression and anxiety disorder diagnosis (n = 1,704 deaf adults;n = 3,287 hearing adults) as told by their healthcare providers were drawn from HINTS-ASL and HINTS datasets. Chi-square and Poisson regression analysis compared characteristics and predictors for depression or anxiety disorder diagnosis among deaf adults. Rate of diagnosed depression or anxiety disorder was significantly higher (25%) and occurred at earlier age (45 years; SD = 15) for ...

By Jan LundiusSTOCKHOLM / ROME, Jul 9 2019 (IPS) The Libyan catastrophe and the suffering of ”illegal” migrants are generally depicted as fairly recent events, though they are actually the results of a long history of greed, contempt for others and fatal shortsightedness. Like former Yugoslavia, Libya was created from a mosaic of tribal entities, subdued by colonial powers and then ruled by an iron-fisted dictator. Now, Libya is a quagmire where local and international stakeholders battle to control its natural resources. The country holds the largest oil reserves in Africa, oil and gas account for 60 percent o...
