To analyze the performance of cochlear implants in French patients aged 65 and over, implanted between 2012 and 2016, using data from the French national registry for cochlear implants (EPIIC).

The French national registry incorporates patient data from before implantation and for three years after implantation, stratified in different age groups (18-39, 40-64years, 65-74years and>75years). Here, we assessed the latter two categories. Hearing was assessed using mono- and disyllabic words in a silent background. The Category of Auditory Performance (CAP) scale was also implemented and subjects took the Abbreviated Profile of Hearing Aid Benefit (Aphab) questionnaire.

The population aged over 65 accounted for 38% (n=1193) of the 3178 adult implanted patients. The performance for mono- and disyllabic words in silence, the CAP scores and the APHAB questionnaire answers for ease of communication, background noise and reverberation were dramatically improved at one year post-implantation (P<0.0001 for each score) and remained stable between one and three years thereafter. The percentage improvement was similar across all age groups. The scores for loud-noise intolerance did not change after cochlear implantation in any age group.

Cochlear implants improve hearing and communication in subjects aged 65 and over, with comparable efficiency to that achieved in younger subjects. Cochlear implantation should thus be proposed whenever hearing aids provide only limited benefit. However, between 2012 and 2016, cochlear implantation was given to less than 1% of the French population aged 65 and over with profound deafness.

Cells may have arisen from aqueous sequestration inside a lipid envelope studded with chromophores capable of capturing solar photons. Nitrogen incorporation in the primordial cell chemistry allowed synthesis of amino acids and nucleic acids, a prelude to RNA and subsequently DNA. Metagenomics provides access to nucleoprotein sediments synthesised by a googol of metabolically differentiated cells that have marked the evolution of life. Replication of a virus, a nucleoprotein particle, occurs passively in competent cells. Viruses are only identified in the context of the epidemic that they induce as a result of transmission from one host to another. By breaking down the viral particle, the host cell appears to resurrect the metabolic function of the nucleic acid, which synthesises its components without any form of control. Viral products undergo self-assembly and are exported by either exocytosis or cytolysis. In the absence of cells, viruses appear to be inert. However, intracellular contamination of a virus does not always result in replication the viral genome can disappear, remain latent, wake up, remain embedded in the cellular genome, become an oncogene or induce auto-immunity. The presence of endogenous retroviruses in eukaryotic cells raises the question of their possible role in evolution.

We analyzed multi-institutional data to determine if Step 3 performance tiers can identify radiology residents with increased risk of Core examination failure and submean performance.

We collected Step 3 scores (USMLE Step 3 or COMLEX Level 3) and American Board of Radiology (ABR) Core examination outcomes and scores for anonymized residents from 13 different Diagnostic Radiology residency programs taking the ABR Core examination between 2013 and 2019. Step 3 scores were converted to percentiles based on Z-score, with Core outcome and performance analyzed for Step 3 groups based on 50th percentile and based on quintiles. Core outcome was scored as fail when conditionally passed or failed. Core performance was measured by the percent of residents with scores below the mean. Differences between Step 3 groups for Core outcome and Core performance were statistically evaluated.

Data were available for 342 residents. The Core examination failure rate for 121 residents with Step 3 scores <50th percentile was 19.8% (fail relative risk = 2.26), significantly higher than the 2.7% failure rate for the 221 other residents. Of 42 residents with Step 3 scores in the lowest quintile, the Core failure rate increased to 31.0% (fail relative risk = 3.52). Core performance improved with higher Step 3 quintiles.

Step 3 licensing scores have value in predicting radiology resident performance on the ABR Core examination, enabling residency programs to target higher risk residents for early assessment and intervention.

Geneticin concentration Instagram facilitates easy content creation allowing for educators to utilize this resource for easy and rapid dissemination of educational content. The authors describe their experience of creating an online publicly available radiology teaching file on Instagram as a proof-of-concept, to help other individuals and institutions in leveraging social media to create and share quality educational content for current and future trainees.

Children with COVID-19 seem to have a relatively milder disease and better prognosis; however, severe disease or death could still occur in this age group. Although the knowledge on the clinical and epidemiology of COVID-19 in pediatric patients is being accumulated rapidly, relevant comprehensive review on its radiological manifestations is still lacking. The present article reviews the radiological characteristics of COVID-19 in pediatrics, based on the previous studies.

We conducted a systematic literature search for published articles by using Medline, Scopus, Google Scholar and Embase online databases. All studies describing CT findings of COVID-19 in pediatrics (<18years) were included.

A total of 39 studies with 850 pediatric patients were reviewed. 225 (26.5%) of patients had normal CT findings. Ground-glass opacities and consolidations were the most common CT abnormalities (384/625, 61.5%). Other findings were halo sign, interstitial opacities, bronchial wall thickening, and crazy-paving sign.
