Follow-up of children diagnosed with deafness in a neonatal hearing screening program in Manaus.

Objective: To evaluate the follow-up of children diagnosed with deafness in neonatal hearing screening and risk factors for hearing loss.

Methods: Quantitative, cross-sectional, and retrospective study to evaluate factors associated with hearing loss and the follow-up of cases of children diagnosed with audiological dysfunction, by analyzing electronic medical records of 5,305 children referred to a Specialized Center in Type I Rehabilitation, from January/2016 to February/2020, in the city of Manaus, Amazonas. The statistical study used Pearson's chi-square test and binary logistic regression in which odds ratio scans were obtained with reliability intervals of 95%.

Differential gene expression profile of multinodular goiter.

Introduction: The goiter, a neglected heterogeneous molecular disease, remains a major indication for thyroidectomies in its endemic regions.

Objectives: This study analyzed differential gene expression in surgical specimens diagnosed with multi nodular and compared the data to that of thyroid tissue without multinodular goiter from patients undergoing thyroidectomy in Manaus-AM, Brazil using RNA-seq technology.

Methodology: The transcriptome information of the surgical specimen fragments with and without multinodular goiter was accessed by Illumina HiSeq 2000 New Generation Sequencing (NGS) using the RNA-seq NEBNext® Ultra™ RNA Library Prep Kit for Illumina®-#E7530L protocol and differential gene expression analysis.
