Adult mammals are generally believed to have limited ability to regenerate complex tissues and instead, repair wounds by forming scars. In humans and across mammalian species, the tympanic membrane (TM) rapidly repairs perforations without intervention. Using mouse models, we demonstrate that the TM repairs itself through a process that bears many hallmarks of epimorphic regeneration rather than typical wound healing.

Objectives: As the volume of research publications in the field of otolaryngology has increased, so has the need to qualify articles through bibliometric analyses to identify the most important and impactful work in the field. Herein, we aim to identify the 100 most disruptive articles in ENT over a 60-year period and examine how disruption index (DI) compares with other bibliometrics in identifying impactful works in the field.

Methods: In this cross-sectional bibliometric analysis, articles published between 1954 and 2014 in commonly referenced otolaryngology-head and neck surgery (OHNS) journals were queried in PubMed.

Due to commonalities in pathophysiology, age-related macular degeneration (AMD) represents a uniquely accessible model to investigate therapies for neurodegenerative diseases, leading us to examine whether pathways of disease progression are shared across neurodegenerative conditions. Here we use single-nucleus RNA sequencing to profile lesions from 11 postmortem human retinas with age-related macular degeneration and 6 control retinas with no history of retinal disease. We create a machine-learning pipeline based on recent advances in data geometry and topology and identify activated glial populations enriched in the early phase of disease.

Bioabsorbable implants (eg, Latera) have recently been approved for addressing nasal valve collapse. The purpose of this study is to summarize adverse events and treatment sequelae associated with bioabsorbable nasal implants queried in the Manufacturer and User Facility Device Experience (MAUDE) database. Of the 26 device reports entered between March 2017 and April 2022, the most frequently reported complications included abscess (n = 13) and implant protrusion (n = 5).

Nearly half of all olfactory dysfunction (OD) clinical trials since 2010 are COVID-19-related. COVID-19-related OD trials are published significantly faster than COVID-19-unrelated trials. High-quality clinical trials and publications are crucial to discovering effective treatments.

Using publicly available Medicare data, we performed a retrospective cross-sectional analysis of separation between otolaryngologists and affiliated medical groups between 2014 and 2021. During this period, the cumulative turnover rate among otolaryngologists was 36.4%, with annual turnover rates ranging between 6.

Purpose: Acute primary angle closure (APAC) is an ophthalmologic emergency. Nationwide data on the epidemiology and clinical characteristics of APAC are lacking despite the associated visual morbidity.

Patients And Methods: A retrospective cross-sectional study using the Nationwide Emergency Department Sample (NEDS).

Background: We studied whether comorbid conditions affect strength and duration of immune responses after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) messenger RNA vaccination in a US-based, adult population.

Methods: Sera (before and after BNT162b2 vaccination) were tested serially up to 12 months after 2 doses of vaccine for SARS-CoV-2-anti-Spike neutralizing capacity by pseudotyping assay in 124 individuals; neutralizing titers were correlated to clinical variables with multivariate regression. Postbooster (third dose) effect was measured at 1 and 3 months in 72 and 88 subjects, respectively.

Background & Aims: Low-risk branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) lacking worrisome features (WF) and high-risk stigmata (HRS) warrant surveillance. However, their optimal duration, especially among cysts with initial 5 years of size stability, warrants further investigation. We systematically reviewed the surveillance of low-risk BD-IPMNs and investigated the incidence of WF/HRS and advanced neoplasia, high-grade dysplasia, and pancreatic cancer during the initial (<5 years) and extended surveillance period (>5-years).

Background: We studied whether comorbid conditions impact strength and duration of immune responses after SARS-CoV-2 mRNA vaccination in a US-based, adult population.

Methods: Sera (pre-and-post-BNT162b2 vaccination) were tested serially up to 12 months after two doses of vaccine for SARS-CoV-2-anti-Spike neutralizing capacity by pseudotyping assay in 124 individuals; neutralizing titers were correlated to clinical variables with multivariate regression. Post-booster (third dose) effect was measured at 1 and 3 months in 72 and 88 subjects respectively.

Study Design: Cross-sectional analysis of completed and terminated spine-related clinical trials in the ClinicalTrials.gov registry.

Objective: The aim was to quantify completed and terminated spine-related clinical trials, assess reasons for termination, and determine predictors of termination by comparing characteristics of completed and terminated trials.

Allogeneic hematopoietic cell transplant (allo-HCT) remains the only potentially curative therapeutic modality for patients with primary or secondary myelofibrosis (MF). However, many patients are considered ineligible for allo-HCT, and transplant-related mortality can be substantial. Data on the efficacy and safety of allo-HCT are mixed and largely derived from retrospective studies.

Here, we present a protocol to analyze genetic variants derived from the whole-exome sequencing (WES) of proband-parent trios. We provide stepwise instructions for using existing pipelines to call mutations (DNMs) and determine whether the observed number of such mutations is enriched relative to the expected number. This protocol may be extended to any human disease trio-based cohort.

Background: This study sought to assess microsatellite and KRAS status, prevalence, and impact on outcome in stage IV colorectal cancer (CRC).

Materials And Methods: The 2010 to 2016 US National Cancer Database was queried for adult patients with stage IV CRC. Prevalence of microsatellite status (microsatellite instability-high [MSI-H] or microsatellite stable [MSS]) and KRAS status (KRAS mutation or wild-type) of the primary CRC was assessed.

Article Synopsis
  • * A study analyzed the genomes of 290 TN patients and found an increase in harmful genetic variants linked to GABA receptor-binding genes, suggesting a disruption in pain signaling.
  • * Additional findings also pointed to rare mutations in sodium and calcium channels, indicating that issues with ion transport might contribute to TN symptoms.

Background: We and others have identified mutually exclusive molecular subgroups of meningiomas; however, the implications of this classification for clinical prognostication remain unclear. Integrated genomic and epigenomic analyses implicate unique oncogenic processes associated with each subgroup, suggesting the potential for divergent clinical courses. The aim of this study was to understand the associated clinical outcomes of each subgroup, as this could optimize treatment for patients.

In addition to commonly associated environmental factors, genomic factors may cause cerebral palsy. We performed whole-exome sequencing of 250 parent-offspring trios, and observed enrichment of damaging de novo mutations in cerebral palsy cases. Eight genes had multiple damaging de novo mutations; of these, two (TUBA1A and CTNNB1) met genome-wide significance.

Psychiatric well-being impacts on general satisfaction and quality of life. This study explored how the presence of psychiatric diagnoses affects patient-reported outcomes in breast reconstruction and on selection of reconstructive modality. Patients who received breast reconstruction at a tertiary hospital between 2013 and 2018 and completed the BREAST-Q survey were included.

Objective: Recent large-cohort sequencing studies have investigated the genomic landscape of meningiomas, identifying somatic coding alterations in NF2, SMARCB1, SMARCE1, TRAF7, KLF4, POLR2A, BAP1, and members of the PI3K and Hedgehog signaling pathways. Initial associations between clinical features and genomic subgroups have been described, including location, grade, and histology. However, further investigation using an expanded collection of samples is needed to confirm previous findings, as well as elucidate relationships not evident in smaller discovery cohorts.

Timely dissemination of results from clinical studies is crucial for the advancement of knowledge and clinical decision making. A large body of research has shown that up to half of clinical trials do not publish their findings. In this study, we sought to determine whether clinical trial publication rates within neurology have increased over time.
