Article Synopsis
  • - This study explores whether community-level social determinants of health (SDoH) impact the outcomes of acoustic neuroma more significantly than individual-level factors by analyzing data from over 23,000 patients diagnosed between 2010 and 2018.
  • - Researchers used statistical models to examine how community-level socioeconomic status (SES) and other factors influenced treatment delays, type of treatment received, and overall survival rates among these patients.
  • - Findings revealed that lower community-level SES was linked to higher all-cause mortality and less likelihood of receiving advanced treatments like stereotactic radiotherapy, emphasizing the negative role of community-level SDoH on patient care compared to individual factors.

Background: Children with cancer face a high risk of complications including prolonged mechanical ventilation requiring tracheostomies. While tracheostomies have been demonstrated to be a generally safe procedure, there remain significant rare complications and a paucity of literature addressing outcomes specifically for pediatric patients with cancer. The objective of this study was to characterize pediatric patients with cancer who underwent tracheostomies and describe their indications and outcomes for length of stay, decannulation, and complications.

  • This study examined how social determinants of health (SDoH) impact HPV-positive oropharyngeal squamous cell cancers (OPSCC) in different sexes, analyzing data from 2010 to 2018.
  • The researchers found that male patients, especially those who are Black or from lower socioeconomic backgrounds, experienced delays in treatment and worse mortality rates compared to females, especially Black females.
  • The study highlights significant disparities driven by social factors, emphasizing the need for tailored healthcare strategies and policies to address these issues in HPV-positive OPSCC patients.

Article Synopsis
  • The study aimed to investigate how social determinants of health (SDoH), specifically socioeconomic status using the Yost Index, affect disparities in care and outcomes for pediatric CNS tumors in the US.
  • Researchers conducted a retrospective analysis of data from over 18,000 patients aged 19 or younger with CNS tumors from 2010-2018, analyzing various demographic and treatment-related factors.
  • Results indicated significant disparities in mortality risks, treatment accessibility, delays, and cancer staging related to certain SDoH factors, suggesting that both individual and community-level influences play a critical role in health outcomes for these patients.

Article Synopsis
  • This study examines how various social determinants of health (SDH), not just socioeconomic factors, impact the management of head-neck melanomas (HNM) in the U.S. using the Social Vulnerability Index (SVI).
  • It analyzed data from over 374,000 adults diagnosed with HNM from 1975 to 2017, revealing that higher social vulnerability is linked to reduced surgical options, increased likelihood of radiation treatment, and more advanced disease at diagnosis.
  • Key findings indicate that household composition, socioeconomic status, and minority-language status significantly influence disparities in HNM management, despite limitations like unknown causes of death and reliance on county-level SVI calculations.

Introduction: Technology and internet access have become increasingly integrated into healthcare as the primary platform for health-related information and provider-patient communication. Disparities in access to digital resources exist in the United States and have been shown to impact health outcomes in various head and neck malignancies. Our objective is to evaluate the associations of digital inequity on health outcomes in patients with salivary gland cancer (SGC).

Article Synopsis
  • First branchial cleft anomalies are rare issues in the head and neck area that some kids are born with, and there's not much info on how to classify or treat them properly.
  • * Expert doctors worked together to come up with better ways to identify and manage these anomalies using a method called the Delphi method.
  • * They created a new classification system and treatment guidelines to help doctors give better care to kids with these conditions.

Background: Salivary gland cancers (SGC)-social determinants of health (SDoH) investigations are limited by narrow scopes of SGC-types and SDoH. This Social Vulnerability Index (SVI)-study hypothesized that socioeconomic status (SES) most contributed to SDoH-associated SGC-disparities.

Methods: Retrospective cohort of 24 775 SGCs assessed SES, minority-language status (ML), household composition (HH), housing-transportation (HT), and composite-SDoH measured by the SVI via regressions with surveillance and survival length, late-staging presentation, and treatment (surgery, radio-, chemotherapy) receipt.

As thyroid cancer incidence rises, it is increasingly valuable to recognize disparities in treatment and diagnosis. Prior investigations into social determinants of health (SDoH) are limited to pediatric populations or studies looking at single factors such as race or environmental influences. Utilizing the CDC-social vulnerability index and SEER-patient database to assess the amalgamated, real-world influence of varied SDoH and their quantifiable impact on thyroid cancer disparities across the United States.

Background: There is currently no comprehensive tool that quantifiably measures validated factors of modern technology access in the US for digital inequity impact on esophageal cancer care (EC).

Objective: To assess the influence of digital inequities on esophageal cancer disparities while accounting for traditional social determinants.

Methods: 15,656 EC patients from 2013-2017 in SEER were assessed for significant regression trends in long-term follow-up, survival, prognosis, and treatment with increasing overall digital inequity, as measured by the Digital Inequity Index (DII).

Objectives: To develop and implement a novel, comprehensive tool, the Digital Inequity Index (DII), that quantifiably measures modern-technology access in the US to assess the impact of digital inequity on laryngeal cancer (LC) care nationwide.

Methods: DII was calculated based on 17 census-tract level variables derived from the American Community Survey and Federal Communications Commission. Variables were categorized as infrastructure-access (i.

Purpose Of Review: Prior investigations in social determinants of health (SDoH) and their impact on pediatric head and neck cancers are limited by the narrow scope of cancer types and SDoH being studied while lacking inquiry on the interrelational contribution of varied SDoH in real-world contexts. The purpose of this review is to discuss the current research tackling these shortcomings of SDoH-based studies in head and neck cancer and to discuss means of applying these findings in prospective initiatives and implementations.

Recent Findings: Through leveraging contemporary, large-data analyses measuring diverse social vulnerabilities, several studies have identified comprehensive delineations of which social disparities contribute the largest quantifiable impact on the care of head and neck cancer patients.

Importance: Prior investigations in social determinants of health (SDoH) in pediatric head and neck cancer (HNC) have only considered a narrow scope of HNCs, SDoH, and geography while lacking inquiry into the interrelational association of SDoH with disparities in clinical pediatric HNC.

Objectives: To evaluate the association of SDoH with disparities in HNC among children and adolescents and to assess which specific aspects of SDoH are most associated with disparities in dynamic and regional sociodemographic contexts.

Design, Setting, And Participants: This retrospective cohort study included data about patients (aged ≤19 years) with pediatric HNC who were diagnosed from 1975 to 2017 from the Surveillance, Epidemiology, and End Results Program (SEER) database.

In this study, we report the isomerization of an aspartic acid residue in the complementarity-determining region (CDR) of crizanlizumab as a major degradation pathway. The succinimide intermediate and iso-aspartic acid degradation products were successfully isolated by ion exchange chromatography for characterization. The isomerization site was identified at a DG motif in the CDR by peptide mapping.

Pediatric head and neck tumors are uncommon but the consequences of radical resection are extensive. These tumors, benign and malignant, are uniquely challenging because of their proximity to critical functional and neurovascular structures and intimately affect speech, swallowing, voice, breathing, hearing, and vision. In addition, the psychosocial and emotional trauma from the cosmetic and functional consequences can be enduring.
