The impact of COVID-19 and vaccination status on outcomes in veterans with head and neck squamous cell carcinoma

BACKGROUND

The impact of both COVID-19 infection and vaccination status on patients with head and neck squamous cell carcinoma (HNSCC) remains unknown.

OBJECTIVE

To determine the impact of COVID-19 infection and vaccination status on 60-day mortality, cardiovascular, and respiratory complications in patients with a prior diagnosis of HNSCC.

METHODS

This was a retrospective cohort study through the Veterans Affairs (VA) Corporate Data Warehouse of Veterans with HNSCC who were tested for COVID-19 during any inpatient VA medical center admission. A cohort of patients was created of Veterans with a diagnosis of HNSCC of the oral cavity,oropharynx, hypopharynx, larynx, and nasopharynx based on International Classification of Disease (ICD) codes. Data collected included clinical/demographic data, vaccination status, and incidence of 60-day mortality, 60-day cardiovascular complication (including myocardial infarction, venous thromboembolism, cerebrovascular accident), and 60-day respiratory complication (including acute respiratory failure, acute respiratory distress syndrome, and pneumonia). The interactions between COVID-19 infection, vaccination status, morbidity and mortality were investigated.

RESULTS

Of the 14 262 patients with HNSCC who were tested for COVID-19 during inpatient admission, 4754 tested positive (33.3%), and 9508 (67.7%) tested negative. Patients who tested positive demonstrated increased 60-day mortality (4.7% vs. 2.0%, respectively; p < 0.001), acute respiratory failure (ARF; 15.4% vs. 7.1%, p < 0.001), acute respiratory distress syndrome (ARDS; 0.9% vs. 0.2%, p < 0.001), and pneumonia (PNA; 20.0% vs. 6.4%, p < 0.001) compared to those who never tested positive, respectively. Patients who received COVID-19 vaccination between 2 weeks and 6 months prior to a positive test demonstrated decreased rates of ARF (13.2% vs. 16.0%, p = 0.034) and PNA (16.7% vs. 20.9%, p = 0.003) compared to the unvaccinated group. A logistic regression of patients with COVID-19 infections who died within 60 days was performed, with no significant survival advantage among patients vaccinated between 2 weeks and 6 months prior to the positive test.

CONCLUSION

COVID-19 infection may significantly increase rates of 60-day mortality and respiratory complications in patients with HNSCC. COVID-19 vaccination between 2 weeks and 6 months prior to infection may decrease severity of respiratory complications but did not show significant mortality benefits in this study. These data highlight the need for surveillance of respiratory infection and vaccination in this vulnerable population.

Complications of eustachian tube balloon dilation: Manufacturer and User Facility Device Experience (MAUDE) database analysis and literature review

Objective

To provide an analysis of complications following eustachian tube balloon dilation as well as their treatments and outcomes.

Data Sources

PubMed, Ovid Embase, and MAUDE Database.

Review Methods

A systematic approach following PRISMA guidelines was used to identify publications pertaining to balloon dilation of the eustachian tube from PubMed and Ovid Embase databases was used. Once these publications were critically reviewed, the primary outcome extracted were reported complications. Additional complications were collected in the Manufacturer and User Facility Device Experience (MAUDE) database using the product class "eustachian tube dilation device" and searching through relevant manufacturers. Complications and outcomes were compared between these sources.

Results

Fifty five full-length manuscripts involving 7155 patients were included and 98 complications reported for a 1.4% complication rate. The most frequently reported adverse events were subcutaneous emphysema of the head and neck (19%), epistaxis (12%), and acute otitis media (11%). The MAUDE search returned 18 distinct patient entries, of which 12 (67%) reported complications. The most reported complications in the MAUDE database included subcutaneous emphysema (8, 67%) and pneumomediastinum (3, 25%). The most serious complication was a carotid artery dissection reported in one patient in the MAUDE database.

Conclusion

Eustachian tube dilation is rarely associated with complications, which nevertheless may lead to morbidity and medical emergencies. Patients and providers should recognize potential risks associated with this intervention as well as methods to manage complications.

Changes in United States Residency Program Online Presence Following COVID-19

PHENOMENON

The 2020-2021 residency application cycle was subject to major alterations following the COVID-19 global pandemic. This study determined the online presence of US-based residency training programs during this time period.

APPROACH

An official list of accredited US residency programs for 24 medical specialties was obtained through the Electronic Residency Application Service Programs' online presence and was evaluated for website ownership in addition to Twitter, Instagram, and Facebook account ownership. Date of social media account foundation and virtual opportunities offered were recorded. Doximity Residency Navigator for 2020-2021 was used to determine program rank, and programs were stratified by location using Association of American Medical Colleges regions. Program rank and geographic location were used to determine potential trends in online presence. This study was performed during the residency application cycle from September 2, 2020, to November 29, 2020, during which applications were submitted and the interview cycle began.

FINDINGS

Fifty-seven percent of the 4,562 programs had a presence on social media. One-third of all accounts were created after March 1, 2020, and most (58%) were residency program-associated. A total of 1,315 programs offered virtual open houses through Twitter (829), Instagram (792), and Facebook (295). First-quartile programs had significantly more social media accounts per program on average (1.8) than those in subsequent quartiles, and Western region programs had significantly more accounts per program on average (1.3) than the Central (1.0), Northeastern (1.0), and Southern (1.1) regions.

INSIGHTS

US residency programs created social media accounts and online opportunities for applicants following March 1, 2020. Online interactions may serve as substitutes at a time when in-person interaction is not possible. Future studies may examine the influence and impact of virtual interactions.Supplemental data for this article is available online at https://doi.org/10.1080/10401334.2022.2047050.

Quantifying and Reporting Outcomes in Pediatric Epilepsy Surgery: A Systematic Review

OBJECTIVE

Several instruments and outcomes measures have been reported in pediatric patients undergoing epilepsy surgery. The objective of this systematic review is to summarize, evaluate, and quantify outcome metrics for the surgical treatment of pediatric epilepsy that address seizure frequency, neuropsychological, and health-related quality of life (HRQL).

METHODS

We performed a systematic review according to PRISMA guidelines to identify publications between 2010 and June 2021 from PubMed, Embase, and the Cochrane Database of Systematic Reviews that report clinical outcomes in pediatric epilepsy surgery.

RESULTS

Eighty-one papers were included for review. Overall, rates of post-operative seizure frequency were the most common metric reported (n= 78 studies, 96%). Among the seizure frequency metrics, the Engel Epilepsy Surgery Outcome Scale (n= 48 studies, 59%) was most commonly reported. Neuropsychological outcomes, performed in 32 studies (40%) were assessed using 36 different named metrics. Health-Related Quality of Life (HRQL) outcomes were performed in 16 studies (20%) using 13 different metrics. Forty-six studies (57%) reported postoperative changes in anti-epileptic drug (AED) regimen and time-to-event analysis was performed in 15 (19%) studies. Only 13 outcomes metrics (1/5 seizure frequency, 6/13 HRQL, 6/36 neuropsychological) have been validated for use in pediatric patients with epilepsy and only 13 have been assessed through reliability studies (4/5 seizure frequency, 6/13 HRQL, and 3/36 neuropsychological). Of the 81 included studies, 17 (21%) used at least one validated metric.

SIGNIFICANCE

Outcome variable metrics in pediatric epilepsy surgery are highly variable. While nearly all studies report seizure frequency, there is considerable variation in reporting. HRQL and neuropsychological outcomes are less frequently and much more heterogeneously reported. Reliable and validated outcomes metrics should be used to increase standardization and accuracy of reporting outcomes in pediatric patients undergoing epilepsy surgery.
