Estimate of Increase in Colorectal Cancer Diagnoses with Expansion of Fecal Immunochemical Testing in an Urban Safety-Net Population.

BACKGROUND: Fecal immunochemical test (FIT) is less effective in detecting advanced adenomas (AA) than colonoscopy. Increase in FIT for colorectal cancer (CRC) screening may lead to an increased number of undetected AAs which may develop into future CRCs. AIM: We determined the potential impact of FIT expansion on missed AAs and future CRC diagnoses in an urban, tertiary-care, safety-net hospital. METHODS: CRC and AA diagnoses were identified in patients undergoing colonoscopy for average-risk CRC screening or positive FIT between 2017 and 2019 at Boston Medical Center. Poisson regression modeling was used to estimate the frequency of AAs per year by age group using data from 2017 to 2019, assuming average outpatient volume and proportion of screening colonoscopies. Total number of patients who received FIT was extrapolated from those who underwent colonoscopy for positive FIT. We estimated AAs per year if 'one-time' FIT was used for screening in 75% and 100% of the population and subtracted this from the estimated AAs per year under the Poisson model to determine missed AAs. We used previously described, age and gender specific estimates of the annual progression of AA to CRC. RESULTS: The estimated number of CRCs detected per year is 4.6/1785 males and 4.6/2086 females screened. With 75% FIT expansion, we estimate an additional 3.5 (95% CI 1.3, 9.5) and 2.2 (95% CI 0.64, 7.6) CRCs; with 100% FIT expansion, we estimate an additional 7.4 (95% CI 3.7, 14.9) and 4.2 (95% CI 1.7, 10.5) CRCs, in 5 years, in males and females, respectively. CONCLUSION: Expansion of FIT may substantially increase CRC incidence.

Effects of GLP-1 and GIP on Islet Function in Glucose-Intolerant, Pancreatic-Insufficient Cystic Fibrosis.

Impaired insulin and incretin secretion underlie abnormal glucose tolerance (AGT) in pancreatic insufficient cystic fibrosis (PI-CF). Whether the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) can enhance pancreatic islet function in cystic fibrosis (CF) is not known. We studied 32 adults with PI-CF and AGT randomized to receive either GLP-1 (n = 16) or GIP (n = 16) during glucose-potentiated arginine (GPA) testing of islet function on two occasions, with either incretin or placebo infused, in a randomized, double-blind, cross-over fashion. Another four adults with PI-CF and normal glucose tolerance (NGT) and four matched control participants without CF underwent similar assessment with GIP. In PI-CF with AGT, GLP-1 substantially augmented second-phase insulin secretion but without effect on the acute insulin response to GPA or the proinsulin secretory ratio (PISR), while GIP infusion did not enhance second-phase or GPA-induced insulin secretion but increased the PISR. GIP also did not enhance second-phase insulin in PI-CF with NGT but did so markedly in control participants without CF controls. These data indicate that GLP-1, but not GIP, augments glucose-dependent insulin secretion in PI-CF, supporting the likelihood that GLP-1 agonists could have therapeutic benefit in this population. Understanding loss of GIP's insulinotropic action in PI-CF may lead to novel insights into diabetes pathogenesis.

Avoidance of primary healthcare among transgender and non-binary people in Canada during the COVID-19 pandemic.

Transgender (trans) and non-binary people experience barriers to culturally competent healthcare and many have reported avoiding care. COVID-19 and related mitigation strategies may have exacerbated avoidance, and poor mental health may be bidirectionally related to avoiding care. This study estimated the prevalence of primary care avoidance during the pandemic in a national sample of trans and non-binary people in Canada with a primary care provider and examined the association between poorer self-rated mental health and avoidance. In Fall 2019, Trans PULSE Canada collected multi-mode survey data from trans and non-binary people. In September to October 2020, 820 participants completed a COVID-19-focused survey. In this cross-sectional analysis, multivariable logistic regression models estimated odds ratios adjusted for confounders and weighted to the 2019 sample. The analysis included 689 individuals with a primary healthcare provider, of whom 61.2% (95% CI: 57.2, 65.2) reported fair or poor mental health and 25.7% (95% CI: 22.3, 29.2) reported care avoidance during the pandemic. The most common reason for avoidance was having a non-urgent health concern (72.7%, 95% CI: 65.9, 79.5). In adjusted analyses, those with fair or poor mental health had higher odds of avoiding primary care as compared to those with good to excellent mental health (adjusted odds ratio [AOR] = 2.37; 95% CI: 1.50, 3.77). This relationship was similar when excluding COVID-related reasons for avoidance (AOR = 2.52; 95% CI: 1.52, 4.17). Expansion of virtual communication may enhance primary care accessibility, and proactively assessing mental health symptoms may facilitate connections to gender-affirming mental health services.

Tongue Edema Secondary to Suspension Laryngoscopy.

OBJECTIVES: Suspension microlaryngoscopy (SML) is generally a safe, same-day procedure. Complications have been linked to prolonged operative time and substantial force applied to the tongue. This report of two cases describes marked tongue edema following SML, a complication not yet reported in the literature. METHODS: This is a retrospective review of two cases of severe tongue edema following SML. We reviewed the literature for similar reports and proposed treatment plans. RESULTS: Two patients, age 67 and 75, underwent SML for an interval of 247 minutes and 224 minutes for patient 1 and patient 2 respectively. Both developed severe tongue edema requiring inpatient monitoring and steroids. In both patients, the edema improved over several days and returned to baseline. There are no reported cases of this complication in the literature. CONCLUSION: Prolonged SML can lead to tongue edema requiring close airway monitoring. The edema was self-limited and resolved with steroids and close monitoring.

Diagnostic Value of Acoustic and Aerodynamic Measurements in Vocal Fold Movement Disorders and their Correlation with Laryngeal Electromyography and Voice Handicap Index.

OBJECTIVES: Investigate the relationships between the Voice Handicap Index, laryngeal electromyography, and objective acoustic voice testing in order to determine the utility of these measures in the management of vocal fold movement disorders. METHODS: A retrospective review of patients who had completed a Voice Handicap Index-10 (VHI-10) questionnaire, laryngeal electromyography (LEMG), and objective acoustic measurements (including jitter, relative average perturbation, shimmer, noise-to-harmonic ratio, and standard deviation of fundamental frequency). All three tests had been completed within 30 days of the initial evaluation. All patients' results for acoustic measures were recorded as standard deviations from the norm. LEMG results were converted to grade of paresis (mild, moderate, severe) based on the muscle with the lowest recruitment. Spearman correlation coefficients were calculated to determine the relationship between these three parameters. RESULTS: A total of 313 subjects were included in the analysis. VHI-10, LEMG (grade of paresis), and objective acoustic measures were, at best, weakly correlated. VHI-10 was better correlated than LEMG to each acoustic parameter including the average acoustic scores; however, the highest correlation observed only reached ρ = 0.349 (P < 0.001). The acoustic variables that correlated best with VHI-10 and LEMG were the standard deviation of the fundamental frequency (ρ = 0.349, P < 0.001) and shimmer (ρ = 0.207, P < 0.001), respectively. CONCLUSION: This study demonstrates that these measures are, at best, weakly associated. VHI-10 correlated better than LEMG (grade of paresis) to each acoustic voice analysis parameter. However, the maximum correlation coefficient observed was 0.349. Therefore, VHI-10 scores and objective voice acoustic measurements are not useful for predicting the severity of vocal fold movement disorders. Moreover, a given severity of paresis can have different effects on voice handicap and acoustic output in different individuals.

The Utility of Strap Muscle in Complex Type I Thyroplasties.

INTRODUCTION: Type I thyroplasty is a common procedure used to improve dysphonia secondary to glottic insufficiency caused by vocal fold paralysis, paresis, or bowing. Revision often involves more complex procedures that can be complicated by mucosal violation, hemorrhage, infection, and shifted or extruded implants. Intraoperative challenges can be managed successfully using autologous strap muscle rotation flaps. OBJECTIVES: Review vocal fold medialization with strap muscle as a viable option for thyroplasty, particularly operations with inadvertent mucosal disruption. METHODS: All operative records of the senior author's 30-year experience were queried for modified, complex, or revision type I thyroplasties. Each of these was reviewed, and only those utilizing autologous strap muscle rotation flaps for vocal fold medialization were included. Changes in voice quality were assessed using strobovideolaryngoscopic assessment of glottic closure and Voice Handicap Index-10 (VHI-10) scores when available. RESULTS: Seven patients were found to have undergone eight type I thyroplasty using autologous strap muscle flaps. Improved glottic closure was seen in all patients except one. This patient, complicated by a laryngeal fracture of unknown origin discovered at the time of surgery, had worse voice with strap muscle implantation intraoperatively; therefore, the patient's fracture was reduced, and medialization was postponed. All other patients reported improved voice quality both intra- and postoperatively. Pre- and postoperative VHI-10 scores were available for two of the seven cases with successfully implanted strap muscles. A decrease in VHI-10 was observed in both cases (mean = 11). No postoperative complications occurred in any patient. CONCLUSION: Although revision thyroplasties are relatively rare, they can be challenging. The seven cases presented herein illustrate the successful and safe use of autologous strap muscle rotation flaps for complex, revision type I thyroplasty procedures. They are particularly helpful in cases requiring additional soft tissue between the thyroid cartilage and mucosa in preparation for possible future medialization after Gore-Tex or Silastic implants, and for inadvertent mucosal disruption in which using a foreign implant might pose a risk of infection. Future studies should be performed with larger populations and longer follow-up to confirm the efficacy and safety of this procedure.

Stridor Related to Vagus Nerve Stimulator: A Case Report.

Implantation of a vagus nerve stimulator (VNS) can be an effective treatment for medically refractory seizures. Laryngeal side effects from a VNS can include hoarseness, cough, and shortness of breath. This report highlights a 5-year-old female who presented with stridor in the setting of acquired laryngomalacia, global developmental delay, and a VNS device. The case demonstrates that a VNS can exacerbate the symptoms of acquired laryngomalacia and that close monitoring of laryngeal side effects is crucial to optimizing care in this population.

Ludwig's angina and steroid use: A narrative review.

BACKGROUND: Ludwig's angina, a rapidly progressive cellulitis causing airway obstruction, has traditionally been managed with antibiotics and surgical intervention. More controversial is the use of steroids in the management of patients with this condition. This article summarizes the literature of steroid use in the management of Ludwig's angina. METHODS: The study used a narrative review method alongside the PRISMA guidelines for systematic reviews. PubMed, Ovid Medline, Cochrane, and Web of Science were searched for cases of Ludwig's angina with documented steroid use in patient management. Inclusion criteria were articles in the English language with direct patient outcomes. There were 17 articles selected with 31 patient cases. RESULTS: Most reports of steroid use in Ludwig's angina in the literature are case reports, with one retrospective review, and one letter to the editor. Dexamethasone was the steroid of choice in most cases reviewed. All patient cases reported used antibiotics alongside their steroid use, and 27 out of 31 patient cases required surgery. Most patients recovered with no further sequelae or complications. Three (9.68%) patients suffered mortality due to unrelated causes. CONCLUSIONS: Primary literature reporting the use of steroids in the management of Ludwig's angina includes few cases. While the role steroids have in these cases remains uncertain, the articles summarized do not suggest an adverse influence, and may suggest a benefit.
