Acute global longitudinal strain evaluation in patients with subacute to chronic chest pain: A pilot, observational study.

Background: Global longitudinal strain (GLS) imaging is a multifaceted modality that has been utilized in various fields of clinical cardiology in the recent past; however, its implementation for the assessment of ischemia has been limited. Objectives: This study aimed to document the functional changes in GLS secondary to acute myocardial ischemia in patients with chronic chest pain. Methods: In this unblinded, single-center, investigator-initiated, prospective pilot study, the functional changes in GLS at baseline, during, and immediately following coronary percutaneous intervention were monitored in 10 ambulatory patients who underwent elective catheterization. The exclusion criteria included a low ejection fraction, or a history of chemoradiation, myopathy, and congenital heart disease. Results: The average GLS at baseline, during the balloon intervention (BI), and 1-2 min after BI was -15.4 % ±â€¯3.3 %, -10.2 % ±â€¯3.6 %, and -16.1 % ±â€¯4.2 %, respectively. The average GLS decreased significantly by 5.1 % (95 % CI, -7.9 % to -2.3; P = 0.0013) from baseline to BI, increased by 6.3 % (95 % CI, 3.7 % to 8.9 %; P < 0.001) from BI to immediately post-BI, and increased by 0.7 % from baseline to post-BI (95 % CI, -0.4 % to 2.7 %; P = 0.161). Conclusion: Patients undergoing BI showed a significant decrease in the average GLS within 1-2 min of BI, with GLS returning to baseline subsequently, clearly demonstrating the efficacy of the modality and the clinical significance of data obtained. These functional changes replicate cardiac perfusion to the segments supplied by respective vessels and its effect with reperfusion or ballooning. The slight increase in GLS from baseline to post-intervention was not statistically significant, which could be attributed to the confounding factors. Analyzing our data, we can safely conclude that GLS is potentially a sensitive, temporal, and quantitative tool for identifying patients with acute ischemia with its limitations and need for further perfection of this modality. Therefore, GLS assessments on 2D echo can be used for risk stratification of patients with subacute to chronic chest pain concerning for ischemia in addition to EKG, troponins and other data obtained by non-invasive testing and evaluation.

Factors Associated With Otolaryngologists Performing Tracheotomy.

Importance: Tracheotomies are frequently performed by nonotolaryngology services. The factors that determine which specialty performs the procedure are not defined in the literature but may be influenced by tracheotomy approach (open vs percutaneous) and other clinicodemographic factors. Objective: To evaluate demographic and clinical characteristics associated with tracheotomies performed by otolaryngologists compared with other specialists and to differentiate those factors from factors associated with use of open vs percutaneous tracheotomy. Design, Setting, and Participants: This multicenter, retrospective cohort study included patients aged 18 years or older who underwent a tracheotomy for cardiopulmonary failure at 1 of 8 US academic institutions between January 1, 2013, and December 31, 2016. Data were analyzed from September 2022 to July 2023. Exposure: Tracheotomy. Main Outcomes and Measures: The primary outcome was factors associated with an otolaryngologist performing tracheotomy. The secondary outcome was factors associated with use of the open tracheotomy technique. Results: A total of 2929 patients (mean [SD] age, 57.2 [17.2] years; 1751 [59.8%] male) who received a tracheotomy for cardiopulmonary failure (652 [22.3%] performed by otolaryngologists and 2277 [77.7%] by another service) were analyzed. Although 1664 of all tracheotomies (56.8%) were performed by an open approach, only 602 open tracheotomies (36.2%) were performed by otolaryngologists. Most tracheotomies performed by otolaryngologists (602 of 652 [92.3%]) used the open technique. Multivariable regression analysis revealed that self-reported Black race (odds ratio [OR], 1.89; 95% CI, 1.52-2.35), history of neck surgery (OR, 2.71; 95% CI, 2.06-3.57), antiplatelet and/or anticoagulation therapy (OR, 1.74; 95% CI, 1.29-2.36), and morbid obesity (OR, 1.54; 95% CI, 1.24-1.92) were associated with greater odds of an otolaryngologist performing tracheotomy. In contrast, history of neck surgery (OR, 1.36; 95% CI, 0.96-1.92), antiplatelet and/or anticoagulation therapy (OR, 0.80; 95% CI, 0.56-1.14), and morbid obesity (OR, 0.94; 95% CI, 0.74-1.19) were not associated with undergoing open tracheotomy when performed by any service, and Black race (OR, 0.56; 95% CI, 0.44-0.71) was associated with lesser odds of an open approach being used. Age-adjusted Charlson Comorbidity Index score greater than 4 was associated with greater odds of both an otolaryngologist performing tracheotomy (OR, 1.26; 95% CI, 1.03-1.53) and use of the open tracheotomy technique (OR, 1.48, 95% CI, 1.21-1.82). Conclusions and Relevance: In this study, otolaryngologists were significantly more likely than other specialists to perform a tracheotomy for patients with history of neck surgery, morbid obesity, and ongoing anticoagulation therapy. These findings suggest that patients undergoing tracheotomy performed by an otolaryngologist are more likely to present with complex and challenging clinical characteristics.

Clinicodemographic Predictors of Tracheotomy Tube Size and Decannulation: A Multiinstitutional Retrospective Cohort Study on Tracheotomy.

OBJECTIVE: We aimed to discern clinico-demographic predictors of large (≥8) tracheostomy tube size placement, and, secondarily, to assess the effect of large tracheostomy tube size and other parameters on odds of decannulation before hospital discharge. SUMMARY OF BACKGROUND DATA: Factors determining choice of tracheostomy tube size are not well-characterized in the current literature, despite evidence linking large tracheostomy tube size with posttracheotomy tracheal stenosis. The effect of tracheostomy tube size on timing of decannulation is also unknown, an important consideration given reported associations between endotracheal tube size and probability of failed extubation. METHODS: We collected information pertaining to patients who underwent tracheotomy at 1 of 10 U.S. health care institutions between 2010 and 2019. Tracheostomy tube size was dichotomized (≥8 and <8). Multivariable logistic regression models were fit to identify predictors of (1) large tracheostomy tube size, and (2) decannulation before hospital discharge. RESULTS: The study included 5307 patients, including 2797 (52.7%) in the large tracheostomy cohort. Patient height (odds ratio [OR] = 1.060 per inch; 95% confidence interval [CI] 1.041-1.070) and obesity (1.37; 95% CI 1.1891.579) were associated with greater odds of large tracheostomy tube; otolaryngology performing the tracheotomy was associated with significantly lower odds of large tracheostomy tube (OR = 0.155; 95% CI 0.131-0.184). Large tracheostomy tube size (OR = 1.036; 95% CI 0.885-1.213) did not affect odds of decannulation. CONCLUSIONS: Obesity was linked with increased likelihood of large tracheostomy tube size, independent of patient height. Probability of decannulation before hospital discharge is influenced by multiple patient-centric factors, but not by size of tracheostomy tube.

AMSER Rad Path Case of the Month: Effect of Case-based Integration of Radiology and Pathology on Medical Student Education and Interdisciplinary Collaboration.

RATIONALE AND OBJECTIVES: Radiology and pathology are often underrepresented in undergraduate medical education. The Alliance of Medical Student Educators in Radiology (AMSER) hosts the AMSER Rad Path Case of the Month, an online archive of radiological case reports with pathology correlations submitted by medical students. The purpose of this study is to assess the value of preparing and submitting a case on medical students' educational experience. MATERIALS AND METHODS: Students who had cases accepted for publication in AMSER Rad Path Case of the Month from July 2018 to December 2019 were contacted by email to request their participation in a voluntary, anonymous 22-question survey. Surveys were sent to 35 students from seven institutions. RESULTS: Twenty three of the 35 students (65.7%) responded. Only five (21.7%) of respondents reported having previously followed a patient case through radiology and pathology during medical school, defined as interaction with a clinician in each specialty to discuss the case. When asked about their experience with AMSER Rad Path Case of the Month, most agreed or strongly agreed it was a valuable case-based learning experience (100%). Respondents also reported high satisfaction with improved understanding of disease process, increased understanding and ability to collaborate, and increased likelihood of participating in future academic work. CONCLUSION: AMSER Rad Path Case of the Month is a valuable case-based educational experience that deepens students' understanding of disease processes while affording them an opportunity for interdisciplinary and scholarly collaboration.

Factors That Influence Second-side Cochlear Implant Speech Recognition Outcomes.

OBJECTIVE: Assess relationships between patient, hearing, and cochlear implant (CI)-related factors and second-side CI speech recognition outcomes in adults who are bilaterally implanted. STUDY DESIGN: Retrospective review of a prospectively maintained CI database. SETTING: Tertiary academic center. PATIENTS: One hundred two adults receiving bilateral sequential or simultaneous CIs. OUTCOME MEASURES: Postimplantation consonant-nucleus-consonant (CNC) word and AzBio sentence scores at ≥12 months. RESULTS: Of patient, hearing and CI-specific, factors examined only postimplantation speech recognition scores of the first CI were independently associated with speech recognition performance of the second CI on multivariable regression analysis (CNC: ß = 0.471[0.298, 0.644]; AzBio: ß = 0.602[0.417, 0.769]). First-side postoperative CNC scores explained 24.3% of variation in second CI postoperative CNC scores, while change in first CI AzBio scores explained 40.3% of variation in second CI AzBio scores. Based on established 95% confidence intervals, 75.2% (CNC) and 65.9% (AzBio) of patients score equivalent or better with their second CI compared to first CI performance. Age at implantation, duration of hearing loss, receiving simultaneous versus sequential CIs, and preoperative residual hearing (measured by pure-tone average and aided speech recognition scores) were not associated with 12 month speech recognition scores at 12 months. CONCLUSIONS: The degree of improvement in speech recognition from first CI may predict speech recognition with a second CI. This provides preliminary evidence-based expectations for patients considering a second CI. Counseling should be guarded given the remaining unexplained variability in outcomes. Nonetheless, these data may assist decision making when considering a second CI versus continued use of a hearing aid for an unimplanted ear. LEVEL OF EVIDENCE: III.

Does Cognitive Dysfunction Correlate With Dizziness Severity in Meniére's Disease Patients.

OBJECTIVE: Characterize the relationship between cognitive dysfunction and the dizziness severity in Meniére's disease (MD) patients. STUDY DESIGN: Retrospective review. SETTING: University-based tertiary medical center. PATIENTS: Three hundred patients were evaluated for MD from 2015 to 2019. Excluding comorbid or alternative vestibular disorders, 29 patients with definite MD and available pre- and postintervention data were included for analysis. INTERVENTIONS: A progressive protocol of salt restriction, diuretics, steroid and/or gentamycin injection, and endolymphatic sac decompression for those refractory to medical therapy. MAIN OUTCOME MEASURES: Quality of life measured with the Dizziness Handicap Inventory (DHI) and cognitive function measured with the Cognitive Failures Questionnaire (CFQ). Pre- and posttreatment DHI and DHI subscale scores and change in these scores were correlated with pre- and posttreatment CFQ scores and change in CFQ with therapy. RESULTS: Analysis showed a number of limited associations between improvement in DHI and improvement in CFQ. Total DHI scores failed to correlate scores or variation in scores with change in CFQ (p = 0.091 and p = 0.085, respectively). Improvement in the CFQ false-triggering domain was significantly associated with improvement in the DHI physical subscale (r = 0.491, p = 0.007) and was nonsignificantly associated with improvement in total DHI and DHI emotional subscale scores (r = 0.422, p = 0.016 and r = 0.399, p = 0.032). CONCLUSIONS: The DHI correlates with several pre- and posttreatment measures of cognitive dysfunction (CFQ) in MD patients. However, change in DHI and CFQ with therapy correlate poorly. Overall, the commonly used DHI may fail to adequately assess cognitive dysfunction in MD patients possibly due to factors not directly implicated by measures of vestibular dysfunction, such as central nervous system or cognitive dysfunction; however, the specific physical and emotional subscales may offer helpful insight into cognitive dysfunction change/improvement with treatment.

A Meta-Analysis of the Association Between the Voice Handicap Index and Objective Voice Analysis.

Purpose Dysphonia can be evaluated by both patient-reported quality of life instruments and objective acoustic and aerodynamic analyses. However, less is known about the association between the two metrics. The goal of this study was to perform a meta-analysis of the correlation of the Voice Handicap Index (VHI-30) with the following objective parameters: fundamental frequency, jitter, shimmer, harmonics to noise ratio, noise to harmonic ratio, maximum phonation time, and the Dysphonia Severity Index. Method A literature search was performed in the PubMed, Scopus, and Cumulative Index of Nursing and Allied Health Literature databases. Inclusion criteria were subjects age 18 years and older with voice complaints and assessed by both VHI-30 and objective voice analysis. Results A literature search resulted in 1,297 unique articles, of which 310 underwent full-text review and 17 studies were included in quantitative analysis. Significant pooled correlation was observed for VHI-30 total with jitter (.301 [.177; .416]), shimmer (.255 [.162; .344]), noise to harmonic ratio (.200 [.111; .285]), maximum phonation time (-.227 [-.352; -.094]), and Dysphonia Severity Index (-.254[-.455; -.0286]). Significant correlations were observed in 4/7 objective parameters with the Physical subscale, 3/7 with the Functional subscale, and 2/7 with the Emotional subscale. All significant correlations were negligible (0-.3) or low (.3-.5). Conclusions Results from meta-analysis showed that correlations between objective voice parameters and the VHI-30 were negligible or low. Further study is needed to determine if correlations vary by patient demographics or specific pathology.

Emergent and urgent otologic surgeries during the SARS-CoV-2 pandemic: a protocol and review of literature.

OBJECTIVE: To review guidelines for otologic procedures during the SARS-CoV-2 pandemic and to present a protocol for emergent or urgent mastoidectomy at our institution. DATA SOURCES: Guidelines regarding emergent and urgent otologic procedures from otolaryngologic societies are reviewed. We described a protocol for emergent or urgent mastoidectomy at our institution. CONCLUSION: Patients requiring urgent or emergent mastoidectomy during the COVID-19 pandemic require prompt treatment. We make the following recommendations: Emergent or urgent otologic procedures should be performed in a contained environment, such as a tent created by the microscope drape. The surgical team should practice using instruments in the tent setup to prepare for real cases. Otologic procedures should adhere to guidelines set for high-risk procedures.

Association of Patient-Related Factors With Adult Cochlear Implant Speech Recognition Outcomes: A Meta-analysis.

Importance: Multiple studies have evaluated associations between post-cochlear implant (CI) speech recognition outcomes and patient-related factors. Current literature often appears equivocal or contradictory, so little is known about the factors that contribute to successful speech recognition outcomes with CIs. Objective: To use a meta-analysis to pool data from the extant literature and provide an objective summary of existing evidence on associations of patient-related factors and CI speech recognition outcomes. Data Sources: A literature search was performed using PubMed, Scopus, and CINAHL databases in January 2019 using the following search terms: cochlear implant or cochlear implants or cochlear implantation and speech recognition or word recognition or sentence recognition. Studies of postlingually deafened adult CI recipients that reported word or sentence recognition scores were included. Study Selection: Inclusion criteria were postlingual adult CI recipients 18 years or older with word or sentence recognition scores at minimum 6-month postimplantation. Studies that included patients undergoing revision or reimplantation surgery were excluded. Data Extraction and Synthesis: Following the Preferred Reporting Items for Systemic Reviews and Meta-analyses (PRISMA) guidelines, 1809 unique articles underwent review by abstract, and 121 articles underwent full-text review, resulting in 13 articles of 1095 patients for a meta-analysis of correlations. Random-effects model was used when the heterogeneity test yielded a low P value (P < .05). Main Outcomes and Measures: The planned primary outcome was the pooled correlation values between postimplant speech recognition scores and patient-related factors. Results: Of the 1095 patients included from the 13 studies, the mean age at implantation ranged from 51.2 to 63.7 years and the mean duration of hearing loss ranged from 9.5 to 31.8 years; for the 825 patients for whom sex was reported, 421 (51.0%) were women. A weak negative correlation was observed between age at implantation and postimplant sentence recognition in quiet (r = -0.31 [95% CI, -0.41 to -0.20]). Other correlations between patient-related factors and postimplant word or sentence recognition were statistically significant, but all correlations were absent to negligible (r = 0.02-0.27). Conclusions and Relevance: Given that most associations were weak, negligible, or absent, patient-related factors often thought to affect CI speech recognition ability offer limited assistance in clinical decision-making in cochlear implantation. Additional research is needed to identify patient-related and other factors that predict CI outcomes, including speech recognition and other important variables related to success with CIs.

Orbital complications of acute bacterial rhinosinusitis in the pediatric population: A systematic review and meta-analysis.

OBJECTIVES: Assess characteristics and outcomes of orbital complications of acute bacterial rhinosinusitis (ABRS) in the pediatric population and evaluate trends over time. METHODS: A literature search of pediatric orbital complications was performed in the following databases: Ovid MEDLINE, Scopus, and Cochrane Database of Systematic Reviews. Studies reporting data for at least 10 subjects with orbital complications of sinusitis under 18 years old were included. Studies were grouped by publication year; before 2010 and after and including 2010. Studies that only included patients with subperiosteal abscess (SPA) were grouped in a separate category. Data collected include demographics, Chandler class complications, intra-operative culture, treatment, and outcomes. Meta-analysis of proportion was performed to compare data from studies published before 2010 and data published in 2010 and after. RESULTS: Thirty-five studies met inclusion criteria. No significant difference was observed over time in gender of subjects in the all Chandler complications or SPA only groups (P > 0.72). The proportion of subjects presenting with Chandler IV complications decreased from 6.8% to 2.9% in recent studies (P = 0.019). The proportion of subjects treated surgically decreased from 45.2% to 21.7% in the all Chandler complications group (P < 0.0001) and from 90.0% to 47.9% in the SPA only group, P < 0.0001. The proportion of S. pneumoniae positive cultures decreased from 20.5% to 9.1% (P = 0.02). CONCLUSION: The demographics of pediatric patients treated for orbital complications of ABRS in published literature has been stable. Patients reported in more recently published studies are less likely to present with orbital abscess and more likely to receive conservative treatment. The proportion of positive Streptococcus pneumoniae cultures have decreased.
