ObjectiveTo assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD).MethodsProspective, multicenter cohort study of individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative. Patient demographics, comorbidities, radiographic imaging reports, laryngoscopy findings, patient‐reported outcome measures (PROM), and operative reporting were abstracted from a REDCap database and summarized using means, medians, percentages, frequencies. Paired t‐tests and Wilcoxon Signed Rank test were used to test pre‐ to post‐operative differences in RSI, EAT‐10, and VHI‐10 scores. Diagnostic test evaluation including sensitivity, specificity, positive, and negative predictive value with 95% confidence intervals were calculated comparing BAS findings to operative report.ResultsA total of 287 persons were enrolled; 13 (4%) patients were identified with confirmed KJD on operative reports. 100% underwent open transcervical excision. BAS has a 46.2% (95% confidence interval [CI]: 23.2, 70.9) sensitivity and 97.8% (95% CI: 95.3, 99.0) specificity in detecting a KJD and 50% (95% CI: 25.4, 74.6) positive predictive value but 97.4% (95%CI: 94.8, 98.7) negative predictive value. Preoperatively, patients reported mean (SD) RSI and EAT‐10 of 19.4 (9) and 8.3 (7.5) accordingly. Postoperatively, patients reported mean (SD) RSI and EAT‐10 as 5.4 (6.2) and 2.3 (3.3). Both changes in RSI and EAT‐10 were statistically significant (p = 0.008, p = 0.03).ConclusionKJD are rare and represent <5% of hypopharyngeal diverticula undergoing surgical intervention. Open transcervical surgery significantly improves symptoms of dysphagia. BAS has high specificity but low sensitivity in detecting KJD.Level of Evidence4 Laryngoscope, 133:2110–2115, 2023

At visit 3 (1993–1995) of the ARIC Study, 1.5T brain MRI was completed in 1,881 stroke-free participants (Mean age = 62.9±4.9, 50% Black). Cox regression examined associations between infarct group [infarct-free (referent; n = 1,611), smaller only (<3 mm; n = 50), larger only (≥3 mm but <20 mm; n = 185), both (n = 35)] and up to 25-year incident dementia (n = 539). Participants with both infarcts were over 2.5 times more likely to develop dementia [HR = 2.61; 95% CI = 1.44, 4.72]. Smaller only (HR = 1.22; 95% CI = 0.70, 2.13) and larger only (HR = 1.27; 95% CI = 0.92, 1.74) groups showed associations with wide confidence intervals, unsupported statistically. A late midlife infarct profile including smaller and larger infarcts may represent particular vulnerability to dementia risk.
