30-Second Takeaway

  • Oral AD109 modestly reduces AHI and improves oxygenation in PAP-intolerant OSA.
  • Rapid multiplex respiratory POCT did not lower overall same-day antibiotic prescribing.
  • Most tinnitus apps emphasize sound therapy; few implement guideline-recommended CBT components.

Week ending May 23, 2026

Five recent papers affecting ENT practice: oral pharmacotherapy for OSA, scrutiny of 'personalized' RCTs, rapid respiratory POCT, ED opioid-research decliners, and tinnitus apps

AD109 (aroxybutynin+atomoxetine) modestly lowers AHI and improves oxygenation versus placebo in PAP-intolerant OSA

AMERICAN JOURNAL OF RESPIRATORY AND CRITICAL CARE MEDICINEMay 18, 2026

In a 26-week randomized trial of 646 PAP-intolerant adults with mild-to-severe OSA, AD109 reduced AHI versus placebo by a mean of -4.0 events/hour (95% CI -6.4 to -1.6; P = .001). Model estimates showed a 44.1% versus 17.6% decrease from baseline in AHI favoring AD109 (P < .0001). AD109 also improved ODI and hypoxic burden but did not significantly improve PROMIS-Fatigue scores. Adverse-event–related discontinuation was substantially higher with AD109 (21.2% vs 3.1%), with common effects including dry mouth, nausea, insomnia, and urinary hesitation.

Trials labeled 'personalized/precision' are heterogeneous, often non-genomic, and frequently at high risk of bias

JOURNAL OF CLINICAL EPIDEMIOLOGYMay 18, 2026

This survey of 262 RCTs (2020–2022) found most trials used 'personalized' labels for behavioral, digital, or medication interventions rather than genomic approaches. Of 221 comparative trials, 156 (70.6%) reported favorable conclusions for personalized interventions, but transparency was poor. Most trials had high overall risk of bias (162/262, 68.6%) and data sharing was rare (13 trials, 5.0%). The term 'personalized' was applied inconsistently, limiting direct clinical applicability without scrutiny of methods.

Rapid respiratory multiplex POCT did not change same-day antibiotic prescribing in primary care

JAMA INTERNAL MEDICINEMay 18, 2026

In 552 primary-care patients with acute respiratory infections randomized to RM-POCT versus usual care, same-day antibiotic prescriptions occurred in 124 patients in each group (45%; OR 1.00, 95% CI 0.71–1.41). RM-POCT identified 19 viruses and 4 atypical bacteria in ~45 minutes and did not worsen patient-reported symptom severity. Prespecified subgroups showed reduced antibiotic prescribing when a virus was detected (OR 0.35, 95% CI 0.20–0.63). No prescribing reduction was seen in children <16 years, so clinical impact may be setting- and subgroup-dependent.

Edition context

Clinical signal

  • Monitor adverse effects and discontinuation when considering AD109; expect higher dropout with therapy.
  • Use RM-POCT selectively to target antibiotic reduction when a virus is detected, not routinely.
  • Interpret 'personalized' RCT claims cautiously given low transparency and high risk of bias.
