Stenting Versus Medical Therapy for Symptomatic Intracranial Artery Stenosis: Long-Term Follow-Up of a Randomized Trial

Stroke, Ahead of Print. BACKGROUND:Whether the long-term benefit of stroke prevention when stenting is added to medical therapy (MT) over MT alone for symptomatic severe intracranial artery stenosis offsets the perioperative risks of the stenting has not been directly evaluated in a randomized trial. We aimed to compare the long-term ( >3 years) effect of stenting versus MT alone in patients with symptomatic severe intracranial artery stenosis in a randomized trial.METHODS:We extended the follow-up of 358 subjects enrolled in a multicenter, open-label, randomized trial conducted at 8 centers in China. Patients with transient ischemic attack or stroke attributed to severe intracranial stenosis (70% to 99%) were recruited between March 5, 2014, and November 10, 2016. The primary outcome was a composite of stroke or death within 30 days or stroke in the territory of the qualifying artery beyond 30 days. Other secondary outcomes included stroke in the territory of the qualifying artery, as well as disabling stroke or death after enrollment.RESULTS:A total of 358 patients (stenting 176 versus MT 182) were recruited from March 5, 2014, and followed up till January 22, 2024. The median duration of follow-up was 7.4 years (interquartile range, 6.0–8.0). The primary outcome was not significantly different (stenting 14.8% versus MT 14.3%; hazard ratio, 1.02 [95% CI, 0.58–1.77];P=0.97). No significant difference was found between groups for the secondary outcomes: stroke in the territory of qualifying artery (14.8% versus 14.3%; hazard ratio, 1.02 [95% CI, 0.58–1.77];P=0.97), disabling stroke or death (16.5% versus 14.3%; hazard ratio, 1.12 [95% CI, 0.66–1.91];P=0.70), and death (9.1% versus 7.1%; hazard ratio, 1.22 [95% CI, 0.58–2.58];P=0.60).CONCLUSIONS:This study provides compelling evidence that, even over prolonged observed periods, the addition of stenting to MT does not confer additional benefits to MT alone in patients with symptomatic severe intracranial artery stenosis. These results underscore the importance of MT as the cornerstone of long-term stroke prevention in this patient population.REGISTRATION:URL:https://www.clinicaltrials.gov; Unique identifier: NCT01763320.

Barriers to annual diabetic retinopathy screening and subsequent recommended follow-up adherence among Chinese diabetics: a cross-sectional and longitudinal study

Objectives
Adherence to routine annual eye evaluations for diabetes is frequently insufficient on a global scale. We evaluated the adherence to annual diabetic retinopathy screening (DRS) and recommended follow-up among Chinese patients with diabetes, and we also identified the associated risk variables.

Design
This was a cross-sectional and longitudinal study.

Setting
Patients with diabetes were inquired about their completion of DRS within the preceding year. All participants were required to complete the Compliance with Annual Diabetic Eye Exams Survey.

Participants
Participants with diabetes who initially sought eye examination from November 2021 to October 2023 at He Eye Specialist Hospital, Shenyang, China.

Outcome measures
Logistic regression analyses defined the risk factors associated with poor compliance with the annual DRS and recommended follow-up.

Results
There were 468 patients registered, with a mean age of 67.42±10.66 years. A total of 308 (65.8%) participants had DRS in the previous year. Rural residents (OR 1.704, 95% CI 1.019 to 2.850, p=0.042), vision-threatening diabetic retinopathy (VTDR) (OR 1.948, 95% CI 1.145 to 3.313, p=0.014), item 7 (over the past 4 weeks, I have felt blue, downhearted or depressed) (OR 0.624, 95% CI 0.401 to 0.971, p=0.037) and item 42 (I receive a reminder from my eye doctor’s office when it is time to schedule an exam) (OR 0.618, 95% CI 0.387 to 0.989, p=0.045) were associated with non-adherence to annual DRS. The compliance with DRS improved to 80.9% in the second year after health education and reminders of follow-up. VTDR (OR 3.063, 95% CI 1.852 to 5.066, p
