Objectives: To investigate the relationship between corneal biomechanical changes and glaucoma severity in primary open angle glaucoma patients.
Design: Correlation study.
Materials And Methods: Our study included 70 glaucomatous eyes; they were divided in groups using Glaucoma Staging System Based on Humphrey Visual Field. Ocular Response Analyzer (ORA) was used in order to determine corneal hysteresis (CH) and corneal resistance factor (CRF); ultrasonic pachimetry (Ocuscan) to measure central corneal thickness (CCT) and Humphrey Visual Analyser to determine mean deviation (MD), pattern standard deviation (PSD) and visual field index (VFI). For statistical analysis we used descriptive analysis and linear regression using IBM SPSS Statistics Standard.
Outcomes: Out of the 70 eyes with primary open angle glaucoma examined that had visual acuity 0,7 or better, 35 were included in stage 1 (MD 0.01dB -> -6dB), 21 in stage 2 (MD -6.01dB -> -12dB) and 14 in stage 3 (MD -12.01dB -> -20dB). A considerable statistic correlation was found between CH and VFI both in the entire group of primary open angle glaucoma patients( r=0.44, p<0.001), and in stages 1 (r=0.44, p<0.009), 2 (r=0.51, p<0.01) and 3 (r=0.52, p<0.05).
Conclusion: The study shows a moderate correlation, statistically significant, between corneal hysteresis and visual field index in glaucoma patients. Ocular response analyzer can be considered an useful instrument in evaluation of primary open angle glaucoma patients.

Intra-Arterial Tenecteplase Following Endovascular Reperfusion for Large Vessel Occlusion Acute Ischemic Stroke: The POST-TNK Randomized Clinical Trial.
JAMA
January 2025
Department of Neurology, Xinqiao Hospital and The Second Affiliated Hospital, Army Medical University (Third Military Medical University), Chongqing, China.
Importance: The impact of adjunctive intra-arterial tenecteplase administration following near-complete to complete reperfusion by endovascular thrombectomy (EVT) for acute ischemic stroke is unknown.
Objective: To assess the efficacy and adverse events of adjunctive intra-arterial tenecteplase in patients with large vessel occlusion stroke who had achieved near-complete to complete reperfusion (defined as a score on the expanded Thrombolysis in Cerebral Infarction [eTICI] scale of 2c to 3) after EVT.
Design, Setting, And Participants: Investigator-initiated, randomized, open-label, blinded outcome assessment trial implemented at 34 hospitals in China among 540 patients with stroke due to proximal intracranial large vessel occlusion within 24 hours of the time they were last known to be well, with an eTICI score of 2c to 3 after EVT, and without prior intravenous thrombolysis.
Intra-Arterial Urokinase After Endovascular Reperfusion for Acute Ischemic Stroke: The POST-UK Randomized Clinical Trial.
JAMA
January 2025
Department of Neurology, Xinqiao Hospital and The Second Affiliated Hospital, Army Medical University (Third Military Medical University), Chongqing, China.
Importance: Persisting or new thrombi in the distal arteries and the microcirculation have been reported to limit the benefits of successful endovascular thrombectomy for patients with acute ischemic stroke. It remains uncertain whether intra-arterial thrombolysis by urokinase following near-complete to complete reperfusion by thrombectomy improves outcomes among patients with ischemic stroke due to large vessel occlusion.
Objective: To assess the efficacy and adverse events of intra-arterial urokinase after near-complete to complete reperfusion by thrombectomy for acute ischemic stroke due to large vessel occlusion.
Use of Maternal-Fetal Medicine Subspecialist Services by Commercially Insured Pregnant People.

Harvard School of Public Health, Boston, Massachusetts.
Importance: Improving access to high-quality maternity care and reducing maternal morbidity and mortality are major policy priorities in the US. Previous research has primarily focused on access to general obstetric care rather than access to high-risk pregnancy care provided by maternal-fetal medicine subspecialists (MFMs).
Objective: To measure access to MFM services and determine patient factors associated with MFM service use, including MFM telemedicine.

Importance: Compared with cisgender (CG) individuals, transgender and gender-diverse (TGD) individuals experience substantial social and economic disparities that can result in adverse mental health consequences. It is critical to understand potential barriers to care and to address the causes of the disparities in the future.
Objective: To characterize mental health care utilization among TGD veterans with depression.
