ImportanceThe safety and effectiveness of combining surgical peripheral iridectomy (SPI) with goniosynechialysis (GSL) and goniotomy (GT) vs trabeculectomy for intraocular pressure (IOP) reduction remains unknown.ObjectiveTo investigate the safety and effectiveness at 1 year of SPI + GSL + GT vs trabeculectomy in advanced primary angle-closure glaucoma (PACG) without cataract.Design, Setting, and ParticipantsThis noninferiority randomized clinical trial was conducted at 8 tertiary eye centers in China. A total of 88 Chinese patients (88 eyes) with advanced PACG without cataract were enrolled from January 2022 to July 2023. Data were analyzed from August 2024 to September 2024. Mean (SD) patient age was 60.3 (7.3) years, and 52 patients (59.1%) were female. Forty-three patients were randomized to SPI + GSL + GT and 45 were randomized to trabeculectomy; 86 patients (97.7%) completed the 12-month follow-up.InterventionsParticipants were randomized 1:1 to receive SPI + GSL + GT or trabeculectomy.Main Outcomes and MeasuresThe primary outcome was IOP at 12 months (noninferior margin: 4 mm Hg). Secondary outcomes included surgical success (IOP: 5-18 mm Hg, ≥20% reduction from baseline, with or without antiglaucoma medications); postoperative complications and interventions, including bleb massage, suture lysis, or releasable sutures; and number of antiglaucomatous medications prescribed.ResultsAt 12 months, the SPI + GSL + GT group had a mean (SD) IOP of 15.6 (4.0) mm Hg vs 14.9 (4.2) mm Hg in the trabeculectomy group (difference, 0.5 mm Hg; 95% CI, −1.2 to 2.2; P = .55), which was within the 4-mm Hg noninferiority margin. Qualified success rates were 38 of 43 participants (88.4%) for SPI + GSL + GT and 42 of 45 participants (93.3%) for trabeculectomy (difference, −5.0%; 95% CI, −19.6% to 8.5%; P = .48). However, complete success rates were lower in the SPI + GSL + GT group (26 participants [60.5%]) vs the trabeculectomy group (37 participants [82.2%]; difference, −21.8%; 95% CI, −40.2% to −2.4%; P = .03). Postoperative complications were present for 8 participants (18.6%) in the SPI + GSL + GT group vs 9 participants (20.0%) in the trabeculectomy group (difference, −1.4%; 95% CI, −17.9% to 15.1%; P = .71). Postoperative interventions were lower in the SPI + GSL + GT group (3 participants [7.0%] vs 25 participants [55.6%]; difference, 48.6%; 95% CI, 32.2%-65.0%; P < .001). Median (IQR) numbers of medications used decreased from 2 (0-3) to 0 (0-1) in the SPI + GSL + GT group and from 2 (2-3) to 0 (0-0) in the trabeculectomy group (difference, −0.81; 95% CI, −1.36 to −0.26; P = .004).Conclusions and RelevanceIn this randomized clinical trial among patients with advanced PACG without cataract, SPI + GSL + GT demonstrated noninferiority (4-mm Hg margin) to trabeculectomy for IOP at 12 months, with fewer interventions (including bleb massage, suture lysis, or releasable sutures) but no difference in postoperative medication use. This suggests SPI + GSL + GT as a potential alternative to trabeculectomy for similar cases, pending validation in larger sample sizes with smaller noninferiority margins.Trial RegistrationClinicalTrials.gov Identifier: NCT05163951

ABSTRACT Background Although Percutaneous Coronary Intervention (PCI) is the cornerstone treatment acute myocardial infarction (AMI), its use in the elderly, specifically nonagenarians patients, is not well studied. This study sought to compare the outcomes and complications of nonagenarian patients who experienced AMI between those who underwent PCI and those who underwent medical treatment only. Methods We evaluated 301,440 nonagenarian (ages 90−99) patients who presented to the hospital with AMI who were listed in the National Inpatient Sample from 2016 to 2021. AMI was defined according to the ICD‐10 Diagnostic Codes. Multivariable logistic regression analysis was used to examine the association of PCI with primary outcomes of mortality and secondary outcomes. The temporal trend of both the incidence of PCI in nonagenarian patients as well as the mortality rate between 2016 and 2021 were expressed as percentages over time. Results Of the total ( n = 301,440) nonagenarian patients with AMI, 33,035 patients underwent PCI while 268,406 did not undergo PCI and rather, just utilized optimized medical therapy (OMT). Of these, 3290 (9.96%) died in the PCI group, and 43580 (16.24%) died in the OMT group. All of the secondary outcomes were significantly different between the PCI and OMT groups. Comparing the two groups, the PCI group was associated with decreased mortality (OR 0.63 [95% CI, 0.58−0.69]; p < 0.001), acute heart failure (OR 0.88 [95% CI, 0.82−0.95] p < 0.001), and AKI (OR 0.75 [95% CI, 0.70−0.79]; p < 0.001), and increased cardiogenic shock (OR 3.06 [95% CI, 2.77−3.38]. The temporal of PCI in nonagenarian patients showed an increase in frequency from about 8.3 in 2016 to about 13.7% in 2021. Furthermore, comparing the mortality between the PCI and OMT groups showed a significant difference with a decreased mortality in the PCI group. Conclusions Nonagenarian patients experiencing AMI who underwent PCI is associated with a significant mortality decrease compared to those who underwent OMT only. The PCI group was also associated with a significant decrease in multiple secondary complications including acute heart failure, AKI, acute stroke, and an increase in cardiogenic shock. Temporally, we have seen an increase in PCI being used in nonagenarian patients over the interval.

Myocardial Bridging (MB) is typically a benign congenital coronary anomaly. MB can infrequently result in complications such as myocardial ischemia, arrhythmias, and sudden cardiac death. Recent studies suggest an underlying genetic component for MB involving DES, FBN1, SCN2B, or NOTCH1. The role of percutaneous coronary intervention (PCI) in managing MB, compared to optimal medical therapy (OMT), remains uncertain. Our study used the National Inpatient Sample (NIS) Database to identify patients aged 18 or older with myocardial bridging who were managed with PCI versus medical therapy. We compared the outcomes between both groups including in-hospital mortality, the trend of management of MB and other in-hospital outcomes or complications. Our results showed no statistically significant difference between both subgroups when comparing in-hospital mortality and secondary outcomes of cardiac arrest and the development of an acute kidney injury (AKI). Patients with myocardial bridging treated with PCI had a higher risk of developing cardiogenic shock, requiring LVAD, and requiring the use of intra-aortic balloon pump (IABP) compared to the medical therapy subgroup. Our study suggests the decision to perform PCI in myocardial bridging patients should be individualized such as in patients with refractory symptoms despite medical therapy or those with known high-risk features.

ABSTRACTBackgroundMyeloproliferative neoplasms (MPN) are associated with an increased cardiovascular risk including acute coronary syndrome. However, there is a lack of comprehensive data regarding the rate of percutaneous coronary intervention (PCI), as well as the in‐hospital characteristics and outcomes for MPN patients.AimsWe aimed to evaluate the temporal trends and outcomes of PCI among patients with MPN.Methods and ResultsThe National Inpatient Sample database from 2016 to 2020 was queried to identify all PCI hospitalizations. Temporal trends and outcomes of patients with and without MPN following PCI were analyzed. Propensity score matching (PSM) was implemented to compare outcomes between MPN and non‐MPN groups. 2,237,210 PCI hospitalizations with 7560 (0.27%) patients with MPN were included in this study. Throughout the study period, the prevalence of MPN among PCI admissions remained stable (p‐value for trend = 0.12). Within the MPN subgroup, essential thrombocythemia (ET) was the predominant condition (53.2). Patients with MPN had higher prevalence of cardiovascular comorbidities than non‐MPN patients. Following PSM, MPNs were significantly associated with a higher risk of blood transfusions (OR: 1.66, 95% CI: 1.22−2.24, p = 0.001) and AKI (OR: 1.39, 95% CI: 1.17−1.65, p < 0.001). In contrast, the risk of in‐hospital mortality (OR: 1.18, 95% CI: 0.83−1.69, p = 0.354 and bleeding (OR: 1.43, 95% CI: 0.90−2.27, p = 0.127) did not significantly differ between the two groups.ConclusionsOur study demonstrated that while the prevalence of MPN among patients undergoing PCI remained stable, those with MPN faced higher risks of bleeding, blood transfusion and acute kidney injury. Further research is warranted to explore the underlying reasons for these increased risks and to improve outcomes in this high‐risk group.

AbstractThe intricate role of the autonomic nervous system (ANS) in regulating cardiac physiology has long been recognized. Aberrant function of the ANS is central to the pathophysiology of cardiovascular diseases. It stands to reason, therefore, that neuroscience‐based cardiovascular therapeutics hold great promise in the treatment of cardiovascular diseases in humans. A decade after the inaugural edition, this White Paper reviews the current state of understanding of human cardiac neuroanatomy, neurophysiology and pathophysiology in specific disease conditions, autonomic testing, risk stratification, and neuromodulatory strategies to mitigate the progression of cardiovascular diseases. image

The infrapatellar branch of the saphenous nerve (IPBSN) is implicated in nerve injury from different knee surgeries because of its intimate course relative to the knee joint capsule. Pain physicians encounter patients in their practice for the management of neuralgia of this nerve or in the context of advanced management of knee osteoarthritis. This article aims to provide a comprehensive review of the anatomy, sonoanatomy, and the intervention of the IPBSN in pain management of infrapatellar neuralgia and chronic knee pain.

Repeat expansions in the C9orf72 gene are the most common genetic cause of amyotrophic lateral sclerosis and familial frontotemporal dementia (ALS/FTD). To identify molecular defects that take place in the dorsolateral frontal cortex of patients with C9orf72 ALS/FTD, we compared healthy controls with C9orf72 ALS/FTD donor samples staged based on the levels of cortical phosphorylated TAR DNA binding protein (pTDP-43), a neuropathological hallmark of disease progression. We identified distinct molecular changes in different cell types that take place during FTD development. Loss of neurosurveillance microglia and activation of the complement cascade take place early, when pTDP-43 aggregates are absent or very low, and become more pronounced in late stages, suggesting an initial involvement of microglia in disease progression. Reduction of layer 2-3 cortical projection neurons with high expression of CUX2/LAMP5 also occurs early, and the reduction becomes more pronounced as pTDP-43 accumulates. Several unique features were observed only in samples with high levels of pTDP-43, including global alteration of chromatin accessibility in oligodendrocytes, microglia, and astrocytes; higher ratios of premature oligodendrocytes; increased levels of the noncoding RNA NEAT1 in astrocytes and neurons, and higher amount of phosphorylated ribosomal protein S6. Our findings reveal progressive functional changes in major cell types found in the prefrontal cortex of C9orf72 ALS/FTD patients that shed light on the mechanisms underlying the pathology of this disease.

Abstract Introduction The impact of multiple feeding arteries on clinical outcomes of cerebral arteriovenous malformations (AVMs) is not well understood. This study aims to compare outcomes between AVMs with multiple versus single feeding arteries. Patients and Methods Data from the Multicenter International Study for Treatment of Brain AVMs (MISTA) consortium were analyzed. Propensity score matching (PSM) was used to balance cohorts. Subgroup analysis was conducted for ruptured and unruptured AVMs and different treatment options, and multivariable logistic regression was applied to assess the impact of feeding artery origin. Results Among 953 patients, 661(69.4%) had multiple feeding arteries, and 292 (30.6%) had a single feeding artery. After PSM, which included 422 matched patients (211 in each group), the differences in obliteration rates (68.7% vs 74.8%, OR 0.73, 95% CI: 0.48–1.12, p = 0.16) and symptomatic complications (15.6% vs 11.8%, OR 1.37, 95% CI: 0.78–2.41, p = 0.25) were not significant. Subgroup analysis comparing ruptured and unruptured AVMs and different treatment options showed no significant differences across all subgroups. Multivariable analysis identified PICA feeders as significantly associated with increased odds of all complications (OR 7.33, 95% CI: 2.14–25.1, p = 0.002). Discussion and Conclusion AVMs with a single feeding artery were more likely to present with rupture, but no significant differences in obliteration rates or complications were observed between the groups after PSM. These findings suggest that while the number of feeding arteries may influence the initial presentation, it does not appear to impact overall treatment success or patient prognosis. Further prospective studies are needed to confirm these findings.
