The polymyxin-B direct hemoperfusion OPTimal Initiation timing with Catecholamine PMX-OPTIC study: A multicenter retrospective observational study.

Background: Polymyxin-B direct hemoperfusion (PMX-DHP) is an endotoxin adsorption column-based blood purification therapy. Since one of the most potent effects of PMX-DHP is blood pressure elevations, it may be the most effective when it is introduced at the time when the need for vasopressors is the greatest, which, in turn, may reduce mortality.

Methods: A multicenter retrospective study was conducted at 24 ICUs in Japan.

The Hanging Strap Method: A Safe and Easy-to-Use Surgical Technique for Surgeons-in-Training Performing Difficult Laparoscopic Cholecystectomy.

Introduction Surgeons-in-training (SIT) perform laparoscopic cholecystectomy (LC); however, it is challenging to complete the procedure safely in difficult cases. We present a surgical technique during difficult LC, which we named the hanging strap method. Methods We retrospectively compared the perioperative outcomes between patients undergoing difficult LC with the hanging strap method (HANGS, n = 34), and patients undergoing difficult LC without the hanging strap method (non-HANGS, n = 56) from 2022 and 2024.

Role of Nitric Oxide Synthases in Respiratory Health and Disease: Insights from Triple Nitric Oxide Synthases Knockout Mice.

The system of nitric oxide synthases (NOSs) is comprised of three isoforms: nNOS, iNOS, and eNOS. The roles of NOSs in respiratory diseases in vivo have been studied by using inhibitors of NOSs and NOS-knockout mice. Their exact roles remain uncertain, however, because of the non-specificity of inhibitors of NOSs and compensatory up-regulation of other NOSs in NOS-KO mice.

Laparoscopic Splenectomy for Splenic Artery Aneurysms Associated With Infective Endocarditis: A Case Report.

Splenic artery aneurysms (SAAs) are a relatively uncommon but potentially life-threatening disease. In recent years, although there have been an increasing number of reports of interventional radiology (IVR) treatment for SAAs, there are still many cases in which surgical intervention is required. In particular, SAAs associated with infective endocarditis (SAAs-IE) are rare, and the treatment strategies and perspectives for SAAs-IE remain controversial.

Impact of Cognitive Impairment on Long-Term Outcomes After Transcatheter Aortic Valve Implantation.

Background: Cognitive impairment assessed using the Mini-Mental Status Examination (MMSE) is associated with short-term mortality after transcatheter aortic valve implantation (TAVI). We assessed the long-term prognostic impact of cognitive impairment in patients with severe aortic stenosis post-TAVI.

Methods And Results: We enrolled 1,057 consecutive patients who underwent TAVI at the Kokura Memorial Hospital and prospectively assessed them using the MMSE.

Impact of Preoperative Continued Aspirin Therapy on Perioperative Bleeding Complications in Patients Undergoing Gastrectomy for Malignancy.

Background The question of whether antiplatelet therapy (APT) should be discontinued prior to gastrectomy is controversial. In this study, we investigated the impact of continuing aspirin preoperatively on perioperative bleeding and thromboembolic complications in patients receiving gastrectomy for malignancy. Methods The study cohort comprised 1001 patients with malignant gastric tumors who had undergone gastrectomy between 2005 and 2021.

A Case of Hyperglycemia-Induced Epileptic Homonymous Hemianopsia.

Hyperglycemia sometimes initially presents with neurological manifestations, including seizures, visual hallucinations, choreoathetosis, hemiballismus, myoclonus, tremor, and consciousness disturbance. Epileptic seizures induced by hyperglycemia are reported to occur predominantly in the occipital lobe, and the epileptic form is mainly epilepsia partialis continua. Of the two patterns of hyperglycemia (ketotic or nonketotic), nonketotic hyperglycemia is more commonly associated with seizures because ketosis has an anticonvulsive effect, so hyperglycemia-induced seizures are generally seen in nonketotic patients.

Impact of Antiplatelet Therapy on 5-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization in Nonsignificant Obstructive Coronary Artery Disease.

Background: Because the clinical benefit of antiplatelet therapy (APT) for patients with nonsignificant coronary artery disease (CAD) remains poorly understood, we evaluated it in patients after fractional flow reserve (FFR)-guided deferral of revascularization.

Methods And Results: From the J-CONFIRM (Long-Term Outcomes of Japanese Patients with Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), we investigated 265 patients with deferred lesions who did not require APT for secondary prevention of cardiovascular disease. A 2-year landmark analysis assessed the relationship between APT at 2 years and 5-year major cardiac adverse events (MACE: composite of all-cause death, target vessel-related myocardial infarction, clinically driven target vessel revascularization).

Current Management and Therapy of Severe Aortic Stenosis and Future Perspective.

Intervention for severe aortic stenosis (AS) has dramatically progressed since the introduction of transcatheter aortic valve replacement (TAVR). Decades ago, controversies existed regarding comparing clinical outcomes between TAVR and surgical aortic valve replacement (SAVR) in various risk profiles. Recently, we discussed the durability of transcatheter heart valves and their lifetime management after aortic valve replacement (AVR).
