Objective: To evaluate the effect of para-aortic lymphadenectomy on blood pressure changes in endometrial cancer patients.
Materials And Methods: This retrospective study included patients with endometrial cancer treated surgically between 2017 and 2023. Patients undergoing para-aortic lymphadenectomy, up to the renal artery, in a non-nerve-sparing fashion, were compared with those undergoing pelvic lymphadenectomy or sentinel lymph node mapping. Data collected included age, body mass index, comorbidities including hypertension, diabetes mellitus, coronary artery disease, operative time, number of lymph nodes removed, tumor size, and postoperative complications. Preoperative blood pressure was recorded during outpatient visits, and postoperative measurements were collected daily during hospitalization and at follow-up visits. Statistical analyses assessed differences in systolic and diastolic blood pressure changes, operative outcomes, and complications.
Results: A total of 264 patients were analyzed. Patients in the para-aortic group had significantly longer operative times. Tumor size was larger in the paraaortic group than in another group. Systolic blood pressure decreased significantly in the para-aortic group compared to the control group (para-aortic: -17 mmHg vs. non-para-aortic: -1.10 mmHg, p<0.05), with a similar trend for diastolic pressure (-8.00 mmHg vs. -0.80 mmHg, p<0.05). Chylous ascites (15.6% vs. 5.6%) and ileus (0% vs. 12%) were more common in the para-aortic group, along with the administration of radiotherapy and chemotherapy. Both systolic and diastolic blood pressures were significantly lower in paraaortic group, in both early and late postoperative follow-up measures (p<0.005).
Conclusion: Aortic lymphadenectomy is associated with decreased blood pressure and may have therapeutic potential for hypertensive patients, highlighting the need for prospective randomized studies to explore this effect further.

Background: Previous studies indicated discrete lifestyle health metrics that benefit cardiovascular health are associated with better prognosis in inflammatory bowel disease (IBD), while evidence regarding the comprehensive impact of cardiovascular health remains limited. This study aimed to investigate the association between the overall cardiovascular health indicator, Life's Essential 8 (LE8), and the adverse outcomes of IBD.
Materials And Methods: We included 3,232 IBD participants recruited from the UK Biobank between 2006 and 2010.

Many patients experience long-term cognitive dysfunction after subarachnoid hemorrhage (SAH), and effective treatments are currently lacking. Carbon dioxide (CO2), an inexpensive and easily produced gas, forms carbonic acid when dissolved in water. Studies have suggested that hypercapnia may have neuroprotective effects.

Cordycepin, a natural adenosine derivative, exhibits multiple pharmacological effects on organisms. However, its distribution and metabolic characteristics have not been fully elucidated in vivo. In this study, ultra-high liquid chromatography tandem high-resolution mass spectrometry (UHPLC-HRMS/MS) was used to investigate the pharmacokinetic characteristics and effects of cordycepin on endogenous adenosine and inosine.
