Hemorrhoids are a common and painful condition,with conventional treatments such as endoscopic rubber band ligation(ERBL)and injection sclerotherapy often falling short due to high recurrence rates and significant post-operative pain.A clinical trial by Qu et al introduces a novel approach called endoscopic polidocanol foam sclerobanding(EFSB).This multicenter randomized trial involved 195 patients with grade II and III internal hemorrhoids and demonstrated that EFSB significantly reduced recurrence rates and post-procedural pain while improving symptom relief and patient satisfaction compared to *** study's strengths include its robust design,comprehensive outcome evaluation,and patient-centered *** limitations such as the single-blind design and relatively short follow-up period,the findings suggest that EFSB could enhance clinical practice by offering a more effective and patient-friendly treatment *** research is needed to validate these results and explore the long-term benefits and cost-effectiveness of EFSB.

Obstacle removal in crowd evacuation is critical to safety and the evacuation system efficiency. Recently, manyresearchers proposed game theoreticmodels to avoid and remove obstacles for crowd evacuation. Game theoreticalmodels aim to study and analyze the strategic behaviors of individuals within a crowd and their interactionsduring the evacuation. Game theoretical models have some limitations in the context of crowd evacuation. Thesemodels consider a group of individuals as homogeneous objects with the same goals, involve complex mathematicalformulation, and cannot model real-world scenarios such as panic, environmental information, crowds that movedynamically, etc. The proposed work presents a game theoretic model integrating an agent-based model to removethe obstacles from exits. The proposed model considered the parameters named: (1) obstacle size, length, andwidth, (2) removal time, (3) evacuation time, (4) crowd density, (5) obstacle identification, and (6) route *** proposed work conducts various experiments considering different conditions, such as obstacle types, obstacleremoval, and several obstacles. Evaluation results show the proposed model’s effectiveness compared with existingliterature in reducing the overall evacuation time, cell selection, and obstacle removal. The study is potentially usefulfor public safety situations such as emergency evacuations during disasters and calamities.
