Article Abstract
Rare event probabilities play an important role in the understanding of the behavior of biochemical systems. Due to the intractability of the most natural Markov jump process representation of a system of interest, rare event probabilities are typically estimated using importance sampling. While the resulting algorithm is reasonably well developed, the problem of choosing a suitable importance density is far from straightforward. We therefore leverage recent developments on simulation of conditioned jump processes to propose an importance density that is simple to implement and requires no tuning. Our results demonstrate superior performance over some existing approaches.

Eur J Case Rep Intern Med
July 2025
Intensive care unit, Clinical Hospital Sveti Duh, Zagreb, Croatia.
Background: Tacrolimus is a commonly used immunosuppressant with well-defined side effects, including hypertriglyceridemia and hyperglycaemia. However, acute pancreatitis is still not widely recognized as an adverse event related to tacrolimus.
Case Presentation: A 60-year-old male was admitted to the intensive care unit with symptoms and signs of acute pancreatitis.
Background: Acupuncture is a widely recognized complementary therapy with proven therapeutic benefits; however, concerns regarding patient safety persist due to adverse events ranging from minor complications to severe outcomes like pneumothorax and nerve injury.
Objective: This study aims to identify common adverse events in acupuncture, propose innovative risk mitigation strategies, establish standardized best practices, enhance practitioner training, and examine global disparities in safety protocols.
Design: Comprehensive review of existing literature, clinical case studies, and international safety guidelines.
Stroke risk following bee and wasp stings: a systematic review of ischemic and hemorrhagic events.

August 2025
One Health Research Group, Faculty of Health Science, Universidad de Las Americas, Quito, Ecuador.
Background: Each year, approximately 100 million cases of bee and wasp stings are re-ported globally, with the majority resulting in mild reactions. However, in rarer instances, these stings can lead to severe and potentially fatal outcomes, including ischemic or hemorrhagic cerebral events. This article aims to synthesize and analyze the current evidence on the association between bee and wasp stings and the occurrence of ischemic and hemorrhagic strokes.

Here, we report the case of a 74-year-old man who developed diarrhea, abdominal pain, and oral intake difficulty and was subsequently hospitalized after receiving atezolizumab for pulmonary adenocarcinoma. Computed tomography and enterocolonoscopy revealed active inflammation in the small intestine but not in the colon, leading to the final diagnosis of irAE enteritis.
