“…AEF formation in other regions of the GI tract is less common because a fixed structure is necessary for fistula establishment, whereas the small and large intestines are mobile. The fistula observed in our patient occurred between the fourth segment of the duodenum and the infrarenal aorta, rendering this case particularly unusual [ 4 , 9 ].…”

“…Due to its uncommon clinical presentation, diagnosing and treating primary AEF can be challenging, despite advancements in imaging and endoscopic technologies. Symptoms may include hemodynamic instability and significant gastrointestinal bleeding, presenting as hematemesis, melena, rectorrhagia, or a combination of these manifestations [ 4 , 5 ].…”

“…Around 70% of patients present with GI bleeding, known as a “herald bleed,” which resolves spontaneously due to vasospasm and clot formation, often followed by massive hemorrhage within hours to months [ 4 , 5 ]. The clinical progression can be very rapid, preventing adequate diagnostic tests such as endoscopy or CT from determining the cause of the GI bleeding [ 9 ].…”

A primary aortoenteric fistula is a rare clinical entity that leads to severe upper gastrointestinal bleeding and carries a high risk of mortality, yet diagnosing aortoenteric fistulas remains challenging. Diagnosis is frequently delayed due to the uncommon and non-specific nature of the abdominal signs and symptoms. Rapid diagnosis and prompt surgical intervention are paramount to the successful management of this condition which is known for its profoundly poor prognosis. This report describes two cases of primary aortoenteric fistulas, one of which presented with melena and hematemesis, and the other presented with hematemesis and abdominal pain. In both cases, computed tomography angiography (CTA) demonstrated findings suggestive of an aortoenteric fistula, namely, locules of gas within the aortic lumen, which led to emergent surgical intervention. One patient underwent esophagogastroduodenoscopy while in the operating room before surgical intervention. One patient underwent repair with axillo-bifemoral bypass and the other with juxtarenal abdominal aortic aneurysm repair with a rifampin-soaked gelsoft dacron graft followed by primary bowel repair. Postoperative complications for one of the patients included duodenal repair breakdown as well as colonic ischemia. One patient made a meaningful recovery and remained without complications until the first postoperative visit two months after the repair. The other patient was discharged and then subsequently lost to follow-up. The two patients’ successful outcomes of such a lethal condition were in large part due to rapid diagnosis with CTA and prompt surgical intervention.

Time series analysis is a valuable tool in epidemiology that complements the classical epidemiological models in two different ways: Prediction and forecast. Prediction is related to explaining past and current data based on various internal and external influences that may or may not have a causative role. Forecasting is an exploration of the possible future values based on the predictive ability of the model and hypothesized future values of the external and/or internal influences. The time series analysis approach has the advantage of being easier to use (in the cases of more straightforward and linear models such as Auto-Regressive Integrated Moving Average). Still, it is limited in forecasting time, unlike the classical models such as Susceptible-Exposed-Infectious-Removed. Its applicability in forecasting comes from its better accuracy for short-term prediction. In its basic form, it does not assume much theoretical knowledge of the mechanisms of spreading and mutating pathogens or the reaction of people and regulatory structures (governments, companies, etc. ). Instead, it estimates from the data directly. Its predictive ability allows testing hypotheses for different factors that positively or negatively contribute to the pandemic spread; be it school closures, emerging variants, etc. It can be used in mortality or hospital risk estimation from new cases, seroprevalence studies, assessing properties of emerging variants, and estimating excess mortality and its relationship with a pandemic.
