    Abstract Heart failure (HF) is a clinical syndrome with symptoms and or signs caused by a structural and/or functional cardiac abnormality and associated with elevated natriuretic peptide levels and/or objective evidence of pulmonary or systemic congestion. It is classified according to left ventricular ejection fraction (LVEF): HF with reduced EF (HFrEF) with an LVEF of ≤40%, HF with mildly reduced EF (HFmrEF) with an LVEF of 41 to 49%, HF with preserved EF (HFpEF) with an LVEF of ≥50%, and HF with improved EF (HFimpEF) with a baseline LVEF of ≤40%, a ≥ 10% increase from baseline LVEF, and a second measurement of LVEF of >40%. Despite the remarkable progress in the management of HF over the past decades, its prognosis is still poor with higher rates of mortality and hospitalization due to worsening HF. Therefore, the development of novel strategies including pharmacologic therapy is needed to further improve its prognosis. Recent large-scale clinical trials have demonstrated the efficacy of newer pharmacological agents including angiotensin II receptor/neprilysin inhibitor (ARNI), sacubitril/valsartan, type 2 sodium-glucose cotransporter (SGLT2) inhibitors, dapagliflozin, empagliflozin and sotagliflozin, and soluble guanylyl cyclase (sGC) stimulator, vericiguat, and cardiac myosin activator, omecamtiv mecarbil. This review focuses the recent advances in the pharmacological agents for treatment of chronic heart failure, including their mechanisms of action, the evidence based on the clinical trials, and the guideline recommendations for their use.

    Abstract The leukemoid reaction (LR) is reported to be caused by severe stress conditions such as infection, malignancies, intoxication, severe hemorrhage, or acute hemolysis; this condition is attributed to a very severe prognosis. Some reports have suggested that the LR was associated with a systemic stress response. A 36-year-old man who required mechanical circulatory support (MCS), including veno-arterial extracorporeal membrane oxygenation and Impella 5.5 due to severe heart failure, was transferred to our hospital. He showed a markedly elevated WBC count and died of multiple organ failure. The autopsy revealed the possibility that leukocytosis might have been due to an LR; however, the cause of the cardiac failure was unknown. To the best of our knowledge, this study is the first to report a rare case of LR in a patient with severe heart failure requiring MCS.

    Abstract Introduction: During stent grafting, managing the internal iliac artery (IIA) becomes a significant issue when an abdominal aortic aneurysm (AAA) is complicated by bilateral common iliac artery (CIA) aneurysms. The iliac branch system (IBS) has a defined length; therefore, the CIA should be sufficiently long. However, situations arise where the IBS must be used even in patients with a short CIA. A case of contralateral CIA occlusion due to deviation of the proximal iliac branched component of the IBS is reported.
    Report: A 73 year old man underwent stent grafting with inferior mesenteric artery coil embolisation and IBS for a 70 mm AAA and >30 mm bilateral CIA aneurysm. As standard procedure, the right iliac branched component and the internal iliac component were used. After removing the guidewire used for deploying the internal iliac component, the left 12 Fr Dryseal and guidewire were pulled down. The proximal end of the right iliac branched component deviated over the left CIA origin, resulting in CIA occlusion. As a solution, a 12 Fr Dryseal was inserted with a dilator and guidewire in the 16 Fr Dryseal from the left side, following which the tip of the 12 Fr Dryseal dilator was used to push the iliac branched component to create a gap. The guidewire was successfully inserted, and the surgery was subsequently completed as planned. The post-operative course of the patient was uneventful.
    Conclusion: When deploying an iliac branched component in cases where the CIA is shorter than the length of the component, it is crucial to place the contralateral guidewire into the aorta before pulling down the contralateral sheath. The iliac branched component may follow the pull through wire and occlude the contralateral CIA. Furthermore, if the element occludes the contralateral CIA, it can be managed using this method.

    Abstract Superior mesenteric artery (SMA) aneurysms (SMAAs) are rare and account for approximately 7% of all visceral artery aneurysms. If the anatomical complexity permits and the patency of organ perfusion is allowed, then an endovascular approach is the first choice for minimally invasive procedures. We report the case of a 92-year-old female with a giant SMAA and challenging anatomy, including a short proximal sealing zone from the origin of the SMA and a short distal sealing zone from the hepatic artery bifurcation. In view of her advanced age, she was treated endovascularly with covered stents. Reintervention was required to correct a postoperative endoleak; however, a favorable outcome was achieved with endovascular therapy.

    Abstract Food allergies (FAs) are caused by a failure of the immune system to regulate oral tolerance (OT). The use of soap containing hydrolyzed wheat overrides acquired OT to wheat through skin exposure. However, in mouse models, the experimental OT is robust, suggesting that acquired OT to allergens prevents the development of FAs. We aimed to analyze the mechanisms and developed a mouse model of FA that overrides acquired OT via skin exposure. Three murine FA models (intraperitoneal [IP], epicutaneous [EC], and intradermal [ID]) were compared to evaluate if allergies to ovalbumin (OVA) that had been previously tolerated orally could be induced. In the ID model, OT was overridden, and allergic reactions of severe anaphylaxis were developed. To analyze this effect in the ID model, we measured the migration of dendritic cells (DCs) into lymph nodes. The induction of OT promoted the migration of CD103
