Corona virus disease (COVID-19) initially appeared to be an exclusively respiratory ailment. While that is true in a vast majority of the cases, its evolution and later evidence have shown that it can afflict virtually any organ system in the human body after first gaining entry through the respiratory tract. The COVID-19 vaccines were one of the turning points in the campaign to control the COVID-19 pandemic. However, after their extensive use all over the world, it has emerged that they can cause some dangerous collateral damage. We, herein, report the case of a 58-year-old woman who presented to us with signs and symptoms of acute intestinal obstruction 4 months after receiving her first dose of Covishield vaccination for COVID-19. Her blood tests showed a high D-dimer and normal platelet count. She was previously admitted to the hospital with an acute abdomen 3 months back. A contrast-enhanced computed tomography (CECT) scan of the abdomen done then had revealed thrombi in the aorta and inferior mesenteric and splenic arteries. She was started on low-molecular-weight heparin and discharged on tablet Warfarin after clinical improvement. CECT abdomen done during her present admission revealed a proximal small bowel stricture with dilated proximal and collapsed distal loops. She underwent a laparoscopic jejuno-ileal resection anastomosis. During the post-operative period, a repeat CECT abdomen done to evaluate multiple episodes of vomiting revealed pulmonary embolism in the lower chest cuts. A venous Doppler revealed extensive deep venous thrombosis of the left lower limb. A thrombophilia profile diagnosed anti-phospholipid antibody syndrome, an exacerbation of which was likely precipitated by the COVID-19 vaccine.

Antiphospholipid syndrome (APS) is a systemic autoimmune syndrome characterized by arterial or venous thrombosis, pregnancy complications and thrombocytopenia. The aim of this study is to investigate the association between APS and atrial fibrillation (AF) among patients in Peking University People's Hospital. A single center retrospective study was conducted. Cases were hospitalized patients diagnosed with AF by a cardiologist while the control group patients did not exhibit cardiac diseases. The results of the study revealed that in multivariable logistic regression, APS, anticardiolipin antibody (aCL) positivity and anti-beta-2-glycoprotein antibody (anti-2GPI) positivity are independent risk factors of AF. APS, aCL positivity and anti- GPI positivity are statistically different between AF patients and non-AF patients. Forthcoming studies are needed to clarify the potential link between APS and AF.

BACKGROUND
Portal vein arterialization (PVA) has been used in liver transplantation (LT) to maximize oxygen delivery when arterial circulation is compromised or has been used as an alternative reperfusion technique for complex portal vein thrombosis (PVT). The effect of PVA on portal perfusion and primary graft dysfunction (PGD) has not been assessed.
AIM
To examine the outcomes of patients who required PVA in correlation with their LT procedure.
METHODS
All patients receiving PVA and LT at the Fundacion Santa Fe de Bogota between 2011 and 2022 were analyzed. To account for the time-sensitive effects of graft perfusion, patients were classified into two groups: prereperfusion (pre-PVA), if the arterioportal anastomosis was performed before graft revascularization, and postreperfusion (post-PVA), if PVA was performed afterward. The pre-PVA rationale contemplated poor portal hemodynamics, severe vascular steal, or PVT. Post-PVA was considered if graft hypoperfusion became evident. Conservative interventions were attempted before PVA.
RESULTS
A total of 25 cases were identified: 15 before and 10 after graft reperfusion. Pre-PVA patients were more affected by diabetes, decompensated cirrhosis, impaired portal vein (PV) hemodynamics, and PVT. PGD was less common after pre-PVA (20.0% 60.0%) ( = 0.041). Those who developed PGD had a smaller increase in PV velocity (25.00 cm/s 73.42 cm/s) ( = 0.036) and flow (1.31 L/min 3.34 L/min) ( = 0.136) after arterialization. Nine patients required PVA closure (median time: 62 d). Pre-PVA and non-PGD cases had better survival rates than their counterparts (56.09 months 22.77 months and 54.15 months 31.91 months, respectively).
CONCLUSION
This is the largest report presenting PVA in LT. Results suggest that pre-PVA provides better graft perfusion than post-PVA. Graft hyperperfusion could play a protective role against PGD.

BACKGROUND
Postoperative atrial fibrillation (POAF) is one of the most common types of acute AF and can complicate the treatment course of approximately one third of patients undergoing cardiac surgery. Sodium-glucose cotransporter-2 (SGLT2) inhibitors are among the newest antidiabetic drugs which can be therapeutic options for preventing POAF by different mechanisms.
METHODS
Empagliflozin to Prevent POAF (EMPOAF) is an interventional, investigator-initiated, double-blind, placebo-controlled, multicenter, randomized controlled trial which will be conducted in two referral teaching cardiology hospitals in Tehran. Four-hundred ninety-two adult patients who are scheduled for elective isolated coronary artery bypass graft (CABG) surgery will be randomly assigned to one of the groups of intervention (empagliflozin 10 mg daily) or placebo starting at least 3 days before surgery until discharge. Key exclusion criteria are a history of diabetes mellitus, AF, ketoacidosis, or recurrent urinary tract infections along with severe renal or hepatic impairment, unstable hemodynamics, and patients receiving SGLT2 inhibitors for another indication. The primary outcome will be the incidence of POAF. Key secondary endpoints will be the composite rate of life-threatening arrhythmias, postoperative acute kidney injury, hospitalization length, in-hospital mortality, stroke, and systemic embolization. Key safety endpoints will be the rate of life-threatening and/or genitourinary tract infections, hypoglycemia, and ketoacidosis.
CONCLUSIONS
EMPOAF will prospectively evaluate whether empagliflozin 10 mg daily can reduce the rate of POAF in patients undergoing elective CABG. Enrolment into this study has started by November 2023 and is expected to be ended before the end of 2025.

Retransplantation has been the primary treatment for Hepatic artery thrombosis (HAT) in Orthotopic Liver Transplant (OLT) patients; however, due to scarcity of grafts, endovascular revascularization via mechanical thrombectomy offers an alternative to re-transplantation should it provide similar long term benefits. A series of 8 patients with hepatic artery thrombectomies across 10 procedures (1 Early HAT and 9 Late HAT) utilizing stent-retriever and/or suction catheter was collected. All had technically successful restoration of flow with stent placement of the anastomotic stenosis in 8 cases. Two patients required re-intervention for HAT at 18 and 701 days post-primary intervention, with the first expiring from liver failure but with a patent hepatic artery on explant. One case had a procedural related adverse event, hepatic artery dissection, SIR AE classification of 2. Technical success was achieved in all procedures, demonstrating promise in effectively treating HAT in OLT patients.

INTRODUCTION AND IMPORTANCE
Congenital gangrene of the limb in a newborn child is an extremely rare pathology with polyetiological causes that has not been fully studied. Therefore, each case of this pathology has its own characteristics of manifestations and allows you to get closer to solving this problem.
CASE PRESENTATION
We present a clinical case of congenital gangrene of the right upper limb in a newborn child. Analysis of the newborn baby's medical history indicated gestational hypertension and pyelonephritis during pregnancy in the mother, hemostasis disorders in the newborn. Computed tomography (CT) of the vessels of the right upper limb and thoracic segment confirmed brachial artery thrombosis. At the initial stage, conservative treatment was carried out, which included preventive antibacterial therapy and local care of the affected area. Only after a clear delineation of the dead tissue, the amputation of the segment of the right upper limb was performed. Amputation was performed with preservation of the proximal growth zone in order to provide an adequate stump for subsequent prosthetics.
CLINICAL DISCUSSION
Adverse factors during pregnancy can cause increased thrombosis. Through fetal communications, blood clots from the right atrium can enter the left atrium, the left ventricle and further into the large circulatory circle and cause thrombosis of the artery of the right upper limb. Another factor of increased thrombosis is congenital intrauterine infection of the newborn. Conservative treatment is carried out after diagnosis until the final determination of the boundaries of gangrene. When performing amputation, it is important to preserve the proximal bone growth zone in order to form an adequate stump for prosthetics.
CONCLUSION
Congenital gangrene of the limb in a newborn child is an extremely rare pathology. Irreversible changes in the upper limb in the child were caused by a combination of two factors: gestational hypertension and pyelonephritis in a pregnant woman and hemostasis disorders in a newborn due to intrauterine infection. Therefore, the preparation of women for pregnancy, examination for intrauterine infection and treatment of extragenital pathology are important in the prevention of this disease.

True aneurysm of the radial artery is very rare. Aneurysmal expansion of arteries due to degenerative changes, possibly infections, primarily affects the abdominal and thoracic aorta, intra and extracranial sections of cerebral arteries, popliteal artery, and visceral arteries. Published literature does not address the aneurysm on the distal sections of the arteries of upper or lower limb. Unlike the classic symptoms of aneurysmally altered arteries such as rupture, thrombosis and embolization, we encounter more often vascular compression syndrome in distal peripheral aneurysms. We demonstrate the case management of a patient with over 20 years increasing wrist resistance. A fusiform aneurysm of the distal section of the radial artery was identified by sonography. Under general anesthesia, we performed aneurysm resection and artery reconstruction using an interpositum from the ipsilateral cephalic vein. The histological examination of the resected tissue confirmed the presence of all three layers of the vascular wall, confirming the true aneurysm of the radial artery. No complications developed in the patient in the postoperative period and all problems related to the aneurysm subsided (Fig. 4, Ref. 23). Keywords: aneurysm, arteria radialis, surgical reconstruction.

BACKGROUND
Mesenteric arterial thrombosis is an extremely rare thrombotic event, especially during pregnancy, that can cause rapid fatal consequences unless the patient receives early definitive treatment.
CASE PRESENTATION
We report the case of a 34-year-old female presenting in her seventh week of gestation with severe abdominal pain who was promptly diagnosed with mesenteric artery occlusion amidst incipient miscarriage. The patient underwent a successful mesentery artery embolectomy, recovered and was later diagnosed with elevated factor VIII activity.
CONCLUSION
The diagnosis of mesenteric ischemia should be considered in pregnant women presenting with severe abdominal pain and any prior predisposing factors. Our case highlights the pivotal role of the emergency physician in maintaining a high index of suspicion coupled with timely and determined action. The prognosis of this high mortality condition depends on prompt diagnosis, early definite management and successful multidisciplinary cooperation.
