Incidental findings on FDG-PET/CT in large vessel vasculitis
This study aims to determine the number and type of incidental findings detected on positron emission tomography (PET)/CT in a cohort of patients with large vessel vasculitis (LVV). Reports from PET/CT studies along with the medical charts of a cohort of patients with LVV from a Rheumatology clinic in Edmonton, Alberta, Canada, were retrospectively reviewed. Incidental findings from PET/CT, along with follow-up studies and their diagnosis were documented. The data was analyzed with descriptive statistics. The disease activity of 40 patients, with an average age of 65.8 years, was investigated using PET/CT. A statisticall...

Transcriptomic analysis reveals the potential biological mechanism of AIS and lung adenocarcinoma
DiscussionOur findings suggest that the hub genes we found in this study contribute to the development and progression of AIS and LUAD by altering the cellular senescence pathway. Thus, they may be promising markers for diagnosis and prognosis.

Stroke and cancer
Rev Neurol (Paris). 2023 Apr 4:S0035-3787(23)00891-3. doi: 10.1016/j.neurol.2023.03.009. Online ahead of print.ABSTRACTAssociation between stroke and cancer is well-established and has led to a growing literature over the past decades. Risk of ischemic and hemorrhagic stroke is increased among patients with newly diagnosed cancer and 5-10% of stroke patients bear an active cancer. All cancers are concerned, but hematological malignancy in childhood and adenocarcinoma from lung, digestive tract and pancreas in adults are most usually identified. Unique stroke mechanisms are dominated by hypercoagulation, a condition that ma...

Differentially Expressed Genes Analysis in the Human Small Airway Epithelium of Healthy Smokers Shows Potential Risks of Disease Caused by Oxidative Stress and Inflammation and the Potentiality of Astaxanthin as an Anti-Inflammatory Agent
This study aims to observe differentially expressed genes (DEGs) in the human small airway epithelium of smokers compared to genes whose expression changes due to astaxanthin (AST) treatment, an antioxidant compound that can modulate Nrf2. Gene expression data that was stored in the GEO browser (GSE 11952) was analyzed using GEO2R to search for DEG among smokers and nonsmokers subject. DEG was further compared to those genes whose expression changes due to astaxanthin treatment (AST) that were obtained from the Comparative Toxicogenomics Database (CTD; https://ctdbase.org/). DEG (p < 0.05) analysis result shows that the...

Clinical characteristics of pancreatic and biliary tract cancers in Lynch syndrome: A retrospective analysis from the Finnish National Lynch Syndrome Research Registry
ConclusionAlthough the survival of LS patients with PC or BTC is better than in sporadic cancers, it is still poor and may be reflected by the relatively higher surgical resectability accounted for by the earlier age of onset. More studies on analyses of the molecular and immune profile, screening, and management of LS-associated pancreaticobiliary cancers are warranted.

E-164 Recurrent strokes as the initial presentation of colorectal adenocarcinoma
ConclusionCryptogenic strokes in patients with cancer are cardioembolic manifestations of cancer-mediated hypercoagulability such as NBTE, which consists of sterile, platelet-fibrin vegetations on cardiac valves. The mechanism of thromboembolism in patients with cancer is based on the interaction between tumor cells and leukocytes, which creates a thrombogenic vascular lining and induces the release of substances that activate the coagulation cascade. The diagnosis of NBTE should depend on the distribution of occluded vessels, identification of thrombus, and exclusion of other possible causes such as infective endocarditis...

267 When investigating stroke is a waste of time
Young stroke should alert clinicians to investigate for unusual causes.
A previously well 43-year-old Caucasian female presented with 2 days of punctuated left sided weakness and sensory inattention. MRI demonstrated multiple territory infarcts, predominantly on the right side. With no vascular risk factors, high dose steroids were commenced assuming primary angiitis of the CNS (PACNS). Blood tests including ESR, HIV, an autoimmune and thrombotic screen and blood cultures were negative. A 24-hour ECG and TOE failed to identify an embolic source, though interval MRIs plus CT angi- ography revealed evolving cerebral and sple...

Anticoagulation for atrial fibrillation in active cancer
Oncol Lett. 2022 Apr;23(4):124. doi: 10.3892/ol.2022.13244. Epub 2022 Feb 17.ABSTRACTAtrial fibrillation (AF) may often pre-exist in patients with newly diagnosed cancer or occur with increased frequency shortly after cancer diagnosis. Patients with active cancer and AF have a particularly high risk of thromboembolic complications, as both conditions carry a risk of thrombosis. Thromboembolic risk is determined by several factors, including advanced age, sex (females), cancer histology (adenocarcinomas), location (e.g., pancreas, stomach), advanced stage, anticancer regimens (e.g., platinum compounds, anti-angiogenic thera...
