The level of CHB virus (HBV) core antibody (HBcAb) is different in four stages of chronic HBV infection and may be used for differential diagnosis of the natural history of chronic HBV infection. To address this question, we examined multiple blood biomarkers and assessed the efficacy to diagnose different stages of chronic HBV infection. The quantitative detection of HBcAb, hepatitis B surface antigen (HBsAg), HBV DNA, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and platelet count (PLT) were determined in the serum of 73 cases of low-replicative phase (LR), 46 cases of immune-tolerant phase (IT), 44 cases of immune clearance phase (IC), and 57 cases of HBeAg-negative hepatitis (ENH). Differentiating performance of these serum protein levels was analyzed by receiver operating characteristic (ROC) curve analysis. Our results showed that the levels of HBcAb, ALT, and AST levels were significantly higher in IC and ENH than those in LR and IT (both P ≤ 0.001). The levels of HBV DNA and HBsAg were higher in IC and IT than those in LR and ENH (both P ≤ 0.001). Logistic regression models showed that HBcAb, HBsAg, HBV DNA, ALT, and AST were the independent variables, respectively, and when combined, they provided high diagnostic accuracy for the staging of CHB. To sum up, HBcAb quantification is a new index, which can reflect whether the liver is in the immune activation state of HBV infection, and is related to the inflammatory state of the host liver. The combined detection of HBcAb quantification and other indicators has showed promising efficiency for staging of IC and ENH and can assist the diagnosis and treatment of CHB.Among the different types of cancers, lung cancer is one of the widespread diseases which causes the highest number of deaths every year. The early detection of lung cancer is very essential for increasing the survival rate in patients. Although computed tomography (CT) is the preferred choice for lungs imaging, sometimes CT images may produce less tumor visibility regions and unconstructive rates in tumor portions. Hence, the development of an efficient segmentation technique is necessary. In this paper, water cycle bat algorithm- (WCBA-) based deformable model approach is proposed for lung tumor segmentation. In the preprocessing stage, a median filter is used to remove the noise from the input image and to segment the lung lobe regions, and Bayesian fuzzy clustering is applied. In the proposed method, deformable model is modified by the dictionary-based algorithm to segment the lung tumor accurately. In the dictionary-based algorithm, the update equation is modified by the proposed WCBA and is designed by integrating water cycle algorithm (WCA) and bat algorithm (BA).Isolated spontaneous dissection of the mesenteric artery in the absence of involvement of the aorta or its branches is an uncommon vascular entity. It is generally seen in males and presents with gastrointestinal symptoms due to mesenteric ischemia. However, asymptomatic cases are increasingly being diagnosed due to increased use of computed tomography (CT) angiography. The course is usually self-limiting, and conservative management with bowel rest, strict blood pressure control, anticoagulants, sedatives for pain, and close observation usually suffices. Surgery or endovascular stenting is usually reserved for those exhibiting bowel ischemia or impending rupture. We report a case of a young female with isolated spontaneous mesenteric artery dissection with thrombus, which did not improve with medical therapy and was managed promptly by surgery due to the presence of bowel ischemia.Aortic procedures are associated with higher risks of bleeding, yet data regarding perioperative transfusion in this patient population are lacking. We evaluated transfusion patterns in patients undergoing proximal aortic surgery to provide a benchmark against which future standards can be assessed. Between June 2014 and July 2017, 247 patients underwent elective aortic reconstruction for aneurysm. Patients with acute aortic syndrome, endocarditis, and/or prior cardiac surgery were excluded. Transfusion data were analyzed by type of operation ascending aorta replacement ± aortic valve procedure (group 1, n  = 122, 49.4%); aortic root replacement with a composite valve-graft conduit ± ascending aorta replacement (group 2, n  = 93, 37.7%); valve-sparing aortic root replacement (VSARR) ± ascending aorta replacement (group 3, n  = 32, 13.0%). Thirty-day mortality for the entire cohort was 2.02% (5 deaths). Overall, 75 patients (30.4%) did not require any transfusion of blood or other products. Patients in groups 1 and 3 were significantly more likely to avoid transfusion than those in group 2. Mean transfusion volume for any individual patient was modest; those who underwent VSARR (group 3) required less intraoperative red blood cells (RBC) than others. Intraoperative transfusion of RBC was independently associated with an increased risk of death at 30 days. Elective proximal aortic reconstruction can be performed without the need for excessive utilization of blood products. Composite root replacement is associated with a greater need for transfusion than either VSARR or isolated replacement of the ascending aorta.Restless leg syndrome (RLS) is a common cause of lower extremity discomfort. We hypothesized that patients with RLS symptoms have higher rates of deep and superficial venous reflux (SVR). Retrospective review of patients ≥18 years of age evaluated in a venous center from December 2018 to February 2019. Differences in rates of RLS symptoms, demographics, comorbidities, and clinical and radiologic presence of venous disease were analyzed. Overall, 207 patients were analyzed; 140 (67.6%) reported RLS symptoms ( n  = 25 with prior RLS diagnosis). RLS symptoms were more common with superficial or combined superficial and deep venous reflux (DVR) compared with those without reflux ( p   0.05) but increased rates of venous pain, phlebitis, family history of venous disease, lower extremity swelling and SVR, and combined SVR and DVR (all p   less then  0.05). Our multivariable logistic regression found presence of SVR, and family history of venous reflux was associated with RLS symptomatology (all p   less then  0.001). see more Ninety-nine patients with RLS underwent ablation; of them, 93 had duplex-proven reflux resolution of which 81 (87%) reported RLS symptom improvement. This included 13 of 16 (81.3%) with prior RLS diagnosis. SVR is associated with increased rates of RLS symptoms in a vein center population. Therefore, RLS symptoms should trigger a targeted venous evaluation. Our results suggest that venous ablation may lead to resolution of RLS symptoms in patients with SVR, but randomized prospective trials with strict RLS definition criteria are warranted to confirm these outcomes.Coronary artery fistula (CAF) in adults is a rare but significant coronary artery anomaly. Main data on that rare disease were mostly obtained from case reports and small studies. In presented study, we share our two-decade experience on the clinical and angiographic characteristics of CAF. The data were collected retrospectively by analyzing the angiographic data between January 1, 2000 and December 31, 2019. Demographic data, clinical data, laboratory, and cardiac catheterization reports were reviewed. CAFs were found in 40 patients (0.06%). There were 22 male (55%) patients. The mean age was 61.2 years. Twenty-nine patients (72.5%) had small, 4 patients (10%) had medium, and 7 patients (17.5%) had large CAFs. The majority of study population had solitary CAF ( n  = 31, 77.5%). The pulmonary artery is the major side of fistula drainage ( n  = 20, 50%). The study population was divided into two groups as follow group 1-small CAFs 29 (72.5%), group 2-medium and large CAF (MLCAF) 11 (27.5%). Patients with MLCAFs had more atrial fibrillation, abnormal coronary morphology, and multiple fistulae. In patients with hemodynamically significant CAFs, 7 (17.5%) patients had surgical ligation and 3 (7.5%) patients had transcutaneous closure. Three patients died during mean follow-up period of 5 years. The incidence and the pattern of CAFs in our study were similar to previous studies. Clinical course of small fistulae was benign. Symptomatic MLCAFs need to be treated by transcatheter or surgical way and should be individualized per patient.A total of 15 to 20% of deaths worldwide are sudden (within 1 hour of symptom onset). Our ability to predict and prevent sudden cardiac death (SCD) in the general population, in which 85% have no known organic heart disease (OHD) or stable OHD with left ventricular ejection fraction >40%, is limited to poor. The purpose of this commentary is to suggest a new approach to SCD in this population. Oxidative stress is a common thread in development and progression of the major cardiac diseases associated with SCD. It has a profound adverse effect upon heart rate variability (HRV), sympathetic tone (S), and parasympathetic tone (P). Recently, developed technology finally has allowed accurate measures of S and P. Using this technique, the general population can be screened, those at risk for SCD can be identified with a higher degree of success, and preventative measures instituted. For example, in 133 geriatric type 2 diabetics with S and/or P abnormalities upon screening, the potent and natural antioxidant (r)α lipoic acid reduced SCD (relative risk reduction) 43% ( p  = 0.0076), mean follow-up 6.31 years. Diabetes mellitus patients have high glycemic oxidative stress. Addressing oxidative stress S and P abnormalities can reduce SCD. S and P screening of the general population will be discussed.Cardiovascular (CV) disease is the leading cause of premature death in ankylosing spondylitis (AS). Atherosclerosis and AS share similar pathogenic mechanisms. The proven benefits of angiotensin-receptor blockers (ARBs) in atherosclerotic cardiovascular disease and their role in immune mediation provide strong rationale to investigate its impact with olmesartan on inflammation and endothelial dysfunction in AS. To investigate the effect of olmesartan on inflammation and endothelial dysfunction in AS. 40 AS patients were randomized to receive 24 weeks of treatment with olmesartan (10 mg/day, n  = 20) and placebo ( n  = 20) as an adjunct to existing stable antirheumatic drugs. Markers of endothelial function included the following flow-mediated dilation (FMD) assessed by AngioDefender, endothelial progenitor cells (EPCs) estimated by flow cytometry, nitrite (nitric oxide surrogate), intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) and inflammatory measures including Bath placebo. HAQDI and SF-36 (PH) scores improved significantly in olmesartan group as compared with placebo. Olmesartan reduces inflammatory disease activity, improves quality of life (QOL), and decreases CV risk demonstrating the immunomodulatory, vasculoprotective, and cardioprotective potential of this drug in AS.The prevalence of diabetes mellitus continues to increase from year to year. Critical limb ischemia (CLI) is one of the complications of diabetes mellitus with a high mortality rate and requires amputation if not treated properly. Mean platelet volume (MPV) is an indicator of platelet activation and is expected to be a predictor of CLI in diabetes mellitus patients. This article investigates the relationship between MPV and the incidence of CLI in diabetes mellitus patients. This case-control study was conducted using the vascular registry of Dr. Sardjito Hospital, Yogyakarta, Indonesia, from January 2016 to December 2016. The relationship between MPV and the incidence of CLI was analyzed using bivariate and multivariate analysis. There was a significant association between MPV and incidence of CLI in diabetes mellitus patient both on bivariate analysis ( p  = 0.035) and multivariate analysis ( p  = 0.029). Diabetes mellitus patients with MPV values of ≥ 9.8 fl had a protective effect to prevent the incidence of CLI (bivariate analysis odds ratio [OR] = 0.
