Mitral annular disjunction (MAD) is routinely diagnosed by cardiac imaging, mostly by echocardiography, and shown to be a risk factor for ventricular arrhythmias. While MAD is associated with mitral valve (MV) prolapse (MVP), it is unknown which patients with MAD are at higher risk and which additional imaging features may help identify them. The value of cardiac computed tomography (CCT) for the diagnosis of MAD is unknown. Accordingly, we aimed to (1) develop a standardized CCT approach to identify MAD in patients with MVP and severe mitral regurgitation (MR); (2) determine its prevalence and identify features that are associated with MAD in this population. We retrospectively studied 90 patients (age 63 ± 12 years) with MVP and severe MR, who had pre-operative CCT (256-slice scanner) of sufficient quality for analysis. The presence and degree of MAD was assessed by rotating the view plane around the MV center to visualize disjunction along the annulus. Additionally, detailed measurements of MV apparatus and left heart chambers were performed. Univariate logistic regression analysis was performed to determine which parameters were associated with MAD. MAD was identified in 18 patients (20%), and it was typically located adjacent to a prolapsed or flail mitral leaflet scallop. Of these patients, 75% had maximum MAD distance > 4.8 mm and 90% > 3.8 mm. Female gender was most strongly associated with MAD (p = 0.04). Additionally, smaller end-diastolic mitral annulus area (p = 0.045) and longer posterior leaflet (p = 0.03) were associated with greater MAD. No association was seen between MAD and left ventricular size and function, left atrial size, and papillary muscle geometry. CCT can be used to readily detect MAD, by taking advantage of the 3D nature of this modality. A significant portion of MVP patients referred for mitral valve repair have MAD. The presence of MAD is associated with female gender, smaller annulus size and greater posterior leaflet length.Delayed cardiac tamponade (DCT) can be a fatal complication after cardiac surgery, but its early diagnosis and/or prediction is sometimes difficult. This study aimed to confirm the efficacy of postoperative computed tomography (CT) as routine examination compared with transthoracic echocardiography (TTE) for predicting DCT after cardiac surgery. This study was a retrospective single-center analysis of 485 consecutive patients undergoing cardiac surgery from January 2016 to July 2018 in our department. Among them, 237 patients were enrolled in this analysis after application of the exclusion criteria minimally invasive surgery via small thoracotomy, death in the acute phase, and no CT 7 ± 3 days after surgery. Pericardial effusion (PE) was measured at the thickest part using CT and TTE. DCT was found in nine enrolled patients (3.8%). The mean PE on CT was 7.7 ± 5.5 mm in the no event group and 23.4 ± 5.7 mm in the DCT group (p = 0.026), whereas the mean PE on TTE was 6.2 ± 4.5 mm in the no event group and 10.8 ± 4.4 mm in the DCT group (p = 0.170). CBL0137 p53 activator On multivariate analysis, PE greater than 20 mm on CT (Odds ratio, 13.93; 95% confidence interval 2.57-75.46; p = 0.002) was a significant predictor of DCT. The present study suggested that postoperative CT examination is superior to TTE for predicting DCT. If PE is less than 20 mm on CT, it could be treated conservatively; otherwise, preventive/therapeutic intervention should be considered.The present in vitro study was conducted to investigate the effect of low-level laser (LLL) radiation and doxycycline on the levels of osteoprotegerin (OPG) and receptor activator of nuclear factor kappa-B ligand (RANKL) derived from MG-63 osteosarcoma cell line. MG-63 cells were divided into four groups. CBL0137 p53 activator In the first group, 2 mg/mL of doxycycline was injected into the cell culture medium. Diode laser (810 nm, 100 mw, 75 s) was radiated to the culture medium of the second group. The third group received both doxycycline and laser radiation. In the fourth group (control), the culture medium was replaced daily, similar to the above three groups. Mentioned interventions were performed once a day for 4 consecutive days. Then, on the sixth day, the levels of OPG and RANKL mediators were measured using real-time polymerase chain reaction by isolating the cells from the samples. OPG expression had the highest to lowest levels in the laser + doxycycline, doxycycline, laser, and control groups, respectively. The level of OPG was significantly different between all the study groups (p  0.05). The results of this study revealed that LLL and doxycycline reduced the RANKL/OPG ratio derived from the MG-63 osteosarcoma cell line, which may result in the diminished activity of osteoclasts and osteoclastogenesis.The study examined immigration factors associated with depressive symptom severity among Asian American immigrants. Participants were 458 Chinese, Korean and Vietnamese adults. Depressive symptom severity was measured by PHQ-9. Overall, the likelihood of being moderately to severely depressed was significantly increased among immigrants living in the US for  less then  10 years and Korean Americans compared to Chinese Americans. However, mild level of depressive symptoms was not associated with any immigration-related factors. The positive impact of shorter duration of living in the US and a younger age at immigration (≤ 17) on depressive symptoms was evident among women but not among men. For men, marital status and education level were significant predictors of being moderately to severely depressed. Differentiating immigrant factors and identifying depressive symptom severity can help drive community and clinical interventions to detect and treat depression early among Asian American immigrants.The present study aimed to investigate the dynamic process of soybean β-conglycinin in digestion, absorption, and metabolism in the intestine of grass carp (Ctenopharyngodon idella). Fish fed with 80 g β-conglycinin/kg diet for 7 weeks, the intestinal digestive enzyme was extracted to hydrolyze β-conglycinin in vitro, the free amino acid and its metabolism product contents in intestinal segments were analyzed. The present study first found that β-conglycinin cannot be thoroughly digested by fish intestine digestive enzyme and produces new products (about 60- and 55-kDa polypeptides). The indigestible β-conglycinin further caused the free amino acid imbalance, especially caused free essential amino acid deficiency in the proximal intestine but excess in the distal intestine. Moreover, these results might be partly associated with the effect of β-conglycinin in amino acid transporters and tight junction-regulated paracellular pathway. Finally, dietary β-conglycinin increased the content of amino acid catabolism by-product ammonia while decreased the amino acid anabolism product carnosine content in the proximal intestine and distal intestine.
