The purpose of this study is to provide detailed data on treatment persistence and clinical outcomes in Chinese patients with nonvalvular atrial fibrillation (NVAF). A single-center retrospective observational study was conducted. A total of 26,663 NVAF patients were enrolled from January 1, 2014 to December 31, 2017, clinical information of whom were from inpatient and outpatients data system was collected. The 1-year treatment persistence rates of 11,350 dabigatran users were 24.5% in 2014, 36.6% in 2015, 37.7% in 2016 and 51.8% in 2017. The predominant reason of non-persistence patients was the cost of treatment. Incidence rates of all-cause death, ischemic stroke and embolism were 1.99/100 person-years, 2.56/100 person-years and 0.77/100 person-years, respectively. Incidence rates of minor bleeding events, intracranial hemorrhage and gastrointestinal hemorrhage were 10.05/100 person-years, 0.51/100 person-years and 0.85/100 person-years, respectively. In conclusion, it is of importance for Chinese clinicians to know about these information because dabigatran is a relatively new drug in China. Compared with other reported data, patients of this study have (1) lower dabigatran persistence and lower incident rates of all-cause death, systemic embolism, minor bleeding events and gastrointestinal hemorrhage and (2) higher incident rates of ischemic stroke and intracranial hemorrhage.PURPOSE To evaluate different corneal parameters in identifying patients at risk of a hyperopic shift after (DMEK). METHODS This retrospective study included 92 eyes of patients with FECD after DMEK surgery. Pachymetry parameters, various tomographic parameters and densitometry values before and after DMEK were determined using a rotating Scheimpflug system (Pentacam HR, Oculus). For assessing the posterior to anterior corneal curvature relationship, we calculated the RPA (posterior to anterior corneal curvature radii ratio). RESULTS The average keratometry reading of the posterior corneal surface (KmB) increased and the total corneal refractive power (TCRP) decreased significantly after surgery (P  less then  .001). There was a significant difference between the preoperative and postoperative RPA (P  less then  .001) and the posterior Q value (P  less then  .001). The strongest correlation was found between the change in the KmB and the preoperative RPA (Spearman's correlation coefficient = 0.872, P  less then  .001). In the receiver operating characteristic (ROC) analysis, the highest AUC values (for ∆KmB) among the different preoperative parameters tested were obtained for RPA and posterior Q value (Asph. QB) with AUROC (area under the ROC) values of 0.95 and 0.89, respectively. CONCLUSIONS The Q value and the RPA showed the highest correlation with the change in corneal refractive power and the greatest AUC. These parameters could be used as surrogate markers to identify eyes that might be at risk of a greater postoperative hyperopic shift, which would allow more accurate setting of refractive goals.PURPOSE To investigate how cheese wiring affects lacrimal drainage function by quantitative assessment of tear function and punctal dimensions. METHODS Patients who underwent lacrimal passage intubation between January 2017 and September 2018 were enrolled prospectively. Among these patients, those with postoperative cheese wiring who received lacrimal passage intubation in one eye met the criteria for further investigation. The subjective symptoms of epiphora, dimensions of puncta, lower tear meniscus, and tear clearance were assessed postoperatively in both the involved eye and untreated contralateral eye. Punctum dimensions were analysed using the digital slit-lamp image. Tear meniscus and tear clearance were assessed by anterior segment optical coherence tomography. RESULTS Postoperative cheese wiring was observed in 68 of 314 eyes. Among these cases, 36 patients (age 70.5 ± 11.7 years) had cheese wiring only in one eye with the involvement of both puncta in 15 patients (group A) and only the lower punctum in 21 patients (group B). There was no patient with the involvement of only the upper punctum. While tear function of the involved eyes in group B did not differ from that of the untreated eye, it was significantly decreased in group A compared with that in untreated control eyes (p  less then  0.05). The tear clearance rate correlated significantly with the upper punctum dimensions (p  less then  0.05), but not with the lower punctum. CONCLUSION Analysis of cheese wiring after lacrimal passage intubation with tear function demonstrated that the integrity of the puncta and the canaliculus is important for lacrimal drainage.Due to fascinating mechanical and biological characteristics spider silk is of great interest in many research fields. Among the orb-weavers Nephila edulis is one of the species used as source for natural spider silk in laboratories. Under appropriate conditions, animals can be kept and bred easily. This manuscript gives information about the spiders' natural habitat, behavior, and breeding and compares them with the established methods and conditions within a research laboratory. Keeping conditions and methods of rearing are described in detail. Within a keeping facility with reliable supply of food, cannibalism rate is significantly reduced and spiders mate all year long. Cohabitants of the genus Steatoda are routinely found in laboratory keeping. While these small spiders do not pose a threat to Nephila edulis, cellar spiders (family Pholcidae) have to be extracted as they have been observed hunting for Nephila spiders.Results of a preclinical study suggested that the anticonvulsant drug ethosuximide may elicit ketamine-like rapid-acting antidepressant actions. We evaluated the antidepressant efficacy of ethosuximide versus placebo in non-medicated adult patients with major depressive disorder (MDD). This randomized, double-blind, placebo-controlled trial included patients at three mental health centers in China. Eighty eligible adults (aged 18-65 years) met the DSM-5 criteria for MDD. Patients in the acute single study received three doses (500, 1000, or 1500 mg) of ethosuximide or placebo. Patients in the repeated study received ethosuximide (1500 mg/day) or placebo for 2 weeks. The Hamilton Depression Rating Scale (HAM-D), the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Hamilton Anxiety Rating Scale were used to assess antidepressant and antianxiety responses to ethosuximide. No significant reductions in depression and anxiety rating scale scores were observed after a single oral administration of ethosuximide, in comparison with placebo. Furthermore, patients receiving ethosuximide for 2 weeks did not show reductions in depression and anxiety rating scale scores. There were no serious adverse events. Responses to the study's primary and secondary outcome measures, the clinician-rated HAM-D and MADRS, showed no change from baseline to the end of treatment, with either ethosuximide or placebo. These results suggest that ethosuximide does not produce ketamine-like robust antidepressant actions in adult patients with MDD.PURPOSE Live surgical demonstrations are considered an effective educational tool providing a chance for trainees to observe a real-time decision-making process of expert surgeons. No data exists evaluating the impact of live surgical demonstrations on the outcomes of minimally invasive colorectal surgery. This study evaluates perioperative and short-term postoperative outcomes in patients undergoing minimally invasive colorectal surgery in the setting of live surgical demonstrations. METHODS Patients undergoing minimally invasive colorectal surgery which was performed as live surgical demonstrations (the study group) performed between 2006 and 2018 were reviewed. These patients were case-matched with those undergoing operations in routine practice (the control group). The study and control group were compared for intraoperative and short-term postoperative outcomes. RESULTS Thirty-nine live surgery cases in the study group were case-matched with its thirty-nine counterparts as the control group. Operating time was longer (200 vs 165 min; p = 0.002) and estimated intraoperative blood loss was higher in the study group (100 vs 55 ml; p = 0.008). Patients in the study group stayed longer in the hospital (6 vs 5 days; p = 0.001). While conversion (n = 4 vs n = 1, p = 0.358) and intraoperative complications (n = 6 vs n = 2, p = 0.2) were more frequent in the study group, these outcomes did not reach statistical significance. Overall complications were higher in the study group (n = 22 vs n = 9, p = 0.003). One patient underwent a reoperation due to postoperative bleeding, and one mortality occurred in the live surgery group. CONCLUSIONS Live surgical demonstrations in minimally invasive colorectal surgery seem to be associated with increased risk of operative morbidity.We tested the hypothesis that left ventricular (LV) myocardial stiffness is altered in patients with transposition of great arteries (TGA) after arterial switch operation (ASO) and explored its associations with myocardial calibrated integrated backscatter (cIB) and LV myocardial deformation. Thirty-one patients and twenty-two age-matched controls were studied. this website LV myocardial stiffness was assessed by diastolic wall strain (DWS) and stiffness indices including (E/e)/LV end-diastolic dimension, (E/LV global longitudinal early diastolic strain rate)/LV end-diastolic volume, and (E/LV global circumferential early diastolic strain rate)/LV end-diastolic volume, where E and e are early diastolic transmitral and mitral annular velocities, respectively. LV myocardial cIB and longitudinal and circumferential myocardial deformation were determined by conventional and speckle tracking echocardiography. Patients had significantly lower DWS, higher stiffness indices, and greater myocardial cIB than controls (all p  less then  0.05). The LV longitudinal and circumferential systolic strain and systolic and diastolic strain rates were significantly lower in patients than controls (all p  less then  0.05). Greater average myocardial cIB was associated with lower DWS (r = - 0.44, p = 0.002). Worse DWS and LV stiffness indices were found to correlate with lower mitral annular systolic velocity, mitral annular late diastolic velocity, and LV longitudinal late diastolic strain rate (all p  less then  0.05). LV longitudinal and circumferential systolic strain and strain rate were also found to correlate with DWS (all p  less then  0.05). In conclusion, LV myocardial stiffening occurs in adolescents and young adults with TGA after ASO and is associated with impairment of ventricular systolic and diastolic myocardial deformation and myocardial fibrosis.Fontan-palliated patients are at risk for the development of Fontan-associated liver disease (FALD). In this study, we performed a detailed hemodynamic and hepatic assessment to analyze the incidence and spectrum of FALD and its association with patients' hemodynamics. From 2017 to 2019, 145 patients underwent a detailed, age-adjusted hepatic examination including laboratory analysis (FibroTest®, n = 101), liver ultrasound (n = 117) and transient elastography (FibroScan®, n = 61). The median patient age was 16.0 years [IQR 14.2], and the median duration of the Fontan circulation was 10.3 years [IQR 14.7]. Hemodynamic assessment was performed using echocardiography, cardiopulmonary exercise capacity testing and cardiac catheterization. Liver ultrasound revealed hepatic parenchymal changes in 83 patients (70.9%). Severe liver cirrhosis was detectable in 20 patients (17.1%). Median liver stiffness measured by FibroScan® was 27.7 kPa [IQR 14.5], and the median Fibrotest® score was 0.5 [IQR 0.3], corresponding to fibrosis stage ≥ 2.
