Notes

Debridement with regard to venous lower leg ulcers.
Left atrial (LA) enlargement is present in the majority of adult heart transplant (HT) recipients. see more We used speckle-tracking echocardiography to investigate whether LA phasic function in HT patients is altered and explored its relationship to HT-related clinical variables. This study evaluated LA function in 112 clinically well HT patients and 40 healthy controls. Clinical data included recipient age at HT, donor age, ischemia time, left ventricular function, and biochemical indicators. Atrial deformation and volume indices were measured with two-dimensional and three-dimensional speckle-tracking echocardiography, respectively. Components of phasic atrial function were calculated and correlations to clinical variables were explored. Compared with controls, HT patients had worse LA reservoir, conduit, and pump function. LA reservoir function of the bicaval group was better than the biatrial group, but differences did not persist after adjustment for potential confounders. Among patients with HT, those with lower LAS-peak had an older recipient age, larger LA volume, as well as worse left ventricular systolic function than those patients with higher LAS-peak. However, E/e', biochemical indicators and donor-related information were similar across the quartiles of LA function. In HT cohort, we observed impairment in all phases of LA function, and LA reservoir function was decreased independent of surgical technique. LAS-peak was associated with worse left ventricular systolic function, which suggested that LA function may play an important role in HT patients.Paracardial cystic lesions (PCLs) are rare, benign lesions and may occur in any part surrounding the heart. It covers a variety of pathological types, including pericardial cysts, thymic cysts, bronchogenic cysts and so on. The aim of this study was to summarize the diagnostic value of echocardiography in different pathological types of the PCLs. Echocardiographic features of 43 consecutive PCL patients treated at the Union Hospital from January 2002 to December 2017 were compared and analyzed with their surgical and pathological findings retrospectively. The PCLs included 19 pericardial cysts, 12 thymic cysts, 7 bronchogenic cysts, 3 cystic teratomas, 1 enteric cyst and 1 lymphangioma. Among them, 29 cases (67.4%) were accurately diagnosed by echocardiography and 14 cases (32.6%) were missed the diagnosis. All diagnosed cysts were showed as thin-walled, monolocular, echo-free structures without blood flow signals in echocardiographic images. 4 patients had compression of the heart and great vessels caused by cysts. In addition, 4 intracardiac lesions were diagnosed by echocardiography and the results were further confirmed in surgery. Echocardiography is of great value in the diagnosis of paracardiac cystic lesions as well as combined intracardiac lesions. Differential diagnosis could be mainly made based on the location of the lesions.Little has been reported on the left ventricular myocardial distension (bounce) and its utility to assess cardiac function. The purpose of this study is to determine whether myocardial bounce at end diastole is reproducibly visualized by blinded observers and to determine whether it corresponds to systolic and diastolic function. 144 Consecutive cardiac MR exams between September and December 2017 were selected for analysis. The bounce was graded by two blinded observers, and the change in LV diameter pre and post bounce was measured. The bounce was defined as the rapid change in LV volume that occurs at the end of diastole during atrial contraction just prior to systolic ejection. Inter-reader agreement was summarized using Cohen's kappa. Spearman's rank correlation coefficient was used to evaluate associations between bounce grade and cardiac physiology parameters. Overall agreement was good with unweighted kappa = 0.69 (95% CI 0.60-0.79). Bounce grade was significantly correlated with the average change iniac MR exams was predictive of normal diastolic and systolic cardiac function. Lack of myocardial bounce was highly associated with both systolic and diastolic dysfunction. The subpopulation of patients with loss of myocardial bounce and normal ejection fraction appear to represent patients with early diastolic dysfunction. Further studies with more diastolic dysfunction MRs are needed to examine this relationship. This study suggests changes to the myocardial bounce seen on cardiac MR may be a simple useful tool for detecting cardiac dysfunction. This study is not to replace, but rather aid the clinical diagnosis and management of both diastolic and systolic dysfunction.Narrative form is crucial to the understanding of science in popular culture. This is particularly true with subjects such as radiation, in which the technical details at hand are often remote from everyday experience-as well as contested or uncertain among experts. This article examines the narrative choices made by three popular texts that publicized radiation risks to the public during the Cold War John Hersey's Hiroshima, David Bradley's No Place to Hide, and Ralph Lapp's The Voyage of the Lucky Dragon. It contends that each author borrowed from well-established literary genres and that this borrowing was crucial to coherence and effective messaging of the argument. At the same time, placing the arguments in such a familiar form served to blunt some of the radical potential in those same messages.Purslane is a widespread wild vegetable with both medicinal and edible properties. It is highly appreciated for its high nutritional value and is also considered as a high-quality feed resource for livestock and poultry. In this study, Sanhuang broilers were used to investigate the effect of feeding purslane diets on the growth performance in broilers and their gut microbiota. A total of 48 birds with good growth and uniform weight were selected and randomly allocated to four treatment groups A (control), B, C and D. Dietary treatments were fed with basal diet without purslane and diets containing 1%, 2% and 3% purslane. The 16S rDNA was amplified by PCR and sequenced using the Illumina HiSeq platform to analyze the composition and diversity of gut microbiota in the four sets of samples. The results showed that dietary inclusion of 2% and 3% purslane could significantly improve the growth performance and reduce the feed conversion ratio. Microbial diversity analysis indicated that the composition of gut microbiota of Sanhuang broilers mainly included Gallibacterium, Bacteroides and Escherichia-Shigella, etc.
