AIM To explore the feasibility and value of transthoracic echocardiography (TTE) postprocessing subtraction technique in the detection of a stent in the coronary artery. METHOD Transthoracic echocardiography was used to examine 46 coronary artery stents in 30 patients by two-dimensional ultrasound postprocessing subtraction technique. The shape of each stent and its flow patency were observed. The patency was assessed according to blood flow and mosaic flow in the stent. Then, the results were compared with those of percutaneous coronary intervention (PCI) records and coronary angiography (CAG). RESULTS Transthoracic echocardiography detected 36 stents among 46 stents (two in the LMCA, 23 in the LAD, seven in the RCA, and two in the LCX); the detection rate was 78.3%. The average length of the stents was 21.8 ± 4.1 mm, and the average diameter was 2.4 ± 0.5 mm; both are shorter than those from PCI records (P  less then  .001). Of the 36 stents, blood flow could be observed in 27. Compared with the results of CAG, TTE had 75% feasibility and 92.6% accuracy in detecting flow patency in the stents. CONCLUSION Transthoracic echocardiography postprocessing subtraction technique could be a noninvasive method for detecting a coronary artery stent and, although the measurements of stent length and diameter were shorter than those of PCI records, an accurate detection of flow patency in the stents was achieved. © 2020 Wiley Periodicals, Inc.A large number of studies in recent years indicated the involvement of peripheral circadian clock in varied pathologies. However, evidence regarding how peripheral clocks regulate bone metabolism is still very limited. The present study aimed to investigate the direct role of Bmal1 (the key activator of peripheral circadian clock system) in vivo during bone developmental and remodeling stages using inducible osteoblast-specific Bmal1 knockout mice. Unexpectedly, the removal of Bmal1 in osteoblasts caused multiple abnormalities of bone metabolism, including a progressive increase in trabecular bone mass in as early as 8 weeks, manifested by an 82.3% increase in bone mineral density and 2.8-fold increase in bone volume per tissue volume. As mice age, an increase in trabecular bone mass persists while cortical bone mass decreases by about 33.7%, concomitant with kyphoscoliosis and malformed intervertebral disk. The increased trabecular bone mass is attributed to increased osteoblast number and osteoblast activity coupled with decreased osteoclastogenesis. Remarkably, the ablation of Bmal1 in osteoblasts promoted the expression level of Bmp2 and phosphorylation of SMAD1, whereas the attenuation of BMP2/SMAD1 signaling partially alleviated the effects of Bmal1 deficiency on osteoblast differentiation and activity. The results revealed that Bmal1 was a transcriptional silencer of Bmp2 by targeting the Bmp2 promoter. The peripheral clock gene Bmal1 in osteoblasts was crucial to coordinate differential effects on trabecular and cortical bones through regulating BMP2/SMAD1 during bone development, thus providing novel insights into a key role of osteoblast Bmal1 in homeostasis and integrity of adult bones.

METHODS The study population included all very preterm singletons born because of suspected FGR or maternal hypertensive disorders included in EPIPAGE-2, a prospective, nationwide, population-based cohort of preterm births in France in 2011. We analyzed the association of ARED in the umbilical artery with severe or moderate neuromotor or sensory disabilities, and with an Age and Stages Questionnaire (ASQ) score below the threshold at age 2. ASQ is used to identify children at risk of developmental delay needing reinforced follow-up and further evaluation. We performed univariate and two-level multivariable logistic regression analyses. find more RESULTS The analysis included 484 children followed up at 2 years of age for whom prenatal umbilical Doppler ultrasound was available. Among them, 8 (1.5%) had severe or moderate neuromotor or sensory disabilities, and 156 (43.9%) had an ASQ score below the threshold. Compared to normal or reduced end diastolic flow in the umbilical artery (n=305), ARED (n=179) was associated with either severe or moderate neuromotor or sensory disabilities (adjusted OR 11.3, 95% CI 1.4-93.4) but not with an ASQ score below the threshold (adjusted aOR 1.2, 95% CI 0.8-1.9). CONCLUSION Among children born before 32 weeks of gestation because of suspected fetal growth restriction or hypertensive disorder who survived until age 2, prenatal ARED in the umbilical artery was associated with more frequent moderate or severe neuromotor or sensory disabilities.

All aspects of life have changed dramatically for now. The group most susceptible to COVID-19 are older adults and those with chronic underlying chronic medical disorders. The population residing in long-term care facilities generally are those who are both old and suffering from multiple comorbidities. In this article we provide information, insights, and recommended approaches to COVID-19 in the long-term facility setting.
