10 cycles/mm. The DAS-Net method outperformed zero-filling (root Mean Square error = 5.8 ± 1.5 vs 13.5 ± 1.5, DAS-Net vs zero-filling, P < .01; and structural similarity index = 0.83 ± 0.04 vs 0.66 ± 0.03, DAS-Net vs zero-filling, P < .01). Strain data for non-phase-cycled DENSE images with DAS-Net showed close agreement with strain from phase-cycled DENSE.

The DAS-Net method provides an effective alternative approach for suppression of the artifact-generating T

-relaxation echo in DENSE MRI, enabling a 42% reduction in scan time compared to DENSE with phase-cycling.

Although the influence of copper ([Cu]) on chronic hepatitis (CH) has been widely studied in dogs, little information is available about the accumulation of other metals.

We assessed the concentration of lead ([Pb]) in the livers of dogs with CH with or without abnormal hepatic [Cu] to establish if any association existed between [Pb] and either hematologic or biochemical variables, fibrosis, necrosis and inflammation of the liver on histology.

Thirty-four dogs with CH that had hepatic [Cu] and [Pb] determined.

Retrospective review of medical records of dogs with CH and hepatic [Cu] and [Pb]. Chronic hepatitis was defined using current American College of Veterinary Internal Medicine consensus statement guidelines. Hepatic [Cu] and [Pb] were determined using square wave anodic stripping voltammetry. Dogs were divided into 2 groups based on [Cu] <400 ppm (LoCu) and ≥400 ppm (HiCu).

The median [Cu] and [Pb] were 357 ppm (range, 100-7743 ppm) and 58.7 (range, 6.89-224.4ppm), respectively. Nineteen dogs had LoCu and 15 dogs had HiCu. Median [Pb] was significantly higher in HiCu compared to LoCu dogs (P < .001). Hepatic [Pb] and [Cu] were significantly correlated (rho=0.7; P < .001). Dogs with microcytosis had higher [Pb] than did dogs with normal red cell volume (P=.02). Hepatic [Pb] was not correlated with either necroinflammatory or fibrosis scores.

Although additional studies are needed to better understand the clinical role of hepatic [Pb], dogs with abnormal hepatic [Cu] may also have higher hepatic [Pb]. In addition, in dogs with high hepatic [Pb], microcytosis may be present.

The device offers superior technical features and experienced interventionists having been using it in risky and complex anatomies. Herein, we report the first use of the MFO device to close a congenital Gerbode-type perimembranous ventricular septal defect in an 18-year-old girl. The device was retrogradely implanted into proper position under ultrasound and fluoroscopic guidance. Immediate and 12-month-follow-up confirmed successful outcomes with complete shunt closure and resolution of tricuspid regurgitation.Traumatic experiences have been differentiated as interpersonal (i.e., the direct result of actions by other people) or noninterpersonal (i.e., other life-threatening events, such as severe accidents). Interpersonal trauma exposure generally has been shown to be associated with more severe posttraumatic stress disorder (PTSD) symptoms than noninterpersonal trauma exposure. Interpersonal problems also tend to be associated with trauma exposure and PTSD symptoms, but it is unclear whether a mediating association exists between trauma type, interpersonal problems, and PTSD symptoms. A clinical sample of 4,275 adolescents (age range 12-18 years) from the National Child Traumatic Stress Network Core Data Set were classified as having experienced interpersonal trauma, noninterpersonal trauma, or both. Interpersonal problems were operationalized by social problem behaviors (e.g., immature and dependent behaviors) and aggressive behaviors on the Child Behavior Checklist. The results of path analyses showed that cumulative interpersonal trauma exposure was both directly and indirectly associated with PTSD symptoms via social problem behaviors but not aggressive behaviors, total effect β = .20, 95% CI [.17, .23]. In a second model, path analyses showed that cumulative interpersonal trauma exposure was associated directly and indirectly via PTSD symptoms with social problem behaviors, total effect β = .15, 95% CI [.11, .18], and aggressive behaviors, total effect β = .13, 95% CI [.09, .17]. These findings suggest that during adolescence, interpersonal problems play an important role in the association between interpersonal trauma exposure and PTSD symptoms.Nasogastric/nasoenteric (NG/NE) feeding tube placements are associated with adverse events and, without proper training, can lead to devastating and significant patient harm related to misplacement. Safe feeding tube placement practices and verification are critical. There are many procedures and techniques for placement and verification; this paper provides an overview and update of techniques to guide practitioners in making clinical decisions. Regardless of placement technique and verification practices employed, it is essential that training and competency are maintained and documented for all clinicians placing NG/NE feeding tubes. This paper has been approved by the American Society for Parenteral and Enteral Nutrition (ASPEN) Board of Directors.

Coronavirus disease 2019 (COVID-19) has caused an increase in patients requiring enteral feeding access while undergoing proning for severe acute respiratory distress syndrome (ARDS). We investigated the safety and feasibility of fluoroscopy-guided nasojejunal (NJ) feeding tube placement in the prone position.

This is a retrospective cohort study of all patients who underwent fluoroscopic placement of NJ feeding tubes at a single institution between March 2020 and December 2020. Primary end points were success rate and number of attempts. Chi-squared and Fischer exact tests were used to compare prone and supine groups.

A total of 210 patients were included in the study 53 patients received NJ feeding tubes while prone and 157 while supine. All but one patient in the prone group had ARDS secondary to COVID-19, whereas 47 (30.3%) had COVID-19 in the supine group. The rate of successful placement was 94.3% in the prone group and 100% in the supine group. Mean number of attempts was 1.1 (SD, ±0.4) in the prone and 1.0 (SD, ±0.1) in the supine group (P = .14). Prone patients had a longer median fluoroscopy time (69 s, interquartile range [IQR] = 92; vs 48 s, IQR = 43; P < .001) and received a higher radiation dose during the procedure (47 mGy, IQR = 50; vs 25 mGy, IQR = 33; P = .004). No procedural complications were reported.

Fluoroscopy-guided NJ feeding tube placement in prone patients is feasible and safe. selleck chemicals llc Patient positioning should not delay obtaining postpyloric feeding access.

Alterations of the gut microbiome in Parkinson disease (PD) have been repeatedly demonstrated. However, little is known about whether such alterations precede disease onset and how they relate to risk and prodromal markers of PD. We investigated associations of these features with gut microbiome composition.

Established risk and prodromal markers of PD as well as factors related to diet/lifestyle, bowel function, and medication were studied in relation to bacterial α-/β-diversity, enterotypes, and differential abundance in stool samples of 666 elderly TREND (Tübingen Evaluation of Risk Factors for Early Detection of Neurodegeneration) study participants.

Among risk and prodromal markers, physical inactivity, occupational solvent exposure, and constipation showed associations with α-diversity. Physical inactivity, sex, constipation, possible rapid eye movement sleep behavior disorder (RBD), and smoking were associated with β-diversity. Subthreshold parkinsonism and physical inactivity showed an interactiomics data in incident PD cases. ANN NEUROL 2021.

Several risk and prodromal markers of PD are associated with gut microbiome composition. However, the impact of the gut microbiome on PD risk and potential microbiome-dependent subtypes in the prodrome of PD need further investigation based on prospective clinical and (multi)omics data in incident PD cases.

Gap junctions consisting of connexins (Cx) are fundamental in controlling cell proliferation, differentiation, and cell death. Cx43 is the most broadly expressed Cx in humans and is attributed an important role in skin tumor development. Its role in cutaneous vascular neoplasms is yet unknown.

Fifteen cases each of cutaneous angiosarcoma (cAS), Kaposi sarcoma (KS), and cherry hemangioma (CH) were assessed by immunohistochemistry for expression of Cx43. Expression pattern, intensity, and percentage of positively stained cells were analyzed. Solid basal cell carcinomas served as positive and healthy skin as negative controls.

Most cases of cAS presented with a strong Cx43 staining of almost all tumor cells, whereas endothelia of KS showed medium expression and CH showed mostly weak expression. In comparison with KS or cAS, the staining intensity of CH was significantly lower (P ≤ 0.001). All tissue sections of both cAS and KS were characterized by a mostly diffuse, cytoplasmic staining pattern of the vascular endothelia. None of those showed nuclear staining.

The high-to-intermediate expression of Cx43 observed in all cases of cAS and KS suggests that this Cx may play a role in the development of malignant vascular neoplasms and serve as a helpful diagnostic marker.

The endo-lysosomal system (ELS) comprises a set of membranous organelles responsible for transporting intracellular and extracellular components within cells. Defects in lysosomal proteins usually affect a large variety of processes and underlie many diseases, most of them with a strong neuronal impact. Mutations in the endoplasmic reticulum-resident CLN8 protein cause CLN8 disease. This condition is one of the 14 known neuronal ceroid lipofuscinoses (NCLs), a group of inherited diseases characterised by accumulation of lipofuscin-like pigments within lysosomes. Besides mediating the transport of soluble lysosomal proteins, recent research suggested a role for CLN8 in the transport of vesicles and lipids, and autophagy. However, the consequences of CLN8 deficiency on ELS structure and activity, as well as the potential impact on neuronal development, remain poorly characterised. Therefore, we performed CLN8 knockdown in neuronal and non-neuronal cell models to analyse structural, dynamic and functional changes in the ELS and to assess the impact of CLN8 deficiency on axodendritic development.
