AV canal defects (AVCD) are caused by maldevelopment of the endocardial cushions and typically include a primum atrial septal defect (ASD), an inlet ventricular septal defect (VSD), and a common atrioventricular valve. The variations in deformities provide the basis for the many terms used in the anatomical classifications partial, transitional, intermediate, and complete common AVCD (balanced or unbalanced). The balanced complete common AVCDs are classified as Rastelli A, B, C depending on the anomaly of the anterior bridging leaflet division and attachments. Unbalanced complete AVCDs occur when the common AV valve leads primarily into the RV or LV. Echocardiographic apical, subcostal, and parasternal views are the best views to image AV canal defects. These views can help determine the type of repair required for the various AV canal defects.Transposition of the great arteries (TGA) is a common cardiac malformation in which the great arteries are discordant relative to the ventricles. The two common forms of transposition include D-TGA, which presents with cyanosis early in life, and L-TGA, which on the other hand, may permit survival to adulthood without being diagnosed in childhood. There are remarkable differences between these two forms of TGA in the clinical presentation, echocardiographic findings, and long-term outcomes. Multimodality imaging in patients with TGA usually provides diagnostic and hemodynamic assessment for routine follow-up and preoperative planning prior to surgical or transcatheter intervention. In this review, we present a summary of the fundamental echocardiographic aspects of these two forms of TGA with emphasis in the adult congenital heart disease population.Ventricular septal defects (VSDs) are the most common forms of acyanotic congenital heart disease accounting for 37% of congenital heart disease in children. A VSD is defined by parts of the ventricular septum involved. There are four major types of VSDs perimembranous, muscular, outlet, and inlet VSDs. Echocardiography is the most important clinical tool to help diagnose and characterize a VSD. Although most VSDs are clinically nonsignificant or close on their own, echocardiography with Doppler and color flow mapping can be used to provide accurate anatomic and hemodynamic evaluation of VSDs in order to determine if surgical or transcatheter-based intervention is needed. Hence, understanding how to use echocardiography to characterize VSDs is of crucial importance when caring for patients with adult congenital heart disease.

The spectrum of human adenovirus (HAdV)-related disease is broad, and the virus acts on many organs and systems in hematopoietic stem cell transplantation (HSCT) recipients. We aimed to evaluate the effect of HAdV-DNA positivity with clinical and laboratory findings 4months after HSCT.

We retrospectively investigated HAdV-DNA in 153 HSCT recipients (≤18years) by quantitative real-time polymerase chain reaction (RealStar; Altona Diagnostics). The results of samples from January 2014 to December 2017 are included. HAdV-DNA was positive for at least one sample type in 50 (32.67%) patients. HAdV-DNA positivity rate was 8.92% (N 145/1625), 40.25% (N 64/159), and 25% (N 2/8) for plasma, stool, and urine samples, respectively. HAdV-DNA was positive in the plasma of 38 (24.83%) patients at a median 16 (range 1-58days) days after HSCT. The mortality rate was 23.68% and 6.95% in plasma HAdV-positive and HAdV-negative patients (p=.014). Moreover, HAdV-DNA positivity had an impact on overall survival for allogeneic-HSCT (p=.013), with the cumulative effect including graft-versus-host disease state in multivariate analysis (p=.014).

Plasma HAdV-DNA positivity is a potential influencer that decreases survival in the early post-transplant period. Due to the high mortality rates, close monitoring is required of HAdV infections after HSCT with sensitive methods, especially at the early stage.

Between 2014 and 2019, we prospectively evaluated adult hypospadias and adult circumcision patients. A total of 28 patients were included Group 1 (18 patients) primary distal hypospadias and Group 2 (10 patients-control group) healthy individuals who had a previous circumcision request for social/religious reasons. The prepuce of healthy individuals that were excised after the circumcision and the excised parts excluded from the prepuce that was used in reconstruction during the repair of hypospadias, were shaped and stored to be able to perform a study by the pathology clinic. Histopathological findings on adult distal hypospadias cases showed that the microvascular density and inflammation in the prepuce with hypospadias were found to be increased compared to the healthy prepuce and the density of androgen and oestrogen receptors was similar in both groups. Unlike childhood studies, in this study with adults, the progesterone receptor was detected in both groups and found to be significantly lower in the hypospadias group.The effects of social isolation on an individual’s behavior is an important field of research, especially as public health officials encourage social distancing to prevent the spread of pandemic disease. In this study we evaluate the effects of social isolation on physical activity in mice. NU7441 Utilizing a pixel-based tracking system, we continuously monitored the movement of isolated mice compared with paired cage mates in the home cage environment. We demonstrate that mice that are socially isolated dramatically decrease their movement when separated from their cage mate, and especially in the dark cycle, when mice are normally most active. When isolated mice are re-paired with their original cage mate, this effect is reversed, and mice return to their prior levels of activity. These findings suggest a close link between social isolation and physical activity, and are of particular interest in the wake of coronavirus disease 2019, when many are forced into isolation. Social isolation may affect an individual’s overall activity levels in humans too, which may have unintended effects on health that deserve further consideration.
