Contemporary Trends and Comparison of Racial Differences in Hospitalizations of Adults With Congenital Heart Disease.

As advancements in care improve longevity in patients with congenital heart disease (CHD), it is crucial to further characterize this rapidly growing adult population. It is also essential that equitable care is offered across demographic groups. Hospitalizations for adults with CHD in the National Inpatient Sample were identified to describe trends in overall and cause-specific rates of admission per 1,000 adults with CHD from 2000 to 2018.

Beyond the Syndrome: Extensive Congenital Abnormalities in an Infant With Trisomy 21.

Herein we discuss the clinical course and subsequent autopsy of a female infant with trisomy 21 with balanced Rastelli Type "C" complete atrioventricular septal defect (AVSD), tetralogy of Fallot and right aortic arch with mirror image branching pattern who underwent a palliative right modified Blalock-Taussig-Thomas shunt (mBTTS) for hypoxemia from progressive right ventricular outflow tract obstruction. The baby was found to have multiple concomitant pathologic findings not typically seen with this constellation of cardiac anatomy. Autopsy revealed significant abdominal adhesions with near-complete stenosis of the transverse colon.

A High-Fidelity Percutaneous Model Used to Demonstrate ECMO Cannulation.

Medical simulation provides a realistic environment for practitioners to experience a planned clinical event in a controlled educational setting. We established a simulation model composed of synthetic ballistic gelatin that provided an inexpensive high-fidelity model for our extracorporeal membrane oxygenation (ECMO) team members to develop, master, and maintain clinical skills necessary for percutaneous cervical or femoral cannulation. The simulation component includes a cervical torso or femoral percutaneous synthetic gelatin model that is attached to either a static fluid model or to the high-fidelity perfusion simulator.

Use of VA ECMO and percutaneous palliation of ductal dependent coarctation in a neonate with trisomy 21 and COVID-19 pneumonia.

We present a case of a neonate with trisomy 21, ductal-dependent aortic coarctation, and severe respiratory failure secondary to coronavirus disease 2019 (COVID-19) pneumonia. The neonate was managed with venoarterial extracorporeal membrane oxygenation (VA ECMO), palliative stenting of the coarctation, and a vascular plug occlusion of a large patent ductus arteriosus. The patient was successfully weaned off extracorporeal membrane oxygenation (ECMO).

Median Sternotomy for Innominate Artery Compression Syndrome and Distal Tracheal Stenosis.

We present a case of a premature infant who had an initial diagnosis of an innominate artery compression syndrome. This was approached by a median sternotomy for an aortopexy. However, the patient was found to have a distal tracheal stenosis due to a tracheal cartilage deficiency and was treated by a tracheal resection and primary anastamosis.

Gender Disparity in Breast Cancer: A Veteran Population-Based Comparison.

Background: Male breast cancer (MBC) comprises <1% of all cancers and continues to rise. Because of rarity, there is paucity in the literature; therefore, management of MBC is generalized from female breast cancer (FBC).

Methods: Data from 152 VA Medical Centers were used to analyze the database of Veteran patient with breast cancer diagnosed between 1998 and 2016 using biostatistical software (SAS 9.

Outcome of Bridge to Lung Transplantation With Extracorporeal Membrane Oxygenation in Pediatric Patients 12 Years and Older.

Background: There is a reluctance to using extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplantation in the pediatric population. Pediatric patients between ages 12 and 18 years are eligible for acuity-based lung transplantation using the Lung Allocation Score and may be suitable for adult allografts, increasing the donor pool and thus leading to a successful bridge to lung transplantation.

Methods: The United Network for Organ Sharing dataset was queried for primary lung transplantation in pediatric patients (12-18 years) from 2005 to 2016.

Structural and functional significance of scrotal ligament: a comparative histological study.

Gubernaculum testes is the most important parameter in testicular migration. At the end of migration, it is described as scrotal ligament, which has implications in testicular torsion. The present study aims to examine the structure of scrotal ligament and compare it with gubernaculum.

Important role of annexin A2 (ANXA2) in new blood vessel development in vivo and human triple negative breast cancer (TNBC) growth.

Development of new blood vessels in the tumor microenvironment is an essential component of tumor progression during which newly formed blood vessels nourish tumor cells and play a critical role in rapid tumor growth, invasion and metastasis. Nevertheless, how tumor cells develop new blood vessels in the tumor microenvironment (TME) have been enigmatic. Previously, we have shown specific overexpression of ANX A2 in TNBC cells regulates plasmin generation and suspected a role in neoangiogenesis.

Orthotopic Heart Transplantation in a Patient With Gitelman Syndrome and Dilated Cardiomyopathy.

Gitelman syndrome (GS) is a rare hereditary tubulopathy affecting the distal tubule leading to significant electrolyte disturbances. Although generally a benign condition, rare associations with arrhythmias and sudden cardiac death have been reported. A paucity of literature exists associating GS with cardiomyopathy.

Impact of Circuit Size on Coagulation and Hemolysis Complications in Pediatric Extracorporeal Membrane Oxygenation.

Extracorporeal membrane oxygenation (ECMO) circuit volume, patient size, and blood flow may influence coagulation and hemolysis complications. We performed a single-center retrospective analysis of ECMO patients over a 6.5 year period.

Highly atom-economical, catalyst-free, and solvent-free phosphorylation of chalcogenides.
