Vertebral artery (VA) aneurysms in the paediatric population are a rare but a serious condition. However, the epidemiology of paediatric VA aneurysms is poorly understood and there is little consensus on what constitutes the appropriate treatment. Although multiple treatment options are available, including surgery, endovascular approaches, coil embolization and parent artery occlusion, there is limited clinical evidence regarding which approach is most optimal. This review outlines the current literature and evidence outlining the epidemiology, presentation, pathogenesis and treatment of paediatric VA aneurysms...

BACKGROUND: The 2014 implementation of the Veterans Choice Program increased opportunities for Veterans to receive care in the community. Although surgical care is a Veterans Health Administration (VA) priority, little is known about the types of surgeries provided in the VA versus those referred to community care (CC), and whether Veterans are increasing their use of surgical care through CC with these additional opportunities. OBJECTIVES: To examine national trends across VA facilities in the frequencies and types of surgeries provided in the VA and through CC, and explore the association between facilities' purchase of care with rurality and surgical complexity designation...

Short-term ventricular assist devices (ST-VAD) have been effective in treating patients with refractory cardiogenic shock. Membrane oxygenators (MO) can be added to the circuit for concomitant profound refractory hypoxia. This study reports outcomes of combined therapy in this portion of patients. This is a retrospective review of 166 patients who received an ST-biventricular assist device (BiVAD) or right ventricular assist device (RVAD) for cardiogenic shock between November 2007 and November 2014. An MO was added to the RVAD for profound hypoxia refractory to maximized ventilation...

A cavopulmonary assist device (CPAD) has been developed for failing Fontan support. This CPAD pumps blood from superior/inferior vena cavae to pulmonary artery. In this study, we compared failing Fontan support with CPAD versus VA ECMO in silico. A numerical lumped-parameter circulatory system model was used to simulate Fontan circulation. Failing Fontan was simulated by increased pulmonary resistance. Central venous pressure (CVP), mean pulmonary arterial pressure (mPAP), left atrial pressure (LAP), and univentricular outflow (CO) were simulated and compared to published clinical data...

The area of uveitis is related to numerous pathological entities. One of the main causes of decreased visual acuity in these patients is macular edema. One aspect of the treatment includes cortosteroids used peri- and intra-ocularly. MATERIALS AND METHODS: The goal of our work was to estimate the criteria of efficacy (on improvement in visual acuity and macular edema, as well as time to recurrence) and safety (on intraocular pressure and cataract) of these various routes of administration of corticosteroid after a single injection...

BACKGROUND: Prior studies have shown that late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) and fluorodeoxyglucose (FDG) positron emission tomography (PET) confer incremental risk assessment in patients with cardiac sarcoidosis (CS). However, the incremental prognostic value of the combined use of LGE and FDG compared to either test alone has not been investigated, and this is the aim of the present study. METHODS: Retrospective observational study of 56 symptomatic patients with high clinical suspicion for CS who underwent LGE-CMR and FDG-PET and were followed for the occurrence of death and/or malignant ventricular arrhythmias (VA)...

The critical points and the corresponding singularities in the density of states of crystals were first classified by Van Hove with respect to their dimensionality and energy-momentum dispersions. Here, different from saddle-point Van Hove singularities, the occurrence of a continuum of critical points, which give rise to strong singularities in two-dimensional elemental hexagonal lattices, is shown using a minimal tight-binding formalism. The model predicts quartic energy-momentum dispersions in spite of quadratic or linear ones, which is also the origin of the strong singularity...

BACKGROUND: Many medical schools have adopted the longitudinal integrated clerkship (LIC) model in response to calls for increased continuity in clinical learning environments. However, because of implementation challenges, such programs are not feasible at some institutions or are limited to a small number of students. OBJECTIVE: In January 2014, Columbia University College of Physicians and Surgeons (P&S) recognized the need to explore different LIC formats and began offering four, 12-week amalgamative clerkships (AC)...

Infantile fibrosarcoma is a non-rhabdomyosarcoma soft-tissue sarcoma that occurs in infancy and which has a relatively good prognosis. A vincristine and dactinomycin (VA) regimen has been shown to be effective, although the duration of chemotherapy has not been well defined. We describe the case of a 4-month-old boy with a mass at the left dorsum of the foot who was diagnosed with infantile fibrosarcoma after resection of the tumor, the margin of which was macroscopically positive. VA treatment was carried out with careful monitoring of response and adverse effects...

Significant changes in national health policy, like the Veterans Choice Act, have created growing opportunities for veterans to receive care outside of the Veterans Administration (VA), yet little is known about the attitudes and practices in PTSD care of community providers, particularly their use of evidence-based psychotherapies (EBPs). The authors assessed psychotherapy practices of community providers serving veterans with PTSD in Texas. They surveyed Texas mental health providers regarding their patient population, practice setting, and posttraumatic stress disorder (PTSD)-related screening, assessment, and treatment practices...

Background: Vitamin A (VA; retinol) supplementation is used to reduce child mortality in countries with high rates of malnutrition. Existing research suggests that neonates (<1 mo old) may have a limited capacity to store VA in organs other than the liver; however, knowledge about VA distribution and kinetics in individual, nonhepatic organs is limited.Objective: We examined retinol uptake and turnover in nonhepatic organs, including skin, brain, and adipose tissue, in neonatal rats without and after VA supplementation...

The association between inflammation and vitamin A (VA) metabolism and status assessment has been documented in multiple studies with animals and humans. The relation between inflammation and carotenoid status is less clear. Nonetheless, it is well known that carotenoids are associated with certain health benefits. Understanding these relations is key to improving health outcomes and mortality risk in infants and young children. Hyporetinolemia, i.e., low serum retinol concentrations, occurs during inflammation, and this can lead to the misdiagnosis of VA deficiency...
