Venoarterial Extracorporeal Membrane Oxygenation and Implantable Cardioverter-Defibrillator Implantation in a Hemodynamically Unstable Infant with Ventricular Tachycardia from Multiple Cardiac Rhabdomyomas

Tuberous sclerosis complex (TSC) is a neurocutaneous disorder characterized by benign tissue hamartomas in multiple organ systems, including cardiac rhabdomyomas. Though prevalent in TSC, cardiac tumors are rare in children, occurring in about 0.03%–0.17%. Rhabdomyomas are the most common, accounting for 45%. When present, they are multiple and in the ventricular myocardium. Frequently, they regress and surveillance is all that is required until spontaneous regression. Intervention is necessary when life-threatening obstruction or hemodynamically significant refractory arrhythmias occur. This case highlights the course of a 6-month-old infant with TSC and cardiac rhabdomyomas who presented in refractory ventricular tachycardia (VT) with decompensation and cardiac arrest necessitating venoarterial extracorporeal membrane oxygenation (VA-ECMO), complex antiarrhythmic therapy, and ultimately implantable cardioverter-defibrillator (ICD) implantation

Use of Cellulosic Materials as Dye Adsorbents — A Prospective Study

Cellulose is the most abundant biopolymer of nature, and it is widely used in the synthesis of new materials as well as in the adsorption of dye. This study reports a literature review (articles) and technology review (patents) about publications and product invention, which contain information on the use of cellulose on the adsorption of dyes in the period 2004–2014. For this work, research database and keywords were used to find articles and patents related to the subject under review. Specific words were used to find articles and patents related to the subject under review. After a demanding research, 1 patent and 23 articles that contain the words “cellulose,” “dye,” and “adsorption or sorption” in their titles were assessed, and annual evolution studies were performed for publications and countries that publish more

“I Ran to Make a Point”: Predicting and Preventing Youth Runaway from Foster Care

Youth who run away from foster care experience danger to health and safety and increased risk of adverse child welfare outcomes. By applying a concurrent mixed-methods approach, this study aimed to develop a deeper understanding of runaway risk that used a person-centered lens and amplified youth voices. Collectively, this approach can inform service innovations to support youth placed in out-of-home care. Working with a foster care agency in Kansas, data sources comprised administrative data for youth ages 12 + in care, and interview data with 20 youth, 12 + in care. Quantitative analyses involved latent class analysis followed by multinomial logistic regression to investigate whether the population of youth in care was comprised of subpopulations with differential runaway risk and whether subpopulations would predict runaway behaviors. Qualitative analyses applied modified analytic inductive thematic analysis to explore critical life experiences that may act as risk or protective factors of running away from care. Results revealed four sub-populations which were characterized by their previous family and system experiences. Additionally, class membership, gender, number of siblings, and age were statistically significant predictors of runway behaviors. Youth interviews revealed five key themes on life experiences that mitigate or exacerbate youths’ runaway behaviors. Recommendations resulting from this study were provided in three key areas: (1) improving family visitation and maintaining youth connections with self-identified family and non-relative kin; (2) supporting service approaches for youth that honor and amplify their voices, choices, and family connections; and (3) improving placement quality and individualization of services

Chemical Functionalization of Cellulosic Materials — Main Reactions and Applications in the Contaminants Removal of Aqueous Medium

The cellulose is the most abundant biopolymer in the world and presents a higher chemical variability for presence of several hydroxyl groups. These hydroxyl groups allow surface modification of biomaterials, with insertion of several chemical groups which change cellulose characteristics. This natural biopolymer and its derivatives have been used a lot as adsorbent, from several contaminants of aqueous medium due to biocompatibility, chemical degradability, and variability. Therefore, this chapter has the objective to review the literature about several cellulose surfaces or cellulosic material (incorporation of carboxymethyl, phosphorus, carboxyl, amines, and sulfur), presenting the main characteristics of reactions and showing its adsorption in application of aqueous medium (metals, dyes, and drugs), locating the main interactions between biomaterial/contaminant
