RESUMEN
Genicular artery embolization (GAE) is a novel treatment for knee osteoarthritis (OA) with increasing interest and utilization worldwide. The genicular arteries are selectively embolized using microspheres with subsequent cessation of abnormal synovial hyperemia, a process believed to arrest the inflammatory changes and pain associated with OA. Current data indicate that GAE offers sustained, 6-month improvement in Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) and visual analog scale scores in 80 to 85% of patients with mild to moderate OA. As GAE gains traction, future studies are needed to establish its safety and efficacy relative to placebo and other standard-of-care therapies while also characterizing populations for which it is most effective.
RESUMEN
Endovascular arteriovenous fistula (endoAVF) creation offers a minimally invasive method for the formation of arteriovenous shunts utilized for hemodialysis. Currently, there exist two similar yet unique devices: WavelinQ and Ellipsys. This review analyzes the anatomy, pre- and postoperative considerations, fistula creation methods, and outcomes associated with endoAVF. Currently, data are limited with regard to clinical efficacy of endoAVFs when compared to surgical AVFs. However, early data suggest endoAVFs are a useful technique in the creation of AVFs.
RESUMEN
Objective: This longitudinal study aimed to investigate parental distress and parenting stress in relation to parental perception of child vulnerability (PPCV) in youth with spina bifida (SB). Methods: Parents of 140 youth with SB (ages 8-15 years at Time 1) were recruited as part of a longitudinal study; data were collected at two time points, spaced 2 years apart. Mothers and fathers completed questionnaires assessing levels of personal distress, parenting stress, and PPCV. Results: Mothers and fathers reported similar levels of personal distress, parenting stress, and PPCV, but reports of PPCV increased over time. For mothers, both personal distress and parenting stress were significantly associated with PPCV cross-sectionally, but not longitudinally. For fathers, there were significant cross-sectional and longitudinal associations between parenting stress and PPCV. The cross-sectional association between maternal parenting stress and PPCV was moderated by age, with a significant association only for older youth. Conclusions: For parents of youth with SB, personal distress, and parenting stress are related to parental perceptions of child vulnerability, and child age may moderate this relationship. Parental personal distress and parenting stress are important targets for future interventions.
