Measurement of Advance Directive and Medical Treatment Decision-Making Capacity of Older Adults

The objective of this study was to characterize two components of decisional competence that are relevant to advance directive (AD) completion and medical treatment decision making among a subsample of older adults hospitalized in acute care settings.

Percutaneous closure of patent foramen ovale for migraine headaches refractory to medical treatment

BACKGROUND: Patent foramen ovale (PFO) has been linked to migraine, and several retrospective studies reported an improvement in migraine prevalence or frequency after PFO closure for other reasons, mostly for secondary prevention of paradoxical embolism or following diving accidents. We investigated the outcome of patients undergoing PFO closure solely for migraine headaches refractory to medical treatment. METHODS: Seventeen patients (age 44 +/- 12 years; 76% female; one atrial septal aneurysm) underwent percutaneous PFO closure using the Amplatzer PFO Occluder (AGA Medical Corporation, Golden Valley, MN). An 18-mm device was used in two patients, a 25-mm device in 13, and a 35-mm device in two. The interventions were solely guided by fluoroscopy, without intraprocedural echocardiography. RESULTS: All implantation procedures were successful. There were no peri-procedural complications. Contrast transesophageal echocardiography after Valsalva maneuver at 6 months showed complete PFO closure in 16 patients (94%), whereas a minimal residual shunt persisted in one (6%). During 2.7 +/- 1.5 years of follow-up, no deaths and no embolic events occurred. After PFO closure, migraine headaches disappeared in four patients (24%), and improved in eight additional patients (47%). Three patients (18%) reported a decrease of their headaches by 75%, three patients (18%) a decrease of 50%, and two patients (12%) a decrease of 25%, while headaches remained unchanged in five patients (29%). No patient experienced worsening headaches. Moreover, the prevalence of migraine with aura decreased from 82 to 24% (P = 0.002). CONCLUSIONS: These results suggest that percutaneous PFO closure durably alters the spontaneous course of shunt associated migraine.

Medical treatment of vertebral osteoporosis

Although osteoporosis is a systemic disease, vertebral fractures due to spinal bone loss are a frequent, sometimes early and often neglected complication of the disease, generally associated with considerable disability and pain. As osteoporotic vertebral fractures are an important predictor of future fracture risk, including at the hip, medical management is targeted at reducing fracture risk. A literature search for randomized, double-blind, prospective, controlled clinical studies addressing medical treatment possibilities of vertebral fractures in postmenopausal Caucasian women was performed on the leading medical databases. For each publication, the number of patients with at least one new vertebral fracture and the number of randomized patients by treatment arm was retrieved. The relative risk (RR) and the number needed to treat (NNT, i.e. the number of patients to be treated to avoid one radiological vertebral fracture over the duration of the study), together with the respective 95% confidence intervals (95%CI) were calculated for each study. Treatment of steroid-induced osteoporosis and treatment of osteoporosis in men were reviewed separately, based on the low number of publications available. Forty-five publications matched with the search criteria, allowing for analysis of 15 different substances tested regarding their anti-fracture efficacy at the vertebral level. Bisphosphonates, mainly alendronate and risedronate, were reported to have consistently reduced the risk of a vertebral fracture over up to 50 months of treatment in four (alendronate) and two (risedronate) publications. Raloxifene reduced vertebral fracture risk in one study over 36 months, which was confirmed by 48 months' follow-up data. Parathormone (PTH) showed a drastic reduction in vertebral fracture risk in early studies, while calcitonin may also be a treatment option to reduce fracture risk. For other substances published data are conflicting (calcitriol, fluoride) or insufficient to conclude about efficacy (calcium, clodronate, etidronate, hormone replacement therapy, pamidronate, strontium, tiludronate, vitamin D). The low NNTs for the leading substances (ranges: 15-64 for alendronate, 8-26 for risedronate, 23 for calcitonin and 28-31 for raloxifene) confirm that effective and efficient drug interventions for treatment and prevention of osteoporotic vertebral fractures are available. Bisphosphonates have demonstrated similar efficacy in treatment and prevention of steroid-induced and male osteoporosis as in postmenopausal osteoporosis. The selection of the appropriate drug for treatment of vertebral osteoporosis from among a bisphosphonate (alendronate or risedronate), PTH, calcitonin or raloxifene will mainly depend on the efficacy, tolerability and safety profile, together with the patient's willingness to comply with a long-term treatment. Although reduction of vertebral fracture risk is an important criterion for decision making, drugs with proven additional fracture risk reduction at all clinically relevant sites (especially at the hip) should be the preferred options.

The Development of an Intervention Tool to Address Challenges in the Medical Treatment of Children with Autism .

Challenges in treating children with an autism spectrum disorder (ASD) in medical settings are identified and discussed. Although research supports interventions for children with ASD including positive reinforcement, environmental modification, and visual supports and systems, limited research on the efficacy of these interventions in medical environments and with specific procedures exists. Based on the available intervention literature, this project proposes a picture schedule reinforcement system for use during blood draw procedures for ASD children with diabetes. Future efforts should include increased education for medical providers and health professionals as psychological interventions continue to inform best practices in care for children with ASD in medical settings.
