Congenital heart disease (CHD) is the most common and perhaps most widely variable birth defect. Decades of improved CHD care has resulted in a steady growth in the number and complexity of adults with CHD, and many of these patients require lifelong, specialized follow-up care. This begins with successful transition from pediatric-based to adult-based care. Despite the remarkable advances in this field, many adults with CHD still experience lapses in care that have significant health consequences. This review outlines some of the challenges, progress, and areas for improvement in CHD transition medicine. © SLACK Incorporated.

Megalencephaly-capillary malformation (MCAP) and megalencephaly- polymicrogyria-polydactyly-hydrocephalus (MPPH) syndromes are sporadic overgrowth disorders associated with markedly enlarged brain size and other recognizable features. We performed exome sequencing in 3 families with MCAP or MPPH, and our initial observations were confirmed in exomes from 7 individuals with MCAP and 174 control individuals, as well as in 40 additional subjects with megalencephaly, using a combination of Sanger sequencing, restriction enzyme assays and targeted deep sequencing. We identified de novo germline or postzygotic mutations in three core components of the phosphatidylinositol 3-kinase (PI3K)-AKT pathway. These include 2 mutations in AKT3, 1 recurrent mutation in PIK3R2 in 11 unrelated families with MPPH and 15 mostly postzygotic mutations in PIK3CA in 23 individuals with MCAP and 1 with MPPH. Our data highlight the central role of PI3K-AKT signaling in vascular, limb and brain development and emphasize the power of massively parallel sequencing in a challenging context of phenotypic and genetic heterogeneity combined with postzygotic mosaicism. © 2012 Nature America, Inc.

Strategies to effectively treat people with CKD have been identified by conventional clinical research. Despite this evidence, awareness, screening, detection, diagnosis, risk factor control, treatment, and outcomes remain substandard. Translating clinical evidence into actionable measures that reduce the burden of CKD is a pressing need. Expansion from a "bench-to-bedside" paradigm (conventional type 1 translation) to research that encompasses "clinic and community" is the core concept of type 2 translation. Specifically, this is the discipline of identifying factors and using strategies that lead to adoption, maintenance, and sustainability of science-based interventions in practice. This review identifies key elements of type 2 translational research and highlights the current scope of this type of research for CKD. For type 2 translation to achieve the goals of providing high-quality care and better health outcomes, key facilitators (e.g., theory-based frameworks, adaptable interventions, and inclusion of sustainability and evaluation metrics) and essential elements (e.g., multidisciplinary team care, health information technology, and stakeholder engagement) must be integrated. The National Institute of Diabetes and Digestive and Kidney Diseases recently funded five proposals that aim to improve outcomes for people with CKD, focusing on diverse components of the healthcare continuum: patient safety and transitions; delivery of highquality, evidence-based CKD care; and elimination of disparities. The need for type 2 translational research in CKD is urgent because of preventable human suffering and unsustainable costs of providing care. Focus on the theory, framework, and approaches we have suggested may help us meet that challenge. © 2013 by the American Society of Nephrology.

BACKGROUND In the Carotid Revascularization Endarterectomy versus Stenting Trial, we found no significant difference between the stenting group and the endarterectomy group with respect to the primary composite end point of stroke, myocardial infarction, or death during the periprocedural period or any subsequent ipsilateral stroke during 4 years of follow-up. We now extend the results to 10 years. METHODS Among patients with carotid-artery stenosis who had been randomly assigned to stenting or endarterectomy, we evaluated outcomes every 6 months for up to 10 years at 117 centers. In addition to assessing the primary composite end point, we assessed the primary end point for the long-term extension study, which was ipsilateral stroke after the periprocedural period. RESULTS Among 2502 patients, there was no significant difference in the rate of the primary composite end point between the stenting group (11.8%; 95% confidence interval [CI], 9.1 to 14.8) and the endarterectomy group (9.9%; 95% CI, 7.9 to 12.2) over 10 years of follow-up (hazard ratio, 1.10; 95% CI, 0.83 to 1.44). With respect to the primary long-term end point, postprocedural ipsilateral stroke over the 10-year follow-up occurred in 6.9% (95% CI, 4.4 to 9.7) of the patients in the stenting group and in 5.6% (95% CI, 3.7 to 7.6) of those in the endarterectomy group; the rates did not differ significantly between the groups (hazard ratio, 0.99; 95% CI, 0.64 to 1.52). No significant between-group differences with respect to either end point were detected when symptomatic patients and asymptomatic patients were analyzed separately. CONCLUSIONS Over 10 years of follow-up, we did not find a significant difference between patients who underwent stenting and those who underwent endarterectomy with respect to the risk of periprocedural stroke, myocardial infarction, or death and subsequent ipsilateral stroke. The rate of postprocedural ipsilateral stroke also did not differ between groups.

Objectives This paper reviews the published data and reports 3 cases of thrombosis involving CoreValve (Medtronic, Minneapolis, Minnesota) and 1 involving Edward Sapien (Edwards Lifesciences, Irvine, California) devices. Three of these cases had pathological findings at autopsy. Background Only a limited number of cases of valve dysfunction with rapid increase of transvalvular aortic gradients or aortic insufficiency post-transcatheter aortic valve replacement (TAVR) have been described. This nonstructural valvular dysfunction has been presumed to be because of early pannus formation or thrombosis. Methods Through reviews of the published reports and 4 clinical cases, pathological and clinical findings of early valve thrombosis are examined to elucidate methods for recognition and identifying potential causes and treatments. Results This paper presents 4 cases, 2 of which had increasing gradients post-TAVR. All 3 pathology cases showed presence of a valve thrombosis in at least 2 TAV leaflets on autopsy, but were not visualized by transthoracic echocardiogram or transesophageal echocardiogram. One case was medically treated with oral anti coagulation with normalization of gradients. The consequence of valve thrombosis in all 3 pathology patients either directly or indirectly played a role in their early demise. At least 18 case reports of early valve thrombosis have been published. In 12 of these cases, the early treatment with anticoagulation therapy resolved the thrombus formation and normalized aortic pressures gradients successfully. Conclusions These 4 cases elucidate the occurrence of valve thrombosis post-TAVR. Consideration should be given to treatment with dual antiplatelet therapy and oral anticoagulation in patients post-TAVR with increasing mean pressure gradients and maximum aortic valve velocity. Further research should be conducted to create guidelines for antithrombotic therapy following TAVR procedure. © 2015 American College of Cardiology Foundation.

Background Frequent and unnecessary utilization of the emergency department (ED) is often a sign of serious latent patient issues, and the associated costs are shared by many. Helping these patients get the care they need in the appropriate setting is difficult given their complexity, and their tendency to visit multiple EDs. Study Objective We analyzed the cost-effectiveness of a multidisciplinary ED-care-coordination program with a regional hospital information system capable of sharing patients' individualized care plans with cooperating EDs. Methods ED visits, treatment costs, cost per visit, and net income were assessed pre- and postenrollment in the program using nonparametric bootstrapping techniques. Individuals were categorized as frequent (3-11 ED visits in the 365 days preceding enrollment) or extreme (≥ 12 ED visits) users. Regression to the mean was tested using an adjusted measure of change. Results Both frequent and extreme users experienced significant decreases in ED visits (5 and 15, respectively; 95% confidence intervals [CI] 2-5 and 13-17, respectively) and direct-treatment costs ($1285; 95% CI $492-$2364 and $6091; 95% CI $4298-$8998, respectively), leading to significant hospital cost savings and increased net income ($431; 95% CI $112-$878 and $1925; 95% CI $1093-$3159, respectively). The results further indicate that fewer resources were utilized per visit. Regression to the mean did not seem to be an issue. Conclusions When examined as a whole, research on the program suggests that expanding it would be an efficient allocation of hospital, and possibly societal, resources. © 2014 Elsevier Inc.

Over the last few decades, much of the world has experienced an epidemic of obesity. In the year 2008, 1.4 billion people worldwide were overweight, and 500 million were obese. Even more alarming is a fact that in the year 2010, 40 million children under the age of 5 years were overweight or obese. In the same time period, the incidence of CKD has also increased worldwide. Obesity has been recognized as a driving force of another global epidemic-diabetes, the leading cause of ESRD. Recent studies are confirming that in addition to risk associated with diabetes per se, increased body mass index is independently linked to increased risk for various kidney disorders, prominently CKD, but also renal cell carcinoma and nephrolithiasis. The purpose of this article is to review current knowledge regarding adverse effects of obesity on the kidney. © 2013 National Kidney Foundation, Inc.

The number of people diagnosed with diabetes is rising throughout the world, which in turn drives upward the global frequency of diabetic kidney disease (DKD). Individuals with DKD are at an increased risk for premature death, cardiovascular disease, and other severe illnesses that result in frequent hospitalizations and increased health-care utilization. Current treatments concentrate on controlling hyperglycemia and hypertension with the specific use of renin-angiotensin system inhibitors. Although such measures reduce the risk of progressive kidney disease, DKD remains the leading cause of ESRD and the major risk amplifier for death in this population. Therefore, novel therapeutic approaches are urgently needed. Ideas for novel targets for therapy are founded on recent advances in understanding DKD mechanisms that are based on experimental models and human observations. The purpose of this review is to describe the epidemiology and present knowledge of DKD pathophysiology as the basis for novel therapies including inhibitors of Janus kinases (JAK), protein kinase C, fibrosis, advanced glycation end products treatments, and endothelin. © 2014 National Kidney Foundation, Inc.

Purpose: To assess relatively long-term (ie, 1 year) neurocognitive outcomes of patients undergoing carotid artery stent (CAS) placement with cerebral protection. Materials and Methods: Sixty-two patients (19 symptomatic; mean age, 73 years) with significant carotid stenosis (≥ 70% for symptomatic patients, ≥ 80% for asymptomatic patients) underwent CAS placement with embolic protection. Cognitive function was assessed prospectively with use of a battery of standardized tests administered at baseline (1-5 days before CAS endovascular therapy) and at 3, 6, and 12 months after CAS placement. Diffusion-weighted imaging (DWI) was performed before the procedure and within 24 hours after CAS placement. Results: Results of statistical modeling across occasions of measurement indicated significant main effects of occasion for the Dementia Rating Scale (DRS)-2 concept formation (P < .001), memory (P = .029), and total scores (P = .001); the DRS-2 total age- and education-corrected Mayo Older Americans Normative Studies score (P < .001); and the North American Adult Reading Test IQ score (P = .003). The vast majority of patients showed improvement or no change relative to baseline DRS-2 total scores at all time points. No significant relationship between DWI outcomes and cognition scores over time was found. Age influenced improvement on cognitive tests, whereas baseline symptom status did not. Conclusions: Revascularization with a carotid stent and neuroprotection, at a minimum, left cognitive function unchanged in patients receiving a CAS, and in many instances improved it. The preliminary findings of this prospective pilot study should be confirmed with a larger, controlled trial. © 2010 SIR.

Three intraosseous devices have been approved by the Food and Drug Administration for use in adult trauma patients when intravenous access cannot be obtained. Sites of insertion are the sternum (FAST1), proximal tibia and humerus (Big Injection Gun), and proximal and distal tibia and humerus (EZ-IO). Insertion generally requires less than 1 minute, and flow rates up to 125 mL/min can be achieved. The devices are used for emergency resuscitation and should be removed within 24 hours of insertion or as soon as practical after peripheral or central intravenous access has been achieved. Contraindications include fractures or other trauma at the insertion site, prosthetic joints near the site, previous attempts to insert an intra osseous device at the same site, osteoporosis or other bone abnormalities, infections at the proposed site, and inability to identify pertinent insertion landmarks. Primary complications are extravasation of medications and fluids into the soft tissue, fractures caused by the insertion, and osteomyelitis. © 2011 American Association of Critical-Care Nurses.
