Long-Term Results of Complex Abdominal Aortic Aneurysm Open Repair.

This study investigated the long-term outcomes of patients treated with open surgical repair for complex abdominal aortic aneurysms (c-AAAs). A total of 119 patients with c-AAAs undergoing repair between January 2010 and June 2016 in a high-volume aortic center were included. The long-term imaging follow-up consisted of yearly abdominal ultrasound examinations and 5-year computed tomography angiography. At a median follow-up of 76 months (IQR 38 months), forty-three deaths (37%) and three (2.5%) aortic-related deaths were observed. Long-term chronic renal decline was observed in fifty (43.8%) patients, significantly correlated with post-operative acute kidney injury. During the follow-up, five reinterventions (4.3%) were performed. The present study suggests that open c-AAA repair can be performed with acceptable operative risk with durable results. To achieve the best possible long-term outcome, the open surgery repair of complex AAA should be performed in high-volume aortic centers and tailored to the patient.

Type 1A Endoleak after TEVAR in the Aortic Arch: A Review of the Literature.

Aortic arch repair is a challenging intervention. Open surgical repair is still considered the gold standard, but in high-risk patients, it is not always a reasonable option, making endovascular approaches an enticing, when not the only available, alternative for treatment. The strategies more commonly adopted are surgical supra-aortic trunk (SAT) rerouting followed by deployment of a standard thoracic endoprosthesis, chimney techniques, custom-made scalloped, fenestrated, and branched devices, and in situ or physician-modified fenestrations. If we excluded techniques involving SAT rerouting where the arch anatomy is surgically modified in order to make deployment in the aortic arch of a standard thoracic endoprosthesis possible, in the other techniques, one or more SATs are incorporated in the thoracic endoprosthesis. In these cases, no matter what solution is adopted, because of the morphology of the aorta at this level, achieving an ideal sealing is extremely difficult, and endovascular treatments of the arch are burdened by an increased risk of type IA endoleaks. PubMed, EMBASE, and Cochrane Library were searched. We identified 1277 records. After reading titles, abstracts, and full texts, we excluded 1231 records. Exclusion criteria were low-quality evidence, abstracts, case reports, conference presentations, reviews, editorials, and expert opinions. A total of 48 studies were included, for a total of 3114 patients. A type IA endoleak occurred in 248 patients (7.7%) with a mean incidence of 18.8% in chimney procedures, 4.8% and 3%, respectively, in fenestrated and branched devices, and 2.2% in in situ fenestration. We excluded from our analysis scalloped technology that is used when the target vessel originates from a healthy landing zone and represents a different anatomical setting. Type IA endoleaks are a concern with all types of endovascular aortic arch repair, and they can compromise the outcomes of the procedure. The rate of type IA endoleaks appears to be significantly higher in chimney procedures. In order to maximize sealing, whenever possible, endovascular repair of the arch should be achieved with custom-made fenestrated devices. However, chimney configurations are still a valuable solution particularly in the emergency setting, although in such a procedure, to guarantee accurate postoperative management and follow-up, an imaging protocol could be useful.

Through-and-through femorofemoral wire retrograde technique for the E-nside precannulated inner branch thoracoabdominal stent graft.

The E-nside multibranched stent graft (Jotec GmbH, Hechingen, Germany) is the first and only off-the-shelf thoracoabdominal prosthesis with precannulated inner branches. Usually, after the device deployment, target vessel stenting will be facilitated by antegrade inner branch cannulation to retrieve the precannulated guide. In the literature, the use of antegrade access has been associated with the potential risk of cerebral and systemic embolization. Therefore, other retrograde techniques have been described. We have reported a new retrograde approach using a precannulated through-and-through femorofemoral wire technique for target vessel catheterization.

Effectiveness and Safety of Nonmedical Switch From Adalimumab Originator to SB5 Biosimilar in Patients With Inflammatory Bowel Diseases: Twelve-Month Follow-Up From the TABLET Registry.

BACKGROUND: Few data are currently available about SB5 in inflammatory bowel diseases (IBD). The aim of this study was to assess the effectiveness and safety of SB5 in a cohort of patients with IBD in stable remission switched from the adalimumab (ADA) originator and in a cohort of patients with IBD naïve to ADA. METHODS: We prospectively enrolled patients with IBD who started ADA treatment with SB5 (naïve cohort) and those who underwent a nonmedical switch from the ADA originator to SB5 (switching cohort). Clinical remission and safety were assessed at baseline and at 3, 6, and 12 months. In addition, in a small cohort of patients who were switched, we assessed the ADA serum trough levels and antidrug antibodies at baseline, 3, and 6 months. RESULTS: In the naïve cohort, the overall remission rate at 12 months was 60.42%, whereas in the switching cohort it was 89.02%. Fifty-three (36.3%) patients experienced an adverse event, and injection site pain was the most common; it was significantly more frequent in the switching cohort (P = 0.001). No differences were found in terms of ADA serum trough levels at baseline, 3, and 6 months after switching. No patient developed antidrug antibodies after the switch. CONCLUSIONS: We found that SB5 seemed effective and safe in IBD, both in the naïve cohort and in the switching cohort. Further studies are needed to confirm these data in terms of mucosal healing.

"Why We Keep Coming Back": Family and Provider Perspectives on Factors Influencing Long-term Follow-up for Pediatric Cancer Survivorship Care.

PURPOSE: The majority of childhood cancer survivors do not follow-up for long-term risk-based screening for recurrent illness and treatment late effects, despite a high prevalence of secondary morbidities. The primary aim of this study was to investigate factors that influence long-term follow-up for survivorship care, from the perspectives of providers, patients, and caregivers. MATERIALS AND METHODS: A semistructured interview was designed to elicit stakeholder perspectives on factors that facilitate or impede routine clinic visits after completion of cancer therapy. Results were analyzed using a qualitative framework method. RESULTS: Providers, patients, and caregivers identified a wide range of factors that might influence long-term follow-up for care. All respondents noted the importance of efficient clinical operations, resources such as parking, provider behaviors, rapport/attachment, and patient/family logistics. Compared with patients/caregivers, providers more frequently mentioned institutional operations, their own education and skills, patient/family understanding and motivation, and interpersonal processes such as communication style. Families more frequently mentioned clinic environment, and patients more frequently noted the importance of having a family member present, something neither providers nor caregivers reported. CONCLUSIONS: Providers, patients, and patient caregivers have different perspectives regarding factors that may influence follow-up for long-term survivorship care. Understanding these differences can help inform efforts to improve follow-up.

TEVAR for traumatic thoracic injury with the first-generation stent graft.

Thoracic endovascular aortic repair (TEVAR) is a life-saving treatment for blunt thoracic aortic injury. We report long-term outcomes of two young patients who underwent TEVAR for blunt thoracic aortic injury with first-generation thoracic stent grafts. The off-label use of the endograft affected the outcomes: one case of open surgery conversion due to an aortoesophageal fistula and one case of endovascular relining for a voluminous pseudoaneurysm associated with a type III endoleak. Long-term follow-up is crucial in TEVAR, especially in case of a first-generation device used in an urgent setting.

Long-term follow-up of adventitial cyst surgical excision in external iliac vein.

Adventitial cystic disease of the venous system is an extremely rare condition. Forty-five cases have been described in the literature during the last 70 years, but they may not be representative of the real incidence of this pathologic process. We report a case of an adventitial cyst compressing the right external iliac vein and presenting with edema of the ipsilateral leg. Ultrasound imaging and computed tomography angiography showed the typical features of cystic disease and venous stenosis. Cyst excision was performed with a double surgical access. No perioperative complications were reported. There was no recurrence at 4-year follow-up.

Open conversion after Nellix endovascular aneurysm sealing.

The Nellix endovascular aneurysm sealing system (Endologix, Irvine, Calif) was presented as a novel concept in the treatment of abdominal aortic aneurysm. After numerous adverse events, the device was voluntarily withdrawn from the market by the manufacturer. This video describes the technical approach of a successful explantation of the Nellix endograft in a patient who underwent endovascular aneurysm sealing for abdominal aortic aneurysm.

Horseshoe Kidney Protection with Histidine-Tryptophan-Ketoglutarate Solution during Surgical Abdominal Aortic Aneurysm Repair.

CASE REPORT: We report an unusual case of a 65-year-old male patient with horseshoe kidney, who underwent a successful open repair for an abdominal aortic aneurysm (AAA). The accessory renal arteries were perfused with histidine-tryptophan-ketoglutarate (HTK) solution (Custodiol®; Dr. Franz-Kohler Chemie GmbH, Bensheim, Germany) during the vascular reconstruction. There were no creatinine and estimated glomerular filtration rate (eGFR) modifications in the postoperative time. In the literature, only two cases of Custodiol solution for kidney protection during aortic surgery are reported. To the best of our knowledge, this is the first case of Custodiol perfusion for horseshoe kidney protection. DISCUSSION: The concomitant presence of horseshoe kidney and an AAA requires a specific preoperative planning. This is necessary to define the appropriate surgical procedure and strategy. The onset of acute kidney injury is an aspect that must always be taken into consideration during aortic surgery, even more in the case we are reporting. Indeed, despite the complexity of the kidney anatomy, the use of Custodiol solution allowed a proper maintenance of the perioperative renal function, as shown by the postoperative levels of creatinine and eGFR. CONCLUSIONS: Preoperative planning and organ preservation are crucial in AAA open repair, especially in the presence of congenital anomalies such as horseshoe kidney.

Endoanchors under 3D image fusion for a type IA endoleak after EVAR.

The Heli-FX technique for type IA EL under 3D-IF proved to be accurate in terms of EL channel vision and correct endoanchors deployment. The EL volume rendering constant view allowed a precise anchors fixation at the EL channel. 3D-IF confirmed to be a valid help in orientation and navigation during endovascular aortic procedure.

Improving Childhood Cancer Survivor Care Through Web-Based Platforms.

Survivors of childhood cancer are at increased risk for late effects of cancer therapy, but evidence suggests that adherence to follow-up care is suboptimal. Here, we review the barriers to adherence, including those unique to childhood cancer survivors, and the rationale for distribution of a survivorship care plan. We also discuss advantages and potential limitations of delivering survivorship care plans via web-based platforms, and describe the unique features of one of these platforms, Passport for Care. A baseline survey directed toward survivors and conducted through Passport for Care found that a significant proportion of survivors are unaware of their specific health risks resulting from cancer and its treatment, and compared with their parents, are less afraid of the risks of recurrence and of cancer therapy-associated late effects (n = 528). Web-based platforms such as Passport for Care have enormous potential for improving access to health information, as well as for enhancing patient, family caregiver, and healthcare provider awareness of both risks of late effects and recommended surveillance. Results from this survey also suggest the potential utility of leveraging these tools to conduct additional research on consenting survivors.

Lectin Pathway of Complement Activation Is Associated with Vulnerability of Atherosclerotic Plaques.

Inflammatory mechanisms may be involved in atherosclerotic plaque rupture. By using a novel histology-based method to quantify plaque instability here, we assess whether lectin pathway (LP) of complement activation, a major inflammation arm, could represent an index of plaque instability. Plaques from 42 consecutive patients undergoing carotid endarterectomy were stained with hematoxylin-eosin and the lipid core, cholesterol clefts, hemorrhagic content, thickness of tunica media, and intima, including or not infiltration of cellular debris and cholesterol, were determined. The presence of ficolin-1, -2, and -3 and mannose-binding lectin (MBL), LP initiators, was assessed in the plaques by immunofluorescence and in plasma by ELISA. LP activation was assessed in plasma by functional in vitro assays. Patients presenting low stenosis (≤75%) had higher hemorrhagic content than those with high stenosis (>75%), indicating increased erosion. Increased hemorrhagic content and tunica media thickness, as well as decreased lipid core and infiltrated content were associated with vulnerable plaques and therefore used to establish a plaque vulnerability score that allowed to classify patients according to plaque vulnerability. Ficolins and MBL were found both in plaques' necrotic core and tunica media. Patients with vulnerable plaques showed decreased plasma levels and intraplaque deposition of ficolin-2. Symptomatic patients experiencing a transient ischemic attack had lower plasma levels of ficolin-1. We show that the LP initiators are present within the plaques and their circulating levels change in atherosclerotic patients. In particular, we show that decreased ficolin-2 levels are associated with rupture-prone vulnerable plaques, indicating its potential use as marker for cardiovascular risk assessment in atherosclerotic patients.

Dissemination of Evidence From Systematic Reviews Through Academic CME Providers: A Feasibility Study.

INTRODUCTION: Although systematic reviews represent a source of best evidence to support clinical decision-making, reviews are underutilized by clinicians. Barriers include lack of awareness, familiarity, and access. Efforts to promote utilization have focused on reaching practicing clinicians, leaving unexplored the roles of continuing medical education (CME) directors and faculty in promoting systematic review use. This study explored the feasibility of working with CME directors and faculty for that purpose. METHODS: A convenience sample of five academic CME directors and faculty agreed to participate in a feasibility study exploring use in CME courses of systematic reviews from the Agency for Healthcare Research and Quality (AHRQ-SRs). AHRQ-SR topics addressed the comparative effectiveness of health care options. Participants received access to AHRQ-SR reports, associated summary products, and instructional resources. The feasibility study used mixed methods to assess 1) implementation of courses incorporating SR evidence, 2) identification of facilitators and barriers to integration, and 3) acceptability to CME directors, faculty, and learners. RESULTS: Faculty implemented 14 CME courses of varying formats serving 1700 learners in urban, suburban, and rural settings. Facilitators included credibility, conciseness of messages, and availability of supporting materials; potential barriers included faculty unfamiliarity with SRs, challenges in maintaining review currency, and review scope. SR evidence and summary products proved acceptable to CME directors, course faculty, and learners by multiple measures. DISCUSSION: This study demonstrates the feasibility of approaches to use AHRQ-SRs in CME courses/programming. Further research is needed to demonstrate generalizability to other types of CME providers and other systemic reviews.

Understanding Age-based Transition Needs: Perspectives from Adolescents and Adults with Congenital Heart Disease.

OBJECTIVE: The purpose of this study was to explore the transition process in congenital heart disease (CHD) care through the perceived needs and concerns of adolescents (pretransition) and the experiential insight from adults (post-transition), in order to inform future transition initiatives and information delivery methods. DESIGN: In this cross-sectional study, adolescents and adults with moderate or complex CHD participated in semistructured telephone interviews. Interview transcripts were coded using NVivo qualitative data software. SETTING: Single large urban tertiary care CHD center PATIENTS: Adolescents (between 16 and 20 years of age) and adults (21-40 years of age) with moderate or complex CHD. Patients with global developmental delay or known chromosomal abnormalities were excluded. Twenty adolescents and 20 adults participated in the study; each interview allowed for participants to discuss issues relevant to them. RESULTS: Among adolescents, half wanted more CHD information and half were concerned about becoming adults with CHD. All adolescents had access to the Internet via a mobile phone, but only 55% had searched online for CHD information. Adolescents were interested in mentorship with other adolescents (90%) and adults (60%) with CHD either in person or via protected social media. Among adults, 55% were satisfied with the amount of information they had received as adolescents. Areas in which adults would have preferred additional information include longer-term implications of CHD, employment, insurance, family planning, and mental health. CONCLUSIONS: There are similarities and differences in the perceived transition needs of a diverse group of adolescents and adults with CHD. Both cohorts desire additional information during the transition process, including interest in use of a transition checklist to learn about managing their CHD. Adolescents are interested in interactions with other teens and adult mentors with CHD and are open to Internet-based interventions. Web-based initiatives could deliver CHD information and provide a platform for social media mentorship.

Homotaurine in Parkinson's disease.

Homotaurine is a natural compound of red algae, which has been demonstrated to have a neuroprotective effect and has been evaluated as a possible therapeutic agent for Alzheimer's disease. This was a single blind, randomized, controlled study to evaluate the safety and efficacy of homotaurine in patients with Parkinson's disease (PD) and cognitive impairment. Patients were evaluated at baseline and 6 months later. Assessments included, the evaluation of: motor and non-motor conditions and complications (Unified Parkinson's Disease Rating Scale, UPDRS); disability and quality of life; depression; excessive daytime sleepiness and fatigue. An extensive neuropsychological tests battery was administered evaluating specific cognitive domains: memory, phonemic verbal fluency, executive functions and selective visual attention. After baseline testing, patients were allocated to one of the two groups: (A) treatment group: patients treated with homotaurine 100 mg; (B) control group: patients not treated with homotaurine. Forty-seven patients were evaluated at baseline, 24 (51 %) completed the study (PD-homotaurine: n = 11; 44 % and PD-controls: n = 13; 59 %); discontinuation rate was similar across subjects (p = 1.0). Intention to treat analyses to evaluate homotaurine safety showed mild side effects (gastrointestinal upsetting) in 3 patients. Per protocol analyses of homotaurine efficacy showed no difference between groups. Within group analyses showed that PD-homotaurine patients had better score at UPDRS-I at the end of the study compared to baseline (p = 0.017) and at Epworth Sleepiness Scale (p = 0.01). No other differences were found. No significant difference arose for the PD-ctrl group. Homotaurine is a safe drug. Our data suggest a beneficial effect of homotaurine on excessive sleepiness. Future studies are encouraged to confirm this promising role of homotaurine in promoting the sleep/awake cycle in patients with PD.

Epidemiological, clinical, and molecular study of a cohort of Italian Parkinson disease patients: association with glutathione-S-transferase and DNA repair gene polymorphisms.

Parkinson's disease (PD) is one of the most common neurodegenerative disorders whose etiology is multifactorial including both hereditary and environmental factors. Currently, pathogenic mutations in at least five genes have been implicated in familial PD generally accounting for less than 10 % of all PD cases in most populations. It has been suggested that polymorphisms in other genes such as those encoding enzymes involved in oxidative metabolism and detoxification could be involved in predisposition to PD since oxidative stress in dopaminergic neurons is thought to be of central importance in the pathogenesis of the disease. The aim of our work was to study the association of genetic polymorphisms in genes involved in oxidative metabolism and detoxification mechanism, namely GSTM1, GSTT1, GSTP1, and those involved in DNA damage repair, OGG1 and XRCC1, in an Italian cohort of sporadic PD patients. We did not detect any association between GSTT1 and GTTM1 null polymorphisms and PD, whereas the 104GSTP1 polymorphism was associated with PD in male patients but not in females. Furthermore, we detected a protective effect of wild type genotype of XRCC1 in women.
