Intraoperative Extravascular Ultrasound in the Identification of Flow-Limiting Dissections after Balloon Angioplasty in the Femoropopliteal Segment.

Background: The BIO REACT study is designed to investigate the incremental value of Extravascular UltraSound (EVUS) added to conventional angiography, compared to conventional angiography only for the identification of Flow-Limiting Dissections (FLD) and to evaluate the safety and efficacy of the REsponse Adapted Combination Therapy (REACT) for the treatment of femoropopliteal lesions. Methods: The primary endpoints were the specificity and sensitivity of EVUS added to angiography for the detection of FLD. Secondary endpoints were primary patency of the REACT therapy within 12 months, fCD-TLR, freedom from MAE, major target limb amputations (mTLA) and survival rates within 24 months. Results: A total of 150 patients were included. EVUS added to angiography had an overall sensitivity of 29% and specificity of 93% for the detection of FLD. There was no PSVR cut-off offering a clinically acceptable trade-off between meaningful sensitivity and specificity values for the detection of FLD. At 12 months, treatment with the REACT resulted in primary patency and fCD-TLR of 81.6% and 94.3%, respectively. In addition, freedom from MAE was 94.3% at 12 months. At 24 months, the survival rate was 94.0%. No mTLA was reported up to the 24-month follow-up. Conclusions: The addition of DUS to angiography showed limited value for detecting FLD in femoropopliteal artery disease.

Radial access for peripheral vascular intervention: the S.M.A.R.T. RADIANZ Vascular Stent System.

INTRODUCTION: Radial access is the standard of care for nearly all cardiac catheterization procedures. It improves patient satisfaction, reduces the length of stay, and is associated with fewer complications. However, few devices and tools are available for the treatment of peripheral arterial disease via a transradial approach (TRA). The S.M.A.R.T. RADIANZ Vascular Stent System is among the RADIANZ suite of products, which is aimed at expanding the portfolio of devices to treat peripheral arterial disease. AREAS COVERED: In this Expert review, the following areas will be covered: (1) Current Landscape of peripheral vascular intervention (PVI) using TRA (2) Detailed description of the S.M.A.R.T. RADIANZ Vascular Stent System. (3) Ongoing clinical trials to evaluate safety of this approach. (4) Future directions and current regulatory status. EXPERT OPINION: TRA for PVI is a promising approach. It holds the possibility of substantially improving the care of patients with peripheral arterial disease (PAD). Numerous challenges must be overcome to realize the full potential of a radial-to-peripheral (RTP) approach. The length of devices and the small sheath size are the main constraints of this approach. The results of the ongoing RADIANCY trial will demonstrate the safety, in selected patients, of the RADIANZ suite of products.

Effectiveness of conventional disease-modifying antirheumatic drugs in psoriatic arthritis: A systematic review. / Eficacia de los fármacos antirreumáticos modificadores de la enfermedad sintéticos en artritis psoriásica: una revisión sistemática.

BACKGROUND: Due to the clinical heterogeneity of psoriatic arthritis (PsA), recommendations have been developed by international groups to guide therapeutic decisions of the rheumatologist. The objective of the current systematic review (RS) was to evaluate the evidence of efficacy of disease-modifying antirheumatic drugs (DMARDs) in PsA. METHODS: Literature search in Medline, EMBASE, Cochrane Library, from 2008 to 2014. We included RS, randomized clinical trials and observational studies, in patients with PsA and an evaluation of efficiency of conventional DMARDs (methotrexate, sulfasalazine, leflunomide), according to the following outcomes: peripheral and axial symptoms; peripheral radiological damage; enthesitis according to power Doppler ultrasound or magnetic resonance imaging (enthesitis count before and after therapy); dactylitis; uveitis. RESULTS: Title and abstract were used to retrieve 1,662 documents for this review (Medline, n=433; EMBASE n=1,132; Cochrane, n=97), and 48 studies were selected for detailed reading; finally, 8 studies were included. CONCLUSIONS: Since the studies included are not robust, and there are arguments to support the effectiveness of methotrexate, the evidence observed with the treatment of DMARDs in PsA is not conclusive.

The effect of smoking on clinical and structural damage in patients with axial spondyloarthritis: A systematic literature review.

OBJECTIVES: To evaluate the association between smoking and clinical parameters and structural damage in axial spondyloarthritis (axSpA). METHODS: We systematically searched MEDLINE, EMBASE and Cochrane Library till November 2015. We selected articles that analysed the smoking impact on disease activity, functional status, structural damage, physical mobility and life quality. Independent extraction of articles by 2 authors using predefined data fields was performed. Studies quality was graded according to the Oxford Level of Evidence scale. RESULTS: A total of 17 articles were selected for inclusion: 2 case-control, 11 cross-sectional and 4 prospective cohort studies, which analysed 4694 patients. Weak evidence suggested a smoking effect on pain, overall assessment of health, disease activity, physical mobility and life quality in ankylosing spondylitis (AS). Moderate-good evidence revealed higher HAQ-AS among smokers (0.025units/y; 95% CI: 0.0071-0.0429; p = 0.007). Every additional unit of ASDAS resulted in an increase of 1.9 vs. 0.4 mSASSS units/2y in AS smokers vs. non-smokers. Good evidence revealed that cigarette smoking and smoking intensity was associated with spinal radiographic progression in axSpA [mSASSS ≥2 units/2y: OR = 2.75, 95% CI: 1.25-6.05, p=0.012; mSASSS progression in heavy smokers (>10 cigarettes/d): OR = 3.57, 95% IC: 1.33-9.60, p = 0.012]. CONCLUSIONS: Published data indicate that smoking has a dose-dependent impact on structural damage progression in axSpA. There is worse HAQ among AS smokers compared to non-smokers. Respect to pain, overall assessment of health, disease activity, physical mobility and life quality, although the evidence level is poor, all evidence points in the same direction: smoking AS patients are worse than non-smoking.

Multidisciplinary dermatology-rheumatology management for patients with moderate-to-severe psoriasis and psoriatic arthritis: a systematic review.

The aim of the study was to analyze the efficacy and satisfaction of multidisciplinary dermatology-rheumatology management for patients with moderate-to-severe psoriasis and psoriatic arthritis (PsA). We conducted a systematic literature search in MEDLINE, EMBASE, and Cochrane Library up to September 2015. Selection criteria include (1) adult patients with moderate-to-severe psoriasis and PsA, (2) assessed in a multidisciplinary consultation, (3) comparison with routine separate consultations, and (4) outcome measures to evaluate efficacy and/or satisfaction. Meta-analyses, systematic reviews, clinical trials, cohort studies, and case series were included. The quality of the studies included was graded according to the Oxford Level of Evidence scale. Of 195 articles, three studies complied with the inclusion criteria: two case series and one descriptive study in which 506 patients were evaluated. Patients were referred to the multidisciplinary consultation from dermatology and rheumatology consultations in all but one study, in which primary care was also involved. The reason for the referral was to confirm the diagnosis and/or treatment. Patients were evaluated on a weekly and monthly basis in two and one study, respectively. The evidence obtained is scarce but suggests the efficacy of multidisciplinary consultations in terms of improved skin and joint symptoms after changing treatment (82-56 %), showing higher scores for this type of consultation compared to the usual [4.91 vs. 2.85 (0-5)] and a high level of satisfaction among patients (94 % "very satisfied"). However, waiting times were higher. With the limited evidence found, multidisciplinary management seems to be more effective and more satisfactory for patients with moderate-to-severe psoriasis and PsA than conventional consultations, though this could not be conclusively demonstrated. The results of this review support the benefit of implementing this type of consultation.

Health technology assessment-based development of a Spanish breast cancer patient decision aid.

OBJECTIVES: The aim of this study was to develop a breast cancer Patient Decision Aid (PDA), using a Health Technology Assessment (HTA) process, to assist patients in their choice of therapeutic options, and to promote shared decision making among patients, healthcare professionals, and other interested parties. METHODS: A systematic review (SR) was conducted of existing breast cancer patient Decision Aids encountered in the main scientific journal databases and on institutional Web sites that create PDAs, together with a Qualitative Research (QR) study, using semi-structured interviews and focus group with stakeholders (patients, family members, and health professionals), with the aim of developing a PDA for breast cancer. RESULTS: The SR shows that PDAs in breast cancer not only increase patient knowledge of the illness, leading to more realistic expectations of treatment outcomes, but also reduce passivity in the decision-making process and facilitate the appropriate choice of treatment options in accordance with patient medical and personal preferences. The analysis of QR shows that both breast cancer patients and healthcare professionals agree that surgery, adjuvant treatments, and breast reconstruction represent the most important decisions to be made. Worry, anxiety, optimism, and trust in healthcare professionals were determined as factors that most affected patients subjective experiences of the illness. This HTA was used as the basis for developing a PDA software program. CONCLUSIONS: The SR and QR used in the development of this PDA for breast cancer allowed patients to access information, gain additional knowledge of their illness, make shared treatment decisions, and gave healthcare professionals a deeper insight into patient experiences of the disease.

Economic assessment of cardiac resynchronization therapy.

INTRODUCTION AND OBJECTIVES: Cardiac resynchronization devices have been shown to be effective in treating heart failure. They reduce overall mortality, heart failure mortality and hospitalizations due to heart failure. The aim of this study was to compare the cost-effectiveness of cardiac resynchronization therapy (CRT) with that of optimal drug therapy (ODT) by carrying out an economic assessment in the Spanish healthcare setting. METHODS: An existing model was adapted for use in the Spanish healthcare setting. The effectiveness of cardiac resynchronization therapy was determined from published systematic reviews. The costs of the various interventions were determined using a range of Spanish data sources. The model adopted the perspective of the public health system and the time horizon considered was the remainder of the patient's life. The outcome variables were life-years gained and quality-adjusted life-years (QALYs) gained. RESULTS: Overall, ODT, CRT and CRT with a defibrillator resulted in gains of 2.11, 2.8 and 3.19 QALYs, respectively, at a cost of €11,722, €31,629 and €52,592, respectively. Consequently, each QALY gained with CRT relative to ODT involved the consumption of €28,612 of additional resources. Similarly, the use of CRT with a defibrillator cost an additional €53,547 per QALY relative to CRT without a defibrillator. CONCLUSIONS: The use of CRT without a defibrillator could be a cost-effective alternative to ODT for treating heart failure in a carefully selected group of patients. The study results were sensitive to uncertainties in many of the variables used in the model.

Efficacy of the Da Vinci surgical system in abdominal surgery compared with that of laparoscopy: a systematic review and meta-analysis.

AIM: The main aim of this review was to compare the safety and efficacy of the Da Vinci Surgical System (DVSS) and conventional laparoscopic surgery (CLS) in different types of abdominal intervention. SUMMARY OF BACKGROUND DATA: DVSS is an emerging laparoscopic technology. The surgeon directs the robotic arms of the system through a console by means of hand controls and pedals, making use of a stereoscopic viewing system. DVSS is currently being used in general, urological, gynecologic, and cardiothoracic surgery. METHODS: This systematic review analyses the best scientific evidence available regarding the safety and efficacy of DVSS in abdominal surgery. The results found were subjected to meta-analysis whenever possible. RESULTS: Thirty-one studies, 6 of them randomized control trials, involving 2166 patients that compared DVSS and CLS were examined. The procedures undertaken were fundoplication (9 studies, one also examining cholecystectomy), Heller myotomy (3 studies), gastric bypass (4), gastrectomy (2), bariatric surgery (1), cholecystectomy (4), splenectomy (1), colorectal resection (7), and rectopexy (1). DVSS was found to be associated with fewer Heller myotomy-related perforations, a more rapid intestinal recovery time after gastrectomy-and therefore a shorter hospital stay, a shorter hospital stay following cholecystectomy (although the duration of surgery was longer), longer colorectal resection surgery times, and a larger number of conversions to open surgery during gastric bypass. CONCLUSIONS: The publications reviewed revealed DVSS to offer certain advantages with respect to Heller myotomy, gastrectomy, and cholecystectomy. However, these results should be interpreted with caution until randomized clinical trials are performed and, with respect to oncologic indications, studies include variables such as survival.
