- Abstract
Objectives: This study investigated whether left ventricular (LV) stimulation via a guidewire-reduced procedure duration while maintaining efficacy and safety compared with standard right ventricular (RV) stimulation., Background: Rapid ventricular pacing is necessary to ensure cardiac standstill during transcatheter aortic valve replacement (TAVR)., Methods: This is a prospective, multicenter, single-blinded, superiority, randomized controlled trial. Patients undergoing transfemoral TAVR with a SAPIEN valve (Edwards Lifesciences, Irvine, California) were allocated to LV or RV stimulation. The primary endpoint was procedure duration. Secondary endpoints included efficacy, safety, and cost at 30 days., Results: Between May 2017 and May 2018, 307 patients were randomized, but 4 were excluded because they did not receive the intended treatment: 303 patients were analyzed in the LV (n = 151) or RV (n = 152) stimulation groups. Mean procedure duration was significantly shorter in the LV stimulation group (48.4 ± 16.9 min vs. 55.6 ± 26.9 min; p = 0.0013), with a difference of -0.12 (95% confidence interval: -0.20 to -0.05) in the log-transformed procedure duration (p = 0.0012). Effective stimulation was similar in the LV and RV stimulation groups: 124 (84.9%) versus 128 (87.1%) (p = 0.60). Safety of stimulation was also similar in the LV and RV stimulation groups: procedural success occurred in 151 (100%) versus 151 (99.3%) patients (p = 0.99); 30-day MACE-TAVR (major adverse cardiovascular event-transcatheter aortic valve replacement) occurred in 21 (13.9%) versus 26 (17.1%) patients (p = 0.44); fluoroscopy time (min) was lower in the LV stimulation group (13.48 ± 5.98 vs. 14.60 ± 5.59; p = 0.02), as was cost (€18,807 ± 1,318 vs. €19,437 ± 2,318; p = 0.001)., Conclusions: Compared with RV stimulation, LV stimulation during TAVR was associated with significantly reduced procedure duration, fluoroscopy time, and cost, with similar efficacy and safety.

- Abstract
Coronary bifurcations are involved in 15-20% of all percutaneous coronary interventions (PCI) and remain one of the most challenging lesions in interventional cardiology in terms of procedural success rate as well as long-term cardiac events. The optimal management of bifurcation lesions is still debated but involves careful assessment, planning and a sequential provisional approach. The preferential strategy for PCI of bifurcation lesions remains to use main vessel (MV) stenting with a proximal optimisation technique (POT) and provisional side branch (SB) stenting as a preferred approach. Final kissing balloon inflation is not recommended in all cases. In the minority of lesions where two stents are required, careful deployment and optimal expansion are essential to achieve a long-term result. Intracoronary imaging techniques (IVUS, OCT) and FFR are useful endovascular tools to achieve optimal results., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

- Abstract
Immunosuppression in kidney transplant recipients with decreased graft function and severe histological vascular changes can be particularly challenging. Belatacept could be a valuable option, as a rescue therapy in this context. We report a retrospective case control study comparing a CNI to belatacept switch in 17 patients with vascular damage and low eGFR to a control group of 18 matched patients with CNI continuation. Belatacept switch was performed on average 51.5 months after kidney transplantation (6.2-198 months). There was no difference between the two groups regarding eGFR at inclusion, and 3 months before inclusion. In the "CNI to belatacept switch group," mean eGFR increased significantly from 23.5 ± 6.7 mL/min/1.73m
2 on day 0, to 30.4 ± 9.1 mL/min/1.73 m2 on month 6 (p < 0.001) compared to the control group, in which no improvement was observed. These results were still significant on month 12. Two patients experienced biopsy-proven acute rejection. One was effectively treated without belatacept discontinuation. Two patients needed belatacept discontinuation for infection. In conclusion, the remplacement of CNI with belatacept in patients with decreased allograft function and vascular lesions is associated with an improvement in eGFR., (© 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.)- Published

- Abstract
Background: Epidemiological data for acute kidney injury are scarce, especially in low-income countries (LICs) and lower-middle-income countries (LMICs). We aimed to assess regional differences in acute kidney injury recognition, management, and outcomes., Methods: In this multinational cross-sectional study, 322 physicians from 289 centres in 72 countries collected prospective data for paediatric and adult patients with confirmed acute kidney injury in hospital and non-hospital settings who met criteria for acute kidney injury. Signs and symptoms at presentation, comorbidities, risk factors for acute kidney injury, and process-of-care data were obtained at the start of acute kidney injury, and need for dialysis, renal recovery, and mortality recorded at 7 days, and at hospital discharge or death, whichever came earlier. We classified countries into high-income countries (HICs), upper-middle-income countries (UMICs), and combined LICs and LMICs (LLMICs) according to their 2014 gross national income per person., Findings: Between Sept 29 and Dec 7, 2014, data were collected from 4018 patients. 2337 (58%) patients developed community-acquired acute kidney injury, with 889 (80%) of 1118 patients in LLMICs, 815 (51%) of 1594 in UMICs, and 663 (51%) of 1241 in HICs (for HICs vs UMICs p=0.33; p<0.0001 for all other comparisons). Hypotension (1615 [40%] patients) and dehydration (1536 [38%] patients) were the most common causes of acute kidney injury. Dehydration was the most frequent cause of acute kidney injury in LLMICs (526 [46%] of 1153 vs 518 [32%] of 1605 in UMICs vs 492 [39%] of 1260 in HICs) and hypotension in HICs (564 [45%] of 1260 vs 611 [38%%] of 1605 in UMICs vs 440 [38%] of 1153 LLMICs). Mortality at 7 days was 423 (11%) of 3855, and was higher in LLMICs (129 [12%] of 1076) than in HICs (125 [10%] of 1230) and UMICs (169 [11%] of 1549)., Interpretation: We identified common aetiological factors across all countries, which might be amenable to a standardised approach for early recognition and treatment of acute kidney injury. Study limitations include a small number of patients from outpatient settings and LICs, potentially under-representing the true burden of acute kidney injury in these areas. Additional strategies are needed to raise awareness of acute kidney injury in community health-care settings, especially in LICs., Funding: International Society of Nephrology., (Copyright © 2016 Elsevier Ltd.

- Abstract
Nontuberculous mycobacteria (NTM) infection is a challenging diagnosis for clinicians in solid organ transplantation. Immune reconstitution inflammatory syndrome (IRIS) is so far unreported in this context. We report here the case of a renal transplant recipient who developed Mycobacterium kansasii-associated lymphadenitis complicated by IRIS while undergoing reduction of his immunosuppressive therapy. For IRIS, the patient required low-dose steroids and an increase in global immunosuppression, in association with NTM antibiotherapy., (© Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.)

- Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is a renal hereditary disorder associated with increased cardiovascular mortality, due to mutations in polycystin-1 and polycystin-2 genes. Endothelial polycystin-deficient cells have an altered mechanosensitivity to fluid shear stress and subsequent deficit in calcium-induced nitric oxide release, prevented by dopamine receptor stimulation. However, the impact of polycystin deficiency on endothelial function in ADPKD patients is still largely unknown. Here we assessed endothelium-dependent flow-mediated dilatation in 21 normotensive ADPKD patients and 21 healthy control subjects, during sustained (hand skin heating) and transient (postischemic hyperemia) flow stimulation. Flow-mediated dilatation was less marked in ADPKD patients than in controls during heating, but it was similar during postischemic hyperemia. There was no difference in endothelium-independent dilatation in response to glyceryl trinitrate. Local plasma nitrite, an indicator of nitric oxide availability, increased during heating in controls but not in patients. Brachial infusion of dopamine in a subset of ADPKD patients stimulated plasma nitrite increase during heating and improved flow-mediated dilatation. Thus, ADPKD patients display a loss of nitric oxide release and an associated reduction in endothelium-dependent dilatation of conduit arteries during sustained blood flow increase. The correction of these anomalies by dopamine suggests future therapeutic strategies that could reduce the occurrence of cardiovascular events in ADPKD.

- Abstract
Background: Aortic regurgitation (AR) is an important complication of transcatheter aortic valve implantation (TAVI) and even moderate AR is associated with increased mortality after TAVI. The association with decreased survival is unclear. We aimed to analyse the impact of AR after TAVI as a function of baseline NT-proBNP., Methods: We included 236 consecutive patients implanted in our centre with the SAPIEN and SAPIEN XT valves, via the transfemoral route. AR was evaluated by transthoracic echocardiography. NT-proBNP was measured 24h before implantation and patients were divided according to the median value., Results: Median age was 85 years (80-89) and 137 (58.1%) were women. Patients with high NT-proBNP had lower left ventricular ejection fraction: 52% (35-65) vs. 63% (55-70), p<0.001, larger telediastolic diameters: 56 mm (49-61) vs. 52 mm (46-56), p=0.01, and more severe aortic stenosis: 0.62 ± 0.15 cm(2) vs. 0.70 ± 0.2 cm(2), p<0.001. Pre-procedural moderate or severe AR (42% vs. 26%, p=0.013) and mitral regurgitation (56% vs. 36%, p=0.004) were more common in the high NT-proBNP group. After TAVI, moderate or severe AR occurred in 26% of patients and was associated with increased 2-year mortality only in the low NT-proBNP group, while patients in the high NT-proBNP group were not affected., Conclusions: Moderate or severe AR after TAVI was not associated with increased 2-year mortality in patients with high baseline NT-proBNP. Our data suggest that the impact of AR after TAVI is absent in patients with significant pre-procedural AR or mitral regurgitation and more severe aortic stenosis., (Copyright © 2014 Elsevier Ireland Ltd.

- Abstract
Among the wide spectrum of congenital abnormalities of coronary arteries, a single coronary artery is often confused with an ectopic coronary artery connected with the contralateral coronary artery. Both abnormalities are characterized by a single coronary ostium, but they differ by the lack or not of an initial ectopic course. The prognosis of anomalous connections of coronary arteries depends mainly on the type of the initial course in relation to other cardiac structures. Therefore, the distinction between a single coronary artery and an ectopic coronary artery connected with the contralateral artery is of importance., (Copyright © 2013 Elsevier Masson SAS.

- Abstract
Objectives: The authors report the feasibility and 30-day outcomes of transfemoral aortic valve replacement (TAVR), using the Edwards SAPIEN (Edwards Lifesciences, Irvine, California) and Edwards SAPIEN XT (Edwards Lifesciences) prosthesis, implanted using exclusively local anesthesia and fluoroscopic guidance., Background: Transfemoral TAVR is often managed with general anesthesia. However, a simplified percutaneous approach using local anesthesia has become more popular because it offers multiple advantages in an elderly and fragile population., Methods: Between May 2006 and January 2011, the authors prospectively evaluated 151 consecutive patients (logistic EuroSCORE: 22.8 ± 11.8%) who underwent TAVR (SAPIEN: n = 78, SAPIEN XT: n = 73) using only local anesthesia and fluoroscopic guidance. The primary endpoint was a combination of all-cause mortality, major stroke, life-threatening bleeding, stage 3 acute kidney injury (AKI), periprocedural myocardial infarction (MI), major vascular complication, and repeat procedure for valve-related dysfunction at 30 days., Results: Transarterial femoral approach was surgical in all SAPIEN procedures and percutaneous in 97.3% of SAPIEN XT, using the ProStar vascular closure device, and was well tolerated in all cases. Conversion to general anesthesia was required in 3.3% (SAPIEN cases) and was related to complications. Vasopressors were required in 5.5%. Procedural success was 95.4%. The combined-safety endpoint was reached in 15.9%, including overall mortality (6.6%), major stroke (2.0%), life-threatening bleeding (7.9%), stage 3 AKI (0.7%), periprocedural MI (1.3%), major vascular complication (7.9%), and repeat procedure for valve-related dysfunction (2.0%) at 30 days. A permanent pacemaker was required in 5.3%., Conclusions: This single-center, prospective registry demonstrated the feasibility and safety of a simplified transfemoral TAVR performed using only local anesthesia and fluoroscopic guidance in high surgical risk patients with severe aortic stenosis., (Copyright © 2012 American College of Cardiology Foundation.

- Abstract
Whether or not a cyclosporine A (CsA)-free immunosuppressant regimen based on sirolimus (SRL) prevents aortic stiffening and improves central hemodynamics in renal recipients remains unknown. Forty-four patients (48 ± 2 years) enrolled in the CONCEPT trial were randomized at week 12 (W12) to continue CsA or switch to SRL, both associated with mycophenolate mofetil. Carotid systolic blood pressure (cSBP), pulse pressure (cPP), central pressure wave reflection (augmentation index, AIx) and carotid-to-femoral pulse-wave velocity (PWV: aortic stiffness) were blindly assessed at W12, W26 and W52 together with plasma endothelin-1 (ET-1), thiobarbituric acid-reactive substances (TBARS) and superoxide dismutase (SOD) and catalase erythrocyte activities. At W12, there was no difference between groups. At follow-up, PWV, cSBP, cPP and AIx were lower in the SRL group. The difference in PWV remained significant after adjustment for blood pressure and eGFR. In parallel, ET-1 decreased in the SRL group, while TBARS, SOD and catalase erythrocyte activities increased in both groups but to a lesser extent in the SRL group. Our results demonstrate that a CsA-free regimen based on SRL reduces aortic stiffness, plasma endothelin-1 and oxidative stress in renal recipients suggesting a protective effect on the arterial wall that may be translated into cardiovascular risk reduction., (©2011 The Authors Journal compilation © 2011 The American Society of Transplantation and the American Society of Transplant Surgeons.)

- Abstract
Introduction: Cryofibrinogenemia may be essential, or secondary to diseases such as neoplasia, infection, thrombosis, and collagen vascular diseases. In a previous study, we reported the occurrence of neoplasia in some essential cryofibrinogenemia patients after a short period of follow-up., Purpose: We performed a prospective multi-center 5-year follow-up study in essential cryofibrinogenemia patients (2005-2009)., Results: 23 patients with essential cryofibrinogenemia were included, mean age 59 years (range: 33-79), 14 males. After a mean follow-up period of 24 months, 11/23 (47%) of cases that were initially diagnosed as essential cryofibrinogenemia were found to have an underlying lymphoma (6 T lymphoma and 5 B lymphoma)., Conclusion: This prospective study suggests that some cases of cryofibrinogenemia that are initially considered as essential, may have underlying lymphoma. Thus, we further suggest that regular follow-up should be performed in patients with essential cryofibrinogenemia., (Copyright © 2011 Elsevier B.V. All rights reserved.)

- Abstract
Degenerative aortic stenosis is the most frequent valvular disease in developed countries. The reference treatment is surgical valve replacement but one third of the patients are not eligible for surgery. Alternative options have been recently proposed using transcatheter valve implantation (transfemoral or trans-apical approaches) in this subset of patients. Two models of valve (balloon expandable or self-expandable) have demonstrated their efficacy and have been implanted to date in over 4000 patients worldwide. These techniques are promising but several issues remain such as the selection of patients, and the safety and durability of the devices currently used.

- Abstract
Long-term survival of patients with chronic lymphocytic leukemia (CLL) is over 10 years, and such patients are thus potential kidney recipients in the case of superimposed end-stage renal disease. However, the renal and patient outcome in this condition is unknown. We report the charts of four patients with CLL who were engrafted in France with a deceased-donor kidney and underwent routine triple immunosuppressive therapy. The results show that these patients developed severe infectious episodes (fatal in one case) and tumoral complications including rapid progression of CLL in two cases. Moreover, the graft may be infiltrated and damaged by monoclonal B cells: one patient lost his graft 14 months after transplantation. Various therapeutic options (modifications of the immunosuppressive regimen, anti-CD20 antibodies, irradiation of the graft) showed little (if any) efficacy. Therefore, we believe that CLL is a too hazardous condition to envisage solid organ transplantation with a routine immunosuppressive regimen, and we propose a more appropriate approach.

Beaulieu LY, Godin M, Laroche O, Tabard-Cossa V, and Grütter P
- Abstract
A working model has been developed which can be used to significantly increase the accuracy of cantilever deflection measurements using optical beam techniques (used in cantilever-based sensors and atomic force microscopes), while simultaneously simplifying their use. By using elementary geometric optics and standard vector analysis it is possible, without any fitted or adjustable parameters, to completely and accurately describe the relationship between the cantilever deflection and the signal measured by a position sensitive photo-detector. By arranging the geometry of the cantilever/optical beam, it is possible to tailor the detection system to make it more sensitive at different stages of the cantilever deflection or to simply linearize the relationship between the cantilever deflection and the measured detector signal. Supporting material and software has been made available for download at http://www.physics.mun.ca/beauliu_lab/papers/cantilever_analysis.htm so that the reader may take full advantage of the model presented herein with minimal effort.

- Abstract
Serum total, ultrafiltrable and protein-bound magnesium, and urinary fractional excretion of magnesium were studied in patients with primary hyperparathyroidism (before and after surgery) and in patients with hyperparathyroidism, malignant hypercalcemia and chronic renal failure with or without hemodialysis. Whereas serum total Mg was unchanged in patients with primary hyperparathyroidism, the ultrafiltrable magnesium concentration was higher than in the control group and higher before than after surgery. The total and the ultrafiltrable magnesium concentrations were highly correlated in the overall patients with Ca-related metabolic disorders, suggesting that renal function had no influence on the relation between these two parameters. Moreover, in malignant hypercalcemia, our results suggested that PTH-like peptides might be less effective than PTH in renal handling of Mg as previously described for Ca.

When administered orally at 20 or 50 mg/kg/day for 20 or 50 days, this analgesic agent had no effect on the renal function, either in intact rats or in animal with reduced renal parenchyma. There is no histological change in the kidneys of the treated animals except some focal dilatations of the distal tubules. The tubular alterations were more important in treated and untreated rats with nephronic reduction. The whole body autoradiographic studies of rats treated with 14C floctafenin showed that liver and kidney accumulate radioactivity, and that the intake of radiolabeled compounds is twice higher in renal cortex than in medulla. This study suggests that the toxicity of floctafenin for the rat kidney is very low or none.

- Abstract
This review is not intended as a complete study of the nephrotoxicity of chemotherapy agents used in the treatment of cancer. The number of these drugs that are cytotoxic has considerably increased in the last few years and our information is incomplete for many of them. We therefore reviewed the observations reported in the literature. Cis-platinum, streptozotocin, methotrexate at high doses, mithramycin and mitomycin are highly nephrotoxic. Other drugs, such as nitrosoureas, celiptium are less nephrotoxic while some appear to rarely induce nephrotoxicity. Anticancer drug nephrotoxicity is characterized by its particular insidiousness, its time of occurrence and its evolution. Since no clinical manifestations accompany the lesions, nephrotoxicity must be sought routinely. It can occur early or late, may be constant as of the first course or appear only after a certain cumulative dose and even occasionally after such a long interval that its cause may appear to be in doubt. The severity of this nephrotoxicity ranges from the usual first minor urinary anomalies to terminal renal failure. The pathophysiogenic mechanisms of the nephrotoxicity remain in most cases obscure. The mode of penetration into the cells is not known. There are fewer data on the interaction between the toxic agent and the cellular metabolism. In most cases, the drug itself in unchanged form does not seem to be the causative agent, which appears rather to be its metabolite. These metabolites are not always identified. Thus nephrotoxicity of antitumoral agents has not been given sufficient attention. Only better knowledge of their action within the kidney will eventually lead to progress in preventing their harmful side effects.

- Abstract
A 35 year-old woman developed severe systemic lupus erythematosus 9 years after thymectomy for myasthenia gravis. "Seric Thymic Factor" (STF) was low; T helpers subset, T helpers/T suppressors ratio and to a lesser extent T suppressors subset were decreased. Suppressor cell function investigated by Concanavaline A lymphocyte reactivity was low. Under cyclophosphamide, plasmapheresis and steroids all clinical and biological symptoms improved but STF remained low; T helpers, T suppressors subsets and T helpers/T suppressors ratio increased but did not reach the normal range. Statistical and immunological arguments suggest that the association between systemic lupus erythematosus and myasthenia gravis did not occur only by chance. Moreover, thymectomy might have played a role by decreasing the number and function of some subpopulations of lymphocytes.

- Abstract
Although compression stockings have long been recognized as a physiologically significant tool for the promotion of venous return from the lower extremity, the role of nonprescription, commercially available support hose has not been assessed in this regard. The present study involved 100 consecutive women with no known prior history of vascular disease, who responded to an advertisement for free evaluation of the venous status of their legs. The subjects, all of whom wore commercial support hose routinely, were screened for the presence of venous disease by means of Doppler ultrasonography, phleborheography, and a detailed history focusing on risk factors and unrecognized symptoms of venous disease. Photoplethysmography (PPG) was then used to evaluate the efficiency of venous return from the lower extremity with and without the support hose in place. Worsening of PPG results occurred in 43% of the women with commercial stockings in place, whereas 23% improved and 34% showed no change. Women 50 years of age and older had a somewhat higher tendency toward poorer PPG results while wearing the support hose. Furthermore, measurements in women who showed evidence of venous disease by an abnormality in one or more of the screening tests were significantly different from the overall group (p = 0.025): 61% exhibited worsening of PPG results when wearing stockings, only 14% showed improvement, and 25% were unchanged. These results suggest that the use of a commercial support hose may be particularly deleterious to older women and is contraindicated in those with evidence of venous disease in the lower extremity.
